                ARMOR HOLDINGS, INC. ANNOUNCES AGREEMENT
              TO ACQUIRE STEWART & STEVENSON SERVICES, INC.

     -- Transformational Acquisition Positions Armor Holdings as Prime Vehicle
     Contractor--

     -- Combined Business Expected to Have Attractive Growth Opportunities --

JACKSONVILLE, FLA. AND HOUSTON, TX., -- FEBRUARY 27, 2006 -- ARMOR HOLDINGS,
INC. (NYSE: AH), a leading manufacturer and distributor of security products and
vehicle armor systems serving military, law enforcement, homeland security and
commercial markets, announced today that it has signed a definitive agreement to
acquire STEWART & STEVENSON SERVICES, INC. (NYSE: SVC), a leading manufacturer
of military tactical wheeled vehicles including the Family of Medium Tactical
Vehicles (FMTV), the U.S. Army's primary transport platform.

Armor Holdings has agreed to acquire all of the outstanding stock of SVC for $35
per share in a cash merger transaction. The total value of the transaction is
expected to be approximately $755 million after deducting SVC's net cash balance
of $312 million as of January 31, 2006. The transaction is subject to SVC
shareholder approval, the expiration or termination of the Hart-Scott-Rodino
waiting period and other customary conditions. The transaction is expected to
close mid-year. Armor Holdings will finance the transaction through available
cash and with proceeds from new senior credit facilities.

Robert R. Schiller, President of Armor Holdings, said, "This is truly a
transformational event for our company. Stewart & Stevenson is one of the finest
manufacturers of military vehicles in the world. Our position as the leading
supplier of vehicular armor and safety systems for the up-armored HMMWV,
numerous heavy tactical vehicles, and work for Stewart & Stevenson on the FMTV,
has enabled us to grow our sales and earnings at excellent rates for the past
several years. We believe this opportunity to become a prime contractor within
the military's tactical wheeled vehicle fleet is extremely compelling. We expect
to benefit from Stewart & Stevenson's world-class fabrication and assembly
operations, strong research and development effort, and highly capable
management team."

Max L. Lukens, President and Chief Executive Officer of Stewart & Stevenson
commented, "Our Board of Directors unanimously concluded that this transaction
with Armor Holdings provides significant value for our shareholders and is in
the best interests of our customers and employees. Our Tactical Vehicle Systems
business led by Denny Dellinger and his team has developed a standard of
quality, reliability and vehicle readiness for the FMTV that we believe is
unmatched in the industry. Armor Holdings, through its Aerospace & Defense
Group, has a diversified portfolio of great products that it offers to the U.S.
Department of Defense and other customers in various parts of the world. I
believe the successful

track record and complementary strengths of these two organizations offer a
platform for future growth and expanded opportunities for the combined
businesses."

Mr. Schiller added, "We believe that the integration of Stewart & Stevenson will
further diversify our overall defense business, create improved multi-year
visibility for revenues, make appropriate use of our strong financial position,
and provide a wide variety of incremental growth opportunities. We expect the
FMTV program to deliver strong growth going into the second-half of this year
and to continue in 2007 and beyond. Based on this expectation and potential
synergies from the combination, we expect the acquisition to be accretive to
earnings in 2007. We are very excited to begin the process of integration and
creation of a company that is stronger than either of its predecessors was
individually."

Robert Mecredy, President of Armor Holdings Aerospace & Defense Group, said, "We
are very proud of the work we have done and the close relationships we have
built with the team at Stewart & Stevenson over the past several years. We are
extremely excited about now working full time with this incredibly talented and
capable organization, specifically to identify the many benefits that might
arise from our combination. Stewart & Stevenson's leadership as a premier
vehicle manufacturer brings to Armor Holdings a multi-year FMTV contract through
2008, and potentially well into the future. We believe that it positions us
extremely well for a wide range of high-priority procurement contracts in the
coming years. In our opinion, recent Defense budget actions to significantly
increase funding for the FMTV program underscore the significance of this
critical equipment to U.S. military operations abroad and for the mission of our
Guard and Reserve components. We are proud of what Armor Holdings has done for
our Service men and women and excited to increase our contribution through the
addition of Stewart & Stevenson to the Armor Holdings Aerospace & Defense
Group."

Armor Holdings was advised on the transaction by Pruzan & Co. LLC. Wachovia
Securities provided financing and a fairness opinion to Armor Holdings' Board of
Directors. The law firm of Kane Kessler, P.C. acted as legal counsel for Armor
Holdings.

Stewart & Stevenson's financial advisor was Merrill Lynch & Co., with Robinson
Partners acting as a consultant to the Company. The law firms of Fulbright &
Jaworski LLP and Wachtell, Lipton, Rosen & Katz acted as legal counsel for
Stewart & Stevenson.
