within which to pay any rent or prevent Landlord from exercising any right or
remedy available to Landlord upon Tenant's failure to pay any rent due under
this Lease in a timely fashion, including any right to terminate this Lease
pursuant to Paragraph 13.2B. If any rent remains delinquent for a period in
excess of 30 days then, in addition to such late charge, Tenant shall pay to
Landlord interest on any rent that is not paid when due at the Agreed Interest
Rate following the date such amount became due until paid.

     3.5  SECURITY DEPOSIT:  On the Effective Date, Tenant shall deposit with
Landlord the amount set forth in Section M of the Summary as security for the
performance by Tenant of its obligations under this Lease, and not as prepayment
of rent (the "Security Deposit").  Landlord may from time to time apply such
portion of the Security Deposit as is reasonably necessary for the following
purposes: (i) to remedy any default by Tenant in the payment of rent; (ii) to
repair damage to the Premises caused by Tenant; (iii) to clean the Premises upon
termination of the Lease; and (iv) to remedy any other default of Tenant to the
extent permitted by Law and, in this regard, Tenant hereby waives any
restriction on the uses to which the Security Deposit may be put contained in
California Civil Code Section 1950.7. In the event the Security Deposit or any
portion thereof is so used, Tenant agrees to pay to Landlord promptly upon
demand an amount in cash sufficient to restore the Security Deposit to the full
original amount.  Landlord shall not be deemed a trustee of the Security
Deposit, may use the Security Deposit in business, and shall not be required to
segregate it from its general accounts.  Tenant shall not be entitled to any
interest on the Security Deposit.  If Landlord transfers the Premises during the
Lease Term, Landlord shall pay the Security Deposit to any transferee of
Landlord's interest in conformity with the provisions of California Civil Code
Section 1950.7 and/or any successor statute, in which event the transferring
Landlord will be released from all liability for the return of the Security
Deposit.

any of the following kinds of capital improvements to the Project and the cost
thereof is not reimbursable as a Common Operating Expense: (i) capital
improvements required to be constructed in order to comply with any Law
(excluding any Hazardous Materials Law) not in effect or applicable to the
Project as of the Effective Date; (ii) modification of existing or construction
of additional capital improvements or building service equipment for the purpose
of reducing the consumption of utility services or Common Operating Expenses of
the Project (but not in excess of the savings realized as a consequence of the
capital improvement); (iii) replacement of capital improvements or building
service equipment existing as of the Effective Date when required because of
normal wear and tear; and (iv) restoration of any part of the Project that has
been damaged by any peril to the extent the cost thereof is not covered by
insurance proceeds actually recovered by Landlord up to a maximum amount per
occurrence of 10% of the then replacement cost of the Premises.  The amount of
Additional Rent Tenant is to pay with respect to each such capital improvement
shall be determined as follows:

          A.   All costs reasonably paid by Landlord to construct such
improvements (including financing costs) shall be amortized over the useful life
of such improvement (as reasonably determined by Landlord in accordance with
generally accepted accounting principles) with interest on the unamortized
balance at the then prevailing market rate Landlord would pay if it borrowed
funds to construct such improvements from an institutional lender, and Landlord
shall inform Tenant of the monthly amortization payment required to so amortize
such costs, and shall also provide Tenant with the information upon which such
determination is made.

          B.   As Additional Rent, Tenant shall pay at the same time the Base
Monthly Rent is due an amount equal to Tenant's Share of that portion of
such monthly amortization payment fairly allocable to the Buildings (as
reasonably determined by Landlord) for each month after such improvements are

it may be extended), or (ii) the end of the term over which such costs were
amortized.

liens and shall pay when due all bills arising out of any work performed,
materials furnished, or obligations incurred by Tenant or Tenant's Agents
relating to the Project.  If any claim of lien is recorded (except those
caused by Landlord or Landlord's Agents), Tenant shall bond against or
discharge the same within 10 days after the same has been recorded against
the Project.  Should any lien be filed against the Project or any action be
commenced affecting title to the Project, the party receiving notice of such
lien or action shall immediately give the other party written notice thereof.

     5.6  TAXES ON TENANT'S PROPERTY: Tenant shall

charges levied, assessed or imposed against Tenant or Tenant's estate in this
Lease or the property of Tenant situated within the Premises which become due
during the Lease Term.  If any tax or other charge is assessed by any
governmental agency because of the execution of this Lease, such tax shall be
paid by Tenant.  On demand by Landlord, Tenant shall furnish Landlord with
satisfactory evidence of these payments.

and repair of any such facilities which serve only the Premises, including all
such facilities that are within the walls or floor, or on the roof of the
Premises, and any part of such facility that is not within the Premises, but

shall replace any damaged or broken glass in the Premises (including all
interior and exterior doors and windows) with glass of the same kind, size and

approved by Landlord, which contract provides for the periodic washing of all
such windows at least once every 60 days during the Lease Term.  Tenant shall

Landlord, shall restrain such unauthorized use by appropriate proceedings.  In
exercising any such rights regarding the Common Area, (i) Landlord shall make a
reasonable effort to minimize any disruption to Tenant's business, and (ii)
Landlord shall not exercise its rights to control the Common Area in a manner

Materials Laws.  Tenant shall indemnify, defend upon demand with counsel
reasonably acceptable to Landlord, and hold harmless Landlord from and against
any liabilities, losses, claims, damages, lost profits, consequential damages,
interest, penalties, fines, monetary sanctions, attorneys' fees, experts' fees,
court costs, redemption costs, investigation costs, and other expenses which
result from or arise in any manner whatsoever out of the use, storage,
treatment, transportation, release, or disposal of Hazardous Materials on or
about the Project by Tenant or Tenant's Agents after the Effective Date.

          B.   If the presence of Hazardous Materials on the Project caused or
permitted by Tenant or Tenant's Agents after the Effective Date results in
contamination or deterioration of water or soil resulting in a level of
contamination greater than the levels established as acceptable by any
governmental agency having jurisdiction over such contamination, then Tenant
shall promptly take any and all action necessary to investigate and remediate
such contamination if required by Law or as a condition to the issuance or
continuing effectiveness of any governmental approval which relates to the use
of the Project or any part thereof.  Tenant shall further be solely responsible
for, and shall defend, indemnify and hold Landlord and its agents harmless from
and against, all claims, costs and liabilities, including attorneys fees and

Landlord receives notice prior to such Hazardous Materials being brought onto
the Premises and which Landlord consents in writing may be brought onto the
Premises.  At any time during the Lease Term, Tenant shall, within five days
after written request therefor received from Landlord, disclose in writing all
Hazardous Materials that are being used by Tenant on the Project, the nature of
such use, and the manner of storage and disposal.

          D.   Landlord may cause testing wells to be installed on the Project,
and may cause the ground water to be tested to detect the presence of Hazardous
Material by the use of such tests as are then customarily used for such
purposes. If Tenant so requests, Landlord shall supply Tenant with copies of
such test results. The cost of such tests and of the installation, maintenance,
repair and replacement of such wells shall be paid by Tenant if such tests
disclose the existence of facts which gives rise to liability of Tenant pursuant
to its indemnity given in Paragraph 7.2A and/or Paragraph 7.2B.

          E.   As used herein, the term "Hazardous Material," means any
hazardous or toxic substance, material or waste which is or becomes regulated by
any local  governmental authority, the State of California or the United
States Government. The term "Hazardous Material," includes, without limitation,
petroleum products, asbestos, PCBs, and any material or substance which is (i)
listed under Article 9 or defined as hazardous or extremely hazardous pursuant
to Article 11 of Title 22 of the California Administrative Code, Division 4,
Chapter 20, (ii) defined as a "hazardous waste" pursuant to Section 1004 of the
Federal Resource Conservation and Recovery Act, 42 U.S.C. 6901 et seq. (42
U.S.C. 6903), or (iii) defined as a "hazardous substance" pursuant to Section
101 of the Comprehensive Environmental Response, Compensation and Liability
Act, 42 U.S.C. 9601 et seq. (42 U.S.C. 9601).  As used herein, the term
"Hazardous Material Law" shall mean any statute, law, ordinance, or regulation
of any governmental body or agency (including the U.S. Environmental Protection
Agency, the California Regional Water Quality Control Board, and the California
Department of Health Services) which regulates the use, storage, release or
disposal of any Hazardous Material.

          F.   The obligations of Landlord and Tenant under this Paragraph 7.2
shall survive the expiration or earlier termination of the Lease Term.  The
rights and obligations of Landlord and Tenant with respect to issues relating to
Hazardous Materials are exclusively established by this Paragraph 7.2 and
Paragraph 22 of the First Addendum to Lease.  In the event of any inconsistency
between any other part of this Lease and this Paragraph 7.2, the terms of this
Paragraph 7.2 shall control.

     7.3  UTILITIES:  Tenant shall promptly pay, as the same become due, all
charges for water, gas, electricity, telephone, sewer service, waste pick-up and
any other utilities, materials or services furnished directly to or used by
Tenant on or about the Premises during the Lease Term, including, without
limitation, (i) meter, use and/or connection fees, hook-up fees, or standby fee
(excluding any connection fees or hook-up fees which relate to making the
existing electrical, gas, and water service available to the Premises as of the
Commencement Date), and (ii) penalties for discontinued or interrupted service.
If any utility service is not separately metered to the Premises, then Tenant
shall pay its pro rata share of the cost of such utility service with all others
served by the service not separately metered.  However, if Landlord determines
that Tenant is using a disproportionate amount of any utility service not
separately metered, then Landlord at its election may (i) periodically charge
Tenant, as Additional Rent, a sum equal to Landlord's reasonable estimate of the
cost of Tenant's excess use of such utility service, or (ii) install a separate
meter (at Tenant's expense) to measure the utility service supplied to the
Premises.

     7.4  COMPLIANCE WITH GOVERNMENTAL REGULATIONS:  Landlord and Tenant shall
comply with all rules, regulations and requirements promulgated by national,
state or local governmental agencies or utility suppliers concerning the use of
utility services, including any rationing, limitation or other control.  Except
as expressly provided to the contrary in this Lease, Tenant shall not be
entitled to terminate this Lease nor to any abatement in rent by reason of such
compliance.

Operating Expenses; provided, however, if the Project contains more than one
building, then Tenant shall pay Tenant's Share of all Common Operating
Expenses fairly allocable to the Buildings including (i) all Common Operating
Expenses paid with respect to the maintenance, repair, replacement and use of
the Building, and (ii) a proportionate share (based on the Building Gross
Leasable Area as a percentage of the Project Gross Leasable Area) of all
Common Operating Expenses which relate to the Project in general are not
fairly allocable to any one building that is part of the Project.  Tenant
shall pay such share of the actual Common Operating Expenses incurred or paid
by Landlord but not theretofore billed to Tenant within 10 days after receipt
of a written bill therefor from Landlord, on such periodic basis as Landlord
shall designate, but in no event more frequently than once a month.
Alternatively, Landlord may from time to time require that Tenant pay
Tenant's Share of Common Operating Expenses in advance in estimated monthly
installments, in accordance with the following: (i) Landlord shall deliver to
Tenant Landlord's reasonable estimate of the Common Operating expenses it
anticipates will be paid or incurred for the Landlord's fiscal year in
question; (ii) during such Landlord's fiscal year Tenant shall pay such share
of the estimated Common Operating Expenses in advance in monthly installments
as required by Landlord due with the installments of Base Monthly Rent; and
(iii) within 90 days after the end of each Landlord's fiscal year, Landlord
shall furnish to Tenant a statement in reasonable detail of the actual Common
Operating Expenses paid or incurred by Landlord during the just ended
Landlord's fiscal year and thereupon there shall be an adjustment between
Landlord and Tenant, with payment to Landlord or credit by Landlord against
the next installment of Base Monthly Rent, as the case may require, within 10
days after delivery Landlord to Tenant of said statement (or if the Lease has
terminated by a cash payment delivered concurrently with the reconciliation),
so that Landlord shall receive the entire amount of Tenant's Share of all
Common Operating Expenses for such Landlord's fiscal year and no more.
Tenant shall have the right at its expense, exercisable upon reasonable prior
written notice to Landlord, to inspect at Landlord's office during normal
business hours Landlord's books and records as they relate to Common
Operating Expenses.  Such inspection must be within 90 days of Tenant's
receipt of Landlord's annual statement for the same, and shall be limited to
verification of the charges contained in such statement.  Tenant may not
withhold payment of such bill pending completion of such inspection, but, if an
error of more than 10% of the annual amount of Common Operating Expenses is
made, Landlord shall pay the reasonable costs of the audit and make
reimbursement of the overpayment within 30 days of Tenant's demand.

     8.2  COMMON OPERATING EXPENSES DEFINED:  The term "Common Operating
Expenses" shall mean the following:

               A.   All costs and expenses paid or incurred by Landlord in doing
the following (including payments to independent contractors providing services
related to the performance of the following): (i) maintaining, cleaning,
repairing and resurfacing the roof (including repair of leaks) and the exterior

maintenance of the liability, fire and property damage insurance covering the
Project carried by Landlord pursuant to Paragraph 9.2 (including the prepayment
of premiums for coverage of up to one year); (iii) maintaining, repairing,
operating and replacing when necessary HVAC equipment, utility facilities and
other building service equipment; (iv) providing utilities to the Common Area
(including lighting, trash removal and water for landscaping irrigation); (v)

maintaining, repairing, cleaning, painting, restriping and resurfacing the
Common Area; (vii) replacement or installation of lighting fixtures, directional

providing security;

               B.   The following costs: (i) Real Property Taxes as defined in
Paragraph 8.3; (ii) the amount of any "deductible" paid by Landlord with respect
to damage caused by any Insured Peril; (iii) the cost to repair damage caused by
an Uninsured Peril up to

                                          8

<PAGE>
                                       LEASE

a maximum amount in any 12 month period equal to 2% of the replacement cost of
the buildings or other improvements damaged; and (iv) that portion of all
compensation (including benefits and premiums for workers' compensation and
other insurance) paid to or on behalf of employees of Landlord but only to the
extent they are involved in the performance of the work described by Paragraph
8.2A that is fairly allocable to the Project;

          C.   Fees for management services rendered by either Landlord or a
third party manager engaged by Landlord (which may be a party affiliated with
Landlord), except that the total amount charged for management services and
included in Tenant Share of Common Operating Expenses shall not exceed the
monthly rate of 5% of the Base Monthly Rent.

          D.   All additional costs and expenses incurred by Landlord with
respect to the operation, protection, maintenance, repair and replacement of
the Project which would be considered a current expense (and not a capital
expenditure) pursuant to generally accepted accounting principles; provided,
however, that Common Operating Expenses shall not include any of the
following: (i) payments on any loans or ground leases affecting the Project;
(ii) depreciation of any buildings or any major systems of building service
equipment within the Project; (iii) leasing commissions; (iv) the cost of
tenant improvements installed for the exclusive use of other tenants of the
Project; (v) any cost incurred in complying with Hazardous Materials Laws,
which subject is governed exclusively by Paragraph 7.2 and (vi) reserves for
expenditures beyond the calendar year in question.

     8.3  REAL PROPERTY TAXES DEFINED:  The term "Real Property Taxes" shall
mean all taxes, assessments, levies, and other charges of any kind or nature
whatsoever, general and special, foreseen and unforeseen (including all
installments of principal and interest required to pay any existing or future
general or special assessments for public improvements, services or benefits,
and any increases resulting from reassessments resulting from a change in
ownership, new construction, or any other cause), now or hereafter imposed by
any governmental or quasi-governmental authority or special district having the
direct or indirect power to tax or levy assessments, which are levied or
assessed against, or with respect to the value, occupancy or use of a or any
portion of the Project (as now constructed or as may at any time hereafter be
constructed, altered, or otherwise changed) or Landlord's interest therein, the
fixtures, equipment and other property of Landlord, real or personal, that are
an integral part of and located on the Project, the gross receipts, income, or
rentals from the Project, or the use of parking areas, public utilities, or
energy within the Project, or Landlord's business of leasing the Project.  If at
any time during the Lease Term the method of taxation or assessment of the
Project prevailing as of the Effective Date shall be altered so that in lieu of
or in addition to any Real Property Tax described above there shall be levied,
assessed or imposed (whether by reason of a change in the method of taxation or
assessment, creation of a new tax or charge or any other cause) an alternate or
additional tax or charge (i) on the value, use or occupancy of the Project or
Landlord's interest therein, or (ii) on or measured by the gross receipts,
income or rentals from the Project, on Landlord's business of leasing the
Project, or computed in any manner with respect to the operation of the Project,
then any such tax or charge, however designated, shall be included within the
meaning of the term "Real Property Taxes" for purposes of this Lease.  If any
Real Property Tax is based upon property or rents unrelated to the Project, then
only that part of such Real Property Tax that is fairly allocable to the Project
shall be included within the meaning of the term "Real Property Taxes".
Notwithstanding the foregoing, the term "Real Property Taxes" shall not include
estate, inheritance, transfer, gift or franchise taxes of Landlord or the
federal or state net income tax imposed on Landlord's income from all sources.

                                     INSURANCE

     9.1  TENANT'S INSURANCE:  Tenant shall maintain insurance complying with
all of the following:

               A.   Tenant shall procure, pay for and keep in full force and
effect the following:

                         (1)  Commercial general liability insurance, including
property damage, against liability for personal injury, bodily injury, death and
damage to property occurring in or about, or resulting from an occurrence in or
about, the Premises with combined single limit coverage of not less than the
amount of Tenant's Liability Insurance Minimum specified in SECTION P of the
Summary, which insurance shall contain a "contractual liability" endorsement
insuring Tenant's performance of Tenant's obligation to indemnify Landlord
contained in Paragraph 10.3;

                         (2)  Fire and property damage insurance in so-called
"all risk" form insuring Tenant's Trade Fixtures and Tenant's Alterations for at
least 90% the value thereof;

                         (3)  Such other insurance that is either (i) required
by any Lender, or (ii) reasonably required by Landlord and customarily carried
by tenants of similar property in similar businesses.

               B.   Where applicable and required by Landlord, each policy of
insurance required to be carried by Tenant pursuant to this Paragraph 9.1: (i)
shall name Landlord and such other parties in interest as Landlord reasonably
designates as additional insured; (ii) shall be primary insurance which provides
that the insurer shall be liable for the full amount of the loss up to and
including the total amount of liability set forth in the declarations without
the right of contribution from any other insurance coverage of Landlord; (iii)
shall be in a form reasonably satisfactory to Landlord; (iv) shall be carried
with companies reasonably acceptable to Landlord; (v) shall provide that such
policy shall not be subject to cancellation, lapse or change except after at
least 30 days prior written notice to Landlord so long as such provision of 30
days notice is reasonably obtainable, but in any event not less than 10 days
prior written notice; (vi) shall not have a "deductible" in excess of such
amount as is approved by Landlord; (vii) shall contain a cross liability
endorsement; and (viii) shall contain a "severability" clause.  If Tenant has in
full force and effect a

                                         9

<PAGE>

                                       LEASE

blanket policy of liability insurance with the same coverage for the Premises as
described above, as well as other coverage of other premises and properties of
Tenant, or in which Tenant has some interest, such blanket insurance shall
satisfy the requirements of this Paragraph 9.1.

          C.   A copy of each paid-up policy evidencing the insurance required
to be carried by Tenant pursuant to this Paragraph 9.1 (appropriately
authenticated by the insurer) or a certificate of the insurer, certifying that
such policy has been issued, providing the coverage required by this Paragraph
9.1, and containing the provisions specified herein, shall be delivered to
Landlord prior to the time Tenant or any of its Agents enters the Premises and
upon renewal of such policies, but not less than 5 days prior to the expiration
of the term of such coverage.  Landlord may, at any time, and from time to time,
inspect and/or copy any and all insurance policies required to be procured by
Tenant pursuant to this Paragraph 9.1. If any Lender reasonably determines at
any time that the amount of coverage required for any policy of insurance Tenant
is to obtain pursuant to this Paragraph 9.1 is not adequate, then Tenant shall
increase such coverage for such insurance to such amount as such Lender
reasonably deems adequate, not to exceed the level of coverage for such
insurance commonly carried by comparable businesses similarly situated.

     9.2  LANDLORD'S INSURANCE:  Landlord shall have the following
obligations and options regarding insurance:

          A.   Landlord shall maintain a policy or policies of fire and
property damage insurance in so-called "all risk" form insuring Landlord (and
such others as Landlord may designate) against loss of rents for a period of
not less than 12 months and from physical damage to the Project with coverage
of not less than the full replacement cost thereof.  Landlord may so insure
the Project separately, or may insure the Project with other property owned
by Landlord which Landlord elects to insure together under the same policy or
policies. Such fire and property damage insurance (i) may be endorsed to
cover loss caused by such additional perils against which Landlord may elect
to insure, including earthquake and/or flood, and to provide such additional
coverage as Landlord reasonably requires, and (ii) shall contain reasonable
"deductibles" which, in the case of earthquake and flood insurance, may be up
to 15% of the replacement value of the property insured or such higher amount
as is then commercially reasonable.  Landlord shall not be required to cause
such insurance to cover any Trade Fixtures or Tenant's Alterations of Tenant.

          B.   Landlord may maintain a policy or policies of commercial general
liability insurance insuring Landlord (and such others as are designated by
Landlord) against liability for personal injury, bodily injury, death and damage
to property occurring or resulting from an occurrence in, on or about the
Project, with combined single limit coverage in such amount as Landlord from
time to time determines is reasonably necessary for its protection.

     9.3  TENANT'S OBLIGATION TO REIMBURSE: If Landlord's insurance rates for
the Building are increased at any time during the Lease Term as a result of the
nature of Tenant's use of the Premises, Tenant shall reimburse Landlord for the
full amount of such increase immediately upon receipt of a bill from Landlord
therefor.

     9.4  RELEASE AND WAIVER OF SUBROGATION:  Notwithstanding anything to the
contrary in this Lease, parties hereto release each other, and their
respective Agents and employees, from any liability for injury to any person
or damage to property that is caused by or results from any risk insured
against under any valid and collectible insurance policy carried by either of
the parties which contains a waiver of subrogation by the insurer and is in
force at the time of such injury or damage or which is required by this
Article 9 to be insured against (without regard to whether such insurance is
actually in force); subject to the following limitations: (i) the foregoing
provision shall not apply to the commercial general liability insurance
described by subparagraphs Paragraph 9.1A and 9.2B; (iii) Paragraph) such
release shall apply to liability resulting from any risk insured against or
covered by self-insurance maintained or provided by Tenant to satisfy the
requirements of Paragraph 9.1 to the extent permitted by this Lease; and
(iii) Tenant shall not be released from any such liability to the extent any
damages resulting from such injury or damage are not covered by the recovery
obtained by Landlord from such insurance, but only if the insurance in
question permits such partial release in connection with obtaining a waiver
of subrogation from the insurer.  This release shall be in effect only so
long as the applicable insurance policy contains a clause to the effect that
this release shall not affect the right of the insured to recover under such
policy. Each party shall use reasonable efforts to cause each insurance
policy obtained by it to provide that the insurer waives all right of
recovery by way of subrogation against the other party and its Agents and
employees in connection with any injury or damage covered by such policy.
However, if any insurance policy cannot be obtained with such a waiver of
subrogation, or if such waiver of subrogation is only available at additional
cost and the party for whose benefit the waiver is to be obtained does not
pay such additional cost, then the party obtaining such insurance shall
notify the other party of that fact and thereupon shall be relieved of the
obligation to obtain such waiver of subrogation rights from the insurer with
respect to the particular insurance involved.

                  LIMITATION ON LANDLORD'S LIABILITY AND INDEMNITY

     10.1 LIMITATION ON LANDLORD'S LIABILITY: Landlord shall not be liable to
Tenant, nor shall Tenant be entitled to terminate this Lease or to any abatement
of rent (except as expressly provided otherwise herein), for any injury to
Tenant or Tenant's Agents, damage to the property of Tenant or Tenant's Agents,
or loss to Tenant's business resulting from any cause, including without
limitation any: (i) failure, interruption or installation of any HVAC or other
utility system or service; (ii) failure to furnish or delay in furnishing any
utilities or services when such failure or delay is caused by fire or other
peril, the elements, labor disturbances of any character, or any other accidents
or other conditions beyond the reasonable control of


                                         10

<PAGE>

                                       LEASE

Landlord; (iii) limitation, curtailment, rationing or restriction on the use of
water or electricity, gas or any other form of energy or any services or utility
serving the Project; (iv) vandalism or forcible entry by unauthorized persons or
the criminal act of any person; or (v) penetration of water into or onto any
portion of the Premises or the Building through roof leaks or otherwise.
Notwithstanding the foregoing but subject to Paragraph 9.4 Paragraph shall be
liable for any such injury, damage or loss which is proximately caused by
Landlord's willful misconduct or active negligence of which Landlord has actual
notice and a reasonable opportunity to cure but which it fails to so cure.

     10.2 LIMITATION ON TENANT'S RECOURSE:  If Landlord is a corporation,
trust, partnership, joint venture, unincorporated association or other form
of business entity: (i) the obligations of Landlord shall not constitute
personal obligations of the officers, directors, trustees, partners, joint
venturers, members, owners, stockholders, or other principals or
representatives of such business entity; and (ii) Tenant shall not have
recourse to the assets of such officers, directors, trustees, partners, joint
venturers, members, owners, stockholders, principals or representatives
except to the extent of their interest in the Project.  Tenant shall have
recourse only to the interest of Landlord in the Project for the satisfaction
of the obligations of Landlord and shall not have recourse to any other
assets of Landlord for the satisfaction of such obligations.

     10.3 INDEMNIFICATION OF LANDLORD:  Tenant shall hold harmless, indemnify
and defend Landlord, and its employees, agents and contractors, with competent
counsel reasonably satisfactory to Landlord (and Landlord agrees to accept
counsel that any insurer requires be used), from all liability, penalties,
losses, damages, costs, expenses, causes of action, claims and/or judgments
arising by reason of any death, bodily injury, personal injury or property
damage resulting from (i) any cause or causes whatsoever (other than the willful
misconduct or active negligence of Landlord of which Landlord has had notice and
a reasonable time to cure, but which Landlord has failed to cure) occurring in
or about or resulting from an occurrence in or about the Premises during the
Lease Term, (ii) the negligence or willful misconduct of Tenant or its agents,
employees and contractors, wherever the same may occur, or (iii) an Event of
Tenant's Default.  The provisions of this Paragraph 10.3 shall survive the
expiration or sooner termination of this Lease.

                                     ARTICLE 11

                                 DAMAGE TO PREMISES

     11.1 LANDLORD'S DUTY TO RESTORE:  If the Premises are damaged by any peril
after the Effective Date, Landlord shall restore the Premises unless the Lease
is terminated by Landlord pursuant to Paragraph 11.2 or by Tenant pursuant to
Paragraph 11.3. All insurance proceeds available from the fire and property
damage insurance carried by Landlord pursuant to Paragraph 9.2 shall be paid to
and become the property of Landlord.  If this Lease is terminated pursuant to
either Paragraph 11.2 or Paragraph 11.3, then all insurance proceeds available
from insurance carried by Tenant which covers loss to property that is
Landlord's property or would become Landlord's property on termination of this
Lease shall be paid to and become the property of Landlord.  If this Lease is
not so terminated, then upon receipt of the insurance proceeds (if the loss is
covered by insurance) and the issuance of all necessary governmental permits,
Landlord shall commence and diligently prosecute to completion the restoration
of the Premises, to the extent then allowed by Law, to substantially the same
condition in which the Premises were immediately prior to such damage.
Landlord's obligation to restore shall be limited to the Premises and interior
improvements constructed by Landlord as they existed as of the Commencement
Date, excluding any Tenant's Alterations, Trade Fixtures and/or personal
property constructed or installed by Tenant in the Premises.  Tenant shall
forthwith replace or fully repair all Tenant's Alterations installed by Tenant
and existing at the time of such damage or destruction, and all insurance
proceeds received by Tenant from the insurance carried by it pursuant to
Paragraph 9.1A(2) shall be used for such purpose.

     11.2 LANDLORD'S RIGHT TO TERMINATE:  Landlord shall have the right to
terminate this Lease in the event any of the following occurs, which right may
be exercised only by delivery to Tenant of a written notice of election to
terminate within 30 days after the date of such damage:

          A.   Either the Project or the Premises is damaged by an Insured Peril
to such an extent that the estimated cost to restore exceeds 33% of the then
actual replacement cost thereof;

          B.   Either the Project or the Premises is damaged by an Uninsured
Peril to such an extent that the estimated cost to restore exceeds 2% of the
then actual replacement cost thereof, provided, however, that Landlord may not
terminate this Lease pursuant to this Paragraph 11.2B if one or more tenants of
the Project agree in writing to pay the amount by which the cost to restore the
damage exceeds such amount and subsequently deposit such amount with Landlord
within 30 days after Landlord has notified Tenant of its election to terminate
this Lease, or provides other reasonable assurances reasonably acceptable to
Landlord, of Tenant's ability to pay the excess amount as the work progresses.

          C.   The Premises are damaged by any peril within 12 months of the
last day of the Lease Term to such an extent that the estimated cost to restore
equals or exceeds an amount equal to six times the Base Monthly Rent then due;
provided, however, that Landlord may not terminate this Lease pursuant to this
Paragraph 11.2C if Tenant, at the time of such damage, has a then valid express
written option to extend the Lease Term and Tenant exercises such option to
extend the Lease Term within 15 days following the date of notice to Tenant that
the Lease will be terminated, unless Tenant exercises its option.

          D.   Either the Project or the Premises is damaged by any peril and,
because of the Laws then in force, (i) cannot be restored at reasonable cost to
substantially the same condition in which it was prior to such damage, or (ii)
cannot be used for the same use being made thereof before such damage if
restored as required by this Article.

          E.   As used herein, the following terms shall have the following
meanings (i) the term "Insured Peril" shall mean a peril actually insured

                                         11

<PAGE>
                                       LEASE

against or which Landlord is required by this Lease to insure against
which the insurance proceeds actually received by Landlord or which would be
received by Landlord if it had caused the insurance required by this Lease,
plus any sums Tenant is required by this Lease to contribute or which Tenant
elects to contribute to the restoration are sufficient (except for any
"deductible" amount specified by such insurance) to restore the Project under
then existing building codes to substantially the condition existing
immediately prior to the damage; and (a) the term "Uninsured Peril" shall
mean any peril which is not an Insured Peril.  Notwithstanding the foregoing,
if the "deductible" for earthquake or flood insurance exceeds 2% of the
replacement cost of the improvements insured, such peril shall be deemed an
"Uninsured Peril".

     11.3 TENANT'S RIGHT TO TERMINATE:  If the Premises are damaged by any
peril and Landlord does not elect to terminate this Lease or is not entitled
to terminate this Lease pursuant to Paragraph 11.2, then as soon as
reasonably practicable, Landlord shall furnish Tenant with the written
opinion of Landlord's architect or construction consultant as to when the
restoration work required of Landlord may be completed.  Tenant shall have
the right to terminate this Lease in the event any of the following occurs,
which right may be exercised only by delivery to Landlord of a written notice
of election to terminate within 10 days after Tenant receives from Landlord
the estimate of the time needed to complete such restoration.

          A.   The Premises are damaged by any peril and, in the reasonable
opinion of Landlord's architect or construction consultant, the restoration of
the Premises cannot be substantially completed within 270 days after the date of
such damage; or

          B.   The Premises are damaged by any peril within 12 months of the
last day of the Lease Term and, in the reasonable opinion of Landlord's
architect or construction consultant, the restoration of the Premises cannot be
substantially completed within 90 days after the date of such damage and such
damage renders unusable more than 30% of the Premises.

          C.   The Premises are not actually restored within 90 days following
the date for completion estimated by Landlord's architect.

     11.4 ABATEMENT OF RENT:  In the event of damage to the Premises which
does not result in the termination of this Lease, the Base Monthly Rent and
the Additional Rent shall be temporarily abated during the period following
the destruction and during restoration in proportion to the degree to which
Tenant's use of the Premises is impaired by such damage.  Tenant shall not be
entitled to any compensation or damages from Landlord for loss of Tenant's
business or property or for any inconvenience or annoyance caused by such
damage or restoration.  Tenant hereby waives the provisions of California
Civil Code Sections 1932(2) and 1933(4) and the provisions of any similar law
hereinafter enacted.

                                     ARTICLE 12

                                    CONDEMNATION


          12.1 LANDLORD'S TERMINATION RIGHT:  Landlord shall have the right to
terminate this Lease if, as a result of a taking by means of the exercise of the
power of eminent domain (including a voluntary sale or transfer by Landlord to a
condemnor under threat of condemnation), (i) all or any part of the Premises is
so taken, (ii) more than 10% of the Building Leasable Area is so taken, or (iii)
more than 50% of the Common Area is so taken.  Any such right to terminate by
Landlord must be exercised within a reasonable period of time, to be effective
as of the date possession is taken by the condemnor.

     12.2 TENANT'S TERMINATION RIGHT:  Tenant shall have the right to terminate
this Lease if, as a result of any taking by means of the exercise of the power
of eminent domain (including any voluntary sale or transfer by Landlord to any
condemnor under threat of condemnation), (i) 10% or more of the Premises is so
taken and that part of the Premises that remains cannot be restored within a
reasonable period of time and thereby made reasonably suitable for the continued
operation of the Tenant's business, or (ii) there is a taking affecting the
Common Area and, as a result of such taking, Landlord cannot provide parking
spaces within reasonable walking distance of the Premises equal in number to at
least 80% of the number of spaces allocated to Tenant by Paragraph 2.1, whether
by rearrangement of the remaining parking areas in the Common Area (including
construction of multi-deck parking structures or restriping for compact cars
where permitted by Law) or by alternative parking facilities on other land.
Tenant must exercise such right within a reasonable period of time, to be
effective on the date that possession of that portion of the Premises or Common
Area that is condemned is taken by the condemnor.

     12.3 RESTORATION AND ABATEMENT OF RENT:  If any part of the Premises or the
Common Area is taken by condemnation and this Lease is not terminated, then
Landlord shall restore the remaining portion of the Premises and Common Area and
interior improvements constructed by Landlord as they existed as of the
Commencement Date, excluding any Tenant's Alterations, Trade Fixtures and/or
personal property constructed or installed by Tenant.  Thereafter, except in the
case of a temporary taking, as of the date possession is taken the Base Monthly
Rent shall be reduced in the same proportion that the floor area of that part of
the Premises so taken (less any addition thereto by reason of any
reconstruction) bears to the original floor area of the Premises.

     12.4 TEMPORARY TAKING:  If any portion of the Premises is temporarily taken
for one year or less, this Lease shall remain in effect.  If any portion of the
Premises is temporarily taken by condemnation for a period which exceeds one
year or which extends beyond the natural expiration of the Lease Term, and such
taking materially and adversely affects Tenant's ability to use the Premises for
the Permitted Use, then Tenant shall have the right to terminate this Lease,
effective on the date possession is taken by the condemnor.

     12.5 DIVISION OF CONDEMNATION AWARD:  Any award made as a result of any
condemnation of the Premises or the Common Area shall belong to and be paid to
Landlord, and Tenant hereby assigns to Landlord all of its right, title and
interest in any such award; provided, however, that Tenant shall be entitled to
receive any condemnation award that is made directly to Tenant for the following
so long as the award made to Landlord is not thereby reduced: (i) for the taking
of Tenant's Property or Trade Fixtures belonging to Tenant, (ii) for the
interruption of Tenant's business or its moving costs, (iii) for loss of
Tenant's goodwill; or (iv) for

                                         12

                                       LEASE


any temporary taking where this Lease is not terminated as a result of such
taking.  The rights of Landlord and Tenant regarding any condemnation shall be
determined as provided in this Article, and each party hereby waives the
provisions of California Code of Civil Procedure Section 1265.130 and the
provisions of any similar law hereinafter enacted allowing either party to
petition the Superior Court to terminate this Lease in the event of a partial
taking of the Premises.

                                     ARTICLE 13

                                DEFAULT AND REMEDIES


     13.1 EVENTS OF TENANT'S DEFAULT:  Tenant shall be in default of its
obligations under this Lease if any of the following events occurs (an "Event of
Tenant's Default"):

          A.   Tenant shall have failed to pay Base Monthly Rent or Additional
Rent when due, and such failure is not cured within 3 days after delivery of
written notice from Landlord specifying such failure to pay; or

          B.   Tenant shall have failed to perform any term, covenant, or
condition of this Lease except those requiring the payment of Base Monthly Rent
or Additional Rent, and Tenant shall have failed to cure such breach within 30
days after written notice from Landlord specifying the nature of such breach
where such breach could reasonably be cured within said 30 day period, or if
such breach could not be reasonably cured within said 30 day period, Tenant
shall have failed to commence such cure within said 30 day period and thereafter
continue with due diligence to prosecute such cure to completion within such
time period as is reasonably needed; or

          C.   Tenant shall have sublet the Premises or assigned its interest in
the Lease in violation of the provisions contained in Article 14; or

          D.    Tenant shall have abandoned the Premises and failed to perform
its obligation hereunder; or

          E.   The occurrence of the following: (i) the making by Tenant of any
general arrangements or assignments for the benefit of creditors; (ii) Tenant
becomes a "debtor" as defined in 11 USC Section 101 or any successor statute
thereto (unless, in the case of a petition filed against Tenant, the same is
dismissed within 60 days); (iii) the appointment of a trustee or receiver to
take possession of substantially all of Tenant's assets located at the Premises
or of Tenant's interest in this Lease, where possession is not restored to
Tenant within 30 days; or (iv) the attachment, execution or other judicial
seizure of substantially all of Tenant's assets located at the Premises or of
Tenant's interest in this Lease, where such seizure is not discharged within 30
days; provided, however, in the event that any provision of this Section 13.1E
is contrary to any applicable Law, such provision shall be of no force or
effect; or

          F.   Tenant shall have failed to deliver documents required of it
pursuant to Paragraph 15.4 or 15.6 within the time periods specified therein.

     13.2 LANDLORD'S REMEDIES:  If an Event of Tenant's Default occurs, Landlord
shall have the following remedies, in addition to all other rights and remedies
provided by any Law or otherwise provided in this Lease, to which Landlord may
resort cumulatively or in the alternative:

          A.   Landlord may keep this Lease in effect and enforce by an action
at law or in equity all of its rights and remedies under this Lease, including
(i) the right to recover the rent and other sums as they become due by
appropriate legal action, (ii) the right to make payments required of Tenant or
perform Tenant's obligations and be reimbursed by Tenant for the cost thereof
with interest at the Agreed Interest Rate from the date the sum is paid by
Landlord until Landlord is reimbursed by Tenant, and (iii) the remedies of
injunctive relief and specific performance to compel Tenant to perform its
obligations under this Lease.  Notwithstanding anything contained in this Lease,
in the event of a breach of an obligation by Tenant which results in a condition
which poses an imminent danger to safety of persons or damage to property, an
unsightly condition visible from the exterior of the Building, or a threat to
insurance coverage, then if Tenant does not cure such breach within 3 days after
delivery to it of written notice from Landlord identifying the breach, Landlord
may cure the breach of Tenant and be reimbursed by Tenant for the cost thereof
with interest at the Agreed Interest Rate from the date the sum is paid by
Landlord until Landlord is reimbursed by Tenant.

          B.   Landlord may enter the Premises and release them to third parties
for Tenant's account for any period, whether shorter or longer than the
remaining Lease Term.  Tenant shall be liable immediately to Landlord for all
costs Landlord incurs in releasing the Premises, including brokers' commissions,
expenses of altering and preparing the Premises required by the releasing.
Tenant shall pay to Landlord the rent and other sums due under this Lease on the
date the rent is due, less the rent and other sums Landlord received from any
releasing.  No act by Landlord allowed by this subparagraph shall terminate this
Lease unless Landlord notifies Tenant in writing that Landlord elects to
terminate this Lease.  Notwithstanding any releasing without termination,
Landlord may later elect to terminate this Lease because of the default by
Tenant.

          C.   Landlord may terminate this Lease by giving Tenant written notice
of termination, in which event this Lease shall terminate on the date set forth
for termination in such notice.  Any termination under this Paragraph 13.2C
shall not relieve Tenant from its obligation to pay sums then due Landlord or
from any claim against Tenant for damages or rent previously accrued or then
accruing.  In no event shall any one or more of the following actions by
Landlord, in the absence of a written election by Landlord to terminate this
Lease, constitute a termination of this Lease: (i) appointment of a receiver or
keeper in order to protect Landlord's interest hereunder; (ii) consent to any
subletting of the Premises or assignment of this Lease by Tenant, whether
pursuant to the provisions hereof or otherwise; or (iii) any other action by
Landlord or Landlord's Agents intended

                                         13

<PAGE>

                                       LEASE

to mitigate the adverse effects of any breach of this Lease by Tenant, including
without limitation any action taken to maintain and preserve the Premises or any
action taken to relet the Premises or any portions thereof to the extent such
actions do not affect a termination of Tenant's right to possession of the
Premises.

          D.   In the event Tenant breaches this Lease and abandons the
Premises, this Lease shall not terminate unless Landlord gives Tenant written
notice of its election to so terminate this Lease.  No act by or on behalf of
Landlord intended to mitigate the adverse effect of such breach, including those
described by Paragraph 13.C, shall constitute a termination of Tenant's right to
possession unless Landlord gives Tenant written notice of termination.  Should
Landlord not terminate this Lease by giving Tenant written notice, Landlord may
enforce all its rights and remedies under this Lease, including the right to
recover the rent as it becomes due under the Lease as provided in California
Civil Code Section 1951.4.

          E.   In the event Landlord terminates this Lease, Landlord shall be
entitled, at Landlord's election, to damages in an amount as set forth in
California Civil Code Section 1951.2 as in effect on the Effective Date.  For
purposes of computing damages pursuant to California Civil Code Section 1951.2.,
(i) an interest rate equal to the Agreed Interest Rate shall be used where
permitted, and (ii) the term "rent" includes Base Monthly Rent and Additional
Rent.  Such damages shall include:

               (1)  The worth at the time of award of the amount by which the
unpaid rent for the balance of the term after the time of award exceeds the
amount of such rental loss that Tenant proves could be reasonably avoided,
computed by discounting such amount at the discount rate of the Federal Reserve
Bank of San Francisco at the time of award plus one percent (1%); and

               (2)  Any other amount necessary to compensate Landlord for all
detriment proximately caused by Tenant's failure to perform Tenant's obligations
under this Lease, or which in the ordinary course of things would be likely to
result therefrom, including the following: (i) expenses for cleaning, repairing
or restoring the Premises; (ii) expenses for altering, remodeling or otherwise
improving the Premises for the purpose of reletting, including installation of
leasehold improvements (whether such installation be funded by a reduction of
rent, direct payment or allowance to a new tenant, or otherwise); (iii) broker's
fees, advertising costs and other expenses of reletting the Premises; (i) costs
of carrying the Premises, such as taxes, insurance premiums, utilities and
security precautions; (v) expenses in retaking possession of the Premises; and
(vi) attorneys' fees and court costs incurred by Landlord in retaking possession
of the Premises and in releasing the Premises or otherwise incurred as a result
of Tenant's default.

          F.   Nothing in this 13.2 shall limit Landlord's right to
indemnification from Tenant as provided in Paragraph 17.2 and Paragraph 10.3.
Any notice given by Landlord in order to satisfy the requirements of
Paragraph 13.1A or Paragraph 13.1B above shall also satisfy the notice
requirements of California Code of Civil Procedure Section 1161 regarding
unlawful detainer proceedings, if it is delivered in the form and by means
described in said Code Sections.

     13.3 WAIVER:  One party's consent to or approval of any act by the other
party requiring the first party's consent or approval shall not be deemed to
waive or render unnecessary the list party consent to or approval of any
subsequent similar act by the other party.  The receipt by Landlord of any rent
or payment with or without knowledge of the breach of any other provision hereof
shall not be deemed a waiver of any such breach unless such waiver is in writing
and signed by Landlord.  No delay or omission in the exercise of any right or
remedy accruing to either party upon any breach by the other party under this
Lease shall impair such right or remedy or be construed as a waiver of any such
breach theretofore or thereafter occurring.  The waiver by either party of any
breach of any provision of this Lease shall not be deemed to be a waiver of any
subsequent breach of the same or of any other provisions herein contained.

     13.4 LIMITATION ON EXERCISE OF RIGHT:  At any time that an Event of
Tenant's Default has occurred and remains uncured, (i) it shall not be
unreasonable for Landlord to deny or withhold any consent or approval
requested of it by Tenant which Landlord would otherwise be obligated to give
unless as a consequence of the transaction the Default will be cured, and
(ii) Tenant may not exercise any option to extend, right to terminate this
Lease, or other right granted to it by this Lease which would otherwise be
available to it.

     13.5 WAIVER BY TENANT OF CERTAIN REMEDIES.  Tenant waives the provisions
of Sections 1932(l), 1941 and 1942 of the California Civil Code and any
similar or successor law regarding Tenant's right to terminate this Lease or
to make repairs and deduct the expenses of such repairs from the rent due
under this Lease.  Tenant hereby waives any right of redemption or relief
from forfeiture under the laws of the State of California, or under any other
present or future law, including the provisions of Sections 1174 and 1179 of
the California Code of Civil Procedure.

                                     ARTICLE 14

                             ASSIGNMENT AND SUBLETTING


     14.1 TRANSFER BY TENANT:  The following provisions shall apply to any
assignment, subletting or other transfer by Tenant or any subtenant or assignee
or other successor in interest of the original Tenant (collectively referred to
in this Paragraph 14.1 as "Tenant"):

          A.   Tenant shall not do any of the following (collectively referred
to herein as a "Transfer"), whether voluntarily, involuntarily or by operation
of law, without the prior written consent of Landlord, which consent shall not
be unreasonably withheld or delayed: (i) sublet all or any part of the Premises
or allow it to be sublet, occupied or used by any person or entity other than
Tenant; (ii) assign its interest in this Lease; (iii) mortgage or encumber the
Lease (or otherwise use the Lease as a security device) in any manner; or (iv)
materially amend or modify an assignment, sublease or other transfer that has
been previously approved by Landlord.  Tenant shall reimburse Landlord for all
reasonable


                                         14

<PAGE>

                                       LEASE

costs and attorney fees incurred by Landlord in connection with the
evaluation, processing, and/or documentation of any requested Transfer,
whether or not Landlord's consent is granted.  Landlord's reasonable costs
shall include the cost of any review or investigation performed by Landlord
or consultant acting on Landlord's behalf of (i) Hazardous Materials (as
defined in Section 7.2E of this Lease) used, stored, released, or disposed of
by the potential Subtenant or Assignee, and/or (ii) violations of Hazardous
Materials Law (as defined in Section 7.2E of this lease) by the Tenant or the
proposed Subtenant or Assignee. Any Transfer so approved by Landlord shall
not be effective until Tenant has delivered to Landlord an executed
counterpart of the document evidencing the Transfer which (i) is in a form
reasonably approved by Landlord, (ii) contains the same terms and conditions
as stated in Tenant's notice given to Landlord pursuant to Paragraph 14.1B,
and (iii) in the case of an assignment of the Lease, contains the agreement
of the proposed transferee to assume all obligations of Tenant under this
Lease arising after the effective date of such Transfer and to remain jointly
and severally liable therefor with Tenant.  Any attempted Transfer without
any required Landlord's consent shall constitute an Event of Tenant's Default
and shall be voidable at Landlord's option.  Landlord's consent to any one
Transfer shall not constitute a waiver of the provisions of this Paragraph
14.1 as to any subsequent Transfer or a consent to any subsequent Transfer.
No Transfer, even with the consent of Landlord, shall relieve Tenant of its
personal and primary obligation to pay the rent and to perform all of the
other obligations to be performed by Tenant hereunder.  The acceptance of
rent by Landlord from any person shall not be deemed to be a waiver by
Landlord of any provision of this Lease nor to be a consent to any Transfer.

          B.   At least 15 days before a proposed Transfer is to become
effective, Tenant shall give Landlord written notice of the proposed terms of
such Transfer and request Landlord's approval, which notice shall include the
following: (i) the name and legal composition of the proposed transferee;
(ii) a current best available Financial statement of the transferee, best
available financial statements of the transferee covering the preceding three
years if the same exist, and (if available) an audited financial statement of
the transferee for a period ending not more than one year prior to the
proposed effective date of the Transfer, all of which statements are prepared
in accordance with generally accepted accounting principles; (iii) the nature
of the proposed transferee's business to be carried on in the Premises; (iv)
all consideration to be given on account of the Transfer; (v) a current
financial statement of Tenant; and (vi) an accurately filled out response to
Landlord's standard Hazardous Materials Questionnaire in use by Landlord with
other tenants at the time of the Transfer. Tenant shall provide to Landlord
such other information as may be reasonably requested by Landlord within
seven days after Landlord's receipt of such notice from Tenant.  Landlord
shall respond in writing to Tenant's request for Landlord's consent to a
Transfer within the later of (i) 10 days of receipt of such request together
with the required accompanying documentation, or (ii) seven days after
Landlord's receipt of all information which Landlord reasonably requests
within seven days after it receives Tenant's first notice regarding the
Transfer in question.  If Landlord fails to respond in writing within said
period, Landlord will be deemed to have withheld consent to such Transfer.
Tenant shall immediately notify Landlord of any material modification to the
proposed terms of such Transfer.

          C.   In the event that Tenant seeks to assign or sublease for the
balance of the Lease Term, Landlord shall have the right to terminate this Lease
or, in the case of a sublease of less than all of the Premises, terminate this
Lease as to that part of the Premises proposed to be so sublet, either (i) on
the condition that the proposed transferee immediately enter into a direct lease
of the Premises with Landlord (or, in the case of a partial sublease, a lease
for the portion proposed to be so sublet) on the same terms and conditions
contained in Tenant's notice, or (ii) so that Landlord is thereafter free to
lease the Premises (or, in the case of a partial sublease, the portion proposed
to be so sublet) to whomever it pleases on whatever terms are acceptable to
Landlord.  In the event Landlord elects to so terminate this Lease, then (i) if
such termination is conditioned upon the execution of a lease between Landlord
and the proposed transferee, Tenant's obligations under this Lease shall not be
terminated until such transferee executes a new lease with Landlord, enters into
possession and commences the payment of rent, and (ii) if Landlord elects simply
to terminate this Lease (or, in the case of a partial sublease, terminate this
Lease as to the portion to be so sublet), the Lease shall so terminate in its
entirety (or as to the space to be so sublet) fifteen (15) days after Landlord
has notified Tenant in writing of such election.  Upon such termination, Tenant
shall be released from any further obligation under this Lease if it is
terminated in its entirety, or shall be released from any further obligation
under the Lease with respect to the space proposed to be sublet in the case of a
proposed partial sublease.  In the case of a partial termination of the Lease,
the Base Monthly Rent and Tenant's Share shall be reduced to an amount which
bears the same relationship to the original amount thereof as the area of that
part of the Premises which remains subject to the Lease bears to the original
area of the Premises.  Landlord and Tenant shall execute a cancellation and
release with respect to the Lease to effect such termination.  Landlord shall
not unreasonably withhold consent to a change in use in order to accommodate any
Transfer which does not pose a health or safety risk to the Project and conforms
to all applicable laws.

          D.   If Landlord consents to a Transfer proposed by Tenant or if
Landlord's consent is not required, Tenant may enter into such Transfer, and if
Tenant does so, the following shall apply:

               (1)  Tenant shall not be released of its liability for the
performance of all of its obligations under the Lease.

               (2)  If Tenant assigns its interest in this Lease, then Tenant
shall pay to Landlord 50% of all Subrent (as defined in Paragraph 14.1D)(5))
received by Tenant over and above (i) the assignee's agreement to assume the
obligations of Tenant under this Lease, and (ii) all Permitted Transfer Costs
related to such assignment.  In the case of assignment, the amount of Subrent
owed to Landlord shall be paid to Landlord on the same basis, whether periodic
or in lump sum, that such Subrent is paid to Tenant by the assignee.

          (3)  If Tenant sublets any part of the Premises, then with respect to
the space so

                                         15

<PAGE>

                                       LEASE

subleased, Tenant shall pay to Landlord 50% of the positive difference, if any,
between (i) all Subrent paid by the subtenant to Tenant, after deduction of (ii)
the sum of all base Monthly Rent and Additional Rent allocable to the space
sublet and all Permitted Transfer Costs related to such sublease.  Such amount
shall be paid to Landlord on the same basis, whether periodic or in lump sum,
that such Subrent is paid to Tenant by its subtenant.  In calculating Landlord's
share of any periodic payments, all Permitted Transfer Costs shall be first
recovered by Tenant.

          (4)  Tenant's obligations under this Paragraph 14.1D shall survive any
Transfer, and Tenant's failure to perform its obligations hereunder shall be an
Event of Tenant's Default.  At the time Tenant makes any payment to Landlord
required by this Paragraph 14.1D, Tenant shall deliver an itemized statement of
the method by which the amount to which Landlord is entitled was calculated,
certified by Tenant as true and correct.  Landlord shall have the right at
reasonable intervals to inspect Tenant's books and records relating to the
payments due hereunder.  Upon request therefor, Tenant shall deliver to Landlord
copies of all bills, invoices or other documents upon which its calculations are
based.  Landlord may condition its approval of any Transfer requiring Landlord's
consent upon obtaining a certification from both Tenant and the proposed
transferee of all Subrent and other amounts that are to be paid to Tenant in
connection with such Transfer.

          (5)  As used in this Paragraph 14.1D, the term "Subrent" shall mean
any consideration of any kind received, or to be received, by Tenant as a
consideration for the Transfer, if such sums are related to Tenant's interest
in this Lease or in the Premises.  As used in this Paragraph 14.1D, the term
"Permitted Transfer Costs" shall mean (i) all reasonable leasing commissions
paid to third parties not affiliated with Tenant in order to obtain the
Transfer in question, (ii) all reasonable attorneys' fees incurred by Tenant
with respect to the Transfer in question, (iii) all other reasonable cost
paid or incurred by Tenant to perform its obligations under the Transfer
document/sublease reflected in the Subrent.

          E.   If Tenant is a corporation, the following shall be deemed a
voluntary assignment of Tenant" interest in this Lease: (i) any dissolution,
merger, consolidation, or other reorganization of or affecting Tenant, whether
or not Tenant is the surviving corporation; and (ii) if the capital stock of
Tenant is not publicly traded, the sale or transfer to one person or entity (or
to any group of related persons or entities) stock possessing more than 50% of
the total combined voting power of all classes of Tenant's capital stock issued,
outstanding and entitled to vote for the election of directors.  If Tenant is a
partnership, any withdrawal or substitution (whether voluntary, involuntary or
by operation of law, and whether occurring at one time or over a period of time)
of any partner owning 25% or more (cumulatively) of any interest in the capital
or profits of the partnership, or the dissolution of the partnership, shall be
deemed a voluntary assignment of Tenant's interest in this Lease.

          F.   Notwithstanding anything contained in Paragraph 14.1, so long as
Tenant otherwise complies with the provisions of Paragraph 14.1 Tenant may enter
into any of the following transfers (a "Permitted Transfer") without Landlord's
prior written consent, and Landlord shall not be entitled to terminate the Lease
pursuant to Paragraph 14.1C or to receive any part of any Subrent resulting
therefrom that would otherwise be due it pursuant to Paragraph 14.1D:

               (1)  Tenant may sublease all or part of the Premises or assign
its interest in this Lease to any corporation which controls, is controlled by,
or is under common control with the original Tenant to this Lease by means of an
ownership interest of more than 50%;

               (2)  Tenant may assign its interest in the Lease to a corporation
which results from a merger, consolidation or other reorganization in which
Tenant is not the surviving corporation, so long as the surviving corporation
has a net worth at the time of such assignment that is equal to or greater than
the net worth of Tenant immediately prior to such transaction; and

               (3)  Tenant may assign this Lease to a corporation which
purchases or otherwise acquires all or substantially all of the stock of Tenant
or substantially all of the assets of Tenant, so long as the Tenant after the
transaction has a net worth at the time of such assignment that is equal to or
greater than the net worth of Tenant immediately prior to such transaction.

     14.2 TRANSFER BY LANDLORD:  Landlord and its successors in interest shall
have the right to transfer their interest in this Lease and the Project at any
time and to any person or entity.  In the event of any such transfer, the
Landlord originally named herein (and, in the case of any subsequent transfer,
the transferor) from the date of such transfer, shall be automatically relieved,
without any further act by any person or entity, of all liability for the
performance of the obligations of the Landlord hereunder which may accrue after
the date of such transfer and which are assumed by Landlord's transferee.  After
the date of any such transfer, term "Landlord" as used herein shall mean the
transferee of such interest in the Premises.

                                     ARTICLE 15

                                 GENERAL PROVISIONS

     15.1 LANDLORD'S RIGHT TO ENTER:  Landlord and its agents may enter the
Premises at any reasonable time after giving at least 24 hours' prior notice
to Tenant (and immediately in the case of emergency) for the purpose of: (i)
inspecting the same; (ii) posting notices of non-responsibility; (iii)
supplying any service to be provided by Landlord to Tenant; (iv) showing the
Premises to prospective purchasers, mortgagees or tenants; (v) making
necessary alterations, additions or repairs; (vi) performing Tenant's
obligations when Tenant has failed to do so after written notice from
Landlord; (vii) placing upon the Premises ordinary "for lease" signs or "for
sale" signs (clearly indicating the Project, not the business, is for sale)
and (viii) responding to an emergency. Landlord shall have the right to use
any and all means Landlord may deem necessary and proper to enter the
Premises in an emergency.  Any entry into the Premises obtained by Landlord
in accordance with this Paragraph 15.1 shall not be a forcible or unlawful

                                         16

<PAGE>

entry into, or a detainer of, the Premises, or an eviction, actual or
constructive, of Tenant from the Premises.

     15.2 SURRENDER OF THE PREMISES:  Upon the expiration or sooner termination
of this Lease, Tenant shall vacate and surrender the Premises to Landlord in the
same condition as existed at the Commencement Date, (unless Landlord has agreed,
prior to the construction of such Tenant Alterations, that such will not be
required to be removed at the termination of the Lease) except for (i)
reasonable wear and tear, (ii) damage caused by any peril or condemnation, and
(iii) contamination by Hazardous Material for which Tenant is not responsible
pursuant to Paragraph 7.2A or Paragraph 7.2B. In this regard, normal wear and
tear shall be construed to mean wear and tear caused to the Premises by the
natural aging process which occurs in spite of prudent application of the best
standards for maintenance, repair and janitorial practices, and does not include
items of neglected or deferred maintenance required of Tenant by the Lease. In
any event, Tenant shall cause the following to be done prior to the expiration
or the sooner termination of this Lease: (i) all interior walls shall be
cleaned; (ii) all tiled floors shall be cleaned and waxed; (iii) all carpets
shall be cleaned and shampooed; (iv) all broken, marred, stained or
nonconforming acoustical ceiling tiles shall be replaced; (v) all windows shall
be washed; (vi) the HVAC system shall be serviced by a reputable and licensed
service firm and left in good operating condition and repair as so certified by
such firm; and (vii) the plumbing and electrical systems and lighting shall be
placed in good order and repair (including replacement of any burned out,
discolored or broken light bulbs, ballasts, or lenses).  If Landlord so
requests, Tenant shall, prior to the expiration or sooner termination of this
Lease, (i) remove any Tenant's Alterations which Tenant is required to remove
pursuant to Paragraph 15.2 and repair all damage caused by such removal, and
(ii) return the Premises or any part thereof to its original configuration
existing as of the time the Premises were delivered to Tenant (unless Landlord
has agreed, prior to the construction of such Tenant Alterations, that such will
not be required to be removed at the termination of the Lease).  If the Premises
are not so surrendered at the termination of this Lease, Tenant shall be liable
to Landlord for all costs incurred by Landlord in returning the Premises to the
required condition, plus interest on all costs incurred at the Agreed Interest
Rate.  Tenant shall indemnify Landlord against loss or liability resulting from
delay by Tenant in so surrendering the Premises, including, without limitation,
any claims made by any succeeding tenant or losses to Landlord due to lost
opportunities to lease to succeeding tenants.

     15.3 HOLDING OVER:  This Lease shall terminate without further notice at
the expiration of the Lease Term.  Any holding over by Tenant after expiration
of the Lease Term shall not constitute a renewal or extension of the Lease or
give Tenant any rights in or to the Premises except as expressly provided in
this Lease.  Any holding over after such expiration with the written consent of
Landlord shall be construed to be a tenancy from month to month on the same
terms and conditions herein specified insofar as applicable except that Base
Monthly Rent shall be increased to an amount equal to 150% of the Base Monthly
Rent payable during the last full calendar month of the Lease Term.

     15.4 SUBORDINATION:  The following provisions shall govern the relationship
of this Lease to any Security Instrument:

          A.   The Lease is subject and subordinate to all Security Instruments
existing as of the Effective Date.  However, if any Lender so requires, this
Lease shall become prior and superior to any such Security Instrument.  Upon
written request from Tenant, Landlord shall use all reasonable efforts to obtain
a non-disturbance agreement from Landlord's Lender on the Lender's standard
form. All costs, if any, in obtaining agreement shall be paid by Tenant.

          B.   At Landlord's election, this Lease shall become subject and
subordinate to any Security Instrument created after the Effective Date.
Notwithstanding such subordination, Tenant's right to quiet possession of the
Premises shall not be disturbed so long as Tenant is not in default and performs
all of its obligations under this Lease, unless this Lease is otherwise
terminated pursuant to its terms.

          C.   Tenant shall upon request execute any document or instrument
reasonably required by any Lender to make this Lease either prior or subordinate
to a Security Instrument, which may include such other matters as the Lender
customarily and reasonably requires in connection with such agreements,
including provisions that the Lender not be liable for (i) the return of any
security deposit unless the Lender receives it from Landlord, and (ii) any
defaults on the part of Landlord occurring prior to the time the Lender takes
possession of the Project in connection with the enforcement of its Security
Instrument.  Tenant's failure to execute any such document or instrument within

to obtain possession of the Premises by power of sale or judicial foreclosure or
other appropriate legal proceedings, if such should prove necessary to effect a
cure.  Tenant shall attorn to any purchaser of the Premises at any foreclosure
sale or private sale conducted pursuant to any Security Instrument encumbering
the Premises, or to any grantee or transferee designated in any deed given in
lieu of foreclosure.

the normal practice of Tenant, shall be audited by an independent certified

of default may be delivered by fax.

     15.9  ATTORNEYS' FEES:  In the event either Landlord or Tenant shall
bring any action or legal proceeding for an alleged breach of any provision
of this Lease, to recover rent, to terminate this Lease or otherwise to

provisions shall remain in full force and effect.  Time is of the essence

time of performance is a factor.  The captions used in this Lease are for
convenience only and shall not be considered in the construction or

Lease shall be construed and enforced in accordance with the laws of the

or less than the amount of area reflected in this Lease, and (iv) any such
subsequent determination that the area is more or less than shown in this
Lease shall not result in a change in any of the computations of rent,
improvement allowances, or other matters described in this Lease where area
is a factor. Where a party hereto is obligated not to perform any act, such
party is also obligated to restrain any others within its control from
performing said act, including the Agents of such party.  Landlord shall not
become or be deemed a partner or a joint venturer with Tenant by reason of
the provisions of this Lease.

     15.12  TERMINATION BY EXERCISE OF RIGHT:  If this Lease is terminated
pursuant to its terms by the proper exercise of a right to terminate
specifically granted to Landlord or Tenant by this Lease, then this Lease
shall terminate on a date thereafter selected by Tenant, which date shall not
be more than 180 days after the date the right to terminate is properly
exercised (unless another date is specified in that part of the Lease
creating the right, in which event the date so specified for termination
shall prevail), the rent and all other charges due hereunder shall be
prorated as of the date of termination, and neither Landlord nor Tenant shall
have any further rights or obligations under this Lease except for those that
have accrued


                                       18

warrants to the other that it has not had any dealings with any real estate

than to the Retained Real Estate Brokers described in SECTION S of the
Summary, and (ii) agrees to indemnify, defend, and hold harmless the other
party from any claim for any such commission or fees which result from the
actions of the indemnifying party.  Landlord shall be responsible for the
payment of any commission owed to the Retained Real Estate Brokers if there
is a separate written commission agreement between Landlord and the Retained
Real Estate Brokers for the payment of a commission as a result of the
execution of this Lease.

     15.14  FORCE MAJEURE:  Any prevention, delay or stoppage due to strikes,

materials, fuels or reasonable substitutes therefor, governmental
restrictions, regulations, controls, action or inaction, civil commotion,

performance, for a period equal to the period of any said prevention, delay
or stoppage, of any obligation hereunder except the obligation of Tenant or
Landlord to pay rent or any other sums due hereunder.

     15.15  ENTIRE AGREEMENT:  This Lease constitutes the entire agreement
between the parties, and there are no binding agreements or representations
between the parties except as expressed herein.  Tenant acknowledges that
neither Landlord nor Landlord's Agents has made any legally binding
representation or warranty as to any matter except those expressly set forth
herein, including any warranty as to (i) whether the Premises may be used for
Tenant's intended use under existing Law, (ii) the suitability of the
Premises or the Project for the conduct of Tenant's business, or (iii) the

and Tenant affecting this Lease, and this Lease supercedes and cancels any
and all previous negotiations, arrangements, brochures, agreements and
understandings, if any, between Landlord and Tenant or displayed by Landlord
to Tenant with respect to the subject matter of this Lease.  This instrument
shall not be legally binding until it is executed by both Landlord and
Tenant.  No subsequent change or addition to this Lease shall be binding
unless in writing and signed by Landlord and Tenant.

<PAGE>

                              FIRST ADDENDUM TO LEASE

     THIS FIRST ADDENDUM is dated for reference purposes as December 6, 1996,
and is made a part of that Lease Agreement (the "Lease") dated December 6,
1996, by and between SAN JOSE ACQUISITION CO., L.L.C., a Delaware limited
liability company ("Landlord") and QUICKTURN DESIGN SYSTEMS, INC., a Delaware
corporation ("Tenant") affecting certain real property commonly known as 2610
Orchard Parkway and 55 W. Trimble Road, San Jose, California , with reference
to the following facts:

     1.   TENANT IMPROVEMENT ALLOWANCES:

          A.   The term "First Level Tenant Improvement Allowance" shall mean
the maximum amount Landlord is required to spend toward the payment of
Interior Improvement Costs for all Interior Improvements constructed in the
Premises, which amount is $729,075.00 (i.e., $5.00 per square foot for
Tenant's Gross Leasable Area within the entire Premises).

          B.   A second level Tenant Improvement Allowance ("Second Level
Tenant Improvement Allowance") of $291,630 (i.e., $2.00 per square foot for
Tenant's Gross Leasable Area within the entire Premises) shall be made
available for an increase in the Base Monthly Rent as provided for in
paragraph 2 of this Addendum To Lease.

          C.   The First Level Tenant Improvement Allowance plus the Second
Level Tenant Improvement Allowance shall be termed the "Total Tenant
Improvement Allowance" consisting of $1,020,705.00 (i.e., $7.00 per square
foot for Tenant's Gross Leasable Area within the entire Premise).

          D.   Landlord shall not be obligated to provide future use of any
Tenant Improvement Allowance not spent within ninety (90) days after the
Commencement Date, subject to delays caused by Landlord, its employees, its
contractors, or Agents.

     2.   ADJUSTMENTS TO THE BASE MONTHLY RENT: The Base Monthly Rent as
provided for in Article 3 of the Lease shall be adjusted as follows:

          A.   For every increment of $145,815 (i.e., $0.0166 per square foot
of Gross Leasable Area), or proportion thereof of the Second Level Tenant
Improvement Allowance that Tenant elects to spend for the payment of the
Interior Improvement Costs as defined in Exhibit B, "Interior Improvement
Agreement", the Base Monthly Rent shall increase $0.0166 per square foot per
month.  As an example, if $218,722.50 of Second Level Tenant Improvement
Allowance is spent, the Base Monthly Rent shall increase $3,630.79 per month.

          B.   No credit in the Base Monthly Rent shall be made if a portion
of the Tenant Improvement Allowance is not spent.

     3.   CALCULATION OF FINAL PREPAID RENT AND SECURITY DEPOSIT:
Notwithstanding the provisions of Section L and M of the Summary to this
Lease, upon execution of Exhibit D ("Punch List Agreement"), Tenant shall
increase: (i) the Prepaid Rent to an amount equal to the first month's Base
Monthly Rent; and, (ii) the Security Deposit to an amount equal to the last
month's Base Monthly Rent, as those amounts are finally calculated as
provided for in Paragraph 2 of this First Addendum to Lease.

     4.   TENANT'S RIGHT OF FIRST NEGOTIATION FOR ADDITIONAL SPACE:

          A.   GRANT AND RIGHT OF FIRST NEGOTIATION: Landlord hereby grants
to Tenant a Right of First Negotiation regarding the leasing of the "First
Negotiation Space", which consists of the portion of the Building which is
identified and described on Exhibit "A" as the First Negotiation Space, being
approximately 60,633 square feet of rentable space commonly known as 2630
Orchard Parkway, San Jose, California on the terms

<PAGE>

contained in this Paragraph.

          B.   NEGOTIATION NOTICE: If Landlord proposes to lease all or part
of the First Negotiation Space at any time after the Effective Date of this
Lease and before the expiration or earlier termination of this Right of First
Negotiation, Landlord shall notify Tenant in writing (the "Negotiation
Notice") of the following basic business terms upon which Landlord would be
willing to lease the First Negotiation Space; (i) the portion of the First
Negotiation Landlord propose to lease (the "Offered Space"), (ii) the term of
the proposed lease; (iii) the

<PAGE>

Page Two


tenant improvements Landlord is willing to construct or that it will require
be constructed and the contribution Landlord is willing to make to pay for
such tenant improvements; (iv) the rent for the terms of the lease or formula
to be used to determine such rent, and (v) any other material business terms
Landlord elects to specify.

          C.   NEGOTIATION PERIOD: Tenant shall have fifteen (15) days (the
"Negotiation Period") from the Negotiation Notice within which to accept the
terms specified in the Negotiation Notice or to conduct negotiations with
Landlord regarding Tenant's leasing of the Offered Space, whether on the
terms set forth in Landlord's notice or otherwise.

          D.   DUTIES DURING NEGOTIATION PERIOD: During the Negotiation
Period, Landlord and Tenant will negotiate in good faith in an attempt to
agree on a lease of the Offered Space.  Neither Landlord nor Tenant shall be
bound to agree to or accept any terms and conditions for such lease except
those which each party, in its sole discretion, wishes to agree to.  "Good
Faith" in such negotiations does not require either party to make concessions
to the other party's position, but only requires that each party give the
other party a reasonable opportunity, within the Negotiation Period, to
present and discuss the party's proposals.  Landlord is not bound to agree to
any or all of the terms set forth in the Negotiation Notice if Tenant does
not accept such terms without change and Landlord determines during
negotiations that one or more of said terms is not in landlord's best
interest.

          E.   LANDLORD'S RIGHT TO LEASE ABSENT AGREEMENT: If Tenant does not
accept the terms set forth in the Negotiation Notice and Landlord and Tenant
do not reach agreement in writing on other terms for Tenant to lease the
Offered Space within the Negotiation Period, Landlord thereafter shall have
the right to offer the Offered Space to any third party, on such terms and
conditions as Landlord may elect which are not more favorable to Tenant than
those contained in Landlord's notice, provided such transaction is
consummated within 180 days following the end of the Negotiation Period and
in such case Landlord shall not thereafter, have any duty to further offer
the Offered Space to Tenant.

          F.   TERMINATION: The right granted to Tenant in this Paragraph is
personal to Tenant, and may not be assigned by Tenant to any third party,
either alone on in conjunction with an assignment of this Lease or a sublease
of all or any part of the Premises.  The rights granted to Tenant under this
paragraph shall terminate upon the earliest of the following to occur: (i)
the expiration or earlier termination of the Lease; (ii) any assignment by
Tenant of its interest in this Lease; (iii) any subletting by Tenant of
substantially all of the Premises for substantially all of the remainder of
the Lease Term, (iv) the termination of this right by default as set forth in
Subparagraph G below, or (v) as to any Offered Space, when the Negotiation
Period ends without Tenant and Landlord reaching a written agreement for
Tenant to lease the Offered Space.

          G.   TERMINATION BY DEFAULT: The rights of Tenant under this
Paragraph shall not be effective at any time when Tenant is in default under
this Lease beyond any applicable cure period provided in this Lease.  If
Tenant, with the agreement of landlord, shall nevertheless cure such default,
then the rights provided hereunder shall be reinstated, but any transaction
to lease any or all of the First Negotiation Space entered into by Landlord
during such period of default shall be valid and Tenant shall have no further
Right of First Negotiation as to any such space leased by Landlord while
Tenant is in default under this Subparagraph.

          H.   NO RIGHT TO NEGOTIATION FOR RENEWAL OR EXTENSION SPACE: The
right

<PAGE>

granted to Tenant by this Paragraph shall not arise on account of or in
connection with the renewal or extension of the term of any then existing
lease affecting all or any portion of the First Negotiation Space as with the
existing tenant thereunder or its permitted assignee.

     5.   WARRANTY OF EXISTING CONDITION: Landlord shall provide the Premises
to Tenant with all electrical, plumbing, HVAC, elevator, fire safety system,
and roof systems in good working condition as of the Commencement Date.

     6.   COMMENCEMENT DATE: Landlord represents to Tenant, and Tenant
acknowledges, that (i) Landlord's existing lease with Altera Corporation
("Altera") for the Premises expires on July 4, 1997, (ii) that Altera has a
"hold-over" right to remain in the Premises for up to three (3) months after
the July 4, 1997 date, and (iii) Altera must exercise its "hold-over" right
and state the length

<PAGE>

Page Three


of the hold-over period no later than February 1, 1997.  Therefore, the
Commencement Date of August 3, 1997 of this Lease shall be delayed for up to
three (3) months beyond August 3, 1997 (i) only if Landlord provides written
notice to Tenant that Altera has exercised its "hold-over" right, and (ii)
the Commencement Date of this Lease shall be delayed a period equal to
Landlord's written notice to Tenant stating the period of time of Altera's
hold-over, which notice shall be delivered to Tenant no later than February
15, 1997.  If Altera does not deliver possession of the Premises to Landlord
on or before the date Altera is required to surrender, whether such date is
July 4, 1997, or an extended date set by a hold-over notice, then the
Commencement Date shall be delayed one day for every day beyond such required
surrender date, during which Altera continues in possession of the Premises.
Although the Commencement Date shall not be affected by the date of
Substantial Completion of Interior Improvements under Exhibit "B" hereto,
Landlord agrees that it will keep Tenant advised on negotiations for the
construction contract with the Prime Contractor, that it will provide in such
contract for penalties for delay in completion of construction by the Prime
Contractor, and that Tenant will have the right to approve the Prime
Construction Contract, approval not be unreasonably withheld or delayed,
solely with regard to the timeline schedule for construction, the penalties
which are to be charged to the Prime Contractor in the event of delay, and
construction warranties.

without change Tenant as part of its Allocated Parking Stalls shall have the
exclusive use of not more than fifteen (15) reserved parking spaces, at the

the parking area designated for Tenant's exclusive use.

     8.   RULES AND REGULATION: Notwithstanding anything to the contrary in
the Lease, Tenant shall not be required to comply with any new rule or
regulation enacted solely by Landlord, unless the same applies
nondiscriminatory to all occupants of the Project and does not unreasonably
interfere with Tenant's use of the Premises, the Common Area, or Tenant's
parking rights.

     9.   ALTERATIONS, ADDITIONS AND IMPROVEMENTS: Notwithstanding anything
to the contrary in the Lease Form:

          A.   LANDLORD'S CONSENT: If Landlord's consent is required for a

Premises at Tenant's expense.  Tenant may remove Tenant's Property from the

greater of (i) one hundred percent (100%) of the Base Monthly Rent due the
last month of the previous Lease Term, or (ii) one-hundred percent (100%) of
the then fair market monthly rent determined as of the commencement of the
option period in question based upon like buildings with like improvements in
the San Jose area within the boundaries of Highways 237,101 and 880.  If the
parties are unable to agree upon the fair market monthly rent for the
Premises for the option period in question at least seventy-five (75) days
prior to the commencement of the option period in question, then the fair
market monthly rent shall be determined by appraisal conducted pursuant to
subparagraph E.

          E.   In the event it becomes necessary to determine by appraisal
the fair market rent of the Premises for the purpose of establishing the Base
Monthly Rent during the Option Period, then such fair market monthly rent
shall be determined by three (3) real estate appraisers, all of whom shall be
members of the American Institute of Real Estate Appraisers with not less
than five (5) years experience appraising real property (other than
residential or agricultural property) located in Santa Clara County,
California, in accordance with the following procedures:

               (1)  The party demanding an appraisal (the "Notifying Party")
shall notify the other party (the "Non-Notifying Party") thereof by
delivering a written demand for appraisal, which demand, to be effective,
must give the name, address, and qualifications of an appraiser selected by
the Notifying Party. Within ten (10) days of receipt of said demand, the
Non-Notifying Party shall select its appraiser and notify the Notifying
Party, in writing, of the name, address, and qualifications of an appraiser
selected by it.  Failure by the Non-Notifying Party to select a qualified
appraiser within said ten (10) day period shall be deemed a waiver of its
right to select a second appraiser on its own behalf and the Notifying Party
shall select a second appraiser on behalf of the Non-Notifying Party within
five (5) days after the expiration of said ten (10) day period.  Within ten
(10) days from the date the second appraiser shall have been appointed, the
two (2) appraisers so selected shall appoint a third appraiser.  If the two
appraisers fail to select a third qualified appraiser, the third appraiser
shall be selected by the American Arbitrations Association or if it shall
refuse to perform this function, then at the request of either Landlord or
Tenant, such third appraiser shall be promptly appointed by the then
Presiding Judge of the Superior Court of the State of California for the
County of Santa Clara.

               (2)  The three (3) appraisers so selected shall meet in San
Jose, California, not later than twenty (20) days following the selection of
the third appraiser.  At said meeting the appraisers so selected shall
attempt to determine the fair market monthly rent of the Premises for the
option period in question (including the timing and amount of periodic
increases).

               (3)  If the appraisers so selected are unable to complete
their determinations in one meeting, they may continue to consult at such
times as they deem necessary for a fifteen (15) day period from the date of
the first meeting, in an attempt to have at least two (2) of them agree.  If,
at the initial meeting or at any time during said fifteen (15) day period,
two (2) or more of the appraisers so selected agree on the

<PAGE>

fair market rent of the Leased Premises, such agreement shall be
determinative and binding on the parties hereto, and the agreeing appraisers
shall, in simple letter form executed by the agreeing appraisers, forthwith
notify both Landlord and Tenant of the amount set by such agreement.

<PAGE>

Page Six


               (4)  If two (2) or more appraisers do not so agree within said
fifteen (15) day period, then each appraiser shall, within five (5) days
after the expiration of said fifteen (15) day period, submit his independent
appraisal in simple letter form to Landlord and Tenant stating his
determination of the fair market rent of the Premises for the option period
in question.  The parties shall then determine the fair market rent for the
Premises by determining the average of the fair market rent set by each of
the appraisers.  However, if the lowest appraisal is less than eighty-five
percent (85%) of the middle appraisal then such lowest appraisal shall be
disregarded and/or if the highest appraisal is greater than one hundred
fifteen percent (115%) of the middle appraisal then such highest appraisal
shall be disregarded.  If the fair market rent set by any appraisal is so
disregarded, then the average shall be determined by computing the average
set by the other appraisals that have not been disregarded.

               (5)  Nothing contained herein shall prevent Landlord and
Tenant from jointly selecting a single appraiser to determine the fair market
rent of the Premises, in which event the determination of such appraisal
shall be conclusively deemed the fair market rent of the Premises.

               (6)  Each party shall bear the fees and expenses of the
appraiser selected by or for it, and the fees and expenses of the third
appraiser (or the joint appraiser if one joint appraiser is used) shall be
borne fifty percent (50%) by Landlord and fifty percent (50%) by Tenant.

     17.  AMORTIZATION OF LARGE EXPENSES: Any expenses of repair or
replacement of a single item which are the responsibility of Landlord under
the Lease, which Landlord has the right to pass through to Tenant as Common
Operating Expenses or other form of Additional Rent, and which exceed, on any
single item, the sum of $50,000.00, shall be amortized over a time period to
be selected in Landlord's sole discretion, to be exercised in good faith, and
shall be charged to Tenant as Common Operating Expenses on such an amortized
basis.

     18.  EXTERIOR PLATE GLASS: Notwithstanding anything to the contrary in
the Lease, Landlord shall be solely responsible to pay any necessary and
reasonable expenses of replacement of any exterior plate glass which breaks
as a direct result of a structural defect in the Building.

     19.  FAILURE TO INSURE: If a loss is not covered by insurance due to a
party's failure to obtain such insurance in breach of said party's
obligations under this Lease, then the party which should have been insured
shall have the benefit of the above release notwithstanding the lack of
insurance, but solely to the extent that said party would have been released
had the party with the duty to insure performed that duty.

     20.  DAMAGE TO PREMISES: If, because of damage to the Premises, Landlord
has the right to terminate the Lease (a) under Paragraph 11.2A of this Lease,
or (b) under Paragraph II. 2D (I) of this Lease solely on the ground that the
cost of restoration are not reasonable within the meaning of said Paragraph
11.2D(I); then in either case Tenant shall have the option to avoid such
termination and have the Lease continue if Tenant fulfills the conditions set
forth in this Paragraph.  The option shall be exercised by written notice to
Landlord that Tenant will pay for all of the costs and expenses of said
restoration to the extent that same are not covered and paid by insurance.
Such notice must be given within ten (10) days after Landlord has given
Tenant notice of termination under such Paragraphs, and if such notice is not
given within the specified time, such option shall be of no further force or
effect.  If Tenant exercised such an option, then Landlord shall give Tenant
written notice of Landlord's estimate of (a) the costs and expenses of
restoration, and (b) the Landlord's anticipated insurance proceeds, if any.
Within thirty (30) days of Tenant's receipt of this notice, Tenant shall
deposit with

<PAGE>

Landlord the amount of the difference stated in Landlord's written estimate
between Landlord's insurance proceeds and the costs and expenses of
restoration.  If Tenant does not deposit such funds within the specified
time, then Landlord's notice of termination shall be deemed valid as
originally given, and Tenant's exercise of the option granted in this
Paragraph shall be null and void.  When the Premises have been rebuilt,
Landlord shall account to Tenant for the actual costs and expenses of
rebuilding and the actual insurance proceeds.  Within thirty (30) days of
Landlord's accounting, Tenant shall pay to Landlord any further sum necessary
to fully reimburse Landlord for the difference between its actually recovered
insurance proceeds and its actual costs of construction, or Landlord shall
reimburse the Tenant for any amount paid by Tenant in excess of the
difference between Landlord's actually recovered insurance proceeds and its
actual costs of construction, as the case may be

<PAGE>

     21.  QUIET POSSESSION: Tenant's right to quiet possession of the
Premises shall not be disturbed so long as Tenant is not in default and
performs all of its obligations under this Lease, unless this Lease is
otherwise terminated pursuant to its terms.

     22.  HAZARDOUS MATERIALS: No expenses of investigating, responding to,
or removing Hazardous Materials from the Property shall be recoverable by
Landlord from Tenant, as a Common Operating Expense or otherwise, if Tenant
shows by clear and convincing evidence that (a) the expenses were incurred as
a result of contamination caused solely by one of the other tenants of the
Property; or (b) the expenses were incurred because of contamination of the
Property which took place before the earlier of Tenant's first date of
occupancy of the Premises or the Commencement Date.  In the event of
contamination of the Property with Hazardous Materials which is not caused by
Tenant or its Agents, but as to which Tenant is not exculpated under (a) and
(b) above, Tenant shall be liable for all of the expenses for any
contamination, release, or spill which takes place within the Premises, but
Tenant shall be liable only for Tenant's Share of such expenses for such
contamination which takes place outside the Premises.

                           INTERIOR IMPROVEMENT AGREEMENT

     THIS IMPROVEMENT AGREEMENT is made part of that Lease dated December 6,
1996, (the "Lease") by and between SAN JOSE ACQUISITION CO., L.L.C.,
("Landlord"), and QUICKTURN DESIGN SYSTEMS, INC. ("Tenant").  Landlord and
Tenant agree that the following terms are part of the Lease:

     1.   PURPOSE OF IMPROVEMENT AGREEMENT: The purpose of this Improvement
Agreement is to set forth the rights and obligations of Landlord and Tenant
with respect to the construction of Interior Improvements within the Premises
prior to the Commencement Date.

     2.   DEFINITIONS: As used in this Interior Improvement Agreement, the
following terms shall have the following meanings, and terms which are not
defined below, but which are defined in the Lease and which are used in this
Interior Improvement Agreement, shall have the meanings ascribed to them by
the Lease:

          A.   APPROVED SPECIFICATIONS: The term "Approved Specifications"
shall mean those specifications for the Interior Improvements to be
constructed by Landlord which are described by Exhibit "C" to the Lease.

          B.   ARCHITECT: Design and Engineering Systems.

          C.   INTERIOR IMPROVEMENTS: The term "Interior Improvements" shall
mean all interior improvements to be constructed by Landlord in accordance
with the Approved Specifications (e.g., HVAC equipment and distribution,
transformer and power distribution, partitions, floor, wall, and window
covering, lighting fixtures), whether within or outside the exterior Premise
walls.

          D.   INTERIOR IMPROVEMENT COSTS: The term "Interior Improvement
Costs" shall mean the following: (i) the total amount due pursuant to the
general construction contract entered into by Landlord to construct the
Interior Improvements; (ii) the cost of all governmental approvals required
as a condition to the construction of the Interior Improvements (including
all construction taxes imposed by the City of San Jose) in connection with
the issuance of a building permit for the Interior Improvements; (iii) all
utility connection or use fees; (iv) fees of Architect or engineers for
services rendered in connection with the design and construction of the
Interior Improvements; and (v) the cost of payment and performance bonds
obtained by Landlord or Prime Contractor to assure completion of the Interior
Improvement. Notwithstanding the foregoing, in no event shall Interior
Improvement Costs include, and Landlord shall be solely responsible to pay:
(1) costs for which Landlord actually recovers from a third party (e.g.,
insurers, warrantors, tortfeasors), (2) cost for any work not shown on the
Final Interior Improvement Plans as the same may be modified by Change Orders
approved in writing by Tenant, or (3) construction management fees on that
portion of the Interior Improvement Costs paid out of any portion of the
Total Tenant Improvement Allowance.  However, Landlord may charge a
construction management fee, not to exceed 3%, on any Tenant contribution to
the payment of Interior Improvement Costs.  The parties acknowledge that the
City of San Jose imposes certain taxes as a condition to the issuance of
building permits in certain circumstances, including the "Building and
Structure Construction Tax" imposed by Chapter 4.46 of the City of San Jose
Municipal Code (the "BSC Tax") and the "Commercial-Residential-Mobile Home
Park Building Tax" imposed by Chapter 4.47 of the City of San Jose Municipal
Code (the "CRM Tax").  The parties further acknowledge that the rate for
these two taxes is higher for a structure designed or intended to be used for
"industrial purposes".  However, the parties acknowledge and agree that (i)
an

<PAGE>

additional BSC Tax will be due upon the issuance of a building permit for all
Interior Improvements if the City of San Jose determines that the Interior
Improvements are intended for "industrial purposes" or (ii) a BSC Tax and a
CRM Tax based on the value of the Interior Improvements, plus an additional
BSC Tax and a CRM Tax based on the value of the shell, will be due if the
City of San Jose determines that the Building is intended for "commercial
purposes", and (iii) any of such taxes that must be paid in order to obtain
building permits for the Interior Improvements shall be "Interior Improvement
Costs".

          E.   SUBSTANTIAL COMPLETION AND SUBSTANTIALLY COMPLETE: The terms
"Substantial Completion" and "Substantially Complete" shall each mean the
date when all the



                                      EXHIBIT B
<PAGE>

Page Two


following have occurred with respect to the Interior Improvements in
question: (i) the construction of the Interior Improvements in question has
been substantially completed in accordance with the requirements of this
Lease, except for Punchlist items which do not unreasonably interfere with
Tenant's use of the Premises for Tenant's intended purpose; (ii) the
Architect responsible for preparing the plans shall have executed a
certificate or statement representing that the Interior Improvements in
question have been substantially completed in accordance with the plans and
specifications therefor; and (iii) the Building Department of the City of San
Jose or any other approvals required by applicable Law has completed its
final inspection of such improvements and has "signed off' the building
inspection card approving such work as complete.

     3.   SCHEDULE OF PERFORMANCE: Set forth in this paragraph is a schedule
of certain critical dates relating to Landlord's and Tenant's respective
obligations regarding the construction of the Interior Improvements (the
"Schedule of Performance").  Landlord and Tenant shall each be obligated to

Interior Improvement Agreement.  The Schedule of Performance is as follows:

                         improvements or long lead items.

     4.   CONSTRUCTION OF INTERIOR IMPROVEMENTS: Landlord shall construct the
Interior Improvements in accordance with the following:

          A.   DEVELOPMENT AND APPROVAL OF PRELIMINARY INTERIOR PLANS: On or
before the due date specified in the Schedule of Performance, Tenant shall
deliver to Landlord a proposed floor plan identifying its requirements for
the Interior Improvements that is consistent with the Approved Specifications
("Tenant's Interior Requirements").  On or before the due date specified in
the Schedule of Performance, Landlord shall and deliver to Tenant for its
review and approval preliminary plans for the Interior Improvements which are
consistent with and conform to Tenant's Interior Requirements and the
Approved Specifications (the "Preliminary Interior Plans").  On or before the
due date specified in the Schedule of Performance, Tenant shall either
approve such plans or notify Landlord in writing of its specific objections
to the Preliminary Interior Plans.  If Tenant so objects, Landlord shall
revise the Preliminary Interior Plans to address such objections in a manner
consistent with the parameters for the Interior Improvements set forth in
this Improvement Agreement and the Approved Specifications and shall resubmit
such revised Preliminary Interior Plans as soon as reasonably practicable to
Tenant for its approval. When such revised Preliminary Interior Plans are
resubmitted to Tenant, it shall either approve such plans or notify Landlord
of any further objections in writing within two (2) business days after
receipt thereof.  If Tenant has further objections to the revised Preliminary
Interior Plans, the parties shall meet and confer to develop Preliminary
Interior Plans that are acceptable to both Landlord and Tenant within five
(5) business days after Tenant has notified Landlord of its second set of
objections.  In the event Tenant and Landlord do not resolve all of Tenant's
objections within such five (5) business day period, Landlord and Tenant
shall immediately cause Landlord's Architect to meet and confer with Tenant's
architect or construction consultant, who shall apply the standards set forth
in this Improvement Agreement to resolve Tenant's objections and incorporate
such resolution into the Preliminary Interior Plans, which process Landlord
and Tenant shall cause to be completed within five (5) business days after
the conclusion of the five (5) business day period referred to in the
immediately preceding sentence.

          B.   DEVELOPMENT AND APPROVAL OF FINAL INTERIOR PLANS: Once the
Preliminary Interior Plans have been approved by Landlord and Tenant
(including all changes made to resolve Tenant's objections approved by
Landlord's Architect and Tenant's representative or construction consultant
pursuant to subparagraph 4A), Landlord shall complete and submit to Tenant
for its approval final working drawings for the Interior Improvements by the
due date specified in the Schedule of Performance.  Tenant shall approve the
final plans for the Interior Improvements or notify Landlord in writing of
its specific objections by the due date specified in the Schedule of
Performance.  If Tenant so objects, the parties shall confer and reach
agreement upon final working drawings for the Interior Improvements within
five (5) business days after Tenant has notified Landlord of its objections.
In the event Tenant and Landlord do not resolve all of Tenant's objections
within such five (5) business day period, Landlord and Tenant shall
immediately cause the Architect to meet and confer with Tenant's
representative or construction consultant, who shall apply the standards set
forth in the Improvement Agreement to resolve Tenant's objections and
incorporate such resolution into the Final Interior Plans, which process
Landlord and Tenant shall cause to be completed within five (5) business days
after the conclusion of the five (5) business day period referred to in the
immediately preceding sentence.  The final working drawings so approved by
Landlord and Tenant (including all changes made to resolve Tenant's
objections approved by the Architect and Tenant's representative or
construction consultant) are referred to herein

<PAGE>

as the "Final Interior Plans".

          C.   STANDARD FOR CONSENT: Landlord's and Tenant's approval of the
Tenant Interior Requirements, the Preliminary Interior Plans, the Final
Interior Plans, the Final Improvement Cost Budget, and any modifications
thereto or to the Schedule of Performance shall not be unreasonably withheld
or delayed, provided, however, that:

<PAGE>

Page Four


               1.   Landlord may withhold its approval in its sole discretion
to any work, which adversely affects the building structure, roof or building
service equipment, is visible from the exterior of the premises and is not
aesthetically in keeping with the Project, and

               2.   Tenant may withhold is approval in its sole discretion to
any work, which causes the Final Improvement Cost Budget to exceed the Total
Landlord's Allowance by more than $50,000.00, delays the expected Substantial
Completion Date more than 60 days, or modifies the Interior Improvements
within the demising wall of the Premises.

Any disapproval by Landlord or Tenant shall be accompanied by a written
statement of the disapproved item, the reasons for disapproval, and the
specific changes required to make the item acceptable.  If a party's written
notice of disapproval is not delivered in accordance with the time limits and
standards set forth in this Agreement, such disapproval shall be deemed not
given.

          D.   BUILDING PERMIT: As soon as the Final Interior Plans have been
approved by Landlord and Tenant, Landlord shall apply for a building permit
for the Interior Improvements, and shall diligently prosecute to completion
such approval process.

          E.   CONSTRUCTION CONTRACT: Landlord and Tenant shall cooperate to
cause the Interior Improvements to be constructed by a general contractor who
is engaged by Landlord in accordance with the procedures set forth in
subparagraph 4D(1) hereof.

               (1)  The job of constructing the Interior Improvements shall
be offered for "competitive bid", on a fixed price basis, to three (3)
general contractors selected by Landlord and approved by Tenant.  The
construction contract in form reasonably acceptable to Tenant shall be
awarded to the bidder submitting the lowest bid for the job.  Landlord shall
submit to Tenant a list of general contractors acceptable to Landlord to whom
the job may be bid, and Tenant shall notify Landlord within three (3)
business days after receipt of such list of its objection to any proposed
contractor.  Tenant's failure to object within such period of time shall be
deemed to be its approval of all bidders on the list so submitted by
Landlord.  If the lowest bid resulting from such competitive bidding process
indicates that the Interior Improvement Costs will exceed $1,020,705.00
Dollars ($7.00 per gross leasable square foot of the Premises), Landlord
shall promptly notify Tenant, in writing, to that effect, and Tenant shall
have the right to propose modifications to the Final Interior Plans within
five (5) business days after Tenant's receipt of Landlord's notice, subject
to Landlord's approval of such changes, for the purpose of reducing the
Interior Improvement Costs.  Such revision of the final Interior Plans shall
be completed as expeditiously as possible; provided, however, that (i) the
job shall nonetheless be awarded to the low bidder whose price shall be
adjusted based upon the changes requested by Tenant and approved by Landlord
made to the Final Interior Plans; and (ii) if Tenant should choose to
exercise its right to modify the final Interior Plans for the purpose of
reducing the Interior Improvement costs, any delay resulting from the failure
by Tenant to timely exercise its right to do so shall be a delay caused by
Tenant for purposes of paragraph 7 hereof.

               (2)  Landlord and Tenant shall use their best efforts to
approve the general contractor and all subcontractors all major material
suppliers and the form of contract for such parties so that the construction
contract may be executed as soon as possible.

          F.   COMMENCEMENT OF INTERIOR IMPROVEMENTS: On or before the due
date specified in the Schedule of Performance, Landlord shall commence
construction for the Interior Improvements and shall diligently prosecute
such construction to completion, using all reasonable efforts to achieve
Substantial Completion of the Interior

<PAGE>

Improvements by the due date specified in the Schedule of Performance.

     5.   PAYMENT OF INTERIOR IMPROVEMENT COSTS: Landlord and Tenant shall
have the following obligations with respect to the payment of Interior
Improvement Costs:

          A.   Landlord shall be obligated to pay an amount equal to the
Tenant Improvement Allowance (including the First Level Tenant Improvement
Allowance and so much of the Second Level Tenant Improvement Allowance as
Tenant shall elect to utilize) as provided for in Paragraph 1 of the First
Addendum To Lease for the Payment of Interior Improvement costs.  If the
total of Interior Improvement Costs exceeds the amount of Landlord's
required

<PAGE>

Page Five


contribution, Tenant shall be obligated to pay the entire amount of such
excess either in cash or, if the Second Level Tenant Improvement Allowance
has not been depleted, from such portion of the Second Level Tenant
Improvement Allowance as Tenant shall elect to utilize.  In the event that
Tenant elects to utilize all or a portion of the Second Level Tenant
Improvement Allowance for these purposes, then the Base Monthly Rent shall be
increased as provided for in Paragraph 2 of the First Addendum to Lease.  In
no event shall Landlord be obligated to pay for Interior Improvement Costs in
excess of the allowances provided for in Paragraph 1 of the First Addendum To
Lease.  If Tenant becomes obligated to contribute toward paying Interior
Improvement Costs pursuant to this subparagraph 5A, then Landlord shall
estimate the amount of such excess prior to commencing construction of the
Interior Improvements and Tenant shall pay to Landlord a proportionate share
of each progress payment due to the general contractor which bears the same
relationship to the total amount of the progress payment in question as the
amount Tenant is obligated to contribute to the payment of Interior
Improvement Costs bears to the total estimated Interior Improvement Costs
approved by Tenant at the time the final Improvement Plans are approved.
Tenant shall pay Tenant's share of any progress payment to Landlord within
five (5) business days after receipt of a statement therefor from landlord.
At the time the final accounting is rendered by Landlord pursuant to
subparagraph 5C hereof, there shall be an adjustment between Landlord and
Tenant such that each shall only be required to contribute to the payment of
Interior Improvement Costs in accordance with the obligations set forth in
this subparagraph 5A, which adjustment shall be made within five (5) days
after Landlord notifies Tenant of the required adjustment.  If Tenant is
required to make a payment to Landlord, Tenant shall make such payment even
if Tenant elects to audit the statement submitted by Landlord pursuant to
subparagraph 5C.  In the event Tenant's audit discloses that an overpayment
or underpayment was made by Tenant, there shall be an adjustment between
Landlord and Tenant as soon as reasonably practicable such that each shall
only be required to contribute to the payment of costs in accordance with the
obligations set forth in this subparagraph 5A.

          B.   If Tenant fails to pay any amount when due pursuant to this
paragraph 5, then (i) Landlord may (but without the obligation to do so)
advance such funds on Tenant's behalf, and Tenant shall be obligated to
reimburse Landlord for the amount of funds so advanced on its behalf, and
(ii) Tenant shall be liable for the payment of a late charge and interest in
the same manner as if Tenant had failed to pay Base Monthly Rent when due as
described in paragraph 3.4 of the Lease.  Any amounts paid to Landlord by
Tenant pursuant to this subparagraph shall be held by Landlord as Tenant's
agent, for disbursal to the general contractor in payment for work costing in
excess of Landlord's required contribution.

          C.   When the Interior Improvements are Substantially Completed,
Landlord shall submit to Tenant a final and detailed accounting of all
Interior Improvement Costs paid by Landlord, certified as true and correct by
Landlord's financial officers.  Tenant shall have the right to audit the
books, records, and supporting documents of Landlord to the extent necessary
to determine the accuracy of such accounting during normal business hours
after giving Landlord at least two (2) days prior written notice.  Tenant
shall bear the cost of such audit, unless such audit discloses that Landlord
has overstated the total of such costs by more than two percent (2%) of the
actual amount of such costs, in which event Landlord shall pay the cost of
Tenant's audit.  Any such audit must be conducted, if at all, within ninety
(90) days after Landlord delivers such accounting to Tenant.

     6.   CHANGES TO APPROVED PLANS: Once the Final Interior Plans have been
approved by Landlord and Tenant, neither shall have the right to order extra
work or change orders with respect to the construction of the Interior
Improvements without the prior written consent of the other which consent
shall be given or withheld in accordance with Section 4.C above.  All extra
work or change orders requested by either Landlord or Tenant shall be made in
writing, shall specify any added or reduced cost and/or construction time
resulting therefrom, and shall become effective and a part of the Final
Interior Plans

<PAGE>

once approved in writing by both parties.  If a change order requested by
Tenant results in an increase in the cost of constructing the Interior
Improvements, Tenant shall pay the amount of such increase caused by the
change order requested by Tenant at the time the change order is approved by
both Landlord and Tenant if and to the extent such change order causes the
Interior Improvement Costs to exceed Landlord's required contribution thereto
described in subparagraph 5A.  If a change order results in an

<PAGE>

Page Six


increase in the amount of construction time needed by Landlord to complete
the Interior Improvements, paragraph 7 hereof may apply.

     7.   DELIVERY OF POSSESSION AND PUNCH LIST AGREEMENT: As soon as the
Interior Improvements are Substantially Completed, Landlord and Tenant shall
together walk through the Premises and inspect all Interior Improvements so
completed, using reasonable efforts to discover all uncompleted or defective
construction in the Interior Improvements.  After such inspection has been
completed, each party shall sign an punch list agreement in the form attached
to the Lease as EXHIBIT "D", which shall include a list of all "punch list"
items which the parties agree are to be corrected by Landlord.  As soon as
such inspection has been completed and such agreement executed, Landlord
shall use reasonable efforts to complete and/or repair such "punch list"
items within thirty (30) days after executing the punch list agreement.
Tenant's taking possession of any part of the Premises shall be deemed to be
an acceptance by Tenant of Landlord's work of improvement in such part as
complete and in accordance with the terms of the Lease except for the punch
list items noted and latent defects that could not reasonable have been
discovered by Tenant during its inspection of the Interior Improvements prior
to completion of the punch list agreement.  Notwithstanding anything
contained herein, Tenant's obligation to pay the Base Monthly Rent and
Additional Rent shall commence as provided in the Lease, regardless of
whether Tenant completes such inspection or executes such punch list
agreement.

     8.   STANDARD OF CONSTRUCTION AND WARRANTY:  Landlord hereby warrants
that the Interior Improvements shall be constructed in accordance with the
Final Interior Plans (as modified by change orders approved by Landlord and
Tenant), all Private Restrictions and all Laws, in a good and workmanlike
manner, and all materials and equipment furnished shall conform to such final
plans and shall be new and otherwise of good quality.  The foregoing warranty
shall be subject to, and limited by, the following:

          A.   Once Landlord is notified in writing of any breach of the
above-described warranty, Landlord shall promptly commence the cure of such
breach and complete such cure with diligence at Landlord's sole cost and
expense.

          B.   Landlord's liability pursuant to such warranty shall be
limited to the cost of correcting the defect or other matter in question.  In
no event shall Landlord be liable to Tenant for any damages or liability
incurred by Tenant as a result of such defect or other matter, including
without limitation damages resulting from any loss of business by Tenant or
other consequential damages, provided Landlord promptly commences and
diligently completes the cure of the breach of warranty after the delivery of
written notice of the need for cure to Landlord.

          C.   Notwithstanding anything contained herein, Landlord shall not
be liable for any defect in design, construction, or equipment furnished
which is discovered and of which Landlord receives written notice from Tenant
after the first (1st) anniversary of the recordation of a notice of
completion for the work of improvement affected by the defect.

          D.   With respect to defects for which Landlord is not responsible
pursuant to this Lease or with respect to repairs for which Landlord is
responsible hereunder, but which Landlord fails to complete within thirty
(30) days (or such longer time as is reasonably required to complete the
repair) following delivery to Landlord of notice of the need for repairs,
Tenant shall have the benefit of any construction or equipment warranties
existing in favor of Landlord that would assist Tenant in correcting such
defect and in discharging its obligations regarding the repair and
maintenance of the Premises.  Upon request by Tenant, Landlord shall inform
Tenant of all written construction and equipment warranties existing in favor
of Landlord which affect the Interior Improvements.  Landlord shall cooperate
with Tenant in enforcing such warranties

<PAGE>

and in bringing any suit that may be necessary to enforce liability with
regard to any defect for which Landlord is not responsible pursuant to this
paragraph so long as Tenant pays all costs reasonably incurred by Landlord in
so acting.

          E.   Landlord makes no other express or implied warranty with
respect to the design, construction or operation of the Interior Improvements
except as set that forth in this Lease.

anything to the contrary in the Lease or this Improvement Agreement, Tenant's
acceptance of the Interior Improvements shall not waive the foregoing
warranty.

     9.   EFFECT OF AGREEMENT: In the event of any inconsistency between this
Improvement Agreement and the Lease, the terms of this Improvement Agreement
shall prevail.

or recording such release together with the payment of such other costs,
interest or fees as shall have been incurred.

("Approving Agent").

                                  R E C I T A L S:

     WHEREAS, New England Mutual Life Insurance Company, a Massachusetts

in Book E104, Page 74 of the Official Records of Santa Clara County; and

     WHEREAS, Orchard Properties is the Approving Agent under the CC&Rs and
desires to enact this First Amendment to First Sign Criteria in order (i) to

minimum requirements only and that so long as there exists an Approving Agent,
as defined in the CC&Rs, then prior to installation or replacement of any sign
upon any lot(s) in the Orchard Technology Park, the then serving Approving Agent
must approve a sign plan related thereto, as more specifically provided in the
CC&Rs.

     NOW, THEREFORE, the Approving Agent herein enacts this First Amendment to

                              AND ATTORNMENT AGREEMENT


     THIS AGREEMENT is entered into as of the _________ day of ______ , ______,
by and between _____________, a__________________(the "Beneficiary"),
____________________, __________________(the "Tenant") and ______________,
a _______________(the "Landlord").



                                     WITNESSETH

     A.   Tenant has entered into a certain lease dated __________, ______, (the
"Lease") with Landlord covering certain space (the "Premises") located in and
upon the real property described in Schedule 1 attached hereto (the "Property");

     B.   Beneficiary is the holder of a mortgage loan (the "Loan") to Landlord
in the amount of_____________ Dollars ($___________________) which is secured by
a_______________________________(the "Deed of Trust") covering the Property;

     C.   The parties hereto desire expressly to confirm the subordination of
the Lease to the lien of the Deed of Trust, it being a requirement by
Beneficiary that the lien and charge of the Deed of Trust be unconditionally and
at all times prior and superior to the leasehold interests and estates created
by the Lease; and

     D.   Tenant has requested that Beneficiary agree not to disturb Tenant's
possessory rights in the Premises in the event Beneficiary should foreclose the
Deed of Trust, provided that Tenant is now in default under the Lease and
provided that Tenant attorns to Beneficiary or the purchaser at any foreclosure
or Trustee's sale of the Property.

     NOW, THEREFORE, in consideration of the mutual covenants contained herein
and of other good and valuable consideration the receipt and sufficiency of
which is hereby acknowledged, the parties hereby agree as follows:

     1.   Notwithstanding anything to the contrary set forth in the Lease, the
Lease and the leasehold estate created thereby and all of Tenant's rights
thereunder shall be and shall at all times remain subject, subordinate to the
Deed of Trust and the lien thereof and all rights of Beneficiary thereunder and
to any and all renewals, modifications, consolidations, replacements and
extensions thereof.

     2.   Tenant hereby declares, agrees and acknowledges that:

          A.   Beneficiary would not have agreed to recognize the Lease without
this Agreement; and

          B.   Beneficiary, in making disbursements pursuant to the agreements
evidencing and securing the Loan, is under no obligation or duty to oversee or
direct the application of the proceeds of such disbursements and such proceeds
may be used by Landlord for purposes other than improvement of the Premises.

     3.   In the event of foreclosure of the Deed of Trust, or upon a sale of
the Property pursuant to the Trustee's power of sale contained therein, or upon
a transfer of the Property by deed in lieu of foreclosure, then so long as
Tenant is not in default under any of the terms, covenants, or conditions of the
Lease, the Lease shall continue in full force and effect as a direct lose
between the succeeding owner of the Property and Tenant, upon and subject to all
of the terms, covenants and conditions of the Lease for the balance of the term
of the Lease.  Tenant hereby agrees to attorn to and accept any such successor
owner as landlord under the Lease, and to be bound by and perform all of the
obligations imposed by the Lease, and Beneficiary or any such successor owner of


<PAGE>
the Property will not disturb the possession of Tenant, and will be bound by all
of the obligations imposed by the Lease upon the landlord thereunder:  provided,
however, that the Beneficiary, or any purchaser at a trustee's or sheriff's sale
or any successor owner of the Property shall not be:

          A.  liable for any act or omission of a prior landlord (including
Landlord); or

          B.  subject to any offsets or defenses which the Tenant might have
against any prior landlord (including Landlord); or


                                      EXHIBIT G
<PAGE>
          C.  bound by any rent or additional rent which the Tenant might have
paid in advance to any prior landlord (including Landlord) for a period in
excess of one month; or

          D.  bound by any agreement or modification of the Lease made without
the written consent of the Beneficiary; or

          E.  liable or responsible for or with respect to the retention,
application and/or return to Tenant of any security deposit paid to any prior
lessor (including Landlord), whether or not still held by such prior lessor,
unless and until Beneficiary or such other purchaser has actually received for
its own account as lessor the full amount of such security deposit; or

          F.  bound by or liable under any representations, warranties,
covenants or indemnities made to Tenant by any prior landlord (including
Landlord) regarding Hazardous Materials (as defined in the Lease); or

          G.  obligated to construct the building in which the Premises are
located or any improvements for Tenant's use.

     4.   Upon the written request of Beneficiary at the time of a
foreclosure, Trustee's sale or deed in lieu thereof or at any time
thereafter, the parties agree to execute a lease of the Premises upon the
same terms and conditions as the Lease between Landlord and Tenant, which
lease shall cover any unexpired term of the Lease existing prior to such
foreclosure, Trustee's sale or conveyance in lieu of foreclosure.

     5.   Tenant agrees to give to Beneficiary, by registered mail, a copy of
any notice or statement served upon Landlord.  Tenant agrees not to exercise any
rights of termination available by virtue of a default unless (i) Landlord shall
have failed to cure such default, and (ii) following expiration of the
applicable period under the Lease for cure by Landlord of such default, Tenant
shall have furnished to Beneficiary notice of Landlord's failure to cure such
default and afforded Beneficiary an additional thirty (30) days following
receipt of such notice within which to cure such default or if such default
cannot be cured within that time, then such additional time as may be necessary
if within such thirty (30) days Beneficiary has commenced and is diligently
pursuing the remedies necessary to cure such default (including, but not limited
to, commencement of foreclosure proceedings if necessary to effect such cure),
in which event such right, if any, as Tenant might otherwise have to terminate
the Lease shall not be exercised while such remedies are being so diligently
pursued.

     6.   Landlord, as landlord under the Lease and trustor under the Deed of
Trust, agrees for itself and its heirs, successors and assigns, that: (i) this
Agreement does not constitute a waiver by Beneficiary of any of its rights under
the Deed of Trust, or in any way release Landlord from its obligation to comply
with the terms, provisions, conditions, covenants, agreements and clauses of the
Deed of Trust; and (ii) the provisions of the Deed of Trust remain in full force
and effect and must be complied with by Landlord, if Beneficiary so requires.

     7.   Tenant acknowledges that it has notice that the Lease and the rent and
all other sums due thereunder have been assigned or are to be assigned to
Beneficiary as security for the Loan secured by the Deed of Trust.  In the event
that Beneficiary notifies Tenant of a default under the Deed of Trust and
demands that Tenant pay its rent and all other sums due under the Lease to
Beneficiary, Tenant agrees that it will honor such demand and pay its rent and
all other sums due under the Lease directly to the Beneficiary or as otherwise
required pursuant to such notice.

     8.   All notices hereunder shall be deemed to have been duly given if
mailed by United States registered or certified mail, with return receipt
requested, postage prepaid, to Beneficiary at the following address (or at such
other address as shall be given in writing by Beneficiary to the Tenant) and
shall be deemed complete upon any such mailing:

all such obligations and liabilities shall be the responsibility of the party to

requirement in the Lease relating to the granting of a non-disturbance
agreement.
