                                    NARRATIVE

         State below in reasonable detail the reasons why Form 10-K and

or portion thereof could not be filed within the prescribed time period.
(Attach extra sheets if needed.)

         Due to the Company's recent restatement to its financial statements,
the defense of certain class action lawsuits arising out of such restatement,
the default on its senior notes and its efforts to workout the default with its
senior note holders, the resignation of its chief executive officer, the
termination of its chief financial officer, the appointment of a new chairman of
the board, a new chief executive officer and a new acting chief financial
officer, the Company's recent on-going investigation into the possible improper
conversion of corporate funds for the personal use of certain former officers
and the Company's required attention to all of these urgent matters, the Company
has been unable to complete by the required filing date its quarterly report on
Form 10-Q for the quarter ended June 30, 2002 without unreasonable effort and
expense.

                                     PART IV

          the Company's announced divestiture of its Oil and Gas Assets,
          including the August 2002 sale of a majority of the assets of DDD
          Energy, Inc.;

     o    an impairment of the seismic data library in accordance with SFAS
          No. 144 of approximately $26 million;

     o    a change in accounting principle in 2002 with an aggregate six month
          effect of approximately $26 million; and

     o    a valuation allowance relating to its deferred tax assets of
          approximately $22 million.

     In addition, the Company's auditors have advised the Company that their
report with respect to the Company's 2001 financial statements, which will be
included in its Form 10-K/A (Amendment No. 3) that the Company intends to file

debt covenants. Further, the Company's auditors have advised the Company that,
if the non-compliance is not satisfactorily resolved, their report on the
Company's December 31, 2002 financial statements will include a "going concern"
modification.
