Opus South assigned all of the landlord’s interest in the Lease to Oaklawn Alliance, L.L.C. on December 3, 1998, and Oaklawn Alliance, L.L.C. further assigned all of the landlord’s interest in the Lease to Landlord on November 15, 2001.

B. Pursuant to Section 18(j) of the Lease, upon Tenant’s approval of the Tenant’s Expansion Cost Proposal, the terms of the Lease were to be automatically amended to provide, among other things, that the Tenant would have an option to terminate the Lease as to the Expansion Building only, at any time after the end of the seventh (7^th) anniversary of the Expansion Commencement Date upon certain terms and conditions (the “Termination Right”). Tenant approved the Tenant’s Expansion Cost Proposal, and the Expansion Commencement Date was (i) for the First Floor and Second Floor of the Expansion Building, September 18, 2000, and (ii) for the Third Floor of the Expansion Building, October 16, 2000. Accordingly, the Lease has been automatically amended to include, among other things, the Termination Right.
