ITEM 1.  DESCRIPTION OF REGISTRANT'S SECURITIES TO BE REGISTERED.

      This registration statement relates to the registration of the Common
Stock, without par value (the "Common Stock"), of Stewart & Stevenson Services,
Inc., a Texas corporation (the "Company"), and the purchase rights associated
with the Common Stock. Set forth below is a brief description of certain rights
of the holders of the Common Stock and the associated purchase rights:

COMMON STOCK

      The aggregate number of shares of capital stock that the Company is
authorized to issue is 100,000,000 shares of Common Stock.

      The holders of Common Stock are entitled to one vote per share on all
matters to be voted upon by shareholders. Subject to preferences that may be
applicable to any outstanding senior security, holders of Common Stock are
entitled to receive ratably any dividends that may be declared by the Board of
Directors out of funds legally available for that purpose. If the Company
liquidates, dissolves or winds up, the holders of Common Stock are entitled to
share ratably in all assets remaining after payment of debts and liabilities and
subject to the liquidation preference of any outstanding senior security. The
Common Stock has no preemptive or conversion rights, other subscription rights,
or redemption or sinking fund provisions. All issued and outstanding shares of
Common Stock are fully paid and non-assessable.

RIGHTS TO PURCHASE COMMON SHARES

      On March 7, 1995, the Board of Directors of the Company declared a
distribution of one common share purchase right (a "Right") for each outstanding
share of the Common Stock (as defined in the Rights Agreement, the "Common
Shares"), of the Company. The distribution was paid on March 20, 1995 (the
"Record Date") to the shareholders of record on that date. Each Right entitles
the registered holder to purchase from the Company one-third (1/3) of a Common
Share of the Company, at a price of $30 per one-third of a Common Share (the
"Purchase Price"), under certain circumstances and subject to adjustment. The
description and terms of the Rights are set forth in a Rights Agreement (the
"Rights Agreement") dated March 13, 1995 between the Company and The Bank of New
York, as Rights Agent (the "Rights Agent").

      DETACHMENT OF RIGHTS, EXERCISE. Initially, the Rights will attach to all
Common Share certificates representing outstanding shares and no separate Right
Certificate (defined below) will be distributed. The Rights will separate from
the Common Shares and a Distribution Date will occur upon the earlier of (i) the
tenth day after a public announcement that a person or group of affiliated or
associated persons (an "Acquiring Person") has acquired beneficial ownership of
15% or more of the outstanding Voting Shares (as defined in the Rights
Agreement) of the Company, or (ii) the tenth business day following the
commencement or announcement of an intention to commence a tender offer or
exchange offer (other than the Company, any subsidiary of the Company, any
employee benefit plan of the Company or of any subsidiary of the Company, or any
Trustee of or fiduciary with respect to any such plan when acting in such
capacity) the consummation of which would result in the beneficial ownership by
a person or group of 15% or more of such outstanding Voting Shares.

      Until the Distribution Date (or earlier redemption or expiration of the
Rights) (i) the Rights will be evidenced, with respect to the Common Shares
outstanding on March 20, 1995, by certificates for outstanding Common Shares and
not by separate certificates evidencing the Rights registered in the name of the
holder thereof with a copy of the summary of rights to purchase Common Shares
included as Exhibit 3 hereto (the "Summary of Rights"), (ii) the Rights will be
transferred with and only with the Common Shares, (iii) new Common Share
certificates issued after March 20, 1995, upon transfer or new issuance of the
Common Shares, will contain a notation incorporating the Rights Agreement by
reference, and (iv) the surrender for transfer of any certificates for Common
Shares outstanding as of March 20, 1995, even without such notation or a copy of




the Summary of Rights being attached thereto, will also constitute the transfer
of the Rights associated with the Common Shares represented by such certificate.

      As soon as practicable following the Distribution Date, separate
certificates evidencing the Rights (the "Right Certificates") will be mailed to
holders of record of the Common Shares as of the close of business on the
Distribution Date and such separate Right Certificates alone will thereafter
evidence the Rights.

      The Rights are not exercisable until the Distribution Date. The Rights
will expire on March 20, 2005 (the "Final Expiration Date"), unless the Final
Expiration Date is extended or the Rights are earlier redeemed or exchanged by
the Company as described below.

      Subject to action of the Board of Directors of the Company pursuant to
Section 25 of the Rights Agreement, if a person or group were to acquire 15% or
more of the Voting Shares of the Company, each holder of a Right then
outstanding (other than Rights beneficially owned by the Acquiring Person which
would become null and void) shall thereafter have a right to receive, upon
exercise thereof at a price equal to the then current Purchase Price multiplied
by the number of one one-thirds of a Common Share for which a Right is then
exercisable, such number of Common Shares of the Company as shall equal the
result obtained by (x) multiplying the then current Purchase Price by the number
of one one-thirds of a Common Share for which a Right is then exercisable and
dividing that by (y) 50% of the then current per share market price of the
Company's Common Shares on the date such person became an Acquiring Person.

      If the Company were acquired in a merger or other business combination
transaction or more than 50% of its consolidated assets or earning power were
sold, proper provision will be made so that (i) each holder of a Right (except
as otherwise provided in the Rights Agreement) shall thereafter have the right
to receive, upon the exercise thereof such number of Common Shares of such
acquiring entity (including the Company as successor thereto or as the surviving
corporation), as shall be equal to the result obtained by (x) multiplying the
then current Purchase Price by the number of one one-thirds of a Common Share
for which a Right is then exercisable (without taking into account any
adjustment previously made pursuant to the preceding paragraph) and dividing
that product by (y) 50% of the current per share market price of the Common
Shares of such other person on the date of consummation of such consolidation,
merger, sale or transfer; (ii) the issuer of such Common Shares shall thereafter
be liable for, and shall assume, by virtue of such consolidation, merger, sale
or transfer, all the obligations and duties of the Company (the term "Company,"
as used herein, shall thereafter be deemed to refer to such issuer) and (iii)
such issuer shall take such steps in connection with such consummation as may be
necessary to assure that the provisions of the Rights Agreement shall thereafter
be applicable, as nearly as reasonably may be, in relation to the Common Shares
thereafter deliverable upon the exercise of the Rights.

      ANTIDILUTION AND OTHER ADJUSTMENTS. The number of securities or property
issuable upon exercise of the Rights, and the Purchase Price payable, are
subject to customary adjustments from time to time to prevent dilution.

      The number of outstanding Rights are also subject to adjustment in the
event of a stock split of the Common Shares or a stock dividend on the Common
Shares payable in Common Shares or subdivisions, consolidations or combinations
of the Common Shares occurring, in any such case, prior to the Distribution
Date.

      MANDATORY REDEMPTION AND EXCHANGE. At any time after the acquisition by a
person or group of affiliated or associated persons of beneficial ownership of
15% or more of the outstanding Voting Shares of the Company and before the
acquisition by a person or group of 50% or more of the outstanding Voting Shares
of the Company, the Board of Directors may, at its option, issue Common Shares
in mandatory redemption of, and in exchange for, all or part of the then
outstanding and exercisable Rights (other than Rights owned by such




person or group which would become null and void) at an exchange ratio of one
Common Share for each two Common Shares for which each Right is then
exercisable, subject to adjustment.

      REDEMPTION. At any time prior to the first public announcement that a
person or group has become the beneficial owner of 15% or more of the
outstanding Voting Shares, the Board of Directors of the Company may redeem all
but not less than all the then outstanding Rights at a price of $0.01 per Right
(the "Redemption Price"). The redemption of the Rights may be made effective at
such time, on such basis and with such conditions as the Board of Directors in
its sole discretion may establish. Immediately upon the action of the Board of
Directors ordering redemption of the Rights, the right to exercise the Rights
will terminate and the only right of the holders of Rights will be to receive
the Redemption Price.

      NO RIGHTS AS SHAREHOLDER. Until a Right is exercised, the holder thereof,
as such, will have no rights as a shareholder of the Company, including, without
limitation, the right to vote or to receive dividends.

      AMENDMENT OF RIGHTS. The terms of the Rights may be amended by the Board
of Directors of the Company without the consent of the holders of the Rights,
including an amendment to extend the Final Expiration Date, and, provided a
Distribution Date has not occurred, to extend the period during which the Rights
may be redeemed, except that after the first public announcement that a person
or group has become the beneficial owner of 15% or more of the outstanding
Voting Shares, no such amendment may materially and adversely affect the
interests of the holders of the Rights.

      The foregoing description of the Rights does not purport to be complete
and is qualified in its entirety by reference to the Rights Agreement, form of
Right Certificate, form of the Summary of Rights and the specimen of the legend
to be placed on new Common Share certificates, incorporated by reference herein.
