Nathan’s appealed both of the court’s findings with respect to SMG’s claims relating to the sale of Nathan’s proprietary seasonings to SMG and the amount of the Judgment (See Note M.2). In connection with this appeal, Nathan’s was required to provide security for the damages, and entered into a Blocked Deposit Account Control Agreement (“Blocked Account Agreement”) with SMG and Citibank, N.A. (the “Bank”). Nathan’s also entered into a Security Agreement with SMG (the “Security Agreement”), pursuant to which, Nathan’s granted SMG a security interest in the amounts on deposit in the Blocked Account at the Bank (the “Account”) in order to secure Nathan’s’ obligation to pay to the Judgment, together with post-judgment interest on such amount and costs incurred in connection with such amounts. Pursuant to the Blocked Account Agreement, Nathan’s had deposited a total of $6,009,000 into the Account which included an amount equal to the post-judgment interest (calculated at 9% per annum) and classified the amount of the Judgment along with the post-judgment interest as restricted cash in the accompanying balance sheet. Pursuant to the Blocked Account Agreement, Nathan’s had no right to withdraw amounts from the Account, until: (1) the Bank received written notice from SMG (a “Release Notice”) that (a) the Judgment, plus all applicable post-judgment interest, had been satisfied, (b) the Judgment has been reversed or the Judgment has been vacated and the matter remanded and that any subsequent motions or appeals have been resolved, (c) Nathan’s and SMG entered a fully-executed settlement agreement resolving the Judgment, or (d) SMG withdrew “Disposition Notice” (as defined below) or (2) the Bank has received a Disposition Notice and has acted in accordance with the Disposition Notice. SMG agreed to deliver a Release Notice to the Bank within five (5) business days following any of the events described in clauses (1), (a), (b) or (c) above, and was entitled to provide written notice (a “Disposition Notice”) to the Bank to distribute the amounts in the Account if either (i) the Judgment was affirmed and all appeals are exhausted, and the amount of the Judgment plus all applicable post-judgment interest was not satisfied by Nathan’s and paid to SMG within thirty (30) days of such affirmance or (ii) an Event of Default occurs under the Security Agreement. On July 24, 2013, $6,009,000, inclusive of all post-judgment interest, was withdrawn by SMG in full satisfaction of this matter.
