(f) Where an Acquiring Fund and its Advisory Group, in the aggregate, hold more than 10% of an Acquired Fund’s total outstanding voting securities, each of those holders shall vote its securities in the same proportion as the vote of all other holders of such securities, unless as otherwise provided under the Rule.

(g) The requirements set forth in Sections 3(d), 3(e) and 3(f) shall not apply where the Acquiring Fund’s full portfolio is sub-advised by any affiliate of BlackRock, Inc.

(h) An Acquiring Fund shall provide an Acquired Fund with information regarding the investments in the Acquired Fund held by the Acquiring Fund and its Advisory Group, including the amounts of such investments, upon the Acquired Fund’s reasonable request.
