2.
              Agreements and Covenants of the
                Company.
                The Company hereby agrees and covenants
                to:


(a)  Give
      all
      instructions to the Trustee hereunder in writing, signed by the Company’s
      President or Chairman of the Board. In addition, except with respect to its
      duties under paragraph 1(i) above, the Trustee shall be entitled to rely on,
      and
      shall be protected in relying on, any verbal or telephonic advice or instruction
      which it in good faith believes to be given by any one of the persons authorized
      above to give written instructions, provided that the Company shall promptly
      confirm such instructions in writing;




(b)  Hold
      the
      Trustee harmless and indemnify the Trustee from and against, any and all
      expenses, including reasonable counsel fees and disbursements, or loss suffered
      by the Trustee in connection with any action, suit or other proceeding brought
      against the Trustee involving any claim, or in connection with any claim or
      demand which in any way arises out of or relates to this Agreement, the services
      of the Trustee hereunder, or the Property or any income earned from investment
      of the Property, except for expenses and losses resulting from the Trustee’s
      gross negligence or willful misconduct. Promptly after the receipt by the
      Trustee of notice of demand or claim or the commencement of any action, suit
      or
      proceeding, pursuant to which the Trustee intends to seek indemnification under
      this paragraph, it shall notify the Company in writing of such claim
      (hereinafter referred to as the “Indemnified Claim”). The Trustee shall have the
      right to conduct and manage the defense against such Indemnified Claim,
      provided, that the Trustee shall obtain the consent of the Company with respect
      to the selection of counsel, which consent shall not be unreasonably withheld.
      The Company may participate in such action with its own counsel;
      and




(c)  Pay
      the
      Trustee an initial acceptance fee of $1,000 and an annual fee of $3,000 (it
      being expressly understood that the Property shall not be used to pay such
      fee).
      The Company shall pay the Trustee the initial acceptance fee and first year’s
      fee at the consummation of the IPO and thereafter on the anniversary of the
      Effective Date. The Trustee shall refund to the Company the fee (on a pro rata
      basis) with respect to any period after the liquidation of the Trust Fund.
      The
      Company shall not be responsible for any other fees or charges of the Trustee
      except as may be provided in paragraph 2(b) hereof (it being expressly
      understood that the Property shall not be used to make any payments to the
      Trustee under such paragraph).




3.
              Limitations of Liability.
                The Trustee shall have no responsibility or liability
                to:


(a)  Take
      any
      action with respect to the Property, other than as directed in paragraph 1
      hereof and the Trustee shall have no liability to any party except for liability
      arising out of its own gross negligence or willful misconduct;




(b)  Institute
      any proceeding for the collection of any principal and income arising from,
      or
      institute, appear in or defend any proceeding of any kind with respect to,
      any
      of the Property unless and until it shall have received instructions from the
      Company given as provided herein to do so and the Company shall have advanced
      or
      guaranteed to it funds sufficient to pay any expenses incident
      thereto;




(c)  Change
      the investment of any Property, other than in compliance with
      paragraph 1(c);




(d)  Refund
      any depreciation in principal of any Property;




2




(e)  Assume
      that the authority of any person designated by the Company to give instructions
      hereunder shall not be continuing unless provided otherwise in such designation,
      or unless the Company shall have delivered a written revocation of such
      authority to the Trustee;




(f)  The
      other
      parties hereto or to anyone else for any action taken or omitted by it, or
      any
      action suffered by it to be taken or omitted, in good faith and in the exercise
      of its own best judgment, except for its gross negligence or willful misconduct.
      The Trustee may rely conclusively and shall be protected in acting upon any
      order, notice, demand, certificate, opinion or advice of counsel (including
      counsel chosen by the Trustee), statement, instrument, report or other paper
      or
      document (not only as to its due execution and the validity and effectiveness
      of
      its provisions, but also as to the truth and acceptability of any information
      therein contained) which is believed by the Trustee, in good faith, to be
      genuine and to be signed or presented by the proper person or persons. The
      Trustee shall not be bound by any notice or demand, or any waiver, modification,
      termination or rescission of this agreement or any of the terms hereof, unless
      evidenced by a written instrument delivered to the Trustee signed by the proper
      party or parties and, if the duties or rights of the Trustee are affected,
      unless it shall give its prior written consent thereto;




(g)  Verify
      the correctness of the information set forth in the Registration Statement
      or to
      confirm or assure that any acquisition made by the Company or any other action
      taken by it is as contemplated by the Registration Statement; and




(h)  Pay
      any
      taxes on behalf of the Trust Account (it being expressly understood that the
      Property shall not be used to pay any such taxes and that such taxes, if any,
      shall be paid by the Company from funds not held in the Trust
      Account).




4.
              Termination.
                This Agreement shall terminate as
                follows:


(a)  If
      the
      Trustee gives written notice to the Company that it desires to resign under
      this
      Agreement, the Company shall use its reasonable efforts to locate a successor
      trustee. At such time that the Company notifies the Trustee that a successor
      trustee has been appointed by the Company and has agreed to become subject
      to
      the terms of this Agreement, the Trustee shall transfer the management of the
      Trust Account to the successor trustee, including but not limited to the
      transfer of copies of the reports and statements relating to the Trust Account,
      whereupon this Agreement shall terminate; provided, however, that, in the event
      that the Company does not locate a successor trustee within ninety days of
      receipt of the resignation notice from the Trustee, the Trustee may submit
      an
      application to have the Property deposited with the United States District
      Court
      for the Southern District of New York and upon such deposit, the Trustee shall
      be immune from any liability whatsoever;




(b)  At
      such
      time that the Trustee has completed the liquidation of the Trust Account in
      accordance with the provisions of paragraph 1(i) hereof, and distributed the
      Property in accordance with the provisions of the Termination Letter, this
      Agreement shall terminate except with respect to Paragraph 2(b); or




(c)  On
      such
      date after July 13, 2007 when the Trustee deposits the Property with the United
      States District Court for the Southern District of New York in the event that,
      prior to such date, the Trustee has not received a Termination Letter from
      the
      Company pursuant to paragraph 1(i).


5.
                Miscellaneous.


(a)  The
      Company and the Trustee each acknowledge that the Trustee will follow the
      security procedures set forth below with respect to funds transferred from
      the
      Trust Account. Upon receipt of written instructions, the Trustee will confirm
      such instructions with an Authorized Individual at an Authorized Telephone
      Number listed on the attached Exhibit C.  The Company and the Trustee
      will each restrict access to confidential information relating to such security
      procedures to authorized persons. Each party must notify the other party
      immediately if it has reason to believe unauthorized persons may have obtained
      access to such information, or of any change in its authorized personnel. In
      executing funds transfers, the Trustee will rely upon account numbers or other
      identifying numbers of a beneficiary, beneficiary’s bank or intermediary bank,
      rather than names. The Trustee shall not be liable for any loss, liability
      or
      expense resulting from any error in an account number or other identifying
      number, provided it has accurately transmitted the numbers
      provided.




3




(b)  This
      Agreement shall be governed by and construed and enforced in accordance with
      the
      laws of the State of New York, without giving effect to conflict of laws. It
      may
      be executed in several counterparts, each one of which shall constitute an
      original, and together shall constitute but one instrument.




(c)  This
      Agreement contains the entire agreement and understanding of the parties hereto
      with respect to the subject matter hereof. This Agreement or any provision
      hereof may only be changed, amended or modified by a writing signed by each
      of
      the parties hereto; provided, however, that no such change, amendment or
      modification may be made without the prior written consent of Sunrise. As to
      any
      claim, cross-claim or counterclaim in any way relating to this Agreement, each
      party waives the right to trial by jury.




(d)  The
      parties hereto consent to the jurisdiction and venue of any state or federal
      court located in the City of New York for purposes of resolving any disputes
      hereunder.




(e)  Any
      notice, consent or request to be given in connection with any of the terms
      or
      provisions of this Agreement shall be in writing and shall be sent by express
      mail or similar private courier service, by certified mail (return receipt
      requested), by hand delivery or by facsimile transmission:
