                                   401(k) PLAN

         The ECAD, Inc. Cash or Deferred Profit Sharing Plan was originally
established effective January 1, 1984 and was revised effective January 1, 1985.
Effective June 1, 1988, as a result of the merger of ECAD, Inc. and SDA Systems,
Inc. and the subsequent renaming of the corporation, the name of the ECAD, Inc.
Cash or Deferred Profit Sharing Plan was changed to the Cadence Design Systems,
Inc. Cash or Deferred Profit Sharing Plan (the "Prior Plan"). Effective as of
January 1, 1989, Cadence Design Systems, Inc., a Delaware corporation (the
"Employer"), renamed, amended and restated the Prior Plan as the Cadence Design
Systems, Inc. 401(k) Plan (the "Plan"). Since this last amendment and
restatement, the Plan has been further amended several times. Effective as of
July 1, 1995, unless specifically provided otherwise, the Employer hereby again
amends and restates the Plan in its entirety. The Plan is established for the
purpose of (a) providing the employees with an opportunity to accumulate funds
for their retirement, or (b) for the payment of death benefits for their
dependents and beneficiaries. The Plan is a profit sharing plan which is
intended to qualify under section 401(a) of the Internal Revenue Code of 1986,
as amended (the "Code"), and has a tax-deferred retirement savings feature which
is intended to satisfy the requirements of section 401(k) of the Code.

                         (e) The value of a non-qualified stock option granted
to an Employee by the Employer, but only to the extent that the value of the

income (as defined in section 911(b) of the Code), whether or not excludable
from gross income under section 911(b) of the Code. Compensation in items (a)

                    (2) For the purposes of subparagraph (a)(i) above,
"Compensation" shall exclude the following:

                         (a) Contributions made by the Employer to a plan of
deferred compensation to the extent that, before the application of the Code's
section 415 limitations to that plan, the contributions are not includable in
the gross income of the Employee for the taxable year in which contributed. In
addition, Employer contributions made on behalf of an Employee to a simplified
employee pension plan described in section 408(k) of the Code are not considered
as Compensation for the taxable year in which contributed. Additionally, any
distributions from a plan of deferred compensation are not considered as
Compensation for


                                       20
   6
purposes of section 415 of the Code, regardless of whether such amounts are
includable in the gross income of the Employee when distributed. However, any
amounts received by an Employee pursuant to an unfunded non-qualified plan may
be considered as Compensation for, purposes of section 415 of the Code in the
Plan Year such amounts are includable in the gross income of the Employee.

                         (b) Amounts realized from the exercise of a
nonqualified stock option, or when restricted stock (or property) held by an

disposition of stock acquired under a qualified stock option.

                         (d) Other amounts which receive special tax benefits,
such as premiums for group term life insurance (but only to the extent that the
premiums are not includable in the gross income of the Employee), or

agreement) towards the purchase of an annuity contract described in section
403(b) of the Code (whether or not the contributions are excludable from the
gross income of the employee).

                         (3) Compensation (as defined in subparagraph (A)(1)
above) shall be Compensation actually paid or made available to an Employee

section 3401(a) of the Code and all other payments of compensation to an
Employee by his Employer (in the course of the Employer's trade or business) for
which the Employer is required to furnish the Employee a written statement under
sections 6041(d), 6051(a)(3) and 6052 of the Code. At the discretion of the
Committee, this definition of Compensation may be modified to exclude amounts
paid or reimbursed by the Employer for moving expenses incurred by an Employee,
but only to the extent that at the time of the payment it is reasonable to
believe that these amounts are deductible by the Employee under section 217 of
the Code. Compensation under this subparagraph must be determined without regard
to any rules under section 3401(a) of the Code that limit the remuneration
included in wages based on the nature or location of the employment or the
services performed (such as the exception for agricultural labor in section
3401(a)(2) of the Code).

                    (D) Compensation for tax withholding under section 3401(a)
of the Code, which shall include wages as defined in section 3401(a) of the Code
for purposes of income tax withholding at the source but determined without
regard to any rules that limit the remuneration included in wages based on the


                                       21
   7
nature or location of the employment or the services performed (such as the
exception for agricultural labor in section 3401(a)(2) of the Code).

                    (E) Safe harbor alternative definition of Compensation under
section 414(s). Compensation shall mean Compensation as defined in subparagraphs
(A), (B), (C) or (D) above, reduced by all of the following items (even if
includable in gross income): reimbursements or other expense allowances, fringe
benefits (cash and noncash), moving expenses, deferred compensation and welfare
benefits.

               (3) For purposes of this paragraph 1.1(j), the following special
rules shall apply:

                    (A) For all purposes under the Plan:

                         (1) "Compensation" shall include Compensation paid to
any Employee prior to the time the Employee becomes a Participant in the Plan.

                         (2) For Plan Years beginning on or after January 1,
1989, and before January 1, 1994, the annual Compensation of each Participant
taken into account for determining all benefits provided under the Plan for any
Plan Year shall not exceed $200,000. This limitation shall be adjusted by the
Secretary of the Treasury at the same time and in the same manner as under Code
section 415(d), except that the dollar increase in effect on January 1 of any
calendar year is effective for Plan Years beginning in such calendar year and
the first adjustment to the $200,000 limitation is effective on January 1, 1990.
For Plan Years beginning on or after January 1, 1994, the annual Compensation of
each Participant taken into account for any Plan Year shall not exceed $150,000
or, if greater, the maximum dollar amount specified in Code section 401(a)(17),
as adjusted for increases in the cost-of-living in accordance with Code section
401(a)(17)(B). The cost-of-living adjustment in effect for a calendar year
applies to any determination period beginning in such calendar year. If a
determination period consists of fewer than 12 months, the annual Compensation
limit is an amount equal to the otherwise applicable annual Compensation limit
multiplied by a fraction, the numerator of which is the number of months in the
short determination period, and the denominator of which is 12.

                         In determining the Compensation of a Participant for
purposes of this limitation, the rules of Code section 414(q)(6) shall apply,
except in applying such rules, the term "family" shall include only the spouse
of the Participant and any lineal descendants of the Participant who have not
attained age 19 before the close of the Plan Year. If, as a result of the
application of such rules the adjusted annual Compensation limitation is
exceeded, then the limitation shall be prorated among the affected individuals
in proportion to each such individual's Compensation as determined prior to the
application of this limitation.

                    (B) At the discretion of the Committee, "Compensation" of
all Employees under section 1.1(j)(2) may be modified to include all of the
following types of contributions and all of the following types of deferred
compensation:

                                       22

under section 125, section 402(e)(3), section 402(h) and section 403(b) of the
Code;

                         (2) Compensation deferred under an eligible deferred
compensation plan within the meaning of section 457(b) (deferred compensation
plans of state and local governments and tax-exempt organizations); and

                         (3) Employee contributions (under governmental plans)
described in section 414(h)(2) that are picked up by the employing unit and thus
are treated as Employer contributions.

                    (C) At the discretion of the Committee, Compensation under
section 1.1 (h)(2) for all Highly Compensated Employees may be modified to
exclude any portion of the Compensation of some or all of such Highly
Compensated Employees.

                    (D) "Compensation" shall include all amounts paid by a
Related Company which has adopted the Plan.

               (k) "Effective Date" of the Plan, as amended and restated herein,
shall mean January 1, 1989.

               (l) "Eligible Employee" shall mean every Employee except any
Employee (1) who is not a non-resident alien, and who receives no earned income

sources within the United States (within the meaning of section 861(a)(3) of the
Code), (2) who is a member of a collective bargaining unit and who is covered by
a collective bargaining agreement, which agreement does not specifically provide
for coverage of such Employee under the Plan, (3) who is a leased employee as
defined in section 414(n)(2) of the Code, or, (4) who performs services for any
division of the Company that maintains its own plan.

               (m) "Employee" shall mean a person currently employed by the
Employer, any portion of whose income is subject to withholding of income tax
and/or for whom Social Security contributions are made by the Employer, as well
as any other person qualifying as a common law employee of the Employer.
Notwithstanding any other provision of the Plan, for purposes of the
requirements listed in section 414(n)(3) of the Code, the term "Employee" shall
include leased employees within the meaning of section 414(n)(2) of the Code;
provided, however, that if such leased employees constitute less than 20% of the
Employer's Non-Highly compensated workforce within the meaning of section
414(n)(5)(C)(ii) of the Code, the term "Employee" shall not include those leased
employees covered by a plan described in section 414(n)(5) of the Code.

               (n) "Employer" shall mean the Company and any Related Company
which adopts the Plan with the consent of the Company.

                                       23

subparagraphs (1)(B), (1)(C) or (1)(D) above shall not apply to an Employee for
the current Plan Year unless:

                         (A) Such Employee was a Highly Compensated Employee for
the preceding 12-month period by application of subparagraphs (1)(B), (1)(C) or

                              401(k) CONTRIBUTIONS

     3.1 Deferral Authorization.

          (a) Each Participant may designate a whole percentage of his
compensation which is not less than one percent (1%) nor more than twenty
percent (20%) for each Plan Year, which amount shall not be paid to the
Participant but shall, for each pay period during which the authorization is in
effect, be withheld from the Participant's compensation and contributed to his
401(k) Account as provided herein.

          (b) A Participant may initially authorize 401(k) Contributions by
filing such enrollment form or otherwise providing such authorization as the
Committee may specify at least fifteen (15) days prior to the Entry Date on
which such authorization is to be effective. A Participant's 401(k)
Contributions designation shall remain in effect until suspended or modified as
provided in Articles 3.5 and 3.6.

          (c) A participant's compensation shall include salary, bonuses,
overtime, commissions, 401(k) Contributions, and car allowances, but shall not
include salary reduction contributions to any plan maintained by the Company or
a Related Company which is a cafeteria plan as defined by Section 125 of the
Code, or any other payments not specifically included above.

     3.2 Annual Limitation on Deferrals. Notwithstanding any other provision of
the Plan, no Participant shall be permitted to have 401(k) Contributions made to
the Plan on his behalf during any calendar year in excess of $7,000, multiplied
by the Adjustment Factor, or such other amount as may be permitted by law.

     3.3 Distribution of Excess Deferrals.

          (a) Notwithstanding any other provision of the Plan, Excess Deferrals
and income allocable thereto shall be distributed no later than each April 15 to
Participants who claim such Excess Deferrals for the preceding calendar year.
For purposes of this Article 3.3, "Excess Deferrals" shall mean the amount of
401(k) Contributions for a calendar year that the Participant allocates to the
Plan pursuant to the claim procedure set forth in subsection (b) below.

          (b) A Participant's claim for Excess Deferrals shall be in writing;
shall specify the amount of the Participant's Excess Deferrals for the
applicable calendar year; shall be submitted to the Committee no later than
March 1 immediately following the close of the applicable calendar year; and
shall be accompanied by the Participant's written statement that if such amounts
are not distributed, such Excess Deferrals, when added to amounts deferred under
other plans or arrangements described in sections 401(k), 408(k) or 403(b) of
the Code, shall exceed the limit imposed on the Participant by section 402(g) of
the Code for the applicable calendar year.

          (c) A Participant's Excess Deferrals shall be adjusted for income or
loss, which shall be determined by multiplying the total amount of income or
loss allocable to the Participant's 401(k) Account for the 


                                       29
   15
applicable calendar year by a fraction, the numerator of which shall be the
Participant's Excess Deferrals and the denominator of which shall be the balance
in the Participant's 401(k) Account on the last day of the applicable calendar
year.

          (d) The Excess Deferrals which would otherwise be distributed to a
Participant pursuant to this Article 3.3 shall be reduced by the amount of
Excess Contributions previously distributed to such Participant for the Plan
Year, in accordance with regulations promulgated by the Secretary of the
Treasury.

     3.4 All Contributions Deemed Employer Contributions. Except as applicable
law may otherwise require, contributions made pursuant to the Participant's
designation under Article 3.1 shall be deemed to be Employer contributions to
the Plan.

     3.5 Cessation and Resumption of 401(k) Contributions.

          (a) A Participant may cease 401(k) Contributions at any time by filing
with the Committee an Enrollment Form or by communicating with the Committee in
such other manner as the Committee may authorize, which shall be effective as
soon thereafter as may be administratively feasible. A Participant who has
ceased making 401(k) Contributions may resume making 401(k) Contributions as of
any Entry Date thereafter upon filing a new Enrollment Form which complies with
the provisions of Article 3.1(b), provided the Participant is otherwise eligible
to participate in the Plan on that date.

          (b) If the Participant ceases to be an Eligible Employee, all 401(k)
Contributions made on his behalf shall be suspended immediately, but he shall be
eligible to have 401(k) Contributions made on his behalf resumed on the first
Entry Date occurring on or after the date on which he again becomes an Eligible
Employee.

     3.6 Change in 401(k) Contributions. A Participant may change the percentage
of 401(k) Contributions effective as of any Entry Date by filing an Enrollment
Form with the Committee or by communicating with the Committee in such other
manner as the Committee may authorize, prior to the date such change is to be
effective, which form shall specify the increase or decrease in 401(k)
Contributions desired.

     3.7 Actual Deferral Percentage Limitation.

          (a) In order that the Plan comply with the requirements of section
401(k) of the Code, the 401(k) Contributions made for each Plan Year must
satisfy one of the following tests:

               (1) The Actual Deferral Percentage for Participants who are
Highly Compensated Employees for the Plan Year shall not exceed the Actual
Deferral Percentage for Participants who are Non-Highly Compensated Employees
for the Plan Year multiplied by 1.25; or

               (2) The Actual Deferral Percentage for Participants who are
Highly Compensated Employees for the Plan Year shall not exceed the Actual
Deferral Percentage for Participants who are Non-Highly 


                                       30
   16
Compensated Employees for the Plan Year multiplied by 2, provided that the
Actual Deferral Percentage for Participants who are Highly Compensated Employees
does not exceed the Actual Deferral Percentage for Participants who are
Non-Highly Compensated Employees by more than 2 percentage points, or such
lesser amount as the Secretary of the Treasury shall prescribe to prevent the
multiple use of this alternative test with respect to any Highly Compensated
Employee.

          (b) For purposes of this Article 3.7, the following definitions shall
apply:

               (1) "Actual Deferral Percentage" shall mean the average
(expressed as a percentage) of the Deferral Percentages of the Participants in a
group.

               (2) "Deferral Percentage" shall mean the ratio (expressed as a
percentage) that a Participant's 401(k) Contributions made during a Plan Year
bears to the Participant's compensation for such Plan Year.

          (c) For purposes of this Article 3.7, the following special rules
shall apply:

               (1) The Deferral Percentage for any Participant who is a Highly
Compensated Employee for the Plan Year and who is eligible to have elective
deferral contributions allocated to his account under two or more plans or
arrangements described in section 401(k) of the Code that are maintained by the
Company shall be determined as if all such elective deferrals were made under a
single arrangement.

               (2) The Deferral Percentages of any Participant under two or more
arrangements described in section 401(k) of the Code that are maintained by the
Company or a Related Company shall be determined as if all elective deferrals
made by any Participant were made under a single arrangement, if the
arrangements are treated as a single plan for purposes of meeting the
requirements of sections 401(a)(4) and 410(b) (other than section
410(b)(2)(A)(ii)) of the Code.

               (3) For purposes of determining the Deferral Percentage of a
Participant who is a Highly Compensated Employee and is either a 5% owner as
defined in Article 21.5(3)(a) or one of the ten most Highly Compensated
Employees of the Employer, the 401(k) Contributions and compensation of such
Participant shall include the 401(k) Contributions and compensation of Family
Members, and such Family Members shall be disregarded in determining the
Deferral Percentages for Participants who are Non-Highly Compensated Employees.

               (4) As provided in and in accordance with the regulations
promulgated by the Secretary of the Treasury, the Committee may, in its sole
discretion, elect to take into account Matching Contributions and qualified
non-elective contributions, as described in section 401(m) of the Code, made on
behalf of a Participant under the Plan or any other plan of the Company, for
purposes of determining such Participant's Deferral Percentage only if such
contributions are nonforfeitable when made and distributable only under the
following circumstances:

                                       31
   17
                    (A) The Employee's retirement, death, Total Disability or
separation from service:

                    (B) The termination of the Plan without the establishment of
a successor plan;

                    (C) The Employee's attainment of age 59-1/2 or, for Plan
Years beginning before 1989, the Employee's hardship:

                    (D) The sale or other disposition by the Company or a
Related Company to an unrelated corporation, which does not maintain the Plan,
of substantially all of the assets used in a trade or business, but only with
respect to employees who continue employment with the acquiring corporation;

                    (E) The sale or other disposition by the Company or a
Related Company of its interest in a subsidiary to an unrelated entity which
does not maintain the Plan, but only with respect to employees who continue
employment with the subsidiary. Non-elective contributions which may be treated
as 401(k) Contributions must satisfy these requirements without regard to
whether they are actually taken into account as 401(k) Contributions; and

                    (F) Any distribution pursuant to subparagraph 4(b), (d) or
(e) of this section 32.7(c) must be a lump sum distribution (as defined in
section 401(k)(10)(B)) of the Participant's vested interest within one taxable
year.

               (5) The Committee shall maintain such records as are necessary to
demonstrate compliance with the requirements of section 3.7(a), including the
extent to which Matching Contributions and qualified non-elective contributions
are taken into account for purposes of determining a Participant's Deferral
Percentage.

               (6) The determination and treatment of the 401(k) Contributions
and Deferral Percentage of any Participant shall satisfy such other requirements
as may be prescribed by the Secretary of the Treasury.

               (7) 401(k) Contributions shall relate to a Participant's
Compensation that either would have been received by the Participant during the
Plan Year but for the Participant's election to make 401(k) Contributions or is
attributable to services performed by the Participant during the Plan Year and,
but for the Participant's election to make 401(k) Contributions, would have been
received by the Participant within two and one-half months after the close of
the Plan Year.

     3.8 Avoidance and Distribution of Excess Contributions.

          (a) In order that the Plan shall comply with the requirements of
section 401(k) of the Code and the regulations thereunder, at any time in a Plan
Year the Committee (in its sole discretion) may reduce for the remainder of that
Plan Year the rate of 401(k) Contributions authorized by any Participant who is
a Highly Compensated Employee, or the Committee may require that any Highly
Compensated Employee 


                                       32
   18
Participant discontinue all 401(k) Contributions for the remainder of that Plan
Year. Such a reduction or discontinuance may be applied selectively to
individual Highly Compensated Employee Participants or to a particular class of
Highly Compensated Employee Participants, as the Committee may determine. Upon
the close of the Plan Year, or on such earlier date as the Committee may
determine, this Article 3.8 shall automatically cease to apply until the
Committee again determines that a reduction or discontinuance of 401(k)
Contributions is required for any Highly Compensated Employee Participant.

          (b) Notwithstanding any other provision of the Plan, Excess
Contributions and income allocable thereto shall be distributed to Participants
no later than the end of the Plan Year following the Plan Year in which such
Excess Contributions were made. To the extent the Committee shall elect to do
so, such Excess Contributions and income allowable thereto may be distributed
within the first 2-1/2 months of a Plan Year to Participants on whose behalf
such Excess Contributions were made during the preceding Plan Year.

               (i) For purposes of this Article 3.8(b), and Article 3.8(c),
"Excess Contributions" shall mean the excess of:

                    (A) The aggregate amount of 401(k) Contributions contributed
on behalf of Highly Compensated Employees who were Participants during a Plan
Year, over

                    (B) The maximum amount of 401(k) Contributions permitted
under Article 3.7 for such Plan Year, which shall be determined by reducing the
amount of 401(k) Contributions contributed on behalf of Participants who were
Highly Compensated Employees during such Plan Year in order of their Deferral
Percentages, beginning with the highest of such Deferral Percentages.

               (ii) The income allocable to Excess Contributions shall be equal
to the sum of the allocable gain or loss for the Plan Year for which the Excess
Contributions were made, and the allocable gain or loss for the period between
the end of such Plan Year and the date of distribution, as determined as
follows:

                    (A) The income allocable to a Participant's Excess
Contributions for a Plan Year shall be determined by multiplying the total
income for the Plan Year allocable to the Participant's 401(k) Contributions
(including amounts treated as 401(k) Contributions) by a fraction, the numerator
of which shall be the Participant's Excess Contributions, and the denominator of
which shall be the total balance of the Participant's 401(k) Account (including
amounts treated as 401(k) Contributions) as of the end of the Plan Year, reduced
by the gain allocable to such Account for the Plan Year, and increased by the
loss allocable to such Account for the Plan Year.

                    (B) The allocable income shall include income for the period
between the end of the Plan Year for which the Excess Contributions were made,
and the date on which the corrective distribution is made to the Participant.
For purposes of calculating the allocable income for this period, the Committee,
in its sole 


                                       33
   19
discretion, shall select one of the two following methods, provided that the
method selected shall be applied on a uniform and nondiscriminatory basis for
all Participants with Excess Contributions:

                         (1) The "fractional method," under which the income for
the period between the end of the Plan Year and the last day of the month
preceding the distribution date shall be multiplied by a fraction determined
under the method described in Article 3.8(b)(ii)(A) above, or

                         (2) The " 10% method," under which 10% of the allocable
income determined pursuant to Article 3.8(b)(ii)(A) above shall be multiplied by
the number of calendar months that have elapsed between the end of the Plan Year
and the distribution date. For purposes of determining the number of calendar
months under the 10% method, a distribution made on or before the fifteenth day
of a month shall be treated as having been made on the last day of the preceding
month and a distribution occurring after the fifteenth day of a month shall be
treated as having been made on the first day of the following month.

                    (iii) For purposes of this Article 3.8(b), if the Highly
Compensated Employee's Deferral Percentage is determined by combining the 401(k)
Contributions and compensation of all Family Members pursuant to Article
3.7(c)(2), then the maximum amount of 401(k) Contributions permitted is
determined in accordance with the leveling method set forth above in Article
3.8(b)(i)(B), and the Excess Contributions for the Family Members are allocated
among the Family Members in proportion to their 401(k) Contributions.

                    (iv) The Excess Contributions which would otherwise be
distributed to a Participant pursuant to this Article 3.8 shall be reduced by
the amount of Excess Deferrals distributed to such Participant, in accordance
with regulations promulgated by the Secretary of the Treasury. (Redesignated
effective 1/1/89, Third Amendment)

                    (v) If Excess Contributions and allocable income for a Plan
Year are not corrected by distribution before the close of the first 2-1/2
months of the following Plan Year, the Employer shall be subject to a 10% excise
tax on the amount of such Excess Contributions, pursuant to section 4979 of the
Code. Such excise tax shall be due at the same time as the Employer's income tax
for its taxable year with or within which the Plan Year ends.

     3.9 Contributions Held in Trust. The amount of 401(k) Contributions
contributed by the Employer on the Participant's behalf shall be transferred to
the Trustee, or such other depository as the Committee may designate, as soon as
it is reasonable to do so and in no event later than thirty (30) days following
the close of the month in which such 401(k) Contributions were deducted from a
Participant's Compensation.

     4.1 Rollovers. Notwithstanding any other provision hereof, subject to the
consent of the Committee, the Trustee shall be authorized to accept assets from
a person who is an Eligible Employee provided the transfer of such assets to
this Plan was initiated by such Eligible Employee and qualifies as a rollover
contribution within the meaning of sections 402(c) and 408(d)(3) of the Code.
Any assets so transferred on behalf of an Eligible Employee shall be deposited
in the Trust and allocated to the Eligible Employee's Rollover Account.

     4.2 Voluntary Contributions. Effective January 1, 1990, Voluntary
Contributions made by a Participant prior to January 1, 1990 under the terms of
the Gateway Design Automation Corporation 401(k) Profit Sharing Plan shall be
held in the Participant's Voluntary Account separate from any other
contributions under the Plan and any allocable forfeitures. No additional
Voluntary Contributions shall be made to such Account or the Plan.

Company Contribution or a Profit Sharing Contribution on behalf of each
Participant described in Article 2.1 (a) and (b) such amount as shall be
determined by the Board in its sole discretion; provided, however, that in no
event shall the Employer contribute for any Plan Year an amount which, when
added to the total amount of 401 (k) Contributions and Matching Contributions,
if any, made for such Plan Year, is in excess of the amount which the Employer
will be permitted to deduct on its federal income tax return for such Plan Year
as a contribution to the Plan, in accordance with the provisions of section 404
of the Code. If the Board determines to make a Company Contribution or a Profit
Sharing Contribution for only a portion of a Plan Year. then only the
Participant's Compensation for such portion of such Plan Year shall be taken
into account.

     5.2 Payment of Contributions.

          (a) A Company Contribution, if any, for any Plan Year shall be paid in
cash by the Employer to the Trustee or such other depository as the Committee
may designate, on a quarterly basis. In such case. only the Compensation
received by the Participant during the preceding calendar quarter shall be taken
into account.

          (b) A Profit Sharing Contribution, if any, for any Plan Year may be
paid in cash by the Employer to the Trustee or such other depository as the
Committee may designate in one or more installments as the Board, it its sole
discretion, shall determine.

                             MATCHING CONTRIBUTIONS

         6.1 Authorization of Matching Contributions. If authorized by the
Board, for each matching period specified by the Board, the Employer shall
contribute an amount specified by the Board on behalf of each Participant who
has made 401(k) Contributions during such matching period and who is employed on
the last day of the matching period to each Participant's Matching Account.

         The Matching Contributions required to be made by the Employer under
this Article 6 for any Plan Year shall be reduced by the amount of forfeitures
which occurred during such Plan Year or prior Plan Years and which are not
otherwise required to be restored pursuant to Article 10.

     6.2 Actual Contribution Percentage Limitation.

          (a) In order that the Plan comply with the requirements of section
401(m) of the Code, the Matching Contributions made for each Plan Year must
satisfy one of the following tests:

               (1) The Actual Contribution Percentage for Participants who are
Highly Compensated Employees for the Plan Year shall not exceed the Actual
Contribution Percentage for Participants who are Non-Highly Compensated
Employees for the Fiscal Year multiplied by 1.25; or

               (2) The Actual Contribution Percentage for Participants who are
Highly Compensated Employees for the Plan Year shall not exceed the Actual
Contribution Percentage for Participants who are Non-Highly Compensated
Employees multiplied by 2, provided that the Actual Contribution Percentage for
Participants who are Highly Compensated Employees does not exceed the Actual
Contribution Percentage for Participants who are Non-Highly Compensated
Employees by more than 2 percentage points, or such lesser amount as the
Secretary of the Treasury shall prescribe to prevent the multiple use of this
alternate test with respect to any Highly Compensated Employee.

          (b) For purposes of this Article 6.2, the following definitions shall
apply:

               (1) "Actual Contribution Percentage" shall mean the average
(expressed as a percentage) of the Contribution Percentages of the Participants
in a group.

               (2) "Contribution Percentage" shall mean the ratio (expressed as
a percentage) that the Matching Contributions made on behalf of a Participant
during the Plan Year bears to the Participant's Compensation for such Plan Year.

          (c) For purposes of this Article 6.2, the following special rules
shall apply:

               (1) The Contribution Percentage for any Participant who is a
Highly Compensated Employee for the Plan Year and who is eligible to have
matching contributions or elective deferral contributions 


                                       36
   22
allocated to his account under two or more plans described in section 401(a) of
the Code or arrangements described in Section 401(k) of the Code that are
maintained by the Company or a Related Company shall be determined as if all
such contributions were made under a single plan or arrangement.

               (2) For purposes of determining the Contribution Percentage of a
Participant who is a Highly Compensated Employee and is either a 5% owner as
defined in 1.1(t) or one of the ten most Highly Compensated Employees of the
Company, the Matching Contributions and the Compensation of such Participant
shall include the Matching Contributions and Compensation of Family Members, and
such Family Members shall be disregarded in determining the Contribution
Percentages for Participants who are Non-Highly Compensated Employees.

               (3) A Participant's compensation shall be as defined in 1.1(j)
except that compensation shall include 401(k) Contributions to the Plan and
salary reduction contributions to any plan maintained by the Company or a
Related Company which is a cafeteria plan as defined by section 125 of the Code.

               (4) The Contribution Percentages of any Participant under two or
more arrangements described in section 401(m) of the Code that are maintained by
the Company or a Related Company shall be determined as if all Matching
Contributions were made under a single arrangement, if the arrangements are
treated as a single plan for purposes of meeting the requirements of sections
401(a)(4) and 410(b) (other than section 410(b)(2)(A)(ii)) of the Code.

               (5) As provided in, and in accordance with, the regulations
promulgated by the Secretary of the Treasury, the Committee may, in its sole
discretion, elect to take into account elective deferrals and qualified
non-elective contributions made on behalf of a Participant under the Plan or any
other plan of the Company for purposes of determining such Participant's
Contribution Percentage only if such contributions are nonforfeitable when made
and distributable only under the following circumstances:

                    (a) The Employee's retirement, death, Total Disability or
separation from service;

                    (b) The termination of the Plan without establishment of a
successor plan:

                    (c) The Employee's attainment of age 59-1/2 or, for Plan
Years beginning before 1989, the Employee's hardship:

                    (d) The sale or other disposition by the Company or a
Related Company to an unrelated corporation, which does not maintain the Plan,
of substantially all of the assets used in a trade or business, but only with
respect to employees who continue employment with the acquiring corporation; and

                                       37
   23
                    (e) The sale or other disposition by the Company or a
Related Company of its interest in a subsidiary to an unrelated entity which
does not maintain the Plan, but only with respect to Employees who continue
employment with the subsidiary. Non-elective contributions which may be treated
as Matching Contributions must satisfy these requirements without regard to
whether they are actually taken into account as Matching Contributions.

                    (f) Any distribution pursuant to subparagraphs (5)(b), (d)
or (e) of this Section 6.2(c)(5) must be a lump sum distribution (within the
meaning of section 401(k)(10)(B)) of the Participant's vested interest within
one taxable year.

               (6) The Committee shall maintain such records as are necessary to
demonstrate compliance with the requirements of Section 6.2(a) including the
extent to which elective contributions and qualified non-elective contributions
are taken into account for purposes of determining a Participant's Contribution
Percentage

               (7) The determination and treatment of the Matching Contributions
and Contribution Percentage of any Participant shall satisfy such other
requirements as may be prescribed by the Secretary of the Treasury.

     6.3 Distribution or Forfeiture of Excess Matching Contributions

          (a) Notwithstanding any other provision of the Plan, in the event
neither of the special tests described in Section 6.2 can be satisfied, then the
Excess Aggregate Contributions of certain Highly Compensated Employees for a
Plan Year shall be corrected by distribution of such Excess Aggregate
Contributions and allocable income to any Participant with Excess Aggregate
Contributions for such Plan Year. Distribution must be made, if administratively
feasible, within the first 2-1/2 months of the Plan Year following the Plan Year
for which the Excess Aggregate Contributions were made; provided, however, that
in no event shall distribution occur later than the end of the Plan Year
following the Plan Year for which the Excess Aggregate Contributions were made.
Notwithstanding any other provision in the Plan, the consent of a Participant or
his or her spouse shall not be required for a distribution of Excess Aggregate
Contributions and allocable income. Such distributions shall be in compliance
with Section 401(a)(4) of the Code.

          (b) In order to correct the Excess Aggregate Contributions of
Participants who are Highly Compensated Employees, the methods of correction
described in Section 6.3(a) must be accomplished on an Employee-by-Employee
basis. The Excess Aggregate Contributions for certain Participants who are
Highly Compensated Employees shall be reduced as follows: the first such
reduction shall be made by reducing the Contribution Percentage of the Highly
Compensated Employee with the highest Contribution Percentage to the
Contribution Percentage of the Highly Compensated Employee with the second
highest Contribution Percentage. If the requirements of Section 6.2 are not
satisfied by this first reduction. then the Contribution Percentages of the two
Highly Compensated Employees with the highest Contribution Percentages 


                                       38
   24
shall be reduced to the Contribution Percentage of the Highly Compensated
Employee with the third highest Contribution Percentage. The reduction in
Contribution Percentage shall be repeated in the same manner until the
requirements of Section 6.2 are satisfied for such Plan Year.

          (c) For purposes of this Article 6.3 and Article 22.3 hereof, "Excess
Matching Contributions" shall mean the excess of:

               (1) The aggregate amount of the Matching Contributions made on
behalf of Participants who are Highly Compensated Employees during a Plan Year,
over

               (2) The maximum amount of the Matching Contributions permitted
for such Plan Year under Article 6.2 hereof, which maximum amount shall be
determined by reducing the Matching Contributions made on behalf of Participants
who are Highly Compensated Employees during such Plan Year in order of their
Contribution Percentages, beginning with the highest of such Contribution
Percentages.

          (d) The income allocable to Excess Matching Contributions shall be
equal to the sum of the allocable gain or loss for the Plan Year for which the
Excess Matching Contributions were made, and the allocable gain or loss for the
period between the end of such Plan Year and the date of distribution or
forfeiture, determined in accordance with the method set forth in Article
3.8(b)(ii), except that "Excess Matching Contributions," "Matching
Contributions," and "Matching Contributions Account" shall be substituted for
"Excess Contributions," "401(k) Contributions," and "401(k) Account,"
respectively.

          (e) Notwithstanding any other provision of the Plan, no forfeitures
arising under this Article 6.3 shall be reallocated to the Account of any Highly
Compensated Employee.

          (f) For purposes of this Article 6.3, if the Highly Compensated
Employee's Contribution Percentage is determined by combining the Matching
Contributions and compensation of all Family Members pursuant to Article
6.2(c)(2), then the maximum amount of Matching Contributions permitted is
determined in accordance with the leveling method set forth above in Article
6.3(b)(2), and the Excess Matching Contributions for the Family Members are
allocated among the Family Members in proportion to their Matching
Contributions.

     6.4 Payment of Contributions. Matching Contributions shall be paid in cash
by the Employer to the Trustee. Matching Contributions shall be made within a
reasonable amount of time after the end of the matching period to which they
relate.

     6.5 Multiple Use of Alternative Limitation.

          (a) In order for the Plan to comply with the requirements of sections
401(k) and 401(m) of the Code, the Plan must satisfy the tests set forth in
Articles 3.7(a) and 6.2(a). However, the Employer must avoid the multiple use of
the alternative limitation as set forth in Articles 3.7(a)(2) and 6.2(a)(2) with
respect to Highly Compensated Employees.

                                       39
   25
          (b) For purposes of this Article 6.5, a multiple use of the
alternative limitation is present when all of the following conditions occur:

               (1) One or more Highly Compensated Employees of the Employer are
eligible to participate in a cash or deferred arrangement subject to section
401(k) of the Code, and in the plan maintained by the Employer subject to
section 401(m) of the Code;

               (2) The sum of the Actual Deferral Percentage of the entire group
of eligible Highly Compensated Employees under such arrangement subject to
section 401(k) of the Code and Actual Contribution Percentage of the entire
group of eligible Highly Compensated Employees under such plan subject to
section 401(m) of the Code exceeds the Aggregate Limit;

               (3) The Actual Deferral Percentage of the entire group of
eligible Highly Compensated Employees under the arrangement subject to section
401(k) of the Code exceeds 125 percent of the Actual Deferral Percentage of the
entire group of eligible Non-Highly Compensated Employees; and

               (4) The Actual Contribution Percentage of the entire group of
eligible Highly Compensated Employees under such plan subject to section 401 (m)
of the Code exceeds 125 percent of the Actual Contribution Percentage of the
entire group of eligible Non-Highly Compensated Employees.

          (c) For purposes of the this Article 6.5, the Aggregate Limit is
defined as the greater of:

               (1) The sum of:

                    (A) 125 percent of the greater of the Relevant Actual
Deferral Percentage or the Relevant Actual Contribution Percentage, and

                    (B) Two (2) percentage points plus the lesser of the
Relevant Actual Deferral Percentage or the Relevant Actual Contribution
Percentage. In no event, however, shall this amount exceed twice the lesser of
the Relevant Actual Deferral Percentage or the Relevant Actual Contribution
Percentage; or

               (2) The sum of:

                    (A) 125 percent of the lesser of the Relevant Actual
Deferral Percentage or the Relevant Actual Contribution Percentage, and

                    (B) Two (2) percentage points plus the greater of the
Relevant Actual Deferral Percentage or the Relevant Actual Contribution
Percentage. In no event, however, shall this amount exceed twice the greater of
the Relevant Actual Deferral Percentage or the Relevant Actual Contribution
Percentage.

          (d) For purposes of this Article 6.5, the term "Relevant" Actual
Deferral Percentage and term "Relevant" Actual Contribution Percentage mean the
Actual Deferral Percentage or the Actual Contribution Percentage of the eligible
group of Non-Highly Compensated Employees.

                                       40
   26
          (e) In the event a multiple use of the alternative limitation as
described in Article 6.5(b) is present, such multiple use shall be corrected by
reducing the Actual Contribution Percentage of the Highly Compensated Employees
so that the combined Actual Deferral Percentage and the Actual Contribution
Percentage does not exceed the Aggregate Limit. The required reduction shall be
treated as an Excess Matching Contribution as described in Article 6.3(b). The
method of correct to be used to reduce the Actual Contribution Percentage shall
be the method as set forth in Article 6.3(b)(2).

as it shall deem appropriate; provided, however, that such rules and procedures
shall be communicated to Participants and shall be applied in a uniform and
nondiscriminatory manner. Unless an effective investment direction is made by
the Participant, all such contributions shall be invested in a fixed
interest-type account as determined by the Committee or such other account as
determined by the Committee.

          (a) The full amount credited to a Participant's Profit Sharing Account
and MATCHING Account shall be deemed fully vested and nonforfeitable when the
Participant attains his Normal Retirement Date, or when the Participant
terminates employment by reason of death or Total Disability. Any amounts
attributable to a Participant's Matching Contributions and Profit Sharing under

          (c) For the purposes of determining a Participant's Years of Service,
all of the Participant's Service with the Employer shall be taken into account,
except that in the case of a Participant who has five consecutive One Year
Breaks in Service, Years of Service thereafter shall not be taken into account
for purposes of determining the vested portion of a Participant's Profit Sharing
Account or Matching Account which accrued before such five consecutive One Year
Breaks in Service.

     10.3 Forfeitures.

          (a) In the event a Participant terminates employment when such
Participant is less than 100% vested in his Matching Account or Profit Sharing
Account, the portion of the Participant's Accounts that is not vested shall be
allocated to a suspense account as of the date on which the Participant
terminates employment. If a former Participant is not rehired before he or she
has 5 consecutive One Year Breaks in Service. the balance in the suspense
account shall be applied as follows:

               (1) First, to reduce the Employer's Matching Contributions, if
any, for the matching periods during the Plan Year;

               (2) Next, if amounts remain in such suspense account after the
application of paragraph (1) above, to reduce the Employer's Profit Sharing
Contributions, if any, for the Plan Year; and

                                       44
   30
               (3) Next, if amounts remain in such suspense account after the
application of paragraphs (1) and (2) above, to reduce the Employer's Profit
Sharing Contributions, if any, for the Plan Year.

     If any amounts remain in such suspense account as of the end of the Plan
Year after the application of paragraphs (1), (2), and (3) above, such amounts
shall be carried forward and applied in the next succeeding Plan Year in
accordance with this subsection (a). Any such amounts remaining upon Plan
termination shall be allocated among Participants as a Profit Sharing
Contribution.

          (b) If a former Participant is reemployed before he has 5 consecutive
One Year Breaks in Service, an amount equal to the balance in the suspense
account (unadjusted for income or loss) shall be restored to the Participant's
Accounts, in accordance with the following rules:

               (1) In the event a former Participant did not receive a
distribution of the vested portion of his Accounts, the balance in the suspense
account shall be credited to the Participant's Accounts as of his reemployment
date.

               (2) In the event a former Participant received a distribution of
the vested portion of his Account(s), the balance in the suspense account shall
be maintained as a separate subaccount of the Participant's Account(s). The
vested amount of such separate subaccount shall be determined by applying the
following formula:

                      Vested amount = P(AB + (RxD)) - (RxD)

     For purposes of applying the formula, P is the vested percentage in
accordance with this Article 10 at the date of determination; AB is the Account
balance at the date of determination; D is the amount of the distribution
previously made; and R is the ratio of the Account balance at the date of
determination to the Account balance immediately following the prior
distribution. The date of determination is any date on which the Participant's
vested amount in such separate subaccount is determined.

          (c) If a former Participant is not rehired before he has 5 consecutive
One Year Breaks in Service, the balance in the suspense account shall be
forfeited permanently and applied as discussed in paragraph (a).

          (d) Such amounts as may be required under this Article 10.3 to restore
any Participant's Accounts shall be restored first from the suspense account
established pursuant to subsection (a) above, and next, to the extent necessary,
from additional contributions of the Employer for such Plan Year.

          (e) If the Plan is terminated, all rights to forfeiture restoration
shall lapse as to any former Participant who has not resumed employment before
such Plan termination unless (1) the Participant has elected pursuant to Article
12 to retain his vested interest in the Plan, and (2) the Participant has not
incurred 5 consecutive One Year Breaks in Service prior to termination.

                                     SERVICE

     11.1 Year of Service. A Participant shall be credited for each Year of
Service determined in accordance with the provisions of Articles 11.2 and 11.3.

     11.2 Service Definitions. The following words and phrases as used in
Articles 10 and 11 shall have the following meanings, unless a different meaning
is clearly required by the context:

          (a) "Hours of Service" shall mean:

               (1) Each hour for which an Employee is directly or indirectly
paid or entitled to payment by the Company or a Related Company for the
performance of duties during the applicable computation period. These hours
shall be credited to the Employee for the Plan Year or computation period in
which the duties are performed.

               (2) Each hour for which an Employee is directly or indirectly
paid or entitled to payment by the Company or a Related Company on account of a
period of time during which no duties are performed (irrespective of whether the
employment relationship has terminated) due to vacation, holiday, sickness,
incapacity (including disability), leaves of absence, layoff, jury duty, or
military service. Payments made or due under a plan maintained by the Company or
a Related Company solely for the purpose of complying with applicable worker's
compensation, unemployment compensation or disability insurance laws, or to
reimburse the Employee for medical or medically related expenses shall not be
considered as payments by the Company or Related Company for purposes of this
Article 11.2. Notwithstanding the foregoing, however, no more than 501 Hours of
Service shall be credited to an Employee on account of any single continuous
period in which the Employee performs no duties. The number of Hours of Service
for which no duties are performed and the computation period to which they
relate shall be determined in accordance with the Department of Labor
Regulations section 2530.200b-2(b) and (c) or similar superseding regulations.

               (3) Each hour for which back pay, irrespective of mitigation of
damages, has been either awarded or agreed to by the Company or a Related
Company. The number of hours for which back pay is attributable shall be
determined in accordance with Department of Labor Regulations section
2530.200b-2(b). These hours shall be credited to the Employee for the Plan Year
or computation period in which the award, agreement, or payment pertains, rather
than the Plan Year or computation period in which the award, agreement, or
payment is made. No hours shall be credited under this subparagraph (3) if the
same hours have been credited under subparagraphs (I) or (2) above.

                                       46
   32
               (4) Except as otherwise provided in this Article 11.2, for all
purposes of determining Hours of Service under the Plan, each Employee shall be
credited with actual Hours of Service.

          (b) "One Year Break in Service" shall mean a Plan Year during which a
Participant is credited with 500 Hours of Service or less. For all purposes
hereunder, a One Year Break in Service shall be deemed to have occurred as of
the last day of the Plan Year in which such One Year Break in Service occurred.
If an Employee is absent from work for any period by reason of (A) pregnancy of
the Employee, (B) the birth of a child of the Employee, (C) the placement of a
child with the Employee, in connection with the adoption of such child by such
Employee, or (D) care provided for such child by the Employee for a period
beginning immediately following such birth or placement, the Employee shall not
be treated as having incurred a One Year Break in Service in the Plan Year in
which such absence begins. However, if the Employee would not otherwise have
suffered a One Year Break in Service during the Plan Year in which the absence
begins, the Employee shall not be treated as having incurred a One Year Break in
Service in the immediately following Plan Year. The Administrative Committee may
require, as a condition of receiving such maternity or paternity leave credit,
that such Employee furnish timely information to establish that the absence from
work is for reasons referred to above and to establish the number of days for
which there was such an absence.

          (c) "Year of Service" shall mean a Plan Year during which an Employee
is credited with not less than 1,000 Hours of Service.

Valid Logic Systems Savings and Retirement Plan at the time of the merger of the
two Plans.

                    DISTRIBUTION OF BENEFITS UPON TERMINATION

     12.1 Methods of Payment of Distributions.

          (a) When a Participant terminates employment, the balance in the
Participant's Accounts shall be distributed in one of the following methods, as
selected by the Participant:

               (1) In cash in a single distribution of the entire balance then
standing in the Participant's Accounts; or

               (2) Payments in installments as nearly equal as possible over a
period of 5, 10 or 15 years, but in no event over a period exceeding the
Participant's life expectancy or the joint life expectancy of the Participant
and his or her designated Beneficiary. In no event shall the present value of
any installment payments to be paid to the Participant be less than fifty
percent (50%) of the present value of the payments to be made to the Participant
and his Beneficiaries.

               (3) Effective January 1, 1990, with respect only to Participants
who were participants in the Gateway Design Automation Corporation 401(k) Plan
which was merged into this Plan, in an annuity form of benefit. If a Participant
elects such annuity form of benefit pursuant to this subparagraph, his
distribution shall be made pursuant to Article 12.6. The annuity form of benefit
shall not be available if the value of the Participant's vested Accounts is not
in excess of $3,500 (and at the time of any prior distribution had not exceeded
$3,500).

     If the Participant does not select a method of payment pursuant to this
Article 12.1, payment shall be made in one lump sum.

     If a Participant has elected to receive benefit payments in installments,
such Participant may thereafter elect to receive the remaining balance of his
Accounts in a single distribution.

                                       48
   34
          (b) If distribution of a Participant's benefit commences and the
Participant dies before his entire benefit has been distributed to him, the
remaining portion of his benefit shall be distributed in accordance with the
distribution method being utilized on the date of his death. If a Participant
dies before benefit payments commence, then the Employer shall distribute such
Participant's Accounts to the Participant's Beneficiary in cash in a single lump
sum as soon as is administratively feasible, provided such distribution shall be
made within five (5) years after the date of death of such Participant.
Notwithstanding the foregoing, however, if the Participant has in effect a
distribution election providing for payment of benefits to a Beneficiary in
installments not exceeding the life expectancy of the Beneficiary, and further
providing that distributions are to commence not later than one (1) year after
the date of the Participant's death, the benefits shall be distributed as
provided in such election.

     12.2 Amounts Available for Distribution. The value of the Participant's
Accounts shall be determined based on the Valuation Date coincident with or next
following the Participant's termination of employment.

     12.3 Timing of Payment of Distributions.

          (a) Distribution of the balance then standing in the Participant's
Accounts shall be made or commenced as soon as administratively feasible after
the value of such Participant's Accounts is determined pursuant to Article 12.2,
except that if the value of the Participant's Account exceeds $3,500 (or at the
time of any prior distribution exceeded $3,500) no distribution shall be made
prior to the Participant's Normal Retirement Date without the prior written
consent of the Participant and, when applicable, the Participant's spouse.

          (b) Notwithstanding any other provision of the Plan, distribution of
the vested amount credited to a Participant's Account shall be made or commenced
no later than the 60th day after the close of the Plan Year in which the latest
of the following events occur:

               (1) The Participant's Normal Retirement Date;

               (2) The 10th anniversary of Participant's commencement of
participation in the plan; or

               (3) The Participant's termination of employment with the Company.

          (c) Notwithstanding any other provision herein to the contrary,
benefit payments shall begin by the April 1 immediately following the end of the
calendar year in which the Participant attains age 70-1/2 years, whether or not
he or she is an Employee. Any distribution made or commenced under this Section
12.3(c) shall, beginning with the year in which the Participant attains age
70-1/2, be not less than the quotient obtained by dividing (1) the Participant's
vested Account balance as of the last Valuation Date of the preceding year by
(2) the applicable divisor as determined under the incidental benefit
requirement of Code section 401(a)(9).

          (d) The Participant's payment election must be consistent with the
requirement of Code section 401(a)(9) that all payments are to be completed
within a period not to exceed the lives or the joint and last survivor life
expectancy of the Participant and his or her Beneficiary. The life expectancies
of a Participant and his or her 


                                       49
   35
Beneficiary may not be recomputed manually.

          (e) Payment to a Beneficiary must either:

               (1) be completed by the end of the calendar year that contains
the fifth anniversary of the Participant's death or

               (2) begin by the end of the calendar year that contains the first
anniversary of the Participant's death and be completed within the period of the
Beneficiary's life or life expectancy, except that:

                    (i) If the Participant dies after the April 1 immediately
following the end of the calendar year in which he or she attains age 70-1/2,
payment to his or her beneficiary must be made at least as rapidly as provided
in the Participant's distribution election:

                    (ii) If the surviving spouse is the Beneficiary, payments
need not begin until the end of the calendar year in which the Participant would
have attained age 70-1/2 and must be completed within the spouse's life or life
expectancy; and

                    (iii) If the Participant and the surviving spouse who is the
Beneficiary die (A) before the April 1 immediately following the end of the
calendar year in which the Participant would have attained age 70-1/2 and (B)
before payments have begun to the spouse, the spouse shall be treated as the
Participant in applying these rules.

          (f) If the amount of a required distribution cannot be ascertained by
the date the distribution is to be made, or it is not possible to make such
distribution because the Committee has been unable to locate the Participant
after making reasonable efforts to do so, a distribution retroactive to the
required commencement date may be made no later than 60 days after the earliest
date on which the amount of such distribution can be ascertained under the Plan
or the date on which the Participant is located, whichever is applicable.

     12.4 Deferred Distributions. When the distribution to a terminated
Participant is deferred because such terminated Participant does not consent to
an early distribution as required by Article 12.3, then such terminated
Participant's Accounts shall be invested in accordance with the Participant's
investment option under the Plan. Except as provided in Article 13.1, no
terminated Participant shall be eligible for a loan pursuant to Article 13 or a
financial hardship withdrawal in accordance with Article 14.1.

     12.5 No Liability. Any payment to a Participant, or to his legal
representative or Beneficiary, in accordance with the provisions of the Plan,
shall be in full satisfaction of all claims hereunder against the Trustee, the
Committee and the Employer, any of whom may require such Participant, legal
representative or Beneficiary as a condition precedent to such payment to
execute a receipt therefor in such form as shall be determined by the Trustee,
the Committee or the Employer, as the case may be. The Employer does not
guarantee the Trust, the Participants, or their legal representatives or
Beneficiaries against loss of or depreciation in value of any right or benefit
that any of them may 


                                       50
   36
acquire under the terms of this Plan. All of the benefits payable hereunder
shall be paid or provided for solely from the Trust, and the Employer assumes no
liability or responsibility therefor.

     12.6 Payment of Benefit in the Form of Annuities. Effective January 1,
1990, if a Participant elects an annuity form of benefit pursuant to Article
12.1 (a)(3), the benefits provided by the Plan shall be distributed as follows:

          (a) (1) Married Participants. The benefits under the Plan for a
Participant who is married on the date the benefit payments commence, shall be
in the form of a qualified joint and survivor annuity, payable in equal monthly
installments, commencing on the Participant's Normal Retirement Date, or such
earlier date as the Participant may elect which is after such Participants'
termination of employment, for the life of the Participant with a survivor
annuity for the life of the spouse which is fifty percent (50%) of the amount of
the annuity payable during the joint lives of the Participant and the
Participant's spouse. This qualified joint and survivor annuity shall be the
Actuarial Equivalent of the value of the Participant's vested Accounts
determined as of the Valuation Date coinciding with or next following the
Participant's termination of employment. For purposes of this Section 12.6, any
marriage requirement for the Participant and his or her spouse is limited to the
one-year period ending on the date the benefit payments commence. The Plan will
treat a Participant and his or her spouse who are married on the date benefit
payments commence as having been married during the one-year period ending on
that date provided they remain married for one year. Notwithstanding, if the
Participant and his or her spouse do not remain married for one year, the spouse
loses any survivor benefit rights and any amount paid to the Participant will
not be retroactively corrected. For purposes of this Section 12.6, "Actuarial
Equivalent" shall mean a payment or series of payments mathematically equivalent
to another amount based on consistently applied reasonable actuarial assumptions
selected by the Employer, if such assumptions do not result in discrimination in
favor of Employees who are Highly Compensated Employees.

               (2) Unmarried Participants. If a Participant has not been married
for at least one year on the date benefit payments commence, and does not have a
former spouse or spouses who is/are entitled to survivor annuity benefits under
a qualified domestic relations order as provided in Article 22.4 the benefits
under the Plan for such Participant shall be in the form of a life annuity,
payable in equal monthly installments, commencing on the Participants' Normal
Retirement Date, or such earlier date after termination of employment as the
Participant may elect, for the life of the Participant. This life annuity shall
be the Actuarial Equivalent of the value of the Participants' vested Accounts
determined as of the Valuation Date coinciding with or next following the
Participants' termination of employment. Any Participant who has elected an
annuity form of benefit, may at any time prior to the annuity starting date,
revoke such election and elect to have benefits paid in one of the options set
forth in Article 12.1(a), subject, however, to the provisions of Article
12.6(c).

                                       51
   37
          (b) Death Benefits. Upon the death of a Participant who has elected an
annuity form of benefit pursuant to Article 12.1(a)(1), his or her Beneficiary
shall be entitled to receive a death benefit determined as follows:

               (1) The death benefits, if any, payable upon the death of any
Participant who is receiving (or has received) retirement benefits under the
Plan will depend upon whether the particular form of annuity which such
Participant is receiving (e.g., life annuity or joint and survivor annuity)
provides for any survivor or other death benefits and shall be paid in
accordance with the form of benefit which such Participant had been receiving.

               (2) If a Participant who has not begun to receive payments under
the Plan either dies while in active service of the Employer, or separates from
service with vested benefits and thereafter dies before the annuity starting
date, the surviving spouse, if any, and the Beneficiary of the Participant shall
be entitled to a death benefit determined as follows:

                    (A) If the Participant has been married for at least one (1)
year at the time of his death, the Participant's surviving spouse shall be
entitled to a qualified preretirement survivor annuity for the life of such
surviving spouse which annuity shall be the Actuarial Equivalent of the amount
equal to the value of fifty percent (50%) of the deceased Participant's vested
Accounts as of the date of such Participant's death. Notwithstanding the
foregoing however, the surviving spouse of a deceased Participant may elect, in
lieu of receiving the qualified preretirement survivor annuity, to have fifty
percent (50%) of the Participant's vested Accounts paid in one of the options as
set forth in Article 12.1 (a). Any such election shall comply with the
requirements of Article 12.6(c).

                    (B) A death benefit will be paid to the Participant's
Beneficiary in an amount equal to the Participant's vested benefits at the time
of the Participant's death reduced by any amount payable to a surviving spouse
pursuant to Article 12.6(b)(2)(A), above. The Beneficiary may elect, with
respect to any death benefit paid pursuant to this provision, that the benefit
be paid in one of the options as set forth in Article 12.1 (a).

          (c) Revocation of Election. A Participant who has elected an annuity
form of benefit and the spouse or former spouse of a deceased Participant who is
entitled to a qualified preretirement survivor annuity, may elect to have
benefits paid in one of the options set forth in Article 12.1(a), subject to the
provisions of this Article 12.6(c).

               (1) The election to waive the qualified joint and survivor
annuity must be made within the 90-day period ending on the annuity starting
date.

               (2) The election by the Participant to waive the qualified
preretirement survivor annuity may be made or revoked at any time after the
first day of the Plan Year in which 


                                       52
   38
the Participant attains age 35 years, but it shall become irrevocable on the
Participant's death.

               (3) The election by the Participant's spouse to waive the
qualified preretirement survivor annuity may be made any time prior to the
annuity starting date.

               (4) Any waiver of a qualified joint and survivor annuity or a
qualified preretirement survivor annuity shall not be effective unless: (i) the
Participant's spouse consents in writing to the waiver; (ii) the election
designates a specific beneficiary, including any class of beneficiaries or any
contingent beneficiaries, which may not be changed without spousal consent (or
the spouse expressly permits designations by the Participant without any further
spousal consent); (iii) the spouse's consent acknowledges the effect of the
election; and (iv) the spouse's consent is witnessed by a representative of the
Plan or a notary public. Additionally, a Participant's waiver of a qualified
joint and survivor annuity shall not be effective unless the election designates
a form of benefit which may not be changed without spousal consent (or the
spouse expressly permits designations by the Participant without any further
spousal consent). The spousal consent requirement may be waived by the Committee
if there is no spouse or the spouse cannot be located, or for such other reasons
authorized in applicable Treasury Regulations.

               (5) Any consent by a spouse obtained under Article 12.6(c)(4) (or
establishment that the consent of a spouse may not be obtained) shall be
effective only with respect to such spouse. A consent that permits designations
by the Participant without any requirement of further consent by such spouse
must acknowledge that the spouse has the right to limit consent to a specific
beneficiary, and a specific form of benefit where applicable, and that the
spouse voluntarily elects to relinquish either or both of such rights.

               (6) The Committee shall furnish each Participant with an
explanation of the Plan's qualified joint and survivor annuity provisions, the
Participant's rights to waive such qualified joint and survivor annuity, the
effect of such waiver, a general description of the eligibility conditions and
other material features of the optional forms of benefit and sufficient
additional information to explain the relative values of the optional forms of
benefit available under the Plan, the right of a Participant's spouse to consent
to such waiver, and the right to make, and the effect of a revocation of waiver.
This explanation shall be furnished no less than 30 days and no more than 90
days prior to the annuity starting date and in the manner required under
applicable Treasury Regulations.

               (7) The Committee shall furnish each Participant with an
explanation of the qualified preretirement survivor annuity, the Participant's
right to waive such qualified preretirement survivor annuity, the requirement
that the Participant's spouse consent to any such waiver, and the right to make,
and the effect of, a revocation of such waiver. This explanation shall be
furnished to the Participant within the applicable period with respect to a
Participant, whichever of the following periods ends last: (i) the period
beginning on the first day of the Plan Year in which the Participant attains age
32 years and ending on the last day of the Plan Year preceding the Plan Year in
which the Participant attains age 35 years, (ii) a reasonable period after 


                                       53
   39
the individual becomes a Participant, (iii) a reasonable period ending after the
qualified preretirement survivor annuity is no longer fully subsidized, (iv) a
reasonable period ending after section 401(a)(11) of the Code first applies to
the Participant, and (v) a reasonable period after separation from service in
case of a Participant who separates before attaining age 35. For purposes of
applying (ii), (iii) and (iv), a reasonable period is the one-year period ending
after the date the applicable event occurs and the applicable period of such
events begins one year prior to the occurrence of the enumerated events. For
purposes of applying (v), the applicable period means the period beginning one
year before the separation from service and ending one year after such
separation.

          (d) Provision of Annuity Benefits Through Commercial Annuity. The Plan
may provide the annuity and qualified preretirement survivor annuity benefits
provided under this Article 12.6 through the purchase of an annuity contract
which provides such benefits and which is owned by the Plan or distributed to
the Participant, provided that such contract shall provide for the notice,
election and consent provisions applicable to such benefits which are set forth
in this Article 12.6 and Sections 401(a)(11) and 417 of the Code.

     12.7 Direct Rollover of Eligible Rollover Distributions.

          A. This section 12.7 applies to distributions made on or after January
1, 1993. Notwithstanding any provision of the Plan to the contrary that would
otherwise limit a Distributee's election under this section 12.7, a Distributee
may elect, at the time and in the manner prescribed by the Administrator, to
have any portion of an Eligible Rollover Distribution paid directly to an
Eligible Retirement Plan specified by the Distributee in a Direct Rollover.

          B. Definitions.

               (1) Eligible Rollover Distribution. An Eligible Rollover
Distribution is any distribution of all or any portion of the balance to the
credit of the Distributee, except that an Eligible Rollover Distribution does
not include: any distribution that is one of a series of substantially equal
periodic payments (not less frequently than annually) made for the life (or life
expectancy) of the Distributee or the joint lives (or joint life expectancies)
of the Distributee and the Distributee's designated beneficiary, or for a
specified period of ten years or more; any distribution to the extent such
distribution is required under section 401(a)(9) of the Code; and the portion of
any distribution that is not includable in gross income (determined without
regard to the exclusion for net unrealized appreciation with respect to employer
securities).

               (2) Eligible Retirement Plan. An Eligible Retirement Plan is an
individual retirement account described in section 408(a) of the Code, an
individual retirement annuity described in section 408(b) of the Code, an
annuity plan described in section 403(a) of the Code, or a qualified trust
described in section 401(a) of the Code, that accepts the Distributors Eligible
Rollover Distribution. However, in the case of an Eligible Rollover Distribution
to the surviving spouse, an Eligible Retirement Plan is an individual retirement
account or retirement annuity.

   40
               (3) Distributed A Distributee includes an Employee or former

Regulation 1.411(a)-11(c) is given, provided that:

          A. The Administrator clearly informs the Participant that the
Participant has a right to a period of at least 30 days after receiving the

     13.1 Requirements. Effective as of October 19, 1989, and upon written
application, the Committee may direct the Trustee to make a loan or loans to a
Participant or a former Participant or beneficiary who is a "party in interest"
within the meaning of Section 3(14) of ERISA and who has not received the entire
amount of his or her vested benefit, in accordance with the following rules:

          (a) The principal amount of a loan shall not exceed the lesser of
either paragraph (1) or (2) below:

               (1) $50,000, reduced by the Participant's highest outstanding
loan balance during the one (1) year period ending on the day before the day on
which the current loan is made. For purposes of determining the Participant's
highest outstanding loan balance, all loans made to the Participant from the
Plan and any other qualified plan maintained by the Company or a Related Company
shall be aggregated.

               (2) 50% of the Participant's vested interest in his Accounts,
reduced in either case by the current outstanding balance of all other loans to
the Participant from the Plan and any other qualified plan maintained by the
Company or a Related Company.


                                       55
   41
          (b) Loans shall be made available to all Participants on a reasonably
equivalent basis.

          (c) Loans must be secured by the Participant's vested interest in his
Accounts.

          (d) Loans must be evidenced by the borrowing Participant's promissory
note for a fixed term not to exceed five (5) years unless the proceeds of the
loan are used to acquire any dwelling unit which within a reasonable time is to
be used (determined at the time the loan is made) as a principal residence of
the Participant, in which case such loan must be required to be repaid within
ten (10) years (thirty (30) years for principal residence loans made prior to
June 1, 1990). Loans for the acquisition of the Participant's principal
residence are referred to herein as Residence Loans and all other loans are to
be referred to as General Loans.

          (e) A loan shall bear a reasonable rate of interest and require
regular, periodic repayment through substantially level amortization and
payments not less frequently than quarterly over the life of the loan.

          (f) A loan shall not be made if such loan would constitute a
prohibited transaction under the applicable sections of ERISA and the Code, and
the regulations promulgated thereunder.

          (g) Effective September 1, 1991, a Participant may not have more than
two loans outstanding from the Plan at any time.

          (h) Loans shall be for the minimum amount of Five Hundred Dollars
($500.00).

          (i) Loans may be prepaid in full without penalty. No partial payment
is permitted.

          (j) Repayment of all loans shall be through payroll deduction, unless
the Participant is on an unpaid leave of absence or on disability leave or has
terminated employment with the Employer, in which case repayment of the loan may
be made by personal check. A Participant may not terminate his payroll deduction
authorization. All loans made on or after June 15, 1995 shall be due and payable
in full upon termination of employment. Loans prior to June 15, 1995 may
continue to be repaid in accordance with the terms of such loans.

          (k) Loans may be immediately due and payable, in the sole discretion
of the Committee, if the Participant fails to make any installment payment when
due.

          (l) In the event of default by a Participant, such Participant's
Accounts may be offset by the outstanding loan balance at the time the
Participant becomes entitled to a distribution from the Plan.

          (m) Loans shall not be made available to Highly Compensated Employees
in an amount greater than the amount made available to other Employees.

          (n) Loans must be made in accordance with such other guidelines and
policies as shall be adopted from time to time by the Committee which, upon
adoption, shall constitute part of the Plan and which shall include such
provisions as may be required by final regulations promulgated by the Department
of Labor.

     13.2 Source of Funds. Application of Payments. The principal borrowed by
the Participant shall be funded first from the Participant's Voluntary Account,
then from the Participant's Rollover Account, then from the Participant's
Company Contribution Account, then from the Participant's Profit Sharing
Account, then from the 


                                       56
   42
Participant's Matching Account, and then from the Participant's 401 (k) Account.
No loans may be funded from a Participant's Profit Sharing Account or Matching
Account, unless the total amounts credited to such Accounts are one hundred
percent (100%) vested. Such loan shall be withdrawn pro rata from the investment
funds in which the Participant has invested his Accounts, and all interest and
principal payments on such loans shall be deposited in the investment funds in
which the Participant is investing his or her 401(k) in effect at the time of
such deposit, or in such other investment fund as the Committee may specify from
time to time. All outstanding loans shall be considered a directed investment of
the Participant and any interest shall be credited only to the Participant's
Account.

                     IN-SERVICE WITHDRAWALS BY PARTICIPANTS

     14.1 Withdrawals for Financial Hardship.

          (a) Upon written consent of the Committee, a Participant may withdraw
an amount up to one hundred percent (100%) of the vested account balance
credited to his Accounts (as of the last Valuation Date for which valuation is
available at the time of such financial hardship withdrawal, less subsequent
distributions and outstanding loans) as may be required to meet urgent and heavy
financial needs of the Participant, provided that the entire amount requested by
the Participant is not reasonably available from other resources of the
Participant. Notwithstanding the foregoing:

               (i) No earnings credited to the Participant's 401(k) Account
after December 31, 1988, may be withdrawn; and

               (ii) No terminated Participant shall be eligible for a financial
hardship withdrawal.

          (b) A financial hardship distribution will be made only for one of the
following reasons:

               (i) Expenses for medical care described in section 213(d) of the
Code previously incurred by the Participant, the Participant's spouse, or
dependents of the Participant (as defined in section 152 of the Code) or
necessary for such persons to obtain medical care described in section 213(d) of
the Code;

               (ii) Costs directly related to the purchase (excluding mortgage
payments) of a principal residence for the Participant;

               (iii) Payment of tuition and related educational fees for the
next twelve (12) months of post-secondary education of the Participant, his
spouse, children or dependents (as defined in section 152 of the Code);

                                       57
   43
               (iv) Payments necessary to prevent the Participant's eviction
from his principal residence or foreclosure on mortgage of the Participant's
principal residence; or

               (v) Such other reason as the Secretary of the Treasury may
prescribe.

          (c) The amount of the withdrawal must not exceed the amount required
to relieve the financial need created by the hardship (including any amounts
necessary to pay any income taxes or penalties reasonably anticipated to result
from the withdrawal) after taking into account other resources that are
reasonably available to the Participant for this purpose.

          (d) Amounts attributable to Matching Contributions and qualified
non-elective contributions that are used pursuant to Section 3.7(c)(4) of the
Plan to determine the Participant's Deferral Percentage for any Plan Year may
not be withdrawn on account of financial hardship.

          (e) No earnings credited to a Participant's 401(k) Account after
December 31, 1988, may be withdrawn.

          (f) If the Plan permits an annuity form of benefit subject to section
12.1(a)(3), the Participant must waive the option of receiving the portion of
his vested benefits being distributed as an in-service withdrawal in the form of
an annuity and his or her spouse (if applicable) must consent to the waiver and
the election to receive the in-service withdrawal in the form of a lump sum
payment.

          (g) The Participant must certify that the financial need cannot be
relieved:

               (i) Through reimbursement or compensation by insurance or
otherwise;

               (ii) By reasonable liquidation of the Participant's assets, to
the extent such liquidation would not itself cause an immediate and heavy
financial need;

               (iii) By discontinuing the Participant's 401(k) Contributions to
the Plan; or

               (iv) By other distributions or non-taxable (at the time of the
loan) loans from plans maintained by the Employer or any other Employer, or by
borrowing from commercial sources on reasonable commercial terms.

          (h) Financial hardship withdrawals shall first be made from a
Participant's Voluntary Account, then from the Participant's Rollover Account,
then from the Participant's Company Contribution Account, then from the
Participant's Profit Sharing Account, then from the Participant's Matching
Account, and then from the Participant's 401(k) Account. No financial hardship
withdrawals may be made from a Participant's Profit Sharing Account or Matching
Account, unless the total amounts credited to such Accounts are one hundred
percent (100%) vested. The amount of the financial hardship withdrawal shall be
withdrawn pro rata from the investment funds in which the Participant has
invested his Accounts as directed by the Participant.

     14.2 Withdrawal After Age 59-1/2. After attaining age 59-1/2 years, a
Participant may withdraw such amount, up to the vested account balance credited
to his Accounts, as the Participant may request. No Participant shall be
permitted to make more than one withdrawal in any Plan Year pursuant to this
Article 14.2.

                                  BENEFICIARIES

     15.1 Beneficiary Designation. Subject to the provisions of Articles 15.1
and 15.3, each Participant shall have the right to designate on forms provided
by the Employer a Beneficiary or Beneficiaries to receive the benefits herein
provided in the event of his death, and shall have the right at any time to
revoke such designation or to substitute another such Beneficiary or
Beneficiaries. If a Participant has been married at the date of his death and
has designated a Beneficiary or Beneficiaries other than the Participant's
spouse to receive any portion of the benefits herein provided in the event of
his death, such designation shall be invalid unless and until (a) the
Participant's spouse consents in writing to such designation, (b) such consent
acknowledges the effect of such designation, and (c) such consent is witnessed
by a Notary Public or a Plan representative. Once such consent is given, it may
not be revoked and the Participant may not change his beneficiary designation
(except to name his spouse as the sole Beneficiary) without a new consent by the
Participant's spouse, which new consent must also meet the above requirements.

     15.2 Absence of Valid Designation. If, upon the death of a Participant,
former Participant or Beneficiary, there is no valid designation of Beneficiary
on file with the Employer, the Committee shall designate as the Beneficiary, in
order of priority: (a) The surviving spouse; (b) Surviving children, including
adopted children; (c) Surviving parents; or (d) The Participant's estate;
provided, however, that at all times the Committee shall have the right to
designate as Beneficiary the Participant's estate irrespective of said order of
priority. The determination of the Committee as to which persons, if any,
qualify within the aforementioned categories shall be final and conclusive upon
all persons.

     15.3 Surviving Spouse Beneficiary. Notwithstanding any other provision in
the Plan, if a Participant or former Participant dies leaving a surviving
spouse, and if such spouse had been married to the Participant throughout the
three-month period ending on the date of the Participant's death, such surviving
spouse shall be the Beneficiary for all purposes under the Plan unless the
Participant previously designated another or an additional Beneficiary, and such
surviving spouse consented to such designation in accordance with the provisions
of Article 15.1, above.

have the authority to manage and control the operation and administration of the
Plan and to control and manage the Plan assets. The Committee shall have the
authority to interpret the provisions of the Plan in its sole discretion and the
Committee's interpretations shall be binding upon all persons having an interest
in the Plan. The Committee shall consist of not fewer than four (4) persons,
with the specific number to be as specified by the Board from time to time.

     16.2 Powers of Plan Administrator. The Committee shall have complete
control of the administration of the Plan herein set forth with all powers

hereunder, including determination of eligibility of Employees, amounts of
credits, allocation of assets, method of payment, whether distributions from the
Trust shall be made in cash or in kind and the assets to be distributed, and
participation and benefits under the terms of this Plan. The Committee shall
also establish reasonable rules and procedures which shall be applied in a
uniform and nondiscriminatory manner for enrollment in the Plan and to changes
by Participants on their rules of contribution and investment options. The
Committee shall establish the rules and procedures by which the Committee will
operate. Decisions of the Committee made in good faith upon any matter within
the scope of its authority shall be final, conclusive and binding upon all
persons, including Participants and their legal representatives or
Beneficiaries; but the Committee shall at all times, in giving effect to its
decisions, act without discrimination in favor of or against any Participant,
legal representative or Beneficiary.

     16.3 Investment Managers. The Committee may appoint one or more Investment
Managers to direct the investment and management of all or part of the assets of
the Trust. Each Investment Manager shall have the power to manage, acquire. and

Committee may revoke the appointment of any Investment Manager by giving written
notice to such Investment Manager.

     16.4 Other Agents. The Committee may employ such persons or organizations

consultants.

     16.5 Fiduciaries. Any person or group of persons may serve in more than one
fiduciary capacity with respect to the Plan.

     16.6 Indemnification. The Company shall indemnify and hold harmless the
members of the Board, the Committee and any other Employees to whom any
fiduciary responsibility with respect to the Plan is allocated or 


                                       60
   46

including attorneys' fees, incurred by such persons as a result of any act, or
omission to act, in connection with the performance of their duties,
responsibilities and obligations under the Plan and under ERISA, other than such
liabilities, costs and expenses as may result from the bad faith or criminal
acts of such persons or to the extent such indemnification is specifically
prohibited by ERISA. The Company shall have the obligation to conduct the
defense of such persons in any proceeding to which this Article 16.6 applies. If
any member of the Board, the Committee or any Employee covered by this
indemnification clause of this Article 16.6 determines that the defense of the
Company is inadequate, that member shall be entitled to retain separate legal
counsel for his or her defense and the Company shall be obligated to pay for all
reasonable legal fees and other court costs incurred in the course of such
defense unless a court of competent jurisdiction finds such person has acted in
bad faith or engaged in criminal acts. The Company may satisfy its obligation
under this Article 16.6 in whole or in part, through the purchase of a policy or
policies of insurance, but no insurer shall have any rights against the Company
arising out of this Article 16.6.

     16.7 Costs. Effective April 1, 1994, all quarterly fees associated with the
administration of the Plan and the Trust may be borne by the Plan itself, except
the following:

          (a) Any new loan set-up fee, loan prepayment fee or special loan
processing fee that is charged to the Plan in association with processing a
loan. These fees will be charged to the individual Participant for which this
service is being performed; and

          (b) A maintenance fee of $100 shall be charged to any former
Participants having an Account under the Plan on the July 1 following the
anniversary of the Participant's termination.

     Contributions made by the Employer and all other assets of the Plan shall
be held in Trust in accordance with the provisions of the Trust Agreement. All
benefits payable under the Plan shall be paid as provided for solely from the

                                   ARTICLE 18
                            AMENDMENT AND TERMINATION

     18.1 Amendment. The Employer reserves the right at any time or times to
amend the Plan by action of the Board to any extent and in any manner that the
Employer may deem advisable. Upon adoption of the resolution of the Board, the
Plan and Trust Agreement shall be deemed to have been amended in the manner set
forth therein, and the Employer, the Trustee, and all Participants, their
Beneficiaries and all other persons having any interest hereunder shall be bound
thereby. By action of the Board, the Employer may delegate to the Committee the
right to amend the Plan in such respects as the Employer shall deem advisable.
The Employer or Committee shall notify the Trustee of any such amendment to the
Plan. Such power includes the right, without limitation, to make retroactive
amendments referred to in section 401(b) of the Code (as amended by section 1023
of ERISA). However, except as provided in Article 18.3, no amendment:

          (a) Shall cause or permit any part of the principal or income of the
Trust to revert to the Employer or to be used for, or to be diverted to, any
purpose other than the exclusive benefit of Participants and their
Beneficiaries, except that

               (i) A 401(k) Contribution, made by the Employer by a mistake of
fact, shall be returned to the Employer within one year after the payment of
such contribution to the extent permitted by section 403(c) of ERISA. A 401(k)
Contribution, or a portion thereof, returned to the Employer pursuant to this
Article 18.1 (a)(i) shall be returned to the Employee from whose Compensation
the amount was withheld, as soon as administratively feasible, but in no event
later than thirty (30) days after the return of such contribution to the
Employer.

               (ii) If an Employer contribution is conditioned upon the
deductibility of the contribution under Section 404 of the Code or any successor
provision thereto, then to the extent such contribution is disallowed, this
paragraph shall not prohibit the return to the Employer of such contribution (to
the extent disallowed) within one (1) year after such disallowance of the
deduction. A 401(k) Contribution, or a portion thereof, returned to the Employer
pursuant to this Article 18.1(a)(ii) shall be returned to the Employee from
whose 


                                       62
   48

in no event later than thirty (30) days after the return of such contribution to
the Employer.

          (b) Shall change the duties or liabilities of the Trustee, or an
Investment Manager appointed pursuant to Article 16.3 of the Plan, without its
written assent to such amendment.

          (c) Shall retroactively reduce the benefits of any Participant or his
Beneficiary accrued under the Plan by reason of contributions made by the
Employer prior to the amendment except to the extent that such reduction is
permitted by ERISA.

     18.2 Termination. The Employer has established the Plan with the bona fide
intention and expectation that the Plan will continue indefinitely and that it
will be able to make its contributions indefinitely, but the Employer shall be
under no obligation to continue its contributions or to maintain the Plan for
any given length of time and may, in its sole and absolute discretion,
discontinue its contributions or terminate the Plan in whole or in part at any
time without any liability whatsoever. Notwithstanding any other provisions of
the Plan, in the event of the complete or partial termination of the Plan or
complete discontinuance of further contributions hereunder, the full value of
the Accounts of all Participants shall become fully vested and nonforfeitable.

     18.3 Employer Contributions Contingent. Notwithstanding any other provision
of the Plan or Trust to the contrary, it is specifically understood that the
Employer's obligation to make contributions hereunder are conditioned upon the
Employer receiving an initial notification from the United States Treasury
Department, Internal Revenue Service that this Plan is considered as being a
qualified plan under section 401(a) of the Code and that this Trust is
considered exempt from taxation under section 501(a) of the Code. If such
initial notification is not received, the Employer shall, at the Employer's
request, be entitled to recover from the Trustee the full amount of the then
value of such respective contributions. Prior to receipt of such notification,
no Participant hereunder or his legal representative or Beneficiary shall have
any vested interest in or be entitled to any benefit payments based on Employer
contributions made hereunder; provided, however, that upon receipt of such
notification, such vested interests or entitlements shall be retroactive to the
date of their occurrence in accordance with the other provisions of this Plan,
and this Article 18.3 shall be of no further force or effect.

attachment, garnishment, execution, sequestration or other legal or equitable
process, or transferability by operation of law in event of bankruptcy,
insolvency or otherwise, except security interests taken in a Participant's
Account(s) for loans made to Participants pursuant to Article 13 of the Plan and

                                CLAIMS PROCEDURE

     20.1 General Procedure. The Plan shall pay benefits to a Participant or the
Participant's Beneficiary in accordance with the Participant's election, as
provided in Article 12.1. If the Participant or Beneficiary believes that his
benefits have been incorrectly determined, he may make a written application for
benefits requesting a review of the determination previously made by the
Committee.

     All such applications for review shall be submitted to the Committee at the
offices of the Employer currently located at 555 River Oaks Parkway, San Jose,
CA 95134 in writing on the forms prescribed by the Committee and must be signed
by the Participant, or in the case of a death benefit, by the Beneficiary or
legal representative of the deceased Participant. Each application shall be
acted upon and approved or disapproved within ninety (90) days following its
receipt by the Committee. In the event any application for benefits is denied,
in whole or in part, the Committee shall notify the applicant in writing of such
denial and of his right to a review by the Employer. Said denial shall set forth
in a manner calculated to be understood by the applicant specific reasons for
such denial, specific references to pertinent Plan provisions on which the
denial is based, a description of any additional material or information
necessary for the applicant to perfect his application, an explanation of why
such material or information is necessary and an explanation of the Plan's
review procedure.

     20.2 Appeal. Any person, or his duly authorized representative, whose
application for benefits is denied in whole or in part, or who believes that his
benefits have been incorrectly determined, may appeal from such denial to the
Employer for a review of the decision by submitting to the Employer within sixty
(60) days after receiving written notice from the Committee of the denial of his
claims a written statement:

          (a) Requesting a review of his application for benefits by the
Employer;

          (b) Setting forth all of the grounds upon which his request for review
is based and any facts in support thereof; and

          (c) Setting forth any issues or comments which the applicant deems
pertinent to this application.

     20.3 Appointment of Review Committee. Upon receipt of an application for
review submitted in accordance with Article 20.2, the Employer shall appoint an
independent review committee composed of not fewer than 3 individuals who did
not participate in the Committee's original determination. The review committee
shall act upon such application within 60 days after the receipt by the Employer
of the applicant's request for review.

     20.4 Procedure of Review Committee to Review Appeals.

                                       64
   50
          (a) The review committee shall make a full and fair review of each
such application and any written materials submitted by the applicant in
connection therewith and may require the Committee or the applicant to submit
such additional facts, documents or other evidence as the review committee, in
its sole discretion, deems necessary or advisable in making such a review. On
the basis of its review, the review committee shall make a determination of the
applicant's eligibility for benefits under the Plan. The decision of the review
committee on any application for benefits shall be final and conclusive upon all
persons if supported by substantial evidence in the record.

          (b) In the event the review committee denies an application in whole
or in part, the review committee shall give written notice of its decision to
the applicant setting forth in a manner calculated to be understood by the
applicant the specific reasons for such denial and the specific references to
the pertinent Plan provisions on which the review committee decision was based.

                                   ARTICLE 21
                              TOP HEAVY PROVISIONS

     21.1 Top Heavy Determination. The Plan will be considered a Top Heavy Plan
for the Plan Year if as of the last day of the preceding Plan Year, (or in the
case of the first Plan Year of the Plan, the last day of such Plan Year) (1) the
value of the sum of the Accounts of Key Employees (as defined in Article 21.5)
exceeds 60% of the value of the sum of the Accounts of all Participants and
certain former participants in the Plan (the "60% Test") or (2) the Plan is part
of a Required Aggregation Group (within the meaning of section 416(g) of the
Internal Revenue Code) and the Required Aggregation Group is a Top Heavy Group.

     In determining the value of Accounts of the Participants for purposes of
the 60% Test, any distributions made with respect to an Employee under the Plan
during the five year period ending on the determination date or any
distributions under a terminated plan which if it had not been terminated would
have been part of a Required Aggregation Group, shall be taken into account. In
determining the value of Accounts of Participants for purposes of the 60% Test,
any contributions to the Plan made pursuant to Article 4 initiated by an
Employee and not made from a plan maintained by the Employer shall not, except
to the extent provided by Treasury Regulations promulgated under section
416(g)(4)(A) of the Code, be taken into account. (Amended effective 1/1/89,
Third Amendment) A Participant's Accounts for purposes of applying the 60% Test
shall be measured as of the most recent Valuation Date occurring within a
12-month period ending on the determination date, and an adjustment in the
amount of any contributions actually made after the Valuation Date but on or
before the determination date. In the first Plan Year, such adjustment shall
also include the amount of any contributions made after the determination date
that are allocated as of a date in the first Plan Year. An individual's Accounts
shall not be taken into consideration for the purposes of 


                                       65
   51
applying the 60% Test if either (i) that individual was a Non-Key Employee with
respect to the Plan for any Plan Year, but such individual was a Key Employee
with respect to the Plan prior to a Plan Year in which the individual was a
Non-Key Employee, or (ii) that individual has not performed any services for the
Employer at any time during the 5-year period ending on the determination date.
Notwithstanding the results of the 60% Test, the Plan shall not be considered a
Top Heavy Plan for any Plan Year in which the Plan is a part of a Required
Aggregation Group or permissive aggregation group (within the meaning of section
416(g) of the Internal Revenue Code) which is not a Top Heavy Group.

     21.2 Required Aggregation Group. "Required Aggregation Group" shall mean
each plan of the Employer which has a Key Employee as a Participant and any
other Employer plan (including a terminated plan of the Employer to the extent
required by validly issued Treasury regulations) which enables a plan of the
Employer in which a Key Employee is a participant to meet the requirements of
section 401(a)(4) or 410 of the Code. In applying the 60% Test to two or more
plans, the 60% Test is applied to each plan and then the plans are aggregated by
adding together the results as of each plan's determination date which falls
within the same calendar year.

     21.3 Top Heavy Group. "Top Heavy Group" shall mean any aggregation group
whether or not a Required Aggregation Group, which meets the 60% Test. In
applying the 60% Test to two or more plans, the 60% Test is applied to each plan
and then the plans are aggregated by adding together the results as of each
plan's determination date which falls within the same calendar year.

     21.4 Minimum Contribution for Top Heavy Plan. For any Plan Year in which
the Plan is a Top Heavy Plan, an amount shall be credited to the 401(k) Account
of each Employee who is not a Key Employee and who is eligible to share in this
special minimum contribution for a Top Heavy Plan pursuant to paragraph (c)
below which is equal to:

          (a) the lesser of:

               (i) the amount of the 401 (k) Contributions expressed as a
percentage of Compensation which is credited to the Accounts with respect to
such Plan Year of the Key Employee having the highest such percentage, or

               (ii) 3% of Compensation,

          (b) reduced by the amount of the 401 (k) Contributions, Company
Contributions. Profit Sharing Contributions, and Matching Contributions, if any,
otherwise credited to the Accounts of each Employee who is not a Key Employee
for such Plan Year.

          (c) All Participants who are not Key Employees and who have not
separated from service prior to the last day of the Plan Year are eligible to
share in this special minimum contribution for a Top Heavy Plan described in
this Article 21.4.

     21.5 Key Employees.

                                       66
   52
          (a) The term "Key Employee" shall mean an Employee who, at any time

Code section 415(b)(1)(A) (or such greater amount as may be permitted pursuant
to regulations issued under Code section 415(d)(1)) for any such Plan Year;

               (2) one of ten Employees having annual compensation from the
Company of more than the maximum dollar amount set forth in Code section
415(b)(1)(A) and owning (or considered as owning within the meaning of Code
section 318), the largest interests in the Company;

               (3) a five percent (5%) owner of the Company; or

               (4) a one percent (1%) owner of the Company, having an annual
compensation from the Company of more than $150,000.

          (b) For purposes of (a)(1) above, no more than fifty (50) Employees
(or, if fewer, the greater of three (3) Employees or ten percent (10%) of the
Employees) shall be treated as officers. For purposes of paragraph a)(2) above,
if two Employees have the same interest in the Company, the Employee having the
greater Compensation from the Company shall be treated as having a larger
interest.

          (c) For purposes of this definition:

               (1) "5% owner" shall mean, in the case of a corporation, any
person who owns (or who is considered as owning within the meaning of Code
section 318) more than 5% of the outstanding stock of the corporation or stock
possessing more than 5% of the total combined voting power of all stock of the
corporation and in case the Company is not a corporation, any person who owns
more than 5% of the capital or profits interest in the Company; and

               (2) a "1% owner" is any person who would be described in
subparagraph (c)(1), above, if "1%" were substituted for "5%" each place it
appears therein.

          (d) For purposes of paragraphs (a)(2) and (c) above, the rules of Code
section 318 shall be modified as set forth in Code section 416(i)(1)(B)(iii).

          (e) A Key Employee shall also include the Beneficiary of a Key
Employee.

          (f) A Key Employee shall include an individual who is either currently
or was formerly employed by the Company who meets the definition set forth in
paragraph (a) above.

     21.6 Non-Key Employee. "Non-Key Employee" shall mean any Employee who is
not a Key Employee.

     21.7 Top Heavy Vesting.

          (a) In any Plan Year in which the Plan is a Top Heavy Plan, the
Accounts of a Participant shall vest in accordance with the following Top Heavy
Vesting Schedule, except to the extent the regular vesting schedule set forth in
Article 10 provides for a rate of vesting which is as rapid as or more rapid
than the Top Heavy Vesting Schedule selected in this Article 21.7.

                  6                         100%


          (b) For the purposes of determining a Participant's Years of Service
applicable to the Top Heavy Vesting Schedule set forth in Article 21.7(a), all
of the Participant's service with the Employer shall be taken into account.

          (c) If the Plan becomes a Top Heavy Plan and subsequently ceases to be
such, the Top Heavy Vesting Schedule set forth in Article 21.7(a) shall continue
to apply in determining the vested percentage of the Matching Account for any
Participant who had at least three Years of Service as of the last Plan Year in
which the Plan was a Top Heavy Plan.

                                   ARTICLE 22
                                  MISCELLANEOUS

     22.1 No Employment Relationship Established by Plan. The adoption and
maintenance of the Plan and Trust shall not be deemed to be a contract between
the Employer and any Employee. Nothing herein contained shall be deemed to give
any Employee the right to be retained in the employ of the Employer or to
interfere with the right of the Employer to discharge any Employee in its employ
at any time, nor shall it be deemed to give the Employer the right to require
any Employee to remain in its employ, nor shall it interfere with the Employee's
right to terminate his employment at any time.

     22.2 Trustee to Trustee Transfer. Plan Merger or Consolidation.

          (a) Effective October 1, 1994, the Committee may direct the Trustee to
effect a trustee-to-trustee transfer of the assets and liabilities attributable
to a Participant's Account, including any promissory note evidencing an
outstanding loan made to the participant pursuant to the terms of the Plan, to
another plan provided such transfer is requested by the Participant. No such
transfer shall be made unless immediately after such transfer, the Participant's
benefits, if such other plan were then to terminate, are at least equal to or
greater than the benefits which the participant would have been entitled to had
this Plan been terminated immediately before such transfer. The Committee may
also request appropriate indemnification from the employer or employers
maintaining the transferee plan before making such a transfer.

          (b) In no event shall this Plan be merged or consolidated with any
other plan, nor shall there be any transfer of assets or liabilities from this
Plan to any other plan, unless immediately after such merger, consolidation or
transfer, each Participant's benefits, if such other plan were then to
terminate, are at least equal to 


                                       68
   54
or greater than the benefits which the participant would have been entitled to
had this Plan been terminated immediately before such merger, consolidation, or
transfer.

          (c) If the Employer merges or consolidates with or into a corporation,
or if substantially all of the assets of the Employer shall be transferred to a
corporation, the Plan hereby created shall terminate on the effective date of
such merger, consolidation or transfer. However, if the surviving corporation
resulting from such merger or consolidation, or the corporation to which the
assets have been transferred, adopts this Plan, the Plan shall continue and said
corporation shall succeed to all rights, powers and duties of the Employer
hereunder. The employment of any Employee who is continued in the employ of such
successor corporation shall not be deemed to have been terminated for any
purpose hereunder.

     22.3 Section 415 Limits on Allocations.

          (a) Notwithstanding anything in this Plan to the contrary, in
accordance with the requirements of section 415 of the Code, no contribution to
the Plan shall knowingly be made and no amount allocated to the Participant's
401 (k) Account, Matching Account or Company Contribution Account and Profit
Sharing Account if such contribution or allocation would cause the Annual
Addition to the Participant's Accounts for a Plan Year to exceed the lesser of:
(1) 25% of the Participant's Compensation from the Employer for such Plan Year,
or (2) the Defined Contribution Dollar Limitation.

          (b) For purposes of this Article 22.3, the following definitions and
rules shall apply:

               (1) "Annual Addition" shall mean for any Plan Year the sum of:

                    (A) Employer contributions (including 401(k) Contributions)
allocated to a Participant's Accounts, (B) forfeitures allocated to a
Participant's Account, and (C) Employee contributions (not including Rollover
Contributions), and (D) amounts described in section 415(1)(1) and 419A(d)(2) of
the Code.

               (2) "Defined Contribution Dollar Limitation" shall mean $30,000
or, if greater, one-fourth of the defined benefit limitation set forth in
section 415(b)(i) of the Code in effect for such Plan Year.

               (3) If the Employer is contributing to another defined
contribution plan, as defined in section 414(i) of the Code, for Employees of
the Employer, some or all of whom may be Participants of this Plan, then any
such Participant's Annual Addition in such other plan shall be aggregated with
such Participant's Annual Addition derived from this Plan for purposes of the
limitation in this Article 22.3(a).

          (c) If a Participant in this Plan is also a participant in a defined
benefit plan, as defined in section 414(j) of the Code, to which contributions
are made by the Employer, then in addition to the limitation contained in
Article 22.3(a), for any Plan Year the sum of his defined benefit plan fraction
(as defined by section 415(e)(2) of the Code) for all such plans and his defined
contribution plan fraction (as defined by section 415(e)(3) of the Code) for all
such plans 


                                       69
   55
for such Plan Year shall not exceed 1.0.

          (d) In order to implement the limitations set forth in Articles
22.3(a) and 22.3(b), the aggregate of the Annual Additions to this Plan and the
Annual Addition to any other defined contribution plan shall be limited or
reduced until the applicable limitation is satisfied, by limiting or reducing
the aggregate amount as follows:

               (1) Refund of any voluntary contributions made by the Participant
to any other defined contribution plan which would be aggregated with the Annual
Additions to the Plan; 

               (2) To the extent permitted by regulations promulgated by the
Secretary of the Treasury, refund of the Participant's 401(k) Contributions and
earnings thereon.

               (3) Reduction in the Participant's 401(k) Contributions and
earnings thereon for the Plan Year in which the excess arises. Such reduction
shall be held in a separate suspense account, which shall be unadjusted for
income or loss, and shall serve to reduce 401(k) Contributions to the
Participant's 401(k) Account in the next Plan Year and in succeeding Plan Years
until the suspense account is exhausted.

               (4) Reduction in the Participant's allocation of Company
Contributions and Profit Sharing Contributions, if any, for the Plan Year in
which the excess arises. Such reduction shall be credited to a separate suspense
account, which shall be unadjusted for income or loss, and shall serve to reduce
Company Contributions and Profit Sharing Contributions to the Plan in the next
Plan Year and in succeeding Plan Years, as necessary, until the suspense account
is exhausted. The Employer shall make no further Company Contributions and
Profit Sharing Contributions under the Plan until such suspense account is
exhausted. Upon the termination of the Plan, the balance credited to such
suspense account shall be repaid to the Employer.

               (5) Reduction in the Participant's allocation of Matching
Contributions for the Plan Year in which the excess arises. Such reduction shall
be held in a separate suspense account, which shall be unadjusted for income or
loss, and shall serve to reduce Matching Contributions to the Plan in the next
Plan Year and succeeding Plan Years until the suspense account is exhausted. The
Employer shall make no further Matching Contributions under the Plan until such
suspense account is exhausted. Upon the termination of the Plan, the balance
credited to such suspense account shall be repaid to the Employer.

     22.4 Qualified Domestic Relations Orders.

          (a) In accordance with section 414(p) of the Code, section 206(d)(3)
of ERISA, and any regulations promulgated thereunder, the Committee shall
establish reasonable written procedures to determine the qualified status of
domestic relations orders received with respect to Participants and to
administer distributions to alternate payees under such qualified domestic
relations orders.

          (b) Notwithstanding any provision in the Plan to the contrary, and in
accordance with reasonable procedures applied in a uniform and nondiscriminatory
manner, the Committee shall direct the Trustee 


                                       70
   56
to make a payment as soon as administratively feasible to an alternate payee
pursuant to the terms of a qualified domestic relations order received with
respect to a Participant, regardless of whether such Participant has terminated
employment with the Company; provided, however, that if the amount of such
payment exceeds $3,500 (and at the time of any prior distribution had not
exceeded $3.500), the payment shall not be made without the written consent of
the alternate payee.

          (c) Any payment to an alternate payee, or to his legal representative
or beneficiary, pursuant to the terms of a qualified domestic relations order
shall be in full satisfaction of all claims under such order against the
Employer, the Committee, or the Trustee, as the case may be, any of whom may
require such alternate payee, or his legal representative or beneficiary, to
execute a receipt therefor in such form as shall be determined by the Employer,
the Committee, or the Trustee, as the case may be.

     22.5 Notices. All notices, statements and other communications from the
Trustee, the Employer or the Committee to an Employee, Participant, legal
representative or designated Beneficiary required or permitted hereunder shall
be deemed to have been duly given, furnished, delivered or transmitted, as the
case may be, when delivered to (or when mailed by first-class mail, postage
prepaid and addressed to) the Employee, Participant or Beneficiary at his
address last appearing on the books of the Employer.

     22.6 Severability. If any provision of this Plan shall be held by a court
of competent Jurisdiction to be invalid or unenforceable, the remaining
provisions of the Plan shall continue to be fully effective.

     IN WITNESS WHEREOF, Cadence Design Systems, Inc. adopts this Plan effective
as of the date set forth above.
