NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Borrowers, Guarantor, Administrative Agent and Signatory Lenders now agree to extend the maturity date of the Obligations owing to Administrative Agent and each Signatory Lender and to permit an Administrative Agent Advance in the amount of the Protective Advance Amount, all as more specifically set forth below.

1.Recitals. The parties hereto acknowledge and agree that the recitals set forth above are true and correct and are incorporated herein by this reference; provided, however, that such recitals shall not be deemed to modify the express provisions hereinafter set forth. Capitalized terms used herein but not defined shall have the meanings given to them in the Loan Agreement.

2.Maturity Date. All of the Obligations owing to Administrative Agent and each Signatory Lender, including (without limitation) all outstanding principal, accrued and unpaid interest, outstanding late charges, unpaid fees, and all other amounts outstanding under the Note (including but not limited to the Protective Advance Amounts outstanding under the Administrative Agent Advances) and the other Loan Documents owing to Administrative Agent or any Signatory Lender, shall be due and payable in full on February 6, 2025 (or such earlier date to which such Obligations may be accelerated in accordance with the terms of the Loan Agreement) (the “Extended Maturity Date”). Notwithstanding anything to the contrary in the Loan Agreement and the other Loan Documents, the “Maturity Date” with respect to the foregoing Obligations owing to Administrative Agent and each Signatory Lender shall be deemed to mean the Extended Maturity Date. Borrowers have no further options to extend the Maturity Date (and any prior

extension options have been terminated), and the provisions of this Section shall not excuse the Borrowers from paying interest that is due prior to maturity in accordance with the terms of Section 1.6.1 of the Loan Agreement or any other sum that is due prior to maturity pursuant to the Loan Documents.

3.Protective Advance.

(a)The Signatory Lenders, constituting the Required Lenders, hereby consent to Administrative Agent Advances in an aggregate amount equal to the Protective Advance Amount for the payment of Real Property Taxes, as more specifically set forth on Exhibit A attached hereto. Administrative Agent may condition the funding of such Administrative Agent Advances upon the delivery of such invoices, evidence of sums due, draw requests or other documentation as it may require.

(b)Each Signatory Lender hereby agrees to make the amount of such Lender’s Pro Rata Share of the Protective Advance Amount available to Administrative Agent, in same day funds, to such account of Administrative Agent as Administrative Agent may designate, as provided in Section 8.12 of the Loan Agreement.

(c)In accordance with Section 8.12(b) of the Loan Agreement, such Administrative Agent Advances constitute obligatory advances of all Lenders. The failure of any Lender to fund its Pro Rata Share of the Protective Advance Amount shall not relieve any other Lender of its corresponding obligation to do so, and no Lender shall be responsible for any other Lender’s failure to make its payment thereof.

(d)Borrowers and Guarantor hereby acknowledge and agree that the Administrative Agent Advance contemplated hereby shall constitute an advance of additional Loan proceeds and, after giving effect thereto, the outstanding principal balance of the Loan shall increase by the Protective Advance Amount advanced hereunder.

4.Debtor-in-Possession Financing. Borrowers hereby agree, prior to filing or commencing any prepackaged or otherwise prenegotiated proceeding under chapter 11 of the United States Bankruptcy Code, to provide each Lender with a copy of each debtor-in-possession financing agreement and restructuring support agreement entered into (or to be entered into) in support of any such proceeding, in the final form agreed to prior to filing or commencing such proceeding.

5.Waiver of Financial Covenants. For the avoidance of doubt, Section 5 of the Sixth Modification remains in full force and effect.

(a)Administrative Agent’s receipt of this Agreement duly executed by all parties hereto;

(b)Borrowers and Guarantor shall have delivered to Administrative Agent the following, each in form and substance satisfactory to Administrative Agent: (i) resolutions authorizing this Agreement and (ii) secretary’s certificates (including incumbency certificates) for Borrowers and Guarantor, which shall include certifications that there have been no changes to the organizational documents, certificates of formation, certificates of good standing, and applicable certificates of foreign qualification delivered to Administrative Agent in connection with the Seventh Modification; and

8.Obligors’ Representations and Warranties; Reaffirmation of Loan. Each Obligor hereby reaffirms all of the representations and warranties set forth in the Loan Documents (in each case, and with respect to each reference to any Loan Document contained in this Section 8, as such Loan Document is being amended hereby) to be true, accurate and correct in all material respects as of the Effective Date to the extent such representations and warranties are not matters which, by their nature, can no longer be true and correct as a result of the passage of time, and except for changes in circumstances arising from actions or events occurring after the date of the Loan Agreement that do not otherwise constitute a Default thereunder, including, without limitation, the execution of new Leases or new contracts that are not prohibited by the terms of the Loan Agreement or any other Loan Document. Each Obligor further represents and warrants that as of the Effective Date (a) the information included in the Beneficial Ownership Certification, if applicable, is true and correct in all respects; (b) to each Obligor’s knowledge, other than receipt of prepaid rents in the aggregate amount not exceeding $500,000, all of which have been deposited in the property accounts in which the Administrative Agent holds a security interest, no Default or Potential Default has occurred and is continuing (or will exist after giving effect to the satisfaction of the conditions to the effectiveness of this Agreement); (c) each Obligor is a limited liability company which is duly organized and validly existing under the laws of the State of Delaware; (d) other than as disclosed to the Administrative Agent in writing on or prior to the date hereof, there have been no material changes in formation documents of any Obligor since the inception of the Loan; (e) the execution and delivery of this Agreement do not contravene, result in a breach of, or constitute a default under, any mortgage, loan agreement, indenture or other contract or agreement to which any Obligor is a party or by which any Obligor or any of its properties may be bound (nor would such execution and delivery constitute such a default with the passage of time or the giving of notice or both), and do not violate or contravene any law, order, decree, rule, regulation or restriction to which any Obligor or any Property is subject; (f) this Agreement constitutes the legal, valid and binding obligations of each Obligor enforceable in accordance with its terms, except to the extent that such enforceability may be limited by laws generally affecting the enforcement of creditors’ rights; (g) the execution and delivery of, and performance under, this Agreement are within each Obligor’s power and authority without the joinder or consent of any other party and

have been duly authorized by all requisite action, and are not in contravention of any law, or of any Obligor’s articles of organization or operating agreement or of any indenture, agreement or undertaking to which any Obligor is a party or by which it is bound. Each Borrower hereby reaffirms all of its obligations under the Loan Documents, and acknowledges, confirms, stipulates, agrees, represents and warrants that it has no defense, claim, credit, offset or counterclaim to any of its obligations under any of the Loan Documents. Each Borrower further acknowledges the validity and enforceability of each Security Instrument as a first‑priority lien on the applicable Property, all improvements located thereon and all of the collateral described in such Security Instrument. Without limiting the foregoing, each Borrower reaffirms Administrative Agent’s right, following the occurrence and during the continuance of any Default, to apply any and all payments made by any Borrower or otherwise received by Administrative Agent or the Lenders with respect to the Loan, including without limitation all proceeds received from the sale or liquidation of any collateral, to the obligations owing by Borrowers under the Loan Documents in accordance with Section 7.2 of the Loan Agreement, and each Borrower acknowledges that it shall have no right to direct Administrative Agent as to such application or designate the portion of the obligation to be satisfied.

9.Release.

(a)Borrowers and Guarantor, for themselves and for each of their respective heirs, personal representatives, successors and assigns, hereby release and waive all claims and/or defenses they now may have against Administrative Agent, Lenders and their respective successors and assigns (collectively, the “Released Parties”) on account of any occurrence relating to the Loan, the Loan Documents and/or the property encumbered by the Security Instruments which accrued prior to the date hereof, including, but not limited to, any claim that Administrative Agent or any Lender (i) breached any obligation to Borrowers and/or Guarantor in connection with the Loan, (ii) was or is in any way involved with Borrowers and/or Guarantor as a partner, joint venturer, or in any other capacity whatsoever other than as a lender, (iii) failed to fund any portion of the Loan or any other sums as required under any document or agreement in reference thereto, or (iv) failed to timely respond to any offers to cure any defaults under any document or agreement executed by Borrowers, Guarantor or any third party or parties in favor of Administrative Agent or any Lender (collectively, the “Released Claims”). This release and waiver shall be effective as of the date of this Agreement and shall be binding upon Borrowers and Guarantor and each of their respective heirs, personal representatives, successors and assigns, and shall inure to the benefit of Administrative Agent, Lenders and their respective successors and assigns.

Borrowers and Guarantor have executed this Agreement voluntarily, with full knowledge of its significance, and with the express intention of effecting the legal consequences provided by a waiver of California Civil Code Section 1542.

10.Course of Dealing; Reservation of Rights. Administrative Agent, Signatory Lenders and Obligors hereby acknowledge and agree that:

(a)At no time shall any prior or subsequent course of conduct by Obligors, Administrative Agent or any Lender directly or indirectly limit, impair or otherwise adversely affect any of Administrative Agent’s or any Lender’s rights, interests or remedies in connection with the Loan and the Loan Documents or obligate Administrative Agent or any Lender to agree to, or to negotiate or consider an agreement to, any waiver of any obligation or default by Borrowers under any Loan Document or any amendment to any term or condition of any Loan Document.

(b)This Agreement does not alter, impair or affect in any fashion (or evidence the intent of any party to alter, impair or affect in any fashion) any and all past, present, and future claims, causes of action, damages, demands, costs, and other liabilities of any kind, direct or indirect, known or unknown, foreseen or unforeseen, which Administrative Agent or the Lenders (or any of them individually), or any of their respective officers, successors, assigns, or representatives, now has or may have in the future against any Obligor or their respective successors and assigns, and all persons acting by through, under, or under the control of any of the foregoing which relate to, arise from, or are connected with the Loans, in each case, except for the modifications to the Loan Agreement and other Loan Documents that are expressly provided in this Agreement. Except as expressly provided in this Agreement and except for the modifications to the Loan Agreement and other Loan Documents expressly provided in this Agreement, Administrative Agent and the Lenders reserve all rights and remedies against the Obligors, and all other terms and conditions of the Loan Agreement and other Loan Documents prior to the date hereof shall remain in full force and effect.

(c)Upon its effectiveness, this Agreement shall constitute a “definitive written agreement” under the Pre-Discussion Agreement.

Documents are hereby ratified and confirmed as valid, subsisting and continuing to secure the Obligations. Nothing herein shall in any manner diminish, impair, waive or extinguish the Note, the Loan Documents, the Obligations or the Liens created or secured by the Loan Documents, except for the modifications to the Loan Agreement that are expressly provided for in this Agreement. The execution and delivery of this Agreement shall not constitute a novation of the debt evidenced and secured by the Loan Documents.

12.Default. A default under this Agreement shall constitute a Default under the Note and other Loan Documents, subject to any applicable notice and cure or grace period expressly set forth in the Loan Documents. For avoidance of doubt, this Agreement is a Loan Document.

13.Miscellaneous. To the extent of any conflict between the Loan Documents and this Agreement, this Agreement shall control.

This Agreement (a) shall bind and benefit the parties hereto and their respective heirs, beneficiaries, administrators, executors, receivers, trustees, successors and assigns; (b) shall be governed by the laws of the State of California and United States federal law; and (c) may be executed in several counterparts, and by the parties hereto on separate counterparts, and each counterpart, when executed and delivered, shall constitute an original agreement enforceable against all who signed it without production of or accounting for any other counterpart, and all separate counterparts shall constitute the same agreement.

14.Reaffirmation of Guaranty. Guarantor, by signature below as such, for valuable consideration, the receipt and adequacy of which are hereby acknowledged, hereby consents to and joins in this Agreement and hereby declares to and agrees with Administrative Agent and Lenders that the Guaranty is and shall continue in full force and effect for the benefit of Administrative Agent and Lenders with respect to the Obligations, as amended by this Agreement, that there are no offsets, claims, counterclaims, cross-claims or defenses of Guarantor with respect to the Guaranty nor, to Guarantor’s knowledge, with respect to the Obligations, that the Guaranty is not released, diminished or impaired in any way by this Agreement or the transactions contemplated hereby, and that the Guaranty is hereby ratified and confirmed in all respects. Guarantor hereby reaffirms all of the representations and warranties set forth in the Guaranty, except to the extent such representations and warranties are matters which, by their nature, can no longer be true and correct as a result of the passage of time, and except for changes in circumstances arising from actions or events occurring after the date of the Guaranty that do not otherwise constitute a Default thereunder. Guarantor acknowledges that without this consent and reaffirmation, Administrative Agent and Signatory Lenders would not execute this Agreement or otherwise consent to its terms.

15.Electronic Signatures. This Agreement may be in the form of an Electronic Record and may be executed using Electronic Signatures (including, without limitation, facsimile and .pdf) and shall be considered an original, and shall have the same legal effect, validity and enforceability as a paper record. For purposes hereof, “Electronic Record” and “Electronic Signature” shall have the meanings assigned to them, respectively, by 15 USC §7006, as it may be amended from time to time. Borrowers and Guarantor hereby agree that as soon as reasonably possible, Borrowers and Guarantor will provide an original of this Agreement to Administrative

Agent that will include the wet signatures of Borrowers and Guarantor next to any Electronic Signatures.

16.Limited Recourse Provision. Neither Administrative Agent nor any Lender shall have any recourse against, nor shall there be any personal liability to, the members, shareholders, partners, beneficial interest holders or any other entity or person in the ownership (directly or indirectly) of any Borrower with respect to the obligations of any Borrower and Guarantor under the Loan. For purposes of clarification, in no event shall the above language limit, reduce or otherwise affect any Borrower’s liability or obligations under the Loan Documents, Guarantor’s liability or obligations under the Guaranty, or Administrative Agent’s and each Lender’s right to exercise any rights or remedies against any collateral securing the Loan.
