The Company expects that the issuance of the additional Exchange Notes in the Exchange Transactions will close on March 15, 2018, subject to satisfaction of customary closing conditions, and will be issued pursuant to the Second Supplemental Indenture, dated March 6, 2018 (the “Second Supplemental Indenture”) to the Indenture, dated February 4, 2014, between the Company and U.S. Bank National Association (the “Base Indenture” and, together with the Second Supplemental Indenture, the “Indenture”).

The Exchange Notes will have an interest rate of 2.75% per year per $1,000, which will accrue on the principal amount of Exchange Notes, payable in cash semi-annually in arrears on February 1 and August 1 of each year, beginning August 1, 2018, and will mature on February 1, 2034, unless earlier repurchased, redeemed or converted.  Interest on the Exchange Notes will accrue from February 1, 2018.

The Exchange Notes will have an initial conversion rate of 126.9438 shares of the Company’s common stock, par value $0.001 per share (“Common Stock”), per $1,000 principal amount, subject to adjustment, and will be convertible into cash, shares of the Company’s Common Stock or any combination of cash and shares of the Company’s Common Stock, at the Company’s election.  The Exchange Notes will be convertible at the option of the holder at any time prior to the business day immediately preceding the maturity date for the Exchange Notes.  The Exchange Notes will also be convertible at the Company’s option upon certain conditions specified in the Indenture (the “issuer’s conversion option”).

In the event of a “fundamental change” (as defined in the Indenture), holders of the Exchange Notes may require the Company to repurchase all or a portion of their Exchange Notes at a repurchase price equal to 100% of the accreted principal amount of the Exchange Notes, plus accrued and unpaid interest, if any, to, but excluding, the repurchase date.  Holders who convert their Exchange Notes voluntarily prior to the exercise of the Company’s issuer conversion option or in connection with a make-whole fundamental change prior to February 6, 2023 will, under, certain circumstances, be entitled to a make-whole premium in the form of an increase in the conversion rate determined by reference to a make-whole table set forth in the Indenture.

Holders of the Exchange Notes will have the right, at their option, to require the Company to purchase their Exchange Notes (i) on February 6, 2023, February 6, 2026 and February 6, 2029 or (ii) if the Company undergoes a fundamental change (as defined in the Indenture), in each case, at a repurchase price equal to 100% of the accreted principal amount of the Exchange Notes on the fundamental change repurchase date, plus accrued and unpaid interest, if any, to, but excluding the repurchase date.

On or after February 6, 2022, the Company may elect to redeem all or any portion of the Exchange Notes at a redemption price equal to 100% of the accreted principal amount of the Exchange Notes on the redemption date of the Exchange Notes, plus accrued and unpaid interest, if any, to, but excluding the redemption date.

The Exchange Notes will be the Company’s senior unsecured obligations and will rank senior in right of payment to any of the Company’s indebtedness that is expressly subordinated in right of payment to the Exchange Notes, will rank equally in right of payment with any of the Company’s unsecured indebtedness that is not so subordinated, will be effectively 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 will be structurally subordinated to all indebtedness and other liabilities of the Company’s subsidiaries.

Each of the following events is considered an “event of default” with respect to the Exchange Notes, which may result in the acceleration of the accreted principal amount for the Exchange Notes in accordance with the provisions of the Indenture:

• the Company’s failure to pay the accreted principal amount of the Exchange Notes or the repurchase price or redemption price for any Exchange Note when due;
• the Company’s failure to deliver the settlement amount upon conversion of any Exchange Note when due, which failure continues for five business days;
• the Company’s failure to pay any interest on any Exchange Note when due, and such failure continues for 30 days;
• the Company’s failure to provide timely notice of a fundamental change or a make-whole fundamental change in accordance with the terms of the Indenture;
• the Company’s failure to perform any other covenants required of it under the Indenture, and such failure continues for 60 calendar days after notice is given in accordance with the Indenture;
•  the Company’s failure, or the failure of any of its significant subsidiaries (as defined in Regulation S-X under the Securities Act) to pay at maturity any Indebtedness (as defined in the Indenture) in a principal amount in excess of $15 million, or the acceleration of Indebtedness of the Company or any of its significant subsidiaries in an amount in excess of $15 million (unless such Indebtedness is discharged or such acceleration has been cured, waived, rescinded or annulled, in either case, within a period of 30 days after written notice is provided to the Company in accordance with the Indenture); and
• certain events of bankruptcy, insolvency or reorganization with respect to the Company or any of its significant subsidiaries.
