   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 quarterly report on Form 10-Q for the
     quarterly period ended March 31, 2007 of Treasure Island Royalty Trust, for
     which U.S. Bank National Association, acts as trustee;

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 and results of operations of the registrant as of,
     and for, the periods presented in this 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 procedures to be established and maintained, for the
     registrant and I have:

     a)   designed such disclosure controls and procedures, or caused such
          disclosure 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 this report is being prepared;

     b)   evaluated the effectiveness of the registrant's disclosure controls
          and procedures and presented in this report my 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

     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 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 of internal control
     over financial reporting, 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.
