The Notes bear interest at a fixed rate of 6.00% per year, payable semiannually in arrears on August 1 and February 1 of each year, beginning on August 1, 2013. The Notes are convertible into the Company’s common stock and may be settled as described below. The Notes will mature on February 1, 2018, unless earlier repurchased or converted. The Company may not redeem the Notes prior to maturity. The net proceeds from the Note Offering were approximately $119.4 million, after deducting discounts to the initial purchaser and estimated offering expenses payable by the Company. The Company intends to use the net proceeds of the offering to fund project related costs and capital expenditures and for general corporate purposes. The Notes are convertible at the option of the holders at any time prior to the close of business on the scheduled trading day immediately preceding February 1, 2018 into shares of the Company’s common stock at the then-applicable conversion rate. The conversion rate is initially 121.1240 shares of common stock per $1,000 principal amount of Notes (equivalent to an initial conversion price of approximately $8.26 per share of common stock). With respect to any conversion prior to November 1, 2016 (other than conversions in connection with certain fundamental changes where the Company may be required to increase the conversion rate as described below), in addition to the shares deliverable upon conversion, holders are entitled to receive an early conversion payment equal to $83.33 per $1,000 principal amount of Notes surrendered for conversion that may be settled, at the Company’s election, in cash or, subject to satisfaction of certain conditions, in shares of the Company’s common stock. The Company issued the Notes pursuant to an indenture dated as of January 24, 2013 (the “Indenture”) by and between the Company and Wells Fargo Bank, National Association, as trustee. The Indenture provides for customary events of default, including cross acceleration to certain other indebtedness of the Company and its significant subsidiaries. If the Company undergoes a fundamental change, holders may require the Company to repurchase for cash all or part of their Notes at a purchase price equal to 100% of the principal amount of the Notes to be repurchased, plus accrued and unpaid interest to, but excluding, the fundamental change repurchase date. In addition, if certain fundamental changes occur, the Company may be required in certain circumstances to increase the conversion rate for any Notes converted in connection with such fundamental changes by a specified number of shares of its common stock. The Notes are the general unsecured obligations of the Company and will be subordinated in right of payment to its Senior Debt. The Notes will effectively rank junior in right of payment to any of the Company’s secured indebtedness to the extent of the value of the assets securing such indebtedness and be structurally junior to all indebtedness and other liabilities of the Company’s subsidiaries, including trade payables. *Mitsui & Co., Ltd.
