 NOW, THEREFORE, in consideration of the rents, covenants and agreements herein set forth, and for other good and valuable consideration the receipt and sufficiency of which is hereby acknowledged, the parties hereto agree as follows:

  

	1.	PREMISES AND TERM. 

  
 1.1 Premises. In consideration of the obligations of Landlord and Tenant set forth herein, Landlord leases to Tenant, and Tenant hereby takes from
Landlord the Premises identified on Exhibit A situated on real property owned by the Landlord within the Town of Blacksburg, County of Montgomery, State of Virginia more particularly described on Exhibit B attached hereto and incorporated herein by
reference (the “Property”) together with all rights, privileges, easements, appurtenances, and amenities belonging to or in any way pertaining to the Premises, to have and to hold, subject to the terms, covenants and conditions of this
Lease. Without limiting the foregoing, Tenant shall have the right, as appurtenant to the Premises, to use the driveways, parking, rear drive through door in the warehouse area of the Building and other common areas on the Property. As used in this
Lease, Tenant’s “Proportionate Share” shall mean a fraction the numerator of which shall be the square footage of the Premises (31,300 s.f.) and the denominator of which shall be the square footage of the Building (109,000 s.f.).

  
 1.2 Term. The term of this Lease (the “Term”)
shall commence on the later of (i) May 1, 2006 or (ii) the first day of the month following the completion of the improvements described in Sections 1.3 and 1.4, and reflected on Exhibit C and Exhibit D attached hereto (the
“Commencement Date”), and shall expire as of September 30, 2012, unless terminated sooner, renewed or extended as provided herein. Notwithstanding the fact that the Commencement Date is subsequent to the effective date of this Lease,
the parties agree that each 

  

 2 








 
have vested rights hereunder and that this Lease constitutes a binding and valid obligation of each as of the date this Lease is fully executed. In the event
the Term has not commenced by December 31, 2006 (“Completion Deadline Date”) because the improvements reflected on Exhibit C and Exhibit D have not been completed, Tenant may terminate this Lease and receive an immediate return of the
Letter of Credit, as defined in Section 3.1.4; provided that for each day the completion of the improvements on Exhibit C and Exhibit D is delayed due to the actions of Tenant, the Completion Deadline Date shall be extended by the same number
of days. 
  
 1.3 Acceptance of the Premises. By taking
possession of the Premises, Tenant acknowledges that: (i) it has inspected the Premises; (ii) it accepts the Premises as is, except for the separation improvements as indicated on Exhibit C to be installed by Landlord at Landlord’s
cost prior to the Commencement Date, in order to provide separate boundaries between the different tenants in the Building and the agreed upon Upfits in Section 1.4 which are indicated on Exhibit D attached hereto, (iii) the Premises are
suitable for the purpose for which the Premises are leased; and (iv) except as otherwise set forth in this Lease (including all exhibits and attachments), no representations or warranties have been made by Landlord with respect to the Premises.
Prior to the Commencement Date, it is acknowledged and agreed by Landlord that Tenant may take possession of and use the administrative offices; provided that in the event the Tenant occupies all the administrative offices, installs telephone and
internet services and begins conducting permanent business from said offices, Tenant shall pay Landlord rent on the administrative office space at the annual rate of $6.00 per sq. ft. 
  
 1.4 Upfit Allowance. The Landlord shall provide the Tenant with an improvement allowance of $15.00 per sq. ft. for a
maximum Up-fit allowance of Four Hundred Sixty Nine Thousand Five Hundred Dollars ($469,500) (the “Up-fit Allowance”). Landlord and Tenant agree that should the Tenant’s desired improvements exceed the Up-fit Allowance, the Tenant
shall provide to the Landlord the additional funds required to pay for the additional improvements. Should the desired improvements by the Tenant exceed the Up-fit Allowance, the Landlord shall have no obligation to enter into any contract for the
agreed upon Up-fit work until such time that the Tenant provides the additional funds in excess of the Up-fit Allowance. Should the Tenant not provide the Landlord with the additional funds in excess of the Up-fit Allowance within five
(5) calendar days of receiving written notice from the Landlord that the funds are due, the Landlord may deem the Tenant in default and the Landlord may, in addition to any other remedy available, use the deposit money and/or Letter of Credit
to pay all the architectural and engineering fees incurred up to the date of default. The list of improvements to be preformed by the Landlord prior to Commencement Date are indicated on Exhibit D and are incorporated herein as a part of this Lease.

  

	2.	RENEWAL; EXTENSION; SURRENDER 

  

	 	2.1	Renewal. 

  
 2.1.1 Tenant shall have the option to renew this Lease for an additional term of five (5) years on the same terms, covenants and conditions set forth herein (the “Renewal Term”); provided (i) that
this Lease is in full force and effect immediately prior to the date of the commencement of the Renewal Term and that the Tenant is not in default, beyond applicable cure periods, under any of the provisions of this Lease at the time option to renew

 3 








 
increase by the percentage increase in the CPI (as defined hereinafter) during the preceding lease year, and (iii) the Common Area Maintenance Fee shall
be subject to adjustment as provided in Section 8.1.1 The term “CPI” shall mean the Consumer Price Index published by the Bureau of Labor Statistics of the United States Department of Labor, U.S. City Average, All Items and Major

statistical information. 
  
 2.1.2 Tenant’s desire to renew
this Lease for the Renewal Term set forth above shall be expressed, if at all, by delivery of written notice (the “Renewal Notice”) to Landlord no later than 240 days prior to expiration of the initial term. Time shall be of the essence
with respect to Tenant’s Renewal Notice. 
  
 2.2 Extension
By Mutual Consent. If Tenant lawfully occupies the Premises after the end of the Term or the Renewal Term, after having requested and obtained Landlord’s written consent to do so, this Lease and all its terms, provisions, conditions,
covenants, waivers, remedies and any and all of Landlord’s rights herein specifically given and agreed to, shall be in force for one month thereafter and thereafter from month-to-month until either party gives the other thirty (30) days
written notice of its desire to terminate this Lease.

against Landlord for any damages resulting from Landlord’s retention or disposal of same. Tenant shall be entitled to no payment or offset for the value of any abandoned property (even if sold by Landlord) and Tenant shall pay on demand all
reasonable costs incurred by Landlord in connection with such removal or disposal. No retention, disposal or sale of such abandoned property shall limit remedies otherwise available to Landlord hereunder for a breach of this Agreement by Tenant. All

 3.1.2 Proration. In the event that the date on which a payment
obligation: (i) begins on a date other than the first day of a calendar month; or (ii) ends on a date other than the last day of a calendar month then the amount of the payment shall be prorated, based upon the number of days during said

 3.1.4 Letter of Credit. In addition to the required deposit, the Tenant shall cause to be put in place within five (5) business days following written notice from Landlord that construction of the improvements shown on Exhibit C
and Exhibit D is ready to commence and shall remain continuously in place until the fifth anniversary of the Commencement Date, unless otherwise provided herein or agreed by the Landlord, a letter of credit issued by a Bank in the area that is
acceptable to the Landlord in the amount of Four Hundred Sixty Nine Thousand Five Hundred Dollars ($469,500), against which the Landlord may draw upon the occurrence of an Event of Default, as defined in Section 13.1, by Tenant under this Lease
(the “Letter of Credit”). Landlord agrees that the Letter of Credit may be issued and renewed on an annual basis; provided that in the event Tenant fails to provide Landlord with a renewal Letter of Credit within ten (10) days prior
to the termination of any then existing Letter of Credit, an Event of Default as defined in Section 13.1 shall be 

  

 5 








 
deemed to have occurred. The Letter of Credit shall be provided in a satisfactory form to the Landlord and be governed by the “Uniform Customs and
Practices for Commercial Documentary Credits” promulgated by the XIII Congress of the International Chamber of Commerce (International Chamber of Commerce Brochure No. 500, 1993 revision) and the provisions of the Uniform Commercial
Code-Letters of Credit—Title 8.5 of the Code of Virginia, 1950, as amended. The Landlord agrees that so long as the Tenant is in good standing with the Lease, the amount of the Letter of Credit shall automatically be reduced at each anniversary

 4.     UTILITIES Landlord shall be responsible for providing
water, sewer, electricity and natural gas to the Premises and shall promptly pay all costs and expenses associated therewith. Tenant shall be responsible for obtaining, and paying for directly, telephone, internet and all other utilities and
services desired by the Tenant in connection with the Premises not provided by Landlord under this Lease. In the event that any of the utilities provided by Landlord are interrupted or stopped by the action or inaction of Landlord, its employees,
agents or contractors, Landlord shall, upon notice from Tenant, immediately notify the affected utility company and use its best efforts to cause repairs to be commenced. In the event that there is a utility interruption or stoppage for more than
one (1) business day, the Base Rent due hereunder shall be abated until such interruption or stoppage is corrected. In addition to the Base Rent, the Tenant shall pay Tenant’s Proportionate Share of the utilities provided by Landlord (the
“Utility Fee”). For the first six months following the Commencement Date, Tenant shall pay $3,390.83 per month based on an annual Utility Fee equal to $1.30 per square foot. At the end of the six month period following the Commencement
Date (the “Reallocation Date”), the Landlord shall determine the actual amount of Tenant’s Proportionate Share of the water, sewer, electric, and natural gas utility usage provided by Landlord during the six month period and shall
provide Tenant with a copy of readings and costs to Tenant. In the event the actual amount of Tenant’s Proportionate Share of the water, sewer, electric, and natural gas utility usage provided by Landlord during the six month period exceeds the
$1.30 per square foot amount, Tenant shall pay Landlord the difference within thirty (30) days following Tenant’s receipt of evidence of the difference. In the event the actual amount of Tenant’s Proportionate Share of the water,
sewer, electric, and natural gas utility usage provided by Landlord during the six month period following the Commencement Date is less than the annual $1.30 per square foot amount, Landlord shall reimburse Tenant the difference within thirty
(30) days following Landlord’s determination that the amount is less. For the twelve (12) month period following the Reallocation Date, Tenant shall pay a Utility Fee based on the monthly average during the preceding six month period.
At the end of the twelve (12) month period, Tenant shall pay to Landlord any increase in the actual amount of Tenant’s Proportionate Share of the water, sewer, electric, and natural gas utility usage provided by Landlord during the
preceding twelve (12) month period or Landlord shall reimburse Tenant the decrease in the actual amount of Tenant’s Proportionate Share of the water, sewer, electric, and natural gas utility usage provided by Landlord during the preceding
twelve (12) month period. For each twelve month (12) month period thereafter, Tenant shall pay a monthly Utility Fee based on the actual amount of Tenant’s Proportionate Share of the water, sewer, electric, and natural gas utility
usage provided by Landlord during the preceding twelve (12) month period. At the end of each period, Landlord shall determine the actual amount of Tenant’s Proportionate Share of the water, sewer, electric, and natural gas utility usage
provided by Landlord during the preceding twelve (12) month period, and either Tenant shall pay to Landlord any increase in the actual amount of Tenant’s Proportionate Share of the water, sewer, electric, and natural gas utility usage
provided by Landlord during the preceding twelve (12) month period or Landlord shall reimburse Tenant the decrease in the actual amount of Tenant’s 

  

 6 








 
Proportionate Share of the water, sewer, electric, and natural gas utility usage provided by Landlord during the preceding twelve (12) month period. It
is acknowledged and agreed by Landlord that Tenant shall not share in the cost and expense of the water, sewer, electric and natural gas utility usage which is separately metered to any other tenant in the Building. 
  

	5.	USE 

  
 5.1 Tenant agrees that it will use and occupy the Premises as a manufacturing, research and development facility and for such other lawful purposes as may be incident thereto and for no other purpose without
Landlord’s prior written consent, which consent shall not be unreasonably withheld, conditioned or delayed. Tenant shall comply with all governmental laws, rules, ordinances and regulations applicable to its particular use of the Premises, and
promptly comply with all governmental orders and directives for the correction and abatement of nuisances in or upon the Premises caused by Tenant, all at Tenant’s sole expense. Tenant recognizes and agrees that Landlord is making no
warranties, expressed or implied, as to the suitability of the Premises for any particular use. 
  
 5.2 Landlord represents and warrants that it has not and will not, during the Term of this Lease, enter into an agreement which limits Tenant’s
ability to use the Premises for the uses set forth in Section 5.1, except by operation of law. 
  

	6.	ALTERATIONS 

  
 6.1 Tenant shall not make any alterations, additions or improvements to the Premises, except for non-structural alterations that cost less than $50,000
per project without the prior written consent of Landlord, which shall not be unreasonably withheld, conditioned or delayed. Tenant, at its own cost and expense, may erect shelves, bins, machinery and trade fixtures as it desires provided that
(a) such items do not alter the basic character of the Premises or the Building; (b) such items do not overload or damage the same; (c) such items may be removed without material injury to the Premises; and (d) the construction,
erection or installation thereof complies with all applicable governmental laws, ordinances, regulations and all provisions of this Lease. All alterations, additions, improvements and partitions erected by Tenant shall be and remain the property of
Tenant during the Term of this Lease and shall be the property of Landlord upon the expiration or earlier termination of this Lease provided that nothing herein shall prohibit Tenant from removing the Tenant Equipment or other items, in accordance
with Section 2.3, above. All shelves, bins, machinery and trade fixtures installed by Tenant shall be removed in accordance with Section 2.3 within 30 days following the expiration or earlier termination of this Lease, at which time Tenant
shall repair any damage caused thereby, ordinary wear and tear excepted. All alterations, installations, removals and restoration shall be performed in a good, workmanlike and lien free manner. 
  
 6.2 Mechanics Liens. Tenant shall promptly pay all contractors and
material men, and will use reasonable commercial efforts to prevent any lien from attaching to the Premises or any part thereof. If any lien is filed purporting to be for labor or material furnished or to be furnished at the request of Tenant,
Tenant shall do all acts necessary to discharge such lien within twenty (20) days of filing; or if Tenant desires to contest any lien, then Tenant shall bond off the lien. In the event Tenant fails to discharge the lien or fails to pay any lien
claim after entry of final judgment in favor of the claimant, Landlord shall have the right to expend 

  

 7 








 
all sums reasonably necessary to discharge the lien claim, and Tenant shall pay all sums expended by Landlord in discharging said lien, including reasonable
attorney’s fees within thirty (30) days of receipt of the invoice. Tenant has no express or implied authority to create or place any lien or encumbrance of any kind upon, or in any manner to bind the interest of Landlord in the Premises or
to charge the rentals payable hereunder for any claim in favor of any person dealing with Tenant, including, without limitation, those who may furnish materials or perform labor for any construction or repairs requested by Tenant. 
  
 7.     SIGNAGE Tenant shall not place or permit on any
exterior door or window or any exterior wall of the Premises any sign, awning, canopy, advertising matter or lettering or at the entrance to the Property without the written consent of the Landlord, which shall not be unreasonably withheld,
conditioned or delayed. It shall not be unreasonable for Landlord to withhold its consent to the placement of any sign that does not comply with any federal, state or local law or ordinance. 
  

	8.	MAINTENANCE 

  
 8.1 Tenant’s Maintenance Responsibilities. Tenant shall at all times keep the Premises and all partitions, fixtures, equipment and
appurtenances thereof and all parts of the Premises not required in Section 8.2 to be maintained by Landlord in good order, condition and repair, and in compliance with all applicable laws, rules, ordinances and regulations, damage by casualty

 8.1.1 Common Area Maintenance Fee: Tenant shall pay, in
addition to the Base Rent, a fixed monthly fee in the amount of $912.91, based on an annual charge of $0.35 per sq. ft, to cover the cost incurred by Landlord to maintain the common areas (which includes all restrooms, hallways, conference rooms,
cafeteria, shipping and other common areas in the Building designated on Exhibit A) and exterior areas of the Building in good condition and repair, including snow removal from sidewalks and parking lots, landscaping, and grass cutting (the
“Common Area Maintenance Fee”). In the event Tenant elects to renew the term of this Lease, Landlord shall provide Tenant written evidence showing the actual costs paid by Landlord to maintain the common and exterior areas of the Building
for the twelve month period preceding the first day of the Renewal Term. The Common Area Maintenance Fee to be paid annually by Tenant during the Renewal Term shall be adjusted to equal Tenant’s Proportionate Share of the actual costs paid by
Landlord to maintain the common and exterior areas of the Building for the twelve month period preceding the first day of the Renewal Term, provided that the Common Area Maintenance Fee for the Renewal Term shall not exceed an annual charge of $0.45
per sq. ft. 
  
 8.2 Landlord’s Maintenance
Responsibilities. Landlord shall provide and keep or cause to be kept, at Landlord’s sole cost and expense, the HVAC, electrical, and plumbing systems (including any portion of the systems and the equipment related thereto located within
the Premises) and all structural portions of the Building, including without limitation, the foundation, roof, and all load bearing and exterior walls, in good order, condition and repair, except for damage thereto due to the negligence of Tenant,
Tenant’s employees or invitees. The term “exterior walls” as used herein shall include windows, glass or plate glass, doors or overhead doors, special store fronts, dock bumpers and dock plates or levelers. Landlord shall keep or
cause to be kept the parking area(s), and sidewalks in good order, condition and repair; provided Tenant shall be 

  

 8 








 
responsible for repairing any damage caused by Tenant, its employees or invitees. Tenant shall immediately give Landlord written notice of defect or need for
repairs, after which Landlord shall commence such repairs as soon as reasonably practicable. 
  
 If the parties so agree, Tenant may perform any maintenance or repair that is Landlord’s responsibility hereunder, and Landlord shall pay the cost for the maintenance or repair within thirty (30) days
following receipt of an invoice from the Tenant. 
  
 8.3
Landlord’s Failure to Make Repairs. If Landlord fails to commence any repair as required under Section 8.2 within ten (10) days after notification of the need for such repair, and fails to complete such repairs within a
reasonable period of time, Tenant may, in addition to any other remedies it may have, make such repairs at the expense of Landlord and Landlord shall pay to Tenant all costs and expenses reasonably incurred as a result of such repairs within thirty
(30) days of receipt of invoice thereof. In the event of a bona fide emergency which may result in damage or injury to persons or Tenant’s property, damage which has a material impact on Tenant’s ability to conduct business as
contemplated under this Agreement, or damage which otherwise exposes Tenant (in Tenant’s reasonable judgment) to liability, Tenant may, unless Landlord commences and diligently pursues such repairs within five (5) days after receipt of
written notice (or such shorter period as would reasonably be expected under the given circumstances), make such repairs on behalf of Landlord and Landlord shall pay to Tenant all costs and expenses reasonably incurred in making such repairs within
thirty (30) days of receipt of invoice thereof. 
  

	9.	ASSIGNMENT AND SUBLETTING 

  
 9.1 Assignment or Subletting by Tenant. Tenant shall not, either voluntarily or by operation of law, assign, transfer, mortgage, pledge,
hypothecate or encumber this Lease, or any interest therein, and shall not sublet the Premises, or any part thereof, without obtaining the prior written consent of Landlord, which consent shall not be unreasonably withheld, conditioned or delayed.
In connection with any such assignment or sublease, Tenant or the assignee or subtenant of Tenant shall pay to Landlord any legal and administrative costs incurred by Landlord in approving such assignment or subletting, not to exceed $750.00. The
acceptance of rent from any other party shall not be deemed to be a waiver of any of the provisions of this Lease, or deemed consent to the assignment or subletting of the Premises. Consent to any assignment or subletting shall not be deemed consent
to any future assignment or subletting. Notwithstanding the foregoing, Tenant shall have the absolute right (without obtaining Landlord’s prior written consent which shall not be required) to assign this Lease in whole or in part or to sublet
all or any portion of the Premises to: any affiliate controlling, controlled by or under common control with Tenant; an entity into which Tenant merges or consolidates; or to a purchaser of all or substantially all of the assets of Tenant, if the
assignee or sublessee agrees, in writing delivered to Landlord, to abide by all the provisions under this Lease. 
  
 9.2 Assignment by Landlord. Landlord may assign this Lease, in whole or in part, without the prior written consent of Tenant, provided that such
assignment does affect or impair the rights granted to Tenant herein, or adversely affect Tenant’s possession of the Premises. Notwithstanding the foregoing, if this Lease is assigned, in whole or in part, by The Industrial Development
Authority of Montgomery County, 

  

 9 








 
Virginia, any subsequent assignment of this Lease, in whole or in part, shall require the prior written consent of Tenant. 
  
 9.3 Assignment pursuant to Provision of the Bankruptcy Code. If this
Lease is assigned to any person or entity pursuant to the provisions of the Bankruptcy Code (11 U.S.C. sec. 101 et seq), any and all monies or other considerations payable or otherwise to be delivered in connection with such assignment shall be paid
or delivered to the Landlord and shall be and remain the exclusive property of the Landlord and shall not constitute the property of the Tenant or the estate of the Tenant, within the meaning of the Bankruptcy Code. 
  
 10.     RIGHT OF ENTRY Landlord, its employees and agents,
shall have the right to enter the Premises with a designated representative of Tenant upon reasonable notice during regular business hours for the purpose of examining or inspecting the same, showing the same to prospective purchasers, mortgagees or
tenants of the Premises, and to perform its maintenance obligations under Section 8.2, above. In the case of a bona fide emergency, Landlord shall use its best efforts to provide Tenant with the greatest possible notice under the circumstances
prior to entering the Premises and in the event that representatives of Tenant are not present to accompany Landlord or to open and permit entry into the Premises during the course of a bona fide emergency, then Landlord may enter the Premises
forcibly and without being accompanied by a representative of Tenant without such entry constituting an eviction of Tenant or termination of this Lease. Except in the case of a bona fide emergency, Landlord, its employees and agents shall abide by
all reasonable security and safety procedures established for the Premises by Tenant. 
  

	11.	INSURANCE 

  
 11.1 Landlord’s Obligations. Throughout the Term of this Lease, including any renewals or extensions thereof, Landlord shall maintain the

substantially similar buildings, including but not limited to coverage for loss of rent. All insurance coverage shall be primary and non-contributory and issued by insurers licensed to do business in the state in which the Premises are located. The
insurance required of Landlord hereunder may be maintained by a blanket or master policy, which includes properties other than the Premises. 
  

	 	11.2	Tenant’s Obligations. 

  
 11.2.1 Tenant shall keep in effect at Tenant’s expense during the term of this Lease: (i) all risk property insurance covering the full

30-days prior notification of cancellation or material change in coverage to said Landlord. Tenant may comply with its insurance obligations hereunder in whole or in part through a company-wide program of self-insurance and may maintain company-wide
levels of deductibles provided the Tenant provides Landlord with an appropriate self-insurance certificate. 
  
 11.2.2 Fire and Casualty Insurance. Tenant shall not do or suffer to be done any act, matter or thing whereby the fire and casualty insurance
carried by Landlord on the Building of which the Premises are a part shall be suspended or rated as more hazardous than at the commencement of this Lease. In case of breach of this covenant, Tenant agrees to pay, within thirty (30) days of
receipt of written demand, any and all increase of premium for fire and casualty insurance carried by Landlord caused directly by the actions or occupancy of Tenant. 
  

	12.	DAMAGE OR DESTRUCTION OF LEASED PREMISES 

  
 12.1 If the Premises are damaged by fire or any other cause which renders the Premises completely untenantable, in Tenant’s reasonable determination,
then Tenant by a notice in writing sent no later than thirty (30) days after such damage may terminate this Lease as of the date of such damage, and any Base Rent or other amounts for the unexpired period paid in advance beyond the date of such
damage, shall be refunded by Landlord to Tenant and the original Letter of Credit shall be returned promptly to Tenant. 
  
 12.2 If Tenant does not elect to terminate this Lease as provided in Section 12.1 or if the Premises are not rendered completely untenantable,
Landlord shall diligently commence restoration and restore the Premises to a condition equal to its condition before the damage; provided that Landlord’s obligation to repair and restore the Premises is contingent upon its receipt of insurance
proceeds sufficient to make such repairs. In the event any mortgagee or lender requires any insurance proceeds to be applied to any debt, Landlord shall not be deemed to have received the proceeds, in which event Tenant may terminate this Lease
unless Landlord agrees to fund the repairs. If Landlord completes such repairs, then Tenant shall promptly repair or replace its trade fixtures, furnishings, furniture, carpeting, wall covering, floor covering, drapes and equipment to the same
condition as they were in immediately prior to the casualty. The Base Rent and other amounts owed hereunder, according to the extent that such damage and its repair shall interfere with the full enjoyment and use of the Premises, shall be suspended
and abated from the date of such damage until Landlord’s repairs have been completed. In the event that the Premises have not been restored to a condition equal to their condition before the damage within ninety (90) days after
Landlord’s receipt of the proceeds, then Tenant may, by a notice in writing sent prior to completion of restoration, terminate this Lease as of the date of such termination, and any Base Rent or other amounts for the unexpired period paid in
advance beyond the date of such damage, shall be refunded by Landlord to Tenant and the original Letter of Credit shall be returned promptly to Tenant. 
  

	13.	REMEDIES OF LANDLORD UPON TENANT’S DEFAULT 

  
 13.1 Tenant’s Default Defined. The following shall be considered an “Event of Default” and a breach of this Lease: (a) any
failure of Tenant to pay any Base Rent, the Utility Fee, the Common Area Maintenance Fee, the money in the excess of the Up-fit Allowance or other amounts due hereunder for more than five (5) business days after receipt of written notice of
non-payment; (b) any failure by Tenant to perform 

  

 11 








 
or observe any of the other terms, provisions, conditions and covenants of this Lease for more than thirty (30) days after receipt of written notice of
such failure provided, however, that if the event for which the notice is given is of a nature that may not be reasonably cured within said thirty (30) day period, Tenant shall not be in default for so long as Tenant commences to cure the
default within the thirty (30) day period and diligently pursues it to conclusion; (c) Tenant files a voluntary or involuntary petition in bankruptcy which is not dismissed within thirty (30) days of the filing or makes a general
assignment for the benefit of its creditors; (d) a receiver of any property of Tenant in or upon the Premises is appointed in any action, suit, or proceeding by or against Tenant and such appointment shall not be vacated or annulled within
sixty (60) days; or (e) this Lease, Tenant’s interest herein or in the Premises, any improvements thereon, or any property of Tenant is executed upon or attached. 
  
 13.2. Landlord’s Remedies. Upon the occurrence of any Event of Default specified in Section 13.1, Landlord,
in addition to all other rights or remedies Landlord may have for such default at law or in equity, shall have the right to pursue any one or more of the following remedies. 
  
 13.2.1 Terminate this Lease and, without prejudice to any other remedy which it may have for possession or arrearages in
Base Rent or other amounts owed hereunder, enter upon and take possession of the Premises by summary dispossession proceedings or any other method authorized by law and recover from Tenant through the Deposit money paid pursuant to Paragraph 3.1.3
and/or the Letter of Credit provided pursuant to Paragraph 3.1.4 or by other legal means: (i) all Base Rent and other amounts due and unpaid up to the time of re-entry; (ii) the costs of repairing or otherwise putting the Premises into the
condition required by this Lease; and (iii) Tenant shall continue to be liable to pay the Base Rent and other amounts owed hereunder as they become due, reduce by Landlord’s net re-letting proceeds. 
  
 13.2.2 Without terminating this Lease, enter upon and take possession of the
Premises, by summary dispossession proceedings or any other remedy authorized by law and re-let the Premises, or any part thereof, for such term or terms (which may extend beyond the term of this Lease), for the highest rent reasonably obtainable
(even if such rent is below market value) and to recover from Tenant the difference between the Base Rent reserved by this Lease and the amount obtained through such re-letting plus the following costs, if reasonably incurred by Landlord in such
re-letting: (a) brokerage fees and/or leasing commissions; (b) the costs of removing and storing Tenant’s or any other occupant’s property; and (c) the costs of repairing or otherwise putting the Premises into the condition
required by this Lease together with the costs of alterations reasonably necessary to re-let the Premises. No such re-letting shall relieve Tenant from its obligations hereunder. In no event shall Tenant be entitled to any excess rent obtained by
re-letting the Premises over and above the Base Rent reserved herein. 
  
 13.3 If the Tenant shall continue in default in the performance of any of the covenants or agreements herein contained, after any applicable cure period, Landlord may perform the same for the account of Tenant. Any amount incurred by
Landlord in the performance of any such matter for the account of Tenant shall be payable by Tenant to Landlord within thirty (30) days after written demand and evidence that the same has been paid. 
  
 13.4 No re-entry or taking possession of the Premises by Landlord shall be
construed as an election to terminate this Lease unless Landlord sends a written notice of termination to Tenant. Pursuit of any of the 

  

 12 








 
foregoing remedies shall not preclude pursuit of any of the other remedies herein provided or any other remedies provided by at law or in equity, nor shall
pursuit of any remedy herein provided constitute a forfeiture or waiver of any Base Rent, or other amounts due to Landlord hereunder or of any damages accruing to Landlord. 
  

	14.	REMEDIES OF TENANT UPON LANDLORD’S DEFAULT 

  
 14.1 Landlord shall be in default of this Lease (a “Landlord Default”) if it shall fail to perform any duty or obligation imposed upon it by
this Lease and such failure shall continue for a period of thirty (30) days after written notice, provided, however, that if the event for which the notice is given is of a nature that may not reasonably be performed within said thirty
(30) day period, Landlord shall not be in default for so long as Landlord commences its performance within said thirty day period and diligently pursues it to conclusion. Upon the occurrence of a Landlord Default, Tenant, in addition to all
other rights or remedies Tenant may have for such default at law or in equity, shall have the right to exercise any self-help measures as may be reasonably necessary to cure such default. Landlord shall reimburse any costs and expenses incurred by
Tenant in order to cure a Landlord Default within thirty (30) days after written demand and evidence that the same has been paid. In addition, if Landlord fails to cure any default within thirty (30) days after receiving written notice of
the default, Tenant shall have the right, upon written notice to Landlord, to terminate this Lease without penalty or further obligation to Landlord, its employees, officers, agents or lenders. 
  
 14.2 All obligations of Landlord under this Lease will be deemed binding upon
Landlord only during the period of its ownership of the Premises and not thereafter; provided that Landlord or any subsequent owner of the Premises shall not be released from any liability arising under this Lease during such parties’ ownership
of the Premises. 
  
 15.    EMINENT DOMAIN In the event
that the Premises, in whole or in part, are taken by paramount governmental authority or in any way condemned or appropriated by the exercise of the right of eminent domain or a deed or conveyance in lieu of eminent domain (each a
“Taking”) such that Tenant’s is unable to use the Premises for the purposes set forth herein, Tenant shall have the right, at its option, within sixty (60) days after said Taking, to terminate this Lease upon thirty
(30) days written notice to the Landlord. In the event Tenant elects to terminate the Lease, the Base Rent and other amounts owed under this Lease shall be abated from the date of the Taking, and Tenant’s liability therefore will cease as
of the date of such termination, and any prepaid Base Rent or other amounts shall be returned to Tenant, along with the original Letter of Credit. If this Lease is not terminated as provided in this Section 15 then it shall continue in full
force and effect (provided no Base Rent or other amounts shall be owed by Tenant until the remainder of the Premises are restored, however, Tenant shall pay prorata Base Rent on any space Tenant occupies prior to the restoration of the Premises),
and Landlord shall within a reasonable time after possession is physically taken by the condemning authority restore the remaining portion of the Premises to render it reasonably suitable for the uses permitted by this Lease and the Base Rent and
other amounts owed hereunder shall be proportionately and equitably reduced. If the proceeds received in connection with the Taking are not sufficient to restore the remaining portion of the Premises to render it suitable for the uses permitted by
this Lease and the Landlord is unwilling to pay the difference, Tenant may terminate this Lease. In the event any mortgagee or lender requires that all or any portion of the proceeds received from the condemning authority be applied to any debt,
Landlord will not be deemed to have received such proceeds. All compensation awarded in connection with or 

  

 13 








 
as a result of a Taking shall be the property of the Landlord, except that Tenant may apply for and keep as its property a separate award for: (i) the
value of Tenant’s leasehold interest; (ii) the value of Tenant Equipment or Tenant’s trade fixtures or personal property; (iii) Tenant’s moving expenses; (iv) Tenant’s business relocation expenses; and
(v) damages to Tenant’s business incurred as a result of such Taking. 
  

	16.	SUBORDINATION OF LEASE 

  
 16.1 This Lease is and shall remain subordinate and subject to any mortgage or mortgages or deed of trust which are now, or at any time hereafter shall be
placed, upon the interest of Landlord in the Premises or any part thereof or to any assignment of the interest of Landlord in this Lease; provided that the holder thereof shall execute and deliver to Tenant a non-disturbance agreement in form
reasonably acceptable to Tenant. Tenant agrees to execute and deliver to Landlord, without cost, any instrument that may be deemed necessary by Landlord to further effect the subordination of this Lease to any such mortgage, mortgages or assignments
in form reasonably acceptable to Tenant. 
  
 16.2 In the event of
a foreclosure of any such mortgage, Landlord and Tenant hereby agree that this Lease shall not terminate by reason thereof, and Tenant further agrees to recognize as Landlord hereunder the mortgagee or purchaser at a foreclosure sale for the balance
of the Term, the Renewal Term or an extension of either, subject to all the terms and provisions hereof; provided, however, that any such mortgagee or purchaser at a foreclosure sale, which shall become the Landlord hereunder, shall not be:

  
 (a) liable for acts or omissions of Landlord occurring prior
to its ownership of the Premises (but such mortgagee or purchaser shall perform any unperformed obligations under this Lease existing at the time it becomes Landlord); 
  
 (b) subject to any offsets or defenses which Tenant might have against Landlord that accrue prior to its ownership of the
Premises, except as provided in this Lease; 
  
 (c) bound by any
Base Rent or other amounts which Tenant may have paid to Landlord more than thirty days in advance (other than the security deposit); or 
  
 (d) bound by any amendment or modifications of said Lease made after Tenant receives written notice of such foreclosure. 
  
 17.    ESTOPPEL CERTIFICATE Either party shall, at any time and
from time to time within twenty (20) days following receipt of written request from the other party, execute, acknowledge and deliver to the requesting party a written statement certifying that this Lease is in full force and effect and
unmodified (or, if modified, stating the nature of such modification), certifying the date to which the Base Rent reserved hereunder has been paid, and certifying that there are not, to the responding party’s knowledge, any uncured defaults on
the part of the party requesting the certificate, or specifying such defaults if any are claimed. Such a statement may be relied upon by any prospective purchaser, mortgagee or subtenant of all or any portion of the Premises. The responding
party’s failure to deliver such statement within said twenty-day period shall be conclusive upon such party that this Lease is in full force and effect and unmodified, and that there are no uncured defaults in the requesting party’s
performance hereunder. 
  

 14 








 18.    RULES AND REGULATIONS Tenant and Tenant’s agents, employees and invitees shall
faithfully observe and comply with all reasonable, uniform rules and regulations promulgated by Landlord from time to time for the safety, care or cleanliness of the Premises and for the preservation of good order therein, provided that such rules
and regulations do not materially increase Tenant’s duties or obligations under this Lease. In the event of any conflict or inconsistency between the terms and conditions of this Lease and any rules and regulations promulgated by Landlord, the
conflict or inconsistency shall be resolved by giving precedence to the terms and conditions of this Lease. 
  
 19.    QUIET ENJOYMENT Landlord represents and warrants that it has the authority to enter into this Lease. Landlord further represents, warrants and covenants that so long as Tenant pays
all amounts due hereunder and performs all other material covenants and conditions of this Lease to be performed by the Tenant hereunder, Landlord and its successors and assigns shall not interfere, nor permit interference, with Tenant’s quiet
use and enjoyment of the Premises and that, subject to the terms and conditions of this Lease, Tenant shall peaceably and quietly have, hold and enjoy the Premises for the Term hereof.
