~~Cautionary Statement Regarding Financial and Operating Data~~ 2

~~As a~~ ~~result of actions taken by management during the time it was controlled by the Rigas~~ ~~family:~~ ~~(a) the Company has not yet completed its financial statements as of or for the~~ years ended December 31, 2002 and 2001, or received its independent public accountants’ report thereon or filed with the Securities and Exchange Commission 2001; (b) the Company’s former independent public accountants, Deloitte & Touche LLP, suspended their auditing work on the Company’s financial statements as of and for the year ended December 31, 2001 and withdrew their audit report with respect to the year ended December 31, 2000; (c) the Company has not yet completed its financial statements or filed with the Commission its Quarterly Report on Form 10-Q as of and for the quarterly periods ended June 30, 2003 or March 31, 2003; (d) the Company has not yet completed its financial statements or filed with the Commission its Quarterly Report on Form 10-Q as of and for the quarterly periods ended September 30, 2002, June 30, 2002 or March 31, 2002; and (e) the Company expects to restate its financial statements for the years ended December 31, 2000 and 1999, and its interim financial statements for 2001 and possibly other periods. New management took control of the Company in May 2002 and retained new independent auditors and began the preparation of new financial statements for the periods in question. As a result of certain actions of Rigas management that the Company has previously disclosed, the Company is unable to predict at this time when such financial statements will be completed. In addition, current management believes that the public information provided by Rigas management on other matters of interest to investors, such as the Company’s rebuild percentage (the percentage of the Company’s cable television systems that the Company believes have been upgraded to current standards), was unreliable. As a result, the Company anticipates that it may have to supplement the financial and other information contained in this Form 8-K and that such supplemental information may be material. SIGNATURE

2 Pursuant to the requirements of the Securities Exchange Act of 1934, as amended, each registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.
