                            TEXAS PACIFIC LAND TRUST
                          NOTES TO FINANCIAL STATEMENTS
                                  JUNE 30, 2001



(1)      In the opinion of management, the accompanying unaudited financial
         statements contain all adjustments (consisting of only normal recurring
         accruals) necessary to present fairly the financial position of Texas
         Pacific Land Trust (Trust) as of June 30, 2001 and the results of its
         operations for the three and six months ended June 30, 2001 and 2000
         and its cash flows for the six months ended June 30, 2001 and 2000,
         respectively. These financial statements and footnotes included herein
         should be read in conjunction with the Trust's annual financial
         statements as of December 31, 2000 and 1999 and for each of the years
         in the three year period ended December 31, 2000 included in the
         Trust's Form 10-K.

(2)      No value is assigned to the land, unless acquired through foreclosure;
         consequently, no allowance for depletion is computed, and no charge to
         income is made therefore, and no cost is deducted from the proceeds of
         the land sales in computing gain or loss thereon.

(3)      The Sub-shares and the Certificates of Proprietary Interest are freely
         interchangeable in the ratio of one Certificate of Proprietary Interest
         for 600 Sub-shares or 600 Sub-shares for one Certificate of Proprietary
         Interest.

(4)      The Trust's effective Federal income tax rate is less than the 34%
         statutory rate because taxable income is reduced by statutory
         percentage depletion allowed on mineral royalty income.

(5)      The results of operations for the three and six months ended June 30,
         2001 are not necessarily indicative of the results to be expected for
         the full year.

(6)      Cash in excess of daily requirements is invested in money market
         instruments with maturities of ninety days or less. Such investments
         are deemed to be cash equivalents for purposes of the statements of
         cash flows.

         Supplemental cash flow information for the six months ended June 30,
         2001 and 2000 is summarized as follows:

(7)      The Trust has adopted SFAS No. 131, Disclosures about Segments of an
         Enterprise and Related Information which establishes standards for the
         way public business enterprises are to report information about
         operating segments. SFAS No. 131 utilizes the management approach as a
         basis for identifying reportable segments. The management approach is
         based on the way that management organizes the segments within the
         enterprise for making operating decisions and assessing performance.
         The Trust's management views its operations as one segment and believes
         the only significant activity is managing the land which was conveyed
         to the Trust in 1888. Trust management makes decisions about resource
         allocation and performance assessment based on the same financial
         information presented in these financial statements. Managing the land
         includes sales and leases of such land, and the retention of oil and
         gas royalties.

(8)      In July 2001 the Trust entered into a contract to sell approximately
         560 acres in El Paso county for approximately $5,600,000. The contract
         is subject to certain contingencies that allows purchaser to cancel
         until September 10, 2001, but all contracts should close in the third
         quarter. The Trust's basis in the real estate to be sold is
         approximately $1,450,000.00.

                       Analysis of Financial Condition and
                          Results of Operations for the
                                Six Months Ended
                             June 30, 2001 and 2000
                       -----------------------------------


Results of Operations for Quarter Ended June 30, 2001 Compared to Quarter Ended
June 30, 2000

Earnings per sub-share were $.41 for the second quarter of 2001 compared to $.32
in the second quarter of 2000. Total revenues were $1,908,926 compared to
$1,571,735, an increase of 21.5%.

Land sales for the second quarter of 2001 were 1,159 acres at an average price
of approximately $70 per acre for a total of $81,115. This compares to 960 acres
at an average price of approximately $125 per acre for a total of $120,001 in
the second quarter of 2000. In looking forward the Trust has made land sale
contracts thus far in the third quarter for $5,900,000. One contract totaling
$5,600,000 in El Paso county is subject to certain contingencies that allows
purchaser to cancel until September 10, 2001, but all contracts should close in
the third quarter.

Land sales may vary widely from year to year and quarter to quarter. The total
dollar amount, the average price per acre, and the number of acres sold in any
one year or quarter should not be assumed to be indicative of land sales in the
future. The Trust is a passive seller of land; it does not actively solicit
sales of land. The demand for and the sales price of any particular tract of the
Trust's land is influenced by many factors including the national and local
economies, the rate of residential and commercial development in nearby areas,
livestock carrying capacity, and the conditions of the local agricultural
industry which itself is influenced by range conditions and prices for livestock
and other agricultural products. Approximately 99% of the Trust's land is
classified as ranch land and intermingled with other ownerships to form ranching
units. Ranch land sales are, therefore, largely dependent on the actions of the
adjoining landowners.

Rentals, royalties and sundry income amounted to $1,625,758 for the second
quarter of 2001 compared to $1,234,552 for the second quarter of 2000, up 31.7%.

Oil and gas royalty revenue was $1,250,190 for the second quarter of 2001, up
36.2% compared to the second quarter of 2000. Oil royalty revenue was $745,129,
up 21.5% for the 2001 period. Crude oil production subject to the Trust's
royalty interest was up 25.2% in the second quarter of 2001. The average price
of crude oil was decreased 3.0%. Gas royalty revenue was $505,061 in the second
quarter of 2001, up 65.6% on a volume decrease of 6.7% and a price increase of
77.2%.

Easement and other sundry income was $185,148 for the second quarter of 2001, up
42.7% from the second quarter of 2000. This income is unpredictable and may vary
greatly from quarter to quarter.

Interest revenue was down 7.0% in the second quarter of 2001 compared to the
same period of 2000. Interest from notes receivable amounted to $184,552, a 7.0%
decrease from the 2000 period. Notes receivable for land sold were $7,438,696 as
of June 30, 2001, down 13.9% from June 30, 2000, due to payments received from
note makers. Sundry interest was $17,501 for the second quarter of 2001, down
5.8% from the second quarter of 2000. Sundry interest income fluctuates based on
cash on hand for investment, and interest rates on short term investments.

Taxes, other than Federal income taxes, were up 4.6% due to an increase in
royalty income production taxes in the second quarter of 2001 compared to the
second quarter of 2000.

General and administrative expenses were up 12.8% for the second quarter of 2001
compared with the same period of 2000.

Management's Discussion (cont'd)

Results of Operations for Six Months Ended June 30, 2001 Compared to Six Months
Ended June 30, 2000

Earnings per sub-share for the first six months of 2001 were $.72 compared to
$.59 in the first six months of 2000. Total revenues were $3,556,655 compared to
$3,646,260, a decrease of 2.5%. The main reason for earnings per sub-share being
up 22.0% and revenues being down 2.5% is due to land sold in 2000 with a basis
of $588,815 which shows as an expense against earnings.

Land sales for the first six months of 2001 were 1,160.85 acres at an average
price of approximately $86 per acre for a total of $99,655. This compares to
16,614.53 acres at an average price of approximately $54 per acre for a total of
$902,727 in the first six months of 2000.

Rentals, royalties, and sundry income amounted to $3,041,326 for the first six
months of 2001 compared to $2,311,639 for the first six months of 2000, up
31.6%.

Oil and gas royalty revenue for the first six months of 2001 was $2,438,907, up
37.1% compared to the first six months of 2000. Oil royalty revenue was
$1,403,389, up 15.9% for the 2001 period. Crude oil production was up 10.8% in
the first six months of 2001, and the average price per barrel was up 4.7%. Gas
royalty revenue was $1,035,518 in the first six months of 2001, up 82.1% on a
volume decrease of 6.5%, and a price increase of 94.6%.

Easement and other sundry income was $324,165 in the first six months of 2001,
up 24.8% from the first six months of 2000. This was mainly due to increase of
pipeline easement and seismic permit income which are unpredictable and vary
greatly from one period to another.

Interest revenue was $415,674 for the first six months of 2001, down 3.8% from
the 2000 period. Interest from notes receivable was $376,638, down 3.1% from the
2000 period. Sundry interest was $39,036 for the first six months, down 9.8%
from the 2000 period.

Taxes, other than Federal income taxes in the first six months of 2001 were up
12.9%. This is due to the increase in royalty income taxes.

General and administrative expenses for the first six months of 2001 were up
9.5% from the first six months of 2000.

Liquidity and Capital Resources

The Trust's oil and gas royalty revenues, lease rentals and receipts of interest
and principal on notes receivable have generated more than adequate amounts of
cash to meet the Trust's needs and should continue to do so in the predictable
future.
