        <footnote id="F1">Issuance of shares in settlement of 83.33% of a cash denominated award made in 2002 under the BlackRock, Inc. 2002 Long-Term Retention and Incentive Plan (the &quot;2002 LTIP&quot;) as previously discussed in BlackRock?s proxy statement for that period.  Awards were paid out approximately 50 months after the first grant under the 2002 LTIP although the performance criteria contained in the 2002 LTIP were satisfied on March 31, 2005.  On January 16, 2007, the Management Development and Compensation Committee approved January 29, 2007 as the payment date pursuant to the 2002 LTIP.  The number of shares of Common Stock reflected above was determined pursuant to the terms of the 2002 LTIP by dividing 83.33% of the vested 2002 LTIP award by $169.17, the closing price of Common Stock on January 26, 2007.</footnote>
        <footnote id="F2">Includes 13,185 shares of restricted Common Stock granted under the BlackRock, Inc. 1999 Stock Award and Incentive Plan (the &quot;Incentive Plan&quot;), vesting on 12/15/07. Also includes 15,689 Restricted Stock Units granted under the Incentive Plan, vesting in equal installments on 1/31/07, 1/31/08 and 1/31/09, and 18,358 Restricted Stock Units granted under the Incentive Plan, vesting in equal installments on 1/31/08, 1/31/09 and 1/31/10. Each Restricted Stock Unit is payable solely by delivery of an equal number of shares of Common Stock.</footnote>
        <footnote id="F3">Represents the disposition of Common Stock to BlackRock, Inc. (as approved by the Management Development and Compensation Committee) pursuant to the exercise of put rights pursuant to the 2002 LTIP.  The 2002 LTIP allowed award beneficiaries, following a period of approximately 50 months from the initial grant date, to put Common Stock to be received under the 2002 LTIP to BlackRock, Inc. on the payment date at the same price per share as that used for calculating the number of shares to be paid.</footnote>
