May 3, 2008

Mr. Jerry Yang

CEO and Chief Yahoo

Yahoo Inc.

701 First Avenue

Sunnyvale, CA 94089

Dear Jerry:

After over three months, we have reached the conclusion of the process regarding a possible combination of Microsoft and Yahoo.

I first want to convey my personal thanks to you, your management team, and Yahoo's Board of Directors for your consideration of our proposal. I appreciate the time and attention all of you have given to this matter, and I especially appreciate the time that you have invested personally. I feel that our discussions this week have been particularly useful, providing me for the first time with real clarity on what is and is not possible.

I am disappointed that Yahoo has not moved towards accepting our offer. I first called you with our offer on January 31 because I believed that a combination of our two companies would have created real value for our respective shareholders and would have provided consumers, publishers, and advertisers with greater innovation and choice in the marketplace. Our decision to offer a 62 percent premium at that time reflected the strength of these convictions.

In our conversations this week, we conveyed our willingness to raise our offer to $33.00 per share, reflecting again our belief in this collective opportunity. This increase would have added approximately another $5 billion of value to your shareholders, compared to the current value of our initial offer. It also would have reflected a premium of over 70 percent compared to the price at which your stock closed on January 31. Yet it has proven insufficient, as your final position insisted on Microsoft paying yet another $5 billion or more, or at least another $4 per share above our $33.00 offer.

Also, after giving this week's conversations further thought, it is clear to me that it is not sensible for Microsoft to take our offer directly to your shareholders. This approach would necessarily involve a protracted proxy contest and eventually an exchange offer. Our discussions with you have led us to conclude that, in the interim, you would take steps that would make Yahoo undesirable as an acquisition for Microsoft.

We regard with particular concern your apparent planning to respond to a "hostile" bid by pursuing a new arrangement that would involve or lead to the outsourcing to Google of key paid Internet search terms offered by Yahoo today. In our view, such an arrangement with the dominant search provider would make an acquisition of Yahoo undesirable to us for a number of reasons:
