 SCOPE
AND PARTICIPATION 
 3.1 Participation. Participants will be designated (pursuant to this Plan or as otherwise determined
by the Committee) as Tier 1 Participants, Tier 2 Participants, or Tier 3 Participants. 
 (a) Unless otherwise determined by
the Committee, an employee of the Company or any of its Subsidiaries will be a Participant in this Plan only if such employee is: 

(i) the Chief Executive Officer of the Company (the “Tier 1 Participant”), 

(ii) an Executive Vice President of the Company or a Subsidiary (a “Tier 2 Participant”), or 

(iii) a Vice President of the Company or a Subsidiary (a “Tier 3 Participant”). 

For purposes of determining the benefits (if any) to which a Participant is entitled under this Plan upon a termination of employment, the
Participant’s participation “Tier” will be determined as of the Participant’s Termination Date; provided, however, that if (x) a Participant’s change in “Tier” occurs as a result of a demotion
(without the Participant’s consent) that would give the Participant grounds for a termination of employment for Good Reason, (y) the Participant notifies the Company in writing of such Good Reason event within 90 days of its occurrence (or
the Participant’s employment is terminated by the Company within such 90-day period), and (z) the Participant’s Termination Date occurs within 300 days after the occurrence of such Good Reason
event, the Participant’s participation “Tier” will be determined as though such demotion had not occurred. 

(b) Unless otherwise expressly provided for in an Employment Agreement, each Participant is an
at-will employee whose employment may be terminated by the Participant or the Company at any time for any reason. In the event of a Change in Control, this Plan will govern the treatment of each
Participant’s Equity-Based Awards upon such Change in Control, unless the applicable Participant is party to an individual agreement with the Company that provides for treatment that is more favorable to the Participant. Upon the termination of
employment of a Participant, this Plan will govern the rights and responsibilities of the Company and the Participant with respect to the matters addressed by this Plan. No compensation or benefits will be payable to a Participant pursuant to
Section 4.2 unless the Participant experiences a Qualifying Termination. 

  
 8 

Effective December 9, 2022 












 (c) If a Participant has an Employment Agreement, then this Plan is intended
to provide certain protections to the Participant that are not afforded by the Employment Agreement; provided, however, that this Plan is not intended to provide benefits that are duplicative of a Participant’s Employment
Agreement (if any). 
 (d) Except as provided in Section 4.2 of this Plan, nothing in this Plan will prevent or limit a
Participant’s continuing or future participation in any plan, program, policy, or practice provided by the Company or any of its affiliated companies for which the Participant may qualify, nor will anything in this Plan limit or otherwise
affect any rights a Participant may have under any contract or agreement with the Company or any of its affiliated companies. Amounts that are vested benefits or which a Participant is otherwise entitled to receive under any plan, policy, practice,
or program of, or any contract or agreement with, the Company or any of its affiliated companies at or subsequent to the Termination Date will be payable in accordance with such plan, policy, practice, program, contract, or agreement unless
expressly superseded by this Plan. 
 ARTICLE IV 

TERMS AND CONDITIONS IN CONNECTION WITH A CHANGE IN CONTROL 

4.1 Treatment of Equity-Based Awards. Notwithstanding anything to the contrary in the Equity Compensation Plan, in the event of
a Change in Control, each Equity-Based Award held by a Participant that is outstanding and unvested on the date of such Change in Control is subject to the following: 

(a) If a Qualifying Replacement Award is provided to the Participant to continue, replace, or assume an outstanding and
unvested Equity-Based Award, the Qualifying Replacement Award will continue in effect in accordance with its terms, subject to Section 4.2 of this Plan. 

(b) If a Qualifying Replacement Award is not provided to the Participant to continue, replace, or assume an outstanding and
unvested Equity-Based Award, the Equity-Based Award will fully vest and (to the extent applicable) become exercisable immediately prior to (and contingent upon) the Change in Control; provided, however, that any such award that is a
Performance Award will vest at the Change in Control Performance Level. 
 4.2 Qualifying Termination in Connection with a Change
in Control. If a Participant experiences a Qualifying Termination, the Company will pay and provide to the Participant the amounts and benefits specified in this Section 4.2 subject to the Participant’s compliance with the terms of
this Plan (including Section 5.1), except that the Company will not be obligated to provide the compensation or benefits specified in Section 4.2(c) through Section 4.2(g) unless the Participant has timely executed (and not revoked) a
Release as contemplated by Section 4.3(b). The amounts and benefits specified in this Section 4.2 are as follows: 

(a) A lump sum amount in cash equal to the Participant’s Accrued Base Compensation. The Company will pay this amount to
the Participant within 30 days following the Termination Date and in accordance with applicable law. 

  
 9 

Effective December 9, 2022 












 (b) An amount equal to any STI Bonus the Participant earned for the calendar
year immediately preceding the calendar year in which the Termination Date occurs, to the extent not already paid. The Company will pay any such amount to the Participant on the same date (or dates) and in the same amount that such amount would have
been paid if the Participant’s employment had not been terminated. 
 (c) A lump sum amount in cash equal in value to
the product of (i) the Applicable CIC Multiplier multiplied by (ii) the sum of (A) the greater of the Participant’s annual Base Salary rate as of the Termination Date and the Participant’s Base Salary rate in effect
immediately prior to the Change in Control, plus (B) the Participant’s target STI Bonus for the calendar year in which the Termination Date occurs. Subject to Section 6.1, the Company will pay this amount to the Participant on the
Designated Date. 
 (d) A lump sum amount in cash equal in value to the Participant’s target STI Bonus for the calendar
year in which the termination of employment occurs, pro-rated based on the number of days that the Participant is employed by the Company during the applicable calendar year. Subject to Section 6.1, the
Company will pay this amount to the Participant on the Designated Date. 
 (e) For the period commencing on the Termination
Date and ending a number of years thereafter equal to the Participant’s Applicable CIC Multiplier, the Company will (at the Company’s expense) provide the Participant and the Participant’s covered dependents as of the
Participant’s Termination Date, medical, dental, and vision benefits substantially similar to those provided to the Participant and such covered dependents immediately prior to the Termination Date (such continuation of benefits referred to as
the “Welfare Benefit”). Any portion of the premium for such medical and health benefits that is paid by the Company will be treated as taxable to the Participant. Notwithstanding the foregoing, if a Participant’s
Termination Date occurs prior to a Change in Control and such Participant becomes entitled to benefits under this Plan upon the date of such Change in Control, the Company may pay to the Participant, in lieu of the benefits set forth above in this
subsection (e), a lump sum amount in cash equivalent to the portion of the premiums that would be paid by the Company pursuant to the provisions set forth above in this subsection (e), which amount will be paid to the Participant within 30 days
following the date of such Change in Control. 
 (f) Each Qualifying Replacement Award (if any) held by the Participant that
is outstanding and unvested as of the Termination Date will fully vest and (to the extent applicable) become exercisable upon the Participant’s termination of employment or, if later, upon the date of the Change in Control; provided,
however, that any award of stock options or stock appreciation rights described in this clause (f) will remain exercisable until the earlier of (x) the date that is 90 days after the later of the Termination Date and the date of the
Change in Control and (y) the date on which such award would have expired had the Participant remained continuously employed with the Company or a Subsidiary. Notwithstanding the foregoing, if a Participant’s Termination Date occurs prior
to a Change in Control and such Participant becomes entitled to benefits under this Plan upon the date of such Change in Control, the Company may pay to the Participant, in lieu of the benefits set forth above in this subsection (f), amounts in cash
equal to the fair market value (as reasonably determined by the Compensation Committee, as constituted immediately prior to the Change in Control) of the Qualifying Replacement Award(s) that would have otherwise vested pursuant to this subsection
(f), which amounts will be paid at a time or times consistent with the payment timing terms of the related Qualifying Replacement Award(s).

Effective December 9, 2022 












 (g) Reasonable executive outplacement services, for a period not to exceed
12 months after the later of the Termination Date or the date of the Change in Control, through a provider selected by the Company in its discretion. Such benefit will be taxable to the Participant. 

4.3 Release. This Section 4.3 will apply upon a Participant’s Qualifying Termination. 

(a) Presentation of Release by the Company. If this Section 4.3 applies, the Company will present to the
Participant, not later than 21 days after the later of the Termination Date or the date of the Change in Control, a Release with a covering message in which the Company advises the Participant that the Release is being presented in accordance with
this Section 4.3(a) and that a failure by the Participant to execute and return the Release as contemplated by Section 4.3(b) would relieve the Company of the obligation to make payments otherwise due to the Participant under one or more
portions of Section 4.2. 
 (b) Execution of Release by the Participant. The Participant will have until the
later of 60 days after the Termination Date or 30 days after the date of the Change in Control to deliver an executed copy of the Release to the Company and thereby satisfy the condition to receiving payments under any portion of Section 4.2,
provided that the Participant does not revoke the execution of the Release during any applicable revocation period. Notwithstanding anything in this Plan to the contrary, if a Participant’s Termination Date occurs prior to a Change in Control
and such Participant becomes entitled to benefits under this Plan upon the date of such Change in Control, any payment that would have otherwise been made to the Participant prior to the date that is 45 days after the Change in Control will instead
be paid to the Participant in a lump sum on the 45th day after the Change in Control. 

(c) Effect of Failure to Execute Release or of Revocation of Release. If the Participant fails to deliver an executed
copy of the Release to the Company within the time period prescribed in Section 4.3(b) or revokes the execution of the Release during any applicable revocation period, the Participant will be deemed to have waived the right to receive all
payments under Section 4.2 that were conditioned on the Release.

document, including any Employment Agreement, the Participant is obligated to abide by both such other restrictive covenants and the restrictive covenants set forth in this Plan, regardless of whether they are similar. 

(h) Survival of Covenants. Each covenant of the Participant set forth in this Section 5.1 will survive the
termination of the Participant’s employment. The existence of any claim or cause of action by the Participant against the Company, whether related to this Plan or otherwise, will not constitute a defense to the enforcement of the covenants in
this Section 5.1. In the event an enforcement remedy is necessary under this Section 5.1, the restricted time periods provided for in this Section 5.1 will commence on the date enforcement is ordered and complied with by the
Participant and will be extended by the period of noncompliance.

 (i) Acknowledgement. Nothing in this Plan or any ancillary agreement
prohibits the Participant from reporting, without prior notice to the Company, possible violations of law or regulation to any governmental agency or entity, otherwise testifying or participating in any investigation or proceeding by any
governmental authorities regarding possible legal violations, or making other disclosures that are protected under the whistleblower provisions of federal law or regulation, and, for the avoidance of doubt, the Participant is not prohibited from
providing information voluntarily to the Securities and Exchange Commission pursuant to Section 21F of the Exchange Act. The Participant is hereby notified in accordance with the Defend Trade Secrets Act of 2016 that the Participant will not be
held criminally or civilly liable under any federal or state trade secret law for the disclosure of a trade secret that: (A) is made (1) in confidence to a federal, state, or local government official, either directly or indirectly, or to
an attorney; and (2) solely for the purpose of reporting or investigating a suspected violation of law; or (B) is made in a complaint or other document that is filed under seal in a lawsuit or other proceeding. The Participant is further
notified that if the Participant files a lawsuit for retaliation by Company for reporting a suspected violation of law, the Participant may disclose trade secrets to the Participant’s attorney and use the trade secret information in the court
proceeding if the Participant: (x) files any document containing the trade secret under seal; and (y) does not disclose the trade secret, except pursuant to court order. The Participant does not need the prior authorization of Company to
make any such reports or disclosures, and the Participant is not required to notify Company that the Participant has made such reports or disclosures. 

ARTICLE VI 
 TAX MATTERS

 6.1 Section 409A. 

(a) The payments and benefits provided under this Plan will be subject to all applicable federal, state, and other governmental
withholdings.  
 (b) To the extent applicable, it is intended that this Plan comply with or be exempt from the
provisions of Section 409A, so that the income inclusion provisions of Section 409A(a)(1) of the Code do not apply to a Participant. Consistent with that intent, and to the extent required under Section 409A, for benefits that are to
be paid in connection with a termination of employment, “termination of employment” or any similar term will be limited to such a termination that constitutes a “separation from service” under Section 409A. 

(c) Notwithstanding any provision of Section 4.2 of this Plan to the contrary, if a Participant is a “specified
employee,” determined pursuant to procedures adopted by the Company in compliance with Section 409A, on the date of his or her separation from service (within the meaning of Treasury Regulation section
1.409A-1(h)) and if any portion of the payments or benefits to be received by the Participant upon his or her termination of 

  
 13 

Effective December 9, 2022 












 
employment would constitute a “deferral of compensation” subject to Section 409A, then to the extent necessary to comply with Section 409A, amounts that would otherwise be
payable pursuant to this Plan during the six-month period immediately following the Participant’s termination of employment will instead be paid or made available on the earlier of (i) the first
business day of the seventh month after the Termination Date, or (ii) the Participant’s death. For purposes of application of Section 409A, to the extent applicable, each payment made under this Plan will be treated as a separate
payment and not one of a series of payments for purposes of Section 409A. 
 (d) Notwithstanding any provision of this
Plan to the contrary, if (i) as of the date of commencing participation in this Plan, a Participant is or was party to an Other Severance Arrangement, and (ii) the time and form of any payments under this Plan would result in tax penalties
under Section 409A, then, to the extent necessary to avoid tax penalties under Section 409A, any amounts owed pursuant to this Plan will instead be paid (to the extent possible) at the time and in the manner provided for in such Other
Severance Arrangement. 
 (e) Notwithstanding any provision of this Plan to the contrary, if a Participant has entered into
an Other Severance Arrangement concurrent with commencing participation in this Plan, then (i) if the Participant’s Qualifying Termination occurs within two years after a Change in Control that constitutes a “change in the
ownership,” “change in effective control,” and/or a “change in the ownership of a substantial portion of assets” of the Company as those terms are defined under Treasury Regulation
§1.409A-3(i)(5) (a “409A Change in Control”), any amounts owed pursuant to this Plan will be paid at the time and in the manner set forth in this Plan, and (ii) if the
Participant’s Qualifying Termination does not occur within two years after a 409A Change in Control, any amounts owed pursuant to this Plan will instead be paid (to the extent possible) at the time and in the manner provided for in such Other
Severance Arrangement. 
 (f) To the extent any reimbursement or in-kind benefit
provided under this Plan is nonqualified deferred compensation within the meaning of Section 409A: (i) the amount of expenses eligible for reimbursement, or in-kind benefits provided, during a
calendar year may not affect the expenses eligible for reimbursement, or in-kind benefits to be provided, in any other taxable year; (ii) the reimbursement of an eligible expense must be made on or before
the last day of the calendar year following the calendar year in which the expense was incurred; and (iii) the right to reimbursement or in-kind benefits is not subject to liquidation or exchange for
another benefit. 
 (g) In no event will this Section 6.1 or any other provisions of this Plan be construed to require
the Company to provide any gross-up for the tax consequences under Section 409A of any provisions of, or payments under, this Plan, and the Company will have no responsibility for tax consequences under
Section 409A to a Participant resulting from the terms or operation of this Plan.

Effective December 9, 2022 












 6.2 Adjustment of Certain Payments and Benefits. 

(a) Notwithstanding any other provisions in this Plan, in the event that any payment or benefit received or to be received by a
Participant (including, without limitation, any payment or benefit received in connection with a Change in Control or the termination of the Participant’s employment, whether pursuant to the terms of this Plan or any other plan, program,
arrangement or agreement) (all such payments and benefits, together, the “Total Payments”) would be subject (in whole or part) to any excise tax imposed under Section 4999 of the Code, or any successor provision thereto
(the “Excise Tax”), then the Total Payments will be reduced (but in no event to less than zero) in the following order to the extent necessary so that no portion of the Total Payments is subject to the Excise Tax:
(i) cash payments that do not constitute deferred compensation within the meaning of Section 409A of the Code; (ii) cash payments that do constitute deferred compensation within the meaning of Section 409A of the Code;
(iii) acceleration of vesting of equity and equity-based awards and non-cash benefits that do not constitute deferred compensation within the meaning of Section 409A of the Code and
(iv) acceleration of vesting of equity and equity-based awards and non-cash benefits that do constitute deferred compensation within the meaning of Section 409A of the Code (the payments and benefits
in clauses (i), (ii), (iii), and (iv), together, the “Potential Payments”); provided, however, that the Potential Payments will only be reduced if (x) the net amount of the Total Payments, as so reduced (and after
subtracting the net amount of federal, state, municipal and local income taxes on such reduced Total Payments and after taking into account the phase out of itemized deductions and personal exemptions attributable to such reduced Total Payments), is
greater than or equal to (y) the net amount of the Total Payment without such reduction (but after subtracting the net amount of federal, state, municipal and local income taxes on such Total Payments and the amount of Excise Tax to which the
Participant would be subject in respect of such unreduced Total Payments and after taking into account the phase out of itemized deductions and personal exemptions attributable to such unreduced Total Payments). 

(b) For purposes of determining whether and the extent to which the Total Payments will be subject to the Excise Tax:
(i) no portion of the Total Payments the receipt or enjoyment of which the Participant will have waived at such time and in such manner as not to constitute a “payment” within the meaning of Section 280G(b) of the Code will be
taken into account; (ii) no portion of the Total Payments will be taken into account if, in the opinion of the Company, such portion of the Total Payments does not constitute a “parachute payment” within the meaning of
Section 280G(b)(4)(A) of the Code) (including, without limitation, by reason of Section 280G(b)(4)(A) of the Code) and, in calculating the Excise Tax, no portion of such Total Payments will be taken into account which, in the opinion of
the Company, constitutes reasonable compensation for services actually rendered, within the meaning of Section 280G(b)(4)(B) of the Code, in excess of the base amount (as set forth in Section 280G(b)(3) of the Code) that is allocable to
such reasonable compensation; and (iii) the value of any non-cash benefit or any deferred payment or benefit included in the Total Payment will be determined by the Company in accordance with the
principles of Sections 280G(d)(3) and (4) of the Code. The Company and each Participant agree that the determinations described in this Section 6.2 will take the form of a letter from the Company accompanied by calculations prepared by the
Company and certified by a nationally recognized accounting firm selected by the Company.

 ARTICLE VII 

MISCELLANEOUS 
 7.1
Amendments. This Plan may be amended or terminated at any time by the Committee; provided, however, that no amendment or termination may materially adversely affect any Participant without the Participant’s prior written
consent unless the Company provides 12 months’ advance written notice of the amendment or termination to any adversely affected Participant. 

7.2 No Set Off; No Obligation to Seek Other Employment or to Otherwise Mitigate Damages; No Effect Upon Other Plans. The
Company’s obligation to make the payments provided for in this Plan and otherwise to perform its obligations under this Plan will not be affected by any set off, counterclaim, recoupment, defense, or other claim that the Company or any
Subsidiary or affiliate of the Company may have against the Participant. The Participant will not be required to mitigate damages or the amount of any payment provided for under this Plan by seeking other employment or otherwise. The amount of any
payment provided for under this Plan will not be reduced by any compensation or benefits earned by the Participant as the result of employment by another employer or otherwise after the Termination Date. 

7.3 Payments Not Compensation. Any participation by a Participant in, and any terminating distributions and vesting rights
(other than previously defined) under, the Company-sponsored retirement or savings plans, regardless of whether such plans are qualified or non-qualified for tax purposes, will be governed by the terms of
those respective plans. Any salary continuation or severance benefits will not be considered compensation for purposes of accruing additional benefits under such plans. 

7.4 Legal Fees. In the event of a dispute by the Company, a Participant or others as to the validity or enforceability of, or
liability under, any provision of this Plan, each Participant and the Company will be responsible for their respective legal fees and expenses. 

7.5 Payments Are in Lieu of Severance Payments. If a Participant becomes entitled to receive payments under this Plan as a
result of termination of the Participant’s employment, those payments will be in lieu of all other claims or rights that the Participant may have against the Company for severance, separation, and/or salary continuation pay upon that
termination of the Participant’s employment, including pursuant to an Employment Agreement. If a Participant becomes entitled to severance benefits pursuant to the Participant’s Employment Agreement prior to becoming entitled to severance
benefits under this Plan (for example, where a Participant’s Termination Date occurs within six months prior to the date of a Change in Control and the Participant becomes entitled to benefits under this Plan upon such Change in Control), any
amounts paid to a Participant pursuant to Section 4.2 of this Plan will be reduced by and offset dollar-for-dollar by any severance benefits paid to the Participant
under the Participant’s Employment Agreement (if any) or any other severance arrangement in connection with the termination, and the Participant’s benefits under such Employment Agreement or other severance arrangement will cease. 

  
 16 

Effective December 9, 2022 












 7.6 Assistance. During a Participant’s employment with the Company and
thereafter, the Participant will provide reasonable assistance to the Company in litigation and regulatory matters that relate to events that occurred during the Participant’s period of employment with the Company and its predecessors and will
provide reasonable assistance to the Company with matters relating to its corporate history from the period of the Participant’s employment with it or its predecessors. A Participant will be entitled to reimbursement of reasonable out-of-pocket travel or related costs and expenses relating to any such cooperation or assistance that occurs following the Termination Date. 

7.7 Termination of Status as Director or Officer. Notwithstanding anything in this Plan to the contrary, unless otherwise agreed
to by the Company and a Participant prior to the Termination Date, a Participant will be deemed to have automatically resigned from all directorships and offices with the Company and its Subsidiaries, and their affiliates (including joint ventures),
as of the Termination Date. 
 7.8 Notices. Notices and all other communications provided for in this Plan must be in writing
and will be deemed to have been duly given upon receipt (or rejection) when delivered in person or by overnight delivery or mailed by United States registered mail, return receipt requested, postage prepaid, and addressed, if to the Company, to its
principal place of business, attention: Chief Legal Officer, and, if to the Participant, to the Participant’s home address last shown on the records of the Company, or to such other address or addresses as either party may furnish to the other
in accordance with this Section 7.8. 
 7.9 Interpretation. The language in all parts of this Plan will be construed
according to its fair meaning, and not strictly for or against the Company or a Participant. In this Plan, unless the context otherwise requires, the masculine, feminine and neuter genders and the singular and the plural include one another. 

7.10 Non-Waiver of Rights and Breaches. No failure or delay of the Company or the
Participant to exercise any right under this Plan will constitute a waiver unless the time specified for the exercise of such right has expired, nor will any single or partial exercise of any right preclude other or further exercise thereof or of
any other right. The waiver of any default will not be deemed to be a waiver of any subsequent default or other default. 
 7.11
Successors and Assigns. The rights and obligations of the Company under this Plan will inure to the benefit of, and will be binding on, the Company and its successors and assigns, and the rights and obligations (other than obligations to
perform services) of the Participant under this Plan will inure to the benefit of, and will be binding upon, the Participant and the Participant’s heirs, personal representatives, and assigns. 

7.12 Top Hat Plan. This Plan is intended to be a “top hat” plan maintained primarily for a group of management or
highly compensated employees. 
 7.13 Governing Law. The laws of the State of Texas will govern the validity of this Plan, the
construction of its terms, and the interpretation of the parties’ rights and duties. Venue for all disputes will be in Dallas County, Texas. All disputes are subject to personal jurisdiction in Dallas County, Texas. 

7.14 Severability. If any provision of this Plan is or becomes invalid or unenforceable in any jurisdiction or would disqualify
this Plan or any compensation under this Plan under any law deemed applicable by the Committee, such provision will be construed or deemed amended or limited in scope to conform to applicable laws or, in the discretion of the Committee, it will be
stricken, and the remainder of this Plan will remain in full force and effect.

 ARTICLE VIII 

CLAIMS PROCEDURES 

8.1 For purposes of this Article VIII, “Administrator” means the Committee or, to the extent permitted by applicable law and
stock exchange requirements, its delegate. The Administrator has the exclusive right to determine eligibility for benefits under this Plan and to deny or grant a claim, in whole or in part. All claim determinations will be made by the Administrator
in a uniform and nondiscriminatory manner in accordance with the Plan provisions. The Administrator’s decision on a claim for benefits is final and binding on all persons. 

8.2 Any Participant or his or her authorized representative who believes he or she may be eligible for benefits under this Plan may
file a claim for benefits to which the claimant believes he or she is entitled. Claims under this Plan must be made in writing and delivered to the Administrator, in person or by mail, postage prepaid. When a claim has been properly filed, the
Administrator will, within 90 days after receipt of such claim, send to the claimant notice of the grant or denial, in whole or in part, of such claim unless special circumstances require an extension of time for processing the claim. In no event
may the extension exceed 90 days from the end of the initial period. If such extension is necessary, the claimant will be given notice to this effect prior to the expiration of the initial 90-day period. Any
notice of extension will set forth the special circumstances requiring the extension of time and the date by which the Administrator expects to render its decision on the application for benefits. 

8.3 The Administrator will provide the claimant with written notice advising the claimant whether the claim is granted or denied, in
whole or in part. If a claim is denied, in whole or in part, the notice will contain: (a) the specific reasons for the denial; (b) references to pertinent Plan provisions on which the denial is based; (c) a description of any
additional material or information necessary to perfect the claim and an explanation of why such material or information is necessary; and (d) an explanation of the Plan’s claim review procedure, the time limits applicable under the
procedures, and a statement regarding the claimant’s right to bring a civil action under Section 502(a) of ERISA (if applicable) following an adverse benefit determination on appeal. 

8.4 If a claim is denied, in whole or in part, the claimant will have the right to request that the Administrator review the denial,
provided that the claimant files a written request for review with the Administrator no later than 60 days after the date the claimant received written notification of the denial. The request for a review will be in writing and addressed to the
Administrator at the Company’s principal office. The request for review will 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 Administrator may
require the claimant to submit such additional facts, documents, or other material as it may deem necessary or appropriate in making its review. The claimant may submit written comments, documents, records, and other information related to the
benefit claim on appeal. The claimant must be provided, upon request and free of charge, reasonable access to and copies of all records, documents, or information on which the Administrator based its determination.

Effective December 9, 2022 












 8.5 The Administrator will provide the claimant with written notification of the
benefit determination on review within 60 days after a request for review is received, unless special circumstances require an extension of time for processing the review, in which case the Administrator will give the claimant written notification
within the initial 60-day period specifying the reasons for the extension and when such review will be completed (provided that such review will be completed within 120 days after the date on which the request
for review was filed). If the Administrator denies the claim on review, in whole or in part, the notification will set forth, in a manner calculated to be understood by the claimant: (a) the specific reason or reasons for the denial;
(b) specific references to the Plan provisions on which the denial is based; (c) a statement that the claimant is entitled to receive, upon request and free of charge, reasonable access to and copies of any and all records, documents or
information on which the Administrator based its determination; and (d) a description of the claimant’s right to obtain information about such procedures and a statement regarding the claimant’s right to bring a civil action under
section 502(a) of ERISA (if applicable) following the denial on appeal.
