Tenant shall be allowed to make any material structural alterations, additions or improvements to the Leased Property with the prior consent of Landlord, which consent shall not be unreasonably withheld, conditioned, or delayed and shall be deemed given if not denied in writing with specific reasons therefor within fifteen (15) days after written request therefor. Any alteration, addition or improvement made by Tenant after such consent shall be completed in a good and workmanlike manner and in accordance with all applicable codes and regulations. Except as otherwise set forth in the immediately preceding sentence, Tenant may make any other alterations, additions or improvements to the Leased Property as Tenant may elect, all at its sole cost and expense, provided that Tenant does so in a good and workmanlike manner and in accordance with all applicable codes and regulations. All alterations, additions and improvements made pursuant to this Section 9(a) shall be surrendered with the Leased Property upon the expiration or earlier termination of the Lease Term and shall thereupon become the property of Landlord without any compensation to Tenant.

Alterations: alterations, decorations, additions, installations, demolitions, improvements or other changes.

Tenant shall make no alterations, additions or improvements, other than the Tenant Improvements (which shall be subject to the Work Letter and not this Article 17, other than as expressly set forth in Section 17.7, 17.8, 17.9 and 17.12 below), in or to the Premises or engage in any construction, demolition, reconstruction, renovation or other work (whether major or minor) of any kind in, at or serving the Premises (“Alterations”) without Landlord’s prior written approval, which approval may be subject to the consent of one or more Lenders, if required under any applicable Loan Document, but which approval Landlord shall not otherwise unreasonably withhold, condition or delay; provided, however, that, in the event any proposed Alteration affects # any structural portions of the Building, including exterior walls, the roof, the foundation or slab, foundation or slab systems (including barriers and subslab systems) or the core of the Building, # the exterior of the Building or # any Building systems, including elevator, plumbing, HVAC, electrical, security, life safety and power, then Landlord may withhold its approval in its sole and absolute discretion. Tenant shall, in making any Alterations, use only those architects, contractors, suppliers and mechanics of which Landlord has given prior written approval, which approval shall not be unreasonably withheld, conditioned or delayed. In seeking Landlord’s approval, Tenant shall prepare and provide to Landlord for approval schematics and a general plan covering the Alterations (the “Draft Development Plans”), which shall contain sufficient information and detail concerning the nature and cost of such Alterations as Landlord may reasonably request; provided that Tenant shall not commence any such Alterations that require Landlord’s consent unless and until Tenant has received the written approval of Landlord and any and all Lenders whose consent is required under any applicable Loan Document. Landlord shall notify Tenant in writing within seven (7) business days after receipt of the Draft Development Plans whether Landlord approves or objects to the Draft Development Plans and of the manner, if any, in which the Draft Development Plans are unacceptable. Landlord’s failure to respond within such seven (7) business day period shall be deemed an approval by Landlord. If Landlord reasonably objects to the Draft Development Plans, then Tenant shall not proceed with the proposed Alterations unless Tenant revises the Draft Development Plans and causes Landlord’s objections to be remedied in the revised Draft Development Plans. Tenant shall then resubmit the revised Draft Development Plans to Landlord for approval. Landlord’s approval of or objection to revised Draft Development Plans and Tenant’s correction of the same shall be in accordance with this Section until Landlord has approved the Draft Development Plans in writing or been deemed to have approved them. The iteration of the Draft Development Plans that is approved or deemed approved by Landlord without objection shall be referred to herein as the “Approved Development Plans.” Tenant shall not proceed with the proposed Alteration unless Tenant then prepares final plans and specifications for the Alteration that are consistent with and are logical evolutions of the Approved Development Plans, including, without limitation, plans, specifications, bid proposals, certified stamped engineering drawings and calculations by Tenant’s engineer of record or architect of record (including connections to the Building’s structural system, modifications to the Building’s envelope, non-structural penetrations in slabs or walls, and modifications or tie-ins to life safety systems), work contracts, requests for laydown areas and such other information concerning the nature and cost of the Alterations as Landlord may reasonably request,. As soon as such final plans and specifications (“Alteration Plans”) are completed, Tenant shall deliver the same to Landlord for Landlord’s approval, which approval shall not be unreasonably withheld, conditioned or delayed; provided that Tenant shall not commence any such Alterations that require Landlord’s consent unless and until Tenant has received the written approval of Landlord of the Alteration Plans and any and all Lenders whose consent is required under any applicable Loan Document. In no event shall Tenant use or Landlord be required to approve any architects, consultants, contractors, subcontractors or material suppliers that Landlord reasonably believes could cause labor disharmony or may not have sufficient experience, in Landlord’s reasonable opinion, to perform work in an occupied Class “A” laboratory research building and in tenant-occupied lab areas.

Alterations. Other than any alterations which constitute the Project, ​’s prior approval shall be required in connection with any alterations to any Improvements # that could reasonably be expected to have a Material Adverse Effect, # the cost of which (including any related alteration, improvement or replacement) is reasonably anticipated to exceed the Alteration Threshold, # that are structural in nature, which approval may be granted or withheld in ​’s reasonable discretion, or # made during the continuance of an Event of Default (any of the foregoing, a “Material Alteration”). If the total unpaid amounts incurred and to be incurred with respect to any alterations to the Improvements from and after Completion of the Project shall at any time exceed the Alteration Threshold (unless the cost of such Material Alteration is eligible for disbursement from the Replacement Reserve Account, in which case ​ shall be given a credit for amounts on deposit in the Replacement Reserve Account), ​ shall promptly deliver to ​ as security for the payment of such amounts and as additional security for ​’s obligations under the Loan Documents any of the following: # cash, # a Letter of Credit acceptable to ​, # securities acceptable to ​, or # a completion bond acceptable to ​. Such security shall be in an amount equal to one hundred twenty-five percent (125%) of the excess of the total unpaid amounts incurred and to be incurred with respect to such alterations to the Improvements over the Alteration Threshold (such security, the “Alterations Security”). Upon substantial completion of any Material Alteration, # ​ shall provide evidence satisfactory to ​ that # the Material Alteration was constructed in accordance with applicable Legal Requirements, # all contractors, subcontractors, materialmen and professionals who provided work, materials or services in connection with the Material Alteration have been paid in full and have delivered unconditional releases of liens, and # all material licenses and permits necessary for the use, operation and occupancy of the Material Alteration (other than those which depend on the performance of tenant improvement work) have been issued and # provided no Event of Default is then continuing, any remaining Alterations Security shall be promptly returned to ​. Prior to substantial completion of any Material Alteration, to the extent the Alterations Security shall exceed one hundred twenty-five percent (125%) of the excess of the total unpaid amounts incurred and to be incurred with respect to any such Material Alteration, ​ shall be entitled to a release of such excess Alterations Security (e.g., the amount by which such Alterations Security exceeds one hundred twenty-five percent (125%) of the excess of the total unpaid amounts incurred and to be incurred with respect to any such Material Alteration) in accordance with [Section 7.4.2] hereof, applied mutatis mutandis.

LESSEE shall move its furniture, furnishings, equipment, inventory, and other property as required by LESSOR to enable LESSOR to carry out the above-described work.

None of the Borrowers shall alter or cause or permit the alteration of any Improvements at any Property without the Agent’s prior Approval; provided, however, that if no Default has occurred and remains outstanding and if no Event of Default has occurred, such Approval shall not be unreasonably withheld, conditioned or delayed in connection with any alteration that # is not reasonably likely to result in a Material Adverse Change or an adverse effect of a material nature on the Net Cash Flow from the relevant Property, # complies with all Legal Requirements, including without limitation, Legal Requirements regarding environmental matters, landmarks and zoning, # is not reasonably likely to affect any structural component of the Improvements or the exterior of any building constituting a part of any Improvements or materially affect any utility or HVAC system contained in any Improvements, # have an aggregate cost, for all alterations pending or being actively pursued in respect of a Property at any time, of less than SEVEN HUNDRED FIFTY THOUSAND DOLLARS AND ZERO CENTS ($750,000.00) and # have an aggregate cost, with respect to all the Properties undergoing alterations at any time, of less than five percent (5%) of the Outstanding Principal Balance (each of clauses (D) and (E), a “Major Alteration Threshold”). For the avoidance of doubt, the Agent may require that the Borrowers deliver additional security to the Agent for the Borrowers’ obligations under the Loan Documents as a condition to the Agent’s approval of any alteration that would exceed either Major Alteration Threshold.
