Underwriting Agreement

On September 24, 2014, the Company entered into an underwriting agreement with Morgan Stanley & Co. LLC and UBS Securities LLC, as representatives of the several underwriters listed in Schedule I thereto relating to the sale of the Common Shares in the IPO (the “Underwriting Agreement”).

The Underwriting Agreement has been included as an exhibit to this Current Report on Form 8-K to provide you with information regarding its terms. The Underwriting Agreement contains representations and warranties that the parties thereto made to the other parties thereto as of specific dates. The assertions embodied in the representations and warranties in the Underwriting Agreement were made solely for purposes of the contract among the respective parties, and each may be subject to important qualifications and limitations agreed to by the parties in connection with negotiating the terms thereof. Moreover, some of those representations and warranties may not be accurate or complete as of any specified date, may be subject to a contractual standard of materiality different from those generally applicable to shareholders or may have been used for the purpose of allocating risk among the parties rather than establishing matters as facts.

The Underwriting Agreement is attached hereto as Exhibit 1.1 and incorporated herein by reference.
