                                    (Santa Clara)


    THIS LEASE (the "Lease") is made and entered into as of the 11th day of
March, 1997, by and between NATIONAL Semiconductor Corporation, a Delaware
corporation ("Landlord"), and FAIRCHILD Semiconductor Corporation, a Delaware
corporation ("Tenant").



                                      WITNESETH:


    WHEREAS, Landlord is the owner of two buildings known as Building 4 and
Building 9 (the "Buildings") located on a property having the address described
in Exhibit A (the "Property"); and

    WHEREAS, Landlord desires to lease that portion of the Buildings described
on Exhibit A (hereinafter, the "Premises").  

    NOW THEREFORE, in consideration of the mutual covenants and agreements
herein contained and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged by each of the parties, Landlord
and Tenant hereby stipulate and agree as follows:

    1.   PREMISES.  Landlord hereby leases to Tenant and Tenant hereby leases
from Landlord the Premises on the terms and conditions set forth in this Lease.

    2.   TERM.  The term of this Lease shall commence on the date hereof and
shall terminate on May 31, 1998 (the "Expiration Date"), unless sooner
terminated pursuant to the terms hereof, by which date Tenant agrees to vacate
the Premises.  The term of this Lease may be extended by the mutual agreement of
the parties.  Without limiting Landlord's right to refuse to enter into such a
mutual agreement, Landlord may require an increase in rental as a condition to
any such extension.  Tenant may, without penalty, terminate this Lease prior to
the Expiration Date, at any time, by written notice to Landlord specifying the
date for the termination of the Lease and delivered to Landlord at least thirty
(30) days prior to such date (the earlier of the Expiration Date and the date so
specified is hereinafter referred to as the "Termination Date").

    3.   USE.  Tenant shall use the Premises in a manner consistent with its
historical use.











    4.   RENT.  Tenant shall pay to Landlord base rent as adjusted pursuant to
Section 5 below (the "Base Rent") in accordance with the terms of the Base Rent
Schedule attached hereto and made a part hereof as Exhibit B.   The monthly Base
Rent shall be paid no later than the fifth day of each month for space provided
in that month.  If the term of this Lease begins or ends on any day other than
the first day of a calendar month, then the rental payments for such periods
shall be prorated on a per diem basis.

    5.   INCLUDED SERVICES.  Payment of Base Rent shall entitle Tenant, without
payment of additional charge, to use and receive, to the extent available at the
Property, such services as are both (i) normally provided for and included in
the per Accounting Period occupancy charge allocated to all other occupants of
the Property who are engaged in similar activities at the Property as the uses
thereof permitted Tenant hereby, and (ii) currently provided to the Tenant's
operations, (collectively, "Included Services").  Included Services shall
include, but are not limited to:  electricity, natural gas, water, sewer, and
garbage collection, heat, air conditioning, routine maintenance (e.g. cleaning
services), normal repair to maintain facilities in good condition, janitorial
services, security and badging services, parking in all parking areas and
garages, and cafeteria services.  Tenant's right to use and receive any Included
Services without charge shall be limited in volume and level to that which is
reasonable and which is consistent with Tenant's historical use.  Landlord shall
not be responsible for any decrease or interruption in the availability of any
Included Service caused by third parties or circumstances beyond Landlord's
control.  Should any such decrease occur, Landlord shall allocate the available
supply of such Included Service on an equitable basis.  In addition to the
Included Services, payment of Base Rent shall cover all state and local real
property taxes and assessments levied against the Property, but Tenant shall be
responsible for the payment of any taxes levied upon its personalty located at
the Property.

    6.   ADDITIONAL SERVICES.  Additional services as are both (i) normally
provided at a variable monthly allocated charge for all other occupants of the
Property who are engaged in similar activities at the Property as the uses
thereof permitted Tenant hereby, and (ii) currently provided to the Tenant's
operations, (collectively, "Additional Services"), shall be provided to Tenant
at the same rates as are charged to Landlord's departments and working groups
occupying the Property.  Additional Services include, but are not limited to: 
computer and network services, desktop computer maintenance and repair services,
voice and data communication services, shipping and receiving services
including, without limitation, mail delivery and package distribution, requested
maintenance and janitorial services beyond the scope included within Included
Services, and maintenance, janitorial and repair services necessitated by the
negligence of Tenant or its agents, employees or invitees.  Additional Services
shall be available to Tenant at a level and subject to terms and limitations
consistent with the availability of such services to the other occupants of the
Property.


                                          2






    7.   EXPANSION OR DECREASE OF LEASED SPACE.  

         (a)  Tenant may decrease the amount of space it occupies in the
Premises upon thirty (30) days prior written notice to Landlord;  however, such
space may not be increased without the consent of Landlord, which consent shall
not be unreasonably withheld.

         (b)  For any month in which the square footage of space used by Tenant
increases or decreases from the amount set forth on Exhibit B, the amount paid
with respect to the Premises shall be equitably apportioned to reflect Tenant's
actual utilization.

         (c)  If Tenant requires additional space due to an increase in the
number of Tenant's workforce at the Premises, then, at Tenant's request made on
or before May 1, 1997, Landlord will provide up to twenty-seven (27) additional
offices by relocating the Mask Technology group from Building 4 and renovating
the area at Landlord's expense.  Landlord shall have no obligation hereunder to
comply with any such request made after May 1, 1997.  Tenant shall reimburse
Landlord for the unamortized portion of any such expense to the extent that,
following such renovations, Tenant terminates this Lease or decreases the space
of the Premises prior to the Expiration Date.   Expansion efforts will commence
when Tenant establishes ten (10) open personnel requisitions for additional
employees and will be scheduled for completion on an all commercially reasonable
efforts basis within twelve (12) to sixteen (16) weeks.

         (d)  Upon substantial completion of such renovations (including the
issuance of any certificate of occupancy or temporary certificate of occupancy
required as a condition to Tenant's occupancy), such additional space shall be
added to the Premises and additional Base Rent of $2.65 per square foot per four
(4) week period shall be payable with respect to such additional space.  In such
event, the Landlord and Tenant shall execute an amendment to this Lease to
reflect the additional Premises and the additional Base Rent, but this Lease
shall remain unmodified in all other respects.

    8.   RIGHT TO RELOCATE.   

         (a)   Landlord reserves the right to reasonably relocate Tenant
employees as deemed necessary to provide proper segregation from Landlord
operations.  Such relocation shall be made only with the consent of Tenant,
which consent shall not be unreasonably withheld.      

         (b)  All relocation requested by Landlord shall be accomplished at
Landlord's sole expense and shall be performed in a manner that minimizes the
impact to Tenant's ongoing operations.  


                                          3





         (c)  Upon any such relocation, Landlord and Tenant shall execute an
amendment to this Lease to reflect such change, but this Lease shall remain
unmodified in all other respects, including the Base Rent payable hereunder.

    9.   AS-IS CONDITION.  Subject to the provisions of Section 7 of this
Lease, Tenant accepts the Premises and any and all fixtures and improvements
therein in their "as is" "where is" condition and acknowledges that (i) no
representation with respect to the condition of the Premises or any such
fixtures and improvements has been made to Tenant by or on behalf of Landlord,
and (ii) Landlord has no responsibility for improving the space for Tenant.

    10.  PERSONAL PROPERTY AND CONDITION AT TERMINATION.  The conference room
furniture, partitions and modular furniture in the Premises, including Building
4 and Building 9, shall be considered the sole property of Landlord and shall
not be removed by Tenant.  Chairs, detached file cabinets and all office
equipment shall be considered the personal property of Tenant.  On or before the
Termination Date, Tenant shall remove all of its personal property, including,
without limitation, its trade fixtures, from the Premises at its sole cost and
expense and shall leave the Premises broom clean and otherwise in the same
condition as it was on the date hereof, normal wear and tear and loss by
casualty or condemnation excepted.

    11.  DEFAULT BY TENANT.  Landlord shall notify Tenant of any default by
Tenant of Tenant's obligations under this Lease.  Tenant shall have ten (10)
days from its receipt of such notice to cure any monetary default and thirty
(30) days after receipt of such notice to cure any other default; provided that
with respect to non-monetary defaults which do not materially impair the value
of the Premises, Tenant may have such additional time to effect such cure as is
reasonably required as long as Tenant is diligently pursuing such cure.  Upon
the termination of the applicable grace period, Landlord may terminate this
Lease and exercise any and all other remedies available to it at law or in
equity with respect to this Lease.

    12.  INSURANCE.

         (a)  At all times during the Term of this Lease, Tenant shall maintain
(i) commercial general liability insurance (including, without limitation,
premises, independent contractors, contractual liability, and a broad form of
comprehensive general liability endorsement) with limits of not less than Three
Million Dollars ($3,000,000) combined for bodily injury, death and property
damage; (such amount of insurance to be increased from time to time as is
customary for insurance of such type to reasonably reflect inflation and other
matters); and (ii) casualty insurance on its personal property and equipment
which insurance may have deductible amounts which are consistent with Landlord's
historical deductible amounts with respect to such coverage on its personal
property and on the Buildings and the Premises.


                                          4




         (b)  At all times during the Term of this Lease, Landlord shall
maintain (i) commercial general liability insurance (including, without
limitation, premises, independent contractors, contractual liability, and a
broad form of comprehensive general liability endorsement) with limits of not
less than Three Million Dollars ($3,000,000) combined for bodily injury, death
and property damage (such amount of insurance to be increased from time to time
as is customary for insurance of such type to reasonably reflect inflation and
other matters); (ii) all risk extended fire and casualty insurance, written at
replacement cost value with replacement cost endorsements, insuring the
Buildings and Premises, exclusive of Tenant's personal property ("Landlord's
Casualty Policy"); and (iii) casualty insurance on its personal property and
equipment which insurance may have deductible amounts which are consistent with
Landlord's historical deductible amounts with respect to such coverage on its
personal property and on the Buildings and the Premises.

         (c)  All public liability insurance required by this Lease to be
maintained by Landlord or Tenant shall name the other party as an additional
insured.  Each party shall provide to the other current certificates of such
insurance as it is required to maintain.  Such certificates shall provide that
any change restricting or reducing any such coverage or the cancellation of any
policy under which any such certificate is issued shall not be valid except upon
twenty (20) days notice in writing to Landlord and Tenant of such change or
cancellation.  All such policies shall be obtained from responsible insurance
companies qualified to do business in the State of California and in good
standing therein.  Insofar as and to the extent that the following provisions
may be effective without invalidating or making it impossible to secure
insurance coverage obtainable from responsible insurance companies doing
business in the State of California (even though extra premium may result
therefrom), Landlord and Tenant mutually agree, and their insurance policies
shall provide, that with respect to any loss which is covered by insurance then
being carried by them, respectively, or which would be covered by insurance
policies required by this Lease if such policies had no deductible amount, the
one carrying or required to carry such insurance and suffering said loss
releases the other of and from any and all claims with respect to such loss; and
they further mutually agree that their respective insurance companies shall have
no right of subrogation against the other on account thereof, nor shall the
party suffering the loss have any claim against the other party with respect to
any such loss not covered by its insurance that would have been covered had
insurance policies maintained by the injured party had no deductible amount. 
This provision is intended to restrict each party (as permitted by law) to
recovery against insurance carriers to the extent of such coverage, and waive
fully, and for the benefit of each, any rights and/or claims which might give
rise to a right of subrogation in any insurance carrier.

         (d)  In the event that at any time during the Term of this Lease the
Premises or other portions of the improvements within which the Premises are
located shall be damaged or destroyed to any material degree in whole or in part
by fire or other cause, either Landlord or Tenant may elect to terminate this
Lease, but if neither party so elects, Landlord shall be required to repair and
restore the Premises and the improvements in which the Premises are located
within a reasonable time period.  During such time as the Premises, 

                                          5





as a result of such damage or destruction, cannot be occupied by Tenant, there
shall be an equitable reduction in the payment of Base Rent.  In any case where
a party has the right to elect to terminate this Lease in accordance with this
Section such party shall make such election by notice to the other party given
not later than sixty (60) days after the occurrence of the damage or destruction
giving rise to such election.  If either party elects to terminate as
hereinabove provided, then this Lease and the term thereof shall cease and come
to an end, and any unearned Base Rent or other charges paid in advance shall be
refunded to Tenant.

    13.  ENVIRONMENTAL.

         (a)  Landlord and Tenant acknowledge that there are environmental
conditions at, near or affecting the Property for which Landlord or one of its
affiliates is currently performing investigation, remediation or other response
actions (collectively, "Remediation").  Landlord covenants and agrees that
Remediation is being and will continue to be performed pursuant to and in
compliance with applicable federal, state, county and municipal laws, rules,
regulations, orders, permits and directives relating to human health or the
environment ("Environmental Laws"), and the performance of Remediation does not
and will not have an adverse effect on the Premises or unreasonably interfere
with the Tenant's use and/or operation thereat.  Landlord will retain full
responsibility for any violations of Environmental Laws and Remediation required
now or in the future relating to environmental conditions (including, but not
limited to responsibility for any fines and penalties) unless environmental
conditions or violations or Remediation results from Tenant's activities.

         (b)  In addition to indemnifications in Section 14 of this Lease and
in the Asset Purchase Agreement between Fairchild Semiconductor Corporation, as
Buyer, and National Semiconductor Corporation, as Seller, dated as of the date
hereof ("Purchase Agreement"), Landlord agrees to indemnify, defend and hold
Tenant harmless from and against any and all actions, demands, claims, losses,
damages, costs and liabilities and expenses (including, without limitation,
reasonable attorney's fees) (collectively, "Claims") asserted against, imposed
upon or incurred by Tenant which arise out of, result from or in any way relate
to (i) any environmental conditions existing at, on, under, about or migrating
to or from the Premises as of the commencement of this Lease, (ii) Landlord's
performance of Remediation (whether performed or required to be performed before
or after the commencement of the Lease), (iii) any violation of Environmental
Law prior to the date of this Lease, (including, without limitation, any
violation relating to the Remediation, the Premises or the Landlord's activities
thereat), and (iv) environmental conditions or violations of Environmental Laws
not caused by Tenant's activities, regardless of when such violations occur or
conditions arise.  Landlord agrees to respond on Tenant's behalf to such Claims
or, at Tenant's election, to pay the costs of Tenant's response.  In the event
that Landlord fails to comply with the obligations of this Section, Tenant, at
its sole discretion and notwithstanding anything to the contrary, shall have the
option to terminate this Lease. 

                                          6





         (c)  Landlord hereby waives and releases Tenant from any and all
claims, known and unknown, foreseen or unforeseen, which exist or may arise
under common or statutory environmental law, including the Comprehensive
Environmental Response, Compensation and Liability Act, as amended ("CERCLA") or
any other statutes now or hereafter in effect, except for those matters for
which Tenant is obligated to indemnify Landlord under this Lease.

         (d)  Tenant covenants and agrees to defend, indemnify and hold
Landlord harmless from and against any and all Claims that are asserted against
or incurred by Landlord or the Premises to the extent such Claims relate to or
arise out of any environmental condition caused by Tenant's activities at the
Premises, or Tenant's violation of any Environmental Law, (which violation was
not in existence prior to the date hereof), provided, however, that Tenant shall
not be obligated to indemnify Landlord for any Claim for which Landlord is
required to indemnify Tenant under this Lease.

         (e)  Tenant shall not use, store or bring upon the Premises any
chemicals or toxic or hazardous materials or substances of an type, without the
prior written consent of Landlord, which may be granted or denied in its sole
and absolute discretion.  Notwithstanding the foregoing, Tenant may, without
obtaining such consent, use, store and bring upon the Premises incidental
amounts of (i) those chemicals that, as of the date hereof, Tenant was using or
storing at the Premises in connection with the uses of the Premises permitted by
this Lease, and (ii) any other chemicals as become necessary or desirable for
Tenant to continue to use the Premises as permitted herein in the ordinary
course of its business.

    14.  INDEMNIFICATION.

         (a)  Tenant covenants and agrees, as its sole cost and expense and in
addition to any other right or remedy of Landlord hereunder, to indemnify and
save harmless Landlord from and against all loss, cost, expense, liability and

misconduct of Landlord or its agents, employees or contractors), including,
without limitation, reasonable attorneys' fees and court costs, arising from or
in connection with (i) Tenant's use, occupancy, operation and control of the
Premises, (ii) the conduct or management of any work, or any act or omission
done in or on the Premises by or under the direction or at the request of
Tenant, (iii) any breach or default on the part of Tenant in the payment of any
rent or performance of any covenant or agreement on the part of Tenant to be
performed pursuant to the terms of this Lease, or (iv) any act or negligence of
Tenant or any of its agents, contractors, servants, employees, licensees or
invitees.  The provisions of this Section shall survive the termination or
expiration of this Lease.

                                          7





         (b)  In the event that any action or proceeding is brought against
Landlord by reason of any claims covered by the foregoing indemnity, Tenant
will, upon notice from Landlord, resist or defend such action or proceeding by
counsel reasonably satisfactory to Landlord.  Landlord will not defend such
action or proceeding by counsel so long as Tenant is diligently doing so on
Landlord's behalf.  Landlord will give prompt notice to Tenant of any action or
proceeding brought against Landlord by reason of any claims covered by the
foregoing indemnity, together with copies of any documents served in connection
therewith, and Landlord will not settle any such claim without Tenant's written
consent.

         (c)  Landlord covenants and agrees, at its sole cost and expense and
in addition to any other right or remedy of Tenant hereunder, to indemnify and
save harmless Tenant from and against any and all loss, costs, expense,
liability and claims (but excluding any liability arising out of the negligence
or willful misconduct of Tenant or its agents, employees or contractors or the
failure by Tenant to comply with any provision of this Lease), including without
limitation, reasonable attorneys' fees and court costs, arising from and in
connection with (i) Landlord's use, ownership or control of the Buildings, (ii)
the conduct or management of any work, or any act or omission done in or on the
Buildings by or under the direction or at the request of Landlord, (iii) any
breach or default on the part of Landlord in the performance of any obligation
or covenant to be performed pursuant to the terms of this Lease, (iv) any act or
negligence of Landlord or any of its agents, contractors, servants, employees,
licensees or invitees, or (v) any failure of the Buildings to be or remain in
compliance with all laws, ordinances, orders and regulations affecting the
Buildings and the cleanliness, safety, accessibility, occupation and use of the
same, including without limitation, any Environmental Laws (other than
non-compliance resulting from acts or omissions of Tenant).  The provisions of
this Section shall survive the termination or expiration of this Lease.

         (d)  In the event that any action or proceeding is brought against
Tenant by reason of any claims covered by the foregoing indemnity, Landlord
will, upon notice from Tenant, resist or defend such action or proceeding by
counsel reasonably satisfactory to Tenant.  Tenant will not defend such action
or proceeding so long as Landlord is diligently doing so on Tenant's behalf. 
Tenant will give prompt notice to Landlord of any action or proceeding brought
against Tenant by reason of any claims covered by the foregoing indemnity,
together with copies of any documents served on Tenant in connection therewith,
and Tenant will not settle any such claim without Landlord's written consent.

    15.  ACCESS.  Tenant hereby covenants and agrees that it will not and will
take all necessary steps to prevent its employees, agents and invitees from
entering into or upon any portion of the Facility restricted by Landlord (any
such portion is hereinafter referred to as a "Restricted Access Area"). 
Following the execution of this Lease, Landlord shall provide Tenant with a Site
Plan of the Facility indicating all of the Restricted Access Areas.  Tenant
acknowledges that it is the intent of the parties that Tenant shall only have
access to those parts of the Facility as are reasonably necessary or desirable
for its use and enjoyment


                                          8




of the Premises and of the services available to it hereunder or under any other
agreement between Landlord and Tenant and dated of even date herewith.

    16.  ASSIGNMENT AND SUBLETTING.  

         (a)  Subject to the provisions of Section 16(c) below.  Tenant may not
assign this Lease or sublet the Premises or any part thereof without obtaining
the consent of Landlord therefor, which consent shall not be unreasonably
withheld, and without first offering to Landlord the right to accept an
assignment or sublease of the Premises on the same terms that Tenant proposed to
assign or sublease to a third party.  If Landlord fails to accept or reject
Tenant's offer of assignment or sublease of the Premises within fifteen (15)
days of receipt of the making of such offer, then Landlord shall be deemed to
have rejected such offer.  If Landlord fails to accept or reject Tenant's
request for consent to the assignment or sublease of the Demised Premised by a
third party within thirty (30) days of receipt of such request for consent, the
Landlord shall be deemed to have consented to the proposed assignment or
sublease to such third party.  Any attempted assignment or sublease in violation
of this Section shall be void and shall confer no rights on the purported
assignee.  The consent by Landlord to an assignment or subletting shall not
relieve Tenant from primary liability hereunder or from the obligation to obtain
the express consent in writing of Landlord to any future assignment or
subletting.

         (b)   Notwithstanding the foregoing, Tenant shall have the right to
assign this Lease or to grant a leasehold mortgage on Tenant's leasehold
interest under this Lease as security to any lender making a loan to Tenant for
Tenant's business.  After receiving written notice from any person, firm, or
other entity, stating that it holds a mortgage or security interest on Tenant's
leasehold interest under this Lease, Landlord shall, so long as such mortgage is
outstanding, be required to give to such holder the same notices as are required
to be given to Tenant under the terms of this Lease, but such notices may be
given by Landlord to Tenant and such holder concurrently.  It is further agreed
that such holder shall have the same opportunity to cure any default, and the
same time within which to effect such curing, as is available to Tenant; and if
necessary to cure such a default, such holder shall have access to the Premises
and the Buildings.  Landlord further agrees to recognize such holder, its
successors or assigns, as successor Tenant under this Lease in the event of the
foreclosure, or transfer in lieu of foreclosure, of such lender's security
interest or mortgage, provided that such holder or its successor or assign cures
all defaults of Tenant hereunder that can be cured by the expenditure of money.

         (c)  No sale of stock or transfer of any ownership interest of Tenant
shall be deemed to be an assignment of this Lease.  Tenant shall have the right
to sublease or assign this Lease or Tenant's rights hereunder in whole or in
part, to any Affiliated Entity as hereinafter defined, without the consent of
Landlord and without first offering to assign or sublet to Landlord, and the
provisions of Subsection 16(a) shall not apply to any such assignment or
sublease.  The term "Affiliated Entity" shall mean any limited liability
company, corporation, partnership, joint venture or other entity (x) of which
Tenant holds 

                                          9





one hundred percent (100%) of the voting authority or ownership interests of
Tenant; or (y) any entity in which one hundred percent (100%) of the voting
authority or ownership interests are held by persons or entities holding one
hundred percent (100%) of the ownership interests or voting authority of Tenant.
Tenant shall promptly notify Landlord of the occurrence of any such sublease or
assignment of this Lease.  

    17.  ALTERATIONS.  Tenant shall not make any alterations to the Premises
without the prior written consent of Landlord, which shall not be unreasonably
withheld or delayed.

    18.  COMPLIANCE WITH LAWS.  Tenant shall use and occupy the Premises in
accordance with all applicable federal, state, county and municipal laws, rules
and regulations and all rules and regulations imposed by Landlord.

    19.  QUIET ENJOYMENT.  Landlord covenants and agrees that Tenant, upon
performing the terms and conditions of this Lease to be performed by Tenant
shall have peaceable and quiet enjoyment and possession of the Premises during
the term without interruption by Landlord or its successors or assigns or any
other person or company lawfully claiming by or through it.  

    20.  SUBORDINATION.  Tenant accepts this Lease subject and subordinate in
all respects to any mortgage which may now or hereafter be placed on or affect
the fee interest in the Property and/or Landlord's interest therein (each a
"Mortgage"), and to each advance made, or hereafter to be made, under any
Mortgage, and to all renewals, modifications, consolidations, replacements,
extensions and substitutions of and for any Mortgage, provided holder of any
Mortgage (each a "Mortgagee") shall agree not to disturb Tenant's use and
occupancy of the Premises so long as Tenant is not in substantial default
hereunder.  Notwithstanding the aforesaid, if any Mortgagee elects to have
Tenant's interest in this Lease be superior to any Mortgage held by it, then by
notice to Tenant from such Mortgagee this Lease shall be deemed superior to such
Mortgage, whether this Lease is executed before or after same.  

         This Section 20 shall be self-operative and no further instrument of
subordination shall be required.  In confirmation of such subordination,
however, Tenant shall execute and deliver promptly any certificate that Landlord
and/or any Mortgagee or their respective successors in interest may request. 
Tenant hereby constitutes and appoints Landlord and/or any mortgagee and/or
their respective successors in interest as Tenant's attorney-in-fact to execute
and deliver any such certificate or certificates for and on behalf of Tenant if
Tenant shall fail to do so within ten (10) days after written request therefor.

    21.  EMINENT DOMAIN.

         (a)  If, after the execution prior to the expiration of the Term
hereof, the whole of the Premises shall be taken under the power of eminent
domain, then this Lease 

                                          10





and the term thereof shall cease and terminate as of the date of taking of
possession by the taking authority, and any unearned rent or other charges, if
any, paid in advance shall be refunded to Tenant.

         (b)  If at any time during the Term of this Lease, a portion of the
Premises shall be so taken under the power of eminent domain so as to render the
Premises untenantable, then Landlord, at its own cost and expense, may, unless
this Lease is terminated pursuant to the provisions of this Section, repair and
restore the Premises, to the extent possible within the limits of damages paid
to Landlord, to substantiate the condition at which they were immediately prior
to such taking and within the period of time which, under all prevailing
circumstances, shall be reasonable, or it may terminate this Leases.  During
such time as the Premises as a result of such taking cannot be occupied by
Tenant, the rent shall be equitably adjusted.  Upon termination as aforesaid by
Landlord, this Lease and the term thereof shall cease and come to an end, and
any unearned Base Rent or other charges paid in advance shall be refunded to
Tenant.

         (c)  The entire award for any taking shall belong to Landlord without
any deduction for any leasehold estate or interest now or hereafter vested in
Tenant.

    22.  NOTICES.  All notices given under this Lease shall be sent in writing
through certified mail, or via a reputable overnight carrier providing evidence
of receipt (e.g., Federal Express), postage prepaid, to Tenant and to Landlord
at their respective addresses shown on Exhibit C attached hereto or to such
other addresses which may be designated in writing from time to time.

    23.  BROKERS.  Landlord and Tenant warrant and represent that they have
dealt with no real estate broker in connection with this Lease and that no
broker is entitled to any commission on account of this Lease.  Each of Landlord
and Tenant shall indemnify and hold harmless the other from any loss, cost,
damage or expense, including reasonable attorney fees, which the other shall
incur on account of the falsity of the maker's foregoing representation and
