“Exchange Offer”) for the Company’s 1.75% Convertible Senior Notes due 2021 (the “New Notes”) and the Company Payment Amount (as defined below) and (2) Existing Investors and other qualified new investors
(each, a “New Investor”) to subscribe for and purchase from the Company additional New Notes for cash (the “New Note Offering”), in each case, pursuant and subject to the terms and conditions set forth in this
Exchange/Subscription Agreement. As used herein, the term “Investor” refers to either an Existing Investor or a New Investor, as applicable. 

The Investor understands that the Exchange Offer and the New Note Offering are being made without registration under the Securities Act of
1933, as amended (the “Securities Act”), or any securities laws of any state of the United States or of any other jurisdiction, and that the Exchange Offer and the New Note Offering are only being made to Investors who are both

down to the nearest integral multiple of $1,000 in principal amount, if applicable (the difference being referred to as the “Rounded Amount”)) (such aggregate principal amount of New Notes, as so rounded, if applicable, the
“Exchanged New Notes”), and the Company hereby agrees to (a) issue such aggregate principal amount of Exchanged New Notes to the Existing Investor and (b) transfer an amount of cash set forth on Annex A hereto equal

and/or the New Note Offering and an investment in the New Notes. With the assistance of the Investor’s own professional advisors, to the extent that the Investor has deemed appropriate, the Investor has made its own legal, tax, accounting and
financial evaluation of the merits and risks of an investment in the New Notes and the consequences of the Exchange Offer and/or the New Note Offering and this Exchange/Subscription Agreement. The Investor has considered the suitability of the New
Notes as an investment in light of its own circumstances and financial condition, and the Investor is able to bear the risks associated with an investment in the New Notes. 







 (i) The Investor confirms that it is not relying on any communication (written or oral) of the
Company, J. Wood Capital Advisors LLC (the “Placement Agent”) or any of their respective agents or affiliates as investment advice or as a recommendation to participate in the Exchange Offer and/or the New Note Offering and receive
the New Notes pursuant to the terms hereof. It is understood that information provided in the Private Placement Documents, or by the Company, the Placement Agent or any of their respective agents or affiliates, shall not be considered investment
advice or a recommendation with respect to the Exchange Offer or the New Note Offering, and that none of the Company, the Placement Agent or any of their respective agents or affiliates is acting or has acted as an advisor to the Investor in
deciding whether to participate in the Exchange Offer or the New Note Offering. 
 (j) The Investor confirms that neither the Company nor
the Placement Agent has (1) given any guarantee or representation as to the potential success, return, effect or benefit (either legal, regulatory, tax, financial, accounting or otherwise) of an investment in the New Notes; or (2) made any
representation to the Investor regarding the legality of an investment in the New Notes under applicable investment guidelines, laws or regulations. In deciding to participate in the Exchange Offer and/or the New Note Offering, the Investor is not
relying on the advice or recommendations of the Company or the Placement Agent, and the Investor has made its own independent decision that the investment in the New Notes is suitable and appropriate for the Investor. 

(k) The Investor is familiar with the business and financial condition and operations of the Company and has conducted its own investigation
of the Company and the New Notes. The Investor has had access to the Company’s filings with the Securities and Exchange Commission and such other information concerning the Company and the New Notes as it deems necessary to enable it to make an
informed investment decision concerning the Exchange Offer and/or the New Note Offering. The Investor has been offered the opportunity to ask questions of the Company and its representatives and has received answers thereto as the Investor deems
necessary to enable it to make an informed investment decision concerning the Exchange Offer, the New Note Offering and the New Notes. 

(l) The Investor understands that no federal, state, local or foreign agency has passed upon the merits or risks of an investment in the New
Notes or made any finding or determination concerning the fairness or advisability of such investment.

“accredited investor” as defined in Rule 501(a) under the Securities Act and a “qualified institutional buyer” as defined in Rule 144A under the Securities Act. The Investor agrees to furnish any additional information reasonably

(n) The Investor is not directly, or indirectly through one or more intermediaries, controlling or controlled by, or under direct or indirect
common control with, the Company and is not, and has not been for the immediately preceding three months, an “affiliate” (within the meaning of Rule 144 under the Securities Act) of the Company. 

(o) The Investor is acquiring the New Notes solely for the Investor’s own beneficial account, or for an account with respect to which the
Investor exercises sole investment discretion, for investment purposes, and not with a view to, or for resale in connection with, any distribution of the New Notes. The Investor understands that the offer and sale of the New Notes have not been
registered under the Securities Act or any state securities laws by reason of specific exemptions under the provisions thereof that depend in part upon the investment intent of the Investor and the accuracy of the other representations made by the
Investor in this Exchange/Subscription Agreement. 
 (p) The Investor understands that the Company is relying upon the representations and
agreements contained in this Exchange/Subscription Agreement (and any supplemental information) for the purpose of 







 
determining whether the Investor’s participation in the Exchange Offer and/or the New Note Offering meets the requirements for such exemptions. In addition, the Investor acknowledges and
agrees that any hedging transactions engaged in by the Investor after the Transaction Information (as defined in the non-disclosure letter agreement entered into between the undersigned and the Placement Agent (the “Non-Disclosure
Agreement”)) is made public and prior to the Closing in connection with the issuance and sale of the New Notes have been and will be conducted in compliance with the Securities Act and the rules and regulations promulgated thereunder. 

(q) The Investor acknowledges that the Exchanged New Notes and the New Notes and the shares of Common Stock, if any, issuable upon conversion
thereof have not been registered under the Securities Act. As a result, the Exchanged New Notes and the New Notes and the shares of Common Stock, if any, issuable upon conversion thereof may not be offered or sold within the United States or to, or
for the account or benefit of, U.S. persons, except pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act as described under the heading “Transfer restrictions” in the
Private Placement Circular and the Investor hereby agrees that it will not sell the New Notes other than in compliance with such transfer restrictions. 

(r) The Investor acknowledges that the terms of the Exchange Offer and/or the New Notes Offering have been mutually negotiated between the
Investor and the Company. 
 (s) The Investor acknowledges the Company intends to pay the Placement Agent a fee in respect of the Exchange
Offer and the New Note Offering. 
 (t) The Investor will, upon request, execute and deliver any additional documents reasonably requested
by the Company, the Old Notes Trustee or the New Notes Trustee to complete the Exchange Offer and/or the purchase of New Notes. 
 (u) The
Investor understands that, unless the Investor notifies the Company in writing to the contrary before the Closing, each of the Investor’s representations and warranties contained in this Exchange/Subscription Agreement will be deemed to have
been reaffirmed and confirmed as of the Closing, taking into account all information received by the Investor. 
 (v) The Investor was given
a meaningful opportunity to negotiate the terms of the Exchange Offer. 
 (w) The Investor’s participation in the Exchange Offer and/or
the New Note Offering was not conditioned by the Company on the Investor’s exchange of a minimum principal amount of Exchanged Old Notes. 

(x) The Investor acknowledges that it had a sufficient amount of time to consider whether to participate in the Exchange Offer and/or the New
Note Offering and that neither the Company nor the Placement Agent has placed any pressure on the Investor to respond to the opportunity to participate in the Exchange Offer and/or the New Note Offering. 

7. Conditions to Obligations of the Investor and the Company. The obligations of the Investor to deliver the Exchanged Old Notes and the Cash Purchase
Price and of the Company to deliver the New Notes and to make payment of the Company Payment Amount are subject to the satisfaction at or prior to the Closing of the condition precedent that the representations and warranties of the Company and the
Investor contained in Sections 5 and 6, respectively, shall be true and correct as of the Closing in all material respects with the same effect as though such representations and warranties had been made as of the Closing. 

8. Covenant and Acknowledgment of the Company. At or prior to 5:00 p.m., New York City time, on the first business day after the date hereof, the
Company shall file a press release announcing the Exchange Offer and the New Note Offering on Form 8-K, which press release or Form 8-K the Company acknowledges and agrees will disclose all “Transaction Information” (as defined in the

if the Investor is not a United States person for U.S. federal income tax purposes, (1) the Company must be provided the appropriate IRS Form W-8 signed under penalties of perjury, attesting to that non-U.S. Investor’s foreign status, and
(2) the Investor may be subject to 30% U.S. federal withholding or 28% U.S. federal backup withholding tax on certain payments made to such Investor unless such Investor properly establishes an exemption from, or a reduced rate of, withholding
