Dear Fellow Stockholder:

We have previously sent to you proxy material for the Special Meeting of Inktomi Corporation to be held on March 19, 2003. Your Board of Directors has unanimously recommended that shareholders vote in favor of the proposed merger with Yahoo! Inc.

Since approval of the merger requires the affirmative vote of the holders of a majority of the outstanding shares of Inktomi’s common stock, your vote is important, no matter how many or how few shares you may own. Whether or not you have already done so, please sign, date and return the enclosed proxy card today in the envelope provided.

Very truly yours,

/s/ David C. Peterschmidt

David C. Peterschmidt
Chairman, President and Chief Executive Officer
