New York, NY. December 7, 2011—Och-Ziff Capital Management Group LLC (NYSE: OZM) (“Och-Ziff” or the “Company”) today announced that Daniel S. Och, Chairman and Chief Executive Officer, and certain other executive managing directors of the Company each plan to enter into separate individual Rule 10b5-1 trading plans providing for the purchase of up to an aggregate amount of $20 million of Class A Shares representing limited liability company interests. Under the proposed trading plans, Mr. Och and certain executive managing directors may purchase Class A Shares over time in the open market, in privately negotiated transactions or otherwise. The amount and timing of any purchases will depend on a number of factors, including the price of the Company’s Class A Shares, trading volume and general market conditions.

The trading plans may be terminated or discontinued at any time.
