COMMERCIAL LEASE AGREEMENT    
  


        THIS LEASE AGREEMENT is entered into by and between: 


        1.    LANDLORD:    Jackson-Shaw Technology Center II Limited
Partnership


        2.    TENANT:    TestChip Technologies, Inc.


        3.    LEASED PREMISES:    In consideration of the rents, terms and covenants of this Commercial Lease Agreement (this
"Lease"), Landlord hereby leases to Tenant certain premises (the "Leased Premises") consisting of approximately 18,302 square feet within the 83,286
square foot building (the "Building") located at 2600 Technology Drive, Suite 600, Plano, Texas, 75074, together with the non-exclusive
light to use, in common with other tenants, the common areas of the Project, which are all areas neither exclusively leased to another tenant nor expressly reserved to or by Landlord. The land upon
which the Building is located is described in the attached Exhibit A and, together with the Building, landscaping, parking and driveway areas, sidewalks, and other improvements thereon, shall
be referred to in this Lease as the "Project." 


        4.    TERM:    


        (a)  The
term of this Lease shall be 66 months commencing on August 1,
2000, the "Commencement Date" and terminating on the last day of the 66th month following the Commencement Date (the "Termination Date"). This Commencement Date may be subject
to change, however, pursuant to Paragraph 4(c) below. 


        (b)  Tenant
acknowledges that it accepts the Leased Premises as suitable for Tenant's purposes subject only to Paragraph 4(c) below, if applicable. If this Lease is
executed before the Leased Premises become available for occupancy, or if Landlord cannot acquire possession of the Leased Premises prior to the Commencement Date stated above, Tenant agrees to accept
possession of the Leased Premises at such time as Landlord is able to tender the same, which date shall then be the Commencement Date of the Lease term. 



        (c)  Landlord
agrees to install at its cost and expense the improvements, if any, described in the plans and specifications described in Exhibit B. If such
improvements are not completed and the Leased Premises are not ready for occupancy on the Commencement Date stated above, other than as a result of the omission, delay or default by Tenant or anyone
acting under or on behalf of Tenant, the rent under this Lease shall not commence until substantial completion of the work described in said plans and specifications, and the Commencement Date of the
Lease term shall be the date of such substantial completion and Tenant secures Certificate of Occupancy. Landlord shall notify Tenant in writing as soon as such improvements are substantially
completed and ready for occupancy. If Tenant believes that such improvements have not been substantially completed as aforesaid, Tenant shall notify Landlord in writing of its objections within three
(3) days after receipt of the completion notice from Landlord. Landlord shall have a reasonable time after receipt of such notice (but in no event more than 10 days) in which to commence
such corrective action as may be necessary and shall notify Tenant in writing as soon as it deems such corrective action has been completed so that the Leased Premises are completed and ready for
occupancy. In the event of any dispute as to substantial completion or work performed or required to be performed by Landlord, the certificate of a registered architect shall be conclusive and binding
on all parties. 


        (d)  Tenant
acknowledges that no representations or promises regarding construction, repairs, alterations, remodeling, or improvements to the Leased Premises have been made
by Landlord, its agents, employees, or other representatives, unless such are expressly set forth in this Lease or any Exhibit hereto. Tenant is solely responsible for applying for and obtaining a
Certificate of Occupancy for the Leased Premises and will satisfy itself as to the business park restrictions and all zoning and similar restrictions and regulations prior to commencement of any
construction. Failure of Tenant to provide written notice of such objections prior to commencement of construction shall be deemed 


3





 




acceptance by Tenant. Tenant agrees that if its occupancy of the Leased Premises is delayed under the circumstances described in Paragraphs 4(b) and (c) above, this Lease shall nonetheless
continue in full force and effect. Adjustment of the rent commencement date as above provided shall constitute full settlement of all claims by Tenant against Landlord by reason of any such delay in
possession of the Leased Premises. Tenant's taking possession of the Leased Premises shall conclusively establish that the improvements, if any, to be made by Landlord under the terms of this Lease
have been completed in accordance with the plans and specifications therefor and that the Leased Premises are in good and satisfactory condition as of the date of Tenant's possession, unless Tenant
notifies Landlord in writing specifying any bona fide deficiencies after taking possession. Landlord shall use reasonable diligence to repair promptly such items but Tenant shall have no claim for
damages or rebate or abatement of rent by reason thereof. In conjunction with, or at any time after, the Commencement Date, Tenant shall, upon demand, execute and deliver to Landlord an Estoppel
letter (as referred to in paragraph 33 herein) to acknowledge the Commencement Date. 


        5.    BASE RENT AND SECURITY DEPOSIT:    



        (a)  Tenant
agrees to pay to Landlord the following rental amounts (sometimes referred to in this Lease as the "Base Rent" or "Base Rental"): months 1
and 4 through 6, $155,568.00 per year payable in monthly installments of $12,964.00 each, Months 7-66, $205,908.00 per year payable in monthly installments of $17,159.00 each. Landlord
agrees to waive months 2 and 3 of the primary Lease Term. Payment of rent is subject to proration for partial months and to adjustment for early or delayed
occupancy under the terms hereof, and, if the area of the Leased Premises is, on the Commencement Date, different than the area stated in Paragraph 3 above, then Base Rent shall be adjusted to
reflect the then applicable per square foot rate. On the commencement date of the Lease Agreement the first month's Base Rent shall be payable. All
subsequent payments shall be made to Landlord monthly, in advance, without demand, deduction or offset, in lawful money of the United States of America at the address stated below. All installments of
Base Rent shall be due and payable on or before the first (1st) day of each month during the Lease term. 


        (b)  Upon
the date Tenant executes the Lease Agreement, there shall be due and payable by Tenant a Security Deposit in the amount of  $17,159.00. Such deposit shall be held by Landlord (without any obligation to
pay interest thereon or segregate such money from Landlord's general funds
except as may be required by applicable law) as security for the performance of Tenant's obligations under this Lease. Tenant agrees to increase such Security Deposit from time to time so that it is
at all times equal to one monthly Base Rental installment plus the average monthly additional rentals arising pursuant to Paragraph 6 below. 


        Tenant
shall deposit cash with Landlord in an amount sufficient so to increase the Security Deposit to such amount within five (5) days after written demand by Landlord. It is
expressly understood that the Security Deposit is not an advance payment of rental or a measure of Landlord's damages in the event of Tenant's default under this Lease. Upon the occurrence of any
event of default by Tenant under this Lease, Landlord may, from time to time, without prejudice to any other remedy provided herein or provided by law, use, apply, or retain all or part of the
Security Deposit for the payment of (i) any Base Rent, (ii) additional rentals arising under Paragraph 6 below, and (iii) other sums due hereunder, including without
limitation any amount which Landlord may spend or become obligated to spend by reason of Tenant's default or to compensate Landlord for any damage, injury, expense or liability caused to Landlord by
such default or breach (all of which items (i), (ii) and (iii) are sometimes referred to in the aggregate as "Rent"). If any portion of the Security Deposit is so used or applied, Tenant
shall, within five (5) days after written demand thereof, deposit cash with Landlord in an amount sufficient to restore the Security Deposit to the amount required by this Paragraph. Tenant's
failure to do so shall be an event of default under this Lease. The balance of the Security Deposit shall be returned by Landlord to Tenant at such time after termination of this Lease that all of
Tenant's obligations have been fulfilled.

        (c)  Other
remedies for nonpayment of Rent notwithstanding, if the monthly Base Rental payment is not received by Landlord on or before the tenth (10th) day of the month for
which such rent is due, or if any other Rent payment due Landlord by Tenant hereunder is not received by Landlord within ten (10) days of the due date, a service charge of two hundred ($200.00)
dollars shall be additionally due and payable by Tenant as an administrative charge for the excess efforts necessitated by such tardiness in payment. Such service charge shall be cumulative of any
other remedies Landlord may have for nonpayment of Rent and other sums payable under this Lease. 


        (d)  If
three (3) consecutive monthly Base Rental payments or any ten (10) [in total, cumulative from the beginning of the Lease term]
monthly Base Rental payments during the Lease term (or any renewal or extension thereof) are not received by Landlord within ten (10) days of the due date, the Base Rent hereunder shall
automatically become due and payable by Tenant in advance in quarterly installments equal to three (3) months' Base Rent each. The first of such quarterly Base Rent payments shall be due and
payable on the first day of the next succeeding month and on the first day of every third (3rd) month thereafter. This remedy shall be cumulative of any other remedies of Landlord under this Lease for
nonpayment of Rent.

subtenant all rents due to Tenant. Landlord shall have a security interest in all property on the Leased Premises to secure payment of such sums. Any collection directly by Landlord from the assignee
or subtenant shall not be construed, however, to constitute a novation or a release of Tenant from the further performance of its obligations under the Lease. Notwithstanding the foregoing, it is
expressly agreed that if this Lease is assigned to any person or entity pursuant to the provisions of the Bankruptcy Code, 11 U.S.C. Sec. 101, et. seq., as amended (the "Bankruptcy Code"), any and all
monies or other considerations payable or otherwise to be delivered in connection with such assignment shall be paid or delivered to Lessor, shall be and remain the exclusive property of Landlord and
shall not constitute property of Tenant or of the estate of Tenant within the meaning of the Bankruptcy Code. Any and all monies or other considerations constituting Landlord's Property under the
preceding sentence not paid or delivered to Landlord shall be held in trust for the benefit of Landlord and be promptly paid or delivered to Landlord. Any person or entity to which this Lease is
assigned pursuant to the provisions of the Bankruptcy Code shall be deemed without further act or deed to have assumed all of the obligations arising under this Lease on and after the date of such
assignment. Any such assignee shall upon demand execute and deliver to Landlord an instrument confirming such assumption. 


        16.    ALTERNATIONS AND IMPROVEMENTS:    


        (a)  Tenant
shall not make or perform, or permit the making or performance of, any initial or subsequent tenant finish work or any alterations, installations, decorations,
improvements, additions or other physical changes in or about the Leased Premises that are structural in nature or exceed $5000.00 in costs (referred to collectively as "Alterations") without
Landlord's prior consent, such consent not to be unreasonably withheld. Landlord shall be under no obligation to allow Alterations of any kind and may withhold its consent without cause.
Notwithstanding the foregoing provisions or Landlord's consent to any Alterations, all Alternations shall be made and performed in conformity with and subject to the following provisions: All
Alternations shall be made and performed at Tenant's sole cost and expense in a good and workmanlike manner. Alternations shall be made only by contractors or mechanics approved by Landlord, such
approval not to be unreasonably withheld. Tenant shall submit to Landlord detailed plans and specifications (including architectural layout, mechanical and structural drawings) for each proposed
Alteration and shall not commence any such Alteration without first obtaining Landlord's written approval of such plans and specifications. Prior to the commencement of each proposed Alteration,
Tenant shall furnish to Landlord a certificate evidencing worker's compensation insurance coverage for all persons to be employed in connection with such Alterations, including those to be employed by
all contractors and subcontractors, and of comprehensive public liability insurance (including property damage coverage) in which Landlord, its agents, and any lessor under any ground or underlying
lease, and any mortgagee of the Building shall be named as parties insured, which policies shall be issued by companies and shall be in form and amounts satisfactory to Landlord and shall be
maintained by Tenant until the completion of such Alteration. Tenant shall cause its contractor and each subcontractor to provide Landlord with a Certificate of Completion of the Alterations and a
Bills Paid Affidavit and full Lien Waiver. Tenant shall, if required by Landlord at the time of Landlord's consent to the Alterations, agree to restore the Leased Premises at the termination of this
Lease to their condition prior to making such Alterations. All permits, approvals and certificates 


10





 


required by all governmental authorities shall be timely obtained by Tenant and submitted to Landlord. Notwithstanding Landlord's approval of plans and specifications for any Alterations, all
Alterations shall be made and performed in full compliance with all applicable laws, orders, rules, standards and regulations of Federal, State, County, and Municipal authorities, including, without
limitation, all directions, pursuant to law, of all public officers, and with all applicable rules, orders, regulations and requirements of the local Board of Fire Underwriters or any similar body
("Applicable Laws"). Landlord's approval shall not in any way be considered an indication that the plans and specifications comply with Applicable Laws. All materials and equipment to be incorporated
in the Leased Premises as a result of all Alterations shall be new and first quality. No such materials or equipment shall be subject to any lien, encumbrance, chattel mortgage or title retention or
security agreement. Whether such Alterations are being performed by Tenant in connection with Tenant's initial occupancy of the Leased Premises or subsequently, Tenant agrees to make proper
application for, and obtain, a Building Permit and a Certificate of Occupancy from the city in which the Leased Premises are located. Tenant shall furnish copies of such permit and certificate to
Landlord promptly after issuance of same. 


        (b)  All
appurtenances, fixtures, improvements, and other property attached to or installed in the Leased Premises, whether by Landlord or Tenant or others, and whether at
Landlord's expense or Tenant's expense, or the joint expense of Landlord and Tenant, shall be and remain the property of Landlord, except that any such fixtures, improvements, additions, and other
property which have been installed at the sole expense of Tenant and which are removable without material damage to the Leased Premises shall be and remain the property of Tenant. If no event of
default has occurred, Tenant may, and if Landlord so elects Tenant shall, remove any property belonging to Tenant at the end of the term hereof, and Tenant shall repair or, at Landlord's option, shall
pay to Landlord the cost of repairing any damage arising from such removal. Any replacements of any property of Landlord, whether made at Tenant's expense or otherwise, shall be and remain the
property of Landlord. 


        17.    CONDEMNATION:    


        (a)  If,
during the term (or extension or renewal) of this Lease, all or a. substantial part of the Leased Premises are taken for any public or quasi-public use under any
governmental law, ordinance or regulation, or by right of eminent domain or by private purchase in lieu thereof, and the taking would prevent or materially interfere with the then current use of the
Leased Premises, this Lease shall terminate and the Rent shall be prorated during the unexpired portion of this Lease effective on the date physical possession is taken by the condemning authority. 


        (b)  If
a portion of the Leased Premises is taken and this Lease is not terminated as provided in Paragraph 17(a) above, if condemnation proceeds are sufficient and if
restoration is feasible, Landlord may, at its option restore the Project (other than Alterations) in order to make it reasonably tenantable and suitable for Tenant's approved use. During such
restoration, Rent shall be reduced by the amount of business or rent interruption insurance proceeds actually received by Landlord. Upon completion of such restoration, the Rent payable under this
Lease during the unexpired portion of the term shall be adjusted to such an extent as may be fair and reasonable under the circumstances. 


        (c)  In
the event of such taking or private purchase in lieu thereof, Tenant may seek a separate award for any loss of improvements made or paid for by Tenant, its personal
property, and its moving expenses (so long as no such claim diminishes Landlord's claim or award), but all other claims of any nature shall belong to Landlord. In the event Tenant does not receive
such a separate award, Landlord shall be entitled to receive any and all sums awarded for the taking. 


        (d)  Notwithstanding
anything herein to the contrary, if the holder of any indebtedness secured by a mortgage or deed of trust covering the Building and/or Project requires
that the condemnation proceeds be applied to such indebtedness, then Landlord shall have the right to terminate this Lease by delivering written notice of termination to Tenant within fifteen
(15) days after such requirement is imposed. All rights and obligations under this Lease shall then cease. If Landlord does not receive 


11





 




condemnation proceeds sufficient for restoration (such as when its mortgagee does not allow the proceeds to be used for such purposes) and if restoration is economically reasonably feasible, Tenant
will have the option of supplementing available proceeds to allow restoration, and Tenant's actual costs will be reimbursed through a monthly prorata credit against rent beginning after Landlord's
mortgage has been paid in full. 


        18.    FIRE AND CASUALTY:    


        (a)  If
the Building should be damaged or destroyed by fire, tornado, or other casualty, Tenant shall give immediate verbal and written notice thereof to Landlord. 


        (b)  If
the Building should be totally destroyed by fire, tornado, or other casualty, or if it should be so damaged thereby that rebuilding or repairs cannot reasonably be
completed within one hundred eighty (180) days after the date on which Landlord is notified by Tenant of such damage, at the option of either Landlord or Tenant, this Lease shall terminate, and
the Rent shall be abated during the unexpired portion of this Lease effective upon the date of occurrence of such damage. 


        (c)  If
the Building should be damaged by any peril that will be wholly compensated (subject to deductibles) by the insurance maintained by Landlord or if Landlord, in its
sole discretion, so chooses notwithstanding a deficiency in such proceeds, and if rebuilding or repairs can reasonably be completed within one hundred eighty (180) days after the date on which
Landlord is notified by Tenant of such damage, this Lease shall not terminate, and Landlord shall then proceed with reasonable diligence to rebuild and repair the Building to substantially the same
condition in which it existed prior to such damage. Landlord shall not be required, however, to rebuild, repair, or replace Tenant's furniture, fixtures, Alterations, inventory or other personal
property. If the Leased Premises are untenantable in whole or in part during restoration, the Rent payable hereunder during the period in which they are untenantable shall be reduced by untenantable
portion in both Tenant and Landlords reasonable discretion. If Landlord should fall to complete such repairs and rebuilding within one hundred eighty (180) days after the date on which Landlord
is notified by Tenant of such damage, Tenant may terminate this Lease by delivering written notice of termination to Landlord. Such termination shall be Tenant's exclusive remedy and all rights and
obligations of the parties under the Lease shall then cease. Notwithstanding the foregoing provisions of this Paragraph 18(c), Tenant agrees that if the Leased Premises, the Building and/or
Project are damaged by fire or other casualty caused by the fault or negligence of Tenant or Tenant's Representatives, Tenant shall have no option to terminate this Lease even if the damage cannot be
repaired within one hundred eighty (180) days, and the Rent shall not be abated or reduced before or during the repair period. 


        (d)  Notwithstanding
anything herein to the contrary, if the holder of any indebtedness secured by a mortgage or deed of trust covering the Building and/or Project requires
that the insurance proceeds be applied to such indebtedness, then Landlord shall have the right to terminate this Lease by delivering written notice of termination to Tenant within fifteen
(15) days after such requirement is imposed. All rights and obligations under this Lease shall then cease. If Landlord does not receive insurance proceeds sufficient for restoration (such as
when its mortgagee does not allow the proceeds to be used for such purposes) and if restoration is economically reasonably feasible, Tenant will have the option of supplementing available proceeds to
allow restoration, and Tenant's actual costs will be reimbursed through a monthly prorata credit against rent beginning after Landlord's mortgage has been paid in full. 


12







  





        19.    CASUALTY INSURANCE:    Landlord shall at all times during the term of this Lease maintain a policy or
policies
of business or rental interruption insurance and a policy or policies of insurance insuring the Building against eighty percent (80%) of full replacement cost for loss or damage by fire, explosion,
and other customary hazards. Such policies will not insure any personal. property (including, but not limited to any furniture, machinery, goods, or supplies) of Tenant or which Tenant may have in the
Leased Premises or any fixtures installed by or paid for by Tenant upon or within the Leased Premises or any Alterations or other improvements which Tenant may construct or install on the Leased
Premises or any signs identifying Tenant's business located on the exterior of the Building, insurance for all of which shall be Tenant's responsibility. 


        20.    WAIVER OF SUBROGATION:    To the extent that Landlord or Tenant receives casualty insurance proceeds, such
recipient hereby waives and releases any and all rights, claims, demands and causes of action such recipient may have against the other on account of any loss or damage occasioned to such recipient or
its businesses, real and personal properties, the Leased Premises, the Building, the Project, or its contents, arising from any risk or peril covered by any insurance policy carried by either party
and for which such proceeds are actually received. Inasmuch as the above mutual waivers will preclude the assignment of any such claim by way of subrogation (or otherwise) to an insurance company (or
any other person), each party hereto agrees immediately to give to its respective insurance companies written notice of the terms of such mutual waivers and to have their respective insurance policies
properly endorsed, if necessary, to prevent the invalidation of such insurance coverages by reason of such waivers. This. provision shall be cumulative of Paragraph 21 below. 


        21.    HOLD HARMLESS:    Landlord shall not be liable to Tenant, Tenant's Representatives, or any other person for any
injury to person or damage to property on or about the Leased Premises or the Project caused by the negligence or misconduct of Tenant, Tenant's Representatives, or any other persons entering upon the
Leased Premises or the Project. Tenant agrees to indemnify and hold Landlord harmless from any and all loss, attorney's fees, expenses, or claims arising out of any such damage, loss or injury. Tenant
shall not be liable to Landlord, Landlord's employees, agents, invitees, licensees or visitors for any injury to person or damage to property on or about the Leased Premises or the Project caused by
the negligence or misconduct of Landlord, its agents, employees, agents, invitees, licensees or visitors. Landlord agrees to indemnify and hold Tenant harmless from any and all loss, attorney's fees,
expenses, or claims arising out of any such damage, loss or injury. 



        22.    QUIET ENJOYMENT:    Landlord warrants that it has full right to execute and to perform this Lease and to grant
the estate demised herein and that Tenant, upon payment of the required Rent and performance of the covenants and agreements contained in this Lease, shall peaceably and quietly have, hold, and enjoy
the Leased Premises during the full term of this Lease, including any extensions or renewals thereof. 


        23.    LANDLORD'S RIGHT OF ENTRY:    Landlord shall have the night to enter the Leased Premises for the following
reasons: inspection, cleaning or making repairs, making such alterations or additions as Landlord may deem necessary or desirable; installation of utility lines servicing the Leased Premises or any
other space in the Building, determining Tenant's use of the Leased Premises, or for determining if any event of default under this Lease has occurred. Landlord shall attempt to give
twenty-four (24) hours verbal notice to Tenant prior to such entry, except in cases of emergency or when an event of default has occurred in which cases Landlord may enter the
Leased Premises at any time and without prior notice. During the period that is six (6) months prior to the end of the Lease term, Landlord and Landlord's agents and representatives shall have
the right to enter the Leased Premises at any reasonable time during business hours, with reasonable notice, for the purpose of showing the Leased Premises and shall have the right to erect on the
Leased Premises a suitable sign indicating the Leased Premises are available for lease. 


13





 



        24.    ASSIGNMENT OF LANDLORD'S INTEREST IN LEASE:    Landlord shall have the right to transfer and assign, in whole
or in part, its rights and obligations with respect to the Project, the Leased Premises, and this Lease, including Tenant's Security Deposit. Upon and after such transfer, Landlord shall be released
from any further obligation under this Lease and Tenant agrees to look solely to Landlord's successor for the performance of such obligations. 


        25.    Intentionally Deleted    


        26.    DEFAULT BY TENANT:    The following shall be events of default by Tenant tinder this Lease: 



        (a)  Tenant's
failure to pay, within ten (10) days after it is due, any installment of Rent or other payment required pursuant to this Lease; 


        (b)  Tenant's
abandonment or vacation of any part of the Leased Premises, and Tenant is in default of the Rent payments due under this Lease; 


        (c)  Tenant's
failure to comply with any term, provision or covenant of this Lease, other than the defaults listed in the other subparagraphs of this Paragraph 26, and
the failure is not cured within ten (10) days after written notice thereof to Tenant; 



        (d)  Tenant's
filing of a petition or adjudication as a debtor or bankrupt insolvent under the Bankruptcy Code or any similar law or statute of the United States or any
state; or appointment of a receiver or trustee for all or substantially all of the assets of Tenant; or Tenant's transfer in fraud of creditors or assignment for the benefit of creditors of all or
substantially all of Tenant's assets;. 


        (e)  Tenant
doing or permitting to be done any act which results in a lien being filed against the Leased Premises and the same is not removed within sixty (90) days
after Landlord's notice thereof to Tenant. 




        27.    REMEDIES FOR TENANT'S DEFAULT:    Upon the occurrence of any event of default, Landlord shall have the option
to pursue any one or more of the following remedies without any prior notice or demand: 



        (a)  Landlord
may terminate this Lease, in which event Tenant shall immediately surrender the Leased Premises to Landlord, and if Tenant falls to do so, Landlord may, without
prejudice to any other remedy which it may have, enter upon and take possession of the Leased Premises, and expel or remove Tenant and any other person who may be occupying all or any part of the
Leased Premises. Landlord shall not be liable for prosecution or any claim for damages as a result of such actions. Tenant agrees to pay on demand the amount of all losses, costs, expenses,
deficiencies, and damages, including, without limitation, reasonable reconfiguration expenses, rental concessions and other inducements to new tenants, advertising expenses and broker's commissions,
which Landlord may incur or suffer by reason of Tenant's default or the termination of this Lease under this subparagraph, whether through inability to rent the Leased Premises on satisfactory terms
or otherwise. Tenant acknowledges that its obligation to pay Base Rent and all additional Rent hereunder is not only compensation for use of the Leased Premises but also compensation for sums already
expended and/or being expended by Landlord with respect to its obligations hereunder and with respect to the Leased Premises, and Tenant acknowledges that Tenant's default in timely payment of all
sums due hereunder shall constitute significant financial loss to Landlord. Tenant further acknowledges that any failure to pay any sum due hereunder shall evidence Tenant's inability to meet its
debts as they become due. In such event, in addition to Landlord's other remedies hereunder, Landlord shall be entitled to accelerate all Base Rental remaining unpaid hereunder, the entirety of which
shall at the option of Landlord be immediately due and payable to the extent allowed by law. 



14





 

        (b)  Without
termination of this Lease, Landlord may enter upon and take possession of the Leased Premises and expel or remove Tenant and any other person who may be
occupying all or any part of the Leased Premises (without being liable for prosecution or any claim for damages therefor) and relet the Leased Premises on behalf of Tenant and receive directly the
rent from the reletting. Tenant agrees to pay Landlord on demand any deficiency that may arise by reason of any reletting of the Leased Premises and to reimburse Landlord on demand for any losses,
costs, and expenses, including without limitation, reconfiguration expenses, rental concessions and other inducements to new tenants, advertising costs or broker's commissions, which Landlord may
incur or suffer as a result of Tenant's default or in reletting the Leased Premises. In the event Landlord is successful in reletting the Leased Premises at a rental in excess of that agreed to be
paid by Tenant pursuant to this Lease, Tenant agrees
that Tenant shall not be entitled, under any circumstances, to such excess rental, and Tenant does hereby specifically waive any claim to such excess rental. 


        (c)  Without
terminating this Lease, Landlord may enter upon the Leased Premises (without being liable for prosecution or any claim for damages therefor) and do whatever
Tenant is obligated to do under the terms of this Lease. Tenant agrees to reimburse Landlord on demand for any losses, costs and expenses which Landlord may incur in effecting compliance with Tenant's
obligations under this Lease. Tenant further agrees that Landlord shall not be liable for any damages resulting to Tenant from effecting compliance with Tenant's obligations under this subparagraph,
whether caused by the negligence of Landlord or otherwise. 


        (d)  With
respect to Landlord's entry upon the Leased Premises under the provisions of subparagraphs (a), (b), and (c) above, no restriction of, or obligation imposed
upon Landlord by, Texas Property Code Section 93.002 shall apply, such Section being superseded hereby. In particular, but without limitation, Landlord will have no duty or responsibility to
Tenant to tender a key in the event of a change of locks, and Tenant will have no further right of possession except as otherwise expressly agreed by Landlord in writing. 


        (e)  Landlord
may pursue any remedy provided at law or in equity. 


        (f)    Landlord
shall have no duty to relet the Premises, and the failure of Landlord to do so shall not release or affect Tenant's liability for Rent and other charges due
hereunder or for damages. 


        (g)  No
re-entry or reletting of the Premises or any filing or service of an unlawful detainer action or similar action shall be construed as an election by
Landlord to terminate this Lease unless a written notice of such intention is given by Landlord to Tenant. Notwithstanding any such reletting without termination, Landlord may at any time thereafter
elect to terminate this Lease and Tenant's right to possession hereunder. 


        (h)  Intentionally
Deleted. 




        28.    TERMINATION OF OPTIONS:    If there exist any options or special rights which Landlord may have granted Tenant
under this Lease including, but not limited to, options or rights regarding extensions of the term, expansion of the Leased Premises, or acquisition of any other interesting the Leased Premises, the
Building, or the Project, then all such options and rights independent of the leasehold estate hereby granted to Tenant by Landlord. Landlord and Tenant agree and acknowledge that the negotiated
consideration for any such options or special rights is Tenant's entry into this Lease and that no portion of any sums due and payable by Tenant to Landlord hereunder is attributable thereto. In
addition to, and not in lieu of, the above remedies of Landlord for Tenant's default, any and 


15





 


all such options or special rights shall be automatically terminated upon the occurrence of the following events: 



        (a)  Tenant
shall have failed to pay when due any installment of Rent or other sums payable under this Lease for any three (3) consecutive months during the Lease term
or any renewal or extension thereof, or for any ten (10) months during the Lease term or any renewal or extension thereof, whether or not said defaults are cured by Tenant; or 


        (b)  Tenant
shall have received two (2) or more notices of default under Paragraph 26(c) within any one calendar year with respect to any other covenant of this
Lease, whether or not such default(s) is/are cured; or 


        (c)  Tenant
shall have committed or suffered to exist any other event of default described under Paragraph 26 above, whether or not such default is cured by Tenant. 




        29.    WAIVER OF DEFAULT OR REMEDY:    Failure of Landlord to declare a default immediately upon its occurrence, or
delay in taking any action in connection with an event of default, shall not be a waiver of the default. Landlord shall have the right to declare the default at any time and take such action as its
lawful or authorized under this Lease. Pursuit of any one or more of the remedies set forth in Paragraphs 27 or 28 above shall not preclude pursuit of any one or more of the other remedies provided
therein or elsewhere in this Lease or as provided by law, nor shall pursuit of any remedy be a forfeiture or waiver of any Rent or damages accruing to Landlord by reason of the violation of any of the
terms of this Lease. Failure by Landlord to enforce one or more of its remedies upon an event of default shall not be construed as a waiver of the default or of any other violation or breach of any of
the terms contained in this Lease. 


        30.    CHOICE OF LAW; VENUE; ATTORNEY'S FEES:    It is specifically stipulated that this Lease shall be interpreted
and construed according to the laws of the State in which the Leased Premises are located, and any suit brought on this Lease shall be maintained in the county in which the Leased Premises are
located. Further, the prevailing party in any such litigation between the parties shall be entitled to recover, as a part of its judgment, reasonable attorney's fees and costs and expenses incurred
therein. 


        31.    HOLDING OVER:    Tenant will, at the termination of this Lease by lapse of time or otherwise, surrender
immediate possession to Landlord. If Landlord agrees in writing that Tenant may hold over after the expiration or termination of this Lease and if the parties do not otherwise agree, the hold over
tenancy shall be subject to termination by Landlord at any time upon not less than five (5) days advance written notice, or by Tenant at any time upon not less than thirty (30) days
advance written notice. Further, all of the terms and provisions of this Lease shall be applicable during the hold over period, except that Tenant shall pay Landlord from time to time upon demand, as
Base Rent for the
period of any hold over, an amount equal to 125% of the Base Rent in effect on the date of termination, computed on a daily basis for each day of the hold over period, plus all additional Rent and
other sums due hereunder. If Tenant shall fail immediately to surrender possession of the Leased Premises to Landlord upon termination of this Lease, by lapse of time or otherwise, and Landlord has
not agreed to such continued possession, as above provided, then, until Landlord can dispossess Tenant under the terms hereof or otherwise, Tenant shall pay Landlord from time to time upon demand, as
Base Rent for the period of any such hold over, an amount equal to twice the Base Rent in effect on the date of termination, computed on a daily basis for each day of the hold over period, plus all
additional Rent and other sums due hereunder. No holding over by Tenant, whether with or without consent of Landlord, shall operate to extend this Lease except as otherwise expressly agreed by the
parties. The preceding provisions of this Paragraph shall not be construed as Landlord's consent for Tenant to hold over. 


16





 



        32.    RIGHTS OF MORTGAGEE:    Tenant accepts this Lease subject and subordinate to any recorded mortgage, deed of
trust or other lien (a "Mortgage") presently existing or hereafter to exist with respect to the Leased Premises. Further, but without limiting the preceding sentence, Landlord is hereby irrevocably
vested with full power and authority to subordinate and/or to evidence such subordination of Tenant's interest under this Lease to any Mortgage hereafter placed on the Leased Premises, and Tenant
agrees upon demand to execute such additional instruments subordinating this Lease, and further defining the terms of such subordination, as well as the attornment discussed below, as Landlord or the
holder of any such Mortgage, may require. Tenant agrees to provide to the holder of any such Mortgage, whose name and address have been provided to Tenant (a "Mortgagee"), a copy of each notice to
Landlord which alleges any act, omission, or condition that might constitute a default by Landlord hereunder and Mortgagee, in its sole discretion, shall have all rights of Landlord hereunder to cure
any such default. If the interests of Landlord under this Lease shall be transferred by reason of foreclosure or other proceedings for enforcement of any Mortgage on the Leased Premises, at the
election of the transferee (sometimes called the "Purchaser") Tenant shall be bound to the Purchaser under the terms and conditions of this Lease for the balance of the remaining Lease term, including
any extensions or renewals, with the same force and effect as if the Purchaser were Landlord under this Lease; provided, however, that such Purchaser shall not be liable or bound to Tenant
(i) for any act or omission of any prior landlord, (ii) for any offsets or defenses which Tenant might have against any prior landlord, (iii) for or by any Rent which Tenant might
have paid for more than the current month, (iv) by any amendment modification of, or consensual termination agreement with respect to, the Lease made without the Mortgagee's consent,
(v) for any Security Deposit given by Tenant to a prior landlord unless such deposit is actually received by such Purchaser, (vi) for any repairs or replacements required by this Lease
arising prior to the date Purchaser takes possession of the Leased Premises, or (vii) for any moving, relocation or refurbishment allowance or any construction of or payment or allowance for
tenant improvements to the Leased Premises or any part thereof for the benefit of Tenant except as set forth in this Lease. Tenant further agrees at the election of the Purchaser to attorn to the
Purchaser, including the Mortgagee if it be the Purchaser, as its Landlord. Such attornment shall be effective without the execution of any further instruments upon the Purchaser's succeeding to the
interest of Landlord under this Lease. The respective rights and obligations of Tenant and the Purchaser upon the attornment, to the extent of the then remaining balance of the term of this Lease and
any extensions and renewals, shall be and are the same as those set forth in this Lease, but Tenant agrees upon demand to execute such additional instruments defining the terms of such attornment as
Landlord or the Purchaser may require. Each such Mortgagee and each such Purchaser shall be a third-party beneficiary of the provisions of this Paragraph. 



        33.    ESTOPPEL CERTIFICATES:    Tenant agrees to furnish on the Commencement Date of this Lease and from time to time
within ten (10) days of request by Landlord or Landlord's mortgagee, a statement certifying that the Tenant is in possession of the Leased Premises; the Leased Premises are acceptable; this
Lease is in full force and effect; this Lease is unmodified; Tenant claims no present charge, lien, or claim of offset against Rent; the Rent is paid for the current month but is not paid and will not
be paid for more than one month in advance (except estimated additional Rent under Paragraph 6); there is no existing default under this Lease; and such other matters as may be reasonably
required by Landlord or Landlord's mortgagee. 


        34.    SUCCESSORS:    This Lease shall be binding upon and inure to the benefit of Landlord and Tenant and their
respective heirs, personal representatives, successors and assigns. It is hereby covenanted and agreed that should Landlord's interest in the Leased Premises cease to exist for any reason during the
term of the Lease, then notwithstanding the happening of such even at the election of Landlord's successor herein, this Lease shall nevertheless remain unimpaired and in full force and effect and
Tenant hereunder agrees to attorn to the then owner of the Leased Premises. 


17





 



        35.    REAL ESTATE COMMISSION:    Tenant represents and warrants that is has dealt with no other broker, agent, or
other person other than Jackson & Cooksey in connection with this transaction, and that no other broker, agent, or other person brought about this transaction. Landlord and Tenant each agree to
indemnify and hold the other harmless from and against any claims by any broker, agent, or other person claiming a commission or other form of compensation by virtue of having dealt with Tenant or
Landlord respectively with regard to this transaction. The provisions of this Paragraph shall survive the termination of this Lease. 


        36.    DEFAULT BY LANDLORD:    Landlord shall not be in default, and Tenant shall have no right to any remedy at law
or in equity, unless the act, omission, or condition allegedly giving rise to such default shall have continued uncured or unabated for a period of thirty (30) days following written notice to
Landlord (with a copy to any Mortgagee as provided in Paragraph 32 above) or, if such cure or abatement cannot be accomplished within said 30-day period, then, so long as Landlord
or Mortgagee has commenced such cure or abatement within such 30-day period and diligently pursues same, such period shall be extended a reasonable time to allow completion of the cure or
abatement. 


        37.    MECHANIC'S LIENS:    Tenant shall have no authority, express or implied, to create or place any lien or
encumbrance of any kind or nature whatsoever upon, or in any manner to bind, the interest of Landlord in the Leased Premises or the Project or to charge the Rent payable hereunder for any claim in
favor of any person dealing with Tenant, including those who may furnish materials or perform labor for any construction or repairs. Each such claim shall affect, and each such lien shall attach to,
if at all, only the leasehold interest granted to Tenant by this Lease. Tenant covenants and agrees that it will pay or cause to be paid all sums legally due and payable by it on account of any labor
