                        Level 3 Completes ICG Acquisition

                 Level 3 Pays Total Consideration of 25,975,088
      Shares of Level 3 Common Stock and Approximately $45 Million in Cash

BROOMFIELD, Colo., May 31, 2006 -- Level 3 Communications, Inc. (Nasdaq: LVLT)
today announced that it has completed its acquisition of all of the stock of ICG
Communications, Inc., a privately held Colorado-based telecommunications
company. Pursuant to the purchase agreement dated April 14, 2006, Level 3 paid
total consideration of 25,975,088 unregistered shares of Level 3 common stock
and approximately $45 million in cash.

Pursuant to the purchase agreement signed by Level 3 and ICG on April 14, 2006,
Level 3's cash consideration at closing was increased from the previously
announced amount of $36 million to reflect an improvement in ICG's working
capital, and is subject to adjustment based on the subsequent calculation of
actual closing date working capital.

"We are pleased to have completed the transaction, which gives Level 3 the
opportunity to further expand our footprint into areas where we see demand for
our services," said Kevin O'Hara, president and chief operating officer of Level
3. "ICG's business model fits nicely with the expansion of our metropolitan
services offerings."

ICG primarily provides transport, IP and voice services to wireline and wireless
carriers, Internet service providers and enterprise customers. ICG's network has
over 2,000 metro and regional fiber miles in Colorado and Ohio and includes
approximately 500 points of presence. ICG serves more than 1,600 customers.




Pursuant to the agreement, Level 3 did not acquire ICG's investments in New
Global Telecom or Mpower Holding Corporation. As a result of the transaction,
ICG is a wholly owned subsidiary of Level 3.

Forward-Looking Statement
Some of the statements made by Level 3 in this press release are forward-looking
in nature. Actual results may differ materially from those projected in
forward-looking statements. Level 3 believes that its primary risk factors
include, but are not limited to: increasing the volume of traffic on Level 3's
network; developing new products and services that meet customer demands and
generate acceptable margins; successfully completing commercial testing of new
technology and information systems to support new products and services,
including voice transmission services; stabilizing or reducing the rate of price
compression on certain of our communications services; integrating strategic
acquisitions; attracting and retaining qualified management and other personnel;
ability to meet all of the terms and conditions of our debt obligations;
overcoming Software Spectrum's reliance on financial incentives, volume

licensing and maintenance agreements. Additional information concerning these
