BlackRock Announces Pricing of $250 Million Convertible Debt Offering

New York, February 17, 2005 – BlackRock, Inc. (NYSE:BLK) today announced the pricing of its private offering of $250 million aggregate principal amount of convertible debentures, which will be due in 2035. The debentures will bear interest at a rate of 2.625% per annum.

Prior to February 15, 2009, the debentures will be convertible, only under certain conditions, at the option of the holder into cash and, in certain circumstances, shares of BlackRock’s class A common stock at an initial conversion rate of 9.7282 shares of class A common stock per $1,000 principal amount of debentures, which represents a premium of 32.5% to the last reported sale price of BlackRock’s class A common stock on February 16, 2005 of $77.58. On and after February 15, 2009, the debentures will be convertible at any time prior to maturity at the option of the holder into cash and, in certain circumstances, shares of class A common stock at the above initial conversion rate, subject to adjustments.

Beginning February 20, 2010, BlackRock may redeem any of the debentures at a redemption price of 100% of their principal amount, plus accrued and unpaid interest, including contingent interest and accrued and unpaid liquidated damages, if any. Holders may require BlackRock to repurchase the debentures at a repurchase price equal to 100% of their principal amount plus accrued and unpaid interest, including contingent interest and accrued and unpaid liquidated damages, if any, on February 15, 2010, 2015, 2020, 2025 and 2030, or at any time prior to their maturity upon the occurrence of certain events.

BlackRock plans to use the net proceeds of the offering to repay its $150 million bridge promissory note, the proceeds of which were used to fund a portion of the purchase price for its acquisition of SSRM Holdings, Inc. on January 31, 2005, and for general corporate purposes. BlackRock expects this offering to close on February 23, 2005.

The debentures will be offered only to qualified institutional buyers in accordance with Rule 144A under the Securities Act of 1933. The debentures and the class A common stock issuable in certain circumstances upon conversion of the debentures will not be registered under the Securities Act of 1933 or the securities laws of any other jurisdiction

and, unless they are registered, may be offered and sold only in transactions that are exempt from registration under the Securities Act of 1933 or the securities laws of any other jurisdiction.

This press release does not constitute an offer to sell or a solicitation of an offer to buy the debentures.
