    Gentlemen:

    


    The
      undersigned stockholder, officer and director of Pantheon China Acquisition
      Corp. (“Company”), in consideration of EarlyBirdCapital, Inc. (“EBC”) entering
      into a letter of intent (“Letter of Intent”) to underwrite an initial public
      offering of the securities of the Company (“IPO”) and embarking on the IPO
      process, hereby agrees as follows (certain capitalized terms used herein are
      defined in paragraph 14 hereof):

    


    1. If
      the
      Company solicits approval of its stockholders of a Business Combination, the
      undersigned will vote all Insider Shares owned by her in accordance with the
      majority of the votes cast by the holders of the IPO Shares. 

    


    2. In
      the
      event that the Company fails to consummate a Business Combination within 24
      months from the effective date (“Effective Date”) of the registration statement
      relating to the IPO, the undersigned will (i) cause the Trust Fund (as defined
      in the Letter of Intent) to be liquidated and distributed to the holders of
      IPO
      Shares and (ii) take all reasonable actions within her power to cause the
      Company to liquidate as soon as reasonably practicable. The undersigned hereby
      waives any and all right, title, interest or claim of any kind in or to any
      distribution of the Trust Fund and any remaining net assets of the Company
      as a
      result of such liquidation with respect to his Insider Shares (“Claim”) and
      hereby waives any Claim the undersigned may have in the future as a result
      of,
      or arising out of, any contracts or agreements with the Company and will not
      seek recourse against the Trust Fund for any reason whatsoever.

    3. In
      order
      to minimize potential conflicts of interest which may arise from multiple
      affiliations, the undersigned agrees to present to the Company for its
      consideration, prior to presentation to any other person or entity, any suitable
      opportunity to acquire an operating business, until the earlier of the
      consummation by the Company of a Business Combination, the liquidation of the
      Company or until such time as the undersigned ceases to be an officer or
      director of the Company, subject to any pre-existing fiduciary and contractual
      obligations the undersigned might have.

    


    4. The
      undersigned acknowledges and agrees that the Company will not consummate any
      Business Combination which involves a company which is affiliated with any
      of
      the Insiders unless
      the Company obtains an opinion from an independent investment banking firm
      reasonably acceptable to EBC that the business combination is fair to the
      Company’s stockholders from a financial perspective.

     

    5. Neither
      the undersigned, any member of the family of the undersigned, nor any affiliate
      (“Affiliate”) of the undersigned will be entitled to receive and will not accept
      any compensation for services rendered to the Company prior to or in connection
      with the consummation of the Business Combination; provided that the undersigned
      shall be entitled to reimbursement from the Company for her out-of-pocket
      expenses incurred in connection with seeking and consummating a Business
      Combination.  

     

    6. Neither
      the undersigned, any member of the family of the undersigned, nor any Affiliate
      of the undersigned will be entitled to receive or accept a finder’s fee or any
      other compensation in the event the undersigned, any member of the family of
      the
      undersigned or any Affiliate of the undersigned originates a Business
      Combination. 

    


    7. The
      undersigned will escrow all of her Insider Shares acquired prior to the IPO
      (but
      not those to be acquired by her privately from the Company simultaneously with
      the IPO) for the three year period commencing on the Effective Date subject
      to
      the terms of a Stock Escrow Agreement which the Company will enter into with
      the
      undersigned and an escrow agent acceptable to the Company.

    


    8. The
      undersigned agrees to be an Executive Vice President and Director of the Company
      until the earlier of the consummation by the Company of a Business Combination
      or the liquidation of the Company. The undersigned’s biographical information
      furnished to the Company and EBC and attached hereto as Exhibit A is true and
      accurate in all respects, does not omit any material information with respect
      to
