forth in Section 1.7 of this Lease, which amount shall be payable to Landlord at
the address shown in section 1.9 above or at such other address that Landlord in
writing shall notify Tenant. The first monthly installment of rent due and
payable for March 15 - 31, 2001 (March rent to be pro rated for 1/2 month) and
April 1, 2001, shall be paid by Tenant at the time of execution of this Lease
Agreement, and a like monthly installment shall be due and payable on or before
the first day of each calendar month succeeding the Commencement Date during the

month, and all succeeding installments of rent shall be payable on or before the
first day of each succeeding calendar month during the term of this Lease.
Tenant shall pay the Excess Monthly Utility Charge as outlined in Article 1,

rentable square foot for the Property, in any calendar year during the term of
this Lease exceed the Operating Expense Base, Tenant agrees to pay as additional
rent Tenant's share of such excess operating expense. As used herein, the term
"Tenant's share of such excess Operating Expenses" means the amount by which
Landlord's Operating Expenses per net rentable square foot exceed the Operating
Expense Base, multiplied by the net rentable square feet comprising for each
calendar year, which amount shall be adjusted each year based upon anticipated
exceeded operating expenses. Within one-hundred twenty (120) days following the

in reasonable detail all computations of additional rent due under this Section.

exceeds the amount of additional rent due by Tenant under this Section, the
accounting shall be accompanied by a refund. If the accounting shows that the
total of the monthly payments made by Tenant is less than the amount of
additional rent due by Tenant under this Section, the accounting shall be
accompanied by an invoice for the additional rent. Notwithstanding any other
provisions in this Lease, during the year in which the Lease terminates,
Landlord, within one (1) year following the termination date, shall have the
option to invoice Tenant for Tenant's share of the excess operating expenses
based upon the previous year's operating expenses. If this Lease shall terminate
on a day other than the last day of a calendar year, the amount of any
additional rent payable by Tenant applicable to the year in which such
termination shall occur shall be prorated on the ratio that the number of days
from the commencement of the calendar to and including the termination date
bears to 365. Tenant shall have the right, at its own expense and within
reasonable time, to audit during Landlord's regular business hours Landlord's
books relevant to the additional rent payable under this Section.
Notwithstanding anything to the contrary contained in this Lease, if the
Building is not fully occupied during any calendar year, Tenant's additional
rent under this Section and the operating expenses shall be determined as if the
Building had been fully occupied during such year. Tenant agrees to pay any
additional rent due under this Section within thirty (30) days following receipt
of the invoice or accounting showing additional rent due, Calendar year 2001 to
be the base for calculation of pass through of operating expenses.

monthly excessive utility consumption charge shall be determined by multiplying
the electrical consumption calculated from the reading of the submeter(s) by the

any other window covering which would affect the exterior appearance of the
Building. Tenant may install lined or unlined over draperies on the interior
sides of the window coverings for interior appearance or to reduce light
transmission, provided such over draperies do not (in Landlord's determination)
affect the exterior appearance of the Building or affect the operation of the
Building's heating, ventilating and air conditioning systems.

necessary for the initial occupancy of the Leased Premises such construction
shall be accomplished and the cost of such construction shall be borne by
Landlord and/or Tenant in accordance with a separate Leasehold Improvements

interior nonstructural alterations to the Leased Premises. If, after its receipt
and review of any such notice, which notice shall specify in reasonable detail
the alterations to be made by Tenant, Landlord reasonably believes that the
interior non structural alteration in question will reduce the rental value of
the Leased Premises, then landlord, at its option, may within sixty (60) days
after its receipt of Tenant's written notice, deliver to Tenant a notice in
which Landlord designates the alteration in question as one that it may require
Tenant to remove at the end of the term of this Lease (each such alteration
being hereinafter referred to as "designated alteration"). Any alterations,
physical additions or improvements to the Leased Premises made by or installed
by either party hereto shall remain upon and be surrendered with the Leased

Such repairs to be replaced consistent with other space in the building.
Notwithstanding the preceding sentence to the contrary, any telecommunications
cable and conduit shall be removed at Tenant's discretion and at Tenant's sole
expense. This clause shall not apply to movable equipment, furniture, movable
trade fixtures owned by Tenant, which may be removed by Tenant at the end of the
term of this Lease if Tenant is not then in default and if such equipment and
furniture are not then subject to any other rights, liens and interests of

or cause any mechanic's or materialmen's lien, charge or encumbrance of any kind

limitation, legal fees and court costs).

                       ARTICLE 7 - CASUALTY AND INSURANCE


         7.1 Substantial Destruction. If in the determination of Landlord the
Leased Premises should be totally destroyed by fire or other casualty, or if in
the determination of Landlord the Leased Premises should be damaged so that
rebuilding cannot reasonably be completed substantially within one hundred and
eighty (180) working days after Landlord's receipt of written notification by
Tenant of the destruction, or if the Leased Premises are damaged or destroyed by
casualty not covered by the standard broad form of fire and extended coverage
insurance then in common use in the State of Texas, then, at either Party's
option, this Lease may be terminated and, in such event, the rent shall be
abated for the unexpired portion of the Lease, effective as of the date of the
written notification.

         7.2 Partial Destruction. If the following damage or destruction to the
Leased Premises by fire or other casualty, this Lease is not terminated pursuant
to section 7.1 hereof, Landlord shall proceed, to the extent of Insurance
proceeds actually received by Landlord after the exercise by any mortgagee of
the Property of an option to apply proceeds against Landlord's debt to such
mortgagee, with reasonable diligence to rebuild or repair the Building or other
improvements to substantially the same conditions in which they existed prior to
the damage. If the Leased Premises are to be rebuilt or repaired and are
untenantable in whole or in part following the damage, and the damage or
destruction was not caused or contributed to by act or negligence of Tenant, its
agents, employees, invitees or those for whom Tenant is responsible, the Base
Rent payable under this Lease during the period for which the Leased Premises
are untenantable shall be reduced to an amount determined by multiplying the
Base Rent that would otherwise by payable but for this provision by the ratio
that the portion of the Leased Premises not rendered untenantable bears to the
total net rentable area of the Leased Premises prior to the casualty. Landlord's
obligation to rebuild or restore under this Section shall be limited to
restoring the Leased Premises to substantially the condition in which the same
existed prior to the casualty, exclusive of improvements for which Tenant is
responsible under the terms of the Leasehold Improvements Agreement, if any,
described above in Section 6.1, and Tenant shall, promptly after the completion
of such work by Landlord, proceed with reasonable diligence and at Tenant's sole
cost and expense to restore those improvements for which Tenant is responsible
under the terms of such Leasehold Improvements Agreement to substantially the
condition in which the same existed prior to the casualty and to otherwise make
the Leased Premises suitable for Tenant's use. If Landlord fails to
substantially complete the necessary repairs or rebuilding within one hundred
and eighty (180) work days from the date of Landlord's receipt of written
notification by tenant of the destruction, Tenant may at its option terminate
this Lease by delivering written notice of termination to Landlord, whereupon
all rights and obligations under this Lease shall cease to exist.

         7.3 Property Insurance. Landlord shall at all times during the term
of this Lease insure the Property against all risk of direct physical loss in an
amount and with such deductibles as Landlord considers appropriate; provided,
Landlord shall not be obligated in any way or manner to insure any personal
property Including, but not limited to, any furniture, machinery, equipment,
goods or supplies) of Tenant upon or within the Leased Premises, any fixtures
installed or paid for by Tenant upon or within the Leased Premises, or any
improvements which Tenant may construction on the Leased Premises. Tenant shall
have no right in or claim to the proceeds of any policy of insurance maintained
by Landlord even if the cost of such insurance is borne by Tenant as set forth
in Article 2. Landlord shall have the right to self-insure against the
above-described risk. Tenant at all times during the term of this Lease shall,
at its own expense, keep in full force and effect insurance against fire and
other such risks as are from time to time included in standard all-risk
insurance (including coverage against vandalism and malicious mischief) for the
full insurable value of Tenant's merchandise, trade fixtures, furnishings, wall
coverings, carpeting, drapes, equipment, improvements and betterments,
furniture, supplies and all items of personal property of exempt located on or
within the Leased Premises.

         7.4 Waiver of Subrogation. Anything in this Lease to the contrary
notwithstanding, Tenant and its, underwriters hereby waive and release
Landlord's Representative from any and all right of recovery, claim, action or
cause of action, against Landlord and Landlord's Representative, their agents,
officers and employees, for any loss or damage that may occur to the Leased
Premises, improvements to the Property, or personal property within the
Property, by reason of fire or the elements, regardless of cause or origin,
including negligence of Landlord or Landlord's Representative and their agents,
officers and employees. Tenant agrees to immediately give its insurance
companies which have issued policies of insurance covering all risk of direct
physical loss, written notice of the terms of the waivers contained in this
Section, and to have the insurance policies properly endorsed, if necessary, to
prevent the invalidation of the insurance coverages by reason of the waivers.

         7.5 Hold Harm1ess. Landlord and Landlord's Representative shall not be
liable to Tenant or to Tenant's customers, employees, agents, guests or
invitees, or to any other person whomever, for any injury to persons or damage

Representative (including security service and devices), and Tenant hereby
agrees to indemnify Landlord and Landlord's Representative and hold Landlord and
Landlord's Representative harmless from any liability, loss, expense or claim
(including, but not limited to reasonable attorneys' fees) arising out of such
damage or injury. Nor shall Landlord or Landlord's Representative be liable to
Tenant for any loss or damage that may be occasioned by or through the acts or
omissions of other tenants of the Property or of any other persons whomsoever,
excepting only duly authorized employees and agents of Landlord and Landlord's
Representative acting within the scope of their authority. Further, Tenant
specifically agrees to be responsible for and Indemnify and hold Landlord and
Landlord's Representatives harmless from any and all damages or expenses of
whatever kind arising out of or caused by a burglary, theft, vandalism,
malicious mischief or other illegal acts performed in, at or from the Leased
Premises.

         7.6 Liability Insurance. Tenant at all times during the lease term
shall, at its own expense, keep in full force and effect commercial general

disposal, or transportation of any Hazardous Materials (as hereinafter defined)
on, under, in above, to or from the leased Premises other than in strict

regulations, and orders. For purposes of this provision, the term "Hazardous
Materials" shall mean and refer to any wastes, materials, or other substances of
any kind or character that are or become regulated as hazardous or toxic waste
or substances, or which require special handling or treatment, under any
applicable local, state, or federal law, rule regulation, or order. Tenant
shall indemnify, defend, and hold Landlord harmless from and against (a) any

required by, or incurred by Landlord or any other person or party in a a
reasonable belief that such Remedial Work is required by any applicable federal,

                            ARTICLE 8 - CONDEMNATION


         8.1 Substantial Taking. If in the determination of Landlord 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 purchase in lieu thereof, and in the determination of Landlord the
taking would prevent or materially interfere with the use of the Leased Premises
for the purpose for which it is then being used, this Lease shall, at the option
of either Landlord or Tenant, terminate and the rent shall be abated during the
unexpired portion of this Lease effective on the date physical possession is
taken by the condemning authority.

         8.2 Partial Taking. If in the determination of Landlord a portion of
the Leased Premises shall be taken for any public or quasi-public use under any
governmental law, ordinance or regulation, or by right of eminent domain or by
purchase in lieu thereof, and this Lease is not terminated as provided in
Section 8.1 above, Landlord shall restore and reconstruct, to the extent of
condemnation proceeds (excluding any proceeds or land) actually received after
the exercise by any mortgagee of the Property and other improvements on the
Leased Premises to the extent necessary to make it reasonably tenantable. The
rent payable under this Lease during the unexpired portion of the term shall be
reduced to an amount determined by multiplying the Base Rent that would
otherwise be payable but for this provision by the ratio that the portion of the
Leased Premises not rendered untenantable due to such taking bears to the total
net rentable area of the Leased Premises prior to the taking. If Landlord fails
to substantially complete such restoration and reconstruction within one-hundred
and eight working days of the date of physical possession by the condemning
authority, Tenant may at its option terminate this Lease by delivering written
notice of termination to Landlord, whereupon all rights and obligations of this
Lease shall cease to exist.

         8.3 Condemnation Proceeds. All compensation awarded for any taking (or
the proceeds of private sale in lieu thereof), whether for the whole or a part
of the Leased Premises, shall be the property of Landlord (whether such award is
compensation for damages to Landlord's or Tenant's interest in the Leased
Premises), and Tenant hereby assigns all of its interest in any such award to
Landlord; provided, however, Landlord shall have no interest in any award made
to Tenant for loss of business or for taking of Tenant's fixtures and other
property within the Leased Premises if a separate award for such items is made
to Tenant.

                      ARTICLE 9 - ASSIGNMENT OR SUBLEASE


         9.1 Tenant Assignment. Tenant shall not assign, in whole or in part,
this lease or allow it to be assigned, in whole or in part, or mortgagee or
pledge the same, or sublet the Leased Premises, in whole or in part without the
prior written consent of landlord which consent shall not be unreasonably
withheld or delayed. Assignment by operation of law, including merger,
dissolution of corporate tenant or transfer of controlling interest of corporate
tenant may be completed with written notice to the Landlord. In no event shall
any such assignment or sublease ever release Tenant or any guarantor from any
obligation or liability hereunder. No assignee or sublessee of the Leased
Premises or any portion thereof may assign or sublet the Leased Premises or any
portion thereof. Notwithstanding anything to the contrary contained in section
9.2, Tenant may assign or sublet all but not part of this Lease to any entity
controlled by, controlling or under common control with tenant without any need
to first obtain Landlord's consent; the term "control" being defined, for
purposes hereof, in the case of a corporation, as the ownership or voting
control, directly or indirectly, of at least fifty percent (50%) of all the
voting stock, and in case of a joint venture or partnership or similar entity,
ownership, directly or indirectly, of at least fifty percent of all the general
or other partnership (or similar) interest therein. Tenant agrees that written
assignment of Landlord fully obligates the assignee to all covenants and terms
of this entire lease.

         The parties agree that the decision by Tenant to enter into various
colocation and interconnection agreements with other entities in order to
connect its telecommunications facility to other telecommunications equipment
shall not be deemed an assignment or sublease of the Premises. As such, Tenant
may enter into such agreements without consent of Landlord, but Tenant agrees to
provide Landlord with notice after these agreements are completed, if so
requested by Landlord.

         9.2 Conditions of Tenant Assignment. If Tenant desires to assign or
sublet all or any part of the Leased Premises, it shall so notify Landlord in
writing at least thirty (30) days in advance of the date on which Tenant desires
to make such assignment or sublease. Tenant shall provide Landlord with a copy
of the proposed assignment or sublease and such information as Landlord might
request concerning the proposed sublessee or assignee to allow Landlord to make
informed judgments as to the financial condition, reputation, operations and
general desirability of the proposed sublessee or assignee. Within fifteen (15)
days after Landlord's receipt of Tenant's proposed assignment or sublease and
all required information concerning the proposed sublessee or assignee, Landlord
shall have the following options: (1) cancel this Lease as to the Leased
Premises or portion thereof proposed to be assigned or sublet; (2) consent to
the proposed assignment or sublease, and if the rent due and payable by any
assignee or sublessee under any such permitted assignment or sublease (or a
combination of the rent payable under such assignment or sublease plus any bonus
or any other consideration or payment incident thereto) exceeds the rent payable
under this Lease for such space, Tenant shall pay to Landlord all such excess
rent and other excess consideration within ten (10) days following receipt
thereof by Tenant; or (3) refuse in its reasonable discretion and judgment to
consent to the proposed assignment; or sublease which refusal shall be deemed to
have been exercised unless Landlord gives Tenant

written notice stating otherwise. Upon the occurrence of an event of default by
Tenant under this lease, if all or any part of the Leased Premises are then
assigned or sublet, Landlord in addition to any other remedies provided by this
lease or provided by law, may, at its option, collect directly from the assignee
or sublessee all rents becoming due to Tenant by reason of the assignment or
sublease, and Landlord shall have a security interest in all properties
belonging to Tenant on the Leased Premises to secure payment of such sums. No
collection directly by Landlord from the assignee or sublessee shall be
construed to constitute a novation or a release of Tenant or any guarantor from
the further performance of its obligations under this Lease. All reasonable
legal fees and expenses incurred by Landlord in connection with the review by
Landlord of Tenant's requested assignment or sublease pursuant to this Section,
together with any legal fees and disbursements incurred in the preparation
and/or review of any documentation, shall be the responsibility of Tenant and
shall be paid by Tenant within five (5) days of demand for payment thereof, as
rental hereunder. If the rent due and payable by any assignee or sublessee under
any such permitted assignment or sublease (or a combination of the rent payable
under such assignment or sublease plus any bonus or any other consideration or
any payment incident thereto) exceeds the rent payable under this lease for such
space, Tenant shall pay to Landlord all such excess rent and other excess
consideration within ten (10) days following receipt thereof by Tenant.

         9.3 Landlord Assignment. Landlord shall have the right to sell,
transfer or assign, in whole or in part, its rights and obligations under this
Lease and in the Property. Any such sale, transfer or assignment shall operate
to release Landlord from any and all liabilities under this lease arising after
the date of such sale, assignment or transfer.

         9.4 Rights of Mortgagee. Tenant accepts this Lease subject and
subordinate to any recorded Lease, mortgage or deed of trust lien presently
existing, if any, or hereafter encumbering the Property and to all existing
ordinances and recorded restrictions, covenants, easements, and agreements with
respect to the Property. Landlord hereby is irrevocably vested with full power
and authority to subordinate Tenants interest under this lease to any mortgage
or deed of trust lien hereafter placed on the Property. Upon any foreclosure,
judicially or non-judicially, of any such mortgage, or the sale of the Property
in lieu of foreclosure, or any other transfer of Landlord's interest in the
Property, whether or not in connection with a mortgage, Tenant hereby does, and
hereafter agrees to attorn to the purchaser at such foreclosure sale or to the
grantee under any deed in lieu of foreclosure or to any other transfer of
Landlord's interest, and shall recognize such purchaser, grantee, or other
transferee as Landlord under this Lease, end no further attornment or other
agreement shall be required to effect evidence Tenant's attornment to and
recognition of such purchaser or grantee as Landlord hereunder. Such agreement

conveyance in lieu thereof, or any other transfer of Landlord's interest in the

any time, before or after any such foreclosure sale, trustee's sale, conveyance

any remedy Tenant might possess as result of such default; and such other
matters as may be reasonably required by Landlord or Landlord's mortgagee.
Tenant's failure to deliver such statement, in addition to being a default under

force and effect except as declared by Landlord, that Landlord is not in default
of any af its obligations under this Lease, and that Landlord has not received

one or more of the remedies set forth in this Section 11.2 without any

and take possession of the Leased Premises, by picking or changing locks if
necessary, and lock out, expel or remove Tenant and any other person who may be
occupying all or any part of the Leased Premises without being liable for any

obligations under this Lease caused by the negligence of Landlord or otherwise.

         (3) Landlord may terminate this Lease, in which event Tenant shall

Premises on satisfactory terms or otherwise.

company from who a new key may be obtained, nor shall Landlord have any duty to
provide Tenant with a new key or any other means of access to the Leased
Premises. Landlord and Tenant agree that the parties hereto intend that all
rights and remedies of Landlord under this Lease or otherwise available to

otherwise defaults at any time during the term of this Lease, the rent
concessions, including any waived base rent, shall be canceled and the amount of
the base rent or other rent concessions shall be due and payable immediately as
if no rent concessions or waiver of any base rent had ever been granted. A rent
concession or waiver of the base rent shall not relieve Tenant of any obligation
to pay any other charge due and payable under this Lease or otherwise available
to Landlord under applicable law shall supercede any conflicting provisions of
Chapters 92 and 93 of the Texas Property code, and any amendments,
modifications, recodification or other changes thereto.

Notwithstanding any other remedy set forth in this Lease, if Landlord has made
rent concessions of any type or character, or waived any base rent, and Tenant
fails to take possession of the leased Premises on the Commencement Date or
otherwise defaults at any time during the term of this Lease, the rent
concessions, including any waived base rent, shall be canceled and the amount of
the base rent or other rent concessions shall be due and payable immediately as
if no rent concessions or waiver of any base rent had ever been granted. A rent
concession or waiver of the base rent shall not relieve Tenant of any obligation
to pay any other charge due and payable under this Lease, including, without
limitation, any sum due under Section 2.3 of this Lease. Notwithstanding
anything contained in this Lease to the contrary, this lease may be terminated
by Landlord only by written notice of such termination to Tenant given in
accordance with Section 14.7 below, and no other act or omission of Landlord
shall be construed as a termination of this Lease.

         10.3 Remedies Cumulative. All rights and remedies of Landlord
herein or existing at law or in equity are cumulative and the exercise of one or
more rights or remedies shall not be taken to exclude or waive the right to the
exercise of any other.

         10.4 Defau1t by Landlord. If Landlord defaults in the performance of
any term, covenant or condition required to be performed by Landlord under this
Lease, Landlord shall have thirty (30) days following the receipt of written
notice from Tenant specifying such default to cure such default, provided that
if Landlord has commenced actions to cure such default within said thirty (30)
day period, Landlord shall have all reasonable and necessary time to complete
such cure

         10.5 Remedies for Landlords Default. Upon the occurrence of any
default set forth in this Lease and subsequent failure by Landlord to cure or
commence actions to cure as provided in Section 10.4, Tenant shall, as Tenant's
sole remedy, have the right to maintain an action against Landlord, for actual
damages suffered as a result of Landlord's default.

         10.6 Notice to Mortgagees. Provided that Tenant has received prior
written notice of the name and address of such lender, Tenant shall serve
written notice of any claimed default or breach by landlord under this Lease
upon any lender which is a beneficiary under any deed of trust or mortgage
against the Leased Premises, and no notice to Landlord shall be effective
against Landlord unless such notice is served upon said lender; notwithstanding
anything to the contrary contained herein, Tenant shall allow such lender the
same period following lender's receipt of such notice to cure such default or
breach as is afforded Landlord.


                            ARTICLE 11 - DEFINITIONS


         11.1 Abandon. "Abandon" means the vacating of all or a substantial
portion of the leased Premises by Tenant, and Tenant is in default of the rental
or other payments due under this Lease.

         11.2 Act of God or Force Majeure. An "act of God" or "force majeure" is
defined for purposes of this Lease as strikes, lockouts, sitdowns, material or

Landlord is unable wholly or in part, to prevent or overcome.

                           ARTICLE 13 - MISCELLANEOUS


         13.1 Waiver. Failure of Landlord to declare an event of default
immediately upon its occurrence, or delay in taking any action in connection
with an event of default, shall not constitute a waiver of the default, but
Landlord shall have the right to declare the default at any time and take such
action as is lawful or authorized under this Lease. Pursuit of any one or more
of the remedies set forth in Article 11 above shall not preclude pursuit of
anyone or more of the other remedies provided elsewhere in this Lease or
provided by law, nor shall pursuit of any remedy hereunder or at law constitute
forfeiture or waiver of any rent or damages accruing to Landlord by reason of
the violation of any of the terms, provisions or covenants of this Lease.
Failure by Landlord to enforce one or more of the remedies provided hereunder or
at law upon any event of default shall not be deemed or construed to constitute
a wavier of the default or of any other violation or breach of any of the terms,
provisions and covenants contained in this lease. Landlord may collect and
receive rent due from Tenant without waiving or affecting any rights or remedies
that Landlord may have at law or in equity or by virtue of this lease at the
time of such payment. Institution of a forcible detainer action to re-enter the
Leased Premises shall not be construed to be an election by Landlord to
terminate this Lease.


         13.2 Act of God. Landlord shall not be required to perform any
covenant or obligation in this Lease, or be liable in damages to Tenant, so long
as the performance or non-performance of the covenant or obligation is delayed,
caused or prevented by an act of God, force majeure or by Tenant.

         13.3 Attorneys Fees. If Tenant defaults in the performance of any of
the terms, covenants, agreements or conditions contained in this lease and
Landlord places in the hands of any attorney the enforcement of all or any part
of this lease, the collection of any rent or other sums due or to become due or
recovery of the possession of the Leased Premises, Tenant agrees to pay
Landlord's costs of collection, including reasonable attorney's fees, whether
suit is actually filed or not.

         13.4 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.

the Lease apply (1) in the plural sense where there is more than one tenant, and
(2) to either corporations, associations, partnerships or individuals, males or
females, shall in all instances be assumed as though in each case fully
expressed. The laws of the State of Texas shall govern the validity, performance
and enforcement of this Lease. This Lease shall not be construed more or less
favorably with respect to either party as a consequence of this lease or various
provisions hereof having been drafted by one of the parties hereto.

         13.7 Notices. All rent and other payments required to be made by
Tenant shall be payable to Landlord, in care of Manager, at Manager's address
set forth on page 1 (or if no address be set forth for Manager, to Landlord at

Landlord to Tenant shall be payable to Tenant at Tenant's address set forth on

to Landlord's address as shown on page 1. Manager shall be a co-addressee with
Landlord on all notices sent to Landlord by Tenant hereunder, and any notice
sent to Landlord and to Manager, also in accordance with this section shall be
deemed effective upon receipt and is acceptable to use a reputable courier
service.

         13.8 Submission of Lease. Submission of this Lease to Tenant for
signature shall not constitute a reservation of space or an option to Lease.
This Lease is not effective until execution by and delivery to both Landlord and
Tenant.

         13.9 Corporate Authority. If Tenant executes this Lease as a
corporation or a partnership (general or limited), each person executing this

is a duly authorized and existing corporation or partnership (general or
limited), Tenant is qualified to do business in the state in which the Leased
Premises are located, the corporation or partnership (general or limited) has
full right and authority to enter into this Lease, each person signing on behalf
of this Lease by Tenant will not result in any breach of, or constitute a
default under any mortgage, deed of trust, lease, loan credit agreement,
partnership agreement, or other contract or instrument to which Tenant is a
party or by which tenant may be bound. If any representation or warranty
contained in this Section is false, each person who executes this Lease shall be
liable, individually, as Tenant hereunder.

         13.10 Multiple Tenants. If this Lease is executed by more than one
person or entity as "Tenant," each such person or entity shall be jointly and
severally liable hereunder. It is expressly understood that anyone of the named
Tenants shall be empowered to execute any modification, amendment, exhibit,
floor plan, or other document herein referred to and bind all of the named
Tenants thereto; and Landlord shall be entitled to rely on same to the extent as
if all of the named tenants had executed same.

         13.11 Tenants Financial Statements. Tenant represents and warrants to
Landlord that, as of the date of execution of this Lease by Tenant, the
financial statements of Tenant provided to Landlord prior to or simultaneously
with the execution of this Lease accurately represent the financial condition of
Tenant as of the dates and for the periods indicated therein, such financial
statements are true and do not contain any untrue statement of a meterial fact
or omit to state any material fact necessary in order to make the statements
included therein not misleading and there has been no material adverse change in
the financial condition or business prospects of Tenant since the respective
dates of such financial statements. If there is, in Tenant's reasonable
judgment, a material adverse change in Tenants financial condition, Tenant will
give immediate notice of such material adverse change to Landlord. If Tenant
fails to give such immediate notice to Landlord, such failure shall be deemed an
event of default under this Lease.

         13.12 Severability. If any provision of this lease or the application
thereof to any person or circumstances shall be invalid or unenforceable to any
extent, the remainder of this Lease and the application of such provisions to
other persons or circumstances shall not be affected thereby and shall be
enforced to the greatest extent permitted by law. Each covenant and agreement
contained in this Lease shall be construed to be a separate and independent
covenant and agreement, and the breach of any such covenant or agreement by
Landlord shall not discharge or relieve Tenant from Tenant's obligation to
perform each and every covenant and agreement of this Lease to be performed by
Tenant.

         13.13 Landlord's Liability. If Landlord shall be in default under this
