Subject to that restriction, the Committee shall have the sole discretion to interpret this Plan and to adopt rules and interpretation for the application and implementation of this Plan. The decisions and interpretations by the Committee shall be final and binding on all Participants. -3- IN WITNESS WHEREOF, Homestake Mining Company has adopted this Plan, effective January 1, 1990.
