April 27, 2001

Apr. 27, 2001--Genuity Inc., a provider of Internet infrastructure services and eBusiness Network Platforms, announced enhancements to its Service Level Agreements (SLAs) for its dedicated U.S. Internet access customers.

Genuity Inc. (NASDAQ: GENU), a provider of Internet infrastructure services and eBusiness Network Platforms, announced enhancements to its Service Level Agreements (SLAs) for its dedicated U.S. Internet access customers. The company also announced the availability of an OC-48 (2.488Gbps) service that will provide large businesses and Internet Service Providers with unprecedented bandwidth.

Genuity's Tier 1 backbone, a 17,700-mile optical network, enables the company to offer enhanced SLAs and OC-48 service to meet increasing customer requirements. The network, which uses 10 gigabit-per-second (Gb/s) IP traffic running directly over fiber, is built to scale with customers as the businesses and applications they build require an ever-increasing amount of bandwidth.

Available immediately for all new and existing customers, Genuity has enhanced its domestic latency and packet loss provisions in its current SLA:

* Packet loss measurement is reduced from 1 percent to 0.5 percent (average per month),

* Network latency measure is reduced from 65msecs to 55msecs (average per month).

* Genuity's SLA also includes a 99.97% uptime guarantee.

The OC-48 service, which would exhaust the available bandwidth of most non-Tier-1 networks, is designed for both enterprise and wholesale customers that require high bandwidth capability. With OC-48 connectivity, customers can run large-scale applications and bandwidth intensive programs as well as expanding their own network coverage as a Tier 2 provider.

OC-48 is a level of bandwidth that will permit Genuity customers to build their network and business capabilities. To define the scale of an OC-48 (2.488Gbps) connection, it is equivalent to 48 DS3s, or 1,344 DS1s, or 32,256 DS0s (standard voice quality line).

Genuity's OC-48 offering includes a Direct Optical Cross-connect (DOC) process. DOC on OC-48 reduces local loop requirements that are often not met by telco providers, and provides customers direct access to Genuity's SONET infrastructure facilities.
