Additional time will be needed for the registrant to complete the preparation and review of the registrant’s Quarterly Report on Form 10-Q for the quarter ended June 30, 2005 (the “Form 10-Q”). The registrant has dedicated considerable time and effort to the preparation of the Form 10-Q. Notwithstanding management’s efforts and a substantial expenditure of resources, the preparation and review of the Form 10-Q is not completed. As a result, the registrant requires additional time to complete the preparation and review of the Form 10-Q.

The Form 10-Q will be filed as soon as reasonably practicable.
