Group shall have any obligation to borrow from GMAC.

                          Borrowing Base Line of Credit

      Section 2.1 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 2.2 Establishment of Line of Credit. Subject to the terms and
conditions of this Agreement, GMAC hereby establishes a revolving line of credit
for Rush in an amount not to exceed the lesser of:

      (a) $13,500,000, or

      (b) the Collateral Formula Amount, as defined in Section 2.7.

The amount available for loan under this Article II is referred to as the "Line

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 2.3 Loans. Within 3 Business Days after each request made by Rush from

requested, up to the Line of Credit (each such advance hereinafter a "Credit
Advance"). The aggregate principal amounts so loaned and advanced and remaining

Advance shall be disbursed by GMAC from its Houston, Texas office and, upon such
disbursement being made, shall be charged to Rush's

account on GMAC's books and records. GMAC will render to Rush a statement at
least once each month of Rush's account which shall constitute an account stated
and shall be presumed to be correct.

      Section 2.4 Repayment. Rush 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, Rush shall execute and deliver such promissory note
or notes in the form then in use by GMAC (each such note being hereafter
referred to as a "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 Rush to execute and deliver such
Borrowing Base Promissory Note, or guaranty or guaranties, shall not affect
Rush's obligation to 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 Rush for the amount owed; if Rush
fails to question or otherwise contest the information on such statements within
10 days of receipt by Rush, Rush shall be deemed to agree with the information
on the statements, including the accuracy of GMAC's calculation of the amount

fee or premium or notice or penalty, repay all or any part of the Credit Line

repayment in full of the Credit Line Advances. Only one interest rate will apply
to the Credit Line Advances at any given time. The interest rate on the Credit
Line Advances will be determined from time to time at a rate equal to the Prime
Rate less 0.50 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 Rush has
paid GMAC all sums owing under this Agreement.

      Section 2.6 Permitted Use of Credit Advances. Each and every Credit
Advance by GMAC to Rush or on Rush'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; (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 GMAC.

      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.

      "Certification Report" shall mean that form of document attached hereto as

Guaranty Agreement,

the Rush Group hereby pledges, assigns and grants to GMAC a security interest in
the Parts Inventory (sometimes also referred to as the "Borrowing Base
Collateral"). The Rush Group shall execute and deliver to GMAC one or more
security agreements, documents, and financing statements, in form and substance
satisfactory to GMAC in the exercise of reasonable judgment of GMAC (but not
inconsistent with this Agreement as to any subject dealt with in this
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 be executed contemporaneously herewith shall be in the forms
required by GMAC. 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 such Dealer's place of business.

      Section 2.9 Obligations Regarding Borrowing Base Collateral. With respect
to the Borrowing Base Collateral, the Rush Group shall:

Dealer's Collateral Formula Amount as of the last day of the previous month.
GMAC may request, at any time, a parts inventory schedule for any or all
dealerships; the Rush Group shall provide such schedule within 48 hours of such
request.

      (d) The Rush Group shall arrange and have conducted, at least annually,
and at the respective Dealer's expense, a complete physical inventory of the New
Parts Inventory. Each such physical inventory shall be conducted by an
independent professional purveyor of such services and a certified copy of the
results thereof shall be promptly provided to GMAC.

      (e) The Rush Group shall keep its respective properties in good repair,
working order and condition and, from time to time, make all needful and proper
repairs, renewals, replacements, additions and improvements thereto, so that the
business carried on may be properly and advantageously conducted at all times in
accordance with prudent business management; provided, however, it is understood
that no member of the Rush Group shall be

                                      -11-

deemed to have violated the foregoing covenant on account of ordinary wear and
tear and damage due to casualty or any cause beyond such member of the Rush
Group's reasonable control.

                                   ARTICLE III

                                Real Estate Loans

      Section 3.1 Refinance of Real Estate Loans. On the condition that there
has been no Event of Default hereunder, GMAC shall permit the Rush Group to
refinance any Real Estate Loan. Upon payment of all amounts owing under any Real
Estate Loan, GMAC agrees to release the liens evidenced by the applicable
Mortgage. In addition to releasing the liens under said Mortgage, GMAC agrees to
also release, as applicable, any other liens on personal or other property which
pertains to the real estate covered by said Mortgage (by way of example,
security interests in equipment used at such location).

      Section 3.2 Cross-Collateralization of Real Estate. All Real Estate now or
hereafter subject to a security interest or other lien pursuant to any Mortgage
shall secure all Obligations, and any proceeds of the sale or other disposition
of any Real Estate pursuant to any Mortgage may be applied to any of the
Obligations as GMAC may elect. This agreement for cross collateralization shall
constitute and be deemed an amendment to and supplement each Mortgage now or
hereafter executed and shall augment and be in addition to and not in
substitution for any provision of any Mortgage, and shall not otherwise limit or
affect the rights and remedies of GMAC under any such Mortgage. Without limiting
the foregoing, it is acknowledged that one or more of the Rush Group may have
executed other documents which provide for cross collateralization of loans to
other members of the Rush Group. All such other documents shall remain in full
force and effect, and GMAC may exercise its rights and remedies under any of
such instruments in lieu of or in addition to exercising its rights under this
paragraph. It is acknowledged that, pursuant to the definition of "Real Estate
Loans" in Section 1.1(ag), the term "Real Estate Loans" does not include any
loans secured by real property located in California; therefore, this Section
3.2 shall not operate to cause any real property located in California to secure
any loans or other indebtedness not otherwise covered by specific loan
instruments executed in connection with any loan secured by real property in
California. In the event GMAC elects to exercise its lien rights against the
Real Estate owned by one member of the Rush Group (for purposes of this
paragraph the "Pledgor") for the payment of an Obligation of another member of
the Rush Group (for purposes of this paragraph the "Debtor") by virtue of this
cross-collateralization provision, the exercise of such liens shall be
contingent upon a default by the Debtor under the Obligation as well as the
giving of any required notices (if any) of default to the Debtor under the Loan
Documents evidencing that Obligation. Upon request by GMAC, any member of Rush
Group owning Real Estate shall execute a memorandum, in recordable form
sufficient for recording in the applicable real property or other records,
reciting that the liens against the Real Estate secure, in addition to any
Obligation recited in the applicable Mortgage, the Obligations under this
Agreement pursuant to this cross-collateralization provision.

GMAC, together with all accrued and unpaid expenses thereon, and applicable
costs and expenses as set forth in a promissory note or notes payable to the
order of GMAC, executed by the Borrowing Party and delivered to GMAC,
substantially in the form referenced in the GMAC Forms described below (the
"Wholesale Credit Note").

      The current interest rate charged by GMAC on Wholesale Floor Plan Loans
will be subject to the terms of the letter dated March 31, 2000 from J.F.

      Section 4.8 Dealer Obligations. The amounts and obligations now or
hereafter owing to GMAC by any members of the Rush Group under the Wholesale
Facility, Other Financing, Retail Financing, and any and all other indebtedness,
obligations, or liabilities of each member of the Rush Group whether direct or
indirect, liquidated or contingent, are referred to hereinafter as "Dealer
Obligations." The Rush Group hereby promises to pay to GMAC all Dealer
Obligations promptly on demand, except as may otherwise be set forth in
accordance with the express terms and conditions of this Agreement, the Loan
Documents and the GMAC Forms (as defined in Section 4.10).

      Section 4.9 Absolute Discretion of GMAC. The amount, terms, conditions,
interest rate, repayment terms, advance rate, existence, documentation, and
administration of the Wholesale Facility will, at all times, be subject to
change, suspension, and cancellation at the sole, absolute discretion of GMAC,
notwithstanding anything herein or otherwise to the contrary. Nothing contained
in this Agreement will, at any time, obligate GMAC to provide Other Financing or
Retail Financing to any member of the Rush Group or any customer of any member
of the Rush Group. The making and amount of any Other Financing or Retail
Financing will be in the sole, absolute discretion of GMAC. If GMAC elects to
suspend or cancel financing under this Agreement, the following notice
provisions shall apply: (i) if there is no default of any nature by any member
of the Rush Group, GMAC shall not make the suspension or cancellation effective
earlier than 120 days after notice to Rush; (ii) if there is any default of any
nature by any member of the Rush Group, GMAC may make suspension or cancellation
effective immediately upon notice of same.

      Section 4.10 Documentation of Dealer Obligations. Concurrently with the
execution and delivery of a Wholesale Facility, the appropriate member(s) of the
Rush Group will duly execute and deliver to GMAC at least one original of each
of the documents, instruments, or agreements (the "GMAC Forms") to evidence the
parties' intentions with respect to Dealer Obligations. Copies of the GMAC Forms
have been provided to Rush. The appropriate member(s) of the Rush Group will
duly execute and deliver to GMAC such other documents, instruments, or
agreements and any amendments thereto with respect to the Dealer Obligations, as
GMAC may customarily require from time to time. The existence of this Agreement,
representations, covenants, terms of default, and the like is in no way intended
to alter the demand nature of all Dealer Obligations which in every instance are
subject to change, suspension, and cancellation at the sole, absolute discretion
of GMAC.

It is acknowledged that the documentation of the Dealer Obligations may vary
from state to state, and the GMAC Forms to be executed by the members of the
Rush Group shall be in conformity with GMAC's practice in a particular state.

      (a) as to each member of the Rush Group, as applicable, (i) the prompt and
complete payment of the Wholesale Credit Advances, (ii) the performance of any

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. The 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 any member of the Rush Group 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. The Rush 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 the Rush Group,
in the case of insurance proceeds arising from the loss or damage of
improvements to the 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, the 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. Each member of the Rush Group 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 any
member of the Rush Group 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 any member of the Rush Group's
obligations hereunder), and for making all determinations and decisions with
respect to such policies of insurance. In the event any member of the Rush Group
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
such member of the 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. In addition, each member of the Rush Group

                                      -22-
<PAGE>

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.

      Section 7.11 Environmental Matters.

      (a) From the Effective Date, no member of the Rush Group nor any of their
respective agents, authorized representatives and employees (collectively
"Agents") shall engage in any of the following prohibited activities, and the
Rush Group will use its best and diligent efforts to see that its invitees,
tenants and contractors, and such persons' employees, agents, and invitees,
shall not:

            (i) cause or permit any release, discharge, or threat of release of
      Hazardous Material on or from any Facility.

            (ii) cause or permit any manufacturing, transporting, spilling,
      leaking, or dumping of Hazardous Material in or on any portion of any
      Facility, except in the ordinary course of the Rush Group's business on
      the Facility and in a manner not to allow any contamination of the
      Facility and in accordance with all federal, state and local Laws relating
      to Hazardous Material or other environmental matters.

            (iii) cause or permit any holding, handling or retaining of
      Hazardous Material in or on any portion of any Facility, except in the
      ordinary course of the Rush Group's business on the Facility and in a
      manner not to allow any contamination of the Facility and in accordance
      with all federal, state and local Laws relating to Hazardous Material or
      other environmental matters.

            (iv) otherwise place, keep, or maintain, or allow to be placed,
      kept, or maintained, any Hazardous Material on any portion of any
      Facility, except in the ordinary course of the Rush Group's business on
      the Facility and in a manner not to allow any contamination of the
      Facility and in accordance with all federal, state and local Laws relating
      to Hazardous Material or other environmental matters.

The Rush Group and its Agents will comply, and cause all Facilities to comply,
with all Laws of all authorities having jurisdiction over the Rush Group or its
Agents, any Facility, or the use of the Facility and pertaining to any Hazardous
Material.

      (b) If Hazardous Material is discovered on any Facility, the Rush Group
will pay (or cause those responsible to pay) immediately when due the cost of
removal of any Hazardous Material from the Facility (or other appropriate
remediation of the Hazardous Material) in compliance with all governmental
requirements, and keep the entire Facility free of any lien imposed pursuant to
any Laws having to do with the removal of Hazardous Material. Within 30 days
after demand by GMAC, the Rush Group will obtain and deliver to GMAC a bond,
letter of credit, or similar financial assurance for the benefit of GMAC,
evidencing, to GMAC's satisfaction in its sole, absolute discretion, that the
necessary funds are available to pay the cost

                                      -23-
<PAGE>

of removing, treating, and disposing of all Hazardous Material on the Facility
or any contamination caused thereby, and discharging any assessments or liens
which may be established on the Facility as a result thereof.

      (c) Each member of the Rush Group will:

            (i) Give written notice to GMAC immediately upon its acquiring
      knowledge of the presence of any Hazardous Material on any Facility (other
      than that used in the ordinary course of the Rush Group's business) or of
      any Hazardous Material contamination thereon, with a full description
      thereof;

            (ii) Immediately advise GMAC in writing of any notices received by
      it or its Agents alleging that any Facility contains Hazardous Material or
      contamination thereof, or that a violation or potential violation of any
      Hazardous Material Laws by the Rush Group or its agents, or the Facility
      exists;

            (iii) Immediately advise GMAC in writing upon discovery of any and
      all enforcement, cleanup, removal or other governmental or regulatory
      actions instituted, completed or threatened with respect to any Facility
      or any real estate adjoining the Facility; and

            (iv) Immediately advise GMAC in writing upon the Rush Group's
      discovery or any discovery by its 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 7.11(c)(iv) is intended or shall operate to
      create a duty on the part of the Rush Group or any of its Agents to
      inquire as to the condition (environmental or otherwise) of any property
      not owned or leased by the 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 the Rush Group's business)
to be removed therefrom or remediated on site if cost effective and permitted by
law. In such 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 the
Rush Group on demand. The Rush Group will give to GMAC and its Agents access to
the Facility for such purposes and the 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 exists
(other than in the ordinary course of the Rush Group's business), GMAC may
notify the Rush Group in writing

                                      -24-
<PAGE>

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 the 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 7.11. The 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). The Rush Group will comply, at
their sole cost and expense, with all recommendations contained in the Audit(s)
to the extent necessary to bring the Rush Group into compliance with the other
provisions of this Section 7.11, including any recommendations for additional
testing and studies to detect the presence of Hazardous Material, or to
otherwise confirm and verify the Rush Group's compliance with the provisions of
this Section 7.11, to the extent required by GMAC.

      (f) The representations and obligations of the Rush Group under this
Section 7.11 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 the Rush Group under this Section
7.11 shall remain in full force and effect.

      Section 7.12 Indemnification. The 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, 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 the 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 the 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 the 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 7.12 will
survive repayment of the Loans or other obligation to GMAC in full and
expiration or termination of this Agreement.

                                      -25-

      Section 7.13 Further Assurances. At its costs and expense, upon request of
GMAC, the 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 7.14 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 the Dealers
under Article IV. From time to time GMAC may require the 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.

and Retail Facility under Article IV (the Wholesale Floor Plan Loans).

      Section 11.2 Specific Remedies. GMAC shall have the right to:

      (a) institute proceedings to collect all or a portion of the Indebtedness

GMAC against any amount owing by the 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;

            (iii) may notify all such account, contract right, or other debtors
      of GMAC's interest therein and require direct payment to GMAC of such
      obligations;

            (iv) may receive, sign, endorse, and deliver in its name or the name
      of any member of the Rush Group any and all notes, instruments, documents,
      titles, negotiable instruments and the like necessary and appropriate to

            (v) is hereby constituted and appointed by each member of the Rush
      Group as its attorney-in-fact with power to accept and to receipt and
      endorse such member of the Rush Group's names upon any notes, acceptances,
      checks, drafts, money orders or other evidences of payment or Collateral
      that may come into GMAC's possession; to notify the Post Office
      authorities to change the address for delivery of mail addressed to each

      gross negligence and willful misconduct, all acts of said attorney or
      designee are hereby ratified and approved, and said attorney or designee
      shall not be liable for any acts of omission or commission, nor for any
      error of judgment or mistake of act or law made in good faith; this power
      being coupled with an interest is irrevocable while any of the Obligations

      (d) subject to any specific, contrary provision in any other security
agreement executed now or in the future: sell or lease the Collateral, or any
portion thereof, after giving 5 days' written notice, at public or private sale.
The sale by GMAC of less than the whole of the Collateral shall not exhaust the
power 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 Collateral. The decision to sell all or only a portion of the Collateral
at any sale shall be at the sole discretion of Secured Party.

      (e) require the Rush Group to assemble all or any of the Collateral
(except Real Estate) and make it available to GMAC at a place to be designated

Borrowing Base Loans (Article II), Real Estate Loans (Article III), Wholesale
Floor Plan Loans (Article IV) to be immediately due and payable without further
demand and may invoke the power of sale and any other remedies permitted by
applicable law or provided in this Agreement or any of the other Loan Documents.
The Rush Group and each Guarantor (as applicable) expressly waive all
presentations for payment, notices of intention to accelerate maturity, notices
of acceleration of maturity, notices of intention to demand payment, demands for
payment, protests, and notices of protest.

The Rush Group agrees that the sale by GMAC of any new or unused property
repossessed by GMAC to the original seller thereof, or to any person designated
by such seller, at the invoice cost thereof to the Rush Group less any credits
granted to the 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. The 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 11.3 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 in equity.
All of GMAC's rights and remedies may be enforced successively or concurrently.
GMAC's rights shall include all rights of a secured party under the Uniform
Commercial Code applicable in any particular state.

      Section 11.4 Expenses. The 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.

      Section 11.5 Proceeds. Proceeds realized by GMAC on the sale or other
disposition of the Collateral, after payment of all expenses incurred by GMAC in
enforcing the Indebtedness or

                                      -33-
<PAGE>

in retaking, holding, preparing for sale or lease, selling, leasing or otherwise
disposing of or realizing on the Collateral or the Indebtedness, shall be
applied by GMAC to the remaining Indebtedness in such manner as GMAC shall
elect.

      Section 11.6 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 11.7 No Agency. Nothing herein contained shall be construed to
constitute any member of the Rush Group 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 the
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 the Rush Group
of any of the terms and conditions thereof.

                                   ARTICLE XII

                                  Miscellaneous

      Section 12.1 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 12.1 shall create a presumption as to the existence and
amounts of the foregoing, absent manifest error. However, the 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 the Rush Group to contest the accuracy
shall constitute conclusive evidence of its accuracy. If the Rush Group contests
the accuracy within 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.

insist, or any election by GMAC not to insist, upon any member of the Rush
Group's strict performance of any of the terms, provisions or conditions of the

provision or condition thereof; and GMAC shall have the right at any time
thereafter to insist upon strict performance by such member of the Rush Group of
any and all of same. Specifically, no Advance by GMAC when there exists an Event
of Default under Article X shall in any way preclude GMAC from thereafter
declaring such failure to comply to be an Event of Default hereunder.

      Section 12.4 Survival. All agreements, representations, warranties and
covenants of each member of the Rush Group 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 any member of the Rush Group 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 12.5 Limitations on Interest. All agreements between GMAC, any
member of the Rush Group, 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

                                      -36-
<PAGE>

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 the applicable member(s) of the Rush Group. 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 such full period shall not
exceed the maximum amount permitted by applicable law. This paragraph shall
control all agreements between GMAC and any member of the Rush Group.

      Section 12.6 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 12.7 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 12.7. 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
the Rush Group.

      Section 12.8 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 12.9 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 12.10 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

                                      -37-
<PAGE>

provision shall govern any such satisfaction requirements, consents, approvals
or exercise of judgment required in connection with any of the Loan Documents.

      Section 12.11 No Third Party Beneficiary. This Agreement is for the sole
benefit of GMAC and the Rush Group and is not for the benefit of any third
party.

      Section 12.12 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 the Rush Group or has power over the daily
management functions and operating decisions made by the 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 the Rush Group. The relationship of GMAC and the
Rush Group is and at all times shall be solely that of debtor and creditor.

      Section 12.13 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, no member of the Rush
Group shall assign or encumber this Agreement or any rights herein, it being
expressly understood and agreed that the rights of the members of the Rush Group
hereunder are not assignable.

      Section 12.14 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 each member of the Rush Group in this Agreement shall be joint and
several obligations of each member of the Rush Group.

      Section 12.15 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 12.16 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 12.17 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 12.18 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, 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.
