LAS VEGAS--(BUSINESS WIRE)--April 23, 2001

Global Crossing Ltd. (NYSE:GX):

-- Live uncompressed (270 Mbps SDI) standard definition data will be broadcast
from London to Las Vegas and back.

-- Live signals from a digital camera in London to Las Vegas will also be
transmitted over the Global Crossing network.

Global Crossing Ltd. (NYSE:GX) today announced that it will feature live demonstrations of the company's ability to deliver compressed and uncompressed broadcast services using Global Crossing's fiber optic network at the National Association of Broadcasters (NAB) convention and exhibition this week in Las Vegas, Nevada.

The demonstrations, which will feature live uncompressed standard definition broadcast between Las Vegas and London and signals from a digital camera in London to Las Vegas, will showcase the new Global Crossing Media & Entertainment offering announced on April 18. The demonstrations will also highlight Global Crossing's network resiliency.

"Our seamless global fiber optic network, extending over 100,000 route miles, and connecting more than 200 cities when complete, will enable the media and entertainment industry to revolutionize the way it does business," said Donna Reeves, president, Global Crossing Media & Entertainment Markets. "Global Crossing now offers broadcasters quality equivalent to satellite transmission on a global basis, opening up new market opportunities and allowing them to unlock the value of their content. We are committed to provide the media and entertainment industry an efficient, super-high-speed optical fiber infrastructure for video transmission, content sharing, and real time collaboration on a global basis."

Global Crossing Media & Entertainment is offering services and solutions that will enable the media and entertainment industry to communicate and collaborate over the company's global broadband infrastructure. This includes in 2001 the development of a global media & entertainment extranet, enabling industry participants to exchange digital content over a secure, high-speed broadband infrastructure reaching five continents and over 200 cities. The extranet will connect geographically dispersed media facilities via the broadband exchange of TV-quality video, CD-quality audio, live event broadcasting, feature films and commercial production and on-demand applications.

Asia Global Crossing (Nasdaq:AGCX) earlier this year began offering commercial video transmission services, having successfully completed a test transmission of uncompressed HDTV and SDTV video between Japan and the U.S. using an STM-4C (622Mbps) on Pacific Crossing. The demonstration showcased the power of fiber optic cable to be less expensive, more reliable and a higher quality alternative to satellites for real-time video transmission. Asia Global Crossing, a publicly traded company whose largest shareholders include Global Crossing, Softbank, and Microsoft, provides the Asia Pacific region with a full range of integrated telecommunications and IP services.

"Using fiber optic cables instead of satellites, as evidenced by the recent tests by Asia Global Crossing and Global Access Ltd., will allow broadcasters to transmit HDTV and SDTV video signals without compression, thereby maintaining video quality in a way that is both more reliable and cost-effective than satellites," said John Legere, chief executive officer of Asia Global Crossing.

Currently, satellites are the most common medium used to transmit live video signals across the oceans, primarily because a satellite's footprint allows for "point-to-multipoint" distribution -- that is, a satellite can transmit data directly to receivers within a large geographical area. However, satellites can only transmit a limited amount of data. Typical standard-definition television (SDTV) signals require a 270Mbps data rate to achieve broadcast-quality output. But since a satellite's capacity is limited, SDTV video signals are commonly compressed to 45Mbps for transmission, which diminishes picture quality.

While satellites are preferred by programmers for point-to-multipoint delivery, Global Crossing's technology offers a more comprehensive and complementary solution for production and editing, contribution, interactive and live transmissions. In the future, as high-definition television (HDTV) becomes more prevalent and digital television the preferred standard, the point-to-multipoint benefit of satellite transmission may be negated by the quality loss inherent in satellite technology. Additionally, satellites are subject to weather-related outages, which impacts reliability. Fiber optic cables offer a more stable transmission solution.

Demonstrations will take place at Global Crossing's NAB booth at E3850 in the E-TOPIA hall at Sands Expo.
