On December 7, 2011, Daniel S. Och, Chairman and Chief Executive Officer of Och-Ziff Capital Management Group LLC (the “Company”) and certain other executive managing directors of the Company plan to enter into separate individual plans, each intended to comply with Rule 10b5-1 under the Securities Exchange Act of 1934, as amended, providing for the purchase of up to an aggregate amount of $20 million of Class A Shares representing limited liability company interests of the Company. 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. A Rule 10b5-1 trading plan would generally permit the purchase of Class A Shares at times when the executive managing director, including Mr. Och, might otherwise be prevented from doing so under certain securities laws. Any Rule 10b5-1 trading plan may be terminated or discontinued at any time.

Any forward-looking statements contained in this Current Report on Form 8-K are based upon historical information and on the Company’s current plans, estimates and expectations. The inclusion of this or any other forward-looking information should not be regarded as a representation by the Company or any other person that the future plans, estimates or expectations contemplated by the Company will be achieved. The Company cautions that forward-looking statements are subject to numerous assumptions, estimates, risks and uncertainties, including but not limited to: global economic, business, market and geopolitical conditions, including Euro-zone sovereign debt issues; U.S. and foreign regulatory developments relating to, among other things, financial institutions and markets, government oversight and taxation; the conditions impacting the hedge fund industry; the Company’s ability to successfully compete for fund investors, assets, professional talent and investment opportunities; the Company’s ability to retain its partners, managing directors and investment professionals; the Company’s successful formulation and execution of its business and growth strategies; the Company’s ability to appropriately manage conflicts of interest and tax and other regulatory factors relevant to the Company’s business; as well as assumptions relating to the Company’s operations, investment performance, financial results, financial condition, business prospects, growth strategy and liquidity.

If one or more of these or other risks or uncertainties materialize, or if the Company’s assumptions or estimates prove to be incorrect, the Company’s actual results may vary materially from those indicated in these statements. These factors are not and should not be construed as exhaustive and should be read in conjunction with the other cautionary statements and risks that are included in the Company’s filings with the Securities and Exchange Commission (“SEC”), including but not limited to the Company’s Annual Report on Form 10-K for the year ended December 31, 2010 filed with the SEC on February 28, 2011.
