        <footnote id="F1">The undersigned is a participant in the Atlas Energy, Inc. (the &quot;Company&quot;) Assumed Long-Term Incentive Plan (&quot;Assumed Plan&quot;).  The undersigned received 500 phantom units under the Atlas Energy Resources, LLC (&quot;ATN&quot;) Long-Term Incentive Plan on March 23, 2009, which were exchanged for 580 phantom shares of the Company in connection with the merger of ATN into a wholly-owned subsidiary of the Company.  Each phantom share represents the right to receive, upon vesting, either one share of common stock of the Company or its then fair market value in cash.  The phantom shares in the Assumed Plan vest 25% per year and are receivable without additional consideration.</footnote>
