Base Rent and Additional Rent, as defined in Paragraph 4.B below, with the exception of the initial Base Rent as provided in Paragraph 4.C below, shall be paid on or before the first (1st) day of each month. Base Rent and Additional Rent shall be payable without notice or demand and without any deduction, offset, or abatement, in lawful money of the United States of America. Base Rent and Additional Rent shall be paid directly to Sublessor at the applicable address set forth below Sublessor’s signature to this Sublease or such other address as may be designated in writing by Sublessor. Base Rent and Additional Rent for any period during the Term hereof which is for less than one (1) month of the Term shall be a pro rata portion of the monthly installment based on a thirty (30) day month. If an increase in Base Rent becomes effective on a date other than the first day of a calendar month, the Base Rent for that month shall be the sum of the two applicable rates, each prorated for the portion of the month during which the rate is in effect.

The “Property Management Fee” shall equal three percent (3.00%) of Base Rent due from Tenant. Tenant shall pay the Property Management Fee in accordance with Section 9.2 with respect to the entire Term, including any extensions thereof or any holdover periods by Tenant, regardless of whether Tenant is obligated to pay Base Rent, Operating Expenses or any other Rent with respect to any such period or portion thereof. During the Abatement Period (and any period of occupancy prior to the Term as further described in Section 9.5), the Property Management Fee shall be calculated as if Tenant were paying Seventy-Five Thousand Two Hundred Forty and 00/100 Dollars ($75,240.00) per month for Base Rent.

Notwithstanding anything to the contrary contain herein, so long as Tenant is not in Default under this Lease, for the period commencing on the Commencement Date through the last day of the 30th full month after the Commencement Date (the “Partial Abatement Period”), Tenant shall only be required to pay Base Rent with respect to 11,000 rentable square feet of the Premises. Commencing on the first day of the 31st full month after the Commencement Date, Tenant shall commence paying Base Rent with respect to the entire Premises.

Notwithstanding anything to the contrary contained herein and provided that Tenant faithfully performs all of the terms and conditions of the Lease, as amended by this Third Amendment, Landlord hereby agrees to abate Tenant's obligation to pay monthly Base Rent for the first ten (10) full calendar months of the Extended Term. During such abatement periods, Tenant shall still be responsible for the payment of all of its other monetary obligations under the Lease, as amended. In the event of a default by Tenant under the terms of the Lease, as amended, that results in early termination pursuant to the provisions of Section 13.A of the Original Lease, then as a part of the recovery set forth in Section 13.B of the Original Lease, Landlord shall be entitled to the recovery of the monthly Base Rent that was abated under the provisions of this Section 5. The amount of Base Rent to be abated pursuant to this Section 5 above may be referred herein as the "Abated Rent Amount." Notwithstanding the foregoing or anything to contrary contained herein, upon written notice to Tenant, Landlord shall have the option to purchase all or any portion of Tenant's Abated Rent Amount by paying such amount to Tenant, in which case the amount so paid to Tenant shall nullify an equivalent amount of abatement of Tenant's Base Rent as to the period so designated by Landlord in Landlord's written notice to Tenant.

In the event construction of the Phase 2 is not complete (as evidenced per the prior sentence) by December 31, 2024 (the "Construction Deadline Date"), then Landlord may elect, in its sole and absolute discretion, that the entirety of the amount of any Partial Base Rent Abatement that has not then been repaid by Tenant on an amortized basis pursuant to the schedule above as of the Construction Deadline Date (i.e., a total of $3,856,755.64) shall become immediately due and payable as Additional Rent.

Such right to abate Base Rent and ​’s Share of Direct Expenses shall be ​’s sole and exclusive monetary remedy for rent abatement at law or in equity for an Abatement Event.
