Designation of Beneficiary.
(a) A participant may indicate in his or her subscription agreement, or may file a written designation of beneficiary with respect to, a person who is to receive any shares and cash, if any, from the participants account under the Plan in the event of such participants death subsequent to the end of the offering period but prior to delivery to him or her of such shares and cash. In addition, a participant may file a written designation of a beneficiary who is to receive any cash from the participants account under the Plan in the event of such participants death prior to the end of the offering period.
(b) Such designation of beneficiary may be changed by the participant at any time by written notice. In the event of the death of a participant and in the absence of a beneficiary validly designated under the Plan who is living at the time of such participants death, the Company shall deliver such shares and/or cash to the executor or administrator of the estate of the participant, or if no such executor or administrator has been appointed (to the knowledge of the Company), the Company, in its discretion, may deliver such shares and/or cash to the spouse or to any one or more dependents or relatives of the participant, or if no spouse, dependent or relative is known to the Company, then to such other person as the Company may designate.
