        <footnote id="F1">The Reporting Persons are the Co-Trustees of the Madelyne Victoria Trione Trust, Victor Henry David Trione Trust, The Sally Patricia Trione 1997 Irrevocable Trust, The Denise Catherine Trione 1997 Irrevocable Trust, and The Henry Mark Trione 1997 Irrevocable Trust (collectively, the &quot;Adult Children Trusts&quot;), which, in the aggregate, are the direct owners of 24,780,000 shares of Common Stock of the Issuer. As the Co-Trustees of each of the Adult Children Trusts, the Reporting Persons have voting and dispositive power over these shares and may be deemed to be the indirect beneficial owner of such shares under Rule 16a-1(a)(2) promulgated under the Securities Exchange Act of 1934.</footnote>
        <footnote id="F2">(Continued from footnote 1) However, neither of the Reporting Persons are beneficiaries of any of the Adult Children Trusts. Each of the Reporting Persons disclaims beneficial ownership of any of the Issuer's securities held directly by the Adult Children Trusts and have no pecuniary interest therein, and this report shall not be deemed an admission that either of the Reporting Persons is the beneficial owner of such securities for purposes of Section 16 or any other purpose.</footnote>
