Alterations Section 3.1 Tenant shall not make any Alterations without Landlord’s prior written consent in each instance, provided that Tenant’s changing of wall coverings, carpeting or paint shall not be deemed to be Alterations requiring such consent. Landlord’s consent shall be granted or denied in Landlord’s sole discretion; provided, however, that Landlord shall not unreasonably withhold its consent to Alterations proposed to be made by Tenant to adapt the Premises for the Permitted Use provided that such Alterations (a) are non-structural and do not affect the Building Systems or services, (b) are performed only by contractors approved in writing by Landlord, (c) do not affect any part of the Building other than the Premises, (d) do not adversely affect any service required to be furnished by Landlord to Tenant or to any other tenant or occupant of the Building, and (e) do not reduce the value or utility of the Building. Section 3.2 (a) Prior to making any Alterations, Tenant shall (i) submit to Landlord, for Landlord’s written approval, detailed plans and specifications therefor in form satisfactory to Landlord, (ii) if such Alterations require a filing with Governmental Authority or require the consent of such authority, then such plans and specifications shall (A) be prepared and certified by a registered architect or licensed engineer, and (B) comply with all Legal Requirements to the extent necessary for such governmental filing or consent, (iii) at its expense, obtain all required permits, approvals and certificates, (iv) furnish to Landlord duplicate original policies or certificates of worker’s compensation (covering all persons to be employed by Tenant, and all contractors and subcontractors supplying materials or performing work in connection with such Alterations) and comprehensive public liability (including property damage coverage) insurance and Builder’s Risk coverage (issued on a completed value basis) all in such form, with such companies, for such periods and in such amounts as Landlord may require, naming Landlord and its employees and agents, and any Lessor and any Mortgagee as additional insureds, and (v) with respect to any Alteration costing more than $100,000.00 to complete, furnish to Landlord payment and performance bonds or such other evidence of Tenant’s ability to complete and to fully and completely pay for such Alteration as is satisfactory to Landlord; provided, however, that so long as either Global Crossing Holdings, Ltd. or Successor shall be the Guarantor under this Lease, Tenant shall not be required to furnish bonds or other security to Landlord in connection with Alterations. All Alterations shall be performed by Tenant at Tenant’s expense (A) in a good and workmanlike manner using new materials of first class quality, (B) in compliance with all Legal Requirements, and (C) in accordance with the plans and specifications previously approved by Landlord. Tenant shall at its cost and expense obtain all approvals, consents and permits from every Governmental Authority having or claiming jurisdiction prior to, during and upon completion of such Alterations. Tenant shall promptly reimburse Landlord, as Additional Rent and upon demand, for any and all actual, reasonable out-of-pocket costs and expenses incurred by Landlord in connection with Landlord’s review of Tenant’s plans and specifications for any such Alteration.
