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

be completed. (Check box if appropriate)

       (a)  The reason described in reasonable detail in Part III of this form
            could not be eliminated without unreasonable effort or expense
       (b)  The subject annual report, semi-annual report, transition report on
            Form 10-KSB, Form 20-F, Form 11-K, Form N-SAR or Form N-CSR, or
            portion thereof, will be filed on or before the

PART III -- NARRATIVE

State below in reasonable detail the reasons why Forms 10-KSB, 20-F, 11-K,
10-QSB, N-SAR, N-CSR, or the transition report or portion thereof, could not be
filed within the prescribed time period.

     The Registrant has encountered delays in filing the Quarterly Report on
Form 10-QSB for the quarter ended March 31, 2006, as a result of the delays
encountered with completing the Annual Report on Form 10-KSB, filed on May 15,
2006. Residual administrative issues have unexpectedly extended this process.
This delay could not be eliminated by the registrant without undue effort or
expense.
