        <footnote id="F2">Under the terms of the contractual arrangements among the CCMP Capital Funds, CCMP Capital Associates and CCMP Capital (collectively, the &quot;CCMP Fund Entities&quot;), Mr. Murray is deemed to hold these shares for the benefit of the CCMP Fund Entities and must vote or dispose of such shares upon the direction of CCMP Capital. CCMP Capital is, therefore, deemed to indirectly beneficially own such shares. Mr. Murray disclaims beneficial ownership of the securities to the extent it exceeds his pecuniary interest therein and the inclusion of the shares in this report shall not be deemed to be an admission of beneficial ownership of the reported shares for the purposes of Section 16 or otherwise.</footnote>

(&#8220;CCMP Capital Investors&#8221;), (ii)&#160;CCMP Capital Investors (Cayman) II, L.P.

The actual pro rata portion of beneficial ownership of any shares held by the CCMP Capital Funds, CCMP Capital Associates, CCMP Capital Associates GP and CCMP Capital that may be deemed attributable to Mr.&#160;Murray is not readily determinable because it is subject to several variables, including the internal rate of return and vesting of interests within CCMP Capital Associates and the CCMP Capital Funds. Except for a de minimus pecuniary interest attributable to Generac Co-Invest GP, Mr. Murray has no pecuniary interest in the shares held by Generac Co-Invest.&#160; Mr.&#160;Murray disclaims beneficial ownership of all of the listed securities to the extent it exceeds his pecuniary interest therein and the inclusion of the shares in this report shall not be deemed to be an admission of beneficial ownership of the reported shares for the purposes of Section&#160;16 or otherwise.</font></div>
