No offer of securities shall be made except by means of a prospectus meeting the requirements of Section 10 of the Securities Act of 1933, as amended. Use of Non-GAAP Financial Measures. Adjusted EBITDA is calculated as income (loss) from continuing operations before interest expense, foreign exchange gains (losses), financing and related expenses, debt discount and debt settlement expense, gain or loss on extinguishment of debt, acquisition and integration costs, income taxes, asset impairment charges, depreciation and amortization, stock-based compensation expense, change in fair valueof derivatives, and accruals for discretionary bonuses. Since Adjusted EBITDA is a non-GAAP measure that does not have a standardized meaning, it may not be comparable to similar measures presented by other companies. Readers are cautioned that Adjusted EBITDA should not be construed as an alternative to net income (loss) determinedin accordance with U.S. GAAP as an indicator of performance, which is the most comparable measure under GAAP. Adjusted EBITDA is used by management as an internal measure of profitability. We have included Adjusted EBITDA because we believe that this measure is used by certain investors to assess our financial performance before non-cash charges and certain costs that we do not believe are reflective of our underlying business. A reconciliation of Adjusted EBITDA to U.S. GAAP net income is included in our earnings release; however such reconciliation to future net income is not currently available without unreasonable effort. The information that is unavailable is primarily asset impairment and expenses related to stock-based compensation; it is probable that when such amounts are available they will result in a significant GAAP net loss for our second fiscal quarter notwithstanding our expected Adjusted EBITDA results.
