 LEASE 
 This Lease Agreement (this “Lease”) is entered into as of November 27, 2006, between CRP HOLDINGS V, L.P., a Delaware limited partnership (“Landlord”),
and ENERGYTEC, INC., a Nevada corporation (“Tenant”). 
 1. Definitions and Basic Provisions.
The definitions and basic provisions set forth in the Basic Lease Information (the “Basic Lease Information”) executed by Landlord and Tenant contemporaneously herewith are incorporated herein by reference for all purposes.
Additionally, the following terms shall have the following meanings when used in this Lease: “Affiliate” means any person or entity which, directly or indirectly, through one or more intermediaries, controls, is controlled
by, or is under common control with the party in question; “Building’s Structure” means the Building’s exterior walls, roof, elevator shafts, footings, foundations, structural portions of load-bearing walls,
structural floors and subfloors, and structural columns and beams; “Building’s Systems” means the Building’s HVAC, life-safety, plumbing, electrical, and mechanical systems; “including” means
including, without limitation; “Laws” means all federal, state, and local laws, ordinances, rules and regulations, all court orders, governmental directives, and governmental orders and all interpretations of the foregoing,
and all restrictive covenants affecting the Project, and “Law” means any of the foregoing; “Tenant’s Off-Premises Equipment” means any of Tenant’s equipment or other property that may be
located on or about the Project (other than inside the Premises); and “Tenant Party” means any of the following persons: Tenant; any assignees claiming by, through, or under Tenant; any subtenants claiming by, through, or
under Tenant; and any of their respective agents, contractors, employees, licensees, guests and invitees. 
 2. Lease Grant.
Subject to the terms of this Lease, Landlord leases to Tenant, and Tenant leases from Landlord, the Premises. 
 3. Tender of
Possession. Landlord and Tenant presently anticipate that possession of the Premises will be tendered to Tenant in the condition required by this Lease on or about February 1, 2007 (the “Estimated Delivery
Date”). If Landlord is unable to tender possession of the Premises in such condition to Tenant by the Estimated Delivery Date, then (a) the validity of this Lease shall not be affected or impaired thereby, (b) Landlord shall
not be in default hereunder or be liable for damages therefor, and (c) Tenant shall accept possession of the Premises when Landlord tenders possession thereof to Tenant. By occupying the Premises, Tenant shall be deemed to have accepted the
Premises in their condition as of the date of such occupancy, subject to the performance of punch-list items that remain to be performed by Landlord, if any. Prior to occupying the Premises, Tenant shall execute and deliver to Landlord a letter
substantially in the form of Exhibit E hereto confirming (1) the Rent Commencement Date and the expiration date of the initial Term, (2) that Tenant has accepted the Premises, and (3) that Landlord has performed all of its
obligations with respect to the Premises (except for punch-list items specified in such letter); however, the failure of the parties to execute such letter shall not defer the Rent Commencement Date or otherwise invalidate this Lease. Occupancy of
the Premises by Tenant prior to the Rent Commencement Date shall be subject to all of the provisions of this Lease excepting only those requiring the payment of Basic Rent, Additional Rent, Taxes and Electrical Costs (each as defined herein).

 4. Rent. 
 (a) Payment. Tenant shall timely pay to Landlord Rent, without notice, demand, deduction or set off (except as otherwise expressly provided herein), by good and sufficient check drawn on a national
banking association at Landlord’s address provided for in this Lease or as otherwise specified by Landlord and shall be accompanied by all applicable state and local sales or use taxes. The obligations of Tenant to pay Basic Rent and other sums
to Landlord and the obligations of Landlord under this Lease are independent obligations. Basic Rent, adjusted as herein provided, shall be payable monthly in advance. The first monthly installment of Basic Rent shall be payable contemporaneously
with the execution of this Lease; thereafter, Basic Rent shall be payable on the first day of each month beginning on the first day of the second full calendar month of the Term. The monthly Basic Rent for any partial month at the beginning of the
Term shall equal the product of 1/365 of the annual Basic Rent in effect during the partial month and the number of days in the partial month and shall be due on the Rent Commencement Date.

 PLANO, TEXAS










 
Payments of Basic Rent for any fractional calendar month at the end of the Term shall be similarly prorated. Tenant shall pay Additional Rent at the same
time and in the same manner as Basic Rent. 
 (b) Operating Costs; Taxes; Electrical Costs. 
 (1) Tenant shall pay to Landlord the amount (per each rentable square foot in the Premises) (“Additional Rent”) by
which the annual Operating Costs (defined below) per rentable square foot in the Complex exceed the Expense Stop (per rentable square foot in the Complex). Landlord may make a good faith estimate of the Additional Rent to be due by Tenant for any
calendar year or part thereof during the Term. During each calendar year or partial calendar year of the Term (after the base year, if the Expense Stop is calculated on a base year basis), Tenant shall pay to Landlord, in advance concurrently with
each monthly installment of Basic Rent, an amount equal to the estimated Additional Rent for such calendar year or part thereof divided by the number of months therein. From time to time, Landlord may estimate and re-estimate the Additional Rent to
be due by Tenant and deliver a copy of the estimate or re-estimate to Tenant. Thereafter, the monthly installments of Additional Rent payable by Tenant shall be appropriately adjusted in accordance with the estimations so that, by the end of the
calendar year in question, Tenant shall have paid all of the Additional Rent as estimated by Landlord. Any amounts paid based on such an estimate shall be subject to adjustment as herein provided when actual Operating Costs are available for each
calendar year. 
 (2) The term “Operating Costs” means all expenses and disbursements (subject to the
limitations set forth below) that Landlord incurs in connection with the ownership, operation, and maintenance of the Complex, determined in accordance with sound accounting principles consistently applied, including the following costs:
(A) wages and salaries of all on-site employees at or below the grade of senior building manager engaged in the operation, maintenance or security of the Complex (together with Landlord’s reasonable allocation of expenses of off-site
employees at or below the grade of senior building manager who perform a portion of their services in connection with the operation, maintenance or security of the Complex), including taxes, insurance and benefits relating thereto; (B) all
supplies and materials used in the operation, maintenance, repair, replacement, and security of the Complex; (C) costs for improvements made to the Complex which, although capital in nature, are expected to reduce the normal operating costs
(including all utility costs) of the Complex, as amortized using a commercially reasonable interest rate over the time period reasonably estimated by Landlord to recover the costs thereof taking into consideration the anticipated cost savings, as
determined by Landlord using its good faith, commercially reasonable judgment, as well as capital improvements made in order to comply with any Law hereafter promulgated by any governmental authority or any interpretation hereafter rendered with
respect to any existing Law, as amortized using a commercially reasonable interest rate over the useful economic life of such improvements as determined by Landlord in its reasonable discretion; (D) cost of all utilities, except Electrical
Costs and the cost of other utilities reimbursable to Landlord by the Complex’s tenants other than pursuant to a provision similar to this Section 4(b); (E) insurance expenses; (F) repairs, replacements, and general maintenance
of the Complex; (G) fair market rental and other costs with respect to the management office for the Complex; and (H) service, maintenance and management contracts with independent contractors for the operation, maintenance, management,
repair, replacement, or security of the Complex (including alarm service, window cleaning, and elevator maintenance). 
 Operating Costs shall
not include costs for (i) capital improvements made to the Complex, other than capital improvements described in Section 4(b)(2)(C) and except for items which are generally considered maintenance and repair items, such as painting of
common areas, replacement of carpet in elevator lobbies, and the like; (ii) repair, replacements and general maintenance paid by proceeds of insurance or by Tenant or other third parties; (iii) interest, amortization or other payments on
loans to Landlord; (iv) depreciation; (v) leasing commissions; (vi) legal expenses for services, other than those that benefit the Complex tenants generally (e.g., tax disputes); (vii) renovating or otherwise improving space for
occupants of the Complex or vacant space in the Complex; (viii) Taxes; and (ix) federal income taxes imposed on or measured by the income of Landlord from the operation of the Complex. If the Expense Stop is calculated on a base year
basis,

Operating Costs for the base year only shall not include costs incurred due to extraordinary circumstances, including market-wide labor rate increases due to
boycotts and strikes; utility rate increases due to extraordinary circumstances, including conservation surcharges, boycotts, embargos or other shortages; insurance deductibles; or amortized costs relating to capital improvements. 
 (3) Tenant shall also pay Tenant’s Proportionate Share of any increase in Taxes for each year and partial year falling within the
Term over the Taxes for the Base Tax Year. Tenant shall pay Tenant’s Proportionate Share of Taxes in the same manner as provided above for Tenant’s Proportionate Share of Operating Costs. “Taxes” means taxes,
assessments, and governmental charges or fees whether federal, state, county or municipal, and whether they be by taxing districts or authorities presently taxing or by others, subsequently created or otherwise, and any other taxes and assessments
(including non-governmental assessments for common charges under a restrictive covenant or other private agreement that are not treated as part of Operating Costs) now or hereafter attributable to the Complex (or its operation), excluding, however,
penalties and interest thereon and federal and state taxes on income (if the present method of taxation changes so that in lieu of or in addition to the whole or any part of any Taxes, there is levied on Landlord a capital tax directly on the rents
received therefrom or a franchise tax, assessment, or charge based, in whole or in part, upon such rents for the Complex, then all such taxes, assessments, or charges, or the part thereof so based, shall be deemed to be included within the term
“Taxes” for purposes hereof). Notwithstanding anything to the contrary herein, Taxes shall include the Texas franchise tax and/or any other business tax imposed under Texas Tax Code Chapter 171 and/or any successor
statutory provision for reports due under any such provision. Taxes shall include the costs of consultants retained in an effort to lower taxes and all costs incurred in disputing any taxes or in seeking to lower the tax valuation of the Complex.
For property tax purposes, Tenant waives all rights to protest or appeal the appraised value of the Premises, as well as the Complex, and all rights to receive notices of reappraisement as set forth in Sections 41.413 and 42.015 of the Texas
Tax Code. 
 (4) Tenant shall also pay to Landlord Tenant’s Proportionate Share of the cost of all electricity used by
the Complex (“Electrical Costs”). Such amount shall be payable in monthly installments on the Rent Commencement Date and on the first day of each calendar month thereafter. Each installment shall be based on Landlord’s
estimate of the amount due for each month. From time to time during any calendar year, Landlord may estimate or re-estimate the Electrical Costs to be due by Tenant for that calendar year and deliver a copy of the estimate or re-estimate to Tenant.
Thereafter, the monthly installments of Electrical Costs payable by Tenant shall be appropriately adjusted in accordance with the estimations. 
 (5) By April 1 of each calendar year, or as soon thereafter as practicable, Landlord shall furnish to Tenant a statement of Operating Costs and Electrical Costs for the previous year, in each case adjusted as
provided in Section 4(b)(6), and of the Taxes for the previous year (the “Operating Costs and Tax Statement”). If Tenant’s estimated payments of Operating Costs, Electrical Costs or Taxes under this
Section 4(b) for the year covered by the Operating Costs and Tax Statement exceed Tenant’s Proportionate Share of such items as indicated in the Operating Costs and Tax Statement, then Landlord shall promptly credit or reimburse Tenant for
such excess; likewise, if Tenant’s estimated payments of Operating Costs, Electrical Costs or Taxes under this Section 4(b) for such year are less than Tenant’s Proportionate Share of such items as indicated in the Operating Costs and
Tax Statement, then Tenant shall promptly pay Landlord such deficiency. 
 (6) With respect to any calendar year or partial
calendar year in which the Complex is not occupied to the extent of 95% of the rentable area thereof, or Landlord is not supplying services to 95% of the rentable area thereof, the Operating Costs and Electrical Costs for such period which vary with
the occupancy of the Building shall, for the purposes hereof, be increased to the amount which would have been incurred had the Complex been occupied to the extent of 95% of the rentable area thereof and Landlord had been supplying services to 95%
of the rentable area thereof.

 5. Delinquent Payment; Handling Charges. All past due payments required of Tenant hereunder
shall bear interest from the date due until paid at the lesser of eighteen percent per annum or the maximum lawful rate of interest (such lesser amount is referred to herein as the “Default Rate”); additionally, Landlord, in
addition to all other rights and remedies available to it, may charge Tenant a fee equal to five percent of the delinquent payment to reimburse Landlord for its cost and inconvenience incurred as a consequence of Tenant’s delinquency. In no
event, however, shall the charges permitted under this Section 5 or elsewhere in this Lease, to the extent they are considered to be interest under applicable Law, exceed the maximum lawful rate of interest. Notwithstanding the foregoing, the
late fee referenced above shall not be charged with respect to the first occurrence (but not any subsequent occurrence) during any 12-month period that Tenant fails to make payment when due, until five days after Landlord delivers written notice of
such delinquency to Tenant. 
 6. Security Deposit. Contemporaneously with the execution of this Lease, Tenant shall pay to
Landlord the Security Deposit, which shall be held by Landlord to secure Tenant’s performance of its obligations under this Lease. The Security Deposit is not an advance payment of Rent or a measure or limit of Landlord’s damages upon an
Event of Default (as defined herein). Landlord may, from time to time following an Event of Default and without prejudice to any other remedy, use all or a part of the Security Deposit to perform any obligation Tenant fails to perform hereunder.
Following any such application of the Security Deposit, Tenant shall pay to Landlord on demand the amount so applied in order to restore the Security Deposit to its original amount. Provided that Tenant has performed all of its obligations
hereunder, Landlord shall, within 60 days after the expiration of the Term and Tenant’s surrender of the Premises in compliance with the provisions of this Lease, return to Tenant the portion of the Security Deposit which was not applied to
satisfy Tenant’s obligations. The Security Deposit may be commingled with other funds, and no interest shall be paid thereon. If Landlord transfers its interest in the Premises and the transferee assumes Landlord’s obligations under this
Lease, then Landlord may assign the Security Deposit to the transferee and Landlord thereafter shall have no further liability for the return of the Security Deposit. The rights and obligations of Landlord and Tenant under this Section 6 are
subject to any other requirements and conditions imposed by Laws applicable to the Security Deposit. 
 7. Landlord’s
Obligations. 
 (a) Services. Landlord shall use all reasonable efforts to furnish to Tenant:
(1) water at those points of supply provided for general use of tenants of the Building; (2) heated and refrigerated air conditioning (“HVAC”) as appropriate, at such temperatures and in such amounts as are standard
for comparable buildings in the vicinity of the Building; (3) janitorial service to the Premises on weekdays, other than holidays, for Building-standard installations and such window washing as may from time to time be reasonably required;
(4) elevators for ingress and egress to the floor on which the Premises are located, in common with other tenants, provided that Landlord may reasonably limit the number of operating elevators during non-business hours and holidays; and
(5) electrical current during normal business hours for equipment that does not require more than 110 volts and whose electrical energy consumption does not exceed normal office usage. Landlord shall maintain the common areas of the Building in
reasonably good order and condition, except for damage caused by a Tenant Party. If Tenant desires any of the services specified in Section 7(a)(2): (A) at any time other than between 7:00 a.m. and 6:00 p.m. on weekdays and between 8:00
a.m. and 1:00 p.m. on Saturday (in each case other than holidays), or (B) on Sunday or holidays, then such services shall be supplied to Tenant upon the written request of Tenant delivered to Landlord before 3:00 p.m. on the business day
preceding such extra usage, and Tenant shall pay to Landlord the cost of such services within 30 days after Landlord has delivered to Tenant an invoice therefor. The costs incurred by Landlord in providing after-hour HVAC service to Tenant shall
include costs for electricity, water, sewage, water treatment, labor, metering, filtering, and maintenance reasonably allocated by Landlord to providing such service. 
 (b) Excess Utility Use. Landlord shall not be required to furnish electrical current for equipment that requires more than
110 volts or other equipment whose electrical energy consumption exceeds normal office usage. If Tenant’s requirements for or consumption of electricity exceed the electricity to be provided by Landlord as described in Section 7(a),
Landlord shall, at Tenant’s expense, make reasonable efforts to supply such service through the then-existing feeders and risers serving the Building and the Premises, and Tenant shall pay to Landlord the cost of such service within 30 days
after Landlord has delivered to Tenant an invoice therefor. Landlord 

  


					
		  	4	  	 PRESTON PARK FINANCIAL CENTER
EAST
 PLANO, TEXAS










 
may determine the amount of such additional consumption and potential consumption by any verifiable method, including installation of a separate meter in the
Premises installed, maintained, and read by Landlord, at Tenant’s expense. Tenant shall not install any electrical equipment requiring special wiring or requiring voltage in excess of 110 volts unless approved in advance by Landlord, which
approval shall not be unreasonably withheld. Tenant shall not install any electrical equipment requiring voltage in excess of Building capacity unless approved in advance by Landlord, which approval may be withheld in Landlord’s sole
discretion. The use of electricity in the Premises shall not exceed the capacity of existing feeders and risers to or wiring in the Premises. Any risers or wiring required to meet Tenant’s excess electrical requirements shall, upon
Tenant’s written request, be installed by Landlord, at Tenant’s cost, if, in Landlord’s judgment, the same are necessary and shall not cause permanent damage to the Building or the Premises, cause or create a dangerous or hazardous
condition, entail excessive or unreasonable alterations, repairs, or expenses, or interfere with or disturb other tenants of the Building. If Tenant uses machines or equipment in the Premises which affect the temperature otherwise maintained by the
air conditioning system or otherwise overload any utility, Landlord may install supplemental air conditioning units or other supplemental equipment in the Premises, and the cost thereof, including the cost of installation, operation, use, and
maintenance, in each case plus an administrative fee of 15% of such cost, shall be paid by Tenant to Landlord within 30 days after Landlord has delivered to Tenant an invoice therefor. 
 (c) Restoration of Services; Abatement. Landlord shall use reasonable efforts to restore any service required of it that
becomes unavailable; however, such unavailability shall not render Landlord liable for any damages caused thereby, be a constructive eviction of Tenant, constitute a breach of any implied warranty, or, except as provided in the next sentence,
entitle Tenant to any abatement of Tenant’s obligations hereunder. If, however, Tenant is prevented from using the Premises because of the unavailability of any such service for a period of 25 consecutive business days following Landlord’s
receipt from Tenant of a written notice regarding such unavailability, the restoration of which is within Landlord’s reasonable control, and such unavailability was not caused by a Tenant Party or a governmental directive, then Tenant shall, as
its exclusive remedy be entitled to a reasonable abatement of Rent for each consecutive day (after such 25-day period) that Tenant is so prevented from using the Premises. 
 8. Improvements; Alterations; Repairs; Maintenance. 
 (a) Improvements; Alterations. Improvements to the Premises shall be installed at Tenant’s expense only in accordance
with plans and specifications which have been previously submitted to and approved in writing by Landlord, which approval shall be governed by the provisions set forth in this Section 8(a). No alterations or physical additions in or to the
Premises may be made without Landlord’s prior written consent, which shall not be unreasonably withheld or delayed; however, Landlord may withhold its consent to any alteration or addition that would adversely affect (in the reasonable
discretion of Landlord) the (1) Building’s Structure or the Building’s Systems (including the Building’s restrooms or mechanical rooms), (2) exterior appearance of the Building, (3) appearance of the Building’s
common areas or elevator lobby areas, or (4) provision of services to other occupants of the Building. Tenant shall not paint or install lighting or decorations, signs, window or door lettering, or advertising media of any type visible from the
exterior of the Premises without the prior written consent of Landlord, which consent may be withheld in Landlord’s sole and absolute discretion. All alterations, additions, and improvements shall be constructed, maintained, and used by Tenant,
at its risk and expense, in accordance with all Laws; Landlord’s consent to or approval of any alterations, additions or improvements (or the plans therefor) shall not constitute a representation or warranty by Landlord, nor Landlord’s
acceptance, that the same comply with sound architectural and/or engineering practices or with all applicable Laws, and Tenant shall be solely responsible for ensuring all such compliance. 
 (b) Repairs; Maintenance. Tenant shall maintain the Premises in a clean, safe, and operable condition, and shall not permit
or allow to remain any waste or damage to any portion of the Premises. Additionally, Tenant, at its sole expense, shall repair, replace and maintain in good condition and in accordance with all Laws and the equipment manufacturer’s suggested
service programs, all portions of the Premises, Tenant’s Off-Premises Equipment and all areas, improvements and systems exclusively serving the Premises. Tenant shall repair or replace, subject to Landlord’s direction and supervision, any
damage to the Building caused by a Tenant Party. If Tenant fails to make such repairs or replacements within 15 days after the occurrence of such damage, then Landlord may make the 

  


					
		  	5	  	 PRESTON PARK FINANCIAL CENTER
EAST
 PLANO, TEXAS










 
same at Tenant’s cost. If any such damage occurs outside of the Premises, then Landlord may elect to repair such damage at Tenant’s expense, rather
than having Tenant repair such damage. The cost of all maintenance, repair or replacement work performed by Landlord under this Section 8 shall be paid by Tenant to Landlord within 30 days after Landlord has invoiced Tenant therefor.

 (c) Performance of Work. All work described in this Section 8 shall be performed only by Landlord or by
contractors and subcontractors approved in writing by Landlord. Tenant shall cause all contractors and subcontractors to procure and maintain insurance coverage naming Landlord, Landlord’s property management company and Landlord’s asset
management company as additional insureds against such risks, in such amounts, and with such companies as Landlord may reasonably require. Tenant shall provide Landlord with the identities, mailing addresses and telephone numbers of all persons
performing work or supplying materials prior to beginning such construction and Landlord may post on and about the Premises notices of non-responsibility pursuant to applicable Laws. All such work shall be performed in accordance with all Laws and
in a good and workmanlike manner so as not to damage the Building (including the Premises, the Building’s Structure and the Building’s Systems). All such work which may affect the Building’s Structure or the Building’s Systems
must be approved by the Building’s engineer of record, at Tenant’s expense and, at Landlord’s election, must be performed by Landlord’s usual contractor for such work. All work affecting the roof of the Building must be performed
by Landlord’s roofing contractor and no such work will be permitted if it would void or reduce the warranty on the roof. 
 (d) Mechanic’s Liens. All work performed, materials furnished, or obligations incurred by or at the request of a Tenant Party shall be deemed authorized and ordered by Tenant only, and Tenant shall not permit any
mechanic’s liens to be filed against the Premises or the Project in connection therewith. Upon completion of any such work, Tenant shall deliver to Landlord final lien waivers from all contractors, subcontractors and materialmen who performed
such work. If such a lien is filed, then Tenant shall, within ten days after Landlord has delivered notice of the filing thereof to Tenant (or such earlier time period as may be necessary to prevent the forfeiture of the Premises, the Project or any
interest of Landlord therein or the imposition of a civil or criminal fine with respect thereto), either (1) pay the amount of the lien and cause the lien to be released of record, or (2) diligently contest such lien and deliver to
Landlord a bond or other security reasonably satisfactory to Landlord. If Tenant fails to timely take either such action, then Landlord may pay the lien claim, and any amounts so paid, including expenses and interest, shall be paid by Tenant to
Landlord within ten days after Landlord has invoiced Tenant therefor. Landlord and Tenant acknowledge and agree that their relationship is and shall be solely that of “landlord-tenant” (thereby excluding a relationship of
“owner-contractor,” “owner-agent” or other similar relationships). Accordingly, all materialmen, contractors, artisans, mechanics, laborers and any other persons now or hereafter contracting with Tenant, any contractor or
subcontractor of Tenant or any other Tenant Party for the furnishing of any labor, services, materials, supplies or equipment with respect to any portion of the Premises, at any time from the date hereof until the end of the Term, are hereby charged
with notice that they look exclusively to Tenant to obtain payment for same. Nothing herein shall be deemed a consent by Landlord to any liens being placed upon the Premises, the Project or Landlord’s interest therein due to any work performed
by or for Tenant or deemed to give any contractor or subcontractor or materialman any right or interest in any funds held by Landlord to reimburse Tenant for any portion of the cost of such work. Tenant shall defend, indemnify and hold harmless
Landlord and its agents and representatives from and against all claims, demands, causes of action, suits, judgments, damages and expenses (including attorneys’ fees) in any way arising from or relating to the failure by any Tenant Party to pay
for any work performed, materials furnished, or obligations incurred by or at the request of a Tenant Party. This indemnity provision shall survive termination or expiration of this Lease. 
 9. Use. Tenant shall continuously occupy and use the Premises only for the Permitted Use and shall comply with all Laws relating to the
use, condition, access to, and occupancy of the Premises and will not commit waste, overload the Building’s Structure or the Building’s Systems or subject the Premises to use that would damage the Premises. The population density within
the Premises as a whole shall at no time exceed one person for each 300 rentable square feet in the Premises. Tenant shall not conduct second or third shift operations within the Premises; however, Tenant may use the Premises after normal business
hours, so long as Tenant is not generally conducting business from the Premises after normal business hours. Notwithstanding anything in this Lease to the contrary, as between Landlord and Tenant, (a) Tenant shall bear the risk of complying
with Title III of the Americans With 

  


					
		  	6	  	 PRESTON PARK FINANCIAL CENTER
EAST
 PLANO, TEXAS










 
Disabilities Act of 1990, any state laws governing handicapped access or architectural barriers, and all rules, regulations, and guidelines promulgated under
such laws, as amended from time to time (the “Disabilities Acts”) in the Premises, and (b) Landlord shall bear the risk of complying with the Disabilities Acts in the common areas of the Building, other than compliance that
is necessitated by the use of the Premises for other than the Permitted Use or as a result of any alterations or additions, including any initial tenant improvement work, made by or on behalf of a Tenant Party (which risk and responsibility shall be
borne by Tenant). The Premises shall not be used for any use which is disreputable, creates extraordinary fire hazards, or results in an increased rate of insurance on the Building or its contents, or for the storage of any Hazardous Materials
(other than typical office supplies [e.g., photocopier toner] and then only in compliance with all Laws). Tenant shall not use the Premises to conduct as its primary business the retail or discount sale of securities. Tenant shall not use any
substantial portion of the Premises for a “call center,” any other telemarketing use, or any credit processing use. If, because of a Tenant Party’s acts or because Tenant vacates the Premises, the rate of insurance on the Building or
its contents increases, then such acts shall be an Event of Default, Tenant shall pay to Landlord the amount of such increase on demand, and acceptance of such payment shall not waive any of Landlord’s other rights. Tenant shall conduct its
business and control each other Tenant Party so as not to create any nuisance or unreasonably interfere with other tenants or Landlord in its management of the Building. 
 10. Assignment and Subletting. 
 (a) Transfers. Except as
provided in Section 10(h), Tenant shall not, without the prior written consent of Landlord, (1) assign, transfer, or encumber this Lease or any estate or interest herein, whether directly or by operation of law, (2) permit any other
entity to become Tenant hereunder by merger, consolidation, or other reorganization, (3) if Tenant is an entity other than a corporation whose stock is publicly traded, permit the transfer of an ownership interest in Tenant so as to result in a
change in the current control of Tenant, (4) sublet any portion of the Premises, (5) grant any license, concession, or other right of occupancy of any portion of the Premises, or (6) permit the use of the Premises by any parties other
than Tenant (any of the events listed in Section 10(a)(1) through 10(a)(6) being a “Transfer”). 
 (b) Consent Standards. Landlord shall not unreasonably withhold its consent to any assignment or subletting of the Premises, provided that the proposed transferee (1) is creditworthy, (2) has a good reputation in the
business community, (3) will use the Premises for the Permitted Use (thus, excluding, without limitation, uses for credit processing and telemarketing) and will not use the Premises in any manner that would conflict with any exclusive use
agreement or other similar agreement entered into by Landlord with any other tenant of the Building or Complex, (4) will not use the Premises, Building or Project in a manner that would materially increase the pedestrian or vehicular traffic to
the Premises, Building or Project, (5) is not a governmental entity, or subdivision or agency thereof, (6) is not another occupant of the Building or Complex, and (7) is not a person or entity with whom Landlord is then, or has been
within the six-month period prior to the time Tenant seeks to enter into such assignment or subletting, negotiating to lease space in the Building or Complex or any Affiliate of any such person or entity; otherwise, Landlord may withhold its consent
in its sole discretion. Additionally, Landlord may withhold its consent in its sole discretion to any proposed Transfer if any Event of Default by Tenant then exists. 
 (c) Request for Consent. If Tenant requests Landlord’s consent to a Transfer, then, at least 15 business days prior to
the effective date of the proposed Transfer, Tenant shall provide Landlord with a written description of all terms and conditions of the proposed Transfer, copies of the proposed documentation, and the following information about the proposed
transferee: name and address; reasonably satisfactory information about its business and business history; its proposed use of the Premises; banking, financial, and other credit information; and general references sufficient to enable Landlord to
determine the proposed transferee’s creditworthiness and character. Concurrently with Tenant’s notice of any request for consent to a Transfer, Tenant shall pay to Landlord a fee of $1,000 to defray Landlord’s expenses in reviewing
such request, and Tenant shall also reimburse Landlord immediately upon request for its reasonable attorneys’ fees incurred in connection with considering any request for consent to a Transfer.

 PLANO, TEXAS










 (d) Conditions to Consent. If Landlord consents to a proposed Transfer,
then the proposed transferee shall deliver to Landlord a written agreement whereby it expressly assumes Tenant’s obligations hereunder; however, any transferee of less than all of the space in the Premises shall be liable only for obligations
under this Lease that are properly allocable to the space subject to the Transfer for the period of the Transfer. No Transfer shall release Tenant from its obligations under this Lease, but rather Tenant and its transferee shall be jointly and
severally liable therefor. Landlord’s consent to any Transfer shall not waive Landlord’s rights as to any subsequent Transfers. If an Event of Default occurs while the Premises or any part thereof are subject to a Transfer, then Landlord,
in addition to its other remedies, may collect directly from such transferee all rents becoming due to Tenant and apply such rents against Rent. Tenant authorizes its transferees to make payments of rent directly to Landlord upon receipt of notice
from Landlord to do so following the occurrence of an Event of Default hereunder. Tenant shall pay for the cost of any demising walls or other improvements necessitated by a proposed subletting or assignment. 
 (e) Attornment by Subtenants. Each sublease by Tenant hereunder shall be subject and subordinate to this Lease and to the
matters to which this Lease is or shall be subordinate, and each subtenant by entering into a sublease is deemed to have agreed that in the event of termination, re-entry or dispossession by Landlord under this Lease, Landlord may, at its option,
take over all of the right, title and interest of Tenant, as sublandlord, under such sublease, and such subtenant shall, at Landlord’s option, attorn to Landlord pursuant to the then executory provisions of such sublease, except that Landlord
shall not be (1) liable for any previous act or omission of Tenant under such sublease, (2) subject to any counterclaim, offset or defense that such subtenant might have against Tenant, (3) bound by any previous modification of such
sublease not approved by Landlord in writing or by any rent or additional rent or advance rent which such subtenant might have paid for more than the current month to Tenant, and all such rent shall remain due and owing, notwithstanding such advance
payment, (4) bound by any security or advance rental deposit made by such subtenant which is not delivered or paid over to Landlord and with respect to which such subtenant shall look solely to Tenant for refund or reimbursement, or
(5) obligated to perform any work in the subleased space or to prepare it for occupancy, and in connection with such attornment, the subtenant shall execute and deliver to Landlord any instruments Landlord may reasonably request to evidence and
confirm such attornment. Each subtenant or licensee of Tenant shall be deemed, automatically upon and as a condition of its occupying or using the Premises or any part thereof, to have agreed to be bound by the terms and conditions set forth in this
Section 10(e). The provisions of this Section 10(e) shall be self-operative, and no further instrument shall be required to give effect to this provision. 
 (f) Cancellation. Landlord may, within 30 days after submission of Tenant’s written request for Landlord’s
consent to an assignment or subletting, cancel this Lease as to the portion of the Premises proposed to be sublet or assigned as of the date the proposed Transfer is to be effective. If Landlord cancels this Lease as to any portion of the Premises,
then this Lease shall cease for such portion of the Premises and Tenant shall pay to Landlord all Rent accrued through the cancellation date relating to the portion of the Premises covered by the proposed Transfer. Thereafter, Landlord may lease
such portion of the Premises to the prospective transferee (or to any other person) without liability to Tenant. 
 (g)
Additional Compensation. Tenant shall pay to Landlord, immediately upon receipt thereof, the excess of (1) all compensation received by Tenant for a Transfer less the actual out-of-pocket costs reasonably incurred by Tenant with
unaffiliated third parties (i.e., brokerage commissions and tenant finish work) in connection with such Transfer (such costs shall be amortized on a straight-line basis over the term of the Transfer in question) over (2) the Rent allocable to
the portion of the Premises covered thereby. 
 (h) Permitted Transfers. Notwithstanding Section 10(a),
Tenant may Transfer all or part of its interest in this Lease or all or part of the Premises (a “Permitted Transfer”) to the following types of entities (a “Permitted Transferee”) without the written
consent of Landlord: 
 (1) an Affiliate of Tenant; 
 (2) any corporation, limited partnership, limited liability partnership, limited liability company or other business entity in which or
with which Tenant, or its corporate successors or assigns, is merged or consolidated, in accordance with applicable statutory provisions governing merger and consolidation of business entities, so long as (A) Tenant’s obligations hereunder
are assumed by the entity surviving such merger or created by such consolidation; and (B) the Tangible Net Worth of the surviving or created entity is not less than the Tangible Net Worth of Tenant as of the date hereof; or 
  


					
		  	8	  	 PRESTON PARK FINANCIAL CENTER
EAST
 PLANO, TEXAS










 (3) any corporation, limited partnership, limited liability partnership, limited
liability company or other business entity acquiring all or substantially all of Tenant’s assets, so long as (A) Tenant’s obligations hereunder are assumed by the entity surviving such merger or created by such consolidation; and
(B) such entity’s Tangible Net Worth after such acquisition is not less than the Tangible Net Worth of Tenant as of the date hereof. 
 Tenant shall promptly notify Landlord of any such Permitted Transfer. Tenant shall remain liable for the performance of all of the obligations of Tenant hereunder, or if Tenant no longer exists because of a merger, consolidation, or
acquisition, the surviving or acquiring entity shall expressly assume in writing the obligations of Tenant hereunder. Additionally, the Permitted Transferee shall comply with all of the terms and conditions of this Lease, including the Permitted
Use, and the use of the Premises by the Permitted Transferee may not violate any other agreements affecting the Premises, the Building or the Complex, Landlord or other tenants of the Building or the Complex. No later than 30 days after the
effective date of any Permitted Transfer, Tenant agrees to furnish Landlord with (i) copies of the instrument effecting any of the foregoing Transfers, (ii) documentation establishing Tenant’s satisfaction of the requirements set
forth above applicable to any such Transfer, and (iii) evidence of insurance as required under this Lease with respect to the Permitted Transferee. The occurrence of a Permitted Transfer shall not waive Landlord’s rights as to any
subsequent Transfers. “Tangible Net Worth” means the excess of total assets over total liabilities, in each case as determined in accordance with generally accepted accounting principles consistently applied
(“GAAP”), excluding, however, from the determination of total assets all assets which would be classified as intangible assets under GAAP including goodwill, licenses, patents, trademarks, trade names, copyrights, and
franchises. Any subsequent Transfer by a Permitted Transferee shall be subject to the terms of this Section 10. 
 (i)
Exclusive Use. Upon Tenant’s written request therefor, pursuant to a prospective Transfer and no more than once during any 12-month interval during the Term, Landlord shall provide to Tenant a description of all of the exclusive
use and similar agreements then existing between Landlord and the other tenants of the Complex. Tenant acknowledges that as part of an existing exclusive use agreement, Landlord shall not allow any tenant in the Complex to operate a retail or
discount brokerage office that sells securities as its primary business; accordingly, (1) it shall not be unreasonable for Landlord to withhold its consent to a proposed Transfer to any company that sells retail or discount securities as its
primary business, and (2) Tenant shall not sublease, assign or otherwise Transfer this Lease or any portion of the Premises to any company that sells retail or discount securities as its primary business without the express written consent of
Landlord, which consent may be withheld in Landlord’s sole and absolute discretion. 
 11. Insurance; Waivers; Subrogation;
Indemnity. 
 (a) Tenant’s Insurance. Effective as of the earlier of (1) the date Tenant
enters or occupies the Premises, or (2) the Rent Commencement Date, and continuing throughout the Term, Tenant shall maintain the following insurance policies: (A) commercial general liability insurance in amounts of $3,000,000 per
occurrence or, following the expiration of the initial Term, such other amounts as Landlord may from time to time reasonably require (and, if the use and occupancy of the Premises include any activity or matter that is or may be excluded from
coverage under a commercial general liability policy [e.g., the sale, service or consumption of alcoholic beverages], Tenant shall obtain such endorsements to the commercial general liability policy or otherwise obtain insurance to insure all
liability arising from such activity or matter [including liquor liability, if applicable] in such amounts as Landlord may reasonably require), insuring Tenant, Landlord, Landlord’s property management company, Landlord’s asset management
company and, if requested in writing by Landlord, Landlord’s Mortgagee, against all liability for injury to or death of a person or persons or damage to property arising from the use and occupancy of the Premises and (without implying any
consent by Landlord to the installation thereof) the installation, operation, maintenance, repair or removal of Tenant’s Off-Premises Equipment, (B) insurance covering the full value of all alterations and 

  


					
		  	9	  	 PRESTON PARK FINANCIAL CENTER
EAST
 PLANO, TEXAS










 
improvements and betterments in the Premises, naming Landlord and Landlord’s Mortgagee as additional loss payees as their interests may appear,
(C) insurance covering the full value of all furniture, trade fixtures and personal property (including property of Tenant or others) in the Premises or otherwise placed in the Project by or on behalf of a Tenant Party (including Tenant’s
Off-Premises Equipment), (D) contractual liability insurance sufficient to cover Tenant’s indemnity obligations hereunder (but only if such contractual liability insurance is not already included in Tenant’s commercial general
liability insurance policy), (E) worker’s compensation insurance, and (F) business interruption insurance in an amount reasonably acceptable to Landlord. Tenant’s insurance shall provide primary coverage to Landlord when any
policy issued to Landlord provides duplicate or similar coverage, and in such circumstance Landlord’s policy will be excess over Tenant’s policy. Tenant shall furnish to Landlord certificates of such insurance and such other evidence
satisfactory to Landlord of the maintenance of all insurance coverages required hereunder at least ten days prior to the earlier of the Rent Commencement Date or the date Tenant enters or occupies the Premises, and at least 15 days prior to each
renewal of said insurance, and Tenant shall obtain a written obligation on the part of each insurance company to notify Landlord at least 30 days before cancellation or a material change of any such insurance policies. All such insurance policies
shall be in form, and issued by companies reasonably satisfactory to Landlord. If Tenant fails to comply with the foregoing insurance requirements or to deliver to Landlord the certificates or evidence of coverage required herein, Landlord, in
addition to any other remedy available pursuant to this Lease or otherwise, may, but shall not be obligated to, obtain such insurance and Tenant shall pay to Landlord on demand the premium costs thereof, plus an administrative fee of 15% of such
cost. 
 (b) Landlord’s Insurance. Throughout the Term of this Lease, Landlord shall maintain, as a
minimum, the following insurance policies: (1) property insurance for the Building’s replacement value (excluding property required to be insured by Tenant), less a commercially-reasonable deductible if Landlord so chooses, and
(2) commercial general liability insurance in an amount of not less than $3,000,000. Landlord may, but is not obligated to, maintain such other insurance and additional coverages as it may deem necessary. The cost of all insurance carried by
Landlord with respect to the Project shall be included in Operating Costs. The foregoing insurance policies and any other insurance carried by Landlord shall be for the sole benefit of Landlord and under Landlord’s sole control, and Tenant
shall have no right or claim to any proceeds thereof or any other rights thereunder. Notwithstanding anything in this Lease to the contrary, Landlord’s indemnity obligations under this Lease shall be limited to the extent any such claim is
insured against under the terms of any insurance policy maintained by Landlord (or is required to be maintained by Landlord under the terms of this Lease). 
 (c) No Subrogation; Waiver of Property Claims. Landlord and Tenant each waives any claim it might have against the other for any damage to or theft, destruction, loss, or loss of use of any property, to
the extent the same is insured against under any insurance policy of the types described in this Section 11 that covers the Project, the Premises, Landlord’s or Tenant’s fixtures, personal property, leasehold improvements, or
business, or is required to be insured against under the terms hereof, regardless of whether the negligence of the other party caused such Loss (defined below). Additionally, Tenant waives any claim it may have against Landlord for any Loss
to the extent such Loss is caused by a terrorist act. Each party shall cause its insurance carrier to endorse all applicable policies waiving the carrier’s rights of recovery under subrogation or otherwise against the other party.
Notwithstanding any provision in this Lease to the contrary, Landlord, its agents, employees and contractors shall not be liable to Tenant or to any party claiming by, through or under Tenant for (and Tenant hereby releases Landlord and its
servants, agents, contractors, employees and invitees from any claim or responsibility for) any damage to or destruction, loss, or loss of use, or theft of any property of any Tenant Party located in or about the Project, caused by casualty, theft,
fire, third parties or any other matter or cause, regardless of whether the negligence of any party caused such loss in whole or in part. Tenant acknowledges that Landlord shall not carry insurance on, and shall not be responsible for damage
to, any property of any Tenant Party located in or about the Project. 
 (d) Indemnity. Subject to
Section 11(c), Tenant shall defend, indemnify, and hold harmless Landlord and its representatives and agents from and against all claims, demands, liabilities, causes of action, suits, judgments, damages, and expenses (including reasonable
attorneys’ fees) arising from any injury to or death of any person or the damage to or theft, destruction, loss, or loss of use of, any property or inconvenience (a “Loss”) (1) occurring in or on the Project (other
than within the Premises) to the extent caused by the negligence or willful misconduct of any Tenant Party, (2) occurring in the Premises, or (3) arising out of the installation, operation,

maintenance, repair or removal of any property of any Tenant Party located in or about the Project, including Tenant’s Off-Premises Equipment. It
being agreed that clauses (2) and (3) of this indemnity are intended to indemnify Landlord and its agents against the consequences of their own negligence or fault, even when Landlord or its agents are jointly, comparatively,
contributively, or concurrently negligent with Tenant, and even though any such claim, cause of action or suit is based upon or alleged to be based upon the strict liability of Landlord or its agents; however, such indemnity shall not apply to the
sole or gross negligence or willful misconduct of Landlord and its agents. Subject to Section 11(c), Landlord shall defend, indemnify, and hold harmless Tenant and its agents from and against all claims, demands, liabilities, causes of
action, suits, judgments, damages, and expenses (including reasonable attorneys’ fees) for any Loss arising from any occurrence in or on the Building’s common areas to the extent caused by the negligence or willful misconduct of Landlord
or its agents. The indemnities set forth in this Lease shall survive termination or expiration of this Lease and shall not terminate or be waived, diminished or affected in any manner by any abatement or apportionment of Rent under any provision of
this Lease. If any proceeding is filed for which indemnity is required hereunder, the indemnifying party agrees, upon request therefor, to defend the indemnified party in such proceeding at its sole cost utilizing counsel satisfactory to the
indemnified party. 
 12. Subordination; Attornment; Notice to Landlord’s Mortgagee. 
 (a) Subordination. This Lease shall be subordinate to any deed of trust, mortgage, or other security instrument (each, a
“Mortgage”), or any ground lease, master lease, or primary lease (each, a “Primary Lease”), that now or hereafter covers all or any part of the Premises (the mortgagee under any such Mortgage,
beneficiary under any such deed of trust, or the lessor under any such Primary Lease is referred to herein as a “Landlord’s Mortgagee”). Any Landlord’s Mortgagee may elect, at any time, unilaterally, to make this
Lease superior to its Mortgage, Primary Lease, or other interest in the Premises by so notifying Tenant in writing. The provisions of this Section shall be self-operative and no further instrument of subordination shall be required; however, in
confirmation of such subordination, Tenant shall execute and return to Landlord (or such other party designated by Landlord) within ten days after written request therefor such documentation, in recordable form if required, as a Landlord’s
Mortgagee may reasonably request to evidence the subordination of this Lease to such Landlord’s Mortgagee’s Mortgage or Primary Lease (including a subordination, non-disturbance and attornment agreement) or, if the Landlord’s
Mortgagee so elects, the subordination of such Landlord’s Mortgagee’s Mortgage or Primary Lease to this Lease. 
 (b) Attornment. Tenant shall attorn to any party succeeding to Landlord’s interest in the Premises, whether by purchase, foreclosure, deed in lieu of foreclosure, power of sale, termination of lease, or otherwise, upon
such party’s request, and shall execute such agreements confirming such attornment as such party may reasonably request. 
 (c) Notice to Landlord’s Mortgagee. Tenant shall not seek to enforce any remedy it may have for any default on the part of Landlord without first giving written notice by certified mail, return receipt requested,
specifying the default in reasonable detail, to any Landlord’s Mortgagee whose address has been given to Tenant, and affording such Landlord’s Mortgagee a reasonable opportunity to perform Landlord’s obligations hereunder. 

(d) Landlord’s Mortgagee’s Protection Provisions. If Landlord’s Mortgagee shall succeed to the interest of
Landlord under this Lease, Landlord’s Mortgagee shall not be: (1) liable for any act or omission of any prior lessor (including Landlord); (2) bound by any rent or additional rent or advance rent which Tenant might have paid for more
than the current month to any prior lessor (including Landlord), and all such rent shall remain due and owing, notwithstanding such advance payment; (3) bound by any security or advance rental deposit made by Tenant which is not delivered or
paid over to Landlord’s Mortgagee and with respect to which Tenant shall look solely to Landlord for refund or reimbursement; (4) bound by any termination, amendment or modification of this Lease made without Landlord’s
Mortgagee’s consent and written approval, except for those terminations, amendments and modifications permitted to be made by Landlord without Landlord’s Mortgagee’s consent pursuant to the terms of the loan documents between Landlord
and Landlord’s Mortgagee; (5) subject to the defenses which Tenant might have against any prior lessor (including Landlord); and (6) subject to the offsets which Tenant might have against any prior

lessor (including Landlord) except for those offset rights which (A) are expressly provided in this Lease, (B) relate to periods of time following
the acquisition of the Building by Landlord’s Mortgagee, and (C) Tenant has provided written notice to Landlord’s Mortgagee and provided Landlord’s Mortgagee a reasonable opportunity to cure the event giving rise to such offset
event. Landlord’s Mortgagee shall have no liability or responsibility under or pursuant to the terms of this Lease or otherwise after it ceases to own an interest in the Project. Nothing in this Lease shall be construed to require
Landlord’s Mortgagee to see to the application of the proceeds of any loan, and Tenant’s agreements set forth herein shall not be impaired on account of any modification of the documents evidencing and securing any loan. 
 13. Rules and Regulations. Tenant shall comply with the rules and regulations of the Project which are attached hereto as Exhibit C.
Landlord may, from time to time, change such rules and regulations for the safety, care, or cleanliness of the Project and related facilities, provided that such changes are applicable to all tenants of the Project, will not unreasonably interfere
with Tenant’s use of the Premises and are enforced by Landlord in a non-discriminatory manner. Tenant shall be responsible for the compliance with such rules and regulations by each Tenant Party. 
 14. Condemnation. 
 (a) Total Taking. If the entire Building or Premises are taken by right of eminent domain or conveyed in lieu thereof (a “Taking”), this Lease shall terminate as of the date of the Taking. 

(b) Partial Taking - Tenant’s Rights. If any part of the Building becomes subject to a Taking and such Taking will
prevent Tenant from conducting on a permanent basis its business in the Premises in a manner reasonably comparable to that conducted immediately before such Taking, then Tenant may terminate this Lease as of the date of such Taking by giving written
notice to Landlord within 30 days after the Taking, and Basic Rent and Additional Rent shall be apportioned as of the date of such Taking. If Tenant does not terminate this Lease, then Rent shall be abated on a reasonable basis as to that portion of
the Premises rendered untenantable by the Taking. 
 (c) Partial Taking - Landlord’s Rights. If any
material portion, but less than all, of the Building becomes subject to a Taking, or if Landlord is required to pay any of the proceeds arising from a Taking to a Landlord’s Mortgagee, then Landlord may terminate this Lease by delivering
written notice thereof to Tenant within 30 days after such Taking, and Basic Rent and Additional Rent shall be apportioned as of the date of such Taking. If Landlord does not so terminate this Lease, then this Lease will continue, but if any portion
of the Premises has been taken, Rent shall abate as provided in the last sentence of Section 14(b). 
 (d)
Temporary Taking. If all or any portion of the Premises becomes subject to a Taking 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, including the payment of Basic Rent and all other amounts required hereunder. If any such temporary Taking terminates prior to the expiration of the Term, Tenant shall restore the Premises as nearly as possible to the
condition prior to such temporary Taking, at Tenant’s sole cost and expense. Landlord shall be entitled to receive the entire award for any such temporary Taking, except that Tenant shall be entitled to receive the portion of such award which
(1) compensates Tenant for its loss of use of the Premises within the Term and (2) reimburses Tenant for the reasonable out-of-pocket costs actually incurred by Tenant to restore the Premises as required by this Section. 
 (e) Award. If any Taking occurs, then Landlord shall receive the entire award or other compensation for the Land, the
Building, and other improvements taken; however, Tenant may separately pursue a claim (to the extent it will not reduce Landlord’s award) against the condemnor for the value of Tenant’s personal property which Tenant is entitled to remove
under this Lease, moving costs, loss of business, and other claims it may have.

 15. Fire or Other Casualty. 
 (a) Repair Estimate. If the Premises or the Building are damaged by fire or other casualty (a “Casualty”),
Landlord shall, within 90 days after such Casualty, deliver to Tenant a good faith estimate (the “Damage Notice”) of the time needed to repair the damage caused by such Casualty. 
 (b) Tenant’s Rights. If a material portion of the Premises is damaged by Casualty such that Tenant is prevented from
conducting its business in the Premises in a manner reasonably comparable to that conducted immediately before such Casualty and Landlord estimates that the damage caused thereby cannot be repaired within 270-E days after the commencement of repairs
(the “Repair Period”), then Tenant may terminate this Lease by delivering written notice to Landlord of its election to terminate within 30 days after the Damage Notice has been delivered to Tenant. 
 (c) Landlord’s Rights. If a Casualty damages the Premises or a material portion of the Building and (1) Landlord
estimates that the damage to the Premises cannot be repaired within the Repair Period, (2) the damage to the Premises exceeds 50% of the replacement cost thereof (excluding foundations and footings), as estimated by Landlord, and such damage
occurs during the last two years of the Term, (3) regardless of the extent of damage to the Premises, the damage is not fully covered by Landlord’s insurance policies or Landlord makes a good faith determination that restoring the Building
would be uneconomical, or (4) Landlord is required to pay any insurance proceeds arising out of the Casualty to a Landlord’s Mortgagee, then Landlord may terminate this Lease by giving written notice of its election to terminate within 30
days after the Damage Notice has been delivered to Tenant. 
 (d) Repair Obligation. If neither party elects to
terminate this Lease following a Casualty, then Landlord shall, within a reasonable time after such Casualty, begin to repair the Premises and shall proceed with reasonable diligence to restore the Premises to substantially the same condition as
they existed immediately before such Casualty; however, Landlord shall not be required to repair or replace any alterations or betterments within the Premises (which shall be promptly and with due diligence repaired and restored by Tenant at
Tenant’s sole cost and expense) or any furniture, equipment, trade fixtures or personal property of Tenant or others in the Premises or the Building, and Landlord’s obligation to repair or restore the Premises shall be limited to the
extent of the insurance proceeds actually received by Landlord for the Casualty in question. If this Lease is terminated under the provisions of this Section 15, Landlord shall be entitled to the full proceeds of the insurance policies
providing coverage for all alterations, improvements and betterments in the Premises (and, if Tenant has failed to maintain insurance on such items as required by this Lease, Tenant shall pay Landlord an amount equal to the proceeds Landlord would
have received had Tenant maintained insurance on such items as required by this Lease). 
 (e) Abatement of
Rent. If the Premises are damaged by Casualty, Rent for the portion of the Premises rendered untenantable by the damage shall be abated on a reasonable basis from the date of damage until the completion of Landlord’s repairs (or until
the date of termination of this Lease by Landlord or Tenant as provided above, as the case may be), unless a Tenant Party caused such damage, in which case, Tenant shall continue to pay Rent without abatement. 
 16. Personal Property Taxes. Tenant shall be liable for all taxes levied or assessed against personal property, furniture, or fixtures
placed by Tenant in the Premises or in or on the Building or Project. If any taxes for which Tenant is liable are levied or assessed against Landlord or Landlord’s property and Landlord elects to pay the same, or if the assessed value of
Landlord’s property is increased by inclusion of such personal property, furniture or fixtures and Landlord elects to pay the taxes based on such increase, then Tenant shall pay to Landlord, within 30 days following written request therefor,
the part of such taxes for which Tenant is primarily liable hereunder; however, Landlord shall not pay such amount if Tenant notifies Landlord that it will contest the validity or amount of such taxes before Landlord makes such payment, and
thereafter diligently proceeds with such contest in accordance with Law and if the non-payment thereof does not pose a threat of loss or seizure of the Project or interest of Landlord therein or impose any fee or penalty against Landlord.

 17. Events of Default. Each of the following occurrences shall be an “Event of
Default”: 
 (a) Payment Default. Tenant’s failure to pay Rent within five days after Landlord
has delivered written notice to Tenant that the same is due; however, an Event of Default shall occur hereunder without any obligation of Landlord to give any notice if Tenant fails to pay Rent when due and, during the 12 month interval preceding
such failure, Landlord has given Tenant written notice of failure to pay Rent on one or more occasions; 
 (b)
Abandonment. Tenant (1) abandons or vacates the Premises or any substantial portion thereof or (2) fails to continuously operate its business in the Premises; 
 (c) Estoppel. Tenant fails to provide any estoppel certificate after Landlord’s written request therefor pursuant to
Section 25(e) and such failure shall continue for five days after Landlord’s second written notice thereof to Tenant; 
 (d) Insurance. Tenant fails to procure, maintain and deliver to Landlord evidence of the insurance policies and coverages as required under Section 11(a); 
 (e) Mechanic’s Liens. Tenant fails to pay and release of record, or diligently contest and bond around, any
mechanic’s lien filed against the Premises or the Project for any work performed, materials furnished, or obligation incurred by or at the request of Tenant, within the time and in the manner required by Section 8(d); 
 (f) Other Defaults. Tenant’s failure to perform, comply with, or observe any other agreement or obligation of Tenant
under this Lease and the continuance of such failure for a period of more than 30 days after Landlord has delivered to Tenant written notice thereof; and 
 (g) Insolvency. The filing of a petition by or against Tenant (the term “Tenant” shall include, for the purpose of this Section 17(g), any guarantor of Tenant’s obligations hereunder)
(1) in any bankruptcy or other insolvency proceeding; (2) seeking any relief under any state or federal debtor relief law; (3) for the appointment of a liquidator or receiver for all or substantially all of Tenant’s property or
for Tenant’s interest in this Lease; (4) for the reorganization or modification of Tenant’s capital structure; or (5) in any assignment for the benefit of creditors proceeding; however, if such a petition is filed against Tenant,
then such filing shall not be an Event of Default unless Tenant fails to have the proceedings initiated by such petition dismissed within 90 days after the filing thereof. 
 18. Remedies. Upon any Event of Default, Landlord may, in addition to all other rights and remedies afforded Landlord hereunder or by law
or equity, take any one or more of the following actions: 
 (a) Termination of Lease. Terminate this Lease by
giving Tenant written notice thereof, in which event Tenant shall pay to Landlord the sum of (1) all Rent accrued hereunder through the date of termination, (2) all amounts due under Section 19(a), and (3) an amount equal to
(A) the total Rent that Tenant would have been required to pay for the remainder of the Term discounted to present value at a per annum rate equal to the “Prime Rate” as published on the date this Lease is terminated by The Wall
Street Journal, Southwest Edition, in its listing of “Money Rates” minus one percent, minus (B) the then present fair rental value of the Premises for such period, similarly discounted; 
 (b) Termination of Possession. Terminate Tenant’s right to possess the Premises without terminating this Lease by
giving written notice thereof to Tenant, in which event Tenant shall pay to Landlord (1) all Rent and other amounts accrued hereunder to the date of termination of possession, (2) all amounts due from time to time under Section 19(a),
and (3) all Rent and other net sums required hereunder to be paid by Tenant during the remainder of the Term, diminished by any net sums thereafter received by Landlord through reletting the Premises during such period, after deducting all
costs incurred by Landlord in reletting the Premises. If Landlord elects to proceed under this Section 18(b), Landlord may remove all of Tenant’s property from the Premises and store the same in a public warehouse or elsewhere at the cost
of, and for the account of, Tenant, without becoming liable for any loss or damage which may be occasioned thereby. Landlord shall use reasonable efforts to relet the Premises on such terms as Landlord in its sole discretion may determine (including
a term different from the Term, rental concessions, and 

  


					
		  	14	  	 PRESTON PARK FINANCIAL CENTER
EAST
 PLANO, TEXAS










 
alterations to, and improvement of, the Premises); however, Landlord shall not be obligated to relet the Premises before leasing other portions of the
Building or Complex and Landlord shall not be obligated to accept any prospective tenant proposed by Tenant unless such proposed tenant meets all of Landlord’s leasing criteria. Landlord shall not be liable for, nor shall Tenant’s
obligations hereunder be diminished because of, Landlord’s failure to relet the Premises or to collect rent due for such reletting. Tenant shall not be entitled to the excess of any consideration obtained by reletting over the Rent due
hereunder. Reentry by Landlord in the Premises shall not affect Tenant’s obligations hereunder for the unexpired Term; rather, Landlord may, from time to time, bring an action against Tenant to collect amounts due by Tenant, without the
necessity of Landlord’s waiting until the expiration of the Term. Unless Landlord delivers written notice to Tenant expressly stating that it has elected to terminate this Lease, all actions taken by Landlord to dispossess or exclude Tenant
from the Premises shall be deemed to be taken under this Section 18(b). If Landlord elects to proceed under this Section 18(b), it may at any time elect to terminate this Lease under Section 18(a); 
 (c) Perform Acts on Behalf of Tenant. Perform any act Tenant is obligated to perform under the terms of this Lease (and
enter upon the Premises in connection therewith if necessary) in Tenant’s name and on Tenant’s behalf, without being liable for any claim for damages therefor, and Tenant shall reimburse Landlord on demand for any expenses which Landlord
may incur in thus effecting compliance with Tenant’s obligations under this Lease (including, but not limited to, collection costs and legal expenses), plus interest thereon at the Default Rate; 
 (d) Suspension of Services. Suspend any services required to be provided by Landlord hereunder without being liable for any
claim for damages therefor; or 
 (e) Alteration of Locks. Additionally, with or without notice, and to the
extent permitted by Law, Landlord may alter locks or other security devices at the Premises to deprive Tenant of access thereto, and Landlord shall not be required to provide a new key or right of access to Tenant. 
 19. Payment by Tenant; Non-Waiver; Cumulative Remedies. 
 (a) Payment by Tenant. Upon any Event of Default, Tenant shall pay to Landlord all costs incurred by Landlord (including
court costs and reasonable attorneys’ fees and expenses) in (1) obtaining possession of the Premises, (2) removing and storing Tenant’s or any other occupant’s property, (3) repairing, restoring, altering, remodeling,
or otherwise putting the Premises into condition acceptable to a new tenant, (4) if Tenant is dispossessed of the Premises and this Lease is not terminated, reletting all or any part of the Premises (including brokerage commissions, cost of
tenant finish work, and other costs incidental to such reletting), (5) performing Tenant’s obligations which Tenant failed to perform, and (6) enforcing, or advising Landlord of, its rights, remedies, and recourses arising out of the
default. To the full extent permitted by law, Landlord and Tenant agree the federal and state courts of the state in which the Premises are located shall have exclusive jurisdiction over any matter relating to or arising from this Lease and the
parties’ rights and obligations under this Lease. 
 (b) No Waiver. Landlord’s acceptance of Rent
following an Event of Default shall not waive Landlord’s rights regarding such Event of Default. No waiver by Landlord of any violation or breach of any of the terms contained herein shall waive Landlord’s rights regarding any future
violation of such term. Landlord’s acceptance of any partial payment of Rent shall not waive Landlord’s rights with regard to the remaining portion of the Rent that is due, regardless of any endorsement or other statement on any instrument
delivered in payment of Rent or any writing delivered in connection therewith; accordingly, Landlord’s acceptance of a partial payment of Rent shall not constitute an accord and satisfaction of the full amount of the Rent that is due.

 (c) Cumulative Remedies. Any and all remedies set forth in this Lease: (1) shall be in addition to any
and all other remedies Landlord may have at law or in equity, (2) shall be cumulative, and (3) may be pursued successively or concurrently as Landlord may elect. The exercise of any remedy by Landlord shall not be deemed an election of
remedies or preclude Landlord from exercising any other remedies in the future. Additionally, Tenant shall defend, indemnify and hold harmless Landlord, Landlord’s Mortgagee and their respective representatives and agents from and against all
claims, demands, liabilities, causes of action, suits, judgments, damages and expenses (including reasonable attorneys’ fees) arising from Tenant’s failure to perform its obligations under this Lease.

 20. Landlord’s Lien. In addition to any statutory landlord’s lien, now or
hereafter enacted, Tenant grants to Landlord, to secure performance of Tenant’s obligations hereunder, a security interest in all of Tenant’s property situated in or upon, or used in connection with, the Premises or the Project, and all
proceeds thereof (except merchandise sold in the ordinary course of business) (collectively, the “Collateral”), and the Collateral shall not be removed from the Premises or the Project without the prior written consent of
Landlord until all obligations of Tenant have been fully performed. Such personalty thus encumbered includes specifically all trade and other fixtures for the purpose of this Section 20 and inventory, equipment, contract rights, accounts
receivable and the proceeds thereof. Upon the occurrence of an Event of Default, Landlord may, in addition to all other remedies, without notice or demand except as provided below, exercise the rights afforded to a secured party under the Uniform
Commercial Code of the state in which the Premises are located (the “UCC”). To the extent the UCC requires Landlord to give to Tenant notice of any act or event and such notice cannot be validly waived before a default
occurs, then five-days’ prior written notice thereof shall be reasonable notice of the act or event. In order to perfect such security interest, Landlord may file any financing statement or other instrument necessary at Tenant’s expense at
the state and county Uniform Commercial Code filing offices. Tenant grants to Landlord a power of attorney to execute and file any financing statement or other instrument necessary to perfect Landlord’s security interest under this
Section 20, which power is coupled with an interest and is irrevocable during the Term. Landlord may also file a copy of this Lease as a financing statement to perfect its security interest in the Collateral. Within ten days following written
request therefor, Tenant shall execute financing statements to be filed of record to perfect Landlord’s security interest in the Collateral. 
 21. Surrender of Premises. No act by Landlord shall be deemed an acceptance of a surrender of the Premises, and no agreement to accept a surrender of the Premises shall be valid unless it is in writing and signed by Landlord.
At the expiration or termination of this Lease, Tenant shall deliver to Landlord the Premises with all improvements located therein in good repair and condition, free of Hazardous Materials placed on the Premises during the Term, broom-clean,
reasonable wear and tear (and condemnation and Casualty damage not caused by Tenant, as to which Sections 14 and 15 shall control) excepted, and shall deliver to Landlord all keys to the Premises. Provided that Tenant has performed all of its
obligations hereunder, Tenant may remove all unattached trade fixtures, furniture, and personal property placed in the Premises or elsewhere in the Building by Tenant (but Tenant may not remove any such item which was paid for, in whole or in part,
by Landlord or any wiring or cabling unless Landlord requires such removal). Additionally, at Landlord’s option, Tenant shall remove such alterations, additions, improvements, trade fixtures, personal property, equipment, wiring, conduits,
cabling, and furniture (including Tenant’s Off-Premises Equipment) as Landlord may request; however, Tenant shall not be required to remove any addition or improvement to the Premises or the Project if Landlord has specifically agreed in
writing that the improvement or addition in question need not be removed. Tenant shall repair all damage caused by such removal. All items not so removed shall, at Landlord’s option, be deemed to have been abandoned by Tenant and may be
appropriated, sold, stored, destroyed, or otherwise disposed of by Landlord without notice to Tenant and without any obligation to account for such items; any such disposition shall not be considered a strict foreclosure or other exercise of
Landlord’s rights in respect of the security interest granted under Section 20. The provisions of this Section 21 shall survive the end of the Term. 
 22. Holding Over. If Tenant fails to vacate the Premises at the end of the Term, then Tenant shall be a tenant at sufferance and, in addition to all other damages and remedies to which Landlord may be
entitled for such holding over, (a) Tenant shall pay, in addition to the other Rent, Basic Rent equal to the greater of (1) 200% of the Rent payable during the last month of the Term, or (2) 125% of the prevailing rental rate in the
Building for similar space, and (b) Tenant shall otherwise continue to be subject to all of Tenant’s obligations under this Lease. The provisions of this Section 22 shall not be deemed to limit or constitute a waiver of any other
rights or remedies of Landlord provided herein or at law. If Tenant fails to surrender the Premises upon the termination or expiration of this Lease, in addition to any other liabilities to Landlord accruing therefrom, Tenant shall protect, defend,
indemnify and hold Landlord harmless from all loss, costs (including reasonable attorneys’ fees) and liability resulting from such failure, including any claims made by any succeeding tenant founded upon such failure to surrender, and any lost
profits to Landlord resulting therefrom.

 23. Certain Rights Reserved by Landlord. Provided that the exercise of such rights does not
unreasonably interfere with Tenant’s occupancy of the Premises, Landlord shall have the following rights: 
 (a)
Building Operations. To decorate and to make inspections, repairs, alterations, additions, changes, or improvements, whether structural or otherwise, in and about the Project, or any part thereof; to enter upon the Premises (after
giving Tenant reasonable notice thereof, which may be oral notice, except in cases of real or apparent emergency, in which case no notice shall be required) and, during the continuance of any such work, to temporarily close doors, entryways, public
space, and corridors in the Building; to interrupt or temporarily suspend Building services and facilities; to change the name of the Building; and to change the arrangement and location of entrances or passageways, doors, and doorways, corridors,
elevators, stairs, restrooms, or other public parts of the Building; 
 (b) Security. To take such reasonable
measures as Landlord deems advisable for the security of the Building and its occupants; evacuating the Building for cause, suspected cause, or for drill purposes; temporarily denying access to the Building; and closing the Building after normal
business hours and on Sundays and holidays, subject, however, to Tenant’s right to enter when the Building is closed after normal business hours under such reasonable regulations as Landlord may prescribe from time to time; 
 (c) Prospective Purchasers and Lenders. To enter the Premises at all reasonable hours to show the Premises to prospective
purchasers or lenders; and 
 (d) Prospective Tenants. At any time during the last 12 months of the Term (or
earlier if Tenant has notified Landlord in writing that it does not desire to renew the Term) or at any time following the occurrence of an Event of Default, to enter the Premises at all reasonable hours to show the Premises to prospective tenants.

 24. Substitution Space. Landlord may, at Landlord’s expense, relocate Tenant within the Complex to space which is
comparable in size, utility and condition to the Premises. If Landlord relocates Tenant, Landlord shall reimburse Tenant for Tenant’s reasonable out-of-pocket expenses for moving Tenant’s furniture, equipment, and supplies from the
Premises to the relocation space and for reprinting Tenant’s stationery of the same quality and quantity as Tenant’s stationery supply on hand immediately before Landlord’s notice to Tenant of the exercise of this relocation right.
Upon such relocation, the relocation space shall be deemed to be the Premises and the terms of this Lease shall remain in full force and shall apply to the relocation space. No amendment or other instrument shall be necessary to effectuate the
relocation contemplated by this Section; however, if requested by Landlord, Tenant shall execute an appropriate amendment document within ten business days after Landlord’s written request therefor. If Tenant fails to execute such relocation
amendment within such time period, or if Tenant fails to relocate within the time period stated in Landlord’s relocation notice to Tenant (or, if such relocation space is not available on the date specified in Landlord’s relocation notice,
as soon thereafter as the relocation space becomes available and is tendered to Tenant in the condition required by this Lease), then, in addition to Landlord’s other remedies set forth in this Lease, at law and/or in equity, Landlord may
terminate this Lease by notifying Tenant in writing thereof at least 60 days prior to the termination date contained in Landlord’s termination notice. Time is of the essence with respect to Tenant’s obligations under this Section.

 25. Miscellaneous. 
 (a) Landlord Transfer. Landlord may transfer any portion of the Project and any of its rights under this Lease. If Landlord assigns its rights under this Lease, then Landlord shall thereby be released

 EXHIBIT D 
 TENANT FINISH-WORK: ALLOWANCE 
 (Landlord Performs the Work) 
 1. Acceptance of Premises. Except as set forth in this Exhibit, Tenant accepts the Premises in their “AS-IS” condition on
the date that this Lease is entered into. 
 2. Space Plans. 
 (a) Preparation and Delivery. Within two business days after Tenant’s execution of this Lease, Tenant shall meet with
Interprise Design or another design consultant selected by Landlord (the “Architect”) to discuss the nature and extent of all improvements that Tenant proposes to install in the Premises and, at such meeting, provide the
Architect with all necessary data and information needed by the Architect to prepare initial space plans therefor as required by this paragraph. On or before the tenth day following the date of this Lease, Landlord shall deliver to Tenant a space
plan prepared by the Architect depicting improvements to be installed in the Premises (the “Space Plans”). 
 (b) Approval Process. Tenant shall notify Landlord whether it approves of the submitted Space Plans within three business days after Landlord’s submission thereof. If Tenant disapproves of such Space Plans, then Tenant
shall notify Landlord thereof specifying in reasonable detail the reasons for such disapproval, in which case Landlord shall, within three business days after such notice, revise such Space Plans in accordance with Tenant’s objections and
submit to Tenant for its review and approval. Tenant shall notify Landlord in writing whether it approves of the resubmitted Space Plans within one business day after its receipt thereof. This process shall be repeated until the Space Plans have
been finally approved by Tenant and Landlord. If Tenant fails to notify Landlord that it disapproves of the initial Space Plans within three business days (or, in the case of resubmitted Space Plans, within one business day) after the submission
thereof, then Tenant shall be deemed to have approved the Space Plans in question. 
 3. Working Drawings. 
 (a) Preparation and Delivery. On or before the date which is 15 days following the date on which the Space Plans are
approved (or deemed approved) by Tenant and Landlord, Landlord shall cause to be prepared final working drawings of all improvements to be installed in the Premises and deliver the same to Tenant for its review and approval (which approval shall not
be unreasonably withheld, delayed or conditioned). Such working drawings shall be prepared by Interprise Design, or another design consultant selected by Landlord (whose fee shall be included in the Total Construction Costs [defined below]).

 (b) Approval Process. Tenant shall notify Landlord whether it approves of the submitted working drawings
within three business days after Landlord’s submission thereof. If Tenant disapproves of such working drawings, then Tenant shall notify Landlord thereof specifying in reasonable detail the reasons for such disapproval, in which case Landlord
shall, within three business days after such notice, revise such working drawings in accordance with Tenant’s objections and submit the revised working drawings to Tenant for its review and approval. Tenant shall notify Landlord in writing
whether it approves of the resubmitted working drawings within one business day after its receipt thereof. This process shall be repeated until the working drawings have been finally approved by Landlord and Tenant. If Tenant fails to notify
Landlord that it disapproves of the initial working drawings within three business days (or, in the case of resubmitted working drawings, within one business day) after the submission thereof, then Tenant shall be deemed to have approved the working
drawings in question. Any delay caused by Tenant’s unreasonable withholding of its consent or delay in giving its written approval as to such working drawings shall constitute a Tenant Delay Day (defined below). If the working drawings are not
fully approved (or deemed approved) by both Landlord and Tenant by the 15th business day after the delivery of the initial draft thereof to Tenant, then each day after such time period that such working drawings are not fully approved (or deemed
approved) by both Landlord and Tenant shall constitute a Tenant Delay Day.

 PLANO, TEXAS










 (c) Landlord’s Approval; Performance of Work. If any of Tenant’s
proposed construction work will affect the Building’s Structure or the Building’s Systems, then the working drawings pertaining thereto must be approved by the Building’s engineer of record. Landlord’s approval of such working
drawings shall not be unreasonably withheld, provided that (1) they comply with all Laws, (2) the improvements depicted thereon do not adversely affect (in the reasonable discretion of Landlord) the Building’s Structure or the
Building’s Systems (including the Building’s restrooms or mechanical rooms), the exterior appearance of the Building, or the appearance of the Building’s common areas or elevator lobby areas, (3) such working drawings are
sufficiently detailed to allow construction of the improvements in a good and workmanlike manner, and (4) the improvements depicted thereon conform to the rules and regulations promulgated from time to time by Landlord for the construction of
tenant improvements (a copy of which has been delivered to Tenant). As used herein, “Working Drawings” means the final working drawings approved by Landlord, as amended from time to time by any approved changes thereto, and
“Work” means all improvements to be constructed in accordance with and as indicated on the Working Drawings, together with any work required by governmental authorities to be made to other areas of the Building as a result of
the improvements indicated by the Working Drawings. Landlord’s approval of the Working Drawings shall not be a representation or warranty of Landlord that such drawings are adequate for any use or comply with any Law, but shall merely be the
consent of Landlord thereto. Tenant shall, at Landlord’s request, sign the Working Drawings to evidence its review and approval thereof. After the Working Drawings have been approved, Landlord shall cause the Work to be performed in substantial
accordance with the Working Drawings. 
 4. Bidding of Work. Prior to commencing the Work, Landlord shall competitively bid the
Work to three contractors approved by Landlord. If the estimated Total Construction Costs are expected to exceed the Construction Allowance, Tenant shall be allowed to review the submitted bids from such contractors to value engineer any of
Tenant’s requested alterations. In such case, Tenant shall notify Landlord of any items in the Working Drawings that Tenant desires to change within two business days after Landlord’s submission thereof to Tenant. If Tenant fails to notify
Landlord of its election within such two business day period, Tenant shall be deemed to have approved the bids. Within five business days following Landlord’s submission of the initial construction bids to Tenant under the foregoing provisions
(if applicable), Tenant shall have completed all of the following items: (a) finalized with Landlord’s representative and the proposed contractor, the pricing of any requested revisions to the bids for the Work, and (b) approved in
writing any overage in the Total Construction Costs in excess of the Construction Allowance, failing which each day after such five business day period shall constitute a Tenant Delay Day. 
 5. Change Orders. Tenant may initiate changes in the Work. Each such change must receive the prior written approval of Landlord, such
approval not to be unreasonably withheld or delayed; however, (a) if such requested change would adversely affect (in the reasonable discretion of Landlord) (1) the Building’s Structure or the Building’s Systems (including the
Building’s restrooms or mechanical rooms), (2) the exterior appearance of the Building, or (3) the appearance of the Building’s common areas or elevator lobby areas, or (b) if any such requested change might delay the Rent
Commencement Date, Landlord may withhold its consent in its sole and absolute discretion. Tenant shall, upon completion of the Work, cause to be prepared an accurate architectural “as-built” plan of the Work as constructed, which plan
shall be incorporated into this Exhibit D by this reference for all purposes. If Tenant requests any changes to the Work described in the Space Plans or the Working Drawings, then such increased costs and any additional design costs incurred
in connection therewith as the result of any such change shall be added to the Total Construction Costs. 
 6. Definitions. As
used herein, a “Tenant Delay Day” means each day of delay in the performance of the Work that occurs (a) because Tenant fails to timely furnish any information or deliver or approve any required documents such as the
Space Plans or Working Drawings (whether preliminary, interim revisions or final), pricing estimates, construction bids, and the like, (b) because of any change by Tenant to the Space Plans or Working Drawings, (c) because Tenant fails to
attend any meeting with Landlord, the Architect, any design professional, or any contractor, or their respective employees or representatives, as may be required or scheduled hereunder or otherwise necessary in connection with the preparation or
completion of any construction documents, such as the Space Plans or Working Drawings, or in connection with the performance of the Work, (d) because of any specification by Tenant of materials or installations in addition to or other than
Landlord’s standard finish-out materials, or (e) because a Tenant 

  


					
		  	2	  	 PRESTON PARK FINANCIAL CENTER
EAST
 PLANO, TEXAS










 
Party otherwise delays completion of the Work. As used herein “Substantial Completion,” “Substantially
Completed,” and any derivations thereof mean the Work in the Premises is substantially completed (as reasonably determined by Landlord) in substantial accordance with the Working Drawings. Substantial Completion shall have occurred even
though minor details of construction, decoration, landscaping and mechanical adjustments remain to be completed by Landlord. 
 7.
Walk-Through; Punchlist. When Landlord considers the Work in the Premises to be Substantially Completed, Landlord will notify Tenant and, within three business days thereafter, Landlord’s representative and Tenant’s
representative shall conduct a walk-through of the Premises and identify any necessary touch-up work, repairs and minor completion items that are necessary for final completion of the Work. Neither Landlord’s representative nor Tenant’s
representative shall unreasonably withhold his or her agreement on punchlist items. Landlord shall use reasonable efforts to cause the contractor performing the Work to complete all punchlist items within 30 days after agreement thereon; however,
Landlord shall not be obligated to engage overtime labor in order to complete such items. 
 8. Excess Costs. The entire cost
of performing the Work (including design of and space planning for the Work and preparation of the Working Drawings and the final “as-built” plan of the Work, costs of construction labor and materials, electrical usage during construction,
additional janitorial services, general tenant signage, related taxes and insurance costs, licenses, permits, certifications, surveys and other approvals required by Law, and the construction supervision fee referenced in Section 10 of this
Exhibit, all of which costs are herein collectively called the “Total Construction Costs”) in excess of the Construction Allowance (hereinafter defined) shall be paid by Tenant. Upon approval of the Working Drawings and
selection of a contractor, Tenant shall promptly (a) execute a work order agreement prepared by Landlord which identifies such drawings and itemizes the Total Construction Costs and sets forth the Construction Allowance, and (b) pay to
Landlord 90% of the amount by which Total Construction Costs exceed the Construction Allowance. Upon Substantial Completion of the Work and before Tenant occupies the Premises to conduct business therein, Tenant shall pay to Landlord an amount equal
to the Total Construction Costs (as adjusted for any approved changes to the Work), less (1) the amount of the advance payment already made by Tenant, and (2) the amount of the Construction Allowance. In the event of default of payment of such
excess costs, Landlord (in addition to all other remedies) shall have the same rights as for an Event of Default under this Lease. 
 9.
Construction Allowance. Landlord shall provide to Tenant a construction allowance not to exceed $22.00 per rentable square foot in the Premises (the “Construction Allowance”) to be applied toward the Total
Construction Costs, as adjusted for any changes to the Work. The Construction Allowance shall not be disbursed to Tenant in cash, but shall be applied by Landlord to the payment of the Total Construction Costs, if, as, and when the cost of the Work
is actually incurred and paid by Landlord. Tenant may use up to $2.00 per rentable square foot in the Premises of the Construction Allowance towards the cost of Tenant’s installation of telephone and data networks and other move related costs.
The Construction Allowance must be used (that is, the Work must be fully complete and the Construction Allowance disbursed) within six months following the Rent Commencement Date or shall be deemed forfeited with no further obligation by Landlord
with respect thereto, time being of the essence with respect thereto. 
 10. Construction Management. Landlord or its Affiliate
or agent shall supervise the Work, make disbursements required to be made to the contractor, and act as a liaison between the contractor and Tenant and coordinate the relationship between the Work, the Building and the Building’s Systems. In
consideration for Landlord’s construction supervision services, Tenant shall pay to Landlord a construction supervision fee equal to five percent of the Total Construction Costs.

obligations under the Lease or to the enforcement of any of the landlord’s rights thereunder. 
 7. Landlord has completed all
alterations, additions, painting and refurbishing to the Premises and the Property required to be performed by Landlord, and there are no rent concessions, rebates, free rents or similar inducements except as set forth in the Lease. 
 8. The Lease is subject and subordinate to any and all existing and future mortgages and any ground lease of the Premises. 
 9. Tenant acknowledges that if Lender succeeds to the interest of Landlord under the Lease, Lender shall not be liable for any act or omission of any
prior landlord (including Landlord), liable for the return of any advance rental deposit or any security deposit (unless such sums have actually been received by Lender as security for Tenant’s performance under the Lease), subject to any
offset or defense which Tenant may have against any such prior landlord or bound by any rent or additional rent Tenant may have paid for more than the current month, or bound by any assignment, surrender, termination, cancellation, waiver, release,
amendment or modification of the Lease not expressly permitted by the Lease made without its express written consent. 
 10. If Lender
succeeds to the interest of Landlord under the Lease by any means, Tenant agrees to attorn to Lender and be bound to Lender under all the terms of the Lease on the condition that Lender does not disturb the possession of the Tenant under the Lease

 EXHIBIT G 
 PARKING 
 Tenant shall be provided a total of 13 parking access cards permitting Tenant to use
up to 13 unreserved parking spaces, at no additional charge during the initial Term, in the parking facilities associated with the Building (the “Parking Area”) subject to such terms, conditions and regulations as are from
time to time applicable to patrons of the Parking Area. 
 Subject to availability and at Landlord’s discretion, Tenant may, by
delivering to Landlord no less than 30 days’ prior written notice, convert two of its 13 unreserved parking spaces to reserved parking spaces in the Parking Area by paying to Landlord, concurrently with Tenant’s payment of Basic Rent, the
monthly parking rent for such reserved parking spaces at the rate of $55.00 per reserved parking space per month (plus all applicable taxes) during the initial Term; provided, that Landlord shall provide any requested reserved spaces as soon as such
reserved spaces become available. Tenant’s election to use such reserved spaces shall remain effective until the end of the Term. 
 Tenant shall at all times comply with all Laws respecting the use of the Parking Area. Landlord reserves the right to adopt, modify, and enforce reasonable rules and regulations governing the use of the Parking Area from time to time
including any key-card, sticker, or other identification or entrance systems and hours of operations. Landlord may refuse to permit any person who violates such rules and regulations to park in the Parking Area, and any violation of the rules and
regulations shall subject the car to removal from the Parking Area. 
 Tenant may validate visitor parking by such method or methods as
Landlord may approve, at the validation rate from time to time generally applicable to visitor parking. Unless specified to the contrary above, the parking spaces provided hereunder shall be provided on an unreserved, “first-come, first
served” basis. Tenant acknowledges that Landlord has arranged or may arrange for the Parking Area to be operated by an independent contractor, not affiliated with Landlord. 
 There will be a replacement charge payable by Tenant equal to the amount posted from time to time by Landlord for loss of any magnetic parking card or
parking sticker issued by Landlord. 
 All motor vehicles (including all contents thereof) shall be parked in the Parking Area at the sole
risk of Tenant and each other Tenant Party, it being expressly agreed and understood Landlord has no duty to insure any of said motor vehicles (including the contents thereof), and Landlord is not responsible for the protection and security of such
vehicles. NOTWITHSTANDING ANYTHING TO THE CONTRARY CONTAINED IN THIS LEASE, LANDLORD SHALL HAVE NO LIABILITY WHATSOEVER FOR ANY PROPERTY DAMAGE OR LOSS WHICH MIGHT OCCUR ON THE PARKING AREA OR AS A RESULT OF OR IN CONNECTION WITH THE PARKING OF
MOTOR VEHICLES IN ANY OF THE PARKING SPACES. 
 If, for any reason, Landlord is unable to provide all or any portion of the parking
spaces to which Tenant is entitled hereunder, then Tenant’s obligation to pay for such parking spaces shall be abated for so long as Tenant does not have the use thereof; this abatement shall be in full settlement of all claims that Tenant
might otherwise have against Landlord because of Landlord’s failure or inability to provide Tenant with such parking spaces. Landlord shall not be responsible for enforcing Tenant’s parking rights against any third parties.

 EXHIBIT H 
 RIGHT OF FIRST REFUSAL 
 Subject to then-existing renewal or expansion options of other
tenants and provided no Event of Default then exists, if Landlord receives a bona fide offer from a third party (the “Third Party Offer”) to lease the space designated on Exhibit A (the “Refusal
Space”) and Landlord is willing to accept the terms of such Third Party Offer, Landlord shall offer to lease to Tenant the Refusal Space on the same terms and conditions as the Third Party Offer; such offer shall be in writing, specify
the rent to be paid for the Refusal Space, contain the basic terms and conditions of the Third Party Offer and the date on which the Refusal Space shall be included in the Premises (the “Refusal Notice”). The Refusal Notice
shall be substantially similar to the Refusal Notice attached to this Exhibit. Tenant shall notify Landlord in writing whether Tenant elects to lease the entire portion of the Refusal Space subject to the Third Party Offer on the same terms and
conditions as the Third Party Offer in the Refusal Notice, within five days after Landlord delivers to Tenant the Refusal Notice. If Tenant timely elects to lease the Refusal Space within such five day period, then Landlord and Tenant shall execute
an amendment to this Lease, effective as of the date the Refusal Space is to be included in the Premises, on the same terms as this Lease except (a) the Basic Rent shall be the amount specified in the Refusal Notice, (b) the term for the
Refusal Space shall be that specified in the Refusal Notice, (c) Tenant shall lease the Refusal Space in an “AS-IS” condition, Landlord shall not be required to perform any work therein, and Landlord shall not provide to Tenant any
allowances other than those contained in the Third Party Offer (e.g., moving allowance, construction allowance, and the like) if any, and (d) other terms set forth in this Lease which are inconsistent with the terms of the Refusal Notice shall
be modified accordingly. Notwithstanding the foregoing, if the Refusal Notice includes space in excess of the Refusal Space, Tenant must exercise its right hereunder, if at all, as to all of the space contained in the Refusal Notice. If Tenant fails
or is unable to timely exercise its right hereunder, then such right shall lapse (it being understood that Tenant’s right under this Exhibit is a one-time right only), time being of the essence with respect to the exercise thereof, and Landlord
may lease all or a portion of the Refusal Space to third parties on such terms as Landlord may elect. Tenant may not exercise its rights under this Exhibit if an Event of Default exists or Tenant is not then occupying the entire Premises. For
purposes hereof, if an Refusal Notice is delivered for less than all of the Refusal Space but such notice provides for an expansion, right of first refusal, or other preferential right to lease some of the remaining portion of the Refusal Space,
then such remaining portion of the Refusal Space shall thereafter be excluded from the provisions of this Exhibit. In no event shall Landlord be obligated to pay a commission with respect to any space leased by Tenant under this Exhibit, and Tenant
and Landlord shall each indemnify the other against all costs, expenses, attorneys’ fees, and other liability for commissions or other compensation claimed by any broker or agent claiming the same by, through, or under the indemnifying party.

 Tenant’s rights under this Exhibit shall terminate if (a) this Lease or Tenant’s right to possession of the Premises is
terminated, (b) Tenant assigns any of its interest in this Lease or sublets any portion of the Premises, (c) Tenant fails timely to exercise its option as to any portion of the Refusal Space, or (d) less than two full calendar years
remain on the initial Term of this Lease.
