Article 2. Participation

2.1    Participation. An Eligible Employee shall become a Participant in the
Plan as of the date the Eligible Employee is first designated by the Company to
receive a Restoration Benefit. An Eligible Employee who becomes a Participant
will continue to be a Participant as long as an Account is being maintained (or
is required to be maintained under the terms of the Plan) for such individual.

Article 3. Restoration Benefits

3.1    Eligibility. A Participant shall be credited with a Restoration Benefit
for each Plan Year beginning on or after January 1, 2019 in which the
Participant is an Eligible Employee who has been designated by the Company in
its sole discretion to receive a Restoration Benefit allocation.

3.2    Amount. A Participant’s Restoration Benefit shall be an amount equal to
six percent (6%) of the excess, if any, of the Participant’s Compensation for
the Plan Year, over the applicable limitation amount under Section 401(a)(17) of
the Code for such Plan Year.

Article 4. Participant Accounts

4.1    Restoration Benefit Credits to Account. The amount of a Participant’s
Restoration Benefit for any Plan Year will be credited as of a date or dates
selected by the Company, but not later than the last day of the Plan Year, to an
account established for the Participant under the Plan. A Participant’s Account
will be a bookkeeping entry only and will be utilized solely as a means of
measuring and determining the amounts to be paid to or in respect of the
Participant.

4.2    Deemed Earnings. Amounts credited to the Participant’s Account deemed to
be invested in the investment fund options that the Company has designated for
this purpose and

- 3 -

--------------------------------------------------------------------------------

Exhibit 10.24

which the Participant has elected in accordance with Section 4.3. The Company
will determine, from time to time and in its discretion, the exact times and
methods for crediting or charging each Participant’s Account with the earnings,
gains or losses and changes in value of such investment funds.

4.3    Investment Funds. The Company will determine from time to time the
investment fund or funds available for hypothetical investment of Participants’
Accounts. Each Participant may elect at such times and in the manner specified
by the Company one or more investment funds in which the Participant’s Account,
or any portion of the Account, will be deemed to be invested for purposes of
determining the amount of earnings, gains or losses to be credited to his or her
Account. If a Participant fails to elect an investment fund with respect to any
portion of his or her Account, the Participant will be considered to have
elected the default investment fund designated by the Company for this purpose.

4.4    Vesting. Subject to the rights of general creditors set forth in Article
8 and the right of the Company to discontinue the Plan as provided in Article
11, a Participant will at all times have a 100% nonforfeitable interest in his
or her Account.

Article 5. Timing and Form of Benefit Distributions

5.1    Account Payments. Except as provided in Article 6, a Participant’s
interest in his or her Account will be paid in a single lump sum as soon as
administratively feasible following his or her Separation from Service, but in
no event later than the time prescribed by Section 1.409A-3(d) of the Treasury
Regulations.

5.2    Delay in Payments. Notwithstanding the foregoing provisions of this
Article 5, if the Participant is a Specified Employee, then any payment on
account of the Participant’s Separation from Service shall not be made until the
date that is six months and two days after such Separation from Service (or, if
earlier, the first day of the month after the Participant’s death). Any payment
otherwise required to be made to a Participant may also be delayed to the extent
permitted by Section 409A of the Code if the Company reasonably determines that
the payment (A) will not be deductible for federal income tax purposes by reason
of the application of Section 162(m) of the Code; (B) will violate federal
securities law or other applicable law; or (C) may be delayed for any other
reason permitted under Section 409A of the Code.

5.3    Benefit Payment Dates. The date on which a Participant’s benefit under
the Plan is paid will be determined at the sole discretion of the Committee in
accordance with the foregoing provisions of this Article 5 or the provisions of
Article 6, whichever apply.

Article 6. Death Benefits

6.1    Payments to Beneficiaries. If a Participant who is entitled to receive a
payment of his or her benefit under the Plan dies before receiving such benefit,
the amount of the Plan benefit will be paid to beneficiary or beneficiaries
designated by the Participant in accordance
with rules and procedures established by the Company. If upon the death of the
Participant there is, in the opinion of the Company, no designated beneficiary
or beneficiaries, such benefit will be paid to the Participant’s estate.

- 4 -

--------------------------------------------------------------------------------

Exhibit 10.24

6.2    Payment of Death Benefit. Payments pursuant to this Article 6 will be
made as soon as practicable after the Participant’s death. Prior to such
payment, a copy of the death notice or other sufficient documentation must be
filed with and approved by the Company.

Article 7. Prohibition on Acceleration of Benefits

7.1    In General. The time or schedule of any payment to be made under the Plan
may not be accelerated except to the extent permitted under Section 409A of the
Code. Where Section 409A of the Code permits a payment to be accelerated but
does not require the Plan to, and the Plan does not, expressly provide for such
acceleration, the payment may be accelerated in the sole discretion of the
Company.

7.2    Change in Control. Notwithstanding the foregoing prohibition on
acceleration of benefits, upon a Change in Control the Company will have the
right, but not the obligation, to terminate the Plan and to distribute each
Participant’s Plan benefit no earlier than 30 days before and no later than 12
months after the date of the Change in Control.

Article 8. Funding of Benefits

8.1    Unfunded Plan. The Plan will be unfunded. All benefits payable to a
Participant under the Plan will be paid from the general assets of the
Participating Employers that employed the Participant, and nothing contained in
the Plan will require the Participating Employers to set aside or hold in trust
any funds for the benefit of a Participant, who will have the status of a
general unsecured creditor with respect to the obligation of the Participating
Employers to make payments under the Plan. Any funds of the Participating
Employers available to pay benefits under the Plan will be subject to the claims
of general creditors of the Participating Employers and may be used for any
purpose by the Participating Employers.

8.2    Liability of Participating Employers. If the benefits payable under the
Plan to a Participant are attributable to periods of employment with more than
one Participating Employer, the Company may allocate liability for the payment
of the benefit among the Participating Employers in any manner the Company, in
its sole discretion, determines to be appropriate.

8.3    Establishment of Trust. Notwithstanding the provisions of Section 8.1,
the Company may, at its discretion, transfer to the trustee of one or more
trusts from which all or a portion of the benefits provided under the Plan will
be satisfied, provided that such assets held in trust will at all times be
subject to the claims of general unsecured creditors of the Participating
Employers, and no Participant will at any time have a prior claim to such
assets. To the extent that benefits under the Plan are paid from any such trust,
the Participating Employers will be relieved of all liability for such benefits.
This Section shall be subject to the terms of the Trust
Agreement dated December 17, 2018, by and between the Company and Fidelity
Management Trust Company, as from time to time in effect, but such terms shall
not apply to the extent they would cause any benefits under the Plan to be
subject to the tax imposed under Section 409A of the Code.

Article 9. Administration of the Plan

- 5 -

--------------------------------------------------------------------------------

Exhibit 10.24

9.1    Administration by the Company. This Plan shall be administered by the
Company. The Company shall perform and exercise all of the duties and powers

functions shall be to act for the Company in the administration of the Plan and

9.2    Compliance with Section 409A. The Plan is intended to provide
compensation and benefits that are not subject to the tax imposed under Section
409A of the Code and shall be interpreted and administered to the extent
possible in accordance with such intent.

Article 10. Claims Procedure

10.1    Claims Procedure. If any person (hereinafter called the “Claimant”)
feels that he or she is being denied a benefit to which he or she is entitled
under this Plan, such Claimant may file a written claim for said benefit with
the Management Committee. Within 60 days of the receipt of such claim (or within
120 days of the receipt of such claim if special circumstances require an
extension of the time for processing the claim, in which event the Management
Committee or its designated representative will furnish the Claimant with a
written notice indicating the special circumstances and the time by which a
determination with respect to the claim will be made), the Management Committee
or its designated representative shall determine and notify the Claimant as to
whether he or she is entitled to such benefit. Such notification shall be in
writing and, if denying the claim for benefit, shall set forth the specific
reason or reasons for the denial, make specific reference to the pertinent
provisions of this Plan, and advise the Claimant that he or she may, within 60
days of the receipt of such notice, in writing request the Management Committee
to review such denial. In connection with such request for review, the Claimant
and/or his or her duly authorized representative may examine copies of any
relevant documents and submit information and comments in writing to support the
granting of the benefit being claimed. The final decision of the Management
Committee with respect to the claim being reviewed shall be made within 60 days
following the receipt of the Claimant's request for review unless special
circumstances
require an extension of time for reviewing the claim, in which event (i) the
Management Committee or its designated representative will furnish a written
notice of such extension to the Claimant, and (ii) the final decision of the
Management Committee shall be made as soon as possible but in no event later
than 120 days after the receipt of the Claimant's request for review. The
Management Committee shall in writing notify the Claimant of its final decision,
again specifying the reasons therefor and the pertinent provisions of this Plan
upon which such decision is based. The final decision of the Management
Committee with respect to a claim shall be conclusive and binding upon the
Claimant and all other parties having or claiming to have an interest in such
claim.
