Except as provided in this Section 6 , neither this Agreement, the Phantom Units nor the DERs granted hereunder may be sold, assigned, pledged, exchanged, hypothecated, or otherwise transferred, encumbered, or disposed of by the Employee. Notwithstanding the foregoing, if the Employee should die after a Phantom Unit has become a Vested Phantom Unit, but before such Vested Phantom Unit and corresponding DER have been settled, such Vested Phantom Unit and corresponding DER shall be subject to transfer by reason of the Employee’s death by will or the laws of descent and distribution. Any purported transfer, assignment, alienation, pledge, hypothecation, attachment, sale, transfer or encumbrance not in accordance with the foregoing shall be null, void and unenforceable against the Company Entities.
