“Right of First Refusal.

If Landlord issues a letter of intent to, or receives a bona fide offer from, a third party to lease any such additional space that is not then a part of the Premises (the “Third Party Offer”), Landlord shall promptly give Tenant written notice of such Third Party Offer. Tenant shall have ten (10) business days following receipt of such notice in which to elect in writing to lease such additional space on the terms and conditions in this Lease.

Such policies and/or certificates shall comply in all other respects with the provisions of Article VI of the Lease. In the event Tenant fails to deliver such policies and/or certificates, to Landlord’s reasonable satisfaction, within said 15-day period, then Landlord may, at its sole election, either (i) declare this Fourth Amendment to be null and void and of no force and effect, or (ii) allow the Lease, as modified pursuant to this Fourth Amendment, to continue in full force and effect, but declare an Event of Default under Section 14.1(c) of the Lease.

5

the agreements and understandings relating to the leasing of the Premises and the obligations of Landlord and Tenant in connection with such leasing. Landlord has not made, and Tenant is not relying upon, any warranties, or representations, promises or statements made by Landlord or any agent of Landlord, except as expressly set forth in the Lease, First Amendment, Second Amendment, Third Amendment and this Fourth Amendment.
