SEC. 1LEASED PREMISES: In consideration
of the mutual covenants as set forth herein, Lessor and Lessee hereby agree as follows:


 


A.Lessor hereby
leases to Lessee and Lessee hereby leases from Lessor for the rental and on the terms and conditions hereinafter set forth approximately
3,002 square feet of rentable area on the 2nd floor as indicated on the plan attached hereto as Exhibit “A” and known
as Suite 210 (the “Leased Premises”) in the office building located at 4710 Bellaire, Bellaire, Harris County, Texas
77401 (the “Building”). Facilities and areas of the Building that are intended and designated by Lessor from time to
time for the common, general and nonexclusive use of all tenants of the Building are defined as the “Common Areas”
which is part of the land described in Exhibit “A-1” (the “Land”). Lessor has the exclusive control over
and right to manage the Common Areas and Land. Lessor shall have the exclusive use and control over all other areas of the Building
and the property including, but not limited to, risers, horizontal and vertical shafts and telephone closets. Lessor reserves the
right at any time to, in its commercially reasonable discretion, relocate, vary and adjust the size of the various buildings, covenants,
automobile parking areas, Land and Common Areas.


 


B.Lessor also leases
to Lessee certain parking space in the garage on the terms and conditions set forth in Exhibit “B” attached hereto.
The total number of parking spaces for the property shall not decrease during the term of this lease.


 


C.The Leased Premises
shall be delivered to Lessee and Lessee shall accept same, in its current “AS IS, WHERE IS” condition subject
to the construction of leasehold improvements, if any, set forth and described on Exhibit “F” attached hereto and made
a part hereof for all purposes. Lessee acknowledges that no representations as to the repair of the Leased Premises or the Building,
nor promises to alter, remodel or improve the Leased Premises or the Building, have been made by Lessor, except as are expressly
set forth in this Lease Agreement.


 


SEC. 2TERM: Subject to and upon
the conditions set forth herein, or any exhibit or addendum hereto, the “Term” of this Lease Agreement shall be for
a period of sixty (60) months, beginning on the earlier of August 1, 2014 or upon substantial completion of the Leasehold Improvements
as set out in Exhibit “F” (“Commencement Date”) and shall end at midnight after the expiration of sixty
(60) months, unless sooner terminated or renewed and extended in accordance with the terms and conditions set forth herein (the
“Expiration Date”). This Lease Agreement shall be effective as of the Effective Date (as hereinafter defined) and in
the event Lessee or its agents, employees or contractors enter the Leased Premises prior to the Commencement Date, such entry shall
be subject to the terms and conditions of this Lease Agreement, except that the rent shall not commence to accrue as a result of
such entry until the date specified in Section 5 below. Notwithstanding any other provision of this Lease Agreement to the contrary,
if the Expiration Date would otherwise occur on a date other than the last day of a calendar month, then the Term shall be automatically
extended to include the last day of such calendar month, which shall become the Expiration Date.


 


SEC. 3USE: The Leased Premises
shall be used and occupied by Lessee solely as general office use and for no other purpose. The Leased Premises shall not be used
for any purpose which would tend to lower the character of the Building, or create unreasonable elevator loads or otherwise interfere
with standard Building operations. Lessee agrees specifically that no food, soft drink or other vending machine will be installed
within the Leased Premises without the prior written consent of Lessor, which consent shall not be unreasonably withheld if such
machine is for the exclusive use of Lessee, its employees and invitees.


 


SEC. 4SECURITY DEPOSIT: $7,319.88
payable on the Effective Date of this Lease Agreement (“Security Deposit”). Upon the occurrence of any event of default
by Lessee, Lessor may, from time to time, without prejudice to any other remedy, use the Security Deposit to the extent necessary
to make good any arrears of rent and any other damage, injury, expense or liability caused to Lessor by such event of default.
Any remaining balance of the Security Deposit shall be automatically and immediately returned by Lessor to Lessee upon termination
of this Lease Agreement within sixty (60) days after the termination of this Lease Agreement; provided, however, Lessor shall have
the right to retain and expend such remaining balance (a) to reimburse Lessor for any and all rentals or other sums due hereunder
that have not been paid in full by Lessee and/or (b) for cleaning and repairing the Leased Premises if Lessee shall fail to deliver
same at the termination of this Lease Agreement in a neat and clean condition and in as good a condition as existed at the date
of possession of same by Lessee, ordinary wear and tear only excepted. Lessee shall not be entitled to any interest on the Security
Deposit. The Security Deposit shall not be considered an advance payment of rental or a measure of Lessor's damages in case of
default by Lessee.


 






    	 



    	 



    

 


SEC. 5BASE RENT:  As part of
the consideration for the execution of this Lease Agreement, Lessee covenants and agrees and promises to pay as base rent monthly
installments in accordance with the rental schedule set forth below (the “Base Rent”) in legal tender of the United
States of America payable to Lessor at the Building management office (or such other address as may be designated by Lessor in
writing from time to time) in advance, without demand and without deduction, on the first day of each calendar month during the
Term hereof; provided, however, the first monthly payment of Base Rent shall be made on the Effective Date of this Lease Agreement.
Such Base Rent shall be subject to adjustments as hereinafter provided.


 


After the 5th
day of the month in which rent is due, rent shall be considered delinquent and Lessee shall be required to pay Lessor a sum equal
to five percent (5%) of any monthly rental required to be paid by Lessee to Lessor under the terms hereof. The covenants by Lessee
to pay rent under this Lease are independent of any other covenants of Lessor as set forth in this Lease. Lessee acknowledges that
Lessor’s failure to provide written invoices shall in no way serve to waive any of Lessee’s obligations to pay Base
Rental or Additional Monthly Rent owing under the terms of the Lease.


 





	 	Months 1	to	12	 	$6,504.33 per month
	 	Months 13	to 	24	 	$6,699.46 per month
	 	Months 25	to 	36	 	$6,899.60 per month
	 	Months 37	to 	48	 	$7,107.24 per month
	 	Months 49	to 	60	 	$7,319.88 per month













 


In addition to the
foregoing rent, Lessee agrees to pay to Lessor all charges for any services, goods or materials furnished by Lessor at Lessee's
request which are not required to be furnished by Lessor under this Lease Agreement within fifteen (15) days of the date on which
a written invoice is delivered. Lessee acknowledges that Lessor’s failure to provide such written invoices shall in no way
serve to waive any of Lessee’s obligation to pay any other amounts owing under the terms of the Lease. All past due installments
for all charges for any services, good, or materials furnished shall bear interest at the rate of eighteen percent (18%) per annum
or the highest lawful rate, whichever is less, from date due until paid; provided, however, in no event shall the rate of interest
hereunder exceed the maximum non-usurious rate of interest (hereinafter called the “Maximum Rate”) permitted by the
applicable laws of the State of Texas or the United States of America, and to the extent that the Maximum Rate is determined by
reference to the laws of the State of Texas, the Maximum Rate shall be the weekly ceiling (as defined and described in Chapter
303 of the Texas Finance Code, as amended) at the applicable time in effect.


 


SEC. 6ADJUSTMENT OF BASE RENT:
The Base Rent provided for herein includes a component applicable to Basic Cost (as hereinafter defined) equal, on a per annum
basis, to the actual Operating Expenses (defined below) of the Complex (defined below) for the calendar year 2014 (the “Base
Year”) per square foot of rentable area of office space in the Complex, such amount being hereinafter referred to as “Base
Operating Expense”.


 


A.“Basic
Cost” as said term is used herein shall consist of the Operating Expenses (defined below) of the Complex (defined below),
which shall be computed on the accrual basis. All Operating Expenses shall be determined in accordance with generally accepted
accounting principles, consistently applied. The term “Operating Expenses” as used herein shall mean all expenses,
costs and disbursements in connection with the ownership, operation, management, maintenance and repair of the Building, the Land,
related pedestrian walkways, landscaping, fountains, roadways and parking facilities, and such additional facilities to service
any of the foregoing in subsequent years as may be necessary or desirable in Lessor’s reasonable discretion (the Building,
the Land and said additional facilities being hereinafter sometimes referred to as the “Complex”), including but not
limited to the following:


 


		(1)	Wages and salaries of the dedicated on-site personnel of any management company engaged to manage
the Complex and of all employees engaged in the operation, security, cleaning and maintenance of the Complex, including customary
taxes, insurance and benefits relating thereto.



 


		(2)	All supplies and materials used in operation and maintenance of the Complex.



 


		(3)	Cost of all utilities for the Complex, including but not limited to the costs of water and power,
heating, lighting, air conditioning and ventilation.



 


		(4)	Cost of all janitorial service, maintenance and service agreements for the Leased Premises, Complex
and the equipment therein, including alarm service, Musak, window cleaning, janitorial service and elevator maintenance.



 


		(5)	Cost of all insurance relating to the Complex which Lessor may elect to obtain, including but not
limited to casualty and liability insurance applicable to the Complex and Lessor’s personal property used in connection therewith;
the amount of the deductible from any insurance proceeds paid to Lessor shall also constitute an Operating Expense.



 






    	 



    	 



    

 


		(6)	Accounting costs and audit fees attributable to Lessor's operation of the Complex, including without
limitation in connection with tax returns. The term “Real Estate Taxes” shall mean, all taxes and assessments and other
governmental charges (whether federal, state, county or municipal and whether they be by taxing districts or authorities presently
taxing the Leased Premises or by others subsequently created or otherwise) and any other taxes and improvement assessments attributable
to the Complex, or its operation or the revenues or rents received therefrom (whether directly or indirectly through the use of
a franchise, margin or other similar tax and whether or not such taxes allow for the deduction of expenses in calculating the base
amount on which the tax is levied) but excluding, however, federal and state taxes on income; provided, however, that if at any
time during the Term, new taxes, assessments, levies, impositions or charges are imposed on the rents received from the Complex
or the rents reserved herein or any part thereof (whether directly or indirectly through the use of a franchise, margin or other
similar tax), or the present method of taxation or assessment shall be so changed that the whole or any part of the taxes, assessments,
levies, impositions or charges now levied, assessed or imposed on real estate and the improvements thereof shall be discontinued
and as a substitute therefor, or in lieu of an increase to the tax rate thereof, taxes, assessments, levies, impositions or charges
shall be levied, assessed and/or imposed wholly or partially as a capital levy or otherwise on the rents received from the Complex
or the rents reserved herein or any part thereof (whether directly or indirectly through the use of a franchise, margin or similar
tax and whether or not such taxes allow for the deduction of expenses in calculating the base amount on which the tax is levied),
then such substitute or additional taxes, assessments, levies, impositions or charges, to the extent so levied, assessed or imposed,
shall be deemed to be included within Operating Expenses to the extent that such substitute or additional tax would be payable
if the Complex were the only property of the Lessor subject to such tax. It is agreed that Lessee will also be responsible for
ad valorem taxes on its personal property and on the value of leasehold improvements to the extent that the same exceed standard
building allowance. Notwithstanding anything contained herein to the contrary, Real Estate Taxes shall not include (A) penalties,
late fees and/or interest; (B) excise taxes or gross receipt taxes on Lessor’s gross or net rentals or other income; (C)
except as stated above, income, franchise, transfer, gift, estate, succession, inheritance, and capital stock taxes; (D) taxes

or information to any taxing authority or to comply with any requirement of any taxing authority; (G) increases in Real Estate
Taxes with respect to the Complex resulting from alterations, additions or improvements to the Complex (collectively, “Additions”),
except to the extent that such Additions are performed for the benefit of all tenants in the Complex or increase the rentable area
of the Complex in excess of the rentable area which exists as of the date of this Lease Agreement; (H) any increases in Real Estate
Taxes or assessments resulting from any finance or refinance of the Complex or change in ownership or control of the owner or lessor
of the Complex, or any part thereof, including, without limitation, a transfer of title, in whole or in part; (I) any item to the
extent otherwise included in Operating Expenses; (J) reserves for future Real Estate Taxes; and (K) any personal property taxes
attributable to sculptures, paintings or other objects of art, except for objects of art installed in the common areas of the Complex
pursuant to requirements of public authority.



 


		(7)	Cost of repairs and general maintenance excluding: i) capital repairs, except those capital expenditures
which serve to decrease operating expenses of the Building or are required by governmental legislation; ii) repairs and general
maintenance paid by proceeds of insurance or by Lessee or other third parties; and, iii) alterations attributable solely to tenants
of the Building other than Lessee.



 


		(8)	The property management fees incurred by Lessor (not to exceed four percent (4%) of the gross revenues
of the Complex).



 


B. Notwithstanding
anything contained herein to the contrary, Operating Expenses shall not include (i) except as expressly provided above, expenditures
classified as capital expenditures for federal income tax purposes; (ii) costs for which Lessor is entitled to specific reimbursement
by Lessee, by any other tenant of the Complex; (iii) leasing commissions; (iv) costs incurred by Lessor in connection with the

nature paid to any executive employees above property manager for the Building; (xvii) intentionally deleted; (xviii) federal income

C.In the event
that the Basic Cost of Lessor's operation of the Building during any calendar year of the term of this Lease Agreement shall exceed
the Base Operating Expense set out above, Lessee shall pay to Lessor as additional rent its pro rata share of the increase in such
Basic Cost for such year over the Base Operating Expense. Lessee's pro rata share shall be 4.1%.


  


D.All amounts which
may be due under this paragraph shall be due within thirty (30) days after Lessor submits to Lessee a bill or invoice therefor.
Lessor shall monitor Basic Cost for the Building throughout the Term hereof and prepare projections of the anticipated Basic Cost
for the Building for each calendar year during the Term hereof. At any time that such projection shall indicate that Basic Cost
shall exceed the Base Operating Expense, Lessor may commence monthly billings for the collection of the amount of the anticipated
excess. Lessor may submit to Lessee a bill or invoice each month for one-twelfth (1/12) of the amount of the excess of projected
or actual Basic Cost over Base Operating Expense for the calendar year in question, as same may be ascertained by Lessor to be
due by Lessee under this paragraph. The amount of the first such bill or invoice shall be determined by multiplying the monthly
amount due by the number of calendar months of the calendar year in question which have commenced as of the date of the bill or
invoice. In the event of such billing or invoicing procedure by Lessor, then Lessee shall be bound and obligated to pay such indicated
amount contemporaneously with required payment of rent hereunder on the first day of each calendar month, monthly in advance, for
each month in the Term of this Lease Agreement, in lawful money of the United States. Notwithstanding any other provision herein
to the contrary, it is agreed that if less than ninety-five percent (95%) of the Building is occupied during any calendar year
(including, but not limited to, the Base Year) or if less than ninety-five percent (95%) of the Building is not provided with Building
standard services during any calendar year, an adjustment shall be made in computing each component of the Basic Cost for that
year which varies with the rate of occupancy of the Building (such as, but not limited to, utility, management fees and janitorial)
so that the total Basic Cost shall be computed for such year and the Base Year as though the Building had been ninety-five percent
(95%) occupied during such year and as though ninety-five percent (95%) of the Building had been provided with Building standard
services during that year.


 


F.Within one hundred
fifty (150) days after the end of each calendar year during the Term, Lessor shall provide Lessee a statement (prepared in accordance
with generally accepted accounting practices) showing the amount properly payable by Lessee, as additional rent under this Section,
for the preceding calendar year, whereupon if Lessee shall have overpaid, Lessor shall refund to Lessee the amount of the excess
within (30) days of the date of such statement; but if Lessee shall have underpaid, Lessor shall invoice Lessee for the amount
of the underpayment and such underpayment shall be due within thirty (30) days after delivery of such statement. The provisions
of this paragraph shall survive the expiration or termination of this Lease Agreement. The Base Rent, additional rent and all other
sums of money that become due and payable under this Lease Agreement shall collectively be referred to as “Rent”.


 


G.Lessor shall, on request, make
available to Lessee during reasonable business hours any applicable financial records maintained by Lessor with respect to Operating
Expenses, and, as required, permit Lessee, with reasonable notice, to inspect all such records with respect to Operating Expenses,
provided such inspection is conducted pursuant to the following terms and conditions: (i) such inspection must be conducted by
Lessee’s employees or an independent accounting firm that is not being compensated by Lessee on a contingency fee basis;
(ii) such inspection must be commenced within one (1) year after Lessor notifies Lessee of Lessee’s share of Operating Expenses
and, once commenced, such inspection shall be completed in a diligent and expeditious manner; (iii) Lessee shall supply Lessor
with a copy of the result of the inspection within thirty (30) days after Lessee’s receipt of same; (iv) no inspection shall
be conducted if Lessee has previously conducted an inspection for the same time period and no more than one inspection may be conducted
per calendar year; (v) such inspection shall be conducted during normal business hours, at a mutually agreed upon time, at Lessor’s
business address or at such other location as Lessor normally keeps its books and records of such Operating Expenses; (vi) such
inspection shall be at Lessee’s sole cost and expense and any reasonable costs or expenses incurred by Lessor in providing
Lessee with the information required to perform such inspection, including, but not limited to, reasonable copying costs and delivery
fees shall be paid by Lessee to Lessor within thirty (30) days after receipt of an invoice from Lessor (provided, that, in the
event that such inspection reveals Lessor overstated Lessee’s share of Operating Expenses in an amount equal to or greater
than five percent (5%), Lessor shall pay to Lessee, within thirty (30) days after receipt of an invoice from Lessee, Lessee’s
costs incurred in the performance of said inspection, not to exceed the amount of the $750.00); (vii) any information obtained
by Lessee as a result of such inspection shall be held in strict confidence by Lessee and shall not be disseminated further except
to Lessee’s accountants, attorneys and lenders; (viii) no subtenant shall have any right to conduct an inspection and no
assignee shall conduct an inspection for any period during which such assignee was not in possession of the Leased Premises.


 


Lessor and Lessee hereby each acknowledge
and agree that they are knowledgeable and experienced in commercial transactions and further hereby acknowledge and agree that
the provisions of this Lease Agreement for determining Basic Cost are commercially reasonable and valid even though such methods
may not state precise mathematical formulae for determining such Basic Cost.


 






    	 



    	 



    

 


SEC. 7SERVICE AND UTILITIES: Lessor
will provide water at those common points of supply provided for drinking, toilet and lavatory purposes and with electricity for
ordinary office uses (not to include, however, data processing machines other than personal computers and related equipment that
consumes less than .25 kilowatts per hour at rated capacity or requires a voltage of 120 volts single phase, including air conditioning
costs therefor, large business machines and similar equipment of high electrical consumption characteristics); ballast and lamp
replacement for the Building's standard florescent lighting fixtures located in the Leased Premises; elevator service; janitorial
service on a five (5) day per week basis, all in the manner, at times and to the extent as are typical for similarly-classed office
buildings in the Bellaire, Texas submarket. Notwithstanding anything contained herein to the contrary, Lessee shall be responsible
for the cleaning and stocking of restroom supplies for any private restroom located within the Leased Premises. In the event that
Lessee requests Lessor to include private restroom cleaning and supplies, Lessor shall charge a monthly fee to be set from time
to time, currently at $150 per restroom per month. Lessor shall provide Lessee at least sixty (60) days' notice of any change in
the standard restroom cleaning and stocking rate and the giving of such notice shall be deemed an amendment to this Agreement and
Lessee shall thereafter pay the adjusted rent. Lessee will pay all telephone charges. Lessor agrees to furnish Lessee with refrigerated
water at those points of supply provided for general use of other tenants in the Building; heated and refrigerated air conditioning
in season to be provided during the hours of 6:45 a.m. to 6:00 p.m. on weekdays and at the written request of Lessee from 7:00
a.m. to 1:00 p.m. on Saturday, at temperatures and in amounts as are typical for similarly-classed office buildings in the Bellaire,
Texas submarket. Failure by Lessor to furnish any of the services and utilities listed above to any extent, or any cessation thereof,
due to failure of any public utility or other provider to furnish service to the Building, or any other cause beyond the reasonable
control of Lessor, shall not render Lessor liable in any respect for damages to either person or property, nor be construed as
an eviction of Lessee, nor work an abatement of Rent, nor relieve Lessee from fulfillment of any covenant or agreement hereof.
As used herein, the phrase “causes beyond the reasonable control of Lessor” shall include, without limitation, acts
of the public enemy, restraining of government, unavailability of materials, strikes, civil riots, floods, hurricanes, tornadoes,
earthquakes and other severe weather conditions or acts of God. Notwithstanding anything contained herein to the contrary, in the
event Lessee is prevented from operating its business from the Leased Premises because of the unavailability of any such service
for a period of ten (10) consecutive business days following Lessor’s receipt from Lessee of a written notice regarding such
unavailability, the restoration of which is within Lessor’s reasonable control and not a result of force majeure, then Lessee
shall be entitled to a reasonable abatement of Rent for each consecutive day (after such ten (10) business day period) that Lessee
is so prevented from using the Leased Premises. Additionally, in the event that Lessee is prevented from operating its business
out of the Leased Premises because of the unavailability of any such service for a period of sixty (60) consecutive days following
Lessor’s receipt from Lessee of a written notice regarding such unavailability, the restoration of which is within Lessor’s
reasonable control and not a result of force majeure, then Lessee shall be entitled to terminate the Lease Agreement upon written
notice to Lessor.


 


The obligation of Lessor
to provide the services set forth above shall be subject to governmental regulation thereof (i.e., rationing, temperature control,
etc.) and any such regulation that impairs Lessor’s ability to provide said services as herein stipulated shall not constitute
an event of default hereunder but rather providing the applicable services to the extent allowed pursuant to such regulations shall
be deemed to be full compliance with the obligations and agreements of Lessor hereunder.


 


Except as otherwise
provided herein, Lessor shall not be liable in damages or otherwise for failure, stoppage or interruption of any such service,
nor shall the same be construed as an eviction of Lessee, work an abatement of rent, or relieve Lessee from the operation of any
covenant or agreement; but in the event of any failure, stoppage or interruption thereof, Lessor shall use reasonable diligence
to restore service promptly. The work of the building janitor shall not be hindered by Lessee. Upon request of Lessee made in accordance
with the rules and regulations for the Building, Lessor will use its good faith efforts to furnish air conditioning and heating
at other times (that is, at times other than the times specified above), in which event Lessee shall reimburse Lessor for the actual
cost Lessor incurs, as such cost may be adjusted from time to time, for furnishing such services.


 


Lessee hereby acknowledges
and agrees that Lessor is obligated to provide only the services set forth above, and that Lessor, its agents and representatives,
have made no representations whatsoever of any additional services or amenities to be provided by Lessor now or in the future under
this Lease Agreement. Notwithstanding the foregoing, Lessee recognizes that Lessor may, at Lessor’s sole option, elect to
provide additional services or amenities for the tenants of the Building from time to time, and hereby agrees that Lessor’s
discontinuance of any provision of any such additional services or amenities shall not constitute a default of Lessor under this
Lease Agreement nor entitle Lessee to any abatement of or reduction in rent.


 


SEC. 8MAINTENANCE, REPAIRS AND USE:
Lessor shall provide for the cleaning and maintenance of the public portions of the Building including painting and landscaping
surrounding the Building. Unless otherwise expressly stipulated herein, Lessor shall not be required to make any improvements or
repairs of any kind or character on the Leased Premises during the Term of this Lease Agreement, except such repairs as may be
required by normal maintenance operations which shall include repairs to the exterior walls, corridors, windows, roof and other
structural elements and equipment of the Building (including but not limited to, the building standard HVAC unit(s) servicing the
Leased Premises) and such additional maintenance as may be necessary because of damages by persons other than Lessee, its agents,
employees, invitees or visitors. Lessor, in Lessor’s commercially reasonable discretion and subject to Exhibit B attached
hereto, shall have sole control over the parking of automobiles and other vehicles and shall designate parking areas and building
service areas.


 


Lessor, its officers,
agents and representatives, subject to any security regulations imposed by any governmental authority, shall have the right to
enter (upon reasonable prior notice (except in the event of an emergency or normal janitorial service) all parts of the Leased
Premises at all reasonable hours, and in a manner so as not to unreasonably disrupt Lessee’s operations in the Leased Premises
to inspect, clean, make repairs, alterations and additions to the Building or Leased Premises which it may deem necessary or desirable,
or to provide any service which it is obligated to furnish to Lessee, and Lessee shall not be entitled to any abatement or reduction
of rent by reason thereof.


 






    	 



    	 



    

 


Lessor may, at its
option and at the cost and expense of Lessee, repair or replace any damage or injury done to the Building or any part thereof not
covered by Lessor’s insurance and/or caused by the gross negligence or willful misconduct of Lessee, Lessee's agents, employees,
licensees, invitees or visitors; Lessee shall pay the cost thereof to Lessor on demand. Lessee further agrees to maintain and keep
the interior of the Leased Premises in good repair and condition at Lessee's expense. Lessee agrees not to commit or allow any
waste or damage to be committed on any portion of the Leased Premises, and at the termination of this Lease Agreement, by lapse
of time or otherwise, to deliver up the Leased Premises to Lessor in as good condition as on date of possession by Lessee, ordinary
wear and tear alone excepted, and upon such termination of this Lease, Lessor shall have the right to re-enter and resume possession
of the Leased Premises.


 


Lessee will not use,
occupy or permit the use or occupancy of the Leased Premises for any purpose which is directly or indirectly forbidden by law,
ordinance or governmental or municipal regulation or order, or which may be dangerous to life, limb or property; or permit the
maintenance of any public or private nuisance; or do or permit any other thing which may disturb the quiet enjoyment of any other
tenant of the Building; or keep any substance or carry on or permit any operation which might emit offensive odors or conditions
into other portions of the Building; or use any apparatus which might make undue noise or set up vibrations in the Building; or
permit anything to be done which would increase the fire and extended coverage insurance rate on the Building or contents and if
there is any increase in such rates by reason of acts of Lessee, then Lessee agrees to pay such increase promptly upon demand therefor
by Lessor. In the event Lessee fails to correct, cure or discontinue such prohibited or dangerous use following notice within the
applicable cure period set forth herein, such failure shall constitute an event of default by Lessee hereunder and Lessor shall
have all of its remedies as set forth in this Lease Agreement.


 


SEC. 9QUIET ENJOYMENT: Lessee,
on paying the said rent and performing the covenants herein agreed to be by it performed, shall and may peaceably and quietly have,
hold and enjoy the Leased Premises for the said Term.


 


Notwithstanding anything
herein to the contrary, Lessor hereby expressly reserves the right in its sole discretion to (i) temporarily or permanently change
the location of, close, block or otherwise alter any streets, driveways, entrances, corridors, doorways or walkways leading to
or providing access to the Complex or any part thereof or otherwise restrict the use of same provided such activities do not unreasonably
impair Lessee’s access to the Leased Premises, (ii) improve, remodel, add additional floors to or otherwise alter the Building,
(iii) construct, alter, remodel or repair one or more parking facilities (including garages) on the land upon which the Building
is located, and (iv) convey, transfer or dedicate portions of said land. The exercise of any of Lessor’s rights pursuant
to this Section 9, shall in no way reduce Lessee’s obligations under this Lease Agreement or impose any liability on Lessor
and it is agreed that Lessor shall not incur any liability whatsoever to Lessee as a consequence thereof and such activities shall
not be deemed to be a breach of any of Lessor’s obligations hereunder. Lessor agrees to exercise good faith in notifying
Lessee within a reasonable time in advance of any alterations, modifications or other actions of Lessor under this Section 9. Any
diminution or shutting off of light, air or view by any structure which is now or may hereafter be effected on lands adjacent to
the Building shall in no way affect this Lease Agreement or impose any liability on Lessor. Noise, dust or vibration or other incidents
to new construction of improvements on lands adjacent to the Building, whether or not owned by Lessor, or on the land upon which
the Building is located shall in no way affect this Lease Agreement or impose any liability on Lessor. Lessee agrees to cooperate
with Lessor in furtherance of Lessor’s exercise of any of the rights specified in this Section 9.


 


SEC. 10ALTERATIONS: Except for
Non-Material Alterations (as defined herein), Lessee shall provide Lessor with thirty (30) days advance written notice providing
Lessor with copies of plans and specifications for such alterations and names of the contractors Lessee intends to use, however,
Lessor reserves the right to change, in its commercially reasonable discretion, the Contractor to be used to make the alterations.
Notwithstanding anything to the contrary contained herein, Lessee shall have the right to make alterations or physical additions
to the Leased Premises that (i) are non-structural and do not materially adversely affect any Building systems (i.e. HVAC,
sprinkler main or riser systems) or improvements, (ii) are not visible from the exterior of the Leased Premises, and (iii) the
cost of which does not exceed $20,000, ("Non-Material Alterations") without the need for Lessor's prior consent. Prior
to commencement of construction of the alterations (other than Non-Material Alterations), Lessee shall deliver to Lessor a building
permit, copy of the executed construction contract, evidence of contractor and subcontractor’s insurance for such period
and in such amounts as Lessor reasonably requires. Lessee shall pay to Lessor upon demand a review fee in the amount of Lessor’s
actual costs incurred to compensate Lessor for the cost of review and approval of the plans and specifications and for additional
administrative costs incurred in monitoring the construction of the alterations (other than Non-Material Alterations). Lessee shall
deliver to Lessor a copy of the “as-built” plans and specifications for all alterations or physical additions so made
in or to the Leased Premises (other than Non-Material Alterations), and shall reimburse Lessor for the commercially reasonable
cost incurred by Lessor to update its current architectural plans for the Building.


 


Lessee shall indemnify,
defend (with counsel reasonably acceptable to Lessor) and hold harmless the Lessor from and against all costs (including attorneys’
fees and costs of suit), losses, liabilities, or causes of action arising out of or relating to any alterations, additions or improvements
made by Lessee to the Leased Premises, including but not limited to any mechanics’ or materialmen’s liens asserted
in connection therewith.


 


Lessee shall not be
deemed to be the agent or representative of Lessor in making any such alterations, physical additions or improvements to the Leased
Premises, and shall have no right, power or authority to encumber any interest in the Complex in connection therewith other than
Lessee’s leasehold estate under this Lease Agreement. However, should any mechanics’ or other liens be filed against
any portion of the Complex or any interest therein (other than Lessee’s leasehold estate hereunder) by reason of Lessee’s
acts or omissions or because of a claim against Lessee or its contractors, Lessee shall cause the same to be canceled or discharged
of record by bond or otherwise within ten (10) business days after notice by Lessor. If Lessee shall fail to cancel or discharge
said lien or liens, within said ten (10) business day period, which failure shall be deemed to be a default hereunder, Lessor may,
at its sole option and in addition to any other remedy of Lessor hereunder, cancel or discharge the same and upon Lessor’s
demand, Lessee shall promptly reimburse Lessor for all reasonable costs incurred in canceling or discharging such lien or liens.


 






    	 



    	 



    

 





Lessee shall cause
all alterations, physical additions, and improvements (including fixtures), constructed or installed in the Leased Premises by
or on behalf of Lessee to comply with all applicable governmental codes, ordinances, rules, regulations and laws. Lessee acknowledges
and agrees that neither Lessor’s review and approval of Lessee’s plans and specifications nor its observation or supervision
of the construction or installation thereof shall constitute any warranty or agreement by Lessor that same comply with such codes,
ordinances, rules, regulations and laws.


 


Lessee shall be wholly
responsible for any accommodations or alterations that are required by applicable governmental codes, ordinances, rules, regulations
and laws to be made to the Leased Premises to accommodate disabled employees and customers of Lessee, including, without limitation,
compliance with the Americans with Disabilities Act (42 U.S.C. §§ 12101 et seq.) and the Texas Architectural Barriers
Act (Tex.Rev.Civ.Stat. Art 9201) (collectively, the “Accommodation Laws”). Except to the extent provided below, Lessor
shall be responsible for making all accommodations and alterations to the Common Areas of the Building necessary to comply with
the Accommodation Laws.


 


SEC. 11FURNITURE, FIXTURES AND PERSONAL
PROPERTY: Lessee may remove its trade fixtures, office supplies and movable office furniture and equipment not attached to
the Building provided: (a) such removal is made prior to the termination of the term of this Lease Agreement; (b) Lessee is not
in default of any obligation or covenant under this Lease Agreement at the time of such removal; and (c) Lessee promptly repairs
all reasonable damage caused by such removal. All other property at the Leased Premises and any alterations or additions to the
Leased Premises (including wall-to-wall carpeting, paneling or other wall covering) and any other article attached or affixed to
the floor, wall or ceiling of the Leased Premises shall become the property of Lessor and shall remain upon and be surrendered
with the Leased Premises as a part thereof at the termination of the Lease Agreement by lapse of time or otherwise, Lessee hereby
waiving all rights to any payment or compensation therefor. If, however, Lessor so requests in writing within sixty (60) days prior
to the termination of this Lease Agreement, Lessee will, prior to termination of this Lease Agreement, remove any and all alterations,
additions, fixtures, equipment and property placed or installed by Lessee in the Leased Premises and will repair any reasonable
damage caused by such removal.


 


Lessee shall, at Lessee’s
expense, remove all of its telecommunications equipment, which was originally installed by Lessee, including but not limited to,
switches, cabling and wiring, racks and boards, whether they are located within the Leased Premises or in the Common Areas. If
Lessee does not complete all removals prior to the termination of this Lease Agreement, Lessor may remove such items (or contract
for the removal of such items) and Lessee shall reimburse Lessor upon demand for the costs incurred by Lessor in connection therewith.


 


SEC. 12SUBLETTING AND ASSIGNMENT:


 


A.In the event
Lessee should desire to assign this Lease Agreement or sublet the Leased Premises or any part thereof or allow same to be used
or occupied by others, Lessee shall give Lessor written notice (which shall specify the duration of said desired sublease or assignment,
the date same is to occur, the exact location of the space affected thereby, the proposed rentals on a square foot basis chargeable
thereunder and sufficient information of the proposed sublessee or assignee regarding its financial condition and business operations)
of such desire at least thirty (30) days in advance of the date on which Lessee desires to make such assignment or sublease or
allow such a use or occupancy. Lessor shall then have a period of twenty (20) days following receipt of such notice within which
to notify Lessee in writing that Lessor elects:


 


		(1)	To refuse to permit Lessee to assign this Lease Agreement or sublet such space, and in such case
this Lease Agreement shall continue in full force and effect in accordance with the terms and conditions hereof; or



 


		(2)	To terminate this Lease Agreement as to the space so affected as of the date so specified by Lessee
in which event Lessee shall be relieved of all obligations hereunder as to such space arising from and after such date; or



 


		(3)	To permit Lessee to assign this Lease Agreement or sublet such space for the duration specified
in such notice, subject to Lessor’s subsequent written approval of the proposed assignee or sublessee, which approval shall
not be unreasonably withheld or unduly delayed if (a) the nature and character of the proposed assignee or sublessee, its business
and activities and intended use of the Leased Premises are in Lessor’s reasonable judgment consistent with the current standards
of the Building and the floor or floors on which the Leased Premises are located, (b) neither the proposed assignee or sublessee
(nor any party which, directly or indirectly, controls or is controlled by or is under common control with the proposed assignee
or sublessee) is a department, representative or agency of any governmental body or currently an occupant of any part of the Building
or a party with whom Lessor is then negotiating to lease space in the Building or in any adjacent Building owned by Lessor, (c)
the form and substance of the proposed sublease or instrument of assignment is acceptable to Lessor (which acceptance by Lessor
shall not be unreasonably withheld) and is expressly subject to all of the terms and provisions of this Lease Agreement and to
any matters to which this Lease Agreement is subject, (d) the proposed occupancy would not (1) increase the office cleaning requirements,
(2) impose an extra burden upon the services to be supplied by Lessor to Lessee hereunder, (3) violate the current rules and regulations
of the Building, (4) violate the provisions of any other leases of tenants in the Building or (5) cause alterations or additions
to be made to the Building (excluding the Leased Premises), (e) Lessee enters into a written agreement with Lessor whereby it is
agreed that any profit realized by Lessee as a result of said sublease or assignment and any and all sums and other considerations
of whatsoever nature paid to Lessee by the assignee or sublessee for or by reason of such assignment or sublease, including, but
not limited to, sums paid for the sale of Lessee’s fixtures, leasehold improvements, equipment, furniture, furnishings or
other personal property (that is, after deducting and giving Lessee credit for Lessee’s reasonable costs directly associated
therewith, including reasonable brokerage fees and the reasonable cost of remodeling or otherwise improving the Leased Premises
for said assignee or sublessee but excluding any free rentals or the like offered to any such sublessee or assignee) shall be payable
to Lessor as it accrues as additional rent hereunder, and (f) the granting of such consent will not constitute a default under
any other agreement to which Lessor is a party or by which Lessor is bound and (g) the creditworthiness of the proposed assignee
or sublessee is acceptable to Lessor, in Lessor’s commercially reasonable discretion.



 






    	 



    	 



    

 


B.No assignment
or subletting by Lessee shall be effective unless Lessee shall execute, have acknowledged and deliver to Lessor, and cause each
sublessee or assignee to execute, have acknowledged and deliver to Lessor, an instrument in form and substance acceptable to Lessor
in which (i) such sublessee or assignee adopts this Lease Agreement and assumes and agrees to perform jointly and severally with
Lessee, all of the obligations of Lessee under this Lease Agreement, as to the space transferred to it, (ii) Lessee and such sublessee
or assignee agree to provide to Lessor, at their expense, direct access from a public corridor in the Building to the transferred
space, (iii) such sublessee or assignee agrees to use and occupy the transferred space solely for the purpose specified in Section
3 and otherwise in strict accordance with this Lease Agreement and (iv) Lessee acknowledges and agrees that, notwithstanding such
subletting or assignment, Lessee remains directly and primarily liable for the performance of all the obligations of Lessee hereunder
(including, without limitation, the obligation to pay rent), and Lessor shall be permitted to enforce this Lease Agreement against
Lessee or such sublessee or assignee, or both, without prior demand upon or proceeding in any way against any other persons. Lessee
shall, upon demand, reimburse Lessor for all reasonable expenses incurred by Lessor in connection with a request made by Lessee
pursuant to this Section 12, including, without limitation, any investigations as to the acceptability of the proposed assignee
or sublessee and all legal costs reasonably incurred in connection with the granting of any requested consent.


 


C.Any consent by
Lessor to a particular assignment or sublease shall not constitute Lessor’s consent to any other or subsequent assignment
or sublease, and any proposed sublease or assignment by any assignee or sublessee shall be subject to the provisions of this Section
12 as if it were a proposed sublease or assignment by Lessee. The prohibition against an assignment or sublease described in this
Section 12 shall be deemed to include a prohibition against (i) Lessee’s mortgaging or otherwise encumbering its leasehold
estate, and (ii) permitting the use or occupancy of the Leased Premises, or any part thereof, by anyone other than Lessee, each
of which shall be ineffective and void and shall constitute an event of default under this Lease Agreement unless consented to
by Lessor in writing in advance. Notwithstanding any of the other terms of this Section 12, Lessee may transfer all or part of
its interest in this Lease Agreement or all or part of the Leased Premises (a “Permitted Transfer”) to the following
types of entities (a “Permitted Transferee”) without the written consent of Lessor:


 


(1)any
person or entity which, directly or indirectly, through one or more intermediaries, controls, is controlled by, or is under common
control of Lessee;


 


(2)any
corporation, limited partnership, limited liability partnership, limited liability company or other business entity in which or
with which Lessee, 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) Lessee’s obligations hereunder are assumed by the
entity surviving such merger or created by such consolidation; and (B) the Tangible Net Worth (as hereinafter defined) of the surviving
or created entity is not less than the Tangible Net Worth of Tenant as of the date hereof; or


 


(3)any
corporation, limited partnership, limited liability partnership, limited liability company or other business entity acquiring all
or substantially all of Lessee’s assets if such entity’s Tangible Net Worth after such acquisition is not less than
the Tangible Net Worth of Tenant as of the date hereof.


 


Lessee shall promptly notify Lessor of
any such Permitted Transfer. Lessee shall remain liable for the performance of all of the obligations of Lessee hereunder, or if
Lessee no longer exists because of a merger, consolidation, or acquisition, the surviving or acquiring entity shall expressly assume
in writing the obligations of Lessee hereunder. Additionally, the Permitted Transferee shall comply with all of the terms and conditions
of this Lease Agreement, including the Permitted Use, and the use of the Leased Premises by the Permitted Transferee may not violate
any other agreements affecting the Leased Premises, the Building, the Complex, Lessor or other tenants of the Building or Complex.
No later than thirty (30) days after the effective date of any Permitted Transfer, Lessee agrees to furnish Lessor with (A) copies
of the instrument effecting any of the foregoing transfers, (B) documentation establishing Lessee’s satisfaction of the requirements
set forth above applicable to any such transfer, and (C) evidence of insurance as required under this Lease Agreement with respect
to the Permitted Transferee. The occurrence of a Permitted Transfer shall not waive Lessor’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, excluding, however, from the determination of total assets all assets
which would be classified as intangible assets under generally accepted accounting principles 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 12.


 






    	 



    	 



    

 


D.Should Lessee
request of Lessor the right to assign or sublet, Lessee agrees to pay Lessor Seven Hundred Fifty and No/100 Dollars ($750.00) as
an administration fee, payable with the request.


 


SEC. 13FIRE AND CASUALTY:


 


A.In the event
of a fire or other casualty in the Leased Premises, Lessee shall immediately give notice thereof to Lessor. If the Leased Premises
shall be partially destroyed by fire or other casualty so as to render the Leased Premises untenantable in whole or in part, Rent
shall abate thereafter as to the portion of the Leased Premises rendered untenantable until such time as the Leased Premises are
made tenantable as reasonably determined by Lessor and Lessor agrees to commence and prosecute such repair work promptly and with
all due diligence; provided, however, in the event such destruction (i) results in total or substantial damages to or destruction
of the Building and Lessor shall decide not to rebuild or (ii) results in the Leased Premises being untenantable in whole or in
substantial part and the reasonable estimation of a responsible contractor selected by Lessor as to the amount of time necessary
to rebuild or restore such destruction to the Leased Premises and all other portions of the Building exceeds eight (8) months from
the time such work is commenced, then in either event, Lessor or Lessee shall have a right to terminate this Lease Agreement effective
as of the date of casualty or destruction, and upon such termination, all Rent owed up to the time of such destruction or termination
shall be paid by Lessee. Subject to reasonable delays for insurance adjustments, either party shall give written notice of its
decision, estimates or elections under this Section 13 within sixty (60) days after any such damage or destruction (the “Damage
Notice”). In the event this Lease Agreement is not terminated by either Lessor or Lessee, as provided above, and the actual
time period of restoration of the Leased Premises exceeds eight (8) months, as the same may be extended by Force Majeure or delays
caused by Lessee, Lessee may terminate this Lease Agreement by delivering written notice to Lessor within ten (10) days following
the expiration of such eight (8) month period (as same may be extended as set forth above) and prior to the date upon which Lessor
substantially completes such restoration. Such termination shall be effective as of the date specified in Lessee’s termination
notice, as if such date were the date fixed for the expiration of the Term.


 


B.Notwithstanding
anything in this Lease Agreement to the contrary, if the Leased Premises are damaged by fire or other casualty resulting from the
fault or negligence of Lessee, or the agents, employees, licensees or invitees of Lessee, such damage shall be repaired by and
at the expense of Lessee under the direction and supervision of Lessor, and rent shall continue without abatement.


 


C.Notwithstanding
anything contained in this Section 13, in no event shall Lessor be required to expend more to reconstruct, restore and repair the
Building than the amount actually received by Lessor from the proceeds of the property insurance carried by Lessor and Lessor shall
have no duty to repair or restore any portion of any alterations, additions, installation or improvements in the Leased Premises
or the decorations thereto except to the extent that the proceeds of the insurance carried by Lessee are timely received by Lessor.
If Lessee desires any other additional repairs or restoration, and if Lessor consents thereto, it shall be done at Lessee’s
sole cost and expense subject to all of the applicable provisions of this Lease Agreement. Lessee acknowledges that Lessor shall
be entitled to the full proceeds of any insurance coverage whether carried by Lessor or Lessee, for damage to any alterations,
addition, installation, improvements or decorations which would become the Lessor’s property upon the termination of this
Lease Agreement.


 


SEC. 14CONDEMNATION:  If all
of the Complex is taken or condemned, or acquired under threat of condemnation, by or at the direction of any governmental authority
(a “Taking” or “Taken”, as the context requires), or if so much of the Complex is Taken that, in Lessor’s
opinion, the remainder cannot be restored to an economically viable, quality office building, or if the awards payable to Lessor
as a result of any Taking are, in Lessor’s opinion, inadequate to restore the remainder to an economically viable, quality
office building, Lessor may, at its election, exercisable by the giving of written notice to Lessee within thirty (30) days after
the date of the Taking, terminate this Lease Agreement as of the date of the Taking or the date Lessee is deprived of possession
of the Leased Premises (whichever is later). If this Lease Agreement is not terminated as a result of a Taking, Lessor shall restore
the Leased Premises remaining after the Taking to the condition existing as of the Commencement Date. Following the Taking and
through the period of restoration, Rent shall be abated to the extent the Leased Premises are rendered un-tenantable and, after
the period of restoration, Rent and Lessee’s pro rata share shall be reduced in the proportion that the area of the Leased
Premises Taken or otherwise rendered un-tenantable bears to the area of the Leased Premises just prior to the Taking. All awards,
proceeds, compensation or other payments from or with respect to any Taking of the Complex or any portion thereof shall belong
to Lessor, Lessee hereby assigning to Lessor all of its right, title, interest and claim to same. Lessee shall have the right to
assert a claim for and recover from the condemning authority, but not from Lessor, such compensation as may be awarded on account
of Lessee’s moving and relocation expenses, and depreciation to and loss of Lessee’s movable personal property. Additionally,
if any part of the Building or Complex is Taken, and such Taking will prevent Lessee from conducting on a permanent basis its business
in the Leased Premises in a manner reasonably comparable to that conducted immediately before such Taking, then Lessee may terminate
this Lease Agreement as of the date of such Taking by giving written notice to Lessor within thirty (30) days after the Taking,
and Rent shall be apportioned as of the date of such Taking. In the event Lessee does not terminate this Lease Agreement, then
Rent shall be abated on a reasonable basis as to that portion of the Leased Premises rendered untenantable by the Taking.


 






    	 



    	 



    

 


SEC. 15DEFAULT BY LESSEE: The
occurrence of any one or more of the following events shall be deemed to be an event of default by Lessee under this Lease Agreement:


 


A.Lessee shall
fail to pay when due Rent under the terms of this Lease Agreement within five (5) days following Lessee’s receipt of written
notice from Lessor (provided, however, that Lessor shall not be required to deliver such notice with regards to Base Rent more
than twice in a calendar year, after which the failure of Lessee to pay Base Rent shall be an event of default without the need
for Lessor to send written notice), or


 


B.Lessee shall
create, cause or permit a hazardous condition in violation of this Lease Agreement and the same is not cured by Lessee within twenty
(20) days after written notice to Lessee, or


 


C.The interest
of Lessee in this Lease Agreement shall be levied on or taken under execution or other legal process, or if any voluntary petition
in bankruptcy or for corporate reorganization or any similar relief shall be filed by Lessee, or if any involuntary petition in
bankruptcy shall be filed against Lessee under any federal or state bankruptcy or insolvency act and shall not have been dismissed
within thirty (30) days from the filing thereof, or


 


D.A receiver shall
be appointed for Lessee or any of the property of Lessee by any court and such receiver shall not have been dismissed within thirty
(30) days from the date of his appointment, or if Lessee shall make an assignment for the benefit of creditors, or if Lessee shall
admit in writing Lessee's inability to meet Lessee's debts as they mature, or


 


E.Lessee shall
assign this Lease Agreement or sublet all or any part of the Leased Premises without the prior written consent of Lessor in accordance
with Section 12, or


 


F.Lessee shall
fail to observe or perform any of the other covenants or conditions in this Lease Agreement which Lessee is required to observe
and perform and such failure shall continue for thirty (30) days after written notice to Lessee; provided, however, if the nature
of the default is such that it cannot be cured within the thirty (30)-day period, Lessee shall have so long as necessary to cure
such default, provided Lessee undertakes such curative action within the thirty (30)-day period and diligently and continuously
proceeds with such curative action up to an additional sixty (60) day period.


 


Lessor shall be in default under this Lease
Agreement if Lessor fails to fulfill or perform, in whole or in part, any of its obligations under this Lease Agreement and such
failure or non-performance shall continue for a period of thirty (30) days after written notice thereof has been given by Lessee
to Lessor; provided, however, if the nature of the default is such that it cannot be cured within the thirty (30)-day period, Lessor
shall have so long as necessary to cure such default, provided Lessor undertakes such curative action within the thirty (30)-day
period and diligently and continuously proceeds with such curative action.


 


SEC. 16REMEDIES OF LESSOR: Upon
any event of default, Lessor may exercise any one or more of the following described remedies, in addition to all other rights
and remedies provided at law or in equity:


 


A.Terminate this
Lease Agreement by written notice to Lessee and forthwith repossess the Leased Premises and be entitled to recover forthwith as
damages a sum of money equal to the total of (i) the cost of recovering the Leased Premises (including attorneys’ fees and
costs of suit), (ii) the cost of removing and storing any personal property, (iii) the unpaid Rent earned at the time of termination,
plus interest thereon at the rate described in Section 5, (iv) the present value (discounted at the rate of eight percent (8%)
per annum) of the balance of the Rent for the remainder of the Term less the present value (discounted at the same rate) of the
fair market rental value of the Leased Premises for said period, taking into account the period of time the Leased Premises will
remain vacant until a new tenant is obtained, and the cost to prepare the Leased Premises for occupancy and the other costs (such
as leasing commissions, tenant improvement allowances and attorneys’ fees) to be incurred by Lessor in connection therewith,
and (v) any other sum of money and damages owed by Lessee to Lessor under this Lease Agreement.


 


B.Terminate Lessee’s
right of possession (but not this Lease Agreement) and may repossess the Leased Premises by forcible detainer suit or otherwise,
without thereby releasing Lessee from any liability hereunder and without demand or notice of any kind to Lessee and without terminating
this Lease Agreement. Lessor shall use reasonable efforts under the circumstances to relet the Leased Premises on such terms and
conditions as Lessor in its sole discretion may determine (including a term different than the Term, rental concessions, alterations
and repair of the Leased Premises); provided, however, Lessor hereby reserves the right (i) to lease any other comparable space
available in the Building or in any adjacent building owned by Lessor prior to offering the Leased Premises for lease, and (ii)
to refuse to lease the Leased Premises to any potential tenant which does not meet Lessor’s standards and criteria for leasing
other comparable space in the Building. Lessor shall not be liable, nor shall Lessee’s obligations hereunder be diminished
because of, Lessor’s failure or refusal to relet the Leased Premises or collect rent due in respect of such reletting. For
the purpose of such reletting Lessor shall have the right to decorate or to make any repairs, changes, alterations or additions
in or to the Leased Premises as may be reasonably necessary or desirable. In the event that (i) Lessor shall fail or refuse to
relet the Leased Premises, or (ii) the Leased Premises are relet and a sufficient sum shall not be realized from such reletting
(after first deducting therefrom, for retention by Lessor, the unpaid Rent due hereunder earned but unpaid at the time of reletting
plus interest thereon at the rate specified in Section 5, the cost of recovering possession (including attorneys’ fees and
costs of suit), all of the costs and expenses of such decorations, repairs, changes, alterations and additions, the expense of
such reletting and the cost of collection of the rent accruing therefrom) to satisfy the Rent, then Lessee shall pay to Lessor
as damages a sum equal to the amount of such deficiency. Any such payments due Lessor shall be made upon demand therefor from time
to time and Lessee agrees that Lessor may file suit to recover any sums falling due under the terms of this Section 16 from time
to time. No delivery to or recovery by Lessor of any portion due Lessor hereunder shall be any defense in any action to recover
any amount not theretofore reduced to judgment in favor of Lessor, nor shall such reletting be construed as an election on the
part of Lessor to terminate this Lease Agreement unless a written notice of such intention be given to Lessee by Lessor. Notwithstanding
any such termination of Lessee’s right of possession of the Leased Premises, Lessor may at any time thereafter elect to terminate
this Lease Agreement. In any proceedings to enforce this Lease Agreement under this Section 16, Lessor shall be presumed to have
used its reasonable efforts to relet the Leased Premises, and Lessee shall bear the burden of proof to establish that such reasonable
efforts were not used.


 






    	 



    	 



    

 


C.Alter any and
all locks and other security devices at the Leased Premises, and if it does so Lessor shall not be required to provide a new key
or other access right to Lessee unless Lessee has cured all events of default; provided, however, that in any such instance, during
Lessor’s normal business hours and at the convenience of Lessor, and upon the written request of Lessee accompanied by such
written waivers and releases as Lessor may require, Lessor will escort Lessee or its authorized personnel to the Leased Premises
to retrieve any personal belongings or other property of Lessee not subject to the Lessor’s lien or security interest described
in Section 17. The provisions of this Section 16.C are intended to override and control any conflicting provisions of the Texas
Property Code.


 


D.All agreements
and provisions to be performed by Lessee under any of the terms of this Lease Agreement shall be at Lessee’s sole cost and
expense and without any abatement of Rent. If Lessee shall fail to pay any sum of money, other than Base Rent, required to be paid
by it hereunder or shall fail to cure any default and such failure shall continue for thirty (30) days after notice thereof by
Lessor, then Lessor may, but shall not be obligated so to do, and without waiving or releasing Lessee from any obligations, make
any such payment or perform any such act on Lessee’s part. All sums so paid by Lessor and all costs incurred by Lessor in
taking such action shall be deemed Additional Rent hereunder and shall be paid to Lessor on demand, and Lessor shall have (in addition
to all other rights and remedies of Lessor) the same rights and remedies in the event of the non-payment thereof by Lessee as in
the case of default by Lessee in the payment of Rent.


 


E.All property
removed from the Leased Premises by Lessor pursuant to any provisions of this Lease Agreement or of law may be handled, removed
or stored by Lessor at the cost and expense of Lessee, and Lessor shall in no event be responsible for the value, preservation
or safekeeping thereof. Lessee shall pay Lessor for all expenses incurred by Lessor in such removal and storage charges against
such property so long as the same shall be in Lessor’s possession or under Lessor’s control. All property not removed
from the Leased Premises or retaken from storage by Lessee within thirty (30) days after the end of the Term, however terminated,
or within thirty (30) days after notice to remove same by Lessor shall, at Lessor’s election, be conclusively deemed to have
been conveyed by Lessee to Lessor as by bill of sale without further payment or credit by Lessor to Lessee.


 


F.In connection
with the exercise by Lessor of its rights and remedies in respect of any event of default on the part of Lessee, to the extent
(but no further) that Lessor is required by applicable Texas law to mitigate damages, or to use efforts to do so, and such requirement
cannot be lawfully and effectively waived (it being the intention of Lessor and Lessee that such requirements be and are hereby
WAIVED to the maximum extent permitted by applicable law), Lessee agrees in favor of Lessor that Lessor shall not be deemed to
have failed to mitigate damages, or to have used the efforts required by law to do so, because:


 


		(1)	Lessor leases other space in the Building which is vacant prior to re-letting the Leased Premises;



 


		(2)	Lessor refuses to relet the Leased Premises to any affiliate of Lessee, or any principal of Lessee,
or any affiliate of such principal (for purposes of this Lease, "affiliate" shall mean and refer to any person or entity
controlling, under common control with, or controlled by, the party in question);



 


		(3)	Lessor refuses to relet the Leased Premises to any person or entity whose creditworthiness Lessor
in good faith deems unacceptable;



 


		(4)	Lessor refuses to relet the Leased Premises to any person or entity because the use proposed to
be made of the Leased Premises by such prospective tenant is not of a type and nature consistent with that of the other tenants
in the Building as of the date Lessee defaults under this Lease Agreement, or because such use would, in the good faith opinion
of Lessor, impose unreasonable or excessive demands upon the Building;



 


		(5)	Lessor refuses to relet the Leased Premises to any person or entity, or any affiliate of such person
or entity, who has been engaged in litigation with, or who has threatened litigation against, Lessor or any of its affiliates,
or whom Lessor in good faith deems to be unreasonably or excessively litigious;



 


		(6)	Lessor refuses to relet the Leased Premises because the tenant or the terms and provisions of the
proposed lease are not approved by the holders of any liens or security interests in the Building or any part thereof, or would
cause Lessor to breach or be in default of, or to be unable to perform any of its covenants under, any agreements between Lessor
and any third party;



 






    	 



    	 



    

 


		(7)	Lessor refuses to relet the Leased Premises because the proposed tenant is unwilling to execute
and deliver Lessor’s standard lease form without substantial tenant-oriented modifications or such tenant requires improvements
to the Leased Premises to be paid at Lessor’s cost and expense; or



 


 


		(8)	Lessor refuses to relet the Leased Premises to a person or entity whose character or reputation,
or the nature of whose business, Lessor in good faith deems unacceptable;



 


and it is further agreed that each and
all of the grounds for refusal set forth in clauses (1) through (8) above, both inclusive, of this sentence are reasonable grounds
for Lessor's refusal to relet the Leased Premises, or (as to all other provisions of this Lease Agreement) for Lessor's refusal
to issue any approval, or take any other action, of any nature whatsoever under this Lease Agreement. In the event the waiver set
forth in this Section 16.E shall be ineffective, Lessee further agrees in favor of Lessor, to the maximum extent to which it may
lawfully and effectively do so, that the following efforts to mitigate damages if made by Lessor (and without obligating Lessor
to render such efforts) shall be conclusively deemed reasonable, and that Lessor shall be conclusively deemed to have used the
efforts to mitigate damages required by applicable law if: Lessor places the Leased Premises on its inventory of available space
in the Building; Lessor makes such inventory available to brokers who request same; and Lessor shows the Leased Premises to prospective
tenants (or their brokers) who request to see it.


 


SEC. 17HOLD HARMLESS: INTENTIONALLY
DELETED.


 


SEC. 18LIEN FOR RENT: To secure
payment of all rent due and to become due hereunder, and the faithful performance of all the other covenants of the Lease Agreement
required to be performed by Lessee, Lessee hereby gives to Lessor an express contract lien on and security interest in and to all
property, chattels or merchandise which may be placed in the Leased Premises and also upon all proceeds of any insurance which
may accrue to Lessee by reason of damage to or destruction of such property. All exemption laws are hereby waived by Lessee.
This lien and security interest are given in addition to Lessor's statutory lien(s) and shall be cumulative thereto. This lien
and security interest may be foreclosed with or without Court proceedings, by public or private sale, with at least five (5) days
written notice to Lessee and Lessor shall have the right to become purchaser, upon being the highest bidder at such sale with the
proceeds from any sale being credited towards any outstanding amounts due under this Lease Agreement. Upon request of Lessor, Lessee
agrees to execute Uniform Commercial Code financing statements relating to the aforesaid security interest.


 


SEC. 19NON-WAIVER: Neither acceptance
of rent by Lessor nor failure by Lessee, whether singular or repetitive, shall constitute a waiver of any of Lessor's rights hereunder.
Waiver by Lessor of any right for any default of Lessee shall not constitute a waiver of any right for either a subsequent default
of the same obligation or any other default. No act or thing done by Lessor or its agent shall be deemed to be an acceptance or
surrender of the Leased Premises and no agreement to accept a surrender of the Leased Premises shall be valid unless it is in writing
and signed by a duly authorized officer or agent of Lessor.


 


SEC. 20RULES AND REGULATIONS:
Lessee shall comply with, and Lessee shall cause its visitors, employees, contractors, agents, invitees and licensees to comply
with, all laws, ordinances, orders, rules and regulations (state, federal, municipal and other agencies or bodies having any jurisdiction
thereof) relating to the use, condition or occupancy of the Leased Premises. Such reasonable rules and regulations applying to
all tenants in the Building as may be hereafter adopted by Lessor for the safety, care and cleanliness of the premises and the
preservation of good order thereon, are hereby made a part hereof and Lessee agrees to comply with all such rules and regulations.
Lessor shall have the right at all times to change such rules and regulations or to amend them in any reasonable manner as may
be deemed advisable by Lessor, all of which changes and amendments will be sent by Lessor to Lessee in writing and shall be thereafter
carried out and observed by Lessee. The current rules and regulations of the Building are set forth in Exhibit “C”
attached hereto and made a part hereof for all purposes


 


SEC. 21ASSIGNMENT BY LESSOR: Lessor
shall have the right to transfer and assign, in whole or in part, all its rights and obligations hereunder and in the Complex,
and in such event and upon such transfer no further liability or obligation shall thereafter accrue against Lessor hereunder. Furthermore,
Lessee specifically agrees to look solely to Lessor’s interest in the Complex for the recovery of any judgment from Lessor,
it being agreed that the Lessor Parties shall never be personally liable for any such judgment.


 


SEC. 22SEVERABILITY: This Lease
Agreement shall be construed in accordance with the laws of the State of Texas. If any clause or provision of this Lease Agreement
is illegal, invalid or unenforceable, under present or future laws effective during the Term hereof, then it is the intention of
the parties hereto that the remainder of this Lease Agreement shall not be affected thereby, and it is also the intention of both
parties that in lieu of each clause or provision that is illegal, invalid or unenforceable, there be added as part of this Lease
Agreement a clause or provision as similar in terms to such illegal, invalid or unenforceable clause or provision as may be possible
and be legal, valid and enforceable.


 


SEC. 23SIGNS: No signs of any
kind or nature, symbol or identifying mark shall be put on the Building, in the halls, elevators, staircases, entrances, parking
areas or upon the doors or walls, whether plate glass or otherwise, of the Leased Premises or within the Leased Premises so as
to be visible from the public areas or exterior of the Building without prior written approval of Lessor. All signs or lettering
shall conform in all respects to the sign and/or lettering criteria established by Lessor.


 






    	 



    	 



    

 


SEC. 24SUCCESSORS AND ASSIGNS: Lessor
and Lessee agree that all provisions hereof are to be construed as covenants and agreements as though the words imparting such
covenants were used in each separate paragraph hereof, and that, except as restricted by the provisions of the section entitled
“Subletting and Assigning” hereof, this Lease Agreement and all the covenants herein contained shall be binding upon
the parties hereto, their respective heirs, legal representatives, successors and assigns.


 


SEC. 25SUBORDINATION: 


 


A.Lessee covenants
and agrees with Lessor that this Lease Agreement is subject and subordinate to that certain Deed of Trust, Assignment of Leases
and Rents and Security Agreement dated effective as of December 20, 2012 executed for the benefit of Citigroup Global Markets Realty
Corp and its successors, which deed of trust was filed for record and recorded in the Real Property Records of Harris County, Texas
(the “Existing Mortgage”) and any other mortgage, deed of trust, ground lease and/or security agreement which may now
or hereafter encumber the Building or any interest of Lessor or its affiliates therein and/or the contents of the Building, and
to any advances made on the security thereof and to any and all increases, renewals, modifications, consolidations, replacements
and extension thereof (the Existing Mortgage and such other mortgages, deed of trust, ground leases and security agreements are
collectively referred to herein as the “Mortgages”). In the event of the enforcement by any owner, beneficiary or holder
of any such Mortgages of the remedies provided for by law or by such Mortgages, Lessee does hereby attorn to such owner, beneficiary
or holder, as its lessor, said attornment to be effective without the execution of any further instruments on the part of any of
the parties hereto, immediately upon Lessee receiving notice from such owner, beneficiary or holder that such party has succeeded
to the interest of Lessor under this Lease Agreement. This provision shall be self-operative and no further instrument of subordination
or attornment need be required by any owner, beneficiary or holder of any such Mortgages. Upon request by any owner, beneficiary
or holder of any such Mortgages, whether before or after the enforcement of its remedies, Lessee shall execute and deliver an instrument
or instruments confirming and evidencing the attornment herein set forth; provided, however, that any ground lessor, the trustee,
the beneficiary or the secured party under any Mortgages shall agree that Lessee’s peaceable possession of the Leased Premises
will not be disturbed on account thereof as long as Lessee is not in default of any of the terms and covenants of this Lease Agreement.
Lessee, upon request of any person or party succeeding to the interest of Lessor as a result of such enforcement, will automatically
become the Lessee of such ground lessor or successor in interest without any change in the terms or other provisions of this Lease
Agreement; provided, however, that such ground lessor or successor in interest shall not be (a) liable for any act or omission
of any prior landlord, (b) for any liability or obligation of any prior landlord occurring prior to the date such ground lessor
or successor in interest acquires title to the Building, (c) bound by any payment of Base Rent more than one (1) month in advance
except prepayments in the nature of security for the performance by Lessee of its obligations under this Lease Agreement, or (d)
bound by any amendment or modification of this Lease Agreement made without the written consent of such ground lessor or such successor
in interest. Notwithstanding anything contained in this Lease Agreement to the contrary, in the event of any default by Lessor
in performing its covenants or obligations hereunder, Lessee shall give written notice of such default (which notice shall specify
the exact nature of said default and how the same may be cured) to the holder of the Existing Mortgage and the owner or holder
of any other Mortgages who has theretofore notified Lessee in writing of its interest and the address to which notices are to be
sent, and thereupon the holder of the Existing Mortgage and the owner or holder of any such other Mortgages shall have the right
(but not the obligation) to cure such default. Lessee shall not exercise any rights afforded by this Lease Agreement (if any) including,
without limitation, terminating this Lease Agreement and abating the rent payable thereunder by reason of such default unless and
until Lessee has afforded the holder of the Existing Mortgage and the owner or holder of any such other Mortgages thirty (30) days
after the expiration of such time as Lessor was permitted to cure such default and a reasonable period of time in addition thereto
(i) if the circumstances are such that said default cannot reasonably be cured within said thirty (30) day period and the holder
of the Existing Mortgage and/or the owner or holder of any such other Mortgages has commenced and is diligently pursuing such cure,
or (ii) during and after any litigation action including a foreclosure, bankruptcy, possessory action or a combination thereof.
All notices to the holder of the Existing Mortgage shall be forwarded to Citigroup Global Markets Realty Corp, 388 Greenwich Street,
19th Floor, New York, New York 10013 Attn: Ana Rosu Marmann or such other address as may be specified by the holder
of the Existing Mortgage. This Lease Agreement is further subject to and subordinate to all matters of record in Harris County,
Texas.


 


B.Notwithstanding
anything to the contrary set forth above, any beneficiary under any deed of trust may at any time subordinate its deed of trust
to this Lease Agreement in whole or in part, without any need to obtain Lessee’s consent, by execution of a written document
subordinating such deed of trust to the Lease Agreement to the extent set forth in such document and thereupon the Lease Agreement
shall be deemed prior to such deed of trust to the extent set forth in such document without regard to their respective dates of
execution, delivery and/or recording. In that event, to the extent set forth in such document, such deed of trust shall have the
same rights with respect to this Lease Agreement as would have existed if this Lease Agreement had been executed, and a memorandum
thereof, recorded prior to the execution, delivery and recording of the deed of trust.


 


SEC. 26ACCESS BY LESSOR: INTENTIONALLY
DELETED.


 


SEC. 27TAX PROTEST: Lessee waives
all rights under the Texas Property Tax Code, now or hereafter in effect, including all rights under Section 41.413 thereof, granting
to tenants of real property or lessees of tangible personal property the right to protest the appraised value, or receive notice
of reappraisal, of all or any part of the Complex, irrespective of whether Lessor has elected to protest such appraised value.
To the extent such waiver is prohibited, Lessee appoints Lessor as its attorney-in-fact, coupled with an interest, to appear and
take all actions on behalf of Lessee which Lessee may take under the Texas Property Tax Code.


 






    	 



    	 



    

 


SEC. 28HOLDING OVER: In the
event of holding over by Lessee after the expiration or termination of the Lease Agreement, such hold over shall be as a tenant
at will and all of the terms and provisions of this Lease Agreement shall be applicable during such period, except that Lessee
shall pay Lessor as rental for the period of such hold over an amount equal to one hundred and fifty (150%) percent the rent payable
by Lessee for the month immediately preceding the holdover period, and Lessee will vacate the Leased Premises and deliver the same
to Lessor upon Lessee's receipt of notice from Lessor to vacate the Leased Premises. The rental payable during such hold over period
shall be payable to Lessor on demand. No holding over by Lessee, whether with or without consent of Lessor, shall operate to extend
this Lease Agreement except as herein provided. In the event of any unauthorized holding over, Lessee shall also indemnify, defend
(with counsel reasonably acceptable to Lessor) and hold harmless the Lessor Parties against all claims for damages against the
Lessor Parties as a result of Lessee’s possession of the Leased Premises, including, without limitation, claims for damages
by any other tenant to which Lessor may have leased all or any part of the Leased Premises effective upon the termination of this
Lease Agreement. Notwithstanding anything contained herein to the contrary, under no circumstances shall Lessee be liable for any
consequential, special or incidental damages incurred by Lessor as a result of any holding over in the Leased Premises by Lessee
for the first month of any such holdover period.


 


SEC. 29INDEPENDENT OBLIGATION TO
PAY RENT: It is the intention of the parties hereto that the obligations of Lessor and Lessee hereunder shall be separate and
independent covenants and agreements, that the rent and all other sums payable by Lessee hereunder shall continue to be payable
in all events and that the obligations of Lessee hereunder shall continue unaffected, unless the requirement to pay or perform
the same shall have been terminated pursuant to an express provision of this Lease Agreement.


 


Lessee agrees that
it will remain obligated under this Lease Agreement in accordance with its terms, and that it will not take any action to terminate,
rescind or void this Lease Agreement, notwithstanding (a) the bankruptcy, insolvency, reorganization, composition, readjustment,
liquidation, dissolution, winding up or other proceeding affecting Lessor or any assignee of Lessor in any such proceeding and
(b) any action with respect to this Lease Agreement which may be taken by any trustee or receiver of Lessor or of any assignee
of Lessor in any such proceeding or by any court in any such proceeding.


 


Except as otherwise
expressly provided herein, Lessee waives the right (a) to quit, terminate or surrender this Lease Agreement or the Leased Premises
or any part thereof, or (b) to any abatement, suspension, deferment or reduction of the rent or any other sums payable under this
Lease Agreement.


 


SEC. 30INDEMNITY; RELEASE AND WAIVER;
INSURANCE:


 


A.Lessee hereby
agrees to indemnify, protect, defend and hold the Lessor Parties harmless from and against any and all liabilities, claims, causes
of action, fines, damages, suits and expenses, including reasonable attorneys’ fees and necessary litigation expenses (collectively,
the “Claims”), arising from Lessee’s use, occupancy or enjoyment of the Leased Premises and its facilities for
the conduct of its business or from any activity, work or thing done, permitted, omitted or suffered by Lessee and its partners,
officers, directors, employees, agents, servants, contractors, customers, licensees and invitees in or about the Leased Premises,
 INCLUDING ANY CLAIMS RESULTING FROM THE ORDINARY NEGLIGENCE OF THE LESSOR PARTIES, BUT NOT THE SOLE GROSS NEGLIGENCE OR WILLFUL
MISCONDUCT OF THE LESSOR PARTIES and Lessee further agrees to indemnify, protect, defend and hold the Lessor Parties harmless
from and against any and all Claims arising from any breach or default in the performance of any obligation on Lessee’s part
to be performed under the terms of this Lease Agreement or arising from any gross negligence or willful misconduct of Lessee or
any of its partners, officers, directors, employees, agents, servants, contractors, customers, licensees and invitees, EXCLUDING
ANY CLAIMS RESULTING FROM THE NEGLIGENCE, GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF THE LESSOR PARTIES. In case any action
or proceeding shall be brought against the Lessor Parties by reason of any such Claim, Lessee, upon notice from Lessor, shall provide
a separate defense to same at Lessee’s sole cost and expense by counsel reasonably satisfactory to Lessor. The indemnity
obligations of Lessee under this Section 30 shall survive the expiration or earlier termination of this Lease Agreement.


 


B.Lessor shall
defend, indemnify, and hold harmless Tenant and its agents from and against all Claims, for any loss arising from any occurrence
in or on the Common Areas; however, such indemnity shall not apply to the gross negligence or willful misconduct of Tenant or its
invitees, servants, contractors, customers, licensees and agents.


 


C.Lessee hereby
releases the Lessor Parties from any and all claims or causes of action whatsoever which Lessee might otherwise now or hereafter
possess resulting in or from or in any way associated with any loss covered or which should have been covered by insurance in accordance
with the requirements of this Lease Agreement, REGARDLESS OF CAUSE OR ORIGIN OF SUCH LOSS OR DAMAGE, INCLUDING, WITHOUT LIMITATION,
SOLE, JOINT, OR CONCURRENT NEGLIGENCE OF THE LESSOR PARTIES, including the deductible and/or uninsured portion thereof, maintained
and/or required to be maintained by Lessee pursuant to this Lease Agreement.


 


D.Lessor and Lessee
shall satisfy the insurance requirements as more particularly described on Exhibit “G” attached hereto and made a part
hereof for all purposes. In no event shall Lessee’s liability under this Lease Agreement be limited by the amount of insurance
required to be carried under Exhibit “G”.


 


SEC. 31ENTIRE AGREEMENT: This
instrument and any attached addenda or exhibits signed by the parties constitute the entire agreement between Lessor and Lessee;
no prior written or prior or contemporaneous oral promises or representations shall be binding. This Lease Agreement shall not
be amended, changed or extended except by written instrument signed by both parties hereto. Paragraph captions herein are for Lessor's
and Lessee's convenience only, and neither limit nor amplify the provisions of this instrument. Lessee agrees, at Lessor's request,

SEC. 33COMMENCEMENT DATE: Lessee
shall, if requested by Lessor, execute and deliver to Lessor an Acceptance of Premises Memorandum of the Leased Premises, the form

SEC. 34RELOCATION OF LESSEE: Lessor
shall have the option to relocate the Lessee (the "Relocation Option") to alternate space within the Building (the "Alternate
Space"), which Alternate Space shall be (i) exterior facing (i.e. not facing the atrium within the Building), and (ii)
of comparable size to or larger than the Leased Premises, in accordance with this Section 34. Lessor shall give Lessee not less
than ninety (90) days prior written notice (the "Relocation Notice") of Lessor's exercise of the Relocation Option, which
Relocation Notice shall include the date on which the Lessee shall be required to relocate or move and a description of the Alternate
Space. Lessor shall pay all reasonable out-of-pocket costs and expenses of relocating Lessee (including the cost of preparing the
Alternate Space for occupancy), provided (i) such costs are approved by Lessor in advance, which approval shall not be unreasonably
withheld, conditioned or delayed and (ii) Lessee provides Lessor with documentation reasonably acceptable to Lessor confirming
that Lessee in fact incurred such costs. In the event of such relocation, the Alternate Space shall for all purposes be deemed
the Leased Premises hereunder and this Lease Agreement shall continue in full force and effect without any change in the other
terms or conditions hereof (including Lessee’s pro rata share, as set forth in Section 6.C, and the amounts payable by Lessee
for Base Rent). Lessee agrees to cooperate with Lessor and/or its contractors, agents and employees in connection with such relocation
so that the Alternate Space will be ready for occupancy on the anticipated relocation commencement date. Notwithstanding anything
contained herein to the contrary, Lessor agrees that it shall not exercise the Relocation Option more than one (1) time during
the primary Term of this Lease Agreement.


 


SEC. 35BROKERS: Lessee warrants
that it has had no dealings with any real estate broker or agent in connection with the negotiation of this Lease Agreement, excepting
only the broker(s) named Transwestern for Lessor and Coldwell Banker Commercial United for Lessee and that it knows of no other
real estate broker(s) or agent(s) who is(are) or might be entitled to a commission in connection with this Lease Agreement. Lessor
shall agree to pay all real estate commissions due in connection with this Lease Agreement only to the broker(s) named herein,
provided Lessor and such broker have entered into a separate commission agreement. Lessee agrees to indemnify, defend (with counsel
reasonably acceptable to Lessor) and hold harmless the Lessor Parties from and against any liability from all other claims for
commissions arising from the negotiation of this Lease Agreement.


 


SEC. 36ESTOPPEL CERTIFICATES:
From time to time after Lessee accepts the Leased Premises, within ten (10) days after request in writing therefor from Lessor,
Lessee agrees to execute and deliver to Lessor, or to such other addressee or addresses as Lessor may designate (and Lessor and
any such addressee may rely thereon), a statement in writing in the form of Exhibit “E” or in such other form and substance
satisfactory to Lessor (herein called “Lessee's Estoppel Certificate”), certifying to all or any part of the information
provided for in Exhibit “E” as is requested by Lessor.


 


SEC. 37NAME CHANGE: Lessor and
Lessee mutually covenant and agree that Lessor hereby reserves and shall have the right at any time and from time to time to change

SEC. 38BANKRUPTCY: If a petition
is filed by or against Lessee for relief under Title 11 of the United States Code, as amended (the “Bankruptcy Code”),
and Lessee (including for purposes of this Section Lessee’s successor in bankruptcy, whether a trustee or Lessee as debtor
in possession) assumes and proposes to assign, or proposes to assume and assign, this Lease Agreement pursuant to the provisions
of the Bankruptcy Code to any person or entity who has made or accepted a bona fide offer to accept an assignment of this Lease
Agreement on terms acceptable to Lessee, then notice of the proposed assignment setting forth (a) the name and address of the proposed
assignee, (b) all of the terms and conditions of the offer and proposed assignment, and (c) the adequate assurance to be furnished
by the proposed assignee of its future performance under the Lease Agreement, shall be given to Lessor by Lessee no later than
twenty (20) days after Lessee has made or received such offer, but in no event later than ten (10) days prior to the date on which
Lessee applies to a court of competent jurisdiction for authority and approval to enter into the proposed assignment. Lessor shall
have the prior right and option, to be exercised by notice to Lessee given at any time prior to the date on which the court order
authorizing such assignment becomes final and non-appealable, to receive an assignment of this Lease Agreement upon the same terms
and conditions, and for the same consideration, if any, as the proposed assignee, less any brokerage commissions which may otherwise
be payable out of the consideration to be paid by the proposed assignee for the assignment of this Lease Agreement. If this Lease
Agreement is assigned pursuant to the provisions of the Bankruptcy Code, Lessor: (i) may require from the assignee a deposit or
other security for the performance of its obligations under the Lease Agreement in an amount substantially the same as would have
been required by Lessor upon the initial leasing to a Lessee similar to the assignee; and (ii) shall receive, as additional rent,
the sums and economic consideration described in Section 12.A(3)(e). Any person or entity to which this Lease Agreement is assigned
pursuant to the provisions of the Bankruptcy Code shall be deemed, without further act or documentation, to have assumed all of
the Lessee’s obligations arising under this Lease Agreement on and after the date of such assignment. Any such assignee shall,
upon demand, execute and deliver to Lessor an instrument confirming such assumption. No provision of this Lease Agreement shall
be deemed a waiver of Lessor’s rights or remedies under the Bankruptcy Code to oppose any assumption and/or assignment of
this Lease Agreement, to require a timely performance of Lessee’s obligations under this Lease Agreement, or to regain possession
of the Leased Premises if this Lease Agreement has neither been assumed on or rejected within sixty (60) days after the date of
the order for relief or within such additional time as a court of competent jurisdiction may have fixed. Notwithstanding anything
in this Lease Agreement to the contrary, all amounts payable by Lessee to or on behalf of Lessor under this Lease Agreement, whether
or not expressly denominated as rent, shall constitute rent for the purposes of Section 502(b)(6) of the Bankruptcy Code.


 


SEC. 39TELECOMMUNICATIONS PROVIDERS:
In the event Lessee wishes to use, at any time during the Term of this Lease Agreement, the services of a telecommunications provider
whose equipment or service is not then in the Building, no such provider shall be entitled to enter the Building or commence providing
such service without first obtaining the prior written consent of Lessor, which consent shall not be unreasonably withheld, conditioned
or delayed. Lessor may condition its consent on such matters as Lessor deems reasonably appropriate including, without limitation,
(i) such provider agreeing to an easement or license agreement in form and substance satisfactory to Lessor, (ii) Lessor having
been provided and approved the plans and specifications for the equipment to be installed in the Building, (iii) Lessor has received,
prior to the commencement of such work, such indemnities, bonds or other financial assurances as Lessor may require, (iv) the provider
agreeing to abide by all Building rules and regulations, and agreeing to provide Lessor an “as built” set of plans
and specifications, (v) the provider agreeing to pay Lessor such compensation as Lessor determines to be reasonable, and (vi) Lessor
having determined that there is adequate space in the Building for the placement of all of such provider’s lines and equipment.


 


SEC. 40HAZARDOUS SUBSTANCES:


 


A.Lessee shall
not cause or permit any Hazardous Substance (as hereinafter defined) to be used, stored, generated or disposed of on or in the
Complex by Lessee, Lessee’s agents, employees, contractors or invitees. If Hazardous Substances are used, stored, generated
or disposed of on or in the Complex, or if the Complex becomes contaminated in any manner due to the actions or omissions of Lessee
or its agents, employees, contractors or invitees, Lessee shall indemnify, defend (with counsel reasonably acceptable to Lessor)
and hold the Lessor Parties harmless from any and all claims, damages, fines, judgments, penalties, costs, liabilities and losses
(including, without limitation, a decrease in value of the Complex, damages caused by loss or restriction of rentable or usable
space or any damages caused by adverse impact on marketing of the space and any and all sums paid for settlement of claims, attorneys’
fees, consultant and expert fees) arising during or after the Term and as a result of such use, storage, generation, disposal or
contamination. This indemnification includes, without limitation, any and all costs incurred because of any investigation of the
site or any cleanup, removal or restoration mandated by a federal, state or local agency or political subdivision. Without limitation
of the foregoing, if Lessee causes or permits the presence of any Hazardous Substance on the Complex that results in contamination,
Lessee shall promptly, at its sole expense, take any and all necessary actions to return the Complex to the condition existing
prior to the presence of any such Hazardous Substance on the Complex; provided, however, Lessee must obtain Lessor’s prior
written approval, not to be unreasonably withheld, conditioned or delayed, for any such remedial action. The indemnity obligations
of Lessee under this Section 39 shall survive the expiration or earlier termination of this Lease Agreement.


 


B.As used herein,
“Hazardous Substance” means any substance (i) that is toxic, ignitable, reactive or corrosive or that is regulated
by any local, state or federal law, and includes any and all material or substances that are defined as “hazardous waste”,
“extremely hazardous waste”, “hazardous substance” or a “hazardous material” pursuant to any
such laws and includes, but is not limited to, asbestos, polychlorobiphenyls and petroleum and any fractions thereof and (ii) which
is now or hereafter considered a biological contaminant or which could adversely impact air quality, including mold, fungi and
other bacterial agents. Notwithstanding anything in this Section 39 to the contrary, “Hazardous Substances” shall not
include materials commonly used in the ordinary operations of a general office building, provided that (1) such materials are used

SEC. 41NO MONEY DAMAGES FOR FAILURE
TO CONSENT: Wherever in this Lease Agreement Lessor’s consent or approval is required, if Lessor refuses to grant such
consent or approval, whether or not Lessor expressly agreed that such consent or approval would not be unreasonably withheld, Lessee
shall not make, and Lessee hereby waives, any claim for money damages (including any claim by way of set-off, counterclaim or defense)
based upon Lessee’s claim or assertion that Lessor unreasonably withheld or delayed its consent or approval. Lessee’s
sole remedy shall be an action or proceeding to enforce such provision, by specific performance, injunction or declaratory judgment.
EXCEPT AS PROVIDED IN SECTION 28 OF THIS LEASE AGREEMENT, IN NO EVENT SHALL THE LESSOR OR LESSEE PARTIES BE LIABLE FOR, AND
LESSEE AND LESSOR HEREBY WAIVE ANY CLAIM FOR, ANY INDIRECT, CONSEQUENTIAL OR PUNITIVE DAMAGES, INCLUDING LOSS OF PROFITS OR BUSINESS
OPPORTUNITY, ARISING UNDER OR IN CONNECTION WITH THIS LEASE AGREEMENT.


 


SEC. 42ACKNOWLEDGMENT OF NON-APPLICABILITY
OF DTPA: It is the understanding and intention of the parties that Lessee’s rights and remedies with respect to the transactions
provided for and contemplated in this Lease Agreement (collectively, this “Transaction”) and with respect to all acts
or practices of Lessor, past, present or future, in connection with this Transaction, are and shall be governed by legal principles
other than the Texas Deceptive Trade Practices - Consumer Protection Act (the “DTPA”). Accordingly, Lessee hereby (a)
agrees that under Section 17.49(f) of the DTPA this Transaction is not governed by the DTPA and (b) certifies, represents and warrants
to Lessor that (i) Lessee has been represented by legal counsel in connection with this Transaction who has not been directly or
indirectly identified, suggested or selected by the Lessor and Lessee has conferred with Lessee’s counsel concerning all
elements of this Lease Agreement (including, without limitation, this Section 41) and this Transaction and (ii) the Leased Premises
will not be occupied by Lessee as Lessee’s family residence. Lessee expressly recognizes that the total consideration as
agreed to by Lessor has been predicated upon the inapplicability of the DTPA to this Transaction and that Lessor, in determining
to proceed with the entering into of this Lease Agreement, has expressly relied on the inapplicability of the DTPA to this Transaction.


 


SEC. 43ATTORNEYS’ FEES:
In the event either party defaults in the performance of any of the terms, agreements or conditions contained in this Lease Agreement
and the other party places the enforcement of this Lease Agreement, or any part thereof, or the collection of any rent due or to
become due hereunder, or recovery of the possession of the Leased Premises, in the hands of an attorney who files suit upon the
same, and should such non-defaulting party prevail in such suit, the defaulting party agrees to pay the other party’s reasonable
attorneys’ fees.


 


SEC. 44AUTHORITY OF LESSEE:
If Lessee is a corporation, partnership or other entity, Lessee warrants and represents unto Lessor that (a) Lessee is a duly organized
and existing legal entity, in good standing in the State of Texas, (b) Lessee has full right and authority to execute, deliver
and perform this Lease Agreement, (c) the person executing this Lease Agreement was authorized to do so and (d) upon request of
Lessor, such person will deliver to Lessor satisfactory evidence of his or her authority to execute this Lease Agreement on behalf
of Lessee.


 


SEC. 45INABILITY TO PERFORM: Whenever
a period of time is prescribed for the taking of an action by Lessor, the period of time for the performance of such action shall
be extended by the number of days that the performance is actually delayed due to strikes, acts of God, shortages of labor or materials,
war, terrorist attacks (including bio-chemical attacks), civil disturbances and other causes be yond the reasonable control of
the Lessor (“Force Majeure” ).


 


SEC. 46JOINT AND SEVERAL TENANCY:
If more than one person executes this Lease Agreement as Lessee, their obligations hereunder are joint and several, and any act
or notice of or to, or refund to, or the signature of, any one or more of them, in relation to the renewal or termination of this
Lease Agreement, or under or with respect to any of the terms hereof shall be fully binding on each and all of the persons executing
this Lease Agreement as a Lessee.


 


SEC. 47EXECUTION OF THIS LEASE AGREEMENT:
The submission of an unsigned copy of this Lease Agreement to Lessee for Lessee’s consideration does not constitute an offer
to lease the Leased Premises or an option to or for the Leased Premises. This Lease Agreement shall become effective and binding
only upon the execution and delivery of this Lease Agreement by both Lessor and Lessee.


 


SEC. 48WAIVER OF TRIAL BY JURY;
COUNTERCLAIM: Lessor and Lessee hereby waive trial by jury in any action, proceeding or counterclaim brought by either party
against the other on any matters in any way arising out of or connected with this Lease Agreement, the relationship of Lessor and
Lessee, Lessee’s use or occupancy of the Leased Premises, or the enforcement of any remedy under any applicable law, rule,
statute, order, code or ordinance. If Lessor commences any summary proceeding against Lessee, Lessee shall not interpose any counterclaim
of any nature or description in any such proceeding (unless failure to impose such counterclaim would preclude Lessee from asserting
in a separate action the claim which is the subject of the counterclaim), and will not seek to consolidate any such proceeding
with any other action which may have been or will be brought in any other court by Lessee.


 


SEC. 49CALCULATION OF TIME PERIODS:
Should the calculation of any of the various time periods provided for herein result in an obligation becoming due on a Saturday,
Sunday or legal holiday, then the due date of such obligation or scheduled time of occurrence of such event shall be delayed until
the next business day.

SEC. 51 CHARGES IN LEASE: Lessor
and Lessee agree that each provision of the Lease Agreement for determining charges, amounts, and expenses payable by Lessee is
commercially reasonable and, as to each such charge or amount, constitutes a “method by which the charge is to be computed”
for purposes of Section 93.012 of the Texas Property Code.


 


SEC. 52 COUNTERPARTS: This Lease
Agreement may be executed in multiple counterparts, each of which is an original and all of which together constitutes one and
the same document.


 


SEC. 53 EXTENSION OPTION: Provided
no event of default has occurred and is continuing under this Lease Agreement, Lessee is hereby granted the option to extend the
Lease Agreement Term for one (1) additional period of sixty (60) months ("Extension Term") commencing upon the expiration
of the initial Lease Agreement Term on the same terms and conditions as contained in the other provisions of this Lease Agreement.
This option shall be exercised only by delivery of written notice (the "Renewal Notice") to Lessor no later than six
(6) months prior to the then-scheduled expiration date of this Lease Agreement. The Minimum Annual Rent for the Leased Premises
during Extension Term shall be at the Market Rate (as hereinafter defined).


 


The term "Market
Rate," as used in this Lease Agreement, shall mean the fair market value rental rate for space in comparable buildings in
the Bellaire, Texas submarket taking into consideration the location, quality and age of the building, floor level, extent of leasehold
improvements, if any, to be provided by Lessor, rent abatements, concessions, term, extent of services to be provided, distinction
between "gross" and "net" Lease Agreement, expense stop, if any, base year, if any, or any other pertinent
factor, at the time the particular rental rate under consideration became or is to become effective. Within thirty (30) days after
receipt of Lessee's notice to renew, Lessor and Lessee shall use reasonable efforts to agree upon the Market Rate. If Lessee and
Lessor shall fail to agree upon the Market Rate within such thirty (30) day period, then this renewal option shall expire and be
considered null and void.
