ADMINISTAFF NAMED ONE OF "BEST BIG COMPANIES IN AMERICA" BY FORBES MAGAZINE

HOUSTON, TX – January 8, 2001 – Administaff, Inc. (NYSE: ASF), the nation’s leading Professional Employer Organization (PEO), is included for the second time on the annual Forbes Platinum 400 list of the best big companies in America. Forbes released its annual Platinum 400 list in the magazine’s Jan. 8, 2001 issue, naming Administaff in the Business Services category.

In creating the list, Forbes identified over 1,300 companies with at least $1 billion in annual sales, then divided those companies into 23 categories. To make the Platinum 400, companies must be industry leaders in long-term and short-term return on capital, as well as sales and earnings growth. In addition, the companies must have "an innate ability to adapt to change, a hunger to innovate and go against the grain, resiliency in a down industry and amid doubts on Wall Street, and a relentless will to be miserly even in boom times," according to Forbes.

"We are proud to be named by Forbes as one of the best big companies in the United States," said Paul J. Sarvadi, Administaff president and chief executive officer. "This honor signifies the commitment of our people to deliver high-quality service while balancing growth and profitability."
