 Exhibit 4.5 
 Amendment Number 4 
 to 

PCS U.S. Employees’ Savings Plan for Collectively Bargained Employees 

(As Amended and Restated Effective as of January 1, 2012) 
 WHEREAS, PCS Administration (USA), Inc. (“Sponsor”) is the sponsor of the PCS U.S. Employees’ Savings Plan for Collectively Bargained Employees (“Plan”), a qualified
defined contribution plan maintained pursuant to Section 401(a) of the Internal Revenue Code of 1986, as amended; 

WHEREAS, the Sponsor desires to amend the Plan to (i) modify the Plan’s default beneficiary designation provisions in
the event no beneficiary designation is in effect at the time of a participant’s death, or no designated beneficiary survives the participant; (ii) clarify the maximum amount of combined catch-up contributions and before-tax contributions
a participant may make to the Plan for any given calendar year; (iii) clarify that rollover contributions will be taken into account when determining whether the small sum cashout threshold has been met and (iv) clarify that catch-up
contributions are an available Plan loan source with respect to eligible employees of White Springs Agricultural Chemicals, Inc.; and 
 WHEREAS, pursuant to Article 14 of the Plan, the Sponsor may amend the Plan at any time and has authorized the undersigned officer to execute this Amendment. 

NOW, THEREFORE, BE IT RESOLVED, effective as of January 1, 2013, the Plan is hereby amended as follows: 

 

	1.	Section 2.1(g) is amended in its entirety to read as follows: 

  

	 	“(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 or an authorized representative of the Plan.


 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: 
  

	 	(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.” 
  

	2.	Section 4.1(d) is amended in its entirety to read as follows: 

  

	 	“(d)	 Catch-Up Contributions. Notwithstanding anything in the Plan to the contrary, a Participant who (i) will attain age 50 before the close of
a given Plan Year; and (ii) with respect to whom no other Before-Tax Contributions (without regard to this paragraph (d)) may be made to the Plan for such Plan Year by reason of the application of any limitation or other restriction described
in the federal income tax laws or the terms of the Plan may elect to make additional Catch-Up Contributions in increments of one percent (1%) of Compensation in accordance with, and subject to the limitations of, Code Section 414(v) (e.g.,
up to $5,500 for 2013 and 2014, and thereafter adjusted under the Code and by the Secretary of the 



  
 2 









	 	
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 seventy-five percent (75%) of the Participant’s Compensation for any given Plan Year. 

 A Participant’s Catch-Up Contribution election will be effective on the first day of the 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.” 
  

	3.	Section 8.2(b) is amended in its entirety to read as follows: 

  

	 	“(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.” 

  

	4.	Appendix F is amended by revising Section F.4 in its entirety to read as follows: 

 “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 Employees’
Before-Tax Contributions Account, Catch-Up Contributions Account, Employer Matching Contributions Account (to the extent vested), Rollover Account, Employer Performance Contributions 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.”
