VIA FEDERAL EXPRESS AND FACSIMILE 
----------------------------------
Mr. Luke R. Corbett
Chairman and Chief Executive Officer
Kerr-McGee Corporation
123 Robert S. Kerr Avenue
Oklahoma City, Oklahoma 73102

Dear Mr. Corbett:

      As we have previously discussed with you, each of us is a large
shareholder of Kerr-McGee Corporation ("KMG"), beneficially owning, in the
aggregate, approximately 11.6 million shares or approximately 7.6% of the
outstanding shares of KMG's common stock. Entities affiliated with Carl Icahn
recently proposed Carl Icahn and Barry Rosenstein, managing partner of Jana
Partners (a $3 billion hedge fund), as nominees for KMG's board of directors at
the upcoming annual meeting. This action was taken in order to help ensure that
KMG is focused on maximizing shareholder value. While management's recent
announcement of its intention to review strategic alternatives for its chemicals
business is a positive first step, we feel this action does not go far enough
toward maximizing the value of KMG's common stock.

      A great opportunity exists today for shareholders of KMG. Never before has
there been such a disconnect between the stock market valuation of publicly
traded E&P companies such as KMG on a per barrel of oil equivalent ("boe") of
proved reserves basis and the value at which oil and gas futures are trading in
the commodity markets. We believe that this spread can be captured by KMG by
selling today a portion of its production for delivery over the next five years
and utilizing the proceeds from such a sale, today, to immediately repurchase
stock. We believe that if KMG were to follow the plan outlined below (and
detailed in the attached schedule), KMG's share price would increase
significantly. The plan would require KMG to take the following steps:

1.    Sell the chemical business;

2.    Enter into a transaction to monetize forward production and capitalize on
      today's high price of oil and gas, low interest rate environment and
      increased commodity market liquidity; and

3.    Utilize the proceeds from the chemical business sale and the forward sale
      of a





      portion of KMG's future oil and gas production to buy back shares.

      At KMG's current market price of $78.99 per share (as of the close of the
market on March 2, 2005), and pro-forma for the sale of its chemicals business
for $1.7 billion (the mid-point of the range projected on KMG's January 26, 2005
fourth quarter conference call), KMG is trading at approximately $11.80 per boe
of proved in the ground reserves. To monetize the current discount in KMG's
stock market valuation versus the commodity market valuation for oil and gas, we
recommend that KMG immediately execute a Volumetric Production Payment
transaction ("VPP") for 50 million boe's of proved producing reserves per year
over each of the next five years (i.e., 250 million boe's of production total,
or approximately 32% of KMG's total proved producing reserves), constituting
approximately 37% of KMG's projected 2005 production.

      Based on the current forward curve for oil and gas, the low interest rate
environment and increased liquidity in the commodity markets, we believe (as a
result of discussions with commodity trading firms) that KMG could realize
proceeds of between $35 and $38 per boe sold forward through a VPP transaction.
As such, KMG could raise a total of approximately $8.75 BILLION OF CASH
(assuming the VPP transaction at $35 per boe), or approximately 60% of its
enterprise value (excluding KMG's chemicals business), by selling only
approximately 21% of its total proved reserves. After raising the proceeds
described above (including proceeds from the sale of the chemicals business),
KMG should repurchase up to approximately 116 million shares of its stock at $90
per share. Following such a transaction, KMG would still have approximately 950
million boe of proved reserves, approximately 56% of which would be proved
developed reserves and approximately 44% would be proved undeveloped reserves.

      Assuming that KMG would trade at its current value of $11.80 per boe of
proved reserves (excluding the chemical business), the pro forma share price
following the proposed transactions would be $111 per share. Historically, we
believe investors have penalized KMG's share price due to what we perceive as
poor results achieved in exploration, drilling and use of free cash flow.
However, after giving effect to the proposed VPP transaction and the sale of the
chemicals business, we believe that the public market valuation for KMG's
remaining reserves could increase to be more in line with the reserve valuations
attributed to its comparable companies (see attached schedule). If this were to
occur, KMG could trade at $132 per share. Obviously, there can be no assurance
that KMG common stock will trade within the $111 to $132 range, even if all of
these transactions are undertaken and completed.

      We would like to discuss this recommendation with you at your earliest
convenience since we feel it is important to move quickly while the opportunity
exists.

                                Very truly yours,
