(b)Eighth Floor Termination Payment. Subject to the terms of this Section 1(b), Tenant shall pay to Landlord simultaneously with its execution of this Agreement, in immediately available funds, the amount of $15,656,000.00 (the “Eighth Floor Termination Payment”) as consideration for Landlord entering into this Agreement with respect to the Eighth Floor Premises.
