Section 8.6Headings; Construction.

Unless the context clearly indicates otherwise, each pronoun herein shall be deemed to include the masculine, feminine, neuter, singular and plural forms thereof. The terms “including,” “includes,” “include” and words of like import shall be construed broadly as if followed by the words “without limitation.” The terms “herein,” “hereunder,” “hereof” and words of like import refer to this entire Agreement instead of just the provision in which they are found. The parties agree that each of them and their respective counsel has reviewed and had an opportunity to revise this Agreement and, therefore, the normal rule of construction to the effect that any ambiguities are to be resolved against the drafting party shall not be employed in the interpretation of this Agreement. Any reference in this Agreement to “Dollars” or “$” shall mean the lawful currency of the United States of America.

Section 8.7Successors and Assigns. Each Investor may assign its rights or obligations pursuant to this Agreement to any of its Affiliates, subject to such assignee Affiliate making the representations and warranties set forth in Article III as of the date of such Transfer.

The assignment by a party to this Agreement of any rights hereunder shall not affect the obligations of such party under this Agreement.

This Agreement shall be governed by and construed in accordance with the internal procedural and substantive laws of the State of New York, without giving effect to the choice of law provisions of such state that would cause the application of the laws of any other jurisdiction.

Section 8.9Counterparts. This Agreement may be executed in counterparts, all of which taken together shall constitute one and the same original and binding instrument and shall become effective when all counterparts have been signed by each party and delivered to the other parties hereto, it being understood that all parties hereto need not sign the same counterpart. In the event any signature is delivered by digital or electronic transmission, such transmission shall constitute delivery of the manually executed original.

[***] = Certain information has been excluded from this exhibit because it is both not material and would likely cause competitive harm to the company if publicly disclosed.

Section 8.10Severability. The provisions of this Agreement are severable and, in the event that any court of competent jurisdiction shall determine that any one or more of the provisions or part of the provisions contained in this Agreement shall, for any reason, be held to be invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other provision or part of a provision of this Agreement, and this Agreement shall be reformed and construed as if such invalid or illegal or unenforceable provision, or part of such provision, had never been contained herein, so that such provisions would be valid, legal and enforceable to the maximum extent possible.

Section 8.11No Third Party Beneficiaries.This Agreement is intended only for the benefit of the parties hereto and their respective permitted successors and assigns, and is not for the benefit of, nor may any provision hereof be enforced by, any other Person.

Section 8.14Termination. This Agreement may be terminated at any time prior to the Closing: (a) by mutual written consent of the Company and the Investors representing a majority of the aggregate Commitment; (b) by written notice from either the Company or the Investors representing a majority of the Notes, if any Governmental Authority with lawful jurisdiction shall have issued a final order, decree or ruling or taken any other final action restraining, enjoining or otherwise prohibiting the transactions contemplated by the Transaction Documents and such order, decree, ruling or other action is or shall have become final and nonappealable; (c) by written notice from either the Company or the Investors representing a majority of the Notes, if the Closing does not occur by 11:59 p.m. New York City time on the End Date;provided, however, that the right to terminate this Agreement pursuant to thisSection 8.14(c) shall not be available to any Party whose failure to fulfill any obligations under this Agreement shall have been the cause of, or shall have resulted in, the failure of the Closing to occur on or prior to such date; (d) by notice given from the Company, if there have been one or more inaccuracies in or breaches of one or more representations, warranties, covenants or agreements made by the Investors in this Agreement such that the conditions inSection 7.2(iii) would not be satisfied and which have not been cured by the Investors five Business Days after receipt by the Investors of written notice from the Company requesting such inaccuracies or breaches to be cured; (e) by notice given by the Investors representing a majority of the aggregate Commitment, if there have been one or more inaccuracies in or breaches of one or more representations, warranties, covenants or agreements made by the Company in this Agreement such that the conditions inSection 7.1(i) would not be satisfied and which have not been cured by the Company within five Business Days after receipt by the Company of written notice from the Investors requesting such inaccuracies or breaches to be cured.

ARTICLE X

INDEMNIFICATION

Section 10.1Indemnification by the Company. The Company agrees to indemnify each Investor and Option Party and the respective directors, officers, advisors, agents and employees of each such Investor and Option Party (collectively, “Investor Related Parties”) from costs, losses, liabilities, damages, or expenses of any kind or nature whatsoever, and hold each of them harmless against, any and all actions, suits, proceedings (including any investigations, litigation or inquiries), demands, and causes of action, and, in connection therewith, and promptly upon demand, pay or reimburse each of them for all costs, losses, liabilities, damages, or expenses of any kind or nature whatsoever, including, without limitation, the reasonable fees and disbursements of counsel and all other reasonable expenses incurred in connection with investigating, defending or preparing to defend any such matter that may be incurred by them or asserted against or involve any of them as a result of, or arising out of, a breach of a representation or warranty by the Company in this Agreement or a failure by the Company to comply with its

[***] = Certain information has been excluded from this exhibit because it is both not material and would likely cause competitive harm to the company if publicly disclosed.

covenants in this Agreement;provided that, (a) no Investor Related Party shall be entitled to recover special, consequential or punitive damages, except for any such special, consequential or punitive damages included in any third party claim in connection with which such Indemnified Party is entitled to indemnification and (b) no Investor Related Party shall be entitled to recover costs, losses, liabilities, damages, or expenses arising from the fraud, gross negligence or willful misconduct of an Investor Related Party or a dispute solely amongst Investor Related Parties to which the Company is not a party.

Section 10.2Additional Limitations on Indemnification. The Company’s maximum aggregate liability under thisArticle Xwill be limited to the aggregate principal amount of the Notes outstanding on such date, but in no event greater than the aggregate Commitment. Notwithstanding anything to the contrary contained herein, any damages otherwise indemnifiable under thisArticle X shall be reduced by the amount of insurance proceeds actually recovered by the Investor Related Parties in respect of such damages (net of costs of collection, deductibles and retro-premium adjustments). Damages shall be determined without duplication of recovery by reason of the state of facts giving rise to such damages constituting a breach of more than one representation or warranty. Any claim for indemnification relating to a breach of a representation and warranty must be made in writing no later than the earlier of (a) one (1) year after the payment in full in cash and discharge of all Notes then outstanding under the Indenture and (b) two (2) years after the Closing Date.

Section 10.3Indemnification Procedure. Promptly after any Investor Related Party (hereinafter, the “Indemnified Party”) has received notice of any indemnifiable claim hereunder, or the commencement of any action, suit or proceeding by a third person, which the Indemnified Party believes in good faith is an indemnifiable claim under this Agreement, the Indemnified Party shall give the indemnitor hereunder (the “Indemnifying Party”) written notice of such claim or the commencement of such action, suit or proceeding, but failure to so notify the Indemnifying Party will not relieve the Indemnifying Party from any liability it may have to such Indemnified Party hereunder except to the extent that the Indemnifying Party is materially prejudiced by such failure. Such notice shall state the nature and the basis of such claim to the extent then known. The Indemnifying Party shall have the right to defend and settle, at its own expense and by its own counsel who shall be reasonably acceptable to the Indemnified Party, any such matter as long as the Indemnifying Party pursues the same diligently and in good faith. If the Indemnifying Party undertakes to defend or settle, it shall promptly notify the Indemnified Party of its intention to do so, and the Indemnified Party shall cooperate with the Indemnifying Party and its counsel in all commercially reasonable respects in the defense thereof and the settlement thereof. Such cooperation shall include, but shall not be limited to, furnishing the Indemnifying Party with any books, records and other information reasonably requested by the Indemnifying Party and in the Indemnified Party’s possession or control. Such cooperation of the Indemnified Party shall be at the cost of the Indemnifying Party. After the Indemnifying Party has notified the Indemnified Party of its intention to undertake to defend or settle any such asserted liability, and for so long as the Indemnifying Party diligently pursues such defense, the Indemnifying Party shall not be liable for any additional legal expenses incurred by the Indemnified Party in connection with any defense or settlement of such asserted liability;provided, however, that the Indemnified Party shall be entitled (a) at its expense, to participate in the defense of such asserted liability and the negotiations of the settlement thereof and (b) if (i) the Indemnifying Party has failed to assume the defense or employ counsel reasonably acceptable to the Indemnified Party or (ii) if the defendants in any such action

[***] = Certain information has been excluded from this exhibit because it is both not material and would likely cause competitive harm to the company if publicly disclosed.

include both the Indemnified Party and the Indemnifying Party and counsel to the Indemnified Party (including in house counsel) shall have concluded that there may be reasonable defenses available to the Indemnified Party that are different from or in addition to those available to the Indemnifying Party or if the interests of the Indemnified Party reasonably may be deemed to conflict with the interests of the Indemnifying Party, then the Indemnified Party shall have the right to select one firm of separate counsel and to assume such legal defense and otherwise to participate in the defense of such action, with the reasonable expenses and fees of such separate counsel and other expenses related to such participation to be reimbursed by the Indemnifying Party as incurred. Notwithstanding any other provision of this Agreement, neither the Indemnifying Party nor the Indemnified Party shall settle any indemnified claim without the consent of the other (such consent not to be unreasonably withheld), unless the settlement thereof imposes no liability or obligation on, and includes a complete release from liability of, and does not include any admission of wrongdoing or malfeasance by such other party. The remedies provided for in thisArticle X are cumulative and are not exclusive of any remedies that may be available to a party at law or in equity or otherwise.

ARTICLE XI

EXISTING NOTES MATTERS

Section 11.1Exchange of Existing Notes. Upon the delivery by the Existing Investors to the Company of all the outstanding principal amount of the Existing Notes in exchange for an equal principal amount of Notes, the Existing Purchase Agreement shall automatically be deemed terminated and the parties thereto shall be released from their obligations thereunder;provided, that this Section 11.1 shall not apply in the event the Closing does not take place.
