        <footnote id="F1">These Common Units were acquired by a trust controlled by the Reporting Person in connection with the redemption by such trust of its membership units of Energy Realty Partners, LLC, the entity which previously owned such units.  This transaction only changes the nature of the Reporting Person's beneficial ownership.</footnote>
        <footnote id="F2">These Subordinated Units were donated to a foundation by a trust, the trustee of which is the Reporting Person.</footnote>
        <footnote id="F3">The Subordinated Units will convert into Common Units on a one-for-one basis at the end of the &quot;Subordination Period&quot; (as defined in the Issuer's First Amended and Restated Agreement of Limited Partnership, which was attached as Exhibit 3.1 to the Current Report on Form 8-K filed with the SEC by the Issuer on October 30, 2012).</footnote>
        <footnote id="F4">The number of Subordinated Units reported on this Form 5 corrects the number of Subordinated Units previously reported.  The correction is due to an adjustment of the beneficial ownership of the Reporting Person's Subordinated Units in connection with the initial public offering of the Issuer as previously reported in Footnote 9 to Item 12 in the Issuer's Form 10-K, filed on March 28, 2013, with the SEC.  These Subordinated Units were acquired by a trust controlled by the Reporting Person in connection with the redemption by such trust of its membership units of Energy Realty Partners, LLC, Lehigh Gas Corporation, Kimber Petroleum Corporation, and ERNJ, LLC, all of which entities previously owned such units.</footnote>
