10.1 In General. Each Award shall be evidenced by an Award Agreement that shall include such provisions as the Committee shall determine and that shall specify:
10.2 Severance from Service. Each Award Agreement shall set forth the extent to which the Participant shall have rights, if any, under the Award following the Participants severance from service with the Company and its Subsidiaries. The Award Agreement may make distinctions based on the reason for the Participants severance from service and may contain obligations that apply beyond the term of the Award Agreement.
10.3 Restrictions on Transferability. Subject to the provisions of the Plan, in the case of an ISO (and in the case of any other Award), a Participants Award may not be sold, transferred, pledged, assigned, or otherwise alienated or hypothecated, other than by will or by the laws of descent and distribution, and shall be exercisable during the Participants lifetime only by the Participant.
10.4 Uniformity Not Required. The provisions of the Award Agreements need not be uniform among all Awards, among all Awards of the same type, among all Awards granted to the same Participant, or among all Awards granted at the same time.
