BENEFICIARY DESIGNATION. You may name a beneficiary or beneficiaries to receive any DSUs and related dividend equivalents that vest before you die but are settled after you die. This may be done only on a Beneficiary Designation Form and by following the rules described in that Form. The Beneficiary Designation Form does not need to be completed now and is not required as a condition of receiving your Award. However, if you die without completing a Beneficiary Designation Form or if you do not complete that Form correctly, your beneficiary will be your surviving spouse or, if you do not have a surviving spouse, your estate.

10.02 Beneficiary Designation. Each Participant may name a Beneficiary or Beneficiaries (who may be named contingently or successively) to receive any Plan benefits that are unpaid at the Participants death. Each designation made will revoke all earlier designations made by the same Participant, must be made on a form prescribed by the Committee and will be effective only when filed in writing with the Committee. If a Participant has not made an effective Beneficiary designation, the deceased Participants Beneficiary will be his or her surviving spouse or, if there is no surviving spouse, the deceased Participants estate. The identity of a Participants designated Beneficiary will be based only on the information included in the latest beneficiary designation form completed by the Participant and will not be inferred from any other evidence.
