       $35 BILLION STRATEGIC COMBINATION CREATES THIRD-LARGEST INTEGRATED
                               U.S. ENERGY COMPANY

                    ARCHIE W. DUNHAM TO SERVE AS CHAIRMAN AND
       JAMES J. MULVA TO SERVE AS PRESIDENT AND CHIEF EXECUTIVE OFFICER OF
                                 CONOCOPHILLIPS

Houston, Texas, and Bartlesville, Oklahoma (Nov.18, 2001) --- Conoco Inc.
(NYSE:COC) and Phillips Petroleum Company (NYSE:P) today announced that their
boards of directors have unanimously approved a merger of equals, and that the
companies have signed a definitive merger agreement. The new company, which will
be named ConocoPhillips, will be a strong competitor with enhanced returns and
accelerated growth opportunities from an excellent financial and operational
position.

ConocoPhillips will be the third-largest integrated U.S. energy company based
on market capitalization and oil and gas reserves and production. Worldwide,
it will be the sixth-largest energy company based on hydrocarbon reserves and
the fifth-largest global refiner.

As a premier global major, ConocoPhillips will have the size, portfolio of
high-quality assets, and the capabilities and financial strength to generate
enhanced value for its shareholders. Specifically, ConocoPhillips will have:

        o     substantial growth opportunities;
        o     world-class technology, workforce and operational practices;
        o     significant opportunity to enhance its exploration portfolio;
        o     diversified earnings and cash flow;
        o     a strong balance sheet, with an expected debt-to-capitalization
              ratio of approximately 35 percent;
        o     improved capital efficiency; and
        o     an efficient cost structure.

Under the terms of the agreement, Phillips shareholders will receive one
share of new ConocoPhillips common stock for each share of Phillips they own
and Conoco shareholders will receive 0.4677 shares of new ConocoPhillips
common stock for each share of Conoco they own. Based on the closing market
prices for the shares of both companies on Friday, Nov. 16, 2001, and their
debt levels as of Sept. 30, 2001, the new company would have an enterprise
value of $53.5 billion ($34.9 billion of equity;$18.6 billion of debt and
preferred securities). At inception, Phillips shareholders will own about
56.6 percent and Conoco shareholders will own about 43.4 percent of the new
company. The transaction is structured to be tax-free to the shareholders of
each company.

                                      -2-

The transaction is expected to be accretive to earnings and cash flow per
share of each company after achieving anticipated annual cost savings of
approximately $750 million. The companies expect to achieve the annual rate of
synergies within the first year after closing.

Upon completion of the merger, Archie W. Dunham, Conoco chairman and chief
executive officer, will serve as chairman of ConocoPhillips and will delay
his scheduled retirement to 2004. James J. Mulva, Phillips chairman and chief
executive officer, will be president and chief executive officer of the
combined company, and also become chairman upon Mr. Dunham's retirement. The
ConocoPhillips board of directors will consist of 16 directors, eight
designated by each of the two companies, including Mr. Dunham and Mr. Mulva.
ConocoPhillips will be headquartered in Houston, with a significant and
continuing presence in Bartlesville and Oklahoma.

Mr. Dunham of Conoco said, "This merger of equals represents an excellent
strategic fit for both Conoco and Phillips. It will position ConocoPhillips
as a stronger U.S.-based, global energy producer by significantly enhancing
its capability and growth prospects on five continents in both current and
prospective ventures, while generating major synergies. It will create
significant long-term value for the shareholders of both companies, partly
through cost savings, but also because of a significantly larger portfolio of
global assets, skills and opportunities. With a very strong balance sheet,
more capital for upstream investment, and greater operational efficiency
downstream, ConocoPhillips will be a tough new competitor to the larger
global majors."

Mr. Mulva of Phillips said, "This merger ensures that the United States will
be home to a third major international petroleum company. For Conoco and
Phillips, joining forces is the ideal way to be competitive in the reshaped
energy industry. ConocoPhillips will move forward to deliver on our legacy
growth projects, develop new opportunities in existing and emerging business
lines, and enhance returns in our downstream business with our companies'
leading technologies. With our greater financial strength and flexibility, we
will be able to fund these capital programs while also reducing our
debt-to-capitalization ratio, repurchasing shares and providing a competitive
dividend. Just as important, our compatible cultures, similar values and
determined focus will facilitate a smooth integration and enable
ConocoPhillips to get off to a fast and successful start."

Mr. Mulva added, "I want to emphasize that, reflecting our companies' deep
roots in Oklahoma, ConocoPhillips will continue to have a significant
operational presence here. ConocoPhillips intends to continue the
philanthropic and community commitments of Conoco and Phillips. In addition,
ConocoPhillips will initiate technology or other partnership commitments with
the University of Oklahoma and Oklahoma State University."

SUPERIOR GROWTH AND STRONG CORE CAPABILITIES

In the upstream segment, ConocoPhillips' global scale and presence will allow
for increased efficiency in core areas and delivery of legacy growth
projects. The combined company will have pro forma year 2000 hydrocarbon
reserves of 8.7 billion barrels of oil equivalent (BOE) and daily production
of 1.7 million BOE, based on the companies' estimates for 2001 year-end
production. ConocoPhillips will have numerous legacy asset positions,
including those in Alaska, Canada, the Lower 48, the North Sea, Venezuela,
China, the Timor Sea, Indonesia, Vietnam, the Middle East, Russia and the
Caspian area.

In the refining and marketing segment, ConocoPhillips will operate or have
equity interests in 19 refineries in the United States, the U.K., Ireland,
Germany, the Czech Republic and Malaysia, with a refining capacity of 2.6
million barrels a day. It will also have a strong marketing presence in the
United States.

In addition, ConocoPhillips will continue Phillips' equity participation in
the natural gas gathering and processing joint venture, Duke Energy Field
Service, and in the chemicals and plastics joint venture, Chevron Phillips
Chemicals.

SUBSTANTIAL RETURN ENHANCEMENTS AND VALUE CREATION

The companies expect the combined enterprise to achieve annual cost savings of
at least $750 million within the first full year after closing. These savings
will result from more efficient exploration, production and downstream
activities, and the elimination of duplicate corporate and administrative
positions, programs and operating offices. A transition team led by Philip L.
Frederickson, Conoco's Senior Vice President Corporate Strategy and Business
Development, and John E. Lowe, Phillips' Senior Vice President, Corporate
Strategy and Development, will begin work immediately to ensure integration
occurs quickly and smoothly.

It is anticipated that upon closing of the transaction, the ConocoPhillips
board of directors will adopt a competitive dividend policy. Currently,
Conoco pays an annual dividend of $0.76 per share and Phillips pays an annual
dividend of $1.44 per share.

The merger is conditioned upon, among other things, the approvals of the
shareholders of each company and customary regulatory approvals. The
transaction is expected to be completed in the second half of 2002.
