interests in the Exchanged Notes it beneficially owns, subject to this Agreement, that is inconsistent with the representations and warranties made in Section 4.4 above or that would render such Holder (and the beneficial
owners of the Exchanged Notes for which such Holder acts as investment advisor) otherwise unable to comply with its obligations under this Agreement. 

Section 4.6 Liens. The Exchanged Notes held by each Holder (or the beneficial owners of the Exchanged Notes
for which such Holder acts as investment advisor, as the case may be) are not subject to any lien, pledge, mortgage, security interest, charge, option or other encumbrance of adverse claim of any kind (a “Lien”), except for liens or

own account (or for the account of certain funds and/or accounts for which such Holder acts as investment advisor), for investment, and not with a view to or for sale in connection with any distribution thereof in violation of the registration
provisions of the Securities Act or the rules and regulations promulgated thereunder. Each Holder (and each beneficial owner of the Exchanged Notes for which such Holder acts as investment advisor) understands that the Second Lien Notes are being
issued to it in reliance on specific exemptions from the registration requirements of United States federal and state securities laws and that the Company is relying upon the truth and accuracy of, and each Holder’s compliance (and the
compliance of each beneficial owner of the Exchanged Notes for which such Holder acts as investment advisor) with, the representations, warranties, agreements, acknowledgments and understandings of such Holder (on its own behalf and on behalf of
each beneficial owner of the Exchanged Notes for which such Holder acts as investment advisor) set forth herein in order to determine the availability of such exemptions and the eligibility of such Holder (and each beneficial owner of the Exchanged
Notes for which such Holder acts as investment advisor) to acquire the Second Lien Notes. Each Holder (and each beneficial owner of the Exchanged Notes for which such Holder acts as investment advisor) acknowledges that no representations, express
or implied, are being made with respect to the Company, the Second Lien Notes, or otherwise, other than those expressly set forth herein. In making its decision to invest in the Second Lien Notes hereunder, such Holder has relied upon independent
investigations made by such Holder and, to the extent believed by such Holder to be appropriate, such Holder’s representatives, including such Holder’s own professional, tax and other advisors. Each Holder and its representatives have been
given the opportunity to ask questions of, and to receive answers from, the Company and its representatives concerning the terms and conditions of the investment in the Second Lien Notes. Each Holder has reviewed, or has had the opportunity to
review, all information it deems necessary and appropriate for such Holder to evaluate the financial risks inherent in an investment in the Second Lien Notes and has had sufficient time to evaluate the Exchange. Each Holder (and each beneficial
owner of the Exchanged Notes for which such Holder acts as investment advisor) understands that its investment in the Second Lien Notes involves a high degree of risk and that no Governmental Body has passed on or made any recommendation or
endorsement of the Second Lien Notes. 
 Section 4.9 Company Information. Each Holder understands and
acknowledges that (A) the Company has information that has not been publicly disclosed concerning the Company, 

  
 8 







 
its subsidiaries and affiliates, including, but not limited to, the general business, plans and prospects of the Company, its subsidiaries and affiliates as well as possible future financings and
other transactions or changes in the Company’s capital structure (the “Information”) and (B) such Information may be indicative of or affect the value of the Exchanged Notes or the Second Lien Notes. The Holder has not
requested to be provided with the Information, has not received the Information, and acknowledges that the Information might be material to its decision to enter into the Exchange or otherwise materially adverse to its interests. 

Section 4.10 Restricted Securities. Each Holder has been advised by the Company that (i) the offer and
sale of the Second Lien Notes has not been registered under the Securities Act; (ii) the offer and sale of the Second Lien Notes is intended to be exempt from registration under the Securities Act pursuant to Section 4(a)(2) under the
Securities Act; and (iii) there is currently no established market for the Second Lien Notes. Each Holder is familiar with Rule 144 promulgated by the Commission under the Securities Act, as presently in effect, and understands the resale
limitations imposed thereby and by the Securities Act. Each Holder (and each beneficial owner of the Exchanged Notes for which such Holder acts as investment advisor) will only sell or otherwise transfer the Second Lien Notes in accordance with the
Second Lien Notes Indenture. None of the Holders is an “affiliate” (as that term is defined in Rule 144(a)(1) under the Securities Act) of the Company or has been an “affiliate” of the Company during the preceding three
(3) months of the date hereof.

and the transactions contemplated hereby, other than Losses relating to (i) taxes, (ii) to the extent finally determined by a court of competent jurisdiction to have resulted from the bad faith, gross negligence or willful misconduct of such
Indemnified Holder, from a willful and material breach by a Holder of its obligations under this Agreement or from a claim solely among the Indemnified Holders or (iii) a claim brought by or on behalf of another holder of 2019 Notes or 2024

the Indemnified Holder promptly after receiving the aforesaid notice from such Indemnified Holder, to assume the defense thereof; provided, however, if the defendants in any such action include both the Indemnified Holder and the Company and the
Company or the Indemnified Holder shall have reasonably concluded that a conflict may arise between the positions of the Company and the Indemnified Holder in conducting the defense of any such action or that there may be legal defenses available to
them and/or other Indemnified Holders that are different from or additional to those available to the Company, the Indemnified Holder or Holders shall have the right to select separate counsel to assume such legal defenses and to otherwise
participate in the defense of such action on behalf of such Indemnified Holder or Holders. Upon receipt of notice from the Company to such Indemnified Holder of the Company’s election so to assume the defense of such action and approval by the
Indemnified Holder of counsel, the Company will not be liable to such 

  
 11 







 
Indemnified Holder for any legal or other expenses subsequently incurred by such Indemnified Holder in connection with the defense thereof unless (i) the Indemnified Holder shall have
employed separate counsel in accordance with the proviso to the preceding sentence (it being understood, however, that in connection with any such action the Company shall not be liable for the expenses of more than one separate counsel (in addition
to any local counsel) representing the Indemnified Holders who are parties to such action) or (ii) the Company shall not have employed counsel reasonably satisfactory to the Indemnified Holder to represent the Indemnified Holder within a
reasonable time after notice of commencement of the action. 
 (c) The Company shall not be liable for any settlement of any proceeding
effected without its written consent, which shall not be withheld unreasonably, but if settled with such consent or if there is a final judgment for the plaintiff, the Company agrees to indemnify the Indemnified Holder against any Loss by reason of
such settlement or judgment. The Company shall not, without the prior written consent of the Indemnified Holder, effect any settlement in any pending or threatened action, suit or proceeding in respect of which any Indemnified Holder is or could
have been a party and indemnity was or could have been sought hereunder by such Indemnified Holder, unless such settlement, compromise or consent (x) includes an unconditional release of such Indemnified Holder from all liability on claims that
are the subject matter of such action, suit or proceeding and (y) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any Indemnified Holder. 

(d) If the indemnification provided for in this Section 9.1 is for any reason unavailable to or otherwise
insufficient to hold harmless the Indemnified Holder in respect of any Loss referred to therein, then the Company shall contribute to the aggregate amount paid or payable by such Indemnified Holder, as incurred, as a result of any Loss referred to
therein: 
 (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one
hand, and the Holders, on the other hand, pursuant to this Agreement, or 
 (ii) if the allocation provided by
Section 9.1(d)(i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in Section 9.1(d)(i) above but also the relative fault of the Company, on
the one hand, and the Holders, on the other hand, as well as any other relevant equitable considerations. 
 The Company and each of the Holders agree that
it would not be just and equitable if contribution pursuant to this Section 9.1(d) were determined by pro rata allocation (even if the Holders were treated as one entity for such purpose) or by any other method of
allocation that does not take account of the equitable considerations referred to in this Section 9.1. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be
entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Holders’ obligations to contribute as provided in this Section 9.1(d) are several and not joint. 

(e) The provisions of this Section 9.1 will survive the Closing.
