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

The Registrant is unable to file, without unreasonable effort and expense, its Annual Report on Form 10-KSB for the year ended June 30, 2007 because the Registrant’s auditors have not yet completed their audit of the Registrant’s financial statements for the fiscal year ended June 30, 2007.

The Registrant’s auditors are finalizing the audit of its financial statements for the fiscal year ended June 30, 2007, and the Registrant anticipates that the Form 10-KSB, along with the audited financial statements, will be filed on or before the fifteenth calendar day following the prescribed due date of the Registrant’s Form 10-KSB.

If the answer is no, identify report(s).S Yes £ No
