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)

      |X|   (a)   The reason 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 Forms 10-K, 20-F, 11-K, Form N-SAR or Form N-CSR, or
                  portion thereof will be filed on 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
                  12b-25(c) has been attached if applicable.



PART III--NARRATIVE

State below in reasonable detail the reason why Forms 10-K, 20-F, 11-K, 10-Q,
Form N-SAR or Form N-CSR, or the transition report portion thereof, could not be
filed within the prescribed time period. (Attach extra sheets if needed.)

      The registrant is unable to file its Quarterly Report on Form 10-Q for the
      quarter ended March 31, 2009 (the "Report") by the prescribed date of May
      15, 2009, without unreasonable effort or expense because the registrant
      needs additional time to complete certain disclosures and analyses to be
      included in the Report. The registrant intends to file its Report on or
      prior to the fifth calendar day following the prescribed due date.


PART IV--OTHER INFORMATION

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

      Paul C. Levites, Esq.            (212)       400-6900
      --------------------------------------------------------------------------
      (Name)                           (Area Code) (Telephone Number)

(2)   Have all other periodic reports required under Section 13 or 15(d) or 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?

                                                                  |X| Yes |_| No

If so, attach an explanation of the anticipated change, both narratively and
quantitatively, and, if appropriate, state the reason why a reasonable estimate
of the results cannot be made.

During the year ended December 31, 2007, the Registrant was essentially a shell
company and inactive. As reported in the Registrant's interim results during
2008, the Registrant has begun activities and has therefore incurred expenses
and losses related to those start up activities. Preliminary, unaudited
estimates of certain key indicators show material differences from the period
ended March 31, 2008 to the period ended March 31, 2009 (the 2009 amounts shown
below are approximate and are subject to change).

During the quarter ended March 31, 2009, the Registrant incurred net losses of
approximately $(750,307) as compared to net losses of $(1,120,777) during the
quarter ended March 31, 2008. This difference was primarily due to significant
increases in the first quarter of 2009 in expenses in connection with the
Registrant's new business operations in South America offset against a
restatement of expenses of $990,000 in the first quarter of 2008 to take into
account a revaluation of a grant of stock in exchange for services.
