add my Yahoo! shares that I own to this "Yahoo! Plan B" Group in order for the group to negotiate the highest possible price for my Yahoo! shares. I realize that this is an informal pledge, but I represent that I truly own the Yahoo! shares I say I do and am willing to be contacted to verify this. I understand that Eric Jackson or someone else from the "Yahoo! Plan B" Group will contact me later about the best possible price they are able to negotiate from a buyer, before I will agree to tender my shares.
