                         OFFICE BUILDING LEASE AGREEMENT

         THIS OFFICE BUILDING LEASE AGREEMENT (the "Lease") is executed on the
date(s) set forth in the signature lines below, to be effective as of the 1st
day of July, 2002, between 4901 LBJ Limited Partnership as "Landlord," and IDX
Information Systems Corporation, as "Tenant."

1.       DEFINITIONS AND BASIC PROVISIONS:

         a.    BASIC LEASE  INFORMATION.  The definitions and basic
provisions set forth in the Basic Lease  Information (the "Basic Lease
Information") executed by Landlord and Tenant contemporaneously herewith are
incorporated herein by reference for all purposes.

         b.    AGREED RENTABLE AREA. The Agreed Rentable Area of the Premises is
hereby stipulated to be the "Agreed Rentable Area of the Premises" set forth in
the Basic Lease Information, irrespective of whether the same should be more or
less as a result of minor variations from the construction of Tenant's
improvements. The Agreed Rentable Area of the Building is hereby stipulated to
be the "Agreed Rentable Area of the Building" set forth in the Basic Lease
Information, irrespective of whether the same should be more or less as a result
of minor variations resulting from actual construction or repair of the
Building. In the event that additional rentable area is added to the Premises,
the measurement thereof shall be performed in accordance with the Standard
Method for Measuring Floor Area in Office Buildings, as promulgated by the
Building Owners and Managers Association.

2.       LEASE GRANT:

         Subject to the terms of this Lease, Landlord leases to Tenant, and
Tenant leases from Landlord, the Premises. In addition, Tenant shall have the
non-exclusive right, along with Landlord and all other tenants in the Building,
and their invitees, to use areas designated by Landlord to be the common areas
in the Building and the Appurtenant Facilities, except any portions thereof
designated for the use of specific tenants. Landlord also grants to Tenant a
license to place one antenna on the roof of the Building, for uses ancillary to
its business. The placement of the antenna shall be subject to prior
coordination with Landlord and is subject to reasonable rules and regulations
established by Landlord.

3.       TERM:

         If the Commencement Date is not the first day of a calendar month, then
the Term shall be extended by the time between the Commencement Date and the
first day of the next month. In the event Tenant occupies the Premises prior to
the scheduled Commencement Date, the Commencement Date shall be defined as the
date such occupancy commences. Tenant's obligation to pay Rent hereunder shall
commence as of the Commencement Date as herein defined. By occupying the
Premises, Tenant shall be deemed to have accepted the Premises in their
condition as of the date of such occupancy. Landlord shall have the right, but
not the obligation, to deliver to Tenant a letter (the "Confirmation Letter")
confirming (i) the Commencement Date, (ii) that Tenant has accepted the
Premises, and (iii) that Landlord has performed all of its obligations, if any,
with respect to the condition of the Premises (except for punch-list items
specified in such Confirmation Letter). All information set forth in the
Confirmation Letter shall be deemed correct and binding on both Landlord and
Tenant, unless Tenant objects to any such information in writing to Landlord
within ten (10) days of Tenant's receipt of the Confirmation Letter. If
requested by Landlord, Tenant shall execute and deliver to Landlord, within ten

<PAGE>

(10) days after Landlord has requested same, a copy of the Confirmation Letter,
although Tenant's failure to execute or deliver the same shall not limit the
binding nature thereof if Tenant fails to object in writing to any information
set forth therein within the time period provided in this Section 3.

4.       RENT:

         a.    PAYMENT. Tenant shall timely pay to Landlord the Basic Rental and
all additional sums to be paid by Tenant to Landlord under this Lease, including
the amounts set forth in Section 4b., without notice, demand, counterclaim,
set-off or abatement, at Landlord's Address (or such other address as Landlord
may from time to time designate in writing to Tenant). Basic Rental adjustment
as herein provided, shall be payable monthly in advance. The first monthly
installment of Basic Rental shall be payable contemporaneously with the
execution of this Lease, and a like monthly installment of Basic Rental shall be
due on the first day of the second full calendar month during the Term. Basic
Rental for any fractional month at the beginning of the Term shall be prorated
and shall be due on the Commencement Date.

         b.    OPERATING EXPENSE ESCALATOR. Tenant shall pay an amount equal to
the excess ("Excess Operating Expense") of Tenant's Proportionate Share of the
actual Operating Expenses for each calendar year or part thereof during the
Term, over the Base Year Expense Stop. Base Year for the determination of the
Expense Stop is calculated by determining the actual Operating Expenses for the
period between January 1 and December 31 of the year 2002. Landlord may make a
good faith estimate of the Excess Operating Expense to be due by Tenant
beginning on the first day of the first Calendar Year, and, unless Landlord
delivers to Tenant a revision of the estimated Excess Operating Expense, Tenant
shall pay to Landlord, on the first day of each calendar month, beginning
January 1st of the first year of the lease term, an amount equal to the
estimated Excess Operating Expense for such upcoming month during the Term.
Landlord may collect such amount in a lump sum, to be due within 30 days after
Landlord furnishes to Tenant the annual statement of actual Operating Expenses.
From time to time during any Lease Year occurring after the First Lease Year,
Landlord may estimate and re-estimate the Excess Operating Expense to be due by
Tenant for that Lease Year and deliver a copy of the estimate or re-estimate to
Tenant. Thereafter, the monthly installments of Excess Operating Expense payable
by Tenant shall be appropriately adjusted in accordance with the estimations so
that, by the end of the Lease Year in question, Tenant shall have paid all of
the Excess Operating Expense as estimated by Landlord. Any amounts paid based on
such an estimate shall be subject to adjustment pursuant to Section 4d. when
actual Operating Expenses are available for such Lease Year.

         c.    OPERATING EXPENSES. For the purposes of this Section 4, the term
"Operating Expenses" shall mean all expenses and disbursements of every kind
(subject to the limitations set forth below) which Landlord incurs, pays or
becomes obligated to pay in connection with the ownership, operation, and
maintenance of the Building and Appurtenant Facilities, determined in accordance
with generally accepted federal income tax basis accounting principles
consistently applied, including, but not limited to, the following:

                  i.     Reasonable wages and salaries (including management
fees) of all employees engaged in the operation, repair, maintenance, and
security of the Building and Appurtenant Facilities, including taxes, insurance
and benefits relating thereto:

                  ii.    All  tools,  equipment,  supplies  and  materials  used
solely  in  the  operation,   maintenance,  repair, replacement, and security of
the Building and Appurtenant Facilities;

                                       2
<PAGE>

                  iii.   Annual cost of all capital improvements and
replacements made to the Building and Appurtenant Facilities which although
capital in nature can reasonably be expected to reduce the normal operating
costs of the Building and Appurtenant Facilities, as well as all capital
improvements made in order to comply with any law hereafter promulgated by any
governmental authority relating to energy, conservation, public safety or
security, as amortized over the greater of the useful economic life of such
improvements as determined by Landlord in its reasonable discretion (without
regard to the period over which the improvements may be depreciated or amortized
for federal income tax purposes);

                  iv.    Costs of all standard utilities for the Building and
Appurtenant Facilities, including costs of water, sewer and power for heating,
lighting, air condition and ventilating (excluding those costs billed to
specific tenants);

                  v.     Costs of any insurance applicable to the Building and
Appurtenant Facilities and Landlord's personal property used in connection
therewith;

                  vi.    All taxes and 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, the
Land and the Appurtenant Facilities (or the operation or leasing thereof),
including without limitation, any gross revenue tax, sales tax, excise tax,
value-added tax, or similar tax; excluding however, Direct Taxes (as defined in
Paragraph 4f. hereof), federal and state taxes on income (collectively,
"Taxes"); if the present method of taxation changes so that in lieu of the whole
or any part of any Taxes levied on the Land, Building or Appurtenant Facilities,
there is levied on Landlord a capital tax directly on the rents received
therefrom or a franchise tax, assessment, or charges based, in whole or in part,
upon such rents for the Building or Appurtenant Facilities, then all such taxes,
assessments, or charges, or the part thereof so based, shall be deemed to be
included with the term "Taxes" for the purposes hereof;

                  vii.   Costs of repairs and general maintenance of the
Building and Appurtenant Facilities;

                  viii.  Costs of service or maintenance contracts with
independent contractors for the operation, maintenance, repair, or security of
the Building and Appurtenant Facilities (including, without limitation, alarm
service, window cleaning, and elevator maintenance;

                  ix.    Costs of consulting, accounting and legal services.

         There are specifically excluded from the definition of the term
"Operating Expenses" costs (1) for capital improvements made to the Building,
other than capital improvements described in subparagraph (iii) above and except
for items which though capital for accounting purposes, are properly considered
maintenance and repair items such as painting of common areas, replacement of
carpet in elevator lobbies, and the like; (2) for repair, replacements and
general maintenance paid by the proceeds of insurance or by the Tenant or other
third parties, and alterations attributed solely to tenants of the Building
other than Tenant; (3) for interest, amortization or other payments on loans to
Landlord; (4) for depreciation and amortization of the Building; (5) for leasing
commissions; (6) for renovating or otherwise improving space for occupants of
the Building or vacant space in the Building; (7) for correcting defects in the
construction of the Building and Appurtenant Facilities; and (8) for federal
income taxes imposed on or measured by the income of Landlord from the operation
of the Building. Tenant, at Tenant's sole cost and expense, shall have the right
to audit Landlord's books and records relating to Operating Expenses and
Landlord agrees to make available to Tenant upon at least ten (10) days prior

                                       3
<PAGE>

written notice from Tenant to Landlord, its books and records relevant to such
an audit.

         d.    ADJUSTMENT. The annual cost statement shall include a statement
of Landlord's actual Operating Expenses for the previous year adjusted as
provided in Section 4e. If the annual cost  statement  reveals  that Tenant paid
more for Operating Expenses than the actual Excess Operating Expense in the year
for which such  statement  was prepared,  then  Landlord,  at its option,  shall
credit against Excess Operating Expenses next month or reimburse Tenant for such
excess if Lease is  terminated;  likewise,  if Tenant  paid less than the actual
Excess Operating Expense,  then Tenant shall pay Landlord such deficiency within
thirty (30) days after delivery of such annual cost statement.

         e.    GROSS-UP. With respect to any calendar year or partial calendar
year in which 95% of the  Rentable  Area of the  Building is not  occupied,  the
Operating  Expenses for such period that vary with  occupancy may, at Landlord's
option in its sole  discretion,  for the  purposes  hereof,  be increased to the
amount which would have been incurred had 95% of the entire Rentable Area of the
Building been occupied,  based on good faith  estimates made by Landlord and the
management company managing the Building.

         f.    DIRECT TAXES. At the same time and in the same manner as the
payment of Basic Rental hereunder, Tenant shall pay any gross revenue tax, sales
tax, excise tax,  value-added tax,  privilege tax, or similar tax imposed by any
government  or  governmental  agency  upon  Tenant or Landlord on account of the
Lease or the payment of Rent hereunder ("Direct Taxes").

        g.     TENANT AUDIT. Tenant shall have the right to perform, no more
than once in any calendar year, an annual audit on Landlord's books and records
which reflect Operating Expenses to verify Landlord's calculation of actual
Operating Expenses for the prior calendar year, provided that (i) such audit
shall be commenced,  if at all, on or before one hundred eighty (180) days after
the receipt of the annual statement of actual Operating  Expenses from Landlord,
(ii) such audit shall be performed during  Landlord's  normal business hours, at
the place where Landlord  maintains its records (or such other place as Landlord
shall  deliver the  appropriate  records)  and only after  Landlord has received
thirty (30) days prior written notice,  (iii) such audit shall be conducted by a
certified public accountant  reasonably  acceptable to Landlord,  and such audit
services shall not be provided on a contingency fee basis, (iv) the auditor's
report reflecting the results of such audit shall be promptly delivered to
Landlord, (v) such audit and/or inspection shall commence within thirty (30)
days after Landlord makes such books and records available to Tenant's auditor
and thereafter proceed reasonably to conclusion, (vi) such audit and/or
inspection shall not unreasonably interfere with the conduct of Landlord's
business, and (vii) both Tenant and the accounting firm conducting the audit
and/or inspection shall execute a confidentiality agreement for the benefit of
Landlord, in the form reasonably requested by Landlord, prior to the
commencement of the audit or inspection. This paragraph shall not be construed
to limit or abate Tenant's obligation to pay the Operating Expenses when due as
set forth in this Lease. If such audit conducted by Tenant discloses that Tenant
has overpaid Operating Expenses, then, after verification of such audit by
Landlord or by accountants selected by Landlord, any overpayment shall be
refunded to Tenant (so long as Tenant is not then in default of any of the terms
of this Lease, in which event such overpayment shall be applied against any
amount Tenant owes as a result of such default) within thirty (30) days after
the verification of the audit. Failure by Tenant to contest or dispute the
allocation of Operating Expenses within the time period set forth above for
performance of an audit (a) shall be deemed a waiver of the applicable audit or
dispute right and any right to contest the Operating Expenses for the applicable
calendar year; and (b) shall be deemed acceptance of the Operating Expenses

                                       4
<PAGE>

charges as submitted to and reviewed by Tenant. In the event the audit reveals
that Landlord has overstated Operating Expenses by in excess of four percent
(4%), Landlord shall reimburse Tenant for the cost of the audit. The foregoing
provisions shall survive termination or expiration of the Lease.

         h.    Survivability  of Obligations.  All obligations of Tenant to pay
Rent accrued prior to termination of the Lease shall survive such termination.

5.       DELINQUENT PAYMENT; LATE CHARGES:

         All Rent to be paid by Tenant to Landlord shall be in lawful money of
the United States of America and shall be paid without deduction or offset,
prior notice or demand, at the address set forth in the Basic Lease Information,
or at such other places as may be designated from time to time by Landlord. In
the event a check is submitted by Tenant for payment, and is returned for
insufficient funds, a $25.00 handling fee will be assessed by Landlord. If
thereafter a second check is returned for insufficient funds, another handling
fee in the amount of $50.00 will be assessed, and all future payments thereafter
must be made in cash or cashier's or certified check. In the event any Rent is
not received within 10 days after it is due for any reason whatsoever, then in
addition to the past due amount Tenant shall pay to Landlord interest on the
Rent then past due at a rate equal to the lesser of (i) 18% per annum, or (ii)
the maximum contractual rate which could legally be charged in the event of a
loan of such Rent to Tenant, such interest to accrue continuously on any unpaid
balance due to Landlord by Tenant during the period commencing with the Rent due
and terminating with the date on which Tenant makes full payment of all amounts
owing to Landlord at the time of said payment. Any such interest payment shall
be payable as additional Rent under this Lease and shall be payable immediately
on demand. In no event, however, shall the charges permitted under this Section
5 or elsewhere in this Lease, to the extent the same are considered to be
interest under applicable law, exceed the maximum lawful contract rate of
interest.

6.       SECURITY DEPOSIT:  [Intentionally omitted.]

7.       LANDLORD'S OBLIGATIONS:

         a.    SERVICE. Provided no Event of Default exists by Tenant, Landlord
shall use reasonable efforts to furnish to Tenant (1) water (hot and cold) at
those points of supply provided for general use of tenants of the Building; (ii)
heated and refrigerated air conditioning as appropriate, at such times as
Landlord normally furnishes these services to all tenants of the Building, and
at such temperatures and in such amounts as are reasonably considered by
Landlord to be standard; and on such other days or after business hours periods
as Tenant requires provided Tenant shall be charged for heating and air
conditioning on such other days or after business hours periods at an initial
rate of $50.00 per hour of use, to be increased from time to time by the
amounts, if any, that Landlord's costs of providing such services are increased
by the respective utility companies; (iii) janitorial service to the Premises on
weekdays other than holidays for Building-standard installations pursuant to the
Janitorial Specifications set forth in Exhibit "G" attached hereto (Landlord
reserves the right to bill Tenant separately for janitorial services which are
not described on said Janitorial Specifications) and such window washing as may
from time to time in Landlord's judgment be reasonably required; (iv) 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
elevators to be in operation at times other than during normal business hours
and on holidays; (v) replacement of Building-standard light bulbs and florescent
tubes; and (vi) electrical current during normal business hours other than for
computers, electronic data processing equipment, special lighting, and equipment

                                       5
<PAGE>

that requires more than 120 volts single phase, or other equipment whose
electrical consumption exceeds normal office usage. Landlord shall maintain the
common areas of the Building in reasonably good order and condition, except for
damage occasioned by Tenant, or its employees, agents or invitees. If Tenant
desires any of the services specified in this Section 7a. at any time other than
times herein designated (or as specified as normal business hours in the rules
and regulations attached hereto), Landlord shall supply such services to Tenant
upon the written request of Tenant delivered to Landlord before 1:00 p.m. on the
business day preceding such extra usage, and Tenant shall pay to Landlord the
cost of such services within ten days after Landlord has delivered to Tenant an
invoice therefor.

         b.    EXCESS UTILITY USE. If Tenant's requirements for or consumption
of electricity exceed the electricity to be provided by Landlord as described in
Section 7a., 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. 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 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 sole and absolute judgment, the
same are necessary and shall not cause permanent damage or injury 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 (other than general office machines, excluding computers and
electronic data processing equipment) in the Premises which require additional
air conditioning capacity above that provided by the Building standard system,
Tenant shall pay the costs of additional air conditioning installation and
operating costs; provided that the installation of any additional air
conditioning shall be subject to Section 8a.

         c.    DISCONTINUANCE. Landlord's obligation to furnish utility services
under Section 7a. shall be subject to the rules and regulations of the supplier
of such services and governmental rules and regulations. Landlord may, upon not
less than thirty (30) days prior written notice to Tenant, discontinue any such
services to the premises, provided Landlord first arranges for a direct
connection thereof through the supplier of such service. Tenant shall, however,
be responsible for contracting with the supplier of such services and for paying
all deposits for and costs relating to such services.

         d.    RESTORATION OF SERVICES; ABATEMENT. Landlord shall use
commercially reasonable efforts to restore any service that becomes interrupted;
however,  such  interruption  shall not render  Landlord  liable for any damages
caused thereby, be a constructive eviction of Tenant, constitute a breach of any
implied  warranty,  or entitle  Tenant to any  abatement of Tenant's  obligation
hereunder, including but not limited to Tenant's obligation to pay rent.

         e.    RESTROOM UPGRADE. Between the first and third anniversary of the
commencement of this Lease, Landlord will remodel the restrooms on Floors 2, 3
and 4 of the Building in a good faith effort to comply with the current
standards of accessibility set forth in the Americans with Disabilities Act.


                                       6

8.       IMPROVEMENTS; ALTERATIONS; REPAIRS; MAINTENANCE.

         a.    IMPROVEMENTS, ALTERATIONS. Except as otherwise specified in the
Lease or in any Exhibit hereto, improvements to the Premises shall be installed
at the expense of Tenant only in accordance with plans and specifications which
have been previously submitted to and approved in writing by Landlord. After the
initial Tenant improvements are made (if any), no alterations or physical
additions in or to the Premises may be made without Landlord's prior written
consent, which consent shall not be unreasonably withheld or delayed; provided,
however, that so long as Tenant gives Landlord prior written notice thereof,
Landlord's consent and approval shall not be required for any improvements or
alterations which are non-structural and cosmetic in nature and that cost less
than $5,000.00 per full floor of the Premises in the aggregate in any calendar
year. 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 consent shall not be
unreasonably withheld or delayed. All alterations, additions, or improvements,
(whether temporary or permanent in character, and including without limitation
all air-conditioning equipment and all other equipment that is in any manner
connected to the Building's plumbing system) made in or upon the Premises,
either by Landlord or Tenant, shall be Landlord's property at the end of the
Term and shall remain on the Premises without compensation to Tenant; provided,
however that if Tenant is not then in default hereunder and Tenant repairs any
damage caused by such removal, Tenant may remove its trade fixtures at the end
of the Term. Upon approving any improvement or alteration, Landlord shall also
advise Tenant as to whether it will require Tenant to remove such alteration or
improvement at the termination or expiration of this Lease. Approval by Landlord
of any of Tenant's drawings and plans and specifications prepared in connection
with any improvements in the Premises shall not constitute a representation or
warranty of Landlord as to the adequacy or sufficiency of such drawings, plans
and specifications, or the improvements to which they relate, for any use,
purpose, or condition, but such approval shall merely be the consent of Landlord
as required hereunder.

         b.    REPAIRS; MAINTENANCE. Tenant shall maintain the Premises in a
clean, safe, operable,  attractive  condition,  and shall not permit or allow to
remain any waste or damage to any portion of the Premises.  Landlord  shall,  at
its own expense (but subject to Landlord's right of reimbursement, in accordance
with Section 4 of this Lease, for maintenance  expenses  constituting  Operating
Expenses), maintain the exterior walls and the structure,  electrical,  plumbing
and  mechanical  systems of the  Building  provided  that Tenant shall repair or
replace,  subject to  Landlord's  direction and  supervision,  any damage to the
Building  or any of its  systems  caused  solely by Tenant or  Tenant's  agents,
contractors,  or invitees.  If Tenant fails to make such repairs or  replacement
within 15 days after the  occurrence of such damage,  then Landlord may make the
same at Tenant's  cost,  and shall be payable to Landlord  within ten days after
Landlord has delivered to Tenant an invoice therefore.

         c.    PERFORMANCE OF WORK. All work described in this Section 8 shall
be  performed  only by  contractors  and  subcontractors  approved in writing by
Landlord  which consent shall not be  unreasonably  withheld or delayed.  Tenant
shall cause all contractors and subcontractors to procure and maintain insurance
coverage  against  such  risks,  in such  amounts,  and with such  companies  as
Landlord may reasonably  acquire,  and to procure payment and performance  bonds
reasonably satisfactory to Landlord covering the cost of the work. All such work
shall be performed in accordance with all legal  requirements  and in a good and
workmanlike  manner so as not to damage the Premises,  the primary  structure or
structural  qualities of the Building,  or plumbing,  electrical lines, or other
utility transmission facility.

                                       7
<PAGE>

         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 ten days after Landlord has delivered notice
of the filing 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  elects  to  contest  such lien and if a
statutory  proceeding  exists for the  release  of the lien by the  posting of a
bond,  Tenant  shall  immediately  proceed  to obtain a release  of said lien in
accordance  with such  statute.  If Tenant  fails  either to timely pay the lien
amount  or  diligently  contest  such  lien and  deliver  the  required  bond or
security,  then  Landlord  may pay the  lien  claim  without  inquiry  as to the
validity  thereof,  and any amounts so paid,  including  expenses and  interest,
shall be paid by Tenant to Landlord within ten days after Landlord has delivered
to Tenant an invoice  therefore.  Nothing contained in this Lease will be deemed
the contest or  agreement  of  Landlord,  nor shall Tenant be deemed to have any
authority, to subject Landlord's interest in the Premises or the Building to the
imposition of any lien, or otherwise to liability, under any mechanics' or other
lien law.

9.       USE:

         a.    PERMITTED USE/COMPLIANCE WITH LAWS. Tenant shall continuously
occupy and use the Premises only for the Permitted Use and shall comply with all
laws,  orders,  rules  and  regulations  relating  to the  use,  condition,  and
occupancy  of the  Premises.  Tenant  shall  comply  with any  direction  of any
governmental  authority having  jurisdiction  over the Premises,  which shall by
reason of the nature of Tenant's use or occupancy  of the  Premises,  impose any
duty upon  Tenant or Landlord  with  respect to the  Premises  or the  occupancy
thereof.  Tenant  shall  not  do or  permit  anything  to be  done  which  would
invalidate  or increase the cost of any fire,  extended  coverage,  or any other
insurance  policy  covering the  Building.  Notwithstanding  the  foregoing  and
without  limiting the  remedies of Landlord for a violation of the  provision of
this Section 9a. Tenant shall promptly,  upon demand reimburse  Landlord for the
full  amount of any  additional  premium  charged  for such  policy by reason of
Tenant's  failure to comply with the  provision of this Section 9a. Tenant shall
not in any way  obstruct  or  interfere  with the  rights  of other  tenants  or
occupants  of the  Building,  or use or allow  the  Premises  to be used for any
illegal  purpose nor shall Tenant cause,  maintain or permit any nuisance in, on
or about the Premises.

         b.    HAZARDOUS MATERIALS. The Premises shall not be used for any use
which creates extraordinary fire hazards or results in an increased rate of
insurance on the Building or its contents or the storage of any Hazardous
Material (as defined below). Without limiting the foregoing, Tenant shall not
cause or permit any Hazardous Material to be brought upon, kept or used in or
about the Premises or Building or Appurtenant Facilities or the Land by Tenant,
its employees, agents, contractors or invitees which would have a material
adverse effect on the Building. As used herein, the term "Hazardous Material"
shall mean any hazardous or toxic substance, material or waste, including but
not limited to, those substances, materials and wastes now or hereafter listed
in the United States Department of Transportation Hazardous Materials Table or
by the Environmental Protection Agency as hazardous substances, or such
substances, materials and wastes that are or become regulated under any
applicable federal, state or local law, other than such substances, materials
and waste that are used, treated, stored or disposed of in normal quantities
that are consistent with the uses of the Premises for office and related uses,
provided all such actions are in accordance with all federal, state and local
statutes, rules, regulations and laws. Tenant expressly covenants that Tenant
will advise Landlord immediately upon learning that a Hazardous Material has
been brought upon the Premises or Building or Appurtenant Facilities or the

                                       8
<PAGE>

Land, whether or not caused or permitted by Tenant and regardless of who shall
have brought such Hazardous Materials thereon. If Tenant permits any Hazardous
Materials to be brought upon, kept or used in or about the Premises or Building
or Appurtenant Facilities or the Land, then Tenant shall take all steps
reasonably necessary to safeguard against their discharge and Tenant shall
indemnify, defend and hold Landlord harmless for any and all material claims,
judgments, damages, penalties, fines, costs, liabilities or losses, including
but not limited to, diminution in value of the Premises, or Building or
Appurtenant Facilities or the Land, damages for loss or restriction on use of
rentable or usable space or of any amenity in the Premises or Building or
Appurtenant Facilities or the Land, damages arising from adverse impact on
marketing the Premises or Building or Appurtenant Facilities or the Land, and
sums paid in settlement of claims, attorneys' fees, consulting fees and expert
fees, which solely arise during or after the Term as a result of such
contamination. This indemnification of Landlord by Tenant includes but is not
limited to costs incurred in connection with any investigation of sight
conditions or clean-up, remedial removal or restoration work required by any
federal, state or local government agency or political subdivision because of
Hazardous Material present in the Premises or Building or Appurtenant Facilities
or the Land, or the soil, or ground water on which the Building is located.
Without limiting the foregoing, if the presence of any Hazardous Material on the
Premises or Building or Appurtenant Facilities or the Land caused or permitted
by Tenant result in any contamination of the Premises or Building or Appurtenant
Facilities or the Land, Tenant shall, upon request by Landlord, promptly take
all actions at its sole expense that are necessary to return the Premises or
Building or Appurtenant Facilities or the Land to the condition existing prior
the introduction or exposure of any Hazardous Materials in the Premises or
Building or Appurtenant Facilities or the Land. The indemnity provision set
forth in this Section 9b. shall survive termination or expiration of this Lease.

10.      ASSIGNMENT AND SUBLETTING:

         a.    ASSIGNMENT OR SUBLEASE. Tenant shall not assign the Lease or
sublet the Premises or any part  thereof  without the prior  written  consent of
Landlord,  which  consent  shall not be  unreasonably  withheld.  Any  attempted
assignment  or sublease by Tenant in  violation of the terms and  conditions  of
this paragraph shall be void and of no effect.  If Tenant desires to assign this
Lease or sublet  the  Premises  or any part  thereof,  Tenant  shall  deliver to
Landlord  written  notice  thereof  (together with all the terms of the proposed
assignment or sublease,  the identity of the proposed  transferee and sufficient
financial  information  regarding the proposed  transferee to permit Landlord to
evaluate the  creditworthiness  thereof) at least 30 days in advance of the date
on which Tenant desires to make such assignment or sublease. Landlord shall have
7 days following  receipt of such notice and information  within which to notify
Tenant in writing that Landlord elects to (i) permit Tenant to assign this Lease
or sublet such space;  (ii) refuse to consent to such assignment or sublease and
to continue  this Lease in full force and effect as to the entire  Premises,  or
(iii)  terminate this Lease,  if Tenant desires to sublet all of the Premises or
terminate this Lease only as to the proposed  subleased  space,  if the proposed
subleased  space is less than the entire  Premises.  If Landlord fails to notify
Tenant of its  election  within such 7 day period,  Landlord  shall be deemed to
have elected option (ii) above.

         b.    CONSENT. The consent by Landlord to a particular assignment or
sublease shall not be deemed a consent to any other assignment or sublease. If
Landlord consents to a proposed assignment or sublease, then the proposed
transferee shall deliver to Landlord a written agreement whereby it expressly
assumes the Tenant's obligations hereunder; however, any transferee of less than
all of the space in the Premises shall be liable only for obligation under this
Lease that are properly allocable to the space subject to the assignment or
sublease, and only to the extent of the rent it has agreed to pay Tenant
therefor.

                                       9
<PAGE>


         c.    ADDITIONAL COMPENSATION. Tenant shall pay Landlord, immediately
upon receipt thereof,  fifty percent (50%) all  compensation  received by Tenant
(net of  reasonable  out of pocket  expenses  including  commissions  and tenant
improvements)  for an assignment or sublease that exceeds the Rent  allocable to
the portion of the Premises covered thereby.

         d.    CONTINUED LIABILITY. Tenant shall, despite any permitted
assignment or sublease, remain directly and primarily liable for the performance
of all the covenants,  duties, and obligations of Tenant hereunder, and Landlord
shall be permitted to enforce the provisions of this Lease against Tenant or any
assignee or sublessee  without  demand upon or proceeding in any way against any
other person.

         e.    TRANSFER OF CONTROLLING INTEREST. If Tenant is not a public
company that is registered on a national  stock  exchange or that is required to
register its stock with the  Securities  and Exchange  Commission  under Section
12(g) of the Securities and Exchange Act of 1934,  then any change in a majority
of the voting rights or other controlling rights or interests of Tenant shall be
deemed an assignment for the purposes hereof.

11.      INSURANCE; WAIVERS, SUBROGATION; INDEMNITY:

         a.    INSURANCE. Tenant shall at its expense procure and maintain
throughout the Term the following insurance policies: (i) comprehensive general
liability insurance in amounts of not less than a combined single limit of
$1,000,000.00, insuring Tenant, Landlord, and Landlord's agents 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, Building, Appurtenant
Facilities or Land, (ii) contractual liability insurance coverage sufficient to
cover Tenant's indemnity obligations hereunder, (iii) if Tenant operates owned,
leased, hired or non-owned vehicles on the Premises, comprehensive automobile
liability insurance at a limit of liability not less than $1,000,000.00 combined
bodily injury and property damages, (iv) insurance covering the full value of
Tenant's property and improvements, and other property (including property of
others), in the Premises and, (v) 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
certificates of such insurance and such other evidence satisfactory to Landlord
of the maintenance of all insurance coverage required hereunder, and Tenant
shall obtain a written 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. All such insurance policies shall be in form, and issued by
companies, reasonably satisfactory to Landlord. Tenant may carry such insurance
under a blanket policy, provided such insurance has a landlord's protective
liability endorsement attached thereto. If Tenant fails to procure and maintain
said insurance, Landlord may, but shall not be required to procure and maintain
same, but at the expense of Tenant. No policy shall be cancelable or subject to
reduction of coverage except after thirty (30) days prior written notice to
Landlord.

         b.    WAIVER; NO SUBROGATION. Landlord shall not be liable to Tenant or
those claiming by, through, or under Tenant for any injury to or death of any
person or persons or the damage to or theft, destruction, loss, or loss of use
of any property (a "Loss") caused by casualty, theft, fire, or third parties, or
by any other matter beyond the reasonable control of Landlord, or for any injury
or damage or inconvenience which may arise through repair or alteration of any
part of the Building, or failure to make repairs, or from any other cause,
except if such Loss is caused by Landlord's gross negligence or willful
misconduct. Tenant waives any claim it might have against Landlord for any
damage to or theft, destruction, loss, or loss of use of any property, to the

                                       10
<PAGE>


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 is required to be insured against under
the terms hereof, regardless of whether the negligence or fault of the other
party caused such loss. Tenant shall cause its property insurance carrier to
endorse all applicable policies waiving the carrier's rights of recovery under
subrogation or otherwise against the Landlord.

         c.    INDEMNITY. Subject to Section 11b., Tenant shall defend,
indemnify, and hold harmless Landlord and its partners,  officers, employees and
agents  from and against all  claims,  demands,  liabilities,  causes of action,
suits,  judgments,  and expenses (including  reasonable attorneys' fees) for any
Loss arising from Tenant's  failure to perform its obligations  under this Lease
(other than a Loss arising from the sole or gross  negligence of Landlord or its
agents),  even though caused or alleged to be caused by the joint,  comparative,
or concurrent negligence or fault 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  11b.,
Landlord shall defend,  indemnify and hold harmless  Tenant and its officers and
agents  from and against all  claims,  demands,  liabilities,  causes of action,
suits,  judgments,  and expenses (including  reasonable attorneys' fees) for any
Loss from Landlord's  failure to perform its obligations under this Lease (other
than a Loss arising from the sole or gross  negligence of Tenant or its agents),
even  though  caused  or  alleged  to be caused by the  joint,  comparative,  or
concurrent negligence or fault of Tenant 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 Tenant or its agents. This indemnity provision shall survive
termination or expiration of this Lease.

12.  SUBORDINATION; ATTORNMENT; NOTICE TO LANDLORD'S MORTGAGEE:

         a.    SUBORDINATION AND ATTORNMENT. This Lease shall be subordinate to
any deed of trust, mortgage, or other security instrument (a "Mortgage"), that
now or hereafter covers all or any part of the Premises (the mortgagee under any
Mortgage is referred to herein as "Landlord's Mortgagee"), provided that
Landlord's Mortgagee agrees not to disturb Tenant's rights under this lease
while Tenant is not of default of its obligations hereunder. Subject to the
foregoing; 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, or otherwise, upon such party's request, and shall execute such
agreements confirming such attornment as such party may reasonably request
provided that in such agreement the succeeding party agrees not to disturb
Tenant's right to possession of the Premises so long as Tenant is not in default
hereunder. In the event of such request and upon Tenant's attornment as
aforesaid, Tenant will automatically become the tenant of the successor to
Landlord's interest without change in the terms of provisions of this Lease;
provided, however, that such successor to Landlord's interest shall not be bound
by (a) any payment of Rent for more than one month in advance (except
prepayments for security deposits, if any), (b) any amendments or modifications
of this Lease made without the prior written consent of Landlord's Mortgagee if
Tenant was advised on the interest of same, or (c) any credits, offsets,
defenses or claims which Tenant may have against Landlord.

         c.    NOTICE TO LANDLORD'S MORTGAGEE. Tenant shall not seek to enforce
any remedy it may have for any default on the part of the 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.

                                       11
<PAGE>

         d.    CERTIFICATES REQUESTED BY LANDLORD'S MORTGAGEE. From time to
time,  Tenant shall furnish to any Landlord's  Mortgagee  within 10 days after a
request therefor,  such reasonable  estoppel  certificates,  non-disturbance and
attornment  agreements,  or  other  certificates  as  Landlord's  Mortgagee  may
reasonably request.

13.      RULES AND REGULATIONS:

         Tenant shall comply with the rules and regulations of the Building
which are attached hereto as Exhibit B. 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 generally 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 its employees, agents, and invitees. Landlord shall not
be responsible to Tenant for the failure or refusal by any tenant or other
person in the Building to comply with the rules and regulations established by
Landlord.

14.      CONDEMNATION:

         If all of the Premises are taken by exercise of the power of eminent
domain (or conveyed by Landlord in lieu of such exercise) this Lease will
terminate on a date (the "termination date") which is the earlier of the date
upon which the condemning authority takes possession of the premises or the date
on which title to the premises is vested in the condemning authority. If more
than 25% of the rentable area of the Premises is so taken, Tenant will have the
right to cancel this Lease by written notice to Landlord given within 20 days
after the termination date. If less than 25% of the rentable area of the
premises is so taken, or if the Tenant does not cancel this Lease according to
the preceding sentence, the monthly rent will be abated in the proportion of the
rentable area of the premises so taken to the rentable area of the premises
immediately and before such taking and Tenant's share will be appropriately
recalculated. If 25% or more of the Building or the Land is so taken, Landlord
may cancel this lease by written notice to Tenant given within 30 days after the
termination date. In the event of any such taking, the entire award will be paid
to Landlord and Tenant will have no right or claim to any part of such award;
however, Tenant will have the right to assert a claim against the condemning
authority in a separate action, so long as Landlord's award is not otherwise
reduced, for Tenant's moving expenses and leasehold improvements owned by
Tenant. Landlord shall provide notice to Tenant promptly upon receipt of notice
of proposed condemnation from any condemning authority.

15.      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 sixty (60) 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, prior to the final year of
the original term or the final year of any renewal term which is then in effect,
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
120 days after the date of the commencement of repairs, the Tenant may terminate
this Lease by delivering written notice to Landlord of its election to terminate
within 30 days after Damage Notice has been delivered to Tenant.  If Tenant does

                                       12
<PAGE>


not terminate this Lease, then (subject to Landlord's rights under Section 15c.)
Landlord  shall  repair the  Building  or the  Premises,  as the case may be, as
provided below, and Basic Rental and Excess Operating Expense for the portion of
the Premises rendered untenantable by the damage shall be abated on a reasonable
basis from the date of Casualty  until the  completion  of the  repairs,  unless
Tenant  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  during the final year of the original  term,  or during the final
year of the  renewal  term under this  Lease,  and  Landlord  makes a good faith
determination that restoring the Premises would be uneconomical,  of if Landlord
is  required  to pay any  insurance  proceeds  arising  out of the  Casualty  to
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  Rental  and  Excess  Operating  Expense
hereunder shall be abated as of the date of the Casualty. If the Casualty occurs
within the last 120 days of the lease term (or of any renewal term),  Tenant may
terminate this Lease upon written notice to Landlord.

         d.    REPAIR OBLIGATION. If neither party elects to terminate this
Lease,  in an instance  where such party is permitted  to so elect,  following a
Casualty,  then Landlord  shall,  within a reasonable  time after such Casualty,
commence  to  repair  the  Building  and the  Premises  and shall  proceed  with
reasonable  diligence  to restore the Building and Premises 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 part
of the furniture, equipment or fixtures 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 or the insurance  proceeds  actually  received by Landlord
for the Casualty in question.

16.      TAXES:

         Tenant shall be liable for all taxes levied or assessed against
personal property, furniture, or fixtures placed by Tenant, or above building
standard tenant improvements, in the Premises and all taxes relating to the
operation of Tenant's business in the Premises including, without limitation,
all withholding taxes and sales and use taxes. 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
above building standard improvements, and Landlord elects to pay the taxes based
on such increase, then Tenant shall pay to Landlord, upon demand, that part of
such taxes for which Tenant is primarily liable hereunder.

17.      EVENTS OF DEFAULT:

         Each of the following occurrences shall constitute an "Event of
Default":

         a.    Tenant's failure to pay Rent from Tenant to Landlord under the
Lease when due;  provided  that  Landlord  shall not exercise any remedies  with
respect to such Event of Default unless the same remains uncured for a period of
five (5) days after  Landlord has delivered  written  notice  thereof;  provided
further,  however,  that  Landlord may exercise  any such  remedies  without any
obligation  of Landlord to give any notice if Landlord has given Tenant  written
notice  under  this  Section  17a.  on more than two (2)  occasions  during  the
12-month interval preceding such failure by Tenant;

         b.    Tenant's failure to perform, comply with, or observe any other
agreement or obligation of Tenant under this Lease; provided that Landlord shall
not exercise any remedies with respect to such Event of Default unless the same

                                       13
<PAGE>

remains uncured for a period of 30 days after Landlord delivers to Tenant
written notice thereof;

         c.    The filing of a petition by or against Tenant (the term "Tenant"
shall include, for the purpose of this Section 17c., any guarantor of the
Tenant's obligations hereunder) (i) in any bankruptcy or other insolvency
proceeding; (ii) seeking any relief under any state or federal debtor relief
law; (iii) for the appointment of a liquidator or receiver for all or
substantially all of Tenant's property or for Tenant's interest in the Lease; or
(iv) for the reorganization or modification of Tenant's capital structure;
provided, however, if such petition is filed against Tenant, then such filing
shall not be an Event of Default unless Tenant fails to have proceedings
initiated by such petition dismissed within 60 days after the filing thereof;
and provided further, however, that an event described in this Section 17c.
shall not constitute an Event of Default if applicable law provides that such
event cannot be the basis of a default hereunder;

         d.    Tenant shall vacate or abandon any portion of the Premises unless
Tenant continues to pay its rent and perform its other obligations under this
Lease in a timely manner.

         e.    The  admission  by Tenant  that it cannot  meet its  obligations
as they  become  due or the  making by Tenant of an assignment for the benefit
of its creditor; or

         f.    Any  representation  or warranty made by Tenant,  or made by any
guarantor of Tenant's  obligations  hereunder,  was materially false or
inaccurate when made.

18.      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 (i) all Rent accrued
hereunder through the date of termination, (ii) all amounts due under Section
19a., and (iii) 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 par annum rate equal to the "Prime Rate" as published on the date this
Lease is terminated by the Wall Street Journal in its listing of "Prime Rate" as
published on the date this Lease is terminated by the Wall Street Journal in its
listing of "Money Rates", minus (b) the then present fair rental value of the
Premises for such period, similarly discounted; or

         b.    Terminate Tenant's right to possession of the Premises without
terminating this Lease by giving written notice thereof to Tenant, in which
event Tenant shall pay to Landlord (i) all Rent and other amounts accrued
hereunder to the date of termination of possession, (ii) all amounts due from
time to time under Section 19a., and (iii) all Rent and other sums required
hereunder to be paid by Tenant during the remainder of Term, diminished by any
net sums thereafter received by Landlord through reletting the Premises during
such period; provided, however, that Landlord shall have no obligation to relet
the Premises and Landlord shall have no obligation 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.
Notwithstanding the foregoing, Landlord shall have the obligation to make good
faith efforts to mitigate damages. 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 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,

                                       14
<PAGE>

all actions taken by Landlord to exclude or dispossess Tenant of the Premises
shall be deemed to be taken under this Section 18b. If Landlord elects to
proceed under this Section 18b, it may at any time elect to terminate this Lease
under Section 18a.

         c.    Additionally, unless otherwise required by applicable law,
Landlord may withhold  notice,  enter upon the Premises and alter locks or other
security  devices at the Premises to deprive  Tenant,  its officers,  employees,
agents,  invitees,  licensees and all other  occupants,  of access thereto,  and
Landlord  shall  not be  required  to  provide  a new key or right of  access to
Tenant.

19.      PAYMENT BY TENANT; NON-WAIVER:

         a.    PAYMENT BY TENANT. Upon any Event of Default, Tenant shall pay to
Landlord all reasonable and necessary costs incurred by Landlord (including
court costs at all trial and appellate levels and reasonable attorneys' fees and
expenses, regardless of whether suit is filed) in (i) obtaining possession of
the Premises, (ii) removing and storing Tenant's or any other occupant's
property, (iii) repairing, restoring, altering, remodeling, or otherwise putting
the Premises into condition acceptable to a new tenant, (iv) if Tenant is
dispossessed of the Premises and this Lease is not terminated, reletting all or
any part of the Premises (including brokerage commissions, cost of tenant finish
work, and other costs incidental to such reletting), (v) performing Tenant's
obligations which Tenant failed to perform, and (vi) enforcing, or obtaining
advice of its rights, remedies, and recourse arising out of the Event of
Default.

         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 either party of any violation or breach of any of the terms contained
herein shall waive either party's rights regarding any future violation of such
term or violation of any other term.

20.      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 equipment, fixtures, furniture, improvements and other personal
property of Tenant situated on the Premises from time to time, and all proceeds
therefrom (the "Collateral") which security interest may be enforced by Landlord
in any manner provided by law, including, without limitation, under and in
accordance with the Uniform Commercial Code in effect in the state in which the
Building is located (the "UCC"). The Collateral shall not be removed from the
Premises without the consent of Landlord until all obligations of Tenant have
been fully performed. Tenant grants to Landlord a power of attorney to execute
and file any financing statement necessary to perfect Landlord's security
interest under this Section 20, which power is coupled with an interest and
shall be 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. Without excluding any other manner of giving Tenant any required
notice, any requirement of reasonable notice to Tenant of Landlord's intention
to dispose of any Collateral pursuant to the enforcement of such security
interest shall be satisfied if such notice is given at least ten (10) days
before the time of any such disposition. Contemporaneously with the execution of
this Lease (and if requested hereafter by Landlord), Tenant shall execute and
deliver to Landlords such UCC Financing Statement in sufficient form so that
when properly filed, the security interest hereby given shall thereupon be
perfected. If requested hereafter by Landlord, Tenant shall also execute and
deliver to Landlord UCC Financing Statement Change instruments in sufficient
form to reflect any proper amendment of, modification in or extension of the
aforesaid contract lien and security interest hereby granted. Landlord shall, in

                                       15
<PAGE>

addition to all of its rights hereunder, also have all the rights and remedies
of a secured party under the UCC.

21.      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 the same is made 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 thereon in good repair and condition, reasonable wear
and tear (and condemnation and fire or other casualty damage not caused by
Tenant, as to which Sections 14 and 15 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 trade fixtures and all
unattached furniture and personal property placed in the Premises by Tenant (but
Tenant shall not remove any such item which was paid for, in whole or in part,
by Landlord), and shall remove such alterations, additions, improvements, trade
fixtures, equipment, and furniture as Landlord has designated in advance
pursuant to Section 8(a) hereof. Tenant shall repair all damage caused by such
removal. All items not so removed shall be deemed to have been abandoned by
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 21 shall survive the end of the
Term.

22.      HOLDOVER:

         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 and
remedies to which Landlord may be entitled for such holding over, Tenant shall
pay, in addition to the other Rent, a daily Basic Rental equal to the greater of
(a) 150% of the daily Basic Rental payable during the last month of the Term, or
(b) the prevailing rental rate in the Building for similar space. In the event
of any unauthorized holding over, Tenant shall be liable to Landlord against all
claims made by any other tenant or prospective tenant against Landlord resulting
from delay by Landlord in delivering possession of the Premises to such other
tenant or prospective tenant.

23.      CERTAIN RIGHTS RESERVED BY LANDLORD:

         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; for such purposes, to enter upon the
Premises upon reasonable notice to Tenant 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; and to change the arrangement and location of entrances and
passageways, doors, and doorways, corridors, elevators, stairs, rest rooms, 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, including without limitation
searching all persons entering or leaving the Building; 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
Saturdays, 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 which may include by way
of example, but not of limitation, that persons entering or leaving the
Building, whether or not during normal business hours, identify themselves to a

                                       16
<PAGE>

security officer by registration or otherwise and that such persons establish
their right to enter or leave the Building;

         c.       To change the name by which the Building is designated;

         d.       To enter the Premises at all reasonable hours to inspect same
to  assure  Tenant's  compliance  with  its  obligations  hereunder  to show the
Premises  to  prospective  purchasers,  lenders,  or tenants  and to perform all
services,   maintenance  and  repairs  required  to  be  performed  by  Landlord
hereunder; and

         e.       Landlord shall use good faith efforts in connection with all
of the foregoing to minimize  interference with Tenant's business at its
premises.

         24.      MISCELLANEOUS:

         a.    LANDLORD TRANSFER. Landlord may transfer 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
accruing after the date of such transfer, provided that the assignee assumes
Landlord's obligations hereunder accruing after the date of such transfer in
writing except that such assignee shall not be bound by, or assume any liability
with respect to (a) any payment of Rent for more than one month in advance
(except pre-payments for security deposits, if any), (b) any amendments or
modifications of this Lease made without prior written consent of Landlord's
mortgagee if Tenant was advised on the interest of same, or (c) any credits,
offsets, defenses, or claims which Tenant may have against Landlord.

         b.    LANDLORD'S DEFAULT AND LIABILITY. If Landlord fails to perform
any of its  obligations  under  this  Lease,  Landlord  shall not be in  default
hereunder  and Tenant shall not have any rights or remedies  growing out of such
failure unless Tenant gives Landlord  written notice setting forth in reasonable
detail the nature and extent of such failure and such failure by Landlord is not
cured  within a ten (10) day period  following  delivery  of such notice or such
longer period therefore provided elsewhere in this Lease. If such failure cannot
reasonable  be cured within such ten (10) day period,  the length of such period
shall be  extended  for the period  reasonably  required  therefore  if Landlord
commences  curing such  failure  within such thirty (30) ten (10) day period and
continues  to take action to cure such  failure with  reasonable  diligence  and
continuity.  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 the Land.

         c.    FORCE MAJEURE. Other than Tenant's monetary obligations under the
Lease, whenever a period of time is herein prescribed for action to be taken by
either party hereto, such party shall not be liable or responsible for, and
there shall be excluded from the computation for any such period of time, any
delays due to strikes, riots, acts of God, shortages of labor or materials, war,
governmental laws, regulations, or restrictions, or any other causes of any kind
whatsoever which are beyond the control of such party. Any elimination or
shutting off of light, air or view by any structure which may be erected on
lands adjacent to the Building shall in no way affect this Lease or impose any
liability on Landlord.

         d.    CRIMINAL ACTS OF THIRD PARTIES. Any security guards or security
services provided by Landlord for the Building, Appurtenant Facilities or Land
are provided for the protection of Landlord's property. Tenant shall be
responsible for the protection of Tenant and Tenant's employees, agents,
contractors, invitees and licensees and their property against criminal acts of
third parties. Landlord shall not be liable to Tenant or any other party for

                                       17
<PAGE>

criminal acts of third parties. Tenant shall contact the local police and rely
on the local police for protection against criminal acts.

         e.    RELOCATION. Landlord shall have the option to relocate Tenant to
alternate space in the Building which alternate space shall be of comparable
size and value. If Landlord desires to relocate Tenant, Landlord shall give
Tenant not less than sixty (60) days prior written notice, which notice shall
include the date on which Tenant shall be required to relocate or move and the
space to which Tenant will be relocated. The reasonable cost and expense of
improving the alternate space with improvements substantially similar to those
located in the Premises and the reasonable cost of moving Tenant and Tenant's
property and equipment to the alternate space shall be paid by Landlord. If
Landlord relocates Tenant to alternate space, such alternate space shall for all
purposes be deemed to be the Premises hereunder.

         f.    BROKERAGE. Landlord and Tenant each warrant to the other that it
has not dealt with any broker or agent in connection with the negotiation or
execution of this Lease. Tenant and Landlord shall each indemnify the other
against all costs, expenses, attorney's 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.

         g.    ESTOPPEL CERTIFICATES. From time to time, Tenant shall furnish to
any party designated by Landlord, within 10 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
request.

         h.    NOTICES. All notices and other communications given pursuant to
this Lease  shall be in writing and shall be (i) mailed by first  class,  United
States Mail,  postage prepaid,  certified,  with return receipt  requested,  and
addressed  to the  parties  hereto at the address  specified  in the Basic Lease
Information,  (ii) hand delivered to the intended address, (iii) sent by prepaid
telegram,  cable,  facsimile  transmission,  or telex followed by a confirmatory
letter, or (iv) expedited delivery service with proof of delivery.  Notices sent
by certified  mail,  postage  prepaid,  shall be effective 3 business days after
being deposited in the United States Mail (or Canada Mail, as appropriate);  all
other 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.

         i.    SEVERABILITY.  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.

         j.    AMENDMENTS AND BINDING EFFECT. This Lease (including all Exhibits
hereto) constitutes the entire agreement between Landlord and Tenant and
supersedes all prior discussions and agreements of the parties relating to the
Premises and the Building. This Lease may not be amended except by instrument in
writing signed by Landlord and Tenant. Whenever any approval or consent of the
Landlord is required, such approval or consent shall not be binding on Landlord
unless expressed in writing and executed by an authorized representative of
Landlord. No provision of this Lease shall be deemed to have been waived by
either party unless such waiver is in writing signed by such party, 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 either party to insist
upon the performance by such party in strict accordance with the terms hereof.
The terms and conditions contained in this Lease shall inure to the benefit of

                                       18
<PAGE>

and be binding upon the parties hereto, and upon their respective successor 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 and Tenant's guarantors, no third party shall be
deemed a third party beneficiary hereof.

         k.    QUIET ENJOYMENT. Provided Tenant has performed all of the
material  terms and  conditions of this Lease to be performed by Tenant,  Tenant
shall  peaceably and quietly hold and have use and enjoyment of the Premises for
the Term, without hindrance from Landlord or any party claiming by, through,  or
under Landlord, subject to the terms and conditions of the Lease.

         l.    JOINT AND SEVERAL LIABILITY. If there is more than one Tenant,
then the obligations  hereunder  imposed upon Tenant shall be joint and several.
If there is a guarantor of Tenant's obligations hereunder,  then the obligations
hereunder  imposed  upon Tenant  shall be the joint and several  obligations  of
Tenant  and  such  guarantors  except  as  otherwise  provided  in the  Guaranty
Agreements executed by such guarantors.  Landlord need not first proceed against
Tenant before proceeding against such guarantors nor shall any such guarantor be
released  from its  guaranty  for any  reason  whatsoever,  except as  otherwise
provided in the Guaranty Agreement executed by such guarantor.

         m.    CAPTIONS.  The captions  contained in this Lease are for
convenience of reference  only, and do not limit or enlarge the terms and
conditions of this lease.

         n.    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.

         o.    NO OFFER.  The  submission  of the Lease to Tenant  shall not be
construed  as an offer,  nor shall  Tenant have any rights under this Lease
unless Landlord executes a copy of this Lease and delivers it to Tenant.

         p.    NO RIGHTS TO USE OF BUILDING NAME. Tenant shall have no interest
in, or rights to, the name of the Building. Landlord will have the right,
exercisable upon written notice and without liability to any tenant, to change
the name and street address of the Building. Tenant shall not engage in any
advertising mentioning the Building without the prior written consent of
Landlord. Landlord shall have the right to prohibit any advertising by Tenant
mentioning the Building that, in Landlord's opinion, tends to impair the
reputation of the Building or its desirability as a building for offices, and
upon written notice from Landlord, Tenant will refrain from or discontinue such
advertising.

         q.    TIME OF ESSENCE.  Except as provided in Section  24c.  hereof,
time is of the essence of this Lease and each and all of its provisions in which
performance is a factor.

         r.    AUTHORITY OF PARTIES. If Tenant is a corporation, limited
partnership, partnership, trust or other entity, each person executing this
Lease on behalf of said entity represents and warrants to Landlord that such is

                                   EXHIBIT "D"
                                     PARKING

         At the time of execution of the Lease, there is currently a parking
garage and parking area associated with the Building in which the Premises are
located (collectively referred to as the "Parking Area") which serves the
Building which includes the Premises.

         During the primary Term and any Renewal Term of this Lease Landlord
agrees to provide free parking, to the extent spaces are available, to Tenant
and its employees in the garage level and surface parking areas. The number of
spaces provided shall be consistent with Tenant's Proportionate Share. As of the
commencement of this Lease, there are 85 standard garage spaces and 55 standard
surface spaces; Tenant shall be entitled to 66 standard garage spaces and 43
standard surface spaces, subject to increase or decrease if Tenant's
Proportionate Share increases or decreases.

         Tenant will comply with all traffic, security, safety and other rules
and regulations promulgated from time to time by Landlord. Vehicles which are
unmoved or abandoned for more than three (3) days will be removed from the
Parking Area and impounded at Tenant's expense. Tenant shall be responsible for
any damage to the Parking Area caused by Tenant and Tenant's employees.

         Tenant shall at all times maintain with Landlord a list of permits held
by Tenant, which list shall be in form, scope and substance reasonably
satisfactory to Landlord, and shall identify the individual to whom a Permit has
been issued, the vehicle used by such individual and the license place number of
such vehicle.

         Tenant shall indemnify and hold harmless Landlord from and against all
claims, losses, liabilities, damages, costs and expenses (including, not limited
to, reasonably attorney's fees and court costs) arising or alleged to arise out
of Tenant's use of such parking spaces. In the event any of the parking spaces
reserved to Tenant are or become temporarily unavailable at any time or from
time to time throughout the Term, whether due to casualty beyond Landlord's
control, this Lease shall continue in full force and effect.

                                   EXHIBIT "E"
                                 RENEWAL OPTION

         Provided no uncured Event of Default exists, Tenant may renew this
Lease (the "Renewal Option") for one (1) additional period of five (5) years
(the "Renewal Term") on the same terms provided in the Lease (except as set
forth below), by delivering written notice of the exercise thereof (which notice
must be unconditional and shall be irrevocable) to Landlord not earlier than 270
days and not later than 180 days before the expiration of the initial Term. On
or before the commencement date of the Renewal Term, Landlord and Tenant shall
execute an amendment to this Lease extending the Term on the same general terms
provided in this Lease, except that (a) this Lease shall not be further
available for renewal and (b) the rental for the Renewal Term shall be
ninety-five percent (95%) of the "Market Rental Rate". The Market Rental Rate is
hereby defined to mean the then prevailing rents (including, without limitation,
those similar to the Basic Annual Rent and Additional Rent) payable on lease
transactions by tenants having a credit standing substantially similar to that
of Tenant, in buildings of comparable quality, condition and age, for space of
comparable quality, size, utility and location within the building as the
Premises, located within a three mile radius of the intersection of LBJ Freeway
and North Dallas Tollway in the City of Dallas and leased for a term
approximately equal to the Renewal Term. The Market Rental Rate will take into
consideration the tenant inducements, concessions, allowances and/or abatements
offered in the transactions considered in determining the Market Rental Rate.

         Tenant's rights under this Exhibit shall terminate if (i) this Lease or
Tenant's right to possession of the Premises is terminated in accordance with
the Lease, or (ii) Tenant fails to timely exercise its option under this
Exhibit, time being of the essence with respect to Tenant's exercise thereof.

                                   EXHIBIT "F"
                              RIGHT OF first offer
                              and expansion option

         1.    The term "Offer Expansion Space" as used herein shall mean the
first floor of the Building.  Prior to leasing to a third party any of the Offer
Expansion  Space,  Landlord  shall first  deliver to Tenant a written  statement
("Statement")  specifying the amount and location of such space, the anticipated
date of tender of  possession,  the rental rate  (including  any projected  rate
increases over the applicable  term), and other applicable  terms.  Tenant shall
have five (5)  business  days after  receipt of the  Statement  within  which to
notify  Landlord  in  writing  that it  elects  to lease  the  applicable  Offer
Expansion  Space (each such written notice is herein referred to as a "Notice").
If Tenant elects to lease the applicable  Offer Expansion Space within such five
(5) business day period, then Tenant's election shall be irrevocable.  If Tenant
elects not to lease the applicable  Offer Expansion  Space,  Landlord shall have
the right to lease such space to any other party; provided, however, that (i) if
such space if not leased within six months after the date of the  Statement,  or
(ii) if the economic  benefit  derived from any such lease with any  prospective
tenant is less than 90% of the economic benefit of the lease expansion  proposed
in the Statement, then Landlord shall again be required to comply with the terms
of this Exhibit prior to leasing all or any portion of the Offer Expansion Space
to other parties (or prior to Landlord itself occupying any portion of the Offer
Expansion  Space).  Failure by Tenant to notify  Landlord  within  such five (5)
business  day  period  shall be deemed an  election  by Tenant  not to lease the
applicable Offer Expansion Space. Subject to Paragraph 4 hereof,  Tenant's Right
of First Offer shall continue into the Renewal Term, if applicable.

         2.    If Tenant elects to lease the applicable Offer Expansion Space,
then such  space  shall be leased to Tenant  upon the terms and  conditions  set
forth in the Statement, subject to Section 3 below. Tenant shall, within 15 days
after Landlord's  written  request,  execute and return a lease amendment adding
the Offer  Expansion  Space to the  Premises  for all  purposes  under the Lease
(including  any  extensions  or  renewals)  and  confirming  the rent and  other
applicable  terms specified in the Statement.  If Tenant fails to timely execute
and return the required  lease  amendment,  then Tenant's  rights and Landlord's
obligations under this Rider shall expire and be of no further force or effect.

         3.    In exercising its right to lease the Offer Expansion Space,
Tenant  may  elect  to make  the  lease  term  for  the  Offer  Expansion  Space
coterminous with the Term; in which event, however, the Basic Rent for the lease
term for the Offer Expansion Space shall be adjusted as Landlord deems necessary
to ensure  that the  economic  benefit to be  received  by  Landlord  under such
coterminous  lease term shall be no less than the economic benefit that Landlord
would have received under a lease made in accordance with the terms specified in
the Notice. Tenant acknowledges and agrees that the application of the preceding
sentence may result in an adjustment  that  significantly  increases  Basic Rent
payable for the Offer Expansion Space over the coterminous lease term.

         4.    Notwithstanding any other provision or inference herein to the
contrary,  Tenant's  rights and  Landlord's  obligations  under this Rider shall
expire  and be of no  further  force  or  effect  on  the  earliest  of (i)  the
expiration or earlier  termination  of the term (whether the initial term or the
Renewal  Term) of the Lease,  (ii) an  assignment of this Lease by Tenant (other
than to an affiliate of Tenant), (iii) the subletting by Tenant of more than 50%
of the Agreed  Rentable  Area of the  Premises  (other than to an  affiliate  of
Tenant), or (iv) a default by Tenant under the Lease.

         5.    In addition to the foregoing, Landlord grants to Tenant an option
(the "Expansion  Option") to lease the Offer  Expansion Space (e.g.,  the entire
first floor of the  Building)  simultaneously  with its  exercise of its renewal
option set forth in Exhibit "E" hereof;  provided,  however, that Landlord shall
not be  obligated  to include in the Offer  Expansion  Space made  available  to
Tenant at the commencement of the Renewal Term any such space which is vacant as
of December 31, 2004. Tenant shall exercise its Expansion Option  simultaneously
with its  execution of the Renewal  Option.  If the Tenant does not exercise the
Expansion  Option,  Tenant shall have no further  option on the Offer  Expansion
Space; provided, however, that its Right of First Offer shall continue.
