1.   PREMISES.

     1.1  Premises. Landlord hereby leases to Tenant the Building and that
          --------
portion of the Lot (or all thereof if the Building constitutes the material
improvement thereon) upon which the same is situated (hereinafter collectively
referred to as the "Premises") as shown on Exhibit A attached hereto.
                                           ---------

     1.2  Reserved Rights. Landlord reserves the right to enter the Premises
          ---------------
upon reasonable notice to Tenant (except in case of an emergency) and/or to
undertake the following: inspect the Premises and/or the performance by Tenant
of the terms and conditions hereof; grant easements on the Project, dedicate for
public use portions thereof and record covenants, conditions and restrictions
("CC&R's") affecting the Project and/or amendments to existing CC&R's which do
not unreasonably interfere with Tenant's use of the Premises; change the name of
the Project; and, during the last nine (9) months of the Term, show the Premises
to prospective tenants.

2.   TERM.
     ----

     2.1  Lease Term and Commencement Date. The Term of the Lease shall be for a
          --------------------------------
period of sixty (60) months, subject to extension in accordance with Section 20
below. The Term shall commence (the "Commencement Date") on the first day of the
first full calendar month following the Possession Date (as defined in Section
2.2.2), except that if the Possession Date occurs on the first day of a month,
that day shall also be the Commencement Date. Tenant shall execute and deliver
to Landlord, upon request by Landlord, a Commencement Date Memorandum in the
form attached hereto as Exhibit C acknowledging (i) the Commencement Date (and,
                        ---------
if requested, the Possession Date and Rent Commencement Date, as defined below),
(ii) the final square footage of the Premises, and (iii) Tenant's acceptance of
the Premises.

     2.2  Possession.
          ----------

          2.2.1  Landlord's Possession. Tenant acknowledges that the Premises
                 ---------------------
are currently occupied by an existing tenant thereof and that Landlord's
delivery of possession of the Premises is contingent upon such tenant vacating
the Premises. Landlord presently anticipates that the current tenant will vacate
the Premises and restore possession thereof to Landlord on or about September 1
1996 and Landlord shall use its commercially reasonable efforts to recover
possession on such date or as soon as practicable thereafter. In the event that
Landlord does not recover possession of the Premises on or before such date, as
a result of the failure of the existing tenant to vacate the Premises on or
before such date, Landlord shall not be subject to any liability therefor and
such failure shall not affect the validity of this Lease or the obligations of
either party hereunder, provided, however, that if the existing tenant fails to
vacate the Premises on or before November 1, 1996 (subject to Force Majeure
events), either Landlord or Tenant may, at its option, by written notice to the
other party given within ten (10) days thereafter, terminate this Lease, in
which event Landlord shall return to Tenant all funds paid in advance and the
Parties shall be discharged from all further obligations hereunder.
Notwithstanding anything set forth in this Section 2.2, Tenant shall not be
obligated to pay Base Rent for its use and occupancy of the Premises until the
Rent Commencement Date, as defined in Section 3.1.

          2.2.2  Tender of Possession to Tenant. Landlord shall tender
                 ------------------------------
possession of the Premises to Tenant as soon as practicable following the date
on which Landlord receives possession thereof. Tenant's possession and use of
the Premises from the date on which Landlord tenders possession thereof to
Tenant (the "Possession Date") to the Commencement Date (the "Early Possession
Period") shall be subject to all the provisions of this Lease. During the Early
Possession Period, Tenant shall (i) arrange for and pay for all utilities
delivered to the Premises (ii) arrange for, and maintain in effect, the
insurance coverages required to be obtained by Tenant pursuant to Section 7.2
of this Lease, (iii) pay to Landlord as and when due, all sums payable to
Landlord hereunder, including, without limitation. amounts payable for Real
Property Taxes (as defined in Section 5) and insurance premiums, and (iv)
perform all other obligations required by Tenant pursuant to this Lease.

          2.2.3  Tenant Improvements. Landlord shall arrange for the
                 -------------------
construction of certain Tenant improvements (as defined in the Work Letter
attached hereto as Exhibit B) in accordance with and subject to the terms of the
                   ---------
Work Letter. Landlord shall commence the construction of the Tenant improvements
and diligently pursue such construction to completion as soon as reasonably
practicable following the Possession Date. Tenant's use of the Premises shall
not unreasonably interfere with Landlord's contractor(s) or otherwise impede the
completion of the Tenant Improvements. The construction of the Tenant
improvements shall not delay the occurrence of the Commencement Date. Tenant has
determined that the Premises are acceptable for Tenant's use and Tenant
acknowledges that, except as set forth in the Work Letter, neither Landlord nor
any broker or agent has made any representations or warranties in connection
with the physical condition of the Premises or their fitness for Tenant's use
upon which Tenant has relied directly or indirectly for any purpose.

          2.2.4  Substantial Completion. The Tenant improvements shall be
                 ----------------------
deemed to be "Substantially Complete" on the date on which Landlord files or
causes to be filed with the City in which the Premises are located (if required)
and

                                      1.
<PAGE>
 
delivers to Tenant an architect's notice of substantial completion, or similar
written notice that the Tenant Improvements are Substantially Complete. As used
herein, the term "Substantially Complete" means that the Tenant Improvements
have been constructed in substantial compliance with the applicable plans and
specifications, except only minor "punchlist" items. Landlord shall promptly
complete such punchlist items to the reasonable satisfaction of Tenant.

3.   RENT.
     ----

     3.1  Rent.
          ---- 

          3.1.1  Tenant's obligation to pay Base Rent shall commence on the
first (1st) calendar day following the date on which the Tenant Improvements are
Substantially Complete and possession of the Premises has been tendered to
Tenant (the "Rent Commencement Date"). Tenant shall pay to Landlord, at
Landlord's Address for Payment of Rent designated in the Basic Lease
Information, or at such other address as Landlord may from time to time
designate in writing to Tenant for the payment of Rent, the Base Rent, without
notice, demand, offset or deduction, in advance, on the first day of each
calendar month. Upon the execution of this Lease, Tenant shall pay to Landlord
the first month's Base Rent. Base Rent for the period from the Rent Commencement
Date to the first day of the next calendar month shall be prorated on a per diem
basis. All sums other than Base Rent which Tenant is obligated to pay under this
Lease shall be deemed to be additional rent due hereunder, whether or not such
sums are designated "additional rent." The term "Rent" means the Base Rent and
all additional rent payable hereunder.

          3.1.2  As set forth in the Basic Lease Information, the initial Base
Rent shall be the sum of $74,800.00 per month which is calculated on the basis
of $0.34 per square foot. Tenant acknowledges that the Premises contains
approximately 220,000 rentable square feet of space. The parties acknowledge
that such measurement is an estimate and that the Base Rent shall not be
adjusted on the basis of a difference in the actual number of rentable square
feet.

     3.2  Late Charge and Interest. The late payment of any Rent will cause
          ------------------------
Landlord to incur additional costs, including administration and collection
costs and processing and accounting expenses and increased debt service
("Delinquency Costs"). If Landlord has not received any installment of Rent
within ten (l0) days after such amount is due, Tenant shall pay a late charge
of five percent (5%) of the delinquent amount, which is agreed to represent a
reasonable estimate of the Delinquency Costs incurred by Landlord. In addition,
all such delinquent amounts shall bear interest from the date such amount was
due until paid in full at a rate per annum ("Applicable Interest Rate") equal to
the lesser of (a) the maximum interest rate permitted by law or (b) five percent
(5%) above the rate publicly announced by Bank of America, N.A. (or if Bank of
America, N.A. ceases to exist, the largest bank then headquartered in the State
of California ("Bank") as its "Reference Rate." If the use of the announced
Reference Rate is discontinued by the Bank, then the term Reference Rate shall
mean the announced rate charged by the Bank which is, from time to time,
substituted for the Reference Rate. Landlord and Tenant recognize that the
damage which Landlord shall suffer as a result of Tenant's failure to pay such
amounts is difficult to ascertain and said late charge and interest are the best
estimate of the damage which Landlord shall suffer in the event of late payment
If a late charge becomes payable for any three (3) installments of Rent within
any twelve (l2) month period, then the Rent shall automatically become due and
payable quarterly in advance.

     3.3  Intentionally Omitted.
          ---------------------

4.   UTILITIES. Tenant shall make all arrangements for and shall pay all charges
     ---------
for heat, water, gas, electricity, telephone and any other utilities used on or
provided to the Premises including, without limitation, paying any deposits and
"hook up charges." Landlord shall not be liable to Tenant for interruption in or
curtailment of any utility service, nor shall any such interruption or
curtailment constitute constructive eviction or grounds for rental abatement.
The cost of maintaining and repairing the plumbing, electrical distribution, and
mechanical systems, and other utility installations shall be borne by the
parties as provided in Section 8.

5.   TAXES.

the method of invoicing Tenant for Real Property Taxes more than one (1) time
in each three (3) year period and, in each case, shall give Tenant thirty (30)
days notice prior to any change in such method of invoicing Tenant. In addition,
Landlord may elect to collect such Real Property Taxes from Tenant in advance,
on a monthly or quarterly basis, based upon Landlord's reasonable estimate of
such Real Property Taxes. If the amount of monthly or quarterly payments for
estimated Real Property Taxes received by Landlord from Tenant is more or less
than the actual Real Property Taxes due, an appropriate adjustment shall be made
by Landlord and Tenant.

          5.1.2  Partial Years. Real Property Taxes for partial tax fiscal

                   -----------------

(90) days, this Lease shall not terminate and, provided that insurance proceeds
are available to fully repair the damage. Landlord shall repair the Premises
utilizing such insurance proceeds and shall not recover any of such repair costs

repair or replace any alterations, partitions, fixtures, additions and other
improvements (collectively, "Improvements") which may have been placed in, on or
about the Premises by or for the benefit of Tenant, it being the intent of the
parties that Tenant shall replace such Improvements utilizing insurance proceeds

payable hereunder shall be abated proportionately from the date Tenant vacates
all or a portion of the Premises only to the extent rental abatement insurance
proceeds are received by Landlord and only during the period the Premises are
unfit for occupancy.

           12.1.2  Greater Than 90 Days. If the Premises should be damaged only
                   --------------------

Landlord shall have the option of: (a) terminating the Lease effective upon the
occurrence of such damage, in which event the Rent shall be abated from the date
Tenant vacates the Premises; or (b) electing to repair the Premises, provided
insurance proceeds are available to fully repair the damage (except that
Landlord shall not be required to rebuild, repair or replace any part of the
Improvements which may have been placed In, on or about the Premises by or for
the benefit of Tenant). If Tenant is required to vacate all or a portion of the
Premises during Landlord's repair thereof, the Base Rent payable hereunder shall
be abated proportionately from the date Tenant vacates all or a portion of the
Premises only to the extent rental abatement insurance proceeds are received by
Landlord and only during the period the Premises are unfit for occupancy. In the
event that Landlord should fail to substantially complete such repairs within
one hundred eighty (180) days after the date upon which Landlord is notified by
Tenant of the casualty (such period to be extended for delays caused by Tenant
or because of any items of Force Majeure, as hereinafter defined) and Tenant has
not re-occupied the Premises, Tenant shall have the right, as Tenant's exclusive
remedy, within ten (10) days after the expiration of such one hundred eighty
(180) day period, to terminate this Lease by delivering written notice to
Landlord as Tenant's exclusive remedy, whereupon all rights hereunder shall
cease and terminate thirty (30) days after Landlord's receipt of such notice.

           12.1.3  Greater Than 180 Days. If the Premises should be so damaged
                   ---------------------
that rebuilding or repairs cannot be completed within one hundred eighty (180)
days, either Landlord or Tenant may terminate this Lease by giving written
notice within ten (10) days after notice from Landlord specifying such time
period of repair; and this Lease shall terminate and the Rent shall be abated
from the date Tenant vacates the Premises. In the event that neither party
elects to terminate this Lease, Landlord shall promptly commence and diligently
prosecute to completion the repairs to the Premises, provided insurance proceeds
are available to repair the damage (except that Landlord shall not be required
to rebuild, repair or replace any Improvements which may have been placed in, on
or about the Premises by or for the benefit of Tenant). If Tenant is required to
vacate all or a portion of the Premises during Landlord's repair thereof, the
Base Rent payable hereunder shall be abated proportionately from the date Tenant
vacates all or a portion of the Premises only to the extent rental abatement
insurance proceeds are received by Landlord and only during the period that the
Premises are unfit for occupancy.

     12.2  Tenant's Fault. If the Premises or any portion of the Premises is
           --------------
damaged resulting from the negligence or breach of this Lease by Tenant or any
of Tenant's Parties, Rent shall not be reduced during the repair of such damage
and Tenant shall be liable to Landlord for the cost of the repair caused thereby
to the extent such cost is not covered by insurance proceeds.

<PAGE>
 
     12.3  Uninsured Casualty. In the event that the Premises or any portion of
           ------------------
the Premises is damaged to the extent Tenant is unable to use the Premises and
such damage is not covered by insurance proceeds received by Landlord or in the
event that the holder of any indebtedness secured by the Premises requires that
the insurance proceeds be applied to such indebtedness, then Landlord shall have
the right at Landlord's option either (i) to repair such damage as soon as
reasonably possible at Landlord's expense, or (ii) to give written notice to
Tenant within thirty (30) days after the date of the occurrence of such damage
of Landlord's intention to terminate this Lease as of the date of the occurrence
of such damage. In the event Landlord elects to terminate this Lease, Tenant
shall have the right (but not the obligation) within ten (10) days after receipt
of such notice to give written notice to Landlord of Tenant's intention to pay
the cost of repair of such damage, in which event this Lease shall continue in
full force and effect, Landlord shall make such repairs as soon as reasonably
possible and Tenant shall reimburse Landlord for such repairs within fifteen
(15) days after receipt of an invoice from Landlord. If Tenant is required to
vacate all or a portion of the Premises during Landlord's repair thereof, the
Base Rent payable hereunder shall be abated proportionately from the date Tenant
vacates all or a portion of the Premises only to the extent rental abatement
insurance proceeds are received by Landlord and only during the period that the
Premises are unfit for occupancy. If Tenant does not give such notice within the
ten (l0) day period, this Lease shall terminate automatically as of the date
of the occurrence of the damage. 

     12.4  Waiver. With respect to any damage or destruction which Landlord is
           ------
obligated to repair or may elect to repair, Tenant waives all rights to
terminate this Lease pursuant to rights otherwise presently or hereafter
accorded by law and not specifically set forth herein.

13.  EMINENT DOMAIN.
     --------------

     13.1  Total Condemnation. If all of the Premises is condemned by eminent
           ------------------
domain, inversely condemned or sold under threat of condemnation for any public
or quasi-public use or purpose ("Condemned"), this Lease shall terminate as of
the earlier of the date the condemning authority takes title to or possession of
the Premises, and Rent shall be adjusted to the date of termination.

     13.2  Partial Condemnation. If any portion of the Premises is Condemned and
           --------------------
such partial condemnation materially impairs Tenant's ability to use the
Premises for Tenant's business as reasonably determined by Landlord, Landlord
shall have the option of either (i) relocating Tenant to comparable space within
the Project or (ii) terminating this Lease as of the earlier of the date title
vests in the condemning authority or as of the date an order of immediate
possession is issued and Rent shall be adjusted to the date of termination. If
such partial condemnation does not materially impair Tenant's ability to use the
Premises for the business of Tenant, Landlord shall promptly restore the
Premises to the extent of any condemnation proceeds recovered by Landlord,
excluding the portion thereof lost in such condemnation, and this Lease shall
continue in full force and effect except that after the date of such title
vesting Rent shall be adjusted as reasonably determined by Landlord.

     13.3  Award. If the Premises are wholly or partially Condemned, Landlord
           -----
shall be entitled to the entire award paid for such condemnation, and Tenant
waives any claim to any part of the award from Landlord or the condemning
authority; provided, however, Tenant shall have the right to recover from
Landlord such compensation, if any, as may be specifically awarded to Landlord
in connection with costs in removing Tenant's merchandise, furniture, fixtures,
leasehold improvements and equipment to a new location. No condemnation of any
kind shall be construed to constitute an actual or constructive eviction of
Tenant or a breach of any express or implied covenant of quiet enjoyment.

     13.4  Temporary Condemnation. In the event of a temporary condemnation not
           ----------------------
extending beyond the Term, this Lease shall remain in effect, Tenant shall
continue to pay Rent and Tenant shall receive any award made for such
condemnation except damages to any of Landlord's property. If a temporary
condemnation is for a period which extends beyond the Term, this Lease shall
terminate as of the date of initial occupancy by the condemning authority and
any such award shall be distributed in accordance with the preceding section. If
a temporary condemnation remains in effect at the expiration or earlier
termination of this Lease, Tenant shall pay Landlord the reasonable cost of
performing any obligations required of Tenant with respect to the surrender of
the Premises, unless Landlord receives such costs from the condemning authority.

14.  DEFAULT

thirty (30) consecutive days;

<PAGE>
 
nature of the default is such that more than thirty (30) days are reasonably
required for its cure. Tenant shall not be deemed to be in default if Tenant
commences the cure within the thirty (30) day period and diligently prosecutes
such cure to completion;

           14.l.4  The making of a general assignment by Tenant for the
benefit of creditors: the filing of a voluntary petition by Tenant or the filing
of an involuntary petition by any of Tenant's creditors seeking the
rehabilitation, liquidation or reorganization of Tenant under any law relating
to bankruptcy, insolvency or other relief of debtors and, in the case of an
involuntary action, the failure to remove or discharge the same within sixty
(60) days of such filing; the appointment of a receiver or other custodian to

           14.l.6  The occurrence of an Event of Default set forth in Section
14.l.4 or l5.l.5 with respect to any guarantor of this Lease, if applicable.

     14.2  Remedies.
           --------

           14.2.1  Termination. In the event of the occurrence of any Event of
                   -----------
Default, Landlord shall have the right to give a written termination notice to
Tenant and, on the date specified in such notice, this Lease shall terminate
unless on or before such date all arrears of Rent and all other sums payable by
Tenant under this Lease and all costs and expenses incurred by or on behalf of
Landlord hereunder shall have been paid by Tenant and all other Events of
Default at the time existing shall have been fully remedied to the satisfaction
of Landlord.

                   14.2.l.l  Repossession.  Following termination, without
                             ------------
prejudice to other remedies Landlord may have, Landlord may (i) peaceably re-
enter the Premises upon voluntary surrender by Tenant or remove Tenant therefrom
and any other persons occupying the Premises, using such legal proceedings as
may be available; (ii) repossess the Premises or relet the Premises or any part
thereof for such term (which may be for a term extending beyond the Term), at
such rental and upon such other terms and conditions as Landlord in Landlord's
sole discretion shall determine, with the right to make reasonable alterations
and repairs to the Premises; and (iii) remove all personal property therefrom.

                   14.2.l.2  Unpaid Rent.  Landlord shall have all the rights
                             ----------- 
and remedies of a landlord provided by applicable law, including the right to
recover from Tenant: (a) the worth, at the time of award, of the unpaid Rent
that bad been earned at the time of termination, (b) the worth, at the time of
award, of the amount by which the unpaid Rent that would have been earned after
the date of termination until the time of award exceeds the amount of loss of
rent that Tenant proves could have been reasonably avoided, (c) 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 the loss of rent that Tenant
proves could have been reasonably avoided, and (d) any other amount, and court
costs, necessary to compensate Landlord for all detriment proximately caused by
Tenant's default. The phrase "worth, at the time of award," as used in (a) and
(b) above, shall be computed at the Applicable Interest Rate, and as used in (c)
above, shall be 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%).

                   14.2.2  Continuation. Even though an Event of Default may
                           ------------
have occurred, this Lease shall continue in effect for so long as Landlord does
not terminate Tenant's right to possession; and Landlord may enforce all of
Landlord's rights and remedies under this Lease, including the right to recover
Rent as it becomes due. Landlord, without terminating this Lease, may, during
the period Tenant is in default, enter the Premises and relet the same, or any
portion thereof, to third parties for Tenant's account and Tenant shall be
liable to Landlord for all costs Landlord incurs in reletting the Premises,
including, without limitation, brokers' commissions, expenses of remodeling the
Premises and like costs. Reletting may be for a period shorter or longer than
the remaining Term. Tenant shall continue to pay the Rent on the date the same
is due. No act by Landlord hereunder, including acts of maintenance,
preservation or efforts to lease the Premises or the appointment of a receiver
upon application of Landlord to protect Landlord's interest under this Lease,
shall terminate this Lease unless Landlord notifies Tenant that Landlord elects
to terminate this Lease. In the event that Landlord elects to relet the
Premises, the rent that Landlord receives from reletting shall be applied to the
payment of, first, any indebtedness from Tenant to Landlord other than Base Rent
and Real Property Taxes: second, all costs, including maintenance, incurred by
Landlord in reletting; and, third, Base Rent and Real Property Taxes under this
Lease. After deducting the payments referred to above, any sum remaining from
the rental Landlord receives from reletting shall be held by Landlord and
applied in payment of future Rent as Rent becomes due under this Lease. In no
event, and notwithstanding anything in Section 15 to the contrary, shall Tenant
be entitled to any excess rent received by Landlord. If, on the date Rent is due
under this Lease, the rent received from the reletting is less than the Rent due
on that date. Tenant shall pay to Landlord, in addition to the remaining

                                      10.
<PAGE>
 
Rent due, all costs, including maintenance, which Landlord incurred in reletting
the Premises that remain after applying the rent received from reletting as
provided hereinabove. So long as this Lease is not terminated, Landlord shall
have the right to remedy any default of Tenant, to maintain or improve the
Premises, to cause a receiver to be appointed to administer the Premises and new
or existing subleases and to add to the Rent payable hereunder all of Landlord's
reasonable costs in so doing, with interest at the Applicable Interest Rate from
the date of such expenditure.

     14.3  Cumulative. Each right and remedy of Landlord provided for herein or
           ----------
now or hereafter existing at law, in equity, by statute or otherwise shall be
cumulative and shall not preclude Landlord from exercising any other rights or
remedies provided for in this Lease or now or hereafter existing at law or in
equity, by statute or otherwise. No payment by Tenant of a lesser amount than
the Rent nor any endorsement on any check or letter accompanying any check or
payment as Rent shall be deemed an accord and satisfaction of full payment of
Rent; and Landlord may accept such payment without prejudice to Landlord's right
to recover the balance of such Rent or to pursue other remedies.

15.  ASSIGNMENT AND SUBLETTING. Tenant shall not assign, sublet or otherwise
     -------------------------
transfer, whether voluntarily or involuntarily or by operation of law, the
Premises or any part thereof without Landlord's prior written approval, which
shall not be unreasonably withheld. The merger of Tenant with any other entity
or the transfer of any controlling or managing ownership or beneficial interest
in Tenant, or the assignment of a substantial portion of the assets of Tenant,
whether or not located at the Premises, shall constitute an assignment
hereunder. If Tenant desires to assign this Lease or sublet any or all of the
Premises, Tenant shall give Landlord written notice thereof with copies of all
related documents and agreements associated with the assignment or sublease,
including without limitation, the financial statements of any proposed assignee
or subtenant, forty-five (45) days prior to the anticipated effective date of
the assignment or sublease. Tenant shall pay Landlord's reasonable attorneys'
fees incurred in the review of such documentation plus an administrative fee of
Three Hundred Fifty Dollars ($350.00) for each proposed transfer. Landlord shall
have a period of thirty (30) days following receipt of such notice and all
related documents and agreements to notify Tenant in writing of Landlord's
approval or disapproval of the proposed assignment or sublease. If Landlord
fails to notify Tenant in writing of such election, Landlord shall be deemed to
have approved such assignment or subletting. This Lease may not be assigned by
operation of law. Any purported assignment or subletting contrary to the
provisions hereof shall be void and shall constitute an Event of Default
hereunder. If Tenant receives rent or other consideration for any such transfer
in excess of the Rent, or in case of the sublease of a portion of the Premises,
in excess of such Rent that is fairly allocable to such portion, after
appropriate adjustments to assure that all other payments required hereunder are
appropriately taken into account, Tenant shall pay landlord fifty percent (50%)
of the difference between each such payment of rent or other consideration and
the Rent required hereunder. During any period in which an Event of Default (as
defined in Section 14.1) remains uncured, Landlord may, without waiving any
other rights or remedies, collect rent from the assignee, subtenant or occupant
and apply the net amount collected to the Rent herein reserved and apportion any
excess rent so collected in accordance with the terms of the preceding sentence.
Tenant shall continue to be liable as a principal and not as a guarantor or
surety to the same extent as though no assignment or subletting had been made.
Landlord may consent to subsequent assignments or subletting of this Lease or
amendments or modifications to the Lease by assignees of Tenant without
notifying Tenant or any successor of Tenant and without obtaining their consent.
No permitted transfer shall be effective until there has been delivered to
Landlord a counterpart of the transfer instrument in which the transferee agrees
to be and remain jointly and severally liable with Tenant for the payment of
Rent pertaining to the Premises and for the performance of all the terms and
provisions of this Lease relating thereto arising on or after the date of the
transfer. Subject to the provisions hereof and provided Landlord receives thirty
(30) days prior written notice and a true and correct copy of the assignment
instrument. Landlord hereby consents to the assignment of Tenant's interest in
and to this Lease to any wholly owned subsidiary of Tenant.

16.  ESTOPPEL ATTORNMENT AND SUBORDINATION.
     -------------------------------------

     l6.l  Estoppel. Within ten (l0) days after request by Landlord, Tenant
           --------
shall deliver an Estoppel certificate duly executed (and acknowledged if
required by any lender), in the form attached hereto as Exhibit G, or in such
                                                        ---------
other form as may be acceptable to the lender, which form may include some or
all of the provisions contained in Exhibit G, to any proposed mortgagee,
                                   ---------
purchaser or Landlord. Tenant's failure to deliver said statement in such time
period shall be an Event of Default hereunder and shall be conclusive upon
Tenant that (a) this Lease is in full force and effect, without modification
except as may be represented by Landlord; (b) there are no uncured defaults in
Landlord's performance and Tenant has no right of offset, counterclaim or
deduction against Rent hereunder, and (c) no more than one month's Base Rent has
been paid in advance. If any financier should require that this Lease be amended
(other than in the description of the Premises, the Term, the Permitted Use, the
Rent or as will substantially, materially and adversely affect the rights of
Tenant), Landlord shall give written notice thereof to Tenant, which notice
shall be accompanied by a Lease supplement embodying such amendments. Tenant
shall, within ten (10) days after the receipt of Landlord's notice, meet and
confer with Landlord in good faith with respect to such proposed amendments.

     l6.2  Subordination. This Lease shall be subject and subordinate to all
           -------------
ground leases and the lien of all mortgages and deeds of trust which now or
hereafter affect the Premises or the Project or Landlord's interest therein, and
all amendments thereto, all without the necessity of Tenant's executing further
instruments to effect such subordination. If requested, Tenant shall execute and
deliver to Landlord within ten (10) days after Landlord's request whatever
documentation that may

                                      11.
<PAGE>
 
reasonably be required to further effect the provisions of this paragraph. With
respect to any new mortgage or deed of trust encumbering the Premises after the
date of this Lease, Landlord shall use its best efforts to obtain from such
mortgagee or beneficiary under the deed of trust a non-disturbance agreement in
such party's usual and customary form protecting the interest of Tenant
hereunder.

     l6.3  Attornment. In the event of a foreclosure proceeding, the exercise
           ----------
of the power of sale under any mortgage or deed of trust or the termination of a
ground lease, Tenant shall, if requested, attorn to the purchaser thereupon and
recognize such purchaser as Landlord under this Lease; provided, however,
Tenant's obligation to attorn to such purchaser shall be conditioned upon
Tenant's receipt of a non-disturbance agreement protecting the interest of
Tenant hereunder.

17.  MISCELLANEOUS
     -------------

     17.1  General.
           -------

           17.1.1   Entire Agreement. This Lease sets forth all the agreements

                               -----------------


      THIS ADDENDUM TO LEASE ("Addendum") is attached to and constitutes an
integral part of the Lease between CATELLUS DEVELOPMENT CORPORATION, as
Landlord, and MOHAWK INDUSTRIES, INC., as Tenant. The terms of this Addendum
shall be incorporated in the Lease for all purposes. In the event of a conflict
between the provisions of the Lease and the provisions of this Addendum, this
Addendum shall control.


THE FOLLOWING NEW SECTIONS ARE HEREBY ADDED TO THE LEASE WHICH STATE IN THEIR
ENTIRETY AS FOLLOWS:


18.  Force Majeure Event. For purposes of this Lease, the term "Force Majeure
     -------------------
Event" shall mean and include the following: any delay caused by any action,
inaction, order, ruling, moratorium, regulation, statute, condition or other
decision of any governmental agency having jurisdiction over any portion of the
Project, over the construction anticipated to occur thereon or over any uses
thereof, or by fire, flood, inclement weather, strikes, lockouts or other labor
or industrial disturbance (whether or not on the part of agents or employees of
either party hereto engaged in the construction of the Premises), civil
disturbance, order of any government, court or regulatory body claiming
jurisdiction or otherwise, act of public enemy, war, riot, sabotage, blockade,
embargo, failure or inability to secure materials, supplies or labor through
ordinary sources by reason of shortages or priority, discovery of hazardous or
toxic materials, earthquake, or other natural disaster, or any cause whatsoever
beyond the reasonable control (excluding financial inability) of the party whose
performance is required, or any of its contractors or other representatives,
whether or not similar to any of the causes hereinabove stated.

19.  CPI Adjustment. Effective as of the first day of the thirty-first (31st)
     --------------
month of the Term (the "CPI Adjustment Date"), the Base Rent in effect
immediately before the CPI Adjustment Date shall be increased, in accordance
with the percentage increase, if any, in the Consumer Price Index, to an amount
which is equal to the product of (i) the Index (as hereinafter defined) for the
third month preceding the CPI Adjustment Date, multiplied by (ii) the initial
Base Rent set forth in the Basic Lease Information, divided by (iii) the Basic
Index (as hereinafter defined); provided, however, in no event shall the Base
Rent (as adjusted) in effect immediately prior to the CPI Adjustment Date be
decreased, nor shall it be increased as a result of a CPI adjustment by more
than six percent (6%) per Lease Year, compounded annually. The "Index" shall
mean the Consumer Price Index, All Items, 1982-1984 = 100, All Urban Consumers,
for the Los Angeles/Riverside/Anaheim Area, as published by the United States
Department of Labor, Bureau of Labor Statistics, or its successor index, and the
"Basic Index" shall mean the Index published for the third month preceding the
Commencement Date. The adjusted Base Rent shall be rounded to the nearest $1.00.
If the Index required for the calculation specified in this subsection is not
available on the CPI Adjustment Date in question, Tenant shall continue to pay
the same amount of Base Rent payable during the period immediately preceding the
CPI Adjustment Date until the Index is available and the necessary calculation
is made. As soon as such calculation is made, Tenant shall immediately pay to
Landlord the amount of any underpayment of Base Rent for the month(s) that may
have elapsed. In the event the compilation or publication of the Index shall be
transferred to any other governmental department, bureau or agency or shall be
discontinued, the index most nearly the same as the Index shall be used to make
such calculation.

20.  Options to Extend.
     ----------------- 


     20.1 Terms of Options. Provided (i) Tenant is not in default under the 
          ----------------

Tenant is occupying at least ninety percent (90%) of the Premises, including any
expansion space, and (iii) Landlord has not given more than two (2) notices of
default in any twelve (12) month period for nonpayment of monetary obligations,

that Landlord shall have no additional obligation for free rent, leasehold
improvements or for any other tenant inducements for the Extension Terms. Base
Rent shall be increased (but not decreased) as set forth below. There shall be

Tenant must exercise its options to extend this Lease by giving Landlord written
notice of its election to do so not less than one hundred eighty (180) days
prior to the end of the initial Term, or the First Extension Term, as
applicable. Any notice not given in a timely manner shall be void, and Tenant
shall be deemed to have waived its extension rights. The extension options set
forth herein are personal to Tenant and shall not be included in any assignment
of this Lease.

     20.2 Base Rent During First Extension Term. Effective as of the first day
          -------------------------------------

month thereafter (the "First Extension CPI Adjustment Date(s)"), the monthly
Base Rent shall be increased in accordance with the percentage increase, if any,
in the Consumer Price Index, calculated in the manner set forth in Section 19;
provided, however, in no event shall the Base Rent (as adjusted) in effect
immediately prior to the applicable First Extension CPI Adjustment Date be
decreased, nor shall it be increased as a result of a CPI adjustment by more
than six percent (6%) per Lease Year, compounded annually.

     20.3 Base Rent During Second Extension Term. The monthly Base Rent payable
          --------------------------------------                               
for the first thirty (30) months of the Second Extension Term shall be increased
(but not decreased) to 98% of the fair market rental rate ("Market Rent") to be
determined as follows:

          20.3.1  Agreement on Base Rent. Landlord and Tenant shall have thirty
                  ----------------------                                       
(30) days after Landlord receives the exercise notice in which to agree on the
Base Rent during the Second Extension Term. Notwithstanding anything in this
Section 20.3 to the contrary, in no event shall the Base Rent for the Second
Extension Term be less than the Base Rent in effect immediately prior to the
Second Extension Term.

          20.3.2  Appraisal. If Landlord and Tenant are unable to agree upon the
                  ---------                                                     
Base Rent for the Second Extension Term within such thirty (30) day period, then
within fifteen (15) days after the expiration of the thirty (30) day period,
each party, by giving notice to the other party, shall appoint a real estate
appraiser who is a current member of the American Institute of Real Estate
Appraisers, with at least five (5) years of experience appraising building space
comparable to the Premises in the city and county where the Premises is located
to determine the Market Rent. Market Rent shall mean the monthly amount per
rentable square foot in the Premises that a willing, non-equity new tenant would
pay and a willing landlord would accept at arm's length for space in a
comparable building or buildings, with comparable tenant improvements, in a
comparable location, giving appropriate consideration to monthly rental rates
per rentable square foot, the presence or absence of rent escalation clauses
such as operating expense and tax pass-throughs, length of lease term, size and
location of premises being leased and other

                                      16.
<PAGE>
 
generally applicable terms and conditions of tenancy for a similar building or
buildings. If the two (2) appraisers are unable to agree on the Market Rent for
the Second Extension Term within twenty (20) days, they shall select a third
appraiser meeting the qualifications stated in this Section within five (5) days
after the last day the two (2) appraisers are given to set the Market Rent for
the Second Extension Term. The third appraiser, however selected, shall be a
person who has not previously acted in any capacity for either party. Within
twenty (20) days after the selection of the third appraiser, a majority of the
appraisers shall set the Market Rent for the Second Extension Term. If a
majority of the appraisers is unable to set the Market Rent within the twenty
(20) day period, the two (2) closest appraisals shall be added together and
their total divided by two (2). The resulting quotient shall be the Market Rent
for the first thirty (30) months of the Second Extension Term. Each party shall
be responsible for the costs, charges and fees of the appraiser appointed by
that party plus one-half of the cost of the third appraiser.

          20.3.3  Amendment of Lease. Immediately after the Base Rent is 
                  ------------------                                     
determined pursuant to this Section 20.3, Landlord and Tenant shall execute an
amendment to this Lease stating the new Base Rent in effect.

          20.3.4  Base Rent Increase During Second Extension Term. Effective 
                  -----------------------------------------------            
as of the first day of the thirty-first (31st) month of the Second Extension
Term (the "Second Extension CPI Adjustment Date"), the monthly Base Rent shall
be increased in accordance with the percentage increase, if any, in the Consumer
Price Index, calculated in the manner set forth in Section 19; except that the
Index shall be multiplied by the monthly Base Rent payable during the first
thirty (30) months of the Second Extension Term, and the Basic Index shall mean
the Index published for the third month preceding the commencement of the Second
Extension Term; provided, however, in no event shall the Base Rent in effect
after the Second Extension CPI Adjustment Date be less than the Base Rent in
effect immediately preceding the Second Extension CPI Adjustment Date.

                                  -----------

Tenant Improvements.
------------------- 

1.1  Landlord shall construct or cause to be constructed in and to the Premises,
at Landlord's cost and expense, not to exceed One Hundred Eighty Thousand
Dollars ($180,000.00), certain tenant improvements, including space planning,
permits and related costs (the "Tenant Improvements"), substantially in
accordance with the space plan or other appropriate exhibit (the "Space Plan")
attached hereto, marked Exhibit B-1 and made a part hereof and in accordance
                        -----------                                         
with Landlord's current building standards. If said Exhibit is not attached, the
Space Plan shall be prepared by Landlord and submitted to Tenant for approval,
which approval shall be given within five (5) days following receipt thereof,
and evidenced by Tenant's signature thereon. A failure by Tenant to respond
within said five (5) day period shall be deemed approval. Upon approval by both
parties, the Space Plan shall be deemed incorporated herein by reference,
although not attached hereto.

1.2  The Tenant Improvements shall include costs approved by Landlord and
associated with the design, permit process and construction (including, a fee
equal to five percent (5%) of the total cost thereof as reimbursement for the
expense of Landlord's administration and coordination) of the Tenant
Improvements, including but not limited to, architect's fees, plan check and
permit fees, and fees for utility and telephone service hook-ups. The Tenant
Improvements shall not include any improvements which Landlord, in its sole
discretion, considers specialized, or any equipment or trade fixtures of Tenant,
nor any improvements not shown on the Space Plan which Tenant may desire or
governing agencies may require.

1.3  In the event that Tenant desires any change in the Tenant Improvements
which is reasonable and practical (which shall be conclusively determined by the
Architect), such change may only be requested by the delivery to Landlord by
Tenant of a proposed written "Change Order" specifically setting forth the
requested change. Landlord shall have five (5) business days from the receipt of
the proposed Change Order to provide Tenant with the Architect's disapproval of
the proposed change stating the reason(s) for such disapproval, or if the
Architect approves the proposed change, the following items: (i) a summary of
any increase in the cost caused by such change (the "Change Order Cost"), (ii) a
statement of the number of days of any delay caused by such proposed change (the
"Change Order Delay"), and (iii) a statement of the cost of the Change Order
Delay (the "Change Order Delay Expense"), which Change Order Delay Expense shall
be the product of the number of days of delay multiplied by $2,500.00. Tenant
shall then have three (3) business days to approve the Change Order Cost, the
Change Order Delay and the Change Order Delay Expense. If Tenant gives timely
written notice of approval of the Change Order Cost, the Change Order Delay and
the Change Order Delay Expense, Landlord shall promptly execute the Change Order
and cause the appropriate changes to the Plans and Specifications to be made.
Tenant's approval shall include full payment of the Change Order Cost and
Change Order Delay Expense. If Tenant fails to respond to Landlord within said
three (3) business day period, the Change Order Cost, the Change Order Delay and
the Change Order Delay Expense shall be deemed disapproved by Tenant and
Landlord shall have no further obligation to perform any work set forth in the
proposed Change Order. The Change Order Cost shall include all costs associated
with the Change Order, including, without limitation, architectural fees and
construction costs, as conclusively determined by the Architect and the General
Contractor, respectively, together with a five percent (5%) fee of these costs
as reimbursement for the expense of administration and coordination of such
Change Order by Landlord. The Change Order Delay shall include all delays caused
by the Change Order, including, without limitation, all architectural and
construction delays, as conclusively determined by the Architect and the General
Contractor, respectively.

1.4  Landlord hereby to assign to Tenant, upon request, the benefit of any and
all contractor's and manufacturer's warranties received by Landlord in
connection with the construction of the Tenant Improvements.
