BACKGROUND

            On February 10, 2005, representatives of the Icahn Parties and the
JANA Parties had a meeting in which they discussed Kerr-McGee. The parties also
discussed the possibility of JANA Master selling to the Icahn Parties an option
to purchase shares of Common Stock.

            On February 14, 2005, the Icahn Parties acquired, for $1,500,000, an
option (the "JANA Option") to purchase, in the aggregate, 250,000 shares of
Common Stock of Kerr-McGee from JANA Master. Pursuant to the exercise of the
JANA Option on March 1, 2005, Icahn Partners purchased 96,000 shares of Common
Stock, Icahn Master purchased 104,000 shares of Common Stock and High River
purchased 50,000 shares of Common Stock. The JANA Option had an exercise price
of $60.00 per share and an expiration date of August 14, 2005.

            On or about February 23, 2004, Carl C. Icahn and Barry S. Rosenstein
spoke with Luke R. Corbett, Chairman and Chief Executive Officer of Kerr-McGee,
and suggested various actions to be taken by Kerr-McGee that they believe would
enhance stockholder value.

            On March 2, 2005, the Icahn Parties delivered a letter to
Kerr-McGee, notifying Kerr-McGee that the Icahn Parties intend to appear at the
Annual Meeting, in person or by proxy, to nominate and seek to elect Carl C.
Icahn and Barry S. Rosenstein as members of the board of directors of
Kerr-McGee.

            On March 3, 2005, Carl C. Icahn and Barry S. Rosenstein sent a
letter to Kerr-McGee, proposing that Kerr-McGee (i) sell its chemical business,
(ii) enter into a transaction to monetize forward production of a portion of its
reserves and (iii) utilize the proceeds to buy back shares of its stock.

            On March 10, 2005, Carl C. Icahn and Barry S. Rosenstein sent a
letter to Kerr-McGee, responding to Kerr-McGee's March 8, 2005 announcement
regarding the proposed sale of its chemicals business and share repurchase
program.

            On March 10, 2005, Kerr-McGee filed a lawsuit in federal court in
Oklahoma against the Icahn Parties, the JANA Parties and certain of their
respective affiliates, claiming: (i) that the Icahn Parties and the JANA Parties
have violated their disclosure obligations under Section 13(d) of the Exchange
Act, including by filing misleading Schedules 13D which falsely disclaim that
they are acting with each other as a group, and mischaracterize their purpose in
acquiring shares; (ii) that the March 2, 2005 letter in which the Icahn Parties
notified Kerr-McGee of their intention to seek to elect Carl C. Icahn and Barry
S. Rosenstein to the board of directors fails to comply with Kerr-McGee's
bylaws; and (iii) that the Icahn Parties and the JANA Parties have


                                       9

violated Section 14(a) of the Exchange Act and Rule 14a-9 thereunder by filing
false and misleading proxy solicitation materials. The lawsuit requests that the
court enter a judgment: (i) declaring the March 2, 2005 letter from the Icahn
Parties invalid; (ii) ordering the Icahn Parties and the JANA Parties to file
accurate disclosures in accordance with the requirements of Sections 13(d) and
14(a) of the Exchange Act and the regulations promulgated thereunder; (iii)
enjoining the Icahn Parties and the JANA Parties from voting any shares acquired
prior to the filing of true and accurate Schedules 13D; (iv) ordering the Icahn
Parties and the JANA Parties to return any proxies received prior to the filing
of true and accurate disclosures under Section 14(a) of the Exchange Act and the

of Kerr-McGee --designed to change or affect control of Kerr-McGee until 30 days
following the filing of such true and accurate disclosures pursuant to Sections
13(d) and 14(a) of the Exchange Act; and (vi) granting such other and further
relief as the court may deem just and proper.

demanding, pursuant to Delaware law, the right as stockholders to inspect
certain documents and records of Kerr-McGee (including stockholder list
materials).

Parties have from time to time had conversations and met with Luke R. Corbett,
the Chairman and Chief Executive Officer of Kerr-McGee, as well as other
representatives of Kerr-McGee, and have discussed, among other things, the March
3, 2005 and March 10, 2005 letters from Carl C. Icahn and Barry S. Rosenstein
and Kerr-McGee's reaction to the transactions proposed therein.

OTHER PROPOSALS

            The Participants and their affiliates know of no other business to
be presented at the 2005 Annual Meeting. If any other matters should properly
come before the Annual Meeting, it is intended that the persons named on the
enclosed GOLD proxy card will vote that proxy on such other matters in
accordance with their judgment.

VOTING PROCEDURES

            According to Kerr-McGee's Proxy Statement, the voting procedures are
as set forth below.

            A majority of the shares of the Common Stock of Kerr-McGee, present
in person or represented by proxy, shall constitute a quorum for purposes of the
Annual Meeting. Abstentions and broker non-votes are considered to be shares
present for the purpose of determining whether a quorum exists. A broker
non-vote occurs when a nominee holding shares for a beneficial owner does not
vote on a particular proposal because the nominee does not have discretionary
voting power with respect to that item and has not received voting instructions
from the beneficial owner.

            Directors shall be elected by a plurality of the votes present in
person or represented by proxy at the Annual Meeting and entitled to vote on the
election of directors. Abstentions and broker non-votes are not counted as votes
present for the purpose of electing directors. The proposal to amend the Amended
and Restated Certificate of Incorporation of Kerr-McGee requires the affirmative
vote of a majority of the outstanding shares of Common Stock. Abstentions and
broker non-votes will have the effect of votes against the proposal to amend the
Amended and Restated Certificate of Incorporation of Kerr-McGee. In all matters
other than the


                                       12

election of directors and the amendment of the Amended and Restated Certificate
of Incorporation of Kerr-McGee, the affirmative vote of a majority of shares
present in person or represented by proxy at the Annual Meeting and entitled to
vote on the subject matter shall be the act of the stockholders. With respect to
such matters, broker non-votes are not considered to be shares present in person
or represented by proxy, but abstentions are considered to be shares present in
person or represented by proxy, and, therefore, abstentions will have the effect
of votes against the proposal.

            The New York Stock Exchange has determined that the appointment of
independent auditors is a "routine" item. Therefore, a broker or nominee may
vote shares held by it with respect to that item if no instructions have been
received for it at least 15 days before the Annual Meeting.

            Whether or not you are able to attend the Annual Meeting, you are
urged to complete the enclosed GOLD proxy and return it in the enclosed
self-addressed, prepaid envelope. All valid proxies received prior to the
meeting will be voted. If you specify a choice with respect to any item by
marking the appropriate box on the proxy, the shares will be voted in accordance
with that specification. IF NO SPECIFICATION IS MADE, THE PERSONS NAMED ON THE
ENCLOSED GOLD PROXY CARD WILL VOTE YOUR SHARES FOR CARL C. ICAHN AND BARRY S.
ROSENSTEIN WITH RESPECT TO PROPOSAL 1, AND WILL ABSTAIN FROM VOTING WITH RESPECT
TO THE REMAINING PROPOSALS.

PROXY PROCEDURES

            IN ORDER FOR YOUR VIEWS TO BE REPRESENTED AT THE ANNUAL MEETING,
PLEASE MARK, SIGN, DATE AND RETURN THE ENCLOSED GOLD PROXY CARD IN THE ENCLOSED
POSTAGE-PREPAID ENVELOPE.

            The accompanying GOLD proxy card will be voted at the Annual Meeting
in accordance with your instructions on such card.

REVOCATION OF PROXIES

            Any Stockholder who has mailed a white proxy card to Kerr-McGee may
revoke it before it is voted by mailing a duly executed GOLD proxy card to the
Participants bearing a date LATER than the white proxy card delivered to
Kerr-McGee. Proxies may also be revoked at any time prior to voting by: (i)
delivering to the corporate secretary of Kerr-McGee, a written notice, bearing a
date later than the date of the proxy, stating that the proxy is revoked; (ii)
delivering a duly executed proxy bearing a later date than the proxy delivered
previously; or (iii) attending the Annual Meeting and voting in person.

            Only holders of record as of the close of business on the Record
Date will be entitled to vote. If you were a Stockholder of record on the Record
Date, you will retain your voting rights at the Annual Meeting even if you sell
such shares after the Record Date. Accordingly, it is important that you vote
the shares held by you on the Record Date, or grant a


                                       13

proxy to vote such shares on the GOLD proxy card, even if you sell such shares
after the Record Date.

            IF YOUR SHARES ARE HELD IN THE NAME OF A BROKERAGE FIRM, BANK, BANK
NOMINEE OR OTHER INSTITUTION ON THE RECORD DATE, ONLY IT CAN VOTE SUCH SHARES
AND ONLY UPON RECEIPT OF YOUR SPECIFIC INSTRUCTIONS. ACCORDINGLY, PLEASE CONTACT
THE PERSON RESPONSIBLE FOR YOUR ACCOUNT AND INSTRUCT THAT PERSON TO EXECUTE ON
YOUR BEHALF THE GOLD PROXY CARD AS SOON AS POSSIBLE.

COST AND METHOD OF SOLICITATION

            Solicitation of proxies shall be made by Messrs. Icahn, Meister,
Intrieri, Rosenstein and Roth.

            The Icahn Parties and the JANA Parties have retained D.F. King &
Co., Inc. ("King") to conduct the solicitation, for which King is to receive a
fee of approximately $200,000, plus a fee per call and reimbursement for its
reasonable out-of-pocket expenses. The Icahn Parties and the JANA Parties have
agreed to indemnify King against certain liabilities and expenses, including
certain liabilities under the federal securities laws. Insofar as
indemnification for liabilities arising under the federal securities laws may
be permitted to King pursuant to the foregoing provisions, we have been
informed that in the opinion of the Securities and Exchange Commission, such
indemnification is against public policy and is therefore unenforceable.
Proxies may be solicited by mail, courier services, Internet, advertising,
telephone or telecopier or in person. It is anticipated that King will employ
approximately 100 persons to solicit proxies from Stockholders for the Annual
Meeting. The total expenditures in furtherance of, or in connection with, the
solicitation of proxies is $[_________] to date, and is estimated to
be $[________] in total.             

                  The Icahn Parties and the JANA Parties agreed on March 24,
2005 to each pay half of all costs related to the solicitation of proxies
(including expenditures for public relations and financial advisers, proxy
solicitors, advertising, printing, transportation and related expenses), except
that the Icahn Parties and the JANA Parties will each bear their own legal
expenses. The Icahn Parties and the JANA Parties intend to seek reimbursement
for the costs and expenses associated with the proxy solicitation in the event
that the Nominees are elected to the Board of Directors of Kerr-McGee, but do
not intend to submit the issue of reimbursement to a vote of security holders.
