This Letter Agreement shall be governed by and construed in accordance with the laws of the State of Ohio applicable to agreements made and to

consent of Parent and the Company; provided, however, that if you die, all amounts then payable to you hereunder will be paid in accordance with the terms of this Letter Agreement to your devisee, legatee, or other designee, or if
there be no such designee, to your estate.
