STOCK ESCROW AGREEMENT

STOCK ESCROW AGREEMENT, dated as of                             , 2007 (“Agreement”) by and among Stone Tan China Acquisition Corp., a Delaware corporation (“Company”), the undersigned parties listed as Initial Stockholders on the signature page hereto (collectively, the “Initial Stockholders”) and Continental Stock Transfer & Trust Company, a New York corporation (“Escrow Agent”).

WHEREAS, the Company has entered into an Underwriting Agreement, dated                 , 2007 (“Underwriting Agreement”) with Morgan Joseph & Co., Inc. (“Morgan Joseph”), as representative of the underwriters named therein (collectively, “Underwriters”), pursuant to which, among other matters, the Underwriters have agreed to purchase 12,500,000 units (“Units”) of the Company. Each Unit consists of one share of the Company’s common stock, par value $.0001 per share (“Common Stock”), and one warrant, each warrant to purchase one share of Common Stock, all as more fully described in the Company’s definitive Prospectus, dated                     , 2007 (“Prospectus”) comprising part of the Company’s Registration Statement on Form S-1 (File No. 333-                  ) under the Securities Act of 1933, as amended (“Registration Statement”), declared effective on                             , 2007 (“Effective Date”); and

WHEREAS, the Initial Stockholders have agreed, as a condition of the Underwriters’ obligation to purchase the Units pursuant to the Underwriting Agreement and to offer them to the public, to deposit all of their shares of Common Stock as set forth opposite their respective names in Schedule A attached hereto (collectively “Escrow Shares”), in escrow as hereinafter provided; and

WHEREAS, the Company and the Initial Stockholders desire that the Escrow Agent accept the Escrow Shares, in escrow, to be held and disbursed as hereinafter provided.

NOW, THEREFORE, IT IS AGREED:

1.             Appointment of Escrow Agent. The Company and the Initial Stockholders hereby appoint the Escrow Agent to act in accordance with and subject to the terms of this Agreement and the Escrow Agent hereby accepts such appointment and agrees to act in accordance with and subject to such terms.

2.             Deposit of Escrow Shares. With respect to the Escrow Shares, each of the Initial Stockholders shall deliver on or prior to the Effective Date to the Escrow Agent certificates representing his or her respective Escrow Shares that have been issued as of such date, to be held and disbursed subject to the terms and conditions of this Agreement. Each Initial Stockholder acknowledges and agrees that the certificates representing his or her Escrow Shares is legended to reflect the deposit of such Escrow Shares under this Agreement.

3.             Disbursement of the Escrow Shares. The Escrow Agent shall hold the Escrow Shares until one year from the closing date of a Business Combination (“Escrow Period”), on which date it shall, upon written instructions from each Initial Stockholder, disburse each of the Initial Stockholder’s Escrow Shares to such Initial Stockholder; provided, however, that if the Underwriters do not exercise their over-allotment option in full, up to 468,750 of Escrow Shares shall be released to the Company upon written instruction from the Company; provided, further, that if the Escrow Agent is notified by the Company pursuant to Section 6.6 hereof that the Company is being liquidated at any time during the Escrow Period, then the Escrow Agent shall promptly destroy the certificates representing the Escrow Shares; provided further, that if, after the Company consummates a Business Combination, it (or the surviving entity) subsequently consummates a liquidation, merger, stock exchange or other similar transaction which results in all of its stockholders of such entity having the right to exchange their shares of Common Stock for cash, securities or other property, then the Escrow Agent will, upon receipt of a certificate, executed by the Chairman, Chief Executive Officer or Chief Financial Officer of the Company, in form reasonably acceptable to the Escrow Agent, that such transaction is then being consummated, release the Escrow Shares to the Initial Stockholders upon consummation of such transaction so that they can similarly participate. Upon written instructions from the Company advising that a Business Combination has been consummated and that public stockholders holding in excess of 20% of the shares of Common Stock issued pursuant to the Registration Statement exercise the right to redeem their shares for cash as described in the Registration Statement, the Escrow Agent will release and deliver to the Company for cancellation on a pro rata basis certificates representing that number of Escrow Shares (up to a maximum of 390,625) which results in the Initial Stockholders collectively owning no more then 23.81% of the Company’s outstanding Common Stock immediately prior to the consummation of the Business Combination after giving effect to the redemption. Such instructions shall be set forth both the number of shares the Company is redeeming and the number of Escrow Shares to be delivered to the Company for cancellation. The Escrow Agent shall have no further duties hereunder after the disbursement or destruction of the Escrow Shares in accordance with this Section 3.

4.             Rights of Initial Stockholders in Escrow Shares.

4.1           Voting Rights as a Stockholder. Subject to the terms of the Insider Letter described in Section 4.4 hereof and except as herein provided, the Initial Stockholders shall retain all of their rights as stockholders of the Company during the Escrow Period, including, without limitation, the right to vote such shares.

4.2           Dividends and Other Distributions in Respect of the Escrow Shares. During the Escrow Period, all dividends payable in cash with respect to the Escrow Shares shall be paid to the Initial Stockholders, but all dividends payable in stock or other non-cash property (“Non-Cash Dividends”) shall be delivered to the Escrow Agent to hold in accordance with the terms hereof. As used herein, the term “Escrow Shares” shall be deemed to include the Non-Cash Dividends distributed thereon, if any.

4.3           Restrictions on Transfer. During the Escrow Period, no sale, transfer or other disposition may be made of any or all of the Escrow Shares except (i) by gift to a member of Initial Stockholder’s immediate family or to a trust or other entity, the beneficiary of which is an Initial Stockholder or a member of an Initial Stockholder’s immediate family, or (ii) by virtue of the laws of descent and distribution upon death of any Initial Stockholder, (iii) pursuant to a qualified domestic relations order; provided, however, that such permissive transfers may be implemented only upon the respective transferee’s written agreement to be bound by the terms and conditions of this Agreement and of the Insider Letter signed by the Initial Stockholder transferring the Escrow Shares. During the Escrow Period, the Initial Stockholders shall not pledge or grant a security interest in the Escrow Shares or grant a security interest in their rights under this Agreement.

5.             Concerning the Escrow Agent.

5.1           Good Faith Reliance.

The Escrow Agent shall not be bound by any notice or demand, or any waiver, modification, termination or rescission of this Agreement unless evidenced by a writing delivered to the Escrow Agent signed by the proper party or parties and, if the duties or rights of the Escrow Agent are affected, unless it shall have given its prior written consent thereto.

5.2           Indemnification. The Escrow Agent shall be indemnified and held harmless by the Company from and against any expenses, including counsel fees and disbursements, or loss suffered by the Escrow Agent in connection with any action, suit or other proceeding involving any claim which in any way, directly or indirectly, arises out of or relates to this Agreement, the services of the Escrow Agent hereunder, or the Escrow Shares held by it hereunder, other than expenses or losses arising from the gross negligence or willful misconduct of the Escrow Agent. Promptly after the receipt by the Escrow Agent of notice of any demand or claim or the commencement of any action, suit or proceeding, the Escrow Agent shall notify the other parties hereto in writing. In the event of the receipt of such notice, the Escrow Agent, in its sole discretion, may commence an action in the nature of interpleader in an appropriate court to determine ownership or disposition of the Escrow Shares or it may deposit the Escrow Shares with

the clerk of any appropriate court or it may retain the Escrow Shares pending receipt of a final, non appealable order of a court having jurisdiction over all of the parties hereto directing to whom and under what circumstances the Escrow Shares are to be disbursed and delivered. The provisions of this Section 5.2 shall survive in the event the Escrow Agent resigns or is discharged pursuant to Sections 5.5 or 5.6 below.

5.3           Compensation. The Escrow Agent shall be entitled to reasonable compensation from the Company for all services rendered by it hereunder, as set forth on Exhibit A hereto. The Escrow Agent shall also be entitled to reimbursement from the Company for all expenses paid or incurred by it in the administration of its duties hereunder including, but not limited to, all counsel, advisors’ and agents’ fees and disbursements and all taxes or other governmental charges. The Escrow Agent shall bill the Company on a monthly basis for services rendered.

5.4           Further Assurances. From time to time on and after the date hereof, the Company and the Initial Stockholders shall deliver or cause to be delivered to the Escrow Agent such further documents and instruments and shall do or cause to be done such further acts as the Escrow Agent shall reasonably request to carry out more effectively the provisions and purposes of this Agreement, to evidence compliance herewith or to assure itself that it is protected in acting hereunder.

5.5           Resignation. The Escrow Agent may resign at any time and be discharged from its duties as escrow agent hereunder by its giving the other parties hereto written notice and such resignation shall become effective as hereinafter provided. Such resignation shall become effective at such time that the Escrow Agent shall turn over to a successor escrow agent appointed by the Company and approved by Morgan Joseph, the Escrow Shares held hereunder. If no new escrow agent is so appointed within the 60 day period following the giving of such notice of resignation, the Escrow Agent may deposit the Escrow Shares with any court it deems appropriate.

5.6           Discharge of Escrow Agent. The Escrow Agent shall resign and be discharged from its duties as escrow agent hereunder if so requested in writing at any time by the Company and a majority of the Initial Stockholders, jointly, provided, however, that such resignation shall become effective only upon acceptance of appointment by a successor escrow agent as provided in Section 5.5.
