                                     PART II
                             RULE 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.)

          (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, 20-F, 11-K or Form 10-Q, or portion thereof
[X]            will  be  filed  on or before the 15th calendar day following the
               prescribed  due  date;  or  the  subject  quarterly  report  or
               transition  report on Form 10-Q, 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 Form 10-K, 11-K, 20-F,
10-Q,  N-SAR  or the transition report portion thereof could not be filed within
the  prescribed  time  period.

The  Registrant's  annual report on Form 10-KSB could not be timely filed due to
the  executive  officers  of  the  Company and the Company's auditors not having
sufficient  time  and  information  to  complete  their review process. We fully
expect  to  file  the  final  Form  10-KSB  before  the  time  permitted by this
extension.
                                     PART IV

(2)  Have  all  other periodic reports required under Section 13 or 15(d) of the
Securities  Exchange  Act of 1934 or Section 30 of the Investment Company Act of
1940  during  the  preceding  12  months  or  for  such  shorter period that the
registrant was required to file such report(s) been filed?  If the answer is no,

                                    [x] Yes  [ ] 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  [x] No
