(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 reports)

         If the answer is no, identify report(s).

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

         report or portion thereof?       [X] Yes [ ] No

         If so, attach an explanation of the anticipated change, both

         On December 31, 2001, the registrant acquired the assets and capital
         stock of Couba Operating Company which was primarily engaged in the
         production of oil from properties located in St. Charles Parish,
         Louisiana. As a consequence of this acquisition, the Registrant's
         assets, liabilities, revenues and scale of operations in 2003 has
         increased over its operations in 2002 and 2001. The change in the
         registrant's scale of operations will continue to impact its operating
         results for the nine months ended September 30, 2003.
