Submission of Matters to a Vote of Security Holders.

On June 15, 2011, LaBranche & Co Inc. (the “Company”) held a special meeting of its stockholders in order to vote upon the following proposals:

(1) proposal to approve and adopt the Agreement and Plan of Merger, dated as of February 16, 2011, by and among the Company, Cowen Group, Inc. and Louisiana Merger Sub, Inc., and approve the merger contemplated thereby (the “Merger Proposal”); and

(2) proposal to adjourn the special meeting, if necessary and appropriate, to solicit additional proxies if there are not sufficient votes to approve the foregoing proposal (the “Adjournment Proposal”).

As of May 4, 2011, the record date for determining the Company stockholders entitled to vote on the proposals presented at the special meeting, there were 40,931,997 shares of Company common stock entitled to vote at the special meeting. At the special meeting, holders of 32,189,426 shares of Company common stock entitled to vote were represented in person or by proxy, constituting a quorum. The holders of a majority of the Company common stock outstanding and entitled to vote were required to vote in favor of the Merger Proposal.

The stockholders approved the Merger Proposal based on the following results as certified by the inspector of elections:

Since the Merger Proposal was approved, it was not necessary to consider the Adjournment Proposal and the results of the vote on the Adjournment Proposal were not announced at the special meeting.
