Since EBITDA (generally, net income plus interest expenses, taxes, depreciation and amortization) is not calculated identically by all companies, this presentation may not be comparable to EBITDA or Adjusted EBITDA presentations disclosed by other companies. Adjusted EBITDA represents net income with adjustments for net financing costs, depreciation and amortization, provision for income taxes, stock compensation expense, goodwill and other intangible assets impairments, loss on disposition of business, transaction expenses and acquisition, reorganization and nonrecurring costs. Management believes that Adjusted EBITDA is useful in evaluating the Company’s operating performance compared to that of other companies in its industry because the calculation of Adjusted EBITDA generally eliminates the effects of certain non-cash and other items that may vary for different companies for reasons unrelated to overall operating performance. In addition, the Company’s management used Adjusted Net Income as a measure of earnings to eliminate the effects of certain non-cash and nonrecurring items of the Company. Adjusted Net Income represents net income with tax-effected adjustments for stock compensation expense, goodwill and other intangible assets impairments, loss on disposition of business, transaction expenses and acquisition, reorganization and nonrecurring costs. However, Adjusted EBITDA and Adjusted Net Income are not recognized measurements under GAAP and should not be considered as an alternative to the most

directly comparable measures presented in accordance with GAAP. A reconciliation of these non-GAAP measures to the most directly comparable GAAP measures is included above. Use of Non-GAAP Financial Measures
