Explanation of Responses:

( 1 )CVR Energy, Inc. ("CVI") directly beneficially owns 10,539,880 Shares. ( 2 )On March 19, 2020, CVI entered into a forward contract providing for the purchase by CVI of 372,000 Shares at a forward price of $9.00 per Share, plus a financing charge. In addition, as part of the purchase price for the Shares, CVI paid the counterparty to the forward contract $2.38 per Share upon establishing the contract. Subject to the rights of CVI to accelerate the settlement date, the forward contract will settle on March 18, 2022. ( 3 )The forward contract provides for physical settlement, with CVI retaining the right to elect cash settlement. The forward contract does not give CVI direct or indirect voting, investment or dispositive control over the Shares to which the contract relates. ( 4 )IEP Energy LLC ("IEP Energy") holds approximately 71% of the outstanding common stock of CVI. Icahn Enterprises Holdings L.P. ("Icahn Enterprises Holdings") is the sole member of Icahn Building LLC ("Building"), which is the sole stockholder of American Entertainment Properties Corp. ("AEP"), which is the sole member of IEP Energy Holding LLC ("Energy Holding"), which is the sole member of IEP Energy. Beckton Corp. ("Beckton") is the sole stockholder of Icahn Enterprises G.P. Inc. ("Icahn Enterprises GP"), which is the general partner of Icahn Enterprises Holdings. ( 5 )Beckton is 100 percent owned by Carl C. Icahn. In addition, Mr. Icahn is the indirect holder of approximately 92.0% of the outstanding depositary units representing limited partnership interests in Icahn Enterprises L.P. ("Icahn Enterprises"). Icahn Enterprises GP is the general partner of Icahn Enterprises, which is the sole limited partner of Icahn Enterprises Holdings. As such, Mr. Icahn is in a position indirectly to determine the investment and voting decisions made by CVI. ( 6 )Each of IEP Energy, Energy Holding, AEP, Building, Icahn Enterprises Holdings, Icahn Enterprises GP, Beckton and Mr. Icahn may be deemed to indirectly beneficially own (as that term is defined in Rule 13d-3 under the Act) the Shares which CVI directly beneficially owns. Each of IEP Energy, Energy Holding, AEP, Building, Icahn Enterprises Holdings, Icahn Enterprises GP, Beckton and Mr. Icahn disclaims beneficial ownership of such Shares except to the extent of their pecuniary interest therein.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.
