16. Safe harbor Certain statements contained in this presentation constitute forward-looking statements. These statements may include, without limitation, statements concerning future results of operations, the impact of regulatory initiatives on KPN’s operations, its and its joint ventures' share of new and existing markets, general industry and macro-economic trends and KPN’s performance relative thereto, and statements preceded by, followed by or including the words “believes”, “expects”, “anticipates” or similar expressions. These forward-looking statements rely on a number of assumptions concerning future events and are subject to uncertainties and other factors, many of which are outside our control that could cause actual results to differ materially from such statements. A number of these factors are described (not exhaustively) in the KPN’s 2007 Annual Report. All figures in this presentation are unaudited and based on IFRS. This presentation contains a number of non-GAAP figures, such as EBITDA and free cash flow. These non-GAAP figures should not be viewed as a substitute for KPN’s GAAP figures. All market share information in this presentation is based on management estimates based on externally available information, unless indicated otherwise. Regarding iBasis, various remarks that we may make about future expectations, plans, and prospects for iBasis constitute forward-looking statements for purposes of the safe harbor provisions under The Private Securities Litigation Reform Act of 1995.  Forward-looking statements include but are not limited to statements regarding the amount and timing of achievement of transaction synergies, anticipated costs and our expectations regarding resumption of growth. Actual results may differ materially from those indicated by these forward-looking statements as a result of various important factors, including those discussed in the Company’s Form 10-K for the year ended December 31, 2007, and other current and periodic reports on file with the SEC. Disclaimer We define EBITDA as operating result before depreciation and impairments of PP&E and amortization and impairments of intangible assets. Note that our definition of EBITDA deviates from the literal definition of earnings before interest, taxes, depreciation and amortization and should not be considered in isolation or as a substitute for analyses of the results as reported under IFRS. In all cases, a reconciliation of EBITDA and the nearest GAAP measure (operating result) is provided. In the net debt/EBITDA ratio, we define EBITDA as a 12 month rolling average excluding book gains and restructuring costs, both over EUR 20m. For 2007, we define free cash flow as cash flow from operating activities plus proceeds from real estate, minus capital expenditures (Capex), being expenditures on PP&E and software. For 2008 and subsequent years, free cash flow is defined as cash flow from operating activities plus proceeds from real estate, minus capital expenditures (Capex), being expenditures on PP&E and software, and excluding tax recapture at E-Plus. The unaudited pro-forma financial information for KPN Mobile The Netherlands and the Fixed division (including Other) for 2007 has been prepared based on the former organizational structure in place as at December 31, 2006 and on the transfer pricing, roaming and intercompany charges associated with that former structure. Although we believe that the pro-forma financial information has been prepared based on reasonable assumptions, this information is provided for illustrative purposes only and we cannot assure you that the pro-forma financial information based on the former organizational structure would be identical to the actual results which might have been reported had our organization structure not changed.
