C.Landlord and Tenant desire to enter into this Agreement amending and confirming the Commencement Date and other matters under the Lease. For avoidance of doubt, this Agreement shall operate as an amendment to the Lease concerning all terms and provisions addressed and modified herein.

1.The date of “Substantial Completion” of “Landlord’s Work” (as such terms are defined in the Construction Agreement) is September 5, 2025, whereupon Landlord will be deemed to have tendered possession of the Premises to Tenant and Tenant will be deemed to have accepted possession of the Premises from Landlord, as more particularly provided in Section 2.5 of the Second Amendment.

2.The “Estimated Completion Date” (as defined in Section 2.2 of the Original Lease) is January 23, 2026. Pursuant to Section 2.3 of the Original Lease, because Substantial Completion of Landlord’s Work occurred prior to the Estimated Completion Date, Tenant shall pay to Landlord, as Additional Rent, within ten (10) days after invoice, an early completion bonus in an amount not to exceed the lesser of (i) the amount that Landlord is actually required to pay to the Building Contractor as an early completion bonus, and (ii) the cap amounts on Tenant’s obligation that are set forth in Section 2.3 of the Original Lease.

3.Notwithstanding anything otherwise provided above or in the Lease, the parties agree that the “Commencement Date” (as defined in the Lease Summary) shall be deemed to be, and is hereby amended to mean, October 1, 2025. Notwithstanding the foregoing amendment of

the Commencement Date, except with respect to the payment of Base Rent, all other obligations that are required to be paid and/or performed by Tenant under the Lease, to the extent applicable, shall commence to accrue as of the date of Substantial Completion of Landlord’s Work, including but not limited to Tenant’s obligations under Article 4 and Article 12 of the Original Lease.

5.Notwithstanding anything otherwise provided in the Lease, the “Rent Abatement” (as defined in the Lease Summary) is hereby amended to mean the Base Rent that would otherwise be payable under the Lease for the one hundred fifty-four (154) day period commencing on October 1, 2025, and continuing through March 4, 2026. During the Rent Abatement, only Base Rent is being abated and Tenant shall nevertheless be required to pay and discharge all other obligations of Tenant set forth in the Lease, commencing as of the date of Substantial Completion of Landlord’s Work.

6.Attached hereto as Attachment 1 is a schedule of the Base Rent payable for the Initial Term, commencing upon the expiration of the Rent Abatement, which has been determined in accordance with the “Base Rent” section of the Lease Summary.
