rescind administrative and interpretive rules and regulations related to the Plan, (ii) delegate its duties under the Plan to such agents as it may appoint from time to time, and (iii) make all other determinations, perform all other acts
and exercise all other powers and authority necessary or advisable for administering the Plan, including the delegation of those ministerial acts and responsibilities as the Administrator deems appropriate. The Administrator shall have complete
discretion and authority with respect to the Plan and its application except to the extent that discretion is expressly limited by the Plan. The Administrator may correct any defect, supply any omission, or reconcile any inconsistency in the Plan in
any manner and to the extent it deems necessary or desirable to carry the Plan into effect, and the Administrator will be the sole and final judge of that necessity or desirability. The determinations of the Administrator on the matters referred to
in this Section 3(a) will be final, conclusive and binding. 
 (b) Manner of Exercise of Authority. Any action of, or
determination by, the Administrator will be final, conclusive and binding on all persons, including the Company, its owners, each Participant, or other persons claiming rights from or through a Participant. The express grant of any specific power to
the Administrator, and the taking of any action by the Administrator, will not be construed as limiting any power or authority of the Administrator. The Administrator may delegate to officers or managers of the Company, or committees thereof, the
authority, subject to such terms as the Administrator will determine, to perform such functions, including administrative functions, as the Administrator may determine. The Administrator may appoint agents to assist it in administering the Plan.

 (c) Limitation of Liability. The Administrator will be entitled to, in good faith, rely or act upon any report or other
information furnished to him or her by any officer or employee of the Company, the Company’s legal counsel, independent auditors, consultants or any other agents assisting in the administration of the Plan. The Administrator and any officer or
employee of the Company acting at the direction or on behalf of the Administrator will not be personally liable for any action or determination taken or made in good faith with respect to the Plan and will, to the fullest extent permitted by law, be
indemnified and held harmless by the Company with respect to any such action or determination. 
 4. Eligibility.
The employees of the Company listed on the Eligible Employee Schedule as Tier I Employees or Tier II Employees are eligible to receive the benefits described in this Plan subject to the terms and conditions contained herein. A Tier I Employee or
Tier II Employee’s participation in the Plan is expressly conditioned on the execution of a Participation Letter.

 5. Plan Benefits. 

(a) Termination without Cause; Constructive Termination. In the event that during the Protection Period a Participant’s
employment is terminated by the Employer without Cause or due to the Participant’s death or Disability or by the Participant due to Constructive Termination, the Participant will be entitled to receive: 

 

	 	(i)	the Accrued Payments; 

  

	 	(ii)	the Cash Severance Amount; and 

  

	 	(iii)	the Continuation Benefit. 

 (b) Severance Conditions. A Participant’s right to receive the Cash Severance Amount and the Continuation Benefit payable pursuant to Section 5(a)(ii) and 5(a)(iii) is expressly
conditioned upon the Participant having met the Severance Conditions. If the Severance Conditions have not been met prior to the 60th day following the Date of Termination, the Participant shall forfeit any right to the Cash Severance Amount and the
Participant’s continued receipt of the Continuation Benefit shall cease as of such date. 
 (c)
Timing of Payments. Subject to the Severance Conditions and Section 6, the Cash Severance Amount shall be paid in a single lump sum no later than the 65th day following the Participant’s Date of Termination. 

(d) COBRA Rights. Nothing in this Plan shall operate to reduce, or be construed as reducing, a Participant’s group health plan
continuation rights under the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”), in any manner and, upon the end of the Continuation Period, the Participant, if otherwise eligible, shall be entitled
to elect COBRA continuation coverage for the full period applicable as if the last date of the Continuation Period were the date of the Participant’s termination of employment. 

6. Effect of Severance Rights under Employment Agreements. The Cash Severance Amount provided for under
Section 5(a)(ii) shall be in lieu of any severance amounts due in connection with a termination of employment pursuant to a Participant’s Employment Agreement (other than amounts for base salary and any other wages earned but unpaid
through the Date of Termination). Notwithstanding the foregoing, (a) in the event a Participant’s Employment Agreement provides for severance payments upon termination of employment in excess of the Cash Severance Amount (determined as of
the Date of Termination) and the Participant satisfies the conditions set forth in his or her Employment Agreement to receive such severance pay, the Participant shall be entitled to receive only the severance amounts due pursuant to the
Participant’s Employment Agreement and shall not be entitled to receive the Cash Severance Amount and (b) in the event a Participant’s Employment Agreement provides for payment of severance amounts in excess of the Section 409A
Exempt Amount (determined as of the Date of Termination) or that otherwise constitute a payment pursuant to a “nonqualified deferred compensation plan” (as defined in Section 409A of the Code), all severance amounts payable pursuant
to the terms of the applicable Employment Agreement shall be paid in the amounts and, subject to Section 8(i), at the times set forth in the Employment Agreement, shall reduce the Cash Severance Amount payable pursuant to Section 5(a)(ii)
and the remaining portion of the Cash Severance Amount, if any, will be payable pursuant to Section 5(c).

 7. Claims for Benefits. 

(a) Initial Claim. In the event that a Participant or his estate claims (a “claimant”) to be eligible for a
payment under the Plan or claims any other rights under the Plan, such claimant must complete and submit such claim forms and supporting documentation as will be required by the Administrator, in its sole and absolute discretion. In connection with
the determination of a claim, or in connection with review of a denied claim, the claimant may examine the Plan and any other pertinent documents generally available to Participants that are specifically related to the claim. A written notice of the
disposition of any such claim will be furnished to the claimant within 90 days after the claim is filed with the Administrator. Such notice will refer, if appropriate, to pertinent provisions of the Plan, will set forth in writing the reasons for
denial of the claim, if a claim is denied (including references to any pertinent provisions of the Plan), and, where appropriate, will describe any additional material or information necessary for the claimant to perfect the claim and an explanation
of why such material or information is necessary. If the claim is denied, in whole or in part, the claimant will also be notified of the Plan’s claim review procedure and the time limits applicable to such procedure. 

(b) Request for Review. Within 90 days after receiving written notice of the Administrator’s disposition of the claim, the
claimant may file with the Administrator a written request for review of his claim. In connection with the request for review, the claimant will be entitled to be represented by counsel and will be given, upon request and free of charge, reasonable
access to all pertinent documents for the preparation of his claim. If the claimant does not file a written request for review within 90 days after receiving written notice of the Administrator’s disposition of the claim, the claimant will be
deemed to have accepted the Administrator’s written disposition, unless the claimant was physically or mentally incapacitated so as to be unable to request review within the 90 day period. 

(c) Decision on Review. After receipt by the Administrator of a written application for review of an initial claim determination,
the Administrator will review the claim taking into account all comments, documents, records and other information submitted by the claimant regarding the claim without regard to whether such information was considered in the initial benefit
determination. The Administrator will notify the claimant of its decision by delivery via certified or registered mail to the claimant’s last known address. A decision on review of the claim will be made by the Administrator within 45 days of
receipt of the written request for review. If special circumstances require an extension of the 45 day period, the Administrator will so notify the claimant and a decision will be rendered within 90 days of receipt of the request for review. In any
event, if a claim is not determined by the Administrator within ninety (90) days of receipt of written submission for review, it will be deemed to be denied. The decision of the Administrator will be provided to the claimant as soon as possible
but no later than five days after the benefit determination is made. The decision will be in writing and will include the specific reasons for the decision presented in a manner calculated to be understood by the claimant and will contain references
to all relevant Plan provisions on which the decision was based. Such decision will also advise the claimant that he may receive upon request, and free of charge, reasonable access to and copies of all documents, records and other information
relevant to his claim and will inform the claimant of his right to file a civil action under Section 502(a) of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), in the case of an adverse decision
regarding his appeal. The decision of the Administrator will be final, conclusive and binding.

 8. General Provisions. 

(a) Taxes. The Company or one of its Affiliates, as applicable, is authorized to withhold from any payments made hereunder amounts
of withholding and other taxes due or potentially payable in connection therewith, and to take such other action as the Company or one of its Affiliates, as applicable, may deem advisable to enable the Company or one of its Affiliates, as
applicable, and Participants to satisfy obligations for the payment of withholding taxes and other tax obligations relating to any payments made under this Plan. 
 (b) Offset. The Company may set off against, and each Participant authorizes the Company to deduct from, any payments due to the Participant, or to his estate, heirs, legal representatives, or
successors, any amounts which may be due and owing to the Company or an affiliate by the Participant, whether arising under this Plan or otherwise; provided that no such offset may be made with respect to amounts payable that are subject to the
requirements of Section 409A of the Code unless the offset would not result in a violation of the requirements of Section 409A of the Code. 
 (c) Term of the Plan; Amendment and Termination. During the Protection Period, the Plan may not be amended or modified in any manner that would in any way adversely affect the benefits or
protections provided hereunder to any individual who is a Participant, without the prior written consent of a Participant. This Plan shall terminate on the 18-month anniversary of the Closing unless otherwise determined by the Board or its
successor. 
 (d) Successors. The Plan shall bind and inure to the benefit of and be enforceable by the parties hereto and
their respective successors, permitted assigns, heirs and personal representatives and estates, as the case may be. Neither the Plan nor any right or obligation hereunder of any party may be assigned or delegated without the prior written consent of
the other party hereto; provided, however, that the Company may assign this Plan to any of its affiliates and a Participant may direct payment of any benefits that will accrue upon death. A Participant shall not have any right to pledge,
hypothecate, anticipate, or in any way create a lien upon any payments or other benefits provided under the Plan; and no benefits payable under the Plan shall be assignable in anticipation of payment either by voluntary or involuntary acts, or by
operation of law, except by will or pursuant to the laws of descent and distribution. The Plan shall not confer any rights or remedies upon any person or legal entity other than the parties hereto and their respective successors and permitted
assigns. 
 (e) Unfunded Obligation. All benefits due a Participant under this Plan are unfunded and unsecured and are
payable out of the general funds of the Company. 
 (f) Limitation on Rights Conferred Under Plan. Neither the Plan nor
any action taken hereunder will be construed as (i) giving a Participant the right to continue in the employ or service of the Company or an affiliate; (ii) interfering in any way with the right of the Company or any affiliate to terminate
a Participant’s employment or service at any time; or (iii) giving a Participant any claim to be treated uniformly with other employees. 

  
 8 

 (g) Nonexclusivity of the Plan. The adoption of the Plan by the Company will not be
construed as creating any limitations on the power of the Company to adopt such other incentive arrangements as it may deem desirable. Except as otherwise expressly provided herein, nothing contained in the Plan will be construed to prevent the
Company from taking any action which is deemed by the Company to be appropriate or in its best interest, whether or not such action would have an adverse effect on the Plan or any payments made under the Plan. No employee, beneficiary or other
person will have any claim against the Company as a result of any such action. Any action with respect to the Plan taken by the Administrator, the Company, or any designee of the foregoing shall be conclusive upon all Participants and beneficiaries
entitled to benefits under the Plan. 
 (h) Severability. If any provision of the Plan is held to be illegal or invalid
for any reason, the illegality or invalidity will not affect the remaining provisions of the Plan, but such provision will be fully severable and the Plan will be construed and enforced as if the illegal or invalid provision had never been included
herein. 
 (i) Application of Section 409A of the Code. The amounts payable pursuant to Section 5 of this Plan
are intended to comply with the short-term deferral exception and/or separation pay exception to Section 409A of the Code. To the extent that a Participant is a “specified employee” within the meaning of the Treasury Regulations
issued pursuant to Section 409A of the Code (the “Section 409A Regulations”) as of the Participant’s Date of Termination, no amount that constitutes a deferral of compensation which is payable on account of the
Participant’s separation from service (including, for purposes of clarity, amounts payable under such Participant’s Employment Agreement) shall be paid to the Participant before the date (the “Delayed Payment Date”)
which is first day of the seventh month after the Participant’s Date of Termination or, if earlier, the date of the Participant’s death following such Date of Termination. All such amounts that would, but for this Section 8(i), become
payable prior to the Delayed Payment Date will be accumulated and paid on the Delayed Payment Date. No interest will be paid by the Company with respect to any such delayed payments. For purposes of Section 409A of the Code, each payment or
amount due under this Plan shall be considered a separate payment, and a Participant’s entitlement to a series of payments under this Plan is to be treated as an entitlement to a series of separate payments. All taxable reimbursements provided
hereunder that are deferred compensation subject to the requirements of Section 409A of the Code shall be made not later than the calendar year following the calendar year in which the expense was incurred, except as otherwise provided in
Treasury Regulation § 1.409-3(i)(1)(iv)(B). Any such taxable reimbursements or any taxable in-kind benefits provided in one calendar year shall not affect the expenses eligible for reimbursement or in-kind benefits to be provided in any
other taxable year nor shall such amounts be subject to liquidation 
 (j) Governing Law. The Plan shall be governed and
construed in accordance with ERISA, and where not pre-empted by ERISA, the laws of the State of Missouri, without regard to conflicts of laws principles thereof. 
 (k) Word Usage. Words used in the masculine shall apply to the feminine, where applicable, and wherever the context of the Plan dictates, the plural shall be read as the singular and the singular
as the plural. 

  
 9 

 (l) Status/Named Fiduciary. The Plan is intended to qualify for the exemptions under
Title I of ERISA provided for plans that are unfunded and maintained primarily for the purpose of providing deferred compensation for a select group of management or highly compensated employees. The Administrator shall be the named fiduciary for
purposes of the Plan. 
 (m) ERISA Rights. As a participant in the Plan, Participants are entitled to certain rights and
protections under ERISA, which provides that all Plan participants shall be entitled to: 
 (i) Examine without
charge, at the Administrator’s office and at other specified locations such as worksites, all Plan documents, and copies of all documents filed by the Plan with the U.S. Department of Labor, such as detailed annual reports. 

(ii) Obtain copies of all Plan documents and other Plan information upon written request to the Administrator. The
Administrator may make a reasonable charge for the copies. 
 (iii) To the extent applicable, receive a summary
of the Plan’s annual financial report. The Administrator is required by law to furnish each participant with a copy of this summary annual report. 
 In addition to creating rights for Plan participants, ERISA imposes obligations upon the people who are responsible for the operation of employee benefit plans. The people who operate the Plan, called
“fiduciaries” of the Plan, have a duty to do so prudently and in the interest of Participants and beneficiaries. No one, including the Company, may fire a Participant or otherwise discriminate against the Participant in any way to prevent
the Participant from obtaining benefits or exercising his or her rights under ERISA. 
 If a claim for a benefit under this Plan is denied in
whole or in part, a Participant has the right to know why this was done, to obtain copies of documents relating to the decision without charge, and to appeal any denial, all within certain time schedules. 

Under ERISA, there are steps a Participant can take to enforce the above rights. For instance, if a Participant requests materials from the Administrator
and does not receive them within 30 days, the Participant may file suit in a federal court. In such a case, the court may require the Administrator to provide the materials and pay the Participant up to $110 a day until the Participant receives the
materials, unless the materials were not sent because of reasons beyond the control of the Administrator. If a Participant’s claim for benefits is denied or ignored, in whole or in part, the Participant may file suit in a state or federal
court. If a Participant is discriminated against for asserting his or her rights, the Participant may seek assistance from the U.S. Department of Labor, or file suit in a federal court. The court will decide who should pay court costs and legal
fees. If the Participant is successful, the court may order the person sued by the Participant to pay the costs and fees. If the Participant loses, the court may order the Participant to pay the costs and fees (for example, if it finds that the
Participant’s claim is frivolous). 

  
 10 

 If a Participant has any questions about this Plan, the Participant should contact the Administrator. If a
Participant has any questions about this statement or about his or her rights under ERISA, or if a Participant needs assistance in obtaining documents from the Administrator, he or she should contact the nearest office of the Employee Benefits
Security Administration, U.S. Department of Labor, listed in the telephone directory or the Division of Technical Assistance and Inquiries, Employee Benefits Security Administration, U.S. Department of Labor, 200 Constitution Avenue N.W., Washington
D.C. 20210. A Participant may also obtain certain publications about his or her rights and responsibilities under ERISA by calling the publications hotline of the Employee Benefits Security Administration.

to the terms of the Plan, the transactions contemplated by the Purchase Agreement (the “Transaction”) will not constitute a “Change in Control” (as defined in the Plan). 

D. Notwithstanding the fact that the Transaction will not constitute a “Change in Control”, as permitted by the terms of the
Plan, the General Partner wishes to provide for certain additional vesting rights of the Restricted Units in connection with, and subject to the occurrence of, the Closing (as defined in the Purchase Agreement). 

E. The Award Agreements may be amended by a written instrument signed by both Holder and the General Partner. 

AGREEMENT: 
 In
consideration of the mutual premises and covenants contained herein, the General Partner and Holder agree to amend the Award Agreement as follows: 
  

	 	1.	 Notwithstanding any provision to the contrary in the Award Agreements, the Restricted Units held by Holder subject to each applicable Award Agreement
that remain subject to a Restricted Period (as defined in the applicable Award Agreement) 

 
as of the date hereof shall vest on the earlier to occur of
            1 (the “Early Vesting Date”) and the “Vesting Date” (as defined in the applicable Award Agreement), provided that Holder has been continuously employed by the Employer (as
defined in the Plan) from the Closing through such date and such Restricted Units have not otherwise been forfeited in accordance with the terms of the Plan and the applicable Award Agreement prior to such date. 

 

	 	2.	Notwithstanding the foregoing, if, prior to the Early Vesting Date or the Vesting Date (as applicable) Holder’s employment with the Employer is terminated by the
Employer without “Cause” (as defined in the Plan) or Holder’s death or disability (as determined pursuant to the long-term disability plans maintained by the Company and its Affiliates from time to time) or Holder resigns his or her
employment with the Employer following the occurrence of a “Constructive Termination Event” (as hereinafter defined), all such Restricted Units shall vest as of the date of such termination. 

 

	 	3.	For purposes of Section 2 of this Amendment, a “Constructive Termination Event” means the occurrence, without Holder’s written consent of:
(a) a material reduction in Holder’s annual base salary [or the annual target bonus opportunity established under Holder’s employment agreement with the Company or one of its Affiliates]; (b) the Employer requiring a relocation
of the Holder’s principal place of employment more than 50 miles from Holder’s principal place of employment as of the Closing; (c) [any material breach by the Employer of a material provision of Holder’s written employment
agreement with the Employer; or (d)] a material diminution in Holder’s duties or responsibilities; provided, however, that Holder gives written notice to the Employer of the existence of such a condition within 90 days of the initial existence
of the condition, the General Partner has at least 30 days from the date when such notice is provided to cure the condition (if such condition can be cured) without being required to provide vesting due to termination of employment, and Holder
actually terminates Holder’s employment due to the Constructive Termination Event within six months of the initial occurrence of any of the conditions above. 

 

	 	4.	Holder expressly acknowledges and agrees that the Transaction will not constitute a “Change in Control” under the terms of the Plan and that the vesting
provided for pursuant to Sections 1 and 2 of this Amendment is the only additional vesting that Holder is entitled to in connection with the Transaction. 

  

	 	5.	Notwithstanding anything herein to the contrary, this Amendment shall be effective and contingent upon the Closing. Should the Purchase Agreement be terminated pursuant
to its terms without the occurrence of the Closing, this Amendment shall be null and void ab initio. Except as expressly set forth herein, the Award Agreement shall remain in full force and effect. 

 

	1 	December 31, 2013 for certain corporate center employees and the first anniversary of the Closing for all other employees. 

  
 2 

	 	6.	This Amendment and the Award Agreements contain the entire understanding of the parties with respect to the subject matter hereof and thereof. There are no
restrictions, agreements, promises, representations, warranties, covenants or undertakings with respect to the subject matter hereof other than those expressly set forth herein and therein. This Amendment supersedes all prior agreements and
understandings between the parties with respect to such subject matter. 

  

	 	7.	This Amendment shall be governed by and construed in accordance with the laws of the State of Delaware, excluding its conflict of laws provisions.

  

	 	8.	This Amendment may be executed in one or more counterparts, each of which will be deemed to be an original but all of which together will constitute one in the same
instrument.
