WHEREAS, the Pledgor has pledged in favor of the Secured Party 5,967,000 shares of common stock, par value US$0.0001 per share of Synutra International, Inc., a Delaware corporation (the “Common Stock”), in accordance with the Share Pledge Agreement;

WHEREAS, the parties desire to amend the Share Pledge Agreement to, among other things, reflect the Additional Pledged Stock as “Additional Pledged Stock” pursuant to Section 13.2 of the Share Pledge Agreement and further to provide that the parties shall not conduct an evaluation of the Collateral Value Amount (or make any corresponding adjustment to the amount of the Pledged Collateral) under Section 13.1 of the Share Pledge Agreement on April 30, 2009;

NOW, THEREFORE, the parties hereto agree as follows:

SECTION 1.  Unless otherwise specifically defined herein, all capitalized terms used but not defined herein shall have the meaning ascribed thereto under the Share Pledge Agreement. Each reference to “hereof”, “hereunder”, “herein” and “hereby” and each other similar reference and each reference to “this Agreement” and each other similar reference contained in the Share Pledge Agreement shall, upon effectiveness of this Amendment, refer to the Share Pledge Agreement as amended hereby.

SECTION 5. The Pledgor shall as soon as practical, at the expense of the Secured Party, make the necessary Uniform Commercial Code filings and register the charge created hereby in the register of registered charges kept by the Registrar for the Secured Party, in each case to perfect and register, as applicable, the Secured Party’s security interest and charges in the Additional Pledged Stock in the manner described in Section 7 of the Share Pledge Agreement.

SECTION 6. The first sentence of Section 13.1 of the Share Pledge Agreement is hereby amended and restated in its entirety as follows: “The parties shall calculate the Collateral Value Amount on October 31st and April 30th of each year during the term of the Note excluding April 30, 2009 (each an “Evaluation Date”).”

SECTION 7. All other terms of the Share Pledge Agreement shall remain in full force and effect in accordance with their respective terms.

SECTION 8. This Amendment shall be governed, construed and interpreted in accordance with the laws of the State of New York, without giving effect to principles of conflicts of law and choice of law that would cause the laws of any other jurisdiction to apply.

SECTION 9.  This Amendment may be executed in any number of counterparts and delivered by facsimile or email (or other reasonable means evidencing execution and delivery), each of which shall be deemed an original, but all of which shall together constitute one and the same instrument.
