Each of the Reporting Persons disclaims the existence of a "group" and disclaims beneficial ownership of the securities held by AD Holdings, LLC (and this report shall not be deemed an admission that any such person is the beneficial owner of such securities), except to the extent of such person's pecuniary interest therein, if any.
