Exhibit 10.12

PREPAID FORWARD PURCHASE AND SALES AGREEMENT (RAIL TANK CARS) (this “Agreement”), dated as of January 15, 2015, between Hess Tank Cars II LLC, a Delaware limited liability company (“Buyer”), and Hess Corporation, a Delaware corporation (“Seller”).

WHEREAS, Seller is a party to that certain Tank Car Purchase Agreement (the “Manufacturing Agreement”) with National Steel Car Limited, a Canadian corporation (the “Manufacturer”), dated October 8, 2014, pursuant to which the Manufacturer has agreed to fabricate and deliver to Seller a total of 550 rail tank cars (the “Railcars”);

WHEREAS, in consideration for the Railcars, Seller has certain obligations to make payments to the Manufacturer from time to time as set forth in the Manufacturing Agreement (such payments, the “Future Cash Payments”);

WHEREAS, Seller expects to receive delivery of the Railcars according to the schedule set forth in the Manufacturing Agreement;

WHEREAS, Buyer has been provided a copy of the Manufacturing Agreement, together with all schedules and exhibits affixed thereto; and

WHEREAS, Seller desires to sell the Railcars to the Buyer, and Buyer desires to purchase the Railcars from Seller, in consideration for immediate payment in an amount equal to the expected present value of the Future Cash Payments, as more fully described herein.

NOW, THEREFORE, in consideration of the premises and the agreements herein contained and other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, Seller and Buyer hereby agree as follows:

Buyer agrees to purchase, and Seller agrees to sell and deliver, the Railcars pursuant to the terms and conditions of this Agreement.

The purchase price payable by Buyer to Seller for the Railcars shall be an amount equal to US$104,109,845 (the “Purchase Price”). Within five (5) business days after the execution date of this Agreement, Buyer shall deliver the Purchase Price to an account designated by Seller.

Buyer and Seller acknowledge that the Purchase Price was calculated by reference to (i) the expected timing and amount of all Future Cash Payments to be made by Seller to the Manufacturer under the Manufacturing Agreement, taking into account the inherent uncertainties in both timing and amount of such Future Cash Payments, and (ii) a discount rate intended to reflect Buyer’s foregone use of funds in the amount of the Purchase Price between the delivery of the Purchase Price to Seller pursuant to this Section 2 and Seller’s delivery of the Railcars to Buyer. For the avoidance of doubt, notwithstanding anything in the Manufacturing Agreement to the contrary, upon payment of the Purchase Price to Seller, Buyer shall have no obligation to pay any additional amounts with respect to the Railcars.

From time to time following the execution of this Agreement, Seller shall deliver the Railcars to Buyer as and when received by Seller from the Manufacturer. Seller and Buyer acknowledge that the first delivery of Railcars is expected during the 2015 calendar year. Delivery of the applicable Railcars to Buyer shall be made by Seller at the same location that delivery of the applicable Railcars is taken by Seller from the Manufacturer (each such location, the “Delivery Location”). Buyer and Seller agree that Seller’s delivery obligations under this Agreement shall be deemed to be satisfied if Seller directs Manufacturer to deliver the applicable Railcars directly to Buyer, and Manufacturer delivers such Railcars to Buyer, at the Delivery Location.

Title and risk of loss with respect to the applicable Railcars shall pass from Seller to Buyer or Buyer’s designee at such time as Buyer or Buyer’s designee takes possession of such Railcars at the applicable Delivery Location.

Seller warrants that it shall have, and shall transfer to Buyer, good title to the Railcars delivered hereunder and that such Railcars shall be delivered to Buyer free and clear of all liens, encumbrances and all applicable foreign, federal, state and local taxes. Buyer and Seller agree that Seller’s warranty of title hereunder shall be deemed to be satisfied if Seller directs Manufacturer to deliver the Railcars directly to Buyer and Manufacturer thereafter transfers good title to the Railcars to Buyer.
