STOCK OPTION GRANTS

     The following table sets forth further information regarding individual
grants of options for Synopsys common shares during fiscal 2001 for each of the
named executive officers. All grants for each of the named executive officers
were made pursuant to the 1992 stock option plan. In accordance with the rules
of the SEC, the table sets forth the hypothetical gains or "option spreads" that
would exist for the options at the end of their respective ten-year terms based
on assumed annualized rates of compound stock price appreciation of 5% and 10%
from the dates the options were granted to the end of their respective option
terms. Actual gains, if any, on option exercises are dependent on the future
performance of the Synopsys common shares and overall market conditions. There
can be no assurance that the potential realizable values shown in this table
will be achieved. No stock appreciation rights were granted to such officers
during fiscal 2001.

 EMPLOYMENT CONTRACTS, TERMINATION OF EMPLOYMENT ARRANGEMENTS AND CHANGE OF
 CONTROL AGREEMENTS

     Under Synopsys' 1992 stock option plan, in the event of certain changes in
the ownership or control of Synopsys involving a "Corporate Transaction," which
includes an acquisition of Synopsys by merger or asset sale, all outstanding
options under the 1992 stock option plan will automatically become exercisable,
unless the option is assumed by the successor corporation, or parent thereof, or
replaced by a comparable option to purchase shares of the capital stock of the
successor corporation, or parent thereof.

     In addition, in the event of a successful hostile tender offer for more
than 50% of the outstanding Synopsys common shares or a change in the majority
of the Synopsys board of directors as a result of one or more contested
elections for membership on the Synopsys board of directors, the administrator
of the 1992 stock option plan has the authority to provide for the acceleration
of vesting of the Synopsys common shares subject to outstanding options under
the 1992 stock option plan.

     Synopsys has entered into Employment Agreements, effective October 1, 1997,
with its Chief Executive Officer and its President and an Employment Agreement
with its Chief Financial Officer, effective May 10, 2000. Each Employment
Agreement provides that if the executive is terminated involuntarily other than
for cause within 24 months of a change of control, (a) the executive will be
paid an amount equal to two times the sum of the executive's annual base pay
plus target cash incentive, plus the cash value of the executive's health
benefits for the next 18 months and (b) all stock options held by the executive
will immediately vest in full. If the executive is terminated involuntarily
other than for cause in any other situation, the executive will receive a cash
payment equal to the sum of the executive's annual base pay for one year plus
the target cash incentive for such year, plus the cash value of the executive's
health benefits for 12 months. The terms "involuntary termination," "cause" and
"change of control" are defined in each Employment Agreement, each of which is
filed with the SEC.
