SCHEDULE 13D/A

This Amendment No. 1 amends the Schedule 13D filed on February 25, 2011 (the “Schedule 13D”) by LaBranche & Co Inc. (n/k/a Cowen Structured Holdings LLC) (the “Reporting Person”). Capitalized terms used herein not otherwise defined shall have the meaning ascribed to them in the Schedule 13D. The irrevocable proxy granted to the Reporting Person pursuant to the Parent Voting Agreement has been terminated in accordance with its terms. Consequently, the Reporting Person is no longer the beneficial owner of any shares of Parent Common Stock. Accordingly, this Amendment No. 1 is the Reporting Person’s final amendment to the Schedule 13D and is an exit filing.

Item 4.	Purpose of Transaction
Item 4 of the Schedule 13D is hereby supplemented by adding the following: On June 28, 2011, the parties to the Merger Agreement consummated the Merger Agreement (the “Merger”). Pursuant to the terms of the Merger Agreement, each share of Company Common Stock that was issued and outstanding immediately prior to the effective time of the Merger (other than shares of Company Common Stock that were owned by, or held in the treasury of, the Reporting Person) was converted into the right to receive 0.9980 fully paid and nonassessable shares of Parent Common Stock. Furthermore, pursuant to the terms of the Parent Voting Agreement, the proxy granted to the Reporting Person was terminated at the effective time of the Merger. Consequently, the Reporting Person is no longer the beneficial owner of any shares of Parent Common Stock.

Item 5.	Interest in Securities of the Issuer.
Item 5 of the Schedule 13D is hereby amended and restated in its entirety by the following: (a) and (b) The responses of the Reporting Person to Rows (7) through (13) of the cover page of this Amendment No. 1 are incorporated herein by reference. As of June 28, 2011, following the consummation of the Merger, the Reporting Person owns no shares of Parent Common Stock. Except as set forth on Schedule 1 to the Schedule 13D or as a result of the Merger, to the knowledge of the Reporting Person, no Schedule 1 Person beneficially owns shares of Parent Common Stock. (c) Except as a result of the Merger, neither the Reporting Person nor, to the knowledge of the Reporting Person, any Schedule 1 Person has acquired or disposed of any shares of Parent Common Stock in the past 60 days. (d) Not applicable. (e) June 28, 2011
