        <footnote id="F2">The Parent Note was issued pursuant the Note Purchase and Exchange Agreement among the Issuer, certain stockholders of the Issuer and Parent (the &quot;NPA&quot;). The Parent Note will convert automatically into Common Stock and/or Preferred Stock (defined below), as applicable, upon the earlier of (i) the time that is immediately prior to the closing of the merger contemplated by the Agreement and Plan of Merger among Parent, WC SACD One Merger Sub, Inc. and the Issuer (the &quot;Merger Agreement&quot;), and (ii) the time that is immediately prior to consummation of a Superior Transaction (as defined in the NPA), and is convertible into Common Stock and/or Preferred Stock, as applicable, at the option of Parent at any time on or after (iii) the date on which closing of an Alternative Transaction (as defined in the NPA) occurs, (iv) a determination by the Issuer's Board of Directors that the Issuer is no longer pursuing a process to sell itself and (v) April 30, 2019 (each of (i)-(v), a &quot;Trigger Date&quot;).</footnote>
        <footnote id="F3">On or after any Trigger Date, the Parent Note is convertible into either (i) to the extent that the Issuer's Common Stock remains listed on the Nasdaq Stock Market and if such Trigger Date is prior to the date on which Issuer stockholder approval of the Parent Note becomes effective (such effectiveness date, the &quot;Stockholder Approval Date&quot;), an aggregate of 5,354,947 shares of Common Stock and 1,572,183 shares of Issuer 6.0% Series A Preferred Stock, par value $0.01 per share (&quot;Preferred Stock&quot;), which Preferred Stock will be convertible into shares of Common Stock on and after the Stockholder Approval Date, or (ii) if such Trigger Date is on or after the Stockholder Approval Date, an aggregate of 13,215,859 shares of Common Stock.
