ULTRA PETROLEUM CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Expressed in U.S. dollars unless otherwise noted)

Three months ended March 31, 2002 and 2001

DESCRIPTION OF THE BUSINESS:

Ultra Petroleum Corp. (the "Corporation") is incorporated under the laws of
British Columbia, Canada. At March 1, 2000 the Corporation was continued under
the laws of the Yukon Territory, Canada. Its principal business activity is the
exploration and development of oil and gas properties located in the United
States. The Corporation also has operations in China.

1. SIGNIFICANT ACCOUNTING POLICIES:

The accompanying financial statements, other than the balance sheet data as of
December 31, 2001, are unaudited and were prepared from our records. Balance
sheet data as of December 31, 2001 was derived from our audited financial
statements, but do not include all disclosures required by U.S. generally
accepted accounting principles. Our management believes that these financial
statements include all adjustments necessary for a fair presentation of our
financial position and results of operations. All adjustments are of a normal
and recurring nature unless specifically noted. We prepared these statements on
a basis consistent with our annual audited statements and Regulation S-X.
Regulation S-X allows us to omit some of the footnote and policy disclosures
required by generally accepted accounting principles and normally included in
annual reports on Form 10-K. You should read these interim financial statements
together with the financial statements, summary of significant accounting
policies and notes to our most recent annual report on Form 10-K.

(a) Basis of presentation:

The consolidated financial statements include the accounts of the Corporation
and its wholly owned subsidiaries UP Energy Corporation, Ultra Resources, Inc
and Sino-American Energy Corporation.

All material intercompany transactions and balances have been eliminated upon
consolidation.

(b) Accounting principles:

The consolidated financial statements are prepared in accordance with accounting
principles generally accepted in Canada.

(c) Income taxes:

The Corporation uses the asset and liability method of accounting for income
taxes under which deferred tax assets and liabilities are recognized for the
future tax consequences. Accordingly, deferred tax liabilities and assets are
determined based on the temporary differences between the financial statement
and tax basis of assets and liabilities, using the enacted tax rates in effect
for the year in which differences are expected to reverse.

(d) Earnings per share:

Basic earnings per share is computed by dividing net earnings attributable to
common stock by the weighted average number of common shares outstanding during
each period. Diluted earnings per share is computed by adjusting the average
number of common shares outstanding for the dilutive effect, if any, of stock
options. The Company uses the treasury stock method to determine the dilutive
effect.

The following table provides a reconciliation of the components of basic and
diluted net income per common share for the periods ended March 31, 2002 and
2001:

                                                March 31,2002  March 31,2001

                                                                               5


(e) Foreign currency translation:

The Corporation has adopted the United States dollar as its reporting currency,
which is also its functional currency. The Corporation and its subsidiaries are
considered to be integrated operations and accounts in Canadian dollars are
translated using the temporal method. Under this method, monetary assets and
liabilities are translated at the rates of exchange in effect at the balance
sheet date; non-monetary assets at historical rates and revenue and expense
items at the average rates for the period other than depletion and depreciation
which are translated at the same rates of exchange as the related assets. The
net effect of the foreign currency translation is included in current
operations.

(f) Use of estimates:

Preparation of consolidated financial statements in accordance with generally
accepted accounting principles in Canada requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities, the
disclosure of contingent assets and liabilities at the date of the financial
statements, and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

(g) Reclassifications:

Certain amounts in the financial statements of the prior years have been
reclassified to conform to the current year financial statement presentation.

                                               =============    =============

The Corporation (through its subsidiary) participates in a long-term credit
facility with a group of banks led by Bank One N.A. The agreement specifies a
maximum loan amount of $150 million and an aggregate borrowing base of $80
million at March 1, 2002. At March 31, 2002, the Corporation had $55.5 million
outstanding and $24.5 million unused and available on the credit facility.

The credit facility matures on March 1, 2005. The note bears interest at either
the bank's prime rate plus a margin of one-half of one percent (0.50%) to one
and one quarter percent (1.25%) based on the percentage of available credit
drawn or at LIBOR plus a margin of one and one-half percent (1.5%) to two and
one-quarter (2.25%) based on the percentage of available credit drawn. An
average annual commitment fee of 0.375% is charged quarterly for any unused
portion of the credit line.

The borrowing base is subject to periodic (at least semi-annual) review and
re-determination by the bank and may be decreased or increased depending on a
number of factors including the Corporation's proved reserves and the bank's
forecast of future oil and gas prices. Additionally, the Corporation is subject
to quarterly reviews of compliance with the covenants under the bank facility
including minimum coverage ratios relating to interest, working capital, general
and administrative expenditures and advances to Sino-American Energy
Corporation. In the event of a default under the covenants, the Corporation may
not be able to access funds otherwise available under the facility. As of March
31, 2002, the Corporation was in compliance with the covenants and required
ratios.

The Corporation has secured this debt by a majority of it's proved domestic oil
and gas properties.

4. DIFFERENCES BETWEEN GENERALLY ACCEPTED ACCOUNTING PRINCIPLES IN CANADA AND
THE UNITED STATES:

The consolidated financial statements have been prepared in accordance with
generally accepted accounting principles in Canada, ("Canadian GAAP"), which may
differ in certain respects from generally accepted accounting principles in the
United States, ("US GAAP"). The Corporation currently has no significant
differences.

                                                                               6


5. RECENT ACCOUNTING PRONOUNCEMENTS:

In June 2001, the Financial Accounting Standards Board issued SFAS No. 143,
"Accounting for Asset Retirement Obligations". SFAS No. 143 requires entities to
record the fair value of liabilities for retirement obligations of acquired
assets. SFAS No. 143 is effective for fiscal years beginning after June 15,
2002. Management is currently assessing the impact, if any, of SFAS No. 143 on
the Corporation's consolidated financial statements for future periods.

ITEM 2 - MANAGEMENT DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         OF OPERATIONS

RESULTS OF OPERATIONS

QUARTER ENDED MARCH 31, 2002 VS. QUARTER ENDED MARCH 31, 2001

OPERATING REVENUES

Oil and gas revenues decreased to $9,106,379 or 46% for the quarter ended March
31, 2002 from $16,747,374 for the same period in 2001. This decrease was
attributable to a decrease in prices received for that production. During this
quarter, the Corporation's production increased to 3.8 Bcf of gas, and 34,000
barrels of condensate, up from 2.6 Bcf of gas and 28,000 barrels of condensate
for the same period in 2001. During the quarter ended March 31, 2002 the average
product prices for gas and condensate were $2.24 per Mcf and $20.58 per barrel,
respectively, compared to $6.07 per Mcf and $27.06 per barrel for the same
period in 2001.

PRODUCTION EXPENSES AND TAXES

During the quarter ended March 31, 2002 production expenses and taxes decreased
13% to $2,488,932 from $2,868,625 for the quarter ended March 31, 2001. Direct
lease operating expenses increased 108% to $486,867 for the quarter ended March
31, 2002 from $234,533 for the same period in 2001. On a per unit of production
basis, these costs increased to $.12 per Mcfe in March 2002, as compared to $.08
per Mcfe in March 2001. Production taxes for the first quarter 2002 were
$935,587, compared to $1,879,217 in first quarter 2001 or $.24 per Mcfe in first
quarter 2002, compared to $.67 per Mcfe in first quarter 2001. Production taxes
are calculated based on a percentage of revenue from production, therefore lower
realized prices contributed to the decrease. Gathering fees for the quarter
ended March 31, 2002 increased 41% to $1,066,478 from $754,875 for the same
period in 2001, attributable to higher production volumes.

DEPLETION AND DEPRECIATION

Depletion, depreciation and amortization expenses (DD&A) increased to $2,108,297
during the quarter ended March 31, 2002 from $1,610,329 for the same period in
2001. On a per unit basis, DD&A decreased to $.53 per Mcfe, from $.58 in 2001
primarily as a result of increases in the Corporation's proved reserves and
lower estimated future development costs.

GENERAL AND ADMINISTRATIVE

General and administrative expenses increased 15% to $1,219,196 during the
quarter ended March 31, 2002 from $1,058,839 for the same period in 2001. The
increase was attributable to legal, professional and compensation expenses that
coincide with the Corporation's increased activity in both Wyoming and China.

INTEREST

Interest expense for the period increased 78% to $514,061 in first quarter 2002
from $289,547 in first quarter 2001. This increase was attributable to the
increase in borrowings under the senior credit facility.

INCOME TAXES

The Corporation recorded deferred income tax expense of $1,071,387 at an
effective rate of 38.5% for the quarter ended March 31, 2002, compared to
$1,145,661 at an effective rate of 10.3% for the quarter ended March 31, 2001.
Although the Corporation is not expected to pay cash taxes in 2002, in
accordance with FAS 109 and specifically, the guidance concerning intraperiod
tax allocations, the Corporation is required to recognize tax expense evenly
throughout the year. In the prior year, income tax expense, as calculated at the
statutory rate including estimated state income tax effect, was offset by
recognition of deferred tax assets for which a valuation allowance had
previously been provided.

LIQUIDITY AND CAPITAL RESOURCES

Cash flow from operating activities was $6,084,895 for the three months ended
March 31, 2002 compared to $15,722,043 for the three months ended March 31,
2001. Operating cash flow in the three month period decreased compared to the
prior year due to decreased oil and gas prices and higher operating and other
expenses.

Cash flow used in investing activities was $16,567,267 for the three months
ended March 31, 2002 compared to $11,217,563 for the three months ended March
31, 2001. In 2002, oil and gas property and capital asset expenditures were
$16,046,135 and $521,132, respectively, compared to $11,434,824 and $95,104 in
the prior year. Amounts expended in the prior year were also offset by cash
received from the Pendaries Merger.

Net cash provided by financing activities was $13,094,693 for the three months
ended March 31, 2002 compared to net cash used of $111,374 for the three months
ended March 31, 2001. Cash received in 2002 represented borrowings of
$12,500,000 on the credit facility and proceeds from the exercise of options of
$594,693. In the prior year, net cash paid on the credit facility was $459,762,
offset by proceeds from the exercise of options of $348,388.

                                                                               7


In the three-month period ending March 31, 2002 the Corporation relied on its
existing cash flow and availability under it's credit facility to finance its
capital expenditures. The Corporation participated in continued activity from
the 2001 program on the Pinedale Anticline in Wyoming. Capital costs in China
were related to development plans for the drilling program in Bohai Bay. For the
three-month period ending March 31, 2002 capital expenditures were $10,162,685
($7,968,521 in Wyoming and $2,194,163 in Bohai Bay). At March 31, 2002, the
Corporation reported a cash position of $3,991,783 compared to $1,379,462 at
December 31, 2001. Working capital at March 31, 2002 was $(4,772,399) as
compared to $(9,327,352) at December 31, 2001.

Based on forecasted gas prices, production and bank availability, management
believes that the Corporation's continued positive cash flow from operations and
the availability under the senior credit facility will be sufficient to fund the
Corporation's budgeted capital expenditures for 2002, which are estimated to be
$50 million. However, future cash flows and continued availability of financing
are subject to a number of uncertainties beyond the Corporation's control such
as production rates, the price of gas and oil, continued favorable results of
the Corporation's drilling program and the general condition of the capital
markets for oil and gas companies. There can be no assurances that adequate
funding will be available to execute the Corporation's planned future capital
program.

CAUTIONARY STATEMENT PURSUANT TO SAFE HARBOR PROVISION OF THE PRIVATE SECURITIES
LITIGATION REFORM ACT OF 1995

This report contains "forward-looking statements" within the meaning of the
federal securities laws. These forward-looking statements, including the
Corporation's outlook for the remainder of 2002 with regard to plans for funding
operations and capital expenditures, are based on a number of risks and
uncertainties the are outside the Corporation's control. For example, future
cash flows and continued availability of financing are subject to a number of
uncertainties beyond the Corporation's control. There can be no assurances that
adequate funding will be available to execute the Corporation's planned future
capital program.

Other risks and uncertainties include, but are not limited to, fluctuations in
the price we receive for oil and gas production, reductions in the quantity of
oil and gas sold due to increased industry-wide demand and/or curtailments in
production from specific properties due to mechanical, marketing or other
problems, operating and capital expenditures that are either significantly
higher or lower than anticipated because the actual cost of identified projects
varied from original estimates and/or from the number of exploration and
development opportunities being greater or fewer than currently anticipated and
increased financing costs due to a significant increase in interest rates.

ITEM 3 - QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Corporation's revenues are derived from the sale of its crude oil and
natural gas production. The prices for oil and gas have decreased from the
prices prevailing on January 1, 2001; however, they remain extremely volatile
and sometimes experience large fluctuations as a result of relatively small
changes in supplies, weather conditions, economic conditions and government
actions. At this time the Corporation has not entered into any derivative
financial instruments to hedge oil and gas price risks for the production
volumes to which the hedge relates. However, the Corporation may enter into
hedges in the future that would reduce the Corporation's exposure on the hedged
volumes to decreases in commodity prices and limit the benefit the Corporation
might otherwise receive from any increases in commodity prices on the hedged
volumes. There have been no significant changes in market risks faced by the
Corporation since the end of 2000.
