Item 1.01 Entry into a Material Definitive Agreement

Under the ANSYS, Inc. (the "Company") Amended and Restated 1996 Stock Option and
Grant Plan (the "Plan"), each independent director who is serving as a director
of the Company on the fifth business day after each annual meeting of
stockholders is automatically granted on such day non-qualified stock options to
acquire 24,000 shares of the Company's common stock. Notwithstanding such
provision, on May 10, 2005, the Board of Directors of the Company determined
that, solely with respect to the option grant related to the 2005 annual meeting
of stockholders, each independent director would be granted options to purchase
12,000 shares of common stock in lieu of the options to purchase 24,000 shares
provided for in the Plan. No other terms of the Plan or any option grant were
altered.
