          CONOCO TO COMBINE ITS CLASS A AND CLASS B SHARES INTO A NEW,
                          SINGLE CLASS OF COMMON STOCK

         HOUSTON (July 17, 2001) -- Conoco Inc. (NYSE: COC.A) (NYSE COC.B) today
announced that its Board of Directors has approved, and recommended to the
stockholders for approval, the elimination of Conoco's dual class capital
structure by combining the company's Class A common stock and Class B common
stock into a single class of new common stock on a one-for-one basis.

         The transaction is subject to the approval of Conoco Class A
stockholders and Class B stockholders voting together as a single class, and to
the approval of the Class B stockholders voting as a separate class. The current
dual class structure was established in connection with Conoco's 1998 initial
public offering (IPO) of Class A common stock. At the time of the IPO, Conoco's
former sole stockholder, E.I. du Pont de Nemours and Company, retained ownership
of all of the Class B common stock, representing approximately 92 percent of the
voting power and 70 percent of all outstanding Conoco stock. Such Class B common
stock was subsequently distributed to the DuPont stockholders.

         DuPont received a ruling from the Internal Revenue Service that the
distribution would be tax free to DuPont and its stockholders. DuPont recently
received a supplemental ruling from the Internal Revenue Service confirming that
the proposed combination will not affect the prior letter ruling.

confusion that resulted from the dual class structure, and will end trading
disparities that existed between the Class A and Class B stock," said Conoco
Chairman and CEO Archie Dunham. "This also is expected to increase the overall
liquidity of Conoco's common stock."

         After the transaction, the holders of the new common stock will have
one vote per share on all matters submitted to a stockholder vote. Class B
stockholders currently have five votes per share.

         Conoco intends to call a special meeting as soon as practicable to
obtain the approval of its stockholders. A complete description of the proposal
will be included in the proxy statement for the special meeting, and
stockholders are encouraged to read the proxy statement before making any
decision with respect to the proposal.

         Conoco is a major, integrated energy company headquartered in Houston
and active in more than 40 countries.
