2.02. LANDLORD'S WORK.

         (a) Landlord's Work includes all of the improvements to the Premises
which Landlord has agreed to make or perform, and Landlord has not agreed to
make or perform any other improvements or work to or on the Premises. Landlord
will demolish and remove the leasehold improvements currently located in the
Premises at its cost without reimbursement from Tenant and not to be paid for
out of the Tenant Improvement Allowance, except that the Tenant Improvement
Allowance will be applied to pay the applicable remodeling tax.

         (b) It is agreed that Landlord's Work shall be limited to contracting
for and coordinating the "build-out" of the Premises in accord with the plans
and specifications prepared by the space planner and/or architect engaged and
paid for by Tenant. Tenant shall cause its space planner/architect to prepare
detailed space plans for the Premises and provide same for review by Landlord
not later than five (5) business days after full execution and delivery of the
lease by Tenant and Landlord. Landlord shall have five (5) business days after
receipt of the plans to approve or disapprove them which approval shall not be
unreasonably withheld or delayed. At such time as the space plans are approved
by Landlord, Tenant's architect and engineer shall prepare final working
drawings for Landlord's Work. Tenant shall within five (5) days business after
receipt of Landlord's comments, submit such working drawing to Landlord for
review, and Landlord shall approve or disapprove such drawings within five (5)
business days after receipt. The working drawings shall include architectural,
mechanical and electrical drawings for all work shown on the approved space
plan. Tenant shall be solely responsible for assuring that the plans and working
drawings call for building work and materials which are fully in compliance with
all federal, state and local building requirements, including but not limited to
American Disabilities Act and building code requirements. Tenant shall defend,
save and hold Landlord harmless from any claims or causes of action of
whatsoever nature arising from the failure of the plans and working drawings to
meet such standards. Tenant shall have the right to select any architect, space
planner, and engineer it desires subject to Landlord's approval, which shall not
be unreasonably withheld. Landlord shall pay, without reimbursement from Tenant,
the costs incurred by it to review and approve plans and specifications. Tenant
shall not be in default thereunder if Landlord and Tenant fail to agree upon
such working drawings and no Tenant Delay shall result from any such failure.
However, if Landlord and Tenant do not agree upon such working drawings by
August 20, 1995, either Landlord or Tenant shall have the right to terminate
this Lease.

         (c) After approval by Landlord of the working drawings for the
Landlord's Work, Landlord shall submit the drawings to the appropriate
governmental body for plan checking and a building permit. Landlord, with
Tenant's cooperation, shall cause to be made any change in the working drawings
necessary to obtain the building permit. After final approval of the working
drawings, no further changes thereto may be made without the prior written
approval of both Landlord and Tenant which approval shall not be unreasonably
withheld or delayed.

         (d) Landlord shall perform Landlord's Work without any construction
management fees, in accordance with the Plans and Specifications, in a good and
workmanlike manner, and in compliance with all applicable laws, statutes,
ordinances, codes, rules and regulations, including without limitation zoning
and building ordinances and codes. Such work shall be completed as soon as
reasonably possible, subject to Force Majure. Tenant shall have the right to
approve all


                                       7





contractors, which approval shall not be unreasonably withheld, under
the following conditions: (1) Tenant must exercise such approval rights within
two (2) business days of Landlord's notice to Tenant of the proposed contractors
and (2) if Tenant fails to act on Landlord's notice of proposed contractors
within two (2) business days, the contractors shall thereby be approved.

         (e) Landlord shall pay the amount of the Tenant Improvement Allowance
toward the total cost (the "Construction Cost") of performing Landlord's Work.
In the event the Construction Cost shall exceed the amount of the Tenant
Improvement Allowance, such excess shall be paid by Tenant. Prior to
commencement of construction and installation of the Landlord's Work, Landlord
shall provide Tenant with an estimate of the Construction Cost. If such estimate
exceeds the Tenant Improvement Allowance, Tenant shall pay such excess to
Landlord in advance and such advance payment shall be used first in paying the
Construction Cost. Upon Substantial Completion, and provided that Landlord has
provided Tenant with a certificate for payment and a statement of the actual
Construction Cost, Tenant, within ten (10) days after its receipt of said
certificate for payment and statement of the actual Construction Cost, shall pay
Landlord any remaining portion of the Construction Cost to be paid by Tenant.

         (f) If any change in the Plans and Specifications, other than a change
required by Landlord unrelated to building code or other governmental standards,
or Tenant's request for any such change or the work required in processing such
request, causes a delay in Substantial Completion of Landlord's Work, then
notwithstanding anything to the contrary contained in this Lease, a Tenant Delay
shall be deemed to have occurred. Any such change shall be evidenced by a
written change order to be executed by Landlord and Tenant, which shall indicate
the work required, the cost thereof to Tenant, if any (which shall include a
$250 change order fee for each change order), and the Tenant Delay, if any,
which it is anticipated will be caused by such change or the request for such
change or the processing of such request. If any such change results in an
increase in the Construction Cost, and as a result thereof the Tenant
Improvement Allowance is or will be exceeded, or the amount by which the Tenant
Improvement Allowance is already estimated to be exceeded shall be increased,
the amount of such excess or increase in estimated excess, as the case may be,
shall be paid by Tenant to Landlord in advance. Landlord shall have three (3)
business days after its receipt of a change order request within which to
approve or disapprove the same. If any change order is disapproved a specific
reason shall be given. If Tenant elects to submit a revision to a change order
request which was not approved by Landlord, Landlord shall have three (3)
business days after its receipt of such revision within which to approve or
disapprove the same.

2.03. TENANT'S WORK. In addition to the work set forth in Section 2.02,
Tenant shall perform all of Tenant's Work. All of Tenant's Work shall be
performed in accordance with and shall be subject to the terms and conditions of
Article V. Tenant acknowledges and agrees that neither the Commencement Date nor
the payment of Rent shall be delayed for any period of time due to any delay in
completing Tenant's Work. Provided that Tenant's activities will not interfere
with or cause delay in construction and installation of Landlord's Work
(including, without limitation, any delay resulting from any work stoppage,
picketing, labor disruption or dispute), Landlord shall permit Tenant, its
agents, employees and representatives, access to the Premises for purposes of
performing Tenant's Work during the forty five (45))day period prior to the
Scheduled Commencement Date.

                                        8






2.04. CONDITION OF DEMISED PREMISES. Tenant agrees that neither
Landlord nor any agent, employee or representative of Landlord has made any
representations or warranties, express or implied, with respect to the Premises,
Landlord's Work, the condition thereof or the fitness thereof for Tenant's use,
except as may be expressly set forth in this Lease. By taking possession of the
Premises, Tenant shall be deemed to have accepted the Premises "AS IS" and "WITH
ALL FAULTS", subject only to defects in Landlord's Work which are specifically
identified in a written punch list signed by Landlord and Tenant prior to
Tenant's taking possession of the Premises. Notwithstanding the foregoing,
Landlord shall assign, if possible, to Tenant all contractor and supplier
warranties pertaining to Landlord's Work, which warranties are limited
specifically to the Demised Premises.

2.05. USE OF COMMON AREAS. Tenant is hereby granted the nonexclusive
license, in common with Landlord and the other tenants of the Building, to use
the Common Areas during the Term, subject to the terms and conditions of this
Lease.

any of the following at any time and from time to time:

         (a) Close off any of the Common Areas to whatever extent required for

any of the Common Areas or the accrual of any rights by any person or the public
to the Common Areas;

         (b) Change the size, use, shape, arrangement, location or nature of any
such Common Areas, or regulate or eliminate the use thereof;

         (c) Erect additional buildings or improvements on the Common Areas, or

for service to other parts of the Building above the ceiling surfaces, below the
floor surfaces, within the walls and in the central core areas; (ii) examine,
inspect and protect the Premises; (iii) make any repairs, replacements or
alterations which Landlord may be required to perform under this Lease, or which
Landlord may deem desirable for the Premises; (iv) exhibit the Premises to
prospective purchasers or Mortgagees; or (v) exhibit the same to prospective
tenants during the last six (6) months of the Term.

No exercise of any of the foregoing rights by Landlord shall give rise
to any claim for damages against Landlord, entitle Tenant to any abatement of or
offset against Rent, or constitute an actual or constructive eviction of Tenant;
provided that Landlord shall not exercise any of the foregoing

                                        9




rights in a manner which would materially deprive Tenant of the benefit and
enjoyment of the Premises for the Permitted Uses.

If Landlord's exercise of the foregoing rights unreasonably and materially
interferes with Tenant's use and enjoyment of any portion of the Premises, then
Tenant shall have the right to abate all Rent and Additional Rent Attributable
to such portion of the Premises for the period of such interference.

Landlord shall perform all routine (non-emergency) work and inspections
during normal business hours.

                                ARTICLE III.

Exhibit B.

3.02. DELAY IN POSSESSION. This Lease shall be deemed a binding obligation of
the parties regardless of when the Commencement Date occurs, and the Term shall
continue to run for the full length of the Term, unless sooner terminated as
herein provided. Landlord shall not be subject to any liability for any delay in
completion of Landlord's Work or delivery of possession of the Premises to
Tenant, Tenant's sole remedy for any such delay being the abatement of Rent
until the Commencement Date.

If the Commencement Date does not occur by December 31, 1995, either Landlord or
Tenant may terminate this Lease without penalty.

                                   ARTICLE IV.

simultaneously with the execution of this Lease, and each subsequent monthly
installment of Base Rent shall be due and payable in advance on the first day of
the month during the Term. If the Commencement Date is not the first day of a
calendar month, or if the last day of the Term is not the last day of a calendar
month, the payment of Base Rent due in the first or last calendar month of the
Term, as the case may be, shall be prorated at a daily rate.

4.02. OPERATING EXPENSES.

         (a) For each calendar year or portion thereof commencing January 1,
1997 and through the remainder of the Term, Tenant shall pay, as Additional
Rent, Tenant's Pro Rata Share of all increases in annual Operating Expenses,
above and beyond the Operating Expenses of calendar year 1996 which year shall
serve as the base for calculating Operating Expense increases, for the calendar
year (or portion thereof) in question, which Additional Rent shall be

                                       10






due and payable within ten (10) days after Landlord's invoice therefor,
accompanied by the statement described below. Landlord, at its option, may
require Tenant to pay monthly, in advance, together with the payment of Base
Rent, an amount equal to (i) Landlord's reasonable estimate of Tenant's Pro Rata
Share of increases in Operating Expenses for the current calendar year (which
estimate may be revised by Landlord from time to time), less the amount of any
increases in Operating Expenses previously paid by Tenant for such calendar
year, divided by (ii) the number of months remaining in such calendar year as of
the date Landlord's estimate (or any revision thereof) is given to Tenant.

         (b) Within one hundred fifty (150) days after the end of each calendar
year (or as soon thereafter as is practicable for Landlord), Landlord will
provide Tenant with a statement in reasonable detail of the Operating Expenses
payable by Tenant for such previous calendar year (with credit to Tenant for any
monthly estimated payments paid by Tenant). Tenant may audit a Landlord's
Operating Expenses once each year at Tenant's sole expense. If the total
payments made by Tenant exceed Tenant's Pro Rata Share of the actual increases
in Operating Expenses, such excess will be credited to the next monthly
installments due from Tenant. If Tenant's Pro Rata Share of the actual increases
in Operating Expenses exceeds the payments actually made by Tenant, Tenant shall
pay such deficiency, within ten (10) days after Landlord's delivery of the
statement. Tenant's obligation to pay any deficiency and Landlord's obligation
to refund any surplus shall survive the expiration of this Lease.

4.03. SECURITY DEPOSIT. The Security Deposit and, subject to the provisions of
Section 17.12, the Additional Security Deposit shall be held by Landlord as
security for the performance of Tenant's covenants and obligations under this
Lease, and it shall not be considered an advance payment of rental or a measure
of Landlord's damages in case of any default by Tenant. The Security Deposit and
Additional Security Deposit shall not bear interest to Tenant, and may be
commingled with Landlord's other funds. Following any Default, Landlord may,
from time to time, at its option, without prejudice to any other remedy, use the
Security Deposit to the extent necessary to remedy such Default. If any portion
of the Security Deposit is so used or applied, Tenant shall, within ten (10)
days after written notice from Landlord, deposit with Landlord an amount
sufficient to restore the Security Deposit to its original amount. Any remaining
balance of the Security Deposit shall be returned by Landlord to Tenant within
thirty (30) days after expiration of this Lease. If Landlord transfers its
interest in the Building, Landlord deliver the Security Deposit to the
transferee, and Tenant shall look solely to the new landlord for the return of
the Security Deposit, and the transferring Landlord shall be released from all
liability to Tenant for the return of the Security Deposit.

4.04. ADDITIONAL RENT. All remedies applicable to the nonpayment of Base Rent
shall apply to the nonpayment of Additional Rent.

4.05. NO OFFSET. Base Rent and Additional Rent shall be paid without demand,
setoff, deduction or counterclaim of any nature whatsoever. Tenant agrees that
any claims against Landlord may be pursued only in an independent action against
Landlord, subject to the limitations contained in this Lease.

                                       11




4.06. INTEREST/LATE FEE. All payments required to be made by Tenant under this
Lease which are not paid within five (5) days after the due date shall bear
interest at a rate equal to the lesser of eighteen percent (18%) per annum, or
the highest rate allowed by law, from the due date of each payment until the
date actually paid by Tenant. In addition to interest and all other amounts due
to Landlord hereunder, Tenant, if required by and upon demand of Landlord, will
pay Landlord a "late fee" equal to five percent (5%) of any payment which has
not been paid within thirty (30) days after its due date.

4.07. RENTAL TAXES. If at any time during the Term, under federal, state or
local law a tax, charge, capital levy or excise on rents (fixed, guaranteed or
additional) or other tax (except income tax) shall be levied against Landlord on
account of the Base Rent or Additional Rent payable herein, such tax, charge,
capital levy or excise on rents or other such tax shall be paid by Tenant, or
reimbursed to Landlord by Tenant, if such amounts are initially paid by
Landlord.

                                   ARTICLE V.
                                   ALTERATIONS

5.01. ALTERATIONS.

         (a) Tenant may not make any Alterations without the prior written
consent of Landlord, which consent shall not be unreasonably withheld, unless
the Alteration is "material", in which event Landlord may withhold its consent
in its sole discretion. Any Alteration affecting the structure of the Building
or the electrical, mechanical or plumbing systems of the Building or requiring
penetration of the roof, walls or floor of the Building or the Premises, and any
other Alteration which is expected to cost in excess of $30,000, shall be
considered a "material" Alteration. Alteration work undertaken by Tenant on the
roof of the Building and parking garage is governed by Exhibit D.

         (b) If requested by Landlord, Tenant shall provide to Landlord, before
commencement of any Alteration or delivery of any materials to be used therefor,
complete and final plans and specifications, names and addresses of contractors,
copies of contracts, necessary permits and licenses, and an indemnification in
such form and amount as may be reasonably satisfactory to Landlord or a
performance bond executed by a commercial surety reasonably satisfactory to
Landlord, in an amount equal to 120% of the estimated cost of the Alterations.
Tenant shall pay the cost of all such Alterations, and also shall pay Landlord a
supervision fee equal to five percent (5%) of the cost of such Alterations,
which fee shall be payable in advance prior to commencement of such Alterations,
based on the estimated cost thereof, with an adjustment to be made upon
completion of such Alterations based on the actual cost thereof. Upon completion
of any Alteration, Tenant shall, if requested by Landlord, furnish Landlord with
"as built" plans and specifications, sworn construction cost statements, and
full and final waivers of liens and receipted bills covering all labor and
materials expended and used in connection with such Alterations. Any Alterations
made by Tenant shall comply with all insurance requirements and all laws,
ordinances, rules and regulations of all governmental authorities and shall be
constructed in a good and workmanlike manner, in accordance with the plans and
specifications approved by Landlord, which approval shall not be unreasonably
withheld, and shall be prosecuted diligently to completion. Tenant shall permit
Landlord to inspect construction operations in connection with any Alterations.
Landlord's approval of any plans, specifications

                                       12






or working drawings for Alterations shall create no responsibility or liability
on the part of Landlord for their completeness, design sufficiency, or
compliance with all laws, rules and regulations of governmental agencies or
authorities. Tenant shall indemnify, defend and hold Landlord harmless from and
against any and all claims, losses, damages, liabilities, costs and expenses of
any kind and description (including without limitation mechanics' liens and
attorneys' fees and legal costs) which may arise out of or be connected in any
way with such Alterations; such indemnity shall survive the expiration or
termination of this Lease. All Alterations shall be done only by contractors and
subcontractors approved by Landlord which approval shall not be unreasonably
withheld or delayed, and at such time and in such manner as Landlord may from
time to time reasonably designate. All Alterations shall be done in such a
manner as to avoid labor disputes. Tenant shall pay the cost of repairing any
damage caused to the Premises, the Building or the Project in connection with
any Alterations. If any Alteration is material, or if otherwise required by
Landlord in its reasonable discretion, Tenant shall maintain during construction
of any Alterations, a policy of builder's risk insurance in an amount equal to
the completed value of all improvements under construction, which policy shall
be in form and substance satisfactory to Landlord and shall name Landlord and
its Mortgagee as loss payees thereunder, as their interests may appear, and
Tenant shall furnish a certificate thereof to Landlord prior to commencing such
Alterations. This provision shall not apply to the work contemplated in Section
2.02.

         (c) All Alterations (other than Non-Removable Alterations) shall, at
the election of Landlord, be removed by Tenant at its expense before the
expiration of the Term, unless otherwise agreed by Landlord at the time of
Landlord's consent to such Alteration. If requested by Tenant at the time of
submission of plans and specifications to Landlord for review, Landlord shall
designate which Alterations (other than Non-Removable Alterations) Tenant may be
required to remove. Notwithstanding the foregoing, Tenant shall not be required
to remove any base building improvements, ceiling and above ceiling
improvements, light fixtures, mechanical, electrical, and plumbing systems,
fixtures and equipment ("Non-Removable Improvements"). Tenant shall have the
right to and Landlord may require Tenant, at its expense, to remove all
improvements other than Non-Removable Improvements, including all computer and
telecomununications equipment and related items, rooftop and garage mounted
communication systems, emergency power generator, Tenant installed air
conditioning system and Tenant's building signs. All Alterations which are not
required to be removed pursuant to this subsection (c) shall remain upon the
Premises and be surrendered therewith at the expiration or termination of the
Term as the property of Landlord. If Landlord requires the removal of any
Alterations (other than Non-Removable Alterations) Tenant shall, at its expense,
repair any damage to the Premises, the Building or the Project caused by such
removal and restore the Premises, the Building and the Project to their
condition prior to the construction of such Alterations.

5.02. MECHANICS' LIENS. If any mechanic's, materialman's or similar lien is
filed against the Premises, the Building or the Project as a result of any work
or act of Tenant, its contractors or agents, Tenant shall cause the discharge of
the lien within fifteen (15) days after the filing of the lien; or within such
fifteen (15) days after the filing of the lien Tenant shall file a bond, letter
of credit or other security sufficient to indemnify Landlord and the Project
from and against such lien, provided that Tenant diligently contests such lien
thereafter. If Tenant shall fail to cause the discharge of the lien, or to
provide such security against such lien, Landlord may, after five (5) days'
written notice to Tenant, but shall not be obligated to, bond or pay the lien or
claim for the 

                                       13







account of Tenant without inquiring into the validity thereof In such event,
Tenant shall promptly reimburse Landlord the amount so advanced or the costs and
expenses of such bond. Landlord shall have the right to post a notice in the
Premises disclaiming any liability for payment for any Alterations performed by
persons or entities other than Landlord or its contractors, and/or for any liens
arising in connection therewith, and Tenant agrees not to disturb any such
notice.

                                   ARTICLE VI.

Premises with electric current for lighting and normal use customarily provided
for similar buildings in the Dallas area. Tenant will not install or operate in

Landlord, which may condition such consent upon payment by Tenant for the cost
of any excess consumption or increase in capacity occasioned or necessitated by
the operation of said equipment or machinery. Tenant shall not install or

continue to provide its current level of security to the Building.

6.02. INTERRUPTION. Landlord does not warrant that any of the services referred
to in Section 6.01 will be free from interruption from causes beyond the
reasonable control of Landlord. Any such interruption of services shall never be
deemed an eviction or disturbance of Tenant's use or possession of the Premises,
or any part thereof, nor shall it render Landlord liable to Tenant for damages,
by abatement of rent or otherwise, nor shall it relieve Tenant from performance
of Tenant's obligations under this Lease provided Landlord agrees to use
reasonable and diligent efforts to promptly repair all equipment of machinery
and to restore said services.

6.03. RENT ABATEMENT; TERMINATION. Notwithstanding the provisions of Section
6.02, in the event that the Premises are rendered uninhabitable as a direct
result of Landlord's failure to provide any of the services set forth in Section
6.01 and such failure to provide any of the services set forth in Section 6.01
and such failure is not the result of any act of God, governmental authority or
other event of force majeure or the result of any action or inaction of Tenant,
then, if such uninhabitability continues for five consecutive days, rent shall
be abated in the proportion that the Premises are uninhabitable, and, if such
uninhabitability continues for 90 consecutive days for at least 50% of the
Premises, Tenant may terminate this Lease.

ABSOLUTE DISCRETION.

         (C) If Tenant requests Landlord's consent to a specific assignment or
subletting, Tenant will submit in writing to Landlord: (i) the name and address
of the proposed assignee or subtenant; (ii) a counterpart of the proposed
agreement of assignment or sublease executed by the assignee or subtenant; (iii)
information, satisfactory to Landlord in its sole discretion, as to the nature
and character of the business of the proposed assignee or subtenant, and as to
the nature of its proposed use of the space; (iv) banking, financial or other
credit information sufficient to

                                       19






enable Landlord to determine the financial responsibility and character of the
proposed assignee or subtenant; and (v) any other information reasonably
requested by Landlord. 

         (d) If Tenant proposes to assign this Lease, Landlord may, at its
option, upon written notice to Tenant given within thirty (30) days after its
receipt of the information described in Section 9.01(c), elect to recapture the
Premises and terminate this Lease. If Tenant proposes to sublease all or part of
the Premises for the remainder of the Term, Landlord may, at its option upon
written notice to Tenant given within thirty (30) days after its receipt of the
information described in Section 9.01(c), elect to recapture such portion of the
Premises as Tenant proposes to sublease and upon such election by Landlord, this
Lease shall terminate as to the portion of the Premises recaptured. Provided,
however, that the provisions of this subsection shall not apply to assignments
or sublettings to the entities set forth in subsection (f) of this Section. If a
portion of the Premises is recaptured, the Base Rent and Tenant's Pro Rata Share
shall be proportionately reduced based on the square footage of the recaptured
space, and Landlord and Tenant shall execute an appropriate amendment to this
Lease. Landlord may thereafter, without limitation, lease the recaptured portion
of the Premises to the proposed assignee or subtenant without liability to
Tenant.

         (e) If Landlord consents to any proposed assignment or sublease, then
(i) Tenant and any Guarantor shall remain primarily liable for all of Tenant's
obligations under this Lease, (ii) any assignee shall expressly assume in
writing all of Tenant's obligations hereunder, and any subternant shall agree in
writing to be bound by and subject to all of the terms and conditions of this
Lease, (iii) any rent or other consideration payable by the proposed assignee or
subtenant to Tenant in excess of amounts due under this Lease (after deducting
Tenant's reasonable and necessary expenses incurred in connection with such
assignment or subletting) shall be paid to Landlord, and not to Tenant, provided
that if Tenant assigns or sublets the Lease to a corporate affiliate of Tenant,
any rents or other consideration in excess of the amounts due under the Lease
(after deducting Tenant's reasonable and necessary expenses incurred in
connection with such assignment or subletting) shall be split evenly between
Landlord and Tenant, (iv) Tenant shall reimburse Landlord upon demand for all
costs and expenses, including reasonable attorneys' fees, incurred by Landlord
in connection with such assignment or sublease, and (v) all sublease rentals are
hereby assigned to Landlord as additional security for Tenant's obligations
under this Lease, and Tenant hereby authorizes and directs each subtenant to pay
such rent directly to Landlord, provided that Tenant shall have the license to
continue collecting such rent as long as no Default has occurred and is
continuing hereunder.

         (f) Notwithstanding the foregoing, without the consent of Landlord,
Tenant and shall have the right to assign this Lease or sublet the Premises to
any: (i) corporate successor of Tenant by merger or dissolution (ii) purchaser
of all or substantially all of Tenant's assets or (iii) corporate affiliate of
Tenant.

9.02. SUBORDINATION. Subject to Section 9.03, this Lease shall be subject and
subordinate to the lien of any present or future Mortgage, irrespective of the
time of execution or the time of recording of the Mortgage. Notwithstanding the
foregoing, any Mortgagee may, from time to time, by giving notice to Tenant,
elect that its Mortgage be subordinate to this Lease, which election shall be
effective upon the giving of such notice. Upon Landlord's request, from time to
time, Tenant shall confirm in a recordable written instrument, in such form as
may be

                                       20






required by any Mortgagee, that this Lease is so subordinate or so paramount to
the lien of such Mortgagee's Mortgage (as the Mortgagee may elect).

9.03. ATTORNMENT AND NON-DISTURBANCE. If the Premises is encumbered by a
Mortgage and the Mortgage is foreclosed, or if the Premises is sold pursuant to
foreclosure or by reason of a default under a Mortgage, the following shall
apply notwithstanding the foreclosure, the sale or the default; (i) Tenant shall
not disaffirm this Lease or any of its obligations under this Lease; and, (ii)
at the request of the Mortgagee or purchaser at the foreclosure or sale, Tenant
shall agree to perform this Lease for the benefit of the Mortgagee or purchaser,
provided that Tenant's right to continued use of the Premises is not adversely
affected thereby. Any Mortgage entered into by Landlord after the date of this
Lease shall provide, or Landlord shall obtain a separate agreement from the
Mortgagee, that in the event of a foreclosure of such Mortgage, or the
acquisition of the Premises, the Building or the Project by the Mortgagee by
deed in lieu of foreclosure, the Mortgagee, its successors and assigns, will not
terminate this Lease or inhibit Tenant's use of the Premises, provided that
Tenant is not in default hereunder and continues to perform all of its
obligations and pay all amounts due hereunder.

9.04. MORTGAGEE PROTECTION. Tenant agrees to give any Mortgagee by certified
mail, return receipt requested, a copy of any notice of default served upon
Landlord, provided that before such notice Tenant has been notified in writing
of the address of such Mortgagee. Tenant further agrees that if Landlord shall
have failed to cure such default within the time provided for in this Lease,
then any Mortgagee shall have an additional thirty (30) days within which to
cure such default; provided, however, that if such default cannot be cured with
diligence within that time, then such Mortgagee shall have such additional time
as may be necessary to cure such default so long as such Mortgagee has commenced
and is diligently pursuing the remedies necessary to cure such default
(including, without limitation, the commencement of foreclosure proceedings, if
necessary), in which event this Lease shall not be terminated or any Base Rent
or Additional Rent abated while such remedies are being diligently pursued. In
the event of the sale of the Building by foreclosure or deed in lieu thereof,
the Mortgagee or purchaser at such sale shall not be (i) personally liable for
any act or omission of Landlord occurring prior to such sale, (ii) bound by any
payment of Base Rent or Additional Rent made more than one month in advance,
(iii) bound by any modification, amendment or surrender of this Lease made
without such Mortgagee's consent, or (iv) responsible for the return of the
Security Deposit, except to the extent that such Mortgagee or purchaser actually
received the Security Deposit.

9.05. TRANSFER OF LANDLORD'S INTEREST. The term "Landlord" as used in this Lease
means only the owner for the time being or the Mortgagee in possession for the
time being of the Building. Each time the Building is sold, the selling Landlord
shall be released of all obligations and liability under this Lease arising from
and after the date title is transferred.

9.06. FINANCIAL STATEMENTS. Within ninety (90) days after the end of each
calendar year during the Term, Tenant shall provide to Landlord a copy of its
annual financial statements for the immediately preceding year. If Tenant has
otherwise had audited financial statements prepared for the year in question,
Landlord shall be provided with a copy of the audited financial statements;
however, if Tenant has not caused the financial statements to be audited, the
financial statements shall be certified as true and correct by the Chief
Financial Officer of Tenant. 

                                       21






Landlord and its agents shall keep all such financial information confidential
and shall not disclose any such information to any third party except as
otherwise required by law as necessary for financing purposes.

                                   ARTICLE X.
                                    CASUALTY

10.01. RENT ABATEMENT. If all or any portion of the Premises is damaged by fire
or casualty, and this Lease is not terminated pursuant to any provisions of this
Lease is not terminated pursuant to any provisions of this Lease, then Base Rent
and Tenant's obligation to pay Operating Expenses shall abate from the date of
the casualty in the proportion that the area of the portion of the Premises
rendered unusable for the Permitted Uses bears to the entire area of the
Premises. The abatement shall continue until the Premises, or the portion
thereof which shall have been damaged, is again usable for the Permitted Uses.

10.02. OPTIONS TO TERMINATE. This Lease shall not be terminated as a result of
fire or casualty except as follows:

         (a) Landlord shall have the option to terminate this Lease if the
Premises or the Building are damaged (i) by fire or other cause to such an
extent that, in Landlord's sole judgment, the damage cannot be substantially
repaired within one hundred and eighty (180)) days after the date of such
damage, or (ii) during the last year of the Term, unless Tenant has previously
obligated itself to an additional rental Term of at least five (5) years. This
option may be exercised by giving written notice of termination to Tenant within
forty-five (45) days following the casualty.

         (b) Provided the casualty has not been caused by Tenant or its agents,
employees, contractors, subtenants or invitees, Tenant shall have the option to
terminate this Lease if the damage is not substantially repaired within one
hundred eighty (180) days after the date on which Tenant gives written notice
of the casualty to Landlord, provided that such 180-day period shall be extended
by the period of any delay caused by Force Majeure. Such option to terminate
must be exercised, if at all, by written notice given by Tenant to Landlord
within ten (10) days after the expiration of such 180-day period.

If this Lease is terminated as provided in this Section, Base Rent and
Additional Rent shall be apportioned and paid to the date of such termination.
Except as expressly provided in this Section, Tenant hereby waives all rights to
terminate this Lease by reason of damage to the Premises as a result of fire or
other casualty pursuant to any presently existing or hereafter enacted statute
or other law.

10.03. OBLIGATION TO REBUILD. If all or any portion of the Premises is damaged
as provided in Section 10.01, and this Lease is not terminated as provided in
Section 10.02, then Landlord shall repair or rebuild the Premises to
substantially the same condition the Premises were in immediately prior to the
casualty, provided that Landlord's repair obligation shall include only those
tenant improvements originally included in Landlord's Work. Tenant shall, at its
sole expense, repair or replace all items of Tenant's Work, any Alterations and
Tenant's personal property. The repair or rebuilding shall be commenced within
a reasonable time after the

                                       22





casualty, subject to Force Majeure. Notwithstanding the foregoing, Landlord
shall not be obligated to expend any sums for repair or rebuilding which are
greater than the proceeds of any insurance policy actually received by Landlord
and made available to Landlord by any Mortgagee.

10.04. WAIVER OF SUBROGATION. Landlord and Tenant hereby release each other and
each other's officers, directors, partners, employees and agents from liability
or responsibility for any loss or damage to property covered by any property
insurance required to be carried by such party pursuant to this Lease or any
other property insurance actually carried by such party to the extent of the
limits of such policy. This release shall apply not only to liability and
responsibility of the parties to each other, but shall also extend to liability
and responsibility for anyone claiming through or under the parties by way of
subrogation or otherwise. This release shall apply even if the fire or other
casualty shall have been caused by the fault or negligence of a party or anyone
for whom a party may be responsible. This release shall not apply to loss or
damage unless the loss or damage occurs during the times the applicable
insurance policy contains a clause or endorsement to the effect that any release
shall not adversely affect or impair the policy or prejudice the right of the
insured to recover thereunder. Landlord and Tenant each agree that any property
insurance policies covering the Building or the Premises or their contents shall
include this clause or endorsement.

                                   ARTICLE XI.
                                  CONDEMNATION

11.01. TOTAL OR SUBSTANTIAL TAKING OF DEMISED PREMISES. If all of the Premises
shall be taken, except for a Taking for temporary use, this Lease shall be
terminated automatically as of the day prior to the Taking Date. If a
substantial part of the Premises, the Building or the Project shall be taken for
other than a temporary use, and such Taking renders the Premises unsuitable, in
Landlord's reasonable judgment, for the Permitted Uses, then either Landlord or
Tenant may terminate this Lease by giving notice to the other party within two
(2) months after the Taking Date, and such termination shall be effective as of
the day prior to the Taking Date.

11.02. ABATEMENT AND RESTORATION. If all or a portion of the Premises shall be
taken, except for a Taking for temporary use, and this Lease is not terminated
under Section 11.01, then (i) Base Rent and Tenant's Pro Rata Share shall be
reduced in the proportion that the area so taken bears to the entire area of the
Premises; and (ii) Landlord shall restore the remaining portion of the Premises
to the extent practical, to render it reasonably suitable for the Permitted
Uses, as reasonably determined by Landlord. Landlord shall not be obligated to
expend an amount greater than the amount of any Award actually received by
Landlord and made available to Landlord by any Mortgagee.

11.03. TAKING FOR TEMPORARY USE. If there is a Taking of all or part of the
Premises for temporary use, this Lease shall continue in full force and effect
without abatement of Base Rent or Additional Rent, and Tenant shall continue to
comply with Tenant's obligations under this Lease, except to the extent
compliance shall be rendered impossible or impracticable by reason of the
Taking. 

                                       23






11.04. DISPOSITION OF AWARDS. Tenant shall be entitled to any Award made for a
temporary Taking as described in Section 11.03, but only to the extent such
Award is attributable to periods included in the Term of this Lease and only on
the condition that Tenant continues to perform all of its obligations hereunder.
All other Awards arising from a total or partial Taking of the Premises or of
Tenant's leasehold interest awarded to Landlord or Tenant shall belong to and be
the property of Landlord without any participation by Tenant. Except as
otherwise expressly set forth in this Section 11.04, Tenant hereby waives any
rights it may have with respect to the loss of its leasehold interest in this
Lease and the Premises as a result of a Taking. The foregoing shall not prevent
Tenant from making a separate claim for relocation expenses and loss of Tenant's
personal property, to the extent allowed by law, as long as such claim is
separate and distinct from any claim of Landlord and does not diminish
Landlord's Award.

                                   ARTICLE XII.
                             INDEMNITY AND INSURANCE

12.01. INDEMNIFICATION. Tenant shall indemnify, defend and hold Landlord
harmless from and against all liabilities, losses, damages, claims, fines,
penalties, costs and expenses, including attorneys' fees and other legal costs,
which may be imposed upon, incurred by or asserted against Landlord by reason of
all or any of the following, except to the extent caused by the gross negligence
or willful misconduct of Landlord, its agents or employees or contractors, or by
the acts of other tenants, their agents, employees and contractors: (a) any
defect in the Premises or any part thereof; (b) any personal injury, death or
property damage occurring on the Premises; (c) any negligence on the part of
Tenant, its employees, agents, contractors, subtenants, licensees or invitees;
(d) any failure of Tenant to comply with any requirement of any governmental
authority; (e) any prosecution or defense of any suit or other proceeding in
discharging the Project, the Building or the Premises or any part thereof from
any liens, judgments or encumbrances created or suffered by Tenant upon or
against the same or against Tenant's leasehold estate; (f) any proceedings in
obtaining possession of the Premises from Tenant or its assigns after the
termination of this Lease by forfeiture or otherwise; (g) any litigation
commenced by or against Tenant to which Landlord is made a party; and (h) any
failure on the part of Tenant to perform or comply with any covenant or
agreement required to be performed or complied with by Tenant hereunder. The
provisions of this Section 12.01 shall survive the expiration or termination of
this Lease.

12.02. RELEASE OF LANDLORD. Except for Landlord's negligence or willful
misconduct, property of any kind that may be on or at the Premises shall be at
the sole and absolute risk of Tenant or those claiming through or under Tenant.

                                       24






(g) theft or burglary resulting in any loss to Tenant or its employees; or (h)
any nuisance made or suffered.

12.03. TENANT'S INSURANCE.

         (a) Throughout the Term, Tenant shall provide and maintain an "all
risk" form property insurance policy on all of Tenant's fixtures, equipment,
machinery, improvements, furniture and personal property, in the amount of the
full replacement cost thereof, including coverage against, without limitation,
sprinkler and water damage. A copy of such policy will be provided to Landlord
on request.

         (b) Throughout the Term, Tenant shall provide and maintain a policy of
commercial general liability insurance with respect to the Premises, written on
an "occurrence" basis, with a combined single limit per occurrence of at least
$1,000,000.00, and a general aggregate limit of at least $2,000,000.00, and
including without limitation, personal injury and contractual liability coverage
for the performance by Tenant of the indemnity agreements set forth in this
Lease. Tenant's liability insurance policy shall name Landlord, any Mortgagee,
Landlord's management company, and any designee of Landlord as additional
insureds. The policy shall be written by an insurance company licensed to do
business in the state where the Building is located and reasonably satisfactory
to Landlord. A copy of such policy will be provided to Landlord on request.

         (c) All insurance policies required to be carried under this Lease by
or on behalf of Tenant shall provide, and Tenant shall provide Landlord with
certificates stating that: unless Landlord and each other additional insured

insurance shall not be canceled and shall continue in full force and effect,
(ii) the insurance carrier shall not fail to renew the insurance policies for
any reason, and (iii) no material change may be made in an insurance policy. As
used in this Lease, the term "insurance policy" shall include any extensions or
renewals of an insurance policy.

and maintain an "all risk" form property insurance policy covering the Building
and any leasehold improvements in the Premises installed as part of Landlord's
Work, and such other insurance as Landlord reasonably determines from time to
time. The insurance coverage's and amounts in this Section 12.04 will be
determined by Landlord in its sole discretion.

                                  ARTICLE XIII.
                           COVENANT OF QUIET ENJOYMENT

13.01. Landlord covenants that if Tenant shall pay the Base Rent and Additional
Rent and perform all of the terms and conditions of this Lease to be performed
by Tenant, Tenant shall during the Term peaceably and quietly occupy and enjoy

Lease, any Mortgage to which this Lease is subordinate and any encumbrances of
record affecting the Premises.


                                       25



                                  ARTICLE XIV.
                               DEFAULTS; REMEDIES

14.01. DEFAULTS.  Each of the following events shall constitute a Default:

       (a) Tenant or any Guarantor (i) makes an assignment for the benefit of
creditors, (ii) files a petition in any court (whether or not pursuant to any
statute of the United States or of any state) in any bankruptcy, reorganization,
composition, extension, arrangement or insolvency proceedings, (iii) fails to
cause any such petition filed against Tenant or any Guarantor to be dismissed
within ninety (90) days, (iv) applies for the appointment of a trustee or
receiver for it or all or any portion of its property, or (v) fails to cause any
such receivership or trusteeship to be set aside within ninety (90) days after
such appointment.

       (b) Tenant fails to pay any installment of Base Rent or Additional Rent
or any other charge required to paid by Tenant under this Lease within ten (10)
days after the due date thereof.

       (c) Tenant fails to perform or observe any of its other obligations
under this Lease and such failure continues for a period of thirty (30) days
after written notice thereof from Landlord to Tenant; provided, however, that if
such failure cannot reasonably be cured within such 30-day period, a Default
shall not exist hereunder if Tenant commences an appropriate cure promptly
within such 30-day period and thereafter pursues such cure diligently to
completion within a period not to exceed sixty (60) days.

       (d) Tenant abandons or vacates the Premises, or fails to take occupancy
of the Premises within ten (10) days after the Commencement Date, unless Tenant
commences to and continues to promptly pay the rent for the Premises, allows
Landlord continuous access to the Premises during Tenant's absence and Tenant
pays Landlord any additional operating and other costs occasioned by Tenant's
absence.

14.02. REMEDIES.

       (a) Upon the occurrence of a Default, Landlord may, in addition to
pursuing any other remedy available to Landlord under this Lease, at law or in
equity, either (i) cancel and terminate this Lease, and this Lease shall not be
treated as an asset of Tenant's bankruptcy estate, and such termination will not
release Tenant from liability for all amounts as provided in subsection (c)
hereof; or (ii) terminate Tenant's right to possession only without canceling,
terminating or releasing Tenant's continued liability as set forth in subsection
(b) hereof. Notwithstanding the fact that initially Landlord elects to terminate
Tenant's right to possession only, Landlord shall have the continuing right to
cancel and terminate this Lease at any time thereafter by giving written notice
to Tenant.

       (b) In the event Landlord elects to terminate Tenant's right to
possession only, Landlord may, at Landlord's option, enter into the Premises and
take and hold possession thereof, without such entry into possession terminating
this Lease, constituting an acceptance of surrender or releasing Tenant in whole
or in part from Tenant's obligation to pay all amounts hereunder for the full
stated Term. Upon such reentry, Landlord may remove all persons and property
from the Premises and such property may be removed and stored in a public
warehouse or elsewhere at the






                                       26





cost of and for the account of Tenant, without Landlord becoming liable for any
loss or damage which may be occasioned thereby. Such reentry may be conducted in
any lawful manner. Upon and after entry into possession without termination of
the Lease, Landlord may, but will not be required to, relet the Premises, or any
part thereof, to anyone other than Tenant, for such time and upon such terms as
Landlord shall determine. Whether or not Landlord re-enters the Premises, upon
the election by Landlord to terminate Tenant's right to possession, Tenant shall
be liable to Landlord for (i) all attorneys' fees and other enforcement costs
incurred by Landlord by reason of the Default or in connection with exercising
any remedy hereunder; (ii) the unpaid installments of Base Rent or Additional
Rent or other unpaid sums which were due prior to such termination of right to
possession, including interest and late payment fees, which sums shall be
payable immediately; (iii) the installments of Base Rent and Additional Rent and
other sums falling due pursuant to the provisions of this Lease for the periods
after termination of Tenant's right to possession during which the Premises
remain vacant, including interest, which sums shall be payable as they become
due hereunder; (iv) all reasonable, actual, out-of-pocket expenses incurred in
reletting or attempting to relet the Premises including, without limitation,
costs for leasing commissions, remodeling and fixturing, substantially the same
configuration as exists at the time of reentry and without addition of material
improvements which shall be payable by Tenant as they are incurred by Landlord;
and (v) while the Premises are subject to any new lease or leases made pursuant
to this subsection (b), for the amount by which the monthly installments payable
under such new lease or leases is less than the monthly installments for all
Rent and other charges payable pursuant to this Lease, which deficiencies shall
be payable monthly.

       (c) Notwithstanding Landlord's initial election to terminate Tenant's
right to possession only, and notwithstanding any reletting without termination,
Landlord, at any time thereafter, may elect to terminate this Lease, and to
recover from Tenant (and Tenant agrees to pay on demand), in lieu of the amounts
which would thereafter be payable pursuant to the foregoing subsection (b), but
not in lieu of any amounts accruing prior to such election to terminate this
Lease, as damages for loss of the bargain and not as a penalty, (i) an amount
equal to the total of the Base Rent and Additional Rent which would otherwise
have been payable hereunder during the entire remaining Term, reduced by the
then fair market rental value of the Premises for the same period, and
discounted to present value using an interest factor of five percent (5%) per
annum over the applicable period of time and (ii) all expenses incurred by
Landlord as a result of the Default including, without limitation, leasing
commissions, attorneys' fees and other enforcement costs.

       (d) In addition to the foregoing remedies, Landlord may (but shall not be
obligated to) make any payment or do any act required in Landlord's judgment to
cure the Default, and charge the cost thereof to Tenant. Such amount shall be
due and payable upon demand; however, the making of such payment or the taking
of such action by Landlord shall not be deemed to cure the Default or to stop
Landlord from pursuing any remedy to which Landlord would otherwise be entitled.

14.03. LANDLORD'S LIEN AND SECURITY INTEREST.

       (a) As security for payment of Base Rent, Additional Rent, damages and
all other payments required to be made under this Lease by Tenant, Tenant grants
to Landlord a lien upon and security interest in all furniture and furniture
systems, (collectively, "Tenant's Property"). If 







                                       27






Tenant abandons or vacates any substantial portion of the Premises or a Default
exists, Landlord may enter upon the Premises, using force if permitted under
applicable law, and take possession of all or any part of Tenant's Property, and
may sell all or any part of Tenant's Property at a public or private sale, in
one or successive sales, with or without notice to the highest bidder for cash,
and, on behalf of Tenant, sell and convey all or part of Tenant's Property to
the highest bidder, and deliver to the highest bidder all of Tenant's title and
interest in the property sold. The proceeds of the sale of Tenant's Property
shall be applied by Landlord toward the reasonable costs and expenses of the
sale, including attorney's fees, and then toward the payment of all sums then
due by Tenant to Landlord under the terms of this Lease. Any excess remaining
shall be paid to Tenant or any other person entitled to the same by law. Not
withstanding the foregoing, any statutory lien or other lien granted by law in
favor of Landlord, in order to secure the payment of any amounts due hereunder,
is not waived, the express liens granted in this Lease being in addition to any
such statutory lien.

       (b) This Lease is intended as and constitutes a security agreement within
the meaning of the Uniform Commercial Code of the state in which the Premises
are situated. Landlord, in addition to, but not in limitation of, the rights
prescribed in this Lease, shall have all the rights, titles, liens and interests
in and to Tenant's Property, now or hereafter located upon the Premises, which
may be granted to a secured party, as that term is defined under the Uniform
Commercial Code, in order to secure to Landlord payment of all sums due and the
full performance of all of Tenant's obligations under this Lease. Tenant will,
upon request, execute and deliver to Landlord one or more financing statements
for the purpose of perfecting Landlord's security interest under this Lease, or
Landlord may file this Lease or a copy thereof as a financing statement. Unless
otherwise provided by law and for the purpose of exercising any right pursuant
to this Section, Landlord and Tenant agree that reasonable notice shall be given
if such notice is mailed to Tenant at least ten (10) days prior to any sale.

14.04. LANDLORD'S DEFAULT. If Landlord fails to perform or observe any material
covenant, term, provision or condition of this Lease and such default should
continue beyond a period of thirty (30) days after written notice by Tenant (or
such longer period as is reasonably necessary to remedy such default, provided
Landlord shall continuously and diligently pursue such remedy at all times until
such default is cured) then, in any such event Tenant shall have the right to
commence such actions at law or in equity to which Tenant may be entitled.
Tenant shall not be entitled to offset against Base Rental and Additional Rental
next coming due, or to counterclaim for any amounts owed to Tenant by Landlord
pursuant to this Lease. The rights of Tenant pursuant to this Section 14.04
shall be subject to (and, if applicable Tenant shall have the benefit of) the
express provisions of this Lease, if any, providing for remedies different from,
and in exclusion of, the remedies above-described. Tenant agrees that the cure
of any default by any of the Notice Parties shall be deemed a cure by Landlord
under this Lease.

14.05. ADDITIONAL REMEDIES, WAIVERS, ETC. The rights and remedies of Landlord
and Tenant set forth herein shall be in addition to any other right and remedy
now and hereafter provided by law. All rights and remedies shall be cumulative
and not exclusive of each other. No waiver of a Default shall extend to or
affect any other Default or impair any right or remedy with respect thereto. No
action or inaction by either party shall constitute a waiver of a Default. The
acceptance by Landlord of any Base Rent, Additional Rent or other amounts,
whether partial or full payment, shall not constitute an accord and satisfaction
or a waiver of any Default. The


                                       28







acceptance of any Base Rent or Additional Rent from any third party shall not
constitute a waiver of any of the restrictions of Article IX. No waiver of a
Default shall be effective against either party unless the same is in writing
and is duly executed by an authorized representative of such party.

Landlord. Each certificate shall contain the following information certified by
the person executing it on behalf of Tenant: (i) whether Tenant is in possession
of the Premises; (ii) whether this Lease is modified and in full force and
effect (or if there has been a modification of this Lease, whether this Lease is

At any time during the Term, Landlord may, at its option, substitute for the

shall give written notice to Tenant of such substitution not less than sixty
(60) days prior to the effective date thereof; (ii) the New Premises shall be
similar to the Premises in configuration, and the New Premises shall not
contain more than 105% or less than 95% of the number of rentable square feet of
space than the number of rentable square feet of space contained in the

Security Deposit shall be increased or decreased, if necessary, to reflect the
difference, if any, in the number of rentable square feet of space contained in

and expense, shall make such improvements to the, New Premises as may be
necessary to render the New Premises comparable to the Premises, and Landlord

RE: OFFICE LEASE AGREEMENT

Dear Rory:

We are pleased to return your fully executed copy of OpTel's office lease     
agreement at 1111 West Mockingbird. Thanks for your business. It was indeed     
a pleasure to negotiate with you. Your team did a thorough job finalizing the   
lease, but I regretted that you weren't involved all the way through.           
                                                                                
I want to invite you, Ada, Jean-Francois and Bob to dinner on Friday, August 4 
to celebrate OpTel's relocation to 1111 West Mockingbird.

                                                                          

Sincerely,
