        Additionally, pursuant to the provisions of the Ernest S. Rady Trust,
the Evelyn S. Rady Trust and the DHM Trust, Ernest S. Rady, as trustee, has the
power to sell, buy, retain, invest and reinvest the assets of these trusts,
which include the shares of the Issuer's Common Stock. Further, Ernest S. Rady,
the sole trustee of the Ernest S. Rady Trust ("Rady Trust"), transferred the
majority of the Rady Trust's equity interest in each of Memrad Holdings, Ltd.
("Memrad"), American Assets, Inc. ("AAI"), and CANPAC Enterprises, Ltd.
("CANPAC" and together with Memrad and AAI, collectively, the "Transfer
Companies") to a newly formed annuity trust ("Annuity Trust"). This equity
transfer was accomplished through the issuance of non-voting securities by each
of the Transfer Companies. Ernest S. Rady, as the sole trustee of the Rady
Trust, retained all voting shares of each Transfer Company and, thereby, the
right to vote and direct the investment of the shares of common stock of Issuer
held by each of the Transfer Companies. Further, Ernest Rady, as the sole
trustee of the Annuity Trust, may vote and direct the investment of the Annuity
Trust's assets. Under Rule 13d-3(a) of the Exchange Act of 1934, as amended
("Act"), Ernest S. Rady, as trustee of the Rady Trust, is, therefore, deemed to
be the indirect beneficial owner of all of the securities of Issuer owned by the
Transfer Companies. For continuity of reporting and for ease of comprehension of
this report, the reporting parties hereunder have consolidated the holdings of
the Rady Trust and the Annuity Trust, the sum of which is reported by the Rady
Trust on Exhibit A.
