                        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 N-SAR, or portion thereof, will be filed on
|X|         or before the fifteenth  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

      (c)   The  accountant's  statement  or  other  exhibit  required  by  Rule

                              PART III -- NARRATIVE

      State below in reasonable  detail the reasons why Forms 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 Company could not file its annual report by the  prescribed  due
            date because the Company's  independent auditor did not complete its
            audit of the Company's  financial  statements to be included in such
            report.  The  independent  auditor was unable to complete  its audit
            because the Company has devoted its limited financial  resources and
            management  time to explore a financial  transaction  to improve the
            Company's  financial  condition in addition to the work necessary to
            complete the audit. The Company is pursuing transactions,  which, if
            completed,  would  constitute a material  subsequent event and would
            impact the Company's liquidity and capital resources.

            Although the Company is exploring a financial transaction to improve
            its financial  condition,  there are no commitments or  arrangements
            for financings or other  transactions  in place at this time and the
            Company can give no assurance  that capital will be available at all
            or that any transaction  will result.  The Company has been notified
            by its  independent  auditor  that if the  Company  were to file its
            annual report without obtaining a significant capital infusion,  the
            auditor's  report  on the  Company's  financial  statements  for the
            Company's  fiscal  year ended  September  30,  2008  included in the
            annual  report may contain an  explanatory  paragraph  regarding the
            Company's ability to continue as a going concern.

                          PART IV -- OTHER INFORMATION

(1)  Name  and  telephone  number  of  person  to  contact  in  regard  to  this
notification

            Tesfaye Hailemichael             (858) 503-7810
            --------------------------------------------------------------------
            (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).

                                 |X| Yes |_| No


(3) Is it anticipated  that any significant  change in results of operations 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?

                                 |X| Yes |_| 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.

            Although the Company has not  completed  the audit of its  operating
            results,  it expects  that its total sales for its fiscal year ended
            September 30, 2008 will decrease by approximately  $340,000 from its
            total sales of  $5,569,942  for its fiscal year ended  September 30,
            2007, with a corresponding increase in its total operating loss from
            its operating  loss of $387,436 for its fiscal year ended  September
            30, 2007.
