Section 16(a) Beneficial Ownership Reporting Compliance

         Section 16(a) of the Exchange Act requires Synopsys' directors,
officers and greater than ten percent beneficial owners of its shares to file
reports of ownership and changes in ownership with the SEC. Directors, officers
and greater than ten percent stockholders are required by SEC regulations to
furnish Synopsys with copies of all Section 16(a) forms they file.

         Based solely upon its review of the copies of the Forms 3, 4 and 5
received by Synopsys and/or written representations from certain reporting
persons, Synopsys believes that each of its directors, officers, and greater
than ten percent beneficial owners of its shares during the fiscal year ended

persons during such fiscal year.

in Item 7 of this Annual Report.

     Employment Contracts,  Termination of Employment Arrangements and Change of
Control Agreements

         Under Synopsys' 1992 Stock Option Plan ("1992 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
sales, all outstanding options under the 1992 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 Plan has the authority to accelerate vesting of outstanding options
or shares purchased under the 1992 Plan.

         The Directors Plan provides that in the event of a change of control or
corporate transaction, as such terms are defined in the Directors Plan, all
Directors Plan options held by such director shall become fully vested and
exercisable as of the date of such change of control or corporate transaction.

         Synopsys has entered into Employment Agreements, effective October 1,
1997, with its Chief Executive Officer and its President. 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 the Employment Agreements, each of which is
filed with the SEC.
