  CERTIFICATION OF VICE PRESIDENT OF TRUSTEE OF TREASURE ISLAND ROYALTY TRUST
             PURSUANT TO 15 U.S.C. SECTION 7241, AS ADOPTED PURSUANT
                TO SECTION 302 OF THE SARBANES-OXLEY ACT OF 2002


I, Kevin M. Dobrava, certify that:

1.    I have reviewed the accompanying quarterly report on Form 10-Q for the
      quarterly period ended September 30, 2003 of Treasure Island Royalty
      Trust, for which Wachovia Bank, National Association, acts as trustee;

2.    Based on my knowledge, the quarterly 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
      the quarterly report;

3.    Based on my knowledge, the financial statements, and other financial
      information included in the quarterly report, fairly present in all
      material respects the financial condition, distributable income and
      changes in trust corpus of the registrant as of, and for, the periods
      presented in the quarterly report;

4.    I am responsible for establishing and maintaining disclosure controls and
      procedures (as defined in Exchange Act Rules 13a-14 and 15d-14), or for
      causing such procedures to be established and maintained, for the
      registrant and I have:

      a)    designed such disclosure controls and procedures, or caused such
            controls and procedures to be designed, to ensure that material
            information relating to the registrant, including its consolidated
            subsidiaries, is made known to me by others within those entities,
            particularly during the period in which the quarterly report is
            being prepared; and

      b)    evaluated the effectiveness of the registrant's disclosure controls
            and procedures as of the end of the period covered by this report;

5.    I have disclosed, based on my most recent evaluation, to the registrant's
      auditors:

      a)    all significant deficiencies in the design or operation of internal
            controls which could adversely affect the registrant's ability to
            record, process, summarize and report financial data and have
            identified for the registrant's auditors any material weaknesses in
            internal controls; and

      b)    any fraud, whether or not material, that involves persons who have a
            significant role in the registrant's internal controls; and

6.    I have indicated in this quarterly report whether or not there were
      significant changes in internal controls or in other factors that could
      significantly affect internal controls subsequent to the date of my most
      recent evaluation, including any corrective actions with regard to
      significant deficiencies and material weaknesses.

In giving the certifications in paragraphs 4, 5 and 6 above, I have relied to
the extent I consider reasonable on information provided to me by Newfield
Exploration Company.
