ITEM 1.  BUSINESS

    Aquila Gas Pipeline Corporation (the Company) is engaged in the business of
purchasing, gathering, processing, transporting and marketing natural gas and
natural gas liquids (NGLs).  The Company, through its direct and indirect
subsidiaries, owns and/or operates an interest in thirteen natural gas
gathering systems and four natural gas processing plants in Texas and Oklahoma.
In addition, the Company currently owns a 40% interest in Oasis Pipe Line
Company (Oasis) which owns an intrastate pipeline system that connects the
Waha, Texas hub to major marketing pipelines at the Katy, Texas hub.  The
Company provides essential services to natural gas producers by connecting
producers' wells to the Company's gathering systems, compressing and treating
the natural gas, gathering the natural gas for delivery to its processing
plants, processing the gas to remove NGLs and providing access for the natural
gas and NGLs to various markets.  The Company ranks as one of the leading
independent producers of NGLs in the United States.  In addition, the Company
purchases, markets and arranges for delivery of natural gas outside of its
pipeline systems.

    Substantially all of the Company's revenues are attributable to sales of
natural gas and NGLs.  These sales occur on the Company's facilities as well as
on third party gathering and transport lines (off-system).  The Company
performs three functions that add value to the natural gas stream received at
the wellhead and enable the Company to realize a profit upon such sales.
First, the Company provides gathering, compression and treatment services prior
to delivery of the natural gas to processing facilities or transport pipelines.
Second, the Company processes natural gas at its processing facilities, thereby
separating the stream into NGLs and residue gas which can generally be sold
separately for a greater combined price than the price of natural gas from the
wellhead.  Third, the Company purchases natural gas from producers in the field
and other gas marketing companies and sells natural gas and NGLs to large
volume customers, of which off-system sales represents 52% of the Company's
operating revenues in 1996.  The Company also transports third party natural
gas for a fee, which presently represents less than 1% of operating revenues.

    The Company's principal assets are located in major gas producing areas in
southeast Texas and western Oklahoma.  The Company's Southeast Texas Pipeline
System (the SETPS) is located in the Austin Chalk trend in southeast Texas and
consists of approximately 2,222 miles of pipe with total gross gas throughput
capacity of approximately 710 million cubic feet per day  (MMcf/d).  The
Company's western Oklahoma pipeline systems, located in the Anadarko Basin,
consist of approximately 485 miles of pipe with total gross gas throughput
capacity of approximately 155 MMcf/d.  The Company has several other gathering
systems located in East, West and South Texas totaling approximately 709 miles
of pipe with total gas throughput capacity of approximately 518 MMcf/d.

    The Company's LaGrange, Texas natural gas processing plant, which is 
connected to the SETPS, is one of the largest NGLs producing facilities in the
United States with a gas throughput capacity of approximately 230 MMcf/d.  The
Company also has an interest in three  additional natural gas processing plants
with gas throughput capacity aggregating 268 MMcf/d.

    The Company's principal executive offices are located at One International
Centre, 100 N.E. Loop 410, Suite 1000, San Antonio, Texas, 78216.

GENERAL DEVELOPMENT OF BUSINESS

    The Company, a Delaware corporation, is a majority-owned  subsidiary of
Aquila Energy Corporation (Aquila Energy), which is principally a natural gas
marketing company.  Aquila Energy was formed in 1985 by UtiliCorp United Inc.
(UtiliCorp), a New York Stock Exchange energy and services company, to take
advantage of natural gas marketing and transportation opportunities created by
the deregulation of the natural gas industry.  The Company was founded in 1989
under the name of Aquila Gas Systems to acquire natural gas gathering and
processing assets which would support the natural gas production and marketing
activities of Aquila Energy.  In  1993, the Company sold 5.4 million shares of
common stock to the public in an initial public offering.  Aquila Energy
currently owns approximately 82% of the common stock outstanding.

    Since its formation, the Company's primary objective has been to achieve
growth in cash flow and earnings by increasing the volume of gas that it
gathers, processes, transports and markets through internal project development
and acquisitions.  Set forth below is information regarding significant
acquisitions or construction projects, during the last three years, at a total
cost, including liabilities assumed, of approximately $194.4 million.

(a) Additions to the SETPS.

    OASIS PIPE LINE COMPANY

    In July and November 1996, the Company acquired 15% and 25%, respectively,
of the outstanding capital stock of Oasis and related transportation rights
from Dow Hydrocarbons and Resources Inc. (DHRI).  The Company can deliver and
receive natural gas at various points along the Oasis Pipeline.  The
transportation rights currently amount to 320 MMcf/d of firm intrastate
transportation between the Waha, Texas hub and the Katy, Texas hub, plus the
opportunity to utilize excess capacity on an interruptible basis.  The acquired
transportation rights are utilized by the Company to conduct additional natural
gas marketing activities not otherwise available to the Company.

    The Oasis Pipeline system consists of an approximately 600-mile pipeline
system and related mainline compression which connects the Waha, Texas hub
located in the Permian Basin producing area of West Texas to major marketing
pipelines at the Katy, Texas hub near Houston, Texas.  Oasis has a nominal one
(1) billion cubic feet per day (Bcf/d) of throughput capacity to move gas
between West Texas and the Katy, Texas hub.  Oasis' Pipeline is in proximity to
many of the Company's existing gathering systems.

    The Company, in connection with the November 1996 acquisition of Oasis,
entered into an option arrangement with El Paso Natural Gas Company (El Paso)
whereby the Company, under certain circumstances, may be required to sell to El
Paso 5% of all the capital stock of Oasis and the related transportation
rights.  The sales price is $16.8 million, subject to certain adjustments.

    On January 31, 1997, the Company received notice from El Paso of its intent
to exercise the option arrangement.  If consummated (expected close date is
April 1, 1997), the Company would own 35% of the capital stock of Oasis and
would have 280 MMcf/d of firm intrastate transportation capacity.

    SOUTHERN EXTENSION

    In December 1995, the Company completed the Southern Extension, a 25-mile
24-inch diameter pipeline, which connects the Company's gas gathering
facilities in Grimes and Washington Counties, Texas to the Company's Katy
Pipeline.  The Southern Extension provides 225 MMcf/d of additional gas
gathering capacity.

    KATY PIPELINE

    In August 1995, the Company completed the construction of a 55-mile 30-inch
diameter pipeline which connects the SETPS to Exxon Company, U.S.A.'s (Exxon)
gas processing complex at Katy, Texas (the Katy Pipeline) for processing of the
Company's natural gas.  The Katy Pipeline provides approximately 450 MMcf/d of
additional throughput capacity as well as additional processing at Exxon's gas
processing plant of 275 MMcf/d.

    TRISTAR GAS COMPANY

    In January 1995, the Company acquired Tristar Gas Company (Tristar), which
owns two natural gas storage facilities and markets natural gas in the
intrastate Texas market.  Through its ownership interests in four joint
ventures, it markets natural gas in the western and mid-continent interstate
markets, and gathers, treats, processes and markets natural gas in West and
South Texas.

GATHERING AND PROCESSING

    The Company's gas gathering and processing activities include locating and
contracting to purchase natural gas supplies, operating and maintaining a
system of gathering pipelines that connect these gas supplies to transport
lines and natural gas processing plants, and operating and maintaining
processing plants linked to its gathering systems.

    PURCHASING

    The natural gas supplied  to the Company's gathering systems are generally
purchased under individually negotiated long-term contracts.  The Company
purchases substantially all of its gas supplies pursuant to contracts that
require producers to commit or dedicate all gas produced from designated
properties.  The contracts vary, however, based upon pricing provisions and
whether the contract includes gas processing provisions.

    Generally, the contract price may be a specified percentage of the
Company's resale price or other reference price (percentage-of-proceeds
contract) or may be a fixed price per million British thermal units (MMBtu)
that does not vary with the resale price obtained by the Company (fixed price
contract).  Most new contracts are percentage-of-proceeds contracts.  Under
percentage-of-proceeds contracts, the producer shares the risk of price
fluctuations.  Contracts under which the Company purchases a majority of its
gas include provisions that permit the Company to reduce the purchase price
paid for gas based on market conditions.

    The Company's gas purchase contracts may be further classified as either
processing contracts or wellhead purchase contracts. Generally, the Company
seeks contracts which have processing provisions in those areas where the
Company operates gas processing plants.  Under processing contracts, the
Company agrees to gather and process raw gas from the wells on behalf of the
producers and to allocate the NGLs recovered and the residue gas to each well
connected to its gathering system.  The Company retains a percentage of the
value of the NGLs and residue gas extracted and delivered to customers.  The
producer bears most of the cost of NGLs extracted in return for a share of NGLs
revenue.  The Company also pays either a fixed price or the applicable
percentage-of-proceeds upon sale of residue gas, depending on the form of the
contract.

    Under a wellhead purchase contract the Company pays for gas measured at the
wellhead generally at market related prices.  The Company then gathers and
delivers the gas to transmission lines for resale at a higher price or
processes the gas for its own account at its processing facilities and derives
a gross margin equal to the difference between sales proceeds of both the NGLs
and the residue gas and the cost of the natural gas purchased at the wellhead.

    In addition to revenue from the sale of NGLs and natural gas, the Company
customarily receives additional fees for compression and treatment services if
a producer's gas does not meet contract specifications.

    Certain of the Company's purchase contracts have take-or-pay or minimum
take provisions.  Historically, such contracts have not had any material
adverse effect on the Company because the Company has requested and taken all
required natural gas and the contract  price has not prevented such natural gas
from being marketed.  As a result, the Company believes that its contracts with
take-or-pay or minimum take provisions will not have a material adverse effect
on the Company.

    SUPPLY

    The performance of the Company depends upon its ability to contract for
additional gas supply.  The SETPS has, generally, experienced increased gas
throughput since mid-1990 primarily as the result of the application of
horizontal drilling technology in the Giddings Field of the Austin Chalk trend.
The Company believes this new technology has significantly increased the
economically recoverable reserves within the Austin Chalk trend and the number
of possible drilling locations that could provide natural gas supplies to the
Company.  Certain exploitation possibilities may also exist for additional
production within the Austin Chalk trend from existing or new well bores in the
areas that were previously developed using vertical well bores.  In addition,
exploration and development opportunities may exist for recompletion of
existing vertical and horizontal wells or drilling new wells into the Taylor,
Wilcox, Buda, Georgetown and Edwards formations, each of which has been proven
to be productive in certain areas served by the SETPS.

    The Company expects to be able to continue to add well connections to the
SETPS and to maintain or increase the SETPS throughput in the foreseeable
future.  The number of new wells being drilled and, therefore, the
opportunities for the Company to connect new wells to its system will be
dependent upon, among other things, the prices of crude oil and natural gas.

    PROCESSING

    The Company is one of the largest independent producers of NGLs in the
United States.  The Company owns and/or operates an interest in four natural
gas processing plants, each of which is associated with a pipeline gathering
system of the Company.  Additionally, the Company has access to process
significant volumes of natural gas at a third-party plant, described below.
The processing plants complement the Company's gathering operations by enabling
the Company to offer directly to producers the option of wellhead purchase or
processing contracts.  The sale of NGLs contributes materially to the overall
earnings of the Company because of the added value from NGLs extraction.  In
addition, gas processing supplements and diversifies the earnings derived from
natural gas sales.

    The Company's gas processing plants are modern plants with efficient liquid
recovery processes.  The plants generally operate at high production levels
which the Company believes result in low operating costs per barrel produced.
Plant locations provide access to nearby markets for the sale of NGLs, thus
reducing transportation costs.  The Company believes its processing plants
provide it with a significant competitive advantage in the acquisition of gas
supplies.  Most of the Company's gas volume processing capacity has ethane
rejection capability, which allows the Company to optimize margins during
periods when NGLs prices decline significantly relative to gas prices.

    The Company has a long-term contract to process natural gas at Exxon's
natural gas processing plant at Katy, Texas.  Deliveries of gas to the plant
began in August 1995 upon the completion of the Katy Pipeline.  This long-term
contract allows  the Company to process up to 275 MMcf/d at the Katy plant.
The Company has substantially increased its NGLs production due to this
long-term contract.

SALES AND MARKETING

    Substantially all of the Company's revenue is derived from sales of natural
gas and NGLs.  In addition to such revenue, the Company customarily receives
additional fees for compression and treatment services if a producer's gas does
not meet contract specifications, as well as transportation arrangements
whereby the Company transports third party natural gas for a fee.

    NATURAL GAS

    The Company sells natural gas to numerous utility, industrial, and pipeline
customers.  The majority of the sales of natural gas are based on spot market
prices for the month in which the gas is sold.  These sales range in length
from one day to over a year.  The long-term contracts normally contain a
premium to spot pricing.





                                       4
<PAGE>   7
    The Company has three material fixed price natural gas sales contracts, of
which two expire in 1997 and one in 1999.  With the use of appropriate
financial instruments each of the three contracts are hedged against movement
in natural gas commodity prices.  The three contracts accounted for
approximately 3% of the Company's total natural gas revenues in 1996.

    In July 1996, the Company and DHRI entered into a long-term gas supply
agreement whereby the Company will supply DHRI with a 100 MMcf/d of gas in the
Katy, Texas area at prevailing market rates.  Natural gas sales to DHRI in 1996
accounted for approximately 10% of the Company's total natural gas revenues.

    The Company has multiple delivery connections at most of its gas gathering
systems, which it believes allow it to negotiate favorable spot sales contracts
and avoid curtailments of gas deliveries.  For example, the SETPS is directly
connected to five major intrastate systems (which includes the Oasis Pipeline)
and one utility customer.  Through the Katy Pipeline and Oasis Pipeline, the
Company is directly connected to one of the largest natural gas hubs in the
state of Texas with access to most intrastate as well as interstate pipeline
systems.  Due to the flexibility derived from multiple delivery points, the
Company believes that the loss of any one of its principal customers would not
have a material adverse effect on the Company.

    The Company has significant  purchases of natural gas and sales of natural
gas and NGLs outside its own gathering and transport lines (off-system).  These
off-system marketing activities, which include the Oasis off-system marketing
activities, contributed $414.4 million of operating revenues and gross margin
of $18.1 million to the Company in 1996, and also assisted the Company in
avoiding the curtailment of gas deliveries from its gathering systems and
avoiding the curtailment of firm markets during periods of production
fluctuations on the systems.  In addition, such activities provide the Company
with access to new markets and suppliers from which valuable market information
is obtained regarding possible new gathering systems and acquisition
opportunities.

    The Company, as part of its acquisition of the capital stock of Oasis,
acquired transportation rights on the Oasis Pipeline which amount to 320 MMcf/d
of firm intrastate transportation between the Waha, Texas hub and Katy, Texas
hub, plus the opportunity to utilize excess capacity on an interruptible basis.
The Company can deliver and receive gas at various points along the Oasis
Pipeline.  The acquired transportation rights allow the Company to conduct
additional off-system marketing activities not otherwise available to the
Company.  Since the acquisition, the off-system marketing activities from the
Oasis assets contributed $112.8 million in operating revenues.

    Natural gas is sold primarily for electric power generation and for end-use
as a heating fuel for homes and industry.  A majority of the Company's natural
gas sales occur in the Texas intrastate market.  Volumes of natural gas sold
are not typically seasonal; however, natural gas sales prices have historically
been higher in the winter months.

    The Company generally attempts to match its gas purchases and sales
transactions.  However, when appropriate, the Company uses financial
instruments such as futures and options to hedge the risk associated with
fluctuating natural gas prices.  See Note 9 of Notes to Consolidated Financial
Statements.

    NGLS MARKETING

    The Company sells NGLs to various petrochemical firms, refiners and
marketers.  With the completion of the Katy Pipeline in August 1995, the
Company entered into a long-term contract to sell a significant portion of the
Company's NGLs to Exxon.  In 1996, Exxon accounted for approximately 26% of the
Company's gross NGLs production.  The Company sold its remaining NGLs to
various parties under short-term contracts generally at a spot index based
price.

    Prices for certain NGLs closely follow crude oil related products.  Gas
processing increases the value of throughput when natural gas prices are low in
relation to NGLs prices.  The sale of NGLs contributes materially to the
overall profitability of the Company and reduces its dependence on natural gas
sales and related margins.

    In 1996, the Company entered into financial instruments such as swaps and
forward contracts to hedge the risk associated with fluctuating NGLs prices.
See Note 9 of Notes to Consolidated Financial Statements.

    NGLs are typically used as petrochemical feedstocks, petroleum refinery
blendstocks or fuel.  Petrochemical plants use ethane, propane, normal butane,
and natural gasoline as feedstocks in the production of ethylene, which has
widespread applications in the production of plastics and plastic products,
building materials, automobile antifreeze and other products.  Refineries
enhance the vapor pressure of gasoline in order to improve cold weather
starting of automobile motors with normal butane and iso-butane as a motor fuel
additive after further processing.  Propane is used as fuel for home heating
and cooking, industrial heaters and boilers, vehicles, and  agricultural
applications.





                                       5
<PAGE>   8
    As feedstock, demand for NGLs is influenced by the demand for the end
products in which they are used.  For example, a number of petrochemical
producers have recently added significant new production capacity for ethylene
along the Gulf Coast.  The Company anticipates that this development will
increase demand for NGLs in the Mont Belvieu, Texas market, which is the
central delivery point for the Gulf Coast petrochemical industry.  Also, the
demand for normal butane and iso-butane, which are important feedstocks in the
production of methyl tertiary butyl ether (MTBE) (an oxygenate), is expected to
increase as demand for MTBE in gasoline production increases.  The required use
of oxygenates in motor gasoline under the Clean Air Act Amendments of 1990 in
many parts of the United States is expected to increase demand for MTBE.
Seasonal requirements of purchasers using NGLs as a fuel source also affect
demand.  NGLs production is dependent upon the supply and NGLs content of
domestic natural gas.  The market price of NGLs relative to natural gas affects
the volume of natural gas processed and the NGLs extracted from the natural
gas.  Certain NGLs are produced outside North America and imported by ship,
which has an effect on NGLs prices from time to time.

COMPETITION

    The Company operates in a highly competitive environment.  The Company
competes in the gathering, processing, marketing and transport business for
supplies of natural gas.  Many of the Company's competitors have greater
financial and other resources than the Company.  Competition for gas supplies
is primarily based on price, service and the availability of facilities.  The
Company believes that its competitive advantages include (i) management
expertise in gas purchasing and marketing, (ii) its ability to connect wells
promptly and efficiently operate pipelines, (iii) its ability to ensure
reliable gas deliveries, and (iv) favorable supplier and market relationships.

    There is intense competition in the marketing of natural gas and NGLs.  The
Company has numerous competitors, including marketing affiliates of intrastate
and interstate pipelines, the major integrated oil companies and intrastate and
interstate pipelines and other gas gatherers, gas processors and marketers of
widely varying sizes, financial resources, experience and supplies of gas.
Distributors of gas (some of whom are customers of the Company) are, in some
cases, engaged directly and through affiliates, in marketing activities that
compete with those of the Company.

GOVERNMENTAL REGULATION

    Currently, Federal, state and local regulations do not materially affect
the purchase and sale of gas and the fees received for gathering and processing
by the Company.  Therefore, except as constrained by competitive factors and
contracts, the Company has considerable pricing flexibility.  However, Federal,
state and local laws and regulations, directly or indirectly, govern some
aspects of the operations  of the Company.  These laws and regulations may in
the future have a significant impact upon the Company's overall operations.

    Certain activities of the Company are subject to regulation by the Railroad
Commission of Texas (RRC) pursuant to its jurisdiction over common purchasers
and natural gas utilities.  Certain subsidiaries of the Company are subject to
the common purchaser statutes and regulations and the regulations as an
intrastate gas utility.

    The RRC has authority to regulate the volumes of natural gas purchased by
common purchasers and the rates charged for the intrastate transportation and
sale to natural gas utilities in Texas.  Under the Gas Utility Regulatory Act
and other Texas statutes, the RRC has the duty to ensure that rates for the
transportation and sale of natural gas are just and reasonable and that gas
utilities are prohibited from charging rates that are unreasonably
preferential, prejudicial or discriminatory.  The Company believes that its RRC
jurisdictional activities and tariffs are in compliance with applicable laws
and regulations.

    All of the Company's pipeline operations are subject to Federal safety
standards promulgated by the Department of Transportation under applicable
Federal pipeline safety legislation, as supplemented by various state safety
statutes and regulations.

    Rates for gas transported for interstate commerce on the Mooreland System
in Oklahoma and the Brooks-Hidalgo System in Texas  are regulated by the
Federal Energy Regulatory Commission (FERC) under Section 311 of the Natural
Gas Policy Act (NGPA).





                                       6
<PAGE>   9
    The Company's Oklahoma operations are subject to regulation by the State of
Oklahoma.  The majority of these regulations are administered by the Oklahoma
Corporation Commission (OCC).  Any entity engaged in the business of carrying
or transporting natural gas by pipeline is declared to be a common carrier
under Oklahoma law and is prohibited from any unjust or unlawful discrimination
in the carriage, transportation or delivery of gas.  Although Oklahoma law may
be sufficiently broad to permit the OCC to set rates and terms of service for
the transportation and delivery of natural gas involving the Company's Oklahoma
assets, the OCC has not done so to date.  There can be no assurance that the
OCC will not do so in the future.  Recent Oklahoma legislation prohibits
entities which engage in gathering gas from charging any fee which is unjustly
or unlawfully discriminatory.  The Company does not expect this legislation to
have any significant impact on the Company's operations.

    An entity carrying or transporting natural gas by pipeline which is engaged
in the business of purchasing natural gas is declared to be a common purchaser
under Oklahoma law and is required to purchase, without discrimination in favor
of persons or price, all natural gas in the vicinity of its lines.  Ratable
purchase is required if a purchaser is unable to purchase all gas offered.  To
date, such legislation has not had any significant effect on the Company's
Oklahoma operations.

    The OCC regulates the amount of gas which producers can sell or deliver to
the Company.  Currently, substantially all gas received by the Company in its
Oklahoma operations is produced from wells for which the OCC establishes
allowable production rates at quarterly hearings based upon the OCC's
determination of the market demand.

ENVIRONMENTAL

    The Company's operations are subject to numerous laws and regulations
relating to the protection of the environment or the discharge of materials
into the environment which are administered by Federal and state regulatory
agencies, including the Federal Environmental Protection Agency (EPA), the
Texas Natural Resources Conservation Commission and the Oklahoma Department of
Environmental Quality.  Currently, there are no existing or pending actions,
suits or proceedings relating to any environmental laws or regulations and all
material notices, permits and similar authorizations required to be obtained or
filed to operate the business have been duly obtained or filed.

   The Company believes that it is in substantial compliance with environmental
laws and regulations and that such laws and regulations do not pose a burden on
the operations of the Company dissimilar to that placed on its competitors.
Such laws and regulations could impose significant liability on the Company for
damages, cleanup costs and penalties in the event of certain discharges into
the environment.  In addition, product sales and markets may be affected by
such laws and regulations.  Such laws and regulations have generally become
more stringent in recent years, often imposing greater liability on a larger
number of parties.  Because the requirements imposed by such laws and
regulations frequently change, the Company is unable to predict the ultimate
costs of compliance with such requirements or whether the incurrence of such
costs would have a material adverse effect on the operations of the Company.

INSURANCE AND OPERATIONAL RISKS

    The Company is subject to various hazards which are inherent in the
industry in which it operates such as explosions, product spills, leaks and
fires, each of which could cause personal injury and loss of life, severe
damage to and destruction of property and equipment, and pollution or other
environmental damage, and may result in curtailment or suspension of operations
at the affected facility.  The Company maintains physical damage, comprehensive
general liability, workers' compensation and business interruption insurance.
Such insurance is subject to deductibles that the Company considers reasonable.
The Company is not fully insured against all risks in its business; however,
the Company believes that the coverage it maintains is adequate and consistent
with other companies in the industry.  Consistent with insurance coverage
typically available to the natural gas industry, the Company's insurance
policies do not provide coverage for losses or liabilities relating to
pollution, except for sudden and accidental occurrences.

EMPLOYEES

    At December 31, 1996, the Company had 308 employees.  None of the Company's
employees is a party to a collective bargaining agreement.

ITEM 3.  LEGAL PROCEEDINGS

LITIGATION:

             In 1987, HECI Exploration, Inc. (HECI) instituted a suit in the
    155th Judicial District Court, Fayette County, Texas against the Company
    alleging various breaches of a take-or-pay contract and seeking
    approximately $3.0 million in damages.  The Company's motion for summary
    judgment was granted by the lower court.  A Texas appellate court, however,
    has remanded the case for trial.

             In the purchase and sale agreement executed in connection with the
    1987 acquisition of Clajon Gas Company by a predecessor of the Company,
    Clayton Williams, Jr., individually, and certain selling entities agreed to
    jointly and severally indemnify the purchaser from liabilities related to
    the conduct of the acquired business or arising out of any assigned
    contracts prior to the closing date of the acquisition, subject to certain
    limitations.  Thus, certain claims and litigation, including the HECI
    litigation described above, involving the acquired business and contracts
    assigned to the Company are subject to these indemnification provisions.
    The indemnity provision limits Mr. Williams' personal liability to $3.0
    million in the aggregate.

             In August 1995, Mr. Charles Menke instituted suit against the
    Company in the 155th Judicial District Court, Waller County, Texas,
    alleging  the Company has constructed and was operating a pipeline on
    property owned by Mr.  Menke.  Mr. Menke alleges the Company is a
    trespasser on his property and seeks unspecified damages for such trespass
    including punitive damages.  Mr. Menke additionally seeks an injunction
    requiring the Company to cease operation of its pipeline and to remove such
    line from his property.  In October 1995, the Court denied Mr. Menke's
    request for a temporary injunction and set this matter for trial on January
    15, 1996.  By consent of all parties the January 15, 1996 trial date was
    postponed and no new trial date has been set.  The Company believes Mr.
    Menke's claims for injunctive relief are without merit, and believes it has
    meritorious defenses to the damage claims. The Company has filed a denial
    of all claims and is actively pursuing its defense of this litigation.

TAXES:

             The Internal Revenue Service (IRS) has examined and proposed
    adjustments to UtiliCorp's consolidated Federal income tax returns for 1988
    through 1991.  The  proposed adjustment affecting the Company is to
    lengthen the depreciable life of certain pipeline assets owned by the
    Company.  Presently, no final resolution of the proposed adjustment has
    been reached with the IRS.  The Company intends to vigorously contest the
    proposed adjustment and believes it is reasonably possible it will prevail.
    It is expected that additional assessments for the years 1992 through 1996
    would be made on the same issue.  Under the provisions of the tax sharing
    agreement with Aquila Energy and UtiliCorp, as discussed in Note 1 of Notes
    to Consolidated Financial Statements, the Company would be liable to
    UtiliCorp for additional taxes of approximately $11.6 million for the audit
    period and through 1996 plus potential interest of approximately $2.2
    million on the contested proposed adjustment.  The additional taxes would
    result in an adjustment to the deferred tax liability with no effect on net
    income, while any payment of interest would affect net income.  The Company
    expects that the ultimate  resolution of this matter will not have a
    material adverse effect on its financial position.

    The Company is also a party to additional claims and is involved in various
other litigation and administrative proceedings arising in the normal course of
business.  The Company believes it is unlikely that the final outcome of any of
the claims, litigation or proceedings discussed above to which the Company is a
party would have a material adverse effect on the Company's financial position
or results of operations. However, due to the inherent uncertainty of
litigation, there can be no assurance that the resolution of any particular
claim or proceeding would not have an adverse effect on the Company's results
of operations for the fiscal period in which such resolution occurred.

ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

    There were no matters submitted to a vote of security holders in the fourth
quarter of 1996.

     On March 3, 1997, the last reported sales price for the common stock, as
reported on the NYSE Composite Tape, was $13 5/8 and the Company had 143
stockholders of record and approximately 1,600 beneficial owners.

     On  February 13, 1997, the Board of Directors of the Company declared the
quarterly common stock dividend payable on March 14, 1997, to shareholders of
record on February 26, 1997.  The majority of the Company's earnings are
generated by Aquila Southwest Energy Corporation (Aquila Southwest) a
wholly-owned subsidiary.  The amount available for the payment of dividends to
the Company by Aquila Southwest under the financial covenants contained in the
indenture governing the 8.29% Senior Notes due 2002 (8.29% Senior Notes) was
approximately $48.0 million as of December 31, 1996.  These covenants provide
that no dividends may be paid by Aquila Southwest unless (i) there are no
existing defaults under the indenture, (ii) Aquila Southwest's ratio of
consolidated debt to consolidated capitalization does not exceed .55 to 1.0
through December 31, 1995 and thereafter, (iii) the pro forma fixed charges
coverage ratio is not less than 1.5 to 1.0, and (iv) the aggregate dividend
payment does not exceed the sum of (a) 50% of consolidated net income from July
1, 1992 through December 31, 1995, plus (b) increasing percentages of net
income subsequent to December 31, 1995, plus (c) the net cash proceeds from the
sale of Aquila Southwest stock after June 30, 1992, plus (d) the net cash
proceeds from the conversion of any convertible debt securities.  Accordingly,
there can be no assurance that dividends will be paid by the Company in the
future.

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

RECENT OPERATIONS DEVELOPMENTS

           On July 1, 1996 and November 1, 1996, the Company completed the
    acquisition of 15% and 25%, respectively, of the outstanding capital stock
    of Oasis and related transportation rights from DHRI for a purchase price of
    $47.1 and $84.0 million, respectively (hereinafter referred to as the "Oasis
    Acquisition").  Also, see Note 8 of Notes to Consolidated Financial
    Statements. The acquired transportation rights are utilized by the Company
    to conduct additional natural gas marketing activities not otherwise
    available to the Company (hereinafter referred to as "Oasis Marketing"). 
    The Company primarily funded the Oasis Acquisition utilizing its existing
    revolving credit agreements, as amended.

     The following discussion and analysis relates to the consolidated
financial position and results of operations of the Company for the three years
ended December 31, 1996.  Reference should be made to the Consolidated
Financial Statements and the Notes thereto.

RESULTS OF OPERATIONS

   The Company's results of operations are determined primarily by the volume
of gas purchased, processed and resold in its gas gathering systems and natural
gas processing plants, as well as its off-system marketing activities.
Fluctuations in the price levels of natural gas and NGLs also affect results of
operations since the Company generally receives a portion of the natural gas
and NGLs revenue from natural gas throughput.  Most of the Company's operating
costs do not vary directly with volumes on existing systems; thus, increases or
decreases in volumes on existing systems generally have a direct effect on net
income.

   The Company, from time to time, enters into hedging transactions such as
contracts for future deliveries in order to minimize the risk associated with
changes in the price of natural gas and NGLs.  The hedging program was
established to minimize variances in operating results due to fluctuating
commodity prices.  Gains and losses related to these transactions are deferred
and recognized in the results of operations when the hedged transaction occurs.
See Note 9 of Notes to Consolidated Financial Statements.

   YEARS ENDED DECEMBER 31, 1996 COMPARED TO DECEMBER 31, 1995

   Total operating revenues increased 65% to $799.3 million in 1996 compared to
$485.8 million in 1995.  Natural gas revenues increased 68% to $706.0 million
in 1996 compared to $420.7 million in 1995 due partially to the Oasis Marketing
activity, included since July 1, 1996, which contributed revenues of $112.8
million with associated marketed natural gas volumes of 101 MMcf/d.  Excluding
Oasis Marketing activity, natural gas revenues increased 41% to $593.2 million
due to a 49% increase in the average natural gas price to $2.33 per Mcf in 1996
from $1.56 per Mcf in 1995, despite a slight decrease in natural gas throughput
sold and marketed to 724 MMcf/d in 1996 from 750 MMcf/d in 1995.

   NGLs revenues increased 43% to $93.3 million in 1996 compared to $65.1
million in 1995 as the result of a 28% increase in gross NGLs production to
41,000 Bbls/d in 1996 compared to 32,000 Bbls/d in 1995 and a 25% increase in
the average NGLs price to $.35 per gal from $.28 per gal.  Increased NGLs
production at Exxon's gas processing plant at Katy, Texas and improved NGLs
recovery processes at the plants primarily accounted for the increased NGLs
production.

   Cost of sales was $664.1 million or 83% of operating revenues in 1996
compared to $387.1 million or 80% of operating revenues in 1995.  The increase
in the percentage is primarily due to the increase in off-system marketing
activities which have lower gross margin percentages.  Cost of sales increased
primarily as the result of the Oasis Marketing activity and an increase in
average natural gas price.

   Gross margin (operating revenues less cost of sales, which includes only the
direct cost of gas sold and does not include any related operating expenses)
was $135.2 million, or 17% of operating revenues, in 1996 compared to $98.7
million, or 20% of operating  revenues, in 1995.  The decrease in the
percentage is primarily due to the increase in off-system marketing activities
which have lower gross margin percentages.  The gross margin increased 37% due
to an increase in average natural gas and NGLs prices of 49% and 25%
respectively, an increase in NGLs production and an increase in the natural gas
throughput and marketed, which includes the Oasis Marketing activity.

   Operating expenses increased 7% to $23.6 million in 1996 compared to $22.0
million in 1995 primarily as a result of expanded gathering system and plant
operations and an overall increase in various costs.

   General and administrative expenses increased 26% to $19.7 million in 1996
compared to $15.6 million in 1995 primarily due to increased compensation
costs.  Portions of compensation are linked to the Company's net income and the
Company's stock price, both of which increased in 1996.

   Depreciation and amortization increased 12% to $23.7 million in 1996
compared to $21.2 million in 1995 primarily as the result of new pipeline,
property, plant and equipment additions on the SETPS and the amortization of
the transportation rights related to Oasis.

   Interest and debt expenses increased 29% to $15.7 million in 1996 compared
to $12.2 million in the 1995 period primarily as a result of increased debt
balances incurred for capital expenditures, the Oasis acquisition and the
recognition of interest associated with certain agreed-upon tax issues (further
discussed in the following paragraph).





                                       14
<PAGE>   17
   Provision in lieu of income tax expense increased 263% to $20.1 million in
1996 compared to $5.5 million in 1995 due to an increase in income before income
taxes in 1996 compared to 1995.  UtiliCorp has agreed with the IRS on certain
tax issues as a result of the IRS audits of certain UtiliCorp Federal income tax
returns (hereinafter referred to as "agreed-upon tax issues").  The Company will
be liable to UtiliCorp for approximately $3.1 million, under the provisions of
the tax sharing agreement, once UtiliCorp assesses the Company for the
agreed-upon tax issues.  The payment of the income taxes associated with the
agreed-upon tax issues will have no effect on net income, as it will be an
adjustment to the deferred tax liability, upon assessment by UtiliCorp.  Also,
see Note 4 of Notes to Consolidated Financial Statements.

   YEARS ENDED DECEMBER 31, 1995 COMPARED TO DECEMBER 31, 1994

   Total operating revenues increased 48% to $485.8 million for the year ended
December 31, 1995 compared to $328.7 million for the year ended December 31,
1994.  Natural gas revenues increased 58% to $420.7 million in 1995 compared to
$265.8 million in 1994 as a result of the acquisition of Tristar which
contributed natural gas revenues of $97.5 million with associated gas
throughput sold and marketed volumes of 197 MMcf/d.  Excluding Tristar, natural
gas revenues increased 22% to $323.2 million due to an increase in the volume
of natural gas sold and marketed to 553 MMcf/d in 1995 from 388 MMcf/d in 1994.
These were offset by a decrease in natural gas prices of 17% to $1.56 per Mcf
in 1995 from $1.87 per Mcf in 1994.  Natural gas throughput sold increased
primarily as the result of additional wells connected to the SETPS and the
completion of the Katy Pipeline.  Excluding Tristar, off-system natural gas
marketed volumes increased 36% to 175 MMcf/d in 1995 from 129 MMcf/d in 1994
due to increased marketing opportunities.

   NGLs revenues increased 4% to $65.1 million in 1995 compared to $62.9
million in 1994 as the result of a 3% increase in gross NGLs production to
32,000 Bbls/d in 1995 compared to 31,000 Bbls/d for 1994.  Average NGLs price
remained the same at $.28 per gal for both years.  The Tristar acquisition
contributed NGLs revenue of $1.2 million with gross NGLs production of less
than 1,000 Bbls/d.

   Cost of sales was $387.1 million or 80% of operating revenues in 1995
compared to $247.5 million or 75% of operating revenues in 1994.  The increase
in cost of sales is primarily due to the acquisition of Tristar which
contributed $91.6 million.  Excluding Tristar, cost of sales increased 19% to
$295.5 million or 76% of operating revenues as the result of an increase in
volume partially offset by the decline in natural gas prices.

   Gross margin (operating revenues less cost of sales, which includes only the
direct cost of gas and does not include any related operating expenses) was
$98.7 million, or 20% of operating revenues, in 1995 compared to $81.2 million,
or 25% of operating revenues, in 1994.  The decrease in percentage is primarily
due to a higher proportion of off-system gas marketed which has higher cost of
sales percentages and a higher cost of gas supply for pipeline systems.  The
increase in gross margin is partially due to the acquisition of Tristar which
contributed gross margin of $7.1 million.  Excluding the acquisition of
Tristar, gross margin increased 13% due to the natural gas throughput increases
noted above.  Offsetting this factor was diminished gross margin per Mcf due to
reduced NGLs recoveries related to natural gas delivered without being
processed for the extraction of NGLs, and reduced heating value and NGLs
content in the natural gas delivered to the Company at the wellhead.
Additionally, natural gas prices were 17% lower than in 1994.

   Operating expenses increased 17% to $22.0 million in 1995 compared to $18.8
million in 1994 primarily as a result of expanded gathering systems and plant
operations, which increased gas throughput and $1.5 million of costs related to
Tristar.

   General and administrative expenses increased 37% to $15.6 million in 1995
compared to $11.4 million in 1994 due to $1.6 million of costs related to
Tristar, increased charges under the service agreement with UtiliCorp and
Aquila Energy, and increased labor costs.

   Depreciation and amortization increased 24% to $21.2 million in 1995
compared to $17.1 million in 1994 primarily as the result of new pipeline,
property, plant and equipment additions on the SETPS and $2.0 million of
Tristar depreciation and amortization expense.

   Effective October 1, 1995, the Company adopted Statement of Financial
Accounting Standards No. 121 (SFAS 121), "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to Be Disposed Of".  SFAS 121
requires companies to review long-lived assets and certain identifiable
intangibles for impairment whenever events or changes in circumstances indicate
that the carrying amount of an asset may not be recoverable.  The Company
recorded an impairment loss of $13.2 million or $8.2 million after tax in the
fourth quarter of 1995.  See Note 1 of Notes to Consolidated Financial
Statements.





                                       15
<PAGE>   18
   Interest and debt expense increased 31% to $12.2 million in 1995 compared to
$9.3 million in 1994 primarily as a result of increased interest rates and
higher debt balances due to the acquisition of Tristar and for capital
expenditures.

   Provision in lieu of income tax expense decreased 41% to $5.5 million in
1995 compared to $9.3 million in 1994 due to a decline in income before taxes
in 1995 compared to 1994.

LIQUIDITY AND CAPITAL RESOURCES

   The Company generates significant cash from operations and expects such cash
and borrowings to be its primary source of liquidity.  The Company's primary
uses of cash consist of capital expenditures, acquisitions, working capital
requirements, dividends and debt repayment.  The Company's historical net
additions to pipeline, property, plant and equipment were $27.5 million and
$76.2 million for the years ended December 31, 1996 and 1995, respectively.  In
July 1996 and November 1996, the Company completed the 15% and 25%,
respectively, Oasis acquisitions for a cash purchase price of $47.1 million and
$84.0 million, respectively.  Capital expenditures are expected to be
approximately $34.0 million in 1997 excluding business acquisitions, if any, of
which the Company expects it can fund from operating cash flow.

   In April 1997, the Company expects to receive $16.8 million (which would be
utilized to paydown the Company's revolving debt) from El Paso upon their
exercise of certain option arrangements to acquire 5% of all the capital stock
of Oasis and related transportation rights from the Company.  The Company
expects the exercise to have no material impact on its results of operations.

   The Company maintains revolving credit agreements (the Revolvers), as
amended, of $168.0 million with Aquila Energy to provide funds for general
corporate purposes.  There was $164.3 million outstanding on the Revolvers at
December 31, 1996. The total amount available to borrow on the Revolvers was
$3.7 million at December 31, 1996.  The maturity dates on the Revolvers
automatically renew in one-year periods from each commitment period (the fourth
quarter of any given year) unless Aquila Energy gives at least a one-year
notice not to renew from the commitment period.  Currently, the maturity dates
of the Revolvers are in the fourth quarter of 1998.  The Revolvers were
utilized to fund the Oasis acquisition.

   The Company has another Loan Agreement (the Loan) with Aquila Energy for an
amount of $50.0 million, which matures in 2005, to provide funds for general
corporate purposes.  The Loan requires the Company to maintain certain
financial covenants and limits the activities of the Company in other ways.  At
December 31, 1996, $50.0 million was outstanding under the Loan and the Company
was in compliance with the covenants.

   The 8.29% Senior Notes issued by Aquila Southwest in 1992 require principal
payments of $12.5 million annually.  Such principal payments are expected to be
made from cash flow from operations and borrowings.  The 8.29% Senior Note
purchase agreement has numerous covenants which affect the Company and Aquila
Southwest.  These covenants limit the ability to make dividend payments
(currently, limited to $48.0 million) and incur debt, require maintenance of
certain financial ratios and limit the activities of Aquila Southwest in other
ways. Failure to maintain the required ratios may ultimately result in an
acceleration of payments due.  At December 31, 1996, $75.0 million was
outstanding on the Senior Notes and the Company was in compliance with the
covenants.

   The Company believes that cash generated from operations and borrowings
under the Revolvers will be adequate to fund working capital requirements, debt
service payments and planned capital expenditures.  Future acquisitions or
large capital expenditures in excess of current plans would require additional
financing that the Company expects would be available through additional debt
facilities.

NEW ACCOUNTING STANDARDS

   In June 1996, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 125 (SFAS 125), "Accounting for Transfers
and Servicing of Financial Assets and Extinguishments of Liabilities," which
establishes new accounting and reporting standards for transfers and servicing
of financial assets and extinguishments of liabilities.  SFAS 125 is effective
for transactions occurring after December 1996.  Based on information currently
known by the Company, SFAS 125 will not have a material effect on the Company's
consolidated financial statements.

   In 1995, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 123 (SFAS 123), "Accounting for Stock-Based
Compensation".  SFAS 123 was required to be adopted by the Company in 1996.
SFAS 123 provides for alternative methods for recording stock-based

FORWARD-LOOKING INFORMATION

   The Company is including the following cautionary statement to make
applicable and take advantage of the new "safe harbor" provisions of the
Private Securities Litigation Reform Act of 1995 for any forward-looking
statement made by or on behalf of, the Company.  The factors identified in this
cautionary statement are important factors (but not necessarily all of the
important factors) that could cause actual results to differ materially from
those expressed in any forward-looking statement made by, or on behalf of, the
Company.

   Where any such forward-looking statement includes a statement of the
assumptions or basis underlying such forward- looking statement, the Company
cautions that, while it believes such assumptions or basis to be reasonable and
makes them in good faith, assumed facts or basis almost always vary from actual
results, and the differences between assumed facts or basis and actual results
can be material, depending upon the circumstances.  Where, in any
forward-looking statement, the Company, or its management, expresses an
expectation or belief as to future results, such expectation or belief is
expressed in good faith and believed to have a reasonable basis, but there can
be no assurance that the statement of expectation or belief will result or be
achieved or accomplished.

   Taking into account the foregoing, the following are identified as important
factors that could cause actual results to differ materially from those
expressed in any forward-looking statement made by, or on behalf of, the
Company:

a)   The ability to increase transmission, gathering, processing, and sales
     volumes can be subject to the impact of price; drilling activity and
     success of producers; and service competition, especially due to excess
     pipeline availability.  Existing volumes are subject to depletion without
     addition of future developed gas supplies.  The ability to contract
     additional gas supplies for the existing systems also is affected by the
     available number of drilling locations in the proximity of these existing
     gas systems and the related economic reserves of these drilling locations.

b)   Growth strategies through acquisition, internal project development, and
     investments in joint ventures may face legal and regulatory delays,
     financing difficulties, competition from other acquirers and competitors,
     and other unforeseeable obstacles beyond the Company's control.

c)   Future profitability will be affected by the Company's ability to compete
     with the services and economic contractual terms offered by other energy
     enterprises which may be larger, offer more services, and possess greater
     resources.  Future profitability also will be affected by the level of
     prices of natural gas, NGLs and competitive fuels and feedstocks.

d)   Future operating results and success of business ventures may be subject
     to the effects of and changes in laws and regulations, political and
     governmental changes, inflation rates, taxes, and operating conditions.
     Also, future operating results are subject to unexpected items resulting
     from such events as, but not limited to, litigation settlements, adverse
     rulings or judgments, and unexpected environmental remediation.

e)   The Company's operations are subject to the risks incident to the
     gathering, transportation, processing and storage of natural gas and NGLs,
     such as explosions, product spills, leaks and fires, any of which could
     result in substantial losses to the Company and curtailment or suspension
     of operations at a Company facility.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS





To the Board of Directors and Stockholders of
Aquila Gas Pipeline Corporation:



We have audited the accompanying consolidated balance sheets of Aquila Gas
Pipeline Corporation (a Delaware corporation) and subsidiaries as of December
31, 1996 and 1995, and the related consolidated statements of income,
stockholders' equity and cash flows for each of the three years in the period
ended December 31, 1996. These financial statements and the schedule referred
to below are the responsibility of the Company's management. Our responsibility
is to express an opinion on these financial statements and the schedule based
on our audits.

We conducted our audits in accordance with generally accepted auditing
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 financial statements referred to above present fairly, in
all material respects, the financial position of Aquila Gas Pipeline
Corporation and subsidiaries as of December 31, 1996 and 1995, and the results
of their operations and their cash flows for each of the three years in the
period ended December 31, 1996, in conformity with generally accepted
accounting principles.

As explained in Note 1 to the consolidated financial statements, in 1995 the
Company changed its method of assessing the impairment of long-lived assets.

Our audit was made for the purpose of forming an opinion on the basic financial
statements taken as a whole. The supplemental Schedule I is presented for
purposes of complying with the Securities and Exchange Commission's rules and
is not part of the basic financial statements. The schedule has been subjected

1.    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

      BUSINESS

      Aquila Gas Pipeline Corporation owns and operates natural gas gathering
and pipeline systems and gas processing plants and is engaged in the business
of purchasing, gathering, transporting, processing, storing and marketing
natural gas and natural gas liquids (NGLs), primarily in the states of Texas
and Oklahoma.

      PRINCIPLES OF CONSOLIDATION AND BASIS OF PRESENTATION

      The accompanying consolidated financial statements include the historical
operations and accounts of Aquila Gas Pipeline Corporation and subsidiaries
(referred to herein as the Company). The Company's interests in certain
business entities similar to joint ventures are proportionately consolidated.
The Company's 40% investment in the capital stock of Oasis Pipe Line Company
(Oasis), acquired in 1996 (see Note 8), is accounted for using the equity
method of accounting, see Note 11 for additional information. All significant
intercompany transactions have been eliminated in consolidation. Certain
reclassifications have been made to conform to the 1996 presentation.

      In 1993, the Company completed an initial public offering of 5,400,000
shares of its common stock at $15 per share. As a result of the offering,
approximately 18% of the Company's common stock is held by the public while
Aquila Energy Corporation (Aquila Energy) holds the remaining 82%. Aquila
Energy is a wholly-owned subsidiary of UtiliCorp United Inc. (UtiliCorp).

      The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. The more significant areas requiring the use of estimates
relate to the fair value of financial instruments and useful lives for
depreciation and amortization. Actual results may differ from those estimates.

      The Company is subject to a number of risks inherent in the industry in
which it operates, primarily fluctuating prices and gas supply. The Company's
financial condition and results of operations will depend significantly upon
the prices received for natural gas and NGLs. These prices are subject to wide
fluctuation due to a variety of factors that are beyond the control of the
Company. In addition, the Company must continually connect new wells to its
gathering systems in order to maintain or increase throughput levels to offset
natural declines in dedicated volumes. The number of new wells drilled will
depend on a variety of factors that are beyond the control of the Company.

      STATEMENTS OF CASH FLOWS

      In order to determine net cash provided by operating activities, net
income has been adjusted by, among other things, changes in current assets and
current liabilities, excluding changes in cash and cash equivalents. The
Company's cash equivalents are all liquid, short-term investments which mature
in three months or less. The changes in operating assets and liabilities, net
of the effects of acquisitions, are as follows:

      REVENUE RECOGNITION

      Operating revenues are recognized upon the delivery of natural gas or
NGLs to the buyer of the related products or services.

      INVENTORIES AND EXCHANGES

      Inventories consist of NGL products, which are stated at the lower of cost
(determined on a first-in, first-out basis) or market value, and natural gas in
storage, which is stated at an amount not in excess of market value. Exchanges
consist of natural gas and NGL delivery imbalances which are presented net on
the accompanying consolidated balance sheets and which are stated at amounts not
in excess of market value.

      MATERIALS AND SUPPLIES

Materials and supplies are stated at the lower of cost (determined on a
first-in, first-out basis) or market.

1.    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:  (CONTINUED)

      HEDGING ACTIVITIES

      The Company enters into various financial instrument and commodity
contracts to hedge anticipated purchases and sales of natural gas and NGLs.
Such contracts are designated at inception as a hedge when there is a direct
relationship to the price risk associated with the Company's future purchases
and sales of commodities. Gains and losses related to anticipatory transactions
are deferred and recognized in income when the hedged transaction occurs.

      PIPELINE, PROPERTY, PLANT AND EQUIPMENT

      Pipeline, property, plant and equipment are stated at cost. Additions and
improvements that add to the productive capacity or extend the useful life of
the asset are capitalized. Expenditures for maintenance and repairs are charged
to expense as incurred. Upon disposition or retirement of pipeline components
or gas plant components, any gain or loss is recorded to accumulated
depreciation. When entire pipeline systems, gas plants or other property and
equipment are retired or sold, any gain or loss is included in operations.

      Depreciation of the pipeline systems, gas plants and processing equipment
is provided using the straight-line composite method rate primarily based on an
estimated useful life of 25 years. Interest cost on funds used to finance major
pipeline projects during their construction period is capitalized. Capitalized
interest cost was $173, $1,006 and $338 during 1996, 1995 and 1994,
respectively.

      Construction work in progress at December 31, 1996 and 1995 was $1,630
and $3,547, respectively.

      INTANGIBLE ASSETS

      Intangible assets are recorded at cost and are generally amortized on a
straight-line basis over their estimated useful lives. Intangible assets
consist of the following:

</TABLE>

      The transportation rights (see Note 8) have a remaining contractual life
of approximately three years. However, management of the Company believes it is
probable the transportation rights will be renegotiated with comparable terms
for a minimum of an additional 20 years.

      Amortization expense associated with intangible assets was $2,753, $2,504
and $1,188 during 1996, 1995 and 1994, respectively.

1.    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)

      INCOME TAXES

      The Company is included in the consolidated Federal income tax return
filed by UtiliCorp. Under a formal tax sharing agreement, as amended, between
the Company, Aquila Energy and UtiliCorp, the Company will pay to UtiliCorp the
amount of its current tax liability as if the Company were filing a separate
tax return for tax years in which the Company generates current taxable income.
For tax periods in which the Company generates current tax losses, the Company
will receive the benefit of such losses only to the extent it is able to offset
taxable income generated in years subsequent to the 1992 tax year. In the event
additional income taxes, penalties and interest are assessed by tax authorities
as a result of examinations, the formal tax sharing agreement provides for the
payment terms by the Company of assessed amounts.

      The Company accounts for income taxes in accordance with Statement of
Financial Accounting Standards No. 109 (SFAS 109) which requires that deferred
tax assets and liabilities be established for the basis differences between the
reported amounts of assets and liabilities for financial reporting purposes and
income tax purposes.

      EARNINGS PER SHARE

      Earnings per share of common stock were computed using the weighted
average number of common shares outstanding for each respective period. There
are no dilutive common stock equivalents outstanding for any period. The
weighted average number of common shares used in computing earnings per share
is 29,400,000 shares for 1996, 1995 and 1994, respectively.

      IMPAIRMENT OF LONG-LIVED ASSETS

      In March 1995, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 121 (SFAS 121), "Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of,"
which requires companies to assess their long-lived assets for impairment. SFAS
121 requires companies to review for impairment whenever events or changes in
circumstances indicate that the carrying amount of a long-lived asset may not
be recoverable. If the carrying amount of a company's long-lived assets is not
recoverable as assessed at the lowest level of identifiable cash flows, an
impairment loss will be recognized equal to the difference between the asset's
carrying amount and its fair value. The Company adopted SFAS 121 as of October
1, 1995. The effect of the adoption of SFAS 121 was to record an impairment
loss of $13,163, which was recorded in the Statement of Income for the year
ended December 31, 1995.

      The impairment loss was calculated as the difference between the asset
carrying amounts and their fair value as determined by projected future net
cash flows, giving consideration to prices, future potential gas supply reserve
additions and discount rates. Included in the impairment loss are several small
pipeline systems where volume decreases have occurred and current gas supply
additions are limited due to low overall industry drilling activity.

      NEW ACCOUNTING STANDARDS

      In June 1996, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 125 (SFAS 125), "Accounting for Transfers
and Servicing of Financial Assets and Extinguishments of Liabilities," which
establishes new accounting and reporting standards for transfers and servicing
of financial assets and extinguishments of liabilities. SFAS 125 is effective
for transactions occurring after December 31, 1996. Based on information
currently known by the Company, SFAS 125 will not have a material effect on the
Company's consolidated financial statements.

      In 1995, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 123 (SFAS 123), "Accounting for Stock-Based
Compensation". SFAS 123 was required to be adopted by the Company in 1996. SFAS
123 provides for alternative methods for recording stock-based compensation and
requires additional disclosure regardless of which method is utilized to record
stock-based compensation. The Company has determined that SFAS 123 does not
have an effect on the Company's current results of operations.

2.    RELATED PARTY TRANSACTIONS:

 The Company enters into various types of transactions with Oasis, Aquila
Energy and UtiliCorp. The Company sells natural gas to Aquila Energy and
subsidiaries of UtiliCorp and purchases natural gas from Aquila Energy. Aquila
Energy enters into certain natural gas and NGLs hedging transactions with or on
behalf of the Company. Additionally, the Company reimburses Aquila Energy and
UtiliCorp, based on the formal service agreement described below, for the
direct and indirect costs of certain Aquila Energy and UtiliCorp employees who
provide services to the Company and for other costs (primarily general and
administrative expenses) related to the Company's operations. Aquila Energy and
UtiliCorp allocate indirect costs to the Company using a formula based upon the
ratio of the Company's levels of revenues, net pipeline, property, plant and
equipment and number of personnel to the total consolidated Aquila Energy or
UtiliCorp levels for such factors. Management of the Company believes that the
use of such a formula results in a reasonable allocation of indirect costs.
Aquila Energy also provides the Company and its subsidiaries with financing
agreements, as described in Note 3. Additionally, the Company transports gas on
Oasis' Pipeline (see Note 8).

      The Company has formal service agreements with each of Aquila Energy and
UtiliCorp to provide various services to the Company similar to those provided
prior to the effective date of such service agreements. The agreements provide
for the Company to reimburse Aquila Energy and UtiliCorp for the actual direct
costs of providing such services and to reimburse Aquila Energy and UtiliCorp
for related indirect costs allocated to the Company on a formula basis.

and $62,809 thereafter.

      REVOLVING CREDIT AGREEMENTS

      The Company and its subsidiaries maintain credit agreements, as amended,
with Aquila Energy that provide revolving credit facilities for borrowings of
up to $165,000. As of December 31, 1996, there was $3,299 unused under the
credit agreements. The revolvers bear interest at the Company's election of
either a base rate (the higher of a bank prime rate or 1/2 of 1% above the
Federal Funds rate), an adjusted certificate of deposit rate or a Eurodollar
rate. The maturity dates of the revolvers automatically renew in one-year
periods from each commitment period (the fourth quarter of any given year)
unless Aquila Energy gives at least a one-year notice not to renew from the
commitment period. Currently, the maturity dates are in the fourth quarter of
1998. The notes are unsecured and $50,000 of the revolving credit facilities
are subordinate to the 8.29% senior notes described later. Annual commitment
fees of 1/4 of 1% on the unutilized portion of the revolving credit facilities 
are paid to Aquila Energy.

3.    DEBT:  (CONTINUED)

      The revolving credit agreements require the Company and its subsidiaries
to comply with certain restrictive covenants. At December 31, 1996, the Company
and its subsidiaries were in compliance with such covenants.

      On July 1, 1996, the Company entered into an unsecured $3,000 revolving
note agreement with Aquila Energy. The note bears interest at a bank prime rate
( 8.25% at December 31, 1996) and matures in December 1999. At December 31,
1996 the outstanding balance was $2,623, which is included in "Other" in the
previous table.

      LOAN AGREEMENT

      The Company has a loan agreement (the Loan) with Aquila Energy for an
amount of $50,000. The Loan is unsecured and bears interest at 6.47% due
semi-annually. The principal amount of the Loan shall be repaid to Aquila
Energy by June 1, 2005. The Loan contains various covenants including certain
financial covenants related to net worth. At December 31, 1996, the Company was
in compliance with such covenants.

      SENIOR NOTES

      The 8.29% senior notes (Senior Notes) are unsecured and bear interest at
8.29% due semi-annually. Principal payments of $12,500 are required each year
until final maturity in September 2002. Upon issuance of the Senior Notes the
Company deferred approximately $1,886 of initial fees and expenses and is
amortizing such deferred financing costs over the life of the notes.

      The Senior Notes contain various restrictive covenants, which among
others, limit the sale of assets, additional indebtedness of a subsidiary, and
the ability to make certain restricted payments, including restrictions on the
ability to make dividend payments for amounts in excess of those calculated in
accordance with the covenants. The Senior Notes also require a subsidiary of
the Company to maintain certain financial covenants related to cash flow, fixed
charges and net worth. At December 31, 1996, the subsidiary of the Company was
in compliance with such requirements and had the ability to pay restricted
payments of approximately $48,000.

      LINE OF CREDIT

      The Company has an agreement with a bank whereby standby letters of
credit may be issued (see Note 7) in an aggregate amount not to exceed the
lesser of $18,000 or a borrowing base as calculated monthly under the
agreement. At December 31, 1996, the borrowing base was $18,000 with no
principal outstanding. This line of credit expires June 30, 1997, and is
secured by the accounts receivable of certain subsidiaries of the Company. Any
draw under a letter of credit bears interest at the bank's prime rate plus 2%,
payable monthly.

      Components of income tax expense are as follows:

4.    INCOME TAXES: (CONTINUED)

      Income tax expense is different than the amount computed by applying the
statutory Federal income tax rate to income before taxes. The reasons for these
differences are as follows:

      The components of the net deferred tax liability of the Company are as
follows:

                                                 ========        ========
</TABLE>


      The deferred tax liabilities noted above arise primarily from the excess
of tax depreciation over book depreciation. The deferred tax assets noted above
relate primarily to alternative minimum tax (AMT) credit carryforwards and net
operating loss carryforwards (NOL). A valuation allowance is provided when it
is more likely than not that some portion of the deferred tax assets will not
be realized.

      At December 31, 1996, the Company has NOL's of approximately $2,000 which
begin to expire in 2010 and AMT credit carryforwards of approximately $22,000
which have no expiration date.

      UtiliCorp has agreed with the Internal Revenue Service (IRS) on certain
tax issues as a result of the IRS audits of certain UtiliCorp Federal income
tax returns (hereinafter referred to as "agreed-upon tax issues"). The Company
will be liable to UtiliCorp for approximately $3,100, under the provisions of
the tax sharing agreement (see Note 1), once UtiliCorp assesses the Company for
the agreed-upon tax issues. The payment of the income taxes associated with the
agreed-upon tax issues will have no effect on net income, as it will be an
adjustment to the deferred tax liability, upon assessment by UtiliCorp.

5.     MAJOR CUSTOMERS:

      The Company and its subsidiaries had gross sales as a percentage of total
revenue to non-affiliated major customers as follows:

5.    MAJOR CUSTOMERS: (CONTINUED)

      The Company's natural gas pipeline operations have a concentration of
customers in the natural gas transmission and distribution industries while its
NGLs operations have a concentration of customers in the refining and
petrochemical industries. These concentrations of customers may impact the
Company's overall exposure to credit risk, either positively or negatively, in
that the customers may be similarly affected by changes in economic or other
conditions. However, management believes that the Company's portfolio of
accounts receivable is sufficiently diversified to minimize any potential
credit risk. Historically, the Company has not incurred significant problems in
collecting its accounts receivable and, as such, no allowance for doubtful
accounts has been provided in the accompanying consolidated financial
statements. The Company's accounts receivable are generally not collateralized.

6.  RETIREMENT AND BENEFIT PLANS:

      UtiliCorp and its subsidiaries have a defined contribution plan for
virtually all employees. Pursuant to the plan, employees can defer a portion of
their compensation and contribute it to a deferred account. The Company's
matching contribution to the plan was $639, $519 and $453 in 1996, 1995 and
1994, respectively.

      The Company has a stock contribution plan under which eligible employees
receive a contribution of 3% of their base income in UtiliCorp's common stock.
The Company's expense associated with this plan was $345, $270 and $260 for
1996, 1995 and 1994, respectively.

      The Company has a stock option plan under which eligible employees were
granted options to purchase shares of UtiliCorp's common stock. The plan
provides that the options will not be granted at a price below the market price
at the date of grant. No compensation expense was charged to the Company for
1996, 1995 and 1994. At December 31, 1996, 1995 and 1994, 26,050, 26,750 and
27,250 shares, respectively, were outstanding at an option price of $27.3125
per share. All of the options were granted prior to 1994 and are not subject to
the provisions of SFAS 123.

      The Company has a stock appreciation rights plan, as amended, for key
members of management. Under the plan, the Company can award a total of 700,000
stock appreciation rights (SAR), each SAR giving the holder, upon exercise, the
right to receive a cash payment for the difference between the fair market
value of the Company's common stock on the date of grant and the fair market
value on the exercise date. Each SAR has a term of ten years from the date of
grant in which the employee may exercise the SAR. At the end of each reporting
period within the exercise period, the Company records an adjustment to
deferred compensation expense based upon the excess, if any, of the fair market
value of the Company's common stock and the option price of the related SAR. At
December 31, 1996, there were 254,344 SARs outstanding at an average price of
$12.024 per SAR. The Company's expense associated with this plan was $873 and
$241 for 1996 and 1995, respectively, while no compensation expense was
incurred in 1994.

      The Company awarded 6,295, 23,765 and 5,470 shares of the Company's
common stock in 1996, 1995 and 1994, respectively, to certain employees of the
Company as restricted stock awards. The shares issued as restricted stock
awards are held by the Company until certain restrictions lapse, generally on
the second or third award anniversary. The restricted stock, when awarded, is
amortized to compensation expense over a two to three year period. The
Company's expense associated with the restricted stock awards was $75 and $79
for 1996 and 1995, respectively, while no compensation expense was incurred in
1994.

      In 1996, the stockholders approved the 1996 Non-Employee Director Stock
Plan (Stock Plan). The Stock Plan authorizes the issuance of a maximum of
100,000 shares of the Company's common stock based on the fair market value of
the Company's common stock on the date of issuance. Each non-employee director
is to receive common stock of the Company equal to $2 on a quarterly basis for
services performed in the preceding quarter. In 1996, 298 shares of the
Company's common stock were issued and $4 of expense was recognized under the
Stock Plan.

LEASE OBLIGATIONS:

      The Company has various non-cancelable operating leases. Total rent
expense amounted to approximately $1,186, $994, and $558 for 1996, 1995 and

LETTERS OF CREDIT AND GUARANTIES:

      The Company has issued irrevocable standby letters of credit totaling
$15,102 at December 31, 1996. The standby letters of credit, which generally
have terms from one to three months, collateralize obligations to third parties
for the purchase of natural gas. The standby letters of credit are issued
pursuant to the line of credit discussed in Note 3.

      The Company issued financial guarantees of approximately $18,988 at
December 31, 1996, related to business activities of a 50% owned subsidiary.
Management does not believe it is probable that the financial guarantees will
be exercised.

LITIGATION:

            In 1987, HECI Exploration, Inc. (HECI) instituted a suit in the
      155th Judicial District Court, Fayette County, Texas, against the Company
      alleging various breaches of a take-or-pay contract and seeking
      approximately $3,000 in damages. The Company's motion for summary
      judgment was granted by the lower court. A Texas appellate court,
      however, has remanded the case for trial.

            In the purchase and sale agreement executed in connection with the
      1987 acquisition of Clajon Gas Company by a predecessor of the Company,
      Clayton Williams, Jr., individually, and certain selling entities agreed
      to jointly and severally indemnify the purchaser from liabilities related
      to the conduct of the acquired business or arising out of any assigned
      contracts prior to the closing date of the acquisition, subject to
      certain limitations. Thus, certain claims and litigation, including the
      HECI litigation described above, involving the acquired business and
      contracts assigned to the Company are subject to these indemnification
      provisions. The indemnity provision limits Mr. Williams' personal
      liability to $3,000 in the aggregate.

            In August 1995, Mr. Charles Menke instituted suit against the
      Company in the 155th Judicial District Court, Waller County, Texas,
      alleging the Company has constructed and was operating a pipeline on
      property owned by Mr. Menke. Mr. Menke alleges the Company is a
      trespasser on his property and seeks unspecified damages for such
      trespass including punitive damages. Mr. Menke additionally seeks an
      injunction requiring the Company to cease operation of its pipeline and
      to remove such line from his property. In October 1995, the Court denied
      Mr. Menke's request for a temporary injunction and set this matter for
      trial on January 15, 1996. By consent of all parties the January 15, 1996
      trial date was postponed and no new trial date has been set. The Company
      believes Mr. Menke's claims for injunctive relief are without merit, and
      believes it has meritorious defenses to the damage claims. The Company
      has filed a denial of all claims and is actively pursuing its defense of
      this litigation.

7.  COMMITMENTS AND CONTINGENCIES: (CONTINUED)

TAXES:

       The IRS has examined and proposed adjustments to UtiliCorp's
      consolidated Federal income tax returns for 1988 through 1991. The
      proposed adjustment affecting the Company is to lengthen the depreciable
      life of certain pipeline assets owned by the Company. Presently, no final
      resolution of the proposed adjustment has been reached with the IRS. The
      Company intends to vigorously contest the proposed adjustment and
      believes it is reasonably possible it will prevail. It is expected that
      additional assessments for the years 1992 though 1996 would be made on
      the same issue. Under the provisions of the tax sharing agreement with
      Aquila Energy and UtiliCorp (see Note 1) the Company would be liable to
      UtiliCorp for additional taxes of approximately $11,614 for the audit
      period and through 1996 plus potential interest of approximately $2,233
      on the contested proposed adjustment. The additional taxes would result
      in an adjustment to the deferred tax liability with no effect on net
      income, while any payment of interest would affect net income. The
      Company expects that the ultimate resolution of this matter will not have
      a material adverse effect on its financial position.

      The Company is also a party to additional claims and is involved in
various other litigation and administrative proceedings arising in the normal
course of business. The Company believes it is unlikely that the final outcome
of any of the claims, litigation or proceedings discussed above to which the
Company is a party would have a material adverse effect on the Company's
financial position or results of operations. However, due to the inherent
uncertainty of litigation, there can be no assurance that the resolution of any
particular claim or proceeding would not have an adverse effect on the
Company's results of operations for the fiscal period in which such resolution
occurred.

      The Company, in the normal course of business of its natural gas pipeline
operations, purchases and sells natural gas pursuant to long-term contracts.
Such contracts contain terms which are customary in the industry. The Company
believes that such terms are commercially reasonable and will not have a
material adverse effect on the Company's financial position or results of
operations.

8.  ACQUISITIONS:

      OASIS PIPE LINE COMPANY

      On July 1, 1996 and November 1, 1996, the Company completed the
acquisition of 15% and 25%, respectively, of the outstanding capital stock of
Oasis and related transportation rights from Dow Hydrocarbons and Resources
Inc. (DHRI) for a cash purchase price of $47,143 and $84,000, respectively. The
acquisition cost exceeded the Company's share of the underlying net assets of
Oasis by approximately $97,000. The transportation rights related to the 15%
and 25% capital stock acquisitions of Oasis currently amount to approximately
120 and 200 million cubic feet per day (MMcf/d), respectively, of firm
intrastate transportation between the Waha, Texas hub and the Katy, Texas hub,
plus the opportunity to utilize excess capacity on an interruptible basis. The
acquisitions were accounted for using the purchase method and are reflected in
the consolidated financial statements using the equity method of accounting.

      The Company, in connection with the November 1996 acquisition of Oasis,
entered into an option arrangement with El Paso Natural Gas Company (El Paso)
whereby the Company, under certain circumstances, may be required to sell to El
Paso 5% of all the capital stock of Oasis and the related transportation
rights. The sales price is $16.8 million, subject to certain adjustments.

      On January 31, 1997, the Company received notice from El Paso of its
intent to exercise the option arrangement. If consummated (expected close date
is April 1, 1997), the Company would own 35% of the capital stock of Oasis and
would have 280 MMcf/d of firm intrastate transportation capacity.

      (a)   The pro forma amounts do not include any adjustments to reflect the
            potential marketing activity that might have occurred if the
            Company had acquired Oasis as of January 1, 1995.

      The unaudited pro forma information is based upon available information 
and certain estimates and assumptions related to the accounting for the Oasis
acquisition that is subject to final determination. The unaudited pro forma
information is not necessarily indicative of the results that would have
occurred had such transaction actually taken place at the beginning of the
period specified nor does such information purport to project the results to
operations for any future date or period.

TRISTAR GAS COMPANY

      In January 1995, the Company acquired Tristar Gas Company (Tristar) for
$13,478 in cash. The Company assumed $21,786 of liabilities in connection with
the acquisition of $35,264 in assets, net of cash acquired, in this
transaction. This acquisition was accounted for using the purchase method of
accounting which resulted in excess of cost over fair value of net assets
acquired of $11,472 and an other intangible asset of $963 relating to a
favorable operating lease. The accompanying consolidated financial statements
of the Company include Tristar since the date of acquisition.

9.  COMMODITY RISK MANAGEMENT:

      The Company utilizes commodity financial instruments, primarily futures,
options and forward contracts (hedges or hedging), to reduce the risk of
commodity price fluctuations for its revenue share of natural gas and NGLs
throughput/production and its natural gas marketing operations. In its natural
gas marketing operations the Company hedges its physical delivery positions to
minimize the risk of gross margin variances between the time the physical
transactions occur and the contracts resulting in price risk are executed.
Accordingly, price changes in hedging positions are offset by price changes in
the physical transactions.

      Hedging and related activities may expose the Company to the risk of
financial loss in certain circumstances, including instances when (i)
throughput varies from expectations, (ii) the Company's contractual parties
fail to purchase or deliver the physical contracted quantities of natural gas
or NGLs, or (iii) the Company's hedging counterparties fail to perform. To the
extent the Company engages in hedging activities, it may be prevented from
realizing the benefits of favorable price changes in the physical market.

management function for its subsidiaries.

10.   FINANCIAL INSTRUMENTS:

      CASH AND CASH EQUIVALENTS, ACCOUNTS RECEIVABLE, OTHER CURRENT ASSETS, 
ACCOUNTS PAYABLE AND OTHER CURRENT LIABILITIES

      The Company's carrying amounts for cash and cash equivalents, accounts
receivable, other current assets, accounts payable and other current
liabilities approximate fair value.

      DEBT

      The carrying value of the debt approximates the fair value of the debt.
This determination is based on management's estimate of the fair value at which
such instruments could be sold or obtained in an unrelated third party
transaction.

      LETTERS OF CREDIT

      The fair value of the outstanding standby letters of credit of $15,102,
at December 31, 1996 is estimated to be the same as the contract value based on
the nature of the fee arrangements with the bank.

11.  INVESTMENT IN AFFILIATED COMPANY:

     The Company holds an investment in Oasis which is accounted for by the 
equity method of accounting. Dividends received from Oasis were $585 during
1996. The Company's net cost basis in Oasis is greater than the Company's share
of the underlying net assets of Oasis by $96,340 at December 31, 1996. The cost
over the underlying net assets is being amortized over approximately 35 years
based on the underlying assets depreciable lives. The amortization is included
in the equity in net income from Oasis.

     Summarized financial information of Oasis as of and for the year ended 
December 31, 1996 is as follows:
