This document summarizes Level 3's safe harbor statement regarding forward-looking statements. It notes that some statements made in company presentations are forward-looking and subject to uncertainties outside the company's control. It identifies the most important risk factors as disruptions in financial markets, the company's ability to increase traffic and integrate acquisitions, develop new services, and meet debt obligations. Additional information on risk factors is available in Level 3's SEC filings. Statements should be evaluated in light of the important risk factors.

2. Safe Harbor Statement
Some of the statements made in this presentation are forward looking in nature. These
statements are based on management's current expectations or beliefs. These forward
looking statements are not a guarantee of performance and are subject to a number of
uncertainties and other factors, many of which are outside Level 3's control, which could
cause actual events to differ materially from those expressed or implied by the statements.
The most important factors that could prevent Level 3 from achieving its stated goals
include, but are not limited to, the current uncertainty in the global financial markets and the
global economy; disruptions in the financial markets that could affect Level 3's ability to
obtain additional financing; as well as the company's ability to: increase and maintain the
volume of traffic on the network; successfully integrate acquisitions; develop effective
business support systems; defend intellectual property and proprietary rights; manage
system and network failures or disruptions; develop new services that meet customer
demands and generate acceptable margins; adapt to rapid technological changes that lead
to further competition; attract and retain qualified management and other personnel; and
meet all of the terms and conditions of debt obligations. Additional information concerning
these and other important factors can be found within Level 3's filings with the Securities
and Exchange Commission. Statements in this presentation should be evaluated in light of
these important factors. Level 3 is under no obligation to, and expressly disclaims any such
obligation to, update or alter its forward-looking statements, whether as a result of new
