    <footnotes>
        <footnote id="F1">The conversion covered by this footnote automatically occurred pursuant to the terms of the Company's Amended and Restated Certificate of Incorporation when certain Moelis &amp; Company Group LP Units (&quot;Group Units&quot;) were exchanged for Class A common stock by certain selling stockholders in connection with the Company's public offering closed on April 21, 2014.</footnote>
        <footnote id="F2">Each share of Class B common stock is convertible into approximately 0.00055 shares of Class A common stock in certain circumstances, including when and if certain holders of Group Units elect to exchange such units for Class A common stock. Such conversions of Class B common stock may often result in conversion into less than 1 share of Class A common stock and in such case in lieu of such fractional share, the Company will pay the holder (Partner Holdings) cash equal to the Value (as defined in the Company's Amended and Restated Certificate of Incorporation) of the fractional share of Class A common stock.</footnote>
