Tesoro Logistics LP Closes the Acquisition of the Second Portion of the West Coast Logistics Assets from Tesoro Corporation

SAN ANTONIO - September 30, 2014 - Tesoro Corporation TSO ("Tesoro") and Tesoro Logistics LP TLLP (the "Partnership" or "TLLP") today announced that TLLP has closed the remaining portion of the acquisition of certain terminalling and pipeline assets (the "West Coast Logistics Assets") owned by Tesoro and certain of its subsidiaries. TLLP acquired Tesoro Alaska Pipeline Company LLC, which owns a refined products pipeline located in Alaska, for total cash consideration of $28.6 million, financed with borrowings under the Partnership's revolving credit facility.

The approximately 70 mile long refined products pipeline links TLLP's Anchorage, Alaska terminal to Tesoro's Kenai, Alaska refinery and the Kenai pipeline marine wharf. "The pipeline provides continued enhancement of our Western United States footprint," said Greg Goff, TLLP's Chairman and Chief Executive Officer.

In connection with the closing of the transaction, Tesoro and the Partnership entered into a throughput agreement for the pipeline, which includes a minimum throughput commitment.
