1.2  Applicability of the Plan

Except as otherwise specifically provided herein, the provisions of this Plan apply only to Participants (or beneficiaries of Participants) who participate in
the Plan on or after January 1, 2016. Any employee who separated from service or otherwise became entitled to receive benefits under the Plan prior to January 1, 2016 (or beneficiary thereof) shall have his rights determined under the
provisions of the Plan as it existed at such time; provided that to the extent certain provisions of this Plan became effective prior to January 1, 2016, those same provisions shall apply to Participants (or beneficiaries) who participate in
the Plan after that effective date.

1.3  Purpose

This Plan is intended to fully restore pension benefits under a tax-qualified pension plan that would otherwise have
been provided to a select group of eligible employees in the absence of certain restrictions imposed by the Internal Revenue Code. This Plan supersedes all other restoration plans covering the Participants under this Plan. The Plan is intended to be
a plan within the meaning of section 201(2) of the Employee Retirement Income Security Act of 1974, as amended, that is unfunded and maintained primarily for the purpose of providing deferred compensation for a select group of management or
highly compensated employees (top-hat plan).

9.4  Correction of Errors

The Committee shall have the authority to correct any error in the calculation of a Participants
benefit or the amount paid to a Participant or Beneficiary, regardless of the reason for the error and regardless of whether payment of the benefit has commenced. By his participation in the Plan and acceptance of benefits hereunder, each
Participant agrees that he will promptly repay to the Plan any payment that exceeds the amount to which he was entitled under the Plan (an excess payment), and will hold any excess payment, and any proceeds of any excess payment, or
property acquired with any excess payment, in trust for the benefit of the Plan, which trust shall remain in effect, and shall continue to apply to any excess payment, proceeds or other property even if transferred to a third party, until the total
amount of the excess payment has been repaid to the Plan. The Committee may, on behalf of the Plan, commence an action to enforce such trust, or take any other available action in law or equity, including setting off any other amount owed to the
Participant, to recover such excess payment.

Article 10. Amendment and Termination

The Board reserves the right to amend, modify, or terminate the Plan at any time for any reason. Such right shall be exercised only by a written resolution or
other written instrument approved by the Board.

The Committee shall also have the right to amend the Plan without obtaining the approval of the Board of
Directors if the amendment does not



|(a) | have the effect of terminating the Plan;
|--- | ----------------------------------------



|(b) | materially increase the cost of providing benefits under the Plan, unless the amendment conforms the Plan with legislation, governmental regulations, rules, or interpretive bulletins expressing a public policy or
condition with which the Plan must comply;
|--- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(c) | revise this Article to increase the Committees authority to amend the Plan or derogate from the authority of the Board of Directors; and
|--- | -----------------------------------------------------------------------------------------------------------------------------------------



|(d) | confer any special advantage whether economic or otherwise, whether present or contingent, on the Committee or its members.
|--- | ---------------------------------------------------------------------------------------------------------------------------

The Committee may exercise its right to amend the Plan only by a written resolution or other written instrument
approved by the Committee.

No amendment or termination may adversely affect the rights or benefits of a Participant previously accrued and vested under
the Plan without the consent of the Participant.

In the event of the Plan termination, all benefits shall be distributed to the Participants as otherwise
provided in the Plan; provided, however, that the Committee and the Board have reserved their right to accelerate payments of benefits to the Participant to the extent that and in a manner permitted by the 409A Guidance.
