PART I - FINANCIAL INFORMATION

Item 1. Financial Statements.

The condensed financial statements included herein are presented, without audit, pursuant to the rules and regulations of the Securities and Exchange
Commission. Certain information and footnote disclosures normally included in annual financial statements have been condensed or omitted pursuant to such rules and regulations, although the trustee believes that the disclosures are adequate to make
the information presented not misleading. These condensed financial statements should be read in conjunction with the financial statements and the notes thereto included in the trusts latest Annual Report on Form
10-K. In the opinion of the trustee, all adjustments, consisting only of normal recurring adjustments, necessary to present fairly the assets, liabilities and trust corpus of the Cross Timbers Royalty Trust at
September 30, 2013, and the distributable income and changes in trust corpus for the three- and nine-month periods ended September 30, 2013 and 2012, have been included. Distributable income for such interim periods is not necessarily
indicative of distributable income for the full year. The condensed financial statements as of September 30, 2013, and for the three-month and nine-month periods ended September 30, 2013 and 2012 have been subjected to a review by
PricewaterhouseCoopers LLP, the Trust's independent registered public accounting firm, whose report is included herein.

Report of Independent Registered Public Accounting Firm

To the Unitholders of Cross Timbers Royalty Trust and

Bank of
America, N.A., Trustee:

We have reviewed the accompanying condensed statement of assets, liabilities and trust corpus of Cross Timbers Royalty Trust (the
Trust) as of September 30, 2013, and the related condensed statements of distributable income and changes in trust corpus for the three-month and nine-month periods ended September 30, 2013 and 2012. These interim financial
statements are the responsibility of the Trustee.

We conducted our review in accordance with the standards of the Public Company Accounting Oversight
Board (United States). A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit
conducted in accordance with the standards of the Public Company Accounting Oversight Board (United States), the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express
such an opinion.

As described in Note 1, these financial statements were prepared on the modified cash basis of accounting, which is a comprehensive
basis of accounting other than accounting principles generally accepted in the United States of America.

Based on our review, we are not aware of any
material modifications that should be made to the accompanying condensed interim financial statements for them to be in conformity with the basis of accounting described in Note 1.

We previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the statement of assets, liabilities
and trust corpus as of December 31, 2012, and the related statements of distributable income and changes in trust corpus for the year then ended (not presented herein), and in our report dated March 8, 2013, we expressed an unqualified
opinion on those financial statements. In our opinion, the information set forth in the accompanying condensed statement of assets, liabilities and trust corpus as of December 31, 2012 is fairly stated in all material respects in relation to
the statement of assets, liabilities and trust corpus from which it has been derived.

CROSS TIMBERS ROYALTY TRUST

Notes to Condensed Financial Statements(Unaudited)



|1. | Basis of Accounting
|-- | -------------------

The financial statements of Cross Timbers Royalty Trust are
prepared on the following basis and are not intended to present financial position and results of operations in conformity with U.S. generally accepted accounting principles (GAAP):



| |  |  | Net profits income recorded for a month is the amount computed and paid by XTO Energy Inc., the owner of the underlying properties, to Bank of America, N.A., as trustee for the trust. XTO Energy is a wholly owned
subsidiary of Exxon Mobil Corporation. Net profits income consists of net proceeds received by XTO Energy from the underlying properties in the prior month, multiplied by net profit percentages of 90% for the 90% net profits interests, and 75% for
the 75% net profits interests.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Costs deducted in the calculation of net proceeds for the 90% net profits interests generally
include applicable taxes, transportation, marketing and legal costs, and do not include production expense or development costs. For the 75% net profits interests, costs deducted in the calculation of net proceeds include production expense,
development costs, applicable taxes, transportation, marketing and legal costs, operating charges and other costs.



| |  |  | Net profits income is computed separately for each of five conveyances under which the net profits interests were conveyed to the trust. If monthly costs exceed revenues for any conveyance, such excess costs must be
recovered, with accrued interest, from future net proceeds of that conveyance and cannot reduce net proceeds from the other conveyances.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| |  |  | The trustee routinely reviews the Trusts net profits interests in oil and gas properties for impairment whenever events or circumstances indicate that the carrying amount of an asset may not be recoverable. If an
impairment event occurs and it is determined that the carrying value of the Trusts net profits interests may not be recoverable, an impairment will be recognized as measured by the amount by which the carrying amount of the net profits
interests exceeds the fair value of these assets, which would likely be measured by discounting projected cash flows. There is no impairment of the assets as of September 30, 2013.

The financial statements of the trust differ from those prepared in conformity with U.S. GAAP because revenues are recognized when received
rather than accrued in the month of production, expenses are recognized when paid rather than when incurred, and certain cash reserves may be established by the trustee for contingencies which would not be recorded under U.S. GAAP. This
comprehensive basis of accounting other than U.S. GAAP corresponds to the accounting permitted for royalty trusts by the U.S. Securities and Exchange Commission, as specified by Staff Accounting Bulletin Topic 12:E, Financial Statements of Royalty
Trusts.

Most accounting pronouncements apply to entities whose financial statements are prepared in
accordance with U.S. GAAP, directing such entities to accrue or defer revenues and expenses in a period other than when such revenues were received or expenses were paid. Because the trusts financial statements are prepared on the modified
cash basis, as described above, most accounting pronouncements are not applicable to the trusts financial statements.

The initial
carrying value of the net profits interests of $61,100,449 represents XTO Energys historical net book value for the interests on February 12, 1991, the creation date of the trust. Amortization of the net profits interests is calculated on
a unit-of-production basis and is charged directly to trust corpus. Accumulated amortization was $49,102,772 as of September 30, 2013 and $48,567,720 as of December 31, 2012.



|2. | Federal Income Taxes
|-- | --------------------

For federal income tax purposes, the trust constitutes a fixed
investment trust that is taxed as a grantor trust. A grantor trust is not subject to tax at the trust level. The unitholders are considered to own the trusts income and principal as though no trust were in existence. The income of the trust is
deemed to have been received or accrued by each unitholder at the time such income is received or accrued by the trust and not when distributed by the trust.

Because the trust is a grantor trust for federal tax purposes, each unitholder is taxed directly on his proportionate share of income,
deductions and credits of the trust consistent with each such unitholders taxable year and method of accounting and without regard to the taxable year or method of accounting employed by the trust. The income of the trust consists primarily of
a specified share of the net profits from the sale of oil and natural gas produced from the underlying properties. During the first nine months of 2013, the trust incurred administration expenses and earned interest income on funds held for
distribution and for the cash reserve maintained for the payment of contingent and future obligations of the trust.

The net profits
interests constitute economic interests in oil and gas properties for federal tax purposes. Each unitholder is entitled to amortize the cost of the units through cost depletion over the life of the net profits interests or, if greater,
through percentage depletion equal to 15 percent of gross income. Unlike cost depletion, percentage depletion is not limited to a unitholders depletable tax basis in the units. Rather, a unitholder is entitled to a percentage depletion
deduction as long as the applicable underlying properties generate gross income. Unitholders may compute both percentage depletion and cost depletion from each property and claim the larger amount as a deduction on their income tax returns.

If a taxpayer disposes of any Section 1254 property (certain oil, gas, geothermal or other mineral property), and the adjusted
basis of such property includes adjustments for depletion deductions under Section 611 of the Internal Revenue Code (the Code), the taxpayer generally must recapture the amount deducted for depletion as ordinary income (to the
extent of gain realized on the disposition of the property). This depletion recapture rule applies to any disposition of property that was placed in service by the taxpayer after December 31, 1986. Detailed rules set forth in Sections 1.1254-1
through 1.1254-6 of the U.S. Treasury Regulations govern dispositions of property after March 13, 1995. The Internal Revenue Service likely will take the position that a unitholder must recapture depletion upon the disposition of a unit.

##### Table of Contents

Interest and net profits income attributable to ownership of units and any gain on the sale
thereof are considered portfolio income, and not income from a passive activity, to the extent a unitholder acquires and holds units as an investment and not in the ordinary course of a trade or business. Therefore, interest and net
profits income attributable to ownership of units generally may not be offset by losses from any passive activities.

Individuals may incur
expenses in connection with the acquisition or maintenance of trust units. These expenses may be deductible as miscellaneous itemized deductions only to the extent that such expenses exceed 2 percent of the individuals adjusted
gross income.

Under current law, the highest marginal U.S. federal income tax rate applicable to ordinary income of individuals is 39.6%,
and the highest marginal U.S. federal income tax rate applicable to long-term capital gains (generally, gains from the sale or exchange of certain investment assets held for more than one year) and qualified dividends of individuals is 20%. Such
marginal tax rates may be effectively increased by up to 1.2% due to the phaseout of personal exemptions and the limitations on itemized deductions. The highest marginal U.S. federal income tax rate applicable to corporations is 35%, and such rate
applies to both ordinary income and capital gains.

Section 1411 of the Code imposes a 3.8% Medicare tax on certain investment income
earned by individuals, estates, and trusts for taxable years beginning after December 31, 2012. For these purposes, investment income generally will include a unitholders allocable share of the trusts interest and royalty income
plus the gain recognized from a sale of trust units. In the case of an individual, the tax is imposed on the lesser of (i) the individuals net investment income from all investments, or (ii) the amount by which the individuals
modified adjusted gross income exceeds specified threshold levels depending on such individuals federal income tax filing status. In the case of an estate or trust, the tax is imposed on the lesser of (i) undistributed net investment
income, or (ii) the excess adjusted gross income over the dollar amount at which the highest income tax bracket applicable to an estate or trust begins.

Some trust units are held by middlemen, as such term is broadly defined in U.S. Treasury Regulations (and includes custodians, nominees,
certain joint owners, and brokers holding an interest for a customer in street name, collectively referred to herein as middlemen). Therefore, the trustee considers the trust to be a non-mortgage widely held fixed investment trust
(WHFIT) for U.S. federal income tax purposes. U.S. Trust, Bank of America Private Wealth Management, EIN: 56-0906609, Post Office Box 830650, Dallas, Texas, 75283-0650, telephone number 1-877-228-5084, email address
trustee1@crosstimberstrust.com, is the representative of the trust that will provide tax information in accordance with applicable U.S. Treasury Regulations governing the information reporting requirements of the trust as a WHFIT. Tax information is
also posted by the trustee at www.crosstimberstrust.com. Notwithstanding the foregoing, the middlemen holding trust units on behalf of unitholders, and not the trustee of the trust, are solely responsible for complying with the information
reporting requirements under the U.S. Treasury Regulations with respect to such trust units, including the issuance of IRS Forms 1099 and certain written tax statements. Unitholders whose trust units are held by middlemen should consult with such
middlemen regarding the information that will be reported to them by the middlemen with respect to the trust units.

Unitholders should
consult their tax advisors regarding trust tax compliance matters.

|3. | State Taxes
|-- | -----------

All revenues from the trust are from sources within Texas, Oklahoma or New
Mexico. Because it distributes all of its net income to unitholders, the trust has not been taxed at the trust level in New Mexico or Oklahoma. While the trust has not owed tax, the trustee is required to file a return with Oklahoma reflecting the
income and deductions of the trust attributable to properties located in that state, along with a schedule that includes information regarding distributions to unitholders. Texas does not impose a state income tax, so no part of the trusts
income will be subject to income tax at the trust level in Texas. Oklahoma and New Mexico tax the income of nonresidents from real property located within those states, and the trust has been advised by counsel that those states will each tax
nonresidents on income from the net profits interests located in those states. Oklahoma and New Mexico also impose a corporate income tax that may apply to unitholders organized as corporations (subject to certain exceptions for S corporations and
limited liability companies, depending on their treatment for federal tax purposes).

Texas imposes a franchise tax at a rate of 1% on
gross revenues less certain deductions, as specifically set forth in the Texas franchise tax statutes. Entities subject to tax generally include trusts and most other types of entities that provide limited liability protection, unless otherwise
exempt. Trusts that receive at least 90% of their federal gross income from designated passive sources, including royalties from mineral properties and other non-operated mineral interest income, and do not receive more than 10% of their income from
operating an active trade or business, generally are exempt from the Texas franchise tax as passive entities. The trust has been and expects to continue to be exempt from Texas franchise tax as a passive entity. Because the trust should
be exempt from Texas franchise tax at the trust level as a passive entity, each unitholder that is considered a taxable entity under the Texas franchise tax will generally be required to include its Texas portion of trust revenues in its own Texas
franchise tax computation. This revenue is sourced to Texas under provisions of the Texas Administrative Code providing that such income is sourced according to the principal place of business of the trust, which is Texas.

Each unitholder should consult his or her own tax advisor regarding state tax requirements, if any, applicable to such persons ownership
of trust units.



|4. | Contingencies
|-- | -------------

Several states have enacted legislation requiring state income tax
withholding from nonresident recipients of oil and gas proceeds. After consultation with its tax counsel, the trustee believes that it is not required to withhold on payments made to the unitholders. However, regulations are subject to change by the
various states, which could change this conclusion. Should amounts be withheld on payments made to the trust or the unitholders, distributions to the unitholders would be reduced by the required amount, subject to the filing of a claim for refund by
the trust or unitholders for such amount.



|5. | Excess Costs
|-- | ------------

Lower oil prices in January 2013 and increased costs related to the timing
of cash expenditures in January and March 2013 caused costs to exceed revenues by a total of $148,300 ($111,225 net to the trust) in January and March 2013 on properties underlying the Texas working interest. XTO advised the trustee that increased
costs related to the timing of cash expenditures caused costs to exceed revenues by a total of $103,563 ($77,672 net to the trust) in April 2013 on properties underlying the Texas working interest. However, these excess costs did not reduce net
proceeds from the remaining conveyances. Decreased costs in February 2013 and May 2013 and increased oil prices in June 2013 led to the partial recovery of excess costs, plus accrued interest, of $210,823 ($158,117 net to the trust) on properties
underlying the Texas working interest. Increased oil prices and decreased costs led to the full recovery of excess costs, plus accrued interest, of $42,445 ($31,834 net to the trust) in third quarter 2013. There were no excess costs remaining at
September 30, 2013.

##### Table of Contents

Lower oil prices and increased production expenses related to the timing of cash disbursements
caused costs to exceed revenues on properties underlying the Texas working interest in August 2012 by $218,168 ($163,626 net to the trust). However, these excess costs did not reduce net proceeds from the remaining conveyances. XTO advised the
trustee that increased oil prices and decreased production expenses led to the partial recovery of excess costs, plus accrued interest, on the properties underlying the Texas working interest in September 2012. Remaining excess costs totaled
$171,978 ($128,984 net to the trust) at the end of third quarter 2012.

Item 2. Trustees Discussion and Analysis.

The following discussion should be read in conjunction with the trustees discussion and analysis contained in the trusts 2012 Annual
Report on Form 10-K, as well as the condensed financial statements and notes thereto included in this Quarterly Report on Form 10-Q. The trusts Annual Report on Form 10-K, quarterly reports on Form 10-Q,
current reports on Form 8-K and all amendments to those reports are available on the trusts web site at www.crosstimberstrust.com.

Distributable Income

Quarter

For the quarter ended September 30, 2013, net profits income was $4,227,291 compared to $3,320,147 for third quarter 2012. This 27% increase in net
profits income is primarily the result of higher oil and gas prices ($1.2 million) and increased oil production ($0.3 million), partially offset by decreased gas production ($0.2 million), change in excess costs ($0.2 million) and increased
development costs ($0.1 million). See Net Profits Income on the following page.

After considering interest income of $86 and administration
expense of $62,813, distributable income for the quarter ended September 30, 2013 was $4,164,564, or $0.694094 per unit of beneficial interest. Administrative expense for the quarter increased $10,192 from the prior year quarter. For third
quarter 2012, distributable income was $3,267,606, or $0.544601 per unit. Distributions to unitholders for the quarter ended September 30, 2013 were:

Nine Months

For the nine months ended September 30, 2013, net profits income was $10,244,910 compared to $11,658,423 for the same 2012 period. This 12% decrease in
net profits income is primarily the result of increased development costs ($0.8 million), decreased gas production ($0.6 million) and lower oil prices ($0.6 million), partially offset by increased oil production ($0.4 million) and higher gas prices
($0.2 million). See Net Profits Income below.

After considering interest income of $203 and administration expense of $323,843, distributable
income for the nine months ended September 30, 2013 was $9,921,270, or $1.653545 per unit of beneficial interest. Administrative expense for the nine months ended September 30, 2013 increased $5,250 from the prior year nine-month period.
For the nine months ended September 30, 2012, distributable income was $11,340,072, or $1.890012 per unit.

Net Profits Income

Net profits income is recorded when received by the trust, which is the month following receipt by XTO Energy and generally two months after oil production and
three months after gas production. Net profits income is generally affected by three major factors:



| |  |  | oil and gas sales volumes,
| | - |  | --------------------------



| |  |  | oil and gas sales prices, and
| | - |  | -----------------------------



| |  |  | costs deducted in the calculation of net profits income.
| | - |  | --------------------------------------------------------

Because properties underlying the 90% net profits
interests are royalty and overriding royalty interests, the calculation of net profits income from these interests only includes deductions for production and property taxes, legal costs, and marketing and transportation charges. In addition to
these costs, the calculation of net profits income from the 75% net profits interests includes deductions for production expense and development costs since the related underlying properties are working interests.

|(a) | Because of the interval between time of production and receipt of royalty income by the trust, (1) oil and gas sales for the quarter ended September 30 generally represent oil production for the period
May through July and gas production for the period April through June and (2) oil and gas sales for the nine-months ended September 30 generally represent oil production for the period November through July and gas production for the
period October through June.
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(b) | Oil and gas sales volumes are allocated to the net profits interests based upon a formula that considers oil and gas prices and the total amount of production expense and development costs. As product prices
change, the trusts share of the production volumes is impacted as the quantity of production to cover expenses in reaching the net profits break-even level changes inversely with price. As such, the underlying property production volume
changes may not correlate with the trusts net profit share of those volumes in any given period. Therefore, comparative discussion of oil and gas sales volumes is based on the underlying properties.
|--- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(c) | Production expense is primarily from seven working interest properties in the 75% net profits interest. Six of these properties are not operated by XTO Energy or ExxonMobil. Production expense includes an
overhead charge which is deducted and retained by the operator. As of September 30, 2013, this charge was $35,947 per month (including monthly overhead charges of $5,135 which XTO Energy deducts as operator of the Hewitt Unit) and is subject to
adjustment each May based on an oil and gas industry index.

##### Table of Contents

The following are explanations of significant variances on the underlying properties from third quarter 2012 to
third quarter 2013 and from the first nine months of 2012 to the comparable period in 2013:

Sales Volumes

Oil

Oil sales volumes increased 7% for third quarter 2013
and 4% for the first nine months of 2013 as compared with the same 2012 periods primarily because of the timing of cash receipts, partially offset by natural production decline.

Gas

Gas sales volumes decreased 5% for third quarter
2013 and 7% for the first nine months of 2013 as compared with the same 2012 periods primarily because of the timing of cash receipts and natural production decline, partially offset by increased production from new wells and workovers.

The estimated rate of natural production decline on the underlying oil and gas properties is approximately 6% to 8% a year.

Sales Prices

Oil

The average oil price increased 13% to $92.63 per Bbl for the third quarter and decreased 6% to $85.67 per Bbl for the nine-month period. Oil prices are
expected to remain volatile. The third quarter 2013 oil price is primarily related to production from May through July 2013, when the average NYMEX price was $98.41 per Bbl. The average NYMEX price for August and September 2013 was $106.52 per Bbl.
At October 22, 2013, the average NYMEX futures price for the following twelve months was $96.67 per Bbl.

Gas

Gas prices for the third quarter increased 37% to $6.72 per Mcf and for the nine-month period increased 2% to $6.23 per Mcf. Natural gas prices are affected by
the level of North American production, weather, crude oil and natural gas liquids prices, the U.S. economy, storage levels and import levels of liquefied natural gas. Natural gas prices are expected to remain volatile. The third quarter 2013 gas
price is primarily related to production from April through June 2013, when the average NYMEX price was $4.09 per MMBtu. The average NYMEX price for July through September 2013 was $3.58 per MMBtu. At October 22, 2013, the average NYMEX futures
price for the following twelve months was $3.78 per MMBtu.

##### Table of Contents

Costs

Taxes, Transportation and Other

Taxes, transportation and
other increased 16% for the third quarter primarily because of increased oil and gas production taxes and other deductions related to higher oil and gas revenues. Taxes, transportation and other decreased 10% for the nine-month period primarily
because of decreased oil and gas production taxes and other deductions related to lower oil and gas revenues.

Production Expense

Production expense increased 5% for the third quarter primarily because of increased power and fuel and labor costs, partially offset by decreased outside
operated and field costs. Production expense increased 6% for the nine-month period primarily because of increased power and fuel, non-operated overhead and labor costs, partially offset by decreased repairs and maintenance costs.

Development Costs

Development costs increased 27% for
the third quarter and 97% for the nine-month period primarily because of the timing of expenditures and increased activity and costs related to non-operated Texas and Oklahoma oil properties underlying the 75% net profits interest.

Excess Costs

Lower oil prices in January 2013 and
increased costs related to the timing of cash expenditures in January and March 2013 caused costs to exceed revenues by a total of $148,300 ($111,225 net to the trust) in January and March 2013 on properties underlying the Texas working interest.
XTO advised the trustee that increased costs related to the timing of cash expenditures caused costs to exceed revenues by a total of $103,563 ($77,672 net to the trust) in April 2013 on properties underlying the Texas working interest. However,
these excess costs did not reduce net proceeds from the remaining conveyances. Decreased costs in February 2013 and May 2013 and increased oil prices in June 2013 led to the partial recovery of excess costs, plus accrued interest, of $210,823
($158,117 net to the trust) on properties underlying the Texas working interest. Increased oil prices and decreased costs led to the full recovery of excess costs, plus accrued interest, of $42,445 ($31,834 net to the trust) in third quarter 2013.
There were no excess costs remaining at September 30, 2013.

Lower oil prices and increased production expenses related to the timing of cash
disbursements caused costs to exceed revenues on properties underlying the Texas working interest in August 2012 by $218,168 ($163,626 net to the trust). However, these excess costs did not reduce net proceeds from the remaining conveyances. XTO
advised the trustee that increased oil prices and decreased production expenses led to the partial recovery of excess costs, plus accrued interest, on the properties underlying the Texas working interest in September 2012. Remaining excess costs
totaled $171,978 ($128,984 net to the trust) at the end of third quarter 2012.

Contingencies

Several states have enacted legislation requiring state income tax withholding from nonresident recipients of oil and gas proceeds. After consultation with its
tax counsel, the trustee believes that it is not required to withhold on payments made to the unitholders. However, regulations are subject to change by the various states, which could change this conclusion. Should amounts be withheld on payments
made to the trust or the unitholders, distributions to the unitholders would be reduced by the required amount, subject to the filing of a claim for refund by the trust or unitholders for such amount.

Forward-Looking Statements

Statements in this report
relating to future plans, predictions, events or conditions are forward-looking statements. All statements other than statements of historical fact included in this Form 10-Q including, without limitation, statements regarding the net profits
interests, underlying properties, development activities, development, production and other costs and expenses, oil and gas prices and differentials to NYMEX prices, distributions to unitholders and industry and market conditions, are
forward-looking statements that are subject to risks and uncertainties which are detailed in Part I, Item 1A of the trusts Annual Report on Form 10-K for the year ended December 31, 2012, which is incorporated by this reference as
though fully set forth herein. XTO Energy and the trustee assume no duty to update these statements as of any future date.

Item 3. Quantitative and Qualitative Disclosures about Market Risk.

There have been no material changes in the trusts market risks from the information disclosed in Part II, Item 7A of the trusts Annual Report
on Form 10-K for the year ended December 31, 2012.

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 trusts disclosure controls and
procedures pursuant to Exchange Act Rules 13a-15 and 15d-15. Based upon that evaluation, the trustee concluded that the trusts disclosure controls and procedures are effective in recording, processing, summarizing and reporting, on a timely
basis, information required to be disclosed by the trust in the reports that it files or submits under the Securities Exchange Act of 1934 and are effective in ensuring that information required to be disclosed by the trust in the reports that it
files or submits under the Securities Exchange Act of 1934 is accumulated and communicated to the trustee to allow timely decisions regarding required disclosure. In its evaluation of disclosure controls and procedures, the trustee has relied, to
the extent considered reasonable, on information provided by XTO Energy. 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.
