Amended and Restated 2007 Equity Incentive Plan (the “Plan”) and, pursuant to Rule 416(a) under the Securities Act of 1933, as amended (the “Securities Act”), an indeterminate amount of additional Common Units that may be offered and issued under the Plan to prevent dilution resulting from unit splits, unit distributions or similar transactions.

EXPLANATORY NOTE

This Registration Statement on Form S–8 is being filed for the purpose of registering an additional 20,706,600 Common Units of The Blackstone Group L.P. (the “Partnership”) reserved for issuance under The Blackstone Group L.P. Amended and Restated 2007 Equity Incentive Plan (the “Plan”). These additional Common Units are additional securities of the same class as other securities for which an original registration statement (File No. 333-143948) on Form S-8 was filed with the Securities and Exchange Commission (the “Commission”) on June 21, 2007 and additional registration statements (File No. 333-157635, File No. 333-165115, File No. 333-172451 and File No. 333-179775) were filed with the Commission on March 2, 2009, March 1, 2010, February 25, 2011 and February 28, 2012. These additional Common Units have become reserved for issuance as a result of the operation of the “evergreen” provision of the Plan, which provides that the total number of units subject to the Plan will be increased on the first day of each fiscal year pursuant to a specified formula.

Pursuant to General Instruction E to Form S-8, the contents of such earlier registration statements are incorporated by reference into this Registration Statement, except that the provisions contained in Part II of such earlier registration statement are modified as set forth in this Registration Statement.

Item 6. Indemnification of Directors and Officers.

Under the Amended and Restated Agreement of Limited Partnership of the Partnership, as amended, in most circumstances the Partnership will indemnify the following persons, to the fullest extent permitted by law, from and against all losses, claims, damages, liabilities, joint or several, expenses (including legal fees and expenses), judgments, fines, penalties, interest, settlements or other amounts: the Partnership’s general partner; any departing general partner; any person who is or was an affiliate of a general partner or any departing general partner; any person who is or was a member, partner, tax matters partner, officer, director, employee, agent, fiduciary or trustee of the Partnership or its subsidiaries, the general partner or any departing general partner or any affiliate of the Partnership or its subsidiaries, the general partner or any departing general partner; any person who is or was serving at the request of a general partner or any departing general partner or any affiliate of a general partner or any departing general partner as an officer, director, employee, member, partner, agent, fiduciary or trustee of another person; or any person designated by the Partnership’s general partner. The Partnership has agreed to provide this indemnification to the extent such person acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the Partnership, and with respect to any alleged conduct resulting in a criminal proceeding against such person, to deny indemnification if such person had reasonable cause to believe that his or her conduct was unlawful. The Partnership has also agreed to provide this indemnification for criminal proceedings. Any indemnification under these provisions will only be out of the Partnership’s assets. Unless it otherwise agrees, the general partner of the Partnership will not be personally liable for, or have any obligation to contribute or loan funds or assets to the Partnership to enable it to effectuate indemnification. The Partnership may purchase insurance against liabilities asserted against and expenses incurred by persons for the Partnership’s activities, regardless of whether the Partnership would have the power to indemnify the person against liabilities under the Amended and Restated Agreement of Limited Partnership of the Partnership, as amended.
