ADMINISTAFF ANNOUNCES SECOND WASHINGTON, D.C. AREA OFFICE

Company continues aggressive national expansion program

HOUSTON, TX – March 23, 2000 – Administaff, Inc. (NYSE: ASF), a leading Professional Employer Organization (PEO), today announced it is further expanding its operations by opening its second Washington, D.C. area office to serve local businesses and organizations. The new office – the 26th for the company – is located in McLean, Va., and officially opened for business on March 1, 2000. Administaff currently maintains an office in Beltsville, Md., and has plans to open a third regional office in the near future. The McLean, Va., office opening continues Administaff’s planned expansion program to establish 90 offices in 40 markets across the nation.

"The Washington, D.C./Baltimore area is Administaff’s fourth largest market in terms of potential clients," said Paul J. Sarvadi, Administaff president and chief executive officer. "The competition for talent among businesses in the region is immense, with companies striving to attract and retain quality employees. In addition, managers are trying to find more time to focus on core business issues. Administaff provides assistance on both fronts – relieving time pressures by helping business owners better manage their employer responsibilities while offering employee benefits comparable to those at Fortune 500 companies."

Mark Loving has been appointed district manager for the McLean, Va. office, a location chosen to provide excellent geographic access to the entire Northern Virginia and Washington,
