In addition to the penalties provided in title 18, United States Code, section 1001, any person guilty of any act, as provided therein, with respect to any matter under this Title, shall forfeit all rights under this Title, and, if payment shall have been made or granted, the Commission shall take such action as may be necessary to recover the same.

In connection with any claim decided by the Commission pursuant to this Title in which an award is made, the Commission may, upon the written request of the claimant or any attorney heretofore or hereafter employed by such claimant, determine and apportion the just and reasonable attorney's fees for services rendered with respect to such claim, but the total amount of the fees so determined in any case shall not exceed 10 per centum of the total amount paid pursuant to the award. Written evidence that the claimant and any such attorney have agreed to the amount of the attorney's fees shall be conclusive upon the Commission: Provided, however, That the total amount of the fees so agreed upon does not exceed 10 per centum of the total amount paid pursuant to the award. Any fee so determined shall be entered as a part of such award, and payment thereof shall be made by the Secretary of the Treasury by deducting the amount thereof from the total amount paid pursuant to the award. Any agreement to the contrary shall be unlawful and void. The Commission is authorized and directed to mail to each claimant in proceedings before the Commission notice of the provisions of this subsection. Whoever, in the United States or elsewhere, pays or offers to pay, or promises to pay, or receives on account of services rendered or to be rendered in connection with any such claim, compensation which, when added to any amount previously paid on account of such services, will exceed the amount of fees so determined by the Commission, shall be guilty of a misdemeanor, and, upon conviction thereof, shall be fined not more than $5000 or imprisoned not more than twelve months, or both, and if any such payment shall have been made or granted, the Commission shall take such action as may be necessary to recover the same, and, in addition thereto, any such person shall forfeit all rights under this title.
