This Second Addendum is made as of this 1st day of December, 2022 by and between Old Gettysburg Associates IV L.P., a Pennsylvania limited partnership (“Landlord”), and Select Medical Corporation, a Delaware corporation ("Tenant").

A.Landlord and Tenant are parties to that certain Office Lease Agreement dated August 25, 2006 (thereto, the “Original Lease”), pursuant to which Landlord leased to Tenant, and Tenant leased from Landlord, approximately 47,864 rentable square feet of space known as 4714 Gettysburg Road, Mechanicsburg, Pennsylvania.

B.    Landlord and Tenant are parties to that certain First Addendum to Lease Agreement dated November 1, 2012 (“First Addendum”), pursuant to which the rental amount and escalator under the Lease was modified. The Original Lease, as modified by the First Addendum, is hereinafter referred to as the “Lease”. All capitalized terms not otherwise defined herein shall have the meanings ascribed to them in the Lease.

C.    Landlord and Tenant now desire to amend the Lease as hereinafter set forth.

NOW, THEREFORE, in consideration of the mutual covenants and promises contained herein, and intending to be legally bound hereby, Landlord and Tenant amend the following terms contained in the Lease as follows:

1.The Term of the Lease, which would otherwise have expired on midnight January 31, 2023, is hereby extended for five years through midnight January 31, 2028.

2.The Annual Base Rental under the Lease during such five-year renewal period shall be as follows:

February 1, 2023 – January 31, 2024 $1,196,600 ($25.00/square foot)

February 1, 2024 – January 31, 2025 $1,256,430 ($26.25/square foot)

February 1, 2025 – January 31, 2026 $1,319,251.50 ($27.56/square foot)

3.    There will be no Operating Expense due and payable by the Tenant to the Landlord under the Lease during such renewal term.

4.    Tenant will have an option to renew the lease beyond January 31, 2028 at the fair market value rental rate, as determined by the same process used by Landlord and Tenant in the past to determine the rental rates for the Lease and other leases for spaces in the buildings located on Gettysburg Road in Mechanicsburg, Pennsylvania. That process involves Tenant’s obtaining an appraisal that is approved by Landlord and Tenant’s board of directors. Tenant may exercise such right by giving written notice of its decision to Landlord by not later than February 1, 2027.

5.    All other terms and conditions contained in the Lease and not amended hereby shall remain in full force and effect.

IN WITNESS WHEREOF, the parties have caused this Second Addendum to be duly executed on the day and year first set forth above.
