                    HELMERICH & PAYNE, INC. AND SUBSIDIARIES
              Annual Report Pursuant to Section 13 or 15(d) of the
                         Securities Exchange Act of 1934
                  For the Fiscal Year Ended September 30, 1999

                                     PART I

Item 1.  BUSINESS

         Helmerich & Payne, Inc. (the "Registrant"), was incorporated under the
laws of the State of Delaware on February 3, 1940, and is successor to a
business originally organized in 1920. Registrant is primarily engaged in the
exploration, production, and sale of crude oil and natural gas and in contract
drilling of oil and gas wells for others. These activities account for the major
portion of its operating revenues. The Registrant is also engaged in the
ownership, development, and operation of commercial real estate.

         The Registrant is organized into three separate autonomous operating
divisions being contract drilling; oil & gas operations; and real estate. While
there is a limited amount of intercompany activity, each division operates
essentially independently of the others. Each of the divisions, except
exploration and production, conducts their respective business 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.
   4

         Most of the Registrant's current exploration efforts are concentrated
in Louisiana, Oklahoma, Texas, and the Hugoton Field of western Kansas. The
Registrant also explores from time to time in the Rocky Mountain area, New
Mexico, Alabama, Michigan, and Mississippi. Substantially all of the
Registrant's gas production is sold to and resold by its marketing subsidiary.
This subsidiary also purchases gas from unaffiliated third parties for resale.

         The Registrant's domestic contract drilling is conducted primarily in
Oklahoma, Texas, and Louisiana, and offshore from platforms in the Gulf of
Mexico and offshore California. The Registrant has also operated during fiscal
1999 in six international locations: Venezuela, Ecuador, Colombia, Peru,
Argentina and Bolivia. In the second quarter of fiscal 2000, the Registrant
expects to operate a customer-owned offshore platform rig in Equatorial Guinea.

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

         CONTRACT DRILLING

         The Registrant 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 Registrant specializes 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 Registrant
operates certain rigs which are transportable by helicopter. In the United
States, the Registrant draws its customers primarily from the major oil
companies and the larger independents. The Registrant also drills for its own
oil and gas division. In South America, the Registrant's current customers

                                      I - 2

   5




include the Venezuelan state petroleum company and major international oil
companies.

         In fiscal 1999, Registrant received approximately 57% of its
consolidated revenues from the Registrant's ten largest contract drilling
customers. BP Amoco and Shell Oil Co., including their affiliates,
(respectively, "BPA" and "Shell") are the Registrant's two largest contract
drilling customers. The Registrant performs drilling services for BPA and Shell
on a world-wide basis. Revenues from drilling services performed for BPA and
Shell in fiscal 1999 accounted for approximately 18% and 12%, respectively, of
the Registrant's consolidated revenues for the same period. While the Registrant
believes that its relationship with all of these customers is good, the loss of
BPA or Shell or a simultaneous loss of several of its larger customers would
have a material adverse effect on the drilling subsidiary and the Registrant.

         The Registrant provides drilling rigs, equipment, personnel, and camps
on a contract basis. These services are provided so that Registrant's customers
may explore for and develop oil and gas from onshore areas and from fixed
platforms 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 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. 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

                                      I - 3

   6




platform. In addition to traditional platform rigs, Registrant operates self-
moving minimum space platform drilling rigs and drilling rigs to be used on
tension leg platforms. The minimum space rig is designed to be moved without the
use of expensive derrick barges. The tension leg platform rig allows drilling
operations to be conducted in much deeper water than traditional fixed
platforms. 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.

         The Registrant'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.

         The Registrant'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 Registrant 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 Registrant has previously performed contracts on a
combination "footage" and "daywork" basis, under which the Registrant 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

                                      I - 4

   7




Registrant has previously accepted "turnkey" contracts under which the
Registrant 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. Registrant has not accepted a
"footage" or "turnkey" contract during fiscal 1999. The Registrant believes that
under current market conditions "footage" and "turnkey" contract rates do not
adequately compensate contractors for the added risks. The duration of the
Registrant'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 three 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 option of the customer at prices
mutually agreeable to the Registrant 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

                                      I - 5

   8




greater proportion of these payments be made in local currencies.  See
Regulations and Hazards, page I-8.

         Domestic Drilling

         The Registrant believes it is a major land and offshore platform
drilling contractor in the domestic market. At the end of September, 1999, the
Registrant had 50 (40 land rigs and 10 platform rigs) of its rigs operating in
the United States and had management contracts for two customer-owned rigs.

         During fiscal 1999, four land rigs and one platform rig were relocated
from the Registrant's operations in Venezuela to the Registrant's domestic
operations. In November of 1999, Registrant returned one of such land rigs to
Venezuela. In addition, one of the Registrant's older platform rigs was sold.

         International Drilling

         The Registrant'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
Registrant, is one of the leading drilling contractors in Venezuela. Beginning
in 1972, with the introduction of its first helicopter rig, the Registrant
expanded into other Latin American countries.

         Venezuelan operations continue to be a significant part of the
Registrant's operations. At the end of fiscal 1999, the Registrant owned and
operated 18 land drilling rigs in Venezuela with a utilization rate of 36% for
such fiscal year. The Registrant worked for the Venezuelan State Petroleum
Company during fiscal 1999, and revenues from this work accounted for
approximately 6% of the Registrant's consolidated revenues during the fiscal
year.

                                      I - 6

   9




         Registrant's rig utilization rate in Venezuela has decreased from
approximately 92% during the 1998 fiscal year to approximately 36% in fiscal
1999. This reduction in utilization is primarily due to curtailed production and
development activities resulting from a reduction in worldwide oil prices. At
this time, the Registrant is unable to predict future fluctuations in its
utilization rates during fiscal 2000.

         The Venezuelan government, in early 1996, permitted foreign exploration
and production companies to acquire rights to explore for and produce oil and
gas in Venezuela. Registrant has performed contract drilling services in
Venezuela for six independent oil companies during fiscal 1999.

         At the end of fiscal 1999, the Registrant owned and operated ten
drilling rigs in Colombia. The Registrant's utilization rate was 71% during
fiscal 1999. During fiscal 1999 the revenue generated by Colombian drilling
operations contributed approximately 10.8% of the Registrant's consolidated
revenues.

         In addition to its operations in Venezuela and Colombia, the Registrant
in fiscal 1999 owned and operated four rigs in Ecuador, five rigs in Bolivia,
and two rigs in Argentina. In Ecuador, Bolivia and Argentina, the contracts are
with large international oil companies.

         Drilling operations ended during 1999 on a joint venture platform rig
in Australia. The rig is owned 50% by the Registrant and 50% by Registrant's
equity affiliate, Atwood Oceanics, Inc.

         Competition

         The contract drilling business is highly competitive. Competition in
contract drilling involves such factors as price, rig availability, efficiency,
condition of equipment, reputation, and customer relations. Competition is

                                      I - 7

   10




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 Registrant has been successful in establishing long-term
relationships with certain customers which have allowed the Registrant to secure
drilling work even though the Registrant may not have been the lowest bidder for
such work. The Registrant has continued to attempt to differentiate its services
based upon its engineering design expertise, operational efficiency, safety and
environmental awareness.

         Regulations and Hazards

         The drilling operations of the Registrant are subject to the many
hazards inherent in the business, including 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 Registrant believes that it has adequate insurance coverage for
comprehensive general liability, public liability, property damage (including
insurance against loss by fire and storm, blowout, and cratering risks), workers
compensation and employer's liability. No insurance is carried against loss of
earnings or business interruption. The Registrant is unable to obtain
significant amounts of insurance to cover risks of underground reservoir damage;
however, the Registrant is generally indemnified under its drilling contracts
from this risk. The Registrant's present insurance coverage has been secured

                                      I - 8

   11




through fiscal 2000. However, in view of conditions generally in the liability
insurance industry, no assurance can be given that the Registrant's present
coverage will not be cancelled during fiscal 2000 nor that insurance coverage
will continue to be available at rates considered reasonable.

         International operations are subject to certain political, economic,
and other uncertainties not encountered in domestic operations, including risks
of 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
Registrant's operations or on the ability of the Registrant to continue
operations in certain areas. Because of the impact of local laws, the
Registrant'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 Registrant holds only a minority interest, or
pursuant to arrangements under which the Registrant conducts operations under
contract to local entities. While the Registrant believes that neither operating
through such entities nor pursuant to such arrangements would have a material
adverse effect on the Registrant's operations or revenues, there can be no
assurance that the Registrant will in all cases be able to structure or
restructure its operations to conform to local law (or the administration
thereof) on terms acceptable to the Registrant. The Registrant further attempts
to minimize the potential

                                      I - 9

   12




impact of such risks by operating in more than one geographical area and by
attempting to obtain indemnification from operators against expropriation,
nationalization, and deprivation.

         During fiscal 1999, approximately 32% of the Registrant's consolidated
revenues were generated from the international contract drilling business. Over
95% of the international revenues were from Venezuela, Colombia, Bolivia,
Ecuador and Argentina. Exposure to potential losses from currency devaluation is
minimal in the above-mentioned countries except for Venezuela. 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 Venezuela, approximately 60% of the Registrant's invoice billings
are in U.S. dollars and the other 40% are in the local currency, the bolivar.
The Registrant is exposed to risks of currency devaluation in Venezuela as a
result of bolivar receivable balances and necessary bolivar cash balances. In
1994, the Venezuelan government established a fixed exchange rate in hopes of
stemming economic problems caused by a high rate of inflation. During the first
week of December, 1995, the government established a new exchange rate,
resulting in further devaluation of the bolivar. In April of 1996, the bolivar
was again devalued when the government decided to abolish its fixed rate policy
and to allow a floating market exchange rate. During fiscal 1998, the Registrant
experienced losses of approximately US$2,204,000 and in fiscal 1999 it
experienced losses of US$712,000 as a result of the devaluation of the bolivar.
Registrant is unable to predict future devaluation in Venezuela. In the event a
25% to 50% devaluation would occur, the Registrant could experience potential
currency valuation losses ranging from approximately US$350,000 to US$600,000.

                                     I - 10

   13




         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 Registrant's loss of all or a portion of
its assets and business in Venezuela.

         Many aspects of the Registrant'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
Registrant 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 Registrant 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 Registrant, 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.

         OIL & GAS OPERATIONS

         The Registrant engages in the origination of prospects; the
identification, acquisition, exploration, and development of prospective and
proved oil and gas properties; the production and sale of crude oil, condensate,
and natural gas; and the marketing of natural gas. The Registrant considers
itself a medium-sized independent producer. All of the Registrant's oil and gas
operations are conducted in the United States.

         Most of the Registrant's current exploration and drilling effort is
concentrated in Oklahoma, Kansas, Texas, and Louisiana. The Registrant also
explores from time to time in New Mexico, Alabama, Michigan, Mississippi, and
the Rocky Mountain area.

         The Registrant's exploration and production division includes seven
geographical exploitation teams comprised of geological, engineering, and land
personnel. These personnel primarily develop in-house oil and gas prospects as
well as review outside prospects and acquisitions for their respective
geographical areas. The Registrant believes that this structure allows each team
to gain greater expertise in its respective geographical area and reduces risk
in the development of prospects.

         The Registrant continued its involvement in the Mountain Front play
during 1999, spending $10.2 million drilling and completing extensional and
development wells in both its Rocky and Kiowa Flats fields. In 1999, Registrant
drilled 13 wells, of which seven were completed as producing wells. Current
producing rates from the two fields are 63 MMCFD gross and 40 MMCFD net. The
Mountain Front area is located in Kiowa and Washita Counties, Oklahoma.

                                     I - 12

         During fiscal 1998 and 1999, the Registrant has focused on developing
prospects using 3D seismic technology. Currently, the Registrant is involved in
3D surveys covering more than 850 square miles. Approximately 700 square miles
of land covered by such surveys is located near the Texas and Louisiana onshore
Gulf Coast. This is Registrant's first major exploration effort in the Gulf
Coast area. The following summarizes the Registrant's activities, during fiscal
1999, on the lands covered by these 3D surveys.

         During fiscal 1999, the Registrant participated in or purchased three
3D seismic surveys covering approximately 185 square miles of lands in Jefferson
County, Texas. After successfully drilling four consecutive producing wells, the
Company extended these seismic surveys by approximately 42 square miles.
Registrant's working interests in the lands covered by this survey range from
54% to 66%. In addition, one well is currently being drilled in West Texas on
lands covered by a 65 square mile 3D survey.

         Four wells have been drilled in Galveston County, Texas, based upon a
94 square mile 3D survey. Two of the wells were completed as producers. This 3D
survey was extended by 27 square miles during the 1999 fiscal year. Registrant's
working interests in this area range from 25% to 87%.

         The Registrant recently completed the purchase of a 42% working
interest in a 50 square mile 3D survey in Calcasieu Parish, Louisiana. A wildcat
well is in the process of being completed. The purchase of a 35% working
interest in a 200 square mile 3D shoot in South Texas has also been finalized.
One wildcat well is currently being drilled on these lands.

         The Registrant's exploration and development program has covered a
range of prospects, from shallow "bread and butter" programs to deep expensive,
high

                                     I - 13

risk/high return wells. During fiscal 1999, the Registrant participated in 49
development and/or wildcat wells, which resulted in new discoveries of
approximately 22.5 BCF of gas and 151,829 barrels of oil and condensate. The
Registrant participated in five additional development wells, which resulted in
the development of approximately 1.2 BCF of gas which was previously classified
as proved undeveloped or proved developed nonproducing reserves. A total of
$36,613,104 was spent in the Registrant's exploration and development program
during fiscal 1999. This figure includes $8,216,501 of geophysical expense, but
is exclusive of expenditures for acreage and acquisition of proved oil and gas
reserves. The Registrant's total company-wide acquisition cost for acreage in
fiscal 1999 was approximately $14.4 million.

         The Registrant spent $88,997 for the acquisition of proved oil and gas
reserves during fiscal 1999. The reserves associated with these acquisitions
were 77,826 MCF.

         The Registrant's fiscal 2000 exploration and production budget of
approximately $80 million is 70% greater than its actual exploration and
production expenditures in fiscal 1999. This increase is necessary to exploit
the additional amounts of acreage acquired in fiscal years 1998 and 1999.

         Market for Oil and Gas

         The Registrant does not refine any of its production. The availability
of a ready market for such production depends upon a number of factors,
including the availability of other domestic production, price, crude oil
imports, the proximity and capacity of oil and gas pipelines, and general
fluctuations in supply and demand. The Registrant does not anticipate any
unusual difficulty in contracting to sell its

                                     I - 14

   17




production of crude oil and natural gas to purchasers and end-users at
prevailing market prices and under arrangements that are usual and customary in
the industry. The Registrant and its subsidiary, Helmerich & Payne Energy
Services, Inc., have successfully developed markets with end-users, local
distribution companies, and natural gas brokers for gas produced from successful
wildcat wells and development wells. The Registrant is of the opinion that the
natural gas market will continue to experience high volatility. This high
volatility (as evidenced by the mid-summer increase in natural gas prices, and
the subsequent price reductions during early November, 1999) is a result of ever
changing perceptions throughout the industry centered around supply and demand.
Pricing perceptions constantly change as members of the natural gas industry
weigh the impacts of decline in deliverability of domestic supply; increased use
of natural gas for electrical generation; continued U.S. economic growth;
increased usage and better management of natural gas storage; seasonal usage;
fuel switching; usage of gas as a feed stock; and importation of gas from Canada
and Mexico. Registrant presently believes that natural gas price volatility will
continue for the next three to five years as the natural gas industry reacts to
these factors. Long term pricing will obviously react to these short term
factors, as well as other considerations affecting supply/demand.

         Historically, the Registrant has had no long-term sales contracts for
its crude oil and condensate production. The Registrant continues its practice
of contracting for the sale of its Kansas and Oklahoma and portions of its west
Texas crude oil for terms of six to twelve months in an attempt to assure itself
of the best price in the area for crude oil production. During fiscal 1999, the
price that Registrant received

                                     I - 15

   18




for the sale of its crude oil has steadily increased. Registrant's average per
barrel crude oil sales price in fiscal 1999 for each of the first through fourth
quarters was $11.26, $11.21, $15.77 and $19.67, respectively.

         Competition

         The Registrant competes with numerous other companies and individuals
in the acquisition of oil and gas properties and the marketing of oil and gas.
The Registrant believes that it should continue to prepare for increased
exploration activity without committing to a definite drilling timetable. The
Registrant also believes that competition for the acquisition of gas producing
properties will continue. Considering the Registrant's conservative acquisition
strategy, the Registrant believes that it may be unable to acquire significant
proved developed producing reserves from third parties. The Registrant intends
to continue its review of properties in areas where the Registrant has
expertise. The Registrant's competitors include major oil companies, other
independent oil companies, and individuals. Many of these competitors have
financial resources, staffs, and facilities substantially larger than those of
the Registrant. The effect of these competitive factors on the Registrant cannot
be predicted.

         Title to Oil and Gas Properties

         The Registrant undertakes title examination and performs curative work
at the time properties are acquired. The Registrant believes that title to its
oil and gas properties is generally good and defensible in accordance with
standards acceptable in the industry.

         Oil and gas properties in general are subject to customary royalty
interests contracted for in connection with the acquisitions of title,

                                     I - 16

   19




liens incident to operating agreements, liens for current taxes, and other
burdens and minor encumbrances, easements, and restrictions. The Registrant
believes that the existence of such burdens will not materially detract from the
general value of its leasehold interests.

         Governmental Regulation in the Oil and Gas Industry

         The Registrant's domestic operations are affected from time to time
in varying degrees by political developments and federal and state laws and
regulations. In particular, oil and gas production operations and economics are
affected by price control, tax, and other laws relating to the petroleum
industry; by changes in such laws; and by constantly changing administrative
regulations. Most states in which the Registrant conducts or may conduct oil and
gas activities regulate the production and sale of oil and natural gas,
including regulation of the size of drilling and spacing units or proration
units, the density of wells which may be drilled, and the unitization or pooling
of oil and gas properties. In addition, state conservation laws establish
maximum rates of production from oil and natural gas wells, generally prohibit
the venting or flaring of natural gas, and impose certain requirements regarding
the ratability of production. The effect of these regulations is to limit the
amounts of oil and natural gas the Registrant can produce from its wells, and to
limit the number of wells or locations at which the Registrant can drill. In
addition, legislation affecting the natural gas and oil industry is under
constant review. Inasmuch as such laws and regulations are frequently expanded,
amended, or reinterpreted, the Registrant is unable to predict the future cost
or impact of complying with such regulations. The Registrant believes that
compliance with existing federal, state and local laws, rules and regulations
will not

                                     I - 17

   20




have a material adverse effect upon its capital expenditures, earnings or
competitive position.

         Regulatory Controls

         Historically, the transportation and sale for resale of natural gas in
interstate commerce have been regulated under the Natural Gas Act ("NGA") and
the Natural Gas Policy Act of 1978 ("NGPA") and the regulations promulgated
thereunder.

         The Natural Gas Wellhead Decontrol Act of 1989 amended both the price
and non-price decontrol provisions of the NGPA for the purpose of providing
complete decontrol of first sales of natural gas by January 1, 1993. The
Registrant believes that substantially all of its gas is decontrolled.

         Commencing in April, 1992, the Federal Energy Regulatory Commission
("FERC") issued Order 636, Order 636-A, and Order 636-B (collectively, "Order
636") which requires interstate pipelines to provide transportation unbundled
from their sales of gas. Also, such pipelines must provide open-access
transportation on a basis that is equal for all gas supplies. Although Order 636
has provided the Registrant with additional market access and more fairly
applied transportation service rates, it has also subjected the Registrant to
more restrictive pipeline imbalance tolerances and greater penalties for
violation of those tolerances. Order 636 and numerous related orders pertaining
to individual pipelines have been largely upheld by the Courts. However, certain
appeals remain pending, and the FERC continues to review and modify open access
regulations.

         In particular, the FERC recently issued new rules and policies
pertaining to interstate pipeline certificates which require notification

                                     I - 18

   21




of landowners affected by proposed pipeline construction, and which presume
incremental pricing is appropriate for new construction. The FERC also has
proposed rules governing short term transportation which, among other matters,
would eliminate cost-based regulation for such transportation, allow pipelines
to negotiate rates and terms of service, and require the allocation of all short
term pipeline capacity through a competitive auction process. In addition, the
FERC has requested comments on certain issues related to its regulation of long
term transportation. While any resulting FERC action would affect the Registrant
only indirectly, these inquiries are intended to further enhance competition in
the natural gas markets.

         Under the NGA, natural gas gathering facilities are exempt from FERC
jurisdiction. The Registrant believes that its gathering systems meet the
traditional tests that the FERC has used to establish a pipeline's status as a
gatherer. In recent years, the FERC has slightly narrowed its statutory tests
for establishing gathering status. A number of states have either enacted new
laws or are considering the adequacy of existing laws affecting gathering rates
and/or services. For example, in May, 1997, Kansas enacted new gathering
oversight legislation that, among other matters, requires reporting of gathering
prices and authorizes the Kansas Corporation Commission ("KCC") to oversee open
access on gathering systems to assure it is just, reasonable, and
non-discriminatory. Thus, natural gas gathering may receive greater regulatory
scrutiny by state agencies. In addition, the FERC has approved several transfers
by interstate pipelines of gathering facilities to unregulated gathering
companies, including affiliates. This could allow such companies to compete more
effectively with

                                     I - 19

   22




independent gatherers. It is not possible at this time to predict the ultimate
effect of the policy, although it could affect access to and rates charged for
interstate gathering services. However, the Registrant does not presently
believe the status of its facilities would be materially affected by
modification to the statutory criteria.

         In February, 1994, the KCC issued an order which modified allowables
applicable to wells within the Hugoton Gas Field so that those proration units
upon which infill wells had been drilled would be assigned a larger allowable
than those units without infill wells. As a consequence of this order, the
Registrant has drilled 137 infill wells and believes that it will be necessary
in fiscal 2000 to drill an additional 3 infill wells at a total estimated cost
of $360,000.

         In September, 1997, the FERC ruled that ad valorem tax levied by the
State of Kansas was not a severance tax within the meaning of Section 110 of the
NGPA. Therefore, to the extent that first sellers collected revenues in excess
of the maximum lawful price as a result of reimbursement of Kansas ad valorem
taxes, then first sellers would be required to make refunds with interest for
such excess revenues on tax bills rendered during the period October 4, 1983
through June 28, 1988. Based upon schedules provided to Registrant by certain
interstate pipelines, the total reimbursement obligation of all working interest
owners in Registrant-operated wells approximated $13 million as of November,
1997. During this period, Registrant estimated that its reimbursement obligation
totaled approximately $6.7 million, being approximately $2.7 million of
principal and $4.0 million of interest. Approximately 12.5% of such amount would
be owed by Registrant's royalty owners.

                                     I - 20

   23

         Neither the FERC nor Congress has provided the first sellers with any
generic relief on this issue. However, the FERC has permitted the filing of
individual adjustment proceedings by each first seller. Registrant has filed
such adjustment proceedings requesting that its ad valorem tax refund obligation
be reduced. The FERC has not ruled in any of Registrant's adjustment
proceedings.

         During the period February through July, 1998, Registrant paid, under
protest, approximately $1,379,000 to four interstate pipelines as partial ad
valorem tax reimbursement and escrowed approximately $6,370,000 pending the
FERC's decision in Registrant's adjustment proceedings. The escrowed amount
includes Registrant's share of the amount of reimbursement obligation allegedly
owed by Registrant's royalty owners. The final outcome of this matter cannot be
predicted at this time.

         Additional proposals and proceedings that might affect the oil and gas
industry are pending before the Congress, the FERC, and the courts. The
Registrant cannot predict when or whether any such proposals may become
effective. In the past, the natural gas industry has been very heavily
regulated. There is no assurance that the current regulatory approach pursued by
the FERC will continue. Notwithstanding the foregoing, it is anticipated that
compliance with existing federal, state and local laws, rules and regulations
will not have a material adverse effect upon the capital expenditures, earnings
or competitive position of the Registrant.

         Federal Income Taxation

         The Registrant's oil and gas operations, and the petroleum industry
in general, are affected by certain federal income tax laws.  The

                                     I - 21

   24




Registrant has considered the effects of such federal income tax laws on its
operations and does not anticipate that there will be any material impact on the
capital expenditures, earnings or competitive position of the Registrant.

         Environmental Laws

         The Registrant's activities are subject to existing federal and state
laws and regulations governing environmental quality and pollution control. Such
laws and regulations may substantially increase the costs of exploring,
developing, or producing oil and gas and may prevent or delay the commencement
or continuation of a given operation. In the opinion of the Registrant's
management, its operations substantially comply with applicable environmental
legislation and regulations. The Registrant believes that compliance with
existing federal, state, and local laws, rules, and regulations regulating the
discharge of materials into the environment or otherwise relating to the
protection of the environment will not have any material effect upon the capital
expenditures, earnings, or competitive position of the Registrant.

         Natural Gas Marketing

         Helmerich & Payne Energy Services, Inc., ("HPESI") continues into its
tenth year of business with emphasis on the purchase and marketing of the
Registrant's natural gas production. In addition, HPESI purchases third-party
gas for resale and provides compression, gathering services and processing for a
fee. During fiscal year 1999, HPESI's sales of third-party gas constituted
approximately 10% of the Registrant's consolidated revenues.

         HPESI sells natural gas to markets in the Midwest and Rocky Mountain
areas.  Term gas sales contracts are for varied periods ranging from

                                     I - 22

   25




three months to seven years. However, recent contracts have tended toward
shorter terms. The remainder of the Registrant's gas is sold under spot market
contracts having a duration of 30 days or less. For fiscal 2000, HPESI's term
gas sales contracts provide for the sale of approximately 16 BCF of gas at
prices which are indexed to market prices. HPESI presently intends to fulfill
such term sales contracts with a portion of the gas reserves purchased from the
Registrant as well as from its purchases of third-party gas. See pages I-14
through I-22 regarding the market, competition, and regulation of natural gas.

         REAL ESTATE OPERATIONS

         The Registrant's real estate operations are conducted exclusively
within the metropolitan area of Tulsa, Oklahoma. Its major holding is Utica
Square Shopping Center, consisting of fifteen separate buildings, with parking
and other common facilities covering an area of approximately 30 acres. Fourteen
of these buildings provide approximately 405,709 square feet of net leasable
retail sales and storage space (93% 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 Registrant's real estate operations. The fifteenth building is
an eight-story medical office building which provides approximately 76,379
square feet of net leasable medical office space (64% of which is currently
leased). The Registrant has a two-level parking garage located in the southwest
corner of Utica Square that can accommodate approximately 250 cars.

         Registrant has completed two phases of a three-phase renovation for
major existing tenants in Utica Square Shopping Center.  This renovation

                                     I - 23

   26




has resulted in a temporary occupancy reduction of approximately 4%. During
fiscal 2000, occupancy is expected to reach approximately 97%.

         At the end of the 1999 fiscal year the Registrant owned 12 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 condominium units were sold
during fiscal 1999. Twelve of the Registrant's units are currently leased.

         The Registrant 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 and retail space. This
building houses the Registrant's principal executive offices. Approximately 11%
of this building was leased to third parties during fiscal 1999. Registrant has
leased approximately 29,000 square feet of office space in Tulsa and relocated
Registrant's oil and gas division from Registrant's office building to such
leased office space. The vacated space within Registrant's office building has
been used to accommodate the growth of the remaining segments of its businesses.

         The Registrant is also engaged in the business of leasing 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 Registrant also owns approximately 1.5
acres of undeveloped land lying adjacent to such warehouses.

                                     I - 24

   27




         Registrant owns approximately 253.5 acres in Southpark consisting of
approximately 240.5 acres of undeveloped real estate 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. Occupancy has
decreased from 100% to 96% due to the loss of one tenant. The Registrant
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.

         The Registrant 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 96% to 93% during
fiscal 1999 due primarily to the loss of one tenant. The Registrant 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 1999, occupancy has remained at 96%.

         The Registrant 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 1999, occupancy has
remained at 100%. The second, called Maxim Place, consists of one
office/warehouse building containing

                                     I - 25

   28




approximately 33,750 square feet and located on approximately 2.25 acres. During
fiscal 1999, occupancy has remained at 100%.

         Registrant believes that the recent increase in demand for multi-tenant
warehouse space in the Tulsa market will continue. Registrant is unable to
determine how long this increase in demand will continue.

         Competition.

         The Registrant 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.
Registrant'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 Registrant and have more
contemporary facilities.

         Acreage is held under leases which expire in the absence of production
at the end of a prescribed primary term, and is, therefore, subject to
fluctuation from year to year as new leases are acquired, old leases expire, and
other leases are allowed to terminate by failure to pay annual delay rentals. As
shown in the above table, the Registrant has a significant portion of its
undeveloped acreage in Texas, with five major prospects accounting for 39,700
net acres. The average minimum remaining term of leases in these five prospects
is approximately 30 months.
