                         ADMINISTAFF EXECUTIVE OFFICERS
                        TO IMPLEMENT 10b5-1 TRADING PLANS




HOUSTON - March 24, 2003 - Administaff, Inc. (NYSE: ASF), the nation's leading
Professional Employer Organization (PEO), today announced that Paul J. Sarvadi,
its president and chief executive officer, and Richard G. Rawson, executive vice
president of administration and chief financial officer, have established
structured, prearranged trading plans to sell a portion of their shares in the
company over a designated period in accordance with Rule 10b5-1 of the
Securities Exchange Act of 1934. The plans are being established to diversify
Sarvadi's and Rawson's holdings of Administaff stock in an orderly manner. The
plans are separate and unrelated to each other, and have been initiated during
the company's open window period for insider transactions.

Rule 10b5-1 permits the implementation of a written plan for selling stock at
times when insiders are not in possession of material nonpublic information and
allows them to sell stock on a regular basis and in a non-discretionary manner,
regardless of any subsequent material nonpublic information they receive.

Sarvadi, who beneficially owns 3,201,900 shares and options to purchase an
additional 270,000 shares, has implemented a plan whereby two of his family
limited partnerships may sell a maximum of 540,000 shares over a three-year
period, subject to the achievement of predetermined stock prices. Rawson, who
beneficially owns 1,318,693 shares and options to purchase an additional 210,000
shares, has established a plan allowing for the sale by two family limited
partnerships of 108,000 shares over a two-year period, subject to the
achievement of predetermined stock prices. The number of shares eligible for
sale under each of the plans will be adjusted to reflect stock dividends, splits
and similar events. The shares to be sold represent


                                     (more)



approximately 15.6 percent of Sarvadi's holdings, approximately 7.1 percent of
Rawson's holdings, and collectively less than 2.5 percent of Administaff's
outstanding shares.

Other officers and directors of the company may establish plans in compliance
with Rule 10b5-1 in the future. Except as may be required by law, the company
does not undertake to report plans by other company officers or directors, nor
to report modifications, terminations, transactions or other activities under
Sarvadi's or Rawson's plans or the plan of any other officer or director.

Administaff is a leading personnel management company that serves as a
full-service human resources department for small and medium-sized businesses
throughout the United States. The company operates 38 sales offices in 21 major
