The Joint Venture was Landlord’s predecessor in interest as the owner of the Premises and landlord under the Lease.

All capitalized terms used in this Sixth Amendment and not otherwise defined herein shall have the meanings ascribed to them in the Lease.

Landlord and Tenant have now agreed to amend the Lease to extend the Extension Term and to make such other changes to the Lease upon the terms and conditions as described herein.

Extension of Expiration Date; Affirmation of Option. The parties acknowledge that Section 1 of the Fifth Amendment provides that the Extension Term shall expire on February 19, 2024 (the “Expiration Date”). The parties further acknowledge that Section 2 of the Fourth Amendment grants Tenant an Option, which allows Tenant to further extend the term of the Lease beyond the Expiration Date for an additional five (5) year period, which is subject to the terms and conditions set forth in Section 35 of the Original Lease, and which shall be treated as the Second Renewal Term under Section 35 of the Original Lease. The

parties further acknowledge that Section 1 of the Fifth Amendment affirmed the Option granted in Section 2 of the Fourth Amendment and provided for the Option to remain exercisable as provided under the terms and conditions of the Lease. The parties further acknowledge that, pursuant to Section 35 of the Original Lease, the Option for the Second Renewal Term shall be exercised by Tenant giving Landlord written notice of its intention to do so at least one hundred eighty (180) days before the end of First Renewal Term, which the parties agree for purposes of this Sixth Amendment shall mean the Expiration Date. The parties further acknowledge that the date that is one hundred eighty (180) days before the Expiration Date (without regard for any modifications made pursuant to this Section 1 of the Sixth Amendment) is August 23, 2023. Based on the foregoing facts, the parties hereby agree that, as of the Effective Date, the Expiration Date is hereby extended for an additional three (3) year period (the “New Extension Term”), to February 19, 2027, and the Option granted to Tenant for a Second Renewal Term pursuant to Section 35 of the Original Lease, as modified by the provisions of Section 2 of the Fourth Amendment, Section 1 of the Fifth Amendment, and this Section 1 of the Sixth Amendment, shall remain exercisable as provided under the terms and conditions of the Lease by Tenant giving Landlord written notice of its intention to do so on or before August 23, 2026. For the avoidance of doubt, provided that Tenant gives Landlord written notice of its intention to exercise the Option for the Second Renewal Term on or before August 23, 2026, and is not in default of any of the terms and conditions of the Lease, the Second Renewal Term shall extend from February 20, 2027 through February 19, 2032.
