    Re:
      Korea
      Milestone Acquisition Corporation 

    


    Gentlemen:
      

    


    This
      letter will confirm the agreement of the undersigned to enter into a Rule
      10b5-1 Plan to purchase warrants (“Warrants”) of Korea Milestone Acquisition
      Corporation (“Company”) included in the units (“Units”) being sold in the
      Company’s initial public offering (“IPO”) upon the terms and conditions set
      forth herein. Each Unit is comprised of two shares of common stock of the
      Company (“Common Stock”) and one Warrant. The shares of Common Stock and
      Warrants will not be separately tradable until the 90th
      day
      after the date of the prospectus relating to the Company’s IPO, unless Broadband
      Capital Management LLC (“Broadband”) informs the Company of its decision to
      allow earlier separate trading. 

    


    The
      undersigned agrees that this letter agreement (which may be evidenced by
      original or facsimile counterpart signatures hereto) constitutes an irrevocable
      order for Daewoo Securities Co., Ltd. (the “Broker”) to purchase for the
      undersigned’s account during the period commencing on the earlier
      of (i) ten (10) months from the effective date of the prospectus related to
      the
      IPO and (ii) the Company’s filing of a Form 6-K containing the proxy statement
      relating to the Company’s initial business combination (the “Commencement
      Date”), and ending sixty (60) calendar days following the Commencement Date
(such
      period is hereinafter referred to as the “Purchase Period”) up to 5,000,000
      Warrants (“Maximum Warrant Purchase”). The undersigned further agrees that this
      letter agreement constitutes an irrevocable “good till cancel” limit order at a
      price of $2.30 per Warrant. The
      undersigned agrees to fund the undersigned’s account fully on or
      before the effective date of the Company’s registration statement on Form
      F-1 in connection with the IPO. The
      Broker shall provide to Broadband, on a monthly basis, statements confirming
      that there are sufficient funds in the brokerage accounts where the Warrants
      will be purchased to satisfy the Maximum Warrant Purchase. On each day on which
      the NASDAQ Stock Market (the “Exchange”) is open for trading during the Purchase
      Period, Broker shall use commercially reasonable efforts to purchase, as agent
      and for the account of the undersigned, up to 5,000,000 Warrants at a price
      of
      $2.30 per Warrant and agrees to fill such order in such amounts and at such
      times as it may determine, in its sole discretion, during the Purchase Period
      and in compliance with Regulation M under the Securities Exchange Act of 1934,
      as amended, and all applicable laws.

    


    The
      undersigned may notify the Broker that all or part of the Maximum Warrant
      Purchase will be made by Dawin Technology, Inc., an affiliate of the undersigned
      (“Dawin”), which has an account with the Broker and, in such event, the Broker
      will make such purchase on behalf of Dawin; provided, however, that the
      undersigned hereby agrees to make payment of the purchase price of such purchase
      in the event that Dawin fails to make such payment. 

    


    The
      Broker will promptly notify the undersigned of any purchase of Warrants
      hereunder so that the undersigned can comply with applicable reporting
      requirements, if any, on a timely basis. The undersigned agrees that he shall
      not sell or transfer the Warrants until after the consummation of a merger,
      capital stock exchange, asset acquisition or other similar business combination
      with an operating business and acknowledges that, at the option of Broadband,
      the certificates for such Warrants shall contain a legend indicating such
      restriction on transferability. 

     

    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

    
The
      Company and the Broker shall provide to the Securities and Exchange Commission
      (the “Commission”) promptly upon request, and in no event more than 30 days of
      such request, a daily time-sequenced schedule of all Warrant purchases made
      pursuant to this letter agreement, on a transaction-by-transaction basis,
      including: (i) size, broker (if any), time of execution, price of purchase;
      and
      (ii) the exchange, quotation system, or other facility through which the warrant
      purchase occurred. In addition, representatives of the Company and the Broker
      shall be made available (in person at the offices of the Commission in
      Washington, DC or by telephone) to respond to inquiries by the Commission
      regarding their purchase(s).

    
       

      Very
        truly yours,
