      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 reasons why a
      reasonable estimate of the results cannot be made.

      For the three month period ended June 30, 2008, the registrant had
      revenues of $6,755 and a net loss of $1,036,610. For the three month
      period ended June 30, 2009, the registrant currently estimates that it had
      revenues and a net income of approximately $52,000 and $154,000,
      respectively. Results for the three month period ended June 30, 2009
      remain subject to further adjustment and actual results may differ from
      the foregoing estimates.
