 ------------                                                              
(A) income, excess profits or other taxes of Landlord (or Lender) which are
determined on the basis of Landlord's (or Lender's) net income or net worth
(unless such taxes are in lieu of or a substitute for any other tax, assessment
or other charge upon or with respect to the Leased Premises which, if it were in

                                       11
<PAGE>
 
occurring after the tenth (10th) Lease Year, but not with respect to any change
of ownership occurring prior thereto. If any Imposition may be paid in
installments without interest or penalty, Tenant shall have the option to pay
such Imposition in installments; in such event, Tenant shall be liable only for
those installments which accrue or become due and payable during the Term.
Tenant shall prepare and file all tax reports required by governmental
authorities which relate to the Impositions. Tenant shall deliver to Landlord
(1) copies of all settlements and notices pertaining to the Impositions which
may be issued by any governmental authority within twenty (20) days after
Tenant's receipt thereof, (2) satisfactory evidence (which may be written notice
from a tax service acceptable to Landlord and Lender) of payment of all taxes
required to be paid by Tenant hereunder no later than thirty (30) days following
the date the same would become delinquent, showing the same to have been paid
prior to delinquency and (3) receipts for payment of all other Impositions
promptly following Landlord's request therefor.

               (b)  Landlord shall have the right, (i) following the occurrence
of an Event of Default with respect to Escrow Charges described in clause (A) of
the following sentence and (ii) if Landlord or Lender determines that the Leased
Premises are not being maintained in accordance with current standards for
similarly situated office buildings prudently managed so that the condition of
the Leased Premises is not as required by Paragraph 12 (a) hereof, to require
Tenant to pay to Landlord, or to Lender if directed by Landlord, an additional
monthly sum (each an "Escrow Payment") sufficient to pay the Escrow Charges (as
                      --------------             
hereinafter defined) as they become due. As used herein, "Escrow Charges" shall
                                                          --------------  
mean (A) real estate taxes on the Leased Premises or payments in lieu thereof
and premiums on any insurance required by this Lease, and (B) amounts required
by a Lender on the basis of an inspection of the Leased Premises or as otherwise
reasonably determined by Lender which shall be deposited in a reserve or
reserves such as a capital improvement reserve, a replacement reserve and/or a
repair reserve (such amounts in this clause (B) collectively referred to as
"Reserve Funds"). Landlord shall determine the amount of the Escrow Charges and
of each Escrow Payment. As long as the Escrow Payments are being held by
Landlord the Escrow Payments shall not be commingled with other funds of
Landlord or other Persons and interest thereon shall accrue for the benefit of
Tenant from the date such monies are received and invested until the date such
monies are disbursed to pay Escrow Charges. If the Escrow Payments are held by
the Lender, they shall be held and administered in accordance with Lender's
customary procedures for similar accounts. Landlord shall apply the Escrow
Payments to the payment of the Escrow Charges in such order or priority as
Landlord shall determine or as required by law; provided, however, that any
Reserve Funds shall only be used for improvements or repairs for which such
Reserve Funds have been deposited, and any remaining balance of any such Reserve
Funds shall be disbursed to Tenant at such time as such improvements or repairs
have been completed so long as no Event of Default then exists. If at any time
the Escrow Payments theretofore paid to Landlord shall be insufficient for the
payment of the Escrow Charges, Tenant, within fifteen (15) days after Landlord's
demand therefor, shall pay the amount of the deficiency to Landlord.

Lender's request provide Landlord and Lender with copies of all filings which
Tenant is required to submit to governmental agencies and all permits, licenses
and certificates which Tenant is required to obtain from governmental agencies,
in both cases with respect to the Leased Premises. Tenant shall give prompt
notice to Landlord and Lender of receipt by Tenant of any notice related to any
Legal Requirements and of the commencement of any proceedings or investigations
which relate to compliance with Legal Requirements. Any and all reports prepared
for or by Landlord with respect to the Leased Premises shall be for the sole
benefit of Landlord and Lender and no other Person shall have the right to rely
on any such reports.

               (b)   Tenant, at its sole cost and expense, will at all times
promptly and faithfully abide by, discharge and perform all of the covenants,
conditions and agreements contained in any Easement Agreement on the part of
Landlord or the occupier to be kept and performed thereunder and shall enter
into access agreements for the purposes described in the foregoing Paragraph
10(a), such agreements to be subject to the reasonable approval of Landlord.
Tenant will not alter, modify, amend or terminate any Easement Agreement, give
any consent or approval thereunder, or enter into any new Easement Agreement
without, in each case, the prior written consent of Landlord, which consent
shall not be unreasonably withheld (provided, however, that Landlord hereby
consents to the Site Access Agreement dated March 21, 1997 between AMD
International Sales & Service, Ltd., and Advanced Micro Devices, Inc. and 999
Arques Corporation and consents to the Site Access Agreement dated March 17,
1997 between AMD International Sales & Service, Ltd. and Advanced Micro Devices,
Inc. and CAE Electronics Inc.). Landlord shall cooperate with Tenant with
respect to the creation of easements and/or rights of way for ingress and egress
to and from the Leased Premises or in favor of municipal or other governmental
authorities or public service or utility companies for the installation of water
lines, sewers, electricity, telephone, gas, steam or easements for other
facilities and utilities reasonably required for the use and occupancy of the
Leased Premises.

               (c)   Upon prior written notice from Landlord, Tenant shall
permit such persons as Landlord may designate (who shall be a regional or
national environmental audit firm designated by Lender and who shall be Eckland
Consulting or another firm reasonably acceptable to Tenant) ("Site Reviewers")
                                                              --------------
to visit the Leased Premises and perform environmental site investigations,
audits and assessments ("Site Assessments") on the Leased Premises for the
                         ----------------                
purpose of determining whether there exists on the Leased Premises any
Environmental Violation or any condition which could result in any Environmental
Violation. Such Site Assessments may include both above and below the ground
testing for Environmental Violations and such other tests as may be necessary,
in the reasonable opinion of the Site Reviewers, to conduct the Site
Assessments; provided, however, that any such testing to be undertaken in
connection with any Site Assessment shall be conducted in such a manner as to
minimize any interference with Tenant's business operations at the Leased
Premises; and provided, further, that such Site Assessments shall not be
conducted more frequently than once every 24 months unless Landlord is required
to undertake a Site Assessment as a condition of obtaining financing or
refinancing, or in connection with a sale of the Leased Premises or if required
by a Lender. In such cases, the Site Assessment may be conducted by Landlord at
any time. The Site Assessment shall be limited to a visual inspection and review
of records unless (i) Landlord or Lender has reasonable cause to believe that an
Environmental Violation exists at the Leased Premises; (ii) intrusive testing is
required to be undertaken as a condition of Landlord obtaining financing or
refinancing or of a proposed sale of the Leased Premises or if required by a
Lender; or (iii) such testing is conducted within nine (9) months of the
expiration of the Lease Term, in which case such Site Assessment may include the
testing described above. Tenant shall supply to the Site Reviewers such
historical and operational information regarding the Leased Premises as may be
reasonably requested by the Site Reviewers to facilitate the Site Assessments,
and shall make available for meetings with the Site Reviewers appropriate
personnel having 

                                       13
<PAGE>
 
knowledge of such matters. The reasonable cost of performing and reporting Site
Assessments shall be paid by Tenant, except that Tenant shall not be responsible
to pay the cost of performing and reporting Site Assessments required in
connection with any sale of the Leased Premises.

               (d)   If an Environmental Violation (other than ground water
contamination which has migrated to the Leased Premises from off-site sources
unless Tenant is or has been required by a governmental authority to remediate
such contamination) occurs or is found to exist and, in Landlord's reasonable
judgment, the cost of remediation of, or other response action with respect to,
the same is likely to exceed $1,000,000 and at the time of such remediation
Tenant does not have a publicly traded, unsecured senior debt rating of "Baa2"
or better from Moody's or a rating of "BBB" or better from S&P, Tenant shall
provide to Landlord, within thirty (30) days after Landlord's request therefor,
adequate financial assurances that Tenant will effect such remediation in
accordance with applicable Environmental Laws. Such financial assurances shall
be a bond or letter of credit reasonably satisfactory to Landlord in form and
substance and in an amount equal to or greater than Landlord's reasonable
estimate, based upon a Site Assessment performed pursuant to Paragraph 10(c), of
the anticipated cost of such remedial action.

               (e)   Notwithstanding any other provision of this Lease, if an
Environmental Violation occurs (other than ground water contamination which has
migrated to the Leased Premises from off-site sources unless Tenant is or has
been required by a governmental authority to remediate such contamination) or is
found to exist and the Term would otherwise terminate or expire, then, at the
option of Landlord, the Term shall be automatically extended beyond the date of
termination or expiration and this Lease shall remain in full force and effect
beyond such date until the earlier to occur of (i) the completion of all
remedial action in accordance with applicable Environmental Laws or (ii) one (1)
year from the date on which this Lease would otherwise terminate or expire so
long as on or before such date Tenant deposits with Landlord an amount
determined by the Site Reviewer to be reasonably required to complete such
remediation.

               (f)   If Tenant fails to correct any Environmental Violation
which occurs or is found to exist, Landlord shall have the right (but no
obligation) to take any and all actions as Landlord shall deem reasonably
necessary or advisable in order to cure such Environmental Violation.

               (g)   Tenant shall notify Landlord promptly after becoming aware
of any Environmental Violation (or alleged Environmental Violation) or
noncompliance with any of the covenants contained in this Paragraph 10 and shall
forward to Landlord immediately upon receipt thereof copies of all orders,
reports, notices, permits, applications or other communications relating to any
such violation or noncompliance.

               (h)   All future leases, subleases or concession agreements
relating to the Leased Premises entered into by Tenant shall contain covenants
of the other party not to at any time (i) cause any Environmental Violation to
occur or (ii) permit any Person occupying the Leased Premises through said
subtenant or concessionaire to cause any Environmental Violation to occur.
        
         11.   Liens; Recording.
               ---------------- 

               (a)   Tenant shall not, directly or indirectly whether by any act
or omission, create or permit to be created or to remain and shall promptly
discharge or remove any lien, levy or encumbrance on any of the Leased Premises
or on any Rent or any other sums payable by Tenant under this Lease, other than
any Mortgage or Assignment, the Permitted Encumbrances and any mortgage, lien,
encumbrance or other charge created by or resulting from 

                                       14

BE LIABLE FOR ANY LABOR, SERVICES OR MATERIALS FURNISHED OR TO BE FURNISHED TO
TENANT OR TO ANYONE HOLDING OR OCCUPYING ANY OF THE LEASED PREMISES THROUGH OR
UNDER TENANT, AND THAT NO MECHANICS' OR OTHER LIENS FOR ANY SUCH LABOR, SERVICES
OR MATERIALS SHALL ATTACH TO OR AFFECT THE INTEREST OF LANDLORD IN AND TO ANY OF
THE LEASED PREMISES. LANDLORD MAY AT ANY TIME, AND AT LANDLORD'S REQUEST TENANT
SHALL PROMPTLY, POST ANY NOTICES ON THE LEASED PREMISES REGARDING SUCH NON-
LIABILITY OF LANDLORD.

               (b)   Landlord and Tenant shall execute, acknowledge, deliver and
record, file or register (collectively, "record") all such instruments as may be
                                         ------
required or permitted by any present or future Law in order to evidence the
respective interests of Landlord and Tenant in the Leased Premises, and shall
cause a memorandum of this Lease (or, if such a memorandum cannot be recorded,
this Lease), and any supplement hereto or thereto, to be recorded in such manner
and in such places as may be required or permitted by any present or future Law
in order to protect the validity and priority of this Lease.

         12.   Maintenance and Repair.

Initial Lender and fit to be used for their intended use in accordance with the
better of the practices generally recognized as then acceptable by other
companies in its industry or the then current standards for similarly situated
office buildings prudently managed, and, in the case of the Equipment, in as
good mechanical condition as it was on the later of the date hereof or the date
of its installation, except for ordinary wear and tear. Tenant shall take every
other action necessary or appropriate for the preservation and safety of the
Leased Premises. Tenant shall make all Alterations of every kind and nature,
whether foreseen or unforeseen, which may be required to comply with the
foregoing requirements of this Paragraph 12(a) whether disclosed by Landlord or
Tenant or as a consequence of any inspection by Lender promptly after the need
for such Alterations becomes known to Landlord or Tenant. Any Alterations
required to be made as a result of any inspection by Lender shall be commenced
within thirty (30) days from receipt of notice from Landlord or Lender and
thereafter diligently pursued to completion. Landlord shall not be required to
make any Alteration, whether foreseen or unforeseen, or to maintain any of the
Leased Premises or Adjoining Property in any way, and Tenant hereby expressly
waives any right which may be provided for in any Law now or hereafter in effect
to make Alterations at the expense of Landlord or to require Landlord to make
Alterations. Any Alteration made by Tenant pursuant to this Paragraph 12 shall
be made in conformity with the provisions of Paragraph 13 and the requirements
of any Lender.

               (b)   If any Improvement, now or hereafter constructed, shall (i)
encroach upon any setback or any property, street or right-of-way adjoining the
Leased Premises, (ii) violate the provisions of any restrictive covenant

         13.   Alterations and Improvements.
               ---------------------------- 

               (a)   Tenant shall have the right, without having obtained the
prior written consent of Landlord and Lender and provided that no Event of
Default then exists, to make (i) non-structural Alterations that do not affect
the structural integrity of the Improvements, or adversely affect any of the
mechanical or electrical systems of the Improvements, (ii) Alterations that are
required in order to comply with Law, (iii) structural Alterations or a series
of related structural Alterations that, as to any such structural Alterations or

that do not affect the structural integrity of the Improvements or adversely
affect any of the mechanical or electrical systems in the Improvements and (iv)
to install Equipment in the Improvements or accessions to the Equipment that, as
to such Equipment or accessions, do not cost in excess of $500,000, so long as
at the time of construction or installation of any such Equipment or Alterations
no Event of Default exists and the value and utility of the Leased Premises is
not diminished thereby. If the cost of any structural Alterations, series of
related structural Alterations, Equipment or accessions thereto is in excess of
$500,000, the prior written approval of Landlord and Lender shall be required,
such approval not to be unreasonably withheld or delayed. Tenant shall not
construct upon the Land any additional buildings without having first obtained
the prior written consent of Landlord and Lender.

               (b)   If Tenant makes any Alterations pursuant to this Paragraph
13 or Paragraph 36 or as required by Paragraph 12 or 17 (such Alterations and
actions being hereinafter collectively referred to as "Work"), whether or not
                                                       ----

Work shall be performed by Tenant in a good and workmanlike manner, (iii) all
such Work shall be expeditiously completed in compliance with all Legal
Requirements, (iv) all such Work shall comply with the Insurance Requirements,
(v) if any such Work involves the replacement of Equipment or parts thereto, all
replacement Equipment or parts shall have a value and useful life equal to the
greater of (A) the value and useful life on the date hereof of the Equipment
being replaced or (B) the value and useful life of the Equipment being replaced
immediately prior to the occurrence of the event which required its replacement,
(vi) Tenant shall promptly discharge or remove all liens filed against any of
the Leased Premises arising out of such Work, (vii) Tenant shall procure and pay

other Person thereto or therein, and (ix) with respect to Alterations or a
series of related Alterations that cost in excess of $500,000, Tenant shall
comply, to the extent reasonably requested by Landlord or required by this
Lease, with the provisions of Paragraph 19(a), whether or not such Work involves
restoration of the Leased Premises.

         14.   Permitted Contests.  Notwithstanding any other provision of this
               ------------------                                              
Lease, Tenant shall not be required to (a) pay any Imposition, (b) discharge or
remove any lien referred to in Paragraph 11 or 13 or (c) take any action with
respect to any encroachment, violation, hindrance, obstruction or impairment
referred to in Paragraph 12(b) (such non-compliance with the terms hereof being
hereinafter referred to collectively as "Permitted Violations"), so long as at
                                         --------------------                 
the time of such contest no Event of Default exists and so long as Tenant shall
contest, in good faith, the existence, amount or validity thereof, the amount of
the damages caused thereby, or the 

                                       16
<PAGE>
 
extent of its or Landlord's liability therefor by appropriate proceedings which
shall operate during the pendency thereof to prevent or stay (i) the collection
of, or other realization upon, the Permitted Violation so contested, (ii) the
sale, forfeiture or loss of any of the Leased Premises or any Rent to satisfy or
to pay any damages caused by any Permitted Violation, (iii) any interference
with the use or occupancy of any of the Leased Premises, (iv) any interference

any insurance policy or a statement by the carrier that coverage will be denied.
Tenant shall provide Landlord security which is satisfactory, in Landlord's
reasonable judgment, to assure that such Permitted Violation is corrected,
including all Costs, interest and penalties that may be incurred or become due
in connection therewith. While any proceedings which comply with the
requirements of this Paragraph 14 are pending and the required security is held
by Landlord, Landlord shall not have the right to correct any Permitted
Violation thereby being contested unless Landlord is required by law to correct
such Permitted Violation and Tenant's contest does not prevent or stay such
requirement as to Landlord. Each such contest shall be promptly and diligently
prosecuted by Tenant to a final conclusion, except that Tenant, so long as the
conditions of this Paragraph 14 are at all times complied with, has the right to
attempt to settle or compromise such contest through negotiations. Tenant shall
pay any and all losses, judgments, decrees and Costs in connection with any such
contest and shall, promptly after the final determination of such contest, fully
pay and discharge the amounts which shall be levied, assessed, charged or
imposed or be determined to be payable therein or in connection therewith,
together with all penalties, fines, interest and Costs thereof or in connection
therewith, and perform all acts the performance of which shall be ordered or
decreed as a result thereof. No such contest shall subject Landlord to the risk
of any civil or criminal liability.

         15.   Indemnification.
               --------------- 

               (a)   With respect to any action or event which arises or occurs
prior to the expiration of the Term or any earlier termination of this Lease
and/or any consequences thereof, whether ascertainable prior to or at any time
after such expiration of the Term or earlier termination of the Lease, Tenant
shall pay, protect, indemnify, defend, save and hold harmless Landlord, Lender
and all other Persons described in Paragraph 30 (each an "Indemnitee") from and

law or in equity, arising from (i) any matter pertaining to the acquisition (or
the negotiations leading thereto), ownership, use, non-use, occupancy,
operation, condition, design, construction, maintenance, repair or restoration
of the Leased Premises or Adjoining Property, (ii) any casualty in any manner
arising from the Leased Premises or Adjoining Property, whether or not
Indemnitee has or should have knowledge or notice of any defect or condition
causing or contributing to said casualty, (iii) any violation by Tenant of any
provision of this Lease, any contract or agreement relating to the Leased
Premises to which Tenant is a party, any Legal Requirement or any Permitted
Encumbrance or any encumbrance Tenant consented to or any provision of the
Mortgage or Assignment that is binding upon Tenant or (iv) any alleged,
threatened or actual Environmental Violation, including (A) liability for
response costs and for costs of removal and remedial action incurred by the
United States Government, any state or local governmental unit or any other

including the reasonable costs of assessing such injury, destruction or loss,
incurred pursuant to Section 107 of CERCLA, or any successor section or act or
provision of any similar state or local Law, (B) liability for costs and
expenses of abatement, correction or clean-up, fines, damages, response costs or
penalties which arise from the provisions of any of the other Environmental Laws
and (C) liability for personal injury or property damage arising under 

                                       17

maintenance of a public or private nuisance or for carrying on of a dangerous
activity.

               (b)   In case any action or proceeding is brought against any
Indemnitee by reason of any such claim, (i) Tenant may, except in the event of a
conflict of interest or a dispute between Tenant and any such Indemnitee or
during the continuance of an Event of Default, retain its own counsel and defend
such action (it being understood that Landlord may, at its own cost, employ
counsel of its choice to monitor the defense of any such action) and (ii) such
Indemnitee shall notify Tenant to resist or defend such action or proceeding by
retaining counsel reasonably satisfactory to such Indemnitee, and such
Indemnitee will cooperate and assist in the defense of such action or proceeding
if reasonably requested so to do by Tenant. In the event of a conflict of
interest or dispute or during the continuance of an Event of Default, Landlord
shall have the right to select counsel, and the reasonable cost of such counsel
shall by paid by Tenant.

respect to any action or event which arises or occurs prior to the expiration of
the Term or any earlier termination of this Lease and/or the consequences
thereof, shall survive any termination, expiration or rejection in bankruptcy of
this Lease.

         16.   Insurance.
               --------- 

               (a)   Tenant shall maintain the following insurance on or in
connection with the Leased Premises:

                     (i)     Insurance against physical loss or damage to the
Improvements and Equipment as provided under a standard "All Risk" property

Endorsements and shall contain deductibles as may be recommended by Tenant's
insurance broker and approved by Landlord and Lender, such approval not to be
unreasonably withheld and in any event not less than $100,000. In addition,

estate in addition to the Leased Premises) of not less than $25,000,000 with a
deductible equal to the lesser of $10,000,000 or 5% of the casualty loss,
provided that proceeds received from any earthquake casualty in an amount equal
to the product of the probable maximum loss factor for the Improvements
multiplied by the replacement cost of the Improvements (but in no event more
than the cost of the restoration of the Improvements) shall be allocated by
Tenant for restoration of the Leased Premises prior to allocation of such
proceeds to restoration of any other improvements insured under such policy.

                     (ii)    Commercial General Liability Insurance (including
but not limited to Incidental Medical Malpractice and Host Liquor Liability) and

Premises, in an amount not less than $15,000,000 per occurrence/annual aggregate
and all other coverage extensions that are usual and customary for properties of
this size and type provided, however, that the Landlord shall have the right to
require such higher limits as may be reasonable and customary for properties of
this size and type.

                     (iii)   Workers' compensation insurance covering employees
of Tenant in connection with their employment on or about any of the Leased
Premises for which claims for death, disease or bodily injury may be asserted
against Landlord, Tenant or any of the Leased Premises or, in lieu of such
Workers' Compensation Insurance, a program of 

                                       18
<PAGE>
 
self-insurance complying with the rules, regulations and requirements of the
appropriate agency of the State.

sufficient to cover 100% of the period of indemnity not less than eighteen (18)
months from time of loss. Such insurance shall name Landlord as loss payee
solely with respect to Rent payable to or for the benefit of Landlord as its
interest appears under this Lease.

                     (vi)    During any period in which substantial Alterations

the total completed value including any "soft costs" with respect to the
Improvements being altered or repaired (on a completed value, non-reporting
basis), replacement cost of work performed and equipment, supplies and materials
furnished in connection with such construction or repair of Improvements or
Equipment, together with such "soft cost" endorsements and such other
endorsements as Landlord may reasonably require and general liability, worker's
compensation and automobile liability insurance with respect to the Improvements
being constructed, altered or repaired.

                     (vii)   Such other insurance (or other terms with respect
to any insurance required pursuant to this Paragraph 16, including without
limitation amounts of coverage, deductibles, form of mortgagee clause) on or in
connection with any of the Leased Premises as Landlord or Lender may reasonably
require, which at the time is usual and commonly obtained in connection with
properties similar in type of building size, use and location to the Leased
Premises.

               (b)   The insurance required by Paragraph 16(a) shall be written
by one or more (i) domestic primary insurer(s) having an investment grade rating
of "AA" or a comparable claims paying ability assigned by S&P or equivalent
credit rating agency approved by Landlord and Lender, and approved to write
insurance policies by the State Insurance Department for the State or (ii) such
other insurer(s) as may be otherwise approved by Landlord and Lender, such
approval not to be unreasonably withheld. The insurance policies (i) shall be
for such terms as Landlord may reasonably approve and (ii) shall be in amounts
sufficient at all times to satisfy any coinsurance requirements thereof. The
insurance referred to in Paragraphs 16(a)(i), 16(a)(iv) and 16(a)(vi) shall name
Landlord as Owner and Lender as loss payee and Tenant as its interest may
appear. The insurance referred to in Paragraph 16(a)(ii) shall name Landlord and
Lender as additional insureds, and the insurance referred to in Paragraph
16(a)(v) shall name Landlord (or Lender, if requested by Landlord) as loss payee
to the extent provided in Paragraph 16(a)(v). If said insurance or any part
thereof shall expire, be withdrawn, become void, voidable, unreliable or unsafe
for any reason, including a breach of any condition thereof by Tenant or the
failure or impairment of the capital of any insurer, or if for any other reason
whatsoever said insurance shall become reasonably unsatisfactory to Landlord,
Tenant shall immediately obtain new or additional insurance reasonably
satisfactory to Landlord.

               (c)   Each insurance policy referred to in clauses (i), (iv), (v)
and (vi) of Paragraph 16(a) shall contain standard non-contributory mortgagee
clauses in favor of and acceptable to Lender. Each policy required by any
provision of Paragraph 16(a), except clause (iii) thereof, shall provide that it
may not be cancelled or terminated, substantially modified or allowed to lapse
on any renewal date except after thirty (30) days' prior notice to Landlord and
Lender. Each such policy shall also provide that any loss otherwise payable
thereunder shall be 

                                       19
<PAGE>
 
payable notwithstanding (i) any act or omission of Landlord or Tenant which
might, absent such provision, result in a forfeiture of all or a part of such
insurance payment, (ii) the occupation or use of any of the Leased Premises for
purposes more hazardous than those permitted by the provisions of such policy,

any provision of the Mortgage, Note, Assignment or other document evidencing or
securing the Loan upon the happening of an event of default therein or (iv) any
change in title to or ownership of any of the Leased Premises.

               (d)   Tenant shall pay as they become due all premiums for the
insurance required by Paragraph 16(a) (and in any event not less than 30 days
prior to cancellation for non-payment), shall renew or replace each policy and
deliver to Landlord evidence of the renewal or replacement of each such policy
prior to the stated expiration thereof (which evidence may consist of a binder,
certificate or replacement policy) and, upon receipt shall promptly deliver to
Landlord all original certificates of insurance.

               (e)   Anything in this Paragraph 16 to the contrary
notwithstanding, any insurance which Tenant is required to obtain pursuant to
Paragraph 16(a) may be carried under a "blanket" or umbrella policy or policies
covering other properties or liabilities of Tenant, provided that such "blanket"
or umbrella policy or policies otherwise comply with the provisions of this
Paragraph 16 and provided further that Tenant shall provide to Landlord a
Statement of Values which shall be reviewed annually and amended as necessary
based on Replacement Cost Valuations. A certified copy of each such "blanket" or
umbrella policy shall promptly be delivered to Landlord, or if requested by
Landlord, to Lender.

               (f)   Tenant shall promptly comply with and conform to (i) all
provisions of each insurance policy required by this Paragraph 16 and (ii) all
requirements of the insurers thereunder applicable to Landlord, Tenant or any of
the Leased Premises or to the use, manner of use, occupancy, possession,
operation, maintenance, alteration or repair of any of the Leased Premises, even
if such compliance necessitates Alterations or results in interference with the
use or enjoyment of any of the Leased Premises.

               (g)   Tenant shall not carry separate insurance concurrent in
form or contributing in the event of a Casualty with that required in this
Paragraph 16 unless (i) Landlord and Lender are included therein as named
insureds, with loss payable as provided herein, and (ii) such separate insurance
complies with the other provisions of this Paragraph 16. Tenant shall promptly
notify Landlord of such separate insurance and shall deliver to Landlord a
certified copy of policies thereof.

               (h)   All policies shall contain effective waivers by the carrier
against all claims for insurance premiums against Landlord and Lender and shall
contain full waivers of subrogation against the Landlord and Lender.

               (i)  All proceeds of insurance payable under clause (v) with
respect to the Rent shall be payable to Landlord or, if required by the
Mortgage, to Lender. Proceeds of insurance required under clauses (i) and (iv)

         17.   Casualty and Condemnation.
               ------------------------- 

               (a)   If any Casualty to the Leased Premises occurs, Tenant shall
give Landlord and Lender immediate notice thereof. So long as no Event of
Default exists Tenant is 

                                       20
<PAGE>
 
hereby authorized to adjust, collect and compromise all claims under any of the
insurance policies required by Paragraph 16(a) and to execute and deliver on
behalf of Landlord all necessary proofs of loss, receipts, vouchers and releases
required by the insurers and Landlord shall have the right to join with Tenant
therein. Any final adjustment, settlement or compromise of any such claim shall
be subject to the prior written approval of Landlord, which approval shall not
be unreasonably withheld. If an Event of Default exists, Tenant shall not be
entitled to adjust, collect or compromise any such claim or to participate with
Landlord in any adjustment, collection and compromise of the Net Award payable
in connection with a Casualty. Tenant agrees to sign, upon the request of
Landlord, all such proofs of loss, receipts, vouchers and releases. Each insurer
is hereby authorized and directed to make payment under said policies directly
to Landlord or, if required by the Mortgage, to Lender instead of to Landlord
and Tenant jointly, and Tenant hereby appoints each of Landlord and Lender as
Tenant's attorneys-in-fact to endorse any draft therefor. The rights of Landlord
under this Paragraph 17(a) shall be extended to Lender if and to the extent that
any Mortgage so provides.

               (b)   Tenant, immediately upon receiving a Condemnation Notice,
shall notify Landlord and Lender thereof and will promptly deliver to Landlord
and Lender copies of any and all served papers it receives in connection
therewith. So long as no Event of Default exists, Tenant is authorized to
collect, settle and compromise the amount of any Net Award and Landlord shall
have the right to join with Tenant therein. If an Event of Default exists,
Landlord shall be authorized to collect, settle and compromise the amount of any
Net Award and Tenant shall not be entitled to participate with Landlord in any
Condemnation proceeding or negotiations under threat thereof or to contest the
Condemnation or the amount of the Net Award therefor. No agreement with any
condemnor in settlement or under threat of any Condemnation shall be made by
Tenant without the written consent of Landlord, which consent shall not be
unreasonably withheld. Subject to the provisions of this Paragraph 17(b), Tenant
hereby irrevocably assigns to Landlord any award or payment to which Tenant is
or may be entitled by reason of any Condemnation, whether the same shall be paid
or payable for Tenant's leasehold interest hereunder or otherwise; but nothing
in this Lease shall impair Tenant's right to any award or payment on account of
Tenant's trade fixtures, equipment or other tangible property which is not part
of the Equipment, moving expenses or loss of business, if available, to the
extent that and so long as (i) Tenant shall have the right to make, and does
make, a separate claim therefor against the condemnor and (ii) such claim does
not in any way reduce either the amount of the award otherwise payable to
Landlord for the Condemnation of Landlord's fee interest in the Leased Premises
or the amount of the award (if any) otherwise payable for the Condemnation of
Tenant's leasehold interest hereunder. The rights of Landlord under this
Paragraph 17(b) shall also be extended to Lender if and to the extent that any
Mortgage so provides.

               (c)   If any Casualty (whether or not insured against) or Partial
Condemnation shall occur, this Lease shall continue, notwithstanding such event,
and there shall be no abatement or reduction of any Monetary Obligations, except
as provided in Paragraph 17(d). Promptly after such Casualty or Partial
Condemnation, Tenant, as required in Paragraphs 12(a) and 13(b), shall commence
and diligently continue to restore the Leased Premises as nearly as possible to
their value, condition and character immediately prior to such event and will
promptly deliver to Landlord and Lender copies of any and all served papers it
receives in connection therewith (assuming the Leased Premises to have been in
the condition required by this Lease). So long as no Event of Default exists,
upon completion the Leased Premises will be in compliance with all Legal
Requirements and Environmental Laws and access to the Leased Premises will not
be materially impaired on a permanent basis, any Net Award up to and including
$1,000,000 shall be paid by Landlord to Tenant and shall be held in a segregated
account, and Tenant shall restore the Leased Premises in accordance with the
requirements of Paragraphs 12(a) and 13(b) of this Lease. Any Net Award in
excess of $1,000,000 shall be made available by Landlord (or Lender, if required
by the terms of any Mortgage) to Tenant for the restoration of any of the Leased
Premises pursuant to and in accordance with the provisions of 

                                       21
<PAGE>
 
Paragraph 19 hereof. If any Condemnation which is not a Partial Condemnation
shall occur, Tenant shall comply with the terms and conditions of Paragraph 18.
Landlord and Tenant waive the provisions of California Civil Code Sections 1932
and 1933 and California Code of Civil Procedure Section 1265.130.

               (d)   In the event of a Requisition of any of the Leased
Premises, if any Net Award payable by reason of such Requisition or Partial
Condemnation is (i) retained by Landlord (and not applied to restoration in the
case of a Partial Condemnation), each installment of Basic Rent payable on or
after the date on which the Net Award is paid to Landlord shall be reduced by a
fraction, the denominator of which shall be the total amount of all Basic Rent
due from such date to and including the last Basic Rent Payment Date for the
then existing Term and the numerator of which shall be the amount of such Net
Award retained by Landlord, or (ii) paid to Lender, then each installment of
Basic Rent thereafter payable shall be reduced in the same amount and for the
same period as payments are reduced under the Note until such Net Award has been
applied in full or until the Term has expired, whichever first occurs.

         18.   Termination Events.
               ------------------ 

               (a)   If (i) the entire Leased Premises shall be taken by a
Taking or (ii) any substantial portion of the Leased Premises shall be taken by
a Taking and in the prudent business judgment of Tenant cannot be restored to an
integrated unit sufficient for Tenant's business (each of the events described
in the above clauses (i) and (ii) shall hereinafter be referred to as a
"Termination Event"), then (x) in the case of (i) above, Tenant shall be
 -----------------                                             
obligated, within thirty (30) days after Tenant receives a Condemnation Notice
and (y) in the case of (ii) above, Tenant shall have the option, within thirty
(30) days after Tenant receives a Condemnation Notice, to give to Landlord
written notice of the Tenant's election to terminate this Lease (a "Termination
                                                                    -----------
Notice") in the form described in Paragraph 18(b).
------

               (b)   A Termination Notice shall contain (i) notice of Tenant's
intention to terminate this Lease on the first Basic Rent Payment Date which
occurs at least sixty (60) days after receipt of the Termination Notice (the
"Termination Date") and (ii) a binding and irrevocable offer of Tenant to
 ----------------                                                       
pay to Landlord the Termination Amount.

               (c)   If Landlord shall reject such offer to pay the Termination
Amount pursuant to Paragraph 18(b) above by written notice to Tenant (a
"Rejection"), which Rejection shall contain the written consent of Lender, not
 ---------         
later than thirty (30) days following the receipt of the Termination Notice,
then this Lease shall terminate on the Termination Date; provided that, if
Tenant has not satisfied all Monetary Obligations on the Termination Date, then
Landlord may, at its option, extend the date on which this Lease may terminate
to a date which is no later than the first Basic Rent Payment Date after the
Termination Date on which Tenant has satisfied all Monetary Obligations. Upon
such termination (i) all obligations of Tenant hereunder shall terminate except
for any Surviving Obligations, (ii) Tenant shall immediately vacate and shall
have no further right, title or interest in or to any of the Leased Premises and
(iii) the Net Award shall be retained by Landlord. Notwithstanding anything to
the contrary hereinabove contained, if Tenant shall have received a Rejection
and, on the date when this Lease would otherwise terminate as provided above,
Landlord shall not have received the full amount of the Net Award payable by
reason of the applicable Termination Event, then the date on which this Lease is
to terminate automatically shall be extended to the first Basic Rent Payment
Date after the receipt by Landlord of the full amount of the Net Award (but in
no event shall any such extension exceed a maximum of three months) provided
that, if Tenant has not satisfied all Monetary Obligations on such date, then
Landlord may, at its option, extend the date on which this Lease may terminate
to a date which is no later than the first Basic Rent Payment Date after such
date on which Tenant has satisfied all such Monetary Obligations.

                                       22
<PAGE>
 
               (d)   Unless Tenant shall have received a Rejection not later
than the thirtieth (30th) day following receipt of the Termination Notice,
Landlord shall be conclusively presumed to have accepted such offer. If such
offer is accepted by Landlord then, on the Termination Date, Tenant shall pay to
Landlord the Termination Amount and all remaining obligations (including
Monetary Obligations) and, if requested by Tenant, Landlord shall pay to or
assign to Tenant Landlord's entire interest in and to the Net Award.

         19.   Restoration.
               ----------- 

               (a)   Landlord (or Lender if required by any Mortgage) shall hold
Net Award in excess of $1,000,000 in a fund (the "Restoration Fund") and
                                                  ----------------   
disburse amounts from the Restoration Fund only in accordance with the following
conditions and, if the Restoration Fund is held by a Lender, it shall be held
and administered in accordance with Lender's customary procedures for similar
accounts:

                     (i)     prior to commencement of restoration, (A) the
architects, contracts, contractors, budget (which shall include Lender's
administration costs if Lender holds the Restoration Fund), plans and
specifications for the restoration shall have been approved by Landlord and
Lender which approval shall not be unreasonably withheld and (B) Landlord and
Lender shall be provided with performance and payment bonds which insure
satisfactory completion of and payment for the restoration, are in an amount and
form and have a surety reasonably acceptable to Landlord, and name Landlord and
Lender as additional dual obligees;

                     (ii)    at the time of any disbursement, no Event of
Default shall exist, Tenant shall otherwise comply with the requirements imposed
by Lender for disbursement of the Net Award and no mechanics' or materialmen's
liens shall have been filed against any of the Leased Premises and remain
uncontested or undischarged;

                     (iii)   disbursements shall be made from time to time in an
amount not exceeding the cost of the work completed since the last disbursement,
upon receipt of (A) satisfactory evidence, including architects' certificates,
of the stage of completion, the estimated total cost of completion and
performance of the work to date in a good and workmanlike manner in accordance
with the contracts, plans and specifications, (B) waivers of liens, (C)
contractors' and subcontractors' sworn statements as to completed work and the
cost thereof for which payment is requested, (D) a satisfactory bringdown of
title insurance and (E) other evidence of cost and payment so that Landlord can
verify that the amounts disbursed from time to time are represented by work that
is completed, in place and free and clear of mechanics' and materialmen's lien
claims, notices of pendency, stop orders or notices of intention to file same
which have not either been fully bonded and discharged of record or in the
alternative fully insured to the satisfaction of Landlord and Lender by the
title company insuring the Mortgage;

                     (iv)    each request for disbursement shall be accompanied
by a certificate of Tenant, signed by an officer of Tenant, describing the work
for which payment is requested, stating the cost incurred in connection
therewith, stating that Tenant has not previously received payment for such work
and, upon completion of the work, also stating that the work has been fully
completed and complies with the applicable requirements of this Lease;

                     (v)     Landlord may retain ten percent (10%) of the
restoration fund until the restoration is fully completed;

                     (vi)    if the Restoration Fund is held by Landlord, the

<PAGE>
 
                     (vii)   such other reasonable conditions as Landlord or
Lender may impose. 

               (b)   Prior to commencement of restoration and at any time during
restoration, if the estimated cost of completing the restoration work free and
clear of all liens, as reasonably determined by Landlord, exceeds the amount of
the Net Award available for such restoration, the amount of such excess shall,
upon demand by Landlord, be paid by Tenant to Landlord to be added to the
Restoration Fund. Any sum so added by Tenant which remains in the Restoration
Fund upon completion of restoration shall be refunded to Tenant. For purposes of
determining the source of funds with respect to the disposition of funds
remaining after the completion of restoration, the Net Award shall be deemed to
be disbursed prior to any amount added by Tenant.

               (c)   If any sum remains in the Restoration Fund after completion
of the restoration and any refund to Tenant pursuant to Paragraph 19(b), such
sum shall be retained by Landlord or, if required by a Note or Mortgage, paid by
Landlord to a Lender.

               Financing.
               ---------                

               (a)   (i)     Tenant shall have the right, upon thirty (30) days
prior written notice to Landlord and Lender, with no consent of Landlord or
Lender being required or necessary ("Preapproved Assignment") to assign this
                                     ----------------------   
Lease, by operation of law or otherwise, to any Person ("Preapproved Assignee")
                                                         --------------------
(A) that is a wholly-owned United States subsidiary of Tenant on the date of the
assignment (except that an assignment to Vantis Corp. shall not be permitted) or
(B) that immediately following such assignment will have a publicly traded
unsecured senior debt rating of "Baa3" or better from Moody's or a rating of
"BBB-" or better from S&P, provided that the rating from the other agency (i.e.
Moody's or S&P, as the case may be) shall not be less than Ba1 or BB+ and in the
event all of such rating agencies cease to furnish such ratings, then a
comparable rating by any rating agency reasonably acceptable to Landlord and
Lender or (C) that is the surviving entity after a merger or consolidation in
which Tenant is a party, so long as the net worth of such surviving entity is
not less than the net worth of Tenant immediately prior thereto.

                     (ii)    If Tenant desires to assign this Lease, whether by
operation of law or otherwise, to a Person ("Non-Preapproved Assignee") who
                                             ------------------------  
would not be a Preapproved Assignee ("Non-Preapproved Assignment") then Tenant
                                      --------------------------   
shall, not less than forty-five (45) days prior to the date on which it desires
to make a Non-Preapproved Assignment submit to Landlord and Lender information
regarding the following with respect to the Non-Preapproved Assignee
(collectively, the "Review Criteria"): (A) credit, (B) capital structure, (C)
                    ---------------
management, (D) operating history, (E) proposed use of the Leased Premises and
(F) risk factors associated with the proposed use of the Leased Premises by the

concerns, product liability and the like. Landlord and Lender shall review such
information and shall approve or disapprove the Non-Preapproved Assignee no
later than the thirtieth (30th) day following receipt of all such information,
and Landlord and Lender shall be deemed to have acted reasonably in granting or
withholding consent if such grant or disapproval is based on their review of the
Review Criteria applying prudent business judgment.

               (b)   Tenant shall have the right, upon thirty (30) days prior
written notice to Landlord and Lender, to enter into one or more subleases that
demise, in the aggregate, up to but not in excess of thirty percent (30%) of the

thirty percent (30%) of the gross space in the Leased Premises without the prior
written consent of Landlord, which consent shall be granted or withheld based on
a review of the Review Criteria as they relate to the proposed sublessee and the
terms of the proposed sublease. Landlord and Lender shall be deemed to have
acted reasonably in granting or withholding consent if such grant or disapproval
is based on their review of the Review Criteria applying prudent business
judgment.

               (c)   If Tenant assigns all its rights and interest under this
Lease, the assignee under such assignment shall expressly assume all the
obligations of Tenant hereunder, actual or contingent, including obligations of
Tenant which may have arisen on or prior to the date of such assignment, by a
written instrument delivered to Landlord at the time of such assignment. Each
sublease of any of the Leased Premises shall be subject and subordinate to the
provisions of this Lease. No assignment or sublease made as permitted by this
Paragraph 21 shall affect or reduce any of the obligations of Tenant hereunder,
and all such obligations shall continue in full force and effect as obligations
of a principal and not as obligations of a guarantor, as if no assignment or
sublease had been made. No assignment or sublease shall impose any additional
obligations on Landlord under this Lease.

               (d)   Tenant shall, within ten (10) days after the execution and
delivery of any assignment or sublease deliver a duplicate original copy thereof
to Landlord which, in the event of an assignment, shall be in recordable form.

               (e)   As security for performance of its obligations under this
Lease, Tenant hereby grants, conveys and assigns to Landlord all right, title
and interest of Tenant in and to all subleases now in existence or hereafter
entered into for any or all of the Leased Premises, any and all extensions,
modifications and renewals thereof and all rents, issues and profits therefrom.
Landlord hereby grants to Tenant a license to collect and enjoy all rents and
other sums of money payable under any sublease of any of the Leased Premises,
provided, however, that Landlord shall have the absolute right to revoke said
license and to collect such rents and sums of money, to retain the same and to
the extent received the same shall be credited against Basic Rent as the same
shall be due and owing.

               (f)   Tenant shall not have the power to mortgage, pledge or
otherwise encumber its interest under this Lease or any sublease of the Leased
Premises, and any such mortgage, pledge or encumbrance made in violation of this
Paragraph 21 shall be void and of no force and effect.

               (g)   Tenant shall transfer its interest in this Lease to any
Person who purchases all or substantially all of the assets of Tenant.

               (h)   Landlord may sell or transfer the Leased Premises at any
time without Tenant's consent to any third party (each a "Third Party
                                                          -----------

---------   
in no event may Landlord sell or transfer to Intel Corporation, National
Semiconductor, Inc. or to any Person directly engaged in the design, engineering
or manufacturing of integrated circuits, including, without limitation, micro-
processors, memory, networking, logic and communications devices (any of the
foregoing a "Prohibited Purchaser"). The foregoing conditions shall not apply to
             --------------------                  
any sale of the Leased Premises that occurs during the last eighteen months of
the Term, or to any sale to a pension fund or finance affiliate of a Prohibited
Purchaser (excluding, however, a pension fund or finance affiliate of Intel
Corporation or National Semiconductor, Inc.), and, in any event, the aforesaid
conditions shall be null and void and of no force and effect upon any
foreclosure of a Loan or acceptance by a Lender of a deed in lieu thereof. In
the event of any such transfer, Tenant shall attorn to any Third Party Purchaser
as Landlord so long as such Third Party Purchaser and Landlord notify Tenant in
writing of such transfer and such Third Party Purchaser expressly 

                                       25
<PAGE>
 
assumes in writing the obligations of the Landlord hereunder. At the request of
Landlord and at Landlord's cost, Tenant will execute such documents confirming
the agreement referred to above and such other agreements as Landlord may
reasonably request, provided that such agreements do not increase the
liabilities and obligations of Tenant hereunder. Tenant shall not bear any costs
or expenses in connection with any sale or transfer of the Leased Premises to a
Third Party Purchaser. In no event shall the terms of this Paragraph 21(g) be or
be deemed to be in effect following the termination or expiration of this Lease.

         22.   Events of Default.
               ----------------- 

               (a)   The occurrence of any one or more of the following (after
expiration of any applicable cure period as provided in Paragraph 22(b)) shall,
at the sole option of Landlord, constitute an "Event of Default" under this
                                               ----------------

Monetary Obligation, regardless of the reason for such failure;

a violation or breach of, any other provision of this Lease not otherwise
specifically mentioned in this Paragraph 22(a);

                     (iii)   any representation or warranty made by Tenant
herein or in any certificate, demand or request made pursuant hereto proves to
be incorrect, when made, in any material respect;

maturity by Tenant in any payment of principal or interest on any obligations
for borrowed money having an original principal balance of $10,000,000 or more
in the aggregate, or in the performance of any other provision contained in any
instrument under which any such obligation is created or secured (including the
breach of any covenant thereunder), (x) if such payment is a payment at maturity
or a final payment, or (y) if an effect of such default is to cause, or permit
any Person to cause, such obligation to become due prior to its stated maturity
and Tenant is not diligently and in good faith contesting such default or has
paid such obligation in full;

                     (v)     a default by Tenant beyond any applicable cure
period in the payment of rent under, or in the performance of any other material
provision of, any other lease or leases that have, in the aggregate, rental
obligations over the terms thereof of $10,000,000 or more if the Landlord under
any such lease or leases actually terminates such lease;

                     (vi)    a final, non-appealable judgment or judgments for

judgment) cause any material adverse harm to Landlord or any of the Leased
Premises, the cure period shall be extended for the period required to cure the
default (but such cure period, including any extension, shall not in the
aggregate exceed ninety (90) days), provided that Tenant shall commence to cure
the default within the said twenty-day period and shall actively, diligently and
in good faith proceed with and continue the curing of the default until it shall
be fully cured. The notices described in this Paragraph 22(b) are in lieu and
not in addition to the notice under California Civil Code 1161.

         23.   Remedies and Damages Upon Default.
               ----------------------------------

               (a)  If an Event of Default shall have occurred and is
continuing, Landlord shall have the right, at its sole option, then or at any
time thereafter, to exercise its remedies and to collect damages from Tenant in
accordance with this Paragraph 23, subject in all events to applicable Law,
without demand upon or notice to Tenant except as otherwise provided in
Paragraph 22(b) and this Paragraph 23.

                     (i)     Landlord may give Tenant notice of Landlord's
intention to terminate this Lease on a date specified in such notice. Upon such
date, this Lease, the estate 

                                       27

hereby granted and all rights of Tenant hereunder shall expire and terminate.
Upon such termination, Tenant shall immediately surrender and deliver possession
of the Leased Premises to Landlord in accordance with Paragraph 26. If Tenant
does not so surrender and deliver possession of the Leased Premises, Landlord
may re-enter and repossess the Leased Premises or by summary proceedings,
ejectment or any other lawful means or procedure. Upon or at any time after
taking possession of the Leased Premises, Landlord may, by peaceable means or
legal process, remove any Persons or property therefrom. Landlord shall be under
no liability for or by reason of any such entry, repossession or removal.
Notwithstanding such entry or repossession, Landlord may (A) exercise the remedy
set forth in and collect the damages permitted by Paragraph 23(a)(iii) or (B)
collect the damages set forth in Paragraph 23(b) or (c).

                     (ii)    After repossession of the Leased Premises pursuant
to clause (i) above, Landlord shall have the right to relet any of the Leased
Premises to such tenant or tenants, for such term or terms, for such rent, on
such conditions and for such uses as Landlord in its sole discretion may
determine, and collect and receive any rents payable by reason of such
reletting. Landlord may pay such leasing commissions, retain such management and
make such Alterations in connection with such reletting as it may deem advisable
in its sole discretion. Notwithstanding any such reletting, Landlord may collect
the damages set forth in Paragraph 23(c).

                     (iii)   Landlord may declare by notice to Tenant the entire
Basic Rent (in the amount of Basic Rent then in effect) for the remainder of the
then current Term to be immediately due and payable. Tenant shall immediately
pay to Landlord all such Basic Rent discounted to its present value, using a
discount factor of eight percent (8%) per annum, all accrued Rent then due and
unpaid, all other Monetary Obligations which are then due and unpaid and all
Monetary Obligations which arise or become due by reason of such Event of
Default (including any Costs of Landlord). Upon receipt by Landlord of all such
accelerated Basic Rent and Monetary Obligations, this Lease shall remain in full
force and effect and Tenant shall have the right to possession of the Leased
Premises from the date of such receipt by Landlord to the end of the Term, and
subject to all the provisions of this Lease, including the obligation to pay all
increases in Basic Rent and all Monetary Obligations that subsequently become
due, except that (A) no Basic Rent which has been prepaid hereunder sh
