to Subtenant of such default (provided, however, that Sublandlord shall not be required to deliver such notice more than two (2) times
in any twelve (12) month period, it being understood that any further failure to pay any Fixed Rent or Additional Rent on the due date
thereof within such twelve (12) month period shall constitute an immediate Event of Default), or (B) Subtenant shall fail to comply with
any term, provision or covenant of this Sublease or any applicable term, provision or covenant of the Lease, or Subtenant shall violate
any rules and regulations now or hereafter established for the operation of the Building and Subtenant shall fail to remedy such failure
within fifteen (15) days after written notice from Sublandlord, or if such failure complained of shall be of a nature that the same cannot
be completely cured and remedied within said fifteen (15) day period, and Subtenant shall not (1) promptly upon the giving by Sublandlord
of such notice, advise Sublandlord of Subtenant’s intention to institute all steps necessary to remedy such situation, (2) promptly institute
and thereafter diligently pursue all steps necessary to remedy the same and (3) effect such remedy within a reasonable time (not to exceed
sixty (60) days) after the date of the giving of said notice by Sublandlord and in any event prior to such time as would either (y) subject
Landlord, Sublandlord, Sublandlord’s agents or any mortgagee or ground lessee to civil or criminal liability or prosecution for a crime,
or (z) cause a default under any applicable mortgage or ground lease; or


 


 (ii) if (A) any petition is filed by Subtenant

    5


     


    

 


(b) Upon
the occurrence of an Event of Default, Sublandlord shall have the right, at its option, to do and perform any one or more of the following,
in addition to, and not in limitation of any other remedy or right permitted it by law, by this Sublease or by the Lease:


 


(i) terminate
this Sublease, in which event Subtenant shall immediately surrender the Subleased Premises to Sublandlord, but if Subtenant shall fail
to do so, Sublandlord may, without prejudice to any other right or remedy Sublandlord may have, either by law or under this Sublease or
otherwise, obtain possession or rent in arrears or damages for breach of contract, enter upon the Subleased Premises and expel or remove
Subtenant and Subtenant’s personal property, with or without force and without being liable to Subtenant, and Subtenant agrees to indemnify
and hold Sublandlord harmless for all losses or damage which Sublandlord may suffer by reason of such termination, whether through inability
to relet the Subleased Premises or through decrease in rent or by damage to the Subleased Premises, or otherwise, or


 


(ii) enter
the Subleased Premises and remove Subtenant and its personal property therefrom without terminating this Sublease or being liable to Subtenant
in any manner whatsoever for such acts, and, at Sublandlord’s option, relet the Subleased Premises as the agent of Subtenant and receive
rent therefor, and in such event Subtenant shall be liable on a monthly basis when rent is otherwise due and payable to Sublandlord for
any deficiency which may arise by reason of such reletting during the remainder of the Term of this Sublease, but shall not be entitled
to any surplus so arising. In the event of a conflict between the provisions of this Paragraph 8 and the provisions of the Lease, the
provisions of this Paragraph 8 shall prevail.


 


9. Subletting
and Assignment.


 


(a) Subtenant
shall not assign, mortgage, pledge, encumber or in any manner transfer this Sublease or any part thereof nor sublet or suffer the Subleased
Premises or any part thereof to be used by others, except as expressly permitted by this Sublease and the Lease. It is understood that
a change in control of Subtenant shall be deemed to constitute an assignment of this Sublease. The provisions of the Lease relating to
assignment and subletting shall be deemed to be incorporated into this Sublease.


 


(b) If
this Sublease is assigned in violation of the provisions of this Sublease, Sublandlord may and is hereby empowered to collect rent from
the assignee. In such event, Sublandlord may apply the net amount received by it to the Fixed Rent, Additional Rent or any other payments
herein reserved or provided for, and no such collection shall be deemed a waiver of the covenant herein against assignment, mortgage,
pledge or encumbrance, or an acceptance of the assignee as a tenant or subtenant under this Sublease or a release of Subtenant from the
further performance of its covenants herein. If the Subleased Premises or any part thereof is sublet or occupied by others in violation
of the provisions of this Sublease, Sublandlord is hereby empowered to collect rent from the subtenant or other occupant, and to apply
the same to the curing of any default hereunder in any order of priority Sublandlord may elect, any unexpended balance to be applied by
Sublandlord against any rental or other obligations subsequently becoming due. The making of any assignment, mortgage, pledge, encumbrance
or subletting in whole or in part, and whether or not in violation of the provisions of this Sublease, shall not operate to relieve Subtenant
from its obligations under this Sublease and, notwithstanding any such assignment, mortgage, pledge, encumbrance or subletting, Subtenant
shall remain liable for the payment of all Fixed Rent, Additional Rent and other charges and for the due performance of all the covenants,
agreements, terms and provisions of this Sublease until the end of the Term. Each and every assignee, whether as assignee or as successor
in interest of Subtenant or as assignee or successor in interest of any assignee, shall immediately be and become and remain liable jointly
and severally with Subtenant and with each other for the payment of the Fixed Rent, Additional Rent and other charges payable under this
Sublease and for the due performance of all the covenants, agreements terms and provisions of this Sublease on the part of Subtenant to
be paid and performed until the end of the Term.


 




    6


     


    

 


(c) Any
proposal by Subtenant to assign this Sublease or to further sublet the Subleased Premises or any portion thereof shall be subject to the
prior written consent of Landlord and Sublandlord. Sublandlord’s consent to a proposed assignment or subletting of the Subleased
Premises shall be deemed to have been granted provided that Landlord has given its consent therefor. Subtenant shall reimburse Sublandlord
for all reasonable out-of-pocket expenses incurred in connection with a proposed assignment or subletting.


 


10. Liability
Insurance.


 


(a) Neither
Sublandlord nor its successors, assigns, employees or agents shall be liable for any loss of or damage to property of Subtenant or Subtenant’s
subtenants, assigns, employees, agents or visitors, except for loss or damage resulting from Sublandlord’s gross negligence or willful
misconduct. With respect to the Subleased Premises, Sublandlord, its successors, assigns, employees and agents shall not be liable for
any injury or damage to persons or property except for loss or damage resulting from the gross negligence or willful misconduct of Sublandlord,
its successors, assigns, employees and agents.


 


(b) Subtenant
shall maintain with respect to the Subleased Premises comprehensive general public liability insurance, property insurance and other insurance
in the manner and with the minimum limits set forth in the Lease, with insurance companies qualified to do business in the State of New
York and otherwise meeting the standards set forth in the Lease, insuring Subtenant, Sublandlord, Landlord and any other parties required
in accordance with the Lease as named insureds, against, inter alia, claims and liabilities for bodily injury or death to persons, and
damage to property. Each party shall look exclusively to any insurance carried by it pursuant to this Sublease and the Lease for loss
or damage to property resulting from the negligence of the other party or its agents, servants, employees, contractors, invitees or licensees,
and, to the extent permitted by law, Sublandlord and Subtenant each hereby releases and waives all right of recovery against the other
or anyone claiming through or under each of them by way of subrogation or otherwise, provided that such waivers of liability are permitted
and are available under both Sublandlord’s and Subtenant’s policies of insurance or such waivers are approved by their insurance carriers.
Each party agrees to pay the added cost, if any, of obtaining such approval from its insurance carrier. Subtenant shall deliver certificates
of insurance to Sublandlord with respect to all insurance required under this Sublease and the Lease on or before the signing of this
Sublease by Subtenant. Each of Subtenant’s policies of insurance shall provide that such policy may not be materially changed, amended,
canceled or allowed to lapse except upon thirty (30) days’ prior notice to Sublandlord, Landlord and any other parties required in accordance
with the Lease. Such insurance shall be subject to Sublandlord’s approval as to form, content, coverage and expiration dates, which approval
shall be deemed granted if not refused within fifteen (15) days after delivery of the certificates of insurance to Sublandlord.


 


11. Indemnification.
Except as provided in Paragraph 10 hereof, Subtenant shall indemnify and hold harmless Sublandlord from and against all claims, losses,
costs, damages, expenses and liabilities (including, but not limited to, the costs of legal proceedings and reasonable attorneys’ fees
and disbursements) which Sublandlord may incur, pay or have asserted against it by reason of any injuries to persons occurring in, on
or about the Subleased Premises caused by the acts or omissions of Subtenant, its agents, employees, guests or invitees or by reason of
any breach, failure or default hereunder on Subtenant’s part, including any breach or default which results in a breach of or possible
termination or forfeiture of the Lease. In the event of a conflict between the provisions of this Paragraph 11 and any provision of the
Lease, the provisions of this Paragraph 11 shall prevail. The provisions of this Paragraph 11 shall survive the expiration or earlier
termination of this Sublease.


 




    7


     


    

 


12. Subtenant’s
Rights. Notwithstanding anything to the contrary herein set forth, Subtenant shall in no case have any rights in respect of the Subleased
Premises greater than the rights of Sublandlord under the Lease.


 


13. Possession,
Care and Condition of Subleased Premises.


 


(a) Possession
and Condition. Subtenant acknowledges that it has examined the Subleased Premises and that it is leasing the Subleased Premises in

Premises for Subtenant’s occupancy. Subject to Paragraph 7 above, Subtenant shall, at its sole cost and expense, make any alterations

the lesser of the amount indicated in Subtenant’s requisition and the amount of the Allowance.


 


(b) Included
Property. Sublandlord shall leave the furniture, fixtures and equipment which are presently situated in the Subleased Premises, and
which are identified in Exhibit “B” which is attached hereto as an integral part hereof (the “Included Property”)
in the Subleased Premises. Subtenant shall take possession of the Included Property in its “as is”, “where is”
condition. Sublandlord makes no representations or warranties with respect to the Included Property. The Included Property shall remain
the property of Sublandlord, and Subtenant shall exercise the care of a prudent custodian in its use and care of the Included Property
during the Term. Notwithstanding the foregoing, if this Sublease has not then been terminated in accordance with the terms hereof, then,
on July 1, 2027 title to the Included Property shall, without any action on the part of the Sublandlord or Subtenant, be transferred to
Subtenant and Subtenant shall thereupon be the owner of the Included Property for all purposes. Thereafter, upon the expiration of the
Term, Subtenant at its sole cost and expense, shall remove the Included Property from the Subleased Premises. If Subtenant shall fail
to remove any of the Included Property, Sublandlord may arrange for such removal and the costs of such removal plus an incremental amount
of fifteen percent (15%) shall be paid to Sublandlord by Subtenant within fifteen (15) days after demand therefor. In addition to the
Included Property, Sublandlord shall leave the existing supplemental air conditioning unit (the “A/C Unit”) which services
the IDF closet in the Subleased Premises for Subtenant’s use. Sublandlord makes no representation as to the condition of the Unit.
It shall be the responsibility of Subtenant to maintain the Unit, to carry a maintenance contract covering the Unit and to replace the
Unit, if necessary.

the Expiration Date, Subtenant shall pay to Sublandlord within five (5) days after demand in each case one hundred twenty five percent
(125%) of all amounts that Sublandlord is required to pay Landlord on account of such holdover. In addition, Subtenant shall be liable
to Sublandlord for all damages (including consequential damages), costs and expenses (including attorneys’ fees and expenses) incurred
by Sublandlord as a consequence of the holdover.

in the amount of Two Hundred Ninety Nine Thousand Four Hundred Forty Seven and 50/100 Dollars ($299,447.50) (the “Security Deposit”).
The Security Deposit shall take the form of an irrevocable standby letter of credit in form and substance satisfactory to Sublandlord
(the “Letter of Credit”) issued by a commercial bank which is a member of the New York Clearing House Association or another
commercial bank which is acceptable to Sublandlord and shall have an initial term which is not less than one (1) year from its date of
issuance. The Letter of Credit shall provide that Sublandlord may draw thereunder by the submission of only a sight draft and, unless
otherwise agreed by Sublandlord, shall permit Sublandlord to make presentment thereunder at an office of the bank located in the City
of New York. In each case, the Letter of Credit shall further provide that Sublandlord may draw the full amount thereof if it is not extended
for an additional one (1) year period at least forty five (45) days prior to its stated expiration date. The final Letter of Credit issued
hereunder shall have an expiration date which is no early than ninety (90) days after the Expiration Date. Each Letter of Credit shall
be in form and substance fully satisfactory to Sublandlord.


 


(b) Whenever
Subtenant is in default under this Sublease and such default has continued after any applicable written notice has been delivered to Subtenant
and beyond any applicable cure period or whenever Sublandlord has obtained a judgment against Subtenant based on a claim arising out of
this Sublease, Sublandlord may draw the amount of such default or judgment, as the case may be, from the Security Deposit, to the extent
required for the payment of any Fixed Rent or Additional Rent or for any sum which Sublandlord may expend or be required to expend by
reason of Subtenant’s default.


 




    10


     


    

 


(c) In
the case of every use, application or retention of the Security Deposit, Subtenant shall, within three (3) days after demand, replenish
the Security Deposit to the amount which Subtenant is required to maintain hereunder and the failure to do so shall constitute an Event
of Default hereunder without any notice or cure period.


 


(d) In
lieu of the Letter of Credit, Subtenant shall have the option of submitting the Security Deposit in cash on or before the date that it
signs this Sublease; provided, however, that, in such case, Subtenant shall substitute a Letter of Credit which meets the requirements
of Paragraph 19(a) above for the cash Security Deposit within sixty (60) days after the date of this Sublease and the failure of Subtenant
to do so shall constitute an Event of Default hereunder without any notice or cure period. Sublandlord shall return the cash Security
Deposit to Subtenant immediately after its receipt of the Letter of Credit.
