Improvements and Alterations (a) Landlord's sole construction obligation under this Lease is set forth in the Work Letter attached hereto as Exhibit "B". (b) Tenant shall not make any alterations, additions or improvements to the Premises (collectively, "Alterations") without (i) the prior written consent of Landlord, and (ii) compliance with such nondiscriminatory requirements concerning such Alterations as may be imposed by Landlord from time to time. Without limiting the foregoing, Landlord may require, at a minimum, compliance with the requirements set forth in Exhibit "C" attached hereto. All Alterations shall be made by Tenant, at Tenant's sole cost and expense, and shall be diligently prosecuted to completion. The cost of any modifications of Project improvements outside or inside of the Premises required by any governmental agency as a condition or the result of Tenant's Alterations shall be borne by Tenant. Any contractor or person making such Alterations shall first be approved in writing by Landlord. Upon the expiration of earlier termination of this Lease, Landlord may elect to have Tenant either (i) surrender with the Premises any or all of Alterations as Landlord, Landlord shall determine (except trade fixtures not attached to the Premises), in which case, such Alterations shall become the property of Landlord, or (ii) promptly remove any or all of such Alterations designated by Landlord to be removed, in which case, Tenant shall repair and restore the Premises to its original condition as of the date of substantial completion of the Tenant Work, reasonable wear and tear excepted. (c) Tenant shall keep the Premises, the Building and the Project free from any and all liens arising out of any work performed, materials furnished, or obligations incurred by or for Tenant. In the event that Tenant shall not, within ten (10) days following the imposition of any such lien, cause the same to be released of record by payment or posting of a bond in a form and issued by a surety acceptable to Landlord, Landlord shall have the right, but not the obligation, to cause such lien to be released by such means as it shall deem proper (including payment of or defense against the claim giving rise to such lien); in such case, Tenant shall reimburse Landlord for all amounts so paid by Landlord in connection therewith, together with all of Landlord's costs and expenses, with interest thereon at the Default Rate (defined below). Such rights of Landlord shall be in addition to all other remedies provided herein or by law.
Alterations After the Commencement Date, Tenant shall not make or permit any Alterations in, on or about the Premises, except for nonstructural Alterations not exceeding Twenty-Five Thousand and no/100ths Dollars ($25,000.00) in cost during any twelve (12) month period, without the prior written consent of Landlord, which consent shall not be unreasonably withheld, and according to plans and specifications reasonably approved in writing by Landlord. Notwithstanding the foregoing, Tenant shall not, without the prior written consent of Landlord, make any (i) alterations to the exterior of the Building; (ii) alterations to and penetrations of the roof of the Building; or (iii) alterations visible from outside the Building to which Landlord may withhold Landlord's consent on wholly aesthetic grounds. All Alterations shall be installed at Tenant's sole expense, in compliance with all applicable laws and permit requirements by a licensed contractor, shall be done in a good and workmanlike manner conforming in quality and design with the Premises existing as of the Commencement Date, and shall not diminish the value of either the Building or the Premises. All Alterations made by Tenant shall be and become the property of Landlord upon installation and shall not be deemed Tenant's Personal Property; provided, however, that Landlord may, at its option, require that Tenant, at Tenant's expense, remove any or all Alterations installed by Tenant and return the Premises to their condition as of the Commencement Date of this Lease, normal wear and tear excepted and subject to the provisions of Paragraph 23. If Tenant removes any Alterations as required or permitted herein, Tenant shall repair any and all damage to the Premises caused by such removal and return the Premises to their condition as of the Commencement Date, normal wear and tear excepted and subject to the provisions of Paragraph 22. Notwithstanding any other provision of this Lease, Tenant shall be solely responsible for the maintenance and repair of any Alterations made by it to the Premises. The provisions of this Paragraph 12 shall not apply to the Tenant Improvements which shall be governed by the provisions set forth in the Work Letter Agreement attached as EXHIBIT D.
