If Landlord determines at any time that changes in the Final TI Working Drawings or in any other aspect of the Approved TI Plans relating to any item of Landlord's TI Work are required as a result of applicable law or governmental requirements, or are required as a result of unanticipated conditions encountered in the course of construction, then Landlord shall promptly # advise Tenant of such circumstances and # at Tenant's sole cost and expense, subject to Landlord's payment of the Tenant Improvement Allowance and, to the extent requested by Tenant, the Additional TI Allowance, cause revised Final TI Working Drawings to be prepared by the Architect and submitted to Tenant, for Tenant's approval, which shall not be unreasonably withheld. Failure of Tenant to deliver to Landlord written notice of disapproval and specification of such required changes on or before any deadline reasonably specified by Landlord (which shall not be less than three (3) business days after delivery thereof to Tenant) shall constitute and be deemed to be a Tenant Delay to the extent Landlord is delayed in completing Landlord’s TI Work.

If Tenant at any time desires any changes, alterations or additions to the Final TI Working Drawings, Tenant shall submit a detailed written request to Landlord specifying such changes, alterations or additions (a "Tenant Change Request"). Upon receipt of any such request, Landlord, within five (5) business days, shall promptly notify Tenant of # whether the matters proposed in the Tenant Change Request are approved by Landlord (which approval shall not be unreasonably withheld, conditioned or delayed by Landlord), # Landlord's estimate of the number of days of delay, if any, which shall be caused in the construction of the Tenant Improvements by such Tenant Change Request if implemented (including, without limitation, delays due to the need to obtain any revised plans or drawings and any governmental approvals), and # Landlord's estimate of the increase, if any, which shall occur in the cost of design, permitting, project management and construction of the Tenant Improvements affected by such Tenant Change Request if such Tenant Change Request is implemented (including, but not limited to, any costs of compliance with laws or governmental regulations that become applicable because of the implementation of the Tenant Change Request). If Landlord approves the Tenant Change Request and Tenant notifies Landlord in writing, within three (3) business days after receipt of such notice from Landlord, of Tenant's approval of the Tenant Change Request (including the estimated delays and cost increases, if any, described in Landlord's notice), then Landlord shall cause such Tenant Change Request to be implemented and Tenant shall be responsible for all actual costs or cost increases resulting from or attributable to the implementation of the Tenant Change Request, and any delays resulting therefrom shall be deemed to be a Tenant Delay (subject to Landlord's payment of the Tenant Improvement Allowance and, to the extent requested by Tenant, the Additional TI Allowance). If Tenant fails to notify Landlord in writing of Tenant's approval of such Tenant Change Request within said three (3) business day period, then such Tenant Change Request shall be deemed to be withdrawn and shall be of no further effect.

Modifications to Approved TI Construction Drawings. No material changes or modifications to the Approved TI Construction Drawings shall be made without the prior written consent of Landlord, which consent shall not be unreasonably withheld. Landlord shall have five (5) Business Days to review and notify Tenant of Landlord’s approval or disapproval of such proposed changes or modifications. Landlord will not unreasonably withhold its approval of # any request by Tenant to amend or change the Approved TI Construction Drawings, or # any change or amendment to the Approved TI Construction Drawings that may be necessary to obtain any Permits or which may be required by city officials or inspectors to comply with code rulings or interpretations (any of the foregoing, a “Plan Modification”). Without limiting the generality of the foregoing, however, Tenant acknowledges that it shall not be unreasonable for Landlord to withhold consent to any Plan Modification if any one of the circumstances listed in [clauses (a) through (c) of Section 2.2.1] of this Agreement apply. If Landlord disapproves of any Plan Modification, Landlord shall return the same to Tenant with a statement of Landlord’s reasons for disapproval, or specifying any required corrections. This procedure shall be repeated until Landlord approves the Plan Modification.

Final Working Drawings. After the Preliminary Plans have been approved by Landlord, Tenant shall cause Tenant’s Architect and the Engineers to prepare and submit for Landlord’s approval complete and detailed construction plans and specifications, including a fully coordinated set of architectural, structural, mechanical, fire protection, electrical and plumbing working drawings for the Tenant Improvement Work, in a form that is sufficiently complete to permit subcontractors to bid on the work, obtain all required Permits (as defined in [Section 3.4], below) and commence construction (the “Final Working Drawings”). The Tenant Improvements shall be designed in accordance with the LEED Design/Operational Requirements and the Final Working Drawings shall incorporate the LEED Design/Operational Requirements. Tenant shall furnish Landlord with two (2) hard copies signed by Tenant and one (1) electronic version of such Final Working Drawings. Landlord shall approve or disapprove the Final Working Drawings by giving written notice to Tenant within fifteen (15) Business Days after receipt thereof. Landlord shall not unreasonably withhold its approval of the Final Working Drawings, provided that, without limiting the generality of the foregoing, Landlord shall be entitled to withhold its consent to the Final Working Drawings for any of the reasons specified in [Section 2.2.1] above, or if in Landlord’s good faith judgment, the Final Working Drawings are inconsistent with, or do not conform to, the Approved Preliminary Plans. If Landlord disapproves the Final Working Drawings, Landlord shall return the Final Working Drawings to Tenant with a statement of Landlord’s reasons for disapproval and/or specifying any required corrections or revisions. Landlord shall approve or disapprove of any such revisions to the Final Working Drawings within seven (7) Business Days after receipt of such revisions. This procedure shall be repeated until Landlord approves the Final Working Drawings (as so approved, the “Approved TI Construction Drawings”). Tenant shall include provisions in it Design Professional Agreements (as defined in [Section 2.2.4]) which expressly allow Landlord to use any and all of the Approved TI Construction Drawings for the Tenant Improvements without any additional cost or payment if the Lease is terminated, subject to Landlord agreeing to indemnify Tenant’s Architect and Engineers in question if Landlord elects to use any of the Approved TI Construction Drawings without retaining Tenant’s Architect or Engineer for the portion of Tenant’s Work covered by the Design Profession Agreement in question.
