WHEREAS, Landlord and Tenant desire to amend the Lease as provided herein.

NOW, THEREFORE, in consideration of the premises and other good and valuable consideration, the mutual receipt and legal sufficiency of which the parties hereto hereby acknowledge, Landlord and Tenant hereby agree as follows:

1.Defined Terms. Capitalized terms used and not otherwise defined herein shall have the respective meanings ascribed thereto in the Lease.

2.Additional Storage Space.

(A)Subject to this Section 2 and to Article 2 of the Lease, as amended hereby, Landlord hereby leases to Tenant, and Tenant hereby hires and takes from Landlord, the portion of Lower Level 3 of the Building that is shown hatched in yellow on the schematic annexed as Exhibit "A" attached hereto and made a part hereof (such portion of Lower Level 3 of the Building, the "Second Additional Storage Space") for a term commencing on March 1, 2022 (the "Second Additional Storage Space Commencement Date") and ending on the Fixed Expiration Date. Tenant shall use the Second Additional Storage Space for storage purposes and for no other purpose. Landlord shall deliver vacant and exclusive possession of the Second Additional Storage Space to Tenant with all of the prior occupant's personal property removed therefrom and otherwise in broom-clean "as is" condition on the Second Additional Storage Space Commencement Date. Landlord shall have no obligation to perform any work or to make any installations in the Second Additional Storage Space in order to prepare the Second Additional Storage Space for Tenant's use thereof. Landlord shall provide sufficient electrical capacity to the Second Additional Storage Space solely for purposes of lighting therein, but shall have no obligation to clean the Second Additional Storage Space or to provide HVAC, gas, steam, or water thereto; provided, however, that Landlord shall provide fresh air to the Second Additional Storage Space (which fresh air is tempered during the winter) and general exhaust from the Second Additional Storage Space.

(B)At any time after the Second Additional Storage Space Commencement Date, Tenant, at Tenant's cost and expense, may elect to perform the work required to cause the electrical capacity supplied to the Second Additional Storage Space to be measured by Tenant's direct electricity meter, in which event Tenant shall pay the cost of such electrical capacity directly to the utility provider pursuant to an agreement between Tenant and such provider. Unless and until Tenant makes the foregoing election, Tenant's use of electricity in the Second Additional Storage Space shall be measured by a submeter, installed by Landlord at Landlord's cost and expense, from and after the Second Additional Storage Space Commencement Date (it being agreed that (i) Tenant shall not be required to pay for electricity for the Second Additional Storage Space until such submeter has been installed by Landlord, and (ii) Landlord's installation of such submeter shall not be deemed to be a delivery condition with respect to the Second Additional Storage Space for purposes of this Amendment). Landlord, at Landlord's cost and expense, shall maintain the submeter in the Second Additional Storage Space during any period of time that Tenant's use of electricity therein shall be measured by submeter. Tenant shall pay to Landlord, as additional rent, with respect to a particular period, an amount (the "Second Additional Storage Space Electricity Additional Rent") equal to one hundred three percent (103%) of the charge imposed by the utility company or other reputable provider for the

electrical capacity provided to the Second Additional Storage Space (including, without limitation, energy charges, demand charges, all applicable surcharges, time-of-day charges, fuel adjustment charges, rate adjustment charges, taxes and any other factors used by the utility company in computing its charges to Landlord) actually utilized by Tenant with the understanding that the Second Additional Storage Space Electricity Additional Rent shall be calculated based on submeter readings. Landlord shall give Tenant an invoice for the Second Additional Storage Space Electricity Additional Rent on a monthly basis, which invoice shall have annexed thereto a copy of the applicable invoice from the utility company or other reputable provider and the calculation of the aggregate amount set forth on such invoice. Tenant shall pay the Second Additional Storage Space Electricity Additional Rent to Landlord on or prior to the thirtieth (30th) day after the date that Landlord gives to Tenant each such invoice. Tenant shall not have the right to object to Landlord's calculation of the Second Additional Storage Space Electricity Additional Rent unless Tenant gives Landlord notice of any such objection on or prior to the sixtieth (60th) day after the date that Landlord gives Tenant the applicable invoice for the Second Additional Storage Space Electricity Additional Rent. If Tenant gives Landlord a notice objecting to Landlord's calculation of the Second Additional Storage Space Electricity Additional Rent, as aforesaid, then Tenant shall have the right to review Landlord's submeter readings and Landlord's calculation of the Second Additional Storage Space Electricity Additional Rent, at Landlord's offices or, at Landlord's option, at the offices of Landlord's managing agent, in either case at reasonable times and on reasonable advance notice to Landlord. Either party shall have the right to submit a dispute regarding the Second Additional Storage Space Electricity Additional Rent to an Expedited Arbitration Proceeding.

(C)Tenant shall pay Fixed Rent to Landlord for the Second Additional Storage Space:

(1)commencing on the Second Additional Storage Space Rent Commencement Date (defined below) and ending on December 14, 2023, in an amount equal to Three Hundred Twenty-Six Thousand Six Hundred Six Dollars and 40/100 Cents ($326,606.40) per annum ($27,217.20 per month);

The term "Second Additional Storage Space Rent Commencement Date" shall mean June 1, 2022.
