Las Vegas -February 26, 2002 - PurchasePro (Nasdaq: PPRO) today announced that Unocal (NYSE: UCL), one of the world's leading independent natural gas and crude oil exploration and production companies, has adopted PurchasePro's e-Source technology as its global reverse auction platform.

Since initial implementation of the PurchasePro solution in July 2001, Unocal has used e-Source for reverse auctions in North America, Thailand, Singapore, Indonesia and the Philippines. To date, Unocal has conducted reverse auctions on commodities including marine gas oil and high-speed diesel oil, technology products such as video conferencing systems and computer equipment, and engineered equipment such as injection pump systems.

"Providing companies with highly scalable, strategic-sourcing solutions that offer significant returns on investment and savings is key to creating market share in this economy," said Chris Benyo, senior vice president, PurchasePro. "We believe that e-Source will enable any mid- to upper market organization to save as Unocal continues to save."

PurchasePro's sourcing process has been proven repeatedly throughout organizations worldwide, generating procurement efficiencies and price reductions that have resulted in hundreds of millions of dollars of savings. e-Source goes beyond reverse auctions and provides customers with a complete sourcing solution and automated procurement process, enabling buyers to quantify spend analysis, qualify additional suppliers, enhance RFI and RFQ management, cultivate competitive bidding and negotiations and manage supplier relationships more effectively than before.

Since PurchasePro began reporting monthly e-Source results in July 2001, 1,205 auctions have been conducted, totaling $691 million in high bids and $502 million in low bids, generating an implied savings of $189 million for companies worldwide.
