                         Report of Independent Auditors


Administrative Committee
Stewart & Stevenson 401(k) Savings Plan


We have audited the accompanying statement of net assets available for benefits
of the Stewart & Stevenson 401(k) Savings Plan as of December 31, 2001, and the
related statement of changes in net assets available for benefits for the year
then ended. These financial statements are the responsibility of the Plan's
management. Our responsibility is to express an opinion on these financial
statements based on our audit.

We conducted our audit in accordance with auditing standards generally accepted
in the United States. Those standards require that we plan and perform the audit
to obtain reasonable assurance about whether the financial statements are free
of material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audit provides a reasonable basis for our
opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the net assets available for benefits of the Plan at
December 31, 2001, and the changes in its net assets available for benefits for
the year then ended, in conformity with accounting principles generally accepted
in the United States.

Our audit was performed for the purpose of forming an opinion on the financial
statements taken as a whole. The accompanying supplemental schedule of nonexempt
transactions for the year ended December 31, 2001, and schedule of assets (held
at end of year) as of December 31, 2001, are presented for purposes of
additional analysis and are not a required part of the financial statements but
are supplementary information required by the Department of Labor's Rules and
Regulations for Reporting and Disclosure under the Employee Retirement Income
Security Act of 1974. These supplemental schedules are the responsibility of the
Plan's management. The supplemental schedules have been subjected to the
auditing procedures applied in our audit of the financial statements and, in our
opinion, are fairly stated in all material respects in relation to the financial
statements taken as a whole.

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Administrative Committee of the
Stewart & Stevenson 401(k) Savings Plan:

We have audited the accompanying statements of net assets available for benefits
of the Stewart & Stevenson 401(k) Savings Plan (the Plan) as of December 31,
2000 and 1999, and the related statement of changes in net assets available for
benefits for the year ended December 31, 2000. These financial statements and
supplemental schedules referred to below are the responsibility of the Plan's
administrator. Our responsibility is to express an opinion on these financial
statements and supplemental schedules based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States. Those standards require that we plan and perform the audit
to obtain reasonable assurance about whether the financial statements are free
of material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the net assets available for benefits of the Stewart &
Stevenson 401(k) Savings Plan as of December 31, 2000 and 1999, and the changes
in net assets available for benefits for the year ended December 31, 2000, in
conformity with accounting principles generally accepted in the United States.

Our audits were performed for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedule of assets (held
at end of year) as of December 31, 2000 (Schedule I), and schedule of nonexempt
transactions for the year ended December 31, 2000 (Schedule II), are presented
for the purpose of additional analysis and are not a required part of the basic
financial statements but are supplementary information required by the
Department of Labor's Rules and Regulations for Reporting and Disclosure under
the Employee Retirement Income Security Act of 1974. The supplemental schedules
have been subjected to the auditing procedures applied in the audits of the
basic financial statements and, in our opinion, are fairly stated in all
material respects in relation to the basic financial statements taken as a
whole.

Stewart & Stevenson 401(k) Savings Plan

Notes to Financial Statements


December 31, 2001


1. DESCRIPTION OF PLAN

GENERAL

The Stewart & Stevenson 401(k) Savings Plan (the "Plan") is a defined
contribution plan established effective January 1, 1994 for the benefit of
eligible employees of Stewart & Stevenson, Inc. and certain adopting
subsidiaries (collectively, the "Company") who have completed at least 30 days
of service. The Plan is subject to the provisions of the Employee Retirement
Income Security Act of 1974 ("ERISA").

The following description of the Plan is provided for general information only.
Participants should refer to the SUMMARY PLAN DESCRIPTION for a more complete
description of the Plan's provisions, a copy of which is available from the
Company.

CONTRIBUTIONS

Eligible employees are automatically enrolled for a 1% participant contribution
of their eligible compensation unless otherwise elected. Participants may elect
to make an additional contribution from 2% to 20% of their eligible
compensation, subject to certain limitations, as defined by the Internal Revenue
Code ("IRC"). The first 1% of participant contributions is matched dollar for
dollar ("Basic Match") by the Company, and participant contributions in excess
of 1% of compensation but no more than 6% are matched at 25% ("Supplemental
Match") by the Company. Participants may also make rollover contributions to the
Plan representing distributions from other qualified plans. Participants may
direct the investment of all contributions into one or more of the investment
options offered by the Plan.

VESTING

Participants are fully vested in their participant contributions, rollovers,
Basic Match, and the related earnings which have been credited to their
accounts. Participants shall have a 100% vested interest in their Supplemental
Match contributions upon attainment of age 65, the normal retirement age, or
upon death or disability, as defined by the Plan. Participants who terminate for
any other reason vest in their Supplemental Match contributions and related
earnings at a rate of 20% per year with full vesting after five years of
service. Forfeited amounts of nonvested accounts are used to reduce future
Supplemental Match or administrative expenses of the Plan.


                                                                               6

                   Notes to Financial Statements (continued)



1. DESCRIPTION OF PLAN (CONTINUED)

BENEFIT PAYMENTS

Benefits are payable to participants or to a designated beneficiary in the event
of their retirement, death, or termination of employment in the form of a lump
sum payment. In limited circumstances, account withdrawals may be made upon the
attainment of age 59 1/2 or in the event of financial hardship as defined in the
Plan.

PARTICIPANT LOANS

Participants may borrow from their accounts a minimum of $1,000 up to a maximum
equal to the lesser of $50,000 or 50% of their vested account balance. The loan
term may not exceed five years, except for loans used for the purchase of a
principal residence, which may be repaid over a longer period of time. Principal
and interest are paid ratably through payroll deductions.

ADMINISTRATIVE EXPENSES

The Company pays certain administrative expenses of the Plan.

PLAN TERMINATION

Although it has not expressed any intent to do so, the Company has the right
under the Plan to discontinue its contributions at any time and to terminate the
Plan subject to the provisions set forth in ERISA. In the event of Plan
termination, participants will become 100% vested in their account balances.

2. SUMMARY OF ACCOUNTING POLICIES

BASIS OF ACCOUNTING

The accompanying financial statements of the Plan have been prepared using the
accrual basis of accounting in accordance with accounting principles generally
accepted in the United States. Benefit payments are recorded when paid.



                                                                               7

                   Notes to Financial Statements (continued)



2. SUMMARY OF ACCOUNTING POLICIES (CONTINUED)

USE OF ESTIMATES

The preparation of financial statements in conformity with accounting principles
generally accepted in the United States requires management to make estimates
that affect the amounts reported in the financial statements and accompanying
notes and schedules. Actual results could differ from those estimates.

INVESTMENT VALUATION AND INCOME RECOGNITION

Investments in mutual funds and common stock are stated at fair value, based on
quotations obtained from national security exchanges. The investment in the
common collective trust fund is stated at fair value as determined by the
issuer, based on the fair value of the underlying investments.

Purchases and sales of securities are recorded on a trade-date basis. Interest
income is recorded on the accrual basis. Dividends are recorded on the
ex-dividend date.

RISKS AND UNCERTAINTIES

The Plan provides for various investments in a common collective trust fund,
mutual funds, and common stock. Investment securities, in general, are exposed
to various risks, such as interest rate, credit, and overall market volatility
risk. Due to the level of risk associated with certain investment securities, it
is reasonably possible that changes in the values of investment securities will
occur in the near term and that such change could materially affect the amounts
reported in the statement of net assets available for benefits and participant
account balances.



                                                                               8

4. INCOME TAX STATUS

The Plan has received a determination letter from the Internal Revenue Service
dated January 20, 2000, stating that the Plan is qualified under section 401(a)
of the IRC and, therefore, the related trust is exempt from taxation. Subsequent
to this issuance of the determination letter, the Plan was amended. Once
qualified, the Plan is required to operate in conformity with the IRC to
maintain its qualification. The Plan administrator believes the Plan is being
operated in compliance with the applicable requirements of the IRC and,
therefore, believes that the Plan, as amended, is qualified and the related
trust is tax exempt.
