          (d) If Tenant does not deliver its notice of intent to lease the Offered Space on or before the Exercise Deadline, or elects in such notice not to lease the Offer Space, then this right of first offer to lease the Offered Space will lapse and be of
no further effect and Landlord will have the right to lease the Offered Space to any third party; provided, however, if Landlord has not entered in a written lease or lease amendment, as applicable, for the Offered Space to a third party within one
