(1)	Interest is payable semi-annually on each of the series of senior and convertible senior notes. The annual effective interest rate is calculated after giving effect to the amortization of the deferred financing costs and any discount or premium associated with the note issuance.
(2)	The Company may redeem the notes in whole at any time or in part from time to time, at a redemption price equal to the greater of 100% of their principal amount or the present value of the remaining scheduled payments on the redemption date, plus in each case, accrued interest.
(3)	Holders of the 2% convertible senior notes may convert all or any portion of their notes at their option at any time prior to maturity. The initial conversion rate for the notes is 76.5697 shares of the Company’s common stock per $1,000 principal amount of senior notes, equivalent to an initial conversion price of approximately $13.06 per share of common stock. The conversion rate is subject to adjustment in certain events but will not be adjusted for accrued interest, including any additional interest. Upon conversion of a 2% senior note, the Company will pay or deliver, as the case may be, cash, shares of its common stock or a combination thereof at its election. The Company may not redeem the notes prior to the maturity date.
