**Acknowledgment
      and Agreement**





I,
      the
      undersigned subscriber (hereinafter referred to as “I”, “me”, “my”, “mine”, or
“Subscriber”)  hereby acknowledge and agree, for the specific benefit
      and reliance of the Company and its organizers, members, managers and
      controlling persons, as follows:





The
      Shares have not been registered under the Securities Act of 1933, as amended
      (the “Act”) or any state, including New York State, securities
      laws.  The Shares have not been qualified or registered with the
      office of the Attorney General of New York State or any other state securities
      agency.  The Shares may not be transferred unless registered under the
      Act or qualified with the securities regulatory agency of any state, which
      has
      jurisdiction over any such transfer unless an exemption from such registration
      or qualification is available. Transfer of the Shares is further restricted
      by
      this Agreement. I shall hold harmless the Company and its officers, directors,
      employees, “affiliates” (as defined in SEC rules) and controlling persons
      against loss or liability arising from the disposition, in violation of this
      Agreement, of the Shares subscribed for by this Agreement.





**INVESTOR
      SUITABILITY:** You must be an “accredited investor” as defined in Rule
      501(a) of Regulation D of the Securities Act of 1933, as amended, to subscribe
      for Shares under this Offering. An “accredited investor” is an investor who is
      able to check either box A, B or C under Section 2 below.





An
      investment in the Shares of the Company involves significant risk, including
      those set forth in this Private Placement Memorandum;






1





The
      “Shares” are “restricted securities” (as defined in Rule 144 of the Securities
      Act of 1933, as amended) and may not be sold, encumbered, pledged, transferred
      or otherwise disposed without registration of the Shares under the Securities
      Act of 1933, as amended, and applicable state securities laws, or qualification
      for an exemption under federal securities laws and applicable New York State
      securities laws, and without a legal opinion satisfactory to the Company and
      opining that the Shares may be sold, encumbered, pledged, transferred or
      otherwise disposed without registration of the Shares under the Securities
      Act
      of 1933, as amended, and applicable state securities laws.





Legends
      shall be placed on any certificates, which evidence the restrictions
      under


federal
      and state securities laws and rules on the sale, transfer, encumbering or other
      disposition of the Shares; I had the opportunity to ask questions of and receive
      answers from the Company and its organizers about the offering, as I deemed
      necessary, to evaluate the merits and risks of an investment in the
      Company.





I,
      or my
      purchaser representative, if any, received answers to our questions to our
      full
      satisfaction and obtained such additional information as we
      requested.  I consulted with investment, accounting, legal, and/or tax
      advisors, as I deemed appropriate and necessary, to make a decision to invest
      in
      the Company.





Neither
      the Company, nor any of its organizers, members, managers or controlling persons
      has made any representations or warranties, oral, written or otherwise,
      concerning the Company or the offering, other than those contained in the
      Private Placement Memorandum.  In subscribing for the Shares, I am not
      relying on any information, other than the results of my own or my purchaser
      representative’s independent review of the Private Placement Memorandum of the
      Company and the Private Placement Memorandum and the exhibits thereto, the
      Operating Agreement, and any other written information provided by the Company
      to me or my purchaser’s representative at either my request or the request of my
      purchaser’s representative.
