PART II — RULES 12b-25(b) AND (c)

If the subject report could not be filed without unreasonable effort or expense and the registrant seeks relief pursuant to Rule 12b-25(b), the following should be completed. (Check box if appropriate) þ

(a) The reasons 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-K, Form 20-F, Form 11-K, Form N-SAR or Form N-CSR, or portion thereof, will be filed on or before the fifteenth calendar day following the prescribed due date; or the subject quarterly report or transition report on Form 10-Q or subject distribution report on Form 10-D, or portion thereof, will be filed on or before the fifth calendar day following the prescribed due date; and

PART III — NARRATIVE

     State below in reasonable detail the reasons 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.

     Effective January 28, 2009, the Company’s Chief Financial Officer resigned. The Chief Financial Officer had primary responsibility for preparing the consolidated financial statements, drafting the Annual Report on Form 10-K and interfacing with the independent auditor. The Company is actively seeking to fill this position, but to date has not. The loss of the Chief Financial Officer has caused a diversion of management’s time and attention, which, combined with the limited resources of the finance department, has caused the unforeseen delay in completing the Annual Report on Form 10-K on a timely basis. The Registrant expects to file its Annual Report on Form 10-K for the year ended December 31, 2008 on or before March 31, 2009.
