PART III--NARRATIVE State below in reasonable detail the reasons why the Form 10-K, 11-K, 10-Q, N-SAR, or the transition report or portion thereof, could not be filed within the prescribed time period. (ATTACH EXTRA SHEETS IF NEEDED) Narrative for 12b-25 Filing for the Quarterly Report on Form 10-Q for the Quarterly Period Ended September 30, 1997 ------------------------------------------------- In a recent 1997 announcement, the staff of the Securities and Exchange Commission (the "SEC") indicated that when preferred stock is convertible at a discount from the then current common stock market price, such discounted amount reflects an incremental yield, which then should be recognized as a current return to the preferred shareholders. The Registrant completed an offering of this type of preferred stock in fiscal 1996 and did not, at that time, so account for such offering. Therefore, the Registrant and its outside auditors have been considering the extent to which its earlier and current reports have been affected and need to be amended in response to the SEC announcement. Due to the Registrant's extremely limited financial and personnel resources (which included only one full-time employee with financial reporting duties), the report therefore could not be completed and filed within the prescribed time period.

If the answer is no, identify report(s). [X] Yes [_] No --------------------------------------------------------------------------- (3) Is it anticipated that any significant change in results of operations from the corresponding period for the last fiscal year will be reflected by the earnings statements to be included in the subject report or portion thereof? [_] Yes [X] No If so, attach an explanation of the anticipated change, both narratively and quantitatively, and, if appropriate, state the reasons why a reasonable estimate of the results cannot be made.
