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 90^th 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 Xxxxx; 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,

Xxxx-Xxxx Xxx
