(Check box if appropriate.) [X] (a) The reasons described in reasonable detail in Part III of this form could not be eliminated without unreasonable effort or expense [X] (b) The subject annual report, semi-annual report, transition report on Form 10-K or Form 10-KSB, Form 20-F, 11-K or Form N-SAR, or portion thereof will be filed on or before the fifteenth calendar day following the prescribed due date; or the subject quarterly report or transition report on Form 10-Q [or Form 10-QSB], or portion thereof will be filed on or before the fifth calendar day following the prescribed due date; and [ ] (c) The accountants statement or other exhibit required by the Rule 12b-25(c ) has been attached if applicable. Part III- Narrative The Company prepared its Form 10-K and related exhibits using the Microsoft Word software package. The Word document was finalized by noon on March 30, 2000, the filing due date. However, when the document was loaded into the EDGAR reporting system, the following problems were encountered with the formatting: o All of the Consolidated Financial Statements and tables presented in the Notes to Consolidated Statements and other sections of the 10-K were unreadable and had to be reconstructed manually within EDGAR. o The margins for every paragraph of every document had to be reset in EDGAR. (The Form 10-K is approximately 220 pages, including exhibits.) o Numerous characters such as apostrophes, quotation marks, and copyright marks were not readable by the EDGAR program and had to be deleted or retyped. (The total number of these errors exceeded EDGAR'S count capability) The administrator who was responsible for loading the document into EDGAR had no previous experience with the reporting system. Despite working on the document for 12 hours on March 30, 2000 trying to meet the reporting deadline, we were not able to resolve all of the reporting format issues until the afternoon of March 31, 2000, whereupon the Form 10-K was filed electronically with the SEC. Upon discussions with our auditors, we have subsequently learned that approximately 85% of their clients send this document to an outside source for formatting prior to loading it into EDGAR.
