     ROCHESTER, NY, March 28, 2006 — Paychex, Inc. (the “Company” or “Paychex”) (NASDAQ:PAYX) today announced record net income of $114.5 million, or $0.30 diluted earnings per share, for the three months ended February 28, 2006 (“the third quarter”), a 23% increase over net income of $92.8 million, or $0.24 diluted earnings per share, for the same period last year. Total revenues were $430.6 million, a 15% increase over $373.9 million for the same period last year.

     “We are very pleased with our results for the third quarter, which once again, produced record revenues and earnings. They were in line with our expectations and position us very well to achieve our full year guidance. The third quarter includes our most important selling season when we add approximately one-third of our new payroll clients for the year. We just completed an outstanding selling season and client year end which will position us for a good start in fiscal 2007,” commented Jonathan J. Judge, President and Chief Executive Officer of Paychex.

     Human Resource Services revenue increased 24% to $81.9 million for the third quarter. The increase for the third quarter reflects growth in the following services: Retirement Services increased 15% to $27.6 million, administrative fee revenue from Paychex Premier^(SM) Human Resources increased 54% to $13.0 million, Professional Employer Organization services increased 9% to $17.2 million, and revenues from other Human Resource Services increased 35% to $24.1 million.

     Growth in total expenses was 13% for the third quarter and 11% for the nine months ended February 28, 2006. The third quarter was impacted by higher commissions and bonus expenses as we exceeded our year-to-date sales targets. We also incurred higher expenses in the third quarter through our commitment to continuously improve client service by reducing the number of clients per payroll specialist. For the third quarter, our operating income was $160.6 million, an increase of 19% over the same period last year.

     Increases in interest on funds held for clients and corporate investment income were attributable to higher average interest rates and higher average investment balances, as summarized below:
