USE OF PROJECTIONS

This Presentation contains projected financial information with respect to the Company. Such projected financial information constitutes forward-looking information and is for illustrative purposes only and should not be relied upon as necessarily being indicative of future results. The assumptions and estimates underlying such financial information are inherently uncertain and are subject to a wide variety of significant business, economic, competitive, and other risks and uncertainties. See "Forward-Looking Statements" above. Actual results may differ materially from the results contemplated by the financial forecast information contained in this Presentation, and the inclusion of such information in this Presentation should not be regarded as a representation by any person that the results reflected in such forecasts will be

achieved.

FINANCIAL INFORMATION; NON-GAAP FINANCIAL MEASURES

Some of the financial information and data contained in this Presentation, such as Adjusted EBITDA, and Adjusted Gross Profit has not been prepared in accordance with United States generally accepted accounting principles ("GAAP"). The Company believes these non-GAAP measures of financial results provide useful information to management and investors regarding certain financial and business trends relating to the Company's financial condition and results of operations. The Company's management uses these non-GAAP measures for trend analyses and for budgeting and planning purposes. A reconciliation of these non-GAAP financial measures to the closest GAAP measure is included in the Appendix to the Presentation. You should review the Company's audited financial statements prepared in accordance with

GAAP, which are included in its Annual Report on Form 10-K filed with the SEC. Forward-lookingnon-GAAP financial measures are presented without reconciliations to GAAP measures because the GAAP financial measures are not accessible on a forward-looking basis, and reconciling information is not available without unreasonable effort due to the inherent difficulty in forecasting and quantifying certain amounts that are necessary for such reconciliations. For the same reasons, the Company is unable to address the probable significance of the unavailable information, which could be material to future results.
