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.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Interest income, interest to be received and distribution payable to unitholders include interest to be earned on net profits income from the monthly
record date (last business day of the month) through the date of the next distribution to unitholders.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Trust expenses are recorded based on liabilities paid and cash reserves established by the trustee for liabilities and contingencies.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Distributions to unitholders are recorded when declared by the trustee.
| | - |  | -----------------------------------------------------------------------

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.

##### Table of Contents

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 $47,911,631 as of
March 31, 2012 and $47,684,709 as of December 31, 2011.



|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 quarter of 2012, 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 if the adjusted basis of such property includes adjustments for deductions for depletion under Section 611 of the Internal
Revenue 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.

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.

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 trustee@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 either 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 unless otherwise exempt and most other types of entities that provide limited liability protection. 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 exempt from Texas franchise tax as a passive entity. Because the trust has been 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 has been required to include its Texas portion of trust revenues in its own Texas franchise tax computation. This revenue has been 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.

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 2011 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

For the quarter ended March 31, 2012, net profits income was $4,376,980 compared to $4,350,853 for first quarter 2011. This 1% increase in net
profits income is the result of higher oil and gas prices ($1.0 million) and decreased development costs ($0.1 million), partially offset by decreased oil and gas production ($0.8 million) and increased production expenses ($0.2 million). See
Net Profits Income on following page.

After considering interest income of $86 and administration expense of $127,842,
distributable income for the quarter ended March 31, 2012 was $4,249,224, or $0.708204 per unit of beneficial interest. Administration expense for the quarter increased $1,069 from the prior year quarter. For first quarter 2011, distributable
income was $4,224,174, or $0.704029 per unit. Distributions to unitholders for the quarter ended March 31, 2012 were:

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, oil and gas sales for the quarter ended March 31 generally
represent oil production for the period November through January and gas production for the period October through December.
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(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. Five 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 March 31, 2012, this charge was $34,184 per month (including monthly overhead charges of $2,638 which XTO Energy deducts as
operator of the Penwell Unit and $4,507 which ExxonMobil 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 first quarter 2011
to first quarter 2012:

Sales Volumes

Oil

Oil sales volumes decreased 7% from first quarter 2011 to first quarter 2012 primarily
because of natural production decline.

Gas

Gas sales volumes decreased 14% from first quarter 2011 to first quarter 2012 primarily because of natural production decline and the timing of cash receipts.

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 first quarter 2012 average oil price was $93.41 per Bbl, a 18% increase from the first quarter 2011 average price of $79.31 per Bbl. Oil prices are
expected to remain volatile. The first quarter 2012 oil price is primarily related to production from November 2011 through January 2012, when the average NYMEX price was $98.53 per Bbl. The average NYMEX price for February and March 2012 was
$104.32 per Bbl. At April 18, 2012, the average NYMEX futures price for the following twelve months was $104.13 per Bbl.

Gas

The first quarter 2012 average gas price was $7.41 per Mcf, a 11% increase from the first quarter 2011 average price of $6.69 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 first quarter 2012 gas price is primarily related to production from October through December 2011, when the average NYMEX price was $3.55 per MMBtu. The average NYMEX price for January through March 2012 was $2.74 per MMBtu. At
April 18, 2012, the average NYMEX futures price for the following twelve months was $2.61 per MMBtu.

Costs

Taxes, Transportation and Other

Taxes,
transportation and other increased 2% for the first quarter primarily because of increased oil production taxes related to higher oil revenues and increased property taxes related to the timing of expenditures, partially offset by decreased gas
production taxes and other deductions related to lower gas revenues.

##### Table of Contents

Production Expense

Production expense increased 29% for the first quarter primarily because of increased repairs and maintenance, outside operated and power and fuel costs.

Development

Development costs decreased
46% for the first quarter primarily because of decreased activity and costs related to Texas and Oklahoma properties underlying the 75% net profits interests.

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, 2011, 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, 2011.

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 timely 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.
