        <footnote id="F1">Award of restricted stock units under the Cousins Properties Incorporated (CPI) 2005 Restricted Stock Unit Plan, as amended.  Each unit represents a right to receive a payment in cash equal to the fair market value of one share of CPI's common stock as of the date payment is due under the Plan.  These units will vest 25% per year on each anniversary date of the grant, with units being 100% vested in year 4 of the grant term.  While the shares are being held prior to vesting, the reporting person will have the right to receive all cash dividends but will not have shareholder rights.  All unvested shares will forfeit if the Director's service as a member of the CPI Board of Directors terminates, unless separation is due to death or change in control.</footnote>
