WHEREAS, any capitalized term used herein and not otherwise defined shall have the meaning ascribed to such term in the Loan Agreement.

NOW, THEREFORE, in consideration of the premises and for other good and valuable consideration, the receipt and adequacy of which are hereby acknowledged, and in order to induce the Lenders to enter into the Omnibus Amendment, the Guarantor hereby agrees for the benefit of the Administrative Agent and the Lenders as follows:

To the extent that, from and after the date hereof, (a) the Borrower enters into any Lease (a “Future Lease”), or enters into any supplement, amendment or other modification of a Lease granting the tenant thereunder more term and/or additional space or memorializing the exercise by any tenant pursuant to such tenant’s Lease of any option to extend the term of such Lease or to expand the space demised to such tenant under such Lease (a “Lease Modification”), or (b) a tenant under any Lease existing as of the date hereof exercises an option existing in such Lease as of the date hereof to extend the term of such Lease or to expand the space demised to such tenant under such Lease and no supplement, amendment or other modification of such Lease is entered into to memorialize

such exercise (a “Lease Option Exercise”; a Future Lease, a Lease Modification, or a Lease Option Exercise, a “Subject Lease Transaction”), the Guarantor absolutely and unconditionally guarantees to the Administrative Agent and the Lenders and their successors, endorsees and assigns, (i) the prompt payment of all obligations of the landlord in respect of such Subject Lease Transaction to pay tenant improvement costs and allowances and leasing commissions, (ii) the prompt performance of all obligations of the landlord in respect of such Subject Lease Transaction to perform landlord work and other capital expenditures in order to make the space demised under such Subject Lease Transaction ready for initial occupancy (including initial occupancy after any such Lease Modification or Lease Option Exercise) by the tenant thereunder and/or as a condition to such tenant’s obligation to commence the payment of rent thereunder, and (iii) the prompt payment and performance of all other obligations of the landlord under such Subject Lease Transaction to make the space demised under such Subject Lease Transaction ready for initial occupancy (including initial occupancy after any such Lease Modification or Lease Option Exercise) by the tenant thereunder and/or as a condition to such tenant’s obligation to commence the payment of rent thereunder, in each case of clauses (i), (ii) and (iii), as and when such obligations are due (collectively, the “Guaranteed Obligations”); provided, however, the Guaranteed Obligations shall not include the payment or performance of any landlord obligation during any free rent period granted to the tenant under such Subject Lease Transaction, other than the payment and performance of landlord obligations to make the space demised under such Subject Lease Transaction ready for initial occupancy (including initial occupancy after any such Lease Modification or Lease Option Exercise) or that landlord has otherwise agreed to pay or perform to achieve the initial buildout (including the initial buildout after any such Lease Modification or Lease Option Exercise) of the space demised under such Subject Lease Transaction. For the avoidance of doubt, a Subject Lease Transaction shall not include (x) any Lease or any supplement, amendment or other modification of any Lease entered into by or on behalf of Administrative Agent or any Lender or any of their respective agents, designees, successors and assigns, or any conservator, trustee, receiver or the like appointed by any of the foregoing, (y) any option to extend the term of a Lease or to expand the space demised to a tenant under a Lease that is exercised by the tenant under such Lease, or any Lease Modification memorializing such exercise that is entered into, at any time following the occurrence of an Event of Default, or (z) any option to extend the term of a Lease or to expand the space demised to a tenant under a Lease, or any Lease Modification memorializing such option, that, in either case, becomes effective following the Maturity Date (or, if earlier, the occurrence of an Event of Default).

The Guarantor acknowledges that one or more demands for payment may be made under this Guaranty.
