enforcing its rights under the Transaction Documents. The Company acknowledges that each of the Noteholders has been provided with the same Transaction Documents for the purpose of closing a transaction with multiple Noteholders and not because it
was required or requested to do so by any Noteholder.

authorized shares, obtain shareholder approval of an increase in such authorized number of shares, and voting the management shares of the Company in favor of an increase in the authorized shares of the Company to ensure that the number of
authorized shares is sufficient to provide for the conversion of all outstanding New Notes.

Section 6.6 Remedies Cumulative. Each Party acknowledges that the remedies at law of the other parties for a breach of this
Agreement would be inadequate and, in recognition of this fact, any party to this Agreement, without posting any bond or furnishing other security, and in addition to all other remedies that may be available, shall be entitled to equitable relief in
the form of specific performance, a temporary restraining order, a temporary or permanent injunction or any other equitable remedy that may then be available and no party shall oppose the granting of such relief on the basis that money damages would
be sufficient. Except as otherwise provided herein, all rights and remedies of the parties under this Agreement are cumulative and without prejudice to any other rights or remedies available at law; provided, however, that if a Party hereto has
exercised its remedies in connection with a purported event of default under the Indenture, such Party shall not be entitled to seek specific performance of any provisions of this Agreement. 

Section 6.7 Governing Law. All questions concerning the construction, validity, enforcement and interpretation of this Agreement
shall be governed by the internal laws of the State of New York, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of New York or any other jurisdictions) that would cause the application of the
laws of any jurisdictions other than the State of New York. Each Party hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in The City of New York, Borough of Manhattan, for the adjudication of any
dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein, and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject to
the jurisdiction of any such court, that such suit, action or proceeding is brought in an inconvenient forum or that the venue of such suit, action or proceeding is improper. Each Party hereby irrevocably waives personal service of process and
consents to process being served in any such suit, action or proceeding by mailing a copy thereof to such Party at the address for such notices to it under this Agreement and agrees that such service shall constitute good and sufficient service of
process and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any manner permitted by law. EACH PARTY HEREBY IRREVOCABLY WAIVES ANY RIGHT IT MAY HAVE, AND AGREES NOT TO REQUEST, A JURY TRIAL
FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR IN CONNECTION WITH OR ARISING OUT OF THIS AGREEMENT OR ANY TRANSACTION CONTEMPLATED HEREBY. 

Section 6.8 No Third Party Beneficiaries or Other Rights. Nothing herein shall grant to or create in any person not a party
hereto, or any such person’s dependents or heirs, any right to any benefits hereunder, and no such party shall be entitled to sue any Party to this Agreement with respect thereto. 

Section 6.9 Waiver; Consent. This Agreement may not be changed, amended, terminated, augmented, rescinded or discharged (other
than in accordance with its terms), in whole or in part, except by a writing executed by the Parties hereto. No waiver of any of the provisions or conditions of this Agreement or any of the rights of a Party hereto shall be effective or binding
unless such waiver shall be in writing and signed by the Party claimed to have given or consented thereto. Except to the extent 

  
 -11- 













 
otherwise agreed in writing, no waiver of any term, condition or other provision of this Agreement, or any breach thereof shall be deemed to be a waiver of any other term, condition or provision
or any breach thereof, or any subsequent breach of the same term, condition or provision, nor shall any forbearance to seek a remedy for any non-compliance or breach be deemed to be a waiver of a Party’s
rights and remedies with respect to such non-compliance or breach. 
 Section 6.10 Word
Meanings. The words such as “herein,” “hereinafter,” “hereof” and “hereunder” refer to this Agreement as a whole and not merely to a subdivision in which such words appear unless the context otherwise
requires. The singular shall include the plural, and vice versa, unless the context otherwise requires. The masculine shall include the feminine and neuter, and vice versa, unless the context otherwise requires. 

Section 6.11 Further Assurances. The Parties hereto each hereby agree to execute and deliver, or cause to be executed and
delivered, such other documents, instruments and agreements, and take such other actions, including giving any further assurances, as any Party may reasonably request in connection with the transactions contemplated by and in this Agreement. In
addition, subject to the terms and conditions set forth in this Agreement, each of the Parties shall use its reasonable best efforts (subject to, and in accordance with, applicable law) to take promptly, or to cause to be taken, all actions, and to
do promptly, or to cause to be done, and to assist and to cooperate with the other Parties in doing, all things necessary, proper or advisable under applicable laws to consummate and make effective the transactions contemplated hereby, including the
obtaining of all necessary, proper or advisable consents, approvals or waivers from third parties and the execution and delivery of any additional instruments reasonably necessary, proper or advisable to consummate the transactions contemplated
hereby. 
 Section 6.12 Headings. The headings in this Agreement are for convenience of reference only and shall not limit or
otherwise affect the meaning hereof. 
 Section 6.13 Severability. If any provision of this Agreement is prohibited by law or
otherwise determined to be invalid or unenforceable by a court of competent jurisdiction, the provision that would otherwise be prohibited, invalid or unenforceable shall be deemed amended to apply to the broadest extent that it would be valid and
enforceable, and the invalidity or unenforceability of such provision shall not affect the validity of the remaining provisions of this Agreement so long as this Agreement as so modified continues to express, without material change, the original
intentions of the parties as to the subject matter hereof and the prohibited nature, invalidity or unenforceability of the provision(s) in question does not substantially impair the respective expectations or reciprocal obligations of the parties or
the practical realization of the benefits that would otherwise be conferred upon the parties. The parties will endeavor in good faith negotiations to replace the prohibited, invalid or unenforceable provision(s) with a valid provision(s), the effect
of which comes as close as possible to that of the prohibited, invalid or unenforceable provision(s). 
 Section 6.14 Tax
Treatment. 
 (a) The Parties agree (i) that for U.S. federal and other applicable income tax purposes, exchange of a Note for a New
Note, pursuant to the terms of this Agreement, is an exchange, for purposes of applying Section 1.1001-1(a) of the United States Treasury Regulations, of each such Note pursuant to Section 1.1001-3 of the United States Treasury Regulations, (ii) that the New Notes are part of the same issue pursuant to Section 1.1275-1(f) of the United
States Treasury Regulations, (iii) that the issue price of the New Notes shall be determined in accordance with the applicable provisions of Section 1.1273-2 of the United States Treasury
Regulations, and (iv) to file all U.S. federal income tax and state income tax and franchise tax returns, as applicable, in a manner consistent with the foregoing unless otherwise required pursuant to a final “determination” under
Section 1313(a) of the Code. . 

  
 -12- 













 (b) The Parties agree that the Company will not withhold any income tax from any
consideration transferred in the Exchange to a Noteholder, subject to receipt by the Company, from such Noteholder, of the documentation set forth in Section 1.3(b). 

Section 6.15 Survival of Representations. The representations, warranties, covenants and agreements of the Company and each of the
Noteholders contained in this Agreement or in any certificate furnished hereunder shall survive the Closing.  
 Section 6.16
Expenses. The Company shall be responsible for the payment of any agent’s fees, financial advisory fees, or broker’s commissions (other than for persons engaged by any Noteholder) relating to or arising out of the transactions
contemplated hereby. The Company shall pay, and hold the Noteholders harmless against, any liability, loss or expense (including, without limitation, reasonable attorney’s fees and
out-of-pocket expenses) arising in connection with any claim relating to any such payment. Except as otherwise set forth in this Agreement, the New Indentures and any
other document contemplated hereby and thereby, each party to this Agreement shall bear its own expenses in connection with the Exchange.  

Section 6.17 Indemnification. In consideration of each Noteholder’s execution and delivery of this Agreement and acquiring
the New Notes thereunder and in addition to all of the Company’s other obligations under the Transaction Documents, and subject to the Subordination Agreement, the Company shall defend, protect, indemnify and hold harmless each Noteholder and
each other holder of the New Notes and all of their stockholders, partners, members, officers, directors, employees and direct or indirect investors and any of the foregoing persons’ agents or other representatives (including, without
limitation, those retained in connection with the transactions contemplated by this Agreement) (collectively, the “Indemnitees”) from and against any and all actions, causes of action, suits, claims, losses, costs, penalties, fees,
liabilities and damages, and expenses in connection therewith (irrespective of whether any such Indemnitee is a party to the action for which indemnification hereunder is sought), and including reasonable attorneys’ fees and disbursements (the
“Indemnified Liabilities”), incurred by any Indemnitee as a result of, or arising out of, or relating to (a) any misrepresentation or breach of any representation or warranty made by the Company in the Transaction Documents or
any other certificate, instrument or document contemplated hereby or thereby, (b) any breach of any covenant, agreement or obligation of the Company contained in the Transaction Documents or any other certificate, instrument or document
contemplated hereby or thereby or (c) any cause of action, suit, or claim brought or made against such Indemnitee by a third party (including for these purposes a derivative action brought on behalf of the Company) and arising out of or
resulting from (i) the execution, delivery, performance or enforcement of the Transaction Documents or any other certificate, instrument or document contemplated hereby or thereby, (ii) any transaction financed or to be financed in whole
or in part, directly or indirectly, with the proceeds of the issuance of the New Notes, or (iii) the status of such Noteholder or holder of the New Notes as an investor in the Company pursuant to the transactions contemplated by Transaction
Documents and the transactions contemplated hereby and thereby; in each of the foregoing cases other than Indemnified Liabilities (x) resulting from a claim solely among the Indemnitees, and (y) to the extent finally determined by a court
of competent jurisdiction to have resulted from (i) the bad faith, gross negligence or willful misconduct of such Indemnitees, or (ii) a breach by a Noteholder of its obligations under this Agreement. To the extent that the foregoing
undertaking by the Company may be unenforceable for any reason, the Company shall make the maximum contribution to the payment and satisfaction of each of the Indemnified Liabilities that is permissible under applicable law. 

Section 6.18 Indemnification Procedures. Promptly after receipt by an Indemnitee of notice of the commencement of any action, such
indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under Section 6.17, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party
(i) will not relieve it from 

  
 -13- 













 
liability under Section 6.17 unless and to the extent such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any
event, relieve the indemnifying party from any obligations to any Indemnitee other than the indemnification obligation provided in Section 6.17. The indemnifying party shall be entitled to appoint counsel of the indemnifying party’s choice
at the indemnifying party’s expense to represent the Indemnitee in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel,
retained by the Indemnitee or parties except as set forth below); provided, however, that such counsel shall be reasonably satisfactory to the Indemnitee. Notwithstanding the indemnifying party’s election to appoint counsel to represent the
Indemnitee in an action, the Indemnitee shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel
chosen by the indemnifying party to represent the Indemnitee would present such counsel with a conflict of interest; (ii) the actual or potential defendants in, or targets of, any such action include both the Indemnitee and the indemnifying
party and the Indemnitee shall have reasonably concluded that there may be legal defenses available to it and/or other Indemnitees that are different from or additional to those available to the indemnifying party; (iii) the indemnifying party
shall not have employed counsel reasonably satisfactory to the Indemnitee to represent the Indemnitee within a reasonable time after notice of the institution of such action; or (iv) the indemnifying party shall authorize the Indemnitee in
writing to employ separate counsel at the expense of the indemnifying party. An indemnifying party will not, without the prior written consent of the Indemnitees, settle or compromise or consent to the entry of any judgment with respect to any
pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the Indemnitees are actual or potential parties to such claim or action) unless such settlement,
compromise or consent includes an unconditional release of each Indemnitee from all liability arising out of such claim, action, suit or proceeding.
