is considered in a proceeding at law or in equity (the “Enforceability Exceptions”). This Agreement, each other Transaction Document to which the Holder is a party, and consummation of the Exchange and Purchase contemplated herein
and therein will not violate, conflict with or result in a breach of or default under (i) the Holder’s organizational documents, (ii) any agreement or instrument to which the Holder is a party or by which the Holder or any of its
assets are bound, or (iii) any laws, regulations or governmental or judicial decrees, injunctions or orders applicable to the Holder, except, in the case of clauses (ii) and (iii), as would not, individually or in the aggregate, be

Section 2.3 Title to the Exchanged Existing Notes. The Holder is the sole legal and beneficial owner of the
Exchanged Existing Notes and all rights and interests therein and thereto, and the Holder has good, valid and marketable title to the Exchanged Existing Notes, free and clear of any Liens (other than pledges or security interests that the Holder may

Section 2.4 Qualified Institutional Buyer. The Holder is a “qualified institutional buyer” within the

 Page 4 of 13









 
the Securities are “restricted securities” under applicable securities laws and that, pursuant to these laws and, therefore, cannot be sold, transferred, offered for sale, pledged,
hypothecated or otherwise disposed of unless they are subsequently registered and qualified under the Securities Act and applicable state laws or unless an exemption from such registration and qualification is available, and that evidence of the
Holder’s Securities will bear one or more legends to such effect and as otherwise required by the Indenture or the Warrant Agreement, as applicable (with the removal of any such legend governed by the terms of the Indenture or Warrant
Agreement, respectively), and (c) is acquiring the Holder’s Securities for investment purposes only, for the account of the Holder and not with any view toward a distribution thereof or with any intention of selling, distributing or
otherwise disposing of the Holder’s Securities in a manner that would violate the registration requirements of the Securities Act. The Holder is able to bear the economic risk of holding the Holder’s Securities for an indefinite period and
has sufficient knowledge and experience in financial and business matters so as to be capable of evaluating the merits and risks of its investment in the Holder’s Securities. The Indenture is not qualified under the Trust Indenture Act of 1939,

transactions in the securities of the Company (including, without limitation, any Short Sales (as defined below) involving any of the Company’s securities) since the time that such Holder was first contacted by either the Company, Cowen and
Company, LLC or any other person regarding an investment in the New Notes or the Company. Such Holder covenants that neither it nor any person acting on its behalf or pursuant to any understanding with such Holder will engage, directly or

defined in Rule 200 of Regulation SHO promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and all types of direct and indirect stock pledges, forward sale contracts, options, puts,
calls, short sales, swaps, derivatives and similar arrangements (including on a total return basis), and sales and other transactions through non-U.S. broker-dealers or foreign regulated brokers. Solely for purposes of this Section 2.7,
subject to the Holder’s compliance with its obligations under the U.S. federal securities laws and the Holder’s internal policies, “Holder” shall not be deemed to include any subsidiaries or affiliates of the Holder that are
effectively walled off by appropriate “Chinese Wall” information barriers approved by the Holder’s legal or compliance department (and thus have no knowledge of and have not been privy to any information concerning the Exchange and
Purchase). 
 Section 2.8 Adequate Information: No Reliance. The Holder acknowledges and agrees that
(a) the Holder has been furnished with all materials relating to the Company and the Exchange and Purchase that the Holder considers necessary or appropriate to making an investment decision to enter into the Exchange and Purchase and to invest

and prospects, and the terms and conditions of the Exchange and Purchase, (c) the Holder understands that its investment in the Securities involves a high degree of risk and has had the opportunity to consult with its accounting, tax, financial
and legal advisors to be able to evaluate the risks involved in the Exchange and Purchase and to make an informed investment decision with respect to the Exchange and Purchase and (d) the Holder has had such opportunity to obtain from
representatives of the Company such materials relating to the Company and the Exchange and Purchase as is necessary to permit it to evaluate the merits and risks of its investment in the Company and has independently, without reliance upon any
representatives of the Company and based on such materials relating to the Company and the Exchange and Purchase as the Holder deemed necessary and appropriate, made its own analysis and decision to enter into this Agreement and the other
Transaction Documents to which it is a party. 
 Section 2.9 No Public Market. The Holder understands that
no public market exists for the New Notes or Warrants, and that there is no assurance that a public market will ever develop for the New Notes or Warrants.

the Company and the Guarantors in connection with the execution, delivery or performance of the Transaction Documents and the consummation of the Exchange and Purchase have been obtained and will be effective as of the Closing Date, other than
(i) such filings required to be made after the Closing under applicable federal and state securities laws, (ii) filings required for the perfection of the security interests under the Collateral Documents and (iii) with respect to any
of the foregoing, where the failure to make or obtain would not reasonably be expected to have a material adverse effect on, or a material adverse change in, (A) the business, operations, financial condition, prospects or results of operations
of the Company and its subsidiaries, taken as a whole, or (B) the ability of the Company or the Guarantors to perform their obligations under this Agreement and the other Transaction Documents (other than any Other Agreements), as applicable (a
“Material Adverse Effect”). The entering into of the Transaction Documents (other than any Other Agreements) and the consummation of the Exchange and Purchase will not violate, conflict with or result in a breach of or default under

Securities. The Holder’s Securities have been duly authorized by the Company and, when executed and authenticated in accordance with the provisions of the Indenture, with respect to the New Notes, or the Warrant Agreement, with respect
to the Warrant, and delivered to the Holder pursuant to the Exchange and Purchase against delivery of the Exchanged Existing Notes and payment of the Purchase Price in accordance with the terms of this Agreement, the Holder’s Securities will be
valid and binding obligations of the Company, enforceable in accordance with their respective terms, except in each case that such enforcement may be subject to the Enforceability Exceptions. The issuance of the Holder’s Securities will not be
subject to any preemptive, participation, rights of first refusal and other similar rights. Assuming the accuracy of the Holder’s representations and warranties hereunder, the Holder’s Securities (i) will be issued in the Exchange and
