PART I

ITEM 1. BUSINESS
- --------------------------------------------------------------------------------
Helmerich & Payne, Inc. (the "Company"), was incorporated under the laws of the
State of Delaware on February 3, 1940, and is successor to a business originally
organized in 1920. The Company is primarily engaged in contract drilling of oil
and gas wells for others. The contract drilling business accounts for the major
portion of its operating revenues. The Company is also engaged in the ownership,
development, and operation of commercial real estate.

The Company is organized into two separate autonomous operating entities being
contract drilling and real estate. Both businesses operate independently of the
other. Both the contract drilling and real estate businesses are conducted
through wholly-owned subsidiaries. Operating decentralization is balanced by a
centralized finance division, which handles all accounting, data processing,
budgeting, insurance, cash management, and related activities.

The Company's domestic contract drilling is conducted primarily in Oklahoma,
Texas, Wyoming, and Louisiana, and offshore from platforms in the Gulf of Mexico
and offshore California. The Company has also operated during fiscal 2002 in six
international locations: Venezuela, Ecuador, Colombia, Argentina, Bolivia and
Equatorial Guinea.

The Company's real estate investments are located in Tulsa, Oklahoma, where the
Company has its executive offices.

Prior to October 1, 2002, the Company was engaged in the exploration, production
and sale of crude oil and natural gas business ("exploration and production
business"). During fiscal 2002, the Company transferred assets and liabilities
of the exploration and production business to its wholly-owned subsidiary,
Cimarex Energy Co. On September 30, 2002, the Company distributed the common
stock of Cimarex Energy Co. to the Company's stockholders and completed a merger
of Key Production Company, Inc. with a subsidiary of Cimarex Energy Co. See
pages 5 through 6 of this report for a more detailed discussion of the spin-off
and merger.

CONTRACT DRILLING
- --------------------------------------------------------------------------------
The Company believes that it is one of the major land and offshore platform
drilling contractors in the western hemisphere. Operating principally in North
and South America, the Company specializes primarily in deep drilling in major
gas producing basins of the United States and in drilling for oil and gas in
remote international areas. For its international operations, the Company
operates certain rigs which are transportable by helicopter. In the United
States, the Company draws its customers primarily from the major oil companies
and the larger independents. In South America, the Company's current customers
include the Venezuelan state petroleum company and major international oil
companies.

In fiscal 2002, the Company received approximately 70% of its consolidated
revenues from the Company's ten largest contract drilling customers. BP plc,
Shell Oil Company and ExxonMobil Corporation, including their affiliates, are
the Company's three largest contract drilling customers. The Company performs
drilling services for BP plc, Shell Oil Company and ExxonMobil Corporation on a
world-wide basis. Revenues from drilling services performed for BP plc, Shell
Oil Company and ExxonMobil Corporation in fiscal 2002 accounted for
approximately 16%, 15% and 12%, respectively, of the Company's consolidated
revenues from continuing operations for the same period. While the Company
believes that its relationship with all of these customers is good, the loss of
BP plc, Shell Oil Company and ExxonMobil Corporation or a loss of one or more of
its larger customers would have a material adverse effect on the drilling
subsidiary and the Company.

The Company provides drilling rigs, equipment, personnel, and camps on a
contract basis. These services are provided so that the Company's customers may
explore for and develop oil and gas from onshore areas and from fixed platforms,
tension leg platforms and spars in offshore areas. Each of the drilling rigs
consists of engines, drawworks, a mast, pumps, blowout preventers, a
drillstring, and related equipment. The intended well depth


                                       1


and the drilling site conditions are the principal factors that determine the
size and type of rig most suitable for a particular drilling job. A land
drilling rig may be moved from location to location without modification to the
rig. A helicopter rig is one that can be disassembled into component part loads
of approximately 4,000-20,000 pounds and transported to remote locations by
helicopter, cargo plane, or other means. Conversely, a platform rig is
specifically designed to perform drilling operations upon a particular platform.
While a platform rig may be moved from its original platform, significant
expense is incurred to modify a platform rig for operation on each subsequent
platform. In addition to traditional platform rigs, the Company operates
self-moving minimum space platform drilling rigs and drilling rigs to be used on
tension leg platforms and spars. The minimum space rig is designed to be moved
without the use of expensive derrick barges. The tension leg platforms and spars
allow drilling operations to be conducted in much deeper water than traditional
fixed platforms.

The Company's workover rigs are equipped with engines, drawworks, a mast, pumps,
and blowout preventers. A workover rig is used to complete a new well after the
hole has been drilled by a drilling rig, and to remedy various downhole
problems that occur in producing wells.

During fiscal 1998, the Company put to work a new generation of six highly
mobile/depth flexible rigs (individually the "FlexRig"(TM)). The FlexRig has
been able to significantly reduce average rig move times compared to similar
depth rated traditional land rigs. In addition, the FlexRig allows a greater
depth flexibility of between 8,000 to 18,000 feet and provides greater operating
efficiency. During fiscal 2000, the Company ordered 12 new FlexRigs at an
approximate cost of between $7,500,000 and $8,250,000 each. The Company took
delivery of 10 new FlexRigs through calendar 2001. During fiscal 2001, the
Company ordered an additional 25 new FlexRigs at an approximate cost of
$11,000,000 each. These new rigs, known as "FlexRig3", are the next generation
of FlexRigs which incorporate new drilling technology and new environmental and
safety design. This new design includes integrated top drive, AC electric drive,
hydraulic BOP handling system, hydraulic tubular make-up and break-out system,
split crown and traveling blocks and an enlarged drill floor for the enabling of
simultaneous crew activities. The Company took delivery of eight FlexRig3 rigs
as of the end of September, 2002. The remaining FlexRig3 rigs are expected to be
delivered by the end of fiscal 2003. The FlexRig3's will be available for work
in the Company's domestic and international drilling operations.

The Company's drilling contracts are obtained through competitive bidding or as
a result of negotiations with customers, and sometimes cover multi-well and
multi-year projects. Each drilling rig operates under a separate drilling
contract. Most of the contracts are performed on a "daywork" basis, under which
the Company charges a fixed rate per day, with the price determined by the
location, depth, and complexity of the well to be drilled, operating conditions,
the duration of the contract, and the competitive forces of the market. The
Company has previously performed contracts on a combination "footage" and
"daywork" basis, under which the Company charged a fixed rate per foot of hole
drilled to a stated depth, usually no deeper than 15,000 feet, and a fixed rate
per day for the remainder of the hole. Contracts performed on a "footage" basis
involve a greater element of risk to the contractor than do contracts performed
on a "daywork" basis. Also, the Company has previously accepted "turnkey"
contracts under which the Company charges a fixed sum to deliver a hole to a
stated depth and agrees to furnish services such as testing, coring, and casing
the hole which are not normally done on a "footage" basis. "Turnkey" contracts
entail varying degrees of risk greater than the usual "footage" contract. The
Company did not accept any "footage" or "turnkey" contracts during fiscal 2002.
The Company believes that under current market conditions "footage" and
"turnkey" contract rates do not adequately compensate contractors for the added
risks. The duration of the Company's drilling contracts are "well-to-well" or
for a fixed term. "Well-to-well" contracts are cancelable at the option of
either party upon the completion of drilling at any one site. Fixed-term
contracts customarily provide for termination at the election of the customer,
with an "early termination payment" to be paid to the contractor if a contract
is terminated prior to the expiration of the fixed term.

While current fixed term contracts are for one to five year periods, some fixed
term and well-to-well contracts are expected to be continued for longer periods
than the original terms. However, the contracting parties have no legal
obligation to extend the contracts. Contracts generally contain renewal or
extension provisions exercisable at the




                                       2

option of the customer at prices mutually agreeable to the Company and the
customer. In most instances contracts provide for additional payments for
mobilization and demobilization. Contracts for work in foreign countries
generally provide for payment in United States dollars, except for amounts
required to meet local expenses. However, government owned petroleum companies
are more frequently requesting that a greater proportion of these payments be
made in local currencies. See Regulations, Hazards and Risks on page 4 of this
report.

DOMESTIC DRILLING
- --------------------------------------------------------------------------------
The Company believes it is a major land and offshore platform drilling
contractor in the domestic market. At the end of September, 2002, the Company
had 78 of its rigs (66 land rigs and 12 platform rigs) available for work in the
United States and had management contracts for three customer-owned rigs. The 19
rig increase from fiscal 2001 to 2002 is due to the delivery of 13 new FlexRigs,
transfer of four rigs from the Company's international operations, and the
construction of two self-moving platform rigs.

While the Company commenced drilling operations in the Gulf of Mexico with two
new self-moving platform rigs, the Company stacked five platform rigs during
fiscal 2002.

INTERNATIONAL DRILLING
- --------------------------------------------------------------------------------
The Company's international drilling operations began in 1958 with the
acquisition of the Sinclair Oil Company's drilling rigs in Venezuela. Helmerich
& Payne de Venezuela, C.A., a wholly owned subsidiary of the Company, is one of
the leading drilling contractors in Venezuela. Beginning in 1972, with the
introduction of its first helicopter rig, the Company expanded into other Latin
American countries.

Venezuelan operations continue to be a significant part of the Company's
operations. At the end of fiscal 2002, the Company owned and operated 14 land
drilling rigs in Venezuela with a utilization rate of approximately 41% for the
fiscal year. The Company worked for the Venezuelan state petroleum company
during fiscal 2002, and revenues from this work accounted for approximately
4.6% of the Company's consolidated revenues from continuing operations during
the fiscal year. In addition, the Company has performed contract drilling
services in Venezuela for two independent oil companies during fiscal 2002.

The Company's rig utilization rate in Venezuela has increased from approximately
37% during fiscal 2001 to approximately 41% in fiscal 2002. Even though the
Company is, at this time, unable to predict future fluctuations in its
utilization rates during fiscal 2003, the Company believes that the prospects
are good for returning at least five of its idle rigs back to work in Venezuela
during fiscal 2003.

During fiscal 2002, one rig was moved into Ecuador from the United States. At
the end of fiscal 2002, the Company owned and operated eight rigs in Ecuador.
The Company's utilization rate was approximately 93% during fiscal 2002.
Revenues generated by Ecuadorian drilling operations contributed approximately
8.89% of the Company's consolidated revenues from continuing operations. The
contracts are with large international oil companies.

During fiscal 2002, the Company owned and operated three drilling rigs in
Colombia. The Company's utilization rate in Colombia was approximately 31%
during fiscal 2002. The revenues generated by Colombian drilling operations
contributed approximately 1.87% of the Company's consolidated revenues in fiscal
2002 from continuing operations. The Company is not presently operating any rigs
in Colombia, but expects to resume drilling operations with one rig in January,
2003.

In addition to its operations in Venezuela, Ecuador and Colombia, the Company in
fiscal 2002 owned and operated six rigs in Bolivia and two rigs in Argentina.
However, at the end of fiscal 2002, only one rig was operating in Bolivia and no
rigs were operating in Argentina. During fiscal 2002, the Company continued
operations under a management contract for a customer-owned platform rig
located offshore Equatorial Guinea.



                                       3


COMPETITION
- --------------------------------------------------------------------------------
The contract drilling business is highly competitive. Competition in contract
drilling involves such factors as price, rig availability, efficiency, condition
of equipment, reputation, operating safety and customer relations. Competition
is primarily on a regional basis and may vary significantly by region at any
particular time. Land drilling rigs can be readily moved from one region to
another in response to changes in levels of activity, and an oversupply of rigs
in any region may result.

Although many contracts for drilling services are awarded based solely on price,
the Company has been successful in establishing long-term relationships with
certain customers which have allowed the Company to secure drilling work even
though the Company may not have been the lowest bidder for such work. The
Company has continued to attempt to differentiate its services based upon its
engineering design expertise, operational efficiency, safety and environmental
awareness. This strategy is less effective when lower demand for drilling
services intensifies price competition and makes it more difficult or impossible
to compete on any other basis than price.

REGULATIONS, HAZARDS AND RISKS
- --------------------------------------------------------------------------------
The drilling operations of the Company are subject to the many hazards inherent
in the business, including inclement weather, blowouts and well fires. These
hazards could cause personal injury, suspend drilling operations, seriously
damage or destroy the equipment involved, and cause substantial damage to
producing formations and the surrounding areas. The Company's offshore platform
drilling operations are also subject to potentially greater environmental
liability, adverse sea conditions and platform damage or destruction due to
collision with aircraft or marine vessels.

The Company believes that it has adequate insurance coverage for comprehensive
general liability, public liability, property damage, workers compensation and
employer's liability. No insurance is carried against loss of earnings or
business interruption. The Company is unable to obtain significant amounts of
insurance to cover risks of underground reservoir damage; however, the Company
is generally indemnified under its drilling contracts from this risk. The
majority of the Company's insurance coverage has been purchased through fiscal
2003; however, rates and deductibles increased substantially for a number of
coverages due to general hardening in the energy insurance market. In view of
these present conditions, no assurance can be given that all or a portion of the
Company's coverage will not be cancelled during fiscal 2003 or that insurance
coverage will continue to be available at rates considered reasonable.

The Company's operations can be materially affected by low oil and gas prices.
The Company believes that any significant reduction in oil and gas prices could
result in a corresponding decline in demand for the Company's services. Any
prolonged reduction in demand for the Company's services could have a material
and adverse effect on the Company.

International operations are subject to certain political, economic, and other
uncertainties not encountered in domestic operations, including increased risks
of terrorism, kidnapping of employees, expropriation of equipment as well as
expropriation of a particular oil company operator's property and drilling
rights, taxation policies, foreign exchange restrictions, currency rate
fluctuations, and general hazards associated with foreign sovereignty over
certain areas in which operations are conducted. There can be no assurance that
there will not be changes in local laws, regulations, and administrative
requirements or the interpretation thereof which could have a material adverse
effect on the profitability of the Company's operations or on the ability of the
Company to continue operations in certain areas. Because of the
impact of local laws, the Company's future operations in certain areas may be
conducted through entities in which local citizens own interests and through
entities (including joint ventures) in which the Company holds only a minority
interest, or pursuant to arrangements under which the Company conducts
operations under contract to local entities. While the Company believes that
neither operating through such entities nor pursuant to such arrangements would
have a material adverse effect on the Company's operations or revenues, there
can be no assurance that the Company will in all cases be able to structure or
restructure its operations to




                                       4

conform to local law (or the administration thereof) on terms acceptable to the
Company. The Company further attempts to minimize the potential impact of such
risks by operating in more than one geographical area.

During fiscal 2002, approximately 27% of the Company's consolidated revenues
from continuing operations were generated from the international contract
drilling business. Approximately 91% of the international revenues were from
operations in South America and approximately 67% of South American revenues
were from Venezuela and Ecuador. Based upon current information, the Company
believes that exposure to potential losses from currency devaluation is minimal
in Colombia, Ecuador and Bolivia. In those countries, all receivables and
payments are currently in U.S. dollars. Cash balances are kept at a minimum
which assists in reducing exposure.

In January, 2002, Argentina suffered a 60% devaluation of the peso. The
Argentine government required that all payments under all contracts were to be
immediately converted to Argentine pesos and that contracting parties would
share in the currency losses. The Company recorded a currency loss of
US$1,200,000 in the first quarter of the fiscal year 2002 to recognize the loss
of value in its accounts receivable. The Company has completed negotiations with
its customers and has secured agreements that limit the portion of the accounts
receivable that will be paid in pesos with the balance of such accounts
receivable to be paid in U.S. dollars. Based upon such agreements, the Company
does not expect significant Argentine currency losses in fiscal 2003.

In Venezuela, approximately 60% of the Company's invoice billings are in U.S.
dollars and 40% are in the local currency, the bolivar. The Company is exposed
to risks of currency devaluation in Venezuela as a result of bolivar receivable
balances and necessary bolivar cash balances. From August of 2001 to August of
2002, there was a 92% devaluation of the bolivar. As a result, the Company
experienced a US$4,393,000 devaluation loss. The Company is unable to predict
future devaluation in Venezuela. In the event that fiscal 2003 activity levels
are similar to fiscal 2002 and if a 25% to 100% devaluation would occur, the
Company could experience potential currency devaluation losses ranging from
approximately US$1,700,000 to US$4,200,000.

Recent events in Venezuela have created greater governmental instability. In the
event that labor strikes continue or turmoil increases, the Company could
experience shortages in material and supplies necessary to operate some or all
of its Venezuelan drilling rigs.

During the mid-1970s, the Venezuelan government nationalized the exploration and
production business. At the present time it appears the Venezuelan government
will not nationalize the contract drilling business. Any such nationalization
could result in the Company's loss of all or a portion of its assets and
business in Venezuela.

Many aspects of the Company's operations are subject to government regulation,
including those relating to drilling practices and methods and the level of
taxation. In addition, various countries (including the United States) have
environmental regulations which affect drilling operations. Drilling contractors
may be liable for damages resulting from pollution. Under United States
regulations, drilling contractors must establish financial responsibility to
cover potential liability for pollution of offshore waters. Generally, the
Company is indemnified under drilling contracts from liability arising from
pollution, except in certain cases of surface pollution. However, the
enforceability of indemnification provisions in foreign countries may be
questionable.

The Company believes that it is in substantial compliance with all legislation
and regulations affecting its operations in the drilling of oil and gas wells
and in controlling the discharge of wastes. To date, compliance has not
materially affected the capital expenditures, earnings, or competitive position
of the Company, although these measures may add to the costs of operating
drilling equipment in some instances. Additional legislation or regulation may
reasonably be anticipated, and the effect thereof on operations cannot be
predicted.

EXPLORATION AND PRODUCTION
- --------------------------------------------------------------------------------
On February 23, 2002, the Company and Key Production Company, Inc. entered into
an Agreement and Plan of Merger and related agreements, including a
Distribution Agreement between the Company and Cimarex Energy Co. The agreements
provided for the consolidation of the Company's exploration and production
business under


                                       5

Cimarex Energy Co.; the distribution of Cimarex Energy Co. common stock to the
Company's stockholders; and the merger of Key Production Company, Inc. with a
subsidiary of Cimarex Energy Co.

As a part of this transaction, Cimarex Energy Co. agreed to defend and indemnify
the Company against all losses or liabilities arising out of or related to the
exploration and production business that was transferred by the Company to
Cimarex Energy Co. In July of 2002, the Company obtained a Private Letter Ruling
from the Internal Revenue Service to the effect that the contribution and
transfer of the assets and liabilities of the Company's exploration and
production business to Cimarex Energy Co. and the distribution by the Company of
all the shares of Cimarex Energy Co. common stock to the holders of the
Company's common stock would generally be treated as a tax-free transaction for
U.S. federal income tax purposes.

On September 30, 2002, the Company's distribution of Cimarex Energy Co. common
stock and the subsequent merger of Key Production Company, Inc. was completed.
Upon completion of the merger, approximately 65.25% of the Cimarex Energy Co.
common stock on a diluted basis was held by former stockholders of the Company.
Subsequent to this transaction, the Company and its subsidiaries will continue
to own and operate the contract drilling and real estate businesses, and Cimarex
Energy Co. will be a separate, publicly-traded company that will own and operate
the exploration and production business. The Company does not own any common
stock of Cimarex Energy Co.

REAL ESTATE OPERATIONS
- --------------------------------------------------------------------------------
The Company's real estate operations are conducted exclusively within the
metropolitan area of Tulsa, Oklahoma. Its major holding is Utica Square Shopping
Center, consisting of fourteen separate buildings, with parking and other common
facilities covering an area of approximately 30 acres. These buildings provide
approximately 405,709 square feet of net leasable retail sales and storage space
(80% of which is currently leased) and approximately 18,590 square feet of net
leasable general office space (99% of which is currently leased). Approximately
24% of the general office space is occupied by the Company's real estate
operations. Occupancy in the Shopping Center has decreased from 97% in fiscal
2001 to 80% in fiscal 2002 due to the closing of a large department store. In
calendar 2003, the Company intends to renovate the vacated department store
space containing approximately 75,000 square feet and convert such space to
multi-tenant specialty store use. In March of 2002, an eight-story medical
office building containing approximately 76,000 square feet of net leasable
space and located in Utica Square was demolished. The Company is currently
redeveloping the site. The new development is expected to include two new
upscale restaurants and additional customer parking.

At the end of the 2002 fiscal year, the Company owned 11 of a total of 73 units
in The Yorktown, a 16-story luxury residential condominium with approximately
150,940 square feet of living area located on a six-acre tract adjacent to Utica
Square Shopping Center. Three of the Company's units are currently leased.

The Company owns an eight-story office building located diagonally across the
street from Utica Square Shopping Center, containing approximately 87,000 square
feet of net leasable general office space. This building houses the Company's
principal executive offices.

The Company also owns and leases to third-parties multi-tenant warehouse space.
Three warehouses known as Space Center, each containing approximately 165,000
square feet of net leasable space, are situated in the southeast part of Tulsa
at the intersection of two major limited-access highways. Present occupancy is
100%. The Company also owns approximately 1.5 acres of undeveloped land lying
adjacent to such warehouses.

At the end of fiscal 2002, the Company owned approximately 235.2 acres in
Southpark consisting of approximately 225.1 acres of undeveloped real estate
(net of the 2.87 acre sale and condemnation proceeding described below) and
approximately 13 acres of multi-tenant warehouse area. The warehouse area is
known as Space Center East and consists of two warehouses, one containing
approximately 90,000 square feet and the other containing approximately 112,500
square feet. Present occupancy is 93%. The Company believes that a high quality

office park, with peripheral commercial, office/warehouse, and hotel sites, is
the best development use for the remaining land. However, no development plans
are currently pending.

In April of 2002, the Company sold approximately 2.87 acres of undeveloped land
in Southpark for $437,325.

The Company is a party to a condemnation proceeding initiated during fiscal 2000
by the Oklahoma Department of Transportation ("ODOT") which seeks to acquire
approximately 15.14 acres of undeveloped real property adjacent to a major
expressway in Southpark. This matter was settled in fiscal 2002 subject to the
execution of a mutually acceptable journal entry of judgment. As a result of the
settlement, the Company will be required to reimburse $275,000 of the $2,800,000
purchase price previously paid by ODOT.

The Company also owns a five-building complex called Tandem Business Park. The
project is located adjacent to and east of the Space Center East facility and
contains approximately six acres, with approximately 88,084 square feet of
office/warehouse space. Occupancy has decreased from 94% to 80% during fiscal
2002. The Company also owns a twelve-building complex, consisting of
approximately 204,600 square feet of office/warehouse space, called Tulsa
Business Park. The project is located south of the Space Center facility,
separated by a city street, and contains approximately 12 acres. During fiscal
2002, occupancy has increased from 93% to 96%.

The Company also owns two service center properties located adjacent to arterial
streets in south central Tulsa. The first, called Maxim Center, consists of one
office/warehouse building containing approximately 40,800 square feet and
located on approximately 2.5 acres. During fiscal 2002, occupancy has remained
at 94%. The second, called Maxim Place, consists of one office/warehouse
building containing approximately 33,750 square feet and located on
approximately 2.25 acres. During fiscal 2002, occupancy has remained at 17%.

COMPETITION
- --------------------------------------------------------------------------------
The Company has numerous competitors in the multi-tenant leasing business. The
size and financial capacity of these competitors range from one property sole
proprietors to large international corporations. The primary competitive factors
include price, location and configuration of space. The Company's competitive
position is enhanced by the location of its properties, its financial capability
and the long-term ownership of its properties. However, many competitors have
financial resources greater than the Company and have more contemporary
facilities.

communicated to the Company's management, and made known to the Company's Chief
Executive Officer and Chief Financial Officer, particularly during the period
