                          TREASURE ISLAND ROYALTY TRUST

                          NOTES TO FINANCIAL STATEMENTS
                                   (UNAUDITED)

1.   FORMATION AND PURPOSE OF THE TRUST

     Treasure Island Royalty Trust was established in connection with Newfield
Exploration Company's November 2002 acquisition of EEX Corporation to provide
the shareholders of EEX with the option to receive an interest in an exploration
concept being pursued by EEX prior to the acquisition. The concept, referred to
as "Treasure Island," targets "ultra deep" prospects in the shallow waters of
the Gulf of Mexico. The trust owns, or has the right to receive, overriding
royalty interests to be paid from Newfield's (or its transferees') interest in
any future production that may be achieved from horizons below specified depths
in the Treasure Island area. Treasure Island remains an exploration concept and
there are no proved reserves or production currently associated with the royalty
interests.

     The trust was created under the laws of the State of Texas. The beneficial
interest in the trust is divided into 42,574,298 trust units, each of which
represents an equal undivided portion of the trust. At the time of Newfield's
acquisition of EEX, Newfield and Wachovia Bank, National Association entered
into an amended and restated trust agreement with respect to the trust and the
trust issued all 42,574,298 trust units to Newfield. Newfield subsequently
transferred all of the trust units to the holders of EEX stock who elected to
receive trust units as a portion of their consideration in the acquisition. U.S.
Bank National Association succeeded Wachovia as trustee in September 2006 upon
Wachovia's sale of its corporate trust business to U.S. Bank.

     The sole purpose of the trust is to hold non-expense bearing overriding
royalty interests in any future production from a specified area. The royalty
interests are passive in nature. The trustee of the trust and the trust's
unitholders have no control over, or responsibility for any costs related to,
drilling, development or operations. Neither Newfield nor any other operator of
Treasure Island properties has any contractual commitment to the trust to
conduct drilling on the properties or to maintain its ownership interest in any
of the properties.

     These unaudited financial statements reflect, in the opinion of the
trustee, all adjustments, consisting only of normal and recurring adjustments,
necessary to fairly state the trust's financial position as of, and results of
operations for, the periods presented. These financial statements have been
prepared in accordance with the instructions to Form 10-Q and, therefore, do not
include all disclosures required for financial statements prepared in conformity
with generally accepted accounting principles.

     For financial accounting purposes, the value of the overriding royalty
interests are assessed quarterly for possible impairment. An impairment
requiring a charge to earnings may result from the evaluation of drilling
results or the expiration or relinquishment of leaseholds associated with
prospects. As a result of the relinquishment of a leasehold, the trust recorded
an impairment charge of $47,000 in the first quarter of 2007.

     Interim period results are not necessarily indicative of results for a full
year.

     These financial statements and notes should be read in conjunction with the
trust's audited financial statements and the notes thereto for the year ended
December 31, 2006 included in the trust's annual report on Form 10-K.

2.   FEDERAL INCOME TAX

     Under current law, the trust is taxable as a grantor trust and not as a
business entity, although there is a remote possibility that the Internal
Revenue Service would attempt to treat the trust as a business entity. A grantor
trust is not subject to tax at the trust level. For tax purposes, trust
unitholders are considered to own the trust's income and principal as though no
trust were in existence.

ITEM 2. TRUSTEE'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
     OPERATIONS

OVERVIEW

     CREATION AND PURPOSE OF THE TRUST. Treasure Island Royalty Trust was
established in connection with Newfield Exploration Company's November 2002
acquisition of EEX Corporation to provide the shareholders of EEX with the
option to receive an interest in an exploration concept being pursued by EEX
prior to the acquisition. The concept, referred to as "Treasure Island," targets
"ultra deep" prospects in the shallow waters of the Gulf of Mexico. The trust
owns, or has the right to receive, overriding royalty interests to be paid from
Newfield's (or its transferees') interest in any future production that may be
achieved from horizons below specified depths in the Treasure Island area. The
sole purpose of the trust is to hold these overriding royalty interests. The
royalty interests are passive in nature. The trustee of the trust and the
trust's unitholders have no control over, or responsibility for any costs
related to, drilling, development or operations. Neither Newfield nor any other
operator of Treasure Island properties has any contractual commitment to the
trust to conduct drilling on the properties or to maintain its ownership
interest in any of the properties.

     TREASURE ISLAND. "Treasure Island" refers to a concept developed to explore
for oil and gas in "ultra deep" horizons below a salt weld located at a true
vertical depth of 18,000 to 22,000 feet in the shallow waters of the Gulf of
Mexico. The Treasure Island area covers horizons below specified depths in 116
lease blocks located offshore Louisiana in the South Timbalier, Ship Shoal,
South Marsh Island and Eugene Island areas. The specified depth or depths for
each of the blocks vary and were agreed upon by EEX and Newfield prior to
Newfield's acquisition of EEX. The depths do not correspond exactly to the
location of the base of the salt weld in all cases. Treasure Island remains an
exploration concept and there are no proved reserves or production currently
associated with the royalty interests. Treasure Island exploratory wells require
significant lead time to plan and drill and are very expensive and technically
challenging because of the depth of the targeted horizons and expected harsh
conditions such as high temperature and pressure.

     The trust currently holds an interest in 14 lease blocks within the
Treasure Island area. Four of these leases will expire at the end of May or June
2007 and one is scheduled to expire at the end of April 2009. The remaining nine
leases have been extended beyond their initial terms - five are associated with
the Blackbeard West Prospect, which is discussed further below, and four relate
to other prospects. All of the latter four leases are scheduled to expire in the
third quarter of 2008. Newfield is working on plans to continue to retain these
leases, but its success is uncertain. An overriding royalty interest with
respect to a particular lease block will terminate if the lease expires.

     In August 2006, Newfield announced results from the first well to test the
Treasure Island concept, the "Blackbeard West #1" well. Exxon Mobil Corporation
was the operator of the well and BP Exploration and Production Inc. and
Petrobras America Inc. also participated in the well. The Blackbeard West
Prospect is subject to a 1.25% overriding royalty interest held by the trust.
The well was spud in early February 2005 and drilled to a total depth of 30,067
feet. The well encountered a thin gas bearing sand below 30,000 feet but failed
to reach its primary targets because of higher than expected pressure. After the
well was temporarily abandoned, Newfield became the operator and Exxon Mobil
Corporation withdrew from the prospect.

     In the first quarter of 2007, the Minerals Management Service, or MMS,
granted Newfield an extension for the five Blackbeard West leases through August
2008. Newfield will work to complete a schedule of activities provided to the
MMS that may further extend these leases, but its success is uncertain. During
the extension period, Newfield intends to use the information gathered from the
well to investigate whether an economically feasible well can be designed to
safely test the prospect.

     Newfield anticipates that it will be at least two years before drilling of
a redesigned well or reentry into the existing well bore could commence. Because
of the high drilling costs and risks and Exxon Mobil's withdrawal, it is
unlikely that Newfield will commence drilling activities without one or more new
partners to pay a portion of the costs of further operations. Newfield does not
anticipate that it will commence drilling activities on any other prospect or
acquire interests in any additional Treasure Island lease blocks until the
Blackbeard West Prospect has been successfully tested.

RESULTS OF OPERATIONS

     The trust has had no revenue. The trust incurred $29,142 and $29,869 of
administrative and interest expenses for the first quarter of 2007 and 2006,
respectively. Administrative expense consists primarily of legal, accounting and
trustee fees and printing and mailing costs.

     For financial accounting purposes, the value of the overriding royalty
interests are assessed quarterly for possible impairment. An impairment
requiring a charge to earnings may result from the evaluation of drilling
results or the expiration or relinquishment of leaseholds associated with
prospects. As a result of the relinquishment of a leasehold, the trust recorded
an impairment charge of $47,000 in the first quarter of 2007.

LIQUIDITY AND CAPITAL RESOURCES

     The trust's only sources of income are revenue, if any, attributable to the
overriding royalty interests, income from the investment of cash on hand and net
proceeds from the disposition of royalty interests. Because none of the
properties underlying the royalty interests are at present producing any oil or
gas and the trust has only a very small amount of cash on hand, the trust has no
source of revenue. Therefore, it must rely on Newfield for the funding of its
administrative expenses. Any material adverse change in Newfield's financial
condition or results of operations could materially and adversely affect the
trust and the trust unitholders.

     Until the royalty interests begin generating cash proceeds, Newfield has
agreed to make loans from time to time to fund the routine administration of the
trust. In addition, if after such time as the royalty interests commence
generating cash proceeds, 8% of the cash held by the trust at the end of a
calendar quarter is insufficient to cover the administrative expenses of the
trust, Newfield will lend the difference to the trust. Loans from Newfield bear
interest at an annual rate of 8% and are senior unsecured obligations of the
trust. The loans (including accrued interest) will be repaid in quarterly
installments to the extent that 8% of the cash received by the trust in a given
quarter exceeds the administrative expenses of the trust for that quarter. As of
March 31, 2007, the trust had borrowed $368,441 since inception to pay
administrative expenses and had incurred interest of $62,959, none of which had
been repaid.

FORWARD LOOKING INFORMATION

     This report contains information that is forward-looking or relates to
anticipated future events or results such as drilling and operating plans.
Although Newfield and the trustee believe that the expectations reflected in
this information are reasonable, this information is based upon assumptions and
anticipated results that are subject to numerous uncertainties. Please read the
discussions under the captions "Treasure Island" in Item 1 of Part I and "Risk
Factors" in Item 1A of Part I of the trust's annual report on Form 10-K for the
year ended December 31, 2006.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     None.

ITEM 4. CONTROLS AND PROCEDURES

     As of the end of the period covered by this report, the trustee carried out
an evaluation of the effectiveness of the design and operation of the trust's
disclosure controls and procedures pursuant to Exchange Act Rule 15d-15(b).
Based upon that evaluation, the trustee concluded that the trust's disclosure
controls and procedures are effective in timely alerting the trustee to material
information relating to the trust required to be included in the trust's
periodic filings with the Securities and Exchange Commission. In its evaluation
of disclosure controls and procedures, the trustee has relied, to the extent
considered reasonable, on information provided by Newfield Exploration Company.
There has not been any change in the trust's internal control over financial
reporting during the period covered by this report that has materially affected,
or is reasonably likely to materially affect, the trust's internal control over
financial reporting.
