adjusted at the same time and in the same manner as under Section 415(d), except that the base period is the calendar quarter ending September 30, 1996. An Employee is in the top-paid group of Employees for any year if such Employee is in
the group consisting of the top 20% of the Employees when ranked on the basis of Compensation paid during such year. For this purpose, the applicable year of the Plan for which a determination is being made is called a determination year and the
preceding 12-month period is called a look-back year. 
 The determination whether a former Employee is a “highly compensated former

to the extent that such back pay is agreed to or awarded for a period of time during which an Employee did not or would not have performed duties. In applying this Subsection (v), an Employee shall be credited with Hours of Employment Service,
beginning with the first day duties are not performed, until he receives a maximum of 501 Hours of Employment Service. 
 (vi) With respect
to any Authorized Leave of Absence which is not compensated by the Employer, an Employee shall be credited with his average number of Hours of Employment Service, determined under either of Subsections (i)(1) or (2), whichever applies, computed from
the 12-month period preceding his absence, or if less, during his entire period of employment. Credit for each Hour of Employment Service under this Subsection (vi) shall be given for the Computation Period during which the absence occurred,
except that, for purposes of whether an Employee has a Break-in-Service, such credit shall be given only after the Employee returns to the active employ of the Employer.

 (vii) With respect to other special rules applying to this Subsection, Sections 2530.200b-2(b) and
(c) of the Minimum Standard Regulations (December 28, 1976, Federal Register, Vol. 41, No. 250) issued by the Department of Labor are incorporated herein by reference and made a part hereof. 
 (viii) Notwithstanding the foregoing provisions of this Subsection, the Employer may compute Hours of Employment Service prior to the Effective Date

(4) caring for such child for a period beginning immediately following such birth or placement. The Hours of Employment Service credited under this Subsection shall be credited (1) in the Computation Period in which the absence begins if
the crediting is necessary to prevent a Break-in-Service in that period, or (2) in all other cases, in the following Computation Period. This Subsection shall apply in crediting Hours of Employment Service in determining whether or not a
Participant has incurred a Break-in-Service with respect to any relevant Computation Year, and, accordingly, shall not apply for any other purpose including, without limitation, benefit accrual service or eligibility service. For the purposes of
this Subsection (xi), the actual calculation of any such Hours of Employment Service will be as provided in Subsection (vi) hereof.

or “NHCE” shall mean an Employee of the Employer who is not a HCE. 
 (ee) Normal Retirement Date: The words “Normal
Retirement Date” shall mean the date on which a Participant attains the age of 65 years.

 II-9 

 (nn) Testing Compensation: The words “Testing Compensation” shall mean any definition of
compensation which satisfies Section 414(s) of the Code. Testing Compensation shall be based on the amount actually paid to a Participant during the testing year or, at the option of the Employer, during that portion of the testing year during
which the Participant is an active Participant; provided, however, that if the Employer elected different eligibility service requirements for purposes of making eligibility to make 401(k) Contributions and to receive Matching Contributions, then
Testing Compensation must be based on the amount paid to a Participant during the full testing year. The annual Testing Compensation of each Active Participant taken into account in applying the ADP Test and the ACP Test shall not exceed the annual
compensation limit under Section 401(a)(17) of the Code as in effect on the first day of the testing year as adjusted by the Secretary to reflect increases in the cost of living, as provided in Section 401(a)(17)(B) of the Code; provided,
however, that the dollar increase in effect on January 1 of any calendar year is effective for “testing years” beginning in such calendar year. If a Plan determines Testing Compensation over a period that contains fewer than 12
calendar months (a “short determination period”), then the Compensation limit for such short determination period is equal to the Compensation limit for the calendar year in which the “short determination Period” begins
multiplied by the ratio obtained by dividing the number of full months in the short determination period by 12; provided, however, that such proration shall not apply if there is a “short determination period” because (1) the Employer
elected in accordance with any rules and regulations issued by the Secretary of the Treasury or his delegate to apply the ADP Test and /or the ACP Test based only on amounts paid during the portion of the testing year during which an individual was
eligible to make such Contributions or (2) an employee is covered under the Plan for fewer than 12 calendar months.

Employer does reclassify such worker as an “Employee,” for purposes of this Plan, such reclassification shall only be prospective from the date that the Employee is notified by the Employer of such reclassification. 
 Section 3.2 Entry Date. An Employee, upon meeting the eligibility requirements of Section 3.1 herein, shall commence actual participation in the Plan as

 III-2 

 ARTICLE IV. 
 CONTRIBUTIONS - FORFEITURES - MAXIMUM ANNUAL ADDITIONS 
 Section 4.1 401(k) Contributions. 
 (a) Election to Make 401(k) Contributions. Contributions by Participants shall be permitted as provided herein. During each Election Period, a
Participant may, by any method acceptable to the Plan Administrator which may include voice, telephone or some other method, agree to defer a specified percentage of Compensation or a dollar amount, as permitted by the Plan Administrator, of such
Participant’s Compensation payable during the applicable Contribution Period as a 401(k) Contribution. Such salary reduction agreement shall become effective on the first day of the Contribution Period for which the Employer can reasonably
process the request and can only be made with respect to an amount that is not currently available to the Participant on the date of the election. Such election shall be effective on a prospective basis only and will remain in effect until modified
or terminated. 401(k) Contributions not otherwise designated as Roth 401(k) Contributions shall be made on a pre-tax basis as Pre-Tax 401(k) Contributions. 
 (b) Election to Make Catch-Up Contributions. For Plan Years beginning after December 31, 2001, Catch-Up Eligible Participants shall be eligible to make Catch-Up Contributions in accordance with, and
subject to the limitations of, Section 414(v) of the Code. Catch-Up Contributions are Employee Contributions made to the Plan that are in excess of an otherwise applicable Plan limit. An otherwise applicable Plan limit is a limit in the Plan
that applies to 401(k) Contributions, such as the limits on Annual Additions, the dollar limitation on 401(k) Contributions under Section 402(g) of the Code (not counting Catch-Up Contributions), the limit imposed by the ADP Test under
Section 401(k)(3) of the Code or any contribution limitation imposed by the Plan. Catch-Up Contributions for a Participant for a taxable year may not exceed the dollar limit in effect under Section 414(v)(2)(B)(i) of the Code for the
taxable year as adjusted by the Secretary of the Treasury for cost-of-living increases under Section 414(v)(2)(C) of the Code. Catch-Up Contributions not otherwise designated as Roth Catch-Up Contributions, if applicable, shall be made on a
pre-tax basis as Pre-Tax Catch-Up Contributions. 
 (c) Election to Make Roth Contributions. Roth Contributions shall not be permitted
under this Plan. If Roth Contributions are permitted under this Plan in accordance with Section 402A of the Code, a Participant may make an election to designate 401(k) Contributions and/or Catch-Up Contributions as Roth 401(k) Contributions or
Roth Catch-Up Contributions. A Participant’s Roth Contributions will be deposited in a separate Account in the Plan used to hold only Roth Contributions. No contributions other than Roth Contributions and properly attributable earnings will be
credited to each Participant’s Account holding Roth Contributions and Roth Catch-Up Contributions, and gains, losses and other credits or charges will be allocated on a reasonable and consistent basis to such Account. The Plan will maintain a
record of the amount of Roth Contributions in each such Account. 
 (d) Participants on Authorized Leave of Absence. Participants who
are on an Authorized Leave of Absence and who actually receive Compensation while on such, including, without limitation, sick pay, shall be entitled to continue Elective Deferrals. Participants on a leave of absence in the uniformed services shall
be entitled to make Elective Deferrals to the Plan in accordance with the provisions of USERRA. 
  

 IV-1 

 (e) Discontinuance, Change of Percentage of Deferrals of Compensation or Withdrawal. In accordance
with procedures established by the Plan Administrator, a Participant may elect to change his elected percentage and/or type of Elective Deferrals, or he may elect to discontinue his Elective Deferrals by communicating such election to the Plan
Administrator in such manner as required by the Plan Administrator. Elections shall become effective as of the January 1 or July 1 following communication to the Plan Administrator or its designee, provided, a Participant may discontinue
making 401(k) Contributions at any time and such election will be effective as soon as administratively feasible. A Participant who has received a distribution on account of a hardship as described in Article VI shall be suspended from making
further Elective Deferrals during the six (6) calendar month period following the date of such hardship distribution. 
 (f) Deposits
of 401(k) Contributions. All Elective Deferrals made hereunder for a Participant shall be paid to the Trustees no later than the 15th business day of the month following the month in which such amounts would otherwise have been payable in cash
to Participants. 
 (g) Payroll Deduction. Elective Deferrals shall be made from amounts of Compensation which otherwise would be paid
under the Employer’s regular payroll system. Accordingly, Elective Deferrals shall be made by payroll deduction. Any Contribution pursuant to this Section will be subject to amounts required to be withheld by applicable law or other agreement.

 (h) Limit on Elective Deferrals to Satisfy the ADP Test and/or ACP Test. In the event that the Plan Administrator, at its sole
discretion, estimates that the Elective Deferrals which will be made to the Plan with respect to a Plan Year will not satisfy the ADP Test or the ACP Test, the Plan Administrator may reduce or adjust, at any time or times before the close of the
Plan Year, the maximum percentage of Compensation that all HCEs shall be permitted to elect to contribute as Elective Deferrals for the remainder of the Plan Year to meet one of the tests set forth above. 
 Section 4.2 Dollar Limitation on 401(k) Contributions. 
 (a) General Rule. No Participant shall be permitted to make Elective Deferrals during any calendar year in excess of the dollar limitation contained in Section 402(g) of the Code (including, if applicable, the dollar limitation
on Catch-Up Contributions defined in Section 414(v) of the Code) in effect as of the beginning of the taxable year as adjusted under Section 402(g)(4) of the Code (hereafter referred to as “Excess Elective Deferrals”). In the
case of a Participant who is age 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. In the event a Catch-Up Eligible
Participant makes Excess Elective Deferrals, the Plan Administrator shall cause such Participant’s 401(k) Contributions to be recharacterized as Catch-Up Contributions to the extent necessary to either (i) exhaust his Excess Elective
Deferrals, and/or (ii) increase his Catch-Up Contributions to the applicable limit under Section 414(v) of the Code for the Plan Year. 
  

 IV-2 

 (b) Recharacterization to Meet Limits of Section 402(g) of the Code. In the event a
Participant’s 401(k) Contributions for a Plan Year do not equal the maximum Contributions that may be made under the Plan during that Plan Year for any reason, the Participant’s Catch-Up Contributions for such Plan Year shall be
recharacterized as 401(k) Contributions for all purposes to the extent necessary to increase his 401(k) Contributions to equal such maximum for such Plan Year. If such recharacterized contributions were originally made as Roth Contributions, then
such Contributions shall retain their Roth status after recharacterization. 
 (c) Corrective Distributions. 
 (i) General. Notwithstanding any other provision of the Plan to the contrary, Excess Elective Deferrals (remaining after recharacterization as
discussed above) and income and loss allocable thereto for the applicable calendar year must be distributed no later than April 15 following the calendar year in which Excess Elective Deferrals are incurred to avoid penalty, to Participants who
have Excess Elective Deferrals for the preceding calendar year, unless a timely claim is delivered as provided in Subsection (ii) hereafter. For years beginning after 2005, distribution of Excess Elective Deferrals for a year shall be made
first from the Participant’s Account holding Pre-tax 401(k) Contributions, to the extent Pre-tax 401(k) Contributions were made for the year, unless the Participant specifies otherwise. 
 (ii) Claims. The Participant’s claim shall be in writing, shall be submitted to the Plan Administrator no later than March 1; shall
specify the Participant’s Excess Elective Deferrals for the preceding calendar year; and shall be accompanied by the Participant’s written statement that if such amounts are not distributed, such Excess Elective Deferrals, when added to
amounts deferred under other plans or arrangements described in Sections 401(k), 408(k) or 403(b) of the Code, exceeds the limit imposed on the Participant by Section 402(g) of the Code for the year in which the deferral occurred. A Participant
is deemed to notify the Plan Administrator of any Excess Elective Deferrals if such Excess Elective Deferrals arise solely from this Plan and any other plan, contract or arrangement of the Employer. 
 (iii) Calculation of Income Allocable to Excess Elective Deferrals. The Plan Administrator may use any reasonable method for computing the income
allocable to corrective distributions, provided that the method does not violate Section 401(a)(4) of the Code, is used consistently for all Participants, and for all corrective distributions under the Plan for the Plan Year, and is used by the
Plan for allocating income to all Participants’ Accounts. A Plan will not fail to use a reasonable method for computing the income allocable to Excess Contributions merely because the income allocable to Excess Contributions is determined on a
date that is no more than seven (7) days before the distribution. The Plan Administrator may use any of the rules for determining income allocable to corrective distributions contained in Regulation § 1.401(k)-1(f)(4). For Plan Years
beginning after December 31, 2005 and before January 1, 2007, income or loss allocable to the period between the end of the taxable year and the date of distribution (“gap period”) must be taken into account for corrective
distributions. 
  

 IV-3 

 Section 4.3 Safe Harbor Contributions. The provisions of this Section shall not apply until enacted by the
Company for any Plan Year. If this Section is applicable then any provisions relating to the ADP Test described in Section 401(k)(3) of the Code or the ACP Test described in Section 401(m)(2) of the Code and as set forth in this Article do
not apply. To the extent that any other provision of the Plan is inconsistent with the provisions of this Section, the provisions of this Section govern. 
 (a) Safe Harbor Non-elective Contributions. If this Section applies, the Employer will make a Safe Harbor Non-elective Contribution to the Account of each Eligible Employee in an amount equal to 3% of the
Employee’s Compensation for the Plan Year. Such contributions must be allocated without regard to permitted disparity under Section 401(l) of the Code. 
 (b) Eligible Employee. For purposes of this Section, the words “Eligible Employee” mean an Employee eligible to make 401(k) Contributions under the Plan for any part of the Plan Year or who would be
eligible to make 401(k) Contributions but for a suspension due to a hardship distribution described in Article VI of the Plan or to statutory limitations, such as Sections 402(g) and 415 of the Code. 
 (c) Distribution Restrictions. The Participant’s accrued Benefit derived from Safe
Harbor Contributions is non-forfeitable and may not be distributed earlier than the Participant’s severance from employment, death, disability, an event described in Section 401(k)(10) of the Code, or the attainment of age 59 1/2. 
 (d)
Notice Requirement. At least 30 days, but not more than 90 days, before the beginning of the Plan Year, the Employer will provide each Eligible Employee a comprehensive notice of the employee’s rights and obligations under the Plan,
written in a manner calculated to be understood by the average Eligible Employee. If an Employee becomes eligible after the 90th day before the beginning of the Plan Year and does not receive the notice for that reason, the notice must be provided
no more than 90 days before the Employee becomes eligible but not later than the date the Employee becomes eligible. 
 Section 4.4 Average Deferral
Percentage Test. 
 (a) ADP Test. The Plan, with respect to a Plan Year, must satisfy the actual deferral percentage test
(“ADP Test”) set forth in Section 401(k)(3) of the Code and Treasury Regulation 1.401(k)-2 as modified by (b) below. The ACP for Participants who are HCEs for the Plan Year shall not exceed the greater of: 
 (i) the ADP for Participants who are NHCEs for the current Plan Year multiplied by 1.25, or 
 (ii) the lesser of (i) the ADP for Participants who are NHCEs for the current Plan Year multiplied by 2 and (ii) the ADP for Participants who
are NHCEs for the current Plan Year plus 2%. 
  

 IV-4 

 (b) Special Rules. In performing the ADP Test, the following special rules will apply: 

(i) The deferral percentages of Participants who are covered by a collective bargaining agreement between employee representatives and an Employer
will be disaggregated from the deferral percentages of other Participants and the provisions of this Section will be applied separately with respect to each group. 
 (ii) For the first Plan Year if the Plan permits any Participant to make Elective Deferrals and this is not a successor plan, for purposes of the ADP Test, the prior year’s NHCEs’ ADP shall be 3% unless the
Employer has elected to use the current Plan Year’s ADP for these Participants. 
 (iii) The Plan Administrator may permissively
aggregate the Plan with other plans to the extent permitted under Treasury Regulation §1.401(k)-1. 
 (iv) The Plan Administrator may
permissively disaggregate the deferral percentages of Participants under the age of 21 or with less than one Year of Service and apply the provisions of this Section separately with respect to such Participants and the remaining Participants as
permitted under Section 401(k)(3)(F) of the Code and applicable Treasury Regulations. 
 (v) For purposes of this Section, the ADP for
any Participant who is an HCE for the Plan Year and who is eligible to make 401(k) Contributions or Special Section 401(k) Contributions under two or more plans or arrangements (“CODAs”) that are maintained by the Employer or an
Affiliated Employer shall be determined as if all such 401(k) Contributions and Special Section 401(k) Contributions were made under each plan or arrangement. If an HCE participates in two or more such plans or arrangements that have different
Plan Years, all ADP Test Contributions made during the Plan Year under all such plans shall be aggregated. For Plan Years beginning before 2006, all such CODAs ending with or within the same calendar year shall be treated as a single arrangement.
Notwithstanding the foregoing, certain plans shall be treated as separate if mandatorily disaggregated under regulations under Section 401(k) of the Code. 
 (vi) In the event that this Plan satisfies the requirements of Section 401(k), 401(a)(4), or 410(b) of the Code 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. 
 (vii) Plans may be aggregated in order to satisfy Section 401(k) of the Code only if they have the same Plan Year and use the same ADP testing
method. 
 (viii) The Plan Administrator may take Special Section 401(k) Contributions into account for purposes of calculating a
Participant’s ADP. In determining testing deferrals for purposes of the ADP Test, the Plan Administrator shall include the amount of Special Section 401(k) Contributions that are necessary to meet the ADP Test. Provided, however, any
Special Section 401(k) Contribution that is taken into account under the ACP Test 

  

 IV-5 

 
is not permitted to be taken into account for purposes of the ADP Test and any Special Section 401(k) Contribution that is taken into account under the
ADP Test is not permitted to be taken into account under the ACP Test. 
 (c) Methods to Correct Violations of ADP Test. 

(i) Correction Method. In the event the ADP Test for a Plan Year is not satisfied, (1) the Employer may make Special Section 401(k)
Contributions allocated to Participants who are NHCEs included in such tests beginning with the lowest paid Participant in an amount equal to the lesser of (a) the maximum amount contributable under the Plan or (b) the amount necessary to
satisfy the ADP Test, and then to the next lowest paid Participant with the contribution repeating until the Special Section 401(k) Contributions are fully allocated, (2) the Plan Administrator may distribute the Excess Elective
Contributions of HCEs as discussed below, or (3) a combination of the foregoing remedies may be applied in order that one of the foregoing tests is met for such Plan Year in accordance with the requirements of Section 401(k) of the Code
and regulations promulgated thereunder. For Plan Years beginning after December 31, 2005, the Employer will not make Special Section 401(k) Contributions for a Plan Year in an amount that will exceed the product of (1) a NHCEs testing
compensation and (2) the greater of (i) five percent (5%) or (ii) two times the Plan’s “representative contribution rate” as defined in Section 1.401(k)-2(a)(b)(iv)(B). 
 (ii) Distribution or Recharacterization of Excess Contributions. To satisfy the ADP Test,
the Plan Administrator may (1) cause Excess Contributions to be recharacterized as Pre-tax Catch-Up Contributions (if eligible) to the maximum extent possible and (2) distributed to the extent of any Excess Contributions remaining after
such recharacterization. An HCE may designate the extent to which the excess amount is composed of Pre-Tax Contributions and Roth Contributions, if applicable, but only to the extent such types if deferrals were made for the year. If an HCE does not
so designate, the Plan will distribute Roth Contributions, if applicable, first. Such distributions shall be distributed to such HCEs on the basis of the contribution amounts by, or on behalf of, each such person taken into account in determining
such person’s ADP. To avoid penalty, Excess Contributions and income allocable thereto for the applicable Plan Year must be distributed no later than 2 1/2 months after the end of the Plan Year to avoid the 10% excise tax but in no event no later than 12 months after a Plan Year. Furthermore, any Matching Contribution corresponding to the Excess Contribution that is
distributed shall be forfeited. 
 (iii) Calculation of Income Allocable to Excess Contributions. The Plan Administrator may
use any reasonable method for computing the income allocable to corrective distributions, provided that the method does not violate Section 401(a)(4) of the Code, is used consistently for all Participants, and for all corrective distributions
under the Plan for the Plan Year, and is used by the Plan for allocating income to all Participants’ Accounts. A Plan will not fail to use a reasonable method for computing the income allocable to Excess Contributions merely because the income
allocable to Excess Contributions is determined on a date that is no more than seven (7) days before the distribution. The Plan Administrator may use any of the rules for determining income allocable to Excess Contributions contained in
Regulation § 1.401(k)-1(f)(4). For Plan Years beginning after December 31, 2005 and before January 1, 2007, income or loss allocable to the period between the end of the taxable year and the date of distribution (“gap
period”) must be taken into account for corrective distributions. 
  

 IV-6 

 (d) Definitions. The following definitions shall apply for purposes of this Section: 

(i) Actual Deferral Percentage or ADP. The words “Actual Deferral Percentage” or “ADP” shall mean, for a specified group of
Participants for a Plan Year, the average of the ratios calculated separately for each Participant in such group of (1) the amount of Testing Deferrals for such Participant for the Plan Year to (2) the Testing Compensation of such
Participant for such Plan Year. 
 (ii) Excess Contributions. The words “Excess Contributions” shall mean, with respect to
any Plan Year, the excess of (1) the aggregate amount of Testing Deferrals used in computing the ADP of HCEs 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 HCEs in the order of their ADPs, beginning with the highest of such percentages). 
 (iii)
Qualified Non-Elective Contributions or QNECs. The words “Qualified Non-Elective Contributions” or “QNECs” shall mean Employer Special Section 401(k) Contributions. 
 (iv) Testing Deferrals. The words “Testing Deferrals” shall mean 401(k) Contributions (including Excess Elective Deferrals of HCEs),
Special Section 401(k) Contributions, any Contributions that qualify as qualified non-elective contributions and qualified matching contributions under the Treasury Regulations, but excluding 401(k) Contributions and Special Section 401(k)
Contributions that are taken into account in the ACP Test (provided that the ADP Test is satisfied both with and without exclusion of these Contributions. 
 Section 4.5 Special Section 401(k) Contributions. The Employer may make additional Contributions, within its discretion, to the Plan for the benefit of Participants who are NHCEs as necessary to pass the ADP Test or the ACP
Test. Additional Contributions shall be subject to all the provisions governing a Participant’s 401(k) Contribution Account, including, without limitation, the requirement that such contributions shall be 100% vested and nonforfeitable by the
Participant. Special Section 401(k) Contributions are subject to the same distribution restrictions as 401(k) Contributions. Any allocation formula must satisfy additional requirements specified in Regulation § 1.401(k)-2(a)(6) and
§ 1.401(m)-2(a)(6). 
 Section 4.6 Profit Sharing Contributions. An Employer may make discretionary Profit Sharing Contributions.
Profit Sharing Contributions for each Plan Year (reduced by Forfeitures) shall be allocated and credited to the applicable corresponding Profit Sharing Contribution Accounts of all Participants who earn 1,000 Hours of Employment Service for such
Plan Year; provided, for Plan Years beginning prior to the Effective Date, the rules of the Predecessor Plan shall apply with respect to eligibility to receive an allocation as aforesaid. Profit Sharing Contributions shall be allocated and credited
in the proportion that each such Participant’s Compensation for such Plan Year bears to the total Compensation for such Plan Year for all such Participants. 
  

 IV-7 

 Section 4.7 Matching Contributions. With respect to each Plan Year, the Employer may make , but is not
required to make, a Matching Contribution for any Plan Year equal to 50% of the Participant’s 401(k) Contributions for such Plan Year. For purposes of calculating Matching Contributions, a Participant’s 401(k) Contributions in excess of
six percent (6%) of the Participant’s Compensation for such Plan Year shall be disregarded. Matching Contributions shall be made only with respect to those Participants who are employed on the last day of the Plan Year; provided, a
Participant will not be required to satisfy such service requirement if such Participant’s employment is terminated due to death, disability or retirement on his Early Retirement Date or Normal Retirement Date. 
 Section 4.8 After Tax Contributions. This Section shall not apply to the Plan. 
 (a) Amount of Contributions. If applicable, each Participant may elect at the time he qualifies as a Participant or anytime thereafter to contribute to the Trust an amount which is at least 1%, but no more than
10%, of such Participant’s aggregate Compensation for all Plan Years of participation; provided, that voluntary After Tax Contributions for a particular Participant to all plans qualified under Section 401(a) of the Code shall never exceed
in the aggregate 10% of such Participants’ aggregate compensation for all years of participation in such qualified plans. Such election shall be effective on the first day of the Contribution Period next following the date on which such
election shall have been delivered to the Plan Administrator. After making such election, a Participant may further elect to reduce or increase (subject to the foregoing 1% and 10% limitations) or entirely suspend his contributions to the Trust.
Such election of reduction, increase or suspension of contributions, as the case may be, shall not be effective until the first day of the calendar month next following 30 days after the date notice of such election shall have been delivered to the
Plan Administrator. In the event of a suspension of all contributions, such Participant shall be prohibited from making further contributions hereunder until the first day of the Contribution Period next following the date notice of such election
shall have been delivered to the Plan Administrator. Any election hereunder shall be pursuant to form approved by the Plan Administrator who shall promptly furnish the appropriate form on request. (See Section 6.11 herein for the provisions
pertaining to withdrawals from an After Tax Contribution Account.) 
 (b) Employee Contributions Nondeductible. No contributions to an
After Tax Contribution Account made by a Participant shall be considered as “deductible voluntary employee contributions” as provided in Section 219 of the Code as amended by the Economic Recovery Tax Act of 1981. 
 Section 4.9 ACP Test on Matching Contributions and After Tax Contributions. 
 (a) ACP Test. The Plan will satisfy the actual contribution percentage test (“ACP Test”) set forth in Section 401(m)(2) of the Code and Treasury Regulation §1.401(m)-1(b), as modified by
Subsection (b) below. The Average Contribution Percentage (ACP) for Participants who are HCEs for the Plan Year shall not exceed the greater of: 
 (i) The ACP for Participants who are NHCEs for the current Plan Year multiplied by 1.25; or 
  

 IV-8 

 (ii) The lesser of (i) the ACP for Participants who are NHCEs for the current Plan Year multiplied
by two, and (ii) the ACP for Participants who are NHCEs plus two percentage points. 
 (b) Special Rules. In performing the ACP
Test described in Subsection (a), above, the following special rules will apply: 
 (i) The deferral percentages of Participants who are
covered by a collective bargaining agreement between employee representatives and an Employer will be disaggregated from the deferral percentages of other Participants and the provisions of this Section will be applied separately with respect
to each group. 
 (ii) For the first Plan Year, if this Plan permits any Participant to make After Tax Contributions, provides for Matching
Contributions or both, and this is not a successor plan, for purposes of the ACP Test, the prior year’s NHCEs’ ACP shall be 3% unless the current year testing method has been selected. 
 (iii) The Plan Administrator may permissively aggregate the Plan with other plans to the extent permitted under Treasury Regulation §1.401(m)-1.

 (iv) The Plan Administrator may permissively disaggregate the deferral percentages of Participants under the age of 21 or with less than
one Year of Service and apply the provisions of this section separately with respect to such Participants and the remaining Participants as permitted under Section 401(m)(5)(C) of the Code and applicable Treasury Regulations. 
 (v) For purposes of this Section, the ACP for any Eligible Participant who is a HCE for the Plan Year and who is eligible to make or receive ACP Test
Contributions (or amounts equivalent thereto under any other plan) allocated to his account under two or more plans described in Section 401(a) of the Code or arrangements described in Section 401(k) of the Code that are maintained by the
Employer or an Affiliated Employer shall be determined as if all such contributions were made under each plan or arrangement. If an HCE participates in two or more such plans or arrangements that have different Plan Years, all ACP Test Contributions
made during the Plan Year under all such Plans shall be aggregated. For Plan Years beginning before 2006, all such plans and arrangements ending with or within the same calendar year shall be treated as a single plan or arrangement. Notwithstanding
the foregoing, certain plans shall be treated as separate if mandatorily disaggregated under regulations under Section 401(m) of the Code. 
 (vi) In the event that this Plan satisfies the requirements of Section 401(k), 401(a)(4), or 410(b) of the Code 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. 
  

 IV-9 

 (vii) 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. 
 (viii) The Plan Administrator may take Special Section 401(k) Contributions into
account for purposes of calculating a Participant’s ADP. In determining testing deferrals for purposes of the ADP Test, the Plan Administrator shall include the amount of Special Section 401(k) Contributions that are necessary to meet the
ADP Test. Provided, however, any Special Section 401(k) Contribution that is taken into account under the ACP Test is not permitted to be taken into account for purposes of the ADP Test and any Special Section 401(k) Contribution that is
taken into account under the ADP Test is not permitted to be taken into account under the ACP Test. 
 (c) Distribution of Excess
Aggregate Contributions to Correct Violations of ACP Limitation. 
 (i)
General. Notwithstanding any other provision of the Plan, to avoid penalty, Excess Aggregate Contributions and income allocable thereto shall be forfeited, if forfeitable, or if not forfeitable, must be distributed no later than 12 months
after the end of the Plan Year (2 1/2 months to avoid the 10% excise tax) to Participants on whose behalf such Excess Aggregate
Contributions were made for the preceding Plan Year. After-Tax Contributions shall be distributed first, and then, to the extent necessary, Matching Contributions shall be distributed. Excess Aggregate Contributions are allocated to the HCEs with
the largest amounts of ACP Test Contributions taken into account in calculating the ACP test for the year in which the excess arose, beginning with the HCE with the largest amount of such ACP Test Contributions and continuing in descending order
until all the Excess Aggregate Contributions have been allocated. 
 (ii) Calculation of Income Allocable to Excess Aggregate
Contributions. The Plan Administrator may use any reasonable method for computing the income allocable to corrective distributions, provided that the method does not violate Section 401(a)(4) of the Code, is used consistently for all
Participants, and for all corrective distributions under the Plan for the Plan Year, and is used by the Plan for allocating income to all Participants’ Accounts. A Plan will not fail to use a reasonable method for computing the income allocable
to Excess Contributions merely because the income allocable to Excess Contributions is determined on a date that is no more than seven (7) days before the distribution. The Plan Administrator may use any of the rules for determining income
allocable to Excess Contributions contained in Regulation § 1.401(k)-1(f)(4). For Plan Years beginning after December 31, 2005 and before January 1, 2007, income or loss allocable to the period between the end of the taxable year
and the date of distribution (“gap period”) must be taken into account for corrective distributions. 
 (iii) Allocation of
Forfeitures. Amounts forfeited by HCEs under this Subsection and the ADP Test shall be treated as Annual Additions under this Plan and allocated in accordance with this Article, after all other Forfeitures have been allocated. Notwithstanding
the foregoing, no Forfeitures arising under this Subsection shall be allocated to the Account of any HCE. 
  

 IV-10 

 (d) Definitions. The following definitions shall apply for purposes of this Section: 

(i) Actual Contribution Percentage (ACP). The words “Actual Contribution Percentage” or “ACP” shall mean for a specified
group of participants for a Plan Year, the average of the ratios calculated separately for each Participant in such group of (1) the amount of ACP Test Contributions for such Participant for the Plan Year to (2) the Testing Compensation of
such Participant for such Plan Year. 
 (ii) ACP Test Contributions. The words “ACP Test Contributions” shall mean the sum
of Matching Contributions, After Tax Contributions (if applicable), and Special Section 401(k) 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 ACP Test Contributions 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 also may elect to use Elective Deferrals in the ACP Test Contributions 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. 
 (iii) Excess Aggregate Contributions. The words “Excess
Aggregate Contributions” shall mean, with respect to any Plan Year, the excess of (1) the ACP Test Contributions taken into account in computing the numerator of the ACP for HCEs for such Plan Year, over (2) the maximum ACP Test
Contributions permitted by the ACP Test (determined by hypothetically reducing contributions make on behalf of HCEs in order of their ACP beginning with the highest of such percentages. 
 (iv) Actual Contribution Percentage (ACP). The words “Actual Contribution Percentage” or “ACP” shall mean, for a specified
group of Participants for a Plan Year, the average of the ratios calculated separately for each Participant in such group of (1) the amount of ACP testing contributions for such Participant for the Plan Year to (2) the Testing Compensation
of such Participant for such Plan Year. 
 Section 4.10 Top-Heavy Plan. 
 (a) Employer Minimum Contribution. Notwithstanding anything herein to the contrary, if this Plan shall be a Top-Heavy Plan for a particular Plan
Year, then the sum of the Employer contributions and Forfeitures allocated to the Account of any Non-Key Employee who is a Participant in the Plan must equal a Contribution (“Employer Minimum Contribution”) equal to at least 3% of such
Participant’s Compensation. However, a lower Employer Minimum Contribution is permissible where the largest Employer contribution made or required to be made for Key Employees is less than 3% of Compensation and the Employer has no defined
benefit plan which designates the Plan to satisfy Section 401(a) of the Code. The contribution made or required to be made on behalf of any Key Employee is equal to the ratio of the sum of the contributions made or required to be made and
Forfeitures allocated for such Key Employee divided by the Compensation for such Key Employee. In determining the amount of any contributions made for any Key Employee, amounts treated as “deferrals of compensation” 

  

 IV-11 

 
pursuant to Section 401(k) of the Code will be considered as a contribution made by the Employer. Thus, the Employer Minimum Contribution that must be
provided for any Non-Key Employee for any Plan Year in which the Plan is a Top-Heavy Plan is the largest percentage of Compensation provided on behalf of any Key Employee for that Plan Year (if the largest percentage of Compensation provided on
behalf of any Key Employee for that Plan Year is less than 3%). This Employer Minimum Contribution shall be made even though, under other Plan provisions, the Participant would have received a lesser allocation of the Plan Year because of
(i) the Participant’s failure to complete 1,000 Hours of Employment Service (or any equivalent provided in the Plan), or (ii) the Participant’s failure to make mandatory employee Contributions, if required, including any
contributions made as “deferrals of compensation” pursuant to Section 401(k) of the Code. Such Employer Minimum Contribution provisions shall not apply to any Participant to the extent the Participant is covered under any other plan
or plans of the Employer and the Employer has provided that the minimum allocation or benefit requirement applicable to top-heavy plans will be met in the other plan or plans, or the Participant is not employed on the Anniversary Date of the
applicable Plan Year. Any Employer Minimum Contribution on behalf of a Participant shall not be subject to integration with Social Security Act. 
 (b) Application of Top-Heavy Provisions. The top-heavy provisions of this Section shall be applied as follows: 
 (i)
Single Plan Determination. Unless this Plan is included in an Aggregation Group, it will be considered top-heavy and the provisions of this Section shall be applicable, if, as of a Determination Date, the cumulative aggregation of the
accounts (within the meaning of Section 416(g) of the Code and regulations and rulings thereunder) of Key Employees under the Plan exceeds 60% of the cumulative accounts of all employees under the Plan as determined in accordance with
Section 416(g) of the Code and regulations and rulings thereunder. 
 (ii) Aggregation Group Determination. If the Plan is
included in an Aggregation Group, it will be considered top heavy and the provisions of this Section shall be applicable, if, as of a Determination Date, the sum of accounts (within the meaning of Section 416(g) of the Code and regulations and
rulings thereunder) of Key Employees under all defined contribution plans in the group and the cumulative accrued benefits (within the meaning of Section 416(g) of the Code and regulations and rulings thereunder) of Key Employees under all
defined benefit plans in such group exceed 60% of the same amounts determined for all employees under all plans included in the Aggregation Group. 
 (c) Top-Heavy Test. This subsection shall apply for purposes of determining the present values of the amounts of Account balances of Employees as of the determination date. 
 (i) Distributions During Year Ending on the Determination Date. The present values of 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 Section 416(g)(2) of the Code 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 

  

 IV-12 

 
under Section 416(g)(2)(A)(i) of the Code. In the case of a distribution made for a reason other than severance from employment, death, or disability,
this provision shall be applied by substituting 5-year period for 1-year period. 
 (ii) Employees Not Performing Services During Year
Ending on the Determination Date. The accounts of any individual who has not performed services for the Employer and its Affiliates during the 1-year period ending on the determination date shall not be taken into account. 
 (d) Definitions. For the purposes of this Section the following definitions shall be applicable: 
 (i) Aggregation Group: The words “Aggregation Group” shall mean a Permissive Aggregation Group or a Required Aggregation Group, as
applicable. 
 (ii) Permissive Aggregation Group: The words “Permissive Aggregation Group” shall mean 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 Sections 401(a)(4) and 410 of the Code. 
 (iii) Required Aggregation Group: The words “Required Aggregation Group” shall mean (1) each qualified plan of the Employer in
which at least one Key Employee participates or participated at any time during the Plan Year containing the determination date or any of the four preceding Plan Years (regardless of whether the Plan was terminated), and (2) any other qualified
plan of the Employer which enables a plan described in (1) to meet the requirements of Sections 401(a)(4) or 410 of the Code. 
 (iv)
Determination Date: The words “Determination Date” shall mean, with respect to any Plan Year subsequent to the first Plan Year, the last day of the preceding Plan Year, and for the first Plan Year of the Plan, the last day of that
Plan Year. 
 (v) Key Employee: The words “Key Employee” shall mean any Employee described in Section 416(i) of the
Code and the Treasury Regulations thereunder. 
 (vi) Non Key Employee: The words “Non Key Employee” shall mean any
Employee who is not a Key Employee. 
 (vii) Top-Heavy Compensation: The words “Top-Heavy Compensation” shall mean for all
purposes under this Section, annual compensation within the meaning of Code Section 415(c)(3) for the Plan Year containing the Determination Date. 
 (e) Top-Heavy Determination. The Plan Administrator shall determine whether the Plan is a Top-Heavy Plan with respect to each Plan Year and such determination shall be final and binding on all
Participants. 
 Section 4.11 Allocation of Forfeitures. Subject to the provisions related to the reinstatement of Forfeitures in Article VI, the
sum of all forfeited amounts by Participants becoming allocable during a Plan Year which are attributable to Employer Contributions shall be applied first to pay 

  

 IV-13 

 
or offset administrative expenses of the Plan for the year and next to reduce the Matching Contributions or Profit Sharing Contributions. Forfeitures arising
under Subsection 6.2(b) herein shall be allocated on the Anniversary Date within the Plan Year in which occurs the earlier of (i) the Participant’s receipt of a cash out of his entire vested Benefit, (ii) the Participant’s
termination of his employment with the Employer, and he has no vested rights in a Benefit which event shall be deemed to be a payment to the Participant and a cash out of his Benefit for all purposes, or (iii) the Participant’s incurrence
of five consecutive one-year Breaks-in-Service; provided, Forfeitures shall not be allocated on the Anniversary Date within the Plan Year in which (i) above applies if the Participant is reemployed with the Employer and repays all of such cash
out within the same said Plan Year; provided further, Forfeitures shall not be allocated on the Anniversary Date within the Plan Year in which (ii) above applies if the Participant is reemployed by the Employer within the same said Plan Year.
Forfeitures arising hereunder will be allocated only for the benefit of Participants of the Employer which adopted this Plan; provided further, effective for Plan Years commencing after 1989, all Affiliated Employers shall be aggregated and
hypothetically treated as if they were one single Employer and as if all Participants were employed by such hypothetical single Employer, and Forfeitures shall be uniformly allocated in accordance with the foregoing formula as if there were one
Employer. 
 Section 4.12 Limitation on Allocation of Employer Contributions. The provisions of this Section shall be effective for Plan Years
beginning after December 31, 2001. The following provisions will be applicable in determining if the Plan and the Employer Contributions thereto satisfy the requirements of Section 415 of the Code and the regulations thereunder.

 (a) Definitions. For the purposes of this Section the following definitions shall be applicable: 
 (i) Annual Additions: For purposes of the Plan, “Annual Additions” shall mean the amount allocated to a Participant’s Account
during the Limitation Year that constitutes: 
 (1) Contributions by the Employer, 
 (2) Elective Deferrals (including any Excess Contributions which have been refunded as provided in Section 4.2 herein but excluding excess
deferrals that are distributed in accordance with Treas. Reg. § 1.402(g)-1(e)(2) or (3) but excluding any Employee Contributions described in Section 414(v) of the Code), 
 (3) After Tax Contributions (including any Excess Aggregate Contributions which have been refunded as provided in Section 4.8 herein), 

(4) Forfeitures, 
 (5) Amounts
allocated to an individual medical account, as defined in Section 415(1)(2) of the Code, which is part of a pension or annuity plan maintained by the Employer are treated as annual additions to a defined contribution plan; and amounts derived
from contribution plans or accrued after December 31, 1985, and taxable years ending after such date, which are attributable to post-retirement medical benefits, allocated to the separate account of a key employee, as defined in
Section 419(A)(d)(3) of the Code, under a welfare benefit fund, as defined in Section 419(e) of the Code, maintained by the Employer are treated as annual addition to a defined contribution plan, and 
  

 IV-14 

 (6) Any excess amount applied under Section 4.12(c), Third, in the Limitation Year to reduce
Employer Contributions will be considered Annual Additions for such Limitation Year. 
 If a Participant is covered under another qualified defined
contribution plan maintained by the Employer, Annual Additions which may be credited to the Participant’s Account under this Plan for a Limitation Year will be limited in accordance with the provisions of this Section 4.12 as though the
other plan were a part of this Plan. 
 If, in addition to this Plan, the Participant is covered under another qualified plan which is a defined contribution
plan maintained by the Employer, a welfare benefit fund, as defined in Section 419(e) of the Code maintained by the Employer, or an individual medical benefit account, as defined in Section 415(1)(2) of the Code maintained by the Employer,
which provides for Annual Additions during any Limitation Year, then the Annual Additions which may be credited to a Participant’s Account under this Plan for any such Limitation Year will not exceed the Maximum Permissible Amount reduced by
the Annual Additions credited to a Participant’s Account under the other plans and welfare benefit funds for the same Limitation Year. If the Annual Additions with respect to the Participant under other defined contribution plans and welfare
benefit plans maintained by the Employer are less than the Maximum Permissible Amount and the Employer contribution that would otherwise be contributed or allocated to the Participant’s Account under this Plan would cause the Annual Additions
for the Limitation Year to exceed this limitation, the amount contributed or allocated will be reduced so that the Annual Additions under all such plans and funds for the Limitation Year will equal the Maximum Permissible Amount. If the Annual
Additions with respect to the Participant under such other defined contribution plans and welfare benefit funds in the aggregate are equal to or greater than the Maximum Permissible amount, no amount will be contributed or allocated to a
Participant’s Account under this Plan for the Limitation Year. 
 (ii) Actual Compensation. The words Actual Compensation shall
mean a Participant’s wages, salaries, and fees for professional services and other amounts received without regard to whether or not an amount is paid in cash for personal services actually rendered in the course of employment with the
Employer, to the extent that the amounts are includible in gross income (or to the extent amounts deferred at the election of the Employee would be includible in gross income but for the rules of Sections 125, 132 (for limitation years beginning
after December 31, 2001), 402(e)(3), 402(h)(1)(B), 402(k), or 457(b) of the Code). These amounts include, but are not limited to, commissions paid salesmen, compensation for services on the basis of a percentage of profits, commissions on
insurance premiums, tips and bonuses, fringe benefits, and reimbursements or other expense allowances under a nonaccountable plan as described in Treas. Reg. §1.62-2(c)). Actual Compensation shall be modified as provided below: 
 (1) For purposes of applying the limitations of this Section, Actual Compensation for a Limitation Year is the compensation actually paid or made
available during such Limitation Year. Notwithstanding the preceding sentence to the contrary, Actual 

  

 IV-15 

 
Compensation for a Participant who is permanently and totally disabled (as defined in Section 22(e)(3) of the Code) is the compensation such Participant
would have received for the Limitation Year if the Participant had been paid at the rate of compensation paid immediately before becoming permanently and totally disabled; and, such imputed compensation for the disabled Participant may be taken into
account only if the Participant is not an officer, a director, or highly compensated, and contributions made on behalf of such Participant are nonforfeitable when made. 
 (2) Amounts under Section 125 of the Code include any amounts not available to a Participant in cash in lieu of group health coverage because the Participant is unable to certify that he or she has other health
coverage (deemed Section 125 of the Code compensation). An amount will be treated as an amount under Section 125 of the Code only if the Employer does not request or collect information regarding the Participant’s other health
coverage as part of the enrollment process for the health plan. 
 (iii) Excess Amount: The words “Excess Amount” shall
mean the excess of the Participant’s Annual Additions for the applicable Limitation Year over the Maximum Permissible Amount. 
 (iv)
Limitation Year: The words “Limitation Year” shall mean the calendar year. All qualified plans maintained by the Employer must use the same limitation year. If the limitation year is amended to a different 12 consecutive month
period, the new limitation year must begin on a date within the limitation year in which the amendment is made. If a short Limitation Year is created because of an amendment changing the Limitation Year to a different 12 consecutive month period,
the Maximum Permissible Amount will not exceed the Defined Contribution Dollar Limitations multiplied by the following fraction (number of months in the short Limitation Year/12). 
 (v) Maximum Permissible Amount: Except for Pre-tax Catch-Up Contributions under Section 414(v) of the Code, the words “Maximum
Permissible Amount” shall mean for the applicable Limitation Year, the “maximum permissible amount” which may be contributed or allocated to or made with respect to any Participant which amount shall be the lesser of: 
 (1) $40,000, as adjusted for cost-of-living under Code Section 415(d) (the “Defined Contribution Dollar Limitation”), or 
 (2) 100% of the Participant’s Actual Compensation for the Limitation Year. 
 The compensation limitation referred to above shall not apply to: (1) any contribution for medical benefits (within the meaning of Section 419A(f)(2) of the Code) after separation from service which is
otherwise treated as an Annual Addition, or (2) any amount otherwise treated as an Annual Addition under Section 415(1)(1) of the Code. 
 (b) Determination of Excess. If an excess amount was allocated to a Participant on an Allocation Date of this Plan which coincides with an allocation date of another plan, the excess amount attributed to this Plan will be the product
of (1) the total excess amount 

  

 IV-16 

 
allocated as of such date times (2) the ratio of (i) the Annual Additions allocated to the Participant for the Limitation Year as of such date
under this Plan to (ii) the total Annual Additions allocated to the Participant for the Limitation Year as of such date under this and all other qualified plans which are defined contribution plans. 
 (c) Treatment of Excess. In the event that the Employer determines that there has in fact been an over contribution of an amount (whether or not
previously allocated to a particular Participant’s Account) to which the foregoing Subsections apply as a result of the allocation of Forfeitures, a reasonable error in estimating a Participant’s annual Compensation, or a reasonable error
in determining Excess Elective Deferrals (as defined in Section 4.2(a)), then, in the Limitation Year in which such Excess Amount is discovered, the Excess Amount will be disposed of as follows: 
  

			
	First:	  	Any Excess Amount attributable to 401(k) Contributions and Catch-Up Contributions (and any earnings thereon) to the extent they would reduce the Excess Amount shall be returned to the
Participant.
		
	Second:	  	Any nondeductible voluntary After Tax Contributions (plus attributable earnings), to the extent they would reduce the Excess Amount, will be returned to the Participant;
		
	Third:	  	If the Participant is covered by the Plan at the end of the applicable Limitation Year, the Excess Amount (and earnings thereon) shall be used to reduce Employer Contributions attributable to
such Account for such Participant in the immediately next following Limitation Year, and each succeeding Limitation Year, if necessary, until such Excess Amount (and earnings thereon) have been applied as provided herein. If any Participant is not
covered by the Plan at the end of the applicable Limitation Year, the Excess Amount will be held unallocated in an “Excess Amount Suspense Account” (“Suspense Account”). The Suspense Account will be applied to reduce future
Employer Contributions in the next applicable Limitation Year, and each succeeding Limitation Year thereafter, if necessary. No Excess Amount may be distributed to Participants or former Participants nor shall any amounts held in a Suspense Account
share in any increases or decreases to the Trust Fund as provided under Section 5.2 hereof.

 Section 4.13 Latest Time Contributions Can Be Made. Unless payment to the Plan is specifically
required by applicable law to be made earlier, actual payment of Employer Contributions, 401(k) Contributions, and Special Section 401(k) Contributions may be made following the close of the Employer’s taxable year at any time prior to the
date on which the federal income tax return of the Employer is filed for such taxable year including extensions of time granted for filing such return. 
 Section 4.14 Suspension of Contributions. Nothing in this Plan shall be construed to prevent the Employer from suspending Employer contributions for any period, but such a suspension, whether temporary or permanent, shall not of
itself terminate the Trust. When contributions are completely discontinued, the Benefits of the Participants shall immediately be 100% vested and nonforfeitable, but there shall not be any immediate vesting of Benefits when contributions are
temporarily suspended. 
  

 IV-17 

 Section 4.15 Contributions for Members of an Affiliated Group. Any of the Company or participating affiliates
or subsidiaries who are members of an affiliated group of corporations, as defined in Section 1504 of the Code, may make contributions to the Trust in the manner prescribed by Section 404(a)(3)(B) of the Code; provided the Profit Sharing
Contributions and all Forfeitures of Profit Sharing Contributions shall be allocated among all Participants in the Plan in the manner provided in Article IV hereof on the basis that all such Participants were employed by the Company. 
 Section 4.16 Contributions Under Mistake of Fact. In the case of a contribution which is made by the Employer under a bona fide mistake of fact or a
contribution which is disallowed for deduction under Section 404 of the Code, the Employer shall withdraw the portion of such contribution, attributable to such mistake of fact or denial of deduction, within one year of the mistaken payment or
the date of disallowance of the deduction, whichever applies. Upon such withdrawal of such portion of the contribution by the Employer, the rights of the Participants therein shall cease and come to an end with the same effect as if such portion of
the contribution had never been made. Earnings attributable to such portion of the contribution shall not be returned to the Employer, but losses attributable thereto shall reduce the amount to be so returned. In no event shall the withdrawal of the
amount attributable to any mistaken contribution cause the balance of any Participant’s Account to be reduced to less than the balance which would have been in such Account had such mistaken amount not been contributed. 
  

 IV-18 

 ARTICLE V. 
 ACCOUNTING 
 Section 5.1 Accounts. The Plan Administrator shall establish and maintain Accounts for each
of the Participants. Such Accounts shall be primarily for accounting purposes. The Plan Administrator may delegate the responsibility for the maintenance of such Accounts to the Trustees or others. The Accounts of the Participants shall be adjusted
in accordance with the following Sections of this Article V. 
 Section 5.2 Valuation of Account Balances. The assets in a Participant’s
Account will be valued on a daily basis in accordance with the normal valuation procedures of the Trustee. 
 (a) Valuation of the Trust
Fund. The Plan Administrator shall direct the Trustee, as of each Valuation Date, to determine the net worth of the assets comprising the Trust Fund as it exists on the Valuation Date. In determining such net worth, the Trustee shall value the
assets comprising the Trust Fund at their fair market value (or their contractual value in the case of a Contract or Policy) as of the Valuation Date and shall deduct all expenses for which the Trustee has not yet obtained reimbursement from the
Employer or the Trust Fund. The Trustee may update the value of any shares held in the Participant Directed Account by reference to the number of shares held by that Participant, priced at the market value as of the Valuation Date. 
 (b) Method of Valuation. In determining the fair market value of securities held in the Trust Fund which are listed on a registered stock
exchange, the Administrator shall direct the Trustee to value the same at the prices they were last traded on such exchange preceding the close of business on the Valuation Date. If such securities were not traded on the Valuation Date, or if the
exchange on which they are traded was not open for business on the Valuation Date, then the securities shall be valued at the prices at which they were last traded prior to the Valuation Date. Any unlisted security held in the Trust Fund shall be
valued at its bid price next preceding the close of business on the Valuation Date, which bid price shall be obtained from a registered broker or an investment banker. In determining the fair market value of assets other than securities for which
trading or bid prices can be obtained, the Trustee may appraise such assets itself, or in its discretion, employ one or more appraisers for that purpose and rely on the values established by such appraiser or appraisers. 
 Section 5.3 Separate Accounting Rule for Participant Returning After Break-in-Service. With respect to a Participant who has previously terminated his
employment with the Employer and subsequently again becomes an active Participant after incurring five consecutive one-year Breaks-in-Service, if there remains any unpaid vested Benefit in his Accounts which is attributable to such
Participant’s Plan participation prior to such Breaks-in-Service (“Pre-Break Benefit”), such Pre-Break Benefit shall be held in a separate sub-account within the corresponding Account so that his Pre-Break Benefit and Benefits
attributable to his Plan participation after such Breaks-in-Service are separately accounted for. 
 Section 5.4 Life Insurance Policies. Life
insurance may not be purchased in the Plan. A Participant’s Account holding insurance policies shall be credited as of the Anniversary Date of each Plan Year with the cash value increases in such insurance policies on his life held in the
Trust. Life insurance policies will be purchased on a uniform nondiscriminatory manner and 

  

 V-1 

 
only upon a Participant requesting that such policy be purchased. Once a Participant has been notified of his right to have insurance purchased subject to
limitations contained in this Plan and Trust, the Employer shall have no further obligation to notify such Participant of any subsequent right to purchase such insurance. 
 Section 5.5 Investment Options. The following provisions of this Section shall be applicable to all Accounts: 
 (a) General. Pursuant to Section 404(c) of the Act, with respect to directed investments by the Participants, each Participant in the Plan is hereby given the specific authority to direct the investment of
all or any portion of his Accounts in one or more of the Investment Options (as defined in Subsection (c) below) in accordance with the procedures as described below. For purposes of this Section, the Participants shall be exercising full
investment control, discretion, authority and fiduciary responsibility as provided in this Plan and the related Trust of the investments in such Participants’ applicable Accounts. 
 (b) Election of Investment Options. 
 (i) Elections of Investment Options may be made by each Participant during the Plan Year and shall be effective for periods after the date of such election. An election shall be made in accordance with rules established by the Plan
Administrator. This election shall continue until a subsequent election is made by such Participant or until such Participant’s Benefit represented by all of his Accounts is distributed to him or his Beneficiary, as applicable. A Participant
may change his Investment Options on any day of the Plan Year. 
 (ii) A Participant must make his election of Investment Options by any
means authorized by the Plan Administrator, including telephone or internet (if internet access is approved by the Plan Administrator) instructions. Such election of Investment Options shall become effective as soon as reasonably practicable after
receipt of such election. With respect to this Section, the authority of the Plan Administrator shall be limited to prescribing the form of the Election Notice, informing the Trustee of elections of Investment Options and the types of Investment
Options to be made available to the Participants. 
 (iii) To the extent a Participant has elected to invest his Accounts in an Investment
Option, the Trustee will establish a separate sub-account under the appropriate Account reflecting the selected Investment Option. See Section 5.2 hereof with regard to the valuation of the Accounts in the Investment Option. 
 (iv) In the event the Trustee does not receive a proper direction for the election of an Investment Option, the Accounts of such Participant shall be
invested in the Investment Option designated by the Plan Administrator until the Trustee receives proper direction. 
 (c) Description of
Investment Options. The Investment Options which are offered to the Participants in the Plan shall be the Investment Options designated by the Plan Administrator prior to a Participant’s election and may be modified by the Plan
Administrator; provided, prior to the Plan Administrator’s modification of the Investment Options, the Employer shall notify Participants of such change and provide Participants with such information as is prudent and necessary for Participants
to make informed investment decisions.

 ARTICLE VI. 
 WITHDRAWAL AND DISTRIBUTION OF BENEFITS 
 Section 6.1 Retirement Benefits. 
 (a) Normal or Disability Retirement. Unless sooner vested, a Participant’s Benefit represented by Employer Contributions shall be 100% vested
and nonforfeitable on his Normal Retirement Date or Disability Retirement Date, as the case may be. A Participant shall be entitled to his Benefit in accordance with Section 6.6 herein. 
 (b) Postponed Retirement. Subject to the requirements of Section 401(a)(9) of the Code, if a Participant continues to work beyond his Normal
Retirement Date, the Committee shall postpone payment of his Benefit until the date such Participant actually retires (herein called “Postponed Retirement Date”). Such Participant shall be entitled to his Benefit in accordance with
Section 6.6 herein. The Participant shall continue to share in Employer Contributions, Forfeitures, if any, and increases and decreases to his Accounts determined pursuant to Article V herein like any other Participant until his Postponed
Retirement Date. 
 (c) Participant’s Consent Required for Certain Distributions in Excess of $5,000. Except as otherwise
provided herein, if a Participant’s vested and nonforfeitable Benefit is in excess of $5,000, the Participant must consent to any distribution of his Benefit prior to his Normal Retirement Date (except in case of the Participant’s death),
and, if Qualified Joint and Survivor Annuity provisions apply, the Participant’s spouse must also consent. 
 Section 6.2 Termination of
Employment-Vesting of Accounts. 
 (a) Vesting. 
 (i) Regular Vesting Schedule. Unless sooner vested, a Participant shall have vested and nonforfeitable rights in all or part of his Benefit represented by Employer Contributions, other than Matching
Contributions, as set forth by the percentages in the applicable table hereafter set forth: 
  

							
	 YEARS OF CREDITED
 SERVICE
	 	 PERCENTAGE OF EMPLOYER
 CONTRIBUTIONS VESTED

	Less than:	 	2	 		 	0%
	At least:	 	2	 		 	20%
		 	3	 		 	40%
		 	4	 		 	60%
		 	5	 		 	80%
		 	6	 		 	100%

  

 VI-1 

 (ii) Minimum Vesting on Matching Contributions. This Section shall apply to Participants with
accrued benefits derived from Matching Contributions who complete an Hour of Service under the Plan in a Plan Year beginning after December 31, 2001. A Participant’s accrued benefit derived from Matching Contributions shall vest according
to the following schedule and the election in Section 6.2(h) shall apply: 
  

							
	 YEARS OF CREDITED
 SERVICE
	 	 PERCENTAGE OF EMPLOYER
 CONTRIBUTIONS VESTED

	Less than:	 	2	 		 	0%
	At least:	 	2	 		 	20%
		 	3	 		 	40%
		 	4	 		 	60%
		 	5	 		 	80%
		 	6	 		 	100%

 (iii) Vesting Schedule for Employer Contributions Transferred from the Lincoln National Bank
401(k) Plan. This Section shall apply to Participants with accrued benefits derived from employer contributions transferred from the Lincoln National Bank 401(k) Plan. A Participant’s accrued benefit derived from Matching Contributions
shall vest according to the following schedule and the election in Section 6.2(h) shall apply: 
  

							
	 YEARS OF CREDITED
 SERVICE
	 	 PERCENTAGE OF EMPLOYER
 CONTRIBUTIONS VESTED

	Less than:	 	1	 		 	0%
	At least:	 	1	 		 	20%
		 	2	 		 	40%
		 	3	 		 	60%
		 	4	 		 	80%
		 	5	 		 	100%

 (iv) Top-Heavy Plan Vesting Schedule. If this Plan shall be a Top-Heavy Plan for a
particular Plan Year then, notwithstanding Subsection 6.2(b) to the contrary, unless sooner vested, a Participant shall have vested and nonforfeitable rights in all or part of his Benefit represented by Employer Contributions, as set forth by the
percentages in the table hereafter: 
  

 VI-2 

							
	 YEARS OF CREDITED
 SERVICE
	 	 PERCENTAGE OF EMPLOYER
 CONTRIBUTIONS VESTED

	Less than:	 	2	 		 	0%
	At least:	 	2	 		 	20%
		 	3	 		 	40%
		 	4	 		 	60%
		 	5	 		 	80%
		 	6	 		 	100%

 Once the Plan becomes a Top-Heavy Plan, the Top-Heavy Plan vesting schedule shall continue to be applicable,
notwithstanding the fact that the Plan shall later not be a Top-Heavy Plan. In a subsequent Plan Year, should the Plan cease to be a Top-Heavy Plan, then, any Benefits earned attributable to any Participants in the Plan during such period shall
never be reduced for any reason whatsoever. 
 (b) Payment of Benefit. 
 (i) Cash Out of Small Amounts. If any Participant has $5,000 or less of vested and nonforfeitable Benefit in his Accounts (including rollover
amounts) at the time he terminates his employment, the Plan Administrator may direct the Trustees to pay the entire Benefit in a lump sum and the non-vested portion will be treated as a Forfeiture. If a Participant would have received a distribution
under the preceding sentence but for the fact that the Participant’s vested Account balance (including rollover amounts) exceeded $5,000 when the Participant terminated service with the Employer and if at a later time such Account balance
(including rollover amounts) is reduced such that it is not greater than $5,000, the Plan Administrator may direct the Trustees to pay the entire Benefit in a lump sum and the non-vested portion shall be treated as a Forfeiture. Payment shall be
made within an administratively feasible time after the Participant’s termination of employment which in the normal case will be within six months following the close of the Plan Year in which the Participant terminates his employment or six
months following the close of the Plan Year in which the Participant’s vested and nonforfeitable Benefit in his Account (including rollover amounts) falls below $5,000. 
 (ii) Automatic Rollovers. In the event of a mandatory distribution on and after March 28, 2005 greater than $1,000 in accordance with the
provisions of Subsection 6.2(b), if the Participant does not elect to have such distribution paid directly to an Eligible Retirement Plan specified by the Participant in a direct rollover or to receive the distribution directly in accordance with
Section 6.6, then the Plan Administrator will pay the distribution in a direct rollover to an individual retirement plan designated by the Plan Administrator. For purposes of determining whether a mandatory distribution is greater than $1,000,
the portion of the Participant’s distribution attributable to any rollover contribution is included. 
  

 VI-3 

 (c) Reinstatement of Forfeitures. 
 (i) If a Participant receives a distribution of his vested and nonforfeitable Benefit, and thereafter resumes employment before incurring five
consecutive one-year Breaks-in-Service, his Forfeitures, if previously allocated, shall be restored to the corresponding Account as of the date of distribution if he repays to the Trustees the full amount of any distribution made pursuant to
Subsection 6.2(b) herein any time prior to the date on which the Participant actually incurs five consecutive one-year Breaks-in-Service following the date of distribution. 
 (ii) Subject to Subsection (iii) below, if a Participant has not received a cash out of his vested and nonforfeitable Benefit as provided in
Subsection 6.2(b) herein, no part of his Account shall be considered forfeited under Subsection 6.2(d) herein unless and until the Participant incurs five consecutive one-year Breaks-in-Service. 
 (iii) If a Participant has no vested and nonforfeitable Benefit upon termination of employment with the Employer, the Participant’s entire Benefit
will be forfeited. Provided, however, if a Participant has no vested and nonforfeitable Benefit and he thereafter resumes employment with the Employer before incurring five consecutive one-year Breaks-in-Service, his Forfeitures, if previously
allocated, shall be restored to the corresponding Account. 
 (iv) The foregoing reinstatement provision shall be applicable only if the
Participant has a balance in an Account which is subject to forfeiture herein. The amount restored in any event shall be equal to the forfeitable portion of such Benefit, unadjusted by any subsequent increases and decreases otherwise allocable in
accordance with Section 5.2 herein. 
 (d) When Forfeitures are Final. Forfeitures shall become absolutely forfeited and not
subject to reinstatement for any reason on the first to occur of the following of Subsections (i) and (ii), whichever applies: 
 (i) On
the date the period for repayment as provided in Subsection 6.2(c) herein has expired, or 
 (ii) On the Anniversary Date of the last Plan
Year in which the Participant incurs five consecutive one-year Breaks-in-Service. 
 (e) Sources for Reinstated Forfeitures. If
Forfeitures are to be reinstated for a Participant in accordance with this Section, then such reinstatement shall be made as of the Anniversary Date coinciding with or next following the date upon which the requirements for reinstatement of
forfeitures are met. Reinstated Forfeitures shall be satisfied from the following sources in the priority indicated: (i) unallocated Forfeitures, (ii) unallocated Trust Fund increases, or (iii) Employer Contributions which the
Employer shall make if necessary to satisfy such reinstatement. For purposes of this Subsection (f), the limitations under Section 415 of the Code as set forth under Section 4.12 herein shall not apply. 
 (f) No Forfeitures for Cause. The vested and nonforfeitable Benefit represented by a Participant’s Accounts shall not be forfeited for any
cause whatsoever. 
  

 VI-4 

 (g) Minimum Vested Rights of Previous Participants. The vesting schedule under Subsection 6.2(b)
herein shall apply to all Participants after the Effective Date hereof, but such schedule shall not be construed to divest a Participant of his vested percentage earned up through the Anniversary Date preceding the Effective Date hereof. 

(h) Amendment to Vesting Schedule. If the Plan’s vesting schedule is amended, or the Plan is amended in any way that directly or
indirectly affects the computation of the Participant’s nonforfeitable percentage in his Benefit or if the Plan is deemed amended by an automatic change to or from a Top-Heavy Plan vesting schedule, each Participant with at least three years of
Credited Service with the Employer may elect, within a reasonable period after the adoption of the amendment or change, to have the nonforfeitable percentage computed under the Plan without regard to such amendment or change. The period during which
election may be made shall commence with the date the amendment is adopted or deemed to be made and shall end on the latest of: 
 (i) 60
days after the amendment to the Plan is adopted; 
 (ii) 60 days after the amendment becomes effective; or 
 (iii) 60 days after the Participant is issued written notice of the amendment by the Employer or the Plan Administrator. 
 Section 6.3 Death Benefits. 
 (a) Death of
Participant. Unless sooner vested, an active Participant’s Benefit represented by his Accounts shall be 100% vested and nonforfeitable upon his death. Upon the death of a Participant, the Plan Administrator shall cause distribution of his
Benefit under Section 6.5 herein to the Beneficiary. 
 (b) Designation of Beneficiary Other Than Spouse. Each Participant may
complete a form provided by the Plan Administrator to name a Beneficiary under the Plan. If the Participant is married at the time of his or her death, the Beneficiary shall be the Participant’s surviving spouse unless the Participant has named
a non-spouse beneficiary and has complied with the following Section 6.3(d). If the Participant is not married at his or her death, the Benefit shall be paid to the Participant’s estate if no Beneficiary has been named. The provisions of
this Section shall apply to Participants dying on or after the Effective Date. 
 (c) Payment of Benefit. Unless an alternate method
of payment is selected by the surviving spouse or other Beneficiary as provided herein, another form of benefit is required by law or the spouse of the Participant otherwise consents, then, upon the death of a Participant, the Participant’s
Benefit shall be automatically paid to the Participant’s surviving spouse or other Beneficiary named by the Participant in the form of a lump sum. 
 (d) Other Conditions. Payments to a surviving spouse or other Beneficiary named by the Participant made pursuant to Subsection (b) above shall be made within a reasonable time following the death of the
Participant. If the form of payment of Benefits under Subsection (b) above shall be in a form other than a Qualified Spouse’s Survivor Annuity or if payment of Benefits is to a designated Beneficiary under Subsection (b) above other
than such 

  

 VI-5 

 
Participant’s surviving spouse, then, the written consent of such spouse, or a qualified waiver of consent, must be obtained. If there is no surviving
spouse or other Beneficiary, the Benefit shall be paid to the deceased Participant’s estate. Upon the death of a Participant prior to the date payment of his Benefits would otherwise commence pursuant to the terms of the Plan, Benefits will
commence as soon as practicable thereafter as provided in Subsection 6.1(a) hereof as though the Participant had retired on the day he died and such Benefits shall be paid to the surviving spouse or designated Beneficiary, as the case may be, all as
determined within this Section. 
 (i) Upon the death of the Participant, the surviving spouse or other Beneficiary, as the case may be,
shall have the option to select any method of payment under Section 6.6 herein. 
 (ii) With respect to any required consent of a
spouse under this Section, the spouse’s consent must be in writing and witnessed by a Plan Administrator member or notary public. Notwithstanding this consent requirement, if the Participant establishes to the satisfaction of the Plan
Administrator that such written consent cannot be obtained because there is no spouse or the spouse cannot be located, such consent requirement shall be deemed waived (“qualified waiver of consent”). Any consent necessary under this
Section shall be valid only with respect to the spouse who signs the consent, or in the event of a qualified waiver of consent, the designated spouse who cannot be located. Additionally, a revocation of a prior waiver under this Subsection may be
made in writing to the Plan Administrator by a Participant without the consent of the spouse at any time before the commencement of benefits. The number of revocations shall not be limited. The word “spouse” shall include a former spouse
but only to the extent provided under a “qualified domestic relations order” as described in Section 414(p) of the Code. 
 (e) Form of Benefit for Unmarried Participant. In the event a Benefit is to be paid to a Participant who is not married on the date his Benefit would otherwise commence, then, subject to a contrary election by the Participant or
designated Beneficiary (in the case of death), such Participant or Beneficiary will be automatically paid his Benefits in the form of a lump sum. 
 (f) Life Insurance Policies. With respect to death benefits payable under insurance policies held in a Participant’s Account, upon the death of a Participant who has an insurance policy issued on his life, the Trustees shall be
the owners of and designated beneficiaries under any such insurance policy and shall be entitled to receive death benefits. There shall be appropriate adjustment under Subsection 6.4(b) herein in determining a deceased Participant’s final
Benefit, which along with other amounts constituting such final Benefit shall be distributable to the Participant’s Beneficiary under Section 6.6 herein. Further, all of such death Benefits shall be segregated and shall be payable to the
Beneficiary. 
 Section 6.4 Determining Final Benefit. 
 (a) All Accounts. With respect to Benefits payable under either of Sections 6.1, 6.2, or 6.3 herein, a Participant’s Accounts shall be determined as of the Valuation Date, coinciding with or immediately
preceding the date that payment of Benefits commence. Any undistributed balance on a Valuation Date shall continue to be credited with its allocable share of increases or decreases thereon determined pursuant to Section 5.2 herein. 

 

 VI-6 

 (b) Insurance Policies. In the event that a Participant who is insured under any insurance policy
on his life, held in the Trust, dies prior to his Normal Retirement Date, then his Account holding insurance policies shall be adjusted upwards by any excess by which the face value of the insurance policy payable at his death to the Trustees, as
beneficiary, exceeds the cash value of such policy. The Participant, at the time of his termination of employment, may make a request to the Plan Administrator that any insurance policy issued on his life shall be distributed to him as part of his
Benefit, or such Participant may request the Plan Administrator to withdraw the cash value, if any, attributable to such policy and add such cash value to his Benefit and then have transferred to him such policy without the cash value. 

Section 6.5 Latest Time When Payment of Benefits Must Commence. 
 (a) Time for Payment. With respect to Benefits becoming payable on account of a retirement, death or other termination of employment, as the case may be, and subject to an election in Section 6.5(b),
distribution in any event shall commence not later than the 60th day following the close of the Plan Year in which the last of the following events occur: a Participant attains his Normal Retirement Date or the age of at least 65 years; the
Participant terminates his employment service with the Employer; or, the 10th anniversary of the Plan Year in which the Participant commenced participation in the Plan. 
 (b) Deferral of Benefits. Subject to Section 401(a)(9) of the Code and the related provisions herein, prior to the time the right to receive a Benefit under this Section becomes absolutely payable, a
Participant may file a written election with the Plan Administrator to defer his Benefit. Such election shall be irrevocable by the Participant and shall describe his Benefit and the date on which payment of such Benefit shall commence.
Notwithstanding the foregoing, the failure of a Participant to consent to a distribution within the time periods set forth above shall be deemed to be an election to defer the commencement of payment of any benefit sufficient to satisfy this
Section. 
 Section 6.6 Methods of Distribution. 
 (a) General. Subject to the requirements of Section 401(a)(9) of the Code, Benefits shall be distributed in accordance with the following Subsections. Participant may elect to receive their Benefits
invested in Employer common stock in kind. Payment for fractional shares shall be made in cash. Any other distribution may be made in kind or in cash or partly in kind or in cash as determined by the Participant or Beneficiary. The Participant
solely shall have the power to determine the manner in which Benefits are to be distributed hereunder in the best interests of such Participant or his Beneficiary and may, in his sole discretion, upon the written application of the Participant or a
Beneficiary, direct the Trustees to distribute Benefits pursuant to any one of the manner of payments provided in Subsection 6.6(b) hereafter. 
  

 VI-7 

 (b) Methods. All distributions hereunder may be made in one or more of the following manners:

 (i) In one or more lump sum payments which may be part or all of a Participant’s Account; or 
 (ii) In substantially equal payments in monthly, quarterly, semi-annual or annual installments; provided, an installment election must be for a period
less than the life expectancy of the Participant or his Beneficiaries. The Participant or Beneficiary may accelerate the payment of any unpaid installments; provided, such payments shall not exceed the Participant’s or Beneficiary’s
remaining account balance. 
 (c) Special Rules for Distributions. In accordance with Section 1.411(a)-11(c) of the Income Tax
Regulations, the Plan Administrator shall provide to the Participant a notice setting forth the following: (i) a general description of the material features and an explanation of the relative values of the optional forms of benefit available
under the Plan in a manner that would satisfy the notice requirements of Section 417(a)(3) of the Code and (ii) the Participant’s right, if any, to defer receipt of the distribution. Such notice must be provided to a Participant no
less than 30 days and no more than 90 days before the distribution starting date or annuity starting date, as applicable. Written consent of the Participant to the distribution must not be made before the Participant receives such notice and must
not be made more than 90 days before the distribution starting date or annuity starting date, as applicable. If a distribution is one to which Sections 401(a)(11) and 417 of the Code do not apply, such distribution may commence less than 30 days
after the notice required under Section 1.411(a)-11(c) of the Income Tax Regulations is given, provided that: (i) the Plan Administrator clearly informs the Participant that the Participant has a right to a period of at least 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.

 (d) Distribution Prior to Age 59 1/2. In the event of a premature distribution to a Participant prior to his attaining age 59 1
/2, part or all of such distribution may be subject to a 10% excise tax. 
 (e) No Reduction of Benefits. In the event that the Plan has been classified as a Top-Heavy Plan, then, in a subsequent Plan Year, should the Plan
cease to be a Top-Heavy Plan, then, any Benefits earned attributable to any Participants in the Plan during such period shall never be reduced for any reason whatsoever. 
 (f) Limitation on Time of Distributions. Unless otherwise permitted under Section 401(k) of the Code or other provisions of the Plan, no Benefit which is attributable to any of a Participant’s
Accounts shall be distributed to such Participant or his Beneficiary earlier than the first to occur of the attainment of his Normal Retirement Date, Disability Retirement Date, death, severance from employment with the Employer, or hardship; and,
no such distribution will be made solely by reason of the completion of a stated period of participation or the lapse of a fixed number of years of participation in the Plan.

 Section 6.7 Required Minimum Distributions. The provisions of this Section 6.7 will apply for purposes
of determining Required Minimum Distributions for distribution calendar years beginning with the 2003 calendar year, as well as Required Minimum Distributions for the 2002 Distribution Calendar Years that are made on or after August 1, 2002.
The requirements of this Section will take precedence over any inconsistent provisions of the Plan. All distributions required under this Section will be determined and made in accordance with the Treasury regulations under Section 401(a)(9) of
the Code. Notwithstanding the other provisions of this Section, distributions may be made under a designation made before January 1, 1984, in accordance with Section 242(b)(2) of the Tax Equity and Fiscal Responsibility Act (TEFRA) and the
provisions of the Plan that relate to Section 242(b)(2) of TEFRA. 
 (a) Coordination with Minimum Distribution Requirements
Previously in Effect. If this Section specifies an effective date that is earlier than calendar years beginning with the 2003 calendar year, Required Minimum Distributions for 2002 under this Section will be determined as follows. If the total
amount of 2002 Required Minimum Distributions under the Plan made to the distributee prior to the effective date of this Section equals or exceeds the Required Minimum Distributions determined under this Section, then no additional distributions
will be required to be made for 2002 on or after such date to the distributee. If the total amount of 2002 Required Minimum Distributions under the Plan made to the distributee prior to the effective date of this Section is less than the amount
determined under this Section, then Required Minimum Distributions for 2002 on and after such date will be determined so that the total amount of Required Minimum Distributions for 2002 made to the distributee will be the amount determined under
this Section. 
 (b) Time and Manner of Distribution. 
 (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. For purposes of this Section, the “Required Beginning Date” of a Participant (except for a Participant who is a 5-Percent Owner) is
the April 1 of the calendar year following the later of the April 1 of the calendar year following the calendar year in which the Participant attains age 70 1/2
 or retires. The Required Beginning Date of a Participant who is a 5-Percent Owner is the April 1 following the calendar year in which the Participant attains age 70 1
/2, without regard to whether he has terminated employment. A Participant is treated as a 5-Percent Owner for purposes of this paragraph if such Participant is
a 5-Percent Owner of an Employer as defined in Section 416 of the Code at any time during the Plan year ending with or within the calendar year in which such owner attains age 70 1/2. Once distributions have begun to a 5-Percent Owner under this paragraph, they must continue to be distributed, even if the Participant ceases to be a 5-Percent Owner in
a subsequent year. 
 (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: 
 (1) If the Participant’s surviving spouse is the Participant’s sole designated
Beneficiary, then, 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. 
  

 VI-9 

 (2) If the Participant’s surviving spouse is not the Participant’s sole designated
Beneficiary, then, distributions to the designated Beneficiary will begin by December 31 of the calendar year immediately following the calendar year in which the Participant died. 
 (3) 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. 
 (4) 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 Subsection (ii), other
than Subsection (ii)(1), will apply as if the surviving spouse were the Participant. 
 For purposes of this Subsection (b) and Subsection (d), unless
Subsection (ii)(4) applies, distributions are considered to begin on the Participant’s Required Beginning Date. If Subsection (ii)(4) applies, distributions are considered to begin on the date distributions are required to begin to the
surviving spouse under Subsection (ii)(4). 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 (ii)(4)), the date distributions are considered to begin is the date distributions actually commence. 
 (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: 
 (1) the quotient obtained by dividing the Participant’s
Account balance by the distribution period in the Uniform Lifetime Table set forth in Section 1.401(a)(9)-9 of the Treasury regulations, using the Participant’s age as of the Participant’s birthday in the distribution calendar year;
or 
 (2) 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 Account balance by the number in the Joint and Last Survivor Table set forth in Section 1.401(a)(9)-9 of the Treasury regulations, 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 Subsection (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. 
  

 VI-10 

 (d) Required Minimum Distributions After Participant’s Death. 
 (i) Death On or After Date Distributions Begin. 
 (1) 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 Account balance 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 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. 
 (2) 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 Account balance 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. 
 (ii) Death Before Date Distributions Begin. 
 (1) Participant Survived by Designated Beneficiary. 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 Account balance by the remaining life expectancy
of the Participant’s designated Beneficiary, determined as provided in Subsection (c). 
 (2) 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 

  

 VI-11 

 
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. 
 (3) 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 Subsection (b)(ii)(1), this Section 6.7 will apply as if the surviving spouse were the Participant. 
 (e) Definitions. 
 (i) Designated Beneficiary. The individual who is designated as the
Beneficiary under Section 6.3(b) of the Plan and is the designated Beneficiary under Section 401(a)(9) of the Internal Revenue Code and Section 1.401(a)(9)-1, Q&A-4, of the Treasury regulations. 
 (ii) Distribution Calendar Year. A Calendar Year for which a minimum distribution is required. For distributions beginning before the
Participant’s death, the first distribution Calendar Year is the calendar year immediately preceding the Calendar Year which contains the Participant’s Required Beginning Date. For distributions beginning after the Participant’s
death, the first Distribution Calendar Year is the calendar year in which distributions are required to begin under Subsection (b)(ii). The Required Minimum Distribution for the Participant’s first Distribution Calendar Year will be made on or
before the Participant’s Required Beginning Date. The Required Minimum Distribution for other Distribution Calendar Years, including the Required Minimum Distribution for the Distribution Calendar Year in which the Participant’s Required
Beginning Date occurs, will be made on or before December 31 of that distribution calendar year. 
 (iii) Life Expectancy. Life
Expectancy as computed by use of the Single Life Table in Section 1.401(a)(9)-9 of the Treasury regulations. 
 (iv)
Participant’s Account Balance. The Account Balance as of the last valuation date in the calendar year immediately preceding the distribution calendar year (valuation calendar year) increased by the amount of any contributions made and
allocated or forfeitures allocated to the Account Balance as of dates in the valuation calendar year after the valuation date and decreased by 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. 
 Section 6.8 Additional Benefit Provisions. 
 (a)
Information Required on Distribution. Preparatory to commencing distribution with respect to any person, the Plan Administrator shall notify the Trustees of the following information: (i) the Participant’s or Beneficiary’s name
and address; (ii) the date on which the Participant’s employment terminated; (iii) the reason for the Participant’s termination; (iv) the name and address of the person or persons to whom the distribution is to be made;
(v) the time or times of distribution; (vi) the form of the distribution; (vii) the amounts to be distributed; and (viii) such other information as may be reasonably necessary. 
  

 VI-12 

 (b) Instructions From Plan Administrator. Distribution shall be made only upon receipt of
instructions from the Plan Administrator and the Trustees shall have no responsibility whatsoever in determining the propriety of such distributions when made pursuant to said instructions. 
 (c) No Reduction of Benefits on Account of Merger, Consolidation or Transfer of Trust Fund. In the case of any merger or consolidation with, or
transfer of the assets or liabilities to any other plan, each Participant in the Plan would (if the Plan then terminated) receive a Benefit immediately after such merger, consolidation or transfer (if the Plan had then terminated) which is at least
equal to the Benefit such Participant was entitled to immediately before such merger, consolidation or transfer. The preceding sentence shall not apply to any multiemployer plan with respect to any transaction to the extent that the Participants
either before or after the transaction are covered under a multiemployer plan to which Title IV of the Act applies. 
 (d) No Insurance
Policies After Normal Retirement Date. When a Participant reaches his Normal Retirement Date, any insurance policies on his life shall be converted to cash and the proceeds thereof held in his Account with any other amounts until he is entitled
to distribution of his Benefit. 
 (e) No Reduction of Benefits on Account of Social Security Increases. In the case of a Participant
or Beneficiary who is receiving Benefits under the Plan, such Benefits shall not be decreased by reason of any increase in the benefit levels payable under Title II of the Social Security Act or any increase in the wage base under such Title II, if
such increase takes place after the date of the enactment (September 2, 1974) of the Act or (if later) the earlier of the date of first receipt of such Benefits or the date of severance from employment of the Employer, as the case may be.

 Section 6.9 Payments Under a Qualified Domestic Relations Order. 
 (a) General. The Plan Administrator shall follow the terms of any “qualified domestic relations order” as defined in Subsection (b) below (“QDRO”) issued with respect to a Participant
where such QDRO grants to an “Alternate Payee” rights in the Benefit of the Participant. An Alternate Payee includes any spouse, former spouse, child, or other dependent of a Participant who is recognized by a QDRO as having a right to
receive all, or a portion of the Benefits payable under the Plan with respect to the Participant. The Plan Administrator shall only follow QDROs which meet all of the requirements of this Section. 
 (b) Definition of QDRO. A QDRO defined under Section 414(p) of the Code is any judgment, decree or order, including the approval of a
property settlement agreement, provided that: 
 (i) The QDRO relates to the provision from a Participant’s Benefit of child support,
alimony or marital property rights to or for the benefit of an Alternate Payee and is made pursuant to a state domestic relations law (including community property laws, if applicable); 
  

 VI-13 

 (ii) The QDRO specifies the name and last known mailing address (if any) of the Participant and each
Alternate Payee covered by the QDRO; 
 (iii) The QDRO precisely specifies the amount or percentage of the Participant’s Benefit to be
paid to each Alternate Payee or the manner in which the amount or percentage is to be determined; 
 (iv) The QDRO specifies the number of
payments or the period to which the QDRO applies; 
 (v) The QDRO specifically names this Plan as the “plan” to which the QDRO
applies; 
 (vi) The QDRO does not require this Plan to provide (1) any type or form of Benefits, or option not otherwise provided
under this Plan, (2) any increase in Benefits (determined on the basis of actuarial value), or (3) payment of Benefits to an Alternate Payee which are required to be paid to another “alternate payee” under another QDRO; and

 (vii) A QDRO can specify that the payment shall be made at any time (either before or after a Participant’s “earliest
retirement age”); provided, if it does not so specify, payments under a QDRO shall begin immediately, as authorized under the Plan. “Earliest retirement age” shall be the earlier of (1) the date on which the Participant is
entitled to a distribution of Benefits from the Plan, or (2) the later of the date the Participant attains age 50 or the earliest date on which the Participant could obtain a distribution from the Plan if the Participant were separated from
service. The amount payable under a QDRO shall be in the form of a lump sum payment. Subsection (d) hereof sets forth the procedures under which the Plan Administrator shall determine whether a QDRO properly qualifies. 
 (c) Time for Payment of Benefits Under a QDRO. In the event that the Plan Administrator is in receipt of a QDRO which requires that the Plan
Administrator make such distribution, and such QDRO otherwise satisfies the provisions of this Section and Section 414(p) of the Code, then, the Plan Administrator shall make the distribution to the Alternate Payee within a reasonable time
following the date on which the Plan Administrator has (1) received the QDRO and (2) determined that the QDRO satisfies the requirements of this Section and Section 414(p) of the Code. Provided, for purposes of determining the value
of the Participant’s Benefit which is to be distributed pursuant to such QDRO, the Plan Administrator shall determine the Participant’s Benefit as of the Valuation Date coinciding with or first preceding the payment date specified in the
QDRO. Provided further, any distribution made pursuant to this Section prior to the Participant’s Earliest Retirement Age shall be deemed to be made pursuant to the occurrence of a “stated event.” 
 (d) Duties of Plan Administrator. In administering this Section and subject to the restrictions contained in this Section and the Plan, the Plan
Administrator shall perform the following: 
 (i) The Plan Administrator shall furnish a standard form of QDRO to a Participant or any other
person on request. The QDRO may provide for an immediate lump sum payment of the present value of the amount of the Benefit to which the Alternate Payee is determined to be entitled. If this form is used without substantial modification and is
incorporated in a judgment, decree or order described in Subsection (b) hereof which on its face appears to be valid, the Plan Administrator shall treat it as a QDRO and shall pay Benefits to the Alternate Payee in accordance with its terms. If
this procedure is not followed, the Alternate Payee must wait until the time described in Subsection (b)(vii) before Benefits which are not in pay status can become payable to the Alternate Payee. 
  

 VI-14 

 (ii) The Plan Administrator shall not treat any judgment, order or decree as a QDRO unless it meets all
of the requirements set forth in Subsection (b) and (c) hereof and is sufficiently precise and unambiguous so as to preclude any interpretative disputes. If the QDRO meets these requirements, the Plan Administrator shall follow the terms
of the QDRO whether or not this Plan has been joined as a party to the litigation out of which the QDRO arises. 
 (iii) If the Participant
dies before the Earliest Retirement Age, the Alternate Payee will be entitled to Benefits only if the QDRO specifically requires survivor benefits to be paid in the event of the death of the Participant. In the case of a QDRO providing for the
payment of Benefits after the Earliest Retirement Age, the payments to the Alternate Payee at the time are computed as if the Participant had terminated employment on the date on which payment of Benefits commence under the QDRO. 
 Section 6.10 Hardship Withdrawal; In-Service Distributions. 
 (a) General. Upon written application submitted to the Plan Administrator, a Participant who
has attained at least age 65, or who suffers “hardship” (defined hereafter), may withdraw up to 100% of his 401(k) Contribution Account (determined as of the Valuation Date coinciding with or immediately preceding such request). In
addition, a Participant with benefits accrued under the Wilcox & Jones, Inc. 401(k) Retirement Savings Plan or the Lincoln National Bank 401(k) Plan and Trust may withdraw all or any part of his or her vested balance in his or her Account
transferred from either such Plan upon attaining age 59  1/2. 
 (i) “Hardship” exists if he establishes to the satisfaction of the Plan Administrator that such a withdrawal is required to prevent
financial hardship to the Participant. For purposes of this Section, a distribution will be on account of hardship if the distribution is necessary in light of “immediate and heavy financial needs” of the Participant. A distribution based
upon financial hardship cannot exceed the amount required to meet the immediate financial need created by the hardship and not reasonably available from other resources of the Participant. The decision of the Plan Administrator shall be final and
conclusive, and such decision shall be made in a uniform and nondiscriminatory manner among all such eligible Participants. 
 (ii)
Immediate and Heavy Financial Need. The determination of whether a Participant has an immediate and heavy financial need is to be made on the basis of all relevant facts and circumstances. For example, the need to pay the funeral expenses of
a family 

  

 VI-15 

 
member would constitute an immediate and heavy financial need. A distribution made to a Participant for the purchase of a boat or television would generally
not constitute a distribution made on account of an immediate and heavy financial need. A financial need shall not fail to qualify as immediate and heavy merely because such need was reasonably foreseeable or voluntarily incurred by the Participant.

 (iii) Safe Harbor Rule - Deemed Immediate and Heavy Financial Need. A distribution will be deemed to be made on account of an
immediate and heavy financial need of the Participant if the distribution is on account of: 
 (1) Medical expenses described in
Section 213(d) of the Code incurred by the Participant, the Participant’s spouse, or any dependents of the Participant (as defined in Section 152 of the Code; 
 (2) Purchase (excluding mortgage payments) of a principal residence for the Participant; 
 (3) Payment of tuition for the next 12 month period of post-secondary education for the Participant, his or her spouse, children, or dependents;

 (4) The need to prevent the eviction of the Participant from his principal residence or foreclosure on the mortgage of the
Participant’s principal residence; 
 (5) Payments for burial or funeral expenses for the Employee’s deceased parent, spouse,
children or dependents (as defined in Code Section 152 of the Code, and, for taxable years beginning on or after January 1, 2005, without regard to Code Section 152(d)(1)(B) of the Code); or 
 (6) Expenses for the repair of damage to the Employee’s principal residence that would qualify for the casualty deduction under Code
Section 165 of the Code (determined without regard to whether the loss exceeds 10% of adjusted gross income). 
 (7) As otherwise
provided by the rules and regulations promulgated by the Internal Revenue Service; provided however, that an immediate and heavy financial need related to a beneficiary who is not the spouse or a dependent of the Participant shall not be the basis
for making a hardship withdrawal. 
 This list of deemed immediate and heavy financial needs may be expanded without amendment to the Plan through the
publication of Revenue Rulings, Internal Revenue Service Notices, or similar pronouncements of general applicability promulgated by the Internal Revenue Service. 
 (b) Distribution Necessary to Satisfy Financial Need. 
 (i) A distribution will not be treated as
necessary to satisfy an immediate and heavy financial need of a Participant to the extent the amount of the distribution is in excess of the amount required to relieve the financial need or to the extent such need may be satisfied from other
resources that are reasonably available to the Participant. This determination generally is to be made on the basis of all relevant facts and circumstances. A distribution generally may be treated as necessary to satisfy a financial need if the
Employer reasonably relies upon the Participant’s representation that the need cannot be relieved: 
  

 VI-16 

 (1) Through reimbursement or compensation by insurance or otherwise, 
 (2) By reasonable liquidation of the Participant’s assets, to the extent such liquidation would not itself cause an immediate and heavy financial
need, 
 (3) By cessation of 401(k) Contributions, or 
 (4) By other distributions or nontaxable (at the time of the loan) loans from plans maintained by the Employer or by any other employer, or by borrowing from commercial sources on reasonable commercial terms.

 For purposes of this Subsection, the Participant’s resources shall be deemed to include those assets of his spouse and minor children
that are reasonably available to the Participant. For example, a vacation home owned by the Participant and the Participant’s spouse, whether as community property, joint tenants, tenants by the entirety, or tenants in common, will be deemed a
resource of the Participant. However, property held for the Participant’s child under an irrevocable trust or under the Uniform Gifts to Minors Act (as enacted and applicable in a state) will not be treated as a resource of the Participant.

 (ii) Distribution Deemed Necessary to Satisfy Financial Need. A distribution will be deemed to be necessary to satisfy an
immediate and heavy financial need of a Participant if all of the following requirements are satisfied: 
 (1) The distribution is not in
excess of the amount of the immediate and heavy financial need of the Participant, 
 (2) The Participant has obtained all distributions,
other than hardship distributions, and all nontaxable loans currently available under all plans maintained by the Employer, 
 (3) The Plan,
and all other plans maintained by the Employer, provide that the Participant’s contributions to such plans will be suspended for at least 6 months after receipt of the hardship distribution, and 
 (4) The Plan, and all other plans maintained by the Employer, provide that the Participant may not make elective contributions for the
Participant’s taxable year immediately following the taxable year of the hardship distribution in excess of the applicable limit under Section 402(g) of the Code for such next taxable year less the amount of such Participant’s
elective contributions for the taxable year of the hardship distribution. 
 A Participant shall not fail to be treated as an eligible Participant for
purposes of this Section and Section 4.1 hereof merely because he is suspended in accordance with this provision. Additional methods under which distributions will be deemed to be necessary to satisfy an immediate and heavy financial need may
be expanded without amendment to the Plan through the publication of Revenue Rulings, Internal Revenue Service Notices, or similar pronouncements of general applicability promulgated by the Internal Revenue Service. 
  

 VI-17 

 (c) Limitation on Elective Deferrals. Once a Participant makes a “hardship withdrawal”
as provided under this Section, then, such Participant shall not be permitted to make any Elective Deferrals or After Tax Contributions or any other contributions under this Plan and all other plans maintained by the Employer which includes stock
option plans, stock purchase plans, qualified and nonqualified deferred compensation arrangements and any other similar arrangements for six (6) months after the date of such “hardship withdrawal”; provided, employee contributions
under a contributory defined benefit plan or contributory health and welfare plan may continue to be made during such six (6) month period. 
 (d) No Withdrawal of Earnings After 1988. A hardship distribution under this Section shall not include earnings on 401(k) Contributions credited after the last day of the last Plan Year beginning prior to January 1, 1989, and
may not include Matching Contributions and Special Section 401(k) Contributions, nor any earnings on such contributions, irrespective of when credited. 
 Section 6.11 Withdrawal of Participant’s After Tax Contributions. 
 (a) General. A Participant may file with
the Plan Administrator an Election Notice to withdraw all or part of the Benefit represented by his contributions made to his After Tax Contribution Account. No forfeitures will occur solely as a result of the Participant’s withdrawal of all or
part of the Benefit represented by his After Tax Contribution Account. After receipt of the Election Notice, the Plan Administrator shall cause the Trustees to pay over the designated amount in not less than 90 days from the date such Election
Notice shall have been delivered to the Plan Administrator; provided, in the event of a withdrawal by a Participant of part or all of his After Tax Contribution Account balance, such Participant (if continued as an Employee) shall be prohibited from
making further After Tax Contributions for 12 calendar months following the date of such withdrawal of After Tax Contributions. 
 (b)
After Tax Contributions - Prior to January 1, 1987. All After Tax Contributions made prior to January 1, 1987, will be maintained in a separate subaccount (the “Pre 1987 Account”) which is part of the Participant’s
After Tax Contribution Account. Withdrawals made from the Pre 1987 Account made under Subsection (a) above will not include any earnings attributable to such Pre 1987 Account. 
 (c) After Tax Contributions - After December 31, 1986. All After Tax Contributions made after December 31, 1986 will be maintained in a
separate subaccount (the “After 1986 Account”) which is part of the Participant’s After Tax Contribution Account. Distributions made from the After 1986 Account as provided under Subsection (a) above will include earnings
attributable to such After 1986 Account. The amount of earnings on After Tax Contributions which must be distributed with each distribution will be calculated by multiplying the total amount of earnings then held in the After 1986 Account by a
fraction the numerator of which is the amount of After Tax Contributions which is included in the distribution and the denominator of which is the balance of all After Tax Contributions then held in the After 1986 Account. 
  

 VI-18 

 ARTICLE VII. 
 PROVISIONS RELATING TO PARTICIPANTS 
 Section 7.1 Information Required of Participants. Payment of
Benefits shall begin as of the payment date(s) provided in this Plan, and no formal claim shall be required therefor; provided, in the interests of orderly administration of the Plan, the Plan Administrator may make reasonable requests of
Participants and Beneficiaries to furnish information which is reasonably necessary and appropriate to the orderly administration of the Plan, and, to that limited extent, payments under the Plan are conditioned upon the Participants and
Beneficiaries promptly furnishing true, full and complete information as the Plan Administrator may reasonably request. 
 Section 7.2
Participants’ Right in Trust Fund. No Participant or other person shall have any interest in, or right to, any part of the earnings of the Trust Fund, or any part of the Trust Assets thereof, except as and to the extent expressly
provided in the Plan and Trust. 
 Section 7.3 Notification of Benefits. Each Participant and Beneficiary of a deceased Participant shall file in
writing with the Committee from time to time his address and each change of address. Any communication addressed to a Participant or Beneficiary at his last address filed with the Committee, or if no such address was filed, then at his last address
as shown on the Employer’s records, shall be binding on the Participant or his Beneficiary for all purposes of the Plan. If the Committee furnishes notice to any Participant or Beneficiary that he is entitled to a distribution pursuant to the
Plan and the Participant or Beneficiary fails to claim such distribution or make his whereabouts known to the Committee within three (3) years thereafter, the share shall be disposed of as follows: 
 (a) If a Participant is missing but the whereabouts of his Beneficiary is known to the Committee, the Committee shall direct the Trustee to make payment
to such Beneficiary; or 
 (b) If the whereabouts of such Participant and his Beneficiary is unknown to the Committee, the Committee shall
direct the Trustee to make the distribution of the Participant’s share or balance thereof to the Participant’s then surviving heirs-at-law as determined under the statutes and case law of Oklahoma which are in effect at that time as if the
Participant had died immediately upon the expiration of such three (3) year period. 
 Section 7.4 Benefits Payable to Incompetents. Any
payments due hereunder to a minor or other person under legal disability may be made, at the discretion of the Plan Administrator, (i) directly to the said person, or (ii) to a parent, spouse, relative by blood or marriage, or
(iii) the legal representative of the said person. The Plan Administrator shall not be required to see to the application of any such payment, and the payee’s receipt shall be a full and final discharge of all responsibility hereunder of
the Employer, the Plan Administrator and the Trustees. 
 Section 7.5 Conditions of Employment Not Affected by Plan. The establishment and
maintenance of the Plan shall not be construed as conferring any legal rights upon any Employee to the continuation of employment with the Employer, nor shall the Plan interfere with the right of the Employer to discharge any Employee, with or
without cause. 
  

 VII-1 

 Section 7.6 Loans to Participants. 
 (a) General. The Plan Administrator, in its sole discretion, may direct Trustees to make loans to Participants or Beneficiaries who incur a
hardship as defined in Section 6.10, upon the written direction, or such other method acceptable to the Plan Administrator, and application of the Participant who desires to effect such loan. All such loans (i) shall not be made available
to HCEs (as defined in Section 414(q) of the Code) in an amount greater than the amount made available to other Employees, (ii) shall be available to all Participants and Beneficiaries on a nondiscriminatory basis, (iii) shall be made
available in an amount equal to the lesser of 50% of the borrowing Participant’s vested Benefit in his Account or $50,000, (iv) shall be secured by the borrowing Participant’s Benefit Account balance attributable to his Account,
(v) shall be amortized and repaid in level payments of principal and interest made not less frequently than quarterly over the term of the loan, (vi) shall be repaid by payroll reduction or may be prepaid in any manner permitted by the
Plan administrator; (vii) shall accelerate and be due in full on the date a Participant terminates employment with the Employer; (viii) shall not be less than $1,000 in amount each; and (ix) shall be made upon such other reasonable
terms which the Plan Administrator shall designate, such terms being applied in a nondiscriminatory fashion; provided, in no event shall any loan have a term in excess of five years unless such loan is used to purchase any dwelling which within a
reasonable time is to be used (determined at the time the loan is made) as a principal residence of the Participant. Interest shall be charged on loans to eligible Participants or Beneficiaries at a rate equal to two percentage points
(2%) above the rate paid by the United States government on treasury notes with the same maturity as the loan; provided, if the loan’s term exceeds five (5) years, the interest rate shall be the same as that charged by the bank
designated by the Committee on a fixed rate basis for a loan of similar size and maturity. All loans shall bear interest at a fixed rate. Such rate shall be determined as of the last business day of each month and shall apply to all loans advanced,
renewed or modified during the next month. Upon direction by the Plan Administrator, and subject to Subsection (c) below, the Trustees may foreclose upon such Participant’s interest in his Account in the event of default. A loan to a
Participant, when added to the outstanding balance of all other loans to the Participant from the Plan and other plans sponsored by the Employer, cannot exceed $50,000, reduced by the excess of the highest outstanding balance of loans from the Plan
(and all other plans sponsored by the Employer) during the one-year period ending on the day before the date the loan is made over the outstanding balance of the loans from the Plan on the date the loan is made. No distribution of a Benefit shall be
made to any Participant, Beneficiary or the estate of a Participant unless and until all unpaid loans made by the Plan to such Participant together with accrued interest have been paid in full or unless such unpaid loans have been offset against the
Participant’s Account. In determining if any of the foregoing limitations regarding the making of loans to Participants, loans made under all other plans (i) sponsored by the Employer and (ii) qualified under Sections 401(a) and
501(a) of the Code will be considered. All costs and expenses of any loan will be charged to the applicable Accounts of the Participant. 
 (b) Foreclosure of Loan Account. The Trustees may foreclose upon such Participant’s interest in his Account in the event of default under the loan made to the Participant under this Section. 
  

 VII-2 

 (c) Special Restrictions on Foreclosure. In the event of default under a loan made under this
Section, foreclosure under the promissory note evidencing such loan and attachment of the Participant’s interest in his applicable Accounts shall occur within a reasonable time following the event of default; provided, with respect to any
portion of a loan secured by amounts governed under Section 401(k) of the Code, if applicable, foreclosure on such 401(k) amounts shall not occur until the occurrence of an event described under Section 401(k) of the Code which would
otherwise permit a distribution to be made from the Plan. 
 (d) Spousal Consent Required. If benefits in the Plan are subject to the
Qualified Joint and Survivor rules, a Participant must obtain the consent of his spouse, if any, to use of the Account as security for the loan. Spousal consent shall be obtained no earlier than the beginning of the 90-day period that ends on the
date on which the loan is to be so secured. The consent must be in writing, must acknowledge the effect of the loan, and must be witnessed by a Plan representative or notary public. Such consent shall thereafter be binding with respect to the
consenting spouse or any subsequent spouse with respect to that loan. A new consent shall be required if the Account balance is used for renegotiation, extension, renewal, or other revision of the loan. If a valid spousal consent has been obtained
in accordance with this Subsection, then, notwithstanding any other provision of this Plan, the portion of the Participant’s Account 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 applicable Account balance payable at the time of death or distribution, but only if the reduction is used as repayment of the loan. If less than 100% of the Participant’s Account
(determined without regard to the preceding sentence) is payable to the surviving spouse, then the Account balance shall be adjusted by first reducing the applicable Account by the amount of the security used as repayment of the loan, and then
determining the Benefit payable to the surviving spouse. 
 (e) Establishment of Loan Program. The Committee is hereby authorized and
directed to establish a “loan program” (the “Loan Program”) in accordance with the rules and regulations promulgated by the Department of Labor and, the Trustees are further authorized to delegate to the Plan Administrator the
duties and responsibilities with regard to the implementation of the Loan Program as adopted by the Trustees for and on behalf of the Plan. The Loan Program shall, in accordance with Regulations promulgated by the Department of Labor, be considered
to be a part of this Plan for the purposes stated in the Loan Program. 
 (f) Suspension of Loan Repayments. Loan repayments may be
suspended under this Plan as permitted under Section 414(u) of the Code.

Section 8.4 Exercise of Power in Nondiscriminatory Manner. In exercising any discretionary or absolute authority under the terms of this Plan, the
Committee shall act in a consistent and nondiscriminatory manner treating all Participants in similar circumstances in a similar fashion.

after such hearing and shall notify the Claimant of its decision in the manner described above. If the Claimant has, not received written notice of the approval or denial of the Claim within the specified time, the Claim shall be deemed denied.

 All decisions shall be made in a nondiscriminatory manner. The decision of the Executive Committee shall be final and binding on all
persons affected. 
 Section 8.6 Indemnification. The Employer shall indemnify and hold harmless each member of the Committee from any and all
claims, loss, damages, expense and liability arising from any action or omission of any action of such member, provided such action or omission of action was in good faith and did not result from such member’s gross negligence or willful
misconduct. The Trust Fund may not be used for such indemnification. 
 Section 8.7 Investment Manager. The Committee, with the prior written
consent of the Employer, shall have the power to-appoint one or more Investment Managers, as defined in Section 3(38) of the Act, who shall have the power to manage, acquire, dispose of, and direct the investment of all or any portion of the
Trust Fund, and such other terms and conditions as the Committee or Trustee deems desirable. The Committee shall determine a reasonable compensation to be paid to the Investment Manager. Any such appointment shall be made by written instrument
naming the Investment Manager and specifying the portion of the Trust Fund which the Committee intends to place under the direction of the named Investment Manager. Such appointment shall become effective only upon the Committee’s receipt of
the written acknowledgement by the Investment Manager that it is a fiduciary of the Plan. Any Investment Manager so appointed shall be authorized to employ such agents as it may deem advisable in the discharge of its duties. 
 Section 8.8 Employment of Agents. The Committee is authorized to employ attorneys, accountants or any other agents as it deems advisable in the discharge of

no such address was filed, then at his last address as shown on the Employer’s records, shall be binding on the Participant or his Beneficiary for all purposes of the Plan. If the Committee furnishes notice to any Participant or Beneficiary
that he is entitled to a distribution pursuant to the Plan and the Participant or Beneficiary fails to claim such distribution or make his whereabouts known to the Committee within three (3) years thereafter, the share shall be disposed of as
follows: 
 (a) If a Participant is missing but the whereabouts of his Beneficiary is known to the Committee, the Committee shall direct the
Trustee to make payment to such Beneficiary; or 
  

 VIII-3 

 (b) If the whereabouts of such Participant and his Beneficiary is unknown to the Committee, the Committee
shall direct the Trustee to make the distribution of the Participant’s share or balance thereof to the Participant’s then surviving heirs-at-law as determined under the statutes and case law of Oklahoma which are in effect at that time as
if the Participant had died immediately upon the expiration of such three (3) year period. 
 Section 8.10 Appointment of Additional
Fiduciaries. The Plan Administrator may appoint one or more additional persons or entities to assist the Plan Administrator in carrying out its duties under the Plan. In addition to its ability to appoint an investment manager pursuant to
Section 8.9, the Plan Administrator shall be authorized to the extent permitted by the Act, designate an additional person or entity as a fiduciary (a “Designated Fiduciary”) with respect to aspects of the administration of the Plan
which must be set forth in a written agreement with such Designated Fiduciary. To the extent such person or entity is so designated pursuant to this Article VIII, neither the Company, the Plan Administrator or any other fiduciary of the Plan shall
be liable for the acts or omissions of such Designated Fiduciary. In addition, to the extent more than one person or entity is serving as the Plan Administrator, such Plan Administrators may allocate who shall be responsible for specific fiduciary
duties to carry out fiduciary responsibilities (other than Trustees responsibilities) under the Plan; provided, that any such allocations shall be reduced to writing, signed by the Plan Administrator or its designee, and filed with the Plan’s
permanent records. 
 Section 8.11 Payment of Plan Expenses. All reasonable expenses incurred in administering the Plan shall be paid by the
Trustees out of the principal or income of the Trust Fund; provided, however, that the Company in its discretion may pay any such expenses. In accordance with Revenue Ruling 2004-10, the Plan Administrator may charge reasonable Plan administrative
expenses on a pro rata basis, or on any other reasonable basis that complies with the requirements of the Act, to the Accounts of former Employees and their beneficiaries but not the accounts of current Employees. Any Employees shall not receive
compensation with respect to their services to the Plan. Without limiting the foregoing the Plan Administrator may direct the Trustee to reimburse the Company or another fiduciary for reasonable expenses incurred in administering the Plan.

 Section 8.12 Records and Reports. The Plan Administrator or its designee shall exercise such authority and responsibility as it deems
appropriate in order to comply with the Act and governmental regulations issued thereunder relating to records of the Participants’ Accounts and the percentage of the Participants’ Account which is vested and nonforfeitable under the Plan;
to notify Participants as required under the Act; to file the annual registration with the Internal Revenue Service; and, to file the annual reports with the Department of Labor.

 Section 8.13 Rules and Decisions. The Plan Administrator may adopt such rules as it deems necessary,
desirable, or appropriate. All rules and decisions of the Plan Administrator shall be uniformly and consistently applied to all Participants in similar circumstances. When making a determination or calculation, the Plan Administrator shall be
entitled to rely upon information furnished by a Participant or Beneficiary, the Employer, the legal counsel of the Employer or the Trustees.

 ARTICLE IX.

for this Plan and the Predecessor Plan shall be held, invested and administered in accordance with the terms of such Trust Agreement as the same may from time to time be amended. All contributions made by the Employer shall be paid into the Trust
Fund and all Benefits payable under the Plan shall be paid from the Trust Fund.

 ARTICLE X. 
 AMENDMENT AND TERMINATION 
 Section 10.1 Amendment of the Plan. The Company hopes and expects to continue
the Plan, but nevertheless reserves the right at any time to modify, amend or terminate the Plan. Pursuant to resolutions adopted by the Board of Directors of the Company (in accordance with the Company’s Bylaws and applicable corporate law),
the Plan may be wholly or partially amended, or otherwise modified, at any time by the execution of a written amendment to the Plan on behalf of the Company by the officer designated by the Company’s Board of Directors; provided, however, that
no such modification or amendment shall permit any part of the Trust Fund, other than such part as is required to be distributed in order to meet necessary expenses, to be used for, or diverted to, purposes other than for the exclusive benefit of
the Participants, their Beneficiaries, or their estates, and provided further that no such modification or amendment shall operate to reduce or eliminate the Accounts of any person or persons acquired prior to the effective date of such modification
or amendment (except as such modification or amendment shall be necessary in order to comply with any laws or regulations of the United States or of any state). 
 Section 10.2 Termination of the Plan. 
 (a) Complete Termination. In the event the Employer shall wholly
terminate the Plan, the Plan Administrator shall direct the Trustees to make an appraisal of the Trust Fund as of such termination date. The Trustees shall then deduct from the value of such appraisal an amount which they shall estimate to be
necessary to meet any expenses to be incurred during the termination period of the Trust. The Plan Administrator shall then require a valuation of all Accounts in the Trust Fund in accordance with Section 5.2 herein, as of such termination
date, based on the appraised value of the Trust Fund as adjusted after making provision for such expenses. Thereafter, any unallocated Employer contributions and Forfeitures existing on such termination date shall be allocated pursuant to Article IV
hereof among the eligible Participants who are employed on such termination date. The sum standing in the Accounts of each person after such recomputation and adjustment, if any, shall represent the final Benefit of each such person, and such amount
shall be 100% vested and shall be nonforfeitable, and no recomputation or other adjustment of any Account shall thereafter be made. The distribution by the Trustees shall be made promptly and, in any event, shall be completed within 12 months from
the date of termination of the Plan as follows: 
 (i) Each Participant or Beneficiary shall receive values equal to any amount being held in
such person’s Accounts as computed under the immediately preceding provisions of this Subsection 10.2(a). 
 (ii) With respect to the
remaining Trust Fund, if any, the interest of each Participant or Beneficiary shall be in the proportion that his Accounts bear to the total of all Accounts. 
 (b) Partial Termination. In the event of a partial termination of the Plan, the Plan Administrator shall direct the Trustees to make an appraisal of the Trust Fund as of such termination date. The Trustees
shall then deduct from the value of such appraisal an amount 

  

 X-1 

 
which they shall estimate to be necessary to meet any expenses to be incurred during the termination period of the Trust. The Plan Administrator shall then
require a valuation of all Accounts in the Trust Fund in accordance with Section 5.2 herein, as of such termination date, based on the appraised value of the Trust Fund as adjusted after making provision for such expenses. The sum standing in
the Accounts of each person, whose termination of employment resulted in the “partial termination” of the Plan, after such recomputation shall represent the final Benefit of each such person, and such amount shall be 100% vested and shall
be nonforfeitable, and no recomputation of any such Account shall thereafter be made. The distribution by the Trustees shall be made promptly and, in any event, shall be completed within 12 months from the date of partial termination of the Plan and
shall be made to each such person who shall receive values equal to any amount being held in such person’s Accounts as adjusted under the immediately preceding provisions of this Subsection 10.2(b). 
 (c) Termination Subject to Rules in Plan. In the event of any termination of the Plan, and distribution of Benefits are made from the Plan, all
such distributions will satisfy the rules for distribution as contained in Article VI hereof. 
 (d) Distribution Restrictions Under
Section 401(k) of the Code. If the Plan includes a Section 401(k) arrangement or if transferred assets described in Article XI herein are subject to the distribution restrictions of Sections 401(k)(2) and (10) of the Code, the
special distribution provisions of Article VI are subject to the restrictions of this Subsection. The portion of the Participant’s Benefit attributable to 401(k) Contributions and Special Employer Section 401(k) Contributions shall not be
distributable on account of Plan termination, as described in Article X herein, unless: (i) the Participant otherwise is entitled under the Plan to a distribution of that portion of his Benefit; or (ii) the Plan termination occurs without
the establishment of a successor plan. A successor plan under Subsection (b) is a defined contribution plan (other than an ESOP) maintained by the Employer (or by an Affiliated Employer) at the time of the termination of the Plan or within the
period ending 12 months after the final distribution of assets. A distribution made after March 31, 1988, pursuant to clause (ii), must be part of a lump sum distribution to the Participant of his Benefit. 
 Section 10.3 Power of Amendment Delegated. By adoption of this Plan, the Employer hereby expressly delegates to the Company the power to unilaterally amend
this Plan and related Trust hereto on behalf of such Employer.

 ARTICLE XI. 
 ROLLOVERS 
 Section 11.1 Requirements for Rollover by
Individuals. An Employee (whether or not a Participant under this Plan), who, as a result of a termination of another plan qualified under Section 401(a) of the Code, a termination of employment, disability or attainment of age 59 1/2 years, has had distributed to him his entire interest in a plan which meets the requirements of Section 401(a) of the Code
(hereinafter referred to as the “Other Plan”) may, in accordance with procedures approved by the Plan Administrator, transfer all or any part of the distribution received from the Other Plan to the Trustees under this Plan, provided the
following conditions are met: 
 (a) The transfer occurs on or before the 60th day following his receipt of the distribution from the
Other Plan, or, if such distribution had previously been deposited in an individual retirement account (as defined in Section 408 of the Code), the transfer occurs on or before the 60th day following his receipt of such distribution, plus
earnings thereon from such individual retirement account; 
 (b) The distribution from the Other Plan qualifies as a lump sum distribution
within the meaning of Subsection 402(e)(4)(A) of the Code or is a result of a termination of another plan qualified under Section 401(a) of the Code; and 
 (c) The amount transferred shall not exceed the distribution he received from the Other Plan, less the amount, if any, considered contributed by him in accordance with Subsection 402(e)(4)(D)(i) of the Code, plus
earnings thereon during the period, if any, in which the amount was held in an individual retirement account. 
 Section 11.2 Transfers From Another
Qualified Plan. 
 (a) With respect to an Employee (whether or not a Participant under this Plan), who has an undistributed Account
balance in another plan which meets the requirements of Section 401(a) of the Code (hereinafter referred to as the “Other Plan”), the Plan Administrator may, in its sole discretion, approve a direct transfer of such Account balance
(excluding After Tax Contributions) from the Other Plan to the Trustees under this Plan. 
 (b) If the Plan receives a direct transfer (by
merger or otherwise) of elective contributions (or amounts treated as elective contributions) under a plan with a Section 401(k) arrangement, the distribution restrictions of Sections 401(k)(2) and (10) of the Code continue to apply to
those transferred elective contributions. 
 Section 11.3 Procedures. With respect to transfers under either Section 11.1 or 11.2 herein,
the Plan Administrator shall develop such procedures, and may require such information from an Employee or the fiduciaries of the Other Plan desiring to make such a transfer, as it deems necessary or desirable to determine that the proposed transfer
will meet requirements of this Article XI and the law. Upon approval by the Plan Administrator, the amount transferred shall be deposited in the Trust Fund and shall be credited to a Rollover Account established in the Employee’s name. Such
Account shall be 100% vested in and nonforfeitable by the Employee, 

  

 XI-1 

 
shall share in increases and decreases thereon determined pursuant to Section 5.2 herein, but shall not share in Employer Contributions or Forfeitures.
Upon termination of employment, the total amount of Employee’s Rollover Account shall be distributed as part of his Benefit. 
 Section 11.4
Rollover to Another Plan or Traditional IRA. This Section applies to distributions made after December 31, 2001. 
 (a)
General. Notwithstanding any provision of the Plan to the contrary that would otherwise limit a Distributee’s election under this Section, a Distributee may elect, at the time and in the manner prescribed by the Plan Administrator, to
have any portion of an Eligible Rollover Distribution paid directly to an Eligible Retirement Plan specified by the Distributee in a Direct Rollover. The Plan Administrator shall establish procedures for implementing such Direct Rollover
distribution. 
 (b) Definitions. For purposes of this Section 11.4, the following definitions shall apply: 
 (i) “Eligible Rollover Distribution”: An “Eligible Rollover Distribution” is any distribution of all or any portion of the
balance to the credit of the Distributee, except that an Eligible Rollover Distribution does not include: any distribution that is one of a series of substantially equal periodic payments (not less frequently than annually) made for the life (or
life expectancy) of the Distributee or the joint lives (or joint life expectancies) of the Distributee and the Distributee’s designated Beneficiary, or for a specified period of 10 years or more; any distribution to the extent such distribution
is required under Section 401(a)(9) of the Code; the portion of any distribution that is not includable in gross income (determined without regard to the exclusion for net unrealized appreciation with respect to Employer Stock); and any
distribution attributable to a hardship. A portion of a distribution shall not fail to be an Eligible Rollover Distribution merely because the portion consists of After-Tax Employee Contributions which are not includible in gross income. However,
such portion may be transferred only to an individual retirement account or annuity described in Section 408(a) or (b) of the Code, or to a qualified defined contribution plan described in Section 401(a) or 403(a) of the Code that
agrees to separately account for amounts so transferred, including separately accounting for the portion of such distribution which is includible in gross income and the portion of such distribution which is not so includible. If any portion of an
eligible rollover distribution is attributable to payments or distributions from a designated Account holding Roth Contributions and earnings thereon, an Eligible Retirement Plan with respect to such portion shall include only another designated
account of the individual from whose account the payments or distributions were made holding Roth Contributions and earnings thereon, or a Roth IRA of such individual. 
 (ii) “Eligible Retirement Plan”: An “Eligible Retirement Plan” is an individual retirement account described in Section 408(a) of the Code, an individual retirement annuity described in
Section 408(b) of the Code, an annuity plan described in Section 403(a) of the Code, or a qualified trust described in Section 401(a) of the Code, that accepts the Distributee’s Eligible Rollover Distribution. However, in the
case of an Eligible Rollover Distribution to the surviving spouse, an Eligible Retirement Plan is an individual retirement account or individual retirement annuity. Effective for distributions made after December 31, 

  

 XI-2 

 
2001, an eligible retirement plan shall also mean an annuity contract described in Section 403(b) of the Code and an eligible plan under
Section 457(b) of the Code which is maintained by a state, 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 this Plan. The definition of Eligible Retirement Plan shall also apply 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 relation order, as
defined in Section 414(p) of the Code. If any portion of an eligible rollover distribution is attributable to payments or distributions from a designated Roth account, an eligible retirement plan with respect to such portion shall include only
another designated Roth account of the individual from whose account the payments or distributions were made, or a Roth IRA of such individual. 
 (iii) “Distributee”: A “Distributee” includes a Participant or former Participant. In addition, the Participant’s spouse or former Participant’s surviving spouse and the Participant’s or former
Participant’s spouse or former spouse who is the alternate payee under a qualified domestic relations order, as defined in Section 414(p) of the Code, are distributees with regard to the interest of the spouse or former spouse. 

(iv) “Direct Rollover”: A “Direct Rollover” is a payment by the Plan directly to the Eligible Retirement Plan specified by
the Distributee. 
 Section 11.5 Sole Interest in Plan. Upon a transfer of an account from an Other Plan as aforesaid, the Employee’s
Rollover Account shall represent his sole interest in the Plan until he becomes a Participant. 
 Section 11.6 Rollovers or Transfers of Certain
Persons Prohibited. In no event shall a rollover under Section 11.1 herein or a transfer under Section 11.2 herein be made to this Plan with respect to an account of an “owner-employee” as defined under Section 401(c) of
the Code. 
 Section 11.7 Joint and Survivor Annuity. With respect to any portion of a Rollover Account attributable to a direct transfer as
described in Section 11.2 above representing funds related to a defined benefit plan, money purchase pension plan (including a target benefit pension plan), stock bonus plan or profit sharing plan which provided a life annuity form of payment
to the Participant immediately prior to the rollover to this Plan, the following special provisions shall apply only with respect to such funds payable to a married Participant upon his termination of employment or death, as the case may be.

 (a) Automatic Qualified Joint and Survivor Annuity. Unless an optional form of benefit is selected pursuant to a Qualified Election
within the Election Period, a Participant’s benefit shall be paid in the form of a Qualified Joint and Survivor Annuity, provided, such Spouse can elect any other optional form of payment under this Plan. 
 (b) Automatic Qualified Preretirement Survivor Annuity. Unless an optional form of benefit has been selected within the Election Period pursuant
to a qualified election, if a Participant dies before payment of benefits have commenced, then the Participant’s benefit shall be applied toward the purchase of an annuity for the life of the surviving Spouse; provided, such Spouse can elect
any other optional form of payment under this Plan. 
  

 XI-3 

 (c) Definitions. 
 (i) Annuity Starting Date: The words “Annuity Starting Date” shall mean the date payment of Benefits would commence. The Annuity Starting Date for a distribution in a form other than a Qualified Joint
and Survivor Annuity may be less than 30 days after receipt of the Annuity Election Notice provided: (a) the Participant has been provided with information that clearly indicates that he has at least 30 days to consider whether to waive the
Qualified Joint and Survivor Annuity and elect (with spousal consent) to a form of distribution other than a Qualified Joint and Survivor Annuity; (b) the Participant is permitted to revoke any affirmative distribution election at least until
the Annuity Starting Date or, if later, at any time prior to the expiration of the 7-day period that begins the day after the Annuity Election Notice is provided to the Participant; and (c) the Annuity Starting Date is a date after the date the
Annuity Election Notice was provided to the Participant. 
 (ii) Election Notice: The words “Election Notice” shall mean

 XIII-1Three-Year Credit Agreement

 Exhibit 10.11 
 

    Credit Agreement  
 This agreement dated as of May 1, 2008 is between JPMorgan Chase
Bank, N.A. (together with its successors and assigns, the “Bank”), whose address is 707 Travis, 7th Floor, Houston, TX 77002, and O.I. Corporation (individually, the “Borrower” and if more than one, collectively,
the “Borrowers”), whose address is 151 Graham Road, College Station, TX 77842. 
  

	1.	Credit Facilities. 

  

	 	1.1	Scope. This agreement governs Facility A, and, unless otherwise agreed to in writing by the Bank and the Borrower or prohibited by any Legal Requirement (as hereafter
defined), governs the Credit Facilities as defined below. Advances under any Credit Facilities shall be subject to the procedures established from time to time by the Bank. Any procedures agreed to by the Bank with respect to obtaining advances,
including automatic loan sweeps, shall not vary the terms or conditions of this agreement or the other Related Documents regarding the Credit Facilities. 

  

	 	1.2	Facility A (Line of Credit). The Bank has approved a credit facility to the Borrower in the principal sum not to exceed $6,000,000.00 in the aggregate at any one time
outstanding (“Facility A”). Facility A shall be used only for the purpose of (a) acquisition financing (“Acquisition Advances”), and (b) working capital for Borrower’s regular business operations.
Borrower shall provide advice to Bank of the purpose of each advance made under Facility A in form and substance reasonably satisfactory to Bank, and in the form of Exhibit A if Bank shall request. 

 A. Required Paydown and Reduction in Facility A after Acquisition Advances. If
(i) Borrower shall have requested and received Acquisition Advances with an aggregate amount of $1,000,000.00 or more, and (ii) the Line of Credit Note shall have had an aggregate principal balance continuously exceeding $3,000,000.00 for
more than 90 days (the 90th day being a “Reduction Trigger Date”), then on the 180th day after both such conditions first shall have occurred (a “Required Reduction Date”), the maximum face amount of Facility A shall be reduced by an amount equal to the
total principal balance outstanding on the Required Reduction Date. To the extent the outstanding principal balance of the Line of Credit Note shall exceed maximum face amount of Facility A as so reduced on the Required Reduction Date, Borrower
shall make a repayment of principal on the Required Reduction Date so as to comply with the reduction in face amount of Facility A. After the occurrence of any Required Reduction Date, if the conditions described in the first sentence shall again
occur, there will be another Reduction Trigger Date and Required Reduction Date and the foregoing provisions concerning them shall be applicable. 
 B. Borrowing Base. The aggregate principal amount of advances outstanding at any one time under Facility A (the “Aggregate Outstanding Amount”) shall not exceed the Borrowing Base or the maximum principal amount then
available under Facility A, whichever is less (the “Maximum Available Amount”). If at any time the Aggregate Outstanding Amount exceeds the Maximum Available Amount, the Borrower shall immediately pay the Bank an amount equal to
such excess. “Borrowing Base” means the aggregate of: 
 1. 85% of the book value of all Eligible Accounts; plus 

2. 40% of the lower of cost (determined using the first-in, first-out method of inventory accounting) or wholesale market value, as determined by the
Bank, of all Eligible Inventory 
  

 C. Covenant to Provide Additional Security. In the event that total combined outstanding balance
of all Notes under Facility A shall in the aggregate continuously exceed $4,000,000.00 for more than 90 days, Borrower shall promptly upon notice by Bank provide to Bank a first priority perfected security interest in all of its Equipment (as
defined in the Uniform Commercial Code) excluding any Equipment subject to lien disclosed to Bank prior to the date of this agreement, on terms and conditions and otherwise acceptable to Bank in form and substance.

(e) exercise any and all other rights pursuant to any of the Related Documents, at law, in equity or otherwise. 

 A.
Cure Periods. Notwithstanding anything to the contrary contained in this agreement or any of the other Related Documents, the Bank shall not exercise its option to accelerate the maturity of the Notes upon the occurrence of (i) a default in
payment of money included in the Liabilities, unless the default has not been fully cured within five (5) days after its occurrence, or (ii) a default in timely delivery of any report of financial information provided for in

by advance, disbursement of a loan, issuance of a letter of credit or otherwise after the occurrence of any default or event which with the giving of notice or the passage of time or both could become a default or during any cure period. The
inclusion of any cure period in this agreement shall have no bearing on the due dates for payments under any of the Related Documents, whether for purposes of calculating late payment charges or otherwise. 
 B. Remedies Generally. The rights of the Bank under this agreement and the other Related Documents are in addition to other rights (including
without limitation, other rights of setoff) the Bank may have contractually, by law, in equity or otherwise, all of which are cumulative and hereby retained by the Bank. Each Obligor agrees to stand still with regard to the Bank’s enforcement
of its rights, including taking no action to delay, impede or otherwise interfere with the Bank’s rights to realize on any Collateral. 
 C. Bank’s Right of Setoff. The Borrower grants to the Bank a security interest in the Deposits, and the Bank is authorized to setoff and apply, all Deposits, Securities and Other Property, and Bank Debt against any and all
Liabilities. This right of setoff may be exercised at any time from time to time after the occurrence of any default, without prior notice to or demand on the Borrower and regardless of whether any Liabilities are contingent, unmatured or
unliquidated. In this paragraph: (a) the term “Deposits” means any and all accounts and deposits of the Borrower (whether general, special, time, demand, provisional or final) at any time held by the Bank (including all
Deposits held jointly with another, but excluding any IRA or Keogh Deposits, or any trust Deposits in which a security interest would be prohibited by any Legal Requirement); (b) the term “Securities and Other Property” means
any and all securities and other personal Property of the Borrower in the custody, possession or control of the Bank, JPMorgan Chase & Co. or their respective Subsidiaries and Affiliates (other than Property held by the Bank in a fiduciary
capacity); and (c) the term “Bank Debt” means all indebtedness at any time owing by the Bank, to or for the credit or account of the Borrower and any claim of the Borrower (whether individual, joint and several or otherwise)

	 	8.1	Notice. Any notices and demands under or related to this agreement shall be in writing and delivered to the intended party at its address stated in this agreement, and if to

purposes of the receipt of notices and demands by giving notice of the change in the manner provided in this provision. 

  

	 	8.2	No Waiver. No delay on the part of the Bank in the exercise of any right or remedy waives that right or remedy. No single or partial exercise by the Bank of any right or
remedy precludes any other future exercise of it or the exercise of any other right or remedy. The making of an advance during the existence of any default or subsequent to the occurrence of a default or when all conditions precedent have not been
met shall not constitute a waiver of the default or condition precedent. No waiver or indulgence by the Bank of any default is effective unless it is in writing and signed by the Bank, nor shall a waiver on one occasion bar or waive that right on
any future occasion. 

  

	 	8.3	Integration. This agreement, the Notes, and the other Related Documents embody the entire agreement and understanding between the Borrower and the Bank and supersede all
prior agreements and understandings relating to their subject matter. If any one or more of the obligations of the Borrower under this agreement or the Notes is invalid, illegal or unenforceable in any jurisdiction, the validity, legality and
enforceability of the remaining obligations of the Borrower shall not in any way be affected or impaired, and the invalidity, illegality or unenforceability in one jurisdiction shall not affect the validity, legality or enforceability of the
obligations of the Borrower under this agreement, the Notes and the other Related Documents in any other jurisdiction.

The Borrower agrees that any legal action or proceeding with respect to any of its obligations under this agreement may be brought by the Bank in any state or federal court located in the State of Texas, as the Bank in its sole discretion may elect.
By the execution and delivery of this agreement, the Borrower submits to and accepts, for itself and in respect of its property, generally and unconditionally, the non-exclusive jurisdiction of those courts. The Borrower waives any claim that the
State of Texas is not a convenient forum or the proper venue for any such suit, action or proceeding. 

  

	 	8.6	Survival of Representations and Warranties. The Borrower understands and agrees that in extending the Credit Facilities, the Bank is relying on all representations,
warranties, and covenants made by the Borrower in this agreement or in any certificate or other instrument delivered by the Borrower to the Bank under this agreement or in any of the other Related Documents. The Borrower further agrees that
regardless of any investigation made by the Bank, all such representations, warranties and covenants will survive the making of the Credit Facilities and delivery to the Bank of this agreement, shall be continuing in nature, and shall remain in full
force and effect until such time as the Liabilities shall be paid in full. 

  

	 	8.7	Non-Liability of the Bank. The relationship between the Borrower on one hand and the Bank on the other hand shall be solely that of borrower and lender. The Bank shall have
no fiduciary responsibilities to the Borrower. The Bank undertakes no responsibility to the Borrower to review or inform the Borrower of any matter in connection with any phase of the Borrower’s business or operations. 

 

	 	8.8	Indemnification of the Bank. The Borrower agrees to indemnify, defend and hold the Bank, its parent companies, Subsidiaries, Affiliates, their respective successors and

claim, deficiency, expense, interest, penalties, attorneys’ fees (including the fees and expenses of any attorneys engaged by the Indemnified Person) and amounts paid in settlement (“Claims”) to which any Indemnified Person may
become subject arising out of or relating to the Credit Facilities, the Liabilities under this agreement or any other Related Documents or the Collateral, including any Claims resulting from any Indemnified Person’s own negligence,
except to the limited extent that the Claims are proximately caused by the Indemnified Person’s gross negligence or willful misconduct. The indemnification provided for in this paragraph shall survive the termination of this agreement and shall
not be affected by the presence, absence or amount of or the payment or nonpayment of any claim under, any insurance. 

  

	 	8.9	Counterparts. This agreement may be executed in multiple counterparts, each of which, when so executed, shall be deemed an original, but all such counterparts, taken
together, shall constitute one and the same agreement. 

  

	 	8.10	Advice of Counsel. The Borrower acknowledges that it has been advised by counsel, or had the opportunity to be advised by counsel, in the negotiation, execution and delivery
of this agreement and any other Related Documents.

waiver of this agreement and/or any Related Document(s), the making, servicing and collection of the Credit Facilities and the realization on any Collateral and any other amounts owed under the Related Documents, including without limitation

reorganization, insolvency or other similar proceeding involving any Obligor, Pledgor, or Property of any Obligor, Pledgor, or Collateral. The obligations of the Borrower under this section shall survive the termination of this agreement.
Provided however, notwithstanding the foregoing, the initial preparation of this agreement and the Related Documents presented in connection therewith, each in Bank’s standard form, shall be without charge to Borrower.

  

	 	8.12	 Reinstatement. The Borrower agrees that to the extent any payment or transfer is received by the Bank in connection with the Liabilities, and all or any part
of the payment or transfer is subsequently invalidated, declared to be fraudulent or preferential, set aside or required to be repaid or transferred by the Bank or paid or transferred over to a trustee, receiver or any other entity, whether under
any proceeding or otherwise (any of those payments or transfers is hereinafter referred to as a “Preferential Payment”), then this agreement and the Notes shall continue to be effective or shall be reinstated, as the case may be,
even if all those Liabilities have been paid in full and whether or not the Bank is 

	 	 
in possession of the Notes and whether any of the Notes has been marked, paid, released or cancelled, or returned to the Borrower and, to the extent of the
payment, repayment or other transfer by the Bank, the Liabilities or part intended to be satisfied by the Preferential Payment shall be revived and continued in full force and effect as if the Preferential Payment had not been made. The obligations
of the Borrower under this section shall survive the termination of this agreement.

other Related Documents to JPMorgan Chase & Co., or any of its Subsidiaries or Affiliates or their successors, or to any one or more purchasers or potential purchasers of the Notes or the Related Documents. The Borrower agrees that the Bank
may at any time sell, assign or transfer one or more interests or participations in all or any part of its rights and obligations in the Notes to one or more purchasers whether or not related to the Bank. 

  

	 	8.14	Waivers. Each Obligor waives (a) any right to receive notice of the following matters before the Bank enforces any of its rights: (i) any demand, diligence,

from any cause whatsoever (other than payment in full) of the obligation of the Borrower for the Liabilities; and (f) any defense based on or arising out of any defense that the Borrower may have to the payment or performance of the Liabilities
or any portion thereof. Each Obligor consents to any extension or postponement of time of its payment without limit as to the number or period, to any substitution, exchange or release of all or any part of any Collateral, to the addition of any
other party, and to the release or discharge of, or suspension of any rights and remedies against, any Obligor. The Bank may waive or delay enforcing any of its rights without losing them. Any waiver affects only the specific terms and time period
stated in the waiver. No modification or waiver of any provision of the Notes is effective unless it is in writing and signed by the Person against whom it is being enforced. To the extent not prohibited by any Legal Requirement, each Obligor waives

information that is available to the Bank on a nonconfidential basis prior to disclosure by the Borrower; provided that, in the case of information received from the Borrower after the date hereof, such information is clearly identified at the time
of delivery as confidential. Any person required to maintain the confidentiality of Information as provided in this Section shall be considered to have complied with its obligation to do so if such person has exercised the same degree of care to
maintain the confidentiality of such Information as such person would accord to its own confidential information. If any portion of the Confidential Information is required to be disclosed by Bank pursuant to judicial action, governmental
regulations, or other legal requirements other than to a regulatory agency with supervisory authority over the Bank or any of its affiliates, then to the extent permitted by law, the Bank will promptly (and if reasonably possible before any
such disclosure is required) inform Borrower of the existence, terms, and circumstances surrounding such request. Bank will reasonably cooperate with Borrower in Borrower’s efforts to protect the Confidential Information as Borrower may
request, and Bank shall be entitled to advance payment and/or advance assurance of reimbursement of any costs and expenses (including costs of counsel) to Bank associated with such cooperation. If, in the absence of a protective order, Bank is
compelled as a matter of law to disclose any Confidential Information, it may disclose only that portion of the Confidential Information as Bank reasonably believes is required by law to be disclosed and will use reasonable efforts to obtain
confidential treatment for the information. 

  

	9.	USA PATRIOT ACT NOTIFICATION. The following notification is provided to the Borrower pursuant to Section 326 of the USA Patriot Act of 2001, 31 U.S.C. Section 5318:

 IMPORTANT INFORMATION ABOUT PROCEDURES FOR OPENING A NEW ACCOUNT. To help the government fight the funding of terrorism and
money laundering activities, Federal law requires all financial institutions to obtain, verify, and record information that identifies each Person that opens an account, including any deposit account, treasury management account, loan, other
extension of credit, or other financial services product. What this means for the Borrower: When the Borrower opens an account, if it is an individual the Bank will ask for its name, taxpayer identification number, residential address, date of
birth, and other information that will allow the Bank to identify it, and, if it is not an individual the Bank will ask for its name, taxpayer identification number, business address, and other information that will allow the Bank to identify it.
The Bank may also ask, if the Borrower is an individual, to see its driver’s license or other identifying documents, and if it is not an individual, to see its Organizational Documents or other identifying documents.

ACTION OR PROCEEDING ANY SPECIAL, EXEMPLARY, PUNITIVE OR CONSEQUENTIAL DAMAGES.  

  

	11.	JURY WAIVER. THE BORROWER AND THE BANK HEREBY VOLUNTARILY, KNOWINGLY, IRREVOCABLY AND UNCONDITIONALLY WAIVE ANY RIGHT TO HAVE A JURY PARTICIPATE IN RESOLVING ANY DISPUTE
(WHETHER BASED ON CONTRACT, TORT, OR OTHERWISE) BETWEEN THE BORROWER AND THE BANK ARISING OUT OF OR IN ANY WAY RELATED TO THIS AGREEMENT. THIS PROVISION IS A MATERIAL INDUCEMENT TO THE BANK TO PROVIDE THE FINANCING DESCRIBED HEREIN.
