 INTRODUCTION 

The Board of Directors of National Fuel Gas Company authorized the adoption of the National Fuel Gas Company
Tax-Deferred Savings Plan for Non-Union Employees having an original effective date of July 1, 1984. The Plan has been amended from time to time thereafter. The
Board now wishes to amend and restate the terms of the Plan, continuing the Plan for the benefit of eligible employees of National Fuel Gas Company and its related companies, with such amendment and restatement generally effective as of
January 1, 2016, except as otherwise hereinafter provided. 
 The funds to provide benefits under this Plan have been and will continue
to be held, managed, invested and disbursed in accordance with the terms of this Plan and the separate Trust Agreement established as the funding vehicle under the Plan. This Plan document, together with the separate Trust Agreement, are designed to
constitute a qualified plan under Section 401 and Section 501 of the Internal Revenue Code of 1986, as amended. 
 Thus, National
Fuel Gas Company hereby amends and restates the Plan as follows: 












 ARTICLE 1

effective date of this restatement is January 1, 2016, except as otherwise provided in this document. 

Section 1.3    Basic Definitions. 

(a)    Affiliated Corporation means any corporation that is a member of a controlled group of
corporations, as defined in Section 414(b) of the Code, that includes the Company. 

(b)    Affiliated Service Organization means any service organization that is a member of an
affiliated service group, as defined in Section 414(m) of the Code, that includes the Company.

 (i)    Eligible Employee means, except as otherwise provided, any Employee of the Company who is
customarily employed in the United States, except: 
 (1)    Employees Covered by Collective
Bargaining Agreement. Employees included in a unit of Employees covered by an agreement that the Secretary of Labor finds to be a collective bargaining agreement between the Company and Employee representatives (within the meaning of
Section 7701(a)(46) of the Code) if there is evidence that retirement benefits were the subject of good faith bargaining and the terms of the collective bargaining agreement do not specifically provide for participation in the Plan.

 (2)    Nonresident Aliens. Employees who
are nonresident aliens (within the meaning of Section 7701(b)(1)(B) of the Code) who received no earned income (within the meaning of Section 911(d)(2) of the Code) from the Company that constitutes income from sources within the United

(3)    Contingent Workers. Any individual who is a worker:

treats as an independent contractor; or 
 (iii)    who the Company does not treat as its Employee and
who performs services for the Company pursuant to an agreement between the Company and another person. 
 The purpose of this
provision is to exclude from participation in the Plan all persons who may actually be Employees, but who are not paid as though they are Employees, regardless of the reason they are excluded from the Company’s payroll, and regardless of
whether that classification is correct. 
 If the Company reclassifies an individual as an Employee, he or she may be an
Eligible Employee prospectively from the effective date of the reclassification only, and then only if he or she otherwise satisfies the requirements of this Plan. 

If an individual not classified by the Company as an Employee is retroactively reclassified as an Employee by any governmental
or regulatory authority, the individual will nonetheless be deemed to have become an Eligible Employee only prospectively on the event of the reclassification (and not retroactively to the date on which he or she was found to have first
become an Employee for any other purpose), and then only if he or she otherwise satisfies the requirements of the Plan.

 (j)    Employee means any common law employee of the Company. 

(k)    Entry/Adjustment Date means any date established by the Committee in advance of any Plan Year on
which a Participant either may enter the Plan or change his or her contribution percentage. Notwithstanding the preceding sentence and solely for purposes of Section 3.1, in the case of a Participant whose Base Salary is reduced during the
course of a Plan Year as a result of the Participant electing unpaid leave under the Family & Medical Leave Act of 1993, as a result of a workers compensation benefit or as a result of the enforcement of the Company’s sick pay policy,
as it may be in effect from time to time, the Committee may declare that an additional Entry/Adjustment Date will have occurred for such Participant as of the date such Participant’s Base Salary is reduced. The intent of this provision is to

statement establishing that the absence was due to one or more of the reasons enumerated in this paragraph and the number of days the Employee was absent. The Employee’s statement must be filed with the Committee on forms provided by it. 

Hours of Service will be determined on the basis of actual hours credited. 

Notwithstanding the foregoing, if the Committee does not maintain records accounting for actual Hours of Service performed by an Employee, the
Employee will be credited with 45 Hours of Service for each week the Employee would be credited with at least 1 Hour of Service during the week. 

An Employee will be credited with 45 Hours of Service for each week he is on unpaid leave of absence for less than 12 months and for each week

Such period begins on the date the Employee retires, quits or is discharged, or if earlier, the 12-month anniversary of the date on which the Employee was otherwise first absent from service. In the case of an individual who is absent from work for maternity or paternity reasons, the 12-consecutive month period beginning on the first anniversary of the first date of such absence shall not constitute a One-Year Break in Service. For purposes of this
paragraph, an absence from work for maternity or paternity reasons means an absence (1) by reason of the pregnancy of the individual, (2) by reason of the birth of a child of the individual, (3) by reason of the placement of a child
with the individual in connection with the adoption of such child by such individual, or (4) for purposes of caring for such child for a period beginning immediately following such birth or placement.

provided, however, that for a Post-2003 Participant who meets the conditions in Section 1.3(ii)(c), Years of Company Contribution Service includes service performed as such a Post-2003 Participant before July 1, 2003. Except for a
Post-2003 Participant who meets the conditions in Section 1.3(ii)(c), the 12-consecutive month period will be measured from the later of the Employee’s Date of Hire or commencement of employment in a
classification set forth in Section 1.3(ii)(a) through 1.3(ii)(h), and anniversaries thereof. Notwithstanding the foregoing, for Supervisory Employees of Highland Forest Resources, Inc., the
12-consecutive month period described in the preceding sentence commences on the later of the Employee’s Date of Hire or the date on which the Employee becomes a Supervisory Employee. 

Section 1.4    Rights of Former Employees and Obligations of the Company. Except
as otherwise provided in the Plan, the rights of Employees covered under the Plan who retired or otherwise separated from the service of the Company before the effective date of this restated Plan and the obligations of the Company on any date
before the effective date of this restated Plan are governed by the terms of the Plan in effect on that date. On and after the effective date of this restatement, the rights of Employees who retire or otherwise separate from the service of the
Company and the obligations of the Company are governed by this restated Plan, together with any amendments to the Plan. 

Section 1.5    Transfers of Accounts From Thrift Plan. Certain amounts credited to a
Participant’s accounts under the Thrift Plan are transferred to this Plan as of August 1, 2003. Amounts transferred from the Thrift Plan are allocated to the Participant’s Thrift Account.

 ARTICLE 2 

ELIGIBILITY FOR PARTICIPATION 

Section 2.1     Age and Service Requirements. Each Eligible Employee who was a

later of (a) his or her completion of one Year of Participation Service, and (b) his or her attainment of age 18. 
 Each Eligible
Employee who completes the service requirement in (a), but who has a Severance from Employment before the Entry/Adjustment Date will immediately become a Participant when he or she returns to the service of the Company unless the Eligible Employee,
when he or she returns to the service of the Company, has not yet satisfied the age requirement in (b). Notwithstanding the preceding sentence, an Eligible Employee will not commence participation in the Plan before the Entry/Adjustment Date that
otherwise would have applied had the Participant not had a Severance from Employment. 
 Notwithstanding the foregoing, an Eligible Employee
who would otherwise meet the requirements in (a), except that the Eligible Employee has not completed at least One Year of Participation Service, may, on the first day of the first payroll period that begins on the later of (i) February 1,
2014, or (ii) the first day of the month coincident with or next following three continuous months of full-time employment with the Company measured from the Eligible Employee’s Date of Hire, make Salary Reduction Contributions under
Section 3.1 and receive Matching Contributions under Section 3.3 and will be treated as a “Participant” for purposes of Sections 3.1 and 3.3. 

Notwithstanding the foregoing, an Eligible Employee who is a Post-2003 Participant will be treated as a “Participant” for purposes
of Section 3.2. 
 Notwithstanding any other provision of this Article, in the case of an Eligible Employee who was employed by
Whittier Trust Company on March 31, 1998, and became an employee of Seneca Resources Corporation on April 1, 1998, the Eligible Employee will not be required to satisfy the eligibility service requirement described above and will be eligible to
commence participation on the first day of the first payroll period that begins after April 1, 1998.

first payroll period that begins on January 1, 1999. This waiver of the 

  
 - 14 - 













 
eligibility service requirements will not apply to any Eligible Employee who is hired by or commences employment with Highland Forest Resources, Inc. (formerly, Highland Land and Minerals,
Inc.) after January 1, 1999. 
 Section 2.2    Change in Employment Status. 

(a)    Employee Becomes Eligible Employee. If an Employee’s status changes so that he or she becomes an
Eligible Employee, he or she will become a Participant on the later of the first Entry/Adjustment Date coincident with or following his or her satisfaction of the age and service requirements in Section 2.1 or the first day of the first payroll
period that begins on or after the date of the change in status. 
 Notwithstanding the foregoing, an individual who is an Eligible Employee
and who previously was a member of the National Fuel Gas Company Tax-Deferred Savings Plan (the “Union Plan”), but who ceased to be a member of the Union Plan because of a change in employment
classification, will become eligible to participate in the Plan immediately after his or her change of employment status. 

(b)    Participant Becomes a Non-Eligible Employee. If a
Participant’s employment status changes so that he or she is no longer an Eligible Employee, the Participant is not entitled to make any Salary Reduction Contributions or receive Company Contributions or Matching Contributions with respect to
any compensation earned while he or she is not an Eligible Employee. 

Section 2.3    Termination and Resumption of Participation. 

(a)    Termination of Participation. Except as otherwise provided by this Section, an Eligible Employee who
is a Participant will remain a Participant until the date his or her entire nonforfeitable interest is paid to him or her or to his or her Beneficiary, or the date he or she dies, if earlier. 

(b)    Inactive Participant. If a Participant has a Severance from Employment, he or she is an Inactive
Participant for the Plan Year in which the Severance from Employment occurs and for each subsequent Plan Year that he or she continues to have a Severance from Employment. 

(c)    Resumption of Participation. An Inactive Participant is not entitled to make Salary Reduction
Contributions or receive Company Contributions or Matching Contributions under Article 3. However, an Inactive Participant will resume active participation and be entitled to make Salary Reduction Contributions and receive Company Contributions and
Matching Contributions in accordance with Article 3 immediately upon his or her reemployment by the Company as an Eligible Employee. 

Section 2.4    Service with and Transfers from Organizations Under Common Control. 

(a)    Service with Organizations Under Common Control. Except as otherwise provided in the Plan, Hours of
Service completed by an Employee with an

Organization Under Common Control are credited for purposes of this Article. Hours of Service     are also credited to any Employee considered an Employee of any Organization
Under Common Control. 
 (b)    Transfers of Employment. If an Employee transfers employment from
the Company to an Organization Under Common Control, the transfer will not be considered a Severance from Employment under the Plan, and the Employee will continue to be credited with Hours of Service as provided in Subsection (a).

 ARTICLE 3 

CONTRIBUTIONS 

Section 3.1    Salary Reduction Contributions. 

(a)    In General. Effective August 1, 2002 and thereafter, each Participant, in accordance with
Subsection (b) may elect to contribute a percentage amount, expressed in one percent increments, equal to at least 2% of “Base Salary” and not to exceed 50% of “Base Salary”, as defined in Section 3.8. Effective
February 1, 2016, each Participant, in accordance with Subsection (b) may elect to contribute a percentage amount, expressed in one percent increments, equal to at least 2% of “Base Salary” and not to exceed 60% of “Base
Salary”, as defined in Section 3.8. 
 For the purposes of the Plan, “Salary Reduction Contribution” means a
contribution made pursuant to a Participant’s election under this Subsection. Salary Reduction Contributions under this Subsection will be made by reducing a Participant’s Base Salary throughout the period during which his or her election
under this Section remains in effect. The amount of each Participant’s Salary Reduction Contributions will be recalculated as of each Entry/Adjustment Date, based on the Participant’s then current Base Salary. 

All Salary Reduction Contributions are intended to qualify as “employer contributions” under Section 401(k) of the Code. 

Effective as of July 1, 2005, individuals who are employed as “Customer Support Representative I” or “Customer Support
Representative II” are not eligible to make Salary Reduction Contributions. 
 (b)    Salary Reduction
Contribution Elections. The Committee may prescribe uniform rules of general application concerning all elections under this Section, including the effective date of any elections, or changes to elections, made by Participants under this
Section. The rules also may limit the amount of Salary Reduction Contributions or the frequency of any changes to elections made by Participants. All elections under this Section will remain in effect until modified or discontinued by the
Participant in accordance with the rules established by the Committee. 
 For a Participant who becomes an Eligible Employee in connection
with a change in employment which results in such Employee ceasing to participate in the Union Plan (as defined in Section 2.2(a)), such Employee’s contribution election then in effect under the Union Plan (if any) will continue to be
applicable on the same terms as then in effect, until the next Entry/Adjustment Date, but such contributions will be made to this Plan following such change in employment. 

For Participants whose classification as an Eligible Employee changes, for example, changing from being Group I Employees to Group II
Employees, the respective contribution elections then in effect (if any) will continue to be applicable on the same terms as then in effect, until the next Entry/Adjustment Date. 

  
 - 17 - 













 The Committee must provide a reasonable period at least once each calendar year for a
Participant to commence Salary Reduction Contributions or to modify the amount of his or her Salary Reduction Contributions. Furthermore, Participants, before any payroll period or other payment of Base Salary, may elect to discontinue Salary
Reduction Contributions. A discontinuance of Salary Reduction Contributions will remain in effect until a new election is made in accordance with the provisions of this Subsection. A Participant may not make retroactive elections under this Section.

 (c)    402(g) Limit. A Participant’s Salary Reduction Contributions, together with the
Participant’s other elective deferrals (as defined in Section 402(g)(3) of the Code), may not exceed the dollar limitation or applicable dollar amount of Section 402(g)(1) of the Code, as adjusted by Section 402(g)(5) of the
Code, during any calendar year, except to the extent permitted under Section 3.1(d) and Section 414(v) of the Code, if applicable. If this limit is exceeded, the Committee will direct the Trustees to distribute the excess amount in
accordance with Section 3.14. 
 (d)    Catch-Up
Contributions. All Participants who have attained age 50 before the close of the Plan Year will be eligible to make catch-up contributions in accordance with and subject to the limitations of
Section 414(v) of the Code. Such catch-up contributions will not be taken into account for purposes of the provisions of the Plan implementing the required limitations of Sections 402(g) and 415 of the
Code. The Plan will not be treated as failing to satisfy the provisions of the Plan implementing the requirements of Sections 401(k)(11), 401(k)(12), 410(b), or 416 of the Code, as applicable, by reason of making of such catch-up contributions. This Section shall apply to contributions made after February 1, 2003. 

Section 3.2    Company Contribution. 

(a)     For each calendar month commencing with the February 1, 2014 Entry/Adjustment Date, the Company Contribution
to the Plan will be as follows: 3% of the Company Contribution Compensation for that month for each Post-2003 Qualified Participant who has been credited with fewer than six Years of Company Contribution Service as of the most recent
Entry/Adjustment Date; and 4% of the Company Contribution Compensation for that month for each Post-2003 Qualified Participant who has been credited with at least six Years of Company Contribution Service as of the most recent Entry/Adjustment Date.

 (b)    For purposes of this Section and Section 3.7(d), Company Contribution Compensation for a month is
the sum of: 1112 of a Post-2003 Participant’s regular base compensation (salary or hourly pay) as of the most recent Entry/Adjustment Date. Notwithstanding the preceding sentence, Company Contribution Compensation will specifically include
(1) elective contributions made by a Company on the Employee’s behalf pursuant to a cash or deferred arrangement described in Section 401(k) of the Code or an election under Section 125 or 132(f)(4) of the Code, and (2) (i) lump
sum compensation paid to supervisory employees of National Fuel Resources, Inc., National Fuel Gas Supply Corporation, National Fuel Gas Distribution Corporation or Horizon Energy Development, Inc., that is designated for payroll and human resources
purposes as “lump sum pay” in lieu of a base increase, (ii) discretionary bonuses paid to salaried employees of National Fuel Resources, Inc., before February 1, 2014, (iii) bonuses paid under the Seneca Resources Corporation Annual
Cash 

  
 - 18 - 













 
Bonus Program before February 1, 2014, (iv) Executive Annual Cash Incentive Program (EACIP) payments, (v) Annual At Risk Compensation Incentive Plan (AARCIP) payments, and (vi) annual
bonuses paid to officers who are “non-16b officers” at the time the bonus is paid. Company Contribution Compensation will specifically exclude any other compensation amount not described in this
Section 3.2(b). 
 The Company Contribution Compensation of a Post-2003 Participant taken into account in any Plan Year beginning after
December 31, 2002, will not exceed $200,000. The $200,000 limit will be adjusted for cost-of-living increases in accordance with Section 401(a)(17) of the Code. The
cost-of-living adjustment in effect for a calendar year applies to Company Contribution Compensation for the Plan Year that begins with or within such calendar year.

 (c)     Notwithstanding the foregoing, for a Participant who becomes an Eligible Employee in connection with a
change in employment which results in such Employee ceasing to participate in the Union Plan, such Employee’s Company Contributions under the Union Plan (if any) will continue on the same terms as in effect on the most recent Entry/Adjustment
Date, until the next Entry/Adjustment Date, but such contributions will be made to this Plan following such change in employment. 

Section 3.3     Matching Contributions. For each payroll period during which a
Participant (other than individuals who are employed as a “Customer Support Representative I” or “Customer Support Representative II”) makes Salary Reduction Contributions in accordance with Section 3.1, the Company will
contribute to the Plan for the benefit of the Participant in an amount equal to the Participant’s Base Salary for such payroll period, multiplied by the Matching Contribution Percentage determined in accordance with the tables that follow
(“Matching Contributions”). For purposes of calculating the Matching Contributions for any payroll period, the following rules apply: 

(a)     Base Salary for the applicable period will be the Participant’s Base Salary in effect on the
immediately preceding Entry/Adjustment Date. 
 (b)     The Matching Contribution Percentage will be determined
under the following tables with reference to the rate of Salary Reduction Contributions under Section 3.1 in effect during the period and the Participant’s Years of Service. For Participants whose classification as an Eligible Employee
changes, for example, changing from being Group I Employees to Group II Employees, the Matching Contribution Percentage determined under the respective table as of the most recent Entry/Adjustment Date will continue to be applicable following such
classification change, until the next Entry/Adjustment Date. 
 (c)     A Participant’s Years of Service
will be determined as of the Entry/Adjustment Date coincident with or immediately preceding the applicable period. 
 (d)
    Notwithstanding the foregoing, for a Participant who becomes an Eligible Employee in connection with a change in employment which results in such Employee ceasing to participate in the Union Plan, such Employee’s
Matching Contributions under the Union Plan (if any) will discontinue and Matching Contributions will be made to this Plan following such 

  
 - 19 - 













 
change in employment, based on the contribution election under the Union Plan (if any) and the Participant’s Years of Service as of the most recent Entry/Adjustment Date with the Matching
Contribution Percentage determined under the respective table under the Union Plan as of the most recent Entry/Adjustment Date, until the next Entry/Adjustment Date.

 Section 3.4     Rollover Contributions. If permitted under a
uniform, non-discriminatory policy adopted by the Committee, a rollover contribution from another qualified plan may be made to the Plan by a Participant, as long as: 

(a)     the Participant was a participant under another plan that was qualified under Section 401(a) of the
Code or an annuity plan under Section 403(a) of the Code; 

  
 - 20 - 













 (b)    in the case of a plan qualified under Section 401(a)
of the Code, the trust under such other plan is exempt from tax under Section 501(a) of the Code; 

(c)    the Participant receives a distribution from another plan and that plan qualifies as an eligible rollover
distribution, as described in Section 402(c) of the Code; 
 (d)    the Participant furnishes evidence
satisfactory to the Committee that the contribution meets conditions (a), (b) and (c); 
 (e)    a rollover
contribution that is not a direct rollover as described in Section 401(a)(31) of the Code, is made no later than the 60th day after receipt of the distribution; and 

(f)    no rollover contributions may be accepted from a conduit individual retirement account or annuity. 

A rollover contribution will be held in a separate “Rollover Account” established and maintained by the Committee as a permanent
accounting record under the Plan for the benefit of the Participant who made the rollover contribution. A Participant will at all times have a 100% nonforfeitable right to the value of the assets held in his or her Rollover Account. Amounts
allocated to a Rollover Account will be held in trust and invested in accordance with the terms and conditions of the Plan. Distributions of amounts allocated to a Rollover Account will be made when the Participant retires, dies, is disabled or
otherwise has a Severance from Employment in accordance with the terms and conditions of the Plan. 
 Section 3.5
    Forfeitures. Forfeitures resulting from the application of Sections 4.2 and 13.11 will not be applied to directly increase the allocation that any Participant would otherwise receive under the Plan.
Forfeitures will be used to reduce (but not below zero) the Company Contribution under Section 3.2 for the calendar month in which the forfeitures become available. Any remaining forfeitures will be held in a suspense account and used to reduce
Company Contributions for subsequent calendar months. If the forfeitures exceed the total of Company Contributions for the Plan Year in which the forfeitures become available, the excess forfeitures will be used to reduce the Matching Contributions
under Section 3.3 for the Plan Year in which the forfeitures occur. If a suspense account is in existence at any time during a Plan Year pursuant to this Section, that account will not participate in the allocation of the Trust’s
investment gains and losses. 
 Section 3.6    Miscellaneous Contribution Rules. 

(a)    Limitations on Contributions. Salary Reduction Contributions, Company Contributions and
Matching Contributions (collectively, the “Total Contributions”) under this Article are subject to the following limitations: 

(1)     the sum of the Total Contributions and other amounts treated as Annual Additions for any Plan Year
may not exceed the Maximum Company Contribution, as determined under Section 3.9; and 
 (2)
    Total Contributions may not exceed the maximum amount allowable as a deduction to the Company under Section 404 of the Code. 

  
 - 21 - 













 (b)     Timing of Contributions. The Company will deposit
a Participant’s Salary Reduction Contributions with the Trustees within the period of time permitted by the Code, ERISA and applicable regulations. Company contributions to the Trustees will be made by the Company no later than the time
prescribed by law for filing its federal income tax return (including extensions thereof) for its current taxable year and for each succeeding taxable year for the Plan Year that ends within or that is
co-terminus with the taxable year of the Company. The Company may contribute this amount or amounts at any time; and it may make any Company contribution in two or more installments. However, no Company
contribution will be made for any Plan Year to the extent that it would not be deductible. 
 Section 3.7
    Allocations of Contributions and Forfeitures. 
 (a)     Maintenance of
Accounts. The Committee will establish and maintain, as a permanent accounting record under the Plan, a “Savings Account,” a “Retirement Savings Account,” a “Matching Contribution Account,” a “Thrift
Account” and a “Rollover Account” in the name of each Participant. 
 (b)     Allocation of Salary
Reduction Contributions. The Committee will allocate to each Participant’s Savings Account the Participant’s Salary Reduction Contributions, if any, as of a date or dates determined by the Committee. 

(c)    Allocation of Matching Contributions. The Committee will allocate to the Matching Contribution
Account of each Participant so much of the total Matching Contributions for the calendar month and the forfeitures resulting from the application of Section 13.11, if any, as will equal the Participant’s Matching Contribution for the
calendar month, as determined under Section 3.3. The allocations will be made as of a date or dates determined by the Committee. 

(d)     Allocation of Company Contribution. As of the last business day of each month, commencing with
January 2004, the Committee will allocate to the Retirement Savings Account of each Post-2003 Qualified Participant the Participant’s Company Contribution for the calendar month, as determined under Section 3.2. The term “Post-2003
Qualified Participant” for any month means a Post-2003 Participant who is credited with at least one Hour of Service during that month and who either (1) is employed by the Company on the last day of the month or (2) terminates
employment during the month by reason of (i) retirement on or after his or her Normal Retirement Date or Disability Retirement Date or (ii) death. 

Section 3.8     Base Salary. Unless otherwise provided, the term “Base Salary” for any
Plan Year means Participant’s basic compensation for a payroll period, excluding compensation under the National Fuel Gas Company Deferred Compensation Plan, when deferred and when received, any amounts the Participant receives as overtime pay,
commissions or other special pay, fees, bonuses or allowances, but including salary contribution payments made by the Company on account of sickness or accident. 

Notwithstanding the foregoing, “Base Salary” includes contributions made by the Company pursuant to a salary reduction agreement
that are not includable in the Participant’s 

  
 - 22 - 













 
gross income under Section 125, 402(e)(3), 402(h) or 403(b) of the Code and, effective for Plan Years beginning on or after January 1, 2001, Section 132(f)(4) of the Code. 

The Base Salary of each Participant taken into account in determining allocations for any Plan Year beginning after December 31, 2001, shall
not exceed $200,000, as adjusted for cost-of-living increases in accordance with Section 401(a)(17)(B) of the Code. The
cost-of-living adjustment in effect for a calendar year applies to Base Salary for the determination period that begins with or within such calendar year. If a Participant’s Base Salary is determined over
a period of time that is shorter than 12-months, then the $200,000 limit, as adjusted, will be prorated for the number of full calendar months in the period. 

Section 3.9     Limitations on Allocations. 

(a)     Definitions. The following definitions (applied consistently with Code Section 415) apply
for purposes of this Section: 
 (1)     Annual Addition has the same meaning as defined
under Section 415(c)(2) of the Code and the regulations thereunder. 
 (2)
    Compensation includes wages within the meaning of Section 3401(a) and all other payments of compensation to a Participant by the Company (in the course of the Company’s trade or business) for which the
Company is required to furnish the Participant a written statement under Sections 6041(d), 6051(a)(3) and 6052 of the Code. Compensation under this paragraph (2) must be determined without regard to any rules under Section 3401(a) of the
Code that limit the remuneration included in wages based on the nature or location of the employment or the services performed (such as the exception for agricultural labor in Section 3401(a)(2) of the Code). Compensation also includes any
amount that would be included in wages but for an election under section 125(a), 132(f)(4), 402(e)(3), 402(h)(1)(B), 402(k), or 457(b). Compensation for any Plan Year shall not exceed the limit set forth in Section 401(a)(17) of the Code for
such Plan Year. 
 To the fullest extent permitted by Code Section 415 and the regulations thereunder, Compensation
shall also include (i) amounts paid to a Participant after the Participant has a Severance from Employment and (ii) compensation for periods of military service and/or disability. 

For purposes of applying the limitations of this Section, Compensation for a Limitation Year means the Compensation actually
paid or made available during the Limitation Year. Notwithstanding the preceding sentence, for Limitation Years beginning on or after January 1, 2002, Compensation for a Participant in a defined contribution plan who is permanently and totally
disabled (as defined in Section 22(e)(3) of the Code) is the Compensation the Participant would have received for the Limitation Year if the Participant had been paid at the rate of Compensation paid to him or her immediately before becoming
permanently and totally disabled. 

  
 - 23 - 













 (3)     Limitation Year means the Plan
Year, unless a different 12- consecutive-month period is designated pursuant to a written resolution adopted by the Board of Directors of National. 

(b)     Maximum Annual Addition. The Annual Addition that may be contributed or allocated to a
Participant’s account under the Plan for any Limitation Year shall not exceed the “Maximum Annual Addition,” which is the lesser of: 

(1)     $40,000, as adjusted for increases in the cost-of-living pursuant to Section 415(d) of the Code, or 
 (2)
    100 percent of the Participant’s Compensation for the Limitation Year. The Compensation limit referred to herein will not apply to any contribution for medical benefits after separation from service (within the
meaning of Section 401(h) or Section 419A(f)(2) of the Code) which is otherwise treated as an annual addition. 

(c)    Maximum Company Contribution means the aggregate of the Maximum Annual Additions of all Participants
for the Plan Year. 
 (d)     Adjustment to Reduce Annual Additions. If the Annual Addition exceeds the
limitation set forth in Section 3.9(b) for any Participant, such excess amount shall be corrected in accordance with the Employee Plans Compliance Resolution System as set forth in Revenue Procedure
2013-12, or any superseding guidance. 
 (e)    Incorporation of
Section 415 by Reference. The limitations and other provisions of Code Section 415 and Treasury Regulations promulgated thereunder with respect to annual contributions and benefit accruals under the Plan are hereby incorporated by
reference. 
 Section 3.10 ADP Test. 

(a)     In General. Annual allocations derived from Salary Reduction Contributions to a Participants’
Savings Accounts must satisfy one of the following tests: 
 (1)     The 125% Test. The
Average ADP for Participants who are Highly Compensated Employees may not exceed the prior Plan Year’s Average ADP for Participants who are Nonhighly Compensated Employees for the prior Plan Year multiplied by 1.25; or 

(2)     The Alternative Limitation Test. The Average ADP for Participants who are Highly
Compensated Employees may not exceed the lesser of the prior Plan Year’s Average ADP for Participants who are Nonhighly Compensated Employees for the prior Plan Year multiplied by 2 or the prior Plan Year’s Average ADP for Participants who
are Nonhighly Compensated Employees for the prior Plan Year plus 2 percentage points. 
 The Committee may calculate the ADPs of
Participants and, thus, determine whether the Plan satisfies the ADP Test under this Section by treating all or part of the Qualified 

  
 - 24 - 













 
Matching Contributions made with respect to any or all of the Participants as Salary Reduction Contributions. The Committee may not treat Qualified Matching Contributions as Salary Reduction
Contributions unless the Qualified Matching Contributions satisfy the conditions set forth in Section 1.401(k)-2(a)(6) of the Treasury Regulations. 

(b)     Definitions. The following definitions apply for purposes of the Plan: 

(1)     ADP, with respect to a Participant, means the ratio (expressed as a percentage) of
the amount of Salary Reduction Contributions and amounts treated as Salary Reduction Contributions, if any, allocated to the Participant’s account for a Plan Year to the Participant’s ADP Compensation for the Plan Year. The ADP of a
Participant with no Salary Reduction Contributions for a Plan Year is zero. For purposes of computing ADPs, an employee who would be a Participant but for the failure of the employee to make Salary Reduction Contributions is treated as a Participant
on whose behalf no Salary Reduction Contributions are made. 
 (2)     Average ADP, with
respect to a group of Participants, means the average of the ADPs for the group of Participants. 
 (3)
    ADP Compensation, with respect to any Participant, will be determined by the Committee in a manner that satisfies the requirements of Section 414(s) of the Code and the regulations thereunder. The period
used to determine a Participant’s ADP Compensation for a Plan Year is either the Plan Year or the calendar year ending within the Plan Year. Whichever period is selected must be applied uniformly to determine the ADP Compensation of every
Participant for the Plan Year. If the Participant participated in the Plan for less than the full Plan Year or calendar year, the Plan may take into account ADP Compensation for that portion of the Plan Year or calendar year during which the
Participant actually participated, provided this limit is applied uniformly for all Participants for the Plan Year. 
 (4)
    Highly Compensated Employee means an Employee who (i) was a 5% owner at any time during the Plan Year or the preceding Plan Year, or (ii) for the preceding Plan Year had Compensation from the Company
in excess of $80,000. The $80,000 amount is adjusted at the same time and in the same manner as under Section 415(d) of the Code, except that the base period is the calendar quarter ending September 30, 1996. 

For this purpose, “Determination Year” is the Plan Year and the “Look- Back Year” is the twelve month period immediately
preceding the Determination Year. 
 The rules in Temporary Treasury Regulation
Section 414(q)-1T, A-4 and Notice 97-45 in effect for a Determination Year will be used to determine if a former employee is
a Highly Compensated Employee for that Determination Year. 
 For Plan Years relevant to determining whether an Employee is a Highly
Compensated Employee for Plan Years beginning after December 31, 1996, the amendments to 

  
 - 25 - 













 
Section 414(q) of the Code will be treated as having been in effect for Plan Years beginning in 1996. 

Notwithstanding the foregoing, the Company elects, pursuant to Treasury Regulation Section 1.414(q)-1T, Q&A-14, to make the calendar
year calculation election. 
 (5)     Nonhighly Compensated Employee means an Eligible
Employee who is not a Highly Compensated Employee. 
 (6)     Qualified Matching
Contributions are Matching Contributions that are 100% nonforfeitable at all times and satisfy the requirements set forth in Section 1.401(k)-6 of the Treasury Regulations. 

(c)    Special Rules. 

(1)     Plan Aggregation - Coverage and Nondiscrimination. For purposes of this Section, if
this Plan satisfies the requirements of Sections 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 Sections 401(k), 401(a)(4), or 410(b) of the Code
only if aggregated with this Plan, then this Section will be applied by determining the ADP of Participants as if all the plans were a single plan. Plans may be aggregated under this paragraph only if they have the same plan year and use the same
ADP testing method. Any adjustments to the Nonhighly Compensated Employee ADP for the prior year are made in accordance with Notice 98-1 and any superseding guidance. 

(2)     Plan Aggregation - Highly Compensated Employee. For purposes of this Section, the ADP
for any Participant who is a Highly Compensated Employee for the Plan Year and who is eligible to have Salary Reduction Contributions allocated to his or her accounts under two or more arrangements described in Section 401(k) of the Code, that
are maintained by the Company, will be determined as if the Salary Reduction Contributions were made under a single arrangement. If a Highly Compensated Employee participates in two or more cash or deferred arrangements that have different plan
years, all cash or deferred arrangements ending with or within the same calendar year will be treated as a single arrangement. Notwithstanding the foregoing, certain plans will be treated as separate if mandatorily disaggregated under regulations
under Section 401(k) of the Code. 
 (3)    Timing of Contributions. For purposes of
the ADP Test, Salary Reduction Contributions must be made before the end of the 12-month period immediately following the Plan Year to which the contributions relate. 

(4)     Maintenance of Records. The Committee will maintain records that demonstrate
satisfaction of the ADP Test under this Section, including records indicating the extent to which the Plan used Matching Contributions to satisfy the test.

 Section 3.11     Distribution of Excess
Contributions. 
 (a)     In General. If for any Plan Year there are any Excess Contributions, then
on or before the last day of the following Plan Year, Excess Contributions will be distributed according to the following procedures: 

(1)     The Excess Contributions of the Highly Compensated Employee or Employees with the largest dollar
amount of Salary Reduction Contributions are reduced by distributing the amount required to cause the Highly Compensated Employee’s or Employees’ Salary Reduction Contributions to equal the Salary Reduction Contributions of the Highly
Compensated Employee or Employees with the next highest dollar amount. However, if a lesser reduction, when added to the total dollar amount already distributed under this step, would equal the total Excess Contributions, the lesser amount is
distributed. 
 (2)     Repeat (1) until all Excess Contributions are distributed. 

Distributions of Excess Contributions will be made first from unmatched Salary Reduction Contributions and, thereafter, simultaneously from
Salary Reduction Contributions that are matched and Matching Contributions that relate to such Salary Reduction Contributions. 

Notwithstanding the foregoing, if the Committee treats Qualified Matching Contributions as Salary Reduction Contributions for purposes of the
ADP Test, distributions of Excess Contributions will be made first from unmatched Salary Reduction Contributions and, thereafter, simultaneously from Salary Reduction Contributions and Qualified Matching Contributions that relate to such Salary
Reduction Contributions. 
 If any Excess Contributions are distributed more than 21⁄2 months after the last day of the Plan Year in which the Excess Contributions arose, then Code Section 4979 imposes an excise tax on the Company with respect to those amounts. 

(b)     Excess Contributions. The term “Excess Contributions” means, with respect to a Plan Year,
the excess of Salary Reduction Contributions and Qualified Matching Contributions, to the extent they are treated as Salary Reduction Contributions for purposes of the ADP Test, over the maximum amount of the contributions permitted under
Section 3.10(a). Excess Contributions also include the income allocable to the excess described in the preceding sentence. The income allocable to Excess Contributions is determined in accordance with Subsection (c). 

(c)    Allocable Income/Loss. 

(1)     General Rule. Except as provided in paragraph (2) below, a Participant’s
Excess Contributions with respect to a Plan Year are adjusted for any income or loss up through the end of such Plan Year (but not for the period between the end of the Plan Year and the date of the distribution). 

  
 - 27 - 













 (2)     Special Rule for 2006 and 2007 Plan
Years. Any Excess Contributions made by a Participant with respect to the 2006 and 2007 Plan Years are adjusted for any income or loss up through the date of distribution. 

(3)     The amount of income allocable to a Participant’s Excess Contributions under paragraph
(1) or (2) above will be determined by the Committee in a reasonable and consistent manner and in accordance with applicable Treasury Regulations. 

Section 3.12     ACP Test. 

(a)     In General. Annual allocations derived from Matching Contributions to the Matching Contribution
Accounts must satisfy one of the following tests: 
 (1)     The 125% Test. The Average ACP
for Participants who are Highly Compensated Employees may not exceed the prior Plan Year’s Average ACP for Participants who are Nonhighly Compensated Employees for the prior Plan Year, multiplied by 1.25. 

(2)     The Alternative Limitation Test. The Average ACP for Participants who are Highly
Compensated Employees may not exceed the lesser of (i) the prior Plan Year’s Average ACP for Participants who are Nonhighly Compensated Employees for the prior Plan Year, multiplied by 2, and (ii) the prior Plan Year’s Average ACP for
Participants who are Nonhighly Compensated Employees for the prior Plan Year, plus 2 percentage points. 
 The Committee may calculate the
ACPs of Participants and, thus, determine whether the Plan satisfies the ACP Test under this Section by treating all or part of the Salary Reduction Contributions as Matching Contributions. The Committee may not treat Salary Reduction Contributions
as Matching Contributions unless the Salary Reduction Contributions satisfy the conditions in Section 1.401(m)-1(b)(5) of the Treasury Regulations. The Committee may not include Salary Reduction
Contributions in the ACP Test unless the Plan satisfies the ADP Test both with and without the Salary Reduction Contributions included in the ACP Test. 

(b)     Definitions. The following definitions apply for purposes of the Plan: 

(1)     ACP, with respect to a Participant, means the ratio (expressed as a percentage) of
the amount of Matching Contributions and amounts treated as Matching Contributions allocated to the Participant’s account for a Plan Year to the Participant’s ACP Compensation for the Plan Year. 

(2)     Average ACP, with respect to a group of Participants, means the average of the ACPs
for the group of Participants. 
 (3)     ACP Compensation will have the same meaning as
the term ADP Compensation, as defined in Section 3.10(b)(3). 
 (c)    Special Rules. 

  
 - 28 - 













 (1)    Plan Aggregation - Coverage and
Nondiscrimination. For purposes of this Section, if the Plan satisfies the requirements of Code Section 40l(k), 401(a)(4) or 410(b) only if aggregated with one or more other plans, or if one or more of the other plans satisfy the
requirements of Code Section 401(k) 401(a)(4) or 410(b) only if aggregated with this Plan, then this Section will be applied by determining the Actual Deferral Percentage of Participants as if all of the plans are a single plan. Plans may be
aggregated to satisfy Code Section 401(k) only if they have the same plan year and use the same Actual Deferral Percentage testing method. Any adjustments to the Non-Highly Compensated Employee Actual
Deferral Percentage for the prior year will be made in accordance with Notice 98-1 and any superseding guidance. 

(2)     Plan Aggregation - Highly Compensated Employee. For purposes of this Section, the ACP
for any Participant who is a Highly Compensated Employee and who is eligible to have amounts allocated to his or her account under two or more plans described in Section 401(a) of the Code, or arrangements described in Section 401(k) of
the Code that are maintained by the Company, will be determined as if the total of the amounts was made under each plan. If a Highly Compensated Employee participates in two or more cash or deferred arrangements that have different plan years, all
cash or deferred arrangements ending with or within the same calendar year will be treated as a single arrangement. Notwithstanding the foregoing, certain plans will be treated as separate if mandatorily disaggregated under regulations under
Section 401(m) of the Code. 
 (3)     Maintenance of Records. The Committee will
maintain records that demonstrate satisfaction of the ACP Test under this Section, including the extent to which the Plan treated Salary Reduction Contributions as Matching Contributions to satisfy the ACP Test. 

(4)     Timing of Contributions. For purposes of the ACP Test, Matching Contributions will be
considered made for a Plan Year if made no later than the end of the 12-month period beginning on the day after the close of the Plan Year. 

Section 3.13     Distribution of Excess Aggregate Contributions. 

(a)     In General. If for any Plan Year there are any Excess Aggregate Contributions, then on or
before the 15th day of the third month following the end of such Plan Year, Excess Aggregate Contributions may be forfeited, if forfeitable, or if not forfeitable, distributed according to the following procedures: 

(1)     The Excess Aggregate Contributions of the Highly Compensated Employee or Employees with the largest
dollar amount of Matching Contributions are reduced by distributing the amount required to cause the Highly Compensated Employee’s or Employees’ Matching Contributions to equal the Matching Contributions of the Highly Compensated Employee
or Employees with the next 

  
 - 29 - 













 
highest dollar amount. However, if a lesser reduction, when added to the total dollar amount already distributed under this step, would equal the total Excess Aggregate Contributions, the lesser
amounts distributed. 
 (2)     Repeat (1) until all Excess Aggregate Contributions are distributed.

 The Committee will treat a Highly Compensated Employee’s allocable share of Excess Aggregate Contributions, on a pro rata basis, as
attributable to Matching Contributions and to the Salary Reduction Contributions related to those Matching Contributions that the Committee treated as Matching Contributions for purposes of the ACP Test. 

If any Excess Aggregate Contributions are distributed more than 21⁄2 months after the last day of the Plan Year in which the Excess Aggregate Contributions arose, then Code Section 4979 imposes an excise tax on the Company with respect to those amounts. 

(b)     Excess Aggregate Contributions. The term “Excess Aggregate Contributions” means,
with respect to a Plan Year, the excess of Matching Contributions and Salary Reduction Contributions, to the extent they are treated as Matching Contributions for purposes of the ACP Test, over the maximum amount of the contributions permitted under
Section 3.12(a). Excess Aggregate Contributions also include the income allocable to the excess described in the preceding sentence. The income allocable to Excess Aggregate Contributions is determined in accordance with Subsection (c). 

(c)     Allocable Income/Loss. 

(1)     General Rule. Except as provided in paragraph (2) below, a Participant’s
Excess Aggregate Contributions with respect to a Plan Year are adjusted for any income or loss up through the end of such Plan Year (but not for the period between the end of the Plan Year and the date of the distribution). 

(2)     Special Rule for 2006 and 2007 Plan Years. Any Excess Aggregate Contributions made by
a Participant with respect to the 2006 and 2007 Plan Years are adjusted for any income or loss up through the date of distribution. 

(3)     The amount of income allocable to a Participant’s Excess Aggregate Contributions under
paragraph (1) or (2) above will be determined by the Committee in a reasonable and consistent manner and in accordance with applicable Treasury Regulations. 

Section 3.14     Distributions of Excess Deferrals. 

(a)     In General. Excess Deferrals by a Participant will be distributed to the Participant no later
than the first April 15 following the close of the Participant’s taxable year, unless the Participant notifies the Plan that the Excess Deferrals or a portion thereof will be distributed from another plan. Notice under the preceding sentence
must be submitted to the Committee in writing no later than the first March 1 following the close of the Participant’s taxable year. Notwithstanding the foregoing, a Participant is deemed to have notified the Plan of


  
 - 30 - 













 
Excess Deferrals for the taxable year taking into account only Salary Reduction Contributions under the Plan. 

(b)     Excess Deferrals. The term “Excess Deferrals” means, with respect to a Participant, Salary
Reduction Contributions, together with other elective deferrals (as defined in Section 402(g)(3) of the Code), in excess of the dollar limitation under Section 3.1(c). Excess Deferrals also include the income allocable to the excess
described in the preceding sentence. The income allocable to Excess Deferrals is determined in accordance with Subsection (c). 

(c)     Allocable Income/Loss. 

(1)     General Rule. Except as provided in paragraph (2) below, a Participant’s
Excess Deferrals with respect to a Plan Year are adjusted for any income or loss up through the end of such Plan Year (but not for the period between the end of the Plan Year and the date of the distribution). 

(2)     Special Rule for 2007 Plan Year. Any Excess Deferrals made by a Participant with
respect to the 2007 Plan Year are adjusted for any income or loss up through the date of distribution. 
 (3)
    The amount of income allocable to a Participant’s Excess Deferrals under paragraph (1) or (2) above will be determined by the Committee in a reasonable and consistent manner and in accordance with applicable
Treasury Regulations. 
 Section 3.15     Coordinating Corrective Distributions. 

(a)     Correcting Excess Deferrals After Distributing Excess Contributions. The amount of Excess
Deferrals that may be distributed under Section 3.14 with respect to a Participant for a taxable year is reduced by any Excess Contributions previously distributed with respect to that Participant for the Plan Year beginning with or within that
taxable year. 
 (b)     Correcting Excess Aggregate Contributions After Distributing Excess
Deferrals. The amount of Excess Contributions to be distributed under Section 3.11 with respect to a Participant for a Plan Year is reduced by any Excess Deferrals previously distributed to that Participant for the Participant’s
taxable year ending with or within that Plan Year. 
 Section 3.16     Qualified Military
Service. 
 (a)     Uniformed Services Employment and
Re-employment Rights Act. Notwithstanding any provision of this Plan to the contrary, contributions, benefits and service credit with respect to qualified military service will be provided in
accordance with Section 414(u) of the Code. 
 (b)     Death Benefits Under Qualified Active Military
Service. In the case of a Participant who dies while performing qualified military service (as defined in Code Section 414(u)), the survivors of the Participant shall be entitled to any additional benefits (other than benefit accruals
relating to the period of qualified military service) provided under the Plan had 

  
 - 31 - 













 
the Participant resumed and then terminated employment on account of death. This Section 3.16(b) is effective with respect to deaths occurring on or after January 1, 2007. 

(c)     Differential Wage Payments. Salary and wages paid to a Participant that constitutes
“differential wage payments” within the meaning of Code Section 414(u)(12) shall be treated as Compensation for the purposes of Section 3.9(a)(2) to the extent required under Code Section 414(u). This Section 3.16(c) is
effective with respect to Compensation paid after December 31,2008. 
 (d)     Severance From
Employment. For purposes of Code Section 401(k)(2)(B)(i)(I), a Participant shall be treated as having been severed from employment during any period the Participant is performing service in the uniformed services described in Code
Section 3401(h)(2)(A). This Section 3.16(d) is effective for Plan Years beginning after December 31, 2008. 

Section 3.17     Automatic Salary Reduction Contribution Arrangement. 

(a)     Rules of Application. Automatic Salary Reduction Contributions will be made on behalf of
Covered Participants who do not have an affirmative election in effect regarding Salary Reduction Contributions. The amount of Automatic Salary Reduction Contributions made for a Covered Participant each pay period is equal to the Default Percentage
multiplied by the Covered Participant’s Base Salary for that pay period. 
 A Covered Participant will have a reasonable opportunity
after receipt of the notice described in section 3.17(a)(3) to make an affirmative election regarding Salary Reduction Contributions (either to have no Salary Reduction Contributions made or to have a different amount of Salary Reduction
Contributions made) before Automatic Salary Reduction Contributions are made on the Covered Participant’s behalf. Automatic Salary Reduction Contributions being made on behalf of a Covered Participant will cease as soon as administratively
feasible after the Covered Participant makes an affirmative election. 
 (b)     Definitions. 

(1)     A “Covered Participant” is a Participant who becomes a Participant for purposes of
Section 3.1 on or after January 1, 2013 and who does not have an affirmative election in effect regarding Salary Reduction Contributions. 

(2)     “Automatic Salary Reduction Contributions” are Salary Reduction Contributions contributed
to the Plan on behalf of Covered Participants who do not have an affirmative election in effect regarding Salary Reduction Contributions. A Covered Participant’s Base Salary will be reduced by an amount equal to any Automatic Salary Reduction
Contributions made on the Covered Participant’s behalf. 
 (3)     The “Default
Percentage” is 2%. 

  
 - 32 - 













 (c)     Notice Requirement. At least 30 days, but
not more than 90 days, before the beginning of the Plan Year, the Employer will provide each Covered Participant a comprehensive notice of the Covered Participant’s rights and obligations with regard to Automatic Salary Reduction Contributions,
written in a manner calculated to be understood by the average Covered Participant. If an employee becomes a Covered Participant after the 90th day before the beginning of the Plan Year and does not receive the notice for that reason, the notice
will be provided no more than 90 days before the employee becomes a Covered Participant but not later than the date the employee becomes a Covered Participant. 

The notice will accurately describe: (1) the amount of Automatic Salary Reduction Contributions that will be made on the Covered
Participant’s behalf in the absence of an affirmative election; (2) the Covered Participant’s right to elect to have no Salary Reduction Contributions made on his or her behalf or to have a different amount of Salary Reduction
Contributions made; and (3) how Automatic Salary Reduction Contributions will be invested in the absence of the Covered Employee’s investment instructions.

 ARTICLE 4 

NONFORFEITABLE RIGHT TO BENEFITS 

Section 4.1    Definitions. The following definitions apply for purposes of the
Plan: 
 (a)    Normal Retirement Age means age 65. 

(b)    Normal Retirement Date means the first day of the month coincident with or following
the Participant’s Normal Retirement Age. 
 (c)    Annuity Starting Date means the
first day that all events have occurred that entitle the Participant to the benefit. 
 (d)    Deferred
Retirement means the period beginning with a Participant’s Normal Retirement Date and ending with the date that he or she retires from the Company. 

(e)    Required Beginning Date means April 1 of the calendar year following the later of
the calendar year in which the Participant attains age 701⁄2 or the calendar year in which the Participant retires. The Required Beginning Date of a 5-percent owner (within the meaning of Section 416 of the Code), however, is the April 1 of the calendar year following the calendar year in which the Participant attains age 701⁄2. 

(f)    Beneficiary means any person (or entity) entitled to receive benefits under the Plan by
reason of the death of a Participant. 
 (g)    Prospective Beneficiary means, as to any
Participant, any person who (or entity which), under the Plan or any valid beneficiary designation then in effect, would become a Beneficiary on the death of the Participant. 

Section 4.2    Determination of Nonforfeitable Rights. 

(a)    Upon Retirement. A Participant who attains his or her Normal Retirement Date
while an Employee of the Company or an Organization Under Common Control is fully vested in, and has a 100% nonforfeitable right to, his or her accounts. 

(b)    Upon Death or Disability. A Participant who dies while an Employee of the
Company, or whose employment terminates by reason of becoming Totally and Permanently Disabled, is fully vested in, and has a 100% nonforfeitable right to, his or her accounts. Notwithstanding the foregoing, if the Participant has separated from the
service of the Company and then dies or becomes Totally and Permanently Disabled, the Participant’s nonforfeitable interest in his or her Retirement Savings Account is determined under the vesting schedule in Subsection (c). 

(c)    Upon Completion of Required Years of Vesting Service. A Participant will at all
times be fully vested in, and have a 100% nonforfeitable right to, his or her Savings Account, Matching Contribution Account, Thrift Account, and Rollover Account. Except as 

  
 - 34 - 













 
provided in Subsections (a) and (b), a Post-2003 Participant will have a nonforfeitable right to his or her Retirement Savings Account as follows: 

(1)    For Company Contributions made with respect to Plan Years beginning prior to January 1, 2007:

  

					
	 Number of Years of
Vesting
Service
	  	
Vested Percentage
	 
	 Less than 5
	  	 	0	% 
		
	 5 or more
	  	 	100	% 

 (2)    For Company Contributions made with respect to Plan Years beginning
on or after January 1, 2007: 
  

					
	 Number of Years of
Vesting
Service
	  	
Vested Percentage
	 
	 Less than 3
	  	 	0	% 
		
	 3 or more
	  	 	100	% 

 (d)    Forfeiture Following a Break in Service. In the
case of a Participant who incurs five (5) consecutive One-Year Breaks in Service, any nonvested amount in the Participant’s Retirement Savings Account shall be forfeited. Notwithstanding the
preceding sentence, in the case of a Participant who receives a distribution of his or her entire vested benefit under the Plan after incurring a Severance from Employment or becoming Totally and Permanently Disabled, any nonvested benefits in the
Participant’s Retirement Savings Account shall be forfeited; provided, however that the forfeited amounts will be restored if the Participant is rehired before incurring five (5) consecutive One-Year
Breaks in Service. For purposes of the preceding sentence, if the value of a Participant’s vested account balance is zero at the time of the Participant’s Severance from Employment or becoming Totally and Permanently Disabled, the
Participant shall be deemed to receive a distribution of such zero vested account balance and any nonvested benefits in the Participant’s Retirement Savings Account shall be forfeited.

 ARTICLE 5 

DISTRIBUTION OF BENEFITS 

Section 5.1    Forms and Time of Benefit Distributions. 

(a)    Entitlement to Benefits. A Participant is entitled to receive a distribution of
his or her nonforfeitable benefits under the Plan if the Participant has a Severance from Employment, has attained age 59 1⁄2, or has become Totally and
Permanently Disabled. 
 (b)    Severance from Employment. For purposes of the Plan,
the term “Severance from Employment” means the termination of a Participant’s employment with the employer maintaining the Plan. For this purpose, the term “employer” includes any entity which is aggregated with the employer
maintaining the Plan pursuant to Code Section 414(b), (c), (m), or (o). For example, if a Participant terminates his or her employment with the Company, but continues to be employed by any Organization Under Common Control, the Participant will
not have a Severance from Employment. A Participant also does not have a Severance from Employment if, in connection with a change of employment, the Participant’s new employer maintains the Plan with respect to the Participant. A new employer
maintains a plan with respect to a Participant by continuing or assuming sponsorship of the plan or by accepting a transfer of plan assets and liabilities (within the meaning of Code Section 414(1)) with respect to the Participant. 

(c)    Commencement of Distributions. Distribution of benefits to which a Participant becomes
entitled under Subsection (a) may commence as soon as practicable following the Participant’s satisfaction of the conditions in Subsection (a). 

Notwithstanding the foregoing, distribution of a benefit to a Participant under the Plan must commence no later than the earlier of: 

(1)    the Participant’s Required Beginning Date; or 

(2)    the 60th day after the close of the Plan Year in which occurs the latest of the following: 

 (i)      the date on which the Participant attains his or her Normal Retirement Date, 

 (ii)     the 10th anniversary of the year in which the Participant commenced participation in
the Plan, 
  (iii)    the date the Participant terminates his service with the Company (or
Organization Under Common Control), or 
  (iv)    a date that is later than the dates described in
(i), (ii) and (iii) above and that is specified in a written election made by the Participant. The failure of a Participant to apply for and consent to a 

  
 - 36 - 













 
distribution pursuant to Section 5.5 is deemed to be an election to defer commencement of payment. 

(d)    Form of Distribution. In general, distributions shall be made in cash. However,
a Participant may elect, in the manner prescribed by the Committee, to receive distributions from National Stock Fund A and National Stock Fund B in the form of cash or common stock of National. 

Section 5.2    Amount of Distribution. When a Participant becomes entitled to receive a
distribution of a benefit in accordance with this Section, he or she may elect a full or partial distribution, provided that a Participant may not receive more than one partial distribution during any calendar year, and a Participant may not receive
a partial distribution of less than $1,000. 
 Section 5.3     Designation of Death Beneficiary. A
Participant may designate a specific Prospective Beneficiary, including any class of Prospective Beneficiaries or any contingent Prospective Beneficiaries, for the benefits provided on his or her death under the Plan. The designation may be changed
from time to time. All designations must be made in a manner acceptable to the Committee and will be effective when filed with the Committee. 

A married Participant may designate a Prospective Beneficiary other than his or her spouse if the spouse consents in writing to the
designation. Spousal consent will not be required if it is established to the Committee’s satisfaction that spousal consent cannot be obtained because either there is no spouse or the spouse cannot be located, or because of other circumstances
as provided for in applicable regulations. This consent must acknowledge the effect of the designation and must be witnessed by a representative of the Committee or notary public. No designation will be effective if the Prospective Beneficiary may
be changed without the spouse’s consent, unless the spouse’s consent expressly permits the Participant to make changes in Prospective Beneficiary designations without any requirement of the spouse’s further consent. Any consent under
this Section will be effective only with respect to the spouse who gave his or her consent. 

Section 5.4    Death Benefit Provisions. 

(a)    Normal Form of Payment of Death Benefits. If a Participant dies before the
distribution of his or her benefits under the Plan, the Participant’s entire nonforfeitable interest in the Plan will be distributed to his or her Beneficiary in a single lump sum payment in cash and/or property (as determined by the Committee
in accordance with a uniform, nondiscriminatory policy) as soon as practicable, but in no event later than December 31 of the calendar year in which the fifth anniversary of the Participant’s death occurs (but in the case of a Participant
described in Section 5.6(b)(1), no later than December 31, 2010). Notwithstanding the foregoing, a Beneficiary may elect, in the manner prescribed by the Committee, to receive distributions from National Stock Fund A and National Stock
Fund B in the form of common stock of National. 
 (b)    Multiple Beneficiaries; Order of
Taking. In general, if a Participant is survived by one or more primary Beneficiaries, benefits payable by reason of the Participant’s 

  
 - 37 - 













 
death will be paid only to the surviving primary Beneficiaries, and no benefit will be payable to any contingent Prospective Beneficiary. Moreover, if at least one, but fewer than all, of the
primary Prospective Beneficiaries, become Beneficiaries on the Participant’s death, the percentage interest of each in the benefit payable by reason of the Participant’s death will be distributed to the remaining Beneficiaries in the ratio
determined by comparing the percentages specified by the deceased Participant for those Beneficiaries and adjusting those percentages accordingly. (For example, if the Participant had designated three primary Prospective Beneficiaries and indicated
percentages of 20%, 30% and 50% for them respectively, and if the primary Prospective Beneficiary who would have received the 50% interest predeceases the Participant, the surviving Beneficiaries would share the 50% potential interest of the
deceased Prospective Beneficiary in a 2:3 ratio, increasing their respective interest to 40% and 60%.) 
 Notwithstanding this general rule,
if the Participant’s designation of Prospective Beneficiaries clearly and unambiguously (in the sole judgment of the Committee) indicates that the interest of a particular primary Prospective Beneficiary who predeceases the Participant is to be
paid to one or more specified contingent Beneficiaries (to the exclusion, as to the interest, of all other primary Beneficiaries) and indicates the amount to be paid to each such contingent Beneficiary or the manner in which the amount is to be
calculated, the interest of the deceased Prospective Beneficiary will be paid to the designated contingent Beneficiaries in the amounts so determined. If more than one, but fewer than all the contingent Prospective Beneficiaries become Beneficiaries
by reason of the death of the Beneficiary, the interest of the deceased contingent Prospective Beneficiary (or Prospective Beneficiaries) will be divided among the surviving contingent Beneficiaries identified as to the portion to be distributed
hereunder applying the ratio principle articulated in the preceding paragraph, and if no such contingent Prospective Beneficiaries survive the Participant, then the interests of all of the contingent Prospective Beneficiaries in that portion will be
allocated among the surviving primary Prospective Beneficiaries applying the ratio principle articulated in the preceding paragraph. 

(c)    Absence of an Effective Beneficiary Designation. In the absence of an otherwise
effective beneficiary designation, death benefits are payable in the following order of priority: 

(1)    surviving spouse, and 

(2)    estate. 

(d)    Effect of Divorce. Upon the later to occur of the effective date of the divorce
of the Participant and his or her former spouse or the date on which the Committee receives written notification of the divorce, except as may otherwise be provided in a Qualified Domestic Relations Order, the rights of the former spouse under the
Plan will be extinguished, and any designation of that former spouse as a Prospective Beneficiary under the Plan will be null and void unless reaffirmed by the Participant after the effective date of the divorce in a written instrument directed to
the Committee and delivered to the Committee during the Participant’s lifetime. 
 (e)    Order of
Death. If it is impossible to ascertain with certainty the order of death of the Participant and any Prospective Beneficiary, the Participant will be deemed to have 

  
 - 38 - 













 
survived the Prospective Beneficiary unless the Participant has specifically indicated to the contrary in writing on his or her beneficiary designation form. If it is impossible to ascertain with
certainty the order of death of two or more Prospective Beneficiaries, deceased primary Prospective Beneficiaries will be deemed to have survived deceased contingent Prospective Beneficiaries, unless the Participant has specifically indicated
otherwise in writing on his or her beneficiary designation form. 
 (f)    Effect of
Disclaimers. To the extent that a Participant’s surviving spouse or any other Beneficiary disclaims in a writing that is notarized, or that has been witnessed and authorized to the satisfaction of the Committee, all or part of
any interest in a benefit payable by reason of the Participant’s death, the Beneficiary will cease to be considered a Beneficiary under the Plan. 

Section 5.5    Early Distribution Consent. 

(a)    In General. If the Participant’s nonforfeitable interest in the Plan exceeds
the Cash-Out Limit, no distribution will be paid to the Participant before the Participant’s Required Beginning Date, unless the Participant consents to the distribution. 

(b)    Valid Consent. A Participant’s consent is not valid unless the Participant
has received a notice containing a general description of the material features of the Plan. The notice must be written in a manner that would satisfy the notice requirements of Section 417(a)(3) of the Code. The notice must be provided no less
than 30 days and no more than 180 days before the Annuity Starting Date. In addition, the Participant must be informed of the right to defer receipt of the distribution. A consent also will not be valid if a significant detriment is imposed under
the Plan on any Participant who does not consent to the distribution. Finally, written consent of the Participant to the distribution must not be made before the Participant receives the aforementioned notice and must not be made more than 180 days
before the Annuity Starting Date. 
 If a distribution is one to which Sections 401(a)(l 1) and 417 of the Code do not apply, the
distribution may commence less than 30 days after the notice required under Section 1.41l(a)-l1(c) of the Treasury Regulations is given, if: 

(1)    the Committee 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 

(2)    the Participant, after receiving the notice, affirmatively elects a distribution. 

Section 5.6    Minimum Distribution Required. 

(a)    General Rule. Except as provided in Subsection (b) below, a Participant must
receive a distribution of his or her entire nonforfeitable interest in the Plan on or before his or her Required Beginning Date. If the Participant subsequently becomes entitled to an additional interest in the Plan, the Participant must receive a
distribution of his or her entire nonforfeitable 

  
 - 39 - 













 
interest in the Plan, if any, on or before December 31 of each calendar year including and following the year of the Required Beginning Date. 

(b)    Exceptions. 

(1)    A Participant whose Required Beginning Date is April 1, 2009 will receive the required minimum
distribution for the 2008 distribution calendar year on or before April 1, 2009. The Participant will not receive a required minimum distribution for the 2009 distribution calendar year but will receive a lump sum distribution of his or her
entire nonforfeitable interest in the Plan on or before December 31, 2010. 
 (2)    A Participant
whose Required Beginning Date is April 1, 2010 will not receive a required minimum distribution for the 2009 distribution calendar year but will receive a lump sum distribution of his or her entire nonforfeitable interest in the Plan on or
before December 31, 2010. 
 (c)    Definitions. For purposes of this Section,
required minimum distributions shall be determined in accordance with Section 14.3, and the term “distribution calendar year” shall have the meaning set forth in Section 14.4. 

Section 5.7    Involuntary Cash-Outs of Small Benefits. Notwithstanding any other
provision of this Article, a Participant who has a Severance from Employment will receive a distribution of his or her entire nonforfeitable interest in the Plan in a single lump sum payment of cash or property, provided that the amount of the
distribution does not exceed the Cash-Out Limit. A distribution under this Section 5.7 will be made as soon as administratively feasible following the Participant’s Severance from Employment. A
distribution made pursuant to this Section 5.7 will be made without the consent of the Participant. 

Section 5.8    Hardship Withdrawals. 

(a)    General Rule. Upon the application of any Participant, the Committee, in
accordance with a uniform, nondiscriminatory policy, may permit the Participant to make a withdrawal from his or her Savings Account and, effective July 1, 1998, his or her Rollover Account, if any, if and only if the following two requirements
have been satisfied: 
 (1)    the withdrawal is made on account of an immediate and heavy financial need
of the Participant; and 
 (2)    the withdrawal is necessary to satisfy such financial need. 

(b)    Limit on Distributable Amount. A hardship withdrawal under this Section must be
limited to the Distributable Amount. “Distributable Amount” means the sum of (i) the Participant’s total Salary Reduction Contributions as of the date of withdrawal and (ii) the value of the Participant’s Rollover
Account as of the Valuation Date coincident with or immediately preceding the date of withdrawal, the sum of which will be reduced by (iii) the amount of previous hardship withdrawals. 

  
 - 40 - 













 (c)    Immediate and Heavy Financial
Need. A withdrawal will be deemed to be made on account of an immediate and heavy financial need of the Participant only if the withdrawal is for: 

(1)    Expenses for medical care described in Section 213(d) of the Code previously incurred by the
Participant, his or her spouse, or any dependents of the Participant (as defined in Section 152 of the Code, and, for taxable years beginning on or after January 1, 2005, without regard to Subsections (b)(1), (b) (2), and (d)(1)(B) of
Section 152 of the Code) or that are necessary for these persons to obtain such medical care; 

(2)    Costs related directly to the purchase of a principal residence for the Participant (excluding
mortgage payments); 
 (3)    Payment of tuition, related educational fees and room and board expenses
for the next 12 months of post secondary education for the Participant, his or her spouse, children or dependents (as defined in Section 152 of the Code, and, for taxable years beginning on or after January 1, 2005, without regard to
Subsections (b)(1), (b)(2), and (d)(1)(B) of Section 152 of the Code); 
 (4)    Payments necessary
to prevent the eviction of the Participant from his or her principal residence or foreclosure on the mortgage of the Participant’s principal residence; 

(5) Payments for burial or funeral expenses for the Participant’s deceased parent, spouse, children or dependents (as
defined in Section 152 of the Code, and, for taxable years beginning on or after January 1, 2005, without regard to Section 152 (d)(1)(B) of the Code); 

(6)    Expenses for the repair of damage to the Participant’s principal residence that would qualify
for the casualty deduction under Section 165 of the Code (determined without regard to whether the loss exceeds 10% of adjusted gross income); or 

(7)    Other deemed immediate and heavy financial needs prescribed by the Commissioner of Internal Revenue
in guidance of general applicability published in the Internal Revenue Bulletin. 
 (d)    Necessary to
Satisfy Financial Need. A withdrawal will be deemed necessary to satisfy an immediate and heavy financial need of a Participant only if all of the following requirements are satisfied: 

(1)    The withdrawal is not in excess of the amount of the Participant’s immediate and heavy
financial need. The amount of the immediate and heavy financial need may include any amounts necessary to pay any federal, state or local income taxes or penalties reasonably anticipated to result from the withdrawal. 

  
 - 41 - 













 (2)    The Participant has obtained all distributions,
other than hardship distributions, and all nontaxable (at the time of the loan) loans currently available under all qualified plans maintained by the Company. See Section 8.4(c) for a special rule pertaining to the distribution of dividends
from the ESOP portion of the Plan. 
 (3)    A Participant who receives a distribution of Salary
Reduction Contributions on account of hardship will be prohibited from making Salary Reduction Contributions to the Plan and all other plans of the Company for six (6) months after receipt of the hardship distribution. 

(e)    Uniform Rules. The Committee will adopt uniform rules of general applicability
regarding the timing and frequency of withdrawals, and the method by which earning will be credited to amounts withdrawn for the period prior to the withdrawal. 

Section 5.9    Loans to Participants. 

(a)    Trustees May Make Loans. Upon the Committee’s written direction and subject
to a uniform nondiscriminatory policy adopted by the Committee, the Trustees will make loans to Participants pursuant to this Section and any additional consistent rules the Committee may adopt. Loans will be made available to Participants who are
parties in interest (as defined under ERISA) on a reasonably equivalent basis and will not be made available to Highly Compensated Employees, officers or shareholders in an amount greater than the amount made available to other Participants.
Notwithstanding the foregoing, loans are permitted only from amounts held in a Participant’s Savings Account or Rollover Account. 

(b)    Written Applications. The Committee will prescribe an application procedure for
the loan program under the Plan, including use of an automated loan application system. 
 (c)    Limit on
Amount of Loan. The dollar amount of a loan to any Participant when added to any other loans granted under this Section, may not exceed the lesser of: 

(1)    $50,000, reduced by the excess (if any) of: 

 (i)    the highest outstanding balance of loans from the Plan during the one-year period ending on the day before the date on which such loan was made, over 

 (ii)    the outstanding balance of loans from the Plan on the date on which such loan was made; or

 (2)    one-half of the Participant’s nonforfeitable
interest in the Participant’s Savings Account and Rollover Account. 

  
 - 42 - 













 The Committee, pursuant to nondiscriminatory uniform rules of general application, may
impose a minimum loan amount requirement and may limit the maximum number of loans which may be outstanding under the Plan. 

(d)    Term and Interest Rate. The term of any loan granted under this Section may not
exceed five years, except in the case of a loan used to acquire a dwelling unit that, within a reasonable time (determined at the time the loan is made), is to be used as the Participant’s principal residence. The unpaid balance of any loan
must bear a reasonable rate of interest. The loan must be repaid in substantially level payments (with payments not less frequently than quarterly) over the term of the loan. 

(e)    Promissory Note Required. Each loan must be evidenced by a promissory note or
notes made, executed and delivered by the applying Participant to the Committee, and each note or notes must be in a form and contain the terms and conditions required by the Committee. 

(f)    Security. Each loan to a Participant under this Section must be adequately
secured by the Participant’s nonforfeitable interest in the Plan. No more than 50% of the Participant’s nonforfeitable interest in the Plan may be considered by the Plan as security for the outstanding balance of all Plan loans made to the
Participant. 
 On default, the balance of the amount owed by a Participant may be charged by the Committee or Trustee against the
Participant’s interest in the Plan. However, foreclosure on a note and attachment of security will not occur until a distribution under the Plan occurs. 

(g)    Directed Investment. Any application for a loan under this Section will
constitute a direction by the Participant that his or her nonforfeitable interest in the Plan be invested in the loan. If a loan is made under this Section, the value of a Participant’s account will be adjusted as of each Valuation Date to
reflect any principal and interest credited to the account as a result of the repayment of the loan by the Participant hereunder. 

(h)    No Loans to Shareholder-Employee or Owner Employee. No loans will be made to any
“shareholder-employee” or any “owner-employee”. For purposes of this requirement, a “shareholder-employee” means an employee or officer of an S corporation who owns (or is considered as owning within the meaning of
Section 318(a)(1) of the Code), on any day during the taxable year of the corporation, more than 5% of the outstanding stock of the corporation. An “owner-employee” means an individual who is a sole proprietor, or who is a partner
owning more than 10 percent of either the capital or profits interest of the partnership. Effective for Plan loans made after December 31, 2001, Plan provisions prohibiting loans to any shareholder-employee or owner-employee will cease to
apply. 
 (i)    Determination of Amount of Accrued Benefit Payable at Death or
Distribution. The portion of the Participant’s nonforfeitable interest used as a security interest held by the Plan by reason of a loan outstanding to the Participant will be taken into account as a reduction for purposes
of determining the amount of the accrued benefit payable at the time of death or distribution if the reduction is used as repayment of the loan.

 Section 5.10    Qualified Reservist
Distributions. A Participant may withdraw all or a portion of his or her Salary Reduction Contributions as a qualified reservist distribution, as defined in Section 72(t)(2)(G) of the Code, if each of the following requirements is
satisfied: 
 (a)    The Participant is a reservist in the U.S. Armed Forces who is ordered or called to active
duty for a period in excess of 179 days or for an indefinite period. 
 (b)    The distribution is made during
the period beginning on the date of the order or call described in (1) above and ending at the close of the active duty period described in (1) above. 

(c)    The Participant is ordered or called to active duty after September 11, 2001. 

Section 5.11    Special Thrift Account Withdrawal Rules. After receiving
the application of any Participant, the Committee, in accordance with uniform rules of general application, will permit the Participant to take a full or partial withdrawal of his or her Thrift Account. 

Section 5.12    Special Rule for Certain Withdrawals by Officers. An Officer may not take a
cash distribution funded by a voluntary disposition of any portion of his or her Account in National Stock Fund A or National Stock Fund B if, as a result of such distribution, the Officer would realize a “short-swing profit” recoverable
by the Company under Section 16(b) of the Securities Exchange Act of 1934, as amended.

 ARTICLE 6 

ACCOUNT VALUATIONS AND ALLOCATION OF NET EARNINGS 

Section 6.1    Valuation of Assets. As of each Valuation Date, the Trustees will value
the various accounts maintained by the Trustees for Participants and Beneficiaries, so that the Participant and Beneficiary accounts will reflect any increase or decrease in the fair market value of the assets of the Trust as of that date. Any
increase or decrease in market value will be apportioned in the same manner that income, expenses, and losses are to be apportioned in accordance with the provisions of this Article. The term “Valuation Date” means the close of the New
York Stock Exchange on each Business Day of each month and any other date or dates elected by the Committee. 

Section 6.2    Allocation of Income and Expenses. As of each Valuation Date, all income
of the Trust for the period since the preceding Valuation Date will be credited to, and all losses and expenses of the Trust for that period will be charged to the various accounts maintained by the Trustees for Participants and Beneficiaries. These
credits and charges will be made in proportion to the value of the respective accounts as of the preceding Valuation Date (after recording all credits and charges that would otherwise be made based on account balances as of the preceding Valuation
Date). Further, the Trustees may adjust in a nondiscriminatory and consistent manner the credits and charges that would otherwise be made based on account balances as of the preceding Valuation Date to take into account inter-fund transfers,
periodic contributions made on behalf of Participants, rollover contributions, or any other transactions occurring since the preceding Valuation Date. Notwithstanding the foregoing, any expenses of administration of the Plan that are paid from the
Trust will be charged to the various accounts maintained by the Trustees in a manner determined at the discretion of the Committee or, if the Committee has delegated its responsibilities under Section 8.1 to other persons, at the discretion of
those persons. 
 Section 6.3    Crediting Forfeitures and Contributions. After
adjusting each Participant’s account as of the last Business Day of the month, the Committee will credit the accounts of each Participant with his or her share of the Matching Contribution and Company Contribution with respect to such calendar
month, as determined pursuant to Section 3.7. After adjusting each Participant’s accounts as of the last Business Day of the Plan Year, the Committee will credit the accounts of each Participant with his or her share of the forfeited
accounts available for redistribution at the close of the Plan Year determined under Section 3.5. Salary Reduction Contributions will be credited to the respective accounts as of the end of each date on or immediately preceding when such
contributions were made. 
 Section 6.4    Alternative Accounting Procedures.
Notwithstanding the accounting procedures in Sections 6.1 and 6.2, the Committee may, for administrative purposes, instruct the Trustee to establish unit values for one or more funds (or for any portion thereof) and maintain the accounts setting
forth each Participant’s interest in the fund (or any portion thereof) in terms of a unit value, all in accordance with any rules and procedures that the Committee deems to be fair, equitable and administratively practicable. If unit accounting
is established for any fund (or any portion thereof) the value of a Participant’s interest in the fund at any time will 

  
 - 45 - 













 
be an amount equal to the then value of the unit in the fund (or any portion thereof) multiplied by the number of units then credited to the Participant. 

Section 6.5    Notification to Participants. The Committee will notify each Participant
of the amount of his or her interest in the Trust as of the close of each Plan Year. Such interest will consist of an amount equal to the total amounts credited to his or her accounts as a result of the adjustments under Sections 6.2 and 6.3. 

Section 6.6    Directed Investment Accounts. 

(a)    Participant Directed Investments. Notwithstanding any other provision of the Plan
or the Trust, a Participant or Beneficiary may, if permitted under a uniform, nondiscriminatory policy adopted by the Committee, direct that the Trustees invest amounts credited to his or her accounts in any manner authorized by the Plan or the
Trust and permitted under the Code. Directions must specify the amount and the securities or other property in which the amount is to be invested. The Committee, or the Trustees, may require that a Participant or Beneficiary clarify any directions
given under this Section. If a Participant makes any directions under this Section, the value of a Participant’s account is adjusted as of each Valuation Date to reflect any interest or dividends credited on the accounts or any increases or
decreases in the value of the investments directed by the Participant. 
 (b)    Fiduciary
Duties. In accordance with Section 404(c) of ERISA, no Participant or Beneficiary who directs an investment pursuant to this Section is considered a fiduciary by reason of his or her exercise of control over his or her
accounts, and no person who is otherwise a fiduciary (including the Committee, any individual to whom responsibilities are delegated under Section 10.6, or the Trustees) has any liability for any loss, or by reason of any breach, that results
from the Participant’s or Beneficiary’s exercise of control.

 ARTICLE 7 

THE TRUST 

Section 7.1    Continuation of the Trust. National will continue a Trust under the Plan. The
Trust will consist of all sums of money and other property acceptable to the Trustees that are paid or delivered to the Trustees, together with all investments made therewith and the proceeds thereof, and all earnings and profits thereon, less the
payments and distributions therefrom. The Trust will be administered in accordance with the Trust and the terms of the Plan. 

Section 7.2    Disbursements Limited to Trust Assets. Nothing contained in this Plan may be
construed as obligating the Trustee to make any payment or disbursements except from funds or property held under the Trust. 

Section 7.3    Expenses of Administration and Litigation. The reasonable costs, expenses, taxes and
liabilities incurred in connection with the administration of the Plan (including, without limitation, Trustee compensation, legal fees, and accounting and actuarial expenses) or in connection with any litigation involving the Trust will be paid
from the assets of the Trust, unless paid by the Company. No person who is a disqualified person (as defined in Section 4975 of the Code) and who receives full-time compensation from the Company, may receive compensation from the Trust,
although he or she may be reimbursed for expenses properly and actually incurred in connection with the administration of the Plan. The Committee will direct the Trustees in the payment of expenses and liabilities pursuant to this Section. 

Section 7.4    Pooled Investment Fund or Group Trust. Part or all of the assets of the Trust,
from time to time, may be transferred to (a) any pooled investment fund of an insurance company or (b) a common or collective trust fund or pooled investment fund maintained by a bank or trust company which contemplates the commingling for
investment purposes of the Trust assets with assets of other trusts. Transfers will be made in a manner consistent with the provisions of Section 4975(d)(8) of the Code.

 ARTICLE 8 

INVESTMENT AND VOTING OF SHARES 

Section 8.1    Investment of Contributions. 

(a)    Salary Reduction Contributions and Company Contributions. Subject to
Section 6.6, each Participant may make an investment election designating the Investment Fund(s) in which his or her future Salary Reduction Contributions and Company Contributions, as applicable, are to be invested. The following Investment
Funds shall be made available by the Committee under the Plan for the investment of Salary Reduction Contributions and Company Contributions: 

(1)    except with regard to the investment of Company Contributions, “National Stock Fund A,”
invested in common stock of National, which investment option shall only be frozen or removed, short of a Plan amendment, if the Committee determines (based upon advice of counsel) that to continue offering Company stock as an option would violate
ERISA; 
 (2)    the “Investment Contract Funds,” which are collective investment funds
invested primarily in investment contracts issued by insurance companies and commercial banks or other types of fixed principal investments selected by the Trustees of the Investment Contract Fund; 

(3)    one or more “Mutual Funds” (open-end regulated
investment companies) or similar funds selected by the Committee; and 
 (4)    any other investment duly
authorized by the Committee. 
 Each investment vehicle described in this Section, and each separate Mutual Fund or similar fund, is
considered a separate Investment Fund for purposes of the Plan, and a Participant’s interest in each such Investment Fund will be separately accounted for. A Participant may change his or her election pursuant to this Subsection (a) in
accordance with rules set forth by the Committee. In the absence of an election pursuant to this Subsection (a), a Participant’s Salary Reduction Contributions and Company Contributions will be invested in the default fund selected by the
Committee. 
 (b)    Matching Contributions. Matching Contributions will be invested
at the time of contribution in “National Stock Fund B,” which is invested in common stock of National. Subject to all necessary government approvals and applicable regulation, National is permitted, in its discretion, to make Matching
Contributions to National Stock Fund B either in cash or in shares of common stock of National. 

(c)    Reinvestment of Existing Balances. A Participant may, at any time, direct that
all or a portion of his or her existing account balances in one or more Investment Funds (including National Stock Fund B) be transferred among available Investment Funds in such percentages or fractions as he or she may specify, unless the
Committee promulgates rules and regulations concerning same, in which case the Participant must direct such transfers in a 

  
 - 48 - 













 
manner consistent with such rules and regulations. Notwithstanding the foregoing, Company Contributions may not be transferred to National Stock Fund A or B. A transfer becomes effective on the
day it is communicated to the Trustees through a telephone call by the Participant or other such method or methods as the Committee may require. The Committee may limit or prohibit transfers out of or into the Investment Contract Fund in order to
reflect requirements of contract(s) held in that Fund or in accordance with procedures established by the Committee to govern the operation of the Fund. 

Officers are subject to the following additional restrictions concerning transfers of their existing Account balances into or out of National
Stock Fund A, or out of National Stock Fund B. No Officer may transfer any portion of his or her existing Account balance into or out of National Stock Fund A, or out of National Stock Fund B, if, as a result of such transfer, the Officer would
realize a “short-swing profit” recoverable by the Company under Section 16(b) of the Securities Exchange Act of 1934, as amended. 

(d)    Investment Rules. The Committee may prescribe uniform rules of general
application concerning the investment of all contributions to the Plan. Those rules may limit the revocability of an investment election, restrict the transfer of contributions from one fund to another, and establish parameters for making temporary
investments. 
 (e)    Investment Direction by Beneficiary. In the event of a
Participant’s death, the Participant’s Beneficiary shall have the right to direct the investment of the Participant’s account balance in accordance with the provisions of this Section and Section 6.6, as if the Beneficiary were a
Participant. 
 Section 8.2    Voting of Shares. 

(a)    Voting of Common Shares. Each Participant has the right to give voting
instructions to the Trustees with respect to the number of shares of common stock of National that are held in the Trust on his or her behalf. Written notice of any meeting of stockholders of National and a form for instructing the Trustees how to
vote will be given to each Participant entitled to give instruction by such means and in such manner as the Committee may determine. The Trustees will vote such number of shares in accordance with those instructions; provided, however, that the
Trustees will vote those shares of common stock of National for which they have not received valid voting instructions from Participants in the same manner and in the same proportion as the shares of common stock of National with respect to which
the Trustees received valid voting instructions are voted. Each Participant will be informed that if he or she fails to return the voting instruction form, the shares for which the Participant is entitled to direct the voting will be proportionately
voted based on voting instructions actually received from other Participants. 
 (b)    Tender or Exchange
Offers. Notwithstanding any other provision of this Plan to the contrary, in the event of a tender or exchange offer for shares of common stock of National held by the Trustees in a Common Stock Fund for the account of any
Participant, the Trustees have no discretion or authority to sell, convey or exchange such shares except to the extent that the Trustees are timely directed to do so in writing by the Participant, and, upon


  
 - 49 - 













 
timely receipt of such written instructions, the Trustees will so sell, convey or transfer such shares of the common stock of National. 

In the event of a tender or exchange offer for shares of common stock of National held by the Trustees in a Common Stock Fund for the account
of any Participant, (i) each Participant will be informed that if he or she fails to timely instruct the Trustees to tender or exchange the shares held for the Participant’s account, the Trustees will not tender or exchange those shares;
(ii) National and the Committee will not interfere in any manner or in any way attempt to influence a Participant’s decision regarding the tender or exchange of those shares (hereinafter referred to as the “Investment Decision”);
(iii) National and the Committee will adequately communicate or cause to be communicated to the Participants the provisions of the Plan relating to the tender or exchange of the shares and timely distribute to Participants all communications
directed generally to the owners of the shares subject to the tender or exchange offer, and (iv) the Trustees will timely transmit to the Committee for distribution to Participants, all communications that the Trustees may receive, if any, from
the offeror of the tender or exchange offer relating to the tender or exchange offer. In no event will the communications to Participants with respect to Investment Decisions or public communications directed generally to the owners of the shares
subject to the tender or exchange offer, be deemed to be interference in the exercise of the Participant’s Investment Decision; provided, however, that Section 510 of ERISA will apply to any communication that threatens or intimates that
actions which would violate Section 510 of ERISA will or might be taken with respect to any Participant who does not make an Investment Decision in accord with the wishes of National. 

Section 8.3    Designation of National Stock Funds A and B as an ESOP. 

Effective on and after September 28, 2007, the portion of the Trust invested in National Stock Fund A and National Stock Fund B is designated as an
Employee Stock Ownership Plan (“ESOP”). The ESOP portion of the Plan is intended to be a stock bonus plan as defined in Treasury Regulation Section 1.401-1 (b)(1)(iii) and a non-leveraged employee stock ownership plan satisfying the requirements of Sections 401(a) and 4975(e) of the Code. The ESOP portion of the Plan is designed to be invested primarily in shares of National common
stock, which are qualifying employer securities within the meaning of Section 4975(e)(8) of the Code. 

Section 8.4    Dividends on Stock Held in the ESOP. 

(a)    Election between Distribution and Reinvestment Cash dividends paid with respect to
shares of stock held in the ESOP as of the record date for such dividends shall be, at the election of the Participant or Beneficiary, either (i) paid or distributed in cash to the Participant or Beneficiary, or (ii) paid to the applicable
National Stock Fund and reinvested in common stock of National. 
 (b)    Default
Election. Except as provided in Subsection (c) below, if a Participant or Beneficiary fails to make a proper election under Subsection (a) with respect to a dividend, the Participant or Beneficiary shall be deemed to
have elected to have the dividend paid to the applicable National Stock Fund and reinvested in common stock of National. 

(c)    Special Deemed Election for Hardship Withdrawals. If a Participant or
Beneficiary requests a hardship withdrawal under Section 5.8 which is approved between the 

  
 - 50 - 













 
ex-dividend date for a dividend and the due date for the election under Subsection (a) with respect to such dividend, the Participant or Beneficiary will be deemed to have elected that such
dividend be paid or distributed in cash to the Participant or Beneficiary. This deemed election will remain in effect for subsequent dividends unless the Participant or Beneficiary affirmatively elects to have dividends paid to the applicable
National Stock Fund and reinvested in common stock of National. 
 (d)    Cash
Distributions. If a Participant or Beneficiary elects a cash distribution, the distribution may, at the discretion of the Committee, be paid (i) directly to the Participant or Beneficiary or (ii) to the applicable
National Stock Fund and then distributed to the Participant or Beneficiary not later than ninety (90) days after the close of the Plan Year in which paid to such fund. 

(e)    Committee Discretion. The Committee shall determine the scope, manner and timing
of the elections, dividend payments or distributions, and reinvestment described in this Section 8.4 in any manner that is consistent with Section 404(k) of the Code and other applicable provisions of the Code and ERISA.

(a)    Top-Heavy Plan. The Plan will be considered a Top-Heavy Plan for a Plan Year (beginning with the first Plan Year beginning after December 31, 1983) if any of the following conditions exists: 

(1)    If the Top-Heavy Ratio for this Plan exceeds 60% and this
Plan is not part of any Required Aggregation Group or Permissive Aggregation Group of plans. 
 (2)    If
this Plan is a part of Required Aggregation Group of plans but not part of a Permissive Aggregation Group and the Top-Heavy Ratio for the Required Aggregation Group of plans exceeds 60%. 

(3)    If this Plan is a part of a Permissive Aggregation Group of plans and the Top-Heavy Ratio for the Permissive Aggregation Group exceeds 60%. 

(b)    Determination Date means the last day of the preceding Plan Year or, for the first Plan
Year, the last day of the first Plan Year. 
 (c)    Key Employee means any Employee or
former Employee (and the Employee’s Beneficiaries) who at any time during the Determination Period was an officer of the Company if the individual’s annual compensation exceeds 50% of the dollar limitation under Code
Section 415(b)(1)(A), an owner (or an individual considered an owner under Code Section 318 of one of the ten largest interests in the Company if the individual’s compensation exceeds 100% of the dollar limitation under Code
Section 415(c)(1)(A)), a 5% owner of the Company, or a 1% owner of the Company who has had an annual compensation of more than $150,000. Annual compensation means compensation as defined in Section 415(c)(3) of the Code, but for Plan Years
beginning after December 31, 1997, including amounts contributed by the employer pursuant to a salary reduction agreement that are excludable from the employee’s gross income under Sections 125, 402(e)(3), 402(h) or 403(b) of the Code,
and, effective for Plan Years beginning on or after January 1, 2001, Section 132(f)(4) of the Code. The “Determination Period” is the Plan Year containing the Determination Date and the four preceding Plan Years. The
determination of who is a Key Employee will be made in accordance with Code Section 416(i)(l) and the regulations thereunder. 

(d)    Top-Heavy Ratio means: 

(1)    If the Company maintains one or more defined contribution plans (including any Simplified Employee
Pension Plan) and the Company has not maintained any defined benefit plan that during the 5-year period ending on the Determination Date(s) has or has had accrued benefits, the
Top-Heavy Ratio for this Plan alone or for the Required or Permissive Aggregation Group as 

  
 - 52 - 













 
appropriate is a fraction, the numerator of which is the sum of all account balances of all Key Employees as of the determination dates(s) (including any part of any account balance distributed
in the 5-year period ending on the Determination Date(s)), and the denominator of which is the sum of all account balances (including any part of any account balance distributed in the 5-year period ending on the Determination Date(s)), both computed in accordance with Code Section 416 and the regulations thereunder. Both the numerator and denominator of the
Top-Heavy Ratio are increased to reflect any contribution not actually made as of the Determination Date, but which is required to be taken into account on that date under Code Section 416 and the
regulations thereunder. 
 (2)    If the Company maintains one or more defined contribution plans
(including any Simplified Employee Pension Plan) and the Company maintains or has maintained one or more defined benefit plans that during the 5-year period ending on the Determination Date(s) has or has had
any accrued benefits, the top-heavy ratio for any Required or Permissive Aggregation Group as appropriate is a fraction, the numerator of which is the sum of account balances under the aggregated defined
contribution plan or plans for all Key Employees, determined in accordance with Subsection (a), and the present value of accrued benefits under the aggregated defined benefit plan or plans for all Key Employees as of the Determination Date(s), and
the denominator of which is the sum of the account balances under the aggregated defined contribution plan or plans for all participants as of the Determination Date(s), all determined in accordance with Code Section 416 and the regulations
thereunder. The accrued benefits under a defined benefit plan in both the numerator and denominator of the top-heavy ratio are increased for any distribution of an accrued benefit made in the 5-year period ending on the Determination Date. 
 (3)    For purposes
of paragraphs (1) and (2) the value of account balances and the present value of accrued benefits will be determined as of the most recent valuation date that falls within or ends with the 12-month period
ending on the Determination Date, except as provided in Code Section 416 and the regulations thereunder for the first and second plan years of a defined benefit plan. The account balances and accrued benefits of a participant who is not a Key
Employee but who was a Key Employee in a prior year, or who has not been credited with at least one hour of service with any employer maintaining the plan at any time during the 5-year period ending on the
Determination Date will be disregarded. The calculation of the Top-Heavy Ratio, and the extent to which distributions, rollovers, and transfers are taken into account will be made in accordance with Code
Section 416 and the regulations thereunder. Deductible employee contributions will not be taken into account for purposes of computing the Top-Heavy Ratio. When aggregating plans the value of account
balances and accrued benefits will be calculated with reference to the Determination Dates that fall within the same calendar year. 

(4)    The accrued benefit of a Participant other than a Key Employee is determined under the method, if
any, that uniformly applies for accrual purposes 

  
 - 53 - 













 
under all defined benefit plans maintained by the Company, or if there is no method, as if the benefit accrued not more rapidly than the slowest accrual rate permitted under the fractional rule
of Code Section 411(b)(1)(C). 
 (e)    Required Aggregation Group includes:
(i) each qualified plan of the Company in which at least one Key Employee participates or participated at any time during the Determination Period (regardless of whether the plan has terminated), and (ii) any other qualified plan of the
Company that enables a plan described in (i) to meet the requirements of Code Sections 401(a)(4) or 410. 

(f)    Permissive Aggregation Group means the Required Aggregation Group of plans plus any
other Company plan or plans that, when considered as a group with the Required Aggregation Group, would continue to satisfy the requirements of Code Sections 401(a)(4) and 410. 

(g)    Top-Heavy Valuation Date means, with respect to
each Plan Year, the Determination Date. 
 (h)    Top-Heavy
Compensation has the same meaning as Compensation as defined in Code Section 415(c)(3). 

(i)    Qualified Top-Heavy Participant, for any
Plan Year in which the Plan is a Top-Heavy Plan, means any Participant who has not had a Severance from Employment at the end of the Plan Year, regardless of the Participant’s Hours of Service during the
Plan Year, Compensation for that year or failure to make Salary Reduction Contributions during the Plan Year. 

(j)    Super Top-Heavy Plan. The Plan will be
considered a Super Top-Heavy Plan if the Plan would meet the definition of a Top-Heavy Plan if 90% were substituted for 60% in each place it appears in Subsection
9.1(a). 
 (k)    Non-Key Employee means any
Employee of the Company who is not a Key Employee. 

Section 9.2    Top-Heavy Rules. 

(a)    Application of Top-Heavy Rules. If the
Plan is a Top-Heavy Plan for a Plan Year, the provisions of this Section will become applicable for the Plan Year. Notwithstanding the preceding sentence, the top-heavy
rules of this Section will not apply with respect to any Employee included in a unit of Employees covered by a collective bargaining agreement between Employee representatives and one or more employers if there is evidence that retirement benefits
were the subject of good faith bargaining between the Employee representatives and the employer or employers. 

(b)    Minimum Company Contribution. In any Plan Year in which the Plan is a Top-Heavy Plan, there will be allocated to each Qualified Top-Heavy Participant, before any other allocations are made under the Plan, the lesser of 3% of the
Participant’s Top-Heavy Compensation or the percentage at which contributions and forfeitures are allocated under the 

  
 - 54 - 













 
Plan for the Plan Year with respect to the Key Employee for whom the percentage is the highest for the Plan Year. The latter percentage will be determined by dividing the contributions (including
Salary Reduction Contributions) and forfeitures allocated to the Key Employee by his or her Top Heavy Compensation for the Plan Year. For purposes of this Section, Salary Reduction Contributions, matching contributions required to pass the actual
deferral percentage test of Code Section 401(k)(3), and matching contributions required to pass the actual contribution percentage test of Code Section 401(m), of an Employee who is not a Key Employee may not be considered in meeting this
minimum contribution requirement. If in any Plan Year the Plan is a Top-Heavy Plan, and a Non-Key Employee who is eligible to be a Participant hereunder also
participates in a defined benefit plan of the Company, the minimum contribution will be provided under the defined benefit plan. 

(c)    Limitation on Contributions and Benefit. For Plan Years beginning before
January 1, 2000, if the Plan is a Top-Heavy Plan in any Plan Year, 1.00 will be substituted for 1.25 in calculating the Defined Benefit Fraction and the Defined Contribution Fraction. Notwithstanding the
preceding sentence, in any Plan Year in which the Plan is a Top-Heavy Plan but not a Super Top-Heavy Plan, 1.00 will not be substituted for 1.25 if the Company makes an
additional minimum Company contribution under Subsection (b) by substituting 4% for 3%. 

(d)    Special Rule for Non-Key Employees in Two
Plans. For Plan Years beginning before January 1, 2000, if the Plan is a Top-Heavy Plan in any Plan Year, and an Employee who is not a Key Employee participates both in the Plan and
in a defined benefit plan that is top-heavy and that is included in an Aggregation Group, 5% will be substituted for 3% in Subsection (b) and 1.00 will not be substituted for 1.25 under Subsection
(c) if the Company makes an additional minimum contribution under Subsection (b) by substituting 71⁄2% for 3%. 

Section 9.3    Modification of Top-Heavy Rules. 

(a)    Effective Date. This section shall apply for purposes of determining whether the
Plan is a top-heavy plan under Section 416(g) of the Code for Plan Years beginning after December 31, 2001, and whether the Plan satisfies the minimum benefits requirements of Section 416(c) of
the Code for such years. This section amends the preceding provisions of this Article 9. 

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

  
 - 55 - 













 (c)    Determination of Present Values and
Amounts. This Section will apply for purposes of determining the present values of accrued benefits and the amounts of account balances of Employees as of the Determination Date. 

(1)    Distributions During Year Ending on the Determination Date. The present
values of accrued benefits and the amounts of account balances of an Employee as of the Determination Date shall be increased by the distributions made with respect to the Employee under the Plan and any plan aggregated with the Plan under
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 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.” 

(2)    Employees not Performing Services During Year Ending on the Determination
Date. The accrued benefits and accounts of any individual who has not performed services for the Company during the 1-year period ending on the Determination Date shall not be taken into
account. 
 (d)    Minimum Benefits—Matching Contributions. Matching
Contributions shall be taken into account for purposes of satisfying the minimum contribution requirements of Section 416(c)(2) of the Code and the Plan. The preceding sentence shall apply with respect to Matching Contributions under the Plan
or, if the Plan provides that the minimum contribution requirement shall be met in another plan, such other plan. Company Matching Contributions that are used to satisfy the minimum contribution requirements shall be treated as Matching
Contributions for purposes of the actual contribution percentage test and other requirements of Code Section 401 (m).

 ARTICLE 10 

ADMINISTRATION OF PLAN 

Section 10.1     Appointment of Committee. The Chief Executive Officer of National will appoint
a committee consisting at all times of one or more persons to be known as the “Committee”. Any person, including an officer, director, shareholder or employee of National is eligible for appointment as a member of the Committee. The Chief
Executive Officer of National may at any time remove a member of the Committee and appoint a successor. The Committee is a “named fiduciary” under Section 402(a)(l) of ERISA. 

Section 10.2     Administration of the Plan. The Committee has the full
discretionary authority and responsibility to control and manage the operation and administration of the Plan for the exclusive benefit of Participants and their Beneficiaries as required under ERISA and the Code. 

In its sole discretion, the Committee has the exclusive and complete authority to interpret the Plan and to determine all questions arising in
the administration, interpretation and application of the Plan. By way of example, and not by way of limiting the general grant of authority and discretion described above, the Committee will: be the sole and exclusive arbiter of all questions
arising with respect to issues under the Plan as to coverage and eligibility, both as to participation and as to benefits and the amount of benefits, and the determination of a Participant’s interest in the Trust; have the full and complete
discretion, authority and power to make factual determinations relating to the amount and manner of allocations and distributions of benefits; have the full and complete discretion, authority and power to determine whether a domestic relations order
constitutes a Qualified Domestic Relations Order and whether a putative Alternate Payee otherwise qualifies for benefits under the Plan; have the full and complete discretion, authority and power to determine whether the Plan has suffered a de facto
termination; and have the full and complete discretion, authority and power to make all factual findings. The Committee has the full and complete discretionary authority and power to correct any defect, supply any omission or reconcile any
inconsistency, including but not limited to mathematical or arithmetical errors, resolve any ambiguity and to construe the terms of the Plan, in any manner and to any extent that it deems necessary to carry out the purposes of the Plan. The
Committee may adopt any rules it deems advisable for administering the Plan. In all events, the Committee’s decision in any and all such matters will be binding and conclusive on all parties. 

The Committee is responsible for filing those returns with government agencies that are required to be filed by plan administrators under
ERISA and the Code. The Committee is also responsible for distributing those reports to Participants and Beneficiaries that are required to be distributed by plan administrators under ERISA and the Code. 

The Committee has full authority to control and manage the operation and administration of the Plan, except to the extent that the Trustees,
under the provisions of the Plan and the Trust Agreement, have exclusive authority and responsibility to manage and control the assets of the Plan. The Committee has the discretionary authority and power to select a successor Trustee. 

  
 - 57 - 













 Section 10.3     Compensation and Expenses.
Members of the Committee will serve without compensation in their capacity as Committee members. The Company or the Trust, as determined in accordance with Section 7.3, may pay the expenses of the Committee incurred in connection with the
administration of the Plan. 
 Section 10.4     Liability and Indemnification. Except
for their own gross negligence or willful misconduct, the members of the Committee and any individual to whom responsibilities are delegated under Section 10.6 are not liable to anyone for any act or omission in the course of the administration
of the Plan. In any case, to the extent permitted by law, the Company will indemnify the members of the Committee and any individual to whom responsibilities are delegated under Section 10.6 against any liability (not reimbursed by insurance)
incurred in the course of the administration of the Plan or the management of Trust assets, except liability arising from their own gross negligence or willful misconduct. 

Section 10.5     Agents. The Committee may employ any agents, including counsel, as it deems
advisable for the administration of the Plan. Agents need not be Participants under the Plan. 
 Section 10.6
    Delegation of Authority. 
 (a)     In General. The members of the
Committee may allocate their responsibilities among themselves or delegate other persons to carry out their responsibilities under Section 8.1 and Section 10.2. Any allocation or delegation of fiduciary responsibilities will be in writing,
approved by majority vote. An allocation or delegation may be changed or ended by majority vote. Any allocation or delegation may include the power to subdelegate without further recourse to the Committee. 

(b)     Liability. If the members of the Committee delegate responsibilities to other persons under
Subsection (a), they will not be liable for any act or omission of any person to whom such responsibilities are delegated, except as provided in Section 405(c)(2) of ERISA. 

Section 10.7     Actions by the Committee. Actions of the Committee will be by majority vote
either at a meeting or in writing without a meeting. However, a direction, certificate, statement or other declaration signed by a member of the Committee designated as a representative to sign such documents will be conclusive evidence of the
regularity of such direction, certificate, statement or declaration. 
 Section 10.8
    Disqualification of a Committee Member. A member of the Committee may not vote on any question relating specifically to himself or herself, or his or her Beneficiary. 

Section 10.9      Administrative Delays. To facilitate Plan mergers and spin-offs, changes in
administration or Plan design, market disruptions, and other comparable circumstances, the Committee may establish reasonable time periods during which Participants’ elections, distributions and withdrawals will be delayed. 

Section 10.10     Funding Policy. The Committee will establish and review the funding policy of
the Plan, taking into consideration the short-term need for liquidity in Trust 

  
 - 58 - 













 assets and the long-term goals for investment growth. The Committee will communicate the funding policy and
any changes of funding policy in writing to the Trustees. 
 Section 10.11     Valuation.
Notwithstanding the provisions of Article 6, the Committee may change its valuation methods and procedures at any time without advance notice to Participants. The Committee may, under unusual circumstances, direct that Participants’ accounts be
valued as of a date other than that provided under its normal rules to protect the financial integrity of the Plan or for other reasons the Committee deems appropriate. 

Section 10.12     Use of Electronic Media. To the extent permitted by the Code, ERISA and
applicable Treasury and Department of Labor Regulations, the Committee may disseminate Plan Information to Participants, former Participants and Beneficiaries, and may obtain elections and other information from Participants, former Participants and
Beneficiaries, in the form of an Electronic Communication. 
 If permitted by the Committee, a Participant, former Participant and
Beneficiary may, by means of an Electronic Communication and in accordance with rules and procedures established by the Committee, make decisions regarding his or her accounts. If this is done, he or she will be deemed to have given his or her
written consent and authorization to any action resulting from his or her Electronic Communication. 
 “Electronic Communication”
means a communication between a Participant, former Participant or Beneficiary and the Committee pursuant to an electronic or telephonic system maintained by the Committee or its delegee and communicated to Participants, former Participants and
Beneficiaries. 
 “Plan Information” includes certain notices, statements, summary plan descriptions, summaries of material
modifications, summary annual reports, and forms necessary for the operation of the Plan. 

Section 10.13     Claims Procedure. 

(a)     Filing a Claim for Benefits. If an Employee disputes the Committee’s decision with respect to
the Employee’s eligibility to become a Participant, if a Participant disputes the amount of contribution allocated to the Participant or the determination of his or her interest in the Trust, or if an Employee, a Participant or his or her
Beneficiary does not receive benefits to which he or she believes he or she is entitled, the person (the “Claimant”) may file a claim in writing with the Committee. 

(b)     Committee’s Notice of Decision. If the Committee totally or partially denies the claim, the
Committee will notify the Claimant in writing within 90 days after receiving the claim. If the Committee determines that special circumstances require an extension of time to issue the notice of decision, the Committee must furnish, prior to the end
of the initial 90-day period, a written extension notice. In no event may the extension exceed a period of 90 days from the end of the initial 90-day period. The
extension notice must indicate the special circumstances requiring an extension of time and the date by which the Plan expects to render a determination. 

  
 - 59 - 













 The written notice of decision will state the specific reason for denial of the claim and
make a specific reference to the Plan provisions on which the denial is based. It will describe any additional material the Claimant may need to submit to the Committee to have the claim approved, and will give the reasons the material is necessary.
In addition, the notice will explain the claim review procedure. 
 (c)     Anneal of Adverse Benefit
Determination. If the Claimant receives a notice that the claim has been denied, the Claimant, or his or her authorized representative, may appeal to the Committee to review the claim. The Claimant must submit a written request for review to
the Committee within 60 days after the date the written notice of denial of the claim is received. In connection with a request to review an adverse benefit determination, a Claimant, or his or her authorized representative, (1) may submit
written comments, documents, records, and other information relating to the claim for consideration by the Committee; and (2) will be provided, upon request and free of charge, reasonable access to, and copies of, all documents, records, and
other information relevant to the Claimant’s claim for benefits. The Committee’s review will take into account all comments, documents, records and other information submitted by the Claimant relating to the claim, without regard to
whether the information was submitted or considered in the initial benefit determination. 
 The Committee will notify a Claimant of the
Plan’s benefit determination on review within a reasonable period of time, but not later than 60 days after receipt of the Claimant’s request for review by the Plan, unless the Committee determines that special circumstances require an
extension of time for processing the review. If the Committee determines that an extension of time for processing is required, written notice of the extension will be furnished to the Claimant prior to the termination of the initial 60-day period. In no event will an extension exceed a period of 60 days from the end of the initial 60-day period. The extension notice will describe the special circumstances
that require an extension of the time and the date by which the Committee expects to render the determination on review. 
 In the case of
an adverse benefit determination on review, the written notice of determination will include the specific reason or reasons for the adverse determination, a reference to the specific Plan provisions on which the benefit determination is based, a
statement that the Claimant is entitled to receive, upon request and free of charge, reasonable access to, and copies of, all documents records and other information relevant to the Claimant’s claim for benefits, and a statement of the
Claimant’s right to bring an action under Section 502(a) of ERISA. 
 For purposes of this Subsection (c), a document, record or
other information will be considered “relevant” to a Claimant’s claim if the document, record or other information (i) was relied upon in making the benefit determination, (ii) was submitted, considered or generated in the
course of making the benefit determination, without regard to whether that document, record or other information was relied upon in making the benefit determination, and (iii) demonstrates compliance with the administrative processes and
safeguards required in making the benefit determination. The Committee’s decision is final and conclusive. 

  
 - 60 - 













 (d)     Legal Actions. No legal action may be brought in
court on a claim for benefits under the Plan after 180 days following the Committee’s decision on appeal (or 180 days following the expiration of the time to make an appeal if no appeal is made).

 (1)     Counsel advises are necessary or appropriate to assure
qualification of the Plan with appropriate provisions of the Code, or to comply with any other applicable law, governmental rules or regulations; 

(2)     Are advisable to make technical or clarifying changes to the Plan; 

(3)     The Trustees may require; or 

(4)     Are otherwise advisable or appropriate.

resolution of the Board of Directors of the Company authorizing the action. 
 (b)     Disposition of Assets on
Termination. Upon termination (but not partial termination) of the Plan, the Trustees will dispose of the assets of the Trust by (1) valuing the assets, (2) allocating the assets to the accounts of each Participant, and
(3) distributing to the Participants their nonforfeitable interest as soon as practicable following the termination in accordance with Article 5. 

Section 11.3     Merger or Consolidation. This Plan will not be merged or consolidated with, nor
may its assets or liabilities be transferred to, any other plan unless each Participant would receive a benefit immediately after the merger, consolidation or transfer (if the Plan then terminated) that is equal to or greater than the benefit he or
she would have been entitled to receive immediately before the merger, consolidation or transfer (if the Plan then terminated).

 ARTICLE 12 

DIRECT ROLLOVERS 

Section 12.1     Direct Rollovers. Notwithstanding any provision of the Plan to the contrary that
would otherwise limit a distributee’s election under this Article, a distributee may elect, at the time and in the manner prescribed by the Committee, to have any portion of an eligible rollover distribution paid directly to an eligible
retirement plan specified by the distributee in a direct rollover. 
 Section 12.2    
Definitions. 
 (a)     Eligible Rollover Distribution. An eligible rollover distribution shall
have the meaning set forth in Section 401(a)(31)(D) of the Code. Notwithstanding the foregoing, for distributions made prior to January 1, 2010, a distribution to a non-spouse Beneficiary will not
constitute an eligible rollover distribution unless the distribution is made during the year of the Participant’s death. 

(b)     Eligible Retirement Plan. An eligible retirement plan refers to any of the following entities,
provided that the entity accepts the distributee’s eligible rollover distribution: (i) an individual retirement account described in Section 408(a) of the Code, (ii) an individual retirement annuity described in
Section 408(b) of the Code, (iii) an annuity plan described in Section 403(a) of the Code, (iv) a qualified trust described in Section 401(a) of the Code, (v) an annuity contract described in Section 403(b) of the
Code, (vi) 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, or (vii) effective for distributions made after December 31,2007, and to the extent permitted by law, a Roth IRA. The definition of eligible retirement plan will also apply in
the case of an eligible rollover distribution to a surviving spouse, or to a spouse or former spouse who is the Alternate Payee under a Qualified Domestic Relations Order, as defined in Section 414(p) of the Code. In the case of an eligible
rollover distribution to a non-spouse Beneficiary, an eligible retirement plan is limited to an individual retirement account or an individual retirement annuity that is established for the purpose of
receiving the distribution on behalf of such Beneficiary, as described in Section 402(c)(11) of the Code. 

(c)     Distributee. A distributee includes a Participant or former Participant. In addition, the
Participant’s 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. Effective for distributions made after December 31, 2006, a distributee also includes a non-spouse Beneficiary,
subject to the limitations set forth in Subsections (a) and (b). 
 (d)     Direct Rollover. A direct
rollover is a payment by the Plan to the eligible retirement plan specified by the distributee.

and Trust are purely voluntary on the part of the Company. The Trust is the sole source of benefits and in no event is the Company liable or otherwise responsible for benefits. The Plan is binding upon the Company and all Participants under the
Plan, and upon their respective heirs, executors, administrators, successors and assigns, and upon all persons having or claiming to have any interest of any kind or nature in or under the Plan or the Trust. 

Section 13.4     Spendthrift Clause. 

(a)     In General. Except as provided in Subsections (b) and (c), or pursuant to an order of a court of
competent jurisdiction to the contrary, none of the payments, benefits or rights of any Participant, Beneficiary, Prospective Beneficiary or Alternate Payee will be subject to any claim of any creditor. In particular, to the fullest extent permitted
by law, all such payments, benefits and rights will be free from attachment, garnishment, trustee’s process, or any other legal or equitable process available to any creditor of such Participant, Beneficiary, Prospective Beneficiary or
Alternate Payee. Except as provided in Subsection (b), no person entitled to any payment, benefit or right under the Plan will have the right to alienate, anticipate, commute, pledge, encumber or assign any of the payments, benefits or rights which
he may expect to receive, contingently or otherwise, under the Plan. 
 (b)     Exceptions. The following
will not be precluded by the operation of Subsection (a): 
 (1)     the withholding of income taxes from
distributions (whether by legal mandate or by election of the prospective distributee) and transmittal of the amounts so withheld to appropriate tax collection authorities; 

(2)     any arrangement for recovery by the Plan of overpayments of benefits previously made to or for the
benefit of the Participant or other person with respect to whom the arrangement applies; 
 (3)
    transfer of any eligible rollover distribution from the Plan to any eligible retirement plan as described in Article 12; 

  
 - 65 - 













 (4)    direct deposit arrangements with respect to
benefits if the direct deposits authorized by the arrangement is to an account of the payee (or a joint account of the payee and his spouse) at a bank or other financial institution; 

(5)     any assignment or alienation of benefits in pay status to the extent that the assignment or
alienation: (i) is voluntary and revocable, (ii) is not for the purpose of, nor has the effect of, defraying Plan administration costs; and (iii) does not, when combined with all other such assignments in the aggregate, exceed 10% of
any benefit payment; 
 (6)     any assignment to the Company if the assignment is revocable at any time,
and the Company files with the Committee a written acknowledgment meeting the requirements of Treasury Regulation Section 1.401(a)-13(e)(2) (or a successor regulation of similar purpose); and 

(7)     the enforcement of a federal tax levy made pursuant to Code Section 6331 or the collection by
the United States on a judgment resulting from an unpaid tax assessment. 
 (c)     Applicability of a
Qualified Domestic Relations Order. Compliance with the provisions and conditions of any Qualified Domestic Relations Order will not be deemed a violation of the provisions of Subsection (a). 

Section 13.5     Qualified Domestic Relations Order. 

(a)     In General. “Qualified Domestic Relations Order” has the same meaning as it has in
Code Section 414(p). 
 The Committee will establish a written procedure to determine the qualified status of domestic relations orders
and to administer distributions under such qualified orders. Upon receipt of a domestic relations order made pursuant to state law the Committee will: 

(1)     promptly notify the Participant and any other Alternate Payee, as defined by Code
Section 414(p)(8), of the receipt of the order and the Plan’s procedures for determining its qualified status; 

(2)     determine within a reasonable period after its receipt whether the order is a Qualified Domestic
Relations Order, and notify the Participant and any other Alternate Payee of the determination; and 
 (3)
    segregate in a separate account in the Plan the amounts which would have been payable to the Alternate Payee designated in the order during the period of determination specified in paragraph (2), if the order has been
determined to be a Qualified Domestic Relations Order. 
 If the Committee determines that the order is a Qualified Domestic Relations
Order, it will then direct the Trustees to comply with the order and will release the amounts held in the segregated account to the Alternate Payee designated in the order. 

  
 - 66 - 













 To the extent provided under a Qualified Domestic Relations Order, a Participant’s
former spouse will be treated as the spouse for all purposes under the Plan. The Committee may direct that distributions to an Alternate Payee pursuant to a Qualified Domestic Relations Order commence prior to the Participant’s earliest
retirement age (within the meaning of Section 414(p)(4)(B) of the Code). The Alternate Payee will be paid his or her benefit in a lump-sum payment notwithstanding the value of such lump-sum payment, unless the Qualified Domestic Relations Order specifies a different manner of payment permitted by the Plan; the Alternate Payee will not be required to consent to such lump-sum payment. 
 Distributions are permitted to be made under a Qualified Domestic Relations Order,
regardless of whether the affected Participant has met the criteria required for a distribution to the Participant under the Plan. 

(b)     Pre-1985 Domestic Relations Orders. A domestic relations
order entered before January 1, 1985 will be treated as a Qualified Domestic Relations Order if payment of benefits under the order has commenced as of that date, and a domestic relations order may be treated as a Qualified Domestic Relations
Order if payment of benefits has not commenced as of that date, even though the order does not satisfy the requirements of Code Section 414(p). 

Section 13.6     Notice to Employees. Notice of the existence and the provisions of the Plan are
communicated by the Committee to all individuals who are or who become Participants. 
 Section 13.7    
No Employment Rights Created. The creation and maintenance of the Plan does not confer on any Employee any right to continued employment, and all Employees remain subject to discharge to the same extent as if the Plan had never been
established. 
 Section 13.8     Diversion from Employees Prohibited. Except as otherwise
permitted by law, no part of the corpus or income of any trust fund maintained pursuant to the Plan or of any funds contributed to any such trust fund may be used for, or diverted to purposes other than the exclusive benefit of Participants or their
Beneficiaries. In the event the Company makes an excessive contribution under a mistake of fact pursuant to Section 403(c)(2)(A) of ERISA, the Company may demand repayment of the excess contribution at any time within one year following the
time of payment and the Trustees will return the excess amount to the Company within the one year period. Earnings of the Plan attributable to the excess contributions may not be returned to the Company but any losses attributable thereto must
reduce the amount returned. Contributions made by the Company are conditioned on the deductibility of the contributions under Section 404 of the Code and will be returned to the Company, to the extent disallowed, within one year after the
disallowance of the deduction. 
 Section 13.9     Right to Judicial Accounting. Nothing
contained in the Plan may be construed as depriving the Trustees of the right to have a judicial settlement of their accounts. Upon any proceeding by the Trustees for a judicial settlement or for instructions, the only necessary party thereto in
addition to the Trustees is the Company. None of the Participants or other Beneficiaries of the Plan have any right to compel an accounting, judicial or otherwise, by 

  
 - 67 - 













 the Trustees, and all parties will be bound with respect to all accounts submitted by the Trustees to the
Company as provided by the Plan and Trust. 
 Section 13.10     Transfer of Funds to Another
Plan. 
 (a)     In General. If (1) a Participant under the Plan becomes a participant under
any other plan qualified under Section 401(a) of the Code, (2) the trust under the other plan is exempt from tax under Section 501(a) of the Code, and (3) the other plan provides that amounts may be transferred to it from other
qualified plans in which the Employee has been eligible to participate, then the Participant may elect, subject to approval by the Committee, to transfer such amount from the Plan to such other plan to be held in trust and invested in accordance
with that plan. In the case of a transfer to another plan made under this Section, the entire amount available for transfer is transferred as soon as administratively feasible. 

(b)     Transfer of Assets and Liabilities for Certain Former Eligible Employees Who Continue Employment with the
Company. This Section 13.10(b) shall apply if a Participant ceases to be an Eligible Employee in connection with a change in employment which results in such Participant commencing participation in the Union Plan (as defined in
Section 2.2(a)). 
 (1)     If a Participant becomes a participant in the Union Plan, there shall be
transferred from this Plan to the Union Plan the entire accrued benefit of the Participant, and assets equal in value to the Participant’s accounts under this Plan on the date as of which the accrued benefit is transferred. The transfer of the
entire accrued benefit of the Participant and the Plan assets shall occur as soon as administratively feasible following the date on which the Participant ceases to be an Eligible Employee. 

(2)     If an Employee is reinstated as a Participant in this Plan, any accrued benefit previously
transferred from this Plan to the Union Plan shall be transferred from the Union Plan to this Plan, together with assets equal in value to the accounts of the participant under the Union Plan. 

(3)     Any transfer of assets from or to this Plan to or from the Union Plan pursuant to this
Section 13.10(b) shall comply with the requirements of Internal Revenue Code Section 414 and applicable Treasury Department Regulations, rulings and releases thereunder. 

Section 13.11     Forfeiture on Account of Inability to Locate Participant or Beneficiary.
Notwithstanding any other provision of the Plan, if a benefit becomes payable to a Participant or to his or her Beneficiary and if the Company, after all reasonable efforts, is unable to locate the Participant or Beneficiary, the benefit payable to
the Participant or Beneficiary is forfeited. 
 If a benefit is forfeited due to the Company’s inability to locate a Participant or
Beneficiary, and the Participant or his or her Beneficiary subsequently makes a claim for the benefit, the benefit is then reinstated. Any reinstatement of forfeited amounts under this Section 

  
 - 68 - 













 is first made from forfeitures, if any, occurring during the Plan Year in which the reinstatement occurs,
and then, if necessary, by an additional contribution by the Company. 
 Section 13.12     Incapacity
of Person Entitled to Payment. If any person entitled to receive any benefits under the Plan (“distributee”) is, in the judgment of the Committee, legally, physically, or mentally incapable of personally caring for his or her
affairs, unless prior claim has been made by a duly qualified guardian or other legal representative, the Committee may instruct the Trustees to make distribution to the other person, persons, or institutions as, in the judgment of the Committee,
maintains, has custody of, or is otherwise responsible for the distributee. Any such payment is a payment for the distributee’s account and is a complete discharge of any liability of the Plan therefor. 

Section 13.13     Adoption of Plan by Organization Under Common Control. With the consent of the
Board of Directors of National, the Plan may be adopted by any Organization Under Common Control with National for the benefit of all or a limited group of the organization’s Employees as specified in an agreement to adopt the Plan executed by
the organization and the Board of Directors of the Company. If an Organization Under Common Control adopts the Plan, the term “Company” also refers to the organization. 

Section 13.14     Rules Relating to the Correction of Administrative Errors. The Committee may
take any actions it considers necessary and appropriate to remedy any inequity that results from incorrect information received or communicated in good faith, or as a consequence of an administrative or operational error. The Committee’s
actions may include, but are not limited to: (i) taking any action permitted under the employee plans compliance resolution system of the Internal Revenue Service, any asset management or fiduciary conduct error correction program available
through the Department of Labor, any similar correction program instituted by the Internal Revenue Service, Department of Labor or other administrative agency, (ii) reallocation of Plan assets, (iii) adjustments in amounts of future
payments to Participants, Beneficiaries or Alternate Payees, and (iv) institution and prosecution of actions to recover benefit payments made in error or on the basis of incorrect or incomplete information.

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

 2016 RESTATEMENT 

NATIONAL FUEL GAS COMPANY TAX-DEFERRED SAVINGS PLAN 

FOR NON-UNION EMPLOYEES 

AMENDMENT NO. 6 
 Under
Section 11.1 of the National Fuel Gas Company Tax-Deferred Savings Plan for Non-Union Employees (the “Plan”), National Fuel Gas Company (the
“Company”) reserves the right to modify or amend the Plan. This Amendment No. 6 of the Plan (the “Amendment”) is adopted to make certain changes to the adjustment dates that determine how participant elections and company
contributions are implemented and calculated and to make certain other clarifications. The changes herein are effective February 1, 2020. 

This Amendment supersedes the provisions of the Plan to the extent those provisions are inconsistent with the provisions of this Amendment.

 The Plan is amended in the following respects: 

1.     Section 1.3(k) (definition of “Adjustment Date”) is amended to read in its entirety as follows: 

(k)     Adjustment Date means, effective for periods on or before February 1, 2020, February 1 and
August 1 of each Plan Year, or any other date or dates established by the Committee in advance of any Plan Year on which a Participant may change his or her contribution percentage. Notwithstanding the preceding sentence and solely for purposes
of Section 3 .1, in the case of a Participant whose Base Salary is reduced during the course of a Plan Year as a result of the Participant electing unpaid leave under the Family & Medical Leave Act of 1993, as a result of a workers
compensation benefit or as a result of the enforcement of the Company’s sick pay policy, as it may be in effect from time to time, the Committee may declare in a nondiscriminatory manner that an additional Adjustment Date will have occurred for
such Participant as of the date such Participant’s Base Salary is reduced. The intent of this provision is to prevent a violation of Section 415 of the Code due to an unexpected decrease in Base Salary. 

2.     Section 3.1 (“Salary Reduction Contributions”) is amended by replacing existing subsections (a) and (b) thereof
with the following: 
 (a)     In General. Effective August 1, 2002 and thereafter,
each Participant, in accordance with Subsection (b) may elect to contribute a percentage amount, expressed in one percent increments, equal to at least 2% of “Base Salary” and not to exceed 50% of “Base Salary”, as defined
in Section 3.8. Effective February 1, 2016, each Participant, in accordance with Subsection (b) may elect to contribute a percentage amount, expressed in one percent increments, equal to at least 2% of “Base Salary” and not
to exceed 60% of “Base Salary”, as defined in Section 3.8. 

  
 1 













 For the purposes of the Plan, “Salary Reduction Contribution”
means a contribution made pursuant to a Participant’s election under this Subsection. Salary Reduction Contributions under this Subsection will be made by reducing a Participant’s Base Salary throughout the period during which his or her
election under this Section remains in effect. Effective before February 1, 2020, the amount of each Participant’s Salary Reduction Contributions was recalculated only as of each Adjustment Date, based on the Participant’s then
current Base Salary. Effective starting on February 1, 2020, the amount of each Participant’s Salary Reduction Contributions is based on the Participant’s Base Salary paid during the period for which his or her election under this
Section remains in effect. 
 All Salary Reduction Contributions are intended to qualify as “employer
contributions” under Section 401(k) of the Code. 
 Effective as of July 1, 2005, individuals who are employed
as “Customer Support Representative I” or “Customer Support Representative II” are not eligible to make Salary Reduction Contributions. 

(b)     Salary Reduction Contribution Elections. The Committee may prescribe uniform rules of
general application concerning all elections under this Section, including the effective date of any elections, or changes to elections, made by Participants under this Section. The rules also may limit the amount of Salary Reduction Contributions
or the frequency of any changes to elections made by Participants. All elections under this Section will remain in effect until modified or discontinued by the Participant in accordance with the rules established by the Committee. In furtherance of
the preceding sentence and solely for purposes of this Section 3.1, in the case of a Participant whose Base Salary is reduced as a result of the Participant electing unpaid leave under the Family & Medical Leave Act of 1993, as a
result of a workers compensation benefit or as a result of the enforcement of the Company’s sick pay policy, as it may be in effect from time to time, the Committee may in a nondiscriminatory manner adjust a Participant’s Salary Reduction
Contribution as of the day such Participant’s Base Salary is reduced in order to prevent a violation of Section 415 of the Code due to an unexpected decrease in Base Salary. 

For a Participant who becomes an Eligible Employee in connection with a change in employment which results in such Employee
ceasing to participate in the Union Plan (as defined in Section 2.2(a)), such Employee’s contribution election then in effect under the Union Plan (if any) will continue to be applicable on the same terms as then in effect, until modified
or discontinued by the Participant in accordance with the rules established by the Committee, but such contributions will be made to this Plan following such change in employment. 

For Participants whose classification as an Eligible Employee changes, for example, changing from being Group I Employees to
Group II Employees, the respective contribution elections then in effect (if any) will continue to be applicable on the same terms as then in effect, until modified or discontinued by the Participant in accordance


  
 2 













 
with the rules established by the Committee. 
 The Committee must
provide a reasonable period at least once each calendar year for a Participant to commence Salary Reduction Contributions or to modify the amount of his or her Salary Reduction Contributions. Furthermore, Participants, before any payroll period or
other payment of Base Salary, may elect to discontinue Salary Reduction Contributions. A discontinuance of Salary Reduction Contributions will remain in effect until a new election is made in accordance with the provisions of this Subsection. A
Participant may not make retroactive elections under this Section. 
 3.     Section 3.2 (“Company Contributions”) is
amended to read in its entirety as follows: 
 Section 3.2     Company Contributions 

 (a)     For each calendar month commencing February 1, 2014, the Company Contribution to
the Plan will be as follows: 3% of the Company Contribution Compensation for that month for each Post-2003 Qualified Participant who has been credited with fewer than six Years of Company Contribution Service; and 4% of the Company Contribution
Compensation for that month for each Post-2003 Qualified Participant who has been credited with at least six Years of Company Contribution Service. For purposes of this Subsection, a Participant’s Years of Company Contribution Service is
determined as follows: (i) for periods before February 1, 2020, as of the most recent Adjustment Date, (ii) effective February 1, 2020, as of the first day of the applicable month. 

(b)     For purposes of this Section and Section 3.7(d), Company Contribution Compensation for
a month is: (I) for periods before February 1, 2020, 1112 of a Post-2003 Participant’s regular annual base compensation (salary or hourly pay) as of the most recent Adjustment Date, or (II) effective February 1, 2020, the
Post-2003 Participant’s regular base compensation (salary or hourly pay) as of the first day of such month. Notwithstanding the preceding sentence, Company Contribution Compensation will specifically include (1) elective contributions made
by a Company on the Employee’s behalf pursuant to a cash or deferred arrangement described in Section 401(k) of the Code or an election under Section 125 or 132(f)(4) of the Code, and (2) (i) lump sum compensation paid to supervisory
employees of National Fuel Resources, Inc., National Fuel Gas Supply Corporation, National Fuel Gas Distribution Corporation or Horizon Energy Development, Inc., that is designated for payroll and human resources purposes as “lump sum pay”
in lieu of a base increase, (ii) discretionary bonuses paid to salaried employees of National Fuel Resources, Inc., before February 1, 2014, (iii) bonuses paid under the Seneca Resources Corporation Annual Cash Bonus Program before
February 1, 2014, (iv) Executive Annual Cash Incentive Program (EACIP) payments, (v) Annual At Risk Compensation Incentive Plan (AARCIP) payments, and (vi) annual bonuses paid to officers who are
“non-16b officers” at the time the bonus is paid. Company Contribution Compensation will specifically exclude any other compensation amount not described in this Section 3 .2(b).

 The Company Contribution Compensation of a Post-2003 Participant taken into
account in any Plan Year beginning after December 31, 2002, will not exceed $200,000. The $200,000 limit will be adjusted for cost-of-living increases in accordance
with Section 40l(a)(l7) of the Code. The cost-of-living adjustment in effect for a calendar year applies to Company Contribution Compensation for the Plan Year that
begins with or within such calendar year. 
 (c)     Effective before February 1, 2020, and
notwithstanding the foregoing, for a Participant who became an Eligible Employee in connection with a change in employment which results in such Employee ceasing to participate in the Union Plan, such Employee’s Company Contributions under the
Union Plan (if any) continued on the same terms as in effect on the most recent Adjustment Date, until the next Adjustment Date, but such contributions were made to this Plan following such change in employment. 

4.     Section 3.3 (“Matching Contributions”) is amended to read in its entirety as follows: 

Section 3.3     Matching Contributions. For each payroll period during
which a Participant (other than individuals who are employed as a “Customer Support Representative I” or “Customer Support Representative II”) makes Salary Reduction Contributions in accordance with Section 3 .1, the Company
will contribute to the Plan for the benefit of the Participant in an amount equal to the Participant’s Base Salary for such payroll period, multiplied by the Matching Contribution Percentage determined in accordance with the tables that follow
(“Matching Contributions”). For purposes of calculating the Matching Contributions for any payroll period, the following rules apply: 

(a)     Effective before February 1, 2020, Base Salary for the applicable period was the
Participant’s Base Salary in effect on the immediately preceding Adjustment Date. Effective for pay dates on or after February 1, 2020, Base Salary is the Participant’s Base Salary paid during the applicable period for which Matching
Contributions are made. 
 (b)     The Matching Contribution Percentage will be determined under
the following tables with reference to the rate of Salary Reduction Contributions under Section 3.1 in effect during the period for which Matching Contributions are made; provided, however, that for periods before February 1, 2020: (i) for
Participants whose classification as an Eligible Employee changed, for example, changing from being Group I Employees to Group II Employees, the Matching Contribution Percentage determined under the respective table as of the most recent Adjustment
Date continued to be applicable following such classification change, until the next Adjustment Date; and (ii) for a Participant who becomes became an Eligible Employee in connection with a change in employment which resulted in such Employee
ceasing to participate in the Union Plan, such Employee’s Matching Contributions under the Union Plan (if any) were discontinued and Matching Contributions were made to this Plan following such change in employment, based on the contribution
election under the Union Plan (if any) and the Participant’s Years of Service as of the most recent Adjustment Date with the Matching

Contribution Percentage determined under the respective table under the Union Plan as of the most recent Adjustment Date, until the next Adjustment Date.

 5.     Section 3.8 (“Base Salary”) is clarified and amended to read in its entirety as
follows: 
 Section 3.8     Base Salary. The term “Base Salary” for any Plan Year means: 

 

	 	(a)	 Effective for pay dates before February 1, 2020 and, for Participants employed by Seneca Resources
Company, LLC or National Fuel Resources, Inc., pay dates on or after February 1, 2020, the Participant’s basic compensation for a payroll period, excluding compensation under the National Fuel Gas Company Deferred Compensation Plan, when
deferred and when received, any amounts the 



  
 5 














	 	
Participant receives as overtime pay, commissions or other special pay, fees, bonuses or allowances, but including salary contribution payments made by the Company on account of sickness or
accident. Notwithstanding the preceding sentence, for individuals whose established normal work schedule includes regularly scheduled overtime (for example, three 12-hour shifts followed by four 12-hour shifts during a two-week payroll period), basic compensation for the payroll period is deemed to include such regularly scheduled overtime pay (but no other overtime
pay other than regularly scheduled overtime pay). 

  

	 	(b)	 Effective for pay dates on or after February 1, 2020 for Participants employed by a Company other than
Seneca Resources Company, LLC or National Fuel Resources, Inc., the term “Base Salary” means the Participant’s basic compensation for a payroll period including overtime pay, shift premiums, holiday premiums, standby pay, and
exception rate pay (i.e., pay rate adjustments for work performed in a different position than the Participant’s defined position). 



Notwithstanding the foregoing, “Base Salary” includes contributions made by the Company pursuant to a salary reduction agreement that
are not includable in the Participant’s gross income under Section 125, 402(e)(3), 402(h) or 403(b) of the Code and, effective for Plan Years beginning on or after January 1, 2001, Section 132(f)(4) of the Code. 

The Base Salary of each Participant taken into account in determining allocations for any Plan Year beginning after December 31, 2001,
shall not exceed $200,000, as adjusted for cost-of-living increases in accordance with Section 401 (a)(17)(B) of the Code. The cost-of-living adjustment in effect for a calendar year applies to Base Salary for the determination period that begins with or within such calendar year. If a Participant’s Base Salary is determined
over a period of time that is shorter than 12-months, then the $200,000 limit, as adjusted, will be prorated for the number of full calendar months in the period. 

6.     In all other respects, the Plan remains unchanged.
