 WITNESSETH: Landlord hereby leases to Tenant and Tenant hereby hires from Landlord, a portion of the 3rd floor and a portion of the 17th floor as shown on the floor plans annexed hereto and made
a part hereof as Exhibit A (the “Demised Premises” or “demised premises”, whether capitalized or not) in the building known as 67 a/k/a 75 Broad Street in the Borough of Manhattan, City of New York (the “Building” or
“Building”, whether capitalized or not), for the term of approximately ten (10) years and four (4) months (or until such term shall sooner cease and expire as hereinafter provided) which shall commence upon the unconditional
execution of this Lease by Landlord and Tenant (the “Commencement Date”) and shall expire nevertheless on the last day of the 124th calendar month following the Commencement Date (the “Expiration Date”), both dates inclusive, at annual rental rates, as provided in the Rent Schedule annexed hereto and made a part hereof as Exhibit B (the
“fixed rent” or “Fixed Rent” or “Fixed Annual Rent,” whether capitalized or not), which Tenant agrees to pay in lawful money of the United States which shall be legal tender in payment of all debts and dues, public and
private, at the time of payment, in equal monthly installments in advance on the first day of each month during said term, at the office of Landlord or such other place as Landlord may designate, without any set off, counterclaim or deduction
whatsoever. The first (1st) monthly installment of fixed rent in the amount of $25,579.75 shall be paid by Tenant upon execution of this Lease and shall be applied as a credit against the Fixed Rent due in months 5 and 6 of the first Lease
Year, pursuant to Article 41 hereof. 
 The parties hereto, for themselves, their heirs, distributees, executors, administrators, legal
representatives, successors and assigns, hereby covenant as follows: 
 1. Rent. Tenant shall pay the rent as above and as hereinafter
provided. 
 2. Occupancy. Tenant shall use and occupy the Demised Premises for telecommunications, switching, transmission, data
center and for executive and general office use related therewith and for no other purpose. 
 3. Alterations: Tenant shall make no
changes in or to the Demised Premises of any nature without Landlord’s prior written consent provided, however, that Tenant may make purely decorative changes such as painting and installation of partitions and carpeting without Landlord’s
consent, but upon notice to Landlord. Subject to the prior written consent of Landlord, not to be unreasonably withheld or delayed and to the provisions of this Article, Tenant at Tenant’s expense, may make non-structural alterations,
installations, additions or improvements which do not affect utility services or plumbing and electrical lines, in or to the interior of the Demised Premises using licensed and reputable contractors or mechanics first approved by Landlord, not to be
unreasonably withheld or delayed. Landlord shall not charge Tenant any fee or other charge for the supervision of Tenant’s initial improvements. Tenant shall not be responsible for Landlord’s security costs, during normal business hours,
during the construction of Tenant’s initial improvements or initial alterations and for Tenant’s initial move into the Building. All labor employed by Tenant shall be harmonious and compatible with the labor employed by Landlord and other
tenants in the Building, it being agreed that if such labor shall be incompatible, Tenant shall forthwith on Landlord’s demand withdraw such labor from the Demised Premises. Tenant may use its own contractor(s), subject to Landlord’s prior
reasonable approval thereof, for performing any work in and to or from the Demised Premises. Tenant shall, at its expense, before making any alterations, additions, installations or improvements obtain all permits, approval and certificates required
by any governmental or quasi-governmental bodies and (upon completion) certificates of final approval thereof and shall deliver promptly duplicates of all such permits, approvals and certificates to Landlord. Tenant agrees to carry and will cause
Tenant’s contractors and sub-contractors to carry such workman’s compensation, general liability, personal and property damage insurance as Landlord may require. 
 As a condition to Tenant performing any work or alterations in or to the Demised Premises and prior to the commencement of any such work or alterations,
Tenant shall furnish a contractor’s performance and payment bond guaranteeing lien free completion of the work or alterations and payment of obligations to its sub-contractors and suppliers. The amount, form and substance of such bond shall be
reasonably acceptable to Landlord, providing for a direct 

 
right of action against the surety by a claimant, naming Landlord and its Superior Mortgagee as co-obligees, and shall be underwritten by a surety company
authorized to do and doing business in the State of New York and with a “Best” rating of A, or better. 
 Tenant shall not file any
mechanic’s, laborer’s or materialman’s lien, or suffer or permit any such lien to be filed against the Demised Premises, including the Building or any part thereof by reason of work, labor, services, or materials requested and/or
supplies claimed to have been requested by or on behalf of Tenant; and if such lien shall at any time be so filed, within thirty (30) days after said filing Tenant shall cause said lien to be canceled and discharged of record. To the extent
Tenant fails to remove any mechanic’s, laborer’s or materialman’s lien filed against the Demised Premises, including the Building or any part thereof within the time period set forth above, the same shall be deemed a default hereunder
entitling Landlord to all rights and remedies pursuant to law and this Lease including without limitation the right to arrange to bond or pay the amount of such claim upon which the lien is based and/or utilize the Security (as defined below)
therefor and Tenant shall thereafter pay and be liable to Landlord for the amount so paid by Landlord, as additional rent, immediately upon demand, together with interest thereon at the highest rate permissible by law and all costs and expenses,
including reasonable attorneys’ fees incurred by Landlord in procuring the discharge of such lien, shall be due and payable by Tenant to Landlord as additional rent upon demand of Landlord. The provisions of this paragraph shall survive the
termination of this Lease. 
 All fixtures and all paneling, partitions, equipment, railings and like installations, installed in the Demised
Premises at any time, either by Tenant or by Landlord on Tenant’s behalf, shall be removed by Tenant on or prior to the Expiration Date. Landlord hereby requires Tenant, at Tenant’s expense, to remove all switching equipment and wiring and
other equipment appurtenant thereto and the HVAC system prior to the expiration of this Lease. Notwithstanding anything contained herein to the contrary, the Improvements (as hereinafter defined) (i) are and remain the property of Landlord,
(ii) shall be surrendered by Tenant together with the Demised Premises at the end of the term, in accordance with Article 24 hereof and in no event shall Tenant remove the Improvements. Upon Tenant’s removal of any furniture, fixtures,
equipment and installations from the Demised Premises as aforesaid, Tenant shall immediately and at its expense, repair and restore the Demised Premises (and/or the Building, as the case may be) to the condition existing prior to installation and
repair any damage to the Demised Premises or the Building due to such removal. All property to be removed by Tenant at the end of the term remaining in the Demised Premises after the Expiration Date shall be deemed abandoned and may, at the election
of Landlord, either be retained as Landlord’s property or removed from the Demised Premises by Landlord, at Tenant’s expense. 
 Commencing on the first anniversary of the Commencement Date and continuing annually thereafter throughout the term of this Lease, Tenant shall submit to Landlord a structural inventory. Landlord shall also have the right, on an annual
basis, to access the Demised Premises, subject to the provisions of Article 13 hereof, in order to review Tenant’s structural loading. 
 Tenant has submitted all plans and specifications as Landlord shall require in connection with Tenant’s request for Landlord’s approval of the work Tenant requires to make to the Demised Premises suitable for its occupancy and use
(“Initial Alteration Work”), and Landlord agrees to notify Tenant of its approval or disapproval within ten (10) business days of full execution hereof. All costs and expenses associated with the review of the Initial Alteration Work
shall be paid by Tenant in accordance with the provisions of Article 43 of this lease. Subject to all applicable laws, and the provisions of this lease, Tenant may perform the Initial Alteration Work twenty four (24) hours per day, seven
(7) days per week. 
 Tenant shall be required to use the Building’s Class E System contractor for all interfacing with the fire
detection system as well as the electrical contractor for work in the Demised Premises. 
 With respect to any proposed work, Tenant shall,
submit (a) “load letter” evidencing Tenant’s proposed floor and electrical loads and (b) final “as built” plans. 
 4. Repairs: Landlord shall maintain and repair the exterior of and the public portions of the Building and all Building systems servicing the Demised Premises. Tenant shall, throughout the term of this lease, take good care of the
Demised Premises including the windows and window frames and the fixtures, appurtenances and Improvements therein and at Tenant’s sole cost and expense promptly make all repairs thereto and to the Building, whether structural or non-structural
in nature, caused by or resulting from the carelessness, omission, neglect or improper conduct of Tenant, Tenant’s servants, employees, invitees, or licensees. Tenant shall also repair all damage to the Building and the Demised Premises caused
by the moving of Tenant’s fixtures, furniture or equipment. All the aforesaid repairs shall be of quality or class equal to the original work or construction. If Tenant fails, after ten (10) days notice, to proceed with due diligence to
make repairs required to be made by Tenant, the same may be 

 
made by the Landlord at the expense of Tenant, and the expenses thereof incurred by Landlord shall be collectible, as additional rent, after rendition of a
bill or statement therefor. If the Demised Premises be or become infested with vermin, Tenant shall, at its expense, cause the same to be exterminated. Tenant shall give Landlord prompt notice of any defective condition in any plumbing, heating
system or electrical lines leading to the Demised Premises and following such notice, Landlord shall remedy the condition with due diligence, but at the expense of Tenant, if repairs are necessitated by damage or injury attributable to Tenant,
Tenant’s servants, agents, employees, invitees or licensees as aforesaid. To the extent any plumbing, heating system or electrical lines or other like installations are installed by Tenant, Landlord shall have no responsibility to repair and
maintain the same, the repair and maintenance of said installations being Tenant’s sole responsibility. There shall be no allowance to the Tenant for a diminution of rental value and no liability on the part of Landlord by reason of
inconvenience, annoyance or injury to business arising from Landlord, Tenant or others making or failing to make any repairs, alterations, additions or improvements in or to any portion of the Building or the Demised Premises or in and to the
fixtures, appurtenances or equipment thereof. The provisions of this Article 4 with respect to the making of repairs shall not apply in the case of fire or other casualty with regard to which Article 9 shall apply. 
 5. Window Cleaning: Tenant will not clean nor require, permit, suffer or allow any window in the Demised Premises to be cleaned from the outside
in violation of Section 202 of the New York State Labor Law or any other applicable law or of the Rules of the Board of Standards and Appeals, or of any other Board or body having or asserting jurisdiction. 
 6. Requirements of Law, Fire Insurance, Floor Loads: Prior to the commencement of the lease term, if Tenant is then in possession, and at all
times thereafter, Tenant shall, at Tenant’s sole cost and expense, promptly comply with all present and future laws, orders and regulations of all state, federal, municipal and local governments, departments, commissions and boards and any
direction of any public officer pursuant to law, and all orders, rules and regulations of the New York Board of Fire Underwriters, or the Insurance Services Office, or any similar body which shall impose any violation, order or duty upon Landlord or
Tenant with respect to the Demised Premises, whether or not arising out of Tenant’s use or manner of use thereof, or, with respect to the Building, if arising out of Tenant’s use or manner of use of the Demised Premises or the Building
(including the use permitted under the lease). Nothing herein shall require Tenant to make structural repairs or alterations unless Tenant has, by its manner of use of the Demised Premises or method of operation therein, violated any such laws,
ordinances, orders, rules, regulations or requirements with respect thereto. Tenant shall also be responsible for complying with the Americans with Disabilities Act (“ADA”) as it relates to the Demised Premises only. Landlord shall be
responsible for compliance with ADA as it relates to the Building generally but not the Demised Premises or any other portion of the Building occupied by other tenants. Tenant shall not permit any act or thing to be done in or to the Demised
Premises which is contrary to law, or which will invalidate or be in conflict with public liability, fire or other policies of insurance at any time carried by or for the benefit of Landlord. Tenant shall not keep anything in the Demised Premises
except as now or hereafter permitted by the Fire Department, Board of Fire Underwriters, Fire Insurance Rating Organization and other authority having jurisdiction, and then only in such manner and such quantity so as not to increase the rate for
fire insurance applicable to the Building, nor use the Demised Premises in a manner which will increase the insurance rate for the Building or any property located therein over that in effect prior to the commencement of Tenant’s occupancy. If
by reason of failure to comply with the foregoing the fire insurance rate shall, at the beginning of this lease or at any time thereafter, be higher than it otherwise would be, then Tenant shall reimburse Landlord, as additional rent hereunder, for
that portion of all fire insurance premiums thereafter paid by Landlord which shall have been charged because of such failure by Tenant. In any action or proceeding wherein Landlord and Tenant are parties, a schedule or “make-up” or rate
for the Building or Demised Premises issued by a body making fire insurance rates applicable to said Demised Premises, shall be conclusive evidence of the facts therein stated and of the items and changes in the fire insurance rates applicable to
the Demised Premises. Tenant shall not place a load upon any floor of the Demised Premises exceeding the floor load per square foot area which it was designed to carry and which is allowed by law, as further delineated in the Certificate of
Occupancy for the Building, attached hereto as Exhibit E. Landlord reserves the right to prescribe the weight and position of all safes, business machines and mechanical equipment. Such installations shall be placed and maintained by Tenant, at
Tenant’s expense, in settings sufficient, in Landlord’s judgement, to absorb and prevent vibration, noise and annoyance. Commencing on the first anniversary of the Commencement Date and continuing annually thereafter throughout the term of
this Lease, Tenant shall submit to Landlord a structural inventory. Landlord shall also have the right, on an annual basis, to access the Demised Premises, subject to the provisions of Article 13 hereof, to review Tenant’s structural loading.

 7. Subordination: This lease is subject and subordinate to all ground or underlying leases and to
all mortgages which may now or hereafter affect such leases or the real property of which the Demised Premises form a part thereof, and to all renewals, modifications, consolidations, replacements and extensions of any such underlying leases and
mortgages. This clause shall be self-operative and no further instrument or subordination shall be required by any ground or underlying lessor or by any mortgagee, affecting any lease or the real property of which the Demised Premises are a part. In
confirmation of such subordination, Tenant shall execute promptly any certificate that Landlord may request. 
 Landlord agrees that it shall
use its reasonable efforts to obtain and deliver to Tenant, as to the existing mortgage and any future mortgages and/or ground leases covering the real property of which the Demised Premises form a part, a non-disturbance agreement in recordable
form (or such agreement shall be contained in such existing mortgage) from the holder of any such existing or future mortgage and/or ground leases, providing in substance that provided Tenant shall have entered into possession and occupancy of the
Demised Premises and commenced payment of fixed rent and additional rent hereunder, and so long as Tenant is not in default in its obligations for the payment of fixed rent and additional rent and in the performance of the other terms, covenants and
conditions to be performed on its part under this Lease beyond applicable notice and cure periods, its possession of the Demised Premises will not be disturbed during the term hereof, notwithstanding the foreclosure of any such mortgage and/or
ground lease, and Tenant will not be named as a party defendant in any foreclosure proceedings brought for the recovery of possession, it being hereby covenanted and agreed to by Tenant that the holder of any existing or future mortgage and/or
ground lease, or anyone claiming by, through or under said holder shall not be: (a) liable for any act or omission for any prior landlord (including Landlord), (b) subject to any offsets or defenses which Tenant might have against any
prior landlord (including Landlord), (c) bound by any fixed rent or additional rent or other charges which Tenant might have paid for more than the current month to a prior landlord (including Landlord), or (d) bound by any modification of
this Lease made without the consent of such mortgagee or ground lessor, as the case may be. 
 The inability of Landlord to obtain such
agreement shall not be deemed a default on Landlord’s part of its obligations hereunder, or impose any claim in favor of Tenant against Landlord by reason thereof, or affect the validity of this Lease. Tenant agrees to (i) execute and
deliver to such mortgagee a nondisturbance and attornment agreement in form and substance customarily adopted by such mortgagee and (ii) reimburse Landlord for all reasonable expenses incurred by Landlord in connection therewith, including
legal expenses. 
 8. Property - Loss, Damage, Reimbursement, Indemnity: Landlord or its agents shall not be liable for any damage to
property of Tenant or of others entrusted to employees of the Building, nor for loss of or damage to any property of Tenant by theft or otherwise, nor for any injury or damage to persons or property resulting from any cause of whatsoever nature,
unless caused by or due to the negligence or willful acts of Landlord, its agents, servants or employees. Landlord or its agents shall not be liable for any damage caused by other tenants or persons in, upon or about said Building or caused by
operations in connection of any private, public or quasi public work. If at any time any windows of the Demised Premises are temporarily closed, darkened or bricked up (or permanently closed, darkened or bricked up, if required by law) for any
reason whatsoever including, but not limited to Landlord’s own acts, Landlord shall not be liable for any damage Tenant may sustain thereby and Tenant shall not be entitled to any compensation therefor nor any abatement or diminution of rent
nor shall the same release Tenant from its obligations hereunder nor constitute an actual or constructive eviction. Tenant shall indemnify and save harmless Landlord against and from all liabilities, obligations, damages, penalties, claims, costs
and expenses for which Landlord shall not be reimbursed by insurance, including reasonable attorney’s fees, paid, suffered or incurred as a result of any breach by Tenant, Tenant’s agents, contractors, employees, invitees, or licensees, of
any covenant or condition of this lease, or the carelessness, negligence or improper conduct of the Tenant, Tenant’s agents, contractors, employees, invitees or licensees. Tenant’s liability under this lease extends to the acts and
omissions of any sub-tenant and any sub-tenant, agent, contractor, employee, invitee or licensee of any subtenant. In case any action or proceeding is brought against Landlord by reason of any such claim, Tenant, upon written notice from Landlord,
will, at Tenant’s expense, resist or defend such action or proceeding by counsel approved by Landlord in writing, such approval not to be unreasonably withheld. 
 9. Destruction, Fire and Other Casualty: (a) If the Demised Premises or any part thereof shall be damaged by fire or other casualty, Tenant shall give immediate notice thereof to Landlord and this lease
shall continue in full force and effect except as hereinafter set forth. (b) If the Demised Premises are partially damaged or rendered partially unusable by fire or other casualty, the damages thereto shall be repaired by and at the expense of
Landlord and the rent, until such repair shall be substantially completed, shall be apportioned from the day following the casualty according to the portion of the Demised Premises which is usable. (c) If the Demised Premises are totally
damaged or rendered wholly unusable by fire or other 

 
casualty, then the rent shall be proportionately paid up to the time of the casualty and thenceforth shall cease until the date when the Demised Premises
shall have been repaired and restored by Landlord, subject to Landlord’s right to elect not to restore the same as hereinafter provided. (d) If the Demised Premises are rendered wholly unusable or (whether or not the Demised Premises are
damaged in whole or in part) if the Building shall be so damaged that Landlord shall decide to demolish it or to rebuild it, then, in any such events, Landlord may elect to terminate this lease by written notice to Tenant, given within 90 days after
such fire or casualty, specifying a date for the expiration of the lease, which date shall not be more than 60 days after the giving of such notice, and upon the date specified in such notice the term of this lease shall expire as fully and
completely as if such date were the date set forth above for the termination of this lease and Tenant shall forthwith quit, surrender and vacate the Demised Premises without prejudice however, to Landlord’s rights and remedies against Tenant
under the lease provisions in effect prior to such termination, and any rent owing shall be paid up to such date and any payments of rent made by Tenant which were on account of any period subsequent to such date shall be returned to Tenant. Unless
Landlord shall serve a termination notice as provided for herein, Landlord shall make the repairs and restorations under the conditions of (b) and (c) hereof, with all reasonable expedition, subject to delays due to adjustment of insurance
claims, labor troubles and causes beyond Landlord’s control. After any such casualty, Tenant shall cooperate with Landlord’s restoration by removing from the Demised Premises as promptly as reasonably possible, all of Tenant’s
salvageable inventory and movable equipment, furniture, and other property. Tenant’s liability for rent shall resume five (5) days after written notice from Landlord that the Demised Premises are substantially ready for Tenant’s
occupancy. (e) Nothing contained hereinabove shall relieve Tenant from liability that may exist as a result of damage from fire or other casualty. Notwithstanding the foregoing, each party shall look first to any insurance in its favor before
making any claim against the other party for recovery for loss or damage resulting from fire or other casualty, and to the extent that such insurance is in force and collectible and to the extent permitted by law, Landlord and Tenant each hereby
releases and waives all right of recovery against the other or any one claiming through or under each of them by way of subrogation or otherwise. The foregoing release and waiver shall be in force only if both releasors’ insurance policies
contain a clause providing that such a release or waiver shall not invalidate the insurance. If, and to the extent, that such waiver can be obtained only by the payment of additional premiums, then the party benefitting from the waiver shall pay
such premium within ten (10) days after written demand or shall be deemed to have agreed that the party obtaining insurance coverage shall be free of any further obligation under the provisions hereof with respect to waiver of subrogation.
Tenant acknowledges that Landlord will not carry insurance on Tenant’s furniture and or furnishing or any fixtures or equipment, improvements, or appurtenances removable by Tenant and agrees that Landlord will not be obligated to repair any
damage thereto or replace the same. (f) Tenant hereby waives the provisions of Section 227 of the Real Property Law and agrees that the provisions of this Article shall govern and control in lieu thereof. If all or substantially all of the
Demised Premises (as reasonably determined by Landlord) is totally damaged by reason of fire or other casualty and same will not reasonably be restored to the condition existing as of the Commencement Date (as reasonably determined by Landlord)
within two hundred forty (240) days after the casualty or same is not substantially restored to the condition existing as of the Commencement Date within such two hundred forty (240) day period, then Tenant may cancel this Lease on
forty-five (45) days’ prior written notice to Landlord provided however, if the the Demised Premises are substantially restored to the condition existing as of the Commencement Date within such forty-five (45) day period, then
Tenant’s notice of cancellation shall be null and void and this Lease shall continue in full force and effect. Further, if the Demised Premises is totally damaged by reason of fire or other casualty during the last 12 months of the term of this
Lease, Tenant shall have the right to cancel this Lease upon 45 days prior written notice to Landlord. 
 10. Eminent Domain: If the
whole or any part of the Demised Premises shall be acquired or condemned by eminent domain for any public or quasi public use or purpose, then and in that event, the term of this lease shall cease and terminate from the date of title vesting in such
proceeding and Tenant shall have no claim for the value of any unexpired term of said lease. 
 Nothing contained in this Article 10 hereof
shall prohibit Tenant from making a separate claim with the condemning authority for (a) the value of the property owned by Tenant, and (b) any moving expenses incurred by Tenant as a result of such condemnation provided, however, that
such claims shall not reduce or adversely affect the amount of Landlord’s award or Landlord’s claim. 
 11. Assignment,
Mortgage, Etc.: Tenant, for itself, its heirs, distributees, executors, administrators, legal representatives, successors and assigns, expressly covenants that it shall not assign, mortgage or encumber this Lease, nor underlet, or suffer or
permit the Demised Premises or any part thereof to be used by others without the prior written consent of 

 
Landlord in each instance Transfer of the majority of the stock of a corporate Tenant shall be deemed an assignment of this lease. If this lease be assigned,
or if the Demised Premises or any part thereof be underlet or occupied by anybody other than Tenant, Landlord may, after default by Tenant, collect rent from the assignee, under-tenant or occupant, and apply the net amount collected to the rent
herein reserved, but no such assignment, underletting, occupancy or collection shall be deemed a waiver of this covenant, or the acceptance of the assignee, under-tenant or occupant as tenant, or a release of Tenant from the further performance by
Tenant of covenants on the part of Tenant herein contained. The consent by Landlord to an assignment or underletting shall not in anyway be constructed to relieve Tenant from obtaining the express consent in writing of Landlord to any further
assignment or underletting. 
 12. Electric Current: Tenant covenants and agrees that at all times its use of electric current shall
not exceed the capacity of existing feeders to the Building or the switchgear or risers or wiring installation and Tenant may not use any electrical equipment which, in Landlord’s opinion will overload such installations or interfere with the
use thereof by other tenants of the Building. The change at any time of the character of electric service shall in no manner make Landlord liable or responsible to Tenant, for any loss, damages or expenses which Tenant may sustain. 
 13. Access to Premises: Landlord or Landlord’s agents shall have the right (but shall not be obligated) to enter the Demised Premises in any
emergency at any time, and, at other reasonable times, to examine the same and to make such repairs, replacements and improvements as Landlord may deem necessary and reasonably desirable to any portion of the Building or which Landlord may elect to
perform in the Demised Premises after Tenant’s failure to make repairs or perform any work which Tenant is obligated to perform under this lease, or for the purpose of complying with laws, regulations and other directions of governmental
authorities. Landlord shall perform any work using all reasonable efforts to minimize interference and interruption with Tenant’s occupancy and the conduct of its business in the Demised Premises. Tenant shall permit Landlord to use and
maintain and replace pipes and conduits in and through the Demised Premises and to erect new pipes and conduits therein. Landlord may, during the progress of any work in the Demised Premises, take all necessary materials and equipment into the
Demised Premises without the same constituting an actual or constructive eviction nor shall the Tenant be entitled to any abatement of rent while such work is in progress nor to any damages by reason of loss or interruption of business or otherwise.
Throughout the term hereof, Landlord shall have the right to enter the Demised Premises at reasonable hours for the purpose of showing the same to prospective purchasers or mortgagees of the Building, and during the last six (6) months of the
term for the purpose of showing the same to prospective tenants and may, during said six (6) months period, place upon the Building the usual notices “To Let” and “For Sale” which notices Tenant shall permit to remain
thereon without molestation. Whenever Landlord is permitted access to the Demised Premises pursuant to the provisions of this Lease, Landlord agrees (except in the event of an emergency) that it will (i) use commercially reasonable efforts to
schedule such access so as not to unreasonably interfere with the operation of Tenant’s business (provided that in no event will Landlord be required to employ labor at overtime rates), (ii) discuss the work plan and supervision with
Tenant, and (iii) take reasonable precautions to safeguard Tenant’s equipment. If Tenant is not present to open and permit an entry into the Demised Premises, Landlord or Landlord’s agents may enter the same whenever such entry may be
necessary or permissible by master key or forcibly and provided reasonable care is exercised to safeguard Tenant’s property, such entry shall not render Landlord or its agents liable therefor, nor in any event shall the obligations of Tenant
hereunder be affected. If during the last month of the term Tenant shall have removed all or substantially all of Tenant’s property therefrom, Landlord may immediately enter, alter, renovate or redecorate the Demised Premises without limitation
or abatement of rent, or incurring liability to Tenant for any compensation and such act shall have no effect on this lease or Tenant’s obligations hereunder. 
 Anything to the contrary in this Lease notwithstanding, if due to any work or installation performed by Landlord under the Lease or failure by Landlord to perform its obligations under the Lease or provide a service
Landlord has agreed to provide (together an “Interruption Condition”), (i) Tenant shall be unable for at least ten (10) consecutive business days to operate its business in the Demised Premises in the same manner as such business
was operated prior to the occurrence of the Interruption Condition, (ii) Tenant does not operate its business in the Demised Premises in the same manner as such business was operated prior to the occurrence of the Interruption Condition during
the entire period of time rent is reduced (as provided below) (iii) such interruption shall occur during Tenant’s business hours, and (iv) Tenant shall have, on the first day Tenant was unable to operate its business as aforesaid,
notified Landlord (in writing in accordance with Article 28 hereof) of the same, then the Fixed Rent and the Additional Rent shall be reduced on a per diem basis, in the proportion in which the area of the part of the Demised Premises which is
unusable or inoperable (as reasonably determined by Landlord) bears to the total area of the Demised Premises, for each day subsequent to the date which is ten (10) consecutive business days after the date Landlord receives the notice required

 
under sub-paragraph (iv) above that such portion of the Demised Premises remains unusable, as provided above until the date the Interruption Condition
is remedied, as specified by Landlord. 
 14. Vault, Vault Space, Area: No Vaults, vault space or area, whether or not enclosed or
covered, not within the property line of the Building is leased hereunder, anything contained in or indicated on any sketch, blue print or plan, or anything contained elsewhere in this lease to the contrary notwithstanding. Landlord makes no
representation as to the location of the property line of the Building. All vaults and vault space and all such areas not within the property line of the Building, which Tenant may be permitted to use and/or occupy, is to be used and/or occupied
under a revocable license, and if any such license be revoked or if the amount of such space or area be diminished or required by any federal, state or municipal authority or public utility, Landlord shall not be subject to any liability nor shall
Tenant be entitled to any compensation or diminution or abatement of rent, nor shall such revocation, diminution or requisition be deemed an actual or constructive eviction. Any tax, fee or charge of municipal authorities for such vault or area
shall be paid Tenant, if used by Tenant, whether or not specifically leased hereunder. 
 15. Occupancy: Tenant will not at any time
use or occupy the Demised Premises in violation of the Certificate of Occupancy issued for the Building. Tenant has inspected the Demised Premises and the improvements located therein, as further delineated on Exhibit D attached hereto
(“Improvements”), and accepts the Demised Premises and Improvements in its as is condition as of the Commencement Date; provided, however, Landlord will install a demising wall and relocate (within 60 days from the date hereof) an existing
preaction system into the Demised Premises. Landlord shall be responsible for removing and satisfying any liens which may exist now or in the future (to the extent not imposed as a result of Tenant’s actions or inactions) on any of the
Improvements so that Tenant’s use of such Improvements is undisturbed during the Lease Term. In any event, Landlord makes no representation as to the condition of the Demised Premises and the Improvements and Tenant agrees to accept the same
subject to violations, whether or not of record, provided Tenant will not be liable for any such violations existing as of the Commencement Date. 
 16. Bankruptcy: (a) Anything elsewhere in this lease to the contrary notwithstanding, this lease may be cancelled by Landlord by sending of a written notice to Tenant within a reasonable time after the happening of any one or
more of the following events: (1) the commencement of a case in bankruptcy or under the laws of any state naming Tenant as the debtor, which, in the case of an involuntary bankruptcy, is not dismissed within sixty (60) days after the
commencement thereof or (2) the making by Tenant of an assignment or any other arrangement for the benefit of creditors under any state statute. Neither Tenant nor any person claiming through or under Tenant, or by reason of any statute or
order of court, shall thereafter be entitled to possession of the Demised Premises but shall forthwith quit and surrender the Demised Premises. If this lease shall be assigned in accordance with its terms, the provisions of this Article 16 shall be
applicable only to the party then owning Tenant’s interest in this lease. 
 (b) It is stipulated and agreed that in the event of the
termination of this lease pursuant to (a) hereof, Landlord shall forthwith, notwithstanding any other provisions of this lease to the contrary, be entitled to recover from Tenant as and for liquidated damages an amount equal to the difference
between the rental reserved hereunder for the unexpired portion of the term and the fair and reasonable rental value of the Demised Premises for the same period. In the computation of such damages the difference between any installment of rent
becoming due hereunder after the date of termination and the fair and reasonable rental value of the Demised Premises for the period for which such installment was payable shall be discounted to the date of termination at the rate of four percent
(4%) per annum. If the Demised Premises or any part thereof be relet by Landlord for the unexpired term of said lease, or any part thereof, before presentation of proof of such liquidated damages to any court, commission or tribunal, the amount
of rent reserved upon such reletting shall be deemed to be the fair and reasonable rental value for the part or the whole of the Demised Premises so re-let during the term of the re-letting. Nothing herein contained shall limit or prejudice the
right of the Landlord to prove for and obtain as liquidated damages by reason of such termination, an amount equal to the maximum allowed by any statute or rule of law in effect at the time when, and governing the proceedings in which, such damages
are to be proved, whether or not such amount be greater, equal to, or less than the amount of the difference referred to above. 
 17.
Default: A. If Tenant defaults in fulfilling any of the covenants of this lease other than the covenants for the payment of rent or additional rent; or if the Demised Premises becomes vacant or deserted; or if any execution or attachment
shall be issued against Tenant or any of Tenant’s property whereupon the Demised Premises shall be taken or occupied by someone other than Tenant; or if this lease be rejected under Section 235 of Title 11 of the U.S. Code (bankruptcy
code) or if Tenant shall fail to commence its operations in the Demised Premises within 90 days after the Commencement Date, then, in any one or more of such events, upon Landlord serving a written twenty (20) days notice upon Tenant specifying
the 

 
nature of said default and upon the expiration of said twenty (20) days if Tenant shall have failed to comply with or remedy such default, or if the
said default or omission complained of shall be of a nature that the same cannot be completely cured or remedied within said twenty (20) day period, and if Tenant shall not have diligently commenced curing such default within such twenty
(20) day period, and shall not thereafter with reasonable diligence and in good faith, proceed to remedy or cure such default, then Landlord may serve a written three (3) days’ notice of cancellation of this lease upon Tenant, and
upon the expiration of said three (3) days this lease and the term thereunder shall end and expire as fully and completely as if the expiration of such three (3) day period were the day herein definitely fixed for the end and expiration of
this lease and the term thereof and Tenant shall then quit and surrender the Demised Premises to Landlord but Tenant shall remain liable as hereinafter provided. 
 B. If the notice provided for in (A) hereof shall have been given and the term shall expire as aforesaid; or if Tenant shall default in the payment of any item of rent reserved herein or any item of additional
rent herein mentioned or any part of either or in making any other payment herein required after five (5) days written notice, provided Landlord shall not be required to deliver such notice more than once in any twelve (12) consecutive
month period: then and in any of such events, Landlord may dispossess Tenant by summary proceedings or otherwise, and the legal representative of Tenant or other occupant of the Demised Premises and remove their effects and hold the Demised Premises
as if this lease had not been made, and Tenant hereby waives the service of notice of intention to re-enter or to institute legal proceedings to that end. If Tenant shall make default hereunder prior to the date fixed as the commencement of any
renewal or extension of this lease, Landlord may cancel and terminate such renewal or extension agreement by written notice. 
 18.
Remedies of Landlord and Waiver of Redemption: In case of any such default, re-entry, expiration and/or dispossess by summary proceedings or otherwise, (a) the rent, and additional rent, shall become due thereupon and be paid up to the
time of such re-entry, dispossess and/or expiration, (b) Landlord may re-let the Demised Premises or any part or parts thereof, either in the name of Landlord or otherwise, for a term or terms, which may at Landlord’s option be less than
or exceed the period which would otherwise have constituted the balance of the term of this lease and may grant concessions or free rent or charge a higher rental than that in this lease, (c) Tenant or the legal representatives of Tenant shall
also pay Landlord as liquidated damages for the failure of Tenant to observe and perform said Tenant’s covenants herein contained, any deficiency between the rent hereby reserved and or covenanted to be paid and the net amount, if any, of the
rents collected on account of the subsequent lease or leases of the Demised Premises for each month of the period which would otherwise have constituted the balance of the term of this lease. The failure of Landlord to re-let the Demised Premises or
any part or parts thereof shall not release or affect Tenant’s liability for damages hereunder. In computing such liquidated damages there shall be added to the said deficiency such expenses as Landlord may incur in connection with re-letting,
such as legal expenses, attorneys’ fees, brokerage, advertising and for keeping the Demised Premises in good order or for preparing the same for re-letting. Any such liquidated damages shall be paid in monthly installments by Tenant on the rent
day specified in this lease and any suit brought to collect the amount of the deficiency for any month shall not prejudice in any way the rights of Landlord to collect the deficiency for any subsequent month by a similar proceeding. Landlord, in
putting the Demised Premises in good order or preparing the same for re-rental may, at Landlord’s option, make such alterations, repairs, replacements, and/or decorations in the Demised Premises as Landlord, in Landlord’s sole judgment,
considers advisable and necessary for the purpose of re-letting the Demised Premises, and the making of such alterations, repairs, replacements, and/or decorations shall not operate or be construed to release Tenant from liability hereunder as
aforesaid. Landlord shall in no event be liable in any way whatsoever for failure to re-let the Demised Premises, or in the event that the Demised Premises are re-let, for failure to collect the rent thereof under such re-letting, and in no event
shall Tenant be entitled to receive any excess, if any, of such net rents collected over the sums payable by Tenant to Landlord hereunder. In the event of a breach or threatened breach by Tenant of any of the covenants or provisions hereof, Landlord
shall have the right of injunction and the right to invoke any remedy allowed at law or in equity as if re-entry, summary proceedings and other remedies were not herein provided for. Mention in this lease of any particular remedy, shall not preclude
Landlord from any other remedy, in law or in equity. Tenant hereby expressly waives any and all rights of redemption granted by or under any present or future laws. 
 In addition to the rights granted Landlord hereunder, in the event of Landlord’s giving notice of termination of this Lease, in accordance herewith, Landlord shall also be entitled to an award for liquidated
damages (in addition to the damages stated above) in an amount which, at the time of such termination, is equal to the excess, if any, of the installments of Fixed Rent and the aggregate of all sums payable hereunder as additional rent reserved
hereunder for the period which would otherwise have constituted the unexpired portion of the then current Term of this Lease, plus the value of all other considerations to be paid or performed by Tenant during such period, over the fair rental value
of the Demised Premises, as of the date of such termination, for such unexpired portion of the then current Term of this Lease. If the Demised 

 
Premises, or any part thereof be relet by Landlord for the unexpired Term or any part thereof before presentation of proof of such liquidated damages to any
court, commission or tribunal, the amount of rent reserved upon such reletting shall be deemed to be the fair rental value for the part or the whole of the Premises so relet during the term of the reletting. Prior to Tenant’s full payment of
any liquidated damages awarded to Landlord, Tenant shall continue to pay punctually to Landlord all Fixed Rent and Additional Rent to the same extent and at the same time as if this Lease, had not been terminated. If Landlord shall elect to re-enter
and take possession without terminating this Lease, Landlord shall have the right at any time thereafter to terminate this Lease for such previous default, whereupon the provisions of this subsection with respect to termination will thereafter
apply. 
 All legal fees and expenses incurred by Landlord in enforcing its rights under this Lease shall be deemed Additional Rent and due
and payable by Tenant upon demand. If Landlord brings any summary action for dispossession of Tenant for failure to pay rent, Landlord’s reasonable attorney’s fees and legal expenses shall be added to and included as part of the sums due
and owing by Tenant with respect to the periods in default. 
 The receipt and acceptance by Landlord of Fixed Rent or additional rent with
knowledge of default by Tenant of any of Tenant’s obligations under this Lease shall not be deemed a waiver by Landlord of such default. Nothing contained in this Lease shall limit or prejudice the right of Landlord to prove for and obtain in
proceedings for bankruptcy or insolvency an amount equal to the maximum allowed by any statute or rule of law in effect at the time when, and governing the proceedings in which, the damages are to be proved, whether or not the amount be greater
than, equal to, or less than the amount of the loss or damages referred to above. No waiver by Landlord of any default by Tenant in any covenant, agreement or obligation under this Lease shall operate to waive or affect any subsequent default in any
covenant, agreement or obligation hereunder, nor shall any forbearance by Landlord to enforce a right or remedy upon any such default be a waiver of any of its rights and remedies with respect to such or any subsequent default or in any other manner
operate to the prejudice of Landlord. 
 19. Fees and Expenses: If Tenant shall default in the observance or performance of any term
or covenant on Tenant’s part to be observed or performed under or by virtue of any of the terms or provisions in any Article of this lease, then, unless otherwise provided elsewhere in this lease, Landlord may, immediately or any time
thereafter and without notice, perform the obligations of Tenant hereunder. If Landlord, in connection with the foregoing or in connection with any default by Tenant in the covenant to pay rent hereunder, makes any expenditures or incurs any
obligations for the payment of money, including but not limited to attorney’s fees, in instituting, prosecuting or defending any action or proceedings, then Tenant will reimburse Landlord for such sums so paid or obligations incurred with
interest and costs. The foregoing expenses incurred by reason of Tenant’s default shall be deemed to be additional rent hereunder and shall be paid by Tenant to Landlord within five (5) days after rendition of any bill or statement to
Tenant therefor. If Tenant’s lease term shall have expired at the time of making of such expenditures or incurring of such obligations, such sums shall be recoverable by Landlord as damages. 
 20. Building Alterations and Management: Provided same does not materially and adversely impede access to the Demised Premises, Landlord shall
have the right at any time without the same constituting an eviction and without incurring liability to Tenant therefor to run pipes and conduits through the Demised Premises and other building areas, make other repairs and to change the arrangement
and or location of public entrances, passageways, doors, doorways, corridors, elevators, stairs, toilets or other public parts of the Building and to change the name, number or designation by which the Building may be known. There shall be no
allowance to Tenant for diminution of rental value and no liability on the part of Landlord by reason of inconvenience, annoyance or injury to business arising from Landlord or other Tenant making any repairs in the Building or any such alterations,
additions and improvements. Furthermore, Tenant shall not have any claim against Landlord by reason of Landlord’s imposition of any controls of the manner of access to the Building by Tenant’s invitees as the Landlord may deem necessary
for the security of the Building and its occupants. 
 21. No Representations by Landlord: Neither Landlord nor Landlord’s agents
have made any representations or promises with respect to the physical condition of the Building, the land upon which it is erected or the Demised Premises, the rents, leases, expenses of operation or any other matter or thing affecting or related
to the Demised Premises or the Building except as herein expressly set forth and no rights, easements or licenses are acquired by Tenant by implication or otherwise except as expressly set forth in the provisions of this lease. Tenant has inspected
the Building and the Demised Premises and is thoroughly acquainted with their condition and agrees to take the same “as is” on the date possession is tendered and acknowledges that the taking of possession of the Demised Premises by Tenant
shall be conclusive evidence that the said Demised Premises and the Building of which the same form a part were in good and satisfactory condition at the time such possession was so taken. All understandings and agreements heretofore made between
the parties hereto are 

 
merged in this contract, which alone fully and completely expresses the agreement between Landlord and Tenant and any executory agreement hereafter made
shall be ineffective to change, modify, discharge or effect an abandonment of it in whole or in 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. 
 22. End of Term: Upon the expiration or sooner termination of the term of this lease, Tenant shall quit and
surrender to Landlord the Demised Premises, broom clean, in good order and condition, ordinary wear and damages which Tenant is not required to repair as provided elsewhere in this lease excepted, and shall quit and surrender to Landlord the
Improvements in working order, at least in the condition existing as the Commencement Date. Tenant shall remove all of its personal property from the Demised Premises. Tenant’s obligation to observe or perform its covenant shall survive the
expiration or other termination of its lease. If the last day of the term of this Lease or any renewal thereof, falls on Sunday, this lease shall expire at noon on the preceding Saturday unless it be a legal holiday in which case it shall expire at
noon on the preceding business day. 
 23. Quiet Enjoyment: Landlord covenants and agrees with Tenant that upon Tenant paying the rent
and additional rent and observing and performing all the terms, covenants and conditions, on Tenant’s part to be observed and performed, Tenant may peaceably and quietly enjoy the Demised Premises hereby demised, subject, nevertheless, to the
terms and conditions of this lease. 
 24. Failure to Give Possession: If Landlord is unable to give possession of the Demised
Premises on the date of the commencement of the term hereof, because of the holding-over or retention of possession of any tenant, undertenant or occupants, or if Landlord has not completed any work required to be performed by Landlord, or for any
other reason, Landlord shall not be subject to any liability for failure to give possession on said date and the validity of the lease shall not be impaired under such circumstances, nor shall the same be construed in any manner to extend the term
of this lease, but the rent payable hereunder shall be abated until after Landlord shall have given Tenant notice that the Demised Premises are substantially ready for Tenant’s occupancy. If permission is given to Tenant to enter into the
possession of the Demised Premises or to occupy any space in the Building other than the Demised Premises prior to the date specified as the commencement of the term of this lease, Tenant covenants and agrees that such occupancy shall be deemed to
be under all the terms, covenants, conditions and provisions of this lease, except as to the covenant to pay rent. The provisions of this Article are intended to constitute “an express provision to the contrary” within the meaning of
Section 223-a of the New York Real Property Law. 
 25. No Waiver: The failure of Landlord to seek redress for violation of, or
to insist upon the strict performance of any covenant or condition of this lease or of any of the Rules or Regulations, set forth or hereafter adopted by Landlord, 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 and no provision 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
earliest stipulated rent, nor shall any endorsement or statement of any check, any letter accompanying any check or payment of 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. All checks tendered to Landlord as and for the rent of the Demised Premises shall be deemed payments for the account of Tenant. Acceptance
by Landlord of rent from anyone other that Tenant shall not be deemed to operate as an attornment to Landlord by the payor of such rent or as a consent by Landlord to an assignment or subletting by Tenant of the Demised Premises to such payor, or as
a modification of the provisions of this lease. No act or thing done by Landlord or Landlord’s agents during the term hereby demised shall be deemed an acceptance of a surrender of said Demised Premises and no agreement to accept such surrender
shall be valid unless in writing signed by Landlord. No employee of Landlord or Landlord’s agent shall have any power to accept the keys of said Demised Premises prior to termination of the lease and the delivery of keys to any such agent or
employee shall not operate as a termination of the lease or a surrender of the Demised Premises. 
 26. Waiver of Trial by Jury: It is
mutually agreed by and between Landlord and Tenant that the respective parties hereto shall and they hereby do waive trial by jury in any action, proceeding or counterclaim brought by either of the parties hereto against the other (except for
personal injury or property damage) on any matters whatsoever arising out of or in any way connected with this lease, the relationship of Landlord and Tenant, Tenant’s use of or occupancy of the Demised Premises, and any emergency statutory or
any other statutory remedy. It is further mutually agreed that in the event Landlord commences any summary proceeding for possession of the Demised Premises, Tenant will not interpose any counterclaim 

 
of whatever nature or description in any such proceeding, except for mandatory counterclaims which would otherwise be waived. 
 27. Inability to Perform: This Lease and the obligation of Tenant to pay rent hereunder and perform all of the other covenants and agreements
hereunder on part of Tenant to be performed shall in no manner be affected, impaired or excused because Landlord is unable to fulfill any of its obligations under this lease or 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 repair, additions, alterations 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
strike or labor troubles or any cause whatsoever beyond Landlord’s sole control including, but not limited to, government preemption in connection with a National Emergency or by reason of any rule, order or regulation of any department or
subdivision thereof of any government agency or by reason of the condition of supply and demand which have been or are affected by war or other emergency. 
 28. Notices: Every notice, demand, consent, approval, request or other communication (collectively, “notices”) which may be or is required to be given under this Lease or by law shall be in writing
and shall be sent by recognized national overnight delivery service, personal delivery or by United States certified or registered mail, postage prepaid, return receipt requested and shall be addressed as follows:

 29.
Services Provided By Landlord: As long as Tenant is not in default under any of the covenants of this lease, Landlord shall provide the following services, except as otherwise provided herein: 
 A. Elevator Service. 
  

	 	(i)	Passenger Elevator Service. Landlord shall provide necessary passenger elevator facilities twenty-four (24) hours a day, three hundred, sixty five (365) days a year.

  

	 	(ii)	Freight Elevator Service. Landlord shall provide freight elevator service to the Demised Premises on a first-come, first-served basis (i.e., no advance scheduling) on business days
from 8:00 a.m. to 4:30 p.m. Freight elevator service shall, provided same is available, be provided on a reserved basis at all other times, upon the payment of Landlord’s then established charges therefor which shall constitute additional rent
hereunder. Notwithstanding the above, in the event of an emergency situation, Landlord will exercise commercially reasonable efforts to make available the freight elevator for Tenant’s use, provided however Landlord shall not be required to
employ labor at overtime rates. 

 B. Cleaning Services. 
  

	 	(i)	Tenant shall cause all areas of the Demised Premises, including the executive and administrative portions thereof to be cleaned at its own expense by a cleaning contractor
reasonably approved by Landlord. 

  

	 	(ii)	Tenant, at its expense, shall cause all portions of the Demised Premises to be exterminated against infestation by vermin, roaches or rodents regularly and, in addition, whenever
there shall be evidence of any infestation. 

  

	 	(iii)	Only Landlord or any one or more persons, firms or corporations authorized in writing by Landlord shall be permitted to act as maintenance contractor for any waxing, polishing,
cleaning and maintenance work in the Demised Premises. Nothing herein contained shall prohibit Tenant from performing such work for itself by use of its regular employees. Landlord may fix, in its absolute discretion, at any time and from time to
time, the hours during which and regulations under which such services are to be furnished. Landlord expressly reserves the right to act as or to designate, at any time and from time to time, an exclusive contractor for all or any one or more of
such services, provided that the quality thereof and the charges therefor are reasonably comparable to that of other contractors, and Landlord expressly reserves the right to exclude from the Building any person, firm or corporation attempting to
furnish any of such services. 

 C. Water. Landlord shall provide water for ordinary lavatory and drinking purposes
only, but if Tenant uses or consumes water for any other purposes or in unusual quantities (i.e., including, but not limited to, use in connection with its own HVAC system), Landlord may install a water meter (or meters to measure both hot and cold
water usage in the event Landlord provides both hot and cold water) at Tenant’s expense which Tenant shall thereafter maintain at Tenant’s expense in good working order and repair to register such water consumption and Tenant shall pay for
water consumed as shown on said meter(s), and Landlord’s standard charges for water and Landlord’s fee equal to three (3%) of such charge, representing administrative and overhead costs incurred by Landlord as additional rent as and
when bills are rendered. In the event such bills are not paid within ten (10) days after the same are rendered, Landlord may without further notice, discontinue the service of water to the Demised Premises without releasing Tenant from any
liability for any damage loss or sustained by Tenant as a result of such discontinuance. 
 D. Heat. See Article 54. 
 E. Landlord reserves the right, without same constituting an actual or constructive eviction or entitling Tenant to any abatement and/or diminution of
fixed rent and/or additional rent, to stop services of the heating, elevators, plumbing, air-conditioning, power systems or cleaning or other services, if any, when necessary by reason of accident or for repairs, alterations, replacements or
improvements necessary or desirable in the judgment of Landlord for as long as may be reasonably required by reason thereof. If the Building of which the Demised Premises are a part supplies manually-operated elevator service, Landlord at any time
may substitute automatic-control elevator service and upon ten days’ written notice to Tenant, proceed with alterations necessary therefor without in any manner affecting this lease or the obligation of Tenant hereunder. The same shall be done
with a minimum of inconvenience to Tenant and Landlord shall pursue the alteration with due diligence. 
 30. Captions: 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 nor the intent of any provision thereof. 
 31. Definitions: The term “Landlord” as used in this lease means only the Landlord of the fee or of the leasehold of the
Building, or the mortgagee in possession, for the time being of the land and Building (or the Landlord of a lease of the Building or of the land and Building) of which the Demised Premises form a part, so that in the event of any sale or sales of
said land and Building or of said lease, or in the event of a lease of said Building, or of the land and Building, Landlord shall be and hereby is entirely freed and relieved of all covenants and obligations of Landlord hereunder and it shall be
deemed and construed without further agreement between the parties or their successors in interest, or between the parties and the purchaser, at any such sale, or the said lessee of the Building, or of the land and Building, that the purchaser or
the lessee of the Building has assumed and agreed to carry out any and all covenants and obligations of Landlord hereunder. The words “re-enter” and “re-entry” as used in this lease are not restricted to their technical legal
meaning. The term “business days” as used in this lease, shall exclude Saturdays, Sundays and all days observed by the State or Federal Government as legal holidays and those designated as holidays by the applicable Building service union
employees service contract or by the applicable Operating Engineers contract with respect to HVAC service. 

 32. Estoppel Certificate: Tenant shall execute, acknowledge and deliver to Landlord, within
ten (10) business days after Landlord’s request, a certificate stating: (a) that this lease is unmodified and in full force and effect (or, if there have been modifications, that this lease is in full force and effect, as modified,
and identifying the modifications); (b) the commencement and expiration dates of the term of this lease; (c) the dates through which fixed rent and additional rent have been paid; (d) whether or not there is any existing default by
Landlord or Tenant with respect to which a notice of default has been delivered, and if there is any such default, specifying the nature and extent thereof; (e) that this lease is subordinate to any existing or future mortgage placed by
Landlord on the Building; and (f) whether or not there are any setoffs, defenses or counterclaims against the enforcement of any of the agreements, terms, covenants or conditions of this lease to be paid, complied with or performed by Tenant.
Any such certificate may be relied upon by Landlord and any mortgagee, purchaser or other person with whom Landlord may deal. In the event that Tenant fails to deliver the certificate required under this Article 32, same shall be deemed a default
hereunder. Tenant’s only liability under this Article 32 is to be estopped from any claim contrary to the certificate executed therein. 
 33. Rules and Regulations: Tenant and Tenant’s servants, employees, agents, visitors, and licensees shall observe faithfully, and comply strictly with, the Rules and Regulations annexed hereto and made a part hereof as
Exhibit C and such other and further reasonable Rules and Regulations as Landlord or Landlord’s agents may from time to time adopt. Notice of additional rules or regulations shall be given in writing to Tenant in accordance with the provisions
of Article 28 of this Lease. In case Tenant disputes the reasonableness of any additional Rule or Regulation hereafter made or adopted by Landlord or Landlord’s agents, the parties hereto agree to submit the question of the reasonableness of
such Rule or Regulation for decision to the New York office of the American Arbitration Association, whose determination shall be final and conclusive upon the parties hereto. The right to dispute the reasonableness of any additional Rule or
Regulation upon Tenant’s part shall be deemed waived unless the same shall be asserted by service of a notice, in writing upon Landlord within ten (10) days after the giving of notice thereof. 
 34. Security: 
 A. Tenant
shall, upon execution of this lease, deposit with Landlord the sum of Two Hundred Thousand ($200,00.00) security (“Security”) for the faithful performance and observance by Tenant of the terms, provisions and conditions of this lease; it
is agreed that in the event Tenant defaults in respect of any of the terms, provisions and conditions of this lease, including, but not limited to, the payment of rent and additional rent, and fails to cure the same within any applicable grace
and/or notice periods, then, Landlord may use, apply or retain the whole or any part of the security so deposited to the extent required for the payment of any rent and additional rent or any other sum as to which tenant is in default or for any sum
which Landlord may expend or may be required to expend by reason of Tenant’s default in respect of any of the terms, covenants and conditions of this lease, including but not limited to, any damages or deficiency in the re-letting of the
Demised Premises, whether such damages or deficiency accrued before or after summary proceedings or other re-entry by Landlord. If Landlord applies or retains all or any portion of the Security Tenant shall immediately upon Landlord’s demand
restore the amount so applied so that Landlord has on deposit the full amount of Security. In the event that Tenant shall fully and faithfully comply with all of the terms, provisions, covenants and conditions of this lease, the security shall be
promptly returned to Tenant. In the event of a sale of the land and Building or leasing of the Building, of which the Demised Premises form a part, Landlord shall have the right to transfer the security to the vendee or lessee and Landlord shall
thereupon be released by Tenant from all liability for the return of such security; and Tenant agrees to look to the new Landlord solely for the return of said security, and it is agreed that the provisions hereof shall apply to every transfer or
assignment made of the security to a new Landlord. Tenant further covenants that it will not assign or encumber or attempt to assign or encumber the monies deposited herein as security and that neither Landlord nor its successors or assigns shall be
bound by any such assignment, encumbrance, attempted assignment or attempted encumbrance. 
 B. In lieu of the cash security provided for
above, Tenant may deliver to Landlord, an irrevocable, clean, commercial letter of credit in the amount of $200,000.00 DOLLARS and 00/100 (the “Letter”), issued by a bank which is authorized, or a bank that has a corresponding banking
relationship with a bank which is authorized, by the State of New York to conduct banking business in New York State and is a member of the New York Clearing House Association, which shall permit Landlord (a) to draw thereon up to the full
amount of the credit evidenced thereby in the event of any default by Tenant in the terms, provisions, covenants or conditions of this Lease beyond applicable grace, notice and/or cure periods or (b) to draw the full amount thereof to be held
as cash security pursuant to Article 34 hereof if for any reason the Letter is not renewed within forty five (45) days prior to its expiration date. The Letter (and each renewal thereof) shall (i) be for a term of not less than one
(1) year (except that the last Letter shall be for a term expiring forty five (45) days after the Expiration Date), (ii) expressly provide for the issuing bank to notify Landlord in writing not less than thirty (30) days prior to
its expiration as 

 
to its renewal or non-renewal, as the case may be, and (iii) if not so renewed each year (or later period of expiration) shall be immediately available
for Landlord to draw up to the full amount of such credit (to be held as cash security). Not less than forty-five (45) days prior to the expiration date of each Letter (and every renewal thereof), Tenant shall deliver to Landlord a renewal or
new Letter subject to all of the conditions aforesaid. Failure by Tenant to comply with the provisions of this Article beyond applicable grace, notice and/or cure periods shall be deemed a material default hereunder entitling Landlord to exercise
any and all remedies as provided in this Lease for default in the payment of fixed rent and, to draw on the existing Letter up to its full amount. 
 Provided Tenant is not then and has not been (during the first five (5) Lease Years of the term) in default hereunder and provided Tenant has a net operating income of at least $3,500,000 during the fifth Lease Year, (which shall be
documented to Landlord’s reasonable satisfaction, including but not limited to delivery of a certified statement from a nationally recognized certified public accountant) then commencing on the fifth anniversary of the Commencement Date of this
Lease, the security shall be reduced by Eighty Nine Thousand Two Hundred Forty Seven Dollars ($89,247.00) to One Hundred Ten Thousand Seven Hundred and Fifty Three Dollars ($110,753.00), which amount shall remain the security for the balance of the
term of the Lease. 
 35. Adjacent Excavation - Shoring: If an excavation shall be made upon land adjacent to the Demised
Premises, or shall be authorized to be made, Tenant shall afford to the person causing or authorized to cause such excavation, license to enter upon the demises Demised Premises for the purpose of doing such work as said person shall deem necessary
to preserve the wall or the Building of which Demised Premises form a part from injury or damage and to support the same by proper foundations without any claim for damages or indemnity against Landlord, or diminution or abatement of rent.

 36. Successors and Assigns: The covenants, conditions and agreements contained in this lease shall bind and inure to the
benefit of Landlord and Tenant and their respective heirs, distributees, executors, administrators, successors, and except as otherwise provided in this lease, their assigns.

 39. ESCALATION FOR INCREASE IN REAL ESTATE TAXES: 
 A. As used herein: 
 1. “Taxes”
shall mean real estate taxes payable (adjusted after protest or litigation, if any) for any part of the term of this lease, on the Building and/or the land (the “Land”), (i) any taxes which shall be levied in lieu of any such taxes or
which shall be levied on the gross rentals of the Building and/or the Land and (ii) any special assessments against the Building and/or the Land which shall be required to be paid during the fiscal year in respect to which taxes are being
determined. 
 2. “Tax Year” shall mean each period of twelve (12) months, commencing on the first day of July of each such
period, in which occurs any part of the term of this Lease or such other period of twelve (12) months occurring during the term of this Lease as hereafter may be duly adopted as the fiscal year for real estate tax purposes of the City of New
York. 
 3. “Base Tax” shall mean the Taxes for the fiscal tax year commencing July 1, 2004 and ending June 30, 2005 (the
“Base Tax Year”). 
 4. “Tenant’s Proportionate Share” shall mean three and four hundredths (3.04%) percent.

 B. If the Taxes for any Tax Year shall be greater than the Base Tax, then Tenant shall pay as additional rent for such Tax Year, a sum
equal to Tenant’s Proportionate Share of the amount by which the Taxes for such Tax Year are greater than the Base Tax (which amount 

 
is hereinafter called the “Tax Payment”). Should this Lease commence or terminate prior to the expiration of a Tax Year, such Tax Payment shall be
prorated to, and shall be payable on, or as and when ascertained after, the Commencement Date or the Expiration Date as the case may be. Tenant’s obligation to pay such additional rent and Landlord’s obligation to refund pursuant to
Paragraph C below, as the case may be, shall survive the termination of this Lease. If the Taxes for any Tax Year subsequent to the Base Tax Year, or an installment thereof, shall be reduced before such Taxes or such installment shall be paid, the
amount of Landlord’s reasonable costs and expenses of obtaining such reduction (but not exceeding the amount of such reduction) shall be added to and be due and payable within ten (10) days after rendition of a statement by Landlord.
Payment of additional rent for any Tax Payment due from Tenant shall be made as and subject to the conditions hereinafter provided in this Article. 
 C. Only Landlord shall be eligible to institute proceedings to contest the Taxes or reduce the assessed valuation of the land and Building. Landlord shall be under no obligation to contest the Taxes or the assessed valuation of the Land and
the Building for any Tax Year and may settle any such contest on such terms as Landlord in its sole judgment considers proper. If Landlord shall receive a refund for any Tax Year for which a Tax Payment shall have been made by Tenant pursuant to
Paragraph B above, Landlord shall repay to Tenant, with reasonable promptness, Tenant’s Proportionate Share of such refund. If the assessment for the Base Tax Year shall be reduced from the comparative statement (as provided in Paragraph D
below) to Tenant with respect to a Tax Year, the amount of the Tax Payment shall be adjusted in accordance with such change and Tenant, on Landlord’s demand, shall pay any increase in additional rent resulting from such adjustment. 

D. Landlord shall furnish to Tenant, prior to the commencement of any Tax Year, a written statement setting forth the Tax Payment for such Tax Year.
Tenant shall pay to Landlord on the first day of each month during such Tax Year an amount equal to one-twelfth (1/12th) of the Tax Payment for such Tax Year. If, however, Landlord shall furnish any such statement for a Tax Year subsequent to
the commencement thereof, then (i) until the first day of the month following the month in which such statement is furnished to Tenant, Tenant shall pay to Landlord on the first day of each month an amount equal to the monthly sum payable by
Tenant to Landlord under this Paragraph in respect of the last month of the immediately preceding Tax Year; (ii) promptly after such statement is furnished to Tenant, Landlord shall give notice to Tenant stating whether the installments of the
Tax Payment previously made for such Tax Year were greater or less than the installments of the Tax Payment to be made for such Tax Year in accordance with such statement, and (a) if there shall be a deficiency, Tenant shall pay the amount
thereof within ten (10) days after demand therefor, or (b) if there shall have been an overpayment, Landlord shall promptly either refund to Tenant the amount thereof or permit Tenant to credit the amount thereof against subsequent
payments under this Article; and (iii) on the first day of the month following the month in which such statement is furnished to Tenant, and monthly thereafter throughout the remainder of such Tax Year, Tenant shall pay to Landlord an amount
equal to one-twelfth (1/12th) of the Tax Payment shown on such statement. 
 E. Landlord’s failure during the lease term to prepare
and deliver any tax statements or bills, or Landlord’s failure to make a demand under this Article or under any other provision of this Lease shall not in any way waive Landlord’s right to collect any such amounts due hereunder.
Tenant’s liability for the additional rent due under this Article shall survive the expiration or sooner termination of this Lease. 
 F. In no event shall any adjustment of Tax Payments hereunder result in a decrease in the fixed rent or additional rent payable pursuant to any other provision of the lease, it being agreed that the payment of additional rent under this
Article 39 is an obligation supplemental to Tenant’s obligation to pay fixed rent. 
 40. INTENTIONALLY OMITTED.

 41. FIXED RENT CREDIT: 
 Provided Tenant is not in default under the terms, covenants and conditions of this lease, Tenant
shall receive a credit against Fixed Rent, in the total amount of $241,102, which credit shall be applied as follows: (a) $25,579.75 per month for the 1st through 4th months of the term of this Lease and (b) $9,913.08
per month for the 5th through 18th months of the term of this Lease. Except for the Fixed Rent credit as herein provided, Tenant shall use and occupy the Demised Premises pursuant to all of the
other terms, covenants and conditions of this lease. 

 42. AMENDING ARTICLE 11: 
 Notwithstanding the provisions of Article 11, and in modification and amplification thereof: 
 A. Except as provided in paragraphs I and L hereof, if Tenant shall desire to assign this Lease or to sublet all or a portion of the Demised Premises,
Tenant shall submit to Landlord a written request for Landlord’s consent to such assignment or subletting, which request shall contain or be accompanied by the following information: (i) the name and address of the proposed assignee or
subtenant; (ii) a duplicate original or photocopy of the proposed assignment agreement or sublease or a true and correct photocopy of the offer from the proposed assignee or subtenant signed by such proposed assignee or subtenant;
(iii) the nature and character of the business of the proposed assignee or subtenant and its proposed use of the Demised Premises, which shall be limited to the use set forth in Article 2 hereof unless Landlord consents to any altered use which
Landlord may or may not consent to in its absolute discretion; and (iv) banking, financial and other credit information with respect to the proposed assignee or subtenant reasonably sufficient to enable Landlord to determine the financial
responsibility of the proposed assignee or subtenant. 
 Landlord shall then have the option to be exercised by written notice given to Tenant
within twenty (20) days after receipt of Tenant’s request for consent to require a surrender of the Demised Premises or portion thereof, upon the terms and conditions hereinafter provided. 
 B. If Landlord shall exercise its option to require a surrender of the Demised Premises or portion thereof as provided above, then upon the proposed rent
commencement date of the subletting specified in Tenant’s notice to Landlord, the Demised Premises or portion intended to be sublet, as the case may be, shall be surrendered to Landlord in accordance with the provisions of the Lease pertinent
to surrender, and this Lease shall cease and terminate on the rent commencement date of said proposed sublease insofar as the Demised Premises or portion thereof, as the case may be, with the same force and effect as though such proposed
commencement date were the Expiration Date. If only a portion of the Demised Premises is involved, the terms and conditions of the Lease shall remain in full force and effect, except that the Fixed Rent and additional rent shall be proportionately
reduced based upon the number of square feet of the portion of the Demised Premise surrendered. In addition, in the event that less than all of the Demised Premises is surrendered: 
  

	 	1.	Landlord shall cause to be constructed, at Landlord’s sole cost and expense, such alterations and connections as may be required in order to physically separate such
surrendered portion of the Demised Premises from the balance of the Demised Premises; and 

 At least thirty (30) days prior to the
proposed commencement date specified above, Landlord shall have free access to enter to the Demised Premises in order to complete the construction referred to in “1” above. Landlord shall perform such work using commercially reasonable
efforts to minimize interference with Tenant’s business and shall except in emergency instances, perform such work upon at least 24 hours advance written or verbal notice to Tenant and accompanied by a representative of Tenant provided however,
in no event shall Landlord be required to employ labor at overtime rates. 
 C. In lieu of effectuating a surrender as aforesaid, Landlord
shall have the option to sublet from Tenant the Demised Premises or any portion thereof (“Leaseback Area”), and if Landlord exercises said option Tenant shall be deemed to have subleased the Leaseback Area to Landlord
(“Backleasing” or “Backlease”) for the term (“Backlease Term”) of the proposed sublease referred to in Tenant’s notice to Landlord, at a sublease rent equal to the lesser of (on a per square foot basis)
(a) the fixed rent payable under this lease or (b) rent specified in the sublease proposed by Tenant. All other terms and conditions of this Lease shall remain applicable to the Leaseback Area, except such as by their nature or purport are
inapplicable or inappropriate to such Backleasing, or are inconsistent with the further provisions of the following subsections of this paragraph, which further provisions shall be deemed to be part of the terms, covenants, and conditions of such
Backleasing. 
 In addition, the following provisions shall be applicable to any Backleasing: 
 a) (i) Landlord shall have the unqualified and unrestricted right, without Tenant’s permission or consent, to underlet the Leaseback Area in whole or
in part to any person or entity, including Tenant’s proposed subtenant, for any period or periods of time not extending beyond one (1) day before the expiration of the Backlease Term, at such rentals and on such terms and conditions
(including any alterations required to render the Leaseback Area suitable for occupancy by an undertenant of Landlord) as Landlord shall determine. Landlord may underlet the Leaseback Area or parts thereof separately or in combinations, as Landlord
deems appropriate. The Backlease may be assigned by Landlord to any person, including Tenant’s 

 
proposed subtenant, without Tenant’s consent but such assignment shall not be effective unless the transferee executes and delivers to Tenant a written
agreement assuming all of Landlord’s obligations under the Backlease, and in such event Landlord shall continue to be fully responsible jointly and severally with such assignee for all of Landlord’s obligations under the Backlease.

 b) (ii) Tenant shall furnish to Landlord or its assignee or subtenant under the Backlease any consents or approvals requested under the
Backlease so long as (a) Landlord furnishes such consents or approvals to Tenant and, (b) Tenant incurs no expense by reason of any such consent or approval; and 
 c) (iii) Landlord and Tenant expressly negate any intention that any estate created by or under the Backlease shall be merged with any other estate held
by either of them. At the request of either party, Landlord and Tenant shall mutually execute, acknowledge, and deliver an instrument or instruments of sublease and/or assignment to confirm and separately set forth the rent, terms, conditions and
other provisions of the Backleasing or any Leaseback Area as may be appropriate. 
 D. If Landlord does not exercise any of its options
specified above, then Landlord’s consent to a subletting of all or a portion of the Demised Premises or an assignment of Tenant’s interest in this lease shall not be unreasonably withheld or delayed on further condition that: 

 

	 	1.	The proposed subtenant or assignee shall not be a school of any kind, or an employment or placement agency or governmental or quasi governmental agency, medical office or executive
recruitment office; 

  

	 	2.	The subletting or assignment shall be to a tenant whose occupancy will be in keeping with the dignity and character of the Building and the use and occupancy of the Demised Premises
in accordance with Article 2 hereof and whose occupancy will not be more objectionable or more hazardous than that of Tenant herein or impose any additional burden upon Landlord in the operation of the Building; 

  

	 	3.	No space shall be advertised or openly promoted to the general public utilizing the name of the Landlord or any principal or partner thereof, or stating or otherwise characterizing
a rental rate; 

  

	 	4.	The proposed sublessee or assignee shall not be an occupant of any space in the Building or a party who dealt with Landlord or Landlord’s agent (directly or through a broker)
with respect to space in the Building during the six (6) months immediately preceding Tenant’s request for Landlord’s consent; 

  

	 	5.	Tenant shall reimburse Landlord on demand for any reasonable costs that may be incurred in connection with any assignment or sublease, including, without limitation, the reasonable
costs of making investigations as to the acceptability of the proposed assignee or subtenant, and reasonable legal costs incurred in connection with the granting of any requested consent; 

  

	 	6.	In case of a subletting, it shall be expressly subject to all of the obligations of Tenant under this Lease and the further condition and restriction that the subleased Demised
Premises shall not be further sublet by the sublessee in whole or in part, or any part thereof suffered or permitted by the sublessee to be used or occupied by others, without the prior written consent of Landlord in each instance;

  

	 	7.	Tenant, at Tenant’s expense, shall provide and permit reasonably appropriate means of ingress to and egress from the space sublet by Tenant; and 

  

	 	8.	Tenant is not then in default under the terms, covenants and conditions of this lease on Tenant’s part to be observed and performed. 

 E. No permitted or consented to assignment or subletting shall be effective or valid for any purpose whatsoever unless and until a counterpart of the
assignment or a counterpart or reproduced copy of the sublease shall have been first delivered to the Landlord, and, in the event of an assignment, the Tenant shall deliver to Landlord a written agreement executed and acknowledged by the Tenant and
such assignee in recordable form wherein such assignee shall assume jointly and severally with Tenant the due performance of this Lease on Tenant’s part to be performed for the balance of the term of this Lease notwithstanding any other or
further assignment. 
 F. Except as provided in Paragraphs I and L hereof, any transfer by operation of law or otherwise, of Tenant’s
interest in this Lease or of a fifty (50%) percent or greater interest in 

 
Tenant (whether stock, partnership interest or otherwise) shall be deemed an assignment of this Lease for purposes of this Article except that the transfer
of the outstanding capital stock of any corporate tenant shall be deemed not to include the sale of such stock by persons or parties through the “over-the-counter-market” or through any recognized stock exchange, other than those deemed
“insiders” within the meaning of the Securities Exchange Act of 1934, as amended. 
 G. Neither any assignment of Tenant’s
interest in this Lease nor any subletting, occupancy or use of the Demised Premises or any part thereof by any person other than Tenant, nor any collection of rent by Landlord from any person other than Tenant as provided in Article 11 hereof, nor
any application of any such rent as provided in said Article 11 shall, in any circumstances, relieve Tenant of its obligations fully to observe and perform the terms, covenants and conditions of this Lease on Tenant’s part to be observed and
performed. 
 H. Notwithstanding anything to the contrary contained herein, but except with respect to an assignment pursuant to paragraphs I
and L of this Article 42, if Landlord shall consent to any assignment or subletting, then (i) in the case of an assignment, if Tenant shall receive any consideration from its assignee in connection with the assignment of this Lease, Tenant
shall pay over to Landlord, as additional rent, a sum equal to seventy five (75%) percent of any such consideration (including sums designated by the assignee as paid for the purpose of Tenant’s property in the Demised Premises), as shall
exceed the brokerage commissions, alterations expenses and attorneys’ fees and disbursements reasonably incurred by Tenant for such assignment or (ii) if Tenant shall sublet the Demised Premises or any portion thereof to anyone for rents,
additional charges or other consideration which for any period shall exceed the rents payable for the subleased space under this Lease for the same period, Tenant shall pay Landlord, as additional rent, a sum equal to seventy five (75%) percent
of any such excess less brokerage commissions, and attorneys’ fees and disbursements reasonably incurred by Tenant for such subletting. All sums payable to Landlord pursuant to subdivision (i) of this Paragraph H shall be paid on the
effective date of such assignment and all sums payable to Landlord pursuant to subdivision (ii) of this Paragraph H shall be paid on the date or dates such sums are actually paid to Tenant by the subtenant. 
 I. Tenant may, without Landlord’s prior written consent, but upon prior written notice to Landlord, assign or transfer its entire interest in this
Lease and the leasehold estate hereby created or sublet the whole of the Demised Premises to a related corporation of Tenant (as hereinafter defined); provided, however, that (i) Tenant shall not be in default in any of the terms of this Lease,
(ii) the proposed occupancy shall not increase the office cleaning requirements (if any) or impose an extra burden upon the building equipment or building services and (iii) the proposed subtenant or assignee shall not be entitled,
directly or indirectly, to diplomatic or sovereign immunity and shall be subject to the service of process in, and the jurisdiction of the courts of, New York State. A “related corporation”, as used in this Section shall mean a corporation
controlled by Tenant. For the purposes hereof, “control” shall be deemed to mean ownership of not less than fifty (50%) percent of all of the voting stock of such corporation or not less than fifty (50%) percent of all of the
legal and equitable interest in any other business entities. Any such subletting shall not be deemed to vest in any such related corporation any right or interest in this Lease or the Demised Premises nor shall it relieve, release, impair or
discharge any of Tenant’s obligations hereunder. 
 J. Each sublease shall provide that it is subject and subordinate to this Lease and
to the matters to which this Lease is or shall be subordinate, and that in the event of default by Tenant under this Lease, Landlord may, at its option, take over all of the right, title and interest of Tenant, as sublessor, under such sublease, and
such sublessee shall, at Landlord’s option, attorn to Landlord pursuant to the then executory provisions of such sublease, except that Landlord shall not (i) be liable for any previous act or omission of Tenant under such sublease or,
(ii) be subject to any offset not expressly provided in such sublease which theretofore accrued to such sublease to which Landlord has not specifically consented in writing or by any previous prepayment of more than one month’s rent.

 K. Intentionally Omitted. 
 L. Tenant may, without Landlord’s consent, but upon prior written notice to Landlord, assign its entire interest in this Lease or sublet all or a portion of the Demised Premises to a successor corporation of Tenant (as hereinafter
defined); provided, however, that (i) Tenant shall not be in default in any of the terms of this Lease beyond applicable grace, notice and/or cure periods (ii) the proposed occupancy shall not increase the office cleaning requirements (if
any) or impose an extra burden upon the building equipment or building services and (iii) the proposed subtenant or assignee shall not be entitled, directly or indirectly, to diplomatic or sovereign immunity and shall be subject to the service
of process in, and the jurisdiction of the courts of, New York State. A “successor corporation”, as used in this Section shall mean (a) a corporation into which or with which Tenant, its corporate successors or assigns, is merged or
consolidated, in accordance with applicable statutory provisions for the merger or consolidation of 

 
corporations, provided that by operation of law or by effective provisions contained in the instruments of merger or consolidation, the liabilities of the
corporations participating in such merger or consolidation are assumed by the corporation surviving such merger or consolidation, or (b) a corporation acquiring this lease and the term hereof and the estate hereby granted, the goodwill and all
or substantially all of the other property and assets (other than capital stock of such acquiring corporation) of Tenant, its corporate successors or assigns, and assuming all or substantially all of the liabilities of Tenant, its corporate
successors and assigns, or (c) any corporate successor to a successor corporation becoming such by either of the methods described in subdivisions (a) and (b) above; provided that, immediately after giving effect to any such merger or
consolidation, or such acquisition and assumption, as the case may be, the corporation surviving such merger or created by such consolidation or acquiring such assets and assuming such liabilities, as the case may be, shall have assets,
capitalization and a net worth, as determined in accordance with generally accepted accounting principles, at least equal to the assets, capitalization and net worth, similarly determined, of Tenant, its corporate successors or assigns, immediately
prior to such merger or consolidation or such acquisition and assumption, as the case may be. 
 M. Notwithstanding anything contained in
this Lease to the contrary, the offering of collocation services, including to other Building tenants, shall not constitute a sublease or underletting requiring Landlord’s consent provided Tenant notifies Landlord in writing, in accordance with
Article 28 hereof, in advance of such collocation. Furthermore, any collocation shall be subject to the terms and conditions of this Lease, including without limitation, Articles 3 and 49 L hereof.

connection with Landlord’s agents’ review, modification, approval, supervision and/or coordination of plans and specifications for any Tenant work, Tenant shall, promptly upon demand, reimburse Landlord’s agent for any reasonable
out-of-pocket fees, expenses and other charges incurred by Landlord in connection with the review, modification and/or approval of such plans and specifications, (including, but not limited to, fees charged by Landlord’s architect or other
agents for attending meetings with Tenant and/or its agents in connection with said review or alterations).

 46. ELECTRIC CURRENT: 
 A. Definitions 
 For purposes of this
Article 46, the following term shall have the following meanings: 
 The term “Electricity Cost”, shall mean, the then on-peak and
off-peak costs per kilowatt hour for energy and peak demand cost per kilowatt as expressed in the Electricity Provider’s (hereinafter defined) rate classification (for a tenant of the Building purchasing electric service directly from the
Electricity Provider) as adjusted from time to time for fuel adjustment charges, rate adjustment charges, sales tax and/or any other factors. 
 The term “Electricity Provider” shall mean any utility and any other energy services company or companies, whether or not affiliated with Landlord, that is supplying electric energy and capacity including but not limited to
generation, transmission, distribution and other ancillary services, to the building and the Demised Premises, or directly to Tenant, regardless of 

 
whether such Electricity Provider generates its own electricity at or near the building or delivers such electricity over transmission and distribution
equipment owned by the Electricity Provider, the local utility or any other Electricity Provider. Landlord may purchase such services from more than one Electricity Provider and Landlord may change Electricity Provider(s) at its sole discretion.

 B. Method of Furnishing Electric Current to the Demised Premises 
 Landlord agrees, subject to Paragraph 5 hereof, to furnish electricity to Tenant on a “submetering” basis. 
  

	 	1.	Submetering: A meter or meters (collectively, the “Submeter”) are installed to measure Tenant’s consumption of electric service. Tenant will pay Landlord or
Landlord’s designated agent, as additional rent for electric service, the amounts, as determined by the Submeter, for the purpose of measuring Tenant’s consumption and demand. Such service shall be computed at Electricity Cost, plus a fee
(the “Overhead Charge”) equal to three (3%) percent of such charge, representing administrative/overhead costs to Landlord. The amounts computed from the Submeter together with the Overhead Charge are herein collectively called the
“Electricity Additional Rent”. Landlord may from time to time, increase the Electricity Additional Rent based upon any increase in Electricity Cost. Where more than one meter measures the electric service to Tenant (including such electric
energy as is consumed in connection with the operation of the HVAC units and/or other appurtenant equipment servicing the Demised Premises), the electric service rendered through each meter may be computed and billed separately as above set forth.
Bills for the Electricity Additional Rent (the “Bills”) shall be rendered to Tenant at such time as Landlord may elect. In the event that such Bills are not paid within thirty (30) days after the same are rendered, Landlord may, upon
five (5) business days written notice (unless the Bills are paid within such (5) business days), discontinue the service of electric current to the Demised Premises without releasing Tenant from any liability under this Lease and without
Landlord or Electrical Providers incurring any liability for any damage or loss sustained by Tenant as the result of such discontinuance. If any tax is imposed upon Landlord’s receipts from the sale or resale of electric current to Tenant by
any Federal, state or municipal authority, Tenant agrees that, unless prohibited by law, Tenant’s Percentage of such taxes shall be passed on to, and included in the bill of, and paid by Tenant to Landlord as additional rent.

  

	 	2.	Tenant agrees not to connect any additional electrical equipment of any type to the building electric distribution system, without Landlord’s prior written consent, which
consent shall not be unreasonably withheld. Any additional risers, feeders, or other equipment proper or necessary to supply Tenant’s electrical requirements, upon written request of Tenant, will be installed by Landlord, at the sole cost and
expense of Tenant, if, in Landlord’s sole judgment, the same are necessary and will not cause permanent damage or injury to the building or the Demised Premises, or cause or create a dangerous or hazardous condition or entail excessive or
unreasonable alterations, repair or expense or interfere with or disturb other tenants or occupants taking into account other present and reasonably future requirements for additional power. 

  

	 	3.	Tenant’s use of electric current in the Demised Premises shall not at any time exceed the capacity of any of the electrical conductors and equipment in or otherwise servicing
the Demised Premises. 1000 amps, 480 volt service is or will be made available to the Demised Premises. Any upgrades to such electric capacity requested by Tenant may be made available to Tenant upon written request therefor (which request shall be
accompanied by a load letter evidencing Tenant’s electric requirements) subject to availability and payment of Landlord’s then prevailing fee therefor (presently $500 per amp of electric power). 

 Tenant shall not make or perform or permit the making or performing of, any alterations to wiring, installations or other electrical facilities in or
serving the Demised Premises without the prior written consent of Landlord in each instance (which shall not be unreasonably withheld). Should Landlord grant any such consent, all additional risers or other equipment required therefor shall be
installed by Landlord and the cost thereof shall be paid by Tenant upon Landlord’s demand. 
  

	 	4.	 Neither Landlord nor its Electrical Providers shall be liable in any way to Tenant for any failure or defect in the supply or character of electric energy furnished
to 

	 	 
the Demised Premises by reason of any requirement, act or omission of the utility serving the building with electricity or for any other reason.

  

	 	5.	If at any time during the term of this Lease, the Electricity Provider or any other public utility company servicing the Building requires Landlord to recapture any excess electric
capacity then servicing the Demised Premises, to the extent not being used by Tenant, then Landlord shall recapture any such excess electricity as mandated by the Electricity Provider, or any other utility company, without compensation to Tenant or
any abatement of fixed rent or additional rent. Additionally, to the extent an excess electric capacity charge is imposed on Landlord by the Electricity Provider, or by any other utility company servicing the Building, as a result of the utilization
of less than the full electric capacity then available to the Demised Premises, Tenant shall pay its proportionate share of said charges to the extent that Tenant is not fully utilizing its electric capacity serving the Demised Premises.

  

	 	6.	If at any time during the term of this Lease, the Electricity Provider or any other public utility company servicing the Building requires Landlord to recapture any excess electric
capacity then servicing the Demised Premises, to the extent not being used by Tenant, then Landlord shall recapture any such excess electricity as mandated by the Electricity Provider, or any other utility company, without compensation to Tenant or
any abatement of fixed rent or additional rent. Additionally, to the extent an excess electric capacity charge is imposed on Landlord by the Electricity Provider, or by any other utility company servicing the Building, as a result of the utilization
of less than the full electric capacity then available to the Demised Premises, Tenant shall pay its proportionate share of said charges to the extent that Tenant is not fully utilizing its Basic Capacity and/or Upgrade, as the case may be.

  

	 	7.	Notwithstanding any provisions of this Article 46, in no event shall (a) the fixed rent under this Lease be reduced by virtue of this Article 46 and (b) the cost to Tenant
for electric energy be less than 103% of Electricity Cost. 

  

	 	8.	Notwithstanding anything herein to the contrary, in no event shall the Electricity Cost be less than Landlord’s cost for purchasing electricity from the Electricity Provider.

 47. BROKER: 
 Landlord and Tenant represent and warrant to the other that neither consulted nor negotiated with any broker or finder with regard to the rental of the Demised Premises from Landlord other than JEMB Realty Corp. and
Cushman & Wakefield (together, the “Broker”). Landlord and Tenant agree to indemnify and hold the other harmless from any claims, suits, damages, costs and expenses suffered by the other by reason of any breach of the foregoing
representation. Landlord shall pay any commission due Broker in accordance with Landlord’s separate agreement with Broker. 
 48.
BINDING EFFECT: 
 It is specifically understood and agreed that this Lease may be offered to Tenant for signature by the
leasing or managing agent and is subject to Landlord’s acceptance and approval, and that Tenant shall have affixed its signature hereto with the understanding that such act shall not, in any way, bind Landlord or its agent until such time as
this Lease shall have been approved and executed by Landlord and delivered to Tenant. 
 49. MISCELLANEOUS: 

A. Without incurring any liability to Tenant, Landlord may permit access to the Demised Premises and open the same, whether or not Tenant shall be
present, upon demand of any receiver, trustee, assignee for the benefit of creditors, sheriff, marshall 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 Demised Premises), or upon demand of any representative of the fire, police, Building, sanitation or other department of the city, state or federal governments. 
 B. No receipt of monies by Landlord from Tenant, after any reentry or after the cancellation or termination of this Lease in any lawful manner, shall
reinstate the lease; and after the service of notice to terminate this Lease, or after the commencement of any action, proceeding or other remedy, Landlord may demand, receive and collect any monies due, and 

 
apply them on account of Tenant’s obligations under this Lease but without in any respect affecting such notice, action, proceeding or remedy, except
that if a money judgment is being sought in any such action or proceeding, the amount of such judgment shall be reduced by such payment. 
 C. If Tenant is in arrears in the payment of fixed rent or additional rent, Tenant waives its right, if any, to designate the items in arrears against which any payments made by Tenant are to be credited and Landlord may apply any of such
payments to any such items in arrears as Landlord, in its sole discretion, shall determine, irrespective of any designation or request by Tenant as to the items against which any such payments shall be credited. 
 D. No payment by Tenant nor receipt by Landlord of a lesser amount than may be required to be paid hereunder shall be deemed to be other than on account
of any such payment, nor shall any endorsement or statement on any check or any letter accompanying any check tendered as payment 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 payment due or pursue any other remedy in this Lease provided. 
 E. If in this Lease it is provided
that Landlord’s consent or approval as to any matter will not be unreasonably withheld, and it is established by a court or body having final jurisdiction thereover that Landlord has been unreasonable the only effect of such finding shall be
that Landlord shall be deemed to have given its consent or approval; but Landlord shall not be liable to Tenant in any respect for money damages by reason of withholding its consent except to the extent a court of competent jurisdiction finds, by
way of a final un-appealable judgment, that Landlord had acted in bad faith when withholding its consent. 
 F. If payment of any Fixed Rent
or Additional Rent shall not have been paid by the fifth business day after the date on which such amount was due and payable, then, in addition to and without waiving or releasing any other remedies of Landlord, a late charge of four cents ($.04)
for each dollar overdue shall be payable on demand by Tenant to Landlord as damages for Tenant’s failure to make prompt payment. In default of payment of any late charges, Landlord shall have (in addition to all other remedies) the same rights
as provided in this Lease for nonpayment of Fixed Rent. Nothing in this Section contained and no acceptance of late charges by Landlord shall be deemed to extend or change the time for payment of Fixed Rent or Additional Rent. 
 G. If the Expiration Date or the date of sooner termination of this Lease shall fall on a day which is not a business day, then Tenant’s obligations
pursuant to Article 22 hereof shall be performed on or prior to the next succeeding business day. Tenant expressly waives, for itself and for any person claiming through or under Tenant, any rights which Tenant or any such person may have under the
provisions of Section 2201 of the New York Civil Practice Law and Rules and of any similar or successor law of same import then in force, in connection with any holdover proceedings which Landlord may institute to enforce the provisions of this
Lease. If the Demised Premises are not surrendered upon the termination of this Lease, Tenant hereby indemnifies Landlord against liability resulting from delay by Tenant in so surrendering the Demised Premises, including any claims made by any
succeeding tenant or prospective tenant founded upon such delay. In the event Tenant remains in possession of the Demised Premises after the termination of this Lease without the execution of a new lease, Tenant, at the option of Landlord, shall be
deemed to be occupying the Demised Premises as a tenant from month to month, at a monthly rental equal to two (2) times the fixed rent and additional rent payable during the last month of the term, subject to all of the other terms of this
Lease insofar as the same are applicable to a month-to-month tenancy. Tenant’s obligations under this Paragraph shall survive the expiration or sooner termination of this Lease. 
 H. This Lease shall be governed in all respects by the laws of the State of New York. Tenant hereby specifically consents to jurisdiction in the State of
New York in any action or proceeding arising out of this Lease and/or the use and occupation of the Demised Premises. 
 I. Tenant shall not
cause or permit any Hazardous Materials (hereinafter defined) to be used, stored, transported, released, handled, produced or installed in, on or from the Demised Premises or the Building in violation of applicable law. “Hazardous
Materials”, as used herein, shall mean any flammables, explosives, radioactive materials, hazardous wastes, hazardous and toxic substances or related materials, asbestos or any material containing asbestos, or any other substance or material
included in the definition of “hazardous substances”, hazardous wastes”, “hazard materials”, “toxic substances”, “contaminants” or any other pollutant, or otherwise regulated by any Federal, state or
local environmental laws, ordinance, rule or regulation including, without limitation, the Comprehensive Environmental Response Compensation and Liability Act of 1980, as amended, the Hazardous Materials Transportation Act, as amended, the Resource
Conservation and Recovery Act, as amended, and in the regulations adopted and publications promulgated pursuant to each of the foregoing. In the event of a violation of any of the foregoing provisions of this Paragraph, Landlord may, without notice

 
and without regard to any grace period contained herein, take all remedial action deemed necessary by Landlord to correct such condition and Tenant shall
reimburse Landlord for the cost thereof, upon demand, as additional rent. At lease one (1) year prior to the Expiration Date, Tenant shall identify and forward written notice of any Hazardous Materials brought into the Demised Premises by
Tenant or any other party claiming through or under Tenant. 
 J. The individual signatories to this lease each represent that they are duly
authorized to execute this document. Upon Landlord’s request, Tenant will execute and deliver to Landlord a Secretary’s Certificate setting forth the authority of the officer executing the lease by and on Tenant’s behalf. 

K. Any representations made by any other party other than Landlord itself shall not be binding upon Landlord. 
 L. To the extent that Tenant requires use of any riser space i.e., vertical or horizontal running of piping, conduit, wire or fiber optics (whether or
not encased in conduit) the following charges (subject to adjustment) shall apply. 
 1. $6.00 per linear foot per annum for each conduit.

 The aforesaid charges shall increase a compounded 3% per annum; provided however, Tenant shall not be responsible for such charges in
connection with using conduit existing as of the Commencement Date. 
 M. If, at any time during the term of this lease, Landlord expends any
sums for alterations or improvements to the building which are required to be made pursuant to any law, ordinance or governmental regulation, or are necessary to insure the safety of all Building systems, including, without limitation installation
of an exhaust or other ventilation system to service all the generators in the Building, Tenant shall pay to Landlord, as additional rent, Tenant’s Proportionate Share of such costs within thirty (30) days after demand therefor. If,
however, the cost of such alteration or improvement is one which is required to be amortized over a period of time pursuant to applicable governmental regulations, Tenant shall pay to Landlord, as additional rent, during each year in which occurs
any part of this lease term, Tenant’s Proportionate Share of the reasonable annual amortization of the cost of the alteration or improvement. 
 N. Tenant shall during the term hereof have the sole use of the Improvements listed on Exhibit D (which are Tenant’s responsibility to maintain during the term hereof, at its sole cost and expense). 
 O. Landlord agrees to reimburse Tenant for actual out-of-pocket expenses, in an amount not to exceed $25,000, incurred by Tenant for retaining
third-parties to assess the feasibility of the Demised Premises and Improvement’s for Tenant’s business. Landlord will reimburse Tenant for such expenses within thirty (30) days of presentment of invoices therefor, that have been
marked “paid” by the payee. 
 P. Subject to the terms and conditions of this Lease, including without limitation Article 3 and 49
L hereof, and upon prior approval by Landlord, Tenant shall have the right to install riser’s to the Demised Premises, and/or use all existing connected risers and already connected components, as may be required. 
 Q. Subject to the terms and conditions of this Lease including without limitation Articles 3 and 49 L hereof, and upon prior approval by Landlord, Tenant

 R. Provided Tenant is not in default
hereunder, Landlord will execute a lien waiver, substantially in the form attached hereto as Exhibit E. 
 50. DOWNTOWN TAX

 Landlord and Tenant hereby acknowledge and agree that to the extent available, Tenant, at Tenant’s sole cost and
expense, may make application (the “Application”) after the Commencement Date of this Lease to the appropriate governmental authority in order to receive certain tax abatements (the “Tax Abatement”) for the Building pursuant to
“The Lower Manhattan commercial Revitalization Program”) (the “Program”) created by Title 4A of Article 4 of the real Property Tax Law, §§499-a et. seq. (the “Law”); provided, however, Tenant shall not make
the Application (nor continue with its being processed) unless all of the following are and remain true and correct, (and all of which are in any event hereby agreed to and acknowledged by Tenant), (whereby, if all of the following are and remain
true and correct, Landlord shall cooperate with Tenant in Tenant’s attempt to obtain the Tax Abatement for the Building by joining in the Application): (i) Tenant shall file the Application, and all related documentation in accordance with

 
all time frames and schedules as may be required by the law (and all related rules and regulations) and the Program; (ii) Tenant meets all eligibility
requirements for the Program with respect to the Premises (and, in this regard, upon request, Tenant shall deliver to Landlord upon demand all information and documentation requested by Landlord with respect to the Program, and Tenant’s
eligibility thereunder, with respect to the Premises); (iii) Landlord shall incur no cost or expense in connection with the Application or the Tax Abatement (as well as in connection with its being obtained); (iv) Tenant shall reimburse
Landlord for all of Landlord’s reasonable costs and expenses incurred in connection with the Application (and related documentation) and the Tax Abatement and its being obtained) (including, without limitation, all of Landlord’s
attorneys’ and consultants’ costs, expenses and fees in connection with the review of any documentation concerning the Application (and related documentation) and the Tax Abatement, the amount of all administrative charges or fees which
may be imposed by the Department of Finance of the City of New York in connection with the Application (and all related documentation), and in connection with ongoing compliance related to the Program, as well as all such costs, expenses and fees
which may be incurred in attending any and all hearings and/or meetings), which reimbursement shall be payable to Landlord by Tenant on demand, (v) Landlord has not made, nor will Landlord be making, any representations or warranties whatsoever
regarding the feasibility of obtaining the Tax Abatement (or any facts or circumstances related thereto), or whether any Tax Abatement which may be received will subsequently be reduced or eliminated, or regarding Tenant’s eligibility for
receiving the Tax Abatement, or whether this Lease properly conforms with requirements imposed by the Program, or whether the appropriate expenditures as may be imposed by the Program will be made at the Premises and the Building (and Landlord is
not required to perform any other work other than as may expressly be set forth in this Lease; (vi) all information which may be or is set forth on the Application as well as on all related documentation shall be true and correct in all
respects and, in this regard, Tenant shall indemnify and hold Landlord harmless from any and all claims, losses, expenses or liabilities in connection with any inaccuracy; (vii) Landlord shall incur no liability whatsoever in connection with
the Application, or any other related documentation, the Program, or the Tax Abatement (or in connection with its being obtained) and, in this regard, Tenant shall indemnify and hold Landlord harmless from any and all claims, losses, expenses or
liabilities in connection therewith; and (viii) Tenant complies, and continues to comply, at all times with all of the provisions and requirements of the Program, including without limitation, all eligibility requirements, together with the
rules promulgated thereunder and, in this regard, Tenant shall indemnify and hold Landlord harmless from any claims, losses, expenses or liabilities in connection with Tenant’s failure to so comply. 
 Notwithstanding the above, Landlord, upon written request made by Tenant, agrees to join with Tenant in signing the Application (to the extent Landlord
is required by the Program to do so), provided, however, Landlord shall not be required to join in if any of the terms or conditions set forth above are untrue in any respect, or if Tenant is in default under this Lease (and, in this regard, to the
extent Landlord does so join in it shall not be deemed to be an acknowledgment by Landlord that any of the applicable provisions or requirements set forth above are necessarily true, nor shall the joining in ever be deemed to be a waiver of any such
provisions or requirements). 
 Provided all of the terms and conditions set forth above in this Article are fully complied with by Tenant
and Tenant is not otherwise in default under this Lease (including, without limitation, as provided in this Paragraph above), then, in such event, Landlord shall provide Tenant with a credit (the “Tax Credit”) against the Tax Amount
payable by Tenant under this Lease in an amount for any applicable Tax Year occurring during the Term which equals (but does not exceed) the full amount of such particular Tax Year of the Tax Abatement which is exclusively attributable to the
Premises pursuant to the Program and which is actually received by Landlord (with such amount being called the “Actual Benefits”). 
 Tenant shall pay to Landlord upon demand, as Additional Rent, the amount of the Actual Benefits that have been credited against the Tax Amount becoming due hereunder if such Tax Abatement related to the Actual Benefit is thereafter revoked
for any reason whatsoever (such as, for example, and without otherwise limiting, as a result of the exercise by Tenant of a right to terminate this Lease, or assignment of this Lease, or subleasing of the Premises, or for Tenant’s failure to
meet and continue to meet any of the eligibility requirements under the Program, or Tenant’s breach under this Lease), together with any interest at the highest rate allowed by law commencing upon the date such payment is to be made, along with
all penalties which may be imposed against Landlord in connection with such Actual Benefits. 
 In addition, as set forth in the Law, all
abatements granted under the Program with respect to the Building pursuant to the Program will automatically be revoked (without notice) if, during the benefit period, real estate taxes or water or sewer charges or other lienable charges are unpaid
for more than one year, unless such delinquent amounts are paid as provided in the Law. 
 The provisions of this Article shall survive the
expiration or earlier termination of this Lease.

 55. EXTENSION OF TERM: 
 A. Subject to the provisions of Paragraph E hereof, Tenant shall have
the right to extend the term of this Lease for one (1) additional term of five (5) years commencing on the day following the expiration of the initial term of this Lease (hereinafter called the “Commencement Date of the Extension
Term”) (such additional term is hereinafter called the “Extension Term”) provided that: 
 1. Tenant shall give Landlord notice
(hereinafter called the “Extension Notice”) of its election to extend the term of this Lease at least nine (9) months, prior to the expiration of the initial term of this Lease, and 
 2. Tenant is not in default (after the expiration of applicable grace periods, if any) under this Lease as of the time of the giving of the Extension
Notice and the Commencement Date of the Extension Term. 
 3. Tenant shall be in actual physical occupancy of not less than 75% of the
rentable area of the Demised Premises. 
 B. The Fixed Rent payable by Tenant to Landlord during the Extension Term shall be a sum equal to
the fair market rent for the Demised Premises as determined as of the date occurring six (6) months prior to the Commencement Date of the Extension Term (such date is hereinafter called the “Determination Date”) and which
determination shall be made within a reasonable period of time after the occurrence of the Determination Date pursuant to the provisions of Paragraph C hereof. In determining the fair market rent, the provisions of Article 39 of this Lease shall
remain in effect during the Extension Term with the same base year as set forth therein. 
 C. 1. Landlord and Tenant shall endeavor to agree
as to the amount of the fair market rent for the Demised Premises pursuant to the provisions of Paragraph B hereof, during 

 
the thirty (30) day period following the Determination Date. In the event that Landlord and Tenant can not agree as to the amount of the fair market
rent within such thirty (30) day period following the Determination Date, then Landlord or Tenant may initiate the appraisal process provided for herein by giving notice to that effect to the other, and the party so initiating the appraisal
process (such party hereinafter called the “Initiating Party”) shall specify in such notice the name and address of the person designated to act as an arbitrator on its behalf. Within thirty (30) days after the designation of such
arbitrator, the other party (hereinafter called the “Other Party”) shall give notice to the Initiating Party specifying the name and address of the person designated to act as an arbitrator on its behalf. If the Other Party fails to notify
the Initiating Party of the appointment of its arbitrator within the time above specified, then the appointment of the second arbitrator shall be made in the same manner as hereinafter provided for the appointment of a third arbitrator in a case
where the two arbitrators appointed hereunder and the parties are unable to agree upon such appointment. The two arbitrators so chosen shall meet within ten (10) days after the second arbitrator is appointed and if, within fifteen
(15) days after the second arbitrator is appointed, the two arbitrators shall not agree, they shall together appoint a third arbitrator. In the event of their being unable to agree upon such appointment within fifteen (15) days after the
appointment of the second arbitrator, the third arbitrator shall be selected by the parties themselves if they can agree thereon within a further period of fifteen (15) days. If the parties do not so agree, then either party, on behalf of both
and on notice to the other, may request such appointment by the American Arbitration Association (or organization successor thereto) in New York City in accordance with its rules then prevailing. 
 2. Each party shall pay the fees and expenses of the one of the two original arbitrators appointed by or for such party, and the fees and expenses of the
third arbitrator and all other expenses (not including the attorneys fees, witness fees and similar expenses of the parties which shall be borne separately by each of the parties) of the arbitration shall be borne by the parties equally. 

3. The majority of the arbitrators shall determine the fair market rent of the Demised Premises and render a written certified report of their
determination to both Landlord and Tenant within thirty (30) days of the appointment of the first two arbitrators or thirty (30) days from the appointment of the third arbitrator if such third arbitrator is appointed pursuant to this
Paragraph; and the fair market rent, so determined, shall be applied to determine the Fixed Rent pursuant to Paragraph B hereof. 
 4. Each
of the arbitrators selected as herein provided shall have at least ten (10) years experience in the leasing and renting of telecom space in comparable buildings in the Borough of Manhattan. 
 5. If Landlord notifies Tenant that the Fixed Rent for the Extension Term shall be equal to the Fixed Rent and additional rent in effect under this Lease
for the last month of the initial term (without giving effect to any temporary abatement thereof), then the provisions of Subsection 1 of this Paragraph C shall be inapplicable and have no force or effect. 
 6. In the event Landlord or Tenant initiates the appraisal process and as of the Commencement Date of the Extension Term the amount of the fair market
rent has not been determined, Tenant shall continue to pay the fixed rent and additional rent in effect under this Lease for the last month of the initial term and when such determination has been made, an appropriate retroactive adjustment shall be
made as of the Commencement Date of the Extension Term. 
 D. Except as provided in Paragraphs A and B hereof, Tenant’s occupancy of the
Demised Premises during the Extension Term shall be on the same terms and conditions as are in effect immediately prior to the expiration of the initial term of this Lease, provided, however, Tenant shall have no further right to extend the term of
this Lease pursuant to this Article 55. 
 E. If Tenant does not send the Extension Notice pursuant to the provisions of Paragraph A hereof,
this Article 55 shall have no force or effect and shall be deemed deleted from this Lease. 
 F. If this Lease is renewed for the Extension
Term, then Landlord or Tenant can request the other party hereto to execute an instrument in form for recording setting forth the exercise of Tenant’s right to extend the term of this Lease and the last day of the Extension Term. 
 G. If Tenant exercises its right to extend the term of this Lease for the Extension Term pursuant to this Article 55, the phrases “the term of this
Lease” or “the term hereof” as used this Lease, shall be construed to include, when practicable, the Extension Term. 

 56. GENERATOR USE: 
 Subject to all applicable provisions of the Lease, Tenant hereby leases from Landlord certain space
on the 17th floor as delineated on the Generator Plan attached hereto as Exhibit A, containing the generator (the
“Generator”) delineated on Exhibit D attached hereto, for the sole purpose of the operation and maintenance of the Generator. Tenant shall not be responsible for charges other than for fuel, overhead, electricity and maintenance, as
provided herein, in connection with using the Generator and Battery Plant (as shown in Exhibit D). Tenant shall have sole use of the Generator during the term hereof. 
 Tenant shall reimburse Landlord, upon demand, for Landlord’s actual cost for diesel fuel
consumed by the Generator as indicated on an existing meter, to be maintained by Tenant at its expense. Tenant shall also pay Landlord’s charge, upon demand, for overhead and supervision in connection with the foregoing, in an amount equal to
5% of Tenant’s payment for diesel fuel consumption by the Generator. Tenant shall reimburse Landlord promptly upon demand for all additional fuel lines, pumps, piping meters and other equipment or insulations not in place as of the Commencement
Date that are reasonably necessary for the operation of Tenant’s Generator. At Tenant’s option, subject to Landlord’s prior approval, Tenant shall have the right to replace (at its sole cost and expense) rather than repair the
Generator, provided the Generator is replaced with another generator of equal or better quality and of equal or greater power, in which event the replacement generator will be maintained by Tenant pursuant hereto and be surrendered by Tenant,
together with the Demised Premsies, at the end of the term pursuant to Articles 3 and 24 hereof. Subject to the rights of other tenants or occupants in the Building, Landlord shall make available to Tenant reasonable access to the 17th floor seven (7) days a week, 24 hours per day, subject to Landlord’s security measures for the maintenance, repair,
operation and use of the Generator. References herein to the Generator shall be deemed to include risers and the electrical conduits connecting the Generator to the Demised Premises and fuel lines appurtenant thereto. 
 All maintenance and repairs to the Generator (including any replacement generator) shall be performed by Tenant at Tenant’s sole cost and expense.

 57. ACCESS TO DEMISED PREMISES: 
 Access to the Demised Premises, with corresponding ingress and egress through the Building and any associated common areas, shall be available to Tenant seven (7) days a week, 24 hours per day it being understood
and agreed that services will only be provided by Landlord as set forth in Article 29 and that any such access on non-business days or hours shall be subject to Landlord’s reasonable security requirements. 
 58. AS IS: 
 Tenant
acknowledges and agrees to accept the Demised Premises in its “as is” condition as of the Commencement Date and acknowledges that Landlord shall have no obligation to perform any work in or to the Demised Premises except for those items
