Forward-Looking Statements In this press release, our use of the words "outlook," "expect," "anticipate," "estimate," "forecast," "project," "likely," "objective," "plan," "designed," "goal," "target," and similar expressions is intended to identify forward-looking statements. While these statements represent our current judgment on what the future may hold, and we believe these judgments are reasonable, actual results may differ materially due to numerous important risk factors that are described in our Annual Report on Form 10-K for the period ended December 31, 2004, as filed with the SEC on March 30, 2005, which may be revised or supplemented in subsequent reports filed by us with the SEC. Such risk factors include, but are not limited to: our level of indebtedness; an inability to generate sufficient cash to service our indebtedness; regulatory and legal uncertainty with respect to intercarrier compensation payments received by us; the inability to expand our business as a result of the unavailability of funds to do so; the migration to broadband Internet access affecting dial-up Internet access; the loss of key executive officers could negatively impact our business prospects; an increase in our network expenses which could result if the migration of our enterprise customer base to U.S. TelePacific Corp. occurs sooner or later than contemplated; and our principal competitors for local services and potential additional competitors have advantages that may adversely affect our ability to compete with them.
