Remarks:
On September 29, 2006, the corporation then known as BlackRock, Inc. ("Old BlackRock") merged with its wholly-owned subsidiary, BlackRock Merger Sub, Inc., with Old BlackRock surviving the merger. As a result of that merger, New BlackRock, Inc. (now named BlackRock, Inc.) became the successor and holding company of Old BlackRock. The merger did not alter the proportionate ownership of the capital stock. Each share of Class A Common Stock and Class B Common Stock of Old BlackRock issued and outstanding prior to the merger was converted into one share of Common Stock.

Note: File three copies of this Form, one of which must be manually signed. If space is insufficient, see Instruction 6 for procedure.
