Re:

Management Rights

Gentlemen:

This letter will confirm our agreement that pursuant to and effective as of your purchase of Series B-I Shares of China Kanghui Holdings (the “Company”) pursuant to the Share Purchase Agreement dated as of April 21, 2009 among the parties thereof (the “Share Purchase Agreement”), VIVO Ventures Fund VI, L.P. and Vivo Ventures VI Affiliates Fund, L.P. (collectively, the “Investors”) shall be entitled to the following contractual management rights, in addition to any rights to non-public financial information, inspection rights and other rights specifically provided to the Investors in the Transaction Documents (as defined in the Share Purchase Agreement:

The Investors shall be entitled to consult with and advise management of the Company on significant business issues, including management’s proposed annual operating plans, and management will meet with the Investors regularly during each year at the Company’s facilities at mutually agreeable times for such consultation and advice and to review progress in achieving said plans.

The Investors may examine the books and records of the Company and inspect its facilities and may request information at reasonable times and intervals concerning the general status of the Company’s financial condition and operations, provided that access to highly confidential proprietary information and facilities need not be provided.

If the investors are not represented on the Company’s Board of Directors, the Company shall (1) invite the observer appointed by the Investors according to the Restated Memorandum and Articles (as defined in the Share Purchase Agreement) and to attend all meetings of its Board of Directors (and all committees thereof) in a nonvoting observer capacity, and (ii) give a representative of the Investors copies of al notices, minutes, consents and other material that the Company provides to its directors, except that the representative may be excluded from access to any material or meeting or portion thereof if the Company believes, upon advice of counsel, that such exclusion is reasonably necessary to preserve the attorney- client privilege, to protect highly confidential proprietary information or for other similar reasons. Upon reasonable notice and at a scheduled meeting of the Board or such other time, if any, as the Board may determine in its sole discretion, such representative may address the Board of Directors with respect to the Investors’ concerns regarding significant business issues facing the Company.

The aforementioned rights are intended to satisfy the requirement of management rights for purposes of qualifying the Investors’ ownership of stock in the Company as a “venture capita] investment” for purposes of the Department of Labor “plan asset” regulations, 29 C.F.R. §2510.3-101, and in the event the aforementioned rights are not satisfactory for such purpose, the Company and the Investor shall reasonably cooperate in good faith to agree upon mutually satisfactory management rights that satisfy such regulations.

The rights described herein shall terminate and be of no further force or effect upon (a) the consummation of the sale of the Company’s securities in connection with a firm- commitment underwritten initial public offering of the Common Shares of the Company on the New York Stock Exchange, the Nasdaq Stock Market’s National Market System, the Main Board of the Hong Kong Stock Exchange or any other exchange of the recognized international reputation and standing duly approved by the Company’s Board of Directors; or (b) the consummation of a merger or consolidation of the Company that is effected (1) for independent business reasons unrelated to extinguishing such rights and (ii) for purposes other than (A) the reincorporation of the Company in a different jurisdiction or (B) the formation of a holding company that will be owned exclusively by the Company’s stockholders and will hold all of the outstanding shares of capital stock of the Company’s successor.
