                       --------------------------------------

                                   PROXY STATEMENT
                                         FOR
                         1998 ANNUAL MEETING OF STOCKHOLDERS

                       --------------------------------------

                                  PROCEDURAL MATTERS

GENERAL

           The enclosed Proxy is solicited on behalf of the Board of 
Directors of Summit Design, Inc., a Delaware corporation (the "Company"), for 
use at the Annual Meeting of Stockholders (the "Annual Meeting") to be held 
on Thursday, May 14, 1998 at 2:00 p.m., local time, and at any adjournment 
thereof, for the purposes set forth herein and in the accompanying Notice of 
Annual Meeting of Stockholders.  The Annual Meeting will be held at the 
Embassy Suites, 9000 S.W. Washington Square Road, Tigard, Oregon 97223.  The 
telephone number at that location is (503) 644-4000.  The Company's principal 
executive offices are located at 9305 S.W. Gemini Drive, Beaverton, Oregon 
97008.  The Company's telephone number at that location is (503) 643-9281.

           This Proxy Statement and the enclosed proxy card were mailed on or 
about April 13, 1998, together with the Company's 1997 Annual Report to 
Stockholders, to all stockholders entitled to vote at the Annual Meeting. 

RECORD DATE

           Stockholders of record at the close of business on March 27, 1998 
(the "Record Date") are entitled to notice of and to vote at the Annual 
Meeting.  As of the Record Date, 14,736,496 shares of the Company's common 
stock, $0.01 par value (the "Common Stock"), were issued and outstanding and 
entitled to be voted at the Annual Meeting.  For information regarding 
security ownership by management and by the beneficial owners of more than 5% 
of the Company's Common Stock, see "Security Ownership of Certain Beneficial 
Owners and Management." The closing price of the Company's Common Stock on 
the Nasdaq National Market on the Record Date was $14.38 per share.

REVOCABILITY OF PROXIES

           Any proxy given pursuant to this solicitation may be revoked by 
the person giving it at any time before it is voted by delivering to the 
Secretary of the Company a written notice of revocation or a duly executed 
proxy bearing a date later than that of the previously submitted proxy, or by 
attending the Annual Meeting and voting in person.

VOTING AND SOLICITATION

           Each stockholder is entitled to one vote for each share of Common 
Stock on all matters presented at the Annual Meeting.  Stockholders do not 
have the right to cumulate their votes in the election of directors.

           The cost of soliciting proxies will be borne by the Company.  The 
Company has retained the services of Skinner & Co. to assist in the 
solicitation of proxies for the Annual Meeting.  The estimated cost of such 
services is $2,500, plus reimbursement of reasonable out-of-pocket expenses.  
In addition, the Company may reimburse brokerage firms and other persons 
representing beneficial owners of Common Stock for their reasonable expenses 
in forwarding solicitation materials to such beneficial owners.  Proxies may 
also be solicited by certain of the Company's directors, officers and regular 
employees, without additional compensation, personally or by telephone, 
telegram, letter or facsimile.


<PAGE>

QUORUM; ABSTENTIONS; BROKER NON-VOTES

           The presence at the Annual Meeting, either in person or by proxy, 
of the holders of a majority of the outstanding shares of Common Stock 
entitled to vote shall constitute a quorum for the transaction of business.  
The Company intends to include abstentions and broker non-votes as present 
for purposes of establishing a quorum for the transaction of business, to 
include abstentions as shares entitled to vote and to exclude broker 
non-votes from the calculation of shares entitled to vote with respect to any 
proposal for which authorization to vote was withheld.

PROCEDURE FOR SUBMITTING STOCKHOLDER PROPOSALS

           Any proposal of a stockholder of the Company which is intended to 
be presented by such stockholder at the Company's 1999 Annual Meeting of 
Stockholders must be received by the Company no later than December 13, 1998 
in order for such proposal to be considered for inclusion in the Company's 
proxy statement and form of proxy relating to such meeting.

           In addition, the Company's Bylaws provide that stockholders 
intending to nominate candidates for election as directors or to bring 
business before an annual meeting of stockholders which were not included in 
the Company's proxy statement must deliver the prescribed notice and 
information to the Secretary of the Company not less than 60 days nor more 
than 90 days prior to the annual meeting.  However, the Bylaws also provide 
that, where less than 70 days notice or prior public disclosure of the date 
of the stockholders' meeting is given, advance notice of stockholder 
nominations for the election of directors or business to be brought before 
the annual meeting must be received not later than the close of business on 
the tenth day following the day on which such notice of the date of the 
annual meeting was mailed or such public disclosure was made. If a 
stockholder who has notified the Company of his or her intention to present a 
proposal at an annual meeting does not appear or send a qualified 
representative to present his or her proposal at such meeting, the Company 
need not present the proposal for a vote at such meeting.

                          ELECTION OF CLASS I DIRECTOR

DIRECTORS AND NOMINEE FOR CLASS I DIRECTOR

           The Company's Board of Directors currently consists of five 
members who are divided into three classes serving staggered terms.  Class I 
consists of one director, and Class II and Class III consist of two directors 
each.  The Class I director will be elected at the Annual Meeting for a term 
of three years.

           The Board of Directors has selected the nominee listed below to be 
re-elected at the Annual Meeting as the Class I director.  Unless otherwise 
instructed, the proxy holders will vote the proxies received by them for this 
nominee.  In the event that the nominee is unable or declines to serve as a 
director at the time of the Annual Meeting, the proxies will be voted for any 
nominee who shall be designated by the present Board of Directors to fill the 
vacancy; however, the Company has no reason to believe that the listed 
nominee will be unable or decline to serve as a director.  The director 
elected at this Annual Meeting will serve until the term of that director's 
class expires in 2001 or until such director's successor has been elected and 
qualified.

           The name of the nominee for Class I director and the names of each 
of the other directors of the Company whose term of office continues after 
the Annual Meeting, their ages as of March 27, 1998, and certain other 
related information are set forth below.  There are no family relationships 
between any director, executive officer or the nominee.

grants under the Company's 1996 Director Option Plan (the "Director Plan"), 
under which 150,000 shares of Common Stock have been reserved for issuance.  
The Director Plan provides for an automatic grant of an option to purchase 


                                      -4-

<PAGE>


10,000 shares of Common Stock on the date on which a person first becomes a 
non-employee director.  Thereafter, he or she will automatically be granted 
an additional option to purchase 10,000 shares on the date of the annual 
meeting of each subsequent year, provided he or she is then a non-employee 
director and provided further, that on such date he or she has served on the 
Board for at least six months.  The first option granted to a director 
pursuant to the Director Plan vests twelve months after the date of grant, 
except for Mr. Erwin's which vests one business day prior to the Company's 
first annual meeting after the grant date.  All subsequent options vest and 
become exercisable on the earlier of (i) 12 months after the date of the 
grant or (ii) one business day prior to the date of the Company's first 
annual meeting after the grant date.  Vesting of the options is subject to 
the optionee continuing to serve as a director on the vesting date.  Mr. 
Ben-David, Mr. Botts, Mr. Erwin and Dr. Karmel were each granted 10,000 
options in May 1997 at an exercise price of $9.125 per share. Mr. Ben-David, 
Mr. Botts, Dr. Karmel and Mr. Erwin, subject to his re-election, are eligible 
to receive future option grants pursuant to the Director Plan.

REQUIRED VOTE

           The nominee for Class I director receiving the highest number of 
affirmative votes of the shares entitled to be voted shall be elected to the 
Board of Directors.  Votes withheld are counted for purposes of determining 
the presence or absence of a quorum for the transaction of business, but they 
otherwise have no legal effect under Delaware law.

                                    PROPOSAL NO. 2
                             AMENDMENT TO 1994 STOCK PLAN

GENERAL

           The Company's 1994 Stock Plan was adopted by the Board of 
Directors and approved by the Company's stockholders in January 1994 and 
provides for the granting to employees (including officers and employee 
directors) of the Company of incentive stock options within the meaning of 
Section 422 of the Internal Revenue Code of 1986, as amended (the "Code") and 
for the granting to employees and consultants of the Company of nonstatutory 
stock options.  A total of 2,322,000 shares of Common Stock has been reserved 
for issuance under the 1994 Stock Plan and, as of March 27, 1998, a total of 
36,904 shares remained available for future grant.

           In 1993, Section 162(m) was added to the Code.  Section 162(m) may 
limit the Company's ability to deduct for United States federal income tax 
purposes compensation in excess of $1,000,000 paid to the Company's Chief 
Executive Officer and its four other highest paid executive officers in any 
one fiscal year.  Grants under the 1994 Stock Plan will not be subject to the 
deduction limit if the stockholders approve the material terms of the 1994 
Stock Plan, including the option grant limitations described below, for the 
purposes of Section 162(m) of the Code.

PROPOSAL

           In March 1998, the Board of Directors adopted, subject to 
stockholder approval, an amendment to the 1994 Stock Plan to increase the 
number of shares reserved for issuance by an additional 500,000 shares of 
Common Stock, for an aggregate of 2,822,000 shares reserved for issuance 
thereunder.  This amendment will enable the Company to continue to grant 
options to eligible employees and consultants under the terms and conditions 
of the 1994 Stock Plan. 

           The Board of Directors is also seeking stockholder approval of the 
material terms of the 1994 Stock Plan, including, but not limited to, the 
share limitations for purposes of Section 162(m) of the Code only.

           The Board of Directors believes that the approval of the amendment 
to the 1994 Stock Plan and the material terms of the 1994 Stock Plan for 
purposes of Section 162(m) of the Code is in the best interests of the 
Company and its stockholders, as the availability of an adequate number of 
shares for issuance under the 1994 Stock Plan and the ability to grant stock 
options are important factors in attracting, motivating and retaining 
qualified personnel essential to the success of the Company, as is the 
ability of the Company to deduct compensation.  

REQUIRED VOTE

           The affirmative vote by the holders of a majority of the Common 
Stock present in person or represented by proxy and entitled to vote on the 
subject matter is required to approve (i) the amendment to the 1994 Stock 
Plan and (ii) the material terms of the 1994 Stock Plan for the purposes of 
Section 162(m) of the Code only.  

- -------------------------------------------------------------------------------

RECOMMENDATION: THE BOARD OF DIRECTORS RECOMMENDS THAT THE STOCKHOLDERS VOTE
"FOR" THE AMENDMENT TO THE 1994 STOCK PLAN AND APPROVAL OF THE MATERIAL TERMS OF
THE 1994 STOCK PLAN.

- -------------------------------------------------------------------------------

"Administrator"), which committee is required to be constituted to comply 
with Section 16(b) of the 


                                      -6-

<PAGE>


Securities Exchange Act of 1934, as amended (the "Exchange Act"), and 
applicable laws.  Subject to the other provisions of the 1994 Stock Plan, the 
Administrator has the power to determine the employees and consultants to 
whom options may be granted, the number of shares subject to the option and 
the exercisability thereof. The Administrator also has the power to reprice 
options if the exercise price of outstanding options exceeds the fair market 
value of the Company's Common Stock.

           ELIGIBILITY; LIMITATIONS.  The 1994 Stock Plan provides that 
nonstatutory stock options may be granted to employees and consultants. 
Incentive stock options may be granted only to employees. An optionee who has 
been granted an option may, if he or she is otherwise eligible, be granted 
additional options.
 
           Section 162(m) of the Code limits the deductibility of 
compensation paid to certain executive officers of the Company.  To maximize 
the Company's deduction attributable to options granted to such persons, the 
1994 Stock Plan provides that no employee may be granted, in any fiscal year, 
options to purchase more than 500,000 shares of Common Stock.
 
           TERMS AND CONDITIONS OF OPTIONS.  Each option granted under the 
1994 Stock Plan is evidenced by a written stock option agreement between the 
optionee and the Company and is subject to the following terms and conditions:
 
                (a)  Exercise Price.  The Administrator determines the 
exercise price of options to purchase shares of Common Stock at the time the 
options are granted. However, the exercise price of an incentive stock option 
must not be less than 100% (110% if issued to any person possessing more than 
10% of the voting power of all classes of stock of the Company (a "10% 
Stockholder")) of the fair market value of the Common Stock on the date the 
option is granted. For so long as the Company's Common Stock is traded on the 
Nasdaq National Market, the fair market value of a share of Common Stock will 
be the closing sales price for such stock (or the closing bid if no sales 
were reported) on the last trading day prior to the date of grant as quoted 
on such system.
 
                (b)  Exercise of the Option.  Each stock option agreement 
will specify the term of the option and the date when the option is to become 
exercisable. The terms of such vesting are to be determined by the 
Administrator. Options granted under the 1994 Stock Plan to date generally 
become exercisable over four years at a rate of one-fourth of the shares 
subject to the options at the end of one year from the date of grant and 
1/48th at the end of each month thereafter and have a ten-year term. The 
maximum term of an option granted to a 10% Stockholder is five years. An 
option is exercised by giving written notice of exercise to the Company, 
specifying the number of full shares of Common Stock to be purchased and by 
tendering full payment of the purchase price to the Company.
 
                (c)  Form of Consideration.  The consideration to be paid for 
the shares of Common Stock issued upon exercise of an option shall be 
determined by the Administrator and is set forth in the stock option 
agreement. Such form of consideration may vary for each option, and may 
consist entirely of cash, check, promissory note, other shares of the 
Company's Common Stock, any combination thereof, or any other legally 
permissible form of consideration as may be provided in the stock option 
agreement.

                (d)  Termination of Employment.   In the event an optionee's 
continuous status as an employee or consultant terminates for any reason 
(other than upon the optionee's death or disability), the optionee may 
exercise his or her option within such period of time as is specified in such 
optionee's stock option agreement but only to the extent that the optionee 
was entitled to exercise the option at the date of such termination (but in 
no event later than the expiration of the term of such option as set forth in 
the stock option agreement).  Options granted under the 1994 Stock Plan to 
date have generally provided that optionees may exercise their options within 
sixty days from the date of termination of employment (other than for death 
or disability).

                (e)  Disability.  In the event an optionee's continuous 
status as an employee or consultant terminates as a result of permanent and 
total disability (as defined in Section 22(e)(3) of the Code), the optionee 
may exercise his or her option, but only within twelve months from the date 
of such termination, and only to the extent that the optionee was entitled 
to exercise it at the date of such termination (but in no event later than 
the expiration of the term of such option as set forth in the stock option 
agreement).

                (f)  Death.  In the event of an optionee's death, the 
optionee's estate or a person who acquired the right to exercise the deceased 
optionee's option by bequest or inheritance may exercise the option, but only 
within twelve months


                                       -7-
<PAGE>

following the date of death, and only to the extent that the optionee was 
entitled to exercise it at the date of death (but in no event later than the 
expiration of the term of such option as set forth in the stock option 
agreement).

                (g)  Term of Options.  The term of each option is the term 
stated in the stock option agreement; provided, however, that the term may 
not exceed ten years from the date of grant. In the case of an incentive 
stock option granted to a 10% Stockholder, the term may not exceed five years 
from the date of grant. No option may be exercised by any person after the 
expiration of its term.

                (h)  Nontransferability of Options.  An option is 
nontransferable by the optionee, other than by will or the laws of descent 
and distribution, and is exercisable during the optionee's lifetime only by 
the optionee. In the event of the optionee's death, options may be exercised 
by a person who acquires the right to exercise the option by bequest or 
inheritance.

                (i)  Value Limitation.  If the aggregate fair market value 
(as determined on date of grant) of all shares of Common Stock subject to an 
optionee's incentive stock option which are exercisable for the first time 
during any calendar year exceeds $100,000, the excess options shall be 
treated as nonstatutory options.

                (j)  Other Provisions.  The stock option agreement may 
contain such other terms, provisions and conditions not inconsistent with the 
1994 Stock Plan as may be determined by the Administrator.

           ADJUSTMENT UPON CHANGES IN CAPITALIZATION; CORPORATE TRANSACTIONS. 
In the event of changes in the outstanding Common Stock of the Company by 
reason of any stock splits, reverse stock splits, stock dividends, 
combinations, reclassifications or other similar change in the capital 
structure of the Company, an appropriate adjustment shall be made by the 
Administrator in the following: (i) the number of shares of Common Stock 
subject to the 1994 Stock Plan, (ii) the number and class of shares of stock 
subject to any option outstanding under the 1994 Stock Plan, (iii) and the 
exercise price of any such outstanding option. The determination of the 
Administrator as to which adjustments made shall be conclusive. In the event 
of a proposed dissolution or liquidation of the Company, the Board will 
notify the holders of options as soon as practicable prior to such action, 
and all outstanding options will terminate immediately prior to the 
consummation of such proposed action.  Notwithstanding the above, in the 
event of a merger of the Company with or into another corporation or the sale 
of substantially all of the assets of the Company, the 1994 Stock Plan 
requires that each outstanding option be assumed or an equivalent option be 
substituted by the successor corporation; provided, however, if such 
successor or purchaser refuses to assume or substitute the then outstanding 
options, the 1994 Stock Plan provides for the full acceleration of the 
exercisability of all outstanding options for a period of ten days from the 
date of notice of acceleration to the holder and all options will terminate 
upon the expiration of such period.

           AMENDMENT AND TERMINATION OF THE 1994 STOCK PLAN.  The Board may 
at any time amend, alter, suspend or terminate the 1994 Stock Plan. The 
Company shall obtain stockholder approval of any amendment to the 1994 Stock 
Plan in such a manner and to such a degree as is necessary and desirable to 
comply with Rule 16b-3 under the Exchange Act and Sections 162(m) and 422 of 
the Code (or any other applicable law or regulation, including the 
requirements of any exchange or quotation system on which the Common Stock is 
traded). Any amendment or termination of the 1994 Stock Plan shall not affect 
options already granted and such options shall remain in full force and 
effect as if the 1994 Stock Plan had not been amended or terminated, unless 
mutually agreed otherwise between the optionee and the Company, which 
agreement must be in writing and signed by the optionee and the Company. In 
any event, the 1994 Stock Plan shall terminate in May 2004. Any options 
outstanding under the 1994 Stock Plan at the time of its termination shall 
remain outstanding until they expire by their terms.


FEDERAL INCOME TAX CONSEQUENCES

           INCENTIVE STOCK OPTIONS.  An optionee who is granted an incentive 
stock option does not recognize taxable income at the time the option is 
granted or upon its exercise, although the exercise may subject the optionee 
to the alternative minimum tax.  Upon a disposition of the shares more than 
two years after grant of the option and one year after exercise of the 
option, any gain or loss is treated as long-term capital gain or loss.  If 
these holding periods are not satisfied, the optionee recognizes ordinary 
income at the time of disposition equal to the difference between the 
exercise price and the lower of (i) the fair market value of the shares at 
the date of the option exercise or (ii) the sale price of the shares.  Any 
gain or loss recognized on such a premature disposition of the shares in 
excess of the amount treated as ordinary income is treated as long-term or 
short-term capital gain or loss, depending on the holding period.  Long-term 
capital gains are grouped and netted by


                                       -8-
<PAGE>


holding periods.  Net capital gains on assets held for more than twelve 
months and up to eighteen months is currently taxed at a maximum federal rate 
of 28%. Net capital gains on assets held for more than 18 months is capped at 
20%. Capital losses are allowed in full against capital gains and up to 
$3,000 against other income. A different rule for measuring ordinary income 
upon such a premature disposition may apply if the optionee is also an 
officer, director, or 10% Stockholder of the Company.  The Company is 
entitled to a deduction in the same amount as the ordinary income recognized 
by the optionee.

           NONSTATUTORY STOCK OPTIONS.  An optionee does not recognize any 
taxable income at the time he or she is granted a nonstatutory stock option.  
Upon exercise, the optionee recognizes taxable income generally measured by 
the excess of the then fair market value of the shares over the exercise 
price.  Any taxable income recognized in connection with an option exercise 
by an employee of the Company is subject to tax withholding by the Company.  
The Company is entitled to a deduction in the same amount as the ordinary 
income recognized by the optionee.  Upon a disposition of such shares by the 
optionee, any difference between the sale price and the optionee's exercise 
price, to the extent not recognized as taxable income as provided above, is 
treated as long-term or short-term capital gain or loss, depending on the 
holding period.  Net capital gains on assets held for more than twelve months 
and up to eighteen months is currently taxed at a maximum federal rate of 
28%. Net capital gains on assets held for more than 18 months is capped at 
20%. Capital losses are allowed in full against capital gains and up to 
$3,000 against other income.  

           The purchaser may accelerate to the date of purchase his or her 
recognition of ordinary income, if any, and the beginning of any capital gain 
holding period by timely filing an election pursuant to Section 83(b) of the 
Code.  In such event, the ordinary income recognized, if any, is measured as 
the difference between the purchase price and the fair market value of the 
stock on the date of purchase, and the capital gain holding period commences 
on such date.  The ordinary income recognized by a purchaser who is an 
employee will be subject to tax withholding by the Company.  Different rules 
may apply if the purchaser is also an officer, director, or 10% Stockholder 
of the Company.

           THE FOREGOING IS ONLY A SUMMARY OF THE EFFECT OF FEDERAL INCOME 
TAXATION UPON OPTIONEES AND THE COMPANY WITH RESPECT TO THE GRANT AND 
EXERCISE OF OPTIONS UNDER THE 1994 STOCK PLAN.  IT DOES NOT PURPORT TO BE 
COMPLETE, AND DOES NOT DISCUSS THE TAX CONSEQUENCES OF THE EMPLOYEE'S OR 
CONSULTANT'S DEATH OR THE PROVISIONS OF THE INCOME TAX LAWS OF ANY 
MUNICIPALITY, STATE OR FOREIGN COUNTRY IN WHICH THE EMPLOYEE OR CONSULTANT 
MAY RESIDE.

PARTICIPATION IN THE 1994 STOCK PLAN

           The grant of options under the 1994 Stock Plan to employees, 
including the Named Executive Officers (as defined under "Executive Officer 
Compensation"), is subject to the discretion of the Administrator. As of the 
date of this proxy statement, there has been no determination by the 
Administrator with respect to future awards under the 1994 Stock Plan. 
Accordingly, future awards are not determinable. Non-employee directors are 
not eligible to participate in the 1994 Stock Plan. The following table sets 
forth information with respect to the grant of options pursuant to the 1994 
Stock Plan to the Named Executive Officers, to all current executive officers

                  ADDITIONAL INFORMATION RELATED TO PROPOSAL NO. 2

1997 NONSTATUTORY STOCK OPTION PLAN

           In December 1997, the Board of Directors adopted the 1997 
Nonstatutory Stock Option Plan.  A total of 250,000 shares of Common Stock 
has been reserved for issuance under the 1997 Nonstatutory Stock Option Plan, 
and as of March 27, 1998, a total of 15,000 shares remained eligible for 
future grant.   The 1997 Nonstatutory Stock Option Plan provides for grants 
to employees, directors and consultants of the Company; however, no greater 
than 25,000 options may be granted to directors and executive officers of the 
Company.  In December 1997, Mr. Guy, a Named Executive Officer of the 
Company, received an option grant exercisable for 25,000 shares of the 
Company's Common Stock at an exercise price of $9.63 per share pursuant to 
the 1997 Nonstatutory Stock Option Plan.

                                    PROPOSAL NO. 3
                    AMENDMENT TO 1996 EMPLOYEE STOCK PURCHASE PLAN

GENERAL

           The 1996 Employee Stock Purchase Plan was adopted by the Board of 
Directors and approved by the Company's stockholders in October 1996.  The 
1996 Employee Stock Purchase Plan, which is intended to qualify under Section 
423 of the Code, permits eligible employees to purchase the Company's Common 
Stock through payroll deductions at a price equal to 85% of the lower of the 
fair market value of the Common Stock on the first day of each 24-month 
offering period or the last day of the applicable six-month purchase period.  
The Company has reserved a total of 150,000 shares of Common Stock for 
issuance under the 1996 Employee Stock Purchase Plan, and as of March 27, 
1998, 91,299 shares remained available for future issuances.

PROPOSAL

           In March 1998, the Board of Directors adopted, subject to 
stockholder approval, an amendment to the 1996 Employee Stock Purchase Plan 
to increase the number of shares reserved for issuance by an additional 
235,000 shares of Common Stock, for an aggregate of 385,000 shares reserved 
for issuance thereunder. This amendment will enable the Company to continue 
to grant purchase rights to eligible employees under the terms and conditions 
of the 1996 Employee Stock Purchase Plan.

           The Board of Directors believes that the approval of the amendment 
to the 1996 Employee Stock Purchase Plan is in the best interests of the 
Company and its stockholders, as the availability of an adequate number of 
shares for issuance under the 1996 Employee Stock Purchase Plan and the 
ability of employees to participate in the 1996 Employee Stock Purchase Plan 
are important factors in attracting, motivating and retaining qualified 
personnel essential to the success of the Company.

REQUIRED VOTE

           The affirmative vote by the holders of a majority of the Common 
Stock present in person or represented by proxy and entitled to vote on the 
subject matter is required to approve the amendment to the 1996 Employee 
Stock Purchase Plan.

- -------------------------------------------------------------------------------

RECOMMENDATION: THE BOARD OF DIRECTORS RECOMMENDS THAT THE STOCKHOLDERS VOTE
"FOR" THE AMENDMENT TO THE 1996 EMPLOYEE STOCK PURCHASE PLAN.

- -------------------------------------------------------------------------------

SUMMARY OF THE 1996 EMPLOYEE STOCK PURCHASE PLAN

            The following summary of the 1996 Employee Stock Purchase Plan is 
qualified in its entirety by the specific language of the 1996 Employee Stock 
Purchase Plan, a copy of which is available to any stockholder upon written 
request to the Secretary of the Company.

           PURPOSE.  The purposes of the 1996 Employee Stock Purchase Plan 
are to attract and retain the best available personnel for positions of 
substantial responsibility, to provide additional incentive to employees of 
the Company and to promote the success of the Company's business.

           ADMINISTRATION.  The 1996 Employee Stock Purchase Plan may be 
administered by the Board of Directors or a committee of the Board of 
Directors (the "Administrator"), which committee is required to be 
constituted to comply with Section 16(b) of the Exchange Act, and applicable 
laws. 

           ELIGIBILITY; LIMITATIONS.  The 1996 Employee Stock Purchase Plan 
provides that employees are eligible to participate if they are customarily 
employed by the Company or any designated subsidiary for at least 20 hours 
per week and for more than five months in any calendar year.


                                       -11-

<PAGE>
           TERMS AND CONDITIONS OF SUBSCRIPTION.  Participation under the 
1996 Employee Stock Purchase Plan is evidenced by a written subscription 
agreement between the employee and the Company and is subject to the 
following terms and conditions of the 1996 Employee Stock Purchase Plan:

                (a) Purchase Price and Method.  Employees who participate in 
the 1996 Employee Stock Purchase Plan purchase the Company's Common Stock 
through payroll deductions of up to 10% of their base salary, up to a maximum 
number of shares per purchase period determined by dividing $12,500 by the 
fair market value of a share of Common Stock on the first day of the offering 
period of $25,000 of Common Stock (determined as of the first day of an 
offering period) for all purchase periods ending within any calendar year.  
The price of Common Stock purchased under the 1996 Employee Stock Purchase 
Plan is 85% of the lower of the fair market value of the Common Stock on the 
first day of each 24-month offering period and the last day of the applicable 
six-month purchase period. To the extent the fair market value of the Common 
Stock on any exercise date in an offering period is lower than the fair 
market value of the Common Stock on the first day of the offering period, 
then all participants in such offering period will be automatically withdrawn 
from such offering period immediately after the exercise of their options on 
such exercise date and automatically re-enrolled in the immediately following 
offering period as of the first day thereof.

                (b) Offering Periods.  Offering periods last 24 months and 
commence on the first trading day on or after May 1 and November 1 of each 
year and terminate on the last trading day in the periods ending 24 months 
later.  Each 24-month offering period consists of four purchase periods of 
approximately six months duration.  The first offering period, however, 
commenced on October 18, 1996, the date on which the Company's registration 
statement on Form S-1 was declared effective, and will end on the last 
trading day on or before October 31, 1998.

                (c) Withdrawal; Termination of Employment.  If an employee 
decides to terminate his or her participation in the 1996 Employee Stock 
Purchase Plan, he or she must withdraw all the payroll deductions credited to 
his or her purchase account, and such funds will be returned to him or her.  
Upon the termination of employment for any reason, all payroll deductions 
will likewise be returned to the (former) employee. 

                (d) Death.  A participating employee may designate who is to 
receive any shares and cash, if any, from the participant's account under the 
1996 Employee Stock Purchase Plan in the event of such participant's death 
subsequent to exercising a purchase option but prior to delivery of the share 
of Common Stock. 

                (e) Nontransferability.  Rights granted under the 1996 
Employee Stock Purchase Plan are not transferable by a participant other than 
by will, the laws of descent and distribution, or as otherwise provided under 
the plan, and the Company may treat any prohibited attempt to transfer as an 
election to withdraw. 

                (f) Other Provisions.  The subscription agreement may contain 
such other terms, provisions and conditions not inconsistent with the 1996 
Employee Stock Purchase Plan as may be determined by the Administrator.

           ADJUSTMENT UPON CHANGES IN CAPITALIZATION; CORPORATE TRANSACTIONS. 
In the event of changes in the outstanding Common Stock of the Company by 
reason of any stock splits, reverse stock splits, stock dividends, 
combinations, reclassifications or other similar change in the capital 
structure of the Company, an appropriate adjustment shall be made by the 
Administrator in the following: (i) the number of shares of Common Stock 
subject to the 1996 Employee Stock Purchase Plan and (ii) the number and 
class of shares of stock subject to any purchase right outstanding under the 
1996 Employee Stock Purchase Plan.  The determination of the Administrator as 
to which adjustments shall be made shall be conclusive. In the event of a 
proposed dissolution or liquidation of the Company, the offering periods 
shall terminate immediately prior to the consummation of such proposed 
action, unless otherwise provided by the Company's Board of Directors. 
Notwithstanding the above, in the event of a merger of the Company with or 
into another corporation or the sale of substantially all of the assets of 
the Company, any purchase period then in progress shall be shortened by 
setting a new exercise date and any offering period then in progress shall 
end on the new exercise date. 

           AMENDMENT AND TERMINATION OF THE 1996 EMPLOYEE STOCK PURCHASE 
PLAN.  The Board may at any time amend, alter, suspend or terminate the 1996 
Employee Stock Purchase Plan. The Company shall obtain stockholder approval 
of any amendment to the 1996 Employee Stock Purchase Plan in such a manner 
and to such a degree as is necessary and desirable to comply with Rule 16b-3 
under the Exchange Act and 423 of the Code (or any other applicable law or 
regulation, including the requirements of any exchange or quotation system on 
which the Common Stock is traded). Any amendment or termination

                                      -12-
<PAGE>


of the 1996 Employee Stock Purchase Plan shall not affect options already 
granted and such options shall remain in full force and effect as if the 1996 
Employee Stock Purchase Plan had not been amended or terminated, unless 
mutually agreed otherwise between the optionee and the Company, which 
agreement must be in writing and signed by the participant and the Company.  
In any event, the 1996 Employee Stock Purchase Plan shall terminate in 
October 2006.

FEDERAL INCOME TAX CONSEQUENCES

           No income will be taxable to a participant until the shares 
purchased under the 1996 Employee Stock Purchase Plan are sold or otherwise 
disposed of.  Upon sale or other disposition of the shares, the participant 
will generally be subject to tax and the amount of the tax will depend upon 
the holding period. If the shares are sold or otherwise disposed of more than 
two (2) years from the first day of the offering period or more than one (1) 
year from the date of transfer of the stock to the participant (the 
"Statutory Holding Periods"), then the participant will recognize ordinary 
income measured as the lesser of (i) the excess of the fair market value of 
the shares at the time of such sale or disposition over the purchase price, 
or (ii) an amount equal to 15% of the fair market value of the shares as of 
the first day of the offering period.  Any additional gain will be treated as 
long-term capital gain.  Net capital gains on assets held for more than 
twelve months and up to eighteen months are currently taxed at a maximum 
federal rate of 28%. Net capital gains on assets held for more than 18 months 
are capped at 20%. Capital losses are allowed in full against capital gains 
and up to $3,000 against other income.  If the shares are sold or otherwise 
disposed of before the expiration of the Statutory Holding Periods, the 
participant will recognize ordinary income generally measured as the excess 
of the fair market value of the shares on the date the shares are purchased 
over the purchase price.  Any additional gain or loss on such sale or 
disposition will be long-term or short-term capital gain or loss, depending 
on the holding periods.  The Company is not entitled to a deduction for 
amounts taxed as ordinary income or capital gain to a participant except to 
the extent of ordinary income is recognized by participants upon a sale or 
disposition of shares prior to the expiration of the Statutory Holding 
Periods described above.

           THE FOREGOING IS ONLY A SUMMARY OF THE EFFECT OF FEDERAL INCOME 
TAXATION UPON THE PARTICIPANT AND THE COMPANY WITH RESPECT TO THE SHARES 
PURCHASED UNDER THE PURCHASE PLAN.  REFERENCE SHOULD BE MADE TO THE 
APPLICABLE PROVISIONS OF THE CODE.  IN ADDITION, THE SUMMARY DOES NOT DISCUSS 
THE TAX CONSEQUENCES OF A PARTICIPANT'S DEATH OR THE INCOME TAX LAWS OF ANY 
STATE OR FOREIGN COUNTRY IN WHICH THE PARTICIPANT MAY RESIDE.

Mr. Gerhard was also granted options to purchase up to 75,000 shares of 
Common Stock, subject to vesting over a three-year period.  In addition, Mr. 
Gerhard is entitled to an allowance for car expenses of $1,000 per month.  In 
the event Mr. Gerhard is terminated other than for cause, he is entitled to 
severance of $33,333.33 per month plus all insurance benefits until he 
accepts other full time employment, but in no event for longer than 
twenty-four months. This agreement will be automatically extended for 
additional one-year terms unless terminated by either party with 90 days 
written notice prior to the end of the then current term.   

           On October 21, 1995, the Company entered into a four-year 
employment agreement with Mr. Koob pursuant to which he receives an annual 
base salary, an annual bonus of up to 25% of his base salary, all standard 
benefits accorded other executives of the Company, and relocation costs.  
Under the agreement, Mr. Koob was granted options to purchase up to 75,000 
shares of Common Stock, subject to vesting over a four-year period.  Such 
options automatically vest upon termination of Mr. Koob other than for cause 
and upon the sale of more than 75% of the assets or 50% of the outstanding 
capital stock of the Company.  In addition, the agreement provided that upon 
consummation of the Company's initial public offering, the four-year vesting 
schedule with respect to such options accelerated by one year.  In the event 
Mr. Koob is terminated other than for cause, he is entitled to severance of 
$10,416.67 per month plus all insurance benefits until he accepts other full 
time employment, but in no event for longer than nine months.  In the event 
Mr. Koob resigns or is terminated for cause within 36 months after the date 
of the employment agreement, any unvested options and any options which 
vested, and shares issued upon exercise of such options, within one year 
prior to such resignation or termination may be repurchased by the Company at 
the option exercise price.  This agreement will be automatically extended for 
additional one-year terms unless terminated by either party with 90 days 
written notice prior to the end of the then current term.

agreement with Mr. Guy, pursuant to which he receives an annual base salary, 
an annual bonus of up to 25% of his base salary, and all standard benefits

time employment, but in no event for 

                                       -20-

longer than twelve  months. This agreement will be automatically extended for 
additional one-year terms unless terminated by either party with 90 days 
written notice prior to the end of the then current term.

agreement with Mr. DiFerdinando, pursuant to which he received an annual base 
salary, an annual bonus of up to 25% of his base salary, and all standard 
benefits accorded other executives of the Company.  Under the agreement, Mr. 
DiFerdinando was granted options to purchase up to 25,000 shares of Common 
Stock, subject to vesting over a four-year period, unless the Company sold 
substantially all of its assets or was acquired, in which case all shares 
would have vested immediately.  In the event Mr. DiFerdinando was terminated 
other than for cause, he would have been entitled to severance equal to his 
then monthly base salary plus all current insurance benefits until he 
accepted other full time employment, but in no event for longer than six 
months.  Mr. DiFerdinando also received relocation expense reimbursement as 
well as an equity protection over the sale price of his home.  Mr. 
DiFerdinando terminated his employment with the Company in January 1998. 

           Effective October 31, 1994, the Company entered into a four-year 
employment agreement with Mr. Benhayoun pursuant to which he receives an 
annual base salary, commissions based on sales revenue generated, and all 
standard benefits accorded other executives of the Company.  Under the 
employment agreement, Mr. Benhayoun was granted options to purchase up to 
58,500 shares of Common Stock, of which 15,000 vested immediately, 15,000 
vested on October 31, 1995, and the remainder vested ratably over the 24 
months following October 31, 1995. In addition, the agreement provided that 
upon consummation of the Company's initial public offering, the two-year 
vesting schedule with respect to such options accelerated by one year.  In 
addition, in the event Mr. Benhayoun is terminated other than for cause, he 
is entitled to severance of 52,083 French francs (approximately $8,502.65 as 
of March 27, 1998) per month plus all insurance benefits until he accepts 
other full-time employment, but in no event longer than nine months. 

                                 CERTAIN TRANSACTIONS

           In December 1993, the Company's Israeli subsidiary, Summit Design 
(EDA) Ltd. (formerly named SEE Technologies), entered into a four-year 
sublease pursuant to which Summit Design (EDA) Ltd. subleases space for its 
corporate offices from DCL Holding & Investment in Technology (1993), Ltd. 
("DCL") on terms and conditions similar to those under which DCL leases such 
office space from the third-party owner of the office space.  DCL is a 5% 
stockholder of the Company and wholly-owned subsidiary of DCL Technologies 
Ltd.  Amihai Ben-David, a director of the Company, is the Chief Executive 
Officer and Chairman of DCL Technologies Ltd.  The Company believes that the 
terms of the foregoing lease are no less favorable to the Company than those 
that could have been obtained from unaffiliated third parties.

           In May 1997, the Company loaned $350,000 to Moshe Guy, an 
executive officer of the Company, for the purchase of a primary residence 
pursuant to a promissory note that bore interest at the rate of 5% per year.  
The principal and accrued interest were repaid in September 1997.

           In July 1997, the Company loaned an aggregate of $165,000 to John 
DiFerdinando for the purchase of a primary residence pursuant to two 
promissory notes that bore interest at the rate of 5.98% per year.  The 
principal and accrued interest were repaid in October 1997.  Mr. 
DiFerdinando, formerly an executive officer of the Company, terminated his 
employment with the Company in January 1998.  

           In September 1997, the Company repurchased 24,000 and 150,000 
shares of the Company's Common Stock at a price of $12.56 per share from C. 
Albert Koob and L&K Properties Limited Partnership, respectively.  Mr. Koob 
is an executive officer of the Company, and Larry Gerhard, the sole general 
partner and a limited partner of L&K Properties Limited Partnership, is an 
executive officer and director of the Company.   The Company also repurchased 
200,000 shares from DCL.

executive officer of the Company, received $2,202,731 and 692,089 shares of 
the Company's Common Stock in exchange for his shares of SimTech stock.  Part 
of those shares are subject to a lock-up arrangement and held in escrow.  The 
shares will be released from the lock-up over a 24-month period subject to 
Mr. Davenport's continued employment with the Company.  The Richard Davenport 
1997 Irrevocable Annuity Trust also received $362,153 and 113,786 shares of

           The Company has a line of credit for $1,000,000 with the United 
States National Bank of Oregon, a subsidiary of U.S. Bancorp.  Steven P. 
Erwin, a nominee for director of the Company, was Executive Vice President 
and Chief Financial Officer of U.S. Bancorp until July 1997.

               SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

           Section 16(a) of the Securities Exchange Act of 1934 requires the 
Company's executive officers and directors, and persons who own more than 10% 
of a registered class of the Company's equity securities to file reports of 
ownership and changes in ownership with the Securities and Exchange 
Commission ("SEC"). Executive officers, directors and greater than 10% 
stockholders are required by SEC rules to furnish the Company with copies of 
all forms they file.  Based solely on its review of the copies of such forms 
received by the Company and written representations from certain reporting 
persons, the Company believes that, during 1997, all Section 16(a) filing 
requirements applicable to its executive officers, directors and 10% 
stockholders were satisfied, except that the Form 3 for Richard Davenport and 
the Form 4's for DCL Technologies Ltd. for September 1997 and November 1997 
were filed late.

             COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

           The Compensation Committee was formed in August 1994 and is 
currently composed of Messrs. Ben-David and Botts.   No interlocking 
relationship exists between any member of the Company's Compensation 
Committee and any member of any other company's board of directors or 
compensation committee.

                                CHANGES IN ACCOUNTANTS

           On February 9, 1996, Coopers & Lybrand L.L.P. was engaged as the 
principal independent accountants for the Company and its subsidiaries, 
replacing KPMG Peat Marwick LLP ("KPMG"), which was dismissed in January 
1996.  The change was approved by the Audit Committee of the Company's Board 
of Directors.  In connection with the audits of the year ended December 31, 
1995 and through the interim period ended February 8, 1996, there were no 
disagreements with KPMG on any matter of accounting principles or practices, 
financial statement disclosure, or auditing scope or procedures, which 
disagreements, if not resolved to KPMG's satisfaction, would have caused them 
to make reference to the matter in their report.  The audit reports of KPMG 
on the consolidated financial statements of the Company as of and for the 
year ended December 31, 1994 did not contain any adverse opinion or 
disclaimer of opinion, nor were they qualified or modified as to uncertainty 
or audit scope.  The audit report for the year ended December 31, 1994 was 
modified to include a discussion on the restatement of the Company's 1993 
financial statements for the timing of when certain expenses were recognized 
in the financial statements.  During the audit period ended December 31, 
1994, and through the interim period ended January 31, 1996 there have been 
no reportable events.

           During the two fiscal years ended December 31, 1996, and through 
the interim period ended February 8, 1996, the Company had not consulted with 
Coopers & Lybrand L.L.P. on items which concerned the subject matter of a 
disagreement or reportable event with the former auditor.

            REPORT OF THE COMPENSATION COMMITTEE OF THE BOARD OF DIRECTORS

           The Compensation Committee of the Board of Directors (the 
"Committee") was established in August 1994 and is responsible for reviewing 
the compensation and benefits for the Company's executive officers, as well 
as supervising and making recommendations to the Board on compensation 
matters generally.  The Committee also administers the Company's stock plans.

COMPENSATION PHILOSOPHY AND POLICY

           The policy of the Committee is to attract and retain executive 
officers and employees through the payment of competitive base salaries and 
to encourage and reward performance through bonuses and stock ownership.  The 
objectives of the Committee are to:

           -  attract, retain and motivate highly qualified executive 
              officers and employees who contribute to the long-term success 
              of the Company;

           -  align the compensation of executive officers with business 
              objectives and performance; and

           -  align incentives for executive officers with the interests of 
              stockholders in maximizing value.

           The Company has taken the necessary steps to conform its 
compensation practices to comply with the $1 million compensation deduction 
cap under Section 162(m) of the Internal Revenue Code, as amended.

ELEMENTS OF COMPENSATION

           Compensation for executive officers includes both cash and equity 
elements.

           Cash compensation consists of (i) base salary which is determined 
on the basis of the level of responsibility, expertise and experience of the 
executive officer, taking into account competitive conditions in the industry 
and (ii) cash bonuses up to an established percentage of base salary, subject 
to meeting all or a portion of targeted objectives.

           Ownership of the Company's Common Stock is a key element of 
executive compensation.  Executive officers and other employees of the 
Company are eligible to participate in the 1994 Stock Plan (the "Option 
Plan") and the 1996 Employee Stock Purchase Plan (the "Purchase Plan").  The 
Option Plan permits the Board of Directors or the Committee to grant stock 
options to employees on such terms as the Board or the Committee may 
determine.  The Committee has the sole authority to grant stock options to 
executive officers of the Company and is currently administering stock option 
grants to all employees.  In determining the size of a stock option grant to 
a new executive officer or other employee, the Committee takes into account 
equity participation by comparable employees within the Company, external 
competitive circumstances and other relevant factors.  Additional options may 
be granted to current executive officers and employees to reward exceptional 
performance or to provide additional unvested equity incentives.  These 
options typically vest over a four-year period and thus require the 
employee's continuing service to the Company.  The Purchase Plan permits 
employees to acquire Common Stock of the Company through payroll deductions 
and promotes broad-based equity participation throughout the Company. The 
Committee believes that such stock plans align the interests of the employees 
with the long-term interests of the stockholders.

           The Company also maintains a 401(k) Plan to provide retirement 
benefits through tax deferred salary deductions for all its employees.  In 
1997, the Company contributed to the 401(k) Plan by partially matching 
employees' contribution at a one-to-four ratio; provided, however, that the 
Company's matching contribution for any employee could not exceed 1.5% of 
such employee's salary.

1997 EXECUTIVE COMPENSATION

           Executive compensation for fiscal 1997 included base salary and 
cash bonuses based upon achievement of corporate goals and individual 
performance goals.  Executive officers, like other employees, were eligible 
for option grants under the Option Plan and to participate in the Purchase 
Plan.

CHIEF EXECUTIVE OFFICER COMPENSATION FOR 1997

           Mr. Gerhard's compensation package is set forth in an employment 
agreement that was approved by the Committee and took effect in August 1997, 
replacing his then existing employment agreement.  In 1997, Mr. Gerhard 
received a salary of $341,667 and a bonus of $160,000.  Mr. Gerhard's bonus 
for 1997 consisted of $100,000 pursuant to his employment agreement for the 
achievement of the corporate revenue goal set for 1997 and an additional 
$60,000 for the Company's performance in 1997.  Mr. Gerhard was also granted 
an option to purchase 75,000 shares of the Company's Common Stock.

discretionary plan, or (B) a Committee designated by the Board to administer 
the Plan, which Committee shall be constituted in such a manner as to permit 
the Plan to comply with Rule 16b-3 with respect to a plan intended to qualify 
thereunder as a discretionary plan. Once appointed, such Committee shall 
continue to serve in its designated capacity until otherwise directed by the 
Board.  From time to time the Board may increase the size of the Committee 
and appoint additional members thereof, remove members (with or without 
cause) and appoint new members in substitution therefor, fill vacancies, 
however caused, and remove all members of the Committee and thereafter 
directly administer the Plan, all to the extent permitted by Rule 16b-3 with 
respect to a plan intended to qualify thereunder as a discretionary plan.

                            (ii)   MULTIPLE ADMINISTRATIVE BODIES.  If permitted
by Rule 16b-3, the Plan may be administered by different bodies with respect to

the legal requirements relating to the administration of incentive stock 
option plans, if any, of applicable state corporate and securities laws, of 
the Code, and of any applicable stock exchange (including Nasdaq) (the 
"Applicable Laws"). Once appointed, such Committee shall continue to serve in 
its designated capacity until otherwise directed by the Board.  From time to 
time the Board may increase the size of the Committee and appoint additional 
members thereof, remove members (with or without cause) and appoint new 
members in substitution therefor, fill vacancies, however caused, and remove 
all members of the Committee and thereafter directly administer the Plan, all 
to the extent permitted by the Applicable Laws.

              (b)    POWERS OF THE ADMINISTRATOR.  Subject to the provisions of
the Plan and, in the case of a Committee, the specific duties delegated by the
Board to such Committee, and subject to the approval of any relevant
authorities, including the approval, if required, of any stock exchange upon
which the Common Stock is listed, the Administrator shall have the authority, in
its discretion:

                            (i)    to determine the Fair Market Value of the
Common Stock, in accordance with Section 2(l) of the Plan;

                           (iii)  to determine whether and to what extent
Options or any combination thereof are granted hereunder;

                            (iv)   to determine the number of shares of Common
Stock to be covered by each such award granted hereunder;

                             (v)    to approve forms of agreements for use under
the Plan, which forms may differ with respect to individual Optionees;

                            (vi)   to determine the terms and conditions, not
inconsistent with the terms of the Plan, of any award granted hereunder,
including the terms of any right of first refusal of the Company to purchase
Shares granted pursuant to the Plan and the terms of any repurchase option of
the Company with respect to unvested Shares;

                           (vii)  with respect to any Option, to determine
whether and under what circumstances an Option may be settled in cash under
subsection 9(f) instead of Common Stock;

                          (viii) to reduce the exercise price of the Option to
the then current Fair Market Value if the Fair Market Value of the Common Stock
covered by such Option shall have declined since the date the Option was
granted; and

                            (ix)   to construe and interpret the terms of the
Plan and awards granted pursuant to the Plan.

              (c)    EFFECT OF ADMINISTRATOR'S DECISION.  All decisions,
determinations and interpretations of the Administrator shall be final and
binding on all Optionees and any other holders of any Options.

       5.     ELIGIBILITY.

              (a)    Nonstatutory Stock Options may be granted to Employees and
Consultants.  Incentive Stock Options may be granted only to Employees.  An
Employee or Consultant who has been granted an Option may, if otherwise
eligible, be granted additional Options.

              (b)    Each Option shall be designated in the written option
agreement as either an Incentive Stock Option or a Nonstatutory Stock Option. 
However, notwithstanding such designations, to the extent that the aggregate
Fair Market Value of the Shares with respect to which Options designated as
Incentive Stock Options are exercisable for the first time by any Optionee
during any calendar year (under all plans of the Company or any Parent or
Subsidiary, including Options granted in substitution of options granted under
the TSSI Plan) exceeds $100,000, such excess Options shall be treated as
Nonstatutory Stock Options.

                                    -5-

<PAGE>

              (c)    For purposes of Section 5(b), Incentive Stock Options shall
be taken into account in the order in which they were granted, and the Fair
Market Value of the Shares shall be determined as of the time the Option with
respect to such Shares is granted.

              (d)    The Plan shall not confer upon any Optionee any right with
respect to continuation of employment relationship with the Company, nor shall
it interfere in any way with his or her right or the Company's right to
terminate his or her employment relationship at any time, with or without cause.

              (e)    The following limitations shall apply to grants of Options
to Employees:

                            (i)    No Employee shall be granted, in any fiscal
year of the Company, Options to purchase more than 500,000 Shares.

                           (ii)   The foregoing limitation shall be adjusted
proportionately in connection with any change in the Company's capitalization as
described in Section 11(a). 

                          (iii)  If an Option is canceled in the same fiscal
year of the Company in which it was granted (other than in connection with a
transaction described in Section 11), the canceled Option shall be counted
against the limit set forth in Section 5(e)(i).  For this purpose, if the
exercise price of an Option is reduced, the transaction shall be treated as a
cancellation of the Option and the grant of a new Option.

       6.     TERM OF PLAN.  The Plan shall become effective upon the earlier to
occur of its adoption by the Board of Directors or its approval by the
stockholders of the Company, as described in Section 17 of the Plan.  It shall
continue in effect for a term of ten (10) years unless sooner terminated under
Section 13 of the Plan.

       7.     TERM OF OPTION.  The term of each Option shall be the term stated
in the Option Agreement; provided, however, that the term shall be no more than
ten (10) years from the date of grant thereof.  However, in the case of an
Incentive Stock Option granted to an Optionee who, at the time the Option is
granted, owns stock representing more than ten percent (10%) of the voting power
of all classes of stock of the Company or any Parent or Subsidiary, the term of
the Option shall be five (5) years from the date of grant thereof or such
shorter term as may be provided in the Option Agreement.

       8.     OPTION EXERCISE PRICE AND CONSIDERATION.

              (a)    The per share exercise price for the Shares to be issued
pursuant to exercise of an Option shall be such price as is determined by the
Committee, but shall be subject to the following:

                            (i)    In the case of an Incentive Stock Option

                                   (A)    granted to an Employee who, at the
time of the grant of such Incentive Stock Option, owns stock representing more
than ten percent (10%) of the voting power of all classes of stock of the
Company or any Parent or Subsidiary, the per Share exercise price shall be no
less than 110% of the Fair Market Value per Share on the date of grant.

                                   (B)    granted to any other Employee, the per
Share exercise price shall be no less than 100% of the Fair Market Value per
Share on the date of grant.

                            (ii)   In the case of a Nonstatutory Stock Option,
the per Share exercise price shall be determined by the Committee.

              (b)    The consideration to be paid for the Shares to be issued
upon exercise of an Option, including the method of payment, shall be determined
by the Administrator (and, in the case of an Incentive Stock Option, shall be
determined at the time of grant) and, in the case of a Prior TSSI ISO may
consist entirely of (1) cash, (2) check, or (3) other Shares which (x) in the
case of Shares acquired upon exercise of an Option, have been owned by the
Optionee for more than six months on the date of surrender, and (y) have a Fair
Market Value on the date of surrender equal to the aggregate exercise price of
the Shares as to which said Option shall be exercised.  In the case of all other
Options, the consideration may consist entirely of (1) cash, (2) check,
(3) promissory note, (4) other Shares which (x) in the case of Shares acquired
upon exercise of an Option, have been owned by the Optionee for more than six
months on the date of surrender, and (y) have a Fair Market Value on the date of
surrender equal to the aggregate exercise price of the Shares as to which said
Option shall be exercised, (5) delivery of a properly executed exercise notice
together with such other documentation as the Administrator and the broker, if
applicable, shall require to effect an exercise of the Option and delivery to
the Company of the sale or loan proceeds required to pay the exercise price, or
(6) any combination of the foregoing methods of payment.  In making its
determination as to the type of consideration to accept, the Board shall
consider if acceptance of such consideration may be reasonably expected to
benefit the Company.

                                    -7-

       9.     EXERCISE OF OPTION.

              (a)    PROCEDURE FOR EXERCISE; RIGHTS AS A STOCKHOLDER. Any
Nonstatutory Option and, subject to the $100,000 limitation of Section 5(b) on
the exercisability of Incentive Stock Options in any one year, any Incentive
Stock Option granted hereunder shall be exercisable under such conditions as
determined by the Board, including performance criteria with respect to the
Company and/or the Optionee, and as shall be permissible under the terms of the
Plan.

                     An Option may not be exercised for a fraction of a Share.

                     An Option shall be deemed to be exercised when written
notice of such exercise has been given to the Company in accordance with the
terms of the Option by the person entitled to exercise the Option and full
payment for the Shares with respect to which the Option is exercised has been
received by the Company.  Full payment may, as authorized by the Board, consist
of any consideration and method of payment allowable under Section 8(b) of the
Plan.  Until the issuance (as evidenced by the appropriate entry on the books of
the Company or of a duly authorized transfer agent of the Company) of the stock
certificate evidencing such Shares, no right to vote or receive dividends or any
other rights as a stockholder shall exist with respect to the Optioned Stock,
notwithstanding the exercise of the Option.  The Company shall issue (or cause
to be issued) such stock certificate promptly upon exercise of the Option.  No
adjustment shall be made for a dividend or other right for which the record date
is prior to the date the stock certificate is issued, except as provided in
Section 11 of the Plan.

                     Exercise of an Option in any manner shall result in a
decrease in the number of Shares which thereafter may be available, both for
purposes of the Plan and for sale under the Option, by the number of Shares as
to which the Option is exercised.

              (b)    TERMINATION OF EMPLOYMENT OR CONSULTING RELATIONSHIP. In
the event of termination of an Optionee's Continuous Status as an Employee or
Consultant with the Company, such Optionee may within sixty (60) days after the
date of such termination (but in no event later than the expiration date of the
term of such Option as set forth in the Option Agreement), exercise his or her
Option to the extent that Optionee was entitled to exercise it at the date of
such termination.  To the extent that Optionee was not entitled to exercise the
Option at the date of such termination, or if Optionee does not exercise such
Option to the extent so entitled within the time specified herein, the Option
shall terminate.  Notwithstanding the above provisions of this Section 9(b), in
the event of an Optionee's change of status from Consultant to Employee, an
Optionee's Nonstatutory Stock Option shall not automatically terminate solely as
a result of such change of status.  In addition, in the case of an Option other
than a Prior TSSI ISO, in the event of an Optionee's change of status from
Employee to Consultant, an Employee's Incentive Stock Option shall not
automatically terminate but shall cease to be treated as an Incentive Stock
Option and shall be treated for tax purposes as a Nonstatutory Stock Option on
the ninety-first (91st) day following such change of status.  

                                    -8-

<PAGE>

              (c)    DISABILITY OF OPTIONEE.  In the event that an Optionee's
Continuous Status as an Employee or Consultant terminates as a result of the
Optionee's Disability, the Optionee may exercise his or her Option at any time
within twelve (12) months from the date of such termination, but only to the
extent that the Optionee was entitled to exercise it at the date of such
termination (but in no event later than the expiration of the term of such
Option as set forth in the Option Agreement).  If, at the date of termination,
the Optionee is not entitled to exercise his or her entire Option, the Shares
covered by the unexercisable portion of the Option shall revert to the Plan. 
If, after termination, the Optionee does not exercise his or her Option within
the time specified herein, the Option shall terminate, and the Shares covered by
such Option shall revert to the Plan.

              (d)    DEATH OF OPTIONEE.  In the event of the death of an
Optionee, the Option may be exercised at any time within twelve (12) months
following the date of death (but in no event later than the expiration of the
term of such Option as set forth in the Option Agreement), by the Optionee's
estate or by a person who acquired the right to exercise the Option by bequest
or inheritance, but only to the extent that the Optionee was entitled to
exercise the Option at the date of death.  If, at the time of death, the
Optionee was not entitled to exercise his or her entire Option, the Shares
covered by the unexercisable portion of the Option shall immediately revert to
the Plan.  If, after death, the Optionee's estate or a person who acquired the
right to exercise the Option by bequest or inheritance does not exercise the
Option within the time specified herein, the Option shall terminate, and the
Shares covered by such Option shall revert to the Plan.

              (e)    RULE 16b-3.  Options granted to persons subject to
Section 16(b) of the Exchange Act must comply with Rule 16b-3 and shall contain
such additional conditions or restrictions as may be required thereunder to
qualify for the maximum exemption from Section 16 of the Exchange Act with
respect to Plan transactions.

              (f)    BUYOUT PROVISIONS.  The Administrator may at any time offer
to buy out for a payment in cash or Shares, an Option previously granted, based
on such terms and conditions as the Administrator shall establish and
communicate to the Optionee at the time that such offer is made.

       10.    NON-TRANSFERABILITY OF OPTIONS.  Options may not be sold, pledged,
assigned, hypothecated, transferred, or disposed of in any manner other than by
will or by the laws of descent or distribution and may be exercised, during the
lifetime of the Optionee, only by the Optionee.

       11.    ADJUSTMENTS UPON CHANGES IN CAPITALIZATION OR MERGER.

              (a)    CHANGES IN CAPITALIZATION.  Subject to any required action
by the stockholders of the Company, the number of shares of Common Stock covered
by each outstanding Option, and the number of shares of Common Stock which have
been authorized for 

                                    -9-

<PAGE>

issuance under the Plan but as to which no Options have yet been granted or 
which have been returned to the Plan upon cancellation or expiration of an 
Option, as well as the price per share of Common Stock covered by each such 
outstanding Option, shall be proportionately adjusted for any increase or 
decrease in the number of issued shares of Common Stock resulting from a 
stock split, reverse stock split, stock dividend, combination or 
reclassification of the Common Stock, or any other increase or decrease in 
the number of issued shares of Common Stock effected without receipt of 
consideration by the Company; provided, however, that conversion of any 
convertible securities of the Company shall not be deemed to have been 
"effected without receipt of consideration."  Such adjustment shall be made 
by the Board, whose determination in that respect shall be final, binding and 
conclusive. Except as expressly provided herein, no issuance by the Company 
of shares of stock of any class, or securities convertible into shares of 
stock of any class, shall affect, and no adjustment by reason thereof shall 
be made with respect to, the number or price of shares of Common Stock 
subject to an Option.

              (b)    DISSOLUTION OR LIQUIDATION.  In the event of the proposed
dissolution or liquidation of the Company, the Administrator shall notify each
Optionee as soon as practicable prior to the effective date of such proposed
transaction.  The Optionee shall have the right to exercise his or her Option
until ten (10) days prior to such transaction as to all of the Optioned Stock
covered thereby.  In addition, any Company repurchase option applicable to
Shares shall lapse as to all such Shares, provided such transaction takes place
at the time and in the manner contemplated.  To the extent it has not been
previously exercised, the Option will terminate immediately prior to the
consummation of such proposed action.

              (c)    MERGER OR ASSET SALE.  In the event of a merger of the
Company with or into another corporation, or the sale of substantially all of
the assets of the Company:

                            (i)    OPTIONS.  Each Option shall be assumed or an
equivalent Option shall be substituted by such successor corporation (including
as a "Successor" any purchaser of substantially all of the assets of the
Company) or a parent or subsidiary of such successor corporation.  In the event
that the successor corporation or a parent or subsidiary of such successor
corporation does not agree to assume the Option or to substitute an equivalent
option, the Administrator shall, as soon as practicable prior to the effective
date of such transaction, provide for the Optionee to have the right to exercise
the Option as to all or a portion of the Optioned Stock, including Shares that
would not otherwise be exercisable.  In such event the Administrator shall
notify the Optionee as soon as practicable prior to the effective date of such
transaction that the Option shall be fully exercisable for a period of ten (10)
days from the date of such notice, and the Option shall terminate upon the
expiration of such period.  For the purposes of this paragraph, the Option shall
be considered assumed if, following the merger, the Option confers the right to
purchase, for each Share of Optioned Stock subject to the Option immediately
prior to the merger, the consideration (whether stock, cash, or other securities
or property) received in the merger by holders of Common Stock for each Share
held on the effective date of the transaction (and if holders were offered a
choice of consideration, the type of consideration 

                                    -10-

<PAGE>

chosen by the holders of a majority of the outstanding Shares); provided, 
however, that if such consideration received in the merger was not solely 
common stock of the successor corporation or its Parent, the Administrator 
may, with the consent of the successor corporation, provide for the 
consideration to be received upon the exercise of the Option, for each Share 
of Optioned Stock subject to the Option, to be solely common stock of the 
successor corporation or its Parent equal in fair market value to the per 
share consideration received by holders of Common Stock in the merger.

                            (ii)   SHARES SUBJECT TO REPURCHASE OPTION.  Any
Shares subject to a repurchase option of the Company shall be exchanged for the
consideration (whether stock, cash, or other securities or property) received in
the merger or asset sale by the holders of Common Stock for each Share held on
the effective date of the transaction, as described in the preceding paragraph. 
If the Optionee receives shares of stock of the successor corporation or a
parent or subsidiary of such successor corporation in exchange for Shares
subject to a repurchase option, such exchanged shares shall continue to be
subject to the repurchase option as provided in the Restricted Stock Purchase
Agreement.

       12.    TIME OF GRANTING OPTIONS.  The date of grant of an Option shall,
for all purposes, be the date on which the Administrator makes the determination
granting such Option, or such other date as is determined by the Board.  Notice
of the determination shall be given to each Employee or Consultant to whom an
Option is so granted within a reasonable time after the date of such grant.

       13.    AMENDMENT AND TERMINATION OF THE PLAN.

              (a)    AMENDMENT AND TERMINATION.  The Board may at any time
amend, alter, suspend or discontinue the Plan, but no amendment, alteration,
suspension or discontinuation shall be made which would impair the rights of any
Optionee under any grant theretofore made, without his or her consent.  In
addition, to the extent necessary and desirable to comply with Rule 16b-3 under
the Exchange Act or with Section 422 of the Code (or any other applicable law or
regulation, including the requirements of Nasdaq or an established stock
exchange), the Company shall obtain stockholder approval of any Plan amendment
in such a manner and to such a degree as required.

              (b)    EFFECT OF AMENDMENT OR TERMINATION.  Any such amendment or
termination of the Plan shall not affect Options already granted, and such
Options shall remain in full force and effect as if this Plan had not been
amended or terminated, unless mutually agreed otherwise between the Optionee and
the Board, which agreement must be in writing and signed by the Optionee and the
Company.

       14.    CONDITIONS UPON ISSUANCE OF SHARES.  Shares shall not be issued
pursuant to the exercise of an Option unless the grant and exercise of such
Option and the issuance and delivery 

                                    -11-

<PAGE>

of such Shares pursuant thereto shall comply with all relevant provisions of 
law, including, without limitation, the Securities Act of 1933, as amended, 
the Exchange Act, the rules and regulations promulgated thereunder, and the 
requirements of Nasdaq or any stock exchange upon which the Shares may then 
be listed, and shall be further subject to the approval of counsel for the 
Company with respect to such compliance.

              As a condition to the exercise of an Option, the Company may
require the person exercising such Option to represent and warrant at the time
of any such exercise that the Shares are being purchased only for investment and
without any present intention to sell or distribute such Shares if, in the
opinion of counsel for the Company, such a representation is required by any of
the aforementioned relevant provisions of law.

       15.    RESERVATION OF SHARES.  The Company, during the term of this Plan,
will at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.

              The inability of the Company to obtain authority from any
regulatory body having jurisdiction, which authority is deemed by the Company's
counsel to be necessary to the lawful issuance and sale of any Shares hereunder,
shall relieve the Company of any liability in respect of the failure to issue or
sell such Shares as to which such requisite authority shall not have been
obtained.

       16.    AGREEMENTS.  Options shall be evidenced by written agreements in
such form as the Administrator shall approve from time to time.

       17.    STOCKHOLDER APPROVAL.  Continuance of the Plan shall be subject to
approval by the stockholders of the Company within twelve (12) months before or
after the date the Plan is adopted.  Such stockholder approval shall be obtained
in the degree and manner required under applicable state and federal law and the
rules of any stock exchange upon which the Common Stock is listed.

       18.    ADDENDUM TO THE 1994 SUMMIT DESIGN, INC. STOCK PLAN.  This
Addendum shall apply to any person who is granted an Option under the 1994
Summit Design, Inc. Stock Plan (the "Plan") and is an employee or consultant of
SEE and is a resident of the State of Israel, or is otherwise subject to the
laws of the State of Israel (such persons are referred to collectively
hereinafter as the "Israelis").

              The Summit Design, Inc. Option Agreements and Restricted Stock
Purchase Agreements delivered to the Israelis pursuant to the Options granted to
the Israelis (each an "Israeli Option") shall contain certain terms and
conditions as is required by applicable Israeli law or approved by the Company,
including, but not limited to the following: 

                                    -12-

              1)     Each Israeli Option granted to an Israeli on or before
January 31, 1994 shall be immediately exercisable for 25% of the shares subject
to such Option, with the remaining Shares to vest equally on a monthly basis
over a three year period beginning on January 1, 1994.  Such vesting schedule
may be accelerated by the Administrator of the Plan and shall be accelerated in
accordance with any employment agreement an Israeli may have with the Company.

              2)     The Common Stock issuable upon exercise of an Israeli
Option that is not yet vested shall be held in escrow and trust in Israel for
the benefit of the Company and the applicable Israeli Optionee as required by
Israeli law and according to the terms and conditions of such Israeli Optionee's
Restricted Stock Purchase Agreement.

              3)     To the fullest extent possible, all terms and conditions
necessary to qualify each Israeli Option intended by the Company to be taxed as
the Israeli equivalent of an Incentive Stock Option or Nonstatutory Option, as
the case may be, to be so taxed by the State of Israel.

              4)     All applicable foreign currency control requirements of any
Israeli governmental entity.

Trading Day on or after May 1 and November 1 each year, or on such other date as
the Board shall determine, and continuing thereafter until terminated in
accordance with Section 19 hereof.  The first Offering Period shall begin on the
effective date of the initial public offering of the Company's Common Stock that
is filed with the Securities and Exchange Commission and shall end on the last
Trading Day on or before October 31, 1998. The Board shall have the power to
change the duration of Offering Periods (including the commencement dates
thereof) with respect to future offerings without stockholder approval if such
change is announced at least five (5) days prior to the scheduled beginning of
the first Offering Period to be affected thereafter.

     5.   PARTICIPATION.

                                    -3-

<PAGE>

          (a)  An eligible Employee may become a participant in the Plan by
completing a subscription agreement authorizing payroll deductions in the form
of Exhibit A to this Plan and filing it with the Company's payroll office prior
to the applicable Enrollment Date.

          (b)  Payroll deductions for a participant shall commence on the first
payroll following the Enrollment Date and shall end on the last payroll in the
Offering Period to which such authorization is applicable, unless sooner
terminated by the participant as provided in Section 10 hereof. 

     6.   PAYROLL DEDUCTIONS.

          (a)  At the time a participant files his or her subscription
agreement, he or she shall elect to have payroll deductions made on each pay day
during the Offering Period in an amount not exceeding ten percent (10%) of the
Compensation which he or she receives on each pay day during the Offering
Period. 

          (b)  All payroll deductions made for a participant shall be credited
to his or her account under the Plan and shall be withheld in whole percentages
only.  A participant may not make any additional payments into such account.

          (c)  A participant may discontinue his or her participation in the
Plan as provided in Section 10 hereof, or may increase or decrease the rate of
his or her payroll deductions during the Offering Period by completing or filing
with the Company a new subscription agreement authorizing a change in payroll
deduction rate.  The Board may, in its discretion, limit the number of
participation rate changes during any Offering Period.  The change in rate shall
be effective with the first full payroll period following five (5) business days
after the Company's receipt of the new subscription agreement unless the Company
elects to process a given change in participation more quickly.  A participant's
subscription agreement shall remain in effect for successive Offering Periods
unless terminated as provided in Section 10 hereof.

          (d)  Notwithstanding the foregoing, to the extent necessary to comply
with Section 423(b)(8) of the Code and Section 3(b) hereof, a participant's
payroll deductions may be decreased to zero percent (0%) at such time during any
Purchase Period which is scheduled to end during the current calendar year (the
"Current Purchase Period") that the aggregate of all payroll deductions which
were previously used to purchase stock under the Plan in a prior Purchase Period
which ended during that calendar year plus all payroll deductions accumulated
with respect to the Current Purchase Period equal $21,250.  Payroll deductions
shall recommence at the rate provided in such participant's subscription
agreement at the beginning of the first Purchase Period which is scheduled to
end in the following calendar year, unless terminated by the participant as
provided in Section 10 hereof.

                                    -4-

<PAGE>

          (e)  At the time the option is exercised, in whole or in part, or at
the time some or all of the Company's Common Stock issued under the Plan is
disposed of, the participant must make adequate provision for the Company's
federal, state, or other tax withholding obligations, if any, which arise upon
the exercise of the option or the disposition of the Common Stock.  At any time,
the Company may, but shall not be obligated to, withhold from the participant's
compensation the amount necessary for the Company to meet applicable withholding
obligations, including any withholding required to make available to the Company
any tax deductions or benefits attributable to sale or early disposition of
Common Stock by the Employee. 

     7.   GRANT OF OPTION.  On the Enrollment Date of each Offering Period, each
eligible Employee participating in such Offering Period shall be granted an
option to purchase on each Exercise Date during such Offering Period (at the
applicable Purchase Price) up to a number of shares of the Company's Common
Stock determined by dividing such Employee's payroll deductions accumulated
prior to such Exercise Date and retained in the Participant's account as of the
Exercise Date by the applicable Purchase Price; provided that in no event shall
an Employee be permitted to purchase during each Purchase Period more than a
number of shares determined by dividing $12,500 by the Fair Market Value of a
share of the Company's Common Stock on the Enrollment Date, and provided further
that such purchase shall be subject to the limitations set forth in
Sections 3(b) and 12 hereof. Exercise of the option shall occur as provided in
Section 8 hereof, unless the participant has withdrawn pursuant to Section 10
hereof.  The option shall expire on the last day of the Offering Period. 

     8.   EXERCISE OF OPTION.  Unless a participant withdraws from the Plan as
provided in Section 10 hereof, his or her option for the purchase of shares
shall be exercised automatically on the Exercise Date, and the maximum number of
full shares subject to option shall be purchased for such participant at the
applicable Purchase Price with the accumulated payroll deductions in his or her
account.  No fractional shares shall be purchased; any payroll deductions
accumulated in a participant's account which are not sufficient to purchase a
full share shall be retained in the participant's account for the subsequent
Purchase Period or Offering Period, subject to earlier withdrawal by the
participant as provided in Section 10 hereof.  Any other monies left over in a
participant's account after the Exercise Date shall be returned to the
participant.  During a participant's lifetime, a participant's option to
purchase shares hereunder is exercisable only by him or her.

     9.   DELIVERY.  As promptly as practicable after each Exercise Date on
which a purchase of shares occurs, the Company shall arrange the delivery to
each participant, as appropriate, of a certificate representing the shares
purchased upon exercise of his or her option.

     10.  WITHDRAWAL; TERMINATION OF EMPLOYMENT.

          (a)  A participant may withdraw all but not less than all the payroll
deductions credited to his or her account and not yet used to exercise his or
her option under the Plan at any 

                                    -5-

<PAGE>

time by giving written notice to the Company in the form of Exhibit B to this 
Plan.  All of the participant's payroll deductions credited to his or her 
account shall be paid to such participant promptly after receipt of notice of 
withdrawal and such participant's option for the Offering Period shall be 
automatically terminated, and no further payroll deductions for the purchase 
of shares shall be made for such Offering Period.  If a participant withdraws 
from an Offering Period, payroll deductions shall not resume at the beginning 
of the succeeding Offering Period unless the participant delivers to the 
Company a new subscription agreement.

          (b)  Upon a participant's ceasing to be an Employee (as defined in
Section 2(g) hereof), for any reason, he or she shall be deemed to have elected
to withdraw from the Plan and the payroll deductions credited to such
participant's account during the Offering Period but not yet used to exercise
the option shall be returned to such participant or, in the case of his or her
death, to the person or persons entitled thereto under Section 14 hereof, and
such participant's option shall be automatically terminated.  The preceding
sentence notwithstanding, a participant who receives payment in lieu of notice
of termination of employment shall be treated as continuing to be an Employee
for the participant's customary number of hours per week of employment during
the period in which the participant is subject to such payment in lieu of
notice.

          (c)  A participant's withdrawal from an Offering Period shall not have
any effect upon his or her eligibility to participate in any similar plan which
may hereafter be adopted by the Company or in succeeding Offering Periods which
commence after the termination of the Offering Period from which the participant
withdraws.

     11.  INTEREST.  No interest shall accrue on the payroll deductions of a
participant in the Plan.

     12.  STOCK.

          (a)  The maximum number of shares of the Company's Common Stock which
shall be made available for sale under the Plan shall be 150,000 shares, subject
to adjustment upon changes in capitalization of the Company as provided in
Section 18 hereof.  If, on a given Exercise Date, the number of shares with
respect to which options are to be exercised exceeds the number of shares then
available under the Plan, the Company shall make a pro rata allocation of the
shares remaining available for purchase in as uniform a manner as shall be
practicable and as it shall determine to be equitable.

          (b)  The participant shall have no interest or voting right in shares
covered by his option until such option has been exercised.

          (c)  Shares to be delivered to a participant under the Plan shall be
registered in the name of the participant or in the name of the participant and
his or her spouse.

                                    -6-

<PAGE>

     13.  ADMINISTRATION.

          (a)  ADMINISTRATIVE BODY.  The Plan shall be administered by the Board
or a committee of members of the Board appointed by the Board.  The Board or its
committee shall have full and exclusive discretionary authority to construe,
interpret and apply the terms of the Plan, to determine eligibility and to
adjudicate all disputed claims filed under the Plan.  Every finding, decision
and determination made by the Board or its committee shall, to the full extent
permitted by law, be final and binding upon all parties.

          (b)  RULE 16b-3 LIMITATIONS.  Notwithstanding the provisions of
Subsection (a) of this Section 13, in the event that Rule 16b-3 promulgated
under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), or
any successor provision ("Rule 16b-3") provides specific requirements for the
administrators of plans of this type, the Plan shall be administered only by
such a body and in such a manner as shall comply with the applicable
requirements of Rule 16b-3.  Unless permitted by Rule 16b-3, no discretion
concerning decisions regarding the Plan shall be afforded to any committee or
person that is not "disinterested" as that term is used in Rule 16b-3.

     14.  DESIGNATION OF BENEFICIARY.

          (a)  A participant may file a written designation of a beneficiary who
is to receive any shares and cash, if any, from the participant's account under
the Plan in the event of such participant's death subsequent to an Exercise Date
on which the option is exercised but prior to delivery to such participant of
such shares and cash.  In addition, a participant may file a written designation
of a beneficiary who is to receive any cash from the participant's account under
the Plan in the event of such participant's death prior to exercise of the
option.  If a participant is married and the designated beneficiary is not the
spouse, spousal consent shall be required for such designation to be effective.

          (b)  Such designation of beneficiary may be changed by the participant
at any time by written notice.  In the event of the death of a participant and
in the absence of a beneficiary validly designated under the Plan who is living
at the time of such participant's death, the Company shall deliver such shares
and/or cash to the executor or administrator of the estate of the participant,
or if no such executor or administrator has been appointed (to the knowledge of
the Company), the Company, in its discretion, may deliver such shares and/or
cash to the spouse or to any one or more dependents or relatives of the
participant, or if no spouse, dependent or relative is known to the Company,
then to such other person as the Company may designate.

     15.  TRANSFERABILITY.  Neither payroll deductions credited to a
participant's account nor any rights with regard to the exercise of an option or
to receive shares under the Plan may be assigned, transferred, pledged or
otherwise disposed of in any way (other than by will, the laws of descent and
distribution or as provided in Section 14 hereof) by the participant.  Any such
attempt 

                                    -7-

<PAGE>

at assignment, transfer, pledge or other disposition shall be without effect, 
except that the Company may treat such act as an election to withdraw funds 
from an Offering Period in accordance with Section 10 hereof.

     16.  USE OF FUNDS.  All payroll deductions received or held by the Company
under the Plan may be used by the Company for any corporate purpose, and the
Company shall not be obligated to segregate such payroll deductions.

     17.  REPORTS.  Individual accounts shall be maintained for each participant
in the Plan.  Statements of account shall be given to participating Employees at
least annually, which statements shall set forth the amounts of payroll
deductions, the Purchase Price, the number of shares purchased and the remaining
cash balance, if any.

     18.  ADJUSTMENTS UPON CHANGES IN CAPITALIZATION, DISSOLUTION, LIQUIDATION,
          MERGER OR ASSET SALE.

          (a)  CHANGES IN CAPITALIZATION.  Subject to any required action by the
stockholders of the Company, the Reserves, as well as the price per share and
the number of shares of Common Stock covered by each option under the Plan which
has not yet been exercised, shall be proportionately adjusted for any increase
or decrease in the number of issued shares of Common Stock resulting from a
stock split, reverse stock split, stock dividend, combination or
reclassification of the Common Stock, or any other increase or decrease in the
number of shares of Common Stock effected without receipt of consideration by
the Company; provided, however, that conversion of any convertible securities of
the Company shall not be deemed to have been "effected without receipt of
consideration".  Such adjustment shall be made by the Board, whose determination
in that respect shall be final, binding and conclusive.  Except as expressly
provided herein, no issuance by the Company of shares of stock of any class, or
securities convertible into shares of stock of any class, shall affect, and no
adjustment by reason thereof shall be made with respect to, the number or price
of shares of Common Stock subject to an option.

          (b)  DISSOLUTION OR LIQUIDATION.  In the event of the proposed
dissolution or liquidation of the Company, the Offering Periods shall terminate
immediately prior to the consummation of such proposed action, unless otherwise
provided by the Board.

          (c)  MERGER OR ASSET SALE.  In the event of a proposed sale of all 
or substantially all of the assets of the Company, or the merger of the 
Company with or into another corporation, any Purchase Periods then in 
progress shall be shortened by setting a new Exercise Date (the "New Exercise 
Date") and any Offering Periods then in progress shall end on the New 
Exercise Date.  The New Exercise Date shall be before the date of the 
Company's proposed sale or merger. The Board shall notify each participant in 
writing, at least ten (10) business days prior to the New Exercise Date, that 
the Exercise Date for the participant's option has been changed to the New 
Exercise Date and that the participant's option shall be exercised 
automatically on the New 

                                    -8-

<PAGE>

Exercise Date, unless prior to such date the participant has withdrawn from 
the Offering Period as provided in Section 10 hereof.

     19.  AMENDMENT OR TERMINATION.

          (a)  The Board of Directors of the Company may at any time and for any
reason terminate or amend the Plan.  Except as provided in Section 18 hereof, no
such termination can affect options previously granted, provided that an
Offering Period may be terminated by the Board of Directors on any Exercise Date
if the Board determines that the termination of the Plan is in the best
interests of the Company and its stockholders.  Except as provided in Section 18
hereof, no amendment may make any change in any option theretofore granted which
adversely affects the rights of any participant.  To the extent necessary to
comply with Rule 16b-3 or under Section 423 of the Code (or any successor rule
or provision or any other applicable law or regulation), the Company shall
obtain stockholder approval in such a manner and to such a degree as required.

          (b)  Without stockholder consent and without regard to whether any
participant rights may be considered to have been "adversely affected," the
Board (or its committee) shall be entitled to change the Offering Periods, limit
the frequency and/or number of changes in the amount withheld during an Offering
Period, establish the exchange ratio applicable to amounts withheld in a
currency other than U.S. dollars, permit payroll withholding in excess of the
amount designated by a participant in order to adjust for delays or mistakes in
the Company's processing of properly completed withholding elections, establish
reasonable waiting and adjustment periods and/or accounting and crediting
procedures to ensure that amounts applied toward the purchase of Common Stock
for each participant properly correspond with amounts withheld from the
participant's Compensation, and establish such other limitations or procedures
as the Board (or its committee) determines in its sole discretion advisable
which are consistent with the Plan.

     20.  NOTICES.  All notices or other communications by a participant to the
Company under or in connection with the Plan shall be deemed to have been duly
given when received in the form specified by the Company at the location, or by
the person, designated by the Company for the receipt thereof.

     21.  CONDITIONS UPON ISSUANCE OF SHARES.  Shares shall not be issued with
respect to an option unless the exercise of such option and the issuance and
delivery of such shares pursuant thereto shall comply with all applicable
provisions of law, domestic or foreign, including, without limitation, the
Securities Act of 1933, as amended, the Securities Exchange Act of 1934, as
amended, the rules and regulations promulgated thereunder, and the requirements
of any stock exchange upon which the shares may then be listed, and shall be
further subject to the approval of counsel for the Company with respect to such
compliance.

                                    -9-

<PAGE>

          As a condition to the exercise of an option, the Company may require
the person exercising such option to represent and warrant at the time of any
such exercise that the shares are being purchased only for investment and
without any present intention to sell or distribute such shares if, in the
opinion of counsel for the Company, such a representation is required by any of
the aforementioned applicable provisions of law.

     22.  TERM OF PLAN.  The Plan shall become effective upon the earlier to
occur of its adoption by the Board of Directors or its approval by the
stockholders of the Company.  It shall continue in effect for a term of ten (10)
years unless sooner terminated under Section 19 hereof.

     23.  AUTOMATIC TRANSFER TO LOW PRICE OFFERING PERIOD.  To the extent
permitted by Rule 16b-3 of the Exchange Act, if the Fair Market Value of the
Common Stock on any Exercise Date in an Offering Period is lower than the Fair
Market Value of the Common Stock on the Enrollment Date of such Offering Period,
then all participants in such Offering Period shall be automatically withdrawn
from such Offering Period immediately after the exercise of their option on such
Exercise Date and automatically re-enrolled in the immediately following
Offering Period as of the first day thereof.

                                SUBSCRIPTION AGREEMENT



_____ Original Application                        Enrollment Date: ___________
_____ Change in Payroll Deduction Rate
_____ Change of Beneficiary(ies)


1.   ____________________________________________________  hereby elects to
     participate in the Summit Design, Inc. 1996 Employee Stock Purchase Plan
     (the "Employee Stock Purchase Plan") and subscribes to purchase shares of
     the Company's Common Stock in accordance with this Subscription Agreement
     and the Employee Stock Purchase Plan.

2.   I hereby authorize payroll deductions from each paycheck in the amount of
     ____% of my Compensation on each payday (from 1 to 10%) during the Offering
     Period in accordance with the Employee Stock Purchase Plan.  (Please note
     that no fractional percentages are permitted.)

3.   I understand that said payroll deductions shall be accumulated for the
     purchase of shares of Common Stock at the applicable Purchase Price
     determined in accordance with the Employee Stock Purchase Plan.  I
     understand that if I do not withdraw from an Offering Period, any
     accumulated payroll deductions will be used to automatically exercise my
     option.

4.   I have received a copy of the complete Employee Stock Purchase Plan.  I
     understand that my participation in the Employee Stock Purchase Plan is in
     all respects subject to the terms of the Plan.  I understand that my
     ability to exercise the option under this Subscription Agreement is subject
     to stockholder approval of the Employee Stock Purchase Plan.

5.   Shares purchased for me under the Employee Stock Purchase Plan should be
     issued in the name(s) of (Employee or Employee and Spouse only):__________
     _________________________________.

6.   I understand that if I dispose of any shares received by me pursuant to the
     Plan within 2 years after the Enrollment Date (the first day of the
     Offering Period during which I purchased such shares) or one year after the
     Exercise Date, I will be treated for federal income tax purposes as having
     received ordinary income at the time of such disposition in 

<PAGE>

     an amount equal to the excess of the fair market value of the shares at 
     the time such shares were purchased by me over the price which I paid 
     for the shares.  I HEREBY AGREE TO NOTIFY THE COMPANY IN WRITING WITHIN 
     30 DAYS AFTER THE DATE OF ANY DISPOSITION OF MY SHARES AND I WILL MAKE 
     ADEQUATE PROVISION FOR FEDERAL, STATE OR OTHER TAX WITHHOLDING 
     OBLIGATIONS, IF ANY, WHICH ARISE UPON THE DISPOSITION OF THE COMMON 
     STOCK.  The Company may, but will not be obligated to, withhold from my 
     compensation the amount necessary to meet any applicable withholding 
     obligation including any withholding necessary to make available to the 
     Company any tax deductions or benefits attributable to sale or early 
     disposition of Common Stock by me. If I dispose of such shares at any 
     time after the expiration of the 2-year and 1-year holding periods, I 
     understand that I will be treated for federal income tax purposes as 
     having received income only at the time of such disposition, and that 
     such income will be taxed as ordinary income only to the extent of an 
     amount equal to the lesser of (1) the excess of the fair market value of 
     the shares at the time of such disposition over the purchase price which 
     I paid for the shares, or (2) 15% of the fair market value of the shares 
     on the first day of the Offering Period.  The remainder of the gain, if 
     any, recognized on such disposition will be taxed as capital gain.

7.   I hereby agree to be bound by the terms of the Employee Stock Purchase
     Plan.  The effectiveness of this Subscription Agreement is dependent upon
     my eligibility to participate in the Employee Stock Purchase Plan.

8.   In the event of my death, I hereby designate the following as my
     beneficiary(ies) to receive all payments and shares due me under the
     Employee Stock Purchase Plan:
