WorldCom introduces industry's most comprehensive managed Web hosting packages in Canada.

Array of 18 new WorldCom Hosting Solutions enable any business to expedite go-to-market e-business plans.

TORONTO, June 4, 2001 - WorldCom (Nasdaq: WCOM), the leading global business data and Internet communications provider, today announced the introduction of the industry's most comprehensive set of managed Web hosting solutions in Canada. Available immediately, WorldCom-Canada is offering 18 different packaged hosting solutions designed to meet every company's need for high-performance global Web hosting services. The offerings bring together all the essentials of hosted e-business solutions - hosting, security, reporting, administration, monitoring and back-up - and advanced services that allow virtually any business to implement or improve its e-business strategy in as few as 10 to 15 days.

"WorldCom is demystifying what was a time-consuming and complex purchasing process," said Ron McMurtrie, vice president of E-Services for WorldCom. "In the past, it was hard for customers to compare services between providers and understand exactly what they were getting. WorldCom's packaged hosting solutions simplify that process, allowing companies to expedite their e-business strategies, regardless of scale, with unmatched efficiency, security and reliability."

Managed hosting has traditionally been limited to technically challenging custom-built solutions which can lead to a costly and lengthy sales and go-to-market process of four to six months. With these new packages, WorldCom is able to reduce the time, cost, technical issues and sales cycles associated with deploying a managed hosting solution to jumpstart a customer's e-business plans.

By combining the most popular and commonly used Web hosting platforms and applications with industry-leading Service Level Agreement (SLA) guarantees and connectivity to its award-winning global IP network, WorldCom can quickly and effectively address the reliability, Web hosting performance, scalability and security needs of global businesses of all sizes. WorldCom's newest offerings are now available in markets across the United States and Canada and will be globally deployed in Europe and Asia Pacific in 2001.

"When it comes to Web sites and Web-based applications, customers expect uncompromising availability 24-by-7," said Tal Bevan, president of WorldCom Canada. "Businesses can meet those expectations with WorldCom's managed Web hosting solutions - ensuring optimal Web site performance for mission-critical applications and high levels of site availability with access to the most reliable and extensive global IP network in the world."

According to a recent global Web hosting survey done by analyst and consulting company, Ovum, the global managed hosting market will increase in value from $4.7 billion in 2001 to just over $27 billion in 2006, thus accounting for 56 percent of the Web hosting market.

"Pre-packaged offerings are part of the next evolution of the Web hosting market," said Courtney Quinn, senior analyst, The Yankee Group. "With its new portfolio of fully managed, productized Web hosting solutions that run over the company's high performance global IP network, WorldCom is positioning itself to be a leader in the market and to take advantage of the growing demand for these types of services."

Meeting the Hosting Needs of E-businesses
Leveraging the company's alliance with managed hosting services leader Digex and WorldCom's unrivaled global IP network, these newest offerings address six distinct levels of customer hosting needs - from a basic Web site to a high-end, high availability e-commerce site. Now WorldCom customers across North America have access to ready-to-use hosted e-business solutions whatever their needs, whether it's a simple Web site that provides general company information, or a site that offers online shopping functionality with personalized frequent shopper accounts.

The six hosting packages are available today on three platforms, Microsoft Windows NT, Windows 2000 and Solaris. Each of the six levels of hosting packages contain hardware, software, Internet connectivity, support and industry-leading SLAs.
