                                     LEASE
                                     -----

     THIS LEASE AGREEMENT (this "Lease") is entered into as of August __, 1997,
between WHLC REAL ESTATE LIMITED PARTNERSHIP, a Delaware limited partnership
("Landlord"), and H.D. VEST, INC., a Texas corporation ("Tenant").

     1.   Lease Grant. Subject to the terms of this Lease, Landlord leases to
Tenant, and Tenant leases from Landlord, the fourth (4th), fifth (5th), and
sixth (6th) floors (the "Premises") as depicted in the plan attached as Exhibit
A in the office building (the "Building") located at 6333  N. State Highway 161,
Irving, Texas 75219, known as Las Colinas Corporate Center - Phase I. The land
on which the Building is located is described on Exhibit B. The term "Building"
includes the related land, driveways, parking facilities, and similar
improvements.

     2.   Term. The term of this Lease shall be 120 months, commencing (subject
to the provisions of Exhibit D) on January 1, 1998 (the "Commencement Date"),
and expiring at 5:00 p.m., December 31, 2007 (the "Term", which definition
shall include all effective renewals of the initial Term). Exhibit D to this
Lease delineates Landlord's and Tenant's respective responsibilities regarding
delivery of the Premises to Tenant, and provides for adjustment of the
Commencement Date in certain instances and for certain remedial rights if
Landlord is delayed in so delivering the Premises.

     3.   Rent.

          (a)  Basic Rent. "Basic Rent" (herein so called) shall be the
following amounts for the following periods of time:

          Time Period         Monthly Basic Rent

            Month 1              No Basic Rent

            Month 2                $94,468.00

          Months 3-24             $138,165.00

          Months 25-48            $148,153.00

          Months 49-84            $154,812.00

          Months 85-120           $158,141.00

          (b)  Payment. Tenant shall timely pay to Landlord Basic Rent and all
additional sums to be paid by Tenant to Landlord under this Lease (collectively,
the "Rent"), without deduction or set off except as herein expressly provided,
at Landlord's address provided for in this Lease or as otherwise specified by
Landlord. Basic Rent, adjusted as herein provided, shall be payable monthly in
advance, and shall be accompanied by all applicable state and local sales or
use taxes. The second

                                       1
<PAGE>

monthly installment of Basic Rent shall be payable contemporaneously with the
execution of this Lease; thereafter, Basic Rent shall be payable on the first
day of each month beginning on the first day of the third full calendar month of
the Term. The monthly Basic Rent for any partial month at the beginning of the
Term shall equal the product of 1/365 of the annual Basic Rent in effect during
the partial month and the number of days in the partial month from and after the
Commencement Date, and shall be due on the Commencement Date.

          (c)  [Intentionally omitted].

          (d)  Operating Costs.

               (1)  Tenant shall pay an amount (per each rentable square foot in
     the Premises) ("Additional Rent") equal to the difference between the
     Operating Costs (defined below) per rentable square foot in the Building
     and the actual Operating Costs for the calendar year 1998 (the "Expense
     Stop"); provided, that any increase in Additional Rent attributable to
     Controllable Costs (hereafter defined) for any calendar year of the Lease
     shall not exceed 8% of the Controllable Costs for the previous calendar
     year. As used herein, the term "Controllable Costs" shall mean all
     Operating Costs except for costs related to insurance and costs related to
     provision of utility services. Landlord may collect such amount in a lump
     sum, which shall be due within 30 days after Landlord furnishes to Tenant
     the Operating Costs and Tax Statement (defined below). Alternatively,
     Landlord may make a good faith estimate of the Additional Rent to be due by
     Tenant for any calendar year or part thereof during the Term, and Tenant
     shall pay to Landlord, on the Commencement Date and on the first day of
     each calendar month thereafter, an amount equal to the estimated Additional
     Rent for such calendar year or part thereof divided by the number of months
     therein. From time to time, Landlord may estimate and re-estimate the
     Additional Rent to be due by Tenant and deliver a copy of the estimate or
     re-estimate to Tenant. Thereafter, the monthly installments of Additional
     Rent payable by Tenant shall be appropriately adjusted in accordance with
     the estimations so that, by the end of the calendar year in question,
     Tenant shall have paid all of the Additional Rent as estimated by Landlord.
     Any amounts paid based on such an estimate shall be subject to adjustment
     as herein provided when actual Operating Costs are available for each
     calendar year.

               (2)  The term "Operating Costs" shall mean all expenses and
     disbursements (subject to the limitations set forth below) that Landlord
     incurs in connection with the ownership, operation, and maintenance of the
     Building, determined in accordance with sound accounting principles
     consistently applied, including, but not limited to, the following costs:
     (A) reasonable wages and salaries (including management fees) of all
     employees engaged in the operation, maintenance, and security of the
     Building, including taxes, insurance and benefits relating thereto; (B) all
     supplies and materials used in the operation, maintenance, repair,
     replacement, and security of the Building; (C) costs for improvements made
     to the Building which, although capital in nature, are expected to reduce
     the normal operating costs of the Building, as well as capital improvements
     made in order to comply with any law hereafter promulgated by any
     governmental authority, as amortized over the useful economic life of such
     improvements as determined by Landlord in its

                                       2
<PAGE>

     reasonable discretion; (D) cost of all utilities, except the cost of
     utilities reimbursable to Landlord by the Building's tenants other than
     pursuant to a provision similar to this Section 3.(d); (E) insurance
     expenses; (F) repairs, replacements, and general maintenance of the
     Building; and (G) service or maintenance contracts with independent
     contractors for the operation, maintenance, repair, replacement, or
     security of the Building (including, without limitation, alarm service,
     window cleaning, and elevator maintenance). Landlord shall use commercially
     reasonable efforts to minimize Operating Costs in a manner consistent with
     good business practices, and there shall be no duplication in charges to
     Tenant.

          Operating Costs shall not include costs for (i) capital improvements
     made to the Building, other than capital improvements described in Section
     3.(d)(2)(C) and except for items which are generally considered maintenance
     and repair items, such as painting of common areas, replacement of carpet
     in elevator lobbies, and the like; (ii) repair, replacements and general
     maintenance paid by proceeds of insurance or by Tenant or other third
     parties; (iii) interest, amortization or other payments on loans to
     Landlord; (iv) depreciation; (v) leasing commissions; (vi) legal expenses
     for services, including legal fees to settle disputes with other tenants,
     other than those that benefit the Building tenants generally (e.g., tax
     disputes); (vii) renovating or otherwise improving (including painting,
     decorating or redecorating) space for other occupants of the Building or
     vacant space in the Building or any other costs directly related to
     procuring new leases or renewals, expansions or extensions of existing
     leases; (viii) Taxes (defined below), (ix) federal income taxes imposed on
     or measured by the income of Landlord from the operation of the Building,
     (x) any taxes levied or assessed against the personal property of any other
     tenant, (xi) rental concessions or lease buy-outs; (xii) brokerage, legal
     and professional fees expended by Landlord in connection with negotiating
     and entering into any leases and any related instruments (including without
     limitation guaranties, surrender agreements, leasing amendments and
     consents to assignment or subletting) with any other third party leases
     other than Tenant or a Tenant Party or other occupant of any portion of the
     Building, and the enforcement of any such instruments relating to any other
     third party leases other than Tenant or a Tenant Party; (xiii) any costs,
     fines or penalties incurred due to intentional violations by Landlord of
     any law or applicable regulations; (xiv) correcting any construction or
     design defects in the Building; (xv) the replacement of any item covered
     under warranty to the extent of proceeds or payments actually received by
     Landlord under such warranty; (xvi) work or service performed on any
     facility other than the Building or the Premises or on any common area that
     serves the Building or the Premises and any other building or premises,
     provided that the charge for any such work or services for such common area
     shall be allocated equitably among the buildings served thereby and any
     charge so allocated to the Building shall be included in Operating Costs;
     and (xvii) a violation or claimed violation by Landlord or any other tenant
     or occupant of the terms and conditions of any lease or other rental
     arrangement covering space in the Building (or any portion thereof).

               (3)  Tenant shall also pay its Proportionate Share (defined
     below) of any increase in Taxes for each year and partial year falling
     within the Term, which shall be determined by multiplying the difference
     between (A) the Taxes for the year in question and (B) $487,146.00 by
     Tenant's Proportionate Share. Tenant shall pay its Proportionate Share

                                       3
<PAGE>

     of Taxes in the same manner as provided above for Additional Rent with
     regard to Operating Costs. "Taxes" shall mean taxes, assessments, and
     governmental charges whether federal, state, county or municipal, and
     whether they be by taxing districts or authorities presently taxing or by
     others, subsequently created or otherwise, and any other taxes and
     assessments attributable to the Building (or its operation), excluding,
     however, penalties and interest thereon and federal and state taxes on
     income (if the present method of taxation changes so that in lieu of the
     whole or any part of any Taxes, there is levied on Landlord a capital tax
     directly on the rents received therefrom or a franchise tax, assessment, or
     charge based, in whole or in part, upon such rents for the Building, then
     all such taxes, assessments, or charges, or the part thereof so based,
     shall be deemed to be included within the term "Taxes" for purposes
     hereof). Taxes shall include the reasonable costs of consultants and
     appraisers retained in an effort to lower taxes and all reasonable costs
     incurred in disputing any taxes or in seeking to lower the tax valuation of
     the Building.

               (4)  By April 1 of each calendar year, or as soon thereafter as
     practicable, Landlord shall furnish to Tenant a statement of Operating
     Costs for the previous year, adjusted as provided in Section 3.(d)(6), and
     of the Taxes for the previous year (the "Operating Costs and Tax
     Statement"). If the Operating Costs and Tax Statement reveals that Tenant
     paid more for Operating Costs than the actual amount for the year for which
     such statement was prepared, or more than its actual share of Taxes for
     such year, then Landlord shall promptly credit or reimburse Tenant for such
     excess; likewise, if Tenant paid less than Tenant's actual Proportionate
     Share of Additional Rent or share of Taxes due, then Tenant shall promptly
     pay Landlord such deficiency.

               (5)  As used herein, Tenant's "Proportionate Share" shall be
     51.37%, which is the percentage obtained by dividing the rentable square
     feet of area in the Premises, which is stipulated to be 80,721 rentable
     square feet, by the total number of square feet of area in the Building,
     which is stipulated to be 157,144 rentable square feet. If either party so
     requests, the area of the Premises or the Building shall be remeasured, at
     the requesting party's cost, by an engineer or architect reasonably
     satisfactory to both parties using the American National Standard Method
     for measuring floor area in office buildings ANSI/BOMA Z65.1-1996 (the
     "BOMA Method"). The area stipulated herein shall be fully applicable and
     binding on the parties until after such time, if ever, as any such
     measurement is effected, following which event the new measurements, if
     they differ by more than three percent (3%) from those herein set forth,
     shall be applicable to future obligations only. Either party must make its
     request regarding remeasurement not later than 60 days after the
     Commencement Date, and thereafter neither party shall have any further
     right to so remeasure either the Premises or the Building.

               (6)  With respect to any calendar year or partial calendar year
     in which the Building is not occupied to the extent of 95% of the rentable
     area thereof, the Operating Costs for such period shall, for the purposes
     hereof, be increased to the amount which would have been incurred had the
     Building been occupied to the extent of 95% of the rentable area thereof.

                                       4

          (e)  Tenant Inspection Right. After giving Landlord 30-days' prior
written notice thereof, Tenant may inspect or audit Landlord's records relating
to Operating Costs for any periods of time within one year before the audit or
inspection; however, no audit or inspection shall extend to periods of time
before the Commencement Date. If Tenant fails to object to the calculation of
Operating Costs on an annual Operating Costs and Tax Statement within 180 days
after the statement has been delivered to Tenant, then Tenant shall have waived
its right to object to the calculation of Operating Costs for the year in
question and the calculation of Operating Costs set forth on such statement
shall be final. Tenant's audit or inspection shall be conducted during business
hours reasonably designated by Landlord. Tenant shall pay the reasonable out-of-
pocket cost paid to third parties of such audit or inspection, unless the total
Operating Costs charged to Tenant for the time period in question is determined
to be in error by more than 5% in the aggregate, and, as a result thereof,
Tenant paid to Landlord $5,000 more than the actual Operating Costs due for such
time period, in which case Landlord shall pay the audit cost. Tenant may not
conduct an inspection or have an audit performed more than once during any
calendar year. If such inspection or audit reveals that an error was made in the
Operating Costs previously charged to Tenant, then Landlord shall refund to
Tenant any overpayment of any such costs, or Tenant shall pay to Landlord any
underpayment of any such costs, as the case may be, within 30 days after
notification thereof. Provided Landlord's accounting for Operating Costs is
consistent with the terms of this Agreement, Landlord's good faith judgment
regarding the proper interpretation of this Agreement and the proper accounting
for Operating Costs shall be binding on Tenant in connection with any such audit
or inspection. Tenant shall maintain the results of each such audit or
inspection confidential and shall not be permitted to use any third party to
perform such audit or inspection, other than an independent firm of certified
public accountants (1) reasonably acceptable to Landlord, and (2) which agrees
with Landlord in writing to maintain the results of such audit or inspection
confidential. Further, if Tenant agrees to compensate any such third party on a
contingency fee basis or in any other manner which is dependent upon the results
of the audit or inspection, then Landlord's obligation shall be limited to
refunding any erroneous overpayment of Operating Costs by Tenant, and Landlord
shall not be obligated to reimburse Tenant for any fees or other costs incurred
in connection with such audit or inspection.

     4.   Delinquent Payment; Handling Charges. All past due payments required
of Tenant hereunder shall bear interest from the date due until paid at the
lesser of 12% per annum (the "Interest Rate") or the maximum lawful rate of
interest; additionally, after Landlord has delivered to Tenant written notice of
its failure to pay Rent when due pursuant to Section 16.(a), then Landlord may,
without delivering to Tenant notice of such delinquency, charge Tenant a fee
equal to 5% of any future delinquent payment during the 12-month period
following such delinquency to reimburse Landlord for its cost and inconvenience
incurred as a consequence of Tenant's delinquency. In no event, however, shall
the charges permitted under this Section 4 or elsewhere in this Lease, to the
extent they are considered to be interest under law, exceed the maximum lawful
rate of interest.

     5.   Security Deposit. Contemporaneously with the execution of this Lease,
Tenant shall pay to Landlord $138,165.00 (the "Security Deposit"), which shall
be held by Landlord to secure Tenant's performance of its obligations under this
Lease. The Security Deposit is not an advance payment of Rent or a measure or
limit of Landlord's damages upon an Event of Default (defined in Section 16).
Landlord may, from time to time and without prejudice to any other remedy, use
all or

                                       5
<PAGE>

a part of the Security Deposit to perform any obligation Tenant fails to perform
hereunder. Following any such application of the Security Deposit, Tenant shall
pay to Landlord on demand the amount so applied in order to restore the Security
Deposit to its original amount. Provided that Tenant has performed all of its
obligations hereunder, Landlord shall, within 30 days after the Term ends,
return to Tenant the portion of the Security Deposit which was not applied to
satisfy Tenant's obligations. The Security deposit may be commingled with other
funds, and no interest shall be paid thereon. If Landlord transfers its interest
in the Premises and the transferee assumes Landlord's obligations under this
Lease, then Landlord may, upon written notice to Tenant, assign the Security
Deposit to the transferee and Landlord thereafter shall have no further
liability for the return of the Security Deposit.

     6.   Landlord's Obligations.

          (a)  Services. Landlord shall furnish to Tenant (1) water at those
points of supply provided for general use of tenants of the Building; (2) heated
and refrigerated air conditioning as appropriate, at such temperatures and in
such amounts as are standard for the Comparable Buildings (defined below); (3)
janitorial service to the Premises on weekdays, other than holidays, for
Building-standard installations in accordance with Schedule 6(a), provided that
Landlord shall have no obligation to furnish janitorial services to any No
Access Rooms (as defined in Exhibit C) and such window washing as may from time
to time be reasonably required; (4) elevators for ingress and egress to the
floor on which the Premises are located, in common with other tenants, provided
that Landlord may reasonably limit the number of operating elevators during non-
business hours and holidays (but Tenant shall have access to the Building and
the Premises 24 hours a day, 7 days a week, 52 weeks per year); (5) electrical
current during normal business hours for equipment that does not require more
than 110 volts and whose electrical energy consumption does not exceed normal
office usage and replacement of Building-standard lamps and ballasts; and (6) a
multi-function card-key building access system to the Premises, Building, and
common area entrances, and on-call access to uniform guard service, which
service shall be accessible during business and evening hours following the
Commencement Date (provided however, that Landlord shall not be liable in
damages (whether under theories of strict liability, tort or otherwise) to
Tenant or any assignee or sublessee for failure to provide any security service
in respect of the Premises or the Building, Tenant's sole remedy in case of
failure to provide such service being to enforce specific performance of
Landlord's obligations). If Tenant has any reasonable objection to the security
service provided by Landlord, it may notify Landlord thereof, specifying in
detail the reasons for its dissatisfaction. Following receipt of such notice,
Landlord shall have 30 days to consult with its service provider in an effort to
rectify the sources of Tenant's dissatisfaction. If following such 30-day period
Tenant is still dissatisfied with the security service provided by Landlord, it
may so notify Landlord and Landlord shall then have 30 days to provide an
alternate security service provider reasonably satisfactory to Tenant. Landlord
shall maintain the common areas of the Building in reasonably good order and
condition, except for damage caused by a Tenant Party. If Tenant desires any of
the services specified in Section 6.(a)(2) at any time other than (A) between
7:00 a.m. and 7:00 p.m. on weekdays, (B) between 8:00 a.m. and 1:00 p.m. on
Saturday, or (C) on Sunday or holidays, then such services shall be supplied to
Tenant upon the written request (or verbal request followed by written
confirmation within 24 hours of the next business day) of Tenant delivered to
Landlord before 3:00 p.m. on the business day preceding such extra usage, and
Tenant

                                       6
<PAGE>

shall pay to Landlord the cost of such services within ten days after Landlord
has delivered to Tenant an invoice therefor. The costs incurred by Landlord in
providing after-hour HVAC service to Tenant shall include costs for electricity,
water, sewage, water treatment, labor, metering, filtering, and maintenance
reasonably allocated by Landlord to providing such service. Upon request,
Landlord shall provide for janitorial services in excess of or in addition to
those required under Section 6.(a)(3), provided that Tenant shall pay all costs
incurred in providing such extra or additional services within ten days after
Landlord has delivered to Tenant an invoice therefor. For the purposes of this
Section 6.(a), the term "holidays" shall mean New Years Day, Memorial Day,
Independence Day, Labor Day, Thanksgiving Day, the Friday following Thanksgiving
Day, and Christmas Day. At such time, if ever, as Landlord completes development
of office building improvements on the property adjoining the Building and a
majority of the space in such improvements is occupied, then so long as Landlord
or any Affiliate of Landlord owns both the Building and such other office
building Landlord shall provide on-site uniform guard service therefor during
evening hours as determined by Landlord, which services shall be provided under
the same terms and conditions (and subject to the same limitations on liability)
as provided in Section 6.(a)(6).

          (b)  Excess Utility Use. Landlord shall not be required to furnish
electrical current for equipment that requires more than 110 volts or other
equipment whose electrical energy consumption exceeds normal office usage. If
Tenant's requirements for or consumption of electricity exceed the electricity
to be provided by Landlord as described in Section 6(a), Landlord shall, at
Tenant's expense, make reasonable efforts to supply such service through the
then-existing feeders and risers serving the Building and the Premises, and
Tenant shall pay to Landlord the cost of such service within ten days after
Landlord has delivered to Tenant an invoice therefor. Landlord may determine the
amount of such additional consumption and potential consumption by any
verifiable method, including installation of a separate meter in the Premises
installed, maintained, and read by Landlord, at Tenant's expense. Tenant shall
not install any electrical equipment requiring special wiring or requiring
voltage in excess of 110 volts or otherwise exceeding Building capacity unless
approved, which approval shall not be unreasonably withheld or delayed, in
advance by Landlord. The use of electricity in the Premises shall not exceed the
capacity of existing feeders and risers to or wiring in the Premises. Any risers
or wiring required to meet Tenant's excess electrical requirements shall, upon
Tenant's written request, be installed by Landlord, at Tenant's cost, if, in
Landlord's judgment, which judgment shall not be unreasonably withheld or
delayed, the same are necessary and shall not cause permanent damage to the
Building or the Premises, cause or create a dangerous or hazardous condition,
entail excessive or unreasonable alterations, repairs, or expenses, or interfere
with or disturb other tenants of the Building. If Tenant uses machines or
equipment in the Premises which affect the temperature otherwise maintained by
the air conditioning system or otherwise overload any utility, Landlord may
require Tenant to (or Tenant in its sole discretion may), at Tenant's sole cost
and expense, install supplemental air conditioning units or other supplemental
equipment in the Premises in accordance with Section 7, such installation to
commence within thirty (30) days after Tenant receives notice from Landlord and
to be diligently and continuously pursued to completion thereafter, and the cost
of operation, use, and maintenance thereof shall be paid by Tenant to Landlord
within thirty (30) days after Landlord has delivered to Tenant an invoice
therefor.

                                       7
<PAGE>

          (c)  Restoration of Services; Abatement. Landlord shall use reasonable
efforts to restore any service, including utility services, required of it that
becomes unavailable; however, such unavailability shall not render Landlord
liable for any damages caused thereby, be a constructive eviction of Tenant,
constitute a breach of any implied warranty, or, except as provided in the next
sentence, entitle Tenant to any abatement of Tenant's obligations hereunder. If,
however, Tenant is prevented from using the Premises for more than six
consecutive business days because of the unavailability of any such service and
such unavailability was not caused by a Tenant Party, then Tenant shall, as its
exclusive remedy, be entitled to a reasonable abatement of Rent for each
consecutive day (after such six-day period) that Tenant is so prevented from
using the Premises.

     7.   Improvements; Alterations; Repairs; Maintenance.

          (a)  Improvements; Alterations. Following completion of Tenant's
initial improvements, improvements to the Premises shall be installed at
Tenant's expense only in accordance with plans and specifications which have
been previously submitted to and approved, which approval shall not be
unreasonably withheld or delayed, in writing by Landlord. Except for cosmetic,
non-structural alterations, additions or improvements with a cost of $5,000.00
or less, no alterations or physical additions in or to the Premises may be made
without Landlord's prior written consent, which shall not be unreasonably
withheld or delayed; however, Landlord may withhold its consent to any
alteration or addition that would affect the Building's structure or its HVAC,
plumbing, electrical, or mechanical systems. Except for cosmetic, non-structural
alterations, additions or improvements that are not readily visible from the
exterior of the Building or to other tenants of the Building with a cost
of $5,000.00 or less, Tenant shall not paint or install lighting or decorations,
signs, window or door lettering, or advertising media of any type on or about
the Premises without the prior written consent of Landlord, which shall not be
unreasonably withheld or delayed; however, Landlord may withhold its consent to
any such painting or installation which would affect the appearance of the
exterior of the Building or of any common areas of the Building. All
alterations, additions, or improvements made in or upon the Premises shall, at
Landlord's option, either be removed by Tenant prior to the end of the Term (and
Tenant shall repair all damage caused thereby), or shall remain on the Premises
at the end of the Term without compensation to Tenant, provided that (1) at the
time Tenant obtains Landlord's approval of plans and specifications for any
alterations, additions, or improvements, Landlord shall, if Tenant so requests,
specify whether the same shall be so removed or shall remain on the Premises,
(2) Tenant shall not be required to remove any cabling installed as a part of
construction of Tenant's initial improvements in the Premises as specified in
Exhibit D, and (3) Tenant may remove from the Premises the items specified in
Section 20. All alterations, additions, and improvements shall be constructed,
maintained, and used by Tenant, at its risk and expense, in accordance with all
Laws; Landlord's approval of the plans and specifications therefor shall not be
a representation by Landlord that such alterations, additions, or improvements
comply with any Law.

                                       8
<PAGE>

          (b)  Repairs; Maintenance.

               (1)  Landlord's Obligations. Landlord shall maintain the common
     areas of the Building and the Building systems in a manner consistent with
     other mid-rise (i.e., having three to twelve stories) multi-tenant
     commercial office buildings comparable to the Building in size, design,
     quality, use and tenant mix located in the Las Colinas area north of
     Gateway Drive, east of Beltline Road, west of O'Connor Boulevard and south
     of Interstate Highway 635 ("Comparable Buildings"), including the
     structural components of the Building, card access system, landscaping,
     snow and ice removal (when required) and, subject to Section 14, repairs
     necessitated because of casualty (other than casualties caused by Tenant).

               (2)  Tenant's Obligations. Tenant shall maintain the Premises in
     a clean, safe, and operable condition, and shall not permit or allow to
     remain any waste or damage to any portion of the Premises. Tenant shall
     repair or replace, subject to Landlord's reasonable direction and
     supervision, any damage to the Building caused by a Tenant Party. If Tenant
     fails to make such repairs or replacements within 15 days after Tenant's
     receipt of Landlord's written notice for Tenant to make such repair or
     replacement, then Landlord may make the same at Tenant's cost. If any such
     damage occurs outside of the Premises, then Landlord may elect to repair
     such damage at Tenant's expense, rather than having Tenant repair such
     damage. The cost of all reasonable repair or replacement work performed by
     Landlord under this Section 7 shall be paid by Tenant to Landlord within
     thirty (30) days after Landlord has invoiced Tenant therefor.

          (c)  Performance of Work. All work described in this Section 7 shall
be performed only by Landlord or by contractors and subcontractors approved,
which approval shall not be unreasonably withheld or delayed, in writing by and
reasonably satisfactory to Landlord. Tenant shall cause all contractors and
subcontractors to procure and maintain insurance coverage naming Landlord as an
additional insured against such risks, in such amounts, and with such companies
as Landlord may reasonably require. All such work shall be performed in
accordance with all Laws and in a good and workmanlike manner so as not to
damage the Premises, the Building, or the components thereof.

          (d)  Mechanic's Liens. Tenant shall not permit any mechanic's liens to
be filed against the Premises or the Building for any work performed, materials
furnished, or obligation incurred by or at the request of Tenant. If such a lien
is filed, then Tenant shall, within 45 days after Landlord has delivered notice
of the filing thereof to Tenant, either pay the amount of the lien or diligently
contest such lien and deliver to Landlord a bond or other security reasonably
satisfactory to Landlord. If Tenant fails to timely take either such action,
then Landlord may pay the lien claim, and any reasonable amounts so paid,
including reasonable expenses and interest, shall be paid by Tenant to Landlord
within 30 days after Landlord has invoiced Tenant therefor.

     8.   Use. Tenant shall continuously occupy and use the Premises only for
general office purposes (the "Permitted Use") and shall comply with all Laws
relating to the use, condition, access to, and occupancy of the Premises. The
Premises shall not be used for any use which is disreputable,

                                       9
<PAGE>

creates extraordinary fire hazards, or results in an increased rate of insurance
on the Building or its contents, or for the storage of any hazardous materials
or substances. If, because of a Tenant Party's acts, the rate of insurance on
the Building or its contents increases, then such acts shall be an Event of
Default, Tenant shall pay to Landlord the amount of such increase on demand, and
acceptance of such payment shall not waive any of Landlord's other rights.
Tenant shall conduct its business and control each other Tenant Party so as not
to create any nuisance or unreasonably interfere with other tenants or Landlord
in its management of the Building.

     9.   Assignment and Subletting.

          (a)  Transfers; Consent. Tenant shall not, without the prior written
consent of Landlord, (1) assign, transfer, or encumber this Lease or any estate
or interest herein, whether directly or by operation of law, (2) permit any
other entity to become Tenant hereunder by merger, consolidation, or other
reorganization, (3) if Tenant is an entity other than a corporation whose stock
is publicly traded, permit the transfer of an ownership interest in Tenant so as
to result in a change in the current control of Tenant, (4) sublet any portion
of the Premises, (5) grant any license, concession, or other right of occupancy
of any portion of the Premises, or (6) permit the use of the Premises by any
parties other than Tenant (any of the events listed in Section 9.(a)(l) through
9.(a)(6) being a "Transfer"). If Tenant requests Landlord's consent to a
Transfer, then Tenant shall provide Landlord with a written description of all
terms and conditions of the proposed Transfer, copies of the proposed
documentation, and the following information about the proposed transferee: name
and address; reasonably satisfactory information about its business and business
history; its proposed use of the Premises; banking, financial, and other credit
information; and general references sufficient to enable Landlord to determine
the proposed transferee's creditworthiness and character. Landlord shall not
unreasonably withhold its consent to any assignment or subletting of the
Premises, provided that the proposed transferee (A) is creditworthy (i.e., can
be reasonably expected to meet its financial obligations as they become due),
(B) has a good reputation in the business community, (C) does not engage in
business similar to those of other tenants in the Building, and (D) is not
another occupant of the Building or person or entity to whom Landlord has
submitted a written proposal to lease space in the Building; otherwise, Landlord
may withhold its consent in its sole discretion. Concurrently with Tenant's
notice of any request for consent to a Transfer, Tenant shall pay to Landlord a
fee of $1,000 to defray all of Landlord's expenses in reviewing such request. If
Landlord consents to a proposed Transfer, then the proposed transferee shall
deliver to Landlord a written agreement whereby it expressly assumes Tenant's
obligations hereunder; however, any transferee of less than all of the space in
the Premises shall be liable only for obligations under this lease that are
properly allocable to the space subject to the Transfer for the period of the
Transfer. Unless otherwise agreed, no Transfer shall release Tenant from its
obligations under this Lease, but rather Tenant and its transferee shall be
jointly and severally liable therefor. Landlord's consent to any Transfer shall
not waive Landlord's rights as to any subsequent Transfers. If an Event of
Default occurs while the Premises or any part thereof are subject to a Transfer,
then Landlord, in addition to its other remedies, may collect directly from such
transferee all rents becoming due to Tenant and apply such rents against Rent.
Tenant authorizes its transferees to make payments of rent directly to Landlord
upon receipt of notice from Landlord to do so. Tenant shall pay for the
reasonable cost of any demising walls or other improvements necessitated by
applicable governmental laws, codes, rules, and regulations regarding a
subletting or assignment.

                                       10
<PAGE>

          (b)  Cancellation. Landlord may, within 30 days after submission of
Tenant's written request for Landlord's consent to an assignment or to
subletting (1) for a period in excess of 36 months, or (2) made at a time when
the remaining length of the Term is 36 months or less, cancel this Lease as to
the portion of the Premises proposed to be sublet or assigned as of the date the
proposed Transfer is to be effective. Landlord shall notify Tenant in writing if
it elects to cancel this Lease as provided herein, and Tenant shall have 15 days
after receipt of such cancellation notice to withdraw its request. If Tenant
timely withdraws its request in writing, then this Lease shall remain in full
force and effect as to the entire Premises. If Tenant does not withdraw its
request and Landlord cancels this Lease as to any portion of the Premises, then
this Lease shall cease for such portion of the Premises and Tenant shall pay to
Landlord all Rent accrued through the cancellation date relating to the portion
of the Premises covered by the proposed Transfer. Thereafter, Landlord may lease
such portion of the Premises to the prospective transferee (or to any other
person) without liability to Tenant.

          (c)  Additional Compensation. Tenant shall pay to Landlord,
immediately upon receipt thereof, the excess of (l) all compensation received by
Tenant for a Transfer less the costs reasonably incurred by Tenant with
unaffiliated third parties in connection with such Transfer (i.e., brokerage
commissions, tenant finish work, and the like) over (2) the Rent allocable to
the portion of the Premises covered thereby.

          (d)  Permitted Transfers. Notwithstanding the foregoing, Tenant may
Transfer all or part of its interest in this Lease or all or part of the
Premises to the following types of entities ("Permitted Transferees") without
the written consent of Landlord (each, a "Permitted Transfer"): (1) Affiliates
of Tenant; and (2) Subsidiaries of Tenant (being any entity in which Tenant owns
more than 50% of the outstanding equity interests); (3) any entity or entities
owned or controlled by any majority shareholder of Tenant; (4) any corporation
resulting from the merger or consolidation of Tenant; or (5) any person or
entity which acquires all of the assets of Tenant as a going concern of the
business that is being conducted on the Premises. Tenant will promptly notify
Landlord of any Permitted Transfer.

     10.  Insurance; Waivers; Subrogation; Indemnity.

          (a)  Insurance. Tenant shall maintain throughout the Term the
following insurance policies: (1) commercial general liability insurance in
amounts of $1,000,000 per occurrence with $2,000,000 in the aggregate or such
other amounts as Landlord may from time to time reasonably require, insuring
Tenant, Landlord, Landlord's agents and their respective affiliates against all
liability for injury to or death of a person or persons or damage to property
arising from the use and occupancy of the Premises, (2) insurance covering the
full value of Tenant's property and improvements, and other property (including
property of others) in the Premises, (3) worker's compensation insurance,
containing a waiver of subrogation endorsement reasonably acceptable to
Landlord, and (4) business interruption insurance. Tenant's insurance shall
provide primary coverage to Landlord when any policy issued to Landlord provides
duplicate or similar coverage, and in such circumstance Landlord's policy will
be excess over Tenant's policy. Tenant shall furnish to Landlord certificates of
such insurance and such other evidence satisfactory to Landlord of the
maintenance of all insurance coverages required hereunder, and Tenant shall
obtain a written

                                       11
<PAGE>

obligation on the part of each insurance company to notify Landlord at least 30
days before cancellation or a material change of any such insurance policies.
All such insurance policies shall be in form, and issued by companies,
reasonably satisfactory to Landlord.

          (b)  Waiver of Negligence; No Subrogation. Landlord and Tenant each
waives any claim it might have against the other for any injury to or death of
any person or persons or damage to or theft, destruction, loss, or loss of use
of any property (a "Loss"), to the extent the same is insured against under any
insurance policy that covers the Building, the Premises, Landlord's or Tenant's
fixtures, personal property, leasehold improvements, or business, or, in the
case of Tenant's waiver, is required to be insured against under the terms
hereof, regardless of whether the negligence of the other party caused such
Loss; however, Landlord's waiver shall not include any deductible amounts on
insurance policies carried by Landlord or to any coinsurance penalty which
Landlord may sustain. Each party shall cause its insurance carrier to endorse
all applicable policies waiving the carrier's rights of recovery under
subrogation or otherwise against the other party.

          (c)  Indemnity. Subject to Section 10.(b), Tenant shall defend,
indemnify, and hold harmless Landlord and its representatives and agents from
and against all claims, demands, liabilities, causes of action, suits,
judgments, actual direct (but not consequential) damages, and expenses
(including reasonable attorneys' fees) arising from (1) any Loss arising from
any occurrence on the Premises (other than a structural failure of the Building)
or (2) Tenant's failure to perform its obligations under this Lease, even though
caused or alleged to be caused by the negligence or fault of Landlord or its
agents (other than a Loss arising from the sole or gross negligence of Landlord
or its agents), and even though any such claim, cause of action, or suit is
based upon or alleged to be based upon the strict liability of Landlord or its
agents. Subject to Section l0.(b), Landlord shall defend, indemnify, and hold
harmless Tenant and its agents from and against all claims, demands,
liabilities, causes of action, suits, judgments, actual direct (but not
consequential) damages, and expenses (including reasonable attorneys' fees) for
any Loss arising from any occurrence in the Building's common areas. The
indemnities set forth in this Section 10.(c) shall survive termination or
expiration of this Lease. If any proceeding is filed for which indemnity is
required hereunder, the indemnifying party agrees, upon request therefor, to
defend the indemnified party in such proceeding at its sole cost utilizing
counsel reasonably satisfactory to the indemnified party.

     11.  Subordination; Attornment; Notice to Landlord's Mortgagee.

          (a)  Subordination. This Lease shall be subordinate to any deed of
trust, mortgage, or other security instrument, or any ground lease, master
lease, or primary lease, that now or hereafter covers all or any part of the
Premises (the mortgagee under any such mortgage or the lessor under any such
lease is referred to herein as a "Landlord's Mortgagee"). Landlord shall use all
commercially reasonable efforts to obtain a Subordination, Recognition and
Attornment Agreement from Landlord's Mortgagee in form reasonably satisfactory
to Tenant, providing that, so long as Tenant is not in default under this Lease,
then Tenant's right to occupy the Premises pursuant to this Lease shall not be
disturbed by any foreclosure or similar action taken by Landlord. Any Landlord's
Mortgagee may elect, at any time, unilaterally, to make this Lease superior to
its mortgage, ground lease, or other interest in the Premises by so notifying
Tenant in writing.

                                       12
<PAGE>

          (b)  Attornment. Tenant shall attorn to any party succeeding to
Landlord's interest in the Premises, whether by purchase, foreclosure, deed in
lieu of foreclosure, power of sale, termination of lease, or otherwise, upon
such party's request, and shall execute such agreements confirming such
attornment as such party may reasonably request.

          (c)  Notice to Landlord's Mortgagee. Tenant shall not seek to enforce
any remedy it may have for any default on the part of Landlord without first
giving written notice by certified mail, return receipt requested, specifying
the default in reasonable detail, to any Landlord's Mortgagee whose address has
been given to Tenant, and affording such Landlord's Mortgagee a reasonable
opportunity to perform Landlord's obligations hereunder.

     12.  Rules and Regulations. Tenant shall comply with the rules and
regulations of the Building which are attached hereto as Exhibit C. Landlord
may, from time to time, change such rules and regulations for the safety, care,
or cleanliness of the Building and related facilities, provided that such
changes are applicable to all tenants of the Building and will not unreasonably
interfere with Tenant's use of the Premises. Tenant shall be responsible for the
compliance with such rules and regulations by each Tenant Party.

     13.  Condemnation.

          (a)  Total Taking. If the entire Building or Premises are taken by
right of eminent domain or conveyed in lieu thereof (a "Taking"), this Lease
shall terminate as of the date of the Taking.

          (b)  Partial Taking - Tenant's Rights. If any part of the Building
becomes subject to a Taking and such Taking will prevent Tenant from conducting
its business in the Premises in a manner reasonably comparable to that conducted
immediately before such Taking for a period of more than 180 days, then Tenant
may terminate this Lease as of the date of such Taking by giving written notice
to Landlord within 30 days after the Taking, and Rent shall be apportioned as of
the date of such Taking. If Tenant does not terminate this Lease, then Rent
shall be abated on a reasonable basis as to that portion of the Premises
rendered untenantable by the Taking.

          (c)  Partial Taking Landlord's Rights. If any material portion, but
less than all, of the Building becomes subject to a Taking, or if Landlord is
required to pay any of the proceeds received for a Taking to a Landlord's
Mortgagee, then Landlord may terminate this Lease by delivering written notice
thereof to Tenant within 30 days after such Taking, and Rent shall be
apportioned as of the date of such Taking. If Landlord does not so terminate
this Lease, then this Lease will continue, but if any portion of the Premises
has been taken, Rent shall abate as provided in the last sentence of Section
13.(b).

          (d)  Award. If any Taking occurs, then Landlord shall receive the
entire award or other compensation for the land on which the Building is
situated, the Building, and other improvements taken, and Tenant may separately
pursue a claim (to the extent it will not reduce Landlord's award) against the
condemnor for the value of Tenant's personal property which Tenant is entitled
to remove under this Lease, moving costs, loss of business, and other claims it
may have.

                                       13
<PAGE>

     14.  Fire or Other Casualty.

          (a)  Repair Estimate. If the Premises or the Building are damaged by
fire or other casualty (a "Casualty"), Landlord shall, within 75 days after such
Casualty, deliver to Tenant a good faith estimate (the "Damage Notice") of the
time needed to repair the damage caused by such Casualty.

          (b)  Landlord's and Tenant's Rights. If a material portion of the
Premises or the Building is damaged by Casualty such that Tenant is prevented
from conducting its business in the Premises in a manner reasonably comparable
to that conducted immediately before such Casualty and Landlord estimates that
the damage caused thereby cannot be repaired within 180 days after the
Casualty, then Tenant may terminate this Lease by delivering written notice to
Landlord of its election to terminate within 30 days after the Damage Notice has
been delivered to Tenant. If Tenant does not so timely terminate this Lease,
then (subject to Section 14.(c)) Landlord shall repair the Building or the
Premises, as the case may be, as provided below, and Rent for the portion of the
Premises rendered untenantable by the damage shall be abated on a reasonable
basis from the date of damage until the completion of the repair, unless a
Tenant Party solely caused such damage, in which case, Tenant shall continue to
pay Rent without abatement.

          (c)  Landlord's Rights. If a Casualty damages a material portion of
the Building, and Landlord makes a good faith determination that restoring the
Premises would be uneconomical, or if Landlord is required to pay any insurance
proceeds arising out of the Casualty to a Landlord's Mortgagee, then Landlord
may terminate this Lease by giving written notice of its election to terminate
within 30 days after the Damage Notice has been delivered to Tenant, and Basic
Rent and Additional Rent shall be abated as of the date of the Casualty.

          (d)  Repair Obligation. If neither party elects to terminate this
Lease following a Casualty, then Landlord shall, within a reasonable time after
such Casualty, begin to repair the Building and the Premises and shall proceed
with reasonable diligence to restore the Building and Premises to substantially
the same condition as they existed immediately before such Casualty; however,
Landlord shall not be required to repair or replace any of the furniture,
equipment, fixtures, and other improvements which may have been placed by, or at
the request of, Tenant or other occupants in the Building or the Premises, and
Landlord's obligation to repair or restore the Building or Premises shall be
limited to the extent of the insurance proceeds actually received by Landlord
for the Casualty in question.

     15.  Personal Property Taxes. Tenant shall be liable for all taxes levied
or assessed against personal property, furniture, or fixtures placed by Tenant
in the Premises. If any taxes for which Tenant is liable are levied or assessed
against Landlord or Landlord's property and Landlord elects to pay the same, or
if the assessed value of Landlord's property is increased by inclusion of such
personal property, furniture or fixtures and Landlord elects to pay the taxes
based on such increase, then Tenant shall pay to Landlord, upon demand, the part
of such taxes for which Tenant is primarily liable hereunder; however, Landlord
shall not pay such amount if Tenant notifies Landlord that it will contest the
validity or amount of such taxes before Landlord makes such payment, and
thereafter diligently proceeds with such contest in accordance with law and if
the non-

                                       14
<PAGE>

payment thereof does not pose a threat of loss or seizure of the Building or
interest of Landlord therein or impose any fee or penalty against Landlord.

     16.  Events of Default. Each of the following occurrences shall be an
"Event of Default":

          (a)  Tenant's failure to pay Rent within ten (10) days after Landlord
has delivered notice to Tenant that the same is due; however, an Event of
Default shall occur hereunder without any obligation of Landlord to give any
notice if Landlord has given Tenant written notice under this Section 16.(a) on
more than one occasion during the twelve (12) month interval preceding such
failure by Tenant;

          (b)  Tenant fails to provide any estoppel certificate as called for in
this Lease and such failure shall continue for ten (10) days after written
notice from Landlord to Tenant of the expiration of the ten-day period provided
in Section 24.(e);

          (c)  Tenant's failure to perform, comply with, or observe any other
non-monetary agreement or obligation of Tenant under this Lease and the
continuance of such failure for a period of more than 30 days after Landlord has
delivered to Tenant written notice thereof; and

          (d)  The filing of a petition by or against Tenant (the term "Tenant"
shall include, for the purpose of this Section 16.(d), any guarantor of Tenant's
obligations hereunder) (1) in any bankruptcy or other insolvency proceeding; (2)
seeking any relief under any state or federal debtor relief law; (3) for the
appointment of a liquidator or receiver for all or substantially all of Tenant's
property or for Tenant's interest in this Lease; or (4) for the reorganization
or modification of Tenant's capital structure; however, if such a petition is
filed against Tenant, then such filing shall not be an Event of Default unless
Tenant fails to have the proceedings initiated by such petition dismissed within
90 days after the filing thereof.

     17.  Remedies. Upon any Event of Default, Landlord may, in addition to all
other rights and remedies afforded Landlord hereunder or by law or equity, take
any of the following actions:

          (a)  Terminate this Lease by giving Tenant written notice thereof, in
which event Tenant shall pay to Landlord the sum of (1) all Rent accrued
hereunder through the date of termination, (2) all amounts due under Section
18.(a), and (3) an amount equal to (A) the total Rent that Tenant would have
been required to pay for the remainder of the Term discounted to present value
at a per annum rate equal to the "Prime Rate" as published on the date this
Lease is terminated by The Wall Street Journal, Southwest Edition, in its
listing of"Money Rates" minus one percent, minus (B) the then present fair
rental value of the Premises for such period, similarly discounted;

          (b)  Terminate Tenant's right to possess the Premises without
terminating this Lease by giving written notice thereof to Tenant, in which
event Tenant shall pay to Landlord (1) all Rent and other amounts accrued
hereunder to the date of termination of possession, (2) all amounts due from
time to time under Section 18.(a), and (3) all Rent and other net sums required
hereunder to be paid by Tenant during the remainder of the Term, diminished by
any net sums thereafter

                                       15
<PAGE>

received by Landlord through reletting the Premises during such period, after
deducting all costs incurred by Landlord in reletting the Premises. Landlord
shall use reasonable efforts to mitigate its damages and relet the Premises on
such terms as Landlord in its sole but reasonable discretion may determine
(including a term different from the Term, rental concessions, and alterations
to, and improvement of, the Premises); however, Landlord shall not be obligated
to relet the Premises before leasing other portions of the Building. Landlord
shall not be liable for, nor shall Tenant's obligations hereunder be diminished
because of, Landlord's failure to relet the Premises or to collect rent due for
such reletting. Tenant shall not be entitled to the excess of any consideration
obtained by reletting over the Rent due hereunder. Reentry by Landlord in the
Premises shall not affect Tenant's obligations hereunder for the unexpired Term;
rather, Landlord may, from time to time, bring an action against Tenant to
collect amounts due by Tenant, without the necessity of Landlord's waiting until
the expiration of the Term. Unless Landlord delivers written notice to Tenant
expressly stating that it has elected to terminate this Lease, all actions taken
by Landlord to dispossess or exclude Tenant from the Premises shall be deemed to
be taken under this Section 17.(b). If Landlord elects to proceed under this
Section 17.(b), it may at any time elect to terminate this Lease under Section
17.(a); or

          (c)  Additionally, in the event Tenant fails to timely pay Rent,
Landlord may alter locks or other security devices at the Premises to deprive
Tenant of access thereto, and Landlord shall not be required to provide a new
key or right of access to Tenant unless Tenant pays the delinquent Rent.

     18.  Payment by Tenant; Non-Waiver.

          (a)  Payment by Tenant. Upon any Event of Default, Tenant shall pay to
Landlord all costs incurred by Landlord (including court costs and reasonable
and necessary attorneys' fees and expenses) in (1) obtaining possession of the
Premises, (2) removing and storing Tenant's or any other occupant's personal
property, (3) if Tenant is dispossessed of the Premises and this Lease is not
terminated, reletting all or any part of the Premises (including brokerage
commissions and other marketing costs incidental to such reletting), (4)
performing Tenant's obligations which Tenant failed to perform, and (5)
enforcing, or advising Landlord of, its rights, remedies, and recourses arising
out of the Event of Default. To the full extent permitted by law, Landlord and
Tenant agree the federal and state courts of Dallas County, Texas shall have
exclusive jurisdiction over any matter relating to or arising from this Lease
and the parties' rights and obligations under this Lease.

          (b)  No Waiver. Landlord's acceptance of Rent following an Event of
Default shall not waive Landlord's rights regarding such Event of Default. No
waiver by Landlord of any violation or breach of any of the terms contained
herein shall waive Landlord's rights regarding any future violation of such
term. Landlord's acceptance of any partial payment of Rent shall not waive
Landlord's rights with regard to the remaining portion of the Rent that is due,
regardless of any endorsement or other statement on any instrument delivered in
payment of Rent or any writing delivered in connection therewith; accordingly,
Landlord's acceptance of a partial payment of Rent shall not constitute an
accord and satisfaction of the full amount of the Rent that is due.

                                       16
<PAGE>

     19.  Landlord's Lien. In addition to the statutory landlord's lien, Tenant
grants to Landlord, to secure performance of Tenant's obligations hereunder, a
security interest in all goods (including equipment and inventory), fixtures,
and other personal property, except negotiable securities, books, accounts or
files, of Tenant situated on the Premises, and all proceeds thereof (the
"Collateral"), and the Collateral shall not be removed from the Premises without
the prior written consent of Landlord (other than in Tenant's ordinary course of
business) until all obligations of Tenant have been fully performed. Upon the
occurrence of an Event of Default, Landlord may, in addition to all other
remedies, without notice or demand except as provided below, exercise the rights
afforded to a secured party under the Texas Uniform Commercial Code (the "UCC").
Tenant grants to Landlord a power of attorney to execute and file any financing
statement or other instrument necessary to perfect Landlord's security interest
under this Section 19, which power is coupled with an interest and is
irrevocable during the Term. Landlord may also file a copy of this Lease as a
financing statement to perfect its security interest in the Collateral. Landlord
hereby subordinates its statutory lien, as well as the security interest granted
to it under this Section 19, to all "purchase money security interests" (as such
term is defined in the UCC) in the Collateral, and Landlord shall, at Tenant's
expense, execute such documentation to evidence such subordination as the owner
of any such purchase money security interest may reasonably request.

     20.  Surrender of Premises. No act by Landlord shall be deemed an
acceptance of a surrender of the Premises, and no agreement to accept a
surrender of the Premises shall be valid unless it is in writing and signed by
Landlord. At the expiration or termination of this Lease, Tenant shall deliver
to Landlord the Premises with all improvements located therein in good repair
and condition, broom-clean, reasonable wear and tear (and condemnation and
Casualty damage not caused by Tenant, as to which Sections 13 and 14 shall
control) excepted, and shall deliver to Landlord all keys to the Premises.
Provided that Tenant has performed all of its obligations hereunder, Tenant may
remove all unattached trade fixtures, furniture, supplemental HVAC equipment,
telecommunications equipment, signage (as provided in Section 26), Tenant's
Equipment (as provided in Section 25), and personal property placed in or on the
Premises or Building by Tenant, and shall remove such alterations, additions,
improvements, trade fixtures, personal property, equipment, wiring, cabling and
furniture as required in accordance with Section 7.(a); provided however, that
Tenant shall not be required to remove any cabling installed as part of
construction of Tenant's initial improvements in the Premises as specified in
Exhibit D. Tenant shall repair all damage caused by such removal. All items not
so removed shall be deemed to have been abandoned by Tenant after ten (10) days
prior written notice to Tenant, and may be appropriated, sold, stored,
destroyed, or otherwise disposed of by Landlord without notice to Tenant and
without any obligation to account for such items. The provisions of this Section
20 shall survive the end of the Term.

     21.  Holding Over. If Tenant fails to vacate the Premises at the end of the
Term, then Tenant shall be a tenant at will and, in addition to all other
damages (including damages incurred by Landlord arising out of any claims made
by any succeeding tenant founded upon such failure to surrender, and any lost
profits to Landlord resulting therefrom) and remedies to which Landlord may be
entitled for such holding over, Tenant shall pay, in addition to the other Rent,
a daily Basic Rent equal to the greater of (a) 150% of the daily Basic Rent
payable during the last month of the Term, or (b) 125% of the prevailing rental
rate in the Building for similar space. The provisions of this

                                       17
<PAGE>

Section 21 shall not be deemed to limit or constitute a waiver of any other
rights or remedies of Landlord provided herein or at law.

     22.  Certain Rights Reserved by Landlord. Provided that the exercise of
such rights does not unreasonably interfere with Tenant's occupancy of the
Premises, Landlord shall have the following rights:

          (a)  To decorate and to make inspections, repairs, alterations,
additions, changes, or improvements, whether structural or otherwise, in and
about the Building, or any part thereof to enter upon the Premises and, during
the continuance of any such work, to temporarily close doors, entryways, public
space, and corridors in the Building; to interrupt or temporarily suspend
Building services and facilities; to change the name of the Building; and to
change the arrangement and location of entrances or passageways, doors, and
doorways, corridors, elevators, stairs, restrooms, or other public parts of the
Building;

          (b)  To take such reasonable measures as Landlord deems advisable for
the security of the Building and its occupants; evacuating the Building for
cause, suspected cause, or for drill purposes; temporarily denying access to the
Building; and closing the Building after normal business hours and on Sundays
and holidays, subject, however, to Tenant's right to enter when the Building is
closed after normal business hours under such reasonable regulations as Landlord
may prescribe from time to time; and

          (c)  Upon 24 hours advance prior notice to Tenant, to enter the
Premises at reasonable hours to show the Premises to prospective purchasers,
lenders, or, during the last 12 months of the Term, tenants.

     23.  Substitution Space. [Intentionally omitted].

     24.  Miscellaneous.

          (a)  Landlord Transfer. Landlord may transfer any portion of the
Building and any of its rights under this Lease. If Landlord assigns its rights
under this Lease, then Landlord shall thereby be released from any further
obligations hereunder, provided that the assignee assumes Landlord's obligations
hereunder in writing.

          (b)  Landlord's Liability. The liability of Landlord to Tenant for any
default by Landlord under the terms of this Lease shall be limited to Tenant's
actual direct, but not consequential, damages therefor and shall be recoverable
only from the interest of Landlord in the Building, and Landlord shall not be
personally liable for any deficiency. This Section shall not limit any remedies
which Tenant may have for Landlord's defaults which do not involve the personal
liability of Landlord.

          (c)  Force Majeure. Other than for Tenant's obligations under this
Lease that can be performed by the payment of money (e.g., payment of Rent and
maintenance of insurance), whenever a period of time is herein prescribed for
action to be taken by either party hereto, such

                                       18
<PAGE>

party shall not be liable or responsible for, and there shall be excluded from
the computation of any such period of time, any delays due to strikes, riots,
acts of God, war, governmental laws, regulations, or restrictions, or any other
similar causes of any kind whatsoever which are beyond the control of such
party.

          (d)  Brokerage. Neither Landlord nor Tenant has dealt with any broker
or agent in connection with the negotiation or execution of this Lease, other
than Fults Associates, Inc., Robert Deptula, and Transwestern Property Company
whose commission shall be paid by Landlord pursuant to separate agreements.
Tenant and Landlord shall each indemnify the other against all costs, expenses,
attorneys' fees, and other liability for commissions or other compensation
claimed by any broker or agent claiming the same by, through, or under the
indemnifying party.

          (e)  Estoppel Certificates. From time to time, Tenant shall furnish to
any party designated by Landlord, within ten days after Landlord has made a
request therefor, a certificate signed by Tenant confirming and containing such
factual certifications and representations as to this Lease as Landlord may
reasonably request.

          (f)  Notices. All notices and other communications given pursuant to
this Lease shall be in writing and shall be (1) mailed by first class, United
States Mail, postage prepaid, certified, with return receipt requested, and
addressed to the parties hereto at the address specified next to their signature
block, (2) hand delivered to the intended address, or (3) sent by prepaid
telegram, cable, facsimile transmission, or telex followed by a confirmatory
letter. All notices shall be effective upon delivery to the address of the
addressee. The parties hereto may change their addresses by giving notice
thereof to the other in conformity with this provision.

          (g)  Separability. If any clause or provision of this Lease is
illegal, invalid, or unenforceable under present or future laws, then the
remainder of this Lease shall not be affected thereby and in lieu of such clause
or provision, there shall be added as a part of this Lease a clause or provision
as similar in terms to such illegal, invalid, or unenforceable clause or
provision as may be possible and be legal, valid, and enforceable.

          (h)  Amendments; and Binding Effect. This Lease may not be amended
except by instrument in writing signed by Landlord and Tenant. No provision of
this Lease shall be deemed to have been waived by Landlord unless such waiver is
in writing signed by Landlord, and no custom or practice which may evolve
between the parties in the administration of the terms hereof shall waive or
diminish the right of Landlord to insist upon the performance by Tenant in
strict accordance with the terms hereof. The terms and conditions contained in
this Lease shall inure to the benefit of and be binding upon the parties hereto,
and upon their respective successors in interest and legal representatives,
except as otherwise herein expressly provided. This Lease is for the sole
benefit of Landlord and Tenant, and, other than Landlord's Mortgagee, no third
party shall be deemed a third party beneficiary hereof.

          (i)  Quiet Enjoyment. Provided Tenant has performed all of its
obligations hereunder, Tenant shall peaceably and quietly hold and enjoy the
Premises for the Term, without

                                       19
<PAGE>

hindrance from Landlord or any party claiming by, through, or under Landlord,
but not otherwise, subject to the terms and conditions of this Lease.

          (j)  No Merger. There shall be no merger of the leasehold estate
hereby created with the fee estate in the Premises or any part thereof if the
same person acquires or holds, directly or indirectly, this Lease or any
interest in this Lease and the fee estate in the leasehold Premises or any
interest in such fee estate.

          (k)  No Offer. The submission of this Lease to Tenant shall not be
construed as an offer, and Tenant shall not have any rights under this Lease
unless Landlord executes a copy of this Lease and delivers it to Tenant.

          (1)  Entire Agreement. This Lease constitutes the entire agreement
between Landlord and Tenant regarding the subject matter hereof and supersedes
all oral statements and prior writings relating thereto. Except for those set
forth in this Lease, no representations, warranties, or agreements have been
made by Landlord or Tenant to the other with respect to this Lease or the
obligations of Landlord or Tenant in connection therewith. The normal rule of
construction that any ambiguities be resolved against the drafting party shall
not apply to the interpretation of this Lease or any exhibits or amendments
hereto.

          (m)  Waiver of Jury Trial. [Intentionally omitted].

          (n)  Governing Law. This Lease shall be governed by and construed in
accordance with the laws of the State in which the Premises are located.

          (o)  Joint and Several Liability. [Intentionally omitted].

          (p)  Financial Reports. Within 15 days after Landlord's request,
Tenant will furnish Tenant's most recent audited financial statements (including
any notes to them) to Landlord, or, if no such audited statements have been
prepared, such other financial statements (and notes to them) as may have been
prepared by an independent certified public accountant or, failing those,
Tenant's internally prepared financial statements; provided that if Tenant
ceases to be a publicly held company, it shall provide audited financial
statements to Landlord. Tenant will discuss its financial statements with
Landlord. Landlord will not disclose any aspect of Tenant's financial statements
that Tenant designates to Landlord as confidential except (1) to Landlord's
lenders or prospective purchasers of the Building, (2) in litigation between
Landlord and Tenant, and (3) if required by court order.

          (q)  Landlord's Fees. Whenever Tenant requests Landlord to take any
action or give any consent required or permitted under this Lease, Tenant will
reimburse Landlord for Landlord's reasonable and necessary costs incurred in
reviewing the proposed action or consent, including without limitation
reasonable attorneys', engineers' or architects' fees, within 30 days after
Landlord's delivery to Tenant of a statement of such costs. Tenant will be
obligated to make such reimbursement without regard to whether Landlord consents
to any such proposed action.

                                       20
<PAGE>

          (r)  Telecommunications. Tenant and its telecommunications companies,
including but not limited to local exchange telecommunications companies and
alternative access vendor services companies shall have no right of access to
and within the Building, for the installation and operation of
telecommunications systems including but not limited to voice, video, data, and
any other telecommunications services provided over wire, fiber optic,
microwave, wireless, and any other transmission systems, for part or all of
Tenant's telecommunications  within or on the roof of the Building and from the
Building to any other location without Landlord's prior written consent, which
shall not be unreasonably withheld or delayed.

          (s)  General Definitions. The following terms shall have the following
meanings:  "Laws" means all federal, state, and local laws, rules and
regulations, all court orders, all governmental directives and governmental
orders, and all restrictive covenants affecting the Property, and "Law" means
any of the foregoing; "Affiliate" means any person or entity which, directly or
indirectly, controls, is controlled by, or is under common control with the
party in question; "Tenant Party" shall include Tenant, any assignees claiming
by, through, or under Tenant, any subtenants claiming by, through, or under
Tenant, and any agents, contractors, employees, and invitees of the foregoing
parties; and "including" means including, without limitation.

          (t)  Confidentiality. [Intentionally omitted].

          (u)  List of Exhibits and Schedules. All exhibits and schedules
attached hereto are incorporated herein by this reference.

          Exhibit A      -  Outline of Premises
          Exhibit B      -  Legal Description of Building
          Exhibit C      -  Building Rules and Regulations

     25.  Use of Roof. Provided that Tenant complies with the terms of this
Section 25, Tenant may, at its risk and expense, install, operate, maintain, and
repair telecommunications and wireless communications equipment and HVAC
equipment and related wiring for its or its Permitted Transferee's use
(collectively, the "Tenant's Equipment") on the roof of the Building at a
location approved, which approval shall not be unreasonably withheld or delayed,
by Landlord. Before installing Tenant's Equipment, Tenant shall submit to
Landlord for its approval (which approval shall not be unreasonably withheld or
delayed and shall be in Landlord's sole but reasonable discretion) plans and
specifications which (a) specify in detail the type, design, location, and size,
of Tenant's Equipment, and (b) are sufficiently detailed to allow for the
installation of Tenant's Equipment in a good and workmanlike manner and in
accordance with all Laws. If Landlord

                                       21
<PAGE>

approves of such plans, Tenant shall install (in a good and workmanlike manner),
maintain and use Tenant's Equipment in accordance with all Laws and shall obtain
all permits required for the installation and operation thereof; copies of all
such permits must be submitted to Landlord before Tenant begins to install
Tenant's Equipment. Tenant shall thereafter maintain all permits necessary for
the maintenance and operation of Tenant's Equipment while it is on the Building
and operate and maintain Tenant's Equipment in such a manner so as not to
unreasonably interfere with any other satellite, antennae, or other equipment on
the Building's roof or in the Building. Landlord may require that Tenant screen
Tenant's Equipment with a parapet wall or other screening device acceptable to
Landlord. Tenant shall maintain Tenant's Equipment and the screening therefor in
good repair and condition. Tenant shall, at its risk and expense, commence
removal of Tenant's Equipment, within five days after the occurrence of any of
the following events: (1) the termination of Tenant's right to possess the
Premises; (2) the termination of the Lease; (3) the expiration of the Term; or
(4) Tenant's vacating the Premises and shall thereafter, at its risk and
expense, diligently and continuously pursue such removal to completion. If
Tenant fails to do so, Landlord may, after thirty (30) days of Tenant's receipt
of Landlord's prior written notice for Tenant to so remove Tenant's Equipment,
remove Tenant's Equipment and store or dispose of it in any manner Landlord
deems appropriate without liability to Tenant; Tenant shall reimburse Landlord
for all reasonable costs incurred by Landlord in connection therewith within
thirty (30) days after Landlord's request therefor. Tenant shall repair any
damage to the Building caused by or relating to Tenant's Equipment, including
that which is caused by its installation, maintenance, use, or removal and shall
indemnify Landlord against all reasonable costs and actual direct (but not
consequential) liabilities, losses, and damages (a "Loss") arising from the
installation, maintenance, use, or removal of Tenant's Equipment, including that
caused by Landlord's negligence (unless the Loss in question was caused by
Landlord's sole or gross negligence or willful misconduct). All work relating to
Tenant's Equipment and the roof shall, at Tenant's expense, be performed by
Landlord's roofing contractor. Tenant shall pay to Landlord monthly rent for the
use of the space necessary to maintain Tenant's Equipment equal to the market
monthly rate for similar spaces and for similar uses in the Comparable
Buildings, as reasonably determined by Landlord from time to time which shall be
payable contemporaneously with the payment of Basic Rent.

     26.  Signage. Subject to Landlord's prior approval, which shall not be
unreasonably withheld or delayed, of the location, design, size, color, material
composition, and plans and specifications therefor, and provided Tenant occupies
at least two full floors of the Building, Tenant shall have the exclusive right
(unless any other tenant occupies more space in the Building than Tenant, in
which case such other tenant shall, if it so requests, have the right), at its
sole risk and expense, (a) to construct one building fascia sign (the "Sign") on
the Building, (b) to place (in the highest tenant identification position)
identification letters on the monument sign for the Building fronting on Highway
161 and (c) if Landlord permits tenant signage on the monument sign for the
Building fronting on Highway 114, to place (in the second highest tenant
identification position) identification letters thereon. Landlord shall install
no other, or permit any other tenant (other than a tenant occupying more space
in the Building than Tenant as provided in the preceding sentence) to install
another, sign on the exterior facade of the Building without Tenant's prior
written consent. Such monument signs and the lettering thereon will generally be
as reflected in Schedule 26. If Landlord, in its sole discretion, elects to
position a monument sign for the Building at Campus Circle Drive, and if
Landlord allows tenant's signage at the Campus Circle Drive entrance to the
Building,

                                       22
<PAGE>

then Tenant will (provided it occupies at least two full floors of the Building)
be entitled (unless any other tenant occupies more space in the Building than
Tenant, in which case such other tenant shall, if it so requests, be entitled)
to place (in the second highest tenant identification position), identification
letters on such monument sign. The foregoing monument signs shall be constructed
at Landlord's expense, but Tenant shall be responsible for the cost of its
lettering on the monument signs. Tenant shall erect the Sign in accordance with
the approved plans and specifications, in a good and workmanlike manner, in
accordance with all laws, regulations, restrictions (governmental or otherwise),
and architectural guidelines in effect for the area in which the Building is
located and will obtain all requisite approvals thereunder (the "Sign
Requirements"), and in a manner so as not to unreasonably interfere with the use
of the Building grounds while such construction is taking place; thereafter,
Tenant shall maintain the Sign in a good, clean, and safe condition in
accordance with the Sign Requirements. After the end of the Term or after
Tenant's right to possess the Premises has been terminated pursuant to Section
17.(b), Landlord may require that Tenant remove the Sign by delivering to Tenant
written notice thereof within 30 days after the end of the Term. If Landlord so
requests, Tenant shall within thirty (30) days after Tenant's receipt of such
notice remove the Sign, and Tenant shall remove all of its lettering from
monument signs, repair all damage caused thereby, and, in the case of the Sign,
restore the Building to its condition before the installation of the Sign within
thirty (30) days after Landlord's request therefor. If Tenant fails to timely do
so, Landlord may, without compensation to Tenant, unless Tenant claims and
removes the Sign and/or any lettering from the monument signs on or before
thirty (30) days after Tenant's receipt of Landlord's prior written notice, (1)
use the Sign or (2) at Tenant's expense, remove the Sign and/or any lettering
from monument signs, perform the related restoration and repair work and, in the
case of the Sign, dispose of the Sign in any manner Landlord deems appropriate.
Tenant shall defend, indemnify, and hold harmless Landlord from all losses,
claims, costs and liabilities arising in connection with or relating to the
construction, installation, maintenance, use, or removal of the Sign, including
those arising from Landlord's negligence. The rights granted to Tenant under
this Section 26 may not be assigned to any party, except to a Permitted
Transferee in connection with a Permitted Transfer pursuant to Section 9.(d)
herein.

     27.  Early Occupancy. If the Commencement Date is postponed to May 1, 1998
due to delay caused by Landlord, as contemplated in Exhibit D, then Tenant shall
have the right after January 19, 1998, to occupy the Premises prior to the
Commencement Date of this Lease. Upon such early access, Tenant shall be
responsible for (a) having in full force and effect all insurance required under
the Lease, and (b) prompt payment of all utility costs for the Premises incurred
after the earlier of Tenant's occupancy or the Commencement Date of this Lease.
Landlord and Tenant agree that Tenant's early occupancy of the Premises shall be
at Tenant's sole risk. Tenant's early occupancy of the Premises shall be subject
to all of the provisions of this Lease. Early occupancy of the Premises shall
not advance the expiration date of the Lease. Tenant shall pay Basic Rent, pro
rata based on the space actually occupied for the conduct of Tenant's business,
for the right of early occupancy of the Premises.

     28.  Right to Recapture. If Tenant vacates one or more floors of the
Premises for a period in excess of one year, Landlord will have the option to
terminate this Lease as to such vacated space by delivering to Tenant 60-days
prior written notice of such decision. Tenant shall then have 30 days following
expiration of such 60-day period to notify Landlord in writing that it will
reoccupy

                                       23

the vacated space and to reoccupy the space. If Tenant so notifies Landlord and
reoccupies the vacated space within such 30-day period, then this Lease shall
remain in full force and effect as to the entire Premises. If Tenant fails to so
notify Landlord or to reoccupy the space within such 30-day period, this Lease
will automatically terminate as to the vacated space at the expiration of the
30-day period and both parties will be relieved of all rights, duties or
obligations hereunder with respect to such space, except for duties and
obligations accruing prior to such termination, which will be required to be
satisfied in accordance with the terms of this Lease.

     29.  Other Provisions. LANDLORD AND TENANT EXPRESSLY DISCLAIM ANY IMPLIED
WARRANTY THAT THE PREMISES ARE SUITABLE FOR TENANT'S INTENDED COMMERCIAL
PURPOSE.
