Yellow will participate in the design, functionality, and integration of The American Petroleum Exchange (www.AmericanPetroleumExchange.com).

"The Exchange gives us instant access to many of our fuel suppliers, shaving hours off our procurement process, while ensuring we meet our daily supply needs," said John Lehoczky, vice president and chief procurement officer for Yellow Corporation. "In addition, we will see significant savings in invoice processing costs."

Yellow is joined on The Exchange by United Parcel Service, Wal-Mart, Ryder Transportation, Tyson Foods, American Freightways, Federal Express Ground, The Pantry, and Moran Towing as "Charter Members." Combined, the charter members purchase over six billion gallons of fuel annually.

Auctions, reverse auctions, forward fixed and variable contracts, and indexed-based deals are available. Additional benefits of The Exchange include the option of using dynamic pricing tied to NYMEX quotes and other real-time and same-day indices.

The Exchange has received funding from UCG b2b Ventures, specialists in Internet business-to-business opportunities. Other fund investments include TechTarget.com , a portfolio of targeted hi-tech portals.
