 7. RENTABLE AREA 
  
 Total Rentable Area of the Premises and the Building shall be deemed to be as set forth in Exhibit 1. 
  
 8. SERVICES FURNISHED BY LANDLORD 
  
 8.1 Electric Current. 
  
 (a) As stated in Exhibit 1, Landlord will furnish to Tenant, as an incident
of this Lease. on a sub-metered basis, electric current for the operation of lighting fixtures, and the 120-volt electrical outlets initially installed in the premises and additional outlets installed by Tenant with Landlord’s consent, which
consent shall not be unreasonably withheld, for the operation of Tenant’s normal office fixtures and equipment, but excluding any high energy consumption equipment. or Landlord will require Tenant to contract with the company supplying electric
current for the purchase and obtaining by Tenant of electric current directly from such company to be billed directly to, and paid for by, Tenant. 
  
 (b) Tenant shall pay to Landlord, as additional rent, the cost of the electricity consumed on the premises during the term of this Lease as shown on such
sub-meter based upon the Electric Rate and Base Electric Cost, which Electric Rate and Base Electric Cost shall be equal to the actual amounts charged to Landlord by the utility company. The term “Base Electric Cost” as used in this Lease,
shall be defined as the composite, effective cost per annum, as of the Execution Date, of electric current per square foot of Building Total Rentable Area (as defined in Exhibit 1) for those portions of the Building as to which Landlord is providing
electric current. “Electric Rate,” as used in this Lease, shall be defined as the composite effective rate per kilowatt-hour taking into account the base utility rate, fuel adjustment factor, premium charges or credits for hours of use,
and any other charges which Landlord is required to pay in connection with furnishing electricity to the Building. The parties acknowledge that the consumption of electricity in the premises (other than electricity consumed for the purposes of
providing the services which Landlord is required to provide hereunder) will be measured by a separate sub-meter to be installed by Landlord. Tenant shall reimburse Landlord for the entire cost of such electric current as follows: 
  
 1. Commencing as of the Term Commencement Date and
continuing until the procedures set forth in Paragraph 2 of this Article S.l(c) are effected, Tenant shall pay to Landlord at the same time and in the same manner that it pays its monthly payments of Yearly Rent hereunder, estimated monthly payments
on account of Tenant’s obligation to reimburse Landlord for electricity consumed in the premises. Said estimated monthly payments are based upon the current Base Electric Cost and Electric Rate set forth on Exhibit 1. The Initial Estimated
Monthly Electric Payment is set forth on Exhibit 1. 
  
 2. Periodically after the Term Commencement Date, Landlord shall determine the actual cost of electricity consumed by Tenant in the premises (i.e. by reading Tenant’s sub-meter and by applying the actual Electric Rate(s) applicable to
the preceding period). If the total of Tenant’s estimated monthly payments on account of such period is less than the actual cost of electricity consumed in the premises during such period, Tenant shall pay the difference to Landlord when
billed therefor. If the total of Tenant’s estimated monthly payments on account of such period is greater than the actual cost of electricity consumed in the premises during such period, Tenant may credit the difference against its next
installment of rental or other charges due hereunder. 
  
 3. After each adjustment, as set forth in Paragraph 2 above, the amount of estimated monthly payments on account of Tenant’s obligation to reimburse Landlord for electricity in the premises shall be adjusted based upon the actual cost
of electricity consumed during the immediately preceding period. 
  
 (c) Landlord, at any time, at its option and upon not less than thirty (30) days’ prior written notice to Tenant, may discontinue such furnishing of electric current to the premises; and in such case Tenant shall contract with the
company supplying electric 

  

 6 

 
current for the purchase and obtaining by Tenant of electric current directly from such company. In the event Tenant itself contracts for electricity with
the supplier, either initially or pursuant to Landlord’s option as above stated, Landlord shall (i) permit its risers, conduits and feeders to the extent available, suitable and safely capable, to be used for the purpose of enabling Tenant
to purchase and obtain electric current directly from such company. (ii) without cost or charge to Tenant, make such alterations and additions to the electrical equipment and/or appliances in the Building as such company shall specify for the
purpose of enabling Tenant to purchase and obtain electric current directly from such company, and (iii) at Landlord’s expense, furnish and install in or near the premises any necessary metering equipment used in connection with measuring
Tenant’s consumption of electric current and Tenant, at Tenant’s expense, shall maintain and keep in repair such metering equipment. In the event that Landlord shall exercise the option set forth in this Subparagraph 8.l(e), then
(i) if Landlord is furnishing Tenant electric current on an additional rent basis, Tenant shall have no further obligation to pay Electricity Rent to Landlord after the date Landlord discontinues such furnishing of electric current or
(ii) if Landlord is furnishing Tenant electric current on a sub-metered basis, Tenant shall have no further obligation to make any Estimated Monthly Electric Payments after the date Landlord discontinues such furnishing of electric current.

  
 (d) Whether or not Landlord is furnishing electric current to
Tenant, if Tenant shall require electric current for use in the premises in excess of such reasonable quantity to be furnished for such use as hereinabove provided and if (i) in Landlord’s reasonable judgment, Landlord’s facilities
are inadequate for such excess requirements or (ii) such excess use shall result in an additional burden on the Building air conditioning system and additional cost to Landlord on account thereof then, as the case may be, (x) Landlord upon
written request and at the sole cost and expense of Tenant, will furnish and install such additional wire, conduits, feeders, switchboards and appurtenances as reasonably may be required to supply such additional requirements of Tenant if current
therefor be available to Landlord, provided that the same shall be permitted by applicable laws and insurance regulations and shall not cause damage to the Building or the premises or cause or create a dangerous or hazardous condition or entail
excessive or unreasonable alterations or repairs or interfere with or disturb other tenants or occupants of the Building or (y) Tenant shall reimburse Landlord for such additional cost, as aforesaid. 
  
 (e) Landlord, upon Tenant’s request, shall purchase and install all
replacement lamps of types generally commercially available (including, but not limited to, incandescent and fluorescent) used in the premises. 
  
 (f) Subject to Article 8.8, Landlord shall not in any way be liable or responsible to Tenant for any loss, damage or expense which Tenant may sustain or
incur if the quantity, character, or supply of electrical energy is changed or is no longer available or suitable for Tenant’s requirements. 
  
 (g) Tenant agrees that it will not make any material alteration or material addition to the electrical equipment and/or appliances in the premises which
would have an adverse effect on the Building’s systems without the prior written consent of Landlord in each instance first obtained, which consent will not be unreasonably withheld, and will promptly advise Landlord of any other alteration or
addition to such electrical equipment and/or appliances. 
  
 (h)
Any equipment shown on Tenant’s final approved plans and any equipment substituted therefor which has equivalent electrical requirements shall, provided that Tenant maintains such equipment in good operating order, not be deemed to require
electric current in excess of the reasonable quantity to be furnished for Tenant’s use as hereinabove provided. 
  
 8.2 Water. Landlord shall furnish hot and cold water for ordinary premises, cleaning, toilet, lavatory and drinking purposes. If Tenant requires, uses or
consumes water for any purpose other than for the aforementioned purposes, Landlord may (i) assess a reasonable charge for the additional water so used or consumed by Tenant or (ii) install a water meter and thereby measure Tenant’s
water consumption for all purposes. In the latter event, Landlord shall pay the cost of the meter and the cost of installation thereof and shall keep said meter and installation equipment in 

  

 7 

 
good working order and repair. Tenant agrees to pay for water consumed, as shown on said meter, together with the sewer charge based on said meter charges,
as and when bills are rendered, and on default in making such payment Landlord may pay such charges and collect the same from Tenant. All piping and other equipment and facilities for use of water outside the building core will be installed and
maintained by Landlord at Tenant’s sole cost and expense. 
  
 8.3 Elevators, Heat, Cleaning, Lighting. 
  
 (a)
Landlord at its expense shall: (i) provide necessary elevator facilities (which may be manually or automatically operated, either or both, as Landlord may from time to time elect) on Mondays through Fridays, excepting legal holidays, (as
defined on Exhibit 8), from 8:00 a.m. to 6:00 p.m. and on Saturdays, excepting legal holidays, from 8:00 a.m. to 1:00 p.m. (called “business days”) and have one elevator in operation available for Tenant’s use, non-exclusively,
together with others having business in the Building, at all other times; (ii) furnish heat (substantially equivalent to that being furnished in comparably aged similarly equipped office buildings in the same city) to the premises during the
normal heating season on business days to maintain a temperature of 68 degrees Fahrenheit dry bulb with outside conditions of 3 degrees Fahrenheit dry bulb; (iii) cause the office areas of the premises to be cleaned on business days (except on
Saturdays) provided the same are kept in order by Tenant; (iv) provide emergency lighting in the common areas of the Building as and to the extent required by applicable law; (v) provide lighting in the common areas of the Building and in
the parking areas as necessary, and (vi) provide venting in the common restrooms of the Building on business days. Either Exhibit 4 (if annexed hereto) or, otherwise, the cleaning standards generally prevailing in first-class office buildings
in the city or town where the Building is located, shall represent substantially the extent and scope of the cleaning by Landlord referred to in this Article 8.3. 
  
 (b) The parties agree and acknowledge that, despite reasonable precautions in selecting cleaning and maintenance contractors
and personnel, any property or equipment in the premises of a delicate, fragile or vulnerable nature may nevertheless be damaged in the course of cleaning and maintenance services being performed. Accordingly, Tenant shall take reasonable protective
precautions with such property and equipment (including, without limitation, computers or other data processing components or equipment and optical or electronic equipment, etc.), e.g., housing the property and equipment in a separate, locked room,
so as to render it inaccessible to the Building’s cleaning personnel. 
  
 8.4 Air Conditioning. Landlord shall through the air conditioning equipment of the Building furnish to and distribute in the premises and the common areas of the Building air conditioning as normal seasonal changes
may require on business days during the hours as aforesaid in Article 8.3 when air conditioning may reasonably be required for the comfortable occupancy of the premises by Tenant. Tenant agrees to lower and close the blinds or drapes when necessary
because of the sun’s position, whenever the air conditioning system is in operation, 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 system. The air conditioning system referred to in this Article 8.4 shall be capable of providing 78’ F dry bulb and 50% relative humidity with outside conditions of 92’ F dry bulb
and 74’ F wet bulb. The foregoing design conditions shall be based upon an occupancy within each separately partitioned area in the premises of not more than one person per 100 square feet of Total Rentable Area and upon a combined lighting and
standard electrical load not to exceed 2 1/2 watts per square foot of Total Rentable Area. 
  
 8.5 Additional Heat, Ventilating and Cleaning Services. 
  
 (a) Landlord will use reasonable efforts upon reasonable advance written
notice from Tenant of its requirements in that regard, to furnish additional heat, ventilating or cleaning services to the premises on days and at times other than as above provided. 
  
 (b) Tenant will pay to Landlord a reasonable charge (i) for any such additional heat, ventilating or cleaning service
required by Tenant. (ii) for any extra cleaning of the premises required because of the carelessness or indifference of Tenant or because of Tenant’s Weekly Receptions, as defined in Article 5.1, and (iii) for any cleaning done at the
request of Tenant of any portions of the premises which may be used for storage, 

  

 8 

 
shipping room or other non-office purposes. If the cost to Landlord for cleaning the premises shall be increased due to the installation in the premises, at
Tenant’s request, of any materials or finish other than those which are building standard, Tenant shall pay to Landlord an amount equal to such increase in cost. The charge for additional heating and ventilating shall be equal to the actual
cost of providing such service, including overhead and depreciation, but excluding profit, which charge, as of the Execution Date of this Lease, is equal to $40.75 per hour. Said charge shall only be increased in relation to the increase in actual
costs incurred by Landlord in providing such heating, ventilating and air conditioning service. 
  
 8.6 Additional Air Conditioning Equipment. In the event Tenant requires additional air conditioning for business machines, meeting rooms or other special
purposes, or because of occupancy or excess electrical loads, any additional air conditioning units, chillers, condensers, compressors, ducts, piping and other equipment, such additional air conditioning equipment will be installed and maintained by
Landlord at Tenant’s sole cost and expense, but only if, in Landlord’s reasonable judgment, the same will not cause damage or injury to the Building or create a dangerous or hazardous condition or entail excessive or unreasonable
alterations, repairs or expense or interfere with or disturb other tenants; and Tenant shall reimburse Landlord in such an amount as will compensate it for the cost incurred by it in operating such additional air conditioning equipment. Any
additional air conditioning equipment shown on Tenant’s final approved plans and any equipment substituted therefor which has equivalent electrical requirements shall, provided that Tenant maintains such equipment in good operating order, not
be deemed to violate the provisions of this Article 8.6. 
  
 8.7
Repairs. Except as otherwise provided in Articles 18 and 20, and subject to Tenant’s obligations in Article 14, Landlord shall keep and maintain the roof, exterior walls, structural floor slabs, columns, elevators, public stairways and
corridors, lavatories, equipment (including, without limitation, sanitary, electrical, heating, air conditioning, or other systems) and other common facilities of the Building, including the parking areas thereof, in good condition and repair.

  
 8.8 Interruption or Curtailment of Services. 
  
 A. When necessary by reason of accident or emergency, or for repairs,
alterations, replacements or improvements which in the reasonable judgment of Landlord are necessary to be made, or of inability in securing supplies or labor, or of strikes, or of any other cause beyond the reasonable control of Landlord, whether
such other cause be similar or dissimilar to those hereinabove specifically mentioned until said cause has been removed, Landlord reserves the right to interrupt, curtail, stop or suspend (i) the furnishing of heating, elevator, air
conditioning, and cleaning services and (ii) the operation of the plumbing and electric systems. Landlord shall exercise reasonable diligence to eliminate the cause of any such interruption, curtailment, stoppage or suspension, but there shall
be no diminution or abatement of rent or other compensation due from Landlord to Tenant hereunder, 
  
 B. Notwithstanding anything to the contrary in this Lease contained, if the premises shall lack any service which Landlord is required to provide
hereunder (thereby rendering the premises or a portion thereof untenantable) so that, for the Landlord Service Interruption Cure Period, as hereinafter defined, the continued operation in the ordinary course of Tenant’s business is materially
adversely affected and if Tenant ceases to use the affected portion of the premises during the period of untenantability as the direct result of such lack of service, then, provided that Tenant ceases to use the affected portion of the premises
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 Tenant or Tenant’s agents, employees or
contractors, Yearly Rent, Operating Expense Excess and Tax Excess shall thereafter be abated in proportion to such untenantability until the day such condition is completely corrected. 
  
 For the purposes hereof, the “Landlord Service interruption Cure Period” shall be defined as five ( 5 )
consecutive business days after Landlord’s receipt of written notice from Tenant of the condition causing untenantability in the premises, provided however, that the Landlord Service Interruption Cure Period shall be ten (10) consecutive
business days 

  

 9 

 
after Landlord’s receipt of written notice from Tenant of such condition causing untenantability in the premises if either the condition was caused by
causes beyond Landlord’s control or Landlord is unable to cure such condition as the result of causes beyond Landlord’s control. 
  
 C. Notwithstanding anything to the contrary in this Lease contained, in the event that the premises lack any service which Landlord is required to provide
hereunder or electric current thereby rendering the premises or any material portion thereof untenantable, the untenantability of which substantially adversely affects the continued operation in the ordinary course of Tenant’s business, and
(i) if such untenantability continues for ninety (90) consecutive days after Landlord’s receipt of written notice of such condition from Tenant, and (ii) such untenantability is not caused by the fault or neglect of Tenant, or
Tenant’s agents, employees, or contractors, then, provided that Tenant ceases to use the affected portion of the premises during the entire period of such untenantability, Tenant shall have the right to terminate this Lease exercisable by
giving Landlord a written termination notice as follows. This Lease shall terminate as of the date ten (10) days after Landlord’s receipt of Tenant’s notice, unless Landlord shall have cured such condition on or before such tenth day.

  
 D. The provisions of Paragraphs B and C of this Article 8.8
shall not apply in the event of untenantability caused by fire or other insured casualty, or taking (see Articles 18 and 20). 
  
 8.9 Energy Conservation. Notwithstanding anything to the contrary in this Article 8 or in this Lease contained, Landlord may institute, and Tenant shall
comply with, such policies, programs and measures as may be necessary, required, or expedient for the conservation and/or preservation of energy or energy services, or as may be necessary or required to comply with applicable codes, rules
regulations or standards. 
  
 8.10 Miscellaneous. Other than air
conditioning, all services provided by Landlord to Tenant are based upon an assumed maximum premises population of one person per two hundred (200) square feet of Total Rentable Area (“Limit”), which Limit Tenant shall in no event
exceed. Notwithstanding anything to the contrary in the Lease contained, the parties hereby acknowledge that within the classrooms of the premises, Tenant will be exceeding the Limit. Landlord shall permit Tenant to exceed the Limit in the
classrooms, provided that (i) Tenant keeps such classrooms reasonably clean (i.e., putting cups, cans, paper, etc. in wastebaskets) and (ii) Tenant’s use of the classrooms complies with all applicable zoning and other legal
requirements.

Capital Expenditures. 
  
 (i) New Capital Items. If a new
capital item is acquired which does not replace another capital item which was worn out, has become obsolete, etc., and such new capital item is either required by law or reasonably estimated to reduce Operating Costs, then there shall be included
in Operating Costs for each Operating Year in which and after such capital expenditure is made the Annual Charge-Off of such capital expenditure. 
  
 (ii) Annual Charge-Off. “Annual Charge-Off” shall be defined as the annual amount of principal and interest payments which would be required to
repay a loan (“Capital Loan”) in equal monthly installments over the Useful Life, as hereinafter defined, of the capital item in question on a direct reduction basis at an annual interest rate equal to the Capital Interest Rate, as
hereinafter defined, where the initial principal balance is the cost of the capital item in question. Notwithstanding the foregoing, if Landlord reasonably concludes on the basis of engineering estimates that a particular capital expenditure will
effect savings in Building operating expenses including, without limitation, energy related costs, and that such projected savings will, on an annual basis (“Projected Annual Savings”), exceed the Annual Charge-Off of such capital
expenditure computed as aforesaid, then and in such events, the Annual Charge-Off shall be increased to an amount equal to the Projected Annual Savings; and in such circumstances, the increased Annual Charge-Off (in the amount of the Projected
Annual Savings) shall be made for such period of time as it would take to fully amortize the cost of the capital item in question, together with interest thereon at the Capital Interest Rate as aforesaid, in equal monthly payments, each in the
amount of one-twelfth (1/12th) of the Projected Annual Savings, with such payments being applied first to interest and the balance to principal. 
  
 (iii) Useful Life. “Useful Life” shall be reasonably determined by Landlord in accordance with generally accepted accounting principles and
practices in effect at the time of acquisition of the capital item. 
  

 12 

 (iv) Capital interest Rate. “Capital Interest Rate” shall be defined as an annual rate of
either one percentage point over the AA Bond rate (Standard & Poor’s corporate composite or, if unavailable, its equivalent) as reported in the financial press at the time the capital expenditure is made or. If the capital item is
acquired through third-party financing, then the actual (including fluctuating) rate paid by Landlord in financing the acquisition of such capital item. 
  
 (4) Specifically Included Categories of Operating Costs. 
  
 Operating Costs shall include, but not be limited to, the following: 
 Taxes (other than real estate taxes): Sales, Federal Social Security, Unemployment and Old Age Taxes and contributions and State Unemployment taxes and contributions accruing to and paid by the Landlord on account of
all employees of Landlord and/or Landlord’s managing agent, who are employed in, about or on account of the Building, except that taxes levied upon the net income of the Landlord and taxes withheld from employees, and “Taxes” as
defined in Article 9.l(d) shall not be included herein, provided however, that with respect to any employee who performs services for buildings other than the Building, the taxes payable or allocable to such employee shall be equitably apportioned
among the buildings to which such employee, renders services based upon the time which such employee spent performing services for each such building.

allocable to such employee shall be equitably apportioned among the buildings to which such employee renders services based upon the time which such employee spent performing services for each such building. 
  
 Cleaning: The cost of labor and material for cleaning the Building,
surrounding areaways and windows in the Building. 
  
 Elevator
Maintenance: All expenses for or on account of the upkeep and maintenance of all elevators in the Building.

buildings in the City or Town wherein the Building is located and all other expenses customarily incurred in connection with the operation and maintenance of first-class office buildings in the City or Town wherein the Building is located including,
without limitation, a management fee payable by Landlord and rental costs associated with the Park’s management office. Such rental costs shall be equitably apportioned among the buildings in the Park owned by Landlord. 
  
 9.2 Tax Excess. If in any Tax Period the Taxes exceed the Tax Base, Tenant
shall pay to Landlord Tenant’s Proportionate Share of such excess, such amount being hereinafter referred to as “Tax Excess”. Tax Excess shall be due when billed by Landlord. In implementation and not in limitation of the foregoing,
Tenant shall remit to Landlord pro rata monthly installments on account of projected Tax Excess, calculated by Landlord on the basis of the most recent Tax data 

  

 13 

 
available. If the total of such monthly remittances on account of any Tax Period is greater than the actual Tax Excess for such Tax Period, Tenant may credit
the difference against the next installment of rental or other charges due to Landlord hereunder. If the total of such remittances is less than the actual Tax Excess for such Tax Period, Tenant shall pay the difference to Landlord when billed
therefor. 
  
 Appropriate credit against Tax Excess 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. The original computations, as well as reimbursement or payments of additional charges,
if any, or allowances, if any, under the provisions of this Article 9.2 shall be based on the original assessed valuations with adjustments to be made at a later date when the tax refund, if any, shall be paid to Landlord by the taxing authorities.
Expenditures for legal fees and for other similar or dissimilar expenses incurred in obtaining the tax refund may be charged against the tax refund before the adjustments are made for the Tax Period. 
  
 9.3 Operating Expense Excess. If the Operating Costs in any Operating Year
exceed the Operating Costs in the Base Year, Tenant shall pay to Landlord Tenant’s Proportionate Share of such excess, such amount being hereinafter referred to as “Operating Expense Excess.” Operating Expense Excess shall be due when
billed by Landlord. In implementation and not in limitation of the foregoing, Tenant shall remit to Landlord pro rata monthly installments on account of projected Operating Expense Excess, calculated by Landlord on the basis of the most recent
Operating Costs data or budget available. If the total of such monthly remittances on account of any Operating Year is greater than the actual Operating Expense Excess for such Operating Year, Tenant may credit the difference against the next
installment of rent or other charges due to Landlord hereunder. If the total of such remittances is less than actual Operating Expense Excess for such Operating Year, Tenant shall pay the difference to Landlord when billed therefor. 
  
 9.4 Part Years. If the Term Commencement Date or the Termination Date occurs
in the middle of an Operating Year or Tax Period, Tenant shall be liable for only that portion of the Operating Expense or Tax Excess, as the case may be, in respect of such Operating Year or Tax Period represented by a fraction the numerator of
which is the number of days of the herein term which falls within the Operating Year or Tax Period and the denominator of which is three hundred sixty-five (365), or the number of days in said Tax Period, as the case may be. 
  
 9.5 Effect of Taking. In the event of any taking of the Building or the land
upon which it stands under circumstances whereby this Lease shall not terminate under the provisions of Article 20 then, for the purposes of determining Tax Excess, there shall be substituted for the Tax Base originally provided for herein a
fraction of such Tax Base, the numerator of which fraction shall be the Taxes for the first Tax Period subsequent to the condemnation or taking which takes into account such condemnation or taking, and the denominator of which shall be the Taxes for
the last Tax Period prior to the condemnation or taking, which did not take into account such condemnation or taking. Tenant’s Proportionate Share shall be adjusted appropriately to reflect the proportion of the premises and/or the Building
remaining after such taking. 
  
 9.6 Disputes, etc. Any disputes
arising under this Article 9 may, at the election of either party, be submitted to arbitration as hereinafter provided. Any obligations under this Article 9 which shall not have been paid at the expiration or sooner termination of the term of this
Lease shall survive such expiration and shall be paid when and as the amount of same shall be determined to be due. 
  
 10. CHANGES OR ALTERATIONS BY LANDLORD

Building (including the premises) and the fixtures and equipment thereof, (ii) the street entrances, halls, passages, elevators, escalators, and stairways of the Building, as it may deem necessary or desirable, and (iii) the arrangement

liability of Tenant with respect to making any repair, replacement or improvement or complying with any law, order or requirement of any governmental or other authority. Landlord reserves the right to adopt and at any time and from time to time to
change the name or address of the Building. Neither this Lease nor any use by Tenant shall give Tenant any right or easement for the use of any door or any passage or any concourse connecting with any other building or to any public convenience, and

in respect of the Recapture Premises (in the case of a proposed assignment of Tenant’s interest in the Lease or a subletting for the remainder of the term of the Lease) or to suspend the term of the Lease pro tanto in respect of the Recapture
Period (i.e. the term of the Lease in respect of the Recapture Premises shall be terminated during the Recapture Period and Tenant’s rental obligations shall be reduced in proportion to the ratio of the Total Rentable Area of the Recapture
Premises to the Total Rentable Area of the premises then demised to Tenant). 
  
 3. Landlord shall have thirty (30) days to accept a Recapture Offer. If Landlord does not timely give written notice to Tenant accepting a Recapture Offer, then Landlord agrees that it will not unreasonably
withhold or delay its consent to a sublease of the Recapture Premises for the Recapture Period, or an assignment of Tenant’s interest in the Lease, as the case may be, to a Qualified Transferee, as hereinafter defined. 
  
 4. For the purposes hereof, a “Qualified Transferee” shall be
defined as a person, firm or corporation which, in Landlord’s reasonable opinion: 
  
 (a) is financially responsible and of good reputation; 
  
 (b) is engaged in a business, the functional aspects of which, with respect to the premises, are similar to the use of other premises made by other office space tenants in the Building; and 
  
 (c) is not a Restricted Park Occupant, as hereinafter defined. 

 
 5. For the purposes hereof, a “Restricted Park Occupant” shall
be defined as any tenant or subtenant of premises in the Park (“Park Occupant”). Notwithstanding the foregoing, a Park Occupant who satisfies all three of the following criteria shall not be deemed to be a Restricted Park Occupant:

  
 (a) Such occupant desires to sublease the Recapture Premises
for expansion purposes only; and 
  
 (b) Such Occupant’s
occupancy of the Recapture Premises will not, either directly or indirectly, cause a vacancy in the premises which such occupant then occupies in the Park; and 
  

(c) Such Occupant’s need, as to the size of premises and length of term, cannot then (i.e., at the time that Tenant requests Landlord’s
consent to such Occupant) be satisfied by Landlord. 
  
 6.
Notwithstanding anything to the contrary in this Paragraph B contained: 
  
 (a) If Tenant is in default of its obligations under the Lease at the time that it makes the aforesaid offer to Landlord, such default shall be deemed to be a “reasonable” reason for Landlord withholding its
consent to any proposed subletting or assignment: and 
  
 (b) If
Tenant does not enter into a sublease with a subtenant (or an assignment to an assignee, as the case may be) approved by Landlord, as aforesaid, on or before the date which is one hundred eighty (180) days after the earlier of: (x) the
expiration of said thirty (30) day period, or (y) the date that Landlord notifies Tenant that Landlord will not accept Tenant’s offer to terminate or suspend the Lease, then Landlord shall have the right arbitrarily to withhold its
consent to any subletting or assignment proposed to be entered into by , Tenant after the expiration of said one hundred eighty (180) day period unless Tenant again offers, in accordance with this Paragraph B, either to terminate or to suspend
the Lease in respect of the portion of the premises proposed to be sublet (or in respect of the entirety of the premises in the event of a proposed assignment, as the case may be). If Tenant shall make any subsequent offers to terminate or 

  

 20 

 
suspend the Lease pursuant to this Paragraph B, any such subsequent offers shall be treated in all respects as if it is Tenant’s first offer to suspend
or terminate the Lease pursuant to this Paragraph B. 
  
 7.
Notwithstanding anything to the contrary herein contained, but subject to the last sentence of this Subparagraph 7, Tenant shall have no rights with respect to either Portion of the premises under this Paragraph B hereof prior to the date one
(1) year after the Rent Commencement Date in respect of such Portion of the premises. Without limiting the foregoing, Tenant shall have no right to give Landlord a Recapture Offer with respect to either Portion of the Premises prior to the date
one (1) year after the Rent Commencement Date in respect of such Portion of the premises. Notwithstanding anything to the contrary in this Subparagraph 7 contained, in the event that Tenant is not allowed to use the premises for the Permitted
Use due to applicable laws, codes, orders, rules or regulations prior to the date one (1) year after the Rent Commencement Date, then Tenant shall have its rights under this Paragraph B prior to the date one (1) year after the Rent
Commencement Date in respect of such Portion of the premises. 
  
 8. No subletting or assignment shall relieve Tenant of its primary obligation as party-Tenant hereunder, nor shall it reduce or increase Landlord’s obligations under the Lease. 
  
 C. Notwithstanding anything to the contrary herein contained, Tenant shall
have the right, without obtaining Landlord’s consent and without giving Landlord a Recapture Offer, to assign its interest in this Lease and to sublease the premises, or any portion thereof, to an Affiliated Entity, as hereinafter defined, so
long as such entity remains in such relationship to Tenant, and provided that prior to or simultaneously with such assignment or sublease, such Affiliated Entity executes and delivers to Landlord an Assumption agreement, as hereinabove defined. For
the purposes hereof, an “Affiliated Entity” shall be defined as any entity which is controlled by, is under common control with, or which controls Tenant. For the purposes hereof, control shall mean the direct or indirect ownership of more
than fifty (50%) percent of the beneficial interest of the entity in question. 
  
 D. If Tenant is an individual who uses and/or occupies the premises with partners, or if Tenant is a partnership, then: 
  
 (i) Each present and future partner shall be personally bound by and upon all of the covenants, agreements. terms, provisions and conditions set forth in
this Lease on the part of Tenant to be performed; and 
  
 (ii) In
confirmation of the foregoing, Landlord may (but without being required to do so) request (and Tenant shall duly comply) that Tenant, at the time that Tenant admits any new partner to its partnership, shall require each such new partner to execute
an agreement in form and substance satisfactory to Landlord whereby such new partner shall agree to be personally bound by and upon all of the covenants, agreements, terms, provisions and conditions of this Lease on the part of Tenant to be
performed, without regard to the time when such new partner is admitted to partnership or when any obligations under any such covenants, etc., accrue. 
  
 E. 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. 
  
 F. If
this Lease be assigned, or if the premises or any part thereof be sublet or occupied by anybody other than Tenant, Landlord may, at any time and from time to time, collect rent and other charges from the assignee, subtenant or occupant, and apply
the net amount collected to the rent and other charges herein reserved then due and thereafter becoming due, but no such assignment, subletting, occupancy or collection shall be deemed a waiver of this covenant, or the acceptance of the assignee,
subtenant or occupant as a tenant, or a release of Tenant from the further performance by Tenant of covenants on the part of Tenant herein contained. Any consent by Landlord to a particular assignment or subletting shall not in any way diminish the
prohibition stated in the first sentence of this Article 16 or the continuing liability of the Tenant named on 

  

 21 

 
Exhibit 1 as the party Tenant under this Lease. No assignment or subletting shall affect the purpose for which the premises may be used as stated in Exhibit
1.

agent is liable therefor (if during such entry Landlord or Landlord’s agents shall accord reasonable care to Tenant’s property), and without in any manner affecting the obligations and covenants of this Lease. 
  
 Provided that Landlord shall incur no additional expense thereby, Landlord

 18.
DAMAGE BY FIRE, ETC. 
  
 During the entire term of this
Lease, and adjusting insurance coverages to reflect current values from time to time:—(i) Landlord shall keep the Building (excluding work, installations, improvements and betterments in the premises which exceed the specifications provided in
Exhibit 3, [called “Over-Building-Standard Property”] and any other property installed by or at the expense of Tenant) insured against loss or damage caused by any peril covered under fire, extended coverage and all risk insurance in an
amount equal to one hundred percent (1 00%) of the full insurable value thereof above foundation walls; and (ii) Tenant shall keep its personal property in and about the premises and the Over-Building-Standard Property insured against loss or
damage caused by any peril covered under fire, extended coverage and all risk insurance in an amount equal to one hundred percent (1 00%) of the full insurable value thereof. Such Tenant’s insurance shall insure the interests of both Landlord
and Tenant as their respective interests may appear from time to time and shall name Landlord as an additional insured: and the proceeds thereof shall be used only for the replacement or restoration of such personal property and the
Over-Building-Standard Property. 
  
 If any portion of the
premises required to be insured by Landlord under the preceding paragraph shall be damaged by fire or other Insured casualty, Landlord shall proceed with diligence, subject to the then applicable statutes, building codes, zoning ordinances, and
regulations of any governmental authority, and at the expense of Landlord (but only to the extent of insurance proceeds made available to Landlord by any mortgagee and/or ground lessor of the real property of which the premises are a part) to repair
or cause to be repaired such damage, provided, however, in respect of any Over-Building Standard Property as shall have been damaged by such fire or other casualty and which (in the judgment of Landlord) can more effectively be repaired as an
Integral part of Landlord’s repair work on the premises, that such repairs to such Tenant’s alterations, decorations, additions and improvements shall be performed by Landlord but at I Tenant’s expense; in all other respects, all
repairs to and replacements of Tenant’s property and Over-Building-Standard Property shall be made by and at the expense of Tenant. If the premises or any part thereof shall have been rendered unfit for use and occupation hereunder by reason of
such damage the Yearly Rent or a just and proportionate part thereof, according to the nature and extent to which the premises shall have been so rendered unfit, shall be suspended or abated until the premises (except as to the property which is to
be repaired by or at the expense of Tenant) shall have been restored as nearly as practicably may be to the condition in which they were immediately prior to such fire or other casualty. Tenant agrees to cooperate with Landlord in such manner as
Landlord may reasonably request in assisting Landlord in collecting rent insurance proceeds due in connection with any casualty which affects the premises. Landlord shall not be liable for delays in the making of any such repairs which are due to
government regulation, casualties and strikes, unavailability of labor and materials, and other causes beyond the reasonable control of Landlord, nor shall Landlord be liable for any inconvenience or annoyance to Tenant or injury to the business of
Tenant resulting from delays in repairing such damage. If (i) the premises are so damaged by fire or other casualty (whether or not insured) at any time during the last eighteen (18) months of the term hereof that the cost to repair such
damage is reasonably estimated to exceed one third of the total Yearly Rent payable hereunder for the period from the estimated date of restoration until the Termination Date, or (ii) the Building (whether or not including any portion of the
premises) is so damaged by fire or other casualty (whether or not insured) that substantial alteration or reconstruction of fifty (50%) percent or more of the Building or demolition of the Building shall in Landlord’s judgment be required,
then and in either of such events, this Lease and the term hereof may be terminated at the election of Landlord by a notice in writing of its election so to terminate which shall be given by Landlord to Tenant within sixty (60) days following
such fire or other casualty, the effective termination date of which shall be not less than thirty (30) days after the day on which such termination notice is received by Tenant. Notwithstanding anything to the contrary herein contained,
Landlord shall not exercise its right to terminate the term of the Lease pursuant to clause (ii) of the immediately preceding sentence unless Landlord also terminates the leases of all other tenants similarly affected by such fire or 

  

 25 

 
casualty. in the event of any termination, this Lease and the term hereof shall expire as of such effective termination date as though that were the
Termination Date as stated in Exhibit 1 and the Yearly Rent shall be apportioned as of such date; and if the premises or any part thereof shall have been rendered unfit for use and occupation by reason of such damage the Yearly Rent for the period
from the date of the tire or other casualty to the effective termination date, or a just and proportionate part thereof, according to the nature and extent-to which the premises shall have been so rendered unfit, shall be abated. If any portion of
the premises or any portion of the Building shall be damaged or destroyed by fire or other casualty to the extent that the operation of Tenant’s business in the premises in the normal course is materially adversely affected, then, within thirty
(30) days of such fire or other casualty, Landlord shall submit to Tenant a reasonable engineering estimate as to the estimated length of time to complete such repairs. If the time period (“Estimated Restoration Period”) set forth in
such estimate shall exceed one hundred eighty (180) days of the date of such casualty. Tenant may elect, by a notice sent within fifteen (15) days after notice of such estimate is sent to Tenant. to terminate this Lease. If such estimate
shall fall within the 180-day limit, Tenant shall have no such right to terminate and Landlord shall, subject to the provisions of this Article 18, proceed with due diligence and promptness to reasonably complete the repairs or restoration within
such one hundred eighty (180) days, subject always to delays for causes beyond Landlord’s reasonable control including, but not limited to the causes specified in Article 26 hereof, and the other limitations set forth in this Article 18.

  
 In the event that the premises or the Building are damaged by
fire or other casualty to such an extent so as to render the premises untenantable, and if Landlord shall fail to substantially complete said repairs or restoration within a period (“Restoration Period”) which is the greater of the
Estimated Restoration Period or one hundred fifty (150) days after the date of such fire or other casualty for any reason other than Tenant’s fault, Tenant may terminate this Lease by giving Landlord written notice as follows: 

 
 (a) Said notice shall be given after said Restoration Period. 

 
 (b) Said notice shall set forth an effective date which is not earlier
than thirty (30) days after Landlord receives said notice. 
  
 (c) If said repairs or restoration are substantially complete on or before the date thirty (30) days (which thirty-(30)-day period shall be extended by the length of any delays caused by Tenant or Tenant’s contractors) after
Landlord receives such notice, said notice shall have no further force and effect. 
  
 (d) If said repairs or restoration are not substantially complete on or before the date thirty (30) days (which thirty-(30)-day period shall be extended by the length of any delays caused by Tenant or
Tenant’s contractors) after Landlord receives such notice, the Lease shall terminate as of said effective date. 
  
 19. WAIVER OF SUBROGATION 
  
 In any case in which Tenant shall be obligated to pay to Landlord any loss, cost, damage, liability, or expense suffered or incurred by Landlord, Landlord
shall allow to Tenant as an offset against the amount thereof (i) the net proceeds of any insurance collected by Landlord for or on account of such loss, cost, damage, liability or expense, provided that the allowance of such offset does not
invalidate or prejudice the policy or policies under which such proceeds were payable, and (ii) if such loss, cost, damage, liability or expense shall have been caused by a peril against which Landlord has agreed to procure insurance coverage
under the terms of this Lease, the amount of such insurance coverage, whether or not actually procured by Landlord. 
  
 In the event that neither Landlord nor Tenant elects to terminate this Lease pursuant to the first paragraph of this Article 20, then, within thirty
(30) days of such taking, appropriation or condemnation, Landlord shall submit to Tenant a reasonable engineering estimate as to the estimated length of time to complete such restoration. If the time period (“Estimated Restoration
Period”) set forth in such estimate shall exceed one hundred eighty (180) days of the date of such taking, appropriation or condemnation, Tenant may elect; by a notice sent within fifteen (15) days after notice of such estimate is
sent to Tenant, to terminate this Lease. If such estimate shall fall within the 180-day limit, Tenant shall have no such right to terminate and Landlord shall, subject to the provisions of this Article 20, proceed with due diligence and promptness
to restore the remainder of the premises, or the remainder of the means of access, as nearly as practicably may be to the same condition as obtained prior to such taking, appropriation or condemnation 

  

 26 

 
within such one hundred eighty (180) days, subject always to delays for causes beyond Landlord’s reasonable control including, but not limited to
the causes specified in Article 26 hereof, and the other limitations set forth in this Article 20. 
  
 In the event that Landlord does not elect to terminate this Lease and if Landlord shall fail to substantially complete said restoration within one hundred
fifty (150) days after the date of such taking or condemnation for any reason other than Tenant’s fault? Tenant may terminate this Lease by giving Landlord written notice as follows: 
  
 (a) Said notice shall be given after said one hundred fifty (150) day
period. 
  
 (b) Said notice shall set forth an effective date
which is not earlier than thirty (30) days after Landlord receives said notice. 
  
 (c) If said restoration is substantially complete on or before said effective date, said notice shall have no further force and effect. 
  
 (d) If said restoration is not substantially complete on or before said effective date for any reason other then
Tenant’s fault, the Lease shall terminate as of said effective date. 
  
 Except for any award specifically reimbursing Tenant for moving or relocation expenses, and any award specifically reimbursing Tenant for the taking of Tenant’s personal property or leasehold improvements,
provided that such award does not reduce any award payable to Landlord, there are expressly reserved to Landlord all rights to compensation and damages created, accrued or accruing by reason of any such taking, appropriation or condemnation, in
implementation and in confirmation of which Tenant does hereby acknowledge that Landlord shall be entitled to receive all such compensation and damages, grant to Landlord all and whatever rights (if any) Tenant may have to such compensation and
damages, and agree to execute and deliver all and whatever further instruments of assignment as Landlord may from time to time request. In the event of any taking of the premises or any part thereof for temporary (i.e., not in excess of one
(1) year) use, (i) this Lease shall be and remain unaffected thereby, and (ii) Tenant shall be entitled to receive for itself any award made to the extent allocable to the premises in respect of such taking on account of such use,
provided, that if any taking is for a period extending beyond the term of this Lease, such award shall be apportioned between Landlord and Tenant as of the Termination Date or earlier termination of this Lease.

shall not be revested in Tenant within thirty (30) days thereafter: or (g) a receiver, sequesterer. trustee or similar officer shall be appointed by a court of competent jurisdiction to take charge of all or any part of Tenant’s
property and such appointment shall not be vacated within thirty (-30) days; or (h) any proceeding shall be instituted 

  

 27 

 
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 (i) any event shall occur or any contingency shall arise whereby this Lease, or the term and estate thereby created, would (by operation of law or otherwise) devolve upon or pass to any person, firm or corporation other
than Tenant, except as expressly permitted under Article 16 hereof - then, and in any such event (except as hereinafter in Article 2 1.2 otherwise provided) Landlord may, by notice to Tenant, elect to terminate this Lease; and thereupon (and without
prejudice to any remedies which might otherwise be available for arrears of rent or other charges due hereunder or preceding breach of covenant or agreement and without prejudice to Tenant’s liability for damages as hereinafter stated), upon
the giving of such notice, this Lease shall terminate as of the date specified therein as though that were the Termination Date as stated in Exhibit 1. Without being taken or deemed to be guilty of any manner of - trespass or conversion. and without
being liable to indictment, prosecution or damages therefor, Landlord may, forcibly if necessary, enter into and upon the premises (or any part thereof in the name of the whole); repossess the same as of its former estate; and expel Tenant and those
claiming under Tenant. Wherever “Tenant “ is used in subdivisions (b), (c), (d), (e), (0(,g ) and (h) of this Article 2 1.1, it shall be deemed to include any one of (i) any corporation of which Tenant is a controlled subsidiary
and (ii) any guarantor of any of Tenant’s obligations under this Lease. The words “re-entry” and “re-enter” as used in this Lease are not restricted to their technical legal meanings. 
  
 21.2 Damages - Assignment for Benefit of Creditors. For the more effectual
securing to Landlord of the rent and other charges and payments reserved hereunder, it is agreed as a further condition of this Lease that if at any time Tenant shall make any transfer similar to or in the nature of an assignment of its property for
the benefit of its creditors, the term and estate hereby created shall terminate ipso facto, without entry or other action by Landlord; and notwithstanding any other provisions of this Lease, Landlord shall forthwith upon such termination, without
prejudice to any remedies which might otherwise be available for arrears of rent or other charges due hereunder or preceding breach of this Lease, be ipso facto entitled to recover as liquidated damages the sum of (a) the amount described in
clause (x) of Article 21.3 and (b) (in view of the uncertainty of prompt re-letting and the expense entailed in re-letting the premises) an amount equal to the rent and other charges payable for and in respect of the twelve-(12)-month
period next preceding the date of termination, as aforesaid. 
  
 21.3 Damages - Termination. Upon the termination of this Lease under the provisions of this Article 21, then except as hereinabove in Article 21.2 otherwise provided, Tenant shall pay to Landlord the rent and other charges payable by Tenant
to Landlord up to the time of such termination, shall continue to be liable for any preceding breach of covenant, and in addition, shall pay to Landlord as damages, at the election of Landlord either: 
  
 (x) the amount by which, at the time of the termination of this Lease (or at
any time thereafter if Landlord shall have initially elected damages under subparagraph (y), below), (i) the aggregate of the rent and other charges projected over the period commencing with such termination and ending on the Termination Date
as stated in Exhibit 1 exceeds (ii) the aggregate projected rental value of the premises for such period; 
  
 Or: 
  
 (y) amounts equal to the rent and other charges 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 Termination Date as specified in Exhibit 1, 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, it being understood
that any such re-letting may be for a period equal to or shorter or longer than the remaining term of this Lease; and provided, further, that (i) in no event shall Tenant be entitled to receive any excess of such net rents over the sums payable
by Tenant to 

  

 28 

 
Landlord hereunder and (ii) in no event shall Tenant be entitled in any suit for the collection of damages pursuant to this Subparagraph (y) 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. 
  
 In calculating the rent and other charges under Subparagraph (x), above, there shall be included, in addition to the Yearly Rent, Tax Excess and Operating
Expense Excess and all other considerations agreed to be paid or performed by Tenant, on the assumption that all such amounts and considerations would have remained constant (except as herein otherwise provided) for the balance of the full term
hereby granted. 
  
 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 of this Lease would have expired if it
had not been terminated hereunder. 
  
 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 default hereunder on the
part of Tenant. 
  
 21.4 Fees and Expenses. 
  
 (a) If Tenant shall default in the performance of any covenant on
Tenant’s part to be performed as in this Lease contained, Landlord may immediately, or at any time thereafter, without notice, perform the same for the account of Tenant. If Landlord at any time is compelled to pay or elects to pay any sum of
money, or do any act which will require the payment of any sum of money, by reason of the failure of Tenant to comply with any provision hereof, or if Landlord is compelled to or does incur any expense, including reasonable attorneys’ fees, in
instituting, prosecuting, and/or defending any action or proceeding instituted by reason of any default of Tenant hereunder, Tenant shall an demand pay to Landlord by way of reimbursement the sum or sums so paid by Landlord with all costs and
damages, plus interest computed as provided in Article 6 hereof. 
  
 (b) Tenant shall pay Landlord’s cost and expense, including reasonable attorneys’ fees, incurred (i) in enforcing any obligation of Tenant under this Lease or (ii) as a result of Landlord, without its fault, being made
party to any litigation pending by or against Tenant or any persons claiming through or under Tenant. 
  
 21.5 Waiver of Redemption. Tenant does hereby waive and surrender all rights and privileges which it might have under or by reason of any present or
future law 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. 
  
 21.6 Landlord’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. 
  
 21.7 Grace Period. Notwithstanding anything to the contrary in this Article contained, Landlord agrees not to take any action to terminate this Lease
(a) for default by Tenant in the payment when due of any sum of money, if Tenant shall cure such default within ten (10) days after written notice thereof is given by Landlord to Tenant, provided, however, that no such notice need be given
and no such default in the payment of money shall be curable if on two (2) prior occasions in the immediately preceding twelve-(12)-month period, there had been a default in the payment of money which had been cured after notice thereof had
been given by Landlord to Tenant as herein provided or (b) for default by Tenant in the performance of any covenant other than a covenant to pay a sum of money, if Tenant shall - cure such default within a period of thirty (30) days after
written notice thereof given by Landlord to Tenant (except where the nature of the default is such that remedial action should appropriately take place sooner, as indicated in such written notice), or within such additional period as may reasonably
be required to cure such default if (because of governmental restrictions or any other cause beyond the reasonable control 

  

 29 

 
of Tenant) the default is of such a nature that it cannot be cured within such thirty-(30)-day period, provided, however, (1) that there shall be no
extension of time beyond such thirty-(30)-day period for the curing of any such default unless, not more than ten (10) days after the receipt of the notice of default, Tenant in writing (i) shall specify the cause on account of which the
default cannot be cured during such period and shall advise Landlord of its intention duly to institute all steps necessary to cure the default and (ii) shall, as soon as reasonably practicable, duly institute and thereafter diligently
prosecute to completion all steps necessary to cure such default and, (2) that no notice of the opportunity to cure a default need be given, and no grace period whatsoever shall be allowed to Tenant, if the default is incurable or if the
covenant or condition the breach of which gave rise to default had, by reason of a breach on a prior occasion, been the subject of a notice hereunder to cure such default. 
  
 Notwithstanding anything to the contrary in this Article 21.7 contained, except to the extent prohibited by applicable law,
any statutory notice and grace periods provided to Tenant by law are hereby expressly waived by Tenant. 
  
 22. END OF TERM - ABANDONED PROPERTY 
  
 Upon the expiration or other termination of the term of this Lease, Tenant shall peaceably quit and surrender to Landlord the premises and all alterations and additions thereto, broom clean, in good order, repair and
condition (except as provided herein and in Articles 8.7, 18 and 20) excepting only ordinary wear and use and damage by fire or other casualty for which, under other provisions of this Lease, Tenant has no responsibility of repair or restoration.
Tenant shall remove all of its property and, to the extent specified by Landlord, in accordance with Article 12, all alterations and additions made by Tenant and all partitions wholly within the premises, and shall repair any damages to the premises
or the Building caused by their installation or-by such removal. Tenant’s obligation to observe or perform this covenant shall survive the expiration or other termination of the term of this Lease. 
  
 Tenant will remove any personal property from the Building and the premises
upon or prior to the expiration or termination of this Lease and any such property which shall remain in the Building or the premises thereafter shall be conclusively deemed to have been abandoned, and may either be retained by Landlord as its
property or sold or otherwise disposed of in such manner as Landlord may see fit. If any part thereof shall be sold, that Landlord may receive and retain the proceeds of such sale and apply the same, at its option, against the expenses of the sale,
the cost of moving and storage, any arrears of Yearly Rent, additional or other charges payable hereunder by Tenant to Landlord and any damages to which Landlord may be entitled under Article 21 hereof or pursuant to law. 
  
 If Tenant or anyone claiming under Tenant shall remain in possession of the
premises or any part thereof after the expiration or prior termination of the term of this Lease without any agreement in writing between Landlord and Tenant with respect thereto, then, prior to the acceptance of any payments for rent or use and
occupancy by Landlord, the person remaining in possession shall be deemed a tenant-at-sufferance. Whereas the parties hereby acknowledge that Landlord may need the premises after the expiration or prior termination of the term of the Lease for other
tenants and that the damages which Landlord may suffer as the result of Tenant’s holding-over cannot be determined as of the Execution Date hereof, in the event that Tenant so holds over, Tenant shall pay to Landlord, for each month or portion
thereof that Tenant shall retain possession of the premises after the expiration or termination of the Lease, whether by lapse of time or otherwise, in addition to all rental and other charges due and accrued under the Lease prior to the date of
termination, use and occupancy charges equal to one hundred fifty percent (150%) of the greater of (a) the then fair market rent for the premises as conclusively determined by Landlord or (b) the sum of the Yearly Rent and additional
rent at the rate payable monthly during the twelve (12) months immediately preceding the expiration or termination of the Lease. In addition, Tenant shall hold Landlord harmless from all damages which Landlord may suffer as the result of
Tenant’s holdover after the termination of the term of the Lease. 
  
 23.
SUBORDINATION 
  
 (a) Subject to any mortgagee’s or
ground lessor’s election, as hereinafter provided for, this Lease is subject and subordinate in all respects to all matters of record (including, without limitation, deeds and land disposition agreements), ground leases and/or underlying
leases, and all mortgages, any 

  

 30 

 
of which may now or hereafter be placed on or affect such leases and/or the real property of which the premises are a part, or any part of such real
property, and/or Landlord’s interest or estate therein, and to each advance made and/or hereafter to be made under any such mortgages, and to all renewals, modifications, consolidations, replacements and extensions thereof and all substitutions
therefor. This Article 23 shall be self-operative and no further instrument or subordination shall be required. In confirmation of such subordination, Tenant shall execute, acknowledge and deliver promptly any certificate or instrument that Landlord
and/or any mortgagee and/or lessor under any ground or underlying lease and/or their respective successors in interest may request, subject to Landlord’s, mortgagee’s and ground lessor’s right to do so for, on behalf and in the name
of Tenant under certain circumstances, as hereinafter provided. Tenant acknowledges that, where applicable, any consent or approval hereafter given by Landlord may be subject to the further consent’ or approval of such mortgagee and/or ground
lessor; and the failure or refusal of such mortgagee and/or ground lessor to give such consent or approval shall, notwithstanding anything to the contrary in this Lease contained, constitute reasonable justification for Landlord’s withholding
its consent or approval. Notwithstanding anything to the contrary in this Article 23 contained, as to any future mortgages, ground leases, and/or underlying lease or deeds of trust, the herein provided subordination and attornment shall be effective
only if the mortgagee, ground lessor or trustee therein, as the case may be, agrees, by a written instrument in recordable form and in the customary form of such mortgagee, ground lessor, or trustee (“Nondisturbance Agreement”) that, as
long as Tenant shall not be in terminable default of the obligations on its part to be kept and performed under the terms of this Lease, this Lease will not be affected and Tenant’s possession hereunder will not be disturbed by any default in,
termination, and/or foreclosure of such mortgage, ground lease, and/or underlying lease or deed of trust, as the case may be. Landlord hereby represents to Tenant that, as of the Execution Date of this Lease, there are no mortgages or ground leases
affecting the premises or the Building. 
  
 (b) Any such mortgagee
or ground lessor may from time to time subordinate or revoke any such subordination of the mortgage or ground lease held by it to this Lease. Such subordination or revocation, as the case may be, shall be effected by written notice to Tenant and by
recording an instrument of subordination or of such revocation, as the case may be, with the appropriate registry of deeds or land records and to be effective without any further act or deed on the part of Tenant. In confirmation of such
subordination or of such revocation, as the case may be, Tenant shall execute, acknowledge and promptly deliver any certificate or instrument that Landlord, any mortgagee or ground lessor may request, subject to Landlord’s, mortgagee’s and
ground lessor’s right to do so for, on behalf and in the name of Tenant under certain circumstances, as hereinafter provided. 
  
 (c) Without limitation of any of the provisions of this Lease, if any ground lessor or mortgagee shall succeed to the interest of Landlord by reason of
the exercise of its rights under such ground lease or mortgage (or the acceptance of voluntary conveyance in lieu thereof) or any third party (including, without limitation, any foreclosure purchaser or mortgage receiver) shall succeed to such
interest by reason of any such exercise or the expiration or sooner termination of such ground lease, however caused, then such successor may, upon notice and request to Tenant (which. in the case of a ground lease, shall be within thirty
(30) days after such expiration or sooner termination), succeed to the interest of Landlord under this Lease, provided, however, that such successor shall not: (i) be liable for any previous act or omission of Landlord under this Lease;
(ii) be subject to any offset, defense, or counterclaim which shall theretofore have accrued to Tenant against Landlord; (iii) have any obligation with respect to any security deposit unless it shall have been paid over or physically
delivered to such successor: or (iv) be bound by any previous modification of this Lease or by any previous payment of Yearly Rent for a period greater than one (1) month, made without such ground lessor’s or mortgagee’s consent
where such consent is required by applicable ground lease or mortgage documents. In the event of such succession to the interest of the Landlord — and notwithstanding that any such mortgage or ground lease may antedate this Lease — the
Tenant shall attorn to such successor and shall ipso facto be and become bound directly to such successor in interest to Landlord to perform and observe all the Tenant’s obligations under this Lease without the necessity of the execution of any
further instrument. Nevertheless, Tenant agrees at any time and from time to time during the term hereof to execute a suitable instrument in confirmation of Tenant’s agreement to attorn, as aforesaid, subject to 

  

 31 

 
Landlord’s, mortgagee’s and ground lessor’s right to do so for, on behalf and in the name of Tenant under certain circumstances, as
hereinafter provided. 
  
 (d) The term “mortgage(s)” as
used in this Lease shall include any mortgage or deed of trust. The term “mortgagee(s)” as used in this Lease shall include any mortgagee or any trustee and beneficiary under a deed of trust or receiver appointed under a mortgage or deed
of trust. The term “mortgagor(s)” as used in this Lease shall include any mortgagor or any grantor under a deed of trust. 
  
 (e) Tenant hereby irrevocably constitutes and appoints Landlord or any such mortgagee or ground lessor, and their respective successors in interest,
acting singly, Tenant’s attorney-in-fact to execute and deliver any such certificate or instrument for, on behalf and in the name of Tenant, but only if Tenant fails to execute, acknowledge and deliver any such certificate or instrument within
ten (10) days after Landlord or such mortgagee or such ground lessor has made written request therefor. 
  
 (f) Notwithstanding anything to the contrary contained in this Article 23, if all or part of Landlord’s estate and interest in the real property of
which the premises are a part shall be a leasehold estate held under a ground lease, then: (i) the foregoing subordination provisions of this Article 23 shall not apply to any mortgages of the fee interest in said real property to which
Landlord’s leasehold estate is not otherwise subject and subordinate; and (ii) the provisions of this Article 23 shall in no way waive. abrogate or otherwise affect any agreement by any ground lessor (x) not to terminate this Lease
incident to any termination of such ground lease prior to its term expiring or (y) not to name or join Tenant in an) action or proceeding by such ground lessor to recover possession of such real property or for any other relief. 
  
 (g) In the event of any failure by Landlord to perform, fulfill or observe
any agreement by Landlord herein, in no event will the Landlord be deemed to be in default under this Lease permitting Tenant to exercise any or all rights or remedies under this Lease until the Tenant shall have given written notice of such failure
to any mortgagee (ground lessor and/or trustee) of which Tenant shall have been advised and until a reasonable period of time shall have elapsed following the giving of such notice, during which such mortgagee (ground lessor and/or trustee) shall
have the right, but shall not be obligated, to remedy such failure. 
  
 24.
QUIET ENJOYMENT 
  
 Landlord covenants that if, and so long
as, Tenant keeps and performs each and every covenant, agreement, term, provision and condition herein contained on the part and on behalf of Tenant to be kept and performed, Tenant shall quietly enjoy the premises from and against the claims of all
persons claiming by, through or under Landlord subject, nevertheless, to the covenants, agreements, terms, provisions and conditions of this Lease and to the mortgages, ground leases and/or underlying leases to which this Lease is subject and
subordinate, as hereinabove set forth. 
  
 Without incurring any
liability to Tenant, Landlord may permit access to the premises and open the same, whether or not Tenant shall be present, upon any demand of any receiver, trustee, assignee for the benefit of creditors, sheriff, marshal or court officer entitled
to, or reasonably purporting to be entitled to, such access for the purpose of taking possession of, or removing, Tenant’s property or for any other lawful purpose (but this provision and any action by Landlord hereunder shall not be deemed a
recognition by Landlord that the person or official making such demand has any right or interest in or to this Lease, or in or to the premises), or upon demand of any representative of the fire, police, building, sanitation or other department of
the city, state or federal governments. 
  
 25. ENTIRE AGREEMENT — WAIVER
– SURRENDER 
  
 25.1 Entire Agreement. This Lease and
the Exhibits made a part hereof contain the entire and only agreement between the parties and any and all statements and representations, written and oral, including previous correspondence and agreements between the parties hereto, are merged
herein. Tenant acknowledges that all representations and statements upon which it relied in executing this Lease are contained herein and that the Tenant in no way relied upon any other statements or representations, written or oral. Any executory
agreement hereafter made shall be ineffective to change, modify, discharge or effect an abandonment of this Lease in whole or in 

  

 32 

 
part unless such executory agreement is in writing and signed by the party against whom enforcement of the change, modification, discharge or abandonment is
sought. 
  
 25.2 Waiver by Landlord. The failure of Landlord 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 and/or any other tenant in the Building 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 Landlord unless such waiver
be in writing signed by Landlord. No payment by Tenant or receipt by Landlord of a lesser amount than the monthly 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. 
  
 25.3 Surrender. No act or thing
done by Landlord during the term hereby demised shall be deemed an acceptance of a surrender of the premises, and no agreement to accept such surrender shall be valid, unless in writing signed by Landlord. No employee of Landlord or of
Landlord’s agents shall have any power to accept the keys of the premises prior to the termination of this Lease. The delivery of keys to any employee of Landlord or of Landlord’s agents shall not operate as a termination of the Lease or a
surrender of the premises. In the event that Tenant at any time desires to have Landlord underlet the premises for Tenant’s account, Landlord or Landlord’s agents are authorized to receive the keys for such purposes without releasing
Tenant from any of the obligations under this Lease, and Tenant hereby relieves Landlord of any liability for loss of or damage to any of Tenant’s effects in connection with such underletting. 
  
 26. INABILITY TO PERFORM - EXCULPATORY CLAUSE 
  
 Except as provided in Articles 4.1, 4.2, 8.8, 18 and 20 hereof, this Lease
and the obligations of Tenant to pay rent hereunder and perform all the other covenants, agreements, terms, provisions and conditions hereunder on the part of Tenant to be performed shall in no way be affected, impaired or excused because Landlord
is unable to fulfill any of its obligations under this Lease or is unable to supply or is delayed in supplying any service expressly or impliedly to be supplied or is unable to make or is delayed in making any repairs, replacements, additions,
alterations, improvements or decorations or is unable to supply or is delayed in supplying any equipment or fixtures if Landlord is prevented or delayed from so doing by reason of strikes or labor troubles or any other similar or dissimilar cause
whatsoever beyond Landlord’s reasonable control, including but not limited to, governmental preemption in connection with a national emergency or by reason of any rule, order or regulation of any department or subdivision thereof of any
governmental agency or by reason of the conditions of supply and demand which have been or are affected by war, hostilities or other similar or dissimilar emergency. In each such instance of inability of Landlord to perform, Landlord shall exercise
reasonable diligence to eliminate the cause of such inability to perform. 
  
 Tenant shall neither assert nor seek to enforce any claim against Landlord, or Landlord’s agents or employees, or the assets of Landlord or of Landlord’s agents or employees, for breach of this Lease or
otherwise, other than against Landlord’s interest in the Building of which the premises are a part and in the uncollected rents, issues and profits thereof, and Tenant agrees to look solely to such interest for the satisfaction of any liability
of Landlord under this Lease, it being specifically agreed that in no event shall Landlord or Landlord’s agents or employees (or any of the officers, trustees, directors, partners, beneficiaries, joint ventures, members, stockholders or other
principals or representatives, and the like, disclosed or undisclosed, thereof) ever be personally liable for any such liability. This paragraph shall not limit any right that Tenant might otherwise have to obtain injunctive relief against Landlord
or to take any other action which shall not involve the personal liability of Landlord to respond in monetary damages from Landlord’s assets other than the Landlord’s interest in said real estate, as aforesaid. In no event shall Landlord
or Landlord’s agents or employees (or any of the officers, trustees, directors, partners, beneficiaries, joint ventures, members, stockholders or other principals or representatives and the like, 

  

 33 

 
disclosed or undisclosed, thereof) ever be liable for loss of profits, loss of the value of Tenant’s business, or consequential or incidental damages.
Without limiting the foregoing, in no event shall Landlord or Landlord’s agents or employees (or any of the officers, trustees, directors. partners, beneficiaries. Joint ventures, members, stockholders or other principals or representatives and
the like, disclosed or undisclosed, thereof) ever be liable for lost profits of Tenant. If by reason of Landlord’s failure to acquire title to the real property of which the premises are a part or to complete construction of the Building or
premises, Landlord shall be held to be in breach of this Lease, Tenant’s sole and exclusive remedy shall be a right to terminate this Lease. 
  
 27. BILLS AND NOTICES 
  
 Any notice, consent, request, bill, demand or statement hereunder by either party to the other party shall be in writing and, if received at
Landlord’s or Tenant’s address, shall be deemed to have been duly given when either delivered or served personally or mailed in a postpaid envelope, deposited in the United States mail addressed to Landlord at its address as stated in
Exhibit I and to Tenant at the premises (or at Tenant’s address as stated in Exhibit 1, if mailed prior to Tenant’s occupancy of the premises), and, with respect to bills and statements for reimbursement, to Tenant’s office at the
address set forth in Exhibit I , Attention: Controller, or if any address for notices shall have been duly changed as hereinafter provided, if mailed as aforesaid to the party at such changed address. Either party may at any time change the address
or specify an additional address for such notices, consents, requests, bills, demands or statements by delivering or mailing, as aforesaid, to the other party a notice stating the change and setting forth the changed or additional address, provided
such changed or additional address is within the United States. 
  
 If Tenant is a partnership, Tenant, for itself, and on behalf of all of its partners, hereby appoints Tenant’s Service Partner, as identified on Exhibit 1, to accept service of any notice. consent, request, bill, demand or statement
hereunder by Landlord and any service of process in any judicial proceeding with respect to this Lease on behalf of Tenant and as agent and attorney-in-fact for each partner of Tenant. 
  
 All bills and statements for reimbursement or other payments or charges due from Tenant to Landlord hereunder shall be due
and payable in full thirty (30) days, unless herein otherwise provided, after submission thereof by Landlord to Tenant. Tenant’s failure to make timely payment of any amount indicated by such bills and statements, whether for work done by
Landlord at Tenant’s request, reimbursement provided for by this Lease or for any other sums properly owing by Tenant to Landlord, shall be treated as a default in the payment of rent, in which event Landlord shall have all rights and remedies
provided in this Lease for the nonpayment of rent. 
  
 28. PARTIES BOUND -
SEISIN OF TITLE 
  
 The covenants, agreements, terms,
provisions and conditions of this Lease shall bind and benefit the successors and assigns of the parties hereto with the same effect as if mentioned in each instance where a party hereto is named or referred to, except that no violation of the
provisions of Article 16 hereof shall operate to vest any rights in any successor or assignee of Tenant and that the provisions of this Article 28 shall not be construed as modifying the conditions of limitation contained in Article 21 hereof.

  
 If, in connection with or as a consequence of the sale,
transfer or other disposition of the real estate (land and/or Building, either or both, as the case may be) of which the premises are a part, Landlord ceases to be the owner of the reversionary interest in the premises, Landlord shall be entirely
freed and relieved from the performance and observance thereafter of all covenants and obligations hereunder on the part of Landlord to be performed and observed, it being understood and agreed in such event (and it shall be deemed and construed as
a covenant running with the land) that the person succeeding to Landlord’s ownership of said reversionary interest shall thereupon and thereafter assume, and perform and observe, any and all of such covenants and obligations of Landlord.

  
 29. MISCELLANEOUS 
  
 29.1 Separability. If any provision of this Lease or portion of such
provision or the application thereof to any person or circumstance is for any reason held invalid or unenforceable, the remainder of the Lease (or the remainder of such provision) and the application thereof to other persons or circumstances shall
not be affected thereby.

 29.2 Captions, etc. The captions are inserted only as a matter of convenience and for reference, and in
no way define, limit or describe the scope of this Lease or the intent of any provisions thereof. References to “State” shall mean, where appropriate, the District of Columbia and other Federal territories, possessions, as well as a state
of the United States. 
  
 29.3 Broker. Tenant represents and
warrants that it has not directly or indirectly dealt, with respect to the leasing of office space in the Building or the Park with any broker or had its attention called to the premises or other space to let in the Building or the Park by anyone
other than the broker, person or firm, if any, designated in Exhibit 1. Tenant agrees to defend, exonerate and save harmless and indemnify Landlord and anyone claiming by, through or under Landlord against any claims for a commission arising in
breach of the representation and warranty set forth in the immediately preceding sentence, provided that Landlord shall be solely responsible for the payment of brokerage commissions to Avalon Partners, Inc. and Landlord shall have no obligation for
the payment of brokerage commissions to Julien J. Studley, Inc. (the parties hereby acknowledging that Avalon Properties, Inc. shall be solely responsible for the payment of brokerage commissions to Julien J. Studley, Inc.). 
  
 29.4 Modifications. If in connection with obtaining financing for the
Building, a bank, insurance company, pension trust or other institutional lender shall request reasonable modifications in this Lease as a condition to such financing, Tenant will not withhold, delay or condition its consent thereto, provided that

Tenant, specifically otherwise elect; and 
  
 (b) that, except as
aforesaid, such mortgagee and/or ground lessor shall be treated as having assumed the Landlord’s obligations thereunder only upon foreclosure of such

after having given notice of its exercise of the option stated in Article 23 hereof to succeed to the interest of the Landlord under this Lease.

notice of lease set forth the rent or other charges payable by Tenant under the Lease; and such notice shall expressly state that it is executed pursuant to the provisions contained in the Lease, and is not intended to vary the terms and conditions

 RIDER TO LEASE 
  
 LANDLORD: EOP-New England Executive Park, L.L.C. 
 TENANT: Learning Tree International USA, Inc. 
  
 The subject Lease is hereby amended as follows: 
  

	1.	TENANT’S OPTION TO EXTEND THE TERM OF THE LEASE 

  
 A. On the conditions, which conditions Landlord may waive, at its election. by written notice to Tenant at any time, that Tenant is not in default, beyond
the expiration of applicable notice and grace periods, of its covenants and obligations under the Lease, and that Learning Tree International USA. Inc. itself. or an Affiliated Entity, as defined in Article 16C, is occupying the entirety of the
premises then demised to Tenant. both as of the time of option exercise and as of the commencement of the hereinafter described additional term, and provided that Tenant has not exercised its right to terminate the term of the Lease pursuant to
Paragraph 5 of this Rider, Tenant shall have the option to extend the term of this Lease for one (1) additional five (5) year term, such additional term commencing as of the expiration of the initial term of the Lease. Tenant may exercise
such option to extend by giving Landlord written notice on or before the date twelve (12) months prior to the expiration date of the initial term of the Lease. Upon the timely giving of such notice, the term of this Lease shall be deemed
extended upon all of the terms and conditions of this Lease, except that Landlord shall have no obligation to construct or renovate the premises or to provide a contribution to Tenant and that the Yearly Rent, Operating Costs in the Base Year, and
Tax Base during such additional term shall be as hereinafter set forth. If Tenant fails to give timely notice, as aforesaid, Tenant shall have no further right to extend the term of this Lease, time being of the essence of this Paragraph 1.

  
 B. Yearly Rent 
  
 The Yearly Rent during the additional term shall be based upon the Fair
Market Rental Value, as defined in Paragraph 2 of this Rider. as of the commencement of the additional term, of the premises then demised to Tenant, provided however, that in no event shall the sum of Yearly Rent, Operating Expense Excess and Tax
Excess payable by Tenant for any twelve-(12)-month period during the additional term be less than the sum of Yearly Rent, Operating Expense Excess and Tax Excess payable by Tenant in respect of the twelve-(12)-month period immediately preceding the
commencement of the additional term. 
  
 C. Operating Costs in
the Base Year 
  
 The Operating Costs in the Base Year during
the additional term shall be equal to the actual amount of Operating Costs for the calendar year immediately preceding the calendar year in which occurs the commencement of such additional term. 
  
 D. Tax Base 
  
 The Tax Base during the additional term shall be equal to the actual amount
of Taxes for the fiscal tax year immediately preceding the fiscal tax year in which occurs the commencement of such additional term. 
  
 E. Tenant shall have no further option to extend the term of the Lease other than the one (1) additional five (5) year term herein provided.

  
 F. Notwithstanding the fact that upon Tenant’s exercise
of the herein option to extend the term of the Lease such extension shall be self-executing, as aforesaid, the parties shall promptly execute a lease amendment reflecting such additional term after Tenant exercises the herein option, except that the
Yearly Rent payable in respect of such additional term, the Operating Costs in the Base Year during such additional term, and the Tax Base during such additional term, may not be set forth in said amendment. Subsequently, after such Yearly Rent,
Operating Costs in the Base Year, and Tax Base are determined, the parties shall execute a written agreement confirming the same. The execution of such lease amendment 

  

 38 

 
shall not be deemed to waive any of the conditions to Tenant’s exercise of its rights under this Paragraph 1, unless otherwise specifically provided in
such lease amendment. 
  

	2.	DEFINITION OF FAIR MARKET RENTAL VALUE 

  
 For the purposes of this Rider: 
  
 A. “Fair Market Rental Value” shall be computed as of the date in question at the then current annual rental charge (i.e., the sum of Yearly
Rent plus escalation bases and other charges), including provisions for subsequent increases and other adjustments for leases or agreements to lease then currently being executed in comparable space located in the Building, or if no leases or
agreements to lease are then currently executed in the Building, the Fair Market Rental Value shall be determined by reference to leases or agreements to lease then currently being executed for comparable space located elsewhere in New England
Executive Park or in comparable buildings in comparable locations in Burlington, Massachusetts. In determining Fair Market Rental Value, the following factors, among others, shall be taken into account and given effect: size, location of premises,
lease term, condition of building, condition of premises, economic concessions then being granted by Landlord to tenants, and services provided by the Landlord. 
  
 B. Dispute as to Fair Market Rental Value 
  
 Landlord shall initially designate Fair Market Rental Value, and Landlord shall furnish data in support of such designation.
If Tenant disagrees with Landlord’s designation of a Fair Market Rental Value, Tenant shall have the right, by written notice given within thirty (30) days after Tenant has been notified of Landlord’s designation, to submit such Fair
Market Rental Value to arbitration. Fair Market Rental Value shall be submitted to arbitration as follows: Fair Market Rental Value shall be determined by impartial arbitrators, one to be chosen by the Landlord, one to be chosen by Tenant, and a
third to be selected, if necessary, as below provided. The unanimous written decision of the two first chosen, without selection and participation of a third arbitrator, or otherwise, the written decision of a majority of three arbitrators chosen
and selected as aforesaid, shall be conclusive and binding upon Landlord and Tenant. Landlord and Tenant shall each notify the other of its chosen arbitrator within ten (10) days following the call for arbitration and, unless such two
arbitrators shall have reached a unanimous decision within thirty (30) days after their designation, they shall so notify the President of the Boston Bar Association (or such organization as may succeed to said Boston Bar Association) and
request him to select an impartial third arbitrator, who shall be a real estate counselor or a broker dealing with like types of properties, to determine Fair Market Rental Value as herein defined. Such third arbitrator and the first two chosen
shall, subject to commercial arbitration rules of the American Arbitration Association, hear the parties and their evidence and render their decision within thirty (30) days following the conclusion of such hearing and notify Landlord and
Tenant thereof. Landlord and Tenant shall bear the expense of the third arbitrator (if any) equally. The decision of the arbitrator shall be binding and conclusive, and judgment upon the award or decision of the arbitrator may be entered in the
appropriate court of law (as identified on Exhibit I); and the parties consent to the jurisdiction of such court and further agree that any process or notice of motion or other application to the Court or a Judge thereof may be served outside the
State wherein the Building is situated by registered mail or by personal service, provided a reasonable time for appearance is allowed. If the dispute between the parties as to a Fair Market Rental Value has not been resolved before the commencement
of Tenant’s obligation to pay rent based upon such Fair Market Rental Value, then Tenant shall pay Yearly Rent and other charges under the Lease in respect of the premises in 1 question based upon the Fair Market Rental Value designated by
Landlord until either the agreement of the parties as to the Fair Market Rental Value, or the decision of the arbitrators, as the case may be, at which time Tenant shall pay any underpayment of rent and other charges to Landlord, or Landlord shall
refund any overpayment of rent and other charges to Tenant.

(ii) Tenant may, at Tenant’s expense and subject to the provisions of this Agreement (including, without limitation, subparagraph P hereof), have access to and use (and tie into) the Central Building System 

  

 43 

 
for the uses permitted hereunder, and (ii) commencing upon Tenant’s use of the Central Building System and continuing thereafter throughout the
term, the Yearly Rent payable hereunder shall be adjusted to be that which is reasonably designated by Landlord from time to time based upon Landlord’s determination of the fair market value of the access rights to the Central Building System
granted herein.

replace the Central Building System, in accordance with the standards for the repair and maintenance of such systems generally prevailing in the industry from time to time, so as to eliminate any material interruption or other adverse effects caused
by malfunction, damage or destruction of the Central Building System, the cost of which shall be borne by Tenant if the problem was caused by the act or omission of Tenant or its agents, contractors or employees. Notwithstanding the foregoing,
Landlord’s obligation to maintain, repair or replace the Central Building System shall apply only to the extent necessary to reach premises in the Building that are then used by tenants after the malfunction, damage or destruction or that, if
damaged or destroyed, will be again used by tenants upon the completion of restoration or repair thereof. In no event shall Tenant have any claim or right to make any claim against Landlord whatsoever for any damages, including, without limitation,
consequential or incidental damages, or lost profits, in any such circumstance.
