Address of principal executive office     89229 WEST SUNSET BOULEVARD, SUITE 830

                             RULE 12b-25 (b) AND (c)

     If the subject report could not be filed without unreasonable effort or

following should be completed. (Check box if appropriate.)

       | (a) The reasons described in reasonable detail in Part III of this

       |     expense;
       | (b) The subject annual report, semi-annual report, transition report

                                    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 compilation, dissemination and review of the information required to be
presented in the Form 10-QSB for the relevant fiscal quarter has imposed time
constraints that have rendered timely filing of the Form 10-QSB impracticable
without undue hardship and expense to the registrant. The registrant undertakes
the responsibility to file such quarterly report no later than five days after
its original 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 the answer is no,
identify report(s).

                                 |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

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.
