	 	4.2.	Unmatched Payroll Reduction Contributions. 

 A Participant who has elected to have 6% of his or her Compensation contributed by the Employer to the Plan under Section 4.1 may elect to have up to an additional 54% of his or her Compensation
contributed by the Employer to the Plan on a pre-tax or after-tax basis through payroll reductions. Each Participant shall elect in accordance with such procedures and processes as determined by the Plan Administrator in increments of 1% the
percentage of his or her Compensation under this Section to be credited to his or her account as described under 7.1. 
  

	 	4.3.	Maximum Payroll Reduction Contribution. 

 (a) The maximum amount which may be contributed to the Plan by a Participant on a pre-tax basis under Sections 4.1 and 4.2 and any other Qualified Plan maintained by the Employer in any calendar year is
limited to the amount prescribed under Section 402(g) of the Code with respect to such calendar year. If a Participant’s pre-tax contributions reach this maximum (and, if applicable, the amount determined under Section 4.3(b)), the
Employer shall continue making Participant contributions based upon the Participant’s election under Sections 4.1 and 4.2, however, such Participant contributions will be treated by the Plan Administrator as after-tax contributions for the
remainder of the calendar year. 
 (b) Notwithstanding subsection (a), Participants who are eligible to make
elective deferrals hereunder and who have attained or will attain age 50 before the close of the Plan Year shall be eligible to make catch-up contributions in accordance with, and subject to the limitations of, Section 414(v) of the Code. Such
catch-up contributions shall not be taken into account for purposes of the provisions of the Plan implementing the required limitations of Sections 402(g) and 415 of the Code. The Plan shall not be treated as failing to satisfy the provisions of the
Plan implementing the requirements of Section 401(k)(3), 410(b) or 416 of the Code, as applicable, by reason of the making of such catch-up contributions. 

  
 9 

	 	4.4.	Employer Matching Contributions. 

 The Employer will contribute to the Plan an amount equal to 100% of the amount by which each Participant elects to have his or her Compensation reduced under Section 4.1. Any contributions made
pursuant to this Section 4.4 shall be paid to the Trustee as soon as practicable following each pay date of the Participant. 
  

	 	4.5.	Performance Contributions. 

 In addition to any contributions made by the Employer pursuant to Section 4.4, the Employer will contribute an additional amount if the Employer meets certain performance targets established by the
Board on an annual basis. If the maximum performance target established by the Board for the Employer’s fiscal year is met, the Employer will contribute to the Plan on behalf of each Participant who is employed on the last day of such fiscal
year an amount equal to 6% of the Participant’s Pro-Rated Salary. If the Employer meets the minimum performance target established by the Board for the Employer’s fiscal year but does not meet the maximum performance target, the Employer
will contribute to the Plan on behalf of each eligible Participant who is employed on the last day of such fiscal year a percentage of such Participant’s Pro-Rated Salary to be determined by the Board (which percentage shall be less than 6% of
the Participant’s Pro-Rated Salary) based on the Employer’s overall performance in relation to the maximum and minimum performance target ranges. Any contributions paid on account of the performance of the Employer pursuant to this
Section 4.5 shall be paid to the Trustee as soon as practicable following the determination of whether the Employer has met or exceeded the applicable performance targets. Notwithstanding the foregoing, (i) if the Employer does not meet
the minimum performance target established by the Board for the Employer’s fiscal year, the Board may, in its sole discretion, authorize the Employer to contribute to the Plan on behalf of each eligible Participant who is employed on the last
day of such fiscal year a percentage of such Participant’s Pro-Rated Salary determined by the Board; and (ii) if the Employer exceeds the maximum performance target established by the Board for the Employer’s fiscal year, the Board
may, in its sole discretion, authorize the Employer to contribute to the Plan on behalf of each eligible Participant who is employed on the last day of such fiscal year an additional percentage of such Participant’s Pro-Rated Salary determined
by the Board. Notwithstanding anything herein to the contrary, a Participant shall not be entitled to a Performance Contribution under this Section 4.5 for the portion of any fiscal year during which such Participant is employed by an Employer
at the grade level of vice president or above. 
  

	 	4.6.	Elections. 

 Each
election by a Participant under Sections 4.1 and 4.2 shall be effective until suspended or amended. Each election shall be effective only when made in accordance with such procedures and processes as determined by the Plan Administrator. 

 

	 	4.7.	Changes In And Suspension Of Payroll Reductions. 

  

	 	4.7.1.	Changes In Payroll Reductions. 

 Each Participant’s payroll reduction percentage under Sections 4.1 and 4.2 shall continue in effect until the Participant shall change such percentage; provided,

  
 10 

 
however, that the Participant may elect to have his or her pre-tax payroll reduction percentage automatically increase in increments of 1%, 2% or 3% each year on a date specified by the
Participant, up to a maximum of 60% of Compensation. A Participant may at any time in his or her discretion change such percentage in accordance with such procedures and processes as determined by the Plan Administrator. 

 

	 	4.7.2.	Suspension Of Payroll Reductions. 

 A Participant may at any time suspend his or her contributions in accordance with such procedures and processes as determined by the Plan Administrator. 

 

	 	4.7.2.1.	Suspension Of Payroll Reductions During Government Or Military Service. 

Suspension of a Participant’s contributions shall be permitted during any period of military service, or of
government service approved by the Employer, regardless of the duration of such period. 
  

	 	4.7.2.2.	Resumption Of Payroll Reductions After Suspension. 

 Except as provided in Section 5.2, a Participant who has suspended his or her contributions under Section 4.7.2 may at any time resume his or her contributions in accordance with such procedures
and processes as determined by the Plan Administrator. 
  

	 	4.8.	Tax Deductions. 

 All
Employer contributions are made conditioned upon their deductibility for Federal income tax purposes under Section 404 of the Code. Amounts contributed by an Employer shall be returned to the Employer from the Plan by the Trustee under the
following circumstances: 
 (a) If a contribution was made by an Employer by a mistake of fact, the excess of the
amount of such contribution over the amount that would have been contributed had there been no mistake of fact shall be returned to the Employer within one year after the payment of the contribution; and 

(b) If an Employer makes a contribution which is not deductible under Section 404 of the Code, such contribution (but
only to the extent disallowed) shall be returned to the Employer within one year after the disallowance of the deduction. 

Earnings attributable to the contribution shall not be returned to the Employer, but losses attributable to such excess contribution
shall be deducted from the amount to be returned. In the event (a) or (b) above apply, the Employer will distribute any salary reduction amounts returned to the Employer (less any losses) to the Employees who elected to reduce their salary
by such amounts. 

  
 11 

	 	4.9.	Rollover Contributions And Transfers. 

 The Plan Administrator may direct the Trustee to accept from or on behalf of an Employee any cash which would constitute an eligible rollover distribution as defined in Section 402(c)(4) of the Code
from any of the following types of plans: 
 (a) a qualified plan described in Section 401(a) of the Code,
excluding after-tax contributions; 
 (b) a qualified annuity plan described in Section 403(a) of the Code,
excluding after-tax contributions; 
 (c) an annuity plan described in Section 403(b) of the Code, excluding
after-tax contributions; and 
 (d) a plan maintained by a state or local government or instrumentality thereof
as described in Section 457(b) of the Code. 
 The Plan Administrator may also direct the Trustee to accept from the
trustee of another Qualified Plan a direct transfer of cash or other assets which does not constitute an eligible rollover contribution. Notwithstanding the preceding sentence, the Trustee may not accept the direct transfer of any assets from any
Qualified Plan which would cause the Plan to be subject to the requirements of Section 401(a)(11) of the Code. Any contributions under this Section shall be segregated in a separate account and shall be fully vested at all times. Such amounts
shall not be considered as a contribution by a Participant for purposes of Sections 4.1 or 18.11. 
  

	 	4.10.	Retirement Contributions. 

For the Plan Years beginning on January 1, 2009, 2010 and 2011, the Employer will contribute to the Plan on behalf of each
Participant who: 
 (a) was a Participant in the Magnum Coal Company Defined Contribution Retirement Plan, as
defined therein, on December 31, 2008; 
 (b) was hired by Apogee Coal Company, LLC or Hobet Mining, LLC
prior to August 1, 2006; and

herein to the contrary, no further contributions shall be made by the Employer under this Section 4.10 for any Plan Year beginning after December 31, 2011. 
  

	 	4.11.	Transition Contributions. 

For the Plan Years beginning on January 1, 2009, 2010, 2011 and 2012, the Employer will contribute to the Plan on behalf of each
Participant who: 
 (a) satisfies the conditions set forth in Section 4.10(a) and (b); 

(b) is employed as an Employee on the last day of the Plan Year, provided, however, that this subsection (b) shall

herein to the contrary, no further contributions shall be made by the Employer under this Section 4.11 (i) for a Participant for any Plan Year in which the number of calendar years that, as of the last day of such Plan Year, have elapsed
since December 31, 1997 exceeds the years of service such Participant was credited with under the Arch Plan or Ashland Plan, or (ii) for any Participant for any Plan Year beginning after December 31, 2012.

 SECTION 5 - LOANS AND WITHDRAWALS 

 

	 	5.1.	Loans. 

 Upon the
application of a Participant in accordance with such procedures and processes as determined by the Plan Administrator, the Plan Administrator, as administrator of the loan program, in accordance with its uniform nondiscriminatory policy, shall
direct the Trustee to make a loan or loans to such Participant, provided, however, that no loan shall be made if immediately after the loan the unpaid balance of all loans by this Plan and all other plans maintained by the Controlled Group to the
Participant would exceed the lesser of: 
 (a) $50,000 or 

(b) 50% of the portion of the Participant’s accounts available for a loan under this Plan. 

Notwithstanding the foregoing, (i) the $50,000 limitation in (a) above shall be reduced by the highest outstanding balance for
the one-year period ending on the day before a new loan is made minus the outstanding balance of existing loans to the Participant on the date of the new loan, and (ii) loans shall not be available from a Participant’s After-Tax Matched
Account, After-Tax Unmatched Account, Company After-Tax Matching Account, Company Pre-Tax Matching Account, Performance Contribution Account, Retirement Contribution Account or Transition Contribution Account. 

 

	 	5.2.	Withdrawals. 

  

	 	5.2.1.	Regular Withdrawals. 

 A Participant in the employment of the Employer may, in accordance with such procedures and processes as determined by the Plan Administrator, make a withdrawal from his or her After-Tax Matched Account
which has been held by the Plan for 24 months or more, his or her Company After-Tax Matching Account which has been held by the Plan for 24 months or more, or his or her After-Tax Unmatched Account. A Participant must withdraw his or her entire
After-Tax Unmatched Account before withdrawing any amounts from his or her After-Tax Matched Account or Company After-Tax Matching Account. 
  

	 	5.2.2.	Special Withdrawals. 

 A Participant in the employment of the Employer may withdraw the entire amount in his or her After-Tax Matched Account (i.e., with no 24-month holdback) in accordance with such procedures and
processes as determined by the Plan Administrator. In the event of a withdrawal under this Section of any amounts from the Participant’s After-Tax Matched Account which have been held in such account for less than 24 months, the
Participant’s right to make contributions under the Plan shall be suspended for a period of six months following the Valuation Date following the month in which the special withdrawal is made. 

  
 15 

	 	5.2.3.	Hardship Withdrawals. 

 A Participant in the employment of the Employer may, in accordance with such procedures and processes as determined by the Plan Administrator, withdraw his or her contributions to his or her Pre-Tax
Matched Account or Pre-Tax Unmatched Account if the Participant demonstrates a substantial hardship to the Plan Administrator. The Plan Administrator will grant a distribution on account of hardship only if the distribution is made on account of an
immediate and heavy financial need of the Participant and is necessary to satisfy such financial need. 
  

	 	5.2.3.1.	Determination of Immediate and Heavy Financial Need. 

 A distribution will be deemed to be made on account of an immediate and heavy financial need of the Participant only if the distribution is on account of: 

(a) expenses for (or necessary to obtain) medical care deductible under Sections 213(a) and 213(d) of the Code
(determined without regard to whether the expenses exceed any applicable threshold amount of adjusted gross income); 
 (b) costs directly related to the purchase (excluding mortgage payments) of a principal residence of the Participant; 

(c) the payment of tuition, related educational fees and room and board expenses for up to the next 12 months of
post-secondary education for the Participant, the Participant’s Spouse, or the Participant’s children or dependents (as defined in Section 152 of the Code, without regard to Sections152(b)(1), (b)(2) and (d)(1)(B) of the Code);

 (d) payments necessary to prevent the eviction of the Participant from his or her principal residence or
foreclosure on the mortgage of the Participant’s principal residence; 
 (e) payments for burial or funeral
expenses for the Employee’s deceased parent, spouse, children or dependents (as defined in Code Section 152 without regard to Code Section 152(d)(1)(B)); or 

(f) expenses for the repair of damage to the Participant’s principal residence deductible as a casualty loss under
Code Section 165 (determined without regard to whether the loss exceeds 10% of adjusted gross income). 

  
 16 

	 	5.2.3.2.	Amount Necessary To Satisfy Financial Need. 

 A distribution will be deemed to be necessary to satisfy an immediate and heavy financial need of a Participant if the following requirements are satisfied: 

(a) The distribution is not in excess of the amount of the immediate and heavy financial need of the Participant (which
may include any amounts necessary to pay any federal, state or local income tax or penalties reasonably anticipated to result from the distribution); and 
 (b) The Participant has obtained all distributions, other than hardship distributions, and all nontaxable (at the time of the loan) loans currently available under all plans maintained by the Controlled
Group. 
 In addition a Participant who receives a hardship withdrawal will be unable to make pre-tax
contributions or after-tax contributions to the Plan or any other qualified or nonqualified plan of deferred compensation maintained by the Controlled Group, including stock option and stock purchase plans and a cash or deferred arrangement that is
part of a cafeteria plan within the meaning of Section 125 of the Code (but not the cafeteria plan itself), for a period of six months after the Valuation Date as of which the hardship distribution is made. 

 

	 	5.2.4.	 Age
59 1/2 Withdrawals. 

 A Participant in
the employment of the Employer who has attained age 59 1/2 may, in accordance with such procedures and processes as determined by the Plan Administrator, make a withdrawal from his or her Pre-Tax Unmatched Account, Pre-Tax Matched Account, Company Pre-Tax
Matching Account, Performance Contribution Account, Retirement Contribution Account and Transition Contribution Account. 
  

	 	5.2.5.	Rollover Withdrawal. 

 An Employee in the employment of the Employer may, in accordance with such procedures and processes as determined by the Plan Administrator, make a withdrawal from his or her Rollover Account. 

 

	 	5.2.6.	Withdrawal of Amounts Attributable to Prior Plan 

 Notwithstanding anything in Section 5.2 to the contrary, in the case of a Participant who was a Participant in the Magnum Coal Company 401(k) Plan (“Magnum Plan”), as defined therein, and
whose accounts under the Magnum Plan were transferred to this Plan: 
 (a) after 12 months of participation in
the Magnum Plan and this Plan, such a Participant in the employment of the Employer may, in accordance with such procedures and processes as determined by the Plan Administrator, withdraw all or part of any amounts attributable to contributions
credited to his or her After-Tax Contribution Account under the Magnum Plan, as defined therein; and 
 (b) such
a Participant in the employment of the Employer may, in accordance with such procedures and processes as determined by the Plan Administrator, withdraw all or part of any amounts attributable to vested contributions credited to his or her Company
Matching Account or Company 

  
 17 

 
Fixed Contribution Account under the Magnum Plan, as defined therein, if the Participant has participated in the Magnum Plan and this Plan for at least three consecutive years. 

  
 18 

 SECTION 6 - DISTRIBUTIONS OF EXCESS AMOUNTS 

 

	 	6.1.	Distribution Of Excess Elective Deferrals. 

 If a Participant’s elective deferrals for any calendar year exceed $16,500 (or such higher amount prescribed by applicable law), then the Participant may file an election form prescribed by the Plan
Administrator with the Employer designating in writing the amount of such excess elective deferrals to be distributed from this Plan. Any such election form must be filed with the Employer no later than the first March 1 following the close of
such calendar year in order for the Employer to act on it. If such an election form is timely filed, the Trustee shall distribute to the Participant the amount of such excess elective deferrals which the Participant has allocated to this Plan
(together with any income or less any loss allocable to such amount for such calendar year, as determined in accordance with Section 8, Code Section 402(g) and applicable Treasury Regulations) on or before the first April 15 following
the close of such calendar year. In the case of a Highly Compensated Employee, any matching contributions which were contributed on account of the elective deferrals being distributed will be forfeited, even if such matching contributions are
vested. For purposes of the preceding sentence, the income or loss allocable to such excess amount will be determined under such reasonable method as the Plan Administrator shall establish, provided the method does not discriminate in favor of
Highly Compensated Employees, is used consistently for all Participants and for all corrective distributions under the Plan for the Plan Year, and is used by the Plan for allocating income to Participants’ accounts. 

 

	 	6.2.	Limitations On Pre-Tax Contributions For Highly Compensated Employees. 

 The Plan Administrator is authorized to reduce to the extent necessary the maximum contributions under Sections 4.1 and 4.2 for Highly Compensated Employees, prior to the close of the Plan Year, if the
Plan Administrator reasonably believes that such reduction is necessary to prevent the Plan from failing both tests in Section 401(k)(3) of the Code. Such adjustments shall be made in accordance with such procedures and processes as determined
by the Plan Administrator. The Plan Administrator may implement rules limiting contributions under Sections 4.1 and 4.2 which may be made on behalf of some or all Highly Compensated Employees so that the limits of Section 401(k)(3) or 401(m)(2)
of the Code are satisfied. If for any Plan Year the Plan satisfies neither of the tests set forth in Code Section 401(k)(3), the Trustee shall be directed by the Plan Administrator to return to each Highly Compensated Employee his or her
portion of the excess contributions (plus the income or less the loss allocable to such excess contributions as determined in accordance with Section 8, Code Section 401(k) and applicable Treasury Regulations) for such Plan Year within 12
months after the last day of such Plan Year. A Highly Compensated Employee shall forfeit any matching contributions which were contributed on account of any portion of the excess contributions even if such matching contributions are vested. Each
Highly Compensated Employee’s portion of the excess contributions for a Plan Year shall be determined under a two step process. First, the aggregate amount of excess contributions shall be calculated. This shall be done by reducing the actual
deferral percentages of those Highly Compensated Employees with the highest actual deferral percentages to the extent necessary but not below the next highest level of actual deferral percentages. This process shall be repeated, to the extent
necessary, until the actual deferral percentage for the group of Highly Compensated Employees satisfies one of the tests set forth in Section 401(k)(3) of the Code. The aggregate amount of excess contributions shall be equal to

  
 19 

 
the sum of all such reductions. Second, the aggregate amount of excess contributions to be returned shall be allocated by reducing the pre-tax contributions of those Highly Compensated Employees
with the highest amount of pre-tax contributions to the extent necessary but not below the next highest amount of pre-tax contributions. This process shall be repeated, to the extent necessary, until all excess contributions to be returned shall be
allocated among the Highly Compensated Employees. The income or loss allocable to a Highly Compensated Employee’s portion of the excess contribution will be determined under such reasonable method as the Plan Administrator shall establish,
provided the method does not discriminate in favor of Highly Compensated Employees, is used consistently for all Participants and for all corrective distributions under the Plan for the Plan Year, and is used by the Plan for allocating income to
Participants’ accounts. 
 (a) Coordination With Distributions Of Elective Deferrals. If the Plan is
required to distribute both elective deferrals and excess contributions for a Plan Year, the Plan shall: 
 (1)
calculate and distribute the elective deferrals before determining the excess contributions to be distributed to Highly Compensated Employees; 
 (2) calculate the actual deferral percentage including the amount of excess elective deferrals distributed pursuant to (1) above; and 

(3) distribute excess contributions to Participants by reducing the excess contributions distributed to a Participant by
the amount of excess elective deferrals distributed to such Participant. 
 (b) Election To Make Additional
Contributions. Notwithstanding the above, in accordance with Treasury Regulation Section 1.401(k)-2(a)(6), the Company may elect, in lieu of all or a portion of the corrective distribution described above in this Section, to make additional
qualified nonelective contributions or qualified matching contributions which are treated as elective deferrals under the Plan and that, in combination with the elective deferrals, satisfy the actual deferral percentage test. Any such additional
qualified nonelective contributions will be credited to a Participant’s’ Pre-Tax Matched Account and shall be allocated to each Participant who is not a Highly Compensated Employee in an amount as determined by the Company and will be
contributed as a uniform percentage of such Participant’s Compensation for the Plan Year. Any such additional qualified matching contributions will be credited to a Participant’s Pre-Tax Matched Account and shall be allocated to each
Participant who is not a Highly Compensated Employee and will be contributed as a uniform percentage of the amount contributed by such Participant under Section 4.1. 

(c) Testing Year. The actual deferral percentage of Non-Highly Compensated Employees shall be determined as of the
Plan Year preceding the Plan Year for which the Plan must satisfy one of the tests in Code Section 401(k)(3). 

  
 20 

	 	6.3.	Limitations On Matching Contributions For Highly Compensated Employees. 

 The Plan Administrator is authorized to reduce to the extent necessary the maximum amount of matching contributions under Section 4.4 and after-tax contributions contributed on behalf of any Highly
Compensated Employee prior to the close of the Plan Year if the Plan Administrator reasonably believes that such adjustment is necessary to prevent the Plan from failing Code Section 401(m)(2). Such reduction shall be made in accordance with
such procedures and processes as determined by the Plan Administrator. Notwithstanding anything herein to the contrary, the tests in Code Section 401(m)(2) shall be treated as satisfied with respect to such matching contributions and after-tax
contributions to the Plan, or a portion of the Plan, if the Plan or such portion is a collectively bargained plan that automatically satisfies Code Section 410(b), in accordance with Treasury Regulation Sections 1.401(m)-1(b)(2) and
1.410(b)-2(b)(7). If for any Plan Year the Plan satisfies neither of the tests set forth in Code Section 401(m)(2), the Trustee shall be directed by the Plan Administrator to return to each Highly Compensated Employee his or her portion of the
excess aggregate contributions (plus the income or less the losses allocable to such excess aggregate contributions in accordance with Section 8, Code Section 401(m) and applicable Treasury Regulations) for such Plan Year within 12 months
after the last day of such Plan Year. Each Highly Compensated Employee’s portion of the excess aggregate contributions for a Plan Year shall be determined under a two step process. First, the aggregate amount of excess aggregate contributions
shall be calculated. This shall be done by reducing the actual contribution percentages of those Highly Compensated Employees with the highest actual contribution percentages to the extent necessary but not below the next highest level of actual
contribution percentages. This process shall be repeated, to the extent necessary, until the actual contribution percentage for the group of Highly Compensated Employees satisfies one of the tests set forth in Code Section 401(m)(2). The
aggregate amount of excess aggregate contributions shall be equal to the sum of all such reductions. Second, the aggregate amount of excess aggregate contributions to be distributed or forfeited shall be allocated by first reducing any after-tax
contributions and then any matching contributions made by or on behalf of Highly Compensated Employees with the highest total amount of after-tax contributions and matching contributions to the extent necessary but not below the next highest total
amount of after-tax contributions and matching contributions. This process shall be repeated, to the extent necessary, until all excess aggregate contributions to be distributed or forfeited shall be allocated among the Highly Compensated Employees.
A Highly Compensated Employee whose after-tax contributions are determined to be excess aggregate contributions shall forfeit any matching contributions which were contributed on account of such after-tax contributions, even if such matching
contributions are vested. The income or loss allocable to a Highly Compensated Employee’s portion of the excess aggregate contributions will be determined under such reasonable method as the Plan Administrator shall establish, provided the
method does not discriminate in favor of Highly Compensated Employees, is used consistently for all Participants and for all corrective distributions under the Plan for the Plan Year, and is used by the Plan for allocating income to
Participants’ accounts. 
 (a) Election To Make Additional Contributions. Notwithstanding the above,
in accordance with Treasury Regulation Section 1.401(m)-2(a)(6), the Company may elect, in lieu of all or a portion of the distribution described above, to either (i) make an additional qualified nonelective contribution that, in
combination with matching contributions and after-tax contributions for the Plan Year, satisfies the actual 

  
 21 

 
contribution percentage test or (ii) recharacterize elective contributions as matching contributions. Any such additional qualified nonelective contributions will be credited to a
Participant’s Pre-Tax Matched Account and shall be allocated to each Participant who is not a Highly Compensated Employee in an amount as determined by the Company and will be contributed as a uniform percentage of such Participant’s
Compensation for the Plan Year. 
 (b) The actual contribution percentage of Non-Highly Compensated Employees
shall be determined as of the Plan Year preceding the Plan Year for which the Plan must satisfy one of the tests in Code Section 401(m)(2). 
  

	 	6.4.	Definitions And Special Rules. 

 (a) All terms used in this Section 6 shall have the meaning given such terms in Code Sections 401(k) and 401(m) and the regulations thereunder. 

(b) Plan Restructuring. The Plan may be aggregated with another plan or disaggregated under
Section 1.401(k)-1(b)(4) and Section 1.401(m)-1(b)(4) of the Treasury Regulations for any Plan Year in order to pass the actual contribution percentage and actual deferral percentage tests set forth in this Section. 

(c) Special Rules For Early Participation. If the Company applies Section 410(b)(4)(B) of the Code in

	 	9.2.	Optional Method Of Distribution. 

 In lieu of distribution of his or her accounts in a lump sum, a Participant may elect in accordance with such procedures and processes as determined by the Plan Administrator to have his or her accounts
distributed in substantially equal payments over a period of time not less than 2 years and not more than 10 years. In the event that a Participant who elects this optional form of benefit dies before the entire amount in his or her accounts has
been distributed, distribution will continue to be made to such Participant’s surviving Spouse, if any, or designated beneficiary, unless such Participant’s surviving Spouse or beneficiary elects to receive such remaining amounts in a lump
sum. 
  

	 	9.3.	Required Minimum Distributions. 

 Notwithstanding anything to the contrary contained in the Plan, the entire interest of a Participant will be distributed in accordance with Section 401(a)(9) of the Code and the regulations
thereunder beginning no later than the Participant’s Required Beginning Date. Notwithstanding the other provisions of this Section, distributions may be made under a designation made before January 1, 1984, in accordance with section
242(b)(2) of the Tax Equity and Fiscal Responsibility Act (TEFRA) and the provisions of the Plan that relate to section 242(b)(2) of TEFRA. 
 (a) If the Participant dies before distributions begin, the Participant’s entire interest will be distributed, or begin to be distributed, no later than as follows: 

(1) If the Participant’s surviving Spouse is the Participant’s sole designated beneficiary, then distributions
to the surviving Spouse will begin by December 31 of the calendar year immediately following the calendar year in which the Participant died, or by December 31 of the calendar year in which the Participant would have attained age 70-1/2,
if later. 
 (2) If the Participant’s surviving Spouse is not the Participant’s sole designated
beneficiary, then distributions to the designated beneficiary will begin by December 31 of the calendar year immediately following the calendar year in which the Participant died. 

(3) If there is no designated beneficiary as of September 30 of the year following the year of the
Participant’s death, the Participant’s entire interest will be distributed by December 31 of the calendar year containing the fifth anniversary of the Participant’s death. 

  
 26 

 (4) If the Participant’s surviving Spouse is the Participant’s
sole designated beneficiary and the surviving Spouse dies after the Participant but before distributions to the surviving Spouse begin, this subsection, other than subsection (a)(1), will apply as if the surviving Spouse were the Participant.

 For purposes of this subsection, unless subsection (a)(4) applies, distributions are considered to begin on
the Participant’s Required Beginning Date. If subsection (a)(4) applies, distributions are considered to begin on the date distributions are required to begin to the surviving Spouse under subsection (a)(1). To the extent the Plan provides for
distributions in the form of annuities, if distributions under an annuity purchased from an insurance company irrevocably commence to the Participant before the Participant’s Required Beginning Date (or to the Participant’s surviving
Spouse before the date distributions are required to begin to the surviving Spouse under subsection (a)(1)), the date distributions are considered to begin is the date distributions actually commence. 

(b) Unless the Participant’s interest is distributed in the form of an annuity purchased from an insurance company or
in a single sum on or before the Required Beginning Date, as of the first distribution calendar year distributions will be made in accordance with subsections (c) and (d). To the extent the Plan provides for distributions in the form of
annuities, if the Participant’s interest is distributed in the form of an annuity purchased from an insurance company, distributions thereunder will be made in accordance with the requirements of Code Section 401(a)(9) and the Treasury
regulations. 
 (c) During the Participant’s lifetime, the minimum amount that will be distributed for each
distribution calendar year is the lesser of: 
 (1) the quotient obtained by dividing the Participant’s
account balance by the distribution period in the Uniform Lifetime Table set forth in section 1.401(a)(9)-9 of the Treasury regulations, using the Participant’s age as of the Participant’s birthday in the distribution calendar year; or

 (2) if the Participant’s sole designated beneficiary for the distribution calendar year is the
Participant’s Spouse, the quotient obtained by dividing the Participant’s account balance by the number in the Joint and Last Survivor Table set forth in section 1.401(a)(9)-9 of the Treasury regulations, using the Participant’s and
Spouse’s attained ages as of the Participant’s and Spouse’s birthdays in the distribution calendar year. 
 Required minimum distributions will be determined beginning with the first distribution calendar year and up to and including the distribution calendar year that includes the Participant’s date of
death. 
 (d) If the Participant dies on or after the date distributions begin and there is a designated
beneficiary, the minimum amount that will be distributed for each distribution calendar year after the year of the Participant’s death is the quotient obtained by dividing 

  
 27 

 
the Participant’s account balance by the longer of the remaining life expectancy of the Participant or the remaining life expectancy of the Participant’s designated Beneficiary,
determined as follows: 
 (1) The Participant’s remaining life expectancy is calculated using the age of
the Participant in the year of death, reduced by one for each subsequent year. 
 (2) If the Participant’s
surviving Spouse is the Participant’s sole designated beneficiary, the remaining life expectancy of the surviving Spouse is calculated for each distribution calendar year after the year of the Participant’s death using the surviving
Spouse’s age as of the Spouse’s birthday in that year. For distribution calendar years after the year of the surviving Spouse’s death, the remaining life expectancy of the surviving Spouse is calculated using the age of the surviving
Spouse as of the Spouse’s birthday in the calendar year of the Spouse’s death, reduced by one for each subsequent calendar year. 
 (3) If the Participant’s surviving Spouse is not the Participant’s sole designated beneficiary, the designated beneficiary’s remaining life expectancy is calculated using the age of the
beneficiary in the year following the year of the Participant’s death, reduced by one for each subsequent year. 
 If the Participant dies on or after the date distributions begin and there is no designated beneficiary as of September 30 of the year after the year of the Participant’s death, the minimum
amount that will be distributed for each distribution calendar year after the year of the Participant’s death is the quotient obtained by dividing the Participant’s account balance by the Participant’s remaining life expectancy
calculated using the age of the Participant in the year of death, reduced by one for each subsequent year. 
 (e)
If the Participant dies before the date distributions begin and there is a designated beneficiary, the minimum amount that will be distributed for each distribution calendar year after the year of the Participant’s death is the quotient
obtained by dividing the Participant’s account balance by the remaining life expectancy of the Participant’s designated beneficiary, determined as provided in subsection (d). If the Participant dies before the date distributions begin and
there is no designated beneficiary as of September 30 of the year following the year of the Participant’s death, distribution of the Participant’s entire interest will be completed by December 31 of the calendar year containing
the fifth anniversary of the Participant’s death. If the Participant dies before the date distributions begin, the Participant’s surviving Spouse is the Participant’s sole designated beneficiary, and the surviving Spouse dies before
distributions are required to begin to the surviving Spouse under subsection (a)(1), this Section will apply as if the surviving Spouse were the Participant. 
 (f) The following definitions shall apply for purposes of this Section: 
 (1) Designated beneficiary shall mean the individual who is designated as the beneficiary under the terms of the Plan and is the designated beneficiary under Code Section 401(a)(9) and section
1.401(a)(9)-1, Q&A-4 of the Treasury regulations. 

  
 28 

 (2) A distribution calendar year is a calendar year for which a minimum
distribution is required. For distributions beginning before the Participant’s death, the first distribution calendar year is the calendar year immediately preceding the calendar year which contains the Participant’s Required Beginning
Date. For distributions beginning after the Participant’s death, the first distribution calendar year is the calendar year in which distributions are required to begin under subsection (a). The required minimum distribution for the
Participant’s first distribution calendar year will be made on or before the Participant’s Required Beginning Date. The required minimum distribution for other distribution calendar years, including the required minimum distribution for
the distribution calendar year in which the Participant’s Required Beginning Date occurs, will be made on or before December 31 of that distribution calendar year. 

(3) Life expectancy means an individual’s life expectancy as computed by use of the Single Life Table in section
1.401(a)(9)-9 of the Treasury regulations. 
 (4) The Participant’s account balance is the account balance
as of the last valuation date in the calendar year immediately preceding the distribution calendar year (valuation calendar year) increased by the amount of any contributions made and allocated or forfeitures allocated to the account balance as of
dates in the valuation calendar year after the valuation date and decreased by distributions made in the valuation calendar year after the valuation date. The account balance for the valuation calendar year includes any amounts rolled over or
transferred to the Plan either in the valuation calendar year or in the distribution calendar year if distributed or transferred in the valuation calendar year. 
 (g) Notwithstanding the above provisions of this Section 9.3, a Participant or beneficiary who would have been required to receive required minimum distributions for 2009 but for the enactment of
Section 401(a)(9)(H) of the Code (“2009 RMDs”) and who would have satisfied that requirement by receiving distributions that are (1) equal to the 2009 RMDs or (2) one or more payments in a series of substantially equal
distributions (that include the 2009 RMDs) made at least annually and expected to last for the life (or life expectancy) of the Participant, the joint lives (or joint life expectancy) of the Participant and the Participant’s designated
beneficiary, or for a period of at least ten years (“Extended 2009 RMDs”), will receive those distributions for 2009 unless the Participant or beneficiary chooses not to receive such distributions. Participants and beneficiaries described
in the preceding sentence will be given the opportunity to elect to receive the distributions described in the preceding sentence. In addition, solely for purposes of applying the direct rollover provisions of the Plan, 2009 RMDs will be treated as
eligible rollover distributions.

(a) in the case of a Participant who is not a Five Percent Owner with respect to the Plan Year ending in the calendar year
in which the Participant attains age 70-1/2, the April 1 following the calendar year in which occurs the later of the date the Participant attains age 70-1/2 and the date on which the Participant terminates employment; or 

(b) in the case of a Participant who is a Five Percent Owner with respect to the Plan Year ending in the calendar year in
which the Participant attains age 70-1/2, the April 1 following the calendar year in which the Participant attains age 70-1/2. 
 Each Participant shall have the right to withdraw all or any portion of his or her accounts beginning on the April 1 following the calendar year in which the Participant reaches age 70-1/2.

 So long as The Uniformed Services Employment and Reemployment Rights Act of 1994 (“USERRA”) or any similar law shall remain in force, providing for reemployment rights for all persons in
military service, as therein defined, an employee who leaves the employment of the Employer for military service in the Armed Forces of the United States, as defined in such Act from time to time in force, shall, for all purposes of this Plan, be
considered as having been in the employment of the Employer, with the time of his or her service in the military credited to his or her Service; provided that upon such employee being discharged from the military service of the United States he or
she applies for re-employment with the Employer and takes all other necessary action to be entitled to, and to be otherwise eligible for, reemployment rights, as provided by USERRA, or any similar law from time to time in force. 

 

	 	13.1.1.	Rights With Respect To Payroll Reduction Contributions. 

 Any Employee who is reemployed while entitled to veterans’ reemployment rights under USERRA and who has either (i) suspended his or her contributions during military service, or (ii) made
less than the maximum amount of contributions permitted by this Section during his or her period of military service, shall be permitted to make the contributions described in Sections 4.1 and 4.2 to the Plan with respect to the period of his or her
military service during the period which begins on the Employee’s date of reemployment with the Employer and ends upon the earlier of: 
 (a) the period equal to three times the Employee’s period of military service; and 
 (b) five years. 
 The maximum amount of contributions which the
Employee can make during this period shall be the maximum amount of contributions that he or she would have been permitted to make to the Plan during the period of military service if the individual had continued to be employed by the Employer
during such period and received Compensation during such period equal to the Compensation the Employee would have received during the period of military service had the Employee worked for the Employer during such period. If the Compensation the
Employee would have received during the period was not reasonably certain, the Employee’s average Compensation from the Employer during the 12 month period immediately preceding the period of military service shall be deemed to be such
Compensation. 
 If the Employer makes a contribution under Section 4.4 during a period when an Employee
was on military leave of absence and if the Employee later returns to employment and makes the contributions described in Sections 4.1 and 4.2 for this period, the Employer shall make such matching contributions on behalf of the Employee as would
have been made had the Employee’s contributions actually been made during the period of his or her military service. 

  
 37 

	 	13.1.2.	Performance Contributions, Retirement Contributions and Transition Contributions. 

An Employee who is on a leave of absence on account of military service described in this Section which commenced during
the Plan Year, but before the last day of the Employer’s fiscal year ending in such Plan Year, will share in the allocation of Performance Contributions under Section 4.5 for such Plan Year, but will not share in such allocations for any
subsequent Plan Year ending before the Employee’s return from such military leave. If the Employee is reemployed while entitled to veterans’ reemployment rights under USERRA, the Employer shall make Performance Contributions under
Section 4.5, Retirement Contributions under Section 4.10 and Transition Contributions under Section 4.11 on behalf of the Employee for each partial and full Plan Year in the Employee’s period of military service for which the
Employee did not receive a contribution. Such contributions shall be equal to the amount of contributions which would have been made had the Employee continued to be employed by the Employer during such military service and shall be determined as
though the Employee received Compensation equal to the amount the Employee would have received if he or she were not in military service. If the Compensation the Employee would have received but for such military service is not reasonably certain,
the Employee’s average Compensation from the Employer during the 12-month period immediately preceding the period of military service shall be deemed to be such Compensation. 

 

	 	13.1.3.	Treatment Of Contributions. 

 Contributions under this Section will be taken into account for purposes of the limitations of Sections 402(g) or 415 in the year to which the contributions relate, not the year in which the contributions
are made. In addition, such contributions will not cause the Plan to be treated as failing to meet the requirements of Code Sections 401(a)(4), 401(a)(26), 401(k)(3), 401(m), 410(b) or 416. 

Notwithstanding any provision of this Plan to the contrary, contributions, benefits and service credit with respect to
qualified military service will be provided in accordance with Code Section 414(u). Loan repayments will be suspended under this Plan during a period of qualified military service as permitted under Code Section 414(u)(4). 

 

	 	13.1.4.	Death During Military Service 

 The surviving Spouse or other beneficiary of a Participant who dies while performing qualified military service, as defined in Section 414(u) of the Code, shall be entitled to any additional benefits
(other than benefit accruals relating to the period of qualified military service) provided under the Plan had the Participant resumed and then terminated employment on account of death. 

  
 38 

	 	13.2.	Maternity Or Paternity Absence. 

 In the case of any employee who is absent from work 
 (a) by reason
of the pregnancy of the individual, 
 (b) by reason of the birth of a child of the individual, 

(c) by reason of the placement of a child with the individual in connection with the adoption of such child by such
individual, or 
 (d) for purposes of caring for such child for a period beginning immediately following such
birth or placement, 
 the employee shall be credited with Days of Service following the date such absence begins until the first anniversary of
such date solely for purposes of determining whether a Break in Service has occurred. In order to receive credit under this Section, an employee must furnish to the Employer information establishing (i) that the absence from work is for one of
the reasons described in this Section and (ii) the number of days for which the employee was absent. 
  

	 	13.3.	Other Leaves Of Absence. 

An employee on an Employer-approved leave of absence not described in Section 13.1 above shall for all purposes of this Plan be
considered as having continued in the employment of the Employer for the period of such leave, provided that the employee returns to the active employment of the Employer before or at the expiration of such leave. Such approved leaves of absence
shall be given on a uniform, non-discriminatory basis in similar fact situations. 
 Notwithstanding any other provision of the
Plan, a Participant who is on an Employer-approved leave of absence will share in the allocations of Employer contributions under Section 4.5 for the Plan Year in which such leave of absence begins but will not share in such allocations for any
subsequent Plan Year ending before the Participant’s return from such leave of absence. 
  

	 	13.4.	Transfers. 

 In the event
that: 
 (a) a Participant is transferred to employment with a member of the Controlled Group in a status as a
non-Employee; or 
 (b) a person is transferred from employment with a member of the Controlled Group in a status
as a non-Employee to employment with the Employer under circumstances making such person an Employee; or 
 (c) a
person was employed by a member of the Controlled Group in a status as a non-Employee, terminated his or her employment and was subsequently employed by the Employer as an Employee; or 

  
 39 

 (d) a Participant was employed by the Employer as an Employee, terminated
his or her employment and was subsequently employed by a member of the Controlled Group in a status as a non-Employee; 
 then the following
provisions of this Subsection shall apply: 
 (a) transfer to employment with a member of the Controlled Group as
a non-Employee shall not be considered termination of employment with the Employer, and such transferred person shall continue to be entitled to the benefits provided in the Plan, as modified by this Section; 

(b) employment with a member of the Controlled Group by a non-Employee will be deemed to be employment by the Employer,
but only with respect to employment during any period that such member of the Controlled Group is required to be aggregated with the Company pursuant to Code Sections 414(b), (c) or (m); 

(c) amounts earned from a member of the Controlled Group by a non-Employee shall not constitute Compensation hereunder;

 (d) termination of employment with a member of the Controlled Group which has not adopted the Plan by a person
entitled to benefits under this Plan (other than to transfer to employment with another member of the Controlled Group) shall be considered as termination of employment with the Employer; 

(e) all other terms and provisions of this Plan shall fully apply to such person and to any benefits to which he or she
may be entitled hereunder. 
 Notwithstanding anything in this Plan to the contrary, a Participant who is no longer employed by
a member of the Controlled Group which includes the Company as a member shall be considered a terminated Employee. 

Notwithstanding anything to the contrary in the Plan, a transfer from the status of an employee of the Employer to that of a leased
employee (as defined in Section 414(n) of the Code, without regard to Section 414(n)(2)(B)) shall not be considered a termination of employment under the Plan. An individual who has such a transfer shall not have a termination of
employment until he or she ceases to be an employee of the Employer and all members of the Controlled Group and is no longer a leased employee. 
  

	 	13.5.	Acquisition of Assets. 

If on or after January 1, 2010 the Employer acquires the assets (through purchase, merger or otherwise) of any other entity and
hires individuals who had been employed by such entity, the division or the subgroup in which such individuals are employed shall be excluded from the groups included in the definition of “Employee” unless the Employer communicates to such
division or subgroup is entitled to benefits under the Plan. 

  
 40 

 SECTION 14 - TRUSTEE 

The Company shall select a Trustee to hold and administer the assets of the Plan and shall enter into a trust agreement with such
Trustee. The Company may change the Trustee from time to time subject to the terms of the trust agreement. 

  
 41 

 SECTION 15 - ADMINISTRATION 

 

	 	15.1.	Plan Administrator. 

 The
Company shall be the Plan Administrator of the Plan within the meaning of ERISA and, except as otherwise specifically set forth herein, shall be solely responsible for and have sole control of the operation and administration of the Plan and the
establishment of such procedures and processes as may be necessary for the efficient operation and administration of the Plan. 
  

	 	15.2.	Construction. 

 The Plan

	 	15.3.	Delegation By The Plan Administrator. 

 The Plan Administrator may appoint such agents as it may deem necessary for the effective exercise of its duties, and may, to the extent not inconsistent herewith, delegate to such agents any powers and
duties, both ministerial and discretionary, as the Plan Administrator may deem expedient or appropriate. 
  

	 	15.4.	Duties Of The Plan Administrator. 

 The Plan Administrator shall, as part of its general duty to supervise and administer the Plan, direct the Trustee specifically in writing in regard to: 

(a) distribution payments, including the names of the payees, the amounts to be paid and the time or times when payments
shall be made; 
 (b) any other payments which the Trustee is not authorized to make without direction in writing
by the Plan Administrator; and 
 (c) preparation of an annual report for the Company, as of the end of each Plan
Year, in such form as the Company may require. 
  

	 	15.5.	Records Of The Plan Administrator. 

 All acts and determinations of the Plan Administrator shall be duly recorded, and all such records, together with such other documents as may be necessary for the proper administration of the Plan, shall

 43 

 SECTION 16 - CLAIM PROCEDURE 

 

	 	16.1.	Claim. 

 A Participant,
beneficiary or other person who believes that he or she is being denied a benefit to which he or she is entitled (hereinafter referred to as “Claimant”), or his or her duly authorized representative, may file a written request for such
benefit with the Director of Benefits setting forth his or her claim. The request must be addressed to: 
 Director of Benefits

 Patriot Coal Corporation 401(k) Retirement Plan 
 12312 Olive Boulevard 
 St. Louis, Missouri 63141 

Notwithstanding anything in the Plan to the contrary, a claim must be filed within one year from the date such claim first accrues or
the Claimant will be forever barred from pursuing such claim. A claim by a Claimant shall be deemed to have accrued on the earlier of (i) the date the Claimant’s benefits commence or (ii) the date the Claimant becomes aware, or should
have become aware, that his or her position regarding his or her entitlement to benefits is different from the Plan’s or the Employer’s position regarding the Claimant’s entitlement to benefits. 

 

	 	16.2.	Claim Decision. 

 Upon
receipt of a claim, the Director of Benefits shall advise the Claimant that a reply will be forthcoming within a reasonable period of time, but ordinarily not later than 90 days, and shall, in fact, deliver such reply within such period. However,
the Director of Benefits may extend the reply period for an additional 90 days for reasonable cause. If the reply period will be extended, the Director of Benefits shall advise the Claimant in writing during the initial ninety-day period indicating
the special circumstances requiring an extension and the date by which the Director of Benefits expects to render the benefit determination. If the claim is denied in whole or in part, the Director of Benefits will render a written opinion, using
language calculated to be understood by the Claimant, setting forth: 
 (a) the specific reason or reasons for
the denial; 
 (b) the specific references to pertinent Plan provisions on which the denial is based; 

(c) a description of any additional material or information necessary for the Claimant to perfect the claim and an
explanation as to why such material or such information is necessary; 
 (d) appropriate information as to the
steps to be taken if the Claimant wishes to submit the claim for review, including a statement of the Claimant’s right to bring a civil action under Section 502(a) of ERISA following an adverse benefit determination on review; and

  
 44 

 (e) the time limits for requesting a review of the denial under
Subsection 16.3 hereof and for the actual review of the denial under Subsection 16.4 hereof. 
  

	 	16.3.	Request For Review. 

Within 60 days after the receipt by the Claimant of the written opinion described above, the Claimant may request in writing that the
Committee review the Director of Benefits’ prior determination. Such request must be addressed to: 
 Committee 

Patriot Coal Corporation 401(k) Retirement Plan 
 12312 Olive Boulevard 
 St. Louis, Missouri 63141 

The Claimant or his or her duly authorized representative may submit written comments, documents, records or other information relating
to the denied claim, which such information shall be considered in the review under this subsection without regard to whether such information was submitted or considered in the initial benefit determination. The Claimant or his or her duly
authorized representative shall be provided, upon request and free of charge, reasonable access to, and copies of, all documents, records and other information which (i) was relied upon by the Director of Benefits in making its initial claims
decision, (ii) was submitted, considered or generated in the course of the Director of Benefits making its initial claims decision, without regard to whether such instrument was actually relied upon by the Director of Benefits in making its
decision or (iii) demonstrates compliance by the Director of Benefits with its administrative processes and safeguards designed to ensure and to verify that benefit claims determinations are made in accordance with governing Plan documents and
that, where appropriate, the Plan provisions have been applied consistently with respect to similarly situated claimants. If the Claimant does not request a review of the Director of Benefits’ determination within such 60-day period, he or she
shall be barred and estopped from challenging such determination. 
  

	 	16.4.	Review Of Decision. 

Within a reasonable period of time, ordinarily not later than 60 days, after the Committee’s receipt of a request for review, it
will review the Director of Benefits’ prior determination. If special circumstances require that the 60-day time period be extended, the Committee will so notify the Claimant within the initial 60-day period indicating the special circumstances
requiring an extension and the date by which the Committee expects to render its decision on review, which shall be as soon as possible but not later than 120 days after receipt of the request for review. In the event that the Committee extends the
determination period on review due to a Claimant’s failure to submit information necessary to decide a claim, the period for making the benefit determination on review shall not take into account the period beginning on the date on which
notification of extension is sent to the Claimant and ending on the date on which the Claimant responds to the request for additional information. The Committee has discretionary authority to determine a Claimant’s eligibility for benefits and
to interpret the terms of the Plan. Benefits under the Plan will be paid only if the Committee decides in its discretion that the Claimant is entitled to such benefits. The decision of the Committee shall be final and non-reviewable, unless found to
be arbitrary and capricious by a court of competent review. 

  
 45 

 
Such decision will be binding upon the Employer and the Claimant. If the Committee makes an adverse benefit determination on review, the Committee will render a written opinion, using language
calculated to be understood by the Claimant, setting forth: 
 (a) the specific reason or reasons for the denial;

 (b) the specific references to pertinent Plan provisions on which the denial is based; 

(c) a statement that the Claimant is entitled to receive, upon request and free of charge, reasonable access to, and
copies of, all documents, records and other information which (i) was relied upon by the Committee in making its decision, (ii) was submitted, considered or generated in the course of the Committee making its decision, without regard to
whether such instrument was actually relied upon by the Committee in making its decision or (iii) demonstrates compliance by the Committee with its administrative processes and safeguards designed to ensure and to verify that benefit claims
determinations are made in accordance with governing Plan documents, and that, where appropriate, the Plan provisions have been applied consistently with respect to similarly situated claimants; and 

(d) a statement of the Claimant’s right to bring a civil action under Section 502(a) of ERISA following the
adverse benefit determination on such review. 
  

	 	16.5.	Disability Determinations. 

 Notwithstanding anything herein, if a Claimant is denied a benefit because he or she is determined not to be disabled under Section 10.2(b) and he or she makes a claim pursuant to such denial, the
provisions of this 16.5 shall apply. Upon receipt of a claim, the reply period shall be forty-five (45) days. If, prior to the end of such 45-day period, the claims reviewer determines that, due to matters beyond the control of the Plan, a
decision cannot be rendered, the period for making the determination may be extended for up to thirty (30) days, and the claims reviewer shall notify the Claimant, prior to the expiration of such 45-day period, of the circumstances requiring an
extension and the date by which the Plan expects to render a decision. If, prior to the end of the first 30-day extension period, the claims reviewer determines that, due to matters beyond the control of the Plan, a decision cannot be rendered
within that extension period, the period for making the determination may be extended for up to an additional thirty (30) days, and the claims reviewer shall notify the Claimant, prior to the expiration of the first 30-day extension period, of
the circumstances requiring the extension and the date by which the Plan expects to render a decision. In the case of any extension described in this paragraph, the notice of extension shall specifically explain the standards on which entitlement to
a benefit is based, the unresolved issues that prevent a decision on the claim and the additional information needed to resolve those issues, and the Claimant shall be afforded forty-five (45) days within which to provide the specified
information. If information is requested, the period for making the benefit determination shall be tolled from the date on which notification of an extension is sent to the Claimant until the date on which the Claimant responds to the request for
information. 
 Within one hundred eighty (180) days after receiving the written notice of an adverse disposition of the
claim, the Claimant may request in writing, and shall be entitled to, a 

  
 46 

 
review of the benefit determination. In deciding an appeal of any adverse benefit determination that is based in whole or in part on a medical judgment, the Plan shall consult with a health care
professional who has appropriate training and experience in the field of medicine involved in the medical judgment. Such health care professional shall be an individual who is neither an individual who was consulted in connection with the adverse
benefit determination that is the subject of the appeal nor the subordinate of any such individual. The medical or vocational experts whose advice was obtained on behalf of the Plan in connection with the Claimant’s adverse benefit
determination will be identified to the Claimant. If the Claimant does not request a review within one hundred eighty (180) days after receiving written notice of the original’s disposition of the claim, the Claimant shall be deemed to
have accepted the original written disposition. 
 A decision on review shall be rendered in writing by the Plan within a
reasonable period of time, but ordinarily not later than forty-five (45) days after receipt of the Claimant’s request for review by the Plan, unless the Plan determines that special circumstances require an extension of time for processing
the claim. If the Plan determines that an extension of time for processing is required, written notice of the extension shall be furnished to the Claimant prior to the termination of the initial forty-five (45) period. In no event shall such
extension exceed a period of forty-five (45) days from the end of the initial period. The extension notice shall indicate the special circumstances requiring an extension of time and the date by which the Plan expects to render the
determination on review. In the event the extension is due to a Claimant’s failure to submit information necessary to decide the claim, the Claimant shall be afforded forty-five (45) days within which to provide the specified information,
and the period for making the benefit determination on review shall be tolled from the date on which notification of the extension is sent to the Claimant until the date on which the Claimant responds to the request for additional information.

 In the case of an adverse benefit determination on review, in addition to the information described in this Section, the
notice shall state: “You and your Plan may have other voluntary alternative dispute resolution options, such as mediation. One way to find out what may be available is to contact your local U.S. Department of Labor Office and your State
insurance regulatory agency.” 
  

	 	16.6.	Venue of Litigation. 

 In
light of the Plan Administrator’s substantial contacts with the State of Missouri, the fact that the Plan Administrator resides in Missouri and the Company is headquartered in St. Louis, Missouri, and the Company’s establishment of, and
the Plan Administrator’s maintenance of, this Plan in Missouri, any cause of action brought by a Claimant, Employee, Participant, former Employee, former Participant or any beneficiary of such an individual involving benefits under the Plan
shall be filed and conducted exclusively in the federal courts in the Eastern District of Missouri. 

  
 47 

 SECTION 17 - AMENDMENT AND TERMINATION 

 

	 	17.1.	Amendment. 

 The Company
shall have the right, by a resolution adopted by action of the Board or anyone to whom corporate authority to amend the Plan has been delegated by the Board, at any time and from time to time to amend, in whole or in part, any or all of the
provisions of the Plan. No such amendment, however, shall authorize or permit any part of the assets of the Plan (other than such part as is required to pay taxes and administration expenses of the Plan) to be used for or diverted to purposes other
than for the exclusive benefit of the Participants or their beneficiaries; no such amendment shall cause any reduction in the amount credited to any Participant’s account or cause or permit any portion of the assets of the Plan to revert to or
become the property of the Employer; provided, however, that if a favorable determination letter shall not be received upon the initial submission to the Internal Revenue Service that the Plan as herein set forth or as amended meets the requirements
of Sections 401(a), 401(k) and 501(a) of the Code, the Company may, at its option, amend the Plan in any manner which will result in a favorable determination letter being issued by the Internal Revenue Service or the Company may withdraw all
contributions made by it and the Plan shall then terminate with the same effect as if it had never been adopted. 
  

	 	17.2.	Termination; Discontinuance Of Contributions. 

 The Company shall have the right at any time to terminate this Plan. Upon termination, partial termination, or complete discontinuance of contributions, all Participants’ accounts (or, in the case of
a partial termination, the accounts of all affected Participants) shall become fully vested, and shall not thereafter be subject to forfeiture. 

  
 48 

 SECTION 18 - MISCELLANEOUS 

 

	 	18.1.	Participants’ Rights. 

 Neither the establishment of the Plan hereby created, nor any modification thereof, nor the creation of any fund or account, nor the payment of any benefits, shall be construed as giving to any
Participant or other person any legal or equitable right against the Employer, any officer or Employee thereof, the Trustee or the Board except as herein provided. Under no circumstances shall the terms of employment of any Participant be modified
or in any way affected hereby. 
  

	 	18.2.	Spendthrift Clause. 

Except as provided in Section 5.1, no benefit or beneficial interest provided under the Plan shall be subject in any manner to
anticipation, alienation, sale, transfer, assignment, pledge, encumbrance or charge, either voluntary or involuntary, and any attempt to so alienate, anticipate, sell, transfer, assign, pledge, encumber or charge the same shall be null and void. No
such benefit or beneficial interest shall be liable for or subject to the debts, contracts, liabilities, engagements, or torts of any person to whom such benefits or funds are or may be payable. 

Notwithstanding the above, a Participant’s benefit will be offset against any amount he or she is ordered or required to pay to the
Plan pursuant to an order or requirement which arises under a judgment of conviction for a crime involving the Plan, under a civil judgment entered by a court in an action involving a fiduciary breach, or pursuant to a settlement agreement between
the Participant and the Department of Labor or the Pension Benefit Guaranty Corporation. Any such offset shall be made pursuant to Section 206(d) of ERISA. 
  

	 	18.3.	Delegation Of Authority By Employer. 

 Whenever the Employer, under the terms of this Plan, is permitted or required to do or perform any act, it shall be done and performed by any Committee or officer duly authorized by the board of directors
of the Employer. If no such Committee or officer has been so authorized, such act shall be done and performed by resolution of the Board of Directors of the Company. 
  

	 	18.4.	Distributions To Minors. 

In the event that any portion of the Plan becomes distributable to a minor or other person under legal disability (as determined by the
laws of the jurisdiction in which he or she then resides), the Plan Administrator shall direct that such distribution be made to the legal representative of such minor or other person. 

 

	 	18.5.	Construction Of Plan. 

Except as provided in ERISA, this Plan shall be construed according to the laws of the State of Delaware, and all provisions of the Plan
shall be administered according to the laws of such state. 

  
 49 

	 	18.6.	Gender, Number And Headings. 

 Whenever any words are used herein in the masculine gender, they shall be construed as though they were also used in the feminine gender in all cases where they would so apply, and wherever any words are
used herein in the singular form, they shall be construed as though they were also used in the plural form in all cases where they would so apply. Headings of Sections and Subsections are inserted for convenience of reference, constitute no part of
the Plan and are not to be considered in the construction of the Plan. 
  

	 	18.7.	Separability Of Provisions. 

 If any provision of this Plan shall be for any reason invalid or unenforceable, the remaining provisions shall nevertheless be carried into effect. 

 

	 	18.8.	Diversion Of Assets. 

 No
part of the assets of the Plan shall be used for, or diverted to, purposes other than the exclusive benefit of Participants or their beneficiaries. Except as provided in Section 4.8, the Employer shall have no beneficial interest in the assets
of the Plan and no part of the assets of the Plan shall revert or be repaid to the Employer, directly or indirectly. 
  

	 	18.9.	Service Of Process. 

 The
Plan Administrator shall constitute the Plan’s agent for service of process. 
  

	 	18.10.	Merger. 

 In the event of
any merger or consolidation with, or transfer of assets or liabilities to, any other plan, each Participant shall (as if the Plan had then terminated) receive a benefit immediately after the merger, consolidation or transfer which is equal to or
greater than the benefit he or she would have been entitled to receive immediately before the merger, consolidation or transfer (if the Plan had then terminated). 
  

	 	18.11.	Benefit Limitation. 

 (a) Notwithstanding any other provision hereof, and except as provided in Section 13.1, the amounts allocated to a Participant during the Limitation Year under the Plan and allocated to the
Participant under any other defined contribution plan to which the Company or any other member of the Controlled Group has contributed shall be proportionately reduced, to the extent necessary, so that the Annual Addition does not exceed the lesser
of: 
 (1) $49,000, as adjusted for increases in the cost-of-living under Section 415(d) of the Code; or

 (2) 100% of the Participant’s compensation within the meaning of Section 415(c)(3) of the Code and
Treasury Regulations Section 1.415-2(d)(11)(i), including the deferrals described in Code Section 415(c)(3)(D), for the Limitation Year; provided that such compensation limit shall not include any contribution for

medical benefits after separation from service (within the meaning of Section 401(k) or 419A(f)(2) of the Code) which is otherwise treated as an Annual Addition. 

(b) For purposes of this Section, Limitation Year means the 12 month period commencing on January 1 and ending on
December 31. 
 (c) For purposes of Section 18.11(a)(2), compensation within the
meaning of Code Section 415(c)(3) means remuneration as defined in Treasury Regulation Section 1.415(c)-2(d)(4) (e.g., amounts reported in Box 1 of Form W-2, plus amounts that would have been received and includible in gross income but for

not include any severance pay, paid after an Employee’s termination of employment. In addition, such amount shall not include other compensation paid after an individual’s termination of employment; provided that, to the extent that the
following amounts are otherwise included in the definition of remuneration and are paid no later than the later of the date which is 2 1/2 months after termination of employment or the end of the Limitation Year that includes the date of termination of employment, such amounts paid after an
Employee’s termination of employment shall be deemed remuneration: 
 (1) regular pay, including
compensation for services during regular working hours, overtime, shift differential, commissions, bonuses or other similar payments; and 
 (2) payment for unused accrued sick, vacation or other leave, but only if the Employee would have been able to use the leave if employment had continued, and payment received pursuant to a nonqualified,
unfunded deferred compensation plan sponsored by the Employer, but only if the Employee would have received the payment at the same time if employment had continued and only to the extent the payment is includible in the Employee’s gross
income. 
 The exclusions provided for in this Section 18.11(c) with respect to post-employment payments shall not apply to
payments to an individual who does not currently perform services for the Employer by reason of: 
 (3)
qualified military service under Code Section 414(u)(1), to the extent such payments do not exceed the compensation such individual would have received from the Employer if he or she had continued to perform services for the Employer, including
differential wage payments as defined in Section 3401(h)(2) of the Code; or 
 (4) permanent and total
disability under Code Section 22(e)(3), provided either that: 
 (A) the individual was not a Highly
Compensated Employee immediately before becoming disabled, or 

  
 51 

 (B) the individual was a Highly Compensated Employee immediately before
becoming disabled, and the Employer provides continuation of compensation for a fixed or determinable period after termination of employment on behalf of all Participants who are totally and permanently disabled within the meaning of this
Section 18.11(c)(4). 
 (d) For purposes of this Section, Annual Additions means the sum for the Limitation
Year of Employer contributions, Employee contributions (determined without regard to any rollover contributions as defined in Sections 402(c), 403(a)(4), 403(b)(8), 408(d)(3) and 457(e)(16) of the Code and without regard to Employee contributions to
a simplified employee pension plan which are excludable from gross income under Section 408(k)(6) of the Code) and reallocated forfeitures. 
  

	 	18.12.	Commencement Of Benefits. 

 (a) Except as otherwise provided in Section 9.1, 10.1.3 or 11.1.3, the payment of benefits under the Plan to the Participant will begin not later than the 60th day after the close of the Plan Year in
which the last of the following occurs: 
 (1) the date on which the Participant attains age 62 (or, in the case
of a Participant who was a participant in the Dodge Hill Mining Company, LLC 401(k) Plan on December 31, 2005, age 60); or 
 (2) the 10th anniversary of the date on which the Participant commenced participation in the Plan; or 
 (3) the Participant’s termination of employment with the Employer. 
 Notwithstanding the foregoing, if a Participant’s aggregate account balance exceeds $5,000 (excluding rollover contributions and earnings thereon), in no case shall distribution commence until the
later of the date on which the Participant attains age 62 or his or her Normal Retirement Age unless the Participant elects an earlier distribution in the manner provided in Section 10.3 or 11.4. 

(b) Notwithstanding Subsection (a) or any other provision of the Plan, if the amount of payment cannot be
ascertained, or if it is not possible to make payment because the Plan Administrator cannot locate the Participant after making reasonable efforts to do so, a retroactive payment may be made no later than 60 days after the earliest date on which the
amount of such payment can be ascertained or the date on which the Participant is located, whichever is applicable. 
 (c) If the Plan Administrator is unable to locate any person entitled to receive distribution from an account hereunder, such account shall be forfeited and used to reduce Employer contributions on the
date two years after: 
 (1) the date the Plan Administrator sends by certified mail a notice concerning the
benefits to such person at his or her last known address, or 

  
 52 

 (2) the Plan Administrator determines that there is no last known address.

 If an account is forfeited under this Section and a person otherwise entitled to the account subsequently
files a claim with the Plan Administrator during any Plan Year, before any allocations for such Plan Year are made the account will be restored to the amount which was forfeited without regard to any earnings or losses that would have been
allocated. Such restoration shall first be taken out of forfeitures which have not been allocated and if such forfeitures are insufficient to restore such person’s account balance, restoration shall be made by an Employer contribution to the
Plan. 
  

	 	18.13.	Qualified Domestic Relations Order. 

 Notwithstanding anything in the Plan to the contrary, benefits may be distributed in accordance with the terms of a Qualified Domestic Relations Order (“QDRO”). For this purpose a QDRO is any
Domestic Relations Order determined by the Employer to be a Qualified Domestic Relations Order within the meaning of Section 414(p) of the Code pursuant to this Section. 

(a) A Domestic Relations Order means a judgment, decree, or order (including the approval of a property settlement
agreement) which 
 (1) relates to the provision of child support, alimony payments, or marital property rights
to a Spouse, former Spouse, child or other dependent of a Participant, 
 (2) is made pursuant to a state
domestic relations law, and 
 (3) creates or recognizes the existence of an Alternate Payee’s right, or
assigns to the Alternate Payee the right, to receive all or a portion of the benefits of the Participant under the Plan. 
 An “Alternate Payee” includes any Spouse, former Spouse, child, or other dependent of a Participant who is designated by the Domestic Relations Order as having a right to receive all or a
portion of the benefits payable under the Plan with respect to the concerned Participant. 
 (b) To be a QDRO,
the Domestic Relations Order must meet the specifications set forth in Section 414(p) of the Code and must clearly specify the following: 
 (1) Name and last known mailing address of the Participant. 
 (2)
Name and last known mailing address of each Alternate Payee covered by the Domestic Relations Order. 
 (3) The
amount or the percentage of the Participant’s benefit to be paid to each Alternate Payee, or the manner in which such amount or percentage is to be determined. 

  
 53 

 (4) The number of payments or period to which the Domestic Relations Order
applies. 
 (5) Each plan to which the Domestic Relations Order applies. 

(c) The status of any Domestic Relations Order as a QDRO shall be determined under the following procedures: 

(1) Upon receiving notice that a potential Alternate Payee intends to obtain a QDRO with respect to a Participant’s
benefits under the Plan (such as notice that the potential Alternate Payee is currently seeking a Domestic Relations Order), the Employer may, in its discretion, delay any payments of such Participant’s benefits for a reasonable period of time.

 (2) Promptly upon receiving a Domestic Relations Order, the Employer will notify the affected Participant and
any Alternate Payee of the receipt by the Plan of the Domestic Relations Order and of the Plan’s procedures for determining its qualified status. 
 (3) Within a reasonable period after receipt of a Domestic Relations Order, the Employer will review the Domestic Relations Order to determine whether the order is a QDRO. After determining whether a
Domestic Relations Order is a QDRO, the affected Participant and each Alternate Payee (or any representative designated by an Alternate Payee by written notice to the Employer) shall be furnished a copy of such determination. The notice shall state:

 (A) whether the Domestic Relations Order has been determined to be a QDRO; and 

(B) if the Domestic Relations Order is determined to be a QDRO, that the Employer will commence any payments currently
due under the Plan or the QDRO to the person or persons entitled thereto after the expiration of a period of 60 days commencing on the date of the mailing of the notice unless prior thereto the Employer receives notice of legal proceedings disputing
the determination. The Employer shall, as soon as practical after such 60 day period, ascertain the dollar amount currently payable to each payee pursuant to the Plan and the QDRO, and any such amounts shall be disbursed by the Plan. 

(4) If there is a dispute on the status of a Domestic Relations Order as a QDRO, there shall be a delay in making
payments. The Employer shall direct that the amounts otherwise payable be separately accounted for within the Plan. If within 18 months after the date the first payment would be required to be made under the Domestic Relations Order, the Domestic
Relations Order is determined not to be a valid QDRO, or the status of the Domestic Relations Order has not been finally determined, such amounts (including interest thereon) shall be paid to the person or persons who would have been entitled to
such amounts if there had been no Domestic Relations Order. Any determination thereafter that the Domestic Relations Order is a QDRO shall be applied prospectively only. 

  
 54 

 (d) If a Domestic Relations Order requires payment to an Alternate Payee in
an immediate lump sum, the order shall not lose its status as a Qualified Domestic Relations Order merely because of the immediate lump sum provision. 
  

	 	18.14.	Written Explanation Of Rollover Treatment. 

 The Employer shall, when making an eligible rollover distribution, provide an explanation (or summary thereof) to the recipient of such distribution of his or her right to roll over such distribution to
an eligible retirement plan and, if applicable, his or her right to the special five or ten-year averaging and capital gains tax treatment in the Code. Such explanation (or summary) will be provided to the recipient in accordance with rules
prescribed by the Internal Revenue Service. 
  

	 	18.15.	Leased Employees. 

 Any
person who is a leased employee of any member of the Controlled Group shall be treated for all purposes of the Plan as if he or she were employed by a member of the Controlled Group which has not adopted the Plan. In the case of a Leased Employee or
an Employee, Years of Service shall be determined by taking into account any period for which the individual would have been a Leased Employee but for the fact that he or she had not performed services for a member of the Controlled Group on a
substantially full-time basis for a period of at least one year. A transfer from the status of an employee of the Employer to that of a Leased Employee shall not be considered a termination of employment under the Plan. An individual who has such a
transfer shall not have a termination of employment until he or she ceases to be an employee of the Employer and all members of its Controlled Group and is no longer a Leased Employee. 

 

	 	18.16.	Special Distribution Option. 

 Notwithstanding any provision of the Plan to the contrary that would otherwise limit a Distributee’s (as hereinafter defined) election under this Section, a Distributee may elect, at the time and in
the manner prescribed by the Plan Administrator, to have any portion of an Eligible Rollover Distribution (as hereinafter defined) paid directly to an Eligible Retirement Plan (as hereinafter defined) specified by the Distributee in a Direct
Rollover. 
 (a) 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: 
 (1) any
distribution that is one of a series of substantially equal periodic payments (not less frequently than annually) made for the life (or life expectancy) of the Distributee or the joint lives (or joint life expectancies) of the Distributee and the
Distributee’s designated beneficiary, or for a specified period of ten years or more; 

  
 55 

 (2) any distribution to the extent such distribution is required under
Section 401(a)(9) of the Code; or 
 (3) any hardship distribution. 

(b) An Eligible Retirement Plan is 

(1) an individual retirement account described in Section 408(a) of the Code, 

(2) an individual retirement annuity described in Section 408(b) of the Code, 

(3) an annuity plan described in Section 403(a) of the Code, or 

(4) a qualified trust described in Section 401(a) of the Code, 

(5) an eligible deferred compensation plan described in Section 457(b) of the Code which is maintained by an
eligible employer described in Section 457(e)(1)(A) of the Code, or 
 (6) an annuity contract described in
Section 403(b) of the Code, or 
 (7) to the extent permitted by applicable law, a Roth IRA described in
Code Section 408A, 
 that accepts the Distributee’s Eligible Rollover Distribution. However, in the case of an
Eligible Rollover Distribution to a Distributee who is a nonspouse beneficiary, an Eligible Retirement Plan is only an individual retirement account or individual retirement annuity. 

(c) A Distributee includes an Employee or former Employee. In addition, the Employee’s or former Employee’s
surviving Spouse, the Employee’s or former Employee’s Spouse or former Spouse who is the Alternate Payee under a Qualified Domestic Relations Order, as defined in Section 414(p) of the Code, and the Employee’s or former
Employee’s nonspouse beneficiary who is an individual (or, to the extent permitted in regulations issued under Section 402(c)(11)(B) of the Code, a trust) designated in accordance with Section 12.3 are Distributees with regard to the
interest of the surviving Spouse, Spouse, former Spouse or nonspouse beneficiary. 
 (d) A Direct Rollover
payment is a payment by the Plan to the Eligible Retirement Plan specified by the Distributee. 
 (e) The
Employer shall provide notice of the special distribution option described in the preceding Section to the Participant in accordance with rules prescribed by the Internal Revenue Service. 

  
 56 

	 	18.17.	Waiver Of 30-Day Period. 

A Participant who receives the notice (or summary) described in Section 10.3.1 or 11.3.1 will simultaneously receive the notice (or
summary) described in Section 18.14 and will be given the opportunity to consider for at least 30 days after such notices (or summaries) are provided the decision of whether or not to elect a Direct Rollover (as described in Section 18.16)
and whether or not to elect to defer receipt of his or her vested benefit. A Participant may waive such opportunity to consider such elections for at least 30 days by making an election before the 30 day time period has elapsed. Notwithstanding any
provision herein to the contrary, the Employer may distribute a Participant’s vested benefit pursuant to his or her distribution election forms at any time following such Participant’s waiver of the opportunity to consider such elections
for at least 30 days. 
  

	 	18.18.	Construction Of Plan. 

Except as provided in ERISA, this Plan shall be construed according to the laws of the State of Missouri, and all provisions of the Plan
shall be administered according to the laws of such state. 
  

	 	18.19.	General Fiduciary Standard of Conduct. 

 Each fiduciary of the Plan shall discharge his duties hereunder solely in the interest of the Participants and their beneficiaries and for the exclusive purpose of providing benefits to Participants and
their beneficiaries and defraying reasonable expenses of administering the Plan. Each fiduciary shall act with the care, skill, prudence and diligence under the circumstances that a prudent man acting in a like capacity and familiar with such
matters would use in conducting an enterprise of like character and with like aims, in accordance with the documents and instruments governing this Plan. 
  

	 	18.20.	Effect of a Mistake. 

 In
the event of a mistake or misstatement as to the eligibility or participation or compensation of any Participant, or the amount of contributions allocated to or made on behalf of a Participant, or payments made or to be made to a Participant or
beneficiary, the Plan Administrator shall, if possible, cause to be withheld or accelerated or otherwise make adjustment of such amounts or payments as will in its sole judgment entitle the Participant or beneficiary to the proper amount of payment
under the Plan. Correction of a mistake described herein may include the Employer making a qualified nonelective contribution (QNEC) to the Plan or any other acceptable and reasonable method of correction permitted under a retirement plan correction
program such as the Employee Plans Compliance Resolution System. 

  
 57 

 SECTION 19 - TOP-HEAVY DEFINITIONS 

 

	 	19.1.	Accrued Benefits. 

“Accrued Benefits” means “the present value of accrued benefits” as that phrase is defined under regulations issued
under Section 416 of the Code. For purposes of Sections 19 and 20 hereof, the Accrued Benefits of any Participant (other than a Key Employee) shall be determined under the single accrual rate used by all Qualified Plans of the Employer which
are defined benefit plans, or if there is no single accrual rate, Accrued Benefits shall be determined as accruing no more rapidly than the slowest rate permitted under Section 411(b)(1)(C) of the Code. The present values of Accrued Benefits
and the amounts in accounts of an employee as of the Determination Date shall be increased by the distributions made with respect to the employee under the Plan and any plan aggregated with the Plan under Section 416(g)(2) of the Code during
the one year period ending on the Determination Date. The preceding sentence shall also apply to distributions under a terminated plan which, had it not been terminated, would have been aggregated with the Plan under Section 416(g)(2)(A)(i) of
the Code. In the case of a distribution made for a reason other than separation from service, death or disability, this provision shall be applied by substituting “five year period” for “one year period.” 

 

	 	19.2.	Beneficiaries. 

“Beneficiaries” means the person or persons to whom the share of a deceased Participant’s accounts are payable.

  

	 	19.3.	Determination Date. 

“Determination Date” means for a Plan Year the last day of the preceding Plan Year. 

 

	 	19.4.	Former Key Employee. 

“Former Key Employee” means any person presently or formerly employed by the Controlled Group (and the Beneficiaries of such
person) who during the Plan Year is not classified as a Key Employee but who was classified as a Key Employee in a previous Plan Year; provided, however, that a person who has not performed any services for the Controlled Group at any time during
the one year period ending on the Determination Date (and the Beneficiaries of any such person) shall not be considered a Former Key Employee. 
  

	 	19.5.	Key Employee. 

 “Key
Employee” means any person presently or formerly employed by the Controlled Group (and the Beneficiaries of such person) who is a “key employee” as that term is defined in Section 416(i) of the Code and the regulations
thereunder; provided, however, that a person who has not performed any services for the Controlled Group at any time during the one year period ending on the Determination Date (and the Beneficiaries of any such person) shall not be considered a Key
Employee. For purposes of determining whether a person is a Key Employee, the definition of Top Heavy Compensation shall be applied. 

  
 58 

	 	19.6.	Non-Key Employee. 

“Non-Key Employee” means any person presently or formerly employed by the Controlled Group (and the Beneficiaries of such
person) who is not a Key Employee or a Former Key Employee; provided, however, that a person who has not performed any services for the Controlled Group at any time during the one year period ending on the Determination Date (and the Beneficiaries
of any such person) shall not be considered a Non-Key Employee. 
  

	 	19.7.	Permissive Aggregation Group. 

 “Permissive Aggregation Group” means each Qualified Plan of the Controlled Group in the Required Aggregation Group plus each other Qualified Plan which is not part of the Required Aggregation
Group but which satisfies the requirements of Sections 401(a)(4) and 410 of the Code when considered together with the Required Aggregation Group. 
  

	 	19.8.	Required Aggregation Group. 

 “Required Aggregation Group” means each Qualified Plan (including any terminated Qualified Plan) of the Controlled Group in which a Key Employee participates during the Plan Year containing the
Determination Date or any of the four preceding Plan Years and each other Qualified Plan (including any terminated Qualified Plan) of the Controlled Group which during this period enables any Qualified Plan (including any terminated Qualified Plan)
in which a Key Employee participates to meet the requirements of Section 401(a)(4) or 410 of the Code. 
  

	 	19.9.	Top-Heavy Compensation. 

“Top-Heavy Compensation” means compensation within the meaning of Section 415(c)(3) of the Code. For purposes of this
Section 19.9, compensation within the meaning of Section 415(c)(3) shall mean remuneration as defined in Section 18.11(c). 
  

	 	19.10.	Top-Heavy Group. 

“Top-Heavy Group” means, for a Plan Year, the Required Aggregation Group if, and only if, the sum of the Accrued Benefits
(valued as of the Determination Date for such Plan Year) under all Qualified Plans (including any terminated Qualified Plans) in the Required Aggregation Group for Key Employees exceeds 60% of the sum of the Accrued Benefits (valued as of such
Determination Date) under all Qualified Plans (including any terminated Qualified Plans) in the Required Aggregation Group for all Key Employees and Non-Key Employees; provided, however, that the Required Aggregation Group will not be a Top-Heavy
Group for a Plan Year if the sum of the Accrued Benefits (valued as of the Determination Date for such Plan Year) under all Qualified Plans (including any terminated Qualified Plans) in the Required Aggregation Group for Key Employees does not
exceed 60% of the sum of the Accrued Benefits (valued as of such Determination Date) under all Qualified Plans in the Permissive Aggregation Group for all Key Employees and Non-Key Employees. If the Qualified Plans in the Required or Permissive
Aggregation Group have different Determination Dates, the Accrued Benefits under each such Plan shall be calculated separately, and the Accrued Benefits as of Determination Dates for such Plans that fall within the same calendar year shall be
aggregated. 

  
 59 

 SECTION 20 - TOP-HEAVY RULES 

 

	 	20.1.	Special Top-Heavy Rules. 

If for any Plan Year the Plan is part of a Top-Heavy Group, then, effective as of the first day of such Plan Year the following new
Section 7.3 is added to apply to Participants who accrue an Hour of Employment on or after the first day of such Plan Year: 
  

	 	7.3	Minimum Allocation if Plan is part of Top-Heavy Group. 

 Notwithstanding the foregoing, for each Plan Year in which the Plan is part of a Top-Heavy Group, the sum of the Employer contributions and forfeitures allocated under the Plan to the account of each
Non-Key Employee who is both a Participant and Employee on the last day of such Plan Year shall be at least equal to the lesser of three percent of such Non-Key Employee’s Top-Heavy Compensation for such Plan Year or the largest percentage of
Top-Heavy Compensation allocated to the account of any Key Employee; provided, however, that if for any Plan Year a Non-Key Employee is a Participant in both this Plan and one or more defined contribution plans, the Employer need not provide the
minimum allocation described in the preceding sentence for such Non-Key Employee if the Employer satisfies the minimum allocation requirement of Section 416(c)(2)(B) of the Code for the Non-Key Employee in such other defined contribution plans.
Amounts which a Non-Key Employee or Key Employee elects to contribute on a pre-tax basis to a Qualified Plan which meets the requirements of Section 401(k) of the Code shall be considered an Employer contribution for purposes of
Section 19.10; provided, however, that such pre-tax contributions made by Non-Key Employees may not be taken into account in determining the minimum allocation provided under this Section. In addition, matching contributions made on behalf of
Non-Key Employees may be taken into account in determining the minimum allocation provided under this Section. 
 IN WITNESS WHEREOF, the Company has caused this amendment and Plan restatement to be executed by one of its duly authorized officers this 18th day of November, 2010.
