        The Executive's beneficiary may petition the Company to pay the present
        value of this death benefit in a lump sum and the Company, in its sole
        discretion, may accept or deny said petition.

        3.2     Death During Payment of a Lifetime Benefit. If the Executive
dies after any Lifetime Benefit payments have commenced under Article 2 of this
Agreement but before receiving all such payments, the Company shall pay the
remaining benefits to the Executive's beneficiary at the same time and in the
same amounts they would have been paid to the Executive had the Executive
survived.

        3.3     Death After Termination of Employment But Before Payment of a
Lifetime Benefit Commences. If the Executive is entitled to a Lifetime Benefit
under Article 2 of this Agreement, but dies prior to the commencement of said
benefit payments, the Company shall pay the same benefit payments to the
Executive's beneficiary that the Executive was entitled to prior to death except
that the benefit payments shall commence on the first day of the month following
the date of the Executive's death.

                                    ARTICLE 4
                                  BENEFICIARIES

        4.1     Beneficiary Designations. The Executive shall designate a
beneficiary by filing a written designation with the Company. The Executive may
revoke or modify the designation at any time by filing a new designation.
However, designations will only be effective if signed by the Executive and
received by the Company during the Executive's lifetime. The Executive's
beneficiary designation shall be deemed automatically revoked if all designated
beneficiaries (primary and contingent) predecease the Executive, or if the
Executive names a spouse as beneficiary (either primary or contingent) and the
marriage is subsequently dissolved. If the Executive dies without a valid
beneficiary designation, all payments shall be made to the Executive's estate.

        4.2     Facility of Payment. If a benefit is payable to a minor, to a
person declared incompetent, or to a person incapable of handling the
disposition of his or her property, the Company may pay such benefit to the
guardian, legal representative or person having the care or custody of such
minor, incompetent person or incapable person. The Company may require proof of
incompetence, minority or guardianship as it may deem appropriate prior to
distribution of the benefit. Such distribution shall completely discharge the
Company from all liability with respect to such benefit.

                                    ARTICLE 5
                               GENERAL LIMITATIONS

        to the claimant's claim for benefits.
