       Exhibits

   1.                                                   With respect to Exhibit
5.2, please delete as inappropriate the assumptions contained in
                                                        Section 12 of Schedule

   2.                                                   We note that you have
revised your disclosure to remove the redemption limitation from
                                                        your organizational
documents and related disclosure in the prospectus. Please tell us
                                                        why you believe you do
not need to retain this redemption limitation in order to, at a
                                                        minimum, maintain your
exemption from compliance with Rule 419. In this regard, you
                                                        disclose that investors
in this offering will not be entitled to the protections normally

      afforded to investors in Rule 419 blank check offerings. However, removal
of this
      redemption limitation seems to heighten the risk that your offering must
comply with Rule
      419, particularly considering you state that your securities may not be
or may not continue
      to be listed on Nasdaq, which might cause your securities to be "penny
stock," pursuant to
      Exchange Act Rule 3a51-1. Please advise.
