ARTICLE III - BENEFITS

III.1 Determination of Benefits . The Supplemental Retirement Benefit payable to the Participant is a monthly benefit that is equal to the amount computed under Section 3.1(a) below, minus the amount computed under Section 3.1(b) below where:

(a)

equals the hypothetical Accrued Projected Monthly Retirement Benefit that would have been payable to the Participant under the Qualified Plan commencing on the applicable benefit commencement date under the Qualified Plan, and taking into account any reduction for benefits commencing between the Participant's Early Retirement Date and Normal Retirement Date, or any increase in benefits commencing between the Participant's Normal Retirement Date and Late Retirement Date, without regard to:

(i) the applicable limits under Code Sections 415 and 401(a)(17) or similar provisions restricting the amount of compensation or benefits that may be considered under plans qualified pursuant to Code Section 401(a), including the Qualified Plan; or

(ii) any limitations in the event of inadequate funding as set forth in Article XVII of the Qualified Plan; and

(b) is the Participant's actual Accrued Projected Monthly Retirement Benefit under the Qualified Plan commencing on the applicable benefit commencement date under the Qualified Plan, and taking into account any reduction for benefits commencing between the Participant's Early Retirement Date and Normal Retirement Date or any increase in benefits commencing between the Participant's Normal Retirement Date and Late Retirement Date, without regard to any limitations in the event of inadequate funding as set forth in Article XVII of the Qualified Plan.

The amount of the benefits calculated under Section 3.1(a) and Section 3.1(b) shall be calculated in the same manner and using the same actuarial and other factors, including but not limited to any early commencement or late commencement factors, as applied under the Qualified Plan.

III.2 Time of Calculation . A Participant's Supplemental Retirement Benefit calculated under Section 3.1 is calculated as of the Participant's Benefit Commencement Date and will not be recalculated thereafter.

III.3 Vesting . The Participant's Supplemental Retirement Benefit is fully vested at all times.  

III.4 Form of Benefit . The Supplemental Retirement Benefit payable to a Participant shall be payable as a Single Life Annuity with Ten Years Certain.

III.5 Benefit Commencement Date . Subject to any delay in accordance with Section 3.9, benefits under this Plan commence on the Participant's Benefit Commencement Date.

III.6 Mandatory Cash-Out . Notwithstanding anything in this Article, if the Participant's Supplemental Retirement benefit has an Actuarial Equivalent single-sum value less than $50,000  on the Participant's Benefit Commencement Date of the Participant's Separation from Service, the Participant's Supplemental Retirement Benefit will be distributed in a single lump-sum payment within thirty (30) days after the date of the Participant's Benefit Commencement Date.

III.7 Reemployment; Nonduplication . If a Participant becomes reemployed as an employee after the Benefit Commencement Date, the Participant shall continue to receive payment

of the Supplemental Retirement Benefit from the Plan, but, until the Participant again Separates from Service, the amount of such payments will not be increased by any benefits accrued following the Participant's reemployment. In calculating the Supplemental Retirement Benefit after Separation from Service following reemployment, the Participant's prior service and earnings will be taken into account regardless of whether a prior payment of benefits to the Participant has been made under the Plan. Any additional benefits that accrue will be treated as a separate benefit under the Plan and will be distributed in accordance with the terms of this Article III.

III.8 Delay for Specified Employees . Notwithstanding any other provision of the Plan to the contrary, if a Participant is a specified employee (within the meaning of Code Section 409A(a)(2)(B)(i) and other issued Treasury Regulations and interpretive guidance) and benefits commence on account of that Participant's Separation from Service (other than on account of the Participant's death or where such payment is otherwise payable more than six (6) months after such Separation from Service), the Benefit Commencement Date will be delayed until the first business day of the seventh (7 ^th ) month following the month in which the Participant Separates from Service. During this six-month delay period, all benefit payments which otherwise would have been made during such six-month period shall accumulate without interest and be paid as a lump sum on the first business day of the seventh (7 ^th ) month at the time other benefit payments commence.

ARTICLE IV - DEATH BENEFITS

IV.1 Death Benefit Prior to Commencement .

(a) Amount . The death benefit payable to the Participant's Eligible Spouse or Designated Beneficiary shall be one hundred twenty (120) monthly payments commencing on the first day of the month following the month in which the Participant would have attained his or her Normal Retirement Age if he or she had not died, with each such monthly benefit payment equal to the difference between the monthly benefits determined under Section 4.1(a)(i) and Section 4.1(a)(ii) below where:

(i) equals the hypothetical Accrued Projected Monthly Retirement Benefit that would have been payable to the Participant under the Qualified Plan commencing on his or her Normal Retirement Date and payable as a Single Life Annuity with Ten Years Certain if he or she had ceased to be an employee of the Company as of the date of his or her death, without regard to:
