   1.                                                   We note your investment
company risk factors beginning on page 41. Please disclose that
                                                        if you are found to be
operating as an unregistered investment company, you may be
                                                        required to change your
operations, wind down your operations, or register as an
                                                        investment company
under the Investment Company Act. Also include disclosure with
                                                        respect to the
consequences to investors if you are required to wind down your operations
                                                        as a result of this
status, such as the losses of the investment opportunity in a target
                                                        company, and any price
appreciation in the combined company. Please confirm that if
                                                        your facts and
circumstances change over time, you will update your disclosure to reflect
                                                        how those changes
impact the risk that you may be considered to be operating as an
                                                        unregistered investment
company.
