NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation
---------------------

In the opinion of management, the accompanying unaudited financial statements
reflect all adjustments, consisting only of normal recurring adjustments, which
are necessary for a fair presentation of the consolidated financial position of
Tipperary Corporation and its subsidiaries (the "Company" or "Tipperary") at
March 31, 2001, and the results of its operations for the three-month periods
ended March 31, 2001 and 2000. The consolidated financial statements include the
accounts of Tipperary Corporation and its wholly-owned subsidiaries Tipperary
Oil and Gas Corporation and Burro Pipeline Corporation, and its 90%-owned
subsidiary, Tipperary Oil and Gas (Australia) Pty Ltd ("TOGA"), and its share of
assets, liabilities, revenues and expenses of unincorporated joint ventures and
partnerships. All intercompany transactions and balances have been eliminated.
The accounting policies followed by the Company are included in Note 1 to the
Consolidated Financial Statements in the Annual Report on Form 10-KSB, as
amended, for the transition period ended December 31, 2000. These financial
statements should be read in conjunction with the Form 10-KSB, as amended.

Impact of New Accounting Pronouncements
---------------------------------------

In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133, "Accounting for Derivative Instruments
and Hedging Activities" ("SFAS 133"). This statement, as amended by SFAS 137 and
SFAS 138, "Accounting for Certain Derivative Instruments and Certain Hedging
Activities, an amendment of SFAS 133," is effective for all fiscal quarters of
fiscal years beginning after June 15, 2000. SFAS 133 requires companies to
report the fair market value of derivatives on the balance sheet and record in
income or other comprehensive income, as appropriate, any changes in the fair
value of the derivatives. The Company's adoption of SFAS 133, effective January
1, 2001, did not have a significant impact upon the Company's financial position
or results of operations. Tipperary entered into a foreign exchange contract to
purchase Euros that were used to purchase a drilling rig from a manufacturer in
Italy on March 30, 2001

Liquidity and Operations
------------------------

With the substantial reduction in cash flow from operations following the sale
of a majority of the Company's U.S. producing oil and gas assets during fiscal
2000, there is not sufficient cash flow from operations to support Tipperary's
overhead and other ongoing cash needs over the next year. In addition, the
Company's cash on hand is not sufficient to cover anticipated capital
expenditures in excess of those to be financed by TCW Asset Management Company
("TCW"), discussed below. Tipperary's majority (54.1%) shareholder, Slough
Estates USA, Inc. ("Slough"), has indicated that it is willing to make an
additional equity investment of up to $20 million or, alternatively, that it
would be prepared to loan the Company additional funds if needed through March
2002.

NOTE 2 - RELATED PARTY TRANSACTIONS

At March 31, 2001, the Company had a corporate loan of $12,000,000 due its
largest shareholder, Slough Estates USA Inc. ("Slough"). The balance of this
loan at December 31, 2000 was $7,500,000. Tipperary increased this debt by
executing a new note for $12 million with the same terms as the $7.5 million
note, which included a maturity date of March 31, 2003. Interest is due
quarterly on the corporate loan at the 90-day London Interbank Offered Rate plus
3.5% (8.38% at March 31, 2001). Related party debt due Slough at December 31,
2000, also included a project-financing loan with a balance of $4,407,000
bearing interest at 10% per annum. In February 2001, the Company repaid the
project-financing loan using the initial proceeds of its financing with TCW
Asset Management Company ("TCW") discussed in Note 3.

On January 18, 2001, TOGA entered into a financing agreement with Slough which
provided that Slough advance payments to TOGA toward Slough's purchase of a
drilling rig and lease of the rig to TOGA. Slough has made advances under this
agreement of $2,500,000 to Tipperary, which bear interest of 10% per annum.
Under the terms of the financing agreement, payments are due to Slough monthly
for rents received from an unaffiliated drilling contractor who has entered into
an agreement with TOGA to lease the rig. Payments are also due Slough for
accrued interest on the balance of aggregate advances less rent payments.

NOTE 3 - LONG-TERM DEBT

On April 28, 2000, the Company entered into a credit agreement with TCW ("Credit
Agreement") that provides a borrowing facility of up to $17 million to be funded
on or before December 31, 2001 upon the satisfaction of certain conditions. The
obligation to repay the advances and accrued interest is evidenced by senior
secured promissory notes bearing interest at the rate of 10% per annum and
payable quarterly. Tipperary will also make monthly payments to TCW equal to a
6% overriding royalty from the gas sales revenues received by TOGA from the
Comet Ridge project. Upon payment of the loan in full, TCW has the option to
sell this overriding royalty interest to Tipperary at the net present value of
the royalty's share of future net revenues from the then proved reserves,
discounted at a rate of 15% per annum. Tipperary has the right to purchase the
interest from TCW, when both the loan has been repaid in full and TCW has
achieved a 15% internal rate of return on its investment, at the net present
value of the royalty's share of future net revenues from the then proved
reserves, discounted at a rate of 15% per annum. Principal payments are due
quarterly in an amount equal to the greater of a percentage of TOGA's operating
cash flow as defined or a scheduled minimum principal payment. The scheduled
minimum principal payment begins in March 2003 and will be equal to 5% of the
unpaid principal balance, increasing to 9% in March 2004 and 10% in March 2005.
The outstanding principal balance is due in full on March 30, 2006.

In February 2001, the Company received an initial loan advance of $7.5 million
under the Credit Agreement. Proceeds from this initial advance were used to
repay the $4,407,000 Comet Ridge project-financing loan due to Slough and pay
$1.5 million in initial costs of a 20-well drilling program on the Comet Ridge
project, with the balance provided as working capital for lender-approved
purposes. Of the $9.5 million remaining under the credit facility, about $4.8
million is available to finance the Company's share of additional costs for the
20-well drilling program and the remainder may be used for other lender-approved
drilling projects. Upon the receipt of this initial funding, the Company
recorded deferred financing costs of approximately $6.8 million for the present
value (discounted at 15%) of the overriding royalty conveyed to TCW. This cost
reduced the book value of oil and gas properties and is amortized as interest
expense over the life of the loan (61 months ending March 30, 2006). Deferred
loan costs at March 31, 2001 also include approximately $1,000,000 of other
costs incurred to obtain the TCW financing, which are likewise being amortized
to interest expense over the life of the loan.

The Company is plaintiff in a lawsuit filed on August 6, 1998, styled Tipperary
                                                                      ---------
Corporation and Tipperary Oil & Gas (Australia) Pty Ltd v. Tri-Star Petroleum
-----------------------------------------------------------------------------
Company, Cause No. CV42,265, in the District Court of Midland County, Texas
-------
involving the Comet Ridge project. By amended petition filed May 1, 2000,
Tipperary Oil & Gas Corporation joined the action as a plaintiff, along with the
already-named plaintiffs and two unaffiliated non-operating working interest
owners who previously intervened in the action as plaintiffs. James H. Butler,
Sr., and James H. Butler, Jr., owners of defendant Tri-Star Petroleum Company,
("Tri-Star") were also joined as defendants in the amended petition. The Company
and the other plaintiffs allege, among other matters, that Tri-Star and/or the
individual defendants have failed to operate the properties in a good and
workmanlike manner and have committed various other breaches of a joint
operating contract, have breached a previous mediation agreement between the
parties, have committed certain breaches of fiduciary and other duties owed to
the plaintiffs, and have committed fraud in connection with the project.
Plaintiffs also allege that Tri-Star has been removed as operator, and that
Tipperary Oil & Gas (Australia) Pty Ltd has been elected successor operator
under the operating contract. Tri-Star has answered the amended petition, and on
December 22, 2000, Tri-Star filed its first amended counterclaim alleging
tortious interference with contract, the authority to prospect covering the
project and with contractual relationships and with vendors; commercial
disparagement; foreclosure of operator's lien and alternatively forfeiture of
undeveloped acreage; unjust enrichment and declaratory relief. As of February 8,
2001, the court enjoined Tri-Star from asserting any forfeiture claims based
upon events prior to that date. Discovery is in progress and the case presently
is set for trial in December 2001.

In 1997, the Company filed a complaint along with several other plaintiffs in
BTA Oil Producers, et al. v. MDU Resources Group, Inc. in Stark County Court in
------------------------------------------------------
the Southwest Judicial District of North Dakota. The plaintiffs include major
integrated oil companies and agricultural cooperatives, as well as independent
oil and gas producers such as the Company. The plaintiffs brought the action
against the defendants for breach of gas sales contracts and processing
agreements, unjust enrichment, implied trust and related business torts. The
case concerns the sale by plaintiffs and certain predecessors of natural gas
processed at the McKenzie Gas Processing Plant in North Dakota to Koch
Hydrocarbons Company. It also concerns the contracts for resale of that gas to
MDU Resources Group, Inc. and Williston Basin Interstate Pipeline Company. After
the complaint was answered, both the plaintiffs and the defendants moved for
summary judgment on certain issues. On July 3 and October 4, 2000, and on March
2, 2001, the trial court entered two orders and a judgment deciding the issues
in the case. The plaintiffs prevailed on some issues, and the defendants
prevailed on other issues. The plaintiffs filed a Notice of Appeal on May 4,
2001.

NOTE 7 - SUBSEQUENT EVENTS

On May 4, 2001, the Company sold a 50% working interest in its 52,000-acre Lay
Creek project in Moffat County, Colorado to an unaffiliated third party and
entered into an agreement to jointly conduct exploratory drilling over this
area. The Company received $2,000,000 at closing and will be reimbursed for
$2,000,000 of its share of costs to drill and complete wells on the project
acreage. If the entire reimbursement amount has not been paid within 18 months
of the closing, the purchaser is obligated to pay the Company the remainder of
the $2,000,000 in cash. The parties are committed to drill two wells on or
before July 15, 2001, subject to extensions that may be obtained due to rig
availability or regulatory delays, and three additional wells by June 17, 2002.
Under the full cost method of accounting, no gain or loss will be recognized on
the sale of this interest.

NOTE 8 - RESTATEMENT

As disclosed in the Company's Form 10-QSB for the quarterly period ended March
31, 2000, the Company's oil and gas properties in its U.S. full cost pool were
held for sale in connection with the Company's redirection of focus toward
increasing reserves and production of natural gas from coalbed methane
properties. The Company had suspended the depreciation, depletion and
amortization of these properties for the quarterly periods in fiscal 2000 during
which these properties were held for sale. The Company subsequently revised its
previously reported quarterly results of operation to include depreciation,
depletion and amortization of these oil and gas properties through the date of
disposal. The above revision, which increased depreciation, depletion and
amortization for the quarterly period ended March 31, 2000 by $451,000, had no
effect on the Company's full year's results of operations for fiscal 2000, nor
did the revision have any impact on cash flows for any period. The following
table shows the effect of this restatement for the three months ended March 31,
2000 (in thousands except per share amounts).

what may be expressed or forecasted in such forward-looking statements.
Furthermore, the Company undertakes no obligation to update, amend or clarify
forward-looking statements, whether as a result of new information, future
events or otherwise. Readers are encouraged to read the SEC reports of the
Company, particularly its Form 10-KSB, as amended, for the transition period
ended December 31, 2000, for meaningful cautionary language disclosing why
actual results may vary materially from those anticipated by management.

Overview

The Company is principally engaged in the exploration for and development and
production of natural gas. The Company is primarily focused on coalbed methane
properties, with its major producing property located in Queensland, Australia.
Tipperary also holds exploration permits in Queensland and is involved in
coalbed methane exploration in the United States through projects in the Hanna
Basin of Wyoming and in western Colorado. The Company seeks to increase its
coalbed methane gas reserves through exploration and development projects and
possibly through the acquisition of producing properties.

The Company's exploration and development efforts, and the majority of its
capital investment in recent years, have been focused on the Comet Ridge coalbed
methane project in Queensland, Australia. The Company's 90%-owned Australian
subsidiary, Tipperary Oil & Gas (Australia) Pty Ltd ("TOGA"), owns a 62.25% non-
operating undivided interest in the project, which consists of Authority to
Prospect ("ATP") 526 covering approximately 1,088,000 acres in the Bowen Basin.
In addition to the interest in the Comet Ridge property, TOGA holds a 100%
interest in other exploration permits granted to TOGA by the Queensland
government. These permits cover a total of approximately 1.5 million acres
comprising ATPs 655, 675 and 690, which have initial terms expiring on October
31, 2003, February 29, 2004 and November 30, 2004, respectively.

Financial Condition, Liquidity and Capital Resources

The Company's primary sources of liquidity during the past few years have been
from debt and equity financing and sales of producing properties. Tipperary has
used these funds to pay off outstanding bank debt and for exploration and
development operations including the acquisition of additional interests in the
Comet Ridge project. Remaining funds were invested in domestic properties, most
notably in the Hanna Basin coalbed methane project, in which the Company owns a
non-operated 49% working interest, and in undeveloped oil and gas leasehold
interests in Colorado.

With the substantial reduction in cash flow from operations following the sale
of a majority of the Company's U.S. producing oil and gas assets during fiscal
2000, there is not sufficient cash flow from operations to support Tipperary's
overhead and other ongoing cash needs over the next year. In addition, the
Company's cash on hand is not sufficient to cover anticipated capital
expenditures in excess of those to be financed through its credit agreement with
TCW Asset Management Company ("TCW"), discussed below. The Company is evaluating
various transactions that would enable it to meet the aforementioned cash
funding needs, including additional debt financing, sales of common stock and
asset sales. On April 17, 2001, the Company filed a registration statement with
the U.S. Securities and Exchange Commission to register shares under a rights
offering in order to raise up to $30,000,000. The offering price and number of
shares have not yet been determined. Tipperary's majority (54.1%) shareholder,
Slough Estates USA, Inc. ("Slough"), has indicated that it is willing to make an
additional equity investment of up to $20 million through this rights offering
or, alternatively, that it would be prepared to loan the Company additional
funds if needed through March 2002.

The Company had unrestricted cash and temporary investments of $1,680,000 as of
March 31, 2001, compared to $1,579,000 as of December 31, 2000. The restricted
cash as of March 31, 2001 includes cash in collateral accounts

                                       8
<PAGE>

maintained in connection with TCW financing, the use of which is restricted to
disbursements made either to TCW or as otherwise approved by TCW. At March 31,
2001, the Company had working capital of $5,985,000 compared to working capital
of $2,256,000 as of December 31, 2000. During the three months ended March 31,
2001, cash flows were provided by debt financing. These proceeds were used to
fund capital expenditures and operating activities.

Net cash used by operating activities was $1,705,000 during the three months of
2001 compared to cash provided of $664,000 during the corresponding prior year
period. The decrease in net cash from operations was attributable to the sale of
most of the Company's U.S. oil and gas properties during fiscal 2000.

During the three months ended March 31, 2001, the Company had net receipts of
$7,998,000 from financing, which included borrowings of $7,500,000 from TCW and
$4,500,000 from Slough. Capital expenditures of $6,192,000 included $2,076,000
for the purchase of a drilling rig to be leased to a drilling contractor in
Queensland, Australia (discussed below), $1,718,000 for acreage acquisitions in
Colorado, $1,293,000 for drilling, completion and other costs on the Comet Ridge
project and $932,000 for drilling and completion costs in the Hanna Basin of
Wyoming.

For the prior year's quarter ended March 31, 2000, the Company invested
approximately $4,000,000 in property plant and equipment, which was primarily
for the acquisition of additional interests in the Comet Ridge project. Net cash
provided by financing activities was $1,525,000 and included $2,400,000 received
from the sale of stock and issuance of warrants in connection with financing
arrangements with two individual investors. These equity proceeds were used to
partially fund the aforementioned acquisition. During the prior year's quarter,
the Company also made principal repayments of $868,000 on the Comet Ridge
project-financing loan then outstanding from Slough.

At December 31, 2000, the Company owed Slough $11,906,000, consisting of a
corporate loan of $7,500,000 and a project-financing loan of $4,407,000, which
was used to finance the Company's share of an eight-well drilling program on the
Comet Ridge project during fiscal 1999 and fiscal 2000. The Company repaid the
project-financing loan in February 2001, using the initial proceeds of a
financing agreement with TCW discussed below. Since December 31, 2000, the
Company has borrowed an additional $4.5 million under the corporate loan
agreement with Slough, increasing the total amount owed to Slough to $12 million
as of March 31, 2001. The promissory note for $12 million matures March 31, 2003
and bears interest at the 90-day London Interbank Offered Rate plus 3.5%. The
interest rate was 8.38% at March 31, 2001.

In February 2001, the Company received an initial loan advance of $7.5 million
under a $17 million borrowing facility with TCW. Proceeds from this initial
advance were used to repay Slough for the Comet Ridge project-financing loan of
$4,407,000, pay $1.5 million in initial costs of a 20-well drilling program on
the Comet Ridge project and pay approximately $240,000 of expenses related to
the financing. The balance of $1,353,000 is to be used as working capital for
lender-approved purposes. Of the $9.5 million remaining under the credit
facility, about $4.8 million is available to finance the Company's share of
additional costs for the 20-well drilling program and the remainder may be used
for other lender-approved drilling projects. Upon the receipt of this initial
funding, the Company recorded deferred financing costs of $6.8 million for the
present value (discounted at 15%) of the overriding royalty conveyed to TCW.
This cost reduced the book value of oil and gas properties and is amortized as
interest expense over the life of the loan. Deferred loan costs at March 31,
2001 also include approximately $1,000,000 of costs incurred to obtain the TCW
financing, which are likewise being amortized to interest expense over the life
of the loan.

Tipperary proposed the 20-well drilling program to the other owners in July 2000
and estimated the cost at approximately $10 million. The Company subsequently
received Authorities for Expenditure ("AFEs") from the operator with estimated
costs of $15 million. If the operator is unable to complete the project below
the AFE costs, Tipperary's share of the $5 million difference, or almost $3.1
million, will have to be funded from other sources, as Tipperary does not have
internal sources of capital at this time to cover increased drilling and
completion costs. With the approval of TCW, approximately $1 million of working
capital available from their initial funding could be used to cover a portion of
any excess capital costs.

The obligation to repay the TCW advances and accrued interest is evidenced by
senior secured promissory notes bearing interest at the rate of 10% per annum
and payable quarterly. Tipperary will also make monthly payments to TCW equal to
a 6% overriding royalty from the gas sales revenues received by TOGA from the
Comet Ridge project. Upon payment of the loan in full, TCW has the option to
sell this overriding royalty interest to Tipperary at the net present value of
the royalty's share of future net revenues from the then proved reserves,
discounted at a rate of 15% per annum.

                                       9
<PAGE>

Tipperary has the right to purchase the interest from TCW, when both the loan
has been repaid in full and TCW has achieved a 15% internal rate of return on
its investment, at the net present value of the royalty's share of future net
revenues from the then proved reserves, discounted at a rate of 15% per annum.
Principal payments on the TCW financing will be due quarterly in an amount equal
to the greater of a percentage of TOGA's operating cash flow as defined, or a
scheduled minimum principal payment. The scheduled minimum principal payment
begins March 2003 and will be equal to 5% of the unpaid principal balance,
increasing to 9% in March 2004 and 10% in March 2005. The outstanding principal
balance is due in full on March 30, 2006.

TOGA has entered into an Agreement for Hire ("Lease Agreement") with an
unaffiliated drilling contractor in Queensland, Australia ("Lessee") to lease
from TOGA the drilling rig and related equipment. The terms of the Lease
Agreement provide that the Lessee will use the rig to drill on TOGA's ATPs and
possibly on ATP 526. To the extent the rig is not being used for TOGA's drilling
activities, it may, with TOGA's consent, be used by the Lessee to drill wells
for others. The lease payments are structured to be due and payable with the
drilling of each well on which the rig is used. No interest or finance charge
accrues on the lease, but the Company will benefit from reduced costs to drill
wells on ATP 526 or TOGA's ATPs. In the case of drilling on the Comet Ridge
project, the Company's co-owners will also benefit from their proportionate
share of the cost reduction. The lessee also received a two-year option to buy
the rig and related equipment at TOGA's net cost.

During January 2001, Slough advanced $2,500,000 to Tipperary for Slough's
purchase of the rig from TOGA. The advances were made pursuant to a financing
agreement between Slough and the Company dated January 18, 2001, providing that
Slough would purchase the rig from TOGA and enter into a lease agreement to
lease the rig to TOGA. The parties are considering restructuring the transaction
as a loan rather than as advances toward the purchase of the rig. See Note 2 to
the Consolidated Financial Statements.

Results of Operations - Comparison of the Three Months Ended March 31, 2001 and
2000

As described in Note 8 to the Consolidated Financial Statements, the Company's
oil and gas properties in its U.S. full cost pool were held for sale. The
Company subsequently revised its previously reported quarterly results of
operation to include depreciation, depletion and amortization of these oil and
gas properties in its U.S. full cost pool through their date of disposal. The
revision had no effect on the Company's full year's results of operations for
fiscal 2000, nor did it have any impact on cash flows for any period.

The Company incurred a net loss of $1,195,000 for the three months ended March
31, 2001, compared to a net loss of $311,000 for the three months ended March
31, 2000. This decrease is attributable to reduced revenues due to the sale of
most of the Company's producing properties in the U.S. during 2000. The table
below provides a comparison of operations for the three months ended March 31,
2001 with those of the prior year's quarter.

The sale of domestic producing properties significantly reduced worldwide oil
and gas volumes. This volume reduction caused significant decreases in worldwide
operating revenue, operating expense and net income. The Company's overall
average gas price decreased due to an unfavorable exchange rate adversely
affecting the price received for Australia sales. The average lifting cost per
Mcfe decreased 34% worldwide due to an increase in gas production volumes from
the Company's Australian operations.

An increase in general and administrative expense of 13% is primarily due to the
absence of overhead reimbursements on operated properties sold during 2000. The
67% decrease in DD&A costs and 38% decrease in DD&A rate per Mcfe is
attributable to the sale of domestic producing properties. Increased production
and reserve volumes in Australia also contributed to worldwide DD&A and rate
reductions and reduced the Australian DD&A rate per Mcf by 32%.

Interest expense for the three months ended March 31, 2001 increased by $129,000
due to the amortization of deferred financing cost and decreased by $64,000 for
interest capitalization. The remaining $65,000 decrease was attributable to a
lower average debt balance and lower interest rates during the current quarter
as compared to the prior year's quarter. Both deferred financing cost
amortization and interest capitalization are non-cash items and were not
included in interest expense for the three months ended March 31, 2000.
