 ARTICLE I. 
 INTRODUCTION 
 Exponent, Inc. maintains the Exponent, Inc. 401(k)
Savings Plan, consisting of the following provisions, for the exclusive benefit of Participants and their Beneficiaries (and for defraying reasonable administrative expenses of the Plan). The Plan was originally established effective as of
March 1, 1988 as The Failure Group, Inc. 401(k) Savings Plan, and the Plan has been subsequently renamed, and amended and restated on several occasions. The Company further amends and restates the Plan, in its entirety, effective as of
January 1, 2010 (except as otherwise stated herein). 
 Effective as of July 1, 1999, the Performance Technologies,
Incorporated Savings Plan was merged with and into the Plan. Effective as of June 30, 1994, the Exponent, Inc. Employee Pension Plan (formerly named The Failure Group, Inc. Employee Pension Plan) was merged with and into the Plan. Previously,
effective as of December 30, 1994, The Failure Analysis Associates Employee Pension Plan was merged with and into the Exponent, Inc. Employee Pension Plan. In all cases, the protected benefits have been preserved, as set forth in the Appendices
attached hereto, for purposes of complying with Internal Revenue Code (the “Code”) Section 411(d)(6). 
 The Plan
is intended to be a tax-qualified profit sharing plan and related tax-exempt trust under Code Sections 401(a) and 501(a), and is intended to include a tax-qualified cash or deferred arrangement under Code Section 401(k) and Roth salary
deferral contributions under Code Section 402A, and is intended to provide for the possibility that a matching contribution arrangement under Code Section 401(m) may be implemented at a later date. The Plan is also intended to provide
participant-directed investment accounts in compliance with ERISA Section 404(c).

 Wherever used in this Plan, the following terms shall
have the meanings indicated below, unless a different meaning is plainly required by the context or if such term is defined differently for particular groups of Participants in one or more of the Appendices. The singular shall include the plural,

following: Salary Deferral Contributions Account, Roth Salary Deferral Contributions Account, Employer Mandatory Contributions Account, Employer Matching Contributions Account, Qualified Matching Contributions Account, Qualified Nonelective

the above-mentioned accounts, as applicable.

 2 








 
described below), or on account of an authorized leave of absence (as described in Section 8.1 or 8.2), shall receive credit for the Hours of Service which would otherwise have been credited
to such individual but for such absence, or in any case in which such hours cannot be determined, eight (8) Hours of Service for each day of such absence. 
 (b) For purposes of paragraph (a) above, “maternity or paternity leave” means a period during which an Employee is absent because of (i) the pregnancy of the Employee, (ii) the

Employee’s base salary or wages, including Excellence Awards, overtime, vacation pay, holiday pay, severance paid in lieu of notice, and accrued vacation pay paid as a result of termination of employment. Compensation shall also include any
amount which is contributed by the Employer pursuant to a salary deferral agreement and which is not includable in the gross income of the Employee under Code Section 125, 402(e)(3), 402(h) or 403(b). Compensation includes amounts that are
excluded from the Employee’s taxable income by reason of Code Section 132(f)(4) relating to qualified transit benefits. Compensation shall exclude bonuses and reimbursements for moving and relocation expenses and all other forms of
remuneration not specifically named herein. 
 (a) Compensation shall include only that compensation which is actually paid or
made available to the Employee during the Plan Year. 
 (b) The annual Compensation of each Employee that is taken into account
under the Plan for any Plan Year shall not exceed Two Hundred Thousand Dollars ($200,000), as adjusted for cost-of-living increases in accordance with Code Section 401(a)(17)(B). 

(c) The determination of the amount of Compensation shall be made by the Participating Employer (or its designee) by which the Employee
is employed, in accordance with the records of the Participating Employer, and shall be conclusive. Effective January 1, 2009, Compensation shall include differential wage payments within the meaning of Code Section 414(u)(12)(D) that are
paid to an Employee by an Employer.

 3.2 Reemployment. If either a Participant, or an Eligible Employee who has satisfied the age requirement of Section 3.1 terminates employment with a Participating Employer and is

Participant in the Plan. 
 3.3 Change in Employment Status. If a Participant ceases to be an Eligible Employee,
then such Employee shall be reinstated as a Participant upon again becoming an Eligible Employee. If, however, an Employee who is not, and has never been, an Eligible Employee becomes an Eligible Employee, then such Employee shall become a

3.4 Enrollment of Participant. Each Eligible Employee shall comply with such enrollment procedures as the Administrator may
prescribe from time to time and shall make available to the Administrator and the Trustee any information they may request. By virtue of his or her participation in the Plan, an Eligible Employee agrees, on his or her behalf and on behalf of all

 ARTICLE IV. 
 CONTRIBUTIONS 
 4.1 Salary Deferral Contributions.

Section 3.1 may elect, in accordance with the procedures established from time to time by the Administrator, to have a portion of his or her Compensation contributed to his or her Salary Deferral Contributions Account. The Participant’s

Section 401(k)(3), 401(k)(1l), 401(k)(12), 410(b), or 416, as applicable, by reason of the making of such Catch-up Contributions. 
 (c) For purposes of the Plan, and with respect to Salary Deferral Contributions made on behalf of any Participant, such Salary Deferral Contributions shall be allocated to the Participant’s Salary
Deferral Contributions Account as of a given date within the Plan Year and shall relate to Compensation that would have been received by the Participant in the Plan Year but for the Participant’s election to defer such Compensation.

the Participant would have received that amount in cash if the Eligible Employee had not made a cash or deferred election. 

(b) Except as otherwise provided herein, Roth Salary Deferral Contributions shall be treated as Salary Deferral Contributions for all
purposes under the Plan. 
 4.3 Employer Matching Contributions and Qualified Matching Contributions.

Retirement, Early Retirement, Disability or death of such Participant during the applicable Plan Year. 
 (b) The Employer may
further elect to make an additional Matching Contribution, to be allocated as of the last day of the Plan Year to Participants as an end of the year adjustment to take into account any changes in Compensation or Participant salary deferral elections
which may have occurred during the Plan Year. The amount of this additional Employer Matching Contribution shall be equal to the difference, if any, between (i) the Employer Matching Contributions allocated to the Participant pursuant to
paragraph (a), and (ii) an Employer Matching Contribution determined pursuant to any applicable formula which the Company may elect, but based on a Participant’s Compensation and Salary Deferral Contributions for the Plan Year. This
additional Employer Matching Contribution, if any, shall be allocated to the Employer Matching Contributions Account of all the Participants specified by the Company from time to time of all Participants actively employed by the Employer on the last
day of the Plan Year, or not actively employed by the Employer on the last day of the Plan Year due to such Participant’s attainment of Normal Retirement age, Disability or death during the applicable Plan Year. 

(c) Employer Matching Contributions which would otherwise be made on behalf of a Participant may be reduced to the extent necessary to
comply with the limitations of Sections 4.5, 5.4, 5.5 and 5.7, and the Employer shall have no obligation to contribute such amounts to the Trust. 

  
 17 









 (d) The Administrator may elect to treat all or a portion of Employer Matching Contributions
for a Plan Year as Qualified Matching Contributions for purposes of the ADP Test. Such contributions, to the extent necessary, shall satisfy the requirements of Treasury Regulation Section 1.402(m)-2(a)(5).

of Lockwood and became Employees on September 30, 2000 shall be credited under the Plan with all hours of service and years of service such Participants earned from December 26, 1998 to September 29, 2000 while employed by Lockwood.

and after December 30, 2001, the Employer Mandatory Contributions for each Plan Year shall be allocated among the Employer Mandatory Contributions Accounts of all eligible Participants who are credited with one (1) Year of Service. For
purposes of determining whether an allocation of an Employer Mandatory Contribution shall be made for the Plan Year commencing January 1, 2002, Participants who were employed by Novigen immediately prior to the Company’s acquisition of
Novigen and became Employees on May 20, 2002 shall be credited under the Plan with all hours of service such Participants earned from January 1, 2002 to May 19, 2002 while employed by Novigen. For purposes of the foregoing, the term

satisfy the requirements of Treasury Regulations Section 1.401(k)-2(a)(6) and 1.401(m)-2(a)(6). 
 (e) For all purposes of
the Plan, Employer Mandatory Contributions and Qualified Nonelective Contributions shall be subject to the distribution limitations of Article VI. Amounts allocated to a Participant’s Qualified Nonelective Contributions Account shall not
be eligible for hardship distribution under Section 6.17.

requirements of applicable law.

Employee in accordance with Code Section 402(c) or 501(a); (iii) received from the Eligible Employee in accordance with Code Section 402(c) or 408(d)(3); or (iv) transferred in the form of a Direct Rollover from another

credited with all amounts attributable to Roth Salary Deferral Contributions pursuant to Section 4.2 and amounts rolled over to the Plan from another Roth elective deferral account under an applicable retirement plan described in Code
Section 402A(e)(1). 
 (c) Employer Mandatory Contributions. A Participant’s Employer Mandatory Contributions
Account shall be credited with all amounts attributable to Employer Mandatory Contributions pursuant to Section 4.4. 
 (d)
Employer Matching Contributions. A Participant’s Employer Matching Contributions Account shall be credited with all amounts attributable to Employer Matching Contributions pursuant to Section 4.3. 

(e) Qualified Matching Contributions. A Participant’s Qualified Matching Contributions Account shall be credited with all
amounts attributable to Qualified Matching Contributions pursuant to Section 4.3. 
 (f) Qualified Nonelective
Contributions. A Participant’s Qualified Nonelective Contributions Account shall be credited with all amounts attributable to Qualified Nonelective Contributions pursuant to Section 4.4. 

(g) Rollover Contributions. A Participant’s Rollover Contributions Account shall be credited with all amounts transferred to
the Plan pursuant to Section 4.7. 
 (h) PTI Plan Account. A Participant’s PTI Plan Account shall be maintained
on behalf of each Participant whose account balance was transferred from the Performance Technologies, Incorporated Savings Plan to this Plan pursuant to the merger of that plan with and into this Plan. 

(i) Pension Plan Account. A Participant’s Pension Plan Account shall be maintained on behalf of each Participant whose
account balance was transferred from The Failure Group, Inc. Employee Pension Plan to this Plan pursuant to the merger of that plan with and into this Plan. 

  
 21 









 (j) FaAA Plan Account. A Participant’s FaAA Plan Account shall be maintained on
behalf of each Participant whose account balance was transferred from The Failure Analysis Associates Employee Pension Plan to this Plan pursuant to the merger of that plan with and into this Plan. 

(k) Other Accounts. Such other Account(s) as the Administrator shall deem necessary or appropriate. 

5.2 Allocation of Contributions. As of each Valuation Date, the Administrator shall allocate to the Accounts of each
Participant the Contributions made on his or her behalf, and, if applicable, the Rollover Contributions, since the preceding Valuation Date. 
 5.3 Allocation of Earnings. 
 (a) As of each Valuation Date, the
Trustee shall determine the net fair market value of all assets of the Trust, and the Trustee shall then report such value to the Administrator. The Administrator shall adjust each Account: first, to reflect any allocations made to, or any
distributions or withdrawals made from, such Account since the immediately preceding Valuation Date, to the extent not previously credited or charged thereto, and second, to reflect the Earnings allocable to each Account in accordance with paragraph
(b) below. If an allocation of Contributions and/or Rollover Contributions is to be made to the Accounts as of the same Valuation Date, then the adjustments required under this Section shall be made prior to such allocation. 

(b) The Administrator shall maintain a separate record of all Earnings of the Trust attributable to each Participant’s Account. Each
Participant’s Account shall be credited or charged with the Earnings attributable to the investments in such Account over the relevant period as of each Valuation Date. 
 5.4 Section 415 Limitations. 
 (a) Limitation on Annual
Contributions. Notwithstanding any other provision of the Plan, except to the extent permitted under Code Section 414(v), the maximum Annual Addition (as defined in Subsection (b) of this Section 5.4) to a Participant’s
Account for any limitation year (which shall be the calendar year) shall in no event exceed the lesser of (a) 100% of his Section 415 Compensation for such year whether or not he is a Participant for the entire year, or (b) $40,000
(as adjusted pursuant to Code Section 415(d)). 
 (b) Definition of Annual Addition. For the purposes of this
Section 5.4, the term “Annual Addition” shall mean the sum for any calendar year of: 
 (i) all contributions
allocated to the Participant’s Account pursuant to a defined contribution plan maintained by the Employer; 

  
 22 









 (ii) all forfeitures allocated to the Participant’s Account pursuant to a defined
contribution plan maintained by the Employer; and 
 (iii) in the case of a Participant who, at any time during such year or
any preceding year, is or was a key employee (as such term is defined in Code Section 416(i)), any amount attributable to medical benefits allocated to an account established on his behalf under Code Section 419A(d)(1). 

(c) Maximum Annual Additions. For purposes of applying the limitations set forth in Subsection (a), all qualified defined
contribution plans (whether or not terminated) ever maintained by the Employer shall be treated as one defined contribution plan. 
 (d) Correction of Excess Annual Addition. If the limitation on Annual Additions is exceeded with respect to any Participant for a Plan Year, such excess Annual Addition shall be corrected in
accordance with the Employee Plans Compliance Resolutions System (EPCRS), as set forth in Revenue Procedure 2008-50 or any superseding guidance issued by the Internal Revenue Service or the Treasury Department. 

5.5 Discrimination Testing of Salary Deferral Contributions. 

(a) Definitions. 
 (i) “Actual Deferral Percentage” (“ADP”) shall mean, for a specified group of Participants (either Highly Compensated Employees or Non-Highly Compensated Employees) for a Plan Year,
the average of the ratios (calculated separately for each Participant in such group) of (1) the amount of Employer contributions actually paid over to the Trust on behalf of such Participant for the Plan Year to (2) the Participant’s
Section 415 Compensation for such Plan Year. Employer contributions on behalf of any Participant shall include: (1) any Elective Deferrals (other than Catch-up Contributions) made pursuant to the Participant’s deferral election
(including Excess Elective Deferrals of Highly Compensated Employees), but excluding (a) Excess Elective Deferrals of Non-Highly Compensated Employees that arise solely from Elective Deferrals made under the Plan or plans of this Employer and
(b) Elective Deferrals that are taken into account in the Actual Contribution Percentage test (provided the ADP test is satisfied both with and without exclusion of these Elective Deferrals); and (2) Qualified Nonelective Contributions and
Qualified Matching Contributions. For purposes of computing Actual Deferral Percentages, an Employee who would be a Participant but for the failure to make Elective Deferrals shall be treated as a Participant on whose behalf no Elective Deferrals
are made. 

  
 23 









 (ii) “Excess Contributions” shall mean, with respect to any Plan Year, the excess
of (1) the aggregate amount of Employer contributions actually taken into account in computing the ADP of Highly Compensated Employees for such Plan Year, over (2) the maximum amount of such contributions permitted by the ADP test
(determined by hypothetically reducing contributions made on behalf of Highly Compensated Employees in order of the ADPs, beginning with the highest of such percentages). 
 (b) ADP. The ADP for a Plan Year for Participants who are Highly Compensated Employees for each Plan Year and the prior year’s ADP for Participants who were Non-Highly Compensated Employees
for the prior Plan Year must satisfy one of the following tests: 
 (i) The ADP for a Plan Year for Participants who are Highly
Compensated Employees for the Plan Year shall not exceed the prior year’s ADP for Participants who were Non-Highly Compensated Employees for the prior Plan Year multiplied by 1.25; or 

(ii) The ADP for a Plan Year for Participants who are Highly Compensated Employees for the Plan Year shall not exceed the prior
year’s ADP for Participants who were Non-Highly Compensated Employees for the prior Plan Year multiplied by 2.0, provided that the ADP for Participants who are Highly Compensated Employees does not exceed the ADP for participants who were
Non-Highly Compensated Employees in the prior Plan Year by more than 2 percentage points. 
 (c) Special Rules.

 (i) A Participant is a Highly Compensated Employee for a particular Plan Year if he or she meets the definition of a Highly
Compensated Employee in effect for that Plan Year. Similarly, a Participant is a Non-Highly Compensated Employee for a particular Plan Year if he or she does not meet the definition of a Highly Compensated Employee in effect for that Plan Year.

 (ii) The ADP for any Participant who is a Highly Compensated Employee for the Plan Year and who is eligible to have Elective
Deferrals (and Qualified Nonelective Contributions or Qualified Matching Contributions, or both, if treated as Elective Deferrals for purposes of the ADP test) allocated to his or her Account under two or more arrangements described in Code
Section 401(k), that are maintained by the Employer, shall be determined as if such Elective Deferrals (and, if applicable, such Qualified Nonelective Contributions or Qualified Matching Contributions, or both) were made under a single
arrangement. If a Highly Compensated Employee participates in two or more arrangements described in Code Section 401(k) that are maintained by the Employer and that have different plan years, all Elective Deferrals made during the Plan Year
under all such arrangements shall be aggregated. Notwithstanding the foregoing, certain plans shall be treated as separate if mandatorily disaggregated under regulations under Code Section 401(k). 

  
 24 









 (iii) In the event that this Plan satisfies the requirements of Code Section 401(k),
401(a)(4), or 410(b) only if aggregated with one or more other plans, or if one or more other plans satisfy the requirements of such sections of the Code only if aggregated with this Plan, then this Section shall be applied by determining the ADP of
Employees as if all such plans were a single plan. If more than 10-percent of the Employer’s Non-Highly Compensated Employees are involved in a plan coverage change as defined in Treasury Regulations Section 1.401(k)-2(c)(4), then any
adjustments to the Non-Highly Compensated Employees’ ADP for the prior year will be made in accordance with such Treasury Regulations. Plans may be aggregated in order to satisfy Code Section 401(k) only if they have the same Plan Year and
use the same ADP testing method. 
 (iv) For purposes of determining the ADP test, Elective Deferrals, Qualified Nonelective
Contributions and Qualified Matching Contributions must be made before the end of the 12-month period immediately following the Plan Year to which the contributions relate. 

(d) Distribution of Excess Contributions. Notwithstanding any other provision of the Plan, Excess
Contributions, plus any income allocable thereto as provided in Section 5.5(e), shall be distributed no later than 12 months after the end of the Plan Year to Participants to whose Accounts such Excess Contributions were allocated for such Plan
Year, except to the extent such Excess Contributions are classified as Catch-up Contributions. Excess Contributions are allocated to the Highly Compensated Employees with the largest amounts of Employer contributions taken into account in
calculating the ADP test for the year in which the excess arose, beginning with the Highly Compensated Employee with the largest amount of such Employer contributions and continuing in descending order until all the Excess Contributions have been
allocated. To the extent a Highly Compensated Employee has not reached his or her Catch-up Contribution limit under the Plan, Excess Contributions allocated to such Highly Compensated Employee are Catch-up Contributions and will not be treated as
Excess Contributions. If such excess amounts (other than Catch-up Contributions) are distributed more than
2 1/2 months after the last day of the Plan Year in
which such excess amounts arose, a 10-percent excise tax will be imposed on the employer maintaining the Plan with respect to such amounts. Excess Contributions shall be treated as Annual Additions under the Plan even if distributed.

 (e) Determination of Income or Loss. Excess Contributions shall be adjusted for any income or loss allocable
thereto to the end of the Plan Year for which such Excess Contributions were made. The income or loss allocable to Excess Contributions allocated to each Participant is the income or loss allocable to the Participant’s Salary Deferral
Contributions Account (and, if applicable, the Roth Salary 

  
 25 









 
Deferral Contributions Account, Qualified Nonelective Contributions Account or the Qualified Matching Contributions Account or both) for the Plan Year multiplied by a fraction, the numerator of
which is such Participant’s Excess Contributions for the year and the denominator is the Participant’s Account balance attributable to Elective Deferrals (and Qualified Nonelective Contributions or Qualified Matching Contributions, or
both, if any of such contributions are included in the ADP test) without regard to any income or loss occurring during such Plan Year. 
 (f) Accounting for Excess Contributions. Excess Contributions allocated to a Participant shall be distributed from the Participant’s Salary Deferral Contributions Account, Roth Salary Deferral
Account, and Qualified Matching Contributions (if applicable) in proportion to the Participant’s Elective Deferrals and Qualified Matching Contributions (to the extent used in the ADP test) for the Plan Year. Excess Contributions shall be
distributed from the Participant’s Roth Salary Deferral Contributions Account only to the extent that the Excess Contributions exceed the amount of Excess Contributions in the Participant’s Salary Deferral Contributions Account and
Qualified Matching Contributions Account. Excess Contributions shall be distributed from the Participant’s Qualified Nonelective Contributions Account only to the extent that the Excess Contributions exceed the amount of Excess Contributions in
the Participant’s Salary Deferral Contributions Account, Qualified Matching Contributions Account, and Roth Salary Deferral Contributions Account. 
 5.6 Distribution of Excess Elective Deferrals. 
 (a)
Definitions. 
 (i) “Catch-up Contributions” are Elective Deferrals made to the Plan that are in excess of an
otherwise applicable Plan limit and that are made by Participants who are age 50 or over by the end of their taxable years. An otherwise applicable Plan limit is a limit in the Plan that applies to Elective Deferrals without regard to Catch-up
Contributions, such as the limits on Annual Additions, the dollar limitation on Elective Deferrals under Code Section 402(g) (not counting Catch-up Contributions) and the limit imposed by the actual deferral percentage (ADP) test under Code
Section 401(k)(3). Catch-up Contributions for a Participant for a taxable year may not exceed the dollar limit on Catch-up Contributions under Code Section 414(v)(2)(b)(i) for the taxable year. The dollar limit on Catch-up Contributions
under Code Section 414(v)(2)(B)(i) is $5,500 for taxable years beginning in 2010 and will be adjusted in later years by the Secretary of the Treasury for cost-of-living increases under Code Section 414(v)(2)(C). Any such adjustments will
be in multiples of $500. Catch-up Contributions are not subject to the limits on Annual Additions, are not counted in the ADP test and are not counted in determining the minimum allocation under Code Section 416 (but Catch-up Contributions made
in prior years are counted in determining whether the Plan is top-heavy). 

  
 26 









 (ii) “Elective Deferrals” shall mean any Employer contributions made to the Plan
at the election of the Participant in lieu of cash compensation. With respect to any taxable year, a Participant’s Elective Deferrals is the sum of all Employer contributions made on behalf of such Participant pursuant to an election to defer
under any qualified cash or deferred arrangement described in Code Section 401(k), any Roth contributions made on behalf of such Participant pursuant to an election to defer under Code Section 402A, any salary reduction simplified employee
pension described in Code Section 408(k)(6), any SIMPLE IRA plan described in Code Section 408(p) and any plan described under Code Section 501(c)(18), and any employer contributions made on behalf of a participant for the purchase of
an annuity contract under Code Section 403(b) pursuant to a salary reduction agreement. Elective Deferrals shall not include any deferrals properly distributed as excess Annual Additions. 

(iii) “Excess Elective Deferrals” shall mean those Elective Deferrals of a Participant that either (1) are made during
the Participant’s taxable year and exceed the dollar limitation under Code Section 402(g) (including, if applicable, the dollar limitation on Catch-up Contributions defined in Code Section 414(v)) for such year; or (2) are made
during a calendar year and exceed the dollar limitation under Code Section 402(g) (including, if applicable, the dollar limitation on Catch-up Contributions defined in Code Section 414(v)) for the Participant’s taxable year beginning
in such calendar year, counting only Elective Deferrals made under this Plan and any other plan, contract or arrangement maintained by the Employer. 
 (b) Limit on Elective Deferrals. No Participant shall be permitted to have Elective Deferrals made under this Plan, or any other plan, contract or arrangement maintained by the Employer, during any
calendar year, in excess of the dollar limitation contained in Code Section 402(g) in effect for the Participant’s taxable year beginning in such calendar year. In the case of a Participant aged 50 or over by the end of the taxable year,
the dollar limitation described in the preceding sentence includes the amount of Elective Deferrals that can be Catch-up Contributions. The dollar limitation contained in Code Section 402(g) is $16,500 for taxable years beginning in 2010 and
will be adjusted in later years by the Secretary of the Treasury for cost-of-living increases under Code Section 402(g)(4). Any such adjustments will be in multiples of $500. 

(c) Notification by Participant of Excess Elective Deferrals. A Participant may assign to this Plan any Excess Elective Deferrals
made during a taxable year of the Participant by notifying the Administrator on or before March 1st of the year following the close of the Participant’s taxable year in which the Excess Elective Deferrals were made. A Participant is deemed
to notify the Administrator of any Excess Elective Deferrals that arise by taking into account only those Elective Deferrals made to this Plan and any Other Plan of the Employer. 

  
 27 









 (d) Reimbursement of Excess Elective Deferrals and Forfeiture of Related Matching
Contributions. Notwithstanding any other provision of the Plan, Excess Elective Deferrals, plus any income and minus any loss allocable thereto to the end of the Plan Year for which such Excess Elective Deferrals were made, shall be distributed
no later than April 15th to any Participant to whose account Excess Elective Deferrals were assigned for the preceding year and who claims Excess Elective Deferrals for such taxable year or calendar year. Employer Matching Contributions made on
account of such Excess Elective Deferrals shall be forfeited as soon as administratively feasible thereafter and applied to reduce future Employer Contributions. 
 (e) Determination of Income or Loss. Excess Elective Deferrals shall be adjusted for any income or loss to the end of the Plan Year for which such Excess Elective Deferrals were made. The income or
loss allocable to Excess Elective Deferrals is the income or loss allocable to the Participant’s Salary Deferral Contributions Account or Roth Salary Deferral Contributions Account (as appropriate) for the taxable year multiplied by a fraction,
the numerator of which is such Participant’s Excess Elective Deferrals for the year and the denominator is the Participant’s account balance attributable to Elective Deferrals without regard to any income or loss occurring during such
taxable year. 
 5.7 Discrimination Testing of Employer Matching Contributions. 

(a) Definitions. 
 (i) “Actual Contribution Percentage” (“ACP”) shall mean, for a specified group of participants (either Highly Compensated Employees or Non-Highly Compensated Employees) for a Plan
Year, the average of the Contribution Percentages of the Eligible Participants in the group. 
 (ii) “Contribution
Percentage” shall mean the ratio (expressed as a percentage) of the Participant’s Contribution Percentage Amounts to the Participant’s Section 415 Compensation for the Plan Year. 

(iii) “Contribution Percentage Amounts” shall mean the sum of the Salary Deferral Contributions, Matching Contributions, and
Qualified Matching Contributions (to the extent not taken into account for purposes of the ADP test) made under the Plan on behalf of the participant for the Plan Year. Such Contribution Percentage Amounts shall not include Matching Contributions
that are forfeited either to correct Excess Aggregate Contributions or because the contributions to which they relate are Excess Deferrals, Excess Contributions, or Excess Aggregate Contributions. The Employer may include Qualified Nonelective
Contributions in the Contribution Percentage Amounts. The Employer also may elect to use Elective Deferrals in the Contribution Percentage Amounts so long as the ADP test is met before the Elective Deferrals are used in the ACP test and continues to
be met following the exclusion of those Elective Deferrals that are used to meet the ACP test. 

  
 28 









 (iv) “Eligible Participant” shall mean any Employee who is eligible to make an
Elective Deferral (if the Employer takes such contributions into account in the calculation of the Contribution Percentage) , or to receive an Employer Matching Contribution (including forfeitures) or a Qualified Matching Contribution. 

(v) “Matching Contribution” shall mean an Employer contribution made to this or any other defined contribution plan on behalf
of a Participant on account of a participant’s Elective Deferral, under a plan maintained by the Employer. 
 (b) Prior
Year Testing. The Actual Contribution Percentage (“ACP”) for a Plan Year for Participants who are Highly Compensated Employees for each Plan Year and the prior year’s ACP for Participants who were Non-Highly Compensated Employees
for the prior Plan Year must satisfy one of the following tests: 
 (i) The ACP for a Plan Year for Participants who are Highly
Compensated Employees for the Plan Year shall not exceed the prior year’s ACP for participants who were Non-Highly Compensated Employees for the prior Plan Year multiplied by 1.25; or 

(ii) The ACP for a Plan Year for Participants who are Highly Compensated Employees for the Plan Year shall not exceed the prior
year’s ACP for Participants who were Non-Highly Compensated Employees for the prior Plan Year multiplied by 2, provided that the ACP for Participants who are Highly Compensated Employees does not exceed the ACP for Participants who were
Non-Highly Compensated Employees in the prior Plan Year by more than 2 percentage points. 
 (c) Special Rules.

 (i) A Participant is a Highly Compensated Employee for a particular Plan Year if he or she meets the definition of a Highly
Compensated Employee in effect for that Plan Year. Similarly, a Participant is a Non-Highly Compensated Employee for a particular Plan Year if he or she does not meet the definition of a Highly Compensated Employee in effect for that Plan Year.

 (ii) For purposes of this Section, the Contribution Percentage for any Participant who is a Highly Compensated Employee and
who is eligible to have Contribution Percentage Amounts allocated to his or her account under two or more plans described in Code Section 401(a), or arrangements described in Code Section 401(k) that are maintained by the Employer, shall
be determined as if the total of such Contribution Percentage Amounts was made under each plan and arrangement. If a Highly Compensated Employee participates in two or more such plans or arrangements that have different plan years, all Contribution
Percentage Amounts made during the Plan Year under all such plans and arrangements shall be aggregated. Notwithstanding the foregoing, certain plans shall be treated as separate if mandatorily disaggregated under regulations under Code
Section 401(m). 

  
 29 









 (iii) In the event that this Plan satisfies the requirements of Code Sections 401(m),
401(a)(4) or 410(b) only if aggregated with one or more other plans, or if one or more other plans satisfy the requirements of such sections of the Code only if aggregated with this Plan, then this Section shall be applied by determining the ACP of
Employees as if all such plans were a single plan. If more than 10-percent of the Employer’s Non-Highly Compensated Employees are involved in a plan coverage change as defined in Treasury Regulations Section 1.401(m) - 2(c)(4), then any
adjustments to the Non-Highly Compensated Employees’ ADP for the prior year will be made in accordance with such Treasury Regulations. Plans may be aggregated in order to satisfy Code Section 401(m) only if they have the same Plan Year and
use the same ACP testing method. 
 (iv) For purposes of the ACP test, Matching Contributions and Qualified Nonelective
Contributions will be considered made for a Plan Year if made no later than the end of the 12 - month period beginning on the day after the close of the Plan Year. Employee Contributions are considered to have been made in the Plan Year in which
contributed to the Trust Fund. 
 5.8 Corrective Procedure for Discriminatory Matching Contributions. 

(a) Definition - Excess Aggregate Contributions. “Excess Aggregate Contributions” shall mean, with respect to any Plan
Year, the excess of: (a) the aggregate Contribution Percentage Amounts taken into account in computing the numerator of the Contribution Percentage actually made on behalf of Highly Compensated Employees for such Plan Year, over (b) the
maximum Contribution Percentage Amounts permitted by the ACP test (determined by hypothetically reducing contributions made on behalf of Highly Compensated Employees in order of their Contribution Percentages beginning with the highest of such
percentages). Such determination shall be made after first determining Excess Elective Deferrals and then determining Excess Contributions. 
 (b) Distribution of Excess Aggregate Contributions. Notwithstanding any other provision of the Plan, Excess Aggregate Contributions, plus any income and minus any loss allocable thereto to the end
of the Plan Year for which such Excess Aggregate Contributions were made, shall be forfeited, if forfeitable, or if not forfeitable, distributed no later than 12 months after a Plan Year to Participants to whose Accounts such Excess Aggregate
Contributions were allocated for such Plan Year. Excess Aggregate Contributions are allocated to the Highly Compensated Employees with the largest Contribution Percentage Amounts taken into account in calculating the ACP test for the year in which
the excess arose, beginning with the Highly Compensated Employee with the largest amount of such Contribution Percentage Amounts and continuing in descending order until all the Excess Aggregate Contributions have been


  
 30 









 
allocated. If such Excess Aggregate Contributions are distributed more than 2-1/2 months after the last day of the Plan Year in which such excess amounts arose, a 10-percent excise tax will be
imposed on the Employer with respect to those amounts. Excess Aggregate Contributions shall be treated as annual additions under the Plan even if distributed. 
 (c) Determination of Income or Loss. Excess Aggregate Contributions shall be adjusted for any income or loss to the end of the Plan Year for which such Excess Aggregate Contributions were made. The
income or loss allocable to Excess Aggregate Contributions allocated to each Participant is the income or loss allocable to the Participant’s Employer Matching Contributions Account, Qualified Matching Contributions Account (if any, and if all
amounts therein are not used in the ADP test) and, if applicable, Qualified Nonelective Contributions Account and Elective Deferral Account for the Plan Year multiplied by a fraction, the numerator of which is such Participant’s Excess
Aggregate Contributions for the year and the denominator is the Participant’s Account balance(s) attributable to Contribution Percentage Amounts without regard to any income or loss occurring during such Plan Year. 

(d) Forfeitures of Excess Aggregate Contributions. Forfeitures of Excess Aggregate Contributions shall be applied to reduce
Employer contributions. 
 (e) Accounting for Excess Aggregate Contributions. Excess Aggregate Contributions allocated to
a Participant shall be forfeited, if forfeitable or distributed on a pro-rata basis from the Participant’s Employer Matching Contributions Account, and Qualified Matching Contribution account (and, if applicable, one or more of the
Participant’s Qualified Nonelective Contributions Account, Salary Deferral Contributions Account, and Roth Salary Deferral Contributions Account). 

  
 31 









 ARTICLE VI. 
 VESTING AND DISTRIBUTION OF ACCOUNTS 
 6.1 Vested
Interest. 
 (a) A Participant’s interest in his or her Salary Deferral Contributions Account, Roth Salary Deferral
Contributions Account, Qualified Matching Contributions Account, Qualified Nonelective Contributions Account, Rollover Contributions Account, Pension Plan Account and FaAA Plan Account shall be at all times fully vested and nonforfeitable.

 (b) If a Participant, with a PTI Plan Account, was employed by the Company on December 31, 1998, then such
Participant’s PTI Plan Account shall be at all times fully vested and nonforfeitable. If, however, a Participant with a PTI Plan Account terminated employment with the Company prior to December 31, 1998, then such Participant’s vested
interest in his or her PTI Plan Account shall be determined according to the vesting Schedule in Appendix C. 
 (c) If
a Participant was employed by the Company, or any other Participating Employer who is designated by the Board to participate in making Employer Mandatory Contributions, on January 1, 1999, then such Participant’s interest in his or her
Employer Mandatory Contribution Account, if any, shall be at all times fully vested and nonforfeitable. 
 (d) A
Participant’s interest in his or her Employer Matching Contributions Account and, if the Participant’s Employment Commencement Date was after January 1, 1999, then his or her Employer Mandatory Contributions Account shall be fully
vested and nonforfeitable at the Participant’s Normal Retirement, death, Disability, or upon termination of the Plan. A Participant’s interest in his or her Employer Matching Contributions Account and Employer Mandatory Contributions
Account (to the extent not fully vested in paragraph (c) above) which is not fully vested shall be subject to the following vesting schedule: 
  

					
	 Years of Service
	  	Vested Percentage	 
	 Less than 1 year
	  	 	0	% 
	 1 year but less than 2 years
	  	 	20	% 
	 2 years but less than 3 years
	  	 	40	% 
	 3 years but less than 4 years
	  	 	60	% 
	 4 years but less than 5 years
	  	 	80	% 
	 5 years or more
	  	 	100	% 


  
 32 









 (e) In the case of an Employee who does not have a nonforfeitable right to a benefit under
the Plan, Years of Service before his Break in Service shall not be taken into account for purpose of the vesting Schedule only if the number of his consecutive one (1)-year Breaks in Service equals or exceeds the greater of five or the aggregate
number of his Years of Service before his Break in Service; and such aggregate number of his Years of Service before his Break in Service shall not include any Years of Service not required to be taken into account under this paragraph by reason of
any prior Break in Service. 
 (f) If the Plan is amended in any way that directly or indirectly affects the computation of the
Participant’s nonforfeitable percentage, or if the Plan is deemed amended by an automatic change to a Top-Heavy vesting schedule, then each Participant who is credited with three (3) Years of Service and whose Account would have vested
more rapidly prior to the amendment, may irrevocably elect during the election period to have the nonforfeitable percentage of his or her Account calculated without regard to such amendment. For purposes of this Section, the election period shall
begin the date the amendment is adopted, and shall end on the date sixty (60) days after the latest of (i) the date the amendment is adopted, (ii) the date the amendment becomes effective, or (iii) the date the Participant is
issued written notice of the amendment by the Participating Employer or the Administrator. For each Participant who has at least three (3) Years of Service and is not 100% vested in his Employer Matching Contributions Account and Employer
Mandatory Contributions Account, if any, on January 1, 2002, Years of Service for vesting purposes shall be calculated using either (i) the Company’s fiscal year, that is, the twelve (12) consecutive-month period beginning each
year on the Saturday which falls closest to the last day of December, and ending each year on the Friday which falls closest to the last day of December or (ii) the Company’s fiscal year through December 28, 2001 and commencing
January 1, 2002, the calendar year thereafter, whichever results in a larger vested percentage in the Participant’s Account. 
 (g) For purposes of determining a Participant’s vested percentage in his Employer Matching Contributions and Employer Mandatory Contributions, Participants who were employed by Novigen immediately
prior to the Company’s acquisition of Novigen and became Employees on May 20, 2002 shall be credited under the Plan with all hours of service and years of service such Participants earned while employed by Novigen. For purposes of the
foregoing, the terms “hours of service” and “years of service” shall be as defined in Sections 2.25 and 2.46, respectively, except that Novigen shall be considered the Employer. 

6.2 Forfeitures. 
 (a) If a Participant is required to take a distribution pursuant to Section 6.8 (the “cash-out rule”), then following the Participant’s Severance Date, the Participant shall receive a
distribution of the value of the entire vested portion of his or her Account balance in accordance with Sections 6.8 through 6.11. The nonvested 

  
 33 









 
portion of the Participant’s Account balance shall be treated as a forfeiture as of the earlier of (i) the date on which the distribution occurs, or (ii) the last day of the Plan
Year in which the Participant incurs five (5) consecutive one (1)-year Breaks in Service. For purposes of this Section, if the value of a Participant’s vested Account balance is zero (0), then the Participant shall be deemed to have
received a distribution of such vested Account balance as of his or her Severance Date. 
 (b) If a Participant has the option
to elect and does elect to receive the value of his or her vested Account balance following his or her Severance Date in accordance with the requirements of Section 6.8, then the nonvested portion of the Participant’s Account balance shall
be treated as a forfeiture as of the earlier of (i) the date on which the distribution occurs, or (ii) the last day of the Plan Year in which the Participant incurs five (5) consecutive one (1)-year Breaks in Service. 

(c) If a Participant has the option to elect and does not elect to receive the value of his or her vested Account balance following his
or her Severance Date in accordance with the requirements of Section 6.8, then the nonvested portion of the Participant’s Account balance shall be treated as a forfeiture as of the last day of the Plan Year in which the Participant incurs
five (5) consecutive one (1)-year Breaks in Service. 
 (d) If a Participant is not fully vested in his or her Account, and
that Participant receives a distribution in accordance with the requirements of Section 6.8 and then resumes employment with a Participating Employer, then that Participant’s Employer Matching Contributions Account and Employer Mandatory
Contributions Account balances shall be restored to the amount on the date of distribution; provided, however, the Participant repays to the Plan the full amount of the distribution attributable to Employer Matching Contributions and Employer
Mandatory Contributions before the earlier of five (5) years after the Participant’s Reemployment Commencement Date, or the date the Participant incurs five (5) consecutive one (1)-year Breaks in Service following the date of the
distribution. If a Participant is deemed to receive a distribution pursuant to paragraph (a) above, and the Participant resumes employment covered under the Plan before the date the Participant incurs five (5) consecutive one (1)-year
Breaks in Service, then, upon the Participant’s Reemployment Commencement Date, the Employer Matching Contributions Account and Employer Mandatory Contributions Account balances of the Participant shall be restored to the amount on the date of
such deemed distribution. 
 (e) Any amounts forfeited pursuant to this Section, Section 5.4 or Section 5.8 shall be
applied first, to restore Accounts pursuant to paragraph (d) above, second to reduce the Participating Employers’ obligations to make Employer Mandatory Contributions, third to reduce the Participating Employers’ obligation to make
Employer Matching Contributions, and fourth, to pay administrative expenses under the Plan.

 6.3 Early Retirement. Except as may be specified in one or more of the
Appendices, the Plan does not provide for any Early Retirement. If an Appendix provides for Early Retirement, then a Participant may retire as of any day on or after his or her Early Retirement. In such event, the Participant’s Account
shall be distributed in accordance with the applicable Appendix. 
 6.4 Normal Retirement. A Participant may
retire as of any day on or after his or her Normal Retirement. In such event, the Participant’s Account shall be distributed in accordance with Sections 6.8 through 6.12 or, if applicable, the Appendices. 

6.5 Disability. If a Participant terminates employment with a Participating Employer due to Disability, then the
Participant’s Account shall be distributed in accordance with Sections 6.8 through 6.12 or, if applicable, the Appendices. 

6.6 Death Benefits. If a Participant or former Participant dies before the entire vested balance of his or her Account has
been distributed, then the vested balance in his or her Account shall be paid to the Participant’s Beneficiary in accordance with Sections 6.8 through 6.12 or, if applicable, the Appendices. 

6.7 Termination of Employment. Following a Participant’s Severance Date, the Participant’s Account shall be
valued in accordance with the Administrator’s procedures, and distributed in accordance with Sections 6.8 through 6.12 or, if applicable, the Appendices. 
 6.8 Commencement of Distribution. 
 (a) Subject to Sections 6.9
through 6.12 below, following a Participant’s Severance Date, the Participant’s Account shall be distributed at a date designated by the Administrator, which designation (except as provided below) shall be determined in accordance with the
Administrator’s procedures. 
 (b) Effective for distributions made prior to March 22, 1999: 

(i) if the Participant’s vested Account balance does not exceed Five Thousand Dollars ($5,000) at the time of distribution (or at
the time any prior distribution), then the Participant shall receive a lump sum distribution of the entire vested portion of such Account balance and the nonvested portion shall be treated as a forfeiture; or 

(ii) if the Participant’s vested Account balance exceeds Five Thousand Dollars ($5,000) at the time of distribution (or at the time
of any prior distribution), then the Participant, or if the Participant is deceased, the Participant’s Spouse must consent in writing prior to the distribution. 

  
 35 









 (c) Effective for distributions made on or after March 22, 1999: 

(i) if the Participant’s vested Account balance does not exceed Five Thousand Dollars ($5,000) at the time of distribution, then
the Participant shall receive a lump sum distribution of the entire vested portion of such Account balance and the nonvested portion shall be treated as a forfeiture. In the event of such a mandatory lump sum distribution greater than $1,000, if the
Participant does not elect to have such distribution paid directly to an “eligible retirement plan” (as defined in Section 6.10) specified by the Participant in a direct rollover or to receive the distribution directly in the manner
set forth in the Plan, then the Plan Administrator will pay the distribution in a direct rollover to an individual retirement plan designated by the Plan Administrator; or 
 (ii) if the Participant’s vested Account balance exceeds Five Thousand Dollars ($5,000) at the time of distribution, then the Participant, or if the Participant is deceased, the Participant’s
Spouse, must consent in writing prior to the distribution. 
 (iii) Notwithstanding the foregoing, if a Participant has begun
to receive a distribution pursuant to an optional form of benefit under which at least one (1) scheduled periodic distribution is still payable, and if the value of the Participant’s vested Account balance exceeded Five Thousand Dollars
($5,000) at the time of the first distribution under that optional form of benefit, then the remaining value of the Participant’s vested Account balance may not be distributed without the written consent of the Participant, or if the
Participant is deceased, the Participant’s Spouse. 
 (d) If consent is required for a distribution, then the Participant,
or if the Participant is deceased, the Participant’s Spouse, must consent in writing to the distribution before it may be made and within the one hundred eighty (180)-day period ending on the first day on which all of the events have occurred
that entitle the Participant to such benefit (the “Annuity Starting Date”). If the Participant or, if applicable, the Participant’s Spouse, consents to the distribution, such distribution shall include all of the Participant’s
vested Account balance. If the Participant or, if applicable, the Participant’s Spouse, does not consent in writing to the distribution, then the Participant’s vested Account balance shall be held in the Trust until the maximum period
permitted under paragraph (e) below. If consent to a distribution is required hereunder, then at least thirty (30) days and not more than one hundred eighty (180) days prior to the Annuity Starting Date the Administrator shall provide
the Participant or, if applicable, the Participant’s Spouse with a notice of the right to elect immediate distribution or the right to defer distribution until the Participant’s Normal Retirement. 

(e) Unless the Participant elects otherwise by providing the Administrator with an executed written notice specifying the
Participant’s benefit under the Plan and the commencement date for distribution of the Participant’s Account, then distribution to a Participant shall commence no later than sixty (60) days following the close of the Plan Year in
which occurs the latest of: 
 (i) the date the Participant attains Normal Retirement; 

  
 36 









 (ii) the tenth (10th) anniversary of the date on which the Participant first commences
participation in the Plan; or 
 (iii) the Participant’s Severance Date. 

Notwithstanding the foregoing, the failure of a Participant (and/or, where applicable, the Participant’s Spouse) to consent to a distribution while
a benefit is immediately distributable within the meaning of this Section, shall be deemed to be an election to defer commencement of payment of any benefit. 
 (f) Spousal Consent shall be required for distributions. Notwithstanding the foregoing, and if the normal form of distribution specified in any of the Appendices is a Qualified Joint and Survivor Annuity,
then only the affected Participant (and not his or her Spouse) need consent to the commencement of a distribution in the form of a Qualified Joint and Survivor Annuity. Neither the consent of the Participant nor the Participant’s Spouse shall
be required to the extent that a distribution is required to satisfy Code Section 401(a)(9) or 415. In addition, upon termination of this Plan, to the extent the Plan does not offer an annuity option (purchased from a commercial provider) and
if the Employer does not maintain another defined contribution plan (other than an employee stock ownership plan as defined in Code Section 4975(e)(7)), then the Participant’s Account balance shall, without the Participant’s consent,
be distributed in a single lump sum to the Participant. However, if the Employer maintains another defined contribution plan (other than an employee stock ownership plan as defined in Code Section 4975(e)(7)), then the Participant’s
Account balance shall be transferred, without the Participant’s consent, to the other plan if the Participant does not consent to an immediate distribution. 
 (g) Notwithstanding anything to the contrary in the Plan, distribution of each Participant’s Account shall begin no later than the Participant’s Required Beginning Date regardless of whether the
Participant has consented to such a distribution. 
 (h) If a distribution is one for which Code Sections 401(a)(11) and 417 do
not apply, then such distribution may commence less than thirty (30) days after the notice required under Regulation Section 1.411(a)-11(c) is given, provided that: (i) the Administrator informs the Participant that the
Participant has a right to a period of at least thirty (30) days after receiving the notice to consider the decision of whether or not to elect a distribution (and, if applicable, a particular distribution option); and (ii) the
Participant, after receiving the notice, affirmatively elects a distribution and waives the thirty (30)-day period by written notice.

 6.9 Special Distribution Rules for Salary Deferral Contributions and Qualified
Nonelective Contributions. Salary Deferral Contributions and Qualified Nonelective Contributions, including Earnings thereon, shall also, as determined by the Board, be eligible for distribution upon: 

(a) the transfer by the Employer to any other employer of substantially all of the assets (within the meaning of Code
Section 409(d)(2)) used by the Employer in a trade or business, but only with respect to Participants who continue employment with the other employer who acquired such assets; or 

(b) the transfer by the Employer of such Employer’s interest in a subsidiary (within the meaning of Code Section 409(d)(2)) to
any other employer, but only with respect to Participants who continue employment with such transferred subsidiary, and so long as the Company maintains this Plan.

Retirement Plan for the benefit of a Distributee. 
 (ii) Distributee. “Distributee” means a Participant, a
Surviving Spouse of a deceased Participant, or a Spouse entitled to payment under a Qualified Domestic Relations Order. In addition, a Participant’s non-spouse Beneficiary is a Distributee with regard to the interest of a deceased Participant.

political subdivision of a state, or any agency or instrumentality of a state or political subdivision of a state and which agrees to separately account for amounts transferred into such plan from the Plan. The definition of “Eligible
Retirement Plan” also applies in the case of a distribution to a Surviving Spouse, or to a Spouse or former Spouse who is the alternate payee under a Qualified Domestic Relations Order, as defined in Section 7.7(iii) of the Plan. However,
in the case of an Eligible Rollover Distribution made with respect to a non-spouse Beneficiary, an “Eligible Retirement Plan” shall mean an individual retirement account described in Code Section 408(a) or an individual retirement
annuity described in Code Section 408(b) established for the purpose of receiving a distribution on behalf of the Participant’s or former Participant’s designated non-spouse Beneficiary. 

  
 38 









 (iv) Eligible Rollover Distribution. “Eligible Rollover Distribution”
means any distribution of all or any portion of the balance credited to the Account of a Distributee, except that an Eligible Rollover Distribution does not include: (A) 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; (B) any distribution to the extent such distribution is required under Code Section 401(a)(9); and (C) any hardship distribution described in Code Section 401(k)(2)(B)(i)(IV) (and the Participant may not elect
to have any portion of such a hardship distribution paid directly to an Eligible Retirement Plan). 
 (b) General Rule.
If the Distributee of any Eligible Rollover Distribution from the Plan elects to have all or a specified portion of the Eligible Rollover Distribution paid directly to an Eligible Retirement Plan, and specifies the Eligible Retirement Plan to which
the Eligible Rollover Distribution is to be paid, then the Eligible Rollover Distribution shall be paid to that Eligible Retirement Plan in a Direct Rollover. Notwithstanding the foregoing, any Eligible Rollover Distribution from a Roth Salary
Deferral Contributions Account under the Plan will only be made to: (i) another Roth elective deferral account under an applicable retirement plan described in Code Section 402A(e)(1); or (ii) a Roth IRA described in Code
Section 408A, and in the case of both subparagraphs (i) and (ii), only to the extent the rollover is permitted under the rules of Code Section 402(c). 
 (c) Notice. Not earlier than 180 days or later than 30 days before the payment of an eligible rollover distribution (or such other time as is prescribed by Treasury regulations or rulings), the
Company shall provide a written notice to the Distributee describing his or her rights under this Section and such other information required to be provided under Code Section 402(f).

distributions made in the Valuation Calendar Year after the Valuation Date. The Account balance for the Valuation Calendar Year includes any amounts rolled over or transferred to the Plan either in the Valuation Calendar Year or in the Distribution
Calendar Year if distributed or transferred in the Valuation Calendar Year. 
 (vi) Required Beginning

(A) Participants who are not Five Percent Owners. but who Attain Age 70 1/2 prior to January 1, 1996. The first day of April in the calendar year following the calendar year in which the Participant attains age
70 1/2. 

(B) Participants who are not Five Percent Owners and who Attain Age 70 1/2, between January 1, 1996 and December 31,1998. The first day of April in the calendar year following the calendar year in which the later of attainment of age

 (i) Required Beginning Date. The Participant’s entire interest will be distributed, or begin to be distributed, to the Participant no later than the Participant’s Required Beginning Date.

 (ii) Death of Participant Before Distributions Begin. If the Participant dies before distributions begin, the
Participant’s entire interest will be distributed, or begin to be distributed, no later than as follows: 
 (A) If the Participant’s Surviving Spouse is the Participant’s sole Designated Beneficiary, then except as provided in Section 6.12(e), distributions to the Surviving Spouse will begin by
December 31 of the calendar year immediately following the calendar year in which the Participant died, or by December 31 of the calendar year in which the Participant would have attained age 70 1/2, if later. 

(B) If the Participant’s Surviving Spouse is not the Participant’s sole Designated Beneficiary, then except as provided in
Section 6.12(e), distributions to the Designated Beneficiary will begin by December 31 of the calendar year immediately following the calendar year in which the Participant died. 

(C) If there is no Designated Beneficiary as of September 30 of the year following the year of the Participant’s death, the
Participant’s entire interest will be distributed by December 31 of the calendar year containing the fifth anniversary of the Participant’s death. 
 (D) If the Participant’s Surviving Spouse is the Participant’s sole Designated Beneficiary and the Surviving Spouse dies after the Participant but before distributions to the Surviving Spouse
begin, this Section 6.12(b)(ii), other than Section 6.12(b)(ii)(A), will apply as if the Surviving Spouse were the Participant. 
 If
distributions under an annuity purchased from an insurance company irrevocably commence to the Participant before the Participant’s Required Beginning Date (or to the Participant’s Surviving Spouse before the date distributions are
required to begin to the Surviving Spouse under Section 6.12(b)(ii)(A)), the date distributions are considered to begin is the date distributions actually commence. 

  
 41 









 (iii) Forms of Distribution. Unless the Participant’s interest is distributed
in the form of an annuity purchased from an insurance company or in a single sum on or before the Required Beginning Date, as of the first Distribution Calendar Year distributions will be made in accordance with Sections 6.12(c) and 6.12(d). If the
Participant’s interest is distributed in the form of an annuity purchased from an insurance company, distributions thereunder will be made in accordance with the requirements of Code Section 401(a)(9) and the Treasury Regulations.

 (c) Required Minimum Distributions During Participant’s Lifetime. 

(i) Amount of Required Minimum Distribution For Each Distribution Calendar Year. During the Participant’s lifetime, the
minimum amount that will be distributed for each Distribution Calendar Year is the lesser of the quotient obtained by dividing the Participant’s Benefit by the distribution period in the Uniform Lifetime Table set forth in Regulation
Section 1.401(a)(9)-9, using the Participant’s age as of the Participant’s birthday in the Distribution Calendar Year, or if the Participant’s sole Designated Beneficiary for the Distribution Calendar Year is the
Participant’s Spouse, the quotient obtained by dividing the Participant’s Benefit by the number in the Joint and Last Survivor Table set forth in Regulation Section 1.401(a)(9)-9, using the Participant’s and Spouse’s
attained ages as of the Participant’s and Spouse’s birthdays in the Distribution Calendar Year. 
 (ii) Lifetime
Required Minimum Distributions Continue Through Year of Participant’s Death. Required minimum distributions will be determined under this Section 6.12(c) beginning with the first Distribution Calendar Year and up to and including the
Distribution Calendar Year that includes the Participant’s date of death. 
 (d) Required Minimum Distributions After
Participant’s Death. 
 (i) Death On or After Date Distributions Begin - Participant Survived by Designated
Beneficiary. If the Participant dies on or after the date distributions begin and there is a Designated Beneficiary, the minimum amount that will be distributed for each Distribution Calendar Year after the year of the Participant’s death
is the quotient obtained by dividing the Participant’s Benefit by the longer of the remaining Life Expectancy of the Participant or the remaining Life Expectancy of the Participant’s Designated Beneficiary, determined as follows:

 (A) The Participant’s remaining Life Expectancy is calculated using the age of the Participant in the year of death,
reduced by one for each subsequent year. 
 (B) If the Participant’s Surviving Spouse is the Participant’s sole
Designated Beneficiary, the remaining Life Expectancy of the Surviving Spouse is calculated for each Distribution Calendar Year after the year of the 

  
 42 









 
Participant’s death using the Surviving Spouse’s age as of the Spouse’s birthday in that year. For Distribution Calendar Years after the year of the Surviving Spouse’s death,
the remaining Life Expectancy of the Surviving Spouse is calculated using the age of the Surviving Spouse as of the Spouse’s birthday in the calendar year of the Spouse’s death, reduced by one for each subsequent calendar year. 

(C) If the Participant’s Surviving Spouse is not the Participant’s sole Designated Beneficiary, the Designated
Beneficiary’s remaining Life Expectancy is calculated using the age of the Beneficiary in the year following the year of the Participant’s death, reduced by one for each subsequent year. 

(ii) Death On or After Date Distributions Begin - No Designated Beneficiary. If the Participant dies on or after the date
distributions begin and there is no Designated Beneficiary as of September 30 of the year after the year of the Participant’s death, the minimum amount that will be distributed for each Distribution Calendar Year after the year of the
Participant’s death is the quotient obtained by dividing the Participant’s Benefit by the Participant’s remaining Life Expectancy calculated using the age of the Participant in the year of death, reduced by one for each subsequent
year. 
 (iii) Death Before Date Distributions Begin - Participant Survived by Designated Beneficiary. Except as
provided in Section 6.12(e), if the Participant dies before the date distributions begin and there is a Designated Beneficiary, the minimum amount that will be distributed for each Distribution Calendar Year after the year of the
Participant’s death is the quotient obtained by dividing the Participant’s Benefit by the remaining Life Expectancy of the Participant’s Designated Beneficiary, determined as provided in Sections 6.12(d)(i) and (ii). 

(iv) Death Before Date Distributions Begin - No Designated Beneficiary. If the Participant dies before the date distributions
begin and there is no Designated Beneficiary as of September 30 of the year following the year of the Participant’s death, distribution of the Participant’s entire interest will be completed by December 31 of the calendar year
containing the fifth anniversary of the Participant’s death. 
 (v) Death Before Date Distributions Begin - Death of
Surviving Spouse Before Distributions to Surviving Spouse Are Required to Begin. If the Participant dies before the date distributions begin, the Participant’s Surviving Spouse is the Participant’s sole Designated Beneficiary, and the
Surviving Spouse dies before distributions are required to begin to the Surviving Spouse under Section 6.12(b)(ii)(A), Section 6.12(d)(iii) will apply as if the Surviving Spouse were the Participant. 

(e) Election to Allow Participants or Beneficiaries to Elect 5-Year Rule. Participants or Beneficiaries may elect on an individual
basis whether the 5-year rule or the life expectancy rule in Sections 6.12(b)(ii)(A), 6.12(b)(ii)(B), 6.12(d)(iii) and 

  
 43 









 
6.12(d)(iv) applies to distributions after the death of a Participant who has a Designated Beneficiary. The election must be made no later than the earlier of September 30 of the calendar
year in which distribution would be required to begin under Section 6.12(b)(ii), or by September 30 of the calendar year which contains the fifth anniversary of the Participant’s (or, if applicable, Surviving Spouse’s) death. If
neither the Participant nor Beneficiary makes an election, distributions will be made in accordance with Sections 6.12(b)(ii)(A), 6.12(b)(ii)(B), 6.12(d)(iii) and 6.12(d)(iv). 
 6.13 Distribution to Minor or Incompetent. If any individual to whom a benefit is payable under the Plan is a minor, or if the Administrator determines that any individual to whom a benefit
is payable under the Plan is incompetent to receive such payment or to give a valid release thereof, then the Administrator may direct that such distribution be paid to the legal guardian, or if none, to a parent of such minor or incompetent, or a
responsible adult with whom the minor or incompetent resides, or to a custodian for a minor under the Uniform Transfers to Minors Act (or other statutes of similar import), if permitted by the laws of the state in which the minor or incompetent
resides. Payment to the legal guardian, parent or custodian of a minor Beneficiary shall fully discharge the Trustee, Administrator and Plan from liability on account thereof. 
 6.14 Beneficiary Designation. If the Participant is married, the Beneficiary shall be the Participant’s Surviving Spouse and no written designation is required. However, a Participant
may designate a Beneficiary other than the Participant’s Spouse; provided, however: (a) the Participant’s Spouse consents in writing to such designation and to the form thereof (on a form acceptable to the Administrator);
(b) such Beneficiary designation may not be changed without Spousal Consent (or the consent of the Spouse expressly permits changes in the beneficiary designation by the Participant without any requirement of further consent by the Spouse); and
(c) the Spouse’s consent acknowledges the effect of such Beneficiary designation and is witnessed by a Plan representative or a notary public. Such Spousal Consent shall not be required if it is established to the satisfaction of the
Administrator that the consent required under the preceding sentence cannot be obtained because there is no Spouse, the Spouse cannot be located, or such other circumstances as the Secretary of the Treasury may by Regulations prescribe. If, at the
time of the Participant’s death, the Participant has no Surviving Spouse or designated Beneficiary, then the Beneficiary shall be the individual representative of the Participant’s estate. A Participant’s Beneficiary shall be bound by
the terms and conditions of the Plan. 
 6.15 Spousal Consent. 

(a) Requirement of Consent. Each Participant shall obtain the consent of his or her Spouse, if any (“Spousal Consent”),
to an in-service withdrawal, beneficiary designation, loan, and/or distribution. Spousal Consent shall not be required if the Participant establishes to the satisfaction of the Administrator that the consent of the Spouse cannot be obtained because
there is no Spouse or the Spouse cannot be located. 

  
 44 









 
The consent of the Participant’s Spouse shall not be required to the extent that a distribution is required to satisfy Code Section 401(a)(9) or 415. A Spouse’s consent shall not
be valid with respect to any other Spouse. 
 (b) Form of Consent. 

(i) Spousal Consent shall be made in writing and witnessed by a Plan representative or notary public. The Spouse shall have the right,
which can be waived, to limit his or her consent only to a specific form of distribution or withdrawal, beneficiary designation, or loan. If the Spouse elects to waive his or her right to any of the above, then the Spouse shall acknowledge the
effect of such waiver, including that: (A) the Spouse had the right to limit his or her consent; (B) the Spouse voluntarily waived this right; and (C) the Spouse understands the effect such consent has upon any benefits otherwise
payable to him or her under the Plan. 
 (ii) Unless the consent of the Spouse expressly permits the Participant to elect any
and all future distributions, withdrawals, loans, or beneficiary designations without a requirement of further consent by that Spouse, then the Spouse’s consent shall be limited to that specific election. Spousal Consent may be revoked at any
time prior to the date on which a distribution is actually made. 
 (c) Timing of Consent. Spousal Consent to an
in-service withdrawal or distribution shall be made within the one hundred eighty (180) days preceding the date of the in-service withdrawal or distribution. Spousal Consent to a loan shall be made within the ninety (90) days preceding the
date of the loan. 
 6.16 Location of Participant or Beneficiary Unknown. If a Participant or Beneficiary who is
entitled to a distribution cannot be located and the Administrator has made reasonable efforts to locate the Participant or Beneficiary, then the Participant’s or Beneficiary’s interest shall be forfeited and used: first, to restore
any amounts previously forfeited under this Section and Section 6.2(d); second, to pay administrative expenses of the Plan for the Plan Year in which the forfeiture occurs; third, to offset the Employer’s obligation to make
Employer Mandatory Contributions for the Plan Year in which the forfeiture occurs; and fourth, to allocate as Employer Matching Contributions for the Plan Year in which the forfeiture occurs. If the Participant or Beneficiary makes a written
claim for the Account subsequent to the forfeiture, then the Employer shall cause the Account to be reinstated. 
 6.17
Hardship Distributions. 
 (a) Upon hardship of a Participant, the Trustee shall, upon the direction of the
Administrator, make a distribution from the Participant’s Rollover Contributions Account, Salary Deferral Contributions Account (not including earnings), Roth Salary Deferral Contributions Account (not including earnings) and any vested
interest in his or 

  
 45 









 
her Employer Matching Contributions Account, in that order. A Participant shall be entitled to a hardship distribution only if the distribution is both (i) made on account of an immediate
and heavy financial need of the Participant (as defined in paragraph (b)), and (ii) is necessary to satisfy such financial need (as defined in paragraph (c)). The Participant shall furnish the Administrator with satisfactory proof that the
hardship distribution meets the requirements of paragraphs (b) and (c). 
 (b) An immediate and heavy financial need shall
be deemed to include any one or more of the following: 
 (i) expenses incurred or necessary for medical care, described in
Code Section 213(d), of the Employee, the Employee’s spouse or dependents; 
 (ii) the purchase (excluding mortgage
payments) of a principal residence for the Employee; 
 (iii) payment of tuition and related educational fees for the next 12
months of post-secondary education for the Employee, the Employee’s Spouse, children or dependents; 
 (iv) payments
necessary to prevent the eviction of the Employee from, or a foreclosure on the mortgage of, the Employee’s principal residence; 
 (v) payments for funeral or burial expenses for the Employee’s deceased parent, Spouse, child or dependent; and 
 (vi) expenses to repair damage to the Employee’s principal residence that would qualify for a casualty loss deduction under Code Section 165 (determined without regard to whether the loss
exceeds 10-percent of adjusted gross income). 
 (c) A distribution shall be considered as necessary to satisfy an immediate and
heavy financial need of the Participant only if: 
 (i) the Participant has obtained all distributions, other than hardship
distributions, and all nontaxable loans under all plans maintained by the Employer; 
 (ii) the Participant is prohibited from
making Salary Deferral Contributions to this Plan for six (6) months after the receipt of the hardship distribution. In addition, the Participant must agree to stop making elective contributions and employee contributions to all other plans of
the Employer (to the extent permissible under the terms of such plan) for at least six (6) months after receipt of the hardship distribution; 

  
 46 









 (iii) the distribution is not in excess of the amount of an immediate and heavy financial
need (including amounts necessary to pay any federal, state or local income taxes or penalties reasonably anticipated to result from the distribution); and 
 (iv) all plans maintained by the Employer limit the Participant’s elective contributions for the taxable year immediately following the taxable year of the hardship distribution to the applicable
limit under Code Section 402(g) for such taxable year, less the amount of such Participant’s elective contributions for the taxable year of the hardship distribution. 

(d) A Participant shall be required to obtain Spousal Consent prior to receiving a hardship distribution. 

(e) If a Participant receives a distribution under this Section from his or her partially vested Employer Matching Contributions
Account, at any relevant time following the hardship distribution, the Participant’s vested interest (“X”) in his or her Employer Matching Contributions Account shall be calculated in accordance with the following formula: X = P (AB +
D) - D. For purposes of the formula in the preceding paragraph, “P” is the Participant’s current vesting percentage at the relevant time, “AB” is the value of the Participant’s Employer Matching Contributions Account at
the relevant time, and “D” is the amount of the distribution. 
 6.18 Loans. 

(a) The Administrator may direct the Trustee to make loans to Participants who are Employees and/or Beneficiaries who are parties in
interest (as defined in ERISA Section 3(14)), provided that: 
 (i) such loans are available to all such Participants and
Beneficiaries on a reasonably equivalent basis; 
 (ii) such loans are not made available to Highly Compensated Employees,
officers or shareholders in an amount greater than the amount made available to other Employees; 
 (iii) such loans bear a
reasonable rate of interest; 
 (iv) such loans are adequately secured; and 

(v) a Participant’s or Beneficiary’s aggregate outstanding loans shall not exceed the lesser of (A) fifty percent
(50%) of the present value of the Participant’s or Beneficiary’s vested Account, or (B) Fifty Thousand Dollars ($50,000) (reduced by the excess, if any, of (1) the highest principal amount of the aggregate outstanding loans
at any time during the immediately preceding twelve (12) months, over (2) the aggregate principal amount outstanding under such loans on the date the new loan is made). 

  
 47 









 (b) A married Participant shall obtain Spousal Consent in order to use his or her Account
balance as security for the loan. 
 (c) In the event of default, foreclosure on the note and attachment of security shall not
occur until a distributable event occurs under the Plan. 
 (d) Notwithstanding any contrary provision of this Plan, the portion
of the Participant’s vested Account balance used as a security interest held by the Plan by reason of a loan outstanding to the Participant shall be taken into account for purposes of determining the amount of the Account balance payable at the
time of distribution, but only if the reduction is used as repayment of the loan. If less than one hundred percent (100%) of the Participant’s vested Account balance (determined without regard to the preceding sentence) is payable to the
Surviving Spouse, then the Account balance shall be adjusted by first reducing the vested Account balance by the amount of the security used as repayment of the loan, and then determining the benefit payable to the Surviving Spouse. 

(e) All such loans shall be subject to ERISA, the Code, and such terms and conditions not inconsistent therewith (and subject to this
Section) as determined by the Administrator. 
 (f) The Administrator shall adopt written policies and guidelines which
establish and detail the terms of Plan loans hereunder, and which shall be deemed a part of this Plan. Such policies and guidelines may be amended by the Administrator from time to time. 

(g) Notwithstanding the above, effective December 12, 1994, loan repayments for Participants on military leave will be suspended
under this Plan as permitted under Code Section 414(u)(4). 
 6.19 In-Service Withdrawals at and After Normal
Retirement. 
 (a) A Participant may, once in every twelve (12)-consecutive-month period, withdraw all or a portion of
the vested portion of his or her Accounts (excluding amounts held in the Participant’s Pension Plan Account and FaAA Plan Account, if any) at any time subsequent to attainment of Normal Retirement; provided, however, that a married Participant
shall obtain Spousal Consent for such withdrawal. 
 (b) A Participant may make separate withdrawal elections for his Roth
Salary Deferral Contributions Account and his Salary Deferral Contributions Account. 

  
 48 









 (c) If a Participant receives a distribution under this Section from his or her
partially vested Employer Mandatory Contributions Account, and/or Employer Matching Contributions Account at any relevant time following the distribution, the Participant’s vested interest in his or her Employer Mandatory Contributions Account
and/or Employer Matching Contributions Account (“X”) shall be calculated in accordance with the following formula: X = P (AB + D) - D. For purposes of this formula, “P” is the Participant’s current vesting percentage at the
relevant time, “AB” is the value of the Participant’s Employer Matching Contributions Account and/or Employer Mandatory Contributions Account at the relevant time, and “D” is the amount of the distribution. 

6.20 Form of Distribution. Distributions shall be in the form of cash, except as otherwise provided in the Appendices
attached hereto.

Committee shall thereupon give notice that a vacancy exists in the office of such Member by prominently posting written notice thereof at places customarily used by the Company for employer-employee notices. Any Participant eligible to vote in the
election of the Member may place a name in nomination by notifying the Committee in writing within ten (10) days of the date on which such notice is posted. At the expiration of such ten (10) day period, the Committee shall prepare a
ballot in such form as it shall deem appropriate containing the names of each person who has been nominated and who has indicated to the Committee his or her willingness to serve as a Member; provided, however, that the Committee shall not place on
the ballot the name of any person who is prohibited from serving under ERISA Section 411 or any other provision of applicable law or of the Plan or the Trust Agreement. The Committee may require any individual who desires to serve as a Member
to furnish such information as it may reasonably require in order to satisfy the requisites of the preceding sentence.

ten (10) nor more than fifteen (15) days after the date of distribution. In the case of ballots distributed by electronic mail, distribution shall be deemed to occur when the ballots are transmitted via electronic mail. In the case of
ballots distributed by mail, distribution shall be deemed to occur on the date of mailing. A ballot shall be deemed to be cast on the date and at the time of its actual receipt by the Committee in the manner and at the location designated on the

Members. However, no Member shall vote on any question in which he or she has any direct or indirect interest, unless such direct or indirect interest results merely from his or her being a Participant in the Plan and is not materially different
from the interest that other Participants in the Plan have in the question. In the event that any vote shall result in a tie, such tie shall be broken by the decision of Member A.

(whether or not tax-qualified) of the Company or any related company, unless the portion of the successor plan that consists of the transferred or merged accounts is subject to restrictions that are identical (except for appropriate
Section numbering and cross-reference changes) to those imposed by this Section 7.6. 
 7.7 Domestic Relations
Orders. 
 (a) Definitions. 
 (i) Alternate Payee. “Alternate Payee” means any Spouse, former Spouse, child or other dependent (within the meaning of Code Section 152) of a Participant who is recognized by a
Domestic Relations Order as having a right to receive any immediate or deferred payment of all or a portion of the balance credited to a Participant’s Account under the Plan. 

(ii) Domestic Relations Order or Order. “Domestic Relations Order” or “Order” means any judgment, decree or
order (including approval of a property settlement agreement) which provides or otherwise conveys, pursuant to applicable state domestic relations laws (including community property laws), child support, alimony payments or marital property rights
to an Alternate Payee. 

  
 54 









 (iii) Qualified Domestic Relations Order. “Qualified Domestic Relations
Order” means any Domestic Relations Order that meets the following requirements: 
 (A) such Order establishes (or
otherwise recognizes the existence of) the right of an Alternate Payee to receive all or a portion of the vested balance credited to a Participant’s Account under the Plan; 

(B) such Order specifies (1) the name and last known mailing address of the Participant, (2) the name and last known mailing
address of each Alternate Payee covered by such Order, (3) the amount or percentage of the Participant’s vested account balance under the Plan payable to each such Alternate Payee or the manner in which such amount or percentage is to be
calculated, and (4) any other requirement set forth in ERISA Section 206(d)(3) or Code Section 414(p); and 

(C) such Order does not require the Plan to (1) provide any type or form of benefit or option not otherwise available to the
Participant under the Plan, (2) provide increased benefits not otherwise payable to the Participant under the Plan, or (3) pay benefits to an Alternate Payee which are required to be paid to another Alternate Payee pursuant to any
Qualified Domestic Relations Orders previously issued with respect to the Participant’s Account under the Plan. 
 (b)
Notification. Upon receipt of a Domestic Relations Order, the Administrator shall promptly notify the affected Participant and each Alternate Payee of the receipt of such Order and the procedures established by the Administrator for
determining whether such Order satisfies the requirements for recognition as a Qualified Domestic Relations Order. Such notice shall also advise such Participant and Alternate Payee of his or her right to designate a representative to receive
communications from the Administrator concerning the disposition of the Domestic Relations Order. Within a reasonable time after providing such notification, the Administrator shall, pursuant to such procedures, determine whether or not the Order is
a Qualified Domestic Relations Order and shall notify the Participant and each Alternate Payee (or his or her representative) of such determination. 
 (c) Procedures. The Administrator shall establish reasonable procedures for determining the qualified status of Domestic Relations Orders and for effecting distributions pursuant to all such Orders
which are determined to be Qualified Domestic Relations Orders. 
 (d) Payment. 

(i) During the period in which the qualified status of a Domestic Relations Order is pending, the Administrator shall defer the payment
of all Plan benefits affecting the Participant which are in dispute and shall separately account for all amounts which would otherwise be payable to the Alternate Payee (the “Segregated Amounts”) during such period were the Order
determined to be a Qualified Domestic Relations Order. 

  
 55 









 (ii) If the Administrator determines, within eighteen (18) months after the date the
first payment to the Alternate Payee would otherwise be required to be made pursuant to the terms of the Order, that such Order is a Qualified Domestic Relations Order, then the Administrator shall establish a separate Account to hold the Segregated
Amounts (including any Earnings thereon) on behalf of such Alternate Payee and such Alternate Payee shall then be treated as a Participant for purposes of such Account. To the extent such Qualified Domestic Relations Order provides for the payment
of the entire balance of the Segregated Amounts (including any Earnings thereon) to the Alternate Payee prior to the Participant’s Severance Date, then the Administrator shall make such payment in accordance with such Order, even though the
affected Participant’s Severance Date has not occurred. Such payment shall be made as if the Participant’s Severance Date occurred on the date on which benefits are to enter pay status under the Order. Notwithstanding the foregoing,
payment to the Alternate Payee shall not be deferred beyond the date distribution to the Participant or (in the event of death) his or her Beneficiary is made or commenced. 
 (iii) If the Administrator determines, within such eighteen (18) month period under paragraph (ii) above, that such Order is not a Qualified Domestic Relations Order, or if the qualified status
of such Order cannot be determined prior to the expiration of such eighteen (18) month period, then the Administrator shall authorize the payment of the Segregated Amounts (including any Earnings thereon) to the individual or individuals who
would have been entitled to receive such Segregated Amounts under the Plan had the Order not been issued. If such individual is the Participant, then the previously Segregated Amounts shall remain part of the Trust and shall not be distributed until
the Participant becomes entitled to benefits under the Plan in accordance with the provisions of Article VI or any applicable Appendix. Should there be a subsequent determination that the Order is in fact a Qualified Domestic Relations Order,
then such determination shall be applied on a prospective basis only. 
 (e) Hold Procedures. Notwithstanding any
contrary Plan provision, prior to the receipt of a Domestic Relations Order, the Administrator may, place a hold (as defined below) upon such portion of a Participant’s Account, at such time and for such reasonable period of time as the
Administrator may determine, if the Administrator receives notice that (1) a Domestic Relations Order is being sought by the Participant, his or her Spouse, former Spouse, child or other dependent (within the meaning of Code Section 152),
and (2) the Participant’s Account is likely to be a source of payment under such Order. For purposes of this paragraph, a “hold” means that no withdrawals, loans or other distributions may be made with respect to a
Participant’s Account. The Administrator shall notify a Participant if a hold is placed upon his or her Account pursuant to this paragraph.

 ARTICLE XI. 
 AMENDMENT, TERMINATION OR MERGER 
 11.1 Amendment.

 (a) The Company shall have full power and authority to amend the provisions of the Plan, subject to Section 7.6(g), for
any reason, at any time, either prospectively or retroactively, to such extent and in such manner as the Company shall deem advisable, in accordance with its normally established procedures. The Company may delegate such power, subject to
Section 7.6(g), in whole or in part, to one or more committees (comprised of officers or other managerial personnel of the Employer) to whom administrative responsibilities may be delegated under the Plan. 

(b) The Board delegates to the Committee or any individual or committee appointed by the Administrator the full power and authority to
adopt and to provide a certificate evidencing the execution of any amendment to the Plan, subject to Section 7.6(g), which satisfies one of the following requirements:

 (ii) the
amendment is designed to bring the Plan into compliance with applicable law; 
 (iii) the amendment is designed to ensure the

Employer. 
 (c) An amendment shall become effective, in accordance with its terms as to all Participants and all other persons
having or claiming an interest under the Plan, upon the effective date specified in the instrument evidencing such amendment. However, no such amendment shall operate to: (i) cause any part of the Trust to revert to or be recoverable by the
Employer or to be used for, or diverted to, purposes other than the exclusive benefit of Participants and their Beneficiaries (or for defraying the reasonable administrative expenses of the Plan); (ii) reduce the then outstanding balances in
the Accounts of Participants; (iii) cause or effect any discrimination in favor of Highly Compensated Employees; (iv) change the duties, responsibilities or liabilities of the Trustee hereunder without the written consent of such Trustee;
or (v) affect, reduce or eliminate any benefits which are protected benefits pursuant to Code Section 411(d)(6). 

  
 61 









 11.2 Termination. The Company may terminate this Plan at any time for any
reason by resolution adopted by the Board, but the Trust may not thereby be diverted from the exclusive benefit of the Participants, their Beneficiaries, survivors or estates (other than for defraying the reasonable administrative expenses of the
Plan), nor revert to the Employer, nor may any change be made to a previously allocated contribution other than to correct a contribution that was improperly allocated. Upon termination or partial termination of the Plan or complete discontinuance
of Employer Contributions under the Plan, the Accounts of each affected Participant shall be nonforfeitable. The Administrator shall distribute each Participant’s Accounts to the Participant pursuant to Sections 6.8 through 6.11 as soon as
administratively feasible after the termination (to the extent such distribution is permitted under applicable law). 
 11.3
Merger. 
 (a) The Board delegates to the Administrator, or any individual or committee appointed by the
Administrator the full power and authority, subject to Section 7.6(g), to effect from time to time, upon such terms and conditions deemed appropriate, the merger of any and all tax-qualified defined contribution plans and related tax-exempt
trusts maintained by entities acquired by the Company into the Plan and Trust and to take any and all such action, and prepare, execute, and deliver all such documents as may be necessary or advisable to effect any and all such plan and trust
mergers. 
 (b) Except as otherwise provided in Section 7.6(g), nothing contained herein shall prevent the merger or
consolidation of the Plan with, or transfer of assets or liabilities of the Plan to, another plan meeting the requirements of Code Section 401(a) or the transfer to the Plan of assets or liabilities of another such plan so qualified under
the Code. Any such merger, consolidation or transfer shall be accompanied by the transfer of such existing records and information as may be necessary to properly allocate such assets among Participants, including without limitation any tax or other
information necessary for the Participants or persons administering the plan which is receiving such assets. The terms of such merger, consolidation or transfer must be such that (if the Plan had then terminated), the requirements of this
Article would be satisfied and each Participant (or, if applicable, his or her Beneficiary) would receive a benefit immediately after the merger, consolidation or transfer equal to or greater than the benefit he or she would have received if
the Plan had terminated immediately before the merger, consolidation or transfer. Notwithstanding any provision in this Plan to the contrary, any amounts transferred to the Plan as a result of such merger, consolidation or transfer shall, to the
extent the benefits accrued under the transferor plan are protected benefits under Code Section 411(d)(6) (“Protected Benefits”), be preserved under this Plan, and shall not in any way be affected, reduced or eliminated by Plan
amendment, other than as legally required or permitted.

the Trustee shall set aside from the Trust such cash, securities and other property as it shall deem to be equal in value to the Participating Employer’s equitable share. If the Plan is to be terminated with respect to the Participating
Employer, then the amount set aside shall be administered according to Article IX and the Trust Agreement. If the Plan is not to be terminated with respect to the Participating Employer, then the Trustee shall turn over the Participating
Employer’s equitable share to a trustee designated by the Participating Employer, and the cash, securities and other property shall thereafter be held and invested as a separate trust of the Participating Employer and shall be used and applied
according to the terms of a new trust agreement between the Participating Employer and the trustee so designated. Neither the segregation of the Trust assets upon the withdrawal of a Participating Employer nor the execution of a new trust agreement
shall operate to permit any part of the assets of the Trust to be used for or diverted to purposes other than for the exclusive benefit of Participants and Beneficiaries (or for defraying the reasonable administrative expenses of the Plan).

 ARTICLE XIV. 
 TOP-HEAVY PROVISIONS 
 14.1 Purpose. This
Article is intended to insure that the Plan complies with Code Section 416. If the Plan is or becomes Top-Heavy in any Plan Year, the provisions of this Article shall supersede any conflicting provision in the Plan. 

14.2 Definitions. For purposes of this Article, the following definitions shall apply: 

(a) Determination Date. “Determination Date” means for any Plan Year, the last day of the preceding Plan Year.

 (b) Determination Period. “Determination Period” means the Plan Year containing the Determination Date and
the four (4) preceding Plan Years. 
 (c) Key Employee. “Key Employee” means any Employee or former
Employee (including any deceased Employee) who at any time during the Plan Year that includes the Determination Date was an officer of the Employer having annual compensation greater than $130,000 (as adjusted under Code Section 416(i)(1) for
Plan Years beginning after December 31, 2002), a 5-percent owner of the Employer, or a 1- percent owner of the Employer having annual compensation of more than $150,000. For this purpose, “annual compensation” means compensation
within the meaning of Code Section 415(c)(3). The determination of who is a Key Employee will be made in accordance with Code Section 416(i)(1) and the applicable regulations and other guidance of general applicability issued thereunder.

 (d) Non-Key Employee. “Non-Key Employee” means any Employee who is not a Key Employee, including Employees
who are former Key Employees. 
 (e) Permissive Aggregation Group. “Permissive Aggregation Group” means the
Required Aggregation Group of plans, plus any other plan or plans of the Employer which, when considered as a group with the Required Aggregation Group, would continue to satisfy the requirements of Code Sections 401(a)(4) and 410. 

(f) Required Aggregation Group. “Required Aggregation Group” means: 

(i) each tax-qualified plan of the Employer in which at least one (i) Key Employee participates or participated at any time during
the Determination Period (regardless of whether the plan has terminated); and 

  
 66 









 (ii) any other tax-qualified plan of the Employer which enables a plan described in
paragraph (i) above to meet the requirements of Code Section 401(a)(4) or 410. 
 (g) Top-Heavy Plan.
“Top-Heavy Plan” means this Plan, if for any Plan Year any of the following conditions exists: 
 (i) the Top-Heavy
Ratio for this Plan exceeds sixty percent (60%) and this Plan is not part of any Required Aggregation Group or Permissive Aggregation Group of plans; 
 (ii) this Plan is a part of a Required Aggregation Group of plans but not part of a Permissive Aggregation Group and the Top-Heavy Ratio for the Required Aggregation Group exceeds sixty percent (60%); or

 (iii) this Plan is a part of a Required Aggregation Group and part of a Permissive Aggregation Group of plans and the
Top-Heavy Ratio for the Permissive Aggregation Group exceeds sixty percent (60%). 
 (h) Top-Heavy Ratio. “Top-Heavy
Ratio” means: 
 (i) if the Employer maintains one or more defined contribution plans (including any simplified employee
pension plan) and the Employer has not maintained any defined benefit plan which during the five (5) year period ending on the Determination Date(s) has or has had accrued benefits, the Top-Heavy Ratio for this Plan alone or for the Required or
Permissive Aggregation Group as appropriate is a fraction, the numerator of which is the sum of the Account balances of all Key Employees as of the Determination Date(s) (including any part of any Account balance distributed in the five
(5) year period ending on the Determination Date(s)), and the denominator of which is the sum of Account balances (including any part of any Account balance distributed in the five (5)-year period ending on the Determination Date(s)), both
computed in accordance with Code Section 416. Both the numerator and denominator of the Top-Heavy Ratio are increased to reflect any contribution not actually made as of the Determination Date, but which is required to be taken into account on
that date under Code Section 416. 
 (ii) if the Employer maintains one or more defined contribution plans (including any
simplified employee pension plan) and the Employer maintains or has maintained one or more defined benefit plans which during the five (5) year period ending on the Determination Date(s) has or has had any accrued benefits, the Top-Heavy Ratio
for any Required or Permissive Aggregation Group as appropriate is a fraction, the numerator of which is the sum of Account balances under the aggregated defined contribution plan or plans for all Key Employees, determined in accordance with
paragraph (i) above, and the present value of accrued benefits under the aggregated 

  
 67 









 
defined benefit plan or plans for all Key Employees as of the Determination Date(s), and the denominator of which is the sum of Account balances under the aggregated defined contribution plan or
plans for all participants, determined in accordance with paragraph (i) above, and the present value of accrued benefits under the defined benefit plan or plans for all participants as of the Determination Date(s), all determined in accordance
with Code Section 416. The accrued benefits under a defined benefit plan in both the numerator and denominator of the Top-Heavy Ratio are increased for any distribution of an accrued benefit made in the five (5)-year period ending on the
Determination Date. 
 (iii) for purposes of paragraphs (i) and (ii) above, the value of Account balances and the
present value of accrued benefits shall be determined as of the most recent Valuation Date that falls within or ends with the twelve (12) month period ending on the Determination Date, except as provided in Code Section 416 for the first
and second plan years of a defined benefit plan. The Account balances and accrued benefits of a participant (1) who is not a Key Employee but who was a Key Employee in a prior year, or (2) who has not been credited with at least one
(1) Hour of Service with any Employer maintaining the Plan at any time during the five (5)-year period ending on the Determination Date shall be disregarded. The calculation of the Top-Heavy Ratio, and the extent to which distributions,
rollovers, and transfers are taken into account shall be made in accordance with Code Section 416. When aggregating plans, the value of Account balances and accrued benefits shall be calculated with reference to the Determination Dates that
fall within the same calendar year. 
 The accrued benefit of a Participant other than a Key Employee shall be determined under
(1) the method, if any, that uniformly applies for accrual purposes under all defined benefit plans maintained by the Employer, or (2) if there is no such method, as if such benefit accrued not more rapidly than the slowest accrual rate
permitted under the fractional rule of Code Section 411(b)(1)(C). 
 (i) Valuation Date. “Valuation
Date” means the last day of the Plan Year, as of which Account balances or accrued benefits are valued for purposes of calculating the Top-Heavy Ratio. 
 14.3 Determination of Present Values and Amounts. This Section 14.3 shall apply for purposes of determining the present values of accrued benefits and the amounts of account balances of
Employees as of the determination date. 
 (a) Distributions during Year Ending on the Determination Date. The present
values of accrued benefits and the amounts of account balances of an Employee as of the Determination Date shall be increased by the distributions made with respect to the Employee under the Plan and any plan aggregated with the Plan under Code
Section 416(g)(2) during the 1-year period ending on the Determination Date. The preceding sentence shall also apply to distributions under a terminated plan which, had it not been terminated, would have been aggregated with the Plan under Code


  
 68 









 
Section 416(g)(2)(A)(i). In the case of a distribution made for a reason other than separation from service, death, or disability, this provision shall be applied by substituting
“5-year period” for “1-year period.” 
 (b) Employees Not Performing Services During Year Ending on the
Determination Date. The accrued benefits and accounts of any individual who has not performed services for the Employer during the 1-year period ending on the Determination Date shall not be taken into account 

14.4 Minimum Allocation. 
 (a) Except as otherwise provided in paragraphs (b) and (c) below, in any Plan Year that the Plan is Top-Heavy, Employer Contributions (other than Salary Deferral Contributions and Employer
Matching Contributions included in the ADP and ACP tests described in Sections 5.5 and 5.7) allocated to the Accounts of each Participant who is a Non-Key Employee, shall be not less than the lesser of (i) three percent (3%) of the Non-Key
Employee’s Section 415 Compensation, or (ii) in the case where the Employer has no defined benefit plan which designates this Plan to satisfy Code Section 401, the largest percentage of Contributions and forfeitures (if
applicable), as a percentage of the first Two Hundred Thousand Dollars ($200,000) (as adjusted for cost-of-living increases in accordance with Code Section 401(a)(17)(B)) of Section 415 Compensation, allocated on behalf of any Key Employee
for that Plan Year. The minimum allocation shall be determined without regard to any Social Security contribution. This minimum contribution shall be made even though, under other provisions of the Plan, the Participant would not otherwise be
entitled to receive an allocation or would have received a lesser allocation for the Plan Year because of (i) the Participant’s failure to complete one thousand (1,000) Hours of Service (or any equivalent provided in the Plan) or
(ii) Section 415 Compensation less than a stated amount. 
 (b) The provisions in paragraph (a) above shall not
apply to any Participant who was not employed by the Employer on the last day of the Plan Year. 
 (c) The provisions in
paragraph (a) above shall not apply to any Participant to the extent the Participant is covered under any other plan or plans of the Employer. 
 (d) The minimum allocation required (to the extent required to be nonforfeitable under Code Section 416(b)) may not be forfeited under Code Section 411(a)(3)(B) or (D). 

  
 69 









 (e) Employer Matching Contributions shall be taken into account for purposes of satisfying
the minimum contribution requirements of Code Section 416(c)(2) and the Plan. The preceding sentence shall apply with respect to Employer Matching Contributions under the Plan or if applicable, another plan of the Employer that provides the
minimum contribution requirement. Employer Matching Contributions that are used to satisfy the minimum contribution requirements shall be treated as Employer Matching Contributions for purposes of the actual contribution percentage test and other
requirements of Code Section 401(m). 

  
 70 









 ARTICLE XV. 
 MISCELLANEOUS 
 15.1 Legal or Equitable Action. If any
legal or equitable action with respect to the Plan is brought by or maintained against any individual, and the results of such action are adverse to that individual, attorney’s fees and all other direct and indirect expenses and costs incurred
by the Participating Employer, the Administrator, the Committee, or the Trust of defending or bringing such action shall be charged against the interest, if any, of such individual under the Plan. 

15.2 Indemnification. Each Participating Employer indemnifies and holds harmless any of its Employees, officers and
directors who may be fiduciaries of the Plan, and the Administrator and each member of the Committee, from and against any and all direct and indirect liabilities, demands, claims, losses, taxes, costs, and expenses, including reasonable
attorney’s fees, arising out of, relating to, or resulting from any action, inaction or conduct in their official capacity in the administration of this Plan or Trust, or in their defense if a Participating Employer fails to provide such
defense; provided, however, that the Administrator or the Member shall not be indemnified and held harmless if his or her action, inaction or conduct arises out of, related to, or results from his or her gross negligence or willful misconduct, or
otherwise is in willful violation of the law. The indemnification provisions of this Section shall not relieve any fiduciary from any liability such individual may have under ERISA for breach of a fiduciary duty. Each Participating Employer may
purchase insurance to satisfy its obligations under this Section 15.2. 
 15.3 No Enlargement of Plan Rights.
Each individual agrees, as a condition of participation in this Plan, that he or she shall look solely to the assets of the Trust for the payment of any benefit under the Plan. 

15.4 No Enlargement of Employment Rights. Nothing appearing in or done pursuant to the Plan shall be construed to give any
individual a legal or equitable right or interest in the assets of the Trust or distribution therefrom (except as expressly provided in the Plan), nor against any Participating Employer (except as expressly provided herein), or to create or modify
any contract of employment between a Participating Employer and any Employee or to obligate a Participating Employer to continue the services of any Employee. 
 15.5 Interpretation. The headings contained in this Plan or in an Appendix hereto, and in the table of contents to the Plan are for reference purposes only, and shall not affect in any
way the meaning or interpretation of the Plan. Any capitalized term used in any Appendix hereto, but not otherwise defined therein, shall have the meaning assigned to such term in the Plan. The masculine pronoun shall include the feminine
pronoun or the singular the plural, where the context so indicates. 

  
 71 









 15.6 Governing Law. This Plan shall be construed, administered and governed in
all respects in accordance with ERISA, the Code and other pertinent Federal laws and, to the extent not preempted by ERISA, in accordance with the laws of the State of California (irrespective of the choice of law principles of the State of
California as to all matters); provided, however, that if any provision is susceptible to more than one interpretation, such interpretation shall be given thereto as is consistent with the Plan being a tax-qualified plan and related tax-exempt trust
under Code Sections 401(a) and 501(a), respectively. 
 15.7 Non-Alienation of Benefits. None of the
benefits, payments, proceeds or claims of any Participant under the Plan shall be subject to any claim or any creditor of any Participant, and, in particular, the same shall not be subject to attachment or garnishment or other legal process by any
creditor of any Participant, nor shall any Participant have any right to alienate, anticipate, commute, pledge, encumber or assign any of the benefits, payments or proceeds which he or she is or may be entitled to receive from the Plan, other than:

 (a) federal tax levies and executions on federal tax judgments; 

(b) payments made from the Accounts of a Participant in satisfaction of the rights of Alternate Payees pursuant to a Qualified Domestic
Relations Order under Section 7.7; 
 (c) enforcement of any security interests or offset rights applicable to the Account
of a Participant pursuant to the loan provisions of Section 6.18; or 
 (d) any offset of a Participant’s Account
under the Plan against an amount the Participant is ordered to pay due to a judgment or settlement described in Code Section 401(a)(13)(C). 
 15.8 No Reversion. Notwithstanding any contrary provision of the Plan (except as provided in Section 5.4), no part of the assets in the Trust shall revert to the Employer, and no part
of such assets, other than that amount required to pay taxes or reasonable administrative expenses of the Plan, shall be used for any purpose other than exclusive benefit of Employees or their Beneficiaries. However, upon the Company’s request,
the Trustee shall return the appropriate amount to a Participating Employer under any of the following circumstances: 
 (a) the
amount was all or part of an Employer Contribution which was made as a result of a mistake of fact and the amount contributed is returned to the Participating Employer within one (1) year after the date of the mistaken payment; or 

(b) the amount was all or part of an Employer Contribution which was conditioned on its deductibility under Code Section 404 and
this condition is not 

  
 72 









 
satisfied, and the amount is returned to the Participating Employer within one (1) year after the date on which the deduction was disallowed; 

provided, however, any such excess amounts shall be reduced to the extent there are negative Earnings attributable thereto. 

15.9 Conflict. In the event of any conflict between the respective provisions of the Plan and the Trust Agreement relating
to the rights, obligations and duties of the Trustee, then the applicable provisions of the Trust Agreement shall control. In all other cases, in the event of any conflict between the Plan and the terms of any contract or agreement issued hereunder
or with respect hereto, the Plan shall control. 
 15.10 Severability. If any provision of the Plan, or the
application thereof to any individual or circumstance, is deemed invalid or unenforceable by a court of competent jurisdiction, then the remainder of the Plan, or the application of such term or provision to individuals or circumstances other than
those as to whom it is held invalid or unenforceable, shall not be affected thereby, and each provision of the Plan shall be valid and enforceable to the fullest extent permitted by law. 

15.11 Conditional Restatement. This Plan is restated on the express condition that it shall be considered by the Internal
Revenue Service as continuing to qualify under Code Sections 401(a), 401(k), 401(m) and 501(a). In the event that the Internal Revenue Service determines that the Plan does not continue to qualify under the Code, then the restatement of the Plan
shall be of no force or effect.

 APPENDIX A 
 GUIDELINES FOR ANNUITY FORMS OF DISTRIBUTION 
 The provisions of this
Appendix A are intended to set forth the guidelines for providing annuities as a form of distribution under the Plan. Annuities shall only be offered to certain Participants (or Surviving Spouses or Beneficiaries thereof, as applicable) to the
extent required to comply with Code Section 411(d)(6), as more specifically detailed in the subsequent Appendices. 
 A.1.
Definitions. 
 For purposes of applying the provisions of the subsequent Appendices (unless specified otherwise),
as applicable, the following definitions shall be in effect: 
 (a) Annuity Contract. “Annuity Contract” means
a paid-up, non-transferable annuity contract issued by an insurance company qualified to do business in the State of California. Any annuity benefits to which a Participant (or his or her Surviving Spouse or Beneficiary) is entitled under the Plan
shall be provided under an Annuity Contract purchased by the Administrator with the balance credited to the Participant’s Account at the time of such purchase. The amount of such benefit shall be determined in accordance with the annuity
purchase rates in effect at the time for the Annuity Contract. The purchase of the Annuity Contract shall be effected immediately prior to the date benefits are to commence under the Plan, and the purchased Annuity Contract shall be distributed to
the Participant as soon as administratively feasible. 
 (b) Annuity Starting Date. “Annuity Starting Date”
means the first day of the first period for which an amount is payable as an annuity or, in the case of a benefit not payable in the form of an annuity, the first day on which all the events have occurred which entitle the Participant (or his or her
Surviving Spouse or Beneficiary, as applicable) to such benefit. 
 (c) Qualified Joint and Survivor Annuity.
“Qualified Joint and Survivor Annuity” means an annuity for the life of the Participant with a survivor annuity for the remaining life of the Surviving Spouse (or, to the extent provided in a subsequent Appendix, the Beneficiary) equal to
a specified percentage of the annuity payable during the joint lives of the Participant and his or her Spouse (or to the extent provided in a subsequent Appendix, the Beneficiary). Such annuity shall be the actuarial equivalent of the balance
credited to the Participant’s Account at the time the Annuity Contract is purchased. 
 (d) Qualified Preretirement
Survivor Annuity. “Qualified Preretirement Survivor Annuity” means an annuity for the life of the Surviving Spouse of a Participant who dies before his or her Annuity Starting Date which is the actuarial equivalent of the balance
credited to the Participant’s Account at the time the Annuity Contract is purchased. 

  
 A-1









 (e) Required Beginning Date. “Required Beginning Date” shall have the
meaning assigned to such term in Section 6.12(a). 
 (f) Normal Retirement Age. “Normal Retirement Age”
shall mean the age specified in Section 2.28. 
 (g) Straight Life Annuity. “Straight Life Annuity” means
an annuity payable for the life of the Participant which is the actuarial equivalent of the balance credited to the Participant’s Account at the time the Annuity Contract is purchased. 

A.2. Qualified Joint and Survivor Annuity. 
 (a) Written Explanation. If the balance credited to the Participant’s Account at the time distribution is to commence exceeds Five Thousand Dollars ($5,000) (as prescribed in Sections
6.8(b) and (c)), then the Administrator shall furnish to the Participant and his or her Spouse a written explanation of the terms and conditions of the Qualified Joint and Survivor Annuity, including the circumstances under which it will be
provided. In addition, if the Qualified Joint and Survivor Annuity is the automatic form of distribution, then the written explanation shall also include: (i) the Participant’s right to make, and the effect of, an election to waive the
Qualified Joint and Survivor Annuity; (ii) the rights of the Spouse with respect to such election, including the Spouse’s right to limit his or her consent to a specific Beneficiary or a specific form of benefit; and (iii) the right
to revoke an election and the effect of such a revocation. The Administrator shall furnish the written explanation by a method reasonably calculated to reach the attention of the Participant no less than thirty (30) days and no more than one
hundred eighty (180) days before the Annuity Starting Date. 
 (b) Request for Additional Information. After the
written explanation of the Qualified Joint and Survivor Annuity is given, a Participant or his or her Spouse may make a written request for additional information. Upon receipt of the written request for additional information, the Administrator
shall provide a written explanation in nontechnical language which will explain the terms and conditions of the Qualified Joint and Survivor Annuity and the financial effect upon the Participant’s benefit (in terms of dollars per benefit
payment) of electing not to have benefits distributed in accordance with the Qualified Joint and Survivor Annuity. The written explanation must be personally delivered or mailed (first class mail, postage prepaid) to the Participant and his/her
Spouse within thirty (30) days after the date of the written request. The Administrator need not comply with more than one such request by a Participant or his or her Spouse. 

  
 A-2









 (c) Election to Waive Qualified Joint and Survivor Annuity. An election to waive the
Qualified Joint and Survivor Annuity shall only be required if such form of distribution is the automatic form, as specified in the subsequent Appendices. Accordingly, to the extent applicable, an election to waive the Qualified Joint and Survivor
Annuity may not be made by the Participant (and if the Participant is married on his or her Annuity Starting Date, the Participant’s Spouse (or, if either the Participant or the Spouse has died, the survivor)) before the date he or she is
provided with notice of the ability to waive the Qualified Joint and Survivor Annuity. A Participant’s (and, if applicable, his or her Spouse’s) election to waive the Qualified Joint and Survivor Annuity can be made during the one hundred
eighty (180)-day period ending on the Annuity Starting Date. Spousal consent shall be in the form and manner prescribed in Section A.4(c). 
 A.3. Qualified Preretirement Survivor Annuity. 
 (a) Written
Explanation. The Administrator shall furnish to the Participant a written explanation of the following: (i) the terms and conditions of the Qualified Preretirement Survivor Annuity, including the circumstances under which it will be
provided; (ii) the Participant’s right to make, and the effect of, an election to waive the Qualified Preretirement Survivor Annuity; (iii) the rights of the Spouse with respect to such election, including the Spouse’s right to
limit his or her consent only to a specific Beneficiary; and (iv) the right to make, and the effect of a revocation of an existing election. The Administrator shall furnish the written explanation by a method reasonably calculated to reach the
attention of the Participant within the applicable period. The applicable period for a Participant is whichever of the following periods ends last: 
 (i) the period beginning one (1) year before the date the individual becomes a Participant and ending one (1) year after such date; or 

(ii) the period beginning one (1) year before the date the Participant’s Spouse is first entitled to a Qualified Preretirement
Survivor Annuity and ending one (1) year after such date. 
 If such notice is given before the period beginning with the
first day of the Plan Year in which the Participant attains age thirty-two (32) and ending with the close of the Plan Year preceding the Plan Year in which the Participant attains age thirty-five (35), then an additional notice shall be given
within such period. If a Participant ceases to be an Employee before attaining age thirty-five (35), then an additional notice shall be given within the period beginning one (1) year before the date the Participant ceases to be an Employee and
ending one (1) year after such date. 
 (b) Request for Additional Information. After the written explanation of the
Qualified Preretirement Survivor Annuity is given, a Participant or his or her Spouse may make a written request for additional information. Upon receipt of a timely request for 

  
 A-3









 
additional information, the Administrator shall provide a written explanation in nontechnical language which will explain the terms and conditions of the Qualified Preretirement Survivor Annuity
and the financial effect upon the Spouse’s benefit (in terms of dollars per benefit payment) of electing not to have benefits distributed in accordance with the Qualified Preretirement Survivor Annuity. The written explanation must be
personally delivered or mailed (first class mail, postage prepaid) to the Participant or his or her Spouse within thirty (30) days from the date of the written request. The Administrator need not comply with more than one such request by a
Participant or his or her Spouse. 
 (c) Election to Waive Qualified Preretirement Survivor Annuity. An election to waive
the Qualified Preretirement Survivor Annuity may not be made by the Participant before the date he or she is provided with the notice of the ability to waive the Qualified Preretirement Survivor Annuity. A Participant’s election to waive the
Qualified Preretirement Survivor Annuity which is made before the first day of the Plan Year in which he or she reaches age thirty-five (35) shall become invalid on such date. However, an election made by a Participant after he or she ceases to
be an Employee will not become invalid on the first day of the Plan Year in which he or she reaches age thirty-five (35) with respect to death benefits payable from his or her Account. 

A.4. Election of Optional Forms of Benefit. 
 (a) Written Explanation. If the balance credited to the Participant’s Account at the time distribution is to commence is in excess of Five Thousand Dollars ($5,000) (as prescribed in Sections
6.8(b) and (c)), then the Administrator shall furnish to the Participant and his or her Spouse a written explanation of the optional forms of retirement benefit provided under the Plan, including (without limitation): (i) the material
features and relative values of each automatic and optional form, in a manner which complies with the notice requirements of Code Section 417(a)(3)), and (ii) the right of the Participant and his or her Spouse to defer distribution until
the benefit is no longer immediately distributable. 
 (b) Election. The Administrator shall furnish the written
explanation by a method reasonably calculated to reach the attention of the Participant no less than thirty (30) days and no more than one hundred eighty (180) days before the Annuity Starting Date. In addition, if the Qualified Joint and
Survivor Annuity is the automatic form of distribution and if the Participant should, after having received the written explanation of the Qualified Joint and Survivor Annuity, affirmatively elect a form of distribution other than the Qualified
Joint and Survivor Annuity or the Qualified Preretirement Survivor Annuity, then the election shall be valid only if the consent requirements of paragraph (c) below are met. 

  
 A-4









 (c) Consent. If the Qualified Joint and Survivor Annuity is the automatic form of
distribution, as specified in any of the subsequent Appendices, then the following consent provisions are applicable: 
 (i)
Requirement of Consent. Any benefit which is immediately distributable or payable in a form other than a Qualified Joint and Survivor Annuity or a Qualified Preretirement Survivor Annuity requires the written consent of the Participant and
his other Spouse prior to distribution. Spousal consent will not be required if the Participant establishes to the satisfaction of the Administrator that the consent of the Spouse cannot be obtained because there is no Spouse or the Spouse cannot be
located. Neither the consent of the Participant nor the Participant’s Spouse shall be required to the extent that a distribution is required to satisfy Code Section 401(a)(9) or 415. A benefit is immediately distributable if any part of
the benefit could be distributed to the Participant (or surviving Spouse) before the Participant attains (or would have attained if not deceased) Normal Retirement Age or, if later, age sixty-two (62). 

(ii) Form of Consent. The consent of the Participant and, if applicable his or her Spouse must be made in writing and witnessed by
a Plan representative or notary public. In the event the Spouse elects to waive the Qualified Joint and Survivor Annuity and/or Qualified Preretirement Survivor Annuity, then the Spouse shall have the right to limit such consent only to a specific
Beneficiary or a specific form of distribution. The Spouse can relinquish one or both of those rights. The Spouse’s consent must acknowledge the effect of the waiver, including: (A) the Spouse had the right to limit his or her consent only
to a specific Beneficiary or, if applicable, to a specific form of benefit; (B) the Spouse voluntarily relinquished one or both of those rights; and (C) the Spouse understands the effect such consent has upon the benefits which would

eighty (180) days prior to the date specified for distribution, the Participant (and, if applicable, his or her Spouse) shall be provided with written information relating to his or her right to defer such distribution in accordance with the
