2 Quarterly Financials on or prior to the Extended Delivery Date and (b) consents and agrees, effective as of the date of this Agreement, that the Company may deliver the Q-2 Quarterly Financials on or prior to the Extended Delivery Date (collectively, the “Consents”); provided, however that (x) the failure by the Company to deliver the Q-1 Quarterly Financials and the Q-2 Quarterly Financials on or prior to the Extended Delivery Date shall constitute an immediate Event of Default and (y) by its signature below the Company acknowledges and agrees that in connection with any future delivery of financial statements and related certifications under Sections 7.1 and/or 7.2 of the Note Purchase Agreement that the delivery of (i) preliminary financial statements and/or (ii) certifications required under Section 7.2 of the Note Purchase Agreement in a form different than the certification presented with the financial statements for the fiscal quarter ended September 30, 2021, in each case under clauses (i) or (ii), will not be in the respective forms required under the Note Purchase Agreement. Except as expressly provided herein, the foregoing Consents shall not constitute (a) a modification or alteration of the terms, conditions or covenants of the Note Purchase Agreement, the Notes or any other document entered into in connection therewith, or (b) a waiver, release or limitation upon the exercise by the Noteholders of any of their rights, legal or equitable, hereunder or under the Note Purchase Agreement, the Notes or any other document entered into in connection therewith. Except as set forth above, each of the Noteholders reserves any and all rights and remedies which it has had, has or may have under the Note Purchase Agreement, the Notes or any document entered into in connection therewith. 3. AMENDMENTS TO THE NOTE PURCHASE AGREEMENT. The Note Purchase Agreement is hereby amended as set forth below (collectively, the “Amendments”): 3.1 Section 7 of the Note Purchase Agreement is hereby amended by adding a new Section 7.5 to read as follows: 7.5. Senior Financial Officer Conference Calls. Until such time as the Company shall have delivered the Q-1 Quarterly Financials and Q-2 Quarterly Financials to the holders of Notes, within 15 days after the end of each quarterly fiscal period commencing with the fiscal quarter ended September 30, 2022 a Senior Financial Officer will host a noteholder update conference call to report on the status of the Company and to respond to questions from the holders of Notes. In addition, within 15 days after the delivery of the Q-1 Quarterly Financials and Q-2 Quarterly Financials to the holders of Notes, a Senior Financial Officer will host an additional noteholder update conference call to report on the status of the Company and to respond to questions from the holders of Notes. 3.2 Section 9 of the Note Purchase Agreement is hereby amended by adding a new Section 9.10 to read as follows: 9.10. Most Favored Lender. (a) If at any time any lender or agent under any Principal Credit Facility is paid any fee or other consideration (other than legal counsel fees and expenses) greater

3 than the equivalent fees being paid to the holders of Notes under the First Amendment in connection with any similar amendment, consent and waiver, including the RCF Consent, then the holders of Notes shall (concurrently with the provision of such consideration to such lender or agent) be provided with such additional equivalent consideration on a pro rata basis. (b) If at any time between March 31, 2022 and on or prior to the date on which the Company delivers the Q-1 Quarterly Financials and the Q-2 Quarterly Financials to the holders of Notes any Principal Credit Facility is modified and/or amended to include any covenant or event of default (whether set forth as a covenant, undertaking, event of default, restriction or other such provision not set forth in this Agreement or that would be more beneficial to the holders of the Notes than any analogous provision contained in this Agreement, and whether included as a new provision in a new or existing Principal Credit Facility or by way of amendment or other modification of an existing provision or any defined term used therein) not included in this Agreement or that would be more beneficial to the holders of the Notes than any analogous provision included in this Agreement (any such covenant or event of default, an “Additional Provision”), then the Company will, within three Business Days after the inclusion of such Additional Provision in such Principal Credit Facility, deliver written notice thereof to each holder of a Note. Such notice shall be signed by a Responsible Officer and shall refer to the provisions of this Section 9.10 and shall set forth a verbatim statement of such Additional Provision and any defined terms used therein, and related explanatory calculations, as applicable. Thereupon, unless waived in writing by the Required Holders within three Business Days after receipt of such notice by the holders of the Notes, such Additional Provision (and any related definitions) will be deemed automatically incorporated by reference into this Agreement, mutatis mutandis, as if set forth fully herein, without any further action required on the part of any Person, effective as of the date that such Additional Provision became effective under such Principal Credit Facility. Thereafter, upon the request of any holder of a Note, the Company will, at its expense, enter into any additional agreement or amendment to this Agreement reasonably requested by such holder evidencing any of the foregoing. (c) So long as no Default or Event of Default has occurred and is continuing: (i) if any Additional Provision incorporated into this Agreement pursuant to this Section 9.10 is amended or otherwise modified in each relevant Principal Credit Facility with the effect that such Additional Provision is made less restrictive or otherwise less onerous on the Company and its Subsidiaries, then such Additional Provision will be deemed so amended in this Agreement, without any further action required on the part of any Person, effective as of the date of such amendment or modification in each relevant Principal Credit Facility, (ii) if any Additional Provision incorporated into this Agreement pursuant to this Section 9.10 is removed from each relevant Principal Credit Facility, then such Additional Provision will be deemed removed from this Agreement, without any further action required on the part of any Person, effective as of the date of such removal from each relevant Principal Credit

4 Facility, and (iii) if each Principal Credit Facility including an Additional Provision incorporated into this Agreement pursuant to this Section 9.10 is terminated and no amounts are outstanding thereunder, then such Additional Provision will be deemed removed from this Agreement, without any further action required on the part of any Person, effective as of the date of such termination, provided that (x) except as provided in Section 18, this Agreement shall not be amended to remove any covenant, undertaking, event of default, restriction or other provision included in this Agreement (other than any Additional Provision included in this Agreement by operation of Section 9.10(a)) or to make any such provision less restrictive on the Company and its Subsidiaries, and (y) if any lender or agent under any Principal Credit Facility is provided any consideration for the amendment or other modification of such Principal Credit Facility, then the holders of Notes shall (concurrently with the provision of such consideration to such creditor or agent) be provided with equivalent consideration on a pro rata basis, and no such amendment, modification or removal of such Additional Provision in or from this Agreement shall be effective unless and until such equivalent consideration is provided to the holders of Notes. 3.3 Schedule B to the Note Purchase Agreement is hereby amended by adding the following new defined terms in their proper alphabetical order to read as follows: “Additional Provision” is defined in Section 9.10(b). “First Amendment” means that certain Note Purchase Agreement Amendment and Consent dated as of August 26, 2022 by and between the Company and the holders of the Notes party thereto, as amended from time to time. “Q-1 Quarterly Financials” is as defined in the First Amendment. “Q-2 Quarterly Financials” is as defined in the First Amendment. “RCF Consent” is as defined in the First Amendment. 4.
