AT&T Selected by Enbridge to Deliver Advanced IP-VPN to Increase Network Security, Stability and Reliability

Houston, Texas, May 1, 2006

AT&T Inc. (NYSE:T) today announced that it has won a three-year $9 million networking contract from Enbridge Midcoast Energy, L.P., an indirect subsidiary of Enbridge, Inc. (NYSE/TSX: ENB), to integrate an advanced Internet Protocol Virtual Private Network (IP VPN) solution. Enbridge is a leader in energy transportation and distribution in North America and around the world.

The agreement renews and expands a long-standing relationship between the two companies and also provides Enbridge with significant savings for these services.

AT&T's global networking platform will incorporate AT&T's Multiprotocol Label Switching (MPLS) technology, connecting more than 225 Enbridge sites across the United States and Canada. AT&T's MPLS network includes more than 1,500 nodes with service availability in more than 127 countries.

The AT&T solution enables Enbridge employees to easily and securely access data and applications residing on a particular server, providing Enbridge's staff access to real-time information about the natural gas, crude oil, natural gas liquids and other liquid hydrocarbons flowing through their pipelines.

"We transport more than 2 million barrels of liquid hydrocarbons each day across North America and each day deliver about 5 billion cubic feet of natural gas, so it is critical that we have real-time access to accurate information," said Ben Backor, director of transportation services and information systems at Enbridge's Houston office. "AT&T's networking solutions provide the security, stability and reliability we expect and the service and value we demand."

In addition to enabling more effective communications between Enbridge's Houston office and its hundreds of field locations throughout North America, the AT&T solution will provide secure high-speed connectivity for fast and easy access to company databases and online applications.

AT&T also provides Enbridge with video and audio conferencing, domestic and international long distance and toll-free services.
