maintain the Premises in a clean and healthful condition, and materially comply with all laws, ordinances, orders, rules and regulations of any governmental entity with reference to the use, condition, configuration or occupancy of the Premises.
Tenant, within ten (10) days after the receipt thereof, shall provide Landlord with copies of any notices it receives with respect to a violation or alleged violation of any such laws, ordinances, orders, rules and regulations. Tenant, at its

 5. Base Rent. 
 A. Tenant covenants and agrees to pay to Landlord during the Lease Term, without any setoff or deduction, except as otherwise expressly provided herein (including, without limitation, the Improvement Cost
offset described below in Section 5.D.), the full amount of all Base Rent and Additional Rent due hereunder and the full amount of all such other sums of money as shall become due under this Lease (including, without limitation, any charges for
replacement of electric lamps and ballasts and any other services, goods or materials furnished by Landlord at Tenant’s request), all of which hereinafter may be collectively called “Rent.” The Rent for each calendar year or
portion thereof during the Lease Term, except as specifically offset herein, shall be due and payable in advance in monthly installments of the first day of each calendar month during the Lease Term and any extensions or renewals hereof, and Tenant
hereby agrees to pay such Rent to Landlord without demand. If the Lease Term commences on a day other than the first day of a month or 

  
 3 

 
terminates on a day other than the last day of a month, then the installments of Base Rent and Additional Rent for such month or months shall be prorated, based on the number of days in such
month. No payment by Tenant or receipt or acceptance by Landlord of a lesser amount than the correct installment of Rent due under this Lease shall be deemed to be other than a payment on account of the earliest Rent due hereunder, nor shall any
endorsement or statement on any check or any letter accompanying any check or payment be deemed an accord and satisfaction, and Landlord may accept such check or payment without prejudice to Landlord’s right to recover the balance or pursue any
other available remedy. The acceptance by Landlord of an installment of Rent on a date after the due date of such payment shall not be construed to be a waiver of Landlord’s right to declare a default for any other late payment. All amounts
received by Landlord from Tenant hereunder shall be applied first to the earliest accrued and unpaid Rent then outstanding. Tenant’s covenant to pay Rent shall be independent of every other covenant set forth in this Lease. 

B. To the extent allowed by law, all installments of Rent not paid when due shall bear interest at the Default Rate from the date due
until paid. In addition, if Tenant fails to pay any installment of Base Rent and Additional Rent or any other item of Rent when due and payable hereunder, a “Late Charge” equal to five percent (5%) of such unpaid amount will be
due and payable immediately by Tenant to Landlord. 
 C. The Additional Rent payable hereunder shall be adjusted from
time-to-time in accordance with the provisions of Exhibit C attached hereto and incorporated herein for all purposes. 
 D. Landlord acknowledges and agrees that, in order to prepare the Premises for the Permitted Use, Tenant will be required to complete the Improvements (as defined below). Within thirty (30) days of
the completion of the Improvements, Tenant will provide Landlord with an invoice of the final Improvement Cost (as defined below) for such Improvements. The anticipated Improvement Cost is five hundred thousand dollars ($500,000.00). Notwithstanding
anything to the contrary in this Agreement, Landlord, in return for the increase in value to the Premises resulting from the Improvements, shall reimburse Tenant for the Improvement Cost, as adjusted herein (the “Improvement
Balance”). Landlord agrees to pay, and Tenant agrees to accept payment of, such Improvement Balance by offsetting Tenant’s monthly Rent obligation hereunder against such Improvement Balance. Beginning on the first month during the
Lease Term, Landlord will deduct the Rent owed to Landlord by Tenant under this Agreement from the Improvement Balance and will accept such deduction as payment in full for such monthly Rent obligation, and the Improvement Balance will be adjusted
accordingly. Such Rent offset shall continue until the Improvement Balance has been paid in full, at which time, Tenant will be required to pay Rent in accordance with the terms herein. For purposes of this Agreement, “Improvements”
mean any addition, alteration, construction, finish or improvement to the Premises; any attachment (including, but not limited to, attachment through the use of drilling) of a permanent fixture, permanent furniture, or permanent equipment; and
includes, but is not limited to, completing the interior walls, partitioning(s), ceiling work, utilities, floor covering, painting, finish work, restroom facilities, and any other thing necessary for Tenant to obtain a certificate of occupancy for
the Premises and operate the same for the Permitted Use in a style and manner customary for a business of its size and industry, as determined in Tenant’s sole discretion . For purposes of this Agreement, “Improvement Cost”

electric lines, feeders, risers, wiring, and any other machinery within the Premises, provided such access otherwise complies with Section 12. below). Except to the extent caused by its negligence or willful acts or omissions, Landlord shall in
no way be liable or responsible for any loss, damage, or expense that Tenant may sustain or incur by reason of any change, failure, interference, disruption, or defect in the supply or character of the electric energy furnished to the Premises, or
if the quantity or character of the electric energy supplied by the Electric Service Provider is no longer available or suitable for Tenant’s requirements, and no such change, failure, defect, unavailability, or unsuitability shall constitute
an actual or constructive eviction, in whole or in part, or entitle Tenant to any abatement or diminution of rent, or relieve Tenant from any of its obligations under the Lease. 

  
 7 

 B. Tenant’s use of electrical services furnished by Landlord shall not exceed in
voltage, rated capacity, or overall load that which is reasonably standard for the Building and/or for other similarly situated office buildings within the surrounding community. In the event Tenant shall request that it be allowed to consume
electrical services in excess of such standards, Landlord shall consent to such usage, but Landlord, in its reasonable discretion, may require reasonable conditions on such consent (including the installation of utility service upgrades, submeters,
air handlers or cooling units). All such additional usage (to the extent permitted by law), installation, maintenance and preventative maintenance by a qualified vendor thereof shall be paid for by Tenant as Additional Rent. Landlord, at any time
during the Lease Term, shall have the right to separately meter electrical usage for the Premises or to measure electrical usage by survey or any other method that Landlord, in its reasonable judgment, deems appropriate.

relocation) or insurers, or to clean or make repairs, alterations, or additions thereto, including any work that Landlord deems necessary for the safety, protection or preservation of the Building or any occupants thereof, or to facilitate repairs,
alterations or additions to the Building or any other tenant’s premises. Except for any entry by Landlord in an emergency situation or to provide normal cleaning and janitorial service, Landlord shall provide Tenant with reasonable prior
notice, which at a minimum shall provide Tenant sufficient time to protect patient confidentiality and preserve patient’s privacy, of any entry into the Premises, which notice may be given verbally. Landlord shall have the right to temporarily
close the Premises or the Building to perform repairs, alterations or additions in the Premises or the Building, provided that Landlord shall use best efforts to perform all such work on weekends and after Normal Business Hours. Notwithstanding the
foregoing, Landlord shall not unreasonably interfere with Tenant’s operations during any period of re-entry under this Section 12. 

13. Assignment and Subletting 
 A. Except in connection with a Permitted Transfer (defined in Section 13.E. below), Tenant shall not assign, sublease, transfer or encumber any interest in this Lease or allow any third party to use
any portion of the Premises (collectively or individually, a “Transfer”) without the prior written consent of Landlord, which consent shall not be unreasonably withheld. Without limitation, it is agreed that Landlord’s consent
shall not be considered unreasonably withheld if: (1) the proposed transferee’s financial condition does not meet the criteria Landlord uses to select Building tenants having similar leasehold obligations; (2) the proposed
transferee’s business is not suitable for the Building considering the business of the other tenants and the Building’s prestige, or would result in a violation of another tenant’s rights; (3) the proposed transferee is a
governmental agency or occupant of the Building; (4) Tenant is in default beyond any applicable notice and cure period; or (5) any portion of the Building or the Premises would likely become subject to additional or different laws as a
consequence of the proposed Transfer. Any attempted Transfer in violation of this Section 13, shall, exercisable in Landlord’s sole and absolute discretion, be voidable. Consent by Landlord to one or more Transfer(s) shall not operate as a
waiver of Landlord’s rights to approve any subsequent Transfer(s). In no event shall any Transfer or Permitted Transfer release or relieve Tenant from any obligation under this Lease or any liability hereunder. 

  
 8 

 B. If Tenant requests Landlord’s consent to a Transfer, Tenant shall submit to Landlord
financial statements for the proposed transferee, a complete copy of the proposed assignment, sublease and other information as Landlord may reasonably request. Landlord shall within thirty (30) days after Landlord’s receipt of the
required information and documentation either: (1) consent or reasonably refuse consent to the Transfer in writing; (2) in the event of a proposed assignment of this Lease or a proposed sublease of the entire Premises for the entire
remaining term of this Lease, terminate this Lease effective the first to occur of ninety (90) days following written notice of such termination or the date that the proposed Transfer would have come into effect. If Landlord shall fail to
notify Tenant in writing of its decision within such thirty (30) days period after the later of the date Landlord is notified in writing of the proposed Transfer or the date Landlord has received all required information concerning the proposed
transferee and the proposed Transfer, Landlord shall be deemed to have refused to consent to such Transfer, and to have elected to keep this Lease in full force and effect. 
 C. [Intentionally Left Blank] 
 D. Except as provided below with respect to a
Permitted Transfer, if Tenant is a corporation, limited liability company, partnership or similar entity, and the entity which owns or controls a majority of the voting shares/rights at the time changes for any reason (including but not limited to a
merger, consolidation or reorganization), such change of ownership or control shall constitute a Transfer. The foregoing shall not apply so long as Tenant is an entity whose outstanding stock is listed on a nationally recognized security exchange,
or if at least eighty percent (80%) of its voting stock is owned by another entity, the voting stock of which is so listed. 

E. Tenant may assign its entire interest under this Lease or sublet the Premises to any entity controlling or controlled by or under
common control with Tenant or to any successor to Tenant by purchase, merger, consolidation or reorganization (hereinafter, collectively, referred to as “Permitted Transfer”) without the consent of Landlord, provided:
(1) Tenant is not in default under this Lease; (2) if such proposed transferee is a successor to Tenant by purchase, said proposed transferee shall acquire all or substantially all of the stock or assets of Tenant’s business or, if
such proposed transferee shall acquire all or substantially all of the stock or assets of Tenant’s business or, if such proposed transferee is a successor to Tenant by merger, consolidation or reorganization, the continuing or surviving
corporation shall own all or substantially all of the assets of Tenant; (3) such proposed transferee shall have a net worth which is at least equal to the greater of Tenant’s net worth at the date of this Lease or Tenant’s net worth
as of the day prior to the proposed purchase, merger, consolidation or reorganization as evidenced to Landlord’s reasonable satisfaction; (4) such proposed transferee operates the business in the Premises for the Permitted Use and no other
purpose; and (5) Tenant shall give Landlord written notice at least thirty (30) days prior to the effective date of the proposed purchase, merger, consolidation or reorganization. 

F. Tenant agrees that in the event Landlord withholds its consent to any Transfer contrary to the provisions of this Section 13,
Tenant’s sole remedy shall be to seek an injunction in equity or compel performance by Landlord to give its consent and Tenant expressly waives any right to damages in the event of such withholding by Landlord of its consent. 

14. Mechanic’s Liens. Tenant will not permit any mechanic’s liens or other liens to be placed upon the Premises, the Building, or
the Property and nothing in this Lease shall be deemed or construed in any way as constituting the consent or request of Landlord, express or implied, by inference or otherwise, to any person for the performance of any labor or the furnishing of any
materials to the Premises, the Building, or the Property or any part thereof, nor as giving Tenant any right, power, or authority to contract for or permit the rendering of any services or the furnishing of any materials that would give rise to any
mechanic’s or other liens against the Premises, the Building, or the Property. In the event any such lien is attached to the Premises, the Building, or the Property, then, in addition to any other right or remedy of Landlord, Landlord may, but
shall not be obligated to, discharge the same. Any amount paid by Landlord for any of the aforesaid purposes including, but not limited to, reasonable attorneys’ fees, shall be paid by Tenant to Landlord promptly on demand as Additional Rent.
Tenant shall within ten (10) days of receiving such notice of lien or claim (a) have such lien or claim released or (b) deliver to Landlord a bond in form, content, amount and issued by surety, satisfactory to Landlord, indemnifying,
protecting, defending and holding harmless the Indemnities against all costs and liabilities resulting from such lien or claim and the foreclosure or attempted foreclosure thereof. Tenant’s failure to comply with the provisions of the foregoing
sentence shall be deemed an Event of Default under Section 22. hereof entitling Landlord to exercise all of its remedies therefor without the requirement of any additional notice or cure period.

 15. Insurance. 
 A. Landlord shall maintain such insurance on the Building and the Premises (other than on Tenant’s Property or on any additional improvements constructed in the Premises by Tenant), and such
liability insurance in such amounts as Landlord elects. The cost of such insurance shall be included as a part of the Basic Costs, and payments for losses thereunder shall be made solely to Landlord or the mortgagees of Landlord as their interests
shall appear. 
 B. Tenant shall maintain at its expense, (1) in an amount equal to full replacement cost, special form
(formerly known as all risk) property insurance on all of its personal property, including removable trade fixtures and leasehold and tenant improvements, and Tenant’s Property located in the Premises and in such additional amounts as are
required to meet Tenant’s obligations pursuant to Section 18 hereof and with deductibles in an amount reasonably satisfactory to Landlord, and (ii) a policy or policies of commercial general liability insurance (including
endorsement or separate policy for owned or non-owned automobile liability) with respect to its activities in the Building and on the Property, with the premiums thereon fully paid on or before the due date, in an amount of not less than $1,000,000
per occurrence per person coverage for bodily injury, property damage, personal injury or combination thereof (the term “personal injury” as used herein means, without limitation, false arrest, detention or imprisonment, malicious
prosecution, wrongful entry, liable and slander), provided that if only single limit coverage is available it shall be for at least $1,000,000 per occurrence with an umbrella policy of at least $5,000,000 combined single limit per occurrence.
Tenant’s insurance policies shall name Landlord and Building Manager as additional insureds. Prior to Tenant’s taking possession of the Premises, Tenant shall furnish evidence satisfactory to Landlord of the maintenance and timely renewal
of such insurance 
 C. The insurance requirements set forth in this Section 15 are independent of the waiver,
indemnification, and other obligations under this Lease and will not be construed or interpreted in any way to restrict, limit or modify the waiver, indemnification and other obligations or to in any way limit any party’s liability under this
Lease. In addition to the requirements set forth in Sections 15 and 16, the insurance required of Tenant under this Lease must be issued by an insurance company admitted to engage in the business of insurance in the state in which the Building is
located; be primary insurance for all claims under it and provide that any insurance carried by Landlord and Landlord’s lenders is strictly excess, secondary and noncontributing with any insurance carried by Tenant; and provide that insurance
may not be cancelled, nonrenewed or the subject of material change in coverage of available limits of coverage, except upon thirty (30) days prior written notice to Landlord and Landlord’s lenders. Upon Landlord’s request, Tenant will
deliver either a duplicate original or a legally enforceable certificate of insurance on all policies procured by Tenant in compliance with Tenant’s obligations under this Lease, to Landlord on or before the date Tenant first occupies any
portion of the Premises and upon the renewal of any policy. Tenant may comply with its insurance coverage requirements through a blanket policy, provided Tenant, at Tenant’s sole expense, procures a “per location” endorsement, or
equivalent reasonably acceptable to Landlord, so that the general aggregate and other limits apply separately and specifically to the Premises. 
 D. If Tenant’s business operations, conduct or use of the Premises or any other part of the Property causes an increase in the premium for any insurance policy carried by Landlord, Tenant will,
within ten (10) days after receipt of notice from Landlord, reimburse Landlord for the entire increase. 
 E. Neither
Landlord nor Tenant shall be liable (by way of subrogation or otherwise) to the other party (or to any insurance company insuring the other party) for any personal injury or loss or damage to any of the property of Landlord or Tenant, as the case
may be, with respect to their respective property, the Building, the Property or the Premises or any addition or improvements thereto, or any contents therein, to the extent covered by insurance carried or required to be carried by a party hereto
even though such loss might have been occasioned by the negligence or willful acts or omissions of the Landlord or Tenant or their respective employees, agents, contractors or invitees. For the purpose of the foregoing waiver, the amount of any
deductible applicable to any loss or damage shall be deemed covered by, and recoverable by the insured under the insurance policy to which such deductible relates. In the event that Tenant is permitted to and self-insures any risk for which
insurance is required to be carried under this Lease, or if Tenant fails to carry any insurance required to be carried by Tenant pursuant to this Lease, then all loss or damage to Tenant, its leasehold interest, its business, its property, the
Premises or any additions or improvements thereto or contents thereof shall be deemed covered by and recoverable by Tenant under valid and collectible policies of insurance.

 16. Indemnity. To the extent not expressly prohibited by law, neither Landlord nor Building
Manager nor any of their respective officers, directors, employees, members, managers, or agents shall be liable to Tenant, or to Tenant’s agents, servants, employees, customers, licensees, or invitees for any injury to person or damage to
property caused by any act, omission, or neglect of Tenant, its agents, servants, employees, customers, invitees, licensees or by any other person entering the Building or upon the Property under the invitation of Tenant or arising out of the use of
the Property, Building or Premises by Tenant and the conduct of its business or out of a default by Tenant in the performance of its obligations hereunder. Tenant hereby indemnifies and holds Landlord and Building Manager and their respective
officers, directors, employees, members, managers and agents (“Indemnitees”), harmless from all liability arising from any third party claim for any property damage, or bodily injury or death of, or personal injury to, a person in
or on the Premises, or at any other place, including the Property or the Building, resulting from or relating to Tenant’s use or occupancy of the Premises. This indemnity shall be enforceable to the full extent whether or not such liability and
claims are the result of the sole, joint or concurrent acts, negligent or intentional, or otherwise, of Tenant, or its employees, agents, servants, customers, invitees or licensees. Such indemnification shall not be applicable to the extent the
liability and/or the third party claim arises as a result of an act or failure to act by the Indemnitees. Notwithstanding the terms of this Lease to the contrary, the terms of this Section shall survive the expiration or earlier termination of this
Lease. 
 17. Damages from Certain Causes. To the extent not expressly prohibited by law and except as caused
by Landlord’s negligence or willful misconduct or Landlord’s failure to make repairs required to be made pursuant to other provisions of this Lease after the expiration of a reasonable time after written notice to Landlord of the need for
such repairs, Landlord shall not be liable to Tenant or Tenant’s employees, contractors, agents, invitees or customers, for any injury to person or damage to property sustained by Tenant or any such party or any other person claiming through
Tenant resulting from any accident or occurrence in the Premises or any other portion of the Building caused by the Premises or any other portion of the Building becoming out of repair or by defect in or failure of equipment, pipes, or wiring, or by
broken glass, or by the backing up of drains, or by gas, water, steam, electricity, or oil leaking, escaping or flowing into the Premises , nor shall Landlord be liable to Tenant for any loss or damage that may be occasioned by or through the acts
or omissions of other tenants of the Building or of any other persons whomsoever, including, but not limited to riot, strike, insurrection, war, court order, requisition, order of any governmental body or authority, acts of God, fire or theft.

 18. Casualty Damage. If the Premises or any part thereof shall be damaged by fire or other casualty, Tenant shall give
prompt written notice thereof to Landlord. In case the Building shall be so damaged that substantial alteration or reconstruction of the Building shall, in Landlord’s sole opinion, be required (whether or not the Premises shall have been
damaged by such casualty) or in the event there is less than two (2) years of the Lease Term remaining or in the event Landlord’s mortgagee should require that the insurance proceeds payable as a result of a casualty be applied to the
payment of the mortgage debt or in the event of any material uninsured loss to the Building, Landlord may, at its option, terminate this Lease by notifying Tenant in writing of such termination within ninety (90) days after the date of such
casualty. If Landlord does not thus elect to terminate this Lease, Landlord shall commence and proceed with reasonable diligence to restore the Building, and the improvements located within the Premises, if any, for which Landlord had financial
responsibility pursuant to the Work Letter Agreement attached hereto as Exhibit D (except that Landlord shall not be responsible for delays not within the control of Landlord) to substantially the same condition in which it was immediately
prior to the happening of the casualty. When the repairs described in the preceding two sentences have been completed by Landlord, Tenant shall complete the restoration of all improvements, including furniture, fixtures and equipment, which are
necessary to permit Tenant’s reoccupancy of the Premises. Except as set forth above, all cost and expense of reconstructing the Premises shall be borne by Tenant. Landlord shall not be liable for any inconvenience or annoyance to Tenant or
injury to the business of Tenant resulting in any way from such damage or the repair thereof, except that, subject to the provisions of the next sentence, Landlord shall allow Tenant a fair diminution of Rent during the time and to the extent the
Premises are unfit for occupancy. If the Premises or any other portion of the Property is damaged by fire or other casualty resulting from the fault or negligence of Tenant or any of Tenant’s agents, employees, or invitees, the rent hereunder
shall not be diminished during the repair of such damage and Tenant shall be liable to Landlord for the cost of the repair and restoration of the Premises caused thereby to the extent such cost and expense is not covered by insurance proceeds.

  
 11 

 19. Condemnation. If the whole or any substantial part of the Premises or if the Building or
any portion thereof which would leave the remainder of the Building unsuitable for use as an office building comparable to its use on the Commencement Date, or if the land on which the Building is located or any material portion thereof, shall be
taken or condemned for any public or quasi-public use under governmental law, ordinance or regulation, or by right of eminent domain, or by private purchase in lieu thereof, then Landlord may, at its option, terminate this Lease and the rent shall
be abated during the unexpired portion of this Lease, effective when the physical taking of said Premises or said portion of the Building or land shall occur. In the event this Lease is not terminated, the rent for any portion of the Premises so
taken or condemned shall be abated during the unexpired term of this Lease effective when the physical taking of said portion of the Premises shall occur. All compensation awarded for any such taking or condemnation, or sale proceeds in lieu
thereof, shall be the property of Landlord, and Tenant shall have no claim thereto, the same being hereby expressly waived by Tenant, except for any portions of such award or proceeds which are specifically allocated by the condemning or purchasing
party for the taking of or damage to trade fixtures of Tenant, which Tenant specifically reserves to itself. 
 20. Hazardous
Substances. 
 A. Tenant hereby represents and covenants to Landlord the following: No toxic or hazardous substances
or wastes, pollutants or contaminants (including, without limitation, asbestos, urea formaldehyde, the group of organic compounds known as polychlorinated biphenyls, petroleum products including gasoline, fuel oil, crude oil and various constituents

treatment, storage or disposal facility within the meaning of or otherwise bring the Property within the ambit of the Resource Conservation and Recovery Act of 1976 (“RCRA”), 42 U.S.C. 5901 et. seq., or any similar state law
or local ordinance, (ii) a release or threatened release of toxic or hazardous wastes or substances, pollutants or contaminants, from the Property or any part thereof within the meaning of, or otherwise result in liability in connection with
the Property within the ambit of CERCLA, or any similar state law or local ordinance, or (iii) the discharge of pollutants or effluents into any water source or system, the dredging or filling of any waters, or the discharge into the air of any
emissions, that would require a permit under the Federal Water Pollution Control Act, 33 U.S.C. 1251 et. seq., or the Clean Air Act, 42 U.S.C. 7401 et. seq., or any similar state law or local ordinance. 

B. Tenant expressly waives, to the extent allowed by law, any claims under federal, state or other law that Tenant might otherwise have
against Landlord relating to the condition of such Property or the Premises or the Leasehold Improvements or personal property located thereon or the presence in or contamination of the Property or the Premises by hazardous materials. Tenant agrees
to indemnify and hold Indemnitees (as defined in Section 16) harmless from and against and to reimburse Indemnitees with respect to, any and all claims, demands, causes of action, loss, damage, liabilities, costs and expenses (including
attorneys’ fees and court costs) of any and every kind or character, known or unknown, fixed or contingent, asserted against or incurred by Landlord at any time and from time-to-time by reason of or arising out of the breach of any
representation or covenant contained in Section 20.A above. 

  
 12 

 C. Tenant shall immediately notify Landlord in writing of any release or threatened release
of toxic or hazardous wastes or substances, pollutants or contaminants of which Tenant has knowledge whether or not the release is in quantities that would require under law the reporting of such release to a governmental or regulatory agency.

Act (Public Law (July 26, 1990) (“ADA”) and such other current acts or other subsequent acts, (whether federal or state) addressing like issues, as are enacted or amended, to the extent the ADA and such other acts are applicable to

such compliance

within such thirty-day period, such default shall be deemed to have been cured if Tenant commences such performance within said thirty-day period and thereafter diligently undertakes to complete the same, and in fact, completes same within sixty
(60) days after notice.

may be pursued successively or cumulatively as Landlord may elect: 
  

	 	(1)	Landlord may re-enter the Premises and cure any default of Tenant, in which event Tenant shall, upon demand, reimburse Landlord as Additional Rent for any cost and

C. [Intentionally Left Blank] 
 D. If this Lease is terminated by Landlord pursuant to Section 23.A.(2), Landlord shall be entitled to recover from Tenant all Rent accrued and unpaid for the period up to and including such
termination date, as well as all other additional sums payable by Tenant, or for which Tenant is liable or for which Tenant has agreed to indemnify Landlord under any of the provisions of this Lease, which may be then owing and unpaid, and all costs
and expenses, including without limitation court costs and attorneys’ fees incurred by Landlord in the enforcement of its rights and remedies hereunder, and, in addition, Landlord shall be entitled to recover as damages for loss of the bargain
and not as a penalty (i) the unamortized portion of any concessions offered by Landlord to Tenant in connection with this Lease, including without limitation Landlord’s contribution to the cost of tenant improvements and alterations, if
any, installed by either Landlord or Tenant pursuant to this Lease or any work letter in connection with this Lease, (ii) the aggregate sum which at the time of such termination represents the excess, if any, of the present value of the
aggregate rents which would have been payable in the six (6) months after the termination date had this Lease not been terminated or the remainder of the Term, whichever is greater, including, without limitation, Base Rent at the annual rate or
respective annual rates provided for in this Lease and the amount projected by Landlord to represent Additional Rent, over the then present value of the then aggregate fair rent value of the Premises for the same time period, such present worth to
be computed in each case on the basis of a six percent (6%) per annum discount from the respective dates upon which such Rents would have been payable hereunder had this Lease not been terminated, and (iii) any damages in addition thereto,

E. Landlord shall use commercially reasonable efforts to mitigate any damages resulting from an Event of Default by Tenant under
this Lease. Landlord’s obligation to mitigate damages after an Event of Default by Tenant under this Lease shall be satisfied in full if Landlord undertakes to lease the Premises to another tenant (a “Substitute Tenant”)
in accordance with the following criteria: 
  

	 	(1)	Landlord shall have no obligations to solicit or entertain negotiations with any other prospective tenants for the Premises until Landlord obtains full and complete
possession of the Premises including, without limitation, the final and unappealable legal right to relet the Premises free of any claim of Tenant; 

  

	 	(2)	Landlord shall not be obligated to lease or show the Premises, on a priority basis, offer the Premises to a prospective tenant when other premises in the Building
suitable for that prospective tenant’s use are (or soon will be) available; 

  

	 	(3)	Landlord shall not be obligated to lease the Premises to a Substitute Tenant for a Rent less than the current fair market Rent then prevailing for similar uses in
comparable buildings in the same market area as the Building, nor shall Landlord be obligated to enter into a new lease under other terms and conditions that are unacceptable to Landlord under Landlord’s then current leasing policies for
comparable space in the Building; 

  
 15 

	 	(4)	Landlord shall not be obligated to enter into a lease with a Substitute Tenant whose use would: 

 

	 	(i)	violate any restriction, covenant, or requirement contained in the lease of another tenant of the Building; 

 

	 	(ii)	adversely affect the reputation of the Building; or 

  

	 	(iii)	be incompatible with the operation of the Building as an office building; 

  

	 	(5)	Landlord shall not be obligated to enter into a lease with any proposed Substitute Tenant which does not have, in Landlord’s reasonable opinion, sufficient
financial resources to operate the Premises in a first class manner; and 

  

	 	(6)	Landlord shall not be required to expend any amount of money to alter, remodel, or otherwise make the Premises suitable for use by a proposed Substitute Tenant unless:

  

	 	(i)	Tenant pays any such sum to Landlord in advance of Landlord’s execution of a lease with such tenant (which payment shall not be in lieu of any damages or other
sums to which Landlord may be entitled as a result of Tenant’s default under this Lease); or 

  

	 	(ii)	Landlord, in Landlord’s reasonable discretion, determines that any such expenditure is financially justified in connection with entering into any such substitute
lease. 

 F. All property of Tenant removed from the Premises by Landlord pursuant to any provision of this Lease
or applicable law may be handled, removed or stored by Landlord at the cost and expense of Tenant, and Landlord shall not be responsible in any event for the value, preservation or safekeeping thereof. Tenant shall pay Landlord for all expenses
incurred by Landlord with respect to such removal and storage so long as the same is in Landlord’s possession or under Landlord’s control. All such property not removed from the Premises or retaken from storage by Tenant within thirty
(30) days after the end of the Term or the termination of Tenant’s right to possession of the Premises, however terminated, at Landlord’s option, shall be conclusively deemed to have been conveyed by Tenant to Landlord as by bill of
sale without further payment or credit by Landlord to Tenant. 
 G. [Intentionally Left Blank] 

H. If Tenant is adjudged bankrupt, or a trustee in bankruptcy is appointed for Tenant, Landlord and Tenant, to the extent permitted by
law, agree to request that the trustee in bankruptcy determine within sixty (60) days thereafter whether to assume or to reject this Lease. 
 I. The receipt by Landlord of less than the full rent due shall not be construed to be other than a payment on account of rent then due, nor shall any statement on Tenant’s check or any letter
accompanying Tenant’s check be deemed an accord and satisfaction, and Landlord may accept such payment without prejudice to Landlord’s right to recover the balance of the rent due or to pursue any other remedies provided in this lease. The
acceptance by Landlord of rent hereunder shall not be construed to be a waiver of any breach by Tenant of any term, covenant or condition of this Lease. No act or omission by Landlord or its employees or agents during the term of this Lease shall be
deemed an acceptance of a surrender of the Premises, and no agreement to accept such a surrender shall be valid unless in writing and signed by Landlord. 
 J. In the event of any litigation between Tenant and Landlord to enforce any provision of this Lease or any right of either party hereto, the unsuccessful party to such litigation shall pay to the
successful party all costs and expenses, including reasonable attorney’s fees, incurred therein. Furthermore, if Landlord, without fault, is made a party to any litigation instituted by or against Tenant, Tenant shall indemnify Landlord
against, and protect, defend, and save it harmless from, all costs and expenses, including reasonable attorney’s fees, incurred by it in connection therewith. If Tenant, without fault, is made party to any litigation instituted by or against
Landlord, Landlord shall indemnify Tenant against, and protect, defend, and save it harmless from, all costs and expenses, including reasonable attorney’s fees, incurred by it in connection therewith. 

  
 16 

 24. No Waiver. Failure of Landlord to declare any default immediately upon its occurrence, or
delay in taking any action in connection with an event of default, shall not constitute a waiver of such default, nor shall it constitute an estoppel against Landlord, but Landlord shall have the right to declare the default at any time and take
such action as is lawful or authorized under this Lease. Failure by Landlord to enforce its rights with respect to any one default shall not constitute a waiver of its rights with respect to any subsequent default. 

25. Peaceful Enjoyment. Tenant shall, and may peacefully have, hold, and enjoy the Premises, subject to the other terms hereof, provided
that Tenant pays the Rent and other sums herein recited to be paid by Tenant and timely performs all of Tenant’s covenants and agreements herein contained. This covenant and any and all other covenants of Landlord shall be binding upon Landlord
and its successors only with respect to breaches occurring during its or their respective periods of ownership of the Landlord’s interest hereunder. 
  

	26.	[Intentionally Left Blank] 

 27.
Holding Over. In the event of holding over by Tenant after expiration or other termination of this Lease or in the event Tenant continues to occupy the Premises after the termination of Tenant’s right of possession pursuant to
Section 23.A(3) hereof, occupancy of the Premises subsequent to such termination or expiration shall be that of a tenancy at sufferance and in no event for month-to-month or year-to-year. Tenant shall, throughout the entire holdover period, be
subject to all the terms and provisions of this Lease and shall pay for its use and occupancy an amount (on a per month basis without reduction for any partial months during any such holdover) equal to twice the sum (or 200%) of (a) the greater
of then current market rate, or (b) the Base Rent and Additional Rent which would have been applicable had the Lease Term continued through the period of such holding over by Tenant. No holding over by Tenant or payments of money by Tenant to
Landlord after the expiration of the Lease Term shall be construed to extend the Lease Term or prevent Landlord from recovery of immediate possession of the Premises by summary proceedings or otherwise unless Landlord has sent written notice to
Tenant that Landlord has elected to extend the Lease Term. In addition to the obligation to pay the amounts set forth above during any such holdover period, Tenant shall also be liable to Landlord for all damages, including, without limitation, any
consequential damages, which Landlord may suffer by reason of any holding over by Tenant and Tenant shall also indemnify Landlord against any and all claims made by any other tenant or prospective tenant against Landlord for delay by Landlord in
delivering possession of the Premises to such other tenant or prospective tenant. 
 28. Subordination to Mortgage/Estoppel
Certificate. Tenant accepts this Lease subject and subordinate to any mortgage, deed of trust or other lien presently existing or hereafter arising upon the Premises, or upon the Building and/or the Property and to any renewals,
modifications, refinancings and extensions thereof, but Tenant agrees that any such mortgagee shall have the right at any time to subordinate such mortgage, deed of trust or other lien to this Lease on such terms and subject to such conditions as
such mortgagee may deem appropriate in its discretion. The provisions of the foregoing sentence shall be self-operative and no further instrument of subordination shall be required. However, Landlord is hereby irrevocably vested with full power and
authority to subordinate this Lease to any mortgage, deed of trust or other lien now existing or hereafter placed upon the Premises, or the Building and/or the Property and Tenant agrees within ten (10) days after demand to execute such further
instruments subordinating this Lease or attorning to the holder of any such liens as Landlord may request. The terms of this Lease are subject to approval by the Landlord’s existing lender(s) and any lender(s) who, at the time of the execution
of this Lease, have committed or are considering committing to Landlord to make a loan secured by all or any portion of the Property, and such approval is a condition precedent to Landlord’s obligations hereunder. In the event that Tenant
should fail to execute any subordination or other agreement required by this Section promptly as requested, Tenant hereby irrevocably constitutes Landlord as its attorney-in-fact to execute such 

  
 17

B. As soon as is practical following the end calendar year during the Lease Term, Landlord shall furnish to Tenant a statement of Landlord’s actual
Basic Costs for the previous calendar year. If for any calendar year the Additional Rent collected for the prior year, as a result of Landlord’s estimate of Basic Costs, is in excess of Tenant’s Pro Rata Share of the amount by which Basic

 ADDITIONAL PROVISIONS 

This Exhibit is attached to and made a part of the Lease dated February 15th, 2012 by and between City Place, L.L.C., an Oklahoma limited
liability company (“Landlord”) and Graymark Healthcare Inc., an Oklahoma corporation (“Tenant”) for space in the Building located at 204 North Robinson Avenue, Oklahoma City, Oklahoma. 

Renewal Option: Provided that Tenant is not in default under any term or provision contained in this Lease and provided that Tenant has
continuously occupied the Premises for the Permitted Use during the Lease Term, Tenant (but not any sublessee) shall have the right and option (the “Renewal Option”) to renew this Lease, by written notice delivered to Landlord no earlier
than six (6) months and no later than nine (9) months prior to the expiration of the initial Lease Term, for an additional term (the “Renewal Term”) of sixty (60) months under the same terms, conditions and covenants
contained in the Lease, except that (a) no abatements or other concessions, if any, applicable to the initial Lease Term shall apply to the Renewal Term; (b) the Base Rent shall be equal to the market rate for comparable office space
located in the Building as of the end of the initial Lease Term as verified by Landlord, (c) Tenant shall have no option to renew this Lease beyond the expiration of the Renewal Term; and (d) all leasehold improvements within the Premises
shall be provided in their then existing condition (on an “As Is” basis) at the time the Renewal Term commences. 
 Failure by Tenant
to notify Landlord in writing of Tenant’s election to exercise the Renewal Option herein granted within the time limits set forth for such exercise shall constitute a waiver of such Renewal Option. In the event Tenant elects to exercise the
Renewal Option as set forth above, Landlord shall, within thirty (30) days thereafter, notify Tenant in writing of the proposed rental for the Renewal Term (the “Proposed Renewal Rental”). Tenant shall within thirty (30) days
following delivery of the Proposed Renewal Rental by Landlord notify Landlord in writing of the acceptance or rejection of the Proposed Renewal Rental. If Tenant accepts Landlord’s proposal, then the Proposed Renewal Rental shall be the rental
rate in effect during the Renewal Term. 
 Failure of Tenant to respond in writing during the aforementioned thirty (30) day period shall
be deemed an acceptance by Tenant of the Proposed Renewal Rental. Should Tenant reject Landlord’s Proposed Renewal Rental during such thirty (30) day period, then Landlord and Tenant shall negotiate during the thirty (30) day period
commencing upon Tenant’s rejection of Landlord’s Proposed Renewal Rental to determine the rental for the Renewal Term. In the event Landlord and Tenant are unable to agree to a rental for the Renewal Term during said thirty (30) day
period, then the Renewal Option shall terminate and be null and void and the Lease shall, pursuant to its terms and provisions, terminate at the end of the original Lease Term.
