Introductory Note

On July 16, 2014, PetroLogistics LP, a Delaware limited partnership (“PetroLogistics”), completed its previously announced merger (the “Merger”) with FHR Propylene, LLC, a Delaware limited liability company (“Merger Sub”) and subsidiary of Flint Hills Resources, LLC, a Delaware limited liability company (“New Parent”).   The merger was completed in accordance with the Agreement and Plan of Merger and Membership Interest Transfer Agreement, dated as of May 27, 2014 (the “Merger Agreement”), by and among New Parent, Merger Sub, PetroLogistics, PetroLogistics GP LLC, a Delaware limited liability company and general partner of PetroLogistics (“General Partner” and together with PetroLogistics, the “MLP Entities”), and Propylene Holdings LLC, a Delaware limited liability company (“GP Holdings”).  Pursuant to the Merger Agreement, Merger Sub merged with and into PetroLogistics with PetroLogistics surviving the Merger as an indirect subsidiary of New Parent.  The Merger and certain related transactions are described below.

ITEM 1.02           Termination of a Material Definitive Agreement.

Upon completion of the Merger, PetroLogistics caused PL Propylene LLC, a Delaware limited liability company and subsidiary of PetroLogistics (“PL Propylene”), to terminate the existing $170.0 million amended and restated credit agreement, dated as of March 28, 2013, among PL Propylene, as borrower, PetroLogistics, as parent, the lenders party thereto, co-arrangers named therein, and Morgan Stanley Senior Funding, Inc., as sole lead arranger, administrative agent, collateral agent and swingline lender (the “Prior Credit Facility”).  With proceeds of loans borrowed by PetroLogistics under the New Credit Facility (as defined below), all indebtedness, liabilities and obligations (other than contingent reimbursement and indemnification obligations for which a claim had not been made as of the termination date) were paid in full, and all commitments of the lenders to extend credit under the Prior Credit Facility were terminated in full. No prepayment or early termination penalties or premiums were incurred as a result of the termination of the Prior Credit Facility.

Prior to the Merger, Merger Sub entered into a $290.0 million unsecured revolving credit facility as the borrower with the lenders party thereto and FHR Liquidity Holdings I, LLC, as administrative agent (the “New Credit Facility”).  PetroLogistics (as successor by merger to Merger Sub) assumed the rights and obligations of Merger Sub under the New Credit Facility.  The New Credit Facility matures on July 1, 2020.  The lender under the New Credit Facility is an affiliate of New Parent.  The lender’s obligations under the New Credit Facility, including the obligations to extend credit, are guaranteed by New Parent.  The New Credit Facility is pari passu in right of payment with the outstanding 6.25% Senior Notes (the “Notes”) of PetroLogistics and PetroLogistics Finance Corp. (“Finance Corp.” and together with PetroLogistics, the “Issuers”).

The New Credit Facility accrues interest, at the election of the borrower, at an alternative base rate or based on LIBOR, in each case, plus an applicable margin.  In addition, the New Credit Facility also requires PetroLogistics to pay an unused commitment fee. The New Credit Facility contains customary affirmative and negative covenants and events of default for financings of this nature for investment grade borrowers.

ITEM 2.01           Completion of Acquisition or Disposition of Assets.

On July 16, 2014, the Merger was consummated and GP Holdings transferred to an indirect subsidiary of New Parent 100% of the issued and outstanding membership interests in General Partner (the “GP Equity Transfer”).

Upon the Merger and GP Equity Transfer becoming effective (the “Effective Time”), by virtue of the Merger and without any action on the part of the MLP Entities, (a) each equity interest in PetroLogistics representing a fractional part of the equity interests of all limited partners of PetroLogistics (each such equity interest, a “Common Unit”) issued and outstanding and owned by holders, other than the Sponsors and the Founding Unitholders (each as defined below), of Common Units (the “Public Unitholders”) immediately prior to the Effective Time was cancelled and converted automatically into the right to receive an amount in cash equal to $14.00, without interest and subject to any required withholding taxes (the “Public Merger Consideration”), and (b) each Common Unit issued and outstanding and owned by (i) YSOF Propylene Investor LLC, York Special Opportunities Fund AIV II, L.P., York Special Opportunities Fund (PIV-A), L.P., YSOF (PIV-B) SUB II, LLC, LG Propylene LLC, Lindsay Goldberg & Bessemer II AIV L.P., Lindsay Goldberg & Bessemer II-A AIV L.P., Lindsay

(collectively, the “Sponsors”), and (ii) David Lumpkins, Nathan Ticatch and a related family partnership and family trust (collectively, the “Founding Unitholders” and, together with the Sponsors and the Public Unitholders, the “Unitholders”) immediately prior to the Effective Time was cancelled and converted automatically into the right to receive an amount in cash equal to $12.00, without interest and subject to any required withholding taxes, in each case, upon the terms and subject to the conditions set forth in the Merger Agreement. No additional consideration was delivered in exchange for the GP Equity Transfer.

In addition, a one-time cash distribution of $0.40 per Common Unit, payable to the Unitholders of record on the day preceding the closing date of the Merger, was declared and made in accordance with the provisions of the Merger Agreement (the “Merger Related Distribution”).

Also as of the Effective Time, each phantom unit granted pursuant to the PetroLogistics Long Term Incentive Plan, adopted May 4, 2012 (collectively, the “Phantom Units”), outstanding as of immediately prior to the Effective Time, whether or not vested, (i) was canceled and converted into the right to receive from New Parent (through General Partner) an amount of cash equal to the Public Merger Consideration plus the Merger Related Distribution for each Phantom Unit that was issued and outstanding (the “Phantom Unit Consideration”), (ii) is no longer outstanding, and (iii) ceased to exist.  Following the Effective Time, New Parent will cause the General Partner to pay the Phantom Unit Consideration to each holder of Phantom Units, upon the terms and subject to the conditions set forth in the Merger Agreement, in full satisfaction of all rights pertaining to the Phantom Units formerly outstanding.

No dissenters’ or appraisal rights were available, or will be available, with respect to the transactions contemplated by the Merger Agreement.

ITEM 3.01           Notice of Delisting or Failure to Satisfy a Continued Delisting Rule or Standard; Transfer of Listing.

On July 16, 2014, in connection with completion of the Merger, PetroLogistics notified the New York Stock Exchange (the “NYSE”) of its intent to remove the Common Units from listing on the NYSE and requested that the NYSE file with the Securities and Exchange Commission (the “SEC”) an application on Form 25 to delist and deregister the Common Units under Section 12(b) of the Securities Exchange Act of 1934 (the “Exchange Act”). On July 16, 2014, the NYSE filed the Form 25 with the SEC. In addition, on July 16, 2014, PetroLogistics filed with the SEC a Form 15 with respect to the Notes, requesting that reporting obligations of the Issuers and PL Propylene under applicable provisions of the Exchange Act with respect to the Notes be suspended.  In accordance with the terms of the Indenture governing the Notes (the “Indenture”), PetroLogistics will continue to file reports with the SEC.  PetroLogistics intends to subsequently file with the SEC a Form 15 with respect to the Common Units.
