                          Announce Strategic Agreements

Bell Atlantic to Acquire $550 Million of Metromedia Fiber Network's
Fiber Optic Infrastructure and Invest $1.7 Billion in Company

Metromedia Fiber Network Announces Enhanced Network Build Out

NEW YORK-- Bell Atlantic (NYSE:BEL) and Metromedia Fiber Network, Inc.
(NASDAQ:MFNX) today announced a strategic agreement that will speed the
deployment of both Bell Atlantic's data services and Metromedia Fiber Network's
build out plan of its fiber optic infrastructure.

      Metromedia Fiber Network (MFN) is an international provider of dedicated
fiber optic networks in major metropolitan markets.

      Under an agreement valued at $550 million, MFN will provide dark fiber
infrastructure to Bell Atlantic for a twenty-year period at industry-leading
prices. The agreement will provide Bell Atlantic low-cost access to MFN's
networks in 50 major U.S. metropolitan markets and multiple cities
internationally via MFN's fiber optic infrastructure. Dark fiber is unlit fiber
optic strands that provide virtually unlimited bandwidth for the transmission of
data, voice, video and multi-media communications services.

      In addition, Bell Atlantic will invest about $700 million to purchase
approximately 9.9 percent of the equity of MFN through the purchase of newly
issued shares at $28 per share.

      Also, as part of the transaction, Bell Atlantic will buy approximately
$975 million in debt securities convertible into common stock at a conversion
price of $34 per share, increasing Bell Atlantic's potential equity investment
in MFN to about 19 percent of the company. MFN will use this new cash infusion
to accelerate the build out of its nationwide dark fiber infrastructure as well
as to enter new markets in the U.S. and internationally.


      "This relationship extends our data network and advances our strategy to
be a nationwide and global provider of leading-edge communications services,"
said Larry Babbio, president and chief operating officer of Bell Atlantic. " It
also complements the reach of the GTE national backbone network and our new
wireless venture with Vodafone. As a result, the combined Bell Atlantic/GTE will
have the capability to better serve its largest existing business customers on
both a regional and national basis."

      Howard Finkelstein, president of MFN, said, "We're very pleased that we
have broadened our relationship with Bell Atlantic. This agreement accelerates
the global expansion of our end-to-end pure photonic infrastructure, enabling us
to meet the sophisticated high bandwidth needs of our diverse carrier and
enterprise customer base. In addition, Bell Atlantic not only becomes a premier
customer, but an important anchor tenant."

      MFN's recent acquisition of AboveNet also provides additional potential
benefits to Bell Atlantic. AboveNet is a leading provider of high performance
Internet connectivity solutions that include more than 270 peering
relationships, proprietary technology and Internet infrastructure that enables
highly enhanced levels of service in the delivery of mission-critical Internet
applications.

      MFN has already announced planned networks covering 25 U.S. markets and
multiple international cities. In connection with this agreement, MFN is
announcing its intention to enter a total of 50 domestic markets and additional
international cities. The transaction also gives Bell Atlantic access to more
than 7,000 planned route miles in the United States and Europe.

      "The MFN facilities will enhance the merged Bell Atlantic/GTE
infrastructure and provide our existing large business customers the high
bandwidth services they require regionally and nationally," said Joe Farina,
president and chief executive officer of Bell Atlantic Data Solutions Group.
"This agreement also provides us with the flexibility to deploy capacity where
needed to meet our customers' needs."

      The commercial agreement with MFN is consistent with Bell Atlantic's
previously announced plans to build an in-region asynchronous transfer
mode-based long distance network. Bell Atlantic's Data Solutions Group has
already leased dark fiber from MFN in the New York area as part of the network
build out. Other Bell Atlantic business units also will benefit from this
agreement, including Bell Atlantic Mobile.

      Completion of this transaction is subject to the expiration of the
Hart-Scott-Rodino waiting period and certain state regulatory and other
approvals.
