Other Events

On April 8, 2011, the acquisition of Genzyme Corporation by GC Merger Corp., a wholly-owned subsidiary of Sanofi Aventis, became effective. As a result, Genzyme Corporation will no longer be an underlying constituent of the Biotech HOLDRS Trust. In connection with the acquisition, Genzyme Corporation shareholders will receive $74.00 in cash and one Contingent Value Right (CVR) for each share of Genzyme Corporation. The Bank of New York Mellon will receive $1,036.00 in cash and 14 CVRs for the 14 shares of Genzyme Corporation per 100 share round-lot of Biotech HOLDRS.

The CVRs will entitle the holder to receive additional cash payments if specified governmental approvals and production goals for Genzyme Corporation’s pharmaceutical products are achieved.

Neither GC Merger Corp. nor Sanofi Aventis will become underlying constituents of the Biotech HOLDRS Trust as a result of the acquisition.
