EXHIBIT A High River Limited Partnership 767 Fifth Avenue, 47th Floor New York, New York 10153 December 9, 2004 Board of Directors Mylan Laboratories, Inc. 1500 Corporate Drie Suite 400 Canonsburg, Pennsylvania 15317-8574 Re: Mylan Laboratories, Inc. (`Mylan") Gentlemen: We have reviewed today's announcement indicating that King will restate its financial statements, which, as you know, constitutes a failure of a condition to closing of the proposed Mylan/King transaction. Mylan continues to leave shareholders uninformed as to its position on this matter. We view this lack of disclosure to shareholders as reprehensible and insulting. Even more reprehensible, in our view, is your determination to ignore our proposal to purchase Mylan at $20 per share on terms that would allow you to continue to seek additional buyers for Mylan. We hereby advise you that our proposal still stands and that, as previously indicated, if you determine that you cannot at this time put Mylan up for sale or grant due diligence because of the current King contract, we are willing to stand by our $20 per share proposal pending either the determination of Mylan shareholders to vote the King transaction down or your determination that you are legally free to put Mylan up for sale and grant due diligence. We will continue to urge all Mylan shareholders to vote against the proposed Mylan/King transaction, which we believe is extremely risky for Mylan. Very truly yours, /s/ Carl C. Icahn Carl C.
