Item 3.02
Unregistered Sales of Equity Securities
.
McMoRan Exploration Co. (McMoRan) agreed in privately negotiated transactions to induce conversion of 16,574 shares (approximately 43% of the total outstanding) of its 8% Convertible Perpetual Preferred Stock (the 8% Preferred Stock) with a liquidation preference of approximately $16.6 million into approximately 2.4 million shares of McMoRan common stock (at the specified conversion rate equal to 146.1454 shares of common stock per share of the 8% Preferred Stock).  To induce the early conversion of these shares of 8% Preferred Stock, McMoRan will pay an aggregate $3.3 million in cash to the holders of these shares.  These induced conversions were exempt from registration by virtue of the exemption provided under Section 3(a)(9) of the Securities Act of 1933.
Preferred annual dividend savings following these transactions approximate $1.3 million.  After giving effect to these transactions, McMoRan will have outstanding approximately 22,000 shares of 8% Preferred Stock, approximately 1.6 million shares of 6¾% Mandatory Convertible Preferred Stock and approximately 95.5 million shares of common stock.  Assuming conversion of McMoRan's remaining 8% Preferred Stock and the outstanding 6¾% Mandatory Convertible Preferred Stock, McMoRan would have between approximately 109 million and 111 million common shares outstanding (based on a defined market price of McMoRan's common stock calculated at the time of conversion).
