Google Deal Void If Icahn Wins Control Of Yahoo

Microsoft (NSDQ: MSFT) and Yahoo (NSDQ: YHOO) just got a lot more complicated -- and expensive -- thanks to the search ad outsourcing deal Yahoo struck with Google late Thursday.

According the deal's fine print, disclosed Friday by Yahoo in a Securities and Exchange filing, Google is free to tear up the pact if a majority of Yahoo's current board is replaced at the behest of a third party, such as Icahn, at either of the company's next two shareholder meetings.
