FOR IMMEDIATE RELEASE

STEWART & STEVENSON SERVICES, INC. ANNOUNCES LOCATION OF

MAY 16, 2006 ADJOURNED SPECIAL MEETING OF SHAREHOLDERS

HOUSTON, TX – May 10, 2006 – Stewart & Stevenson Services, Inc. (NYSE: SVC) today announced that its special meeting of shareholders, which was adjourned yesterday to Tuesday, May 16, 2006, at 4:00 p.m., Houston Time, will be held at Hilton Houston Post Oak, 2001 Post Oak Blvd., Houston, TX.

As previously announced, the special meeting was adjourned in order to allow additional time for Stewart & Stevenson shareholders to evaluate the proposed merger with Armor Holdings, Inc. (NYSE: AH), the terms of which remain in effect through November 27, 2006 as set forth in the merger agreement, which was filed with Securities and Exchange Commission (SEC) on March 3, 2006, and the Company’s definitive proxy statement, which was filed with the SEC on April 7, 2006. Stewart & Stevenson’s Board of Directors unanimously recommends that shareholders vote “FOR” the proposed merger with Armor Holdings. The record date for shareholders entitled to vote at the meeting remains April 5, 2006.

Stewart & Stevenson shareholders are reminded that their vote is important, and a failure to vote has the same effect as a vote against the merger proposal. Shareholders may vote their shares by telephone or by the Internet, and are advised that if they have any questions or need any assistance in voting their shares, they should contact Stewart & Stevenson’s proxy solicitor, MacKenzie Partners, Inc. Toll-Free at 800-322-2885. Shareholders are urged to act promptly. The transaction is expected to close promptly after receipt of Stewart & Stevenson shareholder approval.

The Company noted that three leading proxy advisory firms – Institutional Shareholder Services, Glass Lewis and Proxy Governance – endorsed Stewart & Stevenson’s merger with Armor Holdings and recommended that Stewart & Stevenson shareholders vote in favor of the proposed merger.

As previously announced, Stewart & Stevenson and Armor Holdings entered into a definitive merger agreement on February 27, 2006, pursuant to which Armor Holdings would acquire all of the outstanding common stock of Stewart & Stevenson for $35.00 per share in cash. On April 19, 2006, the U.S. Department of Justice and the U.S. Federal Trade Commission granted early termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, in connection with the proposed transaction.

Shareholders are encouraged to read Stewart & Stevenson’s definitive proxy materials in their entirety as they provide, among other things, a detailed discussion of the process that led to the proposed merger and the reasons behind the Stewart & Stevenson Board of Directors’ unanimous recommendation that shareholders vote FOR the approval and adoption of the merger agreement and the merger.
