ITEM 2.  Acquisition or Disposition of Assets

         On March 31, 2004, the Company acquired interests in 138 western
Pennsylvania gas wells from Delta Petroleum Corporation (Nasdaq: DPTR)
("Delta"). The Company previously owned most of these properties through May 31,
2002 when it sold all of its United States oil and gas properties to Delta. The
purchase price paid by the Company was $8,121,000 consisting of $8,000,000 for
the agreed-upon purchase price as of January 1, 2004 plus $121,000 of net
expenses paid by Delta from January 1, 2004 to March 31, 2004. The effective
date of the purchase was January 1, 2004. The Company estimates that it will
receive approximately $450,000 of purchase price adjustments at a final
accounting before June 30, 2004, resulting in a net purchase price of
approximately $7,671,000. Such purchase price adjustments represent estimated
cash flow from the properties from January 1, 2004 to March 31, 2004 excluding
the $121,000 of net expenses during that period already paid by Delta. On March
9, 2004 and March 25, 2004, the Company sold an aggregate 2,260,414 shares of
Delta Common Stock for aggregate net proceeds of $20,917,797. Following these
sales, the Company now owns approximately 25% of Delta

         In addition, Joseph Castle, the Company's Chairman, President and Chief
Executive Officer, and John Keller and Russell Lewis, both of whom are directors
of the Company, are also directors of Delta.
