<DIV align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">The securities being registered pursuant to the Rush Enterprises, Inc. Deferred Compensation
Plan (the &#147;Plan&#148;) represent obligations (the &#147;Obligations&#148;) of the Company to pay deferred
compensation to selected employees and directors in the future according to the terms of the Plan.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">The Company may establish a &#147;rabbi trust&#148; to serve as a source of funds from which it can
satisfy the Obligations. Assets of any rabbi trust will at all times be subject to the claims of
the Company&#146;s general creditors. Participants in the Plan will have no rights to any assets held
by a rabbi trust, except as general creditors of the Company.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">The Obligations are general unsecured obligations of the Company that are subject to the
claims of its general creditors and rank equally with other unsecured and unsubordinated
indebtedness of the Company outstanding from time to time. With respect to their recordkeeping
account balances under the Plan, participants and their beneficiaries will be unsecured general
creditors of the Company. The Plan is considered entirely unfunded for tax purposes.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">The amount to be deferred by each participant in the Plan will be determined in accordance
with the Plan based on the participant&#146;s elections. Matching contributions by the Company to a
participant&#146;s recordkeeping account may also be made at the sole discretion of the Company. Amounts
credited to a participant&#146;s recordkeeping account will be credited with earnings in accordance with
the deemed investment options selected by the participant from time to time pursuant to which
deemed earnings or losses are credited or debited, as the case may be, to the participant&#146;s
account. Amounts credited to a participant&#146;s recordkeeping account consisting of restricted stock
unit grants or dividend equivalents paid on restricted stock unit grants shall be credited with the
number of units that are equal to the number of full and fractional shares as could be purchased at
fair market value on the first trading date preceding the date the participant elected the deferral
to his recordkeeping account. Any dividends payable on shares of the Company&#146;s common stock shall
be credited to the participant&#146;s account in an amount equal to that number of units equal to the
number of full or fractional hypothetical shares in the participant&#146;s recordkeeping account
immediately prior to the record date for such dividend.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">The Obligations are not convertible into any other security of the Company and there is no
trading market for the Obligations.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">The Obligations are payable upon a participant&#146;s termination of employment, death or on the
date(s) selected by a participant in accordance with the terms of the Plan, and are denominated and
payable in cash, except for distributions from the participant&#146;s restricted stock subaccount which
shall be payable in whole shares of the Company&#146;s common stock and in cash for fractional shares.
The Company may also make a distribution upon an unforeseeable emergency with respect to a
participant.

limits the liability of its directors. Specifically, Article&nbsp;VIII provides in part that:
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">A director shall not be liable to the Company or its shareholders for monetary damages for an
act or omission in such director&#146;s capacity as director, except for liability for (i)&nbsp;any breach of
the director&#146;s duty of loyalty to the Company or its shareholders, (ii)&nbsp;any act or omission not in
good faith that constitutes a breach of duty of the director to the Company or any act or omission
that involves intentional misconduct or a knowing violation of the law, (iii)&nbsp;any transaction from
which the director received an improper benefit, whether or not the benefit resulted from an action
taken within the scope of the director&#146;s office or (iv)&nbsp;any act or omission for which the liability
of the director is expressly provided by statute. If either the Texas Business Corporation Act
(the &#147;TBCA&#148;), the Texas Miscellaneous Corporation Laws Act (the &#147;TMCLA&#148;) or any other applicable
Texas statute hereafter is amended to authorize the further elimination or limitation of the
liability of the director, then the liability of a director of the Company, in addition to the
limitation on liability provided in the Restated Articles, shall be limited to the fullest extent
permitted by such amended act.
</DIV>

the Company&#146;s directors and officers. Specifically, Article&nbsp;VIII provides in part that:
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">The Company hereby elects to and does hereby indemnify the following persons to the fullest
extent permitted or required by the TBCA: (a)&nbsp;any person who is or was a director or officer of the
Company, (b)&nbsp;any person who, while a director or officer of the Company, is or was serving at the
request of the Company as a director, officer, partner, venturer, proprietor, trustee, employee,
agent or similar functionary of another foreign or domestic corporation, partnership, joint
venture, sole proprietorship, trust, employee benefit plan or other enterprise and (c)&nbsp;any person
who is not or was not a director or officer of the Company but who is or was serving at the request
of the Company as a director, officer, partner, venturer, proprietor, trustee, employee, agent or
similar functionary of another foreign or domestic corporation, partnership, joint venture, sole
proprietorship, trust, employee benefit plan or other enterprise. Such obligation to so indemnify
and to so make such determinations may be specifically enforced by resort to any court of competent
jurisdiction. Further, the Company shall pay or reimburse the reasonable expenses of such persons
covered hereby in advance of the final disposition of any proceeding to the fullest extent
permitted by the TBCA and subject to the conditions thereof. If the TBCA or any other applicable
Texas statute is hereafter amended to authorize a corporation to further indemnify the above described persons, the Company shall, in addition to the indemnification provided
herein, indemnify such persons to the fullest extent permitted or required under such amended act
or statute.

under the laws of the State of Texas became subject to the Texas Business Organizations Code, as
amended (the &#147;TBOC&#148;) which is the successor statute to the TBCA and the TMCLA. Chapter&nbsp;8 of the
TBOC permits the Company, in certain circumstances, to indemnify any present or former director,
officer, employee or agent of the Company against judgments, penalties, fines, settlements and
reasonable expenses incurred in connection with a proceeding in which any such person was, is or is
threatened to be, made a party by reason of holding such office or position, but only to a limited
extent for obligations resulting from a proceeding in which the person is found liable on the basis
that a personal benefit was improperly received or in circumstances in which the person is found
liable in a derivative suit brought on behalf of the Company.

with certain of its directors and officers (each, an &#147;Indemnitee&#148;). The indemnification agreement
provides that the Company will (subject to certain exceptions) defend, hold harmless and indemnify
the Indemnitee to the fullest extent permitted by law in connection with any proceeding covered by
the indemnification agreement. The indemnification agreement also provides that the Company will,
to the fullest extent permitted by law, advance all expenses incurred by an Indemnitee in
connection with a proceeding covered by the indemnification agreement. A form of the indemnity
agreement is filed as Exhibit&nbsp;10.1 of the Company&#146;s Current Report on Form 8-K, filed with the
