Ladies and Gentlemen:

The undersigned, a holder of common stock, par value $0.001 per share (“Common Stock”), or rights to acquire Common Stock, of THT Heat Transfer Technology, Inc. (the “Company”) understands that you, as representative of the several Investors, propose to enter into a Securities Purchase Agreement (the “Purchase Agreement”) with the Company and certain other parties named therein, pursuant to which the Company will issue and sell in a private offering of Common Stock of the Company (the "Offering") to Investors. Capitalized terms used and not otherwise defined herein that are defined in the Purchase Agreement shall have the meanings given such terms in the Purchase Agreement.

In connection with the Offering, the Company has agreed to provide the Investors certain registration rights, and in furtherance thereof has agreed to file a registration statement to enable the Investors to resell certain of the securities subject of the Offering.

It is a condition to the Investors' respective obligations to close under the Purchase Agreement and provide the financing contemplating by the Offering that the Undersigned execute and deliver to the Investors this Lock-Up Agreement (“Agreement”).

In consideration of the Investors' agreement to enter into the Purchase Agreement and to proceed with the Offering of the Common Stocks, and for other good and valuable consideration receipt of which is hereby acknowledged, the undersigned hereby agree for the benefit of the Company, you and the other Investors to execute and deliver this Agreement.

NOW, THEREFORE, for and in consideration of the mutual covenants and agreements set forth herein, and other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the undersigned, intending to be legally bound, agree as follows:

1. Effectiveness of Agreement. This Agreement shall become null and void if the Purchase Agreement is terminated prior to its Closing as to all Investors.

From and after the date of this Agreement and until the second anniversary of the effective date of a registration statement resulting in all Shares being registered for resale by the Investors (plus one additional day for each Trading Day following the Effective Date of any Registration Statement during which either (1) the Registration Statement is not effective or (2) the prospectus forming a portion of the Registration Statement is not available for the resale of all Registrable Securities (as defined in the Registration Rights Agreement) required to be covered thereby) (the "Lockup Period"), the undersigned irrevocably agrees that, without the prior written consent of the Lead Investor, except as set forth below, it will not (A) offer, pledge, loan, encumber, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, voluntarily make any public announcement of a disposition offering or transfer, or otherwise transfer or dispose of, directly or indirectly, any of Holder’s Shares (including any securities convertible into, or exercisable or exchangeable for, or representing the rights to receive, Holder’s Shares) or engage in any Short Sales with respect to any security of the Company; or (B) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Common Stock, whether any such transaction described in clause (A) or (B) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise. The undersigned further agrees that it will not publicly disclose the intention to make any such offer, sale, pledge, redemption or disposition or to enter into any transaction described in the preceding sentence during the Lock-Up Period without, in each case, the prior written consent of the Lead Investor. In addition, the undersigned agrees that, without prior written consent of the Lead Investor, it will not, during the Lock-Up Period, make any demand for or exercise any right with respect to, the registration under the 1933 Act, of any Holder’s Shares or any security convertible into or exercisable or exchangeable for Holder’s Shares. In furtherance thereof, the Company will (x) place a stop order with the Transfer Agent on all Holder’s Shares, including those which are covered by a registration statement, (y) notify its Transfer Agent in writing of the stop order and the restrictions on such Holder’s Shares under this Agreement and direct the Transfer Agent not to process any attempts by the undersigned to resell or transfer any Holder’s Shares except in compliance with this Agreement. Notwithstanding the foregoing, the undersigned may transfer any of Holder's Shares by (a) bona fide gift or (b) will or intestate succession to his or her immediate family or to a trust the sole beneficiaries of which are one or more of the undersigned and his or her immediate family (the term "immediate family" meaning for these purposes the spouse, domestic partner, lineal descendant, father, mother or sibling of the undersigned), provided that (i) each resulting transferee of such Holder's Shares executes and delivers to the Lead Investor an agreement satisfactory to the certifying that such transferee is bound by the terms of this Agreement and has been in compliance with the terms hereof since the date first above written as if it had been an original party hereto and (ii) the undersigned notifies the Investors at least two (2) business days prior to the proposed transfer or disposition..

Furthermore, the undersigned recognizes that if it fails to perform, observe, or discharge any of its obligations under this Agreement, any remedy at law may prove to be inadequate relief to the Company or the Investors. Therefore, the undersigned agrees that each of the Company and the Investors shall be entitled to seek temporary and permanent injunctive relief in any such case without the necessity of proving actual damages and without posting a bond or other security.

14. Investors’ Reliance. The undersigned, whether or not participating in the Offering, understands that the Investors are entering into the Purchase Agreement and proceeding with the Offering in reliance upon this Agreement.

The arbitrator shall apply the law of the State of New York, United States of America, without regard for its principles of conflict of laws.

Judgment upon the award may be entered in any court having jurisdiction thereof. If either party shall commence a Proceeding to enforce any provisions of a Transaction Document, then the prevailing party in such Proceeding shall be reimbursed by the other party for its reasonable attorneys’ fees and other costs and expenses incurred with the investigation, preparation and prosecution of such Proceeding.
