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.

Statements in this release should be evaluated in light of these important factors. - 30- 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. Projected Adjusted OIBDA Post-acquisition 2007 Twelve Months Ended December 31, 2007 Range ($ in millions) Low High Net Earnings/(Loss) $(14) $11 Plus Other (Income)/Expense $(2) $(6) Operating Income/(Loss) $(16) $5 Plus Depreciation and Amortization Expense $30 $20 Plus Non-Cash Stock Compensation Expense $1 $0 Adjusted OIBDA $15 $25 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.
