(Attach Extra Sheets if Needed) The Company has completed a transfer of the Corporate headquarters including all data base records, replaced accounting software programs, established entirely new accounting staff, and hired a new auditing firm all in the last quarter of 2001. These extensive changes have slowed completion of annual reporting and delayed the start of the Company's annual audit. Until the 10-K for 2001 was complete, we could not finalize our first quarter 2002 financials. The 10-K is now complete and we expect to file it this week. The 10-Q will be filed as soon as possible thereafter.
