E.Landlord and Tenant therefore desire to enter into this Sixth Amendment to set forth the terms and conditions for the leasing of the Sixth Amendment Additional Premises, the extension of the Term, and to amend the Lease as hereinafter set forth.
A G R E E M E N T:


NOW, THEREFORE, in consideration of the mutual covenants contained herein and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Landlord and Tenant agree to amend the Lease as follows:
1.Expansion of Premises.
(a)     Effective as of the Sixth Amendment Additional Premises Commencement Date (as hereinafter defined), the Sixth Amendment Additional Premises shall be added to the Existing Premises so that the Premises shall include the Existing Premises and the Sixth Amendment Additional Premises upon all of the terms and conditions of the Lease except as modified herein.  The lease of the Sixth Amendment Additional Premises shall terminate on the Lease Expiration Date (as defined herein), unless extended or sooner terminated as provided in the Lease.  As used herein, the term “Sixth Amendment Additional Premises Commencement Date” shall mean the Effective Date.  As of the Sixth Amendment Additional Premises Commencement Date, the Sixth Amendment Additional Premises have been delivered to Tenant, and Tenant has accepted the Sixth Amendment Additional Premises in their as-is condition. 
(b)    From and after the Sixth Amendment Additional Premises Commencement Date, Building 4 shall be deemed to be a “Building” and one of the “Buildings” as defined in Section 1.1 of the Lease (including, without limitation, for purposes of Section 5.17 of the Lease) and Tenant shall have, as appurtenant to the Premises, the non-exclusive right to use in common with others any Common Areas (as defined in the Lease) located in or necessary for access to Building 4.  
(c)     From and after the Sixth Amendment Additional Premises Commencement Date, the “Rentable Floor Area of the Premises” as used in the Lease shall mean 208,686 square feet, being the sum of (i) the Rentable Floor Area of the Existing Premises containing 203,041 rentable square feet, and (ii) the Rentable Floor Area of the Sixth Amendment Additional Premises containing 5,645 rentable square feet.


2.Fixed Rent and Additional Rent for Early Rent Commencement of Sixth Amendment Additional Premises.  With respect to the Sixth Amendment Additional Premises, Tenant shall pay Fixed Rent and Additional Rent beginning on the date (the “Sixth Amendment Additional Premises Rent Commencement Date”) which is the earlier of (a) the date on which a certificate of occupancy is issued for the Sixth Amendment Additional Premises following substantial completion of the Sixth Amendment Tenant Alterations (defined in Exhibit D hereto) and (b) January 1, 2018.  If the Sixth Amendment Additional Premises Rent Commencement Date occurs prior to January 1, 2018, Rent shall be due for the Sixth Amendment Additional Premises as follows.  Annual Fixed Rent shall be $95,965.00, payable in monthly installments of $7,997.00 per month.  Tenant

EAST\141300457.11 







shall pay Operating Expenses Allocable to the Sixth Amendment Additional Premises and Landlord’s Tax Expenses Allocable to the Sixth Amendment Additional Premises as Additional Rent, in accordance with the terms of the Original Lease without regard to any base year (i.e., net of Tenant’s share of Operating Expense and Taxes).  Annual Fixed Rent and Additional Rent for any partial month for which Rent is due shall be paid at the rates set forth above on a pro rata basis.  
3.Landlord’s Work.  Landlord shall perform the work described in Exhibit C attached hereto (the “Landlord Work Letter”).  Tenant acknowledges that (a) it is fully familiar with the condition of the Premises and agrees to take the same in its condition “as is” as of the First Extension Term Commencement Date (as hereinafter defined) and (b) Landlord shall have no obligation to alter, repair or otherwise prepare the Premises for Tenant’s occupancy or to pay for or construct any improvements to the Premises to prepare the same for Tenant’s occupancy during the First Extension Term, except as set forth in the Landlord Work Letter and subject to Landlord’s express obligations under the Lease.
4.Tenant’s Work.  If Tenant elects to perform the Sixth Amendment Tenant Alterations, such alterations shall be performed in accordance with the terms of Exhibit D.  For ease of reference, Exhibit D includes the definition of “Sixth Amendment Tenant Alterations” and sets forth the “Sixth Amendment Construction Allowance.”
5.First Extension Term.  Notwithstanding anything to the contrary contained in the Lease, the Term of the Lease for the Premises (as the same is expanded by this Sixth Amendment to include the Sixth Amendment Additional Premises) is hereby extended for an additional ten (10) years (the “First Extension Term”) commencing on May 1, 2020 and expiring on April 30, 2030 (the “Lease Expiration Date”), unless extended as provided in Section 7 of this Sixth Amendment or sooner terminated in accordance with the terms of the Lease.  
6.Rent.  
(a)    Annual Fixed Rent.  From and after January 1, 2018, the Annual Fixed Rent for the Premises shall be as follows:

(b)    Additional Rent.  Effective as of January 1, 2018, notwithstanding anything to the contrary contained in the Lease (including Section 3 of the Third Amendment), Tenant shall pay Operating Expenses Allocable to the Premises and Landlord’s Tax Expenses Allocable to the Premises in accordance with the terms of the Original Lease without regard to any base year.
(c)    Annual Fixed Rent and Additional Rent for Existing Premises.  Prior to January 1, 2018, Tenant shall continue to pay Annual Fixed Rent and Additional Rent with respect to the Existing Premises in accordance with the terms of the Lease and without regard to the terms of this Sixth Amendment.
(d)    Electricity.  During the remainder of the Original Term and during the First Extension Term, Tenant shall continue to pay all charges for electricity consumed in the Existing Premises in accordance with the terms of the Lease, as heretofore amended.  Landlord has installed and rendered operational a check meter to measure electricity usage solely in the Sixth Amendment Additional Premises.  Beginning on the Sixth Amendment Additional Premises Commencement Date and continuing through the expiration or earlier termination of the Term (as it may have been extended), Tenant shall pay all charges for electricity consumed in the Sixth Amendment Additional Premises based upon the check meter readings for the Sixth Amendment Additional Premises at the actual rates charged by the utility provider, without any markup by Landlord of such utility rates.  Notwithstanding the foregoing, if any check meter for measuring Tenant’s electricity usage malfunctions or is otherwise not operating properly (other than due to a Landlord default), Landlord may charge Tenant for electricity consumed in the applicable portion of the Premises during the period of malfunction (plus a period of ten (10) days after being made aware of such malfunction) based on reasonable industry-standard methods to reasonably estimate use and Tenant’s past usage.  At Landlord’s option and at Landlord’s sole expense, Landlord may install direct meters for measuring Tenant’s consumption of electricity in any area of the Premises which is not directly metered, and, in such event, Tenant shall thereafter pay all costs and expenses for such separately-


4
EAST\141300457.11 







metered electricity directly to the utility provider.  The costs of electricity supplied to other leasable areas of Building 4 shall be excluded from Landlord’s Operating Expenses.  
7.Extension Option.  
(a)    Right to Extend.  On the conditions (which conditions Landlord may waive by written notice to Tenant) that both at the time of exercise of the Sixth Amendment Extension Option (as hereinafter defined) and as of the commencement of the Second Extension Term (as hereinafter defined) (i) there exists no monetary or other material Event of Default (“Event of Default” being defined in Section 7.1 of the Original Lease), and (ii) the Lease is still in full force and effect, Landlord grants Tenant the option (the “Sixth Amendment Extension Option”) to extend the Term of the Lease with respect to the entire Premises for one (1) additional period of ten (10) years (the “Second Extension Term”) subject to each and all of the terms and conditions set forth in this Section 7.  All other extension options under the Lease (including Section 8.20 of the Original Lease and Section 4 of the Third Amendment) are hereby extinguished, and no option to extend the term of the Lease exists except as set forth in this Section 7. 
i.    Effect of Assignment or Sublease.  The Sixth Amendment Extension Option may not be exercised by, assigned or otherwise transferred to any person or entity voluntarily or involuntarily, except the Tenant named in the Lease (or a Successor Entity that succeeds to the interest of Tenant by assignment in accordance with Section 5.6 of the Original Lease).  The parties hereto agree that if Tenant assigns any of its interest in the Lease or subleases more than 50% of the rentable square area of the Premises to any person or persons, in the aggregate, for all or substantially all of the remaining Term (meaning that less than twenty-one (21) months will remain in the then-Term of this Lease when the sublease expires) other than pursuant to a Successor Entity (as that term is defined in the Original Lease), this Sixth Amendment Extension Option shall terminate immediately without the need for any act or notice by either party to be effective.
ii.    Manner of Notice.  In order to exercise the Sixth Amendment Extension Option, Tenant shall deliver to Landlord written notice (the “Extension Notice”) of the exercise of the Sixth Amendment Extension Option not later than July 31, 2028 and not sooner than April 30, 2028, time being of the essence.  If an Extension Notice is not so delivered, Tenant's Sixth Amendment Extension Option shall automatically expire.  The giving of an Extension Notice shall be deemed to be a binding exercise of Tenant’s extension option, subject only to the right to rescind the same as expressly provided below.
iii.    Effect of Default.  Tenant's right to exercise the Sixth Amendment Extension Option shall be suspended at the election of Landlord during any period in which a monetary or other material Event of Default has occurred and is continuing, but the period of time within which the Sixth Amendment Extension Option may be exercised shall not be extended.  Notwithstanding Tenant's due and timely exercise of the Sixth Amendment Extension Option, if, after such exercise and prior to the effective date of the Second Extension Term a monetary or other material Event of Default occurs under this Lease that is not cured within the applicable grace period, if any, and Landlord terminates this Lease, then Tenant's exercise 


5
EAST\141300457.11 







of the Sixth Amendment Extension Option shall be of no force and effect and its rights hereunder shall terminate.
iv.    Rent.  The Annual Fixed Rent for the Second Extension Term shall be equal to the then-prevailing fair market fixed annual rental rate (such prevailing fair market rental rate, the “Market Rent”) for the Premises on an “as is” basis, taking into account market increases during the Term and all other market concessions for tenant renewals in comparable office and R&D complexes as well as quality of office and R&D complex product with comparable amenities to the Complex in the Route 128 North Submarket and all other then relevant factors.  During the Second Extension Term, the Additional Rent for the Premises shall continue to be payable as provided in the Lease and all of the terms, conditions and covenants of the Lease shall apply.
(b)    Market Rent Notice.  If Tenant properly exercises its Sixth Amendment Extension Option, Landlord shall provide Tenant with written notice (the “Market Rent Notice”) of the Landlord’s good faith determination of the Market Rent for the entire Second Extension Term within fifteen (15) business days of Landlord’s receipt of the Extension Notice.  Tenant shall respond in writing to Landlord’s Market Rent Notice within thirty (30) days following the Market Rent Notice (the “Tenant Response Period”) stating that (a) Tenant agrees with the Market Rent determined by Landlord, (b) Tenant elects to rescind its Extension Notice (in which case Tenant’s rights under this Section 7 shall terminate and be of no further force and effect), or (c) Tenant elects to dispute Landlord’s determination of Market Rent pursuant to Section 7(c), below.  If the parties agree on the Base Rent for the Second Extension Term during the Tenant Response Period or Tenant gives the notice described in clause (a) of the immediately preceding sentence, Landlord and Tenant shall exercise reasonable efforts to execute an amendment to the Lease within twenty (20) business days following Landlord’s submission of a proposed amendment to Tenant and stating the Second Extension Term, the Base Rent and any related terms and conditions.  Notwithstanding the foregoing, failure to execute such an amendment shall not impact the binding nature of Tenant’s exercise of the Sixth Amendment Extension Option.  If Tenant gives the notice described in clause (c) of this Section 7(b), above, then the Market Rent shall be determined in accordance with Section 7(c).
(c)    Dispute.  If the determination of Market Rent is to be made pursuant to this Section 7(c), then the Market Rent shall be determined by arbitration as set forth below in order to establish the Base Rent for the Second Extension Term and Landlord and Tenant shall be bound by the results of the arbitration.  Notwithstanding the submission of the issue of Market Rent to arbitration, if such Base Rent has not been established pursuant to Section 7(d) below prior to the commencement of the Second Extension Term, Base Rent for the next ensuing Lease Year of the Term shall be paid at the Base Rent established by Landlord in its Market Rent Notice until the arbitration is completed.  If, upon completion of the arbitration, it is determined that Market Rent is less or more than that set by Landlord, then an adjustment based upon such lower or greater rent shall be made based on the number of months therefor paid by Tenant.  In no event shall the extension of the Term be affected by the determination of the Base Rent, such exercise of the Sixth Amendment Extension Option being fixed at the time at which Tenant delivers the Extension Notice, subject only to Tenant’s rescission right under Section 7(b) above.

EAST\141300457.11 







(d)    Arbitration.  When the terms of this Sixth Amendment provide that Market Rent shall be determined by arbitration, the following arbitration procedures shall apply:
i.    Selection of Arbitrators.  Within five (5) business days following the end of the Tenant Response Period, each of Tenant and Landlord shall choose a licensed commercial real estate broker who has at least twelve (12) years' full-time experience in commercial leasing in the Route 128 North submarket and shall notify the other party in writing of its selection.  If a party does not appoint an arbitrator within such five (5) business day period and such failure is not cured within five (5) business days following a written request for such appointment by the other party, then the single broker appointed shall be the sole arbitrator and shall establish the Market Rent for the Extension Term;
ii.    Selection of Third Arbitrator.  If the two (2) arbitrators are appointed by the parties as stated above, they shall meet within five (5) business days following their appointment in accordance with Subsection 7(d)(i) above, and the arbitrators selected shall select a third arbitrator meeting the qualifications as set forth in Subsection 7(d)(i) above; if the two (2) arbitrators fail to select the third arbitrator within such time period, such third arbitrator shall be appointed by the President of the Greater Boston Real Estate Board or, if it ceases to exist, a similar organization reasonably selected by Landlord.  The third arbitrator, however selected, shall be a person who has not previously acted in any capacity for either party;
iii.    Decision by Arbitrators.  Within fifteen (15) business days after their appointment, the three (3) arbitrators selected pursuant to the terms hereof shall determine the Market Rent for the Premises for the Second Extension Term, and shall notify Tenant and Landlord of such determination within three (3) days thereafter, which determination shall be final and binding upon Tenant and Landlord.  If the arbitrators are unable to agree upon the Market Rent, the Market Rent will be deemed to be the average of the Market Rents proposed by the arbitrators, except that (i) if the lowest proposed Market Rent is less than ninety percent (90%) of the second to lowest proposed Market Rent, the lowest proposed Market Rent will automatically be deemed to be ninety percent (90%) of the second to lowest proposed Market Rent and (ii) if the highest proposed Market Rent is greater than one hundred ten percent (110%) of the second to highest proposed Market Rent, the highest proposed Market Rent will automatically be deemed to be one hundred ten percent (110%) of the second to highest proposed Market Rent;
iv.    Allocation of Expenses.  Landlord and Tenant shall each pay one-half (1/2) of the expense of the third arbitrator’s fees and each shall pay 100% of the fees of the arbitrator appointed by each respective party.
v.    Guidelines for Arbitration.  For the avoidance of doubt, for the purpose of determining Market Rent pursuant to arbitration, the parties shall use the definition of Market Rent set forth in Section 7(a)(iv).

8.Expansion Rights in Buildings 4, 16 and 18.  
Section 8.28 of the Original Lease is hereby amended and restated in its entirety as follows:


Section 8.28. Right of First Offer


(A)On the conditions (which conditions Landlord may waive by written notice to Tenant at any time), that as of both the time that any portion of the RFO Premises (as hereinafter defined) becomes available for reletting (as hereinafter defined) and as of the commencement date of Tenant’s leasing of such portion of the RFO Premises: (i) Tenant directly leases from Landlord at least 100,000 square feet of rentable floor area, (ii) no monetary or other material Event of Default of Tenant exists and there have been no more than two (2) monetary or other material Event of Default occurrences during the Lease Term, (iii) the Lease is still in full force and effect, and (iv) Tenant has neither assigned the Lease nor sublet more than fifty percent (50%) of the Total Rentable Floor Area of the Buildings (except for an assignment or sublease under Section 5.6.1 of the Lease or an occupancy permitted pursuant to Section 5.6.6 of the Lease), Tenant shall have a right of first offer (“Right of First Offer”) to lease the RFO Premises, as hereinafter defined.  


For the purposes hereof, the “RFO Premises” shall be defined as any and all space in  Building 4 (also known as 4 Crosby Drive), Building 16 (also known as 16 Crosby Drive), and Building 18 (also known as 18 Crosby Drive) of the Complex as and when such space becomes available for reletting (as hereinafter defined).


(B)    When any portion of the RFO Premises becomes available for reletting (as hereinafter defined), Landlord shall notify Tenant (“Landlord’s RFO Premises Notice”) of the availability of such space, which notice shall contain the size, configuration, location and date of availability of such portion of the RFO Premises, the Annual Market Rent, and the other business terms upon which Landlord is willing to so lease such space.  The “net effective rental rate” set forth in Landlord’s RFO Premises Notice shall mean and be expressed in terms of (i) the Annual Market Rent for the applicable portion of the RFO Premises quoted by Landlord, (ii) the triple-net basis of this Lease for Operating Expenses and Taxes, (iii) the free rent or “build-out” period, if any, after the commencement of the lease term, (iv) the tenant improvement allowance, if any, and (v) the length of the lease term, which shall hereinafter be referred to as “Landlord’s Offered Rental Terms.” 


For the purposes hereof:


(1)    The “Annual Market Rent” shall be the annual fair market rent for the applicable portion of the RFO Premises as of the date when the same becomes available for reletting, based upon the use of such space as first class office/research and development space utilizing properties of similar character within the Boston Northwest Suburban Market and based on the Market Rate (as defined in Section 7 above of this Sixth Amendment) for such portion of the RFO Premises.  


(2)    A portion of the RFO Premises shall be deemed “available for reletting” when Landlord, in its sole judgment, determines that the then current tenant of such portion of the RFO Premises will vacate the applicable portion of the RFO Premises at the expiration or earlier termination of such tenant’s lease, provided that with 


8
EAST\141300457.11 







respect to 4 Crosby Drive and 18 Crosby Drive the applicable portion of the RFO Premises shall also be deemed to be “available for lease” when the then-current tenant’s right to extend or renew, if any, contained within its lease expires in accordance with the terms of the applicable lease agreement without having been exercised or such right otherwise has been waived in writing by such tenant.  


In connection with the foregoing, it is understood and agreed that Tenant’s rights under this Section 8 shall be subject and subordinate to the rights of the existing tenants in 4 Crosby Drive, 16 Crosby Drive and 18 Crosby Drive as of the date of this Sixth Amendment (the “Existing Tenants”) as set forth on Exhibit O attached to the Sixth Amendment (the terms of any leases with the Existing Tenants, including, but not limited to, the original terms thereof and options to extend the terms thereof contained in lease documents executed prior to the date hereof are hereinafter individually and collectively called the “Existing Leases”). 


(C)    If Tenant wishes to exercise Tenant's Right of First Offer, Tenant shall do so, if at all, by giving Landlord notice (“Tenant’s RFO Exercise Notice”) within five (5) business days after receipt of Landlord’s RFO Premises Notice, time being of the essence, of Tenant's desire to lease all (but not less than all) of the space designated in Landlord’s RFO Premises Notice.  Tenant shall, in Tenant’s RFO Exercise Notice, specify whether it shall be leasing the applicable portion of the RFO Premises for (1) the lease term specified in Landlord’s RFO Premises Notice or (2) a lease term that is coterminous with the Term of the Lease with respect to the Existing Premises (it being understood and agreed that if less than sixty (60) months then remain in the Lease Term at the time Tenant delivers the Tenant’s RFO Exercise Notice electing to lease the applicable portion of the RFO Premises for a term to be coterminous with the Lease Term with respect to the Existing Premises and if such period is shorter than the lease term offered in Landlord’s RFO Premises Notice, Tenant must simultaneously exercise its extension option under Section 7 of this Sixth Amendment with its exercise of its rights under this Section 8 and if no such extension option is then available to Tenant then the term with respect to the applicable portion of the RFO Premises shall automatically be as specified in Landlord’s RFO Premises Notice) (the lease term as determined under subsection (1) or (2) being hereinafter referred to as the “Designated RFO Lease Term”).  


If Tenant shall give a Tenant’s RFO Exercise Notice the same shall constitute an agreement to enter into an instrument in writing to lease the portion of the RFO Premises identified in Landlord’s RFO Premises Notice and Landlord and Tenant will exercise reasonable efforts to enter into an amendment to the Lease memorializing the expansion of the Premises within thirty (30) days after receipt of a first draft of such amendment from Landlord adding the applicable portion of the RFO Premises to the Premises upon all of the same terms and conditions in this Lease, except to the extent inconsistent with the provisions of this Section 8 and except that (x) the Annual Fixed Rent shall be equal to the Annual Market Rent as quoted by Landlord, (y) the lease term with respect to the applicable portion of the RFO Premises shall be the Designated RFO Lease Term, and (z) the lease amendment shall also reflect such other business terms as were set forth in Landlord’s RFO Premises Notice.  For the avoidance of doubt, Tenant’s RFO Exercise Notice shall be binding regardless of whether the written instrument contemplated in the previous sentence is executed. 


(D)    If Tenant shall not timely exercise its rights under this Section 8 within such period, time being of the essence in respect to such exercise, Landlord shall be free to lease such 


9
EAST\141300457.11 







portion of the RFO Premises for two hundred seventy (270) days after the date of Landlord’s RFO Premises Notice for a net effective rental rate which is not less than 90% of Landlord’s Offered Rental Terms contained in Landlord’s RFO Premises Notice without again offering such space to Tenant for lease; provided, however, that (i) Landlord shall reoffer the applicable RFO Premises to Tenant in accordance with the terms and provisions of this Section 8 if (a) Landlord does not so lease such space during such two hundred seventy (270) day period, or (b) if Landlord proposes to lease such space in larger or smaller increments, or (c) if Landlord proposes to lease such space during such two hundred seventy (270) day period for a net effective rental rate which is less than 90% of Landlord’s Offered Rental Terms contained in Landlord’s RFO Premises Notice, and (ii) the terms of this Section 8 shall continue to apply to the remainder of the RFO Premises, if any, not included in Landlord’s RFO Premises Notice and to RFO Premises included in Landlord’s RFO Premises Notice and not leased by Tenant which is subsequently leased to another tenant in accordance with this Section 8 and thereafter becomes available for reletting (i.e. this is a continuous Right of First Offer).


(E)    If Tenant shall exercise any such Right of First Offer and if, thereafter, the then occupant of the portion of the RFO Premises with respect to which Tenant shall have so exercised such right wrongfully fails to deliver possession of such premises at the time when its tenancy is scheduled to expire, Landlord shall use reasonable efforts and due diligence (which shall be limited to the commencement and prosecution of eviction proceeding within sixty (60) days after the date on which the hold-over commences, but shall not require the taking of any appeal) to evict such occupant from such space and to recover from such occupant any Hold-Over Premium (as defined below) payable by such occupant.  In such event, the commencement of the term of Tenant's occupancy and lease of such additional space shall, in the event of such holding over by such occupant, be deferred until possession of the additional space is delivered to Tenant.  The failure of the then occupant of such premises to so vacate shall not constitute a default or breach by Landlord and shall not give Tenant any right to terminate the Lease or to deduct from, offset against or withhold Annual Fixed Rent or Additional Rent (or any portions thereof); except that if such holdover exceeds one hundred eighty (180) days, then Tenant may cancel the exercise of its option to lease the applicable portion of the RFO Premises by giving to Landlord a written cancellation notice (provided, however, that if Landlord delivers such portion of the RFO Premises to Tenant on or before the date thirty (30) days after Landlord receives such cancellation notice, such cancellation notice shall be void and without further force or effect).


Alternatively, in lieu of canceling the exercise of such option, Tenant shall have the right to require Landlord to pay to Tenant the net (i.e. net of the costs and expenses, including, attorneys’ fees, incurred by Landlord in obtaining such Hold-Over Premium) amount of any Hold-Over Premium received by Landlord from such hold-over occupant relative to periods from and after the sixty-first (61st) day of any hold-over, when and if Landlord receives any such payment.  For the purposes hereof, the term “Hold-Over Premium” shall be defined as the amount (if any) which a hold-over occupant of any portion of the RFO Premises is required to pay to Landlord in respect of its hold-over in the premises (whether characterized as rent, damages, or use and occupation) in excess of the amount of fixed rent and other charges which the tenant under whom such occupant claims would have been required to pay to Landlord had the term of such tenant’s lease been extended throughout the period of such hold-over at the same rental rate as such tenant was required to pay during the last month of its tenancy.


10
EAST\141300457.11 









In the event that Tenant elects to cancel its exercise of its option hereunder as the result of a holding over by the existing occupant of the applicable portion of the RFO Premises, Landlord shall reoffer the space to Tenant at such time as the hold-over tenant is evicted from the space upon the same terms and conditions as set forth in Tenant’s RFO Exercise Notice with respect to such space (and otherwise in accordance with the terms and provisions of this Section 8).


(F)    Landlord shall use reasonable efforts to keep Tenant informed with semi-annual written updates of the expected availability of the leaseable areas in the RFO Premises; provided, however, that Landlord’s failure to provide such updates shall in no way be deemed to be a default of Landlord under this Lease or otherwise give rise to any liability on Landlord’s part.

Beyond delivery of Landlord’s 14 Crosby Leasing Notice, Landlord shall have no further obligation to Tenant with respect to the 14 Crosby Vacant Space, and the rights of Tenant set forth in this Section 8.29 shall not constitute rights in real property.  Except as amended and restated in this Section 8 of the Sixth Amendment, the provisions of Section 8.29 of the Original Lease are deleted and are of no further force or effect.
10.Site.  Exhibit A to the Original Lease is hereby deleted in its entirety and replaced with the Description of Site attached hereto as Exhibit A.  Exhibit A-1 to the Original Lease is hereby deleted in its entirety and replaced with the Site Plan of Complex attached hereto as Exhibit A-1.

For purposes of this Exhibit C, “Tenant SA Delay” shall mean any delay in the design, permitting or performance of the Landlord’s BMS Work or the Curtainwall Work to the extent that such delay is actually caused by any act or, where there is a duty to act under this Lease, any failure to act by Tenant or Tenant’s contractors, architects, engineers, or anyone else engaged by or on behalf of Tenant as hereinafter provided.  Tenant SA Delay shall expressly include (without the need for any further notice to Tenant) Tenant’s failure to comply with the dates set forth in the construction and phasing schedule for the Curtainwall Work agreed to by Landlord and Tenant or any subsequent changes to such phasing schedule mutually agreed to by Landlord and Tenant or the period for providing any response to a request by landlord expressly set forth in this Attachment #1 (“Deemed Delays”).  Notwithstanding the foregoing, except for failure to act in a timely manner (including in accordance with the dates set forth in the construction and phasing schedule for the Curtainwall Work) by Tenant or Tenant’s contractors, architects, engineers, or anyone else engaged by or on behalf of Tenant, in no event shall any act or occurrence giving rise to a delay be deemed a Tenant SA Delay as herein provided unless and until Landlord has given Tenant written notice (the “Tenant SA Delay Notice”) advising Tenant: (x) that a Tenant SA Delay is occurring and setting forth Landlord’s good faith estimate as to the likely length of such Tenant SA Delay; (y) of the basis on which Landlord has determined that a Tenant SA Delay is occurring; and (z) the actions which Landlord believes that Tenant must take to eliminate such Tenant SA Delay.  Except with respect to Deemed Delays, no event shall be deemed to be a Tenant SA Delay if Tenant rectifies the situation causing the Tenant SA Delay within forty-eight (48) hours after delivery of the Tenant SA Delay Notice (which for the purposes of determining receipt may be delivered by hand or by email to Tenant’s Construction Representative (as defined in Section 7 of Exhibit D), with copies to follow to Tenant within five (5) days thereafter in accordance with the notice provisions of the Lease); provided, however, that if Tenant shall fail to eliminate the delay within the aforesaid 48-hour period, then the 48-hour cure period shall be included in the period of time charged to Tenant pursuant to such Tenant SA Delay Notice (it being understood and agreed that if Tenant shall in fact eliminate the Tenant SA Delay within the 48-hour cure period, no Tenant SA Delay shall be deemed to have occurred for the purposes of this Exhibit C for the first three (3) instances of Tenant SA Delay).  In connection with the foregoing, Landlord and Tenant (together with their respective contractors and representatives, as appropriate) agree to hold periodic job meetings to discuss the performance and scheduling of the Curtainwall Work and any changes to the construction and phasing schedule for the Curtainwall Work that are reasonably necessary.  Upon substantial completion of the Curtainwall Work, Tenant’s Construction Representative shall accompany Landlord’s Construction Representative and Landlord’s architect on a walkthrough to inspect the Curtainwall Work on a date within 10 business days of a date reasonably designated by Landlord. Upon Tenant’s request, 


C-3
EAST\141300457.11 


 



Landlord shall provide Tenant with confirmation of the date of substantial completion for purposes of measuring the 345 day period referenced in the immediately following paragraph.
Landlord shall cause the Contractor to provide a customary one-year construction warranty for the Curtainwall Work, which shall provide that the Curtainwall Work will conform to the requirements of the Curtainwall Work Plans and will be free from defects.  The Contractor’s warranty shall not include remedies for damage or defect caused by Tenant or anyone claiming by, through or under Tenant, alterations to the Curtainwall Work performed by or on behalf of Tenant, or normal wear and tear under normal usage.  In the case of defects under the Contractor’s warranty, Tenant shall be deemed to have waived any claim for correction or cure for such defect on the date that is 345 days following the completion of such work as determined by Landlord’s architect if Tenant has not then given written notice of such defect to Landlord.  Landlord shall cause Landlord’s contractor to remedy, repair or replace any such defects identified by Tenant within such 345-day period, such action to occur as soon as practicable during normal working hours (unless such work will adversely affect Tenant’s operations in the affected portions of the Premises, in which case the parties shall cooperate to permit such work to be performed after-hours) and so as to avoid any unreasonable interruption of Tenant’s use of the affected portions of the Premises.  If timely and adequate notice has been given and if Landlord has other guarantees, contract rights, or other claims against contractors, materialmen or architects, Landlord shall, with regard to any such defects, exercise all reasonable efforts to enforce such guarantees or contract rights.  The foregoing shall constitute Landlord’s entire obligation with respect to all defects in the Landlord Work (provided, however, that nothing in this paragraph shall relieve the Landlord of its repair and maintenance obligations under Section 4.1 of the Lease).   During the period for correction of the Curtainwall Work in accordance with this paragraph, if the Tenant fails to notify the Owner and give the Owner an opportunity to cause the contractor to make the correction, the Tenant waives the rights to require correction by the contractor and to make a claim for breach of Landlord’s obligations under this paragraph for such nonconforming item of Curtainwall Work (nothing in this sentence being deemed to relieve Landlord of its repair and maintenance obligations under the Lease, however).
		
	1.
	Notwithstanding anything contained in this Lease to the contrary, if Landlord shall fail to substantially complete (y) the Landlord’s BMS Work on or before June 1, 2018 (which date shall be extended automatically for Tenant SA Delay and for such periods of time as Landlord is prevented from completing the same by reason of Force Majeure), or (iii) the Curtainwall Work by November 1, 2018 (which date shall be extended automatically for Tenant SA Delay and for such periods of time as Landlord is prevented from completing the same by reason of Force Majeure), then, in either such event, Tenant, as its sole remedy at law, equity, or under this Lease, shall be entitled to a credit against the Annual Fixed Rent payable under this Lease in an amount equal to Five Hundred Dollars ($500.00) per day for each day from and after the applicable completion date set forth above (i.e., June 1, 2018 (as it may be extended) with respect to Landlord’s BMS Work or November 1, 2018 (as it may be extended) with respect to the Curtainwall Work) to the date of completion of the Landlord’s BMS Work or the Curtainwall Work, as applicable.  Additionally, if Landlord’s performance of any portion of the Curtainwall Work requires Tenant to vacate and not use a portion of the Protected Area of the Premises for in excess

of six (6) months, subject to extension for Tenant SA Delay and Force Majeure, then the Annual Fixed Rent for the applicable portion of the Protected Area of the Premises plus an additional ten percent (10%) of the Premises as measured in rentable square feet shall abate from and after the expiration of such six (6) month period (as so extended) until such time as Tenant is reasonably able to reoccupy and conduct business in such affected areas of the Premises.  In the event that Landlord disputes Tenant’s right to a rent abatement pursuant to this paragraph, such dispute may be submitted to arbitration by either party pursuant to Section 8 of Exhibit D to this Sixth Amendment.

EXHIBIT D
WORK LETTER – SIXTH AMENDMENT TENANT ALTERATIONS
1.    Following the Effective Date, Tenant shall have the right to perform alterations and improvements in the Premises (the “Sixth Amendment Tenant Alterations”).  Notwithstanding the foregoing, Tenant and its contractors shall not have the right to perform the Sixth Amendment Tenant Alterations in the Premises unless and until Tenant has complied with all of the terms and conditions of Section 5.14 of the Lease, including Landlord’s right to approve (a) the final plans for the Sixth Amendment Tenant Alterations, and (b) the insurance coverage obtained by Tenant and its contractors in connection with the Sixth Amendment Tenant Alterations.  In addition, Landlord shall have the right to approve, in its reasonable discretion, the contractors (each, a “Contractor”) to be retained by Tenant to perform the Sixth Amendment Tenant Alterations.  Tenant shall be responsible for all elements of the plans for the Sixth Amendment Tenant Alterations (including, without limitation, compliance with law, functionality of design, the structural integrity of the design, the configuration of the premises and the placement of Tenant's furniture, appliances and equipment), and Landlord's approval of such plans shall in no event relieve Tenant of the responsibility therefor.  Landlord's approval of the contractors to perform the Sixth Amendment Tenant Alterations shall not be unreasonably withheld.  Landlord's approval of the general contractor to perform the Sixth Amendment Tenant Alterations shall not be considered to be unreasonably withheld if any such general contractor (i) does not have trade references reasonably acceptable to Landlord, (ii) does not maintain insurance as required by Landlord, (iii) does not have the ability to be bonded for the work in an amount satisfactory to Landlord, (iv) does not provide current financial statements reasonably acceptable to Landlord, or (v) is not licensed as a contractor in the state and municipality in which the Premises is located.  Tenant acknowledges the foregoing is not intended to be an exclusive list of the reasons why Landlord may reasonably withhold its consent to a general contractor.
With respect to Sixth Amendment Tenant Alterations constructed within the two years after the Effective Date, Landlord shall review Tenant’s plans and specifications for the Sixth Amendment Tenant Alterations (the “Tenant’s Plans”) and, if Tenant’s request for approval indicates in bold, capitalized text that states “THIS IS A TIME SENSITIVE REQUEST AND LANDLORD MAY BE DEEMED TO APPROVE THE SAME IF IT FAILS TO RESPOND TO WITHIN FIFTEEN (15) BUSINESS DAYS AFTER RECEIPT,” within fifteen (15) business days after receipt thereof Landlord shall provide Tenant with written notice of either (i) its approval of the Tenant’s Plans, (ii) its disapproval of the same with an explanation therefor, or (iii) the need for additional information in order to review and approve the same.  In its approval of the Tenant’s Plans, Landlord shall specify those alterations, additions and improvements that must be removed by Tenant at the expiration or earlier termination of the Term, if any, unless Landlord subsequently elects to waive such obligation to remove such alterations, additions and improvements.  If Landlord fails to respond within the aforementioned 15 business day period, then Tenant may send Landlord a second request that indicates in bold, capitalized text that states “THIS IS A TIME SENSITIVE REQUEST AND LANDLORD SHALL BE DEEMED TO APPROVE THE SAME IF IT FAILS TO RESPOND TO WITHIN FIVE (5) BUSINESS DAYS AFTER RECEIPT”. Landlord’s failure to so respond within said five (5) business day period shall be deemed to constitute Landlord’s approval of the Tenant’s 


D-1
EAST\141300457.11 


 



Plans and determination that the alterations, additions and improvements shown thereon do not need to be removed by Tenant at the expiration or earlier termination of the Term (except to the extent that such removal would be required pursuant to clause (x) of Section 5.2 of the Lease with respect to Tenant’s computer, telephone and other communications systems and equipment). Notwithstanding the foregoing or anything in the Lease to the contrary, Tenant shall be required in all events to remove any internal stairwells, raised floors, supplemental HVAC, specialized fire suppression systems, kitchens, bathrooms and showers, and any structural improvements made by Tenant as part of the Sixth Amendment Tenant Alterations.
Notwithstanding anything contained herein to the contrary, it is understood and agreed that Tenant may retain contractors and subcontractors that use union or non-union labor in connection with the construction of the Sixth Amendment Tenant Alterations.  Tenant shall be responsible for maintaining labor harmony among its contractors and subcontractors and other contractors and subcontractors performing work at the Building, if any.  For Sixth Amendment Tenant Alterations costing $3,000,0000 or less in or one or more related projects and undertaken within two years after the Effective Date, no bonds or other security shall be required in connection with Tenant’s performance of such Sixth Amendment Tenant Alterations.  
2.    Tenant shall pay to Landlord, within ten (10) days after Landlord's written demand, a construction management fee equal to one percent (1%) of the hard cost of the Sixth Amendment Tenant Alterations to compensate Landlord for reviewing the plans for the Sixth Amendment Tenant Alterations and for costs incurred by Landlord in facilitating completion of the Sixth Amendment Tenant Alterations.  No other plan review or other fees shall be charged by Landlord with respect to the Sixth Amendment Tenant Alterations notwithstanding anything in the Lease to the contrary, including Section 5.14 of the Lease.   Landlord reserves the right to deduct such fee from the Sixth Amendment Construction Allowance (defined below).  The construction management fee set forth in this section shall supersede any contrary provision of the Lease in so far as concerns the Sixth Amendment Tenant Alterations. 
3.    Provided there is no monetary or material non-monetary Event of Default in existence and continuing under the Lease, Landlord agrees to provide Tenant with an allowance of up to Eight Million Three Hundred Forty Seven Thousand Four Hundred Forty Dollars ($8,347,440.00) (the “Sixth Amendment Construction Allowance”) toward the cost of performing the Sixth Amendment Tenant Alterations.  The Sixth Amendment Construction Allowance may only be used for “Eligible Costs,” which are: (a) the cost of preparing design and construction documents and mechanical and electrical plans for the Sixth Amendment Tenant Alterations (which may not exceed 25% of the Sixth Amendment Construction Allowance), and (b) hard costs in connection with the Sixth Amendment Tenant Alterations.  
The Sixth Amendment Construction Allowance may be advanced to fund Eligible Costs.  In no event, however, shall the Sixth Amendment Construction Allowance be used for (x) payments to Tenant or any affiliates of Tenant, (y) the purchase of any movable furniture equipment or personal property, or (z) costs resulting from any default by Tenant of its obligations under this Lease.  Landlord shall, subject to compliance with all of the other terms, conditions and provisions of the 


D-2
EAST\141300457.11 


 



Lease, make disbursements of the Sixth Amendment Construction Allowance (hereinafter, each a “Disbursement”) to Tenant in installments in accordance with the following terms and conditions:
(i)    Disbursements shall be made, at Tenant’s request to Landlord, either to Tenant or, at Tenant’s election,  to the applicable contractors, vendors and other service providers performing the Sixth Amendment Tenant Alterations as Tenant may designate or request (provided that any such payment made directly to a contractor, vendor, or other service provider shall be conditioned upon the contractor, vendor or other provider entering into a letter agreement reasonably satisfactory to Landlord confirming that such payments are being made as a matter of convenience and do not create any obligation of Landlord to pay such sums to such contractor, vendor or other service provider), no more frequently than once per month, in minimum increments of $75,000.00 (except for the final Disbursement), on the basis of written requests made in accordance with the method described below, and Landlord shall act upon such requests within thirty (30) days following the receipt of a written request for a Disbursement, which action shall be either (A) funding the requested Disbursement, or (B) specifying the basis for not funding (provided, however, that Landlord shall fund any undisputed portion of the requested Disbursement) and, when applicable, requesting reasonable additional information and reasonable supporting documentation.
(ii)    Disbursements shall require the following requisitions, certifications and waivers:  (1) an appropriate AIA requisition form reasonably approved by Landlord with respect to work performed pursuant to Tenant’s construction contract with its general contractor; (2) invoices from Tenant’s service providers, showing in reasonable detail the cost of the item in question or of the improvements installed to date in the Premises and, where applicable evidence of prior payments; (3) lien waivers in the form attached as Addendum #1 to this Work Letter; (4) evidence reasonably acceptable to Landlord of prior payments for amounts previously disbursed out of the Sixth Amendment Construction Allowance (to the extent not previously provided to Landlord); and (5) certifications from Tenant that the amount of the requisition in question does not exceed the cost of the items, services and work covered by such certification.  In the event that any portions of the Sixth Amendment Construction Allowance reflected on a particular requisition are to be funded directly to Tenant, as Tenant may designate or request, such requisition shall be accompanied by evidence reasonably satisfactory to Landlord that the items, services and work covered by such requisition have been fully paid by Tenant.  Landlord shall have the right, upon reasonable advance notice to Tenant, to inspect Tenant’s books and records relating to each requisition in order to verify the amount thereof.  
(iii)    Each Disbursement shall be made in an amount equal to the product of (x) Landlord’s Percentage (as hereinafter defined) multiplied by (y) the lesser of:  (A) the amount requested, or (B) the amount actually payable to, as applicable, the Contractor or subcontractor(s) or other third party, in each case including any applicable retainage to be released in respect of work and materials satisfactorily completed and in place with respect to that particular request for a Disbursement (exclusive of work and materials to the extent included in any prior funded requests for a Disbursement), but in all cases subject to a five percent (5%) retention until all conditions to the final Disbursement are satisfied as set forth below.  “Landlord’s Percentage” shall mean a fraction expressed as a percentage, the numerator of which is the total amount of the Sixth Amendment 


D-3
EAST\141300457.11 


 



Construction Allowance and the denominator of which is the total cost of all Eligible Costs.  Tenant shall fund the remainder in each instance.
(iv)    Landlord may withhold or refuse to pay any Disbursement hereunder if (i) a Notice of Contract has been filed under Section 4 of Chapter 254 of the Massachusetts General Laws, as amended (the “Mechanic’s Lien Law”), unless with respect to the subject requisition, an accurately completed and valid Lien Form has been provided to Landlord and is deemed reasonably acceptable to Landlord and otherwise complies with applicable Laws, or if any other statutory lien has been filed or established relating to claims for labor, materials, or supplies, whether under the Mechanic’s Lien Law or otherwise.  
(v)    No Disbursements will be made for materials prior to the incorporation of the materials into the Premises.  
(vi)    Any disputes under this Exhibit D, Section 3 shall be submitted to arbitration in accordance with the terms of Section 8, below. 
(vii)    The requisition for the final Disbursement to pay the retainage, shall also require: (A) a certificate from Tenant and Tenant’s architect that the Sixth Amendment Tenant Alterations have been completed in accordance with Tenant’s Plans; (B) receipt of a permanent certificate of occupancy for the Premises (if applicable); (C) delivery of the record set of as-built plans maintained by Tenant’s Contractor; (D) satisfaction of all conditions for final payment under the applicable construction contract, (E) final lien waivers from the Contractor (which may be conditioned upon receipt of payment), in the form required hereunder; (E) final lien waivers in the form required hereunder (which may be conditioned upon receipt of payment) from each sub-contractor, supplier, and any other party entitled to claim a lien with respect to the Sixth Amendment Tenant Alterations (other than the Contractor) who performs work in excess of $10,000; and (F) to the extent a lien waiver has not been provided as to the remaining amounts due under the applicable construction contract, the expiration of all statutory lien periods with no lien having been filed with respect to the Premises, the Building, or the Complex which remain outstanding.
4.    Notwithstanding anything herein to the contrary, Landlord shall not be obligated to disburse any portion of the Sixth Amendment Construction Allowance, if applicable, during the continuance of an uncured Event of Default under the Lease, and Landlord's obligation to disburse shall only resume when and if such default is cured.  If (a)Tenant’s request for disbursement contains, in bold and prominent print, a legend stating that “FAILURE TO RESPOND WITHIN     THIRTY (30) DAYS MAY RESULT IN AN OFFSET AGAINST RENT DUE PURSUANT TO EXHIBIT D OF THE SIXTH AMENDMENT TO THE LEASE,” and Landlord fails to respond within such thirty (30) day period, and Landlord thereafter fails to respond to such request within two (2) business days of a second notice from Tenant containing such legend, or (b) Landlord has timely disputed Tenant’s demand and has thereafter failed to pay Tenant the amount of any final, unappealable judgement against Landlord within thirty (30) days after the issuance thereof, then Tenant may offset the amounts due from Landlord to Tenant under this Section 2 of Exhibit D against Fixed Rent payable under this Lease until Tenant is paid in full.  Notwithstanding the foregoing, Tenant shall have no right to reduce any monthly installment of Fixed Rent by more than twenty percent (20%) of the amount of Annual Fixed Rent that would otherwise have been due and payable by 


D-4
EAST\141300457.11 


 



Tenant to Landlord, unless the aggregate amount of such deductions over the remainder of the Term of the Lease (as the same may have been extended) will be insufficient to fully reimburse Tenant for the amount demanded by Tenant, in which event Tenant may effect such offset by making deductions from each monthly installment of Fixed Rent in equal monthly amounts over the balance of the remainder of the Term.
5.    In no event shall the Sixth Amendment Construction Allowance be used for the purchase of equipment, furniture or other items of personal property of Tenant.  In the event Tenant does not submit to Landlord a written request for payment of the entire Sixth Amendment Construction Allowance (together with all of the documents and certificates required for such payment) by February 28, 2021, any portion of the Sixth Amendment Construction Allowance not disbursed to Tenant shall accrue to the sole benefit of Landlord, it being understood that Tenant shall not be entitled to any credit, abatement or other concession in connection therewith.  Tenant shall be responsible for all applicable state sales or use taxes, if any, payable in connection with the Sixth Amendment Tenant Alterations and/or the Sixth Amendment Construction Allowance.  
6.    Tenant agrees to accept the Premises in its “as-is” condition and configuration, without representation or warranty by Landlord or anyone acting on Landlord's behalf, it being agreed that Landlord shall not be required to perform any work (except the Landlord Work set forth in Exhibit C to the Sixth Amendment) or incur any costs in connection with the construction or demolition of any improvements in the Premises (except as provided above with respect to the Sixth Amendment Construction Allowance).  The foregoing shall not limit or waive Landlord’s express obligations under the Lease with respect to the Premises, the Building or the Complex.  
7.    Chad Haskell (phone no.__________, email ____________) shall be Tenant’s Construction Representative, and shall have full power and authority to act on behalf of Tenant on any matters relating to the Landlord Work or Tenant’s Sixth Amendment Tenant Alterations.  Tenant may name a replacement Tenant Construction Representative from time to time by written notice to Landlord making reference to this Section 7.  _____ (phone no. __________, email ______________) shall be Landlord’s Construction Representative, shall have full power and authority to act on behalf of Landlord on any matters relating to the Landlord Work or Tenant’s Sixth Amendment Tenant Alterations.  Landlord may name a replacement Landlord Construction Representative from time to time by written notice to Tenant making reference to this Section 7. 
8.    All disputes between the parties regarding Tenant SA Delays and other matters expressly referencing this Section 8 shall be resolved in accordance with this Section 8.  Any arbitration decision under this Section 8 shall be enforceable in accordance with applicable law in any court of proper jurisdiction.  A party may not initiate arbitration under this Section 8 without notifying the other party and requesting a meeting of senior representatives to resolve the dispute.  Within five (5) business days following such notice, senior representatives of Landlord and Tenant who have authority to resolve the dispute shall meet in order to seek a resolution by agreement prior to the arbitration.  If the dispute is not so resolved at the meeting (or if one party does not attend) then either party may initiate arbitration. 
Any arbitration conducted pursuant to this Section 8 shall be conducted in as expeditious a manner as possible to avoid delays in the construction of the Landlord’s Work and the Sixth Amendment 


D-5
EAST\141300457.11 


 



Tenant Alterations and shall be resolved by a single arbitrator, who shall be agreed to by the parties within ten (10) days after either party requests arbitration under this Section 8 by notice to the other.  Landlord and Tenant shall seek to agree upon a single arbitrator who is an independent third party real estate professional with at least twenty (20) years of experience in construction disputes involving multi-tenant, first-class office developments that has not worked for either party for the prior five (5) years (a “Qualified Arbitrator”) and, if they are unable to agree, then a Qualified Arbitrator shall, upon request by either party, be appointed by the  office of the American Arbitration Association (“AAA”) or successor organization administering arbitrations held in Boston, Massachusetts.  The arbitrator shall decide the dispute by written decision.  The arbitration shall be conducted in Boston Massachusetts or another location agreed to by the parties in accordance with the Fast Track Procedures (regardless of the amount in dispute) of the Construction Industry Arbitration Rules of the AAA (or any successor organization), as modified and/or supplemented by this Section on an expedited basis and shall be concluded, with a decision issued, no later than thirty (30) days after the date that such dispute is submitted for arbitration.  The decision of the arbitrator shall be final and binding on the parties.  The parties shall comply with any orders of the arbitrator establishing deadlines for any such proceeding.  The fee of the arbitrator shall be paid equally by the parties.  Each party shall pay all other costs incurred by it in connection with the arbitration.
9.    This Work Letter shall not be deemed applicable to any additional space added to the Premises at any time following the execution of the Sixth Amendment or from time to time, whether by any options under the Lease or otherwise, or to any portion of the Premises or any additions to the Premises in the event of a renewal or extension of the Lease Term subsequent to the Sixth Amendment, whether by any options under the Lease or otherwise, unless expressly so provided in the Lease or any amendment or supplement to the Lease.  All capitalized terms used in this Work Letter but not defined herein shall have the same meanings ascribed to such terms in the Sixth Amendment, or if none, the Lease.
