announced today that it has been advised that the staff of the Securities and

quarterly periods included in the fiscal year ended December 31, 2001. As
previously announced, the expected restatements involve revenue/sales credit
recognition, timing of expense recognition and non-cash lease accounting and

ABOUT METROMEDIA FIBER NETWORK
- ------------------------------

MFN is the leading provider of digital communications infrastructure solutions.
The Company combines the most extensive metropolitan area fiber network with a
global optical IP network, state-of-the-art data centers, award-winning managed
services and extensive peering relationships to deliver fully integrated,
outsourced communications solutions to Global 2000 companies. The all-fiber
infrastructure enables MFN customers to share vast amounts of information
internally and externally over private networks and a global IP backbone,
creating collaborative businesses that communicate at the speed of light.

Customers can take advantage of MFN's complete, end-to-end solution or select
individual components to complement their existing infrastructures. By leasing
MFN's metropolitan and regional fiber, customers can create their own, private
optical network with virtually unlimited, un-metered bandwidth at a fixed fee.
For more reliable, secure and high-performance Internet connectivity, customers
can use MFN's private IP network to communicate globally without ever touching
the public-switched network. Moreover, MFN's comprehensive managed services
enable companies to create a world-class Internet presence, optimize complex
sites and private optical networks, and transform legacy applications, all with
a single point of contact.

PAIX.net, Inc., a subsidiary of MFN and the original neutral Internet exchange,
offers secure, Class A co-location facilities where ISPs and other
Internet-centric companies can form public and private peering relationships
with each other, and have access to multiple telecommunications carriers for
circuits within each facility.

On May 20, 2002, Metromedia Fiber Network, Inc. and most of its domestic
subsidiaries commenced voluntary Chapter 11 cases in the United States
Bankruptcy Court for the Southern District of New York.

One network. One infrastructure. One source.
