                            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 granted
concurrently with the offering.


                                      DUKE


     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 believe that we are one of the largest gatherers of raw natural gas,
based on wellhead volume, in North America. We are the largest producer, and we
believe that we are 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>   7

     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 from Atlantic Richfield Company, for $318.5
million, its ownership interests in a 500-mile crude oil pipeline that extends
from a marine terminal at Freeport, Texas to Cushing, Oklahoma, a 416-mile crude
oil pipeline that extends from Jal, New Mexico to Cushing, a 400-mile crude oil
pipeline that extends from West Texas to Houston, crude oil terminal facilities
in Midland, Cushing and the Houston area and receipt and delivery pipelines
centered around Midland. The transaction is contingent upon satisfaction of
regulatory requirements.


                             OUR BUSINESS STRATEGY


     We believe that we are one of the largest gatherers of raw natural gas in
North America. We are the largest producer, and we believe that we are 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
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:


          - the Combination and the sale of our common stock in the offering;


          - the Predecessor Company's acquisition of Union Pacific Fuels;

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

          - the transfer to us of the general partner of TEPPCO,


      in each case as if the transactions had occurred on January 1, 1999 for
      income statement purposes and March 31, 2000 for balance sheet purposes;
      and



     - additional financial and other data giving effect to the Union Pacific
       Fuels acquisition and the Combination, as if each had occurred on January
       1, 1995.

                   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.

(1) Includes $34.0 million of hedging losses recorded in total operating
    revenues. Duke Energy commenced risk management activities associated with
    its midstream natural gas business at the end of 1998. Activity for periods
    prior to 1999 was not significant.


(2) Includes the results of operations of Union Pacific Fuels for the nine
    months ended December 31, 1999. Union Pacific Fuels was acquired by the
    Predecessor Company on March 31, 1999.

    revenues.



(4) 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.


(5) Based on index prices from the Mont Belvieu, Texas and Conway, Kansas market
    hubs that are weighted by our component and location mix for the periods
    indicated.

(6) Based on the NYMEX Henry Hub prices for the periods indicated.


(7) We expect to have $2.1 billion of short-term indebtedness outstanding after
    the offering and expect to convert a significant portion of this short-term
    debt to long-term debt as market conditions permit. See "Management's
    Discussion and Analysis of Financial Condition and Results of
    Operations -- Liquidity and Capital Resources."

                                  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 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.



     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


                                       12
<PAGE>   15


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, or under any dividend reinvestment plan;



     - shares of our common stock issued in connection with the merger of the
       subsidiary of Phillips that holds Phillips' interest in Field Services
       LLC into our company to be completed concurrently with the completion of
       the offering; or



     - shares of our common stock or other securities convertible or
       exchangeable into shares of our common stock issued as payment of any
       part of the purchase price for businesses or assets we acquire, provided
       that any shares or securities so issued may not be transferred during the
       180-day lock-up period.



     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."


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;

                                       13
<PAGE>   16

     - 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 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

                                       14
<PAGE>   17

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 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."

                                       15
<PAGE>   18

     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 cleanup 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.

     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.
                                       16
<PAGE>   19


     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 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

                                       17
<PAGE>   20


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 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.
                                       18
<PAGE>   21


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.

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.
                                       19
<PAGE>   22

                                    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:

     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

                       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.

(1) Includes $34.0 million of hedging losses recorded in total operating
    revenues. Duke Energy commenced risk management activities associated with
    its midstream natural gas business at the end of 1998. Activity for periods
    prior to 1999 was not significant.

(2) Includes the results of operations of Union Pacific Fuels for the nine
    months ended December 31, 1999. Union Pacific Fuels was acquired by the
    Predecessor Company on March 31, 1999.


(3) Earnings per share is not presented for historical periods since the
    Predecessor Company was an indirect wholly owned subsidiary of Duke Energy.
    Pro forma earnings per share reflects outstanding shares after the
    Combination and the anticipated issuance of common stock from the offering.



(4) EBITDA consists of income from continuing operations before interest
    expense, income tax expense, and depreciation and amortization expense, less
    interest income. EBIT consists of income from continuing operations before
    interest expense and income tax expense, less interest income. Neither
    EBITDA nor EBIT is a measurement presented in accordance with generally
    accepted accounting principles. You should not consider either measure 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.


(5) Based on index prices from the Mont Belvieu and Conway market hubs that are
    weighted by our component and location mix for the periods indicated.

(6) Based on the NYMEX Henry Hub prices for the periods indicated.


(7) We expect to have $2.1 billion of short-term indebtedness outstanding after
    the offering and expect to convert a significant portion of this short-term
    debt to long-term debt as market conditions permit. See "Management's
    Discussion and Analysis of Financial Condition and Results of
    Operations -- Liquidity and Capital Resources."


(8) Includes $4.0 million of hedging gain and $46.7 million of hedging loss for
    the three months ended March 31, 1999 and 2000, respectively.

          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>   30


     The following chart 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
chart 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 chart 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 chart 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>   31

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. The acquisition of the Conoco/Mitchell assets is significant in that the
assets acquired lie adjacent to and between our current assets, providing future
integration opportunities. 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>   33

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>   34


     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>   35

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. In addition to the GAAP measures described above, we also use the
non-GAAP measure of EBITDA. EBITDA is a measure used to provide information
regarding our ability to cover fixed charges such as interest, taxes, dividends
and capital expenditures. In addition, EBITDA provides a comparable measure to
evaluate our performance relative to that of our competitors by eliminating the
capitalization structure and depreciation charges, which may vary significantly
within our industry. Although the GAAP financial statement measure of net income
or loss, in total and by segment, is indicative of our profitability, net income
does not necessarily reflect our ability to fund our fixed charges on a periodic
basis. We therefore use GAAP and non-GAAP measures in evaluating our overall
performance as well as that of our related segments. In addition, we use both
types of measures to evaluate our performance relative to other companies within
our industry.


     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,
                                       33
<PAGE>   36

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.

     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.

                                       34
<PAGE>   37

     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
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.

                                       35
<PAGE>   38

     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 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.


                                       36
<PAGE>   39

     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 bank credit facility will be permanently reduced by
the amount of such proceeds. The amount available under the bank 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 facilities 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

                                       37
<PAGE>   40

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 million 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

                                       38
<PAGE>   41

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:

     - 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

                                       39
<PAGE>   42

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:

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 believe that we are one of the largest gatherers of raw natural gas,
based on wellhead volume, in North America. We are the largest producer, and we
believe that we are 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
                                       41
<PAGE>   44

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 from Atlantic Richfield Company, for $318.5
million, its ownership interests in a 500-mile crude oil pipeline that extends
from a marine terminal at Freeport, Texas to Cushing, Oklahoma, a 416-mile crude
oil pipeline that extends from Jal, New Mexico to Cushing, a 400-mile crude oil
pipeline that extends from West Texas to Houston, crude oil terminal facilities
in Midland, Cushing and the Houston area and receipt and delivery pipelines
centered around Midland. 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, according to the Oil and Gas Journal's "1999
Worldwide Gas Processing Report," we are among the three largest midstream
natural gas companies based on volumes of natural gas gathered and processed or
volumes of NGLs produced) 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 believe that we are one of the largest gatherers of raw natural gas,
based on wellhead volume, in North America. We are the largest producer, and we
believe that we are one of the largest marketers, of

                                       42
<PAGE>   45


NGLs 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 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

                                       43
<PAGE>   46

     - 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.


     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, according to the Oil and Gas Journal's "1999 Worldwide
Gas Processing Report," we are among the three largest midstream natural gas
companies based on volumes of natural gas gathered and processed or volumes of
NGLs produced.


     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 EIA 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

                                       44
<PAGE>   47

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 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

                                       45
<PAGE>   48

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 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.

(1) Excludes approximately 7,500 barrels per day processed at third party plants
    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.

                                       46
<PAGE>   49

     - 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 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

                                       47
<PAGE>   50

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 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
                                       48
<PAGE>   51

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.

     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.
                                       49
<PAGE>   52

     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 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.


                                       50
<PAGE>   53

     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 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 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;

     - 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.

                                       52
<PAGE>   55

     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 from Atlantic Richfield Company, for $318.5
million, its ownership interests in a 500-mile crude oil pipeline that extends
from a marine terminal at Freeport, Texas to Cushing, Oklahoma, a 416-mile crude
oil pipeline that extends from Jal, New Mexico to Cushing, a 400-mile crude oil
pipeline that extends from West Texas to Houston, crude oil terminal facilities
in Midland, Cushing and the Houston area and receipt and delivery pipelines
centered around Midland. 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

                                       53
<PAGE>   56

     - 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.

     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;

                                       54
<PAGE>   57

     - 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 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. This could increase our cost of regulatory compliance
and place us at a disadvantage in comparison to companies that are not required
to satisfy the reporting requirements. 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. We


                                       55
<PAGE>   58


currently believe that Order No. 639 and the related reporting requirements will
not have a material adverse effect on our existing business activities.


     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.

     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 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

                                       57
<PAGE>   60

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 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
                                       58
<PAGE>   61

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.


     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

                                       59
<PAGE>   62

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 May 15, 2000, we had approximately 2,600 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.

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.


                                       65
<PAGE>   68


     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


                                       66
<PAGE>   69

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 and
increase the number of shares of common stock reserved for issuance under the
plan.


     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. The acquisition
of the Conoco/Mitchell assets is significant in that the assets acquired lie
adjacent to and between our current assets, providing future integration
opportunities. 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.


                                       68
<PAGE>   71

     LICENSE AGREEMENT


     Duke Energy has licensed to us a non-exclusive right to use the phrase
"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 raw natural gas and other
petroleum products 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 historically provided the Predecessor Company with various
support services, including information technology services, accounting, legal,
insurance, payroll, cash management, risk management

                                       69
<PAGE>   72


and welfare benefits services. Duke Energy 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.

                                       70
<PAGE>   73


     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.

SHAREHOLDERS AGREEMENT


     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
                                       71
<PAGE>   74


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

                                       72
<PAGE>   75

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.


                                       73
<PAGE>   76

                             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.


                                       75
<PAGE>   78

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.

                                       76
<PAGE>   79


     If a business opportunity 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.

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.

                        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 and for a period of 180 days after the date
of this prospectus, we, Duke Energy and Phillips have agreed not to directly or
indirectly, without the prior written consent of Morgan Stanley & Co.
Incorporated:


     - 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 dispose of, directly or

                                       79
<PAGE>   82

       indirectly, any shares of common stock or securities convertible into or
       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
       stock whether any such swap or transaction is to be settled by delivery
       of common stock or other securities, in cash or otherwise.

As exceptions to these restrictions, we may:

     - issue shares of our common stock or grant options to purchase shares of
       common stock in connection with our existing employee benefit plans;


     - issue shares of our common stock in connection with any non-employee
       director stock plan or dividend reinvestment plan;



     - issue shares of our common stock in connection with the merger of the
       subsidiary of Phillips that indirectly holds Phillips' interest in Field
       Services LLC into our company to be completed concurrently with the
       completion of the offering; and


     - issue shares of our common stock or securities convertible or
       exchangeable into our common stock as payment of any part of the purchase
       price for businesses or assets we acquire; however, shares issued in this
       manner may not be transferred during the 180-day lock-up period.

2000 LONG-TERM INCENTIVE PLAN


     After the offering, we intend to file a registration statement covering the
sale of up to 4,000,000 shares of common stock which have been reserved for
issuance under our long-term incentive plan thus permitting resale of these
shares by non-affiliates in the public market without restriction.


                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.

                                       80
<PAGE>   83

     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 rate of 30% of the gross amount, or such lower rate
prescribed by an applicable income tax treaty, unless the dividends are
effectively connected with a trade or business carried on by (or, under an
applicable income tax treaty, attributable to a permanent establishment of) the
Non-U.S. Holder in the United States. Dividends that are so effectively
connected (or attributable) generally will not be subject to U.S. withholding
tax if the Non-U.S. Holder files Internal Revenue Service Form 4224 or W-8ECI
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. 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
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; 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 provides otherwise, and therefore may be subject to U.S. federal estate
tax.

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 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 United States 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 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 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.

     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 certain 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 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 or the grant of options to purchase common stock pursuant to
       employee benefit plans in existence as of the date of this prospectus or
       pursuant to any non-employee director stock plan or dividend reinvestment
       plan;



     - the issuance by Duke Energy Field Services Corporation of shares of
       common stock in connection with the merger of the subsidiary of Phillips
       that indirectly holds Phillips' interest in Field Services LLC into Duke
       Energy Field Services Corporation to be completed concurrently with the
       completion of the offering;



     - the issuance by Duke Energy Field Services Corporation of shares of
       common stock or securities exchangeable or convertible into common stock
       as payment of any part of the purchase price for businesses or assets it
       acquires, so long as any shares so issued are subject to the 180-day
       lock-up period; 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

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 approximately $4.5 million.



     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 Services 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 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.

                                 (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:

   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.

                     DUKE ENERGY FIELD SERVICES CORPORATION

               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:

</TABLE>



     A .125% increase or decrease in the assumed weighted average interest rate
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.


8. The pro forma adjustment to income taxes reflects the use of the combined
   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
   follows:

                          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 bad debt reserve of $6 million was established
in the purchase price allocation associated with the UP Fuels acquisition (see
Note 2). 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 (See Note 5).

            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:

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.

(b) EBITDA consists of income from continuing operations before interest

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.

     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
million and $11.8 million in 1997, 1998 and 1999, respectively. Minimum rental
payments under the Predecessor Companies' various operating leases for the years
2000 through 2004 are $6.1, $6.0, $5.0, $5.0 and $4.3 million, respectively.
Thereafter, payments aggregate $15.4 million through 2011.

     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

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):

<TABLE>
<S>                                                           <C>
Property, plant and equipment...............................  $2,073.0
Goodwill....................................................     412.9
Deferred income taxes.......................................   (607.5)
Other assets, net...........................................      41.4
                                                              --------
          Total purchase price..............................  $1,919.8
                                                              ========
</TABLE>

     The purchase price has not yet been fully allocated to the individual
assets and liabilities acquired. The final allocation will be determined based
on independent appraisals.

     In connection with the Combination, the Company has recorded a non-interest
bearing distribution payable to Phillips of $1,219.8 million and a non-interest
bearing distribution payable to Duke Energy of $1,524.5 million.

     Working Capital Adjustments -- In connection with the Combination, Duke
Energy and Phillips each will either make contributions to Field Services LLC,
or receive distributions from Field Services LLC so that

                                      F-34

                     DUKE ENERGY FIELD SERVICES CORPORATION

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  (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. The
exchange was accounted for as a like-kind exchange. These gathering and
processing assets are considered similar productive assets. Accordingly, no gain
or loss was recognized on the exchange.


4. AGREEMENTS AND TRANSACTIONS WITH DUKE ENERGY

     Services Agreement with Duke Energy -- Effective with the Combination, the
Company entered into a services agreement with Duke Energy ("the Duke Energy
Services Agreement"). Under the Duke Energy Services Agreement, Duke Energy will
provide the Company with various staff and support services, including
information technology products and services, payroll, employee benefits,
corporate insurance, cash management, ad valorem taxes, treasury and legal
functions and shareholder services. These services will be priced on the basis
of a monthly charge approximating market prices. The Duke Energy Services

                                  (UNAUDITED)

     Transactions between Duke Energy and the Company -- Through March 31, 2000,
the Company has conducted a series of transactions with Duke Energy in which the
Company has sold a portion of its residue gas and NGLs to, purchased raw natural
gas and other petroleum products from, and provided gathering and transportation
services over its gathering systems and pipelines to, Duke Energy and its
subsidiaries at contractual prices that have approximated market prices in the
ordinary course of the Company's 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
credit agreement will be used for short-term financing requirements. The
agreement terminates on May 31, 2000, and bears interest at the Bank of America

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

                                      F-37

                                  (UNAUDITED)

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 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
group composite straight-line method over an estimated life of 20 years for most
of the assets. Plants and systems are grouped for this purpose based on their
relative similarity and the degree of physical and economic interdependence
between individual pieces of equipment. Other relatively insignificant
properties and equipment are depreciated using the straight-line method over the
estimated useful lives of the individual assets.


     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
considering all available evidence at the date of the review.



     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
with no recognition of gain or loss. Retirements or sales of equipment, whether
complete units of depreciable property or less than complete units of
depreciable property, have been infrequent and not significant to the financial
statements.

                              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
     the loss of

                    NOTES TO FINANCIAL STATEMENTS--CONTINUED

     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.

     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.

16. PROPOSED BUSINESS COMBINATION

     On December 16, 1999, Phillips and Duke Energy Corporation (Duke Energy)
announced that they had signed definitive agreements to combine the two
companies' gas gathering, processing and marketing

                              PHILLIPS GAS COMPANY

                    NOTES TO FINANCIAL STATEMENTS--CONTINUED

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.

                              PHILLIPS GAS COMPANY

                   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:

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Management of
Duke Energy Field Services
Denver, Colorado

     We have audited the accompanying combined statements of income and cash
flows of the UPFuels Division of Union Pacific Resources Group Inc. (a Utah
Corporation) for the year ended December 31, 1998 and the three-month period
ended March 31, 1999. These financial statements are the responsibility of the
UPFuels Division'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 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
principles generally accepted in the United States.

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 audit provides a reasonable basis for our opinion.

     In our opinion, such combined financial statements present fairly, in all
material respects, the combined results of operations and cash flows of the
UPFuels Division for the year ended December 31, 1997, in conformity with
generally accepted accounting principles.

                     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

               NOTES TO COMBINED FINANCIAL STATEMENTS--CONTINUED

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. In the UPFuels Division originally issued financial
statements, there was no cost allocated for these services. The UPFuels Division
management subsequently determined that $2.0 million, $2.0 million and $0.5
million for 1997, 1998 and the three months ended March 31, 1999, respectively,
should have been allocated. As a result, the accompanying financial statements
have been revised from their original presentation. 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.

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.

                                      F-64

                                UPFUELS DIVISION

               NOTES TO COMBINED FINANCIAL STATEMENTS--CONTINUED

Limits are established for each major category of risk, with exposures monitored
and managed by UPFuels 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.

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.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Section 145 of the Delaware General Corporation Law ("DGCL") provides that
a corporation may indemnify any person who was or is a party or is threatened to
be made a party to any threatened, pending or completed action, suit or
proceeding whether civil, criminal, administrative or investigative (other than
an action by or in the right of the corporation by reason of the fact that he is
or was a director, officer, employee or agent of the corporation, or is or was
serving at the request of the corporation as a director, officer, employee or
agent of another corporation, partnership, joint venture, trust or other
enterprise, against expenses (including attorneys' fees), judgments, fines and
amounts paid in settlement actually and reasonably incurred by him in connection
with such action, suit or proceeding if he acted in good faith and in a manner
he reasonably believed to be in or not opposed to the best interests of the
corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful. Section 145 further
provides that a corporation similarly may indemnify any such person serving in
any such capacity who was or is a party or is threatened to be made a party to
any threatened, pending or completed action or suit by or in the right of the
corporation to procure a judgment in its favor by reason of the fact that he is
or was a director, officer, employee or agent of the corporation or is or was
serving at the request of the corporation as a director, officer, employee or
agent of another corporation, partnership, joint venture, trust or other
enterprise, against expenses (including attorneys' fees) actually and reasonably
incurred in connection with the defense or settlement of such action or suit if
he acted in good faith and in a manner he reasonably believed to be in or not
opposed to the best interests of the corporation and except that no
indemnification shall be made in respect of any claim, issue or matter as to
which such person shall have been adjudged to be liable to the corporation
unless and only to the extent that the Delaware Court of Chancery or such other
court in which such action or suit was brought shall determine upon application
that, despite the adjudication of liability but in view of all of the
circumstances of the case, such person is fairly and reasonably entitled to
indemnity for such expenses which the Delaware Court of Chancery or such other
court shall deem proper.

     The company's certificate of incorporation and bylaws provide that
indemnification shall be provided for all current and former directors and may
be provided for all current or former officers to the fullest extent permitted
by the DGCL.

     As permitted by the DGCL, the certificate of incorporation provides that
directors of the company shall have no personal liability to the company or its
stockholders for monetary damages for breach of fiduciary duty

                                      II-1
<PAGE>   160

as a director, except (1) for any breach of the director's duty of loyalty to
the company or its stockholders, (2) for acts or omissions not in good faith or
which involve intentional misconduct or knowing violation of law, (3) under
Section 174 of the DGCL or (4) for any transaction from which a director derived
an improper personal benefit.

ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES.

     The company has not sold any securities, registered or otherwise, within
the past three years, except as set forth below.

     On December 8, 1999, the company issued 1,000 shares of its common stock to
Duke Energy Corporation ("Duke Energy") for $1,000. In so doing, the company
relied on the provisions of Section 4(2) of the Securities Act of 1933, as
amended (the "Securities Act"), in claiming exemption for the offering, sale and
delivery of such securities from registration under the Securities Act.

     On December 16, 1999, Duke Energy, Phillips Petroleum Company ("Phillips")
and Duke Energy Field Services, LLC ("Field Services LLC") entered into a
Contribution Agreement (the "Contribution Agreement") pursuant to which Duke
Energy and Phillips, on March 31, 2000, contributed their respective midstream
natural gas assets to Field Services LLC, a subsidiary of the company, in
exchange for member interests in Field Services LLC and one-time cash payments.
Upon consummation of the offering contemplated by this registration statement,
the subsidiary ("Merger Subsidiary") that indirectly holds Phillips' interest in
Field Services LLC will be merged into the company, and, as a result, the
capital stock of Merger Subsidiary, all of which is owned by Phillips, will be
converted into shares of common stock of the company and the capital stock of
the company before the merger, all of which is owned by Duke Energy, will be
converted into new shares of common stock of the company. The exact allocation
between Duke Energy and Phillips of shares of common stock of the company issued
in the merger will be determined by the average of the closing prices of the
company's common stock on the New York Stock Exchange Composite Tape on the
stock's first five trading days. In so doing, the company relied on the
provisions of Section 4(2) of the Securities Act in claiming exemption for the
offering, sale and delivery of such securities from registration under the
Securities Act.

     (B) FINANCIAL STATEMENT SCHEDULE

     No financial statement schedules are required to be included herewith or
they have been omitted because the information required to be set forth therein
is not applicable.

ITEM 17. UNDERTAKINGS.

     The Registrant hereby undertakes:

          (a) Insofar as indemnification for liabilities arising under the
     Securities Act of 1933 may be permitted to directors, officers and
     controlling persons of the Registrant pursuant to the provisions described
     in Item 14, or otherwise, the Registrant has been advised that in the
     opinion of the Securities and Exchange Commission such indemnification is
     against public policy as expressed in the Act and is, therefore,
     unenforceable. In the event that a claim for indemnification against such
     liabilities (other than the payment by the Registrant of expenses incurred
     or paid by a director, officer, or controlling person of the Registrant in
     the successful defense of any action, suit or proceeding) is asserted by
     such director, officer, or controlling person in connection with the
     securities being registered, the Registrant will, unless in the opinion of
     its counsel the matter has been settled by controlling precedent, submit to
     a court of appropriate jurisdiction the question whether such
     indemnification by it is against public policy as expressed in the Act and
     will be governed by the final adjudication of such issue.

          (b) To provide to the underwriter(s) at the closing specified in the
     underwriting agreements, certificates in such denominations and registered
     in such names as required by the underwriter(s) to permit prompt delivery
     to each purchaser.

          (c) For purpose of determining any liability under the Securities Act
     of 1933, the information omitted from the form of prospectus filed as part
     of this Registration Statement in reliance upon Rule 430A and contained in
     the form of prospectus filed by the Registrant pursuant to Rule 424(b)(1)
     or (4) or 497(h) under the Securities Act shall be deemed to be part of
     this Registration Statement as of the time it was declared effective.

          (d) For the purpose of determining any liability under the Securities
     Act of 1933, each post-effective amendment that contains a form of
     prospectus shall be deemed to be a new registration statement relating to
     the securities offered therein, and the offering of such securities at that
     time shall be deemed to be the initial bona fide offering thereof.

                           DUKE ENERGY FIELD SERVICES

                          GLOBAL UNDERWRITING AGREEMENT





MORGAN STANLEY & CO. INCORPORATED
     As representatives of the several Underwriters
     named in Schedule I hereto,
c/o Morgan Stanley & Co. Incorporated,
     1585 Broadway,
     New York, New York  10036

Dear Sirs:

         Duke Energy Field Services Corporation, a Delaware corporation (the
"Company"), proposes, subject to the terms and conditions stated herein, to sell
to the several Underwriters named in Schedule I hereto (the "Underwriters") an
aggregate of 26,300,000 shares (the "Firm Shares") and, at the election of the
Underwriters, up to 3,945,000 additional shares (the "Optional Shares") of
Common Stock (par value $.01 per share) ("Stock") of the Company (the Firm
Shares and the Optional Shares which the Underwriters elect to purchase pursuant
to Section 2 hereof are herein collectively called the "Shares").

         Morgan Stanley & Co. Incorporated ("Morgan Stanley") has agreed to
reserve up to 1,972,500 of the Shares to be purchased by it under this Agreement
for sale to the directors, officers, employees and business associates of the
Company and its principal shareholders and certain other persons (collectively,
"Participants"), as set forth in the Prospectus under the heading "Underwriters"
(the "Directed Share Program"). The Shares to be sold by Morgan Stanley and its
affiliates pursuant to the Directed Share Program are referred to hereinafter as
the "Directed Shares." Any Directed Shares not orally or otherwise confirmed for
purchase by any Participants by 11:00 p.m. Eastern time on the date on which
this Agreement is executed will be offered to the public by the Underwriters as
set forth in the Prospectus.

         1. The Company represents and warrants to, and agrees with, each of the
Underwriters that:

                  (a) A registration statement in respect of the Firm Shares and
         the Optional Shares has been filed on Form S-1 with the Securities and
         Exchange Commission (the "Commission"); such registration statement and
         any post-effective amendment thereto, each in the form heretofore
         delivered to you, and excluding exhibits thereto but including all
         documents incorporated by reference in the prospectus contained
         therein, for each of the other Underwriters, have been declared
         effective by the Commission in such form; no other document with
         respect to such registration statement or document incorporated by
         reference therein has heretofore been filed with the Commission which
         has not been


<PAGE>   2

         delivered to you; and no stop order suspending the effectiveness of
         such registration statement has been issued and no proceeding for that
         purpose has been initiated or threatened by the Commission (any
         preliminary prospectus included in such effective registration
         statement or filed with the Commission pursuant to Rule 424(a) of the
         rules and regulations of the Commission under the Securities Act of
         1933, as amended (the "Act"), being hereinafter called a "Preliminary
         Prospectus"; the various parts of such registration statement,
         including all exhibits thereto and including the information contained
         in the form of final prospectus filed with the Commission pursuant to
         Rule 424(b) under the Act in accordance with Section 5(a) hereof and
         deemed by virtue of Rule 430A under the Act to be part of the
         registration statement at the time it was declared effective, being
         hereinafter called the "Registration Statement"; and such final
         prospectus, in the form first filed pursuant to Rule 424(b) under the
         Act being hereinafter called the "Prospectus"). If the Company has
         filed an abbreviated registration statement to register additional
         Shares pursuant to Rule 462(b) under the Act (the "Rule 462
         Registration Statement"), then any reference herein to the term
         "Registration Statement" shall be deemed to include such Rule 462
         Registration Statement.

                  (b) No order preventing or suspending the use of any
         Preliminary Prospectus has been issued by the Commission, and each
         Preliminary Prospectus, at the time of filing thereof, conformed in all
         material respects to the requirements of the Act and the rules and
         regulations of the Commission thereunder, and did not contain an untrue
         statement of a material fact or omit to state a material fact required
         to be stated therein or necessary to make the statements therein, in
         the light of the circumstances under which they were made, not
         misleading; except that this representation and warranty shall not
         apply to any statements or omissions made in reliance upon and in
         conformity with information relating to the Underwriters furnished in
         writing to the Company by an Underwriter through you expressly for use
         therein.

                  (c) The Registration Statement conforms and the Prospectus
         will conform in all material respects to the requirements of the Act
         and the rules and regulations of the Commission thereunder, and the
         Registration Statement and the Preliminary Prospectus do not and the
         Prospectus will not include any untrue statement of a material fact or
         omit to state any material fact required to be stated therein or
         necessary to make the statements therein not misleading, except that
         this representation and warranty shall not apply to statements or
         omissions made in any such document in reliance upon and in conformity
         with information relating to the Underwriters furnished in writing to
         the Company by an Underwriter through you expressly for use therein.

                  (d) This Agreement has been duly authorized, executed and
         delivered by the Company. The compliance by the Company with all of the
         provisions of this Agreement and the consummation of the transactions
         herein contemplated will not conflict with or result in a breach or
         violation of any of the terms or provisions of, or constitute a default
         under, any indenture, mortgage, deed of trust,

                                       -2-

         loan agreement or other agreement or instrument to which the Company or
         any entity in which the Company owns at least 50% of the capital stock
         or other interests or voting securities or voting interests (each such
         entity, a "subsidiary") is a party or by which the Company or any of
         its subsidiaries is bound or to which any of the property or assets of
         the Company or any of its subsidiaries is subject, in each case that is
         material to the Company and its subsidiaries taken as a whole; nor will
         such action result in any violation of the provisions of the
         Certificate of Incorporation or By-Laws of the Company or similar
         organizational documents of any of its subsidiaries or any statute or
         any order, rule or regulation of any court or governmental agency or
         body having jurisdiction over the Company or any of its properties; and
         no consent, approval, authorization, order, registration or
         qualification of or with any such court or governmental agency or body
         is required for the consummation by the Company of the transactions
         contemplated by this Agreement, except the registration under the Act
         of the Shares and such consents, approvals, authorizations,
         registrations or qualifications as may be required under state or
         foreign securities or Blue Sky laws in connection with the purchase and
         distribution of the Shares by the Underwriters.

                  (e) The Company has been duly incorporated, is validly
         existing as a corporation in good standing under the laws of the
         jurisdiction of its incorporation, has the corporate power and
         authority to own its property and to conduct its business as described
         in the Prospectus and is duly qualified as a foreign corporation to
         transact business and is in good standing in each jurisdiction in which
         the conduct of its business or its ownership or leasing of property
         requires such qualification, except to the extent that the failure to
         be so qualified or be in good standing would not have a material
         adverse effect on the Company and its subsidiaries, taken as a whole.

                  (f) Each subsidiary has been duly incorporated, is validly
         existing as a corporation (or limited liability company, as the case
         may be) in good standing under the laws of the jurisdiction of its
         incorporation or formation, has the corporate (or limited liability
         company) power and authority to own its property and to conduct its
         business as described in the Prospectus and is duly qualified to
         transact business and is in good standing in each jurisdiction in which
         the conduct of its business or its ownership or leasing of property
         requires such qualification, except to the extent that the failure to
         be so qualified or be in good standing or to have such power and
         authority singly or in the aggregate would not have a material adverse
         effect on the Company and its subsidiaries, taken as a whole; all of
         the issued shares of capital stock (or limited liability company
         interests) of each subsidiary of the Company have been duly and validly
         authorized and issued, are fully paid and non-assessable and are owned
         directly by the Company (or if not owned directly by the Company, are
         owned by a subsidiary of the Company), free and clear of all liens,
         encumbrances, equities or claims.

                  (g) There has not occurred any material adverse change, or any
         development involving a prospective material adverse change, in the
         condition, financial or otherwise, or in the earnings, business or
         operations of the Company

                                       -3-

         and its subsidiaries, taken as a whole, from that set forth in the
         Prospectus (exclusive of any amendments or supplements thereto
         subsequent to the date of this Agreement).

                  (h) The Company and its subsidiaries (1) are in compliance
         with any and all applicable foreign, federal, state and local laws and
         regulations relating to the protection of human health and safety, the
         environment or hazardous or toxic substances or wastes, pollutants or
         contaminants ("Environmental Laws"), (2) have received all permits,
         licenses or other approvals required of them under applicable
         Environmental Laws to conduct their respective businesses and (3) are
         in compliance with all terms and conditions of any such permit, license
         or approval, except where such noncompliance with Environmental Laws,
         failure to receive required permits, licenses or other approvals or
         failure to comply with the terms and conditions of such permits,
         licenses or approvals would not, singly or in the aggregate, have a
         material adverse effect on the Company and its subsidiaries, taken as a
         whole.

                  (i) There are no costs or liabilities associated with
         Environmental Laws (including, without limitation, any capital or
         operating expenditures required for clean-up, closure of properties or
         compliance with Environmental Laws or any permit, license or approval,
         any related constraints on operating activities and any potential
         liabilities to third parties) that would, singly or in the aggregate,
         have a material adverse effect on the Company and its subsidiaries,
         taken as a whole.

                  (j) Deloitte & Touche LLP, Ernst & Young LLP and Arthur
         Andersen LLP, who have certified certain financial statements of the
         Company and its subsidiaries, are independent public accountants as
         required by the Act and the rules and regulations of the Commission
         thereunder.

                  (k) The Company and its subsidiaries have good and marketable
         title to all real property and beneficial or record title to or
         interest in all pipeline easements, rights of way, licenses and land
         use permits owned by them, except where such failure would not, singly
         or in the aggregate, have a material adverse effect on the Company and
         its subsidiaries taken as a whole, in each case free and clear of all
         liens, encumbrances and defects except (i) such as are described in the
         Prospectus and (ii) liens securing taxes and other governmental changes
         or claims of materialmen, mechanics and similar persons that are not
         yet due and payable and that do not materially affect the value of such
         property and do not materially interfere with the use made and proposed
         to be made of such property by the Company and its subsidiaries; and
         any real property and buildings held under lease by the Company and its
         subsidiaries are held by them under leases that are valid, existing and
         in full force and effect, except as described in the Prospectus or
         where the failure to be valid, existing and in full force and effect
         would not have a material adverse effect on the Company and its
         subsidiaries, taken a whole.

                  (l) Except as described in the Prospectus, the Company and its
         subsidiaries possess all certificates, authorizations and permits
         issued by the appropriate federal, state or foreign regulatory
         authorities necessary to conduct their respective businesses except
         where such failure to possess required certificates, authorizations and
         permits would not, singly or in the aggregate, have a material adverse
         effect on the Company and its subsidiaries, taken as a whole, and
         neither the Company nor any of its subsidiaries has received any notice
         of proceedings relating to the revocation or modification of any such
         certificate, authorization or permit that, singly or in the aggregate,
         if the subject of an unfavorable decision, ruling or finding, would
         have a material adverse effect on the Company and its subsidiaries,
         taken as a whole.

                  (m) There are no legal or governmental proceedings pending or
         to the Company's knowledge threatened or expected to which the Company
         or any of its subsidiaries is a party or to which any of the properties
         of the Company or any of its subsidiaries is subject that are required
         to be described in the Registration Statement or the Prospectus and are
         not so described or any statutes, regulations, contracts or other
         documents that are required to be described in the Registration

         Company or any of its subsidiaries exists, except as described in the
         Prospectus, or, to the knowledge of the Company, is imminent.

                  (o) There are no contracts, agreements or understandings
         between the Company and any person granting such person the right to
         require the Company (1) to file a registration statement under the Act
         with respect to any securities of the Company (except for contacts,
         agreements or understandings described in the Registration Statement or
         the Prospectus) or (2) to require the Company to include any such

                  (p) The statements in the Prospectus under the captions
         "Relationship with Duke Energy and Phillips," "Shares Eligible for
         Future Sale" and "Description of Capital Stock", in each case insofar

         respect to such documents and proceedings and fairly summarize the
         matters referred to therein.

                  (q) When distributed together with the Canadian law supplement
         dated May 16, 2000, as it may be hereafter amended, the Prospectus and

         if applicable, are distributed in connection with the Directed Share
         Program.

                  (r) No consent, approval, authorization or order of, or
         qualification with, any governmental body or agency, other than those
         obtained, is required in connection with the offering of the Directed
         Shares in any jurisdiction where the Directed Shares are being offered.

                  (s) The Company has not offered, or caused Morgan Stanley or
         its affiliates to offer, Shares to any person pursuant to the Directed
         Share Program with the intent to unlawfully influence (1) a customer or
         supplier of the Company to alter the customer's or supplier's level or
         type of business with the Company, or (2) a trade journalist or
         publication to write or publish favorable information about the Company
         or its products.

                  (t) The Company is not a "holding company," or a
         "public-utility company," or a "subsidiary company" of a "holding
         company," as each such term is defined in the Public Utility Holding
         Company Act of 1935, as amended.

                  (u) The shares of Common Stock outstanding prior to the
         issuance of the Shares have been duly authorized and are validly
         issued, fully paid and non-assessable.

                  (v) The Shares have been duly authorized and, when issued and
         delivered in accordance with the terms of this Agreement, will be
         validly issued, fully paid and non-assessable, and the issuance of such
         Shares will not be subject to any preemptive or similar rights.

         2. Subject to the terms and conditions herein set forth, (a) the
Company agrees to sell to each of the Underwriters, and each of the Underwriters
agrees, severally and not jointly, to purchase from the Company at a purchase
price per share of $_________________ the number of Firm Shares to be purchased
by such Underwriter as set forth opposite the name of such Underwriter in
Schedule I hereto and (b) in the event and to the extent that the Underwriters
shall exercise the election to purchase Optional Shares as provided below, the
Company agrees to sell to each of the Underwriters, and each of the Underwriters
agrees, severally and not jointly, to purchase from the Company, at the purchase
price per share set forth in clause (a) of this Section 2, that portion of the
number of Optional Shares as to which such election shall have been exercised
(to be adjusted by you so as to eliminate fractional shares) determined by
multiplying such number of Optional Shares by a fraction the numerator of which
is the maximum number of Optional Shares that such Underwriter is entitled to
purchase as set forth opposite the name of such Underwriter in Schedule I hereto
and the denominator of which is the maximum number of the Optional Shares that
all of the Underwriters are entitled to purchase hereunder.

         The Company hereby grants to the Underwriters the right to purchase at
their election up to 3,945,000 Optional Shares, at the purchase price per share
set forth in the paragraph above, for the sole purpose of covering
over-allotments in the sale of the Firm Shares. Any such election to purchase
Optional Shares may be exercised by written notice from you to the Company,
given within a period of 30 calendar days after the date of this Agreement and
setting forth the aggregate number of Optional Shares to be purchased and the
date on which such Optional Shares are to be delivered, as determined by you but
in no event earlier than the First Time of Delivery (as defined in Section 4
hereof) or, unless you and the Company otherwise agree in writing, earlier than
two or later than ten business days after the date of such notice.

         3. Upon the authorization by you of the release of the Firm Shares, the
several Underwriters propose to offer the Firm Shares for sale upon the terms
and conditions set forth in the Prospectus.

         4. Certificates in definitive form for the Shares to be purchased by
each Underwriter hereunder, and in such denominations and registered in such
names as Morgan Stanley may request upon at least forty-eight hours' prior
notice to the Company, shall be delivered by or on behalf of the Company to you
for the account of such Underwriter, against payment by such Underwriter or on
its behalf of the purchase price therefor by wire transfer in immediately
available funds to an account of the Company properly identified at least 48
hours in advance, at the office of Sullivan & Cromwell, 125 Broad Street, New
York, New York 10004 or at such other place as you and the Company may
determine. The time and date of such delivery and payment shall be, with respect
to the Firm Shares, 9:30 a.m., New York City time, on [JUNE 1, 2000], or such
other time and date as you and the Company may agree upon in writing, and, with
respect to the Optional Shares, 9:30 a.m., New York City time, on the date
specified by you in the written notice given by you of the Underwriters'
election to purchase such Optional Shares, or such other time and date as you
and the Company may agree upon in writing. Such time and date for delivery of
the Firm Shares is herein called the "First Time of Delivery," such time and
date for delivery of the Optional Shares, if not the First Time of Delivery, is
herein called the "Second Time of Delivery," and each such time and date of
delivery is herein called a "Time of Delivery." Such certificates will be made
available for checking and packaging at least twenty-four hours prior to each
Time of Delivery at such office of Sullivan & Cromwell.

         5. The Company covenants and agrees with the several Underwriters that:

                  (a) Before amending or supplementing the Registration
         Statement or the Prospectus, to furnish to you a copy of each such
         proposed amendment or supplement and not to file any such proposed
         amendment or supplement to which you reasonably object, and to file
         with the Commission within the applicable period specified in Rule
         424(b) under the Act any prospectus required to be filed pursuant to
         such Rule.

                  (b) The Company will advise you promptly after it receives
         notice thereof of the institution by the Commission of any stop order
         proceedings in respect of the Registration Statement, and will use its
         best efforts to prevent the issuance of any such stop order and to
         obtain as soon as possible its withdrawal, if issued.

                  (c) If at any time when a prospectus relating to the Shares is
         required to be delivered under the Act any event occurs as a result of
         which the Prospectus as then amended or supplemented would include an
         untrue statement of a material fact, or omit to state any material fact
         necessary to make the statements therein, in the light of the
         circumstances under which they were made, not misleading, or if it is
         necessary at any time to amend the Prospectus to comply with the Act,
         the Company promptly will prepare and file with the Commission an
         amendment, supplement or an appropriate document that will correct such
         statement or omission or that will effect such compliance.

<PAGE>   8

                  (d) The Company, during the period when a prospectus relating
         to the Shares is required to be delivered under the Act, will file
         promptly all documents required to be filed with the Commission
         pursuant to Section 13 or 14 of the Exchange Act.

                  (e) The Company will make generally available to its security
         holders, in each case as soon as practicable after the close of the
         period covered thereby, an earnings statement (in form complying with
         the provisions of Section 11(a) of the Act, which need not be certified
         by independent certified public accountants unless required by the Act)
         covering a twelve-month period beginning not later than the first day
         of the Company's fiscal quarter next following the effective date of
         the Registration Statement.

                  (f) The Company will furnish to you copies of the Registration
         Statement (three of which will be signed and will include all exhibits
         other than those incorporated by reference), the Prospectus, and all
         amendments and supplements to such documents, in each case as soon as
         available and in such quantities as you reasonably request.

                  (g) The Company will arrange or cooperate in arrangements for
         the qualification of the Shares for sale under the laws of the United
         States, each State thereof, the District of Columbia and such
         jurisdictions as you reasonably designate and will continue such
         qualifications in effect so long as required for the distribution;
         provided, however, that the Company shall not be required to qualify as
         a foreign corporation or to file any general consents to service of
         process under the laws of any state where it is not now so subject.

                  (h) The Company will not, during the period beginning from the
         date hereof and continuing to and including the date 180 days after the
         date of the 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
         dispose of, directly or indirectly, any securities of the Company that
         are substantially similar to the Shares (any of the foregoing, a
         "Transfer"), including but not limited to any securities that are
         convertible into or exchangeable for or that represent the right to
         receive the Shares or any such substantially similar securities 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 such
         securities, whether or not such transaction is to be settled by the
         delivery of common stock or other securities, in cash or otherwise,
         without your prior written consent. The foregoing sentence shall not
         apply to (A) the Shares to be sold hereunder, (B) any securities of the
         Company that are substantially similar to the shares and are issued, or
         options to purchase such securities are granted, pursuant to existing
         employee benefit plans of the Company referred to in the Prospectus,
         (C) any securities that are substantially similar to the Shares and are
         issued pursuant to any non-employee director stock plan, (D) any
         securities that are issued pursuant to the merger described in the
         Prospectus and are substantially similar to the Shares or [(E) any
         securities that

                                       -8-
<PAGE>   9

         are substantially similar to the Shares or convertible into or
         exchangeable for common stock which represent payment of all or part of
         the purchase price of a business or assets the Company acquires;
         provided the Company shall take all action necessary to ensure that any
         securities issued pursuant to clause (E) will not be Transferred by the
         holder thereof for 180 days from the date of the Prospectus]. [N.B.
         Acquisition exception to be confirmed by MSDW, together with any
         applicable cap.]

                  (i) The Company will take appropriate action to prevent
         transfer of any Directed Shares that have been sold to Participants who
         are subject to the three month restriction on sale, transfer,
         assignment, pledge or hypothecation imposed by NASD Regulation, Inc.
         under its Interpretative Material 2110-1 on free-riding and withholding
         to the extent necessary to ensure compliance with the three-month
         restrictions.

                  (j) The Company will comply with all applicable securities and
         other applicable laws, rules and regulations in each jurisdiction in
         which the Directed Shares are offered in connection with the Directed

                  which the Company or any of its subsidiaries is a party that

                           (xi) The descriptions in the Registration Statement
                  and Prospectus of legal or governmental proceedings are
                  accurate and fairly present the information required to be
                  shown and such counsel does not know of any other legal or
                  governmental proceedings required to be described in the
                  Registration Statement or Prospectus that are not described as
                  required.

                           (xii) The Registration Statement as of the date of
                  effectiveness under the Act and the Prospectus as of the date
                  it was filed with, or transmitted for filing to, the
                  Commission (in each case, other than the financial statements
                  and other financial information included therein, as to which
                  no opinion need be rendered) appeared on their face to comply
                  as to form in all material respects with the requirements of
                  the Act and the rules and regulations thereunder, and nothing
                  has come to their attention that would lead them to believe
                  that the Registration Statement as of the date of
                  effectiveness under the Act (or if an amendment to such
                  Registration Statement has been filed by the Company with the
                  Commission subsequent to the effectiveness of the Registration
                  Statement, then at the time of the most recent such filing)
                  contained an untrue statement of a material fact or omitted to
                  state a material fact required to be stated therein or
                  necessary to make the statements therein not misleading or
                  that the Prospectus as of the date it was filed with, or
                  transmitted for filing to, the Commission and at such Time of
                  Delivery contained or contains an untrue statement of a
                  material fact or omitted or omits to state a material fact
                  necessary in order to make the statements therein, in the
                  light of the circumstances under which they were made, not
                  misleading.

                           (xiii) The statements made in the Prospectus under
                  the caption "Description of Capital Stock", insofar as they
                  purport to constitute summaries of the terms of the Stock,
                  under the caption "Material United States Tax Consequences to
                  Non-United States Holders", insofar as they purport to
                  constitute summaries of the principal United States federal
                  income consequences to foreign holders of the Stock , and
                  under "Relationship with Duke Energy and Phillips", "Shares
                  Eligible for Future Sale" and "Underwriting" insofar as they
                  purport to constitute summaries of the legal matters and
                  documents referred to therein, are accurate in all material
                  respects.

                  In rendering such opinion, such counsel may state that they
         express no opinion as to the laws of any jurisdiction other than the
         State of Texas, the general corporation law of the State of Delaware
         and the federal securities laws of the United States.

                  (d) Martha Wyrsch, General Counsel to the Company shall have
         furnished to you her written opinion dated such Time of Delivery, in
         form and substance satisfactory to you, to the effect that:

                                      -12-
<PAGE>   13

                           (i) each of the Company and its subsidiaries is
                  validly existing as a corporation (or limited liability
                  company, as the case may be), is in good standing under the
                  laws of the jurisdiction of its incorporation, has the
                  corporate (or limited liability company) power and authority
                  to own its property and to conduct its business as described
                  in the Prospectus and is duly qualified to transact business
                  and is in good standing in each jurisdiction in which the
                  conduct of its business or its ownership or leasing of
                  property requires such qualification, except to the extent
                  that the failure to be so qualified or be in good standing
                  would not have a material adverse effect on the Company and
                  its subsidiaries, taken as a whole.

                           (ii) the performance by the Company of this Agreement
                  and the consummation of the transactions herein and therein
                  contemplated will not contravene any of the provisions or
                  constitute a default under, any indenture, mortgage, deed of
                  trust, loan agreement or other agreement or instrument to
                  which the Company or any of its subsidiaries is a party or by
                  which the Company or any of its subsidiaries is bound or to
                  which any of the property or assets of the Company or any of
                  its subsidiaries is subject, nor will such action contravene
                  any of the provisions of the Certificate of Incorporation or
                  By-Laws of any of its subsidiaries or to the best knowledge of
                  such counsel any statute or any order, rule or regulation of
                  any court or governmental agency or body having jurisdiction
                  over the Company or any of its properties.

                           (iii) the descriptions in the Registration Statement
                  and Prospectus of legal or governmental proceedings are
                  accurate and fairly present the information required to be
                  shown and such counsel does not know of any other legal or
                  governmental proceedings required to be described in the
                  Registration Statement or Prospectus that are not described as
                  required.

                  (e) At 10:00 a.m., New York City time, on the effective date
         of the Registration Statement and also at each Time of Delivery,
         Deloitte & Touche LLP and Ernst & Young LLP and Arthur Andersen LLP
         shall have furnished to you a letter or letters, dated the respective
         date of delivery thereof in form and substance satisfactory to you, to
         the effect set forth in Annex I hereto.

                  (f) Since the respective dates as of which information is
         given in the Prospectus, there shall not have been any change or any
         development involving a prospective change, in the condition, financial
         or otherwise, or in the earnings, business or operations of the Company
         and its subsidiaries, taken as a whole, from that set forth in the
         Prospectus (exclusive of any amendments or supplements thereto
         subsequent to the date of this Agreement), the effect of which is, in
         your judgment, so material and adverse as to make it, in your judgment,
         impracticable or inadvisable to proceed with the public offering or the
         delivery of the Shares being delivered at such Time of Delivery on the
         terms and in the manner contemplated in the Prospectus.

                                      -13-
<PAGE>   14

                  (g) There shall not have occurred any downgrading, nor shall
         any notice have been given of any intended or potential downgrading or
         of any review for a possible change that does not indicate the
         direction of the possible change, in the rating accorded any securities
         of the Company or Duke Capital Corporation by any "nationally
         recognized statistical rating organization," as such term is defined
         for purposes of Rule 436(g)(2) under the Securities Act.

                  (h) On or after the date hereof there shall not have occurred
         any of the following: (i) a suspension or material limitation in
         trading in securities generally or of the securities of the Company or
         Duke Energy Corporation on the New York Stock Exchange; (ii) a general
         moratorium on commercial banking activities in New York declared by
         either Federal or New York State authorities; (iii) the outbreak or
         material escalation of hostilities or the declaration by the United
         States of a national emergency or war; or (iv) any change in financial
         markets or any calamity or crisis, if the effect of any such event
         specified in these clauses (i) through (iv) in your judgment makes it
         impracticable or inadvisable to proceed with the public offering or the
         delivery of the Shares being delivered at such Time of Delivery on the
         terms and in the manner contemplated in the Prospectus.

                  (i) "Lock-up" agreements, each substantially in the form of
         Exhibit A hereto, between you and the persons listed on Schedule A
         hereto relating to sales and certain other dispositions of shares of
         Stock or certain other securities, shall have been executed and
         delivered to you.

                  (j) The Company shall have furnished or caused to be furnished
         to you at such Time of Delivery certificates of officers of the Company
         satisfactory to you as to the accuracy of the representations and
         warranties of the Company herein at and as of such Time of Delivery, as
         to the performance by the Company of all of its obligations hereunder
         to be performed at or prior to such Time of Delivery, and as to such
         other matters relating to the transactions contemplated herein as you
         may reasonably request, and the Company shall have furnished or caused
         to be furnished certificates as to the matters set forth in subsections
         (a), (f), (g), (h) and (i) of this Section, and as to such other
         matters relating to the transactions contemplated herein as you may
         reasonably request.

         8. (a) The Company agrees to indemnify and hold harmless each
Underwriter and each person, if any, who controls any Underwriter within the
meaning of Section 15 of the Act or Section 20 of the Securities Exchange Act of
1934 (the "Exchange Act"), as follows:

                  (i) against any and all loss, liability, claim, damage and
         expense whatsoever arising out of any untrue statement or alleged
         untrue statement of a material fact contained in the Registration
         Statement (or any amendment thereto), or the omission or alleged
         omission therefrom of a material fact required to be stated therein or
         necessary to make the statements therein not misleading or arising out
         of any untrue statement or alleged untrue statement of a material fact
         contained in any Preliminary Prospectus, the prospectus constituting a
         part of the

                                      -14-
<PAGE>   15

         Registration Statement in the form in which it became effective or the
         Prospectus (or any amendment or supplement thereto) or the omission or
         alleged omission therefrom of a material fact necessary in order to
         make the statements therein, in the light of the circumstances under
         which they were made, not misleading;

                  (ii) against any and all loss, liability, claim, damage and
         expense whatsoever to the extent of the aggregate amount paid in
         settlement of any litigation, commenced or threatened, or of any claim
         whatsoever based upon any such untrue statement or omission or any such
         alleged untrue statement or omission, if such settlement is effected
         with the written consent of the Company; and

                  (iii) against any and all expense whatsoever reasonably
         incurred in investigating, preparing or defending against any
         litigation, commenced or threatened, or any claim whatsoever based upon
         any such untrue statement or omission, or any such alleged untrue
         statement or omission, to the extent that any such expense is not paid
         under (i) or (ii) above;

unless in each case of (i), (ii) or (iii) above such statement or omission or
such alleged statement or omission was made in reliance upon and in conformity
with the information relating to the Underwriters furnished in writing to the
Company by an Underwriter through you expressly for use in the Registration
Statement (or any amendment thereto) or such Preliminary Prospectus or the
Prospectus (or any amendment or supplement thereto).

         In no case shall the Company be liable under this indemnity agreement
with respect to any claim made against any Underwriter or any such controlling
person unless the Company shall be notified in writing of the nature of the
claim within a reasonable time after the assertion thereof, but failure so to
notify the Company shall not relieve it from any liability which it may have
otherwise than on account of this indemnity agreement. The Company shall be
entitled to participate at its own expense in the defense, or, if it so elects,
within a reasonable time after receipt of such notice, to assume the defense of
any suit brought to enforce any such claim, but if it so elects to assume the
defense, such defense shall be conducted by counsel chosen by it and approved by
the Underwriter or Underwriters or controlling person or persons, defendant or
defendants in any suit so brought, which approval shall not be unreasonably
withheld. In any such suit, any Underwriter or any such controlling person shall
have the right to employ its own counsel, but the fees and expenses of such
counsel shall be at the expense of such Underwriter or such controlling person
unless (i) the Company and such Underwriter shall have mutually agreed to the
employment of such counsel or (ii) the named parties to any such action
(including any impleaded parties) include both such Underwriter or such
controlling person and the Company and such Underwriter or such controlling
person shall have been advised by such counsel that a conflict of interest
between the Company and such Underwriter or such controlling person may arise
and for this reason it is not desirable for the same counsel to represent both
the indemnifying party and also the indemnified party (it being understood,
however, that the Company shall not, in connection with any one such action or
separate but substantially similar or related

                                      -15-
<PAGE>   16

actions in the same jurisdiction arising out of the same general allegations or
circumstances, be liable for the reasonable fees and expenses of more than one
separate firm of attorneys (in addition to any local counsel) for all such
Underwriters and all such controlling persons, which firm shall be designated in
writing by you). The Company agrees to notify you within a reasonable time of
the assertion of any claim against it, any of its officers or directors or any
person who controls the Company within the meaning of Section 15 of the Act or
Section 20 of the Exchange Act, in connection with the sale of the Shares.

         (b) Each Underwriter severally agrees to indemnify and hold harmless
the Company, each of its directors and each of the Company's officers who signed
the Registration Statement and each person, if any, who controls the Company
within the meaning of Section 15 of the Act or Section 20 of the Exchange Act,
to the same extent as the indemnity contained in subsection (a) of this Section,
but only with respect to statements or omissions made in the Registration
Statement (or any amendment thereto) or any Preliminary Prospectus or the
Prospectus (or any amendment or supplement thereto) in reliance upon and in
conformity with the information relating to the Underwriters furnished in
writing to the Company by such Underwriter through you expressly for use in the
Registration Statement (or any amendment thereto), such Preliminary Prospectus
or the Prospectus (or any amendment or supplement thereto). In case any action
shall be brought against the Company or any person so indemnified based on the
Registration Statement (or any amendment thereto) or such Preliminary Prospectus
or the Prospectus (or any amendment or supplement thereto) and in respect of
which indemnity may be sought against any Underwriter, such Underwriter shall
have the rights and duties given to the Company, and the Company and each person
so indemnified shall have the rights and duties given to the Underwriters, by
the provisions of subsection (a) of this Section.

         (c) No indemnifying party shall, without the prior written consent of
the indemnified party, effect any settlement of any pending or threatened
proceeding in respect of which any indemnified party is or could have been a
party and indemnity could have been sought hereunder by such indemnified party,
unless such settlement includes an unconditional release of such indemnified
party from all liability on claims that are the subject matter of such
proceeding.

         (d) To the extent the indemnification provided for in Sections 8(a) or
8(b) is unavailable to an indemnified party or insufficient in respect of any
losses, claims, damages or liabilities referred to therein, then each
indemnifying party under such paragraph, in lieu of indemnifying such
indemnified party thereunder, shall contribute to the amount paid or payable by
such indemnified party as a result of such losses, claims, damages or
liabilities in such proportion as is appropriate to reflect not only the
relative benefits received by the Company on the one hand and the Underwriters
on the other hand from the offering of the Shares but also the relative fault of
the Company on the one hand and of the Underwriters on the other hand in
connection with the statements or omissions that resulted in such losses,
claims, damages or liabilities, as well as any other relevant equitable
considerations. The relative benefits received by the Company on the

                                      -16-
<PAGE>   17

one hand and the Underwriters on the other hand in connection with the offering
of the Shares shall be deemed to be in the same respective proportions as the
net proceeds from the offering of the Shares (before deducting expenses)
received by the Company and the total underwriting discounts and commissions
received by the Underwriters, in each case as set forth in the table on the
cover of the Prospectus, bear to the aggregate Public Offering Price of the
Shares. The relative fault of the Company on the one hand and the Underwriters
on the other hand shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the Company or by the Underwriters and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission. The Underwriters' respective obligations to contribute
pursuant to this Section 8 are several in proportion to the respective number of
Shares they have purchased hereunder, and not joint.

         (e) The Company and the Underwriters agree that it would not be just or
equitable if contribution pursuant to this Section 8 were determined by pro rata
allocation (even if the Underwriters were treated as one entity for such
purpose) or by any other method of allocation that does not take account of the
equitable considerations referred to in Section 8(d). The amount paid or payable
by an indemnified party as a result of the losses, claims, damages and
liabilities referred to in the immediately preceding paragraph shall be deemed
to include, subject to the limitations set forth above, any legal or other
expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim. Notwithstanding the
provisions of this Section 8, no Underwriter shall be required to contribute any
amount in excess of the amount by which the total price at which the Shares
underwritten by it and distributed to the public were offered to the public
exceeds the amount of any damages that such Underwriter has otherwise been
required to pay by reason of such untrue or alleged untrue statement or omission
or alleged omission. No person guilty of fraudulent misrepresentation (within
the meaning of Section 11(f) of the Act) shall be entitled to contribution from
any person who was not guilty of such fraudulent misrepresentation. The remedies
provided for in this Section 8 are not exclusive and shall not limit any rights
or remedies which may otherwise be available to any indemnified party at law or
in equity.

         (f) The indemnity and contribution provisions contained in Sections 8
and 9 and the representations, warranties and other statements of the Company
contained in this Agreement shall remain operative and in full force and effect
regardless of (i) any termination of this Agreement, (ii) any investigation made
by or on behalf of any Underwriter or any person controlling any Underwriter or
by or on behalf of the Company, its officers or directors or any person
controlling the Company and (iii) acceptance of and payment for any of the
Shares.

         9.

         (a) The Company agrees to indemnify and hold harmless Morgan Stanley
and each person, if any, who controls Morgan Stanley within the meaning of
either Section 15 of the Act or Section 20 of the Exchange Act ("Morgan Stanley
Entities"), from and

                                      -17-
<PAGE>   18

against any and all losses, claims, damages and liabilities (including, without
limitation, any legal or other expenses reasonably incurred in connection with
defending or investigating any such action or claim) (i) caused by any untrue
statement or alleged untrue statement of a material fact contained in any
material prepared by or with the consent of the Company for distribution to
Participants in connection with the Directed Share Program, or caused by any
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading; (ii)
caused by the failure of any Participant to pay for and accept delivery of
Directed Shares that the Participant has agreed to purchase; or (iii) related
to, arising out of, or in connection with the Directed Share Program other than
losses, claims, damages or liabilities (or expenses relating thereto) that are
finally judicially determined to have resulted from the bad faith or negligence
of Morgan Stanley Entities.

         (b) In case any proceeding (including any governmental investigation)
shall be instituted involving any Morgan Stanley Entity in respect of which
indemnity may be sought pursuant to Section 9(a), the Morgan Stanley Entity
seeking indemnity shall promptly notify the Company in writing and the Company,
upon request of the Morgan Stanley Entity, shall retain counsel reasonably
satisfactory to the Morgan Stanley Entity to represent the Morgan Stanley Entity
in such proceeding and shall pay the fees and disbursements of such counsel
related to such proceeding. In any such proceeding, any Morgan Stanley Entity
shall have the right to retain its own counsel, but the fees and expenses of
such counsel shall be at the expense of such Morgan Stanley Entity unless (i)
the Company shall have agreed to the retention of such counsel or (ii) the named
parties to any such proceeding (including any impleaded parties) include both
the Company and the Morgan Stanley Entity and representation of both parties by
the same counsel would be inappropriate due to actual or potential differing
interests between them. The Company shall not, in respect of the legal expenses
of the Morgan Stanley Entities in connection with any proceeding or related
proceedings the same jurisdiction, be liable for the fees and expenses of more
than one separate firm (in addition to any local counsel) for all Morgan Stanley
Entities. Any such firm for the Morgan Stanley Entities shall be designated in
writing by Morgan Stanley. The Company shall not be liable for any settlement of
any proceeding effected without its written consent, but if settled with such
consent or if there be a final judgment for the plaintiff, the Company agrees to
indemnify the Morgan Stanley Entities from and against any loss or liability by
reason of such settlement or judgment. Notwithstanding the foregoing sentence,
if at any time a Morgan Stanley Entity shall have requested the Company to
reimburse it for fees and expenses of counsel as contemplated by the second and
third sentences of this paragraph, the Company agrees that it shall be liable
for any settlement of any proceeding effected without its written consent if (i)
such settlement is entered into more than 30 days after receipt by the Company
of the aforesaid request and (ii) the Company shall not have reimbursed the
Morgan Stanley Entity in accordance with such request prior to the date of such
settlement. The Company shall not, without the prior written consent of Morgan
Stanley, effect any settlement of any pending or threatened proceeding in
respect of which any Morgan Stanley Entity is or could have been a party and
indemnity could have been sought hereunder by such Morgan Stanley Entity, unless
such settlement includes an unconditional release of the Morgan Stanley Entities
from all liability on claims that are the subject matter of such proceeding.

                                      -18-
<PAGE>   19

         (c) To the extent the indemnification provided for in Section 9(a) is
unavailable to a Morgan Stanley Entity or insufficient in respect of any losses,
claims, damages or liabilities referred to therein, then the Company, in lieu of
indemnifying the Morgan Stanley Entity thereunder, shall contribute to the
amount paid or payable by the Morgan Stanley Entity as a result of such losses,
claims, damages or liabilities in such proportion as is appropriate to reflect
not only the relative benefits received by the Company on the one hand and the
Morgan Stanley Entities on the other hand from the offering of the Directed
Shares but also the relative fault of the Company on the one hand and of the
Morgan Stanley Entities on the other hand in connection with the statements or
omissions that resulted in such losses, claims, damages or liabilities, as well
as any other relevant equitable considerations. The relative benefits received
by the Company on the one hand and of the Morgan Stanley Entities on the other
hand in connection with the offering of the Directed Shares shall be deemed to
be in the same respective proportions as the net proceeds from the offering of
the Directed Shares (before deducting expenses) and the total underwriting
discounts and commissions received by the Morgan Stanley Entities for the
Directed Shares, bear to the aggregate Public Offering Price of the Shares. If
the loss, claim, damage or liability is caused by an untrue or alleged untrue
statement of a material fact, the relative fault of the Company on the one hand
and the Morgan Stanley Entities on the other hand shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement
or the omission or alleged omission relates to information supplied by the
Company or by the Morgan Stanley Entities and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission.

         (d) The Company and the Morgan Stanley Entities agree that it would not
be just or equitable if contribution pursuant to this Section 9 were determined
by pro rata allocation (even if the Morgan Stanley Entities were treated as one
entity for such purpose) or by any other method of allocation that does not take
account of the equitable considerations referred to in Section 9(c). The amount
paid or payable by the Morgan Stanley Entities as a result of the losses,
claims, damages and liabilities referred to in the immediately preceding
paragraph shall be deemed to include, subject to the limitations set forth
above, any legal or other expenses reasonably incurred by the Morgan Stanley
Entities in connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this Section 9, no Morgan Stanley Entity shall
be required to contribute any amount in excess of the amount by which the total
price at which the Directed Shares distributed to the public were offered to the
public exceeds the amount of any damages that such Morgan Stanley Entity has
otherwise been required to pay by reason of such untrue or alleged untrue
statement or omission or alleged omission. The remedies provided for in this
Section 9 are not exclusive and shall not limit any rights or remedies which may
otherwise be available to any Morgan Stanley Entity at law or in equity.

         (e) The indemnity and contribution provisions contained in this Section
9 shall remain operative and in full force and effect regardless of (i) any
termination of this Agreement, (ii) any investigation made by or on behalf of
any Morgan Stanley Entity or the Company, its officers or directors or any
person controlling the Company and (iii) acceptance of and payment for any of
the Directed Shares.

         10. The Agreement shall become effective upon the execution and
delivery hereof by the parties hereto.

         (a) If any Underwriter shall default in its obligation to purchase the
Shares that it has agreed to purchase hereunder at a Time of Delivery, you may
in your discretion arrange for you or another party or other parties to purchase
such Shares on the terms contained herein. If within thirty-six hours after such
default by any Underwriter, you notify the Company that you have so arranged for
the purchase of such Shares, you shall have the right to postpone such Time of
Delivery for a period of not more than seven days, in order to effect whatever
changes may thereby be made necessary in the Registration Statement or the
Prospectus, or in any other documents or arrangements, and the Company agrees to
file promptly any amendments to the Registration Statement or the Prospectus
that may be required. The term "Underwriter" as used in this Agreement shall
include any person substituted under this Section with like effect as if such
person had originally been a party to this Agreement with respect to such
Shares.

         (b) If, after giving effect to any arrangements for the purchase of the
Shares of a defaulting Underwriter or Underwriters as provided in subsection (a)
above, the aggregate number of such Shares that remains unpurchased does not
exceed 10% of the aggregate number of all the Shares to be purchased at such
Time of Delivery, then the Company shall have the right to require each
non-defaulting Underwriter to purchase the number of Shares that such
Underwriter agreed to purchase hereunder at such Time of Delivery and, in
addition, to require each non-defaulting Underwriter to purchase its pro rata
share (based on the number of Shares that such Underwriter agreed to purchase
hereunder) of the Shares of such defaulting Underwriter or Underwriters for
which such arrangements have not been made; but nothing herein shall relieve a
defaulting Underwriter from liability for its default.

         (c) If, after giving effect to any arrangements for the purchase of the
Shares of a defaulting Underwriter or Underwriters by you as provided in
subsection (a) above, the aggregate number of such Shares that remains
unpurchased exceeds 10% of the aggregate number of all the Shares to be
purchased at such Time of Delivery, or if the Company shall not exercise the
right described in subsection (b) above to require non-defaulting Underwriters
to purchase Shares of a defaulting Underwriter or Underwriters, then this
Agreement (or, with respect to the Second Time of Delivery, the obligations of
the Underwriters to purchase and of the Company to sell the Optional Shares)
shall thereupon terminate, without liability on the part of any non-defaulting
Underwriter or the Company, except for the expenses to be borne by the Company
and the Underwriters as provided in Section 6 hereof and the indemnity agreement
in Sections 8 and 9 hereof; but nothing herein shall relieve a defaulting
Underwriter from liability for its default.

         11. If this Agreement shall be terminated pursuant to Section 10
hereof, the Company shall not be under any liability to any Underwriter except
as provided in Section 6, Section 8 and Section 9 hereof; but, if for any other
reason any Shares are not delivered by or on behalf of the Company as provided
herein, the Company will reimburse the Underwriters through you for all
out-of-pocket expenses approved in writing by you, including fees and
disbursements of counsel, reasonably incurred by the

                                      -20-
<PAGE>   21

Underwriters in making preparations for the purchase, sale and delivery of the
Shares not so delivered, but the Company shall then be under no further
liability to any Underwriter in respect of the Shares not so delivered except as
provided in Section 6, 8 and 9 hereof.

         12. All statements, requests, notices and agreements hereunder shall be
in writing, and if to the Underwriters shall be delivered or sent by mail to you
as the representatives in care of Morgan Stanley, at 1585 Broadway, New York,
N.Y. 10036, Attention: Registration Department; and if to the Company shall be
delivered or sent by mail or facsimile transmission to the address of the
Company set forth in the Registration Statement, Attention: Secretary; provided,
however, that any notice to an Underwriter pursuant to Section 8(a) hereof shall
be delivered or sent by mail or facsimile transmission to such Underwriter at
its address or facsimile number set forth in its Underwriters' Questionnaire or
telex constituting such Questionnaire, which address or facsimile number will be
supplied to the Company by you upon request. Any such statements, requests,
notices or agreements shall take effect upon receipt thereof.

         This Agreement shall be binding upon, and inure solely to the benefit
of, the Underwriters, the Company and, to the extent provided in Sections 8 and
9 hereof, the officers and directors of the Company, and each person who
controls the Company or any Underwriter, and their respective heirs, executors,
administrators, successors and assigns, and no other person shall acquire or
have any right under or by virtue of this Agreement. No purchaser of any of the
Shares from any Underwriter shall be deemed a successor or assign by reason
merely of such purchase.

         As used herein, the term "business day" shall mean any day when the
Commission's office in Washington, D.C. is open for business.

         This Agreement shall be governed by and construed in accordance with
the laws of the State of New York.

         This Agreement may be executed by any one or more of the parties hereto
in any number of counterparts, each of which shall be deemed to be an original,
but all such counterparts shall together constitute one and the same instrument.

                                      -21-

         If the foregoing is in accordance with your understanding, please sign
and return to us eight counterparts hereof, and upon the acceptance hereof by
you, on behalf of each of the Underwriters, this letter and such acceptance
hereof shall constitute a binding agreement among each of the Underwriters and
the Company. It is understood that your acceptance of this letter on behalf of

Agreement among Underwriters the form of which shall be submitted to the Company
for examination, upon request, but without warranty on your part as to the

Morgan Stanley & Co. Incorporated
As representative of the several Underwriters named in Schedule I hereto,
c/o Morgan Stanley & Co. Incorporated
1585 Broadway, 32nd Floor
New York, NY  10036

Dear Sirs and Mesdames:

         The undersigned understands that Morgan Stanley & Co. Incorporated
("MORGAN STANLEY") proposes to enter into an Underwriting Agreement (the
"UNDERWRITING AGREEMENT") with Duke Energy Field Services Corporation, a
Delaware corporation (the "COMPANY") providing for the public offering (the
"PUBLIC OFFERING") by the several Underwriters, including Morgan Stanley (the
"UNDERWRITERS"), of an aggregate of 26,300,000 shares (the "Firm Shares") and,
at the election of the Underwriters, up to 3,945,000 additional shares (the
"Optional Shares") of Common Stock (par value $.01 per share) (the "Stock") of
the Company.

         To induce the Underwriters that may participate in the Public Offering
to continue their efforts in connection with the Public Offering, the
undersigned hereby agrees that, without the prior written consent of Morgan
Stanley on behalf of the Underwriters, it will not, during the period commencing
on the date hereof and ending 180 days after the date of the final prospectus
relating to the Public Offering (the "PROSPECTUS") (1) 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 (2) enter into any swap or other arrangement that transfers to
another, in whole or in part, any of the economic consequences of ownership of
Common Stock, whether any such transaction described in clause (1) or (2) above
is to be settled by delivery of Common Stock or such other securities, in cash
or otherwise. The foregoing sentence shall not apply to (a) the sale of any
Shares to the Underwriters pursuant to the Underwriting Agreement or (b)
transactions relating to shares of Common Stock or other securities acquired in
open market transactions after the completion of the Public Offering. In
addition, the undersigned agrees that, without the prior written consent of
Morgan Stanley on behalf of the Underwriters, it will not, during the period
commencing on the date hereof and ending 180 days after the date of the
Prospectus, make any demand for or exercise any right with respect to, the
registration of any shares of Common Stock or any security convertible into or
exercisable or exchangeable for Common Stock.

                                      -24-

         Whether or not the Public Offering actually occurs depends on a number
of factors, including market conditions. Any Public Offering will only be made
pursuant to an Underwriting Agreement, the terms of which are subject to
negotiation between the Company and the Underwriters.



                                                  Very truly yours,

Designation) increase or decrease (but not below the number of shares thereof
then outstanding);

                           (c) whether dividends, if any, shall be cumulative or
noncumulative, and, in the case of shares of any series having cumulative
dividend rights, the date or dates or method of determining the date or dates
from which dividends on the shares of such series shall be cumulative;

                           (d) the rate of any dividends (or method of
determining such dividends) payable to the holders of the shares of such series,
any conditions upon which such dividends shall be paid and the date or dates (or
the method for determining the date or dates) upon which such dividends shall be
payable;

                           (e) the price or prices (or method of determining
such price or prices) at which, the form of payment of such price or prices

another corporation or other entity) for which, the period or periods within

<PAGE>   9

securities of the same or another corporation or other entity) for which, the
period or periods within which and the terms and conditions upon which the
shares of such series shall be redeemed or purchased, in whole or in part,
pursuant to such obligation;

                           (g) the amount payable out of the assets of the
Corporation to the holders of shares of the series in the event of any voluntary
or involuntary liquidation, dissolution or winding up of the affairs of the
Corporation;

                           (h) provisions, if any, for the conversion or
exchange of the shares of such series, at any time or times at the option of the
holder or holders thereof or at the option of the Corporation or upon the
happening of a specified event or events, into shares of any other class or
classes or any other series of the same or any other class or classes of stock,
or any other security, of the Corporation, or any other corporation or other
entity, and the price or prices or rate or rates of conversion or exchange and
any adjustments applicable thereto, and all other terms and conditions upon
which such conversion or exchange may be made;

                           (i) restrictions on the issuance of shares of the
same series or of any other class or series, if any; and

                           (j) the voting rights, if any, of the holders of
shares of the series.

                  Section 4.3. Common Stock. The Common Stock shall be subject
to the express terms of the Preferred Stock and any series thereof. The holders
of shares of Common Stock shall be entitled to one vote for each such share upon
all proposals on which the holders of Common Stock are entitled to vote and the
Common Stock shall vote together as a single class. Except as otherwise provided
by law or by the resolution or resolutions adopted by the Board designating the
rights, powers and preferences of any series of Preferred Stock, the holders of
Common Stock shall have the exclusive right to vote for the members of the Board
(the "Directors") and for all other purposes. The number of authorized shares of
Preferred Stock may be increased or decreased (but not below the number of
shares thereof then outstanding) by the affirmative vote of the holders of a
majority of the outstanding Common Stock, without a vote of the holders of the
Preferred Stock, or of any series thereof, unless a vote of any such holders is
required pursuant to any Preferred Stock Designation. The Corporation shall be
entitled to treat the Person in which name any share of its stock is registered
as the owner thereof for all purposes and shall not be bound to recognize any
equitable or other claim to, or interest in, such share on the part of any other
person, whether or not the Corporation shall have notice thereof, except as
expressly provided by applicable law.

                                    ARTICLE V

                  The number, nominations, qualifications, tenure, vacancies and
removal of the Directors shall be as set forth in the Bylaws. Except and to the
extent that the Bylaws shall so require, the election of the Directors need not
be by written ballot.

                                   ARTICLE VI
                                     BYLAWS

                  In furtherance and not in limitation of the powers conferred
by statute, the Bylaws may be altered, amended or repealed and new Bylaws may be
adopted by the Board in accordance with the Bylaws.

                                   ARTICLE VII
                    AMENDMENT OF CERTIFICATE OF INCORPORATION

                  Except as set forth in Article VI, Article X and Article XII
hereof, the Corporation reserves the right at any time and from time to time to
amend, alter, change or repeal any provision contained in this Certificate of
Incorporation, and any other provisions authorized by the laws of the State of
Delaware at the time in force may be added or inserted, in the manner now or
hereafter prescribed by law; and, except as set forth in Article XI, all rights,
preferences and privileges of whatsoever nature conferred upon stockholders,
Directors or any other persons whomsoever by and pursuant to this Certificate of
Incorporation in its present form or as hereafter amended are granted subject to
the right reserved in this Article.

                                  ARTICLE VIII
                      STOCKHOLDER ACTION BY WRITTEN CONSENT

                  Prior to the first date (the "Trigger Date") upon which Duke
is not the holder of record (directly or through its subsidiaries) of a majority
of the outstanding voting stock of the Corporation entitled to vote generally in
the election of directors, any action required or permitted to be taken by the
stockholders of the Corporation may be taken without a meeting if a consent in
writing, setting forth the action so taken, is signed by the holders of
outstanding stock having not less than the minimum number of votes that would be
necessary to authorize or take such action at a meeting at which all shares
entitled to vote thereon were present and voted. On and after the Trigger Date,
any action required or permitted to be taken by the stockholders of the
Corporation must be taken at a duly held annual or special meeting of
stockholders and may not be taken by any consent in writing of such
stockholders.

                                   ARTICLE IX
                          DELAWARE ANTITAKEOVER STATUTE

                  The provisions of Section 203 of the Delaware General
Corporation Law shall not be applicable to the Corporation.

                                    ARTICLE X
                                  ANTI-DILUTION

                  At any time following the initial offering of shares of Common
Stock in a transaction registered under the Securities Act of 1933, as amended,
if the Corporation offers or issues additional shares of Common Stock or
additional shares of any other previously issued and outstanding capital stock
in a public offering, then, so long as Duke and Phillips Petroleum Company, a
Delaware corporation ("Phillips"), each owns at least 20%, directly or
indirectly, of all outstanding Common Stock, then each of Duke and Phillips
shall have the opportunity to



                                      -4-
<PAGE>   11

subscribe for and purchase such number of shares of Common Stock or such other
capital stock, as the case may be, such that the percentage ownership (direct or
indirect) of the total issued and outstanding Common Stock or such other capital
stock, as the case may be, of such party following the offering or issuance
remains equal to such party's percentage ownership (direct or indirect) of the
issued and outstanding Common Stock or such other capital stock, as the case may
be, immediately prior to the offering or issuance; provided, however, that
neither Duke nor Phillips shall have the right or opportunity hereunder to
purchase any additional Common Stock in connection with the issuance by the
Corporation of any Common Stock or options, warrants or other similar securities
in respect of Common Stock pursuant to a compensation or benefit plan or program
for officers or employees of the Corporation that has been approved by the Board
in accordance with the Bylaws. So long as Duke and Phillips each owns at least
20%, directly or indirectly, of all outstanding Common Stock, then any proposed
amendment to this Article X shall require the consent of Duke and Phillips.

                                   ARTICLE XI
                       LIMITED LIABILITY; INDEMNIFICATION

                  Section 11.1. Limited Liability of Directors. A Director shall
not be personally liable to the Corporation or its stockholders for monetary
damages for breach of fiduciary duty as a Director, except, if required by the
DGCL, as amended from time to time, for liability (a) for any breach of the
Director's duty of loyalty to the Corporation or its stockholders, (b) for acts
or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (c) under Section 174 of the DGCL or (d) for any
transaction from which the Director derived an improper personal benefit.
Neither the amendment nor repeal of this Section 11.1 shall eliminate or reduce
the effect of this Section 11.1 in respect of any matter occurring, or any cause
of action, suit or claim that, but for this Section 11.1, would accrue or arise,
prior to such amendment or repeal.

                  Section 11.2. Indemnification and Insurance.

                           (a) Right to Indemnification. Each person who was or
is made a party to or is threatened to be made a party to or is involved in any
action, suit or proceeding, whether civil, criminal, administrative or
investigative (hereinafter, a "proceeding"), by reason of the fact that such
person, or a person of whom such person is the legal representative, is or was a
Director or officer of the Corporation or is or was serving at the request of
the Corporation as a Director, officer, employee or agent of another corporation
or of a partnership, joint venture, trust or other enterprise, including service
with respect to employee benefit plans, whether the basis of such proceeding is
alleged action in an official capacity as a Director, officer, employee or agent
or in any other capacity while serving as a Director, officer, employee or
agent, shall be indemnified and held harmless by the Corporation to the fullest
extent authorized by the DGCL, as the same exists or may hereafter be amended
(but, in the case of any such amendment, to the fullest extent permitted by law,
only to the extent that such amendment permits the Corporation to provide
broader indemnification rights than said law permitted the Corporation to
provide prior to such amendment), against all expense, liability and loss
(including, without limitation, attorneys' fees, judgments, fines, amounts paid
or to be paid in settlement and excise taxes or penalties arising under the
Employment Retirement Income Security Act of 1974, as in effect from time to
time) reasonably incurred or suffered by such person in connection therewith,
and



                                      -5-
<PAGE>   12

such indemnification shall continue as to a person who has ceased to be a
Director, officer, employee or agent and shall inure to the benefit of such
person's heirs, executors and administrators; provided, however, that, except as
provided in paragraph (b) hereof, the Corporation shall indemnify any such
person seeking indemnification in connection with a proceeding (or part thereof)
initiated by such person only if such proceeding (or part thereof) was
authorized by the Board. The right to indemnification conferred in this Section
11.2 shall be a contract right and shall include the right to have the
Corporation pay the expenses incurred in defending any such proceeding in
advance of its final disposition, any advance payments to be paid by the
Corporation within 20 calendar days after the receipt by the Corporation of a
statement or statements from the claimant requesting such advance or advances
from time to time; provided, however, that, if and to the extent the DGCL
requires, the payment of such expenses incurred by a Director or officer in such
person's capacity as a Director or officer (and not in any other capacity in
which service was or is rendered by such person while a Director or officer
including, without limitation, service to an employee benefit plan) in advance
of the final disposition of a proceeding shall be made only upon delivery to the
Corporation of an undertaking, by or on behalf of such Director or officer, to
repay all amounts so advanced if it shall ultimately be determined that such
Director or officer is not entitled to be indemnified under this Section 11.2 or
otherwise. The Corporation may, to the extent authorized from time to time by
the Board, grant rights to indemnification, and rights to have the Corporation
pay the expenses incurred in defending any proceeding in advance of its final
disposition, to any employee or agent of the Corporation to the fullest extent
of the provisions of this Article XI with respect to the indemnification and
advancement of expenses of Directors and officers of the Corporation.

                           (b) Right of Claimant to Bring Suit. If a claim under
paragraph (a) of this Section is not paid in full by the Corporation within 30
calendar days after a written claim has been received by the Corporation, the
claimant may at any time thereafter bring suit against the Corporation to
recover the unpaid amount of the claim and, if successful in whole or in part,
the claimant shall be entitled to be paid also the expense of prosecuting such
claim. It shall be a defense to any such action (other than an action brought to
enforce a claim for expenses incurred in defending any proceeding in advance of
its final disposition where the required undertaking, if any is required, has
been tendered to the Corporation) that the claimant has not met the standard of
conduct which makes it permissible under the DGCL for the Corporation to
indemnify the claimant for the amount claimed, but the burden of proving such
defense shall be on the Corporation. Neither the failure of the Corporation
(including its Board, independent legal counsel or its stockholders) to have
made a determination prior to the circumstances that the claimant has met the
applicable standard of conduct set forth in the DGCL, nor an actual
determination by the Corporation (including its Board, independent legal counsel
or its stockholders) that the claimant has not met such applicable standard of
conduct, shall be a defense to the action or create a presumption that the
claimant has not met the applicable standard of conduct.

                           (c) Non-Exclusivity of Rights. The right to
indemnification and the payment of expenses incurred in defending a proceeding
in advance of its final disposition conferred in this Section 11.2 shall not be
exclusive of any other right which any person may have or hereafter acquire
under any statute, provision of the Certificate of Incorporation, Bylaw,
agreement, vote of stockholders or disinterested Directors or otherwise. No
repeal or



                                      -6-
<PAGE>   13

modification of this Article XI shall in any way diminish or adversely affect
the rights of any Director, officer, employee or agent of the Corporation
hereunder in respect of any occurrence or matter arising prior to any such
repeal or modification.

                           (d) Insurance. The Corporation may maintain
insurance, at its expense, to protect itself and any Director, officer, employee
or agent of the Corporation or another corporation, partnership, joint venture,
trust or other enterprise against any such expense, liability or loss, whether
or not the Corporation would have the power to indemnify such person against
such expense, liability or loss under the DGCL.

                           (e) Severability. If any provision or provisions of
this Article XI shall be held to be invalid, illegal or unenforceable for any
reason whatsoever: (i) the validity, legality and enforceability of the
remaining provisions of this Article XI (including, without limitation, each
portion of any paragraph of this Article XI containing any such provision held
to be invalid, illegal or unenforceable, that is not itself held to be invalid,
illegal or unenforceable) shall not in any way be affected or impaired thereby;
and (ii) to the fullest extent possible, the provisions of this Article XI
(including, without limitation, each such portion of any paragraph of this
Article XI containing any such provision held to be invalid, illegal or
unenforceable) shall be construed so as to give effect to the intent manifested
by the provision or provisions held invalid, illegal or unenforceable.

                                   ARTICLE XII
                        BUSINESS OPPORTUNITIES AGREEMENT

                  Section 12.1. Scope of Business of the Corporation and its
Subsidiaries. The Corporation hereby renounces any interest or expectancy in any
business opportunity, transaction or other matter (each, a "Business Activity")
in which Duke engages or seeks to engage that does not consist exclusively of
the Designated Business.

                  Section 12.2. Corporate Opportunities.

                           (a) In recognition that Duke is currently (at least
indirectly), and in anticipation that Duke will remain, a substantial
stockholder of the Corporation, and in anticipation that the Corporation and
Duke may engage in the same or similar activities or lines of business and have
an interest in the same or similar areas of business, and in recognition of the
benefits to be derived by the Corporation through its continued contractual,
corporate and business relations with Duke (including services of employees,
officers and directors of Duke as Directors and officers of the Corporation),
the provisions of this Article XII are set forth to regulate and define the
conduct of certain affairs of the Corporation as they may involve Duke and its
employees, officers and directors, and the powers, rights, duties, liabilities,
interests and expectancies of the Corporation in connection therewith.

                           (b) Duke shall have the right to engage (and shall
have no duty to refrain from engaging) in the same or similar activities or
lines of business as the Corporation, and the Corporation shall not be deemed to
have any interest or expectancy, and hereby renounces any interest or
expectancy, in any Business Activity, provided that such Business Activity is
conducted by Duke in accordance with the standards set forth in Section 12.3
hereof.



                                      -7-
<PAGE>   14

Neither Duke nor any employee, officer, director or agent thereof shall be
liable to the Corporation or its stockholders for breach of any fiduciary or
other duty by reason of any such Business Activity of Duke or of such person's
participation therein. In the event that Duke acquires knowledge of a potential
Business Activity, unless such Business Activity is pursued in violation of the
standards set forth in Section 12.3 hereof, Duke shall have no duty to
communicate or offer to the Corporation the opportunity to participate in such
Business Activity and shall not be liable to the Corporation or its stockholders
for breach of any fiduciary duty as a stockholder of the Corporation by reason
of the fact that Duke conducts, pursues or acquires such Business Activity for
itself, directs such Business Activity to another Person or does not communicate
information regarding such Business Activity to the Corporation, and no officer,
director, employee or other agent of Duke who serves as a Director or officer of
the Corporation or of any subsidiary of the Corporation shall have any duty to
communicate or offer the opportunity to participate in such Business Activity to
the Corporation or any liability to the Corporation or its stockholders for
breach of any fiduciary duty as a Director or officer of the Corporation by
reason of the fact that Duke conducts, pursues or acquires such Business
Activity for itself, directs such Business Activity to another Person or does
not communicate information regarding such Business Activity to the Corporation.

                  Section 12.3. Standards for Separate Conduct of Business. In
the event that Duke or any Director or officer of the Corporation who is also a
director, officer, employee or agent of Duke acquires knowledge of a potential
Business Activity, Duke, or any such person on behalf of Duke, may pursue such
Business Activity, and such pursuit shall be in accordance with the standards
set forth in this Section 12.3, if (i) such knowledge was acquired by Duke or
any such person other than through disclosure of information by or on behalf of
a Director, officer, employee or agent of the Corporation in or during the
course of such person's relationship with the Corporation and other than solely
in, and as a direct result of, such person's service as a Director or officer of
the Corporation (it being understood that if the opportunity to pursue such
Business Activity is separately identified by Duke or one of its officers,
directors, employees or agents or separately presented to Duke or one of its
officers, directors, employees or agents, Duke, or any such officer, director,
employee or agent on behalf of Duke, shall be free to pursue such opportunity
even if it also came to the attention of another officer, director, employee or
agent of Duke as a result of and in his or her capacity as a Director or officer
of the Corporation), and (ii) such Business Activity is developed and pursued
solely through the use of personnel and assets of Duke (including such person in
his or her capacity as a director, officer, employee or agent of Duke). The
Corporation shall renounce any interest or expectancy in any Business Activity
that is conducted by Duke or its officers, directors, employees or agents on
behalf of Duke in accordance with the foregoing standards. Nothing in this
Article XII shall allow any Director designated by Duke to pursue a Business
Activity in the Designated Business solely for his or her personal benefit (as
opposed to for the benefit of Duke).

                  Section 12.4. Consent. Any Person purchasing or otherwise
acquiring any interest in shares of the capital stock of the Corporation shall
be deemed to have consented to these provisions.

                           AMENDED AND RESTATED BYLAWS
                                       OF
                     DUKE ENERGY FIELD SERVICES CORPORATION


                  The original Bylaws of Duke Energy Field Services Corporation
(formerly known as DEFS Holding Corp.) (the "Corporation") were adopted by the
board of directors of the Corporation (the "Board") on December 8, 1999.

                  These Amended and Restated Bylaws have been declared advisable
by the Board, duly adopted by the stockholders of the Corporation and duly
executed and acknowledged by the officers of the Corporation in accordance with
Section 109 of the General Corporation Law of the State of Delaware ("DGCL").

                  The text of the Bylaws of the Corporation is hereby amended
and restated to read in its entirety as follows:

                                   ARTICLE I
                               OFFICES AND RECORDS

                  The Corporation shall maintain a registered office in Delaware
and may maintain such other offices and keep its books, documents and records at
such places within or without Delaware as may, from time to time, be designated
by the Board.

                                   ARTICLE II
                                  STOCKHOLDERS

                  Section 2.1. Annual Meeting. The annual meeting of the
stockholders of the Corporation shall be held on such date and at such time as
may be fixed by resolution of the Board.

                  Section 2.2. Special Meeting. Except as otherwise required by
law and subject to the rights of the holders of any class or series of stock
having a preference over the Common Stock, as defined in the Certificate of
Incorporation of the Corporation (the "Certificate of Incorporation"), as to
dividends or upon liquidation, special meetings of the stockholders of the
Corporation for any purpose or purposes may be called only by:

                  (a) the Board pursuant to a resolution stating the purpose or
purposes thereof approved by a majority of the Board, or

                  (b) the Chairman of the Board.

No business other than that stated in the notice shall be transacted at any
special meeting.

                  Section 2.3. Place of Meeting. The Board or the Chairman of
the Board, as the case may be, may designate the place of meeting for any annual
meeting or for any special meeting of the stockholders. If no designation is so
made, the place of meeting shall be the principal office of the Corporation.

                  Section 2.4. Notice of Meeting. Written or printed notice,
stating the place, day and hour of the meeting and, in the case of a special
meeting, the purpose or purposes for which the meeting is called, shall be
delivered by the Corporation not less than ten calendar days nor more than 60
calendar days before the date of the meeting, either personally or by mail, to
each stockholder of record entitled to vote at such meeting. Holders of
Preferred Stock, as defined in the Certificate of Incorporation, shall not be
entitled to receive notice of any meeting of stockholders at which they are not
entitled to vote. If mailed, such notice shall be deemed to be delivered when
deposited in the United States mail with postage thereon prepaid, addressed to
the stockholder at such person's address as it appears on the stock transfer
books of the Corporation. Only such business shall be conducted at a special
meeting of stockholders as shall have been included in the Corporation's notice
of meeting. Meetings may be held without notice if all stockholders entitled to
vote are present, or if notice is waived by those not present in accordance with
Section 6.4 of these Bylaws. Any previously scheduled meeting of the
stockholders may be postponed, and any special meeting of the stockholders may
be canceled, by resolution of the Board upon public notice given prior to the
date previously scheduled for such meeting of stockholders.

                  Section 2.5. Quorum and Adjournment; Voting. Except as
otherwise provided by law or by the Certificate of Incorporation, the holders of
a majority of the voting power of all outstanding shares of the Corporation
entitled to vote generally in the election of Directors (as hereinafter defined)
(the "Voting Stock"), represented in person or by proxy, shall constitute a
quorum at a meeting of stockholders, except that when specified business is to
be voted on by a class or series of stock voting as a class, the holders of a
majority of the shares of such class or series shall constitute a quorum of such
class or series for the transaction of such business. The chairman of the
meeting or a majority of the shares so represented may adjourn the meeting from
time to time, whether or not there is such a quorum. No notice of the time and
place of adjourned meetings need be given except as required by law. The
stockholders present at a duly called meeting at which a quorum is present may
continue to transact business until adjournment, notwithstanding the withdrawal
of enough stockholders to leave less than a quorum.

                  Section 2.6. Proxies. At all meetings of stockholders, a
stockholder may vote by proxy executed in writing (or in such other manner
permitted by the DGCL) by the stockholder or by such person's duly authorized
attorney-in-fact.

                  Section 2.7. Notice of Stockholder Business and Nominations.

                  (a) Annual Meetings of Stockholders.

                           (i) Nominations of persons for election to the Board
and the proposal of business to be considered by the stockholders may be made at
an annual meeting of stockholders (A) pursuant to the Corporation's notice of
meeting in accordance with Section 2.4 of these Bylaws, (B) by or at the
direction of the Board, or (C) by any stockholder of the Corporation who was a
stockholder of record at the time the notice provided for in this Bylaw was
delivered, who is entitled to vote at the meeting and who complies with the
notice procedures set forth in this Bylaw.

<PAGE>   22

                           (ii) For nominations or other business to be properly
brought before an annual meeting by a stockholder pursuant to clause (C) of
Section 2.7(a)(i) hereof, the stockholder must have given timely notice thereof
in writing to the Secretary of the Corporation and such other business must
otherwise be a proper matter for stockholder action. To be timely, a
stockholder's notice shall be delivered to the Secretary at the principal
executive offices of the Corporation not later than the close of business on the
90th calendar day nor earlier than the close of business on the 120th calendar
day prior to the first anniversary of the preceding year's annual meeting;
provided, however, that in the event that the date of the annual meeting is more
than 30 calendar days before or more than 60 calendar days after such
anniversary date, notice by the stockholder to be timely must be so delivered
not earlier than the close of business on the 120th calendar day prior to such
annual meeting and not later than the close of business on the later of the 90th
calendar day prior to such annual meeting or the 10th calendar day following the
calendar day on which public announcement of the date of such meeting is first
made by the Corporation. In no event shall the public announcement of an
adjournment of an annual meeting commence a new time period for the giving of a
stockholder's notice as described above. Such stockholder's notice shall set
forth (A) as to each person whom the stockholder proposes to nominate for
election or reelection as a Director, all information relating to such person
that is required to be disclosed in solicitations of proxies for election of
Directors in an election contest, or is otherwise required, in each case
pursuant to Regulation 14A under the Securities Exchange Act of 1934, as amended
(the "Exchange Act"), and Rule 14a-11 thereunder (including such person's
written consent to being named in the proxy statement as a nominee and to
serving as a member of the Board (a "Director") if elected); (B) as to any other
business that the stockholder proposes to bring before the meeting, a brief
description of the business desired to be brought before the meeting, the
reasons for conducting such business at the meeting and any material interest in
such business of such stockholder and the beneficial owner, if any, on whose
behalf the proposal is made; and (C) as to the stockholder giving the notice and
the beneficial owner, if any, on whose behalf the nomination or proposal is
made, (1) the name and address of such stockholder, as they appear on the
Corporation's books, and of such beneficial owner and (2) the class and number
of shares of the Corporation which are owned beneficially and of record by such
stockholder and such beneficial owner.

                           (iii) Notwithstanding anything in the second sentence
of paragraph (a)(ii) of this Bylaw to the contrary, in the event that the number
of Directors to be elected to the Board is increased and there is no public
announcement by the Corporation naming all of the nominees for Director or
specifying the size of the increased Board at least 100 calendar days prior to
the first anniversary of the preceding year's annual meeting, a stockholder's
notice required by this Bylaw shall also be considered timely, but only with
respect to nominees for any new positions created by such increase, if it shall
be delivered to the Secretary at the principal executive offices of the
Corporation not later than the close of business on the tenth calendar day
following the day on which such public announcement is first made by the
Corporation.

                  (b) Special Meetings of the Stockholders. Only such business
shall be conducted at a special meeting of stockholders as shall have been
brought before the meeting pursuant to the Corporation's notice of meeting under
Section 2.4 of these Bylaws. Nominations of persons for election to the Board
may be made at a special meeting of stockholders at which Directors are to be
elected pursuant to the Corporation's notice of meeting (i) by or at the
direction of the Board, (ii) provided that the Board has determined that
Directors shall be elected



                                      -3-
<PAGE>   23

at such meeting, by any stockholder of the Corporation who is a stockholder of
record at the time of giving of notice provided for in this Bylaw, who shall be
entitled to vote at the meeting and who complies with the notice procedures set
forth in this Bylaw. In the event the Corporation calls a special meeting of
stockholders for the purpose of electing one or more Directors to the Board, any
stockholder may nominate a person or persons (as the case may be) for election
to such position(s) as specified in the Corporation's notice of meeting pursuant
to clause (ii) if the stockholder's notice required by paragraph (a)(ii) of this
Bylaw shall be delivered to the Secretary at the principal executive offices of
the Corporation not earlier than the close of business on the 120th calendar day
prior to such special meeting and not later than the close of business on the
later of the 90th calendar day prior to such special meeting or the tenth
calendar day following the day on which public announcement is first made of the
date of the special meeting and of the nominees proposed by the Board to be
elected at such meeting. In no event shall the public announcement of an
adjournment of a special meeting commence a new time period for the giving of a
stockholder's notice as described above.

                  (c) General.

                           (i) Only such persons who are nominated in accordance
with the procedures set forth in this Bylaw shall be eligible to serve as
Directors and only such business shall be conducted at a meeting of stockholders
as shall have been brought before the meeting in accordance with the procedures
set forth in this Bylaw. Except as otherwise provided by law, the Certificate of
Incorporation or these Bylaws, the chairman of the meeting shall have the power
and duty to determine whether a nomination or any business proposed to be
brought before the meeting was made or proposed, as the case may be, in
accordance with the procedures set forth in this Bylaw and, if any proposed
nomination or business in not in compliance with this Bylaw, to declare that
such defective proposal or nomination shall be disregarded.

                           (ii) For purposes of this Bylaw, "public
announcement" shall mean disclosure in a press release reported by the Dow Jones
News Service, Associated Press or comparable national news service or in a
document publicly filed by the Corporation with the Securities and Exchange
Commission pursuant to Section 13, 14 or 15(d) of the Exchange Act.

                           (iii) Notwithstanding the foregoing provisions of
this Bylaw, a stockholder shall also comply with all applicable requirements of
the Exchange Act and the rules and regulations thereunder with respect to the
matters set forth in this Bylaw. Nothing in this Bylaw shall be deemed to affect
any rights (A) of stockholders to request inclusion of proposals in the
Corporation's proxy statement pursuant to Rule 14a-8 under the Exchange Act or
(B) of the holders of any series of Preferred Stock to elect Directors under an
applicable Preferred Stock Designation (as defined in the Certificate of
Incorporation).

                  Section 2.8. Procedure for Election of Directors; Required
Vote. Election of Directors at all meetings of the stockholders at which
Directors are to be elected shall be by ballot, and, subject to the rights of
the holders of any series of Preferred Stock to elect Directors under an
applicable Preferred Stock Designation, a plurality of the votes cast thereat
shall elect Directors. Except as otherwise provided by law, the Certificate of
Incorporation, Preferred Stock Designation or these Bylaws, in all matters other
than the election of Directors, the affirmative



                                      -4-
<PAGE>   24

vote of a majority of the voting power of the shares present in person or
represented by proxy at the meeting and entitled to vote on the matter shall be
the act of the stockholders.

                  Section 2.9. Inspectors of Elections; Opening and Closing the
Polls. The Board by resolution shall appoint, or shall authorize an officer of
the Corporation to appoint, one or more inspectors, which inspector or
inspectors may include individuals who serve the Corporation in other
capacities, including, without limitation, as officers, employees, agents or
representatives, to act at the meetings of stockholders and make a written
report thereof. One or more persons may be designated as alternate inspector(s)
to replace any inspector who fails to act. If no inspector or alternate has been
appointed to act or is able to act at a meeting of the stockholders, the
chairman of the meeting shall appoint one or more inspectors to act at the
meeting. Each inspector, before discharging such person's duties, shall take and
sign an oath faithfully to execute the duties of inspector with strict
impartiality and according to the best of such person's ability. The
inspector(s) shall have the duties prescribed by law. The chairman of the
meeting shall fix and announce at the meeting the date and time of the opening
and the closing of the polls for each matter upon which the stockholders will
vote at a meeting.

                  Section 2.10. Conduct of Meetings. The Board may to the extent
not prohibited by law adopt such rules and regulations for the conduct of
meetings of stockholders as it shall deem appropriate. Except to the extent

Corporation shall be managed under the direction of the Board. In addition to
the powers and authorities expressly conferred upon the Board by these Bylaws,

prepaid, or when received in the form of a telegram or facsimile, and shall be

purpose of, any regular or special meeting of the Board need be specified in the
notice of such meeting, except for amendments to these Bylaws, as provided under
Article VIII. A meeting may be held at any time without notice if all the
Directors are present or if those not present waive notice of the meeting in

                  Section 3.6. Action by Consent of Board. To the extent
permitted by applicable law, the Board and any committee thereof may act without

transaction of business, but if at any meeting of the Board there shall be less
than a quorum present, a majority of the Directors present may adjourn the
meeting from time to time without further notice. Subject to the supermajority
voting provisions of Section 3.1, the act of the majority of the Directors
present at a meeting at which a quorum is present shall be the act of the Board.
The Directors present at a duly organized meeting may continue to transact
business until adjournment, notwithstanding the withdrawal of enough Directors
to leave less than a quorum.

                  Section 3.9. Vacancies; Increases in the Number of Directors.

committee of the Board, other than the audit committee, shall include at least

forth by the NYSE as of __ , 2000 for membership on the audit committee of the
Board, with respect to each of Phillips, Duke and the Corporation.

                  (c) Unless the Board shall otherwise provide, a majority of
any committee may fix the time and place of its meetings and, subject to the
supermajority voting provisions of Section 3.1, may determine its action. Notice
of such meetings shall be given to each member of the committee in the manner
provided for in Section 3.5 of these Bylaws. Subject to Section 3.10(a), the
Board shall have power at any time to fill vacancies in, to change the
membership of, or to dissolve any such committee. Nothing herein shall be deemed
to prevent the Board from appointing one or more committees consisting in whole
or in part of persons who are not Directors; provided, however, that no such
committee shall have or may exercise any authority of the Board.

                  Section 3.11. Removal. Any Director or the entire Board may be

by such person's attorney, upon surrender for cancellation of certificates for
at least the same number of shares, with an assignment and power of transfer
endorsed thereon or attached thereto, duly executed, with such proof of the
authenticity of the signature as the Corporation or its agents may reasonably
require. The certificates of stock shall be signed, countersigned and registered
in such manner as the Board may by resolution prescribe, which resolution may
permit all or any of the signatures on such certificates to be in facsimile. In
case any officer, transfer agent or registrar who has signed or whose facsimile
signature has been placed upon a certificate has ceased to be such officer,
transfer agent or registrar before such certificate is issued, it may be issued
by the Corporation with the same effect as if he were such officer, transfer
agent or registrar at the date of issue. Notwithstanding the foregoing
provisions regarding share certificates, the proper officers of the Corporation

such resignation to the Chairman of the Board or the Secretary, and such
resignation shall be deemed to be effective as of the close of business on the
date said notice is received by the Chairman of the Board of the Secretary, or
at such later time as is specified therein. No formal action shall be required
of the Board or the stockholders to make any such resignation effective.

confined to specific instances as the Board may determine. The Chairman of the
Board, the President or any Executive Vice President, Senior Vice President or
Vice President may execute bonds, contracts, deeds, leases and other instruments
to be made or executed for or on behalf of the Corporation. Subject to any
restrictions imposed by the Board, the Chairman of the Board, the President or

Corporation, at meetings of the holders of the stock or other securities of such
other corporation, or to consent in writing, in the name of the Corporation as
such holder, to any action by such other corporation, and may instruct the
person or persons so appointed as to the manner of casting such votes or giving
such consent, and may execute or cause to be executed in the name and on behalf
of the Corporation and under its corporate seal or otherwise, all such written
proxies or other instruments as he may deem necessary or proper in the premises.

Duke Energy Field Services Corporation
370 17th Street, Suite 900
Denver, Colorado 80202

Ladies and Gentlemen:

         We are acting as counsel for Duke Energy Field Services Corporation, a
Delaware corporation (the "Company"), in connection with the proposed offer and
sale (the "Offering") by the Company to the several underwriters (the
"Underwriters") set forth in the underwriting agreement (the "Underwriting
Agreement") to be executed in connection with the Offering by the Company and
Morgan Stanley & Co. Incorporated on behalf of the Underwriters, pursuant to the
prospectus forming a part of a Registration Statement on Form S-1, Registration
No. 333-32502, originally filed with the Securities and Exchange Commission on
March 15, 2000 (such Registration Statement, as amended at the effective date
thereof, being referred to herein as the "Registration Statement"), of an
aggregate of 26,300,000 shares of Common Stock, par value $.01 per share, of the
Company ("Common Stock"), together with a maximum of 3,945,000 shares of Common
Stock which may be sold to the Underwriters pursuant to the over-allotment
option provided in the Underwriting Agreement. Capitalized terms used but not
defined herein have the meanings set forth in the Registration Statement.

         We are rendering this opinion as of the time the Registration Statement
becomes effective in accordance with Section 8(a) of the Securities Act of 1933,
as amended.

         In connection with this opinion, we have assumed that the Registration
Statement, and any amendments thereto (including post-effective amendments),
will have become effective and the shares of Common Stock will be issued and
sold in compliance with applicable federal and state securities laws and in the
manner described in the Registration Statement and the applicable prospectus.

         In connection with the opinion expressed herein, we have examined,
among other things, the Certificate of Incorporation and Bylaws of the Company,
the records of corporate proceedings that have occurred prior to the date hereof
with respect to the Offering, the Registration Statement and the form of
Underwriting Agreement to be executed by the Company and Morgan Stanley & Co.
Incorporated on behalf

of the Underwriters. We have also reviewed such questions of law as we have
deemed necessary or appropriate.

         Based upon the foregoing, we are of the opinion that the shares of
Common Stock proposed to be issued and sold by the Company to the Underwriters
have been validly authorized for issuance and, upon the issuance and delivery
thereof as set forth in the Registration Statement, will be validly issued,
fully paid and nonassessable.

         This opinion is limited in all respects to the Constitution of the
State of Delaware and the Delaware General Corporation Law, as interpreted by
the courts of the State of Delaware.

         We hereby consent to the statements with respect to us under the
heading "Validity of the Common Stock" in the prospectus forming a part of the
Registration Statement and to the filing of this opinion as an exhibit to the
Registration Statement, but we do not thereby admit that we are within the class
of persons whose consent is required under the provisions of the Securities Act
of 1933, as amended, or the rules and regulations of the Securities and Exchange
Commission issued thereunder.

                                             Very truly yours,



                                             VINSON & ELKINS L.L.P.

         2.4 FUNDING OF LOANS.

         Upon receipt of a Notice of Borrowing, the Agent shall promptly inform
the Revolving-A Lenders or the Revolving-B Lenders, as applicable, as to the
terms thereof. Each such Lender shall make its Revolving-A Loan Commitment
Percentage or its Revolving-B Loan Commitment Percentage, as applicable, of the
requested Loans available to the Agent by 1:00 p.m. on the date specified in the
Notice of Borrowing by deposit, in Dollars, of immediately available funds at
the Agency Services Address. The amount of the requested Loans will then be made
available to the Borrowers by the Agent by crediting the account of the
Borrowers on the books of such office of the Agent, to the extent the amount of
such Loans are made available to the Agent.

         No Lender shall be responsible for the failure or delay by any other
Lender in its obligation to make Loans hereunder; provided, however, that the
failure of any Lender to fulfill its obligations hereunder shall not relieve any
other Lender of its obligations hereunder. Unless the Agent shall have been
notified by any Lender prior to the date of any such Loan that such Lender does
not intend to make available to the Agent its portion of the Loans to be made on
such date, the Agent may assume that such Lender has made such amount available
to the Agent on the date of such Loans, and the Agent in reliance upon such
assumption, may (in its sole discretion but without any obligation to do so)
make available to the Borrowers a corresponding amount. If such corresponding
amount is not in fact made available to the Agent, the Agent shall be able to
recover such corresponding amount from such Lender. If such Lender does not pay
such corresponding amount forthwith upon the Agent's demand therefor, the Agent
will promptly notify the Borrowers and the Borrowers shall immediately pay such
corresponding amount within two Business Days to the Agent. The Agent shall also
be entitled to recover from the Lender or the Borrowers, as the case may be,
interest on such corresponding amount in respect of each day from the date such
corresponding amount was made available by the Agent to the Borrowers to the
date such corresponding amount is recovered by the Agent at a per annum rate
equal to (a) from the Borrowers at the applicable rate for such Loan pursuant to
the Notice of Borrowing and (b) from a Lender at the Federal Funds Rate.

         2.5 CONTINUATIONS AND CONVERSIONS.

         The Borrowers shall have the option (subject to the limitations set
forth below), on any Business Day, to continue existing Eurodollar Loans for a
subsequent Interest Period, to convert Base Rate Loans or Floating Eurodollar
Rate Loans into Eurodollar Loans or to convert Eurodollar Loans into Base Rate
Loans or Floating Eurodollar Rate Loans or to convert Base Rate Loans into
Floating Eurodollar Rate Loans or to convert Floating Eurodollar Rate Loans into
Base Rate Loans; provided, however, that (a) each such continuation or
conversion must be requested by the Borrowers pursuant to a written Notice of
Continuation/Conversion, in the form of Exhibit 2.5, in compliance with the
terms set forth below, (b) if a Eurodollar Loan is continued or converted into a
Base Rate Loan or a Floating Eurodollar Rate Loan on any day other than the last
day of the Interest Period applicable thereto, then the Borrowers shall be
subject to the provisions set forth in Section 4.3, (c) Eurodollar Loans may not
be continued nor may Base Rate Loans or Floating Eurodollar Rate Loans be
converted into Eurodollar Loans during the existence and continuation of a
Default or Event of Default and (d) any request to


                                       13
<PAGE>   18

extend a Eurodollar Loan that fails to comply with the terms hereof or any
failure to request an extension of a Eurodollar Loan at the end of an Interest
Period shall constitute a conversion to a Base Rate Loan on the last day of the
applicable Interest Period. Each continuation or conversion must be requested by
the Borrowers no later than 11:00 a.m. (i) on the date for a requested
conversion of a Eurodollar Loan to a Base Rate Loan or a Floating Eurodollar
Rate Loan or (ii) three Business Days prior to the date for a requested
continuation of a Eurodollar Loan or conversion of a Base Rate Loan or Floating
Eurodollar Rate Loan to a Eurodollar Loan, in each case pursuant to a written
Notice of Continuation/Conversion submitted to the Agent which shall set forth
(A) whether the Borrowers wish to continue or convert such Loans and (B) if the
request is to continue a Eurodollar Loan or convert a Base Rate Loan or a
Floating Eurodollar Rate Loan to a Eurodollar Loan, the Interest Period
applicable thereto. Notwithstanding anything herein to the contrary, unless a
Notice of Continuation/Conversion to the contrary has been timely received all
Floating Eurodollar Rate Loans outstanding on the date sixty (60) days after the
Closing Date shall automatically be converted into Base Rate Loans in accordance
with the terms hereof. Subsequent to the date sixty (60) days after the Closing
Date, the Borrowers may no longer convert Base Rate Loans or Eurodollar Loans
into Floating Eurodollar Rate Loans.

         2.6 MINIMUM AMOUNTS.

         Each request for a Loan or a conversion or continuation hereunder shall
be subject to the following requirements: (a) each Eurodollar Loan shall be in a
minimum amount of $10,000,000 (and in integral multiples of $1,000,000 in excess
thereof), (b) each Base Rate Loan and each Floating Rate Eurodollar Loan shall
be in a minimum amount of the lesser of $10,000,000 (and in integral multiples
of $1,000,000 in excess thereof) or the remaining amount available to be
borrowed and (c) no more than ten Eurodollar Loans shall be outstanding
hereunder at any one time. For the purposes of this Section, all Eurodollar
Loans with the same Interest Periods that begin and end on the same date shall
be considered as one Eurodollar Loan, but Eurodollar Loans with different
Interest Periods, even if they begin on the same date, shall be considered
separate Eurodollar Loans.

         each partial reduction shall be in an aggregate amount at least equal
         to $10,000,000 and in integral multiples of $1,000,000 above such
         amount, (b) no reduction shall be made which would reduce the
         Revolving-A Loan Commitment to an amount less than the sum of the then
         outstanding Revolving-A Loans and (c) no reduction shall be made which
         would reduce the Revolving-B Loan Commitment to an amount less than the
         sum of the then outstanding Revolving-B Loans.

                  (b) The Revolving-B Loan Commitment shall be automatically
         reduced at the time and by the amount of any prepayment of the
         Revolving-B Loans required by


                                       14

                  (a) Each of the Borrowers is accepting joint and several
         liability hereunder in consideration of the financial accommodation to
         be provided by the Lenders under this Credit Agreement, for the mutual
         benefit, directly and indirectly, of each of the Borrowers and in
         consideration of the undertakings of each of the Borrowers to accept
         joint and several liability for the obligations of each of them.

                  (b) Each of the Borrowers jointly and severally hereby
         irrevocably and unconditionally accepts, not merely as a surety but
         also as a co-debtor, joint and several liability with the other
         Borrower with respect to the payment and performance of all of the
         obligations arising under this Credit Agreement and the other Credit
         Documents, it being the intention of the parties hereto that all of the
         Borrowers Obligations shall be the joint and several obligations of
         each of the Borrowers without preferences or distinction between them.

                  (c) If and to the extent that either of the Borrowers shall
         fail to make any payment with respect to any of the obligations
         hereunder as and when due or to perform any of such obligations in
         accordance with the terms thereof, then in each such event, the other
         Borrower will make such payment with respect to, or perform, such
         obligation.

                   (d) The provisions of this Section 2.9 are made for the
         benefit of the Lenders and their successors and assigns, and may be
         enforced by them from time to time against either of the Borrowers as
         often as occasion therefor may arise and without requirement on the
         part of the Lenders first to marshall any of its claims or to exercise
         any of its rights against the other Borrower or to exhaust any remedies
         available to it against the other Borrower or to resort to any other
         source or means of obtaining payment of any of the Borrowers
         Obligations hereunder or to elect any other remedy. The provisions of
         this


                                       15
<PAGE>   20

         Section 2.9 shall remain in effect until all the Borrowers Obligations
         hereunder shall have been paid in full or otherwise fully satisfied. If
         at any time, any payment, or any part thereof, made in respect of any
         of the Borrowers Obligations, is rescinded or must otherwise be
         restored or returned by the Lenders upon the insolvency, bankruptcy or
         reorganization of any of the Borrowers, or otherwise, the provisions of
         this Section 2.9 will forthwith be reinstated and in effect as though
         such payment had not been made.

                  (e) Notwithstanding any provision to the contrary contained
         herein or in any of the other Credit Documents, to the extent the
         obligations of either Borrower shall be adjudicated to be invalid or
         unenforceable for any reason (including, without limitation, because of
         any applicable state or federal law relating to fraudulent conveyances
         or transfers) then the obligations of such Borrower hereunder shall be
         limited to the maximum amount that is permissible under applicable law
         (whether federal or state and including, without limitation, the
         Bankruptcy Code).

                  (f) Each Borrower hereby appoints the other Borrower to act as
         its agent for all purposes under this Credit Agreement (including,
         without limitation, with respect to all matters relating to the
         borrowing and repayment of Loans) and agrees that (i) a Borrower may
         execute such documents on behalf of the other Borrower as it deems
         appropriate and the other Borrower shall be obligated by all of the
         terms of any such document executed on its behalf, (ii) any notice or
         communication delivered by the Agent or a Lender to a Borrower shall be
         deemed delivered to both Borrowers and (iii) the Agent and the Lenders
         may accept, and be permitted to rely on, any document, instrument or
         agreement executed by one Borrower on behalf of the other Borrower.

         2.10 LIMITATION OF LIABILITY OF BORROWERS.

         Notwithstanding anything in this Credit Agreement or in the Notes to
the contrary, including without limitation, Section 2.9:

                  (a) Duke Energy Field Services Corporation shall have no
         rights or obligations as a Borrower, and will not be subject to the
         terms of the Credit Documents, until (i) consummation of the merger of
         Phillips Gas Company Shareholder, Inc., a Subsidiary of Phillips
         Petroleum Company, with and into Duke Energy Field Services Corporation
         and (ii) notification from the Borrowers to the Lenders that such
         merger has occurred and that, going forward, Duke Energy Field Services
         Corporation will irrevocably have all of the rights and obligations of
         a Borrower, jointly and severally with Duke Energy Field Services, LLC,
         under the Credit Documents (including, without limitation, any Loans
         made prior to such notification) and will be subject to the terms of
         the Credit Documents.

                  (b) The agreement by Duke Energy Field Services Corporation to
         become jointly and severally liable with Duke Energy Field Services,
         LLC for the indebtedness under the Credit Documents pursuant to
         subsection (a) above shall be accomplished in two phases: (i)
         initially, Duke Energy Field Services Corporation shall become directly
         liable for 69.7% of such indebtedness and shall become indirectly
         liable for 30.3% of such


                                       16
<PAGE>   21

         indebtedness through Phillips Gas Company ("PGC"), a Delaware
         corporation and a wholly-owned Subsidiary of Duke Energy Field Services
         Corporation (PGC being directly liable for such 30.3%), in each case
         jointly and severally with Duke Energy Field Services, LLC, which shall
         remain jointly and severally liable for 100% of such indebtedness; and
         (ii) immediately thereafter, Duke Energy Field Services Corporation
         shall become directly liable for the 30.3% of such indebtedness
         theretofore attributed to PGC and, thereafter, PGC shall no longer be
         liable, directly or indirectly, for any such indebtedness.

                  (c) On or after the date that, pursuant to subsections (a) and
         (b) above, Duke Energy Field Services Corporation has become directly
         liable for 100% of the indebtedness, rights and obligations of a
         Borrower under the Credit Documents, the Borrowers may, upon written
         notice to the Lenders, release Duke Energy Field Services, LLC from its
         joint and several obligations under the Credit Documents. Thereafter,
         Duke Energy Field Services, LLC will have no rights or obligations
         under the Credit Documents, will no longer be subject to the terms of
         the Credit Documents and all obligations owing pursuant to the Credit
         Documents shall be the sole responsibility of Duke Energy Field
         Services Corporation.

                  (d) Notwithstanding the use of the term "Borrowers" as set
         forth in the Credit Documents: (i) prior to Duke Energy Field Services
         Corporation having any rights or obligations as a Borrower, as set
         forth in clause (a) above, the terms "Borrowers" or "a Borrower" as
         used in the Credit Documents shall only mean a reference to Duke Energy
         Field Services, LLC and (ii) on and after the date that Duke Energy
         Field Services, LLC is released from liability, in accordance with
         clause (c) above, the terms "Borrowers" or "a Borrower" as used in the
         Credit Documents shall only mean a reference to Duke Energy Field
         Services Corporation.

                                   SECTION 3.

                                    PAYMENTS

         3.1 INTEREST.

                  (a) Interest Rate.

                           (i) All Base Rate Loans shall accrue interest at the
                  Base Rate.

                           (ii) All Eurodollar Loans shall accrue interest at
                  the Adjusted Eurodollar Rate applicable to such Eurodollar
                  Loan.

                           (iii) all Floating Eurodollar Rate Loans shall accrue
                  interest at the Floating Eurodollar Rate.

                  (b) Default Rate of Interest. Upon the occurrence, and during
         the continuation, of an Event of Default, all past due principal of
         and, to the extent permitted by law, past due


                                       17
<PAGE>   22

         interest on, the Loans and any other past due amounts owing hereunder
         or under the other Credit Documents shall bear interest, payable on
         demand, at a per annum rate equal to one percent (1%) plus the rate
         which would otherwise be applicable (or if no rate is applicable, then
         the rate for Loans that are Base Rate Loans plus one percent (1%) per
         annum).

                  (c) Interest Payments. Interest on Loans shall be due and
         payable in arrears on each Interest Payment Date.

         3.2 PREPAYMENTS.

                  (a) Voluntary Prepayments. The Borrowers shall have the right
         to prepay Loans in whole or in part from time to time without premium
         or penalty; provided, however, that (i) Eurodollar Loans may only be
         prepaid on three Business Days' prior written notice to the Agent and
         any prepayment of Eurodollar Loans will be subject to Section 4.3; and
         (ii) each such partial prepayment of Loans shall be in the minimum
         principal amount of $10,000,000. Any payments made under this Section
         3.2(a) shall be applied as the Borrowers may elect; provided that if
         the Borrowers fail to specify how a voluntary prepayment should be
         applied then such prepayment shall be applied first to Base Rate Loans,
         second to Floating Eurodollar Rate Loans and third to Eurodollar Loans
         in direct order of Interest Period maturities, in each case, pro rata
         between Revolving-A Loans and Revolving-B Loans.

                  (b) Mandatory Prepayments.

                           (i) Revolving-A Committed Amount; Revolving-B
                  Committed Amount. If at any time the amount of Revolving-A
                  Loans outstanding exceeds the Revolving-A Loan Commitment, the
                  Borrowers shall immediately make a principal payment to the
                  Agent in a manner and in an amount such that the outstanding
                  Revolving-A Loans are less than or equal to the Revolving-A
                  Loan Commitment. If at any time the amount of Revolving-B
                  Loans outstanding exceeds the Revolving-B Loan Commitment, the
                  Borrowers shall immediately make a principal payment to the
                  Agent in a manner and in an amount such that the outstanding
                  Revolving-B Loans are less than or equal to the Revolving-B
                  Loan Commitment.

                           (ii) Debt Issuance. Promptly upon receipt by a
                  Borrower of proceeds from any Debt Issuance, such Borrower
                  shall forward 100% of the Net Cash Proceeds of such Debt
                  Issuance to the Lenders as a prepayment of the Revolving-B
                  Loans (to be applied as set forth in Section 3.2(c) below).

                           (iii) Equity Issuance. Promptly upon receipt by a
                  Borrower of proceeds from an Equity Issuance, such Borrower
                  shall forward 100% of the Net Cash Proceeds of such Equity
                  Issuance to the Lenders as a prepayment of the Revolving-B
                  Loans (to be applied as set forth in Section 3.2(c) below).

                  (c) Applications of Prepayments. All amounts required to be
         paid pursuant to Section 3.2(b)(i) shall be applied to Revolving-A
         Loans or Revolving-B Loans, as


                                       18
<PAGE>   23

         applicable. All amounts required to be paid pursuant to Sections
         3.2(b)(ii) and (iii) shall be applied to Revolving-B Loans (with a
         corresponding permanent reduction in the Revolving-B Loan Commitment).
         All amounts payable pursuant to Section 3.2(b) shall be applied, to the
         extent applicable, first to Base Rate Loans, then to Floating
         Eurodollar Rate Loans and then to Eurodollar Loans in the direct order
         of Interest Period maturities.

         3.3 PAYMENT IN FULL AT MATURITY.

         On the Maturity Date, the entire outstanding principal balance of all
Loans, together with accrued but unpaid interest and all other sums owing under
this Credit Agreement, shall be due and payable in full, unless accelerated
sooner pursuant to Section 9.2.

         3.4 FACILITY FEES.

                  (a) In consideration of the Revolving-A Loan Commitment being
         made available by the Revolving-A Lenders, the Borrowers agree to pay
         to the Agent, for the pro rata benefit of each Revolving-A Lender, a
         fee equal to .125% multiplied by the daily average Revolving-A Loan
         Commitment during the applicable period of determination (the
         "Revolving-A Facility Fees").

                  (b) In consideration of the Revolving-B Loan Commitment being
         made available by the Revolving-B Lenders, the Borrowers agree to pay
         to the Agent, for the pro rata benefit of each Revolving-B Lender, a
         fee equal to .125% multiplied by the daily average Revolving-B Loan
         Commitment during the applicable period of determination (the
         "Revolving-B Facility Fees").

                  (c) The accrued Revolving-A Facility Fees and the accrued
         Revolving-B Facility Fees (collectively, the "Facility Fees") shall be
         due and payable in arrears on the first Business Day after the end of
         each fiscal quarter of the Borrowers (as well as on the Maturity Date)
         for the immediately preceding fiscal quarter (or portion thereof),
         beginning with the first of such dates to occur after the Closing Date.

         3.5 PLACE AND MANNER OF PAYMENTS.

         All payments of principal, interest, fees, expenses and other amounts
to be made by a Borrower under this Credit Agreement shall be made without
setoff, deduction or counterclaim and received not later than 2:00 p.m. on the
date when due in Dollars and in immediately available funds by the Agent at the
Agency Services Address. A Borrower shall, at the time it makes any payment
under this Credit Agreement, specify to the Agent the Loans, fees or other
amounts payable by a Borrower hereunder to which such payment is to be applied
(and in the event that it fails to specify, or if such application would be
inconsistent with the terms hereof, the Agent shall distribute such payment to
the Lenders in such manner as it reasonably determines in its sole discretion).
The Agent will distribute such payments to the applicable Lenders on the same
Business Day if any such payment is received prior to 2:00 p.m.; otherwise the
Agent will distribute each payment to the applicable Lenders prior to 12:00 noon
on the next succeeding Business Day. Whenever any


                                       19
<PAGE>   24

payment hereunder shall be stated to be due on a day which is not a Business
Day, the due date thereof shall be extended to the next succeeding Business Day
(subject to accrual of interest and fees for the period of such extension),
except that in the case of Eurodollar Loans, if the extension would cause the
payment to be made in the next following calendar month, then such payment shall
be made on the next preceding Business Day.

         3.6 PRO RATA TREATMENT.

         Except to the extent otherwise provided herein, all Loans, each payment
or prepayment of principal of any Loan, each payment of interest on the Loans,
each payment of Facility Fees, each reduction of the Revolving-A Loan
Commitment, each reduction of the Revolving-B Loan Commitment and each
conversion or continuation of any Loans, shall be allocated pro rata among the
applicable Lenders in accordance with their respective Revolving-A Loan
Commitment Percentages or Revolving-B Loan Commitment Percentages; provided
that, if any Lender shall have failed to pay its applicable pro rata share of
any Loan, then any amount to which such Lender would otherwise be entitled
pursuant to this Section 3.6 shall instead be payable to the Agent until the
share of such Loan not funded by such Lender has been repaid and any interest
owed by such Lender as result of such failure to fund has been paid; and
provided further, that in the event any amount paid to any Lender pursuant to
this Section 3.6 is rescinded or must otherwise be returned by the Agent, each
Lender shall, upon the request of the Agent, repay to the Agent the amount so
paid to such Lender, with interest for the period commencing on the date such
payment is returned by the Agent until the date the Agent receives such
repayment at a rate per annum equal to, during the period to but excluding the
date two Business Days after such request, the Federal Funds Rate, and
thereafter, the Base Rate plus one percent (1%) per annum.

         3.7 COMPUTATIONS OF INTEREST AND FEES.

                  (a) Except for Base Rate Loans that are based upon the Prime
         Rate, on which interest shall be computed on the basis of a 365 or 366
         day year as the case may be, all computations of interest and fees
         hereunder shall be made on the basis of the actual number of days
         elapsed over a year of 360 days.

                  (b) It is the intent of the Lenders and the Borrowers to
         conform to and contract in strict compliance with applicable usury law
         from time to time in effect. All agreements between the Lenders and the
         Borrowers are hereby limited by the provisions of this paragraph which
         shall override and control all such agreements, whether now existing or
         hereafter arising and whether written or oral. In no way, nor in any
         event or contingency (including but not limited to prepayment or
         acceleration of the maturity of any obligation), shall the interest
         taken, reserved, contracted for, charged, or received under this Credit
         Agreement, under the Notes or otherwise, exceed the maximum nonusurious
         amount permissible under applicable law. If, from any possible
         construction of any of the Credit Documents or any other document,
         interest would otherwise be payable in excess of the maximum
         nonusurious amount, any such construction shall be subject to the
         provisions of this paragraph and interest owing pursuant to such
         documents shall be automatically reduced to the maximum nonusurious
         amount permitted under applicable law, without the


                                       20
<PAGE>   25

         necessity of execution of any amendment or new document. If any Lender
         shall ever receive anything of value which is characterized as interest
         on the Loans under applicable law and which would, apart from this
         provision, be in excess of the maximum lawful amount, an amount equal
         to the amount which would have been excessive interest shall, without
         penalty, be applied to the reduction of the principal amount owing on
         the Loans and not to the payment of interest, or refunded to the
         Borrowers or the other payor thereof if and to the extent such amount
         which would have been excessive exceeds such unpaid principal amount of
         the Loans. The right to demand payment of the Loans or any other
         indebtedness evidenced by any of the Credit Documents does not include
         the right to receive any interest which has not otherwise accrued on
         the date of such demand, and the Lenders do not intend to charge or
         receive any unearned interest in the event of such demand. All interest
         paid or agreed to be paid to the Lenders with respect to the Loans
         shall, to the extent permitted by applicable law, be amortized,
         prorated, allocated, and spread throughout the full stated term
         (including any renewal or extension) of the Loans so that the amount of
         interest on account of such indebtedness does not exceed the maximum
         nonusurious amount permitted by applicable law.

         3.8 SHARING OF PAYMENTS.

                  Each Lender agrees that, in the event that any Lender shall
         obtain payment in respect of any Loan or any other obligation owing to
         such Lender under this Credit Agreement through the exercise of a right
         of set-off, banker's lien, counterclaim or otherwise (including, but
         not limited to, pursuant to the Bankruptcy Code) in excess of its pro
         rata share as provided for in this Credit Agreement, such Lender shall
         promptly purchase from the other Lenders a participation in such Loans
         and other obligations, in such amounts and with such other adjustments
         from time to time, as shall be equitable in order that all Lenders
         share such payment in accordance with their respective ratable shares
         as provided for in this Credit Agreement. Each Lender further agrees
         that if a payment to a Lender (which is obtained by such Lender through
         the exercise of a right of set-off, banker's lien, counterclaim or
         otherwise) shall be rescinded or must otherwise be restored, each
         Lender which shall have shared the benefit of such payment shall, by
         repurchase of a participation theretofore sold, return its share of
         that benefit to each Lender whose payment shall have been rescinded or
         otherwise restored. The Borrowers agree that any Lender so purchasing
         such a participation may, to the fullest extent permitted by law,
         exercise all rights of payment, including set-off, banker's lien or
         counterclaim, with respect to such participation as fully as if such
         Lender were a holder of such Loan or other obligation in the amount of
         such participation. Except as otherwise expressly provided in this
         Credit Agreement, if any Lender shall fail to remit to the Agent or any
         other Lender an amount payable by such Lender to the Agent or such
         other Lender pursuant to this Credit Agreement on the date when such
         amount is due, such payments shall accrue interest thereon, for each
         day from the date such amount is due until the day such amount is paid
         to the Agent or such other Lender, at a rate per annum equal to the
         Federal Funds Rate. If under any applicable bankruptcy, insolvency or
         other similar law, any Lender receives a secured claim in lieu of a
         setoff to which this Section 3.8 applies, such Lender shall, to the
         extent practicable, exercise its rights


                                       21
<PAGE>   26

         in respect of such secured claim in a manner consistent with the rights
         of the Lenders under this Section 3.8 to share in the benefits of any
         recovery on such secured claim.

         3.9 EVIDENCE OF DEBT.

                  (a) Each Lender shall maintain an account or accounts
         evidencing each Loan made by such Lender to the Borrowers from time to
         time, including the amounts of principal and interest payable and paid
         to such Lender from time to time under this Credit Agreement. Each
         Lender will make reasonable efforts to maintain the accuracy of its
         account or accounts and to promptly update its account or accounts from
         time to time, as necessary.

                  (b) The Agent shall maintain the Register pursuant to Section
         11.3(c), and a subaccount for each Lender, in which Register and
         subaccounts (taken together) shall be recorded (i) the amount, type and
         Interest Period of each such Loan hereunder, (ii) the amount of any
         principal or interest due and payable or to become due and payable to
         each Lender hereunder and (iii) the amount of any sum received by the
         Agent hereunder from or for the account of the Borrowers and each
         Lender's share thereof. The Agent will make reasonable efforts to
         maintain the accuracy of the subaccounts referred to in the preceding
         sentence and to promptly update such subaccounts from time to time, as
         necessary.

                  (c) The entries made in the Register and subaccounts
         maintained pursuant to subsection (b) of this Section 3.9, and the
         entries made in the accounts maintained pursuant to subsection (a) of
         this Section 3.9, if consistent with the entries of the Agent, shall be
         prima facie evidence of the existence and amounts of the obligations of
         the Borrowers therein recorded; provided, however, that the failure of
         any Lender or the Agent to maintain any such account, such Register or
         such subaccount, as applicable, or any error therein, shall not in any
         manner affect the obligation of the Borrowers to repay the Loans made
         by such Lender in accordance with the terms hereof.


                                   SECTION 4.

                      ADDITIONAL PROVISIONS REGARDING LOANS

         4.1 EURODOLLAR LOAN PROVISIONS.

                  (a) Unavailability. If, on or prior to the first day of any
         Interest Period, (i) the Agent shall have determined in good faith
         (which determination shall be conclusive and binding upon the
         Borrowers) that (A) Dollar deposits are not generally available in the
         London interbank Eurodollar market in the applicable principal amounts
         and Interest Period of a requested Eurodollar Loan or (B) by reason of
         circumstances affecting the relevant market, adequate and reasonable
         means do not exist for ascertaining the Eurodollar Rate for such
         Interest Period or for the Floating Eurodollar Rate, or (ii) the Agent
         shall have received


                                       22
<PAGE>   27

         notice from the Required Lenders that the Eurodollar Rate determined or
         to be determined for such Interest Period or the Floating Eurodollar
         Rate, as the case may be, will not adequately and fairly reflect the
         cost to the Lenders of making or maintaining Eurodollar Loans for such
         Interest Period or Floating Eurodollar Rate Loans, as the case may be,
         (as conclusively certified by such Lenders), the Agent shall give
         notice thereof to the Borrowers and the Lenders as soon as practicable
         thereafter. Upon delivery of such notice, (A) any Eurodollar Loans
         requested to be made on the first day of such Interest Period or any
         requested Floating Rate Eurodollar Loans, as the case may be, shall be
         made as Base Rate Loans, (B) any Loans that were to have been converted
         to or continued as Eurodollar Loans or Floating Eurodollar Rate Loans,
         as the case may be, shall be prepaid by the Borrowers or converted to
         or continued as Base Rate Loans and (C) any outstanding Eurodollar
         Loans shall be converted, on the first day of such Interest Period, to
         Base Rate Loans and any Floating Rate Eurodollar Loans shall be
         converted, on the next succeeding Business Day, to Base Rate Loans.
         Until the Agent has withdrawn such notice, no further Eurodollar Loans
         or Floating Eurodollar Rate Loans, as the case may be, shall be made or
         continued as such, nor shall the Borrowers have the right to convert
         Base Rate Loans to Eurodollar Loans or Floating Eurodollar Rate Loans,
         as the case may be.

                  (b) Change in Legality. Notwithstanding any other provision
         herein, if any change, after the date hereof, in any law, governmental
         rule, regulation, guideline or order (including the introduction of any
         new law or governmental rule, regulation, guideline or order) or in the
         interpretation or administration thereof by any Governmental Authority
         charged with the interpretation or administration thereof shall make it
         unlawful for any Lender to make or maintain any Eurodollar Loan or
         Floating Eurodollar Rate Loan then, by written notice to the Borrowers
         and to the Agent, such Lender may:

                           (i) declare that Eurodollar Loans and Floating
                  Eurodollar Rate Loans, and conversions to or continuations of
                  Eurodollar Loans and Floating Eurodollar Rate Loans, will not
                  thereafter be made by such Lender hereunder, whereupon any
                  request by the Borrowers for, or for conversion into or
                  continuation of, Eurodollar Loans or Floating Eurodollar Rate
                  Loans shall, as to such Lender only, be deemed a request for,
                  or for conversion into or continuation of, Base Rate Loans,
                  unless such declaration shall be subsequently withdrawn; and

                           (ii) require that all outstanding Eurodollar Loans
                  and Floating Eurodollar Rate Loans made by it be converted to
                  Base Rate Loans in which event all such Eurodollar Loans and
                  Floating Eurodollar Rate Loans shall be converted to Base Rate
                  Loans either (A) on the last day of the then current Interest
                  Period applicable to such Eurodollar Loan if such Lender can
                  lawfully continue to maintain and fund such Eurodollar Loan or
                  (B) immediately if such Lender shall determine that it may not
                  lawfully continue to maintain and fund such Eurodollar Loan to
                  such day.

                  (c) Requirements of Law. If at any time a Lender shall incur
         increased costs or reductions in the amounts received or receivable
         hereunder with respect to the making, the commitment to make or the
         maintaining of any Eurodollar Loan or Floating Rate Eurodollar


                                       23
<PAGE>   28
         Loan because of (i) any change after the date hereof in any law,
         governmental rule, regulation, guideline or order (including the
         introduction of any new law or governmental rule, regulation, guideline
         or order) or in the interpretation or administration thereof by any
         Governmental Authority charged with the interpretation or
         administration thereof, including, without limitation, the imposition,
         modification or deemed applicability of any reserves, deposits or
         similar requirements (such as, for example, but not limited to, a
         change in official reserve requirements) or (ii) other circumstances
         affecting the London interbank Eurodollar market; then the Borrowers
         shall pay to such Lender promptly upon written demand therefor, such
         additional amounts (in the form of an increased rate of, or a different
         method of calculating, interest or otherwise as such Lender may
         determine in its sole discretion) as may be required to compensate such
         Lender for such increased costs or reductions in amounts receivable
         hereunder. If any Lender becomes entitled to claim any additional
         amounts pursuant to this Section 4.1(c), it shall provide prompt notice
         thereof to the Borrowers, through the Agent, certifying (A) that one of
         the events described in this Section 4.1(c) has occurred and describing
         in reasonable detail the nature of such event, (B) as to the increased
         cost or reduced amount resulting from such event and (C) as to the
         additional amount demanded by such Lender and a reasonably detailed
         explanation of the calculation thereof provided that no such amount
         shall be payable with respect to any period commencing more than 90
         days prior to the date such Lender first notifies the Borrowers of its
         intention to demand compensation therefor under this Section.

                  (d) Regulation D Compensation. In the event that a Lender is
         required to maintain reserves of the type contemplated by the
         definition of "Eurodollar Reserve Percentage", such Lender may require
         the Borrowers to pay, contemporaneously with each payment of interest
         on the Eurodollar Loans, additional interest on the related Eurodollar
         Loan of such Lender at a rate per annum determined by such Lender up to
         but not exceeding the excess of (i)(A) the applicable London Interbank
         Offered Rate divided by (B) one minus the Eurodollar Reserve Percentage
         over (ii) the applicable London Interbank Offered Rate. Any Lender
         wishing to require payment of such additional interest (x) shall so
         notify the Borrowers and the Agent, in which case such additional
         interest on the Eurodollar Loans of such Lender shall be payable to
         such Lender at the place indicated in such notice with respect to each
         Interest Period commencing at least three Business Days after the
         giving of such notice and (y) shall notify the Borrowers at least three
         Business Days prior to each date on which interest is payable on the
         Eurodollar Loans of the amount then due it under this Section. Each
         such notification shall be accompanied by such information as the
         Borrowers may reasonably request.

         Each determination and calculation made by a Lender under this Section
4.1 shall, absent manifest error, be binding and conclusive on the parties
hereto. Any conversions of Eurodollar Loans, or Floating Eurodollar Rate Loans,
as the case may be, made pursuant to this Section 4.1 shall subject the
Borrowers to the payments required by Section 4.3 to the extent applicable. This
Section shall survive termination of this Credit Agreement and the other Credit
Documents and payment of the Loans and all other amounts payable hereunder.

         4.2 CAPITAL ADEQUACY.

         If any Lender has determined that the adoption or becoming effective,
after the date hereof, of any applicable law, rule or regulation regarding
capital adequacy, or any change therein (after the date hereof), or any change
in the interpretation or administration thereof by any Governmental Authority,
central bank or comparable agency charged with the interpretation or
administration thereof, or compliance by such Lender (or its parent corporation)
with any request or directive regarding capital adequacy (whether or not having
the force of law) of any such Governmental Authority, central bank or comparable
agency, has or would have the effect of reducing the rate of return on such
Lender's (or parent corporation's) capital or assets as a consequence of its
commitments or obligations hereunder to a level below that which such Lender (or
its parent corporation) could have achieved but for such adoption,
effectiveness, change or compliance (taking into consideration such Lender's (or
parent corporation's) policies with respect to capital adequacy), then, upon
notice from such Lender (which shall include the basis and calculations in
reasonable detail supporting the compensation requested in such notice), and
receipt by the Borrowers of such written notice from such Lender (with a copy to
the Agent) the Borrowers shall be obligated to pay to such Lender such
additional amount or amounts as will compensate such Lender on an after tax
basis (after taking into account applicable deductions and credits in respect of
the amount so indemnified) for such reduction provided that no such amount shall
be payable with respect to any period commencing more than 90 days prior to the
date such Lender first notifies the Borrowers of its intention to demand
compensation therefor under this Section. Each determination by any Lender of
amounts owing under this Section 4.2 shall, absent manifest error, be conclusive
and binding on the parties hereto. The covenants of this Section 4.2 shall
survive termination of this Credit Agreement and the other Credit Documents and
the payment of the Loans and all other amounts payable hereunder.

         4.3 COMPENSATION.

         The Borrowers promise to indemnify each Lender and to hold each Lender
harmless from any loss or expense which such Lender may sustain or incur as a
consequence of (a) default by the Borrowers in making a borrowing of, conversion
into or continuation of Eurodollar Loans after the Borrowers have given a notice
requesting the same in accordance with the provisions of this Credit Agreement,
(b) default by the Borrowers in making any prepayment of a Eurodollar Loan after
the Borrowers have given a notice thereof in accordance with the provisions of
this Credit Agreement, (c) the making of a prepayment of Eurodollar Loans on a
day which is not the last day of an Interest Period with respect thereto and (d)
the payment, continuation or conversion of a Eurodollar Loan on a day which is
not the last day of the Interest Period applicable thereto or the failure to
repay a Eurodollar Loan when required by the terms of this Credit Agreement.
Such indemnification may include an amount equal to (i) an amount of interest
calculated at the Eurodollar Rate which would have accrued on the amount in
question, for the period from the date of such prepayment or of such failure to
borrow, convert, continue or repay to the last day of the applicable Interest
Period (or, in the case of a failure to borrow, convert or continue, the
Interest Period that would have commenced on the date of such failure) in each
case at the applicable rate of interest for such Eurodollar Loans provided for
herein minus (ii) the amount of interest (as reasonably determined by such
Lender) which would have


                                       25
<PAGE>   30

accrued to such Lender on such amount by placing such amount on deposit for a
comparable period with leading banks in the interbank Eurocurrency market. If
any Lender becomes entitled to claim any additional amounts pursuant to this
Section 4.3, it shall provide prompt notice thereof to the Borrower, through the
Agent, as to the additional amount demanded by such Lender and a reasonably
detailed explanation of the calculation thereof. The covenants in this Section
4.3 shall survive the termination of this Credit Agreement and the payment of
the Loans and all other amounts payable hereunder.

         4.4 TAXES.

                  (a) Except as provided below in this Section 4.4, all payments
         made by the Borrowers under this Credit Agreement and any Notes shall
         be made free and clear of, and without deduction or withholding for or
         on account of, any present or future income, stamp or other taxes,
         levies, imposts, duties, charges, fees, deductions or withholdings, now
         or hereafter imposed, levied, collected, withheld or assessed by any
         court, or governmental body, agency or other official, excluding taxes
         measured by or imposed upon the net income of any Lender or its
         applicable lending office, or any branch or affiliate thereof, and all
         franchise taxes, branch taxes, taxes on doing business or taxes on the
         capital or net worth of any Lender or its applicable lending office, or
         any branch or affiliate thereof, in each case imposed in lieu of net
         income taxes: (i) by the jurisdiction under the laws of which such
         Lender, applicable lending office, branch or affiliate is organized or
         is located, or in which its principal executive office is located, or
         any nation within which such jurisdiction is located or any political
         subdivision thereof; or (ii) by reason of any connection between the
         jurisdiction imposing such tax and such Lender, applicable lending
         office, branch or affiliate other than a connection arising solely from
         such Lender having executed, delivered or performed its obligations, or
         received payment under or enforced, this Credit Agreement or any Notes.
         If any such non-excluded taxes, levies, imposts, duties, charges, fees,
         deductions or withholdings ("Non-Excluded Taxes") are required to be
         withheld from any amounts payable to an Agent or any Lender hereunder
         or under any Notes, (A) the amounts so payable to the Agent or such
         Lender shall be increased to the extent necessary to yield to the Agent
         or such Lender (after payment of all Non-Excluded Taxes) interest or
         any such other amounts payable hereunder at the rates or in the amounts
         specified in this Credit Agreement and any Notes, provided, however,
         that the Borrowers shall be entitled to deduct and withhold any Non-
         Excluded Taxes and shall not be required to increase any such amounts
         payable to any Lender that is not organized under the laws of the
         United States of America or a state thereof if such Lender fails to
         comply with the requirements of paragraph (b) of this Section 4.4
         whenever any Non-Excluded Taxes are payable by the Borrowers, and (B)
         as promptly as possible after requested, the Borrowers shall send to
         the Agent for its own account or for the account of such Lender, as the
         case may be, a certified copy of an original official receipt received
         by the Borrowers showing payment thereof. If the Borrowers fail to pay
         any Non-Excluded Taxes when due to the appropriate taxing authority or
         fails to remit to the Agent the required receipts or other required
         documentary evidence, the Borrowers shall indemnify the Agent and any
         Lender for any incremental Non-Excluded Taxes, interest or penalties
         that may become payable by the


                                       26
<PAGE>   31

         Agent or any Lender as a result of any such failure. The agreements in
         this Section 4.4 shall survive the termination of this Credit Agreement
         and the payment of the Loans and all other amounts payable hereunder.

                  (b) Each Lender that is not incorporated under the laws of the
         United States of America or a state thereof shall:

                                    (i) (A) on or before the date of any payment
                                    by the Borrowers under this Credit Agreement
                                    or the Notes to such Lender, deliver to the
                                    Borrowers and the Agent (x) two duly

                                    Revenue Service Form 1001 or 4224, or

                                    be, certifying that it is entitled to
                                    receive payments under this Credit Agreement
                                    and any Notes without deduction or
                                    withholding of any United States federal
                                    income taxes and (y) an Internal Revenue
                                    Service Form W-8 or W-9, or successor
                                    applicable form, as the case may be,
                                    certifying that it is entitled to an
                                    exemption from United States backup
                                    withholding tax;

                                            (B) deliver to the Borrowers and the
                                    Agent two further copies of any such form or
                                    certification on or before the date that any
                                    such form or certification expires or
                                    becomes obsolete and after the occurrence of
                                    any event requiring a change in the most
                                    recent form previously delivered by it to
                                    the Borrower; and

                                             (C) obtain such extensions of time
                                    for filing and complete such forms or
                                    certifications as may reasonably be
                                    requested by the Borrowers or the Agent; or

                           (ii) in the case of any such Lender that is not a
                  "bank" within the meaning of Section 881(c)(3)(A) of the
                  Internal Revenue Code, (A) represent to the Borrowers (for the
                  benefit of the Borrowers and the Agent) that it is not a bank
                  within the meaning of Section 881 (c)(3)(A) of the Internal
                  Revenue Code, (B) agree to furnish to the Borrowers, on or

                  of Internal Revenue Service Form W-8, or successor applicable
                  form, certifying to such Lender's legal entitlement at the
                  date of such certificate to an exemption from U.S. withholding
                  tax under the provisions of Section 881(c) of the Internal

                  the Borrowers, to provide to the Borrowers (for the benefit of
                  the Borrowers and the Agent) such other forms as may be
                  reasonably required in order to establish the legal
                  entitlement of such Lender to an exemption from withholding
                  with respect to payments under this Credit Agreement and any
                  Notes.

                           Notwithstanding the above, if any change in treaty,
                  law or regulation has occurred after the date such Person
                  becomes a Lender hereunder which renders all such forms
                  inapplicable or which would prevent such Lender from duly
                  completing and delivering any such form with respect to it and
                  such Lender so advises the Borrowers and the Agent, then such
                  Lender shall be exempt from such requirements. Each Person
                  that shall become a Lender or a participant of a Lender
                  pursuant to Section 11.3 shall, upon the effectiveness of the
                  related transfer, be required to provide all of the forms,
                  certifications and statements required pursuant to this
                  subsection (b); provided that in the case of a participant of
                  a Lender, the obligations of such participant of a Lender
                  pursuant to this subsection (b) shall be determined as if the
                  participant of a Lender were a Lender except that such
                  participant of a Lender shall furnish all such required forms,
                  certifications and statements to the Lender from which the
                  related participation shall have been purchased.

         4.5 REPLACEMENT OF LENDERS.

         The Agent and each Lender shall use reasonable efforts to avoid or
mitigate any increased cost or suspension of the availability of an interest
rate under Sections 4.1 through 4.4 above to the greatest extent practicable
(including transferring the Loans to another lending office or Affiliate of a
Lender) unless, in the opinion of the Agent or such Lender, such efforts would
be likely to have an adverse effect upon it. In the event a Lender makes a
request to the Borrowers for additional payments in accordance with Section 4.1,
4.2 or 4.4, or suspends Eurodollar Loans under Section 4.1, then, provided that
no Default or Event of Default has occurred and is continuing at such time, the
Borrowers may, at their own expense (such expense to include any transfer fee
payable to the Agent under Section 11.3(b) and any expense pursuant to Section
4) and in its sole discretion, require such Lender to transfer and assign in
whole (but not in part), without recourse (in accordance with and subject to the
terms and conditions of Section 11.3(b)), all of its interests, rights and
obligations under this Credit Agreement to an Eligible Assignee which shall
assume such assigned obligations (which assignee may be another Lender, if a
Lender accepts such assignment); provided that (a) such assignment shall not
conflict with any law, rule or regulation or order of any court or other
Governmental Authority and (b) the Borrowers or such assignee shall have paid to
the assigning Lender in immediately available funds the principal of and
interest accrued to the date of such payment on the portion of the Loans
hereunder held by such assigning Lender and all other amounts owed to such
assigning Lender hereunder, including amounts owed pursuant to Sections 4.1
through 4.4.

         Each Borrower will, and will cause each Material Subsidiary to, do all
things necessary to preserve and keep in full force and effect its existence and
rights, franchises and authority; provided, however, that, subject to Section
8.3, a Borrower shall not be required to preserve any such existence, right or
franchise if it in good faith determines that preservation thereof is no longer
necessary or desirable in the conduct of its business and that the loss thereof
is not disadvantageous in any material respect to the Lenders.

         Each Borrower will keep, and will cause its Material Subsidiaries to
keep, complete and accurate books and records of its transactions in accordance

contested in good faith by appropriate proceedings.

levies imposed upon it, or upon its income or profits, or upon any of its
properties, before they shall become delinquent, (b) all lawful claims
(including claims for labor, materials and supplies) which, if unpaid, might
give rise to a Lien upon any of its properties, and (c) all of its other
Indebtedness as it shall become due; provided, however, that no Borrower shall
be required to pay any such tax, assessment, charge, levy, claim or Indebtedness
which (i) is being contested in good faith by appropriate proceedings and as to
which adequate reserves therefor have been established in accordance with GAAP
or (ii) the nonpayment of which would not have a Material Adverse Effect.

         7.6 MAINTENANCE OF PROPERTY; INSURANCE.

                  (a) Each Borrower will keep, and will cause each Material
         Subsidiary to keep, all property useful and necessary in its business

         responsible insurance companies, insurance on all their


                                       37
<PAGE>   42

         respective properties in at least such amounts and against at least
         such risks (and with such risk retention) as are usually insured
         against in the same general area by companies of established repute
         engaged in the same or a similar business; provided that self-insurance
         by a Borrower or any such Material Subsidiary shall not be deemed a
         violation of this covenant to the extent that companies engaged in
         similar businesses and owning similar properties in the same general
         areas in which the Borrowers or such Material Subsidiary operates
         self-insure.

         7.7 USE OF PROCEEDS.

agents, attorneys, and appraisers to visit and inspect each Borrower's and its
Material Subsidiaries' property, including its books and records, its accounts
receivable and inventory, each Borrower's and its Material Subsidiaries'

accuracy of information provided to the Lenders and to discuss all such matters
with the officers, employees and representatives of each Borrower and its
Material Subsidiaries.

         7.9 MAINTENANCE OF OWNERSHIP.

         Each Borrower will maintain ownership of all Capital Stock of each
Material Subsidiary, directly or indirectly, free and clear of all Liens except
as permitted by Section 8.3. The Borrowers will take such action as necessary to
ensure that, on and after the date that a Subsidiary of Phillips Petroleum is
merged into Duke Energy Field Services Corporation, Duke Energy Field Services,
LLC will be (and will remain) a wholly owned Subsidiary, direct or indirect, of
Duke Energy Field Services Corporation unless Duke Energy Field Services, LLC is
merged with and into Duke Energy Field Services Corporation.

         relating to such Indebtedness or contained in any instrument or
         agreement evidencing, securing or relating thereto, or any other event
         or condition shall occur or condition exist, the effect of which
         default or other event or condition is to cause any such Indebtedness
         to become due prior to its stated maturity.

                  (g) Judgments. One or more judgments, orders, or decrees shall
         be entered against a Borrower or a Material Subsidiary involving a
         liability of $50,000,000 or more, in the aggregate, (to the extent not
         paid or covered by insurance provided by a carrier who has acknowledged
         coverage) and such judgments, orders or decrees shall continue
         unsatisfied, undischarged and unstayed for a period ending on the first
         to occur of (i) the last day on which such judgment, order or decree
         becomes final and unappealable and, where applicable, with the status
         of a judicial lien or (ii) 45 days.

                  (h) ERISA. The occurrence of any of the following events or
         conditions which could result in a liability of a Borrower or an ERISA
         Affiliate of $50,000,000 or more in the aggregate: (i) any "accumulated
         funding deficiency," as such term is defined in Section 302 of ERISA
         and Section 412 of the Code, whether or not waived, shall exist with
         respect to any Plan, or any lien shall arise on the assets of a
         Borrower or any ERISA Affiliate in favor of the PBGC or a Plan; (ii) a
         Termination Event shall occur with respect to a Single Employer Plan
         which is, in the reasonable opinion of the Agent, likely to result in
         the termination of such Plan for purposes of Title IV of ERISA; (iii) a
         Termination Event shall occur with respect to a Multiemployer Plan or
         Multiple Employer Plan which is, in the reasonable opinion of the
         Agent, likely to result in (A) the termination of such Plan for
         purposes of Title IV of ERISA, or (B) a Borrower or any ERISA Affiliate
         incurring any liability in connection with a withdrawal from,
         reorganization of (within the meaning of Section 4241 of ERISA), or
         insolvency (within the meaning of Section 4245 of ERISA) of such Plan;
         or (iv) any prohibited transaction (within the meaning of Section 406
         of ERISA or Section 4975 of the Code) or breach of fiduciary
         responsibility shall occur which would


                                       43
<PAGE>   48

         be reasonably expected to subject a Borrower or any ERISA Affiliate to
         any liability under Sections 406, 409, 502(i), or 502(l) of ERISA or
         Section 4975 of the Code, or under any agreement or other instrument
         pursuant to which a Borrower or any ERISA Affiliate has agreed or is
         required to indemnify any person against any such liability.

                  (i) Change of Control. The occurrence of any Change of
         Control.

         9.2 ACCELERATION; REMEDIES.

         Upon the occurrence of an Event of Default, and at any time thereafter
unless and until such Event of Default has been waived by the Required Lenders
(or the Lenders as may be required hereunder), the Agent may, with the consent
of the Super Required Lenders, and shall, upon the request and direction of the
Super Required Lenders, by written notice to the Borrowers take any of the
following actions without prejudice to the rights of the Agent or any Lender to
enforce its claims against the Borrowers, except as otherwise specifically
provided for herein:

                  (i) Termination of Commitments. Declare the Commitments
         terminated whereupon the Commitments shall be immediately terminated.

                  (ii) Acceleration of Loans. Declare the unpaid amount of all
         Borrowers Obligations to be due whereupon the same shall be immediately
         due and payable without presentment, demand, protest or other notice of
         any kind, all of which are hereby waived by the Borrower.

                  (iii) Enforcement of Rights. Enforce any and all rights and
         interests created and existing under the Credit Documents, including,
         without limitation, all rights of set-off.

Notwithstanding the foregoing, if an Event of Default specified in Section
9.1(e) shall occur, then the Commitments shall automatically terminate and all
Loans, all accrued interest in respect thereof, all accrued and unpaid fees and
other indebtedness or obligations owing to the Lenders and the Agent hereunder
shall immediately become due and payable without the giving of any notice or
other action by the Agent or the Lenders.

Notwithstanding the fact that enforcement powers reside primarily with the
Agent, each Lender has, to the extent permitted by law, a separate right of
payment and shall be considered a separate "creditor" holding a separate "claim"
within the meaning of Section 101(5) of the Bankruptcy Code or any other
insolvency statute.


                                       44

         9.3 ALLOCATION OF PAYMENTS AFTER EVENT OF DEFAULT.

         Notwithstanding any other provision of this Credit Agreement, after the
occurrence of an Event of Default, all amounts collected or received by the
Agent or any Lender on account of amounts outstanding under any of the Credit
Documents shall be paid over or delivered as follows:

                  FIRST, to the payment of all reasonable out-of-pocket costs
         and expenses (including without limitation reasonable attorneys' fees)
         of the Agent and the Lenders in connection with enforcing the rights of
         the Lenders under the Credit Documents, pro rata as set forth below;

                  SECOND, to payment of any fees owed to the Agent, or any
         Lender, pro rata as set forth below;

                  THIRD, to the payment of all accrued interest payable to the
         Lenders hereunder, pro rata as set forth below;

                  FOURTH, to the payment of the outstanding principal amount of
         the Loans, pro rata as set forth below;

                  FIFTH, to all other obligations which shall have become due
         and payable under the Credit Documents and not repaid pursuant to
         clauses "FIRST" through "FOURTH" above; and

                  SIXTH, to the payment of the surplus, if any, to whomever may
         be lawfully entitled to receive such surplus.

In carrying out the foregoing, (a) amounts received shall be applied in the
numerical order provided until exhausted prior to application to the next
succeeding category and (b) each of the Lenders shall receive an amount equal to
its pro rata share (based on the proportion that the then outstanding Loans held
by such Lender bears to the aggregate then outstanding Loans), of amounts
available to be applied.


                                   SECTION 10

                                AGENCY PROVISIONS

         10.1 APPOINTMENT.

         Each Lender hereby designates and appoints Bank of America, N.A. as
agent of such Lender to act as specified herein and the other Credit Documents,
and each such Lender hereby authorizes the Agent, as the agent for such Lender,
to take such action on its behalf under the provisions of this Credit Agreement
and the other Credit Documents and to exercise such powers


                                       45
<PAGE>   50

and perform such duties as are expressly delegated by the terms hereof and of
the other Credit Documents, together with such other powers as are reasonably
incidental thereto. Notwithstanding any provision to the contrary elsewhere
herein and in the other Credit Documents, the Agent shall not have any duties or
responsibilities, except those expressly set forth herein and therein, or any
fiduciary relationship with any Lender, and no implied covenants, functions,
responsibilities, duties, obligations or liabilities shall be read into this
Credit Agreement or any of the other Credit Documents, or shall otherwise exist
against the Agent. The provisions of this Section are solely for the benefit of
the Agent and the Lenders and the Borrowers shall not have any rights as a third
party beneficiary of the provisions hereof. In performing its functions and
duties under this Credit Agreement and the other Credit Documents, the Agent
shall act solely as agent of the Lenders and does not assume and shall not be
deemed to have assumed any obligation or relationship of agency or trust with or
for a Borrower.

         10.2 DELEGATION OF DUTIES.

         The Agent may execute any of its duties hereunder or under the other
Credit Documents by or through agents or attorneys-in-fact and shall be entitled
to advice of counsel concerning all matters pertaining to such duties. The Agent
shall not be responsible to the Lenders for the negligence or misconduct of any
agents or attorneys-in-fact selected by it with reasonable care.

         10.3 EXCULPATORY PROVISIONS.

         Neither the Agent nor any of its officers, directors, employees,
agents, attorneys-in-fact or Affiliates shall be liable for any action lawfully
taken or omitted to be taken by it or such Person under or in connection
herewith or in connection with any of the other Credit Documents (except for its
or such Person's own gross negligence or willful misconduct), or responsible in
any manner to any of the Lenders for any recitals, statements, representations
or warranties made by a Borrower contained herein or in any of the other Credit
Documents or in any certificate, report, statement or other document referred to
or provided for in, or received by the Agent under or in connection herewith or
in connection with the other Credit Documents, or enforceability or sufficiency
therefor of any of the other Credit Documents, or for any failure of a Borrower
to perform its obligations hereunder or thereunder. The Agent shall not be
responsible to any Lender for the effectiveness, genuineness, validity,
enforceability, collectibility or sufficiency of this Credit Agreement, or any
of the other Credit Documents or for any representations, warranties, recitals
or statements made herein or therein or made by a Borrower in any written or
oral statement or in any financial or other statements, instruments, reports,
certificates or any other documents in connection herewith or therewith
furnished or made by the Agent to the Lenders or by or on behalf of a Borrower
to the Agent or any Lender or be required to ascertain or inquire as to the
performance or observance of any of the terms, conditions, provisions, covenants
or agreements contained herein or therein or as to the use of the proceeds of
the Loans or of the existence or possible existence of any Default or Event of
Default or to inspect the properties, books or records of a Borrower. The Agent
is not a trustee for the Lenders and owes no fiduciary duty to the Lenders.


                                       46
<PAGE>   51


         10.4 RELIANCE ON COMMUNICATIONS.

         The Agent shall be entitled to rely, and shall be fully protected in
relying, upon any note, writing, resolution, notice, consent, certificate,
affidavit, letter, cablegram, telegram, telecopy, telex or teletype message,
statement, order or other document or conversation believed by it to be genuine
and correct and to have been signed, sent or made by the proper Person or
Persons and upon advice and statements of legal counsel (including, without
limitation, counsel to the Borrowers, independent accountants and other experts
selected by the Agent with reasonable care). The Agent may deem and treat the
Lenders as the owner of its interests hereunder for all purposes unless a
written notice of assignment, negotiation or transfer thereof shall have been
filed with the Agent in accordance with Section 11.3(b). The Agent shall be
fully justified in failing or refusing to take any action under this Credit
Agreement or under any of the other Credit Documents unless it shall first
receive such advice or concurrence of the Required Lenders as it deems
appropriate or it shall first be indemnified to its satisfaction by the Lenders
against any and all liability and expense which may be incurred by it by reason
of taking or continuing to take any such action. The Agent shall in all cases be
fully protected in acting, or in refraining from acting, hereunder or under any
of the other Credit Documents in accordance with a request of the Required
Lenders (or to the extent specifically provided in Section 11.6, all the
Lenders) and such request and any action taken or failure to act pursuant
thereto shall be binding upon all the Lenders (including their successors and
assigns).

         10.5 NOTICE OF DEFAULT.

         The Agent shall not be deemed to have knowledge or notice of the
occurrence of any Default or Event of Default hereunder unless the Agent has
received notice from a Lender or the Borrowers referring to the Credit Document,
describing such Default or Event of Default and stating that such notice is a
"notice of default." In the event that the Agent receives such a notice, the
Agent shall give prompt notice thereof to the Lenders. The Agent shall take such
action with respect to such Default or Event of Default as shall be reasonably
directed by the Required Lenders.

         10.6 NON-RELIANCE ON AGENT AND OTHER LENDERS.

         Each Lender expressly acknowledges that neither the Agent nor any of
its officers, directors, employees, agents, attorneys-in-fact or Affiliates has
made any representations or warranties to it and that no act by the Agent or any
Affiliate thereof hereinafter taken, including any review of the affairs of the
Borrowers, shall be deemed to constitute any representation or warranty by the
Agent to any Lender. Each Lender represents to the Agent that it has,
independently and without reliance upon the Agent or any other Lender, and based
on such documents and information as it has deemed appropriate, made its own
appraisal of and investigation into the business, assets, operations, property,
financial and other conditions, prospects and creditworthiness of the Borrowers
and made its own decision to make its Extensions of Credit hereunder and enter
into this Credit Agreement. Each Lender also represents that it will,
independently and without reliance upon the Agent or any other Lender, and based
on such documents and information as it shall deem appropriate at the time,
continue to make its own credit analysis, appraisals and decisions in taking or
not taking action under this Credit Agreement, and to make such investigation as
it deems


                                       47
<PAGE>   52

necessary to inform itself as to the business, assets, operations, property,
financial and other conditions, prospects and creditworthiness of the Borrowers.
Except for notices, reports and other documents expressly required to be
furnished to the Lenders by the Agent hereunder, the Agent shall not have any
duty or responsibility to provide any Lender with any credit or other
information concerning the business, operations, assets, property, financial or
other conditions, prospects or creditworthiness of the Borrowers which may come
into the possession of the Agent or any of its officers, directors, employees,
agents, attorneys-in-fact or Affiliates.

         10.7 INDEMNIFICATION.

         Each Lender agrees to indemnify the Agent in its capacity as such (to
the extent not reimbursed by the Borrowers and without limiting the obligation
of the Borrowers to do so), ratably according to its Commitment Percentage, from
and against any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements of any kind
whatsoever which may at any time (including without limitation at any time
following the payment in full of the Borrowers Obligations) be imposed on,
incurred by or asserted against the Agent in its capacity as such in any way
relating to or arising out of this Credit Agreement or the other Credit
Documents or any documents contemplated by or referred to herein or therein or
the transactions contemplated hereby or thereby or any action taken or omitted
by the Agent under or in connection with any of the foregoing; provided that no
Lender shall be liable for the payment of any portion of such liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements resulting from the gross negligence or willful
misconduct of the Agent. If any indemnity furnished to the Agent for any purpose
shall, in the opinion of the Agent, be insufficient or become impaired, the
Agent may call for additional indemnity and cease, or not commence, to do the
acts indemnified against until such additional indemnity is furnished. The
agreements in this Section 10.7 shall survive the payment of the Borrowers
Obligations and all other amounts payable hereunder and under the other Credit
Documents and the termination of the Commitments.

         10.8 AGENT IN ITS INDIVIDUAL CAPACITY.

         The Agent and its Affiliates may make loans to, accept deposits from
and generally engage in any kind of business with the Borrowers as though the
Agent were not Agent hereunder. With respect to the Loans made and all Borrowers
Obligations owing to it, the Agent shall have the same rights and powers under
this Credit Agreement as any Lender and may exercise the same as though it were
not the Agent, and the terms "Lender" and "Lenders" shall include the Agent in
its individual capacity.

         10.9 SUCCESSOR AGENT.

         The Agent may, at any time, resign upon 30 days written notice to the
Lenders and the Borrowers. Upon any such resignation, the Borrowers with the
consent of the Required Lenders (such consent of the Required Lenders not to be
unreasonably withheld or delayed) shall have the right to appoint a successor
Agent. If no successor Agent shall have been so appointed and shall have
accepted such appointment within 30 days after the notice of resignation, then
the retiring Agent shall select a successor Agent provided such successor is a
Lender hereunder or qualifies as


                                       48
<PAGE>   53

an Eligible Assignee (or if no Eligible Assignee shall have been so appointed by
the retiring Agent and shall have accepted such appointment, then the Lenders
shall perform all obligations of the retiring Agent hereunder until such time,
if any, as a successor Agent shall have been appointed and shall have accepted
such appointment as provided for above). Upon the acceptance of any appointment
as Agent hereunder by a successor, such successor Agent shall thereupon succeed
to and become vested with all the rights, powers, privileges and duties of the
retiring Agent, and the retiring Agent shall be discharged from its duties and
obligations as Agent, as appropriate, under this Credit Agreement and the other
Credit Documents and the provisions of this Section 10.9 shall inure to its
benefit as to any actions taken or omitted to be taken by it while it was Agent
under this Credit Agreement.


                                   SECTION 11.

                                  MISCELLANEOUS

         11.1 NOTICES.

         Except as otherwise expressly provided herein, all notices and other
communications shall have been duly given and shall be effective (a) when
delivered, (b) when transmitted via telecopy (or other facsimile device), (c)
the Business Day following the day on which the same has been delivered prepaid
(or pursuant to an invoice arrangement) to a reputable national overnight air
courier service, or (d) the third Business Day following the day on which the
same is sent by certified or registered mail, postage prepaid, in each case to
the respective parties at the address or telecopy numbers set forth on Schedule
11.1, or at such other address as such party may specify by written notice to
the other parties hereto.

         11.2 RIGHT OF SET-OFF.

         In addition to any rights now or hereafter granted under applicable law
or otherwise, and not by way of limitation of any such rights, upon the
occurrence of an Event of Default and the commencement of remedies described in
Section 9.2, each Lender is authorized at any time and from time to time,
without presentment, demand, protest or other notice of any kind (all of which
rights being hereby expressly waived), to set-off and to appropriate and apply
any and all deposits (general or special) and any other indebtedness at any time
held or owing by such Lender (including, without limitation branches, agencies
or Affiliates of such Lender wherever located) to or for the credit or the
account of a Borrower against obligations and liabilities of such Borrower to
the Lenders hereunder, under the Notes, the other Credit Documents or otherwise,
irrespective of whether the Agent or the Lenders shall have made any demand
hereunder and although such obligations, liabilities or claims, or any of them,
may be contingent or unmatured, and any such set-off shall be deemed to have
been made immediately upon the occurrence of an Event of Default even though
such charge is made or entered on the books of such Lender subsequent thereto.

         11.3 BENEFIT OF AGREEMENT.

                  (a) Generally. This Credit Agreement shall be binding upon and
         inure to the benefit of and be enforceable by the respective successors
         and assigns of the parties hereto; provided that, except as set forth
         in Section 2.10, a Borrower may not assign and transfer any of its
         interests without the prior written consent of the Lenders; and
         provided further that the rights of each Lender to transfer, assign or
         grant participations in its rights and/or obligations hereunder shall
         be limited as set forth below in this Section 11.3.

                  (b) Assignments. Each Lender may assign to one or more
         Eligible Assignees all or a portion of its rights and obligations under
         this Credit Agreement (including, without limitation, all or a portion
         of its Loans, its Notes, and its Commitment); provided, however, that:

                           (i) each such assignment shall be to an Eligible
                  Assignee;

                           (ii) except in the case of an assignment to another
                  Lender or an assignment of all of a Lender's rights and
                  obligations under this Credit Agreement, any such partial
                  assignment shall be in an amount at least equal to $20,000,000
                  (or, if less, the remaining amount of the Commitment being
                  assigned by such Lender) and an integral multiple of
                  $1,000,000 in excess thereof; and

                           (iii) the parties to such assignment shall execute
                  and deliver to the Agent for its acceptance an Assignment
                  Agreement in substantially the form of Exhibit 11.3(b),
                  together with a processing fee from the assignor of $3,500.

         Upon execution, delivery, and acceptance of such Assignment Agreement,
         the assignee thereunder shall be a party hereto and, to the extent of
         such assignment, have the obligations, rights, and benefits of a Lender
         hereunder and the assigning Lender shall, to the extent of such
         assignment, relinquish its rights and be released from its obligations
         under this Credit Agreement. Upon the consummation of any assignment
         pursuant to this Section 11.3(b), the assignor, the Agent and the
         Borrowers shall make appropriate arrangements so that, if required, new
         Notes are issued to the assignor and the assignee. If the assignee is
         not incorporated under the laws of the United States of America or a
         state thereof, it shall deliver to the Borrowers and the Agent
         certification as to exemption from deduction or withholding of taxes in
         accordance with Section 4.4.

                  By executing and delivering an assignment agreement in
         accordance with this Section 11.3(b), the assigning Lender thereunder
         and the assignee thereunder shall be deemed to confirm to and agree
         with each other and the other parties hereto as follows: (A) such
         assigning Lender warrants that it is the legal and beneficial owner of
         the interest being assigned thereby free and clear of any adverse claim
         created by such assigning Lender and the assignee warrants that it is
         an Eligible Assignee; (B) except as set forth in clause (A) above, such
         assigning Lender makes no representation or warranty and assumes no
         responsibility with respect to any statements, warranties or
         representations


                                       50
<PAGE>   55

         made in or in connection with this Credit Agreement, any of the other
         Credit Documents or any other instrument or document furnished pursuant
         hereto or thereto, or the execution, legality, validity,
         enforceability, genuineness, sufficiency or value of this Credit
         Agreement, any of the other Credit Documents or any other instrument or
         document furnished pursuant hereto or thereto or the financial
         condition of the Borrowers or the performance or observance by the
         Borrowers of any of their obligations under this Credit Agreement, any
         of the other Credit Documents or any other instrument or document
         furnished pursuant hereto or thereto; (C) such assignee represents and
         warrants that it is legally authorized to enter into such assignment
         agreement; (D) such assignee confirms that it has received a copy of
         this Credit Agreement, the other Credit Documents and such other
         documents and information as it has deemed appropriate to make its own
         credit analysis and decision to enter into such assignment agreement;
         (E) such assignee will independently and without reliance upon the
         Agent, such assigning Lender or any other Lender, and based on such
         documents and information as it shall deem appropriate at the time,
         continue to make its own credit decisions in taking or not taking
         action under this Credit Agreement and the other Credit Documents; (F)
         such assignee appoints and authorizes the Agent to take such action on
         its behalf and to exercise such powers under this Credit Agreement or
         any other Credit Document as are delegated to the Agent by the terms
         hereof or thereof, together with such powers as are reasonably
         incidental thereto; and (G) such assignee agrees that it will perform
         in accordance with their terms all the obligations which by the terms
         of this Credit Agreement and the other Credit Documents are required to
         be performed by it as a Lender.

                  (c) Register. The Agent shall maintain a copy of each
         Assignment Agreement delivered to and accepted by it and a register for
         the recordation of the names and addresses of the Lenders and the
         Commitment of, and principal amount of the Loans owing to, each Lender
         from time to time (the "Register"). The entries in the Register shall
         be conclusive and binding for all purposes, absent manifest error, and
         the Borrowers, the Agent and the Lenders may treat each Person whose
         name is recorded in the Register as a Lender hereunder for all purposes
         of this Credit Agreement. The Register shall be available for
         inspection by the Borrowers or any Lender at any reasonable time and
         from time to time upon reasonable prior notice.

                  (d) Acceptance. Upon its receipt of an Assignment Agreement
         executed by the parties thereto, together with any Note subject to such
         assignment and payment of the processing fee, the Agent shall, if such
         Assignment Agreement has been completed and is in substantially the
         form of Exhibit 11.3(b) hereto, (i) accept such Assignment Agreement,
         (ii) record the information contained therein in the Register and (iii)
         give prompt notice thereof to the parties thereto.

                  (e) Participations. Each Lender may sell participations to one
         or more Persons in all or a portion of its rights, obligations or
         rights and obligations under this Credit Agreement (including all or a
         portion of its Commitment, its Notes and its Loans); provided, however,
         that (i) such Lender's obligations under this Credit Agreement shall


                                       51
<PAGE>   56

         remain unchanged, (ii) such Lender shall remain solely responsible to
         the other parties hereto for the performance of such obligations, (iii)
         the participant shall be entitled to the benefit of the yield
         protection provisions contained in Sections 4.1 through 4.4, inclusive,
         but shall not be entitled to receive any amount greater than such
         Lender would have been able to receive, and (iv) the Borrowers shall
         continue to deal solely and directly with such Lender in connection
         with such Lender's rights and obligations under this Credit Agreement,
         and such Lender shall retain the sole right to enforce the obligations
         of the Borrowers relating to its Loans and its Notes and to approve any
         amendment, modification, or waiver of any provision of this Credit
         Agreement (other than amendments, modifications, or waivers decreasing
         the amount of principal of or the rate at which interest is payable on
         such Loans or Notes, extending any scheduled principal payment date or
         date fixed for the payment of interest on such Loans or Notes, or
         extending its Commitment).

                  (f) Nonrestricted Assignments. Notwithstanding any other
         provision set forth in this Credit Agreement, any Lender may at any
         time assign and pledge all or any portion of its Loans and its Notes to
         any Federal Reserve Bank as collateral security pursuant to Regulation
         A and any Operating Circular issued by such Federal Reserve Bank. No
         such assignment shall release the assigning Lender from its obligations
         hereunder.

                  (g) Information. Any Lender may furnish any information
         concerning the Borrowers in the possession of such Lender from time to
         time to assignees and participants (including prospective assignees and
         participants).

                  (h) Costs Associated With Assignment. All reasonable
         out-of-pocket costs and expenses of the Agent, the assigning Lender and
         the assignee Lender associated with the preparation, execution and
         delivery of an Assignment Agreement and any documents related thereto
         (including, without limitation, the reasonable fees and disbursements
         of counsel) shall be paid by the assigning Lender (or such other Person
         as agreed to by the assigning Lender, the assignee Lender and the
         Agent).

         11.4 NO WAIVER; REMEDIES CUMULATIVE.

         No failure or delay on the part of the Agent or any Lender in
exercising any right, power or privilege hereunder or under any other Credit
Document and no course of dealing between the Borrowers and the Agent or any
Lender shall operate as a waiver thereof; nor shall any single or partial
exercise of any right, power or privilege hereunder or under any other Credit
Document preclude any other or further exercise thereof or the exercise of any
other right, power or privilege hereunder or thereunder. The rights and remedies
provided herein are cumulative and not exclusive of any rights or remedies which
the Agent or any Lender would otherwise have. No notice to or demand on the
Borrowers in any case shall entitle the Borrowers to any other or further notice
or demand in similar or other circumstances or constitute a waiver of the rights
of the Agent or the Lenders to any other or further action in any circumstances
without notice or demand.

         The Borrowers agree to: (i) pay all reasonable out-of-pocket costs and

with (A) the negotiation, preparation, execution and delivery, syndication and
administration of this Credit Agreement and the other Credit Documents and the

(iii) indemnify the Agent, BAS and each Lender, its officers, directors,
employees, representatives and agents from and hold each of them harmless
against any and all losses, liabilities, claims, damages or expenses incurred by
any of them as a result of, or arising out of, or in any way related to, or by
reason of, any investigation, litigation or other proceeding (whether or not the
Agent, BAS or any Lender is a party thereto) related to the entering into and/or
performance of any Credit Document or the use of proceeds of any Loans
(including other extensions of credit) hereunder or the consummation of any
other transactions contemplated in any Credit Document, including, without
limitation, the reasonable fees and disbursements of counsel and settlement
costs incurred in connection with any such investigation, litigation or other
proceeding (but excluding any such losses, liabilities, claims, damages or

         11.6 AMENDMENTS, WAIVERS AND CONSENTS.

         Neither this Credit Agreement, nor any other Credit Document nor any of
the terms hereof or thereof may be amended, changed, waived, discharged or
terminated unless such amendment, change, waiver, discharge or termination is in
writing and signed by the Required Lenders and the Borrowers; provided that no
such amendment, change, waiver, discharge or termination shall without the
consent of each Lender affected thereby:

                  (a) extend the Maturity Date, or postpone or extend the time
         for any payment or prepayment of principal;

                  (b) reduce the rate or extend the time of payment of interest
         (other than as a result of waiving the applicability of any

         amounts payable hereunder;

                  (c) reduce or waive the principal amount of any Loan;


                                       53
<PAGE>   58

                  (d) increase or extend the Commitment of a Lender (it being
         understood and agreed that a waiver of any Default or Event of Default
         or a waiver of any mandatory reduction in the Commitments shall not
         constitute a change in the terms of any Commitment of any Lender);

                  (e) except as permitted by Section 2.10, consent to the
         assignment or transfer by a Borrower of any of its rights and
         obligations under (or in respect of) the Credit Documents or release a
         Borrower from its obligations under the Credit Documents;

                  (f) amend, modify or waive any provision of this Section 11.6
         or Section 3.6, 3.8, 9.1(a), 11.2, 11.3 or 11.5; or

                  (g) reduce any percentage specified in, or otherwise modify,
         the definition of Required Lenders.

No amendment or change that affects the application of prepayments pursuant to
Section 3.2(c) or the allocation of payments between the Revolving-A Loans and
the Revolving-B Loans shall be effective unless Lenders holding in the aggregate
at least 51% of the Revolving-A Loan Commitment and at least 51% of the
Revolving-B Loan Commitment shall consent to such amendment or change in
allocation of payments.

No provision of Section 10 may be amended or modified without the consent of the
Agent.

Notwithstanding the fact that the consent of all the Lenders is required in
certain circumstances as set forth above, (x) each Lender is entitled to vote as
such Lender sees fit on any reorganization plan that affects the Loans, and each
Lender acknowledges that the provisions of Section 1126(c) of the Bankruptcy
Code supersede the unanimous consent provisions set forth herein and (y) the
Required Lenders may consent to allow the Borrowers to use cash collateral in
the context of a bankruptcy or insolvency proceeding.

         11.7 COUNTERPARTS/TELECOPY.

         This Credit Agreement may be executed in any number of counterparts,
each of which where so executed and delivered shall be an original, but all of
which shall constitute one and the same instrument. Delivery of executed
counterparts by telecopy shall be as effective as an original and shall
constitute a representation that an original will be delivered.

         11.8 HEADINGS.

         The headings of the sections and subsections hereof are provided for
convenience only and shall not in any way affect the meaning or construction of
any provision of this Credit Agreement.

<PAGE>   59

         11.9 DEFAULTING LENDER.

         Each Lender understands and agrees that if such Lender is a Defaulting
Lender then it shall not be entitled to vote on any matter requiring the consent
of the Required Lenders or to object to any matter requiring the consent of all
the Lenders; provided, however, that all other benefits and obligations under
the Loan Documents shall apply to such Defaulting Lender.

         11.10 SURVIVAL OF INDEMNIFICATION AND REPRESENTATIONS AND WARRANTIES.

         All indemnities set forth herein and all representations and warranties
made herein shall survive the execution and delivery of this Credit Agreement,
the making of the Loans, and the repayment of the Loans and other obligations
and the termination of the Commitments hereunder.

         11.11 GOVERNING LAW; VENUE.

                  (a) THIS CREDIT AGREEMENT AND THE OTHER CREDIT DOCUMENTS AND
         THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER AND THEREUNDER
         SHALL BE GOVERNED BY AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH
         THE LAWS OF THE STATE OF NEW YORK. Any legal action or proceeding with
         respect to this Credit Agreement or any other Credit Document may be
         brought in the courts of the State of New York, or of the United States
         for the Southern District of New York, and, by execution and delivery
         of this Credit Agreement, each Borrower hereby irrevocably accepts for
         itself and in respect of its property, generally and unconditionally,
         the jurisdiction of such courts. Each Borrower further irrevocably
         consents to the service of process out of any of the aforementioned
         courts in any such action or proceeding by the mailing of copies
         thereof by registered or certified mail, postage prepaid, to it at the
         address for notices pursuant to Section 11.1, such service to become
         effective 30 days after such mailing. Nothing herein shall affect the
         right of a Lender to serve process in any other manner permitted by law
         or to commence legal proceedings or to otherwise proceed against a
         Borrower in any other jurisdiction.

                  (b) Each Borrower hereby irrevocably waives any objection
         which it may now or hereafter have to the laying of venue of any of the
         aforesaid actions or proceedings arising out of or in connection with
         this Credit Agreement or any other Credit Document brought in the
         courts referred to in subsection (a) hereof and hereby further
         irrevocably waives and agrees not to plead or claim in any such court
         that any such action or proceeding brought in any such court has been
         brought in an inconvenient forum.

         11.12 WAIVER OF JURY TRIAL; WAIVER OF CONSEQUENTIAL DAMAGES.

         EACH OF THE PARTIES TO THIS CREDIT AGREEMENT HEREBY IRREVOCABLY WAIVES
ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR


                                       55
<PAGE>   60

COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS CREDIT AGREEMENT, ANY OF THE
OTHER CREDIT DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED HEREBY. Each Borrower
agrees not to assert any claim against the Agent, any Lender, any of their
Affiliates, or any of their respective directors, officers, employees, attorneys
or agents, on any theory of liability, for special, indirect, consequential or
punitive damages arising out of or otherwise relating to any of the transactions
contemplated hereby or by the other Credit Documents.

         11.13 SEVERABILITY.

         If any provision of any of the Credit Documents is determined to be
illegal, invalid or unenforceable, such provision shall be fully severable and
the remaining provisions shall remain in full force and effect and shall be
construed without giving effect to the illegal, invalid or unenforceable
provisions.

         11.14 FURTHER ASSURANCES.

         Each Borrower agrees, upon the request of the Agent, to promptly take
such actions, as reasonably requested, as are necessary to carry out the intent
of this Credit Agreement and the other Credit Documents.

         11.15 ENTIRETY.

         This Credit Agreement together with the other Credit Documents
represent the entire agreement of the parties hereto and thereto, and supersede
all prior agreements and understandings, oral or written, if any, including any
commitment letters or correspondence relating to the Credit Documents or the
transactions contemplated herein and therein.

         11.16 BINDING EFFECT; CONTINUING AGREEMENT.

                  (a) This Credit Agreement shall become effective at such time
         when all of the conditions set forth in Section 5.1 have been satisfied
         or waived by the Lenders and it shall have been executed by the
         Borrowers, the Agent and the Lenders, and thereafter this Credit
         Agreement shall be binding upon and inure to the benefit of the
         Borrowers, the Agent and each Lender and their respective successors
         and permitted assigns.

                  (b) This Credit Agreement shall be a continuing agreement and
         shall remain in full force and effect until all Loans, interest, fees
         and other Borrowers Obligations have been paid in full and all
         Commitments have been terminated. Upon such termination, the Borrowers
         shall have no further obligations (other than those provisions that
         expressly survive the termination thereof) under the Credit Documents;
         provided that should any payment, in whole or in part, of the Borrowers
         Obligations be rescinded or otherwise required to be restored or
         returned by the Agent or any Lender, whether as a result of any
         proceedings in bankruptcy or reorganization or otherwise, then the
         Credit Documents shall automatically be reinstated and all amounts
         required to be restored or returned and all costs and expenses incurred
         by the Agent or any Lender in connection therewith shall be deemed
         included as part of the Borrowers Obligations.

         (a) During the Term of this Agreement the Lender agrees, on the terms
and conditions contained in this Agreement, to make Loans to the Borrower at any
time prior to the Termination Date in an aggregate amount not exceeding at any
one time outstanding the Commitment in effect at the time the Loans are made.
The Borrower shall repay Loans in accordance with Section 2.3 and may reborrow
under this Section 2.1(a) at any time.

         (b) Any other provision of this Agreement to the contrary
notwithstanding, the Lender shall not be obligated to make a Loan to the

<PAGE>   7

terms, conditions, covenants or provisions of this Agreement including, without
limitation, the terms and conditions contained in Section 3 hereof.

         2.2  Method of Borrowing.

         (a) With respect to each Loan made pursuant to Section 2.1 hereof, the
Borrower shall give the Lender a notice of borrowing notifying the Lender of its
request to borrow hereunder, which notice will specify (i) the date of the Loan,
which date shall be a Business Day, and (ii) the principal amount of the Loan,
which shall be $100,000 or a greater integral multiple thereof. The notice of
borrowing shall be written or electronic communication.

         (b) If the Borrower gives the notice required by Section 2.2(a) with
respect to any Loan before 10:00 a.m. (Eastern Time), the Lender will disburse
the proceeds of the Loan to the Borrower in immediately available funds on the
date of such notice, or such other day as indicated on the request. The Lender
will disburse all Loans to the Borrower in such account as shall be designated
by the Borrower in the applicable notice of borrowing.

         2.3  Repayment of the Loans.

         (a) The Borrower agrees that it shall repay all Loans on or before the
Termination Date.

         (b) The Borrower may repay the outstanding principal amount of Loans in
whole or in part on any Business Day upon notice to the Lender given not later

         2.5  Interest Rate and Payments.

         (a) Loans shall bear interest on the outstanding principal amount
thereof, for each day during which any Loans are outstanding, at a rate per
annum equal to the Base Rate as in effect from time to time. Interest on Loans
shall be payable monthly in arrears and on the Termination Date. The Lender will
notify the Borrower in writing or electronically, not later than three days
after the end of each month, of the amount of interest payable hereunder with
respect to Loans, which notice will set forth in reasonable detail the
calculation of such amount. The Borrower agrees that it shall pay each monthly
installment of interest within five Business Days after the date on which it
receives such notice.

         (b) To the extent permitted by law, overdue interest on the Loans shall
bear interest, payable on demand of the Lender, for each day until paid at a
rate per annum equal to the Base Rate plus 2%.

         2.6  Reduction and Cancellation of the Commitment. The Commitment shall
terminate on the Termination Date, and any Loans then outstanding (together with
accrued but unpaid interest thereon) shall be repaid in full on such date.

         2.7  General Provisions as to Payments. Subject to the provisions of
Section 2.3(b), the Borrower shall make each payment of principal of, and
interest on, the Loans in funds immediately available in the account that the
Lender shall designate. Whenever any payment of principal of, or interest on,
the Loans shall be due on a day which is not a Business Day, the date for
payment thereof shall be extended to the next succeeding Business Day. If the
date for any payment of principal is extended by operation of law or otherwise,
interest shall be payable for such extended time at a rate per annum equal to
the Base Rate.

         2.8  Computation of Interest and Fees.  Interest on Loans  shall be
computed for each day on the basis of a year of 360 days.

         2.9  No Deduction.  All amounts payable by the Borrower under this
Agreement are payable without deduction or set-off unless specifically agreed to
by the Lender in writing.

         2.10  Use of Proceeds. The proceeds of Loans will be employed by the
Borrower for general corporate purposes including, without limitation, as
working capital for the Borrower and its Subsidiaries.

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

         The obligation of the Lender to make each Loan hereunder is subject to
the performance by the Borrower of all its obligations under this Agreement and
to the satisfaction of the following further conditions:


                                       5

         (a) receipt by the Lender of a notice of borrowing from the Borrower
required by Section 2.2(a) hereof;

         (b) the fact that immediately after the making of the Loan no Default
or Event of Default shall have occurred and be continuing;

Each notice of borrowing and each borrowing by the Borrower hereunder shall be

believes, acting in good faith, that the conditions set forth in (b) and (c)
above cannot or would not be satisfied, the Lender will have no obligation to
make the applicable Loan.


                   SECTION 4. REPRESENTATIONS AND WARRANTIES.
                              ------------------------------

company duly organized, validly existing and in good standing under the laws of
the jurisdiction of its organization, has full power and authority to carry on
its business as now being conducted and to own its properties and is duly
licensed or qualified and in good standing as a foreign limited liability

Material Adverse Effect. The Borrower is in compliance with its Limited
Liability Company Certificate, limited liability company agreement and all other
organizational or governing documents.

         4.2  Corporate Authorization. The execution, delivery and performance
by the Borrower of this Agreement are within the Borrower's corporate power and

performance of its obligations under, this Agreement do not, and consummation of
the transactions contemplated hereby will not, result in:



                                       6
<PAGE>   10

         (a) a violation of or a conflict with any provision of the Limited
Liability Company Certificate, limited liability company agreement or any other
organizational or governing document of the Borrower;

         (b) a material breach or default under any provision of any contract,
agreement, lease, commitment, license, franchise or permit to which the Borrower
is a party or by which any property of the Borrower is bound;

         (c) a material violation of any statute, rule, regulation, ordinance,
order, judgment, writ, injunction, decree or award of any judicial,
administrative, governmental or other authority or of any arbitrator; or

         (d) an imposition on the business of the Borrower or on any of its
properties of any Lien.

         4.5  Financial Statements. The combined financial statements of DEFS
Corp. and affiliates which have previously been delivered to the Lender, fairly
present in conformity with Generally Accepted Accounting Principles, the
combined financial position of DEFS Corp. and affiliates at the dates and the
combined results of operations for the periods ended, as of the dates for which
they are given.

         4.6  Litigation. There is no action, suit, litigation or proceeding at
law or in equity or by or before any Governmental Authority now pending against
or, to the knowledge of the Borrower, threatened against the Borrower or any of
its Subsidiaries or any of their respective Properties, an adverse decision in
which could reasonably be expected to have a Material Adverse Effect, except as
disclosed in the Form S-1 Registration Statement (File No. 333-32502), filed by
DEFS Corp. with the Securities and Exchange Commission.

         4.7  No Default. None of the Borrower or the Borrower's Subsidiaries
(i) is in breach or violation of any of the terms, covenants, conditions or
provisions of any of its Obligations such as reasonably could be expected to
have a Material Adverse Effect; or (ii) has done or omitted to do anything
which, with the giving of notice or lapse of time, or both, would constitute a
material default under any of its obligations or reasonably could be expected to
have a Material Adverse Effect.

         4.8  No Event of Default. No Event of Default or other material event
which, with the giving of notice or lapse of time, or both, would constitute an
Event of Default has occurred and is continuing.

         4.9  Adverse Change.  There have been no material adverse changes in
the financial condition, results of operations or business of the Borrower and
its Subsidiaries taken as a whole since December 31, 1999.

         4.10  Liens. Except with respect to certain title matters currently
being resolved between the Borrower and Phillips Petroleum Company, of which the
Borrower has made the Lender aware, the Borrower and the Borrower's Subsidiaries
have good and marketable title to


                                       7
<PAGE>   11

each of their respective Properties, free and clear of all material Liens,
except for Liens arising in the ordinary course of their businesses and except
for Liens, if any, now existing (i) on any asset of any entity at the time such
entity became a Subsidiary and not created in contemplation of such event; (ii)
on any asset securing Debt incurred or assumed for the purpose of financing all
or any part of the cost of acquiring such asset; (iii) on any asset of any
entity which existed at the time such entity was merged into or consolidated
with the Borrower or a Subsidiary and not created in contemplation of such
event; (iv) on any asset prior to the acquisition thereof by the Borrower or a
Subsidiary and not created in contemplation of such acquisition; (v) which arose
out of the refinancing, extension, renewal or refunding of any Debt secured by
any Lien permitted by any of the foregoing clauses of this section; or (vi)
which arose pursuant to any order of attachment, distraint or similar legal
process in connection with court proceedings so long as the execution or other
enforcement thereof is effectively stayed and the claims secured thereby are
being contested in good faith by appropriate proceedings. The obligations of the
Borrower under this Agreement rank at least pari passu to all other debt of the
Borrower.

         4.11  Compliance with Laws. The Borrower and each Subsidiary is in
compliance in all material respects with all applicable laws, ordinances, rules,
regulations and requirements of governmental authorities (including, without
limitation, ERISA and Environmental Laws) except where (i) non-compliance would
not have a Material Adverse Effect, or (ii) the necessity of compliance
therewith is contested in good faith by appropriate proceedings.

         4.12  Taxes. All federal, state and other income tax returns of the
Borrower and each of the Borrower's Subsidiaries required by law to be filed
have been duly filed, and all federal, state and other taxes, assessments and
other governmental charges or levies upon the Borrower and each of the
Borrower's Subsidiaries and any of their respective Properties, income, profits
and assets, which are due and payable, have been paid, except such as are being
contested in good faith or which, if taken in the aggregate, reasonably would
not be expected to have a Material Adverse Effect.

         4.13  Labor Matters. There are no strikes or other labor disputes,
grievances, charges or complaints with respect to any employee or group of
employees pending or, to the best knowledge of the Borrower, threatened against
the Borrower or any of the Borrower's Subsidiaries which reasonably could be
expected to have a Material Adverse Effect.

         4.14  Completeness. None of the statements of the Borrower contained in
this Agreement or in any certificate or written statement furnished by the
Borrower to the Lender pursuant hereto when made (as limited or qualified in
such documents) contained any untrue statement of a material fact or omitted to
state a material fact necessary to make the statements contained therein not
misleading. There is no fact known to the Borrower which the Borrower has not
disclosed to the Lender which reasonably could be expected to have a Material
Adverse Effect.

<PAGE>   4


the meaning of section 424(f) of the Code as a "subsidiary corporation" with
respect to the Corporation.

                  3. SHARES OF COMMON STOCK SUBJECT TO THE PLAN

3.1. NUMBER OF SHARES. Subject to the following provisions of this Section 3,
the aggregate number of shares of Common Stock that may be issued pursuant to
all Awards under the Plan is 4,000,000 shares of Common Stock; provided,
however, that no more than 400,000 shares of Common Stock may be issued pursuant
to all Awards of Restricted Stock, Performance Awards or Phantom Stock under the
Plan. The shares of Common Stock to be delivered under the Plan will be made
available from authorized but unissued shares of Common Stock or Common Stock
previously issued and outstanding and reacquired by the Corporation. If any
share of Common Stock that is the subject of an Award is not issued and ceases
to be issuable for any reason, or is forfeited, cancelled or returned to the
Corporation for failure to satisfy vesting requirements or upon the occurrence
of other forfeiture events, such share of Common Stock will no longer be charged
against the foregoing maximum share limitations and may again be made subject to
Awards under the Plan pursuant to such limitations.

3.2. ADJUSTMENTS. If there shall occur any recapitalization, reorganization,
reclassification, merger, consolidation, combination, stock dividend, stock
split, reverse stock split, split-up, split-off, spin-off or other distribution
with respect to the shares of Common Stock, or any similar corporate transaction
or event in respect of the Common Stock, then the Committee shall, in the manner
and to the extent that it deems appropriate and consistent with the terms of
this Plan, cause a proportionate adjustment to be made in (a) the maximum
numbers and kind of shares provided in Section 3.1 hereof, (b) the number and
kind of shares of Common Stock, share units, or other rights or property
(including, without limitation, cash) subject to the then-outstanding Awards,
(c) the price for each share or unit or other right subject to then outstanding
Awards without change in the aggregate purchase price or value as to which such
Awards remain exercisable or subject to restrictions, (d) the performance
targets or goals appropriate to any outstanding Performance Awards, or (e) any
other terms of an Award that are affected by the event.

                          4. ADMINISTRATION OF THE PLAN

4.1. COMMITTEE MEMBERS. Except as provided in Section 4.4 hereof, the Plan will
be administered by the Committee which, to the extent deemed necessary or
appropriate by the Board, will consist of two or more persons who satisfy the
requirements for a "nonemployee director" under Rule 16b-3 promulgated under the
Exchange Act. The Committee may exercise such powers and authority as may be
necessary or appropriate for the Committee to carry out its functions as
described in the Plan. No member of the Committee will be liable for any action
or determination made in good faith by the Committee with respect to the Plan or
any Award under it.

4.2. DISCRETIONARY AUTHORITY. Subject to the express limitations of the Plan,
the Committee has authority in its discretion to determine the Eligible Persons
to whom, and



                                       4
<PAGE>   5


the time or times at which, Awards may 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 an Award will become vested,
exercisable or payable, the performance criteria, performance goals and other
conditions of an Award, and the duration of the Award. The Committee also has
discretionary authority to interpret the Plan, to make all factual
determinations under the Plan, and to determine the terms and provisions of the
respective Award Agreements and to make all other determinations necessary or
advisable for Plan administration. The Committee has authority to prescribe,
amend, and rescind rules and regulations relating to the Plan. All
interpretations, determinations, and actions by the Committee will be final,
conclusive, and binding upon all parties.

4.3. CHANGES TO AWARDS. The Committee shall have the authority to effect, at any
time and from time to time, with the consent of the affected Participants, (a)
the cancellation of any or all outstanding Awards and the grant in substitution
therefor of new Awards covering the same or different numbers of shares of
Common Stock and having an exercise or base price which may be the same as or
different than the exercise or base price of the cancelled Awards or (b) the
amendment of the terms of any and all outstanding Awards. The Committee may in
its discretion accelerate the vesting or exercisability of an Award at any time
or on the basis of any specified event.

4.4. DELEGATION OF AUTHORITY. The Committee shall have the right, from time to
time, to delegate to one or more officers of the Corporation the authority of
the Committee to grant and determine the terms and conditions of Awards under
the Plan, subject to such limitations as the Committee shall determine;
provided, however, that no such authority may be delegated with respect to
Awards made to any member of the Board.

4.5. AWARDS TO INDEPENDENT DIRECTORS. An Award to an Independent Director under
the Plan shall be approved by the Board. With respect to Awards to Independent
Directors, all rights, powers and authorities vested in the Committee under the
Plan shall instead be exercised by the Board, and all provisions of the Plan
relating to the Committee shall be interpreted in a manner consistent with the
foregoing by treating any such reference as a reference to the Board for such
purpose.

                            5. ELIGIBILITY AND AWARDS

         All Eligible Persons are eligible to be designated by the Committee to
receive an Award under the Plan. The Committee has authority, in its sole
discretion, to determine and designate from time to time those Eligible Persons
who are to be granted Awards, the types of Awards to be granted and the number
of shares or units subject to the Awards that are granted under the Plan. Each
Award will be evidenced by an Award Agreement as described in Section 13 hereof
between the Corporation and the Participant that shall include the terms and
conditions consistent with the Plan as the Committee may determine.



                                       5

                                6. STOCK OPTIONS

6.1. GRANT OF OPTION. An Option may be granted to any Eligible Person selected
by the Committee; provided, however, that only Employees shall be eligible for
Awards of Incentive Stock Options. Each Option shall be designated, at the
discretion of the Committee, as an Incentive Stock Option or a Nonqualified
Stock Option.

6.2. EXERCISE PRICE. The exercise price of the Option shall be determined by the
Committee; provided, however, that the exercise price per share of an Option
shall not be less than one hundred percent (100%) of the Fair Market Value per
share of the Common Stock on the Date of Grant.

6.3. VESTING; TERM OF OPTION. The Committee, in its sole discretion, shall
prescribe in the Award Agreement the time or times at which, or the conditions
upon which, an Option or portion thereof shall become vested and exercisable,
and may accelerate the exercisability of any Option at any time. An Option may
become vested and exercisable upon a Participant's retirement, death,
disability, Change in Control or other event, to the extent provided in an Award
Agreement. The period during which a vested Option may be exercised shall be ten
years from the Date of Grant, unless a shorter exercise period is specified by
the Committee in an Award Agreement, and subject to such limitations as may
apply under an Award Agreement relating to the termination of a Participant's
employment or other service with the Corporation or any Subsidiary.

6.4. OPTION EXERCISE; WITHHOLDING. Subject to such terms and conditions as shall
be specified in an Award Agreement, an Option may be exercised in whole or in
part at any time during the term thereof by written notice to the Corporation
together with payment of the aggregate exercise price therefor. Payment of the
exercise price shall be made (a) in cash or by cash equivalent, (b) at the
discretion of the Committee, in shares of Common Stock acceptable to the
Committee, valued at the Fair Market Value of such shares on the date of
exercise, (c) at the discretion of the Committee, by a delivery of a notice that
the Participant has placed a market sell order (or similar instruction) with a
broker with respect to shares of Common Stock then issuable upon exercise of the
Option, and that the broker has been directed to pay a sufficient portion of the
net proceeds of the sale to the Corporation in satisfaction of the Option
exercise price (conditioned upon the payment of such net proceeds), (d) at the
discretion of the Committee, by a combination of the methods described above or
(e) by such other method as may be approved by the Committee and set forth in
the Award Agreement. In addition to and at the time of payment of the exercise
price, the Participant shall pay to the Corporation the full amount of any and
all applicable income tax and employment tax amounts required to be withheld in
connection with such exercise, payable under one or more of the methods
described above for the payment of the exercise price of the Options as may be
approved by the Committee.

6.5. LIMITED TRANSFERABILITY. Solely to the extent permitted by the Committee in
an Award Agreement and subject to such terms and conditions as the Committee
shall specify, a Nonqualified Stock Option (but not an Incentive Stock Option)
may be



                                       6
<PAGE>   7


transferred to members of the Participant's immediate family (as determined by
the Committee) or to trusts, partnerships or corporations whose beneficiaries,
members or owners are members of the Participant's immediate family, and/or to
such other persons or entities as may be approved by the Committee in advance
and set forth in an Award Agreement, in each case subject to the condition that
the Committee be satisfied that such transfer is being made for estate or tax
planning purposes or for gratuitous or donative purposes, without consideration
(other than nominal consideration) being received therefor. Except to the extent
permitted by the Committee in accordance with the foregoing, an Option shall be
nontransferable otherwise than by will or by the laws of descent and
distribution, and shall be exercisable during the lifetime of a Participant only
by such Participant.

6.6.     ADDITIONAL RULES FOR INCENTIVE STOCK OPTIONS.

         (a) ANNUAL LIMITS. To the extent that the aggregate fair market value
(determined at the time the respective Incentive Stock Option is granted) of
Common Stock with respect to which Incentive Stock Options are exercisable for
the first time by an individual during any calendar year under the Plan, and any
other stock option plans of the Corporation, any Subsidiary or any parent
corporation, exceeds $100,000 (determined in accordance with section 422(d) of
the Code), such Incentive Stock Options shall be treated as Nonqualified Stock
Options. The Committee shall determine, in accordance with applicable provisions
of the Code, Treasury Regulations and other administrative pronouncements, which
of a Participant's Incentive Stock Options shall be treated as Nonqualified
Stock Options because of such limitation and shall notify the Participant of
such determination as soon as practicable after such determination.

         (b) TERMINATION OF EMPLOYMENT. An Award Agreement for an Incentive
Stock Option may provide that such Option may be exercised not later than 3
months following termination of employment of the Participant with the
Corporation and all Subsidiaries, subject to special rules relating to death and
disability, as and to the extent determined by the Committee to be appropriate
with regard to the requirements of section 422 of the Code and Treasury
Regulations thereunder.

         (c) OTHER TERMS AND CONDITIONS; NONTRANSFERABILITY. Any Incentive Stock
Option granted hereunder shall contain such additional terms and conditions, not
inconsistent with the terms of this Plan, as are deemed necessary or desirable
by the Committee, which terms, together with the terms of this Plan, shall be
intended and interpreted to cause such Incentive Stock Option to qualify as an
"incentive stock option" under section 422 of the Code. Such terms shall
include, if applicable, limitations on Incentive Stock Options granted to
ten-percent owners of the Corporation. An Award Agreement for an Incentive Stock
Option may provide that such Option shall be treated as a Nonqualified Stock
Option to the extent that certain requirements applicable to "incentive stock
options" under the Code shall not be satisfied. An Incentive Stock Option shall
be nontransferable otherwise than by will or by the laws of descent and
distribution, and shall be exercisable during the lifetime of a Participant only
by such Participant.



                                       7
<PAGE>   8


         (d) DISQUALIFYING DISPOSITIONS. If shares of Common Stock acquired by
exercise of an Incentive Stock Option are disposed of within two years following
the Date of Grant or one year following the transfer of such shares to the
Participant upon exercise, the Participant shall, promptly following such
disposition, notify the Corporation in writing of the date and terms of such
disposition and provide such other information regarding the disposition as the
Committee may reasonably require.

                          7. STOCK APPRECIATION RIGHTS

7.1. GRANT OF SARS. A Stock Appreciation Right granted to a Participant is an
Award in the form of a right to receive, upon surrender of the right, but
without other payment, an amount based on appreciation in the Fair Market Value
of the Common Stock over a base price established for the Award, exercisable at
such time or times and upon conditions as may be approved by the Committee.

7.2. TANDEM SARS. A Stock Appreciation Right may be granted in connection with
an Option, either at the time of grant or at any time thereafter during the term
of the Option. An SAR granted in connection with an Option will entitle the
holder, upon exercise, to surrender such Option or any portion thereof to the
extent unexercised, with respect to the number of shares as to which such SAR is
exercised, and to receive payment of an amount computed as described in Section
7.4 hereof. Such Option will, to the extent and when surrendered, cease to be
exercisable. An SAR granted in connection with an Option hereunder will have a
base price per share equal to the per share exercise price of the Option, will
be exercisable at such time or times, and only to the extent, that a related
Option is exercisable, and will expire no later than the related Option expires.

7.3. FREESTANDING SARS. A Stock Appreciation Right may be granted without
relationship to an Option and, in such case, will be exercisable as determined
by the Committee, but in no event after 10 years from the Date of Grant. The
base price of an SAR granted without relationship to an Option shall be
determined by the Committee in its sole discretion; provided, however, that the
base price per share of a freestanding SAR shall not be less than one hundred
percent (100%) of the Fair Market Value of the Common Stock on the Date of
Grant.

7.4. PAYMENT OF SARS. An SAR will entitle the holder, upon exercise of the SAR,
to receive payment of an amount determined by multiplying: (a) the excess of the
Fair Market Value of a share of Common Stock on the date of exercise of the SAR
over the base price of such SAR, by (b) the number of shares as to which such
SAR will have been exercised. Payment of the amount determined under the
foregoing may be made, in the discretion of the Committee, in cash, in shares of
Common Stock valued at their Fair Market Value on the date of exercise, or in a
combination of cash and shares of Common Stock.

                               8. RESTRICTED STOCK

8.1. GRANTS OF RESTRICTED STOCK. An Award of Restricted Stock to a Participant
represents shares of Common Stock that are issued subject to such restrictions
on transfer and other incidents of ownership and such forfeiture conditions as
the Committee may determine. The Committee may, in connection with an Award of
Restricted Stock, require the payment of a specified purchase price.

8.2. VESTING REQUIREMENTS. The restrictions imposed on an Award of Restricted
Stock shall lapse in accordance with the vesting requirements specified by the
Committee in the Award Agreement. Such vesting requirements may be based on the
continued employment of the Participant with the Corporation or its Subsidiaries
for a specified time period or periods, provided that any such restriction shall
not be scheduled to lapse in its entirety earlier than the first anniversary of
the Date of Grant. Such vesting requirements may also be based on the attainment
of specified business goals or measures established by the Committee in its sole
discretion.

8.3. RESTRICTIONS. Shares of Restricted Stock may not be transferred, assigned
or subject to any encumbrance, pledge or charge until all applicable
restrictions are removed or expire or unless otherwise allowed by the Committee.
The Committee may require the Participant to enter into an escrow agreement
providing that the certificates representing Restricted Stock granted or sold
pursuant to the Plan will remain in the physical custody of an escrow holder
until all restrictions are removed or expire. Failure to satisfy any applicable
restrictions shall result in the subject shares of Restricted Stock being
forfeited and returned to the Corporation, with any purchase price paid by the
Participant to be refunded, unless otherwise provided by the Committee. The
Committee may require that certificates representing Restricted Stock granted
under the Plan bear a legend making appropriate reference to the restrictions
imposed.

8.4. RIGHTS AS SHAREHOLDER. Subject to the foregoing provisions of this Section
8 and the applicable Award Agreement, the Participant will have all rights of a
shareholder with respect to shares of Restricted Stock granted to him, including
the right to vote the shares and receive all dividends and other distributions
paid or made with respect thereto, unless the Committee determines otherwise at
the time the Restricted Stock is granted, as set forth in the Award Agreement.

8.5. SECTION 83(b) ELECTION. The Committee may provide in an Award Agreement
that the Award of Restricted Stock is conditioned upon the Participant making an
election, or refraining from making an election, with respect to the Award under
section 83(b) of the Code. Irrespective of whether an Award is so conditioned,
if a Participant makes an election pursuant to section 83(b) of the Code with
respect to an Award of Restricted Stock, the Participant shall be required to
promptly file a copy of such election with the Corporation.

                              9. PERFORMANCE AWARDS

9.1. GRANT OF PERFORMANCE AWARDS. The Committee may grant Performance Awards
under the Plan, which shall be represented by units denominated on the Date of
Grant either in shares of Common Stock (Performance Shares) or in specified
dollar amounts (Performance Units). At the time a Performance Award is granted,
the Committee shall determine, in its sole discretion, one or more performance
periods and performance goals to be achieved during the applicable performance
periods, as well as such other restrictions and conditions as the Committee
deems appropriate. In the case of Performance Units, the Committee shall also
determine a target unit value or a range of unit values for each Award. No
performance period shall exceed ten years from the Date of Grant. The
performance goals applicable to a Performance Award grant may be subject to such
later revisions as the Committee shall deem appropriate to reflect significant
unforeseen events such as changes in law, accounting practices or unusual or
nonrecurring items or occurrences.

9.2. PAYMENT OF PERFORMANCE AWARDS. At the end of the performance period, the
Committee shall determine the extent to which performance goals have been
attained or a degree of achievement between minimum and maximum levels in order
to establish the level of payment to be made, if any, and shall determine if
payment is to be made in the form of cash or shares of Common Stock (valued at
their Fair Market Value at the time of payment) or a combination of cash and
shares of Common Stock. Payments of Performance Awards shall generally be made
as soon as administratively practicable following the end of the performance
period.

                                10. PHANTOM STOCK

10.1. GRANT OF PHANTOM STOCK. Phantom Stock is an Award to a Participant of a
number of hypothetical share units with respect to shares of Common Stock, with
an initial value based on the Fair Market Value of the Common Stock on the Date
of Grant. Phantom Stock shall be subject to such restrictions and conditions as
the Committee shall determine. On the Date of Grant, the Committee shall
determine, in its sole discretion, the installment or other vesting period of
the Phantom Stock and the maximum value of the Phantom Stock, if any. No vesting
period shall exceed 10 years from the Date of Grant. An Award of Phantom Stock
may be granted, at the discretion of the Committee, together with an Award of
Dividend Equivalent rights for the same number of shares covered thereby.

10.2. PAYMENT OF PHANTOM STOCK. Upon the vesting date or dates applicable to
Phantom Stock granted to a Participant, an amount equal to the Fair Market Value
of one share of Common Stock upon such vesting dates (subject to any applicable
maximum value) shall be paid with respect to such Phantom Stock unit granted to
the Participant. Payment may be made, at the discretion of the Committee, in
cash or in shares of Common Stock valued at their Fair Market Value on the
applicable vesting dates, or in a combination thereof.

<PAGE>   11


                            11. DIVIDEND EQUIVALENTS

11.1. GRANT OF DIVIDEND EQUIVALENTS. A Dividend Equivalent granted to a
Participant is an Award in the form of a right to receive cash payments
determined by reference to dividends declared on the Common Stock from time to
time during the term of the Award, which shall not exceed 10 years from the Date
of Grant. Dividend Equivalents may be granted on a stand-alone basis or in
tandem with other Awards. Dividend Equivalents granted on a tandem basis shall
expire at the time the underlying Award is exercised or otherwise becomes
payable to the Participant, or expires.

11.2. PAYMENT OF DIVIDEND EQUIVALENTS. Dividend Equivalent Awards shall be
payable in cash or in shares of Common Stock, valued at their Fair Market Value
on either the date the related dividends are declared or the date the Dividend
Equivalents are paid to a Participant, as determined by the Committee. Dividend
Equivalents shall be payable to a Participant as soon as administratively
practicable following the time dividends are declared and paid with respect to
the Common Stock, or at such later date as the Committee shall specify in the
Award Agreement.

                              12. CHANGE IN CONTROL

12.1. EFFECT OF CHANGE IN CONTROL. The Committee may, in an Award Agreement,
provide for the effect of a Change in Control on an Award. Such provisions may
include any one or more of the following: (a) the acceleration, limitation or
extension of time periods for purposes of exercising, vesting in, or realizing
gain from any Award; (b) the waiver or modification of performance or other
conditions related to the payment or other rights under an Award; (c) provision
for the cash settlement of an Award for an equivalent cash value, as determined
by the Committee; or (d) such other modification or adjustment to an Award as
the Committee deems appropriate to maintain and protect the rights and interests
of Participants upon or following a Change in Control.

12.2. DEFINITION OF CHANGE IN CONTROL. For purposes hereof, a "Change in
Control" shall be deemed to have occurred upon:

         (a) an acquisition subsequent to the Effective Date by any individual,
entity or group (within the meaning of section 13(d)(3) or 14(d)(2) of the
Exchange Act) (a "Person") of beneficial ownership (within the meaning of Rule
13d-3 promulgated under the Exchange Act) of thirty percent (30%) or more of
either (i) the then outstanding shares of Common Stock or (ii) the combined
voting power of the then outstanding Corporation Voting Securities; excluding,
however, the following: (A) any acquisition directly from the Corporation, other
than an acquisition by virtue of the exercise of a conversion privilege unless
the security being so converted was itself acquired directly from the
Corporation, (B) any acquisition by the Corporation and (C) any acquisition by
an employee benefit plan (or related trust) sponsored or maintained by the
Corporation or any Subsidiary;



                                       11
<PAGE>   12


         (b) during any period of two (2) consecutive years (not including any
period prior to the Effective Date), individuals who at the beginning of such
period constitute the Board (and any new directors whose election by the Board
or nomination for election by the Corporation's shareholders was approved by a
vote of at least two-thirds (2/3) of the directors then still in office who
either were directors at the beginning of the period or whose election or
nomination for election was so approved) cease for any reason (except for death,
disability or voluntary retirement) to constitute a majority thereof;

         (c) the approval by the shareholders of the Corporation of a merger,
consolidation, reorganization or similar corporate transaction, whether or not
the Corporation is the surviving corporation in such transaction, other than a
merger, consolidation, reorganization or similar corporate transaction that
would result in the Corporation Voting Securities outstanding immediately prior
thereto continuing to represent (either by remaining outstanding or by being
converted into voting securities of the surviving entity) at least fifty percent
(50%) of the combined voting power of the Corporation Voting Securities (or the
voting securities of such surviving entity) outstanding immediately after such
merger, consolidation, reorganization or similar corporate transaction;

         (d) the approval by the shareholders of the Corporation of (i) the sale
or other disposition of all or substantially all of the assets of the
Corporation, or (ii) a complete liquidation or dissolution of the Corporation;
or

         (e) adoption by the Board of a resolution to the effect that any Person
has acquired effective control of the business and affairs of the Corporation.

Notwithstanding the foregoing, if, at the time of a change described in clause
(i) or (ii) below, Duke and Phillips (or any successor to Duke and/or Phillips)
own, directly or indirectly and on an aggregate basis, at least fifty percent
(50%) of the combined voting power of the then outstanding Corporate Voting
Securities, a Change in Control shall not include (i) any change in the
ownership or ownership structure of Duke or Phillips and (ii) any change in the
percentage ownership interests held by Duke and/or Phillips in the Corporation.

                              13. AWARD AGREEMENTS

13.1. FORM OF AGREEMENT. Each Award under this Plan shall be evidenced by an
Award Agreement in a form approved by the Committee setting forth the number of
shares of Common Stock, units or other rights (as applicable) subject to the
Award, the exercise, base or purchase price (if any) of the Award, the time or
times at which an Award will become vested, exercisable or payable, the duration
of the Award and, in the case of Performance Awards, the applicable performance
criteria and goals. The Award Agreement shall also set forth other material
terms and conditions applicable to the Award as determined by the Committee
consistent with the limitations of this Plan. Award Agreements evidencing
Incentive Stock Options shall contain such terms and



                                       12
<PAGE>   13


conditions as may be necessary to meet the applicable provisions of section 422
of the Code.

13.2. TERMINATION OF SERVICE. The Award Agreements may include provisions
describing the treatment of an Award in the event of the retirement, disability,
death or other termination of a Participant's employment with or other service
to the Corporation and all Subsidiaries, such as provisions relating to the
vesting, exercisability, acceleration, forfeiture or cancellation of the Award
in these circumstances, including any such provisions as may be appropriate for
Incentive Stock Options as described in Section 6.6(b) hereof.

13.3. FORFEITURE EVENTS. The Committee may specify in an Award Agreement that
the Participant's rights, payments and benefits with respect to an Award shall
be subject to reduction, cancellation, forfeiture or recoupment upon the
occurrence of certain specified events, in addition to any otherwise applicable
vesting or performance conditions of an Award. Such events shall include, but
shall not be limited to, termination of employment for cause, violation of
material Corporation or Subsidiary policies, breach of noncompetition,
confidentiality or other restrictive covenants that may apply to the
Participant, or other conduct by the Participant that is detrimental to the
business or reputation of the Corporation or any Subsidiary.

13.4. CONTRACT RIGHTS; AMENDMENT. Any obligation of the Corporation to any
Participant with respect to an Award shall be based solely upon contractual
obligations created by an Award Agreement. No Award shall be enforceable until
the Award Agreement has been signed on behalf of the Corporation by its
authorized representative and signed by the Participant and returned to the
Corporation. By executing the Award Agreement, a Participant shall be deemed to
have accepted and consented to the terms of such Award Agreement and this Plan,
and any action taken in good faith under this Plan by and within the discretion
of the Committee, the Board or their delegates. Award Agreements covering
outstanding Awards may be amended or modified by the Committee in any manner
that may be permitted for the grant of Awards under the Plan, subject to the
consent of the Participant to the extent provided in the Award Agreement.

                             14. GENERAL PROVISIONS

14.1. NO ASSIGNMENT OR TRANSFER; BENEFICIARIES. Except as provided in Sections
6.5 and 8.3 hereof, Awards under the Plan shall not be assignable or
transferable, except by will or by the laws of descent and distribution, and
during the lifetime of a Participant the Award shall be exercised only by such
Participant or by his guardian or legal representative. Notwithstanding the
foregoing, the Committee may provide in the terms of an Award Agreement that the
Participant shall have the right to designate a beneficiary or beneficiaries who
shall be entitled to any rights, payments or other interests specified under an
Award following the Participant's death.

14.2. DEFERRALS OF PAYMENT. The Committee may permit a Participant to defer the
receipt of payment of cash or delivery of shares of Common Stock that would
otherwise



                                       13
<PAGE>   14


be due to the Participant by virtue of the exercise of a right or the
satisfaction of vesting or other conditions with respect to an Award. If any
such deferral is to be permitted by the Committee, the Committee shall establish
the rules and procedures relating to such deferral, including, without
limitation, the period of time in advance of payment when an election to defer
may be made, the time period of the deferral and the events that would result in
payment of the deferred amount, the interest or other earnings attributable to
the deferral and the method of funding, if any, attributable to the deferred
amount.

14.3. RIGHTS AS SHAREHOLDER. A Participant shall have no rights as a holder of
Common Stock with respect to any unissued securities covered by an Award until
the date the Participant becomes the holder of record of these securities.
Except as provided in Section 3.2 hereof, no adjustment or other provision shall
be made for dividends or other shareholder rights, except to the extent that the
Award Agreement provides for Dividend Equivalents, dividend payments or similar
economic benefits.

14.4. EMPLOYMENT OR SERVICE. Nothing in the Plan, in the grant of any Award or
in any Award Agreement shall confer upon any Eligible Person the right to
continue in the capacity in which he is employed by or otherwise serves the
Corporation or any Subsidiary.

14.5 TRANSFER OF EMPLOYMENT TO DUKE. For purposes of the Plan and all Award
Agreements governing outstanding Awards held by a Participant as of the date, if
any, of such Participant's transfer of employment as hereinafter described,
unless provided otherwise by the Committee in an Award Agreement, a Participant
who is an Employee shall not be considered to have terminated employment with
the Corporation and all Subsidiaries if such Participant's employment is
transferred directly from the Corporation or any Subsidiary to Duke (or an
entity that is wholly owned, directly or indirectly, by Duke) at a time when
Duke owns, directly or indirectly, greater than fifty percent (50%) of the
combined voting power of the then outstanding Corporation Voting Securities;
provided, however, that such a Participant shall be considered to have
thereafter terminated such employment upon the first to occur of (a) the date
such Participant terminates employment with the Corporation, all Subsidiaries,
Duke and all entities that are wholly owned, directly or indirectly, by Duke and
(b) the date Duke ceases to own, directly or indirectly, greater than fifty
percent (50%) of the combined voting power of the then outstanding Corporation
Voting Securities. The provisions of this Section 14.5 shall cease to apply as
of the first date upon which Duke owns, directly or indirectly, fifty percent
(50%) or less of the combined voting power of the then outstanding Corporation
Voting Securities.

14.6. SECURITIES LAWS. No shares of Common Stock will be issued or transferred
pursuant to an Award unless and until all then applicable requirements imposed
by federal and state securities and other laws, rules and regulations and by any
regulatory agencies having jurisdiction, and by any stock exchanges upon which
the Common Stock may be listed, have been fully met. As a condition precedent to
the issuance of shares pursuant to the grant or exercise of an Award, the
Corporation may require the Participant to take any reasonable action to meet
such requirements. The Committee may



                                       14
<PAGE>   15


impose such conditions on any shares of Common Stock issuable under the Plan as
it may deem advisable, including, without limitation, restrictions under the
Securities Act of 1933, as amended, under the requirements of any stock exchange
upon which such shares of the same class are then listed, and under any blue sky
or other securities laws applicable to such shares.

14.7. TAX WITHHOLDING. The Participant shall be responsible for payment of any
taxes or similar charges required by law to be withheld from an Award or an
amount paid in satisfaction of an Award, which shall be paid by the Participant
on or prior to the payment or other event that results in taxable income in
respect of an Award. The Award Agreement shall specify the manner in which the
withholding obligation shall be satisfied with respect to the particular type of
Award.

14.8. UNFUNDED PLAN. The adoption of this Plan and any setting aside of cash
amounts or shares of Common Stock by the Corporation with which to discharge its
obligations hereunder shall not be deemed to create a trust or other funded
arrangement. The benefits provided under this Plan shall be a general, unsecured
obligation of the Corporation payable solely from the general assets of the
Corporation, and neither a Participant nor the Participant's permitted
transferees or estate shall have any interest in any assets of the Corporation
or any Subsidiary by virtue of this Plan, except as a general unsecured creditor
of the Corporation. Notwithstanding the foregoing, the Corporation shall have
the right to implement or set aside funds in a grantor trust subject to the
claims of the Corporation's creditors to discharge its obligations under the
Plan.

14.9. OTHER COMPENSATION AND BENEFIT PLANS. The adoption of the Plan shall not
affect any other stock incentive or other compensation plans in effect for the
Corporation or any Subsidiary, nor shall the Plan preclude the Corporation from
establishing any other forms of stock incentive or other compensation for
employees of the Corporation or any Subsidiary. The amount of any compensation
deemed to be received by a Participant pursuant to an Award shall not constitute
compensation with respect to which any other employee benefits of such
Participant are determined, including, without limitation, benefits under any
bonus, pension, profit sharing, life insurance or salary continuation plan,
except as otherwise specifically provided by the terms of such plan.

14.10. PLAN BINDING ON SUCCESSORS. The Plan shall be binding upon the
Corporation, its successors and assigns, and the Participant, his executor,
administrator and permitted transferees and beneficiaries.

14.11. CONSTRUCTION AND INTERPRETATION. Whenever used herein, nouns in the
singular shall include the plural, and the masculine pronoun shall include the
feminine gender. Headings of Articles and Sections hereof are inserted for
convenience and reference and constitute no part of the Plan.

14.12. SEVERABILITY. If any provision of the Plan or any Award Agreement shall
be determined to be illegal or unenforceable by any court of law in any
jurisdiction, the



                                       15
<PAGE>   16


remaining provisions hereof and thereof shall be severable and enforceable in
accordance with their terms, and all provisions shall remain enforceable in any
other jurisdiction.

14.13. GOVERNING LAW. The validity and construction of this Plan and of the
Award Agreements shall be governed by the laws of the State of Delaware.

                  15. EFFECTIVE DATE, TERMINATION AND AMENDMENT

15.1. EFFECTIVE DATE; SHAREHOLDER APPROVAL. The Effective Date of the Plan shall
be the date of the adoption of the Plan by the Board, provided the Plan is
approved by the shareholders of the Corporation on such date or within 12 months
thereafter.

15.2. TERMINATION. The Plan shall terminate on the date immediately preceding
the tenth anniversary of the date the Plan is adopted by the Board. The Board
may, in its sole discretion and at any earlier date, terminate the Plan.
Notwithstanding the foregoing, no termination of the Plan shall in any manner
affect any Award theretofore granted without the consent of the Participant or
the permitted transferee of the Award.

15.3. AMENDMENT. The Board may at any time and from time to time and in any
respect, amend or modify the Plan; provided, however, that no amendment or
modification of the Plan shall be effective without the consent of the
Corporation's shareholders that would (a) change the class of Eligible Persons
under the Plan, or (b) increase the number of shares of Common Stock reserved
for issuance under the Plan or for certain types of Awards under Section 3.1
hereof. In addition, the Board may seek the approval of any amendment or
modification by the Corporation's shareholders to the extent it deems necessary
or advisable in its sole discretion for purposes of compliance with section 422
of the Code, the listing requirements of the New York Stock Exchange or for any
other purpose. No amendment or modification of the Plan shall in any manner
affect any Award theretofore granted without the consent of the Participant or
the permitted transferee of the Award.
