Hazardous Materials. Tenant shall not allow, cause or permit any Hazardous Materials to be generated, used, treated, released, stored or disposed of in or about the Building or the Land, provided that Tenant may use and store normal and reasonable quantities of standard cleaning and office materials (such as, without limitation, toner, [[Unknown Identifier]] printing supplies) in the Premises so long as such materials are properly, safely and lawfully stored and used by Tenant and the quantity of same does not equal or exceed a “reportable quantity” as defined in 40 C.F.R. 302 and 305, as amended, or any applicable state or local law that requires reporting. At the expiration or earlier termination of this Lease, with respect to conditions relating to Hazardous Materials existing on account of Tenant’s use or occupancy of the Premises or any action or inaction of Tenant or any Agent respecting Hazardous Materials (it being understood that the term “inaction” as used in this Section shall not impose upon Tenant any obligation to remove Hazardous Materials existing in the Premises as of the Lease Commencement Date which were introduced into the Premises by anyone other than Tenant or any Agent, unless and to the extent such condition is knowingly aggravated as a result of Tenant’s use or occupancy of the Premises), Tenant shall surrender the Premises to Landlord free of Hazardous Materials that are in violation of Environmental Laws. Notwithstanding the termination or any other provision of this Lease, Tenant shall indemnify, defend (with counsel approved by Landlord) and hold Landlord and Landlord’s Representatives harmless from and against any and all Claims of any kind or nature, known or unknown, contingent or otherwise, which arise out of or are in any way related to the acts or omissions of Tenant or any Agent (including, but not limited to, reasonable attorneys’, consultant, laboratory and expert fees and any diminution in the value of the Building, damages for the loss or restriction on use of any space or amenity of the Building and damages arising from any adverse impact on marketing of space), whether before, during or after the Lease Term arising from or related to the generation, use, presence, transportation, storage, treatment, disposal, spill, release or discharge of Hazardous Materials by Tenant or any Agent in or about the Premises or the Building. Notwithstanding the termination or other provision of this Lease Landlord shall indemnify, defend (with counsel approved by Tenant) and hold Tenant and Tenant’s Representatives harmless from and against any and all Claims of any kind or nature which are arise out of or are in any way related to the acts or omissions of Landlord or any Landlord’s Representative (including but not limited to, reasonable attorneys’, consultant, laboratory and expert fees and damages for the loss or restriction on use of the Premises or any other space or amenity of the Building) arising from or related to the generation, use, presence, transportation, storage, treatment, disposal, spill, release or discharge or Hazardous Materials by Landlord or any Landlord’s Representative. Tenant shall: # give Landlord prompt verbal and follow-up written notice of any Environmental Default, or circumstance that could reasonably be expected to give rise to an Environmental Default, of which Tenant has actual knowledge, which Environmental Default (if arising) Tenant shall cure in accordance with all Environmental Laws and only after Tenant has obtained Landlord’s prior written consent, which shall not be unreasonably withheld, conditioned or delayed; and # promptly deliver to Landlord copies of any material written notices or other items received by Tenant from or submitted by Tenant to any governmental or quasi-governmental agency respecting Hazardous Materials, or any claim instituted or threatened in writing against Tenant by any third party, concerning Hazardous Materials and the Premises, the occupancy or use thereof as it relates to Hazardous Materials, or the existence or potential existence of Hazardous Materials therein. To the extent required by applicable Environmental Laws, Tenant covenants to promptly investigate, clean up and otherwise remediate, at Tenant’s sole cost and expense, any spill, release or discharge of Hazardous Materials at or about the Premises, the Building and/or the Land to the extent caused by the acts or omissions of Tenant or Agents. Such investigation, clean up and remediation shall be performed in accordance with applicable Environmental Laws and to the reasonable satisfaction of Landlord and only after Tenant has obtained Landlord’s written consent, such consent not to be unreasonably withheld, conditioned or delayed. Upon any Environmental Default, in addition to all other rights available to Landlord under this Lease, at law or in equity, Landlord shall have the right but not the obligation to enter the Premises, to supervise and approve any actions taken by Tenant to address the Environmental Default, and, if Tenant fails to address same with reasonable promptness in accordance with this Lease, to take such actions as may be required by applicable Environmental Law to cure the Environmental Default. If any governmental agency shall require testing to ascertain whether an Environmental Default by Tenant is pending or threatened, then, subject to Tenant’s right to contest such requirement as provided herein, Tenant shall pay the costs therefor as additional rent within thirty (30) days following Landlord’s written invoice therefor, accompanied by commercially reasonable back-up documentation for such costs. Promptly upon Landlord’s written request, Tenant shall execute from time to time affidavits, representations and similar documents concerning Tenant’s knowledge and belief regarding the presence of Hazardous Materials at or in the Premises. Landlord shall have the right but not the obligation, at all reasonable times during the Lease Term, to inspect the Premises and conduct tests and investigations and take samples to determine whether Tenant is in compliance with the provisions of this Article, and to request lists of all Hazardous Materials used or stored at the Premises. In conducting any such tests, investigations or sampling, Landlord shall use diligent efforts to minimize any interference with Tenant’s use of or access to the Premises. The cost of any such inspections, tests and investigations shall be paid by Landlord at its sole cost and expense, except that the reasonable costs of such inspections, tests and investigations shall be borne by Tenant where the same disclose that Tenant is not in compliance with the requirements of this Lease respecting Hazardous Materials in all material respects. Landlord will provide Tenant with reasonable prior notice of any such inspection in advance thereof, other than in cases of emergency where Landlord shall endeavor to provide Tenant contemporaneous telephonic or e-mail notice. At any time during the Lease Term, Landlord may, after reasonable prior written notice to Tenant, perform an environmental site assessment or environmental audit of the Premises to assess with a reasonable degree of certainty the presence or absence of any Hazardous Materials in the Premises and the potential costs in connection with abatement, cleanup, or removal of any Hazardous Materials placed within or released from the Premises by Tenant or any Agent. Tenant will reasonably cooperate with Landlord and allow Landlord and Landlord’s Representatives reasonable access to any and all parts of the Premises and to the records of Tenant with respect to the Premises and Hazardous Materials for the purpose of performing such environmental site assessment or environmental audit. In conducting any such assessment or audit, Landlord shall use diligent efforts to minimize any interference with Tenant’s use of or access to the Premises. The cost of any such assessments or audits shall be paid by Landlord at its sole cost and expense, except Tenant shall pay the cost of any such assessment or audit which indicates that Hazardous Materials have been placed in or have been released from the Premises by Tenant or any Agent in violation of the terms of this Lease.

Use of Hazardous Material. Tenant shall not cause or permit any Hazardous Material to be brought upon, kept or used in or about the Premises by Tenant, its agents, employees, contractors or invitees without the prior written consent of Landlord. If Tenant breaches the obligations stated in the preceding sentence, or if contamination of the Premises by Hazardous Material otherwise occurs unless caused by Landlord, its agents, employees, contractors, or invitees or by migration from an adjacent or nearby site through no fault of Tenant, Tenant shall indemnify, protect, defend and hold Landlord harmless from any and all claims, judgments, damages, penalties, fines, costs, liabilities or losses (including, without limitation, diminution in value of the Premises, damages for the loss or restriction on use of rentable Premises or usable space or of any amenity of the Premises, damages arising from any adverse impact on marketing of Premises space, and sums paid in settlement of claims, reasonable attorneys’ fees, consultant fees and expert fees) which arise during or after the Term as a result of such contamination. This indemnification of Landlord by Tenant includes, without limitation, costs incurred in connection with any investigation of site conditions or any clean-up, remedial, removal or restoration work required by any federal, state or local government agency or political subdivision because of Hazardous Material present in the soil, surface water or groundwater on, near or under the Premises unless such Hazardous Material was present at the beginning of this Lease, was caused by Landlord, its employees, agents, contractors or invitees, or migrated to the Premises from some adjacent or nearby site through no fault of Tenant. As used herein, the term “Hazardous Material” means any hazardous or toxic substance, material or waste, including, but not limited to, those substances, materials, and wastes listed in the United States Department of Transportation Hazardous materials Table (49 CFR 172.101) or by the Environmental Protection Agency as hazardous substances (40CFR part 302) and amendments thereto, or such substances, materials and wastes that are or become regulated under any applicable local, state or federal law. Landlord and its agents shall have the right, but not the duty, to inspect the Premises at any time to determine whether Tenant is complying with the terms of this Lease.

Prohibition Against Hazardous Material. Tenant shall not cause, or allow any of Tenant Parties to cause, any Hazardous Materials (as defined below) to be handled, used, generated, stored, released or disposed of in, on, under or about the Premises, the Building or the Project or surrounding land or environment in violation of any Applicable Laws. Tenant must obtain Landlord’s written consent prior to the introduction of any Hazardous Materials onto the Project. Notwithstanding the foregoing, Tenant may handle, store, use and dispose of products containing small quantities of Hazardous Materials for general office purposes (such as toner for copiers) to the extent customary and necessary for the Permitted Use of the Premises, the Hazardous Materials necessary for the operation and maintenance of the Emergency Generator allowed pursuant to Paragraph 41 and the Hazardous Materials necessary for the operation of a Cafeteria pursuant to Paragraph 43; provided that Tenant shall always handle, store, use, and dispose of any such Hazardous Materials in a safe and lawful manner and never allow such Hazardous Materials to contaminate the Premises, Building, or Project or surrounding land or environment. Tenant shall indemnify, defend (by counsel reasonably acceptable to Landlord), protect and hold Landlord and the Landlord Parties harmless from and against any and all Losses directly or indirectly arising out of or related to the use, generation, handling, storage, release, or disposal of Hazardous Materials by Tenant or any of Tenant Parties in, on, under or about the Premises, the Building or the Project or surrounding land or environment (even though the same may be permissible under all Applicable Laws or the provisions of this Lease), which indemnity shall include, without limitation, damages for personal or bodily injury, property damage, damage to the environment or natural resources occurring on or off the Premises, losses attributable to diminution in value or adverse effects on marketability, the cost of any investigation, monitoring, government oversight, repair, removal, remediation, restoration, abatement, and disposal, and the preparation of any closure or other required plans, whether such action is required or necessary prior to or following the expiration or earlier termination of this Lease. Neither the consent by Landlord to the use, generation, storage, release or disposal of Hazardous Materials nor the strict compliance by Tenant with all Applicable Laws pertaining to Hazardous Materials shall excuse Tenant from Tenant’s obligation of indemnification pursuant to this Paragraph 4.4.1. Tenant’s obligations pursuant to the foregoing indemnity shall survive the expiration or earlier termination of this Lease

Landlord acknowledges that it is not the intent of this Article to prohibit Tenant from operating its business for the Permitted Use. Tenant may operate its business according to the custom of Tenant’s industry so long as the use or presence of Hazardous Materials is strictly and properly monitored in accordance with Applicable Laws. As a material inducement to Landlord to allow Tenant to use Hazardous Materials in connection with its business, Tenant agrees to deliver to Landlord # a list identifying each type of Hazardous Material to be present at the Premises that is subject to regulation under any environmental Applicable Laws in the form of a Tier II form pursuant to [Section 312] of the Emergency Planning and Community Right-to-Know Act of 1986 (or any successor statute) or any other form reasonably requested by Landlord, # a list of any and all approvals or permits from Governmental Authorities required in connection with the presence of such Hazardous Material at the Premises and # correct and complete copies of # notices of violations of Applicable Laws related to Hazardous Materials and # plans relating to the installation of any storage tanks to be installed in, on, under or about the Project (provided that installation of storage tanks shall only be permitted after Landlord has given Tenant its written consent to do so, which consent Landlord may withhold in its sole and absolute discretion) and closure plans or any other documents required by any and all Governmental Authorities for any storage tanks installed in, on, under or about the Project for the closure of any such storage tanks (collectively, “Hazardous Materials Documents”). Tenant shall deliver to Landlord updated Hazardous Materials Documents, within fourteen (14) days after receipt of a written request therefor from Landlord, not more often than once per year, unless # there are any changes to the Hazardous Materials Documents or # Tenant initiates any Alterations or changes its business, in either case in a way that involves any material increase in the types or amounts of Hazardous Materials, in which case Tenant shall deliver updated Hazardous Materials documents (without Landlord having to request them) before or, if not practicable to do so before, as soon as reasonably practicable after the occurrence of the events in [Subsection 21.2(m) or (n)])]. For each type of Hazardous Material listed, the Hazardous Materials Documents shall include # the chemical name, # the material state (e.g., solid, liquid, gas or cryogen), # the concentration, # the storage amount and storage condition (e.g., in cabinets or not in cabinets), # the use amount and use condition (e.g., open use or closed use), # the location (e.g., room number or other identification) and # if known, the chemical abstract service number. Notwithstanding anything in this Section to the contrary, Tenant shall not be required to provide Landlord with any documents containing information of a proprietary nature, unless such documents contain a reference to Hazardous Materials or activities related to Hazardous Materials. Landlord may, at Landlord’s expense, cause the Hazardous Materials Documents to be reviewed by a person or firm qualified to analyze Hazardous Materials to confirm compliance with the provisions of this Lease and with Applicable Laws. In the event that a review of the Hazardous Materials Documents indicates non-compliance with this Lease or Applicable Laws, Tenant shall, at its expense, diligently take steps to bring its storage and use of Hazardous Materials into compliance. Notwithstanding anything in this Lease to the contrary or Landlord’s review into Tenant’s Hazardous Materials Documents or use or disposal of hazardous materials, however, Landlord shall not have and expressly disclaims any liability related to Tenant’s or other tenants’ use or disposal of Hazardous Materials, it being acknowledged by Tenant that Tenant is best suited to evaluate the safety and efficacy of its Hazardous Materials usage and procedures.

Prohibitions. As a material inducement to Landlord to enter into this Lease with Tenant, Tenant has fully and accurately completed Landlord’s Pre-Leasing Environmental Exposure Questionnaire (the "Environmental Questionnaire"), which is attached as Exhibit E. Tenant agrees that except for those chemicals or materials, and their respective quantities, specifically listed on the Environmental Questionnaire (as the same may be updated from time to time as provided below), neither Tenant nor Tenant’s employees, contractors and subcontractors of any tier, entities with a contractual relationship with Tenant (other than Landlord), or any entity acting as an agent or sub-agent of Tenant (collectively, "Tenant's Agents") will produce, use, store or generate any "Hazardous Materials," as that term is defined below, on, under or about the Premises, nor cause any Hazardous Material to be brought upon, placed, stored, manufactured, generated, blended, handled, recycled, used or "Released," as that term is defined below, on, in, under or about the Premises. If any information provided to Landlord by Tenant on the Environmental Questionnaire, or otherwise relating to information concerning Hazardous Materials is intentionally false, incomplete, or misleading in any material respect, the same shall be deemed a default by Tenant under this Lease. Upon Landlord's request, or in the event of any material change in Tenant's use of Hazardous Materials in the Premises, Tenant shall deliver to Landlord an updated Environmental Questionnaire at least once a year. Tenant shall notify Landlord prior to using any Hazardous Materials in the Premises not described on the initial Environmental Questionnaire, and, to the extent such use would, in Landlord's reasonable judgment, cause a material increase in the risk of liability compared to the uses previously allowed in the Premises, such additional use shall be subject to Landlord's prior consent, which may be withheld in Landlord’s reasonable discretion. Tenant shall not install or permit Tenant's Agents to install any underground storage tank on the Premises.

For purposes of this Lease, "Release" or "Released" or "Releases" shall mean any release, deposit, discharge, emission, leaking, spilling, seeping, migrating, injecting, pumping, pouring, emptying, escaping, dumping, disposing, or other movement of Hazardous Materials into the environment. Landlord acknowledges that Tenant will be installing and using fume hoods in the Premises and that emissions of Hazardous Materials into the air in compliance with all Environmental Laws shall not be considered Releases.

Releases of Hazardous Materials. If due to the acts or omissions of Tenant or Tenant's Agents, any Release of any Hazardous Material in, on, under, from or about the Premises shall occur at any time during the Lease Term and/or if due to the acts or omissions of Tenant or Tenant's Agents any other Hazardous Material condition exists at the Premises that requires response actions of any kind, in addition to notifying Landlord as specified above, Tenant, at its own sole cost and expense, shall # immediately comply with any and all reporting requirements imposed pursuant to any and all Environmental Laws, # provide a written certification to Landlord indicating that Tenant has complied with all applicable reporting requirements, # take any and all necessary investigation, corrective and remedial action in accordance with any and all applicable Environmental Laws, utilizing an environmental consultant approved by Landlord, all in accordance with the provisions and requirements of this Section 5.3, including, without limitation, [Section 5.3.4], and # take any such additional investigative, remedial and corrective actions as Landlord shall in its reasonable discretion deem necessary such that the Premises are remediated to the condition existing prior to such Release.

Notwithstanding anything to the contrary contained in Section 28 and/or this Section 30. Tenant shall not be responsible for, and the indemnification and hold harmless obligation set forth in this paragraph shall not apply to # contamination in the Premises or the Project which Tenant can prove to Landlord’s reasonable satisfaction existed in the Premises or the Project immediately prior to the date of this Lease, or # the presence of any Hazardous Materials in the Premises or the Project which Tenant can prove to Landlord’s reasonable satisfaction migrated from outside of the Premises into the Premises or outside the Project into the Project, except to the extent in either case, the presence of such Hazardous Materials # is the result of a breach by Tenant of any of its obligations under this Lease, or # was caused, contributed to or exacerbated by Tenant or any Tenant Party.
