10-Q, N-SAR, or the transition report portion thereof, could not be filed within
the prescribed time period. (Attach extra sheets if needed)

Due to delay in commencement and completion of auditor review resulting from
auditor-requested financial assurances from the Company based on the Company's
limited resources, additional time is needed for the completion of the Company's
Form 10-QSB for the quarter ended 9/30/04. The company intends to file the above
referenced Form 10-QSB as soon as possible, but not later than 11/19/2004.
