PART I

ITEM 1.  BUSINESS

     References herein to the "Company" or "Rush Enterprises" mean Rush
Enterprises, Inc., a Texas corporation, its subsidiaries and Associated
Acceptance, Inc., the insurance agency affiliated with the Company, unless the
context requires otherwise.

GENERAL

We are a full-service, integrated retailer of premium transportation and
construction equipment and related services. As the leading supplier of
Peterbilt trucks, we accounted for approximately 20.7% of all new Peterbilt
trucks sold in the United States in 1999. In 1997, we acquired our first John
Deere construction equipment dealership in Houston, Texas and have grown to
become a major supplier of John Deere construction equipment. Through our
strategically located networks of Rush Truck Centers and Rush Equipment Centers,
we provide one-stop service for the needs of our customers, including retail
sales of new and used transportation and construction equipment, as well as
after-market parts sales, service and repair facilities and financing,
leasing/rental, and insurance services.



                                       3
<PAGE>   4


     Our Rush Truck Centers are principally located in high traffic areas along
the southwestern corridor of the United States. Our Rush Equipment Centers are
located in two of the top six construction equipment sales markets in the United
States -- Texas and Michigan. We provide leasing and rental services through our
Rush Leasing and Rental Division at our one-stop Rush Truck Centers and Rush
Equipment Centers. Retail financing of trucks and construction equipment, as
well as a full line of insurance products, are arranged through our Rush
Financial and Insurance Division. Our Rush Retail Division has developed the
one-stop shopping strategy for our farm and ranch supply business.

     Our business strategy, based upon providing the customer with competitively
priced products supported with timely and reliable service, has enabled us since
1996 to increase revenues at a compounded annual growth rate of 33.0% and to
increase earnings at a compounded annual growth rate of 37.5%. We intend to
continue to implement our business strategy, reinforce customer loyalty and
remain a market leader by continuing to develop our Rush Truck Centers and Rush
Equipment Centers as we extend our geographic focus through strategic
acquisitions of new locations and expansions of our existing facilities.

     All of our business operations are currently conducted through five
separate divisions: the Rush Truck Center Division, the Rush Equipment Center
Division, the Rush Leasing and Rental Division, the Rush Financial and Insurance
Division and the Rush Retail Division.

               Rush Truck Center Division. Since commencing operations as a
          Peterbilt heavy-duty truck dealer over 34 years ago, we have grown to
          operate Rush Truck Centers at 36 locations which primarily sell
          Peterbilt Class 8 heavy-duty trucks in the states of Texas, Colorado,
          Oklahoma, California, Louisiana, Arizona and New Mexico. Our Rush
          Truck Centers are strategically located to take advantage of increased
          cross-border traffic between the United States and Mexico resulting
          from implementation of NAFTA in 1994. During 1999, our Rush Truck
          Center Division accounted for approximately $662.5 million, or
          approximately 82.0%, of our total revenues.

               Rush Equipment Center Division. Since commencing operations as a
          John Deere dealer in 1997, we have grown to operate seven Rush
          Equipment Centers located in Texas and Michigan. We provide a full
          line of construction equipment for light to medium sized applications,
          with our primary products including John Deere backhoe loaders,
          hydraulic excavators, crawler dozers and four wheel drive loaders.
          During 1999, our Rush Equipment Center Division accounted for
          approximately $82.7 million, or approximately 10.2%, of our total
          revenues.

               Rush Leasing and Rental Division. We provide a broad line of
          product selections for lease or rent, including Class 8, Class 7 and
          Class 6 Peterbilt trucks, a full array of John Deere construction
          equipment products, including a variety of construction equipment
          trailers and heavy-duty cranes. Our lease and rental fleets are
          offered



                                       4
<PAGE>   5


          primarily through our Rush Truck Centers and Rush Equipment Centers on
          a daily, monthly or long-term basis. During 1999, our Rush Leasing and
          Rental Division accounted for approximately $31.0 million, or
          approximately 3.8%, of our total revenues.

               Rush Financial and Insurance Division. We offer third-party
          financing to assist customers in purchasing a new or used truck or
          piece of construction equipment. Additionally, we sell a complete line
          of property and casualty insurance, including collision and liability
          insurance on trucks, cargo insurance, standard automobile liability
          coverages, and life insurance. During 1999, our Rush Financial and
          Insurance Division accounted for approximately $13.6 million, or
          approximately 1.7%, of our total revenues. Finance and insurance
          revenues have limited direct costs and, therefore, contribute a
          disproportionate share of operating profits.

               Rush Retail Division. During 1998, we created the Rush Retail
          Division in connection with our acquisition of D&D Farm and Ranch
          Supermarket, Inc. ("D&D"). D&D is a one-stop shopping center for farm
          and ranch supplies, serving the greater San Antonio, Texas area. We
          anticipate opening a second D&D store in Houston, Texas in the second
          quarter of 2000. During 1999, our Rush Retail Division accounted for
          approximately $18.6 million, or approximately 2.3%, of our total
          revenues.

     We were founded and incorporated in 1965 in Texas and our three senior
executives jointly have 63 years of experience in the industry. We currently
conduct business through 19 subsidiaries, all of which are wholly-owned,
directly or indirectly, by us. Our principal offices are at 555 IH 35 South, New
Braunfels, Texas, 78130.

INDUSTRY OVERVIEW

We currently operate in two principal markets, heavy-duty trucks and
construction equipment markets, which for new product sales have historically
shown a high correlation to the rate of change in industrial production and
gross domestic product.

     Heavy-Duty Truck Market

     We serve the domestic U.S. heavy-duty truck market which we estimate
exceeded $10 billion in retail sales during 1999. According to data published by
R. L. Polk, an industry research and publication firm, the overall domestic
heavy-duty truck market increased from approximately 184,989 new Class 8
(defined by the American Automobile Manufactures Association as trucks with a
minimum gross vehicle weight rating above 33,000 pounds) unit sales in 1996 to
approximately 247,908 new Class 8 unit sales in 1999 (a 34.0% increase). Within
this market, our primary product line is Peterbilt trucks, which according to
American Truck Dealers accounted for approximately 10.2% of all new heavy-duty
truck registrations in 1999. More specifically, within our primary markets,
according to R. L. Polk, 30,243 new heavy-duty trucks were registered in 1999,
4,832 of which were Peterbilts. Accordingly, within our markets, Peterbilt
trucks achieved an average 16.0% market share, substantially higher than the
national average.



                                       5
<PAGE>   6


     Within the markets we serve, our share of the heavy-duty truck market
increased from 2,871 new unit sales in 1996, or approximately 1.5% of the
overall market share in the domestic United States, to 5,366 new unit sales in
1999, for an overall domestic market share of 2.2%. This represents an 86.9%
increase in unit sales and a 47% increase in market share.

         Typically, Class 8 trucks are assembled by the manufacturer utilizing
certain components manufactured by other companies, including engines,
transmissions, axles, wheels and other components. As trucks and truck
components have become increasingly complex, including the use of computerized
controls and diagnostic systems, the ability to provide state-of-the-art service
for a wide variety of truck equipment has become a competitive factor in the
industry. Such service requires a significant capital investment in advanced
equipment, parts inventory and a high level of training of service personnel.
Additionally, Environmental Protection Agency ("EPA") and Department of
Transportation ("DOT") regulatory guidelines for service processes, including
body shop, paint work and waste disposal, require sophisticated operating and
testing equipment to ensure compliance with environmental and safety standards.
Additionally, we believe that the trend towards increased lease/rental sales
will continue as fleets, particularly private ones, seek to establish
full-service leases or rental contracts under which the lessor/rental company
provides a turn-key service including equipment, maintenance, and potentially,
fuel, fuel tax reporting and other services. As a result, differentiation
between truck dealers has become less dependent on pure price competition and is
increasingly based on their ability to offer a wide variety of trucking
services. These include the ability to provide easily accessible, efficient and
sophisticated truck service and replacement parts, the ability to offer
financing for truck purchases, leasing and rental programs and the ability to
accept multiple unit trade-ins related to large fleet purchases. We believe our
one-stop concept and the size and diversity of our dealer network gives us a
competitive advantage in providing these trucking services.



                                       6
<PAGE>   7


     According to Martin Labbe Associates, a transportation research firm, the
long-term growth rates for Class 8 trucks will approximate 1.9% per year until
the year 2007. Factors, which management believes favor the continued growth in
trucking, include the:

          o    growth in demand for consumer and industrial goods in part as a
               result of the internet which has fostered a desire by consumers
               to receive a wider selection of packages sooner;

          o    competitive pressures for "just in time" manufacturing processes
               where U.S. manufacturers are demanding faster, yet less costly,
               small shipment services.

          o    deregulation in the trucking industry leading to a proliferation
               of freight haulers;

          o    the rise of intermodal service which has established a symbiotic
               relationship between rail and truck service; and

          o    the significant increase of cross-border truck traffic between
               Mexico and the United States since NAFTA became effective in
               January of 1994.

    However, there are signs the trucking industry as a whole, in the year 2000,
will not perform up to the high standards set in 1999. Increased fuel prices and
interest rates have adversely affected truck buyers. This results in fewer new
truck sales, has a negative impact on used truck values, and a corresponding
decrease in finance and insurance revenues for the Company. While we believe we
will perform at a level above our competitors, industry factors will negatively
impact our business.

    Construction Equipment Market

    Through our Rush Equipment Centers, which are authorized John Deere dealers,
we serve the estimated $6.0 billion North American market for retail sales of
construction equipment targeted towards light and medium applications. According
to data compiled by John Deere, approximately 78,458 units of construction
equipment were put into use domestically in 1999 compared to 90,158 in 1998,
representing a 13% decrease. However, in the markets Rush currently serves
construction activity remains strong. John Deere has more than a 24% market
share in those product markets in which it has competitive products.

    John Deere's products are sold primarily through a distribution system
composed of an estimated 73 dealers as of December 31, 1999, compared to
approximately 100 dealers as of December 31, 1998, which operate approximately
420 stores and service centers in North America. John Deere dealerships have the
exclusive right to sell new John Deere equipment and parts within their assigned
area of responsibility, which means competition within a dealer's market comes
primarily from dealers of competing manufacturers and, more recently, rental
companies.



                                       7
<PAGE>   8


    The customer base of John Deere equipment users is diverse and includes
residential and commercial construction businesses, independent rental
companies, utility companies, government agencies, and various petrochemical,
industrial and material supply businesses. Industry statistics state that
approximately 57% of all construction equipment is owned by approximately 20% of
the customer base. Accordingly, John Deere and its dealer group are aggressively
developing more sophisticated ways to serve this large fleet owner.

    Management believes that the estimated size of the construction equipment
rental industry in 1999 is greater than $10 billion and is served by over 10,000
rental companies. Although equipment unit purchases are expected to slow down in
2000, we believe that this industry will continue to grow as companies
increasingly utilize rental companies as a means of outsourcing their equipment
needs so as to reduce their investment in non-core assets. We intend to
capitalize on these trends by operating full service Rush Equipment Centers
which can satisfy the needs of both our large and small customers through a full
range product offering for both sales and rentals.

    Market factors affecting the construction equipment industry include:

          o    levels of commercial, residential, and public construction
               activities;

          o    state and federal highway and road construction appropriations;
               and

          o    the consolidation and growth of the rental business.

BUSINESS STRATEGY

    Operating Strategy. Our strategy is to operate integrated dealer networks
that primarily market Peterbilt heavy-duty trucks or John Deere construction
equipment and provide complementary products and services, by emphasizing the
following key elements:

          o    One-Stop Centers. We have developed our truck and construction
               equipment locations as "one-stop centers" where, at one
               convenient location, our customers can purchase new or used
               heavy-duty trucks or construction equipment, finance, lease
               and/or rent trucks or construction equipment, purchase
               after-market parts and accessories and have service performed by
               factory-certified technicians. We believe that this full service
               strategy also helps to mitigate cyclical economic fluctuations
               because the parts and service sales at our Rush Centers generally
               tend to be less volatile than our new and used truck and
               construction equipment sales. We intend to continue to emphasize
               this one-stop concept.

          o    Branding Program. We employ a branding program for our
               facilities, designating each as a Rush Truck Center or Rush
               Equipment Center through distinctive signage and uniform
               marketing programs, in order to take advantage of our existing
               name recognition and to communicate the standardized high quality
               of our products and reliability of our services throughout our
               dealership networks. Our



                                       8
<PAGE>   9


               branding program extends to our services as well as our
               facilities. For example, we recently initiated a prepaid truck
               maintenance program under the "Rush" name, intended to encourage
               repeat service business at our Rush Truck Centers. We believe
               that this branding strategy will increase our market recognition
               and encourage our customers to utilize multiple locations
               throughout our dealership networks.

          o    Management by Dealership Units. We measure and manage the
               business operations of each of our dealerships according to the
               specific business units operating at that location. At each of
               our dealerships, we operate one or more of the following business
               units: new sales, used sales, parts, service, leasing/rental
               and/or financial services. We believe that this system minimizes
               profit cannibalization across business units, thereby enhancing
               the profitability of all aspects of a dealership and increasing
               our overall operating margins. Operating goals are established
               annually and managers are rewarded for performance accordingly.

          o    Integrated Management Information Systems. In order to
               efficiently operate separate business units within each
               dealership, we rely upon our management information systems to
               determine and monitor appropriate inventory levels and product
               mix at each Rush Center. Each Rush Center maintains a centralized
               real-time inventory tracking system that is accessible
               simultaneously by all locations. Our automated reordering system
               assists each Rush Center in maintaining the proper inventory
               levels and permits inventory delivery to each location, or
               directly to customers, typically within 24 hours from the time
               the order is placed. In addition, by actively monitoring market
               conditions, assessing product and expansion strategies and
               remaining abreast of changes within the market, we are able to
               proactively address market-by-market changes by realigning and,
               if necessary, adding product lines and models.

     Growth Strategy. Through the implementation of our expansion and
acquisition initiatives, we have grown to operate a large, multi-state,
full-service dealership network in the heavy-duty truck and construction
equipment markets. We intend to continue to grow our business internally and
through acquisitions by: (1) expanding the product offerings available at, and
capabilities of, our existing Rush Truck and Rush Equipment Centers; (2) opening
new Rush Truck and Rush Equipment Centers in under-served markets within
geographic areas we currently serve; and (3) acquiring and re-branding existing
third-party dealerships within new, strategically located geographic areas.

          o    Expansion of Product Offerings and Capabilities. We intend to
               continue to expand our product lines within our Rush Truck and
               Rush Equipment Centers by adding those product categories which
               are both complementary to our Peterbilt and John Deere product
               lines and well-suited to the Rush operating model. Historically,
               we expanded into the construction equipment industry based on a
               common customer base among our heavy-duty truck and construction
               equipment purchasers. More recently, we became a dealer of Dorsey
               trailers and have begun to introduce trailer



                                       9
<PAGE>   10


               sales, repair and maintenance services at many of our Rush Truck
               Centers. Other recent and planned product line expansions include
               introducing cranes into our Rush Equipment Centers and Peterbilt
               Class 6 and Class 7 medium duty trucks into our Rush Truck
               Centers.

               We believe that there are many additional examples of similar
               product and service offerings which complement our primary
               product lines. Any product category expansion we pursue must
               satisfy our requirements that the (1) products are of a premium
               brand, (2) products provide opportunities for incremental income
               through related servicing, after-market sales or financing, and
               (3) Rush operating controls can be implemented to enhance the
               financial performance of the business.

          o    Open New Rush Truck and Equipment Centers in Existing Markets. We
               believe that there are opportunities to increase our share of the
               heavy-duty truck and construction equipment markets by
               introducing our one-stop centers to under-served markets within
               the southwest United States and within Michigan. We are currently
               planning to expand existing Rush Truck Centers and/or to open new
               facilities in our existing areas of responsibility in Colorado,
               Texas, Oklahoma and California. Construction equipment expansion
               is currently planned or underway at two of our Rush Equipment
               Centers in Michigan.

               Additional dealerships would enable us to enhance revenues from
               our existing customer base as well as increase the awareness of
               the Rush brand name for new buyers. We believe there would also
               be opportunities for cost savings by integrating the inventory
               management and operations of these new locations with those of
               our existing networks.

          o    Expand into New Geographic Areas. We plan to continue to expand
               our Rush Truck and Rush Equipment Center networks by acquiring
               additional dealerships in geographic areas contiguous to our
               current operations or otherwise strategically located along major
               interstate highways. Thus far, we have successfully expanded our
               presence from our Texas base into the southwest and, more
               recently, into Michigan, Arizona, New Mexico and California. We
               believe the geographic diversity of our networks has
               significantly expanded our customer base while ameliorating the
               effects of certain local economic cycles. Geographic
               diversification supports the sale of heavy-duty trucks,
               construction equipment and related parts by allowing us to
               allocate our inventory among the geographic regions we serve
               based on market demand.

               In identifying new areas for expansion, we analyze the target
               market's level of new heavy-duty truck registrations and
               construction equipment purchases, customer buying and leasing
               trends and the existence of competing franchises. We also assess
               the potential performance of a parts and service center to
               determine whether a market is suitable for a Rush dealership.
               After a market has been strategically reviewed, we survey the
               region for a well-situated location. Whether



                                       10
<PAGE>   11


               we acquire existing dealerships or open new Rush locations, we
               will introduce the Rush branding program and implement our
               integrated management system. Geographic expansion is a primary
               means by which we intend to continue to grow our core business.

         Our administrative offices are currently situated in 24,074 square feet
of leased space in New Braunfels, Texas. We also occupy 3,750 square feet of
leased space in San Antonio, Texas as administrative offices for our insurance
services. The D&D Farm and Ranch Supermarket in Seguin, Texas occupies 26,900
square feet of owned building space and we plan to open a second D&D store
occupying 66,000 square feet of owned building space in Houston, Texas in April
2000. In addition to our Rush Equipment Center in Ellsworth, Michigan, we also
operate a John Deere commercial and consumer equipment location in Ellsworth,
Michigan, occupying 6,000 square feet of leased space. We also own a ranch of
approximately 5,700 acres in Cotulla, Texas.

    RUSH OPERATING DIVISIONS

    We are managed and operated though five distinct divisions, which are
described below.

    Rush Truck Center Division

    Our Rush Truck Center Division is the operating division responsible for
sales of new and used heavy-duty trucks, as well as related parts and services.

    New Truck Sales. New heavy-duty truck sales represent the largest portion of
our business, accounting for approximately $466.1 million, or approximately
57.7%, of our total revenues for 1999. Rush Truck Centers primarily sell new
Class 8 heavy-duty Peterbilt trucks, which constitute more than 98% of all new
trucks sold by us. A new Peterbilt Class 8 heavy-duty truck typically sells at a
premium, within a typical price range of $65,000 to $115,000, as compared to
other Class 8 heavy-duty trucks which typically sell within a price range of
$57,000 to $110,000. The average delivery times for custom-ordered new Peterbilt
trucks can vary between 60 days to six months. We also sell Class 7 Peterbilt
trucks, Peterbilt refuse chassis and cement mixer chassis, GMC medium-duty
trucks and, at our Oklahoma Rush Truck Centers, Volvo Class 8 heavy-duty trucks.
Our customers use heavy-duty trucks to haul virtually all materials, including
general freight, petroleum, wood products, refuse and construction materials for
both over-the road and off-road applications.



                                       13
<PAGE>   14


    Approximately 65% of our new truck sales are to fleet customers (defined as
customers who purchase more than five trucks in any single 12-month period).
Because of our large size, strong relationships with our fleet customers and
ability to handle large quantities of used truck trade-ins, we are able to
successfully market and sell to fleets nationwide. We believe that we have a
competitive advantage over most other dealers in that we can absorb multi-unit
trade-ins often associated with fleet sales of new trucks and effectively
disperse the used trucks for resale throughout our dealership network. We
believe that our attention to customer service and our broad range of trucking
services, including our ability to offer truck financing and insurance to our
customers, has resulted in a high level of customer loyalty. Management believes
that approximately 70% of our truck sales during 1999 were to repeat customers.

    Used Truck Sales. Used truck sales accounted for approximately $88.4
million, or approximately 10.9%, of our total revenues for 1999. We primarily
sell used Class 8 heavy-duty trucks manufactured by the leading truck
manufacturers in the industry, including Peterbilt, Kenworth Truck Co., a
division of PACCAR, Inc. ("Kenworth"), Freightliner Corporation, a subsidiary of
Daimler Chrysler AG ("Freightliner"), Mack Trucks, Inc. ("Mack") and Navistar
International Corporation ("Navistar"). Our management believes that we are well
positioned to market used heavy-duty trucks due to our ability to recondition
used trucks for resale utilizing the parts and service departments at our Rush
Truck Centers and to reallocate our used truck inventory from one Rush Truck
Center to another in order to satisfy customer demand. Approximately 80% of our
used truck fleet is comprised of trucks taken as trade-ins from new truck
customers to be used as all or part of such customer's down payment, with the
remainder of our used truck fleet being purchased from third parties for resale.

    Truck Parts and Service. Truck-related parts and service revenues accounted
for approximately $107.1 million, or approximately 13.8%, of our total revenues
for 1999. We are the sole authorized Peterbilt parts and accessories supplier in
each of the markets serviced by our Rush Truck Centers. The parts business
augments our sales and service functions and is a source of recurring revenue.
Each Rush Truck Center carries in its inventory a wide variety of Peterbilt and
other truck parts, with an average of approximately 5,000 items from over 50
suppliers at each location. Rush Truck Centers offer "menu" pricing of service
and body shop functions and offer expedited service at a premium price for
certain routine repair and maintenance functions.

    Our Rush Truck Centers also feature various combinations of fully-equipped
service and body shop facilities, the configuration of which may vary by
location, capable of handling a broad range of truck repairs on most makes and
classes of trucks. Each Rush Truck Center is a Peterbilt designated warranty
service center and most are also authorized service centers for other
manufacturers, including Caterpillar, Inc., Cummins Engine, Inc., Detroit Diesel
Corporation, Eaton Corporation and Rockwell International Corporation. We have a
total of approximately 409 service bays, including 13 paint bays, throughout our
Rush Truck Center network.



                                       14
<PAGE>   15


    We perform both warranty and non-warranty service work, with the cost of the
warranty work being reimbursed by the manufacturer at retail consumer rates. We
estimate that approximately 20% of our truck service functions are performed
under manufacturers' warranties. All service performed at our Rush Truck Centers
is done by technicians who have been certified by our suppliers. We recently
initiated a multi-year prepaid program for certain truck maintenance services
under the "Rush" brand name, with guaranteed pricing and priority service at
Rush Truck Centers. We believe that this program will increase customer traffic,
customer loyalty and enhance service and parts revenue.

    Rush Equipment Center Division

    Our Rush Equipment Center Division is the operating division responsible for
sales of new and used construction equipment as well as related parts and
services.

    New Construction Equipment Sales. New construction equipment sales accounted
for approximately $50.4 million, or approximately 6.3%, of our total revenues
for 1999. Our Rush Equipment Centers carry a complete line of John Deere
construction equipment. A new piece of John Deere construction equipment
typically ranges in price from $20,000 for a skidsteer to $500,000 for an
excavator. We augment our John Deere product line by also carrying a full line
of complementary construction equipment manufactured by other suppliers. We sell
to a diverse customer base including residential and commercial construction
businesses, utility companies, government agencies, and various petrochemical,
industrial and material supply businesses. We believe that many of our Rush
Truck Center customers also utilize construction equipment, and we aggressively
market our construction equipment product offerings to these customers as well
as to the regional truck fleets that we serve.

    We believe that John Deere's reputation for manufacturing quality
construction equipment attracts new and repeat customers who value lower
maintenance and repair costs and a higher residual value at trade-in. We augment
this product loyalty with an operating strategy similar to our Rush Truck
Centers which focuses on providing fast, reliable service in a familiar setting.
As we expand our geographic presence, we believe that our operating strategy
will enable us to both increase our customer base and to generate repeat
business for all product offerings.

    Used Construction Equipment Sales. Used construction equipment sales
accounted for approximately $11.6 million, or approximately 1.4%, of our total
revenues for 1999. We sell used construction equipment manufactured by several
of the leading manufacturers, including John Deere, Case Corporation ("Case"),
Caterpillar, and Komatsu, Ltd. ("Komatsu"). The majority of our used
construction equipment inventory is derived from our rental fleet, and the
remainder taken as trade-ins from our construction equipment customers, which
affords us the opportunity to use our parts and service departments for
reconditioning of used equipment.

    Construction Equipment Parts and Service. Construction equipment-related
parts and service revenues accounted for approximately $19.1 million, or
approximately 2.4%, of our total revenues for 1999. Each Rush Equipment Center
carries in its inventory a wide variety of John Deere and other parts, with over
12,000 items from over 15 suppliers at most locations. We are



                                       15
<PAGE>   16


the sole authorized John Deere parts and accessories supplier in each of our
construction equipment markets. We also maintain a fully equipped John Deere
designated warranty service operation capable of handling repairs on most types
of construction equipment at each of our Rush Equipment Centers. We augment this
presence with field service trucks and technicians who are capable of making
on-site repairs at our customers' location.

    Rush Leasing and Rental Division

    Our Rush Leasing and Rental Division is the operating division responsible
for the leasing and rental of heavy-duty trucks and construction equipment.

    Truck Leasing and Rental. Truck leasing and rental revenues accounted for
approximately $23.3 million, or approximately 2.4%, of our total revenues for
1999. We engage in full-service Peterbilt truck leasing under the PacLease trade
name at eight of our Rush Truck Centers and are the largest PacLease dealer in
the United States. One of the benefits of our leasing and rental division is
that such customers provide an additional "captive" market for our parts and
service operations by creating additional parts sales and service work at Rush
Truck Centers for trucks leased or rented by such customers. All of our leases
require all parts sales, service and maintenance for the leased trucks to be
performed at our facilities (or at facilities outside our service area, as we
direct). Trucks subject to shorter term rentals are also generally serviced at
our facilities. We have increased our lease and rental fleet from less than 100
trucks in 1993 to approximately 845 trucks at December 31, 1999. As of December
31, 1999, we owned approximately 33.7% of our lease and rental fleet, and leased
the remaining trucks in our fleet directly from Peterbilt. Currently, the
average age of trucks in our lease and rental fleet is approximately 28 months.
Generally, we hold trucks in our lease and rental fleet for approximately five
years and then sell such used trucks to the public through our used sales
operations at our Rush Truck Centers. We have consistently realized gains on the
sale of such trucks in excess of the cost of the purchase option contained in
our leases with Peterbilt or the book value of trucks owned by the Company.

    Construction Equipment Rental. Construction equipment rental revenues
accounted for approximately $7.7 million, or approximately 1.0%, of our total
revenues for 1999. Our rental contracts require that all parts sales, service
and maintenance for our rental construction equipment be performed at our
facilities or at other facilities as we direct. Thus, construction equipment
rental customers create additional parts sales and service work at our Rush
Equipment Centers. Our construction equipment rental fleet consisted of
approximately 266 pieces of equipment as of December 31, 1999. Currently, the
average age of the construction equipment in our rental fleet is approximately
thirteen months.

    We offer our customers both long-term and short-term rentals, as well as
rental purchase options. We believe that our rental operations will continue to
benefit from the current trend among our construction equipment customers to
outsource operations, including construction equipment ownership, in order to
minimize their capital investment in construction equipment, as well as reducing
or eliminating the down-time, maintenance, repair and storage costs associated
with construction equipment ownership. We believe that the availability of a
well-maintained rental fleet allows our customers to more effectively manage
their business operations and assets by obtaining construction equipment on an
as-needed basis.



                                       16

    Rush Financial and Insurance Division

    Our Rush Financial and Insurance Division is the operating division
responsible for arranging third-party financing and insurance for both our
heavy-duty truck and construction equipment product offerings.

    We offer our customers products which assist them in purchasing new or used
trucks and construction equipment. This division accounted for approximately
$13.6 million, or approximately 1.7%, of our total revenues for 1999. Finance
and insurance revenues have limited direct costs and, therefore, contribute a
disproportionate share of operating profits.

    New and Used Truck and Construction Equipment Financing. Through Associates
Commercial Corporation, the largest third-party provider of heavy-duty truck
financing in North America ("Associates"), and PACCAR Financial, we arranged
customer financing for approximately $254.4 million, or 45.9%, of our total new
and used truck sales in 1999, an increase of 38.6% from approximately $183.6
million in 1998. Approximately 64% of these truck financings related to new
truck sales and the remainder related to used truck sales. Generally, truck
financings are memorialized through the use of installment contracts, which are
secured by the trucks financed, and generally require a down payment of 10% to
30% of the value of the financed truck, with the remaining balance financed over
a two-to five-year period.

    In addition, through The CIT Group, Associates, John Deere Credit and
others, we arranged customer financing for approximately $29.2 million, or
approximately 47.1%, of our total new and used construction equipment sales in
1999. Approximately 70% of these construction equipment financings related to
new construction equipment sales and the remainder related to used construction
equipment sales. Generally, construction equipment financings are memorialized
through the use of installment or lease contracts, which are secured by the
construction equipment financed, and generally require a down payment of 0% to
10% of the value of the financed piece of construction equipment, with the
remaining balance being financed over a three-to five-year period. All finance
contracts for construction equipment are assigned without recourse.

    Over the last five years, the default rate on the truck financings that we
originated has averaged less than 0.5% per year. Our aggregate liability for
repossession losses resulting from defaults is limited to $500,000 per year for
contracts sold to Associates and $200,000 per year for contracts sold to PACCAR
Financial. Historically, our losses have been significantly less than the amount
of our total maximum recourse liability. We experience no repossession loss on
construction equipment financings that we originate because such financings are
sold to third parties without recourse.

    Insurance Agency Services. We sell a complete line of property and casualty
insurance, including collision and liability insurance on trucks, cargo
insurance, standard automobile



                                       17
<PAGE>   18


liability coverages, life insurance, credit life insurance and health insurance,
workers' compensation coverages and homeowners' insurance. Our agents are
licensed in the states of Texas, Colorado, California, Oklahoma, Louisiana,
Arkansas, New Mexico and Alabama to sell insurance for various insurance
companies, including Associates Insurance and Motors Insurance Corporation, a
subsidiary of GMC. While our focus is on trucking-related insurance products
marketed to our customers, we also sell non-trucking related insurance products
to our customers as well as to the general public. We experienced an average
renewal rate of 79% during 1999.

    Rush Retail Division

     Our Rush Retail Division is the operating division responsible for our
investments in retail stores, which offer a broad range of supplies for farm and
ranch owners.

     Our Rush Retail Division operates our D&D Farm and Ranch Supermarket which
serves the greater San Antonio, Texas area. Building on our "one-stop" strategy,
our D&D Farm and Ranch Supermarket offers a wide variety of indoor and outdoor
farm and ranch supplies, clothing, tack, hardware and, among other items, horse
trailers. Our Retail Division accounted for approximately $18.6 million, or
approximately 2.3%, of our total revenues for 1999. We currently anticipate
opening a second D&D Farm and Ranch Supermarket in Houston, Texas in 2000.

SALES AND MARKETING

     Our established expansion and acquisition strategy and long history of
operations in the heavy-duty truck business have resulted in a strong customer
base that is diverse in terms of geography, industry and scale of operations.
Our Rush Truck Center customers include owner-operators, regional and national
fleets, corporations and local governments. During 1999, no single Rush Truck
Center customer accounted for more than 15% of our total truck sales by dollar
volume. Our Rush Equipment Centers' customer base is similarly diverse and,
during 1999, no single Rush Equipment Center customer accounted for more than 3%
of our total construction equipment sales by dollar volume. We generally promote
our products and related services through our sales staff, trade magazine
advertisements and attendance at industry shows.

We believe that the consistently reliable service received by our customers and
our longevity and geographic diversity have resulted in increased market
recognition of the "Rush" brand name and have served to reinforce customer
loyalty and continuing customer relationships. During 1999, approximately 70% of
our truck sales were to previous or existing customers. In an effort to enhance
our name recognition and to communicate the standardized high level of quality
products and services provided at our Rush Centers, we implement our brand name
concept at each of our dealerships, such that each of our dealerships is
identified as either a Rush Truck Center or Rush Equipment Center. Currently, we
are making a concerted effort to target our products and services to existing
truck customers that are also involved in the construction business. For
example, in Houston, Texas we believe that approximately 40% of our Rush Truck
Center customers have also been customers at the Houston Rush Equipment Center.



                                       18

FACILITY MANAGEMENT

    Personnel. Each Rush Truck and Equipment Center is managed by a general
manager who oversees the operations, personnel and the financial performance of
the location, subject to the direction of the Company's corporate office. Each
Rush Truck Center is also typically staffed by a sales manager, parts manager,
service manager, sales representatives, parts employees, and other service and
make-ready employees. The sales staff of each Rush Truck and Equipment Center is
compensated on a salary plus commission basis, with a high percentage of
compensation based on commission, while the general manager, parts manager and
service manager receive a combination of salary and performance bonus, with a
high percentage of compensation based on the performance bonus. The Company
believes that its employees are among the highest paid in their respective
industries.

    General managers annually prepare detailed monthly forecasts and monthly
profit and loss statements based upon historical information and projected
trends and an element of each general manager's compensation is determined by
meeting or exceeding these operating plans. During the year, general managers
regularly review their facility's progress with senior management and make
appropriate adjustments as needed. All employees of the Company undergo annual
performance evaluations.

    The Company has been successful in retaining its senior management, general
managers and other employees. The average tenure of the Company's current senior
management is 12 years, and the average tenure of its current truck centers'
general managers is approximately 8 years. To promote communication and
efficiency in operating standards, general managers and members of senior
management attend several Company-wide strategy sessions per year. In addition,
management personnel attend various industry-sponsored leadership and management
seminars and receive continuing education on Peterbilt products, John Deere
products, marketing strategies and management information systems.

    Members of senior management regularly travel to each location to provide
on-site management and support. Each location is audited twice a year for
administrative record-keeping, human resources and environmental compliance
matters. The Company has instituted succession planning pursuant to which
employees in each Rush Truck and Equipment Center are groomed as assistant
managers to assume management responsibilities in existing and future
dealerships.

    Purchasing and Suppliers. The Company believes that pricing is an important
element of its marketing strategy. Because of its size, the Rush Truck Center
Division benefits from volume purchases at favorable prices that permit it to
achieve a competitive pricing position in the industry. The Company purchases
its Peterbilt heavy-duty truck inventory and Peterbilt parts and accessories
directly from PACCAR. All other manufacturers' parts and accessories, including
those of Cummins, Detroit Diesel, Caterpillar and others are purchased through
wholesale vendors or from PACCAR, who buys such products in bulk for resale to
the Company and other Peterbilt dealers. All purchasing, volume and pricing
levels and commitments are negotiated by



                                       19
<PAGE>   20


the Company's corporate headquarters. The Company has been able to negotiate
favorable terms, which facilitates the Company's ability to offer competitive
prices for its products.

    The Company purchases all of its John Deere construction equipment inventory
and John Deere parts directly from John Deere. All other construction equipment
manufacturers' parts and accessories are purchased through wholesale vendors by
the Company. Management believes as the network of Rush Equipment Centers is
developed, the Company will be able to negotiate favorable price terms through
volume purchasing, thereby achieve a competitive pricing position in the
industry.

    Management Information Systems. Each Rush Truck and Equipment Center
maintains a centralized real-time inventory tracking system which is accessible
simultaneously by all locations and by the Company's corporate office. The
Company utilizes the information assimilated from its management information
systems to determine and monitor the appropriate inventory level at each
facility. From this information, management has developed a model reflecting
historic sales levels of different product lines. This information identifies
the appropriate level and mix of inventory and forms the basis of the Company's
operating plan. The Company's management information systems and databases are
also used to monitor market conditions, sales information and assess product and
expansion strategies. Information received from state and regulatory agencies,
manufacturers and industry contacts allows the Company to determine market share
statistics and gross volume sales numbers for its products as well as those of
competitors. This information impacts ongoing operations by allowing the Company
to remain abreast of changes within the market and allows management to react
accordingly by realigning product lines and by adding new product lines and
models.

    Distribution and Inventory Management. The Company utilizes its real-time
inventory management tracking system to maintain a close link between each Rush
Truck Center. This link allows for a timely and cost-effective sharing of
managerial and sales information as well as the prompt transfer of inventory
among various locations. The transfer of inventory reduces delays in delivery,
helps maximize inventory turns and assists in controlling problems created by
overstock and understock situations. The Company is linked directly to its major
suppliers, including PACCAR, GMC, and John Deere via real-time satellite or
frame relay communication links for purposes of ordering and inventory
management. These automated reordering and satellite communication systems allow
the Company to maintain proper inventory levels and permit the Company to have
inventory delivered to its locations, or directly to customers, typically within
24 hours of an order being placed.

RECENT ACQUISITIONS

      In December 1999, the Company purchased substantially all the assets of
Norm Pressley's Truck Center, ("Pressley"), which consisted of three dealership
locations in San Diego, Escondido and El Centro, California. The transaction was
valued at approximately $4.5 million with the purchase price paid in cash. An
additional $700,000 consideration may be paid based on a performance based
objective.



                                       20
<PAGE>   21


     In October 1999, the Company purchased substantially all the assets of
Southwest Peterbilt, Inc., Southwest Truck Center, Inc., and New Mexico
Peterbilt, Inc., ("Southwest") a Peterbilt truck dealer, which consisted of five
dealership locations in Arizona and New Mexico. The transaction was valued at
$23.9 million with the purchase price paid in a combination of cash and the
Company's common stock. An additional $4.0 million may be paid based on a
performance based objective.

     In September 1999, the Company acquired substantially all the assets of
Calvert Sales, Inc., (Calvert), a John Deere construction equipment dealership.
The acquisition encompasses 13 counties in eastern Michigan, including two
full-service dealerships located in the Detroit and Flint areas. The transaction
was valued at $11.1 million with the purchase price paid in a combination of
cash and notes payable.

    In September 1998, the Company purchased substantially all of the assets of
Klooster Equipment, Inc. which consisted of three full-service construction
equipment dealerships and one retail only location covering 54 counties in
western Michigan. The purchase price was approximately $13.1 million funded by
(i) $2.5 million of cash, (ii) $9.8 million of borrowings under the Company's
floor plan financing arrangements with Associates Commercial Corporation and
John Deere Inc., and (iii) $836,000 of borrowings from John Deere Credit Corp.

     In March 1998, the Company purchased all of the outstanding stock of D&D
Farm and Ranch Supermarket, Inc. for approximately $10.5 million, with the
purchase price being a combination of cash, notes payable and options to
purchase common stock. The Company accounted for the acquisition as a purchase.

     In October 1997, the Company purchased certain assets and assumed certain
liabilities of C. Jim Stewart & Stevenson, Inc., and Stewart & Stevenson Realty
Corp., which primarily consisted of one full-service John Deere dealership in
Houston, Texas. The purchase price was approximately $30.2 million, funded by
(i) $4 million of cash, (ii) $21.1 million of borrowings under the Company's
floor plan financing arrangement with Associates Commercial Corporation and John
Deere Inc., (iii) $3,080,000 in real estate borrowings from Frost National Bank,
and (iv) a $2,062,500 promissory note payable to the seller.

     In March 1997, the Company purchased the assets of Denver Peterbilt, Inc.,
which consisted of two full-service Peterbilt dealerships in Denver and Greeley,
Colorado. The purchase price was approximately $7.9 million, funded by (i) $6.5
million of cash and (ii) $1.4 million of borrowings under the Company's floor
plan financing arrangement with GMAC to purchase new and used truck and parts
inventory. The Company also agreed to pay the principal of Denver Peterbilt,
Inc. additional amounts based on future sales of new Peterbilt trucks at the
Colorado locations. The Company paid the principal of Denver Peterbilt, Inc.
$2.0 million in March 1999 satisfying all terms of the agreement.

COMPETITION

     There is, and will continue to be, significant competition both within our
current markets and in the new markets which we may enter. We anticipate that
competition between us and other dealers will continue to increase in both our
current markets and on a national level, based on:

     o   the accessibility of dealership locations;

     o   the number of dealership locations;

     o   price, value, quality and design of the products sold; and

     o   attention to customer service (including technical service).

     Our heavy-duty truck products compete with Class 8 and Class 7 trucks made
by other manufacturers and sold through competing independent and factory-owned
truck dealerships, including trucks manufactured by Navistar, Mack,
Freightliner, Kenworth, Volvo, Ford Motor Company, Western Star Truck Holdings,
Ltd., and other manufacturers. Kenworth heavy-duty trucks, which are distributed
through a different, competing dealer network, are also manufactured by PACCAR,
Peterbilt's parent company. Our construction equipment products compete with
construction equipment manufactured by Case, Caterpillar and Komatsu, as well as
other manufacturers. We believe that we are competitive in all of the dealer
categories identified above, and that we are able to compete with
manufacturer-dealers, independent dealers and wholesalers, rental service
companies and industrial auctioneers in distributing our products on the basis
of overall product quality and reputation; "Rush" name recognition and
reputation for reliability; and our ability to provide comprehensive full parts
and service support, as well as financing, insurance and other customer
services.

     DEALERSHIP AGREEMENTS

     Peterbilt. We have entered into non-exclusive dealership agreements with
Peterbilt which authorize us to act as a dealer of Peterbilt heavy-duty trucks.
Our areas of responsibility currently encompass 36 locations in the states of
California, Colorado, Texas, Oklahoma, Louisiana, Arizona and New Mexico. These
dealership agreements have current terms expiring between March 2000 and
December 2002 and impose certain operational obligations and financial
requirements upon us and our dealerships. These agreements are terminable by
Peterbilt upon a change of control of the Company, as such term is described in
each agreement, and grant Peterbilt certain rights of first refusal relating to
any sale or transfer by us of our dealership locations or if certain Rush family
members desire to sell more than 100,000 shares of our voting common stock
within a 12 month period to anyone other than family members or certain other
specified persons. Any termination or non-renewal of these dealership agreements
by Peterbilt must follow certain guidelines established by both state and
federal legislation designed to protect dealers, such as us, from arbitrary
termination or non-renewal of franchise agreements. The Automobile Dealers Day
in Court Act and other similar state laws provide that the



                                       22
<PAGE>   23


termination or non-renewal of a dealership agreement must be done in "good
faith" and upon a showing of "good cause" by the manufacturer for such
termination or non-renewal, as such terms have been defined by statute and case
law.

     John Deere. We have entered into non-exclusive dealership agreements with
John Deere which authorize us to act as a dealer of John Deere construction,
utility and forestry equipment. These John Deere dealership agreements have no
specified term or duration. Our current areas of responsibility for the sale of
John Deere construction equipment encompass seven locations in the states of
Texas and Michigan. The John Deere dealership agreements impose operational
obligations and financial requirements upon us and our dealerships. Like the
dealership agreements with Peterbilt, the dealership agreements with John Deere
are terminable upon change of control, grant certain rights of first refusal and
impose certain financial requirements.

     Other Truck Suppliers. In addition to our truck dealership agreements with
Peterbilt, we are also an authorized dealer for Volvo at our Rush Truck Centers
in Oklahoma City and Tulsa, Oklahoma, and have non-exclusive dealership
agreements with GMC for the sale of GMC medium-duty trucks at our Rush Truck
Centers in San Antonio, Texas, and Oklahoma City and Tulsa, Oklahoma. Sales of
Volvo and GMC trucks accounted for approximately 1.0% of our total revenues for
1999. The Volvo dealership agreement is effective through March 31, 2000 and is
renewable annually unless terminated by Volvo as a result of a material breach
of the agreement by us. The GMC dealership agreement is effective through
October 31, 2000. Both the GMC and Volvo agreements impose operating
requirements upon us and require consent from the affected supplier for sale or
transfer of either such agreement.

     Other Construction Equipment Suppliers. In addition to John Deere, we are
an authorized dealer for suppliers of other construction equipment. The terms of
such arrangements vary, but most of these dealership agreements contain
termination provisions allowing the supplier to terminate the agreement after a
specified notice period (usually 180 days).

     FLOOR PLAN FINANCING

     Heavy-Duty Trucks. We finance substantially all of our new truck inventory
and 75% of the loan value of our used truck inventory, under a floor plan
arrangement with GMAC. As of December 31, 1999, we had approximately $104.5
million outstanding under our GMAC floor plan arrangement. Our GMAC floor plan
facility has no expiration date and generally is renegotiated annually. The
current interest rate is the prime rate less one-half percent.

     Construction Equipment. We finance substantially all our new construction
equipment inventory under floor plan facilities with John Deere and with
Associates. Our John Deere facility expires September 2000 and the current
interest rate is the prime rate less three-quarters of one percent. Our
Associates facility expires September 2000 and the current interest rate is the
prime rate less three-quarters of one percent. As of December 31, 1999, we had
$36.3 million and $10.1 million, respectively, outstanding under the floor plan
arrangements with John Deere and Associates. See "Management's Discussion and
Analysis -- Liquidity and Capital Resources."

SEASONALITY

    The Company's heavy-duty truck business is moderately seasonal. Seasonal
effects on new truck sales related to the seasonal purchasing patterns of any
single customer type are mitigated by the Company's diverse customer base,
including small and large fleets, governments, corporations and owner operators.
However, trucks and parts and service operations historically have experienced
higher volumes of sales in the third and fourth quarters. The Company has
historically received benefits from volume purchases and meeting vendor sales
targets in the form of cash rebates, which are typically recognized when
received. Approximately 40% of such rebates are typically received in the fourth
quarter, resulting in a seasonal increase in gross profit.

     Seasonal effects in the construction equipment business are primarily
driven by the weather. Seasonal effects on construction equipment sales related
to the seasonal purchasing patterns of any single customer type are mitigated by
the Company's diverse customer base that includes contractors, for both
residential and commercial construction, utility companies, federal, state and
local government agencies, and various petrochemical, industrial and material
supply type businesses that require construction equipment in their daily
operations.

BACKLOG

     At December 31, 1999 and 1998, the Company's backlog of truck orders was
approximately $180.0 million. The Company includes in backlog only confirmed
orders. It takes between 60 days and six months for the Company to receive
delivery from PACCAR once an order is placed. The Company expects to fill at
least 90% of these orders by the end of 2000. The Company sells approximately
75% of its new heavy-duty trucks by customer special order, with the remainder
sold out of inventory. Included in the Company's backlog as of December 31, 1999
are orders from a number of the Company's major fleet customers.


ENVIRONMENTAL STANDARDS AND OTHER GOVERNMENTAL REGULATIONS

     Our operations are subject to numerous federal, state and local laws and
regulations, including laws and regulations designed to protect the environment
and to regulate the discharge of materials into the environment, primarily
relating to our service operations.

PRODUCT WARRANTIES

     Both Peterbilt and John Deere provide the retail purchasers of their
products with a limited warranty against defects in materials and workmanship,
excluding certain specified components which are separately warranted by the
suppliers of such components. We do not undertake to provide any warranty to our
customers.

     We generally sell our used trucks and construction equipment "as is" and
without manufacturer's warranty, although manufacturers sometimes will provide a
limited warranty on



                                       24
<PAGE>   25


their used products if they have been properly reconditioned prior to resale or
if the manufacturer's warranty on such product is transferable and has not yet
expired. We do not undertake to provide any warranty to our used truck or
construction equipment customers.

     TRADEMARKS

     The Peterbilt, John Deere, Volvo and GMC trademarks and trade names, which
are used in connection with our marketing and sales efforts, are subject to a
limited license by us from each of the respective manufacturers. These names are
recognized internationally and are important in the marketing of our products.
Each licensor engages in a continuous program of trademark and trade name
protection in its marketing areas. We hold a registered trademark with the U. S.
Patent and Trademark Office for the name "Rush."

     EMPLOYEES

     At December 31, 1999, we employed approximately 1,704 people. We have no
contracts or collective bargaining agreements with labor unions and have never
experienced work stoppages. We consider our relations with our employees to be
good.

ITEM 2.  PROPERTIES

    See PROPERTIES section in ITEM 1 on page 11 hereof.

ITEM 3.  LEGAL PROCEEDINGS

     From time to time, we are involved in certain litigation arising out of our
operations in the ordinary course of business. We maintain liability insurance,
including product liability coverage, in amounts deemed adequate by management.
To date, aggregate costs to us for claims, including product liability actions,
have not been material. However, an uninsured or partially insured claim, or
claim for which indemnification is not available, could have a material adverse
effect on our financial condition. We believe that there are no claims or
litigation pending the outcome of which could have a material adverse effect on
our financial position or results of operations. However, due to the inherent
uncertainty of litigation, there can be no assurance that the resolution of any
particular claim or proceeding would not have a material adverse effect on our
results of operations for the fiscal period in which such resolution occurred.

ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

     No matters were submitted to a vote of the Company's shareholders during
the fourth quarter of the fiscal year ended December 31, 1999.

(1)  For all periods presented prior to the Company's public offering on June 7,
     1996, the Company was an S corporation and was not generally subject to
     corporate income taxes. The pro forma income tax provision has been
     computed as if the Company were subject to corporate income taxes for all
     periods presented based on the tax laws in effect during the respective
     periods. See Note 13 to the Consolidated Financial Statements.

(2)  Pro forma basic and diluted income from continuing operations per share was
     computed by dividing pro forma income from continuing operations by the
     weighted average number of common shares outstanding, as adjusted for the
     stock split of the Common Stock and giving pro forma effect for the
     issuance of 547,400 shares of Common Stock, at an initial public offering
     price of $12.00 per share, to repay the line-of-credit borrowings made to
     fund the approximately $6.0 million distribution to the Company's sole
     shareholder of the undistributed taxable S corporation earnings. See Note 1
     to the Consolidated Financial Statements.

     We are a full-service, integrated retailer of premium transportation and
construction equipment and related services. As the leading supplier of
Peterbilt trucks, we accounted for approximately 20.7% of all new Peterbilt
trucks sold in the United States in 1999. In 1997, we acquired our first John
Deere construction equipment dealership in Houston, Texas and have grown to
become a major supplier of John Deere construction equipment. Through our
strategically located networks of Rush Truck Centers and Rush Equipment Centers,
we provide one-stop service for the needs of our customers, including retail
sales of new and used transportation and construction equipment, as well as
after-market parts sales, service and repair facilities and financing,
leasing/rental, and insurance services.

     Our Rush Truck Centers are principally located in high traffic areas along
the southwestern corridor of the United States. Our Rush Equipment Centers are
located in two of the top six construction equipment sales markets in the United
States -- Texas and Michigan. We provide leasing and rental services through our
Rush Leasing and Rental Division at our one-stop Rush Truck Centers and Rush
Equipment Centers. Retail financing of trucks and construction equipment, as
well as a full line of insurance products, are arranged through our Rush
Financial and Insurance Division. Our Rush Retail Division has developed the
one-stop shopping strategy for our farm and ranch supply business.

     Our business strategy, based upon providing the customer with competitively
priced products supported with timely and reliable service, has enabled us since
1996 to increase revenues at a compounded annual growth rate of 33.0% and to
increase earnings at a compounded annual growth rate of 37.5%. We intend to
continue to implement our business strategy, reinforce customer loyalty and
remain a market leader by continuing to develop our Rush Truck Centers and Rush
Equipment Centers as we extend our geographic focus through strategic
acquisitions of new locations and expansions of our existing facilities.

     All of our business operations are currently conducted through five
separate divisions: the Rush Truck Center Division, the Rush Equipment Center
Division, the Rush Leasing and Rental Division, the Rush Financial and Insurance
Division and the Rush Retail Division.

     Rush Truck Center Division. Since commencing operations as a Peterbilt
heavy-duty truck dealer over 34 years ago, we have grown to operate Rush Truck
Centers at 36 locations which primarily sell Peterbilt Class 8 heavy-duty trucks
in the states of Texas, Colorado, Oklahoma, California, Louisiana, Arizona and
New Mexico. Our Rush Truck Centers are strategically located to take advantage
of increased cross-border traffic between the United States and Mexico resulting
from implementation of NAFTA in 1994. During 1999, our Rush Truck Center
Division accounted for approximately $662.5 million, or approximately 82.0%, of
our total revenues.

     Rush Equipment Center Division. Since commencing operations as a John Deere
dealer in 1997, we have grown to operate nine Rush Equipment Centers located in
Texas and Michigan. We provide a full line of construction equipment for light
to medium sized applications, with our primary products including John Deere
backhoe loaders, hydraulic excavators, crawler dozers and four wheel drive
loaders. During 1999, our Rush Equipment Center Division accounted for
approximately $82.7 million, or approximately 10.2%, of our total revenues.

     Rush Leasing and Rental Division. We provide a broad line of product
selections for lease or rent, including Class 8, Class 7 and Class 6 Peterbilt
trucks, a full array of John Deere construction equipment products, including a
variety of construction equipment trailers and heavy-duty cranes. Our lease and
rental fleets are offered primarily through our Rush Truck Centers and Rush
Equipment Centers on a daily, monthly or long-term basis. During 1999, our Rush
Leasing and Rental Division accounted for approximately $31.0 million, or
approximately 3.8%, of our total revenues.



                                       30

     Rush Financial and Insurance Division. We offer third-party financing to
assist customers in purchasing a new or used truck or piece of construction
equipment. Additionally, we sell a complete line of property and casualty
insurance, including collision and liability insurance on trucks, cargo
insurance, standard automobile liability coverages, and life insurance. During
1999, our Rush Financial and Insurance Division accounted for approximately
$13.6 million, or approximately 1.7%, of our total revenues.

     Rush Retail Division. During 1998, we created the Rush Retail Division in
connection with our acquisition of D&D Farm and Ranch Supermarket, Inc. ("D&D").
D&D is a one-stop shopping center for farm and ranch supplies, serving the
greater San Antonio, Texas area. We anticipate opening a second D&D store in
Houston, Texas in 2000. During 1999, our Rush Retail Division accounted for
approximately $18.6 million, or approximately 2.3%, of our total revenues.

FISCAL YEAR ENDED DECEMBER 31, 1999 COMPARED WITH FISCAL YEAR ENDED DECEMBER 31,
1998.

Revenues

    Revenues increased by approximately $195.6 million, or 31.9%, from $612.8
million to $808.4 million from 1998 to 1999. This increase was attributable to
gains achieved from each of the Company's revenue categories, primarily as a
result of improved operations, increased market demand, and revenues generated
from acquisitions and new store openings.

    Sales of new and used trucks increased by approximately $131.8 million, or
31.2%, from $422.8 million to $554.6 million from 1998 to 1999. Unit sales of
new and used trucks increased by 24.4% and 3.3%, respectively. The increase in
new truck sales was mainly due to increasing fleet sales, acquisitions and an
overall strong new truck market in 1999. The moderate growth rate in used truck
sales is a result of a shortage of desirable used truck inventory during 1999
caused by fewer used truck trade-ins. The average selling price of new trucks
increased by 9.6% while used truck average selling prices increased by 5.9%. New
truck and used truck prices increased due to product mix and increased market
demand.

    Parts and service sales increased by approximately $22.5 million, or 20.8%,
from $108.0 million to $130.5 million from 1998 to 1999, with the inclusion of a
full year of operations in the Rush equipment center in western Michigan,
compared to only four months of operations in western Michigan in 1998, and the
1999 additions of the equipment center in eastern Michigan, and the truck
centers in Arizona, New Mexico and California accounting for approximately $13.4
million or 60.4% of the increase and the remainder being attributed to growth at
existing locations.

    Sales of new and used construction equipment increased approximately $26.6
million or 75.1%, from $35.4 million to $62.0 million from 1998 to 1999. The
increase is due to the construction equipment segment only having four months of
western Michigan operations in 1998 and the addition of the eastern Michigan
construction equipment dealership in September of 1999. New and used equipment
unit sales were 247 and 120, respectively, for the year ended 1998 compared to
646 and 337 new and used units, respectively, in 1999.

    Lease and rental revenues increased by approximately $6.8 million, or 36.6%,
from $18.6 million to $25.4 million from 1998 to 1999, primarily due to the
inclusion of a full year of operations at the Rush equipment center in western
Michigan and the acquisition of the equipment center in eastern Michigan, and
the remainder being attributed to growth at existing locations.

    Finance and insurance revenues increased by approximately $2.2 million, or
19.3%, from $11.4 million to $13.6 million from 1998 to 1999. The growth
resulted from increased truck sales coupled with lower borrowing costs during
1999 compared to 1998. Finance and insurance revenues have limited direct costs
and, therefore, contribute a disproportionate share of operating profits.



                                       32
<PAGE>   33


     Retail sales revenue, generated by D&D, increased $4.7 million or 33.8%
from 1998 to 1999. The growth in 1999 was favorably impacted as the results for
1998 reflect only 10 months of operations due to the acquisition of D&D in
February 1998.

     Other income increased approximately $1.0 million or 37.0%, from $2.7
million to $3.7 million from 1998 to 1999, primarily due to the increase in
truck sales by the leasing operations.

Gross Profit

     Gross profit increased by approximately $30.3 million, or 29.0%, from
$104.5 million to $134.8 million from 1998 to 1999. Approximately $10.3 million
or 34.0% of the increase is attributable to the inclusion in the results of
operations of retail locations either acquired in 1999 or conducting their first
full year of operations in 1999. The remaining gross profit increase of $20.0
million or 66.0% is attributable to growth at existing locations. Gross profit
as a percentage of sales decreased from 17.1% during 1998 to 16.7% during 1999.
The decrease in gross margins was due to a slight decrease in gross margins on
the sale of new trucks due to increased fleet sales in 1999, and decreases in
the higher margin parts and service, and finance and insurance sales, as a
percentage of total sales, from 1998 to 1999.

Selling, General and Administrative

     Selling, general and administrative expenses increased by approximately
$17.7 million, or 23.4%, from $75.8 million to $93.5 million from 1998 to 1999.
The increase includes $8.7 million or 49.2%, attributable to the operations of
new truck and equipment locations either acquired in 1999 or conducting their
first full year of operations in 1999. The remaining increase resulted primarily
from an increase in salaries and sales commissions due to increases in revenues
and gross profit in 1999 compared to 1998. Selling, general and administrative
expenses as a percent of revenue were 12.4% and 11.6% in 1998 and 1999,
respectively.

Interest Expense, Net

     Net interest expense increased by approximately $2.3 million, or 39.0%,
from approximately $5.9 million to $8.2 million, from 1998 to 1999. Interest
expense increased primarily as a result of increased levels of indebtedness due
to higher floor plan liability levels and the debt financing of certain real
property purchased or improved during 1999.

Income Before Income Taxes

     Income before income taxes increased by $8.9 million, or 49.4%, from $18.0
million to $26.9 million, from 1998 to 1999, as a result of the factors
described above.

<PAGE>   34


Income Taxes

     Income taxes increased by $3.6 million, or 50.0%, from $7.2 million to
$10.8 million, from 1998 to 1999. The Company has provided for taxes at the 40%

1997.

Revenues

     Revenues increased by approximately $213.4 million, or 53.4%, from $399.4
million to $612.8 million from 1997 to 1998. This increase was attributable to
gains achieved from each of the Company's revenue categories, primarily as a
result of improved operations, increased market demand, and revenues generated
from acquisitions and new store openings.

     Sales of new and used trucks increased by approximately $132.3 million, or
45.5%, from $290.5 million to $422.8 million from 1997 to 1998. Unit sales of
new and used trucks increased by 41.9% and 6.9%, respectively. The large
increase in new truck sales was mainly due to increasing fleet sales and an
overall strong new truck market in 1998. The moderate growth rate in used truck
sales is a result of a shortage of desirable used truck inventory during 1998
caused by fewer used truck trade-ins. The average selling price of new trucks
increased by 5.9% while used truck average selling prices increased by 13.8%.
New truck and used truck prices increased due to product mix and increased
market demand.

     Parts and service sales increased by approximately $29.3 million, or 37.2%,
from $78.7 million to $108.0 million from 1997 to 1998, with the inclusion of a
full year of operations in Colorado, Pharr and at the Rush equipment center in
Houston, Texas, and the 1998 additions of the Rush retail center and the
equipment center in Michigan accounting for approximately $14.4 million or 49.1%
of the increase and the remainder being attributed to growth at existing
locations.

     Sales of new and used construction equipment increased approximately $27.9
million or 372%, from $7.5 million to $35.4 million from 1997 to 1998. The
increase is due to the construction equipment segment only having three months
of operations in 1997 and the addition of the Michigan construction equipment
dealership in September of 1998. New and used equipment unit sales were 247 and
120, respectively, for the year ended 1998.

     Lease and rental revenues increased by approximately $3.8 million, or
25.7%, from $14.8 million to $18.6 million from 1997 to 1998, with the inclusion
of a full year of operations at the Rush equipment center in Houston, Texas and
the acquisition of the equipment center in Michigan accounting for approximately
$2.4 million or 63.2% of the increase, and the remainder being attributed to
growth at existing locations.



                                       34
<PAGE>   35


     Finance and insurance revenues increased by approximately $5.4 million, or
90%, from $6.0 million to $11.4 million from 1997 to 1998. The growth resulted
from increased truck sales coupled with lower borrowing costs during 1998
compared to 1997. Finance and insurance revenues have limited direct costs and,
therefore, contribute a disproportionate share of operating profits.

     Retail sales revenue totaled $13.9 million during 1998 and was generated
entirely by D&D in its first year with the Company.

     Other income increased approximately $0.8 million or 42.1%, from $1.9
million to $2.7 million from 1997 to 1998, primarily due to the increase in
truck sales by the leasing operations.

Gross Profit

     Gross profit increased by approximately $39.7 million, or 61.3%, from $64.8
million to $104.5 million from 1997 to 1998. Approximately $17.4 million or
43.8% of the increase is attributable to the operations of new truck, equipment
and retail locations previously described, either acquired in 1998 or conducting
their first full year of operations in 1998. The remaining gross profit increase
of $22.3 million or 56.2% is attributable to growth at existing locations. Gross
profit as a percentage of sales increased from 16.2% during 1997 to 17.1% during
1998. The increase in gross margins was due to a .22% increase in gross margins
on the sale of new and used trucks, a 1% increase in gross margins on heavy-duty
truck parts, service and body shop sales, and the inclusion of a full year of
construction equipment store operations which had a gross margin of 23.4% on
approximately $51.3 million in revenue in 1998 compared to a gross margin of
20.6% on approximately $10.2 million in sales in 1997.

Selling, General and Administrative

     Selling, general and administrative expenses increased by approximately
$25.2 million, or 49.8%, from $50.6 million to $75.8 million from 1997 to 1998.
The increase includes $12.9 million or 51.2%, attributable to the operations of
new truck, equipment and retail locations previously described, either acquired
in 1998 or conducting their first full year of operations in 1998. The remaining
increase resulted from an increase in salaries and sales commissions due to
increases in revenues and gross profit in 1998 compared to 1997. Selling,
general and administrative expenses as a percent of revenue were 12.7% and 12.4%
in 1997 and 1998, respectively.

Interest Expense, Net

     Net interest expense increased by approximately $3.4 million, or 136.0%,
from approximately $2.5 million to $5.9 million, from 1997 to 1998. Interest
expense increased primarily as a result of increased levels of indebtedness due
to higher floor plan liability levels and the refinancing of certain real
property owned by the Company during the fourth quarter of 1997.

Income Before Income Taxes

     Income from continuing operations increased by $9.3 million, or 106.9%,
from $8.7 million to $18.0 million, from 1997 to 1998, as a result of the
factors described above.

Income Taxes

     Income taxes increased by $3.9 million, or 118.2%, from $3.3 million to
$7.2 million, from 1997 to 1998. The Company has provided for taxes at the 40%
effective rate.

LIQUIDITY AND CAPITAL RESOURCES

     The Company's short-term cash needs are primarily for working capital,
including inventory requirements, expansion of existing facilities and
acquisitions of new facilities. These short-term cash needs have historically
been financed with retention of profits and borrowings under credit facilities
available to the Company.

     At December 31, 1999, the Company had working capital of approximately $2.8
million, including $20.0 million in cash, $29.8 million in accounts receivable,
$173.6 million in inventories, and $0.7 million in prepaid expenses and other
offset by $150.9 million outstanding under floor plan notes payable, $8.5
million in current maturities of long-term debt, $11.0 million in advances
outstanding under lines of credit, $9.7 million of trade accounts payable, $20.5
million in accrued expenses, and $20.7 million in a note payable to shareholder.
The aggregate maximum borrowing limits under working capital lines of credit
with its primary truck lender are approximately $12.0 million. The Company has a
separate unsecured line-of-credit agreement with a financial institution that
provides for an aggregate maximum borrowing of $10,000,000.

     The Company's floor plan agreements with its primary truck lender limit the
aggregate amount of borrowings based on the number of new and used trucks. As of
December 31, 1999, the Company's floor plan arrangements permit the financing of
up to 1,777 new trucks and 710 used trucks, and the availability for new and
used trucks is 703 and 321, respectively. The Company's floor plan agreement
with its primary construction equipment lender is based on the book value of the
Company's construction equipment inventory. As of December 31, 1999, the
aggregate amount of borrowing capacity was $25 million, with approximately $10.1
million outstanding. Additional amounts are available under the Company's John
Deere dealership and credit agreements. At December 31, 1999, approximately
$36.3 million was outstanding pursuant to the John Deere agreements.

     During 1999, the Company used $27.8 million of net cash in operating
activities. Net income of $16.2 million and increases in depreciation and
amortization, deferred income tax expense and trade accounts payable of $8.4
million, $2.6 million and $2.8 million respectively, were more than offset by
increases in accounts receivable and inventories of $10.2 million and $46.7
million respectively, a decrease in accrued expenses of $0.5 million, and the
gain on sale of property and equipment of $0.2 million.



                                       36
<PAGE>   37


     During 1999, the Company used $83.3 million of net cash in investing
activities, including expenditures of $21.8 million related to business
acquisitions, and $60.3 million that was related to the expansion of various
facilities and the purchase of units placed in the Company's truck leasing
fleet. These expenditures have resulted in a net increase of $49.0 million in
property and equipment from 1998 to 1999.

     Net cash provided by financing activities in 1999 amounted to $108.6
million. Cash flows from financing activities included proceeds of $58.4 million
from notes payable due to the financing of expansion projects and the purchase
of units placed in the Company's truck leasing fleet, a net increase of $49.5
million in floor plan notes payable, draws on lines of credit of $10.9 million,
and principal payments on notes payable of $10.2 million.

     During 1999, the Company arranged customer financing for approximately
45.9% of its total new and used truck sales, and derived approximately 64% and
36% of its finance revenues from the sale of new and used trucks, respectively.
The Company's new and used truck financing is typically provided through
Associates and PACCAR Financial. The Company financed approximately $254.4
million of new and used truck purchases in 1999. The Company's contracts with
Associates and PACCAR Financial provide for payment to the Company of all
finance charges in excess of a negotiated discount rate within 30 days of the
date of financing, with such payments subject to offsets resulting from the
early pay-off or defaults under installment contracts previously sold to
Associates and PACCAR Financial by the Company. The Company's agreements with
Associates and PACCAR Financial limit the aggregate liability of the Company for
repossession losses resulting from defaults under the installment contracts sold
to Associates and PACCAR Financial to $500,000 and $200,000 per year,
respectively.

     In addition, through The CIT Group, Associates, John Deere Credit and
others, the Company arranged customer financing for approximately $29.2 million,
or approximately 47.1%, of our total new and used construction equipment sales
in 1999. Approximately 70% of these construction equipment financings related to
new construction equipment sales and the remainder related to used construction
equipment sales. Generally, construction equipment financings are memorialized
through the use of installment or lease contracts, which are secured by the
construction equipment financed, and generally require a down payment of 0% to
10% of the value of the financed piece of construction equipment, with the
remaining balance being financed over a three-to five-year period. The Company
experiences no repossession loss on construction equipment financings because
such financings are sold to third parties without recourse.


     Substantially all of the Company's truck purchases from PACCAR are made on
terms requiring payment within 15 days or less from the date of shipment of the
trucks from the factory. The Company finances all, or substantially all, of the
purchase price of its new truck inventory, and 75% of the loan value of its used
truck inventory, under a floor plan arrangement with GMAC under which GMAC pays
PACCAR directly with respect to new trucks. The Company makes monthly interest
payments on the amount financed but is not required to commence loan principal
repayments prior to sale on new vehicles to GMAC for a period of 12



                                       37
<PAGE>   38


months and for used vehicles for a period of three months. At December 31, 1999,
the Company had approximately $104.2 million outstanding under its floor plan
financing arrangement with GMAC. GMAC permits the Company to earn, for up to
50.0% of the amount borrowed under its floor plan financing arrangement with
GMAC, interest at the prime rate, less three-quarters of a percent, on overnight
funds deposited by the Company with GMAC.

     Substantially all of the Company's new equipment purchases are financed by
John Deere and Associates Commercial Corporation. The Company finances all, or
substantially all, of the purchase price of its new equipment inventory, under
its floor plan facilities. The agreement with John Deere provides interest free
financing for four months after which time the amount financed is required to be
paid in full, or an immediate 2.25% discount with payment due in 30 days. When
the equipment is sold prior to the expiration of the four month period, the
Company is required to repay the principal within approximately 10 days of the
sale. Should the equipment financed by John Deere not be sold within the four
month period, it is transferred to the Associates Commercial Corporation. floor
plan arrangement. The Company makes principal payments to Associates Commercial
Corporation, for sold inventory, on the 15th day of each month . Used and rental
equipment, to a maximum of book value, is financed under a floor plan
arrangement with Associates Commercial Corporation. The Company makes monthly
interest payments on the amount financed and is required to commence loan
principal repayments on rental equipment as book value reduces. Principal
payments, for sold used equipment, are made the 15th day of each month following
the sale. The loans are collateralized by a lien on the equipment. The Company's
floor plan agreements limit the aggregate amount of borrowings based on the book
value of new and used equipment units. As of December 31, 1999, the Company's
floor plan arrangement with Associates Commercial Corporation permits the
financing of up to $25 million in construction equipment. At December 31, 1999,
the Company had $36.3 million and $10.1 million outstanding under its floor plan
financing arrangements with John Deere and Associates Commercial Corporation,
respectively.

Seasonality

         The Company's heavy-duty truck business is moderately seasonal.
Seasonal effects on new truck sales related to the seasonal purchasing patterns
of any single customer type are mitigated by the Company's diverse customer
base, which includes small and large fleets, governments, corporations and owner
operators. However, truck, parts and service operations historically have
experienced higher volumes of sales in the second and third quarters. The
Company has historically received benefits from volume purchases and meeting
vendor sales targets in the form of cash rebates, which are typically recognized
when received. Approximately 40% of such rebates are typically received in the
fourth quarter, resulting in a seasonal increase in gross profit.

    Seasonal effects in the construction equipment business are primarily driven
by the weather. Seasonal effects on construction equipment sales related to the
seasonal purchasing patterns of any single customer type are mitigated by the
Company's diverse customer base that includes contractors, for both residential
and commercial construction, utility companies, federal, state and local
government agencies, and various petrochemical, industrial and material supply
type businesses that require construction equipment in their daily operations.




                                       38
<PAGE>   39


Cyclicality

     The Company's business, as well as the entire retail heavy-duty truck
industry, is dependent on a number of factors relating to general economic
conditions, including fuel prices, interest rate fluctuations, economic
recessions and customer business cycles. In addition, unit sales of new trucks
have historically been subject to substantial cyclical variation based on such
general economic conditions. According to R.L. Polk, industry-wide domestic
retail sales of heavy-duty trucks exceeded 200,000 units for only the third
time, recording approximately 247,000 new truck registrations in 1999. The
industry forecasts a decrease ranging from 15% to 20% in heavy-duty new truck
sales in 2000. Although the Company believes that its geographic expansion and
diversification into truck-related services, including financial services,
leasing, rentals and service and parts, will reduce the overall impact to the
Company resulting from general economic conditions affecting heavy-duty truck
sales, the Company's operations may be materially and adversely affected by any
continuation or renewal of general downward economic pressures or adverse
cyclical trends.


ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

         Market risk represents the risk of loss that may impact the financial
position, results of operations, or cash flows of the Company due to adverse
changes in financial market prices, including interest rate risk, and other
relevant market rate or price risks.

         The Company is exposed to some market risk through interest rates,
related to its floor plan borrowing arrangements, variable rate debt and
discount rates related to finance sales. Floor plan borrowings are based on the
prime rate of interest and are used to meet working capital needs. As of
December 31, 1999, the Company had floor plan borrowings of approximately
$150,862,000. Assuming an increase in the prime rate of interest of 100 basis
points, future cash flows would be effected by $1,508,000. The interest rate
variability on all other debt would not have a material adverse effect on the
Company's financial statements. The Company provides all customer financing
opportunities to various finance providers. The Company receives all finance
charges, in excess of a negotiated discount rate, from the finance providers
within 30 days. The negotiated discount rate is variable, thus subject to
interest rate fluctuations. This interest rate risk is mitigated by the
Company's ability to pass discount rate increases to customers through higher
financing rates.

1998 and 1999, and the related consolidated statements of income, shareholders'
equity and cash flows for each of the three years in the period ended December
31, 1999. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States. 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 Rush Enterprises,
Inc., and subsidiaries as of December 31, 1998 and 1999, and the results of
their operations and their cash flows for each of the three years in the period

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS



1. ORGANIZATION AND OPERATIONS:

Rush Enterprises, Inc. (the Company), was incorporated in June 1996 under the
laws of the State of Texas. The Company, founded in 1965, now operates a
Heavy-duty Truck segment and a Construction Equipment segment. The Heavy-duty
Truck segment operates a regional network of 36 truck centers that provide an
integrated one-stop source for the trucking needs of its customers, including
retail sales of new Peterbilt and used heavy-duty trucks; parts, service and
body shop facilities; and financial services, including assisting in the
financing of new and used truck purchases, insurance products and truck leasing
and rentals. The Company's truck centers are located in areas on or near major
highways in Texas, California, Colorado, Oklahoma, Louisiana, Arizona and New
Mexico. The Construction Equipment segment, formed during 1997, operates a
network of seven John Deere equipment centers in Texas and Michigan. Dealership
operations include the retail sale of new and used equipment, after-market parts
and service facilities, equipment rentals, and the financing of new and used
equipment (see note 17).

In March 1998, the Company developed a new retail division, Rush Retail Centers,
and acquired all of the issued and outstanding capital stock of D & D Farm and
Ranch Supermarket Inc. Rush Retail Centers' primary line of business is the
retail sale of farm and ranch supplies including fencing, horse and cattle
trailers, veterinarian supplies and western wear (see note 15).

In September 1998, the Company acquired all of the assets and assumed certain
liabilities of Klooster Equipment, Inc. and began operations of Rush Equipment
Centers Michigan. Klooster Equipment Inc.'s primary line of business is the sale
and rental of new John Deere and used construction equipment, parts and service
(see note 15).

In September 1999, the Company acquired substantially all the assets of Calvert
Sales, Inc., (Calvert), a John Deere construction equipment dealership. The
acquisition encompasses 13 counties in eastern Michigan, including two
full-service dealerships located in the Detroit and Flint areas. Calvert's
primary line of business is the sale and rental of new John Deere and used
construction equipment, parts and service (see note 15).

In October 1999, the Company purchased substantially all the assets of Southwest
Peterbilt, Inc., Southwest Truck Center, Inc., and New Mexico Peterbilt, Inc.,
(Southwest) a Peterbilt truck dealer, which consisted of five dealership
locations in Arizona and New Mexico. Southwest's primary line of business is the
sale of new Peterbilt and used heavy-duty trucks, parts and service (see note
15).

In December 1999, the Company purchased substantially all the assets of Norm
Pressley's Truck Center, (Pressley), which consisted of three dealership
locations in San Diego, Escondido and El Centro, California. Pressley's primary
line of business is the sale of new Peterbilt and used heavy-duty trucks, parts,
leasing and service (see note 15).

As part of the Company's corporate reorganization in connection with its initial
public offering (Offering) in June 1996, the Company acquired, as a wholly owned
subsidiary, a managing general agent (the MGA) to manage all of the operations
of Associated Acceptance, Inc. (AA). W. Marvin Rush, the sole shareholder of AA,
is prohibited from the sale or transfer of the capital stock of AA under the MGA
agreement, except as designated by the Company. Therefore, the financial
position and operations of AA have been included as part of the Company's
consolidated financial position and results of operations for all periods
presented.

All significant interdivision and intercompany accounts and transactions have
been eliminated in consolidation. Certain prior period balances have been
reclassified for comparative purposes.

2. SIGNIFICANT ACCOUNTING POLICIES:


                                       46
<PAGE>   47

Estimates in Financial Statements

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 may differ from those estimates.

Inventories

Inventories are stated at the lower of cost or market value. Cost is determined
by specific identification for new and used truck and construction equipment
inventory and by utilizing the first-in, first-out methods for tires, parts and
accessories.

Property and Equipment

Property and equipment are being depreciated over their estimated useful lives.
Leasehold improvements are amortized over the useful life of the improvement, or
the term of the lease, whichever is shorter. Both the straight-line and double
declining-balance methods of depreciation are used. The Company capitalizes
interest on borrowings during the active construction period of major capital
projects. Capitalized interest is added to the cost of underlying assets and is
amortized over the estimated useful life of such assets. During 1999, the
Company capitalized approximately $165,000 in connection with various capital
projects. The cost, accumulated depreciation and amortization and estimated
useful lives are summarized as follows (in thousands):

Allowance for Doubtful Receivables
   and Repossession Losses

The Company provides an allowance for doubtful receivables and repossession
losses after considering historical loss experience and other factors which
might affect the collectibility of accounts receivable and the ability of
customers to meet their obligations on finance contracts sold by the Company.

Other Assets

Other assets primarily consist of goodwill related to acquisitions of
approximately $15.1 million and $37.0 million, as of December 31, 1998 and 1999,
respectively, and long-term deposits. The goodwill is being amortized on a
straight-line basis over estimated useful lives ranging from 15 to 30 years.
Accumulated amortization of other assets, at December 31, 1998 and 1999, was
approximately $1.1 million and $2.0 million, respectively. Periodically, the
Company assesses the appropriateness of the asset valuations of goodwill and the
related amortization period.


                                       47
<PAGE>   48

Income Taxes

Income taxes are accounted for under the provisions of Statement of Financial
Accounting Standards No. 109, "Accounting for Income Taxes" (SFAS 109). SFAS 109
requires recognition of deferred tax liabilities and assets for the expected
future tax consequences of events that have been included in a company's
financial statements or tax returns. Under this method, deferred tax liabilities
and assets are determined based on the differences between the financial
statement and tax bases of assets and liabilities using currently enacted tax
rates in effect for the years in which the differences are expected to reverse.

Revenue Recognition Policies

Income on the sale of vehicles and construction equipment (collectively, "unit")
is recognized when the seller and customer execute a purchase contract and
delivery has occurred and there are no significant uncertainties related to
financing or collectibility. Finance income related to the sale of a unit is
recognized over the period of the respective finance contract on the effective
interest rate method if the finance contract is retained by the Company. During
1997, 1998 and 1999, no finance contracts were retained for any significant
length of time by the Company but were generally sold, with limited recourse, to
certain finance companies concurrent with the sale of the related unit. Gain or
loss is recognized by the Company upon the sale of such finance contracts to the
finance companies, net of a provision for estimated repossession losses and
early repayment penalties. Lease and rental income is recognized over the period
of the related lease or rental agreement. Parts and services revenue is earned
at the time the Company sells the parts to its customers, or at the time the
Company completes the service work order related to service provided to the
customer's unit. Payments received on pre-paid maintenance plans are deferred as
a component of accrued expenses and recognized as income when the maintenance is
performed. Retail revenue is earned at the time the Company sells the
merchandise to its customer.

Statement of Cash Flows

Cash and cash equivalents generally consist of cash and other money market
instruments. The Company considers any temporary investments that mature in
three months or less when purchased to be cash equivalents for reporting cash
flows.

Noncash activities during the periods indicated were as follows (in thousands):

3.   SUPPLIER AND CUSTOMER CONCENTRATION:

Major Suppliers and Dealership Agreements

The Company has entered into dealership agreements with various companies
(Distributors). These agreements are nonexclusive agreements that allow the
Company to stock, sell at retail and service trucks and products of the
Distributors in the Company's defined market. The agreements allow the Company
to use the Distributor's name, trade symbols and intellectual property and
expire as follows:

<TABLE>
<CAPTION>
 Distributor                           Expiration Dates
 -----------                           ----------------
<S>                                   <C>
  PACCAR                              March 2000 to December  2002
  GMC                                 October 2000
  Volvo                               March 2000
  John Deere                          Indefinite
</TABLE>

These agreements impose a number of restrictions and obligations on the Company,
including restrictions on a change in control of the Company and the maintenance
of certain required levels of working capital. Violation of such restrictions
could result in the loss of the Company's right to purchase the Distributor's
products and use the Distributor's trademarks. As of December 31, 1999, the
Company's management believes it was in compliance with all the restrictions of
its dealership agreements.

The Company purchases most of its new vehicles and parts from PACCAR, the maker
of Peterbilt trucks and parts, at prevailing prices charged to all franchised
dealers. Sales of new Peterbilt trucks accounted for 97 percent and 98 percent
of the Company's new vehicle sales for the years ended December 31, 1998 and
1999, respectively.

The Company purchases most of its new construction equipment and parts from John
Deere at prevailing prices charged to all franchised dealers. Sales of new John
Deere equipment accounted for 88 percent and 91 percent of the Company's new
equipment sales for the years ended December 31, 1998 and 1999, respectively.

Primary Lenders

The Company purchases its new and used truck and construction equipment
inventories with the assistance of floor plan financing programs offered by
various financial institutions and John Deere. The financial institution used
for truck inventory purchases also provides the Company with a line of credit
that allows borrowings of up to $12,000,000 and other variable interest rate
notes. The loan agreement with the financial institution, used for truck
inventory purchases, provides that such agreement may be terminated at the
option of the lender with notice of 120 days.

The loan agreement with the financial institution used primarily for
construction equipment purchases expires in September 2000. Additionally,
financing is provided by John Deere pursuant to the Company's equipment
dealership agreement. Furthermore, the agreements also provide that the
occurrence of certain events will be considered events of default. In the event
that the Company's financing becomes insufficient, or its relationship
terminates with the current primary lenders, the Company would need to obtain
similar financing from other sources. Management believes it can obtain
additional floor plan financing or alternative financing if necessary (see note
6).

Concentrations of Credit Risks

Financial instruments that potentially subject the Company to significant
concentrations of credit risk consist principally of cash and cash equivalents
and accounts receivable.

The Company places its cash and cash equivalents with what it considers to be
quality financial institutions. At December 31, 1999, the Company had deposits
in excess of federal insurance totaling approximately $5.0 million.



                                       49
<PAGE>   50

Concentrations of credit risk with respect to trade receivables are reduced
because a large number of geographically diverse customers make up the Company's
customer base, thus, spreading the trade credit risk. A majority of the
Company's business, however, is concentrated in the United States heavy-duty
trucking and construction equipment markets and related aftermarkets. The
Company controls credit risk through credit approvals and by selling certain
trade receivables without recourse. Related to the Company's finance contracts,
after the finance contract is entered into, the Company generally sells the
contracts to a third party. The finance contracts are sold both with and without
recourse, but the annual amount of recourse losses which can be put to the
Company is contractually limited (see note 14). Historically, bad debt expense
associated with the Company's accounts receivable and finance contracts has not
been significant.

4. ACCOUNTS RECEIVABLE:

The Company's accounts receivable, net, consisted of the following (in
thousands):

6. FLOOR PLAN NOTES PAYABLE AND LINES OF CREDIT:

Floor Plan Notes Payable

Floor plan notes are financing agreements to facilitate the Company's purchase
of new and used trucks and construction equipment. These notes are
collateralized by the inventory purchased and accounts receivable arising from
the sale thereof. The Company's floor plan notes have interest rates at prime
less a percentage rate as determined by the finance provider, as defined in the
agreements. The interest rates applicable to these agreements were 7.75 to 8.0
percent as of December 31, 1999. The amounts borrowed under these agreements are
due when the related truck or construction equipment inventory (collateral) is
sold and the sales proceeds are collected by the Company, or in the case of
construction equipment rentals, when the carrying value of the equipment is
reduced. These lines may be modified, suspended, or terminated by the lender as
described in note 3.

The Company's floor plan agreement with its primary truck lender limits the
borrowing capacity based on the number of new and used trucks that may be
financed. As of December 31, 1999, the aggregate amounts of unit capacity for
new and used trucks are 1,777 and 710, respectively, and the availability for
new and used trucks is 703 and 321, respectively.

The Company's floor plan agreement with its construction equipment lender is
based on the book value of the Company's construction equipment inventory. As of
December 31, 1999, the aggregate amount of borrowing capacity with the Company's
equipment lender was $25 million, with approximately $10.1 million outstanding.
Additional amounts are available under the Company's John Deere dealership and
credit agreements. At December 31, 1999, approximately $36.3 million was
outstanding pursuant to the John Deere agreements.

Amounts of collateral as of December 31, 1999, are as follows (in thousands):

8.   DISCLOSURES ABOUT FAIR VALUE OF
      FINANCIAL INSTRUMENTS:

The following methods and assumptions were used to estimate the fair value of
each class of financial instrument held by the Company:

         Current assets and current liabilities - The carrying value
           approximates fair value due to the short maturity of these items.

         Long-term debt - The fair value of the Company's long-term debt is
           based on secondary market indicators. Since the Company's debt is not
           quoted, estimates are based on each obligation's characteristics,
           including remaining maturities, interest rate, credit rating,
           collateral, amortization schedule and liquidity. The carrying amount
           approximates fair value.

9.   DEFINED CONTRIBUTION PENSION PLANS:

The Company has a defined contribution pension plan (the Rush Plan) which is
available to all Company employees and the employees of certain affiliates. As
of January and July 1st of every year, each employee who has completed six
months of continuous service is entitled to enter the Rush Plan. Participating
employees may contribute from 2 percent to 10 percent of total gross
compensation. The Company, at its discretion, contributed an amount equal to 25
percent of the employees' contributions for those employees with less than five
years of service and contributed an amount equal to 50 percent of the employees'
contributions for those employees with more than 5 years of service. During the
years ended December 31, 1997, 1998 and 1999, the Company incurred expenses of
approximately $215,000, $648,000 and $1,192,000, respectively, related to the
Rush Plan.

Through March 1998, South Coast Peterbilt also had a defined contribution
pension plan (the South Coast Plan) which was available to all employees of
South Coast Peterbilt. Effective April 1, 1998, the South Coast Plan was
terminated at which time all eligible South Coast employees were permitted to
enter the Rush Plan. During the years ended December 31, 1997 and 1998, South
Coast incurred expenses of approximately $151,000 and $46,000, respectively,
related to the South Coast Plan.

The Company currently does not provide any postretirement benefits other than
pensions nor does it provide any postemployment benefits.

10.  LEASES:

11.  STOCK OPTIONS AND STOCK PURCHASE WARRANTS:

In October 1995, Statement of Financial Accounting Standards No. 123,
"Accounting for Stock-Based Compensation" (SFAS 123), was issued. SFAS 123
defines a fair value based method of accounting for employee stock options or
similar equity instruments and encourages all entities to adopt that method of
accounting for all of their employee stock compensation plans. Under the fair
value based method, compensation cost is measured at the grant date based on the
value of the award and is recognized over the service period of the award, which
is usually the vesting period. However, SFAS 123 also allows entities to
continue to measure compensation costs for employee




                                       54
<PAGE>   55

stock compensation plans using the intrinsic value method of accounting
prescribed by APB Opinion No. 25, "Accounting for Stock Issued to Employees"
(APB 25). Because the Company has elected to continue to follow APB 25, SFAS 123
requires disclosure of pro forma net income and earnings per share as if the new
fair value accounting method was adopted. The Company has presented the pro
forma information required by SFAS 123.

In April 1996, the Board of Directors and shareholders adopted the Rush
Enterprises, Inc. Long-Term Incentive Plan (the Incentive Plan). The Incentive
Plan provides for the grant of stock options (which may be nonqualified stock
options or incentive stock options for tax purposes), stock appreciation rights
issued independent of or in tandem with such options (SARs), restricted stock
awards and performance awards.

The aggregate number of shares of common stock subject to stock options or SARs
that may be granted to any one participant in any one year under the Incentive
Plan is 100,000 shares. The Company has 650,000 shares of common stock reserved
for issuance upon exercise of any awards granted under the Company's Incentive
Plan.

In connection with the Offering, the Company agreed to issue to the
representatives of the underwriters and their designees, for their own accounts,
warrants to purchase an aggregate of 250,000 shares of common stock. The
warrants are exercisable during the four-year period commencing June 12, 1997,
at an exercise price equal to $14.40 per share.

On April 8, 1996, the Board of Directors of the Company declared a dividend of
one common share purchase right (a Right) for each share of common stock
outstanding. Each Right entitles the registered holder to purchase from the
Company one share of common stock at a price of $35.00 per share (the Purchase
Price). The Rights are not exercisable until the distribution date, as defined.
The Rights will expire on April 7, 2006 (the Final Expiration Date), unless the
Final Expiration Date is extended or unless the Rights are earlier redeemed or
exchanged by the Company.

In March 1997, 1998 and 1999 the Company granted options under the Incentive
Plan to purchase an aggregate of 103,013, 168,140 and 117,150 shares,
respectively, of common stock to employees. Each option granted shall become
exercisable in three annual installments beginning on the third anniversary of
the date of grant. The options are exercisable at a price equal to the fair
value of the Company's common stock at the date of grant.

During 1997, the Board of Directors and shareholders adopted the Rush
Enterprises, Inc. 1997 Non-Employee Director Stock Option Plan (the Director
Plan). The Director Plan is designed to attract and retain highly qualified
non-employee directors, reserving 100,000 shares of common stock for issuance
upon exercise of any awards granted under the Plan. Under the terms of this
plan, each non-employee director received options to purchase 10,000 shares as
of the date of adoption or on their respective date of election, all of which
are fully vested and are exercisable immediately, and expire ten years from the
date of grant. During each of the years ended December 31, 1997, 1998 and 1999,
30,000 options were granted and exercisable at a price equal to the fair values
of the Company's common stock at the dates of grant. 20,000 of these options
have been exercised as of December 31, 1999.

The fair value of these options was estimated using a Black-Scholes option
pricing model with a risk-free interest rate of 5.5% for 1997 and 1998 and 6.0%
for 1999, a volatility factor of .133, .422 and .510 for 1997, 1998 and 1999,
respectively, a dividend yield of 0%, and an expected option life of seven years
for 1997 and 1998 and five years for 1999.

In October 1997, the Company issued warrants to purchase an aggregate of 171,875
shares of common stock to C. Jim Stewart & Stevenson in connection with the
purchase of the assets of the John Deere construction equipment store. The
warrants are exercisable during the five-year period commencing October 6, 1998,
at an exercise price equal to $12.00 per share. None of these warrants have been
exercised as of December 31, 1999.

In March 1998, the Company issued options to purchase an aggregate of 109,793
shares of common stock to the seller in connection with the purchase of the
stock of D & D Farm and Ranch Supermarket, Inc. The options are exercisable in
four annual installments beginning on the second anniversary of the date of
grant, at exercise prices equal to $9.38, $14.38 and $19.38 per share. None of
these options have been exercised as of December 31, 1999.

12.   EARNINGS PER SHARE:

Earnings per share for all periods have been restated to reflect the adoption of
Statement of Financial Accounting Standards No. 128, "Earnings Per Share," (SFAS
128) which established standards for computing and presenting earnings per share
("EPS") for entities with publicly held common stock or potential common stock.
This statement requires dual presentation of basic and diluted EPS on the face
of the income statement for all entities with complex capital structures. Basic
EPS were computed by dividing net income by the weighted average number of
shares of common stock outstanding during the period. Diluted EPS differs from
basic EPS due to the assumed conversions of potentially dilutive options and
warrants that were outstanding during the period. The following is a
reconciliation of the numerators and the denominators of the basic and diluted
per-share computations for net income.

13.  INCOME TAXES:

Prior to the Offering of the Company's common stock, the Company maintained the
status of S corporation for federal and state income tax purposes. As an S
corporation, the Company was generally not responsible for income taxes. Upon
the closing of the Offering, the Company's S corporation election terminated and
the Company was reorganized. Accordingly, the Company became subject to federal
and state income taxes from that date forward.

Upon the Company's termination of its S corporation status, the Company provided
deferred income taxes for cumulative temporary differences between the tax basis
and financial reporting basis of its assets and liabilities at the date of
termination.

The Company is involved in various claims and legal actions arising in the
ordinary course of business. The Company believes it is unlikely that the final
outcome of any of the claims or proceedings to which the Company is a party
would have a material adverse effect on the Company's financial position or
results of operations; however, due to the inherent uncertainty of litigation,
there can be no assurance that the resolution of any particular claim or
proceeding would not have a material adverse effect on the Company's results of
operations for the fiscal period in which such resolution occurred.

The Company has consulting agreements with individuals for an aggregate monthly
payment of $37,786. The agreements expire in 2000 through 2001.

the four-year period commencing March 2, 2000, at exercise prices ranging from
$9.38 to $19.38 per share.

Deere Credit Corp.

17.   SEGMENTS:

The Financial Accounting Standards Board issued Statement of Financial
Accounting Standards No. 131 "Disclosures about Segments of an Enterprise and
Related Information" (SFAS 131). This statement requires that public business
enterprises report certain information about operating segments in complete sets
of financial statements of the enterprise and in condensed financial statements
of interim periods issued to shareholders. It also requires that public business
enterprises report certain information about their products and services, the
geographic areas in which they operate, and their major customers. The effective
date for SFAS No. 131 is for fiscal years beginning after December 15, 1997.

The Company has two reportable segments: the Heavy-duty Truck segment and the
Construction Equipment segment. The Heavy-duty Truck segment operates a regional
network of truck centers that provide an integrated one-stop source for the
trucking needs of its customers, including retail sales of new Peterbilt and
used heavy-duty trucks, after-market parts, service and body shop facilities,
and a wide array of financial services, including the financing of new and used
truck purchases, insurance products and truck leasing and rentals. The
Construction Equipment segment, formed during 1997, operates full-service John
Deere dealerships that serve the Houston, Texas Metropolitan and surrounding
areas and 67 counties in Michigan. Dealership operations include the retail sale
of new and used equipment, after-market parts and service facilities, equipment
rentals, and the financing of new and used equipment.

The accounting policies of the segments are the same as those described in the
summary of significant accounting policies. The Company evaluates performance
based on income before income taxes not including extraordinary items.

The Company accounts for intersegment sales and transfers as if the sales or
transfers were to third parties, that is, at current market prices. There were
no material intersegment sales during the years ended December 31, 1997, 1998
and 1999.

The Company's reportable segments are strategic business units that offer
different products and services. They are managed separately because each
business requires different technology and marketing strategies. Business units
were maintained through expansion and acquisitions. The following table contains
summarized information about reportable segment profit or loss and segment
assets, for the years ended December 31, 1997, 1998 and 1999 (in thousands):

Revenues from segments below the quantitative thresholds are attributable to
four operating segments of the Company. Those segments include a farm and ranch
retail center, a tire company, an insurance company, and a hunting lease
operation. None of those segments has ever met any of the quantitative
thresholds for determining reportable segments.

                                       11
<PAGE>   19

         4.1 Incorporation; Capitalization.

                  (a) Seller is a corporation duly organized, validly existing
         and in good standing under the laws of the State of Michigan, and is
         duly authorized, qualified and licensed under all applicable
         Governmental Requirements to carry on its business in the places and in
         the manner as now conducted and to own, operate and lease the Assets it
         now owns, operates or holds under lease. There has not been any claim
         by any other jurisdiction to the effect that Seller is required to
         qualify or otherwise be authorized to do business as a foreign
         corporation therein in order to carry on any of its businesses as now
         conducted or to own, lease or operate the Assets. Seller has not, to
         Seller's Best Knowledge, taken any action, or failed to take any action
         which such action or such failure will preclude or prevent Seller's
         Business from being conducted in substantially the same manner in which
         Seller has heretofore conducted the same.

         4.2 Employee Benefits. As used in this Section, the "Company" shall
include the Seller and any member of a controlled group or affiliated service
group (as defined in Sections 414(b), (c), (m), and (o) of the Code) of which
the Seller is a member.

                  (a) List of All Benefit Plans and Compensation Agreements.
         Schedule 4.2(a) includes a complete and accurate list of all employee
         welfare benefit and employee pension benefit plans as defined in
         Sections 3(1), 3(2), and 3(3) of ERISA and all other employee benefit
         agreements or arrangements, including but not limited to deferred
         compensation plans, incentive plans, bonus plans or arrangements, stock
         option plans, stock purchase plans, golden parachute agreements,
         severance pay plans, dependent care plans, cafeteria plans, employee
         assistance programs, scholarship programs, employment contracts and
         other similar plans, agreements and arrangements that are currently in
         effect or were maintained within three years of the Closing Date, or
         have been approved before this date but are not yet effective, for the
         benefit of directors, officers, employees, or former employees (or
         beneficiaries of them) of the Seller.

                  (b) Representations. The consummation of this Agreement (and
         the employment by the Purchaser of former employees of the Seller) will
         not result in any carryover liability to the Purchaser for taxes,
         penalties, interest or any other claims resulting from any employee
         pension benefit plan, employee welfare benefit plan, or other employee
         benefit agreement or arrangement set out in Schedule 4.2(a). In
         addition, the Seller makes the following representations (i) as to
         employee pension benefit plans of the Company: (a) no Company has
         become liable to the PBGC under Section 4062, 4063 or 4064 of ERISA
         under which a lien could attach to the assets of the Seller under
         Section 4068 of ERISA; (b) the Company has not ceased operations at a
         facility so as to become subject to the provisions of Section 4062(e)
         of ERISA; and (c) the Company has not made a complete or partial
         withdrawal from a multiemployer plan (as defined in Section 3(37) of
         ERISA) so as to incur withdrawal liability as defined in Section 4201
         of ERISA, and (ii) all group health plans maintained by the Company
         have been operated in compliance with Section 4980B(f) of the Code.

                  (c) Non-assumption of Seller's Plans. The parties agree that
         the Purchaser does not and will not assume the sponsorship of, or the
         responsibility for contributions to, or any liability in connection
         with, any employee pension benefit plan, any employee welfare benefit
         plan, or other employee benefit agreement or arrangement maintained by
         Seller for its employees, former employees, retirees, their
         beneficiaries or any other person. In addition and not as a limitation
         of the foregoing covenant the parties agree that the Seller shall be
         liable for any continuation coverage (including any penalties, excise
         taxes or interest resulting from the failure to provide continuation
         coverage)

of any nature of the Business, whether accrued, absolute, contingent or
otherwise, and whether due, or to become due, including, but not limited to,
liabilities, debts or obligations on account of Taxes to the extent such items

which, with the passage of time or the giving of notice or both, might

contemplated by this Agreement. Seller is not obligated to pay any liquidated
damages under any of the contracts, agreements, indentures, leases or other
instruments described in Schedule 4.8 hereto and Seller is not aware of any
facts or circumstances that could reasonably be expected to result in an

of Seller there is no reason why any of the Contracts (i) will result in a loss
to Purchaser on completion by performance or (ii) cannot readily be fulfilled or
performed by Purchaser with the Assets on time without undue or unusual
expenditure of money or effort. Copies of all of the documents (or in the case
of oral commitments, descriptions of the material terms thereof) relevant to the
Contracts listed in Schedule 4.8 have been delivered by Seller to Purchaser, and
such copies and/or descriptions are true, complete and accurate and include all
amendments, supplements or modifications thereto. After reviewing the Contracts
described on Schedule 4.8, the Purchaser may, at its sole option, choose to
assume one or more of such Contracts, and, within twenty (20) days of receipt by
Purchaser of all information reasonably requested by Purchaser with respect to
such Contracts, Purchaser shall notify Seller of which Contracts, if any,
Purchaser intends to assume hereunder. Except for Contracts, if any, that
Purchaser notifies Seller (in writing) that it will assume, all of the Contracts
described on Schedule 4.8 (but not including any other Contracts, including the
Contracts on Schedule 2.1(p)) shall remain the sole obligation of Seller and
shall not be assumed by Purchaser, and Purchaser shall have no obligation or
liability with respect thereto.

and the consummation of the transactions contemplated hereby will not (a)
violate any provision of the



                                       16
<PAGE>   24

Articles of Incorporation or other charter documents or bylaws of Seller; (b)
result in any violation of any Governmental Requirement applicable to Seller,
the Assets or the Business; (c) conflict with, or result in any breach of, or
default or loss of any right under (or an event or circumstance that, with

creation of an Encumbrance pursuant to, or cause or permit the acceleration
prior to maturity or "put" right with respect to, any obligation under, any
contract, indenture, mortgage, deed of trust, lease, loan agreement or other
agreement or instrument to which Seller is a party or to which any of the Assets
are subject; (d) relieve any Person of any obligation (whether contractual or
otherwise) or enable any Person to accelerate or terminate any such obligation
or any right or benefit enjoyed by Seller or to exercise any right under any
agreement in respect of the Assets or the Business; and (e) require (to the Best
of Seller's Knowledge) notice to or the consent, authorization, approval,
clearance, waiver or order of any Person (except as may be contemplated by the
last sentence of Section 4.8). To the Best Knowledge of Seller, the business
relationships of clients, customers and suppliers of the Business will not be
adversely affected by the execution and delivery of this Agreement or the
consummation of the transactions contemplated hereby. To the Best of Seller's
Knowledge, the execution, delivery and performance of this Agreement by Seller
will not result in the loss of any material governmental license, franchise or
permit possessed by Seller.

tangible property leased by Seller under the Grand Rapids Lease and the

include all existing warranties and service contracts with respect to any of the
Assets, the Real Property, the Ellsworth Property and the Grand Rapids Property
to the extent the same are capable of being assigned to Purchaser. During the
past two years, there has not been any significant interruption of the Business
due to the breakdown or inadequate maintenance of any of the Assets. To the Best
of Seller's Knowledge, all plants, structures, equipment, vehicles and other
tangible properties included in the Assets, the Real Property, the Ellsworth
Property and the Grand Rapids Property and the present use of all such items,
conform to all applicable Governmental Requirements, and no notice of any
violation of any such Governmental Requirements relating to such assets or their
use has been received by Seller. The Assets include all easements, rights of
ingress and egress, and utilities and services necessary for the conduct of the

products, sold or distributed by Seller or services performed by or on behalf of
Seller in connection with the operation of the Business that could reasonably be
expected to materially exceed the reserves therefor.

              (b) To the Best of Seller's Knowledge, there is no state of facts
or any event forming the reasonable basis of any present claim against Seller in
connection with the operation of the Business not fully covered by insurance,
except for deductibles and self-insurance retentions, for personal injury or
property damage alleged to be caused by products shipped or services rendered by
or on behalf of Seller in connection with the operation of the Business.

         4.24 No Untrue Statements. To the Best of Seller's Knowledge, the
statements, representations and warranties of Seller set forth in this Agreement
and the Schedules and in all other documents and information furnished to
Purchaser and its representatives in connection herewith do not include any
untrue statement of a material fact or omit to state any material fact necessary
to make the statements, representations and warranties made not misleading. To
the Best Knowledge of Seller, there is no fact or matter that is not disclosed
to Purchaser in this Agreement or the Schedules that materially and adversely
affects or, so far as Seller can now reasonably foresee, could materially and
adversely affect the condition (financial or otherwise) of any of the Assets or
the Business or the ability of Seller or any of the Shareholders to perform
their respective obligations under this Agreement.

18 to terminate this Agreement or refuse to consummate the transactions
contemplated hereby).

connection with the Assets being sold to Purchaser pursuant hereto, Seller shall

on or prior to the Closing Date (provided that failure by the Rush Parties to

order or agreement shall not constitute a failure of the Rush Parties to use
commercially reasonable efforts), and (d) deliver to Seller at the Closing the
certificate contemplated by Article 11 (with such additions or exceptions to
such certificate as are necessary to make the statements set forth in such
certificate accurate, provided that if any of such additions or exceptions cause

11 not to be fulfilled, such additions and exceptions shall in no way limit the
rights of Seller under Articles 11 and 18 to terminate this Agreement or to
refuse to consummate the transactions contemplated hereby).

covered by a repurchase obligation referred to in Section 3.2(j) and listed on

machinery before selling or disposing of such equipment and machinery, the Rush
Parties shall make all such repairs in consideration for the actual cost of such

         13.8 Procedure. All claims for indemnification or payment under this
Article 13 shall be asserted and resolved as follows:

                  (a) An Indemnitee shall promptly give the Indemnitor written
         notice of any matter which an Indemnitee has determined has given or
         could give rise to a right of indemnification under this Agreement (an
         "Indemnification Event"), stating the amount of the Loss, if known, and
         method of computation thereof, all with reasonable particularity, and
         stating with particularity the nature of such matter. Failure to
         provide such written notice shall not affect the right of the
         Indemnitee to indemnification except to the extent such failure shall
         have resulted in liability to the Indemnitor that could have been
         actually avoided had such notice been provided within such required
         time period and except that an Indemnitor shall not have any liability
         under this Article 13 in the event such written notice is not given
         under within 18 months following the Closing Date.

                  (b) The obligations and liabilities of an Indemnitor under
         this Article 13 with respect to Losses arising from claims of any third
         party that are subject to the indemnification provided for in this
         Article 13 ("Third-Party Claims") shall be governed




                                       33
<PAGE>   41

         by and contingent upon the following additional terms and conditions:
         if an Indemnitee shall receive notice of any Third-Party Claim, the
         Indemnitee shall give the Indemnitor prompt notice of such Third-Party
         Claim and the Indemnitor may, at its option, assume and control the
         defense of such Third-Party Claim at the Indemnitor's expense and
         through counsel of the Indemnitor's choice reasonably acceptable to
         Indemnitee. Subject to the condition that written notice be delivered
         prior to the expiration of one year after the Closing Date, failure to
         provide such written notice shall not affect the right of the
         Indemnitee to indemnification except to the extent such failure shall
         have resulted in liability to the Indemnitor that could have been
         actually avoided had such notice been provided within such required
         time period. In the event the Indemnitor assumes the defense against
         any such Third-Party Claim as provided above, the Indemnitee shall have
         the right to participate at its own expense in the defense of such
         asserted liability, shall cooperate with the Indemnitor in such defense
         and will attempt to make available on a reasonable basis to the
         Indemnitor all witnesses, pertinent records, materials and information
         in its possession or under its control relating thereto as is
         reasonably required by the Indemnitor. In the event the Indemnitor does
         not elect to conduct the defense against any such Third-Party Claim,
         the Indemnitor shall cooperate with the Indemnitee (and be entitled to
         participate) in such defense and attempt to make available to it on a
         reasonable basis all such witnesses, records, materials and information
         in its possession or under its control relating thereto as is
         reasonably required by the Indemnitee. The Indemnitor understands that
         if such Third-Party Claim results in an obligation to indemnify
         hereunder, Damages shall include all reasonable costs and expenses of
         such defense. Except for the settlement of a Third-Party Claim that
         involves the payment of money only and for which the Indemnitor has
         provided written objection to Indemnitee under Section 13.8(c), no
         Third-Party Claim may be settled without the written consent of the
         Indemnitee. Written notice of any proposed settlement of any such claim
         and the material terms thereof shall be delivered by Indemnitee to
         Indemnitor at least five Business Days prior to any settlement of any
         such claim.

                  (c) If a claim for indemnity is provided pursuant to this
         Article 13 by an Indemnitee and the Indemnitor does not pay such claim
         or object to such claim within 20 Business Days after written notice is
         received by the Indemnitor, such claim shall be deemed agreed to by the
         Indemnitor. If the Indemnitor shall object to such claim, a written
         notice of such objection setting forth in reasonable detail the basis
         for such objection shall be provided to the Indemnitee and such dispute
         shall be resolved in accordance with Section 24.12 hereof. In addition,
         if the claim shall have been determined to have been a valid claim,
         Damages shall include interest at the prime rate as quoted from time to
         time by The Frost National Bank from the date the claim is first made
         until fully paid.

         13.9 Payment. Payment of any amounts due pursuant to this Article 13
shall be made within ten Business Days after final adjudication of such claim
and after written notice is sent by the Indemnitee.

         13.10 Failure to Pay Indemnification. If and to the extent the
Indemnitee shall make written demand upon the Indemnitor for indemnification
pursuant to this Article 13 and the Indemnitor shall refuse or fail to pay in
full within 20 Business Days of such written demand the amounts demanded
pursuant hereto and in accordance herewith, then the Indemnitee shall proceed in
accordance with the arbitration provisions of Section 24.12 hereof; provided,
however,




                                       34
<PAGE>   42

that in the case of indemnification for a Third-Party Claim, such matter need
not be resolved by arbitration until the underlying Third-Party Claim is finally
resolved.

         13.11 Cooperation. The Indemnitor and the Indemnitee shall cooperate
with each other with regard to any indemnification obligation under this Article
13 and each shall attempt to make available to the other on a reasonable basis
all personnel records, materials and information in its possession or under its
control as is reasonably requested by the other.

         14. LEASES. On the Closing Date, Seller shall cause the appropriate
owner(s) of the Real Property to enter into the Leases described in Exhibit D
with Purchaser.

         15. NON-COMPETITION AGREEMENTS.

         15.1 (a) Non-Competition. In consideration of the benefits of this
Agreement to Seller and as a material inducement to the Rush Parties to enter
into this Agreement and pay the Purchase Price, Seller and the Shareholders
hereby covenant and agree that, commencing on the Closing Date and ending on the
second anniversary of the Closing Date, Seller and the Shareholders shall not,
and Seller will cause their Affiliates, officers, directors and representatives,
as applicable, not to, directly or indirectly, as proprietor, partner,
stockholder, director, executive, officer, employee, consultant, joint venturer,
investor or in any other capacity, engage in, or own, manage, operate or
control, or participate in the ownership, management, operation or control, of
any entity which engages in the sales, service and/or rental of construction
equipment and machinery and any similar business activity in Michigan and/or
Texas; provided, however, the foregoing shall not prohibit Seller and the
Shareholders, and their Associates, Affiliates and representatives from
purchasing and holding as an investment not more than 5% of any class of
publicly traded securities of any entity which conducts a business in
competition with the business of the Rush Parties, so long as Seller and each of
the Shareholders, and their Affiliates and representatives do not participate in
any way in the management, operation or control of such entity.

              (b) Permitted Competition. Notwithstanding anything to the
contrary in this Section 15, in the event that the Rush Parties do not assume
any contract, repurchase agreement, recourse retail installment contracts,
guaranteed buyback contracts, or similar undertaking, including the repurchase
obligations set forth on Schedule 15.1(b), then Seller, after repurchasing such
equipment or machinery from a customer, shall be entitled to re-sell or
otherwise dispose of such equipment or machinery to any customer, person or
buyer in Michigan, Texas or elsewhere, on such terms as Seller may deem
appropriate and Seller shall retain 100% of the proceeds from the sale or
disposition of such equipment and machinery.

         15.2 Judicial Reformation. Seller and each of the Shareholders
acknowledge that, given the nature of the Rush Parties' business, the covenants
contained in Section 15.1 establish reasonable limitations as to time,
geographic area and scope of activity to be restrained and do not impose a
greater restraint than is reasonably necessary to protect and preserve the
goodwill of the Rush Parties' business and to protect their legitimate business
interests. If, however, Section 15.1 is determined by any court of competent
jurisdiction to be unenforceable by reason of its extending for too long a
period of time or over too large a geographic area or by reason of it being too
extensive in any other respect or for any other reason, it will be interpreted
to extend only over the longest period of time for which it may be enforceable
and/or over the largest geographic area as to which it may be enforceable and/or
to the maximum extent in all other aspects as to which it may be enforceable,
all as determined by such court.



                                       35
<PAGE>   43
         15.3 Customer Lists; Non-Solicitation. Seller and each of the
Shareholders hereby further covenant and agree that they shall not, and Seller
and each of the Shareholders will cause their Affiliates and representatives not
to, directly or indirectly, (a) use or make known to any person or entity the
names or addresses of any clients or customers of Seller or the Rush Parties or
any other information pertaining to them, provided, however, such limitation
shall not apply to any information which (i) is then generally known to the
public; (ii) become or becomes generally known to the public through no fault of
Seller and any of the Shareholders, its Affiliates and representatives, and
(iii) is disclosed in accordance with an order of a court of competent
jurisdiction or applicable law, (b) call on, solicit, or attempt to call on or
solicit any clients or customers of Seller or the Rush Parties, nor (c) solicit
for employment, recruit, hire or attempt to recruit or hire any employees of
Seller or the Rush Parties.

         15.4 Covenants Independent. The covenants of each of Seller and each of
the Shareholders contained in this Section 15 will be construed as independent
of any other provision in this Agreement, and the existence of any claim or
cause of action by Seller or any of Shareholders against the Rush Parties will
not constitute a defense to the enforcement by the Rush Parties of said
provisions. Seller and each of the Shareholders understand that the provisions
contained in Sections 15.1, 15.2 and 15.3 are essential elements of the
transactions contemplated by this Agreement and, but for the agreement of Seller
and each of the Shareholders to Sections 15.1, 15.2 and 15.3, the Rush Parties
would not have agreed to enter into this Agreement and the transactions
contemplated herein. Seller and each of the Shareholders have been advised to
consult with counsel in order to be informed in all respects concerning the
reasonableness and propriety of Sections 15.1, 15.2 and 15.3 with specific
regard to the nature of the business conducted by Seller and the Rush Parties
and Seller and each of the Shareholders acknowledge that Sections 15.1, 15.2 and
15.3 are reasonable in all respects.

         15.5 Remedies. In the event of a breach or a threatened breach by
Seller or any of the Shareholders of any of the provisions contained in Sections
15.1, 15.2 or 15.3 of this Agreement, Seller and each of the Shareholders
acknowledge that the Rush Parties will suffer irreparable damage or injury not
fully compensable by money damages, or the exact amount of which may be
impossible to obtain, and, therefore, will not have an adequate remedy available
at law. Accordingly, the Rush Parties shall be entitled to obtain such
injunctive relief or other equitable remedy, without the necessity of posting
bond therefor, from any court of competent jurisdiction as may be necessary or
appropriate to prevent or curtail any such breach, threatened or actual. The
foregoing shall be in addition to and without prejudice to any other rights that
the Rush Parties may have under this Agreement, at law or in equity, including,
without limitation, the right to sue for damages.

         16. NONDISCLOSURE OF CONFIDENTIAL INFORMATION. Seller and each of the
Shareholders recognize and acknowledge that they have and will have access to
certain confidential information of Seller that is included in the Assets
(including, but not limited to, lists of customers, trade secrets, costs and
financial information) that after the consummation of the transactions
contemplated hereby will be valuable, special and unique property of the Rush
Parties. Seller and each of the Shareholders agree that Seller and each of the
Shareholders will, and will cause their Affiliates and representatives to, keep
confidential and not disclose to any other Person or use for his or its own
benefit or for the benefit of any other Person, and Seller and each of the
Shareholders will use their best efforts to prevent disclosure by any other
Person of, any such confidential information to any Person for any purpose or
reason whatsoever, except to authorized representatives of the Rush Parties;
provided, however, such limitation shall not apply to any information which (a)
is then generally known to the public, (b) become or becomes generally known to
the public through no fault of Seller or any of



                                       36
<PAGE>   44

the Shareholders, or their respective Affiliates and representatives, and (c) is
disclosed in accordance with an order of a court of competent jurisdiction or
applicable law. In the event of a breach or a threatened breach by Seller or any
of the Shareholders of any of the provisions contained in this Article 16,
Seller and each of the Shareholders acknowledge that the Rush Parties will
suffer irreparable damage or injury not fully compensable by money damages, or
the exact amount of which may be impossible to obtain, and, therefore, will not
have an adequate remedy available at law. Accordingly, the Rush Parties shall be
entitled to obtain such injunctive relief or other equitable remedy, without the
necessity of posting bond therefor, from any court of competent jurisdiction as
may be necessary or appropriate to prevent or curtail any such breach,
threatened or actual. The foregoing shall be in addition to and without
prejudice to any other rights that the Rush Parties may have under this
Agreement, at law or in equity, including, without limitation, the right to sue
for damages.

         17. DAMAGE TO ASSETS. If, on or before the Closing Date, any of the
Assets are damaged or destroyed, Seller will immediately notify the Rush Parties
of such damage or destruction. In the event of any such damage or destruction,
the Purchaser shall (a) remove any or all of the damaged or destroyed asset or
assets it does not desire to purchase from the Assets to be purchased hereunder
and reduce the Purchase Price by an amount equal to the portion of the Purchase
Price attributable to the damaged or destroyed asset or assets so removed and
(b) complete the purchase of the remainder of the Assets and reduce the Purchase
Price by the loss in fair market value of any damaged or destroyed Assets that
are purchased by Purchaser. If, on or before the Closing Date, all or any
portion of the Real Property or the Grand Rapids Property (including, without
limitation, any of the buildings or other improvements thereon) is damaged or
destroyed by fire or other casualty or wholly or partially taken by condemnation
or eminent domain or action in lieu thereof, then Seller shall immediately
notify the Rush Parties thereof, whereupon the Rush Parties shall have the
option of (i) requiring Seller to repair and restore the damaged parcel to the
condition it was in as of the date hereof, immediately upon Seller's receipt of
the casualty insurance proceeds or condemnation award therefor (as applicable),
in which event the Closing hereunder (as to either the entirety of this
transaction or just the parcel so affected, at the Rush Parties' election) shall
be delayed until such repairs are complete, (ii) proceeding to Closing upon
Seller's assignment to Purchaser of all casualty insurance proceeds or
condemnation awards associated with such damage, destruction or taking, (iii)
electing not to enter into a Lease with respect to any parcel of Real Property
so damaged, destroyed or taken, (iv) electing to enter into a Lease with respect
to any such parcel so damaged, destroyed or taken, but with a fair and equitable
reduction in the rental rate therefor determined by mutual agreement of the
owner thereof and the Rush Parties, or (v) if such damage, destruction or taking
affects the Grand Rapids Property, electing not to take assignment of the Grand
Rapids Lease or, at the Rush Parties' option, postponing acceptance of such
assignment until such time as the results of the damage, destruction or taking
of the Grand Rapids Property have been repaired or otherwise resolved in
accordance with the terms of the Grand Rapids Lease), or (vi) if such damage,
destruction or taking affects the Ellsworth Property, electing not to enter into
the New Ellsworth Lease or, at the Rush Parties' option, postponing the entering
into of the New Ellsworth Lease until such time as the results of the damage,
destruction or taking of the Ellsworth Property have been repaired or otherwise
resolved in accordance with the terms of the Ellsworth Lease).

         18. TERMINATION. This Agreement may be terminated without further
obligation of the parties, as follows:

         18.1 Mutual Consent. This Agreement may be terminated at any time prior

<PAGE>   45
         18.2 Failure of Conditions. This Agreement may be terminated by either
party hereto, if the conditions, as set forth in this Agreement, to such party's
obligations under this Agreement are not fulfilled on or prior to the Closing
Date; provided that any such termination shall not limit the remedies otherwise
available to such party as a result of misrepresentations of or breaches by the
other party.

         18.3 Failure to Close. This Agreement will automatically terminate on
October 31, 1998, if the Closing shall not have occurred on or before such date,
unless the parties shall have otherwise agreed in writing prior to such date. No
party will be liable in damages to any other party as a result of termination
pursuant to this Section 18.3 unless the failure of the Closing was due to the
failure of such party to comply with the terms of this Agreement.

         19. SPECIAL PROVISIONS REGARDING EMPLOYEES OF SELLER.

         19.1 New Employees of Purchaser. It is the intention of Purchaser, and
Seller hereby acknowledges and agrees with such position, that any employees of
Seller that Purchaser hires will be new employees of Purchaser as of the Closing
Date or the date of hire, whichever is later. Such new employees shall be
entitled only to such compensation and employee benefits as are agreed to by
such employees and Purchaser, or as are otherwise provided by Purchaser, in its
sole discretion.

         19.2 No Hiring Commitment. Purchaser specifically does not commit to
hire any of the employees of the Business, and Seller specifically understands
and acknowledges this fact. However, notwithstanding Purchaser's position,
Purchaser will review its needs in anticipation of the purchase of the Assets
with a view to hiring certain of the employees of Seller as of the Closing Date.
In its review, Purchaser expects to be able to review employee records and
conduct employee interviews. Seller agrees that after the date hereof it will
make, on a confidential basis, its employee records available to Purchaser and
permit Purchaser to contact its employees for the purpose of conducting employee
interviews. Seller further agrees to make employees designated by Purchaser
available to Purchaser for such purpose.

         19.3  Vacation, Sick Pay, Health Insurance, etc.

                  (a) Notwithstanding Purchaser's decision to hire any or all of
         such employees after the Closing Date, Purchaser shall not be liable
         under any bonus plan or other plan described in Schedule 4.2(a) or
         under any other similar plan that may have been established by Seller
         or for any health insurance benefits that may have accrued to such
         employees prior to the Closing Date, and Seller expressly acknowledges
         that it has sole liability for all such employee benefit costs accrued
         as of the Closing Date whether or not any or all of such employees are
         subsequently hired by Purchaser pursuant to Section 19.1.
         Notwithstanding the foregoing, Purchase shall assume at the Closing
         Seller's obligations to employees of Seller actually hired by Purchaser
         for accrued but unused vacation and sick leave, which shall include (i)
         accrued vacation and sick leave through each employee's previous
         anniversary date and (ii) the pro rata portion of vacation and sick
         leave earned by each employee since the last anniversary date through
         the Closing Date, which such vacation and sick leave will be available
         to employee following his next anniversary, and the Purchase Price
         shall be reduced by the dollar value of such obligation; provided,
         however, Purchaser shall only assume up to the number of accrued but
         unused vacation and sick leave days that each employee of Seller
         actually hired by Purchaser would be entitled to under Purchaser's
         vacation day and sick leave policy. Except for vacation and sick leave
         time assumed by Purchaser as set forth above,




                                       38
<PAGE>   46



         Purchaser shall have no obligation after the Closing to continue any
         pension plans or work benefit plans currently offered by Seller to its
         employees.

                  (b) With respect to employees actually employed by Purchaser,
         Seller will remain responsible for medical expenses covered under its
         plans (i) actually incurred prior to the Closing Date or (ii) actually
         incurred with respect to any hospitalization that begins prior to the
         Closing Date until such hospitalization ends (as required under such
         plans), and Purchaser will be responsible for all other medical
         expenses incurred on or after the Closing Date to the extent covered
         under its plans; provided, however, the employees will be treated as
         newly hired employees of Purchaser beginning on the Closing Date
         insofar as medical expenses paid under Purchaser's plans affects the
         time or amount of coverage. Seller shall cooperate with Purchaser to
         provide continuity of such insurance coverage to such employees. Seller
         shall be solely responsible for any obligations under the Consolidated
         Omnibus Budget Reconciliation Act, as amended, with respect to its
         employees.

         19.4 Severance Benefits; Employment Termination. Purchaser shall have
no obligation whatsoever to pay all or any part of any severance benefits that
Seller is or may be obligated to pay in connection with the termination of
employment by Seller of any of its employees.

         19.5 Employee Benefit Plans. Purchaser shall not and does not hereby
assume, continue or maintain any pension, retirement or welfare plans, severance
or vacation policies or benefits, or other employee compensation or benefit
arrangements or policies or plans maintained by Seller for its employees. It is
intended that Purchaser shall not at any time be a successor employer for
purposes of Title IV of the Employee Retirement Income Security Act of 1974, as
amended ("ERISA"). Seller hereby represents and warrants to Purchaser that the
consummation of this Agreement (and the employment by the Purchaser of former
employees of the Seller) will not result in any carryover liability to the
Purchaser for taxes, penalties, interest or any other claims resulting from any
employee pension benefit plan, employee welfare benefit plan, or other employee
benefit agreement or arrangement maintained by Seller. In addition, the Seller
makes the following representations (a) as to employee pension benefit plans of
Seller: (i) Seller has not become liable to the PBGC under Section 4062, 4063 or
4064 of ERISA under which a lien could attach to the assets of the Seller under
Section 4068 of ERISA; (ii) Seller has not ceased operations at a facility so as
to become subject to the provisions of Section 4062(e) of ERISA; and (iii)
Seller has not made a complete or partial withdrawal from a multiemployer plan
(as defined in Section 3(37) of ERISA) so as to incur withdrawal liability as
defined in Section 4201 of ERISA, and (b) all group health plans maintained by
Seller have been operated in compliance with Section 4980B(f) of the Code. In
addition, the parties agree that the Purchaser does not and will not assume the
sponsorship of, or the responsibility for contributions to, or any liability in
connection with, any employee pension benefit plan, any employee welfare benefit
plan, or other employee benefit agreement or arrangement maintained by Seller
for its employees, former employees, retirees, their beneficiaries or any other
person. In addition and not as a limitation of the foregoing covenant, the
parties agree that the Seller shall be liable for any continuation coverage
(including any penalties, excise taxes or interest resulting from the failure to
provide continuation coverage) required by Section 4980B of the Code due to
qualifying events which occur on or before Closing Date.

         19.6 Reporting of Data. Purchaser and Seller shall complete and furnish
to each other such other employee data as shall be reasonably required from time
to time for each party to perform and fulfill its obligations under this Article
19.




                                       39
<PAGE>   47
         19.7 Employment Related Claims. Seller agrees that it, and not
Purchaser, shall be solely responsible for, and Seller hereby agrees to
indemnify, defend and hold harmless Purchaser from and against, all liability,
costs and expenses (including reasonable attorneys' fees) for all existing
employment claims that have been filed by any employee or former employee of
Seller prior to the Closing Date relating to arbitrations, unfair labor practice
charges, employment discrimination charges, wrongful termination claims,
workers' compensation claims, any employment-related tort claim or other claims
or charges of or by employees of Seller, or any thereof filed after the Closing
Date but arising as a result of conditions, actions or events or series of
actions or events which occurred prior to the Closing Date. Schedule 19.7 hereto
sets forth a brief description of any of such claims that have been filed or, to
Seller's knowledge, threatened. Without in any way limiting the foregoing,
Seller shall defend and hold harmless Purchaser from and against any and all
claims, demands, actions, judgments, costs and expenses, including without
limitation, attorney fees and settlement costs and other reasonable expenses,
related to all liabilities and obligations in connection with Seller's qualified
pension, retirement or welfare plans, severance or vacation policies or
benefits, or other employee compensation or benefit arrangements or policies.

         20. ACCESS TO INFORMATION. Seller, Shareholders and the Rush Parties
shall reasonably cooperate with each other after the Closing so that (subject to
any limitations that are reasonably required to preserve any applicable
attorney-client privilege) each party has access to the employees, files, books,
business records, contracts and other information existing at the Closing and
relating to the Assets and the Business as is reasonably necessary for (a) any
customer inquiry or audit, (b) the preparation for or the prosecution or defense
of any suit, action, litigation or administrative, arbitration or other
proceeding or investigation by or against Seller, the Shareholders or the Rush
Parties (other than one by or on behalf of a party to this Agreement), (c) the
preparation and filing of any tax return or election relating the Assets or the
Business or any audit by any taxing authority of any returns of the Rush
Parties, Seller or the Shareholders relating thereto, (d) the preparation and
filing of any other documents required by any Governmental Authority or (e) any
other valid business purpose. The party requesting such information and
assistance shall reimburse the other party for all out-of-pocket costs and
expenses incurred by such party in providing such information and in rendering
such assistance other than attorney fees. The access to the employees, files,
books, records, contracts and other information contemplated herein shall be
during normal business hours and upon not less than five (5) business days'
prior written request, shall be subject to such reasonable limitations as the
party having custody or control thereof may impose to preserve the
confidentiality of information contained therein, and shall not extend to
material subject to a valid claim of privilege unless expressly waived by the
party entitled to claim the same.

         21. ADJUSTMENT OF PURCHASE PRICE. The Purchase Price shall be adjusted
on the Closing Date (a) to reduce the Purchase Price by the amount allocated to
any damaged or destroyed Assets as contemplated by Article 17; (b) to reduce the
Purchase Price by the amount to be credited to Purchaser as described on the
first page of Schedule 2.1(p); (c) to account for a proration of real and
personal property taxes on the Assets, lease deposits, lease payments, utilities
and other items commonly prorated; and (d) to account for any Deposits held by
Seller on the Closing Date. Three days prior to the Closing Date, Seller will
provide the Rush Parties with a statement of adjustments showing all proposed
adjustments to the Purchase Price, such statement of adjustments having all
reasonable backup documentation for such suggested adjustments. The Rush Parties
and Seller will work to finalize all required adjustments prior to the Closing
Date.

         22.  SURVEYS; TITLE COMMITMENT AND CONDITION OF TITLE.

         22.1 Surveys. Within twenty (20) days from and after the date hereof,
the Rush Parties shall have the right, at their sole option and at their sole
cost and expense, to obtain an ALTA or equivalent boundary and improvements
surveys of all or any portion of the Real Property, the Ellsworth Property and
the Grand Rapids Property (whether one or more, the "Surveys"), prepared by a
professional engineer or land surveyor licensed by the State of Michigan and in
form and substance satisfactory to the Rush Parties. Should the Rush Parties
elect to obtain a survey of the Grand Rapids Property or the Ellsworth Property,
Seller agrees to use its best efforts to obtain the consent of the Grand Rapids
Landlord or the Ellsworth Landlord, as the case may be, to the performance of
such survey, if required under the Grand Rapids Lease or the Ellsworth Lease,
and the twenty day time period provided for in this Section 23.1 shall not begin
running until such time as such consent is obtained.

         22.2 Title Commitment. Within ten days from and after the date hereof,
at Seller's sole cost and expense, Seller agrees to cause the Title Company to
furnish Purchaser and its counsel Commitments for Leasehold Policy of Title
Insurance (each, a "Title Commitment" and collectively, the "Title Commitments")
prepared and issued by the Title Company describing and covering the Real
Property, the Ellsworth Property and the Grand Rapids Property, listing
Purchaser as the prospective named insured and showing as the policy amounts the
amounts set forth in Schedule 22.2 hereto. The Title Commitments shall
constitute the commitment of the Title Company to insure, by title insurance in
the standard form promulgated in the State of Michigan, Purchaser's leasehold
interests in the Real Property, the Ellsworth Property and the Grand Rapids
Property, subject to the standard printed exceptions on such promulgated form,
except as modified below. The standard exception as to the lien for taxes shall
be limited to the year of Closing, and shall be endorsed "Not Yet Due and
Payable." The Title Commitments shall contain no exception for "rights of
parties in possession" (other than Purchaser). Further, the Title Commitments
shall incorporate the Title Company's commitment to provide (i) an ALTA Form 9
or CLTA Form 100 endorsement (or the closest equivalent thereto available in the
State of Michigan) and (ii) an ALTA Form 3 or CLTA Form 123 endorsement (or the
closest equivalent thereto available in the State of Michigan), to each of the
policies of title insurance to be issued pursuant thereto.

         22.3 Disclosure of Exceptions by Title Commitments and UCC Report.
Purchaser shall have a period of 15 days from the last to be delivered to
Purchaser and its counsel of each of the Surveys, UCC Report, Title Commitments
and the documents referred to therein as conditions or exceptions to title in
which to review such items and to deliver to Seller in writing such objections
as Purchaser may have to anything contained or set forth in the Surveys, UCC
Report, Title Commitments or title exception documents. Any items to which
Purchaser does not object within such period shall be deemed to be permitted
exceptions hereunder and under the applicable Leases and the Grand Rapids Lease
or the New Ellsworth Lease, as applicable ("Permitted Exceptions"). In the event
the Rush Parties timely object to any matter contained in the Surveys, UCC
Report, Title Commitments or title exception documents, Seller shall have a
reasonable time, not to exceed fifteen days from the date such objections are
made known in writing to Seller, to cure such objections. Any curative actions
shall be completed and all curative materials shall be filed by Seller, at its
sole cost and expense, within such 15-day period. If Seller cannot cure the
objections within such fifteen-day period, Purchaser shall have the option to
(a) cancel this Agreement, in which event the parties shall have no further
obligations hereunder; or (b) waive the objections, and proceed to close the
transaction contemplated hereby in which event such objections shall be included
as exceptions in the Leases, the Grand Rapids Lease, or the New Ellsworth Lease
as applicable.

         23.  ENVIRONMENTAL STUDIES AND REMEDIATION ACTIVITIES.

         23.1 Environmental Studies. Seller has heretofore provided to the Rush
Parties copies of (a) all existing Environmental Site Assessments (whether Phase
I, Phase II or otherwise) covering all or any portion of the Real Property, the
Ellsworth Property and the Grand Rapids Property, to the extent the same are in
Seller's possession or Seller has access to them, and (b) any other
environmental studies, reports and information, including, without limitation,
correspondence from Governmental Authorities, concerning the environmental
condition of the Real Property, the Ellsworth Property and the Grand Rapids
Property, to the extent the same are in Seller's possession or Seller has access
to them (all of the foregoing information, whether obtained by the Rush Parties
or provided by Seller, being hereinafter referred to as "Environmental
Information"). Without in any way limiting the provisions of the preceding
sentence, the Rush Parties and their contractors and representatives, at the
Rush Parties' expense, shall have at least 45 days from the date hereof, but in
no event less than 30 days from receipt of the Environmental Information (the
"Feasibility Period") within which to conduct any and all engineering,
environmental and economic feasibility studies and tests of the Real Property,
the Ellsworth Property and its Grand Rapids Property which the Rush Parties, in
their sole discretion, deem necessary to determine whether the Real Property,
the Ellsworth Property and the Grand Rapids Property are environmentally,
engineeringly and economically suitable for the Rush Parties' intended use. In
accordance with Section 8.6 hereof, Seller has granted and hereby grants to the
Rush Parties and their contractors and representatives access to the Real
Property, the Ellsworth Property and the Grand Rapids Property for the purpose
of performing such studies or tests. Such persons shall conduct their studies
and tests in such a manner as to minimize interference with the Business, and,
upon completion of their activities on the Real Property, the Ellsworth Property
and the Grand Rapids Property, shall restore the Real Property, the Ellsworth
Property and the Grand Rapids Property as nearly as is reasonably possible to
the condition they were in immediately prior to such activities.

         23.2 Remediation. In the event that any of the Environmental
Information or any studies or tests performed or commissioned by the Rush
Parties indicate the existence of any Environmental Conditions on the Real
Property, the Ellsworth Property or the Grand Rapids Property, then Seller shall
have a period of 30 days after notification thereof in which to remediate or
otherwise cure the same in accordance with all applicable Governmental
Requirements. In the event that an Environmental Condition exists or is
discovered on the Real Property, the Ellsworth Property or the Grand Rapids
Property and Seller fails or refuses to remediate or otherwise cure such
Environmental Condition within the required 30-day period, or in the event such
Environmental Condition is not capable of being remediated or otherwise cured
within such 30-day period, then Purchaser shall have the following options: (a)
cancel this Agreement by written notice thereof given to Seller prior to the
Closing Date, in which event the parties hereto shall have no further
obligations hereunder, (b) to postpone the leasing of all or any portion of the
Real Property or the assumption of the Grand Rapids Lease or the Ellsworth
Lease, as the case may be, for a reasonable period pending Seller's remediation
of such Environmental Condition, or (c) waive in writing the remediation or cure
of such Environmental Condition and proceed to close the sale and other
transactions contemplated by this Agreement.

         24. GENERAL PROVISIONS.

         24.1 Governing Law; Interpretation; Section Headings. This Agreement
shall be governed by and construed and enforced in accordance with the laws of
the State of Texas, without regard to conflict-of-laws rules as applied in
Texas. The section headings contained



                                       42
<PAGE>   50

herein are for purposes of convenience only, and shall not be deemed to
constitute a part of this Agreement or to affect the meaning or interpretation
of this Agreement in any way.

         24.2 Severability. Should any provision of this Agreement be held
unenforceable or invalid under the laws of the United States of America or the
State of Texas, or under any other applicable laws of any other jurisdiction,
then the parties hereto agree that such provision shall be deemed modified for
purposes of performance of this Agreement in such jurisdiction to the extent
necessary to render it lawful and enforceable, or if such a modification is not
possible without materially altering the intention of the parties hereto, then
such provision shall be severed herefrom for purposes of performance of this
Agreement in such jurisdiction. The validity of the remaining provisions of this
Agreement shall not be affected by any such modification or severance, except
that if any severance materially alters the intentions of the parties hereto as
expressed herein (a modification being permitted only if there is no material
alteration), then the parties hereto shall use commercially reasonable efforts
to agree to appropriate equitable amendments to this Agreement in light of such
severance, and if no such agreement can be reached within a reasonable time, any
party hereto may initiate arbitration under the then current commercial
arbitration rules of the American Arbitration Association to determine and
effect such appropriate equitable amendments.

         24.3 Entire Agreement. This Agreement, the Schedules and the documents
and agreements referenced herein set forth the entire agreement and
understanding of the parties hereto with respect to the transactions
contemplated hereby, and supersede all prior agreements, arrangements and
understandings related to the subject matter hereof. No representation, promise,
inducement or statement of intention has been made by any party hereto which is
not embodied or referenced in this Agreement, the Schedules or the documents or

parties hereto shall not be assigned or delegated by any party hereto without

         24.6 Amendment; Waiver. This Agreement may be amended, modified,
superseded or canceled, and any of the terms, provisions, representations,
warranties, covenants or conditions hereof may be waived, only by a written
instrument executed by all parties hereto, or, in the case of a waiver, by the
party waiving compliance. The failure of any party at any time or times to
require performance of any provision hereof shall in no manner affect the right
to enforce the same. No waiver by any party of any condition contained in this
Agreement, or of the breach of any term, provision, representation, warranty or
covenant contained in this Agreement, in any one or more instances, shall be
deemed to be or construed as a further or continuing waiver of any such
condition or breach, or as a waiver of any other condition or of the breach of
any other term, provision, representation, warranty or covenant.

         24.7 Gender; Numbers. All references in this Agreement to the

         24.8 Counterparts. This Agreement may be executed simultaneously in two
or more counterparts, each of which shall be deemed an original, but all of
which together shall constitute one and the same instrument. This Agreement
shall be binding when one or more counterparts hereof, individually or taken
together, shall bear the signatures of the parties reflected hereon as

such execution and delivery shall be considered valid, binding and effective for
all purposes. At the request of any party hereto, all parties hereto agree to
execute an original of this Agreement as well as any facsimile, telecopy or
other reproduction hereof.

         24.10 Press Releases. No press releases or other public announcement
with respect to this Agreement or the transactions contemplated herein shall be
made prior to the Closing Date without the joint approval of Purchaser and
Seller, except as required by law.

         24.11 Expenses. Whether or not the transactions contemplated hereby are
consummated, each of the parties will pay all costs and expenses of its or his
performance of and compliance with this Agreement.

         24.12 Arbitration. Except for the provisions of Articles 15 and 16 of
this Agreement dealing with restrictive covenants and nondisclosure of
confidential information, with respect to which the Rush Parties expressly
reserve the right to petition a court directly for injunctive and other relief,
any controversy of any nature whatsoever, including but not limited to tort
claims or contract disputes, between the parties to this Agreement or their
respective heirs, executors, administrators, legal representatives, successors
and assigns, as applicable, arising out of or related to this Agreement,
including the implementation, applicability and interpretation thereof, shall,
upon the written request of one party served upon the other, be submitted to and
settled by arbitration in accordance with the provisions of the Federal
Arbitration Act, 9 U.S.C. Sections 1-15, as amended. The terms of the commercial
arbitration rules of the American Arbitration Association shall apply except to
the extent they conflict with the provisions of this paragraph. If the amount in
controversy in the arbitration exceeds Two Hundred and Fifty Thousand Dollars
($250,000), exclusive of interest, attorneys' fees and costs, the arbitration
shall be conducted by a panel of three independent arbitrators. Otherwise, the
arbitration shall be conducted by a single independent arbitrator. The parties
shall endeavor to select independent arbitrators by mutual agreement. If such
agreement cannot be reached within 30 calendar days after a dispute has arisen
which is to be decided by arbitration, the selection of the arbitrator(s) shall
be made in accordance with Rule 13 of the Rules as presently in effect. If three
arbitrators are selected, the arbitrators shall elect a chairperson to preside
at all meetings and hearings. If a dispute is to be resolved by a sole
arbitrator in accordance with the terms hereof, or if the dispute is to be
resolved by a panel of three arbitrators as provided hereinabove, then each such
arbitrator shall be a member of a state bar engaged in the practice of law in
the United States or a retired member of a state or the federal judiciary in the
United States. The award of the arbitrator(s) shall require a majority of the
arbitrators in the case of a panel of arbitrators, shall be based on the
evidence admitted and the substantive law of the State of Texas and shall
contain an award for each issue and counterclaim. The award shall be made 30
days following the close of the final hearing and the filing of any post hearing
briefs authorized by the arbitrator(s). The award of the arbitrator(s) shall be
final and binding on the parties hereto. Each party shall be entitled to inspect
and obtain a copy of non-privileged



                                       44
<PAGE>   52

relevant documents in the possession or control of the other party. All such
discovery shall be in accordance with procedures approved by the arbitrator(s).
Unless otherwise provided in the award, each party shall bear its own costs of
discovery. Each party shall be entitled to take one deposition. Each party shall
be entitled to submit one set of interrogatories which require no more than 30
answers. All discovery shall be expedited, consistent with the nature and
complexity of the claim or dispute and consistent with fairness and justice. The
arbitrator(s) shall have the power to compel any party to comply with discovery
requests of the other parties and to issue binding orders relating to any
discovery dispute which shall be enforceable in the same manner as awards. The
arbitrator(s) also shall have the power to impose sanctions for abuse or
frustration of the arbitration process, including without limitation, the
refusal to comply with orders of the arbitrator(s) relating to discovery and
compliance with subpoenas. Without limiting the scope of the parties' obligation
to arbitrate disputes pursuant to this Section 24.12, the arbitrator(s) are not
empowered to award damages including, without limitation, punitive damages and
multiple damages under applicable Texas statutes, in excess of compensatory
damages; provided that in no event shall consequential damages be awarded. Each
of Rush, Purchaser and Seller hereby irrevocably waives and releases any right
to recover such damages in excess of those damages authorized by this Section
24.12. The arbitrator(s) may require the non- prevailing party to pay the
prevailing party's attorneys' fees and costs incurred in connection with the
arbitration. It is further agreed that any of the parties hereto may petition
the United States District Court for the Western District of Texas, San Antonio
Division, for a judgment to be entered upon any award entered through such
arbitration proceedings.

         In the event that any of the Shareholders is required to travel to
Texas to attend any hearing or deposition in connection with arbitration
proceedings pursuant to this Section 24.12, the Rush Parties shall reimburse
each such Shareholder for his coach air fare and shall pay to such Shareholder a
per diem travel allowance equal to the per diem travel allowance then paid by
Rush to its employees.

         24.13 Assignment of Contracts. Notwithstanding any other provision of
this Agreement, nothing in this Agreement or any related document shall be
construed as an attempt to assign (a) any Contract which, as a matter of law or
by its terms, is nonassignable without the consent of the other parties thereto
unless such consent has been given, or (b) any Contract or claim as to which all
of the remedies for the enforcement thereof enjoyed by Seller would not, as a
matter of law or by its terms, pass to Purchaser as an incident of the transfers
and assignments to be made under this Agreement. In order, however, that the
full value of every Contract and claim of the character described in clauses (a)
and (b) above and all claims and demands on such Contracts may be realized for
the benefit of Purchaser, Seller, at the request and expense and under the
direction of Purchaser, shall take all such action and do or cause to be done
all such things as will, in the opinion of Purchaser, be necessary or proper in
order that the obligations of Seller under such Contracts may be performed in
such manner that the value of such Contract will be preserved and will inure to
the benefit of Purchaser, and for, and to facilitate, the collection of the
moneys due and payable and to become due and payable thereunder to Purchaser in
and under every such contract and claim. Seller shall promptly pay over to
Purchaser all moneys collected by or paid to it in respect of every such
contract, claim or demand. Nothing in this Section 24.13 shall relieve Seller of
its obligations to obtain any consents required for the transfer of the Assets
and all rights thereunder to Purchaser, or shall relieve Seller from any
liability to Purchaser for failure to obtain such consents.

         24.15 Bulk Transfer Laws. Seller, the Shareholders and the Rush Parties
hereby waive compliance by the other parties with the provisions of any bulk

and hold them harmless against, any liabilities, damages, costs and expenses

laws in respect of the transactions contemplated by this Agreement, or (ii) any
action brought or levy made as a result thereof, other than Seller's Obligations
which are assumed by the Rush Parties. The Rush Parties shall indemnify Seller
and the Shareholders from, and hold them harmless against, any liabilities,
damages, costs and expenses resulting from or arising out of (i) the Rush
Parties' failure to comply with any of such laws in respect of the transactions
contemplated by this Agreement, or (ii) any action brought or levy made as a

                                   APPENDIX A

                          DISPUTE RESOLUTION PROCEDURES

         Re: Employment Agreement dated _______ ___, 1998 (including any
amendments, the "Agreement"), between Rush Equipment Centers of Michigan, Inc.,
a Delaware corporation (the "Company"), and __________________________
("Employee"). Unless otherwise defined in this Appendix A, terms defined in the
Agreement and used herein shall have the meanings set forth therein.

         A. Negotiations. If any claim, dispute or controversy described in
Article 7 of the Agreement (collectively, the "Dispute") arises, either party
may, by written notice to the party, have the Dispute referred to the persons
designated below for attempted resolution by good faith negotiations within 45
days after such written notice is received. Such designated persons are as
follows:

         1. Company. The Chairman of the Board and Chief Executive Officer or
his designee; and

         2. Employee. Employee or his designee.

Any settlement reached by the parties under this paragraph A shall not be
binding until reduced to writing and signed by both parties. When reduced to
writing, such settlement agreement shall supersede all other agreements, written
or oral, to the extent such agreements specifically pertain to the matters so
settled. If the above-designated persons are unable to resolve such dispute
within such 45-day period, either party may invoke the provisions of paragraph B
below.

         B. Arbitration. All Disputes shall be settled by negotiation among the
parties as described in paragraph A above or, if such negotiation is
unsuccessful, by binding arbitration in accordance with procedures set forth in
paragraphs C and D below.

         C. Notice. Notice of demand for binding arbitration by one party shall
be given in writing to the other party pursuant to the Agreement. In no event
may a notice of demand of any kind be filed more than one (1) year after the
date the Dispute is first asserted in writing to the other party pursuant to
paragraph A above, and if such demand is not timely filed, the Dispute
referenced in the notice given pursuant to paragraph A above shall be deemed
released, waived, barred and unenforceable for all time, and barred as if by
statute of limitations.

         D. Binding Arbitration. Upon filing of a notice of demand for binding
arbitration by either party, arbitration shall be commenced and conducted as
follows:

            1. Arbitrators. All Disputes and related matters in question shall
be referred to and decided and settled by a panel of three arbitrators, one
selected by the Company, one selected by Employee and the third selected by the
two arbitrators so selected. Selection of the arbitrators to be selected the
Company and Employee shall be made within ten (10) business days after the date
of giving of a notice of demand for arbitration, and the two arbitrators so
appointed shall appoint the third within 10 business days following their
appointment.




                                       A-1
<PAGE>   57
            2. Cost of Arbitration. The cost of arbitration proceedings,
including without limitation the arbitrators' compensation and expenses, hearing
room charges, court reporter transcript charges etc., shall be borne by the
parties equally or otherwise as the arbitrators may determine. The arbitrators
may award the prevailing party its reasonable attorneys' fees and costs incurred
in connection with the arbitration. The arbitrators are specifically instructed
to award attorneys' fees for instances of abuse in the discovery process.

            3. Location of Proceedings. The arbitration proceedings shall be
held in Southfield, Michigan, unless the parties agree otherwise.

            4. Pre-hearing Discovery. The parties shall have the right to
conduct and enforce pre- hearing discovery in accordance with the then current
Federal Rules of Civil Procedure, subject to these limitations:

                  (a) Each party may serve no more than one set of
         interrogatories limited to 30 questions, including sub-parts;

                  (b) Each party may depose the other party's expert witnesses
         who will be called to testify at the hearing, plus two fact witnesses
         without regard to whether they will be called to testify (each party
         will be entitled to a total of no more than 24 hours of deposition time
         of the other party's witnesses), provided however, that the arbitrators
         may provide for additional depositions upon showing of good cause; and

                  (c) Document discovery and other discovery shall be under the
         control of and enforceable by the arbitrators.

            5. Discovery disputes. All discovery disputes shall be decided by
the arbitrators. The arbitrators are empowered;

                  (a) to issue subpoenas to compel pre-hearing document or
         deposition discovery;

                  (b) to enforce the discovery rights and obligations of the
         parties; and

                  (c) to otherwise to control the scheduling and conduct of the
         proceedings.

Notwithstanding any contrary foregoing provisions, the arbitrators shall have
the power and authority to, and to the fullest extent practicable shall,
abbreviate arbitration discovery in a manner which is fair to all parties in
order to expedite the conclusion of each alternative dispute resolution
proceeding.

            6. Pre-hearing Conference. Within fifteen (15) days after selection
of the third arbitrator, or as soon thereafter as is mutually convenient to the
arbitrators, the arbitrators shall hold a pre- hearing conference to establish
schedules for completion of discovery, for exchange of exhibit and witness
lists, for arbitration briefs and for the hearing, and to decide procedural
matters and address all other questions that may be presented.

            7.  Hearing Procedures.  The hearing shall be conducted to preserve
its privacy and to allow reasonable procedural due process. Rules of evidence
need not be strictly followed, and the hearing shall be streamlined as follows:





                                      A-2
<PAGE>   58

                  (a) Documents shall be self-authenticating, subject to valid
         objection by the opposing party;

                  (b) Expert reports, witness biographies, depositions and
         affidavits may be utilized, subject to the opponent's right of a live
         cross-examination of the witness in person;

                  (c) Charts, graphs and summaries shall be utilized to present
         voluminous data, provided (i) that the underlying data is made
         available to the opposing party thirty (30) days prior to the hearing,
         and (ii) that the preparer of each chart, graph or summary is available
         for explanation and live cross-examination in person;

                  (d) The hearing should be held on consecutive business days
         without interruption to the maximum extent practicable; and

                  (e) The arbitrators shall establish all other procedural rules
         for the conduct of the arbitration in accordance with the rules of
         arbitration of the Center for Public Resources.

              8. Governing Law. This arbitration provision shall be governed by,
and all rights and obligations specifically enforceable under and pursuant to,
the Federal Arbitration Act (9 U.S.C. Section 1, et seq.)

              9. Consolidation. No arbitration shall include, by consolidation,
joinder or in any other manner, any additional person not a party to the
Agreement, except by written consent of both parties containing a specific
reference to these provisions.

              10. Award. The arbitrators are empowered to render an award of
general compensatory damages and equitable relief (including, without
limitations, injunctive relief), but are not empowered to award exemplary,
special or punitive damages. The award rendered by the arbitrators (a) shall be
final, (b) shall not constitute a basis for collateral estoppel as to any issue
and (c) shall not be subject to vacation or modification.

              11. Confidentiality. The parties hereto will maintain the
substance of any proceedings hereunder in confidence and the arbitrators, prior
to any proceedings hereunder, will sign an agreement whereby the arbitrators
agree to keep the substance of any proceedings hereunder in confidence.

                                    ARTICLE 4
                                   TERMINATION

         4.1 Termination With Notice. This Agreement may be terminated by the
Company or Employee, without cause, upon 30 days' prior written notice thereof
given by one party to the other party. In the event of termination effected by
the Employee giving notice pursuant to this Section 4.1, the Company shall pay

rata to the date of such termination and the Company shall have no further
obligations to Employee hereunder. In the event of termination effected by the

Employee, within 15 days of such termination, a lump-sum payment equal to his
base salary under Section 3.1 hereof for the remaining portion of his 36-month
term of employment pursuant to this Agreement. Payment by the Company in
accordance with this Section shall constitute Employee's full severance pay and
the Company shall have no further obligation to Employee arising out of such
termination.

         4.2 Termination For Cause. This Agreement may be terminated by the
Company for "Cause" (hereinafter defined) upon written notice thereof given by
the Company to Employee. In the event of termination pursuant to this Section
4.2, the Company shall pay Employee his monthly base salary (subject to standard
deductions) earned pro rata to the date of such termination and the Company
shall have no further obligations to Employee hereunder. The term "Cause" shall
include only the following: (i) Employee breaches any of the terms of this
Agreement; (ii) Employee is convicted of a felony; (iii) Employee fails, after
at least two written warnings, to perform duties assigned under this Agreement
(other than a failure due to death or physical or mental disability); (iv)
Employee intentionally engages in conduct which is injurious to the Company or
its affiliates, monetarily or otherwise; (v) Employee commits fraud or theft of
personal or Company property from Company premises; (vi) Employee falsifies
Company documents or records; (vii) Employee engages in acts of gross
carelessness or willful negligence to endanger life or property on Company
premises; (viii) Employee uses, distributes or is under the influence of illegal
drugs, alcohol or any other intoxicant on Company premises; (ix) Employee
possesses or stores lethal weapons on Company premises; or (x) Employee
intentionally violates state, federal or local laws and regulations.

         4.3 Termination Upon Death or Disability. In the event that Employee
dies, this Agreement shall terminate upon Employee's death. Likewise, if
Employee becomes unable to perform the essential functions of his duties
hereunder, with or without reasonable accommodation, on account of illness,
disability or other reason whatsoever for a period of more than 180 consecutive
or nonconsecutive days in any 12-month period, the Company may, upon notice to
Employee, terminate this Agreement. In the event of termination pursuant to this
Section 4.3, Employee (or his legal representatives) shall be entitled only to
his monthly base salary earned pro rata for services actually rendered prior to
the date of such termination;



                                       4
<PAGE>   69

provided, however, Employee shall not be entitled to his monthly base salary for
any period with respect to which Employee has received short- term or long-term
disability benefits under employee benefit plans maintained from time to time by
the Company.

         4.4 Survival of Provisions. The covenants and provisions of Articles 5,
6 and 7 hereof shall survive any termination of this Agreement and continue for
the periods indicated, regardless of how such termination may be brought about.

                                    ARTICLE 5
                 PROPRIETARY PROPERTY; CONFIDENTIAL INFORMATION

         5.1 Proprietary Property; Confidential Information. Employee
acknowledges that in and as a result of Employee's employment hereunder,
Employee will be making use of, acquiring and/or adding to confidential
information and proprietary property of a special and unique nature and value
relating to such matters as the Company's trade secrets, systems, procedures,
manuals, confidential reports and lists of customers ("Confidential
Information"). As a material inducement to the Company to enter into this
Agreement and to pay to Employee the compensation and benefits stated herein,
the Employee covenants and agrees that Employee shall not, at any time during or
following the term of Employee's employment, directly or indirectly, divulge or
disclose for any purpose whatsoever any Confidential Information or proprietary
information of the Company. Upon termination of this Agreement, regardless of
how such termination may be brought about, Employee shall deliver to the Company
any and all documents, instruments, notes, papers or other expressions or
embodiments of confidential information which are in Employee's possession or
control.

         5.2 Publicity. During the term of this Agreement and for a period of
ten years thereafter, Employee shall not, directly or indirectly, originate or
participate in the origination of any publicity, news release or other public
announcements, written or oral, whether to the public press or otherwise,
relating to this Agreement, to any amendment hereto, to Employee's employment
hereunder or to the Company, without the prior written approval of the Company.

                                    ARTICLE 6
                              RESTRICTIVE COVENANTS

         6.1 Non-Competition. Except as otherwise provided in that certain Asset
Purchase Agreement dated July 12, 1998, between Employee, the Company, Rush and
other parties, in consideration of the benefits of this Agreement, including
Employee's access to and limited use of proprietary and confidential information
of the Company, as well as training, education and experience provided to
Employee by the Company directly and/or as a result of work projects assigned by
the Company with respect thereto, Employee hereby covenants and agrees that
during the term of this Agreement and for a period equal to the longer of (i)
five years from the date hereof, and (ii) two years following termination of
this Agreement, regardless of how such termination may be brought about,
Employee shall not, and the Employee will cause his associates, affiliates and
representatives not to, directly or indirectly, as proprietor, partner,
stockholder, director, officer, employee, consultant, joint venturer, investor
or in any other capacity, engage in, or own, manage, operate or control, or
participate in the ownership, management, operation or control, of any entity
which engages in the sales, service and/or rental of construction equipment and
machinery or any similar business activity in Michigan and/or Texas; provided,
however, the foregoing shall not, prohibit Employee and his associates,
affiliates and representatives from purchasing and holding as an investment not
more than 5%




                                       5
<PAGE>   70

of any class of publicly traded securities of any entity which conducts a
business in competition with the business of the Company, so long as Employee
does not participate in any way in the management, operation or control of such
entity.

         6.2 Reformation. Employee acknowledges that, given the nature of the
Company's business, the covenants contained in Section 6.1 establish reasonable
limitations as to time, geographic area and scope of activity to be restrained
and do not impose a greater restraint than is reasonably necessary to protect
and preserve the goodwill of the Company's business and to protect its
legitimate business interests. If, however, Section 6.1 is determined by any
tribunal of competent jurisdiction to be unenforceable by reason of its
extending for too long a period of time or over too large a geographic area or
by reason of it being too extensive in any other respect or for any other
reason, it will be interpreted to extend only over the longest period of time
for which it may be enforceable and/or over the largest geographic area as to
which it may be enforceable and/or to the maximum extent in all other aspects as
to which it may be enforceable, all as determined by such tribunal.

         6.3 Customer Lists; Non-Solicitation. In consideration of the benefits
of this Agreement, including Employee's access to and limited use of proprietary
and confidential information of the Company, as well as training, education and
experience provided to Employee by the Company directly and/or as a result of
work projects assigned by the Company with respect thereto, Employee hereby
further covenants and agrees that following the termination of this Agreement,
regardless of how such termination may be brought about, Employee shall not,
directly or indirectly, (a) use or make known to any person or entity the names
or addresses of any clients or customers of the Company or any other information
pertaining to them, (b) call on, solicit, take away or attempt to call on,
solicit or take away any clients or customers of the Company on whom Employee
called or with whom he or she became acquainted during his employment with the
Company, nor (c) recruit, hire or attempt to recruit or hire any employees of
the Company.

                                    ARTICLE 7
                                   ARBITRATION

         Except for the provisions of Articles 5 and 6 of this Agreement dealing
with proprietary property, confidential information and restrictive covenants,
with respect to which the Company expressly reserves the right to petition a
court directly for injunctive and other relief, any claim, dispute or
controversy of any nature whatsoever, including but not limited to tort claims
or contract disputes between the parties to this Agreement or their respective
heirs, executors, administrators, legal representatives, successors and assigns,
as applicable, arising out of or related to Employee's employment or the terms
and conditions of this Agreement, including the implementation, applicability or
interpretation thereof, shall be resolved in accordance with the dispute
resolution procedures set forth in Appendix A attached hereto and made a part
hereof.

                                    ARTICLE 8
                                  MISCELLANEOUS

         8.1 Notices. All notices and other communications hereunder shall be in
writing and shall be deemed to have been duly given if delivered personally,

Attention: Chairman of the Board and Chief Executive Officer.

         8.2 Equitable Relief. In the event of a breach or a threatened breach
by Employee of any of the provisions contained in Article 5 or 6 of this
Agreement, Employee acknowledges that the Company will suffer irreparable injury
not fully compensable by money damages and, therefore, will not have an adequate
remedy available at law. Accordingly, the Company shall be entitled to obtain
such injunctive relief or other equitable remedy from any court of competent
jurisdiction as may be necessary or appropriate to prevent or curtail any such
breach, threatened or actual. The foregoing shall be in addition to and without
prejudice to any other rights that the Company may have under this Agreement, at
law or in equity, including, without limitation, the right to sue for damages.

         8.3 No Rights in Contracts. Employee acknowledges and agrees that he or
she shall not have any rights in or to any contracts entered into with clients
or customers of the Company in connection with services provided by Employee
hereunder (including those in which Employee may be specifically named with the
Company), unless otherwise agreed to in writing by the Company.

         8.4 Assignment. The rights and obligations of the Company under this
Agreement shall inure to the benefit of and shall be binding upon the successors
and assigns of the Company. Employee's rights under this Agreement are not
assignable and any attempted assignment thereof shall be null and void.

         8.5 Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of Michigan without giving effect to the
conflict of law provisions thereof.

         8.6 Entire Agreement; Amendments. This Agreement constitutes the entire
agreement between the parties and supersedes all other agreements between the
parties which may relate to the subject matter contained in this Agreement. This
Agreement may not be amended or modified except by an agreement in writing which
refers to this Agreement and is signed by both parties.

         8.7 Headings. The headings of sections and subsections of this
Agreement are for convenience only and shall not in any way affect the
interpretation of any provision of this Agreement or of the Agreement itself.

         8.8 Severability. Whenever possible, each provision of this Agreement
shall be interpreted in such manner as to be effective and valid under
applicable law. If any provision of this Agreement shall be prohibited by or
invalid under applicable law, such provision shall be ineffective to the extent
of such prohibition or invalidity, without invalidating the remainder of such
provision or the remaining provisions of this Agreement.

         8.9 Waiver. The waiver by any party of a breach of any provision hereof
shall not be deemed to constitute the waiver of any prior or subsequent breach
of the same provision or any other provisions hereof. Further, the failure of
any party to insist upon strict adherence to any term of this Agreement on one
or more occasions shall not be considered a waiver or deprive that party of the
right thereafter to insist upon strict adherence to that term or any other term
of this Agreement unless such party expressly waives such provision pursuant to
a written instrument which refers to this Agreement and is signed by such party.

                            LEASE GUARANTY AGREEMENT



         THIS LEASE GUARANTY AGREEMENT (this "Agreement") is dated as of
______________________________, 19__, between ____________________________, a
__________________________ ("Landlord"), having its principal offices at
__________________________, and RUSH ENTERPRISES, INC., a Texas corporation
("Guarantor"), having its principal offices at 8810 I.H. 10 East, San Antonio,
Texas 78219.

                              W I T N E S S E T H:

         Contemporaneously herewith, Landlord, as landlord, is entering into a
certain Lease Agreement With Option to Purchase (the "Lease") for real property
located in the City of , County of , and State of Michigan, which property is
more particularly described in Exhibit A attached to the Lease, with Rush
Equipment Centers of Michigan, Inc., a Delaware corporation ("Tenant"), as
tenant. Guarantor owns a controlling interest in the capital stock of Tenant and
is executing this Agreement as an inducement to Landlord to enter into the
Lease.

         NOW THEREFORE, in consideration of the premises, Guarantor agrees as
follows:

1. Guarantor hereby absolutely and unconditionally guarantees to Landlord the
full and punctual payment by Tenant, its successors and assigns of all rent
required to be paid by Tenant under the Lease. This is a guaranty of payment
(and not merely collectability) only, and not a guaranty of the performance or
observance of any of the other covenants, obligations or duties of Tenant under
the Lease (other than Tenant's obligations to pay rent thereunder).

2. Guarantor hereby waives demand, protest, notice of any indulgences or
extensions granted to Tenant, any requirements of diligence or promptness on the
part of Landlord in the enforcement of the Lease and any notice thereof, and any
other notice whereby to charge Guarantor; provided however, Guarantor shall be
furnished with a copy of any notice of or relating to default under or
termination of the Lease to which Tenant is entitled or which is served upon
Tenant at the time the same is sent to or served upon Tenant.

3. The liability of Guarantor hereunder shall in no way be affected by: (a) the
release or discharge of Tenant in any creditors', receivership or bankruptcy
proceeding; (b) any alteration of or amendment to the Lease which alteration or
amendment has been consented to in writing by Guarantor; (c) any permitted sale,
assignment, or sublease, (unless Tenant is released by Landlord pursuant to any
such sale, assignment, or sublease), pledge or mortgage of the rights of Tenant
under the Lease; or (d) any application or release of any security or other
guaranty given for the performance and observance of the covenants and
conditions in the Lease on Tenant's part to be performed and observed.

4. This Agreement, and any obligations of Guarantor hereunder, shall terminate
upon the earlier of (a) the expiration of the primary term of the Lease
(including any extension or renewal periods) or (b) the termination of the Lease
for any reason other than a default by Tenant thereunder.



                                       1

5. This Agreement shall inure to the benefit of Landlord and its successors and
assigns and any assignee of Landlord's interest in the Lease, and shall be
binding upon Guarantor and its successors and assigns.

6. This Agreement may not be changed or terminated orally, but only by a written
amendment hereto signed by a duly authorized representative of Guarantor.

7. Any notice required hereunder to be sent to Guarantor shall be sufficiently
given by mailing by certified or registered mail, postage prepaid, addressed as
follows:

                            Rush Enterprises, Inc.

COUNTY OF ____________                 )


             SUBORDINATION, NONDISTURBANCE AND ATTORNMENT AGREEMENT


         THIS AGREEMENT is entered into by and between
_______________________________, a ________________________________ ("Lender"),
____________________________________, a ________________________________
("Landlord"), and Rush Equipment Centers of Michigan, Inc., a Delaware
corporation ("Tenant").

                                    Recitals

         Lender is the mortgagee under that certain ______________________
("Mortgage") dated ____________________, executed by Landlord, as grantor,
mortgaging certain real property ("Premises") located in ______________ County,
Michigan, more particularly described on EXHIBIT A attached hereto and made a
part hereof for all purposes.

         Tenant has a leasehold estate in and to the Premises pursuant to the
Lease Agreement ("Lease") of even date herewith, executed by Tenant and
Landlord.

         Lender, Landlord, and Tenant desire to enter into this Agreement to set
forth their agreement concerning the Lease and the Premises.

                                    Agreement

         In consideration of the covenants and agreements contained herein and
for other good and valuable consideration, the receipt and sufficiency of which
are hereby acknowledged, the parties agree as follows:

         1. The Lease, and the rights of Tenant in, to and under the Lease and
the Premises, are hereby subjected and subordinated to the lien of the Mortgage.

         2. So long as Tenant is not in default of any material terms or
provisions of the Lease (beyond any and all notice periods and periods given to
Tenant to cure any such defaults), Lender shall not disturb Tenant's possession
of the Premises or any of Tenant's other rights and privileges under the Lease,
and the Lease shall not be terminated (except as permitted by the provisions of
the Lease) or otherwise be diminished or adversely affected by the enforcement
of any rights given to Lender in the Mortgage, in the note secured thereby, or
in any other documents held by Lender or by the enforcement of any rights given
to Lender as a matter of law.

         3. Tenant shall attorn to Lender or to any person who acquires title to
the Premises through a foreclosure of the lien created by the Mortgage or by a
transfer in lieu of such foreclosure ("Purchaser"). Upon acquisition of title to
the Premises, Purchaser shall succeed to the interest of Landlord under the
Lease, and upon Tenant's receipt of notice from Purchaser,





                                       1
<PAGE>   77
together with a copy of the instrument of conveyance, Tenant shall accept
Purchaser as Tenant's new landlord, and the Lease shall continue in full force
and effect, after any such foreclosure or other transfer of title, as a direct
lease between Tenant and Purchaser, upon all the terms, covenants, conditions,
and agreements set forth in the Lease.

         4. Tenant acknowledges and consents to the assignment of Landlord's
rights under the Lease to Lender pursuant to the Mortgage which contains a
provision assigning to Lender all Leases, rents and other income from the
Premises.

         5. If the Mortgage is foreclosed and Lender succeeds to the interest of
Landlord under the Lease, Lender shall be bound to Tenant under all the terms,
covenants and conditions of the Lease. Notwithstanding the foregoing, however,
Lender shall not be (a) liable for any act or omission of Landlord or any prior
lessor, except to the extent the same constitutes a default existing and
continuing during Lender's ownership of the Premises; (b) subject to any offsets
or defenses that Tenant may have against Landlord or any prior lessor or subject
to any claim for damages or counterclaims against Landlord or any prior lessor;
(c) bound by any rent or additional rent that Tenant may have paid more than one
month in advance to Landlord or any prior lessor; (d) bound by any amendment or
modification of the Lease or any consent, approval or waiver by Landlord with
respect to the Lease or the Premises made after the date hereof without Lender's
prior written consent; (e) liable for any security deposit except to the extent
Lender does hold such security deposit; (f) liable to Tenant under the Lease or
otherwise for matters first arising after Lender ceases to own the Premises; (g)
liable for any covenant or agreement to undertake or complete construction or
installation of improvements on the Premises or any part thereof; (h) liable for
any payment to Tenant of any sums, or granting to Tenant of any credit, in the
nature of a contribution towards the cost of preparing, furnishing or moving in
to the Premises or any part thereof; or (i) liable for any other obligation
under the Lease which shall have accrued prior to the date Lender acquires title
to the Premises; provided, however, Lender shall be obligated to cure any
existing and continuing defaults of Landlord or any prior lessor with respect to
the maintenance or repair of the Premises. If Lender becomes liable to Tenant
under this paragraph for any claim, loss or damage, Tenant shall look solely to
the Premises for recovery of any judgment or damages from Lender, and Lender
shall have no personal liability, directly or indirectly, under or in connection
with the Lease. Nothing in this Agreement shall impose any obligation on Lender
for the management, control or condition of the Premises prior to the time
Lender succeeds to the interest of Landlord under the Lease.

         6. Landlord and Tenant will not, without the prior written consent of
Lender (which shall not be unreasonably withheld or delayed), (i) amend the
Lease, (ii) assign or sublet all or any part of the Premises unless permitted
under the express provisions of the Lease, or (iii) subordinate the Lease to any
other lien.

         7. In the event of the occurrence of any act or omission of Landlord
that would give Tenant the right to terminate the Lease, to claim a partial or
total eviction, or to exercise any other remedy under the Lease or other
applicable law, Tenant shall give to Lender copies of all written notices of
such act or omission that Tenant is required to give to Landlord pursuant to the
terms of the Lease, and Lender shall have the same period for remedying such act
or omission as granted to Landlord under the Lease.




                                       2

         8. Tenant hereby represents and warrants to Lender that as of the date
hereof:

            a. the Lease is in full force and effect;

            b. the Lease has not been modified or amended;

            c. all rents, additional rents and other sums due and payable under
               the Lease have been paid in full and no rent due under the Lease
               has been paid more than one (1) month in advance; and

            d. Tenant has not assigned, sublet, transferred or hypothecated its
               interest in the Lease.

         9. Tenant agrees, from time to time, upon ten (10) days' prior written
notice from Lender, to execute, acknowledge and deliver to Lender an estoppel
certificate in form reasonably satisfactory to Lender stating that the Lease is
then in effect, the rental then prevailing under the Lease and any defaults by
Landlord under the Lease of which Tenant is then aware.

         10. The foregoing provisions shall be self-operative and effective
without the execution of any further instruments on the part of any party
hereto. The parties, however, agree to execute and deliver to each other such
other instrument as shall be necessary to effectuate the provisions of this
Agreement.

         11. Any notice, request, demand, or other instrument which may be
required or permitted to be furnished to or served upon the parties shall be in
writing, shall be sent by United States mail, registered or certified, return
receipt requested, and shall be deemed given when postmarked and addressed to

     a.   Real property taxes and special assessments levied against the leased

     Requirements to carry on its business in the places and in the manner as

     carry on any of its businesses as now conducted or to own, lease or operate
     the Assets. Seller is qualified or otherwise authorized to do business as a

     former employees (or beneficiaries of them) of the Seller.

          (b) Representations. The consummation of this Agreement (and the
     employment by the Purchaser of former employees of the Seller) will not

     interest or any other claims resulting from any employee pension benefit
     plan, employee welfare benefit plan, or other employee benefit agreement or
     arrangement set out in Schedule 4.2(a). In addition, the Seller makes the

     liability as defined in Section 4201 of ERISA, and (ii) all group health
     plans maintained by Seller have been operated in compliance with Section
     4980B(f) of the Code.

All of such contracts, agreements, leases, licenses, plans, arrangements, and
commitments and all other such items included in the Assets but not specifically
described above (collectively, the "Contracts") are valid, binding and in full
force and effect in accordance with their terms and conditions and there is no
known existing default thereunder or breach thereof by Seller, or, to the Best
Knowledge of Seller, by any other party to the Contracts, or any conditions
which, with the passage of time or the giving of notice or both, might
constitute such a default by Seller, or, to the Best Knowledge of Seller, by any
other party to the Contracts, and the Contracts will not be breached by or give
any other party a right of termination as a result of the transactions
contemplated by this Agreement. Seller is not obligated to pay any liquidated
damages under any of the contracts, agreements, indentures, leases or other
instruments described in Schedule 4.8(a) hereto and Seller is not aware of any
facts or circumstances that could reasonably be expected to result in an
obligation of Seller to pay any such liquidated damages. To the Best Knowledge
of Seller there is no reason why any of the Contracts cannot readily be
fulfilled or performed by Purchaser with the Assets on time without undue or
unusual expenditure of money or effort. Copies of all of the documents (or in
the case of oral commitments, descriptions of the material terms thereof)
relevant to the Contracts listed in Schedule 4.8 have been delivered by Seller
to Purchaser, and such copies and/or descriptions are true, complete and
accurate and include all amendments, supplements or modifications thereto. After
reviewing the Contracts, Purchaser may, at its sole option, choose not to assume
one or more of the Contracts, and, within 30 days of receipt by Purchaser of all
information reasonably requested by Purchaser with respect to the Contracts,
Purchaser shall notify Seller of which Contracts, if any, Purchaser does not
intend to assume hereunder. Except for Contracts, if any, that Purchaser
notifies Seller that it will not assume, all of the Contracts are and shall be
included in the Assets. All of the Contracts may be assigned to Purchaser
without the approval or consent of any Person, or, if such approval or consent
is required, it will be obtained by Seller and delivered to Purchaser at or
prior to the Closing.

     4.9 Effect of Agreement. The execution and delivery of this Agreement and
the consummation of the transactions contemplated hereby will not (a) violate
any provision of the Articles of Incorporation or other charter documents or
bylaws of Seller; (b) result in any violation of any Governmental Requirement
applicable to Seller, the Assets or the Business; (c) conflict with, or result
in any breach of, or default or loss of any right under (or an event or
circumstance that, with notice or the lapse of time, or both, would result in a
default), or the creation of an Encumbrance pursuant to, or cause or permit the
acceleration prior to maturity or "put" right with respect to, any obligation
under, any contract, indenture, mortgage, deed of trust, lease, loan agreement
or other agreement or instrument to which Seller is a party or to which any of
the Assets are subject; (d) relieve any Person of any obligation (whether
contractual or otherwise) or enable any Person to accelerate or terminate any
such obligation or any right or benefit enjoyed by Seller or to exercise any
right under any agreement in respect of the Assets or the Business; and (e)
require notice to or the consent, authorization, approval, clearance, waiver or
order of any Person (except as may be contemplated by the last sentence of
Section 4.8). To the Best Knowledge of Seller, the business


                                       18
<PAGE>   27


relationships of clients, customers and suppliers of the Business will not be
adversely affected by the execution and delivery of this Agreement or the
consummation of the transactions contemplated hereby. The execution, delivery
and performance of this Agreement by Seller will not result in the loss of any
material governmental license, franchise or permit possessed by Seller.

     Notwithstanding the foregoing, Seller and Shareholder represent that there
are various dealer/distributor agreements with third parties other than John
Deere and, upon notice of sale, any one or more of such third parties may object
to the sale contemplated by this Agreement and further may terminate such
dealer/distributor agreements. Seller shall take all reasonable steps to
encourage the assignment of any such dealer/distributor agreements from Seller
to Purchaser; however, the withholding of consent to any such assignment shall
not be the basis of any claim of default or breach by Seller under this
Agreement.

Purchaser under Articles 10 and 17 to terminate this Agreement or refuse to
consummate the transactions contemplated hereby).

requirement for information under the Hart-Scott-Rodino Antitrust Improvements
Act of 1976 or to comply with any requested divestiture of assets or to enter
into any consent or similar order or agreement shall not constitute a failure of
Purchaser to use commercially reasonable efforts), and (d) deliver to Seller at
the Closing the certificate contemplated by Article 11 (with such additions or
exceptions to such certificate as are necessary to make the statements set forth
in such certificate accurate, provided that if any of such additions or

Agreement or to refuse to consummate the transactions contemplated hereby).

which may now or in the future be paid, incurred or suffered by or asserted
against such party arising out of or resulting from or relating to any Taxes or
Tax Returns of Seller for any period, or portion thereof, up to and including
the Closing Date (collectively, "Tax Losses").

Location, the presence or use of Hazardous Materials at the New Pontiac
Location, or any Environmental Condition at the New Pontiac Location, first
arising after the Closing Date and not attributable to Seller, Shareholder or
Seller's affiliates or any of their respective agents, employees or
representatives.

     13.6 Procedure. All claims for indemnification or payment under this
Article shall be asserted and resolved as follows:

          (a) An Indemnitee shall promptly give the Indemnitor written notice of
     any matter which an Indemnitee has determined has given or could give rise
     to a right of indemnification under this Agreement (an "Indemnification
     Event"), stating the amount of the Loss, if known, and method of
     computation thereof, all with reasonable particularity, and stating with
     particularity the nature of such matter. Failure to provide such written
     notice shall not affect the right of the Indemnitee to indemnification
     except to the extent such failure shall have


                                       34
<PAGE>   43


     resulted in liability to the Indemnitor that could have been actually
     avoided had such notice been provided within such required time period.

          (b) The obligations and liabilities of an Indemnitor under this
     Article with respect to Losses arising from claims of any third party that
     are subject to the indemnification provided for in this Article
     ("Third-Party Claims") shall be governed by and contingent upon the
     following additional terms and conditions: if an Indemnitee shall receive
     notice of any Third-Party Claim, the Indemnitee shall give the Indemnitor
     prompt notice of such Third- Party Claim and the Indemnitor may, at its
     option, assume and control the defense of such Third-Party Claim at the
     Indemnitor's expense and through counsel of the Indemnitor's choice
     reasonably acceptable to Indemnitee. Subject to the condition that written
     notice be delivered prior to the expiration of one year after the Closing
     Date, failure to provide such written notice shall not affect the right of
     the Indemnitee to indemnification except to the extent such failure shall
     have resulted in liability to the Indemnitor that could have been actually
     avoided had such notice been provided within such required time period. In
     the event the Indemnitor assumes the defense against any such Third-Party
     Claim as provided above, the Indemnitee shall have the right to participate
     at its own expense in the defense of such asserted liability, shall
     cooperate with the Indemnitor in such defense and will attempt to make
     available on a reasonable basis to the Indemnitor all witnesses, pertinent
     records, materials and information in its possession or under its control
     relating thereto as is reasonably required by the Indemnitor. In the event
     the Indemnitor does not elect to conduct the defense against any such
     Third-Party Claim, the Indemnitor shall cooperate with the Indemnitee (and
     be entitled to participate) in such defense and attempt to make available
     to it on a reasonable basis all such witnesses, records, materials and
     information in its possession or under its control relating thereto as is
     reasonably required by the Indemnitee. The Indemnitor understands that if
     such Third-Party Claim results in an obligation to indemnify hereunder,
     Damages shall include all reasonable costs and expenses of such defense.
     Except for the settlement of a Third-Party Claim that involves the payment
     of money only and for which the Indemnitor has provided written objection
     to Indemnitee under Section 13.6(c), no Third-Party Claim may be settled
     without the written consent of the Indemnitee. Written notice of any
     proposed settlement of any such claim and the material terms thereof shall
     be delivered by Indemnitee to Indemnitor at least five Business Days prior
     to any settlement of any such claim.

          (c) If a claim for indemnity is provided pursuant to this Article by
     an Indemnitee and the Indemnitor does not pay such claim or object to such
     claim within 20 Business Days after written notice is received by the
     Indemnitor, such claim shall be deemed agreed to by the Indemnitor. If the
     Indemnitor shall object to such claim, a written notice of such objection
     setting forth in reasonable detail the basis for such objection shall be
     provided to the Indemnitee and such dispute shall be resolved in accordance
     with Section 24.12 hereof. In addition, if the claim shall have been
     determined to have been a valid claim, Damages shall include interest at
     the prime rate as quoted from time to time by The Frost National Bank from
     the date the claim is first made until fully paid.


                                       35
<PAGE>   44


     13.7 Payment. Payment of any amounts due pursuant to this Article shall be
made within ten Business Days after final adjudication of such claim and after
written notice is sent by the Indemnitee.

     13.8 Failure to Pay Indemnification. If and to the extent the Indemnitee
shall make written demand upon the Indemnitor for indemnification pursuant to
this Article and the Indemnitor shall refuse or fail to pay in full within
thirty (30) Business Days of such written demand the amounts demanded pursuant
hereto and in accordance herewith, then the Indemnitee shall proceed in
accordance with the arbitration provisions of Section 24.12 hereof; provided,
however, that in the case of indemnification for a Third-Party Claim, such
matter need not be resolved by arbitration until the underlying Third-Party
Claim is finally resolved.

     13.9 Cooperation. The Indemnitor and the Indemnitee shall cooperate with
each other with regard to any indemnification obligation under this Article and
each shall attempt to make available to the other on a reasonable basis all
personnel records, materials and information in its possession or under its
control as is reasonably requested by the other.

     13.10 Time Limitations. Notwithstanding any provision contained herein to
the contrary, Shareholder will have no liability with respect to any
representation, warranty, covenant or obligation, other than those set forth in
Section 13.11, Section 14 or in which actual fraud is involved, unless on or
before one (1) year from the Closing Date, Purchaser notifies Seller of a claim
specifying the factual basis of such claim in reasonable detail to the extent
then known by Purchaser.

     13.11 Special Provisions Concerning New Pontiac Location. The Rush Parties
and Seller agree to obtain a Phase I environmental site assessment of the New
Pontiac Location at the time that Purchaser enters into the lease therefor (and
Seller enters into the sublease therefor, as provided in Section 8.2(n) hereof,
and to obtain an update thereof as of the time that the sublease from Purchaser
to Seller terminates, in order to better establish the nature and extent of any
Environmental Conditions or violations of Environmental Laws occurring at or
with respect to the New Pontiac Location during Seller's occupancy thereof. Such
site assessment and the update thereof shall be prepared by a qualified
environmental consultant or firm selected and paid for by Purchaser and
reasonably acceptable to Seller. Seller agrees that one such firm is GeoConsul
of Buda, Texas. All reports prepared by such consultant or firm shall be the
property of Purchaser, but Purchaser shall provide Seller with copies thereof,
which Seller agrees to maintain in strict confidence in accordance with its
provision of Article 15 hereof. Notwithstanding anything in this Section 13.11
to the contrary, any environmental study shall be at the sole expense of the
Purchaser.

     13.12 Limitation on Indemnification. Notwithstanding any provision
contained herein to the contrary, the Rush Parties shall not make any claim for
indemnification, nor shall Seller or Shareholder be responsible for paying any
indemnification obligation, in excess of the Purchase Price.

     14. NON-COMPETITION AGREEMENTS.

     14.1 Non-Competition. In consideration of the benefits of this Agreement to
Seller and as a material inducement to the Rush Parties to enter into this
Agreement and pay the Purchase Price, Seller and Shareholder hereby covenant and
agree that, commencing on the Closing Date and ending


                                       36
<PAGE>   45


on the fifth anniversary of the Closing Date, Seller and Shareholder shall not,
and Seller will cause their Affiliates, officers, directors and representatives,
as applicable, not to, directly or indirectly, as proprietor, partner,
stockholder, director, executive, officer, employee, consultant, joint venturer,
investor or in any other capacity, engage in, or own, manage, operate or
control, or participate in the ownership, management, operation or control, of
any entity in the states of Michigan or Texas which engages in any business
activity which Seller or the Rush Parties or their Affiliates participates or
participated as of the Closing Date, including, but not limited to, the
construction machinery business; provided, however, the foregoing shall not
prohibit Seller and Shareholder, and their Associates, Affiliates and
representatives from purchasing and holding as an investment not more than 5% of
any class of publicly traded securities of any entity which conducts a business
in competition with the business of the Rush Parties, so long as Seller and
Shareholder, and their Affiliates and representatives do not participate in any
way in the management, operation or control of such entity.

     14.2 Judicial Reformation. Seller and Shareholder acknowledge that, given
the nature of the Rush Parties' business, the covenants contained in Section
14.1 establish reasonable limitations as to time, geographic area and scope of
activity to be restrained and do not impose a greater restraint than is
reasonably necessary to protect and preserve the goodwill of the Rush Parties'
business and to protect their legitimate business interests. If, however,
Section 14.1 is determined by any court of competent jurisdiction to be
unenforceable by reason of its extending for too long a period of time or over
too large a geographic area or by reason of it being too extensive in any other
respect or for any other reason, it will be interpreted to extend only over the
longest period of time for which it may be enforceable and/or over the largest
geographic area as to which it may be enforceable and/or to the maximum extent
in all other aspects as to which it may be enforceable, all as determined by
such court.

     14.3 Customer Lists; Non-Solicitation. Seller and Shareholder hereby
further covenant and agree that they shall not, and Seller and Shareholder will
cause their Affiliates and representatives not to, directly or indirectly, (a)
use or make known to any person or entity the names or addresses of any clients
or customers of Seller or the Rush Parties or any other information pertaining
to them, provided, however, such limitation shall not apply to any information
which (i) is then generally known to the public; (ii) become or becomes
generally known to the public through no fault of Seller or Shareholder, its
Affiliates and representatives, and (iii) is disclosed in accordance with an
order of a court of competent jurisdiction or applicable law, (b) call on,
solicit, or attempt to call on or solicit any clients or customers of Seller or
the Rush Parties, nor (c) solicit for employment, recruit, hire or attempt to
recruit or hire any employees of Seller or the Rush Parties.

     14.4 Covenants Independent. The covenants of Seller and Shareholder
contained in Sections 14.1, 14.2 and 14.3 of this Agreement will be construed as
independent of any other provision in this Agreement, and the existence of any
claim or cause of action by Seller or the Shareholder against the Rush Parties
will not constitute a defense to the enforcement by the Rush Parties of said
provisions. Seller and Shareholder understand that the provisions contained in
Sections 14.1, 14.2 and 14.3 are essential elements of the transactions
contemplated by this Agreement and, but for the agreement of Seller and
Shareholder to Sections 14.1, 14.2 and 14.3, the Rush Parties would not have
agreed to enter into this Agreement and the transactions contemplated herein.
Seller and Shareholder have been advised to consult with counsel in order to be
informed in all respects concerning the reasonableness and propriety of Sections
14.1, 14.2 and 14.3 with specific


                                       37
<PAGE>   46


regard to the nature of the business conducted by Seller and the Rush Parties,
Seller and Shareholder acknowledge that Sections 14.1, 14.2 and 14.3 are
reasonable in all respects.

     14.5 Remedies. In the event of a breach or a threatened breach by Seller or
the Shareholder of any of the provisions contained in Sections 14.1, 14.2 or
14.3 of this Agreement, Seller and Shareholder acknowledge that the Rush Parties
will suffer irreparable damage or injury not fully compensable by money damages,
or the exact amount of which may be impossible to obtain, and, therefore, will
not have an adequate remedy available at law. Accordingly, the Rush Parties
shall be entitled to obtain such injunctive relief or other equitable remedy,
without the necessity of posting bond therefor, from any court of competent
jurisdiction as may be necessary or appropriate to prevent or curtail any such
breach, threatened or actual. The foregoing shall be in addition to and without
prejudice to any other rights that the Rush Parties may have under this
Agreement, at law or in equity, including, without limitation, the right to sue
for damages.

     15. NON-DISCLOSURE OF CONFIDENTIAL INFORMATION.

     15.1 Covenant of Seller and Shareholder. Seller and Shareholder recognize
and acknowledge that they have and will have access to certain confidential
information of Seller that is included in the Assets (including, but not limited
to, environmental studies and reports, lists of customers, trade secrets, costs
and financial information) that after the consummation of the transactions
contemplated hereby will be valuable, special and unique property of Purchaser.
Seller and Shareholder agree that Seller and Shareholder will, and will cause
their Affiliates and representatives to, keep confidential and not disclose to
any other Person or use for his or its own benefit or for the benefit of any
other Person, and Seller and Shareholder will use their best efforts to prevent
disclosure by any other Person of, any such confidential information to any
Person for any purpose or reason whatsoever, except to authorized
representatives of Purchaser; provided, however, such limitation shall not apply
to any information which (a) is then generally known to the public, (b) become
or becomes generally known to the public through no fault of Seller or the
Shareholder, or Seller's Affiliates and representatives, and (c) is disclosed in
accordance with an order of a court of competent jurisdiction or applicable law.
In the event of a breach or a threatened breach by Seller or the Shareholder of
any of the provisions contained in this Article, Seller and Shareholder
acknowledge that the Rush Parties will suffer irreparable damage or injury not
fully compensable by money damages, or the exact amount of which may be
impossible to obtain, and, therefore, will not have an adequate remedy available
at law. Accordingly, the Rush Parties shall be entitled to obtain such
injunctive relief or other equitable remedy, without the necessity of posting
bond therefor, from any court of competent jurisdiction as may be necessary or
appropriate to prevent or curtail any such breach, threatened or actual. The
foregoing shall be in addition to and without prejudice to any other rights that
the Rush Parties may have under this Agreement, at law or in equity, including,
without limitation, the right to sue for damages.

     15.2 Covenant of Rush Parties. Rush and Rush Parties, their officers,
directors, agents, employees and any Affiliate of Rush and Rush Parties (for
purposes of this Section 15.2, collectively, the "Purchaser"), recognize and
acknowledge that they have and will have access to certain confidential
information of Seller that is included in the Assets (including, but not limited
to, environmental studies and reports, lists of customers, trade secrets, costs
and financial information) that is valuable, special and unique property of
Seller. In the event the transactions


                                       38
<PAGE>   47


contemplated hereby are not consummated, Purchaser agrees that Purchaser will,
and will cause Purchaser's Affiliates and representatives to, keep confidential
and not disclose to any other Person or use for his or its own benefit or for
the benefit of any other Person, and Purchaser will use their best efforts to
prevent disclosure by any other Person of, any such confidential information to
any Person for any purpose or reason whatsoever, except to authorized
representatives of Seller; provided, however, such limitation shall not apply to
any information which (a) is then generally known to the public, (b) become or
becomes generally known to the public through no fault of Purchaser and
Purchaser's representatives, and (c) is disclosed in accordance with an order of
a court of competent jurisdiction or applicable law. In the event of a breach or
a threatened breach by Purchaser of any of the provisions contained in this
Article, Purchaser acknowledges that Seller and Shareholder will suffer
irreparable damage or injury not fully compensable by money damages, or the
exact amount of which may be impossible to obtain, and, therefore, will not have
an adequate remedy available at law. Accordingly, Seller and Shareholder shall
be entitled to obtain such injunctive relief or other equitable remedy, without
the necessity of posting bond therefor, from any court of competent jurisdiction
as may be necessary or appropriate to prevent or curtail any such breach,
threatened or actual. The foregoing shall be in addition to and without
prejudice to any other rights that Seller and Shareholder may have under this
Agreement, at law or in equity, including, without limitation, the right to sue
for damages.

     16. DAMAGE TO ASSETS. If, on or before the Closing Date, any of the Assets
are damaged or destroyed, Seller will immediately notify Purchaser of such
damage or destruction. In the event of any such damage or destruction, Purchaser
shall (a) remove any or all of the damaged or destroyed asset or assets it does
not desire to purchase from the Assets to be purchased hereunder and reduce the
Purchase Price by an amount equal to the portion of the Purchase Price
attributable to the damaged or destroyed asset or assets so removed and (b)
complete the purchase of the remainder of the Assets and reduce the Purchase
Price by the loss in fair market value of any damaged or destroyed Assets that
are purchased by Purchaser.

     17. TERMINATION. This Agreement may be terminated without further
obligation of the parties, as follows:

     17.1 Mutual Consent. This Agreement may be terminated at any time prior to
Closing by mutual written consent of the parties hereto.

     17.2 Failure of Conditions. This Agreement may be terminated by any party
hereto, if the conditions, as set forth in this Agreement, to such party's
obligations under this Agreement are not fulfilled on or prior to the Closing
Date; provided that any such termination shall not limit the remedies otherwise
available to such party as a result of misrepresentations of or breaches by the
other party.

     17.3 Failure to Close. This Agreement will automatically terminate on
October 31, 1999, if the Closing shall not have occurred on or before such date,
unless the parties shall have otherwise agreed in writing prior to such date. No
party will be liable in damages to any other party as a result of termination
pursuant to this Section unless the failure of the Closing was due to the
failure of such party to comply with the terms of this Agreement.


                                       39
<PAGE>   48


     17.4 Liquidated Damages. The parties agree that in the event the Closing
does not occur due to the failure of Purchaser to comply with the terms of this
Agreement, the actual damages that might be sustained by Seller and Shareholder
are uncertain and difficult, if not impossible, to ascertain. Therefore, the
parties agree that upon such failure to close Purchaser shall pay to Seller the
Escrowed Funds as liquidated damages. The parties agree that the payment of such
amount as liquidated damages represents the parties' reasonable forecast of
fair, reasonable and just compensation for Purchaser's failure to comply with
the terms of this Agreement.

     18. SPECIAL PROVISIONS REGARDING EMPLOYEES OF SELLER.

     18.1 New Employees of Purchaser. It is the intention of Purchaser, and
Seller hereby acknowledges and agrees with such position, that any employees of
Seller that Purchaser hires will be new employees of Purchaser as of the Closing
Date or the date of hire, whichever is later. Such new employees shall be
entitled only to such compensation and employee benefits as are agreed to by
such employees and Purchaser, or as are otherwise provided by Purchaser, in its
sole discretion.

     18.2 No Hiring Commitment. Purchaser specifically does not commit to hire
any of the employees of the Business, and Seller specifically understands and
acknowledges this fact. However, notwithstanding Purchaser's position, Purchaser
will review its needs in anticipation of the purchase of the Assets with a view
to hiring certain of the employees of Seller as of the Closing Date. In its
review, Purchaser expects to be able to review employee records and conduct
employee interviews. Seller agrees that after the date hereof it will make, on a
confidential basis, its employee records available to Purchaser and permit
Purchaser to contact its employees for the purpose of conducting employee
interviews. Seller further agrees to make employees designated by Purchaser
available to Purchaser for such purpose.

     18.3 Vacation, Sick Pay, Health Insurance, etc.

          (a) Notwithstanding Purchaser's decision to hire any or all of such
     employees after the Closing Date, Purchaser shall not be liable under any
     bonus plan or other plan described in Schedule 4.2(a) or under any other
     similar plan that may have been established by Seller or for any health
     insurance benefits that may have accrued to such employees prior to the
     Closing Date, and Seller expressly acknowledges that it has sole liability
     for all such employee benefit costs accrued as of the Closing Date whether
     or not any or all of such employees are subsequently hired by Purchaser
     pursuant to Section 18.1. Notwithstanding the foregoing, Purchase shall
     assume at the Closing Seller's obligations to employees of Seller actually
     hired by Purchaser for accrued but unused vacation and sick leave, which
     shall include (i) accrued vacation and sick leave through each employee's
     previous anniversary date and (ii) the pro rata portion of vacation and
     sick leave earned by each employee since the last anniversary date through
     the Closing Date, which such vacation and sick leave will be available to
     employee following his next anniversary, and the Purchase Price shall be
     reduced by the dollar value of such obligation; provided, however,
     Purchaser shall only assume up to the number of accrued but unused vacation
     and sick leave days that each employee of Seller actually hired by
     Purchaser would be entitled to under Purchaser's vacation day and sick
     leave policy. Except for vacation and sick leave time assumed by Purchaser
     as set forth above, Purchaser


                                       40
<PAGE>   49


     shall have no obligation after the Closing to continue any pension plans or
     work benefit plans currently offered by Seller to its employees.

          (b) With respect to employees actually employed by Purchaser, Seller
     will remain responsible for medical expenses covered under its plans (i)
     actually incurred prior to the Closing Date or (ii) actually incurred with
     respect to any hospitalization that begins prior to the Closing Date until
     such hospitalization ends (as required under such plans), and Purchaser
     will be responsible for all other medical expenses incurred on or after the
     Closing Date to the extent covered under its plans; provided, however, the
     employees will be treated as newly hired employees of Purchaser beginning
     on the Closing Date insofar as medical expenses paid under Purchaser's
     plans affects the time or amount of coverage. Seller shall cooperate with
     Purchaser to provide continuity of such insurance coverage to such
     employees. Seller shall be solely responsible for any obligations under the
     Consolidated Omnibus Budget Reconciliation Act, as amended, with respect to
     its employees.

     18.4 Severance Benefits; Employment Termination. Purchaser shall have no
obligation whatsoever to pay all or any part of any severance benefits that
Seller is or may be obligated to pay in connection with the termination of
employment by Seller of any of its employees.

     18.5 Employee Benefit Plans. Purchaser shall not and does not hereby
assume, continue or maintain any pension, retirement or welfare plans, severance
or vacation policies or benefits, or other employee compensation or benefit
arrangements or policies or plans maintained by Seller for its employees. It is
intended that Purchaser shall not at any time be a successor employer for
purposes of Title IV of the Employee Retirement Income Security Act of 1974, as
amended ("ERISA"). Seller hereby represents and warrants to Purchaser that the
consummation of this Agreement (and the employment by the Purchaser of former
employees of the Seller) will not result in any carryover liability to the
Purchaser for taxes, penalties, interest or any other claims resulting from any
employee pension benefit plan, employee welfare benefit plan, or other employee
benefit agreement or arrangement maintained by Seller. In addition, the Seller
makes the following representations (a) as to employee pension benefit plans of
Seller: (i) Seller has not become liable to the PBGC under Section 4062, 4063 or
4064 of ERISA under which a lien could attach to the assets of the Seller under
Section 4068 of ERISA; (ii) Seller has not ceased operations at a facility so as
to become subject to the provisions of Section 4062(e) of ERISA; and (iii)
Seller has not made a complete or partial withdrawal from a multiemployer plan
(as defined in Section 3(37) of ERISA) so as to incur withdrawal liability as
defined in Section 4201 of ERISA, and (b) all group health plans maintained by
Seller have been operated in compliance with Section 4980B(f) of the Code. In
addition, the parties agree that the Purchaser does not and will not assume the
sponsorship of, or the responsibility for contributions to, or any liability in
connection with, any employee pension benefit plan, any employee welfare benefit
plan, or other employee benefit agreement or arrangement maintained by Seller
for its employees, former employees, retirees, their beneficiaries or any other
person. In addition and not as a limitation of the foregoing covenant, the
parties agree that the Seller shall be liable for any continuation coverage
(including any penalties, excise taxes or interest resulting from the failure to
provide continuation coverage) required by Section 4980B of the Code due to
qualifying events which occur on or before Closing Date.

     18.6 Reporting of Data. Purchaser and Seller shall complete and furnish to
each other such other employee data as shall be reasonably required from time to
time for each party to perform and fulfill its obligations under this Article.

     18.7 Employment Related Claims. Seller agrees that it, and not Purchaser,
shall be solely responsible for, and Seller hereby agrees to indemnify, defend
and hold harmless Purchaser from and against, all liability, costs and expenses
(including reasonable attorneys' fees) for all existing employment claims that
have been filed by any employee or former employee of Seller prior to the
Closing Date relating to arbitrations, unfair labor practice charges, employment
discrimination charges, wrongful termination claims, workers' compensation
claims, any employment-related tort claim or other claims or charges of or by
employees of Seller, or any thereof filed after the Closing Date but arising as
a result of conditions, actions or events or series of actions or events which
occurred prior to the Closing Date. Schedule 18.7 hereto sets forth a brief
description of any of such claims that have been filed or, to Seller's
knowledge, threatened. Without in any way limiting the foregoing, Seller shall
defend and hold harmless Purchaser from and against any and all claims, demands,
actions, judgments, costs and expenses, including without limitation, attorney
fees and settlement costs and other reasonable expenses, related to all
liabilities and obligations in connection with Seller's qualified pension,
retirement or welfare plans, severance or vacation policies or benefits, or
other employee compensation or benefit arrangements or policies.

     19. OFFSET PROVISIONS. Notwithstanding any other provisions of this
Agreement, in the event Seller or Shareholder become obligated to pay sums to
Purchaser or any party entitled to indemnification under this Agreement or any
of the documents or agreements referenced herein or contemplated hereby (whether
as a result of indemnity, breach of contract or otherwise), Purchaser shall be
entitled to, and shall have the right to, reduce and offset payments due under
this Agreement or the Mt. Morris Lease in such amount or amounts as Purchaser
(and any Indemnitee that is not promptly paid by Seller) is entitled to receive
from Seller or Shareholder, and any such offset shall be deemed to be a payment
under this Agreement.

     20. ADJUSTMENT OF PURCHASE PRICE. The Purchase Price shall be adjusted on
the Closing Date (a) to reduce the Purchase Price by the amount allocated to any
damaged or destroyed Assets as contemplated by Article 16; (b) to account for a
proration of personal property taxes on the Assets, lease payments, utilities
and other items commonly prorated; and (c) to account for any Deposits held by
Seller on the Closing Date. Three days prior to the Closing Date, Seller will
provide Purchaser with a statement of adjustments showing all proposed
adjustments to the Purchase Price, such statement of adjustments having all
reasonable backup documentation for such suggested adjustments. Purchaser and
Seller will work to finalize all required adjustments prior to the Closing Date.

     21. SURVEY.

     21.1 Survey. Upon written request by Purchaser within ten days from and
after the date hereof, Seller agrees, on behalf of Purchaser, and at Purchaser's
sole cost and expense, (a) to cause a registered, licensed state surveyor
approved by Purchaser and the Title Company to prepare a new or updated on the
ground survey of the Mt. Morris Land (the "Survey"), and (b) to deliver to
Purchaser at least three copies, to Purchaser's counsel at least one copy, and
to the Title Company


                                       42
<PAGE>   51


at least one copy of the Survey plat and a certificate under the seal of the
surveyor, which shall be made in accordance with the "Minimum Standard Detail
Requirements for ALTA/ACSM Land Title Surveys" jointly adopted by the American
Land Title Association and the American Congress on Surveying and Mapping in
1992, including items 1, 2, 3, 4, 6, 7, 8, 9, 10, 11 and 13 thereof. The Survey
shall also include the surveyor's registered number and seal, the date of the
Survey (which shall be no earlier than the date hereof), and the following
narrative certificate:

     "The undersigned does hereby certify that (i) this survey was this day made
     upon the ground of the property reflected hereon, for the benefit of and
     reliance by Rush Equipment Centers of Michigan, Inc., Rush Enterprises,
     Inc. and Cislo Title Company, (ii) the description contained hereon is
     correct, (iii) the property described hereon has separate access to and
     from a dedicated roadway as shown hereon, (iv) except as shown hereon,
     there are no discrepancies, conflicts, shortages in area, encroachments,
     improvements, overlapping of improvements, set-back lines, easements or
     roadways, (v) the gross and net areas (both acreage and square footage) of
     the property shown hereon are correct, and (vi) the area of the property is
     shown, if any, which lies within the one hundred year (100) year plain or
     any area having special flood hazards as designated by the U.S. Army Corps
     of Engineers, the Federal Emergency Management Agency, or any other
     government agency."

     The Survey shall be in form and substance acceptable to the Title Company
as a basis for deleting to the maximum extent permitted by applicable title
insurance regulations (at Seller's expense) the standard printed exceptions from
the Leasehold Policy of Title Insurance to be delivered by Seller as provided
below. The terms "net acreage" and "net square footage" as used herein shall
mean the number of acres and square feet determined by the surveyor to be equal
to (a) the total acreage and square footage within the surveyed parcel, less (b)
the number of total acres and square feet contained within any land lying within
any easement or right-of-way or other such matter as described in Subsections
(iv), (v) and (vi) above, and contained within any land lying within the 100
year flood plain. For purposes of the property description to be included in the
Mt. Morris Lease, the field notes prepared by the surveyor shall control any
conflicts or inconsistencies with the description herein. Without in any way
limiting the foregoing, the surveyor shall provide separate written field note
descriptions for each parcel comprising the Mt. Morris Land.

     21.2 Remedies for Failure to Deliver Survey. In the event Seller does not
deliver the Surveys within such ten-day period, then and thereafter, Purchaser
shall have the option to (a) cancel this Agreement, in which event the parties
hereto shall have no further obligations hereunder, or (b) procure the Survey,
at the expense of Seller (and Seller shall reimburse Purchaser immediately upon
demand for all amounts incurred or expended in procuring the same, and in the
event Seller does not so reimburse Purchaser, Purchaser may deduct such amounts
from the Purchase Price on the Closing Date), or (c) waive the Survey
requirements and proceed to close the transactions contemplated by this
Agreement.

     22. TITLE COMMITMENT AND CONDITION OF TITLE.

     22.1 Title Commitment. Within ten days from and after the date hereof, at
Purchaser's sole cost and expense, Seller for the benefit of Purchaser agrees to
cause the Title Company to furnish


                                       43
<PAGE>   52


Purchaser and its counsel a Commitment for Leasehold Owner Policy of Title
Insurance (the "Title Commitment") prepared and issued by the Title Company
describing and covering the Mt. Morris Land listing Purchaser as the prospective
named insured and showing as the policy amount $400,000. The Title Commitment
shall constitute the commitment of the Title Company to insure, by title
insurance in the standard form promulgated in the State of Michigan, Purchaser's
leasehold interest in the Mt. Morris Land subject only to the exceptions set
forth in the Title Commitment and to the standard printed exceptions except as
modified below, but deleting (at Purchaser's expense in excess of the expense of
a standard policy with exceptions) to the maximum extent permitted by applicable
title insurance regulations the standard printed form survey exception. The
standard exception as to the lien for taxes shall be limited to the year of
Closing, and shall be endorsed "Not Yet Due and Payable." The Title Commitments
shall contain no exception for "visible and apparent easements" or for "public
or private roads" or the like. The Title Commitments shall contain no exception
for "rights of parties in possession" (other than Purchaser). In addition, the
Title Commitment shall provide (by endorsements or otherwise as permissible
under applicable regulations) coverage against violation of restrictive
covenants and zoning laws, encroachments, overlapping of improvements, shortages
in area and mechanic's liens.

     22.2 Disclosure of Exceptions by Title Commitment and UCC Report. Purchaser
shall have a period of 20 days from the last to be delivered to Purchaser and
its counsel of each of the Survey, UCC Report, Title Commitment and the
documents referred to therein as conditions or exceptions to title in which to
review such items and to deliver to Seller in writing such objections as
Purchaser may have to anything contained or set forth in the Survey, UCC Report,
Title Commitment or title exception documents. Any items to which Purchaser does
not object within such period shall be deemed to be permitted exceptions
hereunder ("Permitted Exceptions"). In the event Purchaser timely objects to any
matter contained in the Survey, UCC Report, Title Commitment or title exception
documents, Seller shall have a reasonable time, not to exceed fifteen days from
the date such objections are made known in writing to Seller, to cure such
objections. Any curative actions shall be completed and all curative materials
shall be filed by Seller, at its sole cost and expense, within such 15-day
period. If Seller cannot cure the objections within such fifteen- day period,
Purchaser shall have the option to (a) cancel this Agreement, in which event the
parties shall have no further obligations hereunder; (b) if the matters to which
Purchaser has objected can be cured for $50,000 or less (subject to the consent
of the owner of the applicable parcel), to cure and deduct the cost of such cure
from the Purchase Price; or (c) waive the objections, and proceed to close the
transaction contemplated hereby in which event such objections shall be included
as exceptions to title in the Mt. Morris Lease. In the event, however, that a
lien indebtedness against the Mt. Morris Property (including past due taxes) is
disclosed by the applicable Title Commitment or UCC Report, then Seller shall
(y) discharge such lien indebtedness prior to the Closing, or (z) authorize the
Title Company to discharge such lien indebtedness at the Closing out of the
Purchase Price, and all costs incurred in connection with discharging such lien
indebtedness shall not count against the $50,000 amount referenced in clause (b)
of the immediately preceding sentence.

     23. ENVIRONMENTAL STUDIES AND REMEDIATION ACTIVITIES.

     23.1 Environmental Studies. Within 10 days after the date hereof, Seller
shall provide to Purchaser, at Seller's cost and expense, copies of (a) all
existing Environmental Site Assessments (whether Phase I, Phase II or otherwise)
covering all or any portion of the Mt. Morris Land, to the


                                       44
<PAGE>   53


extent the same are in Seller's possession or Seller has access to them, and (b)
any other environmental studies, reports and information, including, without
limitation, correspondence from Governmental Authorities, concerning the
environmental condition of the Mt. Morris Land, to the extent the same are in
Seller's possession or Seller has access to them (all of the foregoing
information, whether obtained by Purchaser or provided by Seller, being
hereinafter referred to as "Environmental Information"). At Purchaser's option
(x) Purchaser may obtain new or updated Environmental Site Assessments for the
Mt. Morris Land certified to Purchaser so that Purchaser may rely on same,
and/or (y) a recertification of the existing Environmental Site Assessments to
Purchaser, and/or (z) Phase II Environmental Site Assessments certified to both
Seller and Purchaser. Without in any way limiting the provisions of the
preceding sentence, Purchaser and its contractors and representatives, at
Purchaser's expense, shall have at least sixty (60) days from the date hereof
(the "Feasibility Period") within which to conduct any and all engineering,
environmental and economic feasibility studies and tests of the Mt. Morris Land
which Purchaser, in Purchaser's sole discretion, deems necessary to determine
whether the Real Property is environmentally, engineeringly and economically
suitable for Purchaser's intended use. In accordance with Section 8.6 hereof,
Seller has granted and hereby grants to Purchaser and its contractors and
representatives access to the Mt. Morris Land for the purpose of performing such
studies or tests. Such persons shall conduct their studies and tests in such a
manner as to minimize interference with the Business, and, upon completion of
their activities on the Mt. Morris Land shall restore each parcel of real
property as nearly as is reasonably possible to the condition it was in
immediately prior to such activities.

     23.2 Remediation. In the event that any of the Environmental Information or
any studies or tests performed or commissioned by Purchaser indicate the
existence of any Environmental Conditions on the Mt. Morris Land, then Seller
shall have a period of 30 days after notification thereof in which to remediate
or otherwise cure the same in accordance with all applicable Governmental
Requirements or to give notice in writing to Purchaser, that it will not
undertake such remediation. In the event that an Environmental Condition exists
or is discovered on the Mt. Morris Land and Seller fails or refuses to remediate
or otherwise cure such Environmental Condition within the required 30-day
period, or in the event such Environmental Condition is not capable of being
remediated or otherwise cured within such 30-day period, then Purchaser shall
have the following options: (a) cancel this Agreement by written notice thereof
given to Seller prior to the Closing Date, in which event the parties hereto
shall have no further obligations hereunder, (b) if the Environmental Condition
can be remediated or cured for $50,000 or less, to remediate or cure and deduct
the cost of such cure from the Purchase Price; (c) if the Environmental
Conditions affect a portion, but not all, of the Mt. Morris Land, to elect to
delete the portion of the real property so affected from the definition of "Mt.
Morris Land" hereunder and to lease only the newly defined "Mt. Morris Land" at
Closing, or (d) waive in writing the remediation or cure of such Environmental
Condition (without in any way waiving Purchaser's rights under Article 13 hereof
pertaining to Seller's environmental indemnification) and proceed to close the
sale contemplated by this Agreement.

     24. GENERAL PROVISIONS.

     24.1 Governing Law; Interpretation; Section Headings. This Agreement shall
be governed by and construed and enforced in accordance with the laws of the
State of Texas, without regard to conflict-of-laws rules as applied in Michigan.
The section headings contained herein are for purposes


                                       45
<PAGE>   54


of convenience only, and shall not be deemed to constitute a part of this
Agreement or to affect the meaning or interpretation of this Agreement in any
way.

     24.2 Severability. Should any provision of this Agreement be held
unenforceable or invalid under the laws of the United States of America or the
State of Texas, or under any other applicable laws of any other jurisdiction,
then the parties hereto agree that such provision shall be deemed modified for
purposes of performance of this Agreement in such jurisdiction to the extent
necessary to render it lawful and enforceable, or if such a modification is not
possible without materially altering the intention of the parties hereto, then
such provision shall be severed herefrom for purposes of performance of this
Agreement in such jurisdiction. The validity of the remaining provisions of this
Agreement shall not be affected by any such modification or severance, except
that if any severance materially alters the intentions of the parties hereto as
expressed herein (a modification being permitted only if there is no material
alteration), then the parties hereto shall use commercially reasonable efforts
to agree to appropriate equitable amendments to this Agreement in light of such
severance, and if no such agreement can be reached within a reasonable time, any
party hereto may initiate arbitration under the then current commercial
arbitration rules of the American Arbitration Association to determine and
effect such appropriate equitable amendments.

     24.3 Entire Agreement. This Agreement, the Schedules and the documents and
agreements referenced herein set forth the entire agreement and understanding of
the parties hereto with respect to the transactions contemplated hereby, and
supersede all prior agreements, arrangements and understandings related to the

enforceable by the parties hereto and their respective heirs, executors,

parties hereto shall not be assigned or delegated by any party hereto without
the prior written consent of the other parties hereto.

     24.6 Amendment; Waiver. This Agreement may be amended, modified, superseded
or canceled, and any of the terms, provisions, representations, warranties,
covenants or conditions hereof may be waived, only by a written instrument
executed by all parties hereto, or, in the case of a waiver, by the party
waiving compliance. The failure of any party at any time or times to require
performance of any provision hereof shall in no manner affect the right to
enforce the same. No waiver by any party of any condition contained in this
Agreement, or of the breach of any term, provision, representation, warranty or
covenant contained in this Agreement, in any one or more instances, shall be
deemed to be or construed as a further or continuing waiver of any such
condition or breach, or as a waiver of any other condition or of the breach of
any other term, provision, representation, warranty or covenant.

performance of and compliance with this Agreement.

     24.12 Arbitration. Except for the provisions of Articles 14 and 15 of this
Agreement dealing with restrictive covenants and non-disclosure of confidential
information, with respect to which the Rush Parties expressly reserve the right
to petition a court directly for injunctive and other relief, any controversy of
any nature whatsoever, including but not limited to tort claims or contract
disputes, between the parties to this Agreement or their respective heirs,
executors, administrators, legal representatives, successors and assigns, as
applicable, arising out of or related to this Agreement, including the
implementation, applicability and interpretation thereof, shall, upon the
written request of one party served upon the other, be submitted to and settled
by arbitration in accordance with the provisions of the Federal Arbitration Act,
9 U.S.C. ss.ss.1-15, as amended. The terms of the commercial arbitration rules
of the American Arbitration Association shall apply except to the extent they
conflict with the provisions of this paragraph. If the amount in controversy in
the arbitration exceeds Two Hundred and Fifty Thousand Dollars ($250,000),
exclusive of interest, attorneys' fees and costs, the arbitration shall be
conducted by a panel of three independent arbitrators. Otherwise, the
arbitration shall be conducted by a single independent arbitrator. The parties
shall endeavor to select independent arbitrators by mutual agreement. If such
agreement cannot be reached within 30 calendar days after a dispute has arisen
which is to be decided by arbitration, the selection of the arbitrator(s) shall
be made in accordance with Rule 13 of the Rules as presently in effect. If three
arbitrators are selected, the arbitrators shall elect a chairperson to preside
at all meetings and hearings. If a dispute is to be resolved by a sole
arbitrator in accordance with the terms hereof, or if the dispute is to be
resolved by a panel of three arbitrators as provided hereinabove, then each such
arbitrator shall be a member of a state bar engaged in the practice of law in
the United States or a retired


                                       47
<PAGE>   56


member of a state or the federal judiciary in the United States. The award of
the arbitrator(s) shall require a majority of the arbitrators in the case of a
panel of arbitrators, shall be based on the evidence admitted and the
substantive law of the State of Texas and shall contain an award for each issue
and counterclaim. The award shall be made 30 days following the close of the
final hearing and the filing of any post hearing briefs authorized by the
arbitrator(s). The award of the arbitrator(s) shall be final and binding on the
parties hereto. Each party shall be entitled to inspect and obtain a copy of
non-privileged relevant documents in the possession or control of the other
party. All such discovery shall be in accordance with procedures approved by the
arbitrator(s). Unless otherwise provided in the award, each party shall bear its
own costs of discovery. Each party shall be entitled to take one deposition.
Each party shall be entitled to submit one set of interrogatories which require
no more than 30 answers. All discovery shall be expedited, consistent with the
nature and complexity of the claim or dispute and consistent with fairness and
justice. The arbitrator(s) shall have the power to compel any party to comply
with discovery requests of the other parties and to issue binding orders
relating to any discovery dispute which shall be enforceable in the same manner
as awards. The arbitrator(s) also shall have the power to impose sanctions for
abuse or frustration of the arbitration process, including without limitation,
the refusal to comply with orders of the arbitrator(s) relating to discovery and
compliance with subpoenas. Without limiting the scope of the parties' obligation
to arbitrate disputes pursuant to this Section, the arbitrator(s) are not
empowered to award damages including, without limitation, punitive damages and
multiple damages under applicable Texas statutes, in excess of compensatory
damages; provided that in no event shall consequential damages be awarded. Each
of Rush, Purchaser and Seller hereby irrevocably waives and releases any right
to recover such damages in excess of those damages authorized by this Section.
The arbitrator(s) may require the non-prevailing party to pay the prevailing
party's attorneys' fees and costs incurred in connection with the arbitration.
It is further agreed that any of the parties hereto may petition the United
States District Court for the Western District of Texas for a judgment to be
entered upon any award entered through such arbitration proceedings.

     24.13 Assignment of Contracts. Notwithstanding any other provision of this
Agreement, nothing in this Agreement or any related document shall be construed
as an attempt to assign (a) any Contract which, as a matter of law or by its
terms, is non-assignable without the consent of the other parties thereto unless
such consent has been given, or (b) any Contract or claim as to which all of the
remedies for the enforcement thereof enjoyed by Seller would not, as a matter of
law or by its terms, pass to Purchaser as an incident of the transfers and
assignments to be made under this Agreement. In order, however, that the full
value of every Contract and claim of the character described in clauses (a) and
(b) above and all claims and demands on such Contracts may be realized for the
benefit of Purchaser, Seller, at the request and expense and under the direction
of Purchaser, shall take all such action and do or cause to be done all such
things as will, in the opinion of Purchaser, be necessary or proper in order
that the obligations of Seller under such Contracts may be performed in such
manner that the value of such Contract will be preserved and will inure to the
benefit of Purchaser, and for, and to facilitate, the collection of the moneys
due and payable and to become due and payable thereunder to Purchaser in and
under every such contract and claim. Seller shall promptly pay over to Purchaser
all moneys collected by or paid to it in respect of every such contract, claim
or demand. Nothing in this Section shall relieve Seller of its obligations to
obtain any consents required for the transfer of the Assets and all rights
thereunder to Purchaser, or shall relieve Seller from any liability to Purchaser
for failure to obtain such consents.

<PAGE>   21


liabilities of Seller for the periods covered by such Governmental Returns.
Seller has no unpaid liability for any Taxes of any nature whatsoever for any
period prior to the date hereof. To the Best Knowledge of Seller and
Shareholder, none of the Governmental Returns of Seller or that include Seller
have been audited, and none are now under audit, by any Governmental Authority.

Part 4.7 of the Disclosure Schedule. Seller does not have any employee benefit
plans (including, but not limited to, pension plans and health or welfare

will have no liability with respect to any such plans as a result of the
transactions contemplated by this Agreement. Seller does not now contribute and
has not ever contributed to a "multiemployer plan" as defined in section
4001(a)(3) of the Employee Retirement Income Security Act of 1974, as amended
("ERISA"). Seller has complied with all applicable provisions of ERISA and all
rules and regulations promulgated thereunder and neither Seller nor any trustee,
administrator, fiduciary, agent or employee thereof has at anytime been involved
in a transaction that would constitute a "prohibited transaction" within the
meaning of Section 406 of ERISA. Seller is not a party to any collective
bargaining or other union agreements. Seller has not, within the last five
years, had or been threatened with any union activities, work stoppages or other
labor trouble with respect to its employees which had or might have had a
material adverse effect on any of the Business. To the Best Knowledge of Seller
and Shareholder, no union activities, work stoppages or other labor trouble with
respect to the employees of any of the customers or suppliers of the Business
are pending or threatened which might have an adverse effect on the Business.
Other than wage increases in the ordinary course of business, since the Balance
Sheet Date, Seller has not made any commitment or agreement to increase the
wages or modify the conditions or terms of employment of any of the employees of
Seller used in connection with the Business, and between the date of this
Agreement and the Closing Date, Seller will not make any agreement to increase
the wages or modify the conditions or terms of


                                       14
<PAGE>   22


employment of any of the employees of Seller used in connection with the
Business without the prior written approval of Purchaser.

     4.8 Contracts and Agreements. Part 4.8 of the Disclosure Schedule sets
forth a true and complete list of and briefly describes (including termination
date) all of the following contracts, agreements, leases, licenses, plans,
arrangements or commitments, written or oral, that relate to the Assets or the
Business (including all amendments, supplements and modifications thereto):

     products or services or the purchase of raw materials, supplies or other

     or other employee benefit plans, agreements, arrangements or commitments of
     any nature whatsoever, whether or not legally binding, and all agreements
     with any present or former officer, director or shareholder of Seller;

          (f) all loan or credit agreements, indentures, guarantees (other than
     endorsements made for collection), mortgages, pledges, conditional sales or
     other title retention agreements, and all equipment financing obligations,
     lease and lease-purchase agreements relating to or affecting the Assets or
     the Business;

          (g) all leases related to the Assets or the Business;

          (h) all performance bonds, bid bonds, surety bonds and the like, all
     contracts and bids covered by such bonds, and all letters of credit and
     guaranties;

          (i) all consent decrees and other judgments, decrees or orders,
     settlement agreements and agreements relating to competitive activities,

          (k) all contracts or agreements of any nature with Shareholder or any
     Affiliate of Shareholder; and

          (l) all contracts, commitments and agreements entered into outside the
     ordinary course of the operation of the Business.

All of such contracts, agreements, leases, licenses, plans, arrangements, and
commitments and all other such items included in the Assets but not specifically
described above (collectively, the "Contracts") are valid, binding and in full
force and effect in accordance with their terms and conditions and there is no
existing default thereunder or breach thereof by Seller, or, to the Best
Knowledge of Seller and Shareholder, by any other party to the Contracts, or any
conditions which, with the passage of time or the giving of notice or both,
might constitute such a default by Seller, or, to the Best Knowledge of Seller
and Shareholder, by any other party to the Contracts, and the Contracts will not
be breached by or give any other party a right of termination as a result of the
transactions contemplated by this Agreement. To the Best Knowledge of Seller and
Shareholder there is no reason why any of the Contracts (i) will result in a
loss to Purchaser on completion by performance or (ii) cannot readily be
fulfilled or performed by Purchaser with the Assets on time without undue or
unusual expenditure of money or effort. Copies of all of the documents (or in
the case of oral commitments, descriptions of the material terms thereof)
relevant to the Contracts listed in Part 4.8 of the Disclosure Schedule have
been delivered by Seller to Purchaser, and such copies and/or descriptions are
true, complete and accurate and include all amendments, supplements or
modifications thereto. After reviewing the Contracts, Purchaser may, at its sole
option, choose not to assume one or more of the Contracts, and, within 30 days
of receipt by Purchaser of all information reasonably requested by Purchaser
with respect to the Contracts, Purchaser shall notify Seller of which Contracts,
if any, Purchaser does not intend to assume hereunder. Except for Contracts, if
any, that Purchaser notifies Seller that it will not assume, all of the
Contracts are and shall be included in the Assets. All of the material Contracts
may be assigned to Purchaser without the approval or consent of any Person, or,
if such approval or consent is required, it will be obtained by Seller and
delivered to Purchaser at or prior to the Closing.

     4.9 Effect of Agreement. The execution and delivery of this Agreement and
the consummation of the transactions contemplated hereby will not (i) result in
any breach of any of the terms or conditions of, or constitute a default under,
the Articles of Incorporation or other charter documents or bylaws of Seller, or
any commitment, mortgage, note, bond, debenture, deed of trust, contract,
agreement, license or other instrument or obligation to which Seller is now a
party or by which Seller or any of its properties or assets may be bound or
affected; (ii) result in any violation of any Governmental Requirement
applicable to Seller, the Assets or the Business; (iii) cause Purchaser to lose
the benefit of any right or privilege included in the Assets; (iv) relieve any
Person of any obligation (whether contractual or otherwise) or enable any Person
to terminate any such obligation or any right or benefit enjoyed by Seller or to
exercise any right under any agreement in respect of the Assets or the Business;
or (v) require notice to or the consent, authorization, approval or order of any
Person


                                       16
<PAGE>   24


(except as may be contemplated by the last sentence of Section 4.8). To the Best
Knowledge of Seller and Shareholder, the business relationships of clients,
customers and suppliers of the Business will not be adversely affected by the
execution and delivery of this Agreement or the consummation of the transactions
contemplated hereby.

     4.18 Securities Laws Matters.

          (a) Except as expressly set forth in the Registration Rights
     Agreement, Seller recognizes and understands that the warrants described in
     Section 3.1 and the Common Stock issued upon exercise of such warrants
     (collectively, the "Securities") will not be registered under the
     Securities Act, or under the securities laws of any state (the Securities
     Act and such securities laws, collectively the "Securities Laws"). The
     Securities are not being so registered in reliance upon exemptions from the
     Securities Laws which are predicated, in part, on the representations,
     warranties and agreements of Seller contained herein.

          (b) (i) Seller has business knowledge and experience, such experience
     being based on actual participation therein, (ii) Seller is capable of
     evaluating the merits and risks of an investment in the Securities and the
     suitability thereof as an investment therefor, (iii) the Securities will be
     acquired solely for investment and not with a view toward resale or
     redistribution in violation of the Securities Laws, (iv) in connection with
     the transactions contemplated hereby, no assurances have been made
     concerning the future results of Purchaser or Rush or any Affiliate thereof
     or as to the value of the Securities and (v) Seller is an "accredited
     investor" within the meaning of (i) Regulation D promulgated by the SEC
     pursuant to the Securities Act and (ii) the Corporate Securities Laws of
     1968 of the State of California and the regulations promulgated thereunder.
     Seller understands that neither Purchaser nor Rush is under any obligation
     to file a registration statement or to take any other action under the
     Securities Laws with respect to any such Securities except as expressly set
     forth in the Registration Rights Agreement.

          (c) Seller has consulted with Seller's own counsel in regard to the
     Securities Laws and is fully aware (i) of the circumstances under which
     Seller is required to hold the Securities, (ii) of the limitations on the
     transfer or disposition of the Securities, (iii) that the Securities must
     be held indefinitely unless the transfer thereof is registered under the
     Securities Laws or an exemption from registration is available and (iv)
     that no exemption from registration is likely to become available for at
     least one year from the date of acquisition of the Securities. Seller has
     been advised by Seller's counsel as to the provisions of Rules 144 and 145
     as promulgated by the Commission under the Securities Act and has been
     advised of the applicable limitations thereof. Seller acknowledges that
     Purchaser and Rush are relying upon the truth and accuracy of the
     representations and warranties in this Section 4.18 by Seller in
     consummating the transactions contemplated by this Agreement without
     registering the Securities under the Securities Laws.

          SUCH LAWS WHICH, IN THE OPINION OF COUNSEL FOR THE HOLDER, WHICH
          COUNSEL AND OPINION ARE REASONABLY SATISFACTORY TO THE COUNSEL FOR
          THIS CORPORATION, IS AVAILABLE.

Seller understands and agrees that appropriate stop transfer notations will be
placed in the records of Rush and with its transfer agent in respect of the

or understandings made by or on behalf of Seller or Shareholder.

     4.20 Deposits. Seller does not hold any deposits or prepayments by third

insurance, fire department, sanitation department, health authority or other
governmental authority nor is there any matter under discussion with any such

     4.22 Telephone Numbers. All telephone numbers used by Seller in connection
with the Business are included in the Assets and will not be used by Seller or
Shareholder following the Closing, except by Shareholder in the conduct of
Purchaser's business.

     4.23 No Untrue Statements. The statements, representations and warranties
of Seller and Shareholder set forth in this Agreement, the Schedules, the Seller
Certificate and the exhibits and annexes attached hereto do not include (and in
the case of the Seller Certificate, will not include) any untrue statement of a
material fact or omit to state any material fact necessary to make the
statements, representations and warranties made not misleading. To the Best
Knowledge of Seller and Shareholder, there is no fact or matter that is not
disclosed to Purchaser in this Agreement or the Schedules that materially and
adversely affects or, so far as Seller or Shareholder can now reasonably
foresee, could materially and adversely affect the condition (financial or
otherwise) of any of the Assets or the Business or the ability of Seller or
Shareholder to perform their respective obligations under this Agreement.

     5. REPRESENTATIONS AND WARRANTIES OF PURCHASER. Purchaser represents and
warrants to Seller as follows:

     5.1 Incorporation. Purchaser and Rush are each a corporation duly
organized, validly existing and in good standing under the laws of the State of
Delaware and the State of Texas, respectively.

     5.2 Authorization. Purchaser has full legal right and corporate power to
enter into and deliver this Agreement and to consummate the transactions set
forth herein and to perform all the terms and conditions hereof to be performed
by it. This Agreement has been duly executed and delivered by Purchaser and is a
legal, valid and binding obligation of Purchaser enforceable in accordance with
its terms, except as limited by


                                       23
<PAGE>   31


applicable bankruptcy, moratorium, insolvency or other laws affecting generally
the rights of creditors or by principles of equity.

     5.3 SEC Documents. Rush has provided to Seller and Shareholder copies of
its Annual Report on Form 10-K for the year ended December 31, 1998, its
Quarterly Reports on Form 10-Q for the quarters ended March 31, 1999 and June
30, 1999, its proxy statement with respect to the Annual Meeting of Stockholders
held on May 18, 1999, and its Amendment No. 2 to Form S-1 Registration Statement
and Prospectus to Form S-1 filed on Form 424(b)(4) (such documents collectively
referred to herein as the "SEC Documents"). As of their respective dates, the
SEC Documents complied in all material respects with the requirements of the
Exchange Act and the rules and regulations of the Commission promulgated
thereunder applicable to such SEC Documents, and none of the SEC Documents
contained any untrue statement of a material fact or omitted to state a material
fact required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading. The consolidated financial statements of Rush included in the SEC
Documents comply as to form in all material respects with applicable accounting
requirements and the published rules and regulations of the Commission with
respect thereto, have been prepared in accordance with generally accepted
accounting principles applied on a consistent basis during the periods involved
(except as may be indicated in the notes thereto) and fairly present the
consolidated financial position of Rush and its consolidated Subsidiaries as of
the dates thereof and the consolidated results of their operations and cash
flows for the periods then ended (except in the case of interim period financial
information for normal year-end adjustments). All material agreements, contracts
and other documents required to be filed as exhibits to the SEC Documents have
been so filed. The consolidated balance sheet included in Rush's Quarterly
Report on Form 10-Q for the quarter ended June 30, 1999 reflects, as of the date
thereof, all liabilities, debts and obligations of any nature, kind or manner of
Rush and its subsidiaries, whether direct, accrued, absolute, contingent or
otherwise, and whether due or to become due that are required to be reflected on
such balance sheet under generally accepted accounting principles consistently
applied.

     5.4 Brokers and Finders. No broker or finder has acted for Purchaser or
Rush in connection with this Agreement or the transactions contemplated by this
Agreement and no broker or finder is entitled to any brokerage or finder's fee
or to any commission in respect thereof based in any way on agreements,
arrangements or understandings made by or on behalf of Purchaser or Rush.

     5.5 Effect of Agreement. The execution and delivery of this Agreement and
the consummation of the transactions contemplated hereby will not (i) result in
any breach of any of the terms or conditions of, or constitute a default under,
the Articles of Incorporation or other charter documents or bylaws of Purchaser,
or any


                                       24
<PAGE>   32


commitment, mortgage, note, bond, debenture, deed of trust, contract, agreement,
license or other instrument or obligation to which Purchaser is now a party or
by which Purchaser or any of its properties or assets may be bound or affected;
or (ii) result in any violation of any Governmental Requirement applicable to
Purchaser.

Article 10 (with such additions or exceptions to such items as are necessary to
make the statements set forth in such items accurate, provided that if any of
such additions or exceptions cause any of the conditions to Purchaser's
obligations hereunder as set forth in Article 10 not to be fulfilled, such
additions and exceptions shall in no way limit the rights of Purchaser under
Articles 10 and 18 to terminate this Agreement or refuse to consummate the

assets or to enter into any consent or similar order or agreement shall not
constitute a failure of Purchaser to use commercially reasonable efforts), and
(iv) deliver to Seller at the Closing the certificate contemplated by Article 11
(with such additions or exceptions to such certificate as are necessary to make
the statements set forth in such certificate accurate, provided that if any of
such additions or exceptions cause any of the conditions to Seller's obligations
hereunder as set forth in Article 11 not to be fulfilled, such additions and
exceptions shall in no way limit the rights of Seller under Articles 11 and 18
to terminate this Agreement or to refuse to consummate the transactions
contemplated hereby).

Purchaser shall each appoint one or more representatives knowledgeable in the

bear their cost of conducting such audit.

reasonably deems it inadvisable to proceed with the transactions contemplated by
this Agreement.

have occurred, and no loss or damage to any of the Assets, whether or not
covered by insurance, shall have occurred since the Balance Sheet Date, and

assumed by Purchaser, and Purchaser shall have no obligation or liability with
respect thereto.

          (a) By Seller and Shareholder. Seller and Shareholder recognize and
     acknowledge that they have and will have access to certain confidential
     information) of Seller that is included in the Assets (including, but not
     limited to, lists of customers, and costs and financial information) that
     after the consummation of the transactions contemplated hereby will be
     valuable, special and unique property of Purchaser. Seller and Shareholder
     agree that they will not disclose, and they will use their best efforts to
     prevent disclosure by any other Person of, any such confidential
     information to, nor any discussion of any of the terms of this Agreement
     with, any Person for any purpose or reason whatsoever, except to authorized
     representatives of Purchaser. Seller and Shareholder recognize and agree
     that violation of any of the agreements contained in this Section 12.6(a)
     will cause irreparable damage or injury to Purchaser, the exact amount of
     which may be impossible to ascertain, and that, for such reason, among
     others, Purchaser shall be entitled to an injunction, without the necessity
     of posting bond therefor, restraining any further violation of such
     agreements. Such rights to any injunction shall be in addition to, and not
     in limitation of, any other rights and remedies Purchaser may have at law
     or in equity against Seller or Shareholder.

          (b) By Purchaser. Purchaser recognizes and acknowledges that it may
     have access to certain confidential information of Seller that is not
     included in or connected with the Assets and not used or necessary for the
     Business that after the consummation of the transactions contemplated
     hereby will be valuable, special and unique property of Seller. Purchaser
     agrees that it will not disclose, and will use its best efforts to prevent
     disclosure by any other Person of, any such confidential information to any
     Person for any purpose or reason whatsoever, except to authorized
     representatives of Purchaser. Purchaser recognizes and agrees that
     violation of any of the agreements contained in this Section 12.6(b) will
     cause irreparable damage or injury to Seller, the exact amount of which may
     be impossible to ascertain, and that, for such reason, among others, Seller
     shall be entitled to an injunction, without the necessity of posting bond
     therefor, restraining any further violation of such agreements. Such rights
     to any injunction shall be in addition to, and not in limitation of, any
     other rights and remedies Seller may have at law or in equity against
     Purchaser.

          (c) Exceptions. The foregoing restrictions will not apply to any
     information which (a) becomes available to the public generally (otherwise
     than by reason of a breach of the


                                       34
<PAGE>   42


     provisions of this Section 12.6), (b) can be shown by written records to
     have been known by the disclosing party prior to the date of this Agreement
     or (c) is lawfully acquired by the disclosing party from another person. In
     the event any confidential information protected by this Section 12.6 is
     required to be disclosed under court or governmental order, rule or
     regulation, the party required to disclose such confidential information
     shall immediately provide the party entitled to protection hereunder with
     notice thereof and shall give full and complete cooperation to such party
     in its efforts to object to, and to obtain protection of any confidential
     information that is the subject of, such required disclosure.

     12.7 Assignment of Contracts. Notwithstanding any other provision of this
Agreement, nothing in this Agreement or any related document shall be construed
as an attempt to assign (i) any Contract which, as a matter of law or by its
terms, is non-assignable without the consent of the other parties thereto unless
such consent has been given, or (ii) any Contract or claim as to which all of
the remedies for the enforcement thereof enjoyed by Seller would not, as a
matter of law or by its terms, pass to Purchaser as an incident of the transfers
and assignments to be made under this Agreement. In order, however, that the
full value of every Contract and claim of the character described in clauses (i)
and (ii) above and all claims and demands on such Contracts may be realized for
the benefit of Purchaser, Seller, at the request and expense and under the
direction of Purchaser, shall take all such action and do or cause to be done
all such things as will, in the opinion of Purchaser, be necessary or proper in
order that the obligations of Seller under such Contracts may be performed in
such manner that the value of such Contract will be preserved and will inure to
the benefit of Purchaser, and for, and to facilitate, the collection of the
moneys due and payable and to become due and payable thereunder to Purchaser in
and under every such contract and claim. Seller shall promptly pay over to
Purchaser all moneys collected by or paid to it in respect of every such
contract, claim or demand. Nothing in this Section 12.7 shall relieve Seller or
Shareholder of their obligations to obtain any consents required for the
transfer of the Assets and all rights thereunder to Purchaser, or shall relieve
Seller or Shareholder from any liability to Purchaser for failure to obtain such
consents.

     12.8 Non-Compete, Non-Solicitation.

          (a) Non-Competition. In consideration of the benefits of this
     Agreement to Seller and Shareholder and as a material inducement to
     Purchaser to enter into this Agreement and to pay the Purchase Price,
     Seller and Shareholder, hereby covenant and agree that for a period of five
     years after the Closing Date, Seller and Shareholder shall not, and each
     shall cause their Affiliates not to, directly or indirectly, as proprietor,
     partner, stockholder, director, officer, employee, consultant, joint
     venturer, investor or in any other capacity, engage in, or own, manage,
     operate or control, or participate in the ownership, management, operation
     or control, of any entity which engages in the sale, servicing, renting,
     leasing, insuring or financing of new or used Class 3 through 8 trucks (not
     including construction equipment) in


                                       35
<PAGE>   43


     any geographical or commercial markets in which Rush or any of its
     Affiliates (including Purchaser) conducts such business on the Closing
     Date; provided, however, the foregoing shall not, in any event, prohibit
     Seller or Shareholder from (i) purchasing and holding as an investment not
     more than 1% of any class of publicly traded securities of any entity which
     conducts such business, so long as neither Seller nor Shareholder
     participates in any way in the management, operation or control of such
     entity or (ii) selling, leasing or otherwise disposing of any vehicles,
     parts and accessories inventory or chassis kits held by the Business as of
     the Closing Date that are not transferred to Purchaser pursuant to the
     terms of this Agreement. It is further recognized and agreed that, even
     though the activity may not be restricted under the foregoing provision,
     for a period of five years following the Closing Date, neither Seller nor
     Shareholder shall, and each shall cause their Affiliates not to, provide
     any services to any person or entity which may be used against, or in
     conflict with the interests of, Purchaser or an Affiliate of Purchaser.

          (b) Judicial Reformation. Seller and Shareholder acknowledge that,
     given the nature of Purchaser and its Affiliates' business, the covenants
     contained in this Section 12.8 establish reasonable limitations as to time,
     geographic area and scope of activity to be restrained and do not impose a
     greater restraint than is reasonably necessary to protect and preserve the
     goodwill of Purchaser and its Affiliates' business and to protect their
     legitimate business interests. If, however, this Section 12.8 is determined
     by any court of competent jurisdiction or an arbitrator pursuant to Section
     20.1 to be unenforceable by reason of it extending for too long a period of
     time or over too large a geographic area or by reason of it being too
     extensive in any other respect or for any other reason, it will be
     interpreted to extend only over the longest period of time for which it may
     be enforceable and/or over the largest geographic area as to which it may
     be enforceable and/or to the maximum extent in all other aspects as to
     which it may be enforceable, all as determined by such court or arbitrator.

          (c) Customer Lists, Non-Solicitation. In consideration of the benefits
     of this Agreement to Seller and Shareholder and as a material inducement to
     Purchaser to enter into this Agreement and to pay the Purchase Price,
     Seller and Shareholder hereby further covenant and agree that for a period
     of five years following the Closing Date, Seller and Shareholder shall not,
     and each shall cause their Affiliates not to, directly or indirectly, (a)
     use or make known to any person or entity the names or addresses of any
     clients or customers of Seller, Purchaser or any Affiliate of Purchaser or
     any other information pertaining to them, (b) call on, solicit, take away
     or attempt to call on, solicit or take away any clients or customers of
     Seller, Purchaser or any Affiliate of Purchaser, or (c) solicit for
     employment, recruit, hire or attempt to recruit or hire any employees of
     Seller, Purchaser or any Affiliate of Purchaser.

          (d) Equitable Relief. In the event of a breach or a threatened breach
     by Shareholder or Seller of any of the provisions contained in this Section
     12.8, each acknowledges that Purchaser and its Affiliates will suffer
     irreparable injury not fully compensable by money damages and, therefore,
     will not have an adequate remedy available at law. Accordingly, Purchaser
     shall be entitled, without the necessity of posting a bond, to obtain such
     injunctive


                                       36
<PAGE>   44


     relief or other equitable remedy from any court of competent jurisdiction
     as may be necessary or appropriate to prevent or curtail any such breach,
     threatened or actual. The foregoing shall be in addition to and without
     prejudice to any other rights that Purchaser may have under this Agreement,
     at law or in equity, including, without limitation, the right to sue for
     damages.

          (e) Covenants Independent. The covenants of Seller and Shareholder
     contained in this Section 12.8 will be construed as independent of any
     other provision in this Agreement, and the existence of any claim or cause
     of action by Seller or Shareholder, or any of them, against Purchaser or
     any Affiliate of Purchaser will not constitute a defense to the enforcement
     by Purchaser of said provisions. Seller and Shareholder understand that the
     provisions contained in this Section 12.8 are essential elements of the
     transactions contemplated by this Agreement and, but for their agreement to
     be bound by the provisions of this Section 12.8, Purchaser would not have
     agreed to enter into this Agreement and the transactions contemplated
     herein. Seller and Shareholder have each been advised to consult with, and
     each represents that it or he has consulted with, counsel in order to be
     informed in all respects concerning the reasonableness and propriety of the
     provisions of this Section 12.8 and each acknowledges that the provisions
     of this Section 12.8 are reasonable in all respects.

     12.9 Agreement Regarding GMC Excluded Assets. If as of the date that is six
months after the Closing Date, Purchaser has not entered into a dealer sales and
service agreement with GMC, the GMC Excluded Assets have not been sold pursuant
to the GMC Operating Agreement and Seller is not able to transfer the GMC
Excluded Assets to GMC or an Affiliate of GMC, Purchaser will purchase the GMC
Excluded Assets from Seller and Seller shall sell the GMC Excluded Assets to
Purchaser for the price indicated for such items in Section 3.1. The closing for
such sale and purchase shall take place at a date and time that is mutually
agreeable to the parties, which shall be no more than 30 days after Seller
provides Purchaser written notice that Seller is not able to transfer the GMC
Excluded Assets to GMC or an Affiliate of GMC. Seller, at its sole cost and
expense, shall provide all documentation and evidence reasonably requested by
Purchaser to enable Purchaser to verify that the conditions to Purchaser's
purchase obligations hereunder have been satisfied. At such closing, Purchaser
shall pay the amount due Seller by wire transfer of immediately available funds
to an account designated by Seller.

     12.10 Agreement Regarding Hino Excluded Assets. If as of the date of
termination of the Hino Operating Agreement, Purchaser has entered into a dealer
sales and service Agreement with Hino, Purchaser will purchase the Hino Excluded
Assets to the extent not previously sold under the Hino Operating Agreement from
Seller and Seller shall sell such Hino Excluded Assets to Purchaser for the
price indicated for such assets in Section 3.1. The closing for such sale and
purchase shall take place at a date and time that is mutually agreeable to the
parties, which shall be no more than 30 days after the termination date of the
Hino Operating Agreement. Seller, at its sole cost and expense, shall provide
all documentation and evidence reasonably requested


                                       37
<PAGE>   45


by Purchaser to enable Purchaser to verify the conditions to Purchaser's
purchase obligations hereunder have been satisfied. At such closing, Purchaser
shall pay the amount due Seller by wire transfer of immediately available funds
to an account designated by Seller.

Environmental Liabilities or obligations arising from acts, events or omissions
occurring prior to Seller's operation of the Business on any real property
owned, leased or used by Seller or any environmental condition or liability

costs and expenses incurred (whether any claims or causes of action relating

hereinafter defined) of any Seller Indemnifying Party occurring or existing
between the date Seller began conducting business on each parcel of real estate
owned, leased or used by Seller and the Closing Date, (b) any acts, omissions,
conditions, facts, or circumstances occurring or existing between the date
Seller began conducting business on each parcel of real estate owned, leased or

Seller Indemnifying Party to obtain or maintain, between the date Seller began
conducting business on each parcel of real estate owned, leased or used by
Seller and the Closing Date, any Environmental Permit. For purposes of this
Section 13.2 the term "Environmental Claim" means any action, lawsuit, claim or
proceeding by any Person relating to the Assets or the Business or the

<PAGE>   47

Requirements that relate to (i) noise, (ii) pollution or protection of the air,
surface water, groundwater or land, (iii) solid, gaseous or liquid waste
generation, handling, treatment, storage, disposal or transportation, (iv)

giving rise to a claim for indemnity under the provisions of this Agreement,
including receipt by it or any Purchaser Indemnified Party of notice of any
demand, assertion, claim, action or proceeding, judicial or otherwise, by any
Person with respect to any matter as to which any of the Purchaser Indemnified
Parties are entitled to indemnity under the provisions of this Agreement (such
actions being collectively referred to herein as a "Purchaser Claim"), Purchaser
will give prompt notice thereof in writing to the Seller Indemnifying Parties
together with a statement of such information respecting any of the foregoing as
it shall then have; provided that any delay in giving or failure to give such
notice shall not limit the rights of Purchaser or any Purchaser Indemnified
Party to indemnity hereunder except in accordance with the time limitations
provided in Section 13.10 and to the extent that the Seller Indemnifying Parties
are shown to have been damaged by such delay or failure.

     13.4 Right of the Seller Indemnifying Parties to Participate in Defense.

Parties seeks indemnity hereunder, Purchaser shall provide the Seller
Indemnifying Parties with the opportunity to participate in the defense of such
Purchaser Claim with counsel of the Seller Indemnifying Parties' choice and at
the Seller Indemnifying Parties' cost and expense and shall not, without the

unconditionally acknowledged their obligation to indemnify hereunder with
respect to such Purchaser Claim. To the extent reasonably requested by
Purchaser, shall reasonably cooperate with Purchaser and its representatives and
counsel in any dispute or defense related to any Purchaser Claim.

forth in Sections 4.6, 4.16 and 4.17 or any indemnification claim relating to
environmental matters.

     13.7 Limitations on Indemnification. Notwithstanding any provision of this
Agreement, the Seller Indemnifying Parties shall not be liable for any matter
that could be made the subject of a claim under this Article 13 regarding any
claims, losses, expenses or other liabilities until the aggregate amount thereof
exceeds $50,000 and after such threshold amount has been attained, all claims,
other than those aggregated to reach the threshold, shall be indemnified
hereunder.

     13.8 Insurance and Refunds. The Seller Indemnifying Parties'
indemnification obligations shall be reduced to the extent that the subject
matter of the claim is covered by and paid to Purchaser or its Affiliates
pursuant to a warranty or indemnification from a third party or third party
insurance. The amount of indemnification due from the Seller Indemnifying
Parties with respect to any claim shall be reduced by the effect of any tax
deduction, credit, refund or other tax benefit to Purchaser or it Affiliates
relating to the same tax period and resulting from the subject matter of that
claim and such indemnification.

     13.9 Offset Provisions. Notwithstanding any other provisions of this
Agreement, in the event, between the Closing Date and the date the Bonus Payment
is paid, the Seller Indemnifying Parties becomes obligated to pay sums to
Purchaser or any Purchaser Indemnified Party under this Agreement or any of the
documents or agreements referenced herein or contemplated hereby (whether as a
result of indemnity, breach of contract or otherwise), Purchaser shall have the
right to and shall be obligated to reduce and offset payments due on the Bonus
Payment in such amount or amounts as Purchaser (and any Purchaser Indemnified
Party that is not promptly paid by the Seller Indemnifying Parties) is entitled
to receive from the Seller Indemnifying Parties, and any such offset shall be
deemed to be a payment of the Bonus Payment to the extent of such offset;
provided, however, that any such offset shall not relieve the Seller
Indemnifying Parties from paying all amounts that are due in excess of the
amount offset. Prior to any offset under this Section 13.9, Purchaser shall have
provided to the Seller Indemnifying Parties a notice of Purchaser Claim as


                                       41
<PAGE>   49


described in Section 13.3 or an otherwise reasonably detailed description of the
matter giving rise to such offset.

     13.10 Time Limits for Indemnity Claims. Any claim for indemnification under

whatsoever, refund obligations (including, without limitation, interest and

resulting or arising from or incurred in connection with any one or more of the
following:

          (a) any liability or claim for liability (whether in contract, in tort
     or otherwise, and whether or not successful) related in any way to the
     Assets or the Business to the extent such liability or claim for liability
     arises in connection with any action, omission or event occurring after the
     Closing Date (including, but not limited to, claims for product liability
     with respect to products manufactured, distributed or sold by Purchaser
     after the Closing Date); and

          (b) any misrepresentation, breach of warranty or nonfulfillment of any

     any misrepresentation in or omission from any list, schedule, certificate
     or other instrument furnished or to be furnished to Seller or Shareholder
     pursuant to the terms of this Agreement.

causes of action relating thereto be asserted in common law or under statute and
regardless of form including strict liability and negligence) (collectively
referred to as "Seller Environmental Liabilities") arising from (a) any
violation of any Requirement of Environmental Law or Environmental Permits (as
those terms are


                                       42
<PAGE>   50


hereinafter defined) of Purchaser occurring after the Closing Date, (b) any
acts, omissions, conditions, facts, or circumstances occurring after the Closing

(c) any failure of Seller or Shareholder to obtain or maintain after the Closing
Date, any Environmental Permit. For purposes of this Section 14.2, the term

solid, gaseous or liquid waste generation, handling, treatment, storage,
disposal or transportation, (iv) exposure to hazardous or toxic substances, or
(v) any other matters related to health or the environment. Notwithstanding
anything herein to the contrary, Purchaser shall have no liability or obligation
to indemnify hereunder for any Seller Environmental Liabilities or obligations
arising from acts, events or omissions occurring after Purchaser ceases to
operate the Business on any of the premises to be owned, leased or used by
Purchaser pursuant to the provisions of Article 15.

     14.3 Notice of Claim. Seller and Shareholder agree that upon their
discovery of facts giving rise to a claim for indemnity under the provisions of
this Agreement, including receipt by Seller or Shareholder of notice of any
demand, assertion, claim, action or proceeding, judicial or otherwise, by any
Person with respect to any matter as to which Seller or Shareholder is entitled
to indemnity under the provisions of this Agreement (such actions being
collectively referred to herein as a "Seller Claim"), Seller and Shareholder
will give prompt notice thereof in writing to Purchaser together with a
statement of such information respecting any of the foregoing as they shall then
have; provided that any delay in giving or failure to give such notice shall


                                       43
<PAGE>   51


not limit the rights of Seller or Shareholder to indemnity hereunder except to
the extent that Purchaser is shown to have been damaged by such delay or
failure.

     14.4 Right of Purchaser to Participate in Defense. With respect to any
Seller Claim as to which Seller or Shareholder seeks indemnity hereunder, Seller
and Shareholder shall provide Purchaser with the opportunity to participate in
the defense of such Seller Claim with counsel of Purchaser's choice and at
Purchaser's cost and expense. To the extent reasonably requested by Seller and

Seller Claim.

     14.5 Payment. The Purchaser Indemnifying Parties shall promptly pay to
Seller and/or Shareholder, as applicable, in cash by wire transfer the amount of
any Seller Damages to which Seller and/or Shareholder, as applicable, may become
entitled by reason of the provisions of this Agreement.

     14.6 Limitations on Indemnification. Notwithstanding any provision of this
Agreement, Purchaser shall not be liable for any matter that could be made the
subject of a claim under this Article 14 regarding any claims, losses, expenses
or other liabilities until the aggregate amount thereof exceeds $50,000 and
after such threshold amount has been attained, all claims, other than those
aggregated to reach the threshold, shall be indemnified hereunder.

     14.7 Insurance and Refunds. Purchaser's indemnification obligations shall
be reduced to the extent that the subject matter of the claim is covered by and
paid to Seller or its Affiliates pursuant to a warranty or indemnification from
a third party or third party insurance. The amount of indemnification due from
Purchaser with respect to any claim shall be reduced by the effect of any tax
deduction, credit, refund or other tax benefit to either of Seller or its
Affiliates relating to the same tax period and resulting from the subject matter
of that claim and such indemnification.

     15. REAL PROPERTY.

          (a) San Diego, California Dealership. At Closing, Shareholder and
     Purchaser shall enter into a lease agreement in substantially the form of
     the Lease Agreement attached hereto as Exhibit 15(a) (the "San Diego
     Lease"), pursuant to which Shareholder will lease to Purchaser the property
     on which Seller's San Diego, California dealership is located.

          (b) Property Adjoining San Diego, California Dealership. At Closing,
     Seller shall assign to Purchaser its rights and Purchaser shall assume
     Seller's obligations under that certain Commercial Lease between Seller and
     Erickson Enterprises, formerly Red-e-Crete of San Diego ("Adjoining
     Property Landlord") dated May 26, 1994 (the "Adjoining Property Lease")
     relating to property adjoining the property on which Seller's San Diego

                                       44
<PAGE>   52


     is located. To evidence such assignment and assumption, Seller and
     Purchaser shall enter into an Assignment and Assumption of Tenant's
     Interest in Lease in substantially the form attached hereto as Exhibit

     consents necessary to assign its rights and obligations under the Adjoining
     Property Lease to Purchaser at Closing.

          (c) PACLEASE Facility. At Closing, Shareholder and Purchaser shall
     enter into a lease agreement in substantially the form of the Lease

     Lease"), pursuant to which the El Centro Landlord will lease to Purchaser
     the property on which Seller's El Centro, California dealership is located.

     16. SPECIAL PROVISIONS REGARDING EMPLOYEES OF SELLER.

     16.1 New Employees of Purchaser. It is the intention of Purchaser, and
Seller hereby acknowledges and agrees with such position, that any employees of
Seller that Purchaser hires will be new employees of Purchaser as of the Closing
Date or the date of hire, which ever is later. Such new employees shall be
entitled only to such compensation and employee benefits as are agreed to by
such employees and Purchaser, or as are otherwise provided by Purchaser, in its
sole discretion.

     16.2 No Hiring Commitment. Purchaser specifically does not commit to hire
any of the employees of the Business, and Seller specifically understands and
acknowledges this fact. However, notwithstanding Purchaser's position, Purchaser
will review its needs in anticipation of the purchase of the Assets with a view
to hiring certain of the employees of Seller as of the Closing Date. In its
review, Purchaser expects to be able to review employee records and conduct
employee interviews. Seller agrees that after the date hereof it will make, on a
confidential basis, its employee records available to Purchaser and permit
Purchaser to contact its employees for the purpose of conducting employee
interviews. Seller further agrees to make employees designated by Purchaser
available to Purchaser for such purpose.

     16.3 Existing Employee Benefit Plans; Assumption of Vacation and Sick Leave
Obligations. At the Closing, Purchaser shall assume Seller's obligations to
employees of Seller hired by Purchaser for accrued but unused vacation and sick
leave, and the Purchase Price shall be reduced by the dollar value of such
obligation. Except for vacation and sick leave time assumed by Purchaser as set
forth above, Purchaser shall have no obligation after the Closing to continue
any pension plans or work benefit


                                       45
<PAGE>   53


plans currently offered by Seller to its employees. Except for vacation and sick
leave time assumed by Purchaser as set forth above, Seller and Shareholder
jointly and severally agree to indemnify and hold harmless Purchaser from and
against any claim which may arise because of the failure to continue such
pension plans or work benefit programs.

     17. TERMINATION. This Agreement may be terminated without further
obligation of the parties, as follows:

     17.1 Mutual Consent. This Agreement may be terminated at any time prior to
Closing by mutual written consent of the parties hereto.

     17.2 Failure of Conditions. This Agreement may be terminated by either
party hereto, if the conditions, as set forth in this Agreement, to such party's
obligations under this Agreement are not fulfilled on or prior to the Closing
Date; provided that any such termination for any other reason shall not
otherwise limit the remedies otherwise available to such party as a result of
misrepresentations of or breaches by the other party.

     17.3 Failure to Close. This Agreement will automatically terminate on
February 1, 2000, if the Closing shall not have occurred on or before such date,
unless the parties shall have otherwise agreed in writing prior to such date. No
party will be liable in damages to any other party as a result of termination
pursuant to this Article 17 unless the failure of the Closing was due to the
failure of such party to comply with the terms of this Agreement.

Agreement in such jurisdiction. The validity of the remaining provisions of this
Agreement shall not be affected by any such modification or severance, except
that if any severance materially alters the intentions of the parties hereto as
expressed herein (a modification being permitted only if there is no material
alteration), then the parties hereto shall use commercially reasonable efforts
to agree to appropriate equitable amendments to this Agreement in light of such

     E. Binding Arbitration. Upon filing of a notice of demand for binding
arbitration by either party, arbitration shall be commenced and conducted as
follows:

          1. Arbitrators. All Disputes and related matters in question shall be
referred to and decided and settled by a panel of three arbitrators, one
selected by Purchaser, one selected by Shareholder and the third selected by the
two arbitrators so selected. Selection of the arbitrators to be selected by
Purchaser and Shareholder shall be made within ten (10) business days after the
date of giving of a notice of demand for arbitration, and the two arbitrators so
appointed shall appoint the third within 10 business days following their
appointment. No person who has a bias, or financial or personal interest in the
result of the arbitration or any past or present relationship with the parties
or their representatives shall serve as arbitrator

          2. Cost of Arbitration. The cost of arbitration proceedings, including
without limitation the arbitrators' compensation and expenses, hearing room
charges, court reporter transcript charges etc., shall be borne by the parties
equally or otherwise as the arbitrators may determine. The arbitrators may award
the prevailing party its reasonable attorneys' fees and costs incurred in
connection with the arbitration. The arbitrators are specifically instructed to
award attorneys' fees for instances of abuse in the discovery process.

          3. Location of Proceedings. The arbitration proceedings shall be held
in San Diego, California unless the parties agree otherwise.

          4. Pre-hearing Discovery. The parties shall have the right to conduct
and enforce pre- hearing discovery in accordance with the then current Federal
Rules of Civil Procedure, subject to these limitations:

               (a) Each party may serve no more than one set of interrogatories
     limited to 30 questions, including sub-parts;

               (b) Each party may depose the other party's expert witnesses who
     will be called to testify at the hearing, plus two fact witnesses without
     regard to whether they will be called to testify (each party will be
     entitled to a total of no more than 24 hours of deposition time of the
     other party's witnesses), provided however, that the arbitrators may
     provide for additional depositions upon showing of good cause; and

               (c) Document discovery and other discovery shall be under the
     control of and enforceable by the arbitrators.

          5. Discovery Disputes. All discovery disputes shall be decided by the
arbitrators. The arbitrators are empowered;

               (a) to issue subpoenas to compel pre-hearing document or
     deposition discovery;


                                 Appendix A-2-
<PAGE>   61


               (b) to enforce the discovery rights and obligations of the
     parties; and

               (c) to otherwise control the scheduling and conduct of the
     proceedings.

Notwithstanding any contrary foregoing provisions, the arbitrators shall have
the power and authority to, and to the fullest extent practicable shall,
abbreviate arbitration discovery in a manner which is fair to all parties in
order to expedite the conclusion of each alternative dispute resolution
proceeding.

          6. Pre-hearing Conference. Within fifteen (15) days after selection of
the third arbitrator, or as soon thereafter as is mutually convenient to the
arbitrators, the arbitrators shall hold a pre-hearing conference to establish
schedules for completion of discovery, for exchange of exhibit and witness
lists, for arbitration briefs and for the hearing, and to decide procedural
matters and address all other questions that may be presented.

          7. Hearing Procedures. The hearing shall be conducted to preserve its
privacy and to allow reasonable procedural due process. Rules of evidence need
not be strictly followed, and the hearing shall be streamlined as follows:

               (a) Documents shall be self-authenticating, subject to valid
     objection by the opposing party;

               (b) Expert reports, witness biographies, depositions and
     affidavits may be utilized, subject to the opponent's right of a live
     cross-examination of the witness in person;

               (c) Charts, graphs and summaries shall be utilized to present
     voluminous data, provided (i) that the underlying data is made available to
     the opposing party thirty (30) days prior to the hearing, and (ii) that the
     preparer of each chart, graph or summary is available for explanation and
     live cross-examination in person;

               (d) The hearing should be held on consecutive business days
     without interruption to the maximum extent practicable; and

               (e) The arbitrators shall establish all other procedural rules
     for the conduct of the arbitration in accordance with the rules of
     arbitration of the Center for Public Resources.

          8. Governing Law. This arbitration provision shall be governed by, and
all rights and obligations specifically enforceable under and pursuant to, the
Federal Arbitration Act (9 U.S.C. Section 1, et seq.)

          9. Consolidation. No arbitration shall include, by consolidation,
joinder or in any other manner, any additional person not a party to the
Agreement, except by written consent of both parties containing a specific
reference to these provisions.


                                 Appendix A-3-
<PAGE>   62


          10. Award. The arbitrators are empowered to render an award of general
compensatory damages and equitable relief (including, without limitations,
injunctive relief), but are not empowered to award exemplary, special or
punitive damages. The award rendered by the arbitrators (a) shall be final, (b)
shall not constitute a basis for collateral estoppel as to any issue and (c)
shall not be subject to vacation or modification.

          11. Confidentiality. The parties hereto will maintain the substance of
any proceedings hereunder in confidence and the arbitrators, prior to any
proceedings hereunder, will sign an agreement whereby the arbitrators agree to
keep the substance of any proceedings hereunder in confidence.

               [GENERAL MOTORS ACCEPTANCE CORPORATION LETTERHEAD]




                                February 1, 1999


Mr. W. Marvin Rush

Rush Truck Group (RUSH)



SUBJECT: SPECIAL WHOLESALE INCENTIVE PLAN INTEREST RATE ALLOWANCES


From time to time GMAC offers to dealers a reduced interest rate on new and used
floor plan finance obligations. This special rate is offered for competitive
reasons as an incentive to encourage dealers to provide GMAC with . It is known
as the Wholesale Incentive Plan ("WIP").

This letter confirms GMAC's agreement to provide RUSH with the following WIP:

         New and used wholesale floor plan and Borrowing Base Line of Credit,
         will be net billed at Prime minus .50 p.p. with maximum Credit Account
         Plan (CAP) at 50% of wholesale floor plan outstandings (the amount
         earned in the CAP shall be at a rate equivalent to the amount payable
         to GMAC on wholesale floor plan, less .25 p.p.). To qualify for this
         reduction, minimum wholesale outstandings must total at least $25
         million, GMAC must retain all current wholesale outstandings for
         franchises presently owned and in the future and GMAC must be provided
         first right of refusal on all future wholesale financing.

The WIP becomes effective as of February 1, 1999. It will remain in effect
indefinitely, subject to modifications, restrictions, qualifications, or
outright cancellation by GMAC at any time in its sole and absolute discretion;
provided that absent any default by you, any such change in the WIP will not be
effective except upon a thirty (30) day notice to you.

Notwithstanding the foregoing, your wholesale credit lines are expressly subject
to the written terms of the Wholesale Security Agreement under which they were
extended. They are discretionary lines of credit and may be modified, suspended
or terminated at our election, and at our sole and absolute discretion.

II.  SALE OF PRODUCTS

     A.   DEALER RESPONSIBILITIES.

          1.   PRODUCT Sales. DEALER's fundamental obligation under this
               AGREEMENT is to stock, sell at retail and service the PRODUCTS in

               sales and service performance in the local market in accordance
               with the criteria of Addendum C and this AGREEMENT. These

                    total registrations in this same period of all new trucks of
                    the same class (for this purpose, trucks of the same class
                    will be those selected by PETERBILT for comparison which
                    shall be generally competitive with PETERBILT Vehicles);

               d.   DEALER'S performance under subparagraph c above, as compared
                    with the performance of dealers similarly situated and with
                    the national average for all PETERBILT dealers, and with the
                    regional and district averages for all PETERBILT dealers in
                    the region and district to which DEALER is assigned.

               h.   DEALER'S inventory and sale of Genuine Parts and Accessories
                    in relation to the population of PETERBILT Vehicles and
                    similar vehicles of the same class in the area defined in
                    Addendum C; and

               i.   DEALER's participation in, and use of, other programs,
                    products and services offered by PETERBILT or PETERBILT
                    affiliates.

          3.   Sales Operations and Product Promotion. DEALER agrees to
               establish and maintain a sales organization in accordance with
               the requirements for a minimum number of personnel and training
               certification defined in Addendum C. DEALER agrees to conduct all
               sales activities in full compliance with PETERBILT's sales
               directives and to maintain a high standard of ethical sales
               activity and advertising. Under no circumstances will DEALER
               solicit or make sales through sub-dealers, agents, or
               representatives without the prior written consent of PETERBILT.
               DEALER acknowledges that PETERBILT may sell direct to major
               customers from time to time. If such sales occur, PETERBILT may
               compensate DEALER in a manner and an amount to be determined by
               PETERBILT for the contribution of the DEALER to the sale. DEALER
               further agrees to the following:

               a.   In order to maintain the confidence of the public in DEALER
                    and PRODUCTS, DEALER shall use its best efforts to sell each
                    customer PRODUCTS with specifications most appropriate to
                    the customer's application and will not mislead or deceive
                    its customers with respect to the specifications or
                    performance of PRODUCTS.

               b.   DEALER shall use its best efforts to promote the sale of
                    PRODUCTS in the area defined in Addendum C through
                    systematic contacts with owners and users and prospective
                    owners and users of PRODUCTS, and through such other means
                    as may be specified from time to time by PETERBILT in its
                    directives and suggestions.

<PAGE>   8


               c.   DEALER shall at all times carry in stock an adequate
                    inventory of unsold new PETERBILT Vehicles not ordered or
                    held for specific customers as may be sufficient to meet the
                    sales potential for PETERBILT Vehicles in the area defined
                    in Addendum C. DEALER shall also at all times carry in stock
                    an adequate inventory of Genuine Parts and Accessories as
                    may be required to meet the sales potential for Genuine
                    Parts and Accessories and the service needs of owners and
                    users of PETERBILT Vehicles in the area defined in Addendum
                    C.

               d.   In order to further sales of new PETERBILT Vehicles, DEALER
                    will engage in the purchase and sale of customer trade-ins
                    of used heavy-duty vehicles as may be required to
                    effectively compete in the area defined in Addendum C.
                    PETERBILT may from time to time provide DEALER with lists of
                    used heavy-duty vehicles available for sale. DEALER will use
                    its best efforts to market such used heavy-duty vehicles.

          4.   Sales Reporting. To assist PETERBILT in the evaluation of current
               market trends, DEALER upon request will deliver a report in a
               form prescribed by PETERBILT promptly upon delivery of new
               vehicles to a customer. DEALER will also furnish other market
               information reasonably requested by PETERBILT from time to time.

          5.   Purchase Orders. When placing orders for PRODUCTS, DEALER will
               only use purchase order forms provided by PETERBILT. All orders
               are subject to acceptance by PETERBILT. No order may be
               cancelled, except in accordance with PETERBILT's standard policy
               on order cancellation then in effect. PETERBILT will use its best
               efforts to fill any orders it has accepted, but will not be
               obligated to deliver to DEALER any particular number of PRODUCTS
               over a specific period of time.

          6.   Prices and Payments. PETERBILT may change prices and terms of
               sale from time to time. Unless otherwise agreed in writing,
               payments for Vehicles purchased shall be by medium of payment
               acceptable to PETERBILT against a wholesale line of credit
               established by DEALER and expressly approved by PETERBILT as
               provided for in Addendum D. PETERBILT will invoice DEALER for all
               PRODUCT purchases in accordance with PETERBILT's standard policy.
               In accordance with PETERBILT'S credit policy, PETERBILT may place
               sales of Genuine Parts and Accessories on a payment in advance
               basis. DEALER's right to return Genuine Parts and Accessories
               shall be governed by the terms of PETERBILT's parts return policy
               then in effect.

          7.   Payment Default. Should DEALER fail to pay for, or should any
               applicable financing arrangement fail to provide credit for the
               payment of, any PRODUCTS ordered by DEALER when payment is due,
               PETERBILT may take any of the actions set forth in Addendum D.

          8.   Delivery. PETERBILT will select the distribution points, carriers
               and modes of transportation for delivery of PRODUCTS to DEALER.
               DEALER will reimburse PETERBILT for delivery, freight, and
               related costs as set out on PETERBILT's invoice to DEALER. Unless
               otherwise provided under PETERBILT's warranty procedures, DEALER
               will file and pursue any claims against any carrier for loss or
               damage during shipment. PETERBILT will not be liable for delay or
               failure to fill orders that have been accepted where the failure
               or delay is the result of any cause beyond PETERBILT's reasonable
               control, including domestic or foreign laws, governmental
               actions, war or civil disturbance, acts of God, interruptions of
               navigation, shipwreck, strikes or other labor troubles, delays of
               suppliers or carriers.

          9.   Warranty. DEALER agrees that the only warranties that will be
               applicable to each new PRODUCT will be the written limited
               warranty furnished by PETERBILT to the first retail purchaser of
               the PRODUCTS as it may be revised from time to time. DEALER is
               not authorized to provide any additional warranties or assume any
               additional obligations or liabilities on behalf of PETERBILT.
               DEALER agrees that at the time the customer signs an order,
               DEALER will explain the warranty to the customer and obtain the
               customer's signature acknowledging receipt thereof.

          10.  PRODUCT Alterations. DEALER will not alter any PRODUCT, or change
               or substitute any of its components as sold by PETERBILT, if it
               might affect the safe mechanical operation, safety or structural
               integrity of any PRODUCT.

     B.   ADVERTISING.

          PETERBILT agrees to establish and maintain general advertising and
          promotion programs for the PRODUCTS. DEALER agrees to actively
          participate in cooperative advertising programs developed by PETERBILT
          from time to time for all DEALERS and to follow PETERBILT advertising
          guidelines in local advertising. DEALER also agrees to promote the
          purchase of PRODUCTS through DEALER's own advertising and sales
          promotion activities.

          Neither PETERBILT nor DEALER will publish any advertising likely to
          mislead or deceive the public or impair the good will of PETERBILT or
          DEALER or the reputation of the PRODUCTS.

III. SERVICE AND PARTS

     A.   DEALER RESPONSIBILITIES. DEALER agrees to establish and maintain a
          service and parts organization in accordance with the requirements for
          a minimum number of personnel with training certification defined in
          Addendum C. DEALER agrees to take all reasonable steps to provide
          service and parts for all PRODUCTS, regardless of where purchased, and
          whether or not under warranty, and to ensure that necessary repairs on
          PRODUCTS are performed in accordance with the highest professional
          standards and with the customer's consent.

          1.   Predelivery Service, Warranty Service, Campaign Inspections.
               DEALER will perform predelivery service on each new Vehicle,
               warranty service and recall campaign inspections and service in
               accordance with PETERBILT procedures then in effect. DEALER will
               procure special tools and service equipment as may be necessary
               to meet DEALER's obligations under this paragraph.

          2.   Reimbursement Rates. PETERBILT agrees to compensate DEALER for
               all warranty, and campaign inspection work related to recalls, in
               accordance with PETERBILT procedures and applicable law. Warranty
               service is provided for the benefit of customers and customers
               will not be obligated to pay any charges for warranty work,
               except as required by law.

          3.   Non-Genuine Parts or Accessories. DEALER has the right to sell,
               install or use parts or accessories which are not Genuine Parts
               and Accessories manufactured by or for PETERBILT. However, in
               cases where DEALER does not sell, install or use Genuine Parts
               and Accessories, DEALER will only use such other parts or
               accessories as will not adversely affect the mechanical operation
               or safety of the PRODUCTS being serviced or repaired, or will be
               equivalent in quality and design to Genuine Parts and
               Accessories.

               If DEALER uses parts or accessories which are not Genuine Parts
               and Accessories or are not approved by PETERBILT or the PACCAR
               Parts division for use in PRODUCTS, DEALER does so at its own
               risk and PETERBILT will not be responsible to DEALER or to any
               third party for any products liability, warranty or other claim
               which may arise as a consequence of the installation and/or use
               of such parts.

     B.   ASSISTANCE PROVIDED BY PETERBILT.

          1.   Customer Lists. PETERBILT may, from time to time, furnish DEALER
               with a list of potential customers of PRODUCTS located in the
               area defined in Addendum C. This will enable DEALER to maintain
               regular and periodic contact with each such customer and make
               every reasonable effort to sell PRODUCTS. Also, if available,
               PETERBILT will furnish DEALER with a list of the owners of
               Vehicles located in areas where such Vehicles could reasonably be
               brought to the DEALER for service. This will enable DEALER to
               maintain regular and periodic contact with each such Vehicle
               owner and make every reasonable effort to see that every owner is
               satisfied with their Vehicle(s).

          2.   Sales and Service Training Assistance. PETERBILT periodically
               will offer general and specialized truck and parts sales, and
               other service and technical training programs and materials.
               DEALER agrees that its sales, service and/or parts personnel will
               participate in these programs. Completion of training programs is
               required to comply with training standards or recommendations set
               out in Addendum C.

          3.   Service Manuals and Materials. PETERBILT agrees to make available
               to DEALER copies of service manuals and bulletins, publications
               and technical data as PETERBILT deems necessary for the effective
               operation of DEALER's service and parts organization. PETERBILT
               will use its best efforts to make available such data and
               information before new PRODUCTS are introduced for sale. DEALER
               agrees to keep these manuals, publications and data current and
               available for use by its parts and service employees.

          4.   Field Sales and Service Personnel Assistance. PETERBILT agrees to
               make available field personnel who will periodically advise
               DEALER on sales, parts and service related subjects, including
               fleet sales, product quality, technical adjustment, repair,
               replacement and sale of PRODUCTS, customer relations, warranty
               administration, and service and parts merchandising, training and
               management.

IV.  CAPITAL STANDARDS

     A.   NET WORKING CAPITAL. DEALER agrees to establish and maintain net
          working capital in accordance with Addendum D. If at anytime DEALER's
          net working capital falls below the minimum requirements as determined
          by PETERBILT financial standards for dealership capitalization, DEALER
          shall take all steps reasonably necessary to meet such minimum capital
          requirements.

     B.   OWNERSHIP. Addendum D also sets forth the identity of all DEALER
          owners and their respective ownership interests in DEALER (called
          "DEALER PRINCIPAL(S)") and the principal managers, who may or may not
          have ownership interests (called "OPERATING MANAGER(S)") of DEALER.
          DEALER acknowledges that this is a personal service contract. The
          effectiveness of DEALER is ultimately dependent upon the DEALER
          PRINCIPAL(S) and OPERATING MANAGER(S) who must assume full managerial
          authority and responsibility for DEALER business. No change in
          ownership or change in DEALER PRINCIPAL(S) shall be made without first
          consulting with and obtaining PETERBILT's prior written consent.
          DEALER also agrees to notify PETERBILT of any changes in OPERATING
          MANAGER(S). Any change approved by PETERBILT will be contained in a
          new Addendum D.

V.   ACCOUNTS, RECORDS AND REPORTS

     A.   UNIFORM ACCOUNTING SYSTEM. DEALER agrees to maintain a uniform
          accounting system designated by PETERBILT, and in accordance with
          PETERBILT policies, procedures and forms, as amended from time to
          time. In addition, DEALER will furnish to PETERBILT, by the twentieth
          of each month, in the manner set forth in the PETERBILT Accounting
          Manual and in a format and on forms prescribed by PETERBILT, a
          complete and accurate financial and operating statement covering the
          preceding month and DEALER's fiscal year-to-date operations. DEALER
          will also promptly furnish to PETERBILT a copy of any adjusted
          financial or operating statement prepared by or for DEALER.


                                  Page 5 of 13
<PAGE>   11


     B.   AUDIT OF DEALER RECORDS. DEALER agrees that PETERBILT will have the
          right, at all reasonable times and during DEALER's regular business
          hours, to examine, audit and reproduce all records, accounts and other
          data relating to the sale and service of PRODUCTS by DEALER. PETERBILT
          will provide a copy of the report of the examination or audit to
          DEALER upon request.

     C.   CONFIDENTIALITY. PETERBILT agrees that it will not provide any data or
          documents submitted to PETERBILT pursuant to this Article V to any
          independent third party, unless authorized by DEALER, required by law,
          or otherwise pertinent to legal proceedings. DEALER agrees that
          PETERBILT may provide such data to affiliated entities such as PACCAR
          Financial Corp., provided that such entities have agreed to comply
          with the terms of this provision governing confidentiality. DEALER
          also agrees that PETERBILT may use such data or documents to generate
          composite data which PETERBILT believes will be useful to share with
          its dealers to assist them in improving operations. Such composite
          data will not specifically identify any dealer.

VI.  TRADEMARKS, SERVICE MARKS AND TRADE NAMES

     A.   USE BY DEALER. PETERBILT authorizes DEALER to use the trade names,
          trademarks and logos of PETERBILT (hereinafter "Trademarks").
          PETERBILT grants to DEALER the nonexclusive privilege of displaying or
          otherwise using Trademarks solely in connection with the promotion and
          sale of PRODUCTS from approved location(s).

          DEALER agrees, however, that it will promptly discontinue the display
          and use of any Trademarks, and will change the manner in which any
          Trademarks are displayed and used when requested to do so by
          PETERBILT. DEALER further agrees that it will do nothing to impair the
          value of or contest PETERBILT's use or ownership of any trademark,
          design mark, service mark or trade name at any time acquired, claimed
          or adopted by PETERBILT. In addition, no company owned by or
          affiliated with DEALER or any DEALER PRINCIPALS may use any Trademarks
          or PRODUCT name without the prior written consent of PETERBILT.

     B.   DISCONTINUANCE OF USE. Upon termination, non-renewal or expiration of
          this AGREEMENT, DEALER agrees that it will immediately discontinue all
          use of the word "Peterbilt" and the Trademarks, or similar words and
          cease representing itself as an authorized PETERBILT Dealer.
          Thereafter DEALER will not use, either directly or indirectly, any
          Trademarks, trademarks of affiliated companies, or any other similar
          trademarks in a manner likely to cause confusion or mistake or to
          deceive the public. In addition, DEALER will promptly remove all
          PRODUCT signs bearing the word "Peterbilt" or the Trademarks from its
          facilities at DEALER's sole cost and expense. In the event DEALER
          fails to comply with its obligations herein within thirty (30) days of
          termination, non-renewal or expiration, PETERBILT will have the right
          to enter upon DEALER's premises and remove, without liability, all
          signs bearing the word "Peterbilt" or using any Trademarks. DEALER
          will reimburse PETERBILT for any costs and expenses incurred in
          connection with the enforcement of this paragraph, including
          reasonable attorney's fees.

VII. DEALER'S REPRESENTATION OF COMPETING LINES

     PETERBILT PRODUCTS have traditionally been sold primarily through
     independently owned dealerships. Representing multiple lines of competing
     truck manufacturers may create conflicts of interest resulting in
     inadequate representation of PETERBILT PRODUCTS. Demands on capital,
     personnel and other limited resources of a dealership may become
     increasingly difficult to balance when they must be allocated among several
     competing product lines. For these reasons, DEALER agrees not to enter into
     a written agreement to sell and service the competitive vehicles of another
     truck manufacturer without providing at least sixty (60) days prior written
     notice to PETERBILT so that PETERBILT may evaluate and discuss with DEALER
     the likely effect of such an action on DEALER, PETERBILT and other
     PETERBILT dealers. In conducting its evaluation PETERBILT will consider and
     discuss with DEALER the following:

     a.   Whether and to what degree the competing line competes with
          PETERBILT's major product lines;

     b.   Whether DEALER already represents the competing line with the
          acceptance or approval of PETERBILT;

     c.   Whether DEALER's representation of competing lines in another
          PETERBILT dealer's marketing area is likely to cause competitive
          injury to that dealer.

     d.   Whether DEALER's capital, personnel and management resources will be
          adequate to represent more than one line; and

     e.   For non-exclusive facilities, whether the facility is adequate to
          support an additional line.

VIII. TERMINATION OF AGREEMENT

     This section explains the circumstances under which the AGREEMENT may be
     terminated by either party, the procedure to be followed and the
     consequences of termination. Identifying specific events which could result
     in termination is intended to reduce the possibility of misunderstandings
     between PETERBILT and DEALER.

     A.   TERMINATION BY DEALER. DEALER may voluntarily terminate this AGREEMENT
          at any time by written notice to PETERBILT. Termination will be
          effective thirty (30) days after PETERBILT receives such notice unless
          otherwise mutually agreed in writing.

     B.   TERMINATION FOR CAUSE.

          1.   Immediate Termination. PETERBILT will have the right to terminate
               this AGREEMENT immediately in any of the following situations:

               a.   Any misrepresentation to PETERBILT by DEALER or any Owner or
                    DEALER PRINCIPAL in applying for this AGREEMENT or for
                    approval as Owner or DEALER PRINCIPAL of DEALER;

               b.   If DEALER, or any Owner, officer, or DEALER PRINCIPAL of
                    DEALER, is convicted of any felony or of any violation of
                    law which in PETERBILT's sole opinion tends to adversely
                    affect the business or interests of DEALER or PETERBILT, or
                    to impair good will associated with the Trademarks;

               c.   Submission by DEALER to PETERBILT of: (i) false claims for
                    reimbursement, sales incentives, warranty claims, refunds,
                    rebates or credits; (ii) false financial information, sales
                    reports or other data required by PETERBILT; or (iii) false
                    statements relating to predelivery or warranty service,
                    campaign inspections, servicing, repairing, or maintenance
                    required by PETERBILT;

               d.   If DEALER is closed for a period of five (5) consecutive
                    days, except when due to an event beyond DEALER's reasonable
                    control such as acts of God, war or civil disturbance, labor
                    strikes or other labor trouble;


                                  Page 7 of 13

               e.   Failure of DEALER to obtain or maintain any license, or the
                    suspension or revocation of any license, necessary for the
                    conduct by DEALER of its business pursuant to this
                    AGREEMENT; or

               f.   If DEALER becomes insolvent, as defined by the Uniform
                    Commercial Code, or files any voluntary petition under any
                    bankruptcy law, or executes an assignment for the benefit of
                    creditors, or any petition is filed by any third party to
                    have DEALER declared bankrupt or to appoint a receiver or
                    trustee, or another officer having similar power, and such
                    filing or appointment is not vacated within thirty (30) days
                    or there is any levy under attachment or execution or
                    similar process which is not vacated or removed by payment
                    or bonding within ten (10) days.

               g.   Any attempted or actual sale, transfer or assignment by
                    DEALER of this AGREEMENT, ownership interests in the DEALER,
                    or any of the rights granted DEALER under this AGREEMENT, or
                    any attempted or actual transfer, assignment or delegation
                    by DEALER of any of the responsibilities assumed by it under
                    the AGREEMENT, including but not limited to removal,
                    withdrawal or change of Owner or DEALER PRINCIPAL, without
                    the prior written consent of PETERBILT;

          2.   Termination Upon Sixty (60) Days Notice. If any of the following
               events has occurred and PETERBILT determines that the matter may
               require termination of this AGREEMENT, PETERBILT will so advise
               DEALER in writing. If DEALER does not correct the condition
               within thirty (30) days after notice is sent, PETERBILT will have
               the right to terminate this AGREEMENT upon an additional sixty
               (60) days notice, subject to DEALER's right to arbitrate under
               Article IX. Events which may result in such termination include:

               a.   he conduct, directly or indirectly, of DEALER's operations
                    from a facility other than a facility and location
                    specifically approved in Addendum B, without the prior
                    written consent of PETERBILT;

               b.   Any sale or transfer, by operation of law or otherwise, of
                    any of the location(s) approved in Addendum B or of
                    substantially all of the assets required in the conduct of
                    DEALER's operations, without the prior written consent of
                    PETERBILT;

               c.   Any dispute, disagreement or controversy between or among
                    Owners, DEALER PRINCIPALS, officers or managers of DEALER
                    which, in the sole opinion of PETERBILT, adversely affects
                    the operations, management, reputation or business interests
                    of DEALER or PETERBILT or the reputation of PETERBILT's
                    PRODUCTS;

               d.   Any refusal to permit PETERBILT to examine or audit DEALER's
                    accounts and records as provided in Article V upon receipt
                    by DEALER of written notice from PETERBILT requesting such
                    permission or information;

               e.   Repeated failure of DEALER to furnish timely sales or
                    financial information and related data;

               f.   Failure of DEALER to establish or maintain required net
                    working capital or adequate wholesale credit lines;

               g.   Failure of DEALER to pay PETERBILT for any PRODUCTS in
                    accordance with the terms and conditions of sale;

               h.   Failure of DEALER to accept an amended form of the AGREEMENT
                    or renewal within thirty (30) days after its presentation to
                    DEALER if the AGREEMENT is substantially the same as offered
                    and accepted by a substantial majority of PETERBILT dealers
                    or if any applicable law or regulation, or any new
                    interpretation thereof indicates that a change in any of the
                    provisions of the AGREEMENT is necessary or desirable;


                                  Page 8 of 13
<PAGE>   14


               i.   Entry by DEALER into a written agreement to sell and service
                    vehicles for another truck manufacturer at an exclusive
                    facility identified in Addendum B;

               j.   Other than performance failures set out below in Article
                    VIII.B.3, any other failure to comply with material
                    provisions of the AGREEMENT and/or minimum standards set
                    forth in Addenda to the AGREEMENT.

          3.   Termination For Failure of Performance on Ninety (90) Days
               Notice. If, upon evaluation of DEALER's performance pursuant to
               Addenda B and C, PETERBILT determines that DEALER has failed to
               perform adequately its sales responsibilities or to provide
               adequate facilities, PETERBILT will review promptly with DEALER
               the nature and extent of such failure(s). PETERBILT will notify
               DEALER in writing of DEALER's failure of performance and will
               grant DEALER one hundred eighty (180) days from the date of such
               notice to correct such failure(s). If DEALER fails or refuses to
               correct such failure(s) or has not made substantial progress
               towards remedying such failure(s) at the expiration of such
               period, PETERBILT may terminate this AGREEMENT upon ninety (90)
               days notice.

          4.   Termination Based on Market Withdrawal. This AGREEMENT will
               terminate upon the effective date of PETERBILT's ceasing to
               manufacture or sell PRODUCTS subject to any notice requirements
               under applicable federal or state laws.

          5.   Termination Upon Death or Incapacity. PETERBILT will have the
               right to terminate this AGREEMENT in the event of the death or
               incapacity of any Owner or DEALER PRINCIPAL identified in
               Addendum D, upon ninety (90) days written notice to DEALER.
               Notwithstanding its right to terminate under this paragraph 5,
               PETERBILT agrees to permit succession to majority ownership or
               DEALER PRINCIPAL by any person provided they are approved as an
               Owner or DEALER PRINCIPAL by PETERBILT in accordance with the
               then current policies and procedures of PETERBILT. Provided
               DEALER is not then in default under any of the provisions of this
               Article VIII, Company also will grant DEALER one hundred eighty
               (180) days from the date of such death or incapacity to submit a
               succession plan for PETERBILT's approval.

     C.   EFFECTIVE DATE OF TERMINATION. If any period of notice of termination
          required under this Article VIII is less than that required by
          applicable law, the period of notice required will be deemed to be the
          minimum period required by such law.

     D.   EFFECT OF TERMINATION.

          1.   The Right to Purchase PRODUCTS. Upon sending any notice of
               termination, expiration or non-renewal, PETERBILT will have no
               further obligation to sell and DEALER will have no right to
               purchase any PRODUCTS. Any decision to permit DEALER to purchase
               PRODUCTS thereafter will be in PETERBILT's sole discretion and
               will not be construed as a waiver of the termination or a
               renewal, extension or continuation of this AGREEMENT. Upon the
               expiration or prior termination of this AGREEMENT, PETERBILT will
               have the right to cancel any and all pending requests by DEALER
               to purchase PRODUCTS and any shipments scheduled for delivery to
               DEALER.

          2.   Repurchase of PRODUCTS.

               a.   PETERBILT's Obligations. Upon expiration, non-renewal or
                    termination of this AGREEMENT, PETERBILT will repurchase
                    from DEALER the following PRODUCTS which DEALER initially
                    purchased from PETERBILT or from a source designated by
                    PETERBILT:

                    (i)     New, unused, unmodified and undamaged current model
                            PETERBILT Vehicles then in DEALER's inventory. The
                            repurchase price will be the original purchase price
                            paid by DEALER, less all prior refunds or other
                            allowances made by PETERBILT to DEALER with respect
                            to the original purchase (and less standard freight
                            charges).

                    (ii)    New, unused and undamaged Genuine Parts and
                            Accessories then in DEALER's inventory which are in
                            good and saleable condition, provided that they are
                            listed in the then current PETERBILT Dealer Parts
                            Price List. The prices for such Genuine Parts and
                            Accessories will be the prices last established by
                            PETERBILT for dealers in the area in which DEALER is
                            located (less standard re-stocking and freight
                            charges).

                    (iii)   Tools and equipment required by PETERBILT and then
                            owned by DEALER especially designed for servicing
                            PETERBILT Vehicles. The purchase prices for tools
                            and equipment will be the price paid by DEALER less
                            appropriate depreciation or such other price as the
                            parties may negotiate.

                            PETERBILT shall have no obligation to repurchase
                            PRODUCTS as provided herein in the event DEALER and
                            PETERBILT agree to renew this AGREEMENT.

               b.   DEALER's Responsibilities. DEALER's right to reimbursement
                    under Article VIII.D.2.a is contingent upon the following:

                     (i).   Within thirty (30) days after the date of expiration
                            or the effective date of termination of this
                            AGREEMENT, DEALER will request PETERBILT in writing
                            to purchase the qualifying inventory and tools and
                            will provide PETERBILT with a detailed and accurate
                            list of such inventory and tools. After receiving
                            the list, PETERBILT may, in its discretion, enter
                            upon DEALER's premises to verify the inventory and
                            tools as qualifying under Article VIII.D.2.a.

                     (ii)   DEALER agrees to execute and deliver to PETERBILT
                            instruments satisfactory to PETERBILT conveying good
                            and marketable title to the inventory and tools as
                            PETERBILT may require. If such property is subject
                            to any lien or charge of any kind, DEALER agrees to
                            secure the discharge and satisfaction thereof prior
                            to the repurchase of the inventory and tools.

                     (iii)  DEALER agrees to allow PETERBILT to remove, at its
                            own expense, all signage bearing PETERBILT
                            Trademarks before DEALER is eligible for payment
                            hereunder.

               c.   Payment by PETERBILT. PETERBILT will make payment for all
                    repurchased items as soon as practicable upon DEALER's
                    compliance with the obligations set forth in Article
                    VIII.D.2.b, above. Any amount due DEALER at termination
                    shall be fully subject to set-off against any amounts owed
                    PETERBILT by DEALER.

IX.  VOLUNTARY ARBITRATION OF DISPUTES

     In order to encourage DEALER and PETERBILT to resolve disputes in an
     efficient and inexpensive manner, DEALER and PETERBILT may mutually agree
     that any disputes, protests, controversies or claims, whether for damages,
     stays of action or otherwise, ("Disputes"), may be resolved by arbitration.
     If DEALER and PETERBILT agree to arbitrate a Dispute, it shall be subject
     to arbitration under the following procedures:

     A.   FILING CLAIM. Unless otherwise agreed, arbitration may be initiated by
          DEALER filing a written request therefor no later than sixty (60) days
          after PETERBILT and DEALER have agreed to resolve the Dispute by
          arbitration. DEALER's written request to arbitrate, together with the
          appropriate filing fee, shall be filed by DEALER with the Office of
          the American Arbitration Association located nearest to the DEALER,
          which shall then become the site of the arbitration proceedings,
          unless otherwise agreed between the parties. The arbitration request
          should state clearly and completely the nature of DEALER's claim and
          its basis, the amount involved, if any, and the remedies sought.

     B.   EXCLUSIVE REMEDY. Unless the parties specifically agree otherwise at
          the time they elect to arbitrate the Dispute, arbitration shall be the
          sole and exclusive remedy of DEALER for that Dispute, and the decision
          and award of the arbitrator shall be final and binding on both
          parties. At DEALER's request, PETERBILT will agree to mediation of the
          Dispute prior to binding and final arbitration.

     C.   PROCEDURES. The arbitration and/or mediation will be conducted in
          accordance with the Commercial Rules of the American Arbitration
          Association then in effect (hereinafter referred to as the "Commercial
          Rules"), except as modified by mutual agreement of the parties, and in
          compliance with the United States Arbitration Act (9 U.S.C. Section 1,
          et. seq.).

     D.   CHOICE OF ARBITRATOR. Unless the DEALER at its option requests three
          (3) arbitrators, the arbitration shall be heard by a single arbitrator
          mutually agreeable to the parties, who, unless the parties agree
          otherwise, shall be an attorney at law admitted to practice for at
          least ten (10) years with substantial commercial experience and
          selected from a panel of American Arbitration Association arbitrators.
          If the parties fail to reach agreement within fifteen (15) days of the
          DEALER's request to arbitrate, an arbitrator (or three arbitrators, if
          the DEALER so elects) meeting these qualifications shall be named by
          the American Arbitration Association from such panel in accordance
          with the Commercial Rules, provided that the arbitrator(s) selected
          shall not have previously provided legal representation in litigation
          between motor vehicle manufacturers and motor vehicle dealers.

     E.   ARBITRATOR'S AWARD. If the arbitrator finds that PETERBILT has acted
          in accordance with provisions of this AGREEMENT, the standards set
          forth in 15 U.S.C. Sections 1221-1225 (the "Dealer's Day in Court
          Act"), and any applicable federal, state or local law, the arbitrator
          shall render an award in favor of PETERBILT. If the award in favor of
          PETERBILT relates to termination or nonrenewal of this AGREEMENT, the
          termination or nonrenewal shall be expressly recognized by DEALER as
          having been made without breach by PETERBILT of the AGREEMENT, the
          Dealer's Day in Court Act, or any applicable federal, state or local
          law. The termination or nonrenewal shall then become effective on the
          date of the award. If the arbitrator renders an award in favor of
          DEALER relating to a Dispute involving termination, PETERBILT's notice
          of termination shall be void and shall not be deemed to constitute a
          breach of this AGREEMENT. The arbitrator shall not have the authority
          to award punitive damages for any Dispute or to impose remedies
          unavailable in a court of law. The decision and award of the
          arbitrator shall be conclusive as to all matters within the
          arbitrator's jurisdiction in all other proceedings between parties,
          their successors or assigns, and judgment upon the award may be
          entered in any Court of competent jurisdiction.

     F.   PAYMENT OF FEES. The parties agree to compensate the arbitrator
          commensurate with the professional standing of the arbitrator and in
          accordance with the Commercial Rules. The compensation of the
          arbitrator, the administrative fees and charges of the American
          Arbitration Association, and the other expenses of the arbitration
          shall be borne equally by the parties and each party shall bear its
          own legal fees, provided that in all cases in which the DEALER is
          entitled to recovery of its legal fees under applicable state or
          federal law, PETERBILT shall pay such fees.

     G.   TIME PERIOD. Unless PETERBILT and DEALER specifically agree to the
          contrary, and subject to the Commercial Rules and the procedures of
          the American Arbitration Association, the arbitration hearing shall be
          concluded not more than one hundred and eighty (180) days after the
          date of DEALER's written request to arbitrate.

X.   DEFENSE AND INDEMNIFICATION BY PETERBILT

     PETERBILT will assume the defense of DEALER and agrees to indemnify and
     hold DEALER harmless in any legal proceeding naming DEALER as a defendant
     and involving any PRODUCT when the proceeding involves allegations of:
     breach of warranty, or a defect in manufacture or design; provided that
     PETERBILT has available sufficient evidence to support the conclusion that
     DEALER has not done or failed to do any act which would provide an
     independent basis for any allegations of liability against DEALER. DEALER
     agrees to cooperate fully in developing the facts necessary for defense of
     the lawsuits whether or not DEALER remains a party. The obligations of the
     parties set forth in this Article X shall survive the termination of this
     AGREEMENT.

XI.  MISCELLANEOUS PROVISIONS

     A.   ENTIRE AGREEMENT. This AGREEMENT and Addenda constitute the entire

          with such law. All provisions of this AGREEMENT shall be construed in
          light of this paragraph.

     F.   WAIVERS. Any failure of either party at any time to require
          performance by the other party of any provision herein will not be
          deemed to be a waiver by such party of any subsequent breach or
          violation of the same or any other provision.

          under or in connection with this AGREEMENT will be in writing and

          it with a new AGREEMENT in the new and superseding form for a term not
          less than the then unexpired term of this AGREEMENT. In that event,

          obligations or make representations binding upon PETERBILT.


By their signatures hereto, PETERBILT and DEALER agree to abide by the terms and
conditions of this AGREEMENT in good faith and for their mutual benefit.

                   DEALERSHIP LOCATION AND FACILITY STANDARDS

                            ----------------------.

PETERBILT has entered into this Agreement in reliance upon DEALER's
representation that it will establish and maintain DEALER facilities and
operations only at the following location(s) identified in this Addendum:


Main:  _______________                     Exclusive Heavy Duty     Yes
____________________                       Exclusive Medium Duty:   Yes
                                           Facility Type:           Full Service


Moreover, it is the mutual desire of DEALER and PETERBILT that DEALER's
facilities reflect a premium image and distinctive appearance consistent with
all other duly authorized PETERBILT dealers. DEALER agrees that the facilities
will at all times be in compliance with standards set forth in this Addendum, as
amended from time to time.

DEALER further agrees to the following:

1.   Operating Hours. DEALER will maintain its DEALER operations open for
     business during 5.5 days per week and 16 hours per day which are customary
     and lawful for truck dealers where DEALER is located.

2.   Signs. Subject to applicable law, DEALER will erect and maintain at the
     DEALER location(s), at DEALER's expense, standard product and service signs
     owned by PETERBILT, as well as such other signs authorized by PETERBILT as
     are necessary to identify the DEALER Operations effectively and as
     recommended by PETERBILT. DEALER shall in no way alter or modify the signs
     without obtaining prior written approval from PETERBILT.

3.   Computer Systems. DEALER will acquire, install, maintain and upgrade at
     DEALER's sole expense, standardized electronic data processing systems,
     business systems, communication systems and appropriate software compatible
     with PETERBILT's systems. The computer terminals for the system will be
     installed and maintained by DEALER at location(s) identified herein.
     Furthermore, DEALER will use the systems in accordance with PETERBILT's
     instructions.

4.   Evaluation of DEALER Facilities. PETERBILT will periodically evaluate
     DEALER's facilities in accordance with the terms of this Addendum.
     PETERBILT will provide DEALER with a written evaluation.

DEALER will maintain a facility which will reflect favorably upon and preserve
the goodwill of DEALER, PETERBILT and all other PETERBILT dealers and which will
meet PETERBILT's current minimum facilities standards as to size, cleanliness,
appearance, features, Peterbilt signage and corporate identity. DEALER shall use
the Peterbilt name in its legal name and/or a dba in a manner or form subject to
PETERBILT's prior approval. At such time as sales show the requirement for
additional facilities within the geographic area used by PETERBILT to establish
DEALER's sales quotas for Vehicles and Genuine Parts and Accessories, DEALER may
be expected to establish outlets in additional locations with the prior written
approval of PETERBILT.

It is agreed that each facility shall meet the following minimum standards:

     (1)  At least 20 service bays adequate for servicing heavy-duty trucks.

<PAGE>   21


For facilities designated as "exclusive" in this Addendum, DEALER agrees that
the facility will be dedicated to selling and servicing PETERBILT PRODUCTS and
DEALER acknowledges that PETERBILT has entered into this AGREEMENT in reliance
on DEALER's representation to provide and maintain an exclusive facility which
will not be used by DEALER to represent competitive truck manufacturers.

For nonexclusive facilities approved by PETERBILT, DEALER recognizes that if it
engages in other business activities in the facilities and/or on the DEALER
location(s), the facilities necessary for the sale and servicing of PRODUCTS may
be adversely affected. For these reasons, DEALER agrees that it will not
substantially modify, relocate, change the usage of, reduce or expand the DEALER
location(s) or the facilities without PETERBILT's prior approval.

All changes in the DEALER location(s) and facilities that may be agreed upon by
DEALER and PETERBILT pursuant to this Addendum shall be reflected in a new
Addendum B which supersedes and cancels the existing Addendum B.

thereof (and DEALER has not otherwise entered into an agreement with PETERBILT
governing succession); and

WHEREAS, PETERBILT desires to have an option to purchase and a right of first
refusal in the event DEALER decides to sell its business, or any branch thereof;

NOW, therefor, in consideration of the promises and mutual covenants of the
parties hereinafter set forth, it is agreed as follows:

1.   DEALER shall give PETERBILT notice in writing before undertaking any
     efforts to sell the dealership. The notice will contain a description of
     the assets to be sold, the proposed selling price, and other terms relevant
     to the sale. Upon request, PETERBILT agrees to provide assistance to DEALER
     in locating buyer candidates acceptable to both PETERBILT and DEALER,
     although DEALER shall independently negotiate any buy/sell agreement.
     PETERBILT also agrees to make best efforts to conditionally approve
     potential buyers to facilitate DEALER'S negotiations. Upon conditionally
     approving a specific buyer, PETERBILT will waive its right of first refusal
     as to that buyer.

2.   In the event PETERBILT refuses to approve DEALER's proposed transfer or
     sale of any ownership interest in the dealership, PETERBILT shall have
     under Paragraph 4 herein, the right of first refusal in the event the
     DEALER has entered into a written buy/sell agreement or, under Paragraph 5
     herein, an option to purchase the dealership assets, including any
     leasehold interest or realty, if the DEALER has not yet entered into such
     an agreement.

3.   If PETERBILT intends to exercise its right of first refusal and/or option
     to purchase the dealership, it must so advise DEALER in writing of its
     decision within thirty (30) days of receiving the DEALER'S written request
     for approval of sale or transfer to a bona fide buyer identified in
     DEALER's request. DEALER agrees that PETERBILT shall have the right to
     assign its right to exercise its option to purchase or right of first
     refusal to any third party it may select and PETERBILT hereby guarantees
     the full payment of the purchase price by such assignee.

4.   If PETERBILT has refused to approve the transfer or sale of DEALER'S
     ownership or assets and DEALER has entered into a bona fide arms length
     written agreement governing such transfer or sale, PETERBILT'S right under
     this paragraph shall be a right of first refusal, permitting PETERBILT to
     assume the buyer's rights and obligations under such written agreement. The
     purchase price and other terms of sale shall be those set forth in such
     agreement and any related documents. PETERBILT may request and DEALER
     agrees to provide any and all supporting documents relating to the transfer
     or sale which PETERBILT may require to assess the bona fides of the
     agreement. Refusal to provide such documentation or to state that no such
     documents exist shall create the presumption that the buy/sell agreement is
     not a bona fide agreement.


<PAGE>   26


5.   If PETERBILT has refused to approve the transfer or sale of DEALER'S
     ownership or assets and DEALER has not entered into a bona fide arms length
     written agreement governing such transfer or sale, then PETERBILT shall
     have the option to purchase the principal tangible and intangible assets of
     DEALER used in the dealership operations, including real estate and/or
     leasehold interest, and to terminate the Dealer Sales and Service
     Agreement. The purchase price for the dealership shall be the fair market
     value of the business as negotiated by the parties.





IN WITNESS WHEREOF, the parties have executed this Addendum as of the date set
forth below.

Mr. Marvin Rush, Chairman
Rush Enterprises
P O Box 346630
San Antonio, Texas 78265-4630

Dear Marvin:

PACCAR Financial Corp. is pleased to offer this Letter Agreement confirming the
2000/2001 "financing plan" for the Rush Enterprises' Peterbilt dealerships
listed below. In consideration of this preferred finance plan, our mutual
expectation is to reach at least 20% new Peterbilt finance penetration (units
financed/units sold) in the year 2000 (about $110 million in finance volume) and
at least 25% in 2001. The program described below is intended for "day to day"
business, and the parties are free to negotiate terms for other transactions as
needs arise.

PROGRAM PERIOD

January 1, 2000 through December 31, 2001, unless terminated by either party
prior to its conclusion.

RATES

New
5 year Treasuries plus 3.40 percent

Used

3 year Treasuries plus 4.25 percent

(1)  Three Year Treasury Rates for new and used, respectively, will be based on
     the weekly H-15 Treasury Interest Rate report. The rates appearing on the
     last Tuesday of the preceding month will be used for the following month.

(2)  The above rate structure will also be used for PFC's owner operator lease
     program (stream rate). 60-month leases with 10% residual will be at a .25%
     premium due to the longer amortization. The cost of PFC's liability
     insurance will be added to this rate structure, for owner operator leases.

DEALER LIABILITY

8%   New Non Fleet

5%*  New Transactions of 10 or more units

10%  Used


*    5% fixed, all other liability amounts based on the declining balance.
     Parties are free to negotiate LL of other amounts as conditions warrant.
     Nonrecourse is available for qualified credits.

ANNUAL LOSS CAP

The annual loss cap for the program period (2000 and 2001) will be $500,000 per
year, plus any additional recourse agreed to by the parties. This will be an
aggregate cap for all the Rush Peterbilt dealerships.

Rush Truck Centers of California, Inc.
Rush Truck Centers of Colorado, Inc.
Rush Truck Centers of Louisiana, Inc.
Rush Truck Centers of Oklahoma, Inc.
Rush Truck Centers of Arizona, Inc.
Rush Truck Centers of New Mexico, Inc.

DEALER RESERVE

Dealer reserve will be paid 100% upfront on new trucks up to a 3% dealer reserve
and up to a 5% dealer reserve on used trucks. Reserve amounts above 3% and 5%
will be split pro rata 75% for Rush and 25% for PFC. PFC's 25% will be added to
the program rate. The following illustrates this concept:

5.8%                               3.8%                          +.2%
Etc.                               Etc.                          Etc.
</TABLE>

Dealer fees on the owner operator lease program in excess of 10% of the
capitalized equipment cost will be split 50/50 with PFC.

The dealer's reserve payment and dealer fee on leases will be paid on the 15 th
of the following month. The difference in payment methods will be used on all
finance transactions. Dealer fees on leases will be expressed as a percentage of
the capitalized equipment cost.

CHARGEBACKS

Early terminations of any retail finance contract or modification of terms due
to a bankruptcy proceeding will result in a chargeback of unearned dealer
reserve to Rush Enterprises based on current PFC practices, where dealer reserve
is earned using the same method as interest earned on the underlying retail
contract.

On owner operator lease transactions, 100% of unearned dealer fees will be
charged back on a straight line basis throughout the term of the lease on all
early termination defaults, repossessions and bankruptcies where terms are
amended.


Transactions will be evaluated based on PFC's credit underwriting standards. PFC
will provide standard administrative services including contract administration
and collections.

This Letter Agreement shall be and hereby is incorporated into the Agreement for
Acquisition of Secured Retail Installment Paper between

Rush Truck Centers of Texas, Inc., Rush Truck Centers of California,
Inc., Rush Truck Centers of Colorado, Inc., Rush Truck Centers of
Louisiana, Inc., and Rush Truck Centers of Oklahoma, Inc., and PACCAR
Financial Corp., dated September 14, 1998, as well as any amendments
thereto (including work to incorporate the dealerships in New Mexico
and Arizona), and the Lease Marketing Agreement between the same
parties and of even date therewith, as well as any amendments and
attachments thereto (collectively, the "Rush Dealer Agreements").
Except for the modifications stated herein, the Rush Dealer Agreements
shall remain in full force and effect unchanged.

INSURANCE

PFC is pleased to offer the following commission structure for physical
damage insurance for the year 2000:

o    Standard Commission - 12.5% of Net Written Premium for all business (fleet
     and non-fleet) paid monthly.

o    Quarterly Bonus - 3.25% of Net Written Premium on volume over $300k (not
     retroactive) paid quarterly.

o    Annual Bonus - 1.25% of Net Written Premium on volume over $1.5 million
     (retroactive) paid annually.

o    Contingency Income - PFC's standard contingency program will remain in
     effect, allowing up to 8% of annual earned premium based on loss ratios.
     Contingency income is paid annually.

It is anticipated that the quarterly and annual targets will increase in 2001
and beyond and as our insurance relationship develops. Other Items:

1.   Other insurance in PFC contracts - With PFC's competitive commission
     structure outlined above, there should be little need to place other
     physical damage insurance in PFC contracts. However, PFC will consider
     exceptions when specific customer needs or market conditions warrant those
     exceptions.

2.   Specified perils versus comprehensive coverage - At this point in time, PFC
     does not offer comprehensive coverage. To manage your E&O exposure, we
     understand that you have the customer sign an acknowledgement in cases
     where specified perils is sold.

3.   Claims service - PFC's dedicated claims group, part of AIG, provides
     outstanding claims service. The utilization of independent appraisers
     allows for quick authorization of repairs and fast overall service. As we
     experience claims over the next year, we will review this service together.
     If the service is not satisfactory, we can develop a program similar to the
     Rapid Repair program used by Associates.
