(1) On June 18, 2012, the board of managers of PL Manufacturing LLC declared a distribution of 97,493,750 Common Units ("Common Units") representing limited partner interests in PetroLogistics LP (the "Issuer") to its members, including a distribution of 16,282,081 Common Units to the Reporting Person.
 
Remarks:
The Reporting Person may be deemed a "director by deputization" of the Issuer by the fact that Zalmie Jacobs serves as a director of the general partner of the Issuer as the designee of the Reporting Person. On March 30, 2012, the Issuer issued certain limited partnership interests to Propylene Holdings LLC in exchange for a capital contribution consisting of all of the equity of PL Propylene LLC, and thereafter, Propylene Holdings LLC distributed 1% of such limited partnership interests to its sole member PL Manufacturing LLC, which in turn distributed such limited partnership interests to its members, including the Reporting Person.  As a result of such distributions, on March 30, 2012, a 0.2% limited partnership interest (the "Limited Partner Interests") in the Issuer was distributed to the Reporting Person. On May 3, 2012, the limited partnership interests issued by the Issuer were recapitalized pursuant to the Amended and Restated Limited Partnership Agreement of the Issuer, dated as of May 3, 2012 (the "Limited Partnership Agreement").  Pursuant to the Limited Partnership Agreement, the Limited Partner Interests were reclassified into 275,000 Common Units, representing 0.2% of the issued and outstanding Common Units at such time. On May 9, 2012, the Common Units were registered under Section 12(b) of the Securities Exchange Act of 1934, as amended.
