If an individual—
(1) has sustained disability compensable under section 8107(a) of this title;
(2) has filed a valid claim in his lifetime; and
(3) dies from a cause other than the injury before the end of the period specified by the schedule;
Payments under subsection (a) of this section, except for an amount payable for a period preceding the death of the individual, are at the basic rate of compensation for permanent disability specified by section 8107(a) of this title even if at the time of death the individual was entitled to the augmented rate specified by section 8110 of this title.
A surviving beneficiary under subsection (a) of this section, except one under subsection (a)(D)(v), does not have a vested right to payment and must be alive to receive payment.
A beneficiary under subsection (a) of this section, except one under subsection (a)(D)(v), ceases to be entitled to payment on the happening of an event which would terminate his right to compensation for death under section 8133 of this title. When that entitlement ceases, compensation remaining unpaid under subsection (a) of this section is payable to the surviving beneficiary in accordance with subsection (a) of this section.
