                     RUSH ENTERPRISES, INC. AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (UNAUDITED)

1 - PRINCIPLES OF CONSOLIDATION AND BASIS OF PRESENTATION

         The interim consolidated financial statements included herein have been
prepared by Rush Enterprises, Inc. and its subsidiaries (collectively referred
to as the "Company"), without audit, pursuant to the rules and regulations of
the Securities and Exchange Commission ("SEC"). All adjustments have been made
to the accompanying interim consolidated financial statements which are, in the
opinion of the Company's management, necessary for a fair presentation of the
Company's operating results. All adjustments are of a normal recurring nature.
Certain information and footnote disclosures normally included in financial
statements prepared in accordance with generally accepted accounting principles
have been condensed or omitted pursuant to such rules and regulations. It is
recommended that these interim consolidated financial statements be read in
conjunction with the consolidated financial statements and the notes thereto
included in the Company's Annual Report on form 10-K for the year ended December
31, 1997.

2 - ACQUISITION

         In March 1998 the Company acquired all of the issued and outstanding
capital stock of D & D Farm and Ranch Supermarket Inc., for approximately $10.5
million. The acquisition was accounted for as a purchase. The results of
operations have been included in the Company's financial statements since the
date of acquisition. No pro forma financial information with regard to this
acquisition has been presented as the acquisition does not have a significant
impact on the Company's prior or current period financial position or results of
operations.

3 - COMMITMENTS AND CONTINGENCIES

         The Company is contingently liable to certain finance companies for
certain promissory notes and finance contracts, related to the sale of trucks
and construction equipment, sold to such finance companies. The Company's
recourse liability related to sold finance contracts is limited to 15 to 25
percent of the outstanding balance of each note sold to a finance company, with
the aggregate recourse liability for 1998 limited to $600,000.

         The Company provides an allowance for repossession losses and early
repayment penalties.

         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 to 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 certain individuals for an
aggregate monthly payment of $25,725. The agreements expire at various times
between 1999 through 2001.

5 - SEGMENT INFORMATION

         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 provides 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 Heavy
Duty Truck segment has locations in Texas, California, Colorado, Oklahoma and
Louisiana. The Construction Equipment segment, formed during 1997, operates a
full-service John Deere dealership that serves the Houston, Texas Metropolitan
and surrounding areas. Dealership operations include the retail sale of new and
used construction equipment, after-market parts and service facilities,
equipment rentals, and the financing of new and used equipment. The Company had
only one segment prior to the October 1997 acquisition of such John Deere
dealership, thus for the quarter ended March 31, 1997 results depict only the
Heavy Duty Truck segment.

The accounting policies of the segments are the same as those described in the
summary of significant accounting policies included in the Company's Annual
Report on Form 10-K for the year ended December 31, 1997. The Company evaluates
performance based on income before income taxes not including extraordinary
items.

The Company accounts for intersegment sales and transfers at current market
prices as if the sales or transfers were to third parties. There were no
intersegment sales during the three months ended March 31, 1998.

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 three months ended March 31, 1998: (in thousands)

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

                             RESULTS OF OPERATIONS


         Certain statements contained in this Form 10-Q are "forward-looking
statements" within the meaning of the Section 27A of the Securities Act of and
Section 21E of the Exchange Act. Specifically, all statements other than
statements of historical fact included in this Form 10-Q regarding the Company's
financial position, business strategy and plans and objectives of management of
the Company for future operations are forward-looking statements. These
forward-looking statements are based on the beliefs of the Company's management,
as well as assumptions made by and information currently available to the
Company's management. When used in this report, the words "anticipate,"
"believe," "estimate," "expect" and "intend" and words or phrases of similar
import, as they relate to the Company or its subsidiaries or Company management,
are intended to identify forward-looking statements. Such statements reflect the
current view of the Company with respect to future events and are subject to
certain risks, uncertainties and assumptions related to certain factors
including, without limitation, competitive factors, general economic conditions,
customer relations, relationships with vendors, the interest rate environment,
governmental regulation and supervision, seasonality, distribution networks,
product introductions and acceptance, technological change, changes in industry
practices, onetime events and other factors described herein and in the
Company's Registration Statement on Form S-1 (File No. 333-3346) and in the
Company's annual, quarterly and other reports filed with the Securities and
Exchange Commission (collectively, "cautionary statements"). Although the
Company believes that its expectations are reasonable, it can give no assurance
that such expectations will prove to be correct. Based upon changing conditions,
should any one or more of these risks or uncertainties materialize, or should
any underlying assumptions prove incorrect, actual results may vary materially
from those described herein as anticipated, believed, estimated, expected, or
intended. All subsequent written and oral forward-looking statements
attributable to the Company or persons acting on its behalf are expressly
qualified in their entirety by the applicable cautionary statements. The Company
does not intend to update these forward-looking statements.


         The following comments should be read in conjunction with the Company's
consolidated financial statements and related notes included elsewhere in this
Quarterly Report on Form 10-Q.

GENERAL

         Rush Enterprises, Inc. was incorporated in Texas in 1965 and currently
consists of 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 Company's truck centers
are strategically located in high truck traffic areas on or near major highways
in Texas, California, Oklahoma, Colorado and Louisiana. The Company is the
largest Peterbilt truck dealer in the United States, representing approximately
14.7% of all new Peterbilt truck sales in 1997, and is the sole authorized
vendor for new Peterbilt trucks and replacement parts in its market areas. The
Company was named Peterbilt Dealer of the Year for North America for the
1993-1994 year. The criteria used to determine the recipients of this award
include, among others, image, customer satisfaction, sales activity and
profitability.


    The Construction Equipment segment, formed during 1997, operates a
full-service John Deere dealership (the "Rush Equipment Center") that serves the
Houston, Texas Metropolitan and surrounding areas. Dealership operations include
the retail sale of new and used construction equipment, after-market parts and
service facilities, equipment rentals, and the financing of new and used
construction equipment. The Company believes the construction equipment industry
is highly-fragmented and offers opportunities 


                                       9
<PAGE>   10
for consolidation. As a result, the Company's growth strategy is to realize
economies of scale, favorable purchasing power, and cost savings by developing a
network of John Deere dealerships through acquisitions and growth inside
existing territories. The Company currently operates only one construction
equipment dealership and there can be no assurance that the Company will be able
to successfully develop a network of construction equipment dealerships or, if
such network of construction equipment dealerships is established, that it will
realize economies of scale, favorable purchasing power or cost savings.

         In March 1997, the Company acquired 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
cash and borrowings under the Company's floor plan financing arrangement.

         In September 1997, the Company opened a Rush Truck Center in Pharr,
Texas. This full-service Peterbilt dealership serves the Texas Rio Grande Valley
area.

         In October 1997, the Company acquired certain assets and assumed
certain liabilities from C. Jim Stewart & Stevenson, Inc., which consisted of
its full service John Deere construction equipment dealership serving the
Houston, Texas metropolitan and surrounding areas. The purchase price was
approximately $30.2 million funded by cash, borrowings from various creditors,
and a note payable issued to the seller.

         In March 1998, the Company acquired all of the outstanding capital
stock of D & D Farm and Ranch Supermarket, Inc. ("D & D"), for consideration of
approximately $10.5 million. D & D operates a retail farm and ranch superstore
in the Greater San Antonio, Texas area.

THREE MONTHS ENDED MARCH 31, 1998 COMPARED TO THREE MONTHS ENDED MARCH 31, 1997

Revenues

         Revenues increased by approximately $43.2 million, or 52.1%, from $82.9
million to $126.1 million from the first quarter of 1997 to the first quarter of
1998. Approximately, $23.6 million in sales is attributable to the addition of
the Colorado and Pharr heavy-duty truck dealerships, and the John Deere
construction equipment dealership, while the remaining increase of $19.6 million
or 23.6%, is attributable to same store growth. Sales of new and used trucks
increased by approximately $23.2 million, or 37.5%, from $61.8 million to $85.0
million from the first quarter of 1997 to the first quarter of 1998. Unit sales
of new and used trucks increased by 25.3% and 34.3%, respectively, from the
first quarter of 1997 to the first quarter of 1998, while new truck average
revenue per unit increased by 5.8% and used truck average revenue per unit
increased by 16.8%. Average new truck prices and used truck prices increased due
to a change in product mix, and used truck demands increased due to increasing
delivery times on new truck orders.

         Parts and service sales increased by approximately $7.0 million, or
43.0%, from $16.3 million to $23.3 million. The increase was due to same store
growth of 21.6% and parts and service sales associated with addition of the
Colorado and Pharr heavy-duty truck dealerships, and the John Deere construction
equipment dealership.

         Lease and rental revenues increased by approximately $1.6 million, or
50.0% from $3.2 million to $4.8 million. The increase was due to $1.2 million of
lease and rental revenues generated by the John Deere dealership acquired in
October 1997, and same store growth in revenues of $396,000 or 12.4%.

         Finance and insurance revenues increased by approximately $1.3 million,
or 130.0%, from $1.0 million to $2.3 million from the first quarter of 1997 to
the first quarter of 1998. The majority of the increase resulted from the
increase in used truck deliveries. Finance and insurance revenues have limited
direct costs and, therefore, contribute a disproportionate share of operating
profits.

Gross Profit

         Gross profit increased by approximately $8.5 million, or 64.4%, from
$13.2 million to $21.7 million from the first quarter of 1997 to the first
quarter of 1998. Gross profit as a percentage of sales increased from 15.9% in
the first quarter of 1997 to 17.2% in the first quarter of 1998. The increase in
gross profit resulted from an increase in the sales mix to the parts, service
and body shop departments, in addition to increased gross margins on used truck,
service and body shop sales, as well as the addition of the Rush Equipment
Center, which achieved a gross margin of 19.6%. These margin increases were
offset by slight decreases in gross margins on new truck and parts sales.


Selling, General and Administrative Expenses

         Selling, general and administrative expenses increased by approximately
$6.4 million, from $10.8 million to $17.2 million, or 59.3%, from the first
quarter of 1997 to the first quarter of 1998. The increase resulted from
approximately $3.5 million of selling, general and administrative expense
related to the acquisition and integration of Denver Peterbilt Inc., the John
Deere construction equipment dealership, and D & D Farm and Ranch Supermarket,
Inc., and increased sales commissions resulting from increased gross margins.

Interest Expense

         Interest expense increased by approximately $808,000 or 164.9%, from
$490,000 to $1.3 million, from the first quarter of 1997 to the first quarter of
1998, primarily as the 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.


                                       11

Income before Income Taxes

         Income before income taxes increased by $961,000, or 73.9%, from $1.3
million to $2.3 million from the first quarter of 1997 to the first quarter of
1998, as a result of the factors described above.

Income Taxes

The Company has provided for taxes at a 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 the
acquisition of new facilities. These short-term cash needs have historically
been financed with retained earnings and borrowings under credit facilities
available to the Company.

         In June 1996, the Company completed an initial public offering of
2,875,000 shares of common stock and received net proceeds of approximately
$32.1 million.

         As a result of the initial public offering, working capital levels have
generally increased. At March 31, 1998, the Company had working capital of
approximately $21.7 million, including $17.9 million in cash and cash
equivalents, $25.9 million in accounts receivable, $88.2 million in inventories,
and $0.5 million in prepaid expenses, less $18.5 million of accounts payable and
accrued expenses, $2.8 million of current maturities on long-term debt, $5.6
million in a note payable to a shareholder, and $83.9 million outstanding under
floor plan financing. The aggregate maximum borrowing limits under working
capital lines of credit with various commercial banks are approximately $8.0
million. The Company's floor plan agreements with its primary lender limit the
aggregate amount of borrowings based on the number of new and used trucks and
the book value of construction equipment inventory.

         For the first three months of 1998, operating activities resulted in
net cash used in operations of approximately $19.7 million. Net income of $1.3
million, an increase in accrued liabilities coupled with provisions for
depreciation, amortization and deferred taxes totaling $1.4 million was more
than offset by increases in accounts receivable, inventories and other assets
and a decrease in accounts payable totaling $22.4 million.

         For the first three months of 1997, operating activities generated
$16.8 million of cash. Net income of $785,000, a decrease in accounts
receivable, inventories and other assets, coupled with provisions for
depreciation, amortization, and deferred taxes totaling $18.7 million more than
offset decreases in accounts payable and accrued liabilities of $2.7 million.

         During the first three months of 1998, the Company used $9.7 million in
investing activities, including purchases of property, plant and equipment of
$4.6 million, a cash outlay of $5.8 million for the acquisition of D & D Farm
and Ranch Supermarket, Inc., offset by proceeds from the sale of property, plant
and equipment and a decrease in other assets totaling $746,000.

         During the first three months of 1997, the Company used $8.9 million
for investing activities, primarily related to the acquisition of Denver
Peterbilt, Inc..

         Net cash generated from financing activities in the first three months
of 1998 amounted to $27.4 million. Proceeds from additional floor plan financing
and increased notes payable more than offset principal payments on notes
payable.

         For the first three months of 1997, net cash used in financing
activities amounted to $13.7 million. Payments on floor plan financing and
principal payments on notes payable more than offset the increase in notes
payable.



                                       12
<PAGE>   13

         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 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
to GMAC prior to the sale of new vehicles for a period of 12 months and for used
vehicles for a period of three months. At March 31, 1998, the Company had
approximately $54.8 million outstanding under its floor plan financing
arrangement with GMAC. GMAC permits the Company to earn, for up to 62.5% of the
amount borrowed under its floor plan financing arrangement with GMAC, interest
at the prime rate less one-half percent on overnight funds deposited by the
Company with GMAC.

         The Company finances all, or substantially all, of the purchase price
of its new equipment inventory under its floor plan facilities with John Deere
and Associates Commercial Corp.. The agreement with John Deere provides for an
immediate 3% discount if the equipment is paid for within 30 days from the date
of purchase, or interest free financing for five months, after which time the
amount financed is required to be paid in full. When the equipment is sold prior
to the expiration of the five month period, the Company is required to repay the
principal within approximately 15 days of date of the sale. Should the equipment
financed by John Deere not be sold within the five month period, it is
transferred to the Associates Commercial Corp. floor plan arrangement. The
Company makes principal payments to Associates Commercial Corp., for sold
inventory, and interest payments for all 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 Corp. 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 inventory, on 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 March
31, 1998, the Company's floor plan arrangement with Associates Commercial Corp.
permits the financing of up to $25 million in construction equipment. At March
31, 1998, the Company had $8.7 million and $20.4 million, outstanding under its
floor plan financing arrangements with John Deere and Associates Commercial
Corp., respectively.

Backlogs

         The Company enters firm orders into its backlog at the time the order
is received. Currently, customer orders are being filled in approximately six to
nine months and customers have historically placed orders expecting delivery
within three to six months. However, certain customers, including fleets and
governments, typically place orders up to one year in advance of their desired
delivery date. The Company in the past has typically allowed customers to cancel
orders at any time prior to delivery, and the Company's level of cancellations
is affected by general economic conditions, economic recessions and customer
business cycles. As a percentage of orders, cancellations historically have
ranged from 5% to 12% of annual order volume. The Company's backlogs as of March
31, 1998, and 1997, were approximately $150 million and $95.0 million,
respectively. Backlogs increased principally due to the above noted longer lead
times for truck deliveries at March 31, 1998, compared to March 31, 1997,
delivery lead times of 75 to 90 days.

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.


                                       13
<PAGE>   14


         Seasonal effects in the construction equipment business are primarily
driven by weather conditions. As the Rush Equipment Center is located in
Houston, Texas, where winters are mild, seasonality currently does not have a
material effect on the Company's construction equipment segment. Additionally,
any 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.


Cyclicality

         The Company's business, as well as the entire retail heavy-duty truck
and construction equipment industries, are 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 and construction equipment have historically been
subject to substantial cyclical variation based on such general economic
conditions. Although the Company believes that its geographic expansion and
diversification into truck and construction equipment 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.

Effects of Inflation

         The Company believes that the relatively moderate inflation over the
last few years has not had a significant impact on the Company's revenue or
profitability. The company does not expect inflation to have any near-term
material effect on the sales of its products, although there can be no assurance
that such an effect will not occur in the future.

Year 2000

         The efficient operation of the Company's business is dependent on its
computer software programs and operating systems (collectively, "Programs and
Systems"). These Programs and Systems are used in several key areas of the
Company's business, including information management services and financial
reporting, as well as in various administrative functions. The Company has been
evaluating its Programs and Systems to identify potential year 2000 compliance
problems, as well as manual processes, external interfaces with customers, and
services supplied by vendors to coordinate year 2000 compliance and conversion.
The year 2000 problem refers to the limitations of the programming code in
certain existing software programs to recognize date sensitive information for
the year 2000 and beyond. Unless modified prior to the year 2000, such systems
may not properly recognize such information and could generate erroneous data or
cause a system to fail to operate properly.

         Based on current information, the Company expects to attain year 2000
compliance and institute appropriate testing of its modifications and
replacements in a timely fashion and in advance of the year 2000 date change. It
is anticipated that modification or replacement of the Company's Programs and
Systems will be performed in-house by Company personnel. The Company believes
that, with modifications to existing software and conversions to new software,
the year 2000 problem will not pose a significant operational problem for the
Company. However, because most computer systems are, by their very nature,
interdependent, it is possible that non-compliant third party computers may not
interface properly with the Company's computer systems. The Company could be
adversely affected by the year 2000 problem if it or unrelated parties fail to
successfully address this issue. Management of the Company currently anticipates
that the expenses and capital expenditures associated with its year 2000
compliance project will not have a material effect on its financial position or
results of operations.

                                   ARTICLE II

                         BORROWING BASE LINE OF CREDIT

         Section 2.01  Consolidation of Borrowing Base Loans.  The credit
facility and funding terms of the Borrowing Base Loans shall be modified and
governed in accordance with this Article II.

         Section 2.02  Establishment of Line of Credit.  Subject to the terms
and conditions of this Agreement, GMAC hereby establishes a revolving line of
credit for Borrower in an amount not to exceed the lesser of:

         (a)  $8,000,000, or

         (b)  the Collateral Formula Amount, as defined in Section 2.07 below.

The amount available for loan under this Article II is referred to as the Line
of Credit.  If, for any reason, the Credit Line Advances (defined below) shall
exceed the Line of Credit as determined above (such excess being hereinafter
referred to as Excess Amounts), the Line of Credit shall be deemed to include
the Excess Amounts for all purposes hereunder, except that Excess Amounts are
temporary only and shall not be deemed to permanently increase the Line of
Credit.

         Section 2.03  Loans.  Within 3 Business Days after each request made
by Borrower from time to time, GMAC will loan and advance Borrower the
principal amount of money so requested, up to the Line of Credit (hereinafter
the Credit Advance).  The aggregate principal amounts so loaned and advanced
and remaining unpaid from time to time shall be deemed to be Credit Line
Advances.  Each Credit Advance shall be disbursed by GMAC from its San Antonio,
Texas office and, upon such disbursement being made, shall be charged to
Borrower's account on GMAC's books and records.  GMAC will render to Borrower a
statement at least once each month of Borrower's account which shall constitute
an account stated and shall be presumed to be correct.

         Section 2.04  Repayment.  Borrower shall repay the Credit Line
Advances to GMAC together with all accrued and unpaid interest and applicable
costs and expenses as hereinafter set forth (hereinafter the Total Borrowing
Base Indebtedness).  Upon request made by GMAC, Borrower shall execute and
deliver such promissory note or notes in the form then in use by GMAC (being
hereafter referred to as the Borrowing Base Promissory Note) and guaranties to
further evidence the Credit Line Advances and related obligations; provided
that the failure of GMAC to so request or the failure of Borrower to execute
and deliver such Borrowing Base Promissory Note or Notes, or guaranty or
guaranties, shall not affect Borrower's obligation to





                                      -12-
<PAGE>   17





repay GMAC as herein set forth.  Any Borrowing Base Promissory Note or Notes,
or guaranty or guaranties, executed and delivered hereby shall be expressly
made subject to the terms and conditions of this Agreement.  GMAC may send
monthly statements to Borrower for the amount owed; if Borrower fails to
question or otherwise contest the information on such statements within 10 days
of receipt by Borrower, Borrower shall be deemed to agree with the information
on the statements, including the accuracy of GMAC's calculation of the amount
owed.

         (a)  Permissive Repayment.  Borrower may, at any time and without any
prepayment fee or premium or notice or penalty, repay all or any part of the
Credit Line Advances to GMAC.

         (b)  Mandatory Repayment.  The Total Borrowing Base Indebtedness shall
be repaid by Borrower to GMAC immediately and without further notice or demand
therefor by GMAC upon the earlier of the following occurrences:

                 (i)  an Event of Default, as hereinafter set forth, or

                 (ii)  the effective date of the termination of this Agreement
         as hereinafter set forth.

         Section 2.05  Interest.  The Credit Line Advances shall bear interest
on the unpaid principal amount of and from the date of each Credit Advance to
the date of repayment in full of the Credit Line Advances.  Only one interest
rate will apply to the Credit Line Advances at any given time.  Subject to the
provisions of the last sentence of this Section 2.05, the interest rate on each
Credit Line Advance will be determined from time to time at the Prime Rate plus
1.25 percentage points.  Interest shall be calculated on the basis of a 360-day
year for the number of actual days outstanding.  Interest shall be due and
payable monthly within 10 days of the billing date and the billing date shall
be within the first 5 Business Days of each month hereafter until Borrower have
paid GMAC all sums owing under this Agreement.  GMAC may offer, from time to
time at is sole discretion, a wholesale incentive program which allows for a
1.25 percentage point reduction in the interest rate, as outlined in Exhibit
2.05; if such a program is at any time in place and Rush elects to participate
in it, then Rush shall receive such 1.25 percentage point reduction on the
interest rate in its Credit Line Advances; provided, however, that GMAC shall
have the right to terminate or modify the program upon 30 days' notice.

         Section 2.06  Permitted Use of Credit Advances.  Each and every Credit
Advance by GMAC to Borrower or on Borrower's behalf may be used solely for the
purposes of: (a) holding or acquiring inventory consisting of the New Parts
Inventory by the Rush Group;





                                      -13-

(b) for general working capital purposes; and (c) for such other purposes
related to the business of the Rush Group as may be reasonably acceptable to

         Section 2.07  Collateral Formula Amount.  The Collateral Formula

         materials and all such goods constituting work in progress or as
         attachments or fixtures on other tangible property.  Except as set
         forth herein, "inventory" shall have the meaning attributed it by
         Section 9.109(4) of the Texas Business and Commerce Code.

         Net Book Value shall be the cost of an item of inventory as recorded in
         the books of account of the Rush Group plus or minus any adjustments
         made consistent with GAAP.  In the event of any dispute or
         disagreement as to the Net Book Value of an item or items of
         inventory, the judgment and decision of GMAC shall be final.

         as Exhibit 2.07 attached hereto.

Agreement), as

may be required by GMAC to grant and maintain a valid, perfected first lien or
security interest in the Borrowing Base Collateral.  The security agreements to

If an additional Dealer is formed in the future, such Dealer shall execute
similar documents required by GMAC granting to GMAC a security interest in the
Borrowing Base Collateral, conforming as necessary to the laws of the Dealer's

business;

         (d)     insure it against all risks in such amounts and with a carrier

property.

any Dealer are a party to any agreement which in the opinion of Borrowers does
or will materially and adversely affect the business, operations or condition,
financial or otherwise, of any Borrower.

in any material respect under the provisions of any instrument evidencing any
material obligation, indebtedness or liability of a Borrower or of any
agreement relating thereto, or under any order, writ, injunction, or decree of
any court, or in default under or in violation of any order, regulation, or
demand of any governmental instrumentality which default or violation might
have consequences which would have a Material Adverse Effect





                                      -24-
<PAGE>   29





affect on the business, financial condition, or properties of a Borrower.

         Section 5.15  Misrepresentation.  There is no fact which Borrower or
any Dealer have failed to disclose to GMAC, which materially and adversely
affects nor, so far as Borrower or any Dealer can now foresee, is reasonably
likely to have a Material Adverse Effect on the business, operation,
properties, profits, or condition of Borrower or any Dealer or the Collateral,
or the ability of Borrower or any Dealer to perform this Agreement.

Borrower and Dealers there is no Hazardous Material (defined above) on or in
any facility, owned, managed or occupied by Borrower or any Dealer located on

real estate adjoining any Facility is affected by Hazardous Material
contamination.  To the Best Knowledge of Borrower and Dealers, no report,

contamination exists on any Facility or identifying any Hazardous Material as
being located upon or released on or from any Facility.

Report submitted as of a month-end date shall have attached to it a complete

attached to Exhibit 2.07.  GMAC may, in its sole and absolute discretion,
increase the frequency of such reports and demand such a report at any time.

         Section 6.09  Inspection.  Rush Group will permit GMAC or its designee
to: (a) visit, at any time during normal business hours upon GMAC's request,
all premises where any Collateral, or any records or documents of any of the

Collateral and any records or documents of any of the Rush Group or which
relate to any Collateral; and (c) discuss their affairs, finances and accounts
with any director, officer, employee, accountant, partner, affiliate or agent
of any of the Rush Group.

         Section 6.10  Insurance: Payment of Premium.  Rush Group will, at
their sole cost and expense, keep and maintain their properties insured for
their full insurable value against loss or damage by fire, theft, explosion,
sprinklers and all other hazards and risks ordinarily insured against under all
risk policies in use by other owners or users of such properties in similar
businesses and notify GMAC promptly of any event or occurrence causing a
material loss or decline in value of its properties and the estimated (or
actual, if available) amount of such loss or decline.  All policies of
insurance on the Collateral will be in form and with insurers acceptable to
GMAC and all such policies will be in such amounts as may be satisfactory to
GMAC.  Rush Group will deliver to GMAC (i) the original (or certified copy) of
each policy of insurance or, in GMAC's sole, absolute discretion, a certificate
evidencing such insurance and (ii) evidence of payment of all premiums
therefor.  Such policies and certificates of insurance will contain an
endorsement, in form and substance acceptable to GMAC, showing loss payable to
GMAC.  Such endorsement, or an independent instrument furnished to GMAC,  will
provide that the insurance companies will give GMAC at least 30 days' prior
written notice before any such policy or policies of insurance will be altered
or canceled and that no act or default of Borrower, Dealers or any other person
shall affect the right of GMAC to recover under such policy or policies of
insurance in case of loss or damage and that GMAC will have the right to cure
any such default by such parties.  Rush





                                      -29-
<PAGE>   34





Group hereby directs all insurers under such policies of insurance where loss
or damage to Collateral exceeds $500,000 under any such policy of insurance to
pay all proceeds payable thereunder directly to GMAC.  So long as no Event of
Default exists hereunder, at the option of Rush Group, in the case of insurance
proceeds arising from the loss or damage of improvements to Rush Group's real
or personal property, the proceeds may be used to replace or restore same with
property having equal or greater value and utility to that lost or destroyed;
provided, however, Rush Group shall at its expense furnish to GMAC evidence
satisfactory to GMAC (including without limitation, title insurance policies or
endorsements thereto and opinions of counsel) that GMAC has a valid, duly
perfected lien on such property of equal or superior priority to the lien in
the property so replaced or restored.  To the extent not so used, all such
proceeds shall be applied as a partial prepayment of the Loans.  Borrower and
each Dealer irrecoverably makes, constitutes and appoints GMAC (and all
officers, employees or agents designated by GMAC) as its true and lawful
attorney (and agent-in- fact), effective from and after the occurrence of an
Event of Default, for the purpose of making, settling and adjusting claims
under such policies of insurance, endorsing the name of Borrower or any Dealer
on any check, draft, instrument or other item or payment for the proceeds of
such policies of insurance (which, in GMAC's sole discretion, shall either be
used towards the repair, restoration or replacement of the Collateral, or the
satisfaction of Borrower's obligations hereunder), and for making all
determinations and decisions with respect to such policies of insurance.  In
the event Borrower or any Dealer, at any time or times hereafter, fails to
obtain or maintain any of the policies of insurance required above or to pay
any premium in whole or in part relating thereto, then GMAC, without waiving or
releasing any obligation or default by Rush Group hereunder, may (but will be
under no obligation to) at any time or times thereafter obtain and maintain
such policies of insurance and pay such premiums and take any other action with
respect thereto which GMAC deems advisable.  All sums so disbursed by GMAC,
including reasonable attorneys' fees,  court costs, expenses and other charges
relating thereto, will be payable, on demand, by Rush Group to GMAC, will bear
interest until paid in full at the interest rate per annum equal to the Prime
Rate plus 1.00 percentage point (subject, if applicable, to the 1.00 percentage
point reduction under the wholesale incentive program described above) and will
be additional indebtedness hereunder secured by the Collateral.  In addition,
Rush Group will obtain and maintain in full force and effect policies of
liability, workers compensation and business interruption insurance in amounts
at least equal to that customarily carried by persons or entities conducting
comparable businesses.

any Laws having to do with the removal of Hazardous Material.  Within 30 days
after

                 (iv)     Immediately advise GMAC in writing upon Rush Group's
         discovery or any discovery by their Agents of any occurrence or
         condition on any real property adjoining or in the vicinity of any
         Facility which does, or could, cause the Facility, or any part
         thereof, to contain Hazardous Material or otherwise be in violation of
         any Hazardous Material Laws or cause the Facility to be subject to any
         restrictions on the ownership, occupancy, transferability or use
         thereof under any Hazardous Material Laws.  Nothing in this Section
         6.11(c)(iv) is intended or shall operate to create a duty on the part
         of Rush Group or any of its Agents to inquire as to the condition
         (environmental or otherwise) of any property not owned or leased by
         Rush Group.

         (d)  GMAC will have the right, but not the obligation, to cause all
Hazardous Material and Hazardous Material contamination found on or in any
Facility (except that used in the ordinary course of Rush Group's business) to
be removed therefrom or remediated on site if cost effective and permitted by
law.  In such





                                      -32-
<PAGE>   37





event, the cost of the removal or remediation, including all expenses, charges,
and fees incurred by any GMAC in connection therewith, including attorneys',
engineers', and consultants' fees, shall be payable by Rush Group on demand.
Rush Group will give to GMAC and its Agents access to the Facility for such
purposes and Rush Group hereby grant to GMAC and its Agents full right and
authority to remove any such Hazardous Material and Hazardous Material
contamination from the Facility or to remediate it on site if cost effective
and permitted by law.

         (e)  If at any time during the term of any Loan, GMAC has reasonable
cause to believe that an environmental condition in violation of Section 5.16
above exists (other than in the ordinary course of Rush Group's business), GMAC
may notify Rush Group in writing that it desires a site assessment or
environmental audit ("Audit") of any or all Facility(s) to be made, and at any
time thereafter cause such Audit to be made of the Facility(s) at Rush Group's
sole expense.  Such Audit(s) will be performed in a manner reasonably
calculated to confirm and verify compliance with the provisions of this Section
6.11.  Rush Group will reasonably cooperate with the persons conducting the
Audit to allow entry and reasonable access to all portions of the Facility(s)
for the purpose of the Audit(s), to supply the auditors with all available
historical and operational information regarding the Facility(s), as may
reasonably be requested by the auditors, and to make available for meetings
with the auditors appropriate personnel having knowledge of matters relevant to
the Audit(s).  Rush Group will comply, at their sole cost and expense, with all
recommendations contained in the Audit(s) to the extent necessary to bring Rush
Group into compliance with the other provisions of the Section 6.11, including
any recommendations for additional testing and studies to detect the presence
of Hazardous Material, or to otherwise confirm and verify Rush Group's
compliance with the provisions of this Section, to the extent required by GMAC.

         (f)  The representations and obligations of Rush Group under this
Section 6.11 shall, with respect to each tract or parcel of real property
constituting the Real Estate, remain in effect until GMAC releases its liens in
any applicable part of the Real Estate; upon such release, the obligations
shall cease only as to that portion of the Real Estate released.  Without
limiting the foregoing, it is expressly understood that if, for example, GMAC
becomes the owner of any part of the Real Estate through foreclosure, deed in
lieu of foreclosure or otherwise, all obligations of Rush Group under this
Section 6.11 shall remain in full force and effect.

         Section 6.12  Indemnification.  Rush Group will defend, indemnify and
hold GMAC (including the successors, assigns, employees, agents, officers and
directors of GMAC) harmless from and against any and all actions, claims,
losses, liabilities,





                                      -33-
<PAGE>   38





damages and expenses (including, without limitation, cleanup costs and
reasonable attorneys' fees) arising from or relating to any breach of any
covenants, agreements or obligation arising under this Agreement or any
inaccuracy of or omission from any representation or warranty of Rush Group set
forth in this Agreement, including without limitation, those arising directly
or indirectly from, or relating, to the handling, manufacture, transport,
storage, treatment, emission, spill, leak, dump or disposal of any Hazardous
Material by or in respect of Rush Group or any Collateral.  This indemnity will
apply notwithstanding any negligent or other contributory conduct by or on the
part of GMAC (except to the extent the actions, claims, losses, liabilities,
damages or expenses are solely attributable to the gross negligence or willful
or wanton misconduct of GMAC) or any one or more other persons or entities, and
will be enforceable notwithstanding any attempts by Rush Group to exercise due
diligence.  The loss, liability, damage, cost or expense which is covered by
this indemnity will include, without limitation, all foreseeable consequential
damages; the costs of any required or necessary repair, cleanup or
detoxification of any Facility, including the soil and ground water thereof,
and the preparation and implementation of any closure, remedial or other
required plans; damage to any natural resources; and all reasonable costs and
expenses incurred by GMAC in connection with the above, including but not
limited to, attorneys' and consultants' fees.  The provisions of this Section
6.12 will survive repayment of the Loans or other obligation to GMAC in full
and expiration or termination of this Agreement.

         Section 6.13  Further Assurances.  At its costs and expense, upon
request of GMAC, Rush Group will duly execute and deliver or cause to be duly
executed and delivered, to GMAC such further instruments, documents,
certificates, financing and continuation statements, and do and cause to be
done such further acts that may be reasonably necessary or advisable in the
opinion of GMAC to carry out more effectively the provisions and purposes of
this Agreement and the other Loan Documents.

         Section 6.14  Future Dealers.  In the event any future entity formed
by Rush becomes a "Dealer" subject to the terms of this Agreement, such new
Dealer shall execute a Guaranty Agreement on a form acceptable to GMAC
conforming to the laws of the state where that Dealer does business.  Rush
shall also execute a Guaranty Agreement of any obligations of the Dealers
pursuant to this Agreement, including without limitation any Wholesale Floor
Plan Loans made to Dealers under Article IV.  From time to time GMAC may
require members of the Rush Group to execute such acknowledgments, consents,
revised guaranty agreements and the like to affirm and ratify the obligations
of each member of the Rush Group for the payment and performance of all
Obligations hereunder.

control of GMAC against any amount owing by Rush Group to GMAC;

         (c)     with respect to accounts, contract rights, chattel paper, tax
refunds and general intangibles constituting Collateral herein, GMAC:

                 (i)  may settle, adjust and compromise all present and future
         claims arising thereunder or in connection therewith;

                 (ii)  may sell, assign, pledge or make any other agreement
         with respect thereto or the proceeds thereof;

         of any instrument so endorsed;

                 (v)  is hereby constituted and appointed by Borrower and

agreement executed now or in the future: sell or lease the Collateral, or any

                                      -42-
<PAGE>   47





of sale, and GMAC is empowered to make successive sales under such power until
all of the Collateral shall be sold; the liens, security interests and rights
hereunder shall remain in full force and effect as to the unsold portion of the

repossessed by GMAC to the original seller thereof, or to any person designated
by such seller, at the invoice cost thereof to Rush Group less any credits
granted to Rush Group with respect thereto and reasonable costs of
transportation and reconditioning, shall be deemed to be a commercially
reasonable means of disposing of the same.  Rush Group further agree that if
GMAC shall solicit bids from three or more other sellers or dealers in the type
of property repossessed by GMAC hereunder, any sale by GMAC of such property in
bulk or in parcels to the bidder submitting the highest cash bid therefor also
shall be deemed to be a commercially reasonable means of disposing of the same.
Notwithstanding the foregoing, it is expressly understood that such means of
disposal shall not be exclusive, and that GMAC shall have the right to dispose
of any property repossessed hereunder by any commercially reasonable means.

         Section 10.03  Remedies Cumulative.  GMAC shall have all rights and
remedies contained in any other Loan Document, all of which rights and remedies
shall be cumulative of those granted herein, or otherwise available at law or

the Uniform Commercial Code applicable in any particular state.

         Section 10.04  Expenses.  Rush Group shall pay all expenses and
reimburse GMAC for any expenditures, including reasonable attorney fees and
legal expenses, in connection with GMAC's  exercise of any of its rights and
remedies under this Agreement.

other disposition of the Collateral, after payment of all expenses incurred by
GMAC in enforcing the Indebtedness or in retaking, holding, preparing for sale

Indebtedness in such manner as GMAC shall elect.

         Section 10.06  Default Interest.  In addition to the remedies provided
above or elsewhere in this Agreement, all Indebtedness which is not paid when
due, by acceleration, at maturity or otherwise, shall bear interest (i) in the
case of Indebtedness evidenced by promissory notes, at the default rate (if
any) provided in the applicable notes, and (ii) in the case of all Indebtedness
not covered by item (i), at the highest nonusurious default rate provided for
in any of the notes.

         Section 10.07  No Agency.  Nothing herein contained shall be construed
to constitute Borrower or any Dealer as agent of GMAC for any purpose
whatsoever, and GMAC shall not be responsible nor liable for any shortage,
discrepancy, damage, loss or destruction of any part of the Collateral wherever
the same may be located and regardless of the cause thereof, except to the
extent the same results from GMAC's own gross negligence or willful misconduct.
GMAC shall not, under any circumstances or in any event whatsoever, have any
liability for any error or omission or delay of any kind occurring in the
settlement, collection or payment of any of the Collateral or any instrument
received in payment thereof or for any damage resulting therefrom, except to
the extent the same results from GMAC's own gross negligence or willful
misconduct.   GMAC does not by anything herein or in any assignment or
otherwise, assume any of Rush Group's obligations under any contract or
agreement assigned to GMAC, and GMAC shall not be responsible in any way for
the performance by Rush Group of any of the terms and conditions thereof.

                                 MISCELLANEOUS

         Section 11.01  GMAC's Accounts.  GMAC shall maintain on its books in
accordance with its usual practice an account or accounts with respect to the
Loans, which account or accounts shall include, without limitation, (i) the
outstanding principal amount of each of the Loans, (ii) the amount of principal
and interest due under each of the Loans and the required payment dates, (iii)
all other fees, costs, expenses, losses and indemnities due under this
Agreement or any other Loan Document, and (iv) all amounts received by GMAC
with respect to the foregoing.  For purposes of any legal action or proceeding
arising out of or in connection with this Agreement or any other Loan Document,
and for all other purposes, the entries made in such account or accounts
maintained by GMAC pursuant to this Section shall create a presumption as to
the existence and amounts of the foregoing, absent manifest error.  However,
Rush Group shall have 30 days from the date the GMAC Account statement is
received to contest the accuracy of the statement; the failure of Rush Group to
contest the accuracy shall constitute conclusive evidence of its accuracy.  If
Rush Group contests the accuracy with





                                      -44-
<PAGE>   49





said 30 days, GMAC shall have 30 days to reconcile the disputed GMAC Account
balance.  The failure by GMAC to maintain such account or accounts shall not in
any manner affect the Indebtedness.

         Section 11.02  Notices.  All notices or other communications required
or permitted to be given pursuant to the provisions of this Agreement shall be
in writing and shall be considered as properly given if mailed by first class
United States mail, postage prepaid, registered or certified with return
receipt requested, or by delivering same in person to the intended addressee,
or by prepaid telegram, telex or telecopy.  Notice given in any other manner
shall be effective only if and when received by the addressee.  For purposes of

however, that either party shall have the right to change its address for

         Section 11.03  Waiver.  No course of dealing, or any failure by GMAC
to insist, or any election by GMAC not to insist, upon any of Rush Group's
strict performance of any of the terms, provisions or conditions of the Loan
Documents shall not be deemed to be a waiver of same or of any other term,
provision or condition thereof; and GMAC shall have the right at any time
thereafter to insist upon strict performance by Borrower or any Dealer of any
and all of same.  Specifically, no Advance by GMAC when there exists an Event
of Default under Article IX hereinabove shall in any way preclude GMAC from
thereafter declaring such failure to comply to be an Event of Default
hereunder.

         Section 11.04  Survival.  All agreements, representations, warranties
and covenants of Borrower and Dealers contained in this Agreement shall survive
the execution of this Agreement and the other Loan Documents, and the making of
the Loans; provided, however, that to the extent any agreement, representation,
warranty or covenant of Borrower or any Dealer herein, either by its express
terms or by the determination of a court of competent jurisdiction, survives
the repayment of the Loans and the expiration or termination of this Agreement,
such agreement, representation, warranty or covenant shall in no event survive
more than 2 years from the later of the (i) date of repayment of the Loans or
(ii) the expiration or termination of this Agreement.

         Section 11.05  Limitations on Interest.  All agreements between GMAC,
Borrower and Dealers, whether now existing  or hereafter arising and whether
written or oral, are hereby limited so that in no contingency, whether by
reason of demand for payment or acceleration of the maturity hereof or
otherwise, shall the interest contracted for, charged or received by GMAC
exceed the maximum amount permissible under applicable law.  If, from any
circumstance whatsoever, interest would otherwise  be payable to Lender in
excess of the maximum lawful amount, the interest payable to GMAC shall be
reduced to the maximum amount permitted under applicable law; and if from any
circumstance GMAC shall ever receive anything of value deemed interest by
applicable law in excess of the maximum lawful amount, an amount equal to any
excessive interest shall be applied to the reduction of the principal balance
of the Indebtedness and not to the payment of interest, or if such excessive
interest exceeds the principal balance such excess shall be refunded to
Borrower and/or Dealers, as applicable.  All interest paid or agreed to be paid
to GMAC shall, to the extent permitted by applicable law, be amortized,
prorated, allocated, and spread throughout the full period until payment in
full of the principal so that the interest hereon for





                                      -46-
<PAGE>   51





such full period shall not exceed the maximum amount permitted by applicable
law.  This paragraph shall control all agreements between GMAC, Borrower and
Dealers.

         Section 11.06  Applicable Law.  This Agreement and the other Loan
Documents (except as may be otherwise expressly provided in such other Loan
Documents), shall be governed by and construed in accordance with the laws of
the State of Texas and the laws of the United States applicable to transactions
within such State.  The Guaranty Agreements, Security Agreements or other Loan
Documents (except this Agreement) executed by a Dealer or Guarantor doing
business in a state other than Texas, or granting a lien on collateral located
in a state other than Texas, shall be governed by the laws of the state
specified in such documents.

         Section 11.07  Venue and Waiver of Jury Trial.  The parties agree that
all actions or proceedings arising in connection with this Agreement and any of
the Loan Documents shall be tried and litigated only in the state and federal
courts located in the State of Texas or, at the sole option of GMAC, in any
other court in which GMAC shall initiate legal or equitable proceedings and
which has subject matter jurisdiction over the matter in controversy.  All the
parties to this Agreement waive any right each may have to assert the doctrine
of forum non conveniens or to object to venue to the extent any proceeding is
brought in accordance with this Section 11.07.  All the parties to this
Agreement hereby further jointly and severally waive any right to trial by jury
with respect to any action, claim, suit or proceeding in respect of or relating
to this Agreement or any other Loan Document and/or any relationship between
GMAC and Rush Group.

         Section 11.08   Severability.  If any provision hereof or of any of
the other Loan Documents or the application thereof to any person or
circumstance shall, for any reason and to any extent, be invalid or
unenforceable, neither the application of such provision to any other person or
circumstance nor the remainder of the instrument in which such provision is
contained shall be affected thereby, but rather shall be enforced to the
greatest extent permitted by law.

         Section 11.09  Construction.  This Agreement and each other Loan
Document are being entered into by competent and experienced businessmen,
represented by counsel, and the parties acknowledge that each party and its
counsel have reviewed and revised this Agreement and the Loan Documents;
therefore, the normal rule of construction to the effect that any ambiguities
are to be resolved against the drafting party shall not be employed in the
interpretation of this Agreement, the Loan Documents or any amendments or
exhibits hereto.  The parties intend that all Loan Documents shall be construed
and interpreted in a consistent manner.

         Section 11.10  GMAC's Discretion.  In any instance hereunder
(including any exhibits, schedules, annexes or addenda hereto) where GMAC's
satisfaction, approval or consent or the exercise of GMAC's judgment is
required, the granting or denial of such satisfaction, approval or consent and
the exercise of such judgment shall be within the sole discretion of GMAC.
This provision shall govern any such satisfaction requirements, consents,
approvals or exercise of judgment required in connection with any of the Loan
Documents.

         Section 11.11  No Third Party Beneficiary.  This Agreement is for the
sole benefit of GMAC and Rush Group and is not for the benefit of any third
party.

         Section 11.12  Rush Group In Control; No Partnership.  In no event
shall GMAC's rights and interests under the Loan Documents be construed to give
GMAC the right to, or be deemed to indicate that GMAC is in control of the
business, management or properties of Rush Group or has power over the daily
management functions and operating decisions made by Rush Group.  Nothing
contained herein or in any of the other Loan Documents shall be construed as
creating joint venture, partnership, tenancy-in-common or joint tenancy
arrangement between GMAC and Rush Group.  The relationship of GMAC and Rush
Group is and at all times shall be solely that of debtor and creditor.

         Section 11.13  Successors and Assigns.  This Agreement shall be
binding upon and inure to the benefit of the parties hereto and their
respective heirs, successors, legal representatives and assigns.  However,
Borrowers shall not assign or encumber this Agreement or any rights herein, it
being expressly understood and agreed that Rush Group's rights hereunder are
not assignable.

         Section 11.14  Number and Gender.  Whenever used herein, the singular
number shall include the plural and the plural the singular, and the use of any
gender shall be applicable to all genders.  The duties, covenants, obligations,
and warranties of Borrower and Dealers in this Agreement shall be joint and
several obligations of Borrower and of each Dealer if more than one.

         Section 11.15  Captions.  The captions, headings, and arrangements
used in this Agreement are for convenience only and do not in any way affect,
limit, amplify, or modify the terms and provisions hereof.

         Section 11.16  Time of the Essence.  Time is of the essence with
respect to each and every matter pertaining to performance under this Agreement
and of each provision hereof.

         Section 11.17  Executed Copies.  This Agreement may be executed in any
number of counterpart copies, each of which counterparts shall be deemed an
original for all purposes.

         Section 11.18  Entire Agreement of the Parties.  This Agreement,
including all agreements referred to or incorporated herein and all recitals
hereto, is the entire agreement among the parties relating to the subject
matter hereof, supersedes all prior agreements, commitments and understandings
among the parties hereto relating to the subject matter hereof, and cannot be
changed or terminated orally, and shall be deemed effective as of the date
hereof.  To the extent that the terms of the documents heretofore evidencing
the Borrowing Base Loans, Oklahoma Real Estate Loan, Texas Real Estate Loans or
Wholesale Floor Plan Loans are inconsistent with the terms hereof, or if any
contemporaneous or subsequent documents evidencing said loans are inconsistent
with the terms hereof, the terms of this Agreement shall control.

         Section 11.19  Statutory Notice.  In accordance with Section 26.02 of
the Texas Business and Commerce Code, GMAC hereby notifies Rush Group that:

                 THIS WRITTEN LOAN AGREEMENT REPRESENTS THE FINAL AGREEMENT

               [GENERAL MOTORS ACCEPTANCE CORPORATION LETTERHEAD]



                                 June 25, 1998

Mr. W. Marvin Rush
Rush Enterprises, Inc.

San Antonio, Texas  78219

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 and certain floating rate loans. This special
rate is offered for competitive reasons as an incentive to encourage dealers to
provide GMAC with continued wholesale financing. It is known as the Wholesale
Incentive Plan ("WIP").


This letter confirms GMAC's agreement to provide you with a WIP. The following
sets forth the percent reduction which GMAC will provide you below the standard
rate of interest we have been charging for your new and used wholesale floor
plan financing, dealer real-estate loans and Borrowing Base Line of Credit. All
wholesale, dealer real-estate loans and Borrowing Base Line of Credit will be at
prime. Existing rates: prime (wholesale); prime plus 1.00p.p. (all dealer
real-estate loans); prime plus 1.25p.p. (Borrowing Base Line of Credit).

Minimum wholesale outstandings must total at least $20 million and GMAC must
retain all current wholesale and dealer loan outstandings for the Rush
dealership franchises presently owned and in the future. GMAC must also be
provided first right of refusal on all future loans and wholesale financing.

The WIP becomes effective as of July 1, 1996. 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 ninety (90) 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.

The undersigned hereby certifies that as of the date hereof, the above
information and attached balance sheets (and parts inventory schedules - for
aduits only) of the Rush Truck Group are true and correct and that there exists
no default under the Loan Agreement.
The Monthly Certification Report of Borrower shall be subject to GMAC's
approval. No failure by GMAC to provide notice of approval or notice of
disapproval shall limit or constitute a waiver of any of the rights or remedies
of GMAC hereunder or under any other loan document. Notwithstanding anything
herein to the contrary and notwithstanding that GMAC may have previously
approved any parts and accessories for Inclusion in the Collateral Formula
Amount at a specified value, GMAC may, at any time and from time to time,
revalue any parts and accessories included in the Collateral Formula Amount.
Incident to any such revaluation, the Borrower shall promptly provide to GMAC
any materials GMAC may reasonably require. GMAC, in its sole and absolute
discretion, may determine as a result of any such revaluation to reduce the
amount which any parts and accessories contributes to the Collateral Formula
Amount or to exclude such amount of any parts and accessories entirely, which
determination shall be conclusive and binding in the absence of manifest error.
If GMAC so determines that the Collateral Formula Amount of Borrower is to be
reduced, GMAC shall give written notice thereof to the Borrower stating the
amount of the reduction, the nature of the action taken by GMAC, and the
reduction shall be effective upon GMAC's issuance of that notice.

                  written notice to Seller within such thirty (30) day period
                  shall be deemed acceptance by Purchaser). If Purchaser objects
                  as provided above and if Seller does not agree with
                  Purchaser's objections, if any (it being agreed that the
                  failure of Seller to deliver written notice to the Purchaser
                  of Seller's disagreement with Purchaser's objections within
                  thirty (30) days of Seller's receipt of Purchaser's objections
                  shall be deemed acceptance by Seller), or such objections are
                  not resolved on a mutually agreeable basis within thirty (30)
                  days after Seller's receipt of Purchaser's objections, any
                  such disagreement shall be promptly submitted to a mutually
                  acceptable "big-six" accounting firm that has no affiliation
                  with any of Purchaser, Seller or the Company (the
                  "UNAFFILIATED FIRM"). The Unaffiliated Firm shall resolve
                  within thirty (30) days after said Unaffiliated Firm's
                  engagement by the parties the differences regarding the
                  Closing Date Balance Sheet in accordance with generally
                  accepted accounting principles consistently applied and this
                  Agreement. The decision of such Unaffiliated Firm shall be
                  final and binding upon, and its fees, costs and expenses shall
                  be shared equally by, Seller and Purchaser. Seller and
                  Purchaser shall each bear the fees, costs and expenses of its
                  own accountants. Upon resolution of any such dispute, the
                  determination of the Closing Date Balance Sheet shall be
                  deemed to be final.

                           (d) If the Closing Date Balance Sheet as finally
                  determined pursuant to this Section 2.3 shows that
                  stockholders' equity is less than $8,600,000, then the
                  purchase price shall be reduced through the return to
                  Purchaser of cash in an amount equal to the difference between
                  $8,600,000 and the amount of stockholders' equity of the
                  Company as reflected on the Closing Date Balance Sheet. Such
                  amount shall be promptly returned by wire transfer of
                  immediately available funds to Purchaser. If the Closing Date
                  Balance Sheet as finally determined pursuant to this Section
                  2.3 shows that stockholders' equity is greater than
                  $8,600,000, then the purchase price shall be increased through
                  the prompt payment to Seller of cash in an amount equal to 50%
                  of the difference between $8,600,000 and the amount of
                  stockholders' equity of the Company as reflected on the
                  Closing Date Balance Sheet. Such amount shall be paid by wire
                  transfer of immediately available funds to

                  Seller. If the Closing Date Balance Sheet as finally
                  determined pursuant to this Section 2.3 shows that
                  stockholders' equity is equal to $8,600,000, no adjustment to
                  the Purchase Price shall be made.

                           (e) From and after the Closing, the Company shall use
                  its best efforts to sell any inventory reduced in value
                  pursuant to Section 2.3(a) and to collect any accounts
                  receivable excluded pursuant to Section 2.3(b) and shall
                  promptly pay to Seller by wire transfer of immediately
                  available funds 50% of the proceeds of such sale in excess of
                  the reduced value and 50% of the proceeds of such collection;
                  provided, however, that the Company may, at its option, at any
                  time transfer any of such inventory and accounts receivable to
                  Seller and shall have no further obligation under this Section
                  2.3(e) with respect to the inventory and accounts receivable
                  so transferred.

         3.       Representations and Warranties Concerning the Company.

         Seller represents and warrants to Purchaser and Rush that the
statements contained in this Article 3 are correct and complete as of the date
of this Agreement and will be correct and complete as of the Closing Date (as
though made then and as though the Closing Date were substituted for the date of
this Agreement throughout this Article 3), except as set forth in the disclosure
schedule delivered by Seller to Purchaser on the date hereof and initialed by
the Parties (the "Disclosure Schedule"). Nothing in the Disclosure Schedule
shall be deemed adequate to disclose an exception to a representation or
warranty made herein, however, unless the Disclosure Schedule identifies the
exception with reasonable particularity and describes the relevant facts in
reasonable detail. Without limiting the generality of the foregoing, the mere
listing (or inclusion of a copy) of a document or other item shall not be deemed
adequate to disclose an exception to a representation or warranty made herein
(unless the representation or warranty has to do with the existence of the
document or other item itself). The Disclosure Schedule will be arranged in
paragraphs corresponding to the lettered and numbered paragraphs contained in
this Article 3.

                  3.1  Organization, Etc. The Company is a corporation duly
         organized, validly existing and in good standing under the laws of the
         State of Texas and has full corporate power and authority to conduct
         its business as it is now being conducted and to own, operate or lease
         the properties and assets it currently owns, operates or holds under
         lease. The Company is duly qualified or licensed to do business and is
         in good standing as a foreign corporation in each jurisdiction where
         the character of its business or the nature of its properties makes
         such qualification or licensing necessary, all of which jurisdictions
         are set forth on the Disclosure Schedule. The Company has heretofore
         delivered to Purchaser true and correct copies of its Certificate of
         Incorporation and By-laws as in effect on the date hereof. The minute
         books (containing the records of meetings of the stockholders, the
         board of directors, and any committees of the board of directors), the
         stock certificate books, and the stock record books of the Company are
         correct and complete.

                  3.2  Subsidiaries. The Company does not have, directly or
         indirectly, any legal or beneficial interest in any Subsidiary,
         partnership, joint venture or other entity.

                  3.3  Capitalization. The authorized, issued and outstanding
         capital stock of the Company is as set forth on the Disclosure
         Schedule. All of the issued and outstanding shares of capital stock of
         the Company are owned, of record and beneficially, by Seller. No Person
         other than Seller is or will be entitled to receive any payment with
         respect to the Company Stock. On the Closing Date, no shares of Company
         Stock will be held as treasury shares. The designations, powers,
         preferences, rights, qualifications, limitations and restrictions in
         respect of each class and series of authorized capital stock of the
         Company are as set forth in the Company's Certificate of Incorporation,
         and all such designations, powers, preferences, rights, qualifications,
         limitations and restrictions are valid, binding and enforceable and in
         accordance with all applicable laws. All outstanding shares of capital
         stock of the Company have been duly authorized and validly issued and
         are fully paid and non-assessable. All of the outstanding securities of
         the Company were issued in compliance with all applicable Federal and
         state securities laws. None of such outstanding securities has been
         issued in violation of any preemptive rights, rights of first refusal
         or similar rights. There are no outstanding options, warrants,
         convertible securities, calls, rights, commitments, preemptive rights
         or agreements or instruments or understandings of any character to
         which the Company is a party or by which the Company is bound,
         obligating the Company to issue, deliver or sell, or cause to be
         issued, delivered or sold, contingently or otherwise, additional shares
         of its capital stock or any securities or obligations convertible into
         or exchangeable for such shares or to grant, extend or enter into any
         such option, warrant, convertible security, call, right, commitment,
         preemptive right or agreement. There are no outstanding obligations,
         contingent or other, of the Company to purchase, redeem or otherwise
         acquire any shares of its capital stock. There are no voting trust
         agreements or other contracts, agreements, arrangements, commitments,
         plans or understandings restricting or otherwise relating to voting,
         dividend or other rights with respect to the capital stock of the
         Company.

                  3.4  Authorization. The Company has all requisite corporate
         power and authority to enter into this Agreement and each of the other
         agreements contemplated hereby, to carry out its obligations under this
         Agreement and each of the other agreements contemplated hereby and to
         consummate the transactions contemplated hereby and thereby. The
         execution and delivery of this Agreement, the consummation of the
         transactions contemplated hereby and the performance by the Company of
         its obligations hereunder have been duly authorized by all necessary
         corporate action on the part of the Company. This Agreement has been
         duly executed and delivered by the Company and constitutes the legal,
         valid and binding obligation of the Company, enforceable against the
         Company and in accordance with its terms (except as the enforceability
         thereof may be limited by any applicable bankruptcy, insolvency or
         other laws affecting creditors' rights generally or by general
         principles of equity, regardless of whether such enforceability is
         considered in equity or at law).

                  3.5  No Violation. The execution and delivery of this
         Agreement by the Company does not, and the consummation by the Company
         of the transactions contemplated hereby and compliance with the terms
         hereof will not, (a) conflict with, or result in any violation of or
         default or loss of any benefit under, any provision of the Company's
         Certificate of Incorporation or By-laws; (b) conflict with, or result
         in any violation of or default or loss of any benefit under, any
         permit, concession, grant, franchise, law, rule or regulation, or any
         judgment, decree or order of any court or other governmental agency or
         instrumentality to which the Company is a party or to which any of its
         property is subject; (c) conflict with, or result in a breach or
         violation of or default or loss of any benefit under, or accelerate the
         performance required by, the terms of any agreement, contract,
         indenture or other instrument to which the Company is a party or to
         which any of its property is subject, or constitute a default or loss
         of any right thereunder or an event which, with the lapse of time or
         notice or both, might result in a default or loss of any right
         thereunder or the creation of any Security Interest upon any of the
         assets or properties of the Company; or (d) result in any suspension,
         revocation, impairment, forfeiture or non-renewal of any Company
         License.

                  3.6  Approvals. The execution and delivery of this Agreement
         and the consummation of the transactions contemplated hereby by the
         Company will not require the consent, approval, order or authorization

         under any statute, law, rule, regulation, permit, license, agreement,
         indenture or other instrument to which the Company or Seller is a party
         or to which any of its or their properties are subject, and no
         declaration, filing or registration with any Governmental Entity or
         Regulatory Authority is required or advisable by the Company or Seller
         in connection with the execution and delivery of this Agreement, the
         consummation of the transactions contemplated hereby, or the
         performance by each of the Company and Seller of its or their
         respective obligations hereunder.

                  3.7  Financial Statements and Other Information.

                       (a) Seller has delivered to Purchaser (i) true, correct
                  and complete copies of the audited consolidated balance sheets
                  of the Company as of April 30, 1997 and 1996, and the related
                  statements of operations, retained earnings and cash flows
                  (together with the auditors' reports thereon) for each of the
                  years in the three year period ended April 30, 1997, together
                  with notes to such financial statements (the "Audited
                  Financial Statements") and (ii) true, correct and complete
                  copies of the unaudited balance sheets of the Company as of
                  December 31, 1997, and the related statements of operations
                  and cash flows for the eight-month period ended December 31,
                  1997 (the "Interim Financial Statements"). The Audited
                  Financial Statements and Interim Financial Statements are
                  herein collectively referred to as the "Financial Statements".

                       (b) The Financial Statements are in accordance with the
                  books and records of the Company and have been prepared in
                  accordance with generally accepted accounting principles
                  consistently applied throughout



                                       12

                  the periods covered thereby, and the balance sheets included
                  therein present fairly as of their respective dates the
                  financial condition of the Company (subject, in the case of
                  Interim Financial Statements, to year-end adjustments that may
                  be required upon audit, which adjustments will not have a
                  Material Adverse Effect on such financial statements). All
                  liabilities and obligations, whether absolute, accrued,
                  contingent or otherwise, whether direct or indirect, and
                  whether due or to become due, which existed at the date of
                  such Financial Statements have been disclosed in the balance
                  sheets included in the Financial Statements or in notes to the
                  Financial Statements to the extent such liabilities were
                  required, under generally accepted accounting principles, to
                  be so disclosed. The statements of operations, retained
                  earnings and cash flows included in the Financial Statements
                  present fairly the results of operations and cash flows of the
                  Company for the periods indicated (subject, in the case of
                  Interim Financial Statements, to year-end adjustments that may
                  be required upon audit, which adjustments will not have a
                  Material Adverse Effect on such financial statements), and the
                  notes included in the Financial Statements present fairly the
                  information purported to be shown thereby. The statements of
                  operations included in the Financial Statements do not contain
                  any items of special or non-recurring income or other income
                  not earned in the ordinary course of business except as
                  expressly specified therein.

                       (c) All properties and tangible assets reflected in the
                  latest balance sheet included in the Financial Statements have
                  a fair market or realizable value at least equal to the value
                  thereof as reflected therein. Purchaser acknowledges that
                  certain personal property located on the premises of the
                  Company is owned by Seller, all of which property is
                  designated as such on the Disclosure Schedule. Purchaser
                  further acknowledges that certain rebates identified as such
                  on the Disclosure Schedule, if received by the Company within
                  nine months after the Closing Date, shall be paid to Seller as
                  a commission.

                       (d) The accounts receivable of the Company, net of
                  applicable allowances in accordance with generally accepted
                  accounting principles consistently applied, as set forth on
                  the latest balance sheet included in the Financial Statements
                  or arising since the date thereof are valid and genuine; have
                  arisen solely out of bona fide sales and deliveries of goods,
                  performance of services and other business transactions in the
                  ordinary course of business consistent with past practice; are
                  not subject to valid defenses, set-offs or counterclaims; and
                  are collectible at the full recorded amount thereof over the
                  period of usual trade terms (by use of the Company's normal
                  collection methods without resort to litigation or reference
                  to a collection agency). The Company has fully performed all
                  obligations with respect thereto which they were obligated to
                  perform to the date hereof. Seller has delivered to Purchaser
                  an aging schedule for the accounts receivable as of December
                  31, 1997.

                       (e) The books, records and accounts of the Company
                  maintained with respect to its business accurately and fairly
                  reflect, in reasonable detail, the transactions and their
                  assets and liabilities with respect to their business. The
                  Company has not engaged in any transaction with respect to its
                  business, maintained any bank account for its business or used
                  any of its funds in the conduct of its business except for
                  transactions, bank accounts and funds which have been and are
                  reflected in its normally maintained books and records.

                       (f) Since April 30, 1997, there has been (i) no adverse
                  change in the assets or liabilities, or in the business or
                  condition, financial or otherwise, or in the results of
                  operations or prospects, of the Company, whether as a result
                  of any legislative or regulatory change, revocation of any
                  license or right to do business, fire, explosion, accident,
                  casualty, labor trouble, flood, drought, riot, storm,
                  condemnation or act of God or otherwise, and (ii) to the best
                  Knowledge of the Company and Seller, no fact or condition
                  exists or is contemplated or threatened which could reasonably
                  be anticipated to cause such a change in the future.

                  3.8  No Undisclosed Liabilities. Except as set forth in the
         notes to the Financial Statements, the Liabilities on the latest
         balance sheet included in the Financial Statements consist solely of
         accrued obligations and Liabilities incurred by the Company in the
         ordinary course of its business to Persons which are not Affiliates of
         the Company. There are no Liabilities of the Company of any kind
         whatsoever, whether or not accrued and whether or not contingent or
         absolute, determined or determinable or otherwise, including without
         limitation documentary or standby letters of credit, bid or performance
         bonds, or customer or third party guarantees, and no existing
         condition, situation or set of circumstances that could reasonably
         result in such a Liability, other than (i) Liabilities disclosed in the
         Financial Statements or (ii) Liabilities which have arisen after April
         30, 1997 in the Ordinary Course of Business and consistent with past
         practice (none of which is a Liability for breach of contract, breach
         of warranty, tort, infringement claim or lawsuit). There are no
         asserted claims for indemnification by any Person against the Company
         under any law or agreement or pursuant to the Company's Certificate of
         Incorporation or By-laws and the Company is not aware of any facts or
         circumstances that might reasonably give rise to the assertion of such
         a claim against the Company thereunder.

                  3.9  Corporate Action. All corporate action of the Board of
         Directors and of the stockholders of the Company taken on or prior to

                  3.11     Taxes.

                           (a) The Company has filed all Tax Returns that it was
                  required to file (taking into account all extensions). All
                  such Tax Returns and the information and data contained
                  therein have been properly and accurately compiled and
                  completed, fairly present the information purported to be
                  shown therein and reflect all Liabilities for Taxes for the
                  periods covered by such Tax Returns. All Taxes owed by the
                  Company (whether or not shown on any Tax Return) have been
                  paid. The Company currently is not the beneficiary of any
                  extension of time within which to file any Tax Return. No
                  claim has ever been made by an authority in a jurisdiction
                  where the Company does not file Tax Returns that it is or may
                  be subject to taxation by that jurisdiction. There are no
                  Security Interests on any of the assets of the Company that
                  arose in connection with any failure (or alleged failure) to
                  pay any Tax.

                           (b) The Company has withheld and paid all Taxes
                  required to have been withheld and paid in connection with
                  amounts paid or owing to any employee, independent contractor,
                  creditor, stockholder or other third party.

                           (c) No Seller or director or officer (or employee
                  responsible for Tax matters) of the Company expects any
                  authority to assess any additional Taxes for any period for
                  which Tax Returns have been filed. There is no dispute or
                  claim concerning any Tax Liability of the Company either (i)
                  claimed or raised by any authority in writing or (ii) as to
                  which Seller or the Company has Knowledge based upon personal
                  contact with any agent of such authority. The Disclosure
                  Schedule lists all federal, state, local and foreign income
                  Tax Returns filed with respect to the Company for taxable
                  periods ended on or after April 30, 1995, indicates those Tax
                  Returns that have been audited, and indicates those Tax
                  Returns that currently are the subject of audit. Seller has
                  delivered to Purchaser correct and complete copies of all
                  federal income Tax Returns, examination reports, and
                  statements of deficiencies assessed against or agreed to by
                  the Company since April 30, 1995.

                           (d) The Company has not waived any statute of
                  limitations in respect of Taxes or agreed to any extension of
                  time with respect to a Tax assessment or deficiency.

                  341(f) of the Code concerning collapsible corporations. The
                  Company has not made any payments, is obligated to make any
                  payments, or is a party to any agreement that under certain
                  circumstances could obligate it to make any payments that will

                  Code. The Company has disclosed on their federal income Tax
                  Returns all positions taken therein that could give rise to a
                  substantial understatement of federal income Tax within the
                  meaning of Section 6662 of the Code. The Company is not a
                  party to any Tax allocation or sharing agreement. The Company
                  (i) has not been a member of an affiliated group (within the
                  meaning of Section 1504 of the Code) filing a consolidated

                  the Taxes of any Person (other than the Company) under Treas.
                  Reg. ss.1.1502-6 (or any similar provision of state, local or
                  foreign law), as a transferee or successor, by contract or
                  otherwise.

                           (f) All elections and consents with respect to any
                  Tax (or the computation thereof) affecting the Company as of
                  the date hereof are obvious from the Tax Returns or are set
                  forth on the Disclosure Schedule. After the date hereof, no
                  election or consent with respect to any Tax (or the
                  computation thereof) affecting the Company will be made
                  without the written consent of Purchaser. The Company has not
                  agreed to make or is required to make any adjustment under
                  Section 481(a) of the Code by reason of a change in accounting
                  method or otherwise.

                           (g) The Disclosure Schedule sets forth the following
                  information with respect to the Company as of the most recent
                  practicable date (as well as on an estimated pro forma basis
                  as of the Closing giving effect to the consummation of the
                  transactions contemplated hereby): (i) the basis of the
                  Company in its assets; (ii) the amount of any net operating
                  loss, net capital loss, unused investment or other credit,
                  unused foreign tax, or excess charitable contribution
                  allocable to the Company; and (iii) the amount of any deferred
                  gain or loss allocable to the Company arising out of any
                  Deferred Intercompany Transaction (as defined in Treas. Reg.
                  ss.1.1502-13).

                           (h) The unpaid Taxes of the Company (i) did not, as
                  of the date of the latest balance sheet included in the
                  Financial Statements, exceed the reserve for Tax Liability
                  (rather than any reserve for deferred Taxes established to
                  reflect timing differences between book and Tax income) set
                  forth on the face of the latest balance sheet included in the
                  Financial Statements (rather than in any notes thereto) and
                  (ii) do not exceed that reserve as adjusted for the passage of
                  time through the Closing Date in accordance with the past
                  custom and practice of the Company in filing its Tax Returns.

         charge of patent and/or trademark infringement), by or before any
         Governmental Entity, or any Basis in fact therefor known to the Company
         or Seller, against or involving the Company or any of its officers,
         directors or employees (in their capacity as such), assets, business or
         products, whether at law or in equity. None of the actions, suits,
         proceedings, hearings and investigations set forth in the Disclosure
         Schedule could result in any adverse change in the Company. With

         Entity relating to or affecting the operation, conduct or ownership of
         their respective property or business, and no action, suit, proceeding,

                  leased real property:

                                    (i) the Company has not assigned,
                           transferred, conveyed, mortgaged, deeded in trust or

                           and regulations; and

                  and, to the best Knowledge of the Company and Seller, without
                  any default thereunder by any other party thereto. No event
                  has occurred and is continuing which, with due notice or lapse
                  of time or both, would constitute a default or event of
                  default by the Company under any such lease or agreement or,
                  to the best Knowledge of the Company and Seller, by any other
                  party thereto. The Company's possession of such property has
                  not been disturbed and no claim has been asserted in writing
                  against the Company adverse to its rights in such leasehold
                  interests.

                           (e)      All buildings, structures, appurtenances and
                  items of machinery, equipment and other tangible assets used
                  by the Company are in good operating condition and repair,
                  normal wear and tear excepted,

                  all applicable laws, ordinances, codes, rules, regulations and
                  authorizations relating to their construction, use and
                  operation. To the best Knowledge of the Company and Seller,
                  none of the Company's premises or equipment are in need of
                  maintenance or repairs other than ordinary routine maintenance
                  and repairs which are not material, individually or in the
                  aggregate, in nature or cost.

                           (f) The assets and properties owned or leased by the
                  Company are sufficient to operate and conduct the business of
                  the Company in a manner consistent with at least the same
                  standards of quality and reliability as have been achieved as
                  of the date hereof.

                  transaction contemplated hereby, requiring prior notification
                  to any Governmental Entity of the transfer of any permit,

                           (g) There are no underground storage tanks for
                  Hazardous Materials, active or abandoned, at any property now

                  (ii), where applicable, (1) the last two annual reports (5500

                           (c) Each Employee Plan (which, for the purpose of
                  this subsection (c), includes any Employee Plan which, within
                  six years prior to the date hereof, was sponsored, maintained,
                  contributed to or binding upon the Company or an ERISA
                  Affiliate) has been maintained and administered in all
                  respects in accordance with its terms and in compliance with
                  the provisions of applicable law, including, without
                  limitation, applicable disclosure, reporting, funding and
                  fiduciary requirements imposed by ERISA and/or the Code. All
                  contributions, insurance premiums, benefits and other payments
                  required to be made to or under each Employee Plan have been
                  made timely and in accordance with the governing documents and
                  applicable law. With respect to each Employee Plan, (i) no
                  application, proceeding or other matter is pending before the
                  IRS, the Department of Labor, the PBGC or any other
                  governmental agency; (ii) no action, suit, proceeding or claim
                  (other than routine claims for benefits) is pending or
                  threatened; and (iii) to the Knowledge of Seller, no facts
                  exist which could give rise to an action, suit, proceeding or
                  claim which, if asserted, could result in a liability or
                  expense to the Company or the plan assets.

                           (d) With respect to each Employee Plan which is an
                  "employee benefit plan" within the meaning of Section 3(3) of
                  ERISA or which is a "plan" within the meaning of Section
                  4975(e) of the Code, there has occurred no transaction which
                  is prohibited by Section 406 of ERISA or which constitutes a
                  "prohibited transaction" under Section 4975(c) of the Code and
                  with respect to which a prohibited transaction exemption has
                  not been granted and is not currently in effect.

                           (e) The Disclosure Schedule identifies each funded
                  Employee Plan which is an employee pension plan within the
                  meaning of Section 3(2) of ERISA (other than a multiemployer
                  plan within the meaning of Section 3(37) of ERISA). With
                  respect to each such Employee Plan, (i) the Employee Plan is a
                  qualified plan under Section 401(a) or 403(a) of the Code, and
                  its related trust is exempt from Federal income taxation

                  under Section 501(a) of the Code; (ii) a favorable IRS
                  determination letter is currently in effect and, since the
                  date of the last determination letter, the Employee Plan has
                  not been amended or operated in a manner which would adversely
                  affect its qualified status and no event has occurred which
                  has caused or could cause the loss of such status; (iii) there
                  has been no termination or partial termination within the
                  meaning of Section 411(d)(3) of the Code; (iv) with respect to
                  each such Employee Plan which is covered by Section 412 of the
                  Code, there has been no accumulated funding deficiency,
                  whether or not waived, within the meaning of Section 302(a)(2)
                  of ERISA or Section 412 of the Code, and there has been no
                  failure to make a required installment by its due date under
                  Section 412(m) of the Code; and (v) with respect to each such
                  Employee Plan which is covered by Title IV of ERISA, (1) no
                  reportable event within the meaning of Section 4043(b) of
                  ERISA and the regulations thereunder has occurred; (2) no
                  notice of intent to terminate the plan has been provided to
                  participants or filed with the PBGC under Section 4041 of
                  ERISA, nor has the PBGC instituted or threatened to institute
                  any proceeding under Section 4042 of ERISA to terminate the
                  plan; (3) no liability has been incurred under Title IV of
                  ERISA to the PBGC or otherwise (except for the payment of PBGC
                  premiums) and no event or set of conditions exists which would
                  subject the assets of the Company to a lien under Section 412
                  of the Code or under ERISA; and (4) in the case of a defined
                  benefit pension plan (including for this purpose any Employee
                  Plan which is described in Section 4(b)(4) of ERISA), the
                  value of the plan assets exceeds the total present value of
                  the plan's benefit liabilities on a plan termination Basis
                  based upon actuarial assumptions and asset valuation
                  principles applied by the PBGC (or applicable foreign law).
                  Neither the Company nor any ERISA Affiliate has ceased
                  operations at a facility so as to become subject to the
                  provisions of Section 4068(f) of ERISA, withdrawn as a
                  substantial employer so as to become subject to the provisions
                  of Section 4063 of ERISA or ceased making contributions to any
                  Employee Plan which is a pension plan subject to Section
                  4064(a) of ERISA.

                           (f) Each trust which is intended to be exempt from
                  federal income taxation pursuant to Section 501(c)(9) of the
                  Code has been identified as such on the Disclosure Schedule,
                  and each such trust satisfies the requirements of that Section
                  and is covered by a favorable IRS determination letter, and
                  neither the trust nor any related plan has been amended or
                  operated since the date of the most recent determination
                  letter in a manner which would adversely affect such exempt
                  status.

                           (g) No Employee Plan listed on the Disclosure
                  Schedule is a multiemployer plan within the meaning of Section
                  3(37) of ERISA. Neither the Company nor ERISA Affiliate is, or
                  within six years prior to the date hereof was, obligated to
                  contribute or otherwise a party to any such multiemployer
                  plan. Neither the Company nor any ERISA Affiliate has incurred
                  or expects to incur any withdrawal liability under Title IV of
                  ERISA (either as a contributing employer or as part of a
                  controlled



                                       26

                  group which includes a contributing employer) in connection
                  with a complete or partial withdrawal from a multiemployer
                  plan, and no ERISA Affiliate has received notice from any such
                  multiemployer plan that the plan is in reorganization or
                  insolvency pursuant to Sections 4241 or 4245 or ERISA or that
                  the plan is intended to terminate or has terminated under
                  Sections 4041A or 4042 of ERISA.

                           (h) The Company and its ERISA Affiliates have
                  complied in all respects with the provisions of Section
                  4980(B) of the Code with respect to any Employee Plan or
                  benefit arrangement which is a group health plan within the
                  meaning of Section 5001(b)(1) of the Code. Except as may be
                  required under Section 4980(B) of the Code or any similar
                  state law requiring continuous coverage with respect to health
                  plans, the Company does not maintain, contribute to, and is
                  not obligated under any plan, contract, policy or arrangement
                  providing health or death benefits (whether or not insured) to
                  current or former employees or other personnel beyond the
                  termination of their employment or other services. Except as
                  set forth in the Disclosure Schedule, each Employee Plan may
                  be unilaterally terminated and/or amended by the Company at
                  any time.

                           (i) The consummation of the transactions contemplated
                  by this Agreement will not (either alone or in conjunction
                  with another event, such as a termination of employment or
                  other services) entitle any employee or other person to
                  receive severance or other compensation which would not
                  otherwise be payable absent the consummation of the
                  transactions contemplated by this Agreement or cause the
                  acceleration of the time of payment or vesting of any award or
                  entitlement under any Employee Plan.

                           (j) The Disclosure Schedule sets forth a complete and
                  accurate list showing the names, the rate of compensation (and
                  the portions thereof attributable to salary and bonuses,
                  respectively) and location of all current officers of the
                  Company or any ERISA Affiliate and of all employees of or
                  consultants to the Company or any ERISA Affiliate that
                  received, for the year ended December 31, 1996, or are
                  expected to receive, during the year ending December 31, 1997,
                  annual base salary or other compensation in excess of $40,000
                  (or the equivalent thereof in foreign currency). There are no
                  covenants, agreements or restrictions to which the Company or
                  any ERISA Affiliate is a party, including but not limited to
                  employee non-compete agreements, prohibiting, limiting or in
                  any way restricting any officer or employee listed on the
                  Disclosure Schedule from engaging in any types of business
                  activity in any location. To the best Knowledge of the Company
                  and Seller, no officer or employee listed on the Disclosure
                  Schedule, and no group of the Company's or any ERISA
                  Affiliate's employees, has any plans to terminate their
                  employment. There has not been, and neither the Company nor
                  Seller anticipates, any adverse change in relations with
                  employees as a result of the announcement of the transactions
                  contemplated by this Agreement. Neither the Company nor any
                  ERISA Affiliate has instituted any "freeze"



                                       27

<PAGE>   34



                  of, or delayed or deferred the grant of, any cost-of-living or
                  other salary adjustments for any of its employees.

                           (k) The Disclosure Schedule sets forth by number and
                  employment classification the approximate numbers of employees
                  employed by the Company and each ERISA Affiliate as of the
                  date of this Agreement, and, except as set forth therein, none
                  of said employees are subject to union or collective
                  bargaining agreements. There have been no audits of the equal
                  employment opportunity practices of the Company and, to the
                  best Knowledge of the Company and Seller, no Basis for such
                  claim exists. There is no unfair labor practice charge or
                  complaint against the Company pending before the National
                  Labor Relations Board or strike, dispute, slowdown or stoppage
                  pending or threatened against or involving the Company and
                  none has occurred since April 30, 1995. No representation
                  question exists respecting the employees of the Company and no
                  collective bargaining agreement is currently being negotiated
                  by the Company, nor is any grievance procedure or arbitration
                  proceeding pending under any collective bargaining agreement
                  and no claim therefor has been asserted. Neither Seller nor
                  the Company has received notice from any union or employees
                  setting forth demands for representation, elections or for
                  present or future changes in wages, terms of employment or
                  working conditions.

                           (l) The Disclosure Schedule sets forth all
                  outstanding loans and other advances (other than travel
                  advances in the ordinary course of business which do not
                  exceed $5,000 per individual) made by the Company to any of
                  its officers, directors, employees, stockholders or
                  consultants.

                  3.19     Insurance Policies. The Disclosure Schedule contains 
         a correct and complete description of all insurance policies of the
         Company covering the Company and its business, employees, agents and
         assets. Each such policy is in full force and effect and is, to the
         best Knowledge of the Company and Seller, adequate in coverage and
         amount to insure fully against risks to which the Company and its
         employees, businesses, properties and other assets may be exposed in
         the operation of their respective business. All retroactive premium
         adjustments under any worker's compensation policy of the Company have
         been recorded in the Financial Statements in accordance with generally
         accepted accounting principles and are reflected in the Financial
         Statements. All premiums with respect to such insurance policies have
         been paid on a timely basis, and no notice of cancellation or
         termination has been received with respect to any such policy. The
         Company has not failed to give any notice or present any claim
         thereunder in due and timely fashion. There are no pending claims
         against such insurance by the Company as to which the insurers have
         denied coverage or otherwise reserved rights. The Company has not been
         refused any insurance with respect to assets or operations, nor has its
         coverage been limited, by any insurance carrier to which it has applied
         for any such insurance with which it has carried insurance since April
         30, 1995.

                  3.20     Records. The Company has records that accurately and
         validly reflect its transactions and accounting controls sufficient to
         insure that such transactions are (i) in all respects executed in
         accordance with its management's general or specific authorization and
         (ii) recorded in conformity with generally accepted accounting
         principles.

                  3.21     No Illegal or Improper Transactions. Neither the 
         Company nor any of its officers, directors, employees, agents or
         Affiliates has offered, paid or agreed to pay to any person or entity
         (including any governmental official) or solicited, received or agreed
         to receive from any such person or entity, directly or indirectly, any
         money or anything of value for the purpose or with the intent of (i)
         obtaining or maintaining business, (ii) facilitating the purchase or
         sale of any product or service, or (iii) avoiding the imposition of any
         fine or penalty, in any such case in any manner which is in violation
         of any applicable ordinance, regulation or law; and there have been no
         false or fictitious entries made in the books or records of the
         Company.

                  3.22     Brokerage Fees. Neither the Company, Seller nor any 
         of their respective Affiliates has retained any financial advisor,
         broker, agent or finder or paid or agreed to pay any financial advisor,
         broker, agent or finder on account of this Agreement or any transaction
         contemplated hereby or any transaction of like nature that would be
         required to be paid by the Company.

                  3.23     No Product Liabilities; Product Warranties.

                           (a) The Company has not incurred, nor does the
                  Company or Seller know of or have any reason to believe there
                  is any Basis for alleging, any liability, damage, loss, cost
                  or expense as a result of any defect or other deficiency
                  ("Product Liability") with respect to any service rendered by
                  the Company, whether such Product Liability is incurred by
                  reason of any express or implied warranty (including, without
                  limitation, any warranty of merchantability or fitness), any
                  doctrine of common law (tort, contract or other), any
                  statutory provision or otherwise and irrespective of whether
                  such Product Liability is covered by insurance.

                           (b) Seller has furnished Purchaser with the standard
                  forms of warranties or guarantees of the Company's services
                  that are in effect or proposed to be used by it, which forms
                  contain all warranties and guarantees given by the Company to
                  its customers with respect to their services, except for those
                  warranties imposed by law. There are no pending or, to the
                  best Knowledge of the Company and Seller, threatened claims
                  under any warranty or guaranty against the Company. The
                  Disclosure Schedule lists all payments or settlements made in
                  respect of any such warranty or guaranty (including without
                  limitation any returns or allowances) in excess of $10,000
                  since April 30, 1995, indicating the name of each customer,
                  the amount of each payment and a brief description of the
                  facts relating thereto.

<PAGE>   36




                           (a) The Disclosure Schedule lists (i) all suppliers
                  of the Company to which the Company made payments greater than
                  $5,000 during the year ended April 30, 1997, or expect to make
                  payments during the year ending April 30, 1998, and (ii) all
                  customers maintaining charge accounts with the Company or that
                  have purchased trailers from the Company that paid the Company
                  greater than $5,000 during the year ended April 30, 1997 or
                  that the Company expects will pay to the Company during the
                  year ending April 30, 1998.

                           (b) Neither the Company nor Seller has any
                  information which would currently indicate that any of the
                  suppliers of the Company listed on the Disclosure Schedule
                  intend to cease selling to or dealing with the Company nor has
                  any information been brought to its attention which currently
                  leads it to believe any such supplier intends to alter in any
                  respect the amount of such sales or the extent of dealings
                  with the Company or would alter in any respect such sales or
                  dealings in the event of the consummation of the Acquisition.
                  The Company has no information which might reasonably
                  indicate, nor has any information been brought to its
                  attention which might reasonably lead it to believe that, (i)
                  any supplier will not be able to fulfill outstanding or
                  currently anticipated purchase orders placed by the Company
                  which, individually or in the aggregate, exceed $10,000, or
                  (ii) any customer will cancel outstanding or currently
                  anticipated purchase orders placed with the Company which,
                  individually or in the aggregate, exceed $10,000.

                           (c) Neither the Company nor, to the best Knowledge of
                  the Company and Seller, any of their respective officers,
                  directors or Affiliates, nor any relative or spouse (or
                  relative of such spouse) of any such officer, director or
                  Affiliate, nor any entity controlled by one of more of the
                  foregoing:

                               (i) owns, directly or indirectly, any
                           interest in (excepting less than 1% stock holdings
                           for investment purposes in securities of publicly
                           held and traded companies), or is an officer,
                           director, employee or consultant of, any Person which
                           is, or is engaged in business as, a competitor,
                           lessor, lessee, supplier, distributor, sales agent,
                           customer or client of the Company;

                               (ii) owns, directly or indirectly, in whole
                           or in part, any tangible or intangible property that

                               (iii) has any cause of action or other claim
                           whatsoever against, or owes any amount to, the

                           business such as for accrued vacation pay, accrued
                           benefits under employee benefit plans, and similar
                           matters and agreements existing on the date hereof.

                  the Company or in which the Company has any interest and is

                  payment to or interference from any person, all Intellectual
                  Property identified in Schedule 3.25, such Intellectual
                  Property being valid, enforceable and in good standing. The
                  Company does not know, and has received no notice of any claim
                  or infringement or interference or other conflict with the
                  asserted rights of others with respect to any Intellectual
                  Property.

                           (b) The Company owns or has the right to use all
                  inventions (whether or not patentable), all proprietary rights
                  and all business information (including, without limitation,

                  customer/subscriber lists, supplier lists, pricing and cost
                  information and business and marketing plans and proposals)
                  (collectively, "Trade Secrets") necessary for the operation of
                  the business or operations of the Company as presently
                  conducted and as proposed to be conducted, free and clear of
                  all Security Interests and no Trade Secret has been challenged
                  or misappropriated in any way or to the best Knowledge of
                  Seller and the Company, has any proceeding been threatened
                  with respect thereto and none of the subject matter of any
                  such Trade Secret has been misappropriated or is alleged to
                  have been misappropriated from any person.

                           (c) Each item of Intellectual Property owned or used
                  by the Company immediately prior to the Closing hereunder will
                  be owned or available for use by the Company on identical
                  terms and conditions immediately subsequent to the Closing
                  hereunder. The Company has taken all necessary and desirable
                  action to maintain and protect each item of Intellectual
                  Property that it owns or uses.

                  3.26     Licenses. The Company has all licenses, permits and 
         other governmental certificates, authorizations and approvals required
         by every Federal, state, local and foreign Governmental Entity for the
         conduct of its business and the use of its properties as presently
         conducted or used including, without limitation, all licenses required
         under Environmental Laws and any Federal, state, local or foreign law
         relating to public health and safety, or employee health and safety
         (collectively, "Company Licenses"). The Disclosure Schedule contains a
         true and complete list of the Company Licenses, exclusive of any
         Company Licenses with respect to state or local sales, use or other
         Taxes. All of the Company Licenses are in full force and effect and no
         action or claim is pending nor, to the best Knowledge of the Company
         and Seller, is threatened to revoke or terminate any Company License or
         declare any Company License invalid in any respect. The Company has
         taken all necessary action to maintain such Company Licenses. The

         list of all Federal, state, local and foreign governmental or judicial
         consents, orders, decrees and other compliance agreements relating to
         the Company or any of its assets or business under which the Company is
         operating or bound.

                  3.27     Restrictive Documents and Territorial Restrictions. 
         The Company is not subject to, or a party to, any charter, by-law,
         mortgage, Security Interest, lease, license, permit, agreement,
         contract, instrument, law, rule, ordinance, regulation, order, judgment
         or decree, or any other restriction of any kind or character, which
         adversely affects the business, prospects, operations or condition
         (financial or otherwise) of the Company or any of its assets or
         property, or which would prevent consummation of the transactions
         contemplated hereby, or the continued operation of the Company's
         business after the date hereof on substantially the same basis as
         heretofore operated or which would restrict the ability of the Company
         to acquire any property or conduct business in any area.

                  3.28     No Misleading Statements. This Agreement, the 
         information and schedules referred to herein and the information that
         has been furnished to Purchaser in connection with the transactions
         contemplated hereby do not include any untrue statement of a material
         fact and do not omit to state any material fact necessary to make the
         statements contained herein or therein, in light of the circumstances
         under which they were made, not misleading. There is no fact known to
         the Company or Seller which adversely affects or in the future may (so
         far as the Company or Seller can now reasonably foresee) adversely
         affect the business, condition (financial or otherwise), property or
         assets of the Company which has not been set forth herein.

         4.       Additional Representations and Warranties Relating to Seller.

         Seller represents and warrants to Purchaser and Rush that the
statements contained in this Article 4 are correct and complete as of the date
of this Agreement and will be correct and complete as of the Closing Date (as
though made then and as though the Closing Date were substituted for the date of
this Agreement throughout this Article 4), except as set forth in the Seller
Disclosure Schedule attached hereto. Nothing in the Seller Disclosure Schedule
shall be deemed adequate to disclose an exception to a representation or
warranty made herein, however, unless the Seller Disclosure Schedule identifies
the exception with reasonable particularity and describes the relevant facts in
reasonable detail. Without limiting the generality of the foregoing, the mere
listing (or inclusion of a copy) of a document or other item shall not be deemed
adequate to disclose an exception to a representation or warranty made herein
(unless the representation or warranty has to do with the existence of the
document or other item itself). The Seller Disclosure Schedule will be arranged
in paragraphs corresponding to the lettered and numbered paragraphs contained in
this Article 4.

                  4.1      Due Authorization. Seller has full power and 
         authority to execute and deliver this Agreement and to perform her
         obligations hereunder and thereunder. Seller has duly executed this
         Agreement, and this Agreement is, and each other agreement contemplated
         hereby to which she will be a party will be, upon execution and
         delivery thereof by her, her legal, valid and binding



                                       32

<PAGE>   39



         obligation, enforceable against her in accordance with its terms
         (except as the enforceability thereof may be limited by any applicable
         bankruptcy, insolvency or other laws affecting creditors' rights
         generally or by general principles of equity, regardless of whether
         such enforceability is considered in equity or at law).

                  4.2      No Conflict. Neither Seller's execution and delivery 
         of this Agreement nor the consummation of the transactions contemplated
         hereby or thereby by her will (i) conflict with, result in a breach or
         violation of or constitute (or with notice or lapse of time or both
         constitute) a default under any law, statute, regulation, order,
         judgment or decree or any instrument, contract or other agreement to
         which she is a party or by which she (or any of her assets or
         properties) is bound; or (ii) require her to obtain any authorization,
         consent, approval or waiver from, to give notification to, or to make
         any filing with, any Governmental Entity or Regulatory Authority, or to
         obtain the approval or consent of any other Person.

                  4.3      Stock. Seller has full right, power and authority to 
         sell, transfer, assign and deliver the Company Stock being sold by her
         hereunder. Immediately prior to the delivery of the shares of Company
         Stock being sold by her, she was the sole registered and beneficial
         owner of such shares of Company Stock and had good and valid title to
         such shares of Company Stock, free and clear of all Security Interests,
         rights or claims of others, restrictions on transfer or other
         encumbrances (other than restrictions on transfer imposed by the
         Securities Act and state securities laws) and, upon consummation of the
         transactions contemplated hereby, assuming that Purchaser purchases
         such shares of Company Stock in good faith without notice of any
         adverse claims as defined in Section 8.302 of the Uniform Commercial
         Code as in effect in the State of Texas on the date hereof, Purchaser
         will have acquired all the rights of Seller in such shares of Company
         Stock free of any adverse claim, any lien in favor of the Company or
         restrictions on transfer (other than restrictions on transfer imposed
         by the Securities Act and state securities laws). There are no
         outstanding options, warrants, convertible securities, calls, rights,
         commitments, preemptive rights or agreements or instruments or
         understandings of any character to which Seller is a party or by which
         Seller is bound, obligating Seller to issue, deliver or sell, or cause
         to be issued, delivered or sold, contingently or otherwise, any shares
         of Company Stock owned by Seller or any securities or obligations
         convertible into or exchangeable for such shares or to grant, extend or
         enter into any such option, warrant, convertible security, call, right,
         commitment, preemptive right or agreement. Seller is not a party to any
         voting trust agreements or other contracts, agreements, arrangements,
         commitments, plans or understandings restricting or otherwise relating
         to voting, dividend or other rights with respect to the Company Stock
         owned by her. The Company Stock is the separate property of Seller and
         neither Bobby Hawkins nor any other Persons have any community property
         or other interest in such Company Stock.

                  4.4      Brokers. Seller has not paid or become obligated to 
         pay any fee or commission to any broker, finder, investment banker or
         other intermediary in connection with the transactions contemplated by
         this Agreement.

         5.       Representations and Warranties of Purchaser.

         Purchaser represents and warrants to Seller that the statements
contained in this Article 5 are correct and complete as of the date of this
Agreement and will be correct and complete as of the Closing Date (as though
made then and as though the Closing Date were substituted for the date of this
Agreement throughout this Article 5), except as set forth in Purchaser
Disclosure Schedule attached hereto. Nothing in Purchaser Disclosure Schedule
shall be deemed adequate to disclose an exception to a representation or
warranty made herein, however, unless the Purchaser Disclosure Schedule
identifies the exception with reasonable particularity and describes the
relevant facts in reasonable detail. Without limiting the generality of the
foregoing, the mere listing (or inclusion of a copy) of a document or other item
shall not be deemed adequate to disclose an exception to a representation or
warranty made herein (unless the representation or warranty has to do with the
existence of the document or other item itself). The Purchaser Disclosure
Schedule will be arranged in paragraphs corresponding to the lettered and
numbered paragraphs contained in this Article 5.

                  5.1      Organization. Purchaser is a corporation duly 
         organized, validly existing and in good standing under the laws of the
         State of Delaware, with full corporate power and authority to own or
         lease its properties and carry on its business as presently conducted.
         Purchaser is licensed or qualified to transact business and is in good
         standing as a foreign corporation in each jurisdiction where the
         character of its business or the nature of its properties makes such
         qualification or licensing necessary.

                  5.2      Due Authorization. Purchaser has all requisite
         corporate power and authority to execute and deliver this Agreement and
         to perform fully its obligations hereunder and thereunder and to
         consummate the transactions contemplated hereby and thereby. The
         execution and delivery of this Agreement by Purchaser, the performance
         by Purchaser of its obligations hereunder and thereunder, and the
         transactions contemplated hereby and thereby have been duly and validly
         authorized by all necessary corporate action on the part of Purchaser.
         This Agreement has been duly executed by Purchaser, and this Agreement
         is a legal, valid and binding obligation of Purchaser enforceable
         against Purchaser in accordance with its terms (except as the
         enforceability thereof may be limited by any applicable bankruptcy,
         insolvency or other laws affecting creditors' rights generally or by
         general principles of equity, regardless of whether such enforceability
         is considered in equity or at law).

                  5.3      No Conflict. Neither the execution and delivery of
         this Agreement by Purchaser nor the consummation of the transactions
         contemplated hereby or thereby by Purchaser will (i) conflict with,
         result in a breach or violation of or constitute (or with notice or
         lapse of time or both constitute) a default under, (A) the certificate
         of incorporation or by-laws of Purchaser, or (B) any law, statute,
         regulation, order, judgment or decree or any instrument, contract or
         other agreement to which Purchaser is a party or by which it (or any of
         its properties or assets) is subject or bound; (ii) result in the
         creation of, or give any party the right to create, any Security
         Interest or other adverse interest upon any property or asset of
         Purchaser; (iii) terminate or modify, or give any third party the right



                                       34

<PAGE>   41



         to terminate or modify, the provisions or terms of any agreement or
         commitment to which Purchaser is a party or by which it (or any of its
         properties or assets) is subject or bound; or (iv) require Purchaser to
         obtain any authorization, consent, approval or waiver from, to give
         notification to, or to make any filing (other than filing to qualify as
         a foreign corporation where necessary) with, any Governmental Entity or
         Regulatory Authority, or to obtain the approval or consent of any other
         Person.

                  5.4      Brokers. Neither Purchaser nor any of its Affiliates 
         has paid or become obligated to pay any fee or commission to any
         broker, finder, investment banker or other intermediary in connection
         with the transactions contemplated by this Agreement.

                  5.5      Securities Act. Purchaser represents and warrants to
         Seller that the Company Stock is being acquired solely for its own
         account for investment and not with a view to, or for offer or resale
         in connection with, a distribution thereof within the meaning of the
         Securities Act.

         6.       Pre-closing Covenants.

         The Parties agree as follows, except as otherwise described on the
Disclosure Schedule, with respect to the period between the execution of this
Agreement and the Closing:

                  6.1      General. Each of the Parties will use her or its
         reasonable best efforts to take all action and to do all things
         necessary, proper, or advisable in order to consummate and make
         effective the transactions contemplated by this Agreement (including
         satisfaction, but not waiver, of the closing conditions set forth in
         Article 8 below).

                  6.2      Notices and Consents. Each of the Parties, as 
         promptly as practicable, (i) will make, or cause to be made, all
         filings and submissions required under laws, rules and regulations
         applicable to it, or to its Subsidiaries and Affiliates, as may be
         required for it to consummate the transactions contemplated hereby;
         (ii) will use their respective reasonable efforts to obtain, or cause
         to be obtained, all authorizations, approvals, consents and waivers
         from all Persons, Governmental Entities and Regulatory Authorities
         necessary to be obtained by each of them, or any of their respective
         Subsidiaries or Affiliates, in order for each of them, respectively, so
         to consummate such transactions; and (iii) will use their respective
         best efforts to take, or cause to be taken, all other actions
         necessary, proper or advisable in order for each of them to fulfill
         their respective obligations hereunder.

                  6.3      Operation of Business. The Company will not, and 
         Seller will not cause or permit the Company to engage in any practice,
         take any action, or enter into any transaction outside the Ordinary
         Course of Business. Without limiting the generality of the foregoing,
         the Company will not, and Seller will not cause or permit the Company
         to, (i) declare, set aside, or pay any dividend or make any
         distribution with respect to its capital stock, except as provided in
         Section



                                       35

         3.10(v), or redeem, purchase or otherwise acquire any of its capital
         stock, (ii) take any action or omit to take any action which act or
         omission would result in the inaccuracy of any of its representations
         and warranties set forth herein if such representations or warranties
         were to be made immediately after the occurrence of such act or
         omission, or (iii) otherwise engage in any practice, take any action or
         enter into any transaction of the sort described in Section 3.10 above.

                  6.4      Preservation of Business. The Company and Seller
         will, and Seller will cause the Company to, (a) keep its business and
         properties substantially intact, including its present operations,
         physical facilities, working conditions and relationships with lessors,
         licensors, suppliers, customers and employees and (b) comply in all
         respects with all laws, ordinances, rules, regulations and orders
         applicable to its business.

                  6.5      Full Access. The Company and Seller will, and Seller 
         will cause the Company to, permit representatives of Purchaser and its
         financing parties, upon not less than 24 hours notice to Seller, to
         have full access at all reasonable times, and in a manner so as not to
         interfere with the normal business operations of the Company to all
         premises, properties, personnel, books, records (including Tax records
         and the workpapers of the independent accountants for the Company,
         contracts and documents of or pertaining to the Company).

                  6.6      Notice of Developments. Each Party will give prompt
         written notice to the others of any adverse development causing a
         breach of any of her or its own representations and warranties in
         Articles 3, 4 or 5 above. No disclosure by any Party pursuant to this
         Section 6.6, however, shall be deemed to amend or supplement the
         Disclosure Schedule, the Seller Disclosure Schedule or the Purchaser
         Disclosure Schedule or to prevent or cure any misrepresentation, breach
         of warranty or breach of covenant.

                  6.7      Updated Financial Statements. As soon as available 
         and in any event within 30 days after the end of each month prior to
         the Closing Date, commencing with January 31, 1998, Seller shall
         deliver to Purchaser a consolidated balance sheet and related statement
         of operations and cash flows of the Company. All such financial
         statements shall be covered by and conform to the representations and
         warranties set forth in Section 3.7 hereof and shall be included in the
         term "Financial Statements" for purposes of this Agreement.

                  6.8      Exclusivity.

                           (a) Seller will not, and will not cause or permit any
                  of the Company to, (i) solicit, initiate or encourage the
                  submission of any proposal or offer from any Person relating
                  to a Business Combination or (ii) participate in any
                  discussions or negotiations regarding, furnish any information
                  with respect to, assist or participate in, or facilitate in
                  any other manner any effort or attempt by any Person to do or
                  seek a Business Combination. Seller will notify Purchaser
                  immediately if any



                                       36

<PAGE>   43



                  Person makes any proposal, offer, inquiry, or contact with
                  respect to any of the foregoing.

                           (b) The Parties hereto recognize and acknowledge that
                  a breach by Seller of this Section 6.8 will cause irreparable
                  and material loss and damage to Purchaser as to which it will
                  not have an adequate remedy at law or in damages. Accordingly,
                  each Party acknowledges and agrees that the issuance of an
                  injunction or other equitable remedy is an appropriate remedy
                  for any such breach. In addition, in the event of any breach
                  of the foregoing which results in Business Combination with a
                  Person other than Purchaser within 12 months of the date of
                  such breach, Seller shall promptly reimburse Purchaser for the
                  reasonable expenses incurred by Purchaser in connection with
                  the transactions contemplated by this Agreement.

                  6.9      Environmental Inspections and Assessments. Purchaser
         shall have the right to inspect the records and the operations of the
         Company with respect to environmental matters, and shall have the right
         to require the Company to conduct Phase I assessments, as it deems
         appropriate. The Company shall pay the cost of such Phase I
         assessments. The representations, warranties, indemnities and other
         undertakings set forth herein shall not be affected by any such
         inspection or assessment or lack thereof, or the results of any such
         inspection or assessment.

                  6.10     Schedules. From time to time prior to the Closing, 
         Seller and the Company will promptly supplement or amend the Disclosure
         Schedule with respect to any matter hereafter arising which, if
         existing or occurring at the date of this Agreement, would have been
         required to be set forth or described in such Disclosure Schedule. No
         supplement or amendment of the Disclosure Schedule made pursuant to
         this Section shall be deemed to cure any breach of, affect or otherwise
         diminish any representation or warranty made in this Agreement unless
         Purchaser specifically agrees thereto in writing.

                  6.11     Inventory Audit. Within thirty (30) days prior to
         Closing, Seller and Purchaser shall mutually agree on an appraiser
         knowledgeable in the farm and ranch business, and shall cause such
         appraiser to conduct an audit (in accordance with generally accepted
         accounting principles, consistently applied) of the inventory of the
         Company's assets as of the Closing Date. Each of the Company and
         Purchaser shall pay one-half of the cost of conducting such audit.

                  6.12     Company Information. The Company and Seller shall
         provide to Purchaser all financial information of the Company in the
         format required in connection with the filing of financial information
         of the Company with Purchaser's Current Report on Form 8-K under the
         Exchange Act required in connection with Purchaser's acquisition of the
         Business. Once such information has been provided to Purchaser, the
         expense of preparation of such Form 8-K shall be borne entirely by
         Purchaser.

         7.       Post-closing Covenants.

         The Parties agree as follows with respect to the period following the
Closing:

                  7.1      General. In case at any time after the Closing any 
         further action is necessary or desirable to carry out the purposes of
         this Agreement, each of the Parties will take such further action
         (including the execution and delivery of such further instruments and
         documents) as any other Party reasonably may request, all at the sole
         cost and expense of the requesting Party (unless the requesting Party
         is entitled to indemnification therefor under Article 9 below). Seller
         acknowledges and agrees that from and after the Closing Purchaser will
         be entitled to possession of all documents, books, records (including
         Tax records), agreements, and financial data of any sort relating to
         the Company. Purchaser will afford to Seller reasonable access to, and
         copies of, the records of the Company transferred to Purchaser at the
         Closing during normal business hours after the Closing.

                  7.2      Litigation Support. In the event and for so long as 
         any Party actively is contesting or defending against any action, suit,
         proceeding, hearing, investigation, charge, complaint, claim or demand
         in connection with (i) any transaction contemplated under this
         Agreement or (ii) any fact, situation, circumstance, status, condition,
         activity, practice, plan, occurrence, event, incident, action, failure
         to act or transaction on or prior to the Closing Date involving the
         Company, each of the other Parties will cooperate with her or it and
         her or its counsel in the contest or defense, make available their
         personnel, and provide such testimony and access to their books and
         records as shall be necessary in connection with the contest or
         defense, all at the sole cost and expense of the contesting or
         defending Party (unless the contesting or defending Party is entitled
         to indemnification therefor under Article 9 below).

                  7.3      Transition. Seller will not take any action that is
         designed or intended to have the effect of discouraging any lessor,
         licensor, customer, supplier or other business associate of any of the
         Company from maintaining the same business relationships with the
         Company after the Closing as it maintained with the Company prior to
         the Closing. Seller will refer all customer inquiries relating to the
         businesses of the Company to Purchaser from and after the Closing.

                  7.4      Confidentiality. Seller recognizes and acknowledges
         that she has and will have access to certain Confidential Information
         of the Company that, after the consummation of the transactions
         contemplated hereby, will be valuable, special and unique property of
         Purchaser. Seller agrees that she will, and will cause her Affiliates
         and representatives, to keep confidential and not disclose to any other
         Person or use for her own benefit or for the benefit of any other
         Person, and she will use her 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 (i) is then generally known to the public; (ii)
         become or becomes generally known to the



                                       38

<PAGE>   45



         public through no fault of Seller, her Affiliates or representatives;
         and (iii) 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 of any of the provisions contained in this
         Section 7.4 of this Agreement, Seller acknowledges that Purchaser and
         Rush 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, Purchaser and Rush 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 Purchaser and Rush may have
         under this Agreement, at law or in equity, including, without
         limitation, the right to sue for damages.

                  7.5      Tax Matters. The following provisions shall govern 
         the allocation of responsibility as between Purchaser and Seller for
         certain tax matters following the Closing Date:

                           (a) Tax Periods Ending on or Before the Closing Date.
                  Seller shall prepare or cause to be prepared and file or cause
                  to be filed all Tax Returns for the Company for all periods
                  ending on or prior to the Closing Date which are filed after
                  the Closing Date. Seller shall permit Purchaser to review and
                  comment on each such Tax Return described in the preceding
                  sentence prior to filing. Seller shall reimburse Purchaser for
                  Taxes of the Company with respect to such periods within
                  fifteen (15) days after payment by Purchaser or the Company of
                  such Taxes to the extent such Taxes are not reflected in the
                  reserve for Tax Liability (rather than any reserve for
                  deferred Taxes established to reflect timing differences
                  between book and Tax income) shown on the face of the Closing
                  Date Balance Sheet.

                           (b) Tax Periods Beginning Before and Ending After the
                  Closing Date. Purchaser shall prepare or cause to be prepared
                  and file or cause to be filed any Tax Returns of the Company
                  for Tax periods which begin before the Closing Date and end
                  after the Closing Date. Seller shall pay to Purchaser within
                  fifteen (15) days after the date on which Taxes are paid with
                  respect to such periods an amount equal to the portion of such
                  Taxes which relates to the portion of such Taxable period
                  ending on the Closing Date to the extent such Taxes are not
                  reflected in the reserve for Tax Liability (rather than any
                  reserve for deferred Taxes established to reflect timing
                  differences between book and Tax income) shown on the face of
                  the Closing Date Balance Sheet. For purposes of this clause
                  (b), in the case of any Taxes that are imposed on a periodic
                  basis and are payable for a Taxable period that includes (but
                  does not end on) the Closing Date, the portion of such Tax
                  which relates to the portion of such Taxable period ending on
                  the Closing Date shall (x) in the case of any Taxes other than
                  Taxes based upon or related to income or receipts, be deemed
                  to be the amount of such Tax for the entire Taxable period



                                       39

<PAGE>   46



                  multiplied by a fraction, the numerator of which is the number
                  of days in the Taxable period ending on the Closing Date, and
                  the denominator of which is the number of days in the entire
                  Taxable period, and (y) in the case of any Tax based upon or
                  related to income or receipts be deemed equal to the amount
                  which would be payable if the relevant Taxable period ended on
                  the Closing Date. Any credits relating to a Taxable period
                  that begins before and ends after the Closing Date shall be
                  taken into account as though the relevant Taxable period ended
                  on the Closing Date. All determinations necessary to give
                  effect to the foregoing allocations shall be made in a manner
                  consistent with prior practice of the Company.

                           (c)      Cooperation on Tax Matters.

                                    (i) Purchaser, the Company and Seller shall
                  cooperate fully, as and to the extent reasonably requested by
                  the other party, in connection with the filing of Tax Returns
                  pursuant to this Section and any audit, litigation or other
                  proceeding with respect to Taxes. Such cooperation shall
                  include the retention and (upon the other party's request) the
                  provision of records and information which are reasonably
                  relevant to any such audit, litigation or other proceeding and
                  making employees available on a mutually convenient basis to
                  provide additional information and explanation of any material
                  provided hereunder. The Company and Seller agree (A) to retain
                  all books and records with respect to Tax matters pertinent to
                  the Company relating to any Taxable period beginning before
                  the Closing Date until the expiration of the Taxable period
                  beginning before the Closing Date until the expiration of the
                  statute of limitations (and, to the extent notified by
                  Purchaser or Seller, any extensions thereof) of the respective
                  Taxable periods, and to abide by all record retention
                  agreements entered into with any taxing authority, and (B) to
                  give the other party reasonable written notice prior to
                  transferring, destroying or discarding any such books and
                  records and, if the other party so requests, the Company or
                  Seller, as the case may be, shall allow the other party to
                  take possession of such books and records.

                                    (ii) Purchaser and Seller further agree,
                  upon request, to use their reasonable best efforts to obtain
                  any certificate or other document from any Governmental Entity
                  or any other Person as may be necessary to mitigate, reduce or
                  eliminate any Tax that could be imposed (including, but not
                  limited to, with respect to the transactions contemplated
                  hereby).

                                    (iii) Purchaser and Seller further agree,
                  upon request, to provide the other party with all information
                  that either party may be required to report pursuant to
                  Section 6043 of the Code and all Treasury Department
                  Regulations promulgated thereunder.

                           (d)      Certain Taxes. All transfer, documentary, 
                  sales, use, stamp, registration and other such Taxes and fees
                  (including any penalties and



                                       40

<PAGE>   47



                  interest) incurred in connection with this Agreement, shall be
                  paid by Seller when due, and Seller will, at its expense, file
                  all necessary Tax Returns and other documentation with respect
                  to all such transfer, documentary, sales, use, stamp,
                  registration and other Taxes and fees.


                           (e)      Name. Seller will not use any name or
                  trademark containing the phrase "D&D" or any derivative
                  thereof.

         8.       Conditions to Obligation to Close.

                  8.1      Conditions to Obligation of Purchaser. The obligation
         of Purchaser to consummate the transactions to be performed by it in
         connection with the Closing is subject to satisfaction of the following
         conditions:

                           (a) all representations and warranties of the Company
                  and Seller contained in this Agreement (including the
                  Schedules hereto), and all written information delivered to
                  Purchaser by the Company and Seller on or prior to the Closing

                  Purchaser, the Company or Rush may suffer through and after
                  the date of the claim for indemnification (including any

                  suffer after the end of any applicable survival period)
                  resulting from, arising out of, relating to, in the nature of

                  Consequences resulting from, arising out of, relating to, in
                  the nature of or caused by the breach (or alleged breach) of

                  (or alleged breaches) in excess of $25,000, and then for all
                  such Adverse Consequences, and provided further that Seller's
                  maximum liability hereunder shall not exceed the Purchase
                  Price. Notwithstanding anything herein to the contrary, the

                  Adverse Consequences resulting from breaches of the

                  (or for any Tax year beginning before and ending after the
                  Closing Date to the extent allocable (determined in a manner
                  consistent with Section 7.5) to the portion of such period
                  beginning before and ending on the Closing Date), to the
                  extent such Taxes are not reflected in the reserve for Tax
                  Liability (rather than any reserve for deferred Taxes
                  established to reflect timing differences between book and Tax
                  income) shown on the face of the Closing Date Balance Sheet,
                  (x) for the unpaid Taxes of any Person (other than the

                  provision of state, local or foreign law), as a transferee or
                  successor, by contract or otherwise, (y) for the legal
                  proceedings listed on the Disclosure Schedule or any legal
                  proceedings (whether or not disclosed on the Disclosure
                  Schedule) commenced after the Closing Date but in which the

<PAGE>   52



                  principal event(s) giving rise thereto occurred prior to the
                  Closing, or (z) for any Environmental Liabilities.

                  9.3      Indemnification Provisions for Benefit of the Seller.
         In the event the Purchaser breaches (or in the event any third party
         alleges facts that, if true, would mean the Purchaser has breached) any
         of its representations, warranties and covenants contained herein, and,
         if there is an applicable survival period pursuant to Section 9.1
         above, provided that the Seller makes a written claim for
         indemnification against the Purchaser within such survival period, then
         the Purchaser agrees to indemnify the Seller from and against the
         entirety of any Adverse Consequences the Seller may suffer through and
         after the date of the claim for indemnification (including any Adverse
         Consequences the Seller may suffer after the end of any applicable
         survival period) resulting from, arising out of, relating to, in the
         nature of or caused by the breach (or alleged breach); provided,
         however, that Purchaser shall not have any obligation to indemnify the
         Seller from and against any Adverse Consequences resulting from,
         arising out of, relating to, in the nature of or caused by the breach
         (or alleged breach) of any representation or warranty of the Purchaser
         until the Seller has, in the aggregate, suffered Adverse Consequences
         by reason of all such breaches (or alleged breaches) in excess of
         $25,000, and then for all such Adverse Consequences up to and including
         the $25,000, and provided further that Purchaser's maximum liability
         hereunder shall not exceed the Purchase Price.

                  9.4      Matters Involving Third Parties.

                           (a) If any third party shall notify any Party (the
                  "INDEMNIFIED PARTY") with respect to any matter (a "THIRD
                  PARTY CLAIM") which may give rise to a claim for
                  indemnification against any other Party (the "INDEMNIFYING
                  PARTY") under this Article 9, then the Indemnified Party shall
                  promptly notify each Indemnifying Party thereof in writing;
                  provided, however, that no delay on the part of the
                  Indemnified Party in notifying any Indemnifying Party shall
                  relieve the Indemnifying Party from any obligation hereunder
                  unless (and then solely to the extent) the Indemnifying Party
                  thereby is prejudiced.

                           (b) Any Indemnifying Party will have the right to
                  defend the Indemnified Party against the Third Party Claim
                  with counsel of its choice reasonably satisfactory to the
                  Indemnified Party so long as (i) the Indemnifying Party
                  notifies the Indemnified Party in writing within fifteen (15)
                  days after the Indemnified Party has given notice of the Third
                  Party Claim that the Indemnifying Party will indemnify the
                  Indemnified Party from and against the entirety of any Adverse
                  Consequences the Indemnified Party may suffer resulting from,
                  arising out of, relating to, in the nature of or caused by the
                  Third Party Claim, (ii) the Indemnifying Party provides the
                  Indemnified Party with the evidence reasonably acceptable to
                  the Indemnified Party that the Indemnifying Party will have
                  the financial resources to defend against the Third Party
                  Claim and fulfill its indemnification obligations hereunder,
                  (iii) the Third Party Claim involves only money damages and
                  does not seek an injunction or other



                                       46

                  equitable relief, (iv) settlement of, or an adverse judgment
                  with respect to, the Third Party Claim is not, in the good
                  faith judgment of the Indemnified Party, likely to establish a
                  precedential custom or practice adverse to the continuing
                  business interests of the Indemnified Party, and (v) the
                  Indemnifying Party conducts the defense of the Third Party
                  Claim actively and diligently.

                           (c) So long as the Indemnifying Party is conducting
                  the defense of the Third Party Claim in accordance with
                  Section 9.4(b) above, (i) the Indemnified Party may retain
                  separate co-counsel at its sole cost and expense and
                  participate in the defense of the Third Party Claim, (ii) the
                  Indemnified Party will not consent to the entry of any
                  judgment or enter into any settlement with respect to the
                  Third Party Claim without the Prior written consent of the
                  Indemnifying Party (not to be withheld, delayed or conditioned
                  unreasonably), and (iii) the Indemnifying Party will not
                  consent to the entry of any judgment or enter into any
                  settlement with respect to the Third Party Claim without the
                  prior written consent of the Indemnified Party (not to be
                  withheld, delayed or conditioned unreasonably).

                           (d) In the event any of the conditions in Section
                  9.4(b) above is or becomes unsatisfied, however, (i) the
                  Indemnified Party may defend against, and consent to the entry
                  of any judgment or enter into any settlement with respect to,
                  the Third Party Claim in any manner it reasonably may deem
                  appropriate (and the Indemnified Party need not consult with,
                  or obtain any consent from, any Indemnifying Party in
                  connection therewith), (ii) the Indemnifying Parties will
                  reimburse the Indemnified Party promptly and periodically for
                  the costs of defending against the Third Party Claim
                  (including reasonable attorneys' fees and expenses), and (iii)
                  the Indemnifying Parties will remain responsible for any
                  Adverse Consequences the Indemnified Party may suffer
                  resulting from, arising out of, relating to, in the nature of,
                  or caused by the Third Party Claim to the fullest extent
                  provided in this Article 9.

                  9.5      Determination of Adverse Consequences. All 
         indemnification payments under this Article 9 shall be deemed
         adjustments to the Purchase Price.

                  9.6      Other Indemnification Provisions. The foregoing
         indemnification provisions are in addition to, and not in derogation
         of, any statutory, equitable or common law remedy any Party may have
         for breach of representation, warranty or covenant. Seller hereby
         agrees that she will not make any claim for indemnification against the
         Company by reason of the fact that she was a stockholder, director,
         officer, employee or agent of any such entity or was serving at the
         request of any such entity as a partner, trustee, director, officer,
         employee or agent of another entity (whether such claim is for
         judgments, damages, penalties, fines, costs, amounts paid in
         settlement, losses, expenses or otherwise and whether such claim is
         pursuant to any statute, charter document, bylaw, agreement or
         otherwise) with respect to any action, suit, proceeding, complaint,



                                       47

<PAGE>   54



         claim or demand brought by the Purchaser against such Seller (whether
         such action, suit, proceeding, complaint, claim, or demand is pursuant
         to this Agreement, applicable law or otherwise).

                  9.7      INDEMNIFICATION IF NEGLIGENCE OF INDEMNITEE. THE
         INDEMNIFICATION PROVIDED IN THIS ARTICLE 9 SHALL BE APPLICABLE WHETHER
         OR NOT THE SOLE OR CONCURRENT NEGLIGENCE OR GROSS NEGLIGENCE OF THE
         PARTY SEEKING INDEMNIFICATION, OR THE SOLE OR CONCURRENT STRICT
         LIABILITY IMPOSED ON THE PARTY SEEKING INDEMNIFICATION, OR THE SOLE OR
         CONCURRENT LIABILITY IMPOSED VICARIOUSLY ON THE PARTY SEEKING
         INDEMNIFICATION, IS ALLEGED OR PROVEN.

                  9.8      Releases.

                           (a) As of the Closing, Seller does hereby for such
                  Seller and such Seller's Affiliates, heirs, executors,
                  administrators and legal representatives remise, release,
                  acquit and forever discharge the Company and its Affiliates,
                  officers, directors, controlling Persons or entities,
                  employees, attorneys and successors and assigns (collectively,
                  the "Company Released Parties") of and from any and all
                  claims, demands, liabilities, responsibilities, disputes,
                  causes of action and obligations of every nature whatsoever,
                  liquidated or unliquidated, known or unknown, matured or
                  unmatured, fixed or contingent, which such Seller and such
                  Seller's Affiliates now have, own or hold or have at any time
                  previously had, owned or held against the Company Released
                  Parties, including without limitation all liabilities created
                  as a result of the sole or contributory negligence, gross
                  negligence and willful acts of any Company Released Party,
                  existing as of the Closing or relating to any matter that
                  occurred on or prior to the Closing; provided, however, that
                  any claims, liabilities, debts or causes of action that may
                  arise in connection with the failure of any of the parties
                  hereto to perform any of their obligations hereunder or under
                  any other agreement relating to the transactions contemplated
                  hereby or from any breaches by any of them of any
                  representations or warranties herein or in connection with any
                  of such other agreements shall not be released or discharged
                  pursuant to this Agreement. Seller represents and warrants
                  that such Seller has not previously assigned or transferred,
                  or purported to assign or transfer, to any Person or entity
                  whatsoever all or any part of the claims, demands,
                  liabilities, responsibilities, disputes, causes of action or
                  obligations released in this Section 9.8(a). Seller covenants
                  and agrees that such Seller will not assign or transfer to any
                  Person or entity whatsoever all or any part of the claims,
                  demands, liabilities, responsibilities, disputes, causes of
                  action or obligations released in this Section 9.8(a). Each of
                  Seller and Purchaser represent and warrant to the other that
                  they have been represented or advised by legal counsel and
                  other professional advisors in connection with the negotiation
                  and delivery of this Agreement.

                           (b) As of the Closing, the Company does hereby for
                  such Company remise, release, acquit and forever discharge
                  Seller and Seller's Affiliates, heirs, executors,
                  administrators and legal representatives (collectively, the
                  "Seller Released Parties") of and from any and all claims,
                  demands, liabilities, responsibilities, disputes, causes of
                  action and obligations of every nature whatsoever, liquidated
                  or unliquidated, known or unknown, matured or unmatured, fixed
                  or contingent, which such Company now have, own or hold or
                  have at any time previously had, owned or held against the
                  Seller Released Parties, including without limitation all
                  liabilities created as a result of the sole or contributory
                  negligence, gross negligence and willful acts of any Seller
                  Released Party, existing as of the Closing or relating to any
                  matter that occurred on or prior to the Closing; provided,
                  however, that any claims, liabilities, debts or causes of
                  action that may arise in connection with the failure of any of
                  the parties hereto to perform any of their obligations
                  hereunder or under any other agreement relating to the
                  transactions contemplated hereby or from any breaches by any
                  of them of any representations or warranties herein or in
                  connection with any of such other agreements shall not be
                  released or discharged pursuant to this Agreement. The Company
                  covenants and agrees that after the Closing Date the Company
                  will not assign or transfer to any Person or entity whatsoever
                  all or any part of the claims, demands, liabilities,
                  responsibilities, disputes, causes of action or obligations
                  released in this Section 9.8(b). Seller represents and
                  warrants that neither Seller nor Seller Released Parties are
                  indebted to the Company as of the Closing Date and that
                  neither Seller nor Seller Released Parties will owe any amount
                  to the Company that will be reflected as an asset on the
                  Closing Date Balance Sheet.

         10.      Offset Provisions. Notwithstanding any other provisions of 
this Agreement, in the event Seller becomes obligated to pay sums to Purchaser,
Rush 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
the Promissory Note in such amount or amounts as Purchaser (and Rush and any
Indemnified Party that is not promptly paid by Seller) is entitled to receive
from Seller, and any such offset shall be deemed to be a payment under the
Promissory Note.

         11.      Termination.

                  11.1     Termination of Agreement. Certain of the Parties may
         terminate this Agreement as provided below:

                           (a) Purchaser and Seller may terminate this Agreement
                  by mutual written consent at any time prior to the Closing;

                           (b) Purchaser may terminate this Agreement by giving
                  written notice to Seller on or before the Closing Date if
                  Purchaser is not satisfied



                                       49

<PAGE>   56



                  with the results of its continuing business, legal, and
                  accounting due diligence regarding the Company;

                           (c) Purchaser may terminate this Agreement by giving
                  written notice to Seller at any time prior to the Closing (i)
                  in the event the Company or Seller has breached any
                  representation, warranty or covenant contained in this
                  Agreement in any material respect, Purchaser has notified
                  Seller of the breach, and the breach has continued without
                  cure for a period of 30 days after the notice of breach or
                  (ii) if the Closing shall not have occurred on or before April
                  30, 1998, by reason of the failure of any condition precedent
                  under Section 8.1 hereof (unless the failure results primarily
                  from Purchaser itself breaching any representation, warranty
                  or covenant contained in this Agreement); and

                           (d) Seller may terminate this Agreement by giving
                  written notice to Purchaser at any time prior to the Closing
                  (i) in the event the Purchase has breached any representation,
                  warranty or covenant contained in this Agreement in any
                  material respect, Seller has notified Purchaser of the breach,
                  and the breach has continued without cure for a period of 30
                  days after the notice of breach or (ii) if the Closing shall
                  not have occurred on or before April 30, 1998, by reason of
                  the failure of any condition precedent under Section 8.2
                  hereof (unless the failure results primarily from the Company
                  or Seller themselves breaching any representation, warranty or
                  covenant contained in this Agreement).

                  11.2     Effect of Termination. If any Party terminates this
         Agreement pursuant to Section 11.1 above, all rights and obligations of
         the Parties hereunder shall terminate without any Liability of any
         Party to any other Party (except for any Liability of any Party then in
         breach).

         12.      Requirements of Securities Laws.

                  12.1     Accredited Investors. Seller recognizes that the 
         Option Stock is not being registered under the Securities Act in
         reliance upon an exemption from the Securities Act which is predicated,
         in part, on the representations and agreements of Seller set forth in
         this Agreement. Seller represents and warrants to Purchaser and Rush
         that she is an "accredited investor" as that term is defined in Rule
         501(a) of the Securities Act and that the Option Stock is being
         acquired solely for her own account for investment and not with a view
         to, or for offer or resale in connection with, a distribution thereof
         within the meaning of the Securities Act. Seller understands that the
         effect of such representation and warranty is that the Option Stock
         must be held indefinitely unless subsequently registered under the
         Securities Act or an exemption from such registration is available at
         the time for any proposed sale or other transfer thereof. Seller also
         understands that neither Purchaser nor Rush is under any obligation to
         file a registration statement under the Securities Act covering the
         Option Stock or to take any other action to enable Seller to transfer
         or otherwise dispose of the Option Stock. Seller represents that she
         has consulted with counsel in regard to the Securities Act and that she
         is fully familiar with the circumstances under



                                       50

<PAGE>   57



         which she is required to hold the Option Stock and the limitations upon
         the transfer or other disposition thereof. Seller acknowledges that
         Purchaser and Rush are relying upon the truth and accuracy of the
         foregoing representations and warranties in issuing the Option Stock
         under the Securities Act. Seller agrees to indemnify and hold Purchaser
         and Rush harmless against all liabilities, costs and expenses,
         including reasonable attorneys' fees, incurred by either Purchaser or
         Rush as a result of any sale, transfer or other disposition by him of
         all or any part of the Option Stock in violation of the Securities Act.

                  12.2     Legend. The certificates representing the Option 
         Stock shall bear the following legend:

                  "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE
                  BEEN ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN
                  REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
                  AMENDED. THESE SECURITIES MAY NOT BE SOLD OR
                  TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR
                  AN EXEMPTION THEREFROM UNDER SAID ACT.

                  12.3     SEC Documents. Seller acknowledges that she has been
         furnished by Rush with (a) a copy of the Annual Report on Form 10-K of
         Purchaser for the fiscal year ended December 31, 1996, in the form
         filed with the SEC, and (b) copies of all filings since December 31,
         1996, by Purchaser with the SEC in compliance with Section 13 or 14 of
         the Exchange Act. Seller represents that she has reviewed the foregoing
         documents and acknowledge that she has been afforded the opportunity to
         obtain any additional information necessary to verify the accuracy of
         the information contained in the foregoing documents, including the
         opportunity to ask questions of, and receive answers from, officers and
         representatives of Rush concerning Rush and the terms and conditions of
         the transactions contemplated by this Agreement.

         13.      Non-Competition Agreement.

                  13.1     Non-Competition. In consideration of the benefits of
         this Agreement to the Seller and as a material inducement to Purchaser
         and Rush to enter into this Agreement and pay the Purchase Price,
         Seller hereby covenants and agrees that, commencing on the Closing Date
         and ending on the later of (i) five years from the Closing Date, or
         (ii) three years following the date Seller ceases to be employed by
         Purchaser or an Affiliate of Purchaser, regardless of how such
         cessation of employment may be brought about; she shall not, and the
         Seller will cause her Affiliates and representatives 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 anywhere in the States of California, Arizona,
         New Mexico, Texas, Oklahoma, Louisiana, Arkansas, Tennessee,
         Mississippi, Alabama, Georgia or Florida, in any business activity in
         which the Company participates or participated as of the Closing



                                       51

<PAGE>   58



         Date; provided, however, the foregoing shall not prohibit the Seller
         and her representatives from purchasing and holding as an investment
         not more than 1% 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 Seller, her Affiliates and representatives do
         not participate in any way in the management, operation or control of
         such entity.

                  13.2     Judicial Reformation. Seller acknowledges that, given
         the nature of the Purchaser's business, the covenants contained in
         Section 13.1 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 Purchaser's and Rush's business and to protect their
         legitimate business interests. If, however, Section 13.1 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.

                  13.3     Customer Lists; Non-Solicitation. Seller hereby 
         further covenants and agrees that she shall not, and Seller will cause
         her Affiliates and representatives not to, directly or indirectly, for
         a period commencing on the Closing Date and ending on the later of (i)
         five years from the Closing Date, or (ii) three years following the
         date Seller ceases to be employed by Purchaser or an Affiliate of
         Purchaser, the Company or Rush (a) use or make known to any person or
         entity the names or addresses of any clients or customers of the
         Company or Purchaser or Rush 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, her Affiliates or 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 the Company or Purchaser or Rush, (c)
         solicit for employment, recruit, hire or attempt to recruit or hire any
         employees of the Company or Purchaser or Rush, nor (d) become the
         employee or consultant of or otherwise render services to, or own any
         interest in, any enterprise that directly or indirectly competes with
         the business engaged in by the Company as of the Closing Date.

                  13.4     Covenants Independent. The covenants of the Seller
         contained in Sections 13.1, 13.2 and 13.3 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 against
         Purchaser or Rush will not constitute a defense to the enforcement by
         Purchaser or Rush of said provisions. Seller understands that the
         provisions contained in Sections 13.1, 13.2 and 13.3 are essential
         elements of the transactions contemplated by this Agreement and, but
         for the agreement of Seller to Sections 13.1, 13.2 and 13.3, Purchaser
         and Rush would not have



                                       52

<PAGE>   59



         agreed to enter into this Agreement and the transactions contemplated
         herein. Seller has been advised to consult with counsel in order to be
         informed in all respects concerning the reasonableness and propriety of
         Sections 13.1, 13.2 and 13.3 with specific regard to the nature of the
         business conducted by the Company and Purchaser and Rush and Seller
         acknowledges that Sections 13.1, 13.2 and 13.3 are reasonable in all
         respects.

                  13.5     Remedies. In the event of a breach or a threatened 
         breach by either Seller of any of the provisions contained in Sections
         13.1, 13.2 or 13.3 of this Agreement, Seller acknowledges that
         Purchaser and Rush 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, Purchaser and Rush 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 equity, including, without limitation, the
         right to sue for damages.

                  13.6     Exceptions. Notwithstanding the foregoing provisions 
         of Article 13, Seller shall be entitled at all times from and after the
         Closing to (i) have membership in, hold office in and perform services
         on behalf of any trade association or similar organization, (ii)
         collect any accounts receivable transferred to Seller pursuant to
         Section 2.3(e), (iii) sell any inventory transferred to Seller pursuant
         to Section 2.3(a), (iv) solicit for employment and employ members of
         the immediate family of Seller, and (v) utilize the services of Susan
         Hubbert in a capacity not in competition with the Company's business so
         long as such utilization does not materially interfere with Ms.
         Hubbert's performance of services as an employee of the Company.

         14.      Survey.

                  14.1     Survey. Within 20 days from and after the date
         hereof, The Company agrees, and Seller agrees to cause the Company to,
         at the Company'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 or surveys of the Real
         Property (whether one or more, 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 at least one copy of each Survey plat
         and a certificate under the seal of the surveyor, which Survey 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, 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



                                       53

<PAGE>   60



                  benefit of and reliance by Rush Enterprises, Inc., Rush Retail
                  Centers, Inc. and Alamo Title Company, (ii) the description
                  contained hereon is correct, (iii) the Real Property 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 Real Property shown hereon
                  are correct, and (vi) the area of the Real 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 the Company's expense)
         the standard printed exceptions from the Owner Policy of Title
         Insurance to be delivered by Seller as hereinabove provided. 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 Real Property
         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. Without in any way
         limiting the foregoing, the surveyor shall provide separate written
         field note descriptions for the Real Property.

                  14.2     Remedies for Failure to Deliver Survey. In the event
         Seller does not cause the Survey to be delivered within such 20-day
         period, then and thereafter, Purchaser shall have the option to (a)
         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 Cash
         Consideration on the Closing Date), or (b) waive the Survey
         requirements and proceed to close the sale contemplated by this
         Agreement.

         15.      Title Commitment and Condition of Title.

                  15.1     Title Commitment. Within ten days from and after the 
         date hereof, at the Company's sole cost and expense, Seller agrees to
         cause the Company to, and the Company agrees to cause the Title Company
         to furnish Purchaser and its counsel a Commitment for Owner Policy of
         Title Insurance (the "Title Commitment") prepared and issued by the
         Title Company describing and covering the Real Property, listing the
         Company as the prospective named insured and showing as the policy
         amount an amount equal to the value of the Real Property as determined
         by the appraisal to be conducted pursuant to Section 8 hereof. The
         Title Commitment shall constitute the commitment of the



                                       54

<PAGE>   61



         Title Company to insure, by title insurance in the standard form
         promulgated by the Board of Insurance of the State of Texas, The
         Company's title to the Real Property to be good and indefeasible and
         subject to the standard printed exceptions except as modified below,
         but deleting (at the Company's expense) to the maximum extent permitted
         by applicable title insurance regulations the standard printed form
         survey exception from the Owner Policy of Title Insurance as
         hereinabove provided. 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 Commitment shall contain no exception for
         "visible and apparent easements" or for "public or private roads" or
         the like. The Title Commitment shall contain no exception for "rights
         of parties in possession".

                  15.2     UCC Reports. Within ten days from and after the date
         hereof, Seller shall cause the Company to, and the Company shall, at
         the Company's sole cost and expense, furnish to Purchaser a report (the
         "UCC Report") of searches made of the Uniform Commercial Code Records
         of Guadalupe County, Texas, of the Official Public Records of Real
         Property of Guadalupe County, Texas, and of the Office of the Secretary
         of State, State of Texas, or the proper offices in the State of Texas
         where Uniform Commercial Code records are maintained, which searches
         shall show that none of the Company's assets are subject to any lien or
         security interest (other than liens and security interests which are
         not objected to by Purchaser). An update of the searches (dated no more
         than two days prior to the Closing Date, but delivered prior to the
         Closing Date) shall be provided by Seller to Purchaser at the Company's
         sole cost and expense.

                  15.3     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 to the Real Property 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 twenty five 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 the Company's sole cost and
         expense, within such 25-day period. If Seller cannot cure the
         objections within such twenty-five 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 $25,000 or less, to cure and
         deduct the cost of such cure from the Cash Consideration; or (c) waive
         the objections, and proceed to close the transaction contemplated
         hereby. In the event, however, that a lien indebtedness against any of
         the Company's Assets (including past due taxes) is disclosed by the
         Title Commitment or the UCC Report, then Seller shall (y) discharge
         such lien



                                       55

<PAGE>   62



         indebtedness prior to the Closing, or (z) authorize the Title Company
         to discharge such lien indebtedness at the Closing out of the Cash
         Consideration, and all costs incurred in connection with discharging
         such lien indebtedness shall not count against the $25,000 amount
         referenced in clause (b) of the immediately preceding sentence.

         16.      Environmental Studies and Remediation Activities.

                  16.1     Environmental Studies. Seller shall cause the Company
         to, and the Company shall, at the Company's cost and expense, undertake
         or is undertaking a Phase I environmental site assessment ("ESA") with
         respect to the Real Property utilizing the party designated by
         Purchaser. Within 20 days after the date hereof, Seller shall provide
         to Purchaser, at the Company's sole cost and expense, copies of (a) all
         existing ESAs (whether Phase I, Phase II or otherwise) covering all or
         any portion of the Real Property, to the extent the same are in
         Seller's or the Company's possession or Seller or the Company have
         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, to the extent the same are in Seller's or the Company's
         possession or Seller or the Company have access to them (all of the
         foregoing information, whether obtained by Purchaser or provided by
         Seller, being hereinafter referred to as "Environmental Information").
         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 60 days from the date hereof, but in no
         event less than 20 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 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. Each of Seller and Company have granted and
         hereby grant to Purchaser and its contractors and representatives
         access to the Real 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 Company's business, and,
         upon completion of their activities on the Real Property, shall restore
         the Real Property as nearly as is reasonably possible to the condition
         it was in immediately prior to such activities.

                  16.2     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 Real 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 and Seller fails or refuses to remediate or otherwise
         cure or have cured 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



                                       56

<PAGE>   63



         notice thereof given to Seller prior to the Closing Date, in which
         event the parties hereto shall have no further obligations hereunder or
         (b) if the Environmental Condition can be remediated or cured for
         $25,000 or less, to remediate or cure and deduct the cost of such cure
         from the Cash Consideration.

                  16.3     No Waiver. It is expressly understood and agreed by
         Purchaser and Seller that nothing in this Article 16 shall in any way
         operate as a waiver of or limitation on the environmental
         indemnification obligations of Seller set forth in this Agreement, and
         such indemnification obligations shall apply without regard to whether
         (a) any Environmental Conditions are disclosed as existing on reports
         performed or commissioned by Seller, the Company or Purchaser, (b) any
         environmental remediation or curative actions are undertaken by
         Purchaser, the Company or Seller hereunder, or (c) Purchaser elects to
         waive remediation or other curative actions with respect to
         Environmental Conditions on the Real Property and to proceed to
         Closing.

         17.      Miscellaneous.

                  17.1     Damage to Assets. If, on or before the Closing Date, 
         the assets or properties of the Company 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 have
         the right, in its sole discretion, to either (i) reduce the Purchase
         Price by an amount equal to the difference between the insurance
         proceeds and the value of the damaged or destroyed asset or assets, and
         complete the purchase, or (ii) terminate this Agreement as provided by
         Section 11.1 hereof and not complete the purchase.

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

                  17.3     Further Actions. From time to time, at the request of
         any Party hereto, the other parties hereto shall execute and deliver
         such instruments and take such action as may be reasonably requested to
         evidence the transactions contemplated hereby.

                  17.4     Dispute Resolution. Except for the provisions of 
         Articles 7.4, 9 and 13 of this Agreement dealing with restrictive
         covenants and non-disclosure of confidential information and other
         disputes with respect to which the remedy of injunctive relief is
         sought as provided for in this Agreement, with respect to which
         Purchaser and Rush expressly reserve the right to immediately and
         without any negotiation or mediation as provided herein, petition a
         court directly for injunctive and other relief, the parties agree that
         each will attempt to resolve through negotiation any dispute, claim or
         controversy arising out of or relating to this Agreement prior to
         proceeding to arbitration as provided herein. Either party may initiate
         this agreement prior to filing for arbitration as provided herein.
         Either party may initiate negotiations by providing written notice in
         letter form to the other party, setting forth the subject of the
         dispute and the relief requested. The recipient of such notice will
         respond in writing within five



                                       57

<PAGE>   64



         days with a statement of its position on and recommended solution to
         the dispute. If the dispute is not resolved by this exchange of
         correspondence, then representatives of each party with full settlement
         authority will meet at a mutually agreeable time and place within ten
         days of the date of the initial notice in order to exchange relevant
         information and perspectives, and to attempt to resolve the dispute. If
         the dispute is not resolved by these negotiations, the matter will be
         submitted to a J.A.M.S., or its successor, for mediation. If the matter
         is not resolved by such mediation within 30 days of the initiation of
         negotiations, then either party may proceed with arbitration in
         accordance with this Agreement.

         Except for the provisions of Articles 7.4, 9 and 13 of this Agreement
         dealing with restrictive covenants and non-disclosure of confidential
         information and other disputes with respect to which the remedy of
         injunctive relief is sought as provided for in this Agreement, with
         respect to which Purchaser and Rush 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
         (the "AAA") 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 Fifty Thousand Dollars ($250,000),
         exclusive of interest, attorneys' fees and costs, 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 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. Each Seller, Purchaser and Rush hereby
         irrevocably waives and releases any right to recover such damages in
         excess of those damages authorized by this Section 17.4. 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.

                  17.5     Effect of Due Diligence. No investigation by or on
         behalf of Purchaser into the business, operations, prospects, assets or
         condition (financial or otherwise) of the Company shall diminish in any
         way the effect of any representations or warranties made by Seller and
         the Company in this Agreement or shall relieve Seller or the Company of
         any of its obligations under this Agreement.

                  17.6     Press Releases and Public Announcements. No Party 
         shall issue any press release or make any public announcement relating
         to the subject matter of this Agreement prior to the Closing without
         the prior written approval of Purchaser and Seller; provided, however,
         that any Party may make any public disclosure it believes in good faith
         is required by applicable law (in which case the disclosing Party will
         use its reasonable best efforts to advise the other Parties prior to
         making the disclosure).

                  17.7     No Third Party Beneficiaries. This Agreement shall 
         not confer any rights or remedies upon any Person other than the
         Parties and their respective successors and permitted assigns.

                  17.8     Entire Agreement. This Agreement (including the 
         documents referred to herein) constitutes the entire agreement among
         the Parties and supersedes any prior understandings, agreements or
         representations by or among the Parties, written or oral, to the extent
         they related in any way to the subject matter hereof, including without
         limitation that certain letter agreement dated November 10, 1997.

                  17.9     Succession and Assignment. This Agreement shall be
         binding upon and inure to the benefit of the Parties named herein and
         their respective successors and permitted assigns. No Party may assign
         either this Agreement or any of her or its rights, interests, or
         obligations hereunder without the prior



                                       59

<PAGE>   66



         written approval of Purchaser and Seller; provided, however, that
         Purchaser may (i) assign any or all of its rights and interests
         hereunder to one or more of its Affiliates and (ii) designate one or
         more of its Affiliates to perform its obligations hereunder (in any or
         all of which cases Purchaser nonetheless shall remain responsible for
         the performance of all of its obligations hereunder).

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

                  17.11    Headings. The section headings contained in this
         Agreement are inserted for convenience only and shall not affect in any

         service, telecopy, telex, ordinary mail, or electronic mail), but no
         such notice, request, demand, claim, or other communication shall be

                  17.13    Governing Law. This Agreement shall be governed by 
         and construed in accordance with the domestic laws of the State of
         Texas without giving effect to any choice or conflict of law provision
         or rule (whether of the State of Texas or any other jurisdiction) that
         would cause the application of the laws of any jurisdiction other than
         the State of Texas.

                  17.14    Amendments and Waivers. No amendment of any provision
         of this Agreement shall be valid unless the same shall be in writing
         and signed by Purchaser and Seller. No waiver by any Party of any
         default, misrepresentation or breach of warranty or covenant hereunder,
         whether intentional or not, shall be deemed to extend to any prior or
         subsequent default, misrepresentation or breach of warranty or covenant
         hereunder or affect in any way any rights arising by virtue of any
         prior or subsequent such occurrence.

                  17.15    Severability. Any term or provision of this Agreement
         that is invalid or unenforceable in any situation in any jurisdiction
         shall not affect the validity or enforceability of the remaining terms
         and provisions hereof or the validity or enforceability of the
         offending term or provision in any other situation or in any other
         jurisdiction.

                  17.16    Expenses. Each of Purchaser and Seller will bear her 
         own costs and expenses incurred in connection with this Agreement and
         the transactions contemplated hereby. Seller agrees that the Company
         has not borne or will bear any of Seller's costs and expenses in
         connection with this Agreement or any of the transactions contemplated
         hereby, other than her attorneys' fees, the fees of her accountants,
         the title policy, survey, environmental studies, inventory audit and
         appraisal of the Real Property, which shall be paid by the Company as
         provided in this Agreement.

                  17.17    Construction. The Parties have participated jointly 
         in the negotiation and drafting of this Agreement. In the event an
         ambiguity or question of intent or interpretation arises, this
         Agreement shall be construed as if drafted jointly by the Parties and
         no presumption or burden of proof shall arise favoring or disfavoring
         any Party by virtue of the authorship of any of the provisions of this
         Agreement. Any reference to any federal, state, local, or foreign
         statute or law shall be deemed also to refer to all rules and
         regulations promulgated thereunder, unless the context requires
         otherwise. The word "including" shall mean including without
         limitation. The Parties intend that each representation, warranty and
         covenant contained herein shall have independent significance. If any
         Party has breached any representation, warranty or covenant contained
         herein in any respect, the fact that there exists



                                       61

<PAGE>   68



         another representation, warranty or covenant relating to the same
         subject matter (regardless of the relative levels of specificity) which
         the Party has not breached shall not detract from or mitigate the fact
         that the Party is in breach of the first representation, warranty or
         covenant.

                  17.18    Incorporation of Exhibits, Annexes, and Schedules. 
         The Exhibits, Annexes, and Schedules identified in this Agreement are
         incorporated herein by reference and made a part hereof.

                  17.19    Specific Performance. Each of the Parties 
         acknowledges and agrees that the other Parties would be damaged
         irreparably in the event any of the provisions of this Agreement are
         not performed in accordance with their specific terms or otherwise are
         breached. Accordingly, each of the Parties agrees that the other
         Parties shall be entitled to an injunction or injunctions to prevent
         breaches of the provisions of this Agreement and to enforce
         specifically this Agreement and the terms and provisions hereof in any
         action instituted in any court of the United States or any state
         thereof having jurisdiction over the Parties and the matter, in
         addition to any other remedy to which they may be entitled, at law or
         in equity.
