                            OWNERSHIP OF OUR COMPANY

     We are the issuer of the common stock offered by this prospectus and the
parent and owner of Duke Energy Field Services, LLC. On March 31, 2000, the
North American midstream natural gas gathering, processing, marketing and
natural gas liquids businesses of Duke Energy Corporation ("Duke Energy") and
Phillips Petroleum Company ("Phillips") were combined into Duke Energy Field
Services, LLC.


     The following diagram is a summary of the ownership structure of our
company after giving effect to the offering of our common stock. After the
offering, Duke Energy and Phillips will together hold approximately 81.24%
(79.02% if the underwriters fully exercise their over-allotment option) of the
outstanding common stock in our company. Approximately 110,500 shares are
expected to be issued to employees under restricted stock awards issued
concurrently with the offering.


                              [DUKE ENERGY GRAPH]


     The exact allocation of shares between Duke Energy and Phillips will be
determined based on the average of the closing prices of our common stock on the
New York Stock Exchange Composite Tape on its first five trading days. Assuming
that the five-day average equals the assumed initial public offering price of
$21.00 per share, after the offering Duke Energy will indirectly own
approximately 58.65% (57.05% if the underwriters fully exercise their
over-allotment option) and Phillips will indirectly own approximately 22.59%
(21.97% if the underwriters fully exercise their over-allotment option) of our
outstanding common stock. Although the exact allocation between Duke Energy and
Phillips may vary, upon completion of the offering, Duke Energy will, in any
event, control our company through its share ownership and representation on our
Board of Directors. For a description of the combination of the North American
midstream natural gas businesses of Duke Energy and Phillips, see "Management's
Discussion and Analysis of Financial Condition and Results of Operations -- The
Combination." For a description of the relationships among Duke Energy, Phillips
and our company, see "Relationship with Duke Energy and Phillips."

     Duke Energy Field Services Corporation is a new company that holds the
combined North American midstream natural gas gathering, processing, marketing
and natural gas liquids businesses of Duke Energy Corporation and Phillips
Petroleum Company. The transaction in which those businesses were combined is
referred to in this prospectus as the "Combination." Our certificate of
incorporation limits the scope of our business to the midstream natural gas
industry in the United States and Canada, the marketing of natural gas liquids
in Mexico and the transportation, marketing and storage of other petroleum
products, unless otherwise approved by our Board of Directors and Duke Energy
(so long as it owns a majority of our outstanding common stock).



     Unless the context otherwise requires, descriptions of assets, operations
and results in this prospectus give effect to the Combination and related
transactions, the transfer to us of additional midstream natural gas assets
acquired by Duke Energy or Phillips prior to the Combination and the transfer to
us of the general partner of TEPPCO Partners, L.P., all of which are described
in more detail under "Management's Discussion and Analysis of Financial
Condition and Results of Operations -- The Combination." In this prospectus, the
terms "we," "us" and "our" refer to Duke Energy Field Services Corporation and
our subsidiaries, including our principal subsidiary, Duke Energy Field
Services, LLC (which we refer to as "Field Services LLC") giving effect to the
Combination and the other transactions described above.


                                  OUR COMPANY

     The midstream natural gas industry is the link between the exploration and
production of raw natural gas and the delivery of its components to end-use
markets. We operate in the two principal segments of the midstream natural gas
industry:

     - natural gas gathering, processing, transportation, marketing and storage;
       and


     - natural gas liquids ("NGLs") fractionation, transportation, marketing and
       trading.


     We are the largest gatherer of raw natural gas, based on wellhead volume,
and the largest producer of NGLs in North America. We are also one of the
largest marketers of NGLs in North America. In 1999:

     - we gathered and/or transported an average of approximately 7.3 billion
       cubic feet per day of raw natural gas;

     - we produced an average of approximately 400,000 barrels per day of NGLs;
       and

     - we marketed and traded an average of approximately 486,000 barrels per
       day of NGLs.

     During 1999, our natural gas gathering, processing, transportation,
marketing and storage segment produced $981.5 million of gross margin and $583.1
million of earnings before interest, taxes and depreciation and amortization
("EBITDA"), excluding general and administrative expenses, and our NGL
fractionation, transportation, marketing and trading segment produced $38.3
million of gross margin and $38.1 million of EBITDA, excluding general and
administrative expenses.

     We gather raw natural gas through gathering systems located in seven major
natural gas producing regions: Permian Basin, Mid-Continent, East Texas-Austin
Chalk-North Louisiana, Onshore Gulf of Mexico, Rocky Mountains, Offshore Gulf of
Mexico and Western Canada. Our gathering systems consist of approximately 57,000
miles of gathering pipe, with approximately 38,000 connections to active
producing wells.

                                        4
<PAGE>   6

     Our natural gas processing operations involve the separation of raw natural
gas gathered both by our gathering systems and by third-party systems into NGLs
and residue gas. We process the raw natural gas at our 70 owned and operated
plants and at 13 third-party operated facilities in which we hold an equity
interest.

     The NGLs separated from the raw natural gas by our processing operations
are either sold and transported as "NGL raw mix" or further separated through a
process known as fractionation into their individual components (ethane,
propane, butanes and natural gasoline) and then sold as components. We
fractionate NGL raw mix at our 12 owned and operated processing facilities and
at two third-party operated fractionators located on the Gulf Coast in which we
hold an equity interest.

     We sell NGLs to a variety of customers ranging from large, multi-national
petrochemical and refining companies to small regional retail propane
distributors. Substantially all of our NGL sales are made at market-based
prices, including approximately 40% of our NGL production that is committed to
Phillips under an existing 15-year contract. We market approximately 370,000
barrels per day of our NGLs processed at our owned and operated facilities and
approximately 40,000 barrels per day of NGLs processed at third-party operated
facilities and trade approximately 75,000 barrels per day of NGLs at market
centers.

     The residue gas that results from our processing is sold at market-based
prices to marketers or end-users, including large industrial customers and
natural gas and electric utilities serving individual consumers. We market
residue gas through our wholly owned gas marketing company. We also store
residue gas at our 8.5 billion cubic foot natural gas storage facility.

     On March 31, 2000, we obtained by transfer from Duke Energy the general
partner of TEPPCO Partners, L.P., a publicly traded limited partnership which
owns and operates a network of pipelines for refined products and crude oil. The
general partner is responsible for the management and operations of TEPPCO. We
believe that our ownership of the general partner of TEPPCO improves our
business position in the transportation sector of the midstream natural gas
industry and provides additional flexibility in pursuing our disciplined
acquisition strategy by providing an alternative acquisition vehicle. It also
provides us with an opportunity to sell appropriate assets currently held by our
company to TEPPCO. Through our ownership of the general partner of TEPPCO we
have the right to receive from TEPPCO incentive cash distributions in addition
to a 2% share of distributions based on our general partner interest. At
TEPPCO's 1999 per unit distribution level, the general partner:

     - receives approximately 14% of the cash distributed by TEPPCO to its
       partners, which consists of 12% from the incentive cash distribution and
       2% from the general partner interest; and

     - under the incentive cash distribution provisions, receives 50% of any
       increase in TEPPCO's per unit cash distributions.

     TEPPCO has agreed to acquire Atlantic Richfield Company's 50% ownership
interest in Seaway Pipeline Company for $355 million. Seaway Pipeline Company
owns a 500-mile crude oil pipeline that extends from a marine terminal at
Freeport, Texas to Cushing, Oklahoma having a capacity of 350,000 barrels per
day, a 550-mile refined products pipeline that extends from Pasadena, Texas to
Cushing having a capacity of 85,000 barrels per day and a crude oil terminal
facility in the Houston area. TEPPCO will assume ARCO's role as operator of
Seaway. The transaction is contingent upon satisfaction of regulatory
requirements.

                             OUR BUSINESS STRATEGY

     We are the largest gatherer of raw natural gas and the largest producer and
one of the largest marketers of NGLs in North America. We have significant
midstream natural gas operations in five of the largest natural gas producing
regions in North America. Our certificate of incorporation limits the scope of
our business to the midstream natural gas industry in the United States and
Canada, the marketing of NGLs in Mexico and the transportation, marketing and
storage of other petroleum products, unless otherwise approved by our Board of
Directors and Duke Energy (so long as it owns a majority of our outstanding
common stock). To

                                        5
<PAGE>   7

take advantage of the anticipated growth in natural gas demand in North America,
we are pursuing the following strategies:

     - Capitalize on the size and focus of our existing operations. We intend to
       use the size, scope and concentration of our assets in our regions of
       operation to take advantage of growth opportunities and to acquire
       additional supplies of raw natural gas. Our significant market presence
       and asset base generally provide us a competitive advantage in capturing
       new supplies of raw natural gas because of our resulting lower costs of
       connection to new wells and of processing additional raw natural gas. In
       addition, we believe our size and geographic diversity allow us to
       benefit from the growth of natural gas production in multiple regions
       while mitigating the adverse effects from a downturn in any one region.

     - Increase our presence in each aspect of the midstream business. We are
       active in each significant aspect of the midstream natural gas value
       chain, including raw natural gas gathering, processing and
       transportation, NGL fractionation and NGL and residue gas transportation
       and marketing. Each link in the value chain provides us with an
       opportunity to earn incremental income from the raw natural gas that we
       gather and from the NGLs and residue gas that we produce. We intend to
       grow our significant NGL market presence by investing in additional NGL
       infrastructure, including pipelines, fractionators and terminals.

     - Increase our presence in high growth production areas. According to the
       Energy Information Administration's report "Annual Energy Outlook 2000"
       (the "EIA Report") production from areas such as Western Canada, Onshore
       Gulf of Mexico, Rocky Mountains and Offshore Gulf of Mexico is expected
       to increase significantly to meet anticipated increases in demand for
       natural gas in North America. We intend to use our strategic asset base
       in these growth areas and our leading position in the midstream natural
       gas industry as a platform for future growth in these areas. We plan to
       increase our operations in these areas by following a disciplined
       acquisition strategy, expanding existing infrastructure and constructing
       new gathering lines and processing facilities.

     - Capitalize on proven acquisition skills in a consolidating industry. In
       addition to pursuing internal growth by attracting new raw natural gas
       supplies, we intend to use our substantial acquisition and integration
       skills to continue to participate selectively in the consolidation of the
       midstream natural gas industry. We have pursued a disciplined acquisition
       strategy focused on acquiring complementary assets during periods of
       relatively low commodity prices and integrating the acquired assets into
       our operations. Since 1996, we have completed over 20 acquisitions,
       increasing our raw natural gas processing capacity by over 275%. These
       acquisitions demonstrate our ability to successfully identify, acquire
       and integrate attractive midstream natural gas operations.

     - Further streamline our low-cost structure. Our economies of scale,
       operating efficiency and resulting low cost structure enhance our ability
       to attract new raw natural gas supplies and generate current income. The
       low-cost provider in any region can more readily attract new raw natural
       gas volumes by offering more competitive terms to producers. We believe
       the Combination provides us with a complementary base of assets from
       which to further extract operating efficiencies and cost reductions,
       while continuing to provide superior customer service.

              PRESENTATION OF FINANCIAL INFORMATION AND OTHER DATA


     Duke Energy Field Services Corporation is a new company that holds the
combined North American midstream natural gas businesses of Duke Energy and
Phillips.


     Because our operations have only recently been combined and these
operations have grown significantly through acquisitions, our historical and pro
forma financial information and operating data may not provide an accurate
indication of:

     - what our actual results would have been if the transactions presented on
       a pro forma basis had actually been completed as of the dates presented;
       or

     - what our future results of operations are likely to be.

HISTORICAL FINANCIAL INFORMATION AND OTHER DATA

     From a financial reporting perspective, we are the successor to Duke
Energy's North American midstream natural gas business. The subsidiaries of Duke
Energy that conducted this business were contributed to Duke Energy Field
Services Corporation in December 1999 in contemplation of the Combination. Duke
Energy Field Services Corporation and these former subsidiaries of Duke Energy
collectively are referred to in this prospectus as the "Predecessor Company."
The historical financial statements and related financial and other data
included in this prospectus reflect the business of the Predecessor Company.
This historical financial information and other data should be viewed in light
of the following:

     - the Combination is reflected as a March 31, 2000 acquisition of the
       midstream natural gas business contributed to our company by Phillips in
       the Combination;

     - the Predecessor Company's acquisition of Union Pacific Fuels is reflected
       as a March 31, 1999 acquisition by the Predecessor Company; and

     - the historical financial statements of the Predecessor Company do not
       include the results of the general partner of TEPPCO.

     For your additional information, we have also included the audited
financial statements of:


     - the midstream natural gas business of Phillips that was transferred to us
       in the Combination; and


     - Union Pacific Fuels.

PRO FORMA FINANCIAL AND OTHER INFORMATION

     In addition to the historical financial information and other data, this
prospectus includes:

     - unaudited pro forma financial statements of our company for 1999 and the
       three months ended March 31, 2000, each reflecting:

                   SUMMARY HISTORICAL AND PRO FORMA COMBINED
                            FINANCIAL AND OTHER DATA

     The following table sets forth summary historical financial and other data
for the Predecessor Company. The historical income statement data and cash flow
data for each of the three years ended December 31, 1999 and the historical
balance sheet data as of December 31 in each of those three years have been
derived from the Predecessor Company's audited historical financial statements.
The historical financial data for the three months ended March 31, 2000 has been
derived from unaudited financial statements. The historical data set forth below
relates only to the Predecessor Company and does not reflect the results of
operations or financial condition of the Phillips businesses transferred to us
in the Combination. In addition, the following table sets forth selected pro
forma financial and operating data, which reflect the historical results of
operations of the Predecessor Company, adjusted for:

     - the acquisition of the midstream natural gas business of Phillips in the
       Combination;

     - the acquisition of Union Pacific Fuels;

     - incurrence of indebtedness to fund the cash distributions to Duke Energy
       and Phillips in connection with the Combination as described in
       "Management's Discussion and Analysis of Financial Condition and Results
       of Operations;"


     - the offering of our common stock and the expected application of the
       estimated proceeds;


     - the transfer to our company of additional midstream natural gas assets
       acquired by Duke Energy or Phillips prior to consummation of the
       Combination; and

     - the transfer to our company of the general partner of TEPPCO;

as if all had occurred as of January 1, 1999 for income statement purposes and
March 31, 2000 for balance sheet purposes. The data should be read in
conjunction with the financial statements and related notes and other financial
information appearing elsewhere in this prospectus. The pro forma data set forth
below are not necessarily indicative of results that may occur in the future.

                                  RISK FACTORS

     Investing in our common stock will provide you with an equity ownership
interest in our company. As a stockholder, you will be subject to risks inherent
in our business. The performance of your shares will reflect the performance of
our business relative to, among other things, competition, market conditions and
general economic and industry conditions. The value of your investment may
increase or decrease and you could suffer a loss. You should carefully consider
the risks described below as well as the other information contained in this
prospectus. Additional risks currently not known to us or that we currently deem
immaterial may also impair our business operations.

RISKS RELATED TO OUR BUSINESS AND OPERATIONS

     OUR BUSINESS IS DEPENDENT UPON PRICES AND MARKET DEMAND FOR OIL, NATURAL
GAS AND NGLS, WHICH ARE BEYOND OUR CONTROL AND HAVE BEEN EXTREMELY VOLATILE.

     We are subject to significant risks due to fluctuations in commodity
prices, primarily with respect to the prices of NGLs that we own as a result of
our processing activities. For example, based upon our portfolio of supply
contracts in 1999, and excluding the effects of our commodities risk management
program, a decrease of $.01 per gallon in the price of NGLs and of $.10 per
million Btus in the average price of natural gas throughout 1999 would have
resulted in changes in pre-tax net income of approximately ($24) million and $1
million, respectively. In the past, the prices of residue gas and NGLs have been
extremely volatile and we expect this volatility to continue.

     The markets and prices for residue gas and NGLs depend upon factors beyond
our control. These factors include demand for oil, natural gas and NGLs, which
fluctuate with changes in market and economic conditions and other factors,
including:

     - the impact of weather on the demand for oil and natural gas;

     - the level of domestic oil and natural gas production;

     - the availability of imported oil and natural gas;

     - the availability of local, intrastate and interstate transportation
       systems;

     - the availability and marketing of competitive fuels;

     - the impact of energy conservation efforts; and

     - the extent of governmental regulation and taxation.

     WE MUST CONTINUALLY COMPETE FOR RAW NATURAL GAS SUPPLY, AND OUR SUCCESS
DEPENDS UPON THE AVAILABLE SUPPLY OF RAW NATURAL GAS.

     In order to maintain or increase throughput levels in our raw natural gas
gathering systems and asset utilization rates at our processing plants, we must
continually contract for new raw natural gas supplies to offset natural declines
in connected supplies of raw natural gas. Our future growth will depend, in
part, upon whether we can contract for additional supplies at a greater rate
than the rate of natural decline in our currently connected supplies. The
primary factors affecting our ability to connect new wells to our gathering
facilities include our success in contracting for existing producing raw natural
gas supplies that are not committed to other systems and the level of drilling
activity near our gathering systems. Drilling activity generally increases (or
decreases) as oil and natural gas prices increase (or decrease). Our industry is
highly competitive, and we cannot assure you that we will be able to obtain
additional contracts for raw natural gas supplies.

     Our results are materially affected by the volume of raw natural gas
processed at our facilities and asset utilization rates. Fluctuations in energy
prices can greatly affect production rates and investments by third parties in
the development of new oil and natural gas reserves. A material decrease in
natural gas production for a prolonged period in the areas where our gathering
facilities are located, as a result of depressed

                                       12
<PAGE>   14

commodity prices or otherwise, likely would have a material adverse effect on
our results of operations and financial position.

     BECAUSE WE ARE A NEWLY COMBINED COMPANY WITH NO COMBINED OPERATING HISTORY,
NEITHER OUR HISTORICAL NOR OUR PRO FORMA FINANCIAL AND OPERATING DATA MAY BE
REPRESENTATIVE OF OUR FUTURE RESULTS.

     We are a newly combined company with no combined operating history. Our
lack of a combined operating history may make it difficult to forecast our
future operating results. Our historical financial statements included in this
prospectus reflect the historical results of operations, financial position and
cash flows of the midstream natural gas businesses of Duke Energy prior to the
Combination. The unaudited pro forma financial information included in this
prospectus are based on the two separate midstream businesses of Duke Energy and
Phillips prior to the Combination, each of which were managed separately prior
to the Combination. As a result, the historical and pro forma information may
not give you an accurate indication of what our actual results would have been
if the Combination had been completed at the beginning of the periods presented
or of what our future results of operations are likely to be. In addition, our
future results will depend on our ability to integrate our operations,
efficiently manage our combined facilities and execute our business strategy.

     A SIGNIFICANT COMPONENT OF OUR GROWTH STRATEGY IS ACQUISITIONS, AND WE MAY
NOT BE ABLE TO COMPLETE FUTURE ACQUISITIONS SUCCESSFULLY.

     Our business strategy has emphasized growth through strategic acquisitions,
but we cannot assure you that we will be able to continue to identify attractive
or willing acquisition candidates or that we will be able to acquire these
candidates on economically acceptable terms. Competition for acquisition
opportunities in our industry exists and may increase. Any increase in the level
of competition for acquisitions may increase the cost of, or cause us to refrain
from, completing acquisitions.

     Our strategy of completing acquisitions is dependent upon, among other
things, our ability to obtain debt and equity financing and regulatory
approvals. Our ability to pursue our growth strategy may be hindered if we are
not able to obtain financing or regulatory approvals, including those under
federal and state antitrust laws. Our ability to grow through acquisitions and
manage such growth will require us to continue to invest in operational,
financial and management information systems and to attract, retain, motivate
and effectively manage our employees. The inability to manage the integration of
acquisitions effectively could have a material adverse effect on our financial
condition, results of operations and business. Pursuit of our acquisition
strategy may cause our financial position and results of operations to fluctuate
significantly from period to period.

     GROWING OUR BUSINESS BY CONSTRUCTING NEW PIPELINES AND PROCESSING
FACILITIES SUBJECTS US TO CONSTRUCTION RISKS AND RISKS THAT RAW NATURAL GAS
SUPPLIES WILL NOT BE AVAILABLE UPON COMPLETION OF THE FACILITIES.

     One of the ways we intend to grow our business is through the construction
of additions to our existing gathering systems and construction of new
processing facilities. The construction of gathering and processing facilities
requires the expenditure of significant amounts of capital, which may exceed our
expectations. Generally, we may have only limited raw natural gas supplies
committed to these facilities prior to their construction. Moreover, we may
construct facilities to capture anticipated future growth in production in a
region in which anticipated production growth does not materialize. As a result,
there is the risk that new facilities may not be able to attract enough raw
natural gas to achieve our expected investment return, which could adversely
affect our results of operations and financial condition.

     WE OPERATE IN HIGHLY COMPETITIVE MARKETS IN COMPETITION WITH A NUMBER OF
DIFFERENT COMPANIES.

     We face strong competition in our geographic areas of operations. Our
competitors include major integrated oil companies, interstate and intrastate
pipelines and raw natural gas gatherers and processors. Some of our competitors
offer more services or have greater financial resources and access to larger raw
natural gas supplies than we do. We compete with integrated companies that have
greater access to raw natural gas supply and are less susceptible to
fluctuations in price or volume, and some of our competitors that

                                       13
<PAGE>   15

have greater financial resources may have an advantage in competing for
acquisitions or other new business opportunities.

     FEDERAL, STATE OR LOCAL REGULATORY MEASURES COULD ADVERSELY AFFECT OUR
BUSINESS.

     While the Federal Energy Regulatory Commission, or FERC, does not directly
regulate the major portions of our operations, federal regulation, directly or
indirectly, influences certain aspects of our business and the market for our
products. As a raw natural gas gatherer and not an operator of interstate
transmission pipelines, we generally are exempt from FERC regulation under the
Natural Gas Act of 1938, but FERC regulation still significantly affects our
business. In recent years, FERC has pursued pro-competition policies in its
regulation of interstate natural gas pipelines. However, we cannot assure you
that FERC will continue this approach as it considers proposals by pipelines to
allow negotiated rates not limited by rate ceilings, pipeline rate case
proposals and revisions to rules and policies that may affect rights of access
to natural gas transportation capacity.

     While state public utility commissions do not regulate our business, state
and local regulations do affect our business. We are subject to ratable take and
common purchaser statutes in the states where we operate. Ratable take statutes
generally require gatherers to take, without undue discrimination, natural gas
production that may be tendered to the gatherer for handling. Similarly, common
purchaser statutes generally require gatherers to purchase without undue
discrimination as to source of supply or producer. These statutes are designed
to prohibit discrimination in favor of one producer over another producer or one
source of supply over another source of supply. These statutes also have the
effect of restricting our right as an owner of gathering facilities to decide
with whom we contract to purchase or transport natural gas. Federal law leaves
any economic regulation of raw natural gas gathering to the states, and some of
the states in which we operate have adopted complaint-based or other limited
economic regulation of raw natural gas gathering activities. States in which we
operate that have adopted some form of complaint-based regulation, like
Oklahoma, Kansas and Texas, generally allow natural gas producers and shippers
to file complaints with state regulators in an effort to resolve grievances
relating to natural gas gathering access and rate discrimination. The states in
which we conduct operations administer federal pipeline safety standards under
the Pipeline Safety Act of 1968, and the "rural gathering exemption" under that
statute that our gathering facilities currently enjoy may be restricted in the
future. The "rural gathering exemption" under the Natural Gas Pipeline Safety
Act of 1968 presently exempts substantial portions of our gathering facilities
from jurisdiction under that statute, including those portions located outside
of cities, towns, or any area designated as residential or commercial, such as a
subdivision or shopping center. See "Business -- Regulation."

     OUR BUSINESS INVOLVES HAZARDOUS SUBSTANCES AND MAY BE ADVERSELY AFFECTED BY
ENVIRONMENTAL REGULATION.

     Many of the operations and activities of our gathering systems, plants and
other facilities are subject to significant federal, state and local
environmental laws and regulations. These include, for example, laws and
regulations that impose obligations related to air emissions and discharge of
wastes from our facilities and the clean up of hazardous substances that may
have been released at properties currently or previously owned or operated by us
or locations to which we have sent wastes for disposal. Various governmental
authorities have the power to enforce compliance with these regulations and the
permits issued under them, and violators are subject to administrative, civil
and criminal penalties, including civil fines, injunctions or both. Liability
may be incurred without regard to fault for the remediation of contaminated
areas. Private parties, including the owners of properties through which our
gathering systems pass, may also have the right to pursue legal actions to
enforce compliance as well as to seek damages for non-compliance with
environmental laws and regulations or for personal injury or property damage.

     There is inherent risk of the incurrence of environmental costs and
liabilities in our business due to our handling of natural gas and other
petroleum products, air emissions related to our operations, historical industry
operations, waste disposal practices and the prior use of natural gas flow
meters containing mercury. In addition, the possibility exists that stricter
laws, regulations or enforcement policies could significantly increase our
compliance costs and the cost of any remediation that may become necessary. We
cannot assure you that we will not incur material environmental costs and
liabilities. Furthermore, we cannot assure you that our insurance will provide
sufficient coverage in the event an environmental claim is made against us.
                                       14
<PAGE>   16

     Our business may be adversely affected by increased costs due to stricter
pollution control requirements or liabilities resulting from non-compliance with
required operating or other regulatory permits. New environmental regulations
might adversely affect our products and activities, including processing,
storage and transportation, as well as waste management and air emissions.
Federal and state agencies also could impose additional safety requirements, any
of which could affect our profitability.

     OUR BUSINESS INVOLVES MANY HAZARDS AND OPERATIONAL RISKS, SOME OF WHICH MAY
NOT BE COVERED BY INSURANCE.


     Our operations are subject to the many hazards inherent in the gathering,
compressing, treating and processing of raw natural gas and NGLs and storage of
residue gas, including ruptures, leaks and fires. These risks could result in
substantial losses due to personal injury and/or 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 our related operations. We
are not fully insured against all risks incident to our business. If a
significant accident or event occurs that is not fully insured, it could
adversely affect our operations and financial condition.


     OUR USE OF DERIVATIVE FINANCIAL INSTRUMENTS HAS IN THE PAST AND COULD IN
THE FUTURE RESULT IN FINANCIAL LOSSES OR REDUCE OUR INCOME.

     We use futures and option contracts traded on the New York Mercantile
Exchange and over-the-counter options and price and basis swaps with other
natural gas merchants and financial institutions. Use of these instruments is
intended to reduce our exposure to short-term volatility in commodity prices. We
could, however, incur financial losses or fail to recognize the full value of a
market opportunity as a result of volatility in the market values of the
underlying commodities or if one of our counterparties fails to perform under a
contract.

     Duke Energy has conducted our commodity risk management activities since
late 1998. Prior to that time, we did not engage in significant commodity risk
management activities. In the past, Duke Energy used crude oil price swaps to
hedge a portion of our exposure to decreasing NGL prices and generally increased
the level of hedging as prices increased. This strategy resulted in a $34.0
million hedging loss in 1999 and a $46.7 million hedging loss in the first
quarter of 2000 due to crude oil prices rising above the level at which they
were hedged. Effective with the Combination, we began conducting our commodity
risk management activities independent of Duke Energy. We anticipate that we
will generally hedge a lower percentage of our cash flows compared to the
historical hedging levels undertaken by Duke Energy on our behalf.


     For additional information about our risk management activities, including
our use of derivative financial instruments, see "Management's Discussion and
Analysis of Financial Condition and Results of Operations -- Quantitative and
Qualitative Disclosure about Market Risks."


     OUR SUCCESS DEPENDS ON KEY MEMBERS OF OUR MANAGEMENT, THE LOSS OF WHOM
COULD DISRUPT OUR BUSINESS OPERATIONS.

     We depend on the continued employment and performance of Jim W. Mogg,
Michael J. Panatier, Mark A. Borer, Michael J. Bradley, David D. Frederick,
Robert F. Martinovich, William W. Slaughter and Martha B. Wyrsch. We have
entered into an employment agreement with Mr. Panatier and a consulting
agreement with Mr. Slaughter. See "Management -- Employment and Consulting
Agreements." If our key managers resign or become unable to continue in their
present roles and are not adequately replaced, our business operations could be
materially adversely affected. We do not maintain any "key man" life insurance
for any officers. See "Management."

RISKS RELATED TO OUR RELATIONSHIP WITH DUKE ENERGY AND PHILLIPS

     DUKE ENERGY AND PHILLIPS WILL CONTROL THE OUTCOME OF STOCKHOLDER VOTING AND
MAY EXERCISE THEIR VOTING POWER IN A MANNER ADVERSE TO YOU.


     After the offering, Duke Energy and Phillips will together hold
approximately 81.24% of the outstanding common stock of our company. The exact
allocation of these shares between Duke Energy and Phillips will be

                                       15
<PAGE>   17


determined based on the average of the closing prices of our common stock on the
New York Stock Exchange Composite Tape on its first five trading days. Assuming
that the five-day average is the same as the assumed initial public offering
price, after the offering Duke Energy will indirectly own approximately 58.65%
(57.05% if the underwriters fully exercise their over-allotment option) and
Phillips will indirectly own approximately 22.59% (21.97% if the underwriters
fully exercise their over-allotment option) of our outstanding common stock.
Although the exact allocation between Duke Energy and Phillips may vary, upon
completion of the offering, Duke Energy will, in any event, control our company
through its share ownership and representation on our Board of Directors.


     Accordingly, Duke Energy and Phillips are in a position to control the
outcome of matters requiring a stockholder vote, including the election of
directors, adoption of an amendment to our certificate of incorporation or
bylaws or approving transactions involving a change of control. In addition, our
certificate of incorporation grants each of Duke Energy and Phillips the right
to purchase shares of common stock in our future public offerings in an amount
sufficient to maintain its percentage ownership in our company so long as each
owns at least 20% of our common stock.

     Duke Energy and Phillips have agreed to vote their shares of common stock
in a manner that ensures that seven designees of Duke Energy (two of whom are
required to be independent directors) and four designees of Phillips (one of
whom is required to be an independent director) are elected to our Board of
Directors. Our bylaws require the approval of at least eight of our 11 directors
for authorization of a variety of corporate actions, including significant
acquisitions, dispositions, capital expenditures and borrowings. As a result,
Duke Energy and Phillips have the ability to control our policies, management
and affairs, including decisions regarding the acquisition or disposition of
assets, business combinations, issuances of common stock and the declaration of
dividends. For example, Duke Energy and Phillips could prevent transactions that
would dilute their respective ownership interests in our company, including
prospective acquisitions that we would finance by issuing shares of our common
stock. The interests of Duke Energy and Phillips may differ from yours, and they
may vote their common stock in a manner that may adversely affect you.

     SEVERAL OF OUR DIRECTORS AND OFFICERS MAY HAVE CONFLICTS OF INTEREST
BECAUSE THEY ARE ALSO DIRECTORS OR OFFICERS OF DUKE ENERGY, PHILLIPS OR THE
GENERAL PARTNER OF TEPPCO.


     After completion of the offering, five of our directors also will be past
or current directors or officers of Duke Energy, four of our directors will be
past or current directors or officers of Phillips and four of our directors or
officers will be directors of the general partner of TEPPCO, a situation that
may create conflicts of interest. These directors and officers have dual
responsibilities. Directors and officers of Duke Energy and Phillips have
fiduciary duties to manage Duke Energy and Phillips, including their investments
in subsidiaries and affiliates such as us, in a manner beneficial to Duke Energy
and Phillips and their stockholders. Directors and officers of the general
partner of TEPPCO have fiduciary duties to manage the business of TEPPCO in a
manner beneficial to TEPPCO and its unitholders, including its public
unitholders. As directors and officers of our company, they also have fiduciary
duties to manage us in a manner beneficial to us and our stockholders. Their
duties as directors or officers of Duke Energy, Phillips or the general partner
of TEPPCO may conflict with their duties as directors or officers of our company
with respect to corporate opportunities, business dealings among Duke Energy,
Phillips, TEPPCO and us and other corporate matters. For example, Duke Energy,
Phillips, TEPPCO and our company are engaged in related lines of business, and
we may have similar acquisition strategies. As a result, conflicts may arise
because acquisition opportunities that may be beneficial to more than one
company may be presented to our officers or directors who are also officers or
directors of Duke Energy, Phillips or the general partner of TEPPCO. Other
conflicts of interest may arise in the future as a result of the extensive
relationships among our company, Duke Energy, Phillips and TEPPCO. The
resolution of these conflicts may not always be in our or our stockholders' best
interest.


     OUR BUSINESS OPPORTUNITIES COULD BE LIMITED BECAUSE DUKE ENERGY, PHILLIPS
AND THEIR RESPECTIVE AFFILIATES MAY COMPETE WITH US IN MIDSTREAM NATURAL GAS
ACTIVITIES, AND WE MAY ONLY ENGAGE IN THE LIMITED ACTIVITIES DESCRIBED IN THIS
PROSPECTUS.


     Our certificate of incorporation limits the scope of our business to the
midstream natural gas industry in the United States and Canada and the marketing
of NGLs in Mexico and the transportation, marketing and

                                       16
<PAGE>   18


storage of other petroleum products and does not permit us to pursue other
potentially profitable activities. Duke Energy and its affiliates are permitted
to engage in the midstream natural gas industry and related businesses, even if
it has a negative competitive effect on us. We cannot amend these provisions of
our certificate of incorporation without Duke Energy's prior consent (so long as
Duke Energy owns a majority of our outstanding common stock), which Duke Energy
may withhold at its sole discretion. Phillips also has retained midstream
natural gas assets in its exploration and production organization and is
permitted to engage in the midstream natural gas industry and related
businesses, even if it has a negative competitive effect on our company.


     DUKE ENERGY'S OWNERSHIP INTEREST AND PROVISIONS CONTAINED IN OUR
CERTIFICATE OF INCORPORATION COULD DISCOURAGE A TAKEOVER ATTEMPT, WHICH MAY
REDUCE OR ELIMINATE THE LIKELIHOOD OF A CHANGE OF CONTROL TRANSACTION AND,
THEREFORE, YOUR ABILITY TO SELL YOUR SHARES FOR A PREMIUM.

     In addition to Duke Energy's controlling position, provisions contained in
our certificate of incorporation, such as limitations on stockholder proposals
at meetings of stockholders and the inability of stockholders to call special
meetings, could make it more difficult for a third party to acquire control of
our Company, even if some of our stockholders considered such a change of
control to be beneficial. Our certificate of incorporation also authorizes our
Board of Directors to issue preferred stock without stockholder approval. If our
Board of Directors elects to issue preferred stock, it could make it even more
difficult for a third party to acquire us, which may reduce or eliminate your
ability to sell your shares of common stock at a premium. See "Description of
Capital Stock."

     OUR COSTS RELATED TO CORPORATE SERVICES COULD INCREASE AS OUR RELATIONSHIP
WITH DUKE ENERGY OR PHILLIPS CHANGES IN THE FUTURE.

     We have entered into agreements with Duke Energy and Phillips under which
Duke Energy and Phillips provide corporate support services to us. Our
agreements with Duke Energy and Phillips expire, unless extended, on December
31, 2000. Replacing such services, either internally or through third-party
providers, may cause disruptions in our operations or result in costs in excess
of our historical costs for similar services.

     PHILLIPS HAS NOT YET COMPLETELY TRANSFERRED TO US RECORD TITLE TO ALL OF
ITS MIDSTREAM ASSETS THAT WERE TRANSFERRED TO US IN THE COMBINATION. IN THE
EVENT OF A BANKRUPTCY OF PHILLIPS, WE MAY NOT BE ABLE TO OBTAIN RECORD TITLE TO
THESE ASSETS.

     Although Phillips has transferred to us the midstream natural gas assets it
contributed in the Combination, Phillips and its affiliates continue to hold
record title to some of the real property for our benefit. Although Phillips is
in the process of transferring record title to us, the process may not be
completed for some time. In the event of a Phillips bankruptcy before record
title has been conveyed to us, we may have difficulty or be unable to obtain
record title to these properties. The failure to complete this planned record
title transfer could have a material adverse effect on our business, operations
and financial results.

RISKS RELATED TO OWNERSHIP OF OUR COMMON STOCK

     YOU WILL EXPERIENCE IMMEDIATE AND SUBSTANTIAL DILUTION.


     The initial public offering price is substantially higher than the
pre-offering net tangible book value per share of our common stock. Purchasers
of our common stock in the offering will experience immediate and substantial
dilution. The dilution to new investors will be approximately $7.53 per share in
net tangible book value. See "Dilution."


     THERE HAS BEEN NO PRIOR PUBLIC MARKET FOR OUR COMMON STOCK, AND THE PRICE
OF OUR STOCK MAY BE SUBJECT TO FLUCTUATIONS.


     No market for our common stock existed prior to this offering, and although
our shares of common stock have been approved for listing, subject to official
notice of issuance, on the New York Stock Exchange, we cannot assure you that a
viable trading market for our common stock will develop or be sustained.


                                       17
<PAGE>   19

     The initial public offering price was determined by negotiations among us,
Duke Energy and the underwriters based on numerous factors. The market price of
our common stock after this offering may vary from the initial public offering
price, and you may not be able to resell your shares at or above the initial
public offering price. The market price of our common stock is likely to be
volatile and could be subject to fluctuations in response to factors such as the
following, most of which are beyond our control:

     - operating results that vary from the expectations of securities analysts
       and investors;

     - changes in expectations as to our future financial performance, including
       financial estimates by securities analysts and investors;

     - the operations, regulatory, market and other risks discussed in this
       section;

     - announcements by us or our competitors of significant contracts,
       acquisitions, strategic partnerships, joint ventures or capital
       commitments;

     - announcements by third parties of significant claims or proceedings
       against us; and

     - future sales of our common stock.

In addition, the stock market has from time to time experienced extreme price
and volume fluctuations. These broad market fluctuations may adversely affect
the market price of our common stock.

     FUTURE SALES OF OUR COMMON STOCK BY EXISTING STOCKHOLDERS COULD DEPRESS OUR
STOCK PRICE.


     Sales of a substantial number of shares of our common stock after the
offering could adversely affect the market price of our common stock by
introducing a significant increase in the supply of common stock to the market.
This increased supply could cause the market price of our common stock to
decline significantly.



     After the offering, we will have outstanding 140,752,211 shares of common
stock, and we will have reserved 4,000,000 shares of common stock for issuance
under our 2000 Long-Term Incentive Plan. All the shares of common stock sold in
the offering will be freely tradable without restriction or further registration
under the federal securities laws unless purchased by one of our "affiliates,"
as that term is defined in Rule 144 under the Securities Act of 1933. The
remaining shares of outstanding common stock, including shares held by Duke
Energy, Phillips and their affiliates, will be "restricted securities" under the
Securities Act and will be subject to restrictions on the timing, manner and
volume of sales of restricted shares.



     In connection with the offering, we and our officers and directors, as well
as Duke Energy and Phillips, have agreed not to sell any shares of common stock
for a period of 180 days after the date of this prospectus without the prior
written consent of Morgan Stanley & Co. Incorporated. The lock-up to which we
are a party does not apply to our securities issued under our existing benefit
plans, including our 2000 Long-Term Incentive Plan. The lock-up to which Duke
Energy, Phillips and our officers and directors are a party does not apply to
our securities acquired by them in open market transactions after completion of
the offering. Morgan Stanley & Co. Incorporated has sole discretion to waive any
of the provisions of any of these lock-up agreements. Upon expiration of the
lock-up period, the shares outstanding and owned by Duke Energy, Phillips and
their affiliates may be sold in the future without registration under the
Securities Act to the extent permitted by Rule 144 or any applicable exemption
under the Securities Act. Under a registration rights agreement between Duke
Energy, Phillips and our company, Duke Energy, Phillips and their affiliates
have the right to require us to register their shares of our common stock
following the lock-up period. The possibility that Duke Energy, Phillips or any
of their or our affiliates may dispose of shares of our common stock, or the
announcement or completion of any such transaction, could have an adverse effect
on the market price of our common stock. See "Shares Eligible for Future Sale."


             CAUTIONARY STATEMENT ABOUT FORWARD-LOOKING STATEMENTS

     This prospectus contains statements that do not directly or exclusively
relate to historical facts. Such statements are "forward-looking statements"
within the meaning of the Private Securities Litigation Reform Act of 1995. You
can typically identify forward-looking statements by the use of forward-looking
words, such
                                       18
<PAGE>   20

as "may," "could," "project," "believe," "anticipate," "expect," "estimate,"
"potential," "plan," "forecast" and other similar words.

     All statements other than statements of historical facts contained in this
prospectus, including statements regarding our future financial position,
business strategy, budgets, projected costs and plans and objectives of
management for future operations, are forward-looking statements.

     The forward-looking statements in this prospectus reflect our intentions,
plans, expectations, assumptions and beliefs about future events and are subject
to risks, uncertainties and other factors, many of which are outside our
control. Important factors that could cause actual results to differ materially
from the expectations expressed or implied in the forward-looking statements
include known and unknown risks. Known risks include, but are not limited to,
those listed in the "Risk Factors" section and elsewhere in this prospectus.

     In light of these risks, uncertainties and assumptions, the events
described in the forward-looking statements in this prospectus might not occur
or might occur to a different extent or at a different time than described in
this prospectus. We undertake no obligation to update or revise our
forward-looking statements, whether as a result of new information, future
events or otherwise.

                                USE OF PROCEEDS


     We expect the net proceeds to us from the offering to be approximately $521
million ($600 million if the underwriters fully exercise their over-allotment
option).



     We intend to use the net proceeds that we receive from the offering to
repay a portion of our outstanding commercial paper. The proceeds of the
commercial paper were used to make one-time cash distributions of approximately
$1.5 billion to Duke Energy and approximately $1.2 billion to Phillips and for
working capital requirements. At April 30, 2000, our outstanding commercial
paper had maturity dates ranging from one day to 70 days, with annual interest
rates ranging from 6.20% to 6.45%. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations -- The Combination" and
"-- Liquidity and Capital Resources."


                                DIVIDEND POLICY


     Following consummation of the offering, we currently anticipate paying
quarterly cash dividends on our common stock. Subject to attaining earnings
sufficient to pay such dividends and meet our other cash needs, our Board of
Directors currently intends to declare and pay an initial quarterly dividend of
$.06 per share of common stock payable October 16, 2000 to holders of record on
September 29, 2000. We expect cash flow from operations to be sufficient to fund
this dividend. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations."


     The declaration, amount and payment of dividends are at the discretion of
our Board of Directors and will depend upon our results of operations, financial
condition, cash requirements for our business, future prospects and other
factors determined to be relevant by our Board of Directors, as well as the
effect of any restrictive covenants in our credit agreements and debt
instruments. We cannot assure you that dividends will be paid in the future nor
can we assure you as to the amount of any dividends.

<PAGE>   21

                                    DILUTION


     If you invest in our common stock, your interest will be diluted to the
extent of the difference between the public offering price per share of our
common stock and the net tangible book value per share of our common stock after
the offering. Prior to the closing of the offering, Phillips will exchange its
member interest in Field Services LLC for our common stock. As a result, all
book value determinations reflect minority interest prior to the offering as
stockholders' equity. We calculate net book value per share by dividing the net
assets (total assets less liabilities) by the number of shares outstanding
before the offering. We calculate net tangible book value per share by dividing
the net tangible assets (total assets less liabilities and net intangible
assets) by the number of shares of common stock outstanding before the offering.



     Our net book value and net tangible book value as of March 31, 2000 were
approximately $16.06 and $10.82 per share, respectively. Without taking into
account any changes in net book value or net tangible book value after March 31,
2000, other than to give effect to the offering (at an assumed initial public
offering price per share of $21.00), the application of the estimated net
proceeds from the offering and deferred tax adjustments to intangibles, the pro
forma net book value of the common stock as of March 31, 2000 would have been
approximately $2,357.4 million, or $16.76 per share, and the pro forma net
tangible book value of the common stock as of such date would have been
approximately $1,894.8 million, or $13.47 per share. Assuming the offering had
occurred at March 31, 2000, an immediate increase in net book value of $.70 per
share to the existing stockholders and an immediate pro forma dilution of $4.24
per share to new investors would have occurred. The following table shows the
effect of the offering as if the offering had occurred at March 31, 2000 and
illustrates the immediate increase in pro forma net tangible book value of $2.65
per share to the existing stockholders and an immediate pro forma dilution of
$7.53 per share to new investors:

</TABLE>



     The foregoing table assumes the underwriters do not exercise their
overallotment option, and it does not reflect restricted stock awards for
approximately 110,500 shares of common stock expected to be issued concurrently
with the offering. Assuming all the restricted stock awards are granted, pro
forma net tangible book value per share would decrease $.01 per share to $13.46
per share.



     The following table shows, on a pro forma as adjusted basis at March 31,
2000, the number of shares of common stock owned and the average price paid per
share by the existing stockholders (based on net book value) and by new
investors purchasing common stock from us in the offering:

     The following table sets forth the total capitalization of our company as
of March 31, 2000:

     - on a historical basis; and

        - the merger of the subsidiary of Phillips that indirectly holds
          Phillips' minority interest into our company concurrently with the
          offering and the resulting issuance of shares of our common stock to
          Phillips; and



        - the sale of 26,300,000 shares of our common stock in the offering and
          the application of the estimated net proceeds from the offering.

                       SELECTED HISTORICAL AND PRO FORMA
                       COMBINED FINANCIAL AND OTHER DATA

     The following table sets forth selected historical financial and other data
for the Predecessor Company. The historical income statement data and cash flow
data for each of the three years ended December 31, 1999 and the historical
balance sheet data as of December 31 in each of those three years have been
derived from the Predecessor Company's audited historical financial statements.
The historical financial information for 1995 and 1996 and the three months
ended March 31, 1999 and 2000 is derived from unaudited financial statements.
The historical data set forth below relates only to the Predecessor Company and
does not reflect the results of operations or financial condition of the
Phillips businesses transferred to us in the Combination. In addition, the
following table sets forth selected pro forma financial and other data, which
reflect the historical results of operations of the Predecessor Company,
adjusted for:

     - the acquisition of the midstream natural gas business of Phillips in the
       Combination;

     - the acquisition of Union Pacific Fuels;

     - incurrence of indebtedness to fund the cash distributions to Duke Energy
       and Phillips in connection with the Combination as described in
       "Management's Discussion and Analysis of Financial Condition and Results
       of Operations;"


     - the offering and the expected application of the estimated proceeds;


     - the transfer to our company of additional midstream natural gas assets
       acquired by Duke Energy prior to consummation of the Combination; and

     - the transfer to our company of the general partner of TEPPCO;

as if all had occurred as of January 1, 1999 for income statement purposes and
March 31, 2000 for balance sheet purposes. The data should be read in
conjunction with the financial statements and related notes and other financial
information appearing elsewhere in this prospectus. The pro forma data set forth
below are not necessarily indicative of results that may occur in the future.

          MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                           AND RESULTS OF OPERATIONS


     The following discussion details the material factors that affected our
historical and pro forma financial condition and results of operations in 1997,
1998 and 1999 and the three months ended March 31, 1999 and 2000. This
discussion should be read in conjunction with "Selected Historical and Pro Forma
Combined Financial and Other Data," "Additional Financial and Other Data" and
the historical and pro forma financial statements, and, in each case, the notes
related thereto, included elsewhere in this prospectus.



     Unless the context otherwise requires, the discussion of our business
contained in this section relates to the Predecessor Company on an historical
basis without giving effect to the Combination, the transfer to our company of
additional midstream natural gas assets acquired by Duke Energy or Phillips
prior to consummation of the Combination or the transfer to our company of the
general partner of TEPPCO from Duke Energy.


OVERVIEW

     We operate in the two principal business segments of the midstream natural
gas industry:

     - natural gas gathering, processing, transportation and storage, from which
       we generate revenues primarily by providing services such as compression,
       treating and gathering, processing, local fractionation, transportation
       of residue gas, storage and marketing. In 1999, approximately 72% of the
       Predecessor Company's operating revenues and approximately 93% of the
       Predecessor Company's gross margin were derived from this segment.

     - NGLs fractionation, transportation, marketing and trading, from which we
       generate revenues from transportation fees, market center fractionation
       and the marketing and trading of NGLs. In 1999, approximately 28% of the
       Predecessor Company's operating revenues and approximately 7% of the
       Predecessor Company's gross margin were from this segment.

     Our certificate of incorporation limits the scope of our business to the
midstream natural gas industry in the United States and Canada, the marketing of
NGLs in Mexico and the transportation, marketing and storage of other petroleum
products, unless otherwise approved by our Board of Directors and Duke Energy
(so long as it owns a majority of our outstanding common stock). This limitation
in scope is not currently expected to materially impact the results of our
operations.

     EFFECTS OF COMMODITY PRICES

     In 1999, approximately 59% of the Predecessor Company's gross margin was
generated by arrangements that are commodity price sensitive and 41% of the
Predecessor Company's gross margin was generated by fee-based arrangements.
Because the gross margin of Phillips' midstream gas business is more heavily
weighted towards arrangements that are commodity price sensitive, as a result of
the Combination the portion of our gross margin generated by fee-based
arrangements has decreased. For example, in January, 2000, after giving effect
to the Combination, approximately 28% of our gross margin was generated by
fee-based arrangements.

     The midstream natural gas industry has been cyclical, with the operating
results of companies in the industry significantly affected by the prevailing
price of NGLs, which in turn generally is correlated to the price of crude oil.
Although the prevailing price of natural gas has less short-term significance to
our operating results than the price of NGLs, in the long term the growth of our
business depends on natural gas prices being at levels sufficient to provide
incentives and capital for producers to increase natural gas exploration and
production. In the past, the prices of NGLs and natural gas have been extremely
volatile.

                                       27
<PAGE>   29

     The following table sets forth financial data for the Predecessor Company
and the weighted average price of NGLs for each of the five years ended December
31, 1999 and demonstrates the relationship of our EBITDA to NGL prices. The
table below should not be viewed as indicating that the level of NGL prices is
the only factor affecting our results of operations. In addition to NGL prices,
our results of operations reflected in the table below were primarily affected
by:

     - fluctuations in raw natural gas volumes processed, including increases
       resulting from our acquisitions and additions;

     - the Predecessor Company's historical risk management activities; and

     - gain/(loss) on the sale of assets.

                                    [GRAPH]

     Note:  The weighted average NGL prices set forth in the table above are
            based on index prices from the Mont Belvieu and Conway market hubs
            that are weighted by our component and location mix for the years
            indicated.

     The gas gathering and processing price environment deteriorated between
1996 and 1997 as prices for NGLs decreased and prices for natural gas increased
from 1996 levels. Increases in worldwide crude oil supply and production in 1998
drove a steep decline in crude oil prices. NGL prices also declined sharply in
1998 as a result of the correlation between crude oil and NGL pricing. Natural
gas prices also declined during 1998 principally due to mild weather.

     The lower NGL and natural gas price environment experienced in 1998
prevailed during the first quarter of 1999. However, during the last three
quarters of 1999, NGL prices increased sharply as major crude oil exporting
countries agreed to maintain crude oil production at predetermined levels and
world demand for crude oil and NGLs increased. The lower crude oil and natural
gas prices in 1998 and early 1999 caused a significant reduction in the
exploration activities of U.S. producers, which in turn had a significant
negative effect on natural gas volumes gathered and processed in 1999.

     During the first quarter of 2000, the weighted average NGL price (based on
index prices from the Mont Belvieu and Conway market hubs that are weighted by
our component and location mix) was approximately $.50 per gallon. In the
near-term, we expect NGL prices to follow changes in crude oil prices generally,
which we believe will in large part be determined by the level of production
from major crude oil exporting countries and the demand generated by growth in
the world economy. In contrast, we believe that future natural gas prices will
be influenced by supply deliverability, the severity of winter weather and the
level of U.S. economic growth. We believe that weather will be the strongest
determinant of near-term natural gas prices. The price increases in crude oil,
NGLs and natural gas have spurred increased natural gas drilling activity. For
example, the number of actively drilling rigs in North America has increased by
approximately 65% from approximately

                                       28
<PAGE>   30

760 in February 1999 to more than 1,270 in February 2000. This drilling activity
increase is expected to have a positive effect on natural gas volumes gathered
and processed in the near term.

     EFFECTS OF OUR RAW NATURAL GAS SUPPLY ARRANGEMENTS

     Our results are affected by the types of arrangements we use to purchase
raw natural gas. We obtain access to raw natural gas and provide our midstream
natural gas services principally under three types of contracts:

     - Percentage-of-Proceeds Contracts -- Under these contracts (which also
       include percentage-of-index contracts), we receive as our fee a
       negotiated percentage of the residue natural gas and NGLs value derived
       from our gathering and processing activities, with the producer retaining
       the remainder of the value. These type of contracts permit us and the
       producers to share proportionately in price changes. Under these
       contracts, we share in both the increases and decreases in natural gas
       prices and NGL prices. In December 1999, after giving effect to the
       Combination approximately 57% of our gross margin was generated from
       percentage-of-proceeds or percentage-of-index contracts.

     - Fee-Based Contracts -- Under these contracts we receive a set fee for
       gathering, processing and/or treating raw natural gas. Our revenue stream
       from these contracts is correlated with our level of gathering and
       processing activity and is not directly dependent on commodity prices. In
       December 1999, after giving effect to the Combination, approximately 25%
       of our gross margin was generated from fee-based contracts.

     - Keep-Whole Contracts -- Under these contracts we gather raw natural gas
       from the producer for processing. After we process the raw natural gas,
       we are obligated to return to the producer residue gas with a Btu content
       equivalent to the Btu content of the raw natural gas gathered. As a
       result of our processing, NGLs are extracted from the raw natural gas
       resulting in a shrinkage in the Btu content of the natural gas. We market
       the NGLs and purchase natural gas at market prices in order to return to
       the producer residue gas with a Btu content equivalent to the Btu content
       of the raw natural gas gathered. Accordingly, under these contracts, we
       are exposed to increases in the price of natural gas and decreases in the
       price of NGLs. In December 1999, after giving effect to the Combination,
       approximately 15% of our gross margin was generated from keep-whole
       contracts.

     Our current mix of percentage-of-proceeds and percentage-of-index contracts
(where we are exposed to decreases in natural gas prices) and keep-whole
contracts (where we are exposed to increases in natural gas prices)
significantly mitigates our exposure to increases in natural gas prices, while
retaining our exposure to changes in NGL prices.

     We prefer to enter into percentage-of-proceeds type supply contracts
(including percentage-of-index contracts). We believe this type of contract
provides the best alignment with our producers and represents the best
risk/reward profile for the capital we employ. Notwithstanding this preference,
we also recognize from a competitive viewpoint that we will need to offer
keep-whole contracts to attract certain supply to our systems. We also employ a
fee-type contract, particularly where there is treating and/or transportation
involved. Our contract mix and, accordingly, our exposure to natural gas and NGL
prices may change as a result of changes in producer preferences, our expansion
in regions where some types of contracts are more common and other market
factors.

     Based upon the combined company's portfolio of supply contracts in 1999,
and excluding the effect of our commodities risk management program, an increase
of $.01 per gallon in the price of NGLs and $.10 per million Btus in the average
price of natural gas throughout such period would have resulted in changes in
pre-tax net income of approximately $24 million and ($1) million, respectively.

     OTHER FACTORS THAT HAVE SIGNIFICANTLY AFFECTED OUR RESULTS

     Our results of operations also are correlated with increases and decreases
in the volume of raw natural gas that we put through our system, which we refer
to as throughput volume, and the percentage of capacity at which our processing
facilities operate, which we refer to as our asset utilization rate. Throughput
volumes and asset utilization rates generally are driven by production on a
regional basis and more broadly by demand for residue natural gas and NGLs.


     Risk management, which has been directed by Duke Energy's centralized
program for controlling, managing and coordinating its management of risks, also
has affected our results of operations, particularly in 1999 and the first
quarter of 2000. Our 1999 and first quarter 2000 results of operations include
hedging losses of $34.0 million and $46.7 million, respectively. After the
Combination, we will direct our risk management activities independently of Duke
Energy, with goals, policies and procedures that are different from those of
Duke Energy. See " -- Quantitative and Qualitative Disclosure about Market
Risks."


     In addition to market factors and production, our results have been
affected by our acquisition strategy, including the timing of acquisitions and
our ability to integrate acquired operations and achieve operating synergies.

THE COMBINATION


     On March 31, 2000, we combined the gas gathering, processing, marketing and
NGLs businesses of Duke Energy and Phillips. In connection with the Combination,
Phillips transferred all of its interest in its subsidiaries that conducted its
midstream natural gas business to Field Services LLC, our subsidiary formed in
December of 1999 to hold all of Duke Energy's gas gathering and processing
business. In connection with the Combination, Duke Energy and Phillips also
transferred to Field Services LLC additional midstream natural gas assets
acquired by Duke Energy or Phillips prior to consummation of the Combination,
including Mid-Continent gathering and processing assets of Conoco and Mitchell
Energy. In addition, concurrently with the Combination, we obtained by transfer
from Duke Energy the general partner of TEPPCO. In exchange for the asset
contribution, Phillips received 30.3% of the member interests in Field Services
LLC, with Duke Energy indirectly, through us, holding the remaining 69.7% of the
outstanding member interests. In connection with the closing of the Combination,
Field Services LLC borrowed approximately $2.8 billion in the commercial paper
market and made one-time cash distributions (including reimbursements for
acquisitions) of approximately $1.5 billion to Duke Energy and approximately
$1.2 billion to Phillips. See "-- Liquidity and Capital Resources." The
Combination is accounted for as a purchase of the Phillips midstream natural gas
business.



     Concurrently with the completion of the offering of our common stock, the
subsidiary of Phillips that indirectly holds Phillips' interest in Field
Services LLC will be merged into our company, and we will issue shares of our
common stock to Phillips. After the merger and completion of the offering of our
common stock, Duke Energy and Phillips together will own approximately 81.24% of
our outstanding common stock. The exact allocation between Duke Energy and
Phillips of shares of our common stock will be determined by the average of the
closing prices of our common stock on its first five trading days on the New
York Stock Exchange Composite Tape. Assuming that the five-day average price is
the same as the assumed initial public offering price, following the offering,
Duke Energy will own approximately 58.65% and Phillips will own approximately
22.59% of our outstanding common stock. Although the exact allocation may vary,
Duke Energy will, in all events, continue to control our company through its
share ownership and representation on our Board of Directors.



     The Combination was accounted for as a purchase business combination in
accordance with Accounting Principles Board Opinion (APB) No. 16, "Accounting
for Business Combinations". The Predecessor Company was the acquiror of
Phillips' midstream natural gas business in the Combination. The purchase price
allocation associated with the Phillips assets is preliminary. Currently there
are no pre-acquisition contingent liabilities reflected in the purchase price
allocation. The final purchase price allocation is subject to adjustment pending
gathering of additional information regarding certain pre-acquisition contingent
liabilities and


                                       30
<PAGE>   32

obtaining appraisals. The effect of any pre-acquisition contingencies is not
expected to have a material effect on our operating results, liquidity or
financial condition.

COMBINED RESULTS OF OPERATIONS


     The following is a discussion of the combined operating revenues and cost
of sales of our company giving effect to the Combination, the transfer to our
company of the midstream natural gas businesses acquired by Duke Energy and
Phillips prior to the consummation of the Combination and the acquisition of
Union Pacific Fuels as if each transaction occurred on January 1, 1995.


     This discussion should be read in conjunction with the historical and pro
forma financial statements and related notes and other financial information
appearing elsewhere in this prospectus. The data on which this discussion is
based should not be considered indicative of:

     - the actual results that would have been realized had the Combination and
       the acquisition of Union Pacific Fuels actually occurred on January 1,
       1995; or

     - the results of our future operations.

     THREE MONTHS ENDED MARCH 31, 2000 COMPARED WITH THREE MONTHS ENDED MARCH
31, 1999

     Operating Revenues. Operating revenues increased $1,091.8 million, or 114%,
from $959.0 million to $2,050.8 million. Of this increase, approximately $1,000
million was due to increases in commodity prices, as weighted average NGL
prices, based on our component product mix, were approximately $.28 per gallon
higher and natural gas prices were approximately $.77 per million Btus higher.
Acquisitions and plant expansions contributed approximately $90 million to the
revenue increase. NGL production during the first quarter increased 33,000
barrels per day, or 9%, from 382,000 barrels per day to 415,000 barrels per day,
and natural gas transported and/or processed increased 0.9 trillion Btus per
day, or 13%, from 7.0 trillion Btus per day to 7.9 trillion Btus per day.
Included in first quarter 2000 operating revenues is a $46.7 million loss on
hedging activity compared to a $4.0 million gain in first quarter 1999.

     Cost of Sales. Costs of natural gas and petroleum products increased $941.3
million, or 124%, from $761.8 million to $1,703.1 million. This increase was
primarily due to the interaction of our gas and NGL purchase contracts with
higher commodity prices. Higher natural gas and NGLs throughput associated with
our acquisitions and plant expansions also increased product purchase costs.


     1999 COMPARED WITH 1998


     Operating Revenues. Operating revenues increased $1,271.9 million, or 30%,
from $4,302.7 million to $5,574.6 million. Of this increase, approximately
$1,100 million was due to increases in commodity prices, as weighted average NGL
prices, based on our component product mix, were approximately $.08 per gallon
higher and natural gas prices were approximately $.16 per million Btus higher.
Our acquisitions and plant expansions also contributed to this increase. NGLs
production during 1999 increased 27,000 barrels per day, or 7%, from 373,000
barrels per day to 400,000 barrels per day, and natural gas transported and/or
processed remained essentially unchanged at 7.3 trillion Btus per day. The
recovery of commodity prices during the last three quarters of 1999 encouraged
exploration and production activity, which positively affected existing
throughput volumes. Included in 1999 operating revenues is approximately $34.0
million of loss on hedging activity. There were no significant hedging
activities in 1998. See "-- Quantitative and Qualitative Disclosure About Market
Risks."

     Cost of Sales. Costs of natural gas and petroleum products increased
$1,027.3 million, or 29%, from $3,527.5 million to $4,554.8 million. This
increase primarily was due to the interaction of our gas and NGL purchase
contracts with higher commodity prices.

                                       31
<PAGE>   33


     1998 COMPARED WITH 1997


     Operating Revenues. Operating revenues decreased $466.4 million, or 10%,
from $4,769.1 million to $4,302.7 million. Lower commodity prices resulted in an
approximately $800 million reduction of operating revenues, as weighted average
NGL prices, based on our component product mix, were approximately $.09 per
gallon lower and natural gas prices were unchanged. Partially offsetting this
decrease was approximately $22 million additional revenues attributable to our
fourth quarter 1997 acquisition of Highlands Gas Partners and approximately $300
million additional revenues attributable to our increased NGL trading and
marketing activities. Natural gas transported and/or processed decreased .2
trillion Btus per day, or 3%, from 7.5 trillion Btus per day to 7.3 trillion
Btus per day. This decrease was primarily the result of reduced exploration and
production activity caused by depressed commodity prices. This decrease was
offset by an increase in NGLs production of 15,000 barrels per day, or 4%, from
358,000 barrels per day to 373,000 barrels per day. NGLs production growth
primarily was the result of the Highlands Gas Partners acquisition and the
restart of a processing facility in the fourth quarter of 1997.

     Cost of Sales. Cost of natural gas and petroleum products decreased $271.0
million, or 7%, from $3,798.5 million to $3,527.5 million. This decrease
primarily was due to declining NGL prices. Increased NGL trading and marketing
activity partially offset this decrease.

HISTORICAL RESULTS OF OPERATIONS

     The following is a discussion of the historical results of operations of
the Predecessor Company.

  THREE MONTHS ENDED MARCH 31, 2000 COMPARED WITH THREE MONTHS ENDED MARCH 31,
  1999

     Operating Revenues. Operating revenues increased $1,116.2 million, or 333%,
from $335.0 million to $1,451.2 million. Operating revenues from the sale of
natural gas and petroleum products accounted for $1,415.5 million of the total
and $1,110.3 million of the increase. Of this increase, approximately $425
million is related to the March 31, 1999 acquisition of Union Pacific Fuels.
Increased NGL trading and marketing activity also contributed to the increase.
NGL production during the first quarter increased 123,600 barrels per day, or
115%, from 107,600 barrels per day to 231,200 barrels per day, and natural gas
transported and/or processed increased 2.6 trillion Btus per day, or 76%, from
3.4 trillion Btus per day to 6.0 trillion Btus per day. Of the 123,600 barrels
per day increase, the Union Pacific Fuels acquisition contributed 100,600
barrels per day, with the combination of our Wilcox plant expansion, completion
of our Mobile Bay Plant and the acquisition of Koch's South Texas assets
accounting for the remainder of the increase. Of the 2.6 trillion Btus per day
increase, the Union Pacific Fuels acquisition contributed 2.0 trillion Btus per
day, with the

                                       32
<PAGE>   34

combination of other acquisitions, plant expansions and completions accounting
for the balance of the increase.

     Commodity prices also contributed to higher revenues. Weighted average NGL
prices, based on our component product mix, were approximately $.27 per gallon
higher and natural gas prices were approximately $.77 per million Btus higher
for the first quarter. These price increases yielded average prices of $.50 per
gallon and $2.52 per million Btus, respectively, as compared with $.23 per
gallon and $1.75 per million Btus for the first quarter of 1999. Revenues
associated with gathering, transportation, storage, processing fees and other
increased $5.9 million, or 20%, from $29.8 million to $35.7 million, mainly as a
result of the Union Pacific Fuels acquisition. A $46.7 million hedging loss in
the first quarter of 2000 offset total operating revenue increases. See
"-- Quantitative and Qualitative Disclosure About Market Risks."

     Costs and Expenses. Costs of natural gas and petroleum products increased
$1,006 million, or 369%, from $272.5 million to $1,278.5 million. This increase
was due to the Union Pacific Fuels acquisition (approximately $340 million), the
interaction of our natural gas and NGL purchase contracts with higher commodity
prices and increased trading and marketing activity.

     Operating and maintenance expenses increased $19.9 million, or 68%, from
$29.1 million to $49.0 million. Of this increase, approximately $13 million was
due to the Union Pacific Fuels acquisition. General and administrative expenses
increased $13.6 million, or 84%, from $16.1 million to $29.7 million. Of this
increase, $5.1 million was due to increased allocated corporate overhead from
our parent, Duke Energy. The remainder was associated with increased activity
resulting from the Union Pacific Fuels acquisition and increased fiscal year
2000 incentive compensation accruals.

     Depreciation and amortization increased $17.9 million, or 90%, from $20
million to $37.9 million. Of this increase, $15.2 million was due to the Union
Pacific Fuels acquisition. The remainder was due to ongoing capital expenditures
for well connections, facility maintenance/enhancements and acquisitions.

     Sale of Assets. Net (gain) loss on sales of assets decreased $4.1 million
from zero activity to a loss of $4.1 million. The loss was primarily the result
of the sale of the Westana joint venture investment.

     Equity Earnings. Equity earnings of unconsolidated affiliates increased
$3.5 million, or 106%, from $3.3 million to $6.8 million. This increase was
largely due to interests in joint ventures and partnerships acquired from Union
Pacific Fuels.

     Interest. Interest expense increased $2.1 million, or 17%, from $12.4
million to $14.5 million. This increase is primarily related to interest on
notes due to Duke Energy.

     Net Income. Net income increased $35.4 million from a loss of $8.5 million
to $26.9 million. This increase was largely the result of the acquisition of
Union Pacific Fuels and higher average NGL prices. The benefit of higher NGL
prices was partially offset by higher natural gas prices. A $46.7 million
pre-tax loss from hedging activities experienced during the first quarter of
2000 partially offset the increase.

     EBITDA. EBITDA for the natural gas gathering, processing, transportation
and storage segment increased $65.7 million from $36.0 million to $101.7
million. Of this increase, approximately $56 million was due to the acquisition
of Union Pacific Fuels and approximately $60 million was due to a $.27 per
gallon increase in average NGL prices. Additional increases were attributable to
the combination of our Wilcox plant expansion, completion of our Mobile Bay
plant and the acquisition of Koch's South Texas assets. These benefits were
offset by a $50.7 million decrease from hedging activities ($46.7 million loss
in 2000 compared to a $4.0 million gain in 1999) and approximately $6 million
due to a $.77 per million Btu increase in natural gas prices.

     EBITDA for the NGLs fractionation, transportation, marketing and trading
segment increased $23.8 million from $.7 million to $24.5 million due primarily
to NGL trading and marketing activity and the acquisition of Union Pacific
Fuels.

                                       33
<PAGE>   35

     1999 COMPARED WITH 1998

     Operating Revenues. Operating revenues increased $1,874.0 million, or 118%,
from $1,584.3 million to $3,458.3 million. Operating revenues from the sale of
natural gas and petroleum products accounted for $3,310.3 million of the total
and $1,841.2 million of the increase. Of this increase, approximately $1.0
billion was attributable to the March 31, 1999 acquisition of Union Pacific
Fuels. Increased NGL trading and marketing activity associated with the Union
Pacific Fuels acquisition also contributed to the increase. NGL production
during 1999 increased 82,000 barrels per day, or 75%, from 110,000 barrels per
day to 192,000 barrels per day. Of the 82,000 barrels per day increase, the
Union Pacific Fuels acquisition contributed 71,000 barrels per day, with the
combination of our Wilcox plant expansion, completion of our Mobile Bay Plant
and the acquisition of Koch's South Texas assets accounting for the remainder of
the increase. Raw natural gas transported and/or processed increased 1.5
trillion Btus per day, or 42%, from 3.6 trillion Btus per day to 5.1 trillion
Btus per day. The Union Pacific Fuels acquisition accounted for 1.4 trillion
Btus per day of the natural gas increase.

     Commodity prices also contributed to higher revenues. Weighted average NGL
prices, based on our component product mix, were approximately $.08 per gallon
higher and natural gas prices were approximately $.16 per million Btus higher
for 1999, yielding prices of $.34 and $2.27, respectively, as compared with $.26
and $2.11 in 1998. Revenues associated with gathering, transportation, storage,
processing fees and other increased $32.8 million, or 28%, from $115.2 million
to $148.0 million principally as a result of the Union Pacific Fuels
acquisition. Total operating revenue increases were offset by a $34.0 million
hedging loss in 1999. See "-- Quantitative and Qualitative Disclosure About
Market Risks."

     Costs and Expenses. Costs of natural gas and petroleum products increased
$1,627.2 million, or 122%, from $1,338.1 million to $2,965.3 million. This
increase was due primarily to the Union Pacific Fuels acquisition ($800
million), increased NGL trading and marketing activity and the interaction of
our natural gas and NGL purchase contracts with higher commodity prices.

     Operating and maintenance expenses increased $67.8 million, or 60%, from
$113.6 million to $181.4 million. Of this increase, approximately $65.0 million
was due to the Union Pacific Fuels acquisition. General and administrative
expenses increased $28.7 million, or 64%, from $45.0 million to $73.7 million.
This increase was due to a $7.0 million increase in allocated corporate overhead
from our parent, Duke Energy, and increases resulting from the Union Pacific
Fuels acquisition.

     Depreciation and amortization increased $55.2 million, or 73%, from $75.6
million to $130.8 million. Of this increase, $45.2 million was due to the Union
Pacific Fuels acquisition and the remainder was due to ongoing capital
expenditures for well connections, facility maintenance/enhancements and
acquisitions.

     Sale of Assets. Net (gain) loss on sales of assets decreased $36.2 million,
from a $33.8 million gain to a $2.4 million loss from 1998 to 1999. This
decrease was primarily the result of a $38.0 million gain recognized in 1998 on
the sale of two fractionators in Weld County, Colorado.

     Equity Earnings. Equity earnings of unconsolidated affiliates increased
$10.7 million, or 91%, from $11.8 million to $22.5 million. This increase was
largely due to interests in joint ventures and partnerships acquired from Union
Pacific Fuels in 1999.

     Interest. Interest expense of $52.9 million for 1999 remained almost
unchanged from 1998 and was principally related to interest on notes due to Duke
Energy.

     Net Income. Net income increased $41.3 million from $2.0 million to $43.3
million. This increase was largely the result of the acquisition of Union
Pacific Fuels and higher average NGL prices experienced during 1999. The benefit
of higher NGL prices was partially offset by higher natural gas prices. The
increase in net income was largely offset by a pre-tax gain of approximately
$38.0 million recognized on the sale of our Weld County fractionators in 1998
and a $34.0 million loss on hedging activity in 1999.

     EBITDA. EBITDA for the natural gas gathering, processing, transportation
and storage segment increased $122.9 million from $175.8 million to $298.7
million. Of the increase, approximately $110 million was due to the acquisition
of Union Pacific Fuels and $80.0 million was due to $.08 per gallon higher NGL
                                       34
<PAGE>   36

prices. Additional increases were recognized with the combination of our Wilcox
plant expansion, completion of our Mobile Bay Plant and the acquisition of
Koch's South Texas assets. These increases were offset by a $38.0 million gain
recognized in 1998 on the sale of the Weld County fractionators, hedging losses
in 1999 of $34.0 million, an approximately $5 million decrease due to $.16 per
million BTU increase in gas prices and a $7.0 million increase in allocated
corporate overhead from our parent, Duke Energy.

     EBITDA for the NGLs fractionation, transportation, marketing and trading
segment increased $30.6 million from $2.4 million to $33.0 million due primarily
to the acquisition of Union Pacific Fuels.

     1998 COMPARED WITH 1997

     Operating Revenues. Operating revenues decreased $217.5 million, or 12%,
from $1,801.8 million to $1,584.3 million. Operating revenues from the sale of
natural gas and petroleum products decreased $230.9 million, or 14%, from
$1,700.0 million to $1,469.1 million. This decrease was largely due to commodity
prices, as weighted average NGLs prices, based on our component product mix,
were approximately $.09 per gallon lower and natural gas prices were
approximately $.48 per MMBtu lower for 1998, yielding prices of $.26 and $2.11,
respectively, as compared with $.35 and $2.59 in 1997. This NGL price decline
was partially offset by an increase in NGL production during 1998 of 2,000
barrels per day, or 2%, from 108,000 barrels per day to 110,000 barrels per day,
and by an increase in natural gas gathered, transported and/or processed of .2
trillion Btus per day, or 6%, from 3.4 trillion Btus per day to 3.6 trillion
Btus per day, due to increased production on existing facilities. Revenues
associated with gathering, transportation, storage, processing fees and other
increased $13.4 million, or 13%, from $101.8 million to $115.2 million. This
increase was principally the result of increased volumes.

     Costs and Expenses. Costs of natural gas and petroleum products decreased
$130.0 million, or 9%, from $1,468.1 million to $1,338.1 million. This decrease
was primarily due to declining NGL prices. The NGL price decline was partially
offset by increases in system throughput volumes.

     Operating and maintenance expenses increased $9.3 million, or 9%, from
$104.3 million to $113.6 million. This increase was primarily due to higher
property tax accruals associated with property additions and other inflationary
factors. General and administrative expenses increased $8.9 million, or 25%,
from $36.0 million to $44.9 million. This increase was due primarily to an
increase in the incentive bonus accrual and internal growth.

     Depreciation and amortization increased $7.9 million, or 12%, from $67.7
million to $75.6 million. This increase was primarily due to ongoing capital
expenditures for well connections, facility maintenance/enhancements and
acquisitions.

     Sales of Assets. Net (gain) loss on sales of assets increased $33.6
million, from a $.2 million gain to a $33.8 million gain from 1997 to 1998. This
increase was primarily due to a $38.0 million gain recognized in March 1998 on
the sale of the Weld County fractionators.

     Equity Earnings. Equity earnings of unconsolidated affiliates increased
$2.0 million, or 20%, from $9.8 million to $11.8 million. This increase was
largely due to increased earnings from Dauphin Island Gathering and Main Pass
Oil in the offshore region.

     Interest. Interest expense increased $1.3 million, or 3%, from $51.1
million to $52.4 million. Interest expense reflects interest on notes due to
affiliated companies.

     Net Income. Net income decreased $49.2 million, or 96%, from $51.2 million
to $2.0 million. This decrease was largely the result of substantially lower
commodity prices. A pre-tax gain of approximately $38.0 million recognized on
the sale of our Weld County fractionators in March 1998 partially offset the
impact of the sharp NGL price decline.

     EBITDA. EBITDA for the natural gas gathering, processing, transportation
and storage segment decreased $64.0 million from $239.8 million to $175.8
million. Of the decrease, approximately $80 million was due to $.09 per gallon
lower NGL prices and approximately $18 million was due to increased operating
and general and administrative expenses resulting from higher property tax
accruals associated with property
                                       35
<PAGE>   37

additions, an increase in the incentive bonus accrual and internal growth. These
decreases were partially offset by a $38.0 million gain recognized in March 1998
on the sale of the Weld County fractionators.

     EBITDA for the NGLs fractionation, transportation, marketing and trading
segment increased $2.8 million from $(.4) million to $2.4 million due to
increased trading and marketing activity.

ENVIRONMENTAL CONSIDERATIONS

     Environmental expenditures are expensed or capitalized as appropriate,
depending upon the future economic benefit. Historically these expenditures have
been between $5 million and $15 million annually except for those environmental
liabilities identified with the acquisition of Union Pacific Fuels of
approximately $63 million. The Union Pacific Fuels environmental liabilities
associated with soil and groundwater contamination were transferred to a third
party at a cost of approximately $48 million.

     The outlook for environmental spending, both capitalized and expensed, is
not expected to change materially from historical levels of $5 to $15 million
annually.

LIQUIDITY AND CAPITAL RESOURCES

     LIQUIDITY PRIOR TO THE COMBINATION

     The Predecessor Company's capital investments and acquisitions have been
financed by cash flow from operations and non-interest bearing advances from
Duke Energy or its subsidiaries under various arrangements. Under Duke Energy's
centralized cash management system, Duke Energy deposited sufficient funds in
our bank accounts for us to meet our daily obligations and withdrew excess funds
from those accounts. Advances were offset by cash provided by operations to
yield net advances from Duke Energy which were included in the historical
consolidated balance sheets and statements of cash flows of the Predecessor
Company. In 1999, the Predecessor Company had notes to and advances from Duke
Energy which were terminated in connection with the Combination.

     FINANCING TRANSACTIONS IN CONNECTION WITH THE COMBINATION

     In connection with the Combination, all advances from Duke Energy were
capitalized to equity and all advances from Phillips were capitalized.


     On March 31, 2000, Field Services LLC entered into a $2.8 billion credit
facility with several financial institutions. The credit facility will be used
as the liquidity backstop to support a commercial paper program. On April 3,
2000 Field Services LLC borrowed approximately $2.8 billion in the commercial
paper market to fund the one-time cash distributions (including reimbursements
for acquisitions) of approximately $1.5 billion to Duke Energy and approximately
$1.2 billion to Phillips and to cover working capital requirements. At April 30,
2000 our outstanding commercial paper had maturities ranging from one day to 70
days and had annual interest rates between 6.20% and 6.45%. At no time will the
amount of our outstanding commercial paper exceed the available amount under the
credit facility. The credit facility matures on March 30, 2001 and borrowings
bear interest at a rate equal to, at our option, either (1) LIBOR plus .50% per
year for the first 90 days following the closing of the credit facility and
LIBOR plus .625% per year thereafter or (2) the higher of (a) the Bank of
America prime rate and (b) the Federal Funds rate plus .50% per year. Upon
completion of the offering, Duke Energy Field Services Corporation will assume
Field Services LLC's obligations under the facility.


     Effective April 4, 2000, Field Services LLC entered into a $100 million
revolving credit agreement with Duke Capital Corporation, an indirect,
wholly-owned subsidiary of Duke Energy. The revolving credit agreement will be
used for short-term financing requirements. At April 30, 2000, there were no
amounts outstanding under this facility. The agreement terminates on May 31,
2000, and bears interest at the Bank of America prime rate.


     Proceeds of the offering will be used to repay a portion of our outstanding
commercial paper, and the credit facility will be permanently reduced by the
amount of such proceeds. The amount available under the


                                       36
<PAGE>   38


credit facility and corresponding commercial paper program will be further
reduced by the amount, if any, of long-term debt we may issue, but in no event
will the credit facility be reduced to below $1.0 billion. Upon completion of
the offering and application of the net proceeds, we expect to have outstanding
$2.1 billion of indebtedness. The debt levels reflected in the pro forma
combined financial statements are based upon the indebtedness we anticipate
having outstanding upon consummation of the financing transactions described
above and the offering. In the future, our debt levels will vary depending on
our liquidity needs, capital expenditures and cash flow.


     Based on current and anticipated levels of operations, we believe that our
cash on hand and cash flow from operations, combined with borrowings available
under the commercial paper program and credit facilities, will be sufficient to
enable us to meet our current and anticipated cash operating requirements and
working capital needs for the next year. Actual capital requirements, however,
may change, particularly as a result of any acquisitions that we may make. Our
ability to meet current and anticipated operating requirements will depend on
our future performance.

     CAPITAL EXPENDITURES

     Our capital expenditures consist of expenditures for acquisitions and
construction of additional gathering systems, processing plants, fractionators
and other facilities and infrastructure in addition to well connections and
repairs and maintenance of our existing facilities. Our capital expenditure
budget for well connections and repair and maintenance of our existing
facilities in 2000 is approximately $175 million, of which approximately $25
million was spent in the three months ended March 31, 2000.


     On March 31, 2000, Field Services LLC acquired gathering and processing
assets located in central Oklahoma from Conoco and Mitchell Energy. Field
Services LLC paid cash of $99.5 million, and exchanged its interest in certain
gathering and marketing joint ventures located in southeast Texas having a total
net book value of approximately $42 million as consideration for these assets.


     Our level of capital expenditures for acquisitions and construction depends
on many factors, including industry conditions, the availability of attractive
acquisition candidates and construction projects, the level of commodity prices
and competition. We expect to finance our capital expenditures with our cash on
hand, cash flow from operations and borrowings available under our commercial
paper program, our credit facility or other available sources of financing.

     CASH FLOWS


     Net cash provided by operating activities for the Predecessor Company for
the three months ended March 31, 2000 improved to $186.2 million from $24.4
million for the same period in 1999, primarily due to higher commodity prices
and acquisitions. Net cash used in investing activities by the Predecessor
Company was $111.4 million for the three months ended March 31, 2000 compared to
$1,458.2 million for the same period in 1999. Acquisitions of the Conoco and
Mitchell Energy assets in 2000 and the Union Pacific Fuels assets in 1999 were
the primary uses of the invested cash. The net cash used in investing activities
was financed through operating activities, advances from Duke Energy and
proceeds from the issuance of short-term debt.


     Net cash provided by operating activities for the Predecessor Company in
1999 improved to $173.1 million from $40.4 million in 1998, primarily due to
higher commodity prices and acquisitions. Net cash used in investing activities
by the Predecessor Company was $1,571.4 million for 1999 compared to $203.6
million for 1998, of which $1,456.5 million was used for acquisitions and the
remainder was used principally for capital expenditures. The net cash used in
investing activities was financed through operating activities, advances from
Duke Energy and proceeds from the issuance of short-term debt.

     Net cash provided by operating activities for the Predecessor Company was
$40.4 million for 1998 compared to $173.4 million for 1997. This decrease was
primarily due to the reduction of trade accounts payable to producers for the
purchase of raw natural gas at purchase prices lower than those in 1997. Net
cash used in investing activities by the Predecessor Company in 1998 increased
to $203.6 million from $138.0 mil-

                                       37
<PAGE>   39

lion in 1997. In 1998, $185.5 million was used for capital expenditures and
$84.9 million was used for investments in affiliates. The net cash used in
investing activities was provided by operating activities and advances from Duke
Energy.

QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISKS

     COMMODITY PRICE RISK

     We are subject to significant risks due to fluctuations in commodity
prices, primarily with respect to the prices of NGLs that we own as a result of
our processing activities. Based upon the Predecessor Company's portfolio of
supply contracts in 1999, without giving effect to hedging activities that would
reduce the impact of commodity price decreases, a decrease of $.01 per gallon in
the price of NGLs and $.10 per million Btus in the average price of natural gas
throughout 1999 would have resulted in changes in pre-tax net income of
approximately $(15) million and $5 million, respectively. Based upon the
combined company's portfolio of supply contracts in 1999, and excluding the
effects of our commodities risk management program, similar commodities price
changes in 1999 would have resulted in changes in pre-tax net income of
approximately $(24) million and $1 million, respectively.

     Commodity derivatives such as futures and swaps are available to reduce
such exposure to fluctuations in commodity prices. Gains and losses related to
commodity derivatives are recognized in income when the underlying hedged
physical transaction closes, and such gains and losses are included in sales of
natural gas and petroleum products in our statement of income.

     Natural gas and crude oil futures, which are used to hedge NGLs prices,
involve the buying and selling of natural gas and crude oil for future delivery
at a fixed price. Over-the-counter swap agreements require us to receive or make
payments on the difference between a specified price and the actual price of
natural gas or crude oil.

     Historically, the Predecessor Company's commodity price risk was managed by
Duke Energy's centralized program for controlling, managing and coordinating its
risk management activities. Under this program, the Predecessor Company used
futures and swaps to manage margins on offsetting fixed-price purchase or sale
commitments for physical quantities of natural gas and NGLs. Historically,
futures and swaps conducted through Duke Energy were handled through Duke Energy
Trading and Marketing, LLC, a partnership in which Duke Energy owns a 60%
interest. Under this arrangement, the Predecessor Company did not experience
margin requirements.

     At December 31, 1998 and 1999 the Predecessor Company (through Duke Energy)
had outstanding futures and swaps for an absolute notional contract quantity of
10.92 and 7.8 Bcf of natural gas and an absolute notional contract quantity of
59,000 and 32,764,000 barrels of crude oil, respectively, both of which were
intended to offset the risk of price fluctuations under fixed-price commitments
for delivering and purchasing natural gas and NGLs, respectively. The gains,
losses and costs related to those financial instruments that qualify as a hedge
are not recognized until the underlying physical transaction occurs. At December
31, 1998 and 1999, the Predecessor Company had current unrecognized net gains
(losses) of $1.8 million and $(63.5) million, respectively, related to commodity
instruments. All unrecognized gains and losses at March 31, 2000, the date of
the Combination, remain with Duke Energy and will not have an impact on our
company's future earnings.

     Losses relating to hedging with commodity derivatives included in the
Predecessor Company's statement of income equaled $34.0 million for 1999. There
were no corresponding losses in 1997 or 1998. For the three months ended March
31, 1999 and 2000, the Predecessor Company recorded a hedging gain of $4.0
million and a hedging loss of $46.7 million, respectively.

     After the Combination, we began directing our risk management activities
independently of Duke Energy.

     We intend to use commodity-based derivative contracts to reduce the risk in
our overall earnings and cash flow with the primary goals of:

                                       38
<PAGE>   40

     - maintaining minimum cash flow to fund debt service, dividends, and
       maintenance type capital projects;

     - avoiding disruption of our growth capital and value creation process; and

     - retaining a high percentage of the potential upside relating to commodity
       price increases.

     We implemented a risk management policy that provides guidelines for
entering into contractual arrangements to manage our commodity price exposure.
Our risk management committee has ongoing responsibility for the content of this
policy and has principal oversight responsibility for compliance with the policy
framework by ensuring proper procedures and controls are in place.

     In general, we will look to provide downside protection to our business
activities while retaining most of the upside potential by using floors and
other similar hedging structures. These structures will typically require the
payment of a premium to protect the downside while retaining exposure to the
upside. Historically, NGLs and related commodity products have shown a mean
reverting tendency to long term average prices, which implies that supply and
demand for products balance over cycles. Therefore, we may choose to forego
price upside in favor of a known, hedged cash flow position as prices rise
significantly above historical levels and depending upon existing market
drivers.

     An active forward market for hedging of NGL products is not normally
available for hedging a significant amount of our NGL production beyond a one to
three month time horizon. With an anticipated hedging horizon of up to 12
months, crude oil derivatives, which historically have had a high correlation
with NGL prices, will typically be the mechanism used for longer-term price risk
management.

     As of March 31, 2000, the existing commodity positions under the Duke
Energy centralized program were transferred to Duke Energy. In establishing its
initial independent commodity risk management position on April 1, 2000, the
Company acquired a portion of Duke Energy's existing commodity derivatives held
for non-trading purposes. The absolute notional contract quantity of the
positions acquired was 4,607,000 barrels of crude oil. Such positions were
acquired at market value.

     INTEREST RATE RISK


     Prior to the Combination, our subsidiaries had no material interest rate
risk associated with debt used to finance our operations due to limited third
party borrowings. After completion of the offering, we expect to have
approximately $2.1 billion outstanding under a commercial paper program. As a
result, we are exposed to market risks related to changes in interest rates. In
the future, we intend to manage our interest rate exposure using a mix of fixed
and floating interest rate debt. Following the application of the net proceeds
of the offering, and assuming none of our outstanding commercial paper is
refinanced with long-term fixed rate debt, an increase of .5% in interest rates
would result in an increase in annual interest expense of approximately $10.5
million.


     FOREIGN CURRENCY RISK

     Currently we have no material foreign currency exposure.

ACCOUNTING PRONOUNCEMENTS

     In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133, "Accounting for Derivative Instruments
and Hedging Activities" (SFAS 133). SFAS 133 establishes standards for
derivative instruments, including certain derivative instruments embedded in
other contracts (collectively referred to as derivatives) and for hedging
activities. SFAS 133 requires that an entity recognize all derivatives as either
assets or liabilities in the statement of financial position and measure those
instruments at fair value. If certain conditions are met, a derivative may be
specifically designated as:

     - a hedge of the exposure to changes in the fair value of a recognized
       asset or liability or an unrecognized firm commitment;

     - a hedge of the exposure to variable cash flows of a forecasted
       transaction; or
                                       39
<PAGE>   41

     - a hedge of the foreign currency exposure of a net investment in a foreign
       operation, an unrecognized firm commitment, an available-for-sale
       security, or a foreign-currency-denominated forecasted transaction.

     The accounting for changes in the fair value of a derivative (gains and
losses) depends on the intended use of the derivative and the resulting
designation. We are required to adopt SFAS 133 on January 1, 2001. We have not
completed the process of evaluating the impact that will result from adopting
SFAS 133.

YEAR 2000

     We did not experience any disruption to our operations resulting from the
transition to the year 2000. We completed our year 2000 readiness program in
November 1999. Our systems will continue to be monitored throughout the year.
The total cost of the program, including costs such as consulting and contract
costs, was approximately $2.2 million. These costs exclude replacement systems
that, in addition to being year 2000 ready, provided significantly enhanced
capabilities that benefit operations in future periods.

                                    BUSINESS

OUR BUSINESS

     The midstream natural gas industry is the link between exploration and
production of raw natural gas and the delivery of its components to end-use
markets. We operate in the two principal segments of the midstream natural gas
industry:

     - natural gas gathering, processing, transportation, marketing and storage;
       and

     - NGL fractionation, transportation, marketing and trading.

     We are the largest gatherer of raw natural gas, based on wellhead volume,
and the largest producer of NGLs in North America. We are also one of the
largest marketers of NGLs in North America. In 1999:

     - we gathered and/or transported an average of approximately 7.3 billion
       cubic feet per day of raw natural gas;

     - we produced an average of approximately 400,000 barrels per day of NGLs;
       and

     - we marketed and traded an average of approximately 486,000 barrels per
       day of NGLs.

     During 1999, our natural gas gathering, processing, transportation,
marketing and storage segment produced $981.5 million of gross margin and $583.1
million of EBITDA, excluding general and administrative expenses, and our NGL
fractionation, transportation, marketing and trading segment produced $38.3
million of gross margin and $38.1 million of EBITDA, excluding general and
administrative expenses.

     We gather raw natural gas through gathering systems located in seven major
natural gas producing regions: Permian Basin, Mid-Continent, East Texas-Austin
Chalk-North Louisiana, Onshore Gulf of Mexico, Rocky Mountains, Offshore Gulf of
Mexico and Western Canada. Our gathering systems consist of approximately 57,000
miles of gathering pipe, with approximately 38,000 active connections to
producing wells.

     Our natural gas processing operations involve the separation of raw natural
gas gathered both by our gathering systems and by third-party systems into NGLs
and residue gas. We process the raw natural gas at our 70 owned and operated
plants and at 13 third-party operated facilities in which we hold an equity
interest.

     The NGLs separated from the raw natural gas by our processing operations
are either sold and transported as NGL raw mix or further separated through a
process known as fractionation into their individual components (ethane,
propane, butanes and natural gasoline) and then sold as components. We
fractionate NGL raw mix at our 12 owned and operated processing facilities and
at two third-party operated fractionators located on the Gulf Coast in which we
hold an equity interest.

     We sell NGLs to a variety of customers ranging from large, multi-national
petrochemical and refining companies to small regional retail propane
distributors. Substantially all of our NGL sales are made at market-based
prices, including approximately 40% of our NGL production that is committed to
Phillips under an existing 15-year contract. We market approximately 370,000
barrels per day of NGLs processed at our owned and operated plants and 40,000
barrels per day of NGLs processed at third-party operated facilities and trade
approximately 75,000 barrels per day of NGLs at market centers.

     The residue gas that results from our processing is sold at market-based
prices to marketers or end-users, including large industrial customers and
natural gas and electric utilities serving individual consumers. We market
residue gas through our wholly owned gas marketing company. We also store
residue gas at our 8.5 billion cubic foot natural gas storage facility.

     On March 31, 2000, we obtained by transfer from Duke Energy the general
partner of TEPPCO. The general partner is responsible for the management and
operations of TEPPCO. We believe that our ownership of the general partner of
TEPPCO improves our business position in the transportation sector of the
midstream natural gas industry and provides additional flexibility in pursuing
our disciplined acquisition
                                       41
<PAGE>   43

strategy by providing an alternative acquisition vehicle. It also provides us
with an opportunity to sell appropriate assets currently held by our company to
TEPPCO. Through our ownership of the general partner of TEPPCO we have the right
to receive from TEPPCO incentive cash distributions in addition to a 2% share of
distributions based on our general partner interest. At TEPPCO's 1999 per unit
distribution level, the general partner:

          - receives approximately 14% of the cash distributed by TEPPCO to its
            partners, which consists of 12% from the incentive cash distribution
            and 2% from the general partner interest; and

          - under the incentive cash distribution provisions, receives 50% of
            any increase in TEPPCO's per unit cash distributions.

     TEPPCO has agreed to acquire Atlantic Richfield Company's 50% ownership
interest in Seaway Pipeline Company for $355 million. Seaway Pipeline Company
owns a 500-mile crude oil pipeline that extends from a marine terminal at
Freeport, Texas to Cushing, Oklahoma having a capacity of 350,000 barrels per
day, a 550-mile refined products pipeline that extends from Pasadena, Texas to
Cushing having a capacity of 85,000 barrels per day and a crude oil terminal
facility in the Houston area. TEPPCO will assume ARCO's role as operator of
Seaway. The transaction is contingent upon satisfaction of regulatory
requirements.

INDUSTRY OVERVIEW

     The midstream natural gas industry in North America is comprised of
approximately 150 companies that process approximately 45 billion cubic feet per
day of raw natural gas and produce approximately 1.9 million barrels per day of
NGLs. The industry generally is characterized by regional competition based on
the proximity of gathering systems and processing plants to natural gas
producing wells.

     Demand for natural gas in North America has grown significantly in recent
years. We believe that demand will continue to increase and will be driven
primarily by the growth of natural gas-fired electric generation. According to
the EIA Report, U.S. demand for natural gas is expected to increase from 22
trillion cubic feet in 1999 to 32 trillion cubic feet in 2020. We believe that
oil and natural gas producers in North America will respond to increased demand
by focusing their exploration and drilling efforts on basins where pipeline and
processing capacity has been, or is being, built and where there is sufficient
capacity to meet the needs of high demand markets. We have a strong presence and
significant capacity in several of these areas (including Onshore Gulf of Mexico
and Rocky Mountains, where we are among the three largest midstream natural gas
companies based on volumes of natural gas gathered and processed) that,
according to the EIA Report, are forecasted to have significant growth in
production between now and 2020. This growth in production, which is expected to
be 2.31 trillion cubic feet in Rocky Mountain region and 1.71 trillion cubic
feet in Onshore Gulf of Mexico region by 2020, should provide us with
opportunities to increase our throughput volumes and asset utilization.

     The midstream natural gas industry has experienced significant
consolidation since the mid-1990s. We believe the following factors have
contributed to this consolidation:

     - significant economies of scale resulting from improved operating
       efficiencies, throughput volumes and asset utilization rates that can be
       achieved by strategically growing operations;

     - decisions by transmission pipelines and by exploration and production
       companies to divest their gathering, processing and marketing activities
       and concentrate their businesses on gas transmission and on exploration
       and production; and

     - technological improvements.

OUR BUSINESS STRATEGY

     We are the largest gatherer of raw natural gas and the largest producer and
one of the largest marketers of NGLs in North America. Our certificate of
incorporation limits the scope of our business to the midstream natural gas

Directors and Duke Energy (so long as it owns at least a majority of our
outstanding common stock). We have significant midstream natural gas operations
in five of the largest natural gas producing regions in North America. To take
advantage of the anticipated growth in natural gas demand in North America, we
are pursuing the following strategies:


     - Capitalize on the size and focus of our existing operations. We intend to
       use the size, scope and concentration of our assets in our regions of
       operation to take advantage of growth opportunities and to acquire
       additional supplies of raw natural gas. Our significant market presence
       and asset base generally provide us with a competitive advantage in
       capturing new supplies of raw natural gas because of our resulting lower
       costs of connection to new wells and of processing additional raw natural
       gas. In addition, we believe our size and geographic diversity allow us
       to benefit from the growth of natural gas production in multiple regions
       while mitigating the adverse effects from a downturn in any one region.

     - Increase our presence in each aspect of the midstream business. We are
       active in each significant aspect of the midstream natural gas value
       chain, including raw natural gas gathering, processing, and
       transportation, NGL fractionation and NGL and residue gas transportation
       and marketing. Each link in the value chain provides us with an
       opportunity to earn incremental income from the raw natural gas that we
       gather and from the NGLs and residue gas that we produce. We intend to
       grow our significant NGL market presence by investing in additional NGL
       infrastructure, including pipelines, fractionators and terminals.

     - Increase our presence in high growth production areas.  According to the
       EIA Report, production from areas such as Western Canada, Onshore Gulf of
       Mexico, Rocky Mountains and Offshore Gulf of Mexico is expected to
       increase significantly to meet anticipated increases in demand for
       natural gas in North America. We intend to use our strategic asset base
       in these growth areas and our leading position in the midstream natural
       gas industry as a platform for future growth in these areas. We plan to
       increase our operations in these areas by following a disciplined
       acquisition strategy, and by expanding existing infrastructure and
       constructing new gathering lines and processing facilities.

     - Capitalize on proven acquisition skills in a consolidating industry. In
       addition to pursuing internal growth by attracting new raw natural gas
       supplies, we intend to use our substantial acquisition and integration
       skills to continue to participate selectively in the consolidation of the
       midstream natural gas industry. We have pursued a disciplined acquisition
       strategy focused on acquiring complementary assets during periods of
       relatively low commodity prices and integrating the acquired assets into
       our operations. Since 1996, we have completed over 20 acquisitions,
       increasing our raw natural gas processing capacity by over 275%. These
       acquisitions demonstrate our ability to successfully identify, acquire
       and integrate attractive midstream natural gas operations.

     - Further streamline our low-cost structure. Our economies of scale,
       operating efficiency and resulting low cost structure enhance our ability
       to attract new raw natural gas supplies and generate current income. The
       low-cost provider in any region can more readily attract new raw natural
       gas volumes by offering more competitive terms to producers. We believe
       the Combination provides us with a complementary base of assets from
       which to further extract operating efficiencies and cost reductions,
       while continuing to provide superior customer service.

NATURAL GAS GATHERING, PROCESSING, TRANSPORTATION, MARKETING AND STORAGE

     OVERVIEW

     Our raw natural gas gathering and processing operations consist of:

     - approximately 57,000 miles of gathering pipe, with connections to
       approximately 38,000 active producing wells; and

     - 70 owned and operated processing plants and ownership interests in 13
       additional third-party operated plants, with a combined processing
       capacity of approximately 7.9 billion cubic feet per day.

                                       43
<PAGE>   45


     In 1999, we gathered, processed and/or transported approximately 7.3
billion cubic feet per day of raw natural gas. During 1999, our natural gas
gathering, processing, transportation, marketing and storage activities produced
$981.5 million of gross margin and $583.1 million of EBITDA, excluding general
and administrative expenses.


     Our raw natural gas gathering and processing operations are located in 11
contiguous states in the United States and two provinces in Western Canada. We
provide services in the following key North American natural gas and oil
producing regions; Permian Basin, Mid-Continent, East Texas-Austin Chalk-North
Louisiana, Onshore Gulf of Mexico, Rocky Mountains, Offshore Gulf of Mexico and
Western Canada. We have a significant presence in the first five of these
producing regions where we are among the three largest midstream natural gas
companies based on volumes of natural gas gathered and processed.

     Raw Natural Gas Supply Arrangements. Typically, we take ownership of raw
natural gas at the wellhead. Each producer generally dedicates to us the raw
natural gas produced from designated oil and natural gas leases for a specific
term. The term will typically extend for three to seven years. We currently have
more than 15,000 active contracts with over 5,000 producers. We obtain access to
raw natural gas and provide our midstream natural gas service principally under
three types of contracts: percentage-of-proceeds contracts, fee-based contracts
and keep-whole contracts. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations -- Overview -- Effects of Our Raw Natural
Gas Supply Arrangements" for a description of these types of contracts.

     Raw Natural Gas Gathering. As of December 31, 1999, we had approximately 17
trillion cubic feet of raw natural gas supplies attached to our systems. We
receive raw natural gas from a diverse group of producers under contracts with
varying durations to provide a stable supply of raw natural gas through our
processing plants. A significant portion of the raw natural gas that is
processed by us is produced by large producers, including ExxonMobil, Union
Pacific Resources, BP Amoco and Phillips, which together account for
approximately 20% of our processed raw natural gas.

     We continually seek new supplies of raw natural gas, both to offset natural
declines in production from connected wells and to increase throughput volume.
Historically, we have been successful in connecting additional supplies to more
than offset natural declines in production.

     We obtain new well connections in our operating areas by contracting for
production from new wells or by obtaining raw natural gas that has been released
from other gathering systems. Producers may switch raw natural gas from one
gathering system to another to obtain better commercial terms, conditions and
service levels.


     We believe our significant asset base and scope of our operations provides
us with significant opportunities to add released raw natural gas to our
systems. In addition, we have significant processing capacity in the Onshore
Gulf of Mexico, Offshore Gulf of Mexico and Rocky Mountain regions, which,
according to the Energy Information Administration's report "U.S. Crude Oil,
Natural Gas and Natural Gas Liquids Reserves, 1998 Annual Report," contain
significant quantities of proved natural gas reserves. We also have a presence
in other potential high-growth areas such as the Western Canadian Sedimentary
Basin. As a result of new connections resulting from both increased drilling and
released raw natural gas, we connected approximately 1,300 additional wells in
1998 and 1,500 additional wells in 1999.


     Gathering systems are operated at design pressures that will maximize the
total throughput from all connected wells. On gathering systems where it is
economically feasible, we operate at a relatively low pressure, which can allow
us to offer a significant benefit to raw natural gas producers. Specifically,
lower pressure gathering systems allow wells, which produce at progressively
lower field pressures as they age, to remain connected to gathering systems and
continue to produce for longer periods of time. As the pressure of a well
declines, it becomes increasingly more difficult to deliver the remaining
production in the ground against a higher pressure that exists in the connecting
gathering system. Field compression is typically used to lower the pressure of a
gathering system. If field compression is not installed, then the remaining
production in the ground will not be produced because it cannot overcome the
higher gathering system pressure. In contrast, if field compression is
installed, then a well can continue delivering production that otherwise would
not be

                                       44
<PAGE>   46

produced. Our field compression systems provide the flexibility of connecting a
high pressure well to the downstream side of the compressor even though the well
is producing at a pressure greater than the upstream side. As the well ages and
the pressure naturally declines, the well can be reconnected to the upstream,
low pressure side of the compressor and continue to produce. By maintaining low
pressure systems with field compression units, we believe that the wells
connected to our systems are able to produce longer and at higher volumes before
disconnection is required.

     Raw Natural Gas Processing. Most of our natural gas gathering systems feed
into our natural gas processing plants. Our processing plants produced an
average of approximately 4.7 billion cubic feet per day of residue gas and an
average of approximately 400,000 barrels per day of NGLs during 1999.

     Our natural gas processing operations involve the extraction of NGLs from
raw natural gas, and, at certain facilities, the fractionation of NGLs into
their individual components (ethane, propane, butanes and natural gasoline). We
sell NGLs produced by our processing operations to a variety of customers
ranging from large, multi-national petrochemical and refining companies,
including Phillips, to small, regional retail propane distributors.

     At three plants, we also extract helium from the residue gas stream. Helium
is used for medical diagnostics, in arc welding and other metallurgical and
chemical processes, in the space exploration program and other scientific
applications, for diluting oxygen for breathing (by patients with respiratory
ailments and by deep-sea divers) and for inflating lighter-than-air aircraft and
balloons. These plants are among the few helium extraction facilities in the
United States. We extracted approximately 1.3 billion cubic feet of helium
during 1999, producing revenues of approximately $33 million.

     Hydrogen sulfide also is separated in the treating and processing cycle.
During 1999, we produced and sold approximately 93,000 long tons of sulfur,
producing revenues of approximately $1.1 million.

     We also remove off-quality crude oil, nitrogen, carbon dioxide and brine
from the raw natural gas stream. The nitrogen and carbon dioxide are released
into the atmosphere, and the crude oil and brine are accumulated and stored
temporarily at field compressors or the various plants. The brine is transported
to licensed disposal wells owned either by us or by third parties. The crude oil
is sold in the off-quality crude oil market.

     Residue Gas Marketing. In addition to our gathering and processing
activities discussed above, we are involved in the purchase and sale of residue
gas, directly or through our wholly owned gas marketing company. Our gas
marketing efforts primarily involve supplying the residue gas demands of
end-user customers that are physically attached to our pipeline systems and
supplying the gas processing requirements associated with our keep-whole
processing agreements.

     We are focused on extracting the highest possible value for the residue gas
that results from our processing and transportation operations. Of the residue
gas that we market, we currently sell approximately 25% to various on-system
users and approximately 75% to industrial end-users, national wholesale gas
marketing companies (including Duke Energy Trading and Marketing, a subsidiary
of Duke Energy and one of the largest gas marketers in the United States) and
electric utilities.

     Our Spindletop storage facility plays an important role in our ability to
act as a full-service natural gas marketer. We lease approximately two-thirds of
the facility's capacity to our customers, and we use the balance to manage
relatively constant natural gas supply volumes with uneven demand levels and
provide "backup" service to our customers.

     The natural gas marketing industry is a highly competitive commodity
business with a significant degree of price transparency. We provide a full
range of natural gas marketing services in conjunction with the gathering,
processing, and transportation services we offer on our facilities, which allows
us to use our asset infrastructure to enhance our revenues across each aspect of
the natural gas value chain.

     Financial Services. We provide mezzanine financing to producers seeking
capital for production enhancement in our core physical and marketing asset
areas. We provide financing to operators as part of our efforts to increase
utilization of our existing assets, gain access to incremental supplies and
generate
                                       45
<PAGE>   47

opportunities for us to expand existing infrastructure and/or construct new
gathering lines and processing facilities. The majority of the financing plans
we offer are asset-based and we require that our producers satisfy risk/reward
tolerances. This program has created significant gathering and processing
opportunities for us. At December 31, 1999, we had $21.9 million in financing
outstanding under this program.

     REGIONS OF OPERATIONS

     Our operations cover substantially all of the major natural gas producing
regions in the United States, as well as portions of Western Canada. In
addition, our geographic diversity reduces the impact of regional price
fluctuations and regional changes in drilling activity.

     Our raw natural gas gathering and processing assets are managed in line
with the seven geographic regions in which we operate. The following table
provides information concerning the raw natural gas gathering systems and
processing plants currently owned or operated by us.

    on our behalf.

     Our key suppliers of raw natural gas in these seven regions include major
integrated oil companies, independent oil and gas producers, intrastate pipeline
companies and natural gas marketing companies. Our principal competitors in this
segment of our business consist of major integrated oil companies, independent
oil and gas gathers, and interstate and intrastate pipeline companies.

     Regional Growth Strategies. Growth of our gas gathering and processing
operations is key to our success. Increased raw natural gas supply enables us to
increase throughput volumes and asset utilization throughout our entire
midstream natural gas value chain. As we develop our regional growth strategies,
we evaluate the nature of the opportunity that a particular region presents. The
attributes that we evaluate include the nature of the gas reserves and
production profile, existing midstream infrastructure including capacity and
capabilities, the regulatory environment, the characteristics of the
competition, and the competitive position of our assets and capabilities. In a
general sense, we employ one or more of the strategies described below:

     - Growth -- in regions where production is expected to grow significantly
       and/or there is a need for additional gathering and processing
       infrastructure, we plan to expand our gathering and processing assets by
       following a disciplined acquisition strategy, by expanding existing
       infrastructure, and by constructing new gathering lines and processing
       facilities.

     - Consolidation -- in regions that include mature producing basins with
       flat to declining production or that have excess gathering and processing
       capacity, we seek opportunities to efficiently consolidate the existing
       asset base in order to increase utilization and operating efficiencies
       and realize economies of scale.

     - Opportunistic -- in regions where production growth is not primarily
       generated by new exploration drilling activity we intend to optimize our
       existing assets and selectively expand certain facilities or

                                       46
<PAGE>   48

       construct new facilities to seize opportunities to increase our
       throughput. These regions are generally experiencing stable to increasing
       production through the application of new drilling technologies like 3-D
       seismic, horizontal drilling and improved well completion techniques. The
       application of new technologies is causing the drilling of additional
       wells in areas of existing production and recompletions of existing wells
       which create additional opportunities to add new gas supplies.

     In each region, we plan to apply both our broad overall business strategy
and the strategy uniquely suited to each region. We believe this plan will yield
balanced growth initiatives, including new construction in certain high growth
areas, expansion of existing systems and complementary acquisitions, combined
with efficiency improvements and/or asset consolidation. We also plan to
rationalize assets and redeploy capital to higher value opportunities.

     A description of our operations, key suppliers and principal competitors in
each region is set forth below:


     Permian Basin. Our facilities in this region are located in West Texas and
Southeast New Mexico. We own majority interests in and are the operator of 19
natural gas processing plants in this region. In addition, we own minority
interests in two other natural gas processing plants that are operated by
others. Our natural gas processing plants are strategically located to access
production of the Permian Basin. Our plants have processing capacity net to our
interest of 1.4 billion cubic feet of raw natural gas per day. Operations in
this region are primarily focused on gathering and processing, but we also are
positioned for marketing residue gas and NGLs. We offer low, intermediate, and
high pressure gathering and processing and both high and low NGLs content
treating. Three of our processing facilities provide fractionation services.
Residue gas sales are enhanced by access to the Waha Hub where multiple pipeline
interconnects source gas for virtually every market in the United States. Our
older facilities have been modernized to improve product recoveries, and most of
our plants offer sulfur removal. During 1999, these plants operated at an
overall 79% capacity utilization rate. On average, the raw natural gas from West
Texas contains approximately 5.2 gallons of NGLs per thousand cubic feet, while
raw natural gas from New Mexico contains approximately 4.6 gallons of NGLs per
thousand cubic feet.


     As we generally pursue a consolidation strategy in this region, our assets
will allow us to compete for new gas supplies in most major fields and benefit
from the expected increase in drilling and production from technological
advances. In addition, our ability to redirect gas between several processing
plants allows us to maximize utilization of our processing capacity in this
region.

     Our key suppliers in this region include ExxonMobil, Union Pacific
Resources and Yates Petroleum. Our principal competitors in this region include
Dynegy, Koch and Texaco.


     Mid-Continent. Our facilities in this region are located in Oklahoma,
Kansas and the Texas Panhandle. In this region, we own and are the operator of
19 natural gas processing plants, 18 in which we own a 100% interest and one in
which we own a 50% interest. We also own minority interests in two other natural
gas processing plants that are operated by others. We gather and process raw
natural gas primarily from the Arkoma, Ardmore, and Anadarko basins, including
the prolific Hugoton and Panhandle fields. Our plants have processing capacity
net to our interest of 2.3 billion cubic feet of raw natural gas per day. During
1999, our plants operated at an overall 65% capacity utilization rate. On
average, the raw natural gas from this region contains from 3 to 5 gallons of
NGLs per thousand cubic feet.


     We also produce approximately 28% of the United States domestic supply of
helium from our Mid-Continent facilities. Annual growth in demand for helium
over the past 15 years has been approximately 8.5% per year. Because of its
unique characteristics and use as an industrial gas, we expect demand for helium
to grow well into the future.

     Existing production in the Mid-Continent region is typically from mature
fields with shallow decline profiles that will provide our plants with a
dependable source of raw natural gas over a long term. With the development of
improved exploration and production techniques such as 3-D seismic and
horizontal drilling over the past several years, additional reserves have become
economically producible in this region. We hold large acreage dedication
positions with various producers who have developed programs to add
substantially to

                                       47
<PAGE>   49

their reserve base. The infrastructure of our plants and gathering facilities
are uniquely positioned to pursue our consolidation strategy.

     Our key suppliers in this region include Phillips, OXY USA and Anadarko
Petroleum. Our principal competitors in this region include Coastal Field
Services, Oneok Field Services and Enogex Inc.

     East Texas-Austin Chalk-North Louisiana. Our facilities in this region are
located in East Texas, North Louisiana and the Austin Chalk formation of East
Central Texas and Central Louisiana. We own majority interests in and are the
operator of 10 natural gas processing plants in this region. In addition, we own
a minority interest in one natural gas processing plant that is operated by
another entity. Our plants have processing capacity net to our interest of 1.6
billion cubic feet of raw natural gas per day. During 1999, these plants
operated at an overall 66% capacity utilization rate. In this region we also own
three intrastate gathering systems, which, in the aggregate, can gather and
transport approximately 480 million cubic feet of raw natural gas per day.

     Our East Texas operations are centered around our East Texas Complex,
located near Carthage, Texas. This plant complex is the second largest raw
natural gas processing facility in the continental United States, based on
liquids recovery, and currently produces approximately 40,000 barrels per day of
NGLs. Our 165-mile gathering network aggregates production to the East Texas
Complex, which currently gathers approximately 130 million cubic feet of raw
natural gas per day. In addition, the plant is connected to and processes raw
natural gas from several other gathering systems, including those owned by Koch,
Union Pacific Resources and American Central. Substantially all of the raw
natural gas processed at the complex is contracted under percent-of-proceeds
agreements with an average remaining term of approximately six years. This plant
is adjacent to our Carthage Hub, which delivers residue gas to interconnects
with 14 interstate and intrastate pipelines. The Carthage Hub, with an aggregate
delivery capacity of two billion cubic feet per day, acts as a key exchange
point for the purchase and sale of residue gas. We also operate Panola pipeline,
with throughput capacity of up to 40,000 barrels per day, which carries NGLs
from our East Texas Complex to markets in Mont Belvieu, Texas. In this region,
we also own and operate the Fuels Cotton Valley Gathering System, which consists
of 76 miles of pipeline and which gathers approximately 30 million cubic feet of
raw natural gas per day.

     As we pursue a combination of opportunistic and consolidation strategies in
this diverse region, we intend to leverage our modern processing capacity,
intrastate gas pipeline and NGL assets.

     Our key suppliers in this region include Union Pacific Resources, Devon and
Phillips. Our principal competitors in this region include Koch, El Paso Field
Services and Southwest Pipeline Corporation.

     Onshore Gulf of Mexico. Our facilities in this region are located in South
Texas and the Southeastern portions of the Texas Gulf Coast. We own a 100%
interest in and are the operator of seven natural gas processing plants and the
Spindletop gas storage facility in this region. In addition, we own a minority
interest in one natural gas processing plant that is operated by another entity.
Our plants have processing capacity net to our interest of 1.1 billion cubic
feet of raw natural gas per day. During 1999, the plants in this region ran at
an overall 70% capacity utilization rate.

     Our Spindletop natural gas storage facility is located near Beaumont, Texas
and has current working natural gas capacity of 8.5 billion cubic feet, plus
expansion potential of up to an additional 10 billion cubic feet. We currently
have approximately 5.6 billion cubic feet of the available storage capacity
under lease with expiration terms out to July 2004. This high deliverability
storage facility is positioned to meet the needs of the natural gas-fired
electric generation marketplace, currently the fastest growing demand segment of
the natural gas industry. The facility interconnects with 12 interstate and
intrastate pipelines and is designed to handle the hourly demand needs of power
generators.

     To achieve growth in our Onshore Gulf of Mexico region, we intend to fully
integrate our recently acquired assets and use the diversity of our current
asset base to provide value-added services to our broad customer base. We will
also seek additional opportunities to participate in the anticipated growth in
supply from this region.

                                       48

     Our key suppliers in this region include Collins & Ware, United Oil and
Minerals and TransTexas. Our principal competitors in this region include PG&E
Texas Transmission, Tejas Gas Corp. and Houston Pipe Line Company.

     Rocky Mountains. Our facilities in this region are located in the DJ Basin
of Northern Colorado, the Ladder Creek area of Southeast Colorado and the
Greater Green River Basin and Overthrust Belt areas of Southwest Wyoming and
Northeast Utah. We own a 100% interest in and are the operator of 10 natural gas
processing plants in this region. In addition, we own a minority interest in one
natural gas processing plant that is operated by another entity. Our plants have
processing capacity net to our interest of 600 million cubic feet of raw natural
gas per day. During 1999, our plants in this region operated at an overall 65%
capacity utilization rate. These assets provide for the gathering and processing
of raw natural gas, the transportation and fractionation of NGLs, nitrogen
rejection, and helium extraction and liquification services.

     The Rocky Mountains region has well placed assets with strong competitive
positions in areas that are expected to benefit from increased drilling
activity, providing us with a platform for growth. In this region, we expect to
achieve growth through our existing assets, strategic acquisitions and
development of new facilities. In addition, we intend to pursue an opportunistic
strategy in areas where new technologies and recovery methods are being
employed.

     Our key suppliers in the region include Patina Oil & Gas, HS Resources and
Union Pacific Resources. Our principal competitors in this region include HS
Resources, Williams Field Services and Western Gas Resources.

     Offshore Gulf of Mexico. Our facilities in this region are located along
the Gulf Coast areas of Louisiana, Mississippi and Alabama. We own minority
interests in and are the operator of two natural gas processing plants in this
region. In addition, we own a 50% interest in one natural gas processing plant
and minority interests in five other natural gas processing plants, all of which
are operated by other entities. The plants have processing capacity net to our
interest of 909 million cubic feet of raw natural gas per day. During 1999, our
plants in this region operated at an overall 81% capacity utilization rate. Each
of these plants straddle offshore pipeline systems delivering a relatively lower
NGLs content gas stream than that of our onshore gathering systems, as
approximately 50% of the produced NGLs content consists of ethane. As a result,
the offshore region's revenues are concentrated in fee-based business
arrangements and are less dependent on fluctuating commodity prices.

     In addition, we own a 37% interest in the Dauphin Island Gathering
Partnership, an offshore gathering and transmission system. Dauphin Island has
attractive market outlets, including deliveries to Texas Eastern Transmission
Corporation, Transco, Koch, Gateway and Florida Gas Transmission for re-delivery
to the Southeast, Mid-Atlantic, Northeast and New England natural gas markets.
Dauphin Island's leased capacity on Texas Eastern Transmission Corporation's
pipeline provides us with a means to cross the Mississippi River to deliver or
receive production from the Venice, Louisiana natural gas hub area. Further, the
Main Pass Oil Gathering Company system, in which we own a 33% interest, also has
access to a variety of markets through existing shallow-water and deep-water
interconnections and dual market outlets into Shell's Delta terminal as well as
Chevron's Cypress terminal.

     We believe that the Offshore Gulf of Mexico production area will be one of
the most active regions for new drilling in the United States. Our strategic
growth plan for this region is to add new facilities to our existing base so
that we can capture new offshore development opportunities. Our existing assets
in the eastern Gulf of Mexico are positioned to access new and ongoing
production developments. Based on our broad range of assets in the region, we
intend to capture incremental margins along the natural gas value chain.

     Our key suppliers in the Offshore Gulf of Mexico region include Coastal,
ExxonMobil and CNG Producing Company. Our principal competitors in this region
include El Paso Energy, Coral Energy and Williams.

     Western Canada. We own a majority interest in and are the operator of three
natural gas processing plants in Western Canada that are strategically located
in the Peace River Arch area of Northwestern Alberta. Our facilities in this
region have processing capacity net to our interest of 109 million cubic feet of
raw natural
                                       49
<PAGE>   51

gas per day. Our 144-mile gathering system located in this region supports these
processing facilities. During 1999, our processing plants in this area operated
at an overall 70% capacity utilization rate. Our processing facilities in this
area are new, with the majority having been constructed since 1995. Our
processing arrangements are primarily fee-based, providing an income stream that
is not subject to fluctuations in commodity prices.

     The Peace River Arch area continues to be an active drilling area with land
widely held among several large and small producers. Multiple residue gas market
outlets can be accessed from our facilities through connections to TransCanada's
NOVA system, the Westcoast system into British Columbia and the Alliance
Pipeline, scheduled to be operational in October 2000.

     According to the EIA Report, less than 20% of the gathering and processing
assets in the area are owned by midstream gathering and processing companies. As
a result, we believe that significant growth opportunities exist in this region.
We anticipate that producers in this area may follow the lead of U.S. producers
and divest their midstream assets over the next few years. We are positioned to
capitalize on this fundamental shift in the Canadian natural gas processing
industry and plan to expand our position in Alberta and British Columbia through
additional acquisitions and greenfield projects.

     Our key suppliers in this region include Star Oil & Gas Ltd., Talisman
Energy Inc. and Anderson Exploration Ltd. Our principal competitors in the area
include TransCanada Midstream, Talisman Energy Inc. and Westcoast Energy, Inc.

NATURAL GAS LIQUIDS TRANSPORTATION, FRACTIONATION AND MARKETING

     OVERVIEW


     We market our NGLs and provide marketing services to third party NGL
producers and sales customers in significant NGL production and market centers
in the United States. During 1999, our NGL transportation, fractionation and
marketing activities produced $38.3 million of gross margin and $38.1 million of
EBITDA, excluding general and administrative expenses. In 1999, we marketed and
traded approximately 486,000 barrels of NGLs per day, of which approximately 85%
was production for our own account, ranking us as one of the largest NGLs
marketers in the country.


     Our NGL services include plant tailgate purchases, transportation,
fractionation, flexible pricing options, price risk management and
product-in-kind agreements. Our primary NGL operations are located in close
proximity to our gathering and processing assets in each of the regions in which
we operate, other than Western Canada. We own interests in two NGLs
fractionators at the Mont Belvieu, Texas market center, the Mont Belvieu I
fractionation facility and the Enterprise Products fractionation facility. In
addition, we own interests in two major NGLs pipelines serving the Mont Belvieu
facilities, the wholly owned Panola Pipeline in East Texas and an interest in
the Black Lake Pipeline in Louisiana and East Texas. We also own several
regional fractionation plants and NGLs pipelines.


     We possess a large asset base of NGL fractionators and pipelines that are
used to provide value-added services to our refining, chemical, industrial,
retail and wholesale propane-marketing customers. We intend to capture premium
value in local markets while maintaining a low cost structure by maximizing
facility utilization at our 12 regional fractionators and 12 pipeline systems.
Our current fractionation capacity is approximately 152,000 barrels per day.


     STRATEGY

     Our strategy is to exploit the size, scope and reliability of supply from
our raw natural gas processing operations and apply our knowledge of NGL market
dynamics to make additional investments in NGL infrastructure. Our
interconnected natural gas processing operations provide us with an opportunity
to capture fee-based investment opportunities in certain NGL assets, including
pipelines, fractionators and terminals. In conjunction with this investment
strategy and as an enhancement to the margin generation from our NGL assets, we
also intend to focus on the following areas: producer services, local sales and
fractionation, market

                                       50
<PAGE>   52

hub fractionation, transportation and market center trading and storage, each of
which briefly is discussed below.

     Producer Services. We plan to expand our services to producers principally
in the areas of price risk management and handling the marketing of their
products. Over the last several years, we have expanded our supply base
significantly beyond our own equity production by providing a long-term market
for third-party NGLs at competitive prices.

     Local Sales and Fractionation. We will seek opportunities to maximize value
of our product by expanding local sales. We have fractionation capabilities at
14 of our raw natural gas processing plants. Our ability to fractionate NGLs at
regional processing plants provides us with direct access to local NGLs markets.

     Market Hub Fractionation. We will focus on optimizing our product slate
from our two Gulf Coast fractionators, the Mont Belvieu I and Enterprise
Products fractionators, where we have a combined owned capacity of 57,000
barrels per day. The control of products from these fractionators complements
our market center trading activity.

     Transportation. We will seek additional opportunities to invest in NGL
pipelines and secure favorable third party transportation arrangements. We use
company-owned NGL pipelines to transport approximately 94,500 barrels per day of
our total NGL pipeline volumes, providing transportation to market center
fractionation hubs or to end use markets. We also are a significant shipper on
third party pipelines in the Rocky Mountains, Mid-Continent and Permian Basin
producing regions and, as a result, receive the benefit of incentive rates on
many of our NGLs shipments.

     Market Center Trading and Storage. We use trading and storage at the Mont
Belvieu, Texas and Conway, Kansas NGL market centers to manage our price risk
and provide additional services to our customers. We undertake these activities
through the use of fixed forward sales, basis and spread trades, storage
opportunities, put/call options, term contracts and spot market trading. We
believe there are additional opportunities to grow our price risk management
services with our industrial customer base.

     KEY SUPPLIERS AND COMPETITION

     The marketing of NGLs is a highly competitive business that involves
integrated oil and natural gas companies, mid-stream gathering and processing
companies, trading houses, international liquid propane gas producers and
refining and chemical companies. There is competition to source NGLs from plant
operators for movement through pipeline networks and fractionation facilities as
well as to supply large consumers such as multi-state propane, refining and
chemical companies with their NGLs needs. Our three largest suppliers are our
own plants, Union Pacific Resources and Pacific Gas & Electric. Our largest
sales customers are Phillips, Dow Chemical and ExxonMobil, which accounted for
12%, 2% and 1%, respectively, of our total revenues in 1999. Our three principal
competitors in the marketing of NGLs are Dynegy, Koch and Enterprise. In 1999,
we marketed and traded an average of approximately 486,000 barrels per day, or
approximately 19% of the available domestic supply, which includes gas plant
production, refinery plant production and imports.


TEPPCO


     On March 31, 2000, we obtained by transfer from Duke Energy, the general
partner of TEPPCO, a publicly traded master limited partnership. TEPPCO operates
in two principal areas:

     - refined products and liquefied petroleum gases transportation; and

     - crude oil and NGLs transportation and marketing.

     TEPPCO is one of the largest pipeline common carriers of refined petroleum
products and liquefied petroleum gases in the United States. Its operations in
this line of business consist of:

     - interstate transportation, storage and terminaling of petroleum products;

                                       51
<PAGE>   53

     - short-haul shuttle transportation of liquefied petroleum gas at the Mont
       Belvieu, Texas complex;

     - sale of product inventory;

     - fractionation of NGLs; and

     - ancillary services.

TEPPCO's refined products and liquefied petroleum gas pipeline system includes
approximately 4,300 miles of pipeline which extend from southeast Texas through
the central and midwestern United States to the northeastern United States.
TEPPCO's refined products and liquefied petroleum gas pipeline system has
storage capacity of 13 million barrels of refined petroleum products and 38
million barrels of liquefied petroleum gas.

     Through its crude oil and NGLs transportation and marketing business,
TEPPCO gathers, stores, transports and markets crude oil, NGLs, lube oil and
specialty chemicals, principally in Oklahoma, Texas and the Rocky Mountain
region. TEPPCO's crude oil and NGLs assets include approximately 1,950 miles of
crude oil pipeline and 1.7 million barrels of crude oil storage and
approximately 425 miles of NGL pipeline with an aggregate capacity of 25,000
barrels per day.

     We believe that our ownership of the general partnership interest of TEPPCO
improves our business position in the transportation sector of the midstream
natural gas industry and provides us additional flexibility in pursuing our
disciplined acquisition strategy by providing an alternative acquisition
vehicle. It also provides us with an opportunity to sell appropriate assets
currently held by our company to TEPPCO.

     The general partner of TEPPCO manages and directs TEPPCO under the TEPPCO
partnership agreement and the partnership agreements of its operating
partnerships. Under the partnership agreements, the general partner of TEPPCO is
reimbursed for all direct and indirect expenses it incurs or payments it makes
on behalf of TEPPCO.

     TEPPCO makes quarterly cash distributions of its available cash, which
consists generally of all cash receipts less disbursements and cash reserves
necessary for working capital, anticipated capital expenditures and
contingencies, the amounts of which are determined by the general partner of
TEPPCO.

     The partnership agreements provide for incentive distributions payable to
the general partner of TEPPCO out of TEPPCO's available cash in the event
quarterly distributions to its unitholders exceed certain specified targets. In
general, subject to certain limitations, if a quarterly distribution exceeds a
target of $.275 per limited partner unit, the general partner of TEPPCO will
receive incentive distributions equal to:

     - 15% of that portion of the distribution per limited partner unit which
       exceeds the minimum quarterly distribution amount of $.275 but is not
       more than $.325, plus

     - 25% of that portion of the quarterly distribution per limited partner
       unit which exceeds $.325 but is not more than $.45, plus

     - 50% of that portion of the quarterly distribution per limited partner
       unit which exceeds $.45.

     At TEPPCO's 1999 per unit distribution level, the general partner:

     - receives approximately 14% of the cash distributed by TEPPCO to its
       partners, which consists of 12% from the incentive cash distribution and
       2% from the general partner interest; and

     - under the incentive cash distribution provisions, receives 50% of any
       increase in TEPPCO's per unit cash distributions.

     During 1999, total cash distributions to the general partner of TEPPCO were
$8.3 million.

     TEPPCO has agreed to acquire Atlantic Richfield Company's 50% ownership
interest in Seaway Pipeline Company for $355 million. Seaway Pipeline Company
owns a 500-mile crude oil pipeline that extends from a marine terminal at
Freeport, Texas to Cushing, Oklahoma having a capacity of 350,000 barrels per
day, a 550-

                                       52
<PAGE>   54

mile refined products pipeline that extends from Pasadena, Texas to Cushing
having a capacity of 85,000 barrels per day and a crude oil terminal facility in
the Houston area. TEPPCO will assume ARCO's role as operator of Seaway. The
transaction is contingent upon satisfaction of regulatory requirements.

NATURAL GAS SUPPLIERS


     We purchase substantially all of our raw natural gas from producers under
varying term contracts. Typically, we take ownership of raw natural gas at the
wellhead, settling payments with producers on terms set forth in the applicable
contracts. These producers range in size from small independent owners and
operators to large integrated oil companies, such as Phillips, our largest
single supplier. No single producer accounted for more than 10% of our natural
gas throughput in 1999. Each producer generally dedicates to us the raw natural
gas produced from designated oil and natural gas leases for a specific term. The
term will typically extend for three to seven years and in some cases for the
life of the lease. We currently have over 15,000 active contracts with over
5,000 producers. We consider our relations with our producers to be good. For a
description of the types of contracts we have entered into with our suppliers,
see "Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Overview -- Effects of Our Raw Natural Gas Supply Arrangements."


COMPETITION

     We face strong competition in acquiring raw natural gas supplies. Our
competitors in obtaining additional gas supplies and in gathering and processing
raw natural gas include:

     - major integrated oil companies;

     - major interstate and intrastate pipelines or their affiliates;

     - other large raw natural gas gatherers that gather, process and market
       natural gas and/or NGLs; and

     - a relatively large number of smaller raw natural gas gatherers of varying
       financial resources and experience.

     Competition for raw natural gas supplies is concentrated in geographic
regions based upon the location of gathering systems and natural gas processing
plants. Although we are one of the largest gatherers and processors in most of
the geographic regions in which we operate, most producers in these areas have
alternate gathering and processing facilities available to them. In addition,
producers have other alternatives, such as building their own gathering
facilities or in some cases selling their raw natural gas supplies without
processing. Competition for raw natural gas supplies in these regions is
primarily based on:

     - the reputation, efficiency and reliability of the gatherer/processor,
       including the operating pressure of the gathering system;

     - the availability of gathering and transportation;

     - the pricing arrangement offered by the gatherer/processor; and

     - the ability of the gatherer/processor to obtain a satisfactory price for
       the producers' residue gas and extracted NGLs.

     In addition to competition in raw natural gas gathering and processing,
there is vigorous competition in the marketing of residue gas. Competition for
customers is based primarily upon the price of the delivered gas, the services
offered by the seller, and the reliability of the seller in making deliveries.
Residue gas also competes on a price basis with alternative fuels such as oil
and coal, especially for customers that have the capability of using these
alternative fuels and on the basis of local environmental considerations. Also,
to foster competition in the natural gas industry, certain regulatory actions of
FERC and some states have allowed buying and selling to occur at more points
along transmission and distribution systems.

                                       53
<PAGE>   55

     Competition in the NGLs marketing area comes from other midstream NGLs
marketing companies, international producers/traders, chemical companies and
other asset owners. Along with numerous marketing competitors, we offer price
risk management and other services. We believe it is important that we tailor
our services to the end-use customer to remain competitive.

REGULATION

     Transportation. Historically, the transportation and sale for resale of
natural gas in interstate commerce have been regulated under the Natural Gas Act
of 1938, the Natural Gas Policy Act of 1978, and the regulations promulgated
thereunder by FERC. In the past, the federal government regulated the prices at
which natural gas could be sold. In 1989, Congress enacted the Natural Gas
Wellhead Decontrol Act, which removed all Natural Gas Act and Natural Gas Policy
Act price and non-price controls affecting wellhead sales of natural gas.
Congress could, however, reenact field natural gas price controls in the future,
though we know of no current initiative to do so.

     As a gatherer, processor and marketer of raw natural gas, we depend on the
natural gas transportation and storage services offered by various interstate
and intrastate pipeline companies to enable the delivery and sale of our residue
gas supplies. In accordance with methods required by FERC for allocating the
system capacity of "open access" interstate pipelines, at times other system
users can preempt the availability of interstate natural gas transportation and
storage service necessary to enable us to make deliveries and sales of residue
gas. Moreover, shippers and pipelines may negotiate the rates charged by
pipelines for such services within certain allowed parameters. These rates will
also periodically vary depending upon individual system usage and other factors.
An inability to obtain transportation and storage services at competitive rates
can hinder our processing and marketing operations and affect our sales margins.

     The intrastate pipelines that we own are subject to state regulation and,
to the extent they provide interstate services under Section 311 of the Natural
Gas Policy Act of 1978, also are subject to FERC regulation. We also own an
interest in a natural gas gathering system and interstate transmission system
located in offshore waters south of Louisiana and Alabama. The offshore
gathering system is not a jurisdictional entity under the Natural Gas Act; the
interstate offshore transmission system is regulated by FERC.

     Commencing in April 1992, FERC issued Order No. 636 and a series of related
orders that require interstate pipelines to provide open-access transportation
on a basis that is equal for all marketers of natural gas. FERC has stated that
it intends for Order No. 636 to foster increased competition within all phases
of the natural gas industry. Order No. 636 applies to our activities in Dauphin
Island Gathering Partners and how we conduct gathering, processing and marketing
activities in the market place serviced by Dauphin Island Gathering Partners.
The courts have largely affirmed the significant features of Order No. 636 and
the numerous related orders pertaining to individual pipelines, although certain
appeals remain pending and FERC continues to review and modify its regulations.
For example, the FERC recently issued Order No. 637 which, among other things:

     - lifts the cost-based cap on pipeline transportation rates in the capacity
       release market until September 30, 2002 for short-term releases of
       pipeline capacity of less than one year;

     - permits pipelines to charge different maximum cost-based rates for peak
       and off-peak periods;

     - encourages, but does not mandate, auctions for pipeline capacity;

     - requires pipelines to implement imbalance management services;

     - restricts the ability of pipelines to impose penalties for imbalances,
       overruns and non-compliance with operational flow orders; and

     - implements a number of new pipeline reporting requirements.

Order No. 637 also requires the FERC to analyze whether the FERC should
implement additional fundamental policy changes, including, among other things,
whether to pursue performance-based ratemaking
                                       54
<PAGE>   56

or other non-cost based ratemaking techniques and whether the FERC should
mandate greater standardization in terms and conditions of service across the
interstate pipeline grid. In addition, the FERC recently implemented new
regulations governing the procedure for obtaining authorization to construct new
pipeline facilities and has issued a policy statement, which it largely affirmed
in a recent order on rehearing, establishing a presumption in favor of requiring
owners of new pipeline facilities to charge rates based solely on the costs
associated with such new pipeline facilities. We cannot predict what further
action FERC will take on these matters. However, we do not believe that we will
be affected by any action taken previously or in the future on these matters
materially differently than other natural gas gatherers, processors and
marketers with which we compete.

     Additional proposals and proceedings that might affect the natural gas
industry are pending before Congress, FERC and the courts. The natural gas
industry historically has been heavily regulated; therefore, there is no
assurance that the less stringent and pro-competition regulatory approach
recently pursued by FERC and Congress will continue.

     Gathering. The Natural Gas Act exempts natural gas gathering facilities
from the jurisdiction of FERC. Interstate natural gas transmission facilities,
on the other hand, remain subject to FERC jurisdiction. FERC has historically
distinguished between these two types of facilities on a fact-specific basis. We
believe that our gathering facilities and operations meet the current tests that
FERC uses to grant non-jurisdictional gathering facility status. However, there
is no assurance that FERC will not modify such tests or that all of our
facilities will remain classified as natural gas gathering facilities.

     Some states in which we own gathering facilities have adopted laws and
regulations that require gatherers either to purchase without undue
discrimination as to source or supplier or to take ratably without undue
discrimination natural gas production that may be tendered to the gatherer for
handling. For example, the states of Oklahoma and Kansas also have adopted
complaint-based statutes that allow the Oklahoma Corporation Commission and the
Kansas Corporation Commission, respectively, to remedy discriminatory rates for
providing gathering service where the parties are unable to agree. In a similar
way, the Railroad Commission of Texas sponsors a complaint procedure for
resolving grievances about natural gas gathering access and rate discrimination.

     The FERC recently issued Order No. 639, requiring that virtually all
non-proprietary pipeline transporters of natural gas on the outer-continental
shelf report information on their affiliations, rates and conditions of service.
Among FERC's purposes in issuing these rules was the desire to provide shippers
on the outer-continental shelf with greater assurance of open-access services on
pipelines located on the outer-continental shelf and non-discriminatory rates
and conditions of service on these pipelines. The FERC exempted Natural Gas
Act-regulated pipelines, like Dauphin Island Gathering Partners, from the new
reporting requirements, reasoning that the information that these pipelines were
already reporting was sufficient to monitor conformity with existing
non-discrimination mandates. However, pipelines not regulated under the Natural
Gas Act, like our gathering lines located on the outer-continental shelf, must
comply with the new rules. Order No. 639 creates additional significant
reporting requirements for us. The new reporting requirements could place us at
a competitive disadvantage relative to other offshore gatherers that are owned
by producers of natural gas because these other gatherers will have access to
our Order No. 639 reporting information but will have no reciprocal reporting
obligation. Additionally, the new rules provide that rates and conditions of
service acceptable under the Natural Gas Act for jurisdictional
outer-continental shelf pipelines may, nonetheless, be considered unlawful under
currently vague and undeveloped standards of discrimination under the Outer
Continental Shelf Lands Act. Order No. 639 may be altered on rehearing or on
appeal, and it is not known at this time what effect these new rules, as they
may be altered, will have on our business.

     Processing. The primary function of our natural gas processing plants is
the extraction of NGLs and the conditioning of natural gas for marketing. FERC
has traditionally maintained that a processing plant that primarily extracts
NGLs is not a facility for transportation or sale of natural gas for resale in
interstate commerce and therefore is not subject to its jurisdiction under the
Natural Gas Act. We believe that our natural gas processing plants are primarily
involved in removing NGLs and, therefore, are exempt from the jurisdiction of
FERC.

                                       55
<PAGE>   57

     Transportation and Sales of Natural Gas Liquids. We have non-operating
interests in two pipelines that transport NGLs in interstate commerce. The
rates, terms and conditions of service on these pipelines are subject to
regulation by the FERC under the Interstate Commerce Act. The Interstate
Commerce Act requires, among other things, that petroleum products (including
NGLs) pipeline rates be just and reasonable and non-discriminatory. The FERC
allows petroleum pipeline rates to be set on at least three bases, including
historic cost, historic cost plus an index or market factors.

     Sales of Natural Gas Liquids. Our sales of NGLs are not currently regulated
and are made at market prices. In a number of instances, however, the ability to
transport and sell such NGLs are dependent on liquids pipelines whose rates,
terms and conditions or service are subject to the Interstate Commerce Act.
Although certain regulations implemented by the FERC in recent years could
result in an increase in the cost of transporting NGLs on certain petroleum
products pipelines, we do not believe that these regulations affect us any
differently than other marketers of NGLs with whom we compete.

     U.S. Department of Transportation. Some of our pipelines are subject to
regulation by the U.S. Department of Transportation with respect to their
design, installation, testing, construction, operation, replacement and
management. Comparable regulations exist in some states where we do business.
These regulations provide for safe pipeline operations and include potential
fines and penalties for violations.

     Safety and Health. Certain federal statutes impose significant liability
upon the owner or operator of natural gas pipeline facilities for failure to
meet certain safety standards. The most significant of these is the Natural Gas
Pipeline Safety Act, which regulates safety requirements in the design,
construction, operation and maintenance of gas pipeline facilities. In addition,
we are subject to a number of federal and state laws and regulations, including
the federal Occupational Safety and Health Act and comparable state statutes,
whose purpose is to maintain the safety of workers, both generally and within
the pipeline industry. We have an internal program of inspection designed to
monitor and enforce compliance with pipeline and worker safety requirements. We
believe we are in substantial compliance with the requirements of these laws,
including general industry standards, recordkeeping requirements, and monitoring
of occupational exposure to hazardous substances.

     Canadian Regulation. Our Canadian assets in the province of Alberta are
regulated by the Alberta Energy and Utilities Board. Our West Doe natural gas
gathering pipeline, which crosses the Alberta/British Columbia border, falls
under the jurisdiction of the National Energy Board.

ENVIRONMENTAL MATTERS

     The operation of pipelines, plants and other facilities for gathering,
transporting, processing, treating, or storing natural gas, NGLs and other
products is subject to stringent and complex laws and regulations pertaining to
health, safety and the environment. As an owner or operator of these facilities,
we must comply with these laws and regulations at the federal, state, and local
levels. These laws and regulations can restrict or prohibit our business
activities that affect the environment in many ways, such as:

     - restricting the way we can release materials or waste products into the
       air, water, or soils;

     - limiting or prohibiting construction activities in sensitive areas such
       as wetlands or areas of endangered species habitat, or otherwise
       constraining how or when construction is conducted;

     - requiring remedial action to mitigate pollution from former operations,
       or requiring plans and activities to prevent pollution from ongoing
       operations; and

     - imposing substantial liabilities on us for pollution resulting from our
       operations, including, for example, potentially enjoining the operations
       of facilities if it were determined that they were not in compliance with
       permit terms.

     In most instances, the environmental laws and regulations affecting our
operations relate to the potential release of substances or waste products into
the air, water or soils, and include measures to control or prevent the release
of substances or waste products to the environment. Costs of planning,
designing, constructing and

                                       56

operating pipelines, plants, and other facilities must incorporate compliance
with environmental laws and regulation and safety standards. Failure to comply
with these laws and regulations may trigger a variety of administrative, civil
and criminal enforcement measures, which can include the assessment of monetary
penalties, the imposition of remedial requirements, the issuance of injunctions
and federally authorized citizen suits. Moreover, it is not uncommon for
neighboring landowners and other third parties to file claims for personal
injury and property damage allegedly caused by the release of substances or
other waste products to the environment. The following is a discussion of
certain environmental and safety concerns that relate to the midstream natural
gas and NGLs industry. It is not intended to constitute a complete discussion of
all applicable federal, state and local laws and regulations, or specific
matters, to which we may be subject.

     Our operations are regulated by the Clean Air Act, as amended, and
comparable state laws and regulations. These laws and regulations govern
emissions into the air from our activities, for example in relation to our
processing plants and our compressor stations, and also impose procedural
requirements on how we conduct our operations. Due to the nature or our
business, we have numerous permits related to air emissions issued by state
governments or the United States Environmental Protection Agency ("EPA"). For
example, we have a large number of federal Operating Permits, known as Title V
permits, for our facilities that can impart specific emissions limitations as
well as specific operational practices with which we must comply. There are also
other state and federal requirements that might relate to our operations,
including the federal Prevention of Significant Deterioration permitting
requirements for major sources of emissions, and specific New Source Performance
Standards or Maximum Achievable Control Technology ("MACT") Standards issued by
the EPA that apply specifically to our industry or activities. Our failure to
comply with these requirements exposes us to civil enforcement actions from the
state agencies and perhaps the EPA, including monetary penalties, injunctions,
conditions or restrictions on operations, and, potentially, criminal enforcement
actions or federally authorized citizen suits.

     On June 17, 1999, the EPA published in the Federal Register a final MACT
standard under Section 112 of the Clean Air Act to limit emissions of Hazardous
Air Pollutants ("HAPs") from oil and natural gas production as well as from
natural gas transmission and storage facilities. The MACT standard requires that
affected facilities reduce their emissions of HAPs by 95%, and this will affect
our various large dehydration units and potentially some of our storage vessels.
This new standard will require that we achieve this reduction by either process
modifications or installing new emissions control technology. The MACT standard
will affect us and our competitors in a like manner. The rule allows most
affected sources until at least June 2002 to comply with the requirements. While
additional capital costs are likely to result from this rule or other potential
air regulations, we believe that these changes will not have a material adverse
effect on our business, financial position or results of operations.

     Our operations generate wastes, including some hazardous wastes, that are
subject to the Resource Conservation and Recovery Act ("RCRA"), as amended and
comparable state laws. However, RCRA currently exempts many natural gas
gathering and processing plant wastes from being subject to hazardous waste
requirements. Specifically, RCRA excludes from the definition of hazardous waste
produced waters and other wastes associated with the exploration, development,
or production of crude oil, natural gas or geothermal energy. Unrecovered
petroleum product wastes, however, may still be regulated under RCRA as solid
waste. Moreover, ordinary industrial wastes, such as paint wastes, waste
solvents, laboratory wastes, and waste compressor oils, may be regulated as
hazardous waste. Natural gas and NGLs transported in pipelines may also generate
some hazardous wastes. Although we believe it is unlikely that the RCRA
exemption will be repealed in the near future, repeal would increase costs for
waste disposal and environmental remediation at our facilities. Past operations
are identified from time to time as having used polychlorinated biphenyls
("PCBs"), for example, in plant air compressor systems, and when identified we
are required to address or remediate such a system that might contain PCBs in
compliance with the Toxic Substances Control Act, including any contamination
that might be associated with a release from that system.

     Our operations could incur liability under the Comprehensive Environmental
Response, Compensation and Liability Act of 1980, as amended ("CERCLA"), also
known as "Superfund," and comparable state laws or other federal laws regardless
of our fault, in connection with the disposal or other release of hazardous
substances or wastes, including those arising out of historical operations
conducted by our predecessors. If we
                                       57
<PAGE>   59

were to incur liability under CERCLA, we could be subject to joint and several
liability for the costs of cleaning up hazardous substances, for damages to
natural resources and for the costs of certain health studies.

     We currently own or lease, and have in the past owned or leased, numerous
properties that for many years have been used for the measurement, gathering,
field compression and processing of natural gas and NGLs. Although we used
operating and disposal practices that were standard in the industry at the time,
hydrocarbons or wastes may have been disposed of or released on or under the
properties owned or leased by us or on or under other locations where such
wastes have been taken for disposal. In addition, some of these properties have
been operated by third parties whose treatment and disposal or release of
hydrocarbons or other wastes was not under our control. These properties and the
wastes disposed on them may be subject to CERCLA, RCRA and analogous state laws.
Under such laws, we could be required to remove or remediate previously disposed
wastes (including waste disposed of or released by prior owners or operators) or
property contamination (including groundwater contamination, whether from prior
owners or operators or other historic activities or spills) or to perform
remedial plugging or pit closure operations to prevent future contamination, in
some instances regardless of fault or the amount of waste we sent to the site.

     EPA Region VIII issued a RCRA administrative cleanup order in 1995 with
respect to the operation of the Weld County Waste Disposal, Inc. site near Fort
Lupton Colorado, and in 1997 one of our predecessors was identified along with
other entities as a potentially responsible party for this site. We are not
aware of administrative activity at this site in the last two years. We have
various ongoing remedial matters related to historical operations similar to
others in the industry, for the reasons generally described above. These are
typically managed in conjunction with the relevant state or federal agencies to
address specific conditions, and in some cases are the responsibility of other
entities based upon contractual obligations related to the assets. In April
1999, we acquired the midstream natural gas gathering and processing assets of
Union Pacific Resources located in several states, which include 18 natural gas
plants and 365 gathering facility sites. We have entered into an agreement to
transfer liability for pre-April 1999 soil and ground water conditions
identified as part of this transaction to a third party environmental/insurance
partnership for a one-time premium payment subject to certain deductibles. With
respect to these identified environmental conditions, the environmental partner
has assumed liability and management responsibility for environmental
remediation, and the insurance partner is providing financial management,
program oversight, remediation cost cap insurance coverage for a 30 year term,
and pollution legal liability coverage for a 20 year term. This innovative
approach promotes pro-active site cleanup and closure, reduces internal resource
needs for managing remediation, and may improve the marketability of assets
based on transferability of this insurance coverage. In August 1996, we acquired
certain gas gathering and processing assets in three states from Mobil
Corporation. Under the terms of the asset purchase agreement, Mobil has retained
the liabilities and costs related to various pre-August 1996 environmental
conditions that were identified with respect to those assets. Mobil has
formulated or is in the process of developing plans to address certain of these
conditions, which we will review and monitor as clean-up activities proceed.

     Our operations can result in discharges of pollutants to waters. The
Federal Water Pollution Control Act of 1972, as amended ("FWPCA"), also known as
the Clean Water Act, and analogous state laws impose restrictions and strict
controls regarding the discharge of pollutants, including NGLs or unpermitted
wastes, into state waters or waters of the United States. The unpermitted
discharge of pollutants such as from spill or leak incidents are prohibited. The
FWPCA and regulations implemented thereunder also prohibit discharges of fill
material and certain other activities in wetlands unless authorized by an
appropriately issued permit. Any unexpected release of NGLs or condensates from
our systems or facilities could result in significant remedial obligations as
well as FWPCA-related fines or penalties.


     We make expenditures in connection with environmental matters as part of
our normal operations and capital expenses. For each of 2000 and 2001, we
estimate that our expensed and capital-related costs will be approximately $13
million. It should be noted, however, that stricter laws and regulations, new
interpretations of existing laws and regulations, or new information or
developments could significantly increase our compliance costs and remediation
obligations.


                                       58
<PAGE>   60

     We are subject to inherent environmental and safety risks related to our
handling of natural gas and NGL products and historical industry waste disposal
practices. We cannot assure you that we will not incur material environmental
costs and liabilities. We believe, based on our current knowledge, that we are
generally in substantial compliance with all of our necessary and material
permits, and that we are in substantial compliance with applicable material
environmental and safety regulations. We also use contractual measures, such as
the environmental/insurance partnership discussed above, where appropriate to
mitigate environmental claims or losses but, in the event of a default, we could
be exposed to these claims. Based on current information and taking into account
protective mechanisms mentioned here, we do not believe that compliance with
federal, state or local environmental laws and regulations will have a material
adverse effect on our business, financial position or results of operations. In
addition, we believe that the various environmental activities in which we are
presently engaged are not expected to materially interrupt or diminish our
operational ability to gather, process, and transport natural gas and NGLs. We
cannot assure you, however, that future events, such as changes in existing
laws, the promulgation of new laws, or the development or discovery of new facts
or conditions will not cause us to incur significant costs.

     Our natural gas gathering pipelines and processing plants in Alberta,
Canada operate under permits from and are regulated by Alberta Environment. Our
West Doe natural gas gathering pipeline, which crosses the Alberta/British
Columbia border, is regulated by the National Energy Board in consultation with
the Canadian Environmental Assessment Agency.

LEGAL PROCEEDINGS

     In November 1997, Chevron U.S.A. sued GPM Gas Corporation, one of our
subsidiaries, in the United States District Court for the Western District of
Texas, Midland Division, for alleged breach by GPM Gas Corporation of favored
nations clauses in several 1961 gas supply contracts. The case was tried in
October 1998, and in September 1999, the trial court issued an opinion and final
judgment against GPM for $13.8 million through July 1998, plus attorneys' fees
and interest for the period after July 1998. GPM Gas Corporation has appealed
the judgment to the U.S. Court of Appeals for the Fifth Circuit.

     In recent years, the midstream natural gas industry has seen an increase in
the number of class actions in suits involving royalty disputes, mismeasurement
and mispayment. Although the industry has seen these types of cases before, they
were previously typically brought by a single plaintiff or small group of
plaintiffs. Many of these cases are now being brought as class actions or under
the Civil False Claims Act. We are currently named defendants in a number of
these types of cases. Although we believe we have meritorious defenses to these
cases and will continue to vigorously defend against them, these class actions
are expected to be costly and time consuming to defend.

     In addition to the foregoing, from time to time, we are named as parties in
legal proceedings arising in the ordinary course of our business. We believe we
have meritorious defenses to all of these lawsuits and legal proceedings and
will vigorously defend against them. Based on our evaluation of pending matters
and after consideration of reserves established, we believe that the resolution
of these proceedings will not have a material adverse effect on our business,
financial position or results of operations.

EMPLOYEES

     As of February 29, 2000, we had approximately 2,700 employees. We are a
party to two collective bargaining agreements which cover an aggregate of
approximately 180 of our employees and are bound to negotiate in good faith
toward collective bargaining agreements with two other collective bargaining
units which cover an aggregate of approximately 80 employees. We believe our
relations with our employees are good.

EMPLOYMENT AND CONSULTING AGREEMENTS

     We have entered into an employment agreement with Mr. Panatier which
provides for a term of two years from the closing of the Combination. During the
term of this employment agreement, Mr. Panatier will receive a monthly salary of
$32,000, which may be increased upon the recommendation of our Compensation
Committee. The agreement also provides for a target bonus of 60% of Mr.
Panatier's annual base salary. Mr. Panatier is entitled to participate in all
our benefit plans on the same basis as other similarly-situated executives of
our company.


     Mr. Panatier will also receive annual long-term incentive awards in the
form of stock option grants with a value equal to 150% of his annual base salary
and restricted stock awards with a value equal to 70% of his annual base salary.
While the specific terms of these awards will generally be determined by our
Compensation Committee, any awards made during the initial term of this
agreement will vest on the second anniversary of the completion of the offering.
The employment agreement also provides for a restricted stock retention award,
to be valued at 250% of his annual base salary, to be granted on the completion
of the offering. This restricted stock award vests 50% on the first anniversary
of the effective date of the employment agreement and 50% on the second
anniversary if Mr. Panatier is employed on the scheduled vesting date.


                                       64
<PAGE>   66


     If we terminate Mr. Panatier's employment for any reason other than death,
disability or cause or if Mr. Panatier terminates his employment for cause, all
long-term incentive awards and his restricted stock awards will immediately
vest. In addition, if a change of control of our company occurs during the term
of the employment agreement and Mr. Panatier is terminated without cause or Mr.
Panatier terminates his employment with cause, Mr. Panatier will also be
entitled to a lump sum severance payment equal to 200% of his annual salary in
effect at the time, plus his target bonus and to participate in our group
medical plan (unless Mr. Panatier is eligible for coverage by a subsequent
employer) for a period of two years following such termination.



     We have entered into a contract for consulting services with Mr. Slaughter
which terminates in June 2002. During the term of this contract, Mr. Slaughter
will receive a quarterly retainer of $46,860, in exchange for which Mr.
Slaughter has agreed to perform services for us for up to 30 days per quarter.
If Mr. Slaughter works more than 30 days per quarter, he is entitled to
additional compensation at the rate of $1,562 for each additional day. The
contract also provides for compensation of $360,000 to Mr. Slaughter in the form
of stock options and/or restricted stock upon the completion of the offering.


2000 LONG-TERM INCENTIVE PLAN


     General. We have adopted a Long-Term Incentive Plan. The plan allows us to
grant incentive awards to our employees, consultants and independent directors
(including employees and consultants of our subsidiaries). The plan provides for
the grant of:


     - stock options (including both incentive stock options and nonqualified
       stock options);

     - stock appreciation rights;

     - restricted stock;

     - performance awards;

     - phantom stock awards (i.e., awards that give the recipient the right to
       receive payment, whether in stock or cash, at the end of a fixed vesting
       period based on the difference between the value of our common stock at
       the time of grant and the time of vesting); and

     - dividend equivalents.

     The purpose of the plan is to strengthen our ability to attract, motivate
and retain employees and directors and to provide an additional incentive for
employees.


     Reservation of Shares. We have reserved 4,000,000 shares of common stock
for issuance under the plan, provided that no more than 400,000 shares of common
stock may be issued in connection with all awards of restricted stock,
performance awards or phantom stock under the plan. The shares of common stock
to be issued under the plan will be made available from authorized but unissued
shares of common stock. If any shares of common stock that are the subject of an
award are not issued and cease to be issuable for any reason, such shares will
no longer be charged against such maximum share limitation and may again be made
subject to awards under the plan. In the event of certain corporate
reorganizations, recapitalizations, or other specified corporate transactions
affecting us or our common stock, proportionate adjustments may be made to the
number of shares available for grant under the plan, the applicable maximum
share limitations under the plan, and the number of shares and prices under
outstanding awards at the time of the event.



     Administration. The plan will be administered by the Compensation
Committee, or such other committee or subcommittee of the Board of Directors as
it designates. Subject to certain limitations, the committee has the authority
to determine the persons (other than nonemployee directors) to whom awards are
granted, the types of awards to be granted, the time at which awards will be
granted, the number of shares, units or other rights subject to each award, the
exercise, base or purchase price of an award (if any), the time or times at
which the award will become vested, exercisable or payable, and the duration of
the award. The committee also has the power to interpret the plan and make
factual determinations and may provide for the


                                       65
<PAGE>   67

acceleration of the vesting or exercise period of an award at any time prior to
its termination or upon the occurrence of specified events.

     Change in Control. The committee may provide in an individual award
agreement for the effect of a "change in control" (as defined in the plan) upon
an award granted under the plan. Such provisions may include:


     - the acceleration, limitation, or extension of time periods for purposes
       of exercising, vesting in, or realizing gain from an award;


     - the waiver or modification of performance or other conditions related to
       payment or other rights under an award;

     - providing for the cash settlement of an award; or

     - such other modification or adjustment to an award as the committee deems
       appropriate.


     Term and Amendment. The plan has a term of ten years, subject to earlier
termination or amendment by our Board of Directors. The Board of Directors may
amend the plan at any time, except that stockholder approval is required for
amendments that would change the persons eligible to participate in the plan,
increase the number of shares of common stock reserved for issuance under the
plan, allow the grant of options at an exercise price below fair market value.


     2000 Plan Benefits. Currently, all employees are expected to be considered
by the committee for participation in the plan. The number of persons eligible
to participate in the plan and the number of grantees may vary from year to
year.


     Concurrently with the offering, options to purchase approximately 958,000
shares of our common stock at the initial public offering price are expected to
be granted to our officers and employees. Of these options, approximately
211,500 shares are expected to be granted to our Named Executive Officers. Also
concurrently with the offering, restricted stock awards of approximately 110,500
shares are expected to be granted to our officers and employees, of which
approximately 33,000 are expected to be granted to our Named Executive Officers.
In addition, an initial grant of a restricted stock award for 10,000 shares is
expected to be granted to each non-employee director upon his or her election.


OPTION GRANTS IN LAST FISCAL YEAR


     In the fiscal year ended December 31, 1999, none of the Named Executive
Officers received options to purchase our common stock, nor were they entitled
to exercise any such stock options. None of the Named Executive Officers held
options to purchase our common stock at December 31, 1999.

                   RELATIONSHIP WITH DUKE ENERGY AND PHILLIPS


     On March 31, 2000, we combined the midstream natural gas businesses of Duke
Energy and Phillips. In connection with the Combination, Phillips transferred
all of its interest in its subsidiaries that conducted its midstream natural gas
business to Field Services LLC, our subsidiary that was formed in December 1999
to hold all of Duke Energy's gas gathering and processing business. In
connection with the Combination, Duke Energy and Phillips also transferred to
Field Services LLC the midstream natural gas assets acquired by Duke Energy or
Phillips prior to consummation of the Combination, including Mid-Continent
gathering and processing assets of Conoco and Mitchell Energy. In addition,
concurrently with the Combination, we obtained by transfer from Duke Energy the
general partner of TEPPCO. In exchange for the asset contribution, Phillips
received 30.3% of the member interests in Field Services LLC, with Duke Energy
indirectly, through us, holding the remaining 69.7% of the outstanding member
interests. In connection with the closing of the Combination, Field Services LLC
borrowed approximately $2.8 billion and made one-time cash distributions
(including reimbursements for acquisitions) of approximately $1.5 billion to
Duke Energy and approximately $1.2 billion to Phillips.



     Concurrently with the consummation of the offering of common stock, the
subsidiary of Phillips that indirectly holds Phillips' interests in Field
Services LLC will be merged into us, and we will issue shares of our common
stock to Phillips. After the merger and completion of the offering of common
stock, Duke Energy and Phillips together will own approximately 81.24% of our
outstanding common stock (assuming the underwriters do not exercise their
over-allotment option). The exact allocation between Duke Energy and Phillips of
shares of our common stock will be determined by the average of the closing
prices of our common stock on its first five trading days on the New York Stock
Exchange Composite Tape. Assuming that the five-day average price is the same as
the assumed initial public offering price, following the offering, Duke Energy
will own approximately 58.65% and Phillips will own approximately 22.59% of our
outstanding common stock (assuming the underwriters do not exercise their
over-allotment option). Although the exact allocation may vary, Duke Energy
will, in all events, continue to control our company through its share ownership
and representation on our Board of Directors.


     There are significant transactions and relationships between us, Duke
Energy and Phillips. For purposes of governing these ongoing relationships and
transactions, we will enter into, or continue in effect, the agreements
described below. We intend that the terms of any future transactions and
agreements between us and Duke Energy or Phillips will be at least as favorable
to us as could be obtained from third parties. We will advise our Board of
Directors in advance of any such proposed transactions or agreements with Duke
Energy or Phillips that are material to us. In evaluating these terms and
provisions, our Board of Directors will use appropriate procedures in light of
the Board's fiduciary duties. Depending on the nature and size of the particular
transaction, in any such reviews, our Board of Directors may rely on our
management's knowledge, use outside experts or consultants, secure appropriate
appraisals, refer to industry statistics or prices, or take other actions as are
appropriate under the circumstances.

TRANSACTIONS WITH DUKE ENERGY

     SERVICES AGREEMENT


     We have entered into a Services Agreement with Duke Energy and some of its
subsidiaries, dated as of March 14, 2000. Under this agreement, Duke Energy and
those subsidiaries will provide us with various staff and support services,
including information technology products and services, payroll, employee
benefits, corporate insurance, cash management, ad valorem taxes and shareholder
services. The above services are priced on the basis of a monthly charge.
Additionally, we may use other Duke Energy services subject to hourly rates,
including legal, internal audit, tax planning, human resources and security
departments. This agreement expires on December 31, 2000. We believe that
overall charges under this agreement will not exceed charges we would have
incurred had we obtained similar services from outside sources.


                                       67
<PAGE>   69

     LICENSE AGREEMENT


     Duke Energy has licensed to us a non-exclusive right to use the word "Duke
Energy" and its logo and certain other trademarks in identifying our businesses.
This right may be terminated by Duke Energy at its sole option any time after:


     - Duke Energy's direct or indirect ownership interest in our company is
       less than or equal to 35%; or

     - Duke Energy no longer controls, directly or indirectly, the management
       and policies of our company.


     Following the receipt of Duke Energy's notice of termination, we have
agreed to amend our organizational documents and those of our subsidiaries to
remove the "Duke" name and to phase out within 180 days of the date of the
notice the use of existing signage, printed literature, sales and other
materials bearing a name, phrase or logo incorporating "Duke."


     DUKE CAPITAL CORPORATION CREDIT AGREEMENT

     Effective April 4, 2000, Field Services LLC entered into a $100 million
revolving credit agreement with Duke Capital Corporation, an indirect,
wholly-owned subsidiary of Duke Energy. The revolving credit agreement will be
used for short-term financing requirements. At April 30, 2000, there were no
amounts outstanding under this facility. The agreement terminates on May 31,
2000, and bears interest at the Bank of America prime rate.

     TRANSACTIONS PRIOR TO THE COMBINATION

     Transactions between Duke Energy and Phillips' midstream natural gas
business. Prior to the Combination, Duke Energy and its subsidiaries engaged in
a number of transactions with the subsidiaries of Phillips that were transferred
to us in the Combination, including GPM Gas Corporation (the "Phillips Combined
Subsidiaries"). These transactions were entered into in the ordinary course of
Duke Energy's and the Phillips Combined Subsidiaries' business and were related
to the purchase and sale of raw natural gas, residue gas and NGLs at market
prices.

     Transactions between Duke Energy and the Predecessor Company. Prior to the
Combination, Duke Energy and its subsidiaries engaged in a number of
transactions with the Predecessor Company. The following is a description of
those transactions.

     The Predecessor Company historically sold a portion of its residue gas and
NGLs to Duke Energy and its subsidiaries, including Duke Energy Trading and
Marketing, at contractual prices that approximated market prices. The
Predecessor Company's revenues from such sales were approximately $567.8 million
in 1997, $536.3 million in 1998 and $696.7 million in 1999. We anticipate that
we will continue to sell residue gas and NGLs to Duke Energy and its
subsidiaries (including Duke Energy Trading and Marketing) at market prices in
the ordinary course of our business.

     The Predecessor Company historically purchased residue gas from Duke Energy
and its subsidiaries at contractual prices that approximated market prices. The
Predecessor Company's purchases of raw natural gas and other petroleum products
from Duke Energy and its subsidiaries totaled $48.9 million in 1997, $79.6
million in 1998 and $128.6 million in 1999. We anticipate that we will continue
to purchase residue gas and other petroleum products at market prices from Duke
Energy and its subsidiaries in the ordinary course of our business.

     The Predecessor Company historically provided gathering and transportation
services over its gathering systems and pipelines to Duke Energy and its
subsidiaries at market prices. The Predecessor Company generated no revenues in
1997, $6.4 million in 1998 and $2.7 million in 1999 from the provision of such
services. We anticipate that we will continue to provide gathering and
transportation to Duke Energy and its subsidiaries at market prices in the
ordinary course of our business.

     Duke Energy has historically provided the Predecessor Company with various
support services, including information technology services, accounting, legal,
insurance, payroll, cash management, risk management
                                       68
<PAGE>   70

and welfare benefits services. Duke Energy has historically billed the
Predecessor Company for such services at prices that approximate their cost to
provide such services. The Predecessor Company was charged $11.7 million in
1997, $12.1 million in 1998 and $19.1 million in 1999 for such services. Duke
will continue to provide some of these services under the terms of the Services
Agreement described above.


     On June 30, 1995, the Predecessor Company issued a $101.6 million note to
Duke Energy. The note was scheduled to mature in 2004 and bore interest at 8.5%.
In addition, on December 31, 1996, the Predecessor Company issued a $540 million
note to Duke Energy. The note matured at the end of each year and was extended
for subsequent one year periods at each year end. The note bore interest at
prime rate, adjusted quarterly. Upon consummation of the Combination, these
notes were capitalized to equity.


TRANSACTIONS WITH PHILLIPS

     TRANSITION SERVICES AGREEMENT


     We have entered into a Transition Services Agreement with Phillips, dated
as of March 17, 2000. Under this agreement, Phillips will provide us with
various staff and support services, including information technology products
and services, cash management, real estate, claims and property tax services.
The above services are priced on the basis of a monthly charge equal to
Phillips' fully-burdened cost of providing the services. This agreement expires
on December 31, 2000.


     TRANSACTIONS PRIOR TO THE COMBINATION

     Transactions between Phillips and Duke Energy's midstream natural gas
business. Prior to the Combination, Phillips engaged in a number of transactions
with the Predecessor Company. These transactions were entered into in the
ordinary course of Phillips' and the Predecessor Company's business and were
related to the purchase and sale of raw natural gas, residue gas and NGLs at
market prices.

     Transactions between Phillips and its midstream natural gas business. Prior
to the Combination, Phillips engaged in a number of transactions with GPM Gas
Corporation. The following is a description of those transactions.

     GPM Gas Corporation, the subsidiary of Phillips that owned its midstream
natural gas assets that were contributed to us in the Combination, and Phillips
66 Company, a division of Phillips, entered into an NGL Output Purchase and Sale
Agreement effective as of January 1, 2000. The agreement allows Phillips 66
Company to purchase at index-based prices approximately all of the NGLs produced
by the processing plants owned by GPM Gas Corporation prior to the Combination.
The agreement also grants Phillips 66 Company the right to purchase at
index-based prices certain quantities of NGLs produced at processing plants that
are acquired and/or constructed by us in the future in various counties in the
Mid-Continent and Permian Basin regions and the Austin Chalk area. The agreement
has a 15-year primary term and a four-year phase-down period. The agreement
prohibits us from modifying our normal business practices to divert or reduce
NGLs available for purchase by Phillips 66 Company from current delivery levels.

     GPM Gas Corporation historically sold a portion of its residue gas and
other by-products to Phillips at contractual prices that approximated market
prices. In addition, GPM Gas Corporation sold NGLs to Phillips at prices based
upon quoted market prices for fractionated NGLs, less transportation,
fractionation and quality-adjustment fees. GPM Gas Corporation's operating
revenues from the sale of residue gas, other by-products and NGLs to Phillips
were approximately $758.7 million in 1997, $537.5 million in 1998 and $725.5
million in 1999. We anticipate that we will continue to sell residue gas and
NGLs to Phillips and its subsidiaries or co-venturers at market prices in the
ordinary course of our business, including in connection with our long term
contract with Phillips described above.

     The Phillips Combined Subsidiaries historically purchased raw natural gas
from Phillips at contractual prices that approximated market prices. The
Phillips Combined Subsidiaries' purchases of raw natural gas from Phillips
totaled $118.8 million in 1997, $76.6 million in 1998 and $100.3 million in
1999. We anticipate that we will continue to purchase raw natural gas from
Phillips at market prices in the ordinary course of our business.

                                       69
<PAGE>   71


     Phillips historically provided the Phillips Combined Subsidiaries with
various field services and other general administrative services including
insurance, personnel administration, employee benefits, office space,
communications, data processing, engineering, automotive and other field
equipment, and other miscellaneous services, including legal, treasury,
planning, tax, auditing and other corporate services. These services were priced
to reimburse Phillips for its actual costs to provide the services. Charges for
these services and benefits were $12.1 million in 1997, $12.1 million in 1998
and $11.4 million in 1999. These services were terminated upon consummation of
the Combination other than as provided in the Transition Services Agreement.



     Phillips 66 Company, has historically purchased sulfur from GPM Gas
Corporation under an agreement for sulfur sales that is renewed annually.
Phillips 66 Company's purchases of sulfur from GPM Gas Corporation totaled
$446,000 in 1997, $412,000 in 1998 and $1.1 million in 1999. Phillips 66 Company
will continue to purchase sulfur from GPM Gas Corporation under the terms of the
agreement currently in effect.



     Prior to the Combination, all operational and personnel requirements of the
Phillips Combined Subsidiaries were met by Phillips' employees. All services
provided by Phillips were priced to cover the actual costs of these services,
which equaled $76.6 million in 1997, $74.8 million in 1998 and $74.9 million in
1999. These services were terminated when we hired most of the employees of the
Phillip Combined Subsidiaries in connection with the Combination.


     The Phillips Combined Subsidiaries earned interest of $2.7 million in 1997,
$2.4 million in 1998 and $2.5 million in 1999 from participation in Phillips'
centralized cash management system. Participation in the system was terminated
upon the completion of the Combination.

     Phillips Gas Company had long-term borrowings from Phillips and other
liabilities outstanding to Phillips of $655.0 million at the end of 1997, $560.0
million at the end of 1998 and $1,350.0 million at the end of 1999. Phillips Gas
Company incurred interest expense of $20.3 million in 1997, $35.9 million in
1998 and $35.6 million in 1999 on these borrowings. Included in the $1,350.0
million of borrowings outstanding at the end of 1999 is a $780.0 million
dividend from Phillips Gas Company to Phillips in the form of a note payable.
These borrowings from Phillips were paid at the closing of the Combination.


     The Phillips Combined Subsidiaries historically provided Phillips with
other minor administrative services. Costs allocated to Phillips for these
services were $120,000 in 1997, $79,000 in 1998 and $72,000 in 1999. These
services were terminated upon the consummation of the Combination other than as
provided in the Transition Services Agreement.


     The Phillips Combined Subsidiaries periodically bought from, or sold to,
Phillips various assets in the operation of its business. These net acquisitions
totaled $22,000 in 1997, $60,000 in 1998 and $239,000 in 1999.

     Immediately prior to the consummation of the offering, Duke Energy Natural
Gas Corporation, the subsidiary of Duke Energy that will hold all of Duke
Energy's shares of our common stock, and Phillips will enter into a shareholders
agreement covering the matters discussed below. The shareholders agreement will
terminate on the first date that either of Duke Energy or Phillips owns less
than 20% of our outstanding common stock. Duke Energy and Phillips have agreed
to cause each of their subsidiaries that hold shares of our common stock to
execute the shareholders agreement and to comply with the obligations of the
parties to the shareholders agreement.


     ELECTION OF DIRECTORS

     Each of Duke Energy and Phillips will agree to vote its shares of common
stock to elect seven directors designated by Duke Energy, so long as Duke Energy
owns at least 30% of our outstanding common stock, and four directors designated
by Phillips, so long as Phillips owns at least 20% of our outstanding common
stock. If Duke Energy owns less than 30% but at least 20% of our outstanding
common stock, the number of Duke Energy designees elected will be
proportionately reduced and the number of Phillips designees elected will be
proportionately increased. The shareholders agreement requires that Duke Energy
and Phillips together
                                       70
<PAGE>   72


include in their director designees a total of three individuals who are not
officers, directors or employees of Duke Energy, Phillips or any of their
affiliates. Duke Energy has designated two of these independent directors, and
Phillips has designated one. In addition, each of Duke Energy and Phillips have
agreed to vote to remove any director designee of the other upon the request of
the other at any time with or without cause.


     SPECIAL BUYOUT RIGHT


     After the first anniversary of the completion of the offering, Duke Energy
will have the right to acquire all (but not less than all) of the common stock
owned by Phillips at an appraised fair market value of such shares if, on three
separate occasions within 18 months, certain specified actions (which are
described in the first five bullet points under "Description of Capital
Stock -- Supermajority Requirements") have failed to receive the approval of our
Board of Directors. Duke Energy will be entitled to exercise this right only if
each of its designated directors and none of Phillips' designated directors
voted in favor of such actions.


     RIGHT OF FIRST REFUSAL

     If Duke Energy or Phillips desires to sell all or any portion of its shares
of our common stock (other than in connection with a registered public
offering), the non-selling party will have a right of first refusal to purchase
all (but not less than all) of the shares that the selling party desires to
transfer, on the same terms and conditions as those set forth in the notice of
the proposed transfer.

     CHANGE OF CONTROL


     If Duke Energy or Phillips or any of their affiliates that hold our common
stock undergoes a specified type of change of control, the other party will have
the right to purchase the shares in our company owned by the entity experiencing
the change of control at an appraised fair market value of such shares.


REGISTRATION RIGHTS AGREEMENT


     Upon completion of the offering, we will enter into a registration rights
agreement with Duke Energy and Phillips. This agreement will give each of Duke
Energy and Phillips the right, on two occasions, to demand that we register all
or any portion of their shares of our common stock for sale under the Securities
Act. Any demand to register shares must cover at least 3% of our common stock
then outstanding. Further, if we propose to register any of our common stock
under the Securities Act, Duke Energy and Phillips will have the right to
include their shares of common stock in the registration subject to certain
limitations. Despite a registration demand by either Duke Energy or Phillips, we
may delay registering their shares of our common stock for a reasonable time not
to exceed 180 days if, in the judgment of our Board, filing the registration
statement would require the disclosure of pending or contemplated matters or
information which would:


     - likely be detrimental to our company;

     - materially interfere with our business; or

     - materially interfere with a pending or contemplated material transaction.


     Furthermore, Duke Energy and Phillips may not require us to file a
registration statement within 120 days after the effectiveness of a registration
statement related to a demand registration made by Duke Energy or Phillips and
within 180 days after the effectiveness of any other registration statement in
which Duke Energy or Phillips was offered to participate.


     We have agreed to cooperate fully in connection with any such registration
and with any offering made in connection with such registration. In addition, we
have agreed to pay all costs and expenses (other than fees, discounts and
commissions of underwriters, brokers and dealers; capital gains, income and
transfer taxes (if any); and the fees and disbursements of counsel to Duke
Energy or Phillips) related to the registration and sale of shares of our common
stock by Duke Energy or Phillips in any registered offering. The rights of Duke
Energy and Phillips under the registration rights agreement are assignable under
certain circumstances. The

                                       71
<PAGE>   73

rights of each of Duke Energy and Phillips under the registration rights
agreement terminate at any time when they and their affiliates own less than 10%
of our outstanding common stock.

CONFLICTS OF INTEREST


     Generally, directors and officers have a fiduciary duty to manage their
company in a manner beneficial to the company and its stockholders. The majority
of our directors and officers are either current or former directors or officers
of Duke Energy or Phillips, and four of our officers or directors are directors
of the general partner of TEPPCO. In certain circumstances, an action beneficial
to Duke Energy, Phillips or TEPPCO may be detrimental to our interests. Given
the shared directors and officers these circumstances may create conflicts of
interest. Additionally, our extensive relationships with Duke Energy and
Phillips also may result in conflicts of interest.



     In order to mitigate potential conflicts of interest, as long as Duke
Energy and Phillips each own at least 20% of our voting stock, any future
transactions between our company and Duke Energy, Phillips or any of their
affiliates, which are on terms that are clearly less favorable terms than those
that are within the range of comparable transactions between unaffiliated third
parties, must be approved by eight of our 11 directors.


                                       72
<PAGE>   74

                             PRINCIPAL STOCKHOLDERS

     The following table sets forth information regarding the beneficial
ownership of our common stock, by:

     - each holder of more than 5% of our common stock;

     - our Chief Executive Officer and each of our next five most highly
       compensated executive officers;

     - each director and director nominee; and

     - all directors, director nominees and executive officers as a group.


The exact allocation of shares of common stock between Duke Energy and Phillips
will be determined based on the average of the closing prices of our common
stock on the New York Stock Exchange Composite Tape on its first five trading
days. For purposes of the table set forth below the number of shares of common
stock to be beneficially owned by each of Duke Energy and Phillips has been
estimated based upon an assumed initial public offering price of $21.00. Unless
otherwise stated in the notes to the table, each of the stockholders has sole
voting and investment power with respect to the shares of common stock
beneficially owned by it. The table below does not include the approximate
110,500 shares of common stock that are expected to be issued concurrently with
the offering under restricted stock grants.

(2) Mr. Priory serves as Chairman, President and Chief Executive Officer of Duke
    Energy. As such, Mr. Priory may be deemed to have voting and dispositive
    power over the shares beneficially owned by Duke Energy. Mr. Priory
    disclaims beneficial ownership of the securities owned by Duke Energy.


                          DESCRIPTION OF CAPITAL STOCK


     After our offering, our authorized capital stock will consist of
500,000,000 shares of common stock, par value $.01 per share, and 10,000,000
shares of preferred stock, par value $.01 per share. Immediately following the
offering, 140,752,211 shares of common stock and no shares of preferred stock
will be issued and outstanding.


COMMON STOCK


     Holders of our common stock are entitled to one vote per share on all
matters to be voted upon by the stockholders. Holders of common stock do not
have cumulative voting rights. As a result, the holders of a majority of the
shares of our common stock can elect all of the members of the Board of
Directors, subject to the rights, powers and preferences of any outstanding
series of preferred stock. Subject to preferences of any preferred stock that
may be issued, the holders of our common stock are entitled to receive such
dividends as may be declared by the Board of Directors. The common stock is
entitled to receive pro rata all of our assets available for distribution to our
stockholders in liquidation, subject to the rights and preferences of any
outstanding series of preferred stock. There are no redemption or sinking fund
provisions applicable to the common stock. All outstanding shares of common
stock are fully paid and non-assessable.


PREFERRED STOCK

     Subject to the provisions of the certificate of incorporation and
limitations prescribed by law, our Board of Directors has the authority to issue
up to 10,000,000 shares of preferred stock in one or more series and to fix the
rights, preferences, privileges and restrictions thereof, including dividend
rights and rates, conversion rates, voting rights, redemption terms and prices,
liquidation preferences and the number of shares constituting any series or the
designation of such series, which may be superior to those of the common stock,
without further vote or action by the stockholders.


     The issuance of shares of preferred stock under the Board of Directors'
authority described above may adversely affect the rights of the holders of our
common stock. For example, preferred stock may rank prior to the common stock
with respect to dividend rights, liquidation preference or both, may have full
or limited voting rights and may be convertible into shares of common stock.
Accordingly, the issuance of shares of preferred stock may discourage bids for
our common stock or may otherwise adversely affect the market price of our
common stock. In addition, the preferred stock may enable our Board of Directors
to render more difficult or to discourage attempts by others to obtain control
of our company through a hostile tender offer, proxy contest, merger or
otherwise.


ANTI-DILUTION RIGHTS


     If we sell shares of our common stock or shares of any other previously
issued and outstanding capital stock in a public offering (other than in
connection with an employee compensation or benefit plan or program approved by
our Board of Directors in accordance with our bylaws), our certificate of
incorporation provides that Duke Energy and Phillips each have the right to
purchase the number of shares necessary to maintain their ownership percentages
in that class of securities. In order to exercise this right, Duke Energy or
Phillips must each own, directly or indirectly, at least 20% of all outstanding
shares of our common stock. So long as Duke Energy and Phillips each own at
least 20% of all outstanding common stock, any proposed amendment to these
rights requires the consent of both Duke Energy and Phillips.


                                       74
<PAGE>   76

ANTI-TAKEOVER PROVISIONS OF OUR CERTIFICATE OF INCORPORATION AND BYLAWS

     Our certificate of incorporation and bylaws contain several provisions that
could delay or make more difficult the acquisition of us through a hostile
tender offer, open market purchases, proxy contest, merger or otherwise.

     WRITTEN CONSENT OF STOCKHOLDERS

     Our certificate of incorporation provides that, on and after the date when
Duke Energy ceases to own (directly or indirectly) a majority of the shares of
our outstanding securities entitled to vote in the election of directors, any
action by our stockholders must be taken at an annual or special meeting of
stockholders. Until that date, any action required or permitted to be taken by
our stockholders may be taken at a duly called meeting of stockholders or by the
written consent of stockholders owning the minimum number of shares required to
approve the action.

     SPECIAL MEETINGS OF STOCKHOLDERS

     Subject to the rights of the holders of any series of preferred stock
approved by our Board of Directors, our by-laws provide that special meetings of
the stockholders may only be called by the Chairman of the Board of Directors or
by the resolution of a majority of our Board of Directors.

     ADVANCE NOTICE PROCEDURE FOR DIRECTOR NOMINATIONS AND STOCKHOLDER PROPOSALS

     Our bylaws establish advance notice procedures for the nomination of
candidates for election as directors as well as for stockholder proposals to be
considered at annual meetings of stockholders. Notice of a stockholder's intent
to nominate a director must be received at our principal executive offices as
follows:

     - with respect to an election to be held at the annual meeting of
       stockholders, not later than 90 calendar days nor earlier than 120
       calendar days prior to the anniversary date of the immediately preceding
       annual meeting of stockholders; and


     - with respect to an election to be held at a special meeting of
       stockholders, not earlier than 120 calendar days before the special
       meeting nor later than the later of:


     (1) 90 calendar days prior to the special meeting or


     (2) 10 calendar days following the public announcement of the special
meeting.



     Notice of a stockholder's intent to raise business at an annual meeting
must be received at our principal executive offices not later than 90 calendar
days nor earlier than 120 calendar days prior to the anniversary date of the
preceding annual meeting of stockholders.



     These procedures may operate to limit the ability of stockholders to bring
business before a stockholders meeting, including the nomination of directors or
considering a transaction that could result in a change in control.


LIMITATION OF BUSINESS OPPORTUNITIES

     We have added provisions to our certificate of incorporation that limit the
scope of our business and provide that Duke Energy and its affiliates may engage
in the midstream gas gathering, processing, marketing and transportation
businesses, even if those businesses have a competitive impact on us. In
general, Duke Energy is permitted to engage in any business, including
businesses in competition with us, provided:

     - the business opportunity is not identified through the disclosure of
       information by or on behalf of our company or as a direct result of a
       person's service as an officer or director of our company; and

     - the business is developed and pursued solely through Duke Energy's own
       personnel and not through us.

                                       75
<PAGE>   77

     If an opportunity in the midstream natural gas gathering, processing,
marketing and transportation industry is presented to a person who is an officer
or director of both Duke Energy and our company, Duke Energy has no obligation
to communicate or offer the opportunity to us and may pursue the opportunity as
it sees fit, unless it was presented to that person solely in, and as a direct
result of, that person's service as a director or officer of our company.


     The purpose clause of our certificate of incorporation permits us to engage
only in the midstream natural gas gathering, processing, marketing and
transportation businesses in the United States and Canada, the marketing of NGLs
in Mexico and the transportation, marketing and storage of other petroleum
products. We may engage in other activities with the approval of eight of the
eleven members of our Board and, so long as Duke Energy owns, directly or
indirectly, a majority of our common stock or otherwise controls our company,
with the approval of Duke Energy in its sole discretion. We cannot amend our
certificate of incorporation to expand our purpose clause without Duke Energy's
prior written consent.


AMENDMENT OF THE BYLAWS


     Our certificate of incorporation and bylaws provide that the Board of
Directors may amend or repeal the bylaws and adopt new bylaws. Our bylaws
provide that the holders of common stock may amend or repeal the bylaws and
adopt new bylaws by a majority vote. However, so long as each of Duke Energy and
Phillips owns (directly or indirectly) at least 20% of our voting stock, any
amendment or repeal of, or adoption of any new bylaw inconsistent with, certain
of our bylaws relating to our Board of Directors (including supermajority
approval requirements) must be approved by each of Duke Energy and Phillips.


LIMITATION OF LIABILITY OF OFFICERS AND DIRECTORS


     Our certificate of incorporation provides that no director shall be
personally liable to our company or our stockholders for monetary damages for
breach of fiduciary duty as a director, except, if required by Delaware law, for
liability as follows:


     - for any breach of the director's duty of loyalty to our company or our
       stockholders;

     - for acts or omissions not in good faith or which involve intentional
       misconduct or a knowing violation of law;

     - for unlawful payment of a dividend or unlawful stock purchase or
       redemption; and

     - for any transaction from which the director derived an improper personal
       benefit.

     These provisions eliminate the rights of our company and our stockholders,
through stockholders' derivative suits on our behalf, to recover monetary
damages against a director for breach of fiduciary duty as a director, including
breaches resulting from grossly negligent behavior, except in the situations
described above.

DELAWARE ANTI-TAKEOVER STATUTE

     Under the terms of our certificate of incorporation and as permitted under
Delaware law, we have elected not to be governed by Delaware's anti-takeover
law. This law provides that specified persons who, together with affiliates and
associates, own, or within three years did own, 15% or more of the outstanding
voting stock of a corporation may not engage in certain business combinations
with the corporation for a period of three years after the date on which the
person became an interested stockholder. The law defines the term "business
combination" to encompass a wide variety of transactions with or caused by an
interested stockholder, including mergers, asset sales and other transactions in
which the interested stockholder receives or could receive a benefit on other
than a pro rata basis with other stockholders. With the approval of our
stockholders, we may amend our certificate of incorporation in the future to
become governed by the anti-takeover law. This provision would then have an
anti-takeover effect for transactions not approved in advance by our Board of
Directors, including discouraging takeover attempts that might result in a
premium over the market price for the shares of our common stock. By opting out
of the Delaware anti-takeover law, a transferee of Duke Energy or Phillips could
pursue a takeover transaction that was not approved by our Board of Directors.
                                       76
<PAGE>   78

SUPERMAJORITY REQUIREMENTS


     Our bylaws require the approval of at least eight of our eleven directors
for any of the following:


     - entering a new line of business outside of the midstream natural gas
       gathering, processing, marketing and transportation businesses (and
       directly related activities) in the United States and Canada;


     - any merger, consolidation, recapitalization, acquisition, divestiture,
       joint venture or alliance (or a related series of such transactions)
       involving the acquisition or expenditure (in the form of cash or
       otherwise) of more than $200 million in value to or from the company;


     - entering into any sales contract or commitment that has a term of five
       years or more and that involves annual revenues to the company of more
       than 5% of the company's total annual sales revenues for the most
       recently completed fiscal year;

     - any capital expenditure in excess of $200 million;

     - any borrowing in excess of $200 million;

     - approval of any shut-down of a facility having a fair market value of
       more than $100 million;

     - any liquidation or dissolution of the company;

     - changing auditors;

     - settlement of actions or claims against us involving payment by us of
       more than $25 million, excluding amounts covered or reimbursed by
       insurance;

     - entering into transactions with either Duke Energy, Phillips or any of
       their affiliates on terms that are clearly less favorable than those
       terms that are within the range of comparable transactions between
       unaffiliated third parties; and

     - approval of compensation policies for employees, including specific
       compensation and benefit plans and programs, to the extent such policies
       are of the type that would customarily be considered by a compensation
       committee of the board of directors of a comparably sized,
       publicly-traded corporation.

As long as each of Duke Energy and Phillips owns (directly or indirectly) at
least 20% of our voting stock, these provisions of the bylaws may not be amended
or changed without the consent of both Duke Energy and Phillips. The
requirements of super-majority approval for these actions will terminate when
the ownership interest of either Duke Energy or Phillips falls below 20%.

     Since the governance procedures described above require more than a
majority vote of the Board of Directors to approve a merger or consolidation,
this may make any merger or consolidation more difficult.


LISTING



     Our common stock has been approved for listing, subject to official notice
of issuance, on the New York Stock Exchange under the symbol "DEF."


TRANSFER AGENT AND REGISTRAR

     The Transfer Agent and Registrar for our common stock is Duke Energy.

                                       77
<PAGE>   79

                        SHARES ELIGIBLE FOR FUTURE SALE


     Prior to the offering, there was no public market for our common stock.
Future sales of substantial amounts of our common stock in the public market
could adversely affect the market price of our common stock. After the offering
is completed, the number of shares available for future sale into the public
markets will be subject to legal and contractual restrictions, some of which are
described below. The lapsing of these restrictions will permit sales of
substantial amounts of our common stock in the public market or could create the
perception that such sales could occur, which could adversely affect the market
price for our common stock. These factors could also make it more difficult for
us to raise funds through the future sale of common stock.



     Immediately after the offering, 140,752,211 shares of our common stock will
be outstanding. Of these shares, the 26,300,000 shares sold in the offering will
be freely transferable and may be sold without restriction or further
registration under the Securities Act, except for any shares acquired by our
"affiliates" as defined in Rule 144 under the Securities Act. The 114,341,711
shares of common stock outstanding and owned by Duke Energy and Phillips will be
subject to the lock-up agreements described below for 180 days after the date of
this prospectus after which they may be sold in the future without registration
under the Securities Act to the extent permitted by Rule 144, as described
below, or any applicable exemption under the Securities Act. In addition, shares
owned by Duke Energy and Phillips may be registered for sale under the
Securities Act under the terms of the registration rights agreement with us.


RULE 144

     Under Rule 144 beginning 90 days after the date of this prospectus, a
person, or persons whose shares are aggregated, who has beneficially owned
"restricted securities" for at least one year would be entitled to sell within
any three-month period a number of shares that does not exceed the greater of:


     - 1% of the number of shares of common stock then outstanding, which will
       equal approximately 1,407,500 shares immediately after the offering; and


     - the average weekly trading volume of the common stock on the New York
       Stock Exchange during the four calendar weeks preceding the filing of a
       notice on Form 144 with respect to such sale with the SEC.

Sales under Rule 144 are also subject to certain other requirements regarding
the manner of sale, notice and availability of current public information about
us.

     Under Rule 144(k), a person who is not deemed to have been one of our
"affiliates" at any time during the 90 days preceding a sale, and who has
beneficially owned the shares proposed to be sold for at least two years
(including the holding period of any prior owner other than an affiliate) is
entitled to sell such shares without complying with the manner of sale, public
information, volume limitation or notice provisions of Rule 144.

     Because Duke Energy and Phillips are among our affiliates, subject to
exercise of their registration rights described under "Relationship with Duke
Energy and Phillips -- Registration Rights Agreement," the Rule 144 restrictions
and requirements would be applicable to Duke Energy's and Phillips' shares for
as long as they retain affiliate status.

LOCK-UP AGREEMENTS


     In connection with the offering, we, Duke Energy and Phillips have agreed

       exchangeable or exercisable for common stock; or

     - enter into any swap or other arrangement that transfers to another, in
       whole or in part, any of the economic consequence of ownership of common

                MATERIAL UNITED STATES FEDERAL TAX CONSEQUENCES
                  TO NON-UNITED STATES HOLDERS OF COMMON STOCK

     The following is a general discussion of the material U.S. federal income
and estate tax considerations with respect to the ownership and disposition of
common stock applicable to Non-U.S. Holders. In general, a "Non-U.S. Holder" is
any beneficial owner of common stock other than

     - a citizen or resident of the United States,

     - a corporation, partnership or other entity created or organized in the
       United States or under the laws of the United States or of any state
       thereof,

     - an estate, the income of which is includible in gross income for U.S.
       federal income tax purposes regardless of its source, or

     - a trust whose administration is subject to the primary supervision of a
       United States court and which has one or more United States persons who
       have the authority to control all substantial decisions of the trust.

     This discussion is based on current provisions of the Internal Revenue
Code, Treasury Regulations promulgated under the Internal Revenue Code, judicial
opinions, published positions of the Internal Revenue Service, and all other
applicable authorities, all of which are subject to change, possibly with
retroactive effect. This discussion does not address all aspects of income and
estate taxation or any aspects of state, local, or non-U.S. taxes, nor does it
consider any specific facts or circumstances that may apply to a particular
Non-U.S. Holder that may be subject to special treatment under the U.S. federal
income tax laws, such as insurance companies, tax-exempt organizations,
financial institutions, brokers, dealers in securities, and U.S. expatriates.

     Prospective investors are urged to consult their tax advisors regarding the
U.S. federal, state, local and non-U.S. income and other tax considerations of
acquiring, holding and disposing of shares of common stock.

DIVIDENDS

     In general, dividends paid to a Non-U.S. Holder will be subject to U.S.
withholding tax at a 30% rate of the gross amount, or a lower rate prescribed by
an applicable income tax treaty, unless the dividends are effectively connected
with a trade or business carried on by the Non-U.S. Holder within the United
States. Dividends that are effectively connected with such a U.S. trade or
business generally will not be subject to U.S. withholding tax if the Non-U.S.
Holder files the required forms, including Internal Revenue Service Form 4224,
Form W-8ECI, or any successor form, with the payor of the dividend, and
generally will be subject to U.S. federal income tax on a net income basis, in
the same manner as if the Non-U.S. Holder were a resident of the United States.
An applicable treaty may also require the dividends to be attributable to a
permanent establishment in the United States to be subject to United States
taxes. A Non-U.S. Holder that is a corporation may be subject to an additional
branch profits tax at a rate of 30%, or such lower rate as may be specified by
an applicable income tax treaty, on the repatriation from the United States of
its "effectively connected earnings and profits," subject to adjustments. To
determine the applicability of a tax treaty providing for a lower rate of
withholding under the currently effective Treasury Regulations, dividends paid
to an address in a foreign country are presumed to be paid to a resident of that
country absent knowledge to the contrary. Under Treasury Regulations (the "Final
Regulations") generally effective for payments made after December 31, 2000,
however, a Non-U.S. Holder will be required to satisfy certification
requirements in order to claim a reduced rate of withholding under an applicable
income tax treaty. In addition, under the Final Regulations, in the case of
common stock held by a foreign partnership, the certification requirement would
generally be applied to the partners of the partnership (unless the partnership
agrees to become a "withholding foreign partnership") and the partnership would
be required to provide certain information. The Final Regulations also provide
"look-through" rules for tiered partnerships.

     A Non-U.S. Holder of common stock that is eligible for a reduced rate of
U.S. federal income tax withholding under a tax treaty may obtain a refund of
any excess amounts withheld by filing an appropriate claim for refund with the
Internal Revenue Service.

GAIN ON SALE OR OTHER DISPOSITION OF COMMON STOCK

     In general, a Non-U.S. Holder will not be subject to U.S. federal income
tax on any gain realized upon the sale or other taxable disposition of the
holder's shares of common stock so long as:

     - the gain is not effectively connected with a trade or business carried on
       by the Non-U.S. Holder within the United States;

     - if the Non-U.S. Holder is an individual, the Non-U.S. Holder holds shares
       of common stock as a capital asset, is not present in the United States
       for 183 days or more in the taxable year of disposition or does not have
       a "tax home" in the United States for U.S. federal income tax purposes
       and meets certain other requirements;

     - the Non-U.S. Holder is not subject to tax under the provisions of the
       Internal Revenue Code regarding the taxation of U.S. expatriates; and

     - the common stock continues to be "regularly traded on an established
       securities market" for U.S. federal income tax purposes and the Non-U.S.
       Holder has not held, directly or indirectly, at any time during the
       five-year period ending on the date of disposition (or, if shorter, the
       Non-U.S. Holder's holding period) more than five percent of the
       outstanding common stock.

ESTATE TAX

     Common stock owned or treated as owned by an individual who is not a
citizen or resident, as defined for U.S. federal estate tax purposes, of the
United States at the time of death will be includible in the individual's gross
estate for U.S. federal estate tax purposes, unless an applicable estate tax
treaty provided otherwise, and therefore may be subject to U.S. federal estate
tax.

                                       80

BACKUP WITHHOLDING, INFORMATION REPORTING AND OTHER REPORTING REQUIREMENTS

     We must report annually to the Internal Revenue Service and to each
Non-U.S. Holder the amount of dividends paid to, and the tax withheld with
respect to, each Non-U.S. Holder. These reporting requirements apply regardless
of whether withholding was reduced or eliminated by an applicable tax treaty.
Copies of this information also may be made available under the provisions of a
specific treaty or agreement with the tax authorities in the country in which
the Non-U.S. Holder resides or is established.

     Under current law, U.S. backup withholding tax (which generally is imposed
at the rate of 31% on applicable payments to persons that fail to furnish the
information required under the U.S. information reporting requirements) and
information reporting requirements generally will not apply to dividends paid on
common stock to a Non-U.S. Holder at an address outside the United States.
Backup withholding and information reporting generally will apply, however, to
dividends paid on shares of common stock to a Non-U.S. Holder at an address in
the United States if the holder fails to establish an exemption or to provide
certification of its non-U.S. status and other required information to the
payor.

     Under current law, the payments of proceeds from the disposition of common
stock to or through a U.S. office of a broker will be subject to information
reporting and backup withholding, unless the beneficial owner, under penalties
of perjury, certifies, among other things, its status as a Non-U.S. Holder or
otherwise establishes an exemption. The payment of proceeds from the disposition
of common stock to or through a non-U.S. office of a broker generally will not
be subject to backup withholding and information reporting, except as noted
below. In the case of proceeds from a disposition of common stock paid to or
through a non-U.S. office of a broker that is

     - a U.S. person,

     - a "controlled foreign corporation" for U.S. federal income tax purposes,
       or

     - a foreign person 50% or more of whose gross income from a specified
       period is effectively connected with a U.S. trade or business,

information reporting, but not backup withholding, will apply unless the broker
has documentary evidence in its files that the owner is a Non-U.S. Holder and
other conditions are satisfied, or the beneficial owner otherwise establishes an
exemption, and the broker has no actual knowledge to the contrary.

     Under the Final Regulations, the payment of dividends or the payment of
proceeds from the disposition of common stock to a Non-U.S. Holder may be
subject to information reporting and backup withholding unless the recipient
satisfies the certification requirements of the Final Regulations by proving its
non-U.S. status or otherwise establishes an exemption. Under the Final
Regulations, the sale of common stock outside of the U.S. through a non-U.S.
broker will also be subject to information reporting if the broker is a foreign
partnership and at any time during its tax year:

     - one or more of its partners are United States persons, as described in
       United States Treasury regulations, who in the aggregate hold more than
       50% of the income or capital interests in the partnership, or

     - the foreign partnership is engaged in a U.S. trade or business.

     Backup withholding is not an additional tax. Any amounts withheld under the
backup withholding rules from a payment to a Non-U.S. Holder can be refunded or
credited against the Non-U.S. Holder's U.S. federal income tax liability, if
any, provided that the required information is furnished to the Internal Revenue
Service in a timely manner.

     Each prospective Non-U.S. Holder of common stock should consult that
holder's own tax adviser with respect to the federal, state, local and foreign
tax consequences of the acquisition, ownership and disposition of common stock.

</TABLE>



     The underwriters are offering the shares of common stock subject to their
acceptance of the shares from Duke Energy Field Services Corporation and subject
to prior sale. The underwriting agreement provides that the obligations of the
several underwriters to pay for and accept delivery of the shares of common
stock offered by this prospectus are subject to the approval of certain legal
matters by their counsel and to certain other conditions. The underwriters are
obligated to take and pay for all of the shares of common stock offered by this
prospectus if any such shares are taken. However, the underwriters are not
required to take or pay for the shares covered by the underwriters'
over-allotment option described below.



     The per share price of any shares sold by the underwriters shall be the
public offering price listed on the cover page of this prospectus, in United
States dollars, less an amount not greater than the per share amount of the
concession to dealers described below.


     The underwriters initially propose to offer part of the shares of common
stock directly to the public at the public offering price listed on the cover
page of this prospectus and part to certain dealers at a price that represents a
concession not in excess of $     a share under the public offering price. Any
underwriter may allow, and such dealers may reallow, a concession not in excess
of $     a share to other underwriters or to certain dealers. After the initial
offering of the shares of common stock, the offering price and other selling
terms may from time to time be varied by the representatives.


     Duke Energy Field Services Corporation has granted to the underwriters an
option, exercisable for 30 calendar days from the date of this prospectus, to
purchase up to an aggregate of 3,945,000 additional shares of common stock at
the public offering price listed on the cover page of this prospectus, less
underwriting discounts and commissions. The underwriters may exercise this
option solely for the purpose of covering over-allotments, if any, made in
connection with the offering of the shares of common stock offered by this
prospectus. To the extent the option is exercised, each underwriter will become
obligated, subject to certain conditions, to purchase about the same percentage
of the additional shares of common stock as the number listed next to the
underwriter's name in the preceding table bears to the total number of shares of
common stock listed next to the names of all underwriters in the preceding
table. If the underwriters' option is exercised


                                       82
<PAGE>   84

in full, the total price to the public would be $635.1 million, the total
underwriters' discounts and commissions would be $33.3 million and proceeds to
Duke Energy Field Services Corporation would be $601.7 million.

     The underwriters have informed Duke Energy Field Services Corporation that
they do not intend sales to discretionary accounts to exceed five percent of the
total number of shares of common stock offered by them.


     Our common stock has been approved for listing, subject to official notice
of issuance, on the NYSE under the symbol "DEF."


     Each of Duke Energy Field Services Corporation and our directors, executive
officers and certain of our stockholders has agreed that, without the prior
written consent of Morgan Stanley & Co. Incorporated on behalf of the
underwriters, it will not, during the period ending 180 days after the date of
this prospectus:

     - offer, pledge, sell, contract to sell, sell any option or contract to
       purchase, purchase any option or contract to sell, grant any option,
       right or warrant to purchase, lend or otherwise transfer or dispose of
       directly or indirectly, any shares of common stock or any securities
       convertible into or exercisable or exchangeable for common stock; or

     - enter into any swap or other arrangement that transfers to another, in
       whole or in part, any of the economic consequences of ownership of the
       common stock.

whether any transaction described above is to be settled by delivery of common
stock or such other securities, in cash or otherwise.

The restrictions described in this paragraph do not apply to:

     - the sale of shares to the underwriters;

     - the issuance by Duke Energy Field Services Corporation of shares of
       common stock upon the exercise of an option or a warrant or the
       conversion of a security outstanding on the date of this prospectus of
       which the underwriters have been advised in writing; or

     - transactions by any person other than Duke Energy Field Services
       Corporation relating to shares of common stock or other securities
       acquired in open market transactions after the completion of the offering
       of the shares.

     In order to facilitate the offering of the common stock, the underwriters
may engage in transactions that stabilize, maintain or otherwise affect the
price of the common stock. Specifically, the underwriters may over-allot in
connection with the offering, creating a short position in the common stock for
their own account. In addition, to cover over-allotments or to stabilize the
price of the common stock, the underwriters may bid for, and purchase, shares of
common stock in the open market. Finally, the underwriting syndicate may reclaim
selling concessions allowed to an underwriter or a dealer for distributing the
common stock in the offering, if the syndicate repurchases previously
distributed common stock in transactions to cover syndicate short positions, in
stabilization transactions or otherwise. Any of these activities may stabilize
or maintain the market price of the common stock above independent market
levels. The underwriters are not required to engage in these activities, and may
end any of these activities at any time.

     From time to time, some of the underwriters have provided, and continue to
provide, investment banking services to Duke Energy Field Services Corporation,
Duke Energy, Phillips and their affiliates.


     Duke Energy Field Services Corporation and the underwriters have agreed to
indemnify each other against certain liabilities, including liabilities under
the Securities Act. The underwriters have agreed to reimburse Duke Energy Field
Services Corporation for certain of its expenses incurred in connection with the
offering in an amount not to exceed $     .



     At the request of Duke Energy Field Services Corporation, the underwriters
have reserved for sale, at the initial offering price, up to 1,972,500 shares
offered hereby for directors, officers, employees, business associates of Duke
Energy Field Service Corporation, and its two principal stockholders Duke Energy
and Phillips, and related persons. The shares of common stock available for sale
to the general public will be

                                       83
<PAGE>   85


reduced to the extent such persons purchase such reserved shares. Any reserved
shares which are not so purchased will be offered by the underwriters to the
general public on the same basis as the other shares offered hereby.



PRICING OF THE OFFERING



     Prior to the offering, there has been no public market for the common
stock. The initial public offering price will be determined through negotiations
between Duke Energy Field Services Corporation and the representatives. Among
the factors to be considered in determining the initial public offering price
will be the future prospects of Duke Energy Field Services Corporation and its
industry in general, sales, earnings and certain other financial operating
information of Duke Energy Field Services Corporation in recent periods, and the
price-earnings ratios, price-sales ratios, market prices of securities and
certain financial and operating information of companies engaged in activities
similar to those of the company. The estimated initial public offering price
range set forth on the cover page of this preliminary prospectus is subject to
change as a result of market conditions and other factors.


                          VALIDITY OF THE COMMON STOCK

     The validity of the shares of common stock we are offering will be passed
upon for us by Vinson & Elkins L.L.P., Houston, Texas and for the underwriters
by Sullivan & Cromwell, New York, New York.

                    UNAUDITED PRO FORMA FINANCIAL STATEMENTS


     The following unaudited pro forma financial statements (the "Unaudited Pro
Forma Financial Statements") of Duke Energy Field Services Corporation were
derived by the application of pro forma adjustments to historical combined and
consolidated financial statements included elsewhere in this prospectus. On
March 31, 2000, the Duke Energy and Phillips Petroleum midstream natural gas
businesses were contributed to Duke Energy Field Services LLC. Such contribution
included the general partner of TEPPCO as well as certain midstream natural gas
assets of Conoco, Inc. and Mitchell Energy & Development Corp. which were
acquired immediately prior to the Contribution. The contributions have been
reflected in the March 31, 2000 balance sheet of the Predecessor Company. The
Unaudited Pro Forma Balance Sheet gives effect to the subsequent borrowings,
distributions to Duke Energy and Phillips Petroleum, the public offering of
common stock in the Offering at an assumed initial public offering price of
$21.00 per share, elimination of minority interest and tax effects thereof
resulting from the merger of the holder of Phillips Petroleum's member interest
in Duke Energy Field Services LLC with the Company (the "Merger"), as if such
occurred on March 31, 2000. All of the events above are referred to collectively
as the "Transactions."


     The Unaudited Pro Forma Income Statements give effect to i) the
Transactions and ii) acquisition of the gas gathering business of Union Pacific
Resources (the "UP Fuels Acquisition"), which occurred March 31, 1999 as if such
transactions were consummated as of January 1, 1999.

     The adjustments are described in the accompanying Notes to the Unaudited
Pro Forma Balance Sheet and the Notes to the Unaudited Pro Forma Income
Statement. The Unaudited Pro Forma Financial Statements should not be considered
indicative of the actual results that would have been achieved had the
Transactions or the UP Fuels Acquisition been consummated on the dates or for
the period indicated and do not purport to indicate balances or results of
operations as of any future date or for any future period. The Unaudited Pro
Forma Financial Statements should be read in conjunction with the historical
combined and consolidated financial statements of the Predecessor Company, UP
Fuels, GPM and the notes thereto included elsewhere in this prospectus.

                     DUKE ENERGY FIELD SERVICES CORPORATION

                        NOTES TO THE UNAUDITED PRO FORMA
                                 BALANCE SHEET
                              AS OF MARCH 31, 2000

                                 (IN THOUSANDS)



     In December 1999, Duke Energy Field Services Corporation (the "Company")
and its subsidiary Duke Energy Field Services LLC ("Field Services LLC") were
formed to facilitate the combination of the midstream natural gas businesses of
Duke Energy and Phillips Petroleum Company (the "Combination"). The Company was
capitalized with 1,000 shares of common stock with a par value of $1.00 per
share.



     The Combination occurred on March 31, 2000. As part of the Combination
distributions of $1,524,519 and $1,219,800 payable to Duke Energy and Phillips,
respectively, have been recorded. In addition to contributing its midstream
natural gas business, Duke Energy contributed the General Partner of TEPPCO
Partners, L.P. a publicly traded limited partnership ("TEPPCO General Partner")
and the mid-continent midstream natural gas assets of Conoco, Inc. and Mitchell
Energy & Development Corp. acquired immediately prior to the Combination.
Subsequent to March 31, 2000 the Company borrowed $2,790,900 in commercial paper
(the "Indebtedness") and made the distributions discussed above. In connection
with the Offering, the Company acquired the Phillips member interests in Field
Services LLC in exchange for shares of the Company in the Merger.



     The Combination was accounted for as a purchase business combination in
accordance with Accounting Principles Board Opinion (APB) No. 16 "Accounting for
Business Combinations." The Predecessor Company was the acquiror of Phillips'
midstream natural gas business ("GPM") in the Combination.



     The following Notes to the Unaudited Pro Forma Balance Sheet describe the
adjustments to March 31, 2000 historical balances to give effect to borrowings,
the Offering and related transactions.


1. The pro forma financial data have been derived by the application of pro
   forma adjustments to the historical financial statements of the Company for
   the period noted. The sources and uses of funds are as follows:

   Commercial Paper program. On April 3, 2000 Field Services LLC borrowed
   $2,790,900 in the commercial paper market to fund distributions to Field
   Services LLC members and provide working capital. Commercial paper
   outstanding at April 30, 2000 has maturities ranging from one day to 70 days
   and had annual interest rates between 6.20% and $6.45%. The Credit Facility,
   matures on March 30 2001, bears interest at a rate equal to, at the Company's
   option, either (1) London Interbank Offered Rate (LIBOR) plus 0.50% per year
   for the first 90 days following the closing of the credit facility and LIBOR
   plus 0.625% per year thereafter or (2) the higher of (a) the Bank of America
   prime rate and (b) the Federal Funds rate plus 0.50% per year. Upon
   completion of the Offering, Field Services LLC's obligations under the
   facility will be assumed by Duke Energy Field Services Corporation and become
   an unsecured obligation.


   The Company plans to refinance a portion of the commercial paper with the
   proceeds of a term credit facility. Accordingly, pro forma interest expense
   has been calculated using Management's estimate of the weighted average rate
   at which the Company believes it will be able to refinance the commercial
   paper. Management believes that 8% is the appropriate interest rate for such
   an estimate. Such rate is higher than the prevailing commercial paper
   interest rate available as of the date of this filing.

               NOTES TO THE UNAUDITED PRO FORMA INCOME STATEMENTS
FOR THE YEAR ENDED DECEMBER 31, 1999 AND THE THREE MONTH PERIOD ENDED MARCH 31,
                                      2000
                                 (IN THOUSANDS)

     The Company's pro forma financial data have been derived by the application
of pro forma adjustments to the historical financial statements of the
Predecessor Company and other contributed businesses for the period noted. See
Note (1) to the Unaudited Pro Forma Balance Sheet.

1. Reflects the historical operating results of UP Fuels for the three month
   period ended March 31, 1999, the date the UP Fuels Acquisition was
   consummated by the Predecessor Company.

2. Reflects the results of operations associated with the acquisition of the
   Conoco and Mitchell businesses, net of the earnings from the
   Ferguson/Burleson Joint Venture interest exchanged as part of the
   consideration for the businesses.


3. Reflects equity earnings of the TEPPCO general partnership interest
   contributed by Duke Energy.


4. The pro forma adjustments exclude non-recurring expenses directly related to
   the Transactions which the Company anticipates will be reflected in the
   income statement for the period including the Transactions. Such expenses
   relate principally to the write-off of existing deferred financing fees on
   debt repaid as described in Note (3) to the Unaudited Pro Forma Balance
   Sheet.

5. The excess purchase cost over the book value of net GPM assets acquired in
   the Combination has not yet been fully allocated to individual assets and
   liabilities acquired. However, the Company believes a portion will be
   allocated to property, plant and equipment and identifiable intangibles and
   the remainder, representing goodwill, will be amortized over 20 years. Given
   its preliminary estimate of the allocation of the purchase cost to net assets
   acquired, management has estimated a composite life of 20 years.

     The adjustment to depreciation and amortization was calculated as follows:

would change pro forma interest expense with respect to the Indebtedness by
$2,673 after paydown with the proceeds of the Offering. Pro forma net income
would change by $1,657 on an annual basis.

   federal and state statutory income tax of 38% on pro forma taxable income,
   which is adjusted for the increase in non-deductible goodwill amortization as

                          INDEPENDENT AUDITORS' REPORT

Duke Energy Field Services Corporation and Affiliates

     We have audited the accompanying combined balance sheets of Duke Energy
Field Services Corporation and Affiliates ("the Predecessor Companies") as of
December 31, 1998 and 1999, and the related combined statements of income and
stockholders' equity and cash flows for each of the three years in the period
ended December 31, 1999. The Predecessor Companies are under common ownership
and common management. These financial statements are the responsibility of the
Predecessor Companies' management. Our responsibility is to express an opinion
on these financial statements 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, such financial statements present fairly, in all material
respects, the combined financial position of the Predecessor Companies as of
December 31, 1998 and 1999, and the combined results of their operations and
their combined cash flows for each of the three years in the period ended
December 31, 1999 in conformity with generally accepted accounting principles.

             DUKE ENERGY FIELD SERVICES CORPORATION AND AFFILIATES

                     NOTES TO COMBINED FINANCIAL STATEMENTS
                  YEARS ENDED DECEMBER 31, 1997, 1998 AND 1999

1. ACCOUNTING POLICIES SUMMARY


     Principles of Combining -- The accounting policies are presented to assist
the reader in evaluating the combined financial statements of Duke Energy Field
Services Corporation (the Company), Duke Energy Field Services, Inc. (DEFSI),
Panhandle Field Services Company (PFSC), Panhandle Gathering Company (PGC), and
Duke Energy Services Canada, Ltd. (DESCL) (together, "Duke Energy Field Services
Corporation and Affiliates" or the Predecessor Companies). The Predecessor
Companies are indirect subsidiaries of Duke Energy Corporation (Duke Energy).
During 1999, PFSC and PGC were contributed to and became wholly-owned
subsidiaries of DEFSI. The resulting December 31, 1999 stockholders' equity
(1,000 shares authorized and issued, $1.00 par value) reflects that of the
Company and DESCL. Our certificate of incorporation limits the scope of our
business to the midstream natural gas industry in the United States and Canada
and the marketing of natural gas liquids in Mexico.



     The Combination -- On December 16, 1999, Duke Energy and Phillips Petroleum
Company
(Phillips) entered into an agreement to combine their United States and Canadian
midstream natural gas gathering, processing and natural gas liquid operations
(the Combination). In connection with the Combination, Duke Energy's midstream
natural gas gathering and processing business was transferred to Duke Energy
Field Services LLC (Field Services LLC) and the Combination will be accounted
for as an acquisition by the Predecessor Companies of Phillips' midstream
business.


     Use of Estimates -- The preparation of financial statements in conformity
with generally accepted accounting principles requires management to make
estimates and assumptions that affect the 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. Actual results could differ from those estimates.

     Cash and Cash Equivalents -- All liquid investments with maturities at date
of purchase of three months or less are considered cash equivalents.

     Inventories -- Inventories are recorded at the lower of cost or market
using the average cost method.

     Property, Plant and Equipment -- Property, plant and equipment are stated
at cost, which does not purport to represent replacement or realizable value.
Assets, including goodwill and other intangibles, are evaluated for potential
impairment based on undiscounted cash flows and any impairment recorded is
derived based on discounted cash flows. There was no impairment during 1997,
1998 or 1999. Depreciation of property, plant and equipment is computed using
the straight-line method (see Note 4).

     Interest totaling $2.3 million, $1.6 million and $.9 million has been
capitalized on construction projects for 1997, 1998 and 1999, respectively.

     Revenue Recognition -- The Predecessor Companies recognize revenues on
sales of natural gas and petroleum products in the period of delivery and
transportation revenues in the period service is provided. An allowance for
doubtful accounts is established based on agings of accounts receivable and the
credit worthiness of our customers. Bad debt expense and writeoffs for each year
presented are not significant. A reserve of $3 million was established in
connection with the UP Fuels acquisition (see Note 2) over that recorded by UP
Fuels. This amount represents the Predecessor Companies' assessment of the
unrecoverable portion of receivables acquired from UP Fuels.

     Equity in Unconsolidated Affiliates -- Investments in 20% to 50% owned
affiliates are accounted for using the equity method. Investments greater than
50% are consolidated unless the Predecessor Companies do not operate these
investments and as a result do not have the ability to exercise control or
control is considered to be temporary.

            YEARS ENDED DECEMBER 31, 1997, 1998 AND 1999--CONTINUED

     Derivative Contracts -- The Predecessor Companies use commodity swaps,
futures and option contracts in the conduct of their business. Unrealized gains
and losses associated with activity other than trading are recognized when the
underlying physical transaction is recorded. Trading activity is
marked-to-market and reflected in the statements of income as sales of natural
gas and petroleum products or costs of such.

     Significant Customers -- Duke Energy Trading and Marketing, L.L.C. (DETM),
an affiliated company, is a significant customer. Sales to DETM totaled $567
million, $522 million and $684 million during 1997, 1998 and 1999, respectively.

     Intangibles Amortization -- Goodwill is amortized over the period of
expected benefit. Goodwill is being amortized on a straight-line basis over 15
years related to the 1991 acquisition of MEGA Natural Gas Company and 20 years
related to the UP Fuels acquisition (see Note 2). Natural gas liquids sales
contracts are amortized on a straight-line basis over the contract lives which
average 15 years.

     Environmental Costs -- Environmental expenditures are expensed or
capitalized as appropriate, depending upon the future economic benefit.
Expenditures that relate to an existing condition caused by past operations, and
that do not have future benefit, are expensed. Liabilities for these
expenditures are recorded on an undiscounted basis when environmental
assessments or clean-ups are probable and the costs can be reasonably estimated.
Environmental liabilities at the end of 1998 and 1999 were insignificant.

     Gas Imbalance Accounting -- Quantities of natural gas over-delivered or
under-delivered related to imbalance agreements are recorded monthly as
receivables or payables using index prices or the weighted average prices of
natural gas at the plant or system. Generally, these balances are settled with
deliveries of natural gas.

     Deferred Income Tax -- The Predecessor Companies follow the asset and
liability method of accounting for income tax. Deferred taxes are provided for
temporary differences in the tax and financial reporting basis of assets and
liabilities. The effect of a change in tax rates on deferred tax assets and
liabilities is recognized in income in the period the rate change is enacted.

     Stock Based Compensation -- The Predecessor Companies account for
stock-based compensation using the intrinsic method of accounting. Under this
method, compensation cost, if any, is measured as the excess of the quoted
market price of stock at the date of the grant over the amount an employee must
pay to acquire stock. Restricted stock is recorded as compensation cost over the
requisite vesting period based on the market value on the date of the grant.

     Earnings Per Share -- The historical capital structure of the Predecessor
Companies is not representative of the future capital structure of DEFSI (see
Note 2), as all companies were wholly-owned subsidiaries. Accordingly, the
historical net income per share and weighted average number of common shares
outstanding are not shown for any of the periods presented.

     Comprehensive Income -- The Predecessor Companies' only item of other
comprehensive income is foreign currency translation.

     Recently Issued Accounting Pronouncements -- In June 1998, the Financial
Accounting Standards Board issued Statement of Financial Accounting Standards
No. 133, "Accounting for Derivative Instruments and Hedging Activities" (SFAS
133). SFAS 133 establishes standards for derivative instruments, including
certain derivative instruments embedded in other contracts (collectively
referred to as derivatives) and for hedging activities. SFAS 133 requires that
an entity recognize all derivatives as either assets or liabilities in the
statement of financial position and measure those instruments at fair value. If
certain conditions are met, a derivative may be specifically designated as (a) a
hedge of the exposure to changes in the fair value of a recognized asset or
liability or an unrecognized firm commitment, (b) a hedge of the exposure to
variable cash flows of a forecasted transaction, or (c) a hedge of the foreign
currency exposure of a net investment in a

foreign operation, an unrecognized firm commitment, an available-for-sale
security, or a foreign-currency-denominated forecasted transaction. The
accounting for changes in the fair value of a derivative (gains and losses)
depends on the intended use of the derivative and the resulting designation. The
Predecessor Companies are required to adopt SFAS 133 on January 1, 2001. The
Predecessor Companies have not completed the process of evaluating the impact
that will result from adopting SFAS 133.

2. BUSINESS COMBINATIONS/DISPOSITIONS

     In March 1998, the Predecessor Companies sold a fractionator to TEPPCO
Colorado, L.L.C., an indirect, wholly-owned subsidiary of TEPPCO Partners, L.P.
(TEPPCO), of which Duke Energy, through an indirect, wholly-owned subsidiary,
has an equity interest of approximately 18%. The fractionator was sold for $40
million and the Predecessor Companies realized a gain of approximately $38
million.

     On March 31, 1999, the Predecessor Companies acquired the assets and
assumed certain liabilities of Union Pacific Fuels, Inc. (UP Fuels), a
wholly-owned subsidiary of Union Pacific Resources Company (UPR), for a total
purchase price of $1.359 billion. The acquisition was accounted for under the
purchase method of accounting, and the assets and liabilities and results of
operations of UP Fuels have been consolidated in the Predecessor Companies'
financial statements since the date of purchase. The purchase price has been
allocated to the assets acquired and liabilities assumed based on estimated fair
value, as follows:

     The gas marketing component of UP Fuels was immediately transferred to an
affiliate of Duke Energy after the acquisition at the above fair value. Revenues
and net income for 1998 on a pro forma basis would have increased $1.4 billion
and $54.9 million, respectively, if the acquisition had occurred on January 1,
1998. Revenues and net income for 1999 on a pro forma basis would have increased
$298 million and $2.8 million, respectively, if the acquisition had occurred on
January 1, 1999.

</TABLE>

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

     (1) Operating, general and administrative expenses are allocated to
         affiliates based on cost.


     As of December 31, 1998 and 1999, the Predecessor Companies had a $101.6
million note payable to Duke Energy, scheduled to mature in 2004 bearing
interest at 8.5%. Additionally, as of December 31, 1999, the Predecessor
Companies had a $540 million note payable to Duke Energy, scheduled to mature
December 31, 2000 bearing interest at prime (8.5% at December 31, 1999),
adjusted quarterly, and a $44.3 million and $4.6 million note payable to Duke
Energy, payable on demand and bearing interest at the Canadian Prime Rate (6.5%
at December 31, 1999), plus fifty basis points, adjusted quarterly.



     Intercompany advances do not bear interest. Advances are carried as open
accounts and are not segregated between current and non-current amounts.
Increases and decreases in advances result from the movement of funds to provide
for operations, capital expenditures, and debt payments of Duke Energy and its
subsidiaries. In addition, current income tax balances are recorded in these
accounts. Average intercompany advances payable approximated $117.3 million,
$203.8 million and $1,410 million for 1997, 1998 and 1999, respectively.



     Duke Energy supplies the Predecessor Companies with various staff and
support services, including information technology products and services,
payroll, employee benefits, corporate insurance, cash manage-

ment, ad valorem taxes, treasury and legal functions. These expenditures are
allocated to the Predecessor Companies using a cost based method of allocation.
Management believes the allocation is reasonable and estimates that such costs
approximate the costs for such services that would have been incurred on a stand
alone basis.


     See Notes 5 and 12 for discussion of other specific transactions with
affiliates.

7. INCOME TAXES

     The Predecessor Companies' taxable income is included in a consolidated
federal income tax return with Duke Energy. Therefore, income tax has been
provided in accordance with Duke Energy's tax allocation policy, which requires
subsidiaries to calculate federal income tax as if separate taxable income, as
defined, was reported. Foreign income taxes are not material and therefore are
not shown separately.

     Income tax as presented in the combined statements of income is summarized
as follows:

8. BUSINESS SEGMENTS AND RELATED INFORMATION

     The Predecessor Companies operate in two principal business segments as
follows: (1) natural gas gathering, processing, transportation, marketing and
storage, and (2) natural gas liquids fractionation, transportation, marketing
and trading. These segments are separately monitored by management for
performance against its internal forecast and are consistent with the
Predecessor Companies internal financial reporting package. These segments have
been identified based upon the differing products and services, regulatory
environment and the expertise required for these operations. Margin, earnings
before interest, taxes, depreciation and amortization (EBITDA) and earnings
before interest and taxes (EBIT) are the performance measures utilized by
management to monitor the business of each segment. The accounting policies for
the segments are the same as those described in Note 1. Foreign operations are
not material and are therefore not separately identified.

     The following table sets forth the Predecessor Companies' segment
information as of and for the years ended December 31, 1997, 1998 and 1999.

9. RISK MANAGEMENT AND FINANCIAL INSTRUMENTS


     The Predecessor Companies' operations are subject to the volatility of
commodity prices, particularly that of NGL prices. The Predecessor Companies
manage exposure to risk from existing contractual commitments through forward
contracts, futures and over-the-counter swap agreements (collectively,
"commodity instruments"). Energy commodity forward contracts involve physical
delivery of an energy commodity. Energy commodity futures involve the buying or
selling of natural gas, crude oil (used to hedge NGLs prices) and NGLs at a
fixed price. Over-the-counter swap agreements require the Predecessor Companies
to receive or make payments based on the difference between a specified price
and the actual price of the underlying commodity.



     Commodity Instruments -- Trading -- The Predecessor Companies, through a
wholly-owned subsidiary, engage in the trading of NGLs and crude oil commodity
instruments, and therefore experience net open positions. The Predecessor
Companies manage open positions with policies which limit its exposure to market
risk and require daily reporting to management of potential financial exposure.
The weighted-average life of the Predecessor Companies commodity risk portfolio
was approximately 2 months at December 31, 1999. During 1999 net gains of $9.7
million were recognized from trading NGLs and crude oil derivatives. The
Predecessor Companies were not trading NGLs nor crude oil commodity instruments
prior to 1999. As of December 31, 1999, the absolute notional contract quantity
of NGLs and crude oil commodity derivatives held for trading purposes was
5,826,000 and 6,486,500 barrels, respectively.

</TABLE>


     Commodity Derivatives -- Non-Trading -- At December 31, 1998 and 1999, the
Predecessor Companies held or issued derivatives that reduce the Predecessor
Companies' exposure to market fluctuations in the price and transportation costs
of natural gas and NGLs. The Predecessor Companies' market exposure arises from
inventory balances and fixed-price purchase and sale commitments that extend for
periods of up to 10 years. Futures and swaps are used to manage and hedge prices
and location risk related to these market exposures. Futures and swaps are also
used to manage margins on offsetting fixed-price purchase or sale commitments
for physical quantities of natural gas and NGLs.



     The gains, losses and costs related to those commodity derivatives that
qualify as a hedge are not recognized until the underlying physical transaction
occurs. At December 31, 1998 and 1999, the Predecessor Companies unrealized net
gains (losses) related to commodity derivative hedges was $1.8 million and
$(63.5) million, respectively. As of December 31, 1998 and 1999, the absolute
notional contract quantity of commodity derivatives held for non-trading
purposes was 10.92 and 7.8 billion cubic feet (Bcf) of natural gas and 59,000
and 32,764,000 barrels of crude oil, respectively. Hedging losses in 1999
totaled approximately $34 million.

     Market and Credit Risk -- Most futures and swaps are conducted through
either DETM or Duke Energy Merchants (DEM). Under these arrangements the
Predecessor Companies do not have margin requirements.

     New York Mercantile Exchange (Exchange) traded futures contracts are
guaranteed by the Exchange and have nominal credit risk. On all other
transactions previously described, the Predecessor Companies are exposed to
credit risk in the event of nonperformance by the counterparties. For each
counterparty, the Predecessor Companies analyze the financial condition prior to
entering into an agreement. The change in market value of exchange-traded
futures contracts other than those conducted through either DETM or DEM require
daily cash settlement in margin accounts with brokers. Swap contracts are
generally settled at the expiration of the contract term and may be subject to
margin requirements with the counterparty.

     Gathering, processing, and transportation services are provided to
producers, refiners, and a variety of wholesale and retail customers located in
the Mid-Continent, Gulf Coast and Rocky Mountain areas as well as in Canada. The
principal markets for natural gas marketing services are industrial end-users
and utilities located throughout the United States. The Predecessor Companies
have a concentration of receivables due from gas and electric utilities and
their affiliates, as well as industrial customers throughout the United States.
These concentrations of customers may affect the Predecessor Companies' overall
credit risk in that certain customers may be similarly affected by changes in
economic, regulatory or other factors. Trade receivables are generally not
collateralized; however, the Predecessor Companies analyze customers' financial
condition prior to extending credit, establish credit limits and monitor the
appropriateness of these limits on an ongoing basis.

10. ESTIMATED FAIR VALUE OF FINANCIAL INSTRUMENTS

     The following disclosure of the estimated fair value of financial
instruments is made in accordance with the requirements of SFAS No. 107,
"Disclosures about Fair Value of Financial Instruments." The estimated fair
value amounts have been determined by the Predecessor Companies, using available
market information and appropriate valuation methodologies. However,
considerable judgment is necessarily required in interpreting market data to
develop the estimates of fair value. Accordingly, the estimates presented herein
are not necessarily indicative of the amounts that the Predecessor Companies
could realize in a current market exchange. The use of different market
assumptions and/or estimation methodologies may have a material effect on the
estimated fair value amounts.

     Notes receivable is carried in the accompanying balance sheet at cost. Fair
value has been estimated using discounted cash flows assuming current interest
rates, similar credit risk and maturities.

     Related party advances and notes payable are carried at cost. Fair value
has been estimated using discounted cash flows of maturities of five years and
interest rates of 8.0%.

     The estimated fair value of the natural gas, NGL and oil hedge contracts is
determined by multiplying the difference between the quoted termination prices
for natural gas, NGL and oil and the hedge contract prices by the quantities
under contract.

11. COMMITMENTS AND CONTINGENT LIABILITIES

     The midstream natural gas industry has seen an increase in the number of
class action lawsuits involving royalty disputes, mismeasurement and mispayment
allegations. Although the industry has seen these types of cases before, they
were typically brought by a single plaintiff or small group of plaintiffs. Many
of these cases are now being brought as class actions. The Predecessor Companies
are currently named as defendants in certain of these cases. Management believes
the Predecessor Companies have meritorious defenses to these cases, and
therefore will continue to defend them vigorously. However, these class actions
can be costly and time consuming to defend.

     The Predecessor Companies are subject to federal, state and local
regulations regarding air and water quality, hazardous and solid waste disposal
as well as other environmental matters. The Predecessor Companies are not aware
of any material violations and have accrued for the known remediation that is in
process. In connection with the UP Fuels acquisition, the Company analyzed water
and soil samples surrounding UP Fuels facilities and identified necessary
remedial actions. The Company transferred this obligation to a third party for a
payment of approximately $48 million. Generally, environmental liabilities are
not expected to be recoverable from insurance or other third parties.

     The Predecessor Companies utilize assets under operating leases in several
areas of operation. Combined rental expense amounted to $8.1 million, $8.2

     There were 29,646 and 82,050 options exercisable at December 31, 1997 and
1998 with a weighted average exercise price of $21 and $22 per option.

     No compensation cost related to the stock options has been recorded as the
intrinsic method of accounting is used and the exercise price of each option
granted equaled the market price on the date of grant. The weighted average fair
value of options granted was $10.00, $9.00 and $10.00 per option during 1997,
1998 and 1999, respectively. The fair value of each option granted was estimated
on the date of grant using the Black-Scholes option-pricing model. The
weighted-average assumptions for option-pricing in 1997, 1998 and

1999 were: stock dividend yield of 3.5%, 4.2% and 4.1%, expected stock price
volatility of 20.7%, 15.1% and 18.8% and risk-free interest rates of 6.5%, 5.6%
and 5.9%, respectively. The expected option life for 1997, 1998 and 1999 was
seven years. Stock-based compensation expense calculated using the Black-Scholes
option-pricing model for 1997, 1998 and 1999 would have been $0.1 million, $0.8
million and $2.5 million, respectively and net income would have been $51.1
million, $1.5 million and $41.8 million, respectively.


     In addition, Duke Energy granted restricted shares of Duke Energy common
stock to key employees of the Predecessor Companies under Duke Energy stock
incentive plans. Grants under the plans vest over periods ranging from one to
seven years. In 1997 and 1999 Duke Energy awarded 2,817 shares (fair value at
grant dates of approximately $168,000) and 36,300 shares (fair value at grant
dates of approximately $2 million) to key employees of the Predecessor
Companies. No restricted shares were awarded in 1998. Compensation expense for
the stock grants is charged to the earnings of the Predecessor Companies over
the vesting period, and amounted to approximately $168,000, $0 and $488,000 in
1997, 1998 and 1999, respectively.


     Duke Energy has, and the Predecessor Companies' participate in, a
non-contributory trustee pension plan which covers eligible employees with a
minimum of one year vesting service. The plan provides pension benefits for
eligible employees of the Predecessor Companies that are generally based on the
employee's actual eligible earnings and accrued interest. Through December 31,
1998, for certain eligible employees, a portion of their benefit may also be
based on the employee's years of benefit accrual service and highest average
eligible earnings. Effective January 1, 1999, the benefit formula under the plan
for all eligible employees was changed to a cash balance formula. Duke Energy's
policy is to fund amounts, as necessary, on an actuarial basis to provide assets
sufficient to meet benefits to be paid to plan members. Aspects of the plan
specific to the Predecessor Companies is as follows:

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                 MARCH 31, 2000
                                  (UNAUDITED)

1. GENERAL


     Duke Energy Field Services Corporation (collectively with its consolidated
subsidiaries, the Company) operates in the midstream natural gas gathering,
marketing and natural gas liquids industry. The Company is an indirect,
wholly-owned subsidiary of Duke Energy Corporation (Duke Energy). The Company
operates in the two principal segments of the midstream natural gas industry of
(1) natural gas gathering, processing, transportation, marketing and storage;
and (2) natural gas liquids (NGLs) fractionation, transportation, marketing and
trading.



     The interim consolidated financial statements presented herein should be
read in conjunction with the combined financial statements and notes thereto of
Duke Energy Field Services Corporation and Affiliates. In the opinion of
management, all adjustments necessary for a fair presentation of the results for
the unaudited interim periods have been made. Except as explicitly noted, these
adjustments consist solely of normal recurring accruals.


2. COMBINATION


     On March 31, 2000, the natural gas gathering, processing and natural gas
liquid assets, operations, and subsidiaries of Duke Energy were contributed to
Duke Energy Field Services, LLC (Field Services LLC). In connection with the
contribution of assets and subsidiaries at March 31, 2000, notes and advances
payable to Duke Energy were eliminated and contributed to stockholders' equity.
Also on March 31, 2000, Phillips Petroleum Company (Phillips) contributed its
midstream natural gas gathering, processing and natural gas liquid operations to
Field Services LLC. This contribution and Duke Energy's contribution to Field
Services LLC are referred to as "the Combination." In exchange for the
contributions, the Company received 69.7% of the member interests in Field
Services LLC, with Phillips holding the remaining 30.3% of the outstanding
member interests.


     The Combination has been accounted for as a purchase business combination
in accordance with Accounting Principles Board Opinion (APB) No. 16 "Accounting
for Business Combinations". The Phillips assets, net of liabilities, have been
valued at $1,919.8 million. Goodwill of $412.9 million has been recorded
preliminarily for the deferred tax effect of the purchase price allocated to
property, plant and equipment being above the existing tax basis and will be
amortized on a straight-line basis over 20 years. Following is a summary of the
preliminary allocation of purchase price (in millions):

                                  (UNAUDITED)

each of Duke Energy and Phillips will have contributed to Field Services LLC net
working capital positions equal to zero as of March 31, 2000.

     Pro Forma Disclosures: Revenues for the three months ended March 31, 1999
and 2000, on a pro forma basis would have increased $264.9 million and $542.4
million, respectively, and net income for the three months ended March 31, 1999
and 2000, on a pro forma basis would have decreased $8.2 million and increased
$17.0, respectively, if the acquisition of the Phillips midstream business had
occurred at the beginning of the period presented.

     TEPPCO General Partner Interest -- On March 31, 2000, and in connection
with the Combination, Duke Energy contributed the general partner interest of
TEPPCO Partners L.P. to Field Services LLC. In connection with the contribution
of the general partner interest in TEPPCO, the Company recorded an investment in
TEPPCO of $2.3 million, recorded $39.2 million in non-current deferred tax
liability, and reduced stockholders' equity by $36.9 million.

     TEPPCO is a publicly traded limited partnership that owns and operates a
network of pipelines for refined products and crude oil. The general partner is
responsible for the management and operations of TEPPCO. Through the ownership
of the general partner of TEPPCO, Field Services LLC has the right to receive
from TEPPCO incentive cash distributions in addition to a 2% share of
distributions based on the general partner interest. At TEPPCO's 1999 per unit
distribution level, the general partner received approximately 14% of the cash
distributed by TEPPCO to its partners. Due to the general partner's share of
unit distributions and control exercised through its management of the
partnership, the Company's investment in TEPPCO is accounted for under the
equity method.

3. ACQUISITIONS

     Union Pacific Fuels, Inc. -- On March 31, 1999, the Company acquired the
assets and assumed certain liabilities of Union Pacific Fuels, Inc. (UP Fuels),
a wholly-owned subsidiary of Union Pacific Resources Corporation, for a total
purchase price of $1,359 million. The acquisition was accounted for under the
purchase method of accounting, and the assets and liabilities and results of
operations of UP Fuels have been consolidated in the Company's financial
statements since the date of purchase. Revenues and net income for the three
months ended March 31, 1999 on a pro forma basis would have increased $298
million and $3.4 million respectively, if the acquisition of UP Fuels had
occurred on January 1, 1999.

     Conoco and Mitchell Assets -- On March 31, 2000, Field Services LLC (funded
by Duke Energy) acquired gathering and processing facilities located in central
Oklahoma from Conoco, Inc. and Mitchell Energy & Development Corp. Field
Services LLC paid cash of $99.5 million, and exchanged its interests in certain
gathering and marketing joint ventures located in southeast Texas having a total
net book value of $42.0 million as consideration for these facilities.

4. AGREEMENTS AND TRANSACTIONS WITH DUKE ENERGY

     Services Agreement with Duke Energy -- Effective with the Combination, the

business. The Company anticipates continuing these transactions in the ordinary
course of business.

5. AGREEMENTS AND TRANSACTIONS WITH PHILLIPS

     Services Agreement with Phillips -- Effective with the Combination, the
Company entered into a services agreement with Phillips ("the Phillips Services
Agreement"). Under the Phillips Services Agreement, Phillips will provide the
Company with various staff and support services, including information
technology products and services, cash management, real estate and property tax
services. These services will be priced on a basis of a monthly charge equal to
Phillips' fully-burdened cost of providing the services. The Phillips Services
Agreement expires on December 31, 2000.


     Long-Term NGLs Purchases Contract with Phillips -- In connection with the
Combination, the Company has agreed to maintain the NGL Output Purchase and Sale
Agreement ("Phillips NGL Agreement") between Phillips and the midstream natural
gas assets that were contributed by Phillips to the Company in the Combination.
Under the Phillips NGL Agreement, Phillips 66 Company, a wholly-owned subsidiary
of Phillips, has the right to purchase at index-based prices approximately all
NGLs produced by the processing plants which were acquired by Field Services LLC
from Phillips in the Combination. The Phillips NGL Agreement also grants
Phillips 66 Company the right to purchase at index-based prices certain
quantities of NGLs produced at processing plants that are acquired and/or
constructed by the Company in the future in various counties in the
Mid-Continent and Permian Basis regions, and the Austin Chalk area. The primary
term of the agreement is effective until December 31, 2014.



     Transactions between Phillips and the Midstream Business Acquired from
Phillips -- Through March 31, 2000, the Phillips' businesses (the "Phillips
Combined Subsidiaries") that owned the midstream natural gas assets that were
contributed to the Company in the Combination had conducted a series of
transactions with Phillips in which the Phillips Combined Subsidiaries sold a
portion of their residue gas and other by-products to Phillips at contractual
prices that approximated market prices. In addition, Phillips Combined
Subsidiaries purchased raw natural gas from Phillips at contractual prices that
have approximated market prices. The Company anticipates continuing these
transactions in the ordinary course of business.


6. FINANCING

     Credit Facility with Financial Institutions -- In March 2000, Field
Services LLC entered into a $2,800 million credit facility with several
financial institutions. The credit facility will be used to support a commercial
paper program for short-term financing requirements. On April 3, 2000, Field
Services LLC borrowed $2,790.9 million in the commercial paper market to fund
one-time cash distributions of $1,524.5 million to Duke Energy, and $1,219.8
million to Phillips on such date and to meet working capital requirements. The
credit facility matures on March 30, 2001, and bears interest at a rate equal
to, at Field Services LLC's option, either (1) the London Interbank Offered Rate
(LIBOR) plus .50% per year for the first 90 days following March 31, 2000 and
LIBOR plus .625% per year thereafter, or (2) the higher of (a) the Bank of
America prime rate and (b) the Federal Funds rate plus .50% per year.


     Revolving Credit Agreement -- Effective April 4, 2000, Field Services LLC
entered into a $100 million revolving credit agreement with Duke Capital
Corporation, an indirect, wholly-owned subsidiary of Duke Energy. The revolving

7. RISK MANAGEMENT AND FINANCIAL INSTRUMENTS

     Historically, the Company's commodity price risk management program had
been directed by Duke Energy under its centralized program for controlling,
managing and coordinating its management of risks. During the three months ended
March 31, 1999 and 2000, the Company recorded a hedging gain of $4.0 million and
a hedging loss of $46.7 million, respectively, under Duke Energy's centralized
program. As of March 31, 2000, the existing commodity positions held under the
Duke Energy centralized program were transferred to Duke Energy.

     Effective April 1, 2000, the Company began directing its risk management
activities, including commodity price risk for market fluctuations in the price
of NGLs, independently of Duke Energy. The Company plans to use commodity-based
derivative contracts to reduce the risk in the Company's overall earnings and
cash flow with the primary goals of: (1) maintaining minimum cash flow to fund
debt service, dividends and maintenance type capital projects; (2) avoiding
disruption of the Company's growth capital and value creation process; and (3)
retaining a high percentage of the potential upside relation to commodity price
increases. The Company has implemented a risk management policy that provides
guidelines for entering into contractual arrangements to manage commodity price
exposure. Futures and swaps will be used to manage and hedge prices related to
these market exposures.

     In establishing its initial independent commodity risk management position,
on April 1, 2000 the Company acquired a portion of Duke Energy's existing
commodity derivatives held for non trading purposes. The absolute notional
contract quantity of the positions acquired was 4,607,000 barrels of crude oil.
Such positions were acquired at market value.

8. COMMITMENTS AND CONTINGENT LIABILITIES

     The midstream natural gas industry has seen an increase in the number of
class action lawsuits involving royalty disputes, mismeasurement and mispayment
allegations. Although the industry has seen these types of cases before, they
were typically brought by a single plaintiff or small group of plaintiffs. Many
of these cases are now being brought as class actions. The Company and its
subsidiaries are currently named as defendants in certain of these cases.
Management believes the Company and its subsidiaries have meritorious defenses
to these cases, and therefore will continue to defend them vigorously. However,
these class actions can be costly and time consuming to defend.

9. PENSION AND OTHER BENEFITS

     Effective March 31, 2000, participation by the Company's employees in Duke
Energy's non-contributory trustee pension plan and employee savings plan were
terminated. Effective April 1, 2000, the Company's employees began participation
in the Company's employee savings plan, in which the Company contributes 4% of
each eligible employee's qualified wages. Additionally, the Company matches
employees' contributions to the plan up to 6% of qualified wages.

10. BUSINESS SEGMENTS

     The Company operates in two principal business segments as follows: (1)
natural gas gathering, processing, transportation, marketing and storage, and
(2) natural gas liquids fractionation, transportation, marketing and trading.
These segments are monitored separately by management for performance against
its internal forecast and are consistent with the Company's internal financial
reporting. These segments have been identified based on the differing products
and services, regulatory environment and the expertise required for these
operations. Margin, earnings before interest, taxes, depreciation and
amortization (EBITDA) and earnings before interest and taxes (EBIT) are the
performance measures utilized by management to monitor

the business of each segment. The accounting policies for the segments are the
same as those described in Note 1. Foreign operations are not material and are
therefore not seperately identified.

     The following table sets forth the Company's segment information for the
three months ended March 31, 1999 and 2000 and as of December 31, 1999 and March
31, 2000.

(a) Intersegment sales represent sales of NGLs from the Natural Gas segment to
    the NGLs segment at either index prices or weighted average prices of NGLs.
    Both measures of intersegment sales are effectively based on current
    economic market conditions.


(b) EBITDA consists of income from continuing operations before interest
    expense, income tax expense, and depreciation and amortization expense, less
    interest income. EBITDA is not a measurement presented in accordance with
    generally accepted accounting principles. You should not consider it in
    isolation from or as a substitute for net income or cash flow measures
    prepared in accordance with generally accepted accounting principles or as a
    measure of our profitability or liquidity. EBITDA is included as a
    supplemental disclosure because it may provide useful information regarding
    our ability to service debt and to fund capital expenditures. However, not
    all EBITDA may be available to service debt.


(c) Includes items such as unallocated working capital, intercompany accounts
    and intangible and other assets.

                         REPORT OF INDEPENDENT AUDITORS

The Board of Directors and Stockholder
Phillips Gas Company

     We have audited the accompanying consolidated balance sheets of Phillips
Gas Company as of December 31, 1998 and 1999, and the related consolidated
statements of income, changes in stockholders' equity (deficit) and cash flows
for each of the three years in the period ended December 31, 1999. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

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

     In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Phillips Gas
Company at December 31, 1998 and 1999, and the consolidated results of its
operations and its cash flows for each of the three years in the period ended
December 31, 1999, in conformity with accounting principles generally accepted
in the United States.

                              PHILLIPS GAS COMPANY

                         NOTES TO FINANCIAL STATEMENTS

1. ACCOUNTING POLICIES

     Consolidation Principles and Basis of Presentation -- Phillips Gas Company
(PGC or the company) is a subsidiary of Phillips Petroleum Company (Phillips).
Phillips owns 100 percent of the company's outstanding common stock.
Majority-owned, controlled subsidiaries are consolidated. Investments in
affiliates in which the company owns 20 percent to 50 percent of voting control
are accounted for using the equity method.

     Use of Estimates -- The preparation of financial statements in conformity
with generally accepted accounting principles requires Management to make
estimates and assumptions that affect the reported amounts of assets,
liabilities, revenues and expenses, and the disclosures of contingent assets and
liabilities. Actual results could differ from the estimates and assumptions
used.

     Cash and Cash Equivalents -- Cash and cash equivalents are held by Phillips
as part of its centralized cash management system. Interest is paid monthly
based on the average daily balance of funds invested at a rate equal to the
weighted-average rate earned by Phillips or at the applicable federal funds
rate.

     Cash equivalents are highly liquid short-term investments that are readily
convertible to known amounts of cash and have original maturities within three
months from their date of purchase.

     Inventories -- Helium inventory is valued at cost, which is lower than
market, mainly on the last-in, first-out (LIFO) basis. Materials and supplies
are valued at, or below, average cost.

     Derivative Contracts -- The company uses commodity swap and option
contracts. Commodity option contracts are recorded at market value through
monthly adjustments for unrealized gains and losses; however, swaps are not
marked to market. Gains and losses are recognized during the same period in
which the gains and losses from the underlying exposures being hedged are
recognized. In 1998 and 1999, the net realized and unrealized gains and losses
from derivative contracts were not material to the company's financial
statements.

     Revenue Recognition -- Revenues associated with sales of natural gas,
natural gas liquids, and all other items are recorded when title passes to the
customer upon delivery.

     Gas Exchanges and Imbalances -- Quantities of gas over-delivered or
under-delivered related to exchange or imbalance agreements are recorded monthly
as receivables or payables using the index price or the average price of gas at
the plant or system. Generally, these balances are settled with deliveries of
gas.

     Depreciation -- Depreciation of plants and systems is determined using the
straight-line method over an estimated life of 20 years for most of the assets.
Other properties and equipment are depreciated using the straight-line method
over the estimated useful lives of the assets. (See Note 5)

     Impairment of Assets -- Long-lived assets used in operations are assessed
for impairment whenever changes in facts and circumstances indicate a possible
significant deterioration in the future cash flows expected to be generated by
an asset group. If, upon review, the sum of the undiscounted pretax cash flows
are less than the carrying value of the asset group, the carrying value is
written down to estimated fair value.

     The expected future cash flows used for impairment reviews and related fair
value calculations are based on the production volumes, prices and costs used
for planning purposes by the company, considering all available evidence at the
date of the review. These may differ from levels prevalent at the impairment
review date due to anticipated changes in outlook for production levels, supply
and demand influences in the marketplace, and general inflation.

     Property Dispositions -- When complete units of depreciable property are
retired or sold, the asset cost and related accumulated depreciation are
eliminated, with any gain or loss reflected in income. When less than complete
units of depreciable property are disposed of or retired, the difference between
asset cost and salvage value is charged or credited to accumulated depreciation.

                              PHILLIPS GAS COMPANY

                    NOTES TO FINANCIAL STATEMENTS--CONTINUED

     Environmental Costs -- Environmental expenditures are expensed or
capitalized as appropriate, depending upon their future economic benefit.
Expenditures that relate to an existing condition caused by past operations, and
that do not have future economic benefit, are expensed. Liabilities for these
expenditures are recorded on an undiscounted basis when environmental
assessments or clean-ups are probable and the costs can be reasonably estimated.

     Income Taxes -- Deferred taxes are computed using the liability method and
provided on all temporary differences between the financial reporting basis and
the tax basis of the assets and liabilities. Allowable tax credits are applied
currently as reductions of the provision for income taxes. The company's results
of operations for 1998 and 1999 were included in the consolidated federal income
tax return of Phillips, with any resulting tax liability or refund settled with
Phillips on a current basis. Income tax expense represents amounts due Phillips
for federal income taxes as if the company were filing a separate return, except
that the same principles and elections used in the consolidated return were
applied. Results of operations for 1997 were included in the separate federal
income tax return of Phillips Gas Company.

     Income Per Share of Common Stock -- Income per share of common stock has
been omitted from the consolidated statement of income because all common stock
is owned by Phillips.

     Comprehensive Income -- The company does not have any items of other
comprehensive income, as defined in Financial Accounting Standards Board (FASB)
Statement No. 130, "Reporting Comprehensive Income."

2. THE COMPANY'S BUSINESS

     The company owns and operates natural gas gathering systems and processing
facilities concentrated in four major gas-producing areas in the Southwest. The
company's core gathering and processing regions are concentrated in the Permian
Basin area of West Texas and southeastern New Mexico, the Panhandle areas of
Texas and Oklahoma, and central and western Oklahoma. Under FASB Statement No.
131, "Disclosures about Segments of an Enterprise and Related Information," the
four regions have been aggregated into a single segment for financial reporting
purposes. At December 31, 1999, the company wholly owned 15 natural gas liquids
extraction plants, and had an interest in another. The plants are located in
Texas (9), Oklahoma (3), and New Mexico (4). During 1999, the company purchased
a co-venturer's interest in the Artesia plant and gathering system in New Mexico
that the company had operated under a construction and operating agreement since
1959.

     The company sells substantially all of its natural gas liquids to Phillips.
The company is able to interconnect to major gas transmission pipelines in each
of its regions in order to sell residue gas to local distribution companies,
electric utilities, various other business and industrial users and marketers.
The company's major residue gas markets are located primarily in Texas, Oklahoma
and the midwestern United States.

3. INVENTORIES

     Inventories at December 31 consisted of the following:

</TABLE>

     In 1993 the company formed GPM Gas Gathering L.L.C. (GGG), a limited
liability company in which PGC invested approximately $4 million in exchange for
a 50 percent equity interest. In December 1993, the company sold a portion of
its gas gathering assets in the West Texas region of the Permian Basin to GGG
for $138 million. GGG is providing gas gathering services to the company under a
twenty-year contract. This contract does not represent a take-or-pay or
unconditional purchase obligation. Because of the company's continuing
involvement in GGG, a $22 million gain from the sale of the assets was deferred
and is being recognized over the economic life of the gathering assets. The
deferred gain recognized during 1998 and 1999 was $1,082,000 and $1,083,000,
respectively. Distributions received from GGG during 1998 and 1999 were
$1,153,000 and $955,000 respectively. See Note 10 for the gathering fees paid by
the company to GGG under this contract.

                              PHILLIPS GAS COMPANY

                    NOTES TO FINANCIAL STATEMENTS--CONTINUED

     On December 9, 1999, Phillips Gas Company declared and distributed a
dividend to Phillips in the form of a note payable in the amount of $780
million. The note payable is due in full at maturity on December 9, 2002, bears
interest at a rate of 5.74 percent per annum, and may be paid prior to maturity
at any time without penalty or premium. The amount of the dividend exceeded the
company's historical-cost-based net assets, resulting in a negative balance in
stockholder's equity.

     The declaration and payment of dividends is at the discretion of the
company's Board of Directors. In connection with each dividend declaration, the
Board of Directors makes a determination that, based upon its familiarity with
the company's business, prospects and financial condition, the company's recent
earnings history and forecast, an appraisal of the company's assets and
discussions with the company's executive officers, attorneys and accountants,
the dividend is a permitted dividend under Delaware law. This determination was
made prior to the declaration of the $780 million dividend made on December 9,
1999.

     The note due 2001 bears interest at LIBOR plus 1/2 percent per annum (6.33
percent at December 31, 1999). Any amount repaid may be reborrowed as long as
the agreement is in effect. The note due 2005 bears interest at the applicable
federal mid-term rate (6.03 percent monthly rate for December 1999). The
carrying amount of the floating-rate debt approximates fair value.

7. FINANCIAL INSTRUMENTS

  Concentrations of Credit Risk

     The company's financial instruments that are exposed to concentrations of
credit risk consist primarily of cash equivalents, accounts receivable and
over-the-counter derivative contracts. Derivative contracts are immaterial to
the financial statements of the company.

     The company's cash and cash equivalents are held by Phillips as part of its
centralized cash management system. Cash equivalents are in high-quality
securities placed with major international banks and financial institutions.
Phillips' investment policy limits the company's exposure to concentrations of
credit risk with respect to its cash equivalent investments.

     The company's affiliate receivables result primarily from its sales of
natural gas liquids and residue gas to Phillips. The company's trade receivables
result primarily from domestic sales of residue gas to local distribution
companies, electric utilities, various other business and industrial end-users,
and marketers. The company routinely assesses the financial strength of its
unaffiliated residue-gas customers. The company considers its concentrations of
credit risk, other than those with Phillips, to be limited.

  Fair Values of Financial Instruments

     The following methods and assumptions were used by the company in
estimating the fair value of its financial instruments:

          Cash and cash equivalents: The carrying amount reported in the balance
     sheet approximates fair value because of the short-term nature of these
     investments.

          Deferred purchase obligation due within one year: The carrying amount
     reported in the balance sheet approximates fair value because of the
     short-term nature of the obligation.

          Long-term debt: The carrying amount of the company's floating- and
     fixed-rate debt approximates fair value based on current market rates.

                    NOTES TO FINANCIAL STATEMENTS--CONTINUED

8. PREFERRED STOCK

     On December 15, 1997, the company redeemed its 13,800,000 shares of Series
A 9.32% Cumulative Preferred Stock at par. The liquidation value for each Series
A preferred share was $25, plus $.2006 for unpaid dividends.

9. CONTINGENT LIABILITIES

     The company is a party to a number of legal proceedings pending in various
courts or agencies for which no provision has been made. Costs related to
contingencies are provided when a loss is probable and the amount can be
reasonably estimated. These accruals are not discounted for delays in future
payment and are not reduced for potential insurance recoveries. If applicable,
undiscounted receivables are accrued for probable insurance recoveries.

     A judgment has been entered in the case of Chevron U.S.A., Inc. versus GPM
Gas Corporation (GPM), a wholly owned subsidiary of the company, upholding and
construing most favored nations clauses in three 1961 West Texas gas purchase
contracts. Although a federal district court decided that GPM owes Chevron
damages in the amount of $13,828,030 through July 31, 1998, plus 6 percent
interest from that date and attorneys' fees in the amount of $329,994, GPM has
appealed the judgment to the U.S. Court of Appeals for the Fifth Circuit.

     Based on currently available information, after taking into consideration
amounts already accrued and the pending appeal in the Chevron litigation, PGC
believes that any liability resulting from any of the above matters will not
have a material adverse effect on its financial statements. However, such
matters could have a material effect on results of operations in a particular
quarter or fiscal year as they develop or as new issues are identified.

(a)  The company sells a portion of its residue gas and other by-products to
     Phillips at contractual prices that approximate market prices. The company
     sells substantially all of its natural gas liquids to Phillips at prices
     based upon quoted market prices for fractionated natural gas liquids, less
     charges for transportation, fractionation and quality-adjustment fees.
     Effective January 1, 2000, the pricing formula contained in the natural gas
     liquids supply arrangement with Phillips was renegotiated, as allowed under
     the contract, to reflect current market conditions. The new arrangement
     will be maintained for an initial term of 15 years. PGC believes that the
     loss of Phillips as a natural gas liquids customer would have a material,
     adverse effect on its revenues and operating results.

(b)  The company purchases raw gas from Phillips at contractual prices that
     approximate market prices. During 1999, Phillips provided the company with
     approximately 8 percent of its raw gas throughput, under long-term supply
     contracts, making Phillips its largest single supplier. PGC believes that

     Phillips as a raw gas supplier would have a material adverse effect on its
     dedicated raw gas supplies and its operating results.

(c)  Phillips provides the company with various field services (costs included
     in operating expenses) and other general administrative services (costs
     included in selling, general and administrative expenses) including
     insurance, personnel administration, office space, communications, data
     processing, engineering, automotive and other field equipment, and other
     miscellaneous services. Charges for these services and benefits are based
     on usage and actual costs or other allocation methods the company considers
     reasonable.

(d)  Phillips charges the company a portion of its corporate indirect overhead
     costs including executive, legal, treasury, planning, tax, auditing and
     other corporate services, under an administrative services agreement.
     Charges for these services and benefits are based on usage and actual costs
     or other allocation methods the company considers reasonable.

(e)  All operational and staff personnel requirements are met by Phillips'
     employees, most of whom are associated with the GPM Gas Services Company
     division of Phillips. All services provided by Phillips, including (c) and
     (d) above, are priced to reimburse Phillips for its actual costs. Charges
     for these services and benefits are based on usage and actual costs or
     other allocation methods the company considers reasonable. Selling, general
     and administrative expenses included a severance charge reversal of $2
     million in 1998, and a $2 million severance charge in 1999.

(f)  The company earns interest from participation in Phillips' centralized cash
     management system.

(g)  The company incurs interest expense on borrowings from and debt to
     Phillips.

(h)  Beginning January 1, 1994, the company began paying GGG a fee for gas
     gathering services under a long-term contract. The gas gathering fee
     structure in the long-term contract contains a component that is paid to
     GGG in an accelerated manner. Because GGG is providing the same gas
     gathering services to the company over the contract period, recognition of
     expenses related to this component of the gathering fee is deferred and
     recognized on a straight-line basis through the remaining period of the
     long-term contract. In 1997, 1998 and 1999, the total gathering fees were
     $42,755,000, $42,951,000 and $41,447,000, respectively, of which
     $34,952,000, $35,720,000 and $34,316,000, respectively, were expensed.

     The company provides Phillips with other minor administrative services.
Costs allocated to Phillips for these services have been netted against the
above direct charges from Phillips and were $120,000, $79,000 and $72,000 in
1997, 1998 and 1999, respectively.

     The company periodically buys from, or sells to, Phillips various assets
used in the operations of the business. These net acquisitions were recorded at
the assets' historical net book values, which generally approximated fair market
value, and totaled $22,000, $60,000 and $239,000 in 1997, 1998 and 1999,
respectively. Prior to such acquisition or sale, the company paid or received a
fee based on usage of such assets (included in operating expenses above). In
addition, the company purchases plastic pipe from Phillips, which is used in the
construction of gathering systems. Purchases in 1997, 1998 and 1999 were
$3,942,000, $2,276,000 and $2,175,000, respectively.

11. EMPLOYEE BENEFIT PLANS

     Substantially all employees of Phillips' GPM Gas Services Company division
participate in Phillips' benefit plans, including pension plans, defined
contribution plans, stock option plans and health and life insurance plans.
Costs are allocated to the company based principally on base payroll costs of
participating employees. Total benefit plan costs charged to the company were
$22,095,000, $22,522,000 and $21,005,000 for the years ended 1997, 1998 and
1999, respectively.

     The tax bases in the company's assets were increased as a result of the
1992 transfer of substantially all of its assets to GPM Gas Corporation and the
subsequent issuance and sale of preferred stock. The net operating loss
carryforwards and the alternative minimum tax credit carryforwards resulted
primarily from tax depreciation on the increased bases in the company's assets.

     The company believes it is more likely than not that it will fully realize
its deferred tax assets, and, accordingly, a valuation allowance has not been
provided. Management expects that the deferred tax assets will be realized as
reductions in future taxable operating income or by utilizing available tax
planning strategies. Uncertainties that may affect the realization of these
assets include tax law changes, change in control as discussed in Note 16, and
the future level of product costs. Therefore, the company periodically reviews
its ability to realize these assets and will establish a valuation allowance if
needed.

     At December 31, 1999, the company had net operating loss carryforwards of
$71 million for U.S. income tax purposes, and $221 million for state income tax
purposes. The U.S. income tax carryforwards begin

expiring in 2009, and the state income tax carryforwards begin expiring in 2000.
The alternative minimum tax credit can be carried forward indefinitely to reduce
the company's regular tax liability.

13. KEEP WELL REPLACEMENT AGREEMENT

     The redemption of the company's outstanding shares of Series A 9.32%
Cumulative Preferred Stock on December 15, 1997, cancelled the previous Keep
Well Agreement and triggered the need for a Keep Well Replacement Agreement
between Phillips and PGC. The Keep Well Replacement Agreement provides for
Phillips to maintain PGC's consolidated tangible net worth in an amount not less
than $50 million, or to irrecoverably and unconditionally guaranty the full and
timely performance, payment and discharge by PGC of all its obligations and
liabilities. Effective February 1, 2000, Phillips furnished a guaranty to GGG
assuring payment by PGC of all its existing or future obligations and
liabilities to GGG.

announced that they had signed definitive agreements to combine the two
companies' gas gathering, processing and marketing

businesses to form a new midstream company to be called Duke Energy Field
Services, LLC (Field Services LLC). The definitive agreements have been
unanimously approved by both companies' Boards of Directors. Subject to
regulatory approval, the transaction is expected to close by the end of the
first quarter of 2000.

     If the transaction closes as expected, the subsidiaries of PGC will be
contributed to Field Services LLC in a partially tax-free exchange, and those
subsidiaries will cease to be wholly owned subsidiaries of Phillips. As part of
the transaction, the existing natural gas liquids purchase contract between
Phillips and the company will be maintained by the new company for an initial
term of 15 years. At closing, Duke Energy will own about 70 percent of Field
Services LLC, and Phillips will own about 30 percent.

17. IMPACT OF TRANSITION TO YEAR 2000 (UNAUDITED)

     PGC relies on Phillips for computer systems, hardware and software for
operation of its facilities and business support systems. PGC's operations and
facilities were included as part of Phillips' companywide Year 2000 Project that
addressed the issue of computer programs and embedded computer chips being
unable to distinguish between the year 1900 and the year 2000. That project is
now complete. With the rollover into 2000, neither PGC nor Phillips experienced
any significant Year 2000 failures. Some minor Year 2000 issues occurred and
were resolved, but none have had a material impact on PGC's results of
operations, liquidity, financial condition or safety record. The total costs
associated with Year 2000 issues were not material to PGC's or Phillips'
financial position. Phillips continues to monitor its mission-critical computer
applications and those of its suppliers and vendors throughout the year 2000 to
ensure that any latent Year 2000 matters that may arise are addressed promptly.

                              PHILLIPS GAS COMPANY

                         NOTES TO FINANCIAL STATEMENTS

1. INTERIM FINANCIAL INFORMATION

     The financial information for the interim periods presented in the
financial statements included in this report is unaudited and includes all known
accruals and adjustments that Phillips Gas Company (PGC or the company)
considers necessary for a fair statement of the results for such periods. All
such adjustments are of a normal and recurring nature.

2. BUSINESS COMBINATION

     On March 31, 2000, Phillips Petroleum Company (Phillips) combined its gas
gathering, processing and marketing business with Duke Energy Corporation's
(Duke Energy) gas gathering, processing and marketing business to form a new
midstream company called Duke Energy Field Services LLC (DEFS).

     PGC contributed its holdings in its limited-liability-company subsidiaries
to DEFS in a tax-free exchange. The operations of these subsidiaries comprise
substantially all of the operations of PGC. Effective March 31, 2000, the
company is accounting for its investment in DEFS using the equity method.

     In connection with the combination DEFS borrowed approximately $2.75
billion of short-term debt. In April 2000, the proceeds of the debt were used to
make one-time cash distributions of approximately $1,525 million to Duke Energy
and $1,220 million to Phillips. Duke Energy owns about 70 percent of DEFS, and
Phillips, through PGC, owns about 30 percent.

3. INCOME TAXES

     The company's effective tax rate for the first three months of 1999 was 41
percent, compared with 39 percent for the same period of 2000.

     Deferred income taxes are computed using the liability method and provided
on all temporary differences between the financial reporting basis and the tax
basis of the assets and liabilities. Allowable tax credits are applied currently
as reductions of the provision for income taxes. The results of operations for
1999 and 2000 are included in the consolidated federal income tax return of
Phillips, with any resulting tax liability or refund settled with Phillips on a
current basis. Income tax expense represents PGC on a separate return basis,
except that the same principles and elections used in the consolidated return
were applied.

4. RELATED PARTY TRANSACTIONS

     Significant transactions with affiliated parties were:

</TABLE>

     Prior to the contribution of its subsidiaries to DEFS on March 31, 2000,
the company purchased raw gas from, and sold a portion of its residue gas and
substantially all of its natural gas liquids to, Phillips. Phillips also
provided the company with various field and general administrative services. In
addition, the company purchased Phillips' plastic pipe, which is used in the
construction of gathering systems.

                   NOTES TO FINANCIAL STATEMENTS -- CONTINUED

     The company earns interest from participation in Phillips' centralized cash
management system and incurs interest expense on its borrowings from Phillips.

     The company paid gathering fees to GPM Gas Gathering L.L.C. (GGG) until it
contributed its equity interest in GGG into DEFS on March 31, 2000. In the first
three months of 1999 and 2000, net fees paid to GGG for gas gathering services
were $10,334,831 and $10,101,951, respectively; $8,655,478 and $8,450,827 were
expensed.

     Selling, general and administrative expenses included a $2 million
severance charge during the first three months of 1999.

5. CASH FLOW INFORMATION

NON-CASH INVESTING ACTIVITIES

     On March 31, 2000, the company contributed its holdings in its
limited-liability-company subsidiaries to DEFS. The contribution included
property, plant and other assets and liabilities held by these companies, except
for cash invested with Phillips, deferred taxes and current taxes payable.

     Other non-cash investing activities and cash payments for the three-month
periods ended March 31 were as follows:

     We have audited the accompanying combined statements of income and cash
flows of the UPFuels Division of Union Pacific Resources Group Inc. (a Utah

these financial statements based on our audits.

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

     In our opinion, the combined financial statements referred to above present
fairly, in all material respects, the combined results of operations and cash
flows of the UPFuels Division for the year ended December 31, 1998, and the
three-month period ended March 31, 1999, in conformity with accounting

                     NOTES TO COMBINED FINANCIAL STATEMENTS

SIGNIFICANT ACCOUNTING POLICIES

     Principles of Combination. The combined financial statements include the
accounts of certain gathering, processing, transporting and marketing operations
of companies which are wholly-owned subsidiaries of Union Pacific Resources
Group Inc. ("UPR"), a Utah Corporation. In addition, the combined financial
statements include the operations of certain gathering and processing assets
owned by wholly-owned subsidiaries of UPR that are not included in their
entirety herein. Collectively, these wholly-owned subsidiaries and assets are
considered and referred to herein as the "UPFuels Division" of UPR. All material
intra-divisional transactions have been eliminated.

     The UPFuels Division accounts for its investments in pipeline partnerships
and joint ventures under the equity method of accounting for entities owned
20%-50% by the UPFuels Division and fully consolidates entities owned greater
than 50% by the UPFuels Division. The minority interest recorded by the UPFuels
Division represents the ownership of other parties in entities in which the
UPFuels Division owns greater than 50% but less than 100%.

     Use of Estimates. The preparation of financial statements in conformity
with generally accepted accounting principles requires management to make
estimates and assumptions. These estimates and assumptions affect the reported
amounts of assets, liabilities, revenues and expenses and disclosure of
contingent assets and liabilities. Management believes its estimates and
assumptions are reasonable; however, there are a number of risks and
uncertainties which may cause actual results to differ materially from the
estimates.

     Depreciation and amortization. Provisions for depreciation of property,
plant and equipment are computed on the straight-line method based on estimated
service lives which range from three to 30 years. The cost of acquired gas
purchase and marketing contracts are amortized using the straight-line method
over the applicable period. Goodwill is being amortized using the straight-line
method over 20 years. Amortization of goodwill was $2.0 million, $4.5 million
and $1.1 million for the years ended December 31, 1997 and 1998 and for the
quarter ended March 31, 1999, respectively. The value of goodwill is
periodically evaluated based on the expected future undiscounted operating cash
flows to determine whether any potential impairment exists.

     Revenue Recognition. The UPFuels Division recognizes revenues as gas and
natural gas liquids are delivered and services are rendered. Revenues are
recorded on an accrual basis, including an estimate for gas and natural gas
liquids delivered but unbilled at the end of each accounting period.

     Derivative Financial Instruments. Unrealized gains/losses on derivative
financial instruments used for hedging purposes are not recorded. Recognition of
realized gains/losses and option premium payments/receipts are deferred and
recorded in the combined statement of income when the underlying physical
product is purchased or sold. The cash flow impact of derivative and other
financial instruments is reflected in cash provided by operations in the
combined statements of cash flows.

     Income Taxes. The UPFuels Division is included in the consolidated Federal
income tax return of UPR. The consolidated Federal income tax liability of UPR
is allocated among all corporate entities on the basis of the entity's
contributions to the consolidated Federal income tax liability. Full benefit of
tax losses and credits made available and utilized in UPR's consolidated Federal
income tax returns are being allocated to the individual companies generating
such items. Income tax expense represents federal income taxes as if the company
were filing a separate return.

     Environmental Expenditures. Environmental expenditures related to treatment
or cleanup are expensed when incurred, while environmental expenditures which
extend the life of the property or prevent future contamination are capitalized
in accordance with generally accepted accounting principles. Liabilities for
these expenditures are recorded when it is probable that obligations have been
incurred and the amounts can

be reasonably estimated, based on current law and existing technologies.
Environmental accruals are recorded at undiscounted amounts and exclude claims
for recoveries from insurance or other third parties.

     Earnings Per Share. Earnings per share have been omitted from the combined
statements of income as the UPFuels Division was wholly owned by UPR for all
periods presented.

1. NATURE OF OPERATIONS

     The UPFuels Division owns and operates natural gas and natural gas liquids
gathering and pipeline systems and gas processing plants and is engaged in the
business of purchasing, gathering, processing, transporting, storing and
marketing natural gas and natural gas liquids. Through a related party
transaction, the UPFuels Division markets a substantial portion of UPR's natural
gas and natural gas liquid production together with significant volumes of
natural gas and natural gas liquids produced by others. The UPFuels Division has
a diverse customer base for its hydrocarbon products.

     The UPFuels Division's results of operations are largely dependent on the
difference between the prices received for its hydrocarbon products and the cost
to acquire and market such resources. Hydrocarbon prices are subject to
fluctuations in response to changes in supply, market uncertainty and a variety
of factors beyond the control of the UPFuels Division. These factors include
worldwide political instability, the foreign supply of oil and natural gas, the
price of foreign imports, the level of consumer demand and the price and
availability of alternative fuels. Historically, the UPFuels Division has been
able to manage a portion of the operating risk relating to hydrocarbon price
volatility through hedging activities.

2. ACQUISITION OF THE UPFUELS DIVISION BY DUKE ENERGY FIELD SERVICES INC.

     In November 1998, UPR reached an agreement with Duke Energy Field Services,
Inc. whereby Duke Energy Field Services would acquire certain gathering,
processing, pipeline and marketing assets of UPR. The sale transaction closed
effective March 31, 1999, with the purchase price being $1.35 billion. Certain
liabilities primarily income tax and retiree benefits obligations, were not
assumed by Duke Energy Field Services in connection with the sale transaction.

3. RELATED PARTY TRANSACTIONS

     The UPFuels Division enters into certain natural gas and crude hedging
transactions on behalf of UPR. Services performed by UPR on behalf of the
UPFuels Division include cash management, internal audit and tax and employee
benefits administration. Expenses for these services are included in the
statements of income and are $2.0 million and $2.0 million for the years ended
1997 (As Restated) and 1998 respectively and $.5 million for the quarter ended
March 31, 1999. Other general and administrative expenses have been allocated to
the UPFuels Division, including office rent expense. Since treasury is
considered to be a UPR corporate function, no interest expense has been
allocated to the UPFuels Division in the accompanying combined statements of
income.

     The UPFuels Division has a buy/sell agreement with UPR. Under this
agreement, the UPFuels Division gathers, transports, processes and sells natural
gas and natural gas liquids for UPR and purchases natural gas and natural gas
liquids from UPR.

     The charges for allocated services are based on estimated full time
equivalent headcount at fully burdened rates. The buy/sell arrangements are
based on prevailing market conditions in each regional area. Accordingly, these
transactions reflect UP Fuels results as if they were on a stand alone basis.

     The following table reflects the intercompany balance outstanding at each
period end as well as the high and low balance for each period.

4. SIGNIFICANT ACQUISITION

     Highlands Gas Corporation. In August 1997, the UPFuels Division acquired
100% of the outstanding stock of Highlands Gas Corporation ("Highlands") for an
adjusted purchase price of approximately $179.4 million. Highlands is in the
business of gathering, purchasing, processing and transporting natural gas and
natural gas liquids. The acquisition included three natural gas processing
plants, five gathering systems with over 700 miles of gas and natural gas
liquids gathering pipeline and 400 miles of transportation pipeline located in
Western Texas and Eastern New Mexico. Results of operations for Highlands
subsequent to the acquisition date are included in the consolidated statements
of income.

     The following unaudited pro forma combined results of operations for the
year ended December 31, 1997 are presented as if the Highlands acquisition had
been made at the beginning of the year. The unaudited pro forma information is
not necessarily indicative of either the results of operations that would have
occurred had the purchase been made during the periods presented or the future
results of the combined operations.

5. FINANCIAL INSTRUMENTS

     Hedging. The UPFuels Division has established policies and procedures for
managing risk within its organization. It is balanced by internal controls and
governed by a risk management committee. The level of risk assumed by the
UPFuels Division is based on its objectives and earnings, and its capacity to
manage risk. Limits are established for each major category of risk, with
exposures monitored and managed by UPFuels

                                      F-64

               NOTES TO COMBINED FINANCIAL STATEMENTS--CONTINUED

Division management, and reviewed semi-annually by the risk management
committee. Major categories of the UPFuels Division's risk are defined as
follows:

     Commodity Price Risk -- Non-Trading Activities. The UPFuels Division uses
derivative financial instruments for non-trading purposes in the normal course
of business to manage and reduce risks associated with contractual commitments,
price volatility, and other market variables in conjunction with transportation,
storage, and customer service programs. These instruments are generally put in
place to limit risk of adverse price movements, however, when this is done,
these same instruments usually limit future gains from favorable price
movements. Such risk management activities are generally accomplished pursuant
to exchange-traded contracts or over-the-counter options.

     Recognition of realized gains/losses and option premium payments/receipts
are also deferred in the combined statements of income until the underlying
physical product is sold. Unrealized gains/losses on derivative financial
instruments are not recorded. The cash flow impact of derivative and other
financial instruments is reflected as cash flows provided from operations in the
combined statements of cash flows.

     Commodity Price Risk -- Trading Activities. Periodically, the UPFuels
Division may enter into transactions involving a wide range of energy related
derivative financial transactions that are not the result of hedging activities.
These instruments are generally put into place based on the UPFuels Division's
analysis and expectations with respect to price movement or changes in other
market variables. As of March 31, 1999, there were no transactions in place
which would materially affect the results of operations or financial condition
of the UPFuels Division.

     Credit Risk. Credit risk is the risk of loss as a result of nonperformance
by counterparties pursuant to the terms of their contractual obligations.
Because the loss can occur at some point in the future, a potential exposure is
added to the current replacement value to arrive at a total expected credit
exposure. The UPFuels Division has established methodologies to establish
limits, monitor and report creditworthiness and concentrations of credit to
reduce such credit risk. At March 31, 1999, the UPFuels Division's largest
credit risk associated with any single counterparty, represented by the net fair
value of open contracts with such counterparty was $2.2 million.

     Performance Risk. Performance risk results when a counterparty fails to
fulfill its contractual obligations such as commodity pricing or volume
commitments. Typically, such risk obligations are defined within the trading
agreements. The UPFuels Division utilizes its credit risk methodology to manage
performance risk.

     Concentrations of Credit Risk. Financial instruments which subject the
UPFuels Division to concentrations of credit risk consist principally of trade
receivables and short-term cash investments. A significant portion of the
UPFuels Division's trade receivables relate to customers in the energy industry,
and, as such, the UPFuels Division is directly affected by the economy of that
industry. However, excluding the relationship with UPR, the credit risk
associated with trade receivables is minimized by the UPFuels Division's diverse
customer base which includes local gas distribution companies, power generation
facilities, pipelines, industrial plants and other wholesale marketing
companies. Ongoing procedures are in place to monitor the creditworthiness of
customers. The UPFuels Division generally requires no collateral from its
customers and historically has not experienced significant losses on trade
receivables.

6. INCOME TAXES

     The UPFuels Division is included in the consolidated Federal income tax
return of UPR. The consolidated Federal income tax liability of UPR is allocated
among all corporate entities on the basis of the entity's contributions to the
consolidated Federal income tax liability. Full benefit of tax losses and
credits made available and utilized in UPR's consolidated Federal income tax
returns are being allocated to the individual companies generating such items.

     All tax years prior to 1986 have been closed with the Internal Revenue
Service ("IRS"). On behalf of the UPFuels Division, UPR, through Union Pacific
Corporation ("UPC"), is negotiating with the Appeals Office concerning 1986
through 1989. The IRS is examining UPR's returns for 1990 through 1994 in
connection with the IRS' examination of UPC's returns. The UPFuels Division
believes it has adequately provided for Federal and state income taxes.

7. LEASES

     The UPFuels Division leases certain compressors and other property. Future

     Rent expense for operating leases with terms exceeding one year was $1.1
million and $1.3 million for the years ended December 31, 1997 and 1998,
respectively, and $0.5 million for the quarter ended March 31, 1999. Currently
there is no sublease income for the next five years or thereafter.

8. EMPLOYEE STOCK OPTION PLANS

     Stock Option and Retention Stock Plans. Pursuant to the UPR's stock option
and retention stock plans, UPR stock options under the plans are granted at 100%
of fair market value at the date of grant, become exercisable no earlier than
one year after grant and are exercisable for a period of up to eleven years from
grant date. Option grants have been made to directors, officers and employees
and vest over a period up to ten years from the grant date.

     Retention shares of UPR common stock are awarded under the plans to
eligible employees, subject to forfeiture if employment terminates during the
prescribed retention period, generally one to five years from grant. Multi-year
retention stock awards also have been made, with vesting two to five years from
grant.

     Expense related to these stock option and retention stock programs of UPR,
which pertain to UPFuels Division employees, amounted to $1.2 million, $1.3
million and $.7 million for the years ended 1997 and 1998 and the quarter ended
March 31, 1999, respectively.

     Since UPR applies the intrinsic value method in accounting for its stock
option and retention stock plans, it generally records no compensation cost for
its stock option plans. Had compensation cost for UPR's stock option plan been
determined based on the fair value at the grant dates for awards to UPFuels
Division employees under the plan and for options that were converted at the
times of the initial public offering and spin-off of UPR from UPC, the UPFuels
Division's net income would have been reduced by $.6 million, $1.9 million and
$0.1 million for the years ended December 31, 1997 and 1998 and the quarter
ended March 31, 1999, respectively.

     Employee Stock Ownership Plan. Effective January 2, 1997, UPR instituted an
employee stock ownership plan ("ESOP"). The ESOP purchased 3.7 million shares or
$107.3 million of newly issued common stock (the "ESOP Shares") from UPRG, which
will be used to fund UPR's matching obligation under its 401(k) Thrift Plan. All
regular employees of the UPFuels Division are eligible to participate in the
ESOP.

     During the years ended December 31, 1997 and 1998, and the quarter ended
March 31, 1999, compensation cost related to the allocation of ESOP shares to
participants' accounts was $1.4 million, $1.6 million and $0.4 million,
respectively, for the UPFuels Division.

9. ENVIRONMENTAL EXPOSURE

     The UPFuels Division generates and disposes of hazardous and nonhazardous
waste in its current and former operations and is subject to increasingly
stringent Federal, state and local environmental regulations. Certain Federal
legislation imposes joint and several liability for the remediation of various
sites; consequently, the UPFuels Division's ultimate environmental liability may
include costs relating to other parties in addition to costs relating to its own
activities at each site. In addition, the UPFuels Division is or may be liable
for certain environmental remediation matters involving existing or former
facilities.

     The UPFuels Division has recorded environmental reserves related to future
costs of all sites where the UPFuels Division's obligation is probable and where
such costs reasonably can be estimated. This accrual includes future costs for
remediation and restoration of sites, as well as for ongoing monitoring costs,
but excludes any anticipated recoveries from third parties.

     The UPFuels Division also is involved in reducing emissions, spills and
migration of hazardous materials. Remediation of identified sites and control of
environmental exposures required $1.2 million in 1998 and no spending for the
quarter ended March 31, 1999.

10. COMMITMENTS AND CONTINGENCIES

     The UPFuels Division is party to several long-term firm gas transportation
agreements, the largest of which are with Kern River Gas Transportation Company
("Kern River"), Texas Gas Transmission Corporation ("Texas Gas"), and Pacific
Gas Transmission ("PGT"). At December 31, 1997, the UPFuels Division had a keep
whole agreement with UPR which expired at the end of 2003 whereby UPR reimbursed
the UPFuels Division for the excess of the contractual fixed price over the
prevailing market price for the transportation. Conversely, the UPFuels
Division, under the keep whole agreement, was to pay UPR when the prevailing
market price exceeded the contractual fixed price. Accordingly, at December 31,
1997, the UPFuels Division recorded a reserve for the fair value of the
difference between the fixed rate under the firm transportation agreements and
the estimated market rates for the period from 2004 to the end of the respective
contract periods. At December 31, 1997, the reserves, which were included in
other long-term liabilities, were $13.0 million, $5.5 million, and $7.6 million
for the Kern River, Texas Gas, and PGT agreements, respectively.

     In conjunction with the sale of the UPFuels Division to Duke Energy Field
Services, Inc. during 1998 the UPFuels Division extended the keep whole
agreement with UPR to cover a 10 year period commencing March 1, 1999 or through
the expiration of the contract, whichever is earlier. In addition, UPR retained
the transportation contract with Kern River. Accordingly, no reserves for the
Kern River and Texas Gas Agreements were recorded at December 31, 1998 or March
31, 1999 and $17.6 million was recorded at December 31, 1998 and March 31, 1999
for the PGT agreement, reflecting additional liabilities for volumes acquired in
1998, partially offset by the extension of the keep whole agreement. During
1998, $8.5 million was recorded as a change in divisional equity for the change
in the keep whole agreement. A detailed explanation of the three major long-term
firm transportation agreements are as follows:

     Under the Kern River transportation agreement which expires in 2007, the
UPFuels Division has the right to transport 75 MMcfd of gas on the Kern River
Pipeline system which extends from Opal, Wyoming, to an interconnection with the
Southern California Gas Company pipeline system in southern California. Nine
years remain on the primary term of the agreement, and the current
transportation rate is $0.69 per Mcf. Thereafter, this rate can change based on
Kern River's cost of service and upon rate regulation policies of the Federal
Energy Regulatory Commission ("FERC"). Under a 1993 ruling of the FERC, the
UPFuels Division is obligated to pay all of the fixed costs included in the
transportation rate, whether or not the UPFuels Division actually uses Kern
River's pipeline to transport gas. Those fixed costs presently amount to $0.61
per Mcf. The undiscounted amount of the nine year fixed cost commitment,
assuming no future changes in the rate, is $136 million. The 1993 FERC ruling
was issued notwithstanding a provision in the transportation agreement between
Kern River and the UPFuels Division in which the parties agreed that a portion
of the fixed costs would be paid by the UPFuels Division only if and to the
extent that the UPFuels Division uses the pipeline. In light of recent changes
in the regulatory policies of FERC, the UPFuels Division is seeking
reinstatement of the contractually agreed rate structure, but there is no
assurance that such efforts will be successful.

     The UPFuels Division is a party to an additional agreement under which it
may acquire, in 2001, at its option, an additional 25 MMcfd of transportation
rights on the Kern River system beginning in 2002.

     Under the Texas Gas transportation agreement, which expires in 2008, the
UPFuels Division has the rights to transport 90 MMcfd of gas from the UPFuels
Division's East Texas plant. The UPFuels Division is obligated to pay a fixed
transportation rate of $0.33 per Mmbtu regardless of the volumes transported
under the agreement. The undiscounted amount of this commitment is $104 million.

     Under the PGT transportation agreement, which expires in 2023, the UPFuels
Division has the rights to transport 25 MMcfd of gas from Kingsgate, British
Columbia to the California/Oregon border. The UPFuels Division is obligated to
pay a fixed transportation rate of $0.33 per Mmbtu regardless of the volumes

transported under the agreement. However, the UPFuels Division has third party
agreements that reimburse the UPFuels Division for 90 percent of the firm
transportation cost until October 2002. As part of the third party agreements,
the UPFuels Division assigned 50 percent of the firm transportation capacity.
The term for the keep whole agreement for this contract commences on November 1,
2002 and terminates on February 28, 2009. The undiscounted amount of this
commitment, net of the third party reimbursements, is $64 million.

During 1998, the UPFuels Division assumed responsibility for additional
long-term firm transportation agreements with PGT to transport gas from
Kingsgate, British Columbia to the California/Oregon border. Under the
transportation agreements, the UPFuels Division has the rights to transport 106
Mmbtu per day of which 47 Mmbtu per day will expire in October 2007 and the
balance of the contract commitment will expire in October 2023. The UPFuels
Division does have a third party agreement that recovers all the transportation
cost for 20 Mmbtu per day through June 2011.

     The UPFuels Division is a defendant in a number of lawsuits and is involved
in governmental proceedings arising in the ordinary course of business,
including contract claims, personal injury claims and environmental claims.
While management of the UPFuels Division cannot predict the outcome of such
litigation and other proceedings, management does not expect those matters to
have a materially adverse effect on the consolidated financial condition or
results of operations of the UPFuels Division.
