DynamicWeb Selects Sun Microsystems' Workgroup Servers Running the Solaris 7 Software Environment to Power Its Business-To-Business E-Commerce Service.

MENLO PARK, Calif.--(BUSINESS WIRE)--Jan. 26, 1999--

Solaris 7 Expected To Drive Down Cost Of Providing Reliable,

Scalable Around-The-Clock E-Commerce Transactions

Sun Microsystems, Inc. today announced that its Solaris(TM) 7 software environment and Sun Enterprise(TM) 450 servers were chosen as the foundation for DynamicWeb Enterprises' (OTC BB:DWEB) EDIxchangeBuy business-to-business electronic commerce service that allows businesses to easily share documents and information over the Internet with their business partners. Price, performance and scalability are the primary reasons DynamicWeb tapped Sun as the platform of choice for all of its mission-critical business-to-business e-commerce services.

"Moving to the Sun platform is a competitive advantage for DynamicWeb and its customers," said Steve Vanechanos, Jr., chief executive officer of DynamicWeb. "The 64-bit capability of Solaris 7 means real gains in speed and capacity that will improve our price/performance ratio by giving us the scalability, reliability and security our customers need at a very competitive price."

DynamicWeb's electronic data interchange (EDI) services help businesses, their suppliers, and customers use the Internet to quickly and accurately exchange documents such as purchase orders and catalogs, and share information about order status and product availability. For smaller businesses that are not yet EDI-capable, DynamicWeb's services dramatically lower the costs of online document exchange, and enable them to work efficiently with larger industry partners. DynamicWeb customers, including Rite Aid, Inc. and Service Merchandise, Inc., use the EDIxchangeBuy service based on the Sun(TM) platform to automate the exchange of business documents with suppliers.

DynamicWeb's EDIxchangeBuy is designed to maximize the value of its customers' existing EDI infrastructures by managing all of the technical aspects of trading electronically with smaller suppliers. The suppliers need only a Web browser and Internet access to exchange business documents. DynamicWeb receives the documents sent by these trading partners, converts them to electronic files, and automatically sends them on to its customers' EDI systems.

As one of the leaders in the expanding Internet EDI market, scalability is a business-critical issue for DynamicWeb. "Success in our business is directly tied to fast, efficient handling of increasing volumes of transactions for a growing base of customers. With Solaris 7, Sun has pushed the envelope and come through with a proven, reliable operating environment that scales to meet the demands of Internet business," said Vanechanos.

According to the August 1998 'The Digital Commerce Marketplace: Adding Velocity to Vision' report, Dataquest predicts the EDI worldwide marketplace will grow from $40 million in 1998 to $550 million by 2000.

Solaris 7 Software Environment: A Solid Foundation for EDI

Solaris 7 software environment is ideal for high-capacity, real-time Internet applications like Internet EDI, because of its enormous increase in capacity, combined with the reliability for which the operating environment already has a long-standing reputation.

"E-commerce suppliers like DynamicWeb are showing the world that the Solaris 7 software environment is the foundation on which e-commerce will be built," said Brian Croll, director of marketing for Sun's Solaris Software. "With Solaris 7, Sun continues to be a leader among operating environments by providing customers with the power, speed, and reliability they need to achieve success in their business."

Delivering on its promise to make Solaris a premier operating environment for the network age, Sun unveiled its new Solaris 7 Operating Environment in October 1998. This next-generation, flagship software product is a highly scalable, reliable, 64-bit environment based on Internet standards. Running on both SPARC(TM) and Intel hardware, Solaris provides complete binary capability with previous releases of Solaris software, enhanced Windows NT interoperability, ease of administration, and mainframe-class capabilities.
