Each participant shall file with the administrative service agency a written designation of one or more persons as the beneficiary who shall be entitled to receive the plan benefit, if any, payable under the plan upon his or her death. A participant may from time to time revoke or change his or her beneficiary designation without the consent of any prior beneficiary by filing a new written designation with the administrative service agency. The last such designation received by the administrative service agency "in good order" shall be controlling; provided, however, that no designation or change or revocation thereof shall be effective unless received by the administrative service agency in good order prior to the participant's death, and in no event shall it be effective as of a date prior to such receipt. For purposes of this Article IX, a beneficiary designation shall be deemed to be received in good order only if the administrative service agency can reasonably identify the beneficiary or beneficiaries named in the designation.
A. 
If no such beneficiary designation is in effect at the time of a participant's death, or if no designated beneficiary survives the participant, or if no designated beneficiary can be located with reasonable diligence by the administrative service agency, the payment of the plan benefit, if any, payable under the plan upon the participant's death shall be made by the Trustee from the Trust Fund to the participant's surviving spouse, if any, or if the participant has no surviving spouse, or the surviving spouse cannot be located with reasonable diligence by the administrative service agency, then to the deceased participant's estate. If the administrative service agency is in doubt as to the right or entitlement of any person to receive such amount, the administrative service agency shall inform the Committee and the Trustee, and the Trustee may retain such amount, without liability for any interest thereon, until the rights thereto are determined, or the Trustee may pay such amount into any court of appropriate jurisdiction or to any other person pursuant to applicable law and such payment shall be a complete discharge of the liability of the Trustee, plan, Committee, employer, administrative service agency and financial organizations.
B. 
If the beneficiary so designated by the participant dies after the death of the participant but prior to receiving a complete distribution of the amount that would have been paid to such beneficiary had such beneficiary's death not then occurred, then, for purposes of the plan, the distribution that would otherwise have been received by such beneficiary shall be paid to the beneficiary's estate.
Notwithstanding § 50-9.2, a beneficiary who is a surviving spouse of the participant may designate a subsequent beneficiary, subject to the same filing requirements of § 50-9.1, to the extent permitted under Section 401(a)(9) of the Code. To the extent such surviving spouse is not permitted or does not elect to designate a subsequent beneficiary pursuant to the preceding sentence, and the surviving spouse dies prior to receiving a complete distribution of the amount that would have been paid to such surviving spouse had such surviving spouse's death not then occurred, then, for purposes of the plan, the distribution that would otherwise have been received by such surviving spouse shall be paid to the surviving spouse's estate.
