Tesoro Corporation announced that it has secured the rights from ExxonMobil to use the Exxon and Mobil brands at retail stations in Northern California, Oregon, Western Washington and Nevada, marketing areas strategically aligned with the Company's West Coast operations. Tesoro also secured the rights to use the Exxon and Mobil brands throughout Minnesota, Central/Eastern North Dakota and Northeastern South Dakota, marketing areas anchored by the Company's refinery in Mandan, North Dakota. Through this arrangement, Tesoro intends to assume ownership of branded-wholesale supply contracts for 54 Exxon- or Mobil-branded retail stations in Minnesota.

"Introducing the well-established Exxon and Mobil brands into our retail network will allow us to drive further integration between our refining and marketing businesses with brands known for their quality products and marketing programs," said Dan Romasko, Executive Vice President of Operations.

"This agreement with Tesoro provides consumers the opportunity to benefit from the reliability of supply from Tesoro along with the strength of the Exxon and Mobil brands," said John Rhodes, Americas Retail Director for ExxonMobil. "I am looking forward to working with Tesoro and to the opportunity to expand ExxonMobil's brand presence in multiple states."

The Minnesota contracts are expected to be transitioned to Tesoro by the end of 2013, with subsequent market launches expected to begin in 2014.
