WITNESSETH:

SEC. 1.    LEASED PREMISES:In consideration of the mutual covenants set forth herein, Landlord hereby leases to
Tenant and Tenant hereby leases from Landlord for the rental and on the terms and conditions hereinafter set forth approximately 25,140 square feet of rentable space as indicated on the plan attached
hereto as EXHIBIT "A" and known as Suite 180 (the "Premises") in the office and warehouse building (the "Building") located at 9300 United Drive, in the city of Austin, Travis County, Texas. The
Building is part of a multi-building complex (the "Project"), which is located on the land (the "Land") more particularly described on EXHIBIT "B" attached hereto. The Premises, Building, Project and
Land together with all improvements (including, without limitation, all parking facilities) thereon are herein collectively called the "Property".

It
is agreed that the total rentable area of the Project is 121,870 square feet and that the Premises (and Tenant's pro rata share for Additional Rental purposes) is agreed to be 20.63%
thereof. It is agreed that the total rentable area of the Building is 50,210 square feet and that the Premises (and Tenant's pro rata share of the Building for Additional Rental purposes) is agreed to
be 50.07% thereof. All categories of Additional Rental shall be based on the prorations in this paragraph except for water and wastewater service to the Building which shall be fully charged to the
tenants of the Building regardless of the occupancy rate of the Building.

SEC. 2.    TERM:Subject to the conditions set forth herein, and in any exhibit or addendum hereto, signed by both
parties, the term of this Lease shall begin on the earlier of the date that Tenant actually occupies the Premise or March 1, 2001 ("Commencement Date") and shall end at midnight on
February 28, 2006, subject to delay as provided in the Work Letter attached hereto as EXHIBIT "G". If the Commencement Date begins prior to March 1, 2001, Base Rental as hereinafter
defined will not be charged to Tenant prior to March 1, 2001. Additional Rental as hereinafter defined will be charged to Tenant from the Commencement Date of the Lease however.

SEC. 3.    USE:The Premises shall be used and occupied by Tenant solely for office, wholesale sales, shipping and
warehouse purposes and for no other purpose. The office area of the Premises may be used only for general office purposes, and not for storage, loading, shipping or other warehouse-type
purposes. No manufacturing operations may be conducted at the Premises. For this purpose, manufacturing shall be defined as production of a tangible product for sale at the wholesale or retail level.
The term manufacturing shall not include light assembly or construction conducted in connection with Tenant's current business activities. It is further agreed that operation of a Test Lab shall not
be construed as manufacturing. No vehicle maintenance or servicing may take place on the Premises or the Project.

SEC. 4.    ADVANCE AND SECURITY DEPOSIT:A security deposit of $32,436.00 ("Security Deposit") and $37,464.00
representing Base Rental and Additional Rental due under this Lease for the first full month of the term of this Lease is due from Tenant on Lease execution date. Upon the occurrence of any event of
default by Tenant, Landlord may, from time to time with prior written notice, without prejudice to any other remedy, use the Security Deposit to the extent necessary to satisfy delinquent Rent or to
cure any Tenant default or to compensate Landlord for any loss or damage which Landlord may suffer by reason of Tenant's default. If any portion of the Security Deposit

1

---

is so used or applied, Tenant shall, upon demand therefore, deposit cash with Landlord in an amount sufficient to restore the Security Deposit to its original amount and Tenant's failure to do so
shall constitute a default hereunder by Tenant. If Tenant shall fully and faithfully perform every provision of this Lease to be performed by it, the Security Deposit shall be returned to Tenant
within sixty (60) days after termination of this Lease.

SEC. 5.    BASE RENTAL:As part of the consideration for the execution of this Lease, Tenant agrees to pay as "Base
Rental", the total sum listed on Exhibit D payable at the office of Landlord in monthly installments, as shown on Exhibit D each in legal tender of the United States of America, in
advance, without demand and without deduction, on the first day of each calendar month during their term hereof: provided, however, that if the term of this Lease commences on a date other than the
first day of a calendar month, the first rental payment, to be made on Lease execution shall be the rental for one full calendar month plus the pro rated rental remainder for the calendar month in
which the Lease term commences.

SEC. 6.    ADDITIONAL RENTAL:In addition to the Base Rental, as specified in this Lease, Tenant agrees to pay to
Landlord as additional rent ("Additional Rental) an amount equal to Tenant's pro rata share of the Operating Expenses (as hereinafter defined) for each calendar year during the term of this Lease.
Tenant's liability for Additional Rental for any partial year during the term of this Lease shall be prorated based upon the ratio of the number of days within the term of this Lease as compared to
the total number of days in such year.

A.    Operating Expenses:For the purposes of determining Additional Rental, "Operating Expenses" shall mean all of
Landlord's costs and expenses paid or incurred in operating and maintaining the Property for a particular calendar year or portion thereof, as determined by Landlord; provided, however, that Operating
Expenses shall not include any expenses otherwise the obligation of the Tenant under the other terms of this Lease.

Operating
Expenses shall include, without limitation:



2

---



Operating
Expense Exclusion. Notwithstanding anything to the contrary in this Lease, Operating Expenses shall not include, (i) the wages and benefits of any on-site
employees above the level of Building manager; (ii) the wages and benefits of any employee who does not devote substantially all of his or her time to the Building unless such wages and
benefits are allocated to, reflect the actual time
spent on operating and managing the Building vis-à-vis time spent on matters unrelated to operating and managing the Building.



B.    Monthly Payment of Estimated Additional Rental:Tenant's proportionate share of Operating Expenses for the
remainder of the calendar year after the Commencement Date and for each subsequent calendar year shall be estimated by Landlord, and written notice thereof shall be given to Tenant. Upon receipt of
said written notice from Landlord, the estimated Additional Rental shall be due and payable as herein provided. For any such remainder of the calendar year after the Commencement Date, Tenant agrees
to pay Landlord each month, at the same time the Base Rental is due, an amount equal to the amount of such estimated monthly Additional Rental for the remainder of such calendar year, and during each
calendar year thereafter Tenant agrees to pay Landlord each month, at the same time the Base Rental is due, an amount equal to one-twelfth (1/12) of the estimated annual
Additional Rental due.

C.    Annual Adjustment of Additional Rental:Within seventy-five (75) days after the end of
each calendar year, Landlord shall prepare and deliver to Tenant a statement showing Tenant's total amount of Additional Rental. Within thirty (30) days after receipt of the aforementioned
statement, Tenant agrees to pay Landlord, or if Tenant has overpaid, Landlord shall credit against the next Additional Rental payment or payments due from Tenant, as the case may be, the difference
between Tenant's actual Additional Rental due for the preceding calendar year and the estimated Additional Rental paid by Tenant during such year. Upon completion of the year end statement of
Additional Rental, Landlord may revise the estimated Additional Rental for the then current year by giving Tenant written notice to that effect, and thereafter Tenant agrees to pay Landlord, in each
of the remaining months of such year, an additional amount equal to the amount of such annual increase or decrease in the estimated Additional Rental divided by the number of months remaining in such
year. Tenant shall have the right to audit Landlord's Additional Rental charges, at Tenant's expense, within sixty (60) days of receipt by Tenant of any particular year-end
accounting for Additional Rental. If any errors are found resulting in an overcharge to the Tenant, Landlord will reimburse the overcharge to the Tenant and if the overcharge is more than 5% of the
yearly Additional Rental charged to Tenant, Landlord will reimburse to Tenant the reasonable costs of the audit.

SEC. 7.    RENT:The Base Rental, Additional Rental, and all other sums required to be paid by Tenant hereunder,
are sometimes collectively referred to as, and shall constitute, "Rent".

Rent
shall be paid by Tenant when due, or if paid by mail the rent must be postmarked before the due date and received within five (5) business days of due date, without prior
demand therefore and

3

---

without deduction or set off unless otherwise specifically provided herein, at the office of the Landlord or at such other place as Landlord may designate from time to time.

In
the event any installment of Base Rental, Additional Rent or other amount due from Tenant to Landlord under this Lease shall not be paid when due, a late charge of five cents ($.05)
per each dollar so overdue may be charged by Landlord for the purpose of defraying Landlord's administrative expenses incident to the handling of such overdue payments, and Tenant agrees to pay such
Rent to Landlord upon demand, unless the delay is caused by United States Postal Service performance outside of Tenant's control.

SEC. 8.    PAYMENT FOR OTHER SERVICES:Tenant agrees to pay to Landlord all charges for any services, goods, or
materials furnished by Landlord at Tenant's request which are not required to be furnished by Landlord under this Lease, within 10 days after written receipt of Landlord's request for payment.

SEC. 9.    TENANT'S OCCUPANCY AND USE:The Premises shall be used solely for the purpose specified in
Section 3. Tenant will not use, occupy or permit the use or occupancy of the 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 Project; or keep any substance or carry on or permit any operation which might emit offensive odors or conditions into other portions of the Property or use any
apparatus which might make undue noise or set up vibrations in the Project; or permit anything to be done which would increase the fire and extended coverage insurance rate on the Project or contents,
and if there is any increase in such rate by reason of acts of Tenant, then Tenant agrees to pay such increase promptly upon demand by Landlord. Payment by Tenant of any such rate increase shall not
be a waiver of Tenant's duty to comply herewith. Tenant agrees to comply with all requirements of the Americans with Disabilities Act (Public Law 101-336 July 26, 1990)) and the
Texas Architectural Barriers Act (Article 9102, Tex. Rev. Civ. St. (1991)) applicable to the Premises and applicable to the Project to the extent necessary to accommodate any special
requirements of Tenant's employees, invitees and customers not applicable to the other tenants in the Project. Tenant acknowledges that it shall be wholly responsible for any accommodations or
alterations which need to be made to the Premises to accommodate Tenant's employees, customers and invitees and for making any additional accommodations or alterations which need to be made to the
Project to accommodate any special requirements of Tenant's employees, invitees and customers not applicable to the other tenants in the Project.Tenant agrees to indemnify and
hold Landlord harmless from any and all expense (including, without limitation, attorneys' fees), liabilities, costs, or damages suffered by Landlord as a result of Tenant's failure to comply with its
obligations under this Section 9.

has, prior to the execution hereof, fully inspected the Premises and that it has made, performed, obtained and received all studies, inspections, reports, diagnoses and tests that Tenant desires
relative to the Premises and Tenant's proposed business use of the Premises. Tenant understands and agrees that it is accepting the Premises in its present "AS-IS", "WHERE-IS"
condition, "WITH ALL FAULTS", subject to the provisions of Section 16 and Exhibit G herein and also subject to any non-cosmetic, significant latent construction defects in
any other component of the Premises in existence at the Commencement Date which reveal themselves on or before May 31, 2001. Tenant warrants that it used all due diligence in conducting all
studies, inspections, diagnoses and tests on the Premises that Tenant deemed necessary or appropriate. Tenant acknowledges that Landlord has not made and does not make, and Landlord hereby disclaims,
any and all warranties, express or implied, which in any way relate to the Premises or the condition thereof, including without limitation any implied warranty of suitability or habitability. Tenant
further understands that Landlord has relied

4

---

upon Tenant's having made all inspections Tenant desired prior to leasing the Premises from Landlord, and that but for such inspections by Tenant, Landlord would not have leased the Premises to
Tenant.

SEC. 11.    LANDLORD'S RIGHT OF ACCESS:Landlord or its authorized agents shall at any and all reasonable times,
with reasonable notice to Tenant (except during an emergency), have the right to enter the Premises to inspect the same, to supply any service Landlord deems necessary to provide hereunder, to show
the Premises to prospective purchasers or tenants, improve or repair the Premises or any other portion of the Property all without being deemed guilty of an eviction of Tenant and without abatement of
Rent, and may for that purpose erect scaffolding and other necessary structures where reasonably required by the character of the work to be performed, provided the business of Tenant shall be
interfered with as little as is reasonably practicable. Tenant hereby waives any claim for damages for any injury or inconvenience to or interference with Tenant's business, any loss of occupancy or
quiet enjoyment of the Premises, and any other loss occasioned thereby unless due to Landlord's willful misconduct or gross negligence. Landlord shall have the right to use any and all means which
Landlord may deem proper to open any door(s) in an emergency without liability therefore.

SEC. 12.    QUIET POSSESSION:Upon Tenant's paying the Rent reserved hereunder and observing and performing all of
the covenants, conditions and provisions on Tenant's part to be observed and performed hereunder, Tenant shall have the quiet possession of the Premises for the entire Term hereof, subject to all of
the provisions of this Lease, and subject to the terms of all restrictions, easements and other matters of record applicable to the Property.

SEC. 13.    UTILITIES:Landlord agrees to provide normal utility connections to the building in which the Premises
are located for water, electricity, telephone service and sewage service to the Premises. Tenant shall arrange for and promptly pay to the applicable utility company all charges for electricity,
telephone service, sewage service and other utilities furnished to the Premises, including, but not limited to initial connection charges. Tenant shall pay for all wiring, risers, transformers,
electrical panels, air conditioning or beating equipment and other item necessary, or as required by Landlord (in Landlord's reasonable discretion), to accommodate Tenant's design loads and capacities
in the
Premises, or as required by the utility company, including the cost of installation and maintenance thereof. Notwithstanding the foregoing, Landlord may refuse to install and withhold consent for
Tenant's installation of any wiring, risers, transformers, electrical panels, or air conditioning or heating equipment if, in Landlord's sole reasonable judgment, the same are not necessary or would
cause damage or injury to the Project or the Premises, or cause or create a dangerous or hazardous condition or entail excessive or unreasonable alterations or repairs to the Project or the Premises
or would interfere with or create or constitute a disturbance to other tenants or occupants of the Project. In no event shall Landlord incur any liability for Landlord's refusal to install, or
Landlord's withholding of consent for Tenant's installation of, any such facility or equipment. Landlord may, if it so elects, furnish one or more utility services to the Tenant, and in such event
Tenant shall purchase the use of such services as are tendered by Landlord and shall pay on demand as additional Rent the rates established therefore by Landlord which shall not exceed the rates which
would be charged for the same services if furnished directly by the local public utility company supplying such service. Unless caused by the gross negligence or willful misconduct of Landlord,
Landlord 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 the Tenant, work an abatement of Rent,
or relieve Tenant from the operation of any covenant or agreement; but in the event of any failure, stoppage or interruption thereof, Landlord shall use reasonable diligence to cause such service to
be resumed promptly after written notice to Landlord of such failure, stoppage or interruption.

SEC. 17.    LIENS BY TENANT:Tenant shall keep the Premises free from any liens arising out of any work performed,
materials furnished, or obligations incurred by or for Tenant. In the event that Tenant shall not, within ten (10) days following the imposition of any such lien, cause the same to be released
of record by payment or posting of a proper bond, Landlord shall have, in addition to all other remedies provided herein and by law, the right but not the obligation, to cause the same to be released
by such means as it shall deem proper, including payment of or defense against the claim giving rise to such lien. All sums paid by Landlord and all expenses incurred by it in connection therewith
shall create automatically an obligation of Tenant to pay, on demand, an equivalent amount together with interest at the rate of 12% per annum. No work which Landlord permits Tenant to perform in the
Premises shall be deemed to be for the immediate use and benefit of Landlord so that no mechanics or other lien shall be allowed against the estate of Landlord by reason of its consent to such work.

SEC. 18.    SUBLETTING AND ASSIGNING:Tenant shall not assign this lease, or allow it to be assigned, in whole or
in part, by operation of law or otherwise, or mortgage or pledge the same, or sublet the Premises, or any part thereof, without the prior written consent of Landlord, which consent shall not be
unreasonable withheld, and in no event shall any such assignment or sublease ever release Tenant from any obligation or liability hereunder. No assignee or sublessee of the Premises or any portion
thereof may assign or sublet the Premises or any portion thereof. Landlord shall not collect any rents or other payments from any party other than Tenant unless Tenant is in default under the terms of
the Lease. Any collection by Landlord from any approved assignee or sublessee or any other party on behalf of Tenant's account shall not be construed to constitute a novation or a release of Tenant
from further performance of its obligations under this Lease.

If
the Tenant desires to assign or sublet all or any part of the demised Premises, it shall submit all necessary information as may be required by Landlord at least sixty
(60) days in advance of the date on which Tenant desires to make such assignment or sublease, and shall submit a copy of the proposed assignment or sublease. Within fifteen (15) days
after Landlord's receipt of Tenant's proposed assignment or sublease and the other information, Landlord shall have the option to:

(a)  Cancel
the Lease as to the Premises or portion thereof proposed to be assigned or sublet; or

(b)  Consent
to the proposed assignment or sublease. Should Tenant sublease space for an amount that is in excess of the agreed rental rate in this lease, Landlord shall have
the right to 50% of such excess, or should Tenant sublease space for less than the agreed rental rate in this Lease, Tenant shall be obligated to Landlord for the difference between the agreed upon
rental rate in this Lease and the rate in the sublease agreement; or

---

(c)  Refuse
its consent to the proposed assignment or sublease but allow Tenant to continue in the search for an assignee or sublessee that may be acceptable to Landlord.

Notwithstanding
anything herein to the contrary, Landlord will allow Tenant to sublease, without Landlord's prior written consent, to any subsidiary or affiliated corporation of which
Tenant owns all or substantially all of its assets or any parent corporation which owns all of Tenant. In no event will any such sublease ever release Tenant from any obligation or liability
hereunder. For the purposes of this Lease, the sale of fifty percent (50%) or more of the capital stock or other equity interest in Tenant shall be deemed an assignment of this Lease, except for the
sale of capital stock or other stock in an initial or subsequent public equity offering.

SEC. 19.    FIRE AND CASUALTY:The parties hereto mutually agree that if the Premises or Project are partially or
totally destroyed by fire or other casualty, then Landlord may, at Landlord's option, repair and restore the Premises and Project, to substantially the same condition in which the Premises and Project
were before such damage, or it may terminate the Lease; provided, however, that in the event the Premises or Project are completely destroyed or so badly damaged that in Landlord's reasonable
estimation, repairs cannot be commenced within ninety (90) days and completed within six (6) months thereafter, then Landlord shall so notify Tenant and this Lease shall be terminable as
of the date of the occurrence of the damage or destruction, by either party hereto by serving written notice upon the other within thirty (30) days after such notice; and provided further, that
in any event if repairs have not been commenced within ninety (90) days from the date of said damage and thereafter completed within nine (9) months from commencement, this Lease may be
immediately terminated by Tenant as of the date of occurrence of the damage or destruction, by serving notice upon the Landlord at any time prior to commencement of construction if the grounds for
termination is failure to commence construction within ninety (90) days, or at any time prior to completion of construction if termination is based upon the failure to complete construction
within nine (9) months.

In
the event the Premises are completely destroyed or so damaged by fire or other casualty that it cannot reasonably be used by Tenant for the purposes herein provided and this Lease is
not terminated as above provided, then there shall be a total abatement of Rent until the Premises are made usable. In the event the Premises are partially destroyed or damaged by fire or other hazard
so that such Premises can be only partially used by Tenant for the purpose herein provided, then there shall be a partial abatement in the Rent corresponding to the time and extent which the Promises
cannot be used by Tenant. Landlord shall not be obligated in any way or manner to insure any personal property (including, but not limited to, any fixtures, furniture, machinery, goods, supplies or
improvements) of Tenant or which Tenant may have upon or within the Premises or any fixtures installed by or paid for by Tenant upon or within the Premises.

Except
as provided in Section 20 below, if any portion of the, Property shall be damaged by fire or other casualty resulting from the fault or negligence of Tenant, or the agents,
employees, licensees, or invitees of Tenant, such damage shall be repaired by and at the expense of Tenant under the direction and supervision of Landlord, and Rent shall continue without abatement.

SEC. 20.    WAIVER OF SUBROGATION:Landlord and Tenant hereby waive any rights each may have against the other, on
account of any loss or damage occasioned to Landlord or Tenant, as the case may be, their respective property, the Premises, its contents or to the other portion of the Property arising from any risk
covered by valid and enforceable insurance, to the extent of such coverage. Landlord and Tenant each agree to cause an endorsement to be furnished to their respective insurance policies recognizing
this waiver of subrogation, or take such other action as to reasonably requested by the other party to verify the effectiveness of this waiver of subrogation.

11

---

event this Lease shall terminate as of the date when physical possession of such portion of the Project or Premises is taken by the condemning authority. If this Lease is not so terminated upon any
such taking or sale, the Base Rental payable hereunder shall be diminished by an equitable amount, and Landlord shall, to the extent Landlord deems feasible, restore the Project and the Premises to
substantially their former condition, but such work shall not exceed the scope of the work done by Landlord in originally constructing the Project and installing improvements in the Premises, nor
shall Landlord in any event be required to spend for such work an amount in excess of the amount received by Landlord as compensation for such taking. All amounts awarded upon a taking of any part or
all of the Property, Project or the Premises shall belong to Landlord, and Tenant shall not be entitled to and expressly waives all claims to any such compensation.

SEC. 29.    TAXES ON TENANT'S PROPERTY:Tenant shall be liable for and shall pay, prior to their becoming

estate taxes or assessments which may be levied against the Property by reason of Tenant's fixtures and/or furnishings in the Premises.

SEC. 30.    SIGNS:No signs of any kind or nature, symbol or identifying mark shall be put on the Project, the
Property, in the halls, elevators, staircases, entrances, parking areas or upon the doors or walls, whether plate glass or otherwise, of the Premises nor within the Premises so as to be visible from
the public areas or exterior of the building in which the Premises are located, without prior written approval of Landlord which consent shall not be unreasonably withheld. All signs or lettering
shall conform in all respects to the sign and/or lettering criteria established by Landlord.

SEC. 31.    PARKING:Subject to the following terms and conditions, Tenant shall have a non-exclusive
license to use 91 parking spaces associated with the Project. Tenant's right to such parking spaces are subject to Landlord's rights to grant other tenants of the Project the rights to parking spaces
associated with the Project. Landlord reserves the right from time to time to assign, or re-assign, the location of such parking spaces in any manner that Landlord in Landlord's sole
discretion deems beneficial to the operation of the Project, provided that Tenant shall always have the non-exclusive license to use 91 parking spaces associated with the Project. Should
Landlord, pursuant to this right, re-assign spaces to reserved or other preferential parking associated with the Building, Tenant shall be entitled to a portion of such spaces based on its
rentable square footage as a percentage of total Building square footage. Tenant agrees that it will employ its best efforts to prevent the use by Tenant's employees and visitors of parking spaces
allocated to other tenants. Landlord reserves the right to promulgate rules and regulations for the use of all parking areas at any time during the term of this Lease. All motor vehicles (including
all contents thereof), shall be parked in such spaces at the sole risk of Tenant, its employees, agents, invitees and licensees, it being expressly agreed and understood that Landlord has no duty to
insure any of said motor vehicles (including the contents thereof), and that Landlord it not responsible for the protection and security of such vehicles, or the contents thereof. Landlord shall have
no liability whatsoever for any property damage and/or personal injury which might occur as a result of or in connection with the parking of said motor vehicles in any of the parking spaces. Nothing
herein shall be deemed to create a bailment between the parties hereto, it being expressly agreed and understood that the only relationship created between Landlord and Tenant hereby is that of
licensor and licensee, respectively.

SEC. 32.    RULES AND REGULATIONS:Such reasonable rules and regulations applying to all Tenants in the Project as
may be adopted by Landlord for the safety, care, cleanliness, preservation of good order, or operation of the Premises, the Project and the Property, are hereby made a part hereof and Tenant agrees to
comply with all such rules and regulations. Landlord shall have the right at all times to change any of the rules and regulations or to amend them in any manner deemed reasonable by the Landlord. All
changes and amendments will be sent by Landlord to Tenant in writing and shall be thereafter carried out and observed by Tenant (See "Rules and Regulations" attached hereto as EXHIBIT "C").

SEC. 33.    FORCE MAJEURE:In the event Landlord shall be delayed, hindered, or prevented front the performance of
any act required hereunder by reason of acts of God, strikes, lockouts, labor disputes, labor troubles, inability to procure materials, failure of power, restrictive governmental laws or regulations,
riots, insurrection, war or other cause not within the reasonable control of Landlord, then the performance of such act shall be excused for the period of the delay and the period for the performance
of any such act shall be extended for a period equivalent to the period of such delay.

SEC. 34.    HOLDING OVER:In the event Tenant, or any party claiming under Tenant, retains possession of the
Premises after the expiration or earlier termination of this Lease, such possession shall be an unlawful detainer, and no tenancy or interest shall result from such possession; such parties shall be
subject to immediate eviction and removal, and Tenant or any such party shall pay Landlord as Rent for the period of such hold-over an amount equal to 150% of the Rent in effect at the
time of such termination or expiration.

Tenant
will vacate the Premises and deliver same to Landlord immediately upon Tenant's receipt of notice to do so from Landlord. The Rent during such hold-over period shall
be payable to Landlord on demand. No holding over by Tenant, whether with or without consent of Landlord, shall operate to extend this Lease.

SEC. 35.    NON-WAIVER:No waiver by Landlord of any provision of this Lease or of any breach by Tenant
hereunder shall be deemed to be a waiver of any other provision hereof, or of any subsequent breach by Tenant of the same or any other provision. Landlord's consent to or approval of any act by Tenant
requiring Landlord's consent or approval shall not be deemed to render unnecessary the obtaining of Landlord's consent to or approval of any subsequent act of Tenant. No act or thing done by Landlord
or Landlord's agents during the term of this Lease shall be deemed an acceptance of a surrender of the Premises, unless done in writing signed by Landlord. The delivery of the keys to any employee or
agent of Landlord shall not operate as a termination of the Lease or a surrender of the Premises. The acceptance of any Rent by Landlord following a breach of this Lease by Tenant shall not constitute
a waiver by Landlord of such breach or any other breach unless such waiver is expressly stated in writing signed by Landlord.

SEC. 36.    SUBORDINATION AND ATTORNMENT:

A.    Subordination:This Lease shall be subject to and subordinate to any lease wherein Landlord is the lessee and
to the lien of any and all mortgages or deeds of trust, regardless of whether such lease, mortgages or deeds of trust now exist or may hereafter be created with regard to all or any part of the
Project or the Property, or both, and to any and all advances to be made thereunder, and to the interest thereon, and all modifications, consolidations, renewals, replacements and extensions thereof.
Tenant also agrees that any lessor or mortgagee may elect to make this Lease prior and superior to any lease or lien of its mortgage or deed of trust. Any such election must be in writing and shall be
effective when filed in the Real Property Records of the County in which the Project is located. In the event of such election, this Lease shall be deemed prior and superior to the said lease or lien
of said mortgage or deed of trust, whether this Lease is dated prior to or subsequent to the date of said lease, mortgage or deed of trust.

B.    Attornment:In the event of any proceedings brought for the foreclosure of any mortgage or deed of trust
covering the Property, or any part thereof, or in the event of the exercise of a power of sale pursuant thereto and upon the written request of a purchaser at such foreclosure proceedings, Tenant
shall, at the request of such purchaser, attorn to and recognize such purchaser as Landlord under this Lease.

C.    Instruments of Confirmation:The above subordination and attornment clauses shall be
self-operative and no further instruments of subordination or attornment need be required by any mortgagee, trustee, lessor, purchaser or assignee. In confirmation thereof, Tenant agrees
that, upon ten

13

---

(10) days prior written notice from Landlord, or any such lessor or mortgagee, Tenant shall execute and deliver whatever instruments may be required for such purposes in order to carry out the
intent of this Section. In the event that Tenant should fail to execute and deliver such instruments in compliance with this Section, Tenant hereby irrevocably constitutes Landlord as its
attorney-in-fact to execute such instrument in Tenant's name, place and stead, it being agreed that such power is one coupled with an interest.

D.    Non-Disturbance Agreement:Upon written request by Tenant, Landlord agrees to request of any
existing lessor, mortgagee or lien holder, a non-disturbance agreement executed by such party, stating that so long as Tenant is not in default under this Lease, Tenant's leasehold estate,
and the right to the use, possession, tenancy and occupancy hereunder, shall remain undisturbed and survive any and all terminations of such Lease or foreclosures or conveyances in lieu thereof or
other actions taken or entered into to enforce any such lease, mortgage or deed of trust. Landlord shall have no obligation beyond the requesting of such non-disturbance agreement, and
shall not be in default hereunder in the event such lessor, mortgagee or other lien holder refuses to execute and deliver such non-disturbance agreement.

SEC. 37.    ENVIRONMENTAL COMPLIANCE:Other than incidentally in the course of Tenant's business or practice,
Tenant shall not use, and shall not permit any servant, licensee, employee, agent, or invitee to use any portion of the Premises or Project for the placement, storage, manufacture, disposal, or
handling of any "Hazardous Materials" (as herein defined). To the extent used in the course of Tenant's business or practice, Tenant shall manage, handle, and provide safeguards for the Premises,
the remainder of the Project, and all persons coming to the Premises, or to the Project, in accordance with all rules, regulations, orders, guidelines, or other instructions or directives of the
United States of America, any State, any political subdivision of' either of such governmental entities, or any other governmental entity having authority to regulate such Hazardous Materials. In the
event there is no entity with authority to regulate any portion of the Hazardous Materials used in the ordinary course of Tenant's practice, then Tenant agrees to handle, use, and dispose of such
Hazardous Materials in the same manner that a prudent person would handle the same, and consistent with standard industry practice. Tenant shall, upon Landlord's written request, provide Landlord with
a written list of any Hazardous Materials handled by it at the Premises as well as such other information as Landlord may request regarding such Hazardous Materials and Tenant's handling of the same.
In the event that Landlord shall reasonably determine that the handling by Tenant of any Hazardous Material shall pose an unacceptable risk to Landlord or its affiliates, Landlord reserves the right
to require additional liability insurance and/or bonding of Tenant's operations. In the event that Landlord shall elect to require such insurance or bonding of Tenant, Tenant shall be solely
responsible for obtaining same. Landlord may object at any time to Tenant's improper use, handling, disposal or record keeping practices concerning such Hazardous Materials and Tenant shall
immediately correct such practices as soon as receiving any notice of such concerns from Landlord (unless Tenant can demonstrate that such practices are proper under both current law and current,
customary industry practice). Notwithstanding the foregoing, Landlord shall be under no obligation to supervise Tenant's business, operations or procedures. Tenant shall be responsible for the costs
of any removal, abatement, or remediation of any Hazardous Materials placed, stored, manufactured, disposed of, or handled by Tenant or Tenant's servants, licensees, or any of Tenant's employees,
agents, or invitees, in the Premises or elsewhere on the Project. Such costs shall include, without limitation, the reasonable cost of any consultant retained by Landlord in connection with such work. Tenant shall indemnify
Landlord and hold Landlord harmless from and against any loss, cost, liability, or expense (including reasonable attorney's fees and court costs) arising
out of the placement, storage, manufacture, disposal, handling, removal, abatement, or remediation of any Hazardous Materials by Tenant, or any removal, abatement or remediation of any Hazardous
Materials required hereunder to be performed or paid for by Tenant, with respect to any portion of the Premises or Project, or arising out of any breach by Tenant of its obligations under this
Section 37.The provisions of this Section 37 shall survive the termination of this

enforced to the greatest extent permitted by law.

foregoing option, Tenant shall give Landlord written notice thereof at least nine (9) months prior to the beginning of the Renewal Term, in which event the Lease will be renewed at the Fair
Market Value Rent (hereinafter defined) as reasonably determined by Landlord and Tenant. In the event that a renewal agreement has not been executed at least six (6) months prior to Lease

space immediately contiguous to the Premises of this Lease. If Landlord has an acceptable bona fide offer for the space, Tenant's right to lease will be under the same terms and conditions as the
offer. Written acceptance or rejection of Tenant's right to lease must be received by Landlord within five (5) business days of receiving the option right and Tenant must execute the lease for
the space within ten (10) business days. If Tenant elects not to accept the offer, then this One-time Right of First Refusal will become null and void forevermore.

Upon
eight (8) months prior written notice, Tenant shall have the right to require Landlord to provide Tenant with up to twenty-one (21) Additional Parking
Spaces ("APS") on land owned by Bill Gaston, Inc. on property adjacent to the Project and to the south of the Project currently described as the portion of Lot 1, Block A, Research Interchange
Subdivision, Travis County, Texas not contained in the Project ("Phase 2"), provided Bill Gaston, Inc. or a related entity owns Phase 2 at the time of Tenant's exercise of this right. Upon
delivery of the APS, Tenant shall pay additional Rent in the amount of $50 per parking space leased. If Tenant ever reduces the number of APS it requires, Tenant will be limited to that number of APS
thereafter.

Upon
redevelopment of Phase 2, Landlord shall be allowed to cease leasing the APS to Tenant. Landlord will work cooperatively with Tenant to provide Tenant with up to 21 APS upon
completion of the redevelopment of Phase 2 under terms reasonably determined in Landlord's sole discretion taking into account the cost of development of the parking structures associated with the
redevelopment of Phase 2. If Tenant leases APS in the redevelopment of Phase 2, Tenant will be not be allowed to reduce the number of APS it leases during the term of this Lease or its renewal.

EXHIBIT G  WORK LETTER

It is agreed that Landlord will complete construction of the Premises leased by Landlord to Tenant in that certain Lease to which a copy of this Work Letter is
attached, in accordance with the following:

1.    Within
ten (10) working days of the execution of the Lease, Tenant shall provide to Landlord (a) a preliminary space plan showing all proposed interior
partitions, doors, plumbing fixtures and millwork and (b) preliminary specifications for all interior improvements and finishes. Such space plan and specifications shall be (a) prepared
by either Landlord's architect and engineer or an architect and engineer selected by Tenant, provided that the Tenant's architect and engineer must be previously approved in writing at Landlord's sole
discretion and Landlord's architect and engineer shall review the working drawings and specifications of materials at Tenant's expense, (b) in accordance with such specifications as Landlord
has established for the construction of all interior improvements within the Project (the "Building Standards") and (c) subject to approval by Landlord. Landlord shall have a period of five
(5) days after receipt of the preliminary space plan and specifications in order to approve or disapprove same. If Landlord shall disapprove Tenant's plans and specifications within such five
(5) day period and advise Tenant in writing of the changes which will be necessary in order for Landlord to approve same, Tenant shall make the changes in the preliminary space plan and
specifications required by Landlord and submit a revised preliminary space plan and specifications to Landlord not
later than five (5) days after receipt of Landlord's written comments thereon and/or requirements with respect thereto. Any delay occasioned as a result of Landlord's disapproval of Tenant's
plans and specifications shall not delay the Commencement Date under this Lease. In the event that Landlord fails to approve the originally submitted preliminary space plan and specifications within
the aforesaid five (5) day period or to disapprove same with comments and/or requirements with respect thereto having been submitted to Tenant by Landlord within such five (5) days,
Tenant shall have the right to give Landlord written notice of Landlord's failure to approve or disapprove Tenant's plans and specifications on or before the expiration of five (5) days
following the expiration of the aforesaid five (5) day period, and if Landlord shall not have responded to such notice from Tenant within five (5) days thereafter by enumerating reasons
for Landlord's disapproval of Tenant's plans and specifications, this Lease automatically shall be null and void and neither Landlord nor Tenant shall have any further rights or obligations hereunder.
When the preliminary space plan and specifications as revised are approved by Landlord, then the architect and engineer mutually selected by Tenant and Landlord, but under contract to Landlord, shall
commence the preparation of the construction documents for the Improvements. At such time as the construction documents are completed then Tenant and Landlord shall review same and each initial and
date the construction documents (the "Construction Documents").

2.    Landlord
shall obtain at least three (3) bids for the construction of the Improvements in accordance with the Construction Documents. The selection of the general
contractor to perform the construction of the Improvements shall made by Landlord with the consent of Tenant and shall be based on the following: (a) the contractor's qualifications and
experience, (b) the ability of the contractor to perform on the schedule and meet or exceed the projected commencement date and (c) the contractor's proposed contract amount. The cost of
the Improvements for the purpose of billing shall equal the cost to Landlord of constructing such Improvements (including the cost of supervision and coordination) plus the following amount: 4% if
Landlord employs a general contractor.

3.    Architectural
and engineering fees relating to the Premises (including any architectural and engineering fees incurred by Landlord in reviewing Tenant's working drawings
and specifications and in modifying Landlord's master working drawings to incorporate plans prepared by Tenant's architect or engineer, where an architect or engineer other than Landlord's architect
or engineer has prepared Tenant's working drawings and specifications) shall be paid by Tenant. All costs and expenses incurred in the construction of Improvements shall be borne by Tenant (and are
hereinafter referred to as

25

---

"Tenant's Costs"); provided, however, that Tenant shall receive an allowance (the "Allowance") of $703,920.00 to be credited against the billing costs of constructing the Improvements. Any excess
(the "Excess") of Tenant's Costs over the Allowance shall be payable as follows:



The
amounts payable hereunder shall constitute Rent due pursuant to the Lease at the times specified herein and failure to make any such payments when due shall constitute a default
under the Lease, entitling Landlord to all of its remedies thereunder, as well as all remedies otherwise available to Landlord.

The
Excess to be paid by Tenant shall be required to be at least $150,000.00. In the event that the Excess is less than $150,000.00, the amount of the difference (the
"Make-up Amount") shall be paid to Landlord by Tenant as soon as the final accounting is determined as in Section 3(c) herein. In the event that a Make-up Amount is due
and paid by Tenant, the remaining Base Rental shall be reduced by amortizing the Make-up Amount over the remaining primary Term of the Lease using an 11% amortization factor.

4.    If
Tenant requests any changes in the approved plans and specifications for the Improvements, Tenant shall present Landlord with revised plans and specifications. If
Landlord approves such changes, Landlord shall incorporate such changes in the Improvements; Landlord, however, may require, prior to proceeding with any changes, additional cash advances against the
Excess in the event Landlord determines that Tenant's proposed changes will increase the amount of such Excess.

5.    If
Tenant requests changes in the approved plans and specifications for the improvements and if such changes shall delay the work to be performed hereunder, or if Tenant
shall otherwise delay the completion of said work, including, without limitation, delay resulting from Tenant's failure to timely submit final working drawings and specifications of materials for
Landlord's approval, then, notwithstanding any provision to the contrary in the Lease, Tenant's obligation to pay rent hereunder shall nevertheless commence on the date in Section 2 of the
Lease and the Commencement Date under the Lease shall not be delayed as hereinafter provided. If by the Commencement Date specified in Section 2 of the Lease, the Premises have not been
substantially completed pursuant to the terms of this Work Letter, due to any cause other than delays caused by Tenant as provided above, then, as Tenant's sole remedy for the delay in Tenant's
occupancy of the Premises, the Commencement Date shall be delayed and the Rent under the Lease shall not commence until the earlier of actual occupancy by Tenant or substantial completion of the
Improvements.

6.    Within
seven (7) days after delivery of the Improvements to Tenant, Tenant shall have the right to submit a written "punch list" to Landlord, setting forth any
defective item of construction, and Landlord shall promptly cause such items to be corrected. During the first year of the term of this
Lease, Tenant shall give notice to Landlord whenever any defect becomes reasonably apparent, and Landlord will use reasonable efforts to enforce the warranties of the contractors.

7.    All
terms herein used shall have the same meaning as when used in the Lease.
