        <footnote id="F1">Holders of Class B common stock are not entitled to participate in any dividends or other distributions made by Silvercrest Asset Management Group Inc. (the &quot;Corporation&quot;) to holders of its capital stock (except for the right to receive par value upon the Corporation's liquidation or dissolution). Each Class B unit of Silvercrest L.P. is paired with a share of Class B common stock. Each share of Class B common stock entitles the holder to one (1) vote per share on all matters submitted to a vote of the Corporation's common stockholders. Shares of Class B common stock are not transferable unless transferred concurrently with the corresponding Class B unit and with the consent of the Corporation and Silvercrest L.P.</footnote>
        <footnote id="F2">Represents Class B units issued to the holder upon the vesting of deferred equity units and performance units. Silvercrest Asset Management Group LLC (&quot;SAMG LLC&quot;) awarded to its principals deferred equity units and performance units in 2009 and 2010 exercisable for cash or Class B units of Silvercrest L.P. Each deferred equity unit entitles the holder thereof to receive 100 Class B units of Silvercrest L.P. (and, as such, a corresponding number of Class B common stock of SAMG). SAMG LLC also granted to each employee who received an award of deferred equity units, a number of performance units which became exercisable for one (1) Class B unit for every two (2) Class B units issued upon vesting of the deferred equity units awarded to each principal in 2009 and 2010, subject to certain holding requirements as set forth in the unit award agreements.</footnote>
