This is the amount of the pension payments payable to Participant or Participant's Beneficiary under the Qualified Plan. 3.2 Benefits Under the Plan a. At the time of a Participant's retirement, the following calculation shall be made: i. Any Participant who is not an Executive Participant shall have a calculation made as to the amount their benefits would be under the Qualified Plan using the same formula as described in Section 3.1 hereof, but not taking into account any reduction in benefits or any reduction in the amount of income or time of service used in calculating benefits resulting from any provision of federal, state or local law. ii.

In calculating any reduction for early commence- ment of such benefits, any such Participant's age shall be deemed to be 3 years more than his actual age, with his deemed age not to exceed age 65. b. In any instance where the benefit payable to a Participant or the Participant's Beneficiary under the Qualified Plan is less than the benefit calculated for such Participant in accordance with the applicable provisions of paragraph 3.2(a) above, the Participant or Participant's Beneficiary shall be entitled to receive a pension under the Plan in an amount which when added to the amount the Participant or Partici- pant's Beneficiary is entitled to receive under the Qualified Plan, results in a total amount of pension payments payable to the Participant or Participant's Beneficiary from the Plan plus the Qualified Plan equal to the amount calculated with respect to the Participant or Participant's Beneficiary in accordance with the applicable provisions of paragraph 3.2(a) above. 3.3 Payment of Plan Benefits-Benefits shall be payable to Participants under the terms of any of the following options. a. Benefits under the Plan shall be payable at the same times and intervals as benefits payable under the Qualified Plan. b.

After the payment described in this Section 3.3(b) is made, the Company shall have no further obligation to the Partici- pant or the Participant's Beneficiary under this Plan. In calculating such Net Present Value Amount, the Determination 3 Date shall be the date on which the Participant exercised his or her option under this Section. Such net Present Value Amount shall be paid to the Participant as soon as practical, but not more than 30 days after the Determination Date. c.

The Participant shall have the option to change such election from time to time provided that such change is made no later than three months prior to the termination of the Participant's employment with the Company. After the payment described in this Section is made, the Company shall have no further obligation to the Partici- pant under this Plan. In calculating the Net Present Value Amount in regard to this Section 3.3(d), the Determination Date shall be the first day of the month preceding the Participant's termination of employment. d.

At the election of an Executive Participant (or his spouse if the Executive Participant is deceased) following the commencement of retirement payments to an Executive Partici- pant or his spouse under the Qualified Plan and the SERP (but not if employment termination is for Cause, as defined in the Change in Control Agreements), the Company shall fund the Trust in an amount equal to the Net Present Value Amount. In 4 calculating such net Present Value Amount, the Determina- tion Date shall be the date on which Executive Participant or his spouse exercises the option under this Section. c. Funding of the Trust,either under this Section or voluntarily by the Company, will not relieve the Company of any of its payment obligations under this Plan, and such obligations will be fulfilled only upon actual payment in accordance with this Plan. d. If the Trust is funded at the time a payment is required under this Agreement, the payment will be made on behalf of the Company by the Trustee out of Trust funds to the extent permitted by the Trust; provided that the making of such pay- ment shall not reduce the balance in the Trust below the Net Present Value Amount (as defined in Section 3.5) of the then remaining payments to all Participants.

At any time when it is determined that the remaining assets of the Trust are reduced to an amount below the Net Present Value Amount of all remaining payments to all Participants, the Company shall, within six months of such determination, deposit an amount in the Trust so that the assets of the trust are at least equal to the Net Present Amount of all remaining payments to all Participants. The readjustment of the Trust assets shall not take into account the benefits payable to an Executive Participant or his spouse with re- spect to which an election has been made pursuant to Section 3.5 to fund the Trust with an annuity. e. In the event all required payments are made to all Partici- pants or their Beneficiaries,all funds remaining in the Trust shall be immediately delivered to the Company. f. The Company shall instruct that the periodic payments on any annuity policy purchased pursuant to Section 3.5 commence no later than twelve months from the date of the annuity purchase. 3.5 Net Present Value Amount - For the purpose of determining the amount needed to fund the Trust as described in Section 3.4 or the amount of payments to be made as described in Section 3.3, the Company's independent actuaries will calculate the net present value of all payments remaining to be made to Participant or Participant's Beneficiary under this Plan (herein the "Net Present Value Amount"). The Net Present Value Amount shall be determined as of the Determination Date (herein the "Determination Date") in accordance with the provisions of Annex B attached. Notwithstanding anything in this Agreement to the contrary, at the election of an Executive Participant (or his spouse if the Executive Participant is deceased) following the commencement of retirement payments to an Executive Participant or his spouse under the Qualified Plan and the SERP (but not if 5 employment termination is for Cause, as defined in the Change in Control Agreements), the Company shall fund the Trust with either (a) an amount equal to the single premium necessary to purchase an annuity or (b) an annuity policy, that provides payments approximately equal to the annual benefit described and calculated in accordance with this Plan. The Company has discretion to (i) reject such election if a single premium for such annuity policy exceeds the Net Present Value Amount and (ii) purchase an annuity policy from an insurance carrier rated A or better with AM Best to provide the Trust with the annual benefit described herein. In the same manner, the Trust shall state that the Executive Participant (or his spouse if the Executive Participant is deceased) following the dates stated in this subparagraph can instruct the trustee to use Trust assets to purchase an annuity.
