                         THE SARBANES-OXLEY ACT OF 2002

      I, Hugh Idstein, certify that:

      1. I have reviewed this annual report on Form 10-KSB of Dune Energy, Inc.;

      2. Based on my knowledge, this report does not contain any untrue
statement of a material fact or omit to state a material fact necessary to make
the statements made, in light of the circumstances under which such statements
were made, not misleading with respect to the period covered by this report;

      3. Based on my knowledge, the financial statements, and other financial
information included in this report, fairly present in all material respects the
financial condition, results of operations and cash flows of the small business
issuer as of, and for, the periods presented in this report;

      4. The small business issuer's other certifying officer(s) and I are
responsible for establishing and maintaining disclosure controls and procedures
(as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) and internal control
over financial reporting (as defined in Exchange Act Rules 13a-15(f) and
15d-15(f)) for the small business issuer and have:

            (a) Designed such disclosure controls and procedures, or caused such
      disclosure controls and procedures to be designed under our supervision,
      to ensure that material information relating to the small business issuer,
      including its consolidated subsidiaries, is made known to us by others
      within those entities, particularly during the period in which this report
      is being prepared.

            (b) Designed such internal control over financial reporting, or
      caused such internal control over financial reporting to be designed under
      our supervision, to provide reasonable assurance regarding the reliability
      of financial reporting and the preparation of financial statements for
      external purposes in accordance with generally accepted accounting
      principles;

            (c) Evaluated the effectiveness of the small business issuer's
      disclosure controls and procedures and presented in this report our
      conclusions about the effectiveness of the disclosure controls and
      procedures, as of the end of the period covered by this report based on
      such evaluation; and

            (d) Disclosed in this report any change in the small business
      issuer's internal control over financial reporting that occurred during
      the small business issuer's most recent fiscal quarter (the small business
      issuer's fourth fiscal quarter in the case of an annual report) that has
      materially affected, or is reasonably likely to materially affect, the
      small business issuer's internal control over financial reporting; and


                                       42

      5. The small business issuer's other certifying officer(s) and I have
disclosed, based on our most recent evaluation of internal control over
financial reporting, to the small business issuer's auditors and the audit
committee of the small business issuer's board of directors (or persons
performing the equivalent functions);

            (a) All significant deficiencies and material weaknesses in the
      design or operation of internal control over financial reporting which are
      reasonably likely to adversely affect the small business issuer's ability
      to record, process, summarize and report financial information; and

            (b) Any fraud, whether or not material, that involves management or
      other employees who have a significant role in the small business issuer's
      internal control over financial reporting.
