such Separation from Service occurs and the 15th day of the third month following such Separation from Service. No election shall be provided to the
Participant with respect to the timing of payment pursuant to this Section 4.3(b). To the extent that payment of the Supplemental Plan Retirement Benefit is delayed pursuant to this Section 4.3(b) by reason of Code Section 162(m),
interest at the rate(s) specified in Section 4.3(d) shall be paid on such delayed payment for the period between March 2, 2008 and the date of payment. If a Participant whose payment is delayed pursuant to this Section 4.3(b) dies
after March 2, 2008 and before his entire Supplemental Plan Retirement Benefit is paid to such Participant, the unpaid portion of such lump sum Actuarial Equivalent of the Participant’s Supplemental Plan Retirement Benefit (with interest
at the rate(s) specified in Section 4.3(d) for the period between March 2, 2008 and the date of death) shall be paid to the surviving Spouse of the Participant or, if none, to the Participant’s estate in accordance with this

 5 








 (d) To the extent that interest is to be paid pursuant to Section 4.3(a) or 4.3(b),
such interest shall be determined using the average annual interest rate on 30-year Treasury securities (as specified by the Commissioner of the Internal Revenue Service in revenue rulings, notices or other guidance published in the Internal Revenue
Bulletin) for the November preceding the month containing the first day of the Plan Year(s) comprising the period of delay. 
 (e) A surviving Spouse who receives payment pursuant to Section 4.3(a) or 4.3(b) shall not be eligible to receive payment pursuant to Section 4.6. 
 4.4 Payment to Participants and Joint Annuitants in Pay Status as of December 31, 2007. 
 (a) A Participant or surviving Spouse or other surviving joint annuitant, as the case may be, who commences payment of his Supplemental Plan Retirement Benefit or survivor annuity prior to January 1, 2008 shall be permitted to elect to
cease, as of December 31, 2008, monthly payments of such benefit and to receive the unpaid portion of either his Supplemental Plan Retirement Benefit or survivor annuity, as the case may be, as an Actuarial Equivalent single lump sum paid on
January 5, 2009. Such lump sum payable to a Participant also shall reflect the value of any survivor annuity option previously elected by such Participant; provided that the Spouse or other joint annuitant is alive as of January 5,
2009. To make an election pursuant to this Section 4.4(a), a Participant must obtain the written, notarized consent of his Spouse (if any). Any election pursuant to this Section 4.4 shall not apply to the portion of such Supplemental Plan
Retirement Benefit or survivor annuity that would otherwise be paid in 2007 in accordance with the Prior Plan. Any election pursuant to this Section 4.4. may be changed at any time before December 1, 2007 and shall become irrevocable as of
December 1, 2007. 
 (b) If an eligible Participant who is receiving payment of his Supplemental Plan Retirement
Benefit in the form of a joint and survivor annuity makes the election permitted pursuant to Section 4.4(a), and dies after December 31, 2007 and prior to January 5, 2009, the value of any survivor annuity option previously elected by
such Participant and still in effect shall be paid on the first day of the month following the date of the Participant’s death to the surviving Spouse (if any) or other surviving joint annuitant (if any), as the case may be, in a single lump
sum that is the Actuarial Equivalent of such survivor annuity as of the date immediately prior to the date of the Participant’s death. A surviving Spouse or other joint annuitant of a Participant receiving payment of his Supplemental Plan
Retirement Benefit in the form of a single life annuity shall not be eligible for the payment pursuant to this Section 4.4(b).

payable, a Supplemental Plan Retirement Benefit equal to the excess (if any) of (a) over the sum of (b) and (c) where: 
 (a) is the Pension Plan Preretirement Death Benefit that would be payable for the month in which payment is made determined as if (i) the limitations imposed by Code Sections 401(a)(17) and 415 are not imposed
and determined without regard to any requirement in the Pension Plan regarding the date on which such payment may actually commence and (ii) Supplemental Plan Compensation and Supplemental Plan Final Average Compensation have the meaning given
such terms under Article II of this Supplemental Plan;

seventh month. 
 (b) neither the Committee nor the Administrator shall have the discretionary authority to delay payment of a
Supplemental Plan Retirement Benefit or Supplemental Plan Preretirement Death Benefit except to the extent that the Committee or the Administrator determines in its discretion, that any such delay will not cause any person to incur any tax, interest
payment or penalty pursuant to Section 409A (“Section 409A Compliance”).

such denial must request a review of the Administrator’s decision by filing a written request with the Committee for such review within 60 days after the Claimant’s receipt of such claim denial. Such request for review shall contain, and
the Committee shall review all comments, documents, records and other information relating to the claim for benefits that the Claimant wishes the Committee to review, without regard as to whether such information was submitted or considered in the
initial review of the claim by the Administrator. In connection with that review, the Claimant shall be provided, upon request and free of charge, reasonable access to and copies of all documents, records or other information relevant to the claim.
Written notice of the decision on review shall be furnished to the Claimant within 60 days after receipt by the Committee of a request for review. However, in the event of special circumstances, the response period can be extended for an additional
60 days, as long as the Claimant receives an Extension Notice before the end of the initial 60-day response period indicating the reasons for the extension and the date by which the Committee expects to make a decision. The Committee’s
