Following the forfeiture or settlement in shares of Stock of all Award Agreements outstanding as of September 5, 2018 and all Award Agreement issued under the Plan with respect to 2018 Salary Reduction elections, the Plan shall automatically terminate and the number of authorized shares of Stock remaining unissued under this Section 5 will be reduced to zero.

(b)    A Participant who is awarded Restricted Stock will not be issued a stock certificate in respect of such shares of Restricted Stock, but rather such issuance shall be maintained in a “book entry” (i.e., a computerized or manual entry) made in the records of the Company to evidence an award of shares of Restricted Stock to a Participant. Such Company records shall, absent manifest error, be binding on the Participants. A Participant who is awarded Restricted Stock Units will not be issued shares at the time such award is granted.
