HOLLY CORPORATION, HOLLY ENERGY PARTNERS AND ENBRIDGE ANNOUNCE SALT LAKE CITY CRUDE PIPELINE PROJECT

July 7, 2005
HOLLY CORPORATION, HOLLY ENERGY PARTNERS AND ENBRIDGE ANNOUNCE SALT LAKE CITY CRUDE PIPELINE PROJECT DALLAS, Holly Corporation (NYSE: HOC), Holly Energy Partners (NYSE: HEP), and Enbridge Inc. (TSX:ENB) (NYSE:ENB) announced today that the companies are working together to study the construction of a new crude oil pipeline from southwestern Wyoming to Holly’s Woods Cross refinery near Salt Lake City, Utah. When completed, the pipeline will remedy crude oil supply constraints that Holly and other local refiners are currently experiencing, especially for heavier Canadian crude oil varieties.

The pipeline will originate near Evanston, Wyoming, at the terminus of Frontier Pipeline – of which Enbridge is the majority owner – and terminate near Holly’s refinery in Woods Cross, Utah. The permit work for pipeline construction and operation is currently underway with construction projected to begin as early as the second quarter of 2006. To date, Willbros Engineers SLC has assisted in pipeline route selection and design.

Matthew P. Clifton, President of Holly Corporation and Chairman and CEO of Holly Energy Partners, said, “Having access to the right grades and quantities of crude oil for our Woods Cross refinery strengthens Holly’s capability to cost effectively satisfy the growing gasoline, diesel and jet fuel needs of Salt Lake City and the surrounding area for many years to come. Holly and Holly Energy look forward to working with Enbridge on a new pipeline to accomplish our crude supply objectives.”
