PART III - NARRATIVE


(3)       EXPLANATION OF THE  ANTICIPATED  CHANGE IN RESULTS OF OPERATIONS  FROM
          THE CORRESPONDEING PERIOD FOR THE LAST FISCAL YEAR.

          Pursuant to an Agreement and Plan of Reorganization by and between the
          registrant,  Regent Energy Corporation  ("Regent"),  Vulcan Minerals &
          Energy, Inc., a privately held Texas corporation  ("Vulcan"),  and the
          owners of record of all of the issued and outstanding stock of Vulcan,
          as of March 9, 2001,  the  parties  consummated  an exchange of shares
          (the "Transaction"), which resulted in Vulcan becoming a subsidiary of
          Regent. Also as a result of the Transaction,  Regent is deemed to have
          acquired  all of the  assets,  comprised  primarily  of  oil  and  gas
          properties, of Vulcan.

          As a result of the  Transaction,  the financial  statements of Regent,
          including  the results  for 1999 and 2000,  now reflect the assets and
          operations  of  Vulcan.  There has been some  delay in  preparing  the
          combined  financial  statements  due to a  re-evaluation  of  Vulcan's
          accounting methods and financial results for 1999. In 1999, Vulcan had
          recognized  a gain on the  sale of  certain  interests  in oil and gas
          properties in New Mexico.  Regent and Vulcan have since concluded that
          the gain should not have been recognized.  In addition, a decision has
          been made to change from the successful  efforts method for accounting
          for oil and gas producing activities  previously used by Vulcan to the
          full cost method.  As a result,  net income of Vulcan for 1999 changed
          from  $1,947,676 of income to  $1,857,111  of loss.  The effect of the
          foregoing  on the 2000 and the first  quarter  2001  results  is still
          being analyzed by Regent's auditors.

          In  addition,  Regent  has  had a June 30 year  end and  Vulcan  has a
          December 31 year end.  Regent has had to  determine  which year end to
          elect and to prepare financial statements  accordingly,  which delayed
          the process.
