of duties by the Grantee. 
 10.     Modification of Agreement. Any modification of this Award Agreement shall
be binding only if evidenced in writing and signed by an authorized representative of the Corporation, provided that no modification may, without the consent of the Grantee, adversely affect the rights of the Grantee hereunder.
