    DUKE ENERGY AND PHILLIPS PETROLEUM ANNOUNCE DEFINITIVE AGREEMENT FORMING
                  PREMIER GAS GATHERING AND PROCESSING COMPANY
   -- DUKE ENERGY AND PHILLIPS PETROLEUM EACH TO RECEIVE $1.2 BILLION IN CASH;
                          IPO PLANNED FOR NEW COMPANY -

CHARLOTTE, N.C. - Duke Energy (NYSE: DUK) and Phillips Petroleum (NYSE: P) today
announced that they have signed definitive agreements to combine Duke Energy's
gas gathering and processing businesses and Phillips Petroleum's Gas Processing
and Marketing (GPM) unit to form a new midstream company to be called Duke
Energy Field Services (DEFS). This new company will become the nation's largest
midstream natural gas liquids business and the premier gatherer and processor of
natural gas in the continental United States, with an expected enterprise value
of between $5 billion and $6 billion. The definitive agreements have been
unanimously approved by both companies' boards of directors. Due diligence has
been completed. The transaction is expected to close by first quarter 2000,
subject to regulatory approval.

Under the terms of the agreement, the new company will seek to arrange $2.4
billion of debt financing and, upon closing of the transaction, will make
one-time cash distributions of $1.2 billion to both Duke Energy and Phillips
Petroleum. In addition, the existing NGL arrangements between Phillips Petroleum
and GPM will be maintained by the new company for an initial term of 15 years.
At closing, Duke Energy will own about 70 percent of the new company, and
Phillips Petroleum will own about 30 percent.

During the first half of 2000, following completion of the transaction and
subject to market conditions, it is expected that the new company will offer
approximately 20 percent of its equity to the public in an initial public
offering. The proceeds of the offering will be used to reduce debt incurred by
the new company in the transaction. DEFS will provide investors the opportunity
to participate directly in the future growth and consolidation of the gas
gathering and processing industry. Given the company's size and access to the
capital markets, it will immediately have the flexibility to pursue its growth
opportunities. The agreements governing DEFS set forth a formula that adjusts
Duke Energy's and Phillips Petroleum's post-IPO equity interests depending on
the public market valuation of the new company. Accordingly, assuming a value
range for the new company between $5 billion and $6 billion, Duke Energy's
post-IPO equity ownership in the new company would range between 55 percent and
57 percent, and Phillips Petroleum's post-IPO ownership would range between 23
percent and 25 percent. Duke Energy expects to consolidate the new company for
financial reporting purposes; Phillips Petroleum expects to account for its
ownership in DEFS on an equity basis.

TRANSACTION ACCRETIVE TO BOTH DUKE ENERGY AND PHILLIPS PETROLEUM

The transaction will be immediately accretive to both Duke Energy and Phillips
Petroleum. The transaction will help move Duke Energy toward the top of its
targeted range for growing earnings per share 8 percent to 10 percent annually.
The $1.2 billion cash payment will reduce the need for Duke Energy to issue
equity to fund its capital expenditure plans. Duke Energy is firmly focused on
becoming the world's premier global energy merchant.

Phillips Petroleum expects to retain approximately $1.15 billion, after taxes,
of the $1.2 billion that it will receive from this transaction. Phillips
Petroleum's proceeds from the transaction will be used initially to reduce debt,
as well as for other corporate purposes. As a result, Phillips Petroleum expects
its net debt-to-capital ratio to decline from 47 percent to approximately 40
percent.
Richard B. Priory, chairman, president and chief executive officer of Duke
Energy, said, "This innovative transaction demonstrates our ability to seize
opportunities for growth and value creation. This transaction

is the most recent and vivid example of Duke Energy's global energy merchant
strategy. As the energy industry changes, there will be opportunities for those
companies with the expertise, financial strength and assets to act quickly,
decisively and creatively.

"All of our energy businesses are top tier performers. By combining the assets
and people of Duke Energy's gas gathering and processing business with GPM, we
are building a new market leader. And, with the prospect of an IPO, we'll tap
new financing and ownership opportunities that will unlock the full value of the
new company," Priory said.

James J. Mulva, chairman, president and chief executive officer of Phillips
Petroleum, stated, "This transaction is an integral step in achieving our
strategic objectives recently communicated to the financial community. It
monetizes a substantial portion of the value of one of Phillips Petroleum's key
non-E&P assets, thereby increasing Phillips Petroleum's financial flexibility to
pursue attractive exploration and production growth opportunities. It also
enhances and makes more transparent the value of our GPM asset.

"In Duke Energy, we have a company that intends to capture the potential in this
business and has an excellent record as both an operator of assets and a builder
of value. We are also maintaining both financial and operational integration
between Phillips Petroleum and the midstream business. Financially, Phillips
Petroleum will hold a significant ownership position in a publicly held
midstream company, with a strong growth platform of high quality assets,
financial resources and strong management. We believe the new company will have
greater access to capital to grow its business than the GPM unit historically
obtained as part of Phillips Petroleum. Operationally, we have ensured a
continued NGL supply for our downstream businesses," Mulva concluded.

ABOUT THE NEW DUKE ENERGY FIELD SERVICES

The new company will have a strong position in most of the significant
hydrocarbon basins in the continental United States. The combined revenues and
EBITDA for the two businesses in the third quarter of 1999 was $1.6 billion and
$183 million, respectively. The new company will operate 67 plants, 57,000 miles
of pipelines and an estimated 17 TCF of contracted supply. It will process
approximately 5 BCFD of raw gas, and produce 400,000 BPD of NGLs. Duke Energy
and Phillips Petroleum believe that the new company will realize synergies,
primarily from operating efficiencies. James W. Mogg, currently president of
Duke Energy's gathering and processing business (also called Duke Energy Field
Services), will become chairman, president, and chief executive officer of the
new company. Michael Panatier, currently president and chief executive of GPM,
will become vice chairman. "This combination represents the latest and most
dramatic example of the restructuring and consolidation in the midstream gas
business. It immediately creates shareholder value for both Duke Energy and
Phillips Petroleum. By combining DEFS' and GPM's businesses, we will have the
best collection of people and assets in the gathering and processing industry.
This transaction brings together the fastest growing midstream business, DEFS,
with one of the most experienced, GPM. Additionally, GPM's assets and gas
contracts provide additional balance to our existing business," said Mogg.

The new company will be governed by a board of directors that will initially
consist of three directors to be chosen by Duke Energy and two directors to be
selected by Phillips Petroleum. Priory and Mulva have agreed to serve on the
DEFS board. Following the IPO, the board will be expanded from five to 11; Duke
Energy will choose seven members (two of whom will be independent) and Phillips
Petroleum will choose four (one of whom will be independent). DEFS will be
headquartered in Denver, Colo.

Duke Energy's existing midstream business is the largest U.S. producer of NGLs,
one of the largest natural gas gatherers and marketers and one of the largest
NGL marketers. In 1999, DEFS became the industry's top NGL producer by acquiring
UPR's natural gas gathering, processing, fractionation and NGL pipelines for
$1.35 billion. The company operates 52 plants today in Wyoming, Colorado,
Kansas, Oklahoma, New Mexico, Texas, along the Gulf Coast and in northwestern
Alberta, Canada.

Phillips Petroleum's NGL business, GPM, has operated Phillips Petroleum's gas
gathering and processing units in the continental United States since 1992. GPM
operates 15 plants in Texas, New Mexico and Oklahoma.

The NGL industry provides processing of natural gas and fractionation of natural
gas liquids to produce liquid products such as ethane, propane, butanes and
natural gasolines. Customers of the NGL business include gas and crude
producers, refineries, petrochemical plants and propane distributors. Morgan
Stanley Dean Witter acted as financial advisor to Duke Energy and Merrill Lynch
& Co. acted as financial advisor to Phillips Petroleum.

OTHER BOARD ACTION

Duke Energy's board of directors approved the definitive agreement at their
meeting in Charlotte today. The company also announced plans to book a material
reserve in the fourth quarter for contingencies resulting from the construction
activity on Duke Power's electric generating plants in the 1970s and 1980s. The
reserve is expected to be more than $750 million. Reserves for similar
contingencies have been accrued in lesser amounts as appropriate throughout the
1990s.
