T H E T R U S T The principal asset of the San Juan Basin Royalty Trust (the Trust) consists of a
75% net overriding royalty interest (the Royalty) carved out of certain oil and gas leasehold and
royalty interests (the Underlying Properties) in properties located in the San Juan Basin of
northwestern New Mexico. The Units of beneficial interest of the Trust (the Units) are traded on
the New York Stock Exchange under the symbol SJT.

To Unit Holders We are pleased to present the 2010 Annual Report of the San Juan Basin Royalty
Trust. The report includes a copy of the Trusts Annual Report on Form 10-K filed with the
Securities and Exchange Commission (the Commission) for the year ended December 31, 2010, without
exhibits. The Form 10-K contains important information concerning the Underlying Properties, as
defined below, including the oil and gas reserves attributable to the 75% net overriding royalty
interest owned by the Trust. Production figures provided in this letter and in the Trustees
Discussion and Analysis are based on information provided by Burlington Resources Oil & Gas Company
LP (BROG), the current owner of the Underlying Properties and the successor, through a series of
assignments and mergers, to Southland Royalty Company (Southland). The Trust was established in
November 1980 by Southland. Pursuant to the Indenture that governs the operations of the Trust,
Southland conveyed to the Trust a 75% net overriding royalty interest (equivalent to a net profits
interest) (the Royalty), carved out of Southlands oil and gas leasehold and royalty interests
(the Underlying Properties) in properties in the San Juan Basin of northwestern New Mexico. The
Royalty constitutes the principal asset of the Trust. Under the Indenture governing the Trust, the
function of Compass Bank, as Trustee, is to collect the net proceeds attributable to the Royalty
(Royalty Income), pay all expenses and charges of the Trust, and then distribute the remaining
available income to the Unit holders. Income distributed to Unit holders in 2010 was $78,355,835 or
$1.681139 per Unit. Distributable income for 2010 consisted of Royalty Income of $79,971,751 plus
interest income of $309,437, less administrative expenses of $1,925,353. Information about the
Trusts estimated proved reserves of gas, including coal seam gas, and of oil as well as the
present value of net revenues discounted at 10% can be found in Item 2 of the accompanying Form
10-K. Certain Royalty Income is generally considered portfolio income under the passive loss rules
of the Internal Revenue Code of 1986, as amended. Therefore, Unit holders should generally not
consider the taxable income from the Trust to be passive income in determining net passive income
or loss. Unit holders should consult their tax advisors for further information. Unit holders of
record will continue to receive an individualized tax information letter for each of the quarters
ending March 31, June 30 and September 30, 2011, and both an individualized tax information letter
and a Form 1099 for the year ending December 31, 2011. Unit holders owning Units in nominee name
may obtain monthly tax information from the Trusts Web site or from the Trustee upon request. For
the readers convenience, a glossary of definitions used in this report can be found on the inside
back cover. Please visit our Web site at www.sjbrt.com to access news releases, reports, Commission
filings and tax information. The San Juan Basin Royalty Trust observed its 30th anniversary in
November 2010. To celebrate the Trusts 30-year history, we pulled out copies of the annual report
for each year. We hope you will enjoy the 30 annual report covers featured in our report design for
this year. Compass Bank, Trustee By: Lee Ann AndersonLee Ann Anderson, Vice President and Senior
Trust Officer

D E S C R I P T I O N O F T H E P R O P E R T I E S The principal asset of the Trust is a 75% net
overriding royalty interest (the Royalty) carved out of certain working, royalty and other
leasehold interests (the Underlying Properties) owned by BROG in oil and gas properties located
in the San Juan Basin, and more particularly in San Juan, Rio Arriba and Sandoval Counties of
northwestern New Mexico. The Underlying Properties consist of working interests, royalty interests,
overriding royalty interests and other contractual rights in 151,900 gross (119,000 net) acres and
4,016 gross (1,173 net) wells, calculated on a well bore basis and not including multiple
completions as separate wells. The Underlying Properties have historically produced gas primarily
from conventional wells drilled to three major formations: the Pictured Cliffs, the Mesaverde and
the Dakota, ranging in depth from 1,500 to 8,000 feet. The characteristics of these reservoirs
result in the wells having very long productive lives. A production index for oil and gas
properties is derived by dividing remaining reserves by current production. Based upon the reserve
report prepared by the Trusts independent petroleum engineers as of December 31, 2010, the
production index for the Underlying Properties is estimated to be approximately 8.3 years. The
production index is subject to change from year to year based on reserve revisions and production
levels and is not presented as an estimate of the life expectancy of the Trust. Among the factors
considered by engineers in estimating remaining reserves of natural gas is the applicable sales
price for gas. As the sales price increases, the producer can justify expending higher lifting
costs and therefore reasonably expect to recover more of the known reserves. Accordingly, as gas
prices rise, the production index increases and vice versa. In addition to gas from conventional
wells, the Underlying Properties also produce gas from coal seam wells completed to the Fruitland
Coal formation. The process of removing coal seam gas is often referred to as degasification or
desorption. Millions of years ago, natural gas was generated in the process of coal formation and
absorbed into the coal. Water later filled the natural fracture system. When the water is removed
from the natural fracture system, reservoir pressure is lowered and the gas desorbs from the coal.
The desorbed gas then flows through the fracture system and is produced at the well bore. The
volume of formation water production typically declines with time and the gas production may
increase for a period of time before starting to decline. In order to dispose of the formation
water, surface facilities including pumping units are required. The price of coal seam gas is
typically lower than the price of conventional gas. This is because the heating value of coal seam
gas is much lower than that of conventional gas due to (a) ever increasing percentages of carbon
dioxide in coal seam gas (carbon dioxide has no heating value), and (b) the absence of heavier
hydrocarbons such as ethanes, propanes, and butanes which are present in conventional gas.
Furthermore, the processing fees for coal seam gas are typically higher than the processing fees
for conventional gas due to the cost of extracting the carbon dioxide. In February 2002, BROG
informed the Trust that the New Mexico Oil Conservation Division (the OCD) had approved plans for
80-acre infill drilling of the Dakota formation in the San Juan Basin. In July 2003, the OCD
approved 160-acre spacing in the Fruitland Coal formation. Eighty-acre spacing has been permitted
in the Mesaverde formation since 1997. BROG is participating in an ongoing study involving test
wells completed to the Mesaverde and/or Dakota formations, with some of the test wells drilled on a
less than 80-acre spacing basis. In 2009, BROG drilled and completed a horizontal well in the
Fruitland C
oal formation on acreage that is burdened by the Royalty. BROG indicates that it will
continue its program of horizontal drilling in 2011, with one horizontal well planned to be drilled
in the Fruitland Coal formation. While a horizontal well costs more to drill than a more
traditional vertical well, the new technology enables the operator to reach additional reserves in
areas not fully exploited. BROG reports it anticipates operating approximately four drilling rigs
in the San Juan Basin during 2011 and that emphasis will be placed on re-working existing wells as
distinguished from the drilling of new wells. The Federal Energy Regulatory Commission is primarily
responsible for federal regulation of natural gas. For a further discussion of gas pricing, gas
purchasers, gas production and regulatory matters affecting gas production, see Item 2,
Properties, in the accompanying Form 10-K.
