PRESIDENT'S LETTER
================================================================================

To the Co-owners of Helmerich & Payne, Inc.

Sometimes risk factors are difficult to identify, much less quantify.
Unthinkable risks confronted each of us and our families in the aftermath of the
terrorist attacks on the World Trade Center and Pentagon. Dinner table
conversations at home and discussions at work contemplated possible threats of
anthrax exposure, bioterror, and even nuclear "dirty bomb" strikes on civilians.

Today we are a nation at war, facing a real and present danger to our basic
freedoms and liberty. We are also a nation united and determined. A renewed
patriotic spirit has raised a standard against the evil that struck at our core
values. We have witnessed acts of untold heroism and sacrifice, along with a
flood of prayers and support from friends of freedom around the globe.

We have been inspired by the leadership of President Bush: "The course of this
conflict is not known, yet its outcome is certain. Freedom and fear, justice and
cruelty have always been at war and we know that God is not neutral between
them. The advance of human freedom now depends on us. We will rally the world to
this cause by our efforts, by our courage. We will not tire, we will not falter,
and we will not fail."


2



The President has urged all Americans to take up the fight, in part, by leading
our lives. That is what your Company intends to do. Each of our employees plays
a proud part in an industry vital to our country's energy security.

Remarkably, energy prices are falling at the end of 2001, even in the face of
the current geopolitical situation in the Middle East. Will a "smoking gun"
surface to further implicate Iraq in terrorist sponsorship? Will a bloody and
volatile Palestinian-Israeli conflict deteriorate further?

How should markets price the possible risk of a far-reaching supply disruption?

We're confident the market will sort it all out. That time-tested dynamic of
free markets is one of the many enduring principles worth fighting for and
defending. All the while, your Company will stand prepared and financially fit
for the challenges and opportunities ahead.

                                               Sincerely,

                                               /s/ HANS HELMERICH

                                               Hans Helmerich

                                                                               3

DRILLING  HELMERICH & PAYNE INTERNATIONAL DRILLING CO.
================================================================================

SUMMARY  Both oil and natural gas prices increased substantially at the
beginning of the year, resulting in higher demand for land rigs in the United
States. Industry census data produced by Reed-Hycalog indicates that 93 percent
of all U.S. land rigs were active during 2001, a level of activity not achieved
since the early 1980s. The resulting impact of this environment on the Company's
2001 financial performance was significant. Contract drilling revenues increased
39 percent, and earnings before interest, taxes, depreciation, and amortization
(EBITDA) increased by over 50 percent, driven primarily by increased activity in
the U.S. land market.

At the close of fiscal 2001, Helmerich & Payne International Drilling Co. owned
ten offshore platform rigs located in the Gulf of Mexico, and 81 land rigs
located in the United States (49), Venezuela (14), Ecuador (7), Bolivia (6),
Colombia (3), and Argentina (2). The Company also had five international land
rigs undergoing major upgrades in the U.S., as well as five land rigs and two
offshore platform rigs at various stages of new construction at year-end.

Additionally, the Company operates four management contracts on customer-owned
platform rigs, three offshore California and one offshore Equatorial Guinea,
West Africa.

UNITED STATES OPERATIONS  Rig utilization averaged 97 and 98 percent,
respectively, for land and offshore platform rigs during the year. The Company
worked an average of 41 land rigs and ten offshore platform rigs for the whole
year, up from 32 land and nine offshore platform rigs in 2000. A total of 11
rigs were added to the land fleet in 2001, seven new FlexRigs(TM), one
reconditioned medium depth rig, and three deep rigs that were transferred from
international operations.

The Company plans to complete the construction of 20 FlexRigs during 2002, which
will be available for work in the U.S. or international markets. The highly
mobile FlexRig, named for its flexible drilling range of 8,000 to 18,000 feet,
offers significant drilling efficiencies through improved technology, including
disc-brakes, block control system, and the Company's patented round mud tank
system. The FlexRig design has reduced the average moving time by more than
one-half of that for a conventional 1500 horsepower rig. The FlexRig design
includes many health, safety, and environmental (HSE) improvements and features
reducing HSE hazards. These include noise abatement, enhanced anti-fall
protection, and an integrated fluid containment system around the rig floor.

During 2001, the Company received commitments to build and operate two new
self-moving platform rigs in the Gulf of Mexico, one each from Shell Exploration
& Production Co. and BP. These rigs are scheduled to commence operations in the
third quarter of 2002.

(TM) FlexRig is a trademark of Helmerich & Payne International Drilling Co.


                                                                               5


INTERNATIONAL OPERATIONS  Rig utilization averaged 56 percent in 2001, compared
with 47 percent in 2000, primarily because the Company moved eight rigs to the
U.S. for drilling opportunities or refurbishment during 2001. Revenues increased
13 percent over last year, but EBITDA decreased slightly as improvements in
Venezuela, Equatorial Guinea, Ecuador, and Argentina were offset by declines in
Colombia and Bolivia. Increased operating profit was primarily the result of
reduced depreciation expense caused by rig transfers from international to
domestic operations, as well as a change in the estimated useful life of
drilling equipment, increasing it from ten to 15 years.

OUTLOOK  The Company has lowered its expectations for drilling activity in the
coming year because of the precipitous drop in both oil and natural gas prices
caused by reduced economic activity and mild weather in the U.S. Because the
present downturn does not appear to be due to excessive supplies, the Company
anticipates that it will be short-lived, improving as energy demand rises in
response to U.S. and world economic recovery. This is the second volatile
drilling cycle in four years and, with each downturn, the industry loses
experienced employees and momentum on capital projects, many of which require
long lead times to bring to fruition. The inevitable upturn in the cycle is
likely to become even more pronounced, stretching the already thin human,
technological, and financial resources of the industry. The Company has focused
its investment efforts on delivering the latest in equipment and technology to
the field and in training our people to operate safely and effectively. Our
primary goal remains to deliver high quality equipment and services that will
add measurable value to a customer's drilling operation.

EXPLORATION & PRODUCTION  HELMERICH & PAYNE, INC.
================================================================================

SUMMARY  Helmerich & Payne, Inc. explores for and produces oil and natural gas
primarily in Kansas, Louisiana, Oklahoma, and Texas. The Company also provides
natural gas marketing services through its wholly owned subsidiary, Helmerich &
Payne Energy Services, Inc. A substantial increase in the price of natural gas
produced record financial results for the Exploration and Production segment in
2001. Revenues and operating profit grew 38 percent and 44 percent,
respectively, over 2000 levels. Helmerich & Payne Energy Services, Inc.'s
revenues increased 24 percent in 2001, although operating profit remained flat
for the year. Oil production declined seven percent to average 2,242 barrels per
day in 2001, while prices remained flat at $27.88 per barrel compared with
$27.95 per barrel in 2000. Natural gas production also declined to 116,128
thousand cubic feet (Mcf) per day, compared with 128,204 Mcf per day in 2000.
Natural gas prices increased 63 percent to average $4.55 per Mcf in 2001,
compared with $2.79 per Mcf in 2000.

EXPLORATION RESULTS  Even though the Company had a record financial performance,
it was a disappointing year for the exploration effort. Proved reserves declined
from 300 billion cubic feet equivalent (Bcfe) to 252 Bcfe during 2001. Almost
half of this decline was the result of the lower natural gas price used in the
reserve calculation, which was $1.90 per Mcf in 2001, compared with $5.13 per
Mcf in 2000.

The Company participated in 123 (69.5 net) wells in 2001, 29 (17 net) of which
were dry holes. Given the high natural gas prices, additional emphasis was
placed on developing proved undeveloped reserves during the year. Forty-seven
gross wells were drilled for this purpose in 2001. The remaining wells included
40 (19 net) wildcat wells, five of which exposed the Company to over 250 Bcfe in
net potential reserve additions.

OUTLOOK  Given that oil and gas prices have declined substantially, the Company
plans to be highly selective with regard to drilling prospects in 2002, and will
reduce capital expenditures by as much as half of what they were in 2001. With
the assistance of the investment bank of Petrie Parkman & Co., the Company is
continuing to explore strategic alternatives for the Oil and Gas Division. These
alternatives include combining the Company's oil and gas operations with another
of similar size to form a separate, stand-alone exploration and production
company. The Company engaged in discussions with a number of companies during
the past year and plans to continue these efforts into 2002.

MANAGEMENT'S DISCUSSION & ANALYSIS OF
RESULTS OF OPERATIONS AND FINANCIAL CONDITION
================================================================================
HELMERICH & PAYNE, INC.

RISK FACTORS AND FORWARD-LOOKING STATEMENTS

The following discussion should be read in conjunction with the consolidated
financial statements and related notes included elsewhere herein. The Company's
future operating results may be affected by various trends and factors, which
are beyond the Company's control. These include, among other factors,
fluctuations in oil and natural gas prices, expiration or termination of
drilling contracts, currency exchange gains and losses, changes in general
economic conditions, rapid or unexpected changes in technologies, risks of
foreign operations, uninsured risks, and uncertain business conditions that
affect the Company's businesses. Accordingly, past results and trends should not
be used by investors to anticipate future results or trends.

With the exception of historical information, the matters discussed in
Management's Discussion & Analysis of Results of Operations and Financial
Condition include forward-looking statements. These forward-looking statements
are based on various assumptions. The Company cautions that, while it believes
such assumptions to be reasonable and makes them in good faith, assumed facts
almost always vary from actual results. The differences between assumed facts
and actual results can be material. The Company is including this cautionary
statement to take advantage of the "safe harbor" provisions of the Private
Securities Litigation Reform Act of 1995 for any forward-looking statements made
by, or on behalf of, the Company. The factors identified in this cautionary
statement are important factors (but not necessarily all important factors) that
could cause actual results to differ materially from those expressed in any
forward-looking statement made by, or on behalf of, the Company.

RESULTS OF OPERATIONS

All per share amounts included in the Results of Operations discussion are
stated on a diluted basis. Helmerich & Payne, Inc.'s net income for 2001 was
$144,254,000 ($2.84 per share), compared with net income of $82,300,000 ($1.64
per share) in 2000, and $42,788,000 ($0.86 per share) in 1999. Included in the
Company's net income, but not related to its operations, were after-tax gains
from the sale of investment securities of $691,000 ($0.01 per share) in 2001,
$8,152,000 ($0.16 per share) in 2000, and $1,562,000 ($0.03 per share) in 1999.
In addition to income from security sales, the Company also recorded net income
during 2000 of $6,637,000 ($0.13 per share) from gains relating to non-monetary
dividends received. Also included in net income is the Company's portion of
income from its


10



equity affiliates, which totaled $0.04 per share in 2001, $0.06 in 2000, and
$0.07 in 1999. The Company's equity affiliates are Atwood Oceanics, Inc. and a
50-50 joint venture with Atwood called Atwood Oceanics West Tuna Pty. Ltd.,
which owns an offshore platform rig.

Consolidated revenues were $826,854,000 in 2001, $631,095,000 in 2000, and
$564,319,000 in 1999. The 31 percent increase from 2000 to 2001 was due to
significant increases in revenues from all of the operating divisions. Revenues
from investments decreased by $21,381,000. Contract Drilling Division revenues
increased by 39 percent due to the strengthening of the U.S. land rig market.
This resulted in higher utilization of the Company's rigs and higher dayrates.
Oil and Gas Division revenues rose 33 percent over 2000 due primarily to higher
oil and natural gas prices. The 12 percent increase in consolidated revenues
from 1999 to 2000 was primarily due to higher oil and natural gas prices
resulting in an increase of $87,278,000 in Oil and Gas Division revenues and
increased investment revenues of $24,216,000. Partially offsetting these
increases was a reduction of international contract drilling revenues of
$46,438,000.

Revenues from investments were $10,592,000 in 2001, $31,973,000 in 2000, and
$7,757,000 in 1999. Included in revenues were pre-tax gains from the sale of
investment securities of $1,189,000 in 2001, $13,295,000 in 2000, and $2,547,000
in 1999. Interest income from short-term investments increased in 2001 and 2000
because the Company's cash and cash equivalent balances increased in each of
these years. Dividend income decreased in 2001, primarily because in 2000, the
Company recognized $10,706,000 of non-monetary dividends when three Company
investees spun-off subsidiaries to their shareholders.

Costs and expenses in 2001 were $591,752,000, 72 percent of revenues, compared
with 78 percent in 2000, and 88 percent in 1999. Operating costs, as a
percentage of operating revenues, were 51 percent in 2001, 53 percent in 2000,
and 60 percent in 1999. Operating costs, as a percentage of operating revenues,
declined each of the last two years, primarily due to proportionately higher
revenues.

Effective October 1, 2000, the Company changed the estimated useful life of its
drilling equipment from ten years to 15 years, resulting in lower annual
depreciation expense of approximately $30 million in 2001. Excluding write-downs
of producing properties, depreciation expense was $78,400,000 in 2001,
$106,815,000 in 2000, and $99,108,000 in 1999. Producing property


                                                                              11


write-downs totaled $8,909,000 in 2001, $4,036,000 in 2000, and $10,059,000 in
1999.

General and administrative expenses increased by 33 percent from 2000 to 2001,
to a total of $15,415,000, compared with $11,578,000 in 2000, and $14,198,000 in
1999. Expenses rose this past year due to costs associated with legal,
accounting, and investment banking fees related to the potential spin-off of the
Oil and Gas Division, settlements of lawsuits, higher pension expense accrual,
and higher labor and bonus charges, compared with 2000. General and
administrative expenses decreased in 2000, compared to 1999, due to the
inclusion in 1999 of reduced allocations of charges to operations and unusually
high expenses relating to corporate aircraft maintenance. Income taxes, as a
percentage of pre-tax income, were 40 percent in 2001, 42 percent in 2000, and
40 percent in 1999.

Interest expense for the Company was negative $32,000 in 2001, $3,076,000 in
2000, and $6,481,000 in 1999. Most of the expense reduction from 2000 to 2001
resulted from a reversal of interest expense previously accrued relating to an
ad valorem tax dispute that was settled for less interest costs than accrued.
The specific case was settled during 2001, resulting in a reversal of interest
expense of $2,280,000 that had been accrued in 1999. Additionally, the Company
reduced its overall debt position during the last half of 1999 and early 2000,
resulting in less debt related interest expense booked in the last three years.

CONTRACT DRILLING DIVISION revenues, which include both domestic and
international segment revenues, increased 39 percent to $487,289,000 during
2001, from $351,080,000 in 2000. Revenues for 2000 were 11 percent lower than in
1999. Division operating profit of $136,166,000 was almost triple that of the
$45,461,000 recorded in 2000. Operating profit for 2000 was 24 percent lower
than in 1999.

Domestic segment revenues were $332,399,000 in 2001, $214,531,000 in 2000, and
$213,647,000 in 1999. Domestic segment operating profit was $107,691,000 in
2001, $35,808,000 in 2000, and $30,154,000 in 1999. Rig utilization for the U.S.
land fleet was 97 percent in 2001, 85 percent in 2000, and 69 percent in 1999.
Domestic platform rig utilization was 98 percent in 2001, 94 percent in 2000,
and 95 percent in 1999.

Both U.S. land rig and U.S. platform rig revenues increased in 2001 over 2000.
Dayrates for U.S. land rigs and total operating days for the U.S. land rig
segment increased dramatically during 2001. Operating profit for the


12


domestic operation improved dramatically from 2000 to 2001, mostly on the
strength of average land rig dayrates, which improved more than 50 percent, and
the resulting improvement in profit margins. The previously discussed change in
the estimated useful life of drilling equipment increased domestic operating
profit by approximately $15 million in 2001. U.S. platform rig dayrates did not
improve, but total operating days helped boost revenues for the year.
Improvements in revenues and operating profit from 1999 to 2000 were primarily
the result of average U.S. land rig dayrates and profit margins moving up, while
the platform business improved only slightly. During 1999, there were
approximately $40 million of revenues recorded as a result of a rig construction
project that was completed in early 2000.

International segment revenues increased by 13 percent from 2000 to 2001, after
falling by 25 percent from 1999 to 2000. International operating profit rose to
$28,475,000 in 2001, from $9,753,000 in 2000. Operating profit for 1999 was
$29,845,000. International rig utilization averaged 56 percent during 2001, 47
percent in 2000, and 53 percent in 1999. International operating profit improved
during 2001, mainly due to lower depreciation expenses resulting from a change
in the estimated useful life of the Company's drilling equipment, as previously
discussed. The impact of the change added approximately $15 million to
international operating profit in 2001. Revenues in Venezuela increased 24
percent during 2001, and the Company expects to see activity improve slightly in
2002. The Company's labor contract in Equatorial Guinea added $6,054,000 to
international revenues in 2001. The decline in operating profit from 1999 to
2000 was primarily due to reduced activity in Colombia where the Company had
previously employed ten rigs. Activity in Colombia continued to decline in 2000
and 2001, and currently, the Company has one rig working out of the three
remaining in that country. Conversely, Ecuador's rig count has grown from three
in 1999 to seven in 2001, and an eighth, newly refurbished rig will be shipped
during the second quarter of 2002, to begin work under a one-year contract.

The Company has international operations in several South American countries.
With the exception of Venezuela, the Company believes that its exposure to
currency valuation losses is minimal due to the fact that virtually all billings
and payments are in U.S. dollars. In Venezuela, approximately 50 percent of the
Company's billings are in U.S. dollars and 50 percent are in bolivars, the local
currency. As a result, the Company is exposed to risks of currency devaluation
in Venezuela because of the bolivar denominated receivables. During 2001, the
Company experienced a loss of $796,000 due to devaluation of the bolivar,


                                                                              13


compared with a $687,000 loss in 2000, and a $712,000 loss in 1999. The Company
anticipates additional devaluation losses in Venezuela during 2002, but is
unable to predict the extent of either the devaluation or its financial impact.
Should Venezuela experience a 25 to 50 percent devaluation, Company losses could
range from approximately $1,600,000 to $2,600,000.

OIL AND GAS DIVISION operating results include those from its Exploration and
Production segment, as depicted in the following table. The Natural Gas
Marketing segment will be discussed separately.

</Table>

Exploration and Production segment revenues and operating profit increased
significantly this year as average prices received for the Company's natural gas
production rose dramatically. Average prices received for natural gas increased
by 63 percent, while average crude oil prices remained flat, compared to 2000.
Natural gas and crude oil production for the Company decreased by nine percent
and seven percent, respectively. Increased exploration drilling resulted in dry
hole and abandonment charges rising to $33.5 million in 2001, compared with
$22.6 million in 2000, and $11.4 million in 1999. Revenues and operating profit
for 2000 were up substantially from 1999 due to significant increases in both
commodity price levels and Company production volumes for natural gas and crude
oil. Average prices for natural gas increased by 52 percent and average crude
oil prices increased by 91 percent from 1999 to 2000. In 2000, natural gas and
crude oil production increased by six percent and 35 percent, respectively, over
1999 levels. Producing property impairment write-downs totaled $8,909,000 in
2001, $4,036,000 in 2000, and $10,059,000 in 1999.

During 2002, the Company's Oil and Gas Division intends to decrease its capital
spending over the previous year. However, dry hole, abandonment, and geophysical
expenses are difficult to predict and will continue to impact operating profit
for the coming year. Additionally, with a reduced capital spending budget, it is
expected that the Company's production volumes for natural gas and crude oil
will decline during the year.

The Company has retained the investment banking firm of Petrie Parkman & Co. to
analyze, develop, and facilitate possible strategic options for the Oil and Gas
Division. It is uncertain whether such a transaction will occur or, if so, when.

The Company's Natural Gas Marketing segment, Helmerich & Payne Energy Services,
Inc., (HPESI) derives most of its revenues from selling natural gas produced by
other unaffiliated companies. Total Natural Gas Marketing segment revenues were
$100,111,000 in 2001, $80,907,000 in 2000, and $55,259,000 in 1999. Operating
profit was $5,254,000 in 2001, $5,271,000 in 2000, and $4,418,000 in 1999. The
operating profit margin declined to 5.2 percent in 2001, from 6.5 percent in
2000, and 8 percent in 1999. A rapid decline in natural gas prices over the last
three-quarters of the year as well as an increasingly competitive gas marketing
environment was primarily responsible for lower margins in 2001. Most of the
natural gas owned and produced by the Exploration and Production segment is sold
through HPESI to third parties at variable prices based on industry pricing
publications or exchange quotations. Revenues for the Company's own natural gas
production are reported by the Exploration and Production segment with the
Natural Gas Marketing segment retaining a market-based fee from the sale of such
production. HPESI sells most of its natural gas with monthly or daily contracts
tied to industry market indices, such as Inside FERC Gas Market Report. The
Company, through HPESI, has natural gas delivery commitments for periods of less
than a year for approximately 59 percent of its total natural gas production. At
times, the Exploration and Production segment may direct HPESI to enter into
fixed price natural gas sales contracts on its behalf for a small portion
(normally less than 20 percent) of its natural gas sales for periods of less
than 12 months to guarantee a certain price. In 2001, HPESI had approximately
three percent of its natural gas sales portfolio dedicated to such fixed price
sales contracts compared to 13.6 percent in 2000. As of September 30, 2001,
HPESI had no long-term fixed contracts.

REAL ESTATE DIVISION revenues totaled $11,018,000 for 2001, $8,999,000 for 2000,
and $8,671,000 for 1999. Operating profit was $6,315,000 in 2001, $5,346,000 in
2000, and $5,338,000 in 1999. The increase in revenues and operating profit in
2001 was due to the sale of a small parcel of raw land. Occupancy rates,
revenues, and operating profit remained solid in 2001 due to the continued
strength of the Tulsa economy. No material changes are anticipated in the Real
Estate Division in 2002.

The Company adopted Statement of Financial Accounting Standards (SFAS) No. 133,
"Accounting for Derivative Instruments and Hedging Activities," effective
October 1, 2000, which required that all derivatives be recognized


                                                                              15


as assets or liabilities in the balance sheet and that these instruments be
measured at fair value. The effect of SFAS No. 133 on the Company's results of
operations and financial position was not material for fiscal year 2001, and is
not expected to be material in 2002.

In 2001, the Financial Standards Board (FASB) issued SFAS No. 143, "Accounting
for Asset Retirement Obligations," and SFAS No. 144, "Accounting for the
Impairment or Disposal of Long-lived Assets." The Company does not anticipate
that these pronouncements will have an immediate material impact on its results
of operations or financial position. More information on these pronouncements
can be found in Note 12 on page 30 of this Annual Report.

LIQUIDITY AND CAPITAL RESOURCES

The Company's capital spending was $274,670,000 in 2001, $131,932,000 in 2000,
and $122,951,000 in 1999. Net cash provided from operating activities for those
same time periods were $278,856,000 in 2001, $201,836,000 in 2000, and
$158,694,000 in 1999. In addition to the net cash provided by operating
activities, the Company also generated net proceeds from the sale of portfolio
securities of $24,439,000 in 2001, $12,569,000 in 2000, and $2,803,000 in 1999.

During 2000, the Company announced a program (FlexRig II program) under which it
would construct 12 new FlexRigs at an approximate cost of between $7.5 and $8.25
million each. During 2001, the Company completed construction on seven of those
12 rigs. Additionally, the Company announced in 2001 that it would embark on
another construction project (FlexRig III program) to build an additional 25
FlexRigs at an approximate cost of $10.2 million each. It is expected that the
Company will complete construction on 15 of those 25 rigs under the FlexRig III
program during 2002. During 2001, the Company also announced that it had reached
agreement with two operators for offshore platform rig operations in the Gulf of
Mexico. This will result in the Company spending approximately $50 million to
construct two offshore platform rigs that should commence operations in the
Company's third quarter of 2002.

These projects, along with ongoing remodification and refurbishment of existing
equipment, plus additional drill pipe and other expenditures, should bring
Contract Drilling capital expenditures to approximately $340 million in 2002.
Additionally, the Oil and Gas Division has estimated its capital spending needs
for the coming year to be approximately $50 million. These capital expenditures,
along with miscellaneous real estate and corporate


16


capital expenditures, should bring total Company capital spending for 2002 close
to $400 million. Funding for this significant increase in Company capital
expenditures will come from existing cash balances, internally generated cash
flow, additional bank borrowings, and proceeds from securities sales.

As described in Note 2 of Notes to Consolidated Financial Statements, in October
1998, the Company obtained $50 million in long-term debt proceeds. The $50
million of long-term debt matures in October 2003. The interest rate on this
debt fluctuates based on the 30-day London Interbank Offered Rate (LIBOR).
However, simultaneous to receiving the $50 million in long-term debt proceeds,
the Company entered into a $50 million interest rate swap agreement with a major
national bank. The swap effectively fixes the interest rate on this facility at
5.38 percent for the entire five-year term of the note. The Company's interest
rate risk exposure is limited to its potential short-term borrowings, and
results predominately from fluctuations in short-term interest rates as measured
by 30-day LIBOR. This exposure should increase during 2002, as the Company
secures additional debt financing.

The strength of the Company's balance sheet is substantial, with current ratios
for 2001 and 2000 at 2.7 and 3.4, respectively, and with total bank borrowings
less than four percent of total assets at September 30, 2001. Additionally, the
Company manages a large portfolio of marketable securities that, at the close of
2001, had a market value of $226,134,000, with a cost basis of $119,165,000. The
portfolio, heavily weighted in energy stocks, is subject to fluctuation in the
market and may vary considerably over time. Excluding the Company's
equity-method investments, the portfolio is marked to market on the Company's
balance sheet for each reporting period. During 2001, the Company paid a
dividend of $0.30 per share, or a total of $15,047,000, representing the 30th
consecutive year of dividend increases.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
================================================================================
HELMERICH & PAYNE, INC.                        September 30, 2001, 2000 and 1999

- --------------------------------------------------------------------------------
NOTE 1  SUMMARY OF ACCOUNTING POLICIES
- --------------------------------------------------------------------------------

CONSOLIDATION -

The consolidated financial statements include the accounts of Helmerich & Payne,
Inc. (the Company), and all of its wholly-owned subsidiaries. Fiscal years of
the Company's foreign consolidated operations end on August 31 to facilitate
reporting of consolidated results.

TRANSLATION OF FOREIGN CURRENCIES -

The Company has determined that the functional currency for its foreign
subsidiaries is the U.S. dollar. The foreign currency transaction loss for 2001,
2000, and 1999 was $494,000, $664,000, and $21,000, respectively.

USE OF ESTIMATES -

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the amounts reported in the consolidated financial statements and
accompanying notes. Actual results could differ from those estimates.

PROPERTY, PLANT AND EQUIPMENT -

The Company follows the successful efforts method of accounting for oil and gas
properties. Under this method, the Company capitalizes all costs to acquire
mineral interests in oil and gas properties, to drill and equip exploratory
wells which find proved reserves and to drill and equip development wells.
Geological and geophysical costs, delay rentals and costs to drill exploratory
wells which do not find proved reserves are expensed. Capitalized costs of
producing oil and gas properties are depreciated and depleted by the
unit-of-production method based on proved oil and gas reserves as determined by
the Company and its independent engineers. Reserves are recorded for capitalized
costs of undeveloped leases based on management's estimate of recoverability.
Costs of surrendered leases are charged to the reserve.

In accordance with Statement of Financial Accounting Standards (SFAS) No. 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to
be Disposed Of," the Company recognizes impairment losses for long-lived assets
used in operations when indicators of impairment are present and the
undiscounted cash flows are not sufficient to recover the carrying amount of the
asset. The Company recognized impairment charges of approximately $8.9 million,
$4.0 million and $10.1 million in 2001, 2000, and 1999, respectively, for proved
Exploration and Production properties which are included in depreciation,
depletion, and amortization expense. After-tax, the impairment charge reduced
2001, 2000, and 1999 net income by approximately $5.5 million, $2.5 million, and
$6.2 million, respectively. On a diluted basis the impairment charges reduced
earnings per share in 2001, 2000, and 1999 by $0.11, $0.05, and $0.13,
respectively. The Company evaluates impairment of exploration and production
assets on a field by field basis. Fair value on all long-lived assets is based
on discounted future cash flows or information provided by sales and purchases
of similar assets.

Substantially all property, plant and equipment other than oil and gas
properties is depreciated using the straight-line method based on the following
estimated useful lives:

Contract drilling equipment......................   4-15
Real estate buildings and equipment..............  10-50
Other............................................   3-33
</Table>

As a result of an economic evaluation of useful lives of its drilling equipment,
the Company extended the depreciable life of its rig equipment from ten to 15
years. This change will provide a better matching of revenues and depreciation
expense over the useful life of the equipment. This change, effective October 1,
2000, reduced depreciation expense for 2001 by approximately $30 million.

CASH AND CASH EQUIVALENTS -

Cash and cash equivalents consist of cash in banks and investments readily
convertible into cash which mature within three months from the date of
purchase.

INVENTORIES -

Inventories, primarily materials and supplies, are valued at the lower of cost
(moving average or actual) or market.

SHIPPING COSTS -

The Company's shipping and handling costs are included under operating costs for
all periods presented.

DRILLING REVENUES -

Contract drilling revenues are comprised primarily of daywork drilling contracts
for which the related revenues and expenses are recognized as work progresses.
Fiscal 2000 and 1999 contract drilling revenues also include revenues of
$4,109,000, and $40,790,000, respectively, from a rig construction contract for
which revenues were recognized based on the percentage-of-completion method,
measured by the percentage that incurred costs to date bear to total estimated
costs. The Company does not currently have any third party rig construction
contracts.

GAS IMBALANCES -

The Company recognizes revenues from gas wells on the sales method, and a
liability is recorded for permanent imbalances resulting from gas wells in which
the Company has sold more production than it is entitled.

INVESTMENTS -

The cost of securities used in determining realized gains and losses is based on
the average cost basis of the security sold. Net income in 2001 includes a loss
of approximately $1.4 million, $0.03 per share on a diluted basis, resulting
from the Company's assessment that the decline in market value of certain
available-for-sale securities below their financial cost basis was other than
temporary. Net income in 2000 included approximately $6.6 million, $0.13 per
share on a diluted basis, on gains related to non-monetary transactions within
the Company's available-for-sale security invested portfolio which were
accounted for at fair value.

Investments in companies owned from 20 to 50 percent are accounted for using the
equity method with the Company recognizing its proportionate share of the income
or loss of each investee. The Company owned approximately 22% of Atwood
Oceanics, Inc. (Atwood) at both September 30, 2001 and 2000. The quoted market
value of the Company's investment was $78,000,000 and $125,063,000 at September
30, 2001 and 2000, respectively. Retained earnings at September 30, 2001
includes approximately $25,514,000 of undistributed earnings of Atwood.

INCOME TAXES -

Deferred income taxes are computed using the liability method and are provided
on all temporary differences between the financial basis and the tax basis of
the Company's assets and liabilities.

OTHER POST EMPLOYMENT BENEFITS -

The Company sponsors a health care plan that provides post retirement medical
benefits to retired employees. Employees who retire after November 1, 1992 and
elect to participate in the plan pay the entire estimated cost of such benefits.

The Company has accrued a liability for estimated workers compensation claims
incurred. The liability for other benefits to former or inactive employees after
employment but before retirement is not material.

EARNINGS PER SHARE -

Basic earnings per share is based on the weighted-average number of common
shares outstanding during the period. Diluted earnings per share includes the
dilutive effect of stock options and restricted stock.

EMPLOYEE STOCK-BASED AWARDS -

Employee stock-based awards are accounted for under Accounting Principles Board
Opinion No. 25, "Accounting for Stock Issued to Employees" and related
information. Fixed plan common stock options do not result in compensation
expense, because the exercise price of the stock equals the market price of the
underlying stock on the date of grant.

TREASURY STOCK -

Treasury stock purchases are accounted for under the cost method whereby the
entire cost of the acquired stock is recorded as treasury stock. Gains and
losses on the subsequent reissuance of shares are credited or charged to
additional paid-in-capital using the average-cost method.

CAPITALIZATION OF INTEREST -

The Company capitalizes interest on major projects during construction. Interest
is capitalized on borrowed funds, with the rate based on the average interest
rate on related debt. Capitalized interest for 2001, 2000, and 1999 was $1.3
million, $0.4 million, and $0.1 million, respectively.

INTEREST RATE RISK MANAGEMENT -

The Company uses derivatives as part of an overall operating strategy to
moderate certain financial market risks and is exposed to interest rate risk
from long-term debt. To manage this risk, in October 1998, the Company entered
into an interest rate swap to exchange floating rate for fixed rate interest
payments through October 2003, the remaining life of the debt. The difference to
be paid or received is accrued and recognized as an adjustment of interest
expense. As of September 30, 2001, the Company's interest rate swap had a
notional principal amount of $50 million.

The Company's accounting policy for these instruments is based on its
designation of such instruments as hedging transactions. An instrument is
designated as a hedge based in part on its effectiveness in risk reduction and
one-to-one matching of derivative instruments to underlying transactions. The
Company records all derivatives on the balance sheet at fair value.

For derivative instruments that are designated and qualify as a cash flow hedge
(i.e., hedging the exposure of variability in expected future cash flows that is
attributable to a particular risk), the effective portion of the gain or loss on
the derivative instrument is reported as a component of other comprehensive
income in stockholders' equity and reclassified into earnings in the same period
or periods during which the hedged transaction affects earnings. The change in
value of the derivative instrument in excess of the cumulative change in the
present value of the future cash flows of the risk being hedged, if any, is
recognized in the current earnings during the period of change.

The Company's interest rate swap has been designated as a cash flow hedge and is
100% effective in hedging the exposure of variability in the future interest
payments attributable to the debt because the terms of the interest swap
correlate with the terms of the debt.

Gains and losses from termination of interest rate swap agreements are deferred
and amortized as an adjustment to interest expense over the original term of the
terminated swap agreement.

NOTE 2   NOTES PAYABLE AND LONG-TERM DEBT
- --------------------------------------------------------------------------------

At September 30, 2001, the Company had committed bank lines totaling $85
million; $50 million expires October 2003 and $35 million expires May 2002.
Additionally, the Company had uncommitted credit facilities totaling $10
million. Collectively, the Company had $50 million in outstanding borrowings and
outstanding letters of credit totaling $10.6 million against these lines at
September 30, 2001. As described above, concurrent with a $50 million borrowing
under the facility that expires October 2003, the Company entered into an
interest rate swap with a notional value of $50 million and an expiration date
of October 2003. The swap effectively converts this $50 million facility from a
floating rate of LIBOR plus 50 basis points to a fixed effective rate of 5.38
percent. Excluding the impact of the interest rate swap, the average interest
rate for the borrowings at September 30, 2001, was approximately 5.66 percent on
a 360 day basis.

Under the various credit agreements, the Company must meet certain requirements
regarding levels of debt, net worth and earnings.

NOTE 4  SHAREHOLDERS' EQUITY
- --------------------------------------------------------------------------------

In January 2000, the board of directors authorized the repurchase of up to
1,000,000 shares of the Company's common stock in the open market or private
transactions. The repurchased shares will be held in treasury and used for
general corporate purposes including use in the Company's benefit plans. During
fiscal 2001, the Company purchased 773,800 shares at a cost of approximately
$23,198,000 and in fiscal 2000 purchased 20,600 shares at a cost of
approximately $450,000. The Company did not purchase any shares is fiscal 1999.
As of September 30, 2001, the Company is authorized to repurchase up to 205,600
additional shares.

The Company has several plans providing for common-stock based awards to
employees and to non-employee directors. The plans permit the granting of
various types of awards including stock options and restricted stock. Awards may
be granted for no consideration other than prior and future services. The
purchase price per share for stock options may not be less than market price of
the underlying stock on the date of grant. Stock options expire ten years after
grant.

The Company has reserved 3,135,509 shares of its treasury stock to satisfy the
exercise of stock options issued under the 1990 and 1996 Stock Option Plans.
Effective after December 6, 2000, additional options are no longer granted under
these Plans. Options granted under the 1996 Plan vest over a four-year period.
In fiscal 2001, 843,800 options were granted under the 1996 Plan.

In March 2001, the Company adopted the 2000 Stock Incentive Plan (the "Stock
Incentive Plan"). The Stock Incentive Plan was effective December 6, 2000, and
will terminate December 6, 2010. Under this plan, the Company is authorized to
grant options for up to 3,000,000 shares of the Company's common stock at an
exercise price not less than the fair market value of the common stock on the
date of grant. Up to 450,000 shares of the total authorized may be granted to
participants as restricted stock awards. There was no activity under this plan
during fiscal 2001.

In fiscal 2000 and 1999, 10,000 and 17,000 shares of restricted stock,
respectively, were granted at a weighted-average price of $24.75 and $17.00,
respectively, which approximated fair market value at the date of grant.
Unearned compensation of $248,000 and $289,000 for fiscal 2000 and 1999,
respectively, is being amortized over a five-year period as compensation
expense. There were no restricted stock grants in fiscal 2001.

The following summary reflects the stock option activity and related information
(shares in thousands):

These pro forma amounts may not be representative of future disclosures since
the estimated fair value of stock options is amortized to expense over the
vesting period, and additional options may be granted in future years.

The weighted-average fair values of options at their grant date during 2001,
2000, and 1999 were $13.01, $10.80, and $6.81, respectively. The estimated fair
value of each option granted is calculated using the Black-Scholes
option-pricing model. The following summarizes the weighted-average assumptions
used in the model:

On September 30, 2001, the Company had 49,852,797 outstanding common stock
purchase rights ("Rights") pursuant to terms of the Rights Agreement dated
January 8, 1996. Under the terms of the Rights Agreement each Right entitled the
holder thereof to purchase from the Company one half of one unit consisting of
one one-thousandth of a share of Series A Junior Participating Preferred Stock
("Preferred Stock"), without par value, at a price of $90 per unit. The exercise
price and the number of units of Preferred Stock issuable on exercise of the
Rights are subject to adjustment in certain cases to prevent dilution. The
Rights will be attached to the common stock certificates and are not exercisable
or transferrable apart from the common stock, until ten business days after a
person acquires 15% or more of the outstanding common stock or ten business days
following the commencement of a tender offer or exchange offer that would result
in a person owning 15% or more of the outstanding common stock. In the event the
Company is acquired in a merger or certain other business combination
transactions (including one in which the Company is the surviving corporation),
or more than 50% of the Company's assets or earning power is sold or
transferred, each holder of a Right shall have the right to receive, upon
exercise of the Right, common stock of the acquiring company having a value
equal to two times the exercise price of the Right. The Rights are redeemable
under certain circumstances at $0.01 per Right and will expire, unless earlier
redeemed, on January 31, 2006. As long as the Rights are not separately
transferrable, the Company will issue one half of one Right with each new share
of common stock issued.

options to purchase 1,250,750 shares of common stock at a weighted-average price
of $33.84 were outstanding at September 30, 2001 but were not included in the
computation of diluted earnings per common share. Inclusion of these shares
would be antidilutive.

Notes payable bear interest at market rates and are carried at cost which
approximates fair value. The estimated fair value of the Company's interest rate
swap is ($1,590,553) at September 30, 2001, based on forward-interest rates
derived from the year-end yield curve as calculated by the financial institution
that is a counterparty to the swap. The estimated fair value of the Company's
available-for-sale securities is primarily based on market quotes.

The following is a summary of available-for-sale securities, which excludes
those accounted for under the equity method of accounting (see Note 1):

NOTE 11  RISK FACTORS
- --------------------------------------------------------------------------------

CONCENTRATION OF CREDIT -

Financial instruments which potentially subject the Company to concentrations of
credit risk consist primarily of temporary cash investments and trade
receivables. The Company places temporary cash investments with established
financial institutions and invests in a diversified portfolio of highly rated,
short-term money market instruments. The Company's trade receivables are
primarily with companies in the oil and gas industry. The Company normally does
not require collateral except for certain receivables of customers in its
natural gas marketing operations.

CONTRACT DRILLING OPERATIONS -

International drilling operations are significant contributors to the Company's
revenues and net profit. It is possible that operating results could be affected
by the risks of such activities, including economic conditions in the
international markets in which the Company operates, political and economic
instability, fluctuations in currency exchange rates, changes in international
regulatory requirements, international employment issues, and the burden of
complying with foreign laws. These risks may adversely affect the Company's
future operating results and financial position.

The Company believes that its rig fleet is not currently impaired based on an
assessment of future cash flows of the assets in question. However, it is
possible that the Company's assessment that it will recover the carrying amount
of its rig fleet from future operations may change in the near term.

OIL AND GAS OPERATIONS -

In estimating future cash flows attributable to the Company's exploration and
production assets, certain assumptions are made with regard to commodity prices
received and costs incurred. Due to the volatility of commodity prices, it is
possible that the Company's assumptions used in estimating future cash flows for
exploration and production assets may change in the near term.


                                                                              29


- --------------------------------------------------------------------------------
NOTE 12  NEW ACCOUNTING STANDARDS
- --------------------------------------------------------------------------------

Effective October 1, 2000, the Company adopted Statement of Financial Accounting
Standards No. 133 (SFAS 133), "Accounting for Derivative Instruments and Hedging
Activities," as amended, which establishes accounting and reporting standards
for derivative instruments, including certain derivative instruments embedded in
other contracts, and for hedging activities. SFAS 133, as amended, requires that
all derivatives be recorded on the balance sheet at fair value. Upon adoption at
October 1, 2000, the effect of complying with SFAS 133, as amended, was
immaterial to the Company's results of operations and financial position.

In June 2001, the FASB issued SFAS No. 143, "Accounting for Asset Retirement
Obligations." This Statement addresses financial accounting and reporting for
obligations associated with the retirement of tangible long-lived assets and the
associated asset retirement costs and amends FASB Statement No. 19, "Financial
Accounting and Reporting by Oil and Gas Producing Companies." The Statement
requires that the fair value of a liability for an asset retirement obligation
be recognized in the period in which it is incurred if a reasonable estimate of
fair value can be made, and that the associated asset retirement costs be
capitalized as part of the carrying amount of the long-lived asset. The
Statement is effective for financial statements issued for fiscal years
beginning after June 15, 2002. The effect of this standard on the Company's
results of operations and financial position is being evaluated.

In August 2001, the FASB issued SFAS No. 144, "Accounting for the Impairment or
Disposal of Long-Lived Assets." This Statement supersedes SFAS No. 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to
be Disposed of" and amends Accounting Principles Board Opinion No. 30,
"Reporting the Results of Operations - Reporting the Effects of Disposal of a
Segment of a Business and Extraordinary, Unusual and Infrequently Occurring
Events and Transactions." The Statement retains the basic framework of SFAS No.
121, resolves certain implementation issues of SFAS No. 121, extends
applicability to discontinued operations, and broadens the presentation of
discontinued operations to include a component of an entity. The Statement will
be applied prospectively and is effective for financial statements issued for
fiscal years beginning after December 15, 2001. Adoption of the Statement is not
expected to have any initial impact on the Company's results of operations or
financial position.

- --------------------------------------------------------------------------------

LITIGATION SETTLEMENT -

As previously discussed in the Company's filings on Forms 8-K dated March 16,
2001, and June 13, 2001, and in the Company's Form 10-Q filed on August 13,
2001, the Company is a defendant in Verdin v. R&B Falcon Drilling USA, Inc., et
al., a civil action in the United States District Court, Galveston, Texas. The
lawsuit alleges, among other things, that the company and many other defendant
companies whose collective operations represent a substantial majority of the
U.S. offshore drilling industry, conspired to fix wages and benefits paid to
drilling employees. Plaintiff contends that this alleged conduct violates
federal and state antitrust laws. Plaintiff sought treble damages, attorneys'
fees and costs on behalf of himself and an alleged class of offshore workers.

In May 2001, the Company reached an agreement in principle with Plaintiff's
counsel to settle all claims pending court approval of the settlement. In the
third quarter of fiscal 2001, the Company accrued $3.25 million to contract
drilling expense based on the pending settlement. The total settlement liability
is $10 million of which $6.75 million will be paid by the Company's insurer. The
Company does not believe that the settlement will have a material adverse affect
on its business or financial position.

KANSAS AD VALOREM SETTLEMENT -

In fiscal 1997, the Company was assessed with approximately $6.7 million of
Kansas ad valorem taxes which had been reimbursed to the Company for the period
from October 1983 through June 1988 by interstate pipelines transporting natural
gas to end users. In fiscal 1997, based on the assessment, natural gas revenues
were reduced by $2.7 million and interest expense was increased by $4.0 million.
In March 1998, approximately $6.1 million of the unpaid assessment was placed in
an escrow account pending resolution of this matter. Since March 1998, the
escrow account and the related liability continued to accrue interest income and
interest expense of approximately $1.0 million.

The Federal Energy Regulatory Commission approved settlements between the
Company and three of the pipelines. The last of these settlements was final in
May 2001. The Company paid approximately $3.9 million out of its escrow account
for the settlement of all three pipeline proceedings. The three settlements were
approximately $3.1 million less than the amount the Company accrued for this
liability. The impact of these settlements in the third quarter of fiscal 2001
was to increase natural gas revenues by approximately $1.1 million, reduce
interest expense by approximately $2.0 million and reduce the liability by $3.1
million. At September 30, 2001, the Company continues to escrow approximately
$337,000 to cover reimbursement liability in the remaining two pipeline
proceedings. The Company believes this amount will be adequate to cover future
reimbursement liability.

COMMITMENTS -

The Company, on a regular basis, makes commitments for the purchase of contract
drilling equipment. At September 30, 2001, the Company has commitments of
approximately $230 million for the purchase of drilling equipment.

NOTE 14  SEGMENT INFORMATION
- --------------------------------------------------------------------------------

The Company operates principally in the contract drilling industry, which
includes a Domestic segment and an International segment, and in the oil and gas
industry, which includes an Exploration and Production segment and a Natural Gas
Marketing segment. The contract drilling operations consist of contracting
Company-owned drilling equipment primarily to major oil and gas exploration
companies. The Company's primary international areas of operation include
Venezuela, Colombia, Ecuador, Argentina and Bolivia. Oil and gas activities
include the exploration for and development of productive oil and gas properties
located primarily in Oklahoma, Texas, Kansas, and Louisiana, as well as, the
marketing of natural gas for third parties. The Natural Gas Marketing segment
also markets most of the natural gas produced by the Exploration and Production
segment retaining a market based fee from the sale of such production. The
Company also has a Real Estate segment whose operations are conducted
exclusively in the metropolitan area of Tulsa, Oklahoma. The primary areas of
operations include a major shopping center and several multi-tenant warehouses.
Each reportable segment is a strategic business unit which is managed separately
as an autonomous business. Other includes investments in available-for-sale
securities and corporate operations. The "other" component of Total Assets also
includes the Company's investment in equity-owned investments.

The Company evaluates performance of its segments based upon operating profit or
loss from operations before income taxes which includes revenues from external
and internal customers; operating costs; depreciation, depletion and
amortization; dry holes and abandonments and taxes other than income taxes. The
accounting policies of the segments are the same as those described in Note 1,
Summary of Accounting Policies. Intersegment sales are accounted for in the same
manner as sales to unaffiliated customers.

Estimated Quantities of Proved Oil and Gas Reserves (Unaudited) -

Proved reserves are estimated quantities of crude oil, natural gas, and natural
gas liquids which geological and engineering data demonstrate with reasonable
certainty to be recoverable in future years from known reservoirs under existing
economic and operating conditions. Proved developed reserves are those which are
expected to be recovered through existing wells with existing equipment and
operating methods. The following is an analysis of proved oil and gas reserves
as estimated by Netherland, Sewell & Associates, Inc. at September 30, 2001 and
2000. Amounts at September 30, 1999 were estimated by the Company and reviewed
by independent engineers.

Standardized Measure of Discounted Future Net Cash Flows Relating to Proved Oil
and Gas Reserves (Unaudited) -

The "Standardized Measure of Discounted Future Net Cash Flows Relating to Proved
Oil and Gas Reserves" (Standardized Measure) is a disclosure requirement under
Financial Accounting Standards Board Statement No. 69 "Disclosures About Oil and
Gas Producing Activities". The Standardized Measure does not purport to present
the fair market value of a company's proved oil and gas reserves. This would
require consideration of expected future economic and operating conditions,
which are not taken into account in calculating the Standardized Measure.

Under the Standardized Measure, future cash inflows were estimated by applying
year-end prices to the estimated future production of year-end proved reserves.
Future cash inflows were reduced by estimated future production and development
costs based on year-end costs to determine pre-tax cash inflows. Future income
taxes were computed by applying the statutory tax rate to the excess of pre-tax
cash inflows over the Company's tax basis in the associated proved oil and gas
properties. Tax credits and permanent differences were also considered in the
future income tax calculation. Future net cash inflows after income taxes were
discounted using a ten percent annual discount rate to arrive at the
Standardized Measure.

Gross profit represents total revenues less operating costs, depreciation,
depletion and amortization, dry holes and abandonments, and taxes, other than
income taxes.

The sum of earnings per share for the four quarters may not equal the total
earnings per share for the year due to changes in the average number of common
shares outstanding.

Net income in the second quarter of 2001 includes an after-tax charge of $2.4
million ($0.05 per share, on a diluted basis) related to the write-down of
producing properties in accordance with SFAS No. 121.

HELMERICH & PAYNE, INC.

The Board of Directors and Shareholders
Helmerich & Payne, Inc.

  We have audited the accompanying consolidated balance sheets of Helmerich &
Payne, Inc. as of September 30, 2001 and 2000, and the related consolidated
statements of income, shareholders' equity, and cash flows for each of the three
years in the period ended September 30, 2001. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

  We conducted our audits in accordance with auditing standards generally
accepted in the United States. Those standards require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

  In our opinion, the financial statements referred to above present fairly, in
all material respects, the consolidated financial position of Helmerich & Payne,
Inc. at September 30, 2001 and 2000, and the consolidated results of its
operations and its cash flows for each of the three years in the period ended
September 30, 2001, in conformity with accounting principles generally accepted
in the United States.
