11.1 Title to all improvements constructed by Tenant within the Premises following the Commencement Date shall be and remain in Tenant for and during the entire Term of this Lease, and on the expiration or earlier termination of this Lease, Tenant hereby covenants and agrees that the sole right to possess and use the same (but not Tenants Property) shall automatically pass to and be vested in Landlord without payment or consideration of any kind, unless Landlord provides Tenant with written notice at the time Landlord approves such improvements, that Landlord shall require Tenant to remove such improvements (or a specified portion thereof) at its sole cost and expense prior to the expiration of the Term, or to the extent permitted under the terms of this Lease any earlier termination of the Term, provided that Tenant is afforded a reasonable advance notice of such earlier termination to effect such removal.
11.2 Tenant shall have the right, at any time and from time to time during the Term of this Lease, to make, at its sole cost and expense Alterations to the Premises, subject, however, in all cases, to the following:
(a) All Alterations shall be made promptly in a good and workmanlike manner on a lien-free basis and in compliance with all applicable Legal Requirements, and any national or local Insurance Rating Bureau, or any other body hereafter exercising similar functions.
(b) The cost of all Alterations shall be paid by Tenant, so that the Property shall at all times be free from all liens for labor and material supplied or claimed to have been supplied to the Premises and free from all liens, encumbrances or security interests.
(c) Tenant shall not make any Alterations (i) to any portion of the Property described in Section 9.2, without Landlords prior written approval (including approval of all plans and specifications) to be given or withheld in Landlords sole and absolute discretion, (ii) to the exterior of the Buildings or Property if such Alterations would change the appearance of the Property or any part thereof, or (iii) that are not included in clauses (i) or (ii) above but cost more that Fifty Thousand Dollars ($50,000) without Landlords prior written approval (including approval of all plans and specifications, if any), which approval shall not be unreasonably withheld, conditioned or delayed. Within fifteen (15) days after the receipt of plans and specifications from Tenant requiring Landlords approval, Landlord shall notify Tenant in writing of its approval of the plans and specifications or the reasons for its rejection thereof. Landlord shall be deemed to have approved such plans and specifications or such Alterations if it fails to give Tenant a rejection notice within fifteen (15) days after receipt by Landlord of Tenants plans and request for approval.
11.3 Except as expressly set forth in this Lease, Landlord shall have no right to make any Alterations to the Premises (as distinguished from repairs and maintenance) without the prior written consent of Tenant, which consent Tenant may grant or withhold in its reasonable discretion.
11.4 Landlord, at Tenants sole cost and expense, shall provide reasonable cooperation with Tenant with respect to Tenants efforts to secure building and other permits or authorizations that may be required from time to time by Tenant in connection with the performance of any Alterations. Any reasonable costs incurred by Landlord in connection with Landlords (or Landlords construction consultants) review of any plans submitted to Landlord by Tenant shall be paid by Tenant as Additional Rent upon thirty (30) days written demand therefore by Landlord.
