Each Participant may elect to defer all or a portion of his or her annual Incentive Compensation as determined by the Committee; provided, however, the amount of each deferral for each payment of Incentive Compensation shall be at least $2,500. Participants shall always be one hundred percent (100%) vested in the amount they defer.

3.2    Deferral Election. Participants shall make the election to defer Incentive Compensation under the Plan on a Deferral Election Form within such dates as the Committee from time to time establishes; provided, that any such election must be made on or before December 31 of the Participant’s taxable year preceding the taxable year in which the Participant performs the services that give rise to the Incentive Compensation to be deferred. Participants shall make the following determinations on each Deferral Election Form, which determinations shall become irrevocable on December 31 of the Plan Year in which the election is made (or such earlier date in that Plan Year as the Committee may determine):

    (a)    the amount to be deferred with respect to the Participant’s Incentive Compensation to which the election applies pursuant to the terms of Sections 3.1 and 3.2 herein;

    (b)    with respect to the automatic Retirement Deferral election described in Section 5.1(a), the date as of which payments are to commence in accordance with Section 5.1(a) and the form in which such benefits are to be paid in accordance with Section 5.2, subject to the terms and conditions of Article V; and

3.4    Disability or Other Absence. Subject to Section 5.1(d), if the Participant experiences a disability, all previous Deferral Elections will remain in force unless the Committee, in its sole discretion, determines that the Participant has incurred an unforeseeable emergency pursuant to Section 5.3 of the Plan, in which case it will waive, upon the Participant’s

request, such election(s). Subject to the foregoing, if the Participant takes a paid or unpaid leave of absence, all previous Deferral Elections will remain in full force.

4.2    A Participant may transfer amounts credited to the Participant’s Deferred Compensation Account among the investment alternatives specified by the Investment Committee in accordance with such rules and requirements as established by the Investment Committee on a uniform and nondiscriminatory basis.

    (a)    Automatic Retirement Deferral Election. Subject to Section 5.1(b), each Participant shall be deemed to irrevocably elect, with respect to the Incentive Compensation payments deferred in any Plan Year under Section 3.2, a Retirement Deferral, pursuant to which payments under the Plan shall commence, provided that the Participant incurs a Retirement Date and subject to Section 5.6, (i) either (A) within sixty (60) days of the Participant’s Retirement Date, or (B) on the Retirement Distribution Date, and (ii) in the form elected by the Participant in accordance with Section 5.2 of the Plan, each as elected by the Participant in accordance with Section 3.2 (provided, however, that payments must commence in accordance with clause (i)(B) of this Section 5.1(a) if the Participant elects to receive payment in the form provided under Section 5.2(b)). Any election by the Participant to defer Incentive Compensation under Section 3.2 and this Section 5.1 shall not be effective unless the Participant completes the elections described in clauses (i) and (ii) of this Section 5.1(a).

    (b)    Optional Short-Term Deferral Election. In addition to the automatic Retirement Deferral election described in Section 5.1(a), each Participant may also irrevocably elect, with respect to the Incentive Compensation payments deferred in any Plan Year, a Short-Term Deferral, pursuant to which payments under the Plan shall commence only in the form provided under Section 5.2(a) of this Plan on any Short-Term Distribution Date elected by the Participant, provided that such Short-Term Distribution Date shall be no earlier than the Short-Term Distribution Date that is subsequent to three (3) Plan Years following the end of the Plan Year in which the Incentive Compensation would have otherwise been paid to the Participant,1 and provided that such Short-Term Distribution Date occurs prior to the Participant’s Separation from Service. In all events, if a Participant’s Separation from Service occurs prior to the Participant’s Short-Term Distribution Date, the Participant’s Incentive Compensation will be distributed in accordance with Section 5.1(a) or Section 5.1(d), as applicable.

    (c)    Notwithstanding anything in the Plan to the contrary, Incentive Compensation paid after a Participant’s Retirement Date, other Separation from Service or death, is not eligible for deferral and will not be deferred, regardless of the Participant’s prior Deferral Election.

    (d)    Notwithstanding any Deferral Period(s) elected by a Participant pursuant to Section 3.2(b) or 3.2(c), as applicable, and this Section 5.1, and subject to Section 5.6, if a Participant has a Separation from Service prior to Early Retirement Age and prior to the Short-Term Distribution Date, if any, elected by the Participant in accordance with Section 5.1(b),

        (i)    such Participant shall be paid out of the Plan in one (1) lump sum in cash within sixty (60) days after such Separation from Service; or

        (ii)    (A)    with respect to a Participant’s 409A Amount, if the Participant has been on disability leave for a period of six (6) months and the Participant does not retain a right to reemployment under an applicable statute or by contract, such Participant’s 409A Amount shall be paid out of the Plan in one (1) lump sum in cash within sixty (60) days after such six (6) month disability period has elapsed; and

            (B)    with respect to a Participant’s Grandfathered Amount, if any, if the Participant has been on disability leave for a period of twelve (12) months, such Participant’s Grandfathered Amount shall be paid out of the Plan in one (1) lump sum in cash within sixty (60) days after such twelve (12) month disability period has elapsed.

    For purposes of this Section 5.1(d), the amount distributed shall be an amount equal to the value of the Participant’s Deferred Compensation Account on the last business day of the month preceding the date of payment.

5.2    Payment of Deferred Amounts. Subject to Section 5.6(d), payment of a Participant’s Deferred Compensation Account under the Plan shall be made in cash in one of the following forms irrevocably elected by the Participant pursuant to Sections 3.2(b) and 5.1:

    (b)    Installment Payments. Payments shall be made in either five (5) or ten (10) annual installments, as irrevocably elected by the Participant. Subject to Section 5.6, the initial payment shall be made on the Retirement Distribution Date. The remaining installment payments shall be made in the form of cash each year thereafter on the anniversary date of the Retirement Distribution Date (notwithstanding any delay of an initial payment due to the application of Section 5.6), until the Participant’s entire Deferred Compensation Account has been paid. The amount of each installment payment shall be equal to value of the Participant’s Deferred Compensation Account on the Retirement Distribution Date or anniversary date thereof. as applicable (or if that day is not a business day, then on the immediately preceding business day), multiplied by a fraction, the numerator of which is one (1), and the denominator of which is the number of installment payments remaining.

    For purposes of this Plan, an amount shall be deemed distributed on the Short-Term Distribution Date, Retirement Distribution Date or the anniversary of a Retirement Distribution Date, as applicable, if it is distributed no later than the last day of the calendar year in which such applicable date occurs or, if later, by the 15th day of the third calendar month after such applicable date occurs, subject to and in accordance with the provisions of Treasury Regulation section 1.409A-3(d), including without limitation the requirement that the employee shall in no event have the right directly or indirectly to designate the taxable year of payment.

5.3    Unforeseeable Emergency. The Committee shall have the sole authority to alter the timing or manner of payment of amounts from a Participant’s Deferred Compensation Account in the event that the Participant establishes, to the satisfaction of the Committee that the Participant has experienced an unforeseeable emergency, as defined in Treas. Reg. Sec. 1.409A-3(i)(3)(i). In such event, the Committee may, upon the request of the Participant:

    (a)    Provide that all or a portion of the amount previously deferred by the Participant immediately shall be paid to the Participant in a lump sum payment; or

    (b)     Provide that all or a portion of the installments payable over a period of time immediately shall be paid to the Participant in a lump sum payment.

    However, the amount distributed pursuant to this Section 5.3 shall not exceed the amount that is reasonably necessary for the Participant to satisfy the emergency need at the time of distribution, as determined by the Committee in its sole discretion. In determining the amount reasonably necessary to satisfy a Participant’s emergency need, the Committee must take into account any additional compensation that is available to the Participant if the Committee has waived the Participant’s previous Deferral Elections upon the Participant’s request pursuant to Section 3.4.

    The Committee shall determine whether the Participant has experienced an unforeseeable emergency based on the relevant facts and circumstances. An unforeseeable emergency will be deemed to exist in the event of an illness or accident of the Participant or the Participant’s dependent (as defined in Section 152(a) of the Code, without regard to Sections 152(b)(1), (b)(2) and (d)(1)(B)), loss of the Participant’s property due to casualty, or other similar unforeseeable and extraordinary circumstances arising as a result of events beyond the control of the Participant. The Committee’s decision with respect to whether the Participant has experienced an unforeseeable emergency and the manner in which, if at all, the payment of deferred amounts shall be altered or modified, shall be final, conclusive, and not subject to appeal.

    Notwithstanding anything in this Section 5.3 to the contrary, no amounts may be distributed on account of this Section 5.3 if such unforeseeable emergency may be relieved:

    (i)    Through reimbursement or compensation by insurance or otherwise;

    (ii)    By liquidation of the Participant’s assets, to the extent the liquidation of such assets would not itself cause severe financial hardship; or

    (iii)    By cessation of deferrals under the Plan.

5.4    Maximum Deductible Amount. An amount that would otherwise be paid from the Deferred Compensation Account of a Participant in a given Plan Year may be delayed to the extent that the Company reasonably anticipates that if the payment were made as scheduled the Company’s deduction with respect to such payment would not be permitted due to the application of Code Section 162(m). Subject to the first sentence of Section 5.5, amounts not paid as a result of the above limitation shall be paid in the earlier of (a) the Company’s first taxable year in which the Company reasonably anticipates that if the payment is made during such year the deduction of such payment will not be barred by application of Section 162(m), or (b) the period beginning with the date of the Participant’s Separation from Service or death, and ending on the later of (i) the last day of the taxable year of the Company in which the Participant incurs a Separation from Service or dies, or (ii) the 15th day of the third month following the Participant’s Separation from Service or death.

5.5    Death of Participant. A Participant, who at the time of his death is employed by the Company or any Related Company and who dies before a complete distribution of his

Deferred Compensation Account has been made to him, or who has a Separation from Service and subsequently dies before a complete distribution of his Deferred Compensation Account has been paid to him, shall have his remaining Deferred Compensation Account distributed in cash in one (1) lump sum to his Beneficiary. Such distribution shall be made any time during the period beginning on the date of death and ending on December 31 of the first calendar year following the calendar year in which the Participant’s death occurs.

5.6    Limits on Distributions to Key Employees. Anything in the Plan to the contrary notwithstanding, including without limitation Section 5.3, if a Participant is a Key Employee, any distribution of a 409A Amount to such Participant due to the Participant’s Separation from Service that would otherwise be made during the six months following such Separation from Service shall in no event be made earlier than the earlier of (i) the date that is six months and one day following such Separation from Service, or (ii) the Participant’s death.

5.7    Annual Identification of Key Employees. The Specified Employee Identification Date, as defined in Treas. Reg. Sec. 1.409A-1(i)(3), to be used in determining Key Employees of the Company shall be September 30 of any Plan Year. The January 1 of the Plan Year next following that Plan Year shall be the Specified Employee Effective Date, as defined in Treas. Reg. Sec. 1.409A-1(i)(4), for Participants identified as Key Employees on the immediately preceding Specified Employee Identification Date. Participants identified as Key Employees on a Specified Employee Identification Date (September 30) shall be treated as Key Employees under the Plan for the 12-month period beginning on the Specified Employee Effective Date (January 1) next following such Specified Employee Identification Date.

5.8    Grandfathered Amount. Notwithstanding anything herein to the contrary, a Participant’s Grandfathered Amount, if any, shall be paid at the time and in the form determined under the Plan as in effect October 3, 2004.

5.9    409A Amounts Attributable to Service Prior to 2018.

6.2    Authority of the Committees. The Committee shall administer the Plan and shall have full power to select employees for participation in the Plan and to determine the terms and conditions of each employee’s participation; to construe and interpret the Plan and any agreement or instrument entered into hereunder; and to establish, amend, or waive rules and regulations for the Plan’s administration.

7.1    Amendment or Termination. The Corporation has set no termination date for the Plan but reserves the right to amend or terminate the Plan when, in the sole discretion of the Corporation, such amendment or termination is advisable.

Upon termination of the Plan, distribution of amounts in a Participant’s Deferred Compensation Account shall be made to him or his Beneficiary in the manner and at the time described in Article V of the Plan. No additional credits shall be made to the Deferred Compensation Account of a Participant for any Plan Year beginning after the termination of the Plan, but the Company shall continue to credit gains and losses attributable to investments made pursuant to Section 4.1 to such Deferred Compensation Account until the balance of such Account has been fully distributed to the Participant or his Beneficiary.

7.3    Amendments Necessary to Satisfy Code Section 409A. Anything in the preceding Sections 7.1 or 7.2 or elsewhere in the Plan to the contrary notwithstanding:

    (a)    the Plan may be amended in any manner necessary to ensure that the Plan complies in all applicable respects with Code Section 409A; and

    (b)    the Plan may not be amended in any manner that would cause the Plan to fail to comply in any applicable respect with Code Section 409A.

8.1    Plan Unfunded/Participant’s Rights Unsecured. The Plan at all times shall be entirely unfunded and no provision shall at any time be made with respect to segregating any assets of the Company for payment of any benefits hereunder. The Company shall contribute assets to a rabbi trust described in Revenue Procedure 92-64 (the “Trust”) for the purpose of paying benefits under this Plan, and if and to the extent that the Company does so, benefits under the Plan shall be payable pursuant to and in accordance with the Trust Agreement, which shall in all events provide that all assets held thereunder remain subject to the claims of the general creditors of the Company. No Participant, Beneficiary or any other person shall have any interest in any particular assets of the Company or the Trust by reason of the right to receive a benefit under the Plan and any such Participant, Beneficiary or other person shall have only the rights of a general unsecured creditor of the Company with respect to any rights under the Plan and Trust Agreement.

8.2    Tax Withholding. In connection with any deferral under the Plan, the Company shall have the right to withhold from nondeferred Incentive Compensation amounts or other compensation available at the time of the award an amount sufficient to satisfy the FICA tax withholding requirements applicable to such deferrals, or to require the Participant to remit to the Company an amount sufficient to satisfy the tax obligation. In connection with any distribution to the Participant of deferred Incentive Compensation, the Company shall have the right to withhold from such distribution an amount sufficient to satisfy Federal, State, and local tax withholding requirements applicable to such distributions.

8.3    No Guaranty of Benefits. Nothing contained in the Plan shall constitute a guaranty by the Company or any other person or entity that the assets of the Company will be sufficient to pay any benefit hereunder.

8.4    No Enlargement of Employee Rights. No Participant shall have any right to receive a distribution of contributions made under the Plan except in accordance with the terms of the Plan. Establishment of the Plan shall not be construed to give any Participant the right to be retained in the service of the Company.

8.5    Spendthrift Provision. No interest of any person or entity in, or right to receive a distribution under, the Plan shall be subject in any manner to sale, transfer, assignment, pledge, attachment, garnishment, or other alienation or encumbrance of any kind; nor may such interest or right to receive a distribution be taken, either voluntarily or involuntarily, for the satisfaction of the debts of, or other obligations or claims against, such person or entity, including claims for alimony, support, separate maintenance and claims in bankruptcy proceedings.

8.7    Incompetency. Every person receiving or claiming benefits under the Plan shall be presumed to be mentally competent and of age until the Committee receives a written notice, in a form and manner acceptable to it, that such person is incompetent or a minor, and that a guardian, conservator, or other person legally vested with the care of his estate has been appointed. In the event that the Committee finds that any person to whom a benefit is payable under the Plan is unable to properly care for their affairs, or is a minor, then any payment due (unless a prior claim therefor shall have been made by a duly appointed legal representative) may be paid to the Spouse, a child, a parent, or a brother or sister, or to any person deemed by the Committee to be authorized to care for such person otherwise entitled to payment.

    In the event a guardian, executor, administrator, or conservator of the estate of any person receiving or claiming benefits under the Plan shall be appointed by a court of competent jurisdiction, payments shall be made to such guardian, executor, administrator, or conservator provided that proper proof of appointment is furnished in a form and manner

suitable to the Committee. Any payment made under the provisions of this Section 8.7 shall be a complete discharge of any liability therefor under the Plan.

8.8    Successors. The Plan shall not be automatically terminated by a transfer or sale of assets of the Corporation or by the merger or consolidation of the Corporation into or with any other corporation or other entity, but the Plan shall be continued after such sale, merger or consolidation only if and to the extent that the transferee, purchaser or successor entity agrees to continue the Plan. In the event that the Plan is not continued by the transferee, purchaser or successor entity, then the Plan shall terminate subject to the provisions of Section 7.2.

8.9    Unclaimed Benefit. Each Participant shall keep the Committee informed of his current address and the current address of his designated Beneficiary. None of the Corporation, the Company or the Committee shall be obligated to search for the whereabouts of any person. If the Committee is unable to locate the Participant or any Beneficiary of the Participant, then none of the Corporation, the Company or the Plan shall have any further obligation to pay any benefit hereunder to such Participant or Beneficiary and such benefit shall be forfeited; provided, however, that if the Participant or Beneficiary makes a valid claim for any benefit that has been forfeited, the forfeited benefit shall be reinstated.

8.10    Electronic or Telephonic Notices. Any election, notice, direction or other such action required or permitted to be made in writing under the Plan may also be made electronically, telephonically or otherwise, to the extent then permitted by applicable law and the administrative rules prescribed by the Committee.

8.11    Limitations on Liability. Notwithstanding any of the preceding provisions of the Plan, neither the Company, any member of the Committee or the Investment Committee nor any individual acting as an employee or agent of the Company, the Committee or the Investment Committee shall be liable to any Participant, former Participant, Beneficiary or any other person for any claim, loss, liability or expense incurred in connection with the Plan.

8.12    Gender; Headings. Words in the masculine gender shall include the feminine and the singular shall include the plural, and vice versa, unless qualified by the context. Any headings used herein are included for ease of reference only, and are not to be construed so as to alter the terms hereof.

8.13    Compliance with Code Section 409A. The Plan is intended to comply in all applicable respects with the requirements of Code Section 409A and shall be construed and administered so as to comply with that Code section.

3. Article V described the payment provisions applicable to Retirement Deferrals and Short- Term Deferrals. Under the pre-November 1, 2017 Plan, Retirement Deferrals were not automatic. Sections 5.1 and 5.2 provided:

    “5.1 Deferral Period. Pursuant to Section 3.2, each Participant shall irrevocably elect the Deferral Period for the Incentive Compensation payments deferred in any Plan Year; provided that the Deferral Period elected by a Participant shall be either a Short-Term Deferral (as provided under Section 5.1(a)) or a Retirement Deferral (as provided under Section 5.1(b)).

    (a)    If the Participant elects a Short-Term Deferral, payments under the Plan shall commence only in the form provided under Section 5.2(a) of this Plan on any Distribution Date elected by the Participant; provided that such Distribution Date shall be no earlier than the Distribution Date that is subsequent to three (3) Plan Years following the end of the Plan Year in which the Incentive Compensation would have otherwise been paid to the Participant.

    (b)    Subject to Section 5.6, if the Participant elects a Retirement Deferral, payments under the Plan shall commence following the Participant’s Separation from Service after reaching the Participant’s Normal, Early or Postponed Retirement date, as such dates are defined in the Pension Plan (such Separation from Service in those circumstances referred to as a “Retirement Date”), provided that payments under the Plan shall commence, as elected by the Participant in accordance with Section 3.2, either (i) within sixty (60) days of the Participant’s Retirement Date or (ii) on the Distribution Date immediately following the Plan Year in which the Participant’s Retirement Date occurs (provided that payments must commence under (ii) if the Participant elects to receive the payments in the form provided under Section 5.2(b) of the Plan).

    (c)    Notwithstanding anything in the Plan to the contrary, Incentive Compensation paid after a Participant’s Retirement Date or other Separation from Service is not eligible for deferral and will not be deferred, regardless of the Participant’s prior Deferral Election.

    (d)    Notwithstanding any Deferral Period(s) elected by a Participant pursuant to Section 3.2(b) and this Section 5.1, and subject to Section 5.6, if at any time before the end of the elected Deferral Period,

        (i)    a Participant incurs a Separation from Service, such Participant shall be paid out of the Plan in one (1) lump sum in cash within sixty (60) days after such Separation from Service; or

        (ii)    (A)    with respect to a Participant’s 409A Amount, the Participant has been on disability leave for a period of six (6) months, such Participant’s 409A Amount shall be paid out of the Plan in one (1) lump sum in cash within sixty (60) days after such six (6) month disability period; and

            (B)    with respect to the Participant’s Grandfathered Amount, if any, the Participant has been on disability leave for a period of twelve (12) months, such Participant’s Grandfathered Amount shall be

paid out of the Plan in one (1) lump sum in cash within sixty (60) days after such twelve (12) month disability period.

    5.2    Payment of Deferred Amounts. Payment of a Participant’s Deferred Compensation Account under the Plan shall be made in cash in one of the following forms irrevocably elected by the Participant pursuant to Sections 3.2(b) and 5.1:

    (b)    Installment Payments. Payments will be made in either five (5) or ten (10) annual installments, as irrevocably elected by the Participant. Subject to Section 5.6, the initial payment shall be made on the Distribution Date following the Participant’s Retirement Date. The remaining installment payments shall be made in the form of cash each year thereafter (on each anniversary date of the initial payment), until the Participant’s entire Deferred Compensation Account has been paid. The amount of each installment payment shall be equal to the value of the the Participant’s Deferred Compensation Account on the last business day of January immediately prior to each such payment, multiplied by a fraction, the numerator of which is one (1), and the denominator of which is the number of installment payments remaining.

    All benefits hereunder shall be paid from the Trust, as further described in Article IV.”
