                            TEXAS PACIFIC LAND TRUST
                          NOTES TO FINANCIAL STATEMENTS
                               SEPTEMBER 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 September 30, 2001 and the results of
         its operations for the three and nine months ended September 30, 2001
         and 2000 and its cash flows for the nine months ended September 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 nine months ended September
         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 nine months ended September
         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.

                           Management's Discussion and
                       Analysis of Financial Condition and
                          Results of Operations for the
                           Nine and Three Months Ended
                           September 30, 2001 and 2000


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

Earnings per sub-share certificate for the third quarter of 2001 were $1.62
compared to $.39 in the third quarter of 2000. Total revenues were $7,889,591
compared to $1,898,689, an increase of 315%.

In the third quarter of 2001, land sales totaled $5,882,678 which was 2,975.92
acres at an average price of $1,977 per acre. In the comparable period of 2000,
1,551.43 acres were sold for $162,210, an average of $105 per acre.

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 were $1,809,596 for the third quarter of
2001 compared to $1,517,098 for the third quarter of 2000, an increase of 19.3%.

Oil and gas royalty revenue was $1,057,493 compared to $1,083,586 for the third
quarter of 2000, down 2.4%. Oil royalty revenue was $674,501, down 5.0% from the
third quarter of 2000. Oil royalty production subject to the Trust's royalty
interest was up 6.1% in the third quarter of 2001, while the average price per
royalty barrel of crude oil was down 10.5%. Gas royalty revenue for the third
quarter was $382,992, up 2.6% on a volume decrease of 3.5% and price increase of
6.4%.

Easement and sundry income was $630,716 for the third quarter of 2001, up 105%
from the third quarter of 2000. These categories of income are not predictable
and commonly have large swings in any given period.

Interest revenue was down 10.1% for the third quarter of 2001 compared to the
third quarter of 2000. Interest from notes receivable was $172,647, down 12.7%
for the 2001 period due to a decrease in average note receivable balances for
the period. Notes receivable for land sold were $11,653,696 as of September 30,
2001, an increase of 36.9% from the end of the third quarter of 2000. Sundry
interest was $24,670 for the third quarter of 2001, which was up 13.7% from the
third quarter of 2000.

Taxes, other than Federal income taxes, were down 4.7% for the third quarter of
2001 compared to the third quarter of 2000.

General and administrative expenses were down 24.9% over the third quarter of
2000. This is mainly due to a decrease in professional fees and administrative
expenses.

$5,982,333, an average of $1,446 per acre, compared to 18,165.96 acres for

Easement and sundry income was $954,881 for the first nine months of 2001, up

year.

Interest revenue was down 5.9% for the first nine months of 2001 compared to the
first nine months of 2000. Interest from notes receivable was $549,285, down
6.3% for the 2001 period and sundry interest was $63,706, down 2.0%.

Taxes, other than Federal income taxes were up 6.8% for the first nine months of
2001 from the first nine months of 2000.

General and administrative expenses were down 2.4% for the first nine months of
2001 over the comparable 2000 period.

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.
