		Re:	The Waste Connections US, Inc. Separation Benefits Plan

 

Dear Mary Anne:

 

This letter agreement (this “Letter
Agreement”) relates to the Separation Benefits Plan (and Summary Plan Description) of Waste Connections US, Inc.,
a Delaware corporation (the “Company”), effective July 24, 2018 (the “Plan”).

 

Through this Letter Agreement, you are
being offered the opportunity to become a participant in the Plan (a “Participant”), and thereby to be
eligible to receive the severance and change in control benefits set forth therein, effective as of October 19, 2018 (the “Participant
Effective Date”). A copy of the Plan is attached to this Letter Agreement. You should read it carefully and become
comfortable with its terms and conditions, and those set forth below.

 

By signing below, you will be acknowledging and agreeing to
the following provisions:

 

		1.	that you have received and reviewed a copy of the Plan;

 

		2.	that terms not defined in this Letter Agreement but beginning with a capital letter have the meaning
assigned to them in the Plan;

 

		3.	that participation in the Plan requires that you agree irrevocably and voluntarily to the terms
of the Plan (including, without limitation, the covenants set forth in Sections 5, 6 and 12 of the Plan) and the terms set forth
below; and

 

		4.	that you have had the opportunity to carefully evaluate this opportunity, and desire to participate
in the Plan according to the terms and conditions set forth herein.

 

     

     

    

 

Subject to the foregoing, we invite you
to become a Participant in the Plan. Your participation in the Plan will be effective upon your signing and returning this Letter
Agreement to the Company within thirty (30) days of your receipt of this Letter Agreement.

 

You and the Company (hereinafter referred
to as the “parties”) hereby AGREE as follows:

 

		1.	Positions and Responsibilities. During the Term, you will be directly employed by the Company,
will serve as Senior Vice President and Chief Financial Officer of Waste Connections, Inc., a corporation organized under the laws
of Ontario, Canada (the “Parent”) and certain of its subsidiaries, including the Company, and will perform
such other duties and responsibilities as may be reasonably assigned to you from time to time by the Parent’s Board of Directors
(the “Board”), Chief Executive Officer (the “CEO”) and/or President. You will
devote your attention, energies and abilities in those capacities to the proper oversight and operation of the business of the
WCI Group to the exclusion of any other occupation. As Senior Vice President and Chief Financial Officer of the Parent and certain
of its subsidiaries, including the Company, you will: (i) report to the CEO or his designee, (ii) be based at the Parent’s
principal administrative offices in The Woodlands, Texas, and (iii) be responsible for all duties, authority and responsibility
customary for such positions. You will devote such time and attention to your duties as are reasonably necessary to the proper
discharge of your responsibilities hereunder. You agree to perform all duties consistent with: (a) policies established from time
to time by the WCI Group; and (b) all applicable legal requirements. For purposes of the Plan, you are hereby designated as an
SVP Participant.

 

		2.	Compensation, Benefits and Reimbursement of Expenses.

 

		a.	Base Salary. The Company hereby agrees to pay you an annual base salary of Four Hundred
Thousand Dollars ($400,000) (“Base Salary”). Your Base Salary will be payable in accordance with the
Company’s normal payroll practices, and your Base Salary is subject to withholding and social security, unemployment and
other taxes. Further increases in Base Salary will be considered by the Board.

 

		b.	Performance Bonus. You shall be entitled to an annual cash bonus (the “Bonus”)
based on the Parent’s attainment of reasonable financial objectives to be determined annually by the Board. Your target annual
Bonus will equal Fifty Percent (50%) of the applicable year’s ending Base Salary and will be payable if the Board determines,
in its sole and exclusive discretion, that that year’s financial objectives have been fully met. Nothing in the Plan or in
this Letter Agreement shall invalidate any cash bonus plan approval by the Board or a Committee of the Board providing for higher
payments in the event extraordinary or “stretch” goals are met. The Bonus will be paid in accordance with the Parent’s
bonus plan, as approved by the Board; provided, that in no case shall any portion of the Bonus with respect to any such fiscal
year be paid more than three (3) months after the end of such fiscal year.

 

     

     

    

 

		c.	Grants of Equity Awards. You shall be eligible for annual grants of restricted share unit
awards, performance share unit awards or other Equity Awards on such terms and to such level of participation as the Board or the
Compensation Committee of the Board determines to be appropriate, bearing in mind your positions and responsibilities. The terms
of any such Equity Awards shall be governed by the relevant plans under which they are issued and described in detail in applicable
agreements between the Parent and you.

 

		d.	Other Benefits. You will be entitled to paid annual vacation, which will accrue on the same
basis as for other employees of the Company of similar rank, but which will in no event be less than four (4) weeks for any twelve
(12) month period commencing January 1st of each year. You also will be entitled to participate, on the same terms as other employees
of the Company participate, in any medical, dental or other health plan, pension plan, profit-sharing plan and life insurance plan
that the Company may adopt or maintain, any of which may be changed, terminated or eliminated by the Company at any time in its
exclusive discretion.

 

		e.	Reimbursement of Other Expenses. The Company agrees to pay or reimburse you for all reasonable
travel and other expenses incurred by you in connection with the performance of your duties on presentation of proper expense statements
or vouchers. All such supporting information shall comply with all applicable Company policies relating to reimbursement for travel
and other expenses.

 

		3.	Change in Control. For purposes of this Letter Agreement, in addition to the events described
in the definition of “Change in Control” in Section 27(f) of the Plan, a Change in Control shall also occur if:

 

		a.	any “person” (as defined in Section 13(d) and 14(d) of the Exchange Act), shall become
the “beneficial owner” (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of fifty percent
(50%) or more of the outstanding voting securities of a subsidiary of Parent that owns all or substantially all of the WCI Group’s
United States operations;

 

		b.	there is a reorganization, merger or other business combination of a subsidiary of Parent that
owns all or substantially all of the WCI Group’s United States operations with any other corporation, other than any such
merger or other combination that would result in the voting securities of the subsidiary outstanding immediately prior thereto
continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity)
at least fifty percent (50%) of the total voting power represented by the voting securities of the subsidiary or such surviving
entity outstanding immediately after such transaction; or

 

     

     

    

 

		c.	there is a direct or indirect sale, lease, exchange or other transfer (in one transaction or a
series of related transactions) by the WCI Group of all, or substantially all, of its United States operations.

 

		4.	Right to Other Payments. In consideration of becoming eligible to receive the severance
and change in control benefits provided under the terms and conditions of the Plan, in addition to providing the waiver required
by Section 7(e) or Section 8(c) of the Plan, as applicable, you agree to waive any and all rights, benefits, and privileges to
severance benefits that you might otherwise be entitled to receive under any other plan or arrangement.

 

		5.	Entire Agreement. You understand that the waiver set forth in Section 4 above is irrevocable
and that this Letter Agreement and the Plan set forth the entire agreement between the parties with respect to any subject matter
covered herein. You agree and acknowledge that this Letter Agreement and the Plan supersede and replace that certain letter agreement
between you and the Company, dated August 30, 2018.

 

		6.	Survival. Your participation in the Plan will continue in effect following any termination
that occurs while you are a Participant in the Plan with respect to all rights and obligations accruing as a result of such termination.

 

		7.	Counterparts. This Letter Agreement may be executed in any number of counterparts, each
of which shall be enforceable against the parties actually executing such counterparts, and all of which together shall constitute
one instrument. A facsimile, telecopy or other reproduction of this Letter Agreement may be executed by one or more parties and
delivered by such party by facsimile or any similar electronic transmission device pursuant to which the signature of or on behalf
of each such party can be seen. Such execution and delivery shall be considered valid, binding and effective for all purposes.

 

		8.	Miscellaneous. This Letter Agreement and the Plan set forth the entire agreement between
the WCI Group and you concerning the subject matter described herein, and fully supersede any and all prior oral or written agreements,
promises or understandings between the WCI Group and you concerning the subject matter described herein including, without limitation,
any acceleration provisions set forth in any agreement evidencing an Equity Award held by you. Further, you represent and acknowledge
that in executing this Letter Agreement, you do not rely, and have not relied, on any prior oral or written communications by the
WCI Group, and you expressly disclaim any reliance on any prior oral or written communications, agreements, promises, inducements,
understandings, statements or representations in entering into this Letter Agreement. Therefore, you understand that you are precluded
from bringing any fraud or fraudulent inducement claim against the WCI Group associated with any such communications, agreements,
promises, inducements, understandings, statements or representations. The Company and you are entering into this Letter Agreement
based on each party’s own judgment.

 

     

     

    

 

		9.	Execution. You recognize and agree that your execution of this Letter Agreement results
in your enrollment and participation in the Plan, that you agree to be bound by the terms and conditions of the Plan and this Letter
Agreement, and that you understand that this Letter Agreement may not be amended or modified except pursuant to Section 20 of the

and

 

WHEREAS, the
Company recently amended that certain Separation Benefits Plan (and Summary Plan Description), effective July 24, 2018, under which

WHEREAS, the
Company and the Executive have determined that it is prudent to amend the Plan to make corresponding changes to the Plan’s
terms and conditions by executing this Amendment.

 

NOW, THEREFORE,
for good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the Parties hereby agree as follows:

 

1.       Retention
Award. The first sentence of Section 4(g) of the Plan is hereby amended by deleting the phrase “In consideration of the
Executive’s entering into this Amendment” and replacing it with the phrase “In consideration of the Executive’s
entering into the Second Amendment to this Plan, dated February 13, 2018,”.

 

2.       Termination
for Cause. Section 7(a) of the Plan is hereby amended by revising the definition of “Cause,” to be and to read
as follows:

 

“For purposes of this Plan,
“Cause” shall mean:

 

1.       gross
negligence or willful misconduct of a material nature in connection with the performance of the Executive’s duties;

 

2.       the
Executive’s conviction of (or pleading guilty or pleading no contest or nolo contendere to) a felony;

 

3.       a
non-de minimis intentional act of dishonesty or misappropriation (or attempted misappropriation) of property belonging to
the Company and/or any member of the WCI Group (other than a good faith expense account dispute related to a business expense);

 

    	 	 	 

     

    

 

4.       a
material breach by the Executive of any of the obligations under this Plan or any other agreement with the Company or any member
of the WCI Group or any policy of the WCI Group that is not immediately corrected following written notice of default specifying
such breach; or

 

5.       a
breach (material or otherwise) of any of the provisions of Sections 5, 6 or 12 of this Plan.

 

“WCI Group”
means, for purposes of this Plan, the Parent, the Company and each of their subsidiaries and affiliates.”

 

3.       Termination
without Cause. Section 7(b) of the Plan is hereby deleted and replaced in its entirety with the following:

 

“The employment of the Executive
may be terminated without Cause at any time by the vote of a majority of the Board on delivery to the Executive of a written Notice
of Termination (as defined in Section 9(a)). On a termination of Executive’s employment without Cause, the Company shall
pay to the Executive in lieu of payments under Sections 4(a), 4(b) and 4(d) for the remainder of the Term, Seven Million Five Hundred
Thousand Dollars ($7,500,000) in a lump sum payment on or within 60 days following the Date of Termination; provided, however,
that if the 60-day period begins in one calendar year and ends in the subsequent calendar year, such payment shall be made in the
latter calendar year. Notwithstanding anything in this Plan or this Section to the contrary, all actions under this Plan shall
be completed in a manner that complies with or is exempt from Section 409A of the Internal Revenue Code of 1986, as amended (the
“Code”). In addition, for three years following the Executive’s termination of employment, the Company shall
make available to the Executive and the Executive’s eligible dependents coverage under the Company’s group medical
insurance (including group health, dental, and visions benefits) (which shall be concurrent with any health care continuation benefits
to which the Executive or his eligible dependents are entitled under Consolidated Omnibus Budget Reconciliation Act (“COBRA”);
provided, however, that the Executive shall be obligated to pay the Company for the portion of the premiums for such coverage on
an after-tax basis equal to the amount paid by active employees for such coverage (the “Health Insurance Benefit”).
Notwithstanding the previous sentence, with regard to such continuation coverage, if the Company determines in its sole discretion
that it cannot provide the foregoing benefit without potentially violating applicable law or potentially incurring penalties, excise
taxes and fees pursuant to the Internal Revenue Code and the Department of Treasury regulations promulgated thereunder (including,
without limitation, Section 2716 of the Public Health Service Act), the Health Insurance Benefit shall terminate and the Executive
shall not be eligible to receive any further benefits related to the Health Insurance Benefit other than as otherwise required
by applicable law. In addition, on termination of the Executive under this Section 7(b), all of the Executive’s outstanding
but unvested time-based equity awards shall immediately vest and become exercisable and all restrictions thereon shall lapse, as
applicable. With respect to the Executive’s outstanding but unvested equity awards that vest or become earned based on the
achievement of pre-established performance goals or criteria over a specified time period, the designated performance goals for
such awards shall be deemed to have been satisfied (and, for any award with different levels of potential payment, such performance
shall be deemed to be at the target level) and any remaining vesting conditions shall be deemed to be satisfied on the Executive’s
Date of Termination and such equity awards shall be settled as soon as administratively practicable thereafter. The term of any
stock options shall be extended to the earlier of (i) the fifth anniversary of the Executive’s termination or (ii) the expiration
of the original term of such stock options. The Executive acknowledges that extending the term of any incentive stock option pursuant
to this Section could cause such stock option to lose its tax-qualified status under the Code, and agrees that the Company shall
have no obligation to compensate the Executive for any additional taxes he incurs as a result.

 

    	 	2	 

     

    

 

In the event that the Executive’s
employment is terminated pursuant to this Section 7(b), on or prior to the 90th day following the Date of Termination, the Board
shall elect whether to apply the Optional Restricted Period. If the Board elects to apply the Optional Restricted Period, then
in addition to the payments and benefits described in the preceding paragraph of this Section 7(b), Company shall pay to the Executive
the amounts as set forth in the last paragraph of Section 7(a) hereof relating to the election of the Optional Restricted Period
at the times and subject to the conditions set forth therein.”

 

4.       Termination
on Disability. Section 7(c) of the Plan is hereby deleted and replaced in its entirety with the following:

 

“If during the Term the Executive
should fail to perform his duties hereunder on account of physical or mental illness or other incapacity which the Board shall
in good faith determine renders the Executive incapable of performing his duties hereunder, and such illness or other incapacity
shall continue for a period of more than six (6) consecutive months (“Disability”), the Company shall have the right,
on written Notice of Termination (as defined in Section 9(a)) delivered to the Executive to terminate the Executive’s employment
under this Plan. During the period that the Executive shall have been incapacitated due to Disability, the Executive shall continue
to receive the full Base Salary provided for in Section 4(a) hereof at the rate then in effect until the Date of Termination (as
defined in Section 9(b)) pursuant to this Section 7(c). If the Executive’s employment is terminated due to Disability during
the Term, the Executive shall be entitled to receive, and the Company agrees to pay and deliver, the payments and other benefits
applicable to termination without Cause set forth in Section 7(b) hereof at the times and subject to the conditions set forth therein.
In addition, on termination of the Executive under this Section 7(c), all of the Executive’s outstanding but unvested time-based
equity awards shall immediately vest and become exercisable and all restrictions thereon shall lapse, as applicable. With respect
to the Executive’s outstanding but unvested equity awards that vest or become earned based on the achievement of pre-established
performance goals or criteria over a specified time period, the designated performance goals for such awards shall be deemed to
have been satisfied (and, for any award with different levels of potential payment, such performance shall be deemed to be at the
target level) and any remaining vesting conditions shall be deemed to be satisfied on the Executive’s Date of Termination
and such equity awards shall be settled as soon as administratively practicable thereafter. The term of any stock options shall
be extended to the earlier of (i) the fifth anniversary of the Executive’s termination or (ii) the expiration of the original
term of such stock options. The Executive acknowledges that extending the term of any incentive stock option pursuant to this Section
could cause such stock option to lose its tax-qualified status under the Code, and agrees that the Company shall have no obligation
to compensate the Executive for any additional taxes he incurs as a result.

In the event that the Executive’s
employment is terminated pursuant to this Section 7(c), on or prior to the 90th day following the Date of Termination, the Board
shall elect whether to apply the Optional Restricted Period. If the Board elects to apply the Optional Restricted Period, then
in addition to the payments and benefits described in the preceding paragraph of this Section 7(c), the Company shall pay to the
Executive the amounts as set forth in the last paragraph of Section 7(a) hereof relating to the election of the Optional Restricted
Period at the times and subject to the conditions set forth therein.”

 

5.       Death.
Section 7(d) of the Plan is hereby deleted and replaced in its entirety with the following:

 

“If the Executive dies during
the Term the Company shall pay to the Executive’s estate the payments and other benefits applicable to termination without
Cause set forth in Section 7(b) hereof. Any cash payments shall be paid in a lump sum on or within 60 days following the date of
death; provided, however, that if the 60-day period begins in one calendar year and ends in the subsequent calendar year, such
payment shall be made in the latter calendar year. In addition, on termination of the Executive under this Section 7(d), all of
the Executive’s outstanding but unvested time-based equity awards shall immediately vest and become exercisable and all restrictions
thereon shall lapse, as applicable. With respect to the Executive’s outstanding but unvested equity awards that vest or become
earned based on the achievement of pre-established performance goals or criteria over a specified time period, the designated performance
goals for such awards shall be deemed to have been satisfied (and, for any award with different levels of potential payment, such
performance shall be deemed to be at the target level) and any remaining vesting conditions shall be deemed to be satisfied on
the Executive’s Date of Termination and such equity awards shall be settled as soon as administratively practicable thereafter.
The term of any stock options shall be extended to the earlier of (i) the fifth anniversary of the Executive’s termination
or (ii) the expiration of the original term of such stock options. The Executive acknowledges that extending the term of any incentive
stock option pursuant to this Section could cause such stock option to lose its tax-qualified status under the Code, and agrees
that the Company shall have no obligation to compensate the Executive for any additional taxes he incurs as a result. The provisions
of this Section 7(d) shall not affect the entitlements of the Executive’s heirs, executors, administrators, legatees, beneficiaries
or assigns under any employee benefit plan, fund or program of the Company.”

 

    	 	4	 

     

    

 

6.       Termination
for Good Reason. The first paragraph of Section 8(a) of the Plan is hereby deleted and replaced in its entirety with the following:

 

“In the event the Executive
terminates his employment with the Company for Good Reason (as defined below), the Executive shall be entitled to receive, and
the Company agrees to pay and deliver, the payments and other benefits applicable to termination without Cause set forth in Section
7(b) hereof at the times and subject to the conditions set forth therein. In addition, on termination of the Executive under this
Section 8(a), all of the Executive’s outstanding but unvested time-based equity awards shall immediately vest and become
exercisable and all restrictions thereon shall lapse, as applicable. With respect to the Executive’s outstanding but unvested
equity awards that vest or become earned based on the achievement of pre-established performance goals or criteria over a specified
time period, the designated performance goals for such awards shall be deemed to have been satisfied (and, for any award with different
levels of potential payment, such performance shall be deemed to be at the target level) and any remaining vesting conditions shall
be deemed to be satisfied on the Executive’s Date of Termination and such equity awards shall be settled as soon as administratively
practicable thereafter. The term of any stock options shall be extended to the earlier of (i) the fifth anniversary of the Executive’s
termination or (ii) the expiration of the original term of such stock options. The Executive acknowledges that extending the term
of any incentive stock option pursuant to this Section could cause such stock option to lose its tax-qualified status under the
Code, and agrees that the Company shall have no obligation to compensate the Executive for any additional taxes he incurs as a
result.”

 

7.       Definitions.
Section 10(b) of the Plan is hereby deleted and replaced in its entirety with the following:

Plan, a Change in Control shall be deemed to have occurred if:

 

		1.	there shall be consummated (i) any reorganization, liquidation or consolidation of Parent, or any
merger or other business combination of Parent with any other corporation, other than any such merger or other combination that
would result in the voting securities of Parent outstanding immediately prior thereto continuing to represent (either by remaining
outstanding or by being converted into voting securities of the surviving entity) at least fifty percent (50%) of the total voting
power represented by the voting securities of Parent or such surviving entity outstanding immediately after such transaction, or

13d-3 under the Exchange Act), directly or indirectly, of fifty percent (50%) or more of the Parent’s outstanding voting
securities; or

 

		3.	during any period of two consecutive years, individuals who at the beginning of such period constituted

nomination for election by Parent’s shareholders, of each new director was approved by a vote of at least one-half of the
directors then still in office who were directors at the beginning of the period.

 

No benefits deemed non-qualified
deferred compensation subject to Section 409A shall be payable upon a Change in Control pursuant to this Plan unless such Change

Other Changes. Except as provided in this Amendment, the Plan shall remain in full force and effect and remain unchanged.

14.       Governing
Law. The Plan and this Amendment are together intended to be a Top Hat Plan and shall be interpreted, administered and enforced

presented to the Plan Administrator in writing. Within ninety (90) days after receiving a claim, a claims official appointed by
the Plan Administrator shall consider the claim and issue his or her determination thereon in writing. If the Plan Administrator
or claims official determines that an extension of time is necessary, the claims official may extend the determination period for
up to an additional ninety (90) days by giving the Executive written notice indicating the special circumstances requiring the
extension of time prior to the termination of the initial ninety (90) day period. Any claims that the Executive does not pursue
in good faith through the initial claims stage shall be treated as having been irrevocably waived.

 

Claims Decisions

 

If the claim is granted,
the benefits or relief the Executive seeks shall be provided. If the claim is wholly or partially denied, the claims official shall,
within ninety (90) days (or a longer period, as described above), provide the Executive with written notice of the denial, setting
forth, in a manner calculated to be understood by the Executive: (1) the specific reason or reasons for the denial; (2) specific
references to the provisions on which the denial is based; (3) a description of any additional material or information necessary
for the Executive to perfect the claim, together with an explanation of why the material or information is necessary; and (4) an
explanation of the procedures for appealing denied claims. If the Executive can establish that the claims official has failed to
respond to the claim in a timely manner, the Executive may treat the claim as having been denied by the claims official.

 

Appeals of Denied
Claims

 

The Executive shall
have the opportunity to appeal the claims official’s denial of a claim in writing to an appeals official appointed by the
Plan Administrator (which may be a person, committee, or other entity). The Executive must appeal a denied claim within sixty (60)
days after receipt of written notice of denial of the claim, or within sixty (60) days after it was due if the Executive did not
receive it by its due date. The Executive shall have the opportunity to submit written comments, documents, records and other information
relating to the Executive’s claim. The Executive (or the Executive’s duly authorized representative) shall be provided
upon request and free of charge, reasonable access to, and copies of, all documents, records and other information relevant to
the Executive’s claim. The appeals official shall take into account during its review all comments, documents, records and
other information submitted by the Executive relating to the claim, without regard to whether such information was submitted or
considered in the initial benefits review. Any claims that the Executive does not pursue in good faith through the appeals stage,
such as by failing to file a timely appeal request, shall be treated as having been irrevocably waived.

 

    	 	
Appendix A-1	 

     

    

 

Appeals Decisions

 

The decision by the
appeals official shall be made not later than sixty (60) days after the written appeal is received by the Plan Administrator, however,
if the appeals official determines that an extension of time is necessary, the appeals official may extend the determination period
for up to an additional sixty (60) days by giving the Executive written notice indicating the special circumstances requiring the
extension of time prior to the termination of the initial sixty (60) day period. The appeal decision shall be in writing, shall
be set forth in a manner calculated to be understood by the Executive and shall include the following: (1) the specific reason
or reasons for the denial; (2) specific references to the provisions on which the denial is based; (3) a statement that the Executive
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 Executive’s claim. If the Executive does not receive the appeal decision by the date it is due,
the Executive may deem the appeal to have been denied.

 

Procedures

 

The Plan Administrator
shall adopt procedures by which initial claims shall be considered and appeals shall be resolved; different procedures may be established
for different claims. All procedures shall be designed to afford the Executive full and fair consideration of his or her claim.

 

Additional Disability
Claims Procedures

 

Notwithstanding anything to the contrary above, disability claims
and appeals under this Plan shall comply with the following requirements (in addition to any requirements above):

 

Initial Claims

 

Within forty-five (45) days after receiving
a claim, a claims official appointed by the Plan Administrator shall consider the claim and issue his or her determination thereon
in writing. If the Plan Administrator or claims official determines that an extension of time is necessary, the claims official
may extend the determination period twice by thirty (30) days by giving the Executive prior written notice indicating the special
circumstances requiring the extension of time and the date by which we expect to render a decision. If such an extension is necessary
due to the Executive’s failure to submit the information necessary to decide the claim, the notice of extension will specifically
describe the required information, and the Executive will be afforded at least forty-five (45) days within which to provide the
specified information. If the Executive delivers the requested information within the time specified, any thirty (30)-day extension
period will begin after the Executive has provided that information.

 

Appeals

 

The Executive must
appeal a denied claim within one hundred eighty (180) days after receipt of written notice of denial of the claim. The decision
by the appeals official shall be made not later than forty-five (45) days after the written appeal is received by the Plan Administrator,
however, if the appeals official determines that an extension of time is necessary, the appeals official may extend the determination
period for up to an additional forty-five (45) days by giving the Executive written notice indicating the special circumstances
requiring the extension of time prior to the termination of the initial forty-five (45) day period. If an extension is necessary
due to the Executive’s failure to submit the information necessary to decide the appeal, the notice of extension will specifically
describe the required information, and the Executive will be afforded at least forty-five (45) days to provide the specified information.
If the Executive delivers the requested information within the time specified, the forty-five (45) day extension of the appeal
period will begin after the Executive has provided that information.

 

    	 	
Appendix A-2	 

     

    

 

Effective as of April
1, 2018, the following provisions apply with respect to a claim for disability benefits under this Plan. The claims requirements
above shall apply as the internal claims process except as provided under DOL Reg. 2650.503-1 and any superseding guidance.

 

(1)       Independent
and Impartial Review. The Plan must meet the conflict of interest requirements under DOL Reg. 2560.503-1(b)(7). All claims
and appeals for disability benefits must be adjudicated in a manner designed to ensure the independence and impartiality of the
persons involved in making the decision. Accordingly, decisions regarding hiring, compensation, termination, promotion, or other
similar matters with respect to any individual (such as a claims adjudicator or medical or vocational expert) must not be made
based upon the likelihood that the individual will support the denial of benefits.

 

(2)       Adverse
Benefit Determination. An adverse benefit determination also includes any rescission of coverage as described in DOL Reg. 2560.503-1(m)(4)(ii).

 

(3)       Full
and Fair Review. The Executive must be allowed to review the file and present evidence and testimony as part of the appeals
process. Executives must be provided, free of charge, with any new or additional evidence considered, relied upon or generated
by the Plan in connection with the claim sufficiently in advance of the final adverse benefit determination to give the Executive
a reasonable opportunity to respond prior to that date in accordance with DOL Reg. 2560.503-1(h)(4).

 

(4)       Deemed
Exhaustion of Claims Process. If the Plan fails to adhere to the requirements of DOL Reg. 2560.503-1, except as provided under
DOL Reg. 2560.503-1(l)(2)(ii), the Executive may bring an action under section 502(a) of ERISA as provided in DOL Reg. 2560.503-1(l)(2)(i)
and any superseding guidance.

 

(5)       Notices.
A notice of adverse benefit determination must include the information required under DOL Reg. 2560.503-1(g)(vii), (j)(4) and (j)(6),
as applicable. The notice of adverse benefit determination must include a discussion of the decision, including an explanation
of the basis for disagreeing with or not following:

 

(A)   The views
presented by the Executive to the Plan of health care professionals treating the Executive and vocational professionals who evaluated
the Executive;

 

(B)   The views
of medical or vocational experts whose advice was obtained on behalf of the plan in connection with the Executive’s adverse
benefit determination, without regard to whether the advice was relied upon in making the benefit determination; and

 

    	 	
Appendix A-3	 

     

    

 

(C)   A disability
determination regarding the Executive presented by the Executive to the Plan made by the Social Security Administration;

 

If the adverse benefit
determination is based on a medical necessity or experimental treatment or similar exclusion or limit, the notice should contain
an explanation of the scientific or clinical judgment for the determination, applying the terms of the Plan to the Executive’s
medical circumstances, or a statement that such explanation will be provided free of change upon request. In addition, if any specific
internal rules, guidelines, protocols, standards or other similar criteria of the plan were relied upon in making the adverse determination,
the notice should describe such criteria or, alternatively, a statement that such rules, guidelines, protocols, standards or other
similar criteria of the plan do not exist.

 

The notice must be
provided in a culturally and linguistically appropriate manner as provided under DOL Reg. 2560.503-1(g)(viii), (j)(7), and (o).
If the Plan maintains a contractual deadline to file a civil action under section 502(a) of ERISA, the notice of adverse benefit
determination shall disclose the specific deadline, including the calendar date on which the Executive’s rights expire, as
required by DOL Reg. 2560.503-1(j)(4)(ii).

 

Arbitration of Rejected
Appeals

 

If the Executive has
pursued a claim through the appeal stage of these claims procedures, the Executive may contest the actual or deemed denial of that
claim through arbitration, as described below. In no event shall any denied claim be subject to resolution by any means (such as
in a court of law) other than arbitration in accordance with the following provisions.

 

2.       Arbitration
Procedure

 

Request for Arbitration

 

The Executive must
submit a request for arbitration to the Plan Administrator within 60 days after receipt of the written denial of an appeal (or
within sixty (60) days after he or she should have received the determination). The Executive or the Plan Administrator may bring
an action in any court of appropriate jurisdiction to compel arbitration in accordance with these procedures.

 

Applicable Arbitration
Rules

 

If the Executive has
entered into a separate and valid arbitration agreement with the Company, the arbitration shall be conducted in accordance with
that agreement. If not, the rules set forth in the balance of this Appendix shall apply: The arbitration shall be held under the
auspices of the American Arbitration Association (“AAA”). Except as provided below, the arbitration shall be in accordance
with AAA’s then-current employment dispute resolution rules. The Arbitrator shall apply the Federal Rules of Evidence and
shall have the authority to entertain a motion to dismiss or a motion for summary judgment by any party and shall apply the standards
governing such motions under the Federal Rules of Civil Procedure. The Federal Arbitration Act shall govern all arbitrations that
take place under these Detailed Claims and Arbitration Procedures (or that are required to take place under them), and shall govern
the interpretation or enforcement of these Procedures or any arbitration award. To the extent that the Federal Arbitration Act
is inapplicable, Texas law pertaining to arbitration agreements shall apply.

 

    	 	
Appendix A-4	 

     

    

 

Arbitrator

 

The arbitrator (the
“Arbitrator”) shall be an attorney familiar with employee benefit matters who is licensed to practice law in the state
in which the arbitration is convened. The Arbitrator shall be selected in the following manner from a list of eleven arbitrators
drawn by the sponsoring organization under whose auspices the arbitration is being conducted and taken from its panel of labor
and employment arbitrators. Each party shall designate all arbitrators on the list whom they find acceptable; the parties shall
then alternately strike arbitrators from the list of arbitrators acceptable to both parties, with the party who did not initiate
the arbitration striking first. If only one arbitrator is acceptable to both parties, he or she will be the Arbitrator. If none
of the arbitrators is acceptable to both parties, a new panel of arbitrators shall be obtained from the sponsoring organization
and the selection process shall be repeated.

 

Location

 

The arbitration will
take place in or near the city in which the Executive is or was last employed by the Company or in which the Plan is principally
administered, whichever is specified by the Plan Administrator, or in such other location as may be acceptable to both the Executive
and the Plan Administrator.

 

Authority of Arbitrator

 

The Arbitrator shall
have the authority to resolve any factual or legal claim relating to the Plan or relating to the interpretation, applicability,
or enforceability of these arbitration procedures, including, but not limited to, any claim that these procedures are void or voidable.
The Arbitrator may grant the Executive’s claim only if the Arbitrator determines that it is justified because: (1) the appeals
official erred on an issue of law; or (2) the appeals official’s findings of fact, if applicable, were not supported by substantial
evidence. The arbitration shall be final and binding on all parties.

 

Limitation on Scope
of Arbitration

 

The Executive may not
present any evidence, facts, arguments, or theories at the arbitration that the Executive did not pursue in his or her appeal,
except in response to new evidence, facts, arguments, or theories presented on behalf of the other parties to the arbitration.
However, an arbitrator may permit the Executive to present additional evidence or theories if the Arbitrator determines that the
Executive was precluded from presenting them during the claim and appeal procedures due to procedural errors of the Plan Administrator
or its delegates.

 

Administrative Record

 

The Plan Administrator
shall submit to the Arbitrator a certified copy of the record on which the appeals official’s decision was made.

 

    	 	
Appendix A-5	 

     

    

 

Experts, Depositions,
and Discovery

 

Except as otherwise
permitted by the Arbitrator on a showing of substantial need, either party may: (1) designate one expert witness; (2) take the
deposition of one individual and the other party’s expert witness; (3) propound requests for production of documents; and
(4) subpoena witnesses and documents relating to the discovery permitted in this paragraph.

 

Pre-Hearing Procedures

 

At least thirty (30)
days before the arbitration hearing, the parties must exchange lists of witnesses, including any expert witnesses, and copies of
all exhibits intended to be used at the hearing. The Arbitrator shall have jurisdiction to hear and rule on pre-hearing disputes
and is authorized to hold pre-hearing conferences by telephone or in person, as the Arbitrator deems necessary.

 

Transcripts

 

Either party may arrange
for a court reporter to provide a stenographic record of the proceedings at the party’s own cost.

 

Post-Hearing Procedures

 

Either party, on request
at the close of the hearing, may be given leave to file a post-hearing brief within the time limits established by the Arbitrator.

 

Costs and Attorneys’
Fees

 

The prevailing party
shall be entitled to reasonable attorneys’ fees, costs and necessary disbursements in addition to any other relief to which
such party may be entitled, except as required by applicable law.

 

Procedure for Collecting
Costs From Executive

 

Before the arbitration
commences, the Executive must deposit with the Plan Administrator a payment equal to the amount of any fees that he or she would
pay to file a claim in court. The Company shall pay any portion of the anticipated fees and costs of the Arbitrator in excess of
that amount. In the event the Company is the prevailing party in any arbitration, the Arbitrator shall be permitted to reallocate
the fees and costs associated with the arbitration from the Company to the Participant and in such event the Participant shall
be obligated to reimburse the Company for such fees and costs within 10 days after such determination is made.

 

Arbitration Award

 

The Arbitrator shall
render an award and opinion in the form typically rendered in labor arbitrations. Within twenty (20) days after issuance of the
Arbitrator’s award and opinion, either party may file with the Arbitrator a motion to reconsider, which shall be accompanied
by a supporting brief. If such a motion is filed, the other party shall have twenty (20) days from the date of the motion to respond,
after which the Arbitrator shall reconsider the issues raised by the motion and either promptly confirm or promptly change his
or her decision. The decision shall then be final and conclusive on the parties. Arbitrator fees and other costs of a motion for
reconsideration shall be borne by the losing party, unless the Arbitrator orders otherwise. Either party may bring an action in
any court of appropriate jurisdiction to enforce an arbitration award. A party opposing enforcement of an arbitration award may
not do so in an enforcement proceeding, but must bring a separate action in a court of competent jurisdiction to set aside the
award. In any such action, the standard of review shall be the same as that applied by an appellate court reviewing the decision
of a trial court in a nonjury trial.

 

    	 	
Appendix A-6	 

     

    

 

Severability

 

The invalidity or unenforceability of any
part of these arbitration procedures shall not affect the validity of the rest of the procedures.
