The WorldCom Name Enters Canada With An Extensive Product Suite of Internet and Data Networking Solutions.

TORONTO - February 7, 2001 - WorldCom today announced that its wholly-owned Canadian subsidiary, UUNET Canada, has adopted the name of its parent company, WorldCom, effective immediately. In addition to changing its name to WorldCom Canada Ltd., the company will expand its focus to deliver a wider range of advanced data networking and digital solutions for business.

The Canadian subsidiary currently offers high-speed Internet access, Web hosting, and Virtual Private Networks but will soon introduce new products into its portfolio including solutions such as enterprise hosting, media streaming, Web Centres, and other advanced data and Internet products and services. The expanded product portfolio, along with the new name, will lead to increased public awareness of WorldCom Canada and greater recognition of its fast and reliable data and digital solutions for business.

"With the name change to WorldCom, our Canadian operations will benefit from a name that is widely recognized and has a global reputation as a leading communications company for the digital generation," said Bernard J. Ebbers, WorldCom president and CEO. "Business in Canada can now depend on a supplier that offers an extensive range of products to increase productivity and profitability through the Internet. These initiatives will lead to new opportunities and increased marketplace awareness of the value our company brings to the Internet space in Canada."

"I am very excited about adopting the WorldCom name and our expanded focus. With our new name, we can build on and leverage the well-established reputation of WorldCom, as an experienced provider of business-critical data networking solutions," said Tal Bevan, president of WorldCom's Canadian operations. "Not only can our customers continue to expect premium products and services to enhance their productivity over the Internet, but they can also benefit from a provider which offers a wide range of data networking solutions under a well-known name with a strong, global presence."

WorldCom Global IP Network
For more than 13 years, WorldCom's UUNET division has built its reputation on constructing one of the most rigorously-engineered and widely-deployed IP networks in the world -- delivering high-quality, innovative Internet services to businesses. Today WorldCom's IP network spans more than 2,500 Points of Presence across five continents with services offered in North America, South America, Europe, Asia and Australia.

As the leader in deploying scalable technology in its network, WorldCom offers the most reliable and robust Internet transmissions over high-bandwidth connections. Currently, the company deploys ATM switches in the network, which enable high-quality transmissions of traffic.

This year the company completed activating OC-48c in the Americas, and completed the deployment of STM-16 links throughout Europe. In March of last year, the company began the U.S. network upgrade to OC-192c or 10 gigabits per second, speeds with Multi Protocol Label Switching (MPLS) technology.

MPLS, one of the most advanced Internet technologies in the industry, will fulfill even higher demand and scale for Internet bandwidth and will support an easy upgrade path in Canada as WorldCom advances its global IP network there to OC-192c speeds in 2001.
