“any Security Document after delivery thereof shall for any reason cease (or shall be asserted in writing by the Issuer or any Guarantor to cease) to create a valid and perfected Lien to the extent required by the Security Documents (subject to the Intercreditor Agreement) on Collateral that is purported to be covered thereby (other than (x) in accordance with the terms of this Indenture or the terms of the Intercreditor Agreement or the Security Documents or (y) except to the extent that any such cessation of the Liens results from the failure of the administrative agent or the lender under the Credit Agreement or under the Priority Credit Agreement, as the case may be, in each case, as bailee for the Collateral Agent pursuant to the terms of the Intercreditor Agreement, to maintain possession of certificates actually delivered to it representing securities pledged under the Security Documents);”

“a default in any of the Company’s or any Guarantor’s obligations or agreements under the Credit Agreement or the Priority Credit Agreement where such default is not cured or waived within the time periods provided in the Credit Agreement or the Priority Credit Agreement, as the case may be, prior to such default becoming an “Event of Default” thereunder; or”

“The Obligations will be secured by a perfected Lien on the Collateral, subject to the Intercreditor Agreement, as provided in the Security Documents. The Collateral will also secure certain of the Company’s and the Guarantors’ existing obligations under the Credit Agreement and the Priority Credit Agreement, subject to the Intercreditor Agreement. Under the terms of the

Intercreditor Agreement, the proceeds of any collection, sale, disposition or other realization of Collateral received in connection with the exercise of remedies (including distributions of cash, securities or other property on account of the value of the Collateral in a bankruptcy, insolvency, reorganization or similar proceedings) will be applied in the order of priority set forth in the Intercreditor Agreement.”

“Each Holder of Notes, by its acceptance thereof, and the Trustee hereby designates and appoints the Collateral Agent as its agent under this Indenture and the Security Documents and each Holder by acceptance of the Notes consents and agrees to the terms of each Security Document, as originally in effect and as amended, supplemented or replaced from time to time in accordance with its terms or the terms of this Indenture, authorizes and directs the Collateral Agent to enter into the Security Documents and the Intercreditor Agreement, and irrevocably authorizes and empowers the Collateral Agent to perform its obligations and duties, exercise its rights and powers and take any action permitted or required thereunder that are expressly delegated to the Collateral Agent by the terms of this Indenture, the Security Documents and the Intercreditor Agreement.”

“Each Holder of a Note, by accepting such Note, agrees that, for purposes of the Intercreditor Agreement, (x) with respect to the Pari Passu Intercreditor Agreement, (i) the Trustee shall be the “Initial Other Representative” thereunder, (ii) the Collateral Agent shall be the “Initial Other Collateral Agent” thereunder, (iii) this Indenture shall constitute the “Initial Other First Lien Agreement” thereunder and all references to the “Initial Other First Lien Agreement” contained therein shall be deemed to refer to this Indenture and (iv) all of the Notes Obligations shall constitute “Initial Other First Lien Obligations” thereunder and (y) with respect to the Priority Intercreditor Agreement, (i) the Collateral Agent shall be the “Junior Lien Indenture Collateral Agent” thereunder, (ii) this Indenture shall constitute the “Junior Lien Indenture” thereunder and all references to the “Junior Lien Indenture” contained therein shall be deemed to refer to this Indenture and (iii) all of the Notes Obligations shall constitute “Junior Lien Indenture Obligations” thereunder. The Trustee and the Collateral Agent shall be bound by the terms of the Intercreditor Agreement and each Holder of a Note, by accepting such Note or beneficial interest therein, agrees to all the terms and provisions of the Intercreditor Agreement and the other Security Documents. Notwithstanding anything to the contrary herein or in the other Indenture Documents, (i) this Indenture, the Liens and security interests granted to the Collateral Agent pursuant to the Security Documents and all rights and obligations of the Trustee and the Collateral Agent under the Indenture Documents are expressly subject to the Intercreditor Agreement and (ii) the exercise of any right or remedy by the Trustee or the Collateral Agent under the Indenture Documents is subject to the limitations and provisions of the Intercreditor Agreement. The Holders authorize the Trustee and the Collateral Agent to communicate with the

Lender (as defined in the Credit Agreement) under the Credit Agreement and the Lender (as defined in the Priority Credit Agreement) under the Priority Credit Agreement, as applicable, and any other Person who is, or becomes a party to the Intercreditor Agreement, with respect to any matter, including, without limitation, the Obligations, the Obligations (as defined in the Credit Agreement) under the Credit Agreement, the Obligations (as defined in the Priority Credit Agreement) under the Priority Credit Agreement, the Intercreditor Agreement, the Indenture Documents, and any other matter relating to, or arising out of such matters. Each Holder of a Note, by accepting such Note, agrees and hereby authorizes and directs the Collateral Agent and Trustee to execute the Intercreditor Agreement (including, for the avoidance of doubt, each of the Priority Intercreditor Agreement and the Pari Passu Intercreditor Agreement). Each Holder, by accepting a Note, hereby agrees that such Holder shall comply with the provisions of the Intercreditor Agreement applicable to it in its capacities as such to the same extent as if such Holder were party thereto. Without limiting any of the rights and protections (including indemnities) of the Trustee or Collateral Agent hereunder and notwithstanding any provisions in this Indenture or the other Indenture Documents to the contrary, in the event of any conflict or inconsistency between the terms of the Intercreditor Agreement and the terms of this Indenture or the other Indenture Documents, the terms of the Intercreditor Agreement shall govern.”

“SCHEDULE 8

1. To the extent constituting a Commercial Tort Claim, all of each Grantor’s rights and interests in the professional negligence claim against a prior legal advisor of the Grantors, which negligence allegedly directly and proximately triggered, on or about October 20, 2023, a fundamental change under an indenture governing the Notes Issuer’s then-existing senior convertible notes.”
