PART III—NARRATIVE

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

The Registrant has been working diligently to complete its Quarterly Report on Form 10-Q for the quarter ended September 30, 2007 (the “Form 10-Q”). However, the Registrant and the Registrant’s independent registered public accountants have not completed their final review of the Form 10-Q, particularly with respect to the treatment of our September 10, 2007, issuance of preferred stock. We expect the accounting for this issuance in the Form 10-Q, when filed, will differ from that reflected in our earnings release filed on Form 8-K on November 1, 2007. As a result, the Registrant is unable to complete and file its Form 10-Q by the prescribed filing date without unreasonable effort and expense. The Registrant continues to dedicate significant resources to the review of the financial statements and the Form 10-Q, and currently anticipates filing the Form 10-Q on or before November 16, 2007.

If answer is no, identify report(s). Yes x    No ¨

 

  (3) Is it anticipated that any significant change in results of operations from the corresponding period for the last fiscal year will be reflected by the earnings statements to be included in the subject report or portion thereof? Yes ¨    No x

If so, attach an explanation of the anticipated change, both narratively and quantitatively, and, if appropriate, state the reasons why a reasonable estimate of the results cannot be made.
