If the subject report could not be filed without unreasonable effort or expense

be completed. (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, Form 20-F, Form 11-K or Form N-SAR, or portion thereof will
be filed on or before the fifteenth calendar day following the prescribed due

                                    NARRATIVE

         State below in reasonable detail the reasons why Forms 10-K, 20-F,
11-K, 10-Q, N-SAR or the transition report portion thereof could not be filed
within the prescribed time period. (Attach Extra Sheets if Needed)

                     The Registrant is unable to timely file its report on Form
           10-QSB for the fiscal quarter ending March 31, 2001, without
           unreasonable effort or expense, because of an inability to timely
           obtain adequate information regarding disclosure on outstanding debt
           agreements. The Registrant anticipates completing the filing of its
           quarterly report on Form 10-QSB no later than the 5th calendar day
           following the prescribed due date.
