                    Level 3 to Acquire Looking Glass Networks

             Level 3's Total Payments of $165 Million to Consist of
                 $87 Million in Shares of Level 3 Common Stock,
    $9 Million in Cash and $69 Million in Looking Glass Networks Liabilities

BROOMFIELD, Colo., June 5, 2006 -- Level 3 Communications, Inc. (Nasdaq: LVLT)
today announced that it has signed a definitive agreement to acquire Looking
Glass Networks, Inc., a privately held facilities-based provider of metropolitan
transport services. Level 3's payments in this transaction will total $165
million. Under the terms of the agreement, Level 3 will pay total consideration
to Looking Glass' security holders of $96 million, consisting of $87 million in
unregistered shares of Level 3 common stock and $9 million in cash. At closing,
Level 3 will also pay Looking Glass liabilities of approximately $69 million,
which are primarily senior secured debt.

Looking Glass, based in Oak Brook, Illinois, provides data transport services
including SONET/SDH, Wavelength and Ethernet as well as dark fiber and
carrier-neutral colocation. Looking Glass' network includes approximately 2,000
route miles serving 14 major metro markets, with lit fiber connectivity to
approximately 215 buildings. Looking Glass also has dark fiber connectivity to
approximately 250 additional buildings.

"The acquisition of Looking Glass will enhance our recently announced Level 3
Metro Services business unit," said Kevin O'Hara, president and chief operating
officer. "Looking Glass' metro expertise and proven ability to grow revenues
with high margins will be beneficial to the growth and expansion of our metro
business going forward."

"Looking Glass has a strong base of customers who buy a wide range of transport
services in the largest U.S. metro markets. We believe they will benefit greatly
from


the combination of our existing platform with the advanced capabilities and
reach of Level 3's broad network and services," said Lynn E. Refer, chief
executive officer of Looking Glass. "Our team is excited to play a key role in
Level 3's expanding metro services strategy and we look forward to continuing to
provide our customers with creative solutions when and where they need them."

The acquisition of Progress and ICG, and after close, of TelCove and Looking
Glass will increase the number of traffic aggregation points directly connected
to Level 3 fiber to approximately 5,100 in the U.S. and approximately 5,300
globally.

For the full year 2006, Looking Glass standalone is expected to generate
approximately $75 million to $80 million of annual revenue, approximately 25
percent higher than 2005's revenue. Looking Glass' gross margin in 2006 is
expected to be over 70 percent. On a standalone basis, Looking Glass is expected
to generate $5 million to $10 million of annual positive cash flow in 2006,
after approximately $12 million of capital expenditures and before net interest
expense. For 2007, Looking Glass is expected to contribute $20 million of
Adjusted OIBDA after integration expenses. Post integration annual cash flow is
expected to be approximately $30 million to $40 million.

Credit Suisse acted as sole financial advisor to Looking Glass. Kirkland &
Ellis, LLP acted as the company's legal advisor. Willkie Farr & Gallagher LLP
served as Level 3's legal advisor.

Closing is subject to customary conditions, including receipt of applicable
state and federal regulatory approvals. Closing is expected to occur in the
third quarter of 2006.

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 discounts and marketing funds from
software publishers; and reducing downward pressure of Software Spectrum's
margins as a result of the use of volume licensing and maintenance agreements.

Non-GAAP Metrics
Pursuant to Regulation G, the company is hereby providing a reconciliation of
non-GAAP financial metrics to the most directly comparable GAAP measure.

The company provides projections that include non-GAAP metrics that the company
deems relevant to management and investors. These non-GAAP metrics include
Adjusted OIBDA. The following reconciliation of this non-GAAP financial metric
to GAAP include forward-looking statements with respect to the information
identified as a projection. Level 3 has made a number of assumptions in
preparing our projections, including assumptions as to the components of
financial metrics. These assumptions, including dollar amounts of the various
components that comprise a financial metric, may or may not prove to be correct.
We caution you that these forward-looking statements are only predictions, which
are subject to risks and uncertainties including technological uncertainty,
financial variations, changes in the regulatory environment, industry growth and
trend predictions. Please see the company's Annual Report on Form 10-K for a
description of these risks and uncertainties.


In order to provide projections with respect to non-GAAP measures, we are
required to indicate a range for GAAP measures that are components of the
reconciliation of the non-GAAP metric. The provision of these ranges is in no
way meant to indicate that the company is explicitly or implicitly providing
projections on those GAAP components of the reconciliation. In order to
reconcile the non-GAAP financial metric to GAAP, the company has to use ranges
for the GAAP components that arithmetically add up to the non-GAAP financial
metric. While the company feels reasonably comfortable about the projections for
its non-GAAP financial metrics, it fully expects that the ranges used for the
GAAP components will vary from actual results. We will consider our projections
of non-GAAP financial metrics to be accurate if the specific non-GAAP metric is
met or exceeded, even if the GAAP components of the reconciliation are different
from those provided in an earlier reconciliation.

Adjusted OIBDA is defined as operating income from the consolidated condensed
statements of operations, plus depreciation and amortization plus non-cash
impairment charges plus non-cash stock compensation expense.

Management believes that Adjusted OIBDA is a relevant and useful metric to
provide to investors, as it is an important part of the company's internal
reporting and is an indicator of profitability and operating performance,
especially in a capital-intensive industry such as telecommunications.
Management also uses Adjusted OIBDA to compare the company's performance to that
of its competitors. Adjusted OIBDA excludes non-cash impairment charges and
non-cash stock compensation expense due to the company's adoption of the expense
recognition provisions of SFAS No. 123R. Additionally, Adjusted OIBDA excludes
interest expense and income tax expense and other gains/losses not included in
operating income. Excluding these items eliminates the expenses associated with
the company's capitalization and tax structures. Adjusted OIBDA excludes
depreciation and amortization expense in order to eliminate the impact of
capital investments which management believes should be evaluated through
consolidated free cash flow.


There are limitations to using non-GAAP financial measures, including the
difficulty associated with comparing companies that use similar performance
measures whose calculations may differ from the company's calculations.
Additionally, this financial measure does not include certain significant items
such as depreciation and amortization, interest expense and non-cash impairment
charges. Adjusted OIBDA should not be considered a substitute for other measures
of financial performance reported in accordance with GAAP.

The figures provided for depreciation and amortization in reconciling Adjusted
OIBDA with net earnings/loss are estimates and could vary significantly from the
depreciation and amortization costs determined after the company completes its
purchase price allocation in accordance with GAAP.
