TO THE STOCKHOLDERS,

         The enclosed brochure describes Anadarko's Dividend Reinvestment and
Stock Purchase Plan. By reinvesting Anadarko's dividends you can purchase common
stock at a 5% discount. You can also purchase additional shares of Anadarko
common stock under the plan with no transaction costs or brokerage fees. See the
enclosed brochure for the details.

         Anadarko has amended the plan to limit some of its administrative
costs. If you are a registered stockholder who owns less than 400 shares of
Anadarko common stock you will be AUTOMATICALLY ENROLLED in the dividend
reinvestment plan. In addition, you may only receive an account statement once
each year although you will have access to your account via the internet. You
may elect not to participate in the plan and to receive all your Anadarko
dividends directly. If you do not want to participate in the dividend
reinvestment plan please notify the administrator as provided in the enclosed
brochure.

         I believe Anadarko's plan is a benefit to you. It will provide you with
convenience in investing and an easy way to increase your holdings in Anadarko
stock. As always, I appreciate your investment in Anadarko.
