Business/Technology Editors

DALLAS--(BUSINESS WIRE)--May 2, 2000

Data Return Corporation, (NASDAQ: DRTN) a leading provider of managed hosting services for the Microsoft(R) Windows(R) 2000 platform, today announced they are partnering with Compaq (NYSE: CPQ) Professional Services to provide e-Procurement solutions for customers. Based on Commerce One's MarketSite Global Trading Portal, this hosted solution provides customers a range of e-commerce services from technology purchasing to auctions.

Compaq Professional Services elected to partner with Data Return due to the Company's expertise in deploying and managing Windows 2000 based e-commerce applications and its high-availability network and security architecture. With complete network redundancy including Compaq's NIC teaming technology, Data Return's high availability architecture allows switching infrastructure to be taken off-line without impacting the overall availability of the customer's application. In addition, Compaq and Data Return's solution incorporates ServiceGuard - a high availability managed firewall service that provides increased security for customer orders and other confidential company information.

"By selecting Data Return as a solution partner, Compaq Professional Services can focus on helping customers that would like to deploy these e-Procurement services within their own enterprise," said Alan Zimmerle, Compaq's V.P., North America central region professional services. Compaq Professional Services' e-Procurement practice provides enterprise customers with turnkey implementation and support services including basic setup, training and ERP integration.

The e-Procurement solution that Data Return and Compaq offer allows customers to browse, order and receive custom pricing on a variety of products through a single front-end buying application. "This e-Procurement application is important to Data Return both as a complex hosting provider and as one of Compaq's strategic partners," said Sunny C. Vanderbeck, chairman and CEO for Data Return. "By streamlining the procurement process, Compaq and Data Return are reducing the time it takes to provision and deploy services for our customers' mission critical applications."
