proportionate share and/or the taxes attributable to the Tenant’s leasehold improvements and add the amount so paid to the next month’s rent accruing hereunder. Landlord shall have the right to collect the same from Tenant as additional
rent and Landlord shall have the same remedy for the non-payment hereof as for the non-payment of rent as herein provided.

and permit the Tenant (it keeping all of the covenants on its part as herein contained) to occupy, possess and quietly enjoy said premises during the term hereof, without hindrance from Landlord or any person claiming by, from or under it, subject,
nevertheless, to the terms of this Lease and any mortgage, ground lease or agreements to which this Lease is subordinated. 
  
 7. Tenant’s Covenants. The Tenant covenants with the Landlord to hire said leased premises and to pay rent and all other
charges and payments to be made herein, and to keep all of its covenants as contained herein, that it will commit no waste, nor suffer the same to be committed thereon. Tenant shall promptly comply with all present and future laws, orders and
regulations of all state, federal, municipal and local governments, departments, commissions and boards and any direction of any public officers pursuant to law. Notwithstanding any provision to the contrary herein, Tenant shall not be liable to
Landlord for any violation of any environmental law or regulation that is determined to have been caused directly or indirectly by any person or entity other than Tenant and its employees, agents, contractors, licensees, successors and assigns.

  
 8. No Representations. The Tenant
accepts the building improvements and personalty on the leased premises in their present state and without any representation or warranty by the Landlord or its agents as to the condition of such property or as to the use which may be made thereof.

change of the condition thereof, any damage occurring thereto or the existence with respect thereto of any violations of the laws or regulations of any governmental authority. 
  
 9. Alterations. Tenant shall make no changes in or to the leased premises of any nature without
Landlord’s prior written consent, which consent shall not unreasonably be withheld or delayed. Notwithstanding the foregoing sentence, Tenant may make alterations or improvements to the leased premises which do not exceed the sum of $5,000.00
in cost (materials and labor), so long as such alterations and improvements are interior and non-structural, and are commensurate and compatible with the architecture, design, style and of the same quality of material and construction, as the other
portions of the leased premises and the Building. Tenant shall provide Landlord, upon its request, final and complete drawings and specifications as may be necessary to obtain required building permits for all work to be done in connection with any
build-out of the leased premises and any alterations made by the Tenant. Landlord shall approve or disapprove Tenant’s plans within a reasonable time thereafter. In the event Landlord disapproves Tenant’s plans, Landlord shall set forth
the reasons therefor. Any revised plans shall correct any deficiencies and conform to any objections set forth by Landlord. It is specifically agreed herein that, in the event that any utility services, facilities, equipment, electrical lines or
duct-work need to be altered in any respect in the 

  

 -3- 








 
course of Tenant’s build-out of or changes or alterations to, the Demised Premises, all costs and expenses of the same shall be paid by Tenant.

  
 Upon receipt of Landlord’s written consent, Tenant, at
Tenant’s expense, may make alterations, installations, additions or improvements which are non-structural and which do not affect utility services or plumbing and electrical lines, in or to the interior of the leased premises by using
contractors and mechanics first approved by Landlord. Tenant shall, before making any alterations, additions, installations or improvements, at its expense, obtain all permits, approvals and certificates required by any governmental or
quasi-governmental bodies and (upon completion) certificates of final approval thereof and shall deliver promptly duplicates of all such permits, approvals and certificates to Landlord. Tenant agrees to carry and will cause Tenant’s contractors
and sub-contractors to carry such workman’s compensation, general liability, personal and property damage insurance as Landlord may require. If any mechanic’s lien is filed against the leased premises or the Building for work claimed to
have been done for, or materials furnished to, Tenant, the same shall be discharged by Tenant within thirty (30) days thereafter, at Tenant’s expense, or by the filing of a bond required by law. Unless otherwise agreed by Landlord in
writing prior to installation, all fixtures, paneling, partitions and like installations, installed in the leased premises at any time, either by Tenant or by Landlord in Tenant’s behalf, shall, upon installation become the property of Landlord
and shall remain upon and be surrendered with the leased premises unless Landlord, by notice to Tenant no later than sixty (60) days prior to the date fixed as the termination of this Lease, elects to relinquish Landlord’s right thereto
and to have them removed by Tenant, in which event the same shall be removed from the premises by Tenant prior to the expiration of the Lease, at Tenant’s expense. All property permitted or required to be removed by Tenant at the end of the
term remaining in the leased premises after Tenant’s removal, shall be deemed abandoned and may, at the election of Landlord, either be retained as Landlord’s property or may be removed from the premises by Landlord at Tenant’s
expense. 
  
 Notwithstanding any provision or term of this Lease
to the contrary, Tenant acknowledges Landlord’s concerns regarding the conversion of laboratory space in the building to office space. In the event Landlord consents in writing to the conversion of laboratory space to office space, all utility
and mechanical systems, including but not limited to plumbing, electricity, HVAC, phone, data, security, alarm and sprinkler, that require modification or capping, shall be completed in accordance with a plan approved by Landlord in writing prior to
the work being performed which plan shall allow for the space to be easily converted back to laboratory space. Existing tile flooring, if covered, shall be covered in a manner, approved by Landlord in writing prior to the work, that provides for the
removal of the covering without damage, stain, discoloration, residue, or alteration of the existing tile floors. 
  
 10. Damage, Injury. Insurance. (a) Tenant shall indemnify and save harmless Landlord from and against any and all liability,
damage, penalties or judgments arising from injury to person or property sustained by anyone in and about the leased premises resulting from any act or acts or omission or omissions of Tenant, or Tenant’s officers, agents, servants, employees,
contractors, or sublessees. Tenant shall, at its own cost and expense, defend any and all suits or actions (just or unjust) which may be brought against Landlord or in which Landlord may be impleaded with others upon any such above-mentioned matter,
claim or claims. 
  
 (b) The Landlord shall not
be liable for any damage or injury to the leased premises, or to any property of the Tenant of any other person thereon, from water, rain, snow, ice, sewerage, steam, gas or electricity which may leak into or issue or flow from any part of the
Building of which the leased premises are a part, or from the bursting, breaking, obstruction, leaking or any defect of any of the pipes or plumbing, appliances or from electric wiring or other fixtures in the Building, or from the condition of the
premises or Building or any part thereof, from the street or subsurface, unless caused by Landlord’s negligence or willful neglect. 
  

 -4- 








 (c) Tenant shall provide at its expense, and keep in force during the term of this lease,
general liability insurance in a good and solvent insurance company or companies licensed to do business in the State of Connecticut, selected by Tenant, and reasonably satisfactory to the Landlord, in the amount of at least One Million
($1,000,000.00) Dollars combined single limit in respect to any one occurrence with respect to injury or death to any one or more than one person and One Million ($1,000,000.00) Dollars with respect to damages to property. Such policy or policies
shall include Landlord and any mortgagee named by Landlord as assureds. Tenant agrees to deliver certificates of such insurance to Landlord prior to the beginning of the term of this Lease and thereafter not less than ten (10) days prior to the
expiration of any such policy. Such insurance shall be noncancellable without ten (10) days’ written notice to Landlord, and to each such mortgagee. 
  

(d) If by reason of any act or omission or negligence on the part of Tenant or any employee or agent of Tenant, whether or not Landlord
has consented to the same, the rate of fire or other property insurance of Landlord or of any other Tenant in the Building shall be higher than it otherwise would be, Tenant shall reimburse Landlord, and all such other Tenants, on demand, for that
part of the premiums for such insurance paid by Landlord or such other Tenants, because of such act or omission or negligence on the part of Tenant or any employee or agent of Tenant. Tenant shall also pay any increase in premiums on any rent
insurance carried by Landlord for its protection against rent loss and fire or other casualty if such increase shall result from any of the foregoing events. 
  

(e) All insurance policies carried by Tenant covering the leased premises, as required herein, shall expressly waive any right on the
part of the insurer or the insured against the Landlord, except as otherwise specifically provided herein. 
  
 11. Assignment and Subletting. Tenant, for itself, its successors and assigns, expressly covenants that it shall not assign,
mortgage or encumber this Lease, nor sublet, or suffer or permit the leased premises or any part thereof to be used by others, without the prior written consent of Landlord in each instance. Any merger or consolidation of Tenant or the transfer of
more than fifty (50%) percent of the stock of Tenant shall be deemed an assignment. Notwithstanding the foregoing sentence, any trading of Tenant’s stock on a nationally-recognized security exchange will not be deemed an assignment. If
this Lease be assigned, or if the leased premises or any part thereof be sublet or occupied by anyone other than Tenant, Landlord may, after default by Tenant, collect from the assignee, subtenant or occupant, and apply the net amount collected to
the rent herein reserved, but no such assignment, subletting, occupancy or collection shall be deemed a waiver of this covenant, or the acceptance of the assignee, subtenant or occupant as Tenant, or a release of Tenant from the further performance
by Tenant of covenants on the part of Tenant herein contained. Notwithstanding the foregoing, Tenant shall be permitted to sublet the leased premises provided that: 
  

	 	(i)	Tenant submits to Landlord the name and address of the proposed subtenant; 

  

	 	(ii)	Tenant delivers to Landlord a term sheet containing the material business terms of the proposed sublease and a copy of any sublease which is executed; 

  

	 	(iii)	The character of the proposed subtenant is reasonably satisfactory to Landlord and shall not in Landlord’s opinion, adversely affect the Building or Landlord’s financial
interest therein; 

  

	 	(iv)	Tenant delivers to Landlord banking, financial and other credit information relating to the proposed subtenant and such information is reasonably satisfactory to Landlord; and


  

	 	(v)	The sublease expressly provides that it is subject and subordinate to this Lease. 

  

 -5- 








 The consent by Landlord to any assignment or subletting shall not constitute a waiver of the necessity
for such consent to any subsequent assignment or subletting. This prohibition against assigning or subletting shall be construed to include a prohibition against any assignment or subletting by operation of law. Notwithstanding any provision to the
contrary in this paragraph 12, Landlord shall not unreasonably withhold or delay its consent to any assignment of this Lease provided that the conditions set forth in this paragraph 12 have been satisfied. Any rentals and other consideration paid or
payable to Tenant by any subtenant or assignee in excess of the rentals and other payments due under this Lease from Tenant to Landlord shall be paid by Tenant as and when received by Tenant to Landlord in addition to the rental and other payments
otherwise due hereunder. 
  
 12.
Condemnation. It is expressly agreed that if the entire leased premises shall be taken by public or quasi-public authority under the power of eminent domain or condemnation, this Lease shall terminate on the date of such taking and the rights
of the Tenant shall forthwith cease, with rent to be apportioned as of the date of such taking. No part of any award for such taking shall belong to Tenant. If any part of the leased premises shall be taken as aforesaid, and such partial taking
shall render that portion not so taken unsuitable for the business of Tenant, then this Lease and the term herein shall cease and terminate as aforesaid. If such partial taking is not extensive enough to render the leased premises unsuitable for the
business of Tenant, then this Lease shall continue in effect except that the rent shall be reduced in the same proportion that the floor area of the leased premises taken bears to the original floor area demised and Landlord shall, upon receipt of
the award in condemnation, make all necessary repair or alterations to the Building in which the leased premises are located, but such work shall not exceed the scope of the work done in the original construction of said Building, nor shall Landlord
in any event be required to spend for such work an amount in excess of the amount received by the Landlord as damages for part of the leased premises so taken. “Amount received by the Landlord” shall mean that part of the award in
condemnation which is free and clear to Landlord of any collection by mortgagees for the value of the diminished fee. Notwithstanding the foregoing, if more than twenty (20%) percent of the floor area of the Building shall be taken as
aforesaid, Landlord may, by written notice to Tenant, terminate this Lease, such termination to be effective as aforesaid. If this Lease is terminated as provided in this paragraph, the rent shall be paid up to the day that possession is so taken by
public authority and Landlord shall make an equitable refund of any rent paid by Tenant in advance. In no event shall Tenant be entitled to, and Tenant expressly waives hereby, all claims to any condemnation award for any taking, whether whole or
partial, and whether for diminution in value of the leasehold or to the fee although, Tenant shall have the right, to claim from the condemnor, but not from Landlord, such compensation as may be recoverable by Tenant in its own right for damage to
Tenant’s business, relocation costs and fixtures. 
  
 13. Maintenance. Tenant shall, throughout the term of this Lease, take good care of the leased premises and the fixtures and appurtenances therein. Tenant shall be responsible for all damage or injury to the Demised Premises or any
other part of the Demised Premises and Warehouse and the systems and equipment thereof, whether requiring structural or non-structural repairs caused by or resulting from carelessness, omission, neglect or improper conduct of Tenant, Tenant’s
subtenants, agents, employees, invitees or licensees, or which arise out of any work, labor, service or equipment done for or supplied to Tenant or any subtenant or arising out of the installation, use or operation of the property or equipment of
Tenant or any subtenant. Tenant shall also repair all damage to the Demised Premises caused by the moving of Tenant’s fixtures, furniture and equipment. Landlord shall maintain in good working order and repair the exterior and the structural
portions of the Demised Premises as well as the public portions of the Building interior and the Building plumbing and electrical systems located outside of but serving the leased premises. Landlord shall maintain in good working order and repair
the heating, air-conditioning and ventilating systems located within the Demised Premises. All of Landlord’s expenses incurred in the maintenance of the Demised Premises shall be considered operating expenses payable by Tenant as additional
rent in accordance with Section 5 of this Lease. Tenant shall maintain in good working order and repair those portions of utility systems, including but not limited to, plumbing, electrical and lighting systems (including the purchase and
replacement of light bulbs), located within the 

  

 -6- 








 
Demised Premises. Tenant agrees to give prompt notice of any defective condition in the Demised Premises for which Landlord may be responsible hereunder.
There shall be no allowance to Tenant for diminution of rental value and no liability on the part of Landlord by reason of inconvenience, annoyance or injury to business arising from Landlord or others making repairs, alterations, additions or
improvements in or to any portion of the Demised Premises or in and to the fixtures, appurtenances or equipment thereof, provided Landlord is prosecuting such repairs, alterations, additions or improvements with reasonable diligence. It is
specifically agreed that Tenant shall not be entitled to any set off or reduction of rent by reason of any failure of Landlord to comply with the covenants of this or any other article of this Lease. Tenant agrees that Tenant’s sole remedy at
law in such instance will be by way of an action for damages for breach of contract. Upon the expiration or other termination of the term of this Lease, Tenant shall quit and surrender to Landlord the Demised Premises, broom-clean, and in good order
and condition, ordinary wear excepted, and Tenant shall remove all of its property. 
  
 14. Destruction. (a) If the leased premises or any part thereof shall be damaged by fire or other casualty, Tenant shall give
immediate notice thereof to Landlord and this Lease shall continue in full force and effect except as hereinafter set forth. (b) If the leased premises are partially damaged or rendered partially unusable by fire or other casualty, the damages
thereto shall be repaired by and at the expense of Landlord and the rent, until such repair shall be substantially completed, shall be apportioned from the day following the casualty according to the part of the premises which is usable. (c) If
the leased premises are totally damaged or rendered wholly unusable by fire or other casualty, then the rent shall be proportionately paid up to the time of the casualty and thenceforth shall cease until the date when the premises shall have been
repaired and restored by Landlord, subject to Landlord’s right to elect not to restore the same as hereinafter provided. (d) If the leased premises are rendered wholly unusable or (whether or not the leased premises are damaged in whole or
in part) if the building shall be so damaged that Landlord shall decide to demolish it or to rebuild it, then, in any of such events, Landlord may elect to terminate this lease by written notice to Tenant, given within ninety (90) days after
such fire or casualty, specifying a date for the expiration of the lease, which date shall not be more than sixty (60) days after the giving of such notice, and upon the date specified in such notice the term of this Lease shall expire as fully
and completely as if such date were the date set forth above for the termination of this Lease and Tenant shall forthwith quit, surrender and vacate the premises without prejudice however, to Landlord’s rights and remedies against Tenant under
the Lease provisions in effect prior to such termination, and any rent owing shall be paid up to such date and any payments of rent made by Tenant which were on account of any period subsequent to such date shall be returned to Tenant. Unless
Landlord shall serve a termination notice as provided for herein, Landlord shall make the repairs and restorations under the conditions of (b) and (c) hereof, with all reasonable expedition, subject to delays due to adjustment of insurance
claims, labor troubles and causes beyond Landlord’s control. After any such casualty, Tenant shall cooperate with Landlord’s restoration by removing from the premises as promptly as reasonably possible, all of Tenant’s salvageable
inventory and movable equipment, furniture, and other property. Tenant’s liability of rent shall resume five (5) days after written notice from Landlord that the premises are substantially ready for Tenant’s occupancy.
(e) Nothing contained hereinabove shall relieve Tenant from liability that may exist as a result of damage from fire or other casualty. Notwithstanding the foregoing, each party shall look first to any insurance in its favor before making any
claim against the other party for recovery for loss or damage resulting from fire or other casualty, and to the extent that such insurance is in force and collectible and to the extent permitted by law, Landlord and Tenant each hereby releases and
waives all right of recovery against the other or any one claiming through or under each of them by way of subrogation or otherwise. The foregoing release and waiver shall be in force only if both releasors’ insurance policies contain a clause
providing that such a release or waiver shall not invalidate the insurance. If, and to the extent, that such waiver can be obtained only by the payment of additional premiums, then the party benefiting from the waiver shall pay such premium within
ten (10) days after written demand or shall be deemed to have agreed that the party obtaining insurance coverage shall be free of any further obligation under the provisions hereof with respect to waiver of subrogation. Tenant acknowledges that
Landlord will not carry insurance on Tenant’s furniture 

  

 -7- 








 
and/or furnishings or any fixtures or equipment, improvements, or appurtenances removable by Tenant and agrees that Landlord will not be obligated to repair
and damage thereto or replace the same. 
  
 15.
Subordination and Non-Disturbance. This Lease is subject and subordinate to all ground or underlying leases and to all mortgages which may now or hereafter affect such leases or the real property of which the leased premises are a part,
provided that the holder thereof agrees to recognize Tenant’s rights under this Lease and not to disturb Tenant’s possession of the leased premises as long as Tenant is not in default of its obligations under this Lease. This clause shall
be self-operative and no further instrument shall be required by any ground or underlying lessor or by any mortgagee affecting any lease or the real property of which the leased premises are a part. In confirmation of such subordination, Tenant
shall execute promptly any certificate that Landlord may request in writing. 
  
 16. Attornment. Tenant shall in the event of the sale or assignment of the Landlord’s interest in the Building, or in the event of any proceedings brought for the foreclosure of, or in the event of
exercise of the power of sale under any mortgage made by Landlord covering the Building, attorn to the purchaser and recognize such purchaser as Landlord under this Lease, provided the purchaser agrees to recognize Tenant’s rights under this
Lease and not to disturb Tenant’s possession of the leased premises as long as Tenant is not in default of its obligations under this Lease. 
  
 17. Use of Premises. Tenant shall use and occupy the leased premises as a biopharmaceutical research laboratory and offices, and
for no other purpose. Tenant shall not bring any animal onto or within the leased premises for research or other purposes. 
  
 18. Signs. The Tenant further covenants and agrees with the Landlord not to place, or permit to be placed, any signs, advertising
display material, antennas or mechanical devices or any other items on the exterior of the building, sidewalk, common areas or property adjoining said leased premises in which said leased premises are located, except as permitted in writing by the
Landlord, or as currently maintained thereon. 
  
 19. Default; Remedies. 
  
 A. If
Tenant defaults in fulfilling any of the covenants of this Lease, other than the covenants for the payment of rent, or in making any other payment herein provided, or if the leased premises become vacant or deserted, or if the leased premises are

said default, and upon the expiration of said ten (10) business days, if Tenant shall have failed to comply with or remedy such default, or if the said default or omission complained of shall be of such a nature that the same cannot be
completely cured or remedied within said ten (10) business day period, and if Tenant shall not have diligently commenced curing such default within such ten (10) business day period, and shall not thereafter with reasonable diligence and
in good faith proceed to remedy or cure such default, Landlord may serve a written three (3) day notice of cancellation of this Lease upon Tenant, and upon the expiration of said three (3) days, this Lease and the term hereunder shall end
and expire as fully and completely as if the date of expiration of such three (3) day period were the date herein definitely fixed for the end and expiration of this Lease and the term thereof, and Tenant shall then quit and surrender the
leased premises to Landlord, but Tenant shall remain liable as hereinafter provided. 
  
 B. If the notice provided for in paragraph A hereof shall have been given, and the term shall expire as aforesaid; or (1) if Tenant

extension of this Lease, Landlord may cancel and terminate such renewal or extension agreement by written notice, but Tenant shall remain liable as hereinafter provided. 
  
 C. In the case of any such default, re-entry, expiration, and/or dispossess by summary proceedings or
otherwise, (a) the fixed rent and all other payments shall become due thereupon and be paid to the time of such re-entry, dispossess, and/or expiration, together with such expenses as Landlord may incur for legal expenses, attorney’s fees,
brokerage, and/or putting the leased premises in good order, or for preparing the same for re-rental; (b) Landlord may relet the leased premises or any part or parts thereof, either in the name of Landlord or otherwise, for a term or terms,
which may, at Landlord’s option, be less than or exceed the period which would otherwise have constituted the balance of the term of this Lease, and may grant concessions or free rent; and\or (c) Tenant or the legal representative of
Tenant shall also pay Landlord as liquidated damages for the failure of Tenant to observe and perform said Tenant’s covenants herein contained, any deficiency between rent and additional rents hereby reserved and/or covenants to be paid and the
net amount, if any, of the rents collected or to be collected on account of the lease or leases of the leased premises for each month of the period which would otherwise have constituted the balance of the term of this Lease. Landlord shall use
commercially reasonable efforts to relet the leased premises; provided, however, the failure of Landlord to relet the leased premises or any part or parts thereof shall not release or affect Tenant’s liability for damages. In computing such
damages, there shall be added to the said deficiency such expenses as Landlord may incur in connection with reletting, such as legal expenses, attorneys’ fees, brokerage, and expenses for keeping the leased premises in good order or for
preparing the same for reletting. Any such damages shall be paid in monthly installments by Tenant on the rent days specified in this Lease, and any suit brought to collect the amount of the deficiency for any month or months shall not prejudice in
any way the right of Landlord to collect the deficiency for any subsequent month or months by a similar proceeding. In lieu thereof, Landlord may immediately accelerate such deficiency for the entire balance of the term. Landlord at Landlord’s
option, may make such alterations, repairs, replacements, and/or decorations in the leased premises as Landlord in Landlord’s sole judgment considers advisable and necessary for the purpose of reletting the leased premises; and the making of
such alterations and/or decorations shall not operate or be construed to release Tenant from liability hereunder as aforesaid. Landlord shall in no event be liable in any way whatsoever for failure to relet the leased premises, or in the event that
the leased premises are relet, for failure to collect the rent thereof under such reletting. Any such action may be an action for the full amount of all rents and damages suffered or to be suffered by Landlord. In the event of a breach or threatened
breach by Tenant of any of the covenants or provisions hereof, Landlord shall have the right of injunction and the right to invoke any remedy allowed at law or in equity as if re-entry, summary proceedings, and other remedies were not herein
provided for. Mention in this Lease of any particular remedy shall not preclude Landlord from any other remedy in law or in equity. The foregoing remedies and rights of Landlord are cumulative. Tenant hereby expressly waives any and all rights of
redemption granted by or under any present or future laws in the event of Tenant’s being evicted or dispossessed for any cause, or in the event of Landlord’s obtaining possession of the leased premises by reason of the violation by Tenant
of the covenants and conditions of this Lease, or otherwise.

required to employ an attorney in order to enforce any provision of this Lease, the Tenant shall pay reasonable attorneys’ fees and all other costs of collection. 
  
 21. Security, Cleaning, Maintenance and Refuse. Subject to the provisions of Section 5.
Additional Rent of this Lease, the Landlord will provide all exterior maintenance, including, but not limited to, the cutting of the grass and maintenance of other landscaping, snow plowing, and removal of snow from adjacent sidewalks. Tenant
at its expense shall provide cleaning service and maintenance of the Demised Premises including all halls and lavatories and exterior stairways. Tenant shall, at its own expense, keep and maintain refuse dumpsters of a kind approved or specified by
Landlord, in the area specified by Landlord, and prepare same for collection in the manner and at the times specified by Landlord. 
  
 Tenant, at its sole cost and expense shall provide such security system as it desires in its sole discretion, subject however to the
provisions of Section 9. Alterations of this Lease, and, at its sole cost and expense, Tenant shall provide Landlord and the occupant of the space currently occupied by Canavan Corporation, access to the security codes, access cards,
etc. to allow access to the Building and the Canavan Corporation space. 
  
 22. No Recording. Notice of Lease. Tenant covenants that in the event this Lease is recorded upon the Land Records of the Town of Branford by Tenant, it shall become null and void at the option of the Landlord.
The parties agree to execute and Tenant agrees to record, at its sole cost and expense, a Notice of Lease setting forth the terms of this Lease. 
  
 23. Utilities. Tenant agrees to make its own arrangements with the public utility company servicing the leased premises for the
furnishing of electricity, telephone and other utilities excluding natural gas and water service used or consumed in the Building and Warehouse and for the installation of meters therefore. Landlord shall not be responsible for charges for
electricity, telephone or any other utilities used or consumed in the Building and Warehouse, all of which charges shall promptly be paid by Tenant, when due, to the applicable utility or vendor. All meters at the leased premises for the purposes of
measuring Tenant’s consumption of the respective utility shall be maintained by Tenant, at Tenant’s sole cost and expense, in good order and condition. Landlord shall not be liable in any way to Tenant for any failure or defect in the
supply or character of gas, electric energy, or other utility furnished to the Demised Premises. Interruption or curtailment of such services shall not constitute a constructive or partial eviction nor entitle Tenant to any compensation or abatement
of rent. All utility expenses, including but not limited to gas, water and electricity metered and billed to the Landlord’s account shall be considered operating expenses and payable by Tenant as additional rent in accordance with
Section 5 of this Lease. At its option, Tenant may, at its own cost and expense, make the necessary connections into Landlord’s generator in order to provide for service to the Demised Premises, provided, however, that such
generator has the requisite capacity to provide such service, and further, provided that Tenant indemnifies Landlord for any damages to such generator and any loss of use resulting from Tenant’s efforts to connect to, and
Tenant’s use of, such generator. Tenant shall give Landlord prior notice of its determination to use the generator and inform Landlord of the date(s) of anticipated connection thereto. Tenant shall continue semi-annual servicing of the
generator and shall be responsible for all costs therefor and for fueling and operation of such generator, and Tenant shall provide Landlord with copies of all maintenance and service records and billing statements within fifteen (15) days of
Tenant’s receipt of those records and billing statements. 
  
 24. Notice. Any and all notices, acceptances or any other communication provided for herein shall be given in writing by registered or certified mail which shall be addressed as set forth below. Each such
notice shall be deemed given at the time it is mailed in any post office or branch post office regularly maintained by the United States Government.

Tenant’s remedies under or with respect to this Lease, the relationship of Landlord and Tenant hereunder or Tenant’s use or occupancy of the leased premises. The limitation on Tenant’s right to look only to Landlord’s estate


  

 -11- 








 
and property in the Building for satisfaction of remedies for the collection of a judgment (or other judicial process) requiring the payment of money by
Tenant in the event of any default by Landlord hereunder shall not limit in any way Tenant’s right to specifically enforce any provision of this Lease. 
  
 29. Licenses and Permits. Tenant will apply for, comply with and maintain all licenses and permits necessary of the operation of
Tenants’s business in the leased premises, including any environmental, health and safety permits required because of the nature of Tenant’s business.

installations or interfere with the use thereof by other Tenants of the Building; (c) use the leased premises in a manner that causes or in Landlord’s reasonable opinion would likely cause physical damage to the Building, or any part
thereof; (d) use the leased premises in a manner that impairs or unreasonably interferes with any Building services or any machinery or equipment used in connection with operating and maintaining the Building or unreasonably interferes with,
annoys or inconveniences Landlord or other Tenants of the Building.

shall be payable on such sum or so much thereof as shall be unpaid from the date it first became due until it is paid. Such interest shall be at an annual rate (the “Interest Rate”) which shall be two (2) percentage points higher than
the Prime Lending Rate (as hereinafter defined), but in no event more than the highest rate of interest which at such time shall be permitted under the laws of the State of Connecticut. The term, “Prime Lending Rate” shall mean the rate
announced from time to time by Citibank, N.A., its successors and assigns, at its main office in New York, New York as its prime rate; or if such bank shall not exist, the rate announced by such other commercial bank in New York City as shall be
designated by Landlord as its prime rate. 
  
 32.

for all costs of materials and labor incurred in connection with any such upgrade, alteration or improvement undertaken. 
  
 34. Remedies Cumulative. All rights and remedies of Landlord herein created or remedies otherwise existing at law or equity are
cumulative and the exercise of one or more rights or remedies shall not be taken to exclude or waive the right to be exercised of any other. All such rights and remedies may be exercised and enforced concurrently and whenever and as often as
Landlord deems desirable. The failure of Landlord to insist upon strict performance by Tenant of any of the covenants, conditions and agreements of this Lease shall not be deemed a waiver of any of Landlord’s rights or remedies and shall not be
deemed a waiver of any of said rights or remedies concerning any subsequent or continuing breach or default by Tenant of any of the covenants, conditions and agreements of this Lease. No surrender of the leased premises shall be effected by

Landlord’s acceptance of rental or by any other means whatsoever unless the same be evidenced by Landlord’s written acceptance of such as a
surrender.

circumstances other than those as to which it is held invalid or unenforceable, shall not be affected thereby and each term or provision of this Lease shall be valid and be enforced to the fullest extent permitted by law.
