 Exhibit 4.3 
 THRIFT PLAN FOR EMPLOYEES

replaces all prior documents and amendments, and is effective as of the Effective Date determined by the Board of Directors of ONEOK, Inc. and its subsidiaries. 
 The purposes of the Plan and the Trust established thereunder are to provide for deferred compensation and benefits for eligible employees through a qualified profit-sharing plan and, in part, with respect to the
investment in securities of ONEOK, Inc., through an employee stock ownership plan which constitutes a qualified stock bonus plan. The Plan is intended in all respects to be qualified under the Internal Revenue Code of 1986, as amended.

maintained for a Participant pursuant to this Plan. A Participant’s Accrued Benefit from Company contributions as of any applicable date is the excess, if any, of the Accrued Benefit of such Participant as of such date over the Accrued Benefit

and to the extent permitted by Section 401(k) of the Code, calculate such ratios by adding to the 401(k) Contribution for such Employee the Matching Contribution paid for the benefit of such Employee and qualified nonelective contributions
(within the meaning of Code Section 401(m)(4)(C)).

contributed or deferred. Provided, that any reduction in salary elected and deferred by the Participant under the cash or deferred arrangement of Article III
of the Plan or under Code Sections 125, 132(f)(4), 402(e)(8) and 457 pursuant to the employee benefit plans of the Company shall be included in determining compensation hereunder. For purposes of this definition incentive compensation shall be
treated as paid to a Participant at the time of actual payment. Provided, further, that the annual compensation of each Participant taken into account under this Plan for any year shall not exceed two hundred thousand dollars ($200,000) in the years
beginning after December 31, 1988, and before January 1, 1994, (such two hundred thousand dollars ($200,000) amount to be adjusted to reflect increases in the cost-of-living in accordance with Code Sections 401(a)(17) and 415(d)). In
addition to other applicable limitations set forth in the Plan, and notwithstanding any other provision of the Plan to the contrary, for Plan Years beginning on or after January 1, 1994, the annual compensation of each Employee taken into
account under the Plan shall not exceed the OBRA ‘93 annual compensation limit. The OBRA ‘93 annual compensation limit is $150,000, as adjusted by the Commissioner of the Internal Revenue Service for increases in the cost-of-living in
accordance with Code Section 401(a)(17)(B). The cost-of-living adjustment in effect for a calendar year applies to any period, not exceeding 12 months, over which compensation is determined (determination period) beginning in such calendar
year. If a determination period consists of fewer than 12 months, the OBRA ‘93 annual compensation limit will be multiplied by a fraction, the numerator of which is the number of months in the determination period, and the denominator of which
is 12. For Plan Years beginning on or after January 1, 1994, any reference in this Plan to the limitation under Section 401(a)(17) of the Code shall mean the OBRA ‘93 annual compensation limit set forth in this provision. If
compensation for any prior determination period is taken into account in determining an Employee’s benefits accruing in the current Plan Year, the compensation for that prior determination period is subject to the OBRA ‘93 annual
compensation limit in effect for that prior determination period. For this purpose, for determination periods beginning before the first day of the first Plan Year beginning on or after January 1, 1994, the OBRA ‘93 annual compensation
limit is one hundred fifty thousand dollars ($150,000). 
 Provided, further, that notwithstanding anything to the contrary contained in the Plan, any
payment or distribution made to an Employee pursuant to the ONEOK Energy Marketing & Trading Group Bonus Plan shall be excluded from, and not considered as Compensation of such Employee under this Plan. 
 Provided, further, that the annual compensation of each Participant taken into account under Plan for any year beginning after December 31, 2001 shall not exceed
$200,000 and such $200,000 amount shall be adjusted to reflect increases in the cost-of-living in accordance with Code Sections 401(a)(17) and 415(d). 
 If
any individual is a member of the family of such Participant, such individual shall not be considered a separate Employee; and any compensation paid to such individual shall be treated as if it were paid to (or on behalf of) such Participant, with
the term “family” for such purpose meaning the spouse of the Participant and any lineal descendants of the Participant who have not attained age 19 before the close of the year. Provided, that effective for years beginning after
December 31, 1996, the family aggregation rules of Code section 414(q)(6) repealed by the Small Business Job Protection Act of 1996, shall have no application to the Plan.

of this Plan shall include “Adjusted Total Compensation” and “Annual Compensation”, defined as follows: 
 “Adjusted Total

 “Annual Compensation” shall mean the base salary or wage paid to an active Bargaining Unit Participant

Employee under any other deferred compensation or welfare plan. Provided, that on and after July 20, 2003, “Annual Compensation” for any Group B Bargaining Unit Employee who is represented by Local 304 and Local 1523 of the
International Brotherhood of Electrical Workers shall include the base salary or wage paid to such an active Group B Bargaining Unit Employee during a calendar year by the Company plus overtime, shift differential, call out, call out 7th day, FLSA OT ADJ, meal not eaten, OT double time, OT straight time, OT time and one-half, overtime, standby half pay, standby quarter pay and all earning
elements included in compensation for purposes of the Plan prior to such date. Annual Compensation shall be such amount prior to any payroll reduction for a Participant Reduction in Compensation or amounts excludible from the Employee’s gross
income under Code Sections 125, 132(f)(4), 402(e)(8) and 457. 
 The Annual Compensation and Adjusted Total Compensation of each active Bargaining Unit
Participant taken into account for determining all benefits provided under the Plan for any Plan Year beginning on or after January 1, 1997, shall not exceed $160,000 as adjusted for increases in the cost-of-living in accordance with Code
Section 401(a)(17)(B). The cost-of-living adjustment in effect for a calendar year applies to any determination period beginning in such calendar year. 
 Provided, further, that the annual compensation of each Participant taken into account under Plan for any year beginning after December 31, 2001 shall not exceed $200,000 and such $200,000 amount shall be adjusted to reflect increases
in the cost-of-living in accordance with Code Sections 401(a)(17) and 415(d). 
 In determining the compensation of any Employee for purposes of this
limitation, the rules of Section 414(q)(6) of the Code shall apply, except in applying such rules, the term “family” shall include only the spouse of the Employee and any lineal descendants of the Employee who have not attained age 19
before the close of the year. If, as a result of the application of such rules, the adjusted $160,000 limitation is exceeded, then the limitation shall be prorated among the affected individuals in proportion to each such individual’s
compensation as determined under this Section before application of this limitation. Provided, that effective for years beginning after December 31, 1996, the family aggregation rules of Code Section 414(q)(6) repealed by the Small
Business Job Protection Act of 1996, shall have no application to the Plan. 
 If a determination period consists of fewer than 8 months, the Annual
Compensation and Adjusted Total Compensation limit is an amount equal to the otherwise applicable Annual Compensation and Adjusted Total Compensation limit multiplied by a fraction, the numerator of which is the number of months in the short
determination period, and the denominator of which is 12.

 C. Increase in Compensation Limit. For any Plan Year beginning after December 31, 2001, the annual
compensation of each Participant taken into account in determining allocations shall not exceed Two Hundred Thousand Dollars ($200,000), as adjusted for cost-of-living increases in accordance with Code Section 401(a)(17)(B). Annual Compensation
means compensation during the Plan Year or such other consecutive 12-month period over which compensation is otherwise determined under the Plan (the determination period). The cost-of-living adjustment in effect for a calendar year applies to

	3.	Participation Voluntary 

 Participation in the Plan by eligible

	4.	Confirmation of Participation 

 Each Employee at the time of
becoming a Participant in the Plan shall be given a copy of the Plan as effective at that time, and as a condition of participation he/she shall sign an instrument in such form as prescribed by the Committee evidencing the fact that he/she accepts

	7.	Breaks in Service 

 If an Employee who has not satisfied the
eligibility requirements of the Plan and whose employee relationship with the Company has been terminated, is subsequently reemployed, he/she shall again be eligible to participate in the Plan, and to commence to participate in accordance with
paragraphs 1. and 2. of this Article II. Notwithstanding the foregoing eligibility provisions, or any other provisions of this Plan, an Employee’s prior Years of Service shall always be considered in determining the satisfaction of the
eligibility requirements if such termination period is not a period of consecutive One (1)-year Breaks in Service which equals or exceeds the greater of five (5), or the aggregate number of Years of Service before such termination period. If any
Years of Service are not

not exceeding the hours described in subparagraphs A. and B., below, by an Employee for any period by reason of the pregnancy of the Employee; by reason of the birth of a child of the Employee; by reason of the placement of a child with the Employee
in connection with the adoption of such child by the Employee; or for the purpose of caring for such child for a period beginning immediately following such birth or placement shall be treated as Hours of Service, solely for purposes of determining
whether a One (1)-year Break in Service has occurred with respect to Years of Service for purpose of eligibility for participation in this Plan. The Hours of Service described in this paragraph 8. are: 
 A. the Hours of Service which otherwise would normally have been credited to such Employee but for such absence, or

the total number of hours treated as Hours of Service under this paragraph 8. shall not exceed five hundred one (501) hours. 
 Provided, that no credit
will be given pursuant to this paragraph 8. unless the individual furnishes to the Committee such timely information as it may reasonably require to establish that the absence from work is for reasons referred to hereinabove, and the number of days
for which there was such absence. 
 The hours described in this paragraph 8. shall be treated as Hours of Service only in the year in which the absence from
work begins, if an Employee would be prevented from incurring a One (1) year Break in Service in such year solely because the period of absence is treated as Hours of Service as hereinabove provided; or in any case, in the immediately following
year. For purposes of application of the foregoing rules in this paragraph 8. the term “year” means the twelve (12) month period beginning on the first day of employment with the Company and each anniversary thereof.

Board of Directors, or the Committee at the Board of Directors’ direction, may determine on a uniform and nondiscriminatory basis, in accordance with
any agreement to which the Company shall be a party, or by which it shall be bound, and in a manner not inconsistent with law, whether employment with such other corporation or entity preceding such transaction or the Company’s acquisition of
stock of, or property from it, shall be deemed to be employment for eligibility purposes under this Plan; provided, that the determination of deemed service for eligibility or similar determinations in any particular instance of the acquisition of
stock or assets by the Company pursuant to the foregoing provisions of this paragraph 9., shall not be effective or control with respect to the employees of any other corporation in any prior or subsequent acquisition of stock or assets of another
corporation by the Company.

 ARTICLE III. 
 CONTRIBUTIONS FOR PARTICIPANT 401(k) SALARY REDUCTIONS 
 PARAGRAPH 
  

	1.	Company 401(k) Contributions 

 The Company shall contribute to the
Trust for each Plan Year, that portion of the Net Earnings of the Company for that year equal to the amount of the Reduction in Compensation elected by each Participant, and ESOP Dividend Distribution/Additional Deferral Contribution elected and
agreed to and deemed elected by each Participant pursuant to paragraphs 2. and 3. of this Article III, to the extent provided therein. Such contributions shall be the Company’s 401(k) Contribution for the Participant 
  

	2.	Cash or Deferral Election 

 A. Non-Bargaining Unit
Participants. 
  

	 	1.	In Plan Years prior to January 1, 2005, each Employee who is a Non-Bargaining Unit Participant in this Plan may elect a Reduction in Compensation in an amount not in excess of
the lesser of fourteen percent (14%) of his/her Compensation or the limitation on exclusion of elective deferrals for his/her taxable year, provided in Code Section 402(g), subject to applicable cost-of-living adjustment thereunder, or as
provided in any successor provision of the federal tax. 

 In Plan Years beginning on or after January 1, 2005, each
Employee who is a Non-Bargaining Unit Participant in this Plan may elect a Reduction in Compensation in an amount not in excess of twenty-four percent (24%) of his/her Compensation or the limitation on exclusion of elective deferrals for
his/her taxable year, provided in Code Section 402(g), subject to applicable cost-of-living adjustment thereunder, or as provided in any successor provision of the federal tax law. 
 The amount of such Reduction in Compensation shall be deferred and become the Company’s 401(k) Contribution for such Participant; provided, that to
the extent an elected Reduction in Compensation of a Highly Compensated Employee causes the limitations of paragraph 3. or 7. of Article VIII to be exceeded, the election shall not become effective for the excess amount and it shall be paid to the
Highly Compensated Employee in cash. If necessary to meet the limitations of paragraphs 2., 3., or 7. of Article VIII, a Non-Bargaining Unit Participant’s Reduction in Compensation, and the Company’s 401(k) Contribution shall be reduced in
the manner determined by the Committee, and may include, without limitation, reducing the percentage of highest elected Reductions in Compensation of Non-Bargaining Unit Participants then in effect until such limitations are not exceeded. In case
the amount and percentage be so reduced, such reduction shall be to the next lower full percentile below the permissible limitation percentage, and shall remain in effect until the next succeeding Designation Date, subject to any further adjustment
necessary to meet such limitations under paragraphs 2., 3., or 7. of Article VIII. 
  

 -19- 








 Notwithstanding any other terms or provisions of the Plan, for Plan Years commencing prior to
January 1, 2005, the total contributions which a Non-Bargaining Unit Participant may make by Reduction in Compensation and After-Tax Deposits shall not exceed eighteen percent (18%) of his/her Compensation. The limitation provided in this
paragraph shall not apply in Plan Years beginning on and after January 1, 2005.

annual additions, the dollar limit on Elective Deferrals Under Code Section 402(g) (not counting Catch-Up Contributions) and the limit imposed on the actual deferral percentage (ADP) test under Code Section 401(k)(3). Catch-Up
Contributions for a Participant for a taxable year may not exceed (1) the dollar limit on Catch-Up Contributions under Code Section 414(v)(2)(B)(I) for the taxable year or (2) when added to other Elective Deferrals, 75 percent of the
Participant’s Compensation for the taxable year. 

  

	 	3.	Each Participant in this Plan may elect a Reduction in Compensation by signing and filing with the Committee a written election and agreement in the form specified and furnished to
such Participant by the Committee and by making such election by telephone voice response system or internet in accordance with such rules and regulations as the committee may prescribe. 

  

	 	4.	Participant elections of Reduction in Compensation shall specify the whole percentage of the Participant’s Compensation which such Participant elects not to receive in cash and
to defer as his/her Reduction in Compensation. Elections by Non-Bargaining Unit Participants shall be stated in full percentiles of the Participant’s Compensation. 

  

	 	5.	A Non-Bargaining Unit Participant’s election of a Reduction in Compensation in the Plan after the January 1, 1999, effective date of the Plan, as merged with the KGS
401(k) Thrift Plan, shall be effective as of the dates of commencement of participation specified in paragraph 2. of Article II; provided, that any Non-Bargaining Unit Employee who does not commence participation on or before the Designation Date
next following his/her initial date of eligibility may only elect a Reduction in Compensation to be effective as of a subsequent Designation Date. 

  

	 	6.	 The Reduction in Compensation elected by a Non-Bargaining Unit Participant shall remain in effect until changed by such Participant’s delivery of a change of
election in the manner provided herein. A Non-Bargaining Unit Participant may change his/her Reduction in Compensation only on a Designation Date. A Non- Bargaining Unit Participant’s change of 



  

 -20- 









	 	 
election may designate a different percentage of Reduction in Compensation, subject to the terms and conditions of the Plan; and may state that such
Participant elects no Reduction in Compensation and deferral after the Designation Date until he/she makes a subsequent change of election hereunder. Change of election by written, voice response or internet direction may be delivered or transmitted
by a Non-Bargaining Unit Participants at any time, but shall be effective only as of the Designation Date next following the date of the filing of such change of election with the Committee.

an amount from one percent (1%) to fourteen percent (14%) of such Bargaining Unit Participant’s Adjusted Total Compensation paid during the Payroll Period, in one percent (1%) increments to be made by payroll deduction, provided
that such Bargaining Unit Participant is an active Participant in the Plan during a portion of such Payroll Period, and such Reduction in Compensation shall become the Company’s 401(k) Contribution for such Participant;


 For Plan Years beginning on or after January 1, 2005, for each Payroll Period each Employee who is a Bargaining Unit
Participant in this Plan may elect a Reduction in Compensation in an amount of one percent (1%) to twenty-four percent (24%) of such Bargaining Unit Participant’s Adjusted Total Compensation paid during the Payroll Period, in one
percent (1%) increments to be made by payroll deduction, provided that such Bargaining Unit Participant is an active Participant in the Plan during a portion of such Payroll Period, and such Reduction in Compensation shall be the Company’s
401(k) Contribution for such Participant. 
  

	 	2.	Provided, further that a Bargaining Unit Participant’s Reduction in Compensation shall not exceed the limitation on excludible elective deferrals for such Participant’s
taxable year, provided in Code Section 402(g), subject to applicable cost-of-living adjustment thereunder, or as provided in any successor provision of federal tax law. 

  

	 	3.	For purposes of the foregoing and the Plan “Catch-Up Contributions” are Elective Deferrals made to the Plan that are in excess of an otherwise applicable Plan limit and
that are made by Participants who are aged fifty (50) or over by the end of their taxable years. An otherwise applicable limit is a limit in the Plan that applies to Elective Deferrals without regard to Catch-Up Contributions, such as limits on
annual additions, the dollar limit on Elective Deferrals Under Code Section 402(g) (not counting Catch-Up Contributions) and the limit imposed on the actual deferral percentage (ADP) test under Code Section 401(k)(3). Catch-Up
Contributions for a Participant for a taxable year may not exceed (1) the dollar limit on Catch-Up Contributions under Code Section 414(v)(2)(B)(I) for the taxable year or (2) when added to other Elective Deferrals, 75 percent of the
Participant’s Compensation for the taxable year. 

  

 -21- 









	 	4.	Notwithstanding the foregoing, on or about the end of each calendar quarter in a Plan Year, a Bargaining Unit Participant will be allowed to contribute in a lump sum amount the
additional cash necessary to meet his/her maximum contribution percentage. Such pre-tax catch-up contributions will be made through payroll deduction and must be greater than $25.00. In a Plan Year a Bargaining Unit participant will be allowed to
make such catch-up contribution for previous quarters in the Plan Year. This catch-up contribution shall be considered in determining the Company’s Matching Contribution for such Bargaining Unit Participant to the extent provided in Article VII
of the Plan. 

  

	 	5.	The Reduction in Compensation elected by a Bargaining Unit Participant shall remain in effect until changed by such Participant’s delivery of a change of election in the manner
provided herein. A Bargaining Unit Participant may change his/her Reduction in Compensation only on a Designation Date. A Bargaining Unit Participant’s change of election may designate a different percentage of Reduction in Compensation,
subject to the terms and conditions of the Plan; and may state that such Participant elects no Reduction in Compensation and deferral after the Designation Date until he/she makes a subsequent change of election hereunder. Change of election by
written, voice response or internet direction may be delivered or transmitted by a Bargaining Unit Participants at any time, but shall be effective only as of the Designation Date next following the date of the filing of such change of election with
the Committee. 

  

	3.	Roth 401(k) Elective Deferrals

	 	1.	This paragraph of the Plan will apply to contributions beginning January 1, 2007. 

  


	 	2.	As of the effective date under paragraph 1, the Plan will accept Roth Elective Deferrals made on behalf of Participants. A Participant’s Roth Elective Deferrals shall be
allocated to a separate account maintained for such deferrals as described in paragraph 3.B of this Article III, below. 

  

	 	3.	Unless specifically stated otherwise, Roth Elective Deferrals will be treated as elective deferrals for all purposes under the Plan. 

  

	 	4.	A Participant may make Roth Elective Deferrals with catch-up contributions that are elective deferrals to the extent allowed by Code Section 402A. 

 B. Separate Accounting. 
  

	 	1.	Contributions and withdrawals of Roth Elective Deferrals will be credited and debited to the Roth Elective Deferral Account maintained for each Participant.


  

 -22- 









	 	2.	The Plan will maintain a record of the amount of Roth Elective Deferrals in each Participant’s account. 

  

	 	3.	Gains, losses, and other credits or charges must be separately allocated on a reasonable and consistent basis to each Participant’s Roth Elective Deferral Account and the
Participant’s other accounts under the Plan. 

  

	 	4.	No contributions other than Roth Elective Deferrals and properly attributable earnings will be credited to each Participant’s Roth Elective Deferral Account.


 C. Direct Rollovers. 
  

	 	1.	Notwithstanding the provisions of Article V of the Plan, a direct rollover of a distribution from a Roth Elective Deferral Account under the Plan will only be made to another Roth
Elective Deferral Account under an applicable retirement plan described in Code Section 402A(e)(1) or to a Roth IRA described in Code Section 408A, and only to the extent the rollover is permitted under the rules of Code
Section 402(c). 

  

	 	2.	Notwithstanding anything to the contrary in the provisions of Article V of the Plan, or any other provisions of the Plan, the Plan will not accept any rollover contribution to a
Roth Elective Deferral Account under the Plan from any other qualified plan, annuity contract or other type of plan, account or arrangement. 

  

	 	3.	The Plan will not provide for a direct rollover (including an automatic rollover) for distributions from a Participant’s Roth Elective Deferral Account if the amount of the
distributions that are eligible rollover distributions are reasonably expected to total less than $200 during a year. In addition, any distribution from a Participant’s Roth Elective Deferral Account is not taken into account in determining
whether distributions from a Participant’s other accounts are reasonably expected to total less than $200 during a year. However, eligible rollover distributions from a Participant’s Roth Elective Deferral Account are taken into account in
determining whether the total amount of the Participant’s account balances under the Plan exceeds $1,000 for purposes of mandatory distributions from the Plan. 

  

	 	4.	Any provisions of the Plan that allow a participant to elect a direct rollover of only a portion of an eligible rollover distribution but only if the amount rolled over is at least
a specified dollar amount are to be applied by treating any amount distributed from the Participant’s Roth Elective Deferral Account as a separate distribution from any amount distributed from the Participant’s other accounts in the Plan,
even if the amounts are distributed at the same time. 

 D. Correction of Excess Contributions. 
  

	 	1.	In the case of a distribution of excess contributions, a Highly Compensated Employee may designate the extent to which the excess amount is composed of pre-tax elective deferrals
and Roth Elective Deferrals but only to the extent such types of deferrals were made for the year.

provisions of the Plan generally applicable to a distribution of any elective deferral made by a Participant under the Plan. 

  

	 	2.	If the Highly Compensated Employee does not designate which type of elective deferrals are to be distributed, the Plan will distribute pre-tax elective deferrals first.


  

	 	3.	No Participant loan shall be allowed from a Participant Roth Elective Deferral Account. 

  

	 	 4.
	 The Committee and Plan shall provide written information to each Participant who is eligible to make a Roth Elective

Reduction in Compensation under paragraph 2. of this Article III, will not cause such Participant’s total elective deferrals of Compensation for the year to exceed the 

  

 -24- 








 
maximum permissible amount which may be deferred under Code Section 402(g) for the taxable year, and shall be subject to the reductions thereof as
determined by the Committee in order to comply with applicable limitations in Code Sections 401(k) and 415 as provided in paragraphs 2., 3., and 7. of Article VIII. The fourteen percent (14%) of Compensation limitation on a Non-Bargaining Unit

the Company or any subsidiary of the Company. The allowance of any rollover contribution shall be at the discretion of the Committee, and only in accordance with such terms and conditions as the Committee may prescribe. The Participant’s
rollover contribution shall constitute an additional deposit in, and become a part of the accounts of the Participant for all purposes of the Plan, and become subject to all the terms and provisions of this Plan, except that the Company shall have
no obligation to contribute any amount, out of its net earnings and earned surplus, or otherwise, to or for the benefit of a Participant on account of any such rollover contribution by the Participant. Any Participant’s rollover contribution
shall be received, deposited, held, and invested in such manner as the Committee shall by regulation prescribe, consistent with the investment and accounting provisions of this Plan. 
 For purposes of this paragraph 1., a “qualified pension or profit-sharing plan” shall mean a plan qualified under Section 401(a) of the Code and ERISA; and a “qualifying rollover distribution”
shall mean a distribution to a Participant from a trust which forms a part of the Company or a subsidiary qualified pension or profit-sharing Plan which distribution constitutes a distribution qualifying for rollover to this Plan pursuant to Code
Section 402(c) (or corresponding provision of any future federal tax code). 
  

	2.	Trust to Trust Transfers From Other Plans of The Company 

 The
Company may, from time to time, direct the Trustee to receive, accept transfers of, and hold as a part of the Trust, deposits or transfers of the funds, deposits, property, assets, and/or accounts of Participants, or employees of any subsidiary of
the Company, from a trust which is part of any other qualified defined benefit plan or qualified defined contribution plan of the Company or any subsidiary of the Company. Any such deposit or transfer shall be subject to prior written approval of
the Company, and may be pursuant to a modification, continuation, termination, partial termination, consolidation or merger with, or replacement of any such other Company plan or subsidiary plan which may be adopted by the Company or the subsidiary
employer, or pursuant to any other arrangement mutually determined and agreed upon by the Company and a subsidiary and/or the subsidiary employee (or Participant). If an employee of the Company or of a subsidiary of the Company whose account is so
transferred is otherwise eligible and not already participating in the Plan, he/she shall become a Participant at the time of such transfer and deposit. Any funds or property from the account of a Participant under another Company plan or a
subsidiary plan which are so transferred and accepted by the Trustee shall be received and deposited in full to an account or accounts of that Participant under this Plan, and shall thereupon become a part of the Trust held for the account of that
Participant in accordance with all the terms and provisions of the Plan. The 

  

 -28- 








 
Committee shall determine and prescribe reasonable and appropriate procedures, certifications, and other requirements to be accomplished and performed by the
Company, the Trustee, the Participant, any such subsidiary and the plan administrator and trustee of such other Company plan or subsidiary plan, in order to assure an effective and satisfactory transfer of trust funds, and any such transfer shall be
conditioned upon compliance with all such requirements. Notwithstanding any of the foregoing, the Company shall have no obligation to make any matching or other additional contributions to the Plan to or for the benefit of any Participant by reason
of any such transfer or deposit to the Trust under this paragraph 2. 
  

	3.	Direct Rollovers 

 A. General. This paragraph applies to
distributions made after December 31, 2001. Notwithstanding any provision of the Plan to the contrary that might otherwise limit a Distributee’s election under the Plan, 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. 
 B. Definitions. For purposes of this paragraph the following definitions shall apply: 
  

	 	1.	Eligible Rollover Distribution. An Eligible Rollover Distribution is any distribution of all or any portion of the balance to the credit of the Distributee, except that an
Eligible Rollover Distribution does not include: any distribution that is one of a series of substantially equal periodic payments (not less frequently than annually) made for the life (or life expectancy) of the Distributee or the joint lives (or
joint life expectancies) of the Distributee and the Distributee’s designated beneficiary, or for a specified period of ten (10) years or more; any distribution to the extent such distribution is required under Code Section 401(a)(9);
any hardship distribution; the portion of any other distribution(s) that is not includible in gross income (determined without regard to the exclusion for net unrealized appreciation with respect to employer securities). 

 A portion of a distribution shall not fail to be an Eligible Rollover Distribution merely because the portion consists of after-tax employee contributions
which are not includible in gross income. However, such portion may be transferred only to an individual retirement account or annuity described in Code Section 408(a) or (b), or to a qualified defined contribution plan described in Code
Sections 401(a) or 403(a) that agrees to separately account for amounts so transferred, including separately accounting for the portion of such distribution which is includible in gross income and the portion of such distribution which is not so
includible. 
  

	 	2.	 Eligible Retirement Plan. An Eligible Retirement Plan is an eligible plan under Code Section 457(b) 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 the Plan, an individual retirement account described in Code
Section 408(a), an individual retirement annuity described in Code Section 408(b), an annuity described 



  

 -29- 









	 	 
in Code Section 403(a), an annuity described in Code Section 403(b), or a qualified plan described in Code Section 401(a), that accepts the
Distributee’s eligible rollover distribution. The definition of Eligible Retirement Plan shall also apply in the cases of a distribution to a surviving spouse, or to a spouse or former spouse who is the alternate payee under a qualified
domestic relations order, as defined in Code Section 414(p). 


 If any portion of an Eligible Rollover Distribution is
attributable to payments or distributions from a Designated Roth Account, an Eligible Retirement Plan with respect to such portion shall include only another Designated Roth Account of the individual from whose Account the payments and distributions
were made, or a Roth IRA of such individual. 
  

	 	3.	Distributee. A Distributee includes a Participant, Employee or former Employee. In addition, the Participant’s, Employee’s or former Employee’s surviving
spouse and the Participant’s, Employee’s or former Employee’s spouse or former spouse who is the alternate payee under a qualified domestic relations order, as defined in Code Section 414(p), are Distributees with regard to the
interest of the spouse or former spouse. 

  

	 	4.	Direct Rollover. A Direct Rollover is a payment by the Plan of the Eligible Retirement Plan specified by the Distributee. 

 C. Automatic Rollovers. In the event of a mandatory distribution from the Plan greater than One Thousand Dollars ($1,000) in accordance with the provisions of the
Plan, if the Participant does not elect to have such distribution paid directly to an Eligible Retirement Plan specified by the Participant in a Direct Rollover or to receive the distribution directly in accordance with the Plan, then the Committee
will pay the distribution in a Direct Rollover to an individual retirement account designated by the Committee. For purposes of determining whether a mandatory distribution is greater than One Thousand Dollars ($1,000), the portion of the
Participant’s distribution attributable to any rollover contribution is included. 
 D. Rollovers From Other Plans. The Plan will accept
rollovers from other plans as follows: 
  

	 	1.	Direct Rollovers. The Plan will accept a direct rollover of an Eligible Rollover Distribution from: 

  

	 	(a)	Qualified plan described in Code Section 401(a) or 403(a), including after-tax employee contributions, except no direct rollover of Roth 401(k) deferrals shall be allowed or
accepted. 

  

	 	(b)	An annuity contract described in Code Section 403(b), excluding after-tax employee contributions. 

  

	 	(c)	An eligible plan under Code Section 457(b) 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. 

  

 -30- 









	 	2.	Participant Rollover Contributions from Other Plans. The Plan will accept a Participant contribution of an Eligible Rollover Distribution from: 

  

	 	(a)	A qualified plan described in Code Section 401(a) or 403(a). 

  

	 	(b)	An annuity contract described in Code Section 403(b). 

  

	 	(c)	An eligible plan under Code Section 457(b) 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. 

  

	 	3.	Participant Rollover Contributions from IRAs. The Plan will accept a Participant rollover contribution of the portion of a distribution from a traditional individual
retirement account or annuity described in Code Section 408(a) or 408(b) that is eligible to be rolled over and would otherwise be includible in gross income. 

  

	 	4.	No Rollover of Roth Elective Deferrals or Contributions. Notwithstanding the foregoing or any other provision of the Plan, the Plan will not accept any rollover contributions
to a Roth Elective Deferral Account under the Plan or any other rollover transfer or payment of Roth 401(k) deferrals or contributions from any other qualified plan, annuity contract, or other type of plan, account, or arrangement.


  

	4.	Rollover of Nontaxable Distributions 

 The portion of a distribution
of a Participant’s Account that is not includible in gross income for federal income tax purposes may be transferred in a direct trustee-to-trustee transfer to a qualified trust or to an annuity contract described in Code Section 403(b)
that provides for separate accounting for amounts so transferred (and earnings thereon), including separately accounting for the portion of such distribution which is includible in gross income and the portion of such distribution which is not so
includible, or to an eligible retirement plan, as provided in Code Section 402(c)(2)(A).” 
  

	5.	Trust to Trust Transfers From Plans of Other Employers 

 The Company
may, from time to time, direct the Trustee to receive, accept transfers of, and hold as a part of the Trust, deposits or transfers of the funds, deposits, property, assets, and/or accounts of Participants from a trust which is part of any qualified
defined contribution plan of another employer. Any such deposit or transfer shall be subject to prior written approval of the Company, and may be pursuant to a modification, continuation, termination, partial termination, consolidation or merger
with, or replacement of any such other plan which may be adopted by the Company, or pursuant to any other arrangement mutually determined and agreed upon by the Company and such other employer. If an employee of the Company whose account is so
transferred is otherwise eligible and not already participating in the Plan, he/she shall become a Participant at the time of such transfer and deposit. Any funds or property from the account of a Participant under the plan of another employer which
are so transferred and accepted by the Trustee shall be received and deposited in full to an account or accounts of that Participant under this Plan, and shall thereupon become a part of the Trust held for the account of that Participant in
accordance with all the terms and provisions of the Plan. The Committee shall 

  

 -31- 








 
determine and prescribe reasonable and appropriate procedures, certifications, and other requirements to be accomplished and performed by the Company, the
Trustee, the Participant, the plan administrator and trustee of such other employer plan, in order to assure an effective and satisfactory transfer of trust funds, and any such transfer shall be conditioned upon compliance with all such
requirements. 
 No transfer may be made to the Trust of the Plan of any Roth elective deferrals from any other plan or trust. 
 Notwithstanding any of the foregoing, the Company shall have no obligation to make any matching or other additional contributions to the Plan to or for the benefit of
any Participant by reason of any such transfer or deposit to the Trust under this Paragraph 5. 
  

	6.	Separately Accounted For Rollovers From Other Plans 

 Notwithstanding the foregoing or any other provision of the Plan, the Plan may separately account for amounts attributable to rollover contributions by Participants to the Plan. If such separate accounting is prescribed and made pursuant to
direction of the Committee, the amounts attributable to such rollover contributions shall be subject to the general rules otherwise applicable to distributions under the Plan, unless and until there is an amendment of the Plan to expressly provide
that such amounts may be distributed at any time pursuant to the Participant’s request. Provided, that any distributions of amounts attributable to a rollover contribution from another plan is subject to the survivor annuity requirements of
Code Sections 401(a)(11) and 417, and the minimum distribution requirements of Code Section 401(a)(q) and additional income tax under Section 72(t) to the extent otherwise applicable to the Plan and Participants.” 
  

	7.	Rollover to IRA for Non-Spouse Beneficiary 

 A direct
trustee-to-trustee transfer may be made of any portion of a distribution of the Plan Account of a deceased Participant or Employee to an individual retirement account established for the purpose of receiving the distribution on behalf of an
individual who is a designated beneficiary of the Participant or Employee and who is not the surviving spouse of the Participant or Employee pursuant to Code Section 402(c)(11) and Article XIII, paragraph 5 of the Plan. 
  

 -32- 








 ARTICLE VI. 
 SUSPENSION OF SALARY REDUCTIONS, DEPOSITS 
  

	1.	Suspension of Reduction in Compensation or After-Tax Deposits by Participant for Deficiency in Compensation 

 A Participant may, at any time elect in writing, in the manner prescribed by the Committee, to suspend his/her elected Reduction in Compensation or After-Tax Deposits in
any regular pay period in which either would normally be deducted pursuant to his/her prior election. In any pay period in which a Reduction in Compensation or After-Tax Participant Deposit would normally be deducted from such a Participant’s
pay, such Reduction in Compensation or After-Tax Participant Deposit will be automatically suspended without notice if his/her net pay for such pay period is insufficient to permit the deduction to be made in full. 
  

	2.	Reinstatement of Voluntarily Suspended Reduction in Compensation or After-Tax Deposits 

 A Participant may at any time elect in writing to reinstate his/her Reduction in Compensation or After-Tax Participant Deposit to the Plan which he/she previously voluntarily suspended. Such election to reinstate a
previously suspended Reduction in Compensation or After-Tax Participant Deposit shall be made in the manner prescribed by the Committee and shall be effective on the first day of the calendar quarter next following the end of the calendar month in
which the Participant’s written election for such reinstatement is received by the Company. 
  

 -33- 








 ARTICLE VII. 
 COMPANY MATCHING CONTRIBUTIONS 
  

	1.	Company Matching Contributions 

 The Company shall make Matching
Contributions for Participants in the Plan as provided for in this Article VII, below. 
 For Plan Years beginning prior to January 1, 2008, as provided
under the Plan in and for such Plan Years, after a Participant has completed one (1) Year of Service as an Employee of the Company, subject to the limitations specified herein and in Article VIII, the Company shall regularly contribute, out of
its net earnings and earned surplus as reflected by its books of account, and shall pay to the Trustee at least monthly, amounts of Matching Contributions equal to the Company’s 401(k) Contributions for a Participant or a Participant’s
After-Tax Deposits for that month, as provided herein below. 
 For Plan Years beginning on and after January 1, 2008, upon and after a Non-Bargaining
Unit Participant’s commencement of participation in the Plan, subject to the limitations specified herein and in Article VIII, the Company shall regularly contribute, out of its net earnings and earned surplus as reflected by its books of
account, and shall pay to the Trustee at least monthly, amounts of Matching Contributions equal to the Company’s 401(k) Contributions for that Non-Bargaining Unit Participant, or that Non-Bargaining Unit Participant’s After-Tax Deposits
for that month, as provided for herein below. 
 For Plan Years beginning on and after January 1, 2008, after a Bargaining Unit Participant has
completed one (1) Year of Service as an Employee of the Company, subject to the limitations specified herein and in Article VIII, the Company shall regularly contribute, out of its net earnings and earned surplus as reflected by its books of
account, and shall pay to the Trustee at least monthly, amounts of Matching Contributions equal to the Company’s 401(k) Contributions for that Bargaining Unit Participant, or that Bargaining Unit Participant’s After-Tax Deposits for that
month, as the case may be, as provided for herein below. 
 A. Non-Bargaining Unit Participants 
  

	 	1.	The Company shall make a Matching Contribution for each Non-Bargaining Unit Participant which shall be equal to the Company’s 401(k) Contribution for such Participant based
upon such Participant’s elected Reduction in Compensation and deferral for that month, subject to the limitation stated in clause (3) of this subparagraph 1.A., below; provided, that the Company shall not make any Matching Contribution for
such a Non-Bargaining Unit Participant with respect to that part of the Company’s 401(k) Contribution that is an ESOP Dividend Distribution/Additional Deferral Contribution made for such Participant. 

  

	 	2.	After making the Matching Contribution provided for in subparagraph A. of this paragraph 1., above, the Company shall make a Matching Contribution for each Non-Bargaining Unit
Participant which shall be equal to such Participant’s After-Tax Deposits for that month, subject to the limitation stated in clause (3) of this subparagraph 1.A., below. 

  

 -34- 









	 	3.	The aggregate Matching Contributions of the Company under clauses (1) and (2) of this subparagraph 1.A. for a Non-Bargaining Unit Participant hereunder shall not exceed
six percent (6%) of the Non-Bargaining Unit Participant’s Compensation. 

  

	 	4.	A full Matching Contribution shall be made for a Participant whose 401(k) Contributions equal the deferral limitation under Code Section 402(g) prior to the Plan limit on
Matching Contributions being reached for the Plan Year. If the Company’s 401(k) Contributions based upon a Participant’s elected Reduction in Compensation equal the Code Section 402(g) limitation at any time during a Plan Year, and
when such limitation is reached no further Company 401(k) Contributions or After-Tax Deposits are made for or by such Participant for that Plan Year, and the amount of Matching Contributions made for the Plan Year is then less than the Maximum
Matching Contribution Amount, the Company shall thereafter make one or more monthly Matching Contributions for the Participant in that Plan Year until the total Matching Contributions made for the Participant for that Plan Year equal such Maximum
Matching Contribution Amount. For purposes of this subparagraph A.4, the term “Maximum Matching Contribution Amount” shall mean lesser of (i) the total amount of the Company’s 401(k) Contributions for the Participant and the
Participant’s After-Tax Contributions for that Plan Year, or (ii) six percent (6%) of the total of the Participant’s monthly compensation for all months in that Plan Year. 

 B. Bargaining Unit Participants. On and after July 1, 2004, for each payroll period the Company shall make a Matching Contribution for each Bargaining Unit
Participant equal to one hundred percent (100%) of the percentage of any Company 401(k) Contribution and of any After-Tax Deposit for the Payroll Period times such Bargaining Unit Participant’s Annual Compensation; provided, , that the
Company’s Matching Contribution for a Payroll Period shall apply only to the first six percent (6%) of the amount of any Bargaining Unit Participant’s Annual Compensation paid for the Payroll Period, and any Matching Contribution
shall only be made with respect to any Bargaining Unit Participant’s Adjusted Total Compensation for Payroll Periods beginning after the first day of the calendar month coincident with or next following completion of one (1) year of
service by such Bargaining Unit Participant. The Company’s maximum Matching Contribution shall in all cases be allocated and contributed first to match the Company’s 401(k) Contribution for the Participant’s Reduction in Compensation
for that month, and shall then be allocated and contributed to match a Participant’s After-Tax Deposit only to the extent such Participant’s Reduction in Compensation for that month is less than the Company’s maximum Matching
Contribution for that month. If necessary to meet the limitations of paragraphs 2., 3., 4., or 7. of Article VIII, the Company’s Matching Contributions for a Participant shall be reduced in the manner determined by the Committee. Such
reductions shall be made in a uniform and nondiscriminatory manner, determined by the Committee in its sole discretion, which are needed to comply with such limitations. For information and reference with respect to administration of the Plan prior
to July 1, 2004, a 

  

 -35- 








 
seventy-five percent (75%) matching contribution percentage was effective on and after June 5, 2001, for Bargaining Unit Participants who were
Group A Bargaining Unit Employees; and was effective on and after July 1, 2001, for Bargaining Unit Participants who were Group B Bargaining Unit Employees; and a one hundred percent (100%) matching contribution percentage was effective on
and after July 20, 2003, for Bargaining Unit Participants who were Group B Bargaining Unit Employees. 
  

	2.	Participant’s Matching Contribution Account 

 The
Company’s Matching Contribution shall be credited to each participating Participant’s Employer Contribution Account. 
  

	3.	Re-entry of Participant 

 If a former Participant whose employment
has terminated shall be rehired as an Employee, he/she shall be entitled to have all his/her prior service counted for purposes of the one (1)-year service requirement for entitlement to Company Matching Contributions. 
  

	4.	USERRA 

 The Company matching contributions provided for under the
Plan shall be provided in accordance with the special rules relating to veterans rights under USERRA in Code Section 414(u). 
  

 -36- 








 ARTICLE VIII. 
 LIMITATIONS ON CONTRIBUTIONS AND ANNUAL ADDITIONS 
  

	1.	General 

 Company contributions, After-Tax Deposits, and other
contributions under the Plan shall be limited as provided in this Article VIII. 
  

	2.	Limitation on Elective Deferrals; Catch-Up Contributions 

 No
Participant shall be permitted to have Elective Deferrals made under this Plan, or any other plan, contract or arrangement maintained by the Company, during any calendar year, in excess of the dollar limitation contained in Code Section 402(g)
in effect for the Participant’s taxable year beginning in such calendar year. In the case of a Participant aged fifty (50) or over by the end of the taxable year, the dollar limitation described in the preceding sentence includes the
amount of Elective Deferrals that can be Catch-Up Contributions. The dollar limitation contained in Code Section 402(g) is $10,500 for taxable years beginning in 2000 and 2001, increasing to $11,000 for taxable years beginning in 2002 and
increasing by $1,000 for each year thereafter up to $15,000 for taxable years beginning in 2006 and later years. After 2006, the $15,000 limit will be adjusted by the Secretary of the Treasury for the cost-of-living increases under Code
Section 402(g)(4). Any adjustments will be in multiples of $500. 
 For purposes of the foregoing and the Plan “Catch-Up Contributions” are
Elective Deferrals made to the Plan that are in excess of an otherwise applicable Plan limit and that are made by Participants who are aged fifty (50) or over by the end of their taxable years. An otherwise applicable limit is a limit in the
Plan that applies to Elective Deferrals without regard to Catch-Up Contributions, such as limits on annual additions, the dollar limit on Elective Deferrals under Code Section 402(g) (not counting Catch-Up Contributions) and the limit imposed
on the actual deferral percentage (ADP) test under Code Section 401(k)(3). Catch-Up Contributions for a Participant for a taxable year may not exceed (1) the dollar limit on Catch-Up Contributions under Code Section 414(v)(2)(B)(i)
for the taxable year or (2) when added to other Elective Deferrals, 75 percent of the Participant’s Compensation for the taxable year. The dollar limit on Catch-Up Contributions under Code Section 414(v)(2)(B)(i) is $1,000 for taxable
years beginning in 2002, increasing by $1,000 for each year thereafter up to $5,000 for taxable years beginning in 2006 and later years. After 2006, the $5,000 limit will be adjusted by the Secretary of the Treasury for cost-of-living increases
under Code Section 414(v)(2)(C). Any such adjustments will be in multiples of $500. Catch-Up Contributions are not subject to the limits on annual additions, are not counted in the ADP test and are not counted in determining the minimum
allocation under Code Section 416 (but Catch-Up Contributions made in prior years are counted in determining whether the Plan is top-heavy). 
 Provisions in the Plan relating to Catch-Up Contributions apply to Elective Deferrals made after 2001. 
  

 -37- 









	3.	Actual Deferral Percentage Limitations 

 The Actual Deferral
Percentage for the Highly Compensated Employees for the Plan Year shall not exceed the greater of A. or B. as follows: 
 A. The Actual Deferral Percentage
for the preceding Plan Year for all those Employees eligible to be Participants in this Plan who are not Highly Compensated Employees, multiplied by 1.25, or 
 B. The Actual Deferral Percentage for the preceding Plan Year for those Employees eligible to be Participants in this Plan who are not Highly Compensated Employees multiplied by two (2); provided, however, that under this subparagraph 3.B.
limitation the Actual Deferral Percentage for the Highly Compensated Employees may not exceed the Actual Deferral Percentage for the preceding Plan Year for the Employees eligible to be Participants in this Plan who are not Highly Compensated
Employees by more than two (2) percentage points. 
 This limitation shall be applied and used in testing under the prior or preceding year method under
Code Section 401(k)(3). Provided, the Company may amend the Plan to provide that it elects to apply the limitations of subparagraphs A. and B. of this paragraph by using the Actual Deferral Percentage of eligible Participants who are not Highly
Compensated Employees for the Plan Year rather than the preceding Plan Year in accordance with applicable Regulations, except that if such election is made, it may not be changed except as provided by the Internal Revenue Service under Code
Section 401(k)(3). 
 If any Highly Compensated Employee is a participant in two (2) or more cash or deferred arrangements of the Company, for
purposes of determining the Actual Deferral Percentage with respect to such Participant, all such cash or deferred arrangements shall be treated as one (1) cash or deferred arrangement, for purposes of this paragraph and the Plan, in accordance
with Code Section 401(k)(3) and Treasury Regulations §1.401(k)-1(g). 
 If two (2) or more plans which include cash or deferred arrangements
are considered as one (1) plan for purposes of Code Section 401(a)(4) or 410(b), the cash or deferred arrangements included in such plans shall be treated as one (1) arrangement for purposes of this paragraph and the Plan, in
accordance with Code Section 401(k)(3) and Treasury Regulations §§1.401(k)-1(b)(3) and 1.401(k)-1(g). 
  

	4.	Limitations on Company Matching Contributions 

 The Matching
Contribution Percentage for eligible Highly Compensated Employees for any Plan Year shall not exceed the greater of (i) one hundred twenty-five percent (125%) of such percentage for all other eligible Employees, for the preceding Plan
Year, or (ii) the lesser of two hundred percent (200%) of such Matching Contribution Percentage for all other eligible Employees for the preceding Plan Year, or such Matching Contribution Percentage for all other eligible Employees for the
preceding Plan Year, plus two (2) percentage points. 
 This limitation shall be applied and used in testing under the prior or preceding year method
under Code Section 401(m)(2). Provided, the Company may amend the Plan to provide that elects to apply the limitations of this paragraph by using the Plan Year rather than the preceding Plan Year, in accordance with applicable Regulations,
except that if such election is made, it may not be changed except as provided by the Internal Revenue Service under Code Section 401(m)(2). 
  

 -38- 








 If two (2) or more plans of the Company to which matching contributions, employee contributions, or elective
deferrals are made are treated as one (1) plan for purposes of Code Section 410(b), such plans shall be treated as one (1) plan for purposes of this paragraph and the Plan, for purposes of this paragraph and the Plan, in accordance
with Code Section 401(m)(2)(B) and Treasury Regulations §1.401(m)-1(f). 
 If a Highly Compensated Employee participates in two (2) or more
plans of the Company to which contributions to which Code Section 401(m) applies are made, all such contributions shall be aggregated for purposes of this paragraph and the Plan, in accordance with Code Section 401(m)(2)(B) and Treasury
Regulations §§1.401(m)-1(b)(3) and 1.401(m)-1(f). 
  

	5.	Separate Application of Limitations 

 If this Plan is maintained by
separate employers as a multiple employer plan, the Actual Deferral Percentage limitations in paragraph 3. above, and the Matching Contribution Percentage limitations in paragraph 4. above, shall be applied as if each separate employer maintaining
this Plan as a multiple employer plan maintained a separate plan. 
  

	6.	Multiple Use of Alternative Limitation 

 If any Highly Compensated
Employee is eligible to elect to make Reductions in Contributions and to make After-Tax Deposits or to receive Company Matching Contributions under the Plan, and the sum of the Actual Deferral Percentage of the entire group of eligible Highly
Compensated Employees and the actual contribution percentage of the entire group of eligible Highly Compensated Employees under the Plan subject to Code Section 401(m) exceeds the aggregate limit specified in Treasury Regulations
Section 1.401(m)-2(b)(2), or succeeding regulations prescribed under Code Section 401(m)(9), then such excess shall be corrected by reduction of the Actual Deferral Percentage or the actual contribution percentage of Highly Compensated
Employees in accordance with the provisions of Treasury Regulations Section 1.401(m)-2(c) or succeeding regulations. 
 Notwithstanding the foregoing,
or other applicable provisions of the Plan containing the same requirements, restrictions on multiple use do not apply for Plan Years beginning after 2001. 
  

	7.	Limitation on Allocations; Annual Additions 

 Pursuant to this
paragraph 7, contributions and other additions to the Plan with respect to any Participant for any taxable year shall not exceed the limitation provided in Code Section 415(c)(3), expressed as an Annual Adition to the Participant’s
account, which limitation is the greater of (i) $40,000 (adjusted for increases in the cost-of-living pursuant to Code Section 415(d)), or (ii) 100% of the Participant’s Compensation, as described and provided herein below.

  

 -39- 








 A. Limitation for Participant that Participates in No Other Plan. 
  

					
	1.	  	    (a)	  	If the Participant does not participate in, and has never participated in another qualified plan maintained by the Company or a welfare benefit fund, as defined in §419(e) of the Code
maintained by the Company, or an individual medical account, as defined in §415(l)(2) of the Code, maintained by the Company, or a simplified employee pension, as defined in §408(k) of the Code, maintained by the Company, which provides an
Annual Addition as defined in paragraph 7.C.1., below, the amount of Annual Additions which may be credited to the Participant’s account for any Limitation Year will not exceed the lesser of the Maximum Permissible Amount or any other
limitation contained in the Plan.

  

	 	(b)	If the Company contribution that would otherwise be contributed or allocated to the Participant’s Account would cause the Annual Additions for the Limitation Year to exceed the
Maximum Permissible Amount, the amount contributed or allocated will be reduced so that the Annual Additions for the Limitation Year will equal the Maximum Permissible Amount. 

  

	 	2.	Prior to determining the Participant’s actual Compensation for the Limitation Year, the Company may determine the Maximum Permissible Amount for a Participant on the basis of a
reasonable estimation of the Participant’s Compensation for the Limitation Year, uniformly determined for all Participants similarly situated. 

  

	 	3.	As soon as is administratively feasible after the end of the Limitation Year, the Maximum Permissible Amount for the Limitation Year will be determined on the basis of the
Participant’s actual Compensation for the Limitation Year. 

  

	 	4.	If pursuant to paragraph 7.A.3., above, or as a result of the allocation of forfeitures, there is an Excess Amount the excess will be disposed of as follows:


  

	 	(a)	Any nondeductible voluntary employee contributions(plus attributable earnings), to the extent they would reduce the Excess Amount, will be returned to the Participant;


  

	 	(b)	If after the application of subparagraph 4.(a) an Excess Amount still exists, any elective deferrals (plus attributable earnings), to the extent they would reduce the Excess Amount,
will be distributed to the Participant; 

  

	 	(c)	If after the application of subparagraph 4.(b) an Excess Amount still exists, and the Participant is covered by the Plan at the end of the Limitation Year, the Excess Amount in the
Participant’s Account will be used to reduce Company contributions (including any allocation of forfeitures) for such Participant in the next Limitation Year, and each succeeding Limitation Year if necessary. 

  

 -40- 









	 	(d)	If after the application of paragraph (b) an Excess Amount still exists, and the Participant is not covered by the Plan at the end of a Limitation Year, the Excess Amount will
be held unallocated in a suspense account. The suspense account will be applied to reduce future Company contributions for all remaining Participants in the next Limitation Year, and each succeeding Limitation Year if necessary.


  

	 	(e)	If a suspense account is in existence at any time during a Limitation Year pursuant to this paragraph, it will not participate in the allocation of investment gains and losses. If a
suspense account is in existence at any time during a particular Limitation Year, all amounts in the suspense account must be allocated and reallocated to Participants’ accounts before any Company or any employee contributions may be made to
the Plan for that Limitation Year. Excess Amounts may not be distributed to Participants or former Participants. 

 B. Limitation for
Participant that Participates in Other Plan. 
  

					
	1.	  	    (a)	  	This paragraph 7.B. applies if, in addition to this Plan, the Participant is covered under another qualified defined contribution plan maintained by the Company, a welfare benefit fund
maintained by the Company, an individual medical account maintained by the Company, or a simplified employee pension maintained by the Company, that provides an Annual Addition as defined in paragraph 7.C.1., during any Limitation
Year.

  

	 	(b)	The Annual Additions which may be credited to a Participant’s Account under this Plan for any such Limitation Year will not exceed the Maximum Permissible Amount reduced by the
Annual Additions credited to a Participant’s account under the other qualified defined contribution plans, welfare benefit funds, individual medical accounts, and simplified employee pensions for the same Limitation Year.


  

	 	(c)	If the Annual Additions with respect to the Participant under other qualified defined contribution plans, welfare benefit funds, individual medical accounts, and simplified employee
pensions maintained by the Company are less than the Maximum Permissible Amount and the Company contribution that would otherwise be contributed or allocated to the Participant’s Account under this Plan would cause the Annual Additions for the
Limitation Year to exceed this limitation, the amount contributed or allocated will be reduced so that the Annual Additions under all such plans and funds for the Limitation Year will equal the Maximum Permissible Amount. 


 

	 	(d)	If the Annual Additions with respect to the Participant under such other qualified defined contribution plans, welfare benefit funds, individual medical accounts, and simplified
employee pensions in the aggregate are equal to or greater than the Maximum Permissible Amount, no amount will be contributed or allocated to the Participant’s Account under the Plan for the Limitation Year. 

  

 -41- 









	 	2.	Prior to determining the Participant’s actual Compensation for the Limitation Year, the Company may determine the Maximum Permissible Amount for a Participant in the manner
described in paragraph 7.A.2., above. 

  

	 	3.	As soon as is administratively feasible after the end of the Limitation Year, the Maximum Permissible Amount for the Limitation Year will be determined on the basis of the
Participant’s actual Compensation for the Limitation Year. 

  

	 	4.	If, pursuant to paragraph 7.B.3., above, or as a result of the allocation of forfeitures, a Participant’s Annual Additions under the Plan and such other plans would result in
an Excess Amount for a Limitation Year, the Excess Amount will be deemed to consist of the Annual Additions last allocated, except that Annual Additions attributable to a simplified employee pension will be deemed to have been allocated first,
followed by Annual Additions to a welfare benefit fund or individual medical account, regardless of the actual allocation date. 

  

	 	5.	If an Excess Amount was allocated to a Participant on an allocation date of the Plan which coincides with an allocation date of another plan, the Excess Amount attributed to the
Plan will be the product of, 

  

	 	(a)	the total Excess Amount allocated as of such date, times 

  

	 	(b)	the ratio of (i) the Annual Additions allocated to the Participant for the Limitation Year as of such date under the Plan to (ii) the total Annual Additions allocated to
the Participant for the Limitation Year as of such date under this and all the other qualified defined contribution plans. 

  

	 	6.	Any Excess Amount attributed to this Plan will be disposed in the manner described in paragraph 7.A.4. 

 C. Definitions. The following definitions shall apply for purposes of this paragraph 7, and is applicable under the Plan. 
  

	 	1.	Annual Additions: The sum of the following amounts credited to a Participant’s Account for the limitation year: 

  

	 	(a)	Company contributions; 

  

	 	(b)	Employee contributions; 

  

	 	(c)	Forfeitures; 

  

 -42- 









	 	(d)	Amounts allocated to an individual medical account, as defined in Code Section 415(l)(2), which is part of a pension or annuity plan maintained by the Company are treated as
Annual Additions to a defined contribution plan. Also amounts derived from contributions paid or accrued which are attributable to post-retirement medical benefits, allocated to the separate account of a key employee, as defined in Code
Section 419A(d)(3), under a welfare benefit fund, as defined in Code Section 419(e), maintained by the Company are treated as Annual Additions to a defined contribution plan; and 

  

	 	(e)	Allocations under a simplified employee pension. 

 For this
purpose, any Excess Amount applied under paragraphs 7.A.4. and 7.B. in the Limitation Year to reduce Company contributions will be considered Annual Additions for such Limitation Year. 
  

	 	2.	Compensation: Compensation is defined as wages, salaries, and fees for professional services and other amounts received (without regard to whether or not an amount is paid in
cash) for personal services actually rendered in the course of employment with the Company or employer maintaining the Plan to the extent that the amounts are includable in gross income (including, but not limited to, commissions paid salesmen,
compensation for services on the basis of a percentage of profits, commissions on insurance premiums, tips, bonuses, fringe benefits, and reimbursements or other expense allowances under a nonaccountable Plan (as described in Treasury Regulations
§1.62-2(c) ), and excluding the following: 

  

	 	(a)	Employer contributions to a plan of deferred compensation which are not includible in the Employee’s gross income for the taxable year in which contributed, or Employer
contributions under a simplified employee pension plan, or any distributions from a plan of deferred compensation; 

  

	 	(b)	Amounts realized from the exercise of a non-qualified stock option, or when restricted stock (or property) held by the Employee either becomes freely transferable or is no longer
subject to a substantial risk of forfeiture; 

  

	 	(c)	Amounts realized from the sale, exchange or other disposition of stock acquired under a qualified stock option; and 

  

	 	(d)	Other amounts which received special tax benefits, or contributions made by the Employer (whether or not under a salary reduction agreement) towards the purchase of an annuity
contract described in Code Section 403(b) (whether or not the contributions are actually excludable from the gross income of the Employee). 

 In general, for purposes of applying the limitations of this paragraph 7., Compensation for a Limitation Year is the Compensation actually paid or made available in gross income during such Limitation Year.

  

 -43- 








 Notwithstanding the preceding sentence, Compensation for a Participant in a defined contribution plan who
is permanently and totally disabled (as defined in Code Section 22(e)(3)) is the Compensation such Participant would have received for the Limitation Year if the Participant had been paid at the rate of Compensation paid immediately before
becoming permanently and totally disabled. 
  

	 	3.	Defined Contribution Dollar Limitation: $40,000, as adjusted under Code Section 415(d). 

  

	 	4.	Company: For purposes of this paragraph, Company shall mean the Company and subsidiaries that adopt the Plan, and all members of a controlled group of corporations (as
defined in Code Section 414(b), as modified by Code Section 415(h)), all commonly controlled trades or businesses (as defined in Code Section 414(c), as modified by Code Section 415(h)) or affiliated service groups (as defined in
Code Section 414(m)) of which the adopting entity is a part, and any other entity required to be aggregated with the Company pursuant to regulations under Code Section 414(o). 

  

	 	5.	Excess Amount: The excess of the Participant’s Annual Additions for the Limitation Year over the maximum permissible amount. 

  

	 	6.	Limitation Year: A calendar year. All qualified plans maintained by the Company must use the same Limitation Year. If the Limitation Year is amended to a different
12-consecutive month period, the new Limitation Year must begin on a date within the Limitation Year in which the amendment is made. 

  

	 	7.	Maximum Permissible Amount: 

 For limitation years
beginning on or after January 1, 2002, except for catch up contributions described in Code Section 414(v), 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 lesser of: 
  

	 	(a)	The Defined Contribution Dollar Limitation. 

  

	 	(b)	100 percent of the Participant’s Compensation for the Limitation Year. 

 The compensation limit referred to in (b) shall not apply to any contribution for medical benefits after separation from service (within the meaning of Code Section 401(h) or Code Section 419A(f)(2)),
which is otherwise treated as an Annual Addition. 
 If a short limitation year is created because of an amendment changing the Limitation
Year to a different 12-consecutive month period, the maximum permissible amount will not exceed the defined contribution dollar limitation multiplied by the following fraction: 
  

					
		  	Number of months in the short limitation year	  	
		  	12	  	

  

 -44- 









	8.	No Return or Diversion of Contributions Except for Mistake 

 Except
as provided in paragraphs 9. and 10. of this Article VIII below, the Trustee shall hold the Company’s contributions in the respective Participants’ Accounts, subject to the provisions of the Plan; and no part of those contributions shall
be recoverable by the Company, nor shall they be used for, or diverted to any other purpose, except for return thereof to the Company in the case and to the extent of its contributions having been made by reason of a mistake of fact, in which case
the return to the Company of the amount involved shall be made within one (1) year of the mistaken contribution; and if a contribution to the Plan conditioned upon the deductibility of the contribution under Code Section 404, as provided
in paragraph 14. of this Article VIII, then such contribution may be returned to the Company (to the extent disallowed) within one (1) year after the disallowance of the deduction; provided, that any contribution for a Participant which exceeds
the limitations provided in paragraphs 2. and 3. of this Article VIII shall be distributed to the Participant as directed by the Committee within a reasonable period of time consistent with requirements for distributing excess deferrals under the
Code and regulations thereunder. 
  

	9.	Distribution of Excess Deferrals 

 If any Excess Deferrals are
included in the gross income of a Participant for any taxable year under Code Section 402(g)(1), (or corresponding section of any future federal tax code), then not later than March 1 following the close of the taxable year, such
Participant may allocate the amount of such Excess Deferrals among the plans under which the Excess Deferrals were made and may notify the Committee of the portion allocated to the Plan; and not later than April 1 following the close of the
taxable year, the Plan may distribute to such Participant the amount allocated to the Plan (and any income allocable to such amount). Such distribution of the Excess Deferrals of a Participant may be made notwithstanding any other provision of the
Plan, the Code, or ERISA; provided, that except to the extent provided in applicable Treasury Regulations, notwithstanding the distribution of such portion of Excess Deferrals from the Plan, such portion shall be treated as a contribution of the
Company for purposes of applying the limitations in paragraphs 3. and 4. of this Article VIII and Code Section 401(k). If the Plan distributes only a portion of any Excess Deferrals allocated to the Plan and income allocable thereto, such
portion shall be treated as having been distributed ratably from the Excess Deferral allocable to the Plan and the income. 
  

	10.	Excess 401(k) Contributions 

 In the event there are Excess
Contributions under the limitations of Code Section 401(k) for any Plan Year actually paid over to the Trust on behalf of Highly Compensated Employees, then the Committee may, in its sole discretion, direct the Trustee to distribute the amount
of such Excess Contributions for such Plan Year (and any income allocable to such Excess Contributions). Notwithstanding any other provision of this Plan, Excess Contributions plus any income and minus any loss allocable thereto, shall be
distributed no later than the last day of each Plan Year to Participants to whose accounts such Excess Contributions were allocated for the preceding 

  

 -45- 








 
Plan Year; provided, that such distribution shall be made as promptly as practicable, so as to avoid the effect of Code provisions stating that if such
excess amounts are distributed more than 2 1/2 months after the last day of the Plan Year in which such excess amounts arose, a
ten percent (10%) excise tax will be imposed on the employer maintaining the Plan with respect to such amounts. Excess Contributions shall be allocated to the Highly Compensated Employees with the largest amounts of Company contributions taken
into account in calculating the Actual Deferral Percentage test for the year in which the excess arose, beginning with the Highly Compensated Employee with the largest amount of such Company contributions and continuing in descending order until all
the Excess Contributions have been allocated. For purposes of the preceding sentence the “largest amount” is determined after distribution of Excess Contributions. If such excess amounts are distributed more than two and one-half (2 1/2) months after the last day of the Plan Year in which such excess amounts arose, a 10-percent excise tax will be imposed on
the Company with respect to such amounts. 
 Excess Contributions (including the amounts recharacterized) shall be treated as annual additions
under the Plan. 
 Excess Contributions shall be adjusted for any income or loss up to the end of the Plan Year. Unless otherwise determined by the
Committee, the income or loss allocable to Excess Contributions is the income or loss allocable to the Participant’s Elective Deferral account (and, if applicable, the Qualified Non-elective Contribution account or the Qualified Matching
Contributions account or both) for the Plan Year multiplied by a fraction, the numerator of which is such Participant’s Excess Contributions for the year and the denominator is the Participant’s account balance attributable to Elective
Deferrals (and Qualified Non-Elective Contributions or Qualified Matching Contributions, or both, if any of such contributions are included in the Actual Deferral Percentage test) without regard to any income or loss occurring during such Plan Year.

 Excess Contributions shall be distributed from the Participant’s Elective Deferral account and Qualified Matching Contribution account (if
applicable) in proportion to the Participant’s Elective Deferrals and Qualified Matching Contributions (to the extent used in the Actual Deferral Percentage test) for the Plan Year. Excess Contributions shall be distributed from the
Participant’s Qualified Non-elective Contribution account only to the extent that such Excess Contributions exceed the balance in the Participant’s Elective Deferral account and Qualified Matching Contribution account. 
 The Committee may, in its sole discretion, permit a Participant to treat his or her Excess Contributions as an
amount distributed to the Participant and then contributed by the Participant to the Plan. Such recharacterized amounts will remain nonforfeitable and subject to the same distribution requirements as Elective Deferrals under the Plan. Amounts may
not be recharacterized by a Highly Compensated Employee to the extent that such amount in combination with other Participant contributions made by the Participant would exceed any stated limit under the Plan on Participant contributions. Any such
recharacterization must occur no later than two and one-half (2 1/2) months after the last day of the Plan Year in which
such Excess Contributions arose and is deemed to occur no earlier than the date the last Highly Compensated Employee is informed in writing of the amount recharacterized and the consequences thereof. Recharacterized amounts will be taxable to the
Participant for the Participant’s tax year in which the Participant would have received them in cash. 
  

 -46- 








 If and to the extent Excess Contributions (and income allocable thereto) are distributed, such Excess Contributions and
allocable income shall be designated by the Company as a distribution of Excess Contributions (and income) and shall be distributed to the appropriate Highly Compensated Employees after the close of the Plan Year in which the Excess Contributions
arose and within twelve (12) months after the close of that Plan Year. In all cases, for purposes of the foregoing, the income allocable to Excess Contributions shall equal the sum of the allocable gain or loss for the Plan Year. In addition to
the provisions stated above, the Committee may determine and use any reasonable method for computing the income allocable to Excess Contributions, which method shall be nondiscriminatory in favor of Highly Compensated Employees, be used consistently
for all Participants and for all corrective distributions under the Plan for the Plan Year, and be used by the Plan for allocating income to Participants’ accounts. 
 The amount of Excess Contributions to be distributed or to be recharacterized under the foregoing provisions of this Article VIII with respect to a Participant shall be reduced by any Excess Contributions previously
distributed to the Participant for the Participant’s taxable year ending with or within the Plan Year in accordance with Code Section 402(g)(2), (or corresponding section of any future federal tax code), and the amount of Excess
Contributions that may be distributed with respect to a Participant for a taxable year shall be reduced by any Excess Contributions previously distributed or recharacterized with respect to the Participant for the Plan Year beginning with or within
the taxable year, in the manner necessary to satisfy the applicable provisions of the Treasury Regulations under Code Section 401(k). 
  

	11.	Excess Aggregate Contributions 

 In the event the aggregate amount of Matching Contributions and employee contributions (and any qualified nonelective contribution or elective contribution taken into account in computing the contribution percentage)
actually made on behalf of Highly Compensated Employees for any Plan Year is an amount in excess of the maximum amount of such contributions permitted under the limitations on matching contributions stated in paragraph 4. of this Article VIII
(determined by reducing contributions made on behalf of Highly Compensated Employees in order of their contribution percentages beginning with the highest of such percentages), then the Committee may, in its sole discretion, direct the Trustee to
distribute the amount of such excess of such contributions for such Plan Year (and any income allocable to such contributions), but the distribution of such excess contributions (and income) shall be made within two and one-half (2 1/2) months after the close of such Plan Year. Any distribution of such excess aggregate contributions for any Plan Year shall be
made to Highly Compensated Employees on the basis of the amount of contributions on behalf of, or by, each such Highly Compensated Employee. 
 The
determination of the amount of such excess aggregate contributions with respect to the Plan shall be made after (i) first determining the excess deferrals (within the meaning of Code Section 402(g) (or corresponding section of any future
federal tax code)), and (ii) then determining the excess 401(k) Contributions under paragraph 3. of this Article VIII. 
  

 -47- 








 Notwithstanding any other provision of this Plan, Excess Aggregate
Contributions, plus any income and minus any loss allocable thereto, shall be distributed no later than the last day of each Plan Year to Participants to whose accounts such Excess Aggregate Contributions were allocated for the preceding Plan Year;
provided, that such distribution shall be made as promptly as practicable, so as to avoid the effect of Code provisions stating that if such Excess Aggregate Contributions are distributed more than 2 1/2 months after the last day of the Plan Year in which such excess amounts arose, a ten percent (10%) excise tax will be imposed on the employer maintaining the Plan
with respect to those amounts. 
 Excess Aggregate Contributions shall be treated as annual additions under the Plan. 
 Excess Aggregate Contributions shall be adjusted for any income or loss up to the end of the Plan Year. Unless otherwise determined by the Committee, the income or loss
allocable to Excess Aggregate Contributions is the income or loss allocable to the Participant’s Employee Contribution account Matching Contribution account, Qualified Matching Contribution account (if any, and if all amounts therein are not
used in the Actual Deferral Percentage test) and, if applicable, Qualified Non-elective Contribution account and Elective Deferral account for the Plan Year multiplied by a fraction, the numerator of which is such Participant’s Excess Aggregate
Contributions for the year and the denominator is the Participant’s account balance(s) attributable to Contribution Percentage Amounts without regard to any income or loss occurring during such Plan Year. 
 Excess Aggregate Contributions shall be distributed on a pro-rata basis from the Participant’s Employee Contribution account, Matching Contribution account, and
Qualified Matching Contribution account (and, if applicable, the Participant’s Qualified Non-elective Contribution account or Elective Deferral account, or both). 
 The method of distributing Excess Aggregate Contributions shall in all cases satisfy the requirements of Code Section 401(a)(4), and after any correction by means of such distributions, each level of matching
contributions must be currently and effectively available to a group of Employees that satisfies Code Section 410(b), and in correcting Excess Aggregate Contributions by means of distributions, Participant contributions may not be distributed
to Highly Compensated Employees to the extent needed to meet the requirements of Code Section 401(m)(2) while Matching Contributions attributable to Participant Contributions remain allocated to Highly Compensated Employees’ accounts;
provided, that a method of distributing Excess Aggregate Contributions may include the distribution of unmatched Participant contributions that exceed the highest rate at which Participant contributions are matched before matched Participant
contributions, or the distribution of Matching Contributions prior to Participant contributions. 
 The distribution of Excess Aggregate Contributions under
this paragraph shall include all income applicable thereto. The income allocable to Excess Aggregate Contributions is equal to the sum of the allocable gain or loss for the Plan Year. In addition, to the provisions stated above, the Committee may
determine and use any reasonable method for computing the income allocable to Excess Aggregate Contributions, which method shall be nondiscriminatory in favor of Highly Compensated Employees, be used consistently for all Participants and for all
corrective distributions under the Plan for the Plan Year, and be used by the Plan for allocating income to Participants’ accounts. 
  

 -48- 









	12.	Qualified Nonelective and Matching Contributions 

 The Company may,
in its sole discretion, elect to make Qualified Nonelective Contributions and Qualified Matching Contributions that are to be treated as 401(k) Contributions in order to satisfy the Actual Deferral Percentage tests prescribed in paragraph 3. of this
Article VIII, and treated as Company Matching Contributions, to satisfy the nondiscrimination tests prescribed in paragraph 4. of this Article VIII provided that such Qualified Nonelective Contributions or Qualified Matching Contributions shall be
treated as 401(k) Contributions or Company Matching Contributions, provided that they satisfy the requirements for such treatment prescribed by the applicable Treasury Regulations. The term “Qualified Nonelective Contributions” means
Company contributions to the Plan other than 401(k) Contributions and Company Matching Contributions that satisfy the requirements of the nondiscrimination requirements of the Plan provided in paragraph 3. of this Article VIII, and the distribution
limitations applicable to 401(k) Contributions under the Plan, Code Section 401(k)(2)(B), and Treasury Regulations Section 1.401(k)-1(d). 
 The
amount of any nonelective contributions to the Plan, including those Qualified Nonelective Contributions treated as elective contributions for purposes of the Actual Deferral Percentage test, must satisfy the requirements of Code
Section 401(a)(4) and Treasury Regulations thereunder; the amount of nonelective contributions, excluding those Qualified Nonelective Contributions treated as elective contributions for purposes of the Actual Deferral Percentage Test and those
nonelective contributions treated as matching contributions for purposes of the Actual Deferral Percentage Test must satisfy the requirements of Code Section 401(a)(4) and applicable Treasury Regulations thereunder; and the Qualified
Nonelective Contributions and Qualified Matching Contributions must satisfy the requirements of Treasury Regulation § 1.401(k)-1(b)(4)(i)(A) for the Plan Year as if such contributions were elective contributions. 
 The aggregation requirements specified in Treasury Regulations § 1.401(k)-1(b)(5)(vi) shall be satisfied with respect to any taking into account of Qualified
Nonelective Contributions and Qualified Matching Contributions for purposes of the Actual Deferral Percentage test. 
 The Plan shall be administered by the
Committee to assure that the amount of nonelective contributions, including those Qualified Nonelective Contributions treated as Matching Contributions for purposes of the Actual Contribution Percentage test, shall satisfy the requirements of Code
Section 401(a)(4) and the Treasury Regulations thereunder. The amount of nonelective contributions, excluding those Qualified Nonelective Contributions treated as Matching Contributions for purposes of the Actual Contribution Percentage test
and those Qualified Nonelective Contributions treated as elective contributions under Code Section 401(k) for purposes of the Actual Deferral Percentage Test, shall satisfy Code Section 401(a)(4) and the Treasury Regulations thereunder;
the elective contributions, including those treated as Matching Contributions for purposes of the Actual Contribution Percentage Test must satisfy the requirements of Code Section 401(k)(3); the Qualified Nonelective Contributions shall be
allocated to the Participant under the Plan as of a date within the Plan Year, and the elective contributions shall satisfy Code Section 401(k) and the Treasury Regulations thereunder for the Plan Year; and the aggregation of plans requirements
of Treasury Regulations § 1.401(m)-1(b)(5)(v) shall be satisfied. 
  

 -49- 









	13.	Plan Not Dependent Upon Earnings; Company Contributions Limited to Earnings 

 This Plan is intended to be a profit-sharing plan within the meaning of Code Sections 401(a)(1) and 401(a) (27) without regard to current or accumulated earnings and profits of the Company; provided, that if at any time the
Company’s net earnings and earned surplus as reflected by its books of account are insufficient to permit the making in full therefrom of any contribution otherwise required to be made by the Company hereunder, such contributions shall be
required to be made only to the extent, if any, that such net earnings, earned surplus, and accumulated earnings and profits are sufficient, and the deficiency shall not thereafter be made up even though such earnings and profits again become
sufficient therefor; provided further, however, that the portion of this Plan which constitutes an employee stock ownership plan is intended to be a stock bonus plan within the meaning of Code Sections 401(a) and 4975(e)(7), and the Treasury
regulations thereunder which is established and maintained by the Company to provide benefits similar to those of a profit-sharing plan except that the contributions by the Company are not necessarily dependent upon profits and the benefits are
distributable in stock of the Company. 
  

	14.	Maximum Contribution 

 In no event, however, shall Company
contributions be made in excess of the amount deductible under Code Section 404, or other applicable federal law now or hereafter in effect. 
  

	15.	Application of Dollar Leveling Method. 

 The distribution of Excess
Contributions for any Plan Year shall be made to Highly Compensated Employees on the basis of the amount of contributions by, or on behalf of each Highly Compensated Employee in accordance with Code Section 401(k)(8)(C). A parallel method shall
also be used for recharacterizing Excess Contributions under Code Section 401(k)(8)(A)(ii), and for distributing Excess Aggregate Contributions under Code Section 401(m)(6)(C). 
 In order to distribute Excess Contributions (and to apply a parallel method to recharacterize Excess Contributions, or distribute Excess Aggregate Contributions, as applicable) the following procedure and method shall
be used: 
 (1) Calculate the dollar amount of Excess Contributions for each affected Highly Compensated Employee in a manner described in Code
Section 401(k)(8)(B) and Treasury Regulations § 1.401(k)-1(f)(2). However, in applying these rules, rather than distributing the amount necessary to reduce the Actual Deferral Percentage of each affected Highly Compensated Employee in
order of such Highly Compensated Employees Actual Deferral Percentages, beginning with the highest Actual Deferral Percentage, the Plan shall use these amounts in step (2.) 
 (2) Determine the total of the dollar amounts calculated in step (1). 
  

 -50- 








 This total amount in step (2) (total excess contributions) should be distributed in accordance with steps
(3) and (4), below: 
 (3) The elective contributions of the Highly Compensated Employee with the highest dollar amount of elective contributions are
reduced by the amount required to cause that Highly Compensated Employee’s elective contributions to equal the dollar amount of the elective contributions of the Highly Compensated Employee with the next highest dollar amount of elective
contributions. This amount is then distributed to the Highly Compensated Employee with the 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 reduction amount is distributed. 
 (4) If the total amount distributed is less than the total excess contributions, step
(3) is repeated. 
 After Excess Contributions and Excess Aggregate Contributions, if any, have been distributed using the method described above, the
multiple use test of Code Section 401(m)(9) shall be applied. For purposes of Code Section 401(m)(9), if a corrective distribution of excess contributions has been made, or a recharacterization has occurred, the Actual Deferral Percentage
for Highly Compensated Employees shall be deemed to be the largest amount permitted under Code Section 401(k)(3). Similarly, if a corrective distribution of excess aggregate contributions has been made, the Actual Contribution Percentage for
Highly Compensated Employees shall be deemed to be the largest amount permitted under Code Section 401(m)(2).

 ARTICLE IX. 
 INVESTMENT PROVISIONS 
  

	1.	Participant Directed Investment 

 A. Direction of Investment;
Investment Options. A Participant may, by delivery of his/her direction to the Committee in the manner and form it prescribes, in turn direct the Trustee, that any or all cash in his/her account, including his/her deposits, the Company’s
contributions, and any other cash, shall be invested under any one or more of certain designated investment options made available under the Plan. The Committee shall in turn furnish or cause the Participant’s investment direction to be
delivered to and acted upon by the Trustee within such period of time as the Committee determines to be reasonable and practicable in the circumstances. A Participant’s initial direction of investment shall be in written form as prescribed by
the Committee. A Participant may, after initial written direction of investment, give directions for changes in the investment of his/her account by written direction, use of the telephone voice response system established by the Committee and
Trustee for the Plan, or through the internet in the manner prescribed by the Committee. Investment in certain options may be limited to retention and maintenance of prior contributions invested in such options, with no further investment of
contributions therein being permitted, as more particularly provided below. The Company may establish, modify and change the investment options made available to Participants from time to time, with such modifications and changes to be made by
written action of the Chief Executive Officer of the Company and the Committee, or as otherwise determined by the Company. A Participant may also change his investment direction and direct sales from time to time to the extent permitted and
authorized in subparagraphs 1.B. and D., and paragraph 3. below. 
 B. Qualified Default Investment of Participant Account 
  

	 	1.	Notwithstanding the foregoing, if a Participant fails or refuses to direct the investment of all or any part of his/her Participant Account the amount of the Account that is not
directed to be invested by the Participant shall be invested in a Qualified Default Investment Alternative that is determined by the Company and the Committee in accordance with paragraph C of this Article IX, below, and otherwise in accordance with
the Plan. 

  

	 	2.	With respect to the investment of assets in a Participant Account pursuant to this paragraph, the following requirements and conditions shall apply: 

  

	 	(a)	The assets shall be invested in Qualified Default Investment Alternative as defined herein. 

  

	 	(b)	The Participant or beneficiary on whose behalf the investment is made shall have had an opportunity to direct investment of assets of his/her Participant Account but did not direct
the investment of the assets. 

  

 -52- 









	 	(c)	The Participant or beneficiary on whose behalf an investment is made in such a Qualified Default Investment Alternative shall be furnished with a notice that satisfies the
requirements set forth below. 

  

	 	(d)	Any material provided to the Plan relating to a Participant’s or beneficiary’s investment in a Qualified Default Investment Alternative shall be provided to the
Participant or beneficiary. 

  

	 	(e)	Any Participant of beneficiary on whose behalf assets are invested in a Qualified Default Investment Alternative may, consistent with the terms of the Plan (but not less frequently
than once within any three (3) month period) transfer, in whole or in part, such assets to any other investment option or alternative available under the Plan without financial penalty. 

  

	 	(f)	The Plan shall otherwise offer a broad range of investment alternatives within the meaning of 29 CFR 2550.404c-1(b)(3). 

  

	 	3.	For investment of a Participant Account pursuant to this paragraph the Participant shall be provided written notice of Qualified Default Investment Alternative investment of his/her
Participant Account in a manner determined to be understood by the average Plan Participant and that contains a description of the circumstances under which assets of the individual account of a Participant and beneficiary may be invested on behalf
of the Participant or beneficiary in a Qualified Default Investment Alternative; a description of the Qualified Default Investment Alternative under the Plan, including a description of the investment objectives, risk and return characteristics, and
fees and expenses attendant to the investment alternative; a description of the right of Participants and beneficiaries on whose behalf assets are invested in a Qualified Default Investment Alternative to direct the investment of those assets to any
other investment option under the Plan, without financial penalty; and an explanation of where the Participants and beneficiaries can obtain investment information concerning the other investment options under the Plan.”


  

	 	4.	For purposes of the foregoing and the Plan, the term “Qualified Default Investment Alternative” shall mean an investment option established and maintained under the Plan
that meets the requirements and conditions for treatment as a qualified default investment alternative under 29 CFR §2550.404c-5. 

 C.
Investment Options. The investment options existing and recognized under the Plan and Trust, shall be established as hereinabove provided, and regularly listed and described to Participants by written information and memoranda, and by
electronic media, furnished by and at the direction of the Committee from time to time. The investment options shall include ONEOK, Inc. Common Stock and other investments determined by the Company and the Committee hereunder. It is intended that
the investment options shall provide Participants investment alternatives which will provide a Participant with a reasonable opportunity to materially affect the potential return on amounts in his/her Plan account and the degree of risk to which
such amounts are subject, and to choose from 

  

 -53- 








 
at least three (3) investment options, each of which is diversified, has materially different risk and return characteristics, and which in the
aggregate enable the Participant to achieve investment direction of risk and return characteristics within the range normally appropriate for such Participant, and when combined with investments in other alternatives will tend to allow reasonable
diversification so as to minimize risk of losses, taking into account all circumstances. 
 A Participant may, by written, telephone voice response or
internet direction to the Committee, and in turn to the Trustee, as provided above, direct that his/her deposits and account, the Company’s contributions and any other cash be deposited in such investment options. 
 A Participant who was a Participant in the Prior ONEOK, Inc. Thrift Plan or the KGS 401(k) Thrift Plan may retain in his/her account stock or securities which were
his/her prior directed investments in such Plans to the extent, and as the Committee may prescribe by written memoranda and instructions pertaining to the Plan. The Committee may prescribe the manner in which dividends or other amounts received from
such retained investments may be invested, and may limit or prescribe additional investment or reinvestment in such stock or securities. 
 Notwithstanding
any other provisions herein, the right of Participants to direct the purchase, sale or transfer of ONEOK, Inc. Common Stock for their Plan Accounts may be limited, suspended and restricted from time to time, and for such periods of time as the
Committee, in its discretion, determines to be necessary and appropriate for administration of the Plan and Trust, including, without limitation, for the purpose of determining the amount and timing of ESOP Dividend Distributions and ESOP Dividend
Distribution/Additional Deferral Contributions under the Plan. The Committee may direct such limitations, suspensions and restrictions to be made, and cause Participants and the Trustee to be given notice thereof, in the manner it determines
reasonable and practical in the circumstances. 
 The investments selected and directed by Participants may increase or decrease in value due to changes and
fluctuations in market conditions and other circumstances, and the Company, Committee and Trustee do not warrant or guarantee, by or under the Plan or otherwise, the value of any security or other investment directed by a Participant hereunder.

 Notwithstanding the foregoing, the investment by a Participant who is a Section 16 Person shall be subject to the limitations and restrictions and
other provisions of paragraph 8. of this Article IX, below, with respect to any Discretionary Transactions involving the investment of his/her deposits, the Company’s contributions and any other cash attributable to his/her account. 

D. Change in Participant’s Investment Direction. Any direction by a Participant that available funds in his/her account shall be invested under a
particular investment option shall be deemed a continuing direction until changed by the Participant. A Participant may, by written direction to the Committee which shall in turn direct the Trustee in form prescribed by the Committee, by telephone
voice response system or internet direction in the manner prescribed by the Committee, or by such other means as may be authorized by the Committee, cancel or change any such investment direction from time to time; provided, that a Participant who
is a Section 16 Person shall be subject to the limitations, restrictions and other provisions of paragraph 8. of this Article IX, below, with respect to such Participant’s direction of investments that are Discretionary Transactions.

  

 -54- 








 E. Sale of Investments at Participant Direction. A Participant may (i) by written direction in form
prescribed by the Committee and countersigned by the authorized representative thereof, which countersignature shall be for the sole purpose of identification and authentication of good standing of the Participant, or (ii) by telephone voice
response system or internet, as authorized by the Committee, direct the Committee and the Trustee to sell or turn in for redemption, as may be appropriate, any security purchased at his/her direction; he/she may similarly direct the investment of
the proceeds of any such sale or redemption, with or without the addition of other available cash then in his/her account, under any one or more of the investments options currently in effect under the Plan for which additional investment of
contributions and cash may be directed; provided, that a Participant who is a Section 16 Person shall be subject to the limitations, restrictions and other provisions of paragraph 8. of this Article IX, below, with respect to the direction of
the sale or redemption transactions involving any security issued by the Company that are Discretionary Transactions, as defined by paragraph 8 of this Article IX below. 
 F. ESOP Diversification of Investments. It is intended that the Participant investment options and investment direction provisions stated above in this Article IX shall be administered in the manner which will
satisfy the investment diversification requirements of Code Section 401(a)(28) (or corresponding section of any future federal tax code) as to the portion of the Plan which constitutes an Employee Stock Ownership Plan, and in accordance with
such requirements, and notwithstanding anything otherwise provided in the Plan with respect to that portion of the Plan which constitutes an Employee Stock Ownership Plan, each Qualified Participant may elect within ninety (90) days after the
close of each Plan Year in the Qualified Election Period to direct the Plan and the Trustee as to the investment of at least twenty-five percent (25%) of such Participant’s Account in the Plan which is invested in Company securities (to
the extent such portion exceeds the amount to which a prior election under this paragraph applies). In the case of the election year in which the Participant can make his/her last election, the preceding sentence shall be applied by substituting
“fifty percent (50%)” for “twenty-five percent (25%).” The Plan shall offer at least three (3) investment options (not inconsistent with Treasury regulations published under Code Section 401(a)(28) (or corresponding
section of any future federal tax code) to each Qualified Participant making such an election and within ninety (90) days after the period during which the election may be made, the Plan shall invest the portion of the Participant’s
Account covered by the election in accordance with the election. For purposes of this paragraph, the term “Qualified Participant” means any Employee who is a Participant in the Plan who on and after January 10, 1997, completes at
least ten (10) years of participation under the Employee Stock Ownership Plan portion of the Plan and who has attained age fifty-five (55); and the term “Qualified Election Period” shall mean the 6-Plan-Year period beginning with the
later of (i) the first Plan Year in which an individual first became a Qualified Participant, or (ii) the first Plan Year beginning after December 31, 1986. The applicable portions of a Participant’s Account to which such
elections shall apply shall be determined based upon the price of Company securities on the New York Stock Exchange applied on a uniform and consistent basis, and with respect to any Company securities which are not readily tradable on an
established securities market with respect to activities carried on by the Plan all such valuations shall be by an independent appraiser, which means any appraiser meeting requirements similar to the requirements of the Treasury regulations
prescribed under Code Section 170(a)(1). 
  

 -55- 









	2.	Time of Action by Trustee on Investments 

 The Trustee will comply
with the directions of a Participant with respect to investment, sale and reinvestment as soon as practicable after receipt of such direction if they are given and received in accordance with one of the foregoing authorized means of communicating
such directions; provided, however, that in the case of directions to purchase securities, the Trustee will not comply therewith until a means to make such purchase has been adequately provided in respect to the Participant’s account. With
respect to purchases of Common Stock from the Company, the Trustee shall purchase such securities on the day or days of each month on which the Trustee receives the contributions from the Participants and the Company or receives dividends on the
Common Stock held by the Trustee. The Committee may establish such rules, regulations and procedures as it determines, in its discretion, to be necessary and appropriate for administering Participant directions of investment under the Plan. The
Trustee, in its discretion, may limit the daily volume of its purchases or sales of a security to the extent that such action is deemed by it to be in the best interest of the Participants directing such purchases or sales. 
  

	3.	Participant Rights as to Options, Rights, and Warrants 

 In the
event that any option, rights, or warrants shall be granted or issued with respect to a security held by the Trustee under the Plan, the Trustee, to the extent possible, shall give to the Participant in whose account such security is held a
reasonable opportunity (which in any event shall not extend beyond five days prior to the date of expiration of the options, rights, or warrants) to direct the Trustee to exercise such options, rights, or warrants, and if any cash shall be required
in connection with such exercise, such Participant shall, simultaneously with his/her direction to the Trustee, make available to the Trustee the necessary funds. Such funds may be made available to the Trustee by payment thereof in cash or by
written direction to the Trustee in form prescribed by the Committee to use cash held by the Trustee in the Participant’s Account or obtained from the sale of any security in such account; provided, however, that the total of any such cash
Payment and the amount of current monthly contribution shall not exceed the contribution and deposit limitations set forth in Articles III and IV. Cash payments made by a Participant to the Trustee in connection with the exercise of any such
options, rights, or warrants shall constitute an additional deposit in the Participant’s Account for all purposes of the Plan except the Company’s contributions under paragraph 1. of Article VII and except that, for a period of twelve
(12) months after making any such payment, the Participant shall have the right, by written request to the Trustee in form prescribed by the Committee, to receive payment from the Trustee out of any cash available in the Participant’s
Account an amount equal to the cash so paid, and such payment to the Participant shall not constitute a withdrawal within the meaning of Article XII or any other Article of the Plan. Any securities acquired as the result of the exercise of any such
options, rights, or warrants shall be added to the Participant’s Account. If a Participant shall not, within the time designated by the Trustee, direct the Trustee to exercise any such option, right, or warrant and make available to the Trustee
any necessary funds, the Trustee shall sell such option, right, or warrant in the open market, if there be any market thereof. The cash proceeds from the sale of any options, rights, or warrants shall be credited to the Participant’s Account.

  

 -56- 








 Provided, that a Participant who is a Section 16 Person shall be subject to the limitations, restrictions and other
provisions of paragraph 8. of this Article IX, below, with respect to any options, rights or warrants granted or issued with respect to any security held by the Trustee of the Plan that is a security issued by the Company, if the exercise or other
action by the Participant pursuant to this paragraph 3. is a Discretionary Transaction, as defined in such paragraph 8. 
  

	4.	Redemption of Nontransferable Securities 

 In the case of the
redemption of any nontransferable security or on the maturity thereof, the Participant in whose account such security is held shall take such steps as the Trustee may prescribe in order to effect the redemption or collection thereof by the Trustee.

  

	5.	Manner of Holding Cash and Securities 

 All cash and securities in
Participants’ Accounts shall, until disposed of pursuant to the provisions of the Plan, be held in the possession of the Trustee. Transferable securities may be registered in the name of the Trustee or in the name of its nominee.
Nontransferable securities shall be issued in such name or names as the Trustee may elect, subject to any applicable laws or regulations at the time in effect with respect thereto. In the sole discretion of the Trustee, investments in a particular
security to be held in the accounts of more than one (1) Participant may be represented by a single stock certificate or a single bond, as the case may be. 
  

	6.	Voting of Shares 

 Shares of the voting stock of the Company held by
the Trustee in the account of a Participant under the Plan will be voted or consents for action with respect thereto will be granted by the Trustee or other registered owner thereof only in accordance with written instructions given to the Trustee
by the Participant, except that the Trustee, in its discretion, may vote or direct the registered owner to vote or may consent or direct the registered owner to consent to action being taken with respect to any such stock if the Trustee has not
received written instructions from the Participant in whose account such shares are held at least five (5) days prior to the date of the meeting at which such vote is to be taken or the last date that a consent of action may be given. Notice of
any such meeting or consent request shall be given by the Committee to the Participant and a request for written instructions shall be made by the Committee to be directed to the Trustee at such time and in such form as may be provided by rules and
regulations adopted by the Committee. 
 This paragraph and all pertinent provisions of the Plan and Trust shall be applied and interpreted in all respects
so as to meet the requirements of Code Section 409(e) (or corresponding section of any future federal tax code) so that each Participant or beneficiary in the Plan is entitled to direct the Plan and Trustee as to the manner in which stock and
securities of the Company which are entitled to vote and are allocated to the Participant Account of such Participant or beneficiary are to be voted. 
 This
paragraph shall also apply to the voting of any voting stock of Western Resources, Inc., in the account of any Participant. 
  

 -57- 









	7.	Tender Offers 

 Notwithstanding any other provisions of this Plan,
the provisions of this paragraph 7. shall govern the tendering of shares of Common Stock of the Company held in this Plan. 
 A. Upon commencement of a
tender offer for any securities that are Common Stock of the Company, the Company shall notify each Participant of such tender offer and utilize its best efforts to timely distribute or cause to be distributed to the Participant such information as
is distributed to shareholders of the Company in connection with such tender offer, and shall provide a means by which the Participant can instruct the Trustee whether or not to tender the shares of Common Stock of the Company allocated to such
Participant’s account. The Company shall provide the Trustee with a copy of any materials provided to Participants. 
 B. Each Participant shall have
the right to instruct the Trustee as to the manner in which the Trustee is to respond to the tender offer for any and all of the shares of Common Stock of the Company allocated to such Participant’s account. The Trustee shall respond to the
tender offer with respect to shares of Common Stock of the Company as instructed by the Participant. The Trustee shall not tender any stock allocated to a Participant’s account for which the Trustee has received no instructions from the
Participant. 
 C. The Trustee shall tender that number of unallocated shares of Common Stock of the Company which is determined by multiplying the total
number of unallocated shares by a fraction of which the numerator is the number of shares of Common Stock of the Company allocated to Participants’ accounts for which the Trustee has received instructions from Participants to tender (and such
instructions have not been withdrawn as of the date of determination) and the denominator is the total number of shares of Common Stock of the Company allocated to Participants’ accounts. 
 D. A Participant who has directed the Trustee to tender shares of Common Stock of the Company allocated to such Participant’s account may, at any time prior to the
tender offer withdrawal date, instruct the Trustee to withdraw, and the Trustee shall withdraw such shares of Common Stock from the tender offer prior to the withdrawal deadline. 
 Prior to such withdrawal deadline, if unallocated shares of Common Stock of the Company have already been tendered, the Trustee shall redetermine the number of shares of Common Stock of the Company which would be
tendered under paragraph 7.C. hereunder as if the date of such withdrawal were the date of determination, and withdraw the number of unallocated shares necessary to reduce the number of unallocated shares tendered to the amount so redetermined. A
Participant shall not be limited as to the number of instructions to tender or withdraw which he/she may give to the Trustee. 
 E. The Trustee shall credit
the proceeds received in exchange for tendered shares of Common Stock of the Company to the account from which the tendered stock originated. Notwithstanding paragraph 3. of this Article IX, each Participant to whose account amounts have been
allocated pursuant to this subparagraph E. shall have the right to direct the Trustee to immediately invest such amounts in any of the Options then available for investment under the Plan. 
  

 -58- 








 F. Notwithstanding the foregoing, a Participant who is a Section 16 Person shall be subject to the limitations,
restrictions and other provisions of paragraph 8. of this Article IX, below, with respect to any tender of shares of Common Stock allocated to such Participant’s account that is a Discretionary Transaction, as defined in such paragraph 8.

  

	8.	Section 16 Person Limitations; Discretionary Transactions 

 A
Section 16 Person shall be allowed to direct or have a Discretionary Transaction as defined below, effected under the Plan only if such Discretionary Transaction is effected pursuant to an election made at least six (6) months following
the date of the most recent election, with respect to any employee benefit plan of the Company, that effected a Discretionary Transaction that was: 
  

	 	(1)	an acquisition, if the current proposed Discretionary Transaction would be a disposition; or 

  

	 	(2)	a disposition, if the current proposed Discretionary Transaction would be an acquisition. 

 For purposes of this Article IX, the term “Discretionary Transaction” shall mean a transaction involving equity securities of the Company pursuant to an employee benefit plan of the Company that: 

 

	 	(i)	is at the volition of the Participant; 

  

	 	(ii)	is not made in connection with the Participant’s death, disability, retirement or termination of employment; 

  

	 	(iii)	is not required to be made available to the Participant pursuant to a provision of the Internal Revenue Code; and 

  

	 	(iv)	results in either an intra-plan transfer involving a Company equity securities fund under the Plan, or a cash distribution funded by a volitional disposition of a Company equity
security. 

 Except to the extent otherwise expressly stated herein, all terms and provisions contained in this paragraph 8. are intended to
have the same meaning and effect as when used in Rule 16b-3 of the Securities and Exchange Commission promulgated under the Securities Exchange Act of 1934, as amended (“SEC Rule 16b-3”). Transactions under the Plan by or with respect to
Section 16 Persons are intended to qualify for exemptions allowable under SEC Rule 16b-3, unless the Committee specifically determines otherwise; and the provisions of the Plan shall be administered, interpreted and construed to carry out such
intention, and any provision that cannot be so administered, interpreted and construed shall, to the extent permissible under the Code and the Employee Retirement Income Security Act of 1974, as amended, be disregarded. 
  

	9.	Employee Stock Ownership Plan (ESOP) 

 The portion of this Plan and
the Trust under which investment in ONEOK, Inc. Common Stock is directed by Participants pursuant to paragraph 1. of this Article IX, above, is intended to be an Employee Stock Ownership Plan designed to invest primarily in 

  

 -59- 








 
Qualifying Employer Securities, including all shares of ONEOK, Inc. Common Stock held by the Plan at the time such portion of the Plan and Trust is first
made an Employee Stock Ownership Plan by amendment of the Plan. The investment in such stock shall be made and administered in accordance with the provisions of Code Section 4975(e)(7), or succeeding provisions of the federal tax law, the
Treasury regulations thereunder, and the provisions of the Plan more specifically providing for such Employee Stock Ownership Plan, including without limitation, the provisions of this paragraph 9., stated below; paragraph 3. of Article III,
providing for deemed deferrals equal to ESOP Dividends paid and distributed; paragraph 1.E. of this Article IX providing for diversification of investments; paragraph 6. of this Article IX providing for the voting of ONEOK, Inc. Common Stock;
paragraph 2. of Article X providing for payment and distribution of ESOP Dividends on ONEOK, Inc. Common Stock; paragraph 5. of Article XI providing for the time of distribution of ONEOK, Inc. Common Stock from the Plan; and paragraph 12. of Article
XI providing for Participant rights to distribution of ONEOK, Inc. Common Stock. 
 It is intended that the Employee Stock Ownership Plan provided for herein
shall not acquire any Plan assets or Company securities by use of an exempt loan under Code Section 4975(d)(3), or otherwise, but notwithstanding the foregoing, if and to the extent any such exempt loan is ever made to or received by the Plan,
then any such loan shall conform in all respects to the requirements of Code Section 4975(e) and the Treasury regulations thereunder, and must be primarily for the benefit of Participants and their beneficiaries, and shall comply with the
following terms and conditions: (1) The interest rate respecting such loan shall not exceed a reasonable rate of interest; and the Trustee shall consider all relevant factors in determining a reasonable rate of interest, including the amount
and duration of the loan, the security and guarantee (if any) involved, the credit standing of the ESOP and the Company (if and to the extent that the Company acts as guarantor), and the interest rate prevailing for comparable loans; and upon due
consideration of the foregoing factors, a variable interest rate may be reasonable; (2) At the time that such loan is made or entered into, the interest rate and the price of securities to be acquired should not be such that Plan assets might
be dissipated; (3) The terms of such loan, whether or not between independent parties, must be at such time at least as favorable to the Trust as the terms of a comparable loan resulting from arm’s-length negotiations between independent
parties; (4) The proceeds of such loan must be used within a reasonable time after their receipt by the Trust only to acquire ONEOK, Inc. Common Stock, to repay such loan, or to repay a prior loan to the Trust; (5) Such loan must be
without recourse against the Trust; the only assets of the Trust that may be given as collateral on such loan are shares of ONEOK, Inc. Common Stock acquired therewith; no person entitled to payment under such loan shall have any right to assets of
the Trust other than collateral given for such loan, cash contributions of the Company made to meet the obligations of the Trust under such loan, and earnings attributable to such collateral and the investment of such contributions; the payments
made with respect to such loan by the Trust during a Plan Year must not exceed an amount equal to the sum of such contributions and earnings received during or prior to the year less such payments in prior years; such contributions and earnings must
be accounted for separately on the books of account of the Trust, until the loan is repaid; (6) In the event of default on such loan, the value of Plan assets transferred in satisfaction of the loan must not exceed the amount of default;
(7) Shares of ONEOK, Inc. Common Stock used as collateral for such loan shall be released from the encumbrance thereof, in accordance with the provisions stated in this paragraph 9., below; and (8) Except as otherwise provided hereinbelow
under the terms of this Plan and Trust, or as otherwise required by 

  

 -60- 








 
applicable law, no ONEOK, Inc. Common Stock or other Company security acquired with the proceeds of such loan shall be subject to a put, call or other
option, or buy-sell or similar arrangement while held by and when distributed from the Trust, whether or not the Trust is then an employee stock ownership plan as described in Code Section 4975(e)(7). 
 All shares of ONEOK, Inc. Common Stock acquired by the Trust and pledged as collateral on any such loan shall be added to and maintained in a suspense account. Said
shares shall be released from such encumbrance as follows: (1) For each Plan Year during the duration of the loan, the number of shares of ONEOK, Inc. Common Stock released shall equal the number of encumbered shares held immediately before
release by a fraction. The numerator of the fraction is the amount of principal and interest paid to the lender by the Trust for the year, and the denominator of the fraction is the sum of the numerator plus the principal and interest to be paid for
all future years; (2) For purposes of the foregoing determination, the number of future years under the loan must be definitely ascertainable, and shall be determined without taking into account any possible extensions or renewal periods. If
the interest rate under the loan is variable, the interest to be paid in future years shall be computed by using the interest rate applicable as of the end of the Plan Year; and (3) To the extent of the foregoing release from encumbrance,
shares shall be withdrawn from the suspense account, and nonmonetary units representing the Participants’ interest therein shall be allocated, for each Plan Year. The shares of ONEOK, Inc. Common Stock held in the above-described suspense
account shall be voted by the Trustee. With respect to shares released from encumbrance, said shares shall be voted as provided in paragraph 6. of this Article IX of the Plan. 
 To the extent any Company security is acquired by the Plan with the proceeds of an exempt loan, which security is not publicly traded when distributed or is subject to a trading limitation when distributed, then such
security shall be subject to a put option exercisable only by Participant (“Participant” meaning for purposes of these provisions, the Participant and beneficiaries of the Participant), such Participant’s donees, or by a person
(including an estate or its distributee) to whom such security passes by reason of such Participant’s death. Such put option must permit the Participant to put such security to the Company, and under no circumstances may the put option bind the
Plan, except that such put option may grant the Plan an option to assume the rights and obligations of the Company at the time that the put option is exercised; the put option must be exercisable at least during a fifteen (15)-month period which
begins on the date the security subject to the put option is distributed by the Plan, except that if the security is publicly traded without restriction when distributed but ceases to be so traded within fifteen (15) months after the
distribution, the Company shall notify each security holder in writing within ten (10) days after the security ceases to be so traded that for the remainder of the fifteen (15)-month period the security is subject to a put option. Such
notification shall inform the individual distributees of the terms of the put options that they are to hold. Any such put option is to be exercised by the holder notifying the Company in writing that the put option is being exercised. The period
during which such a put option is exercisable shall not include any time when the distributee is unable to exercise it because the party bound by the put option is prohibited from honoring it by applicable federal and state law. The price at which
any such put option must be exercisable is the value of the security, determined under Section 54.4795-11(d)(5) of the Treasury regulations. The terms and provisions for payment under any such put option must be reasonable terms within the
meaning of Section 54.4975-7(b)(12)(iv) of the Treasury regulations. The payment under any such put option shall not be restricted by the provisions of a loan or any other arrangement, including the Company’s certificate of incorporation,
unless so required by applicable state law. 
  

 -61- 









	10.	Investment Diversification 

 The investment options offered to
Participants under the Plan shall be established, maintained and administered in accordance with the provisions of Code Section 401(a)(35) that are applicable to the Plan. 
  

	11.	No Guarantee or Indemnity 

 Nothing contained in this Plan shall be
construed as a guarantee by the Company or by the Trustee of the value of any security in which funds held by the Trustee under the Plan are invested or as an indemnity against any loss resulting from such investments. 
  

 -62- 








 ARTICLE X. 
 CREDITS AND CHARGES TO A PARTICIPANT’S ACCOUNT 
  

	1.	General Charges and Credits 

 All interest, dividends, and other
income received by the Trustee in respect to assets included in a Participant’s Account, and all gains or losses upon the sale of securities in the Participant’s Account, as determined by the Trustee, shall be credited or charged, as the
case may be, to the Participant’s Account. 
  

	2.	ESOP Dividend Distributions 

 A. Participant ESOP Reinvestment
Election. For Plan Years beginning after December 31, 2001, any ESOP Dividend on ONEOK, Inc. Common Stock which in accordance with the Plan provisions (1) is payable in cash to the Participants in the Plan or their beneficiaries, or
(2) is payable to the Plan and is to be distributed in cash to Participants in the Plan or their beneficiaries not later than ninety (90) days after the close of the Plan Year in which paid, may at the election of such Participants or
their beneficiaries, be (A) paid as provided in clause (1) or (2) of this subparagraph A, above, or (B) paid to the Plan and reinvested in ONEOK, Inc. Common Stock. In this regard, a Participant may elect in writing to either
(i) receive and take payment in cash of one hundred percent (100%) of the ESOP Dividends for such Participant’s Account, (ii) receive and take payment in cash of fifty percent (50%) of the ESOP Dividends for his/her
Participant Account, and have the other fifty percent (50%) of such ESOP Dividends paid to the Plan and reinvested in ONEOK, Inc. Common Stock, or (iii) elect to receive and take no payment in cash of the ESOP Dividends for his/her
Participant Account and have one hundred percent (100%) of such ESOP Dividends paid to the Plan and reinvested in ONEOK, Inc. Common Stock. A Participant who for any reason fails to make and election with respect to the payment or reinvestment
of ESOP Dividends hereunder shall have all of the ESOP Dividends for his/her Participant Account paid to the Plan reinvested in ONEOK, Inc. Common Stock. Reinvestment of ESOP Dividends paid to the Plan shall be made in accordance with all applicable
provisions of the Plan providing for the investment of Plan assets in Participant Accounts and for ONEOK, Inc. Common Stock to be a permissible investment thereof under the Plan. 
 The Committee shall provide for each Participant to make an election in writing to have dividends on ONEOK, Inc. Common Stock payable to the Participant or to the Plan to be reinvested in such Common Stock, at the
time and in the manner provided in rules, forms and procedures prescribed by the Committee, which may include a required minimum amount of dividends to make an election, as determined to be administratively reasonable and practicable by the
Committee, in its discretion. 
  

 -63- 








 B. Dividend Reinvestment. 
  

	 	1.	For Plan Years prior to 2002, the Committee may cause ESOP Dividends on ONEOK, Inc. Common Stock in a Participant’s Account to be paid in cash to the Participant (or his/her
beneficiaries), and cause the Trustee to distribute in cash to a Participant (or his/her beneficiaries) ESOP Dividends paid in cash to the Trust on ONEOK, Inc. Common Stock in such Participant’s Account. Such payment and distribution in cash to
a Participant (or his/her beneficiaries) shall be in the amount determined pursuant to subparagraphs 2., 3., and 4., below. The payment and distribution of ESOP Dividends on ONEOK, Inc. Common Stock in the Account of a retired Employee or former
Employee may be made as provided in subparagraph 5., below. The distribution of such ESOP Dividends from the Trust shall be made in cash to the Participant (or his/her beneficiaries) not later than ninety (90) days after the close of the Plan
Year in which such dividends are paid to the Trust of the Plan. 

  

	 	2.	Unless a Participant who is an Employee elects otherwise pursuant to subparagraph 3., below, the amount of the ESOP Dividend Distribution, which shall be paid and distributed in
cash to a Participant who is an Employee pursuant to this paragraph 2. shall be the amount of ESOP Dividends paid on ONEOK, Inc. Common Stock in such Participant’s Account that is equal to such Participant’s ESOP Dividend/401(k) Deferrable
Amount for the year. 

  

	 	3.	In lieu of receiving payment and distribution of ESOP Dividends in cash pursuant to subparagraph 2., above, a Participant who is an Employee may elect to receive payment and
distribution in cash of either (i) one hundred percent (100%) of the Participant’s ESOP Dividends, or (ii) fifty percent (50%) of the Participant’s ESOP Dividends. If a Participant elects to receive one hundred percent
(100%) of his/her ESOP Dividends in cash, no ESOP Dividend Distribution/Additional Deferral Contribution shall be made with respect to such payment and distribution under paragraph 4. of Article III, above; and if a Participant elects to
receive payment and distribution of fifty percent (50%) of his/her ESOP Dividends in cash, no ESOP Dividend Distribution/Additional Deferral Contribution shall be made with respect to such amount under paragraph 4. of Article III, above.


  

	 	4.	If a Participant who is an Employee elects to receive payment and distribution of fifty percent (50%) of his/her ESOP Dividends under subparagraph 3., above, then an additional
payment and distribution in cash of and from the other fifty percent (50%) of such Participant’s ESOP Dividends shall be made to such Participant in an amount equivalent to the amount, if any, of such Participant’s ESOP
Dividend/401(k) Deferrable Amount, and an ESOP Dividend Distribution/Additional Deferral Contribution equal to such additional payment and distribution of ESOP Dividends shall be made to the extent provided for in paragraph 4. of Article III, above.


  

	 	5.	Each individual who is a retired Employee, or a former Employee who has separated from service with the Company, may elect in writing to receive and take a payment and distribution
in cash of either (i) one hundred percent (100%) of his/her ESOP Dividends, or (ii) fifty percent (50%) of his/her ESOP Dividends, notwithstanding that such individual shall have no right to elect any deferral of Compensation
with respect to the dividend distribution to be received. 

  

 -64- 









	 	6.	The elections provided to a Participant who is an Employee under the foregoing provisions of subparagraph 3., above, are intended to allow such Participant to elect to receive
payment and distribution of ESOP Dividends from the Company and/or the Trust so as to increase the dollar amount of cash he/she receives in the form of ESOP Dividends by the percentage elected, without any corresponding offset of such amount by any
ESOP Dividend Distribution/401(k) Deferral Contribution or Reduction in Compensation under the Plan. 

  

	 	7.	It is also intended that unless a Participant elects otherwise, a corresponding ESOP Dividend Distribution/Additional Deferral Contribution will be made with respect to ESOP
Dividends paid and distributed in cash to a Participant under subparagraphs 2. or 4., above, to the extent provided therein and in paragraph 4. of Article III. 

  

	 	8.	Notwithstanding the foregoing, the payment and distribution in cash of ESOP Dividends with respect to ONEOK, Inc. Common Stock in a Participant Account may be limited in a uniform
and consistent manner, as determined by the Committee, so as to maximize the application of the limitations on elective deferrals and contributions contained in Code Sections 402(g) and 415 to a Participant’s regularly designated elective
deferrals of Compensation, and Company Matching Contributions thereon during a Plan Year, before application of such limitations with respect to any ESOP Dividend Distribution/Additional Deferral Contributions made by and for Participant arising
during the Plan Year. 

  

	 	9.	The payment and distribution of ESOP Dividends in cash pursuant to this paragraph 2.B. and the making of ESOP Dividend Distribution/Additional Deferral Contributions shall be
administered by the Company and the Trustee, as determined, prescribed and found mutually acceptable by the Committee and the Trustee. Any amount of ESOP Dividends not so paid and distributed in cash to a Participant, retired Employee or former
Employee under the foregoing provisions shall be credited to and remain in the Participant Account and shall not thereafter be distributable under the provisions of this paragraph, unless otherwise directed and approved by the Committee.


  

	 	10.	The elections made by Participants, retired Employees and former Employees to receive distributions of ESOP Dividends hereunder shall be made in writing at the time and in the form
prescribed by the Committee. 

  

	3.	Calculation of Charges and Credits to Participant Accounts 

 Except
as otherwise directed by the Committee, within its discretion, the cost to be charged to a Participant’s Account of any security purchased by the Trustee according to the Participant’s direction shall be the cost of such security at the
closing market price on the date such purchase is directed; and the proceeds credited to a Participant’s Account upon the sale or redemption of any securities shall be the actual proceeds thereof. 
  

 -65- 









	4.	Commissions, Taxes, and Charges on Security Purchases and Sales 

 Brokerage commissions, transfer taxes, and other charges and expenses in connection with the purchase or sale of securities shall be added to the cost of such securities or deducted from the proceeds thereof, as the case may be. 

 

	5.	Investment Management Fees 

 Investment management fees charged or
incurred by any person, firm, or entity for the management of investments made in or by any fund in connection with a Participant’s investment in particular investment options shall be charged against the Participant’s Account as the
Committee may prescribe and direct from time to time. 
  

	6.	Allocation of Plan Administrative Expenses 

 The Committee may
direct and cause all or part of reasonable Plan administrative expenses to be allocated and charged to the Plan accounts of current and former employees and their beneficiaries on a pro rata or other reasonable basis; and such allocation may from
time to time be made by allocating all or part of certain reasonable Plan expenses to the Plan accounts of former employees on pro rata or other reasonable basis without similarly allocating and charging such expenses to the Plan accounts of current
employees. Any allocation of such expenses to the Plan accounts of current and former employees pursuant to this paragraph may be made on a pro rata or other reasonable basis as determined and set forth in written rules or procedures adopted by the
Committee which shall be consistently applied in a manner that complies with the requirements of Code Section 411(a)(11), Title I of ERISA, and applicable guidelines on such allocation published by the Internal Revenue Service and Department of
Labor, including, without limitation, Revenue Ruling 2004-10 and Department of Labor Field Assistance Bulletin (FAB) 2003-3. 
  

	7.	Calculation of Credits for Redemption 

 Upon the redemption or
maturity or any nontransferable Government bonds included in a Participant’s Account, the difference between the cost thereof and the amount received upon such redemption or maturity shall be credited to the Participant’s Account as
income. 
  

	8.	Taxes 

 Taxes, if any, on any assets held by the Trustee or income
therefrom which are payable by the Trustee shall be charged against the Participants’ Accounts as the Trustee shall determine.

 ARTICLE XI. 
 VESTING AND LIQUIDATION OF ACCOUNTS 
  

	1.	Vesting of Participant and Company Contributions 

 A
Participant’s contributions under Article IV and his/her rights in the accrued benefit derived therefrom are nonforfeitable. The Company’s 401(k) Contributions and Matching Contributions for the account of a Participant, and any income and
earnings therefrom and accretions thereon, shall become vested in such Participant immediately upon payment of such contributions to the Trustee and receipt by the Trustee of such income, earnings and accretions, and (subject to subsequent loss
through decline in value of investments) the Participant may not thereafter be deprived of such funds under any provision of the Plan. All accounts of a Participant under the Plan shall be nonforfeitable. The vesting of benefits under the Plan for a
Participant shall be provided in accordance with the provisions of USERRA contained in Code Section 414(u), or corresponding provision of any future tax code. 
  

	2.	Withdrawals 

 The Company’s contributions and Participant
After-Tax Deposits credited to the account of a Participant, and the income and earnings on and accretions to a Participant’s account whether derived from the Participant’s deposits or the Company’s contributions or from any other
funds at any time in said account, may be withdrawn by or paid to the Participant upon request by the Participant as provided for in Article XII or upon complete liquidation of the Participant’s account as provided for in paragraphs 3., 7., and
8. of this Article XI, or upon termination of the Plan as provided in paragraph 10. of Article XII or upon adverse modification of the Plan as provided in paragraph 3. of Article XXIV or upon termination of the Trust as provided in paragraph 5. of
Article XXIV. 
  

	3.	Distribution of Participant Accounts 

 Except as provided in
paragraph 6. of this Article XI, when a Participant dies or his/her employment with the Company is terminated by retirement or for any other reason (except transfer of employment to a subsidiary of the Company participating in the Plan), the account
of such Participant under the Plan will be completely liquidated, and the entire balance of the account will be distributed in a single payment to the Participant, or his/her surviving spouse, beneficiaries or legatees, or heirs, respectively,
whichever is entitled thereto. The determination of the distributee or distributees in the event of a Participant’s death shall be made in accordance with Article XIII of the Plan. Every distribution on death of a Participant shall be an
immediate distribution by a single payment of the entire account. It is intended by this paragraph 3. that distribution of the entire balance in the account of a Participant is to be made as soon as reasonably practicable after the death of a
Participant, or termination of employment by retirement or for any other reason and in no event shall distribution by reason of the Participant’s death be made later than five (5) years after the death of the Participant; provided, that if
the Participant’s account exceeds five thousand dollars ($5,000), it shall not be immediately distributed until the 

  

 -67- 








 
Participant attains age sixty-five (65) (which shall be considered the normal retirement age under the Plan and Code Section 411(a)(8)) without the
written consent of the Participant; but no consent to immediate distribution shall be required in the event of the death of a Participant, and such requirement of consent shall not give a Participant a right to any form or method of payment of
his/her account, and his/her account shall be maintained and distributed thereafter only in accordance with the rights to, and sequence of requested distribution stated in paragraphs 7. and 9. of this Article XI, below. Any such undistributed
balance of the Participant’s account shall be distributed upon his/her attaining age sixty-five (65); provided that a Participant, who has separated from employment with the Company by retirement or for any reason other than death, may make the
affirmative election to defer distribution of his/her account beyond age sixty-five (65) pursuant to paragraph 6. of this Article XI, below. 
  

	4.	Time of Distribution 

 Unless the Participant elects otherwise
pursuant to paragraph 6. of this Article XI, or as otherwise provided for under the Plan notwithstanding any other provisions of the Plan pursuant to the requirements of Code Section 401(a)(14) the payment of benefits under the Plan to the
Participant will begin not later than the sixtieth (60th) day after the latest of the close of the Plan Year in which: 
  

	 	1.	the Participant attains the age sixty-five (65), 

  

	 	2.	occurs the tenth (10th) anniversary of the year in which the Participant commenced participation in the Plan, or 

  

	 	3.	the Participant terminates employment with the Company. 

  

	5.	ESOP Stock Distributions 

 Notwithstanding any other provisions of
the Plan, the ONEOK, Inc. Common Stock in a Participant’s Account to which the Employee Stock Ownership Plan provisions of the Plan are applicable (hereinafter referred to as “ESOP Account Balance”), shall be distributed on the
earlier of (i) time when distribution would otherwise be made under the Plan, or (ii) if the Participant so elects, will be distributed commencing not later than one (1) year after the close of the Plan Year (I) in which the
Participant separates from service by reason of attainment of normal retirement age under the Plan, disability or death, or (II) which is the fifth (5th) Plan Year in which the Participant otherwise separates from service, except that this
clause (II) shall not apply if the Participant is reemployed by the Company before distribution is required to begin under this clause (II). If distribution of a Participant’s ESOP Account Balance is ever required to be made under clause
(ii) in the preceding sentence, then in such case, unless the Participant elects otherwise, the distribution of the Participant’s ESOP Account Balance will be in substantially equal periodic payments (not less frequently than annually)
over a period not longer than the greater of five (5) years, or in the case of a Participant with an Account balance in excess of Five Hundred Thousand Dollars ($500,000), five (5) years plus one (1) additional year (but not more than
five (5) additional years) for each One Hundred Thousand Dollars ($100,000) or fraction thereof by which such balance exceeds Five Hundred Thousand Dollars ($500,000), as such dollar amounts are adjusted for cost-of-living increases pursuant to
Code Sections  409(o)(2) and 415(d). The foregoing provisions of this paragraph 5 are intended to provide for distribution of a Participant’s ESOP Account Balance at least as soon as provided in Code Section 409(o) only if such form
and timing of distribution would be earlier than otherwise generally provided by the Plan. 
  

 -68- 









	6.	Participant Election to Defer Distribution 

 A Participant, whose
employment with the Company is terminated by retirement or for any reason other than death, may make an affirmative election to defer the distribution of his/her account if it exceeds five thousand dollars ($5,000) on the date of his/her retirement
or separation from service. Such affirmative election of deferral of distribution is separate and distinct from the requirement of consent to immediate distribution stated in paragraph 3. of this Article XI, and shall apply independently thereof. It
shall be made by written statement describing the Participant’s account in a form prescribed by the Committee, signed by the Participant and delivered by him/her to the Committee not later than sixty (60) days following the
Participant’s retirement or separation from service. 
 A Participant shall be deemed to have made such an affirmative election to defer the
distribution of his/her account in the absence of any such affirmative election after he/she has been advised in writing by the Committee of his/her rights under this paragraph 6, and paragraph 3 of this Article XI, upon termination of his/her
employment by retirement or for any other reason. 
  

	7.	Individual Retirement Account Distributions 

 In the event of
mandatory distribution greater than $1,000 in accordance with the provisions of Paragraph 3 of this Article XI or otherwise, if the Participant does not elect to have such distribution paid directly to an Eligible Retirement Plan specified by the
Participant in a direct rollover or to receive the distribution directly in accordance with Article V of the Plan, then the Committee shall cause the distribution to be paid in a direct rollover to an individual retirement account designated by the
Committee. 
  

	8.	Sequence of Deferred Distribution of Accounts 

 A. Subject to
subparagraph 7.B., below, if a Participant refuses consent to immediate distribution of his/her account under paragraph 3. of this Article XI, above, or a Participant makes the affirmative election of deferral of distribution provided in paragraph
6. of this Article XI, his/her account shall continue to be maintained in the Trust in the manner provided by the Plan. Subject to the prior approval and consent of the Committee, the Participant may at any time thereafter request in writing that
distribution of his/her account be made. When such a request is approved by the Committee, the Participant’s account shall be distributed to the Participant within a reasonable time following receipt and approval of that request; provided that
such a deferred distribution of a Participant’s account shall be only in the following sequence: first, either all of his/her account, or all of his/her Participant contributions; second, the balance of the account not previously distributed;
thus, all of a Participant’s contributions must be distributed to him/her at one time, and no Company contributions can be distributed without previous or concurrent distribution of all Participant contributions. A Participant who has withdrawn
all of his/her own contributions prior to deferral of distribution hereunder may thereafter request and receive only a single distribution of the balance of his/her account. No earnings credited to the account of a Participant can be distributed to
him/her after his/her termination of employment with the Company without liquidating the total account balance. 
  

 -69- 








 B. Notwithstanding the foregoing, a Participant (or former Employee) shall have the right to withdrawal of all or a
portion of that part of his/her Pre-1999 KGS 401(k) Thrift Plan Account of which distribution was deferred pursuant to the provisions of the KGS 401(k) Thrift Plan in accordance with those provisions, which are incorporated herein by reference.

whose employment with the Company is terminated shall in all events have any undistributed balance of his/her account paid and distributed to him/her not later than the later of (i) April 1 of the calendar year following the end of the
calendar year which he/she attains age 70 1/2 or (ii) the calendar year he/she retires, as provided for in paragraph 11 of
this Article XI, below. No deferral of distribution permitted or provided for under paragraph 3 or paragraph 6 of this Article XI shall take precedence over or prevent such required distribution. 
  

	10.	Distribution of Deferred Accounts at Death of Participant 

 If a
Participant who has refused to consent to immediate distribution under paragraph 3. of this Article XI, above, or who has made the affirmative election to defer receipt of his/her account under paragraph 6. of this Article XI, dies before a complete
distribution of the account has been made, then upon his/her death, his/her entire account balance shall be distributed to his/her surviving spouse, beneficiaries, or legatees in the same manner and within the same time periods following such death
as are provided for under paragraph 3. of this Article XI in the case of a Participant’s death prior to other termination of his/her employment with the Company. 
  

	11.	Required Distributions. 

 A. General Rules. 
  

	 	1.	Precedence. The requirements of this paragraph 11 of Article XI of the Plan will take precedence over any inconsistent provisions of the Plan. 

  

	 	2.	Requirements of Treasury Regulations Incorporated. All distributions required under this article will be determined and made in accordance with the Treasury regulations under
Code Section 401(a)(9). 

 B. Time and Manner of Distribution. 
  

	 	1.	Required Beginning Date. The Participant’s entire interest in the Plan will be distributed, or begin to be distributed, to the Participant no later than the

Participant’s entire interest in the Plan shall be distributed in a single lump sum distribution to the Participant’s Designated Beneficiary no later than one (1) year after the date of the Participant’s death. Notwithstanding
the foregoing, or any other provisions of this paragraph 11 and Code Section 401(a)(9) allowing a deferred time of distribution in event of the death of a Participant prior to distribution of the Participant’s entire interest in the Plan,
it is intended and directed that every distribution of a Participant’s account under the Plan on his/her death shall be made at least as rapidly as the immediate total distribution generally provided for under the Plan, without any deferral
allowed. 

 D. Required Distributions; Transferred Account. 
  

	 	1.	Application. This paragraph 11.D. shall be applicable instead of the general rule stated in paragraph 11.C., above, but only with respect to accounts of Participants that
constitute transferred accounts described and provided for in Articles XXII and XXIII of the Plan (“Transferred Account”). 

  

	 	2.	Required Distribution. 

  

	 	(a)	General. The entire interest of each Participant in a Transferred Account: 

  

	 	(1)	shall be distributed to such Participant not later than the Participant’s Required Beginning Date, or

	 	(b)	Distribution Where Participant Dies Before Entire Interest is Distributed. In the event of the death of a Participant before the entire interest of the Participant has been
distributed, the interest of the Participant shall be distributed in accordance with the following requirements: 

  

	 	(1)	If the distribution of a Participant’s interest has begun over the Participant’s life, or over the life or Life Expectancy of such Participant and a Designated

used as of the date of the Participant’s death. 

  

 -71- 









	 	(2)	If the Participant dies before the distribution of the Participant’s interest has begun in accordance with Paragraph 11.C,2.b.(1), above, the entire interest of the Participant
shall be distributed in the manner and form provided for under the Plan in such event, but no case later than: 

  

	 	(a)	within 5 years after the death of such Participant, or 

  

	 	(b)	If any portion of the Participant’s interest is payable to (or for the benefit of) a Designated Beneficiary pursuant to the provisions of the Plan, such portion shall be

shall begin not later than one (1) year after the Participant’s death or such later date as is prescribed in the Treasury regulations under Code Section 401(a)(9).

	12.	Form of Distributions 

 In so far as practicable, upon any complete
liquidation of a Participant’s account, upon distributions under paragraphs 7. or 8. of this Article XI, and upon withdrawals provided for in Article XII, any securities held in the account of the Participant will be distributed in kind if the
Participant so requests, but where this form of distribution is impracticable, cash will be paid in an amount equal to the value at the time of distribution, as determined by the Trustee, of any investment that it is impracticable to distribute in

	14.	Qualified Domestic Relations Orders; Distributions 

 Notwithstanding
any other provisions of the Plan, if a Participant’s account is ordered paid, transferred, or assigned, in whole or in part, to an alternate payee pursuant to an order determined by the Plan Administrator to be a Qualified Domestic Relations
Order within the meaning of Code Section 414(p), the payment and distribution to such alternate payee of amounts attributable to the Participant’s account shall be made by the Plan and Trustee in a single lump sum distribution, and such
distribution to such alternate payee shall be made pursuant to such a Qualified Domestic Relations Order prior to the date on which the Participant attains the earliest retirement age under the Plan, and within a reasonable period of time after such
determination, if such payment is otherwise permissible under Code Section 414(p). For purposes of this paragraph 14., the term “earliest retirement age” shall mean the earlier of (i) the date on which the Participant is entitled
to a distribution under the Plan, or (ii) the later of (a) the date the Participant attains age fifty (50), or (b) the earliest date on which the Participant could begin receiving benefits under the Plan if the Participant separated

foregoing provisions generally providing for immediate distribution.

 Subject to paragraph
10, and the limitations of paragraph 5. of this Article XII, below, a Participant may withdraw amounts from his/her 401(k) Contribution Account by submitting his/her written request to the Committee at such time and in such manner as shall be
prescribed by the Committee under the following conditions: 
 A. The withdrawal request must be on account of an immediate and heavy financial need
(sometimes hereinafter referred to as “hardship”) of the Participant and the withdrawal must be necessary to satisfy such hardship, all as determined by the Committee in accordance with the nondiscriminatory and objective standards
set forth herein. 
 B. No hardship withdrawal shall be made in an amount in excess of the amount of the immediate and heavy financial need of the
Participant. The amount of an 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 distribution. 
 C. No hardship withdrawal shall be permitted unless the Participant has obtained all distributions other than hardship distributions from the Company’s 401(k)
Contributions in the Participant’s Account, and has obtained all nontaxable loans currently available under all plans maintained by the Company. 
 D. A
withdrawal will be deemed to be made on account of an immediate and heavy financial need if it is on account of: 
  

	 	1.	Expenses for (or necessary to obtain) medical care that would be deductible under Code Section 213(d)(determined without regard to whether the expenses exceed 7.5% of adjusted
gross income described in Code Section 213(d) previously incurred by the Participant, the Participant’s spouse, or any dependents; 

  

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

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

  

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

  

	 	7.	Such other facts and circumstances as the Commissioner of Internal Revenue lists as deemed immediate and heavy financial needs through publication of regulations, revenue rulings,
notices, and other documents of general applicability. 

 E. Notwithstanding anything otherwise expressed or implied in the Plan, or under Code
Section 401(k), or the regulations under that section, a hardship distribution shall not be determined or allowed under the Plan on account of an event or condition of immediate and heavy financial need of a person who is a beneficiary of a
Participant under the Plan, unless such person, in addition to being such a beneficiary, also has a relationship of being the spouse or a dependent of the Participant that comes within the applicable terms and provisions of paragraph1.D, above; and
a hardship distribution shall not otherwise be allowed under the Plan for or with respect to circumstances of immediate and heavy financial need of a beneficiary of a Participant if such beneficiary is not either the spouse or a dependent of the
Participant.

 G. The hardship withdrawal, if approved by the
Committee, shall be paid to the Participant as soon as practicable following the date the Participant’s written request is submitted to the Committee. A hardship withdrawal for payment of tuition under subparagraph D.(3), above, may be made in
two (2) parts over the twelve (12) month period to conform the withdrawal to the amount of tuition determined to be needed by the student. 
 H. A
hardship withdrawal and distribution is not an eligible rollover distribution under Code Section 402(c) and the Plan shall be administered consistent with such classification and treatment.

	18.	Plan Loans 

 A. Loans shall be made available to all Participants
and beneficiaries on a reasonably equivalent basis. 
 B. Loans shall not be made available to Highly Compensated Employees, as defined in this Article I of
the Plan, in an amount greater that the amount made available to other employees. 
 C. Loans must be adequately secured and bear a reasonable rate of
interest. 
 D. No Participant loan shall exceed the present value of the Participant’s vested Accrued Benefit. No Participant loan may be made from a
Participant Roth Elective Deferral Account. 
 E. If a Participant Account is subject to Qualified Joint and Survivor Annuity requirements, a Participant
must obtain the consent of his or her spouse, if any, to use of the Participant’s Account Balance as security for the loan. Spousal consent shall be obtained no earlier than the beginning of the 90-day period that ends on the date on which the
loan is to be so secured. The consent must be in writing, must acknowledge the effect of the loan, and must be witnessed by a Plan representative or notary public. Such consent shall thereafter be binding with respect to the consenting spouse or any
subsequent spouse with respect to that loan. 
 F. In the event of default, foreclosure on the note and attachment of security will not occur until a
distributable event occurs in the Plan. 
 G. For Plan loans made before January 1, 2002, no loans will be made to any shareholder-employee or owner
employee. For purposes of this requirement, shareholder-employee means an employee or officer electing small business (Subchapter S) corporation who owns (or is considered as owning within the meaning of Code Section 318(a)(1)), on any day
during the taxable year of such corporation, more than 5% of the outstanding stock of the corporation. 
 H. Loan repayments will be suspended under the Plan
as permitted under Code Section 414(u)(4). 
 I. If a valid spousal consent has been obtained in accordance with paragraph 18.E., above, then
notwithstanding any other provision of the Plan, the portion of the Participant’s vested account balance used as a security interest held by the Plan by reason of a loan outstanding to the Participant shall be taken into account for purposes of
determining the amount of the Participant’s Account Balance payable at the time of death or distribution, but only if the reduction is used as repayment of the loan. If less than one hundred percent (100%) of the Participant’s vested
Account Balance (determined without regard to the preceding sentence) is payable to the surviving spouse, then the Participant’s Account Balance shall be adjusted by first reducing the vested Account Balance by the amount of the security used
as repayment of the loan, and then determining the benefit payable to the surviving spouse. 
  

 -81- 








 J. No loan to any Participant or beneficiary can be made to the extent that such loan when added to the outstanding
balance of all other loans to the Participant or beneficiary would exceed the lesser of (a) Fifty Thousand Dollars ($50,000) reduced by the excess (if any) of the highest outstanding balance of loans during the one year period ending on the day
before the loan is made, over the outstanding balance of loans from the plan on the date the loan is made, or (b) one-half of the present value of nonforfeitable Accrued Benefit of the Participant, or if greater, the total accrued benefit up to
Ten Thousand Dollars ($10,000). For purposes of the above limitation, all loans from all plans of the Company and other members of a group of employers described in Code Sections 414(b), 414(c) and 414(m) are aggregated. Furthermore, any loan shall
by its terms require that repayment (principal and interest) be amortized in level payments, not less frequently than quarterly, over a period not extending beyond five (5) years from the date of the loan, unless such loan is used to acquire a
dwelling unit which within a reasonable time (determined at the time the loan is made) will be used as the principal residence of the Participant. An assignment or pledge of any portion of the Participant’s interest in the Plan and a loan,
pledge, or assignment with respect to any insurance contract purchased by the Plan, will be treated as a loan under this paragraph. 
  

	19.	No Withdrawal of Loan Amount 

 A Participant to whom a loan has been
made pursuant to the provisions of paragraph 16. of this Article XII, shall not be allowed at any time to withdraw any amount from his/her Account in excess of the amount which is equal to the current value of his/her Account minus the outstanding
unpaid balance of such loan together with any accrued interest thereon.

 ARTICLE XIII. 
 BENEFICIARIES IN THE EVENT OF DEATH 
  

	1.	Surviving Spouse as Primary Beneficiary 

 A Participant’s
nonforfeitable Accrued Benefit (reduced by any security interest held by the Plan by reason of a loan outstanding to such Participant) shall be payable in full, on the death of the Participant, to the Participant’s surviving spouse, or if there
is no surviving spouse or the surviving spouse consents, in the manner provided in paragraph 2. of this Article XIII, below, then to a designated beneficiary of the Participant under paragraph 3. of this Article XIII. 
  

	2.	Election and Consent to Alternate Beneficiary or Beneficiaries 

 A
Participant may elect at any time to waive the required distribution and payment of his/her Account to his/her surviving spouse in the event of his/her death. Any such election must be made in writing by the Participant in the form prescribed by the
Committee. Any election by a Participant to waive the surviving spouse benefit may be revoked at any time by the Participant by a written declaration of revocation delivered to the Committee in such form as it may prescribe. Any election to waive
the surviving spouse benefit provided under paragraph 1. of this Article XIII above shall not take effect unless the spouse of the Participant consents in writing to such election, such election designates a beneficiary which may not be changed
without spousal consent (or the consent of the spouse expressly permits designations by the Participant without requirement of further consent by the spouse), and the spouse’s consent acknowledges the effect of such election and is witnessed by
a Plan representative or notary public; or it is established to the satisfaction of the Plan representative that the consent required of the spouse, as hereinabove provided, may not be obtained because the spouse cannot be located, or because of
such other circumstances as may be prescribed by Treasury regulations; provided, that any such consent by a spouse shall be effective only with respect to such spouse. 
  


	3.	Designation of Beneficiary or Beneficiaries 

 A Participant who has
no spouse, or who with his/her spouse’s consent has elected to waive the surviving spouse benefit as hereinabove provided, may file with the Committee, a written designation, in the form prescribed by the Committee, of the beneficiary or the
beneficiaries to receive all or part of his/her account upon his/her death, and the Participant shall also file with the Committee such information as to the identity of the beneficiary or beneficiaries and the relationship of the beneficiary or
beneficiaries to the Participant as the Committee may from time to time require. The last designation received by the Committee shall be controlling over any testamentary or other disposition; provided, however, that no designation, or change or
cancellation thereof, under this Plan shall be effective unless received by the Committee prior to the Participant’s death, and in no event shall it be effective as of a date prior to such receipt. 
  

 -83- 









	4.	Payment and Distribution to Beneficiary or Beneficiaries 

 Upon the
death of a Participant, his/her account shall be paid or distributed to the Participant’s spouse, or beneficiary or beneficiaries designated by him/her as provided in the preceding paragraphs 1. through 3. of this Article XIII, or, in the
absence of such designation, to the estate of the Participant or to the beneficiary or beneficiaries entitled thereto under the intestacy laws governing the disposition of his/her estate, and thereupon the Trustee, the Company, and the Committee
shall not be under any further liability to anyone. Provided, that the provisions for payment of a distribution to a surviving spouse of a deceased Participant in the KGS 401(k) Thrift Plan for a designated period of time shall remain in effect and
be applicable until such distribution is completed pursuant to such provisions. 
  

	5.	Rollover to IRA For Non-Spouse Beneficiary 

 Notwithstanding the
foregoing, a direct trustee-to-trustee transfer may be made of any portion of a distribution of the Plan Account of a deceased Participant or Employee to an individual retirement account established for the purpose of receiving the distribution on
behalf of an individual who is a designated beneficiary of the Participant or Employee and who is not the surviving spouse of the Participant or Employee pursuant to Code Section 402(c)(11).

	8.	Electronic Medium Notices and Elections; ERISA Disclosure and Reporting 

 A. The Plan may use an electronic medium to provide applicable notices and for the making of Participant elections. Any electronic system used by the Plan shall be reasonably designed to provide the information in any notice to an Employee,
Participant or other recipient in a manner that is no less understandable to the recipient than a written document. Such electronic system used by the Plan must be designed to alert the recipient. at the time a notice is provided, to the
significance of the information in the notice, and provide any instructions needed to access the notice, in a manner that is readily understandable. 
 B.
Except as otherwise provided herein, if electronic media is used by the Plan for a notice, the recipient must affirmatively consent to it electronically in a manner that reasonable demonstrates the recipient can access the notice, or by written
paper document but only if the recipient confirms the consent electronically in a manner that reasonably demonstrates such access to a notice. Each Employee, Participant or recipient must be provided a statement that he/she may have any notice
provided using a written paper document, may withdraw consent to electronic delivery, explains the procedure for such withdrawal, that he/she has a right to receive a paper copy of any notice delivered electronically, and the scope and effect of
his/her consent to electronic medium, update procedures, and hardware and software requirements. 
 C. As an alternative method of complying with a
requirement of an affirmative consent by a recipient of a notice to the use of an electronic medium and a requirement that a notice be in writing or in written form, the Plan may, if applicable, provide notice in and by use of a medium that a
recipient has the effective ability to access, and if in such case at the time the notice is provided the recipient must be advised that he/she may request and receive the notice in writing on paper at no charge, and, upon request, that such notice
shall be provided to the recipient at no charge. 
 D. Participant elections may be made under the Plan by an electronic medium if the person eligible to
make the election is effectively able to access the electronic medium. The electronic system used shall be reasonably designed to preclude any person other than the appropriate individual from making the election, and provide a reasonable
opportunity to review, confirm, modify or rescind the terms of the election before it becomes effective. The Participant or other individual making an election by electronic medium shall be provided, within a reasonable time, a confirmation of the
effect of the election through either a written paper document or an electronic medium satisfying the forgoing provisions of the Plan and applicable regulations. For Participant elections, including spousal consents that are required to be
witnessed, the signature or electronic witnessing or notarization may be made in accordance with applicable regulations governing electronic medium 
 The
foregoing provisions are intended to provide for the use of an electronic medium by the Plan in giving of notices and the making of elections to the extent and as allowed by applicable Treasury regulations, including Reg. §1.401(a)-21.

  

 -89- 








 E. The Plan may also furnish documents and disclose material pursuant to ERISA disclosure requirements to Participants,
beneficiaries and other individuals by and through electronic media. In the case of such disclosure through electronic media appropriate and necessary measures shall be taken to ensure the system used results in actual receipt, including return
receipt, notice of undelivered electronic mail features or other review to assure actual receipt. Use of such electronic media shall be done so as to protect confidentiality of Participant or beneficiary accounts or benefits, and to conform to the
form and content requirements of ERISA documents. The disclosure of documents pursuant to ERISA may be made to a Participant who has the ability to effectively access documents furnished in electronic form at any location where the Participant is
reasonably expected to perform his/her duties as an employee and access to the Company’s electronic information system used is an integral part of those duties. In addition, documents may be furnished by electronic media to any other
Participant, beneficiary or other individual who has affirmatively consented in electronic or non-electronic form to receiving documents by electronic media; provided, that prior to obtaining such consent the recipient is furnished a statement of
the documents involved, and of the right to and procedure for withdrawal of consent, the right to a paper document, and explanation of hardware and software requirements. Pursuant to the foregoing the Plan is intended to be administered in
accordance with the applicable ERISA regulations of the Department of Labor pertaining to electronic disclosure in 29 CFR §2520.104b-1. 
  

	9.	Recognition of Agency Relationships 

 The Trustee need not recognize
the agency of any party for an Employee or Participant unless it shall receive documentary evidence thereof satisfactory to it and thereafter from time to time, as the Trustee may determine, additional documentary evidence showing the continuance of
such agency; provided that the Trustee shall not be required to recognize any agency which the Trustee deems to be a device for violating the provisions of Article XVII. Until such time as the Trustee shall receive documentary evidence satisfactory
to it of the cessation or modification of any agency, the Trustee shall be entitled to rely upon the continuance of such agency and to deal with the agent as if he/she or it were the Employee or Participant. 
  

	10.	Valuation of Trust Assets 

 The Trustee shall value the assets of
the Plan Trust as of the close of the last day of the Plan Year, and more frequently, if directed by the Committee. The assets of the Trust shall be valued at their fair market value and the Committee shall, in accordance with a method consistently

 ARTICLE XVII. 
 NON-ASSIGNABILITY 

	1.	General 

 To the extent permitted by law, it is a condition of the
Plan, and all rights of each Participant shall be subject thereto, that no right or interest of any Participant in the Plan or in his/her account shall be assignable or transferable in whole or in part, either directly or by operation of law or
otherwise, including (but without limitation) execution, levy, garnishment, attachment, pledge, bankruptcy, or in any other manner, but excluding devolution by death or mental incompetency; and no right or interest of any Participant in the Plan or

 ARTICLE XXI. 
 TOP-HEAVY RULES 
  

	1.	Minimum Contribution 

 If this Plan is top-heavy in any Plan Year,
the Plan guarantees a minimum contribution of three percent (3%) of Compensation for each Non-key Employee who is a Participant employed by the Company on the last day of the Plan Year. If the contribution rate for the Key Employee with the
highest contribution rate is less than three percent (3%), the guaranteed minimum contribution for Non-key Employees under this paragraph 1. shall equal the highest contribution rate received by a Key Employee. The contribution rate is the sum of
Company contributions (not including Company contributions to Social Security) and any forfeitures allocated to the Participant’s Account for the Plan Year divided by his/her Compensation for the Plan Year taking into consideration amounts
contributed as a result of a salary reduction arrangement in determining the contributions made on behalf of Key Employees. All qualified defined contribution plans maintained by the Company shall be considered as a single plan for purposes of
determining the contribution rate. For any year in which the Plan is top-heavy, each Non-key Employee shall receive a minimum contribution if not separated from service at the end of the Plan Year regardless of whether such Non-key Employee has
declined to make any mandatory contribution otherwise required by the Plan. 
 If this Plan is top-heavy and any Participant in the Plan is a Participant in
any other top-heavy defined contribution plan(s) maintained by the Company, then this Plan shall provide the defined contribution plan minimum contribution for all such top-heavy defined contribution plans. 
 If any Participant in the Plan is also covered by a top-heavy defined benefit plan of the Company, the aggregate top-heavy minimum benefit requirement for such
Participant for all plans affected shall be satisfied by such Participant receiving a safe haven minimum defined contribution under this Plan equal to at least five percent (5%) of his/her Compensation for each Plan Year such plans are
top-heavy, all in accordance with and pursuant to the provisions of Treasury Regulations, §1.416-1, M-12, and any amendment thereto. 
  

	2.	Rate of Minimum Contribution 

 To the extent the contribution rate
with respect to a Non-key Employee for a Plan Year as described in paragraph 1. above, is less than the minimum contribution, the Company will increase its contribution for such Employee to the extent necessary so his/her contribution rate for the
Plan Year shall equal the guaranteed minimum contribution. The required additional contribution shall be made from net profits of the Company to the extent available, but if for a particular Plan Year there are no profits out of which to make
contributions to the Plan, the Company shall nevertheless make the minimum guaranteed contribution for each Non-key Employee. The Committee shall allocate the additional contribution to the account of the Non-key Employee for whom the Company makes
the contribution. 
  

 -97- 









	3.	Top-Heavy Status Determination 

 The Plan is top-heavy for a Plan
Year if the top-heavy ratio as of the Determination Date exceeds sixty percent (60%). The top-heavy ratio is a fraction, the numerator of which is the present value of the Accrued Benefit of all Key Employees as of the Determination Date, the
contributions due as of the Determination Date, and distributions made within the five (5)-year period immediately preceding the Determination Date, and the denominator of which is a similar sum determined for all Participants under this Plan;
provided, that if any individual has not performed services for the Company at any time during the five (5)-year period ending on the Determination Date, any accrued benefit for such individual (and on account of such individual) shall not be taken
into account. The foregoing determination of top-heaviness, and the top-heavy ratio shall also apply to distributions under a terminated plan which if it had not been terminated would have been required to be included in an aggregation group
including the Plan. The Committee shall calculate the top-heavy ratio without regard to any Non-key Employee who was formerly a Key Employee. The Committee shall calculate the top-heavy ratio, including the extent to which it must take into account
any distributions, rollovers, and other transfers, in accordance with Code Section 416 and the regulations thereunder. 
 If the Company maintains any
other qualified plans, this Plan is a top-heavy plan only if it is part of the Top-Heavy Aggregation Group, and the top-heavy ratio for both the Top-Heavy Aggregation Group and the Additional Aggregation Group exceeds sixty percent (60%). The
Committee shall calculate the top-heavy ratio and determine top-heavy status for the aggregation of plans for a particular year by the following procedures: 
 A. The present value of accrued benefits (including distribution to Key Employees) is determined separately for each plan as of each plan’s Determination Date; 
 B. The plans are then aggregated by adding together the results for each plan as of the Determination Dates for such plans that fall within the same calendar year, and 
 C. The combined results shall indicate whether or not the plans so aggregated are top heavy. 
  

	4.	Top-Heavy Contribution Limits 

 If the Plan is a top-heavy plan,
paragraphs 2(B) and 3(B) of Code Section 415(e) shall be applied by substituting “1.0” for “1.25” therein. Such substitution need not be made if the minimum contribution provided for under paragraph 1. of this Article XXI is
applied by substituting “four percent (4%)” for “three percent (3%)” therein, and if the Plan would not be a top-heavy plan if “ninety percent (90%)” were substituted for “sixty percent (60%)” wherever it
appears in paragraph 3. of this Article XXI. 
  

	5.	Vesting 

 The vesting in Plan benefits for Participants provided in
paragraph 1. of Article XI, shall be applicable to this Plan as a top-heavy plan. 
  

 -98-

 For purposes of the foregoing, subparagraph (C) of Code Section 318(a)(2) shall be applied by substituting
“five percent (5%)” for “fifty percent (50%);” the rules of Subsection (b), (c), and (m) of Code Section 414 shall not apply for purposes of determining ownership of the Company; and the term “compensation”
shall have the meaning given such term by Code Section 414(q)(7).

 G. “Additional Aggregation Group” means the Top-Heavy Aggregation Group plus any other qualified plans maintained by the Company, but only if such group would
satisfy in the aggregate the requirements of Code Sections 401(a)(4) and 410. The Committee shall determine which plan or plans to consider in determining the Additional Aggregation Group.

 ARTICLE XXII. 
 TRANSFERRED SUBSIDIARY PLAN ACCOUNTS 
  

	1.	General 

 If a Participant was a participant in a defined
contribution plan of a subsidiary of the Company that is subject to Code Sections 401(a)(11) and 417 with respect to that Participant, from which assets in which the Participant had a vested account and benefits have been transferred directly or
indirectly on or after January 1, 1985, to the Trust of this Plan pursuant to paragraphs 1. and 2. of Article V, that vested account and benefits (hereinafter referred to as “Transferred Participant Account”) of the Participant shall
be held, invested, maintained and distributed in accordance with this Article XXII. 
  

	2.	Separate Accounting and Accrual 

 A Participant’s Transferred
Participant Account shall be accounted for separately from all other of his/her contributions hereunder and the Company’s contributions to his/her regular Participant Account. The Participant’s rights in his/her accrued benefit derived
from his/her Transferred Participant Account shall be nonforfeitable, and any income and earnings therefrom and accretions thereon, shall be separately accounted for and become vested in such Participant immediately upon receipt thereof by the
Trustee of such income, earnings and accretions, and (subject to subsequent loss through decline in value of investments) and the Participant may not thereafter be deprived of such funds under any provision of the Plan. 
  

	3.	Other Plan Provisions Applicable 

 Except as otherwise provided in
this Article XXII, the Transferred Participant Account of any Participant shall be separately held, accounted for, and distributed, but in the same manner and subject to the same rules, requirements, and limitations as generally apply to a
Participant’s account under all provisions of this Plan. 
  

	4.	ONEOK Drilling Plan Transferred Account Annuity Conversion 

 Subject
to the provisions of paragraphs 5. through 10. of this Article XXII, below, a Participant who has a Transferred Participant Account from a transfer thereof to the Trust of this Plan from the trust of the ONEOK Drilling Company Profit-Sharing Thrift
Plan (“ONEOK Drilling Company Plan”) may elect distribution of such Transferred Participant Account in one (1) or a combination of (i) conversion of such Transferred Participant Account to annuities under a group annuity contract
of the type provided by the ONEOK Drilling Company Plan at the time of transfer of the Transferred Participant Account to the Trust of this Plan, if reasonably available, with distributions being made pursuant to the terms and conditions thereof and
in such amounts and for such durations as specified in said group annuity contract, or (ii) conversion of such Transferred Participant Account to annuities under an annuity contract or contracts selected and approved by the Committee with terms
and provisions comparable to such group annuity contract available under the ONEOK Drilling Company Plan at the time of such transfer, or (iii) payment in a single lump-sum. 
  

 -101- 









	5.	Distributions 

 Subject to paragraphs 8. and 9., below, the
Transferred Participant Account of a Participant shall not be distributed under a method of payment which, as of the Required Beginning Date, does not satisfy the minimum distribution requirements established by this Article XXII or paragraph 10. of
Article XI, or which is not consistent with Treasury regulations. The minimum distribution for a calendar year equals the Participant’s nonforfeitable accrued benefit in his/her Transferred Participant Account at the beginning of the year
divided by the Participant’s life expectancy or, if applicable, the life expectancy of such Participant and his/her designated beneficiary. For the purposes of this Article XXII, the “Required Beginning Date” shall mean the latest
date for distribution to a Participant stated in paragraph 10. of Article XI. In computing a minimum distribution, the life expectancy multiples under Treasury Regulations, Section 1.72-9 shall be used. For purposes of such computation, a
Participant’s life expectancy may be recalculated no more frequently than annually, but the life expectancy of a nonspouse beneficiary may not be recalculated. If the Participant’s spouse is not the designated beneficiary, the method of
distribution selected must provide that the present value of the payments to be made to the Participant is more than fifty percent (50%) of the present value of the total payments to the Participant and his/her beneficiaries. 
  

	6.	Consent of Distribution 

 A Participant and the spouse of the
Participant (or where the Participant has died, the surviving spouse) must consent to the form of the distribution of the Transferred Participant Account the Committee directs the Trustee to make if: (i) the present value of the
Participant’s nonforfeitable accrued benefit exceeds five thousand dollars ($5,000); (ii) the Qualified Joint and Survivor Annuity provisions stated below in this Article XXII apply to the distribution; and (iii) a distribution in a
form other than a Qualified Joint and Survivor Annuity is to be made. 
  

	7.	Time of Distribution 

 If distribution of a Participant’s Transferred Participant Account in other than lump-sum is authorized by this Article XXII, then upon the death of the Participant, the Participant’s Transferred Participant Account shall be paid
in accordance with this paragraph. If the Participant’s death occurs after payment of the Participant’s Transferred Participant Account has begun, payment thereof shall be completed over a period which does not exceed the payment period
which had commenced. If the Participant’s death occurs prior to the time payment of the Participant’s benefit from the Transferred Participant Account has begun, the payment thereof shall be made over a period not exceeding (i) five
(5) years after the date of the Participant’s death, or (ii) if the beneficiary is a designated beneficiary, over the designated beneficiary’s life expectancy; but payment of the Participant’s Transferred Participant Account
over a period described in (ii) shall not be made unless such payment to the designated beneficiary begins no later than one (1) year after the date of the Participant’s death or, if later, and the designated beneficiary is the
Participant’s surviving spouse, the date the Participant would have attained age seventy and one-half (70 1/2).

  

 -102- 









	8.	Qualified Joint and Survivor Annuity; Qualified Preretirement Survivor Annuity 

 For Plan Years beginning after December 31, 1984, the Committee shall direct the Trustee to distribute a married or unmarried Participant’s Transferred Participant Account, otherwise payable in annuity form,
in the form of a Qualified Joint and Survivor Annuity or a Qualified Preretirement Survivor Annuity, unless the Participant makes a valid election to waive the Qualified Joint and Survivor Annuity or Qualified Preretirement Survivor Annuity under
paragraph 9. of this Article XXII, below. 
 “A Qualified Joint and Survivor Annuity” is an annuity which is purchasable with the
Participant’s Transferred Participant Account and which is payable for the life of the Participant with, if the Participant is married on the Annuity Starting Date, a survivor annuity payable for the life of the Participant’s surviving
spouse equal to fifty percent (50%) of the amount of the annuity payable during the joint lives of the Participant and his/her spouse, and which is the actuarial equivalent of a single annuity for the life of the Participant. On or before the
Annuity Starting Date, the Committee, in its sole discretion without Participant or spousal consent, may direct the Trustee to pay the Participant’s Transferred Participant Account in a lump sum, in lieu of a Qualified Joint and Survivor
Annuity, if the present value of the Participant’s Transferred Participant Account (excluding accumulated deductible employee contributions) does not exceed five thousand dollars ($5,000). 
 If a married Participant dies before the Annuity Starting Date and such Participant has a surviving spouse, the Committee shall direct the Trustee to distribute the
Participant’s Transferred Participant Account to the Participant’s surviving spouse in the form of a Qualified Preretirement Survivor Annuity, unless the Participant has a valid waiver election in effect. A “Qualified Preretirement
Survivor Annuity” is an annuity which is actuarially equivalent to fifty percent (50%) of the Participant’s Transferred Participant Account (determined as of the date of the Participant’s death) and which is payable for the life
of the Participant’s surviving spouse. Any security interest held by reason of a loan outstanding to the Participant shall be taken into account in determining the amount of the Qualified Preretirement Survivor Annuity. The Participant’s
surviving spouse may elect to have the Trustee commence payment of the Qualified Preretirement Survivor Annuity within a reasonable period of time following the date of the Participant’s death. Furthermore, if the present value of the
Participant’s Transferred Participant Account exceeds five thousand dollars ($5,000), the Committee shall not direct the Trustee to distribute the Qualified Preretirement Survivor Annuity to the Participant’s surviving spouse prior to the
date the Participant would have attained age sixty-five (65) without the written consent of the surviving spouse. The Committee, in its sole discretion, may direct the Trustee to make a lump-sum distribution to the Participant’s surviving
spouse in lieu of a Qualified Preretirement Survivor Annuity, if the present value of the Participant’s Transferred Participant Account is not greater than five thousand dollars ($5,000). 
 If the Participant has in effect a valid waiver election regarding the Qualified Joint and Survivor Annuity or the Qualified Preretirement Survivor Annuity, the
Committee shall direct the Trustee to distribute the Participant’s Transferred Participant Account in accordance with paragraphs 3. and 4., above. For purposes of applying this Article XXII, the Committee shall treat a former spouse as the
Participant’s spouse or surviving spouse to the extent provided under a Qualified Domestic Relations Order (as defined in Code Section 414(p)). 
  

 -103- 









	9.	Notices; Waiver Election 

 Within the Applicable Notice Period with
respect to such Participant, the Company shall provide the Participant a written explanation of the terms and conditions of the Qualified Joint and Survivor Annuity, the Participant’s right to make and the effect of an election to waive the
Qualified Joint and Survivor Annuity form of benefit, the rights of the Participant’s spouse to consent to such a waiver election, and the right to make and the effect of a revocation of the Participant’s waiver election. A Participant may
elect at any time during the Applicable Election Period to waive the Qualified Joint and Survivor Annuity form of benefit. The Participant may revoke a waiver of the Qualified Joint and Survivor Annuity or make a new waiver at any time during the
Applicable Election Period. 
 The Annuity Starting Date for a distribution in a form other than a Qualified Joint and Survivor Annuity may be less than
thirty (30) days after receipt of the written explanation described in the preceding paragraph provided: (1) the Participant has been provided with information that clearly indicates that the Participant has at least thirty (30) days
to consider whether to waive the Qualified Joint and Survivor Annuity and elect (with spousal consent) to a form of distribution other than a Qualified Joint and Survivor Annuity; (2) the Participant is permitted to revoke any affirmative
distribution election at least until the Annuity Starting Date or, if later, at any time prior to the expiration of the 7-day period that begins the day after the explanation of the Qualified Joint and Survivor Annuity is provided to the
Participant; and (3) the Annuity Starting Date is a date after the date that the written explanation was provided to the Participant. 
 A married
Participant’s waiver election is not valid after December 31, 1984, unless (i) the Participant’s spouse (to whom the survivor annuity is payable under the Qualified Joint and Survivor Annuity) has consented in writing to the
waiver election, (ii) such election designates a beneficiary (or form of benefit) which may not be changed without spousal consent (or the consent of the spouse expressly permits designations by the Participant without any requirement of
further consent by the spouse), and (iii) the spouse’s consent acknowledges the effect of the election, and a notary public or the Company (or its Plan representative) witnesses the spouse’s consent. The spouse’s consent to a
waiver of the Qualified Joint and Survivor Annuity shall be irrevocable unless the Participant revokes the waiver election. 
 The Company may accept as
valid a waiver election which does not satisfy the spousal consent requirements, if the Company establishes the Participant does not have a spouse, the Company is not able to locate the Participant’s spouse, or other circumstances exist under
which the Treasury Regulations excuse the consent requirement. 
 Notwithstanding the foregoing, a Qualified Joint and Survivor Annuity and Qualified
Preretirement Survivor Annuity will not be provided unless the Participant and spouse had been married throughout the one-year period ending on the earlier of (i) the Participant’s Annuity Starting Date or (ii) the date of the
Participant’s death; except that if a Participant marries within one (1) year before the Annuity Starting Date, and the Participant and the Participant’s spouse in such marriage have been married for at least a one-year period ending
on or before the date of the Participant’s death, such Participant and such spouse shall be treated as having been married throughout the one-year period ending on the Participant’s Annuity Starting Date.

 With respect to any Participant’s Transferred Participant Account subject to paragraph 8., the Company shall provide
to each Participant, within the Applicable Notice Period with respect to such Participant in a manner consistent with Treasury Regulations, a written explanation of the terms and conditions of the Qualified Preretirement Survivor Annuity comparable
to the explanation of the Qualified Joint and Survivor Annuity required hereunder. If the Participant’s Transferred Participant Account is not subject to paragraph 8. above prior to the time the Company must provide the written explanation of
the Qualified Preretirement Survivor Annuity, the Company shall provide the written explanation within a reasonable period consistent with Treasury Regulations following the time the Participant’s Transferred Participant Account first is
subject to this Article XXII, but not later than the close of the second Plan Year following the Plan Year in which the Participant enters the Plan or first becomes subject to paragraph 8. A Participant may elect at any time during the Applicable
Election Period to waive the Qualified Preretirement Survivor Annuity form of benefit. A Participant may revoke a waiver of the Qualified Preretirement Survivor Annuity or make a new waiver at any time during the Applicable Election Period.

 A Participant’s waiver election of the Qualified Preretirement Survivor Annuity is not valid unless (i) the Participant makes the waiver
election no earlier than the first day of the Plan Year in which he/she attains age thirty-five (35), and (ii) after December 31, 1984, the Participant’s spouse (to whom the Qualified Preretirement Survivor Annuity is payable)
satisfies the consent requirements described above. The spouse’s consent to a waiver of the Qualified Preretirement Survivor Annuity is irrevocable unless the Participant revokes the waiver election. Irrespective of the time of election
requirement described in (i), if the Participant separates from service prior to the first day of the Plan Year in which he/she attains age thirty-five (35), the Company may accept a waiver election with respect to the Transferred Participant
Account attributable to his/her service prior to his/her separation from service.

 The term “Earliest Retirement Age” means the earliest date on which, under the Plan, the Participant could elect to receive retirement benefits with respect to his/her Transferred Participant Account. The

date of the enactment of the Retirement Protection Act of 1994, the present value of any distribution made before the earlier of (i) the later of the date an amendment to this Plan applying the rule for calculating present value first stated
above is adopted or made effective, or (ii) the first day of the first Plan Year beginning after December 31, 2000, the present value of any distribution shall be calculated by using the interest rate determined under the regulations of

of this Article XXIII, but no earlier than the expiration of the seven-day period that begins the day after the information required to be furnished pursuant to Paragraph 2(C) of this Part F, has been furnished to the Participant. 
 B. Unless a Participant (1) has attained age sixty-five, (2) has died (A) without leaving an Eligible Surviving Spouse or (B) with an election in
effect, pursuant to Paragraph 3(b) of this Part F, not to receive the standard death benefit set forth in Paragraph 3(a) of this Part F, or (3) consents to a distribution pursuant to Paragraph 1(a) of this Part F, and, if such Participant has
an Eligible Surviving Spouse, unless such Eligible Surviving Spouse consents (with such consent being irrevocable) in accordance with the requirements of section 417 of the Code and applicable Treasury regulations thereunder) within the ninety-day
period ending on the date payment of his/her benefit hereunder is to commence pursuant to Paragraph 1(a) of this Part F, his/her Annuity Starting Date shall be deferred to the date which is as soon as administratively feasible after the date the
Participant attains (or would have attained) age sixty-five, or such earlier date as the Participant (with the consent of his/her Eligible Surviving Spouse, if applicable) may elect by written notice to the Committee prior to such date. Consent of
the Participant’s Eligible Surviving Spouse under this Paragraph shall not be required if the Participant’s benefit is to be paid in the form of the standard benefit described in this part. The Committee shall furnish information pertinent

 C. A Participant’s Annuity Starting Date shall in no event be later than the sixtieth day following the close of the Plan Year during which such Participant attains, or would have attained, his/her Normal
Retirement Date or, if later, terminates his/her employment with the Company. 
  

 -110- 








 D. A Participant’s Annuity Starting Date shall be in compliance with the provisions of section 401(a)(9) of the Code
and applicable Treasury regulations and shall in no event be later than: 
  

	 	 1.
	 For Participants attaining age seventy and one-half (70 1/2) before January 1, 1999, April 1 of the calendar year following the calendar year in which such Participant attains the age of seventy and one-half
(70 1/2); 


  

	 	 2.
	 For Participants attaining age seventy and one-half (70 1/2) after December 31, 1998, April 1 of the calendar year following the later of (A) the calendar year in which such Participant attains the age of
seventy and one-half (70 1/2) or (B) the calendar year in which such Participant terminates his/her employment with the
Employer (provided, however, that clause (B) of this sentence shall not apply in the case of a Participant who is a “five-percent owner” (as defined in section 416 of the Code) with respect to the Plan Year ending in the calendar year
in which such Participant attains the age of seventy and one-half (70 1/2); and



  

	 	 3.
	 In the case of a benefit payable pursuant to Part E of this Article XXIII, (A) if payable to other than the
Participant’s spouse, the last day of the one-year period following the death of such Participant or (B) if payable to the Participant’s spouse, after the date upon which such Participant would have attained the age of seventy and
one-half (70 1/2), unless such surviving spouse dies before payments commence, in which case the Annuity Starting Date may not be
deferred beyond the last day of the one-year period following the death of such surviving spouse. 


 The preceding provisions of this Part F, notwithstanding, a Participant may not elect to defer the receipt of his/her benefit hereunder to the extent that such deferral creates a death benefit that is more than
incidental within the meaning of section 401(a)(9)(G) of the Code and applicable Treasury regulations thereunder. Further, in determining compliance with the provisions of section 401(a)(9) of the Code, the life expectancies of a Participant and the
Participant’s spouse shall not be recalculated after the Annuity Starting Date. Finally, a Participant (other than a Participant who is a “five-percent owner” (as defined in section 416 of the Code) with respect to the Plan Year
ending in the calendar year in which such Participant attains the age of seventy and one-half (70 1/2) who attains age
seventy and one-half (70 1/2) in calendar years 1996, 1997, or 1998 may elect to defer his/her Annuity Starting Date until
no later than April 1 of the calendar year following the later of (A) the calendar year in which such Participant attains the age of seventy and one-half (70 1/2
) or (B) the calendar year in which such Participant terminates his/her employment with the Employer, provided, that such election is made by the later of the end of the calendar year in which
such Participant attains age seventy and one-half (70 1/2) or December 31, 1997.

 E. Subject to the provisions of Subparagraph (D), a Participant’s Annuity Starting Date shall not occur unless the events
under Parts B, C, D and E of this Article XXIII entitling the Participant (or his/her beneficiary) to a benefit constitutes a distributable event described in section 401(k)(2)(B) of the Code and shall not occur while the Participant is employed by
the Employer or any Controlled Entity (irrespective of whether the Participant has become entitled to a distribution of his/her benefit pursuant to Part B, C, D, or E of this Article XXIII). 
  

 -111- 








 F. Subparagraphs (A), (B) and (C), above, notwithstanding, a Participant whose vested interest in his/her
Transferred NGC Account is $5,000 or more may elect to defer his/her Annuity Starting Date beyond the date specified in such subparagraphs, subject to the provisions of Subparagraph (D), above, by submitting to the Committee a written statement,
signed by the Participant, which describes the benefit and designates the date on which the payment of such benefit shall commence. 
  

	2.	Standard and Alternative Forms of Benefit for Participants 

 A. For
purposes of Parts B, C or E of this Article XXIII, the standard benefit for any Participant who is married on his/her Annuity Starting Date shall be a joint and survivor annuity. Such joint and survivor annuity shall be a commercial annuity which is
payable for the life of the Participant with a survivor annuity for the life of the Participant’s Eligible Surviving Spouse which shall be one-half of the amount of the annuity payable during the joint lives of the Participant and the
Participant’s Eligible Surviving Spouse. The standard benefit for any Participant who is not married on his/her Annuity Starting Date shall be a commercial annuity which is payable for the life of the Participant. 
 B. Any Participant who would otherwise receive the standard benefit may elect not to take his/her benefit in such form by executing the form prescribed by the Committee
for such election during the election period described in Subparagraph (C), below. Any election may be revoked and subsequent elections may be made or revoked at any time during such election period. Notwithstanding the foregoing, an election by a
married Participant not to receive the standard benefit as provided in Subparagraph (A), above, shall not be effective unless (1) the Eligible Surviving Spouse has consented thereto in writing (including consent to the specific designated
beneficiary to receive payments following the Participant’s death or to the specific benefit form elected, which designation or election may not subsequently be changed by the Participant without spousal consent) and such consent acknowledges
the effect of such election and is witnessed by a Plan representative (other than the Participant) or a notary public, or (2) the consent of such spouse cannot be obtained because the Eligible Surviving Spouse cannot be located or because of
other circumstances described by applicable Treasury regulations. Any such consent by such Eligible Surviving Spouse shall be irrevocable. 
 C. The
Committee shall furnish certain information, pertinent to the Subparagraph (B) election, to each Participant no less than thirty (30) days (unless such thirty-day period is waived by an affirmative election in accordance with applicable
Treasury regulations) and no more than ninety (90) days before his/her Annuity Starting Date. The furnished information shall include an explanation of (1) the terms and conditions of the standard benefit, (2) the Participant’s
right to elect to waive the standard benefit and the effect of such election, (3) the rights of the Participant’s Eligible Surviving Spouse, if any, (4) the right to revoke such election and the effect of such revocation, (5) a
general description of the eligibility conditions and other material features of the alternative forms of benefit available pursuant to Subparagraph (D), below, and (6) sufficient additional information to explain the relative values of such
alternative forms of benefit. The period of time during which a Participant may make or revoke such election shall be the ninety-day period ending on such Participant’s Annuity Starting Date provided that such election may also be revoked at
any time prior to the expiration of the seven-day period that begins the day after the information required to be furnished pursuant to this Paragraph has been furnished to the Participant. 
  

 -112- 








 D. For purposes of Parts B, C or D of this Article XXIII, the benefit for any Participant who has elected not to receive
the standard benefit shall be paid in one of the following alternative forms to be selected by the Participant or, in the absence of such election, by the Committee; provided, however, that the period and method of payment of any such form shall be
in compliance with the provisions of section 401(a)(9) of the Code and applicable Treasury regulations thereunder: 
  

	 	1.	A commercial annuity in the form of a single life annuity for the life of such Participant. 

  

	 	2.	A commercial annuity (a) for the joint lives of the Participant and any person designated by the Participant, (b) for a term certain (of 5, 10, or 15 years) and continuous
for the life of the Participant if he/she survives such term certain, or (c) for a term certain to the Participant and any designated beneficiary of the Participant if the Participant does not survive such term certain.


  

	 	3.	A lump sum. 

  

	 	4.	Periodic installment payments to such Participant for a term certain or, in the event of such Participant’s death before the end of such term certain, to his/her designated
beneficiary; provided, however, that such term certain shall not exceed the lesser of (i) ten years or (ii) the life expectancy of the Participant or the joint and last survivor expectancy of the Participant and his/her designated
beneficiary. Upon the death of a beneficiary who is receiving installment payments under this Paragraph, the remaining balance in the Participant’s Transferred NGC Account shall be paid as soon as administratively feasible, in one lump sum cash
payment, to the beneficiary’s executor or administrator or to his/her heirs at law if there is no administration of such beneficiary’s estate. 

 The Annuity Starting Date for a distribution in a form other than a survivor annuity may be less than thirty (30) days after receipt of the written explanation described in the preceding paragraph provided:
(1) the Participant has been provided with information that clearly indicates that the Participant has at least thirty (30) days to consider whether to waive the survivor annuity and elect (with spousal consent) to a form of distribution
other than a survivor annuity; (2) the Participant is permitted to revoke any affirmative distribution election at least until the Annuity Starting Date, or, if later, at any time prior to the expiration of the 7-day period that begins the day
after the explanation of the survivor annuity is provided to the Participant; and (3) the Annuity Starting Date is a date after the date that the written explanation was provided to the Participant. 
 E. If a Participant, who terminated his/her employment under circumstances such that he/she was entitled to a benefit pursuant to Parts B, C, or D, dies prior to his/her
Annuity Starting Date, the amount of the benefit to which he/she was entitled shall be paid pursuant to Paragraph 3 of this Part F, just as if such Participant had died while employed by the Employer except that his/her vested interest shall be
determined pursuant to Parts B, C, or D, whichever is applicable. 
  

 -113- 









	3.	Standard and Alternative Forms of Death Benefit 

 A. For purposes of
Part E, the standard death benefit for a deceased Participant who leaves an Eligible Surviving Spouse shall be a survivor annuity. Such survivor annuity shall be a commercial annuity which is payable for the life of such Eligible Surviving Spouse.

 B. Any Participant who would otherwise have his/her death benefit paid in the standard survivor annuity form may elect not to have his/her benefit paid in
such form by executing the beneficiary designation form prescribed by the Committee and filing same with the Committee, designating a primary beneficiary other than his/her Eligible Surviving Spouse or electing some form of payment other than a
survivor annuity. Any election may be revoked and subsequent elections may be made or revoked at any time prior to a Participant’s date of death. 
 C.
Subparagraph B., above, to the contrary notwithstanding: 
  

	 	1.	An election not to have the death benefit paid in the standard survivor annuity form as provided in Subparagraph A, above, shall not be effective unless (a) the Eligible
Surviving Spouse has consented thereto in writing and such consent (i) acknowledges the effect of such election, (ii) either consents to the specific designated beneficiary (which designation may not subsequently be changed by the
Participant without spousal consent) or expressly permits such designation by the Participant without the requirement of further consent by the spouse, and (iii) is witnessed by a Plan representative (other than the Participant) or a notary
public or (b) the consent of such spouse cannot be obtained because the Eligible Surviving Spouse cannot be located or because of other circumstances described by applicable Treasury regulations. Any such consent by such Eligible Surviving
Spouse shall be irrevocable. 

  

	 	2.	An election not to have the death benefit paid in the standard survivor annuity form may be made before the first day of the Plan Year in which a Participant attains the age of
thirty-five (35) only (a) after the Participant separates from service and only with respect to benefits accrued under the Plan before the date of such separation and (b) in the case of a Participant who has not separated from
service, if the Participant has been furnished the information described in Subparagraph D, with such election to become invalid upon the first day of the Plan Year in which the Participant attains the age of thirty-five (35), whereupon a new
election may be made by such Participant. 

 D. The Committee shall furnish certain information pertinent to the Subparagraph B election to
each Participant within the period beginning with the first day of the Plan Year in which he/she attains the age of thirty-two (32) (but no earlier than the date such Participant begins participation in the Plan) and ending with the later of
(1) the last day of the Plan Year preceding the Plan Year in which the Participant attains the age of thirty-five (35), or (2) a reasonable time after the Employee becomes a Participant. If a Participant separates from service before
attaining age thirty-five (35), such information shall be furnished to such Participant 

  

 -114- 








 
within the period beginning one year before the Participant separates from service and ending one year after such separation. Such information shall also be
furnished to a Participant who has not attained the age of thirty-five (35) or terminated employment, within a reasonable time after written request by such Participant. The furnished information shall include an explanation of (1) the
terms and conditions of the survivor annuity, (2) the Participant’s right to elect to waive the survivor annuity and the effect of such election, (3) the rights of the Participant’s Eligible Surviving Spouse, (4) the right
to revoke such election and the effect of such revocation, (5) a general description of the eligibility conditions and other material features of the alternative forms of benefit available pursuant to Subparagraph F, below, and
(6) sufficient additional information to explain the relative value of such alternative forms of benefit. 
 E. In the event a survivor annuity is to be
paid to a Participant’s Eligible Surviving Spouse, such Eligible Surviving Spouse may elect to receive the benefit in one of the alternative forms set forth in Subparagraph 3F. Within a reasonable time after written request by such Eligible
Surviving Spouse, the Committee shall provide to such Eligible Surviving Spouse a written explanation of such survivor annuity form and the alternative forms of payment which may be selected along with the financial effect of each such form.

 F. For purposes of Part E, the death benefit of a deceased Participant who is not survived by an Eligible Surviving Spouse or who has elected not to have
his/her death benefit paid in the standard survivor annuity form set forth in Subparagraph 3A. shall be paid to his/her designated beneficiary in one of the following alternative forms to be selected by such beneficiary or, in the absence of such
selection, by the Committee; provided, however, that the period and method of payment of any such form shall be in compliance with the provisions of section 401(a)(9) of the Code and applicable Treasury regulations thereunder: 
  

	 	1.	A commercial annuity in the form of a single life annuity for the life of the designated beneficiary. 

  

	 	2.	A lump sum. 

 G. If a deceased Participant who either is not survived by
an Eligible Surviving Spouse or has elected (with spousal consent) not to have his/her standard death benefit paid in the standard survivor annuity form set forth in Subparagraph 3A. does not have a valid beneficiary designation on file with
the Committee at the time of his/her death, the designated beneficiary or beneficiaries to receive such Participant’s death benefit shall be as follows: 
  

	 	1.	If a Participant leaves an Eligible Surviving Spouse, his/her designated beneficiary shall be such Eligible Surviving Spouse; 

  

	 	2.	If a Participant leaves no Eligible Surviving Spouse, his/her designated beneficiary shall be (a) such Participant’s executor or administrator or (b) his/her heirs at
law if there is no administration of such Participant’s estate. 

  

 -115- 









	4.	Cash-Out of Benefit 

 If a Participant terminates his/her employment
and his/her vested interest in his/her Transferred NGC Account is not in excess of $5,000, such Participant’s benefit shall be paid in one lump sum payment in lieu of any other form of benefit herein provided. Any such payment shall be made at
the time specified in Subparagraph 1A. of this Part F, without regard to the consent restrictions of Subparagraph 1B. of this Part F, and the election and spousal consent requirements of Paragraphs 2 and 3 of this Part F, except that a married
Participant’s death benefit shall be paid to his/her Eligible Surviving Spouse unless another beneficiary has been designated pursuant to the provisions of Subparagraph 3B. The provisions of this Paragraph shall not be applicable to a
Participant following his/her Annuity Starting Date. 
  

	5.	Direct Rollover Election 

 Notwithstanding any provision of the Plan
to the contrary that would otherwise limit a Distributee’s election under this Part F, a Distributee may elect, at the time and in the manner prescribed by the Committee, to have all or any portion of an Eligible Rollover Distribution (other
than any portion attributable to the offset of an outstanding loan balance of such Participant pursuant to the Plan’s loan procedure) paid directly to an Eligible Retirement Plan specified by the Distributee in a Direct Rollover. The preceding
sentence notwithstanding, a Distributee may elect a Direct Rollover pursuant to this Paragraph only if such Distributee’s Eligible Rollover Distributions during the Plan Year are reasonably expected to total $200 or more. Furthermore, if less
than 100% of the Participant’s Eligible Rollover Distribution is to be a Direct Rollover, the amount of the Direct Rollover must be $500 or more. Prior to any Direct Rollover pursuant to this Paragraph, the Committee may require the Distributee
to furnish the Committee with a statement from the plan, account, or annuity to which the benefit is to be transferred verifying that such plan, account, or annuity is, or is intended to be, an Eligible Retirement Plan. 
  

	6.	Benefits from Account Balances 

 With respect to any benefit payable
in any form pursuant to the Plan, such benefit shall be provided from the Transferred NGC Account balance(s) to which the particular Participant or beneficiary is entitled. 
  

	7.	Commercial Annuities 

 At the direction of the Committee, the
Trustee may pay any form of benefit provided hereunder other than a lump sum payment or a Direct Rollover pursuant to Paragraph 5 of this Part F by the purchase of a commercial annuity contract and the distribution of such contract to the
Participant or beneficiary. Thereupon, the Plan shall have no further liability with respect to the amount used to purchase the annuity contract and such Participant or beneficiary shall look solely to the company issuing such contract for such
annuity payments. All certificates for commercial annuity benefits shall be nontransferable, except for surrender to the issuing company, and no benefit thereunder may be sold, assigned, discounted, or pledged (other than as collateral for a loan
from the company issuing same). Notwithstanding the foregoing, the terms of any such commercial annuity contract shall conform with the time of payment, form of payment, and consent provisions of Paragraphs 1, 2, and 3 of this Part F.

	8.	Present Value Determinations 

 The present value of a qualified
joint and survivor annuity benefit or a qualified preretirement survivor annuity benefit shall be calculated by using the Applicable Mortality Table and the Applicable Interest Rate. For purposes of the preceding sentence the term “Applicable
Mortality Table” shall mean the table prescribed by the Secretary of Treasury, pursuant to Code Section 417(e)(3)(A)(i)(I) (or corresponding provision of any future federal tax code), and the term “Applicable Interest Rate” shall
mean the annual rate of the interest on 30-year Treasury securities for the month before the date of distribution or such other time as may be prescribed by Treasury Regulations under Code Section 417(e)(3)(A)(i)(II) (or corresponding provision
of any future federal tax code). Provided, notwithstanding the foregoing, for this Plan, which was adopted and in effect before the date of the enactment of the Retirement Protection Act of 1994, the present value of any distribution made before the
earlier of (i) the later of the date an amendment to this Plan applying the rule for calculating present value first stated above is adopted or made effective, or (ii) the first day of the first Plan Year beginning after December 31,
2000, the present value of any distribution shall be calculated by using the interest rate determined under the regulations of the Pension Benefit Guaranty Corporation for determining the present value of a lump sum distribution on plan termination
that were in effect on September 1, 1993, and by using the provisions of the Plan as in effect on the day before such date of enactment but only if such provisions of the Plan met the requirements of Code Section 417(e)(3) as in effect on
the day before such date of enactment. 
  

	9.	Unclaimed Benefits 

 In the case of a benefit payable on behalf of a
Participant, if the Committee is unable to locate the Participant or beneficiary to whom such benefit is payable, upon the Committee’s determination thereof, such benefit shall be forfeited. Notwithstanding the foregoing, if subsequent to any
such forfeiture the Participant or beneficiary to whom such benefit is payable makes a valid claim for such benefit, such forfeited benefit shall be restored to the Plan. 
  

	10.	Claims Review 

 A. In any case in which a claim for Plan benefits of
a Participant or beneficiary is denied or modified, the Committee shall furnish written notice to the claimant within ninety (90) days (or within 180 days if additional information requested by the Committee necessitates an extension of the
ninety-day period and the claimant is informed of such extension in writing within the original ninety-day period), which notice shall: 
  

	 	1.	State the specific reason or reasons for the denial or modification; 

  

	 	2.	Provide specific reference to pertinent Plan provisions on which the denial or modification is based; 

  

 -117- 









	 	3.	Provide a description of any additional material or information necessary for the Participant, his/her beneficiary, or representative to perfect the claim and an explanation of why
such material or information is necessary; and 

  

	 	4.	Explain the Plan’s claim review procedure as described in Subparagraph 10(b), below. 

 B. In the event a claim for Plan benefits is denied or modified, if the Participant, his/her beneficiary, or a representative of such Participant or beneficiary desires to have such denial or modification reviewed, he
must, within sixty (60) days following receipt of the notice of such denial or modification, submit a written request for review by the Committee of its initial decision. In connection with such request, the Participant, his/her beneficiary, or
the representative of such Participant or beneficiary may review any pertinent documents upon which such denial or modification was based and may submit issues and comments in writing. Within sixty (60) days following such request for review
the Committee shall, after providing a full and fair review, render its final decision in writing to the Participant, his/her beneficiary, or the representative of such Participant or beneficiary stating specific reasons for such decision and making
specific references to pertinent Plan provisions upon which the decision is based. If special circumstances require an extension of such sixty-day period, the Committee’s decision shall be rendered as soon as possible, but not later than one
hundred twenty (120) days after receipt of the request for review. If an extension of time for review is required, written notice of the extension shall be furnished to the Participant, beneficiary, or the representative of such Participant or
beneficiary prior to the commencement of the extension period.

nondiscriminatory manner. A withdrawal shall be deemed to be made on account of an immediate and heavy financial need of a Participant if the withdrawal is for:
