REDMOND, Washington, May 4 /PRNewswire/ --

Microsoft Corp. (Nasdaq: MSFT) today announced that it has withdrawn its
proposal to acquire Yahoo! Inc. (Nasdaq: YHOO).

"We continue to believe that our proposed acquisition made sense for
Microsoft, Yahoo! and the market as a whole. Our goal in pursuing a
combination with Yahoo! was to provide greater choice and innovation in the
marketplace and create real value for our respective stockholders and
employees," said Steve Ballmer, chief executive officer of Microsoft.

"Despite our best efforts, including raising our bid by roughly US$5
billion, Yahoo! has not moved toward accepting our offer. After careful
consideration, we believe the economics demanded by Yahoo! do not make sense
for us, and it is in the best interests of Microsoft stockholders, employees
and other stakeholders to withdraw our proposal," said Ballmer.

"We have a talented team in place and a compelling plan to grow our
business through innovative new services and strategic transactions with
other business partners. While Yahoo! would have accelerated our strategy, I
am confident that we can continue to move forward toward our goals," Ballmer
said.

"We are investing heavily in new tools and Web experiences, we have
dramatically improved our search performance and advertiser satisfaction, and
we will continue to build our scale through organic growth and partnerships,"
said Kevin Johnson, Microsoft president for platforms and services.

Below is the text of the letter from Microsoft CEO Steve Ballmer to
Yahoo! CEO Jerry Yang.

REDMOND, Washington, May 4 /PRNewswire/ --

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 US$33.00 per share, reflecting again our belief in this collective
opportunity. This increase would have added approximately another US$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 US$5 billion or more, or at least another US$4 per share above our
US$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:

-- First, it would fundamentally undermine Yahoo!'s own strategy and 
       long-term viability by encouraging advertisers to use Google as opposed
       to your Panama paid search system.  This would also fragment your
       search advertising and display advertising strategies and the ecosystem
       surrounding them.  This would undermine the reliance on your display
       advertising business to fuel future growth.  

    -- Given this, it would impair Yahoo's ability to retain the talented
       engineers working on advertising systems that are important to our
       interest in a combination of our companies.  

    -- In addition, it would raise a host of regulatory and legal problems
       that no acquirer, including Microsoft, would want to inherit.  Among
       other things, this would consolidate market share with the 
       already-dominant paid search provider in a manner that would reduce
       competition and choice in the marketplace.  

    -- This would also effectively enable Google to set the prices for key
       search terms on both their and your search platforms and, in the
       process, raise prices charged to advertisers on Yahoo.  In addition to
       whatever resulting legal problems, this seems unwise from a business
       perspective unless in fact one simply wishes to use this as a vehicle
       to exit the paid search business in favor of Google.

    -- It could foreclose any chance of a combination with any other search
       provider that is not already relying on Google's search services.



Accordingly, your apparent plan to pursue such an arrangement in the
event of a proxy contest or exchange offer leads me to the firm decision not
to pursue such a path. Instead, I hereby formally withdraw Microsoft's
proposal to acquire Yahoo!.

We will move forward and will continue to innovate and grow our business
at Microsoft with the talented team we have in place and potentially through
strategic transactions with other business partners.

I still believe even today that our offer remains the only alternative
put forward that provides your stockholders full and fair value for their
shares. By failing to reach an agreement with us, you and your stockholders
have left significant value on the table.

But clearly a deal is not to be.

Thank you again for the time we have spent together discussing this.

Sincerely yours,
    /s/ Steven A. Ballmer

    Steven A. Ballmer
    Chief Executive Officer
    Microsoft Corporation
