                                   Exhibit A

The Participant's beneficiary shall be the person or persons designated by the
Participant on the beneficiary designation form provided by and filed with the
Committee or its designee. If the Participant does not designate a beneficiary,
the beneficiary shall be his Surviving Spouse or Civil Union Partner as defined
by the state of Vermont. If the Participant does not designate a beneficiary
and has no Surviving Spouse/Civil Union Partner, the beneficiary shall be the
Participant's estate. The designation of a beneficiary may be changed or
revoked only by filing a new beneficiary designation form with the Committee or
its designee. If a beneficiary (the "primary beneficiary") is receiving or is
entitled to receive payments under the Plan and dies before receiving all of
the payments due him, the balance to which he is entitled shall be paid to the
contingent beneficiary, if any, named in the Participant's current beneficiary
designation form. If there is no contingent beneficiary, the balance shall be
paid to the estate of the primary beneficiary. Any beneficiary may disclaim all
or any part of any benefit to which such beneficiary shall be entitled
hereunder by filing a written disclaimer with the Committee before payment of
such benefit is to be made. Such a disclaimer shall be made in a form
satisfactory to the Committee and shall be irrevocable when filed. Any benefit
disclaimed shall be payable from the Plan in the same manner as if the
beneficiary who filed the disclaimer had predeceased the Participant.
