Item8.01 Other Events.

On February17, 2017, the Company entered into separate privately
negotiated exchange agreements with certain holders of its 2.75%
Convertible SeniorNotesdue 2020 (the OldNotes) to exchange, in a
private placement in reliance on Section4(a)(2) and Regulation D
of the Securities Act, approximately $49.6million in aggregate
principal amount of OldNotes(the Exchange Transactions) for an
equal principal amount of the Companys 2.75% Convertible Exchange
SeniorNotesdue 2020 (the NewNotes).

The Company anticipates that the closings of the Exchange
Transactions will occur on or about February23, 2017.

Following the closings of the Exchange Transactions,
approximately $30.4million in aggregate principal amount of Old
Notes will remain outstanding.

The New Notes will be the Companys senior, unsecured obligations
and will rank senior in right of payment to any of the Companys
indebtedness that is expressly subordinated in right of payment
to the New Notes; equal in right of payment to any of the
Companys unsecured indebtedness that is not so subordinated,
including the Old Notes; effectively junior in right of payment
to any of the Companys secured indebtedness (including the
Companys existing 0% Convertible Senior Secured Notes due 2020
(the Secured Notes)) to the extent of the value of the assets
securing such indebtedness; and will be structurally junior to
all indebtedness and other liabilities (including trade payables)
of the Companys subsidiaries.

The New Notes bear interest at a fixed rate of 2.75%per year,
payable semiannually in arrears on June1 and December1 of each
year, beginning June1, 2017. Interest on the New Notes accrues
from December1, 2016. The New Notes will mature on December1,
2020, unless earlier repurchased, redeemed or converted.

The New Notes are convertible at any time prior to the close of
business on the business day immediately preceding the maturity
date, at the option of the holders, into (i)shares of the
Companys common stock (the Common Stock), plus (ii)a cash payment
equal to $150 for each $1,000 principal amount of New Notes
converted (the Additional Conversion Payment), subject to certain
adjustments. For conversions prior to September1, 2018 and the
Companys election to exercise its Mandatory Conversion Right (as
hereinafter defined), the Company will make an interest
make-whole payment to a converting holder for each $1,000
principal amount of New Notes being converted (the Interest
Make-Whole Payment). The Company may pay any Interest Make-Whole
Payment either in cash or in shares of Common Stock, at the
Companys election. If the Company elects to pay any Interest
Make-Whole Payment in cash it will pay cash in an amount equal to
the Interest Make-Whole Payment. If Company elects, or is deemed
to have elected, to pay any Interest Make-Whole Payment by
delivering shares of Common Stock, the number of shares of Common
Stock a converting holder of New Notes will receive for each
$1,000 principal amount of New Notes will be the number of shares
equal to the amount of the Interest Make-Whole Payment to be paid
to such holder, divided by the product of (x)98% and (y)the
simple average of the daily volume-weighted average price of the
Common Stock for the five trading days ending on and including
the trading day immediately preceding the conversion date.
Subject to compliance with certain conditions, the Company has
the right (the Mandatory Conversion Right) to, at its option,
mandatorily convert all of the New Notes if the daily
volume-weighted average price of the Common Stock is equal to or
greater than 60.0% of the applicable conversion price of the New
Notes for at least 20 Daily VWAP Trading Days (as defined in the
indenture governing the New Notes) (whether or not consecutive)
during any 30 consecutive Daily VWAP Trading Day period
(including the last trading day of such period).

The conversion rate is initially approximately 66.6667shares of
Common Stock per $1,000 principal amount of New Notes (equivalent
to an initial conversion price of $15.00 per share of Common
Stock), and will be subject to adjustment upon the occurrence of
certain events.

The Company may redeem for cash all or any portion of the New
Notes, at its option, on or after December1, 2019 at a redemption
price equal to 50% of the principal amount of the New Notes to be
redeemed, plus accrued and

unpaid interest to, but excluding, the redemption date. Upon a
fundamental change (as defined in the indenture governing the New
Notes), subject to certain exceptions, the holders of the New
Notes may require that the Company repurchase some or all of
their New Notes for cash at a repurchase price equal to 50% of
the principal amount of the New Notes being repurchased, plus any
accrued and unpaid interest to, but excluding, the fundamental
change repurchase date.

The events of default, which may result in the acceleration of
the maturity of the New Notes, include, among other things:

the Companys failure to pay any interest on the New Notes
when due and such failure continues for a period of 30 days
past the applicable due date;
the Companys failure to pay principal amount of the New Notes
when due and payable at maturity, upon declaration of
acceleration, upon any fundamental change purchase date, upon
any redemption date or otherwise;
the Companys failure to deliver the consideration due upon
the conversion of any New Notes (including the Additional
Conversion Payment and the Interest Make-Whole Payment, if
applicable) and such failure continues for five business
days;
the Companys failure to give a fundamental change notice when
due and such failure continues for a period of five days;
the Companys failure to comply with the Companys obligations
set forth in the indenture governing the New Notes relating
to certain consolidations, mergers and sales of assets;
the Companys failure to perform or observe any of the
Companys other covenants or warranties in the indenture
governing the New Notes or in the New Notes for 60 days after
written notice to the Company from the trustee or to the
Company and the trustee from the holders of at least 25% of
the aggregate principal amount of then outstanding New Notes
has been received by the Company;
default by the Company or any of the Companys significant
subsidiaries with respect to any mortgage, agreement or other
instrument under which there may be outstanding, or by which
there may be secured or evidenced, any indebtedness for money
borrowed in excess of $10.0 million in the aggregate of the
Company and/or any of the Companys subsidiaries, whether such
indebtedness now exists or shall hereafter be created
(i)resulting in such indebtedness becoming or being declared
due and payable or (ii)constituting a failure to pay the
principal or interest of any such debt when due and payable
at its stated maturity, upon required repurchase, upon
declaration or otherwise, and such acceleration shall not
have been rescinded or annulled or such failure to pay cured
within 30 days after written notice has been received by the
Company or such subsidiary from the trustee or by the
trustee, the Company and such subsidiary by the holders of at
least 25% in principal amount of the New Notes then
outstanding;
a final judgment for the payment of $10.0 million or more
(excluding any amounts covered by insurance) rendered against
the Company or any of the Companys significant subsidiaries,
which judgment is not discharged or stayed within 60 days
after (i)the date on which the right to appeal thereof has
expired if no such appeal has commenced, or (ii)the date on
which all rights to appeal have been extinguished; and
certain events of bankruptcy, insolvency and reorganization
of the Company or any of the Companys significant
subsidiaries.
