Section 10. Limitation on Assignments.
Benefits under this Plan are not subject in any manner to anticipation, alienation, sale, transfer, assignment, pledge, encumbrance, attachment or garnishments by creditors of the Participant or the Participant's Beneficiary and any attempt to do so shall be void. Subject to Section 19 and notwithstanding the foregoing, upon receipt of a copy of a decree from a court of competent jurisdiction which finally declares a Participant's spouse as having property rights to a portion of the amounts credited to such Participant's Deferral Account, the Committee shall segregate such portion from the Participant's Deferral Account and hold that portion for the benefit of the spouse.
