(exclusive of its share of common area) is attached hereto as Exhibit A. 
 B. The Landlord desires to rent to Tenant ±5,538 square feet of the
Building inclusive of Tenant’s proportionate share of common area (“Leased Property” or “Leased Premises”), and the tenant desires to lease the same, upon the terms and conditions set forth herein.

 (E)

 (F) Intentionally Deleted. 
 (G) Duration of Term. The lease term shall expire June 30, 2009 (the “Initial Term” or “Term”). 
 4. Rentals. 
 (A) Definitions. The term
“Rent” or “Rents” shall mean all Base Rents (see subparagraph 4 (B)), and all items denominated as Additional Rent (hereinafter defined) pursuant to various provisions of this Lease. 
 (B) Base Rent. The Tenant shall pay to the Landlord the annual Base Rent of $12.50 per square foot during the Term, which is agreed to be annual
Base Rent of $69,225.00. 
 Base Rent shall be computed on the basis of the actual square feet encompassed within the Lased Premises
(±4,713 sq. ft.) plus the square feet representing the proportionate share of common area within the Building (±825 sq. ft.). Each payment of Base Rent is net to Landlord and to that end all costs, expenses and obligations of every
kind and nature whatsoever relating to the Leased Property which may arise during the term hereof (and extended term if any) shall be paid by Tenant, unless otherwise specifically set forth herein. Tenant shall pay the Base Rent in twelve
(12) equal monthly installments of $5,768.75 due on the 1st day of each calendar month during the Term. 
  

 (C) Place and Manner of Payment. All payments of Rent shall be made by the Tenant to the Landlord
without notice or demand. All Rents shall be payable at the Landlord’s address as specified above, or at such other place as Landlord may from time to time designate in writing. All Rent shall be payable by Tenant’s check or, if requested
by Landlord, by certified or bank cashier’s check or by wire transfer. Payment of Rent shall commence on the Lease Commencement Date. Rents for any partial month at the beginning or end of the lease term shall be prorated, on a daily basis. The
extension of the time for payment of any installment of Rent, or the acceptance by the Landlord of any payment of any installment of Rent, or the acceptance by the Landlord of any payment of other than of the kind or within the time herein
specified, shall not be deemed a waiver of the Landlord’s right to insist upon having all other payments of Rent made in the manner and at the time herein specified. All Rent shall be paid to the Landlord without any abatement, deduction or
set-off of any kind or nature whatever, except as herein specifically provided otherwise. 
 (D) Late Charge. Tenant acknowledges that
Landlord intends to utilize the Rent payments to pay Landlord’s mortgage lender and fund Landlord’s tax and insurance escrow and that any delay by Tenant in making its Rent payments may cause the Landlord to incur late payment penalties
and additional charges under the terms of its mortgage loan. Accordingly, Tenant shall pay Landlord a late charge of five (5%) of any payment of Base Rent or Additional Rent not received by Landlord within five (5) days of its due date.

 5. Operating Expenses and Other Charges. 
 (A) Each payment of Base Rent is net to Landlord and to that end, Tenant shall pay, in addition to the Base Rent, its proportionate share of “Operating Expenses” as hereinafter defined. Tenant’s proportional share shall be
determined through the use of formula: quotient of (a) divided by (b) times (c) equaling amount due. For the purpose of the calculation a equals the amount of floor space rented by the tenant, b equals the total amount
of rentable floor space in the Building and c the total amount of Operating Expenses. Landlord estimates the Operating Expenses upon which payments for the year 2005 will be based to be $4.14 per square foot of rentable floor space per annum.
Payments for subsequent calendar years shall be based on the prior calendar year’s actual Operating Expenses. The Landlord shall compute the amount due from the Tenant pursuant to this Paragraph, and Tenant shall pay such amount in equal
monthly installments with the Base Rent. Increases in operating expenses shall not exceed 10.0% over any prior year’s operating expenses, except in the event of a change in the existing tax abatement from the Saratoga County IDA. Landlord
represents and Tenant acknowledges that the amount of such abatement began to be adjusted in 2002. 
 (B) Following the end of each calendar
year during the lease term, Landlord shall furnish to Tenant a comparative statement (the “Statement”) certified by Landlord showing Tenant’s proportional share of the Operating Expenses during the year and the amounts paid by Tenant
attributable to such year. Any overpayment or any underpayment by Tenant shall be promptly adjusted by payment, within fifteen (15) days of the balance of any underpayment, subject to the maximum per year increase in Paragraph 5(A), for such
year by Tenant to Landlord, or by Landlord to Tenant of the balance of any overpayment for such year. 
  

 (C) “Operating Expenses” include all expenses incurred in connection with the operation of the
Building, including utilities both for common areas and for all rentable floor space in the building, subject to Paragraph 6 hereof if and when utilities are separately metered (all power sources such as gas and electric necessary for power, light,
heating and cooling of the Building), water and sewer rents, State, County, City and School Taxes and any other governmental charges and assessments, including payments in lieu of taxes, payable due to the ownership and/or operation of the Building
(but excluding all income taxes or sales taxes therefrom), insurance (including but not limited to fire and extended coverage, rent abatement or rent interruption, general liability with umbrella coverage, workman’s compensation), snow removal,
ground maintenance, maintenance and service contracts, materials and replacement parts, plumbing service, license, permit and inspection fees (except for new construction or alterations), and salaries of personnel engaged in administration,
operation and maintenance of the Building, including payroll taxes and other fringe benefits related thereto, administration and management costs (being 5% of gross rents). Notwithstanding Paragraph 5(A) above, in the event that there is a
disproportionate use of utilities by any tenant of the Building, each tenant’s share of such utilities shall be based upon an independent engineering study of such use, as opposed to such tenant’s proportionate share of leased space of the
Building. To the extent that any component of Operating Expenses is directly allocable to any single suite or suites in the Building, whether by separate meter, direct payment or otherwise, the Operating Expenses and Tenant’s proportionate
share shall be adjusted accordingly. Notwithstanding anything contained in this Lease to the contrary, Operating Expenses shall not include any of the following expenses: (a) repairs or other work occasioned by fire, windstorm or other casualty
of an insurable nature or by the exercise or eminent domain; (b) leasing commissions, attorneys’ fees, costs and disbursements and other expenses incurred in connection with negotiations or disputes with tenants, other occupants, or
prospective tenants or occupants; (c) renovating or otherwise improving or decorating, painting or redecorating space for tenants or other occupants of the Building; (d) Landlord’s cost of electricity and other services that are sold
to tenants and for which Landlord is entitled to be reimbursed by tenants as an additional charge or rental over and above the basic rent payable under the lease with such tenant; (e) costs incurred by Landlord for alterations or improvements
which are considered capital improvements or replacements under generally accepted accounting principles, except where such capital improvements or replacements under generally accepted accounting principles, except where such capital improvements
or replacement results in a net reduction in Operating Expenses after the cost of the improvement or replacement is amortized and charged to Tenant over the useful life of the improvement or replacement; (f) depreciation and amortization except
as provided above; (g) expenses in connection with services or other benefits of a type which are not provided Tenant but which are provided to another tenant or occupant; (h) costs incurred due to violation by Landlord or any tenant of
the terms and conditions of any lease; (i) interest on debt or amortization payments on any mortgage or mortgages, and rental under any ground or underlying lease or leases; (j) any costs, fines or penalties incurred due to violations by
Landlord of any governmental rule or authority; (k) wages, salaries, or other compensation paid to any executive employees above the grade of building superintendent; (l) costs incurred in the removal of asbestos or other substances
considered to be detrimental to the health or the environment of occupants of the Building; (m) costs associated with compliance with general building codes, which codes were enacted prior to Tenant’s occupancy, whether such work is
performed before or after the Lease Commencement Date; (n) 
  

 costs which are reimbursed to Landlord by insurance proceeds or any other third party (except other tenants’ share
of Operating Expenses; and (o) costs incurred by Landlord in connection with selecting and effecting a change to any new utility provider, except where such change results in a net reduction in Operating Expenses after the costs of such change
are amortized and charged to Tenant in accordance with generally accepted accounting principals. The Landlord will make a “best effort” to secure continued tax abatement from the Saratoga County IDA. 
 (D) Landlord shall keep all its books and records upon which the Statement is based and make all calculations in connection therewith in accordance with
generally accepted accounting principles consistently applied. 
 6. Tenant’s Operating Expenses. At such time, if any, as Landlord determines to
separately meter utilities, Tenant shall arrange for all utility meters for the Leased Premises to be placed in its name for its account. Prior thereto, Tenant shall pay its pro-rate share of electrical and other utility usage as a component of
Operating Expenses under Paragraph 5 hereof. The Tenant shall be solely and separately responsible for payment of all separately metered electrical, gas and heating oil charges, and Tenant shall also be responsible for janitorial services for the
Leased Premises. Normal office trash only shall be placed in the dumpster provided by Landlord. Large packaging and similar materials shall be Tenant’s obligation to remove and shall not be placed in the dumpster. Tenant shall maintain the
thermostat setting in the Leased Premises at a minimum of 55E to prevent water lines located inside the Building from freezing and to prevent other temperature related damages. 
 7. All Sums Denominated Additional Rent. All taxes, charges, costs and expenses which the Tenant is required to pay or reimburse the Landlord (in whole or in part) under this Lease, together with all interest
and penalties that may accrue thereon, and all damages, costs and expenses which Landlord may incur by reason of any default or other failure on Tenant’s part to comply with the terms of this Lease, shall be deemed to be Additional Rent and, in
the event of non-payment by Tenant, Landlord shall have all the rights and remedies with respect thereto as the Landlord has for the non-payment of base rent. Landlord represents and warrants that the HVAC and electrical services for the Leased
Premises are in good working order and that to the best of Landlord’s knowledge, the Building is in compliance with the New York State Uniform Fire Protection and Building Code.

Tenant that the roof previously leaked and Landlord has previously repaired the roof and the Landlord agrees to further maintain in good order and repair the roof, roof covering, exterior walls, plumbing, electrical, HVAC, and other major building
systems and other structural components of the Building, and to repair the Tenant’s rentable space as necessary, at the sole expense of Landlord, to the reasonable satisfaction of Tenant, if the need for repair to Tenant’s rentable space

	17.	Alterations and Improvements. 

 (A)
Landlord’s Consent. Tenant shall have the right to make changes and non-structural alterations, additions or improvements in or to the Leased Property so long as the same do not affect the electrical or mechanical systems of the
Buildings. Tenant shall not make, or cause or permit the making of, any structural alterations, additions or improvement, (or otherwise affect the electrical or mechanical systems) including demolition and rebuilding in or to the Leased Property
without obtaining Landlord’s prior written consent thereto in each instance. Plans and Specifications showing the proposed structural alterations, additions and improvements shall be submitted to Landlord for approval as part of the application

 (D) Permits. No alterations or improvement shall be undertaken
until the Tenant has procured and paid for all required permits and authorizations from the appropriate governmental unit(s). 
  

 8 

 (E) Improvements Become Landlord’s Property. As to any alteration or improvement which
Landlord does not require to be removed by Tenant at the expiration of the lease term, (Landlord shall notify Tenant of any obligation to so remove in writing no later than 120 days prior to the expiration of the term) the components of such
alteration or improvement shall become the absolute property of Landlord at the expiration of the lease without payment of any consideration herefore unless such alteration or improvement is readily portable and Tenant desires to remove same, in
which case Tenant may do so. Tenant shall have the option to remove any improvements and restore the Leased Property to its original condition at Tenant’s sole cost, provided such removal is completed in the time and manner required under
Paragraph 16. 
 (F) Additional Conditions to Alterations. Before making final payment with respect to any permitted work, the Tenant
shall deliver to Landlord written waivers of lien by any architect, engineer, contractor, materialman, laborer or other persons supplying materials or labor in connection with the improvement or alteration whereby such person waives any lien upon or
against the Leased Property, or the Building, or the interest of the Landlord therein. 
 (G) Removal of Liens. Tenant shall not
permit any mechanic’s lien or other similar lien to be filed against the Leased Property or the Building or against the Landlord’s interest in the same by reason of any work, labor, services or material supplied for any alteration or
improvement or other work performed by or on behalf of Tenant in connection with the Building or the Leased Property. If any lien shall at any time be filed against the Leased Property, Tenant shall, within thirty (30) days after written notice
from Landlord, cause such lien to be discharged of record, by payment, deposit, bond or court order. If Tenant fails to discharge such lien with in such thirty (30) day period, then, in addition to (and not in lieu of) any other right or remedy
of the Landlord, the Landlord may, but shall not be obligated to, discharge such lien either by payment, deposit, bond, court order or otherwise. In such event, Landlord shall be entitled to be reimbursed by Tenant for any payment made to
satisfy or discharge such lien (including, without limitation, legal costs and expenses and bond premiums) together with interest thereon at the prime rate of Key Bank of New York plus three (3%) percent per annum, computed as to each item from
the date of payment by Landlord. All such sums shall be construed as additional rent. Nothing in this paragraph shall be construed in any way as constituting the consent or request of the Landlord, express or implied, by inference or otherwise, to
any contractor, subcontractor, laborer or materialman for the performance of any labor or the furnishing of any materials for any specific improvement, alteration, or repair of or to the Leased Property, or as giving the Tenant the right, power or
authority to contract for or permit the rendering of any service for the furnishing of any material without the Landlord’s prior written consent as provided above. 
  

	18.	Landlord Rights Upon Tenant’s Default. 

 (A)
Definition of Default. A “default” is defined as follows: 
 (1) If the action or proceeding is commenced by or against the
Tenant under the federal bankruptcy laws or any other federal or state insolvency laws, and the same is not discharged within sixty (60) after commencement. 
  

 9 

 (2) If any trustee, receiver, or committee for the benefit of creditors is appointed for Tenant or
Tenant’s property and the same is not discharged within sixty (60) days after appointment. 
 (3) If Tenant failed to pay any Rent
or any other monetary obligation under this Lease and such failure is not cured within (10) days after written notice of default. 
 (4) If this Lease is assigned or the Leased Property or any portion thereof is sublet, other than in accordance with the terms and conditions of the Lease Agreement and such default is not cured within thirty (30) days after written
notice. 
 (5) If the Tenant ceases to conduct business in the Leased Propety or allows same to become vacant for more than thirty
(30) consecutive days. 
 (6) If Tenant fails to maintain the insurance policy and coverages(s) required herein. 
 (7) Intentionally Deleted. 
 (8) If
Tenant defaults in the performance of any other term of provision of this Lease and such default is not cured within thirty (30) days after written notice of default. If it is not reasonably possible to completely cure any such default within
such thirty (30) day period, a default shall be deemed to exist if Tenant fails to commence a cure within thirty (30) days or fails to diligently prosecute such cure after timely commencement. If such default by Tenant also constitutes an
event of default by Landlord under any mortgage affecting the Building, and such mortgage contains shorter cure periods, the shorter time periods shall control. 
 (B) Tenant’s Responsibilities on Default. In the event of any default by Tenant, re-entry by Landlord, expiration or termination of the Lease or dispossess by summary proceeding or otherwise, Tenant shall
be responsible for the following: 
 (1) Rent up to time of such re-entry, dispossess, expiration or termination of this Lease. 

(2) The Present Value of Rent for the balance of the full term, all of which may, at Landlord’s option, be accelerated by Landlord and made due
and payable as of the date of re-entry by Landlord, termination of the Lease or entry of a judgment of possession, whichever date first occurs. If Landlord exercises such option, the Present Value (hereinafter defined) of all such sums shall become
immediately due and payable as of the date on which Landlord notifies Tenant of Landlord’s exercises of its option to accelerate as hereinabove provided, together with all sums past due. As used herein, the term “Present Value” means
the present value of all sums due under the terms hereof after the date of re-entry by Landlord, termination of this Lease or entry of a judgment by possession, whichever date first occurs, discounted at the rate of eight (8%) percent per
annum. 
  

 10 

 (3) The payment of all reasonable sums incurred by Landlord in putting the Premises in good order or
preparing the same for re-rental, including brokerage and advertising; 
 (4) Reasonable attorney’s fees and expenses resulting from
Landlord enforcing any of the remedies described below, or in the enforcement of this Lease or in defending and claim brought against Lessor by Lessee against which Lessor successfully defends; and 
 (C) Landlord’s Remedies on Default. Upon the occurance of any default, Landlord shall have the right to declare the lease term to have come
to an end, and the Landlord shall have the following rights and remedies, in addition to (and not in lieu of any other rights or remedies Landlord may have at law): 
 (1) Re-Entry. To reenter or repossess the Leased Property, either by force, eviction proceedings, summary proceedings, surrender or otherwise, or to dispossess and remove the Tenant and other occupants, and
their property and effects. 
 (2) Injunctive Relief. Landlord shall be entitled to enjoin breach by the Tenant of any of the terms
and conditions in this Lease and in such event shall also be entitled to a preliminary injunction, temporary restraining order, or similar provisional relief. 
 (3) Damages. Landlord may seek monetary damages in any re-entry or summary proceeding, or commence a separate action or special proceeding against Tenant and any other responsible parties, to recover monetary
damages accruing by reason of any default, together with interest, plus all reasonable attorney’s fees, disbursements, court costs and other reasonable expenses incurred in connection therewith. Monetary damages shall include, without
limitation, Base Rent and all Additional Rent due at the time proceedings are commenced, rent shortages accruing thereafter as set forth in subparagraph (D) below, plus all costs associated with any reletting of the Leased Property. Landlord is
under no obligation to mitigate its damages. 
 (4) Remedies Not Exclusive. Mention in this Lease of any particular remedy shall not
preclude Landlord from any other reasonable remedy, at law or in equity, it being agreed that the rights and remedies of Landlord are cumulative. 
 (D) Reletting. Landlord may attempt to re-let the Leased Property, 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. The Landlord may grant concessions in connection with such re-letting. Tenant shall also pay Landlord, as liquidated damages, the deficiency between the rents and additional rents reserved under this Lease and the rents collected or to be
collected on account of the lease or leases of the Leased Property for the remaining period which would otherwise have constituted the balance of the term of this Lease. In computing such damages there shall be added to the deficiency such expenses
as Landlord may reasonably incur in connection with re-letting. Any such damages shall be paid from time to time upon demand after transmittal by Landlord of its calculations of the amount then due. 
  

 11 

 Landlord, at Landlord’s option may make such alterations, repairs, replacements and/or decorations in the Leased
Property as Landlord, in Landlord’s sole judgment, considers advisable and necessary for the purpose of re-letting the Leased Property. 
 (E) Waiver of Redemption. Tenant hereby expressly waives any statutory notice of intention to re-enter or of institution of legal proceedings for purposes of re-entry. Tenant further waives any and all rights to redeem under
Section 761 of the New York Real Property actions and Proceedings Law, and under any other present or future law creating any right of redemption or similar rights in favor of tenants. 
  

	19.	Aggrieved Party’s Right to Perform Other’s Obligations. 

 (A) Right to Cure. If either party defaults, and the default is not timely cured, after notice, the other party shall have the option to cure such default on the other’s behalf, in which event such
defaulting party shall reimburse the aggrieved party for all sums paid to effect such cure, plus interest at a rate equal to the highest prevailing prime rate charged by Key Bank of New York plus three percent (3%), calculated from the date of such
payment, together with all reasonable professional fees, costs, and other expenses incurred in connection therewith. If payable by Tenant, all such sums shall be deemed additional rent hereunder. 
 (B) Notice to Landlord. Landlord shall in no event be charged with default in any of its obligations hereunder unless and until Landlord shall
have failed to perform such obligations within thirty (30) days (or such additional time as is reasonably required to correct any such default) after written notice to Landlord by Tenant, specifically describing such failure. If Landlord
commences within such thirty (30) day period and proceeds with due diligence to remedy a defect or to make any change required under this Lease, it shall not be in default. 
 (C) Notice to Mortgagee. If the holder of any mortgage covering the Leased Property shall have given written notice to Tenant of the address to
which notices to such holder are to be sent, Tenant shall give such holder written notice simultaneously with any notice given to Landlord of any default of Landlord, and if Landlord fails to cure any default asserted in said notice within the time
provided above, Tenant shall notify such holder in writing of the failure to cure, and said holder shall have thirty (30) days after receipt of such second notice to cure such default before Tenant may take any action by reason of such default.

 (D) Liability of Mortgagee. No mortgagee, or its nominee, shall become liable under the provisions of this Lease unless and until
such time as it becomes, and then only for so long as it remains, the owner of the Landlord’s interest in this Lease, and such liability shall be limited solely to such mortgagee’s or nominee’s interest in the Property. 
 (E) Liability of Landlord. Tenant shall look only to the Landlord for the satisfaction of Tenant’s remedies for the collection of a judgment
(or other judicial process) regarding the payment of money by Landlord in the event of any default by Landlord hereunder. The Landlord’s partners or principals (disclosed or undisclosed) shall not be subject to levy, execution or other
enforcement procedure for the satisfaction of Tenant’s remedies under or with respect to this Lease, the relationship of Tenant and Landlord or Tenant’s use and occupancy of the Leased Property.

 (A)
Landlord and Landlord’s agents, employees, and representatives may enter upon the Leased Property upon reasonable prior notice at all reasonable times, to inspect it, to perform any work which Landlords elects or is required to undertake, or to
perform any work made necessary by reason of the Tenant’s default under the Lease, and may also exhibit the Leased Property in connection with efforts to sell, lease (within the last six (6) months of the Term), or obtain financing for the
Building, provided that such access does not unreasonably interfere with Tenant’s use of the Leased Property. Landlord’s right of entry shall not be deemed to impose upon Landlord any obligation or liability for the care, supervision or
repair of the Leased Property other than expressly provided in this Lease. 
 (B) Landlord shall provide Tenant with keys for all door locks
providing entry to the Building. Tenant shall provide Landlord with keys for all interior lockable doors, providing access to or within the Leased Premises upon request by Landlord. Tenant shall not change such locks without Landlord’s written
consent. 
 (C) The making of any repairs which Landlord is required or permitted to make under this Lease shall not constitute an eviction
of Tenant in whole or in part and the rent reserved shall in no way abate, while such repairs or alterations are being made, but such repairs shall be made as expeditiously as reasonably possible, and be conducted so as to minimize any unreasonable
interference with Tenant’s business. 
  

	21.	Condemnation, Damage and Destruction. 

 (A)
Restoration Time. 
 (1) Within fifteen (15) days from the date of any fire or casualty, the Landlord shall obtain from any
reputable A.I.A. architect, a certification certifying in his/her opinion the time within which the Leased Property and the reasonable access thereto can be restored and reconstructed under standard building conditions (hereinafter called the
“Restoration Time”). Landlord shall deliver such certification to the Tenant, and in the event the damages be so substantial the Leased Property cannot be restored within one hundred twenty (120) days from the date of Landlord’s
receipt of the insurance proceeds, from such fire or casualty, based on the certified Restoration Time hereinabove referred to, then, in that event, either the Landlord or the Tenant shall have the right (a) within thirty (30) days after
receipt of such notice to advise the other that it elects to terminate the Lease; or (b) that it requires Landlord to prosecute restoration of the Leased Property in the manner hereinafter provided. In the event the Landlord or Tenant shall
elect to terminate the Lease, Tenant shall surrender the Leased Property forthwith provided that is shall continue to pay pro rata net annual Base Rent and additional rent for any portion of the Leased Property which it continues to occupy and
conduct business from pending such surrender of the Leased Property. 
  

 13 

 (2) Restoration. In the event this Lease is not terminated in accordance with Section 21
(A) (1) above, the Landlord shall undertake to restore the Leased Property substantially to the condition prior to the fire or casualty subject to then applicable law, with reasonable speed and dispatch, and Landlord shall diligently
prosecute reconstruction in order to restore the Leased Property for Tenant’s use as expeditiously as possible. 
 (3) Rent
Abatement. To the extent the Leased Property is unusable for the conduct of business by Tenant after the casualty, Tenant’s obligation to pay rent shall abate and Landlord shall look to the rent insurance provided by Tenant as required
hereunder. 
 (B) Condemnation or Taking. If there shall be a taking of all or a material portion of the Leased Property or the
reasonable access thereto by federal, state, county, city or other authority for public use, or under any statute, or by right of eminent domain (a “Taking”), then this Lease shall terminate as of the date of the Taking and the rent shall
be adjusted as of the date of such termination of this Lease. A Taking of a material portion of the Leased Property shall be deemed to mean a taking of such scope that the untaken portion of the Leased Property is insufficient to permit the
restoration of the then existing improvements thereof so as to constitute a complete operating facility of sufficient size to permit Tenant to conduct its business in substantially the same manner as prior to the Taking. 
 (C) Partial Taking. If there shall be a partial Taking of the Leased Property which shall not result in a termination of this Lease as provided in
Section 21 (B), then Landlord shall, at its own cost and expense, restore the remaining portion of the Leased Property within ninety (90) days from such partial Taking and the rent shall be equitably apportioned according to the space
taken. 
 (D) Awards. All compensation awarded or paid upon such a total or partial Taking of the Leased Property shall belong to and
be the property of the Landlord without any participation by the Tenant; provided, however, that Tenant shall not be precluded from prosecuting any claims directly against the condemning authority for moving expenses or other awards specifically set
aside for tenants of the Building, including damages for the taking of the Tenant’s leasehold interest, provided that Landlord’s award for damages in the Taking is not reduced or diminished. 
 (E) No Obligation. Anything in this Paragraph 21 to the contrary notwithstanding, it is expressly understood and agreed that Landlord shall not be
obligated, in its sole discretion, to repair or replace the Building, in the event that insurance or condemnation proceeds are retained by the mortgagee of the first lien or such fire, casualty or condemnation shall occur during the last year of the
Initial Term or any renewal term. In such event, at either Landlord’s or Tenant’s option this Lease shall be terminated and deemed null and void and of no further force and effect, and both parties shall be released of liability one to the
other, except as otherwise in the Lease provided. Landlord and Tenant agree to execute at the request of the other a lease termination agreement in recordable form to evidence the Lease termination. 
  

 14 

 22. Tenant’s Insurance. Tenant shall carry Commercial General Liability Insurance (1986 Form) written on an
occurrence form for the duration of this Lease. Such insurance shall cover the Leased Premises and the Tenant’s contractual obligations as stipulated in this Lease. The Commercial General Liability policy shall reflect the interests of the
Landlord as an additional insured. 
 Such insurance shall be provided in amounts not less than: 
  

			
	 Coverage
	  	Limits of Liability
	 General Aggregate Limit
	  	$2,000,000
	 Products/Completed Operations Aggregate Limit
	  	$2,000,000
	 Personal/Advertising Injury Occurrence Limit
	  	$2,000,000
	 Each Occurrence Limit
	  	$2,000,000
	 Fire Damage (any one fire)
	  	$300,000
	 Medical Expenses (any one person)
	  	$5,000

 Prior to occupying the Leased Premises, Tenant shall provide a Certificate of Insurance to the
Landlord evidencing coverages in compliance with the above requirements. The Certificate of Insurance shall provide thirty (30) days advance written notice (if reasonably available) to the Landlord in the event of the cancellation, change
and/or non-renewal of the coverages certified. The Certificate of Insurance shall be renewed and filed with the Landlord annually for the duration of this Lease. A copy of the Certificate of Insurance shall be provided to Landlord upon thirty
(30) days written notice. 
  

	23.	Intentionally Deleted. 

  

	24.	Assignment and Subletting, Change in Control. 

 (A)
In General. The Tenant may not, voluntarily or by operation of law, assign, sublet, mortgage or encumber this Lease, for all or any portion of the remainder of this term, or permit a change in control of Tenant or permit a transfer of
substantially all of the assets of Tenant without the express prior written consent of the Landlord in each instance which consent shall not be unreasonably delayed, conditioned or withheld. The Tenant shall remain primarily liable for the rent
reserved in this Lease Agreement and the performance of all of its terms and conditions notwithstanding any such assignment or subletting, or change in control or transfer of assets. The collection or acceptance of any rent or additional rent by the
Landlord shall not be deemed a waiver of this covenant, or the acceptance of the assignee, subtenant or occupant as a tenant, or release of the Tenant from the further performance of the terms and conditions of this Lease. Landlord’s consent to
an assignment or sublease or change in control or transfer of assets shall not be construed to relieve Tenant from obtaining Landlord’s written consent for any further 
  

 15 

 
assignment or sublease. Change in control shall mean the transfer of 51% or more of the voting stock of Tenant or any Guarantor after the date hereof in one
or more of a series of transactions, whether by sale of stock, merger, liquidation, or other transfer. 
 (B) Tenant may assign or otherwise
transfer its rights and delegate its duties or obligations under this Agreement without the consent of the Landlord (i) to a wholly-owned affiliate, provided that Tenant shall remain liable for all obligations under this Lease notwithstanding
such assignment or other transfer to its wholly-owned affiliate, or (ii) in connection with change in control or a sale or other transfer of all, or substantially all, of its assets through merger. 
 (C) Instruments of Assignment. No assignment or subletting or change in control of Tenant or transfer of assets of Tenant shall be valid or
effective until there is delivered to Landlord a duplicate original of the written instrument of assignment or sublease containing the name and address of the assignee or subtenant and an express assumption by the assignee or subtenant or new
principals of Tenant or new owner of the assets of Tenant of this Lease Agreement and of all of the obligations under this Lease to be performed by the Tenant. 
 (D) Instruments of Subletting. Any sublease(s) consented to by Landlord must provide that Tenant (as sublandlord) assigns all rents under the sublease to Landlord and in the event of default by Tenant hereunder
upon written notice from Landlord all rents under such sublease(s) shall be paid by the subtenants to Landlord. 
  

	25.	Subordination and Attornment. 

 (A) Tenant
recognizes that Landlord has financed all or part of the construction costs of the Building through financing which is secured by mortgages or similar encumbrances upon the land and the Building. In addition, Landlord may obtain IDA financing
involving the execution and delivery of deed(s), leases, bond(s), mortgage(s) and an installment sale agreement. This Lease Agreement shall be subject and subordinate to any lease, sale agreement and mortgage(s) given to secure the financing and any
other mortgage now or hereafter constituting a lien upon the Leased Property, and to all additions, increases, renewals, modifications, consolidations, replacements or extensions thereof. Although no instrument or act on the part of the Tenant shall
be necessary to effectuate such subordination, the Tenant agrees to execute, acknowledge and deliver such further commercially reasonable instruments subordinating this Lease to such lease or sale agreement and mortgage. However, Landlord agrees to
cause the IDA sale agreement and mortgage, or any other sale agreement or mortgage, and all other financing instruments to provide that the Lender shall not have any right to terminate this Lease, so long as Tenant is not in default under this Lease
beyond any applicable notice and cure period. 
 (B) In the event of the cancellation or termination of the sale agreement, including any
extensions or renewals, or in the event of the foreclosure of any mortgage, the Tenant shall makefull and complete attornment to the IDA and/or other lender for the balance of the term of this Lease, upon the same covenants and conditions as are
contained herein, so as to establish direct privity of estate and contract between IDA and/or other lender and the Tenant with the same force and effect as though this Lease Agreement were originally made directly between them. The Tenant shall
thereafter make all rent payments directly to the IDA or to the other lender, as the case may be. 
  

 16 

 26. Fees and Expenses. Should either party hereto commence an action against the other to enforce any obligation
under this Lease, the prevailing party shall be entitled to recover reasonable attorneys’ fees and expenses from the other. 
  

	27.	Indemnification. 

 (A) Indemnification by
Landlord. Landlord hereby agrees to indemnify, defend and hold harmless Tenant, its successors, assigns, subsidiaries, directors, officers, agents and employees from and against any and all damage, loss, liability or expense including, but not
limited to, reasonable attorneys’ fees and legal costs, suffered by same directly or by reason of any claim, suit or judgment brought by or in favor of any person or persons for damage, loss or expense due to, but not limited to bodily injury,
including death arising at any time therefrom, and property damage sustained by such person or persons which arises out of, is occasioned by or attributable to the acts or omissions of Landlord, its licensees, concessionaires, agents, employees or
contractors (“Landlord Employees”), or any breach or default in the performance of any obligation on Landlord’s part to be performed under the terms of this Lease, except to the extent caused by the negligence or the willful
misconduct of Tenant, its employees and agents. If any proceeding is brought against Tenant by reason of any such claim, Landlord shall defend same at Landlords’ expense by counsel satisfactory to Tenant. 
 (B) Indemnification by Tenant. Tenant hereby agrees to indemnify, defend and hold harmless Landlord, its successors, assigns, subsidiaries,
directors, officers, agents and employees from and against any and all damage, loss, liability or expense including, but not limited to, reasonable attorney’s fees and legal costs, suffered by same directly or by reason of any claim, suit or
judgment brought by or in favor of any person or persons for damage, loss or expense due to, but not limited to, bodily injury, including death arising at any time therefrom, and property damage sustained by such person or persons which arises out
of, is occasioned by or attributable to the use or occupancy of the Leased Premises by Tenant, the acts or omissions of Tenant, its subtenants, licensees, concessionaires, agents, employees or contractors (“Tenant Employees”), or any
breach or default in the performance of any obligation on Tenant’s part to be performed under the terms of this Lease, except to the extent caused by the negligence or willful misconduct of Landlord, its employees and agents. If any proceeding
is brought against Landlord by reason of any such claim, Tenant shall defend same at Tenant’s expense by counsel satisfactory to Landlord. 
 (C) Survival. The foregoing indemnities shall survive the expiration of the Term or any other termination of this Lease. Notwithstanding the foregoing, Landlord and Tenant agree that neither party hereto is indemnifying the other for
the acts of third parties who are not Landlord Employees (for whom Landlord shall bear responsibility) or Tenant Employees (for whom Tenant shall bear responsibility). Each party’s agreement to indemnify and hold the other party harmless
pursuant to the foregoing is not intended to and shall not relieve any insurance carrier of its obligations under policies required to be maintained under this Lease by Tenant or Landlord, with the indemnitor in each such case having the right to
the benefit of any available insurance proceeds as a setoff and/or mitigation of any indemnity amounts paid. 
  

 17 

 (D) Limitation of Liability. Neither party shall be liable to the other party for special or
consequential damages as a result of any breach of any provision of this Lease or any negligent act or omission. 
 (E) Subrogation.
Upon either party’s fully assuming and performing its obligations as set forth in subparagraph (A) or subparagraph (B) hereof, whichever is applicable, such party (the “Indemnifying Party”) shall be subrogated to any rights
of the other party (the “Indemnified Party”) against any third parties. The Indemnified Party shall promptly notify the Indemnifying Party of any claim asserted against the Indemnified Party on account of any injury or claimed injury to
persons or property and shall promptly deliver to the Indemnifying Party the original or a true copy of any summons or other process, pleading, or notice issued in any suit or other proceeding to assert or enforce any such claim. The Indemnifying
Party shall have the duty to defend any such suit, to the extent of its indemnification as set forth in subparagraph (A) or (B) above whichever is applicable, is applicable thereto. 
 (F) Insurance. The Indemnifying Party’s obligation to indemnify the Indemnified Party hereunder shall only apply to the extent any liability,
loss or expense incurred by the Indemnified Party (including reasonable attorneys’ fees) is not covered by insurance maintained by Indemnified Party. 
 28. Waiver of Subrogation. Without affecting any other rights or remedies, each party to this Lease herby releases and relieves the other party (including such other party’s officers, directors, agents, representatives,
employees, affiliated corporations, partners, managers, successors and assigns) and waives its right to recover damages (whether in contract or tort) against such other party (and such other party’s officers, directors, agents, representatives,
employees, affiliated corporations, partners, managers, successors and assigns), for any and all losses and damages to the waiving party, or to any property of the waiving party, arising out of or incident to any peril covered by insurance
maintained by the waiving party, arising out of or incident to any peril covered by insurance maintained by the waiving party as required by the terms in this Lease, but only to the extent of such insurance. Each party to this Lease agrees to cause
its insurer(s) to include a waiver of subrogation rights provision in the policies of insurance required to be maintained pursuant to this Lease. 
 29.
Notices. Any notice, consent or request required or permitted under this Lease Agreement shall be in writing and will be deemed sufficiently given if delivered personally or sent by registered or certified mail, return receipt requested, to
the respective parties at the following addresses:

	30.	Modification and Waivers: 

 (A) No Oral
Modifications or Discharge. This Lease Agreement may not be discharged or terminated, nor may it be changed, modified or supplemented orally, but only by a document in writing, signed by both Landlord and Tenant. 
 (B) Modification at Request of Mortgage Lenders. If, in connection with obtaining temporary or permanent financing for any portion of the Leased
Property, any lender shall request reasonable modifications of the Lease as a condition to such financing, Tenant agrees that Tenant will not unreasonably withhold, delay or defer the execution of a modification agreement, provided such
modifications do not increase the financial obligations of tenant hereunder or materially adversely affect the leasehold interest hereby created or Tenant’s reasonable use and enjoyment of the Leased Property. 
 (C) No Waiver by Implication: No Oral Waivers. The failure of either party to seek redress for any default, or to insist upon the strict
performance of any covenant or condition of this Lease shall not constitute an implied waiver, and shall not prevent any subsequent act or omission from having all the force and effect of any original default. The receipt by Landlord of rent or
payment of rent by Tenant with knowledge of the breach of any covenant of this Lease shall not be deemed a waiver of such breach. No provision of this Lease shall be deemed to have been waived by either party, unless such waiver be in writing signed
by such party. 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 on any check or
any letter accompanying any check or payment as rent be deemed an accord 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. 
 31. Security Deposit. The Tenant will deposit the sum of zero (0) month’s Base Rent and Additional Rent contemporaneously
with execution of this Lease, as security for the full and faithful performance by the Tenant of all of the terms, covenants and conditions of this Lease upon the Tenant’s part to be performed. Provide that Tenant is not in default under any of
the terms and provisions of this lease, the security deposit shall be returned to Tenant; otherwise, it shall be used to restore the Leased Premises to the condition required by the terms of this Lease or otherwise applied against Tenant’s
obligations in the event of a default. 
  

 19 

 32. Memorandum of Lease. The Lease Agreement shall not be recorded. Landlord and Tenant shall, at the request of
either party, execute and deliver a memorandum of this Lease Agreement in proper form for recording, but the memorandum shall not in any circumstances be deemed to modify or change any of the provisions of this Lease Agreement, the provisions of
which shall in all instances prevail. 
 33. Estoppel Certificates. Each party agrees at any time, and from time to time, upon not less than fifteen
(15) days prior notice by the other party, to execute, acknowledge, and deliver to the other party, a statement in writing certifying (or, if there have been modifications, that the same is in full force and effect as modified and stating the
modifications) stating the dates to which the fixed base rent and additional rent have been paid, and stating whether or not to the best knowledge of the signer, there exists any default beyond any applicable notice and cure period by the other and,
if so, specifying each such default. It is the parties intent that any such statement delivered pursuant hereto may be relied upon by the other party and by any mortgagee or prospective mortgagee of any mortgage affecting the Building or
Tenant’s interest in this Lease, and by any subtenant or assignee. 
 34. Environmental Matters. Insofar as they are applicable to Tenant’s
use of the Leased Premises, Tenant shall comply with all environmental laws, which include all federal, state, local and municipal laws, statutes, ordinances, rules, regulations, orders, decrees or requirements for regulating relating to, or
imposing liability or standards of conduct concerning the use, storage, treatment, transportation, manufacture, refinement, handling, production and disposal of all waste generated on the Leased Property, hazardous materials covered by any
Environmental Law, or otherwise pertaining to environmental protection, as now or at any time hereafter in effect, including, but not limited to, the Comprehensive Environmental Response, Compensation and Liability Act, 42 U.S.C. Section 9601;
the Superfund Amendment and Reauthorization Act of 1986, Public Law 99-499, 100 Stat. 1613; Toxic Substances Control act of 1976; the Resource Conservation and Recovery Act, 42 U.S.C. Section 6901; the Occupational Safety and Health Act, 29
U.S.C. Section 655 and Section 657; the Clean Air Act, 42 U.S.C. Section 7401; the Clean Water Act, 33 U.S.C. Section 1251; the New York State Environmental Quality Review Act, New York State Environmental Conservation Law,
Section 8-1101; the New York Environmental Conservation Law, together with all amendments thereto, substitutions therefore, rules and regulations promulgated thereunder and all amendments to and substitutions for the rules and regulations (the
aforementioned are called the “Environmental Laws”). Tenant shall defend, indemnify and hold harmless the Landlord and the Landlord’s employees, agents, partners, officers, directors and trustees from any and against any and all
claims, demands, penalties, fines, liabilities, settlements, damages, costs and/or expenses of whatever kind or nature and/or any other environmental clean-up of any kind or description, known or unknown, contingent or otherwise, arising out of or
in any way relating to any violation of any Environmental Laws arising out of Tenant’s use of the Building and Leased Property and caused by Tenant, its employees, contractors, invitees or such other persons under Tenant’s control.
Landlord represents to Tenant that to the best of Landlord’s knowledge, as of the date hereof there are no material violations of any environmental law or any of the above cited statutes. Notwithstanding the foregoing, Tenant shall have the
right to use and store at the Leased Property in compliance with applicable laws reasonable quantities of office products and cleaning supplies.

	35.	Construction and Miscellaneous. 

 (A) Governing
Law. This Lease shall be governed by, and construed and enforced in accordance with, the laws of the State of New York. 
 (B)
Grammatical Usage. In construing this Lease, feminine or neuter pronouns shall be substituted for those masculine in form, and vice versa, and plural terms shall be substituted for singular and singular for plural, in any place in which the
context so requires. 
 (C) Terms Inclusive. The term “Landlord” and “Tenant” shall include the parties named in
this Lease, their legal successors in interest, and all permitted subtenants or assigns. 
 (D) Captions. Captions are inserted in the
Lease only as a matter of convenience and for reference and in no way define, limit or describe the scope of intent of this Lease Agreement or in any way affect this Lease. 
 (E) Severability. If any term or provision of this Lease shall, to any extent, be declared to be invalid or unenforceable, the remainder of this
Lease shall not be affected thereby and the balance of the terms and provisions of this Lease shall be valid and enforceable to the fullest extent permitted by Law. 
 (F) Counterparts. This Lease Agreement may be executed in several counterparts, and any signed counterpart shall constitute a legal original for all purposes. Any such counterparts may be introduced into
evidence in any action or proceeding without having to produce the others. 
 (G) Consent. Whenever either party’s consent or
approval shall be required herein, unless such consent or approval is expressed herein as being in the sole or absolute discretion of such party, such consent or approval shall not be unreasonably or arbitrarily withheld, conditioned or delayed, and
shall be deemed to have been given, unless within thirty (30) days of the other party’s request therefor, the party whose consent has been requested notifies the other that it is denying such consent or approval, stating in such notice the
reasonable grounds therefor. 
 (H) Intentionally Deleted. 
 (I) Force Majeure. If either party hereto shall be delayed or hindered in or prevented from the performance of any act required hereunder by
reason of acts of God, governmental emergencies, strikes, lockouts, labor troubles, inability to procure material, failure of power, restrictive governmental laws or regulations, riots, insurrection, war or other reason of a like nature not the
fault of the party delayed in performing work or doing acts required under this Lease, the period for the performance of any such act shall be extended for a period equivalent to the period of such delay. Notwithstanding the foregoing, the
provisions of this Subparagraph 

  

 21 

 
shall at no time operate to excuse Tenant from any obligations for payment of Rent, or any other payments required by the terms of this Lease when the same
are due, and all such amounts shall be paid when due, except as otherwise expressly provided in this Lease. 
 (J) Further Action. The
parties shall execute and deliver all documents, provide all information and take or forbear from all such action as may be necessary or appropriate to achieve the purpose of this Agreement. 
 (K) Exclusive Agreement. This Lease Agreement constitutes the entire agreement between the parties pertaining to the subject matter hereof and
supersedes all prior agreements and understandings pertaining thereto. No covenant, representation or condition not expressed in this Lease shall affect, or be deemed to interpret, change or restrict the express provisions hereof. 
 (L) Trial by Jury. It is mutually agreed between the Landlord and the Tenant that each of them shall, and hereby does, waive trial by jury in any
action, proceeding or counterclaim brought by either of the parties against the other on any matters whatsoever arising out of, or in any way connected with, this Lease, the Tenant’s use or occupancy of the Leased Property, and any claim of
injury or damage related to any of the same. 
 (M) Amendment or Termination. Except as otherwise provided herein, this Lease may be
modified or amended only with the prior written approval of both parties, and it may not be discharged or terminated except in writing. 
 (N) Authorizations and Representations. Each party hereby severally represents that it has been duly authorized to execute, deliver and perform this Lease through its members, officers or agents signing on its behalf and affixing any
appropriate seal hereto. 
 (O) Accord and Satisfaction. Landlord is entitled to accept, receive and cash or deposit any payment made
by Tenant for any reason or purpose or in any amount whatsoever, and apply the same at Landlord’s option to any obligation of Tenant and the same shall not constitute payment of any amount owed except that to which Landlord has applied the
same. No endorsement or statement on any check or payment shall affect Landlord’s right to recover any and all amounts owed by Tenant hereunder and Landlord’s right to pursue any other available remedy. 
 (P) Financing. If Landlord desires to obtain or refinance any mortgage loan, Tenant shall negotiate in good faith with Landlord concerning any
request made by any lender or proposed lender for changes or modifications in this Lease subject however to Subsection 30(B). In particular, Tenant shall agree, upon request of Landlord, to supply any such Lender with such notices and information as
Tenant is required to give to Landlord hereunder and to extend the rights of Landlord hereunder to any such lender and to consent to such financing if such consent is requested by such lender. Tenant shall provide any other consent or statement and
shall execute any and all other commercially reasonable documents that such lender reasonably requires in connection with such financing, including any commercially reasonable subordination, non-disturbance and attornment agreement, so long as the
same do not adversely affect any right, benefit or privilege of Tenant under this Lease except in any non-material respect or materially increase Tenant’s obligations under this Lease in any material respect or increase any of Tenant’s
monetary obligations under this Lease. 
  

 22 

	36.	Early Termination. 

 (A) So long as Tenant is not in default under any of the terms and provisions of this Lease and all of the terms, covenants and conditions on Tenant’s part to be performed under this Lease have been and continue
to be fully and faithfully performed for the balance of the Term, Tenant shall have the option exercisable by written notice given at any time after the end of the twelfth (12th) month following the Rent Commencement Date, to terminate this Lease effective at the end of the third (3rd) calendar month following the month in which written notice of the election is given. To be effective, Tenant’s exercise of its option to terminate
must be accompanied by (a) an Early Termination Fee equal to three (3) months of Base Rent and Operating Expenses, and (b) payment of the unamortized portion of the Landlord’s Work (the “Unamortized Portion”) as
described in Paragraph 2A and Exhibit B. Tenant’s right to terminate shall be effective as of September 30, 2006 and shall expire if such option is not exercised by giving such written notice on or before February 29, 2009. The
Unamortized Portion shall be computed by dividing the total cost of Landlord’s Work by the number of months in the original term of this Lease and multiplying the result by the number of months remaining in the Lease term as of the effective
date of Tenant’s termination notice. (Example: The cost of Landlord’s Work is $18,000 and the effective date of the termination notice is March 31, 2008. $18,000 ÷ 45 months = $400 × 15 months = $6,000 = the Unamortized
Portion.) Landlord estimates the cost of Landlord’s Work will be between $15,000 and $25,000 and represents that in no event shall the cost of Landlord’s Work exceed the sum of $25,000. Landlord shall provide Tenant with the actual cost of
Landlord’s Work upon its substantial completion. 
 (B) Notwithstanding Subparagraph (A) hereof, in the event that Tenant presents
to Landlord a replacement tenant (the “Replacement Tenant”) on or before the effective date of termination of this Lease, and Landlord (i) approves the Replacement Tenant and (ii) enters into a lease (the “Replacement
Lease”) with the Replacement Tenant for a term of at least twelve (12) months and the Replacement Tenant fully performs its obligations under the Replacement Lease for a minimum of twelve (12) months, Landlord shall refund a portion
of the Early Termination Fee to Tenant within thirty (30) days after the satisfaction of (B) (i) and (ii) above. The portion to be refunded shall be calculated by subtracting from the Early Termination Fee the sum of
(a) Base Rent and Operating Expenses for the period between the effective date of termination of this Lease and the date on which the Replacement Tenant begins to pay rent for the Leased Premises and (b) the cost of the fit-up which
Landlord must perform under the Replacement Lease.

covenants following, including Exhibit A attached hereto: 
 1st.
That the Tenant shall pay the annual rent of Sixty-Seven Thousand Eighty and 00/100 ($67,080.00) Dollars, said rent to be paid in equal monthly payments in advance on the 1st day of each and every month during the term aforesaid, as follows: Five Thousand Five Hundred Ninety and 00/100 ($5,590.00) Dollars per month commencing on
the first day of the first month and each and every month thereafter. Furthermore, if said rent is not received by the Landlord on or before the 10th day of the month, a 4% late charge will be added to rent and shall be paid with rent. 
 2nd. That the Tenant shall take good care of the Premises and shall, at the Tenant’s own cost and expense make all repairs except repairs to or replacement of heat, ventilation and air conditioning, plumbing,
structural, roof and mechanical systems (the “Landlord’s Items”) which are the responsibility of the Landlord, and at the end or other expiration of the term, shall deliver up the Demised Premises in good order or condition, damages
by the elements excepted. 
 3rd. That the Tenant shall promptly execute and comply with all the statutes, ordinances, rules,
orders, regulations and requirements of the Federal, State and Local Governments and of any and all their Departments and Bureaus applicable to said premises, for the correction, prevention, and abatement of nuisances or other grievances, in, upon
or connected with said premises during said term; and shall also promptly comply with and execute all rules, orders and regulations of the New York Board of Fire Underwriters, or any other similar body, at the Tenant’s own cost and expense; and
shall also promptly comply with and execute all rules of the Landlord imposed at the present or future time as may be necessary to ensure the safe use and occupancy of the Premises, or as may be necessary so as to not impair or waive any insurance
policy or coverage required herein or otherwise applicable to any portion of the Premises . Landlord warrants and represents (i) that on the Commencement Date, the Demised Premises will comply with all statutes, ordinances, rules, orders,
regulations and requirements of the Federal, State and Local Governments and of any and all their Departments and Bureaus applicable to the Demised Premises and (ii) that any Local Government approvals necessary for occupancy of the Demised
Premises by Tenant and the conduct of Tenant’s intended business therein have been obtained and are in full force and effect, except any approvals that are required because of the nature of the Tenant’s business (e.g., special use
permits). 
 4th. That the Tenant, successors, heirs, executors or administrators shall not make any alterations on the premises,
without the Landlord’s consent in writing, which consent shall not be unreasonably withheld; or occupy, or permit or suffer the same to be occupied for any business or purpose deemed disreputable or extra-hazardous on account of fire, under the
penalty of damages and forfeiture, and in the event of a breach thereof, the term herein shall immediately cease and determine at the option of the Landlord as if it were the expiration of the original term. 
 5th. Tenant must give Landlord prompt notice of fire, accident, damage or dangerous or defective condition. If the Premises can not be used
because of fire or other casualty, Tenant is not required to pay rent for the time the Premises are unusable. If part of the Premises can not be used, Tenant must pay rent for the usable part. Landlord shall have the right to decide which part of
the Premises is usable. Landlord need only repair the damaged structural parts of the premises. Landlord is not required to repair or replace any equipment, fixtures, furnishings or decorations 

 
unless originally installed by Landlord. Landlord is not responsible for delays due to settling insurance claims, obtaining estimates, labor and supply
problems or any other cause not fully under Landlord’s control

Tenant, tenant’s employees or invitees, or at the time of the fire or casualty Tenant is in default in any term of this Lease, then all repairs will be made at Tenant’s expense and Tenant must pay the full rent with no adjustment. The cost
of the repairs will be added rent. 
 Landlord has the right to demolish or rebuild the Building if there is substantial damage by
fire or other casualty. Landlord may cancel the lease within 30 days after the substantial fire or casualty by giving Tenant notice of Landlord’s intention to demolish or rebuild; if no notice is given, this Lease shall be deemed cancelled.
Tenant shall have the right to terminate the lease if 35% or greater of manufacturing/warehouse space of the Building has been rendered unusable, provided that Tenant gives Landlord notice of termination prior to the date, if any, on which Landlord
gives notice of Landlord’s intention to rebuild. This Lease will end 30 days after (a) Landlord’s cancellation notice to Tenant, (b) Tenant’s cancellation notice to Landlord, or (c) the date on which this Lease is
deemed cancelled. Tenant must deliver the Premises to landlord on or before the cancellation date in the notice and pay all rent due to the date of the fire or casualty .If the Lease is cancelled Landlord is not required to repair the Premises or
Building. The cancellation does not release Tenant of liability in connection with the fire or casualty. This section is intended to replace the terms of New York Real Property Law Section 227. If there is substantial damage by fire or other
casualty not caused by an act or neglect of Tenant, Tenant’s employees or invitees, Tenant may cancel this Lease if Landlord fails to rebuild the Building and deliver possession of the rebuilt Demised Premises within six (6) months after
the date of Landlord’s notice to intention to rebuild. 
 6th. The said Tenant agrees that the said Landlord and the
Landlord’s agent and other representatives shall have the right to enter into and upon said premises, or any part thereof, at all reasonable hours on reasonable notice if possible for the purpose of examining the same, or making such repairs or
alterations therein as may be necessary for the safety and preservation thereof.

Landlord or the Landlord’s agents to show the premises to persons wishing to hire or purchase the same at all reasonable hours on reasonable notice where possible; and the Tenant further agrees that on and after the sixth month, next preceding
the expiration of the term hereby granted, the Landlord or the Landlord’s agents shall have the right to place notices on the front of said premises, or any part thereof, offering the premises “To Let” or “For Sale”, and the
Tenant hereby agrees to permit the same to remain thereon without hindrance or molestation. 
 8th. That if the default be made
in the payment of the said rent or any part thereof, or if any default be made in the performance of any of the covenants herein contained, including but not limited to any anticipatory breach or default which Tenant fails to cure within ten
(10) days after written notice of such default, the Landlord or Landlord’s representatives may re-enter the said premises by force, summary proceedings or otherwise, and remove all persons therefrom, without being liable to prosecution
therefor, and the Tenant hereby expressly waives the service of any notice in writing of intention to re-enter, and the Tenant shall pay at the same time as the rent becomes payable under the terms hereof a sum equivalent to the rent reserved herein
and additional rent or other charges reserved herein, and the Landlord may rent the premises on behalf of the Tenant, reserving the right to rent the premises for a longer period of time than fixed in the original lease without releasing the
original Tenant from any liability, applying any moneys collected, first to the expense of resuming or obtaining possession, second to restoring the premises to a rentable condition, and then to the payment of the rent and all other charges due and
to become due to the Landlord, any surplus to be paid to the Tenant, who shall remain liable for any deficiency. Landlord shall also have the option of accelerating all sums, including rent, additional rent and other charges, becoming due under the
terms hereof after the date of such breach or default. If Landlord exercises such option, the Present Value (hereinafter defined) of all such sums shall become immediately due and payable as of the date on which Landlord notifies Tenant of
Landlord’s exercises of its option to accelerate as hereinabove provided, together with all sums past due. As used herein, the term “Present Value” means the present value of all sums 

 
due under the terms hereof after the date of Tenant’s breach or default, discounted at the rate of eight (8%) percent per annum.

the carelessness, negligence or improper conduct on the part of the said Tenant or the Tenant’s agents or employees. Damage and injury to the Premises or the common areas of the building on which the Premises is located, including the
Landlord’s items, caused by the carelessness, negligence or improper conduct on the part of the said Tenant or the Tenant’s agents or employees shall be repaired as speedily as possible by the Tenant at the Tenant’s own cost and
expense, or if Tenant fails to do so, by the Landlord at the expense of Tenant.

nor obstruct the sidewalk in front of, entrance to, or halls and stairs of said premises, nor allow the same to be obstructed or encumbered in any manner.

places as may be indicated by the Landlord and consented to by the Landlord in writing. And in case the Landlord or the Landlord’s representatives shall deem it necessary to remove any such sign or signs in order to paint the said premises or
the building wherein same is situated or make any other repairs, alterations or improvements in or upon said premises or building or any part thereof, the Landlord shall have the right to do so, providing the same be removed and replaced at the
Landlord’s expense, whenever the said repairs, alterations or improvements shall be completed. Landlord shall provide directory signs for the tenants in the building in the first floor and second floor lobbies. The cost of manufacture of
Tenant’s signs in the above referenced directory signs, and any replacement thereof, shall be borne by Tenant.

 13th. Intentionally Deleted. 
 14th. That this instrument shall not be a lien against said premises in respect to any mortgages that are now on or that hereafter may be placed against said premises, and that the recording of
such mortgage or mortgages shall have preference and precedence and be superior and prior in lien of this lease, irrespective of the date of recording and the Tenant agrees to execute without cost, any such instrument which may be deemed necessary
or desirable to further effect the subordination of this lease to any such mortgage or mortgages, in the event Tenant fails to execute any such instrument, Tenant hereby authorizes Landlord to execute any such instrument with the same force as
effect as if executed by Tenant. In the alternative, Landlord shall have the option of canceling this Lease without incurring any expense or damage and the term hereby granted shall be expressly limited accordingly. Notwithstanding the foregoing,
Landlord shall provide a subordination, non-disturbance and attornment agreement (“SNDA”) in the form used by Landlord’s mortgage holder which Tenant shall execute and Landlord shall cause to be executed by the mortgage lender.

Dollars as security for the full and faithful performance by the Tenant of all the terms, covenants and conditions of this lease upon the Tenant’s part to be performed, which said sum shall be returned to the Tenant after the time fixed as the
expiration of the term herein, provided the Tenant has fully and faithfully carried out all of said terms, covenants and conditions on Tenant’s part to be performed. In the event of a bona fide sale, subject to this lease, the Landlord shall
have the right to transfer the security to the vendee for the benefit of the Tenant and the Landlord shall be considered released by the Tenant from all liability for the return of such security; and the Tenant agrees to look to the new Landlord
solely for the return of the said security, and it is agreed that this shall apply to every transfer or assignment made of the security to a new Landlord. 
 16th. That Tenant shall not mortgage or otherwise encumber Tenant’s leasehold
interest in the Premises or the security deposited under this Lease, and shall not assign the security except in connection with an assignment to which Landlord consents pursuant to Paragraph 4th hereof. 

 17th. It is expressly understood and agreed that if the Tenant shall file or there be filed
against Tenant a petition in bankruptcy or arrangement, or Tenant be adjudicated a bankrupt or make an assignment for the benefit of creditors or take advantage of any insolvency act, the Landlord may, if the Landlord so elects, at any time
thereafter terminate this lease and the term hereof, on giving to the Tenant five days’ notice in writing of the Landlord’s intention so to do, and this lease and the term hereof shall expire and come to an end on the date fixed in such
notice as if the said date were the date originally fixed in this lease for the expiration hereof. Such notice may be given by mail to the Tenant addressed to the demised premises. 
 18th. That the Tenant will not nor will the Tenant permit undertenants or other persons to do anything in said premises, or bring anything into said premises, or permit anything to be brought
into said premises or to be kept therein, which will in any way increase the rate of fire insurance on said demised premises, nor use the demised premises or any part thereof, nor suffer or permit their use for any business or purpose which would
cause an increase in the rate of fire insurance on said building, and the Tenant agrees to pay on demand any such increase. 
 19th. The failure of the Landlord to insist upon a strict performance of any of the terms, conditions and covenants herein, shall not be deemed a waiver of any rights or remedies that the Landlord may have, and shall
not be deemed a waiver of any subsequent breach or default in the terms, conditions and covenants herein contained. The failure of the Tenant to insist upon a strict performance of any of the terms, conditions and covenants herein, shall not be
deemed a wavier of any rights or remedies that the Tenant may have, and shall not be deemed a waiver of any subsequent breach or default in the terms, conditions and covenants herein contained. This instrument may not be changed, modified,
discharged or terminated orally. 
 20th. 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 against Landlord for the value of
any unexpired term of said lease. No part of any award shall belong to the Tenant. 
 21st. If after default in payment of rent
or violation of any other provision of this lease, or upon the expiration of this lease, the Tenant moves out or is dispossessed and fails to remove any trade fixtures or other property prior to such said default, removal, expiration of lease, or
prior to the issuance of the final order or execution of the warrant, then and in that event, the said fixtures and property shall be deemed abandoned by the said Tenant and shall become the property of the Landlord. 
 22nd. It is mutually agreed between Landlord and Tenant that the respective parties hereto shall and hereby do waive trial by jury in any action,
proceeding or counterclaim brought by either of the parties against the other on any matters whatsoever arising out of or in any way connected with this lease, the Tenant’s use or occupancy of said premises, and/or any claim of injury or
damage. 
 23rd. The Tenant waives all rights to redeem under any law of the State of New York. 
 24th. 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 nowise be affected, impaired or excused because Landlord is unable to supply or is delayed in supplying any service expressly or impliedly to be supplied or is unable to make, or is delayed in making any repairs,
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 governmental preemption in connection with a National Emergency or in
connection with any rule, order or regulation of any department or subdivision thereof of any governmental agency or by reason of the condition of supply and demand which have been or are affected by war or other emergency. 
 25th. No diminution or abatement of rent, or other compensation, shall be claimed or allowed for inconvenience or discomfort arising from the
making of repairs or improvements to the building or to its appliances, nor for any space taken to comply with any law, ordinance or order of a governmental authority. In respect to the various “services,” if any, herein expressly or
impliedly agreed to be furnished by the Landlord to the Tenant, it is agreed that there shall be no diminution or abatement of the rent, or any other compensation, for interruption or curtailment of such 

 
“service” when such interruption or curtailment shall be due to accident, alterations or repairs desirable or necessary to be made or to
inability or difficulty in securing supplies or labor for the maintenance of such “service” or to some other cause, not negligence on the part of the Landlord. No such interruption or curtailment of any such “service” shall be
deemed a constructive eviction. The Landlord shall not be required to furnish, and the Tenant shall not be entitled to receive, any of such “services” during any period wherein the Tenant shall be in default in respect to the payment of
rent. Neither shall there be any abatement or diminution of rent because of making of repairs, improvements or decorations to the demised premises after the date above fixed for the commencement of the term, it being understood that rent shall, in
any event, commence to run at such date so above fixed. 
 26th. Landlord shall not be liable for failure to give possession of
the premises upon commencement date by reason of the fact that premises are not ready for occupancy or because a prior Tenant or any other person is wrongfully holding over or is in wrongful possession, or for any other reason. The rent shall not
commence until possession is given or is available, but the term herein shall not be extended. 
 And the said Landlord doth covenant
that the said Tenant on paying the said yearly rent, and performing the covenants aforesaid, shall and may peacefully and quietly have, hold and enjoy the said demised premises for the term aforesaid, provided however, that this covenant shall be
conditioned upon the retention of title to the premises by the Landlord. 
 And it is mutually understood and agreed that the
covenants and agreements contained in the within lease shall be binding upon the parties hereto and upon their respective successors, heirs, executors and administrators. 

 In Witness Whereof, the parties have interchangeably set their hands and seals (or caused these presents to be signed
by their proper corporate officers and caused their proper corporate seal to be hereto affixed) this 6 day of April, 2006.
