A termination of employment does not occur if the individual is on military leave, sick leave, or other bona fide leave of absence, provided the leave of absence does not exceed 6 months or such longer period as the individual retains a right to reemployment pursuant to statute or contract, and there is a reasonable expectation that the individual will return to perform services for the Company or any Affiliate. This Section shall be interpreted and applied in accordance with Treasury Regulation Section 1.409A-1(h).

1.19    “Vested” means that a Participant is fully vested in his or her Qualified Plan Benefit.

2.01    Eligibility.

(a)    A Vested Participant shall be entitled to receive a Supplemental Plan Benefit as of his or her Eligibility Date. The amount of such benefit shall be determined in accordance with Section 2.02.

(b)    If a Vested Participant dies prior to his or her Eligibility Date, and is survived by a spouse, then a death benefit shall be payable with respect to the Participant in accordance with Section 2.03. If a Participant dies after retirement benefits commence, then a death benefit shall be payable with respect to such Participant only to the extent provided by the form in which such benefit is being paid.

(c)    A Participant who terminates employment with the Company and all Affiliates prior to becoming Vested shall not be eligible to receive any Supplemental Plan Benefits.

2.02    Accrued Supplemental Benefit. The Participant’s accrued Supplemental Plan Benefit as of his or her Eligibility Date shall equal the difference between (a) and (b):

(a)    The amount that would be the Participant’s accrued Qualified Plan Benefit as of such date if the qualified benefit were determined on the basis of Earnings under this Plan and without regard to any Qualified Plan provisions incorporating the limits of Code Sections 415 or 416, in the form of a Life Income Benefit (as defined in the Qualified Plan), assuming that payment commences on the Eligibility Date.

(b)    The amount of the Participant’s actual accrued Qualified Plan Benefit as of such date, in the form of a Life Income Benefit (as defined in the Qualified Plan), assuming that payment commences on the Eligibility Date.

2.03    Death Benefit. The monthly benefit payable to the surviving spouse of a Participant who dies before his or her Eligibility Date shall be equal to the benefit that would have been payable to such spouse under the 66⅔% Joint and Contingent Income Benefit described in Section 3.01(b), based on the following assumptions:

(a)    In the case of a Participant who dies after attaining age sixty (60), such Participant had terminated employment and commenced Supplemental Plan Benefit payments immediately before his or her death, or

(b)    In the case of a Participant who dies prior to attaining age sixty (60), such Participant had terminated employment on the earlier of his or her actual termination date or date of death, survived to age sixty (60), and commenced Supplemental Plan Benefit payments on the day immediately prior to his or her death.

2.04    Grandfathered Benefits. If a Participant terminated employment with the Company and all Affiliates before January 1, 2005, then his or her rights and benefits shall not be determined under this amended and restated Plan, but shall be determined strictly in accordance with the terms of the Plan as in effect on December 31, 2004, including, but not limited to, all provisions relating to the amount, time of payment and form of distribution of Supplemental Plan Benefits.

3.01    Form and Time. Except as provided in Section 3.04, a Participant’s Supplemental Plan Benefit shall commence to be distributed to the Participant as of the first day of the month next following his or her Eligibility Date under Section 2.01(a), and the form of payment shall be determined by the Participant’s marital status on the benefit commencement date.

(a)    If the Participant is not married on the benefit commencement date, the Supplemental Plan Benefit shall be a Life Income Benefit. The Life Income Benefit provides a monthly benefit payable for the Participant’s life and ceases with the monthly payment due immediately preceding the Participant’s death.

(b)    If the Participant is married on the benefit commencement date, the Supplemental Plan Benefit shall be an actuarially equivalent 66⅔% Joint and Contingent Income Benefit. The 66⅔% Joint and Contingent Income Benefit provides a monthly benefit payable for the Participant’s life, and, if the Participant predeceases his or her spouse, a monthly survivor benefit payable for the further life of the spouse equal to sixty-six and two thirds percent (66⅔%) of the monthly benefit payable during the Participant’s life. Benefit payments shall cease with the monthly payment due immediately preceding the later of the Participant’s death and the Participant’s spouse’s death.

3.02    Distributions Upon Death. In the event of a Participant’s death before commencement of his or her Supplemental Plan Benefit, the pre-retirement death benefit payable to the Participant’s surviving spouse shall commence as of the first day of the month next following the Participant’s date of death or, if later, the date on which he or she would have attained age sixty (60), in the form of a monthly benefit for the surviving spouse’s lifetime.

3.03    Distributions to Key Employees. Effective January 1, 2005, notwithstanding any other provision of the Plan (including the January 1, 2000 amendment and restatement of the Plan) to the contrary, in the case of a Participant who is a Key Employee on his or her termination of employment date, distributions shall commence as of the later of:  (a) the date distributions otherwise would begin without regard to this Section 3.03 and (b) the six-month anniversary of the Participant’s termination of employment date or, if earlier, the Participant’s date of death. No interest shall be accrued during the six-month period if benefit commencement is postponed pursuant to subsection (b) and Code Section 409(A)(a)(2)(B)(i).

3.04    Distributions Pursuant to Transition Rules. Notwithstanding Section 3.01 to the contrary:

(a)    Effective January 1, 2007, each eligible Participant (as described below) shall be permitted to make an election regarding the time and form of distribution of his or her total Supplemental Plan Benefit. The election shall be made before December 31, 2007 (or such earlier date as the Administrator shall specify), in accordance with procedures established by the Administrator pursuant to IRS Notice 2005-1, Q&A-19(c), IRS Notice 2006-79 § 3.02, and the transition rules set forth at 72 Fed. Reg. 19,272.

A transition election under this subsection (a) shall be irrevocable; provided that, if the marital status of an eligible Participant who makes a transition election is different on the benefit commencement date than on the date of his or her transition election, the Participant shall be permitted (i) to choose payment in the form of any other actuarially-equivalent life annuity that he or she could have elected at the time of making the transition election, and (ii) in connection therewith, to change his or her beneficiary, if any. No other changes to a transition election shall be permitted.

(b)    Distributions that commence before January 1, 2008, shall be determined in accordance with the provisions of the Plan as in effect on December 31, 2004.

(c)    Distributions to a Participant who has an accrued Supplemental Plan Benefit attributable to Plan Years before 2008, but who is not eligible to make a transition election under

subsection (a); to whom distributions have not commenced as of January 1, 2008; and who has attained age 60 as of such date shall commence on or before July 1, 2008.

3.05    Distributions Pursuant to Domestic Relations Orders. The distribution of benefits under the Plan shall be subject to the terms of any domestic relations order with respect to a Participant that is either –

(b)    A domestic relations order regarding the Participant’s aggregate benefits under this Plan and the Qualified Plan that has been determined by the Qualified Plan administrator to be a qualified domestic relations order within the meaning of Code § 414(p).

3.06     Other Limitations. The Administrator may require a claimant for a distribution hereunder to furnish such information as it may reasonably request, and may delay the commencement of a distribution, if necessary, until such information is made available.
