                                    NARRATIVE



The Registrant is unable to timely file its Form 10-K for the period ended
December 31, 2004, because the audit of the financial statements of the
Registrant is not complete. Our Auditors, Pannell Kerr Forster of Texas, P.C.,
were engaged on February 24, 2005 and the time required to complete the audit
was not sufficient and could not be completed without unreasonable effort and
expense on behalf of the Company. The Registrant expects to file its Form 10-K
within the 15 calendar days provided by this extension.


                                     PART IV
