(1) Represents common units of limited partnership interest ("OP Units") in the Operating Partnership. The Issuer is the general partner of the Operating Partnership. OP Units are redeemable fourteen months from the Transaction Date for cash equal to the then-current market value of one share of common stock, or at the election of the Issuer, for shares of the Issuer's common stock on a one-for-one basis.
(2) This amendment to Form 4 is filed for the purpose of updating the number of OP Units reported in Table II, Items 5, 7 and 9, to (i) delete 91,276 OP Units reported as held by the Donald R. Rady Trust and (ii) delete 91,252 OP Units reported as held by the Margo Rady Trust, as Ernest Rady is no longer the trustee of either of such trusts, and (iii) to reflect the transfer of 125,669 OP Units originally reported as held directly by Ernest Rady, individual, to the Ernest Rady Trust U/D/T March 10, 1983 on July 8, 2013.
(3) The OP Units are exchangeable for common stock of the Issuer on a one-for-one basis.
(4) The OP Units were issued either pursuant to (1) contribution agreements with the Issuer or the Operating Partnership, pursuant to which Reporting Person contributed their interests in certain entities that directly or indirectly own properties, to the Issuer, the Operating Partnership or their respective subsidiaries, or (2) merger agreements, where certain entities (interests in which are directly or indirectly owned by the Reporting Person) that directly or indirectly own properties merged with and into the Issuer, the Operating Partnership or their respective subsidiaries. The value of the OP Units was $20.50 per share as of the Transaction Date, based on the price of the common stock of the Issuer at the time of the Issuer's initial public offering.
(5) Not Applicable.
(6) Amount includes (a) 9,720,409 OP Units held by Ernest Rady Trust U/D/T March 10, 1983, for which the Reporting Person is the trustee; (b) 5,107,577 OP Units held by American Assets, Inc., which is indirectly controlled by the Reporting Person; and (c) 2,004 OP Units held by Western Insurance Holdings, Inc., which is indirectly controlled by the Reporting Person.
