                 SPINDLETOP OIL & GAS CO. AND SUBSIDIARIES
                NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                (Unaudited)

1. BASIS OF PRESENTATION AND ORGANIZATION

The accompanying financial statements are presented in accordance with the
requirements of Form 10-Q and consequently do not include all of the
disclosures normally required by generally accepted accounting principles or
those normally made in the Company's annual Form 10-K filing.  Accordingly,
the reader of this Form 10-Q may wish to refer to the Company's Form 10-K for
the year ended December 31, 2010 for further information.

The consolidated financial statements presented herein include the accounts of
Spindletop Oil & Gas Co., a Texas corporation ("the Company") and its wholly
owned subsidiaries, Prairie Pipeline Co., a Texas corporation and Spindletop
Drilling Company, a Texas corporation.  All significant inter-company
transactions and accounts have been eliminated.

In the opinion of management, the accompanying unaudited interim financial
statements contain all material adjustments, consisting only of normal
recurring adjustments necessary to present fairly the financial condition, the
results of operations and changes in cash flows of the Company and its
consolidated subsidiaries for the interim periods presented.  Although the
Company believes that the disclosures are adequate to make the information
presented not misleading, certain information and footnote disclosures,
including a description of significant accounting policies normally included in
financial statements prepared in accordance with generally accepted accounting
principles generally accepted in the United States of America, have been
condensed or omitted pursuant to such rules and regulations.


Subsequent Events:
------------------

The Company has evaluated subsequent events through the issuance date of this
report of May 16, 2011.


Item 2. - Management's Discussion and Analysis of Financial Condition and
          Results of Operations

WARNING CONCERNING FORWARD LOOKING STATEMENTS
---------------------------------------------

The following discussion should be read in conjunction with the financial
statements and notes thereto appearing elsewhere in this report.

This Report on Form 10-Q may contain forward-looking statements within the
meaning of the federal securities laws, principally, but not only, under the
caption "Management's Discussion and Analysis of Financial Condition and
Results of Operations. "  We caution investors that any forward-looking
statements in this report, or which management may make orally or in writing
from time to time, are based on management's beliefs and on assumptions made

                                   - 8 -

by, and information currently available to, management.  When used, the words
"anticipate", "believe", "expect", "intend", "may", "might", "plan",
"estimate", "project", "should", "will", "result" and similar expressions which
do not relate solely to historical matters are intended to identify forward-
looking statements.  These statements are subject to risks, uncertainties, and
assumptions and are not guarantees of future performance, which may be affected
by known and unknown risks, trends, uncertainties, and factors, that are beyond
our control.  Should one or more of these risks or uncertainties materialize,
or should underlying assumptions prove incorrect, actual results may vary
materially from those anticipated, estimated, or projected.  We caution you
that while forward-looking statements reflect our good faith beliefs when we
make them, they are not guarantees of future performance and are impacted by
actual events when they occur after we make such statements.  We expressly
disclaim any responsibility to update our forward-looking statements, whether
as a result of new information, future events or otherwise.  Accordingly,
investors should use caution in relying on past forward-looking statements,
which are based on results and trends at the time they are made, to anticipate
future results or trends.

Some of the risks and uncertainties that may cause our actual results,
performance or achievements to differ materially from those expressed or
implied by forward-looking statements include, among others, the factors listed
and described at Item 1A "Risk Factors" in the Company's Annual Report on Form
10-K, which investors should review.  There have been no changes from the risk
factors previously described in the Company's Form 10-K for the fiscal year
ended December 31, 2010 (the "Form 10-K").

The current global economic and financial crisis could lead to an extended
national or global economic recession. A slowdown in economic activity caused
by a recession would likely reduce national and worldwide demand for oil and
natural gas and result in lower commodity prices for long periods of time.
Prices for oil and natural gas are volatile.   Costs of exploration,
development and production have not yet adjusted to current economic
conditions.  Prolonged, substantial decreases in oil and natural gas prices
would likely have a material adverse effect on the Company's business,
financial condition and results of operations, could further limit the
Company's access to liquidity and credit and could hinder its ability to
satisfy its capital requirements.

Capital and credit markets experienced unprecedented volatility and disruption
over the last few years and continue to be unpredictable. Given the current
levels of market volatility and disruption, the availability of funds from
those markets has diminished substantially. Further, arising from concerns
about the stability of financial markets generally and the solvency of
borrowers specifically, the cost of accessing the credit markets has increased
as many lenders have raised interest rates, enacted tighter lending standards
or altogether ceased to provide funding to borrowers.

Due to these capital and credit market conditions, Spindletop cannot be certain
that funding will be available to the Company in amounts or on terms acceptable
to the Company. The Company is evaluating whether current cash balances and
cash flow from operations alone would be sufficient to provide working capital
to fully fund the Company's operations. Accordingly, the Company is evaluating
alternatives, such as joint ventures with third parties, or sales of interest

                                   - 9 -

in one or more of its properties. Such transactions if undertaken could result
in a reduction in the Company's operating interests or require the Company to
relinquish the right to operate the property. There can be no assurance that
any such transactions can be completed or that such transactions will satisfy
the Company's operating capital requirements. If the Company is not successful
in obtaining sufficient funding or completing an alternative transaction on a
timely basis on terms acceptable to the Company, Spindletop would be required
to curtail its expenditures or restructure its operations, and the Company
would be unable to continue its exploration, drilling, and recompletion
program, any of which would have a material adverse effect on Spindletop's
business, financial condition and results of operations.

The Obama administration has recently set forth budget proposals which if
passed, would significantly curtail our ability to attract investors and raise
capital.  Proposed changes in the Federal income tax laws which would eliminate
or reduce the percentage depletion deduction and the deduction for intangible
drilling and development costs for small independent producers, will
significantly reduce the investment capital available to those in the industry
as well as our Company.  Lengthening the time to expense seismic costs will
also have an adverse effect on our ability to explore and find new reserves.

Other sections of this report may also include suggested factors that could
adversely affect our business and financial performance.  Moreover, we operate
in a very competitive and rapidly changing environment.  New risks may emerge
from time to time and it is not possible for management to predict all such
matters; nor can we assess the impact of all such matters on our business or
the extent to which any factor, or combination of factors, may cause actual
results to differ materially from those contained in any forward-looking
statements.  Given these uncertainties, investors should not place undue
reliance on forward-looking statements as a prediction of actual results.
Investors should also refer to our quarterly reports on Form 10-Q for future
periods and current reports on Form 8-K as we file them with the SEC, and to
other materials we may furnish to the public from time to time through
Forms 8-K or otherwise.


Results of Operations

2011 Compared to 2010
---------------------

Oil and gas revenues for the first quarter of 2011 were $2,196,000, as compared
to $1,677,000 for the same period in 2010, an increase of approximately
$519,000 or 31.0%.  Of this increase, approximately $462,000 was due to a one
time payment of suspended oil revenues due on the acquisition of a 25% working
interest in the Davis Heirs well#1 for several years from 2002 to 2011 (See
Item 5 below).

Natural gas revenues for the first three months of 2011 were $826,000 compared
to $1,156,000 for the same period in 2010, a decrease of $330,000, or 28.6%.
Natural gas sales volumes for the first quarter of 2011 were approximately
164,000 MCF compared to approximately 201,000 MCF during the first quarter of
2010, a decrease of approximately 37,000 mcf or 18.4%.


                                   - 10 -

Average natural gas prices received were $4.98 per MCF in the first quarter of
2011 as compared to $5.76 per MCF in the first quarter of 2010, a decrease of
approximately $0.78 per MCF or 13.5%.

Oil sales for the first three months of 2011 were approximately $1,370,000
compared to approximately $521,000 in the first quarter of 2010, an increase of
approximately $849,000 or 163.0%.  Of this increase, approximately $462,000 was
due from a one time payment of suspended oil revenues for several years from
2002 to 2011 from the working interest acquired in the Davis Heirs #1 well.
Oil sales volumes for the first quarter of 2011 were approximately 19,600 BBLS,
8,865 BBLS of which were from the acquisition of the working interest in the
Davis Heirs #1 well and suspended oil volume from 2002 to 2011 of this well,
compared to approximately 11,500 BBLS during the first quarter of 2010, an
increase of approximately 8,100 BBLS, or 70.4%.  Excluding the Davis well, the
oil volumes for the first quarter of 2011 were 10,735 BBLS, or a decrease of
6.7%.

Average oil prices received were $84.39 per BBL in the first quarter of 2011
compared to $71.35 per BBL in the first three months of 2010, an increase of
approximately $13.04 per BBL or 18.3%.  The average oil prices calculated above
did not include the working interest in the Davis Heirs #1 well which was
calculated separately at an average blended price from 2002 to 2011 of $52.13
per BBL.

Real estate income was approximately $113,000 during the first quarter of 2011
compared to $125,000 for the first three months of 2010, a decrease of
approximately $12,000, or 9.6%.  This decrease is due to a net loss of rentable
square footage from tenants who have moved out.  The Company has replaced many
of these leases during the first quarter of 2011.

Interest income was $17,000 during the first quarter of 2011 as compared to
$39,000 during the same period in 2010, a decrease of approximately $22,000 or
56.4%.  This was due to a drop in interest rates between years.  The interest
rate on certain deposit accounts at one of the banks in which the Company is a
depositor was decreased significantly toward the end of 2010 resulting in an
approximate $18,000 reduction in interest income received for the year in 2010.
This decreased interest rate has affected the first quarter comparison of both
years.

Other income for the first three months of 2011 was $180,000 as compared to
$19,000 for the same time period in 2010, an increase of $161,000.
Approximately $155,000 of this increase is due to money received for Farmout
Agreements in the first quarter of 2011.

Lease operations expense in the first quarter of 2011 was $492,000 as compared
to $249,000 in the first quarter of 2010, a net increase of approximately
$243,000, or 97.6%.  Of this increase, approximately $80,000 was from the
acquisition of the working interest in the Davis Heirs #1 well. Approximately
$94,000 of the increase was for expenses incurred on six operated New Mexico
wells acquired in December of 2010.  Approximately $23,000 was for expenses
associated with other wells acquired subsequent to the first quarter of 2010,
and approximately $30,000 from increased workover expenses between the periods.



                                   - 11 -

Production taxes, gathering and marketing expenses in the first quarter of 2011
were approximately $206,000 as compared to $180,000 for the first quarter of
2010, an increase of approximately $26,000.  Of this amount, approximately
$21,000 was due to the acquisition of the working interest in the Davis Heirs
#1well.

Real estate operations expense in the first quarter of 2011 was approximately
$49,000 compared to $52,000 during the same period in 2010, a decrease of
approximately $3,000.

Depreciation, depletion, and amortization expense for the first quarter of 2011
was $244,000 as compared to $229,000 for the first quarter of 2010, an increase
of $15,000, or 6.6%.  $214,000 of the amount for the first quarter of 2011 was
for amortization of the full cost pot of capitalized costs as compared with
$199,000 for the first quarter of 2010.  The Company re-evaluated its proved
oil and gas reserve quantities as of December 31, 2010.  This re-evaluated
reserve base was adjusted for first quarter 2011 additions and dispositions of
reserves, and reduced for oil and gas reserves that were produced during the
quarter.  A depletion rate of 1.784% for the quarter was calculated and applied
to the Company's full cost pot of capitalized oil and gas properties.

Asset Retirement Obligation ("ARO") expense for the first three months of 2011
was approximately $12,000 as compared to approximately $22,000 for the same
time period in 2010; a decrease of $10,000.

General and administrative costs for the first quarter of 2011 were
approximately $750,000 as compared to approximately $764,000 for the first
quarter of 2010, a decrease of $14,000 or 1.8%.

Interest expense was approximately $15,000 for the first quarter of 2011
compared to approximately $17,000 for the same period in 2010, a decrease of
approximately $2,000.  This is due to the continued reduction of the principal
amount of the loan on the office building owned by the Company as interest on
the note is calculated and paid based on the unpaid balance of the loan.

Financial Condition and Liquidity

The Company's operating capital needs, as well as its capital spending program
are generally funded from cash flow generated by operations.  Because future
cash flow is subject to a number of variables, such as the level of production
and the sales price of oil and natural gas, the Company can provide no
assurance that its operations will provide cash sufficient to maintain current
levels of capital spending.  Accordingly, the Company may be required to seek
additional financing from third parties in order to fund its exploration and
development programs.

Item 4. - Controls and Procedures

(a) As of the end of the period covered by this report, Spindletop Oil & Gas
Co. carried out an evaluation, under the supervision and with the participation
of the Company's management, including the Company's Principal Executive
Officer and Principal Financial and Accounting Officer, of the effectiveness of
the design and operation of the Company's disclosure controls and procedures
pursuant to Exchange Act Rule 13a-15 and 15d-15.  Based upon the evaluation,

                                   - 12 -

the Company's Principal Executive Officer and Principal Financial and
Accounting Officer concluded that the Company's disclosure controls and
procedures were effective as of the end of the period covered by the report.

(b) There have been no changes in the Company's internal controls over
financial reporting during the quarter ended March 31, 2011 that have
materially affected, or are reasonably likely to materially affect the
Company's internal controls over financial reporting.


Part II - Other Information

Item 5. - Other Information

                                East Texas

During the first quarter of 2011, the Company completed the acquisition of a
25% working interest in the Davis Heirs #1 well in Leon County, Texas.  By
virtue of this acquisition, the Company obtained 25% of the revenues from this
interest net of drilling costs, completion costs, and operating expenses from
the date of first production in December, 2002.  As a result of this
acquisition, the Company has booked a one time payment of $462,111 as gross
oil revenue from the production and sale of oil for the years 2002 to 2011 at
an average price of $52.13 per barrel (8,865 bbls).  In addition, the Company
recorded $185,308 as drilling and development costs, $28,453 as lease and well
equipment, $21,331 as severance taxes, and $80,246 as lease operating expenses.
As of the first of the year, the Davis Heirs #1 well is producing approximately
6 bopd from the Halliday Woodbine field.

                                West Texas:

Effective April 1, 2011, the Company acquired a 100% working interest and 75%
net revenue interest in the University #21-34 well in Winkler, County, Texas.
The well was producing approximately 8 mcfgpd from the Morrow Formation at a
perforated interval of 15,511-531' as of the effective date.

                                New Mexico:

Effective April 1, 2011, the Company acquired a 10.5% working interest and
8.1375% net revenue interest in the Foster #1 well, in Lea County, New Mexico.
The well was producing at a rate of 50 mcfgpd, 0.5 bopd and 8 bswpd from the
San Andres Formation at a perforated interval of 4,510-22' as of the effective
date.

                                Mississippi

Effective April 1, 2011, the Company acquired a non-operated 9.56% working
interest and 8.34409% net revenue interest in the Mary Hall #7-10 well in
Jefferson Davis County, Mississippi.  The well was producing approximately
125 mcfgpd and 2 bswpd from the Whitesand Hosston field as of the effective
date.




                                   - 13 -

For all of the above wells, the Company cautions that the initial production
rates of a newly completed well or newly recompleted well or the production
rates at the effective date of acquisition may not be an indicator of
stabilized production rates or an indicator of the ultimate recoveries
obtained.
