Gulf Oil Adds Wright Express Affinity Program to Offerings Branded Card

Market Wire, April, 2006

Gulf Oil and Wright Express have entered into an agreement to offer flexible pricing to Gulf commercial customers at their locations, through a new, Gulf co-branded Affinity card program. Wright Express Corporation (NYSE: WXS), a leading provider of payment processing and information management services to the U.S. commercial and government fleet industry, developed the program for Gulf.

The program features the full functionality of a universally accepted Affinity program, enhanced with pricing options that include cost plus volume based contract pricing and discounts at Gulf locations. These customizable options provide commercial accounts and fleets powerful new tools and expanded acceptance to manage their vehicle related costs.

"We are delighted to be able to offer what we believe to be innovative and valuable pricing options for our corporate and large fleet customers," said CEO and President, Joe Petrowski. "This is another step in the direction of not only providing consistent supply of quality petroleum products, but additional brand services that will keep Gulf Oil in the forefront of customer service."
