The parties now wish to further extend the term of the Fixed Rate Renewal Term, and to that end hereby amend and restate in its entirety the definition of “Maximum Option Period” in Appendix A to the Facility Lease as follows:

“Maximum Option Period” shall mean the period ending at midnight on December 31, 2033.”

1.2    Sections 3(a)(i) through (iii) of the Facility Lease are hereby deleted.

    1.3    Section 3(a)(iv) of the Facility Lease is hereby amended and restated in its entirety as follows:

(iv) on June 30, 2021, and on each Basic Rent Payment date thereafter, to and including December 31, 2033, an amount equal to$2,679,400.”

    1.4    Amendment No. 3 to the Facility Lease introduced to the Facility Lease a new “Schedule 4—Fixed Rate Renewal Term Casualty Values”, and a new “Schedule 5—Fixed Rate Renewal Term Special Casualty Values.” Both such Schedules are hereby deleted, and such Schedules are hereby amended and restated in their entirety with the Schedule 4—Fixed Rate Renewal Term Casualty Values and Schedule 5—Fixed Rate Renewal Term Special Casualty Values that are attached to and made a part of this Amendment No. 4 (sometimes referred to herein as “Restated Schedule 4” and “Restated Schedule 5,” respectively).

1.5     Subparagraphs (ii) and (iii) of the definition of “Casualty Value” in Appendix A to the Facility Lease are hereby amended and restated in their entirety as follows:

“(ii) during the Fixed Rate Renewal Term, the percentage of Facility Cost set forth opposite such date in Schedule 4—Fixed Rate Renewal Term Casualty Values to the Facility Lease attached hereto; and

(iii) during the Fair Market Renewal Term, shall mean the unamortized portion, as of such Basic Rent Payment Date, of the Fair Market Sales Value of the Undivided Interest, determined by the straight-line amortization of such Fair Market Sales Value at the commencement of the Fair Market Value Renewal Term over the period from such commencement date through the then remaining term of the License, determined pursuant to the Appraisal Procedure, all as set forth in a schedule to be prepared prior to the commencement of such Renewal Term.

1.6    Subparagraphs (ii) and (iii) of the definition of “Special Casualty Value” in Appendix A to the Facility Lease are hereby amended and restated in their entirety as follows:

(ii) during the Fixed Rate Renewal Term, the percentage of Facility Cost set forth opposite such date in Schedule 5—Fixed Rate Renewal Term Casualty/Special Casualty Values to the Facility Lease attached hereto; and

(iii) during the Fair Market Renewal Term, the amount equal to:

(A)the present value (declining in semi-annual steps over such Renewal Term and discounted at a rate of 10%) of the remaining Basic Rent payable from time to time in respect of the Undivided Interest for such Renewal Term, plus

(B)the present value of the anticipated Fair Market Sales Value of the Undivided Interest as of the last day of such Renewal Term (increasing in semi-annual steps over such Renewal Term and discounted at a rate of 10%),

all as set forth in a schedule to be prepared prior to the commencement of such Renewal Term.

    1.7     The Lessee and the Lessor acknowledge and agree that the calculation of the Casualty Values set forth in Restated Schedule 4 attached hereto and the Special Casualty Values set forth in Restated Schedule 5 attached hereto for the Fixed Rate Renewal Term were separately negotiated by the parties as a liquidated amount calculated to reimburse the Lessor for the loss of the Undivided Interest and the Real Property Interest due to the occurrence of an Event of Loss or Deemed Loss Event, as the case may be. The parties further acknowledge and agree that such Casualty Values and Special Casualty Values are not intended to be indicative of any current or future Fair Market Sales Value and shall not be taken into account in determining the Fair Market Sales Value if the Lessee exercises its purchase option pursuant to Section 13(c) of the Facility Lease at the end of the Fixed Rate Renewal Term (as extended by this Amendment No. 4) or the Fair Market Renewal Term.

    1.8    The Lessee and the Lessor further acknowledge and agree that the amounts set forth in Restated Schedule 4 and Restated Schedule 5 have been agreed to by the parties with each party utilizing certain assumptions ad projections (which may or may not be assumptions and projections used in common by the other party) concerning the Fair Market Sales Value of the Undivided Interest as of the date of this Amendment No. 4. The parties intend that such assumptions and projections shall not be used for any purpose (including, but without limitation, establishing a Fair Market Sales Value for the Undivided Interest or a Fair Market Sales Value of any property or service, or supporting or rebutting any calculation, determination or position concerning any Fair Market Sale Value, at any time, whether for purposes of option exercise, exercise of remedies, post-lease term operation and support or any other matter or circumstance) other than the specific purposes for which provision is made by this Amendment No. 4.
