(2) Pursuant to the terms of the Merger Agreement (as defined in the Remarks section), each share of the Issuer's Series A common stock was converted into the right to receive 0.580 of a share of Parent's (as defined in the Remarks section) Series C common stock.
(3) Includes distributions to the reporting person of: (a) 13,564 shares of Series A Cumulative Redeemable Preferred Stock previously reported as indirectly held by the grantor retained annuity trust; and (b) 581 shares of Series A Cumulative Redeemable Preferred Stock previously reported as indirectly held by the reporting person's 401(k) Savings Plan.
(4) Pursuant to the terms of the Merger Agreement, each share of the Issuer's Series A Cumulative Redeemable Preferred Stock was converted into the right to receive 1 share of Parent's newly issued Series A Cumulative Redeemable Preferred Stock.
(5) A limited liability company, of which the reporting person is the managing and sole member, has a 25% ownership interest in Missy, LLC; his spouse has a 25% ownership interest in Missy, LLC; and his adult daughter holds the remaining 50% ownership interest in Missy, LLC. Accordingly, the reporting person may be deemed to be the indirect beneficial owner of certain of the Issuer's securities owned by Missy, LLC. The reporting person disclaims beneficial ownership of these securities, except to the extent of his pecuniary interest therein.
(6) The reporting person disclaims beneficial ownership of these shares owned by his spouse.

The RSUs with respect to Parent's Series C common stock are subject to the same vesting, terms, restrictions and other conditions as those applicable to the corresponding Original RSU.
