                                       3

 
in paragraph 1(g) shall not be affected. Regardless of whether or not the Work

Premises on the 18th floor of the Building which is not Substantially Complete.
If Tenant has delayed completion of plans for the Work or has delayed Landlord's
efforts to Substantially Complete the Work or is in default hereunder or is

there shall not be any abatement of Base Rent, Rent or other Tenant obligations
with respect to such portion of the Premises.

4.  USE.
    --- 

     Subject to the restrictions set forth in this paragraph 4, the Premises
shall be used and occupied for general office use associated with computer
services and for no other purposes.  The Tenant will not make or permit to be
made any use of the Premises or any part thereof which would violate any of the
covenants, agreements, terms, provisions and conditions of this Lease, the
Ground Lease, or the Master Ground Lease or which directly or indirectly is
forbidden by public law, ordinance or governmental regulation or which may be
dangerous to life, limb, or property, or which may invalidate or increase the
premium cost of the policy of insurance carried on the Building or covering its
operation, and Tenant will not suffer or permit the Premises or any part thereof
to be used in any manner or allow anything to be brought into or kept therein
which, in the judgment of Landlord, shall in any way impair or tend to impair
the character, reputation or appearance of One Warren Place as a high quality
office building, or which will impair or interfere with or tend to impair or
interfere with any of the services performed by Landlord for One Warren Place or
any services performed for the Warren Place Common Areas.  Further, Tenant will
not make or permit to be made any use of the Premises or any part thereof as a
Bank (herein defined), a medical office, a hospital or a clinic.  For the
purpose of this paragraph the term "Bank" shall mean (i) the principal office of
a national banking association chartered under federal law ("National Bank"),
the principal office of a state banking corporation chartered under the Oklahoma
Banking Code of 1965 [6 O.S. (1991), 101, et seq.] ("State Bank"), the principal
office of a savings and loan association ("Savings and Loan Association"), or

                                       4

 
office of a credit union ("Credit Union"), (ii) branch offices of a National
Bank, State Bank, Savings and Loan Association or Credit Union which are
providing savings and/or checking facilities, or (iii) a walk-up or drive-in
teller or automatic teller facility of a National Bank, a State Bank, a Savings
and Loan Association or a Credit Union.

5.  BASE RENT.
    --------- 

     (a) At all times during the Lease Term Tenant shall pay to Landlord,
without any prior demand or notice and without any deduction, offset or
counterclaim whatsoever, the Base Rent and all other sums of money constituting
Rent hereunder, and Tenant specifically agrees that its nonpayment of any Rent
due hereunder shall entitle the Landlord to exercise all rights and remedies as
are herein provided.  The annual Base Rent for each calendar year or portion
thereof during the Lease Term, together with any estimated adjustment thereto
pursuant to paragraph 6 hereof then in effect, shall be due and payable in
advance, in twelve (12) equal installments on the first day of each calendar
month during the Lease Term, and Tenant hereby agrees to pay such Base Rent and
any adjustments thereto to Landlord at Landlord's address set forth herein (or
such other address as may be designated by Landlord in writing from time to
time) monthly, in advance, and without demand.  If the Lease Term commences on a
day other than the first day of the month or terminates on a day other than the
last day of a month, then the installments of Base Rent and any adjustments
thereto for such month or months shall be prorated, based on the number of days
in such month.

     (b) In addition to the foregoing Base Rent, Tenant agrees to pay Landlord
all charges for any service, goods, or materials furnished by Landlord under
this Lease within ten (10) days after Landlord renders a statement therefor to
Tenant.  Should any monthly installment of Base Rent or other payment due
hereunder not be paid on or before ten (10) days after said installment or other
payment is due and payable hereunder, then, and in that event, Tenant agrees to
pay a late payment charge equal to the amount determined by multiplying twenty
percent (20%) per annum by the amount of the unpaid installment or other payment
due hereunder, as the case may be, by a fraction the numerator of which is the
number of days which elapse after the due date through the date of payment in
full of such installment or other payment, as the case may be, together with the
late payment charge, and the denominator of which is 365; provided, however,
nothing herein contained shall ever entitle Landlord, upon the arising of any
contingency whatsoever, to receive or collect any late payment charge hereunder
or pursuant to any other provision of this Lease including, but not limited to,
paragraph 27 hereof determined, at a rate in excess of the highest lawful rate
allowed by the laws of the State of Oklahoma on any money obligation hereunder
and in no event shall Tenant be obligated to pay any late payment charge thereon
determined at a rate in excess of such lawful rate.

6.  BASE RENT ADJUSTMENTS.
    --------------------- 

     The Base Rent payable hereunder shall be adjusted upward 

                                       5

 
from time to time in accordance with the following provisions:

     (a) Tenant's Base Rent is based, in part, upon annual Basic Costs not
exceeding the actual Basic Costs for calendar year 1993.  Tenant shall pay as an
adjustment to Base Rent hereunder an amount (per each square foot of Rentable
Area within the Premises) equal to the excess ("Excess") from time to time of
(i) actual Basic Costs per square foot of Rentable Area in the Building over
(ii) the Basic Costs for calendar year 1993 divided by the number of square feet
of Rentable Area in the Building; provided, however, for purposes of this Lease,
Landlord's calculation of Basic Costs for each year after 1993 will be limited
as follows:  (A) Landlord will limit increases in each category of expenses,
except the tax and insurance categories, to ten percent (10%) of the prior
years' total cost; and (B) there shall not be any limit on increases in the tax
and insurance expense categories.  Landlord may collect such additional Base
Rent in arrears on a yearly basis.  Landlord shall also have the option to make
a good faith estimate of the Excess for each upcoming calendar year and upon
thirty (30) days' written notice to Tenant may require the monthly payment of
Base Rent adjusted in accordance with such estimate.  Any amounts paid based on
such an estimate shall be subject to adjustment pursuant to paragraph 6(b) when
actual Basic Costs are available for each calendar year.

     (b) By April 1 of each calendar year during the Lease Term and by April 1
of the year following the calendar year in which the Lease Term terminates, or
as soon thereafter as practical, Landlord shall furnish to Tenant a statement of
Landlord's actual Basic Costs for the previous calendar year.  If for any
calendar year additional Base Rent collected for the prior year, as a result of
Landlord's estimate of Basic Costs, is in excess of the additional Base Rent
actually due during such prior year, then Landlord shall refund to Tenant any
overpayment (or at Landlord's option, apply such amount against Rent due or to
become due hereunder).  Likewise, Tenant shall pay to Landlord, on demand, any
underpayment with respect to the prior year.

     (c) Tenant at its own expense shall have the right no more frequently than
once per calendar year, following prior written notice to Landlord, to examine
Landlord's books and records relating to Basic Costs, during normal business
hours only, and at a time agreed upon by the Landlord and Tenant; or at
Landlord's sole discretion, Landlord will provide an audit prepared by an
independent certified public accountant.

     (d) Notwithstanding any language herein seemingly to the contrary, if the
Building is not fully occupied during any calendar year of the Lease Term, Basic
Costs and the Excess for purposes of paragraphs 6(a) and 6(b) hereof shall be
determined as if the Building had been fully occupied during such year.  For the
purposes of this Lease, "fully occupied" shall mean occupancy of ninety-five
percent (95%) of the Rentable Area in the Building.

7.  SERVICES TO BE FURNISHED BY LANDLORD.
    ------------------------------------ 

                                       6

 
     Landlord agrees to furnish Tenant the following services, if Tenant is not
in default:

     (a) Domestic water at those points of supply provided for general use of
other tenants in the Building, central heat and air conditioning in season, at
such temperatures and in such amounts as are considered by Landlord to be
standard or as required by governmental authority; provided however, heating and
air conditioning service at times other than for Normal Business Hours for the
Building, shall be furnished only upon the written request of Tenant delivered
to Landlord prior to 3:00 p.m. of the prior business day such usage is
requested.  (For purposes of any such request, the term "business day" shall
mean Monday through Friday other than State or Federal holidays.  A request for
heating or air-conditioning service on a Sunday or at times other than Normal
Business Hours on a Saturday must be delivered not later than 3:00 p.m. on the
preceding business day, as defined above.)  Tenant shall bear the entire cost of
such additional service as such costs are determined by Landlord from time to
time.

     (b) Routine maintenance and electric lighting service for all Common Areas
and Service Areas of the Building in the manner and to the extent deemed by
Landlord to be standard.

     (c) Janitorial service as contracted by Landlord, Mondays through Fridays,
exclusive of normal business holidays; provided, however, if Tenant's floor
covering or other improvements require special treatment, Tenant shall pay the
additional cleaning cost attributable thereto as Rent upon presentation of a
statement therefor by Landlord.

     (d) Subject to the provisions of paragraph 13, facilities to provide all
electrical current required by Tenant in its use and occupancy of the Premises.

     (e) All Building Grade fluorescent bulb replacement in the Premises

Improvements and fluorescent and incandescent bulb replacement in the Common
Areas and Service Areas.

     (f) Security in the form of limited access to the Building during other
than Normal Business Hours shall be provided in such form as Landlord deems
appropriate.  Landlord may require those tenants requesting access to the
Building during other than Normal Business Hours to pay a fee for such access
partially to reimburse Landlord for the cost of the system which limits after-
hours access.  Landlord, however, shall have no liability to Tenant, its
employees, agents, invitees or licensees for losses due to theft or burglary, or
for damages done by unauthorized persons on the Premises and neither shall
Landlord be required to insure against any such losses.  Tenant shall cooperate
fully in Landlord's efforts to maintain security in the Building and shall
follow all regulations promulgated by Landlord with respect thereto.

     The failure by Landlord to any extent to furnish, or the

                                       7

 
interruption or termination of these defined services in whole or in part,
shall not render Landlord liable in any respect nor be construed as an eviction
of Tenant, nor work an abatement of Rent, nor relieve Tenant from the obligation
to fulfill any covenant or agreement hereof. Should any of the equipment or
machinery used in the provision of such services for any cause cease to function
properly, Tenant shall have no claim for offset or abatement of Rent or damages
on account of an interruption in service occasioned thereby or resulting
therefrom.

8.  IMPROVEMENTS TO BE MADE BY LANDLORD; PAYMENTS REQUIRED OF TENANT.
    ---------------------------------------------------------------- 

     Simultaneously with execution of this Lease, Landlord and Tenant will sign
a Work Letter in the form of Exhibit "D" attached to this Lease.  Except as
otherwise provided in the Work letter, all installations and improvements now or
hereafter placed on the Premises other than or in excess of Building Standard
Improvements shall be for Tenant's account and at Tenant's cost (and Tenant
shall pay ad valorem taxes and increases in insurance thereon or attributable
thereto), which cost shall be payable by Tenant to Landlord upon demand as Rent.
Tenant shall pay all sums which it is required to pay under the Work Letter.

required to make any repairs to the Premises or the Building.

10.  GRAPHICS.
     -------- 

     Landlord shall provide and install, at Tenant's cost, all letters or
numerals on doors in the Premises; all such letters and numerals shall be in the
standard graphics for the Building and no others shall be used or permitted on
the Premises or elsewhere on One Warren Place, without Landlord's prior written
consent.  Landlord will install, at Tenant's cost, on the sign monument, located
directly north of One Warren Place a single sign provided by Tenant which
conforms in all respects to current signage on the sign monument, including
size, shape, color and quality and which sign is in all respects acceptable to

Warren Place without Landlord's prior written consent.

11.  CARE OF THE PREMISES BY TENANT.

     Tenant agrees not to commit or allow any waste to be committed on any

tear excepted.

12.  REPAIRS AND ALTERATIONS BY TENANT.
     --------------------------------- 

                                       8

 
     Tenant covenants and agrees with Landlord, at Tenant's own cost and expense
to repair or replace any damage done to Warren Place, One Warren Place, the
Building, the Premises, or any part of any of such property, caused by Tenant or
Tenant's agents, employees, invitees, or visitors, and such repairs shall
restore the damaged property to as good a condition as it was in prior to such
damage, and shall be effected in compliance with all applicable laws; provided;
however, if Tenant fails to make such repairs or replacements promptly, Landlord
may, at its option, make repairs or replacements, and Tenant shall pay the cost
thereof to Landlord on demand as Rent.  Tenant agrees with Landlord not to make
or allow to be made any alterations to the Premises, install any vending
machines on the Premises, or place signs anywhere in One Warren Place or the
Warren Place Common Areas, without first obtaining written consent of Landlord
in each such instance, which consent may be given on such conditions as Landlord
may elect.  The Tenant shall not contract for any work or service which might
involve the employment of labor incompatible with the Building employees or
employees or contractors doing work or performing services by or on behalf of
the Landlord.  Any and all alterations to the Premises shall become the property
of Landlord upon termination of this Lease (except for movable equipment or
furniture owned by Tenant).  Landlord may, nonetheless, require Tenant to remove
any and all fixtures, equipment and other improvements installed on the Premises
and thereafter to restore Premises.  In the event that Landlord so elects, and
Tenant fails to remove such Improvements, Landlord may remove such improvements
at Tenant's cost, and Tenant shall pay Landlord on demand the cost of restoring
the Building Standard Improvements to the Premises.

13.  USE OF ELECTRICAL SERVICES BY TENANT.
     ------------------------------------ 

     Tenant's use of electrical services furnished by Landlord shall be subject
to the following:

     (a) Tenant's electrical equipment shall be restricted to that equipment

lighting shall not have a design load greater than an average of two (2) watts

an electrical design load greater than an average of two and one-half (2-1/2)
watts per square foot.

     (b) If Tenant's consumption of electrical services exceeds either the rated
capacities and/or design loads as per paragraph 13(a), then Tenant shall remove
such equipment and/or lighting to achieve compliance within ten (10) days after
receiving notice from Landlord.  Alternatively, upon receiving Landlord's prior
written approval, such equipment and/or lighting may remain in the Premises,
subject to the following:

     (i) Tenant shall pay for all costs of installation and maintenance of
submeters, wiring, air conditioning and other items required by Landlord, in
Landlord's discretion, to accommodate Tenant's excess design loads and
capacities.

                                       9

demand and consumption of electrical service at rates determined by Landlord,
which shall be in accordance with any applicable laws.

however, (i) Landlord shall have the right, from time to time, to relocate the
reserved parking spaces to another location in the One Warren Place parking
garage, but not on the top level of the One Warren Place parking garage, (ii)
Landlord shall have no obligation or responsibility to Tenant for enforcing the
reservation of these reserved parking spaces or for patrolling the area in which
the reserved parking spaces are located, (iii) Landlord shall have no liability
or responsibility to Tenant for the unauthorized use of such reserved parking
spaces, and (iv) such authorized use of the reserved parking spaces shall not
result in any diminution of Tenant's obligations hereunder and shall not in any

shall pay as rent for the one hundred forty-one (141) nonexclusive and
unreserved parking spaces at the rate of $7.50 per space per month (plus sales

reserves the right to assign or reserve such parking spaces as it may elect, in
its sole subjective discretion.  Tenant shall not sublease any of its parking
spaces or assign any rights thereto.  No vehicle in excess of seventy-two (72)
inches in height shall

                                       10

 
be allowed access to the One Warren Place parking garage, and vehicles which are
unmoved or abandoned for more than three (3) days will be removed from the One

held by Tenant, which list shall be in form, scope and substance satisfactory to
Landlord, in its sole subjective discretion, and shall identify the individual
to whom an access card has been issued, the vehicle used by such individual and
the license plate number of such vehicle.

     (d) Tenant shall immediately report to Landlord any lost access card, and
Tenant shall pay Landlord's then current charge for a replacement access card,
which charge shall not be less than $30.00 per access card at any time.

     (e) In the event of unauthorized or improper use of an access card, as
determined by Landlord in its sole judgment, Landlord may, in its sole
subjective discretion, (i) withdraw the access card and terminate Tenant's right
to use the parking space represented by the access card, all without terminating
or otherwise affecting Tenant's responsibilities, obligations and liabilities
under the covenants, agreements, terms, conditions and provisions contained in
this Lease and (ii) exercise any of Landlord's other rights and remedies against
Tenant.

     (f) Each access card shall at all times remain the property of Landlord,
and Tenant shall surrender all access cards to Landlord immediately upon
termination of this Lease.  Notwithstanding termination of this Lease, Tenant
shall pay to Landlord for each lost access card Landlord's then current charge
for a replacement access card, which charge shall not be less than $30.00 per
card at any time.

15.  LAWS AND REGULATIONS.
     -------------------- 

     Tenant agrees to comply with all applicable laws, ordinances, rules and
regulations of any governmental entity or agency having jurisdiction of the
Premises.

16.  BUILDING RULES.
     -------------- 

                                       11

 
     Tenant will comply with the rules and regulations of One Warren Place
adopted and altered by Landlord from time to time and with the rules adopted and
altered from time to time for the Warren Place Common Areas, and Tenant will
cause all of its agents, employees, invitees and visitors to comply with all
such rules.  All changes to such rules will be sent by Landlord to Tenant in
writing.  The current rules and regulations are listed in Exhibit "E" attached
to this Lease.

17.  ENTRY BY LANDLORD.
     ----------------- 

     (a) On reasonable prior notice to the Tenant, Landlord may enter the
Premises to exhibit the Premises to prospective Tenants during the last twelve
(12) months of the Lease Term, and to any prospective purchaser, mortgagee, or
assignee of any mortgage on One Warren Place or any interest therein and to
others having a legitimate interest at any time during the Lease Term.

     (b) Landlord may enter the Premises at any time in the event of an
emergency, and otherwise at reasonable times during Normal Business Hours, to
take any and all measures, including inspections, repairs, alterations,
additions and improvements to the Premises or to One Warren Place, as may be
necessary or desirable for the safety, protection or preservation of the
Premises or any other part of One Warren Place or the Landlord's interest
therein, or as may be necessary or desirable in the operation or improvement of
One Warren Place, or any part thereof, or in order to comply with all laws,
orders and requirements of governmental or other authority.

18.  ASSIGNMENT AND SUBLETTING.
     ------------------------- 

     (a) Tenant shall not assign, sublease, transfer or encumber this Lease or
any interest therein.  Any attempted assignment, sublease, transfer or
encumbrance by Tenant in violation of the terms and covenants of this paragraph
shall be void.

     (b) If Tenant requests Landlord's consent to an assignment of this Lease or
subletting of all or part of the Premises, Landlord shall have the option
(without limiting Landlord's other rights hereunder) of terminating this Lease
upon thirty (30) days notice and of dealing directly with the proposed assignee.
If Landlord should fail to notify Tenant in writing of its decision within a
thirty (30) day period after Landlord is notified in writing of the proposed
assignment or sublease, Landlord shall be deemed to have refused to consent to
any assignment or subleasing, and to have elected to keep this Lease in full
force and effect.

     (c) Tenant shall not, without consent of the Landlord, sublet this Lease to
the parent or subsidiary of a corporate lessee or assign this Lease in
connection with a consolidation, merger, or sale of controlling interest of the
Tenant.

     (d) All cash or other proceeds of any assignment, sale or sublease of
Tenant's interest in this Lease, whether consented to by Landlord or not, shall
be paid to Landlord notwithstanding the fact that such proceeds exceed the Rent
called for hereunder,

                                       12

 
unless Landlord agrees to the contrary in writing, and Tenant hereby assigns all
rights it might have or ever acquire in any such proceeds to Landlord. This
covenant and assignment shall benefit Landlord and its successors in ownership
of the Building and shall bind Tenant and Tenant's heirs, executors,
administrators, personal representatives, successors and assigns. Any assignee,
sublessee or purchaser of Tenant's interest in this Lease (all such assignees,
sublessees and purchasers being hereinafter referred to as "Successors"), by
assuming Tenant's obligations hereunder shall be deemed to have assumed
liability to Landlord for all amounts paid to persons other than Landlord by
such Successor in consideration of any such assignment, sale or subletting, in
violation of the provisions hereof.

19.  LIENS.
     ----- 

     Tenant will not permit any mechanics', materialmen's, laborers' or other
liens to be placed upon the Premises or any other part of One Warren Place or
Warren Place and nothing in this Lease shall be deemed or construed in any way
as constituting the consent or request of Landlord, express or implied, by
inference or otherwise, to any person for the performance of any labor or the
furnishing of any materials to the Premises, One Warren Place, Warren Place, or
any part thereof, nor as giving Tenant any right, power, or authority to
contract for or permit the rendering of any services or the furnishing of any
materials that would give rise to any mechanics', materialmen's, laborers' or
other liens against the Premises, One Warren Place or Warren Place.  In the
event any such lien is attached to the Premises, One Warren Place or Warren
Place, then, in addition to any other right or remedy of Landlord, Landlord may,
but shall not be obligated to, discharge the same.  Any amount paid by Landlord
for any of the aforesaid purposes shall be paid by Tenant to Landlord on demand
as Rent.

20.  PROPERTY INSURANCE.
     ------------------ 

     Landlord shall maintain fire and extended coverage insurance on the
building in such amounts as Landlord may from time to time require; provided,
however, so long as Metropolitan Life Insurance Company, or any other company
having assets of $500,000,000.00, is the owner of the Building, it shall have
the right to self-insure against any and all perils and/or liabilities against
which it would otherwise be required to insure and it shall also have the right
to effect any such insurance by means of so called "blanket" or "umbrella"
policies of insurance.  Any such insurance shall be maintained at the expense of
Landlord (the cost to Landlord being included as a part of the Basic Costs), and
payments for losses thereunder shall be made solely to Landlord and the
mortgagees of Landlord as their interest shall appear.  Tenant shall maintain at
its expense, in an amount equal to full replacement cost, fire and extended
coverage insurance on all of its personal property, including removable trade
fixtures, located in the Premises and in such additional amounts as are required
to meet Tenant's obligations pursuant to paragraph 24 hereof.  Tenant shall
provide Landlord with current certificates of insurance evidencing Tenant's
compliance with this paragraph 20 and

                                       13

 
paragraph 21. Tenant shall obtain the agreement of Tenant's insurers to notify
Landlord that a policy is due to expire at least thirty (30) days prior to such
expiration.

21.  LIABILITY INSURANCE.
     ------------------- 

     Tenant shall, at its expense, maintain a policy or policies of
comprehensive general liability insurance with respect to its activities in One
Warren Place and Warren Place, with the premiums thereon fully paid on or before
due date, issued by and binding upon an insurance company approved by Landlord,
such insurance to afford minimum protection of not less than $1,000,000.00
combined single limit coverage of bodily injury, property damage or combination
thereof.  Landlord shall not be required to maintain insurance against thefts
within the Premises, One Warren Place or Warren Place generally.  Subject to
Landlord's rights to self-insure or provide "blanket" or "umbrella" policies of
insurance as set forth in the first sentence of paragraph 20, Landlord shall
maintain liability insurance with respect to the Building in the form of one or
more policies, such insurance to afford minimum protection of not less than
$1,000,000.00 combined single limit coverage of bodily injury, property damage
or combination thereof.  The cost to Landlord of any such insurance shall be
included as a part of the Basic Costs.

22.  INDEMNITY.
     --------- 

     Landlord shall not be liable to Tenant, or to Tenant's agents, servants,
employees, customers, or invitees for any injury to person or damage to property
caused by any act, omission, or neglect of Tenant, its agents, servants, or
employees, invitees, licensees or any other person entering Warren Place or One
Warren Place under the invitation of Tenant or arising out of the use of One
Warren Place by Tenant and the conduct of its business or out of a default by
Tenant in the performance of its obligations hereunder.  Tenant hereby
indemnifies and holds Landlord harmless from all liability and claims for any
such damage or injury.

23.  WAIVER OF SUBROGATION RIGHTS.
     ---------------------------- 

     Except as otherwise provided in the next to the last sentence of paragraph
24, Landlord and Tenant each hereby waives on behalf of itself and its insurers
(none of which shall ever be assigned any such claim or be entitled thereto due
to subrogation or otherwise) any and all rights of recovery, claim, action, or
cause of action, against the other, its agents, officers, or employees, for any
loss or damage that may occur to the Premises, or any improvements thereto, or
the Building or any improvements thereto, or any personal property of such party
therein, by reason of fire, the elements, or any other cause or causes which are
insured against under the terms of the standard fire and extended coverage
insurance policies referred to in paragraph 20 hereof, regardless of whether
such insurance is actually maintained and regardless of the cause or origin,
including negligence of the other party hereto, its agents, officers, or
employees.

                                       14

 
24.  CASUALTY DAMAGE.
     --------------- 

     If the Premises or any part thereof shall be damaged by fire or other
casualty, Tenant shall give prompt written notice thereof to Landlord.  In case
the Building shall be damaged by fire or other casualty such that substantial
alteration or reconstruction of the Building shall, in Landlord's sole opinion,
be required (whether or not the Premises shall have been damaged by a casualty
affecting the Building) or in the event any mortgagee of Landlord's should
require that the insurance proceeds, or any portion thereof, payable as a result
of a casualty be applied to the payment of the mortgage debt or in the event of
any material uninsured loss to the Building or the Premises, Landlord may, at
its option, terminate this Lease by notifying Tenant in writing of such
termination within the later to occur of ninety (90) days after the date of such
casualty or ninety (90) days after the date of receipt of Tenant's notice
relating to the Premises.  If Landlord does not thus elect to terminate this
Lease, Landlord shall commence and proceed with reasonable diligence to restore
the Premises to substantially the same condition in which they were immediately
prior to the happening of the casualty (without regard, however, to alterations
made by or on behalf of Tenant, without Landlord's prior written consent),
except the Landlord's obligation to restore shall not exceed the scope of the
work required to be done by Landlord in originally constructing the Premises and
installing Building Standard Improvements in the Premises, nor shall Landlord be
required to spend for such work an amount in excess of the insurance proceeds
actually received by Landlord for the Building and the Building Standard
Improvements in the Premises as a result of the casualty.  When Building
Standard Improvements in the Premises have been restored by Landlord (to the
extent that insurance proceeds actually received by Landlord are sufficient to
complete such work), Tenant shall complete, at its sole cost and expense, the
restoration of the Premises, including, without limitation, the balance of the
Building Standard Improvements not completed by Landlord, the reconstruction of
all improvements in excess of Building Standard Improvements and the restoration
of Tenant's furniture and equipment.  Such work to be performed by Tenant shall
not result in any type of mechanic's or materialman's lien affecting the
Building, the Premises or any portion thereof and shall result in the
reconstruction or restoration of said items by Tenant to a condition that is at
least equal in quality to the condition of said items existing prior to such
damage or destruction.  Landlord shall have no liability to Tenant for the
Landlord's termination of the Lease in accordance with the provisions hereof, or
for any inconvenience or annoyance to Tenant or injury to the business or
property of Tenant resulting in any way from the occurrence of a casualty or the
repair of any damage or destruction related thereto, except that, subject to the
provisions of the next sentence, Landlord shall allow Tenant a fair diminution
of rent, as determined by Landlord, during the time and to the extent the
Premises are unfit for occupancy; provided, however, such unfitness for
occupancy shall not be construed to constitute an actual or constructive
eviction.  If the Premises or any portion of One Warren Place be damaged by fire
or other casualty resulting from the fault or negligence of

                                       15

 
Tenant or any of Tenant's agents, employees, licensees, or invitees, the Rent
hereunder shall not be diminished, and regardless of whether this Lease is
terminated, Tenant shall be liable to Landlord for the cost of the repair and
restoration of the Premises and all other parts of One Warren Place including
all tenant improvements in the Building resulting therefrom to the extent such
cost and expenses exceed the amount of insurance proceeds actually received by
Landlord therefor, and Landlord shall retain all other rights and remedies that
Landlord may have at law, in equity or pursuant to this Lease. Anything in this
Lease to the contrary notwithstanding, if more than fifteen percent (15%) of the
Premises are damaged by fire or other casualty or if all or any portion of the
Premises is damaged by fire or other casualty during the last year of the term
(excluding the period during any renewal term, unless such fire or casualty
occurs during a renewal term) of this Lease, then Landlord may, at its option,
terminate this Lease by notifying Tenant in writing of such termination within
the later to occur of ninety (90) days after the date of receipt by Landlord of
Tenant's notice or within ninety (90) days after the date of such casualty.

25.  CONDEMNATION.
     ------------ 

     If the whole or substantially the whole of the Building or the Premises
should be taken for any public or quasi-public use, by right of eminent domain
or otherwise or should be sold in lieu of condemnation, then this Lease shall
terminate as of the date when physical possession of the Building or the
Premises is taken by the condemning authority.  If less than the whole or
substantially the whole of the Building or the Premises is thus taken or sold,
Landlord (whether or not the Premises are affected thereby) may terminate this
Lease by giving written notice thereof to Tenant; in which event this Lease
shall terminate as of the date when physical possession of such portion of the
Building or Premises is taken by the condemning authority.  If the Lease is not
so terminated upon any such taking or sale, the Base Rent payable hereunder
shall be diminished by an equitable amount, as determined by Landlord, and
Landlord shall, to the extent Landlord deems feasible, restore the Building and
the Premises to substantially their former condition, but such work shall not
exceed the scope of the work done by Landlord in originally constructing the
Building and installing Building Standard Improvements in the Premises, nor
shall Landlord in any event be required to spend for such work an amount in
excess of the amount received by Landlord as compensation for such taking.
Subject to the proviso at the end of this sentence, all amounts awarded upon a
taking of any part of all of Warren Place or One Warren Place shall belong to
Landlord, and Tenant shall not be entitled to, and expressly waives all claims
to, any such compensation; provided that if Landlord terminates this Lease based
on any such taking, Tenant shall have the right to appear and separately file a
claim for a separate award in an amount limited to Tenant's reasonable expenses
of moving from the Premises.

26.  DAMAGES FROM CERTAIN CAUSES.
     --------------------------- 

                                       16

 
     Landlord shall not be liable to Tenant for any loss or damage to any
property or person occasioned by theft, fire, act of God, public enemy,
injunction, riot, vandalism, malicious mischief, earthquake, flood, strike,
insurrection, war, court order, requisition, or order of governmental body or
authority or by any other cause beyond the control of Landlord.  Further,
subject to paragraph 34 of this Lease, Landlord shall not be liable for any
damage or inconvenience which may arise through repair or alteration of any part
of the Warren Place, One Warren Place or the Premises.

27.  EVENTS OF DEFAULT/REMEDIES.
     -------------------------- 

     (a) The following events shall be deemed to be events of default by Tenant
under this Lease:  (i) Tenant shall fail to comply with any of the terms,
provisions or covenants of this Lease or any other agreement between Landlord
and Tenant (including, without limitation, the Work Letter), all of which terms,
provisions and covenants shall be deemed material; (ii) the leaseholder
hereunder demised shall be taken on execution or other process of law in any
action against Tenant; (iii) Tenant notifies Landlord, at any time prior to the
Commencement Date, that Tenant does not intend to take occupancy of the Premises
upon the commencement of the Lease Term or Tenant shall fail to promptly move
into and take possession of the Premises when the Premises are ready for
occupancy or shall cease to do business in or abandon any substantial portion of
the Premises; (iv) Tenant shall become insolvent or unable to pay its debts as
they come due, or Tenant notifies Landlord that it anticipates either condition;
(v) Tenant takes any action or notifies Landlord that Tenant intends to file a
petition under any section or chapter of the Bankruptcy Code, as amended from
time to time, or under any similar law of statute of the United States or any
State thereof; or a petition shall be filed against Tenant under any such
statute or Tenant or any creditor of Tenant notifies Landlord that it knows such
a petition will be filed or Tenant notifies Landlord that it expects such a
petition to be filed; (vi) a receiver or trustee shall be appointed for Tenant's
leasehold interest in the Premises or for all or a substantial part of the
assets of Tenant; or (vii) Tenant shall default under any of the terms,
provisions or covenants of the Sublease.

     (b) Upon the occurrence of any event or events of default by Tenant,
whether enumerated in this paragraph or not, Landlord shall have the option to
pursue any one or more of the following remedies without any notice or demand
for possession whatsoever (and without limiting the generality of the foregoing,
Tenant hereby specifically waives notice and demand for payment of rent or other
obligations due and waives any and all other notices or demand requirements
imposed by applicable law):  (i) terminate this Lease in which case Tenant shall
immediately surrender the Premises to Landlord; (ii) terminate Tenant's right to
occupy the Premises and reenter and take possession of the Premises (without
terminating this Lease); (iii) enter upon the Premises and do whatever Tenant is
obligated to do under the terms of this Lease; and Tenant agrees to reimburse
Landlord on demand for any expense which Landlord may incur in effecting
compliance with Tenant's obligations under this Lease, and Tenant further agrees
that 

                                       17

 
Landlord shall not be liable for any damages resulting to Tenant from such
action; and (iv) exercise all other remedies available to Landlord at law or in
equity, including, without limitation, injunctive relief of all varieties.

     In the event Landlord elects to reenter or take possession of the Premises
after Tenant's default, Tenant hereby waives notice of such reentry or
repossession and of Landlord's intent to reenter or retake possession.  Landlord
may, without prejudice to any other remedy which it may have for possession or
arrearages in Rent, expel or remove Tenant and any other person who may be
occupying said Premises or any part thereof.  In addition, the provisions of
paragraph 30 hereof shall apply with respect to the period from and after the
giving of notice of such termination to Tenant.  All Landlord's remedies shall
be cumulative and not exclusive.  Forbearance by Landlord to enforce one or more
of the remedies herein provided upon an event of default shall not be deemed or
construed to constitute a waiver of such default.

     (c) This paragraph 27 shall be enforceable to the maximum extent not
prohibited by applicable law, and the unenforceability of any portion thereof
shall not thereby render unenforceable any other portion.  Tenant and Landlord
hereby agree that no action or inaction by Landlord or its agents, servants or
employees, except written notice to Tenant as provided herein or judicial
proceedings, shall be sufficient to evidence or effect termination of this
Lease.

     (d) Landlord shall be in default hereunder in the event Landlord has not
begun and pursued with reasonable diligence the cure of any failure of Landlord
to meet its obligations hereunder within thirty (30) days of the receipt by
Landlord of written notice from Tenant of the alleged failure to perform.  In no
event shall Tenant have the right to terminate or rescind this Lease as a result
of Landlord's default as to any covenant or agreement contained in this Lease or
as a result of the breach of any promise or inducement hereof, whether in the
Lease or elsewhere.  Tenant hereby waives such remedies of termination and
rescission and hereby agrees that Tenant's remedies for default hereunder and
for breach of any promise or inducement shall be limited to a suit for damages
and/or injunction.  In addition, Tenant hereby covenants that, prior to the
exercise of any such remedies, it will give the mortgagees holding mortgages on
One Warren Place, or any interest therein, notice and a reasonable time to cure
any default by Landlord.

28.  PEACEFUL ENJOYMENT.
     ------------------ 

     Tenant shall, and may peacefully have, hold and enjoy the Premises, subject
to the other terms hereof and the terms of the Ground Lease and Master Ground
Lease, provided that Tenant pays the Rent to be paid by Tenant and performs all
of Tenant's covenants and agreements herein contained.  This covenant and any
and all other covenants of Landlord shall be binding upon Landlord and its
successors only with respect to breaches occurring during its or their
respective periods of ownership of the Tenant's interest hereunder. 
Landlord shall be entitled to 

                                       18

 
cause Tenant to relocate from the Premises to other space ("Relocation Space")
within Warren Place or the Building at any time after reasonable written notice
of Landlord's election (not in excess of ninety (90) days) is given to Tenant;
provided, however, so long as (a) no default has occurred under the terms of
this Lease, and (b) Tenant has not attempted to sublease any part of the
Premises or to assign this Lease, Landlord will not exercise its right to
relocate Tenant. Any relocation of Tenant pursuant to this paragraph shall be
entirely at the expense of Landlord or the third party replacing Tenant in the
Premises. Such a relocation shall not terminate or otherwise affect or modify
this Lease except that from and after the date of such relocation, "Premises"
shall refer to the Relocation Space into which Tenant has been moved, rather
than the original Premises as herein defined.

29.  CERTAIN RIGHTS RESERVED TO THE LANDLORD.
     --------------------------------------- 

     The Landlord reserves the following rights:

     (a) To name the Building and to change the name and street address of the
Building at any time, without responsibility to Tenant for any advertising,
billboards, printed materials or any other items of expense incurred by Tenant
in regard to a prior Building name or street address.

     (b) To install and maintain a sign on the exterior and interior of the
Building.

     (c) To designate all sources furnishing sign painting and lettering, ice,
drinking water, towels, toilet supplies, shoe shining, vending machines, mobile
vending service, catering, and like services used on the Premises or in One
Warren Place.

     (d) To constantly have pass keys to the Premises.

     (e) During the last ninety (90) days of the term, if during or prior to
that time the Tenant vacates the Premises, to decorate, remodel, repair, alter
or otherwise prepare the Premises for reoccupancy, without affecting Tenant's
obligation to pay Rent for the Premises.

30.  HOLDING OVER.
     ------------ 

     In the event Tenant or any of its successors in interest hold over the
Premises, or any part thereof, after the expiration or other termination of this
Lease or in the event Tenant continues to occupy the Premises after the
termination of Tenant's right of possession pursuant to paragraph 27(b)(ii)
hereof, unless otherwise agreed in writing, such holding over shall constitute
and be construed as a tenancy at will at a daily Base Rent equal to one-
thirtieth (1/30) of an amount equal to two (2) times the most recent Base Rent
payable under this Lease, as adjusted pursuant to paragraph 6(a) hereof.  All
other terms, covenants and conditions of this Lease shall continue to be in full
force and effect; provided no holding over by Tenant after the expiration of the
Lease Term shall be construed to extend the Lease Term.  The Tenant hereby
indemnifies and agrees to hold 

                                       19

 
Landlord harmless against any cost, expense, damages, or other liability,
including, without limitation, the cost of defending any claim or action by a
third party, resulting from Tenant's continued occupancy of the Premises after
the Lease Term.

31.  SUBORDINATION.
     ------------- 

     Tenant accepts this Lease and the Premises subject and subordinate to the
terms of the Ground Lease, the Master Ground Lease, and all future ground leases
(except as otherwise specifically provided in any such document), and Tenant
further accepts this Lease subject and subordinate to any first mortgage, deed
of trust or other lien presently existing or hereafter placed upon the Premises,
upon the Building, upon One Warren Place, or upon Warren Place, in whole or in
part, and to any renewals, refinancing and extensions thereof; provided,
however, any such subordination to a first mortgage, deed of trust or other lien
shall be evidenced by a Subordination, Non-Disturbance and Attornment Agreement
in the form of Exhibit "F" attached hereto, which Tenant specifically covenants
and agrees to execute and deliver from time to time as may be requested by
Landlord.  However, Tenant also agrees that any such first mortgagee shall have
the right at any time to subordinate such mortgage, deed of trust or other lien
to this Lease on such terms and subject to such conditions as such mortgagee may
deem appropriate in its discretion.  Landlord is hereby irrevocably vested with
full power and authority to subordinate this Lease to any mortgage, deed of
trust or other lien now existing or hereafter placed upon the Premises, the
Building, One Warren Place or Warren Place, in whole or in part, and Tenant
agrees upon demand to execute such further instruments subordinating this Lease
or attorning to the holder of any such liens as Landlord may request.  The terms
of this Lease are subject to approval by the Landlord's permanent lender(s), and
such approval is a condition precedent to Landlord's obligations hereunder.
Such lender(s) shall have discretion as to whether or not it shall enter an
attornment and nondisturbance agreement with Tenant and as to the form of any
such agreement.  In the event that Tenant should fail to execute any
subordination agreement or other agreement required by this paragraph, promptly
as requested, Tenant hereby irrevocably constitutes Landlord as its attorney-in-
fact to execute such instrument in Tenant's name, place and stead, it being
agreed that such power is one coupled with an interest.  Tenant agrees that it
will from time to time, within ten (10) days after request by Landlord, execute
and deliver to such persons as Landlord shall request a statement in recordable
form certifying that this Lease is unmodified and in full force and effect (or
if there have been modifications, that the same is in full force and effect as
so modified), stating the dates to which Rent and other charges payable under
the Lease have been paid, stating that Landlord is not in default hereunder (or
if Tenant alleges a default stating the nature of such alleged default) and
further stating such other matters as Landlord shall require.

32.  ATTORNEY'S FEES.
     --------------- 

     In the event either party defaults in the performance of any of the terms
of this Lease and the other party employs an 

                                       20

 
attorney in connection therewith, the defaulting party agrees to pay prevailing
party's reasonable attorney's fees, all court costs and other reasonable
expenses.

33.  NO IMPLIED WAIVER.
     ----------------- 

     The failure to insist at any time upon the strict performance of any
covenant or agreement herein, or to exercise any option, right, power or remedy
contained in this Lease shall not be construed as a waiver or a relinquishment
thereof for the future.  No payment by Tenant or receipt by Landlord of a lesser
amount than the monthly installment of Base Rent or other Rent due under this
Lease shall be deemed to be other than on account of the earliest such Rent due
hereunder, nor shall any endorsement or statement on any check or any letter
accompanying any check or payment as Rent be deemed an accord and satisfaction,
and Landlord may accept such check or payment without prejudice to Landlord's
right to recover the balance of such Rent or pursue any other remedy provided or
referenced in this Lease.

34.  PERSONAL LIABILITY.
     ------------------ 

     In no event shall Landlord be liable to Tenant, its employees, agents,
invitees or licensees, either for (a) any loss or damage that may be occasioned
by or through the acts or omissions of other tenants of the Building or of any
other persons whomsoever or (b) any consequential damages regardless of
causation.  With respect to tort claims against Landlord, Landlord shall not be
liable to Tenant, its employees, agents, invitees or licensees for any act or
omission of Landlord or of its agents or employees, except for actual damages or
costs incurred as a direct result or caused directly by the gross negligence or
willful misconduct of Landlord (or its agents or employees) in circumstances in
which Landlord is deemed to be liable at law, as evidenced by a final non-
appealable judgment in a court of law for such acts or omissions and only if
such liability cannot be waived by Tenant.  Nothing contained in the immediately
preceding sentence shall ever be construed as creating liability in excess of
that existing at law or, in any event, increasing the liability of Landlord,
under theory or cause of action, however denominated, from that existing at law.
Further, the liability of the Landlord to Tenant for (a) any default by Landlord
under the terms of this Lease or (b) any circumstance in which Landlord is
