   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, Steven A. Finklea, certify that:

1.    I have reviewed the accompanying annual report on Form 10-K for the year
      ended December 31, 2005 of Treasure Island Royalty Trust, for which
      Wachovia Bank, National Association, acts as trustee;

2.    based on my knowledge, the annual 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 annual report;

3.    based on my knowledge, the financial statements, and other financial
      information included in the annual 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 annual report;

4.    I am responsible for establishing and maintaining disclosure controls and
      procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e), or
      for causing such controls and 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 under my supervision, 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 annual report is being prepared;

      b)    evaluated the effectiveness of the registrant's disclosure controls
            and procedures and presented in the annual report my conclusions
            about the effectiveness of the disclosure controls and procedures,
            as of the end of the period covered by the annual report based on
            such evaluation; and

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

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

      a)    all significant deficiencies and material weaknesses in the design
            or operation of internal control over financial reporting that are
            reasonably likely to adversely affect the registrant's ability to
            record, process, summarize and report financial information; and

      b)    any fraud, whether or not material, that involves persons who have a
            significant role in the registrant's internal control over financial
            reporting.

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