                            RULES 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 appropriate box.)  |X| Yes  |_| No

|X| | (a) The reasons described in reasonable detail in Part III of this form
    |     could not be eliminated without unreasonable effort or expense;
    |
|X| | (b) The subject annual report, semi-annual report, transition report on
    |     Form 10-K, 20-F, 11-K or N-SAR, or portion thereof, will be filed on
    |     or before the 15th calendar day following the prescribed due date; or

                                    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 or portion thereof, could not be filed within
the prescribed time period.

Registrant requires additional time to comply with recent Federal securities
laws, particularly regarding the internal controls requirements.  Consequently,
Registrant's accounting department requires additional time to accumulate and
review its subsidiaries' financial information in order to complete the
consolidation process and evaluate internal controls, and cannot, without
unreasonable effort and expense, file its Form 10-QSB on or before the
prescribed filing date. Registrant hopes to obtain all required data within the
next several days and, as a result, intends to file the Form 10-QSB within five
days after the prescribed filing date.

                                    PART IV
                               OTHER INFORMATION

       (Name)                                    (Area Code) (Telephone Number)

(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 answer is no,
identify report(s). || Yes |X| No.  10-KSB for year ended December 31, 2002 has
not yet been filed.

(3)  Is it anticipated that any significant change in results of operation for
     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

     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.
