ITEM 1.  BUSINESS

GENERAL - ONEOK Inc., a Delaware corporation, was organized in 1936.  It is a
successor to a company founded in 1906 as Oklahoma Natural Gas Company.  The
corporation's name was changed to ONEOK Inc. (pronounced one-oak) in 1981.
ONEOK Inc. and subsidiaries (collectively, the Company) is a diversified energy
company engaged in the production, gathering, storage, transportation,
distribution and marketing of environmentally clean fuels and products.  The
Company's business units are characterized as operating within either a rate
regulated environment (regulated operations) or a nonregulated environment
(nonregulated operations).

The regulated business unit provides natural gas distribution and transmission
for about 75 percent of Oklahoma.  These services are primarily conducted by
Oklahoma Natural Gas Company (a division of ONEOK) and three subsidiaries, ONG
Gathering Company, ONG Transmission Company and ONG Sayre Storage Company.
These companies will be collectively referred to herein as Oklahoma Natural
Gas.

The nonregulated business unit includes the following core business segments:
natural gas marketing activities conducted by ONEOK Gas Marketing Company; gas
processing activities conducted primarily by ONEOK Products Company; and
production activities conducted by ONEOK Resources Company and ONEOK
Exploration Company.  Other businesses include ONEOK Leasing Company; ONEOK
Parking Company; and Fifth Street Investment Corporation.

ENVIRONMENTAL MATTERS - The Company is subject to Federal, state, and local
laws and regulatory programs relating to the environment.  These laws govern
the normal ongoing operations of the Company including the discharge of
materials into the environment or the protection of the environment.  Ongoing
environmental compliance activities are integrated with the Company's regular
operation and maintenance activities.  The Company is actively promoting the
environmental advantages of natural gas in comparison to other fuels including
promoting the use of natural gas in automobiles.  Management believes that the
increasing concerns about the environment will result in an increased use of
natural gas.

There have been no material effects upon capital expenditures, earnings, or the
Company's competitive position during the 1996 fiscal year related to
compliance with these regulations.  No material effects of this nature are
anticipated during the 1997 fiscal year.

EMPLOYEES - The Company employed 1,884 persons at August 31, 1996, and is
currently not a party to any collective bargaining agreements with such
employees.

FINANCIAL AND STATISTICAL INFORMATION  - For financial and statistical
information regarding the Company's business units by segment, see "
Management's Discussion and Analysis of Financial Condition and Results of
Operations" and Note I of Notes to Consolidated Financial Statements.

The Company's regulated and nonregulated business units are discussed below.

(A)  REGULATED OPERATIONS

     GENERAL

     Oklahoma Natural Gas Company and three regulated subsidiaries of ONEOK
     comprise a fully integrated intrastate natural gas gathering, storage,
     distribution and transmission business, which purchases, stores,
     transports, and distributes natural gas for sale to wholesale and retail
     customers located primarily in the state of Oklahoma. It also leases
     pipeline capacity to industrial customers for their use in transporting
     natural gas to their facilities. ONG Transmission Company transports gas
     for others under Section 311(a) of the Natural Gas Policy Act of 1978
     (NGPA). Oklahoma




                                       3
<PAGE>   4


     Natural Gas Company, ONG Transmission Company, ONG Sayre Storage Company
     (Sayre), and ONG Gas Gathering Company are consolidated for ratemaking
     purposes by the Oklahoma Corporation Commission (OCC).

     Oklahoma Natural Gas purchases natural gas from gas processing plants,
     producing gas wells, and pipeline suppliers, and utilizes five underground
     storage facilities as necessary to deliver natural gas to approximately
     729,500 customers at August 31, 1996, located in 294 communities in
     Oklahoma. The Company's largest markets are the Oklahoma City and Tulsa
     metropolitan areas. Oklahoma Natural Gas also sells natural gas and/or
     leases pipeline capacity to other local gas distributors serving 44
     Oklahoma communities. Oklahoma Natural Gas serves an estimated population
     of over 2 million.

     Oklahoma Natural Gas owns five underground gas storage facilities and
     leases capacity to third parties on a short-term basis. The Sayre gas
     storage facility is leased, on a long-term basis, to and operated by the
     Natural Gas Pipeline Company of America. Sayre retains capacity for its
     use.

     Of the Company's consolidated revenues, revenue from the regulated
     operations represented approximately 44.0, 62.3, and 78.6 percent for
     1996, 1995, and 1994, respectively. Operating income before interest and
     taxes from the regulated operations is 80.4, 86.8, and 95.4 percent of the
     consolidated operating income before interest and taxes for 1996, 1995,
     and 1994, respectively.

     The Company is interested in acquiring gas distribution and transmission
     facilities which will enhance its operations and continues to pursue
     opportunities for acquisitions as they occur.

     GAS SUPPLY

     Gas supplies available to Oklahoma Natural Gas for purchase and resale or
     transportation include supplies of gas under both short and long-term
     contracts with independent producers as well as pipeline companies, gas
     processors and other suppliers that own or control reserves. Oklahoma is
     the third largest gas producing state in the nation; and Oklahoma Natural
     Gas, unlike most utilities, has direct access through its transmission
     system to all of the major gas producing areas in the state. The system,
     which intersects with nine interstate pipelines at 25 interconnect points,
     38 gas processing plants and 129 producing fields located in Oklahoma
     allows natural gas to be moved to locations throughout the state and the
     nation. In addition, four of the storage facilities operated by Oklahoma
     Natural Gas are located in close proximity to its large market areas.
     These four storages have a combined average capacity of 119 billion cubic
     feet to help assure deliverability to customers even on winter peak usage
     days. On such days, withdrawal from storage can provide as much as 50
     percent of the system's needs A new record for all-time peak gas
     deliveries through the system in a single day of 1.92 billion cubic feet
     was set on February 2, 1996.

     The Oklahoma Natural Gas rate schedules contain an "Order of Curtailment"
     that provides for first reducing or totally discontinuing gas service to
     the very large industrial users and graduating down to requesting
     residential and commercial customers to reduce their gas requirements to
     an amount essential for public health and safety.

     The Company has a surplus of natural gas available to its utility system
     and does not anticipate any problem with securing additional gas supply as
     needed for its customers for the foreseeable future.

     CUSTOMERS

     RESIDENTIAL AND COMMERCIAL - Oklahoma Natural Gas distributes natural gas
     as a public utility to approximately 75 percent of Oklahoma. Natural gas
     sales to residential and commercial customers, which is used primarily for
     heating and cooking, accounts for approximately 56 and 29 percent of gas
     sales, respectively. Gas sales to residential and commercial customers are
     seasonal, as a substantial portion of such sales are used principally for
     space heating. Accordingly, the volume of gas sales is consistently higher
     during the heating season (November through May) than in other months of
     the year. Rates for natural gas distribution operations include a
     temperature normalization adjustment clause.




                                       4
<PAGE>   5


     Oklahoma Natural Gas holds franchises, all of which are for an initial
     period of 25 years, in the major municipalities in which it operates. In
     the state of Oklahoma, a franchise is a right to use the municipal
     streets, alleys, and other public ways for utility facilities for a
     defined period of time for a fee. Although the laws of the state of
     Oklahoma prohibit exclusive utility franchises, management nevertheless
     believes there are advantages to having franchises in the larger
     municipalities in which operations are conducted. Seventeen municipalities
     with a population of over 10,000 in which franchises are held, have an
     aggregate population representing approximately 1.2 million. Oklahoma
     Natural Gas has franchises or gross receipts agreements in 42 other
     municipalities in which there is an aggregate population of approximately
     102,000. In management's opinion, its franchises contain no unduly
     burdensome restrictions and are sufficient for the transaction of business
     in the manner in which it is now conducted.

     INDUSTRIAL - A substantial portion of the gas delivered through the
     pipeline system is delivered to industrial customers, in particular,
     several large fertilizer plants which use the gas as feed stock. In the
     past, certain interstate and intrastate pipeline companies have been very
     aggressive in attempting to capture industrial load within the Oklahoma
     Natural Gas service area, a phenomenon generally referred to in the gas
     industry as "bypass". Oklahoma Natural Gas has minimized the negative
     impact of bypass practices through its Pipeline Capacity Lease (PCL) and
     Special Industrial Sales (SISP) Programs. The PCL program enables the
     customer, for a fee, to have its gas transported to its facilities
     utilizing lines owned by Oklahoma Natural Gas. PCL services are at rates
     substantially below the industrial tariff rates. In 1995, the OCC allowed
     rates for large industrial customers to be restructured and reduced. Under
     this new structure, tariffs are established setting forth the maximum rates
     and a standard form of PCL agreement, subject to changes in the agreement
     as may be negotiated by Oklahoma Natural Gas and the customer. The SISP
     program allocates lower cost supplies to these customers if they choose to
     purchase their gas from Oklahoma Natural Gas.

     Industrial sales, rentals for PCLs, and other energy-related operations
     tend to remain relatively constant throughout the year, while interstate
     transportation volumes fluctuate based on market demand. Revenues from
     fertilizer plant customers continue to decline as a percentage of total
     revenues as a result of the rate restructuring noted at "Government
     Regulations". Currently, all the fertilizer plants are operating at or
     near full capacity. No single customer accounted for more than 10 percent
     of the Company's total operating revenues.

     The potential impact of the loss of a significant portion of this volume
     is discussed at Management's Discussion and Analysis of Financial
     Condition and Results of Operations, Liquidity, on page 23.

     COMPETITION

     The natural gas industry is expected to remain highly competitive with
     respect to both gas supply and markets. Management believes that it must
     maintain a competitive advantage in order to retain its customers and,
     accordingly, continues to focus on reducing costs and pursuing unbundling
     opportunities. Strategic planning has identified several potential new
     service opportunities. Such services could include equipment service
     contracts, operating services, gas marketing and supply management, gas
     storage for others, gas measurement services and gas transportation.

     Oklahoma Natural Gas is subject to competition from electric utilities,
     offering electricity as a rival energy source, competing for the space
     heating, water heating, and cooking markets. The principal means to
     compete against alternative fuels is lower prices, and natural gas
     continues to maintain its price advantage in the residential, commercial,
     and both small and large industrial markets. Compared to electricity for
     water heating, cooking or home heating, natural gas service provided by
     Oklahoma Natural Gas is 57 percent, 53 percent and 71 percent less
     expensive. Oklahoma Natural Gas rates are competitive nationally. In
     residential markets, the average cost of 10 Mcf is $51.41 for Oklahoma
     Natural Gas customers versus $58.01 for the average cost in 31 cities
     nationwide.

     Oklahoma Natural Gas is subject to competition from other pipelines for
     its existing industrial load. The PCL program and SISP programs are a
     response to such competitive pressure. The new PCL




                                       5
<PAGE>   6


     rate structure approved in June 1995 allows Oklahoma Natural Gas to
     effectively compete in these markets and maintain throughput and therefore
     load factors which benefit all customer classes.

     In April 1992, the Federal Energy Regulatory Commission (FERC) approved
     Order 636. Less than one percent of Oklahoma Natural Gas's gas supply is
     transported on interstate pipelines; Order 636 has had little impact on
     its operations.

     GOVERNMENT REGULATIONS

     Rates charged for gas services, including distribution, transmission and
     storage, are established by the OCC and include a purchased gas adjustment
     clause that allows changes in gas purchase costs to be passed on to
     various classes of customers. Other costs must be recovered through
     periodic rate adjustments approved by the OCC.

     In the past, the Company experienced claims and potential liabilities
     arising out of long-term gas supply contracts containing "take-or-pay"
     provisions which purported to require the Company to pay for volumes of
     natural gas contracted for but not taken. There are no significant
     potential claims or cases pending against the Company under remaining gas
     purchase contracts. In a 1994 rate order, the OCC authorized an annual
     recovery of $6.7 million of the accumulated settlement costs by a
     combination of a surcharge from customers and revenue from transportation
     under Section 311(a) of the NGPA and other intrastate transportation
     revenues.

     On June 19, 1995, the OCC approved a settlement of all issues in a pending
     rate proceeding. Under the settlement, Oklahoma Natural Gas received a
     $13.8 million permanent increase in base rates and an additional $1.15
     million increase for two years. Rates for large industrial customers were
     restructured and reduced, with the revenue reduction shifted to core
     residential and commercial customers. Changes to purchasing and pricing
     practices provided a decrease in the cost of gas that more than offset the
     impact of the rate increase, allowing core customers a net savings in
     rates. The order also included a temperature adjustment clause, an
     agreement not to file for a general rate increase for two years, and
     amortization of the additional deferred pension costs not covered by prior
     orders.

     OTHER REGULATED BUSINESSES

     Through its subsidiary, TransTex Pipeline Company (TransTex), the Company
     owned a 25 percent limited partnership interest in Red River Pipeline (Red
     River). Effective January 1, 1996, TransTex withdrew as a limited partner
     and received as a distribution a portion of the assets of the partnership.
     Such assets, which are regulated by the Railroad Commission of Texas, were
     then leased back to Red River under a long term lease.

     OkTex Pipeline Company transports gas in interstate commerce under Section
     311(a) of the NGPA and is treated as a separate entity by the Federal
     Energy Regulatory Commission (FERC). The Company has the capacity to move
     up to 200 million cubic feet of gas per day into Lone Star Gas Company's
     system in Texas and the Red River Pipeline. OkTex has complied with the
     requirements of Order 636.

(B)  NONREGULATED OPERATIONS

     MARKETING

     GENERAL - The Company's marketing operation purchases and markets natural
     gas, primarily in the mid-continent area of the United States. Although
     formed in 1992, marketing did not have significant operations until 1995.
     Due to expanded supply and storage capabilities the marketing operation
     grew from an intrastate aggregator into a interstate aggregator with an
     average daily sales volume of 868,401 MMbtu, 705,406 MMbtu, and 475,853
     MMbtu in 1996, 1995, and 1994, respectively.




                                       6
<PAGE>   7


     Of the Company's consolidated operating revenues, revenue from the gas
     marketing business represented approximately 48.9, 27.9, and 10.0 percent
     for 1996, 1995, and 1994, respectively. Operating income before interest
     and taxes from the marketing operation is 10.7, 4.5 and 4.1 percent of the
     consolidated operating income before interest and taxes for 1996, 1995,
     and 1994, respectively.

     MARKET CONDITIONS - The marketing business is very competitive and, as the
     industry matures, continues to go through a period of consolidation and
     reduced margins. Management expects that mega-marketers (entities which
     market over 5 Bcf per day) will dominate the industry. The Company's
     strategy is to concentrate on margins and not compete on the basis of
     volumes. Management believes that its location in Oklahoma, as well as the
     benefits derived from vertically integrating the gas marketing operations
     with the Company's production, gathering, processing, storage and
     transportation businesses, will provide the strategic advantage necessary
     to compete.

     NEW PRODUCTS AND SERVICES - Gas marketing is a low margin business that
     experiences extreme volatility and can be expensive for small producers to
     manage. Management believes that there are a significant number of such
     producers in Oklahoma. Accordingly, the Company will introduce ONEOK
     Producer Services, an entity which will specialize in servicing this niche
     market. ONEOK Producer Services will focus on aggregating and providing
     producer services under medium-term agreements. Service will be packaged
     to meet each producer's needs, such as investigating options for new well
     pipeline connections, facilitating connections, keeping production
     balanced to nominated volumes and handling certain administrative
     accounting functions.

     The Company has filed an application with FERC to market electricity.
     Management anticipates that permits will be granted during the first
     quarter of 1997. It is not anticipated that such activities will be a
     major contributor to earnings in 1997.

     PRICE RISK MANAGEMENT - In order to mitigate the financial risks arising
     from fluctuations in both the market price and transportation costs of
     natural gas, the Company routinely enters into natural gas futures, swaps
     and options as a method of protecting its margins on the underlying
     physical transactions. However, net open positions in terms of price,
     volume and specified delivery point do occur.

     PROCESSING

     GENERAL - The Company's processing operation owns nonoperating interests
     in 15 gas processing plants. Currently, 12 plants are in operation and are
     running near or at capacity. The gas processing operations include the
     extraction of natural gas liquids (NGLs) and the separation
     ("fractionation") of mixed NGLs into component products (eg., ethane,
     butane, propane, isobutane). Such liquids are used as a petrochemical
     feedstock, for residential heating and cooking in rural areas, and blended
     into motor fuels. The industry as a whole operates substantial numbers of
     such plants, many owned by large integrated oil and gas companies and
     independents. NGL margins have been highly volatile over the past several
     years as profitability is dependent on the relationship between natural
     gas costs and NGL prices. Management believes that the industry is
     becoming much more competitive as demand increases for NGLs, especially
     petrochemical feedstock.

     Extraction is the process of removing NGLs from the gas stream, thereby
     reducing the Btu content and volume of incoming gas (referred to as
     "shrinkage"). In addition, some gas from the gas stream is consumed as
     fuel during the processing. The production costs of such liquids generally
     depend on the cost of the natural gas being processed and the underlying
     agreements. The Company compensates its gas suppliers for fuel and
     shrinkage costs in one of two ways, either by returning a percentage of
     the proceeds from the extracted NGLs to the supplier (a "percent of
     proceeds" contract) or by replacing an equivalent amount of gas (a "fuel
     and shrink" contract). Due to the volatility of the natural gas and NGL
     prices, "percent of proceeds" contracts generally provide a more stable
     cash flow. At August 31, 1996, the Company's processing plants are
     operating with 70 percent "fuel and shrink" and 30 percent "percent of
     proceeds" contracts.

     Of the Company's consolidated operating revenues, revenue from the gas
     processing business represented approximately 4.8, 6.8, and 8.3 percent
     for 1996, 1995, and 1994, respectively. Operating income before interest
     and taxes for the processing operation is 7.4, 6.0, and 3.7 percent of the
     consolidated operating income before interest and taxes for 1996, 1995,
     and 1994, respectively.

     PROCESSING CAPABILITIES - Recent developments include the expansion of
     plant gathering systems into new areas of production, the development of
     producer alliances and bringing plants to capacity. Future strategies
     include the relocation of under-utilized processing plants to new
     production areas, the expansion of existing capabilities and growth
     through acquisition of additional plants and gathering systems.

     Because of the generally favorable location of the plants and terms of the
     Company's processing and operating agreements, management anticipates
     continuing to have favorable fuel costs and anticipates that its currently
     competitive position in processing will remain so for the near future.

     PRODUCTION

     GENERAL - The Company's production operation strategy is to concentrate
     ownership of hydrocarbon reserves in Oklahoma in order to add value not
     only to its existing production operations but also to integrate the
     processing, marketing, transmission and storage businesses. As a result,
     the Company intends to focus its efforts on exploitation activities.
     Effective September 1, 1996, the Company merged ONEOK Exploration Company
     into ONEOK Resources Company.

     Of the Company's consolidated operating revenues, revenue from the
     production business represented approximately 2.1, 2.5, and 2.9 percent
     for 1996, 1995, and 1994, respectively. Operating income before interest
     and taxes for the production operation is 2.3, 3.4, and 0.8 percent of the
     consolidated operating income before interest and taxes for 1996, 1995,
     and 1994, respectively.

     PRODUCING RESERVES - Natural gas is the primary focus of the Company's
     production activities. As of August 31, 1996, the Company had working
     interests in 821 gas wells and 237 oil wells located primarily in Oklahoma
     and Louisiana. The Company acts as operator on 234 of these properties. A
     number of these wells are multiple completions.

     During 1996, the Company purchased substantially all of the Oklahoma oil
     and natural gas properties of SCANA Petroleum Resources. The $43.1 million
     purchase included over 500 producing properties of which 90 percent are
     natural gas. Also in 1996, the Company sold all of its oil and gas
     producing properties in Alabama and Mississippi for approximately $18.9
     million.

     MARKET CONDITIONS - The goal of the Company is to develop an economical
     reserve base through acquisition and development. Additionally, the
     Company plans to become more active as an operator. In doing so, the
     Company competes with many large integrated oil and gas companies and
     numerous independent oil and gas companies of various sizes. The Company,
     like the rest of the industry, has occasionally curtailed some of its
     natural gas production because of low prices. Most production is sold to
     brokers at spot-market prices. The Company has expanded its hedging of gas
     production using swaps and futures contracts.

     OTHER BUSINESSES

     The Company, through two subsidiaries, owns a parking garage and leases an
     office building (ONEOK Plaza) in downtown Tulsa, Oklahoma in which the
     Company's headquarters is located. The parking garage is owned and
     operated by ONEOK Parking Company. ONEOK Leasing Company leases excess
     office space to others. The downtown Tulsa office leasing market continues
     to have excess capacity. Rates remain relatively flat while the excess
     capacity is being absorbed by the market.

<PAGE>   9


     On August 18, 1995, the Company, through a subsidiary, Fifth Street
     Investment Corporation, submitted a written offer to Midtown Associates,
     the general partner of Southwestern Associates (the "Partnership"), the
     owner of the office building, to acquire the Partnership's equity in the
     building, subject to existing indebtedness. The offer was rejected. On
     October 7, 1995, offers were made to purchase the interests of limited
     partners in the Partnership at a price of $102,000 per unit for up to 33
     aggregate units. In addition, an offer was made to the limited partners
     guaranteeing at least $92,000 per unit when the building sells or the
     Partnership dissolves in return for proxies to vote the interests of the
     limited partners in the Partnership. The proxy offer was open to holders
     of the first 45 aggregate units (including up to 33 aggregate units for
     which the offers to purchase are accepted). The Company failed to receive
     a sufficient amount of acceptances and withdrew its offer.

ITEM 2.  PROPERTIES

(A)  DESCRIPTION OF PROPERTY

     REGULATED

     DISTRIBUTION - Oklahoma Natural Gas owned 14,680 miles of pipeline and
     other distribution facilities in Oklahoma at August 31, 1996. Oklahoma
     Natural Gas Company owns a five-story office building in Oklahoma City,
     Oklahoma, as well as a number of warehouses, garages, meter and regulator
     houses, service buildings, and other buildings throughout the state.
     Oklahoma Natural Gas Company also owns a fleet of vehicles and maintains
     an inventory of spare parts, equipment, and supplies. In addition,
     Oklahoma Natural Gas owns five underground storage facilities located
     throughout the state. Four of the storage facilities operated by Oklahoma
     Natural Gas are located in close proximity to its large market areas.
     These four storages have a combined storage capacity of 124.5 billion
     cubic feet. The other storage facility is located in western Oklahoma and
     is leased to and operated by another company. However, 21.5 billion cubic
     feet of storage capacity in this facility have been retained for use by
     Oklahoma Natural Gas.

     TRANSMISSION - Oklahoma Natural Gas owned a combined total of 3,840 miles
     of transmission and gathering pipeline in Oklahoma at August 31, 1996.
     Compression and dehydration facilities are located at various points
     throughout the pipeline system.

     Through a subsidiary, the Company leases 57.89 miles of transmission
     pipeline in Texas to the Red River Pipeline.

     PRODUCTION

     The Company owns varying economic interests, including overriding royalty
     interests, in 821 gas wells and 237 oil wells, some of which are multiple
     completions. Such interests are in wells located primarily in Louisiana
     and Oklahoma. The Company owns 73,227 net onshore developed leasehold
     acres and 14,014 net onshore undeveloped acres, located primarily in
     Louisiana, Oklahoma, and Texas. The Company owns no offshore acreage.

     Lease acreage in producing units is held by production. Leases not being
     held by production are generally for a term of three years and require
     payments of annual rentals.

     PROCESSING

     The Company owns interests in 15 gas processing plants which extract
     liquid hydrocarbons from natural gas. All are located in Oklahoma. The
     Company's share of the capacity of the plants totals 334 million cubic
     feet per day.

     OTHER

     The Company owns a parking garage with 1,179 parking spaces and land,
     subject to a long-term ground lease expiring in year 2009 with six
     five-year extensions available, upon which has been constructed a
     seventeen-story office building with approximately 517,000 square feet of
     net rentable space. The office building is being leased to the Company at
     a lease term of 25 years with six five-year renewal options. After any
     renewal period, the Company can purchase the property at its fair market
     value. The Company has occupied and reserved approximately 260,000 square
     feet of space for its own use and leases the remaining space to others.

(B)  OTHER INFORMATION

     Production figures are defined by the Securities and Exchange Commission
     (SEC) to include natural gas liquids from Company-owned leases. The
     Company produces a substantial amount of natural gas liquids as a result
     of ownership in several gas processing plants, but the Company does not
     own the reserves attributable to the leases producing the gas processed by
     these plants. As a result of this exclusion by the SEC, information
     concerning these natural gas liquids is not included in any of the tables
     in this section.

     OIL AND GAS RESERVES

     All of the oil and gas reserves are located in the United States.

ITEM 3. LEGAL PROCEEDINGS

FENT, ET UX V. OKLAHOMA NATURAL GAS COMPANY, A DIVISION OF ONEOK INC., ET AL.,
No. CJ-88-10148, District Court, Oklahoma County ("Fent I case"). On October 6,
1988, the Plaintiffs filed a petition for reimbursement for the cost of
replacement of a yard line and for repairing the gap in piping caused by the
relocation of the meter to the property line and as a class action for
similarly situated customers. The company moved to dismiss the action on the
grounds the District Court did not have subject matter jurisdiction and a
failure to state a cause of action for which relief could be granted. The
District Court granted the motion to dismiss and the Plaintiffs appealed the
decision. On August 14, 1991, the Court of Appeals reversed the trial court's
decision and remanded the case for further proceedings. The appellate court
held that the trial court had erred in ruling both that it was without
jurisdiction and that the Plaintiffs had failed to state a cause of action,
instead finding that under Commission Rule 6(a) the Company could be
responsible for maintenance of the gas line up to the outflow side of the
meter. As a result, the Company could have a duty to repair the gap caused by
removal of the meter and to maintain and repair the yard line. The case was
remanded to the District Court, the Company filed a related proceeding with the
Oklahoma Corporation Commission seeking an interpretation of the applicable
Commission rules, and although the Plaintiffs filed a motion in district court
to certify the class, further proceedings in the case were stayed pending
resolution of the appeal of the decision in the related Corporation Commission
proceeding. The Corporation Commission proceeding was resolved. Plaintiffs
filed a motion to lift the stay which was granted by the Court, enabling the
case to proceed with discovery on the issue of whether claims should be
certified as a class action and plaintiff's allowed to act as class
representatives. The Company filed a motion to strike on the basis of the
Oklahoma Corporation Commission decision in Fent III (see below) that the
Company was not responsible for non-Fent yardlines, which was granted on July
26, 1996. Fent has appealed the ruling to the Oklahoma Supreme Court.

APPLICATION OF OKLAHOMA NATURAL GAS COMPANY, A DIVISION OF ONEOK INC. FOR A
DETERMINATION THAT UNDER THE COMMISSION'S EXISTING NATURAL GAS UTILITY RULES
AND REGULATIONS, AND OKLAHOMA NATURAL'S EXISTING SERVICE RULES AND REGULATIONS,
THE GAS UTILITY CUSTOMERS OF OKLAHOMA NATURAL GAS COMPANY, EXCEPT JERRY R. FENT
AND MARGARET B. FENT, ARE RESPONSIBLE FOR INSTALLING AND MAINTAINING ALL PIPING
BETWEEN THE CUSTOMERS' PROPERTY OR CURB LINES, AND SUCH CUSTOMERS' POINTS OF
CONSUMPTION OF GAS, Cause PUD No. 95000223, Oklahoma Corporation Commission
("Fent III" Case). [On February 24, 1992, in Cause PUD No. 001123 (hereinafter
referred to as the "Fent II" case), the Commission issued Order No. 363449,
holding that under the Commission Gas Rules and ONG Rules, a gas utility
customer is financially responsible for the installation, maintenance, repair
or replacement of the customer's yard line, being the line lying between the
gas utility's main located at the property or curb line, or easement, and the
premises being served, and lying outside of any easement, regardless of where
the gas meter is located. The Commission's Order in Fent II was subsequently
appealed to the Oklahoma Supreme Court, which issued an opinion in Fent v.
Oklahoma Natural Gas Co., 898 P.2d 126 (1994), resulting in a reversal of the
Commission's Order. In its opinion the Supreme Court stated that its
pronouncement did not question the general power of the Commission to regulate
utilities by rulemaking and to interpret its own rules; it was addressed
narrowly to the agency's attempt to affect the Fent's pending district court
claim. However, the Court reversed the Commission's Order in its entirety.] On
September 27, 1995, the Company filed an application requesting that the
Commission reaffirm its order in Fent II as it applies to ratepayers other than
the Fents, for application in the Fent I case if it should be certified as a
class action. On November 29,1995, Fent filed for a Writ of Prohibition with
the Oklahoma Supreme Court which was denied on March 6, 1996. A hearing on the
Company's application was held April 10, 1996 and an Order issued April 24,
1996 granting the Company's application. The Fents and Harold Jenks (another
customer of the Company) have appealed the Order to the Oklahoma Supreme Court.
The Company filed a response to the appeal and a motion to dismiss the Fent's
appeal for lack of standing and their appeal was dismissed on September 23,
1996. The Jenks appeal is still pending.

UNITED STATES EX REL. JACK J. GRYNBERG V. ALASKA PIPELINE COMPANY, ET AL.
(INCLUDING ONEOK INC.), No. 95-725-TFH, in the United States District Court for
the District of Columbia. This is a qui tam action brought by the plaintiff on
behalf of the United States pursuant to the False Claims Act, 31 U.S.C. Section
3729, et seq., to recover the underpayment of royalties on federally owned or
Indian properties from 70 named pipeline companies, including ONEOK Inc. The
plaintiff claims that the 70 named pipeline companies have underpaid royalties
to the United States as a result of the improper measurement of the heating
content and volume of natural gas which they purchased from the federally owned
or Indian lands. On behalf of the United States, the plaintiff seeks to recover
the proceeds for the underpayment of royalties, interest, treble damages, civil
penalties of $5,000 to $10,000 for each violation by a defendant pipeline
company of the False Claims Act, and an order requiring the defendant pipeline
companies to discontinue the improper practices. The plaintiff also seeks to
recover his expenses incurred in bringing the action, plus attorneys' fees and
costs. All answers and responses to the Second Amended Complaint are due by
November 13, 1996.

IN THE MATTER OF COMMISSIONER BOB ANTHONY'S INSPECTION OF THE BOOKS AND RECORDS
OF ANY PUBLIC SERVICE CORPORATION AND EXAMINATION, UNDER OATH, ANY OFFICER,
AGENT, OR EMPLOYEE OF SUCH, IN RELATION TO THE BUSINESS AND AFFAIRS OF ARKANSAS
LOUISIANA GAS COMPANY, A DIVISION OF NORAM ENERGY CORP. AND OKLAHOMA NATURAL
GAS COMPANY, A DIVISION OF ONEOK INC. PURSUANT TO OKLAHOMA CONSTITUTION ARTICLE
9, SECTIONS 18, 28 AND 34, Cause No. PUD 960000039 and related dockets (PUD
96-85, 96-100, 96-186) Oklahoma Corporation Commission. Commissioner Anthony
filed notice on February 13, 1996, and thereafter sought, in his capacity as an
individual Commissioner, to investigate transactions between the Company and
other entities in connection with the 1993 settlement of a long-running gas
contract dispute between the Company and one of its gas suppliers, Creek
Systems. The principal subject of the inquiry was a new gas supply arrangement
entered into in connection with the settlement between the Company and an
entity called Dynamic Energy Resources, which in turn assigned its interest in
the contract to two other unrelated companies. Commissioner Anthony contended
that he was questioning whether the new gas supply arrangement entered into as
a result of the settlement had resulted in excessive gas costs to the Company's
customers. The gas supply contracts in question had been examined in earlier
audits by the Commission staff and no improper costs or other improprieties had
been found. After extensive Commission proceedings and an original action in
the Oklahoma Supreme Court challenging Anthony's authority to conduct such an
individual investigation, a compromise was reached among all interested parties
(other than Commissioner Anthony) pursuant to which another Commission staff
investigation of the matter was conducted with full cooperation by the Company.
The investigation has been completed and a report on the results is currently
being compiled by the Staff.

The Company is a party to other litigation matters and claims which are normal
in the course of its operations, and while the results of litigation and claims
cannot be predicted with certainty, management believes the final outcome of
such matters will not have a materially adverse effect on consolidated results
of operations, or financial position, or liquidity.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS

OPERATING ENVIRONMENT AND OUTLOOK

Each of the Company's business units has taken steps over the past two years to
strengthen its competitive edge and position it to be a leader in the industry.
The highlights for these units include:

o    REGULATED OPERATIONS - Changes initiated by Oklahoma Natural Gas in 1995
     allowed rates to be restructured for large industrial customers,
     positioning the Company to more effectively compete for additional
     customers. In addition, the OCC approved a request for a temperature
     adjustment clause that normalizes the effect of weather during the heating
     season, the first such program approved in Oklahoma.

o    NONREGULATED OPERATIONS - ONEOK Gas Marketing experienced significant
     growth in the last year becoming a billion cubic foot per day marketing
     operation. The processing segment owns seven percent of the state's
     processing capacity. Gathering systems around six plants were expanded to
     bring them to operating capacity during the current year. The production
     segment has significantly reduced its exploration activities; rather it
     concentrates on exploitation activities and reserve ownership in Oklahoma.
     Currently, 89 percent of the Company's reserves are located in Oklahoma,
     up from 53 percent one year ago.

In the opinion of management, a significant indicator of future changes to be
encountered by the Company came in the form of a notice of inquiry (NOI)
regarding the restructuring of Oklahoma's gas utility industry issued by the
OCC in the spring of 1996. The Company supports restructuring and unbundling
the transmission, gathering, storage, customer service and gas supply
functions. Unbundling should enhance customer choices, service and value and
potentially should decrease unit costs, increase throughput, allow broader use
of the Company's assets, and strengthen economic development.

The Company plans to launch two new ventures to enhance its marketing group.
ONEOK Producer Services will bring gas marketing and other services to the
small gas producer to fill a niche market. In addition, the Company has filed
an application with FERC to market electricity.

This graph illustrates consolidated earnings per share of $1.93 in 1996, $1.58
in 1995, and $1.34 in 1994.

   
RESULTS OF OPERATIONS - The continued strong performance of the Company's 
regulated business, the rapid growth of the gas marketing segment and
organizational changes implemented to maximize the value of its nonregulated
businesses contributed to an increase in consolidated net income of $10 million
or 23.4% over the prior year. Earnings attributable to the regulated business 
increased by $4 million in 1996 over the prior year as a result of reduced costs
and increased margins. The $6 million increase in net income for the
nonregulated business in 1996 over the prior year is primarily attributable to
the growth of the gas marketing operations as a result of weather related 
demand and effectively combining gas supply and 
    




                                      17

<PAGE>   18
   
commodity derivative knowledge in order to match buyers and sellers. Use of
derivative instruments, such as futures contracts and swaps, allows ONEOK Gas
Marketing to accept physical supply and sale contracts which use different
price indices and hedge the price risk to the Company.

Net income rose 6.6 million in 1995 over the prior year as a result of increases
in regulated and nonregulated earnings of $1 million and $5.6 million,
respectively. The increased earnings of the nonregulated businesses is
primarily attributable to an increase in natural gas liquids production related
to the acquisition of oil and gas reserves in Louisiana and lower fuel and
shrink prices.

RISK MANAGEMENT - To minimize the risk from market fluctuations in the price of
natural gas and oil, the company's nonregulated operations use commodity
derivative instruments such as future contracts, swaps and options
(collectively, derivatives) to hedge existing physical gas inventory, and
purchase or sale commitments. None of these derivatives are held for speculative
purposes and, in general, the Company's risk management policy requires that
positions taken with derivatives be offset by positions in physical
transactions or other derivatives. For each of the years in the three year
period ended August 31, 1996, derivatives were primarily used by ONEOK Gas
Marketing as a method of eliminating unacceptable risks with respect to changes
in the price of gas or the cost of the intervening transportation associated
with certain contracts.

During 1996, the Company's Production segment increased its utilization of
derivatives in order to hedge anticipated sales of oil and natural gas
production. These anticipated transactions have been hedged with commodity
swaps agreements whereby the Company is able to set the price to be received
for the future production and thus eliminate the risk of declining market prices
between the origination date of the swap and the month of production. The
Company's strategy is hedging anticipated transactions is to eliminate the
variability in earnings of its Production segment as a result of market
fluctuations. To the extent that management does not terminate a hedge or enter
into an opposing derivative, the current strategy will limit the potential
gains which could result from increases in market prices above the level set by
the hedge.

The Company adheres to policies and procedures which limit its exposure to
market risk from open positions and monitors daily its exposure to market risk.
The results of the Company's derivative trading activities continue to meet its
stated objectives. For further discussion, see OTHER, Price Risk Management at
page 25 and note (h) to the consolidated financial statements.

ACCOUNTING POLICIES - The regulated operations of the Company are primarily
subject to accounting requirements of the Oklahoma Corporation Commission (OCC)
and the provisions of Statement of Financial Accounting No. 71 "Accounting for
the Effects of Certain Types of Regulation". Accordingly, the allocation of
costs and revenues to accounting periods for ratemaking and regulatory purposes
may differ from bases generally applied by nonregulated companies. Such
allocations to meet regulatory accounting requirements are considered to be
generally accepted accounting principles for regulated utilities provided that
there is a demonstrable ability to recover any deferred cost in future rates.
    

The Company views its segments as operating within either a rate regulated
environment (Regulated Operations) or a nonregulated (Nonregulated Operations).
The nonregulated environment is further viewed as having three primary,
vertically integrated segments: marketing, processing and production. In order
to align this view with its financial reporting, the Company, beginning this
year, is presenting the combined results of each operating environment.
Nonregulated segment data is reported by process rather than entity.

REGULATED OPERATIONS

Oklahoma Natural Gas is a fully integrated intrastate natural gas distribution
and transmission business, which purchases, stores, transports, and distributes
natural gas for sale to wholesale and retail customers primarily in the State
of Oklahoma, and leases pipeline capacity to customers for their use in
transporting natural gas to their facilities. ONG Transmission Company
transports gas for others under Section 311(a) of the Natural Gas Policy Act of
1978 (NGPA). Oklahoma Natural Gas Company, ONG Transmission Company, ONGSayre
Storage Company, and ONG Gas Gathering Company are consolidated for ratemaking
purposes by the Oklahoma Corporation Commission.

OPERATIONAL HIGHLIGHTS - In the last two rate cases, sweeping changes were
proposed to the way business had previously been conducted in order to be more
competitive and to stabilize and improve earnings capacity. The rate structure
that was approved shifted a significant amount of margin to core residential
and commercial customers, and offset that shift by gas cost reductions.

The Company dominates the core energy service markets with over a 90 percent
market share for water heating, cooking and home heating. Annual cost
comparisons with electricity for these same services indicate that gas costs
were at least 50 percent less, the largest difference being in home heating at





                                      18

70 percent less. On a gas to gas comparison, Oklahoma Natural Gas Company rates
were lower than the regional and national averages for residential, firm
industrial and interruptible industrial services.

In 1996, significant changes occurred in the way the Company conducts its
business. Highlights of those changes are:

o    Implemented a performance-based compensation system for all employees.

o    Shifted the source of the net revenues from the industrial customer to the
     core residential and commercial customers. In 1996, 80 percent of net
     revenues was derived from gas sales and PCL revenues from the core
     customers, as compared to 63 percent in 1995 and 1994. Despite this shift
     in net revenues, the core customers experienced a net decrease in their
     cost of gas due to changes in gas purchasing and pricing practices.

o    Strengthened cost controls throughout the organization. Total employees
     dropped by approximately six percent while increasing the number of
     customers by approximately two percent. This was accomplished through
     attrition and without compromising customer safety.

REGULATORY INITIATIVES - The OCC's NOI on restructuring Oklahoma's gas utility
industry has set into motion the process of unbundling products and services.
The Company believes and has stated in its response to the NOI that it
envisions a restructured rate environment in which competition replaces the
traditional regulated, full merchant utility function. The Company supports the
unbundling of at least the transmission, gathering, storage, customer service
and gas supply functions; however, because of the inefficient and costly
duplication of certain functions, such as local distribution service,
regulation will continue to be necessary in certain areas. Unbundling of the
appropriate services could be accomplished within three to five years after
final OCC approval.

Customer choice is the driving force behind the restructuring efforts and will
ultimately provide a wide array of services from which to choose. The Company
has already unbundled the gas supply function for many industrial and large
commercial customers through the PCL program and envisions the separation of
the gas supply function, referred to in the industry as "open access", as the
first step in unbundling for small commercial and residential customers. The
Company intends to file for OCC permission for a pilot open access project
during the coming year and anticipates that open access can be accomplished
within two years after the OCC adopts the final rules.

RATE CASE ACTIVITIES - November 1994 Rate Order - Ratified a $23.7 million rate
increase of which $18.2 million had been approved on an interim basis in
February of 1992. The rate order also established a monthly connection fee that
will reduce the impact of seasonality of weather on earnings.

June 1995 Rate Order - Reduced the cost of service to the large industrial
customers and shifted the reduction to the core customers through a tariff
rider. Changes to gas purchasing and pricing practices offset the impact of the
tariff rider and provide a net savings to the customer. A temperature
normalization clause was adopted to further reduce the impact of seasonality on
earnings. As part of the settlement, the Company agreed not to file for a
general rate increase for two years.

CAPITAL EXPENDITURES - The Company's capital expenditure program includes
expenditures for extending service to new areas, increasing system capabilities
and general replacements and betterments. The 1996 capital expenditure program
included $10 million for new business development and $2 million to improve
peak storage deliverability. It is the Company's practice to maintain and
periodically upgrade facilities to assure safe, reliable and efficient
operations.

OPERATING RESULTS - Higher gross margins on gas sales result primarily from
rate increases granted under the two rate cases completed in fiscal 1995 and
higher usage billed during the winter heating season which lasts from November
through April. Actual degree days in the 1996 heating season approximated
normal (3,632 degree days) and accordingly the Temperature Adjustment Clause
(TAC)




                                      19

<PAGE>   20
had little impact on gas margins. Fluctuations in gas margins in 1995 and 1994
(prior to the implementation of the TAC) are directly attributable to weather
as evidenced by total degree days of 3,358 and 3,874 during the respective
winter heating seasons. Degree days is an industry measure of temperature
variations from an established normal temperature of 65 degrees; a higher
number of degree days reflects colder weather on the average. Despite an
increase in the spot market price of gas during 1996 from 1995, the Company
achieved a reduction in the cost of gas through changes in its gas purchasing
and pricing practices approved in the June 1995 rate case. Fluctuation in the
costs of gas from 1995 to 1994 reflects volume and spot market fluctuations.
The significant decrease in PCL margins reflects the rate restructuring
completed in 1995 which lowered rates to our large industrial customers in
order to compete more effectively.

Operating expenses remained relatively unchanged in 1996 as compared to 1995
despite an $8.7 million increase in post-retirement benefit expense. Prior to
the June 1995 rate case, such cost was deferred pending regulatory approval.
Offsetting this increase in expense were reductions in labor costs, property
damage claims and other operations and maintenance expenses. The increase in
operating expenses in 1995 as compared to 1994 reflects increases in
compensation relating to lump-sum incentive costs resulting from the attainment
of corporate performance objectives and the recognition of net periodic pension
costs previously deferred pending regulatory approval in the November 1994 rate
case.

NONREGULATED OPERATIONS

The Company's nonregulated operations are involved in the production,
processing and marketing of natural gas, oil and natural gas liquids. As a
result of acquisitions and dispositions during the third quarter of 1996, the
Company's producing properties are concentrated principally in Oklahoma where
it also owns nonoperated interests in 15 gas liquids extraction plants. The gas
marketing subsidiary directs its activities to end users in the mid-continent
region of the United States. The Company also operates its headquarters office
building and a parking garage.

MARKETING

OPERATIONAL HIGHLIGHTS - The Company's marketing operation purchases and
markets natural gas, primarily in the mid-continent area of the United States.
Several operational changes instituted throughout the current year included
increased use of gas storage facilities, hedging and transportation
arbitraging. This allows the Company to capitalize on day-to-day pricing
volatility by managing positions and moving large volumes of gas in short
periods of time.





                                      20

<PAGE>   21
Beginning in 1997, the Company expects to introduce ONEOK Producer Services, an
entity which will specialize in servicing small producers. Services will
include well connection identification and facilitation, production balancing
to nominated volumes and handling certain administrative accounting functions.

The Company has filed an application with FERC to market electricity.
Management anticipates that permits will be granted during the first quarter of
1997. It is not anticipated that such activities will be a major contributor to
earnings in 1997.

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


PRICE RISK MANAGEMENT - In order to mitigate the financial risks arising from
fluctuations in both the market price and transportation costs of natural gas,
the Company routinely enters into natural gas futures contracts, swaps and
options as a method of protecting its margins on the underlying physical
transactions. However, net open positions in terms of price, volume and
specified delivery point do occur. For further discussion, see OTHER, Price
Risk Management at page 25.

OPERATING RESULTS - The increase in profitability of the marketing business
reflects the impact of the additional volume and price volatility resulting
from weather related demand. As important, the Company focuses on serving a
niche market of daily production trading. Such demand is precipitated by
customers who have volatile consumption throughout a month or acquire a portion
of their operating needs on the spot market as a method of hedging price
changes. This sector of the market is potentially more profitable due to spot
market volatility. In any one month, approximately 80 to 90 percent of the
Company's volume results from such trading. In January 1995, the Company
acquired the remaining 50 percent interest in a gas marketing entity. The
results of operations attributable to this investment are included in operating
costs prior to that date.

PROCESSING

OPERATIONAL HIGHLIGHTS - The Company's processing operation has nonoperating
interests in 15 gas processing plants whose operations include the extraction
and separation of natural gas liquids (NGLs) into distinct products (e.g.,
ethane, butane, propane and isobutane). Under certain market conditions it may
become unprofitable to separate and sell certain products, a process referred
to as rejection. Other factors contributing to the volatility in earnings are
fluctuations in the price of natural gas which is consumed as "fuel and
shrinkage" in the extraction process, fluctuation in the discreet market prices
of NGLs, competition or processing plant capacity utilization.

Processing plant enhancement completed during 1996 included an expansion of the
gathering systems behind certain plants, development of producer alliances and
bringing most gas processing plants to capacity. The Company's joint interest
partner completed construction of a gathering system servicing




                                      21

<PAGE>   22
three processing plants. Management is pursuing producer alliances which will
provide economical supplies and the dedication of additional production to the
plants. Currently, 12 of the Company's processing plants are on-line and
running at or near capacity.

CAPITAL EXPENDITURES - The Company's portion of the gathering field addition
was approximately $3.2 million. The remaining $2 million in capital
expenditures during 1996 related to capital required to sustain operations.
Prior years' expenditures generally related to capital required to sustain
operations.

OPERATING RESULTS - Gas processing revenue rose, reflecting improving market
conditions for NGLs. NGL sales volumes were lower, due to rejection.

PRODUCTION

OPERATIONAL HIGHLIGHTS - The Company's strategy is to concentrate ownership of
hydrocarbon reserves in Oklahoma in order to add value not only to its existing
production operations but also to the related processing, marketing,
transmission, and storage businesses. Accordingly, the Company intends to focus
on exploitation activities rather than exploratory drilling.

The volatility of energy prices has a significant impact on the profitability
of this segment. In an effort to manage price risk as much as possible, the
production segment expanded its hedging program in late 1996. As of August 31,
1996, approximately 76 percent of anticipated gas production in 1997 has been
hedged primarily with swap agreements.

CAPITAL EXPENDITURES - During 1996, the Company purchased substantially all of
the Oklahoma oil and natural gas properties of SCANA Petroleum Resources, Inc.
The $43.1 million purchase included over 500 producing properties of which 90
percent are natural gas. Also in 1996, the Company sold all of its oil and gas
properties in Alabama and Mississippi for approximately $18.9 million. The
Company acquired working interests in oil and gas reserves located in Louisiana
for approximately $18.3 million in 1995.

Capital expenditures related to a limited drilling program were approximately
$3.4 million, $5.9 million and $8.3 million in 1996, 1995 and 1994,
respectively.

OPERATING RESULTS - Net production revenues rose reflecting increased
production capabilities over the last two years and an increase in natural gas
prices during 1996 to 1994 levels. Other production revenue includes the gain
on sale of the Alabama and Mississippi properties in the third quarter of 1996.
Effective March 1, 1996, the Company adopted 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, which requires impairment losses
to be recognized for long-lived assets when indicators of impairment are
present and the undiscounted cash flows are not sufficient to recover the
assets carrying amount. The impairment loss is measured by comparing the fair
value of the asset to its carrying amount. Fair values are based on discounted
future cash flows or information provided by sales and purchases of similar
assets. Under SFAS No. 121, the Company now evaluates impairment of production
assets on a field by field basis rather than using a total company basis for
its proved properties. As a result, the Company recognized a pre-tax impairment
loss of $8.6 million in 1996.

LIQUIDITY AND CAPITAL RESOURCES

CASH FLOW ANALYSIS

Cash provided by operating activities remains strong and continues as the
primary source for meeting cash requirements. However, due to seasonal
fluctuations and additional capital requirements, the Company accesses funds
through a short-term credit agreement and, if necessary, through long-term
borrowings. The Company believes that internally generated funds and existing
credit agreements will be sufficient to meet its debt service, dividend payment
and capital expenditure requirements. However, certain events, such as
significant acquisitions, may require additional long-term debt or equity
financing. The following discussion of cash flows should be read in conjunction
with the Company's Consolidated Statement of Cash Flows and the supplemental
cash flow information included in note O of Notes to Consolidated Financial
Statements.

OPERATING CASH FLOW

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

 Cash provided by operating activites      $105,050      $109,559      $80,274
- --------------------------------------------------------------------------------


Income before deferred taxes and depreciation, depletion and amortization
increased by approximately $43 million in 1996 reflecting the overall increase
in net income, changes in the components of current and deferred taxes and the
recovery through rates of deferred costs settled in the 1995 rate proceedings.
This increase from earnings was partially offset by fluctuations in the level
of gas in storage and the timing of the recovery of gas costs. In late 1996,
the Company received permission from the OCC to change its method of recovering
purchased gas costs which had accumulated during the winter heating season
resulting from the base cost of gas set during the June 1995 rate proceeding.
In addition, the OCC will allow periodic changes in the base gas cost in order
to reduce the impact on cash flow of future fluctuations in the weighted
average cost of gas.

Income before deferred taxes and depreciation, depletion and amortization was
$21 million lower in 1995 as compared to 1994 despite higher earnings in 1995,
reflecting changes in the components of current and deferred taxes. This was
offset by significant reductions in both gas in storage and the level of
recovery of purchased gas costs.

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


CAPITAL EXPENDITURES - Total capital expenditures increased in both 1996 and
1995; however, as discussed in the "Results from Operations," this is
attributable to the acquisition of production assets for approximately $43
million and $18 million in each of those years respectively. Capital
expenditures for 1997, excluding potential acquisitions, are estimated to be
$63 million.

                     CAPITAL EXPENDITURES AND ACQUISITIONS
          ---------------------------------------------------
                                       1996     1995   1994

This graph illustrates capital expenditures and acquisitions of $52,291,000
expenditures and $43,064,000 acquisitions in 1996, $64,157,000 expenditures and
$18,000,000 acquisitions in 1995 and $62,000,000 expenditures and $0.00
acqusitions in 1994.

ASSET SALES - Approximately $18 million and $8 million of proceeds were
received in 1996 and 1994, resulting from the sale of production and drilling
assets in 1996 and 1994, respectively. The sale of a pipeline investment for
its approximate book value generated approximately $10.2 million in proceeds in
1995.

FINANCING CASH FLOW

- -------------------------------------------------------------------------------
 Cash used in financing activities     $44,966        $38,306        $17,039
- -------------------------------------------------------------------------------


SHORT-TERM DEBT - The Company uses short-term debt to help meet its need for
operating funds, which fluctuates with seasonal demands for gas purchases, the
levels of gas in storage and the Unrecovered Purchased Gas Cost (UPGC). A
short-term unsecured credit agreement with several banks provides aggregate
borrowings of up to $125 million for general corporate purposes. A master note
with Bank of America provides an additional $30 million of borrowing capability.
The maximum amount of short-term debt authorized by the Board of Directors is
$150 million. Fluctuation in the amount of cash used in financing activities in
each of the years presented is primarily a factor of short-term borrowings.

LONG-TERM DEBT - As of August 31, 1996, the Company could have issued
approximately $292.5 million of additional long-term debt under the most
restrictive provisions contained in its various borrowing agreements. With the
current mix and relative sizes of the Company's businesses, Company goals are
to achieve an equity to capital ratio of approximately 50 percent and to
preserve or improve its current debt ratings. At August 31,1996, the equity
component was 51 percent as compared to 49 percent a year ago. Debt ratings are
A3 by Moody's Investor Service and A- by Standard and Poor's Corporation. No
long-term debt is currently callable, and only the 8.7 percent, 9.7 percent and
9.75 percent series have call options commencing in October 1996, and December
1999 and 2000, respectively. No long-term debt was issued in the last three
years.

STOCK AND DIVIDENDS - The Company had approximately 28 million shares of common
stock, 160,000 shares of preferred stock and 3 million shares of preference
stock available for issue at August 31, 1996, 1995 and 1994. Common stock
dividends were $1.18, $1.12 and $1.11 per share in 1996, 1995 and 1994,
respectively. Preferred stock dividends were $2.375 in each of the three years.

Company's Stock Purchase and Dividend Reinvestment Program $2.04 million of
dividends were reinvested into common stock during 1996.

LIQUIDITY - The regulated businesses continue to face competitive pressure to
serve the substantial market represented by its large industrial customers. The
loss of a substantial portion of its industrial load, without recoupment of the
revenues from that loss, would have a materially adverse effect on the
Company's financial condition. The Company has successfully competed for such
load in large part with such innovative methods as its PCL and SISP programs.
These programs were all designed to provide competitive alternatives for
Oklahoma industry. Rate restructuring achieved in the June 1995 rate order
further reduces the Company's risk in serving its large industrial customers.

OTHER

PRICE RISK MANAGEMENT - Commodity futures contract options and swaps are
periodically used in the production, gas processing, and marketing operations
to hedge the impact of natural gas price fluctuations. Natural gas futures
require the Company to buy or sell natural gas at a fixed price. Under swap
agreements, the Company receives or makes payments based on the differential
between a specified price and the actual price of natural gas. Swaps and
options allow the Company to commit to purchase gas at one location and sell it
at another location without assuming unacceptable risk with respect to changes
in price or the cost of the intervening transportation. Natural gas options
held to hedge price risk provide the right, but not the requirement, to buy or
sell natural gas at a fixed price. The Company utilizes options to manage
margins and to limit overall price risk exposure. The Company's production
operation periodically uses commodity futures contracts and swaps to hedge the
impact of oil and natural gas price fluctuations. The Company's gas processing
operation uses futures to hedge the price of gas used in the natural gas liquid
extraction process. The gas marketing operation uses futures, options and swaps
to lock in margins on preexisting purchase or sale commitments for physical
quantities of natural gas. The Company adheres to policies and procedures which
limit its exposure to market risk from open positions and monitors daily its
exposure to market risk. Gains and losses on commodity futures contracts and
swaps are recognized in income when the underlying physical transactions are
closed. At August 31, 1996, the net deferred gain on these contracts was
approximately $4.9 million.

NEW ACCOUNTING PRONOUNCEMENTS - In October 1995, the Financial Accounting
Standards Board issued SFAS No. 123, Accounting for Stock-Based Compensation,
which will become effective for years beginning after December 15, 1995. This
Statement will require that financial statements include certain disclosures
about stock-based employee compensation and allows, but does not require, a
fair value-based method of accounting for such compensation. The Company will
not adopt the fair value-based method of accounting, however, it will make the
required disclosures in future stockholder reports.

standards. 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 consolidated financial statements referred to above present
fairly, in all material respects, the financial position of ONEOK Inc. and

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(A)  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

NATURE OF OPERATIONS - ONEOK Inc. and subsidiaries (collectively, the Company)
is a diversified energy company engaged in the production, processing, storage,
transportation, distribution and marketing of environmentally clean fuels and
products. The Company's business units are characterized as operating within
either a rate regulated environment (Regulated Operations) or a nonregulated
environment (Nonregulated Operations). The regulated business units provide
natural gas distribution and transmission for about 75 percent of Oklahoma and
during 1996 generated approximately 80 percent of operating income before
income taxes. The nonregulated business has segments involved in various
aspects of natural gas marketing, processing and production. The Company's
other segment, whose results of operations are not material, operate and lease
the Company's headquarters building and parking facility.

CONSOLIDATION - The consolidated financial statements include the accounts of
ONEOK Inc. and its wholly owned subsidiaries. All significant intercompany
accounts and transactions have been eliminated in consolidation.

   
REGULATION - The regulated operations of the Company are primarily subject to
the rate regulation and accounting requirements of the Oklahoma Corporation
Commission (OCC). Certain other regulated activities of the Company are subject
to regulation by the Federal Energy Regulatory Commission (FERC) and the
Railroad Commission of Texas. Accordingly, the regulated operations follow the
accounting and reporting guidance contained in Statement of Financial
Accounting Standards No. 71, "Accounting for the Effects of Certain Types of
Reulations".  Allocation of costs and revenues to accounting periods for 
ratemaking and regulatory purposes may differ from bases generally applied by 
nonregulated companies. Such allocations to meet regulatory accounting 
requirements are considered to be generally accepted accounting principles 
for regulated utilities provided that there is a demonstrable ability to 
recover any deferred costs in future rates.

During the rate-making process, regulatory commission's may require a utility
to defer recognition of certain costs to be recovered through rates over time
as opposed to expensing such costs as incurred.  This allows the utility to
stabilize rates over time rather than passing such costs on to the customer for
immediate recovery.  This causes certain expenses to be deferred as a reulatory
asset and amortized to expense as it is recovered through rates.  Total
regulatory assets resulting from this deferal process are approximately $155
million and $167 million at August 31, 1996 and 1995 respectively.  See
footnote B.
    

REVENUE RECOGNITION - The Company recognizes revenue when services are rendered
or product is delivered. Major industrial and commercial gas distribution
customers are invoiced as of the end of each month. Certain gas distribution
customers, primarily residential and some commercial, are invoiced on a cycle
basis throughout each month, and the Company accrues unbilled revenues at the
end of each month. Beginning in 1996, the Company's rate tariff for residential
and commercial customers contains a temperature normalization clause that
provides for billing adjustments from acutal volumes to normalized volumes
during the winter heating season. Revenues from marketing, processing and
production are recognized on the sales method. Credit is granted to these
customers under customary terms.

REGULATED PROPERTY - Regulated distribution, transmission, and storage property
is stated at cost. Such cost includes personnel costs, general and
administrative costs, and an allowance for funds used during construction. The
allowance for funds used during construction represents the capitalization of
estimated average cost of borrowed funds (8.50 percent, 8.24 percent, and 8.21
percent, in 1996, 1995, and 1994, respectively) used during the construction of
major projects and is recorded as a credit to earnings.

Depreciation is calculated using the straight-line method based upon rates
prescribed for ratemaking purposes. The average depreciation rate approximated
3.6 percent in 1996, 3.7 percent in 1995, and 3.8 percent in 1994.

Maintenance and repairs are charged directly to expense. Generally, the cost of
property retired or sold, plus removal costs, less salvage, is charged to
accumulated depreciation. Gains and losses from sales or transfers of operating
units or systems are recognized in income.

PRODUCTION PROPERTY - The Company uses the successful-efforts method to account
for costs incurred in the acquisition and exploration of oil and natural gas
reserves.  Costs to acquire mineral interests in proved reserves, and to drill
and equip development wells are capitalized.  Geological and geophysical costs
and costs to drill exploratory wells which do not find proved reserves are
expensed.  Unproved

oil and gas properties which are individually significant are periodically
assessed for impairment of value, and a loss is recognized at the time of
impairment by providing an impairment allowance. The remaining unproved oil and
gas properties are aggregated, and an overall impairment allowance is provided
based on the Company's experience.

   
Depreciation and depletion are calculated using the unit-of-production method
based upon periodic estimates of proven oil and gas reserves. Undeveloped
properties are amortized based upon remaining lease terms and exploratory and
developmental drilling experience.
    

OTHER PROPERTY - Gas processing plants and all other properties are stated at
cost. Gas processing plants are depreciated using various rates based on
estimated lives of available gas reserves. All other property and equipment is
depreciated using the straight-line method over its estimated useful life.

INVENTORIES - Materials and supplies are priced at average cost. 
Noncurrent gas in storage is classified as property and is priced at cost.
Current gas in storage is valued using the last-in, first-out method. The
estimated replacement cost of current gas in storage was $81.5 million at
August 31, 1996, and $72.4 million at August 31, 1995.

INCOME TAXES - Deferred income taxes are recognized for the tax consequences of
"temporary differences" by applying enacted statutory tax rates applicable to
future years to differences between the financial statement carrying amounts
and the tax bases of existing assets and liabilities. The effect on deferred
taxes of a change in tax rates is deferred and amortized for the OCC regulated
operations and, for nonregulated operations, is recognized in income in the
period that includes the enactment date. The Company continues to amortize
previously deferred investment tax credits on gas distribution and transmission
properties over the period prescribed by the OCC for ratemaking purposes.

COMMODITY PRICE RISK MANAGEMENT - To minimize the risk from market fluctuations
in the price of natural gas and oil, the Company enters into futures
transactions, swaps and options in order to hedge existing physical gas
purchase or sale commitments. Gains and losses resulting from changes in market
value of the various derivative instruments utilized as hedges are recognized
in income when the underlying physical transaction is closed.

   
IMPAIRMENTS - Effective March 1, 1996, the Company adopted 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, which requires
impairment losses to be recognized for long-lived assets when indicators of
impairment are present and the undiscounted cash flows are not sufficient to
recover the assets carrying amount. The impairment loss is measured by
comparing the fair value of the asset to its carrying amount. Fair values are
based on discounted future cash flows or information provided by sales and
purchases of similar assets. Under SFAS No. 121, the Company now evaluates
impairment of production assets on the lowest possible level, (a field by 
field basis) rather than using a total company basis for its proved 
properties. Primarily due to downward reserve revisions for certain proven
properties in its year-end reserve study, the Company in accordance with SFAS
No. 121 recognized a pre-tax impairment loss of $8.6 million in 1996, such 
loss is included in depreciation, depletion and amortization expense. Prior to
the adoption of SFAS No. 121, the Company evaluated impairment of its proven
reserves using a discounted cash flow approach on a total company basis which 
aggregates all properties for purposes of determining impairment.
    

USE OF ESTIMATES - Management has made a number of estimates and assumptions
relating to the reporting of assets and liabilities and the disclosure of
contingent assets and liabilities to prepare these financial statements in
conformity with generally accepted accounting principles. Actual results could
differ from these estimates.

EARNINGS PER COMMON SHARE - The computation of earnings per common share is
based on the weighted average number of shares of common stock outstanding.
Unexercised stock options do not have a material dilutive effect on the
reported amount of earnings per common share.

COMMON STOCK OPTIONS AND AWARDS - The Company follows the intrinsic value
method of accounting for common stock options and awards issued to employees.

<PAGE>   35
CASH AND CASH EQUIVALENTS - Items classified as cash equivalents for the
purpose of the Consolidated Statements of Cash Flows include highly liquid
temporary investments, with original maturities of three months or less, in
"money market" or "pooled" investment accounts backed by government securities,
bank certificates of deposit, or bank lines of credit.

RECLASSIFICATION - Certain amounts in the 1995 and 1994 consolidated financial
statements have been reclassified to conform with the 1996 presentation.

(B)  REGULATORY ASSETS

The following table is a summary of regulatory assets, net of amortization:

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

   
Certain of the regulatory assets listed above are being recovered through
rates, but the Company is not being allowed to earn a rate of return on the
unrecovered balance. The remaining recovery period is set forth in the table
below.

- ----------------------------------------------------------
</TABLE>

Postemployment benefit costs are currently being deferred as a regulatory
asset because the methodology of their recovery has not yet been determined in
rate proceedings.
    

The Company incurred approximately $3.1 million of recoupable costs 
attributable to resolutions of take-or-pay and pricing issues during 1995. No 
additional costs were incurred in 1996. The OCC has authorized recovery of the 
take-or-pay settlement costs through a combination of a surcharge to customers 
and revenues derived from certain transportation customers.

The pension and postretirement benefit costs previously deferred are currently
being recovered through revenue and are being amortized to expense over a 10 to
18 year period. As discussed in note G, the OCC also approved recovery of 
pension and postretirement benefit costs through rates. The Company
anticipates that postemployment benefit costs will be recovered in future rate
filings. Amortization expense related to regulatory assets was approximately
$11.7 million, $8.2 million, and $3.1 million in 1996, 1995, and 1994,
respectively. An additional $2.1 million was recovered through gas purchase
expense during 1995.

(C) LINES OF CREDIT AND SHORT-TERM NOTES PAYABLE

At August 31, 1996, the Company had a short-term unsecured credit agreement
with several banks pursuant to which the banks have agreed to make loans to the
Company from time to time in an aggregate amount not to exceed $125 million at
any one time for general corporate purposes. The short-term credit agreement
provides a back-up line of credit for short-term debt from other sources in
addition to providing short-term funds. The facility fee requirement for this
line of credit is .075 percent applied annually to the total line of credit.
Borrowings under the agreement bear interest at offshore IBOR rates plus .200
percent per annum. No compensating balance requirements existed at August 31,
1996. A master note with Bank of America provides an additional $30 million of
borrowing capability.

Short-term notes payable totaling $50.2 million at August 31, 1996, and $55.3
million at August 31, 1995, were outstanding. The notes carried average
interest rates of 5.61 percent and 6.16 percent, respectively.

(D) LONG-TERM DEBT

All long-term notes payable at August 31, 1996, are unsecured. The aggregate
current maturities of long-term debt for each of the five years ending August
31, 2001, are $15.1 million; $15.1 million; $13.1 million; $16.1 million; and
$14.7 million, respectively, including $1.1 million each year callable at the
option of the holder.

(E) CAPITAL STOCK

The holders of Series A preferred stock have full voting rights (two votes per
share) and may redeem those shares in whole or in part at any time at the
option of the Company. Holders are entitled to $53 per share, plus all
dividends accrued or in arrears thereon, upon voluntary redemption or
liquidation and $50 per share upon involuntary liquidation. No dividends were
in arrears at August 31, 1996.

The Company has authorized three million shares of preference stock, none of
which was outstanding at August 31, 1996, and approximately 28 million shares
of unrestricted common stock available for issue. The Board has reserved two
million shares of the Company's common stock for the Direct Stock Purchase and
Dividend Reinvestment Plan of which 192,228 shares were issued in 1996; and has
reserved approximately three million shares for the Thrift Plan for Employees
of ONEOK Inc. and Subsidiaries.

In 1996, the Company approved the Key Employee Stock Plan which provides for
compensation of certain officers and key employees with common stock or cash
through various types of awards, including stock options, stock bonus,
performance units and restricted stock. To date, 100,000 fixed options have
been granted at an exercise price of $23.69; no options are exercisable by the
employee until November 1996. No other awards have been granted. The Stock
Performance Plan expired in 1996. During 1995, $1.9 million was expensed and
48,414 shares of common stock were issued in conjunction with this predecessor
plan. No amounts were expensed in 1994. The Board has reserved 1,000,000 shares
of common stock for this plan.

Also in 1996, the Company approved the Employee Stock PurchasePlan which is a
non-compensatory plan that allows substantially all employees to purchase
common stock at a 15 percent discount. The Board has reserved 350,000 shares of
common stock for this plan.

Under the most restrictive covenants of the Company's loan agreements, $192.4
million (87.5 percent) of retained earnings at August 31, 1996, was available
to pay dividends.

The projected benefit obligation was determined using an annual discount rate
of 7.75 percent for 1996 and 1995; a long-term rate of return on plan assets of
8 percent and 9 percent for 1996 and 1995, respectively; and an average assumed
long-term annual rate of salary increases of 4 percent and 5 percent for 1996
and 1995, respectively.

OTHER POSTRETIREMENT BENEFIT PLANS - The Company sponsors a defined benefit
health care plan that provides postretirement medical benefits and life and
accidental death and dismemberment benefits to substantially all employees who
reach normal retirement age while working for the Company. The plan is
contributory, with retiree contributions adjusted periodically, and contains
other cost-sharing features such as deductibles and coinsurance. The Company
began funding the plan in September 1996.

The Company elected to delay recognition of the accumulated postretirement
benefit obligation (APBO) of approximately $72.2 million and amortize it over
20 years as a component of net periodic postretirement benefit cost.




                                      38

Net periodic postretirement benefit cost includes the following components:

  Net periodic postretirement benefit cost               $   10,980   $   10,710
================================================================================


For measurement purposes, an 8.85 percent annual rate of increase in the per
capita cost of covered medical benefits (i.e., medical cost trend rate) was
assumed for 1996, the rate was assumed to decrease gradually to 5.0 percent by
the year 2003 and remain at that level thereafter. The medical cost trend rate
assumption has a significant effect on the amounts reported. For example,
increasing the assumed medical cost trend rate by one percentage point in each
year would increase the accumulated postretirement benefit obligation as of
August 31, 1996, by $10.9 million and the aggregate of the service and interest
cost components of net periodic postretirement benefit cost for the year ended
August 31, 1996, by $1.4 million.

The weighted average discount rate used in determining the accumulated
postretirement benefit obligation was 7.75 percent at August 31, 1996.

The following table presents the plan's funded status reconciled with amounts
recognized in the Company's consolidated balance sheet.

EMPLOYEE THRIFT PLAN - The Company has a Thrift Plan covering all employees.
Employee contributions are discretionary. Subject to certain limits, employee
contributions are matched by the Company. The annual cost of the plan was $3.7
million in 1996; $3.4 million in 1995; and $3.7 million in 1994 .


POSTEMPLOYMENT BENEFITS - The Company pays postemployment benefits to former or
inactive employees after employment but before normal retirement.


REGULATORY TREATMENT - The OCC has approved the recovery of pension costs and
other postretirement benefit costs through rates. The costs recovered through
rates are based on current funding requirements and the net periodic
postretirement benefit cost for pension and postretirement costs, respectively. 
Differences, if any, between the expense and the amount ordered through rates
are charged to earnings.

(H)  FINANCIAL INSTRUMENTS AND RISK MANAGEMENT

FINANCIAL INSTRUMENTS - The following table presents the carrying amounts and
fair values of certain of the Company's financial instruments. Fair value is
defined as the amount at which the instrument could be exchanged in a current
transaction between willing parties. The estimated fair value of long term debt
and notes payable have been determined using quoted market prices of same or
similar issues, discounted cash flows and/or rates currently available to the
Company for debt with similar terms and remaining maturities. The fair value of
natural gas and oil swaps, options and futures contracts generally reflect the
estimated amounts that the Company would pay or receive to terminate the
contracts at the reporting date, thereby taking into account the unrealized
gains and losses on open contracts. There is no readily available market for
natural gas swaps. The items presented without a carrying value are off-balance
sheet financial instruments. All of the Company's financial instruments are
held for purposes other than trading.

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


RISK MANAGEMENT - The Company's gas marketing, processing and production
operations subject the Company's earnings to variability based on fluctuations
in both the market price and transportation costs of natural gas and oil. The
Company's exposure arises from fixed price purchase or sale agreements which
extend for periods of up to 48 months. In order to mitigate the financial risks
associated with such activities the Company routinely enters into natural gas
and oil futures contracts, swaps and options, collectively referred to herein
as derivatives. Net open positions in terms of price, volume and specified
delivery point do occur.

The futures contracts are purchased and sold on the New York Mercantile
Exchange (NYMEX ) and require the Company to buy or sell natural gas at a fixed
price. Swap agreements generally require one party to make payments based on
the difference between a fixed price or fixed differential from the NYMEX price
while the other party pays a price based on a published index. Swaps and
options allow the Company to commit to purchase gas at one location and sell it
at another location without assuming unacceptable risk with respect to changes
in the price of the gas or the cost of the intervening transportation. Natural
gas options held to hedge price risk provide the right, but not the
requirement, to buy or sell natural gas at a fixed price. The Company utilizes
options to manage margins and to limit overall price risk exposure. None of
these derivatives are held for speculative purposes and, in general, the
Company's risk managment policy requires that positions taken with derivatives
be offset by positions in physical transactions or other derivatives.

The total notional value of futures purchased and sold is $99.6 million and
$101 million, respectively, at August 31, 1996. The term "notional amount"
refers to the current contract unit price times the contract volume for the
relevant derivative. In general, such amounts are not indicative of the cash
requirements associated with these derivatives. The notional amount is intended
to be indicative of the Company's level of activity in such derivatives,
although the amounts at risk are significantly




                                      40

smaller because, in general, changes in market value of these derivatives are
offset by changes in the value associated with the underlying physical
transaction or other derivatives.

(A) Represents the estimated amount which would have been recognized upon
termination of the relevant derivatives as of the date indicated. The amount
which is ultimately charged or credited to earnings is affected by subsequent
changes in the market value of these derivatives.

There were no material amounts of options, swaps or contracts outstanding at
August 31, 1995 and 1994.

NYMEX-traded futures and option contracts are guaranteed by NYMEX and have
nominal credit risk. All other derivative transactions expose the Company to
off-balance sheet risk in the event of non-performance by the counterparts. In
order to minimize this risk, the Company analyzes each counterparts financial
condition prior to entering into an agreement, establishes credit limits and
monitors the appropriateness of these limits on an on-going basis. Swap
agreements are generally settled at the expiration of the contract term and may
be subject to margin requirements with the counterparty. NYMEX traded futures
and options contracts require daily cash settlement in margin accounts with
brokers.

(J)  COMMITMENTS AND CONTINGENCIES

LEASES - The initial lease term on the Company's headquarters building, ONEOK
Plaza, is for 25 years, expiring in 2009, with six five-year renewal options.
At the end of the initial term or any renewal period, the Company can purchase
the property at its fair market value. Rent for the lease accrues annually at
$6.8 million a year until 2009. Rent payments were $5.8 million for 1996, 1995,
and 1994. Estimated future minimum rental payments for the lease are $5.8
million for each of the years ended August 31, 1997 through 1999, $7.6 million
for the year ended August 31, 2000, $9.3 million for each of the years ended
August 31, 2001 through 2009.

The Company emphasizes that the volumes of reserves shown above are estimates,
which, by their nature, are subject to later revision. The estimates are made
by the Company's petroleum engineers and geologists utilizing all available
geological and reservoir data as well as production performance data. These
estimates are reviewed annually and revised, either upward or downward, as
warranted by additional performance data.


(M)  DISCOUNTED FUTURE NET CASH FLOWS (UNAUDITED)

Estimates of the standard measure of discounted future cash flows from proved
reserves of oil and natural gas shown in the accompanying table are based on
prices at the end of the year. Gas prices are escalated only for fixed and
determinable amounts under provisions of applicable regulations in some
contracts. These estimated future cash flows are reduced by estimated future
development and production costs based on year-end cost levels, assuming
continuation of existing economic conditions, and by estimated future income
tax expense. This tax expense is calculated by applying the current year-end
statutory tax rates to pretax net cash flows (net of tax depreciation,
depletion, and lease amortization allowances) applicable to oil and gas
production.

OTHER MATTERS

For the purpose of complying with the amendments to the rules governing Form
S-8 (effective July 13, 1990) under the Securities Act of 1933, the undersigned
registrant hereby undertakes as follows, which undertaking shall be
incorporated by reference in registrant's Registration Statements on Form S-8,
Registration Nos. 33-04177 (filed May 21, 1996), 33-04179 (filed May 21, 1996),
and 33-06857 (filed June 26, 1996):

     Insofar as indemnification for liabilities arising under the Securities
     Act of 1933 may be permitted to directors, officers, and controlling
     persons of the registrant pursuant to the foregoing provisions, or
     otherwise, the registrant has been advised that in the opinion of the
     Securities and Exchange Commission such indemnification is against public
     policy as expressed in the Act and is, therefore, unenforceable. In the
     event that a claim for indemnification against such liabilities (other
     than the payment by the registrant of expenses incurred or paid by a
     director, officer, or controlling person of the registrant in the
     successful defense of any action, suit, or proceeding) is asserted by such
     director, officer, or controlling person in connection with the securities
     being registered, the registrant will, unless in the opinion of its
     Counsel the matter has been settled by a controlling precedent, submit to
     a court of appropriate jurisdiction the question whether such
     indemnification by it is against public policy as expressed by the Act and
     will be governed by the final adjudication of such issue.

         5.  Miscellaneous.

             5.1 Purchasing and Selling of Commitments and Loans. On the date
of this Third Amendment, certain Banks (the "Buying Banks") hereby agree to
purchase without recourse, and certain Banks (the "Selling Banks") hereby agree
to sell without recourse, such an interest in the Aggregate Commitment and the

Commitment and Loans indicated on Schedule 1.1 hereto.

             Each Selling Bank represents and warrants to each Buying Bank that
it is the legal and beneficial owner of the Commitment and Loans being assigned
by it and that the same are free and clear of any adverse claim. Other than as
provided above, no Selling Bank makes any representation or warranty and
assumes no responsibility with respect to the Commitments, the Loans, this

financial condition of the Company, or the performance or observance by the
Company hereunder. The Company agrees to pay on demand directly to any Selling

Bank in respect of any portion of its Loans being assigned hereunder. The
Company and the Agent hereby consent to such assignments.

as hereby expressly amended, the Agreement and each other Loan Document shall
each remain in full force and effect, and are hereby ratified and confirmed in
all respects on and as of the date hereof.

             5.3 Waivers. This Third Amendment is limited solely to the matters
expressly set forth herein and is specific in time and in intent and does not
constitute, nor should it be construed as, a waiver or amendment of any other
term or condition, right, power or privilege under the Agreement, the Loan
Documents, or under any agreement, contract, indenture, document or instrument
mentioned therein; nor does it preclude or prejudice any rights of the Agent or
the Banks thereunder, or any exercise thereof or the exercise of any other
right, power or privilege, nor shall it require the Requisite Banks to agree to
an amendment, waiver or consent for a similar transaction or on a future
occasion, nor shall any future waiver of any right, power, privilege or default
hereunder, or under any agreement, contract, indenture, document or instrument
mentioned in the Agreement, constitute a waiver of any other default of the
same or of any other term or provision.

             5.4 Counterparts. This Third Amendment may be executed in any
number of counterparts and all of such counterparts taken together shall be
deemed to constitute one and the same instrument. This Third Amendment shall
