	Article 1.	The Plan 

  

	1.1	Plan History and Merger 

 The plan is known as the “PCS U.S. Employees’ Savings Plan for
Collectively Bargained Employees.” It is a successor by merger as described in this Section. 
 Effective as of 11:59:59 p.m. on December 31, 2011
(the “Merger Date”), the PCS Nitrogen 401(k) Savings Plan (the “Prior Nitrogen Plan”) was merged with and into the White Springs Agricultural Chemicals, Inc. Savings and Investment Plan for Collective Bargaining Employees (the
“Prior White Springs Plan”), and the newly merged plan was renamed the PCS U.S. Employees’ Savings Plan for Collectively Bargained Employees. The history for the Prior Nitrogen Plan and the Prior White Springs Plan is set forth in
Appendix A. 
 The assets and liabilities of the Prior Nitrogen Plan were transferred to the Plan’s Trust as soon as administratively practicable on or
around the Merger Date. The merger of the Prior Nitrogen Plan with and into this Plan and the transfer of assets was made in accordance with the Code and the Treasury Regulations thereunder, as applicable. Any Participant who had an Account under
the Prior Nitrogen Plan on the Merger Date, or of any persons who were claiming benefits through such Participant, had an Account balance under this Plan immediately after the Merger Date equal to the Account balance he or she would have been
entitled to receive under the Prior Nitrogen Plan or the Prior White Springs Plan immediately before the Merger Date. 
 The Plan was most recently amended
and restated, effective as of January 1, 2012, to reflect changes in laws and regulations issued since the time of the last Plan restatement, and to incorporate Plan amendments adopted since the last restatement. 

Effective as of January 1, 2017, the Plan is hereby further amended and restated to incorporate Plan amendments adopted since the last restatement, and
to reflect certain design changes and administrative clarifications. 
  

	1.2	Applicability of the Plan 

 The provisions set forth herein are applicable only to Employees in the
employ of an Employer on or after January 1, 2017, and other former Employees who have an Account balance. Except as otherwise provided herein, the terms of this Plan document shall not affect the rights and benefits of any person who, as of
January 1, 2017, had terminated employment with all Employers. The applicable terms of the Prior Plan shall govern the rights and benefits of those persons. 

The Plan provisions, together with any Appendices and Supplements, shall apply to all Eligible Employees. However, to the extent that there is any conflict or
ambiguity between the terms of the Plan and an Appendix or Supplement, the terms of the Appendix or Supplement shall govern as to those Eligible Employees covered by such Appendix or Supplement. 








	1.3	Purpose 

 The Plan is maintained for the exclusive benefit of Eligible Employees and their Beneficiaries.
The purpose of the Plan is to (i) provide retirement and other benefits for Eligible Employees, (ii) enable Eligible Employees, through systematic savings, to accumulate funds on a tax advantageous basis; and (iii) provide a vehicle
through which an Employer can attract and retain qualified Employees. 
  

	1.4	Intent 

 The Plan is intended to constitute (i) a qualified profit sharing plan, as described in
Section 401(a) of the Internal Revenue Code of 1986, as amended (the “Code”), which includes a qualified cash or deferred arrangement under Code Section 401(k), (ii) an Employee Stock Ownership Plan within the meaning of
Code Section 4975(e)(7) (“ESOP”), (iii) a 404(c) plan (within the meaning of Section 404(c) of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), and (iv) an “eligible individual
account plan” within the meaning of ERISA Section 407(d). 

  
 2 









	Article 2.	Definitions and Construction 

  

	2.1	Definitions

below unless otherwise expressly provided. 
  

	(a)	“A&W Plan Participant” means an individual who was a “participant” in the Albright & Wilson Americas Inc. 401(k) Savings Plan (the “A&W Plan”) maintained by
Albright & Wilson Americas Inc. immediately before the “closing date” (as defined in that plan), and who became a participant in the Prior Nitrogen Plan as of the “closing date.” 


 

	(b)	“Account” or “Accounts” means the Account or Accounts maintained for each Participant which represents his total proportionate interest in the Trust and which consists of the following:


  

	 	(1)	“After-Tax Contributions Account” means the account maintained for each Participant to hold the Participant’s After-Tax Contributions and Adjustment Contributions. 


 

	 	(2)	“Before-Tax Contributions Account” means the account maintained for each Participant to hold the Participant’s Before-Tax Contributions. 


 

	 	(3)	“Catch-Up Contributions Account” means the account maintained for each Participant to hold the Participant’s Catch-Up Contributions described in Section 4.1(d). 


 

	 	(4)	“Employer Matching Contributions Account” means the account maintained for each Participant to hold the Participant’s Employer Matching Contributions. 


 

	 	(5)	“Employer Performance Contributions Account” means the account maintained for each Participant to hold the Participant’s Employer Performance Contributions. 


 

	 	(6)	“Rollover Account” means the account maintained for each Employee to hold amounts rolled over or transferred from other qualified plans and accounts. 


 

	 	(7)	Any such other account as the Committee may designate. 

 Each Account reflects its allocable
share of investment earnings, gains, and losses (realized and unrealized) pursuant to Section 7.1 and Plan expenses chargeable under Section 15.4. 
  

	(c)	“Adjustment Contributions” means Before-Tax Contributions which were converted to After-Tax Contributions before January 1, 2015 in order to comply with the applicable nondiscrimination tests of
Code Section 401(k). 


  
 3 









	(d)	“Affiliate” means: 

  

	 	(1)	any company which is a member of a controlled group of corporations (within the meaning of Code Section 414(b)) which also includes as a member the Company, 


 

	 	(2)	any trade or business (whether or not incorporated) that is under common control (within the meaning of Code Section 414(c)) with the Company, 


 

	 	(3)	any organization (whether or not incorporated) which is a member of an affiliated service group (as defined in Code Section 414(m)) which includes the Company, and 


 

	 	(4)	any other entity required to be aggregated with the Company pursuant to the Treasury Regulations under Code Section 414(o). 


Notwithstanding the foregoing, for purposes of Section 4.10, the definitions in Code Sections 414(b) and (c) shall be modified by
substituting the phrase “more than fifty percent (50%)” for the phrase “at least 80 percent (80%)) each place it appears in Code Section 1563(a)(1). 
  

	(e)	“After-Tax Contributions” means After-Tax Contributions described in Section 4.2. 

  

	(f)	“Before-Tax Contributions” means Before-Tax Contributions described in Sections 4.1(a) and (b). 

  

	(g)	“Beneficiary” or “Beneficiaries” means the person, persons (who may be named contingently or successively), or entity designated by a Participant to receive a Plan benefit in the
event of the Participant’s death. Each Beneficiary designation will revoke all prior designations made by the Participant. A Beneficiary designation shall be made in the time and manner prescribed by the Committee, and will be effective as soon
as administratively practicable after such designation is filed with the Committee. Notwithstanding the foregoing, in the case of a married Participant, the Participant’s Spouse will automatically be the Beneficiary unless (i) the
Participant has designated another person as his Beneficiary; (ii) the Participant’s Spouse has consented in writing to the designation of the specific non-Spouse Beneficiary, including any class of Beneficiaries or any contingent
Beneficiaries; (iii) the Participant’s Spouse acknowledges the effect of such election; and (iv) the Spouse’s consent is witnessed by a notary public. 


Notwithstanding the foregoing, the Spouse’s consent is not required if the Spouse cannot be located or if the Participant furnishes the
Committee a court order decreeing that the Participant and the Spouse are legally separated or that the Spouse has abandoned the Participant. In addition, if a Participant’s Spouse is designated as the Participant’s Beneficiary and the
Participant and Spouse divorce, the designation will be automatically revoked, and the former Spouse will have no further rights as a Beneficiary (except as otherwise provided by a qualified domestic relations order under Code Section 414(p)),
unless the Participant completes a new Beneficiary designation identifying the former Spouse as the Beneficiary. If no Beneficiary designation is in effect at the time of the Participant’s death, or if no designated Beneficiary survives the
Participant, payment of the Participant’s Account will be made in the following order: 

  
 4 









	 	(1)	to the Participant’s living Spouse; 

  

	 	(2)	if the Participant has no living Spouse, then to his living children (in equal shares); 

  

	 	(3)	if the Participant has no living children, then to his living parents (in equal shares); 

  

	 	(4)	if the Participant has no living parents, then to his living brothers and sisters (in equal shares); or 

  

	 	(5)	if the Participant has no living brothers or sisters, then to his estate. 

 The Committee will,
in its sole and absolute discretion, determine the right of such persons to receive the Participant’s Plan Account, if any. If the Committee is in doubt as to the right of any person to receive such amount, the Committee may direct the Trustee
to retain such amount, without liability for any interest on such amount, until the rights to such amount are determined, or, alternatively, may direct the Trustee to pay such amount into any court of appropriate jurisdiction and such payment will
be a complete discharge of the liability of the Plan and the Trust. 
 Any Beneficiary designation made by a Participant who participated in
the A&W Plan before the “closing date” (as defined in that plan) shall continue in effect as though such beneficiary designation had been made under the Plan, unless and until a new Beneficiary designation is made by such Participant.

  

	 	(h)	“Board of Directors” means the Board of Directors of the Company. 

  

	 	(i)	“Code” means the Internal Revenue Code of 1986, as it may be amended interpreted and applied by regulations and rulings issued pursuant thereto, all as amended from time to time. 


 

	 	(j)	“Committee” means the committee described in Article 12. 

  

	 	(k)	“Company” means PCS Administration (USA), Inc. 

  

	 	(l)	“Compensation” means the following:

services performed), paid during a Plan Year by the Employer for services while an active Participant during that Plan Year. 


  
 5 









	 	(A)	In addition, Compensation also includes: 

  

	 	(i)	any elective deferrals, as defined in Code Section 401(g)(3), contributed to any plan maintained by the Employer, and any amount that is contributed or deferred by the Employer at the election of the Participant
and which is not includible in the gross income of the Participant by reason of Code Sections 125 or 132(f)(4)); and 

  

	 	(ii)	any differential wage payments paid to a Participant by the Employer while performing qualified military service (as defined in Code Section 414(u)(5)) for a period of more than 30 days and represents all or a
portion of the wages the Participant would have received if the Participant were performing services for the Employer, as provided under the Heroes Earnings Assistance and Relief Tax Act of 2008. 


For purposes of applying the discrimination tests of Section 4.8, amounts described in Section 2.1(l)(1)(A)(i) above, may be
excluded at the election of the Committee pursuant to applicable law and regulations. 
  

	 	(B)	Notwithstanding the foregoing, Compensation does not include: 

  

	 	(i)	reimbursements or other expense allowances; 

  

	 	(ii)	fringe benefits (cash and/or noncash); 

  

	 	(iii)	moving expenses; 

  

	 	(iv)	deferred compensation; 

  

	 	(v)	severance benefits; and 

  

	 	(vi)	other welfare benefits, even if any of the foregoing items are includible in gross income. 


Notwithstanding the foregoing, this subsection (B) shall not apply for purposes of determining Compensation under Section 4.10
(relating to the limitation on annual additions). 
  

	(2)	Compensation for Purposes of Determining Contributions. For purposes of Sections 4.1, 4.2, 4.3 and 4.4 (relating to Before-Tax Contributions, After-Tax Contributions, Employer Matching Contributions and Employer
Performance Contributions), Compensation shall have the meaning set forth in Appendix C (for Employees of PCS Nitrogen Ohio, L.P. or PCS Purified Phosphates) and Appendix D (for Employees of White Springs Agricultural Chemicals, Inc.).



  
 6 









	(3)	Compensation For Purposes of Annual Additions. For purposes of Section 4.10 (relating to the limitation on annual additions), Compensation shall also include: 


 

	 	(A)	Payments made after severance from employment of base salary, overtime pay, shift differential, commissions, bonuses and similar types of payments shall be included in Compensation, provided that such payments are made
within 2-1/2 months after severance from employment (or by the end of the Plan Year in which the severance from employment occurred, if later) and such payments would have been paid to the Participant before severance from employment if the
Participant had continued in employment. 

  

	 	(B)	Payment for unused accrued sick, vacation, or other leave that would have been included as Compensation if paid before the termination, which is paid within the later of (i) 2-1/2 months after severance from
employment, or (ii) by the end of the Plan Year in which the severance from employment occurred if such payments would have been paid to the Participant before severance from employment if the Participant had continued in employment with an
Employer. 

  

	 	(C)	Salary continuation payments made to a Participant who leaves employment to perform qualified military service (as defined in Code Section 414(u)(5)), to the extent that those payments do not exceed the amounts the
Participant would have otherwise received, if the Participant had otherwise continued to provide services for an Employer. 

  

	 	(D)	Short-term disability payments. 

 Notwithstanding anything to the contrary, severance pay and
parachute payments under Code Section 280G(b)(2) paid to a Participant after his Vesting Service terminates shall not be included as Compensation. 
  

	(4)	Dollar Limitation on Compensation. Notwithstanding any other provision of the Plan (including an Appendix or Supplement) to the contrary, the Compensation of each Participant taken into account under the Plan
will not exceed the limit under Code Section 401(a)(17), as adjusted for cost-of-living increases in accordance with Code Section 401(a)(17)(B) ($270,000 effective for the calendar year beginning January 1, 2017). If the Plan Year or
such other period consists of fewer than 12 months, the annual Compensation limit will be multiplied by a fraction, the numerator of which is the number of months in such period and the denominator of which is 12. 


 

	(5)	Alternative Method. The Committee may elect an alternative method of determining Compensation pursuant to regulations issued by the Internal Revenue Service. 


  
 7 









	 	(m)	“Direct Rollover” means an Eligible Rollover Distribution that is paid by the Plan for the benefit of a Distributee to an Eligible Retirement Plan specified by the Distributee in accordance with Section
8.12. 

  

	 	(n)	“Disability” or “Disabled” means a total disability within the meaning of the Employer’s long-term disability program. 


 

	 	(o)	“Distributee” means a Participant, former Participant, Beneficiary (if the surviving Spouse of the Participant, or, if not the surviving Spouse of the Participant, such non-Spouse Beneficiary, but only
with respect to a distribution that is paid by the Plan for the benefit of a non-Spouse Beneficiary: (a) to an individual retirement account described in Code Section 408(a) or (b) to an individual retirement annuity described in Code
Section 408(b) that is treated as an inherited account under Code Section 402(c)(11)) or an alternate payee under a qualified domestic relations order who receives a distribution from an Eligible Retirement Plan. 


 

	 	(p)	“Eligibility Computation Period” means (i) the one (1) year period commencing on the date the Employee is credited with his first Hour of Service with an Employer or an Affiliate,
(ii) the first Plan Year that begins after such date, and (iii) subsequent Plan Years. 

  

	 	(q)	“Eligibility Service” means an Eligibility Computation Period in which an Employee is credited with 1,000 Hours of Service. An Employee’s Eligibility Service will be disregarded if he incurs a
One-Year Break in Service (or such longer period as may be specified in the collective bargaining agreement to which the Employee is subject). Notwithstanding the foregoing, if an Employee who has incurred a One-Year Break in Service returns to
employment with an Employer or an Affiliate, the Employee will be credited with his prior Eligibility Service effective as of the first Hour of Service following reemployment unless: 


 

	 	(1)	at the time the Employee terminated employment the Employee (i) has not had any Before-Tax Contributions or Employer Performance Contributions made on his behalf, and (ii) does not have a vested interest in
any portion of his Employer Matching Contributions Account or Employer Performance Contributions Account, and

accordance with procedures established by the Committee, and shall be credited to the Participant’s Before-Tax Contributions Account as soon as practicable after such contributions are received by the Trustee. 


 

	(b)	Automatic Enrollment. Each Eligible Employee who becomes a Participant pursuant to Section 3.2(a) shall be automatically enrolled in Before-Tax Contributions. Such automatic enrollment shall provide for a

period of time after receipt of the notice described in subsection (c) to make an affirmative election to contribute or to affirmatively elect not to contribute to the Plan. 


 

	(c)	Automatic Enrollment Notice. Within a reasonable period of time (as determined by the Committee) before an Eligible Employee is automatically enrolled in the Plan, and annually thereafter, such Eligible Employee

Code and by the Secretary of the Treasury for cost-of-living increases). Notwithstanding the foregoing, such Catch-Up Contributions, when combined with a Participant’s Before-Tax Contributions under paragraph (a) above, may not exceed

first payroll period, or as soon as administratively practicable thereafter, after the election is received by the Committee, and will remain in effect for so long as the Participant is eligible to make Before-Tax Contributions or, if earlier, the
date the Participant modifies his Catch-Up Contribution election. Catch-Up Contributions will be credited to the Participant’s Catch-Up Contributions Account. Such Catch-Up Contributions will not be taken into account for purposes of the
provisions of the Plan implementing the required limitations of Code Sections 402(g) and 415. In addition, the Plan will not be treated as failing to satisfy the provisions of the Plan implementing the requirements of Code Sections 401(k)(3), 410(b)
and 416, as applicable, by reason of such Catch-Up Contributions being made. Catch-Up Contributions will be subject to the same in-service withdrawal rules that apply to Before-Tax Contributions under Sections 9.1(b) and 9.2(b). Notwithstanding
anything in the Plan to the contrary, the Employer will not make any Employer Matching Contributions under Section 4.3 with respect to a Participant’s Catch-Up Contributions.

payroll period, on behalf of each Participant who elects to make Before-Tax Contributions or After-Tax Contributions, an Employer Matching Contribution. Such Employer Matching Contribution shall be equal to one-hundred percent (100%) of such
Participant’s Before-Tax Contributions (not including Catch-Up Contributions) or After-Tax Contributions, up to a maximum of three percent (3%) of such Participant’s Compensation for the payroll period. 

Employer Matching Contributions shall first be made on the Participant’s Before-Tax Contributions. To the extent the Participant does not
elect to defer three percent (3%) of Compensation as Before-Tax Contributions, Employer Matching Contributions will next be made on the Participant’s After-Tax Contributions. Employer Matching Contributions shall be delivered to the
Trustee for deposit in the Trust not later than the time prescribed by federal law (including extensions) for filing the federal income tax return of an Employer for the taxable year in which the Plan Year ends, and shall be deposited in the
Participant’s Employer Matching Contributions Account as soon as practicable after it is received by the Trustee. 

  
 21 









	4.4	Employer Performance Contributions 

  

	(a)	In General. The Employer may (but shall not be required to) make Employer Performance Contributions on behalf of each Eligible Employee of up to three percent (3%) of Compensation for each Plan Year that
certain performance goals are met. The performance goals and the related performance contribution percentage shall be set by the Board of Directors or its delegates, and may be changed before the beginning of each Plan Year. 


 

	(b)	Allocation. Any Employer Performance Contribution for the Plan Year shall be payable to each Eligible Employee (or Beneficiary) who is actively employed by an Employer on December 31 of such Plan Year, or
who died, retired, became Disabled, or otherwise went on an approved leave of absence during the Plan Year. Employer Performance Contributions shall be allocated pro rata, based on an Eligible Employee’s Compensation while an Eligible Employee
during the Plan Year. Employer Performance Contributions shall be delivered to the Trustee for deposit in the Trust not later than the time prescribed by federal law (including extensions) for filing the federal income tax return of an Employer for
the year in which the Plan Year ends, and shall be deposited in the Participant’s Employer Matching Contributions Account as soon as practicable after it is received by the Trustee. If an Eligible Employee is not a Participant at the time
Employer Performance Contributions are allocated, an Employer Performance Contributions Account shall be established in the Eligible Employee’s name and invested in the “qualified default investment alternative” (as defined under
Department of Labor Regulation Section 2550.404c-5(c)) chosen by the Committee. A Participant may change his investment election at any time pursuant to Section 6.3. 


 

	4.5	Rollover Contributions 

 Without regard to any limitations on contributions set forth in this Article 4,
the Plan may receive from an Eligible Employee, in cash, any amount previously received (or deemed to be received) by him in an eligible rollover distribution. For purposes of this Section, the permitted sources for an eligible rollover distribution
include: (i) a qualified trust described in Code Section 401(a), (ii) another qualified 401(k) plan, and (iii) an individual retirement account or annuity described in Code Sections 408(a) or 408(b), solely established to hold
funds transferred from a tax qualified retirement plan under Code Section 401(a). The Plan will not accept rollover contributions in the case of a distribution to a surviving Spouse, or to a Spouse or former Spouse who is an alternate payee
under a qualified domestic relations order, as defined in Code Section 414(p). 
 The Plan may receive such amounts either directly from the Eligible
Employee or in the form of a Direct Rollover. Notwithstanding anything herein to the contrary, the Plan shall not accept any amount unless such amount qualifies as an eligible rollover distribution under Code Section 401(a)(31), and the
Eligible Employee provides evidence satisfactory to the Committee that such amount qualifies for rollover treatment. The Committee may, in its sole discretion, authorize a direct trust-to-trust transfer, rollover, or other qualified plan asset
transfer, to the extent that such transfer complies with current Internal Revenue Service regulations and does not violate any provision under ERISA. Rollover Contributions made by an Eligible Employee shall be allocated to the Eligible
Employee’s Rollover Account and, for the purposes of Article 6, shall be credited as soon as practicable after it is received by the Trustee. 

  
 22 









	4.6	Deductibility Limitation 

 No Employer Contributions may be made to the Plan in excess of the amount that
may claimed as an income tax deduction under the Code. If all or part of the Employer’s deductions for contributions to the Plan are disallowed by the Internal Revenue Service, the portion of the contributions to which that disallowance applies
shall be returned to the Employer without interest, but reduced by any investment loss attributable to those contributions, provided that the contribution is returned within one (1) year after the disallowance of deduction. For this purpose,
all contributions made by the Employer are expressly declared to be conditioned upon their deductibility under Code Section 404. 
  

	4.7	Section 402(g) Limit on Before-Tax Contributions 

  

	(a)	Limitations on Contributions. Except as permitted in Section 4.1(d), in no event shall the Before-Tax Contributions with respect to a Participant and similar contributions made on his behalf by an Employer
to all plans, contracts, or arrangements subject to the provisions of Code Section 401(a)(30) in any calendar year exceed the limitation set forth in Code Section 402(g). If a Participant’s Before-Tax Contributions in a calendar year
exceed the limitation described in this subsection, the Participant’s Before-Tax Contributions for the remainder of the calendar year will be cancelled. As of the first pay period of the calendar year following such cancellation, the
Participant’s election of Before-Tax Contributions shall again become effective in accordance with his previous election, unless the Participant changes his election as set forth in Article 3. 


 

	(b)	Return of Excess Contributions. If a Participant makes Before-Tax Contributions in excess of the dollar limitation described in subsection (a) for any calendar year, the Participant may notify the Committee
(or its designee) in writing by March 1 of the next calendar year of the excess deferrals allocated to the Plan. Upon the Committee’s (or it’s designee’s) receipt of such notice, the amount of the excess designated by the
Participant (and any earnings on such amount) will be distributed to the Participant by April 15 of such year. Excess deferrals will be adjusted for earnings using any method permitted under Treasury Regulation Section 1.402(g)-1(e). In
the event that any Before-Tax Contributions returned under this subsection were matched by Employer Matching Contributions, those Employer Matching Contributions, together with earnings, shall be forfeited and used to offset administrative expenses
or to reduce Employer Contributions. In the event those Employer Matching Contributions subject to forfeiture have been distributed to the Participant, the Employer shall make reasonable efforts to recover the contributions from the Participant.


  

	4.8	Actual Deferral Percentage Test 

  

	(a)	In General. The amount of Before-Tax Contributions contributed to the Plan for a Plan Year shall comply with the provisions of Code Section 401(k)(3), including any regulations issued thereunder, and any
subsequent IRS guidance issued under Code Section 401(k). For purposes of determining the Plan’s compliance with the foregoing, the current year testing method shall be used. 


  
 23 









	(b)	Excess Contributions. If the Committee determines that the limitation under this Section has been exceeded in any Plan Year, the following provisions shall apply: 


 

	 	(1)	The actual deferral ratio of the Highly-Compensated Employee with the highest actual deferral ratio shall be reduced to the extent necessary to meet the actual deferral percentage test or to cause such ratio to equal
the actual deferral ratio of the Highly-Compensated Employee with the next highest ratio. This process will be repeated until the actual deferral percentage test is passed. Each ratio shall be rounded to the nearest one one-hundredth of one percent
(1%) of the Participant’s Compensation. The amount of Before-Tax Contributions made by each Highly-Compensated Employee in excess of the amount permitted under his revised deferral ratio shall be added together. This total dollar amount of
excess contributions (“excess contributions”) shall then be allocated to some or all Highly-Compensated Employees in accordance with the provisions of clause (2). 


 

	 	(2)	The Before-Tax Contributions of the Highly-Compensated Employee with the highest dollar amount of Before-Tax Contributions shall be reduced by the lesser of (i) the amount required to cause that Employee’s
Before-Tax Contributions to equal the dollar amount of the Before-Tax Contributions of the Highly-Compensated Employee with the next highest dollar amount of Before-Tax Contributions, or (ii) an amount equal to the total excess contributions.
This procedure shall be repeated until all excess contributions are allocated. The amount of excess contributions allocated to a Highly-Compensated Employee, together with earnings thereon, shall be corrected in accordance with the provisions of
subsection (c). 

  

	(c)	Distribution of Excess Contributions. Any excess contributions, together with earnings thereon, allocated to a Participant shall be paid to the Participant before the close of the Plan Year following the Plan
Year in which the excess contributions were made and, to the extent practicable, within 2-1/2 months of the close of the Plan Year in which the excess contributions were made. However, any excess contributions for any Plan Year shall be reduced by
any Before-Tax Contributions previously returned to the Participant for that Plan Year. In the event any Before-Tax Contributions returned under this Section were matched by Employer Matching Contributions, such corresponding Employer Matching
Contributions, with earnings thereon, shall be forfeited and used to offset administrative expenses or to reduce Employer Contributions. In the event that any Employer Matching Contributions subject to forfeiture under this Section have been
distributed to the Participant, the Employer shall make reasonable efforts to recover such contributions from the Participant. 


  
 24 









	4.9	Qualified Nonelective Contributions 

 The Company may authorize that special “qualified nonelective
contributions” shall be made for a Plan Year, which shall be allocated in such amounts and to such Participants who are Non-Highly Compensated Employees, as the Committee shall determine. Qualified nonelective contributions shall be fully and
immediately vested, and may be taken into account in determining the actual deferral percentage or the actual contribution percentage of the Non-Highly Compensated Employees for the current Plan Year provided the contributions are contributed to the
Plan no later than the time prescribed by law for such purposes and provided the contributions are allocated in a manner that satisfies the regulations under Code Section 401(k). 

 

	4.10	Limitation on Annual Additions 

  

	(a)	In General. Contributions made on behalf of each Participant for any Limitation Year shall be subject to the following limits, and are intended to comply with the provisions of Code Section 415 and the
Treasury Regulations thereunder, the provisions of which are hereby incorporated by reference. 

  

	(b)	Definitions. For purposes of this Section: 

  

	 	(1)	“Annual Addition” means the total for the Limitation Year of: 

  

	 	(A)	all Employer Contributions, Before-Tax Contributions, forfeitures, excess amounts treated as Employer Contributions pursuant to subsection (e), After-Tax Contributions, and similar amounts under other qualified defined
contribution plans made maintained by any Employer or an Affiliate; 

  

	 	(B)	for purposes of applying the limit in Section 4.10(c)(2), amounts described in Code Sections 415(1)(1) and 419A(d)(2) allocated to the Participant. 


 

	 	(2)	“Limitation Year” means the Plan Year. 

  

	(c)	Maximum Annual Additions. The Annual Additions to a Participant’s Accounts for any Limitation Year, when added to the Participant’s Annual Additions for that Limitation Year under any other qualified
defined contribution plan of the Employer or an Affiliate, shall not exceed the lesser of: 

  

	 	(1)	$54,000 (for 2017), as adjusted for increases in the cost of living pursuant to Code Section 415(d); or 

  

	 	(2)	one-hundred percent (100%) of the Participant’s Compensation for the Limitation Year. 


Notwithstanding the provisions of this Section, if a Participant is participating in another qualified defined contribution plan of the
Employer or an Affiliate during a particular limitation year, and the Participant’s annual addition for such limitation year, before the application of the limitation set forth in this subsection exceeds that limitation, the Committee, under
uniform rules equally applicable to similarly situated Participants, shall determine how to satisfy the limitation. 

  
 25 









	(d)	Short Limitation Year. If a short Limitation Year is created because of an amendment changing the Limitation Year to a different 12 consecutive month period, the dollar limit in Section 4.10(c)(1) will not
exceed $54,000 (as adjusted pursuant to Code Section 415(d) for increases in the cost of living) multiplied by a fraction, the numerator of which is the number of months in the short Limitation Year, and the denominator of which is 12.


  

	(e)	Excess Amounts. If, for any Limitation Year, it is necessary to limit the allocation of an amount to a Participant’s Account to comply with subsection (c), the Plan: 


 

	 	(1)	first, shall refund to the Participant, to the extent necessary and as soon as is administratively feasible, the amount of After-Tax Contributions, and any earnings thereon. The Employer Matching Contributions made with
respect to such After-Tax Contributions and earnings thereon shall be held in a suspense account and used in the next Limitation Year as an Employer Matching Contribution; and 


 

	 	(2)	second, shall pay to the Participant, to the extent necessary and as soon as administratively feasible, the Before-Tax Contributions, if any, made on behalf of the Participant and any earnings thereon. The Employer
Contributions made with respect to such Before-Tax Contributions and any earnings thereon shall be held to a suspense account and used in the next Limitation Year as an Employer Matching Contribution. 


 

	4.11	Military Service 

 Notwithstanding any provisions of the Plan to the contrary, contributions, benefits,
and service credit with respect to qualified military service will be provided in accordance with the mandatory provisions of Code Section 414(u), or any other applicable federal law governing such matters. The Section is intended to extend the
full protections of USERRA to any Participant who becomes entitled thereto and it shall become effective as of December 12, 1994. 

  
 26 









	Article 5.	Vesting 

  

	5.1	Before-Tax Contributions Account, After-Tax Contributions Account, Employer Performance Contributions Account and Rollover Account 


A Participant shall at all times be one-hundred percent (100%) vested in, and have a nonforfeitable right to, his Before-Tax Contributions Account,
Catch-Up Contributions Account, After-Tax Contributions Account, Employer Performance Contributions Account, and Rollover Account. 
  

	5.2	Employer Matching Contributions Account 

  

	(a)	A Participant shall at all times be one-hundred percent (100%) vested in his Employer Matching Contributions Account upon the earliest to occur of (i) his attainment of Normal Retirement Age; (ii) the
date on which the Participant incurs a Disability; or (iii) his death while employed by an Employer. 

  

	(b)	Before the dates described in subsection (a), a Participant shall have a one-hundred percent (100%) nonforfeitable interest in his Employer Matching Contributions in accordance with the following schedule:


  

			
	 Full Years of Vesting Service
	  	Nonforfeitable Percentage
	less than 1	  	0 percent
	1	  	20 percent
	2	  	40 percent
	3	  	60 percent
	4	  	80 percent
	5 or more	  	100 percent

  

	(c)	Upon termination of employment, a Participant shall forfeit his interest in his Employer Matching Contribution Account to the extent not vested in accordance with this Section. Notwithstanding the foregoing, an Employee
of White Springs Agricultural Chemicals, Inc. will forfeit the nonvested portion of his interest in the Plan as of the fifth anniversary of his Severance from Service Date or, if earlier, as of the date his vested interest in the Plan is paid to
him. 

  

	5.3	Restoration of Forfeitures Upon Reemployment 

  

	(a)	 General Rule. If a former Participant who has suffered a forfeiture on account of his termination of
participation is reemployed before incurring five (5) consecutive one (1) year Periods of Severance and repays to the Plan all money distributed from his Employer Matching Contributions Account before sixty (60) months after such
reemployment, any amounts so forfeited (unadjusted for any increase or decrease in the value of Trust assets subsequent to the date on which the forfeiture occurred) shall be reinstated to the Participant’s Employer Matching Contributions
Account within a reasonable time after such repayment. Such reinstatement shall be made from forfeitures 



  
 27 









	 	
to the extent such forfeitures are attributable to contributions by the same Employer and earnings on such contributions; provided, however, that if such forfeitures are not sufficient to provide
such reinstatement, the reinstatement shall be made from the current year’s contribution by that Employer to the Plan. 

  

	(b)	Special Rule for Certain Employees of White Springs Agricultural Chemicals, Inc. Notwithstanding subsection (a) above, if a former Participant who was an Employee of White Springs Agricultural Chemicals,
Inc. terminates employment and the nonvested portion of his interest in the Plan is forfeited before January 1, 2015 in accordance with Section 5.2(c), the forfeited amount shall be restored to the Participant’s Account if the
Participant is rehired by making a special allocation funded from current forfeitures. The restored amount shall be credited to a separate restoration account. The Participant’s vested portion in the restoration account, at the time of the
restoration and at any relevant time thereafter, shall be the greater of: 

  

	 	(1)	the product of the Participant’s vested percentage in his Employer Matching Contributions Account, as determined under Section 5.2 and the balance in the restoration account, or 


 

	 	(2)	the product of: 

  

	 	(A)	the Participant’s vested percentage in his Employer Matching Contributions Account, as determined under Section 5.2, and 

  

	 	(B)	the excess of: 

  

	 	(i)	the sum 

  

	 	(ii)	the amount of the distribution. 

  

	5.4	Forfeitures 

 Any amounts forfeited under the Plan shall be applied to offset administrative expenses or
to reduce Employer contributions. 

  
 28 









	Article 6.	Trust, Investments and Accounting 

  

	6.1	In General 

 The Company shall maintain a Trust by entering into one or more Trust Agreements. Any Trust
Agreement is designated as, and shall constitute, a part of the Plan, and all rights that may accrue to any person under the Plan shall be subject to all the terms and provisions of such Trust Agreement. The Sponsor may modify any Trust Agreement
from time to time to accomplish the purpose of the Plan and may replace the Trustee and appoint a successor Trustee. 
  

	6.2	Trust 

 (a) In General. Subject to the discretion of the Committee to consolidate, eliminate or
create Funds, the Trustee shall establish and maintain in the Trust various Funds, which shall be invested at the direction of the Committee, Trustee, or any designated investment manager as the case may be. The Committee may establish an investment
policy for the investment of the Trust that includes uniform nondiscriminatory rules regarding a Participant’s ability to invest in one or more of the Funds and any other matters as shall be determined by the Committee in its sole discretion in
accordance with ERISA and the provisions of the Plan. Unless specifically provided otherwise, each Fund as may from time to time be established, shall be a common fund in which each Participant shall have an undivided interest in the respective
assets of the Fund. For purposes of allocation of income and valuation, each Fund shall be considered separately. No Fund shall share in the gains and losses of any other, and no Fund shall be valued by taking into account any assets or
distributions from any other. Dividends, interest, and other distributions received on the assets held by the Trustee in respect to an Fund shall be reinvested in such Fund. 
  

	(b)	Company Stock Fund. The investment Funds maintained by the Trustee shall, to the extent permitted under ERISA, include a Fund which invests exclusively (other than for the purpose of maintaining sufficient
liquidity to provide for distributions, withdrawals, and transfers under the Plan) in Company Stock, as defined in Appendix G (the “Company Stock Fund”), without regard to the diversification of assets of the Plan and Trust. The Company
desires that the Company Stock Fund be offered under the Plan to permit Participant ownership in the Company. The Company Stock Fund shall be designated as a stock bonus plan within the meaning of Code Section 401(a)(23), and an employee stock
ownership plan (“ESOP”) intended to meet the applicable requirements of Code Sections 401(a), 409 and 4975(e)(7), and ERISA Section 407(d)(6). Unless otherwise provided by the Committee, no portion of a Participant’s or
Beneficiary’s Account other than the ESOP Account (as defined in Appendix G) may be invested in the Company Stock Fund. The provisions applicable to the Company Stock Fund are set forth in Appendix G. 


 

	(c)	Cash. The Trustee may keep such amounts of cash as the Committee, in its sole discretion, shall deem necessary or advisable as part of the Trust, all within the limitations specified in the Trust
Agreement. 


  
 29 









	6.3	Investment Elections 

 A Participant shall make an investment election for contributions to his Account
in accordance with such rules as the Committee may prescribe from time to time. Contributions may be invested in increments of one percent (1%) in any one or more of the Funds such that the total equals one-hundred percent (100%). In the
absence of an affirmative investment direction from a Participant, his Accounts will be invested in a “qualified default investment alternative” (as defined under Department of Labor Regulation Section 2550.404c-5(c)) chosen by the
Committee. A Participant may change his investment election (whether elected or made by default) at any time by filing a new investment election with the Committee in the manner and time prescribed by the Committee. Such changed investment election
shall become effective as soon as administratively practicable after receipt thereof by the Committee, and shall be effective only with respect to subsequent contributions. 
  

	6.4	Transfers Between Funds 

 A Participant may elect to transfer and reallocate amounts from one Fund to
another on a daily basis, in the manner prescribed by the Committee. The transfer shall be effective as soon as practicable following the receipt of the Participant’s election by the Committee. The amount to be transferred, except for amounts
that are invested in Company Stock, shall be specified in (i) a whole percentage, (ii) a whole dollar amount, or (iii) the number of shares for transfer. For amounts invested in Company Stock, the amount to be transferred shall be
specified in the number of shares for transfer. The Committee or its designee may require that the amount to be transferred under this Section exceed a minimum amount, and such rules may provide an exception where the Participant transfers the total
value of his Accounts in the Fund from which the transfer is being made, or as otherwise prescribed by the Committee. 
  

	6.5	Imposition of Reasonable Restrictions 

 The Committee may impose reasonable restrictions on the
investment elections of Participants (or Beneficiaries or alternate payees), such as restrictions on the frequency with which that person is able to transfer funds from one Fund to another, if the Committee determines that the restrictions are
(i) necessary to comply with applicable law (e.g., securities laws), (ii) necessary to comply with rules imposed by a Fund (e.g., restrictions by a Fund intended to prevent market timing), (iii) necessary to prevent a Fund from
refusing to accept funds from this Plan, (iv) appropriate to prevent decreases in the value of the Fund for other Participants (or Beneficiaries or alternate payees), or (v) for other similar reasons. 

 

	6.6	Responsibility for Investments 

 Each Participant is solely responsible for the investment of his
Accounts. The Plan is intended to meet the requirements for a participant-directed investment plan under ERISA Section 404(c) and Department of Labor Regulation Section 2550.404c-1, and an “eligible individual account plan” as
described in ERISA Section 407(d). 

  
 30 









	Article 7.	Valuation of Accounts 

  

	7.1	Valuation 

 The Trustee shall value the Funds on each Valuation Date. Such valuation shall be conducted
pursuant to such practices and procedures as shall from time to time be adopted by the Trustee, and consistently and uniformly applied, for the valuation of each Fund. Earnings, gains, and losses (realized or unrealized) for each Fund shall be
allocated to the portion (“subaccount”) of a Participant’s Account maintained with respect to that Fund, in the same ratio that the value of the subaccount bears to the sum of the values of all Participants’ subaccounts
maintained with respect to that Fund. The Committee shall adopt rules for determining the appropriate Valuation Dates to be used to determine the amount of withdrawals and distributions. 

The Trustee shall make available to each Participant, electronically or pursuant to such other method as may be reasonably adopted by the Trustee, information
as to the share or unit values, and the aggregate values, of each Fund for the benefit of such Participant. Such information shall be made available as of the close of business on each Valuation Date. 

 

	7.2	Statement of Account 

 Each Participant shall be furnished with a statement setting forth the value of
his Accounts on a quarterly basis. 
  

	7.3	Loan Account 

 Pursuant to rules and regulations promulgated by the Internal Revenue Service, the
Committee may designate all or certain Accounts as constituting a separate contract for purposes of Code Section 72. 

  
 31 









	Article 8.	Distributions 

  

	8.1	Eligibility 

 After a Participant terminates employment with all Employers and Affiliates, or ceases
active employment on account of his termination of employment for any reason, including long-term Disability, his Accounts shall be distributed as provided in this Article. No distribution shall be made from the Plan until the Committee or its
designee has received an application for distribution from a Participant entitled to receive a distribution. The Committee may prescribe rules regarding the form of such application, the method of filing such application, and the information
required to be furnished in connection with such application. 
  

	8.2	Deferral of Benefit Payments 

  

	(a)	In General. Except as otherwise provided in this Article, a Participant may defer the commencement of his benefit payments as provided in this Section. For purposes of this Section, if a Participant does not file
an application for distribution in the manner prescribed by the Committee, he will be deemed to have elected to defer the payment of his benefit until distributions are mandated as set forth below. 


 

	(b)	Small Amounts. Notwithstanding any provision of the Plan to the contrary, if the value of the Participant’s Accounts is $1,000 or less, a lump sum payment shall automatically be made as soon as
administratively practicable following the Participant’s termination of employment. 

  

	(c)	Required Distributions. If a Participant does not timely elect a different benefit commencement date, and if such Participant’s Account is not paid sooner under another benefit payment provision pursuant to
this Article, distribution of the Participant’s Account must commence no later than his required beginning date, as described in Section 8.11. Notwithstanding any provisions of this Article 8, a Participant or Beneficiary who would have
been required to receive a distribution pursuant to Code Section 401(a)(9) and the regulations issued thereunder for the 2009 calendar year but for the enactment of Code Section 401(a)(9)(H), will not receive such required distribution
unless the Participant elects to receive the required distribution for calendar year 2009.  

  

	8.3	Required Commencement Under Code Section 401(a)(14) 

 If a Participant does not timely elect a
different benefit commencement date, and if such Participant’s Account is not paid sooner under another benefit payment provision pursuant to this Article, his Account must commence to be paid on or before the 60th day following the close of
the Plan Year in which occurs the latest of the following dates: (1) the date the Participant attains his Normal Retirement Date, (2) the 10th anniversary of the year in which the Participant commenced participation in the Plan, or
(3) the Participant’s termination date. 
  

	8.4	Spousal Consent Not Required 

 The consent of a Participant’s Spouse shall not be required to make
distributions from the Plan. 

  
 32 









	8.5	Form of Distribution 

 The normal form of payment under the Plan shall be a lump sum distribution. In
lieu of the normal form, a Participant (or his Beneficiary, in the event of the Participant’s death, or his alternate payee under a qualified domestic relations order, as defined in Code Section 414(p)), may elect from the optional
forms provided in this Section. 
  

	(a)	Installment Payments. A Participant may elect to have his Account paid in a series of monthly, quarterly, or annual payments over a period designated by the Participant. The period over which payments may be made
cannot exceed the lesser of (i) 10 years, or (ii) the Participant’s (or Beneficiary’s) life expectancy or the joint life expectancies of the Participant and his Beneficiary. Installment payments will be made in reasonably equal
amounts, except as necessary to reflect increases or decreases in the value of the Participant’s Account.  

  

	(b)	Partial Lump Sum Distribution. A Participant may elect to have his Account paid in a partial lump sum in a specified dollar amount. Only one such partial lump sum distribution may be requested during a Plan Year.
A distribution made pursuant to this subsection shall be subject to the limitations described in Section 8.11. 

 Notwithstanding
anything in this Section to the contrary, a Participant may not elect a distribution form other than those provided above unless otherwise authorized by a Supplement. 
  

	8.6	Distribution in the Form of Company Stock 

 Distribution of a Participant’s Account shall be made in
cash. If, however, at the time of distribution a portion of the Participant’s Account to be distributed is invested in the Company Stock Fund, the provisions of Appendix G shall apply, and the Participant (or Beneficiary) may elect distribution
of that portion of the Participant’s Account in one of the following ways: 
  

	(a)	entirely in cash, to the extent cash is available, or 

  

	(b)	in whole shares of stock and uninvested cash allocated to the Fund as may be necessary to represent fractional shares of such stock and other assets allocated to such Fund. Stock may be distributed only if the
Participant elects a lump sum distribution. 

  

	8.7	Notice Period 

 Except as otherwise provided in this Article, if the value of a Participant’s
Accounts exceeds $1,000, an election by the Participant to receive a distribution before age 65 shall not be valid unless the written election is made (a) after the Participant has received the notice required under Treasury Regulation
Section 1.411(a)-11(c), and (b) within a reasonable time before the effective date of the commencement of the distribution as prescribed by said regulations. If such distribution is one to which Code Sections 401(a)(11) and 417 do not
apply, such distribution may commence less than thirty days after the notice required under Treasury Regulation Section 1.411(a)-11(c) is given, provided that: the Committee clearly informs the Participant that he has a right to a period of at
least thirty days after receiving the notice to consider the decision of whether or not to elect a distribution (and, if applicable, a particular distribution option), and the Participant, after receiving the notice, affirmatively elects a
distribution. 

  
 33 









	8.8	Distribution Timing 

  

	(a)	General. Except as otherwise provided and subject to subsection (b), payments to a Participant or Beneficiary shall be made as soon as practicable following the completion of the valuation process for the
Valuation Date which determines the amount of the payment. 

  

	(b)	Deferral to Ascertain Benefit or Locate Participant. If payment cannot be made on a date it is required to be made because the Committee, after making reasonable efforts, cannot locate a Participant or
Beneficiary or the amount of the payment cannot be ascertained, a payment retroactive to the required date shall be made no later than 60 days after the earliest date on which the amount of the payment can be ascertained and the date on which the
Participant or Beneficiary has been located. 

  

	8.9	Status of Accounts Pending Distribution 

 Until his Accounts are distributed, the Participant shall
retain the investment rights described in Article 6 during the period the Account is distributed in full. Following the death of a Participant, pending distribution of the Participant’s Accounts, the Participant’s Beneficiary (or
Beneficiaries) shall retain the investment rights described in Article 6. 
  

	8.10	Distributions on Account of Death 

  

	(a)	Death Before Benefit Commencement Date. If a Participant dies before distribution of his Account has commenced, his Beneficiary shall receive a lump sum distribution of the entire value credited to his Account,
or the Beneficiary may elect installment payments over a period not to exceed the life expectancy of the Beneficiary as determined under Code Section 401(a)(9) and the applicable regulations thereunder. The Beneficiary shall make the election
in the manner and time prescribed by Committee rules. A Participant’s Beneficiary may not defer the payment of the death benefit. 

  

	(b)	Death After Benefit Commencement Date. If a Participant (or the Participant’s Spouse if distributions have commenced to such surviving Spouse) dies after the distribution of payments have commenced, his
Accounts shall be distributed to his Beneficiary at least as rapidly as under the method of distribution that was in effect at the date of the Participant’s death. 


 

	(c)	Death During Military Service. In the case of a Participant who dies while performing qualified military service, as defined under Code Section 414(u) and applicable Treasury Regulations, 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 the distribution calendar year. 


 

	 	(3)	“life expectancy” means life expectancy as computed by use of the Single Life Table in Treasury Regulation Section 1.401(a)(9)-9. 


 

	 	(4)	“Participant’s Account balance” means the Participant’s 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. 

  

	 	(5)	“required beginning date” means the later of the April 1st next following the close of the calendar year in which the Participant attains age

 35 









	(c)	Time and Manner of Distribution 

  

	 	(1)	Required Beginning Date. The Participant’s Accounts will begin to be distributed to the Participant no later than the Participant’s required beginning date. 


 

	 	(2)	Death of Participant Before Required Beginning Date. If the Participant dies before his required beginning date, the Participant’s Accounts will be distributed no later than as follows: 


 

	 	(A)	If the Participant’s surviving Spouse is the Participant’s sole designated Beneficiary, then distributions to the surviving Spouse will be made in a single lump sum distribution by December 31 of the
calendar year immediately following the calendar year in which the Participant died, or by December 31 of the calendar year in which the Participant would have attained age 70-1/2, if later.


  

	 	(B)	If the Participant’s surviving Spouse is not the Participant’s sole designated Beneficiary, then distributions to the designated Beneficiary will be made in a single lump sum distribution by December 31

Participant’s Beneficiary by December 31 of the calendar year containing the fifth anniversary of the Participant’s death. 

  

	 	(D)	If the Participant’s surviving Spouse is the Participant’s sole designated Beneficiary and the surviving Spouse dies after the Participant but before distributions to the surviving Spouse begin, this
Section 8.11(c)(2), other than Section 8.11(c)(2)(A), will apply as if the surviving Spouse were the Participant. 

  

	 	(3)	Beginning Date. For purposes of Section 8.11(c)(2) and Section 8.11(e), unless Section 8.11(c)(2)(D) applies, distributions are considered to begin on the Participant’s required beginning
date. If Section 8.11(c)(2)(D) applies, distributions are considered to begin on the date distributions are required to begin to the surviving Spouse under Section 8.11(c)(2)(A). If distributions under an annuity purchased from an
insurance company irrevocably commence to the Participant before the Participant’s required beginning date (or the Participant’s surviving Spouse before the date distributions are required to begin to the surviving Spouse under
Section 8.11(c)(2)(A)) the date distributions are considered to begin is the date distributions actually commence. 


  
 36 









	 	(4)	Forms of Distributions. Unless the Participant’s Account is distributed in the form of an annuity purchased from an insurance company or in a single sum on or before the required beginning date, as of the
first distribution calendar year distributions will be made in accordance with Sections 8.11(d) and (e). If the Participant’s Account 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. 

  

	(d)	Required Minimum Distributions During Participant’s Lifetime 

  

	 	(1)	Amount of Required Minimum Distribution For Each Distribution Calendar Year. During the Participant’s lifetime, the minimum amount that will be distributed for each distribution calendar year is the lesser
of: 

  

	 	(A)	The quotient obtained by dividing the balance in the Participant’s Account by the distribution period in the Uniform Lifetime Table set forth in Treasury Regulation Section 1.401(a)(9)-9, using the
Participant’s age as of the Participant’s birthday in the distribution calendar year; or 

  

	 	(B)	If the Participant’s sole designated Beneficiary for the distribution calendar year is the Participant’s Spouse, the quotient obtained by dividing the balance in the Participant’s Account by the number in
the Joint and Last Survivor Table set forth in Treasury Regulation Section 1.401(a)(9)-9, using the Participant’s and Spouse’s attained ages as of the Participant’s and Spouse’s birthdays in the distribution calendar year.


  

	 	(2)	Lifetime Required Minimum Distributions Continue Through Year of Participant’s Death. Required minimum distributions will be determined under this Section 8.11(d)(2) beginning with the first
distribution calendar year and up to and including the distribution calendar year that includes the Participant’s date of death. 

  

	(e)	Required Minimum Distributions After Participant’s Death 

  

	 	(1)	Death On or After Required Beginning Date 

  

	 	(A)	Participant Survived by Designated Beneficiary. If the Participant dies on or after his required beginning date 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 balance in the Participant’s Accounts 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: 

  

	 	(i)	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. 


  
 37 









	 	(ii)	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. 


 

	 	(iii)	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. 

  

	 	(B)	No Designated Beneficiary. If the Participant dies on or after his required beginning date 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 balance in the Participant’s Account 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. 

  

	 	(2)	Death Before Required Beginning Date 

  

	 	(A)	Participant Survived by Designated Beneficiary. If the Participant dies before his required beginning date 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 balance the Participant’s Account by the remaining life expectancy of the Participant’s designated Beneficiary, determined as provided in
Section 8.11(e)(1). 

  

	 	(B)	No Designated Beneficiary. If the Participant dies before his required beginning date 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 Account balances will be completed by December 31 of the calendar year containing the fifth anniversary of the Participant’s death. 


 

	 	(C)	Death of Surviving Spouse Before Distributions to Surviving Spouse Are Required to Begin. If the Participant dies before his required beginning date, the Participant’s surviving Spouse is the Participant’s
sole designated Beneficiary, and the surviving Spouse dies before distributions are required to begin to the surviving Spouse under Section 8.11(c)(2)(A), this Section 8.11(e)(2) will apply as if the surviving Spouse were the Participant.



  
 38 









	8.12	Direct Rollover of Certain Distributions 

 Notwithstanding any provision of the Plan to the contrary that
would otherwise limit a Distributee’s election under this Section, a Distributee may elect, at the time and in the manner prescribed by the Committee, to have any portion of an Eligible Rollover Distribution paid directly by the Plan to an
Eligible Retirement Plan specified by the Distributee in a Direct Rollover. 

  
 39 









	Article 9.	In-Service Withdrawals 

  

	9.1	Withdrawal of Amounts Allocated While An Employee of PCS Nitrogen Ohio, L.P. or PCS Purified Phosphates

the Plan or the Prior White Springs Plan while the Participant was an Employee of White Springs Agricultural Chemicals, Inc. 

  

	(b)	Before-Tax Contributions and Employer Performance Contributions. Upon the attainment of age 59-1/2 or after suffering a long-term Disability, a Participant may withdraw all or a portion of his Before-Tax
Contributions Account and Employer Performance Contributions Account attributable to Before-Tax Contributions and Employer Performance Contributions that were made to the Plan or the Prior White Springs Plan while the Participant was an Employee of
White Springs Agricultural Chemicals, Inc. 

  

	9.3	Hardship Withdrawals 

  

	(a)	In General. A Participant who has withdrawn the total amount available as otherwise provided under the preceding Sections of this Article may, subject to this Section, elect to withdraw all or any portion of his
Before-Tax Contributions Account attributable to Before-Tax Contributions that were made to the Plan, the Prior Nitrogen Plan or the Prior White Springs Plan while the Participant was an Employee of PCS Nitrogen Ohio, L.P., PCS Purified Phosphates
or White Springs Agricultural Chemicals, Inc., upon furnishing proof of hardship satisfactory to the Committee or its designee. A Participant shall be considered to have incurred a hardship if, and only if, he meets the requirements of subsections
(c) and (d). 


  
 40 









	(b)	Limitation on Amount of a Hardship Withdrawal. The amount of a hardship distribution from the Before-Tax Contributions Account may not exceed the sum of: 


 

	 	(1)	the total Before-Tax Contributions made on behalf of the Participant reduced by prior distributions, plus 

  

	 	(2)	the earnings credited to the Before-Tax Contributions Account as of December 31, 1988. 

  

	(c)	Immediate and Heavy Financial Need. As a condition for hardship withdrawal, there must exist with respect to the Participant an immediate and heavy financial need. Such a need will be presumed to exist if the
Participant certifies that he requires the hardship withdrawal due to one or more of the following reasons: 

  

	 	(1)	Medical Care. To pay unreimbursed expenses for medical care described in Code Section 213(d) (determined without regard to whether the expenses exceed ten percent (10%) of adjusted gross income)
previously incurred by the Participant, his Eligible Dependents (as defined below), or Beneficiary, or necessary for those persons to obtain such medical care. 


 

	 	(2)	Purchase of Principal Residence. To pay the costs directly related to the purchase of a principal residence of the Participant (excluding mortgage payments). 


 

	 	(3)	Tuition and Related Fees. To pay tuition and related educational fees, and room and board expenses (but excluding student activity fees and the costs of books, supplies and uniforms), for the next twelve months
of post-secondary education of the Participant, his Eligible Dependents, or Beneficiary. 

  

	 	(4)	Amounts Necessary to Prevent Eviction or Foreclosure. To pay amounts necessary to prevent eviction of the Participant from his principal residence or to avoid foreclosure on the mortgage of his principal
residence. 

  

	 	(5)	Burial or Funeral Expenses. To pay burial or funeral expenses of the Participant’s parents, Spouse, children, Eligible Dependents, or Beneficiary. 


 

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

  

	 	(7)	Other Expenses. The inability of the Participant to meet such other expenses, debts, or other obligations recognized by the Internal Revenue Service as giving rise to immediate and heavy financial need for
purposes of Code Section 401(k). 


  
 41 








 The amount of withdrawal may not be in excess of the amount of the immediate and heavy financial
need of the Participant, including any amounts necessary to pay any federal, state, or local income taxes and any amounts necessary to pay any penalties reasonably anticipated to result from the distribution. For purposes of this subsection,
“Eligible Dependent(s)” means the Spouse and each unmarried child or stepchild of any Participant or any other household member whom the Participant may claim as a dependent for federal income tax purposes pursuant to Code Section 152
for the Plan Year. 
 Notwithstanding anything in the Plan to the contrary, an immediate and heavy financial need will not be presumed to
exist unless the Participant elects to receive dividends in cash to the extent currently available under the Plan and all plans maintained by the Employer in accordance with Treasury Regulation Section 1.401(k)-1(d)(2). 

 

	(d)	Necessary to Satisfy Financial Need. The Participant must demonstrate that the hardship withdrawal is necessary to satisfy the financial need described in subsection (c). To demonstrate such necessity, the
Participant who requests a hardship withdrawal must certify to the Committee, on such form as the Committee may prescribe, that the financial need cannot be fully relieved: 


 

	 	(1)	through reimbursement or compensation by insurance or otherwise, 

  

	 	(2)	by reasonable liquidation of the Participant’s assets, 

  

	 	(3)	by cessation of Before-Tax Contributions, or 

  

	 	(4)	by other distributions or nontaxable (at the time of the loan) loans from the Plan or other plans of an Employer or an Affiliate (unless such plan loans would make the hardship worse) or by borrowing from commercial
sources at a reasonable rate in an amount sufficient to satisfy the need. 

 The actions listed are required to be taken to the
extent necessary to relieve the hardship, but any action which would have the effect of increasing the hardship need not be taken. For purposes of this subsection, there shall be attributed to the Participant those assets of the Participant’s
Spouse and minor children that are reasonably available to the Participant. The Participant shall furnish to the Committee such supporting documents as the Committee may request in accordance with uniform and nondiscriminatory rules prescribed by
the Committee. If, on the basis of the Participant’s certification and the supporting documents, the Committee finds it can reasonably rely on the Participant’s certification, then the Committee shall find that the requested withdrawal is
necessary to meet the Participant’s financial need. 
  

	(e)	 Suspension of Contributions. A Participant who receives a hardship withdrawal shall be prohibited from
making contributions to the Plan and all other plans of an Employer or an Affiliate for six months after receipt of a distribution described in this Section. For purposes of this subsection, all other plans of an Employer or an Affiliate shall
include stock option plans, stock purchase plans, qualified and non-qualified deferred compensation plans, and such other plans as may be designated under regulations issued 




  
 42 








 
under Code Section 401(k), but shall not include health and welfare benefit plans or the mandatory employee contribution portion of a defined benefit plan. After the expiration of the
suspension period described in this subsection, an Eligible Employee must affirmatively make a new election to participate in the Plan pursuant to Section 3.2. 
  

	9.4	Procedures and Restrictions 

 A request for a withdrawal under this Article shall be filed with the Plan
in the manner and time prescribed by the Committee or its designee, and shall be subject to rules of the Committee concerning the frequency of such withdrawals. The Committee or its designee may require that the amount of a withdrawal under this
Article exceed a minimum amount that may not exceed $1,000, and such rules may also provide exceptions where the Participant withdraws his entire Account. In addition to the restrictions imposed by this Article, the amount available for any
withdrawal shall be reduced to the extent that the Account secures any loan outstanding on the date of the withdrawal. Where a Participant’s Account is invested in more than one Fund, Committee rules shall determine the method of drawing on the
Funds. All payments to Participants under this Article shall be made in cash; provided, however, that to the extent that his Account is invested in the Company Stock Fund on the date a Participant makes a withdrawal from his Account at or after age
59-1/2 or upon his Disability, the Participant may elect to receive distribution of the amount invested in the Company Stock Fund in the form of Company Stock (as defined in Appendix G). 

  
 43 








 Article 10. Plan Loans 
  

	10.1	Availability 

 Loans shall be available upon written application and approval by the Committee or its
designee in accordance with the terms and conditions of (i) this Article 10, (ii) Appendix E (relating to Employees of PCS Nitrogen Ohio, L.P. and PCS Purified Phosphates), (iii) Appendix F (relating to Employees of White Springs
Agricultural Chemicals, Inc.), (iv) a loan policy that sets forth the terms and conditions for Plan loans, and (v) any other rules as the Committee or its designee may prescribe. 

The Committee or its designee shall apply the eligibility requirements and rules for a loan uniformly to all Participants. Nothing in this Article or an
Appendix shall require the Committee or its designee to make loans available to all Employees. 
  

	10.2	Requirements for Plan Loans 

 In addition to such rules and regulations as the Committee may adopt, any
loan shall comply with the following terms and conditions: 
  

	(a)	Application. An application for a loan shall be made in the form and manner prescribed by the Committee, whose action in approving or disapproving the application shall be final. 


 

	(b)	Loan Amount.  

  

	 	(1)	In General. The amount of any loan may not be less than the amount prescribed in Section E.3 of Appendix E, and Section F.3 of Appendix F.  


 

	 	(2)	Maximum Loan Amount. No loan will be granted under the Plan to the extent that it would cause the aggregate balance of all loans a Participant or Employee has outstanding under the Plan to exceed the lesser of:
 

  

	 	(A)	fifty percent (50%) of the balance of the Participant’s Accounts, excluding the Participant’s Employer Matching Contributions Account, Employer Performance Contributions Account and Basic Contributions
Account; or 

  

	 	(B)	$50,000, reduced by the excess, if any, of the highest outstanding loan balances of all other loans from the Plan during the 12 month period ending on the day before the loan was made. 


 

	(c)	Loan Terms. The period of repayment and the repayment provisions for any loan shall be arrived at by mutual agreement between the Committee and the Participant; provided, however, that the period of repayment
shall not extend beyond five (5) years in the case of a General Purpose loan or twenty (20) years in the case of a Home Loan.  


  
 44 









	(d)	Substantially Level Repayment. As provided in Appendix E and Appendix F, all loans will be subject to a substantially level repayment schedule, as determined by the Committee. Notwithstanding anything in the Plan
or an Appendix to the contrary, the substantially level requirement does not apply for a period, not longer than one (1) year, that an Employee is on a bona fide leave of absence without pay, provided when the Employee returns to active pay
status, the loan (including interest that accrues during the leave of absence) must be repaid by the latest date permitted under Code Section 72(p)(2)(B) and the amount of the installments due after the leave ends, must not be less than the
amount required under the original terms of the loan. Pursuant to Code Section 414(u), Committee rules may also permit the suspension of the obligation to repay a loan for a period during which the Participant is performing services in the
uniformed services of the United States. 

  

	(e)	Promissory Note. A loan shall be evidenced by a promissory note payable to the Plan in such form and containing such terms as the Committee shall direct, subject to the provisions of this Article.


  

	(f)	Interest Rate. All loans will bear interest at a fixed rate determined by the Committee based upon the daily prime feed provided by Reuters as of the close of business on the last day of the month, plus two
percent (2%), unless such rate would not be “reasonable” as defined by ERISA Section 408(b)(3), in which case a “reasonable” rate of interest will be used.  


The new loan interest rate will be effective after a nightly cycle on the first business day of the following month (or quarter) and will apply to all new
loan types initiated. Fidelity will calculate the interest rate based on the prime rate and the plan specified delta. 
  

	(g)	Loan Restrictions; Discontinuance. The Committee may impose reasonable restrictions on the ability of an individual to take out a loan from the Plan, or on the terms of such loan, to the extent required to comply
with applicable law. In addition, the Committee reserves the right to stop granting loans at any time. 

  

	10.3	Definitions 

 The following definitions apply to the terms used in this Article: 

 

	(a)	“General Purpose Loan” means a loan that is not a Home Loan. 

  

	(b)	“Home Loan” means a loan to be used to acquire a dwelling unit that, within a reasonable time after the loan is made, will be used as the principal residence of the Participant or Employee. The Plan
shall require evidence that a loan will be used for such purpose. Committee rules may deem a loan as incurred to acquire a principal residence if expenditures to acquire the residence are made within 90 days before or after the date that the loan is
made. A loan will not qualify as a Home Loan if it is used to construct, rehabilitate, or improve a residence. A loan to repay an existing loan from a third party will be deemed to be for a principal residence if the proceeds of the third-party loan
were used to acquire a principal residence and the Plan loan is made within the 90 day period before or after the expenditure to acquire the residence. 


  
 45 









	Article 11.	Benefit Claims 

  

	11.1	Inquiries and Applications for Benefits 

  

	(a)	All inquiries concerning the Plan or present or future rights to benefits under the Plan and all applications for benefits under the Plan shall be submitted to the Committee in the form and manner prescribed by the
Committee. The Committee shall have the sole discretionary authority to grant or deny benefits under the Plan. Benefits under the Plan will be paid only if the Committee decides in its discretion that the applicant is entitled to them.


  

	(b)	If any Participant, Spouse or Beneficiary disagrees with the Committee’s response to such individual’s inquiry or application for benefits, the Participant, Spouse or Beneficiary shall notify the Committee in
writing and shall request a review of such response. Any such notice shall be treated as a claim for benefits hereunder. 

  

	11.2	Denial of Claims 

 In the event that any claim for benefits under the Plan is denied in whole or in part,
the Committee shall notify the claimant in writing of such denial and of the claimant’s right to a review thereof. Such written notice shall set forth the following information in a manner calculated to be understood by the claimant: 

 

	(a)	the specific reason or reasons for the denial; 

  

	(b)	specific reference 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 of why such material or information is necessary; and 


 

	(d)	an explanation of the Plan’s procedure for review of the denied or partially denied claim, including the claimant’s right to bring a civil action under ERISA Section 502(a) following an adverse benefit
determination on review. 

 Such written notice shall be given to the claimant within 90 days after the Committee receives the claim, unless
special circumstances require an extension of time, up to an additional 90 days, for processing the claim. If such an extension is required, written notice of the extension shall be furnished to the claimant before the end of the initial 90 day
period. Such notice of extension shall indicate the special circumstances requiring the extension of time and the date by which the Committee expects to render its decision on the claim for benefits. 

 

	11.3	Review of Denied Claims 

  

	(a)	Appeal Request. The Committee shall have the authority to act with respect to any appeal from a denial of a claim for benefits. 


  
 46 








 Any person whose claim for benefits is denied, in whole or in part, or such person’s duly
authorized representative, may appeal from such denial by submitting a request for a review of the claim to the Committee within 60 days after receiving written notice of such denial from the Committee. A claimant or the claimant’s authorized
representative will have, upon request and free of charge, reasonable access to, and copies of, all documents, records and other information relevant to the claimant’s claim for benefits, and may submit written comments, documents, records and
other information in writing within the same 60 day period. A request for review shall set forth all of the grounds on which it is based, all facts in support of the request and any other matters that the claimant deems pertinent. The Committee may
require the claimant to submit any additional facts, documents or other material as it may deem necessary or appropriate in making its review. 
  

	(b)	Decision on Review. The Committee shall act on each request for review within 60 days after receipt thereof unless special circumstances require an extension of time, up to an additional 60 days, for processing
the request. If such an extension is required, written notice of the extension shall be furnished to the claimant within the initial 60 day period. The Committee shall consider the claim, and all comments, documents, records and other information
submitted by the claimant relating to the claim, without regard to whether such information was submitted or considered in the initial benefit determination. 


The Committee shall give prompt, written notice of its decision to the claimant. In the event that the Committee affirms the denial of the
claim for benefits, in whole or in part, such notice shall set forth, in a manner calculated to be understood by the claimant: 
  

	 	(1)	the specific reason or reasons for the adverse determination; 

  

	 	(2)	specific reference to pertinent Plan provisions on which the adverse determination is based; 

  

	 	(3)	a statement that the claimant is entitled to receive, upon request and free of charge, reasonable access to, and copies of, all documents, records, and other information relevant to the claimant’s claim for
benefits; and

action under ERISA Section 502(a).

The Committee may require a claimant who wishes to submit additional information in connection with an appeal from the denial of benefits to do so at the claimant’s own expense. 


  
 47 









	11.4	Deadline to File Claim 

 To be considered timely under the Plan’s claim and review procedures, a
claim must be filed with the Committee within one (1) year after the claimant knew or reasonably should have known of the principal facts upon which the claim is based. If or to the extent that the claim relates to a failure to effect a
Participant’s or Beneficiary’s investment directions or a Participant’s election regarding contributions, a claim must be filed with the Committee within thirty (30) days after the claimant knew or reasonably should have known of
the principal facts upon which the claim is based. 
  

	11.5	Exhaustion of Remedies 

 No legal action for benefits under the Plan shall be brought unless and until
the claimant: 
  

	(a)	Has submitted an application for benefits in accordance with this Article; 

  

	(b)	Has been notified by the Committee that the application is denied; 

  

	(c)	Has filed a written request for a review of the application; and 

  

	(d)	Has been notified in writing that the Committee has affirmed the denial of the application. 

 Notwithstanding
the foregoing, if any claimant is not provided the notification(s) required by Sections 11.2 or 11.3 within the time periods set forth in those Sections, the claimant may bring a legal action for benefits under the Plan without any further
administrative review of the claim. 
  

	11.6	Deadline to File Legal Action 

 No legal action to recover Plan benefits or to enforce or clarify rights
under the Plan under ERISA Sections 502 or 510 or under any other provision of law, whether or not statutory, may be brought by any claimant on any matter pertaining to this Plan unless the legal action is commenced in the proper forum before the
earlier of: 
  

	(a)	thirty (30) months after the claimant knew or reasonably should have known of the principal facts on which the claim is based, or 


 

	(b)	six (6) months after the claimant has exhausted the claim and review procedures. 

 If or to the extent that
the claim relates to a failure to effect a Participant’s or Beneficiary’s investment directions or a Participant’s election regarding contributions, the thirty (30) month period shall be nineteen (19) months. 

 

	11.7	Knowledge of Fact by Participant Imputed to Beneficiary 

 For the purpose of applying the deadlines to
file a claim or a legal action, knowledge of all facts that a Participant knew or reasonably should have known shall be imputed to every claimant who is or claims to be a Beneficiary of the Participant or otherwise claims to derive an entitlement by
reference to the Participant for the purpose of applying the previously specified periods.

	Article 12.	Administration 

  

	12.1	Appointment of Committee 

  

	(a)	The Committee (also known as the Employee Benefits Committee) shall be the “plan administrator” and “named fiduciary” of the Plan, as defined under ERISA. The Committee shall consist of not fewer
than three members, to be appointed by the Board of Directors or its chairman. Each member of the Committee may resign, or may be removed at any time by the Board of Directors or its chairman (with or without cause), and, in the event of the
removal, death or resignation of any member, his successor shall be appointed by the Board of Directors or its chairman. In the event a vacancy or vacancies shall occur, the remaining member or members of the Committee shall act as the Committee
until the Board of Directors or its chairman fills the vacancy or vacancies. The Committee may appoint or designate other fiduciaries and may allocate fiduciary responsibilities among fiduciaries, including members of the Committee.


  

	(b)	No person shall be ineligible to be a member of the Committee because he is, was, or may become entitled to benefits under the Plan, or because he is a director and/or officer of an Employer or an Affiliate; provided,
that no member of the Committee shall participate in any determination by the Committee relating specifically to his own benefits under the Plan. 

  

	(c)	If a member of the Committee (or a subcommittee) is an Employee, the member will serve without compensation for his services as a member. The Company may reimburse the member for expenses properly and actually incurred.


  

	12.2	Powers and Authority; Action Conclusive 

  

	(a)	The Committee shall be responsible for the administration of the Plan, and shall have the exclusive right, responsibility and discretionary authority with respect to the construction, interpretation, application or
administration of the Plan and eligibility for Plan benefits including, but not limited to, the discretionary power and authority to find facts in connection with any decision made hereunder. 


 

	(b)	The Committee shall be responsible for making appropriate provision for the investment and reinvestment of the Trust and shall have the exclusive right, responsibility and authority with respect thereto.


  

	(c)	The Committee shall have all powers necessary or helpful for the carrying out of its responsibilities and to determine all questions of fact, and the decisions or actions of the Committee in good faith in respect of any
matter hereunder shall be final, conclusive and binding upon all parties concerned, including, without limitation, any and all Employees, Participants, Spouses, Beneficiaries, heirs, distributees, estates, executors, administrators and assignees.
Any determination made by the Committee shall be given deference in the event it is subject to judicial review and shall be overturned only if it is arbitrary and capricious. 


  
 50 









	(d)	The Committee may delegate to one or more of its members the right to act on its behalf in any one or more matters connected with the administration of the Plan. 


 

	12.3	Manner of Action 

 A majority of the members of the Committee then in office shall constitute a quorum
for the transaction of business. The Committee shall select from its members a chairman and shall appoint from its members or otherwise a secretary. The Committee may act by vote or consent of the majority of its members then in office and may
establish its own procedures. Upon concurrence in writing of a majority of the members, action of the Committee may be taken without a meeting. The Committee may authorize one or more of its members or any of its agents to execute or deliver any
instrument on its behalf, and may employ such counsel, auditors, and other specialists and such clerical and other services as required or desired in carrying out the provisions of the Plan. 

 

	12.4	Subcommittees, Counsel and Agents 

 The Committee may appoint from its members such subcommittees (or one
or more such members), with such powers as the Committee shall determine. The Committee may employ such counsel (including legal counsel, who may be counsel for an Employer or an Affiliate) and agents and such clerical and other services as it may
require in carrying out the provisions of the Plan, and may charge the fees, charges and costs resulting from such employment as an expense to the Company or to the Plan, to the extent permitted by law. Persons serving on the Committee or any such
subcommittee shall be fully protected in acting or refraining from acting in accordance with the advice of legal or other counsel. 
  

	12.5	Appointment of Investment Manager 

 The Committee shall have the authority to select, appoint, and
monitor the performance of one or more investment managers (within the meaning of ERISA Section 3(38)) to manage or advise as to the investment of all or any portion of the Trust. Each such investment manager shall satisfy the requirements of
ERISA and shall act pursuant to the terms of the applicable investment management agreement or investment advisory agreement. An investment manager shall acknowledge in writing delivered to the Plan and to the trustee its appointment as a fiduciary
of the Trust. The investment manager may be terminated at will. 
 An investment manager appointed under this Section shall have sole investment
responsibility for that portion of the Trust which it is appointed to manage. Other fiduciaries of the Plan shall be under no duty to question any direction or lack of direction of any investment manager, but may act, and shall be fully protected in
acting in accordance with each such direction of an investment manager. Other fiduciaries of the Plan shall have no responsibility for the investment of any asset of the Trust, the management of which has been delegated to an investment manager, or
liability for any loss to or diminution in value of the Trust resulting from any action directed, taken, or omitted by an investment manager. 

  
 51 









	12.6	Designation of Other Fiduciaries 

 The Committee may designate in writing other persons to carry out a
specified part or parts of its responsibilities hereunder (including the power to designate other persons to carry out a part of such designated responsibility). Any such designation shall be accepted by the designated person, who shall acknowledge
in writing that he is a fiduciary with respect to the Plan.

 The Committee shall make all reports or other filings necessary to meet the
reporting and disclosure requirements that are the responsibility of “plan administrators” under ERISA. 
  

	12.8	Records 

 All resolutions, proceedings, acts, and determinations of the Committee shall be recorded by
the secretary of the Committee or under his supervision, and all such records, together with such documents and instruments as may be necessary for the administration of the Plan, shall be preserved in the custody of the secretary. 

 

	12.9	Electronic and Other Media 

 Notwithstanding any provision of the Plan to the contrary, to the extent
permitted by law, the Committee may use electronic media in addition to or in lieu of other media, as it deems necessary or appropriate, to conduct transactions, maintain records, make disclosures, reports, and filings, and to otherwise administer
the Plan. 
  

	12.10	Automatic and Default Elections 

 To the extent permitted by law, Committee rules may provide that a
Participant (or Beneficiary) election will remain in force until the Participant notifies the Committee (in the manner and time prescribed by the Committee) of a modification of such a continuing election. If the Plan requires an affirmative
election, the Committee rules may specify that a failure to make a timely affirmative election will be deemed to be a direction to the Plan to take such action specified by the Committee rules. If the Committee adopts a rule pursuant to this
Section, it shall be communicated to the affected Participants and Beneficiaries in a manner that assures timely receipt and a reasonable period for the Participant to modify a continuing election or to make an affirmative election. 

 

	12.11	Expenses of Administration 

 The compensation of the Trustee, any reasonable and proper attorneys’
or management fee incurred in the administration of the Trust or other reasonable and proper Plan expenses shall be paid pursuant to Section 15.4. 

  
 52 









	12.12	Limited Liability and Indemnification 

  

	(a)	In General. Except as otherwise provided by law, no person who is a member of the Committee or who is an Employee, officer and/or director of an Employer or an Affiliate (“Indemnified Person(s)”), shall
incur any liability whatsoever on account of any matter connected with or related to the Plan or the administration of the Plan, unless such person shall have acted in bad faith, or have willfully neglected his duties, in respect of the Plan. The
Company shall indemnify and save each such person harmless against any and all loss, liability, claim, damage, cost and expense which may arise by reason of, or be based upon, any matter connected with or related to the Plan or the administration of
the Plan (including, but not limited to, any and all expenses whatsoever reasonably incurred in investigating, preparing or defending against any litigation, commenced or threatened, or in settlement of any such claim whatsoever) to the fullest
extent permitted by the law. 

  

	 	(1)	An Indemnified Person shall be indemnified under this Section only if he provides written notice to the Employer in the manner and time prescribed by the Company, of any claim asserted against or any investigation of
the Indemnified Person that relates to the Indemnified Person’s responsibilities with respect to the Plan. The notice must be provided promptly after the Indemnified Person becomes aware of the claim or investigation. No indemnification shall
be provided under this Section to the extent that the Employer is materially prejudiced by the unreasonable delay of the Indemnified Person in notifying the Employer of the claim or investigation. 


 

	 	(2)	An Indemnified Person shall be indemnified under this Section with respect to attorney’s fees, court costs or other litigation expenses or any settlement of such litigation only if the Indemnified Person agrees to
permit the Company or Employer to select counsel and to conduct the defense of the lawsuit, and agrees not to take any action in the lawsuit that the Company or Employer believes would be prejudicial to the interests of such Company or Employer.
Subject to the consent of the Indemnified Person, the Employer may enter into a settlement or other agreement to compromise a claim, demand, action or proceeding which has given rise to a notice of claim for indemnity hereunder. 


 

	 	(3)	If the Indemnified Person refuses to consent to the terms of a proposed settlement or compromise which is otherwise acceptable to the Employer, any amount awarded against the Indemnified Person in excess of the amount
for which settlement or compromise could have been made by the Employer shall not be recoverable, and in such event the Employer shall only be responsible for costs, charges and expenses up to the time at which settlement could have been made.


  

	 	(4)	No Indemnified Person, including an Indemnified Person who has terminated employment, shall be indemnified under this Section unless he makes himself reasonably available to assist the Employer with respect to the
matters at issue, and agrees to provide documents, testimony, information, materials, or other forms of assistance that the Employer shall reasonably request. 

  

	 	(5)	No Indemnified Person shall be indemnified under this Section with respect to any action or failure to act that is judicially determined to constitute or be attributable to the gross negligence or willful misconduct of
the Indemnified Person. 


  
 53 









	 	(6)	Payments of indemnity under this Section shall be made only from the assets of the Employer and shall not be made directly or indirectly from Plan assets. The provisions of this Section shall not preclude such further
indemnities as may be available under insurance purchased by the Employer or as may be provided by an Employer under any by-law, agreement or otherwise, provided that no expense shall be indemnified under this Section that is otherwise indemnified
by an Employer or by an insurance contract purchased by an Employer. To the extent permitted by law, the Employer shall be subrogated to all rights which the Indemnified Person may have under all policies of insurance or other contracts pursuant to
which the Indemnified Person may be entitled to reimbursement of, or indemnification in respect of, all or any part of the costs, charges and expense which are borne by the Employers pursuant to this agreement. 


 

	(b)	Advance Payment of Defense Costs. Except for the indemnities provided for in subsection (c), the Employers will advance and pay all reasonable costs, charges and expenses as they are incurred, provided however:


  

	 	(1)	that no such advancement shall be made unless and until the Indemnified Person has provided to the Employer a written affirmation of his good faith belief that he has met the standard of conduct necessary for
indemnification by the Employer; 

  

	 	(2)	that no such advancement shall be made unless and until the Indemnified Person has provided to the Employer (in the time and manner prescribed by the Company), a written statement by or on behalf of the Indemnified
Person to repay all amounts so advanced pursuant to this subsection, if it is subsequently determined that the Indemnified Person has not met the standard of conduct necessary for indemnification by the Employer; 


 

	 	(3)	that if the Indemnified Person subsequently receives indemnification or reimbursement for all or part of any costs, charges or expenses from a source or sources other than the Employer, the amounts so advanced and paid
by the Employer shall be repaid by the Indemnified Person to the Employer upon request, to the extent that the Indemnified Person receives indemnification or reimbursement from such other source(s). 


 

	(c)	Breach or Non-Fulfillment By Employer. In addition to the indemnities provided for under this Section, the Employer shall defend, indemnify and hold an Indemnified Person harmless from any loss, liability,
damage, or expense, including reasonable attorney’s fees, arising in connection with or resulting from any breach or non-fulfillment or any agreement on the part of the Employer pursuant to this Section. 


 

	12.13	Reliance on Information 

 The members of the Committee and any Employer or Affiliate and their respective
officers, directors and employees, shall be entitled to rely upon all tables, valuations, certificates, opinions and reports furnished by any actuary, accountant, trustee, insurance company, counsel, physician or other expert who shall be engaged by
the Committee, an Employer or an Affiliate, and the 

  
 54 








 
members of the Committee and any Employer or Affiliate and their respective officers, directors and Employees, shall be fully protected in respect of any action taken or suffered by them in good
faith in reliance thereon, and all action so taken or suffered shall be conclusive upon all persons affected thereby. 
  

	12.14	Instructions to Trustee 

 The Committee shall provide appropriate written instructions in accordance with
the Trust Agreement to enable the Trustee to make the distributions provided for in the Plan. 
  

	12.15	Genuineness of Documents 

 The Committee, Employer and Affiliates and their respective officers,
directors and employees, shall be entitled to rely upon any notice, request, consent, letter or other document believed by them or any of them to be genuine, and to have been signed or sent by the proper person, and shall be fully protected in
respect of any action taken or suffered by them in good faith in reliance thereon. 
  

	12.16	Proper Proof 

 In any case in which an Employer or the Committee shall be required under the Plan to take
action upon the occurrence of any event, they shall be under no obligation to take such action unless and until proper and satisfactory evidence of such occurrence shall have been received by them. 

  
 55 









	Article 13.	Management of Funds 

  

	13.1	Trust Agreement 

 All funds of the Plan shall be held by the Trustee appointed from time to time by the
Sponsor under a Trust Agreement adopted, or as amended, by the Sponsor for use in providing the benefits of the Plan and paying expenses not directly paid by the Employer. The Employer shall have no liability for the payment of benefits under the
Plan or for the administration of the funds paid over to the Trustee. 
  

	13.2	Exclusive Benefit Rule 

 Except as otherwise provided in the Plan, no part of the corpus or income
of the Trust shall be used for, or diverted to, purposes other than for the exclusive benefit of Participants and other persons entitled to benefits under the Plan and paying the expenses of the Plan not paid directly by the Employer. No person
shall have any interest in, or right to, any part of the earnings of the funds of the Plan, or any right in, or to, any part of the assets held under the Plan, except as and to the extent expressly provided in the Plan. 

  
 56 









	Article 14.	Amendment, Termination, and Merger 

  

	14.1	Amendments to Comply with Law 

 The Company reserves the right to amend the Plan at any time to take
effect retroactively or otherwise, in any manner in which it deems necessary or desirable for the purpose of complying with the provisions of the Code and ERISA and the regulations and rulings thereunder affecting the tax-qualified status of the
Plan and the deductibility of Employer Contributions thereto. 
  

	14.2	Suspension of Contributions; Termination of Plan 

  

	(a)	Suspension of Contributions. It is the Company’s expectation that the Plan and payment of contributions hereunder will be continued indefinitely, but continuance of the Plan by the Company is not assumed as
a contractual obligation, and the Company reserves the right to modify or permanently discontinue contributions hereunder at any time. In the case of complete discontinuance of contributions to the Plan, the rights of affected Participants to their
Accounts as of the date of the termination or discontinuance shall be nonforfeitable. The Company shall not be liable for the payment of any benefits under the Plan and all benefits hereunder shall be payable solely from the assets of the Trust.


  

	(b)	Termination. The Company may terminate the Plan at any time. Upon complete termination or partial termination of the Plan, the entire interest of each of the affected Participants shall become nonforfeitable.
Upon termination of the Plan, Before-Tax Contributions, with earnings thereon, shall only be distributed to Participants if (i) neither an Employer nor an Affiliate establishes or maintains an alternative defined contribution plan and
(ii) payment is made to the Participants in the form of a lump sum distribution (as defined in Code Section 402(d)(4), without regard to clauses (i) through (iv) of paragraph (A), subparagraph (B), or subparagraph
(F) thereof). For purposes of this paragraph, an “alternative defined contribution plan” is a defined contribution plan (other than an ESOP) or a simplified employee pension as defined in Code Section 408(k) (“SEP”))
which exists at the time the Plan is terminated or within the 12 month period beginning on the date all assets are distributed. However, in no event shall a defined contribution plan be deemed an alternative plan if fewer than two percent
(2%) of the employees who are eligible to participate in the Plan at the time of its termination are or were eligible to participate under another defined contribution plan of an Employer or an Affiliate (other than an ESOP or a SEP) at any
time during the period beginning 12 months before and ending 12 months after the date of the Plan’s termination. 

  

	14.3	Authority to Amend 

 The Company may amend the Plan at any time by a written resolution or other written
instrument approved by the Board of Directors. The Committee is authorized to exercise the Company’s authority under this Section through a written resolution or other written instrument , without approval of the Board of Directors with respect
to any amendment does not: 
  

	(a)	deprive the Company or the Employers of their ability to make tax deductible contributions to the Plan pursuant to the Code; 


  
 57 









	(b)	violate Section 14.5 (concerning the exclusive benefit and anti-cutback rules); 

  

	(c)	have the effect of terminating the Plan; 

  

	(d)	increase the cost of providing benefits under the Plan by an amount estimated to be more than $200,000 for each of the first five full Plan Years that the amendment would be effective, unless the amendment is for
conforming the Plan with legislation, governmental regulations, rules, or interpretive bulletins expressing a public policy or condition with which the Plan must comply; 


 

	(e)	revise this Article to increase the Committee’s authority to amend the Plan or derogate from the authority of the Board of Directors; or 


 

	(f)	confer any special advantage whether economic or otherwise, whether present or contingent, on the Committee or its members. 

  

	14.4	Form of Amendment 

 Unless otherwise provided in the Plan, the amendment shall be made by an instrument
in writing, signed by a duly authorized officer or officers of the Company (as appropriate), certifying that the amendment has been authorized by the Board of Directors or the Committee. 

 

	14.5	Limitations 

 The provisions of this Article are subject to the following restrictions: 

 

	(a)	No amendment to the Plan may operate either directly or indirectly to give an Employer an interest in a Fund or property held by the Trustee under the terms of the Plan, or to permit corpus or income of the Trust to be
used for or diverted to purposes other than the exclusive benefit of the Participants and their Beneficiaries. 

  

	(b)	Except as permitted by Treasury Regulations or to the extent necessary to conform to laws and regulations or to the extent permitted by any applicable law or regulation, no amendment may operate either directly or
indirectly to deprive any Participant of his nonforfeitable interest in his Accounts as they are constituted at the time of the amendment. 

  

	(c)	No amendment shall change any vesting schedule unless each Participant who has completed three (3) or more years of continuous service is permitted to elect to have the nonforfeitable percentage of his Accounts
computed under the Plan without regard to such amendment. The period for making such election shall commence no later than the date of the adoption of such amendment and shall expire no earlier than 60 days after the latest of the following dates:
(A) the date the Plan amendment is adopted, (B) the date the Plan amendment becomes effective, or (C) the date the Participant is issued written notice of the Plan amendment by the Committee. Notwithstanding the foregoing, no election
need be offered to a Participant whose nonforfeitable percentage of his Accounts cannot at any time be lower than such percentage determined without regard to such amendment. 


  
 58 









	14.6	Merger, Consolidation, or Transfer 

 The Plan may not be merged or consolidated with, and its assets or
liabilities may not be transferred to, any other plan unless each person entitled to benefits under the Plan would, if the resulting plan were then terminated, receive a benefit immediately after the merger, consolidation, or transfer that is equal
to or greater than the benefit he would have been entitled to receive immediately before the merger, consolidation, or transfer if the Plan had then terminated. In the event that a Participant ceases to be eligible to participate in the Plan, but
becomes eligible to participate in another tax-qualified plan sponsored by an Employer or an Affiliate, the Committee may direct, with or without the Participant’s consent, the transfer of the Participant’s Account to the other plan
sponsored by an Employer or Affiliate. 
  

	14.7	Participation by Affiliates 

  

	(a)	The Company may extend the Plan to any Affiliate. An Affiliate may become a Participating Employer pursuant to a resolution adopted by the Board of Directors. The Affiliate shall transmit a copy of the resolution to the
Company. 

  

	(b)	Each Affiliate to whom the Plan has been extended irrevocably gives and grants to the Company full and exclusive power conferred upon it by the terms of the Plan and Trust Agreement to take or refrain from taking any
and all action which such Affiliate might otherwise take or refrain from taking with respect to the Plan, including sole and exclusive power to exercise, enforce or waive any rights whatsoever which such Affiliate might otherwise have with respect
to the Trust, and each such Affiliate, by adopting this Plan, irrevocably appoints the Company its agent for such purposes. Neither the Trustee nor the Committee nor any other person shall have any obligation to account to any such Affiliate or to
follow the instructions of or otherwise deal with any such Affiliate, the intention being that all persons shall deal solely with the Company as if it were the sole company which had adopted this Plan. 


 

	(c)	Any Affiliate shall be deemed conclusively to have assented to any amendment of the Plan pursuant to this Article without the necessity of any affirmative action on the part of such Affiliate. 


 

	(d)	Any Affiliate may terminate this Plan with respect to its own employees by resolution of its board of directors, if authorized to do so by the Board of Directors of the Company, or any person so duly authorized by the
Board of Directors 

  

	(e)	Each Affiliate shall furnish information and maintain such records with respect to its Participants as called for hereunder, and its determinations and notifications with respect thereto shall have the same force and
effect as comparable determinations by the Company with respect to its Participants. 

  

	(f)	If a Participant receives Compensation during a Plan Year from more than one Employer, the total amount of such Compensation shall be considered for the purposes of the Plan, and the respective Employers and Affiliates
shall share in contributions to the Plan on account of said Participant based on the Compensation paid to such Participant by the Employer or Affiliate. 


  
 59 









	(g)	Each Affiliate shall pay such part of the Plan’s necessary expenses incurred in the administration of the Plan as the Company shall determine. 


 

	(h)	An Affiliate may with consent of the Board of Directors withdraw from the Plan by giving written notice of its intention to the Company and the Trustee, unless a shorter notice shall be agreed to by the Company.


  

	(i)	If an Affiliate already maintains a defined contribution plan covering employees who will be covered by this Plan, such plan may be merged into this Plan. 


  
 60 









	Article 15.	General Provisions 

  

	15.1	Nonalienation 

 Except as required by applicable law, no Account or benefit under the Plan shall in any
manner be anticipated, assigned (either at law or in equity) or alienated, and any attempt to do so shall be void. However, payment shall be made in accordance with the provisions of any judgment, decree, or order that creates for, or assigns to, a
Spouse, former Spouse, child or other dependent of a Participant the right to receive all or a portion of the Participant’s benefits under the Plan for the purpose of providing child support, alimony payments, or marital property rights to that
Spouse, child, or dependent, is made pursuant to a State domestic relations law, does not require the Plan to provide any type of benefit, or any option, not otherwise provided under the Plan, and otherwise meets the requirements of ERISA
Section 206(d), as amended, as a “qualified domestic relations order,” as determined by the Committee. 
 Notwithstanding anything herein to
the contrary, the above shall not apply to an order or requirement to pay funds to the Plan arising under a judgment or conviction for a crime involving the Plan or under a civil judgment entered by a court in an action alleging a violation of Part
4 of ERISA to the extent permitted under Code Section 401(a)(13)(C) and ERISA Section 206(d)(4), or the creation, assignment or recognition of a right to any benefit payable with respect to a Participant pursuant to a domestic relations
order which is determined by the Committee to be a qualified domestic relations order as defined in Code Section 414(p) and ERISA Section 206(d). 
  

	15.2	Missing Persons 

 If the Committee is unable to locate a proper payee within one (1) year after an
Account becomes payable after taking reasonable steps to locate the payee, the Committee may treat the balance credited to the Account as a forfeiture; however, if a claim for benefits is subsequently presented by a person entitled to a payment, the
forfeited amount shall be reinstated to the Account upon verification of the claim, except for those amounts that have been paid pursuant to an escheat or other applicable law. Forfeitures restored under this Section shall be paid from current
forfeitures, and if insufficient, from an additional Employer Contribution. 
  

	15.3	Incapacity 

 If the Committee shall find that a Participant or other person entitled to a benefit under
the Plan is unable to care for his affairs because of illness or accident or is a minor, the Committee may direct that any benefit due to such Participant or other person, unless a claim shall have been made for the benefit by a duly-appointed legal
representative, be paid to his guardian, conservator, Spouse, dependent, or such other person as determined by the Committee, and such distribution so made shall be a complete discharge of the liabilities of the Plan with respect to the Participant.


  
 61 









	15.4	Plan Expenses 

 The Company or the Employer may, in its sole and absolute discretion, pay expenses
authorized and incurred in the administration of the Plan, but is not required to do so. Any such expenses not paid by the Company or the Employer shall be paid from the Trust. Notwithstanding the foregoing, brokerage fees, transfer taxes, and other
expenses incident to the purchase or sale of securities and other investments by the Trustee shall be deemed to be part of the cost of such securities and investments, or deducted in computing the proceeds of a sale, as the case may be. 

 

	15.5	Termination of Employment 

 Nothing contained in the Plan shall be construed to give any Employee the
right to be retained in the service of an Employer or an Affiliate or to interfere with the right of an Employer or Affiliate to discharge any Employee at any time. The Committee has the exclusive right to determine whether an Employee has
terminated for the purpose of the Plan and to determine the date of a termination. 
  

	15.6	Information 

 Each Participant, Beneficiary, or other person entitled to a benefit, before any benefit
shall be payable to him or on his account under the Plan, shall file with the Committee the information that it shall require to establish his rights and benefits under the Plan. 

 

	15.7	Withholding Taxes 

 The Employer or Trustee may withhold from a Participant’s compensation or any
payment under the Plan any taxes required to be withheld with respect to contributions or benefits under the Plan and such sum as the Employer or Trustee may reasonably estimate as necessary to cover any taxes for which they may be liable and which
may be assessed with respect to contributions or benefits under the Plan. 
  

	15.8	Requirement to Be in Written Form 

 Various notices provided by the Employer or Committee, and various
elections made by a Participant are required to be in written form. Except as otherwise provided under Internal Revenue Service or Department of Labor regulations or other guidance, these notices and elections may be conveyed through an electronic
system. 
  

	15.9	Elections 

 Any elections, notifications, or designations made by a Participant pursuant to the
provisions of the Plan shall be made in the form and manner prescribed by the Committee and in a time determined by the Committee under rules uniformly applicable to all Eligible Employees similarly situated. The Committee reserves the right to
change from time to time the time and manner for making elections, notifications, and designations by Participants under the Plan if it determines after due deliberation that such action is justified in that it improves the administration of the
Plan. In the event of a conflict between the provisions for making an election, notification, or designation set forth in the Plan and such new administrative procedures, those new administrative procedures shall prevail. 

  
 62 









	15.10	Recovery of Overpayment 

  

	(a)	General. If the Plan makes an overpayment or pays a benefit in error, the Plan has the right at any time, as elected by the Committee, to offset the amount of that overpayment from a future payment under the
Plan, recover that overpayment from the person to whom it was made, a combination of both, or pursue any other lawful means of recovering such overpayment. 

  

	(b)	Lien. Any person in receipt of a payment from the Plan promises to reimburse the Plan for any overpayment. Any person in receipt of any benefit paid but not owed has an obligation to immediately notify the
Committee of the overpayment and to return the overpaid benefits to the Plan. The Plan possess a lien on any benefit paid but not owed under the terms of the Plan. The lien is enforceable regardless of the reason for the mistake in payment or the

 Appendix E. Plan Loan Provisions — Employees of PCS Nitrogen Ohio, L.P. and PCS Purified Phosphates

 E.1 Eligibility. A Participant who is actively employed by an Employer or an Affiliate shall be eligible to request a loan for any reason in
accordance with Article 10 of the Plan and this Appendix. 
  

	E.2	Frequency 

  

	(a)	A Participant may only have one loan outstanding at any time, whether such loan is a Home Loan or a General Purpose Loan (as defined in Section 10.3 of the Plan), and no loan may be made to a Participant who
already has another outstanding loan from any tax-qualified plan sponsored by the Employer or an Affiliate. Notwithstanding the foregoing, the Plan’s limit on the number of outstanding loans shall not apply to any loans made to a Participant
before January 1, 2017; provided, however, that any Participant who has one or more loans outstanding as of January 1, 2017 shall not be allowed to receive another loan under the Plan until all such loans are repaid in full.


  

	(b)	A Participant may not take out a new loan until 12 months have passed from the date the Participant repaid a prior loan in full. 


E.3 Loan Amount. A Participant eligible to request a loan may borrow an amount of at least $1,000, as long as the amount of the loan does not exceed the
limitation on loans described in Section 10.2(b)(2) of the Plan.  
 E.4 Funding of a Loan. Upon the approval of a loan request, the Plan
shall liquidate all or a portion of the Funds held in the Participant’s Accounts in the order prescribed by Committee rules. Any of a Participant’s Accounts other than the Participant’s Employer Matching Contributions Account,
Employer Performance Contributions Account and Basic Contributions Account may be used to fund a loan to the Participant. 
 If any Account to be
liquidated is invested in more than one Fund, the amount of a particular Fund to be liquidated is the product of the total amount to be liquidated under the Account and a fraction with a numerator equal to the amount of the Account invested in the
Fund and a denominator equal to the total balance credited to the Account. 
 The proceeds from the liquidation of the investments will be credited to a
Loan Account that is a subaccount of the Participant’s Accounts. For the purpose of the allocation of gains, losses and earnings of the Fund, a Loan Account is deemed to be invested only in a loan to the Participant and shall be increased by
interest at the loan interest rate and decreased by the portion of each payment allocable to the Loan Account. No in-service distribution may be made from an Account in an amount that would exceed the excess of the total balance credited to the
Account over the amount of the Loan Account under that Account. 
 Upon the receipt of the promissory note described in 10.2(c) of the Plan, a loan shall be
made from the Loan Account to the Participant. 

  
 71 








 E.5 Repayments. Repayment of the loan principal and payment of the interest thereon will be made by
approximately equal payments, with payments made at least quarterly, that will permit the loan to be fully amortized over the term of the loan. A Participant shall make required payments by payroll deductions in each payroll period. If a
Participant’s pay is insufficient to make payments in full, the amount of the deficiency shall be paid by ACH (automated clearing house system for electronic funds transfer) or in such other manner as is acceptable to the Committee. A
prepayment of the entire remaining balance of the loan and accrued interest may be made at any time without penalty. A prepayment of a portion of the remaining balance may be made to the extent permitted by Committee rules. 

The portion of each payment that is attributable to repayment of the principal of a loan will reduce a Participant’s Loan Account under each Account in
the order that is converse to that prescribed pursuant to Section E.4 and will be invested in accordance with the Participant’s current investment direction in accordance with Article 6 of the Plan. 

E.6 Security and Default. A Participant’s obligation to repay a loan and interest thereon shall be secured by his Accounts. If a Participant fails
to make a required payment and the Committee determines that the loan is in default, the unpaid balance of the loan and accrued interest shall be deducted from the Loan Account and, if necessary, from the remaining portion of each Account in the
converse order of that prescribed pursuant to Section E.4 until the total amount of the unpaid balance and accrued interest has been reached. The promissory note shall then be canceled. Notwithstanding the foregoing, no loans will be secured by the
Participant’s Accounts in an amount greater than fifty percent (50%) of the value of the balance of the Account of such Participant at the time such loan was made. The amount deducted from the Accounts shall be treated as a distribution to
the Participant. No amount may be deducted from the Accounts until an event that would otherwise entitle the Participant to a distribution from that Account.  

E.7 Default Upon Termination. A Participant who has an outstanding loan and is entitled to a distribution under the Plan but elects to defer such
distribution under Section 8.2 may elect to continue to make payments on the loan on a monthly basis according to a revised amortization schedule as prepared by the Committee to avoid a loan default. If a terminated Participant subsequently
fails to make a required payment and the Committee determines that the loan is in default, the provisions of Section E.6 shall apply. 

  
 72 








 Appendix F. Plan Loan Provisions—Employees of White Springs Agricultural Chemicals, Inc. 

F.1 Eligibility. A Participant who is actively employed by an Employer or an Affiliate shall be eligible to request a loan for any reason in accordance
with Article 10 of the Plan and this Appendix. 
  

	F.2	Frequency 

  

	(a)	An Employee may only have one loan outstanding at any time, whether such loan is a Home Loan or a General Purpose Loan (as defined in Section 10.3 of the Plan), and no loan may be made to an Employee who already
has another outstanding loan from any tax-qualified plan sponsored by the Employer or an Affiliate. Notwithstanding the foregoing, the Plan’s limit on the number of outstanding loans shall not apply to any loans made to an Employee before
January 1, 2017; provided, however, that any Employee who has one or more loans outstanding as of January 1, 2017 shall not be allowed to receive another loan under the Plan until all such loans are repaid in full. 


 

	(b)	A Participant may not take out a new loan until 12 months have passed from the date the Participant repaid a prior loan in full. 


F.3 Loan Amount. An Eligible Employee or former Participant shall be able to borrow an amount of at least $1,000, in increments of $100, as long as the
amount of the loan does not exceed the limitation on loans described in Section 10.2(b)(2) of the Plan.  
 F.4 Source of Loan Funds and
Valuation. The amount needed to provide the principal amount of the loan shall come from a liquidation of the Funds. The amounts held in the Employee’s Before-Tax Contributions Account, Catch-Up Contributions Account, Rollover Account and
After-Tax Contributions Account, shall be liquidated pro rata from such Funds, in accordance with rules promulgated by the Committee. Account balances liquidated from all Funds will be valued at the closing value for the date on which the loan is
processed. A Participant’s Employer Matching Contributions Account and Employer Performance Contributions Account are not available for loans. 

F.5 Loan Account. The Committee shall establish a Loan Account for the Employee, and shall credit the account with an amount equal to the principal
amount of the loan granted. Each repayment of the principal on the loan received by the Trustee from the Employee shall reduce the balance credited to the Loan Account. 

F.6 Repayments. Repayments of the loan principal and interest shall be made through regular payroll deductions, with payments subject to a substantially
level repayment schedule, as determined by the Committee, with payments to be made at least quarterly over the term of the loan. The Employee will be required to complete a payroll deduction authorization form for the amount of the repayments, which
shall then be irrevocable throughout the term of the loan. Employees who are paid monthly, bi-weekly/semi-monthly, and weekly will have twelve (12), twenty-four (24) and forty-eight (48) periodic payroll deductions, respectively, for each
year of the term of the loan.  

  
 73 








 Periodic loan repayments shall be credited to the Employee’s Accounts in the following order, in the same
proportions within each such Account as the Employee’s current contributions are being invested in the Fund, until all amounts which were liquidated for the loan principal amount from such Accounts has been repaid: 

 

	(a)	After-Tax Contributions Account; 

  

	(b)	Rollover Account; 

  

	(c)	Employer Matching Contributions Account; 

  

	(d)	Before-Tax Contributions Account; and 

  

	(e)	Employer Performance Contributions Account. 

 If an Employee is not currently contributing to the Plan, all
repayments will be credited in the same proportions within each such Account as the latest investment election on file for the Employee, or as otherwise determined by the Committee, until all amounts which were liquidated for the loan principal
amount from such Accounts has been repaid. If no investment election is on file, all repayments will be made to the Fund designated by Committee rules, until all amounts which were liquidated for the loan principal amount from those Accounts have
been repaid. Any accrued interest on the loan balances in the various Accounts will be credited to the Account to which the related principal repayment is credited. 

The Employee may make a prepayment of all or a portion of the outstanding principal loan balance at any time. 

F.7 Delinquent Payments. A loan shall be considered delinquent if the Employee fails for any reason to make a regularly scheduled repayment, whether by
payroll deduction or otherwise, within thirty (30) days after the date such payment is due. 
 At the time that an Employee’s outstanding
loan balance is considered delinquent, if the Employee is at least age 59-1/2, the outstanding loan balance shall be treated as a distribution from the Account which may be taxable to the Employee. If the Employee is under age 59-1/2 at the time the
loan becomes delinquent, the outstanding loan balance shall be treated as a withdrawal from the Account, which shall be taxable: 
  

	(a)	to the extent the outstanding loan balance is attributable to the Employee’s After-Tax Contributions Account, and/or 

  

	(b)	to the extent the outstanding loan balance is attributable to the Employee’s Employer Matching Contributions Account or Rollover Account, if permissible, up to the amount which is available for withdrawal.


 In general, delinquent loans shall be defaulted on the last day of the calendar quarter following the calendar quarter in which the
Employee has made his last repayment to the Plan. 

  
 74 








 Any excess outstanding loan balance, which is not satisfied by Sections F.7(a) and (b) above, shall
automatically be subject to offset from any subsequent withdrawals from the Employee’s Account. 
 F.8 Default. A loan shall be declared in
default when the Employee is declared bankrupt, and unable to make subsequent repayments. At the time of the default: 
  

	(a)	if the Employee is age 59-1/2 or older, the outstanding loan balance shall be treated as a distribution, or 

  

	(b)	if the Employee is under age 59-1/2, the outstanding loan balance shall be treated as an in-service withdrawal. 


F.9 Default Upon Termination. A Participant who has an outstanding loan and is entitled to a distribution under the Plan but elects to defer such
distribution under Section 8.2 may elect to continue to make payments on the loan on a monthly basis according to a revised amortization schedule as prepared by the Committee to avoid a loan default. If a terminated Participant subsequently
fails to make a required payment and the Committee determines that the loan is in default, the provisions of Sections F.7 and F.8 shall apply.

	(b)	Tender Offer Direction. Each Participant (or his Beneficiary) shall have the sole and exclusive right to direct the Trustee in writing as to the manner in which to respond to a tender or exchange offer with
respect to shares of Company Stock allocated to such Participant’s ESOP Account. 

  

	 	(1)	Participant Information. Within a reasonable time of the commencement of a tender offer, the Committee shall use its best efforts to distribute to each Participant copies of any pertinent material supplied by the
tender offeror or the Company, together with a request for the Participant’s instructions pertaining to tender of the applicable shares.  

  

	 	(2)	Trustee Action. Upon timely receipt of such instructions, the Trustee shall respond as instructed with respect to shares of Company Stock allocated to such Participant’s ESOP Account. A Participant’s
instructions to the Trustee shall be held by the Trustee in strict confidence and shall not be divulged or released to any person, including officers or Employees of the Company. Except as provided by law, if the Trustee does not receive timely
instruction from a Participant as to the manner in which to respond to such a tender or exchange offer, the Trustee shall not tender or exchange any shares of Company Stock for which the Participant has the right of direction.


  

	(c)	Treatment of Proceeds. The Trustee shall aggregate numbers representing Participants’ instructions and shall tender such shares in accordance with such instructions. The proceeds of any shares of Company
Stock tendered in accordance with this Section which are purchased and paid for by the tender offeror shall be credited to the Fund or Funds elected by the Participant pursuant to rules established by the Administrator. In the event all shares
of Company Stock tendered by Participants are not purchased pursuant to the tender offer, the Committee is authorized to allocate the proceeds of the whole and fractional shares purchased from all such Participants pro rata, based upon the
aggregate shares tendered by each Participant. 


  
 79 









	(d)	Named Fiduciary. For the purpose of this Section, each Participant (or Beneficiary) is, hereby designated a “named fiduciary” within the meaning of ERISA Section 403(a)(1). 


 

	G.8	Distributions 

  

	(a)	Commencement. A Participant is entitled to a distribution from the ESOP Account at the time prescribed by the Plan, but no later than the period prescribed by Code Section 409(o). 


 

	(b)	Distribution Form. A Participant shall have the right to elect to commence distribution of his ESOP Account balance in any form permitted by Section 8.5. Unless the Participant elects otherwise, his ESOP
Account shall be distributed in substantially equal periodic payments (but not less frequently than annually) over a period not longer than the greater of: 

  

	 	(1)	five (5) years, or 

  

	 	(2)	in the case of a Participant with an ESOP Account balance in excess of $1,015,000, as adjusted, five (5) years plus one (1) additional year (but not more than five (5) additional years) for each $200,000,
as adjusted, or fraction thereof by which such balance exceeds $1,015,000, as adjusted. 

 The dollar amounts specified in
subsection (2) shall be adjusted for changes in the cost of living as prescribed by the Internal Revenue Service in accordance with Code Section 409(o)(1)(C)(ii). 
  

	(c)	Distribution in Company Stock. Any distribution of a Participant’s ESOP Account that would otherwise be made in cash, shall, if the Participant so elects, be made in Company Stock; provided, however, that
fractional shares shall not be distributed and, instead, the cash value of any fractional share shall be distributed. 

  

	G.9	Put Option if Company Stock is Not Readily Tradable 

 In accordance with Code Sections 409(h)(4),
(5) and (6), this Section shall apply if Company Stock ceases to be readily tradable on an established market. 
  

	(a)	Acquisition and Disposition of Stock. The Trustee shall purchase and sell Non-Publicly Traded Stock at its fair market value. The Committee shall determine the fair market value of Company Stock based upon the
value determined by an independent appraiser within the meaning of Code Section 401(a)(28)(C). 


  
 80 









	(b)	Participant Put Option 

  

	 	(1)	When Required. If a Participant receives a distribution of Company Stock and either: 

  

	 	(A)	the Company Stock ceases to be readily tradable on an established market, or 

  

	 	(B)	the Company Stock is subject to a trading limitation under federal or state securities law, or regulations thereunder, or an agreement which would make the Company Stock not as freely tradable as stock not subject to
such limitation, 

 then the Company Stock distributed to the Participant (or Beneficiary) must be subject to a put option as
described in this Section that permits the holder of the put option to require the Company to repurchase the Company Stock. 
  

	 	(2)	Holder of Put. The put option shall be exercisable by the Participant or the Beneficiary, by the donees of either, or by a person (including an estate or its distributee) to whom the Company Stock passes by
reason of the death of the Participant or the Beneficiary. 

  

	 	(3)	Responsibility for Put. The holder of the put option shall be entitled to put the Company Stock to the Company. The Committee, however, shall have the authority to assume the rights and obligations of the Company
at the time the put option is exercised by directing the Trustee to repurchase the Company Stock. Under no circumstances may the put option bind the Plan. If it is known that federal or state law will be violated by the Company’s honoring the
put option, the put option must permit the Company Stock to be put, in a manner consistent with such law, to a third party (for example, an Affiliate of the Company or a shareholder other than the Plan) that has, and is expected to continue to have,
a substantial net worth. 

  

	 	(4)	Duration of Put. The put option shall be exercisable only during the 60 day period immediately following the date of the distribution of the Company Stock, and if the put option is not exercised during that
period, it can be exercised for an additional 60 days in the following Plan Year. 

  

	 	(5)	Manner of Exercise. A put option is exercised by the holder notifying the Company in writing that the option is being exercised, in the time and manner prescribed by the Committee. 


 

	 	(6)	Price. The exercise price for a put option shall be the fair market value of the Company Stock as determined by an independent appraiser within the meaning of Code Section 401(a)(28)(C). 


 

	 	(7)	Payment Terms and Restrictions. The terms of payment for the sale of Company Stock pursuant to a put option shall be as provided in the put option and may be either paid in a lump sum or in installments as
provided by the Committee. 


  
 81 









	 	(A)	If Lump Sum Distribution Made. If the Company is required to repurchase Company Stock that was distributed to the Participant as a lump sum distribution of the Participant’s entire account balance, the
requirement of this subsection shall be treated as met if: 

  

	 	(i)	the amount to be paid for the Company Stock is paid in substantially equal periodic payments (not less frequently than annually), 

  

	 	(ii)	the payments are made over a period beginning not later than 30 days after the exercise of the put option described in subsection (4) and not exceeding five (5) years, and 


 

	 	(iii)	there is adequate security provided and reasonable interest paid on the unpaid amounts referred to in clause (i). 

  

	 	(B)	If Installment Payments Made. If the Company is required to repurchase Company Stock that was distributed to the Participant in installments, the requirement of this subsection shall be treated as met if the
amount to be paid for the Company Stock is paid not later than 30 days after the exercise of the put option described in subsection (4). 

  

	 	(8)	Nonterminable Right. The provisions of this Section shall continue to apply even if the ESOP ceases to be an ESOP within the meaning of Code Section 4975(e)(7). 


 

	G.10	Offset of Pension Benefit 

 Amounts credited to a Participant’s ESOP Account may not be taken into
account (i.e., for purposes of any “floor offset” arrangement) in determining the Participant’s benefit under any defined benefit pension plan qualified under Code Section 401(a), in accordance with ERISA Sections 407(a) and (b).
