Item 1.01 |  | Entry into a Material Definitive Agreement.

Amended and Restated Trucking Transportation Services Agreement
In April 2011, Tesoro Logistics LP (the “Partnership”) reported that its wholly owned subsidiary, Tesoro Logistics Operations LLC (the “Operating Company”) had entered into a Trucking Transportation Services Agreement (the “Original Agreement”) with Tesoro Refining and Marketing Company (“TRMC”). On December 2, 2011, the Operating Company and TRMC entered into an Amended and Restated Trucking Transportation Services Agreement (the “Amended Agreement”). The Amended Agreement, which becomes effective January 1, 2012, extends the expiration of the initial term from April 30, 2013 to April 30, 2016. In addition, the Amended Agreement provides for one optional renewal term of five years.
The Amended Agreement provides that the Operating Company will continue to coordinate the collection, transportation and delivery of crude oil acquired by TRMC in Montana and North Dakota and intended for delivery by truck into the Company's High Plains pipeline system, but extends the scope to include any other destinations (including third party destinations) in Montana and North Dakota.
In exchange for these services, TRMC pays a fee and agrees to certain minimum volume requirements. The Original Agreement provided for per-barrel transportation fees, but the Amended Agreement provides for a mileage-based trucking rate composed of a dispatch fee component and a mileage rate component with the total trucking fee per barrel on individual loads initially ranging from $2.00 per barrel to $5.21 per barrel depending on volume and length of haul. The Operating Company will also continue to charge TRMC separate uncommitted tank usage fees of approximately $0.15 per barrel on each barrel that is delivered by truck to the Operating Company's proprietary tanks and related truck unloading facilities located adjacent to injection points along the Company's High Plains pipeline system.
The Original Agreement obligated TRMC to use the Operating Company's trucking services for a minimum volume of crude oil equal to an average of 22,000 bpd per month. The Amended Agreement provides for changes in such minimum volume commitment as follows: (1) a reduction of 1,500 bpd upon the completion of the Company's new gathering pipeline from the High Plains System Connelly Station to the Marathon Connelly Hub, (2) an increase of 5,000 bpd beginning in April 2012, and (3) an additional increase of 5,000 bpd beginning in April 2013.
If TRMC fails to use the Operating Company to gather, transport and deliver an amount of crude oil equal to its minimum throughput commitment during any calendar month, then TRMC will pay the Operating Company a shortfall payment equal to the volume of the shortfall multiplied by an initial rate of $2.90 per barrel. The amount of any shortfall payment paid by TRMC will be credited against any amounts owed by TRMC for volumes the Operating Company gathers, transports and delivers in excess of TRMC's minimum throughput commitment during any of the succeeding three months.
The foregoing description is not complete and is qualified in its entirety by reference to the Trucking Transportation Services Agreement, which is filed as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated herein by reference.
