(1) On January 15, 2007 (Grant Date), Mr. Nelsen was awarded the right to receive these common shares of beneficial interest (Restricted Shares). These unvested Restricted Shares will vest and be issued subject to the following schedule: 50% time vesting in four equal parts commencing on January 6, 2008 and on each anniversary thereof; 50% time and benchmark vesting in four equal parts commencing on January 6, 2008 and on each anniversary thereof. The dividend will not be paid until the Restricted Shares have vested but there will be a catch-up payment upon vesting from the Grant Date to the applicable vesting date. No voting until vesting.
(2) On January 15, 2007 (Grant Date), Mr. Nelsen was awarded these common shares of beneficial interest (Restricted Shares). These unvested Restricted Shares will vest on time vesting only subject to the following schedule: 30% on January 6, 2008 and 35% each on January 6, 2009 and January 6, 2010. These Restricted Shares carry dividend and voting rights prior to vesting.
(3) This total includes (i) 4,664 vested Shares and (ii) 26,067 unvested Restricted Shares issued to Mr. Nelsen through January 15, 2007 (as well as the sale/cancellation of 3,369 shares).
(4) On January 15, 2007 (Grant Date), Mr. Nelsen was awarded these restricted limited partnership units in Acadia Realty Limited Partnership (LTIP Units) which vest in the same manner as Restricted Shares under footnote No. 1. Distributions will be payable currently and, after vesting and the revaluation (Book Up) of the book capital accounts of the holders of all of the common limited partnership units in Acadia Realty Limited Partnership (OP Units) will be exchangeable on a 1:1 basis for common OP Units which, in turn, are exchangeable on a 1:1 basis for common shares of beneficial interest.
