THIS INDENTURE OF LEASE (this “Lease”) is hereby made and entered into on the Execution Date by and between Landlord and Tenant.

This Lease and all of its terms, covenants, representations, warranties, agreements and conditions are in all respects subject and subordinate to that certain Amended and Restated Master Lease Agreement dated as of January 1, 2015 by and between MIT 281-295 Albany Street LLC (“Ground Lessor”), as landlord, and Landlord, as tenant (as it may be amended from time to time, the “Master Lease”).

Each reference in this Lease to any of the terms and titles contained in any Exhibit attached to this Lease shall be deemed and construed to incorporate the data stated under that term or title in such Exhibit. All capitalized terms not otherwise defined herein shall have the meanings ascribed to them as set forth in the Lease Summary Sheet which is attached hereto and incorporated herein by reference.

1.LEASE GRANT; TERM; APPURTENANT RIGHTS; EXCLUSIONS

1.1Lease Grant

Landlord hereby leases to Tenant, and Tenant hereby leases from Landlord, the Premises upon and subject to terms and conditions of this Lease, for a term of years commencing on the Commencement Date and, unless earlier terminated or extended pursuant to the terms hereof, ending on the Expiration Date (the “Initial Term”; the Initial Term and each of the Extension Terms, if duly exercised, are hereinafter collectively referred to as the “Term”).  Once the Commencement Date is determined, Landlord and Tenant shall execute an agreement confirming the Commencement Date and the Expiration Date, in substantially the form attached hereto as Exhibit 4.  ▇▇▇▇▇▇’s failure to execute and return any such agreement proposed by Landlord, or to provide written objection to the statements contained therein, within ten (10) business days after the date of Tenant’s receipt thereof, shall be deemed an approval by Tenant of Landlord’s determination of such dates as set forth therein.

1.2Extension Terms.

(a)Provided that the following conditions (the “Extension Conditions”), any or all of which may be waived by Landlord in its sole discretion, are satisfied: (i) Tenant, an Affiliated Entity (hereinafter defined) and/or a Successor (hereinafter defined) is/are then occupying at least seventy-five percent (75%) of the Premises; and (ii) there is no Event of Default (1) as of the date of an Extension Notice (hereinafter defined), and (2) at the commencement of an Extension Term (hereinafter defined), Tenant shall have the option to extend the Initial Term for two (2) additional consecutive terms of five (5) years each (each individually, an “Extension Term”, and collectively, the “Extension Terms”), commencing as of the expiration of the Initial Term.  Tenant must exercise each option to extend, if at all, by giving Landlord written notice (the “Extension Notice”) not earlier than fifteen (15) months and no later than twelve (12) months prior to the expiration of the Initial Term or the first Extension Term, as the case may be, time being of the essence in each instance.  Notwithstanding the foregoing, Landlord may nullify Tenant’s exercise of its option to extend the Term by written notice to Tenant (the “Nullification Notice”) if (A) on the date Landlord receives the Extension Notice, there is an event which, with the passage of time and/or the giving of notice, would constitute an Event of Default hereunder and (B) Tenant fails to cure such default within the applicable cure period set forth in Section 20.1 after receipt of the Nullification Notice.  Upon the satisfaction of the Extension Conditions and the timely giving of the Extension Notice without a subsequent nullification by Landlord, the Term shall be deemed extended upon all of the terms and conditions of this Lease, except that Base Rent during the each of the Extension Terms shall be calculated in accordance with this Section 1.2.  If Tenant fails to give a timely Extension Notice, as aforesaid, Tenant shall have no further right to extend the Initial Term.  Notwithstanding the fact that Tenant’s proper and timely exercise of such option to extend the Initial Term shall be self-executing, Tenant shall promptly execute a lease amendment reflecting such Extension Term after Tenant validly exercises its option, if such lease amendment is provided by Landlord.  The execution of such lease amendment shall not be deemed to waive any of the conditions to Tenant’s exercise of its rights under this Section 1.2.

 

---

 

(b)The Base Rent during the first Rent Year of the each of the Extension Terms (the “Extension Term RY1 Base Rent”) shall be determined in accordance with the process described hereafter.  Extension Term RY1 Base Rent shall be the greater of (i) one hundred three percent (103%) of Base Rent for the last Rent Year of the Initial Term or the first Extension Term, as applicable, or (ii) the fair market rental value of the Premises as of the commencement of the applicable Extension Term as determined in accordance with the process described below, for renewals of combination laboratory and office space in the East Cambridge/ Cambridgeport area of equivalent quality, size, utility and location, with the length of the Extension Term, the credit standing of Tenant and all other relevant factors to be taken into account.  Within thirty (30) days after receipt of an Extension Notice, Landlord shall deliver to Tenant written notice of its determination of the Extension Term RY1 Base Rent for the applicable Extension Term.  Tenant shall, within thirty (30) days after receipt of such notice, notify Landlord in writing whether Tenant accepts or rejects Landlord’s determination of the Extension Term RY1 Base Rent (“Tenant’s Response Notice”).  If Tenant fails timely to deliver ▇▇▇▇▇▇’s Response Notice, ▇▇▇▇▇▇▇▇’s determination of the Extension Term RY1 Base Rent shall be binding on Tenant.

(c)If and only if Tenant’s Response Notice is timely delivered to Landlord and indicates both that Tenant rejects Landlord’s determination of the Extension Term RY1 Base Rent and desires to submit the matter to the determination process described in this Section 1.2(c) (the “Determination Process”), then the Extension Term RY1 Base Rent shall be determined in accordance with the procedure set forth in this Section 1.2(c).  In such event, within ten (10) days after receipt by Landlord of Tenant’s Response Notice indicating Tenant’s desire to submit the determination of the Extension Term RY1 Base Rent to the Determination Process, Tenant and Landlord shall each notify the other, in writing, of their respective selections of an appraiser or broker (respectively, “Landlord’s Appraiser” and “Tenant’s Appraiser”).  Landlord’s Appraiser and Tenant’s Appraiser shall then jointly select a third appraiser or broker (the “Third Appraiser”) within ten (10) days of their appointment.  All of the appraisers or brokers selected shall be individuals with at least ten (10) consecutive years’ commercial appraisal or brokerage experience in the East Cambridge/Cambridgeport area, and, in the case of the Third Appraiser, shall not have acted in any capacity for either Landlord or Tenant within five (5) years of his or her selection.  The three appraisers or brokers shall determine the Extension Term RY1 Base Rent in accordance with the requirements and criteria set forth in Section 1.2(b) above, employing the method commonly known as Baseball Arbitration, whereby Landlord’s Appraiser and Tenant’s Appraiser each sets forth its determination of the Extension Term RY1 Base Rent as defined above, and the Third Appraiser must select one or the other (it being understood that the Third Appraiser shall be expressly prohibited from selecting a compromise figure). Landlord’s Appraiser and Tenant’s Appraiser shall deliver their determinations of the Extension Term RY1 Base Rent to the Third Appraiser within five (5) days of the appointment of the Third Appraiser and the Third Appraiser shall render his or her decision within ten (10) days after receipt of both of the other two determinations of the Extension Term RY1 Base Rent.  The Third Appraiser’s decision shall be binding on both Landlord and Tenant.  Each party shall bear the cost of its own appraiser or broker and the cost of the Third Appraiser shall be paid by the party whose determination is not selected.

(d)Commencing on the first day of the second Rent Year of each Extension Term, Base Rent shall increase annually by three percent (3%), effective as of the first day of each Rent Year.

1.3Notice of Lease

Neither party shall record this Lease, but each of the parties hereto agrees to join in the execution of a statutory notice of lease in substantially the form attached hereto as Exhibit 5, which notice of lease may be recorded by Tenant with the Middlesex South Registry of Deeds and/or filed with the Registry District of the Land Court, as appropriate (collectively, the “Registry”) at Tenant’s sole cost and expense.  If a notice of lease was previously recorded with the Registry, upon the expiration or earlier termination

2

---

 

of this Lease, Landlord shall deliver to Tenant a notice of termination of lease and Tenant shall promptly execute, acknowledge and deliver the same (together with any other instrument(s) that may be necessary in order to record and/or file the same with the Registry) to Landlord for Landlord’s execution and recordation with the Registry, which obligation shall survive the expiration or earlier termination of the Lease.  If ▇▇▇▇▇▇ fails to deliver the executed notice of termination of lease within ten (10) days of receipt thereof, time being of the essence, Tenant hereby appoints Landlord as ▇▇▇▇▇▇’s attorney-in-fact to execute the same, such appointment being coupled with an interest.

1.4Appurtenant Rights.

(a)Common Areas.  Subject to the terms of this Lease and the Rules and Regulations (hereinafter defined), Tenant shall have, as appurtenant to the Premises, rights to use  (i) the loading dock(s), elevators and stairways of the Building, (ii) the common walkways necessary for access to the Building, and (iii) the risers of the Building for the installation of tel/data conduits and cabling Property (such areas are hereinafter referred to as the “Common Areas”); and no other appurtenant rights or easements, except as provided in Section 1.4(b) below.

(b)Parking.  During the Term, commencing on the Commencement Date, Tenant shall have the exclusive right to use the entire surface lot serving the Building (the “Parking Area”), which consists of twenty-three (23) parking spaces (the “Parking Rights”), for the parking of passenger vehicles by Tenant’s employees and guests and the employees and guests of any transferee pursuant to a Transfer permitted by Article 13 of this Lease (“Permitted Pass Holders”).  Landlord shall provide twenty-three (23) parking passes, stickers, or other methods of access, as determined by Landlord and/or Landlord’s parking operator, to accommodate parking in the Parking Area to Tenant for Tenant’s use to provide to Permitted Pass Holders.  Tenant shall not sublet, assign, encumber, pledge or otherwise transfer the Parking Rights except in connection with a Transfer permitted by Article 13 of this Lease.  During the Term, commencing on the Commencement Date, Tenant shall pay Landlord (or at Landlord’s election, directly to the parking operator, if any) for the Parking Rights at the then-current prevailing rate, as such rate may vary from time to time.  As of the Execution Date, the monthly charge for parking is Two Hundred Fifty Dollars ($250) per parking space per month. Landlord shall deliver (or cause to be delivered) written notice to Tenant of any change in the monthly parking charge.  If, for any reason, Tenant shall fail timely to pay the charge for any of said Parking Passes, and if such default continues for ten (10) days after written notice thereof it shall constitute an Event of Default hereunder.  Use of the Parking Area will be subject to such reasonable rules and regulations as may be in effect from time to time (including Landlord’s right, without additional charge to Tenant above the prevailing rate for the Parking Rights, to institute a valet or attendant-managed parking system).  Tenant shall provide Landlord and/or the operator of the Parking Area with such information as may be reasonably requested, including a monthly identification roster listing for each Permitted Pass Holder, indicating the name of the employee and the make, color and registration number of the vehicle to be parked in the Parking Area.  Except to the extent prohibited by Legal Requirements, neither Landlord nor the operator of the Parking Area assumes any responsibility whatsoever for loss or damage due to casualty or theft or otherwise to any automobile (or to any personal property therein) accessing or using the Parking Area, howsoever caused, and Tenant agrees to notify each Permitted Pass Holder of such limitation of liability.  No bailment is intended or shall be created by the provision of, or use of, the parking privileges described herein.  Notwithstanding anything to the contrary contained herein, in the event the Landlord elects to use the Parking Area for non-parking purposes Landlord shall have the right to relocate the parking privileges from time to time to parking areas at other properties owned, leased or controlled by Landlord or its affiliates, so long as such other property is within 1,000 feet of the Land, in which case such relocated parking areas shall be deemed the “Parking Area” for purposes of this Lease.  In addition to the foregoing, Landlord shall use commercially reasonable efforts to make available to Tenant up to twelve (12) additional parking spaces (the “Off Site Parking Spaces”) in one or more parking areas owned or

3

---

 

controlled by Landlord or its affiliates in the vicinity of the Building to the extent such additional parking spaces are available.  Tenant shall pay the monthly parking fee then being charged by the owner(s) or operator(s) of such Off Site Parking Spaces, as may be adjusted from time to time upon prior written notice to Tenant, directly to such owner(s) or operator(s), or as may otherwise be directed in writing by Landlord.  Landlord reserves the right to terminate Tenant’s right to use any or all of the Off Site Parking Spaces upon prior written notice to Tenant in the event the owner of any Off Site Parking Spaces elects to use such Off Site Parking Spaces for non-parking purposes or if such Off Site Parking spaces become unavailable to Landlord.

(c)Roof.  Tenant may use those portions of the Building identified as a “Rooftop Installation Area” on Exhibit 2 attached hereto (the “Rooftop Installation Area”) solely to operate, maintain, repair and replace rooftop antennas, mechanical equipment, communications antennas and other equipment installed by Tenant in the Rooftop Installation Area in accordance with this Article (“Tenant’s Rooftop Equipment”).  Tenant’s Rooftop Equipment shall be only for Tenant’s use of the Premises for the Permitted Use.

Tenant shall install Tenant’s Rooftop Equipment at its sole cost and expense, at such times and in such manner as Landlord may reasonably designate, and in accordance with this Article and the applicable provisions of this Lease regarding Alterations.  Tenant’s Rooftop Equipment and the installation thereof shall be subject to Landlord’s prior written approval, which approval shall not be unreasonably withheld.  Among other reasons, Landlord may withhold approval if the installation or operation of Tenant’s Rooftop Equipment could reasonably be expected to damage the structural integrity of the Building or to transmit vibrations or noise or cause other adverse effects beyond the Premises to an extent not customary in first class combination office and laboratory buildings, unless Tenant implements measures that are acceptable to Landlord in its reasonable discretion to avoid any such damage or transmission.

Tenant shall comply with any roof or roof-related warranties.  Tenant shall obtain a letter from ▇▇▇▇▇▇▇▇’s roofing contractor within thirty (30) days after completion of any Tenant work on the rooftop stating that such work did not affect any such warranties.  Tenant, at its sole cost and expense, shall inspect the Rooftop Installation Area at least annually, and correct any loose bolts, fittings or other appurtenances and repair any damage to the roof arising from the installation or operation of Tenant’s Rooftop Equipment.  Tenant shall not permit the installation, maintenance or operation of Tenant’s Rooftop Equipment to violate any Legal Requirements, including any applicable noise ordinance of the City of Cambridge, or constitute a nuisance.  Tenant shall pay Landlord within thirty (30) days after demand (a) all applicable taxes, charges, fees or impositions imposed on Landlord by governmental authorities as the result of Tenant’s use of the Rooftop Installation Areas in excess of those for which Landlord would otherwise be responsible for the use or installation of Tenant’s Rooftop Equipment and (b) the amount of any increase in Landlord’s insurance premiums as a result of the installation of Tenant’s Rooftop Equipment.  

If Tenant’s Equipment (a) causes physical damage to the structural integrity of the Building, or (b) interferes with any telecommunications, mechanical or other systems located at or near or servicing the Building that were installed prior to the installation of Tenant’s Rooftop Equipment, then Tenant shall cooperate with Landlord to determine the source of the damage or interference and promptly repair such damage and eliminate such interference, in each case at Tenant’s sole cost and expense, within ten (10) days after receipt of notice of such damage or interference (which notice may be oral; provided that Landlord also delivers to Tenant written notice of such damage or interference within twenty-four (24) hours after providing oral notice).

Landlord reserves the right to cause Tenant to relocate Tenant’s Rooftop Equipment to comparably functional space on the roof or in the penthouse of the Building by giving Tenant prior written notice thereof.  ▇▇▇▇▇▇▇▇ agrees to pay the reasonable costs thereof.  Tenant shall arrange for the relocation of Tenant’s Rooftop Equipment within sixty (60) days after receipt of Landlord’s notification of such relocation.  In the event Tenant fails to arrange for relocation within such sixty (60)-day period, Landlord shall have the right to arrange for the relocation of Tenant’s Rooftop Equipment in a manner that does not unnecessarily interrupt or interfere with ▇▇▇▇▇▇’s use of the Premises for the Permitted Use. Notwithstanding the foregoing, in no event shall Landlord have the right to require Tenant’s Rooftop Equipment to be relocated more than three (3) times during the Term, excluding relocations required in connection with any exercise of Landlord’s recapture right pursuant to Section 13.2 hereof.

As part of the Landlord’s Base Building Work, Landlord shall install a roof deck in the location identified as the “Roof Deck Area” on Exhibit 2 attached hereto.  Any such roof deck shall be for Tenant’s exclusive use, unless pursuant to Section 13.2 Landlord exercises its recapture right with respect to any portion of the second (2^nd) floor of the Premises in which case, if elected by Landlord such roof deck shall be a Common Area.  

1.5Tenant’s Access.

From and after the Commencement Date and until the end of the Term, Tenant shall have access to the Premises (and Permitted Pass Holders shall have access to the Parking Area) twenty-four (24) hours a day, seven (7) days a week, subject to Legal Requirements, the Rules and Regulations, the terms of this Lease, Landlord’s Force Majeure (hereinafter defined) and matters of record.  As used in this Lease, the term “Landlord’s Force Majeure” shall mean delays due to riots, acts of God, war, acts of terrorism, governmental regulation, an emergency where imminent harm to persons or property is at risk, unusual scarcity of or inability to obtain labor or materials, labor difficulties, casualty or any other causes reasonably beyond Landlord’s control.

Subject to Section 11 below, from and after the date that Landlord reasonably believes to be two (2) months prior to the Commencement Date (the “Early Access Period”), to be determined by Landlord, acting in good faith, and in its sole and absolute discretion, Tenant shall have the right to access the Premises, at Tenant’s sole risk, at times reasonably approved by Landlord, for the performance and completion of the Tenant Improvements.  All such work shall be at Tenant’s sole cost and expense, subject to Landlord’s obligations with respect to the Tenant Improvement Allowance, and shall be coordinated with Landlord so that any such work does not unreasonably interfere with ▇▇▇▇▇▇▇▇’s construction of the Landlord’s Base Building Work (as hereinafter defined).  During any such period of early access by Tenant, the construction of Landlord’s Base Building Work shall at all times take priority over the Tenant Improvements.  If Landlord determines that such early access by Tenant or the performance of the Tenant Improvements during the Early Access Period has interfered with the Substantial Completion (as hereinafter defined) of Landlord’s Base Building Work and Tenant has failed to correct such interference within two (2) business days following ▇▇▇▇▇▇’s receipt of notice thereof from Landlord or other Landlord Parties (as hereinafter defined), then the Commencement Date shall be the date that Landlord would have Substantially Completed Landlord’s Base Building Work, as determined by Landlord, but for such interference by ▇▇▇▇▇▇.  Tenant shall, prior to the first entry to the Premises pursuant to this Section 1.5(b), provide Landlord with certificates of insurance evidencing that the insurance required in Section 14 hereof is in full force and effect and covering any person or entity entering the Building.  Tenant shall defend, indemnify and hold the Landlord Parties (hereinafter defined) harmless from and against any and all Claims (hereinafter defined) for injury to persons or property resulting from or relating to Tenant’s access to and use of the Premises prior to the Commencement Date as provided under this Section 1.5(b).  Tenant shall coordinate any access described in this Section 1.5(b) with ▇▇▇▇▇▇▇▇’s property manager and ▇▇▇▇▇▇▇▇’s contractor.  Notwithstanding anything herein to the contrary, Landlord shall not have any liability to Tenant if the Commencement Date occurs earlier than two (2) months after the date Landlord determines is the first day of the Early Access Period.   

5

---

 

In addition to providing Tenant access during the Early Access Period, Landlord, from time to time prior to the Early Access Period, may notify Tenant in writing that Tenant may perform a defined limited scope of the Tenant Improvements, as determined by Landlord (the “Limited Scope TI Work”), if Landlord reasonably believes, in consultation with ▇▇▇▇▇▇▇▇’s contractor and project manager, that it would be beneficial for the efficient construction of the Landlord’s Base Building Work and Tenant Improvements for Tenant to perform such Limited Scope TI Work and that the then-performance of the Limited Scope TI Work will not interfere with the Landlord’s Base Building Work.  The Limited Scope TI Work shall be subject to, and shall be performed in accordance with, the terms and provisions of the immediately foregoing paragraph of this Section 1.5.

1.6Exclusions

The following are expressly excluded from the Premises and reserved to Landlord:  all the perimeter walls of the Premises (except the inner surfaces thereof), the Common Areas, and any space in or adjacent to the Premises used for shafts, stacks, pipes, conduits, wires and appurtenant fixtures, fan rooms, ducts, electric or other utilities, sinks or other Building facilities, and the use of all of the foregoing, except as expressly permitted pursuant to Section 1.4(a) above.

the Condo Documents comply with the provisions of this Section 2.2; (iii) Landlord shall have the right to enter into, and subject the Property to the terms and conditions of, a reciprocal easement agreement with any one or more of the neighboring property owners (including any owner of any portion of the Property that may be divided from the whole) (“REA”); provided that such REA continues to provide Tenant with all of the rights and obligations contained in this Lease with respect to the Building as of the Execution Date (e.g. the appurtenant right to use all Common Areas in the Building) and the REA complies with the provisions of this Section 2.2; (iv) Landlord shall submit to Tenant for Tenant’s review drafts of the Condo Documents and the REA (and any amendments thereto) prior to their execution; (v) Tenant shall have the right to notify Landlord within twenty (20) days after receipt of the draft Condo Documents and/or REA (or any amendments thereto) of Tenant’s objection(s) thereto, but only to the extent such draft(s) (A) materially adversely affect Tenant’s use of, or access to, the Premises, (B) materially adversely affect the operation of Tenant’s business from the Premises in accordance with the terms of this Lease, or Tenant’s rights under and pursuant to the terms of this Lease, including without limitation Tenant’s rights with respect to the Common Areas in the Building, and/or (C) result in any material increase in Tenant’s payment or other obligations under this Lease; (vi) upon Landlord’s request in connection with the recording of the REA, Tenant shall execute a commercially reasonable instrument in recordable form making this Lease subject and subordinate to the REA; (vii) Landlord shall have the right to subdivide the Property so long as Tenant continues to have all of the rights and obligations contained in this Lease with respect to the Building; and (vii) Tenant shall execute such reasonable documents (which may be in recordable form) evidencing the foregoing promptly upon ▇▇▇▇▇▇▇▇’s request.  

2.3Name and Address of Building

Landlord may at any time after it has exercised its recapture right with respect to any portion of the Premises pursuant to Section 13.2 and from time to time thereafter change the name or address of the Building and/or the Property, provided Landlord gives Tenant at least three (3) months’ prior written notice thereof.  If Landlord has not exercised its recapture right with respect to any portion of the Premises pursuant to Section 13.2, Landlord must obtain Tenant’s prior written consent to any such name or address change, not to be unreasonably withheld, conditioned or delayed.  Notwithstanding the foregoing, in the event any such name or address change is required pursuant to any governmental authority or Legal Requirement, Landlord may comply with such requirement without first notifying Tenant or obtaining Tenant’s consent.

2.4Landlord’s Access

Subject to the terms hereof, Tenant shall (a) upon reasonable advance notice (no less than twenty-four (24) hours, or such lesser amount of time as may be agreed upon by Landlord and Tenant), which may be oral or given via email (except that no notice shall be required in emergency situations), permit Landlord and any holder of a Mortgage (hereinafter defined) (each such holder, a “Mortgagee”), and their respective agents, representatives, employees and contractors, to have access to the Premises at all reasonable hours for the purposes of inspection, making repairs, replacements or improvements in or to the Premises or the Building or equipment therein (including, without limitation, sanitary, electrical, heating, air conditioning or other systems), complying with all applicable laws, ordinances, rules, regulations, statutes, by-laws, court decisions and orders and requirements of all public authorities (collectively, “Legal Requirements”), or exercising any right reserved to Landlord under this Lease (including without limitation the right to take upon or through, or to keep and store within the Premises all necessary materials, tools and equipment); (b) permit Landlord and its agents and employees, at reasonable times, upon reasonable advance notice (no less than twenty-four (24) hours, or such lesser amount of time as may be agreed upon by Landlord and Tenant), to show the Premises during normal business hours (i.e., Monday - Friday 8:00 AM – 6:00 PM, Saturday 9:00 AM – 1:00 PM, excluding holidays) (“Business Hours”) to any prospective Mortgagee or purchaser of the Building and/or the

7

---

 

Property or of the interest of Landlord therein, and, during the last twelve (12) months of the Term, or at any time after the occurrence of an Event of Default, prospective tenants; (c) upon reasonable prior written notice from Landlord (no less than forty-eight (48) hours, or such lesser amount of time as may be agreed upon by Landlord and Tenant), permit Landlord and its agents, at ▇▇▇▇▇▇▇▇’s sole cost and expense, to perform environmental audits, environmental site investigations and environmental site assessments (“Site Assessments”) in, on, under and at the Premises and the Land, it being understood that Landlord shall repair any damage arising as a result of the Site Assessments, and such Site Assessments may include both above and below the ground testing and such other tests as may be necessary or appropriate to conduct the Site Assessments; and (d) in case any excavation shall be made for building or improvements or for any other purpose upon the land adjacent to or near the Premises, afford without charge to Landlord, or the person or persons, firms or entities causing or making such excavation, license to enter upon the Premises for the purpose of doing such work as Landlord or such person or persons, firms or entities shall deem to be necessary to preserve the Building from injury, and to protect the Building by proper securing of foundations.  In addition, to the extent that it is necessary to enter the Premises in order to access any area that serves any portion of the Building outside the Premises, then Tenant shall, upon as much advance notice as is practical under the circumstances, and in any event at least twenty-four (24) hours’ prior written notice (except that no notice shall be required in emergency situations), permit contractors engaged by other occupants of the Building to pass through the Premises in order to access such areas but only if accompanied by a representative of Landlord.  The parties agree and acknowledge that, despite reasonable and customary precautions (which Landlord agrees it shall exercise), any property or equipment in the Premises may nevertheless be damaged in the course of performing Landlord’s obligations.  Accordingly, Tenant shall take reasonable protective precautions with its property and equipment, including any property or equipment that is fragile, vulnerable or sensitive.  Notwithstanding anything to the contrary in this Lease, Landlord acknowledges that Tenant will be performing laboratory work of a highly sensitive/fragile nature in certain portions of the Premises which shall be identified in writing to Landlord and shall be subject to Landlord’s reasonable approval (the “Tenant Sensitive Areas”). Accordingly, ▇▇▇▇▇▇▇▇ agrees that any such entry by Landlord onto the Tenant Sensitive Areas shall be in conformance with Tenant’s reasonable security, safety and scientific procedures and protocols and Landlord shall reasonably cooperate with Tenant with respect to such reasonable security, safety and scientific procedures and protocols that Tenant may impose from time to time. In furtherance of the foregoing, Landlord hereby acknowledges and agrees that, at a minimum, ▇▇▇▇▇▇▇▇’s entry onto Tenant Sensitive Areas may be restricted as follows (provided such restrictions do no prohibit Landlord’s reasonable entry onto the Premises (including the Tenant Sensitive Areas) in cases of emergency or threats to the health and safety of occupants of the Building): (i) Landlord shall notify Tenant of ▇▇▇▇▇▇▇▇’s desire to enter Tenant Sensitive Areas and Tenant shall make access to Tenant Sensitive Areas available to Landlord within twenty-four (24) hours and (ii) Landlord’s entry onto Tenant Sensitive Areas may require escort by ▇▇▇▇▇▇’s authorized personnel.

2.5Pipes, Ducts and Conduits

In connection with Landlord’s maintenance and repair obligations under this Lease or in the event Landlord has exercised its recapture right with respect to any portion of the Premises pursuant to Section 13.2, Tenant shall permit Landlord to erect, use, maintain and relocate pipes, ducts and conduits in and through the Premises, provided the same do not materially reduce the floor area or materially adversely affect the appearance thereof.

2.6Minimize Interference

Except in the event of an emergency, Landlord shall use commercially reasonable efforts, consistent with accepted construction practice when applicable, to minimize any materially adverse interference with ▇▇▇▇▇▇’s use and occupancy of the Premises as a result of the exercise of Landlord’s rights under this Article 2.  ▇▇▇▇▇▇ agrees to cooperate with ▇▇▇▇▇▇▇▇ as reasonably necessary in connection with the exercise of ▇▇▇▇▇▇▇▇’s rights under this Article 2.  Subject to Landlord’s obligations under this Section 2.6, ▇▇▇▇▇▇ further agrees that dust, noise, vibration, temporary closures of the Common Areas or Parking Area, or other inconvenience or annoyance resulting from the exercise of ▇▇▇▇▇▇▇▇’s rights under this Article 2 shall not be deemed to be a breach of Landlord’s obligations under the Lease.  Notwithstanding the foregoing, in no event shall any space within the Premises under this Lease be deprived of safe and reasonable access or rendered untenable for the Permitted Uses by reason of Landlord’s exercise of its rights under this Article 2, but excluding the exercise of any rights of Landlord under Section 2.1.

2.7Construction in Vicinity

Tenant acknowledges that (a) Landlord and/or its affiliates (“Neighboring Owners”) own several properties in the vicinity of the Building, (b) during the Term, the Neighboring Owners may undertake various construction projects, which may include the construction of new and/or additional buildings (each, a “Project,” and collectively, the “Projects”), and (c) customary construction impacts (taking into account the urban nature of the Property, the proximity of the Building to the Project site and other relevant factors) may result therefrom.  Landlord shall use commercially reasonable efforts to minimize (and cause its affiliates to minimize) materially adverse construction impacts in accordance with the mitigation plan described below.  Prior to commencing any Project, Landlord shall deliver to Tenant a construction mitigation plan that shall detail such commercially reasonable mitigation measures.  Subject to Landlord’s compliance with this paragraph, and notwithstanding any other provision of this Lease, in no event shall Landlord be liable to Tenant for any compensation or reduction of rent or any other damages arising from the Projects and Tenant shall not have the right to terminate the Lease due to the construction of the Projects, nor shall the same give rise to a claim in Tenant’s favor that such construction constitutes actual or constructive, total or partial, eviction from the Premises.  Notwithstanding any provision in this Lease to the contrary, in no event shall Tenant seek injunctive or any similar relief to stop, delay or modify any Project.   

3.CONDITION OF PREMISES; CONSTRUCTION.

3.1Landlord’s Base Building Work

Landlord, at its sole cost and expense, intends to make certain base Building improvements (“Landlord’s Base Building Work”), as more particularly described on the schedule of drawings attached hereto as Exhibit 6 (the “Landlord’s Base Building Work Drawings”), as well as improvements to the exterior landscaping at the Property.  ▇▇▇▇▇▇ acknowledges and agrees that it has received, reviewed and approves the drawings described on Exhibit 6.  On the Commencement Date, Landlord shall deliver the Premises to Tenant with Landlord’s Base Building Work Substantially Completed (defined below) in a good and workmanlike manner and, except as otherwise provided herein, in compliance with all Legal Requirements, with all base Building systems (including without limitation HVAC, electrical, life-safety and plumbing systems) serving the Premises in good working order and condition in accordance with the Landlord’s Base Building Work Drawings, except for items which because of the seasonal nature of the item (such as HVAC balancing) or which, in accordance with good construction practice, are not practicable to complete at such time.  If Tenant notifies Landlord in writing prior to the date that is three (3) business days after Landlord notifies Tenant that Shell Oil Company has

---

 

vacated the Premises, and in such notice identifies with reasonably specificity the telecommunications cabling that Tenant desires to be removed from the Premises, Landlord shall, as part of Landlord’s Base Building Work, remove from the Premises such telecommunications cabling that is not then in use and timely identified by ▇▇▇▇▇▇.  Landlord’s Base Building Work shall be deemed “Substantially Completed” or “Substantially Complete” when Landlord has obtained a certificate of substantial completion signed by ▇▇▇▇▇▇▇▇’s architect, which may be in the form of the American Institute of Architects document G704, subject to punch list items. Landlord currently estimates Landlord’s Base Building Work will be Substantially Completed on or about October 1, 2020 (the “Estimated Commencement Date”).  Landlord shall use commercially reasonable efforts to tender possession of the Premises to Tenant on the Estimated Commencement Date, with Landlord’s Base Building Work Substantially Complete.  Tenant agrees that in the event such work is not Substantially Complete on or before the Estimated Commencement Date for any reason, then (a) this Lease shall not be void or voidable, (b) Landlord shall not be liable to Tenant for any loss or damage resulting therefrom, and (c) the Expiration Date shall be extended accordingly, provided however, (i) in the event Landlord fails to tender possession of the Premises to Tenant with Landlord’s Base Building Work Substantially Complete within sixty (60) days following the Estimated Commencement Date (the “First Late Commencement Date Deadline”) and such failure is not otherwise caused by Tenant, the six (6) month period between the Commencement Date and the Rent Commencement Date as set forth in the Lease Summary Sheet above shall be extended one (1) day for each day that occurs between the First Late Commencement Date Deadline and the date Landlord actually tenders possession of the Premises to Tenant with Landlord’s Base Building Work Substantially Complete, and (ii) in the event Landlord fails to tender possession of the Premises to Tenant with Landlord’s Base Building Work Substantially Complete within one hundred twenty (120) days following the Estimated Commencement Date (the “Second Late Commencement Date Deadline”) and such failure is not otherwise caused by Tenant, the six (6) month period between the Commencement Date and the Rent Commencement Date as set forth in the Lease Summary Sheet above shall be extended two (2) days for each day that occurs between the Second Late Commencement Date Deadline and the date Landlord actually tenders possession of the Premises to Tenant with Landlord’s Base Building Work Substantially Complete.  Landlord shall keep Tenant informed on a regular basis as to the progress of Landlord’s Base Building Work and any other activities or conditions necessary for Landlord to deliver possession of the Premises to Tenant.  Subject to the foregoing and, except as specifically provided herein, Tenant acknowledges and agrees that ▇▇▇▇▇▇ is leasing the Premises in their “AS IS,” “WHERE IS” condition and with all faults on the Commencement Date, without representations or warranties, express or implied, in fact or by law, of any kind, and without recourse to Landlord.

3.2Tenant Improvements

Tenant shall cause the Tenant Improvements to be constructed in the Premises pursuant to the Work Letter attached hereto as Exhibit 3 (the “Work Letter”) at a cost to Landlord not to exceed Four Million Four Hundred Twenty Six Thousand Five Hundred and 00/100 Dollars ($4,426,500.00) (based upon One Hundred Thirteen and 50/100 Dollars ($113.50) per square foot of rentable area (the “TI Allowance”).  The TI Allowance may be applied to the costs of (m) construction, (n) intentionally omitted, (o) commissioning of mechanical, electrical and plumbing systems by a licensed, qualified commissioning agent hired by ▇▇▇▇▇▇, excluding any commissioning of base Building HVAC equipment, (p) building permits and other taxes, fees, charges and levies by Governmental Authorities (as defined below) for permits or for inspections of the Tenant Improvements, and (q) costs and expenses for labor, material, equipment and fixtures.  In no event shall the TI Allowance be used for (v) the cost of work that is not authorized by the Approved Plans (as defined in the Work Letter) or otherwise approved in writing by Landlord, (w) payments to Tenant or any affiliates of Tenant, (x) the purchase of any furniture, personal property or other non-building system equipment, (y) costs arising from any default by Tenant of its obligations under this Lease or (z) costs that are recoverable by Tenant from a third party (e.g., insurers, warrantors, or tortfeasors). In addition, Landlord shall provide an allowance to Tenant to be used

solely for architectural and engineering costs related to the preparation of an initial test fit plan for the Tenant Improvements in an amount not to exceed Three Thousand Nine Hundred and 00/100 Dollars ($3,900.00) (based upon Ten Cents ($0.10) per square foot of rentable area) (the “Test Fit Plan Allowance”).  Notwithstanding the foregoing, Landlord hereby acknowledges and agrees that any costs incurred by Landlord with respect to project review by Landlord (including without limitation, ▇▇▇▇▇▇▇▇’s actual out of pocket costs incurred by Landlord in reviewing and managing the Tenant Improvements) shall be at Landlord’s sole cost and expense and no portion of the TI Allowance shall be used therefor.  For purposes of clarity, nothing in this Section 3.2 shall limit the costs and expenses incurred by Landlord for which Landlord is entitled to reimbursement by Tenant for Alterations that are not the Tenant Improvements in accordance with Article 11 of this Lease.

 

Tenant shall have until the date that is twelve (12) months after the Rent Commencement Date (the “TI Deadline”), to submit Fund Requests (as defined in the Work Letter) to Landlord for disbursement of the unused portion of the TI Allowance and Test Fit Plan Allowance, after which date Landlord’s obligation to fund any such costs for which Tenant has not submitted a Fund Request to Landlord shall expire.  

 

In no event shall any unused TI Allowance entitle Tenant to a credit against Rent payable under this Lease.  Upon completion of the Tenant Improvements, and prior to any occupancy of the Premises by ▇▇▇▇▇▇, Tenant shall deliver to Landlord (a) a certificate of occupancy (or its substantial equivalent) for the Premises suitable for the Permitted Use and (b) a Certificate of Substantial Completion in the form of the American Institute of Architects document G704, executed by the project architect and the general contractor.

Landlord agrees that Landlord’s Base Building Work shall be constructed in conformance with the ADA.  In the event Landlord’s Base Building Work is not constructed in conformance with the ADA in effect as of the date Landlord commences the Landlord’s Base Building Work, and provided Tenant provides Landlord written notice thereof within three (3) months after the Commencement Date, and provided Landlord does not dispute Tenant’s determination of non-compliance, Landlord shall, as Tenant’s sole and exclusive remedy, address any such non-compliance of Landlord’s Base Building Work (and expressly not any Tenant Improvements or any modifications or alterations of Landlord’s Base Building Work that are made necessary as a result of Tenant Improvements, which such modifications or alterations are Tenant’s sole responsibility and cost).

(b)With respect to the use and occupancy of the Premises and the Common Areas, Tenant will not:  (i) place or maintain any signage (except as may be permitted by Section 12 below), Trash (hereinafter defined) or other articles in any vestibule or entry of the Premises, on the footwalks or corridors adjacent thereto or elsewhere on the exterior of the Premises, nor obstruct any driveway, corridor, footwalk, Parking Area, or any Common Areas; (ii) permit undue accumulations of or burn garbage, trash, rubbish or other refuse (collectively, “Trash”) within or without the Premises; (iii) permit the parking of vehicles so as to interfere with the use of any driveway, corridor, footwalk, or parking area; (iv) receive or ship articles of any kind outside of those areas reasonably designated by Landlord; (v) conduct or permit to be conducted any auction, going out of business sale, bankruptcy sale (unless directed by court order), or other similar type sale in or connected with the Premises; (vi) use the name of Landlord, or any of Landlord’s affiliates or subsidiaries in any publicity, promotion, trailer, press release, advertising, printed, or display materials without Landlord’s prior written consent  (which may be withheld in Landlord’s sole discretion); (vii) except in connection with any vivarium, permit any animals other than service animals in the Building; or (viii) except in connection with Alterations (hereinafter defined) approved by Landlord, cause or permit any hole to be drilled or made in any part of the Building

5.RENT; ADDITIONAL RENT

5.1Base Rent

From and after the Rent Commencement Date, Tenant shall pay to Landlord Base Rent in equal monthly installments, in advance and without demand on the first day of each month for and with respect to such month (except that, if the Rent Commencement Date is any day other than the first day of a calendar month, Base Rent due for the period between the Rent Commencement Date and the last day of the calendar month in which the Rent Commencement Date occurs shall be due on the Rent Commencement Date).  Unless otherwise expressly provided herein, the payment of Base Rent and additional rent and other charges reserved and covenanted to be paid under this Lease with respect to the Premises (collectively, “Rent”) shall commence on the Rent Commencement Date and shall be prorated for any partial months.  Rent shall be payable to Landlord or, if Landlord shall so direct in writing, to Landlord’s agent or nominee, in lawful money of the United States which shall be legal tender for payment of all debts and dues, public and private, at the time of payment.

5.2Operating Costs

(a)Payment of Operating Costs.  From and after the Rent Commencement Date, Tenant shall pay to Landlord, as additional rent, one hundred percent (100%) of all Operating Costs (as defined in Exhibit 7 attached hereto).  Landlord may make a good faith estimate of the Operating Costs for any fiscal year (wholly or partially) occurring during the Term, and Tenant shall pay to Landlord, on the first (1st) day of each calendar month, an amount equal to the estimated Operating Costs for such fiscal year and/or part thereof divided by the number of months therein.  Landlord may estimate and re-estimate the Operating Costs and deliver a copy of the estimate or re-estimate to Tenant.  Thereafter, the monthly installments of Operating Costs shall be appropriately adjusted in accordance with the estimations so that, by the end of the fiscal year in question, Tenant shall have paid all of the Operating Costs as estimated by ▇▇▇▇▇▇▇▇.  Any amounts paid based on such an estimate shall be subject to adjustment as herein provided when the actual Operating Costs are available for each fiscal year.  Notwithstanding anything in this Article 5 to the contrary, Tenant shall pay to Landlord, or directly to the utility provider, all utility costs for the Premises from and after the Commencement Date.

(b)Annual Reconciliation.  Landlord shall, within one hundred twenty (120) days after the end of each fiscal year, deliver to Tenant a reasonably detailed statement of the actual amount of Operating Costs for such fiscal year (“Year End Statement”).  Failure of Landlord to provide the Year End Statement within the time prescribed shall not relieve Tenant from its obligations hereunder.  If the total of such monthly remittances on account of any fiscal year is greater than the Operating Costs actually incurred for such fiscal year, then, provided there is no Event of Default nor any event which, with the passage of time and/or the giving of notice would constitute an Event of Default, Tenant may credit the difference against the next installment of additional rent on account of Operating Costs due hereunder, except that if such difference is determined after the end of the Term, Landlord shall refund such difference to Tenant within thirty (30) days after such determination to the extent that such difference exceeds any amounts then due from Tenant to Landlord (it being understood and agreed that if Tenant cures any default prior to the expiration of the notice and/or cure periods set forth in Section 20.1 below, Tenant shall then be entitled to take such credit).  If the total of such remittances is less than the Operating Costs actually incurred for such fiscal year, Tenant shall pay the difference to Landlord, as additional rent hereunder, within thirty (30) days of Tenant’s receipt of an invoice therefor.  ▇▇▇▇▇▇▇▇’s estimate of the Operating Costs for the next fiscal year shall be based upon the Operating Costs actually incurred for the prior fiscal year as reflected in the Year-End Statement plus a reasonable adjustment based upon estimated increases in Operating Costs.  

13

---

 

(c)Part Years.  If the Commencement Date or the Expiration Date occurs in the middle of a fiscal year, Tenant shall be liable for only that portion of the Operating Costs with respect to such fiscal year within the Term.

(d)Audit Right.  Provided there is no Event of Default, Tenant may inspect or audit Landlord’s records related to Operating Costs for any period of time within the previous fiscal year before the audit or inspection. However, no audit or inspection shall extend to periods of time before the Commencement Date. Landlord shall make its books and records relating to Operating Costs for the previous fiscal year available for inspection by Tenant within thirty (30) days after receipt of written notice from Tenant indicating that Tenant desires to exercise its inspection and audit rights under this Section 5.2(d).  If Tenant fails to object to the calculation of Operating Costs on the Year-End Statement within ninety (90) days after receipt of the Year End Statement and/or fails to complete any such audit or inspection within one hundred eighty (180) days after receipt of the Year End Statement, then Tenant shall be deemed to have waived its right to object to the calculation of the Operating Costs for the year in question and the calculation thereof as set forth on such statement shall be final.  Tenant’s audit or inspection shall be conducted only at Landlord’s offices or the offices of Landlord’s property manager during business hours reasonably designated by Landlord.  Tenant shall pay the cost of such audit or inspection.  Tenant may not conduct an inspection or have an audit performed more than once during any fiscal year.  If such inspection or audit reveals that an error was made in the calculation of Operating Costs previously charged to Tenant, then, provided there is no Event of Default, Tenant may credit the difference against the next installment of additional rent on account of Operating Costs due hereunder, except that if such difference is determined after the end of the Term, Landlord shall refund such difference to Tenant within thirty (30) days after such determination to the extent that such difference exceeds any amounts then due from Tenant to Landlord.  If such inspection or audit reveals an underpayment by ▇▇▇▇▇▇, then Tenant shall pay to Landlord, as additional rent hereunder, any underpayment of any such costs, as the case may be, within ten (10) days after receipt of an invoice therefor.  Tenant shall maintain the results of any such audit or inspection confidential and shall not be permitted to use any third party to perform such audit or inspection, other than an independent firm of certified public accountants (A) reasonably acceptable to Landlord, (B) which is not compensated on a contingency fee basis or in any other manner which is dependent upon the results of such audit or inspection, and (C) which executes Landlord standard confidentiality agreement whereby is shall agree to maintain the results of such audit or inspection confidential.  The provisions of this Section 5.2(d) shall survive the expiration or earlier termination of this Lease.

5.3Taxes

(a)Payment of Taxes.  Tenant shall pay to Landlord, as additional rent, one hundred percent (100%) of all Taxes (as defined in Exhibit 8 attached hereto).  Landlord may make a good faith estimate of the Taxes to be due by Tenant for any Tax Period (as defined in Exhibit 8 attached hereto) or part thereof during the Term, and Tenant shall pay to Landlord, on the Commencement Date and on the first (1st) day of each calendar month thereafter, an amount equal to the estimated Taxes for such Tax Period or part thereof divided by the number of months therein. Landlord may estimate and re-estimate the Taxes and deliver a copy of the estimate or re-estimate to Tenant.  Thereafter, the monthly installments of the Taxes shall be appropriately adjusted in accordance with the estimations so that, by the end of the Tax Period in question, Tenant shall have paid all of the Taxes as estimated by ▇▇▇▇▇▇▇▇.  Any amounts paid based on such an estimate shall be subject to adjustment as herein provided when actual Taxes are available for each Tax Period.  If the total of such monthly remittances is greater than the Taxes actually due for such Tax Period, then, provided no Event of Default has occurred nor any event which, with the passage of time and/or the giving of notice would constitute an Event of Default, Tenant may credit the difference against the next installment of additional rent on account of Taxes due hereunder, except that if such difference is determined after the end of the Term, Landlord shall refund such

14

---

 

difference to Tenant within thirty (30) days after such determination to the extent that such difference exceeds any amounts then due from Tenant to Landlord (it being understood and agreed that if Tenant cures any default prior to the expiration of the notice and/or cure periods set forth in Section 20.1 below, Tenant shall then be entitled to take such credit).  If the total of such remittances is less than the Taxes actually due for such Tax Period, Tenant shall pay the difference to Landlord, as additional rent hereunder, within thirty (30) days of ▇▇▇▇▇▇’s receipt of an invoice therefor.  ▇▇▇▇▇▇▇▇’s estimate for the next Tax Period shall be based upon the actual Taxes attributable to the Property for the prior Tax Period plus a reasonable adjustment based upon estimated increases in Taxes.  In the event that Payments in Lieu of Taxes (“PILOT”), instead of or in addition to Taxes, are separately assessed to certain portions of the Property including the Premises, Tenant agrees, except as otherwise expressly provided herein to the contrary, to pay to Landlord, as additional rent, the amount of such PILOT attributable to the Premises in the same manner as provided above for the payment of Taxes.

(b)Effect of Abatements.  Appropriate credit against Taxes or PILOT shall be given for any refund obtained by reason of a reduction in any Taxes by the assessors or the administrative, judicial or other governmental agency responsible therefor after deduction of Landlord’s expenditures for reasonable legal fees and for other reasonable expenses incurred in obtaining the Tax or PILOT refund.

(c)Part Years.  If the Commencement Date or the Expiration Date occurs in the middle of a Tax Period, Tenant shall be liable for only that portion of the Taxes, as the case may be, with respect to such Tax Period within the Term.

5.4Late Payments

(a)Any payment of Rent due hereunder not paid when due shall bear interest for each month or fraction thereof from the due date until paid in full at the annual rate of ten percent (10%), or at any applicable lesser maximum legally permissible rate for debts of this nature (the “Default Rate”).  Acceptance of interest or any partial payment shall not constitute a waiver of Tenant’s default with respect to the overdue amount or prevent Landlord from exercising any of the other rights and remedies available to Landlord under this Lease or at law or in equity now or hereafter in effect.  Notwithstanding the foregoing, Tenant shall be entitled to a grace period of five (5) business days after written notice from Landlord with respect to the first late payment in any Rent Year.

(b)For each Tenant payment check to Landlord that is returned by a bank for any reason, Tenant shall pay a returned check charge equal to the amount as shall be customarily charged by ▇▇▇▇▇▇▇▇’s bank at the time.

(c)Money paid by Tenant to Landlord shall be applied to ▇▇▇▇▇▇’s account in the following order: first, to any unpaid additional rent, including without limitation late charges, returned check charges, legal fees and/or court costs chargeable to Tenant hereunder; and then to unpaid Base Rent.

5.5No Offset; Independent Covenants; Waiver

Rent shall be paid without notice or demand, and without setoff, counterclaim, defense, abatement, suspension, deferment, reduction or deduction, except as expressly provided herein.  TENANT WAIVES ALL RIGHTS (I) TO ANY ABATEMENT, SUSPENSION, DEFERMENT, REDUCTION OR DEDUCTION OF OR FROM RENT, AND (II) TO QUIT, TERMINATE OR SURRENDER THIS LEASE OR THE PREMISES OR ANY PART THEREOF, EXCEPT AS EXPRESSLY PROVIDED HEREIN.  TENANT HEREBY ACKNOWLEDGES AND AGREES THAT THE OBLIGATIONS OF TENANT UNDER THIS LEASE SHALL BE SEPARATE AND

5.6Survival

Any obligations under this Article 5 which shall not have been paid at the expiration or earlier termination of the Term shall survive such expiration or earlier termination and shall be paid when and as the amount of same shall be determined and be due.

In no event shall the Letter of Credit be deemed to be a prepayment of Rent nor shall it be considered a measure of liquidated damages.  Unless the Letter of Credit is automatically renewing, at least thirty (30) days prior to the maturity date of the Letter of Credit (or any replacement Letter of Credit), Tenant shall deliver to Landlord a replacement Letter of Credit which shall have a maturity date no earlier than the next anniversary of the Commencement Date or one (1) year from its date of delivery to Landlord, whichever is later.

So long as (i) there have not been two (2) or more Events of Default as of the applicable date of the reduction, (ii) there is no Event of Default with respect to a monetary obligation of Tenant as of the date of the reduction, and (iii) there is no material adverse change in Tenant’s chief financial officer and audited financials, then the face amount of the Letter of Credit may be reduced by Tenant to  (w) $1,592,500.00 at the commencement of the second Rent Year, (x) $1,274,000.00 at the commencement of the third Rent Year, and (y) $955,500.00 at the commencement of the fourth Rent Year.  Landlord shall, at no cost to Landlord, cooperate with Tenant and the issuer of the Letter of Credit in connection with any such reduction of the Letter of Credit, if applicable.

7.2Application of Proceeds of Letter of Credit

Upon any monetary default or non-monetary Event of Default of Tenant under this Lease, or if any proceeding shall be instituted by or against Tenant pursuant to any of the provisions of any Act of Congress or State law relating to bankruptcy, reorganizations, arrangements, compositions or other relief from creditors (and, in the case of any proceeding instituted against it, if Tenant shall fail to have such proceedings dismissed within thirty (30) days) or if Tenant is adjudged bankrupt or insolvent as a result of any such proceeding, or upon the end of the Term if there remains any uncured default of which Tenant shall have received notice, Landlord in its sole discretion may draw down all or a part of the Letter of Credit.  The balance of any Letter of Credit cash proceeds shall be held in accordance with Section 7.5 below.  Should the entire Letter of Credit, or any portion thereof, be drawn down by Landlord, Tenant shall, upon the written demand of Landlord, deliver a replacement Letter of Credit in the amount drawn, and ▇▇▇▇▇▇’s failure to do so within ten (10) days after receipt of such written demand shall constitute an additional Event of Default hereunder without further notice or an opportunity to cure.  The application of all or any part of the cash proceeds of the Letter of Credit to any obligation or default of Tenant under this Lease shall not deprive Landlord of any other rights or remedies Landlord may have nor shall such application by Landlord constitute a waiver by Landlord.

7.3Transfer of Letter of Credit

In the event that Landlord transfers its interest in the Premises, Tenant shall upon notice from and at no cost to Landlord, deliver to Landlord an amendment to the Letter of Credit or a replacement Letter of Credit naming ▇▇▇▇▇▇▇▇’s successor as the beneficiary thereof. If Tenant fails to deliver such amendment or replacement within ten (10) days after written notice from Landlord, Landlord shall have the right to draw down the entire amount of the Letter of Credit and hold the proceeds thereof in accordance with Section 7.5 below.

7.4Credit of Issuer of Letter of Credit

7.5Security Deposit

Landlord shall hold the balance of proceeds remaining after a draw on the Letter of Credit (hereinafter referred to as the “Security Deposit”) as security for Tenant’s performance of all its Lease obligations.  After a monetary default or non-monetary Event of Default of Tenant under this Lease, or upon the end of the Term if there remains any uncured default of which Tenant shall have received notice, Landlord may apply the Security Deposit, or any part thereof, to Landlord’s damages without prejudice to any other Landlord remedy.  Should Landlord apply all or any portion of the Security Deposit, Tenant shall, upon the written demand of Landlord, deliver cash in the amount applied, and ▇▇▇▇▇▇'s failure to do so within twenty (20) days after receipt of such written demand shall constitute an additional Event of Default hereunder without further notice or opportunity to cure.  Additionally, if Landlord applies all or any portion of the Security Deposit as aforesaid, Tenant shall have the right to deliver a replacement Letter of Credit in the form and amount required hereunder, and upon receipt of such replacement Letter of Credit, Landlord shall return the unapplied Security Deposit to Tenant.  ▇▇▇▇▇▇▇▇ has no obligation to pay interest on the Security Deposit and may co-mingle the Security Deposit with Landlord’s funds.  Provided that any uncured Event of Default does not then-exist, if Landlord conveys its interest under this Lease, the Security Deposit, or any part not applied previously, shall be turned over to the grantee in which case Tenant shall look solely to the grantee for the proper application and return of the Security Deposit.

7.6Return of Security Deposit or Letter of Credit

Should Tenant comply with all of such terms, covenants and conditions and promptly pay all sums payable by Tenant to Landlord hereunder, the Security Deposit and/or Letter of Credit or the remaining proceeds therefrom, as applicable, shall be returned to Tenant within sixty (60) days after the end of the Term, less any portion thereof which may have been utilized by Landlord to cure any default or applied to any actual damage suffered by Landlord.

Consistent with the levels provided by first class combination office and laboratory buildings in the East Cambridge area, Landlord shall provide to the Common Areas and the Premises HVAC service as follows: (i) with respect to those portions of the Premises dedicated to laboratory use, heat and air conditioning and general exhaust and ventilation 365 days per year, twenty-four (24) hours per day, seven (7) days per week, and (ii) with respect to those portions of the Premises dedicated to office use, heat and air conditioning during Business Hours.  It is expressly acknowledged and agreed that Tenant shall be solely responsible for (A) cooling any data center, server rooms and any other similar areas located in the Premises beyond the standard level of cooling provided, and (B) specialty exhaust, including without limitation exhaust for H2 rooms, radiation hoods and isotope hoods, vivarium, chemical storage rooms which require Class I, Division II classification, if any, and any other special rooms or special Tenant equipment. All costs incurred by Landlord to provide HVAC service to the Premises shall be reimbursed by Tenant to Landlord as additional rent.  Such costs shall include the cost of all utility services used in the operation of the HVAC system(s) providing HVAC service to the Premises and all costs incurred by Landlord in the operation, maintenance, and repair of such system(s).  In addition, to the extent Tenant requires air conditioning service to the office portion of the Premises outside of Business Hours, Tenant shall pay to Landlord as additional rent, a charge reasonably calculated to represent the additional wear and tear to the base Building HVAC system arising from Tenant’s use thereof outside of Business Hours.  Landlord shall allocate to the Premises a portion of the total amount of such costs incurred with respect to the Building based upon the cubic footage of heated, chilled, and fresh air distributed in the Premises as indicated by the energy management system serving the Building as a percentage of the aggregate cubic footage of heated, chilled, and fresh air distributed in the entire Building for the applicable period.  Tenant shall pay such costs monthly, together with monthly installments of Base Rent, on an estimated basis in amounts from time to time reasonably determined by Landlord.  From time to time, and at least annually, Landlord shall deliver to Tenant a reasonably detailed statement of the actual amount of such costs for the period of time since the prior statement, together with a statement of the amounts paid by ▇▇▇▇▇▇ on an estimated basis toward such costs as aforesaid.  If such statement indicates that the estimated amounts paid by Tenant are less than Tenant’s allocable share of the actual amount of such costs for such period of time, then Tenant shall pay the amount of such shortfall to Landlord within thirty (30) days after delivery of such statement.  If such statement indicates that ▇▇▇▇▇▇’s estimated payments for such period of time exceed the actual amount of such costs for such year, then Landlord shall credit the excess against the next due installment(s) of additional rent payable under this Section 9.4.  Whenever the air conditioning systems are in operation, ▇▇▇▇▇▇ agrees to use reasonable efforts to lower and close the blinds or drapes when necessary because of the sun’s position, and to cooperate fully with Landlord with regard to, and to abide by all the reasonable regulations and requirements which Landlord may prescribe for the proper functioning and protection of the air conditioning systems.

(b)Notwithstanding anything to the contrary in this Lease contained, if the Premises shall lack any service which Landlord is required to provide hereunder, or if Tenant's use and occupancy of the Premises or any part thereof shall be disturbed in violation of Section 23 hereof (thereby rendering the Premises or a portion thereof substantially untenantable) such that, for the duration of the Landlord Service Interruption Cure Period (hereinafter defined), the continued operation in the ordinary course of Tenant’s business in any portion of the Premises is materially and adversely affected, and if Tenant ceases to use the affected portion of the Premises (the “Affected Portion”) during the period of untenantability as the direct result of such lack of service or disturbance, then, provided that Tenant ceases to use the Affected Portion during the entirety of the Landlord Service Interruption Cure Period and that such untenantability and Landlord's inability to cure such condition is not caused by the fault or neglect of any of the Tenant Parties, Base Rent shall thereafter be abated in proportion to such untenantability until the day such condition is completely corrected. For purposes hereof, the “Landlord Service Interruption Cure Period” shall be defined as five (5) consecutive business days after ▇▇▇▇▇▇▇▇’s receipt of written notice from Tenant of the condition causing untenantability in the Affected Portion. The provisions of this Section 9.6(b) shall not apply in the event of untenantability caused by causes beyond Landlord’s control or if Landlord is unable to cure such condition as the result of causes beyond Landlord’s control.  The terms and provisions of this Section 9.6(b) shall be Tenant’s sole and exclusive remedy in the event of any breach by Landlord of Section 9.6.

13.ASSIGNMENT, MORTGAGING AND SUBLETTING

13.1Landlord’s Consent Required

Tenant shall not, without ▇▇▇▇▇▇▇▇’s prior written consent, which consent may be withheld in Landlord’s sole discretion, mortgage or otherwise encumber this Lease or the Premises in whole or in part.  Except as expressly otherwise set forth in Section 13.7 below, Tenant shall not, without Landlord’s prior written consent, assign, sublet, license or transfer this Lease or the Premises in whole or in part whether by changes in the ownership or control of Tenant, or any direct or indirect owner of Tenant, whether at one time or at intervals, by sale or transfer of stock, partnership or beneficial interests, operation of law or otherwise, or permit the occupancy of all or any portion of the Premises by any person or entity other than Tenant’s employees (each of the foregoing, a “Transfer”).  Any purported Transfer made without ▇▇▇▇▇▇▇▇’s consent, if required hereunder, shall be void and confer no rights upon any third person, provided that if there is a Transfer, Landlord may collect rent from the transferee without waiving the prohibition against Transfers, accepting the transferee, or releasing Tenant from full performance under this Lease.  In the event of any Transfer in violation of this Article 13, Landlord shall have the right to terminate this Lease upon thirty (30) days’ written notice to Tenant given within sixty (60) days after receipt of written notice from Tenant to Landlord of any Transfer, or within one (1) year after ▇▇▇▇▇▇▇▇ first learns of the Transfer if no notice is given.

25

---

 

that Tenant desires to make a Transfer with respect to either (i) fifty percent (50%) or more of the Premises or (ii) the entire second (2nd) floor of the Building, as applicable, (b) identifies the affected portion of the Premises (the “Recapture Premises”), or indicates that Tenant proposes to assign its interest in this Lease (for purposes of clarity, a Transfer to an Affiliated Entity or Successor as described in Section 13.7 below or a Transfer with respect to less than fifty percent (50%) of the Premises, provided such Transfer is not with respect to the entire second (2nd) floor of the Building, shall not require a Recapture Notice nor give Landlord any right to recapture the Premises (or any portion thereof)), and (c) offers to Landlord to terminate this Lease with respect to the Recapture Premises. Landlord shall have fifteen (15) business days within which to respond to the Recapture Notice.  In the event Landlord fails to respond to such Recapture Notice within such fifteen (15) business day period, Landlord shall be deemed to have waived its right to recapture the Recapture Premises with respect to such particular Transfer.  However, in the event Landlord elects to accept the offer set forth in the Recapture Notice, Landlord and Tenant shall enter into an amendment of this Lease documenting such recapture within thirty (30) days following Landlord’s exercise of such recapture right, subject to Section 13.2(c) below. For the purposes of this Section 13.2, business days shall exclude those days occurring on or between December 23 and January 1 in any calendar year.

(b)If Tenant does not enter into a Transfer on the terms and conditions contained in the Recapture Notice on or before the date which is one hundred eighty (180) days after the earlier of:
(x) the expiration of the 15-business day period specified in Section 13.2(a) above, or (y) the date that Landlord notifies Tenant that Landlord will not accept Tenant’s offer contained in the Recapture Notice, time being of the essence, then prior to entering into any Transfer after such 180-day period, Tenant must deliver to Landlord a new Recapture Notice in accordance with Section 13.2(a) above.

(c)Notwithstanding anything to the contrary contained herein, if Landlord notifies Tenant that it accepts the offer contained in the Recapture Notice or any subsequent Recapture Notice, Tenant shall have the right, for a period of fifteen (15) days following receipt of such notice from Landlord, time being of the essence, to notify Landlord in writing that it wishes to withdraw such offer and this Lease shall continue unmodified and in full force and effect.

13.3Standard of Consent to Transfer

Subject to Landlord’s rights set forth in Section 13.2 to terminate the Lease or suspend the Term, Landlord agrees that, subject to the provisions of this Article 13, Landlord shall not unreasonably withhold, condition or delay its consent to a Transfer at fair market rent and otherwise on the terms contained in the Recapture Notice.  It shall be reasonable for Landlord to withhold its consent to a Transfer (a) if the proposed assignee or sublessee, as the case may be (a “Transferee”) will not use the Premises for the Permitted Uses, or (b) if, in Landlord’s reasonable opinion: the Transferee (i) does not have a tangible net worth and other financial indicators sufficient to meet the Transferee’s obligations under the Transfer instrument in question; (ii) does not have a business reputation compatible with the operation of a first-class combination laboratory, research, development and office building; and/or (c) intends to use the space subject to the Transfer for a use that violates any exclusive or restrictive use provisions then in effect with respect to any portion of the Property.  

13.4Listing Confers no Rights

The listing of any name other than that of Tenant, whether on the doors of the Premises or on the Building directory, or otherwise, shall not operate to vest in any such other person, firm or corporation any right or interest in this Lease or in the Premises or be deemed to effect or evidence any consent of Landlord, it being expressly understood that any such listing is a privilege extended by Landlord revocable at will by written notice to Tenant.

14.7Tenant’s Acts--Effect on Insurance

Tenant shall not do or permit any Tenant Party to do any act or thing upon the Premises or elsewhere in the Building which will invalidate or be in conflict with any insurance policies or warranties covering the Building and the fixtures and property therein; and shall not do, or permit to be done, any act or thing upon the Premises which shall subject Landlord to any liability or responsibility for injury to any person or persons or to property by reason of any business or operation being carried on upon said Premises or for any other reason.  If by reason of Tenant’s use of the Premises or the failure of Tenant to comply with the provisions of this Lease the insurance rate applicable to any policy of insurance shall at any time thereafter be higher than it otherwise would be, Tenant shall reimburse Landlord upon demand for that part of any insurance premiums which shall have been charged because of such use or failure by Tenant, together with interest at the Default Rate until paid in full, within ten (10) days after receipt of an invoice therefor.

15.CASUALTY; TAKING

15.1Damage

If the Premises are damaged in whole or part because of fire or other insured casualty (“Casualty”), or if the Premises are subject to a taking in connection with the exercise of any power of eminent domain, condemnation, or purchase under threat or in lieu thereof (any of the foregoing, a “Taking”), then unless this Lease is terminated in accordance with Section 15.2 below, Landlord shall restore the Building and/or the Premises to substantially the same condition as existed on the Commencement Date, or in the event of a partial Taking which affects the Building and the Premises, restore the remainder of the Building and the Premises not so Taken to substantially the same condition as is reasonably feasible.  If, in Landlord’s reasonable judgment, any element of the Tenant-Insured Improvements can more effectively be restored as an integral part of Landlord’s restoration of the Building or the Premises, such restoration shall also be made by Landlord, but at Tenant’s sole cost and expense.  Subject to rights of Mortgagees, any act or omission by Tenant and/or Tenant’s agents, servants, employees, contractors, subcontractors, licensees and/or subtenants (collectively with Tenant, the “Tenant Parties”) which causes an actual delay in the performance of Landlord’s restoration, Legal Requirements then in existence and to delays for adjustment of insurance proceeds or Taking awards, as the case may be, and instances of Landlord’s Force Majeure, Landlord shall use commercially reasonable efforts to apply for any required permits within ninety (90) days of such Casualty or partial Taking and substantially complete such restoration within one (1) year after Landlord’s receipt of such required permits therefor.  Upon substantial completion of such restoration by Landlord, Tenant shall use diligent efforts to complete restoration of the Premises to substantially the same condition as existed immediately prior to such Casualty or Taking, as the case may be, as soon as reasonably possible.  ▇▇▇▇▇▇ agrees to cooperate with Landlord in such manner as Landlord may reasonably request to assist Landlord in collecting insurance proceeds due in connection with any Casualty which affects the Premises or the Building.  In no event shall Landlord be required to expend more than the Net (hereinafter defined) insurance proceeds Landlord receives (or amount of insurance proceeds Landlord would have received if Landlord had maintained the insurance required by this Lease) for damage to the Premises and/or the Building or the Net Taking award attributable to the Premises and/or the Building.  “Net” means the insurance proceeds or Taking award actually paid to Landlord (and not paid over to a Mortgagee) less all costs and expenses, including adjusters and attorney’s fees, of obtaining the same.  In the fiscal year in which a Casualty occurs, there shall be included in Operating Costs Landlord’s deductible under its property insurance policy.  Except as Landlord may elect pursuant to this Section 15.1, under no circumstances shall Landlord be required to repair any damage to, or make any repairs to or replacements of, any Tenant-Insured Improvements.  Notwithstanding the foregoing, in the event of a Casualty or Taking, Tenant’s obligation to pay Base Rent and additional rent shall ▇▇▇▇▇ (in proportion to the portion of the Premises affected by such Casualty or Taking) until the Premises are restored, provided however, Tenant shall not be entitled to such abatement of Rent for any period Tenant is entitled to receive business interruption insurance pursuant to Exhibit 12.

15.2Termination Rights

(a)Landlord’s Termination Rights.  Landlord may terminate this Lease upon thirty (30) days’ prior written notice to Tenant if:

(i)any material portion of the Building or any material means of access thereto is taken;

(ii)more than fifty percent (50%) of the Building is damaged by Casualty; or

(iii)if the estimated time to complete restoration exceeds one (1) year from the date on which Landlord receives all required permits for such restoration.

(b)Tenant’s Termination Right.  If Landlord is so required but fails to complete restoration of the Premises within the time frames and subject to the conditions set forth in Section 15.1 above, then Tenant may terminate this Lease upon thirty (30) days’ written notice to Landlord; provided, however, that if Landlord completes such restoration within thirty (30) days after receipt of any such termination notice, such termination notice shall be null and void and this Lease shall continue in full force and effect.  The remedies set forth in this Section 15.2(b) and in Section 15.2(c) below are Tenant’s sole and exclusive rights and remedies based upon Landlord’s failure to complete the restoration of the Premises as set forth herein.

(c)Either Party May Terminate.  In the case of any Casualty or Taking affecting the Premises and occurring during the last twelve (12) months of the Term, then (i) if such Casualty or Taking results in more than fifty percent (50%) of the floor area of the Premises being unsuitable for the Permitted Uses, or (ii) the damage to the Premises costs more than $1,000,000 to restore, then either Landlord or Tenant shall have the option to terminate this Lease upon thirty (30) days’ written notice to the other.  In addition, if any Mortgagee does not release sufficient insurance proceeds to cover the cost of Landlord’s restoration work, Landlord shall notify Tenant thereof.  In such event, unless Landlord or ▇▇▇▇▇▇ agrees in writing to cover the difference, Landlord or Tenant may terminate this Lease by written notice to the other within thirty (30) days after such notice from Landlord.

(d)Automatic Termination.  In the case of a Taking of the entire Premises, then this Lease shall automatically terminate as of the date of possession by the Taking authority.

(e)Tenant shall assign to Landlord all of its right, title and interest in and to the insurance proceeds for the Tenant Improvements, and any other Alterations (a) if the Term shall expire prior to the completion of Tenant’s restoration pursuant to Section 15.1 above, or (ii) if this Lease is terminated pursuant to any provision of this Lease prior to the completion of Tenant’s restoration pursuant to Section 15.1 above, in each case equal to the sum of (A) the unamortized amounts paid pursuant to the Work Letter by Landlord for the Tenant Improvements, and (B) the unamortized costs of any portion of any Alterations that were not designated for removal pursuant to Article 11.

(f)Notwithstanding anything to the contrary contained herein, Tenant may not terminate this Lease pursuant to this Article 15 if the Casualty in question was caused by the negligence or willful misconduct of any of the Tenant Parties.

15.4Disposition of Awards

Except for any separate award for Tenant’s movable trade fixtures, relocation expenses, and unamortized leasehold improvements paid for by Tenant (provided that the same may not reduce Landlord’s award), all Taking awards to Landlord or Tenant shall be Landlord’s property without ▇▇▇▇▇▇’s participation, and Tenant hereby assigns to Landlord ▇▇▇▇▇▇’s interest, if any, in such award.  Tenant may pursue its own claim against the Taking authority.

In all events, Tenant shall comply with all applicable provisions of the BMBL.  Tenant shall be responsible for assuring that all laboratory uses are adequately and properly vented.  Without limiting the foregoing, Tenant shall keep and store at the Premises only such quantities of Tenant’s Hazardous Materials that Tenant reasonably believes to be necessary for the conduct of its ordinary course of business and consistent with prudent industry practice.  On or before each anniversary of the Rent Commencement Date, and at least thirty (30) days prior to any earlier date during the 12-month period on which Tenant intends to add a new Hazardous Material to, or materially increase the quantity of any Hazardous Material already on, the list of Tenant’s Hazardous Materials, Tenant shall submit to Landlord an updated list of Tenant’s Hazardous Materials for Landlord’s review and approval, which approval shall not be unreasonably withheld, conditioned or delayed.  Tenant shall provide such further information concerning any Tenant’s Hazardous Materials and/or their use, storage and/or disposal within thirty (30) days of Landlord’s reasonable request concerning the same.  Landlord shall have the right, from time to time, to inspect the Premises for compliance with the terms of this Section 17.1 at Tenant’s sole cost and expense.  With respect to any Hazardous Material brought or permitted to be brought or kept in or on the Premises or elsewhere in the Building or the Property in accordance with the foregoing, Tenant shall (i) not permit any such Hazardous Material to escape, be released or be disposed in or about the Premises, the Building or the Land and (ii) within five (5) business days of Landlord’s reasonable request, which request shall not be made more frequently than one time per calendar year unless otherwise required by a governmental authority or Landlord reasonably suspects, that a release of a Hazardous Material has occurred upon the Premises, provide evidence reasonably satisfactory to Landlord of Tenant’s compliance with all applicable Environmental Laws including copies of all licenses, permits and registrations that Tenant has been required to obtain prior to handling any Hazardous Material at the Premises and that have not been previously provided to Landlord.  Notwithstanding the foregoing, with respect to any of Tenant’s Hazardous Materials which Tenant does not properly handle, store or dispose of in compliance with all applicable Environmental Laws (hereinafter defined), prudent environmental practice and (with respect to medical waste and so-called “biohazard” materials) good scientific and medical practice, Tenant shall, upon written notice from Landlord, no longer have the right to bring such material into the Building or the Property until Tenant has demonstrated, to Landlord’s reasonable satisfaction, that Tenant has implemented programs to thereafter properly handle, store or dispose of such material.  In order to induce Landlord to waive its otherwise applicable requirement that Tenant maintain insurance in favor of Landlord against liability arising from the presence of radioactive materials in the Premises, and without limiting the foregoing, Tenant hereby represents and warrants to Landlord that at no time during the Term will Tenant bring upon, or permit to be brought upon, the Premises any radioactive materials, other than such radioactive materials allowed by Tenant’s existing permit and such other radioactive materials approved by the Massachusetts Department of Public Health Radiation Control Program of which Landlord has provided its prior written approval, and are used, stored and disposed of in compliance with all Legal Requirements.

Tenant shall, at Tenant’s sole cost and expense, apply for, seek and obtain all necessary state and local licenses, permits and approvals needed for the operation of Tenant’s business (collectively, the “Required Permits”), including the Landlord Required License (as hereinafter defined).  Tenant shall thereafter maintain all Required Permits.  Tenant, at Tenant’s expense, shall at all times comply with the terms and conditions of each such Required Permit.  Tenant’s foregoing obligations include, but are not limited to, obtaining, maintaining and complying with any license required by Legal Requirements for the storage of flammable materials.  Landlord shall reasonably cooperate with Tenant, at Tenant’s sole cost and expense, in connection with its application for Required Permits, which includes a right and obligation on the part of Landlord to attend and participate in public hearings or meetings with Governmental Authorities and/or abutting property owners and community groups, and, if necessary or appropriate, to communicate with public officials, abutters and community groups. Notwithstanding the foregoing, and to the extent any license from the Cambridge License Commission (or the Cambridge Fire Department, as the case may be) for the storage of flammable materials is required by Legal Requirements to be obtained by Landlord (a “Landlord Required License”), and if Landlord does not execute any application for the Landlord Required License that Tenant prepares for Landlord (which Tenant shall be responsible for filing) on the City of Cambridge’s required form and that provides for flammable materials that are the same as the materials specified in Exhibit 13 attached hereto (as revised from time to time pursuant to the terms of this Lease) and that are not in excess of seven hundred ninety three (793) gallons in the aggregate, Landlord agrees that in the event Landlord does not execute such application within thirty (30) days after ▇▇▇▇▇▇▇▇’s receipt of a written completed application from Tenant (or receipt of a written notice from the Cambridge License Commission or any other governmental authority having jurisdiction over the Building, as the case may be), Tenant may apply for, obtain and maintain such Landlord Required License on behalf of Landlord, and Landlord shall be responsible for paying for any application or maintenance fees therefor. In the event Tenant exercises its right to apply for, obtain and/or maintain such Landlord Required License, and, if pursuant to Legal Requirements, Tenant is required to be named as Landlord’s agent and attorney-in-fact in connection with such application or maintenance of such Landlord Required License, then Landlord shall either execute such documentation reasonably requested by Tenant to appoint Tenant to act as Landlord’s agent and attorney-in-fact in connection therewith or, Landlord, in its sole and absolute discretion, may elect to undertake to obtain and maintain the Landlord Required License.  In the event Landlord fails to reasonably cooperate with Tenant or to execute such documentation reasonably requested by ▇▇▇▇▇▇ to appoint Tenant to act as Landlord’s agent and attorney-in-fact, as required by this Section 19.2, to the extent required by Legal Requirements, or, if Landlord opts not to execute such documents, Landlord fails to undertake to obtain the Landlord Required License, within thirty (30) days of Landlord’s receipt of written notice of such failure from Tenant, and as a direct result of such failure Tenant is prevented or prohibited from legally storing and/or using flammable and combustible materials in the Premises, ▇▇▇▇▇▇’s obligation to pay Rent shall ▇▇▇▇▇ for the period commencing on the thirty-first (31^st) day following ▇▇▇▇▇▇▇▇’s receipt of such written notice of ▇▇▇▇▇▇▇▇’s failure and ending on the day that ▇▇▇▇▇▇▇▇ has remedied such failure.  Within ten (10) business days of a request by Landlord, which request shall be made not more than once during each period of twelve (12) calendar months during the Term hereof unless otherwise requested by an Mortgagee or unless Landlord reasonably suspects that ▇▇▇▇▇▇ has violated the provisions of this Section 19.2, Tenant shall furnish Landlord with copies of all Required Permits together with a certificate certifying that such permits are all of the permits that Tenant has obtained with respect to the Premises. If Landlord, in its reasonable discretion, determines that Tenant is not adequately or diligently prosecuting the Landlord Required License, then Landlord, upon prior notice to Tenant, may elect to undertake to obtain and maintain the Landlord Required License at Tenant’s sole cost.

42

---

 

(ii)amounts equal to Rent which would have been payable by Tenant had this Lease not been so terminated, payable upon the due dates therefor specified herein following such termination and until the Expiration Date, provided, however, if Landlord shall re-let the Premises during such period, that Landlord shall credit Tenant with the net rents received by Landlord from such re-letting, such net rents to be determined by first deducting from the gross rents as and when received by Landlord from such re-letting the expenses incurred or paid by Landlord in terminating this Lease, as well as the expenses of re-letting, including altering and preparing the Premises for new tenants, brokers’ commissions, and all other similar and dissimilar expenses properly chargeable against the Premises and the rental therefrom (collectively, “Reletting Costs”), it being understood that any such re-letting may be for a period equal to or shorter or longer than the remaining Term at Landlord’s sole and absolute discretion without otherwise affecting this remedy; and provided, further, that (x) in no event shall Tenant be entitled to receive any excess of such net rents over the sums payable by Tenant to Landlord hereunder and (y) in no event shall Tenant be entitled in any suit for the collection of damages pursuant to this Section 20.3(a)(ii) to a credit in respect of any net rents from a re-letting except to the extent that such net rents are actually received by Landlord prior to the commencement of such suit.  If the Premises or any part thereof should be re-let in combination with other space, then proper apportionment on a square foot area basis shall be made of the rent received from such re-letting and of the expenses of re-letting.

(b)In calculating the amount due under Section 20.3(a)(i), above, there shall be included, in addition to the Base Rent, all other considerations agreed to be paid or performed by ▇▇▇▇▇▇, including without limitation the Operating Costs and Taxes, on the assumption that all such amounts and considerations would have increased at the rate of five percent (5%) per annum for the balance of the full term hereby granted.

(c)Suit or suits for the recovery of such damages, or any installments thereof, may be brought by Landlord from time to time at its election, and nothing contained herein shall be deemed to require Landlord to postpone suit until the date when the Term would have expired if it had not been terminated hereunder.

(d)Nothing herein contained shall be construed as limiting or precluding the recovery by Landlord against Tenant of any sums or damages to which, in addition to the damages particularly provided above, Landlord may lawfully be entitled by reason of any Event of Default hereunder.

(e)In lieu of any other damages or indemnity and in lieu of full recovery by Landlord of all sums payable under all the foregoing provisions of this Section 20.3, Landlord may, by written notice to Tenant, at any time after this Lease is terminated under any of the provisions herein contained or is otherwise terminated for breach of any obligation of Tenant and before such full recovery, elect to recover, and Tenant shall thereupon pay, as liquidated damages, an amount equal to the aggregate of (x) an amount equal to the lesser of (1) Rent accrued under this Lease in the twelve (12) months immediately prior to such termination, or (2) Rent payable during the remaining months of the Term if this Lease had not been terminated, plus (y) the amount of Rent accrued and unpaid at the time of termination, less (z) the amount of any recovery by Landlord under the foregoing provisions of this Section 20.3 up to the time of payment of such liquidated damages; Tenant hereby acknowledging that the damages which Landlord may suffer as the result of the termination of this Lease as a result of an Event of Default over cannot be determined as of the Execution Date.  The terms and provisions of Section 20.3 shall survive the expiration or termination of this Lease.

20.4Landlord’s Self-Help; Fees and Expenses

If a Tenant Event of Default shall occur with respect to the performance of any covenant on Tenant’s part to be performed in this Lease contained, including the obligation to maintain the Premises in the required condition pursuant to Section 10.1 above, or if prior to the expiration of any applicable cure period with respect to any non-monetary default of Tenant, Landlord reasonably determines that any further delay in Tenant’s curing of the performance of any such covenant is likely to cause further damage to the Premises, Landlord may, upon reasonable advance notice, except that no notice shall be required in an emergency, immediately, or at any time thereafter, perform the same for the account of Tenant.  Tenant shall pay to Landlord upon demand therefor any reasonable costs incurred by Landlord in connection therewith, together with interest at the Default Rate until paid in full.  In addition, Tenant shall pay all of Landlord’s reasonable costs and expenses, including without limitation reasonable attorneys’ fees, incurred (i) in enforcing any obligation of Tenant under this Lease or (ii) as a result of Landlord or any of the Landlord Parties being made party to any litigation pending by or against any of the Tenant Parties.

20.5Waiver of Redemption, Statutory Notice and Grace Periods

Tenant does hereby waive and surrender all rights and privileges which it might have under or by reason of any present or future Legal Requirements to redeem the Premises or to have a continuance of this Lease for the Term hereby demised after being dispossessed or ejected therefrom by process of law or under the terms of this Lease or after the termination of this Lease as herein provided.  Except to the extent prohibited by Legal Requirements, any statutory notice and grace periods provided to Tenant by law are hereby expressly waived by Tenant.

20.6Landlord’s Remedies Not Exclusive

The specified remedies to which Landlord may resort hereunder are cumulative and are not intended to be exclusive of any remedies or means of redress to which Landlord may at any time be lawfully entitled, and Landlord may invoke any remedy (including the remedy of specific performance) allowed at law or in equity as if specific remedies were not herein provided for; Tenant hereby acknowledging that the damages which Landlord may suffer as the result of the termination of this Lease as a result of an Event of Default over cannot be determined as of the Execution Date.

20.7No Waiver

▇▇▇▇▇▇▇▇’s failure to seek redress for violation, or to insist upon the strict performance, of any covenant or condition of this Lease, or any of the Rules and Regulations promulgated hereunder, shall not prevent a subsequent act, which would have originally constituted a violation, from having all the force and effect of an original violation.  The receipt by Landlord of Rent with knowledge of the breach of any covenant of this Lease shall not be deemed a waiver of such breach.  The failure of Landlord to enforce any of such Rules and Regulations against Tenant shall not be deemed a waiver of any such Rules and Regulations.  No provisions of this Lease shall be deemed to have been waived by either party unless such waiver be in writing signed by such party against whom a waiver is claimed.  No payment by Tenant or receipt by Landlord of a lesser amount than the Rent herein stipulated shall be deemed to be other than on account of the stipulated Rent, nor shall any endorsement or statement on any check or any letter accompanying any check or payment as Rent be deemed an accord and satisfaction, and Landlord may accept such check or payment without prejudice to Landlord’s right to recover the balance of such Rent or pursue any other remedy in this Lease provided.

44

20.8Restrictions on Tenant’s Rights

During the continuation of any Event of Default, (a) Landlord shall not be obligated to provide Tenant with any notice pursuant to Sections 2.3 and 2.4 above; and (b) Tenant shall not have the right to make, nor to request Landlord’s consent or approval with respect to, any Alterations.

20.9Landlord Default

Notwithstanding anything to the contrary contained in the Lease, Landlord shall in no event be in default in the performance of any of Landlord’s obligations under this Lease unless Landlord shall have failed to perform such obligations within thirty (30) days (or such additional time as is reasonably required to correct any such default, provided Landlord commences cure within 30 days and diligently endeavors to correct such default) after written notice by Tenant to Landlord properly specifying wherein Landlord has failed to perform any such obligation (a “Landlord Default”).  Except as expressly set forth in this Lease, Tenant shall not have the right to terminate or cancel this Lease or to withhold Rent or to set-off or deduct any claim or damages against Rent as a result of any default by Landlord or breach by Landlord of its covenants or any warranties or promises hereunder.  In addition, Tenant shall not assert any right to deduct the cost of repairs or any monetary claim against Landlord from Rent thereafter due and payable under this Lease.  If Landlord commits a Landlord Default which materially affects Tenant’s ability to conduct business in the Premises, Tenant, in addition to any other rights and remedies available under the law, may, without being obligated and without waiving the Landlord Default, cure the Landlord Default (“Tenant Self-Help”), provided however, prior to exercising any Tenant’s Self Help, Tenant shall provide Landlord with written notice thereof, which notice shall be delivered in an envelope that conspicuously states the following in bold caps: “TENANT NOTICE OF INTENTION TO EXERCISE SELF-HELP” and which notice shall include an explicit statement that such notice is a notice delivered pursuant to this Section 20.9 and Landlord's failure to perform the specified obligation will trigger the provisions of this Section 20.9, and shall specifically state that if Landlord fails to commence to cure such Landlord Default within five (5) business days (the “Outside Cure Date”), Tenant intends to exercises Tenant’s Self-Help. If Landlord fails to commence to cure such Landlord Default by the Outside Cure Date, Tenant shall then be entitled to exercise Tenant’s Self-Help. Landlord shall pay Tenant, within thirty (30) days after written demand, all reasonable third-party out of pocket costs, expenses, and disbursements incurred by Tenant in the exercise of Tenant’s Self Help necessary to cure the Landlord Default, including all reasonable legal fees, costs and expenses (including paralegal fees, expert fees, and other professional fees and expenses). It is understood and agreed that ▇▇▇▇▇▇’s exercise of any right or remedy due to a Landlord Default shall not be deemed a waiver of or to alter, affect, or prejudice any right or remedy which Tenant may have under this Lease or by law or in equity. Neither the payment of Rent nor any other acts or omissions of Tenant at any time after a Landlord Default, shall operate as a waiver of any past or future violation, breach, or failure to keep or perform any covenant, agreement, term, or condition hereof.

21.SURRENDER; ABANDONED PROPERTY; HOLD-OVER

If any of the Tenant Parties holds over after the end of the Term, Tenant shall be deemed a tenant-at-sufferance subject to the provisions of this Lease; provided that whether or not Landlord has previously accepted payments of Rent from Tenant, (i) during the first sixty (60) days of any such holdover, Tenant shall pay Base Rent at 150% of the highest rate of Base Rent payable during the Term, (ii) after the first sixty (60) days of any such holdover, Tenant shall pay Base Rent at 200% of the highest rate of Base Rent payable during the Term, (iii) Tenant shall continue to pay to Landlord all additional rent, and (iv) after the first thirty (30) days after any such holdover Tenant shall be liable for all damages, including without limitation lost business and consequential damages, incurred by Landlord as a result of such holding over.

Tenant’s rights and interests under this Lease shall be (i) subject and subordinate to any existing or future (a) ground lease (including without limitation the Master Lease), (b) subleases or other instruments pursuant to any sale and leaseback transaction of the Master Lease or the Property, and (c) any mortgages, deeds of trust, overleases, or similar instruments covering the Premises, the Building and/or the Land and to all advances, modifications, renewals, replacements, and extensions thereof (each of the foregoing, a “Mortgage”), or (ii) if any Mortgagee elects, prior to the lien of any present or future Mortgage.  Tenant further shall attorn to and recognize any successor landlord, whether through foreclosure or otherwise, as if the successor landlord were the originally named landlord.  The provisions of this Section 22.1 shall be self-operative and no further instrument shall be required to effect such subordination or attornment (“SNDA”); however, ▇▇▇▇▇▇ agrees to execute, acknowledge and deliver such instruments, confirming such subordination and attornment in a commercially reasonable form of SNDA within ten (10) days of request therefor.  Landlord hereby agrees to use commercially reasonable efforts to obtain an SNDA from any ground lessor, sublessor, or Mortgagee upon request from Tenant.  With respect to the Master Lease, Tenant and Landlord shall execute and deliver to the other, simultaneously with its execution and delivery of this Lease, the Subordination, Non-Disturbance and Attornment Agreement (the “Master Lease SNDA”), executed by the Master Lessor (as defined in the Master Lease SNDA) in the form attached hereto as Exhibit 15. Landlord may record the Master Lease SNDA in the Registry at its sole cost and expense.  

22.2Mortgagee Notices

Tenant shall give each Mortgagee, at the address provided to Tenant, the same notices given to Landlord concurrently with the notice to Landlord, and each Mortgagee shall have a reasonable opportunity to cure a Landlord default after the expiration of Landlord’s applicable notice and/or cure periods if Landlord fails to do so, and Mortgagee’s curing of any of Landlord’s default shall be treated as performance by Landlord.

Tenant’s fiscal year is January 1 through December 31. Tenant may change its fiscal year upon written notice to Landlord.

25.16Measurements

Within sixty (60) days following the date Landlord’s Base Building Work is Substantially Completed, Landlord, at Landlord’s sole costs and expense, shall cause the Premises to be measured by an architect selected by Landlord in accordance with the then-current Standard Method of Measurement for Combination Laboratory and Office Buildings (ANSI/BOMA) (or if such standard is not in use or no longer in use, using an industry-standard method of measurement reasonably selected by Landlord).  Upon Landlord’s receipt of such measurement (which measurement shall include reasonable details of the methodology used by the architect performing such measurement), Landlord shall provide same to Tenant for review and approval, which approval shall not be unreasonably withheld, conditioned or delayed.  Within ten (10) business days of Tenant’s receipt of such measurement (including applicable details of measurement as required above), Tenant shall notify Landlord of any discrepancy or objection.  After receipt of any such notice of discrepancy or objection, Landlord shall reasonably cooperate with Tenant to resolve any such discrepancies or objections.  Upon final approval of such measurement by both parties, Landlord and Tenant shall make appropriate adjustments to Base Rent, the TI Allowance and any other provisions of this Lease which are based on the rentable square footage of the Premises.  Such adjustments shall be reflected in an agreement prepared by Landlord confirming such measurements and adjustments to be executed by Landlord and Tenant within ten (10) business days after the final determination of such measurement.

retroactively adjust the amounts due to the Commencement Date and parties shall pay or be credited with such payment as applicable.  Tenant shall pay all Rent when due based on the Base Rent and additional rent provided for in this Lease with the Premises consisting of 39,000 rentable square feet until Landlord and Tenant have executed such measurement agreement or Tenant is deemed to have approved such final measurement.  Tenant’s failure to execute and return any such agreement proposed by ▇▇▇▇▇▇▇▇, or to provide written objection to the measurement or the statements and/or methodology contained therein, or a draft of such agreement proposed by ▇▇▇▇▇▇▇▇, within ten (10) business days after the date of Tenant’s receipt thereof, shall be deemed an approval by Tenant of Landlord’s determination of such measurements and adjustments as set forth therein. Additionally, Landlord and Tenant hereby acknowledge Landlord is currently seeking permits and approvals from the City of Cambridge for Landlord’s Base Building Work, and as a result, the Building dimensions and floor area may change to comply with the Legal Requirements or other requirements of city officials.  If any such changes are implemented or required, Landlord shall have the right to modify Exhibit 2 and the demising boundaries of the Premises, and shall substitute a new Exhibit 2 in place of the Exhibit 2 currently attached hereto.  To the extent any such changes modify the rentable square feet of the Premises, Landlord shall make appropriate adjustments to the Base Rent, the TI Allowance and such other provisions of this Lease which are based on the rentable square footage of the Premises.

25.17OFAC

Tenant shall notify Landlord immediately if these circumstances change.  

25.18Confidentiality

▇▇▇▇▇▇ acknowledges and agrees that the terms of this Lease are confidential.  Disclosure of the terms hereof could adversely affect the ability of Landlord or Landlord’s affiliates to negotiate other leases for real property in the Cambridge, Massachusetts area and may impair Landlord’s relationship with other tenants of the Building.  Tenant agrees that it and its partners, officers, directors, employees, brokers, and attorneys, if any, shall not disclose the terms and conditions of this Lease to any other person or entity, including any media (including social media) or news outlets, without the prior written consent of Landlord, which may be given or withheld by Landlord, in Landlord’s sole discretion, except as required for financial disclosures or securities filings, as required by the order of any court or public body with authority over Tenant, or in connection with any litigation between Landlord and Tenant with respect to this Lease.  It is understood and agreed that damages alone would be an inadequate remedy for the breach of this provision by ▇▇▇▇▇▇, and Landlord shall also have the right to seek specific performance of this provision and to seek injunctive relief to prevent its breach or continued breach.

25.19Security

Tenant acknowledges that security devices and services, if any, while intended to deter crime, may not in given instances prevent theft or other criminal acts. Landlord shall not be liable for injuries or losses caused by criminal acts of third parties, and ▇▇▇▇▇▇ assumes the risk that any security device or service may malfunction or otherwise be circumvented by a criminal.

25.22Bankruptcy

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 Legal Requirements, proposes to cure any Tenant default under this Lease or to assume or assign Tenant’s interest under 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: (i) those acts specified in the Bankruptcy Code or other Legal Requirements as included within the meaning of “adequate assurance,” even of this Lease does not concern a shopping center or other facility described in such Legal Requirements; (ii) a prompt cash payment to compensate Landlord for any monetary defaults or actual damages arising directly from a breach of this Lease; (iii) a cash deposit in an amount at least equal to the then-current amount of the Letter of Credit; or (iv) the assumption or assignment of all of Tenant’s interest and obligations under this Lease.
