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,


                                                     CARL C. ICAHN
