Mr.&#160;Wild will also continue to be eligible for company-paid healthcare coverage for up to 18 months. Mr.&#160;Wild will remain subject to the restrictive covenants applicable to him, and a portion of the payments described above shall be repayable if he breaches those restrictive covenants. </p> <p style="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Except as provided herein, the disclosures contained in this Amendment No. 1&#160;have not been updated to reflect events, results or developments that have occurred since the filing of the Original Form <span style="white-space:nowrap">8-K.</span> This Amendment No.&#160;1&#160;should be read in conjunction with the Original Form <span style="white-space:nowrap">8-K,</span> which provides additional details of Mr.&#160;Wild&#8217;s appointment to the Board, severance payments and compensatory arrangements. </p>
