                               PART III. NARRATIVE

filed within the prescribed time period.

     The Registrant cannot file the Quarterly Report on Form 10-Q for the period
ended  September 30, 2006 within the prescribed  time period because the Company
does not have all  information  necessary  to complete  the  required  financial
reports by November 14, 2006. The Company will file the Quarterly Report on Form
10-Q for the period ended September 30, 2006 with completed financial statements
as soon as practicable.

          period that the  Registrant  was  required to file such  reports  been
