(&quot;P66 PDI&quot;) and Phillips 66 Gulf Coast Pipeline LLC (&quot;P66 Pipeline&quot;), the Issuer acquired a pipeline interest from P66 Pipeline. The consideration paid by the Issuer included the assumption of a $34.8 million note payable to P66 Company that the Issuer immediately paid in full; 606,056 common units of the Issuer issued to P66 PDI; and 12,369 general partner units issued to the General Partner to maintain its 2% general partner interest in the Issuer.</footnote>
        <footnote id="F2">This Form 4 is filed jointly by Phillips 66 (&quot;PSX&quot;), P66 Company, and P66 PDI. P66 PDI, a direct wholly owned subsidiary of P66 Company, owns all of the outstanding membership interests in the General Partner. Accordingly, the General Partner is an indirect wholly owned subsidiary of both P66 Company and PSX. P66 Company and PSX may be deemed to indirectly own the securities of the Issuer directly held by the General Partner, but disclaim beneficial ownership except to the extent of their pecuniary interest therein.
