Dear Mr. Kraus:

 

Reference is made to that certain underwriting
agreement between Blue Wolf Mongolia Holdings Corp. (the “Company”) and Deutsche Bank Securities Inc., as the
representative of the Underwriters (“Deutsche Bank”) dated July 14, 2011 (the “Underwriting
Agreement”). Defined terms used but not defined herein shall have the meaning ascribed to them in the Underwriting Agreement.

 

Pursuant to Section 2(a) of the Underwriting
Agreement, the Company has previously deposited $0.30 per Unit sold in the Company’s initial public offering (for a total
of $2,415,000) in the Trust Account as a deferred underwriting discount, which amount is payable to the Underwriters upon the consummation
by the Company of an initial business combination (the “Business Combination”) with one or more assets or operating
businesses, through a merger, capital stock exchange, purchase, asset acquisition, exchangeable share transaction, stock or asset
purchase or other similar business combination (the “Original Fee”).

 

This letter agreement (the “Agreement”)
confirms the agreement between the parties that the Underwriters will receive upon the closing of the Business Combination, in
lieu of the Original Fee, an amount equal to the sum of: (i) $1,000,000 and (ii) (a) $1,400,000, multiplied by (b) the quotient
of: (x) the amount of cash remaining in the Trust Account at the closing of the Business Combination after payment of the aggregate
Redemption Price to holders of Ordinary Shares that have tendered such shares to the Company, divided by (y) $80,237,500 (the “Revised
Fee”).

 

Each of the Underwriters hereby irrevocably
agrees, acknowledges, waives and releases, as the case may be, on behalf of itself and on behalf of each of their respective representatives,
agents, attorneys, employees, predecessors, successors, permitted assigns and all persons acting by, through or in concert with
them in connection with the Company’s initial public offering, any right to receive from the Company the difference between
the Original Fee and the Revised Fee.

 

Except as set forth herein, the terms and
conditions of the existing Underwriting Agreement shall remain in full force and effect.
