The initial monthly installment of Base Rent amount was calculated by multiplying the initial monthly Base Rent per rentable square foot amount by the number of rentable square feet of space in the Premises, and the Annual Base Rent amount was calculated by multiplying the initial monthly installment of Base Rent amount by twelve (12). In all subsequent Base Rent payment periods during the Lease Term commencing on the first anniversary of the Rent Commencement Date, the calculation of each monthly installment of Base Rent amount reflects an annual increase of three percent (3%) and each Annual Base Rent amount was calculated by multiplying the corresponding monthly installment of Base Rent amount by twelve (12).

**	The amounts identified in the column entitled “Annual Rental Rate per Rentable Square Foot” are rounded amounts provided for information purposes only.

***

Month 1 shall begin on the Rent Commencement Date (provided that if the Rent Commencement Date does not occur on the first day of a calendar month, then Month 1 shall mean the partial month in which the Rent Commencement Date occurs plus the following full calendar month). For the avoidance of doubt, there is no Base Rent due from the period beginning on the Commencement Date and end on the Rent Commencement Date.

****	Expressed on an annualized basis even though the applicable period may be longer or shorter than twelve (12) months.

11.	Brokers (Section 24.25):	Xxxxxxx & Wakefield U.S., Inc. representing Landlord, and CBRE, Inc. representing Tenant.

12.

Expense; plus (ii) Tenant’s Share of Tax Expense; plus (iii) Tenant’s Share of Utilities Costs. Payments for any fractional calendar month or period shall be prorated.

4.3.2 Statement of Actual Operating Expenses, Tax Expenses and Utilities Costs and Payment by Tenant. Landlord shall provide Tenant on or before the first (1^st) day of June following the end of each Expense Year, a statement (the “Statement”) which shall state the Operating Expenses, Tax Expenses and Utilities Costs incurred or accrued for such preceding Expense Year, together with the calculation and reasonable breakdown and detail thereof (including invoices and paid receipts for all material line items), together with a calculation of the amount remaining due or overpaid after deduction of Estimated Expenses paid during the year. Within thirty (30) days after Tenant’s receipt of the Statement for each Expense Year ending during the Lease Term, Tenant shall pay to Landlord the full amount of the Tenant’s Share of Operating Expenses, Tax Expenses and Utilities Costs for such Expense Year, less the amounts, if any, paid during such Expense Year as the Estimated Expenses as defined in and pursuant to Section 4.3.3 below. If any Statement reflects that Tenant has overpaid Tenant’s Share of Operating Expenses and/or Tenant’s Share of Tax Expenses and/or Tenant’s Share of Utilities Costs for such Expense Year, then Landlord shall, at Landlord’s option, either (i) remit such overpayment to Tenant within thirty (30) days after such applicable Statement is delivered to Tenant, or (ii) if the Lease Term has not ended, credit such overpayment toward the additional Rent next due and payable to Tenant under this Lease. The failure of Landlord to timely furnish the Statement for any Expense Year shall not prejudice Landlord from enforcing its rights under this Article 4; provided, however, Landlord shall have no right to include in any Statement or collect from Tenant any amounts not billed within eighteen (18) months after the occurrence of the same (“Cutoff Date”), except that Tenant shall be responsible for Tenant’s Share of any Utilities Costs and Tax Expenses levied by any governmental authority or by any public utility company at any time following the applicable Cutoff Date which are attributable to any calendar year (or portion thereof) occurring prior to such Cutoff Date and within the Lease Term, so long as Landlord delivers to Tenant a xxxx and supplemental statement for such amounts within thirty (30) days following Landlord’s receipt of the applicable xxxx therefor, in which case Tenant shall have the same right to review and contest such expenses as would have applied if they had been included in the Statement for the period to which they relate, on the same conditions applicable thereto. Even though the Lease Term has expired and Tenant has vacated the Premises, if the Statement for the Expense Year in which this Lease terminates reflects that Tenant has overpaid and/or underpaid Tenant’s Share of the

Operating Expenses and/or Tenant’s Share of Tax Expenses and/or Tenant’s Share of Utilities Costs for such Expense Year, then within thirty (30) days after Landlord’s delivery of such Statement to Tenant, Landlord shall refund to Tenant any such overpayment, or Tenant shall pay to Landlord any such underpayment, as the case may be. Tenant’s failure to object any Statement within one hundred twenty (120) days after Tenant’s receipt thereof shall constitute Tenant’s irrevocable waiver to object to the same. The provisions of this Section 4.3.2 shall survive the expiration or earlier termination of the Lease Term.

4.3.3 Statement of Estimated Operating Expenses, Tax Expenses and Utilities Costs. Landlord shall endeavor to give Tenant a yearly expense estimate statement (the “Estimate Statement”) which shall set forth Landlord’s reasonable estimate (the “Estimate”) of the total amount of Tenant’s Share of the Operating Expenses, Tax Expenses and Utilities Costs for the then-current Expense Year shall be, and which shall indicate therein Tenant’s Share thereof (the “Estimated Expenses”), the monthly payment on account of Estimated Expenses (and any make-whole payments then due pursuant to the following provisions of this Section 4.3.3), and Landlord’s reasonably backup calculations for such Estimated Expenses. The failure of Landlord to timely furnish the Estimate Statement for any Expense Year shall not preclude Landlord from enforcing its rights to collect any Estimated Expenses under this Article 4. Following Landlord’s delivery of the Estimate Statement for the then-current Expense Year, Tenant shall pay, with its next installment of Base Rent due falling at least thirty (30) days after the Estimate Statement, a fraction of the Estimated Expenses for the then-current Expense Year (reduced by any amounts paid pursuant to the last sentence of this Section 4.3.3). Such fraction shall have as its numerator the number of months which have elapsed in such current Expense Year to the month of such payment, both months inclusive, and shall have twelve (12) as its denominator. Until thirty (30) days after a new Estimate Statement is furnished, Tenant shall pay monthly, with the monthly Base Rent installments, an amount equal to one-twelfth (1/12) of the total Estimated Expenses set forth in the previous Estimate Statement delivered by Landlord to Tenant.

4.4 Taxes and Other Charges for Which Tenant Is Directly Responsible. Tenant shall reimburse Landlord thirty (30) days following demand for all taxes or assessments required to be paid by Landlord (except to the extent included in Tax Expenses by Landlord), excluding state, local and federal personal or corporate income taxes measured by the net income of Landlord from all sources and estate and inheritance taxes, whether or not now customary or within the contemplation of the parties hereto, when:

4.4.1 said taxes are measured by or reasonably attributable to the cost or value of Tenant’s equipment, furniture, fixtures and other personal property located in the Premises, or by the cost or value of any leasehold improvements made in or to the Premises by or for Tenant, to the extent the cost or value of such leasehold improvements exceeds the cost or value of a building standard build-out as determined by Landlord regardless of whether title to such improvements shall be vested in Tenant or Landlord;

4.4.2 said taxes are assessed upon or with respect to the possession, leasing, operation, management, maintenance, alteration, repair, use or occupancy by Tenant of the Premises or any portion of the Project and are not otherwise excluded in this Lease (including by Section 4.2.5.2 of this Lease); or

4.4.3 said taxes are assessed upon this transaction or any document to which Tenant is a party creating or transferring an interest or an estate in the Premises to Tenant.

4.5 Late Charges. If any installment of Rent or any other sum due from Tenant shall not be received by Landlord or Landlord’s designee by the due date therefor, then Tenant shall pay to Landlord a late charge equal to five percent (5%) of the amount due; provided there shall not be any late charge imposed for the first late payment of Rent or other sum in any twelve (12) month period. The late charge shall be deemed Additional Rent and the right to require it shall be in addition to all of Landlord’s other rights and remedies hereunder, at law and/or in equity and shall not be construed as liquidated damages or as limiting Landlord’s remedies in any manner. In addition to the late charge described above, any Rent or other amounts owing hereunder which are not paid by the date that they are due shall thereafter bear interest until paid at a rate (the “Interest Rate”) equal to the lesser of (i) the “Prime Rate” or “Reference Rate” announced from time to time by the Bank of America (or such reasonable comparable national banking institution as selected by Landlord in the event Bank of America ceases to exist or publish a Prime Rate or Reference Rate), plus three percent (3%), or (ii) the highest rate permitted by applicable law.

4.6 Audit Rights. Tenant shall have the right, at Tenant’s cost, after reasonable notice to Landlord, to have Tenant’s authorized employees, consultants, agents, or third-party accountant (meeting the qualifications of an Accountant (as defined below)) inspect, , Landlord’s books, records and supporting documents concerning the Operating Expenses, Tax Expenses and Utilities Costs set forth in any Statement delivered by Landlord to Tenant for a particular Expense Year pursuant to Section 4.3.2 above (and Landlord agrees to make such books, records and supporting documentation available to Tenant and Tenant’s authorized employees, consultants, agents, or third-party accountants in electronic format); provided, however, Tenant shall have no right to conduct such inspection or object to or otherwise dispute the amount of the Operating Expenses, Tax Expenses and Utilities Costs set forth in any such Statement, unless Tenant notifies Landlord of such inspection request within six (6) months following Landlord’s delivery of a Statement, and completes the audit and makes any objection or dispute within six (6) months thereafter (the “Review Period”) (subject to reasonable extension in the event that Landlord fails to promptly upon request make available to Tenant and its authorized employees, agents, or accountants any information or materials relevant to the inspection); provided, further, that notwithstanding any such timely inspection, objection, dispute, and/or audit, and as a condition precedent to Tenant’s exercise of its right of inspection, objection, dispute, and/or audit as set forth in this Section 4.6, Tenant shall not be permitted to withhold payment of, and Tenant shall timely pay to Landlord, the full amounts as required by the provisions of this Article 4 in accordance with such Statement. However, such payment may be made under protest pending the outcome of any audit. In connection with any such inspection by Tenant, Landlord and Tenant shall reasonably cooperate with each other so that such inspection can be performed pursuant to a mutually acceptable schedule, in an expeditious manner and without undue interference with Landlord’s operation and management of the Project. If after such inspection and/or request for documentation, Tenant disputes the amount of the Operating Expenses, Tax Expenses and Utilities Costs set forth in the Statement, Tenant shall have the right, but not the obligation, within the Review Period, to cause an independent certified public accountant which is not paid on a contingency basis and which is

mutually approved by Landlord and Tenant (the “Accountant”) to complete an audit of Landlord’s books and records to determine the proper amount of the Operating Expenses, Tax Expenses and Utilities Costs incurred and amounts payable by Tenant for the Expense Year which is the subject of such Statement; provided that the Review Period shall be extended until the Accountant is selected and completes its audit. Such audit by the Accountant shall be final and binding upon Landlord and Tenant. If Landlord and Tenant cannot mutually agree as to the identity of the Accountant within thirty (30) days after Tenant notifies Landlord that Tenant desires an audit to be performed, then the Accountant shall be one of the “Big 4” accounting firms selected by Landlord, which is not paid on a contingency basis and is not, and has not been, otherwise employed or retained by Landlord or its affiliates. If such audit reveals that Landlord has over-charged Tenant, then within thirty (30) days after the results of such audit are made available to Landlord, Landlord shall reimburse to Tenant the amount of such over-charge. If the audit reveals that the Tenant was under-charged, then within thirty (30) days after the results of such audit are made available to Tenant, Tenant shall reimburse to Landlord the amount of such under-charge. Tenant agrees to pay the cost of such audit unless it is determined that Landlord’s original Statement which was the subject of such audit was overstated by five percent (5%) or more (in which case Landlord shall pay all third-party costs incurred in connection with Tenant’s inspect and audit, including, without limitation, the cost of the Accountant). The payment by Tenant of any amounts pursuant to this Article 4 shall not preclude Tenant from questioning the correctness of any Statement provided by Landlord at any time during the Review Period, but the failure of Tenant to object thereto, conduct and complete its inspection and have the Accountant conduct and complete the audit as described above prior to the expiration of the Review Period (as the same may be extended as provided herein) shall be conclusively deemed Tenant’s approval of the Statement in question and the amount of Operating Expenses, Tax Expenses and Utilities Costs shown thereon. In connection with any inspection and/or audit conducted by Tenant pursuant to this Section 4.6, Tenant agrees to keep, and to cause all of Tenant’s employees, consultants, agents, and thirty-party accountants and the Accountant to keep, all of Landlord’s books and records and the audit, and all information pertaining thereto and the results thereof, strictly confidential, and in connection therewith, Tenant shall cause such employees, consultants, agents, and thirty-party accountants and the Accountant to execute such reasonable confidentiality agreements as Landlord may require prior to conducting any such inspections and/or audits.

Tenant shall comply with the Rules and Regulations and all recorded covenants, conditions, and restrictions, now or hereafter affecting the Project, as the same may be amended, amended and restated, supplemented or otherwise modified from time to time; provided that any such amendments, restatements, supplements or modifications shall not modify Tenant’s rights or obligations hereunder or use or enjoyment of the Premises, in more than a de minimis manner. Landlord shall not enter into any new covenants, conditions, restrictions, ground leases or underlying leases, which have the effect of adversely modifying Tenant’s rights or obligations hereunder or adversely affecting Tenant’s use or enjoyment of, or access to, the Premises to more than a de minimis extent.

(d) “Release” shall mean with respect to any Hazardous Materials, any release, deposit, discharge, emission, leaking, pumping, leaching, spilling, seeping, migrating, injecting, pumping, pouring, emptying, escaping, dumping, disposing or other movement of Hazardous Materials.

5.2.2 Tenant’s Obligations – Environmental Permits. Tenant will (i) obtain and maintain in full force and effect all applicable Environmental Permits that may be required from time to time under any applicable Environmental Laws applicable to Tenant or Tenant’s use of the Premises and (ii) be and remain in compliance with all terms and conditions of all such applicable Environmental Permits and with all other limitations, restrictions, conditions, standards, prohibitions, requirements, obligations, schedules and timetables contained in all Environmental Laws applicable to Tenant or Tenant’s use of the Premises.

5.2.3 Tenant’s Obligations – Hazardous Materials. Landlord acknowledges that it is not the intent of this Section 5.2 to prohibit Tenant from operating its business for the Permitted Uses. 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 Environmental 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 prior to the Lease Commencement Date a list identifying each type of Hazardous Material that Tenant anticipates will be brought upon, kept, used, stored, handled, treated, generated on, or released or disposed of from, the Premises by Tenant and setting forth any and all governmental approvals or permits required in connection with the presence of such Hazardous Material at the Premises (the “Hazardous Materials List”).

Notwithstanding the provisions of Article 14, if any proposed transferee, assignee or sublessee is subject to a material enforcement order (considered in light of the size and stature of the entity) issued by any governmental authority in connection with the use, disposal or storage of Hazardous Materials, then Landlord it shall not be unreasonable for Landlord to withhold its consent to any proposed transfer, assignment or subletting (with respect to any such matter involving a proposed transferee, assignee or sublessee).

5.2.4 Landlord’s Right to Conduct Environmental Assessment. Landlord, subject to Section 22, shall have the right to conduct an environmental assessment of the Premises as well as any other areas in, on or about the Project that Landlord reasonably believes may have been affected adversely by Tenant’s use of the Premises (collectively, the “Affected Areas”) in order to confirm that the Premises and the Affected Areas do not contain any Hazardous Materials resulting from Tenant’s use in violation of applicable Environmental Laws or under conditions constituting or likely to constitute a Release of Hazardous Materials. Such environmental assessment shall be a so-called “Phase I” assessment or such other level of investigation which shall be the standard of diligence in the purchase or lease of similar property at the time, together with, any additional investigation and report which would customarily follow any discovery contained in such initial Phase I assessment (including, but not limited to, any so-called “Phase II” report). Such right to conduct such environmental assessment shall not be exercised more than once per calendar year unless Tenant is in default under this Section 5.2. If contamination has occurred for which Tenant is liable for under this Lease, then Tenant shall pay all reasonable out-of-pocket costs incurred to conduct the assessment. If no such contamination is found, Landlord shall pay for the costs of the assessment. Landlord shall provide Tenant with a copy of all third-party reports and tests of the Premises and Affected Areas made by or on behalf of Landlord during the Term.

5.2.5 Tenant’s Obligations to perform Corrective Action.

Landlord may engage a licensed site professional at Tenant’s sole cost and expense. Any Corrective Action to be performed by Tenant in accordance with this Section 5.2.5 will be performed with Landlord’s prior written approval and in accordance with applicable Environmental Laws, at Tenant’s sole cost and expense and by an environmental consulting firm and licensed site professional (all reasonably acceptable to Landlord and Tenant). Notwithstanding any other provision of this Lease, a Corrective Action shall only include the imposition of an Activity and Use Limitation pursuant to the Massachusetts Contingency Plan that permits office and laboratory uses.

remedies under this Lease, at law and/or in equity), to provide access to the Premises, the Building and the Project as may be requested by Tenant, the licensed site professional overseeing the Corrective Action and any other consultants to accomplish the Corrective Action. Tenant or its consultant may install, inspect, maintain, replace and operate remediation equipment and conduct the Corrective Action as it considers necessary, subject to Landlord’s approval. Tenant and Landlord shall, in good faith, cooperate with each other with respect to any Corrective Action after the expiration or earlier termination of this Lease so as not to interfere unreasonably with the conduct of Landlord’s or any third party’s business on the Premises, the Building and the Project. Landlord may, in its sole discretion, provide access until Tenant delivers evidence reasonably satisfactory to Landlord that Tenant’s Corrective Action activities on the Premises and the Affected Areas satisfy applicable Environmental Laws. It shall be reasonable for Landlord to require Tenant to deliver all such reports prepared by the licensed site professional and filings with applicable governmental agencies indicating that no further Corrective Action is needed under any applicable laws and regulations, including without limitation the Massachusetts Contingency Plan. Landlord may, in its sole discretion, continue to provide access until such time as Landlord is able to use the Premises and the Affected Areas for office and laboratory purposes. If Landlord desires to situate a tenant in the Premises, the Building and the Project and remediation of the Premises and the Affected Areas is ongoing in a manner that prevents Landlord from leasing such space, then Landlord shall provide Tenant with access to complete the remediation and Tenant shall be obligated to continue paying a market rental rate for the portion of the Building that cannot be leased due to the remediation performed by Tenant until Tenant completes the remediation preventing the leasing. Tenant agrees to install, at Tenant’s sole cost and expense, screening around its remediation equipment so as to protect the aesthetic appeal of the Premises, the Building and the Project. Tenant also agrees to use reasonable efforts to locate its remediation and/or monitoring equipment, if any (subject to the requirements of Tenant’s consultant and governmental agencies with jurisdiction over the Premises, the Building and the Project) in a location which will allow Landlord, to the extent reasonably practicable, the ability to lease the Premises, the Building and the Project to a subsequent user. Notwithstanding anything above to the contrary, if any clean-up or monitoring procedure is required by any applicable governmental authorities in, on, under or about the Premises and the Affected Areas during the Lease Term as a consequence of any Hazardous Materials contamination actually caused by Tenant and the procedure for clean-up is not completed (to the satisfaction of the governmental authorities) prior to the expiration or earlier termination of this Lease and the same prevents the occupancy of the Building then, at Landlord’s election, (i) this Lease shall be deemed renewed with respect to the portion of the Building that cannot be occupied for a term commencing on the expiration or earlier termination of this Lease and ending on the date the clean-up procedure preventing the occupancy is anticipated to be completed; or (ii) Tenant shall be deemed to have impermissibly held over with respect to the portion of the Building that cannot be occupied (and Article 16 of this Lease shall apply with full force and effect) and Landlord shall be entitled to all damages directly or indirectly incurred, including, without limitation, damages occasioned by the inability to relet with respect to the portion of the Building that cannot be occupied or a reduction of the fair market or rental value of the Premises and/or the Building.

5.2.6 Tenant’s Duty to Notify Landlord Regarding Releases. Tenant agrees to promptly notify Landlord of any Release of Hazardous Materials in the Premises, the Building or any other portion of the Project which Tenant becomes aware of during the Term of this Lease, whether caused by Tenant or any other persons or entities. In the event of any Release of Hazardous Materials caused by Tenant or any of Tenant’s Parties, Landlord shall have the right, but not the obligation, to cause Tenant, at Tenant’s sole cost and expense, to immediately take all reasonable steps Landlord reasonably deems necessary or appropriate to remediate such Release to a condition required for office and laboratory use. Tenant will, upon the request of Landlord at any time during which Landlord has actual reason to believe that Tenant is not in compliance with this Section 5.2 (and in any event no earlier than sixty (60) days and no later than thirty (30) days prior to the expiration of this Lease), cause to be performed an environmental audit of the Premises at Tenant’s expense by an established environmental consulting firm reasonably acceptable to Landlord. In the event the audit provides that Corrective Action is required then Tenant shall immediately perform the same at its sole cost and expense.

5.2.7 Tenant’s Environmental Indemnity. To the fullest extent permitted by law, Tenant agrees to promptly indemnify, protect, defend and hold harmless Landlord and Landlord’s members, partners, subpartners, independent contractors, officers, directors, shareholders, employees, agents, successors and assigns (collectively, “Landlord Parties”) from and against any and all claims, damages, judgments, suits, causes of action, losses,

Tenant’s obligations hereunder shall include, without limitation, and whether

foreseeable or unforeseeable, all costs of any required or necessary repair, cleanup or detoxification or decontamination of the Premises, the Building and/or the Project, or the preparation and implementation of any closure, remedial action or other required plans in connection therewith to return the Premises, the Building and/or the Project to the condition permitting office and lab use. The provisions of this Section 5.2.7 will survive the expiration or earlier termination of this Lease.

5.2.8 Tenant Representation and Warranty. Tenant hereby represents and warrants to Landlord that as of the date hereof (i) Tenant has not been required by any prior landlord, lender or governmental authority at any time to take remedial action in connection with Hazardous Materials contaminating a property which contamination was permitted by Tenant or resulted from Tenant’s action or use of the property in question, and (ii) Tenant is not subject to any enforcement order issued by any governmental authority in connection with the use, storage, handling, treatment, generation, release or disposal of Hazardous Materials (including, without limitation, any order related to the failure to make a required reporting to any governmental authority).

5.2.9 Limitations on Tenant’s Obligations. Notwithstanding anything to the contrary contained in this Lease, Tenant shall have no liability in connection with any Hazardous Materials (i) in existence on the Premises, Building or Project prior to the applicable Lease Commencement Date or brought or introduced onto the Premises, Building or Project after the applicable Lease Commencement Date by any party other than Tenant or a Tenant’s Party or (ii) which may migrate into the Premises, Building or Project from outside of the Project through no fault of Tenant or any of Tenant’s Parties (the “Excluded Matters”).

The Premises, the Building and the Project has not been occupied since that date of the Phase I Report. It being acknowledged, that Landlord shall, at its sole cost and expense (without inclusion as an Operating Expense), be responsible for any restoration, remediation or other corrective actions required or occasioned by any Excluded Matters.

Landlord and Tenant therefore agree that Tenant shall not cause or permit (or conduct any activities that would cause) any release of any odors or fumes of any kind from the Premises (except through a ventilation system installed under the Work Letter or otherwise in a manner that is adequate, suitable and appropriate to vent the Premises).

Landlord’s approval of the plans, specifications and working drawings for Tenant’s Alterations shall create no responsibility or liability on the part of Landlord for their completeness, design sufficiency, or compliance with all laws, rules and regulations of governmental agencies or authorities. All work with respect to any Alterations must be

8.3 Landlord’s Property. All Alterations, improvements, fixtures and/or equipment which may be installed or placed in or about the Premises (including, but not limited to, all floor and wall coverings, built-in cabinet work and paneling, sinks and related plumbing fixtures, laboratory benches, exterior venting fume hoods and walk-in freezers and refrigerators, ductwork, conduits, electrical panels and circuits), shall be at the sole cost of Tenant. Upon the expiration or early termination of the Lease Term, at Landlord’s election in its sole discretion, such Alterations, improvements, fixtures and/or equipment, or any of them, shall become the property of Landlord, except that Tenant shall retain ownership and be entitled to remove all fixtures and equipment paid for by Tenant’s own funds provided that Tenant repairs any damage to the Premises caused by such removal. Furthermore, Landlord may, at the time of its approval of any such Alteration requested, require that Tenant remove such Alterations, improvements, fixtures and/or equipment, or any of them, upon the expiration or early termination of the Lease Term, and repair any damage to the Premises and Building caused by such removal. If Tenant fails to complete such removal and/or to repair by the end of the Lease Term, Landlord may do so and may charge the cost thereof to Tenant. Notwithstanding any other provision of this Article 8 to the contrary, in no event shall Tenant remove any improvement from the Premises as to which Landlord contributed payment, including the Tenant Improvements, without Landlord’s prior written consent, which consent Landlord may withhold in its sole and absolute discretion.

8.4 Wi-Fi Network. Without limiting the generality of the foregoing, if Tenant desires to install wireless intranet, Internet and communications network (“Wi-Fi Network”) in the Premises for the use by Tenant and its employees, then the same shall be subject to the provisions of this Section 8.4 (in addition to the other provisions of this Article 8). In the event Tenant installs such Wi-Fi Network, Tenant may, but shall not be obligated to, remove the Wi-Fi Network from the Premises prior to the termination of the Lease. In the event that Tenant leaves the Wi-Fi Network at the expiration or earlier termination of the Lease Term, Tenant shall leave any Wi-Fi Network cabling clearly labeled. Landlord makes no representation that the Wi-Fi Network will be able to receive or transmit communication signals without interference or disturbance. Tenant shall (i) be solely responsible for any damage caused as a result of the Wi-Fi Network, (ii) promptly pay any tax, license or permit fees charged pursuant to any laws or regulations in connection with the installation, maintenance or use of the Wi-Fi Network and comply with all precautions and safeguards recommended by all governmental authorities, (iii) pay for all necessary repairs, replacements to or maintenance of the Wi-Fi Network, and (iv) be responsible for any modifications, additions or repairs to the Building or Project, including without limitation, Building or Project systems or infrastructure, which are required by reason of the installation, operation or removal of Tenant’s Wi-Fi Network.

ARTICLE 9

COVENANT AGAINST LIENS

Tenant has no authority or power to cause or permit any lien or encumbrance of any kind whatsoever, whether created by act of Tenant, operation of law or otherwise, to attach to or be placed upon the Project, Building or Premises, and any and all liens and encumbrances created by Tenant shall attach to Tenant’s interest only. Landlord shall have the right at all times to post and keep posted on the Premises any notice which it deems necessary for protection from such liens. Tenant shall not cause or permit any lien of mechanics or materialmen or others to be placed against the Project, the Building or the Premises with respect to work or services claimed to have been performed for or materials claimed to have been furnished to Tenant (other than that performed by Landlord), and, in case of any such lien attaching or notice of any lien, any Tenant shall take all actions required by Landlord’s title insurance company such that said title insurance company shall remove or “insure over” any such lien or notice of contract with respect to any title insurance policies issued to Landlord or Landlord’s lender(s) with respect to the Project, except in case of a Notice of Contract pursuant to Massachusetts General Laws Chapter 254, Sections 2, 2C, 2D or 4, which Landlord acknowledges contractors have, subject to the terms and conditions of such laws, a right to file, Tenant shall cause a Notice of Substantial Completion to be filed upon completion of the work. If any such action has not been taken by Tenant within fifteen (15) business days after Landlord notified Tenant of the existence of such lien or notice, then Landlord may, at its option, take all action necessary to release and remove such lien, without any duty to investigate the validity thereof, and all sums, costs and expenses, including reasonable attorneys’ fees and costs, incurred by Landlord in connection with such lien shall be deemed Additional Rent under this Lease and shall immediately be due and payable by Tenant; provided, however, Tenant shall have the right, but not the obligation, to contest the validity of any such lien provided that Tenant deposits with Landlord such security as Landlord shall reasonably demand to ensure the payment of the lien claim. In the event that Tenant leases or finances the acquisition of equipment, furnishings or other personal property of a removable nature utilized by Tenant in the operation of Tenant’s business, Tenant warrants that any Uniform Commercial Code financing statement shall, upon its face or by exhibit thereto, indicate that such financing statement is applicable only to removable personal property of Tenant located within the Premises. In no event shall the address of the Premises be furnished on a financing statement without qualifying language as to applicability of the lien only to removable personal property located in within the Premises. Should any holder of a financing statement record or place of record a financing statement that appears to constitute a lien against any interest of

Landlord or against equipment that may be located other than within Premises leased by Tenant, Tenant shall, within fifteen (15) days after filing such financing statement, cause (a) a copy of the Lender security agreement or other documents to which the financing statement pertains to be furnished to Landlord to facilitate Landlord’s ability to demonstrate that the lien of such financing statement is not applicable to Landlord’s interest and (b) Tenant’s lender to amend such financing statement and any other documents of record to clarify that any liens imposed thereby are not applicable to any interest of Landlord in the Premises.

ARTICLE 10

INDEMNIFICATION AND INSURANCE

10.1 Indemnification and Waiver. Tenant hereby assumes all risk of damage to property and injury to persons, in, on, or about the Premises from any cause whatsoever and agrees that Landlord and the Landlord Parties shall not be liable for, and are hereby released from any responsibility for, any damage to property or injury to persons or resulting from the loss of use thereof on account of such damage or injury, which damage or injury is sustained by Tenant or by other persons claiming through Tenant, except to the extent caused by the willful misconduct or negligence of Landlord or any Landlord Party. Tenant shall indemnify, defend, protect, and hold harmless the Landlord Parties from any and all loss, cost, damage, expense and liability (including without limitation court costs and reasonable attorneys’ fees) incurred in connection with or arising from any cause in, on or about the Premises (including, without limitation, Tenant’s installation, placement and removal of Alterations, improvements, fixtures and/or equipment in, on or about the Premises), and any acts, omissions or negligence of Tenant or of any person claiming by, through or under Tenant, or of the contractors, agents, servants, employees, licensees or invitees of

Tenant; provided, however, that the terms of the foregoing indemnity shall not apply to (i) the negligence or willful misconduct of Landlord or any Landlord Party, and (ii) Tenant’s indemnity obligations shall not extend to loss of business, loss of profits or other consequential damages which may be suffered by Landlord. The provisions of this Section 10.1 shall survive the expiration or sooner termination of this Lease with respect to events occurring during the Term. Notwithstanding anything in this Lease to the contrary but subject to Landlord’s indemnity obligations in Section 10.7 below, Landlord shall not be liable to Tenant for, and Tenant assumes all risk of, damage to personal property or scientific research resulting from such damage, including loss of records kept by Tenant within the Premises and damage or losses caused by fire, electrical malfunction, gas explosion or water damage of any type (including broken water lines, malfunctioning fire sprinkler systems, malfunctioning lab systems including any malfunction of the central plant systems, roof leaks or stoppages of lines). Tenant further waives any claim for injury to Tenant’s business or loss of income relating to any such damage or destruction of personal property as described above.

10.2 Tenant’s Compliance with Landlord’s Fire and Casualty Insurance. Tenant shall, at Tenant’s expense, comply as to the Premises with all commercially reasonable insurance company requirements pertaining to the use of the Premises. If Tenant’s conduct or use of the Premises causes any increase in the premium for such insurance policies, then Tenant shall reimburse Landlord for any such increase. Tenant, at Tenant’s expense, shall comply with all applicable rules, orders, regulations or requirements of the American Insurance Association (formerly the National Board of Fire Underwriters) and with any similar body.

10.3 Tenant’s Insurance. Tenant shall maintain the following coverages in the following amounts:

10.3.1 Commercial General Liability Insurance covering the insured against claims of bodily injury, personal injury and property damage arising out of Tenant’s operations, assumed liabilities or use of the Premises, including a Broad Form Commercial General Liability endorsement covering the insuring provisions of this Lease and the performance by Tenant of the indemnity agreements set forth in Section 10.1 above, (and liquor liability coverage if alcoholic beverages are served on the Premises) for limits of liability not less than:


Bodily Injury and	$	10,000,000 each occurrence
Property Damage Liability	$	10,000,000 annual aggregate
Personal Injury Liability	$	10,000,000 each occurrence
	$	10,000,000 annual aggregate

10.3.2 Physical Damage Insurance covering (i) all furniture, trade fixtures, equipment, merchandise and all other items of Tenant’s property on the Premises installed by, for, or at the expense of Tenant, (ii) the Tenant Improvements, including any Tenant Improvements which Landlord permits to be installed above the ceiling of the Premises or below the floor of the Premises, and (iii) all other improvements, alterations and additions to the Premises, including any improvements, alterations or additions installed at Tenant’s request above the ceiling of the Premises or below the floor of the Premises (provided, however, Landlord will be responsible, at its cost and expense, for carrying builder’s risk insurance for the work under the Tenant Work Letter). Such insurance shall be written on a “physical loss or damage” basis under a “special form” policy, for the full replacement cost value new without deduction for depreciation of the covered items and in amounts that meet any co-insurance clauses of the policies of insurance and shall include a vandalism and malicious mischief endorsement and sprinkler leakage coverage.

10.3.3 Workers’ compensation insurance as required by law.

10.3.4 Loss-of-income, business interruption and extra-expense insurance in such amounts as will reimburse Tenant for direct and indirect loss of earnings attributable to all perils commonly insured against by prudent tenants or attributable to prevention of loss of access to the Premises or to the Building as a result of such perils.

ActiveUS 186012966v.2

10.3.5 Tenant shall carry commercial automobile liability insurance having a combined single limit of not less than Two Million Dollars ($2,000,000.00) per occurrence and insuring Tenant against liability for claims arising out of ownership, maintenance or use of any owned, hired or non-owned automobiles.

10.3.6 Environmental Liability insurance (in form and substance satisfactory to Landlord) with limits of coverage not less than Five Million Dollars ($5,000,000.00) combined per occurrence and in the aggregate insuring against any and all liability for which Tenant is responsible for under the express terms of this Lease with respect to the Premises and all areas appurtenant thereto arising out of any death or injury to any person, damage or destruction of any property, other loss, cost or expense resulting from any release, spill, leak or other contamination of the Premises, or any other property surrounding the Premises attributable to the presence of Hazardous Materials. If, at any time it reasonably appears to Landlord that Tenant is not maintaining sufficient insurance or other means of financial capacity to enable Tenant to fulfill its obligations to Landlord hereunder, whether or not then accrued, liquidated, conditional or contingent, Tenant shall procure and thereafter maintain in full force and effect such insurance or other form of financial assurance, in form and substance reasonably acceptable to Landlord and from companies having a rating of not less than A–/VII in Best’s Insurance Guide, as Landlord may from time to time reasonably request. Without limiting the generality of the foregoing, all such environmental liability insurance shall specifically insure the performance by Tenant of the indemnity provisions set forth in this Lease.

10.3.7 Form of Policies. The minimum limits of policies of insurance required of Tenant under this Lease shall in no event limit the liability of Tenant under this Lease. Such insurance shall: (i) name Landlord, and any other party it so specifies in writing to Tenant, as an additional insured with respect to the commercial general liability insurance; (ii) specifically cover the liability assumed by Tenant under this Lease, including, but not limited to, Tenant’s obligations under Section 10.1 above; (iii) be issued by an insurance company having a rating of not less than A–/VII in Best’s Insurance Guide or which is otherwise acceptable to Landlord and authorized to do business in the state in which the Project is located; (iv) be primary insurance as to all claims thereunder and provide that any insurance carried by Landlord is excess and is non-contributing with any insurance requirement of Tenant; (v) provide that said insurance shall not be canceled or coverage changed unless thirty (30) days’ prior written notice shall have been given to Landlord and any mortgagee or ground or underlying lessor of Landlord (provided Tenant will not be in default if the insurance company refuses to provide such assurance); (vi) contain a cross-liability endorsement or severability of interest clause acceptable to Landlord; and (vii) with respect to the insurance required in Sections 10.3.1, 10.3.2 and 10.3.4 above, have deductible amounts not exceeding One Hundred Thousand Dollars ($100,000.00). Tenant shall deliver certificates thereof to Landlord on or before the Lease Commencement Date and at least thirty (30) days before the expiration dates thereof. If Tenant shall fail to procure such insurance, or to deliver such certificates and endorsements, within such time periods, Landlord may, at its option, in addition to all of its other rights and remedies under this Lease, and without regard to any notice and cure periods set forth in Section 19.1, procure such policies for the account of Tenant, and the cost thereof shall be paid to Landlord as Additional Rent within thirty (30) days after delivery of bills therefor.

10.4 Waiver of Subrogation. Landlord and Tenant each hereby waive all rights of recovery against the other on account of loss and damage occasioned to the property of such waiving party to the extent that the waiving party is entitled to proceeds for such loss and damage (or would be entitled, if the policy was obtained and complied with) under any property insurance policies and workers’ compensation insurance policies carried or otherwise required to be carried by this Lease; provided, however, that the foregoing waiver shall not apply to the extent of Tenant’s or Landlord’s obligation to pay deductibles under any such policies and this Lease. By this waiver it is the intent of the parties that neither Landlord nor Tenant shall be liable to any insurance company (by way of subrogation or otherwise) insuring the other party for any loss or damage insured against under any property insurance policies, even though such loss or damage might be occasioned by the negligence of such party, its agents, employees, contractors or invitees. The foregoing waiver by Tenant shall also inure to the benefit of Landlord’s management agent for the Building.

10.5 Additional Insurance Obligations. Tenant shall carry and maintain during the entire Lease Term, at Tenant’s sole cost and expense, amounts of the insurance required to be carried by Tenant pursuant to this Article 10, and such other reasonable types of insurance coverage and in such reasonable amounts covering the Premises and Tenant’s operations therein, as may be reasonably requested by Landlord, consistent with industry standards.

ActiveUS 186012966v.2

10.6 Landlord’s Insurance. During the Lease Term, Landlord, as part of Operating Expenses, shall maintain property insurance covering the Project (excluding the property which Tenant is obligated to insure pursuant to the terms hereof) in the amount of the full replacement cost thereof. Such policy shall provide protection against “all risk of physical loss”. Such insurance shall be in such amounts and with such deductibles as Landlord reasonably deems appropriate but consistent with the insurance generally maintained by other institutional owners of comparable buildings in the Market Area (as defined in Rider 1 attached hereto). Landlord shall further procure and maintain commercial general liability insurance with a single loss limit of not less than $2,000,000 for bodily injury and property damage with respect to the Project. Landlord may, but shall not be obligated to, obtain and carry any other form or forms of insurance as Landlord or Landlord’s mortgagees or deed of trust beneficiaries may reasonably determine prudent; provided that the same is consistent with the insurance generally maintained by institutional owners of comparable buildings in the Market Area. Notwithstanding any contribution by Tenant to the cost of insurance as provided in this Lease, Tenant acknowledges that it has no right to receive any proceeds from any insurance policies maintained by Landlord (other than Landlord’s commercial general liability insurance with respect to claims pursuant to which Tenant is entitled to such insurance proceeds) and will not be named as an additional insured thereunder.

10.7 Landlord Indemnification. Landlord shall indemnify, defend, protect, and hold harmless Tenant and the Tenant’s Parties from and against any and all loss, cost, damage, expense and liability (including without limitation court costs and reasonable attorneys’ fees) incurred in connection with or arising from (1) the negligence or misconduct of Landlord or the Landlord Parties in, on or about the Project, (2) any breach of any representation or warranty contained herein, (3) the use, generation, storage, treatment, or the disposal or other release of any Hazardous Materials by Landlord or any Landlord Party or otherwise relating to the Excluded Matters, or (4) any violation by Landlord of any law applicable to the Project; provided, however, that (i) the terms of the foregoing indemnity shall not apply to the negligence or willful misconduct of Tenant or the Tenant’s Parties and (ii) Landlord’s indemnity obligations shall not extend to loss of business, loss of profits or other consequential damages which may be suffered by Tenant. The provisions of this Section 10.7 shall survive the expiration or sooner termination of this Lease.

ARTICLE 11

DAMAGE AND DESTRUCTION

11.1 Repair of Damage to Premises by Landlord. Tenant shall promptly notify Landlord of any damage to the Premises resulting from fire or any other casualty. Landlord shall notify Tenant within sixty (60) days after its discovery of any damage to the Building or any areas of the Project as to the amount of time Landlord reasonably estimates it will take to restore the Project or portion thereof, as applicable (the “Restoration Period”). If the Building or any areas of the Project shall be damaged by fire or other casualty, Landlord shall promptly and diligently, subject to reasonable delays for insurance adjustment or other matters beyond Landlord’s reasonable control, and subject to all other terms of this Article 11, restore the Project and the base, shell, and core of the Premises. Such restoration shall be to substantially the same condition prior to the casualty, except for modifications required by zoning and building codes and other laws or by the holder of a mortgage on the Project and/or the Building. Upon the occurrence of any damage to the Premises, Tenant shall assign to Landlord (or to any party designated by Landlord) all insurance proceeds payable to Tenant under Tenant’s insurance required under Section 10.3 of this Lease (to the extent the same is for items Landlord is required to repair), and Landlord shall repair any damage to the tenant improvements and alterations installed in the Premises and shall return such tenant improvements and alterations to their original condition prior to such damage; provided that if the costs of such repair of such tenant improvements and Alterations by Landlord exceeds the amount of insurance proceeds received by Landlord therefor from Tenant’s insurance carrier, as assigned by Tenant, the excess costs of such repairs shall be paid by Tenant to Landlord prior to Landlord’s repair of the damage (or, at Tenant’s election, the repair shall be reduced so as not to exceed the proceeds). In connection with such repairs and replacements of any such tenant improvements and Alterations, Tenant shall, prior to Landlord’s commencement of such improvement work, submit to Landlord, for Landlord’s review and approval, all plans, specifications and working drawings relating thereto, and Landlord shall select the contractors to perform such improvement work. Landlord shall not be liable for any inconvenience or annoyance to Tenant or its visitors, or injury to Tenant’s business resulting in any way from such

damage or the repair thereof; provided however, that if such fire or other casualty shall have damaged the Premises or Tenant’s access to the Premises (or the restoration activities interfere therewith), and if such damage is not the result of the negligence or willful misconduct of Tenant or Tenant’s employees, contractors, licensees, or invitees, Landlord shall allow Tenant a proportionate abatement of Base Rent and Tenant’s Share of Operating Expenses, Tax Expenses and Utilities Costs during the time and to the extent the Premises are unfit for occupancy for the purposes permitted under this Lease, and not occupied by Tenant as a result thereof.

11.2 Landlord’s Option to Repair. Notwithstanding Section 11.1 above to the contrary, Landlord may elect not to rebuild and/or restore the Premises, the Building and/or any other portion of the Project and instead terminate this Lease by notifying Tenant in writing of such termination within sixty (60) days after the date Landlord becomes aware of such damage, such notice to include a termination date giving Tenant ninety (90) days to vacate the Premises, but Landlord may so elect only if the Building shall be damaged by fire or other casualty or cause, whether or not the Premises are affected, and one or more of the following conditions is present: (i) repairs cannot reasonably be substantially completed within two hundred seventy (270) days after the date of such damage (when such repairs are made without the payment of overtime or other premiums) (the “Maximum Restoration Period”); (ii) the holder of any mortgage on the Project and/or the Building or ground or underlying lessor with respect to the Project and/or the Building shall require that the insurance proceeds or any portion thereof be used to retire the mortgage debt, or shall terminate the ground or underlying lease, as the case may be; or (iii) the damage is not fully covered, except for deductible amounts, by Landlord’s insurance policies. In addition, if the Premises or the Building is destroyed or damaged to any substantial extent during the last year of the Lease Term, then notwithstanding anything contained in this Article 11, Landlord or Tenant shall have the option to terminate this Lease by giving written notice to the other of the exercise of such option within thirty (30) days after such damage, in which event this Lease shall cease and terminate as of the date of such notice. In the event Landlord’s estimate notice indicates that the Restoration Period for damage or destruction to the Building or portion of the Property is expected to exceed the Maximum Restoration Period, then Tenant shall have the right to terminate this Lease by written notice to Landlord within thirty (30) days following the date Tenant receives Landlord’s restoration estimate notice. If the repair or restoration of the Premises and Project is not substantially complete at the end of the Maximum Restoration Period, then Tenant may elect to terminate the Lease by at least thirty (30) days prior written notice to Landlord given within thirty (30) days following expiration of the Maximum Restoration Period; provided that such termination notice shall be null and void if Landlord substantially completes the restoration within such thirty (30) day period. Upon any such termination of this Lease pursuant to this Section 11.2, Tenant shall pay the Base Rent and Additional Rent, properly apportioned (based on the time and to the extent the Premises are unfit for occupancy for the purposes permitted under this Lease, and not occupied by Tenant as a result thereof) up to such date of termination, and both parties hereto shall thereafter be discharged of all further obligations under this Lease, except for those obligations which expressly survive the expiration or earlier termination of the Lease Term. In the event of any termination of this Lease as a result of a casualty, Tenant shall be entitled to all insurance proceeds relating to Alterations or improvements to the extent paid by Tenant.

11.3 Waiver of Statutory Provisions. The provisions of this Lease, including this Article 11, constitute an express agreement between Landlord and Tenant with respect to any and all damage to, or destruction of, all or any part of the Premises, the Building or any other portion of the Project, and any statute or regulation of the state in which the Project is located, with respect to any rights or obligations concerning damage or destruction in the absence of an express agreement between the parties, and any other statute or regulation, now or hereafter in effect, shall have no application to this Lease or any damage or destruction to all or any part of the Premises, the Building or any other portion of the Project.

ARTICLE 12

CONDEMNATION

12.1 Permanent Taking. If the whole or any material part of the Premises, Building or Project shall be taken by power of eminent domain or condemned by any competent authority for any public or quasi-public use or purpose, and the taking would either prevent or materially interfere with Tenant’s use of, or access to, the Premises (as determined by Tenant, in Tenant’s reasonable judgment), then upon written notice by Landlord or Tenant this

908728.01/SD

374622.00146/4-30-21/MLT/bp

ActiveUS 186012966v.2

Lease shall terminate and all rent shall be apportioned as of said date. In the event a taking affects Tenant’s reasonable access to the Premises, more than 10% of the Premises (whether or not it interferes with Tenant’s use of the Premises), or otherwise renders the Premises unsuitable for Tenant’s business in the good faith of Tenant, then Tenant may terminate this Lease upon written notice to Landlord, in which case this Lease shall terminate and the all rent shall be apportioned as of such date. Landlord shall be entitled to receive the entire award or payment in connection therewith, except that Tenant shall have the right to file any separate claim available to Tenant for any taking of Tenant’s personal property and fixtures belonging to Tenant and removable by Tenant upon expiration of the Lease Term pursuant to the terms of this Lease, and for moving expenses, so long as such claim does not diminish the award available to Landlord, or its ground lessor or mortgagee with respect to the Project, and such claim is payable separately to Tenant. All Rent shall be apportioned as of the date of such termination, or the date of such taking, whichever shall first occur. If any part of the Project shall be taken, and this Lease shall not be so terminated, then Landlord shall promptly restore the Premises and the Project as nearly as is commercially reasonable under the circumstance to their condition prior to such partial taking and the rentable square footage of the Building, the rentable square footage of the Premises, Base Rent and Tenant’s Share of Operating Expenses, Tax Expenses and Utilities Costs shall be proportionately abated (and also taking into account loss of parking).

12.2 Temporary Taking. Notwithstanding anything to the contrary contained in this Article 12, in the event of a temporary taking of all or any portion of the Premises for a period of one hundred and eighty (180) days or less, then this Lease shall not terminate but the Base Rent and Tenant’s Share of Operating Expenses, Tax Expenses and Utilities Costs shall be abated for the period of such taking in proportion to the ratio that the amount of rentable square feet of the Premises taken bears to the total rentable square feet of the Premises. Landlord shall be entitled to receive the entire award made in connection with any such temporary taking.

ARTICLE 13

COVENANT OF QUIET ENJOYMENT

Landlord covenants that Tenant, on paying the Rent, charges for services and other payments herein reserved and on keeping, observing and performing all the other terms, covenants, conditions, and agreements herein contained on the part of Tenant to be kept, observed and performed, shall, during the Lease Term, peaceably and quietly have, hold and enjoy the Premises subject to the terms, covenants, conditions, and agreements hereof without interference by any persons. The foregoing covenant is in lieu of any other covenant express or implied.

ARTICLE 14

ASSIGNMENT AND SUBLETTING

14.1 Transfers. Tenant shall not, without the prior written consent of Landlord, assign, mortgage, pledge, hypothecate, encumber, or permit any lien to attach to, or otherwise transfer, this Lease or any interest hereunder, permit any assignment or other such foregoing transfer of this Lease or any interest hereunder by operation of law, sublet the Premises or any part thereof, or permit the use of the Premises by any persons other than Tenant and its employees (all of the foregoing are hereinafter sometimes referred to collectively as “Transfers” and any person to whom any Transfer is made or sought to be made is hereinafter sometimes referred to as a “Transferee”). If Tenant shall desire Landlord’s consent to any Transfer, Tenant shall notify Landlord in writing, which notice (the “Transfer Notice”) shall include (i) the proposed effective date of the Transfer, which shall not be less than fifteen (15) days nor more than one hundred eighty (180) days after the date of delivery of the Transfer Notice, (ii) a description of the portion of the Premises to be transferred (the “Subject Space”), (iii) all of the terms of the proposed Transfer, the name and address of the proposed Transferee, and a copy of the proposed sublease or assignment document, (iv) current financial statements of the proposed Transferee certified by an officer, partner or owner thereof (subject to Landlord executing a reasonable confidentiality agreement), (v) a list of Hazardous Materials, certified by the proposed Transferee to be true and correct, that the proposed Transferee intends to use or store in the Subject Space, and (vi) such other information as Landlord may reasonably require. Any Transfer made without Landlord’s prior written consent shall, at Landlord’s option, be null, void and of no effect, and shall, at Landlord’s option, constitute a default by Tenant under this Lease. Whether or not Landlord shall grant consent,

within thirty (30) days after written request by Landlord, Tenant shall pay to Landlord Two Thousand Five Hundred Dollars ($2,500.00) to reimburse Landlord for its review, processing, and legal fees incurred by Landlord in connection with Tenant’s proposed Transfer.

14.2 Landlord’s Consent. Landlord shall not unreasonably withhold, condition or delay its consent to any proposed Transfer on the terms specified in the Transfer Notice and shall grant or deny its consent within fifteen (15) days following request therefor. In no event shall Landlord be deemed to be unreasonable for declining to consent to a Transfer to a transferee jeopardizing directly or indirectly the status of Landlord or any of Landlord’s affiliates as a Real Estate Investment Trust under the Internal Revenue Code of 1986 (as the same may be amended from time to time, the “Revenue Code”). Notwithstanding anything contained in this Lease to the contrary, (x) no Transfer shall be consummated on any basis such that the rental or other amounts to be paid by the occupant, assignee, manager or other transferee thereunder would be based, in whole or in part, on the income or profits derived by the business activities of such occupant, assignee, manager or other transferee; (y) Landlord may withhold its consent to a Transfer with any person in which Landlord owns an interest, directly or indirectly (by applying constructive ownership rules set forth in Section 856(d)(5) of the Revenue Code); and (z) Tenant shall not consummate a Transfer with any person or in any manner that would cause any portion of the

amounts received by Landlord pursuant to this Lease or any sublease, license or other arrangement for the right to use, occupy or possess any portion of the Premises to fail to qualify as “rents from real property” within the meaning of Section 856(d) of the Revenue Code, or any similar or successor provision thereto. The parties hereby agree that it shall be reasonable under this Lease and under any applicable law for Landlord to withhold consent to any proposed Transfer where one or more of the following apply, without limitation as to other reasonable grounds for withholding consent:

14.2.1 The Transferee is of a character or reputation or engaged in a business which is not consistent with the quality of the Building or Project;

14.2.2 The Transferee intends to use the Subject Space for purposes which are not permitted under this Lease;

14.2.3 The Transferee is either a governmental agency or instrumentality thereof;

14.2.4 The Transferee is not a party of reasonable financial worth and/or financial stability in light of the responsibilities involved under the Lease on the date consent is requested; or

14.2.5 Either the proposed Transferee, or any person or entity which directly or indirectly, controls, is controlled by, or is under common control with, the proposed Transferee, (i) is negotiating with Landlord to lease space in the Project at such time, or (ii) has negotiated with Landlord during the three (3)-month period immediately preceding the Transfer Notice for space in the Project.

If Landlord consents to any Transfer pursuant to the terms of this Section 14.2 (and does not exercise any recapture rights Landlord may have under Section 14.4 below), Tenant may within six (6) months after Landlord’s consent, enter into such Transfer of the Premises or portion thereof, upon substantially the same terms and conditions as are set forth in the Transfer Notice furnished by Tenant to Landlord pursuant to Section 14.1 above, provided that if there are any material changes in the terms and conditions from those specified in the Transfer Notice (i) such that Landlord would initially have been entitled to refuse its consent to such Transfer under this Section 14.2, or (ii) which would cause the proposed Transfer to be materially more favorable to the Transferee than the terms set forth in Tenant’s original Transfer Notice, Tenant shall again submit the Transfer to Landlord for its approval and other action under this Article 14 (including Landlord’s right of recapture, if any, under Section 14.4 of this Lease).

14.3 Transfer Premium.

excess of the Rent and Additional Rent payable by Tenant under this Lease on a per rentable square foot basis if less than all of the Premises is transferred, after deducting all reasonable expenses incurred by Tenant, including, without limitation, (i) any reasonable changes, alterations and improvements to the Premises in

connection with the Transfer (but only to the extent approved by Landlord), (ii) any reasonable legal costs, advertising costs, or brokerage commissions in connection with the Transfer (collectively, the “Subleasing Costs”). Transfer Premium shall also include, but not be limited to, key money and bonus money paid by Transferee to Tenant for the Transfer of the Lease, and any payment in excess of fair market value for services rendered by Tenant to Transferee or for assets, fixtures, inventory, equipment, or furniture transferred by Tenant to Transferee in connection with such Transfer. Notwithstanding the foregoing and for the avoidance of doubt, there shall be no Transfer Premium in connection with any of the transactions contemplated in Section 14.7.

14.4 Landlord’s Option as to Subject Space. Notwithstanding anything to the contrary contained in this Article 14, Landlord shall have the option, by giving written notice to Tenant within ten (10) days after receipt of any Transfer Notice for an assignment or a sublease of the entire Premises, to recapture the Subject Space; provided that with respect to subleases, the foregoing recapture right shall only apply to a proposed subleases with a term for the balance of the then-remaining Lease Term. If Landlord exercises such right of recapture, then Tenant may within ten (10) business days after receipt of Landlord elect to withdraw its Transfer Notice, and in such event the Lease shall continue in full force and effect. If Tenant does not timely elect to withdraw its request, the recapture notice shall terminate this Lease with respect to the Subject Space as of the date stated in the Transfer Notice as the effective date of the proposed Transfer until the last day of the term of the Transfer as set forth in the Transfer Notice. If Landlord declines, or fails to elect in a timely manner to recapture the Subject Space under this Section 14.4, then, provided Landlord has consented to the proposed Transfer, Tenant shall be entitled to proceed to transfer the Subject Space to the proposed Transferee, subject to provisions of the last paragraph of Section 14.2 above. Notwithstanding the foregoing and for the avoidance of doubt, Landlord shall have no right to recapture in connection with any of the transactions completed in Section 14.7.

14.5 Effect of Transfer. If Landlord consents to a Transfer: (i) the terms and conditions of this Lease shall in no way be deemed to have been waived or modified; (ii) such consent shall not be deemed consent to any further Transfer by either Tenant or a Transferee; (iii) Tenant shall deliver to Landlord, promptly after execution, an original executed copy of the sublease or assignment document; and (iv) no Transfer relating to this Lease or agreement entered into with respect thereto, whether with or without Landlord’s consent, shall relieve Tenant or any guarantor of the Lease from liability under this Lease. Subject to executing Tenant’s standard confidentiality agreement, Landlord or its authorized representatives shall have the right at all reasonable times to audit the books, records and papers of Tenant relating to any Transfer Premium, and shall have the right to make copies thereof. If the Transfer Premium respecting any Transfer shall be found understated, Tenant shall, within thirty (30) days after demand, pay the deficiency and Landlord’s costs of such audit.

14.7.3 Any such Affiliate has, following the effective date of any such assignment, sublease, financing or public offering, a tangible net worth, in the aggregate, computed in accordance with generally accepted accounting principles, which is equal to or greater than Tenant as of the date prior to the Transfer;

14.7.4 In the case of an assignment or sublease, any such Affiliate shall assume, in a written document delivered to Landlord upon or prior to the effective date of such assignment or sublease (unless precluded by non-disclosure obligations, in which case Tenant shall provide to Landlord as soon as possible thereafter), all the obligations of Tenant under this Lease, and any such Affiliate sublessee shall acknowledge, in a written document delivered to Landlord upon or prior to the effective date of such sublease, that its rights are subordinate to this Lease and that it agrees not to violate any provision of this Lease; and

ARTICLE 15

SURRENDER; OWNERSHIP AND REMOVAL OF PERSONAL PROPERTY

15.1 Surrender of Premises. No act or thing done by Landlord or any agent or employee of Landlord during the Lease Term shall be deemed to constitute an acceptance by Landlord of a surrender of the Premises unless such intent is specifically acknowledged in a writing signed by Landlord. The delivery of keys to the Premises to Landlord or any agent or employee of Landlord shall not constitute a surrender of the Premises or effect a termination of this Lease, whether or not the keys are thereafter retained by Landlord, and notwithstanding such delivery Tenant shall be entitled to the return of such keys at any reasonable time upon request until this Lease shall have been properly terminated. The voluntary or other surrender of this Lease by Tenant, whether accepted by Landlord or not, or a mutual termination hereof, shall not work a merger, and at the option of Landlord shall operate as an assignment to Landlord of all subleases or subtenancies affecting the Premises.

15.2 Removal of Tenant Property by Tenant. Upon the expiration of the Lease Term, or upon any earlier termination of this Lease, Tenant shall, subject to the provisions of this Article 15, quit and surrender possession of the Premises to Landlord in good order and condition, reasonable wear and tear, casualty loss and condemnation, damage by Landlord or any Landlord Party, and repairs which are specifically made the responsibility of Landlord hereunder excepted. Tenant’s restoration obligations may also include satisfying Landlord’s commercially reasonable procedures regarding the cleaning of any lab systems and sealing any connection points of any such lab systems to the Premises, all at Tenant’s sole cost and expense; provided that Landlord has provided the requirement for such procedures at least one hundred twenty (120) days prior to Tenant’s surrender of the Premises. Prior to Tenant’s surrender of possession of any part of the Premises, Tenant shall provide Landlord with (a) a facility decommissioning and Hazardous Materials closure plan for the Premises (“Exit Survey”) prepared by an independent third party reasonably acceptable to Landlord, and (b) written evidence of all appropriate governmental releases obtained by Tenant in accordance with applicable laws, including laws pertaining to the surrender of the Premises. In addition, Tenant agrees to remain responsible after the surrender of the Premises for the remediation of any recognized environmental conditions set forth in the Exit Survey to the extent such recognized environmental conditions were caused by Tenant or the Tenant’s Parties and compliance with any recommendations set forth in the Exit Survey to the extent relating to recognized environmental conditions caused by Tenant or the Tenant’s Parties.

Tenant shall, upon the expiration or earlier termination of this Lease, furnish to Landlord evidence that Tenant has closed all governmental permits and licenses, if any, issued in connection with Tenant’s or Tenant’s Parties’ activities at the Premises. Upon such expiration or termination of this Lease, Tenant may, but shall not be obligated to, remove or cause to be removed from the Premises all telephone, data, and other cabling and wiring (including any cabling and wiring associated with the Wi-Fi Network, if any) installed or caused to be installed by Tenant (including any cabling and wiring, installed above the ceiling of the Premises or below the floor of the Premises), and Tenant shall label the same if not removed. Tenant shall remove all debris and rubbish, and such items of furniture, equipment, free-standing cabinet work, and other articles of personal property owned by Tenant or installed or placed by Tenant at its expense in the Premises, and such similar articles of any other persons claiming under Tenant, and Tenant shall repair at its own expense all damage to the Premises and Building resulting from such removal. Tenant’s obligations under this Section 15.2 shall survive the expiration or earlier termination of this Lease.

ARTICLE 16

HOLDING OVER

If Tenant holds over after the expiration of the Lease Term hereof, with or without the express or implied consent of Landlord, such tenancy shall be at sufferance, and shall not constitute a renewal hereof or an extension for any further term, and in such case Base Rent shall be payable at a monthly rate (prorated on a daily basis) equal to one hundred fifty percent (150%) of the Base Rent applicable during the last rental period of the Lease Term under this Lease. Such tenancy at sufferance shall be subject to every other term, covenant and agreement contained herein. Landlord hereby expressly reserves the right to require Tenant to surrender possession of the Premises to Landlord as provided in this Lease upon the expiration or other termination of this Lease. The provisions of this Article 16 shall not be deemed to limit or constitute a waiver of any other rights or remedies of Landlord provided herein or at law. If Tenant fails to surrender the Premises upon the termination or expiration of this Lease, in addition to any other liabilities to Landlord accruing therefrom, Tenant shall, to the extent permitted by applicable law, protect, defend, indemnify and hold Landlord harmless from all loss, costs (including reasonable attorneys’ fees) and liability resulting from such failure, including, without limiting the generality of the foregoing, commencing on the date that is sixty (60) days following such holdover, any claims made by any succeeding tenant founded upon such failure to surrender and any lost profits to Landlord resulting therefrom.

ARTICLE 17

ESTOPPEL CERTIFICATES

Within ten (10) business days following a request in writing by Landlord, Tenant shall execute and deliver to Landlord an estoppel certificate, which, as submitted by Landlord, shall be in a commercially customary form as may be reasonably required by any existing or prospective mortgagee or purchaser of the Project (or any portion thereof), indicating therein any exceptions thereto that may exist at that time, and shall also contain any other information reasonably requested by Landlord or Landlord’s mortgagee or Landlord’s prospective mortgagees. Failure of Tenant to timely execute and deliver or dispute such estoppel certificate shall constitute an acceptance of the Premises and an acknowledgment by Tenant that statements included in the estoppel certificate are true and correct, without exception. Failure by Tenant to so deliver such estoppel certificate shall be a material default of the provisions of this Lease. Within ten (10) business days following a request in writing by Tenant, Landlord shall execute and deliver to Tenant an estoppel certificate, which, as submitted by Tenant, shall be in the form as may be reasonably required by any prospective lender, investor, assignee, or subtenant, indicating therein any exceptions thereto that may exist at that time, and shall also contain any other information reasonably requested by Tenant or Tenant’s prospective lenders, investors, assignees, or subtenants. Any such statement may be relied upon by any prospective lender, investor, assignee or subtenant. Upon request from time to time (but no more often than once per calendar year unless required in connection with a recapitalization, financing or refinancing, or sale of the Project), Tenant agrees to provide to Landlord, within fifteen (15) business days after Landlord’s delivery of written request therefor, current financial statements for Tenant, dated no earlier than one (1) year prior to such written request, certified as materially accurate by Tenant or, if available, audited financial statements prepared by an independent

ARTICLE 18

SUBORDINATION

This Lease is subject and subordinate to all present and future ground leases of the Project and to the lien of any mortgages or trust deeds, now or hereafter in force against the Project, if any, and to all renewals, extensions, modifications, consolidations and replacements thereof, and to all advances made or hereafter to be made upon the security of such mortgages or trust deeds, unless the holders of such mortgages or trust deeds, or the lessors under such ground lease, require in writing that this Lease be superior thereto; provided, however, in all cases, so long as there is no default under this Lease (beyond any applicable notice and cure periods), Tenant’s right to possession of the Premises in accordance with the terms of this Lease shall not be disturbed by any such ground lessor or holder of a mortgage/deed of trust and their successors (including purchases at a foreclosure) and Tenant’s right under this Lease shall be recognized by such ground lessor or holder and their successors (including purchasers at a foreclosure). Tenant covenants and agrees in the event any proceedings are brought for the foreclosure of any such mortgage, or if any ground lease is terminated, to attorn, without any deductions or set-offs whatsoever, to the purchaser upon any such foreclosure sale, or to the lessor of such ground lease, as the case may be, if so requested to do so by such purchaser or lessor, and to recognize such purchaser or lessor as the lessor under this Lease. Tenant shall, within fifteen (15) business days of request by Landlord, execute such further commercially reasonable instruments or assurances as Landlord may reasonably deem necessary to evidence or confirm the subordination or superiority of this Lease to any such mortgages, trust deeds, or ground leases, provided that any such instruments contain commercially reasonable non-disturbance provisions assuring Tenant’s quiet enjoyment of the Premises in accordance with the terms of this Lease and that Tenant’s rights under this Lease shall be recognized by such ground lessor or holder and their successors (including purchasers at a foreclosure). Tenant waives the provisions of any current or future statute, rule or law which may give or purport to give Tenant any right or election to terminate or otherwise adversely affect this Lease and the obligations of the Tenant hereunder in the event of any foreclosure proceeding or sale. As of the date of this Lease, Landlord represents and warrants to Tenant that there is no existing mortgage, trust deeds, or ground lease encumbering the Project (or any portion thereof) other than SBNP SIA Mortgage III LLC. Within ten (10) business days after the full execution of this Lease, Landlord shall obtain and deliver to Tenant a fully executed non-disturbance agreement from the holder of any pre-existing mortgage encumbering the Project (or any portion thereof) in the form attached hereto as Exhibit E. If during the Lease Term, there is a future mortgage, trust deed, or ground lease encumbering all or any portion of the Project, Landlord agrees, as a condition to subordination of this Lease to such mortgage, trust, deed or ground lease, to cause the holder of such mortgage or

trust deed, or ground lessor of such ground lease to enter into a commercially reasonable form of subordination, non-disturbance and attornment agreement with Tenant with respect to this Lease, the form of which shall be a commercially reasonable form provided by the mortgagee, trust, deed holder or ground lessor (provided the same recognizes Tenant’s rights under this Lease), incorporating such commercially reasonable modifications requested by Tenant.

(provided that Landlord shall have no obligation to give notices more than one (1) time in any 12 month period for regularly scheduled payments);

19.1.2 Any failure by Tenant to observe or perform any other provision, covenant or condition of this Lease to be observed or performed by Tenant (other than the payment of Rent or Additional Rent) where such failure continues for thirty (30) days after written notice thereof from Landlord to Tenant; provided however that if the nature of such default is such that the same cannot reasonably be cured within a thirty (30)-day period, Tenant shall not be deemed to be in default if it diligently commences such cure within such period and thereafter diligently proceeds to rectify and cure said default as soon as possible;

19.1.3 Intentionally omitted;

19.2 Landlord’s Remedies Upon Default. Upon the occurrence of any such default by Tenant, Landlord shall have, in addition to any other remedies available to Landlord at law or in equity, the option to pursue any one or more of the following remedies, each and all of which shall be cumulative and nonexclusive, without any notice or demand whatsoever.

19.2.1 Upon the happening and during the continuance of any one or more of the aforementioned defaults beyond the applicable notice and cure periods (notwithstanding any license of a former breach of covenant or waiver of the benefit hereof or consent in a former instance), Landlord or Landlord’s agents or servants may, without limitation of any other rights and remedies Landlord may have, at law or in equity, as a result of any default of Tenant under this Lease, give to Tenant a notice terminating this Lease on a date specified in such notice of termination (which shall be not less than ten (10) days after the date of the giving such notice of termination), and this Lease and the Term, as well as any and all of the right, title and interest of the Tenant hereunder, shall wholly cease and expire on the date set forth in such notice of termination (Tenant hereby waiving any rights of redemption) in the same manner and with the same force and effect as if such date were the date originally specified herein for the Lease Expiration Date, and Tenant shall then quit and surrender the Premises to Landlord. Upon a termination of this Lease, Landlord or Landlord’s agents or servants may, by any suitable action or proceeding at law, immediately or at any time thereafter re-enter the Premises and remove therefrom Tenant, its agents, employees, servants, licensees, and any subtenants and other persons, and all or any of its or their property therefrom, and repossess and enjoy the Premises, together with all Alterations thereto; but, in any event under this Section 19.2.1, Tenant shall remain liable as hereinafter provided. The words “re-enter” and “re-entry” as used

throughout this Article 19 are not restricted to their technical legal meanings. Landlord shall use commercially reasonable efforts to re-let the Premises following any such termination.

19.2.2 If this Lease is terminated or if Landlord shall re-enter the Premises as aforesaid, or in the event of the termination of this Lease, or of re-entry, by or under any proceeding or action or any provision of law by reason of a default hereunder on the part of Tenant beyond the applicable notice and cure periods, Tenant covenants and agrees forthwith to pay and be liable for, on the days originally fixed herein for the payment thereof, amounts equal to the installments of Base Rent, all Additional Rent and other charges reserved as they would, under the terms of this Lease, become due if this Lease had not been terminated or if Landlord had not entered or re-entered, as aforesaid, and whether the Premises be relet or remain vacant, in whole or in part, or for a period less than the remainder of the Term, or for the whole thereof, but, in the event the Premises be relet by Landlord, Tenant shall be entitled to a credit in the net amount of rent and other charges received by Landlord in reletting, after deduction of all reasonable expenses incurred in reletting the Premises (including, without limitation, remodeling costs, brokerage fees and the like), and in collecting the rent in connection therewith, in the following manner: Amounts

received by Landlord after reletting shall first be applied against such Landlord’s reasonable re-letting expenses, until the same are recovered, and until such recovery, Tenant shall pay, as of each day when a payment would fall due under this Lease, the amount which Tenant is obligated to pay under the terms of this Lease (Tenant’s liability prior to any such reletting and such recovery shall not in any way be diminished as a result of the fact that such reletting might be for a rent higher than the rent provided for in this Lease); when and if such reletting expenses have been completely recovered, the amounts received from reletting by Landlord as have not previously been applied shall be credited against Tenant’s obligations as of each day when a payment would fall due under this Lease, and only the net amount thereof shall be payable by Tenant. Further, Tenant shall not be entitled to any credit of any kind for any period after the date when the term of this Lease is scheduled to expire according to its terms.

19.2.3 Landlord may elect, as an alternative, accelerate the Rent payable under this Lease if this Lease is terminated as a result of Tenant’s default beyond the applicable notice and cure periods and have Tenant pay liquidated damages, which election may be made by notice given to Tenant at any time following the effective termination date of this Lease under Section 19.2.1 above, and whether or not Landlord shall have collected any damages as hereinbefore provided in this Article 19, and in lieu of all other such damages beyond the date of such notice. Upon such notice, Tenant shall promptly pay to Landlord, as liquidated damages, in addition to any damages collected or due from Tenant from any period prior to such notice and all expenses which Landlord may have incurred with respect to the collection of such damages, such a sum as at the time of such notice represents the amount of the excess, if any, of (a) the discounted present value, using the Federal Reserve discount rate (or equivalent), of the Base Rent, Additional Rent and other charges which would have been payable by Tenant under this Lease for the remainder of the Term if the Lease terms had been fully complied with by Tenant, over and above (b) the discounted present value, using the Federal Reserve discount rate (or equivalent), of the Base Rent, Additional Rent and other charges that would be received by Landlord if the Premises were re-leased at the time of such notice for the remainder of the Term at the fair market value (including provisions regarding periodic increases in Base Rent if such are applicable) prevailing at the time of such notice. For the purposes of this Article 19, if Landlord elects to require Tenant to pay liquidated damages in accordance with this Section 19.2.3, the total Rent shall be computed by assuming the Landlord’s Operating Expenses, Tax Expenses and Utilities Costs to be the same as were payable for the twelve (12) calendar months (or if less than twelve (12) calendar months have been elapsed since the date hereof, the partial year) immediately preceding such termination or re-entry. For the avoidance of doubt, Landlord shall not be entitled to double count for any amounts previously paid by Tenant.

19.2.4 Nothing contained in this Lease shall limit or prejudice the right of Landlord to prove for and obtain in proceedings for bankruptcy or insolvency by reason of the termination of this Lease, an amount equal to the maximum allowed by any statute or rule of law in effect at the time when, and governing the proceeds in which, the damages are to be proved, whether or not the amount be greater, equal to, or less than the amount of the loss or damages referred to above.

19.2.5 In the event of any default beyond the notice and cure periods set forth above, Landlord may, but shall not be obligated to, make any such payment or perform or otherwise cure any such obligation, provision, covenant or condition on Tenant’s part to be observed or performed (and may enter the Premises for such purposes). In the event of Tenant’s failure to perform any of its obligations or covenants under this Lease, and such failure to perform poses an immediate material risk of injury or harm to persons or damage to or loss of property, then Landlord shall have the right to cure or otherwise perform such covenant or obligation at any time after such failure to perform by Tenant, whether or not any such notice or cure period set forth in Section 19.1 above has expired. Any such actions undertaken by Landlord pursuant to the foregoing provisions of this Section 19.2.5 shall not be deemed a waiver of Landlord’s rights and remedies as a result of Tenant’s failure to perform and shall not release Tenant from any of its obligations under this Lease.

19.3 Payment by Tenant. Tenant shall pay to Landlord, within thirty (30) days after delivery by Landlord to Tenant of statements therefor: (i) sums equal to expenditures reasonably made and obligations incurred by Landlord in connection with Landlord’s performance or cure of any of Tenant’s obligations pursuant to the provisions of Section 19.2.5 above; and (ii) sums equal to all expenditures made and obligations incurred by Landlord in collecting or attempting to collect the delinquent Rent or in successfully enforcing any rights of Landlord under this Lease or pursuant to law following a Tenant default, including, without limitation, all legal fees and other amounts so expended. Tenant’s obligations under this Section 19.3 shall survive the expiration or sooner termination of the Lease Term.

19.4 Sublessees of Tenant. If Landlord terminates this Lease on account of any default by Tenant, as set forth in this Article 19, Landlord shall have the right to terminate any and all subleases, licenses, concessions or other consensual arrangements for possession entered into by Tenant and affecting the Premises or may, in Landlord’s sole discretion, succeed to Tenant’s interest in such subleases, licenses, concessions or arrangements. If Landlord elects to succeed to Tenant’s interest in any such subleases, licenses, concessions or arrangements, Tenant shall, as of the date of notice by Landlord of such election, have no further right to or interest in the rent or other consideration receivable thereunder.

19.5 Waiver of Default. No waiver by Landlord of any violation or breach by Tenant of any of the terms, provisions and covenants herein contained shall be deemed or construed to constitute a waiver of any other or later violation or breach by Tenant of the same or any other of the terms, provisions, and covenants herein contained. Forbearance by Landlord in enforcement of one or more of the remedies herein provided upon a default by Tenant shall not be deemed or construed to constitute a waiver of such default. The acceptance of any Rent hereunder by Landlord following the occurrence of any default, whether or not known to Landlord, shall not be deemed a waiver of any such default, except only a default in the payment of the Rent so accepted. No waiver by Tenant of any violation or breach by Landlord of any of the terms, provisions and covenants herein contained shall be deemed or construed to constitute a waiver of any other or later violation or breach by Landlord of the same or any other of the terms, provisions, and covenants herein contained.

19.6 Efforts to Relet. For the purposes of this Article 19, Tenant’s right to possession shall not be deemed to have been terminated by efforts of Landlord to relet the Premises, by its acts of maintenance or preservation with respect to the Premises, or, to the extent permitted by applicable law, by appointment of a receiver to protect Landlord’s interests hereunder. The foregoing enumeration is not exhaustive, but merely illustrative of acts which may be performed by Landlord without terminating Tenant’s right to possession.

19.7 Bankruptcy. In the event a debtor, trustee or debtor in possession under the Bankruptcy Code, or another person with similar rights, duties and powers under any other applicable laws, proposes to cure any default under this Lease or to assume or assign this Lease and is obliged to provide adequate assurance to Landlord that (a) a default shall be cured, (b) Landlord shall be compensated for its damages arising from any breach of this Lease and (c) future performance of Tenant’s obligations under this Lease shall occur, then such adequate assurances shall include any or all of the following, as designated by Landlord in its sole and absolute discretion:

Subject to Section 20.9 below, Tenant shall deliver to Landlord, within five (5) business days of Tenant’s execution of this Lease, an unconditional, clean, irrevocable letter of credit (the “L-C”) in the amount set forth in Section 20.3 below (the “L-C Amount”), which L-C shall be issued by a money-center, solvent and nationally or regionally recognized bank (a bank which accepts deposits, maintains accounts, which will negotiate a letter of credit, and whose deposits are insured by the FDIC) reasonably acceptable to Landlord (such approved, issuing bank being referred to herein as the “Bank”), and which L-C shall be in the form of Exhibit E attached hereto (or such other form approved by Landlord). Landlord hereby approves First Republic Bank as the Bank. Tenant shall pay all expenses, points and/or fees incurred by Tenant in obtaining the L-C. The L-C shall (i) be “drawable” at sight, irrevocable and unconditional, (ii) be maintained in effect, whether through renewal or extension, for the period commencing on the date of this Lease and continuing until the date (the “L-C Expiration Date”) that is no less than sixty (60) days after the expiration of the Lease Term as the same may be extended or earlier termination, and Tenant shall deliver a new L-C or certificate or amendment of renewal or extension to Landlord at least thirty (30) days prior to the expiration of the L-C then held by Landlord (unless the same automatically renews), without any action whatsoever on the part of Landlord, (iii) be fully assignable by Landlord, its successors and assigns, (iv) permit partial draws and multiple presentations and drawings, and (v) be otherwise subject to the International Standby Practices-ISP 98, International Chamber of Commerce Publication #590. Landlord, or its then managing agent, shall have the right to draw down an amount up to the face amount of the L-C if any of the following shall have occurred or be applicable: (A) a default of Tenant has occurred (beyond any applicable notice, grace, or cure periods) or (B) the Lease has been rejected, or is deemed rejected, under Section 365 of the U.S. Bankruptcy Code, following the filing of a voluntary petition by Tenant under the Bankruptcy Code, or the filing of an involuntary petition against Tenant under the Bankruptcy Code, or (C) the Bank has notified Landlord that the L-C will not be renewed or extended through the L-C Expiration Date (each of the foregoing being an “L-C Draw Event”). All amounts drawn will be held as a cash security deposit under Section 20.9. The L-C shall be honored by the Bank regardless of whether Tenant disputes Landlord’s right to draw upon the L-C. In addition, in the event the Bank is placed into receivership or conservatorship by the Federal Deposit Insurance Corporation or any successor or similar entity, then, effective as of the date such receivership or conservatorship occurs, said L-C shall be deemed to fail to meet the requirements of this Article 21, and, within ten (10) business days following Landlord’s notice to Tenant of such receivership or conservatorship (the “L-C FDIC Replacement Notice”), Tenant shall replace such L-C with a substitute letter of credit from a different issuer otherwise acceptable to Landlord in its reasonable discretion and that complies in all respects with the requirements of this Article 20 or deposit cash with Landlord pursuant to Section 20.9. If Tenant fails to replace such L-C with such conforming, substitute letter of credit pursuant to the terms and conditions of this Section 20.1, then, notwithstanding anything in this Lease to the contrary, Landlord shall have the right to draw the full amount of the L-C and hold it as a cash security deposit per Section 20.9. In the event of an assignment by Tenant of its interest in the Lease (and irrespective of whether Landlord’s consent is required for such assignment), the acceptance of any replacement or substitute letter of credit by Landlord from the assignee shall be subject to Landlord’s prior written approval, in Landlord’s sole and absolute discretion provided if Landlord does not approve, then the security may be posted in cash as set forth in Section 20.9, following which Landlord will promptly return the L-C to Tenant.

20.2 Application of L-C. Tenant hereby acknowledges and agrees that Landlord is entering into this Lease in material reliance upon the ability of Landlord to draw upon the L-C upon the occurrence of any L-C Draw Event. In the event of any L-C Draw Event under Section 20.1(A) or (B) above, Landlord may, but without obligation to do so, and without notice to Tenant, draw upon the L-C, in part or in whole, to cure any such L-C Draw Event and/or to compensate Landlord for any and all damages of any kind or nature sustained or which Landlord reasonably estimates that it will sustain resulting from Tenant’s breach or default of the Lease or other L-C Draw Event and/or to compensate Landlord for any and all damages arising out of, or incurred in connection with, the termination of this Lease. The use, application or retention of the L-C, or any portion thereof, by Landlord shall not prevent Landlord from exercising any other right or remedy provided by this Lease or by any applicable law, it being intended that Landlord shall not first be required to proceed against the L-C, and such L-C shall not operate as a limitation on any recovery

to which Landlord may otherwise be entitled. Tenant agrees not to interfere in any way with payment to Landlord of the proceeds of the L-C, either prior to or following a “draw” by Landlord of any portion of the L-C, regardless of whether any dispute exists between Tenant and Landlord as to Landlord’s right to draw upon the L-C. No condition or term of this Lease shall be deemed to render the L-C conditional to justify the issuer of the L-C in failing to honor a drawing upon such L-C in a timely manner. Tenant agrees and acknowledges that (i) the L-C constitutes a separate and independent contract between Landlord and the Bank, (ii) Tenant is not a third party beneficiary of such contract, (iii) Tenant has no property interest whatsoever in the L-C or the proceeds thereof, and (iv) in the event Tenant becomes a debtor under any chapter of the Bankruptcy Code, Tenant is placed into receivership or conservatorship, and/or there is an event of a receivership, conservatorship or a bankruptcy filing by, or on behalf of, Tenant, neither Tenant, any trustee, nor Tenant’s bankruptcy estate shall have any right to restrict or limit Landlord’s claim and/or rights to the L-C and/or the proceeds thereof by application of Section 502(b)(6) of the U. S. Bankruptcy Code or otherwise.

20.3 L-C Amount; Maintenance of L-C by Tenant; Liquidated Damages.

20.3.1 L-C Amount. The initial L-C Amount shall be equal to the amount set forth in Section 10 of the Summary.

20.3.2 Reduction of L-C Amount. To the extent that Tenant is not in default under this Lease (beyond the applicable notice and cure period set forth in this Lease) (the “LC Reduction Contingency”), the L-C Amount shall be reduced as follows:


Date of Reduction	L-C Amount
24^th Month Anniversary of Lease Commencement Date	$	1,917,759.40

Notwithstanding anything to the contrary set forth in this Section 20.3.2, in no event shall the L-C Amount as set forth above decrease during any period in which Tenant is in default under this Lease and/or in the event the LC Reduction Contingency is not satisfied, but such decrease shall take place retroactively after such default is cured and/or after the LC Reduction Contingency is satisfied, provided that no such decrease shall thereafter take effect in the event this Lease is terminated early due to such default by Tenant.

20.3.3 In General. If, as a result of any drawing by Landlord of all or any portion of the L-C, the amount of the L-C shall be less than the L-C Amount, Tenant shall, within five (5) days thereafter, provide Landlord with additional letter(s) of credit (or cash security to be held pursuant to Section 20.9) in an amount equal to the deficiency, and any such additional letter(s) of credit shall comply with all of the provisions of this Article 20, and if Tenant fails to comply with the foregoing, the same shall be subject to the terms of Section 20.3.3 below. Tenant further covenants and warrants that it will neither assign nor encumber the L-C or any part thereof and that neither Landlord nor its successors or assigns will be bound by any such assignment, encumbrance, attempted assignment or attempted encumbrance. Without limiting the generality of the foregoing, if the L-C expires earlier than the L-C Expiration Date, Landlord will accept a renewal thereof (such renewal letter of credit to be in effect and delivered to Landlord, as applicable, not later than ten (10) business days prior to the expiration of the L-C), which shall be irrevocable and automatically renewable as above provided through the L-C Expiration Date upon the same terms as

- 35 -

908728.01/SD

374622.00146/4-30-21/MLT/bp

ActiveUS 186012966v.2

the expiring L-C or such other terms as may be acceptable to Landlord in its sole discretion. As an express condition to Tenant’s right to extend the Term of this Lease pursuant to the Extension Option Rider, Tenant shall, not later than thirty (30) days prior to the commencement of the Option Term, deliver to Landlord a new L-C or certificate or amendment of renewal or extension evidencing the L-C Expiration Date as thirty (30) days after the expiration of the Option Term unless the L-C automatically renews (the “Extension Option L-C Condition”). However, if the L-C is not timely renewed, or if Tenant fails to maintain the L-C in the amount and in accordance with the terms set forth in this Article 20, Landlord shall have the right to present the L-C to the Bank in accordance with the terms of this Article 20, and the proceeds of the L-C shall be held as a cash security deposit under Security 20.9 and may be applied by Landlord against any Rent payable by Tenant under this Lease that is not paid when due and/or to pay for all losses and damages that Landlord has suffered or that Landlord reasonably estimates that it will suffer as a result of any breach or default by Tenant under this Lease which continues beyond applicable notice and cure periods. In the event Landlord elects to exercise its rights under the foregoing item (x), (I) any unused proceeds shall be held as a cash security deposit under Section 20.9 and need not be segregated from Landlord’s other assets, and (II) Landlord agrees to pay to Tenant within thirty (30) days after the L-C Expiration Date the amount of any proceeds of the L-C received by Landlord and not applied against any Rent payable by Tenant under this Lease that was not paid when due or used to pay for any losses and/or damages suffered by Landlord (or reasonably estimated by Landlord that it will suffer) as a result of any breach or default by Tenant under this Lease; provided, however, that if prior to the L-C Expiration Date a voluntary petition is filed by Tenant, or an involuntary petition is filed against Tenant by any of Tenant’s creditors, under the Bankruptcy Code, then Landlord shall not be obligated to make such payment in the amount of the unused L-C proceeds until either all preference issues relating to payments under this Lease have been resolved in such bankruptcy or reorganization case or such bankruptcy or reorganization case has been dismissed.

20.3.4 Intentionally Omitted.

20.4 Transfer and Encumbrance. The L-C shall also provide that Landlord may, at any time and without notice to Tenant and without first obtaining Tenant’s consent thereto, transfer (one or more times) all or any portion of its interest in and to the L-C to another party, person or entity, that purchases the Project and becomes the Landlord under the Lease. In the event of a transfer of Landlord’s interest in under this Lease, Landlord shall transfer the L-C, in whole or in part, to the transferee and thereupon Landlord shall, without any further agreement between the parties, be released by Tenant from all liability therefor, and it is agreed that the provisions hereof shall apply to every transfer or assignment of the whole of said L-C to a new landlord. In connection with any such transfer of the L-C by Landlord, Tenant shall, at Tenant’s sole cost and expense, execute and submit to the Bank such applications, documents and instruments as may be necessary to effectuate such transfer and, Tenant shall be responsible for paying the Bank’s transfer and processing fees in connection therewith; provided that, Landlord shall have the right (in its sole discretion), but not the obligation, to pay such fees on behalf of Tenant, in which case Tenant shall reimburse Landlord within ten (10) days after Tenant’s receipt of an invoice from Landlord therefor.

20.5 L-C Not a Security Deposit. Tenant hereby irrevocably waives and relinquishes the provisions of law, now or hereafter in effect, which (x) establish the time frame by which a landlord must refund a security deposit under a lease, and/or (y) provide that a landlord may claim from a security deposit only those sums reasonably necessary to remedy defaults in the payment of rent, to repair damage caused by a tenant or to clean the premises, it being agreed that Landlord may, in addition, claim those sums specified in this Article 20 and/or those sums reasonably necessary to (a) compensate Landlord for any loss or damage caused by Tenant’s breach of this Lease to which Landlord is entitled under the Lease, including any damages Landlord suffers following termination of this Lease, and/or (b) compensate Landlord for any and all damages arising out of, or incurred in connection with, the termination of this Lease to which Landlord is entitled under the Lease.

20.6 Non-Interference by Tenant. Tenant agrees not to interfere in any way with any payment to Landlord of the proceeds of the L-C, either prior to or following a “draw” by Landlord of all or any portion of the L-C, regardless of whether any dispute exists between Tenant and Landlord as to Landlord’s right to draw down all or any portion of the L-C. No condition or term of this Lease shall be deemed to render the L-C conditional and thereby afford the Bank a justification for failing to honor a drawing upon such L-C in a timely manner. Tenant shall not request or instruct the Bank of any L-C to refrain from paying sight draft(s) drawn under such L-C.

ActiveUS 186012966v.2

20.7 Waiver of Certain Relief. Tenant unconditionally and irrevocably waives (and as an independent covenant hereunder, covenants not to assert) any right to claim or obtain any of the following relief in connection with the L-C:

20.7.1 A temporary restraining order, temporary injunction, permanent injunction, or other order that would prevent, restrain or restrict the presentment to Landlord of sight drafts drawn under any L-C or the Bank’s honoring or payment of sight draft(s) to Landlord; or

20.7.2 Any attachment, garnishment, or levy in any manner upon either the proceeds of any L-C or the obligations of the Bank (either before or after the presentment to the Bank of sight drafts drawn under such L-C) based on any theory whatever.

20.8 Remedy for Improper Drafts. Tenant’s sole remedy in connection with the improper presentment or payment of sight drafts drawn under any L-C shall be the right to obtain from Landlord a refund of the amount of any sight draft(s) that were improperly presented or the proceeds of which were misapplied, together with interest at the Interest Rate and reasonable actual out-of-pocket attorneys’ fees, provided that at the time of such refund, Tenant increases the amount of such L-C to the amount (if any) then required under the applicable provisions of this Lease. Tenant acknowledges that the presentment of sight drafts drawn under any L-C, or the Bank’s payment of sight drafts drawn under such L-C, could not under any circumstances cause Tenant injury that could not be remedied by an award of money damages, and that the recovery of money damages would be an adequate remedy therefor. In the event Tenant shall be entitled to a refund as aforesaid and Landlord shall fail to make such payment within ten (10) business days after demand, Tenant shall have the right to deduct the amount thereof together with interest thereon at the Interest Rate from the next installment(s) of Base Rent.

20.9 Security Deposit. If Tenant does not elect to deposit the L-C, then Tenant shall, concurrent with Tenant’s execution of this Lease, deposit with Landlord a security deposit (the “Security Deposit”) in the amount set forth in Section 10 of the Summary. The Security Deposit shall be held by Landlord as security for the faithful performance by Tenant of all the terms, covenants, and conditions of this Lease to be kept and performed by Tenant during the Lease Term. If Tenant defaults (beyond any applicable notice and cure periods) with respect to any provisions of this Lease, including, but not limited to, the provisions relating to the payment of Rent, Landlord may, but shall not be required to, use, apply or retain all or any part of the Security Deposit for the payment of any Rent or any other sum in default, or to compensate Landlord for any other actual loss or damage caused by Tenant’s default. If any portion of the Security Deposit is so used or applied, Tenant shall, within ten (10) business days after written demand therefor, deposit cash with Landlord in an amount sufficient to restore the Security Deposit to its original amount, and Tenant’s failure to do so shall be a default under this Lease. The Security Deposit, or any balance thereof, shall be returned to Tenant within sixty (60) days following the expiration of the Lease Term; provided Tenant has cured any outstanding defaults or, if not, Landlord shall return the Security Deposit less amounts required to cure outstanding defaults. Tenant shall not be entitled to any interest on the Security Deposit. Tenant hereby waives all provisions of law, now or hereafter in force, which provide that Landlord may claim from a security deposit only those sums reasonably necessary to remedy defaults in the payment of rent, to repair damage caused by Tenant or to clean the Premises, it being agreed that Landlord may, in addition, claim those sums reasonably necessary to compensate Landlord for any other loss or damage to which Landlord is entitled to under the Lease, foreseeable or unforeseeable, caused by the act or omission of Tenant or any officer, employee, agent or invitee of Tenant to the extent permitted under the Lease. In the event of bankruptcy or other debtor-creditor proceedings against Tenant, the Security Deposit shall be deemed to be applied first to the payment of Rent and other charges due Landlord for all periods prior to the filing of such proceedings. Notwithstanding anything to the contrary contained in this Article 20 or Section 10 of the Summary, in the event that Tenant, at the expiration of the twenty-fourth (24^th) month of the initial Lease Term (“Reduction Date”), is not in default of any of its obligations under this Lease (beyond the expiration of all applicable notice and cure periods) and Landlord has not made any application of the Security Deposit prior to the Reduction Date, Landlord shall reduce the amount of the Security Deposit to an amount equal to One Million Five Hundred Thirty-Four Thousand Two Hundred Seven and 50/100 Dollars ($1,534,207.50) and Landlord shall, within ten (10) days after the Reduction Date, refund to Tenant an amount equal to Seven Hundred Sixty-Seven Thousand One Hundred Three and 70/100 Dollars ($767,103.70).

20.10 Conversion of L-C/Security Deposit. Tenant shall have the right to convert the L-C to a Security Deposit and the Security Deposit to an L-C up to two (2) times in the aggregate during the Lease Term. In the event Tenant initially provides an L-C pursuant to this Article 20, then the providing of such L-C shall not apply to the two (2) time limit. Tenant agrees to pay Landlord’s reasonable attorney’s fees in connection with any such conversion(s).

ARTICLE 21

COMPLIANCE WITH LAW

Tenant shall not do anything or suffer anything to be done in or about the Premises which will in any way violate with any applicable law, statute, ordinance or other governmental rule, regulation or requirement now in force or which may hereafter be enacted or promulgated. At its sole cost and expense, Tenant shall promptly comply with all such governmental measures, other than the making of structural changes, changes to the Building’s systems or adding new Building systems, such as life safety system, or changes or additions on account of such governmental measures in effect on the Lease Commencement Date (collectively the “Excluded Changes”); provided, however, to the extent such Excluded Changes are required due to or triggered by Tenant’s improvements or alterations to and/or manner of Tenant’s specific use of the Premises (as opposed to the Permitted Uses generally), Landlord shall perform such work, at Tenant’s cost (which shall be paid by Tenant to Landlord within thirty (30) days after Tenant’s receipt of invoice therefor from Landlord). Landlord shall otherwise perform all Excluded Changes at Landlord’s sole cost (and not as an Operating Expense to the extent changes or additions are required to comply with governmental measures in effect on the Lease Commencement Date). The non-applicable judgment of any court of competent jurisdiction or the admission of Tenant in any judicial action, regardless of whether Landlord is a party thereto, that Tenant has violated any of said governmental measures, shall be conclusive of that fact as between Landlord and Tenant.

ARTICLE 22

ENTRY BY LANDLORD

Landlord reserves the right at all reasonable times and upon reasonable advance written notice (at least 24 hours), to Tenant to enter the Premises to: (i) inspect them; (ii) show the Premises to prospective purchasers, mortgagees, the ground lessors, or, during the last 9 months of the Lease Term, prospective tenants; (iii) to post notices of nonresponsibility; or (iv) provided the same does not have an adverse impact on Tenant’s use to enjoyment of the Premises, alter, improve or repair the Premises or the Building if necessary to comply with current building codes or other applicable laws, or for structural alterations, repairs or improvements to the Building. Notwithstanding anything to the contrary contained in this Article 22, Landlord may enter the Premises at any time, without notice to Tenant (provided with respect to emergency situations, notice of such entry shall be made promptly thereafter), in emergency situations and/or to perform janitorial required of Landlord pursuant to this Lease. Any such entries in compliance with this Section shall be without the abatement of Rent and shall include the right to take such reasonable steps as required to accomplish the stated purposes. Tenant hereby waives any claims for damages or for any injuries or inconvenience to or interference with Tenant’s business, any loss of occupancy or quiet enjoyment of the Premises, and any other loss occasioned thereby, except to the extent caused by the negligence or willful misconduct of Landlord or any Landlord Party (provided, the foregoing proviso shall not apply to loss of profits or other consequential damages). For each of the above purposes, Landlord shall at all times have a key with which to unlock all the doors in the Premises, excluding Tenant’s vaults, safes and special security areas designated in advance by Tenant. In an emergency, Landlord shall have the right to enter without notice and use any means that Landlord may deem proper to open the doors in and to the Premises. Any entry into the Premises in the manner hereinbefore described shall not be deemed to be a forcible or unlawful entry into, or a detainer of, the Premises, or an actual or constructive eviction of Tenant from any portion of the Premises. In connection with such accessing of the Premises, Landlord will comply with Tenant’s reasonable written security measures so long as such compliance does not materially impede or delay Landlord’s access to the Premises. Landlord shall in all events use commercially reasonable efforts to minimize any interference with Tenant’s use and enjoyment of, and access to, the Premises in connection with any exercise of rights by Landlord under this Section 22.

ARTICLE 23

PARKING

Throughout the Lease Term, Tenant shall have the exclusive right to use, free of charges, the number of parking spaces set forth in Section 12 of the Summary, which parking spaces constitute the entirety of the parking under the Building and the adjacent surface parking, being all of the parking in the Project. Tenant shall comply with the Parking Rules and Regulations which are in effect on the date hereof, as set forth in the attached Exhibit D and all reasonable modifications and additions thereto which are prescribed from time to time for the orderly operation and use of the Parking Areas by Landlord, and/or Landlord’s Parking Operator (as defined below); provided that such modifications or alterations do not effect Tenant’s use of or access to the Parking Areas. Landlord specifically reserve the right to change the size, configuration, design, layout, of the Parking Areas, and Tenant acknowledges and agrees that Landlord may, without incurring any liability to Tenant and without any abatement of Rent under this Lease, from time to time, temporarily close-off or restrict access to the Parking Areas, so long as Tenant retains access to the number of parking spaces set forth in Section 12 of the Summary. Landlord may delegate its responsibilities hereunder to a parking operator (the “Parking Operator”) in which case the Parking Operator shall have all the rights of control attributed hereby to Landlord. Any parking tax or other charges imposed by governmental authorities in connection with the use of such parking shall be paid directly by Tenant or the parking users, or, if directly imposed against Landlord, Tenant shall reimburse Landlord for all such taxes and/or charges within thirty (30) days after Landlord’s demand therefor. The parking rights provided to Tenant pursuant to this Article 23 are provided solely for use by Tenant’s own personnel visitors and invitees and such rights may not be transferred, assigned, subleased or otherwise alienated by Tenant without Landlord’s prior approval, except in connection with an assignment of this Lease or sublease of the Premises made in accordance with Article 14 above.

ARTICLE 24

MISCELLANEOUS PROVISIONS

24.1 Terms; Captions. The necessary grammatical changes required to make the provisions hereof apply either to corporations or partnerships or individuals, men or women, as the case may require, shall in all cases be assumed as though in each case fully expressed. The captions of Articles and Sections are for convenience only and shall not be deemed to limit, construe, affect or alter the meaning of such Articles and Sections.

24.2 Binding Effect. Each of the provisions of this Lease shall extend to and shall, as the case may require, bind or inure to the benefit not only of Landlord and of Tenant, but also of their respective successors or assigns, provided this clause shall not permit any assignment by Tenant contrary to the provisions of Article 14 above.

24.3 No Waiver. No waiver of any provision of this Lease shall be implied by any failure of a party to enforce any remedy on account of the violation of such provision, even if such violation shall continue or be repeated subsequently, any waiver by a party of any provision of this Lease may only be in writing, and no express waiver shall affect any provision other than the one specified in such waiver and that one only for the time and in the manner specifically stated. No receipt of monies by Landlord from Tenant after the termination of this Lease shall in any way alter the length of the Lease Term or of Tenant’s right of possession hereunder or after the giving of any notice shall reinstate, continue or extend the Lease Term or affect any notice given Tenant prior to the receipt of such monies, it being agreed that after the service of notice or the commencement of a suit or after final judgment for possession of the Premises, Landlord may receive and collect any Rent due, and the payment of said Rent shall not waive or affect said notice, suit or judgment.

24.4 Modification of Lease. If Landlord or any such current or prospective mortgagee or ground lessor require execution of a short form of Lease for recording, containing, among other customary provisions, the names of the parties, a description of the Premises and the Lease Term, Tenant shall execute such short form of Lease and to deliver the same to Landlord within fifteen (15) days following the request therefor.

24.5 Transfer of Landlord’s Interest. Landlord has the right to transfer all or any portion of its interest in the Project, the Building and/or in this Lease, and upon any such transfer, Landlord shall automatically be released from all liability under this Lease thereafter accruing and Tenant shall look solely to such transferee for the performance of Landlord’s obligations hereunder after the date of transfer so long as the transferee has assumed all of Landlord’s obligations hereunder. The liability of any transferee of Landlord shall be limited to the interest of such transferee in the Project and such transferee shall be without personal liability under this Lease beyond its interest in the Project, and Tenant hereby expressly waives and releases such personal liability on behalf of itself and all persons claiming by, through or under Tenant. Landlord may also assign its interest in this Lease to a mortgage lender as additional security but such assignment shall not release Landlord from its obligations hereunder and Tenant shall continue to look to Landlord for the performance of its obligations hereunder. Neither Landlord (beyond its interest in the Project) nor any of its affiliates, nor any of their respective partners, shareholders, directors, officers, employees, members or agents shall be personally liable for Landlord’s obligations or any deficiency under this Lease, and service of process shall not be made against any shareholder, member, director, officer, employee or agent of Landlord or any of Landlord’s affiliates except as appropriate to serve Landlord. No partner, shareholder, director, officer, employee, member or agent of Landlord or any of its affiliates shall be sued for liabilities of Landlord or named as a party in any suit or action for liabilities of Landlord, and service of process shall not be made against any partner or member of Landlord except as may be necessary to serve or secure jurisdiction of the partnership, joint venture or limited liability company, as applicable. No judgment shall be taken or writ of execution levied against any partner, shareholder, director, officer, employee, member or agent of Landlord or any of its affiliates. Landlord’s interest in the Project shall include the proceeds therefrom.

24.6 Prohibition Against Recording. Except as provided herein, this Lease shall not be recorded by Tenant or by anyone acting through, under or on behalf of Tenant, and the recording thereof in violation of this provision shall make this Lease null and void at Landlord’s election. Simultaneously with the execution of this Lease, Landlord and Tenant shall enter into a recordable notice of lease in the form of Exhibit G, which Landlord, at Landlord’s expense, shall then cause to be recorded in the applicable public record(s) within five (5) business days after the execution of this Lease.

24.7 Landlord’s Title; Air Rights. Landlord’s title is and always shall be paramount to the title of Tenant. Nothing herein contained shall empower Tenant to do any act which can, shall or may encumber the title of Landlord, other than the granting of the leasehold and other rights set forth herein. No rights to any view or to light or air over any property, whether belonging to Landlord or any other person, are granted to Tenant by this Lease.

24.8 Tenant’s Signs.

24.8.1 General. Tenant shall be entitled, at Tenant’s sole cost and expense and without Landlord’s further approval, to display signage in the interior of the Premises. Upon the expiration or earlier termination of this Lease, Tenant shall be responsible, at its sole cost and expense, for the removal of such signage and the repair of all damage to the Building caused by such removal.

24.8.2 Exterior Signage. Subject to this Section 24.8.2, Tenant shall be entitled to install, at its sole cost and expense, exclusive signage on the Building and exterior of the Project (“Signage”). The graphics, materials, size, color, design, lettering, lighting (if any), specifications and exact location of the Signage (collectively, the “Signage Specifications”) shall be subject to the prior written approval of Landlord, which approval shall not be unreasonably withheld, conditioned or delayed; provided that Tenant shall be entitled to a sign including its name, logo and trade dress in the maximize size permitted by applicable zoning codes. In addition, the Signage and all Signage Specifications therefore shall be subject to Tenant’s receipt of all required governmental permits and approvals, shall be subject to all applicable governmental laws and ordinances, and all covenants, conditions and restrictions affecting the Project. Tenant hereby acknowledges that, notwithstanding Landlord’s approval of the Signage and/or the Signage Specifications therefor, Landlord has made no representations or warranty to Tenant with respect to the probability of obtaining such approvals and permits. In the event Tenant does not receive the necessary permits and approvals for the Signage, Tenant’s and Landlord’s rights and obligations under the remaining provisions of this Lease shall not be affected. The cost of installation of the Signage, as well as all costs of design and construction of such Signage and all other costs associated with such Signage, including, without

limitation, permits, maintenance and repair, shall be the sole responsibility of Tenant. Notwithstanding anything to the contrary contained herein, in the event that at any time during the Term of this Lease (or any Option Term, if applicable), Tenant subleases more than thirty five percent (35%) of the Premises then Tenant’s right to the Signage shall thereupon terminate and Tenant shall remove such Signage as provided in this Section 24.8.2 below. The rights to the Signage shall be personal to the Original Tenant and its Affiliate Assignees and may not be transferred except in connection with a Transfer of this Lease. Should the Signage require maintenance or repairs as determined in Landlord’s reasonable judgment, Landlord shall have the right to provide written notice thereof to Tenant and Tenant shall cause such repairs and/or maintenance to be performed within thirty (30) days after receipt of such notice from Landlord at Tenant’s sole cost and expense. Should Tenant fail to perform such maintenance and repairs within the period described in the immediately preceding sentence, Landlord shall have the right to cause such work to be performed and to charge Tenant, as Additional Rent, for the cost of such work. Upon the expiration or earlier termination of this Lease (or the termination of Tenant’s Signage right as described above), Tenant shall, at Tenant’s sole cost and expense, cause the Signage to be removed from the exterior of the Project and shall cause the exterior of the Project to be restored to the condition existing prior to the placement of such Signage. If Tenant fails to remove such Signage and to restore the exterior of the Project as provided in the immediately preceding sentence within thirty (30) days following the expiration or earlier termination of this Lease (or the termination of Tenant’s Signage as provided above), then Landlord may perform such work, and all costs and expenses incurred by Landlord in so performing such work shall be reimbursed by Tenant to Landlord within ten (10) business days after Tenant’s receipt of invoice therefor. The immediately preceding sentence shall survive the expiration or earlier termination of this Lease. Any signs, notices, logos, pictures, names or advertisements which are installed and that have not been individually approved by Landlord may be removed without notice by Landlord at the sole expense of Tenant. Except as provided in this Section 24.8.2 above, Tenant may not install any signs on the exterior of the Project. Any signs, window coverings, or blinds (unless the same are located behind the Landlord approved window coverings for the Project), or other items visible from the exterior of the Premises or Project are subject to the prior approval of Landlord, in its sole discretion.

24.9 Relationship of Parties. Nothing contained in this Lease shall be deemed or construed by the parties hereto or by any third party to create the relationship of principal and agent, partnership, joint venturer or any association between Landlord and Tenant, it being expressly understood and agreed that neither the method of computation of Rent nor any act of the parties hereto shall be deemed to create any relationship between Landlord and Tenant other than the relationship of landlord and tenant.

24.10 Application of Payments. Landlord shall have the right to apply payments received from Tenant pursuant to this Lease, regardless of Tenant’s designation of such payments, to satisfy any obligations of Tenant hereunder, in such order and amounts as Landlord, in its sole discretion, may elect.

Landlord and Tenant specifically agree that the obligations of Tenant hereunder, including, without limitation, the obligation to pay Base Rent and Additional Rent, and the obligations of Landlord, are independent and not mutually dependent covenants and that the failure of Landlord to perform any obligation hereunder shall not justify or empower Tenant to withhold Rent, except as explicitly provided herein, or to terminate this Lease unless Landlord’s default constitutes a constructive eviction or except as explicitly provided herein. Landlord and Tenant each acknowledges and agrees that the independent nature of the obligations of Tenant hereunder represents fair, reasonable, and accepted commercial practice with respect to the type of property subject to this Lease, and that this Lease is the product of free and informed negotiation during which both Landlord and Tenant were represented by counsel skilled in negotiating and drafting commercial leases in Massachusetts, and that the acknowledgements and agreements contained herein are made with full knowledge of the holding in Wesson x.

Landlord agrees to hold the financial statements and any other information provided by Tenant to Landlord, and any information about Tenant’s business or activities in the Premises, in confidence using at least the same degree of care that Landlord uses to protect its own confidential information of a similar nature; provided, however, that Landlord may disclose the financial statements to Landlord’s auditors, attorneys, lenders, affiliates, prospective purchasers and investors as reasonably required in the ordinary course of Landlord’s operations, provided that Landlord such parties treat the information as confidential and Landlord remains responsible for any unpermitted disclosures by such third parties. Landlord may disclose such information without violating this section to the extent that disclosure is reasonably necessary (a) for Landlord to enforce its rights or defend itself under this Lease; (b) for required submissions to any state or federal regulatory body; or (c) for compliance with a valid order of a court or other governmental body having jurisdiction, or any law, statute, or regulation, provided that, other than in an emergency, before disclosing such information, Landlord shall give Tenant five business days’ prior notice of the same to allow Tenant to obtain a protective order or such other judicial relief.
