     Re:  GlobalSCAPE, Inc. 1998 Stock Option Plan (the "Stock Option Plan")

Dear [Officer]:

     On January 1, 1998 you and GlobalSCAPE, Inc. ("GlobalSCAPE") signed a
letter under which GlobalSCAPE granted you an option vesting over a three year
period beginning January 1, 1998 (the "Option").

     Section 9 of the letter and Section 5 of the Plan contain provisions
requiring adjustment of your Option under circumstances described in those
provisions. As you know, the Boards of Directors of GlobalSCAPE and ATSI have
approved a financing plan as described in more detail on the attached Exhibit A
                                                                      ---------
(the "Financing Plan"). To create the number of common shares needed to
establish a viable public market as contemplated by this plan, GlobalSCAPE will
either have to issue substantially more shares than the 1.7 million currently
outstanding, or will have to declare a stock split. The issuance of additional
shares or a stock split, taken by itself, might give rise to a requirement that
the number of shares subject to your Option be adjusted. However, we believe
that any new issuance or stock split that occurs would be part of the financing
Plan described on Exhibit A which, as a whole, is not the type of event that
                  ---------
should give rise to an adjustment under the letter and the Plan. In exchange for
$5,000, you have agreed that you will not claim any right of adjustment in the
number of common shares underlying your Option under the terms of the letter and
the Plan as a result of the consummation of the Financing Plan, and you agree
that you will not claim that the financing plan was unfair to you.

     Please sign this letter where indicated below and return it to me to
acknowledge your agreement.

     Re:  GlobalSCAPE, Inc. 1998 Stock Option Plan

Dear [Officer]:

     On January 1, 1998 you and GlobalSCAPE, Inc. ("GlobalSCAPE") signed a
letter under which GlobalSCAPE granted you an option to purchase 291,429 shares
of GlobalSCAPE common stock for $0.10 (ten cents) per share with the option
vesting over three year period beginning January 1, 1998.

     As you know, GlobalSCAPE would like to offer shares of its common stock to
the public to raise money to finance its future growth. If completed, this
transaction will benefit you since it will create a market for your GlobalSCAPE
shares when you exercise your Option.

     We have to plan and budget carefully in order to complete all the steps
necessary to close the offering, and the steps we take depend on whether there
are any shareholders of GlobalSCAPE other than ATSI. If you were to exercise any
part of your Option during time leading up to the offering it would be difficult
for us to revise our plans and still close the offering within the time frame
that we believe is desirable. Therefore, to facilitate this offering,
GlobalSCAPE would like you to agree that you will not exercise your Option until
the offering is complete. We cannot guaranty [sic] that the offering will be
complete by a certain date, but we anticipate that it will be complete by August
31, 2000.

     If you agree not to exercise your option as described in this letter,
please sign below where indicated and return a signed copy of this letter to me.
If we have not completed the offering by August 31, 2000, or if we decide not to
proceed with the offering prior to that time, then you will be free to exercise
your option. Also, if your employment is terminated four months or more prior to
the completion of the offering, and you and the Board of Directors of
GlobalSCAPE have not agreed to extend the time that you have to exercise your
Option, then you will be free to exercise your option on the last day of the
four month period following the termination of your employment.

                                      Sincerely,

                                      Arthur L. Smith

    1.07 Leasing Term Limitation on Adjacent Space and Right of First Refusal.
Lessor agrees that Lessee may lease the Bay shown on Exhibit "A" adjacent to the
Leased Premises at any time prior to Lessor leasing the Bay to another person.
Lessor agrees that it will notify Lessee at least thirty (30) days prior to
entering into a lease of the Bay, and will not enter into a lease for the Bay
for a term that continues longer than sixty (60) months. Lessor further agrees
that it will notify Lessee ninety (90) days prior to the expiration of any lease
of the Bay (or immediately upon learning that the Bay is to become available
prior to the expiration of its lease) and Lessee will have fifteen (15) days
following receipt of notice to notify Lessor that it elects to lease the Bay. If
Lessee does not notify Lessor that it elects to lease the Bay within fifteen
(15) days, Lessor may re-let the Bay for a term of up to sixty (60) Months. If
Lessee elects to lease the Bay pursuant to this Section, then Lessor and Lessee
will execute a modification of this Lease such that the Bay becomes part of the
Leased Premises and is leased on the same terms and conditions as provided in
this Lease for the initial Leased Premises, including renewal options, but not
including the rental per square foot, finish out allowance, and refurbishment
allowance, with an additional security deposit to be calculated in the same
manner as the security deposit for the Leased Premises, and with the term of the
lease for the Bay to expire on the Termination Date. If Lessee elects to lease
the Bay prior to the time that Lessor completes the Lessee Improvements, then
the Bay will be leased on all of the same terms and

Commercial Lease - Page 2 of 44

<PAGE>

conditions as the initial Leased Premises, including rental per square foot.
renewal options. finish out allowance, and refurbishment allowance. The date for
completion of Lessee Improvements in the Bay will be established consistently
with the time frames for completion of Lessee Improvements for the initial
Leased Premises.

    1.08 Lessee's Future Expansion Needs. Lessor acknowledges that Lessee
expects its business to grow significantly and that Lessee may require space in
addition to the Leased Premises and the Bay. Lessor will keep Lessee informed of
the status of the remaining space in the Building and give Lessee a reasonable
opportunity to lease additional space that becomes available on reasonable terms
and conditions.

    1.09 Renewal Terms. Lessor agrees that Lessee may renew the Lease for two
successive sixty (60) month renewal terms (each a "Renewal Term") by giving
Lessor written notice of renewal at least one hundred eighty (180) days prior to
the expiration of the Term or the first Renewal Term, respectively The Lease
will continue on the same terms and conditions during any Renewal Term, except
that the rental rate per square foot shall be adjusted to ninety five percent
(95%) of the prevailing market rate for comparable buildings in San Antonio at
the time of renewal (taking into consideration the age and quality of the
structure, type of building, location of the space in the building, definition
of the leased area, estimated lease-up time, credit standing and financial
status of the Lessee, term, extent of services provided by landlord, brokerage
fees, leasehold improvement allowances, moving allowances, rental abatements and
other incentive being offered). If there is a difference in opinion between
Lessor and Lessee regarding the prevailing market rate of rental at the time of
Renewal, Lessor and Lessee will negotiate in good faith to resolve the
difference. Lessor and Lessee will also negotiate in good faith to establish a
refurbishment allowance for the Leased Premises, which shall be administered by
Lessor on the same terms and conditions as the Improvement Allowance for the
Initial Lessee Improvements. Lessee may withdraw its notice of renewal if
agreement on the prevailing market rate of rental is not reached within sixty
(60) days of the beginning of the proposed Renewal Term.

    1.10 Contingencies. Lessor agrees that if by May 1, 1999, Lessor has failed
to acquire title to the land on which the Building is to be constructed. or if
by June 1, 1999 it has not commenced construction of the Building. Lessee may
terminate this Lease on one (1) day's advance written notice. Lessor agrees that
Lessee's security deposit and is due upon execution of the Lease; however Lessor
and Lessee further agree that such payment will not be deposited until such time
as Lessor has acquired title to the land on which the Building is to be
constructed, and seventh month's rent is due upon Lessor's commencement of
Lessee improvements.

    1.11 Must Take Space. Lessee will notify Lessor at least three (3) calendar
months prior to the date that Lessee desires to lease the Must Take Space and
will provide Lessor with its preliminary plans and specifications for Lessee
Improvements to the Must Take Space within forty-five (45) days of the date that
it desires to take possession of the Must Take Space. The date for completion of

the time frames for completion of Lessee Improvements for the Initial Space.

                              ARTICLE 2.00 - RENT

    2.01 Base Rent. Lessee agrees to pay monthly as base rent during the term of
this Lease without notice, demand, counter-claim, set-off or abatement, except
as otherwise set forth herein, the sum of money set forth in Section 1.04 of
this Lease, which amount is payable to Lessor at the address shown above, except
that Lessee shall not pay any base rent for the first six full calendar months
following the Commencement Date. One monthly installment of rent is due and
payable on the date of execution of this Lease by Lessee for the seventh month's
rent and a like monthly installment is due and payable on or before the first
day of each succeeding calendar month during the term of this Lease; provided,
if the Commencement Date should be a date other than the first day of a calendar
month, the free rental period set forth above will begin on the Commencement
Date and the rental for the remainder of the calendar month in which the free
rental period ends will be prorated and will be due on the first day of the
calendar month first following the end of the free rental period. Lessee shall
pay, as additional rent, all other sums due under this Lease. If Lessee elects
to lease the Must Take Space and the lease of the Must Take Space begins prior
to the end of the free rental period (or would have begun during the free rental
period except for Lessor Delay), Lessee will not be obligated to pay rent on the
Must Take Space for the remainder of the free rental period.

    2.02 Additional Rent. Lessee agrees to pay as additional rent, without
deduction or set-off of any kind except as otherwise set forth herein, Lessee's
pro rata share of all ad valorem taxes and installments of special assessments
(including dues and assessments by means of deed restrictions and/or owner's
associations) lawfully levied or assessed against the Building (as hereinafter
defined) of which the Leased Premises are a part and any and all insurance
required herein or which is standard for similar projects (specifically
including fire and casualty, commercial general liability and rent loss
insurance). Said ad valorem taxes, assessments and insurance shall be prorated
and paid on or before the first day of every month commencing on the
Commencement Date, in advance, as additional rent. The proration shall be based
upon Lessor's estimate of ad valorem taxes, assessments and insurance for the
current calendar year, provided, that in the event Lessor is required under a
mortgage, deed of trust, underlying lease or loan agreement covering the
Building to escrow ad valorem taxes, assessments or insurance, Lessor may but
shall not be obligated, to use the amount required to be escrowed as a basis for
its estimate. There will be an annual accounting as to actual ad valorem taxes,
assessments and insurance and appropriate payment or credits made. To the extent
the Commencement Date or Termination Date of the Lease is not on the first day
of the calendar year or last day of the calendar year respectively, Lessee's
liability for ad valorem taxes, assessments and insurance shall be subject to a
pro rata adjustment based on the number of days of any such year during which
the Term is in effect. Lessee shall have the right at its expense to contest or
appeal by appropriate proceedings any value assessment rendered by applicable
taxing authorities and Lessor shall cooperate to the extent reasonably necessary
in such contest or appeal. To the extent the Leased Premises are part of a
multi-occupancy building, Lessee shall pay a pro rata share of such ad valorem
taxes, assessments and insurance, such pro rata share to be equal to the product
obtained by multiplying the total of such real property taxes assessments and
insurance by a fraction, the numerator of which shall be the number of square
feet of floor area of the Leased Premises and the denominator of which shall be
the number of square feet of floor area in the Building of which the Leased
Premises are a part.

Commercial Lease - Page 4 of 44

<PAGE>

    2.03 Operating Expenses. Lessee agrees to pay, as additional rent, Lessee's
pro rata share (as determined by the formula set forth in Section 2.02 above) of
Lessor's Operating Expenses for the Building without deduction or set-off of any
kind except as otherwise set forth herein. Lessor may invoice Lessee monthly for
Lessee's pro rata share of the estimated Operating Expenses for each calendar
year, which amount shall be adjusted from time-to-time based upon anticipated
Operating Expenses. As of the date hereof, it is estimated that the Operating
Expenses, taxes and insurance for calendar year 2000 will be approximately $2.20
per rentable square foot. Lessor agrees that the Lessee's portion of the
Operating Expenses for common area maintenance, less costs of utilities, costs
required to meet applicable laws, and capitalized costs of capital improvements
and operating efficiency devices, will not exceed seventy-eight cents ($78) per
rentable square foot during the first year of the Term (the "Base Amount"), and
will not increase for any year by more than five percent (5%) per year
(cumulative) over the Base Amount. Within four months following the close of
each calendar year, Lessor shall provide Lessee an accounting showing in
reasonable detail all computations of additional rent due under this Section. In
the event the accounting shows that the total of the monthly payments made by
Lessee exceeds the amount of additional rent due by Lessee under this Section,
such amount shall be credited against the next required payment of base rent. In
the event the accounting shows that the total of the monthly payments made by
Lessee is less than the amount of additional rent due by Lessee under this
Section, the account shall be accompanied by an invoice for the additional rent.
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 Lessee 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 year to and including the
termination date bears to 365. Provided Lessee is not in default of any terms of
this Lease, Lessee shall have the right, at its own expense, to audit Lessor's
books relevant to the additional rent payable under this Section. With respect
to such audit, Lessee 1) may review Lessor's books during office hours, 2) must
perform such audit at the location of Lessor's books, 3) must request such audit
within six (6) months of receipt of its annual reconciliation of Operating
Expenses, 4) must deliver to Lessor a copy of the results of such audit, 5) may
not audit the same calendar year more than one time. If, as a result of such
audit, it is determined that the Operating Expenses have been overstated by 3%
or more, Lessor shall be required to reimburse Lessee for the costs of such
audit. Assignees of Lessee may only audit periods for which they occupy the
Leased Premises and subtenants of Lessee shall have no audit rights. Lessee
agrees to pay any additional rent due under this Section within ten (10) days
following receipt of the invoice or accounting showing additional rent due.

    2.04 Definition of Operating Expenses. The term "Operating Expenses"
includes all expenses incurred by Lessor with respect to the maintenance and
operation of the Building (except for items described below) and includes, but
is not limited to, the following: maintenance, repair and replacement costs;
security; wages and benefits payable to employees of Lessor to the extent their
duties are directly connected with the operation and maintenance of the
Building; management fees, all services, utilities for common areas, supplies,
repairs, replacement or other expenses for maintaining and operating the common

expense required to be capitalized under GAAP principles other than capital
improvements; the cost, amortized over its useful life, of any capital

required

Commercial Lease - Page 5 of 44

<PAGE>

under any governmental law or regulation other than improvements made to the
Building to effect compliance with the Americans With Disabilities Act (the
"ADA") or as otherwise set forth herein, which capital improvements must be of
mutual benefit to all tenants of the Building; and the cost, amortized over its
useful life, of installation of any device or other equipment to the extent it
improves the operating efficiency of any system within the Leased Premises and
thereby reduces Operating Expenses, provided that, prior to installing any such
device or equipment, Lessor will inform Lessee of such installation and the
estimated cost savings and Lessor and Lessee must reasonably agree upon the
estimated cost savings before agreeing to such installation. The term Operating
Expenses does not include the following: expenses incurred to maintain the roof,
foundation and structural soundness of the exterior walls of the Building;
expenses incurred should the entire roof the Building need to be replaced;
expenses to bring the Building into compliance with applicable law such as the
ADA and Environmental Laws, expenses incurred to abate or remove any Hazardous
Substance in the Building that was placed there by Lessor, income and franchise
taxes of Lessor; expenses incurred in leasing to or procuring of lessees,
leasing commissions, advertising expenses and expenses for the renovating of
space for new lessees; interest or principal payments on any mortgage or other
indebtedness of lessor; compensation paid to any employee of Lessor other than
maintenance and property management personnel to the extent these services are
directly associated with the operation and maintenance of the Building; any
depreciation allowance or expense (except for depreciation of capital
improvements and equipment specifically included within the definition of
Operating Expenses); or operating expenses which are the responsibility of
Lessee or any other lessee of the Building; or expenses (herein called "Defect
Expenses") incurred as a result of or caused by latent defects, punch list
items, or Lessor's failure to construct the Shell Building Improvements or

substantially in accordance with the Final Shell Plans and Specifications and
Lessee Improvements Final Plans and Specifications as provided herein (such
items being herein called "Defects"); and/or operating expenses otherwise caused
by or resulting from Lessor's breach of its obligations under the Lease.

    2.05 Late Payment Charge. Other remedies for nonpayment of rent
notwithstanding, if the monthly rental payment is not received by Lessor on or
before the fifth day of the month for which the rent is due, or if any other
payment due Lessor by Lessee is not received by Lessor on or before the fifth
day of the month next following the month in which Lessee was invoiced, Lessee
agrees to pay a late payment charge of five percent (5%) of such past due amount
in addition to such amounts owed under this Lease, provided, however, that
Lessee is hereby granted a waiver of this late payment charge once every twelve
(12) months during the term of this Lease. In addition, Lessor is entitled to
charge one-hundred dollars ($100.00) for each check or payment which is not
honored by Lessee's bank. Said charge is in addition to any other amounts owed
under this Lease.

    2.06 Security Deposit. The security deposit set forth above will be held by
Lessor for the performance of Lessee's covenants and obligations under this
Lease, it being expressly understood that the deposit is not an advance payment
of rental or a measure of Lessor's damage in case of default by Lessee. Upon the
occurrence of any event of default by Lessee or breach by Lessee of Lessee's
covenants under this Lease, Lessor may, from time to time, without prejudice to
any other remedy, use the security deposit to the extent necessary to make good
any arrears of

Commercial Lease - Page 6 of 44

<PAGE>

rent, or to repair any damage or injury, or pay any expense or liability
incurred by Lessor as a result of the event of default or breach of covenant,
and any remaining balance of the security deposit will be returned by Lessor to
Lessee within a reasonable period of time following termination of this Lease.
If any portion of the security deposit is so used or applied, Lessee shall upon
ten days written notice from Lessor, deposit with Lessor by cash or cashier's
check an amount sufficient to restore the security deposit to its original
amount.

    2.07 Holding Over. In no event may Lessee remain in the Leased Premises
following the expiration or termination of this Lease without Lessor's prior
written consent. If Lessee does not vacate the Leased Premises upon the
expiration or termination of this Lease, Lessee agrees that it will be a tenant
at will for the holdover period and that all of the terms and provisions of this
Lease are applicable during that period, except that Lessee shall pay Lessor as
base rental for the period of such holdover an amount equal to 1.50 times the
base rent being paid by Lessee immediately prior to the expiration or
termination of the Lease. Lessee agrees to vacate and deliver the Leased
Premises to Lessor immediately upon Lessee's receipt of notice from Lessor to
vacate. Such notice may be given pursuant to the notice provisions of Section
14.07 herein. Lessee agrees to pay the rental payable during the holdover period
to Lessor on demand. No holding over by Lessee, whether with or without the
consent of Lessor and notwithstanding receipt by Lessee of an invoice from
Lessor for holdover rent, will extend the term of this Lease. Additionally,
Lessee shall pay to Lessor all damages sustained by Lessor as a result of such
holding over by Lessee.

                      ARTICLE 3.00   - OCCUPANCY AND USE

    3.01 Use. Lessee warrants and represents to Lessor that the Leased Premises
may be used and occupied only for the purpose as set forth in Section 1.06.
Lessee shall occupy the Leased Premises, conduct its business and control its
agents, employees, invitees and visitors in such a manner as is lawful,
reputable, will not create a nuisance, interfere with standard Building
operations, or affect the structural integrity or design capabilities of the
Building. Lessee shall not permit any operation which emits any odor or matter
which intrudes outside the Leased Premises, attracts rodents, use any apparatus
or machine which makes undue noise or causes vibration in any portion of the
Building or otherwise interfere with, annoy or disturb any other party outside
the Leased Premises, including without limitation, any other tenant in the
Building. Lessee shall neither permit any waste on the Leased Premises nor allow
the Leased Premises to be used in any way which would, in the reasonable opinion
of Lessor, be extra hazardous on account of fire or which would in any way
increase or render void the fire insurance on the Building. If at any time
during the Term the State Board of Insurance or other insurance authority
disallows any of Lessor's sprinkler credits or imposes an additional penalty or
surcharge in Lessor's insurance premiums because of Lessee's original or
subsequent placement or use of storage racks or bins, method of storage or
nature of Lessee's inventory or any other act of Lessee, Lessee agrees to pay as
additional rent the increase in Lessor's insurance premiums. Notwithstanding
anything set forth in this Section 3.01, in no way does Lessor warrant or
represent, either expressly or impliedly, that Lessee's use of the Leased
Premises is in accordance with applicable codes or ordinances of the

Lessee's option and expense, a free-standing "monument" sign consistent in
quality and appearance with the architectural standards of the Building, and as
approved in advance by Lessor. All signs must be in conformance with applicable
governmental requirements and limitations (including any applicable restrictive
covenants). Such permitted signs must be removed by Lessee upon expiration or
termination of the Lease at Lessee's sole cost and expense. Any damage or
discoloration from such removal will be repaired at Lessee's sole cost and
expense.

    3.03 Compliance with Laws, Rules and Regulations. Lessee, at Lessee's sole
cost and expense (except as provided in Section 2.04 hereof), shall comply with
all laws, ordinances, orders, rules and regulations now in effect or enacted
subsequent to the date hereof by state, federal, municipal or other agencies or
bodies having jurisdiction over Lessee or the use, condition and occupancy of
the Leased Premises except that Lessor shall be responsible for construction of
the Lessee Improvements in compliance therewith as of the Commencement Date,
including, but not limited to, compliance with the ADA as to the Building, but
excluding the interior of the Leased Premises which is Lessee's responsibility.
Lessee will comply with the rules and regulations of the Building adopted by
Lessor which are set forth on a schedule attached to this Lease. At any time,
Lessor may change and amend the rules and regulations in any reasonable manner
not inconsistent with the terms of this Lease as may be deemed advisable for the
safety, care, cleanliness, preservation of good order and operation or use of
the Building or the Leased Premises. All changes and amendments to the rules and
regulations of the Building will be sent by Lessor to Lessee in writing and must
thereafter be carried out and observed by Lessee.

    3.04 Warranty of Possession and Enjoyment. Lessor warrants that it has the
right and authority to execute this Lease, and Lessee, upon payment of the
required rents and subject to the terms, conditions, covenants and agreements
contained in this Lease, is entitled to possession and quiet enjoyment of the

renewal thereof. Lessor is not responsible for the acts or omissions of any
other lessee or third party that may interfere with Lessee's use and enjoyment
of the Leased Premises.

    3.05 Inspection. Lessor or its authorized agents may at any and all
reasonable times enter the Leased Premises to inspect the same, conduct tests,
environmental audits or other procedures to determine Lessee's compliance with
the terms hereof; to supply any other service to be provided by Lessor; to show
the Leased Premises to prospective purchasers, lessees, (within six months prior

Leased Premises or any other portion of the Building or for any other purpose
Lessor deems

Commercial Lease - Page 8 of 44

<PAGE>

reasonably necessary. LESSEE HEREBY WAIVES ANY CLAIM FOR DAMAGES FOR INJURY OR
INCONVENIENCE TO OR INTERFERENCE WITH LESSEE'S BUSINESS, ANY LOSS OF OCCUPANCY
OR USE OF THE LEASED PREMISES, AND ANY OTHER LOSS OCCASIONED BY INSPECTIONS MADE
UNDER THIS SECTION INCLUDING CLAIMS RESULTING FROM THE NEGLIGENCE OF LESSOR BUT
EXCLUDING ANY CLAIMS RESULTING FROM THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT
OF LESSOR. Lessee shall not change Lessor's lock system or in any other manner
prohibit Lessor from entering the Leased Premises. Lessor is entitled to use any
and all means which Lessor may deem proper to open any door in an emergency
without liability therefor. During the final one-hundred eighty days of the
Lease term, Lessor or its authorized agents have the right to erect or maintain
on or about the Leased Premises or the Building customary signs advertising the
Leased Premises for lease or sale.

    3.06 Hazardous Waste. The term "Hazardous Substances," as used in this Lease
means pollutants, contaminants, toxic or hazardous wastes, or any other
substances, the use and/or the removal of which is required or the use of which
is regulated, restricted, prohibited or penalized by any "Environmental Law,"
which term means any federal, state or local law, ordinance or other statute of
a governmental or quasi-governmental authority relating to pollution or
protection of the environment. Lessee hereby agrees that (i) no activity will be
conducted on the Leased Premises that will produce any Hazardous Substance,
except for such activities that are part of the ordinary course of Lessee's
business activities (the "Permitted Activities"), provided said Permitted
Activities are conducted in accordance with all Environmental Laws and have been
approved in advance in writing by Lessor; Lessee shall obtain all required
permits and pay all fees and conduct any testing required by any governmental
agency; (ii) the Leased Premises will not be used in any manner for the storage
of any Hazardous Substances except for the temporary storage of such materials
that are used in the ordinary course of Lessee's business (the "Permitted
Materials") provided such Permitted Materials are properly stored in a manner
and location meeting all Environmental Laws and approved in advance in writing
by Lessor; Lessee shall obtain all required permits and pay all fees and conduct
any testing required by any governmental agency in connection with the Permitted
Materials; (iii) no portion of the Leased Premises or Building will be used as a
landfill or a dump; (iv) Lessee will not install any underground or above ground
tanks of any type; (v) Lessee will not allow any surface or subsurface
conditions to exist or come into existence that constitute, or with the passage
of time may constitute a public or private nuisance; (vi) Lessee will not permit
any Hazardous Substances to be brought onto the Leased Premises or Building,
except for the Permitted Materials, and if so brought or found located thereon
(except for pre-existing conditions or matters caused by the Lessor), the same
must be immediately removed, with proper disposal, and all required cleanup
procedures must be diligently undertaken pursuant to all Environmental Laws.
Lessor or Lessor's representative's may, but are not required to, enter the
Leased Premises for the purpose of inspecting the storage, use and disposal of
Permitted Materials to ensure compliance with all Environmental Laws. Should it
be determined, in Lessor's sole opinion, that said Permitted Materials are being
improperly stored, used, or disposed of, then Lessee shall immediately take such
corrective action as requested by Lessor. Should Lessee fail to take such
corrective action within twenty-four (24) hours, Lessor has the right to perform
such work and Lessee shall promptly reimburse Lessor for any and all costs

Commercial Lease - Page 9 of 44

<PAGE>

associated with said work. If at any time during or after the term of the Lease,
the Leased Premises or Building are found to be so contaminated or subject to
said conditions as a result of Lessees breach of the terms of this Lease, Lessee
shall diligently institute proper and thorough cleanup procedures at Lessee's
sole cost. Before taking any action to comply with Environmental Laws or to
clean up Hazardous Substances contaminating the Leased Premises or Building,
Lessee shall submit to Lessor a plan of action, including any and all plans and
documents required by any Environmental Law to be submitted to a governmental
authority (collectively a "plan of action"). Such plan of action must be
implemented by a licensed environmental contractor. Before Lessee begins the
actions necessary to comply with Environmental Laws or to clean up contamination
from Hazardous Substances, Lessor must have (1) approved the nature, scope and
timing of the plan of action, and (2) approved any and all covenants and
agreements to effect the plan of action. Lessee agrees to indemnify and hold
Lessor harmless from all claims, demands, actions, liabilities, costs, expenses,
damages and obligations of any nature arising from or as a result of the use of
the Leased Premises or Building by Lessee in violation of this Section 3.06 but
excluding pre-existing conditions or matters resulting from the negligence or
willful misconduct of Lessor. The foregoing indemnification and the
responsibilities of Lessee survive the termination or expiration of this Lease.
Lessee represents that it has not been previously cited for any environmental
violations by any applicable governmental agency and that there are no Permitted
Materials to be stored in or upon the Leased Premises. In no event will any
Permitted Materials be stored in or upon the Leased Premises without Lessor's
prior written consent.

    3.07 Parking and Road Use. Except as the number of spaces may be reduced
pursuant to Section 3.08, Lessor will ensure that Lessee will have available to
use, for the benefit of Lessee, its employees, customers, invitees and
licensees, six (6) parking spaces for each 1000 rentable square feet of Leased
Premises in the parking areas adjacent to the Building of which the Leased
Premises are a part on an unassigned, unreserved basis, subject to reasonable
regulation by Lessor. Lessor may use additional parking spaces if available, on
a first come, first serve basis unless such use interferes with another tenant's
rights. Lessor reserves the right in its sole discretion to designate specific
areas within the parking areas for the exclusive use of visitors and invitees to
the Building and others. Included in the aggregate allowance of parking spaces
shall be five (5) designated, reserve parking spaces for the exclusive use of
Lessee, location of such spaces to be agreed upon by Lessor and Lessee and to be
shown on the site plan attached hereto as Exhibit "A", provided that Lessor
shall not be responsible for monitoring use of such spaces. Should Lessee
increase the square footage of the Leased Premises at any time, Lessee shall be
allowed additional parking spaces according to the ratio set forth herein. Any
parking permitted by Lessor on any common drive areas by Lessee or any of
Lessee's employees, customers, invitees or licensees will be permitted upon the
express condition that all such drives must be kept clear for through traffic of
all vehicles, including tractor-trailers. No driving or parking of any vehicles
on non-paved areas adjoining the Building or within the Project of which the
Building is a part is permitted. Lessee's failure to use all of the parking
spaces allocated to it under this Section will not constitute a waiver by Lessee
of the right to use those parking spaces at a later time.

    3.08 Satellite Dishes. Lessor agrees that Lessee may locate one or more
satellite dishes or other telecommunications equipment on the roof of the
Building or on the land on

Commercial Lease - Page 10 of 44

<PAGE>

which the Building is constructed, provided the placement of the satellite
dishes or other telecommunications equipment does not effect the structural
integrity of the Building or materially impair the appearance of the Building or
the land on which the Building is constructed and Lessee obtains Lessor's
written approval as to location and size of satellite prior to the installation
of such.

                 ARTICLE 4.00   - UTILITIES, SERVICE, SIGNAGE

    4.01 Security Lighting. Lessor shall install security lighting at all
entrances to the Leased Premises and in the parking lots adjacent to the Leased
Premises at its expense; provided, however, the Lessor shall make no
representation or warranty as to the sufficiency or adequacy of such lighting or
the effectiveness thereof for security.

    4.02 Building Services. Lessor shall provide the normal utility service
connections to the Building. Lessee shall pay directly to the appropriate
supplier the cost of all utility services to the Leased Premises, including, but
not limited to, any required security deposits and initial connection charge,
all charges for gas, electricity, telephone, water, sanitary and storm sewer
service and security systems. If any services are jointly metered with other
Leased Premises or property (for example, exterior lighting), Lessor shall make
a reasonable determination of Lessee's proportionate share of the cost of such
services and Lessee shall pay such share to Lessor within ten (10) days of
receipt of any invoice thereof. Lessee shall pay all costs caused by Lessee
introducing excessive pollutants or solids other than ordinary human waste into
the sanitary sewer system, including permits, fees and charges levied by any
governmental subdivision for any such pollutants or solids. Lessee shall be
responsible for the installation and maintenance of any dilution tanks, holding
tanks, settling tanks, sewer sampling devices, sand traps, grease traps or
similar devices as may be required by any governmental subdivision for Lessee's
use of the sanitary sewer system. If the Leased Premises are in a multi-
occupancy Building, Lessee shall pay all surcharges levied due to Lessee's use
of sanitary sewer or waste removal services insofar as such surcharges affect
Lessor or other Lessees in the Building. Except as set forth herein, Lessor
shall not be required to pay for any utility service, supplies or upkeep in
connection with the Leased Premises or Building. Utility services for the common
areas shall be part of Operating Expenses.

    Lessee agrees that Lessor is not liable to Lessee in any respect for damages
to either person, property or business on account of any interruption or failure
of utilities or services furnished by Lessor provided that Lessor uses
reasonable diligence to repair the same promptly. No such interruption or
failure may be construed as an eviction of Lessee or entitle Lessee to (i) any
abatement of rent, (ii) terminate the Lease, or (iii) be relieved from
fulfilling any covenant or agreement contained herein. Should any malfunction of
the improvements or facilities to the Leased Premises or Building (which by
definition do not include any improvements or facilities of Lessee above
Building standard improvements) occur for any reason, Lessor shall use
reasonable diligence to repair same promptly, but Lessee will not be entitled to
any claim for rebate or abatement of rent or damages on account of such
malfunction or of any interruptions in service occasioned thereby or resulting
therefrom.

    4.03 Theft or Burglary. Lessee expressly acknowledges that whether or not
Lessor, from time to time, elects to provide security services, Lessor has not,
nor will Lessor be deemed to have, warranted the efficiency of any security
personnel, service, procedures or equipment and Lessor is not liable in any
manner for the failure of any of the foregoing to prevent or control or
apprehend anyone suspected of theft, personal injury, property damage or any
criminal conduct in, on or around the Building. Lessee agrees that Lessor is not
liable to Lessee for losses to Lessee's property or personal injury caused by
criminal acts or entry by unauthorized persons into the Leased Premises. Lessee
is responsible for the cost of repairs of damage and restoration of the Leased
Premises following any such act.

                   ARTICLE 5.00   - REPAIRS AND MAINTENANCE

    5.01 Existing Conditions. On the Commencement Date, Lessee shall be deemed
to have accepted the Leased Premises in their then existing condition, subject
to all recorded matters, laws, ordinances, and governmental regulations and
orders; provided that, Lessee's acceptance of the Leased Premises shall not
relieve Lessor from any maintenance and repair obligations under this Lease.
Lessee acknowledges that neither Lessor nor any agent of Lessor has made any
warranty or representation of any kind, either express or implied as to the
condition of the Leased Premises or the suitability of the Leased Premises for
Lessee's intended use other than that the Leased Premises will be constructed in
accordance with the Lessee Improvements Final Plans and Specifications and will
be free from Hazardous Materials. The taking of the possession of the Leased
Premises by Lessee is intended by the parties to be conclusive evidence that
Lessee accepts the Leased Premises and Lessor has complied with its obligations
of Section 6.01 herein except for Defects (as defined in Section 2.04 hereof),
the presence of Hazardous Materials, and punch list items. Prior to taking
occupancy of the Leased Premises, Lessee shall sign a copy of the space plan of
the Leased Premises acknowledging its condition on the date thereof (unless
Lessor waives such requirement) and execute the Certificate of Acceptance form
attached as Exhibit "D" accepting such condition of the Premises except for
Defects, the presence of Hazardous Materials and punch list items.

    5.02 Lessor Repairs And Maintenance. Lessor shall manage the Building in
accordance with property management standards customary to the area and will
keep the Building in compliance with all legal and regulatory requirements
(including Environmental Laws, Americans with Disabilities Act, and municipal
codes and ordinances). Lessor agrees to indemnify and hold Lessee harmless from
all claims, demands, actions, liabilities, costs, expenses, damages and
obligations of any nature arising from or as a result of the failure of the
building to be in compliance with applicable laws and regulation. Lessor is not
required to make any improvements, replacements or repairs of any kind or
character to the Leased Premises during the Term. Lessor shall maintain the
roof, foundation and structural soundness of exterior walls of the Building,
mechanical, electrical and plumbing systems serving the Building and common
areas, in good repair and condition except for reasonable wear and tear. Lessor
shall also perform all ground maintenance, landscaping, pest control, and
removal of debris from outside receptacles. Lessee agrees that Lessor is not
liable to Lessee, except as expressly provided in this Lease, for any damage or
inconvenience, and Lessee is not entitled to any abatement or reduction of rent
by reason of any repairs, reasonable alterations or additions made by Lessor
under this Lease. Should Lessor not repair or maintain the Building or the
Leased

Commercial Lease - Page 12 of 44

<PAGE>

Premises as required hereunder, after providing written notice to Lessor and
after a thirty (30) day opportunity to cure by Lessor, or such longer period as
shall be necessary, provided that Lessor has not commenced such repair within
such 30 day period and has not diligently pursued same thereafter, Lessee may
make such repairs or perform such maintenance and Lessor shall promptly
reimburse Lessee for any reasonable expenses incurred by Lessee in performing
such work, or if the Leased Premises are untenantable, Lessee may terminate this
Lease.

    5.03 Lessee Repairs And Maintenance. Lessee shall, at its sole cost and
expense, maintain and repair the Leased Premises in good repair and condition,
including, but not limited to carpet or other floor covering, interior
partitions, doors, interior side of dernising(??sp??) walls, telephone and
computer cabling that serves Lessee's equipment exclusively, any supplemental
air conditioning, interior water closets, kitchens and plumbing in connection
therewith and any alterations, additions or improvements made by or on behalf of
Lessee. Lessee shall take good care of all personal property and fixtures
located within the Leased Premises. Lessee shall repair and pay for any damage
caused by any act or omission of Lessee or Lessee's agents, employees, invitees,
licensees or visitors to the Leased Premises, the Building, or the project. If
Lessee fails to maintain, repair or replace promptly as required herein, Lessor
may, at its option, and following at least thirty (30) days' advance written
notice to Lessee, perform on Lessee's behalf and charge the cost of such
performance to Lessee as additional rent which is due and payable by Lessee
within ten (10) days from receipt of Lessor's invoice. Costs incurred under this
section are the total responsibility of Lessee.

    5.04 Request for Repairs. All requests for repairs or maintenance that are
the responsibility of Lessor pursuant to any provision of this Lease must be
made in writing to Lessor at the address in Section 1.05 and delivered pursuant
to Section 14.07. After receipt of written notice, Lessor is entitled to a
reasonable time within which to perform such repairs or maintenance.

    5.05 Lessee Damages. Lessee shall not allow any damage to be committed on
any portion of the Leased Premises or Building, and at the termination of this
Lease, by lapse of time or otherwise, Lessee shall deliver the Leased Premises
to Lessor in as good condition as existed at the Commencement Date of this
Lease, ordinary wear and tear and casualty loss excepted. Lessor's standard
move-out checklist will be followed by Lessee to ensure compliance with this
provision. The cost and expense of any repairs necessary to restore the
condition of the Leased Premises must be borne by Lessee. Should Lessor be
required to expend any sums to ensure compliance with this Section 5.05, Lessee
shall reimburse Lessor within ten (10) days of receipt of notice from Lessor.

    5.06 Maintenance Contract. Lessor may, as an Operating Expenses, during the
term of this Lease maintain a regularly scheduled preventative
maintenance/service contract on an annual basis with a maintenance contractor
for the servicing of all general sprinkler systems, hot water, heating and air
conditioning systems and equipment within or servicing the Building. Lessee
shall maintain, at Lessee's sole cost and expense, a regularly scheduled
preventative maintenance/service contract on an annual basis with a maintenance
contractor for the servicing of all hot water, heating and air conditioning
systems within or exclusively servicing the Leased Premises.

                 ARTICLE 6.00   - ALTERATIONS AND IMPROVEMENTS

6.01  Initial Lessee Improvements.

      A. Lessee Improvements. Lessee shall prepare final plans and
      specifications for construction of the Lessee Improvements desired by
      Lessee and shall deliver to Lessor by July 1, 1999, two (2) copies of such
      plans and specifications and the names of two proposed contractors to
      construct the Lessee Improvements for Lessor approval. Lessor will
      promptly either approve of the plans and specifications and the
      contractors, or communicate its objections, and if Lessor has objections,
      the Lessor will work diligently with Lessee to resolve any objections such
      that approval of the plans and specifications and names of contractors is
      given within fifteen (15) days of receipt. Lessor shall be deemed to have
      approved the plans and specifications and the contractors unless Lessor
      shall have provided written notice to Lessee of Lessor's objections
      thereto within fourteen (14) days following the delivery thereof by Lessee
      to Lessor. The Lessor approved final plans and specifications for the
      Lessee Improvements are herein called the "Lessee Improvements Final Plans
      and Specifications". All reasonable costs involved in approving, drafting
      and preparing the Lessee Improvements Final Plans and Specifications shall
      be charged against the Improvement Allowance described below. Lessor shall
      apply for building permits to construct the Lessee Improvements and will
      submit bid requests to the two contractors selected by Lessee and the
      contractor for the Shell Building Improvements no later than two (2) days
      following approval of the Lessee Improvements Final Plans and
      Specifications. Contractors will be required to submit their bids no later
      than thirty (30) days following receipt of the bid request. Lessee shall
      have fifteen (15) days from receipt of all bids to select the contractor
      for the Lessee Improvements. Except for immaterial field changes,
      modifications to the Lessee Improvements Final Plans and Specifications
      must be made and accepted only by written change order or agreement signed
      by Lessor and Lessee and will constitute an amendment to this Lease.
      Lessee shall be responsible for payment in advance of all work and
      construction resulting from changes in the Lessee Improvements Final Plans
      and Specifications requested by Lessee if the additional cost attributable
      to the changes exceed the Improvement Allowance by more than $3.00 as
      described in subparagraph (c) below. The Lessee Improvements Final Plans
      and Specifications (when approved by Lessor and Lessee) are incorporated
      in this Lease by reference. For the purpose of this Section, an
      "immaterial field change" shall mean such field changes which are required
      by any governmental authority or changes which (i) do not affect the size,
      configuration, structural integrity, quality, character, architectural
      appearance and standard of workmanship contemplated in the Lessee
      Improvements Final Plans and Specifications, (ii) will not result in any
      default in any obligation to any person or violation of any governmental
      requirements, and (iii) the cost of or reduction resulting from any single
      field change or extra does not exceed $5,000.00.

                        Commercial Lease - Page 14 of 44
<PAGE>

          B. Subject to the Lessee's payment obligations under (c) below, Lessor
          shall cause the Lessee Improvements to be completed in a good and
          workmanlike manner, in accordance with all applicable laws and
          regulations, and in accordance with the Lessee Improvements Final
          Plans and Specifications. Lessor shall coordinate construction of
          Lessee Improvements, keeping Lessee informed on the progress of the
          work and of any expenditures made to perform such work and for such
          services shall be paid a construction management fee of five percent
          (5%) of the Hard Costs of such Lessee Improvements, which fee shall be
          paid out of the Improvement Allowance (as hereinafter defined). "Hard
          Costs" are the costs of labor, material and permits and licenses
          necessary to construct the Lessee Improvements, and do not include any
          legal, architectural, management or engineering expenses. Lessor
          agrees that all construction contracts and architectural contracts
          shall provide that the general contractor and architect for the
          project shall provide status reports and other reports relating to the
          construction of the Lessee Improvements to Lessee as well as to
          Lessor, and Lessee shall have the right at any and all times to
          inspect the Lessee Improvements at all stages of construction. Lessor
          agrees to cooperate with Lessee on any changes to the Lessee
          Improvements and agrees to provide to Lessee copies of all draw
          requests and the underlying documentation relating to the draw
          requests to Lessee. Lessor agrees to keep the Leased Premises free
          from any and all mechanic's or materialman's liens and to pay promptly
          for all work to be performed relative to the construction project. In
          the event any such lien attaches to the Leased Premises as a result of
          Lessor's actions, and if Lessor does not contest the lien diligently
          and in good faith or does not proceed in its effort to remove the
          lien, then, in addition to any other right or remedy of Lessee, Lessee
          may, but is not obligated to, obtain the release or otherwise
          discharge the same or to obtain a bond in satisfaction of same. Any
          amount paid by Lessee in order to release or discharge any such lien
          must be paid by Lessor to Lessee on demand.

          C. Lessor shall provide Lessee with an improvement allowance of $22.00
          per rentable square foot of the Leased Premises (the "Improvement
          Allowance"). The Improvement Allowance shall be paid out from time to
          time to pay for costs incurred by Lessor in connection with the Lessee
          Improvements, including costs of Lessee's architect and/or space
          planner, the construction management fee of five percent (5%) of the
          Hard Costs of construction, and third party contractors as the Lessee
          Improvements progress. Lessee shall pay those costs of construction of
          the Lessee Improvements in excess of the Improvement Allowance, if
          any, and such amounts shall be paid by Lessee to Lessor within thirty
          (30) days following receipt by Lessee of a written request therefor
          from Lessor. In the event the costs and expenses of the Lessee
          Improvements shall exceed the Improvement Allowance, then at the
          option of Lessee and upon written request by Lessee and approval by
          Lessor's mortgagee/lender, the Lessor shall fund up to $3.00 per
          rentable square foot within the Leased Premises of such excess amounts
          and such excess amounts so funded by Lessor shall be paid by Lessee to
          Lessor as additional monthly rent. The amount to be added on a monthly
          basis to Base Rent

Commercial Lease - Page 15 of 44
<PAGE>

          shall be that monthly amount necessary to fully amortize, on a
          straight line basis, the excess amount over the term of this Lease at
          a ten percent (10%) interest rate.

     6.02 Additional Lessee Improvements. Except as provided in Section 6.01
above, Lessee shall not make or allow to be made any material alterations or
physical additions in or to the Leased Premises without complying with all
local, state and federal ordinances, laws, statutes and without first obtaining
the written consent of Lessor, which consent may not be unreasonably withheld.
In any event, Lessee shall provide Lessor with a copy of the plans and
specifications for any such alterations or improvements. Any alterations,
physical additions or improvements to the Leased Premises (including Lessee
Improvements) made by Lessor or Lessee become the property of Lessor and must be
surrendered to Lessor upon the termination of this Lease without credit to
Lessee. This clause does not apply to moveable equipment, trade fixtures,
personal property or furniture owned by Lessee, which may be removed by Lessee
at the end of the term of this Lease if Lessee is not then in default, if such
equipment and furniture are not then subject to any other rights, liens and
interest of Lessor and such removal can be accomplished without material damage
to the Leased Premises and, if there shall exist any damage caused by such
removal, such damage shall be repaired by Lessee. Upon completion of any such
work by Lessee, Lessee shall provide Lessor with "as built plans", copies of all
construction contracts and proof of payment for all labor and materials.
Notwithstanding the above, Lessee shall be allowed, without prior approval of
Lessor, to make $5,000.00 in non-structural alterations in any one calendar
year, not to exceed an aggregate of $25,000.00 over the initial term of the
Lease.

     6.03  Mechanic's Lien. Lessee will not permit any mechanic's or
materialman's lien(s) or other lien to be placed upon the Leased Premises or the
Building and nothing in the Lease is intended in any way to constitute the
consent by (or request of) Lessor, express or implied, by inference or
otherwise, to any person for the performance of any labor or the furnishing of
any materials to the Leased Premises, or any part that would give the rise to
any mechanic's or materialman's or other lien against the Leased Premises. In
the event any such lien attaches to the Leased Premises as a result of Lessee's
actions, and if Lessee does not contest the lien diligently and in good faith or
does not succeed in its effort to remove the lien, then, in addition to any
other fight or remedy of Lessor, Lessor may, but is not obligated to, obtain the
release or otherwise discharge the same or to obtain a bond in satisfaction of
same. Any amount paid by Lessor in order to release or discharge any such lien
must be paid by Lessee to Lessor on demand as additional rent.

                    ARTICLE 7.00   - CASUALTY AND INSURANCE

     7.01  Substantial Destruction. If the Leased Premises or any part thereof
are damaged by fire or other casualty, Lessee shall give prompt written notice
thereof to Lessor. 1) If the Leased Premises are totally destroyed by fire or
other casualty, 2) if the Leased Premises are damaged so that rebuilding cannot
reasonably be completed within one hundred eighty (180) days after the date of
written notification by Lessee to Lessor of the destruction, 3) if the Leased
Premises are part of a Building which is substantially destroyed (even though
the Leased Premises are not totally or substantially destroyed), 4) if the
Leased Premises or Building is damaged by fire or other casualty and applicable
law would prevent rebuilding to substantially

Commercial Lease - Page 16 of 44
<PAGE>

the condition prior to such fire or casualty, 5) if any mortgagee requires the
insurance proceeds payable as a result of such casualty to be applied to the
payment of the mortgage debt or 6) the Leased Premises are materially damaged
and less than two (2) years remain on the Term on the date of such casualty,
Lessor or Lessee may at their option terminate this Lease by providing the other
written notice thereof within sixty (60) days of such casualty and all
obligations under the Lease shall terminate as of the date of the casualty;
provided, however, Lessee shall not have the right to terminate this Lease if
Lessor has theretofore commenced and is diligently pursuing rebuilding.

     7.02  Partial Destruction. If this Lease is not terminated under Section
7.01, Lessor shall at its sole risk and expense proceed with reasonable
diligence to rebuild or repair the Building or other improvements to
substantially the same condition in which they existed prior to the damage,
provided, Lessor has no obligation to repair or rebuild Lessee's furniture,
fixtures or personal property. If the destruction was caused by an act or
omission of Lessee, its employees, agents, or invitees, Lessee shall pay Lessor
the difference between the actual cost of rebuilding or repairing the Leased
Premises and any insurance proceeds received by Lessor. If the Leased Premises
are to be rebuilt or repaired and are untenantable in whole or in part following
the damage, either because of the damage or the rebuilding or repairing, and the
damage or destruction was not caused or substantially contributed to by any act
or negligence of Lessee, its agents, employees, invitees or those for whom
Lessee is responsible, the rent payable under this Lease during the period for
which the Leased Premises are untenantable will be adjusted to such an extent as
may be fair and reasonable under the circumstances. If Lessor fails to complete
the necessary repairs or rebuilding within one hundred fifty days from the date
of the destruction, Lessee may at its option terminate this Lease by delivering
written notice of termination to Lessor, whereupon all rights and obligations
under this Lease cease to exist. If any damage or destruction occurs to the
Leased Premises during the last twenty-four (24) months of the Lease term,
Lessor may elect to terminate this Lease as of the date Lessee notifies Lessor
of such damage. Lessor and Lessee hereby waive the provisions of any law from
time to time in effect during the Term relating to the effect upon leases of
partial or total destruction of Leased property and agree that their respective
rights in the event of damage or destruction are those specifically set forth
herein.

     7.03  Property Insurance. Lessor shall at all times during the term of
this Lease maintain a policy or policies of insurance with the premiums paid in
advance, issued by and binding upon some solvent insurance company having an "A"
rating or better, insuring the Building against all risk of direct physical loss
in an amount equal to the full replacement cost of the Building structure and
its improvements as of the date of the loss, providing protection against all
perils, including, without limitations fire, extended coverage, vandalism,
malicious mischief, a standard mortgagee clause and rental coverage; provided,
Lessor is not obligated in any way or manner to insure any personal property
(including, but not limited to, any furniture, machinery, goods or supplies) of
Lessee upon or within the Leased Premises, any fixtures installed or paid for by
Lessee upon or within the Leased Premises, or any improvements which Lessee may
construct on the Leased Premises. The rental insurance policy will be for the
full rental value for a period of one year, which insurance also covers real
estate taxes, insurance and other amounts which might be due Lessor from Lessee
pursuant to the terms of this Lease. Lessee agrees that it is not entitled to
the proceeds of any policy of insurance maintained by

Commercial Lease - Page 17 of 44
<PAGE>

Lessor even if the cost of such insurance is borne by Lessee as set forth in
Article 2.00. Notwithstanding the foregoing, in the event Lessor has a net worth
in excess of $50,000,000, it shall be entitled to self insure against all risk
provided for in this paragraph in lieu of obtaining the insurance set forth
herein.

     7.04  Waiver of Subrogation. ANYTHING IN THIS LEASE TO THE CONTRARY NOT
WITHSTANDING, LESSOR AND LESSEE HEREBY WAIVE AND RELEASE EACH OTHER OF AND FROM
ANY AND ALL RIGHT OF RECOVERY, CLAIM, ACTION OR CAUSE OF ACTION, AGAINST EACH
OTHER, THEIR AGENTS, OFFICERS AND EMPLOYEES, FOR ANY LOSS OR DAMAGE THAT MAY
OCCUR TO THE LEASED PREMISES, IMPROVEMENTS TO THE BUILDING OF WHICH THE LEASED
PREMISES ARE A PART, OR PERSONAL PROPERTY WITHIN THE BUILDING, BY REASON OF
FIRE, EXPLOSION, OR ANY OTHER OCCURRENCE, REGARDLESS OF CAUSE OR ORIGIN,
INCLUDING NEGLIGENCE OF LESSOR OR LESSEE AND THEIR AGENTS, OFFICERS AND
EMPLOYEES. LESSOR AND LESSEE AGREE IMMEDIATELY TO GIVE THEIR RESPECTIVE
INSURANCE COMPANIES WHICH HAVE ISSUED POLICIES OF INSURANCE COVERING ALL RISK OF
DIRECT PHYSICAL LOSS, WRITTEN NOTICE OF THE TERMS OF THE MUTUAL WAIVERS
CONTAINED IN THIS SECTION AND TO HAVE THE INSURANCE POLICIES PROPERLY ENDORSED,
IF NECESSARY, TO PREVENT THE INVALIDATION OF THE INSURANCE COVERAGE BY REASON OF
THE MUTUAL WAIVERS.

     7.05  Hold Harmless. Lessor will not be liable to Lessee's employees,
agents, invitees, licensees or visitors, or to any other person, for an injury
to person or damage to property on or about the Leased Premises caused by any
act or omission of Lessee, its agents, servants or employees, any tenant in the
Building of which the Leased Premises are a part, or of any other person
entering upon the Leased Premises under express or implied invitation by Lessee,
the failure or cessation of any service provided by Lessor (including security
service and devices or caused by leakage of gas, oil, water or steam or by
electricity emanating from the Leased Premises) except as provided in this
Lease. Lessee agrees to indemnify and hold harmless Lessor of and from any loss,
attorney's fees, expenses or claims arising out of any such damage or injury
except for damages or injury caused by Lessor's negligence, recklessness or
willful misconduct.

     7.06

          A. At all times commencing on and after the earlier of the
          Commencement Date and the date Lessee or its agents, employees or
          contractors enters the Leased Premises for any purpose, Lessee shall
          carry and maintain, at its sole cost and expense:

             1.  Commercial General Liability Insurance applicable to the Leased
                 Premises and its appurtenances providing, on an occurrence
                 basis, a minimum combined single limit of Two Million Dollars
                 ($2,000,000.00), with a contractual liability endorsement
                 covering Lessee's indemnity obligations under this Lease;

Commercial Lease - Page 18 of 44
<PAGE>

               2.  All Risks of Physical Loss Insurance written at replacement
                   cost value and with a replacement cost endorsement covering
                   all of Lessee's personal property and improvements in the
                   Leased Premises;

               3.  Workers' Compensation Insurance as required by the state in
                   which the Leased Premises is located and in amounts as may be
                   required by applicable statute;

               4.  Business interruption or loss of income insurance in amounts
                   satisfactory to Lessor; and

               5.  Whenever good business practice, in Lessor's reasonable
                   judgment, indicates the need of additional insurance coverage
                   or different types of insurance in connection with the Leased
                   Premises or Lessee's use and occupancy thereof, Lessee shall,
                   upon request, obtain such insurance at Lessee's expense and
                   provide Lessor with evidence thereof.

          B. Before any repairs, alterations, additions, improvements, or
          construction are undertaken by or on behalf of Lessee, Lessee shall
          carry and maintain, at its expense, or Lessee shall require any
          contractor performing work on the Leased Premises to carry and
          maintain, at no expense to Lessor, in addition to Workers'
          Compensation Insurance as required by the jurisdiction in which the
          Building is located, All Risk Builder's Risk Insurance in the amount
          of the replacement cost of any alterations, additions or improvements
          (or such other amount reasonably required by Lessor) and Commercial
          General Liability Insurance (including, without limitation,
          Contractor's Liability coverage, Contractual Liability coverage and
          Completed Operations coverage,) written on an occurrence basis with a
          minimum combined single limit of Two Million Dollars ($2,000,000.00)
          and adding "the named Lessor hereunder (or any successor thereto), and
          its respective members, principals, beneficiaries, partners, officers,
          directors, employees, agents and any Mortgagee(s)", and other
          designees of Lessor as the interest of such designees appear, as
          additional insureds (collectively referred to as the "Additional
          Insureds").

          C. Any company writing any insurance which Lessee is required to
          maintain or cause to be maintained pursuant to the terms of this Lease
          (all such insurance as well as any other insurance pertaining to the
          Leased Premises or the operation of Lessee's business therein being
          referred to as "Lessee's Insurance"), as well as the form of such
          insurance, are at all times subject to Lessor's reasonable approval,
          and each such insurance company must have an A.M. Best rating of "A-"
          or better and be licensed and qualified to do business in the state in
          which the Leased Premises are located. All policies evidencing
          Lessee's Insurance (except for Workers' Compensation Insurance) must
          specify Lessee as named insured and the Additional Insureds as
          additional insureds. Provided that the coverage afforded Lessor and
          any designees of Lessor is not reduced or otherwise adversely
          affected, all of Lessee's Insurance may be carried under a blanket
          policy covering

Commercial Lease - Page 19 of 44
<PAGE>

           the Leased Premises and any other of Lessee's locations. All policies
           of Lessee's Insurance must contain endorsements requiring that the
           insurer(s) give Lessor and its designees at least thirty (30) days'
           advance written notice of any change, cancellation, termination or
           lapse of said insurance. Lessee shall be solely responsible for
           payment of premiums for all of Lessee's Insurance. Lessee shall
           deliver to Lessor at least fifteen (15) days prior to the time
           Lessee's Insurance is first required to be carried by Lessee, and
           upon renewals at least fifteen (15) days prior to the expiration of
           any such insurance coverage, certified copies of all policies
           procured by Lessee in compliance with its obligations under this
           Lease. The limits of Lessee's Insurance do not in any manner limit
           Lessee's liability under this Lease.

           D. Lessee shall not do or fail to do anything in, upon or about the
           Leased Premises which will (1) violate the terms of any of Lessor's
           insurance policies; (2) prevent Lessor from obtaining policies of
           insurance acceptable to Lessor or any Mortgagees; or (3) result in an
           increase in the rate of any insurance on the Leased Premises, the
           Building, any other property of Lessor or of others within the
           Building. In the event of the occurrence of any of the events set
           forth in this Section, Lessee shall pay Lessor upon demand, as
           additional rent, the cost of the amount of any increase in any such
           insurance premium, provided that the acceptance by Lessor of such
           payment may not be construed to be a waiver of any rights by Lessor
           in connection with a default by Lessee under the Lease. If Lessee
           fails to obtain the insurance coverage required by this Lease, Lessor
           may, at its option, obtain such insurance for Lessee, and Lessee
           shall pay, as additional rent, the cost of all premiums thereon and
           all of Lessor's costs associated therewith.

                         ARTICLE 8.00   - CONDEMNATION

     8.01  Substantial Taking.  If all or a substantial portion of the Leased
Premises or a substantial portion of the Building of which the Leased Premises
are a part (even though the Leased Premises are not taken) 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 the taking
would prevent or materially interfere with the use of the Leased Premises or the
Building of which the Leased Premises are a part for the purpose for which it is
then being used, then Lessor and Lessee have the option to terminate this Lease
and to abate the rent during the unexpired portion of this Lease effective on
the date title or physical possession is taken by the condemning authority,
whichever occurs first. All proceeds of any taking are the sole property of
Lessor and Lessee agrees that Lessee is not entitled to any condemnation award
or proceeds in lieu thereof.

     8.02  Partial Taking.  If a portion of the Leased Premises or a portion
of the Building of which the Leased Premises are a part are taken for any public
or quasipublic 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 8.01 above, Lessor shall at Lessor's sole risk
and expense, restore and reconstruct the Building and other improvements on the
Leased Premises to the extent necessary to make it reasonably tenantable;
provided, if the

Commercial Lease - Page 20 of 44
<PAGE>

damages received by Lessor are insufficient to cover the costs of restoration,
Lessor may terminate this Lease. The rent payable under this Lease during the
unexpired portion of the term will be adjusted to such an extent as may be fair
and reasonable under the circumstances. All proceeds of any taking are the sole
property of Lessor and Lessee agrees that Lessee is not entitled to any
condemnation award or proceeds in lieu thereof.

                    ARTICLE 9.00   - ASSIGNMENT OR SUBLEASE

     9.01  Lessor Assignment.  Lessor may sell, transfer or assign, in whole
or in part, its rights and obligations under this Lease and in the Leased
Premises. Any such sale, transfer or assignment will release Lessor from any and
all liabilities under this Lease arising after the date of such sale, assignment
or transfer, so long as such transferee or assignee assumes the obligations of
Lessor hereunder.

     9.02  Lessee Assignment.  Except for an assignment to an affiliate and
except in the case of a merger or consolidation by Lessee with or into another
entity, Lessee shall not assign, in whole or in part, this Lease, or allow it to
be assigned, in whole or in part, or mortgage or pledge the same or sublet the
Leased Premises, in whole or in part, without the prior written consent of
Lessor which consent may not be unreasonably withheld, and in no event will any
such assignment or sublease ever release Lessee or any guarantor from any
obligation or liability hereunder unless consented to by Lessor. No assignee or
sublessee of the Leased Premises or any portion thereof may assign or sublet the
Leased Premises or any portion thereof.

     9.03  Conditions of Assignment.  If Lessee desires to assign or sublet
all or any part of the Leased Premises or grant any license, concession or other
right of occupancy of any portion of the Leased Premises, it must so notify
Lessor at least thirty days in advance of the date on which Lessee desires to
make such assignment or sublease. Lessee must provide Lessor with a copy of the
proposed assignment or sublease and such information as Lessor might reasonably
request concerning the proposed sublessee or assignee to allow Lessor to make
informed judgments as to the financial condition, reputation, operations and
general desirability of the proposed sublessee or assignee. Within fifteen days
after Lessor's receipt of Lessee's proposed assignment or sublease and all
required information concerning the proposed sublessee or assignee, Lessor may,
in its reasonable discretion, either: (1) consent to the proposed assignment or
sublease, or (2) refuse to consent to the proposed assignment or sublease, which
refusal is deemed to have been exercised unless Lessor gives Lessee written
notice providing otherwise. Upon the occurrence of an event of default, if all
or any part of the Leased Premises are then assigned or sublet, Lessor, 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 Lessee by reason of the assignment or sublease, and Lessor will
be entitled to a security interest in all properties on the Leased Premises to
secure payment of such sums. Lessee agrees that any collection directly by
Lessor from the assignee or sublessee is not intended to constitute a novation
or a release of Lessee or any guarantor from the further performance of its
obligations under this Lease.

     9.04  Subordination.  Lessee accepts this Lease subject and subordinate
to any recorded mortgage or deed of trust lien presently existing or hereafter
created upon the Building

Commercial Lease - Page 21 of 44
<PAGE>

or project of which the Leased Premises are a part (provided, however, that any
such mortgagee may, at any time, subordinate such mortgage, deed of trust or
other lien to this Lease) and to all existing recorded restrictions, covenants,
easements and agreements with respect to the Building and to any renewals
thereof. Lessee agrees that this clause is self-operative and no further
instrument of subordination is required to effect such subordination. Lessor is
hereby irrevocably vested with full power and authority to subordinate Lessee's
interest under this Lease to any first mortgage or deed of trust lien hereafter
placed on the Leased Premises, and Lessee agrees upon demand to execute
additional reasonable instruments subordinating this Lease as Lessor may
require. If the interests of Lessor under this Lease are transferred by reason
of foreclosure or other proceedings for enforcement of any first mortgage or
deed of trust lien on the Leased Premises, Lessee is bound to the transferee
(sometimes called the "Purchaser") at the option of the Purchaser, under the
terms, covenants and conditions of this Lease for the balance of the term
remaining, including any extensions or renewals, with the same force and effect
as if the Purchaser were Lessor under this Lease, and, if requested by the
Purchaser, Lessee agrees to attorn to the Purchaser, including the first
mortgagee under any such mortgage if it be the Purchaser, as its Lessor. Lessee
will not be entitled to any credits as against Purchaser any prepaid rents or
offsets against or credits due from Lessor, except as provided under the terms
of any non-disturbance agreement provided pursuant to Section 13.14 of this
Lease.

     9.05  Estoppel Certificates.  Lessee agrees to furnish, from time to time,
within ten (10) days after receipt of a request from Lessor, Lessor's mortgagee
or any potential purchaser of the Building, a statement certifying, if
applicable, the following: Lessee is in possession of the Leased Premises; the
Leased Premises are acceptable; the Lease is in full force and effect; the Lease
is unmodified; Lessee claims no present charge, lien, or claim of offset against
rent; the rent is paid for the current month, but is not prepaid for more than
one month and will not be prepaid for more than one month in advance; there is
no existing default by reason of some act or omission by Lessor; and such other
matters as may be reasonably required by Lessor, Lessor's mortgagee or any
potential purchaser. Lessee's failure to deliver such statement, in addition to
being a default under this Lease, may be deemed to establish conclusively that
this Lease is in full force and effect except as declared by Lessor, that Lessor
is not in default of any of its obligations under this Lease and that Lessor has
not received more than one month's rent in advance. Any notice and cure
provisions set forth in any other part of this Lease does not apply to a default
of this Section 9.05.

                            ARTICLE 10.00   - LIENS

     10.01  Landlord's Lien.  As security for payment of rent, damages and all
other payments required to be made by this Lease, Lessee hereby grants to Lessor
a lien upon all property of Lessee now or subsequently located upon the Leased
Premises and Lessee agrees to not remove such property from the Leased Premises
except in the ordinary course of business, provided at the time of such removal
Lessee is not in default. If Lessee abandons or vacates any substantial portion
of the Leased Premises or is in default in the payment of any rentals, damages
or other payments required to be made by this Lease or is in default of any
other provision of this Lease, Lessor may enter upon the Leased Premises, by
picking or changing locks if necessary, and take possession of all or any part
of the personal property, and may sell all or any part of the personal property
at a public or private sale, in one or successive sales, with or without notice,
to

Commercial Lease - Page 22 of 44
<PAGE>

the highest bidder for cash, and, on behalf of Lessee, sell and convey all or
part of the personal property to the highest bidder, delivering to the highest
bidder all of Lessee's title and interest in the personal property sold. The
proceeds of the sale of the personal property shall be applied by Lessor toward
the reasonable costs and expenses of the sale, including attorney's fees, and
then toward the payment of all sums then due by Lessee to Lessor under the terms
of this Lease. Any excess remaining will be paid to Lessee or any other person
entitled thereto by law.

     10.02  Uniform Commercial Code.  This Lease is intended as and constitutes
a security agreement within the meaning of the Uniform Commercial Code of the
state in which the Leased Premises are situated. Lessor, in addition to the
rights prescribed in this Lease, has all of the rights, titles, liens and
interests in and to Lessee's property, now or hereafter located upon the Leased
Premises, which may be granted a secured party, as that term is defined, under
the Uniform Commercial Code to secure to Lessor payment of all sums due and the
full performance of all Lessee's covenants under this Lease. Lessee will on
request execute and deliver to Lessor a financing statement for the purpose of
perfecting Lessor's security interest under this Lease or Lessor may file this
Lease or a copy thereof as a financing statement. Unless otherwise provided by
law and for the purpose of exercising any right pursuant to this Section, Lessor
and Lessee agree that reasonable notice has been given if such notice is given
by ten days written notice, certified mail, return receipt requested, to Lessor
or Lessee at the addresses specified herein.

     10.03  Landlord's Lien Waiver.  Upon request by Lessee, Lessor will
execute a lien waiver in favor of Lessee's lender in the form prescribed by
Lessee's lender.

                    ARTICLE 11.00   - DEFAULT AND REMEDIES

     11.01  Default by Lessee.  The following are events of default by Lessee
under this Lease:

            A. Lessee fails to pay, within ten (10) days of when due, any
            installment of rent or any other payment required pursuant to this
            Lease, and such failure shall be continuing five (5) days following
            written notice (which notice may include the cancellation notice
            described in Section 11.02(E) hereof) thereof from Lessor to Lessee;
            provided, however, in no event shall Lessee have the right to
            receive or Lessor have the obligation to provide, as a prerequisite
            to an event of default, more than two (2) written notices within any
            twelve (12) month period;

            B. Lessee fails to comply with any term, provision or covenant of
            this Lease, other than the payment of rent and fails to cure the
            failure within thirty (30) days of receipt of written notice (which
            notice may include the cancellation notice described in Section
            11.02(E) hereof) from Lessor;

            C. Lessee or any guarantor of Lessee's obligations hereunder files a
            petition or is adjudged bankrupt or insolvent under any applicable
            federal or state bankruptcy or insolvency law, or admits that it
            cannot meet its financial obligations as they become due; or a
            receiver or trustee is appointed for all or substantially all of the
            assets of Lessee or such guarantor; or Lessee or any guarantor of
            Lessee's

Commercial Lease - Page 23 of 44
<PAGE>

             obligations hereunder makes a transfer in fraud of creditors or
             makes an assignment for the benefit of creditors; or

             D. Lessee does or permits to be done any act which results in a
             lien being filed against the Leased Premises or the Building and
             Lessee fails to contest the lien diligently and in good faith or
             does not prevail, within sixty (60) days of the date the lien is
             filed, in its efforts to remove the lien.

      11.02  Remedies for Lessee's Default.  Upon the occurrence of any event
of default set forth in this Lease, Lessor is entitled to pursue any one or more
of the remedies set forth herein without any notice or demand.

             A. Without declaring the Lease terminated, Lessor may enter upon
             and take possession of the Leased Premises, by picking or changing
             locks if necessary, and lock out, expel or remove Lessee and any
             other person who may be occupying all or any part of the Leased
             Premises without being liable for any claim for damages, and relet
             the Leased Premises on behalf of Lessee and receive the rent
             directly by reason of the reletting; provided however, that Lessor
             has no obligation to relet the Leased Premises so as to mitigate
             the amount for which Lessee is liable. Lessee agrees to pay Lessor
             on demand any deficiency that may arise by reason of any reletting
             of the Leased Premises; further, Lessee agrees to reimburse Lessor
             for any reasonably expenditures made by it in order to relet the
             Leased Premises, including, but not limited to, leasing
             commissions, lease incentives, remodeling and repair costs.

             B. Without declaring the Lease terminated, Lessor may enter upon
             the Leased Premises, by picking or changing locks if necessary,
             without being liable for any claim for damages, except for damages
             arising from Lessor's negligence, recklessness or willful
             misconduct, and do whatever Lessee is obligated to do under the
             terms of this Lease. Lessee agrees to reimburse Lessor on demand
             for any expenses which Lessor may incur in effecting compliance
             with Lessee's obligations under this Lease.

             C. Lessor may terminate this Lease, in which event Lessee shall
             immediately surrender the Leased Premises to Lessor, and if Lessee
             fails to surrender the Leased Premises, Lessor may, without
             prejudice to any other remedy which it may have for possession or
             arrearages in rent, enter upon and take possession of the Leased
             Premises, by picking or changing locks if necessary, and lock out,
             expel or remove Lessee and any other person who may be occupying
             all or any part of the Leased Premises without being liable for any
             claim for damages. Lessee agrees to pay on demand the amount of all
             loss and damage which Lessor may suffer by reason of the
             termination of this Lease under this Section, including without
             limitation, loss and damage due to the failure of Lessee to
             maintain and or repair the Leased Premises as required hereunder
             and/or due to the inability to relet the Leased Premises on terms
             satisfactory to Lessor or otherwise, and any reasonable
             expenditures made by Lessor in order to relet the Leased Premises,

Commercial Lease - Page 24 of 44
<PAGE>

             including, but not limited to, leasing commissions, lease
             incentives, and remodeling and repair costs; provided however, that
             Lessor will have no obligation to relet the Leased Premises so as
             to mitigate the amount for which Lessee is liable. In addition,
             upon termination Lessor may collect from Lessee the value of all
             future rentals required to be paid under this Lease from the date
             Lessor terminates the Lease until the original termination date in
             accordance with applicable law less amounts collected as rent by
             Lessor if the Leased Premises are re-let. Notwithstanding anything
             contained in this Lease to the contrary, this Lease may be
             terminated under this section by Lessor only by mailing or
             delivering written notice of such termination to Lessee, and no
             other act or omission of Lessor constitutes a termination of this
             Lease.

             D. In the event that Lessor exercises its remedy to lock out Lessee
             in accordance with any provision of this Lease, Lessee agrees that
             no notice is required to be posted by Lessor on any door to the
             Leased Premises (or elsewhere) disclosing the reason for such
             action or any other information, and that Lessor is not obligated
             to provide a key to the changed lock to Lessee unless Lessee has
             first:

                1.  brought current all payments due to Lessor under this Lease
                    (unless Lessor has terminated this Lease, in which event
                    payment of all past due amounts do not obligate Lessor to
                    provide a key);

                2.  fully cured and remedied to Lessor's reasonable satisfaction
                    all other defaults of Lessee under this Lease (unless Lessee
                    has abandoned or vacated the Leased Premises, in which event
                    Lessor is not obligated to provide the new key to Lessee
                    under any circumstances); and

                3.  provided Lessor with additional security deposit and
                    assurances reasonably satisfactory to Lessor that Lessee
                    intends to and is able to meet and comply with its future
                    obligations under this Lease, both monetary and nonmonetary.
                    Lessor may, upon written request by Lessee, at Lessor's
                    convenience, upon receipt by Lessor of an amount necessary
                    to reimburse itself for time and expense in providing such
                    service, and upon Lessee's execution and delivery of such
                    waivers and indemnities as Lessor may require at Lessor's
                    option either:

                    a. escort Lessee or its specifically authorized employees or
                    agents to the Leased Premises to retrieve personal
                    belongings of Lessee's employees and property of Lessee that
                    is not subject to a Security Interest provided in this
                    Lease; or

                    b. obtain from Lessee a list of such property and arrange
                    for such items to be removed from the Leased Premises and
                    made available to Lessee at such place at such time as
                    Lessor may designate, provided however, that if Lessor
                    elects option (ii), then Lessee shall pay Lessor in cash in
                    advance, the estimated costs that Lessor may incur upon
                    moving and storage

Commercial Lease - Page 25 of 44
<PAGE>

                  charges theretofore incurred by Lessor with respect to such
                  property. THE PROVISIONS OF THIS ARTICLE ARE INTENDED TO
                  OVERRIDE AND SUPERSEDE ANY CONFLICTING PROVISIONS OF THE TEXAS
                  PROPERTY CODE AND ANY AMENDMENTS OR SUCCESSOR STATUTES
                  THERETO, AND OF ANY OTHER LAW, TO THE MAXIMUM EXTENT PERMITTED
                  BY THE LAW.

          E. Notwithstanding any other remedy set forth in this Lease, if Lessor
          has made rent concessions of any type or character, or waived any base
          rent (i.e. given free rent), and Lessee fails to take possession of
          the Leased Premises on the Commencement Date or there occurs a Lessee
          event of default at any time during the term of this Lease, the rent
          concessions, including any waived base rent, are canceled and the
          amount of the base rent or other rent concessions are due and payable
          immediately as if no rent concessions or waiver of any base rent had
          ever been granted; provided, however, in the event of a default under
          11.01(A) or 11.02(B) hereof, that in order for such cancellation of
          rent concessions to be effective, Lessor must give Lessee express
          notice of the free rent cancellation in the written notice described
          in Section 11.01(A) and 11.01(B). A rent concession or waiver of the
          base rent will not relieve Lessee of any obligation to pay any other
          charge due and payable under this Lease including without limitation
          any sums due under Section 2.02 herein.

          F. If Lessor exercises any of its rights provided in this Article 11
          and Lessee subsequently cures such default, Lessor is entitled to
          receive a service charge of $500.00 from Lessee for its time and
          expense, in addition to any other amounts owed hereunder, prior to
          allowing the Lessee to reenter and reoccupy the Leased Premises.

          G. Lessee hereby expressly waives any and all rights of redemption
          granted by or under any present or future laws in the event of Lessee
          being evicted or dispossessed for any cause, or in the event of Lessor
          obtaining possession of the Leased Premises by reason of the violation
          by Lessee of any of the covenants and conditions of this Lease or
          otherwise. The rights given to Lessor herein are in addition to any
          rights that may be given to Lessor by any statute or otherwise.

          H. Lessor's pursuit of any remedy specified in this Lease will not
          constitute an election to pursue that remedy only, nor preclude Lessor
          from pursuing any other remedy available at law or in equity, nor
          constitute a forfeiture or waiver of any rent or other amount due to
          Lessor as described herein.

          I. If Lessee or any guarantor of Lessee's obligations hereunder is the
          subject of any insolvency, bankruptcy, receivership, dissolution,
          reorganization or similar proceeding, federal or state, voluntary or
          involuntary, under any present or future law or act, Lessor is
          entitled to the automatic and absolute lifting of any automatic stay
          as to the enforcement of its remedies under this Lease, including
          specifically the stay imposed by Section 362 of the United States
          Federal Bankruptcy Code, as

Commercial Lease - Page 26 of 44
<PAGE>

            amended. Lessee hereby consents to the immediate lifting of any
            such automatic stay, and may not contest any motion by Lessor to
            lift such stay. Lessee expressly acknowledges that the Leased
            Premises is not now and will never be necessary to any plan or
            reorganization of any type.

     11.03  Lessor's Liability.  The liability of Lessor to Lessee for any
default by Lessor under the terms of this Lease is limited to Lessee's actual
direct, but not consequential, damages therefor and is recoverable only from the
interest of Lessor in the Building, and Lessor is not personally liable for any
deficiency.

                         ARTICLE 12.00   - DEFINITIONS

     12.01  Abandon.  "Abandon" means the vacating of all or a substantial
portion of the Leased Premises by Lessee or any approved sublessee, whether or
not Lessee or any approved sublessee is in default of the rental payments due
under this Lease.

     12.02  Building.  "Building" as used in this Lease means the building
described in Section 1.02, including the Leased Premises and the land upon which
the Building is situated.

     12.03  Commencement Date.  "Commencement Date" is the date set forth in
Section 1.03. The Commencement Date constitutes the commencement of the term of
this Lease for all purposes, whether or not Lessee has actually taken
possession.

                        ARTICLE 13.00   - MISCELLANEOUS

     13.01  Waiver.  Failure of Lessor to declare an event of default
immediately upon its occurrence, or delay in taking any action in connection
with an event of default, will not constitute a waiver of the default, but
Lessor has 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 11.00 or Article 12.00 above will not preclude
pursuit of any one or more of the other remedies provided elsewhere in this
Lease or provided at law or in equity, nor will pursuit of any remedy constitute
forfeiture or waiver of any rent or damages accruing to Lessor by reason of the
violation of any of the terms, provisions or covenants of this Lease. Lessee
agrees that failure by Lessor to enforce one or more of the remedies provided
upon an event of default will not constitute a waiver of the default or of any
other violation or breach of any of the terms, provisions and covenants
contained in this Lea se.

     No act or thing done by Lessor or its agents during the Lease Term may be
deemed an acceptance of an attempted surrender of the Leased Premises, and no
agreement to accept a surrender of the Leased Premises will be valid unless made
in writing and signed by Lessor.  No reentry or taking possession of the Leased
Premises by Lessor may be construed as an election on its part to terminate this
Lease, unless a written notice of such intention, signed by Lessor, is given by
Lessor to Lessee. Notwithstanding any such reletting or reentry or taking
possession, Lessor may at any time thereafter elect to terminate this Lease for
a previous event of default.  Lessee and Lessor agree that Lessor's acceptance
of rent following an event of default hereunder will not constitute Lessor's
waiver of such event of default. The failure of Lessor to enforce any

Commercial Lease - Page 27 of 44
<PAGE>

of the Rules and Regulations described in Section 3.03 against Lessee or any
other Lessee in the Building will not constitute a waiver of any such Rules and
Regulations. No waiver of any provision of this Lease is effective unless such
waiver is in writing and signed by Lessor. All rights granted to Lessor in this
Lease are cumulative of every other right or remedy which Lessor may otherwise
have at law or in equity, and the exercise of one or more rights or remedies
does not prejudice or impair the concurrent or subsequent exercise of other
rights or remedies.

     13.02  Act of God. Lessor or Lessee is not required to perform any
covenant or obligation in this Lease, or be liable in damages to the other, so
long as the performance or non-performance of the covenant or obligation is
delayed, caused or prevented by Force Majeure or by the other party.

     13.03  Attorney's Fees. If either party defaults in the performance of any
of the terms, covenants, agreements or conditions contained in this Lease and
the other party places in the hands of an attorney the enforcement of all or any
part of this Lease, the collection of any rent due or to become due or recovery
of the possession of the Leased Premises, agrees to pay the non-defaulting
party's costs of collection, including reasonable attorney's fees for the
services of the attorney, whether suit is actually filed or not.

     13.04  Successors. This Lease is binding upon and inures to the benefit of
Lessor and Lessee and their respective heirs, personal representatives,
successors and assigns. It is hereby covenanted and agreed that should Lessor's
interest in the Leased Premises cease to exist for any reason during the term of
this Lease, then notwithstanding the happening of such event this Lease
nevertheless will remain unimpaired and in full force and effect, and Lessee
hereunder agrees to attorn to the then owner of the Leased Premises.

     13.05  Rent Tax. If applicable in the jurisdiction where the Leased
Premises are situated, Lessee shall pay and be liable for all rental, sales and
use taxes or other similar taxes, if any, levied or imposed by any city, state,
county or other governmental body having authority, such payments to be in
addition to all other payments required to be paid to Lessor by Lessee under the
terms of this Lease. Any such payment must be paid concurrently with the payment
of the rent, additional rent, operating expenses or other charge upon which the
tax is based as set forth above.

     13.06  Captions. The captions appearing in this Lease are inserted only
as a matter of convenience and in no way define, limit, construe or describe the
scope or intent of any Section.

     13.07  Notice. All rent and other payments required to be made by Lessee
must be paid to Lessor at the address set forth in Section 1.05. All payments
required to be made by Lessor to Lessee are payable to Lessee at the address set
forth in Section 1.05 or at any other address within the United States as Lessee
may specify from time to time by written notice. For purposes hereof, any notice

Except as specifically set forth herein, in no event will notice by facsimile
transmission be proper notice under the terms of this Lease.

    13.08 Submission of Lease. Submission of this Lease to Lessee for signature
does not constitute a reservation of space or an option or offer to lease. This
Lease is not deemed effective until execution by and delivery to both Lessor and
Lessee.

    13.09 Representations, Warranties and Covenants of Lessee and Lessor. Lessee
represents, warrants and covenants that it is now in a solvent condition; that

that both parties hereto have participated in the preparation of the final form
of this Lease. Wherever in this Lease provision is made for liquidated damages,
it is because the parties hereto acknowledge and agree that the determination of
actual damages (of which such liquidated damages are in lieu) is speculative and
difficult to determine; the parties agree that liquidated damages herein are not
a penalty.

    13.23 Financial Statements. Lessee acknowledges that it has provided Lessor
with its financial statement(s) as a primary inducement to Lessor's agreement to
lease the Leased Premises to Lessee, and that Lessor has relied on the accuracy
of said financial statement(s) in entering into this Lease. Lessee represents
and warrants that the information contained in said financial statement(s) is
true, complete and correct in all material aspects, and agrees that the
foregoing representations are conditions to all of Lessor's obligations under
this Lease.

    At the request of Lessor (only upon the sale or refinancing of the Building,
or upon any extension or renewal hereof), Lessee shall, not later than thirty
(30) days following such request, furnish to Lessor a financial statement of
Lessee as of the end of the prior fiscal year accompanied by a statement of
income and expense for the year then ended, together with a certificate of the
chief financial officer, owner or partner of Lessee to the effect that the
financial statements have been prepared in conformity with generally accepted
accounting principles consistently applied and fairly present the financial
condition and results of operations of Lessee as of and for the periods covered.

    13.24 Time of Essence. With respect to all required acts of Lessee, time is
 of the essence of this Lease.

    13.25 Joint and Several Liability. If there is more than one Lessee, the
obligations hereunder imposed upon Lessee are joint and several. If there is a
guarantor(s) of Lessee's obligations hereunder, the obligations of Lessee are
joint and several obligations of Lessee and each such guarantor, and Lessor need
not first proceed against Lessee hereunder before proceeding against each such
guarantor, nor will any such guarantor be released from its guarantee for any
reason whatsoever, including, without limitation, any amendment of this Lease,
any forbearance by Lessor or waiver of any of Lessor's rights, the failure to
give Lessee or any such guarantor any notices, or the release of any party
liable for the payment or performance of any of Lessee's obligations hereunder.

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

    13.27 Constructive Eviction. Lessee shall not be entitled to claim a
constructive eviction from the Leased Premises unless Lessee has first notified
Lessor in writing of the condition giving rise thereto, and, if the complaints
are justified, unless Lessor has failed to remedy such conditions with a
reasonable time after receipt of said notice.

Commercial Lease - Page 36 of 44

     condition not meeting this high standard should be reported directly to

                              Lessor Improvements

own cost and expense, construct the Building and improvements (the "Shell
Building Improvements") as generally shown on the site plan and artist's
rendering prepared by Rehler Vaughn & Koone, Inc., and attached hereto as

generally consistent in quality with the building shown in the artist's
rendering attached as Exhibit "A" and with other buildings in Dallas, Texas,
which were shown to Lessee's representatives as samples of Lessor's projects.
The Final Shell Plans and Specifications shall be provided to Lessee on or
before June 1, 1999. Lessor will begin construction of the Shell Building
Improvements no later than June 1, 1999 and shall have completed the Shell
Building Improvements to the extent to allow construction of the Lessee
Improvements no later than September 15, 1999. Except for immaterial field
changes, modifications to the Final Shell Plans and Specifications must be made
and accepted only by written change order or agreement signed by Lessor and
Lessee and will constitute an amendment to this Lease. Lessee shall be
responsible for payment in advance of all work and construction resulting from
changes in the Final Shell Plans and Specifications requested by Lessee. The
Final Shell Plans and Specifications (when approved by Lessor and Lessee) are
incorporated in this Lease by reference. For the purpose of this Section, an
"immaterial field change" shall mean such field changes which are required by
any governmental authority or changes which (i) do not affect the size,
configuration, structural integrity, quality, character, architectural
appearance and standard of workmanship contemplated in the Final Shell Plans and
Specifications, (ii) will not result in any default in any obligation to any
person or violation of any governmental requirements, and (iii) the cost of or
reduction resulting from any single field change or extra does not exceed
$20,000 and the aggregate amount of all such changes and extras does not exceed
$100,000. Lessor agrees to construct the improvements substantially in
accordance with the Final Shell Plans and Specifications, in a good and
workmanlike manner and in full compliance with all provisions of federal, state
and local authorities having jurisdiction over the Leased Premises.

           (a) If (i) this Lease is executed and delivered by Lessee by April
13, 1999, (ii) the Lessee Improvement Final Plans and Specifications are
approved by Lessor by July 15, 1999 (iii) Lessee has selected by September 1,
1999, the contractor who will construct the Lessee Improvements, and (iv) the
building permit for the Lessee Improvements is issued by September 15, 1999,
then Lessor shall cause Substantial Completion (as defined in Section 17.04
hereof) to occur no later than December 15, 1999 (such date being extended by
the longest number of days that the satisfaction of any of the above conditions
is delayed, Force Majeure and Lessee Delays with the date, as extended, being
hereinafter referred to as the "Threshold Date"). In the event that the
foregoing conditions are satisfied and Substantial Completion does not occur by
the Threshold Date, then Lessee, as Lessee's sole and exclusive remedy and
measure of damages for

Commercial Lease - Page 38 of 44
<PAGE>

or related to the delay in Substantial Completion, shall have the right to
receive one day of free rent, in addition to the free rent described in Section
3.01, for each day of unexcused delay beyond the Threshold Date, up to a maximum
of sixty (60) days, and in the event of unexcused delay beyond sixty (60) days
after the Threshold Date, the Lessee shall have the right to receive two (2)
days of free rent, in addition to the free rent described in Section 3.01, for
each day of unexercised delay beyond sixty days after the Threshold Date, and in
the event of unexcused delay beyond one hundred twenty (120) days after the
Threshold Date, the Lessee shall have the right to terminate this Lease by
written notice thereof to Lessor within ten (10) days following the one hundred
twentieth day after such Threshold Date; provided, however, in the event Lessee
fails to deliver such termination notice within such ten (10) day period, the
Lessee shall be deemed to have waived any right to terminate this Lease for
delay provided in this Section.

    17.02  Force Majeure. "Force Majeure" delay shall mean a delay caused by
reason of fire, acts of God, unreasonable delays in transportation, embargo,
weather, strike, other labor disputes, governmental preemption of priorities or
other controls in connection with a national or other public emergency, or
shortages of fuel, supplies or labor or any similar cause not within the
reasonable control of the party claiming the benefits of any Force Majeure
provisions. The party claiming the benefits of any Force Majeure provisions
shall be required (as a condition to the effectiveness thereof) to provide
written notice of the occurrence of such Force Majeure event within ten (10)
days following such occurrence.

    17.03  Lessor and Lessee Delay.

           (a) The terms "Lessor Delays", "Delays caused by Lessor", "Lessee
Delay" or "Delays caused by Lessee" shall mean delay in completion of
construction of the Shell Building Improvements or the Lessee Improvements
caused by:

               (1)  Unless due to the acts or omissions of the other party or
    such party's agents, employees or contractors, the respective party's
    failure to perform its design approval obligations or its construction
    period obligations by the dates or within the time periods shown in the
    Lease or this Addendum 1; and

               (2)  Any subsequent changes, modifications or alterations to the
    final plans and specifications or the Final Tenant Improvement Plans and
    specifications which reasonably cause delay in the completion thereof; and

           (b) "Lessee Delay" or "Delays caused by Lessee" shall also mean
delays due to the scope and extent of the Lessee Improvements to be constructed
by Lessor. For purposes of determining Lessee Delay under this Section, the
Lessor must provide notice to Lessee of the existence of excessive Lessee
Improvements, special design or construction considerations or other matters
which will extend the time necessary for the construction of the Lessee
Improvements beyond two (2) days; such notice to be provided by Lessor to Lessee
together with Lessor's delivery of approval and/or objections to Lessee's plans
and specifications for the Lessee Improvements from time-to-time. Such notice
shall specify the reasons for the delay and the estimated length of delay and,
unless the Lessee's plans and specifications are modified to eliminate such
items, the estimated length of the delay shall be included as a Lessee Delay.
For

Commercial Lease - Page 39 of 44

purposes of determining delay, the terms Lessor and Lessee shall include their
respective contractors, agents and employees. In addition, the party claiming
the benefits of such delay shall be required (as a condition to the
effectiveness thereof) to provide written notice of the occurrence of such delay
within ten (10) days following such occurrence.

    17.04 "Substantial Completion" shall mean that time when the following
conditions are satisfied:

          (a) Lessor secures and delivers to Lessee the required temporary or
permanent certificate of occupancy, final inspection report or the substantial
equivalent under applicable state or local law relative to the Shell Building
Improvements and the Lessee Improvements; and

          (b) The construction is completed in accordance with the Final Shell
Plans and Specifications and the Lessee Improvements Final Plans and
Specifications as acknowledged by Lessor's architect in writing to Lessee,
