2.Lease Grant.Landlord, in
consideration of: (i) the Basic Rental, (ii) all other sums to be paid by Tenant under this Lease ("Additional Rental") and (iii) the other covenants and agreements to be
performed by Tenant; hereby leases, demises and lets to Tenant the Premises (as defined in paragraph 1(c)) on the terms and conditions stated in this Lease commencing on the commencement date
(as defined in paragraph 1(d), or as adjusted as provided below) and ending on the expiration date, unless sooner terminated as provided in this Lease. If this Lease is executed before the
Premises become vacant, or otherwise available and ready for occupancy, or if any present tenant or occupant of the Premises holds over, and Landlord cannot acquire possession of the Premises prior to
the commencement date of this Lease, Landlord shall not be deemed to be in default hereunder, and Tenant agrees to accept possession of the Premises at such time as Landlord is able to tender the same
and such date shall be deemed to be the commencement date and this Lease shall continue for the lease term described in paragraph 1(d) above. Landlord waives payment of rent covering any period
prior to the rendering of possession of the Premises to Tenant. If Tenant occupies the Premises prior to the commencement date specified in paragraph 1(d), the commencement date shall be
altered to coincide with said occupancy and the ending date of the Lease remaining unchanged. Tenant is responsible for obtaining, at its expense, a certificate of occupancy for the Premises. Tenant
shall promptly apply for the certificate of occupancy and diligently pursue all necessary approvals required to occupy and use the Premises for the purpose set out in this Lease. By occupying the
Premises, Tenant shall be deemed to have acknowledged that the Premises (i) are suitable for Tenant's intended purpose (ii) are in good operating condition and (iii) comply fully
with Landlord's obligations under this Lease.

3.Rent.Tenant shall pay Basic Rental to Landlord without
demand, deduction or set off, for each month of the entire Lease term. Until further notice, payments are due at the address set out in this Lease document. Tenant shall, contemporaneously with the
execution of this Lease, pay Landlord the following: (i) the security deposit set out in paragraph 1(f) above and (ii) an initial
one-and-one-half months installment of rent (as defined in paragraph 1(e)). A monthly installment in the amounts defined in paragraphs 1(e) above shall be
due and payable on or before the first day of each succeeding calendar month during the Lease term. Rent for any fractional month at the beginning or end of the Lease term shall be prorated. The
security deposit shall be held by Landlord without liability for interest and as security for the performance by Tenant of Tenant's covenants and obligations under this Lease, it being expressly
understood that the deposit shall not be considered an advance payment of any rental or a measure of Landlord's damages in case of default by Tenant. If Tenant fails to timely pay any sums due under
this Lease or defaults in its obligations under this Lease, Landlord may, from time to time, without prejudice to any other remedy, use the security deposit to the extent necessary to make good any
arrearages of Basic Rental or any damage, injury, expenses or liability to Landlord. Following any such application of the security deposit, Tenant shall immediately pay to Landlord, on demand, the
amount so applied in order to

Page 2

restore
the security deposit to its original amount. 30 days after termination of this Lease and vacating of the Premises by Tenant, Landlord shall return any remaining balance of the security
deposit to Tenant so long as Tenant has full performed its obligations under this Lease and provided Landlord with written notice of its forwarding address. If Landlord transfers its interest in the
Premises during the Lease term, Landlord may assign the security deposit to the transferee and thereafter shall have no further liability for the return of such security deposit.

Time
is of the essence as to all required payments by Tenant under any provision of this Lease. If any monthly installment of Basic Rental is not received by the Landlord on or before
the 5th day of the month for which said monthly rental installment is due, a service charge of 10% of the delinquent installment shall become due and payable in addition to the monthly installment
owed. The date that a check is dated or mailed is not relevant in determining Tenant's liability for a late fee; Landlords accounting records are the determining record of the date of receipt of a
rent payment. The service charge is for the purpose of reimbursing Landlord for the extra costs and expenses incurred in connection with the handling and processing of late monthly rental. If the
delinquent amount is not paid by the 1st day of the following month, then the delinquent amount (not including the service charge) shall bear interest at the lesser of: (1) 18 per cent per
annum, or (2) the maximum lawful contract rate. Such interest shall begin to accrue on the 1st of the month following the delinquency and continue until payment of the delinquent amount is
made.

If
any check that is tendered to Landlord by Tenant for any charges due under this Lease is returned to Landlord by Tenants financial institution for any reason (including but not
limited to absence of Tenants signature, insufficient funds, stop payment, or closed account) then, in addition to any other liability of Tenant for the amount of the check, Tenant shall be liable to
Landlord for a service fee of $50.00 for each returned check. Landlord has no obligation to redeposit any check that is returned for any reason and Tenant shall immediately cure the
non-payment that has resulted from the returned check. If Landlord receives 2 or more returned checks during the term of this Lease, then Landlord may require that all future payments from
Tenant be made by cashiers check.

responsible for paying the cost of all utilities.

(b)Intentionally Deleted.

(c)Landlord shall have no liability for any impairment of any utility or other services to the Premises resulting from any
stoppage, interruption or inadequacy. If there is any such impairment of utility or other services, Landlord shall not be liable for any resulting damages to either person, property or business
operations and the impairment shall not: (i) constitute an eviction of Tenant, or (ii) entitle Tenant to any abatement or reduction of Tenant's obligations under this Lease.

6.Leasehold Improvements.Leasehold improvements shall be made
at the direction of the Tenant, subject to approval of Landlord not to be unreasonably withheld. The first Six Hundred Thousand Dollars ($600,000.00) of such improvements shall be paid by Landlord,
and Basic Rental, per paragraph 1(e) shall not be altered in any manner as a result of such improvements. Any improvements exceeding this Six Hundred Thousand Dollar ($600,000.00) cap shall be
the sole responsibility of the Tenant. In the event that Tenant exercises the Purchase Option in paragraph 1(h), the amount that improvements paid for by Landlord exceeds Two Hundred Thousand
Dollars ($200,000.00) shall be added to the option price in paragraph 1(h).

7.Use.Tenant shall use the Premises only for the permitted use
(as defined in paragraph 1(g)). Tenant will not occupy or use the Premises, or permit any portion of the Premises to be occupied or used for any business or purpose other than the permitted use

Exhibit "B") or contents. If Tenants occupancy causes any increase in the rate of insurance on the Premises Tenant agrees to pay to Landlord the amount of such increase on demand and such
increase shall be Additional Rental. Tenant will conduct its business and control its vendors; subcontractors; agents; employees and invitees in such a manner as not to create any nuisance, nor
interfere with, annoy or disturb other tenants (if any), the Landlord or any property owners adjacent to the Project (as defined in Exhibit "B"). Tenant will maintain the Premises in a clean,

the items that Landlord is obligated to repair under this Lease; Landlord shall promptly perform any such repairs that Landlord in its reasonable judgment determines are necessary. Tenant shall have

agreements may, at lenders election, include a provision providing for continuation of this Lease following the lenders exercise of any remedy against Landlord and further providing that lenders
liability under this Lease will be limited to times following its taking title or possession of the Premises. Subordination Agreements shall be signed by Tenant and returned to Landlord or any lender

option, may waive the applicability of this paragraph 13 so that this Lease will not be subject and subordinate to any such deed of trust, security interest or mortgage.

14.Required Insurance.Landlord shall maintain insurance
policies that insure the improvements on the Project (including the Premises) against loss due to fire and such other hazards as Landlord may determine from time to time. Such insurance may be in
amounts and have deductibles that Landlord may from time to time elect. Landlord shall not be obligated to insure any personal property, fixtures, trade equipment, or inventory that may be placed from
time to time on the Premises. In addition, Landlord has no obligation to insure any improvements that Tenant may make to the Premises such as initial tenant space finishes (including carpet, drop
ceiling, interior partitions, etc.) or subsequent additions or improvements by Tenant (whether or not approved by Landlord).

Tenant
shall, at its sole cost and expense, procure and maintain throughout the term of this Lease a Commercial General Liability insuring both Tenant and Landlord against property
damage, bodily injury, personal injury or medical expenses occasioned by or arising out of or in connection with the use or occupancy of the Premises. The policy shall (i) be in an amount not

deem advisable, (iv) show the Premises to prospective insurers, tenants, purchasers or lenders. Such entry shall not entitle Tenant to any abatement or reduction of rent and shall not be deemed
to be an actual or constructive eviction. In addition, Landlord may enter the Premises at any time (by having the locks picked if necessary) if necessary in Landlords sole discretion in order to deal
with emergency situations or enforce its right of entry to regain possession due to any Tenant default. Landlords right of entry under this paragraph does not imply any duty on the part of Landlord to
take any actions whatsoever with regard to the Premises; such obligations, if any, are set out elsewhere in this Lease.

16.Condemnation.During the term of this Lease (including any
extension or renewal), if all or part of the Premises or the Project are taken for any public or quasi-public use under any governmental law, ordinance or regulation or by right of eminent domain
(including private purchase in lieu of condemnation) this Lease shall terminate and the rent shall be abated for the balance of the Lease term, effective on the date physical possession is taken by
the condemning authority. Tenant shall have no claim against Landlord for the value of any remaining term of this Lease.

If
a portion but not all of the Premises or Project shall be taken as described above and the partial taking or condemnation renders the Premises reasonably unsuitable for Tenant's
business, then Landlord may, in its sole discretion, elect to either (i) terminate this Lease or (ii) at Landlord's sole risk and expense, restore and reconstruct the Premises or Project
to the extent necessary to make same reasonably tenantable. If Landlord elects to restore the Premises or Project, this Lease shall continue in full force and effect with the rent payable during the
remaining portion of the term being adjusted to such an extent as may be fair and reasonable under the circumstances. Tenant shall have no claim against Landlord for the damage, injury or impaired
leasehold value that results from any interrupted portion of this Lease.

In
the event of any total or partial condemnation or taking Tenant shall not be entitled to any part of the award or price paid in lieu thereof, and Landlord shall receive the full
amount of such award or price. Tenant hereby expressly waives any right or claim to any part of the condemnation proceeds or payments made in connection with a sale in lieu of condemnation.

17.Fires or Other Casualty.Tenant shall promptly notify
Landlord of any damage to the Premises or the Project by reason of vandalism, break in, storm, fire or any other casualty. If the Premises or Project are (i) totally destroyed by fire, tornado,
wind storm or other casualty or (ii) so damaged that rebuilding or repairs cannot be completed within ninety (90) days after the date of such damage, either Landlord or Tenant may, at
its option, terminate this Lease. Such election must be made within 15 days after the scope of the casualty is determined and termination shall be effective as of the date of the casualty and
rent shall abate as of that date. If Landlord's insurance covers the damage, and either (i) rebuilding or repairs can be completed within ninety (90) days after the date of such damage,
or (ii) the repairs require longer than 90 days (but both Landlord nor Tenant have waived the right to terminate this Lease), then Landlord shall, within (30) days after the date
of such damage, commence to rebuild or repair the Premises or the Project. The restoration shall proceed with reasonable diligence to restore the Premises or Project to substantially the same
condition in which it was immediately prior to the casualty, but Landlord shall not be obligated to rebuild, repair or replace any part of the furniture, equipment, fixtures and other improvements
which may have been placed by Tenant or other tenants within the Project or the Premises. Landlord shall allow Tenant a prorated diminution of Basic Rental based on (i) the number of days and
(ii) percentage of the leased area are not that are not available for Tenants use.

If
any deed of trust, security agreement or mortgage on the Premises or the Project requires that the insurance proceeds be used to retire the mortgage debt, Landlord shall have no
obligation to rebuild and this Lease shall terminate upon notice to Tenant. Any insurance that may be carried by Landlord or Tenant against loss or damage to the Project or to the Premises shall be
for the sole benefit of the party carrying such insurance and under its sole control.

18.Holding Over.After the expiration of the term of this Lease
if Tenant, or any of its successors in interest, continues to occupy any portion of the Premises then a tenancy from month to month will be created. Monthly rent during the holdover period will be
150% of the monthly Basic Rental in effect prior to the end of the Lease term. Nothing in this paragraph or otherwise constitutes an agreement by Landlord to permit any holding over after the end of
the term.

19.Taxes on Tenant's Property.Tenant shall be liable for all
taxes levied or assessed against personal property, furniture, or fixtures placed by Tenant in the Premises. If any such taxes for which Tenant is liable are levied or assessed against Landlord or
Landlord's property and if Landlord elects to pay the same or if the assessed value of Landlord's property is increased by inclusion of personal property, furniture or fixtures placed by Tenant in the
Premises, and Landlord elects to pay the taxes based on such increase, Tenant shall pay to Landlord upon demand that part of such taxes for which Tenant is primarily liable.

20.Events of Default.The following events shall be deemed to
be events of default by Tenant under this Lease:

(a)Tenant fails to pay any required installment of Basic Rental or any other charges due under this Lease and such failure
shall continue for a period of ten (10) calendar days. Payments are effective only when the check is actually received by Landlord without regard to the date on the check or the date the check
was mailed.

(b)Tenant fails to comply with any term, provision or covenant of this Lease, other than the payments described in
subsection (a) above, and does not cure such failure within ten (10) calendar days after written notice of the noncompliance is sent to Tenant. Cure notices sent under this
paragraph 20 (b) are effective on the sooner of the following: (i) the date a notice sent by certified or registered mail is signed for or refused by the addressee or delivery of
such notice is not possible because the addressee has moved, (ii) the date that a notice is actually delivered to Tenant at the Premises or posted on the main entry to the Premises.

(c)Tenant suffers material financial deterioration as evidenced by any of the following:

---



(d)Tenant repudiates its obligations under this Lease or deserts, vacates or abandons any substantial portion of the
Premises for a period of five (5) or more days.

(e)Tenant or any of the principals of Tenant has provided Landlord or any of its agents with false or incomplete information
on any application to rent the Premises.

The
following will be deemed to be a default by Landlord and a breach of this Lease: Landlord fails to perform any of Landlords obligations under this Lease within forty-five
(45) days after receipt of written notice from Tenant specifying the failure. No such failure, however, will be deemed to exist if Landlord has commenced to cure the default within such period
and provided such efforts are prosecuted to completion with reasonable diligence. Delay in curing a default will be excused if due to causes beyond the reasonable control of Landlord. If Landlord
remains in default beyond any applicable cure period then Tenant may as its sole and exclusive remedy, terminate this Lease and vacate the Premises. Upon such termination, Tenants obligation for rent
(and other charges such as Additional Rental, increases in operating expenses and utility services) shall cease. Tenants remedies described in this paragraph are the sole remedies for any Landlord
default or breach of this Lease by Landlord. Tenant waives any other remedies for damages (whether special, general or consequential) or specific performance.

21.Remedies.Upon the occurrence of any event of default by
Tenant specified in paragraph 20, Landlord shall have the option to pursue any one or more of the following remedies without any notice or demand whatsoever:

(a)Terminate this Lease in which event Tenant shall immediately surrender the Premises to Landlord, and if Tenant fails to
do so, Landlord may, without prejudice to any other remedy which it may have for possession or arrearages in rent, enter upon and take possession and expel or remove Tenant and any other person who
may be occupying all or part of the Premises, by force if necessary, without being liable for prosecution or any claim of damages. Tenant agrees to pay to Landlord on demand the amount of all loss and
damage which Landlord may suffer by reason of such termination, whether through inability to rent the Premises on satisfactory terms or otherwise, including the loss of rental for the remainder of the
Lease term.

(b)Enter upon and take possession of the Premises and expel or remove Tenant and any other person occupying all or part of
the Premises, by force if necessary, without being liable for prosecution or any claim for damages, but without terminating this Lease. If Landlord reenters the Premises and takes possession by
changing the locks, Tenant remains liable for all required payments under this Lease. If Landlord takes possession of the Premises by locking Tenant out under the terms of this Lease, Landlord has no
obligation to make new keys available other than during the Landlord's normal business hours and Tenant shall have no right to regain the new keys to the Premises or the right of possession unless
approved in writing by Landlord on terms acceptable to Landlord in its sole discretion. If Landlord elects, it may lease the Premises to a replacement tenant on such terms as Landlord shall deem
advisable and receive all resulting rent. Tenant agrees to pay to Landlord on demand any deficiency that may arise by reason of such releasing for the remainder of the Lease term. In determining such
deficiency, Landlord shall be entitled to charge Tenant with all related costs and damages including but not limited to the following: (i) all costs of reentry, cleaning, repair, restoration or
redecoration necessary to prepare the Premises for the releasing, (ii) all brokers commissions due in connection with releasing, (iii) attorneys fees charged in connection with the
Tenants default, and (iv) all Basic Rental and other charges due under this Lease. Credit will be given toward Tenant's delinquency to the extent of net cash proceeds of the releasing only to
the extent actually received by Landlord for a period of time that is within the term of this Lease.

(c)Enter upon the Premises by force if necessary, without being liable for prosecution or any claim for damages, and do
whatever Tenant is obligated to do under the terms of this Lease; and Tenant agrees to reimburse Landlord on demand for any expenses which Landlord may incur in thus effecting compliance with Tenant's
obligations under this Lease, and Tenant further agrees that Landlord shall not be liable for any damages resulting to the Tenant from such action.

No
re-entry or taking possession of the Premises by Landlord shall be construed as an election on its part to terminate this Lease, unless an express written notice of such
intention is given to Tenant. Notwithstanding any such re-entry or taking possession and releasing, Landlord may at any time thereafter elect to terminate this Lease for a previous
default. Pursuit of any of the foregoing remedies shall not preclude pursuit of any of the other remedies listed in this Lease or any other remedies provided by law. Pursuit of any remedy under this
Lease shall not constitute a forfeiture or waiver of any rent due to Landlord or of any damages accruing to Landlord by reason of the violation of any portion of this Lease. Landlord's acceptance of
any payment following an event of default shall not be construed as Landlord's waiver of such event of default and shall not constitute a reinstatement of this Lease or of the right to possession
unless Landlord specifically states in writing the election to do so. No waiver by Landlord of any violation or breach of this Lease shall constitute a waiver of any other violation or breach of this
Lease. Forbearance by Landlord to enforce one or more of its rights under this Lease shall not be deemed or construed to constitute a waiver of any other violation, default or breach of this Lease. If
Landlord at any time terminates this Lease or the right to possession for any
default, in addition to any other remedy Landlord may have, Landlord may recover from Tenant all damages Landlord may incur by reason of such default including the cost of recovering the Premises and
the loss of rental for the remainder of the Lease term.

22.Surrender of Premises.No act or thing done by the Landlord
or its agents during the term of this Lease shall be deemed an acceptance of a surrender of the Premises or a cancellation of this Lease, and no agreement to accept a surrender of the Premises or
cancellation of this Lease shall be valid unless it is in a writing signed by the Landlord and specifically stated to be an acceptance of surrender of the Premises or Lease cancellation.

23.Attorney's Fees.If Landlord elects to utilize an attorney
to enforce any of Tenants obligations under this Lease then Tenant agrees in each and any such case to pay to Landlord the reasonable attorneys fees in connection with the matter. Matters for which an
attorney may be employed include the following: (i) Collection of any sum owed under this Lease such as Basic Rental; (ii) eviction or removal of Tenant from the Premises;
(iii) action to compel Tenant to comply with the terms of this Lease; (iv) actions to perfect and enforce Landlord's Liens.

24.Landlord's Lien.In addition to the statutory Landlord's
lien, Landlord shall have, at all times, a valid security interest to secure payment of: (i) all rentals and other sums of money due from Tenant under this Lease, (ii) any damages or
loss which Landlord may suffer by reason of the breach by Tenant of this Lease. Landlord's lien shall apply to (i) all equipment, fixture, furniture and improvements of Tenant now or later
situated on the Premises (subject to any purchase money security interests for such items), and (ii) all proceeds from such property. In event of default, all property subject to Landlords lien
shall not be removed from the Premises without the consent of Landlord until the default is fully cured. In event of default, Landlord may, in addition to any other remedies in this Lease, enter the
Premises and take possession of any and all property subject to Landlords lien, without liability for trespass or conversion. After taking possession of such property, Landlord may sell the same at
public or private sale, (whether or not the property is present at the sale), after giving Tenant reasonable notice of the time and location of any such sale is to be conducted. Landlord or its
agents, vendors or assigns may purchase the property at the sale. Unless otherwise mandated by law, and without excluding any other manner of giving Tenant reasonable notice, the requirement of
reasonable notice shall be met if such notice is given in the manner prescribed in paragraph 27 of this Lease at least five (5) days before the time of sale. The proceeds from any such
disposition, less any and all expenses connected with the taking of possession, holding and selling of the property (including reasonable attorneys' fees and other expenses), shall be applied as a
credit against the Tenants financial obligations under this Lease. Any surplus shall be paid to Tenant or as otherwise required by law; Tenant shall promptly pay any deficiencies. Upon request by
Landlord, Tenant agrees to execute and deliver to Landlord a financing statement in form sufficient to perfect the security interest of Landlord in the aforementioned property under the provisions of
the Uniform Commercial Code in force in the State of Texas. Landlord retains its statutory lien in addition to the lien created by this paragraph.

25.Mechanic's Liens:Tenant will not permit any mechanic's lien
or liens to be placed on any part of the Premises as a result of any work performed, materials furnished or obligation incurred by or at the request of Tenant. Tenant shall cause any such lien to be
removed within twenty (20) days after written notice from Landlord. If Tenant does not timely clear any such lien, Landlord, at its sole option, may pay whatever sums are necessary to discharge
the lien. Any amounts so paid (including expenses and interest), shall be immediately due from Tenant to Landlord as Additional Rental. Interest shall accrue on amounts so paid by Landlord until
repaid by Tenant at the lesser of the maximum lawful contract rate, or 18% per annum. Landlord has no obligation to inquire into the validity of any lien or the amounts of the underlying obligation
that is the basis of the lien.
