 10. Subordination and Modification 

10.1 Subordination of Lease. Without the necessity of any additional document being executed by Tenant for the purpose of
effecting a subordination, Tenant agrees that this Lease and Tenant’s tenancy hereunder are and shall be automatically subject and subordinate at all times to (a) all ground leases or underlying leases that may now exist or hereafter be
executed affecting the Building or the Real Property or both, (b) the lien of any mortgage deed of trust or similar security instrument that may now exist or hereafter be executed in any amount for which the Building, the Real Property, ground
leases or underlying leases, or Landlord’s interest or estate in any of said items is specified as security, and (c) all renewals, modifications, consolidations, replacements and extensions of any of the foregoing, provided the same does
not materially alter the terms of this Lease 
 Tenant covenants and agrees to execute and deliver, upon demand by Landlord and
in the form requested by Landlord, any additional documents evidencing the subordination of this Lease with respect to any such ground lease or underlying lease, or the lien of any such mortgage or deed of trust. If Tenant fails to execute such
instruments within fifteen (15) days after written request therefor, Landlord is hereby appointed Tenant’s attorney-in-fact to execute, acknowledge and deliver any and all such instruments for and on behalf of Tenant, provided the same
does not materially alter the terms of this Lease. 
 10.2 Attornment. In the event that any ground lease or underlying
lease terminates for any reason or any mortgage or deed of trust is foreclosed or a conveyance in lieu of foreclosure is made for any reason, Tenant shall, notwithstanding any subordination of any ground lease, underlying lease or lien to this
Lease, attorn to and become the Tenant of the successor in interest to Landlord at the option of such successor in interest. 

10.3 The foregoing notwithstanding, subordination of this Lease to any mortgage and attornment by Tenant pursuant to Section 10.2
is conditioned on the holder of such mortgage executing a nondisturbance agreement in favor of Tenant. 
 11. Inability
to Perform; No Delay to Constitute Eviction. If, for any reason, Landlord or Tenant is unable to perform or make or is delayed in fulfilling any of its obligations under this Lease, and such failure arises from or through acts of God, strikes,
lockouts, labor difficulties, explosions, sabotage, accidents, riots, civil commotions, acts of war or warlike conditions in this country, fire and casualty, legal requirements, energy shortage or causes beyond the reasonable control of Landlord or
Tenant, no such inability or delay shall constitute an actual or constructive eviction, in whole or in part, or entitle Tenant to any abatement or diminution of Basic Rent or Additional Rent, or relieve Tenant from any of its obligations under this
Lease, or impose any liability upon Landlord or its agents by reason of inconvenience or annoyance to Tenant or by reason of injury to or interruption of Tenant’s business, or otherwise. 

12. Destruction 
 12.1 Damages Caused By Tenant. Subject to the provisions of section 8.1 all injury to the demised premises and other portions of the building of which it is a part, caused by Tenant, its agents,
employees, invitees and visitors, will be repaired by Landlord at the expense of Tenant except as provided in Section 8.2, or repaired by Tenant with Landlord’s approval in accordance with Section 8. Tenant shall reimburse Landlord
for such repairs within ten (10) days of receipt of invoice from Landlord of the costs. At its election, Landlord may regard the same as additional rent, in which event the cost shall become additional rent payable with the installment of rent
next becoming due after notice is received by Tenant from Landlord. This provision shall be construed as an additional remedy granted to Landlord and not limitation of any other rights and remedies, which Landlord has or may have in said
circumstances. 
 Fire or Casualty Damage. In the event of damage or destruction of the demised premises by fire or any
other casualty without the fault or neglect of Tenant, its agents, employees, invitees and visitors, this Lease shall not be terminated, but structural damage to the premises including demising partition and doors shall be promptly and fully
repaired and restored as the case may be by Landlord at its own cost and expense. Due allowance, however, shall be given for reasonable time required for adjustment and settlement of insurance claims, and for such other delays as may result from
government restrictions and controls on construction, if any and for strikes, national emergencies and other conditions beyond the control of Landlord. Restoration by Landlord shall not include replacement of furniture, equipment or other items that
do not become part of the building or any improvements to the demised premises in excess of those provided for as building standard items as of the commencement date of this Lease. Tenant shall be responsible for the repair and restoration of the
demised premises and Tenant’s property beyond Landlord’s obligation at no cost to Landlord, in accordance with the provisions of Section 8, for which it shall maintain adequate insurance pursuant to section 18.3 herein. In the event
of fire or casualty damage to the demised premises caused by the fault or neglect of Tenant, its agents, employees, invitees or visitors. Landlord shall restore structural damages as described herein at Tenant’s cost and expense. It is agreed
that in any of the aforesaid events, this Lease shall continue in full force and effect. 
 12.2 Termination of Lease in the
Event of Total Destruction. Notwithstanding the provisions of Section 12.1 hereof, if, prior to or during the Term (a) the Premises shall be totally damaged or rendered wholly untenantable by fire or other casualty, and if Landlord
shall determine, in its sole discretion, not to restore the Premises, or (b) the Building shall be so damaged by fire or other casualty that, in Landlord’s opinion, substantial alteration, demolition or reconstruction of the Building shall
be required (whether or not the Premises shall have been damaged or rendered untenantable), then, in any of such events, Landlord, at Landlord’s option, may give to Tenant within Ninety (90) days after such fire or other casualty, a thirty
(30) days’ notice of termination of this Lease and, in the event such notice is given, this Lease and the Term shall terminate upon the expiration of such thirty (30) days with the same effect as if the date of expiration of such
thirty (30) days were the Term Expiration Date; and the Basic Rent and Additional Rent shall be apportioned as of such date and any prepaid portion of Basic Rent or Additional Rent for any period after such date shall be refunded by Landlord to
Tenant-notice to Tenant as of the date of actual loss. Unless Tenant is able to conduct business in the Premises, such notice shall effect the termination of this Lease and the Basic Rent and any Additional Rent shall be apportioned as of such date
and any prepaid portion of the Basic Rent or Additional Rent for any period after such date shall be refunded by Landlord to Tenant. 

  
 - 6 -









 12.3 Landlord’s Insurance. Landlord shall obtain and maintain, throughout the
Term, in Landlord’s casualty insurance policies, provisions to the effect that such policies shall not be invalidated should the insured waive, in writing, prior to loss, any or all right, of recovery against any party for loss occurring to the
Building. In the event that at any time Landlord’s casualty insurance carriers shall exact an additional premium for the inclusion of such or similar provisions, Landlord shall give tenant notice thereof. In such event, if Tenant agrees, in
writing, to reimburse Landlord for such additional premium for the remainder of the Term, Landlord shall require the inclusion of such or similar provisions by Landlord’s casualty insurance carriers. As long as such or similar provisions are
included in Landlord’s fire insurance policies then in force, Landlord hereby waives any right of recovery against Tenant, any other permitted occupant of the Premises, and any of their servants, employees, agents or contractors, for any loss
occasioned by fire or other casualty that is an insured risk under such policies. In the event that at any time Landlord’s casualty insurance carriers shall not include such or similar provisions in Landlord’s fire insurance policies, the
waivers set forth in the foregoing sentence shall be deemed of no further force or effect. 
 12.4 Tenant not Relieved from
Liability. Except to the extent expressly provided in Section 12.3 hereof, nothing contained in this Lease shall relieve Tenant of any liability to Landlord or to its insurance carriers which Tenant may have under law or under the
provisions of this Lease in connection with any damage to the Premises or the Building by fire or other casualty. 
 12.5 No
Abatement of Rent if Damage Caused by Tenant. Notwithstanding the foregoing provisions of Section 12 hereof, if any such damage is due to the fault or neglect of Tenant, any person claiming through or under Tenant, or any of their servants,
employees, agents, contractors, visitors or licensees, then there shall be no abatement of Basic Rent or Additional Rent by reason of such damages, unless Landlord is reimbursed for such abatement of Basic Rent or Additional Rent pursuant to any
rental insurance policies that Landlord may, in its sole discretion, elect to carry. 
 13. Eminent Domain 

13.1 Total Condemnation. If all of the Premises is condemned or taken in any manner for public or quasi-public use, including but
not limited to a conveyance or assignment in lieu of a condemnation or taking, this Lease shall automatically terminate as of the date of dispossession of Tenant as a result of such condemnation or other taking. If a part of the Premises is so
condemned or taken, this Lease shall automatically terminate as to the portion so long as Tenant is able to conduct business within the remaining portion of the Premises, of the Premises so taken as of the date of dispossession of Tenant as a result
of such condemnation or taking. If such portion of the Building is condemned or otherwise taken so as to require, in the opinion of Landlord, a substantial alteration or reconstruction of the remaining portions thereof, this Lease may be terminated
by Landlord, as of the date of dispossession of Tenant as a result of such condemnation or taking, by written notice to Tenant within sixty (60) days following notice to Landlord as of the date on which said dispossession will occur.

 13.2 Landlord Entitled to Award. Landlord shall be entitled to the entire award in any condemnation proceeding or
other proceeding for taking for public or quasi-public use, including, without limitation, any award made for the value of the leasehold estate created by this Lease. No award for any partial or entire taking shall be apportioned, and Tenant hereby
assigns to Landlord any award that may be made in such condemnation or other taking, together with any and all rights of Tenant now or hereafter arising in or to same or any part thereof; provided, however, that nothing contained herein shall be
deemed to give Landlord any interest in or to require Tenant to assign to Landlord any separate award made to Tenant specifically for its relocation expenses, the taking of personal property and fixtures belonging to Tenant or the interruption of or
damage to Tenant’s business. Tenant shall be entitled to moving expenses. 
 13.3 Partial Condemnation. In the event
of a partial condemnation or other taking that does not result in a termination of this Lease as to the entire Premises, the Basic Rent and Additional Rent shall abate in proportion to the portion of the Premises taken by such condemnation or other
taking. 
 13.4 No Termination of Lease. If all or any portion of the Premises is condemned or otherwise taken for public
or quasi-public use for a limited period of time, this Lease shall remain in full force and effect and Tenant shall continue to perform all of the terms, conditions and covenants of this Lease, and Basic Rent and Additional Rent shall abate in
proportion to the portion of the Premises taken during such temporary condemnation or other taking. 
 14. Assignment and
Subletting. 
 14.1 No Assignment or Subletting Permitted. Tenant shall not directly or indirectly, voluntarily or by
operation of law, sell, assign, sublease, encumber, pledge or otherwise transfer or hypothecate all or any part of the Premises or Tenant’s leasehold estate hereunder, without first obtaining Landlord’s prior written consent, which will
not be unreasonably withheld or delayed. Notwithstanding the foregoing, a corporate reorganization within the meaning of Section 368 of the Internal Revenue Code of 1986 shall not be considered an assignment or subletting within the meaning of
this Section 14.1. Tenant agrees that any permitted assignment or subletting hereunder may be conditioned upon payment of consideration to be agreed upon by Landlord and Tenant. If Tenant allows another medical device company to share the
Premises utilizing the same common areas, this shall not be considered a sublet and Landlord’s approval or notification shall not be required.

which notice shall contain (a) the name of the proposed occupancy or subtenant, (b) the nature of the proposed occupant’s or subtenant’s business to be carried on in the Premises, (c) the portion(s) of the Premises to be
subject to such assignment or sublease and the other terms and provisions of the proposed assignment or sublease, (d) such financial information as Landlord may reasonably request concerning the proposed occupant or subtenant, and (e) a
true copy of a proposed assignment or sublease.

 14.3 No Release of Tenant. No assignment or sublease by Tenant shall relieve Tenant
of any obligation to be performed by Tenant under this Lease, whether arising before or after the assignment or sublease. Any assignment or sublease that is not in compliance with this Section 14 shall be void and, at the option of Landlord,
shall constitute a default by Tenant under this Lease. 
 15. Utilities and Services 

15.1 Tenant’s Expense. Tenant shall at its own expense, pay to appropriate utility companies for all charges for such
utilities consumed in the Premises as and when such charges become due and payable. If any such utilities are not separately metered, Tenant shall pay to Landlord its allocable share of such utilities as are reasonably determined by Landlord. Tenant

Section 16.1; provided, however, that with respect to any such default that cannot reasonably be cured within the ten (10) day grace period, Tenant shall not be deemed in default if Tenant commences to cure within ten (10) days from
Landlord’s notice and continues to prosecute diligently the curing thereof to completion within a reasonable time; and provided, further, that if any such failures which would be deemed defaults hereunder upon expiration of such grace period
occur more often that twice in any twelve month period, the foregoing requirements of written notice and a grace period shall be deemed waived with respect to any such subsequent failures for the remainder of the Term. 

(c) If any representation or warranty made by Tenant, or others on behalf of Tenant, under or pursuant to the Lease shall prove to have
been false or misleading in any material respect (including by way of material omissions) as of the date on which such representation or warranty was made.

petition in any bankruptcy or insolvency proceeding, or an involuntary petition in bankruptcy or insolvency proceeding is filed against Tenant and not discharged or dismissed within thirty (30) days, or Tenant is adjudicated bankrupt or admits
in writing its inability to pay its debts or that it is insolvent.

reasonable opinion of the Landlord, the entry of a final judgment for the payment of money in excess of $200,000.00 against the Tenant and the failure by the Tenant to discharge the same, or cause it to be discharged, or bonded off to the
Landlord’s satisfaction, within thirty (30) days from the date of the order, decree or process under which or pursuant to which such judgment was entered. 
 (f) If Tenant shall dissolve or liquidate, and such dissolution or liquidation is not in connection with a reorganization, merger or consolidation approved in writing by Landlord. 

16.2 Landlord’s Remedies. Upon the occurrence of an Event of Default, which is not cured by Tenant within the grace periods
specified in Section 16.1 hereof, Landlord shall have the following rights and remedies in addition to all other rights or remedies available to Landlord in law or equity: 

(a) Landlord may terminate this Lease by notice to Tenant (and Tenant hereby expressly waives any other or additional notice to quit or
notice of Landlord’s intention to re-enter), whereupon this Lease and the Term shall terminate, Tenant shall quit, vacate and surrender the Premises and all amounts accrued and unpaid Basic rent and Additional Rent shall be due and payable in
full. 
 (b) Upon any termination of this Lease pursuant to Section 16.2(a) or Section 17, Landlord may
(i) proceed to re-enter the Premises and recover possession thereof; (ii) as attorney-in-fact for Tenant, remove therefrom all persons and Tenant’s Property, store such Tenant’s Property in a public warehouse or elsewhere at the
cost, and for the account, of Tenant, sell such Tenant’s Property and apply the proceeds thereof to payment of Tenant’s obligations and liabilities under this Lease, and hold the balance of such proceeds, if any, in trust for Tenant;
(iii) restore the Premises to good order and repair or otherwise prepare the Premises for reletting by making such reasonable alterations, repairs or replacements in the Premises as Landlord, in its sole discretion deems necessary or
appropriate; and (iv) relet the Premises for such rent, for such term (which may be longer or shorter than the Term originally reserved hereunder) and upon such other terms and conditions as are not unreasonable under the circumstances. Tenant
shall be liable for all damages sustained by Landlord in connection with such termination of this Lease, including without limitation the excess of the aggregate amounts of Basic Rent and Additional Rent reserved under this Lease for the Term
originally reserved hereunder over net amounts actually realized in reletting the Premises, reasonable attorneys’ fees, brokerage commissions and the costs and expenses of recovering possession of the Premises and restoring the Premises to
first class condition for reletting. 
 Any such damages may, at Landlord’s election, be recovered in one or more actions
upon termination of the Term, at the time of any initial reletting or from time to time as such damages may become more easily ascertainable by successive relettings. In no event shall Landlord be liable for any failure to relet the Premises or for
any failure to collect any amounts due on account of relettings and in no event shall Tenant have any right to any excess of amounts received by Landlord on account of relettings over amounts which Tenant may be liable hereunder. 

  
 - 8 -









 (c) Landlord may elect not to terminate this Lease but to recover the Basic Rent and
Additional Rent accruing hereunder in one or more actions as the same become due or, in advance, the present value of Basic rent and Additional Rent to become due hereunder, discounted by a factor of eight percent (8%) per annum; or, as for
Tenant, Landlord may from time to time sublet the Premises or any part thereof for such term or terms and at such rent and such other terms as Landlord in its sole discretion may deem advisable, with the right to make alterations and repairs to the
Premises. Upon each such subletting (i) Tenant shall be immediately liable for payment to Landlord of, in addition to Basic Rent and Additional Rent due hereunder, the cost of such subletting and such alterations and repairs incurred by
landlord and the amount, if any, by which the Basic Rent and Additional Rent for the period of such subletting (to the extent such period does not exceed the Term) exceeds the amount to be paid as Basic Rent and Additional Rent for the Premises for
such period, or (ii) at the option of Landlord, rents received from such subletting shall be applied, first, to payment of any indebtedness other than Basic Rent and Additional Rent due hereunder from Tenant to Landlord; second, to the payment
of any costs of such subletting and of such alterations and repairs; third, to payment of Basic Rent and Additional Rent due and unpaid hereunder; and the residue, if any, shall be held by Landlord and applied in payment of future Basic Rent and
Additional Rent as the same become due hereunder. 
 If Tenant has been credited with any rent to be received by such
subletting under clause (i) and such rent shall not be promptly paid to Landlord by the subtenant(s), or if such rentals received from such subletting under clause (ii) during any month are less than those to be paid during that month by
Tenant hereunder, Tenant shall pay any such deficiency to Landlord. Such deficiency shall be calculated and paid monthly. No subletting of the Premises by Landlord, as attorney-in-fact for Tenant, shall be construed as an election on its part to
terminate this Lease unless a notice of such termination is given to Tenant. Notwithstanding any such subletting without termination, Landlord may at any time thereafter elect to terminate this Lease for such previous breach; and 

(d) Landlord may have a receiver appointed for Tenant, upon application by Landlord, to take possession of the Premises and to apply any
rental collected from the Premises and to exercise all other rights and remedies granted to Landlord as attorney-in-fact for Tenant pursuant to Section 16.2(b) hereof. 
 (e) Tenant hereby expressly and unconditionally waives, in connection with any suit, action or proceeding brought by Landlord under this Lease, any and every right it may have to (i) injunctive
relief, (ii) a trial by jury, (iii) interpose any counterclaim therein and (iv) have the same consolidated with any other or separate suit, action or proceeding. Nothing herein contained shall prevent or prohibit Tenant from instituting or
maintaining a separate action against Landlord with respect to any asserted claim. 
 17. Insolvency or Bankruptcy. Upon
the appointment of a receiver to take possession of all or substantially all of the assets of Tenant, or an assignment by Tenant for the benefit of creditors, or any action taken or suffered by Tenant under any insolvency, bankruptcy,
reorganization, moratorium or other debtor relief act or statute, whether now existing or hereafter amended or enacted, this Lease shall automatically terminate without notice or other action by Landlord or Tenant; provided further, that Landlord
shall have the right, within thirty (30) days after Landlord has actual knowledge of the events effecting such termination, to revoke such termination and reinstate this Lease retroactively to the date of such termination. Upon, and at any time
after, such termination, Landlord shall have the right to exercise the remedies reserved under Section 16.2(b). In no event shall this Lease or any rights or privileges hereunder be an asset of Tenant under any bankruptcy, insolvency,
reorganization or other debtor relief proceedings. 
 18. Fees and Expenses; Indemnity; Liability Insurance 

18.1 Performance by Landlord. If Tenant shall default in the performance of its obligations under this Lease, Landlord, at any
time thereafter and without notice, may remedy such default for Tenant’s account and at Tenant’s expense, without thereby waiving any other rights or remedies of Landlord with respect to such default. 

18.2 Indemnification by Tenant. 
 (a) Tenant agrees to indemnify Landlord, its employees, agents, contractors, mortgagees and successors in interest against and save Landlord, its employees, agents, contractors, mortgagees and successors

in the making or performing of any Alterations. 
 (b) Landlord shall indemnify, defend and hold harmless Tenant, its
employees, shareholders, agents and contractors, from and against all loss, liability, damages, claims, liabilities and costs (including, but not limited to attorney” fees) incurred in connection with or arising from (I) the negligence or
willful misconduct of Landlord, its agents, employees or contractors, (ii) Landlord’s operation and management of the Premises; (iii) latent defects in the Premises, (iv) any breach of Landlord’s obligation sunder this
Lease; and (v) the presence of any hazardous materials in the or contamination in the Building or on the Real Property resulting from Landlord’s acts or omissions. This section 18.2 shall survive termination or expiration of this Lease.

required by this Article 18.3 of the Lease. (C) WAIVER OF SUBROGATION. Anything in this Lease to the contrary notwithstanding, Landlord and Tenant each waive any and all rights of recovery, claims, actions or causes of action, against the
other, its agents, officers, or employees, for any loss or damage that may occur to the Premises or Building, regardless of cause or origin, including the negligence of Landlord or Tenant, their agents, officers or employees, if:
(i) any such loss or damage is covered by insurance benefiting the party suffering such loss or damage or (ii) is required to be covered by insurance pursuant to this Lease. (D) INDEMNITY. Unless due to Landlord’s negligence or
willful misconduct, Tenant shall protect, indemnify, defend and hold Landlord harmless from any and all cost, loss, damage, liability or expense arising out of or connected with injury or damage, including death, to persons or property occurring on
the Premises, or arising out of any act or omission of Tenant, its agents, officers, employees or invitees. Unless due to Tenant’s negligence or willful misconduct, Landlord shall protect, indemnify, defend and hold Tenant harmless from any and
all cost, loss, damage, liability or expense arising out of, or connected with injury or damage, including death, to persons or property occurring in or around the Building, common areas or parking lot, or arising out of any act or omission of
Landlord, its agents, officers, employees or invitees. 
 18.4 Delivery of Policies. Tenant shall deliver policies of all
required insurance, or certificates thereof, to Landlord on or before the Rent Commencement Date, and thereafter at least thirty (30) days before the expiration dates of expiring policies. In the event Tenant shall fail to procure such
insurance, or to deliver such policies or certificates, Landlord may, at its option, procure same for the account of Tenant, and the cost thereof shall be paid to Landlord as Additional Rent within five (5) days after delivery to Tenant of
bills therefor. Landlord shall give Tenant opportunity to cure. Tenant’s compliance with the provisions of this Section 18.4 shall in no way limit Tenant’s liability under any of the other provisions of this Section. 

18.5 Landlord Not Liable. Landlord shall not be responsible for or liable to Tenant for any loss or damage that may be occasioned
by or through the acts or omissions of persons occupying adjoining premises or any part of the premises adjacent to or connection with the Premises or any part of the Building or of third parties either legally or illegally within the Premises or

than Basic Rent) accruing from Tenant to Landlord pursuant to any provision of this Lease, whether prior to or after the Rent Commencement Date, may, at Landlord’s option, be deemed Additional Rent. Tenant’s obligations under this 18.6
shall survive the expiration or earlier termination of the Term. 
 19. Access to Premises 

19.1 Landlord’s Right to Enter. Landlord reserves and shall have the right with prior notice, excepting emergencies, to enter
the Premises at all reasonable times to inspect same, to show the Premises to prospective purchasers, mortgagees or tenants, to post notices of nonresponsibility, and to alter, improve or repair the Premises, adjacent premises and any other portion
of the Building or any systems serving any of the same, without abatement of Basic Rent or Additional Rent, and may for that purpose erect, use and maintain scaffolding, pipes, conduits and other necessary structures in and through the Premises
where reasonably required by the character of the work to be performed; provided that the entrance to the Premises shall not be blocked thereby. Landlord shall use best efforts to minimize disruption to Tenant, and where reasonable, shall perform
work “after hours.” Landlord and its agents shall also have unrestricted access to the Premises at any time in the event of an emergency, without abatement of Basic Rent or Additional Rent. Tenant hereby waives any claim for damages for
any injury or inconvenience to or interference with Tenant’s business, any loss of occupancy or quiet enjoyment of the Premises or any other loss occasioned thereby. For each of the aforesaid purposes, Landlord shall at all times have and
retain a key with which to unlock all of the doors in, upon and about the Premises, excluding Tenant’s vaults and safes, or special security areas (designated as such by Tenant in advance), and Landlord shall have the right to use any and all
means that Landlord may deem necessary or proper to open said doors in an emergency, in order to obtain entry to any portion of the Premises, and any entry to the Premises or portions thereof obtained by Landlord by any of said means, or otherwise,
shall not under any circumstances be construed or deemed to be a forcible or unlawful entry into, or a detainer of, the Premises, or an eviction, actual or constructive, of Tenant from the Premises or any portion thereof. Landlord shall also have
the right at any time, without same constituting an actual or constructive eviction and without incurring any liability to Tenant therefor, to change the arrangement and/or location of entrances or passageways, doors and doorways, and corridors,
elevators, stairs, toilets and other public parts of the Building. Landlord will not show prospective tenants the Premises earlier than six (6) months prior to the lease termination date. Notwithstanding the foregoing, any work done by Landlord
shall not interfere with Tenant’s business and shall not prevent access to the Premises by Tenant or Tenant’s patients. 
 20. Waiver; Release 
 20.1 No Waiver. No failure by Landlord to
insist upon the strict performance of any obligation of Tenant under this Lease or to exercise any right, power or remedy consequent upon a breach thereof, no acceptance of full or partial Basic rent or Additional Rent during the continuance of any
such breach, and no acceptance of the keys to or possession of the Premises prior to the termination of the Term by any employee of Landlord shall constitute a waiver of 

  
 - 10 -









 
any such breach or of such term, covenant or condition or operate as a surrender of this Lease. No payment by Tenant or receipt by Landlord or a lesser amount than the aggregate of all Basic Rent
and Additional Rent then due under this Lease shall be deemed to be other than on account of the first items of such Basic Rent and Additional Rent then accruing or becoming due, unless Landlord elects otherwise; and no endorsement or statement on
any check and no letter accompanying any check or other payment of Basic Rent or Additional Rent in any such lesser amount and no acceptance of any such check or other such payment by Landlord shall constitute an accord and satisfaction, and
Landlord may accept such check or payment without prejudice to Landlord’s right to recover the balance of such Basic Rent or Additional Rent or to pursue any other legal remedy. 

20.2 Modifications in Writing. Neither this Lease nor any term or provision hereof may be changed, waived, discharged or
terminated orally, and no breach thereof shall be waived, altered or modified, except by a written instrument signed by the party against which the enforcement of the change, waiver, discharge or termination is sought. No waiver of any breach shall
affect or alter this Lease, but each and every term, covenant and condition of this Lease shall continue in full force and effect with respect to any other then existing or subsequent breach thereof. 

21. Tenant’s Certificates Tenant, at any time and from time to time not to exceed twice annually upon not less than fifteen
(15) days’ prior written notice from Landlord, will execute, acknowledge and deliver to Landlord and, at Landlord’s request, to any prospective purchaser, or mortgagee of any part of the Building and Real Property, a certificate of
Tenant stating: (a) that Tenant has accepted the Premises (or, if Tenant has not done so, that Tenant has not accepted the Premises and specifying the reasons therefor), (b) the Commencement and Term Expiration Dates of this Lease,
(c) that this Lease is unmodified and in full force and effect (or, if there have been modifications, that same is in full force and effect as modified and stating the modifications), (d) whether or not there are then existing any defenses
against the enforcement of any of the obligations of Tenant under this Lease (and, if so, specifying same), (f) the dates, if any, to which the Basic Rent and Additional Rent and other charges under this Lease have been paid. It is intended
that any such certificate of Tenant delivered pursuant to this Section 21 may be relied upon by Landlord and any prospective purchaser, ground or underlying lessor or mortgagee of any part of the Real Property. 

22. Rules and Regulations Tenant, its agents, employees, invitees, licensees, customers, clients and guests shall at all times
faithfully observe and comply with the rules and regulations attached hereto as Exhibit C, and such other rules and regulations as may be promulgated from time to time by Landlord, and all modifications thereof and additions thereto, from
time to time, put into effect by Landlord. Landlord shall not be responsible for the nonperformance by any other tenant or occupant of the Building of any said rules and regulations. In the event of an express and direct conflict between the terms,
covenants, agreements and conditions of this Lease and the terms, covenants, agreements and conditions of such rules and regulations, as modified and amended from time to time by Landlord, this Lease shall control. All rules shall be applied
uniformly and without discrimination. 
 23. Tax on Tenant’s Personal Property Prior to delinquency, Tenant shall
pay all taxes levied or assessed upon Tenant’s equipment, furniture, fixtures and other personal property located in or about the Premises. If the assessed value of Landlord’s property is increased by the inclusion therein of a value
placed upon Tenant’s equipment, furniture, fixtures or other personal property, Tenant shall pay to Landlord, upon demand, the taxes so levied against Landlord, or the portion thereof resulting from said increase in assessment. 

24. Authority The persons executing this Lease on behalf of Tenant hereby covenant and warrant that Tenant is a duly authorized
and existing entity, that Tenant has and is qualified to do business in the Commonwealth of Virginia, that Tenant has full right and authority to enter into this Lease, and each person signing on behalf of Tenant is authorized to do so. Upon
Landlord’s request, Tenant shall provide Landlord with evidence reasonably satisfactory to Landlord confirming the foregoing covenants and warranties. Landlord warrants that it has fee simple ownership of the Building and the Premises, subject
to encumbrances of record. Landlord covenants that it has full right, power and authority to enter into this Lease. 
 25.
Signage Tenant shall be allowed signage rights in accordance with applicable local zoning ordinances and the Covenants, provided, however, that no sign, advertising or notice shall be inscribed, affixed or displayed on any part of the outside
or inside or the Building, unless such sign specifications and location are approved in writing in advance by Landlord not to be unreasonably withheld or delayed. If any sign, advertisement or notice is improperly exhibited Landlord shall have the
right to remove the same, and Tenant shall be liable for any and all expenses incurred by Landlord in such removal. Landlord shall have the right to prohibit any advertising by Tenant, which, in Landlord’s opinion, tends to impair the
reputation of the Building or its desirability as a high quality retail, commercial or office building. Tenant shall be allowed to install signage on the glass entry door for the Premises and a directional sign at the entrance to the building
parking lot indicating the location of Tenant’s Premises. Exact location and design of signage shall be subject to all laws and ordinances of the Town of Leesburg and prior approval of Landlord which shall not be unreasonably withheld or
delayed. 
 26. Parking Tenant shall have the right to use the parking facilities of the Building. Tenants use of such
facilities shall be in common with other tenants or occupants of the Building and their respective licensees and permitees and Tenant shall not be entitled to assigned parking spaces. In any event, Tenant’s use of the parking facilities shall
be in accordance with the rules and regulations of Landlord or any perator of such facilities in effect from time to time. The parking facilities shall be lighted during evening hours. Tenant shall be allowed the use of three (3) parking spaces
per 1,000 SF leased. Landlord has the right to restrict the use of the parking area to this number. Tenants parking ratio shall remain consistent in the event of expansion within the park.

underlying lease referred to herein. 
 27.12 No Reduction in Rent. Tenant covenants and agrees that no diminution of
light, air or view by any structure that may hereafter be erected (whether or not by Landlord) shall entitle Tenant to any reduction of Basic Rent or Additional Rent under this Lease, result in any liability of Landlord to Tenant, or in any other
way affect this Lease or Tenant’s obligations hereunder. 
 27.13 Holding Over by Tenant. Any holding over after the
Term Expiration Date or the termination of the Term if sooner with the consent of Landlord shall be construed to be a tenancy from month to month at a rental equal to one and one quarter (1.25) times the Basic Rent herein specified unless
Landlord shall specify a different rent in its sole discretion, together with an amount estimated by Landlord for the monthly Additional Rent payable under this Lease, and shall otherwise be on the terms and conditions herein specified so far as
applicable. Any holding over without Landlord’s consent shall constitute a default by Tenant and entitle Landlord to reenter the Premises as provided in Section 16 hereof. 

27.14 Broker; Indemnification Therefore. Landlord warrants that they have engaged Vaaler Real Estate Company,
Inc., (the “Landlord’s Broker”) and Tenant warrants that they have engaged Spaulding & Slye (Bob Shue, the “Tenant’s Broker”), respectively, as their exclusive brokers in connection with negotiating and
entering into the Lease and Landlord hereby agrees to pay the Broker(s) a commission under the terms of a separate agreement. Tenant and Landlord shall indemnify each other and hold each other harmless respectively from and against any and all
claims, demands, losses, liabilities, actions, judgments, costs and expenses (including reasonable attorneys’ fees) suffered or incurred by the other and arising out of any claims for commissions or other compensation alleged to be owing on
account of Tenant and Landlord, respectively, dealing with any other broker, agent or finder. The commission paid to the brokers shall be 2.5% of the gross lease rent for the first five years of the lease to Spaulding & Slye Colliers and
2.5% of the gross lease rent for the first five years of the lease to Vaaler Real Estate Company, Inc. In the event the Tenant is not in Default and elects the 3 year Renewal Option, at the commencement of the sixth (6th) lease year, Landlord shall pay a commission to the brokers
equal to 3% of the gross rent for years 6—8 of the lease to Spaulding & Slye Colliers and 2% of the gross rent for years 6—10 of the lease to Vaaler Real Estate Company, Inc. 

27.15 No Recordation of Lease by Tenant. Tenant will not record this Lease or any memorandum or short form hereof, but at the
request of Landlord, Tenant shall execute, acknowledge and deliver to Landlord in proper form for recordation a memorandum of this Lease, setting forth the terms and provisions hereof in summary form. 

27.16 No Merger of Estates. The fee title of Landlord and the leasehold estate of Tenant shall at all times be separate and apart,
and shall in no event be merged, notwithstanding the fact that this Lease or the leasehold estate created hereby, or any interest in either thereof, may be held directly or indirectly by or for the account of any person who shall own the fee estate
in the Premises or any portion thereof; and no such merger of estates shall occur by operation of law, or otherwise, unless and until all persons at the time having any interest in the fee estate and all persons having any interest in the Lease or
the leasehold estate, including any mortgagee or leasehold mortgagee, shall join in the execution of a written instrument affecting such merger of estates. 
 27.17 Security Deposit. Simultaneously with the execution of this Lease, Tenant shall deposit with Landlord cash or the cash equivalent equal to One Month’s Rent, as a security deposit for the
performance by Tenant of the provisions of this Lease. The Security Deposit shall be one (1) month Basic Rent. Such deposit shall be considered as security for the payment and performance by Tenant of all Tenant’s obligations, covenants,
conditions and agreements under this Lease. In the event of any default by Tenant hereunder, landlord shall have the right, but shall not be obligated to apply all or any portion of the deposit to cure such default, in which event Tenant shall be
obligated to promptly deposit with Landlord the amount necessary to restore the deposit to its original amount. If Tenant is not in default at the expiration of the Term, Landlord shall return the security deposit to Tenant plus simple interest
accrued at the then current passbook rate. 
 27.18 Right to Expand. Tenant shall have the First Right of Offer to lease
any adjacent space within the building. Options and times of space availability will be communicated when opportunity to expand is apparent.
