Interest on the Notes is payable semi-annually in arrears on, or nearest to, August 17 and February 17 in each year, beginning on August 17, 2017. The Notes are not rated. The holders of the Notes will have the right, at their option, to require the Company to repurchase for cash all of their Notes or any portion of the principal thereof that is equal to US$200,000 or integral multiples of US$1,000 in excess thereof on August 17, 2019.

The Company intends to use the Notes proceeds to refinance outstanding indebtedness, fund future capital needs, and for general corporate purposes.

The Company expects to close the offering of the Notes on or about October 11, 2017, subject to the satisfaction of customary closing conditions.

This press release shall not constitute an offer to sell or a solicitation of an offer to purchase any of the Notes, and shall not constitute an offer, solicitation or sale of the Notes in any state or jurisdiction in which such an offer, solicitation or sale would be unlawful. No public offering of the Notes will be made in the United States or to, or for the account or benefit of any U.S. person, and the Company does not intend to register any part of the offering in the United States.
