                             1996 TAX INFORMATION

READING THE INCOME AND EXPENSE SCHEDULES

  The accompanying income and expense schedules reflect tax information
attributable to Sabine Royalty Trust (the "Trust") for 1996. This information
has been assembled on a per Unit basis and is expressed in decimal fractions
of one dollar. A cumulative schedule for the twelve months ended December 31,
1996, and separate noncumulative schedules for the months of January through
December 1996 are enclosed. Separate depletion schedules are enclosed which
provide the necessary information for Unit holders to compute cost depletion
with respect to their interests in the Trust.

IDENTIFYING WHICH INCOME AND EXPENSE SCHEDULES TO USE

  Pursuant to the terms of the Trust agreement and the escrow agreement, the
Trust receives income and incurs expenses only on Monthly Record Dates.
Furthermore, only Unit holders of record on Monthly Record Dates are entitled
to cash distributions. On the basis of these agreements, both cash and accrual
basis Unit holders should be considered as realizing income and incurring
expenses only on Monthly Record Dates. Therefore, if you were not the Unit
holder of record of the Units on a specified Monthly Record Date, you should
not use the tax information for the month in which that Monthly Record Date
falls. A table of Monthly Record Dates and cash distributions per Unit is
included on page 3.

  The appropriate schedules to be used by a Unit holder will depend upon (i)
the date the Unit holder became a holder of record of the Units, (ii) if
applicable, the date the Unit holder ceased to be the holder of record of the
Units, and (iii) the tax year end of the Unit holder. For instance, a Unit
holder reporting on the calendar year basis who acquired Units and became a
Unit holder of record on June 17, 1996 and who still owned only those Units on
December 16, 1996 must use each of the separate monthly schedules for June
through December 1996, and Depletion Schedule XVI for such Units. However,
Unit holders reporting on a calendar year basis who became Unit holders of
record prior to January 16, 1996 and who continued to own only those Units on
December 16, 1996, must use only the cumulative schedule for calendar year
1996 and the appropriate depletion schedule(s).

APPLYING THE DATA FROM THE INCOME AND EXPENSE SCHEDULES

  The tax data, other than depletion, specifically applicable to a Unit holder
may be determined by multiplying the appropriate decimal fractions times the
number of Units owned. Unit holders who must use the separate monthly income
and expense schedules should combine the individual income and expense factors
from the monthly schedules for each month during which the Units were owned on
a Monthly Record Date. For a worksheet approach to computing these decimal
fractions, see the Supplement to Tax Computation Worksheet on page 5.

COMPUTING DEPLETION

  Depletion schedules are included which provide information for Unit holders
to compute cost depletion deductions with respect to their interests in the
Trust. To compute depletion for any taxable period, Unit holders should
multiply the depletion factor indicated on the relevant schedule times their
original tax basis in the respective Unit(s), reduced by the cost depletion
that was allowable as a deduction (whether or not deducted) in prior calendar
years during which they owned the Units. A factor for percentage depletion is
not included, as cost depletion exceeded the percentage depletion calculated.

  Noncorporate Unit holders who acquired Units in the original distribution
from Sabine Corporation ("Sabine") should use Depletion Schedule I to compute
1996 depletion on those Units. Corporate Unit holders that acquired Units in
the original distribution from Sabine should use Depletion Schedule II to
compute 1996 depletion on those Units. The proper depletion schedule to be
utilized for Units owned is reflected below.

</TABLE>

  As discussed at page A-3 in the back portion of this booklet, the composite
depletion factors are determined on the basis of a weighted average ratio of
current production from each Trust property to the estimated future production
from such property. This method of weighting the depletion factors permits the
presentation of a single depletion factor for all Unit holders acquiring Units
during a period in which there is no substantial change in the relative fair
market values of the Trust properties. Primarily as a result of the decline in
oil prices which occurred during 1986, there was a change in the relative fair
market values of the Trust properties. Accordingly, two mutually exclusive
depletion schedules are included herein reflecting the composite depletion
factors required to compute depletion for Units acquired in 1986. The proper
depletion schedule to use in computing 1996 depletion is dependent upon the
date upon which the Units were acquired as reflected in the preceding
paragraph.

  The amount of depletion attributable to a specific state may be determined
by multiplying the depletion factor indicated for the particular state times
the Federal tax basis in the Unit(s) held, reduced by prior calendar years'
allowable Federal depletion, if any. The Federal and state depletion factors
contained on Depletion Schedule I through Depletion Schedule XV are presented
on a cumulative basis for 1996. However, the Federal and state depletion
factors contained on Depletion Schedule XVI are summarized separately; and the
state factors are presented on a noncumulative basis. If you are using
Depletion Schedule XVI for your state income tax return(s), you may either
calculate the applicable state depletion for each month and add the monthly
depletion amounts together, or you may add together the applicable monthly
depletion factors for the relevant state and multiply this created composite
depletion factor times your adjusted basis in your Units. The result should be
the same using either method.

  Different depletion schedules may be required to be used for Units acquired
in different years by a Unit holder. Therefore, Unit holders are encouraged to
maintain records indicating the date of acquisition and the acquisition price
for each Unit or lot of Units acquired.

SALE OR EXCHANGE OF UNITS

  A discussion concerning the tax consequences associated with the sale or
exchange of Units is presented on page A-4 in the back portion of this
booklet.

CLASSIFICATION OF INVESTMENT

  Tax Reform measures enacted in 1986 and 1987 require items of income and
expense to be categorized as "passive," "active" or "portfolio" in nature. An
explanation of the application of these rules to the items of income and
expense reported by the Trust are contained on page A-1 in the back portion of
this booklet.

NONRESIDENT FOREIGN UNIT HOLDERS

  Nonresident alien individual and foreign corporation Unit holders ("Foreign
Taxpayer(s)") are subject to special tax rules with respect to their
investments in the Trust. These rules are outlined beginning on page A-3 in
the back portion of this booklet.

BACKUP WITHHOLDING

  Unit holders who have had amounts withheld in 1996 pursuant to the Federal
backup withholding provisions should have received a Form 1099-MISC from the
Trust. The Form 1099-MISC reflects the total Federal income tax withheld from
distributions. The amount reported on the Form 1099-MISC should not be
included as additional income in computing taxable income, as such amount is
already included in the per Unit income items on the income and expense
schedules. The Federal income tax withheld, as reported on the Form 1099-MISC,
should be considered as a credit by the Unit holder in computing any Federal
income tax liability. Individual Unit holders should include the amount of
backup withholding on line 52 of page 2 of the 1996 Form 1040. For a further
discussion of backup withholding, see page A-4 in the back portion of this
booklet.

STATE INCOME TAX

  Since the Trust holds royalty interests and receives income that is
attributable to various states, Unit holders may be obligated to file a return
and may have a tax liability in states in addition to their state of
residence. The accompanying schedules have been prepared in such a manner that
income and deductions attributable to the various states may be determined by
each Unit holder. State income tax matters are more fully discussed on page A-
5 in the back portion of this booklet.

TABLE OF 1996 MONTHLY RECORD DATES AND CASH DISTRIBUTIONS PER UNIT

  Unit holders, as reflected in the transfer books of the Trust on a Monthly
Record Date, received the following per Unit cash distributions for 19956 The
per Unit cash distributions reflected below have not been reduced by any taxes
that may have been withheld from distributions to Foreign Taxpayers or from
distributions to Unit holders subject to the Federal backup withholding rules.
The distribution checks were dated and mailed on the corresponding Date
Payable.

    Worksheet for each block of Units acquired at different times. Only the
    total of each item of income and expense obtained by adding the separate
    Tax Computation Worksheet totals, if more than one is required, should be
    reported on your applicable 1996 income tax returns.
(2) If you did not become a Unit holder of record of any Unit(s) or did not
    cease to be a Unit holder of record of any Unit(s) during the period from
    January 16, 1996 through December 16, 1996, then the amounts reflected on
    the cumulative schedule for 1996 should be used to complete Part I. If any
    Units were held of record for only part of the period defined above, the
    Supplement to Tax Computation Worksheet on page 5 should be used to derive
    the income and expense factors to be inserted in column B.
(3) The Trustee believes that individual Unit holders owning the Units as an
    investment should report the amounts determined in this manner. The U.S.
    Corporation Income Tax Return (Form 1120) does not require that royalty
    income and related expenses be separately identified on any specific
    schedules. Note: Schedule D should be utilized to report the Sale of Units
    acquired before January 1, 1987. (See "Sale or Exchange of Units" on page
    A-4.)
(4) The appropriate depletion schedule(s) to be utilized is generally
    dependent upon the date on which the Units were acquired. See "Computing
    Cost Depletion" on page 1 to determine the proper schedule(s) to be used.
(5) Cost depletion allowable in prior calendar years cannot be computed from
    the schedules contained in this booklet. Depletion schedules contained in
    prior years' Sabine Royalty Trust Tax Information Booklet(s) should be
    used in order to determine the appropriate cost depletion amount(s)
    allowable in prior calendar years.
(6) The adjusted basis is equal to the cost or other basis of the Unit(s) less
    the cost depletion allowable from the date of acquisition through the date
    of sale (whether or not deducted).

                   FOR UNITS HELD FOR ONLY PART OF THE YEAR

  This worksheet should be used by Unit holders who became holders of record
of Units or ceased to be holders of record of Units during the period from
January 16, 1996 through December 16, 1996. This worksheet is designed to
assist Unit holders in determining the proper income and expense factors to be
used on the Tax Computation Worksheet-- Part I, under the heading entitled
"Amounts Per Unit from Appropriate Schedule(s)". In order to complete this
schedule, Unit holders should insert only the individual income and expense
factors from the monthly schedules (pages 7-18) for each month during which
the Units were owned on a Monthly Record Date. (See page 3 for a list of
Monthly Record Dates).

                             SABINE ROYALTY TRUST

              DISCUSSION OF TAX CONSIDERATIONS PERTAINING TO THE
                  OWNERSHIP OF UNITS IN SABINE ROYALTY TRUST


  The tax law requires individuals, estates, trusts, closely held C
corporations and personal service corporations to categorize income and
expense into one of three classes, "active," "portfolio" or "passive", based
upon the nature of the activity and the involvement of the taxpayer in such
activity. Since the Trust is a grantor trust, the Unit holders are deemed to
hold the investment in the royalty interests directly and the proper
classification of the Trust income and expense will be dependent upon the
relevant facts and circumstances of each Unit holder. Generally, income or
loss resulting from an interest in the Trust is properly classified as
portfolio and as such can be reported as directed on the tax computation
worksheet (page 4). However, under certain limited circumstances a different
classification may be appropriate, accordingly Unit holders should consult
their tax advisor concerning this matter.

TAXATION OF THE ORIGINAL DISTRIBUTION OF UNITS

  A detailed discussion of the Federal income tax consequences arising from
the original distribution of Units was included in the 1983 tax information
booklet of the Trust. The majority of that discussion was applicable only to
Unit holders who received Units in the distribution from Sabine Corporation
("Sabine"). Unit holders who desire a copy of this material may obtain copies
of the information by writing the Trustee of the Trust at:

      Sabine Royalty Trust
      1983 Tax Booklet
      NationsBank of Texas N.A., Trustee
      P.O. Box 830650
      Dallas, Texas 75283-0650

TAX BACKGROUND INFORMATION

  Sabine received a private letter ruling from the Internal Revenue Service,
dated May 2, 1983 (the "Ruling"), concerning certain tax considerations
relevant to the creation and continued existence of the Trust. Pursuant to the
Ruling, the Trust is classified for Federal income tax purposes as a "grantor
trust" and not as an association taxable as a corporation. A grantor trust is
not subject to Federal income tax. Instead, its beneficiaries (the Unit
holders in the case of the Trust) are generally considered to own the trust's
income and principal as though no trust were in existence. A grantor trust
simply files an information return reflecting all items of income and/or
deductions that will be included in the returns of the beneficiaries.
Accordingly, each Unit holder of the Trust is taxable on his pro rata share of
the Trust income and/or deductions.

  The income received or accrued and deductions paid or incurred by the Trust
are deemed to be received or accrued and paid or incurred, respectively, by
each Unit holder at the same time as the Trust. Thus, the taxable year for
reporting a Unit holder's share of the Trust's income and deductions is
controlled by the Unit holder's taxable year and method of accounting rather
than the taxable year and method of accounting of the Trust. For example, a
cash basis Unit holder should recognize income attributable to his Units as
such income is received by the Trust; and deductions attributable to his Units
should be claimed when such deductions are paid by the Trust.

 Effect of Escrow Arrangement

  The assets of the Trust include royalty and mineral interests in certain
producing and proved undeveloped oil and gas properties (the "Properties"),
which constitute economic interests in gross production of oil, gas and other
minerals free of the costs of production. The Properties are located in six
states and were not carved out of any of Sabine's working interests in
effecting the distribution. In order to facilitate creation of the Trust and
avoid the administrative expense and inconvenience of daily reporting to Unit
holders, the conveyances by Sabine of the Properties located in five of the
six states provided for the execution of an escrow agreement by Sabine, the
Trustee and InterFirst Bank Dallas, N.A., in its capacity as escrow agent. The
conveyances by Sabine of the Properties located in Louisiana provided for the
execution of a substantially identical escrow agreement by Sabine and a
Louisiana bank, in the capacities of escrow agent and of trustee under Sabine
Louisiana Royalty Trust. Sabine Louisiana Royalty Trust, the sole beneficiary
of which is the Trust, was established in order to avoid uncertainty under
Louisiana law as to the legality of the Trustee's holding record title to the
Properties located in Louisiana.

  Pursuant to the terms of the escrow agreement and the conveyances of the
Properties by Sabine, the proceeds of production from the Properties for each
calendar month, and interest thereon, are collected by the escrow agents and
are paid to and received by the Trust only on the next Monthly Record Date.
The escrow agents have agreed to endeavor to assure that they incur and pay
expenses for each calendar month only on the Monthly Record Date. The Trust
Agreement also provides that the Trustee is to endeavor to assure that income
of the Trust will be accrued and received and expenses of the Trust will be
incurred and paid only on each Monthly Record Date. Assuming the escrow
arrangement is recognized for Federal income tax purposes and the Trustee and
the escrow agents are able to control the timing of income and expenses, as
stated above, both cash and accrual basis Unit holders will be treated as
realizing income only on each Monthly Record Date. The Trustee is treating the
escrow arrangement as effective for tax purposes and the accompanying tax
information has been presented accordingly.

  If the escrow arrangement is not recognized for Federal income tax purposes,
a mismatching of income and deductions could occur between a transferor and a
transferee upon the sale or exchange of Units. In addition, the Trustee would
be required to report the proceeds from production, interest income thereon
and any deductions to the Unit holders on a daily basis, resulting in a
substantial increase in the administrative expenses of the Trust.

DEPLETION

 Cost Depletion

  Pursuant to the previously mentioned Ruling, each Unit holder is entitled to
deduct cost depletion with respect to his pro rata interest in the Properties.
This cost depletion deduction is computed by reference to the Unit holder's
basis in each of his Units.

  The deduction for cost depletion must be computed by a Unit holder with
respect to each separate property in the Trust. A Unit holder's tax basis in
each separate property generally must be determined at the time each Unit is
acquired by allocating such Unit holder's cost in each Unit among all
properties in the Trust based on their relative fair market values. However, a
corporate Unit holder that acquired Units in the distribution from Sabine must
determine its tax basis in each separate property in the Trust at the time of
the distribution by reference to Sabine's tax basis in each separate property
included in the distribution. The cost depletion deduction attributable to
each separate property is calculated for a taxable year by multiplying the tax
basis of the property times the decimal derived when estimated total

(SRT 1996 TAX)

                                      A-2
<PAGE>

equivalent units of production (barrels of oil and MCF's of gas) expected to
be recovered from the property as of the beginning of the taxable year is
divided into the number of equivalent units produced and sold from such
property during the taxable year. The resulting deduction for cost depletion
cannot exceed the adjusted tax basis in the property. The composite depletion
factors presented herein were derived in a manner that encompasses this
separate property concept.

 Percentage Depletion

  Prior to the Revenue Reconciliation Act of 1990, Unit holders were
prohibited from claiming percentage depletion on transferred proven oil and
gas properties. Since substantially all of the properties were "proven
properties" on the date of the original distribution, the percentage depletion
deduction has limited applicability to Unit holders which became Unit holders
prior to October 12, 1990.

  For Unit holders which become Unit owners from transfers of Units occurring
after October 11, 1990, the Revenue Reconciliation Act of 1990 repeals the
prohibition on claiming percentage depletion. A computation of percentage
depletion has been made with respect to the post October 11, 1990 transfers.
However, since cost depletion exceeds any otherwise allocable percentage
depletion, percentage depletion factors have not been presented by reference
to the number of units a Unit holder owns. Percentage depletion will continue
to be computed and compared to cost depletion on an annual basis for
applicable transfers occurring after October 11, 1990.

NONRESIDENT FOREIGN UNIT HOLDERS

  Nonresident alien individual and foreign corporation Unit holders ("Foreign
Taxpayer(s)"), in general, are subject to tax on the gross income attributable
to the Trust at a rate equal to 30 percent (or the lower rate under any
applicable treaty) without any deductions. This tax is withheld by the Trust
and remitted directly to the United States Treasury. Foreign Taxpayers who
have had tax withheld in 1996 should have received a Form 1042S from the
Trust. The Form 1042S will reflect the total Federal income tax withheld from
distributions. The amount reported on the Form 1042S should not be included as
additional income in computing taxable income, as such amount is already
included in the per Unit income items on the income and expense schedules. The
Federal income tax withheld, as reported on the Form 1042S, should be
considered as a credit by the Unit holder in computing any Federal income tax
liability.

  A Foreign Taxpayer holding income producing real property may elect to treat
the income from such real property as effectively connected with the conduct
of a United States trade or business. The income attributable to the
Properties is considered as income produced from real property. Therefore,
this election should be available to Foreign Taxpayers with respect to the
taxable income resulting from the ownership of Units. A Unit holder so
electing is entitled to claim all deductions with respect to such income, but
must file a United States income tax return to claim such deductions. This
election once made is generally irrevocable unless an applicable treaty allows
the election to be made periodically.

  The Foreign Investment in Real Property Tax Act of 1980, as amended
("FIRPTA"), generally treats interests in trusts owning United States real
property as United States real property interests. However, pursuant to
applicable Treasury regulations, Units in Trust, for purposes of FIRPTA only,
are not considered United States real property interests unless they are owned
by a Unit holder having greater than a 5% interest in the Trust. Additionally,
certain reporting provisions are applicable with respect to Foreign Taxpayers
owning a greater than 5% interest in the Trust.

  Generally, income tax is required to be withheld from any proceeds
distributed to Foreign Taxpayers at the rate of 10% of the amount realized by
Foreign Taxpayers upon the sale, exchange

(SRT 1996 TAX)

                                      A-3
<PAGE>

or other disposition of a Unit. This withholding is required only when the
FIRPTA provisions apply, as described in the preceding paragraph. In addition,
distributions, if any, that represent the Foreign Taxpayer's allocable share
of gain realized upon the sale, exchange or other disposition of a United
States real property interest by the Trust, will generally be subject to
withholding tax at a 34% rate.

  In order to avoid such withholding when the FIRPTA provisions apply, Foreign
Taxpayers will be required to furnish the applicable withholding agent with an
exemption statement certifying why such withholding is not required. Foreign
Taxpayers are encouraged to consult their own tax advisors concerning the tax
consequences of their investment in the Trust.

SALE OR EXCHANGE OF UNITS

  Generally, a Unit Holder realizes gain or loss upon the sale or exchange of
any Unit measured by the difference between the amount realized from the sale
or exchange and the adjusted tax basis of such Unit. The adjusted tax basis of
a Unit is the original basis of such Unit reduced by depletion deductions
allowable (whether deducted or not) with respect to such Unit. Trust income
allocable to such Unit to the date of sale is taxable to the selling Unit
holder. The purchaser of a Unit is taxable on Trust income allocable to such
Unit from the date of purchase forward. For Federal income tax purposes, Trust
income should generally be allocable only to the holder of record of a Unit on
each Monthly Record Date. Gain or loss on the sale of a Unit by a Unit holder
who acquired the Unit(s) prior to January 1, 1987 who is not a "dealer" with
respect to such Unit, who holds it as a capital asset and who has held it for
the required amount of time will, in general, be treated as a long-term
capital gain or loss.

  A Unit holder who is not a dealer who sells a Unit acquired on or after
January 1, 1987 must recapture the depletion deductions taken with respect to
such Unit by recognizing as ordinary income the lesser of (1) the depletion
deductions taken or (2) the amount realized upon the sale less the adjusted
basis of the Unit. Gain in excess of the recaptured depletion deduction will,
in general, be treated as a capital gain.

  Units acquired after 1987 qualifying as capital assets must be owned more
than 1 year to qualify for long-term capital gain or loss treatment.

BACKUP WITHHOLDING

  A payer is required under specified circumstances to withhold tax at the
rate of 31% on "reportable interest or dividend payments" and "other
reportable payments" (including certain oil and gas royalty payments).
Generally, this "backup withholding" is required on payments if the payee has
failed to furnish the payer a taxpayer identification number or if the payer
is notified by the Secretary of the Treasury to withhold taxes on such
payments with respect to the payee.

  Amounts withheld by payers pursuant to the backup withholding provisions are
remitted to the Internal Revenue Service and are considered a credit against
the payee's Federal income tax liability. If the payee does not incur a
Federal income tax liability for the year in which the taxes are withheld, the
payee will be required to file the appropriate income tax return to claim a
refund of the taxes withheld.

STATE INCOME TAX

  Unit holders may be required to file state income tax returns and may be
liable for state income tax as a result of their ownership of Units. The
Properties are located in Florida, Louisiana, Mississippi, New Mexico,
Oklahoma and Texas. The tax information included in this booklet is being
presented in

(SRT 1996 TAX)

                                      A-4
<PAGE>

a manner to enable Unit holders to compute the income and deductions of the
Trust attributable to each of these states. Unit holders will need this
information to comply with the state income tax filing requirements in those
states imposing a state income tax. The laws pertaining to income tax in any
given state may vary from those of another state and from those applicable to
Federal income tax. Accordingly, Unit holders are urged to consult their own
tax advisors concerning this matter.

  The Trustee has been informed that certain states have contacted Unit
holders regarding underpayments of the state income tax imposed on the Unit
holders' income from the Trust. Failure by Unit holders to properly report
their state tax liability could result in the direct withholding of state
taxes from Trust distributions. Accordingly, Unit holders are urged to
carefully review the various filing requirements of the states listed below in
order to determine if a current or prior year state income tax liability
exists as a result of the ownership of Units in the Trust.

  The state of Texas does not impose an individual income tax; therefore, no
part of the income attributable to the Trust will be subject to state income
tax in Texas for individuals. However, corporations (and Limited Liability
Companies) doing business in Texas are subject to the Texas Franchise Tax
which now includes a calculation based on the corporation's taxable income for
Federal income tax purposes. The state of Florida imposes an income tax on
resident and nonresident corporations but not individuals. Each of the other
states in which the Properties are located imposes an income tax applicable to
both resident and nonresident individuals and corporations. Generally, the
state income tax in these states is computed as a percentage of taxable income
attributable to the particular state. Furthermore, even though there are
variances from state to state, taxable income for state purposes is often
computed in a manner similar to the computation of taxable income for Federal
income tax purposes.

  All states have not adopted Federal law with respect to the percentage
method of computing depletion nor are such methods consistent among the
various states. It should be noted, however, that cost depletion is allowed by
those states indicated above which impose a state income tax. Included herein
is information to assist you in determining the respective allowable cost
depletion deductions by state.

  The following table reflects calendar year corporate and individual income
tax return due dates for the states in which the Properties are located. The
state income tax return due dates for fiscal year taxpayers will generally
allow the same period of time following the end of their respective fiscal
years as is allowed for calendar year taxpayers. However, the Texas franchise
tax return is generally due for all corporations on May 15.
