(1) The grant of the Restricted Stock Units (RSUs) reported herein generally vest one-third per year from the date of award and entitle the Reporting Person to receive shares of the issuer common on either (i) the vesting of RSUs or (ii) upon the conclusion of such longer deferral period as the Reporting Person may elect in advance. In either occurrence (i) or (ii) the RSUs automatically convert into shares of common stock on a one for one basis at no conversion cost to the Reporting Person.
