         THIS LEASE ("Lease"), dated for reference and effective as of the 11th
day of July, 2000, made and entered into by and between PACIFIC PLAZA CARMEL
VALLEY LLC, a California limited company ("Landlord"), and JNI CORPORATION a
Delaware corporation ("Tenant"), for space in the building located at 10955
Vista Sorrento Parkway (the "Building") located in the City of San Diego, County
of San Diego, State of California, in that development commonly known as Pacific
Plaza at Torrey Hills (the "Project"), described more particularly on the Legal
Description, attached hereto as Exhibit A, shall be upon the terms and
conditions contained hereinafter.

1.        PREMISES

1.1 PREMISES. Landlord leases to Tenant, subject to the provisions of this
Lease, the Premises in the Building as set forth in the Basic Lease Information,
the usable space of which is shown on the Building Floor Plans, attached hereto
as Exhibit B. The rentable square feet of the Premises, Building and Project
shall be as set forth in the Basic Lease Information, subject however, to
adjustment as set forth in Section 1.05. By entering the Premises, Tenant shall
be deemed to accept the same (subject, however, to the provisions of Section
1.07) and subject to all applicable municipal, county, state and federal
statutes, laws, ordinances, including zoning ordinances, and regulations
governing and relating to the Tenant's use, occupancy or possession of the
Premises. Tenant acknowledges that the only warranties and representations
Landlord has made in connection with the physical condition of the Premises or
Tenant's use of the same upon which Tenant has relied directly or indirectly for
any purpose are those expressly provided in this Lease.

1.2 EXHIBITS. The following Exhibits are attached to this Lease after the
signatures and by reference thereto are incorporated herein:
                  Exhibit A         Legal Description
                  Exhibit B         Building Floor Plans and Site Plan
                  Exhibit C         Preliminary Plans
                  Exhibit D         Work Letter
                  Exhibit E         Letter of Credit
                  Exhibit F         Addendum to Lease

1.3 COMMON AREAS. Tenant shall have, as appurtenant to the Premises and subject
to reasonable rules and regulations from time to time made by Landlord the right
to the use of the following in common (the "Common Areas"):

                  (a) Building Common Area. The common stairways and accessways,
lobbies, entrances, stairs, elevators, maintenance and utility service areas and
any passageways thereto, and the common pipes, ducts, conduits, wires and
appurtenant equipment serving the Premises (`the "Building Common Areas");

                  (b) Project Common Area. The common walkways, sidewalks,
landscape areas, parking spaces and driveways necessary for access to the
Project and Parking Area (the "Project Common Areas"); and;

                  (c) Parking Area. The common area located in the Project
parking lot area ("Parking Area") as shown on Exhibit "B.".

1.4 LANDLORD'S RESERVED RIGHTS IN COMMON AREAS AND PROJECT. Landlord reserves
full control over the Common Areas to the extent not inconsistent with Tenant's
quiet enjoyment and use of the Premises. This reservation includes but is not
limited to right of Landlord, to grant easements and

                                       1

<PAGE>

licenses to others and the right to maintain or establish ownerships of the
Building separate from fee title to the land and other improvements in the
Project, to the extent not inconsistent with Tenant's quiet enjoyment and use of
the Premises as granted by this Lease. Tenant shall, should Landlord so request,
promptly join with Landlord in execution of such documents as may be reasonably
appropriate to assist Landlord to implement any such action provided Tenant need
not execute any document which is of a nature wherein liability is created in
Tenant or if, by reason of the terms of such document, Tenant may be deprived of
the quiet enjoyment and use of the Premises as granted by this Lease. Landlord
reserves the right from time to time to do any of the following, so long as
Landlord does not materially and unreasonably interfere with Tenant's use or
quiet enjoyment of the Premises as granted by this Lease:

(a) to install, use, maintain, repair, relocate and replace any pipes, ducts,
conduits, wires and appurtenant meters and equipment for service to the Building
above the ceiling surfaces, below the floor surfaces, within the walls and in
the central core areas;

(b) to change the lines of the lot or lots on which the Project stands ("Lot")
and to redesign and restripe the parking facilities around the Building and make
other reasonable changes and grant other rights thereto, including without
limitation, the granting of easements, rights of way and rights of ingress and
egress and similar rights to users of parcels in or adjacent to the parcel on
which the Building is situated; and

(c) to alter or relocate any common areas or other facilities. Notwithstanding
the foregoing, Landlord shall not reduce the number of parking spaces in the
Parking Area by more than two percent (2%) without Tenant's approval. Landlord
reserves the right to grant exclusive use to portions of the Parking Area to
specific tenants subject to Tenant's rights to parking under Section 1.06.
Tenant's approval rights set forth in this Section 1.04 shall be effective only
for so long as Tenant and any Affiliate Transferee, in the aggregate, continue
to lease at least eighty percent (80%) of the Rentable Area in the Building.

1.5 RENTABLE AREA. As used in this Lease, the
Rentable Area of the Premises, Building and Project shall be the square footage
designated in the Basic Lease Information, subject however, to adjustment as set
forth in this Section 1.05.

                  (a) The term "Rentable Area" as used in this Lease shall mean
the floor rentable area and the term "Usable Area" as used in this Lease shall
mean the floor Usable Area as both terms are measured and determined applying
the Standard Method for Measuring Floor Area in Office Buildings" (ANSI/BOMA
Z65.1, 1996).

                  (b) The term "Rentable Area" when applied to Tenant is that
area equal to the Rentable Area of the Premises. The term "Usable Area" when
applied to Tenant is that area equal to the Usable Area of the Premises. The
term "Rentable Area," when applied to the Project, is that area equal to the
Rentable Area of the buildings in the Project, including the Building. The term
"Usable Area," when applied to the Project, is that area equal to the Usable
Area of the buildings in the Project, including the Building.

                  (c) The initial Rentable Area of the Premises, the Building
and the Project as set forth in the Basic Lease Provisions is an estimate of the
area which will, upon completion of development of the Building, constitute the
Rentable Area of the Premises, the Building and the Project, respectively. Due
to changes in configurations which may be required in connection with the
development of the Building and the Project, the Rentable Area set forth in the
Basic Lease Provisions for the Premises, the Building and the Project is subject
to modification. In the event the Rentable Area applicable to the Premises, the
Building or the Project differs from such initial Rentable Area, the Basic
Annual Rent, monthly installments of Basic Annual Rent. Tenant's Share of
Project Operating Expenses and Tenant's Share of Building Operating Expenses
shall be adjusted upward or downward, as applicable, based on the actual
Rentable Area of the Premises, the Building and the Project.

                  (d) Upon Substantial Completion of the Building Shell, the
square feet of Rentable Area in the Premises shall be field measured and
confirmed by the Project Architect (as defined in the Work Letter) and shall be
presented to Tenant in writing. Within ten (10) business days, Tenant shall
either accept or reject Landlord's calculation. If Tenant accepts such
calculation, it shall become conclusive and binding on Landlord and Tenant as to
the actual square feet of Rentable Area for the

                                       2

<PAGE>

Premises. If Tenant rejects such calculation, Tenant shall have the Building
field measured by Tenant's Architect (as defined in the Work Letter) using the
same measurement method. If the Rentable Area as determined by the Project
Architect and by Tenant's Architect differs by less than two hundred (200)
square feet, the Rentable Area as determined by the Project Architect shall be
conclusive and binding on Landlord and Tenant. If the Rentable area as
determined by the Project and by Tenant's Architect differs by more than two
hundred (200) square feet and the Project Architect and Tenant's Architect
cannot agree on the Rentable Area of the Premises, they shall select a third
independent architect to field measure the Building using the same measurement
method and the determination of the Rentable Area by such third party architect
shall be conclusive and binding on Tenant and Landlord. Landlord and Tenant
shall each pay one-half (1/2) of the fees and expenses of the independent
architect. The same procedure shall be applied to determining the Rentable Area
of all buildings in the Project.

1.6 TENANT'S PARKING ENTITLEMENTS. Tenant shall be entitled to the exclusive
use, without charge, during the Term and any extension thereof, of parking
spaces in the area of the Project designated as the parking area for the
Building. The location of such parking spaces shall be as shown on Exhibit B
attached hereto. Tenant shall be entitled to install signage in conformance with
the Tenant's Improvement Plans indicating such spaces as Tenant's parking.
Landlord shall have no responsibility for policing or otherwise enforcing
parking rights in the Project; provided, however, if unauthorized parking the
Parking Area causes Tenant persistently to be deprived of its rights to use the
Parking Area pursuant to this Lease, then Landlord shall, after written notice
from Tenant, take reasonable action to insure that Tenant's parking entitlements
pursuant to this Lease are available to Tenants and its invitees.

1.7 Condition of Premises. Landlord warrants and covenants to Tenant that, as of
the Lease Term Commencement Date: (a) the Building Shell shall be constructed in
accordance with Landlord's Plans, as modified pursuant to the terms of the Work
Letter; (b) the electrical, plumbing or mechanical systems in the Building
("Building Systems") shall be new, properly installed and in good working order;
(c) to Landlord's actual knowledge, the Building Shell shall comply with the
American's with Disabilities Act, except for such noncompliance as shall not
have a material adverse effect on Tenant's rights or obligations under this
Lease or Tenant's ability to use the Premises; and (d) to Landlord's actual
knowledge, there shall be no Hazardous Substances located in, on or about the
Building or the Premises, except for such Hazardous Substances brought on the
Premises or Project by Tenant pursuant to the provision of Article 14 . Tenant
shall notify Landlord within thirty (30) days after Tenant becomes aware of any
breach of the foregoing warranty and covenant; provided, however, Tenant shall
have no recourse against Landlord for any breach of the foregoing warranty and
covenant that could have been discovered by a visual inspection of the Premises
and the public spaces located within the Building unless Tenant notifies
Landlord of such breach within thirty (30) days after the Lease Commencement
Date. With respect to the covenants and warranties in this Section 1.07,
Landlord shall repair or replace the defective elements of the Building Shell or
Building Systems at its own cost and not as an Operating Expense within thirty
(30) days after Landlord receives notice of such defect from Tenant; provided,
however, if by the nature of such correction more than thirty (30) days is
required to effect such correction, Landlord shall not be in default hereunder
if such correction is commenced within such thirty (30) days period and is
diligently pursued to completion. So long as Landlord satisfies the covenant set
forth in the preceding sentence, Tenant shall have no other remedy for the
failure of the covenants and warranties set forth in this Section 1.07. Except
as otherwise set forth in this Section 1.07, Landlord makes no representations
and warranties regarding the condition of the improvements in the Premises or
their fitness for Tenant's intended use. Landlord shall have no obligation to
make any other improvements to the Premises and, to the maximum extent permitted
by law, Tenant hereby agrees to accept the Premises in their "as-is" condition.

2 . TENANT'S IMPROVEMENTS

2.1 PLANS. For the purposes of this Article 2, capitalized terms not otherwise
defined elsewhere in this Lease shall have the meanings set forth in Exhibit "D"
attached hereto (the "Work Letter"). Tenant shall submit to Landlord preliminary
plans and outline specifications identified in Exhibit C

                                       3

<PAGE>

("Preliminary Plans") for the construction of the tenant improvements to the
Premises ("Tenant's Improvements") in accordance with the Work Letter. Once
Landlord has approved the preliminary plans and outline specifications submitted
by Tenant in accordance with the Work Letter, Tenant shall have final plans and
specifications ("Tenant Improvement Plans") prepared in substantial conformity
with the Preliminary Plans. Preparation and approval of the Tenant Improvement
Plans and any changes requested by Tenant thereto shall be made only in
accordance with the Work Letter. Landlord shall construct Tenant's Improvement
Work (as defined in the Work Letter) in accordance with the approved Tenant's
Improvement Plans, all in accordance with the provisions of the Work Letter. All
costs and expenses associated with such work, including but not limited to the
costs of the Tenant's Improvement Work, Tenant's moving costs (subject to the
limitation of Section 2.02 below), fees of, and other amounts payable to,
Tenant's Architect and Tenant's engineers and other building and/or construction
consultants, building permit fees, Landlord's Contractor's Fee (as defined in
the Work Letter) and all other costs and expenses chargeable to the Tenant
Improvement Fund pursuant to Exhibit "D" to this Lease (collectively the "Tenant
Improvement Costs"), shall be paid by Landlord from the Tenant Improvement Fund.

2.2 TENANT IMPROVEMENT ALLOWANCE. Landlord shall provide Tenant with a basic
allowance for construction of Tenant's Improvements Work and to offset such
other Tenant Improvement Costs as Tenant may incur in connection with this Lease
in an amount determined by multiplying the sum of Thirty Five Dollars ($35.00)
times the number of square feet of Usable Area in the Premises as determined in
accordance with Section 1.05 ("Tenant Improvement Allowance"). All Tenant
Improvement Costs in excess of the Tenant Improvement Allowance ("Tenant's
Improvement Contribution") shall be paid by Tenant. The initial Tenant's
Improvement Contribution shall be paid to Landlord fifteen (15) days after
Tenant shall have approved a Cost Estimate or Revised Cost Estimate (as each
term is defined in the Work Letter) and Landlord and Tenant have thereafter
agreed on an estimate of Tenant Improvement Costs. In the event the actual
Tenant Improvement Costs are less than the sum of the Tenant Improvement
Allowance and Tenant's Improvement Contribution, then Landlord shall pay to
Tenant within ten (10) days after such determination the amount by which the sum
of the Tenant Improvement Allowance and Tenant's Improvement Contribution
exceeded the actual Tenant Improvement Costs; provided , however, in no event
shall the Landlord be required to pay an amount greater than the amount of
Tenant's Improvement Contribution. The Tenant Improvement Allowance and Tenant's
Improvement Contribution are herein collectively referred to as the "Tenant
Improvement Fund". In no event, however, shall amounts paid for Tenant's moving
costs from the Tenant Improvement Fund exceed Two Dollars ($2.00) per square
foot of Usable Area in the Premises. In the event that the Tenant Improvement
Costs exceed the Tenant Improvement Allowance, Tenant may elect by delivering
written notice to Landlord within ten (10) days after the estimate of Tenant
Improvement Cost is obtained pursuant to the Work Letter, to obtain from
Landlord an additional allowance for the Tenant's Improvement Work ("Additional
Tenant Improvement Allowance") in an amount not to exceed $5.00 per square foot
of Usable Area in the Premises. The Additional Tenant Improvement Allowance
shall be fully amortized at nine percent (9%) interest per annum on the unpaid
balance over the initial Term of this Lease and shall be repaid by Tenant to
Landlord in equal monthly payments commencing on the Term Commencement Date as
Additional Rent.

2.3 CONSTRUCTION. Landlord shall cause the Tenant's Improvement Work in the
Premises to be constructed substantially in accordance with the Tenant's
Improvement Plans and the Work Letter. Subject to the provisions of Section 2.04
below, Tenant shall pay all costs of constructing Tenant's Improvements, except
that Tenant shall be entitled to receive the Tenant Improvement Allowance from
Landlord in accordance with the terms and conditions of Section 2.02 of this
Lease.

2.4 FAILURE TO COMPLETE CONSTRUCTION. Tenant's only remedies for Landlord's
failure to cause Substantial Completion (as defined in the Work Letter) of
the Tenant's Improvement Work and the Landlord's Work (as each term is
defined in the Work Letter, and collectively, the "Improvements") to occur on
or before the Estimated Term Commencement Date, as extended pursuant to the
Work Letter, shall be as set forth in this Section 2.04. If Substantial
Completion of the Improvements has not occurred on or before the date which
is six (6) months following the Estimated Term Commencement Date (the

                                       4
<PAGE>

"Termination Option Date"), Tenant shall have the option to terminate this Lease
by the delivery to Landlord of written notice within ten (10) days after the
Termination Option Date or any one month anniversary of the Termination Option
Date until Substantial Completion of the Improvements occurs. Tenant shall not
be entitled to terminate the Lease for any delay in completion of the Premises
prior to the Termination Option Date. If it appears that Substantial Completion
of the Improvements may not occur on or before the Estimated Term Commencement
Date, as extended pursuant to the Work Letter (the "Scheduled Term Commencement
Date"), Landlord shall be entitled to incur overtime charges ("Overtime
Charges") with Landlord's Contractor and shall use commercially reasonable
efforts to accelerate the completion of Tenant's Improvement Work to meet the
Scheduled Term Commencement Date. If Tenant fails to submit a complete and fully
detailed set of Tenant's Improvement Plans to the City for plan check and
approval on or before September 15, 2001, then Tenant shall reimburse Landlord
within ten (10) days of Landlord's written request therefore for all Overtime
Charges incurred by Landlord relating to such failure. In the event Tenant
submits a complete and detailed set of Tenant's Improvement Plans to the City
for plan check and approval on or before September 15, 2001, and the City does
not approve Tenant's Improvement Plans or does not issues building permits for
Tenant's Improvements on of before December 15, 2001, then any Overtime Charges
payable to Landlord's Contractor shall be payable one-half (1/2) by Landlord and
one half (1/2) by Tenant. If Tenant submits a complete and fully detailed set of
Tenant's Improvement Plans to the City for plan check and approval on or before
September 15, 2001, and the City issues building permits for Tenant's
Improvements on of before December 15, 2001, then any Overtime Charges payable
to Landlord's Contractor shall be payable by Landlord. No Overtime Charges shall
be paid from the Tenant Improvement Fund.

3 . TERM

3.1 COMMENCEMENT OF TERM. The Lease shall be for the Term set forth in the Basic
Lease Information, commencing upon Term Commencement Date. The Term Commencement
Date shall be the later of: (i) the date set forth in the Basic Lease Provisions
as the Estimated Term Commencement Date; (ii) three days after the date (A)
Landlord delivers written notice that the Premises are ready for occupancy and
(B) Substantial Completion of the Improvements has occurred, or (iii) three (3)
days after the date the Premises would have been ready for occupancy and
Substantial Completion of the Improvements would have occurred, had there been
no Tenant Delays as set forth in the Work Letter.

3.2 EARLY OCCUPANCY. Subject to the availability of the Premises and the
issuance by the City of a temporary certificate of occupancy, Tenant shall be
permitted to move its furniture, trade fixtures, equipment, machinery, goods and
supplies into the Premises prior to the Term Commencement Date; the period
between the date Tenant commences to occupy the Premises and the Term
Commencement Date being hereinafter referred to as the "Early Occupancy Period."
Tenant shall be permitted to commence to occupy the Premises as soon as
Substantial Completion of the Improvements occurs and a temporary certificate of
occupancy has been issued by the City.. Such occupancy of the Premises shall be
subject to all the provisions of this Lease, except that Tenant shall not be
required to pay Monthly Base Rent for the Early Occupancy Period; provided,
however, that Tenant shall have provided Landlord proof of Tenant's insurance as
set forth in Section 5.05; and provided further that Tenant shall pay or
reimburse Landlord for all utilities and services to the Premises during the
Early Occupancy Period. All furniture, materials, work, installations, equipment
and decorations of any nature brought upon or installed in the Premises prior to
the Term Commencement Date shall be at Tenant's sole risk. Neither Landlord nor
any party acting on Landlord's behalf shall be responsible for any damage or
loss or destruction of such items brought to or installed in the Premises prior
to the Term Commencement Date unless such damage, loss or destruction results
from Landlord's gross negligence or intentional misconduct.

3.3 NOTICE OF LEASE DATES. Within ten (10) days after Landlord's written
request, Tenant shall execute a written confirmation of the commencement of the
Term and expiration date of the Term in a form reasonably provided by Landlord.
Such a notice shall be binding upon Tenant unless Tenant objects thereto in
writing within such ten (10) day period.

                                       5
<PAGE>

3.4 OPTION TO EXTEND TERM. Tenant shall have the option to extend the Term of
this Lease for the entire Premises for two (2) additional periods of five (5)
years each (the "Premises Options"). The period of the First Premises Option is
referred to herein as the "First Option Term", and the period of the second
Premises Option is referred to as the "Second Option Term.". The First Option
Term and the Second Option Term are sometimes hereinafter collectively referred
to as the "Option Term". Tenant shall have no right or interest to exercise any
Premises Option unless: (a) Tenant gives the Landlord written notice of its
intent to exercise the Premises Option no earlier than three hundred sixty (360)
days prior to the end of the Term, or any prior extension thereof, and no later
than three hundred (300) days prior to the end of the Term, or any prior
extension thereof (the "Extension Notice"); (b) There shall be no uncured Event
of Default on the date the Extension Notice is delivered to Landlord and on the
date the Option Term commences; (c) Tenant or an Affiliate Transferee occupies
more than fifty percent (50%) of the Rentable Area of the Premises; and (d)
Tenant has not filed for or sought protection under any bankruptcy statute.
Annual Base Rent during the First Option Term shall be as set forth in the Basic
Lease Provisions of this Lease and Base Rent during the Second Option Term shall
be as set forth in Section 4.01(b) of the Lease. Time is of the essence with
respect to Tenant's exercise of the Premises Option. Tenant's failure to exactly
comply with any of the time or other requirements herein, shall cause the
Premises Option to automatically expire and, in such event, this Lease shall
terminate upon the expiration of the Term. The option to extend the Term
pursuant hereto for the Option Term shall be personal to Tenant and shall not be
exercisable by or for the benefit of any assignee, subtenant or other transferee
of Tenant, except that the Premises Option may be transferred by Tenant to an
Affiliate Transferee in connection with a Transfer of the entire Lease to an
Affiliate Transferee and may be exercised by such Affiliate Transferee.

3.5 DAYS. Except for the Rent payment requirements of Articles 4 and 6, when
time periods of ten (10) days or less are provided in this Lease, unless
"calendar days" is expressly stated, such time periods are to be calculated such
that "days" shall mean business days, regardless of whether "business days" is
expressly stated. The option to extend the Term pursuant hereto for the Option
Term shall be personal to Tenant and shall not be exercisable by or for the
benefit of any assignee, subtenant or other transferee of Tenant. As used
herein, the term "business day" shall mean each day other than Saturdays and
Sundays and any other day designated as a Federal holiday pursuant to 5 U.S.C.
ss. 6105, other than Columbus Day.

4 . RENT

4.1 BASE RENT.
                  (a) INITIAL TERM. The Annual Base Rent shall be the amount set
forth in the Basic Lease Information payable in equal monthly installments of
Monthly Base Rent as set forth in the Basic Lease Information. Tenant shall pay
the Monthly Base Rent to Landlord in advance upon the first day of each calendar
month of the Term, except that the Monthly Base Rent for the first month of the
Term shall be payable upon execution of this Lease, at Landlord's address or at
such other place designated by Landlord in a notice to Tenant, without any prior
demand therefor and without any deduction, abatement or setoff whatsoever, in
lawful money of the United States of America. If the Term shall commence or end
on a day other than the first day of a calendar month, then Tenant shall pay, as
rent for such partial calendar month, a pro rata portion of the Monthly Base
Rent, prorated on a per diem basis, with respect to the portions of the
fractional calendar month included in the Term. Tenant shall pay rent for the
last calendar month of the Term on the first day of the last calendar month of
the Term. Because Tenant will have paid a full month's Base Rent for the first
fractional calendar month of the Term if the Term shall commence on a day other
than the first day of a calendar month, Tenant's Monthly Base Rent for the first
full calendar month of the Term shall be reduced by an amount equal to the
excess of (i) the amount Tenant actually paid as Monthly Base Rent for the first
fractional calendar month of the Term and (ii) the amount of Monthly Base Rent
that actually accrued with respect to such fractional calendar month. Upon
executing this Lease, Tenant shall pay the first full month's installment of the
Monthly Base Rent owing hereunder along with Tenant's Security Deposit as
provided in Section 4.05 below.

                                       6
<PAGE>

                  (b) OPTION TERM. During the first year of the Second Option
Term, if it occurs, Tenant shall pay to Landlord Base Rent equal to "Market
Rent" (as defined below) for the Premises determined as of the commencement date
of the Second Option Term, as such Base Rent shall be adjusted annually as set
forth in Section 4.03 below. As used herein, "Market Rent" shall mean the price
that a ready and willing tenant would pay, at commencement of the Second Option
Term, as monthly base rent to a ready and willing landlord of similar space in a
Class "A" office building in the geographical area known as Del Mar
Heights/Torrey Hills ("Similar Space"), if such Similar Space were offered for
lease on the open market for a reasonable period of time and be the sum of the
fair market annual rental rate per rentable square foot multiplied by the
Rentable Area of the Premises (as set forth in the Basic Lease Information).
Market Rent shall be determined as follows: (a) as mutually agreed by Landlord
and Tenant within ten (10) days of Landlord's delivery to Tenant of Landlord's
opinion of the Market Rent for the first year of the Second Option Term
("Landlord Rent Notice"), which shall be delivered to Tenant within ten (10)
days after Landlord receives Tenant's written Notice to Extend; or (b) in the
event that Landlord and Tenant are unable to so agree, the Market Rent shall be
determined by concurrent appraisals pursuant to Section 4.01(c) below. Tenant
shall have the right to withdraw its Extension Notice by written notice to
Landlord delivered to Landlord within thirty (30) days after delivery to Tenant
of Landlord's Rent Notice. In determining Market Rent, appraisers shall take
into account the duration of the Second Option Term, the quality and prestige of
the Building and Premises, recent monthly new and renewal rental rates for
Similar Space imputed to the commencement of the Second Option Term, and all
relevant economic terms of this Lease, it being the intent that Market Rent, as
so determined, should reflect the total economic package which would be offered
at the time of commencement of the Second Option Term to a tenant for the
Premises on a new lease or lease renewal basis, or substantially Similar Space
in a building of similar quality and value of tenant improvements (without
consideration of depreciation or amortization on an accounting basis) and
location under a lease with substantially the same terms and provisions as the
applicable terms and provisions of this Lease ("Market for Similar Space"),
without discounting the rent for the creditworthiness of the tenant or for the
real estate leasing commissions. Notwithstanding the foregoing, in no event
shall the Market Rent as so determined be less than the Base Rent for the
calendar year immediately preceding the commencement of the Option Term. In
determining the rental rate of similar space, the parties and the appraisers
shall take into consideration the following concessions: (i) Rental abatement
concessions, if any, being granted to tenants in connection with Similar Space;
(ii) Tenant improvements or allowances provided or to be provided for the
Similar Space on a new lease or lease renewal basis; and (iii) All other
monetary concessions not otherwise excluded above, if any, being granted to
tenants in connection with the Similar Space.

For example, if the parties, in applying the above criteria, determine that (1)
leases of comparable space provide a new or renewal tenant with comparable space
at a base rent rate of two dollars ($2.00) per square foot of Rentable Area per
month, with four (4) months free rent, and a thirty dollar ($30.00) per square
foot of Usable Area tenant improvement allowance where the value of existing
improvements in the comparable space is five dollars ($5.00) per square foot of
Usable Area, and (2) the value of the existing improvements in the Premises is
ten dollars ($10.00) per square foot of Usable Area, then the Fair Market Rental
Value of the Premises shall not be a base rent of two dollars ($2.00) per square
foot of Rentable Area per month only but shall be the equivalent of a two
dollars ($2.00) per square foot of Rentable Area base rent, four (4) months free
rent, and a twenty-five dollar ($25.00) per square foot of Usable Area tenant
improvement allowance or payment in lieu of such allowance.

                  (c)      MARKET RENT APPRAISAL PROCEDURE.

                           (i)      If Tenant  rejects the Market Rent  proposed
by Landlord in Landlord's Rent Notice, Landlord and Tenant shall attempt to
agree in good faith upon a single appraiser not later than seven (7) days after
the Landlord receives notice of Tenant's rejection of Landlord's proposed Market
Rent ("Tenant's Rejection Notice"), which date of receipt shall be within
fifteen (15) days after

                                       7
<PAGE>

Landlord's delivery of Landlord's Rent Notice. If Landlord and Tenant are unable
to agree upon a single appraiser within such time period, then Landlord and
Tenant shall each appoint one appraiser not later than fifteen (15) days after
Landlord's receipt of Tenant's Rejection Notice. Within five (5) days
thereafter, the two appointed appraisers shall appoint a third appraiser.
Landlord and Tenant shall instruct the appraiser(s) to complete the
determination of the Market Rent not later than fifteen (15) days after all
appraisers have been appointed. If the two appraisers are unable to select the
third appraiser within such five (5) day period, then Landlord and Tenant shall
be entitled to apply to the MAI for the appointment of a third appraiser.

                           (ii) If either Landlord or Tenant fails to appoint
its appraiser within the prescribed time period, the single appraiser appointed
shall determine the Market Rent of the Premises for the first year of the Second
Option Term. If both parties fail to appoint appraisers within the prescribed
time periods, then the first appraiser thereafter selected by a party shall
determine the Market Rent of the Premises for the first year of the Second
Option Term.

                           (iii) Landlord and Tenant shall each bear the cost of
its own appraiser and the parties shall share equally the cost of the single or
third appraiser, if applicable. All appraisers so designated herein shall have
at least five (5) years' experience in the appraisal of similar office buildings
in the San Diego area and shall be members of professional organizations such as
MAI or equivalent.

                           (iv) If a single appraiser is chosen, then such
appraiser shall determine the Market Rent of the Premises for the first year of
the Second Option Term. Otherwise, the Market Rent of the Premises for the first
year of the Second Option Term shall be the arithmetic average of two (2) of the
three (3) appraisals which are closest in amount, and the third appraisal shall
be disregarded. Notwithstanding anything else contained herein, the Market Rent
as so determined shall not be less than the Basic Annual Rent payable during the
year preceding the Second Option Term.

4.2 ADDITIONAL RENT. All charges required to be paid by Tenant hereunder,
including without limitation, payments for Operating Expenses and any other
amounts payable under this Lease, shall be considered additional rent for the
purposes of this Lease ("Additional Rent"), and Tenant shall pay Additional Rent
as provided in Article 6.05. "Rent" shall mean Base Rent and Additional Rent.

4.3 ESCALATION. Annual Base Rent for the second year of the Second Option Term
and each and every succeeding year thereafter during the Second Option Term
shall be increased by an amount equal to three percent (3%) of the Annual Base
Rent payable for the preceding year.

4.4 LATE PAYMENT. If any installment of Rent is not paid promptly on the first
of the month or otherwise when due, the unpaid amounts shall bear interest at
the interest rate set forth in Section 12.02(e) from the date due to the date of
payment. In addition, Tenant acknowledges that the late payment of any
installment of Rent will cause Landlord to incur certain costs and expenses not
contemplated under this Lease, the exact amount of which are extremely difficult
or impractical to fix. These costs and expenses will include, without
limitation, administrative and collection costs and processing and accounting
expenses. Therefore, if any installment of Rent is not received by Landlord from
Tenant when the installment is due, Tenant shall pay to Landlord on demand a
charge for administration, collection and accounting expenses equal to five
percent (5%) of the amount of such delinquent amounts due ("Late Charge") in
addition to the installment of Rent then owing with interest at the interest
rate set forth in Section 12.02(e), regardless of whether or not a notice of
default or notice of termination has been given by Landlord; provided, however,
Tenant shall not be required to pay such Late Charge if such late payment is the
first late payment of Rent by Tenant in the preceding twelve (12) months and the
installment of Rent is paid not more than five (5) days after the date same is
due.. Landlord and Tenant agree that the late payment charge represents a
reasonable estimate of Landlord's costs and expenses and is fair compensation to
Landlord for its loss suffered by Tenant's nonpayment of any amounts when due
and payable pursuant to this Lease. This provision shall not relieve Tenant from
payment of Rent at the time and in the manner herein specified.

                                       8

4.5 SECURITY DEPOSIT. Upon executing this Lease, Tenant shall deposit with
Landlord a Security Deposit in the amount of the first month's Base Rent. The
Security Deposit shall secure Tenant's obligations under this Lease to pay rent
and other monetary amounts, to maintain the Premises and repair damages thereto,
to surrender the Premises to Landlord in clean and sanitary condition and repair
upon termination of this Lease as required pursuant to Section 18.15 below and
to discharge Tenant's other obligations hereunder. Landlord may use and
commingle the Security Deposit with other funds of Landlord. If Tenant fails to
perform Tenant's obligations hereunder, Landlord may, but without any obligation
to do so, apply all or any portion of the Security Deposit towards fulfillment
of Tenant's unperformed obligations. If Landlord does so apply any portion of
the Security Deposit, Tenant, shall immediately pay Landlord a sufficient amount
in cash to restore the Security Deposit to the full original amount. In the
event that Landlord shall expend the same in order to cure Tenant's default
hereunder, Tenant's failure to forthwith remit to Landlord a sufficient amount
in cash to restore the Security Deposit to the original sum deposited within ten
(10) days after Tenant's receipt of notice from Landlord that such amounts have
been so expended shall constitute an Event of Default. The Security Deposit
shall be held by Landlord without liability for interest on the same. Upon
termination of this Lease, if Tenant has then performed all of Tenant's
obligations hereunder, Landlord shall return the Security Deposit to Tenant. If
Landlord sells or otherwise transfers Landlord's rights or interest under this
Lease, Landlord may deliver the Security Deposit to the transferee, whereupon
Landlord shall be released from any further liability to Tenant with respect to
the Security Deposit.


5 . INSURANCE

5.1 ALL RISK COVERAGE. At all times during the Term, Landlord shall procure and
maintain in full force and effect with respect to the Project, a policy or
policies of all risk insurance (including sprinkler, vandalism and malicious
mischief coverage, and any other endorsements required by the holder of any fee
or leasehold mortgage) in an amount equal to one hundred percent (100%) of the
full replacement value (replacement cost new, including debris removal, and
demolition) thereof and any other insurance Landlord reasonably deems necessary,
including, but not limited to, boiler and machinery insurance. If the annual
premiums charged Landlord for such casualty insurance exceed the standard
premium rates because the nature of Tenant's operations results in increased
exposure, then Tenant shall, upon receipt of appropriate premium invoices,
reimburse Landlord for such increased amount. Landlord shall also keep and
maintain, by endorsement to its all risk insurance or by a separate policy ,
rental abatement insurance insuring against abatement or loss of Rent in case of
fire or other casualty insured against by a standard "all risk" policy, in an
amount at least equal to the amount of the Rent payable by Tenant during one (1)
year next ensuing, as reasonably determined by Landlord. At all times during the
Term, Tenant shall procure, pay for and maintain in full force and effect a
similar policy of insurance, naming Landlord and Managing Agent as an additional
insured with respect to property of every description and kind owned by Tenant
upon the Premises or the Building, or for which Tenant is legally liable,
including, without limitation, trade fixtures, furniture, equipment and other
personal property, and all tenant improvements owned or installed by or on
behalf of Tenant (but not with respect to those owned constructed by and owned
by Landlord and defined in the Work Letter as Tenant's Improvement Work)
insuring one hundred percent (100%) of the full replacement value of said
property and tenant improvements. Any policy proceeds shall be used for the
repair and replacement of the property damaged or destroyed unless this Lease
shall cease and terminate under the provisions on excessive damage or
destruction set forth in Section 10.04 below. Landlord shall cause the original
Tenant and any Affiliate Transferee to be named as an additional insured under
the all-risk policy of insurance to be maintained by Landlord pursuant to this
Section 5.01, except if such coverage becomes unavailable on commercially
reasonable terms.

5.2 LIABILITY COVERAGE. Within fifteen (15) days after the execution of this
Lease, Tenant shall provide Landlord with certificates of insurance for all of
Tenant's insurance policies required hereunder so that Landlord may determine
whether Tenant's insurance policies are in such forms, amounts and are written
by such insurance companies as required by Landlord. Tenant shall, at its own
cost and expense, keep and maintain in full force during the Term, a policy or
policies of broad form

                                       9

<PAGE>

commercial general liability insurance with and cross-liability endorsements
(insuring Tenant's indemnification obligations under this Lease, including
Article 5.09 hereof) written by an insurance company reasonably approved by
Landlord in the form customary to the locality, insuring Tenant's activities
with respect to the Premises and/or Building against loss, damage or liability
for personal and bodily injury (including wrongful death) of any person and loss
or damage to property occurring in, upon or about the Premises covering personal
and bodily injury in the amounts of not less than Three Million Dollars
($3,000,000) per person and Three Million Dollars ($3,000,000) per occurrence
and covering property damage in the amount of not less than One Million Dollars
($1,000,000) per occurrence. These limits may be satisfied by a basic policy and
an umbrella policy. Such insurance shall be with insurance companies with a Best
rating classification of not less than XI and a financial rating classification
not less than XII and approved to do business in California. Such insurance
shall have a deductible of no greater than Five Thousand Dollars ($5,000).
Tenant's obligations to carry the insurance set forth herein may be satisfied by
coverage under a so-called blanket policy of broad form commercial general
liability insurance with the same endorsements and coverage for the Premises as
described above, as well as coverage of other premises and properties of Tenant,
or in which Tenant has some interest; provided, however, that Landlord and
Managing Agent shall be named as an additional insured, the coverage afforded
Landlord shall not be reduced or diminished, and the requirements set forth in
this Lease are otherwise satisfied.

5.3 WORKER'S COMPENSATION INSURANCE. Tenant shall, at its own cost and
expense, keep and maintain in full force during the Term, a policy or
policies of worker's compensation insurance, in statutory amounts and limits,
and employer's liability insurance with limits as follows: bodily injury each
accident in the amount of not less than One Million Dollars ($1,000,000),
bodily injury/disease each employee in an amount not less than One Million
Dollars ($1,000,000), and a bodily injury/disease policy limit of not less
than One Million Dollars ($1,000,000).

5.4 BUSINESS INTERRUPTION INSURANCE. Tenant shall, at its own cost and expense,
keep and maintain in full force during the Term (a) such policy or policies of
business interruption insurance, as Tenant may deem necessary or appropriate,
insuring that the monthly installments of Rent shall be paid to Landlord for a
period of not less than one (1) year if the Premises are destroyed or
inaccessible by a risk not insured against by a standard "all risk" form policy
Landlord is required to maintain pursuant to the provisions of Section 5.01
above, and (b) such other policies of insurance insuring such other risks as
Tenant may deem necessary or appropriate.

5.5 INSURANCE CERTIFICATES. Tenant shall furnish to Landlord, no more than ten
(10) days prior to the earlier of Tenant's occupancy of the Premises (as
permitted by Section ) or the Term Commencement Date of this Lease and
thereafter no more than thirty (30) days prior to the expiration of each such
policy, a certificate of insurance issued by the insurance carrier of each
policy of insurance carried by Tenant pursuant hereto. Said certificates shall
expressly provide that such policies shall not be calculable or subject to
reduction of coverage or otherwise be subject to modification except after
thirty (30) days' prior written notice to the parties named as additional
insureds in this Article 5. Landlord, its successors and assigns, and any
nominee of Landlord holding any interest in the Premises, including without
limitation, any ground lessor and the holder of any fee or leasehold mortgage,
shall be named as additional insureds under each such policy of insurance
maintained by Tenant pursuant to this Lease.

5.6 TENANT'S FAILURE. If Tenant fails to maintain any insurance required in this
Lease, Tenant shall be liable for any loss or cost resulting from said failure.
Notwithstanding the foregoing, Landlord may at Landlord's sole discretion, but
shall not be required to, procure said insurance on Tenant's behalf and charge
Tenant the premium for such policies. This Section 5.06 shall not be deemed to
be a waiver of any of Landlord's rights and remedies under any other section of
this Lease.

5.7 WAIVER OF SUBROGATION. Any policy or policies of fire, extended coverage or
similar casualty insurance, which either party obtains in connection with the
Premises, or Tenant's personal property therein, shall, to the extent the same
can be obtained without unreasonable expense, include a clause or endorsement
denying the insurer any rights of subrogation against the other party to the
extent

                                       10
<PAGE>

rights have been waived by the insured prior to the occurrence of injury or
loss. Landlord and Tenant waive any rights of recovery against the other for
injury or loss due to hazards covered by insurance containing such a waiver of
subrogation clause or endorsement to the extent of the injury or loss covered
thereby.

5.8 TENANT'S PROPERTY AND FIXTURES. Tenant shall assume the risk of damage to
any furniture, equipment, machinery, goods, supplies or fixtures which are or
remain the property of Tenant or as to which Tenant retains the right of removal
from the Premises.

5.9 INDEMNIFICATION.
                  (a) To the fullest extent permitted by law, Tenant covenants
with Landlord that Landlord, Landlord's agents and employees shall not be liable
for any damage or liability of any kind or for any injury to or death of
persons, or damage to property of Tenant or any other person occurring from any
cause whatsoever related to the use, improvement, occupancy or enjoyment of the
Premises by Tenant or any person thereon or holding under Tenant, unless such
damage, liability, injury or death results from the gross negligence or willful
misconduct of Landlord or its agents. Tenant shall indemnify protect, defend and
hold Landlord and its members, officers, employees, agents, servants,
concessionaires, licensees, contractor or invitees ("Landlord Parties"), the
Premises, Building, Project, Lot and Landlord's related property, harmless from
and against (i) any and all liability, fines, penalties, losses, damages, costs
and expenses, demands, causes of action, claims or judgments (collectively,
"Claims") arising from or growing out of any injury to any person or persons or
any damage to any property as a result of any accident or other occurrence
during the Term occasioned in any way as a result of Tenant's or Tenant's
Parties' negligence or willful misconduct in the use, maintenance, occupation or
operation of the Premises during the Term, (ii) all liens, claims and demands
related to the Tenant's use of the Premises and its facilities during the Term,
or any repairs, alterations or improvements which Tenant may make or cause to be
made upon the Premises, and (iii) from and against all legal costs and charges,
including attorneys' fees, incurred in and about any of such matters and the
defense of any action arising out of the same or in discharging the Building,
Project, Lot and Landlord's related property or any part thereof from any and
all liens, charges or judgments which may accrue or be placed thereon by reason
of any act or omission of the Tenant; provided, however, that Tenant shall not
be required to indemnify Landlord for any damage or injury arising as a result
of the gross negligence or willful misconduct of Landlord, Landlord's agents or
employees. This indemnity shall survive the termination of this Lease for four
(4) years.
                  (b) Landlord shall indemnify, defend and hold harmless Tenant
and its officers, employees, agents, servants, subtenants, concessionaires,
licensees, contractor or invitees ("Tenant Parties") from and against all Claims
for damage to property outside the Premises to the extent that such Claims
result from the gross negligence or willful misconduct of Landlord and its
agents and employees in connection with their activities in, on or about the
Project or the Building, except to the extent that such Claim (i) is for damage
to Tenant's Improvements or Tenant's personal property, fixtures, furniture and
equipment in the Premises and is covered by insurance that Tenant is required to
obtain under this Lease (or would have been covered had Tenant carried the
insurance required under this Lease) or (ii) results from the negligent acts,
omissions or willful misconduct of Tenant Parties. This indemnity shall survive
the termination of this Lease for four (4) years.

5.10 EARTHQUAKE AND FLOOD INSURANCE. In addition to any other insurance policies
carried by Landlord in connection with the Project, Landlord may elect to
procure and maintain in full force and effect during the Term, with respect to
the Project, a policy of earthquake/volcanic action and flood and/or surface
water insurance, including rental value insurance against abatement or loss of
rent in the case of damage or loss covered under such earthquake/volcanic and
flood and/or surface water insurance, in an amount up to one hundred percent
(100%) of the full insurance replacement value (including debris removal and
demolition) of the Project improvements.

5.11 OTHER TENANT INSURANCE COVERAGE. Tenant shall, at Tenant's own expense,
procure and maintain any other and further insurance coverages that Landlord or
Landlord's lender may

                                       11

<PAGE>

reasonably require. Tenant shall not, however, be required to procure or
maintain other and further coverages that are beyond those typically maintained
by similarly situated tenants leasing reasonably similar amounts and types of
space for similar use in comparable buildings in the same submarket.

6 . OPERATING EXPENSES

6.1 TENANT'S SHARE. (a) Tenant's share of Building Operating Expenses
("Tenant's Building Share") is hereby mutually agreed to be that percentage
set forth in the Basic Lease Information, subject however, to adjustment as
set forth in Section 1.05 Tenant shall pay as Additional Rent Tenant's
Building Share of Building Operating Expenses for any calendar year after the
Base Calendar Year to the extent that Building Operating Expenses for such
calendar year exceed the Building Operating Expenses for the Base Calendar
Year .

                  (b) Tenant's share of Project Operating Expenses ("Tenant's
Project Share") is hereby mutually agreed to be that percentage set forth in the
Basic Lease Information, subject however, to adjustment as set forth in Section
1.05. Tenant shall pay as Additional Rent Tenant's Project Share of Project
Operating Expenses for any calendar year after the Base Calendar Year to the
extent that Project Operating Expenses for such calendar year exceed the Project
Operating Expenses for the Base Calendar Year.

                  (c) For the purposes of this Article 6 and determining
Tenant's Share of Building Operating Expenses and Tenant's Share of Project
Operating Expenses, Landlord and Tenant hereby agree that the Operating Expenses
for the Base Calendar Year shall be the greater of (A) the amount of Five
Dollars and Sixty Five Cents ($5.65) per square feet of Rentable Area in the
Premises, as increased by an amount determined by multiplying the amount of Five
Dollars and Sixty Five Cents ($5.65) per square feet of Rentable Area in the
Premises by the increase, if any, in the Index (as hereinafter defined) from the
date of this Lease through December 31, 2002, being the amount budgeted by
Landlord for Operating Expenses during the Base Calendar Year (the "Budgeted
Operating Expenses"); or (B) the sum of the actual Operating Expenses incurred
by Landlord during the Base Calendar Year and an amount equal to Twenty-five
Cents ($.25) per square foot of Rentable Area in the Premises (the "Operating
Expense Buffer"). Within sixty (60) days after the date of this Lease, Landlord
shall deliver to Tenant for Tenant's approval a revised budget for Operating
Expenses for the Base Calendar Year, which shall allocate in a reasonable manner
the foregoing expenses between Building Operating Expense and Project Operating
Expenses. Tenant shall not unreasonably withhold or delay Tenant's approval of
Landlord's budget. If Tenant disapproves Landlord's revised budget, then Tenant
shall notify Landlord of the reasons therefor and Landlord and Tenant shall
thereafter negotiate reasonably to agree upon a revised budget. If they are
unable to so agree within sixty (60) days after Landlord delivers its proposed
revised budget to Tenant, then the dispute shall be resolved in accordance with
the Real Estate Industry Arbitration Rules of the American Arbitration
Association. After Landlord and Tenant agree on (or arbitration establishes) a
revised budget that allocates Budgeted Operating Expenses between Building
Operating Expenses and Project Operating Expenses:

                           (i) Building Operating Expenses for the Base Calendar
         Year shall be the greater of (x) the amount of the Budgeted Operating
         Expenses allocated to Building Operating Expenses, or (y) the sum of
         the actual Building Operating Expenses incurred by Landlord during the
         Base Calendar Year and an amount equal to the portion of the Operating
         Expense Buffer that is allocated to the Building Operating Expenses;
         and

                           (ii) Project Operating Expenses for the Base Calendar
         Year shall be the greater of (x) the amount of the Budgeted Operating
         Expenses allocated to Project Operating Expenses, or (y) the sum of the
         actual Project Operating Expenses incurred by Landlord during the base
         Calendar Year and an amount equal to the portion of the Operating
         Expense Buffer that is allocated to the Project Operating Expenses.

                                       12


<PAGE>

For purposes of the foregoing, the Operating Expense Buffer shall be allocated
between Building Operating Expenses and Project Operating Expenses in the same
proportion that actual Building Operating Expenses for the Base Calendar Year
bears to actual Project Operating Expenses for the Base Calendar Year. Tenant's
Share of Building Operating Expenses and Tenant's Share of Project Operating
Expenses payable pursuant to subsections (a) and (b) above shall thereafter be
determined based on the approved revised budget submitted by Landlord. For the
purposes of this Section 6.01, the term "Index" shall mean the Department of
Labor, Bureau of Labor Statistics, Consumer Price Index, Subgroup "Urban Wage
Earners and Clerical Workers (Revised)", Los Angeles - Long Beach - Anaheim -
Riverside Metropolitan Area (1982-84 = 100).

terminate within ten (10) days of the date of the Repair Period Notice, this
Lease shall remain in full force and effect and Landlord shall diligently repair
and restore the damage as soon as reasonably possible.

10.5 UNINSURED CASUALTIES AND OTHER CONDITIONS/OPTION TO TERMINATE.
Notwithstanding anything contained herein to the contrary, (a) in the event of
damage to or destruction of all or any portion of the Building, which is not
fully covered by the insurance proceeds received by Landlord under the insurance
policies required under Article 5 hereinabove (provided that any deductible
shall be ignored in determining whether any damage or destruction is covered),
Landlord may terminate this Lease by written notice to Tenant, given within
forty-five (45) days after the date of notice to Landlord that said

                                       24
<PAGE>

damage or destruction is not so covered; (b) in the event of
damage to or destruction of all or any portion of the Building, which is due to
the acts or omissions of Tenant, its agents, employees or contractors, Landlord
may terminate this Lease by written notice to Tenant, given within forty-five
(45) days after the date of a Landlord's determination that said damage or
destruction was due to the acts or omissions of Tenant, its agents, employees or
contractors; or (c) in the event sufficient proceeds of insurance maintained by
Landlord pursuant to the terms of this Lease are unavailable to Landlord to
reconstruct and restore the Premises in the event of damage to or destruction of
all or any portion of the Building because they have been applied by any lender
against payment of an existing loan on the Project or Building, Landlord may
terminate this Lease by written notice to Tenant, given within forty-five (45)
days after the date of notice to Landlord that any such lender intends to apply
any of the insurance proceeds against payment of an existing loan on the Project
or Building. If Landlord does not elect to terminate this Lease, the Lease shall
remain in full force and effect and Landlord shall commence reconstruction and
restoration of Landlord's Work and Tenant's Improvement Work in the Premises as
described in Exhibit D and shall diligently repair or rebuild Landlord's Work to
substantially the condition in which it existed immediately prior to such damage
or destruction.

10.6 WAIVER. With respect to any destruction which Landlord is obligated to
repair or may elect to repair under the terms of this Article 10, Tenant hereby
waives all rights to terminate this Lease pursuant to rights otherwise presently
or hereafter accorded by law to tenants, except as expressly otherwise provided
herein.

11. EMINENT DOMAIN

11.1 TOTAL CONDEMNATION. If the whole of the Premises is acquired or condemned
by eminent domain, inversely condemned or sold in lieu of condemnation, for any
public or quasi-public use or purpose ("Condemned"), then the Term shall
terminate as of the date of title vesting in such proceeding, and Rent shall be
adjusted as of the date of such termination. Tenant shall immediately notify
Landlord of any such occurrence.

11.2 PARTIAL CONDEMNATION. If any part of the Premises is partially Condemned,
and such partial condemnation renders the Premises unusable for the business of
the Tenant, as reasonably determined; or in the event a substantial portion of
the Building is Condemned, as reasonably determined, then the Term shall
terminate as of the date of title vesting in such proceeding and Rent shall be
adjusted to the date of termination. If such condemnation is not sufficiently
extensive to render the Premises unusable for the business of Tenant, as
reasonably determined, or less than a substantial portion of the Building is
Condemned, then Landlord shall promptly restore the Premises to a condition
comparable to its condition immediately prior to such condemnation less 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 the Base Rent
shall be appropriately reduced as reasonably determined by Landlord.

11.3 LANDLORD'S AWARD. If the Premises are wholly or partially Condemned, then,
subject to the provision of Article 11.04 Landlord shall be entitled to the
entire award paid for such condemnation, and Tenant waives any right or claim to
any part thereof from Landlord or the condemning authority.

11.4 TENANT'S AWARD. Tenant shall have the right to claim and recover from the
condemning authority, but not from Landlord, such compensation as may be
separately awarded or recoverable by Tenant in Tenant's own right on account of
any and all costs or loss incurred by Tenant including, without limitation,
removing Tenant's merchandise, furniture, fixtures, leasehold improvements and
equipment to a new location.

11.5 TEMPORARY CONDEMNATION. If the whole or any part of the Premises
shall be Condemned for any temporary public or quasi-public use or purpose, this
Lease shall remain in effect and Tenant shall be entitled to receive for itself
such portion or portions of any award made for such use with respect to the
period of the taking which is within the Term. If a temporary condemnation
remains in force at the expiration or earlier termination of this Lease, Tenant
shall pay to Landlord a sum equal to the reasonable cost of performing any
obligations required of Tenant by this Lease with respect to the

                                       25
<PAGE>

surrender of the Premises, including without limitation, repairs and
maintenance, and upon such payment such obligations shall be deemed satisfied.
If a temporary condemnation is for an established period which extends beyond
the Term, the Lease shall terminate as of the date of occupancy by the
condemning authority, and the damages shall be as provided in Sections 11.03 and
11.04 hereinabove and Rent shall be adjusted to the date of occupancy.

11.6 NOTICE AND EXECUTION. Landlord shall, immediately upon service of process
in connection with any condemnation or potential condemnation, give Tenant
notice in writing thereof. Tenant shall immediately execute and deliver to the
Landlord all instruments that may be required to effectuate the provisions of
this Article.

12 . DEFAULT

completion;
                  (c) ASSIGNMENT. A general assignment by Tenant for the benefit

Tenant having notice of such contamination, or if more than three (3) days is
reasonably required to remedy such contamination, any failure of Tenant to
commence to remedy such contamination within such three (3) day period and to
diligently prosecute such remedy to completion.

12.2 LANDLORD'S REMEDIES.

                  (a) ABANDONMENT. If Tenant vacates or abandons the Premises
and an uncured Event of Default exists, this Lease shall continue in effect,
Landlord shall not be deemed to have terminated this Lease other than by written
notice of termination from Landlord, and Landlord shall have all of the remedies
of a landlord provided by Section 1951.4 of the Civil Code of the State of
California. At

                                       26

<PAGE>

any time subsequent to vacation or abandonment of the Premises by Tenant,
Landlord may give notice of termination and shall thereafter have all of the
rights hereinafter set forth.

                  (b) TERMINATION. Following the occurrence of any Event of
Default, Landlord shall have the right, so long as the default continues, to
terminate this Lease by written notice to Tenant setting forth: (i) the default;
(ii) the requirements to cure it; and (iii) a demand for possession, which shall
be effective three (3) days after it is given or upon expiration of the times
specified in Section 12.01 hereinabove, whichever is later.

                  (c) POSSESSION. Following termination under subsection (b),
without prejudice to any other remedies Landlord may have by reason of Tenant's
default or of such termination, Landlord may then or at anytime thereafter, (i)
peaceably re-enter the Premises, or any part thereof, upon voluntary surrender
by Tenant or expel or remove Tenant therefrom and any other persons occupying
them, using such legal proceedings as are then available; (ii) repossess and
enjoy the Premises, or relet the Premises or any part thereof for such term or
terms (which may be for a term extending beyond the Term) at such rental or
rentals and upon such other terms and conditions as Landlord in its sole
discretion shall determine, with the right to make reasonable alterations and
repairs to the Premises; and (iii) remove all personal property therefrom and,
at Landlord's option, retain all or any of such personal property (and title
thereto shall thereupon vest in Landlord without compensation to Tenant) or
dispose of all or any of such personal property, in any manner, without
compensation to Tenant. In the event Landlord removes all or any of Tenant's
personal property pursuant to the foregoing provisions, Tenant shall pay to
Landlord, upon demand, the actual expense of such removal and disposition and
the cost of repairing any damage to the Premises resulting from such removal.

                  (d) RECOVERY. Following termination under subsection (b),
Landlord shall have all the rights and remedies of a landlord provided by
Section 1951.2 of the Civil Code of the State of California. The amount of
damages which Landlord may recover following termination under subsection (b)
shall include: (i) the worth at the time of the award of the unpaid rent and
other amounts which had been earned at the time of termination; (ii) the worth
at the time of the award of the amount by which the unpaid rent which would have
been earned after termination until the time of the award exceeds the amount of
such rental loss that Tenant proves could have been reasonably avoided; (iii)
the worth at the time of the award of the amount by which the unpaid Rent for
the balance of the Term after the time of award exceeds the amount of rental
loss Tenant proves could be reasonably avoided; and (iv) any other amount
necessary to compensate Landlord for all detriment proximately caused by
Tenant's failure to perform its obligations under this Lease. The "worth at the
time of the award" of the amount referred to in (i) and (ii) above shall be
computed by allowing interest thereon at the Default Rate (as set forth below).
The "worth at the time of the award" of the amount referred to in (iii) above
shall be computed by discounting such amount at the Default Rate (as set forth
below).
                  (e) ADDITIONAL REMEDIES. In addition to the foregoing
remedies, Landlord shall, so long as this Lease is not terminated, have the
right to remedy any default of Tenant to maintain or improve the Premises
without terminating this Lease, to incur expenses on behalf of Tenant in seeking
a new subtenant, or 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 lower of
the prime rate of interest at the time of said default charged by Wells Fargo
Bank N.A. plus three percent (3%) or the maximum lawful rate (the "Default
Rate").
                  (f) OTHER. If Tenant causes or threatens to cause a breach of
any of the covenants, agreements, terms or conditions contained in this Lease,
Landlord shall be entitled to retain all sums held by Landlord, by any trustee
or in any account provided for herein, to enjoin such breach or threatened
breach, and to invoke any right and remedy allowed at law or in equity or by
statute or otherwise as though re-entry, summary proceedings and other remedies
were not provided for in this Lease. As used in this Article, the term
"threatens" is limited to delivery to Landlord of a written statement by Tenant
indicating Tenant's intent to cause a breach or Tenant's anticipation of its
uncured default in the performance of, any of the covenants, agreements, terms
or conditions contained in this Lease.

                                       27
<PAGE>

                  (g) CUMULATIVE. Each right and remedy of Landlord provided for
in this Lease shall be cumulative and shall be in addition to every other right
or remedy provided for in this Lease or now or hereafter existing at law or in
equity or by statute or otherwise. The exercise or beginning of the exercise by
Landlord of any one or more of the rights or remedies provided for in this
Lease, or now or hereafter existing at law or in equity or by statute or
otherwise, shall not preclude the simultaneous or later exercise by Landlord of
any or all other rights or remedies provided for in this Lease or now or
hereafter existing at law or in equity or by statute or otherwise.

                  (h) NO WAIVER. No failure by Landlord to insist upon the
strict performance of any term hereof or to exercise any right or remedy
consequent upon a breach thereof, and no acceptance of full or partial payment
of Rent during the continuance of any such breach shall constitute a waiver of
any such breach or of any such term. Efforts by Landlord to mitigate the damages
caused by Tenant's breach of this Lease shall not be construed to be a waiver of
Landlord's right to recover damages under this Article 12. Nothing in this
Article 12 affects the right of Landlord to indemnification by Tenant in
accordance with Article hereinabove for liability arising prior to the
termination of this Lease for personal injuries or property damage.

13 . ASSIGNMENT AND SUBLETTING

13.1 ASSIGNMENT AND SUBLETTING; PROHIBITION. Except as hereinafter provided
in this Section 13.01, Tenant shall not assign, mortgage, pledge, hypothecate
or otherwise transfer, this Lease, in whole or in part, or any interest
therein, nor sublet or permit occupancy by any party other than Tenant of all
or any part of the Premises (each of the foregoing is hereinafter sometimes
referred to as a "Transfer"), without the prior written consent of Landlord
in each instance, which may not be unreasonably withheld or delayed;
provided, however, Tenant acknowledges and agrees that it shall not be
unreasonable for Landlord to take into consideration in connection with a
proposed Transfer such factors as (a) the impact on parking in the Project;
(b) the impact of possible noise or odors generated by the proposed use; and
(c) the image of the project in the community. As material consideration for
this Lease, Tenant hereby agrees to provide the following written materials
to Landlord regarding any proposed Transfer and the proposed transferee (the
"Transferee") for Landlord's approval: (i) the proposed Transfer agreement to
Landlord for Landlord's approval; (ii) financial statements of the Transferee
for the three (3) years prior to the proposed Transfer, which financial
statements shall be audited if the Transfer contemplates the release of
Tenant from any of its obligations under this Lease, or otherwise audited, if
available, or certified by the transferee as being true and correct and
prepared in accordance with generally acceptable accounting principles,
consistently applied; (iii) detailed summaries of the Transferee's business
operation; (iv) a detailed credit report of the Transferee; and (v) banking
references for the Transferee. Landlord shall have the right to review the
written material submitted by Tenant regarding such Transfer for a period of
fifteen (15) business days following Landlord's receipt of such material to
consent or decline to consent to such Transfer. No Transfer by Tenant shall
relieve Tenant of any obligation under this Lease, including Tenant's
obligation to pay Base Rent and Additional Rent hereunder. Any purported
Transfer contrary to the provisions hereof without Landlord's consent
("Unauthorized Transfer") shall be void. The consent by Landlord to any
Transfer shall not constitute a waiver of the necessity for such consent to
any subsequent Transfer. As Additional Rent hereunder, Tenant shall reimburse
Landlord for actual legal and other expenses incurred by Landlord in
connection with any request by Tenant for Landlord's consent to the Transfer
up to Two Thousand Dollars ($2,000) per proposed Transfer. Such amount shall
be reimbursed by Tenant to Landlord within ten (10) days following the
submission to Tenant of a copy of the written invoice from Landlord's counsel
itemizing such costs and fees payable by Landlord with respect to any request
by Tenant for Landlord's consent to such a Transfer, whether or not Landlord
ultimately approves such Transfer. Tenant shall have the right, subject to
the foregoing obligations to deliver the relevant written materials to
Landlord, but without Landlord's consent, to enter into an assignment of this
Lease or a sublease of the Premises to any subsidiary corporation of Tenant,
Tenant's parent corporation, to any corporation or other entity that
controls, is controlled by or under common control with Tenant or to any
corporation, partnership or other entity succeeding to substantially all of
the assets of Tenant as a result of a consolidation or merger, or to

                                       28
<PAGE>


a corporation, partnership or other entity to which all or substantially all
of the assets of Tenant have been sold ("Affiliate Transferee"), provided any
Affiliate Transferee that is an assignee (but not any sublessee) executes an
instrument in form and content reasonably acceptable to Landlord assuming all
of Tenant's obligation under the Lease. If the net worth of such Transferee,
as of the date of the proposed Transfer, is equal to or greater than the net
worth of the initial Tenant measured as of the Lease Date or the date of the
proposed Transfer, whichever net worth is greater, then Landlord agrees that
Landlord will execute a form of release providing that Tenant shall be
released from the further performance of covenants on the part of Tenant
herein contained, and from any and all further liability, obligations, costs
and expenses, demands, causes of action, claims or judgments arising from or
growing out of, or connected with this Lease after the effective date of such
release, other than those arising out of or related to Tenant's obligations
under the Lease prior to the date of the release. The effective date of such
release shall be the date Tenant assigns its interest in this Lease to the
Tenant's assignee.

13.2 BONUS RENTAL. If for any assignment or sublease other than to an Affiliate
Transferee, Tenant receives rent or other consideration, either initially or
over the term of the assignment or sublease, in excess of the Rent called for
hereunder, or in case of the sublease of a portion of the Premises, in excess of
such Rent fairly allocable to such portion, after appropriate adjustments to
assure that all other payments called for hereunder are appropriately taken into
account, Tenant shall pay to Landlord promptly after its receipt by Tenant, as
Additional Rent hereunder, fifty percent (50%) of the excess of each such
payment of rent or other consideration received by Tenant, after the recovery by
Tenant of Tenant's reasonable actual costs of assigning the Lease or subletting
the Premises, including real estate commissions, tenant improvements, other
normal leasing costs and attorney fees.

13.3 SCOPE. The prohibition against Unauthorized Transfers contained in this
Article shall be construed to include a prohibition against any Transfer by
operation of law. If this Lease or any interest therein be assigned, or if the
underlying beneficial interest of Tenant is transferred, or if the Premises or
any part thereof be sublet or occupied by anybody other than Tenant, Landlord
may 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 immediately preceding paragraph,
but no such assignment, subletting, occupancy or collection shall be deemed a
waiver of this covenant, or the acceptance of the assignee, subtenant or
occupant as tenant, or a release of Tenant from the further performance by
Tenant of covenants on the part of Tenant herein contained. Except as set forth
in Section 13.01, no assignment or subletting shall affect the continuing
primary liability of Tenant (which, following assignment, shall be joint and
several with the assignee), and Tenant shall not be released from performing any
of the terms, covenants and conditions of this Lease.

13.4 WAIVER. Notwithstanding any Transfer, or any indulgences, waivers or
extensions of time granted by Landlord to any Transferee, or failure by Landlord
to take action against any Transferee, Tenant waives notice of any default of
any Transferee and agrees that Landlord may, at its option, proceed against
Tenant without having taken action against or joined such Transferee, except
that Tenant shall have the benefit of any indulgences, waivers and extensions of
time granted to any such Transferee. Tenant further waives monetary damages, of
whatever kind or nature, from Landlord as a result of, or in any way related to
any proposed Transfer, whether Landlord consented to such Transfer or withholds
its consent to such Transfer.

13.5 RELEASE. Whenever Landlord conveys its interest in the Project and/or
Building, Landlord shall be automatically released from the further performance
of covenants on the part of Landlord herein contained, and from any and all
further liability, obligations, costs and expenses, demands, causes of action,
claims or judgments arising from or growing out of, or connected with this Lease
after the effective date of said release. The effective date of said release
shall be the date Landlord transfers title of the Project to the new owner and
the new owner assumes Landlord's obligations under this Lease in writing. If
requested, Tenant shall execute a form of release and such other documentation
as may be required to further effect the provisions of this Section 13.05.

                                       29
<PAGE>

13.6 RECAPTURE OF PREMISES. In the event Tenant proposes to enter into a
Transfer, other than a Transfer with to an Affiliate Transferee, which
Transfer, when taken together with all previous transfers other than to
Affiliate Transferees, relates to more than forty nine percent (49%) of the
rentable square feet of the Premises (the "Subject Space") and is for the
entire then remaining balance of the Term, or substantially all of the
remaining balance of the Term, then Tenant shall notify Landlord in writing
(the "Availability Notice") if Tenant wishes to Transfer the Subject Space.
Landlord shall have the option, by written notice to Tenant (the "Recapture
Notice") within ten (10) days after receiving any Availability Notice, to
recapture the Subject Space as described below. A timely Recapture Notice
terminates this Lease and Tenant's obligations regarding the Subject Space
for the remaining term of the Lease and as of the date sixty (60) days after
Landlord delivers the Recapture Notice to Tenant. If Landlord declines to or
fails timely to elect to recapture the Subject Space, Landlord shall have no
further right under this Section 13.06 to the Subject Space unless Tenant
fails to Transfer the Subject Space within one hundred fifty (150) days after
Landlord receives the Availability Notice or it becomes available again after
Transfer by Tenant. To determine the new Base Rent under the Lease if
Landlord recaptures the Subject Space, the original Base Rent under the Lease
shall be multiplied by a fraction, the numerator of which is the square feet
of Rentable Area of the Premises retained by Tenant after Landlord's
recapture and the denominator of which is the total square feet of Rentable
Area of the Premises before Landlord's recapture. The Additional Rent, to the
extent that it is calculated on the basis of the square feet of Rentable Area
within the Premises, shall be reduced to reflect Tenant's proportionate share
based upon the square feet of Rentable Area of the Premises retained by
Tenant after Landlord's recapture. Notwithstanding the foregoing, Landlord's
right to recapture the Premises pursuant to this Section 13.06 shall not
apply to a Transfer during the initial five (5) year term of this Lease.

Landlord determines that such proposed use involves a material risk of a release
or discharge of Hazardous Materials or a violation of any Health and Safety Laws
or that Tenant has not provided reasonable assurances of its ability to remedy
such a violation and fulfill its obligations under this Article 14. Landlord
acknowledges that the original Tenant uses liquid nitrogen in the conduct of

Tenant's use of such material on the Premises, provided Tenant shall handle,
use, store and dispose of such material in a safe and lawful manner, in

products are of a type customarily found in offices and households (such as
aerosol cans containing insecticides, toner for copies, paints, paint remover

Laws, including, but not limited to, the discharge of appropriately treated
Hazardous Materials into or through any sanitary sewer serving the Premises.
At Landlord's request, Tenant shall deliver copies of, or allow Landlord to
inspect, all such permits, licenses and approvals. All Hazardous Materials

and safety Laws. Tenant shall be responsible for the proper disposal of any
mercury-containing fluorescent lighting fixtures. Tenant shall perform any
monitoring, testing, investigation, clean-up, removal, detoxification,

required by any governmental agency or lender or reasonably recommended by
Landlord's environmental consultants as a result of (a) any release or
discharge or potential release or discharge of Hazardous Materials and
resulting in On-Site Contamination or Off-Site Contamination or (b) any
violation or potential violation of Health and Safety Laws that, in the case
of (a) or (b) is by Tenant or any successor or sublessee of Tenant or their
respective agents, contractors, employees, licensees or invitees
(collectively, "Remedial Work"). Landlord shall have the right to intervene
in any governmental action or proceeding involving any Remedial Work, and to
approve performance of the work, in order to protect Landlord's interests.

agreement, consent decree or other compromise with respect to any claims
relating to Hazardous Materials without notifying Landlord and providing ample
opportunity for Landlord to intervene.

14.4 COMPLIANCE WITH INSURANCE
REQUIREMENTS. Tenant shall comply with the requirements of Landlord's and
Tenant's insurers regarding Hazardous Materials and with such insurers'
recommendations based upon prudent industry practices regarding management of
Hazardous Materials.

14.5 INDEMNITY. Tenant shall indemnify, protect, defend and hold Landlord (and
its partners and their respective officers, directors, employees and agents),
the Premises, Building, Parking Areas, and all other areas of the Project
harmless from and against any and all liabilities, demands, penalties, fines,
claims, suits, judgments, actions, investigations, proceedings, costs and
expenses (including attorneys' fees and court costs) arising out of or in
connection with any breach of any provisions of this Article 14, directly or
indirectly arising out of any liability of Tenant under any Health and Safety
Law or associated with any On-Site Contamination or any Off-Site Contamination
which is caused, suffered or permitted to be brought upon, kept, used,
discharged, deposited or leaked in or about the Premises or any other portion of
the Project by Tenant or any of Tenant's assigns, agents, employees, contractors
or invitees or by anyone in the Premises other than Landlord, Landlord's agents,
employees or contractors, including, but not limited to, the use, generation,
storage, release, disposal or transportation of Hazardous Materials by Tenant,
or any successor or sublessee of Tenant, or their respective agents,
contractors, employees, licensees, or invitees, on, under or about the Premises
during the Term, and including, but not limited to, all consequential damages
and the cost of any Remedial Work. Any defense by Tenant pursuant to this
Article shall be by counsel reasonably acceptable to Landlord. Neither the
consent by Landlord to the use, generation, storage, release, disposal or
transportation of Hazardous Materials nor the strict compliance with all Health
and Safety Laws shall excuse Tenant from Tenant's indemnification obligations
pursuant to this Article 14. The foregoing indemnity shall be in addition to and
not a limitation of the indemnification provisions of Article 5.09 of this
Lease. Tenant's obligations pursuant to this Section 14.05 shall survive the
termination or expiration of the Lease.

14.6 NOTICE. Each party to this Lease shall notify the other party, in writing,
as soon as reasonably possible, and in any event within five (5) business days
after, any of the following: (a) a party has knowledge, or it has reasonable
cause to believe, that any Hazardous Material has been released, discharged or
is located on, under or about the Premises, whether or not the release or
discharge is in quantities that would otherwise be reportable to a public
agency; (b) a party receives any order of a governmental agency requiring any
Remedial Work pursuant to any Health and Safety Laws; (c) a party receives any
warning, notice of inspection, notice of violation or alleged violation, or a
party receives notice or knowledge of any proceeding, investigation of
enforcement action, pursuant to any Health and Safety Laws; or (d) a party
receives notice or knowledge of any claims made or threatened by any third party
against that party or the Premises relating to any loss or injury resulting from
Hazardous Materials or from violation of any Health and Safety Law. If the
potential risk of any of the foregoing events is material, the party having
notice of such event shall deliver immediate verbal notice to the other party,
in addition to written notice as set forth above. Landlord and Tenant agree to
deliver to one another copies of all test results, reports and business or
management plans required to be filed with any governmental agency pursuant to
any Health and Safety Laws.

14.7 DEFAULT. The material release or discharge of any Hazardous Material other
than as permitted by law or the in violation of any Hazardous Materials Law by
Tenant or any successor or sublessee of Tenant shall be a material default by
Tenant under the Lease. In addition to or in lieu of the remedies available
under the Lease as a result of such default, Landlord shall have the right,
without terminating the Lease, to require Tenant to suspend its operations and
activities on the Premises until Landlord is satisfied that appropriate Remedial
Work has been or is being adequately performed; Landlord's election of this
remedy shall not constitute a waiver of Landlord's right thereafter to declare a
default and pursue other remedies set forth in the Lease.

14.8 LANDLORD'S DISCLOSURE. Pursuant to the requirements of California Health
and Safety Code Section 25359.7, Landlord hereby notifies Tenant that Landlord
does not know, and does not have

<PAGE>

reasonable cause to believe, that any release of any Hazardous Material has come
to be located on or beneath the Premises, Building or Project.

15 . OFFSET STATEMENT, ATTORNMENT AND SUBORDINATION

15.1 ESTOPPEL CERTIFICATE. Within ten (10) days after request therefor by either
party, the other party shall deliver to the requesting party, in recordable
form, a certificate certifying (if such be the case, or otherwise setting forth
any exceptions thereto) that (a) this Lease is in full force and effect; (b) the
date of Tenant's most recent payment of Rent, or setting forth any exceptions
(c) that the certifying party has no defenses or offsets outstanding, or stating
those offsets or defenses claimed by the certifying party; (d) that to the
certifying party's knowledge, the requesting party has no defenses or offsets
outstanding, or stating those offsets or defenses claimed by the other party;
and (e) and any other information reasonably requested. Tenant's failure to
deliver said certificate in time shall be conclusive upon Tenant that: (i) this
Lease is in full force and effect, without modification except as may be
represented by Landlord; (ii) there are no uncured defaults in Landlord's
performance and Tenant has no right of offset, counterclaim or deduction against
Rent hereunder; and (iii) no more than one period's Base Rent has been paid in
advance. Landlord's failure to deliver said certificate in time shall be
conclusive upon Landlord that: (x) this Lease is in full force and effect,
without modification except as may be represented by Tenant; (y) there are no
uncured defaults in Tenant's performance; and (z) Tenant's representation as to
the amount of Base Rent that has been paid in advance is correct. Failure of a
party to deliver such a certificate to the other party within ten (10) days
following Landlord's request therefor shall be deemed such party's
acknowledgment of the correctness of the statements made in the foregoing
sentence and that the requesting party's mortgagee(s) and/or purchaser(s) may
rely on said statements.

15.2 ATTORNMENT. Tenant shall, in the event any proceedings are brought for the
foreclosure of, or in the event of exercise of the power of sale under any
mortgage or deed of trust made by the Landlord, its successors or assigns,
encumbering the Premises, or any part thereof, or in the event of termination of
a ground lease, if any, and if so requested, attorn to the purchaser upon such
foreclosure or sale or upon any grant of a deed in lieu of foreclosure and
recognize such purchaser as the Landlord under this Lease.

15.3 SUBORDINATION. The rights of Tenant hereunder are and shall be, at the
election of the mortgagee, subject and subordinate to the lien of such mortgage,
or the lien resulting from any other method of financing or refinancing, now or
hereafter in force against the Project, Building and/or Parking Area, and to all
advances made or hereafter to be made upon the security thereof; provided,
however, no such subordination shall be effective unless and until Tenant shall
have received a non-disturbance agreement in a recordable, commercially
reasonable form to the effect that neither this Lease nor any of the rights of
Tenant hereunder shall be terminated or subject to termination by any trustee's
sale, any action to enforce the security, or by any proceeding or action in
foreclosure unless an uncured Event of Default shall exist. If requested, Tenant
agrees to execute whatever documentation may be required to further effect the
provisions of this Article.

15.4 NON-DISTURBANCE. Within ten (10) days after execution of this Lease,
Landlord shall deliver to Tenant with respect to each mortgage, deed of trust,
ground lease or other monetary lien or encumbrance in force against the Project
as of the date hereof, a non-disturbance agreement from the mortgagee, ground
lessor, beneficiary of the deed of trust or other lienholder in a commercially
reasonable form. If Landlord, after commercially reasonable efforts, is unable
for any reason to deliver such non-disturbance agreements within such period,
Tenant's sole remedy shall be to cancel this Lease by delivering written notice
thereof to Landlord within five (5) days of the expiration of such ten (10) days
period.

be binding upon and shall inure to the benefit of the parties hereto and their
respective heirs, successors and legal representatives and their respective

whom the interest of the Landlord shall be vested and Landlord shall have no
obligation hereunder as to any claim arising after the transfer of its interest
in the Premises, subject to the provisions of Section 13.05. Any successor or

assignment to Tenant without the written consent of Landlord.

18 . MISCELLANEOUS

18.1 WAIVER. No waiver of any default or breach of any covenant by either party
hereunder shall be implied from any omission by either party to take action on
account of such default if such default persists or is repeated, and no express
waiver shall affect any default other than the default specified in the waiver,
and then said waiver shall be operative only for the time and to the extent
therein stated. Waivers of any covenant, term or condition contained herein by
either party shall not be construed as a waiver of any subsequent breach of the
same covenant, term or condition. The consent or approval by either party to or
of any act by either party requiring further consent or approval shall not be
deemed to waive or render unnecessary their consent or approval to or of any
subsequent similar acts.

18.2 EASEMENTS. Landlord reserves the right to (i) subdivide or alter the
boundaries of the Project and (ii) grant easements on the Project and dedicate
for public use portions thereof without Tenant's consent; provided, however,
that no such subordination, alteration, grant or dedication shall materially
unreasonably interfere with Tenant's use of the Premises pursuant to the terms
of this Lease. From time to time, and upon Landlord's demand, Tenant shall
execute, acknowledge and deliver to Landlord, in accordance with Landlord's
instructions, any and all documents, instruments, maps or plats necessary to

Lease and authorizing the persons executing this Lease to execute same for and
on behalf of Tenant.

18.6 ACCORD AND SATISFACTION. No payment by Tenant or receipt by Landlord of a
lesser amount than the Rent herein stipulated shall be deemed to be other than
on account of the Rent, nor shall any endorsement or statement on any check or
any letter accompanying any check or payment as Rent be deemed an accord and
satisfaction, and Landlord may accept such check or payment without prejudice to
Landlord's right to recover the balance of such Rent or pursue any other remedy
provided in this Lease.

18.7 LIMITATION OF LANDLORD'S LIABILITY. The obligations of Landlord under this
Lease shall not constitute personal obligations of the individual members,
partners, directors, officers, or shareholders of Landlord or any member of
Landlord, and in consideration of the benefits accruing hereunder to Tenant and
notwithstanding anything contained in this Lease to the contrary, Tenant hereby
covenants and agrees for itself and all of its successors and assigns that the
liability of Landlord for its obligations under this Lease shall be limited
solely to, and Tenant's and its successors' and assigns' sole and exclusive
remedy shall be against the real estate that is the subject of this Lease and

judgment and levy against the right, title, and interest of Landlord in the
Project, and out of insurance proceeds, rent or other income from the Project
receivable by Landlord or out of the consideration received by Landlord from the
sale or other disposition of all or any part of Landlord's right, title and
interest in the Project. Notwithstanding the foregoing, if Landlord is in
default of this Lease and, as a consequence, Tenant recovers a money judgment

demand by Tenant, then Tenant shall have the right to record a lien against the
Building or Project for the unsatisfied amount of the judgment.

liability company, a partnership or joint venture, the member or partners of
such entity shall not be personally liable and no partner of Landlord shall be
sued or named as a party in any suit or action, or service of process be made

and/or agents of such corporation shall not be personally liable and no
shareholder, director, officer, employee or agent of Landlord shall be sued or
named as a party in any suit or action, or service of process be made against
any shareholder, director, officer, employee, or agent of Landlord, except as
may be necessary to secure jurisdiction of the corporation. No partner,
shareholder, director, employee or agent of Landlord shall be required to answer
or otherwise plead to any service of process and no judgment will be taken or
writ of execution levied against any partner, shareholder, director, employee,
or agent of Landlord.

Tenant shall surrender the Premises to Landlord in good order, condition and
repair, except for reasonable wear and tear or as otherwise provided in Articles

termination of this Lease to be removed from the Premises and stored at Tenant's
expense, or, at Landlord's election said personal property thereafter shall
belong to Landlord without the payment of any consideration, subject to the
rights of any person holding a perfected security interest therein.

further such Rules and Regulations shall diminish Tenant's rights under this
lease.

18.17 NO NUISANCE. Tenant shall conduct its business and control its agents,

Broker and any commission owing to Landlord's Broker in connection with this
Lease, in accordance with a separate agreement between such brokers and
Landlord.

18.19 LANDLORD'S RIGHT TO PERFORM. Upon Tenant's failure to perform any
obligation of Tenant hereunder, including without limitation, payment of
Tenant's insurance premiums, charges of contractors who have supplied materials
or labor to the Premises, etc., Landlord shall have the right to perform such
obligation of Tenant on behalf of Tenant and/or to make payment on behalf of
Tenant to such parties, provided Landlord has first provided written notice to
Tenant and given Tenant ten (10) days to perform such obligation (unless another
cure period is provided herein). Tenant shall reimburse Landlord the reasonable

reimbursement of any amounts that may be expended by Landlord, plus interest at

time, by Bank of America, N.A. per annum, as Additional Rent.

this Lease, or by law, unless Landlord fails to perform the obligations required
of Landlord within a reasonable time, but in no event later than ten (10) days
after written notice by Tenant to Landlord and to the holder of any first
mortgage or deed of trust covering the Premises whose name and address shall

has failed to perform such obligation. If, however, the nature of Landlord's
obligation is such that more than ten (10) days are required for performance,
Landlord shall not be in default exist if Landlord commences performance within
such ten (10) day period and diligently prosecutes the same to completion.

such default materially interferes with Tenant's business operation in the
Premises, Tenant may give Landlord and the holder of any first mortgage or deed
of trust covering the Premises a second written notice specifying exactly the
nature of the Landlord's failure and its impact on Tenant's business operation
in the Premises and the further remedial action deemed necessary by Tenant. If
such remedial action is not undertaken within thirty (30) days of such second
written notice, Tenant shall be entitled to terminate this Lease, but in no
event earlier than thirty (30) days after the second notice to Landlord and the

Lease as a result of Landlord's default if Landlord is making diligent and
reasonable efforts to perform the obligations required of Landlord under this
Lease. Nothing herein contained shall be interpreted to mean that Tenant is
excused from paying any rent due hereunder as a result of any default by
Landlord.

equipment in connection with the Premises or Building or (ii) any failure to
furnish or delay in furnishing any services required to be provided by Landlord

reasonable control of Landlord or by the making of necessary repairs or
improvements to the Premises or to the Building, or the governmental or
third-party supplier limitation, curtailment, rationing or restriction on use of

hereunder or materially and adversely affect the leasehold interest hereby
created or Tenant's rights hereunder.

consent of the other. Either party may, at its sole cost and expense, record a
short form memorandum of this Lease in a form reasonably acceptable to the other

Execution of this Lease, entered into a lease of even date herewith ("Building A
Lease)) for the entire four (4) floors of a four-story building being

Diego, California, which building is commonly referred to as "Building B" of the
Project. Landlord and Tenant agree that for so long as Landlord owns both
Building B and the Building under this Lease, a default by Tenant under this
Lease shall constitute a default by Tenant under the Building B Lease, and a
default by Tenant under the Building B Lease shall constitute a default by
Tenant under this Lease. Additionally, Landlord and Tenant agree that for so
long as Landlord owns both Building B and the Building under this Lease, a
default by Landlord under this Lease shall constitute a default by Landlord
under the Building B Lease, and a default by Landlord under the Building B Lease
shall constitute a default by Landlord under this Lease.

         19.02 LETTER OF CREDIT. In addition to the Security Deposit and as
additional security hereunder, in the event Tenant fails, at any time during the
Term (including any Extensions) to maintain cash or cash equivalent reserves of
at least Ten Million Dollars ($10,000,000) (the "Cash Requirement"), then Tenant
shall, within ten (10) days after the date the Cash Requirement fails to be
satisfied, deliver to Landlord written notice thereof and a letter of credit in
an amount equal to six (6) times the then effective Monthly Rent. The letter of
credit shall be substantially in the form and of the substance of Exhibit F
attached hereto, and issued by Union Bank of California or another financial
institution reasonably acceptable to Landlord. Tenant shall be entitled to
replace any such letter of credit with a new letter of credit that satisfies
such conditions, and upon delivery of such replacement letter of credit by
Tenant to Landlord, Landlord shall deliver the old letter of credit to Tenant
and cooperate with Tenant in terminating the old letter of credit, including by
authorizing a full exoneration and release of the letter of credit. Landlord
shall be entitled to draw on the letter of credit if Tenant has not replaced the
letter of credit and the letter of credit is due to expire within ten (10) days
and before the end of the Term. If Landlord so draws on the letter of credit,
then Landlord shall hold the letter of credit proceeds as an additional security
deposit; provided, however, that if Tenant subsequently delivers a letter of
credit meeting the requirements set forth above, then Landlord shall immediately
release such proceeds to Tenant. Upon any default by Tenant which has not been
cured within the applicable time period after any notice required by this Lease,
including specifically but without limitation Tenant's obligation to pay rent or
abide by any of its obligations under this Lease, Landlord shall be entitled to
draw upon said letter of credit in the amount of the default(s) by the issuance
of Landlord's sole written demand to the issuing financial institution. Any such
draw shall be without waiver of any rights Landlord may have under this Lease or
at law or in equity as a result of the default. In the event that Tenant can
demonstrate by the delivery to Landlord of its audited financial statements
prepared in accordance with generally accepted accounting principles,
consistently applied, that Tenant has reestablished the Cash Requirement, then,
upon written request of Tenant, Landlord shall deliver the letter of credit to
Tenant and cooperate with Tenant in terminating the letter of credit, including
by authorizing a full exoneration and release of the letter of credit; provided,
however, if at any subsequent time Tenant shall fail to maintain the Cash
Requirement Tenant shall give written notice thereof to Landlord and cause a
replacement letter of credit to be delivered to Landlord in an amount equal to
six (6) times the then effective Monthly Rent, and on other terms of, the
original letter of credit. Tenant shall submit to Landlord annually during the
Term (including any Extension) on or before the first day of the fourth (4th)
calendar month of Tenant's fiscal year, Tenant's audited financial statements
for the preceding fiscal year prepared in accordance with generally accepted
accounting principles, consistently applied.

         19.06 USE OF ROOF. For so long as Tenant and any Affiliate Transferee,
in the aggregate, leases at least eighty percent (80%) of the Usable Area in the
Building, Tenant shall be entitled to install, maintain and operate on the roof
of the Building, for the purpose of Tenant's business, a limited number of
telecommunications, satellite and other devices that make use of the
electromagnetic spectrum ("Telecommunications Devices") as Landlord may approve
in writing, subject to the following requirements and subject always to
compliance with all covenants or restrictions of record as of the date hereof,
applicable laws, building codes, regulations and ordinances. All such

shall provide prior written notice to Landlord of Tenant's desire to install
such Telecommunications Devices on the roof of the Building, together with plans
and specifications for the

                                       2

installation of such Telecommunications Devices. Landlord shall review such
plans and specifications within ten (10) days after receiving such plans and
specifications from Tenant, and within such period notify Tenant if Landlord
approves the installation of such Telecommunications Devices or disapproves the
installation of such Telecommunication Devices, and if Landlord disapproves the
installation of such Telecommunication Devices, the reasons therefor. Landlord
may withhold its approval to the installation of Telecommunications Devices on
the roof of the Building if such Telecommunication Devices are visible from
other locations in the Project or the surrounding areas, pose any material risk
to the physical integrity of the Project or adversely affect the appearance of
the Building from surrounding areas. Landlord may condition it's approval of any
Telecommunications Devices on Tenant installing any walkways, screening or other
devices or material requested by Landlord. Tenant shall be responsible for any
installation and maintenance costs of any such Telecommunication Devices, as
well as any damage to the Building, including without limitation the roof,
arising out of or related to the installation or use by Tenant of any such
Telecommunications Device.

         19.07 ADDITIONAL PROVISIONS RELATING TO RULES AND REGULATIONS. Landlord
agrees not to change the name of the Project during the Term to include the name
of any competitor of the original Tenant. Landlord agrees that Tenant may use a
forklift or similar equipment in the shipping and receiving area on the ground
floor of the Premises so long as the use of such equipment is in full compliance
with Section 9.01 and Section 9.04 of this Lease and does not cause damage to
the Building or Project. Tenant's employees may, while traveling away from the
San Diego area for the business purposes of Tenant, leave vehicles in such area
of the Parking Area as is designated by Landlord for a period of not to exceed
seven (7) calendar days.

Tenant's Space Plan is subject to Landlord's approval. Within five (5) business
days after Tenant delivers to Landlord the Space Plan, Landlord shall deliver to
Tenant written notice of its approval or disapproval of the Space Plan. If for
any reason Landlord fails to expressly reasonably approve or disapprove the
Space Plan within the time period set forth in this Section, then each day of
delay in Landlord's approval or disapproval of the Space Plan beyond the time
period set forth in this Section shall be a Landlord-Caused Delay (as defined in
Section 8.1 of this Exhibit "D"). If Landlord disapproves the Space Plan,
Landlord and Tenant shall meet and confer within five (5) business days after
delivery of Landlord's notice disapproving the Space Plan and shall attempt in
good faith to reach agreement on the Space Plan. In the event Tenant's Space
Plan is not approved by Landlord, on or before the date set forth in the
Development Schedule for such approval, such dispute shall be submitted for
resolution pursuant to Article 11 of this Exhibit "D."

                  1.3.3 On or before September 15, 2001, Tenant agrees to submit

Improvement Consultants ("Tenant's Improvement Plans").

                  1.3.4 On or before September 15, 2001, Tenant agrees to submit
to the City of San Diego, complete and fully detailed Tenant's Improvement Plans
prepared by Tenant's Designer and Tenant's Improvement Consultants. Tenant's
Designer shall be responsible for the coordination with Tenant's engineers and
other consultants of submission of the Tenant's Improvements Plans to the City
as provided herein.

                  1.3.5 Fees of Tenant's Designer and Tenant's Improvement
Consultants in preparing Tenant's Improvement Plans shall be paid from the
Tenant Improvement Fund.

         1.4  APPROVAL OF TENANT'S IMPROVEMENT PLANS.

                  1.4.1 The design of, the quality of materials used in, and the
installation methods undertaken in the Premises, and Tenant's Improvement Plans,
shall be subject to the reasonable approval of Landlord after consultation with
the Project Architect, within the time periods set forth in Section 1.4.2, and
shall be in accordance with all City, County and State ordinances, rules and
regulations relating thereto.

                  1.4.2 Landlord shall reasonably approve or disapprove the
Tenant's Improvement Plans in writing within ten (10) business days after
Landlord's receipt of such documents. If for any reason Landlord fails to
expressly approve or disapprove the Tenant's Improvement Plans within the time
period set forth in this Section, then each day of delay in Landlord's approval
or disapproval of the Tenant's Improvement Plans beyond the time period set
forth in this Section shall be a Landlord-Caused Delay, as that term is defined
in Section 8.1 of this Exhibit "D". If Landlord reasonably disapproves any
portion of the Tenant's Improvement Plans, then Landlord shall specifically (a)
approve those portions which are acceptable to Landlord and (b) disapprove those
portions which are not acceptable to Landlord, specifying the reasons for such
disapproval and describing in detail the change Landlord requests for each item
disapproved ("Requested Change"). Tenant shall cause Requested Changes to be
made to the Tenant's Improvement Plans; provided, however, if Tenant does not
approve of a Requested Change, such dispute shall be resolved in accordance with
Article 11 of this Exhibit "D". A Requested Change

                                      -2-
<PAGE>

which is non-material and/or mutually agreed upon by Landlord and Tenant (a
"Non-Material Change") shall be made to the Tenant's Improvement Plans by
Tenant's Designer and any delay incurred as a result of such Non-Material Change
shall be a Force-Majeure Delay; provided, if Landlord and Tenant are unable to
agree on whether a Requested Change is a Non-Material Change, such dispute shall
be resolved in accordance with Article 11 of this Exhibit "D".

                  1.4.3 As a part of Landlord's review and approval of Tenant's
Improvement Plans described in Sections 1.4.1 and 1.4.2 above, Landlord shall
review Tenant's Improvement Plans for their conformance with provisions
contained within this Exhibit "D" and Landlord's Plans. Where Tenant's
Improvement Plans, as approved by Landlord, conflict with this Exhibit "D", the
provisions of this Exhibit "D" shall prevail. Landlord's approval of Tenant's
Improvement Plans shall not be deemed to certify that Tenant's Improvement Plans
comply with building codes and shall not relieve Tenant of the responsibility to
verify that Tenant's Improvement Plans comply with all of the requirements set
forth in Section 1.3.1 hereof.

                  1.4.4 Any subsequent changes, modifications or alterations to
Tenant's Improvement Plans requested by Tenant after Landlord's approval thereof
and before completion of Tenant's Improvement Work shall be processed in the
manner provided in Section 1.7 of this Exhibit "D" and any additional reasonable
costs and expenses incurred by Landlord in connection with said processing,
including but not limited to additional fees of Project Architect and its
consultants, shall be paid from the Tenant Improvement Fund. No such changes,
modifications or alterations in said approved drawings shall be made without the
written consent of Landlord after written request therefor by Tenant.

         1.5 BUILDING PERMIT FOR TENANT'S IMPROVEMENT WORK. Tenant's Designer
(as defined in Section 1.3.1 of this Exhibit "D") shall be responsible for
obtaining a building permit for the construction of Tenant's Improvement Work
and all other required governmental approvals and permits from the City of San
Diego ("City"). If the City rejects Tenant's Improvement Plans and thereby
prevents the issuance of a building permit, Tenant shall immediately, but in all
events within three (3) business days of notice from the City, make all
necessary corrections required by the City. If the City requires a change to the
Tenant's Improvement Plans (a "City-Required Change"), the City-Required Change
shall be made to the Tenant's Improvement Plans by Tenant's Designer or
engineers or other consultants as appropriate. Any delay incurred as a result of
such City-Required Change shall be a Force Majeure Delay, unless such
City-Required Change resulted from a failure of Tenant's Designer or engineers
or other consultants to submit to the City complete and fully dimensioned
Tenant's Improvement Plans or a failure of Tenant's Designer or engineers or
other consultants to conform their performance of their duties with respect to
the Tenant's Improvement Plans to customary professional standards of their
respective professions in the City of San Diego (in which event, such change
shall be an "Designer Caused Change"). Any delay occasioned by an
Designer-Caused Change shall be a Tenant-Caused Delay. Subject to Section 1.8,
any change to Tenant's Improvement Plans requested by Landlord after Landlord's
approval thereof (a "Landlord Change") shall be made to the Tenant's Improvement
Plans by Tenant's Designer at no cost to Tenant (with such cost to be borne by
Landlord and not charged against the Tenant Improvement Fund) and any delay
incurred as a result of such Landlord Change shall be a Landlord-Caused Delay.
If Landlord and Tenant are unable to agree on whether a change or addition to
the Tenant's Improvement Plans is a Landlord Change, Tenant Change,
City-Required Change or Designer-Caused Change, then such dispute shall be
resolved in accordance with Article 11 of this Exhibit "D". Upon the City's
approval of Tenant's Improvement Plans and permit application, Tenant shall pick
up and deliver to Landlord (or cause Tenant's Designer to pick up and deliver to
Landlord) the building permit and the approved set of Tenant's Improvement Plans
marked "For Construction". Landlord shall pay for the plan check and general
building permit fees required on the permit application from the Tenant
Improvement Fund, provided the building permit is issued. Landlord shall also
pay required sewer connection fees to the City upon issuance of the building
permit from the Tenant Improvement Fund. Tenant shall pay any other fees
required in connection therewith not otherwise payable from the Tenant
Improvement Fund as provided herein. Tenant shall apply for and obtain all
approvals and permits from the local health

department, as required. If Tenant's Improvement Plans are not approved as
provided herein or Tenant does not obtain all required building permits for
Tenant's Improvement Work, then Tenant shall, upon Landlord's written request,
forthwith reimburse Landlord for all fees paid by Landlord from the Tenant
Improvement Fund.

         1.6  CONSTRUCTION OF LANDLORD'S WORK, TENANT'S IMPROVEMENT WORK AND
TENANT'S WORK.

                  1.6.1 Landlord agrees to construct, at its own expense, as
soon as practical after Landlord's Plans have been approved by the City and a
building permit has been issued, within the time period set forth in the
Development Schedule, those improvements described as "Landlord's Work" in
Article 2 hereof in accordance with Landlord's Plans.

                  1.6.2 Landlord agrees, as soon as practical after completion
of Landlord's Work to the point where it can commence construction of Tenant's
Improvement Work and after receipt from Tenant of the building permit for the
Tenant's Improvement Work, to construct, within the time period set forth in the
Development Schedule, those improvements described as "Tenant's Improvement
Work" in Article 3 hereof in accordance with the approved Tenant's Improvement
Plans. The costs and expenses incurred by Landlord in connection with such
construction of Tenant's Improvement Work shall be paid from the Tenant
Improvement Fund, except that in no event shall the cost of cabling and
equipment and the expense of installing same be paid out of the Tenant
Improvement Fund, as such cost and expense shall be paid separately by Tenant.

                  1.6.3 Upon Substantial Completion of the Premises, Tenant
shall accept the Premises in the condition in accordance with the Lease and
subject, however, to Landlord's obligations under Section 1.6.8 of this Exhibit
"D". Tenant's acceptance of possession shall operate to waive any right Tenant
may have to terminate this Lease due to delayed delivery of possession. Landlord
shall deliver a copy of the Certificate of Occupancy to Tenant within ten (10)
days of its issuance.

                  1.6.4 In the event Tenant enters into possession of the
Premises prior to Substantial Completion of the Premises for the purpose of
performing Tenant's Work, Tenant agrees to indemnify, defend and hold Landlord
harmless from any loss or of damage to Tenant's or Tenant's contractor's
property, completed work, fixtures, equipment, materials or merchandise, or from
liability for death of or injury to any person, except to the extent same be
caused by the negligence of Landlord or its agents.

                  1.6.5 Tenant agrees, at its own expense, to construct
diligently and continuously to completion those improvements described as
"Tenant's Work" in Article 4. Tenant's Work shall comply with all City, County
and State ordinances, rules and regulations relating thereto and shall not be
constructed in a manner inconsistent with the approved Tenant's Improvement
Plans.

                  1.6.6 From the commencement of Landlord's Work until the
completion of Tenant's Improvement Work, Landlord shall obtain and maintain or
cause to be maintained public liability and worker's compensation insurance in
accordance with the Lease. From the commencement until the completion of
Tenant's Work, Tenant shall obtain and maintain, at Tenant's expense, public
liability and worker's compensation insurance in accordance with the Lease.

                  1.6.7 If a permit is required to construct Tenant's Work,
Tenant shall deliver a completed, signed-off inspection card to Landlord within
ten (10) days of completion of Tenant's Work or Tenant's opening for business,
whichever occurs first. If Tenant contracts with any person or entity to perform
any part of Tenant's Work, Tenant shall obtain and record a Notice of Completion
promptly following completion of Tenant's Work and shall promptly forward a
certified copy thereof to Landlord.

                  1.6.8 On or before the date Tenant occupies the Premises for
the purpose of conducting its business therein, Landlord and Tenant shall
conduct a walk-through inspection of the Premises and

                                      -4-

<PAGE>

shall jointly prepare a list of initial construction defect items related to
Tenant's Improvement Work and Tenant's Work that need to be corrected. Landlord
shall cause Landlord's Contractor to correct such initial construction defect
items within thirty (30) days thereafter, provided, however, if by the nature of
such correction more than thirty (30) days is required to effect such
correction, Landlord shall not be in default hereunder if such correction is
commenced within such thirty (30) day period and is diligently pursued to
completion.

         1.7 Tenant Changes. Any changes requested by Tenant to Landlord's Plans
and Landlord's Work after the date of this Lease and any changes to Tenant's
Improvement Plans and Tenant's Improvement Work requested by Tenant after
approval of the Tenant's Improvement Plans by Landlord shall be requested and
instituted in accordance with the provisions of this Section 1.7 and shall be
subject to the written approval of Landlord after consultation with the Project
Architect.

                  1.7.1 From time to time after the Tenant's Improvement Plans
have been approved by Landlord, Tenant may request changes to the Tenant's
Improvement Plans or request changes to the Tenant's Improvement Work already
completed ("Tenant Changes") by notifying Landlord in writing of the nature and
extent of any such Tenant Change and, if the nature of such Tenant Change
requires revisions to Tenant's Improvement Plans, then Tenant's Designer shall
revise Tenant's Improvement Plans. Such notice must be signed by at least one of
Tenant's Construction Representatives (as that term is defined in Section 9.1 of
this Exhibit "D") or Landlord shall not be required to process such Tenant
Change request. Landlord shall, before proceeding with a Tenant Change, use its
best efforts to respond to Tenant as soon as is reasonably possible with an
estimate of (i) the time it will take Landlord to analyze the requested Tenant
Change, and (ii) the architectural and engineering fees and costs which will be
incurred in order to analyze the requested Tenant Change, and thereafter submit
to Tenant in writing, within seven (7) business days after Tenant notifies
Landlord of the requested Tenant Change (or such longer period of time as is
reasonably required depending on the extent of Tenant's Change request), an
analysis of the additional cost or savings involved, including without
limitation architectural and engineering costs and the period of time, if any,
that the Tenant Change will extend the time for completion of Tenant's
Improvement Work. Any delay caused by Landlord's failure to deliver to Tenant
Landlord's analysis of a Tenant Change within the time herein provided shall be
a Landlord-Caused Delay. If Tenant fails to expressly approve or disapprove in
writing Landlord's submission within five (5) business days of receipt thereof,
then each day of delay in the Tenant's approval or disapproval of Landlord's
submission beyond such five (5) business day period shall be a Tenant-Caused
Delay. The time for completion of Tenant's Improvement Work shall be extended
one day for each day of delay caused by analyzing and processing Tenant's
request for a Tenant Change whether or not the cost or savings and the extension
of time for completion of Tenant's Improvement Work, if any, is approved by
Tenant and such delay shall be a Tenant-Caused Delay.

                  1.7.2 If Tenant approves in writing the cost or savings and
the extension in the time for completion of the Tenant's Improvement Work, if
any, Landlord shall cause the approved Tenant Change to be instituted. The time
for completion of the Tenant's Improvement Work shall be extended one day for
each day of delay caused by instituting the Tenant Change requested by Tenant
and such delay shall be a Tenant-Caused Delay. Delays resulting directly from
Tenant's Designer's failure to modify the Tenant Improvement Plans to the extent
necessary to determine the cost or savings and the extension in the time for
completion of Tenant's Improvement Work as a result of a Tenant Change requested
by Tenant shall be Tenant-Caused Delays.

                  1.7.3 Tenant shall reimburse Landlord, at its sole cost and
expense, for all architectural and engineering fees and costs incurred by
Landlord in connection with modifications and revisions to Landlord's Plans or
Tenant's Improvement Plans, which result from a Tenant Change request and/or
instituting the Tenant Change.

                  1.7.4 Notwithstanding anything to the contrary in this Section
1.7, Tenant shall not be

                                      -5-

<PAGE>

responsible for architectural and/or engineering fees and costs incurred by
Landlord and the Project Architect and delays which result from a Tenant Change
request if such fees and costs and/or delays are immaterial in nature; provided,
however, if Landlord and Tenant are unable to agree upon whether such
architectural and/or engineering fees and costs and/or delays which result from
a Tenant Change requested by Tenant are immaterial, then such dispute shall be
resolved in accordance with Article 11 of this Exhibit "D".

                  1.7.5 Landlord and Tenant agree that time and strict punctual
performance are of the essence with respect to this Article 1 and that each
shall use due diligence in performing their respective obligations pursuant to
this Article 1.

         1.8 Landlord Changes. Any changes requested by Landlord to Tenant's
Improvement Plans and Tenant's Improvement Work after Landlord's approval of
Tenant's Improvement Plans, other than changes required by the City or due to
the error or omission of Tenant's Designer or any party working for or on behalf
of Tenant (collectively a "Landlord Change"), shall be subject to the written
consent of Tenant, which consent shall not be unreasonably withheld or delayed;
shall be made at no cost to Tenant; and any delay incurred as a result of such
Landlord Change shall be a Landlord-Caused Delay.

                  LANDLORD'S USE OF A CONTRACTOR, COST ESTIMATE


         6.1 CONTRACTOR SELECTION. Subject to the conditions set forth in this

         6.2  ESTIMATE OF TENANT'S IMPROVEMENT WORK COSTS.

                  6.2.1 On or before the date Tenant submits the Tenant
Improvement Plans to the City for Plan Check, Landlord's Contractor shall submit
to Landlord and Tenant a list of acceptable subcontractors from whom Landlord's
Contractor desires to receive bids for the Tenant's Improvement Work required by
the Tenant Improvement Plans.. All Tenant's Improvement Work shall be bid, other
than general condition items. A minimum of three subcontractors per trade shall
be designated on such list. Landlord and Tenant shall have a right to disapprove
in writing any subcontractors shown on the list within the time set forth on the
Development Schedule and to propose up to two (2) subcontractors from which
Landlord's Contractor will be required to solicit bids unless Landlord has a
reasonable objection to such proposed subcontractors. Each day of delay in
approving or disapproving a subcontractor for each trade beyond the time period
set forth in the Development Schedule shall be a Tenant-Caused Delay or
Landlord-Caused Delay, as the case may be, as determined by the Construction
Panel.

                  6.2.2 From bids received by Landlord's Contractor from
approved subcontractors, Landlord's Contractor shall prepare a cost estimate of
the Tenant's Improvement Work ("Cost Estimate").

                                      -7-

<PAGE>

Such Cost Estimate shall include the entire cost of the construction and all

set forth in the Development Schedule, the Cost Estimate prepared by Landlord's
Contractor for Tenant's approval.

         6.3  TENANT APPROVAL OF COST ESTIMATE.

receipt of the Cost Estimate, notify Landlord in writing of either (i) Tenant's
approval of the Cost Estimate or (ii) Tenant's disapproval of the Cost Estimate
and specific instructions to Landlord to reduce the scope of Tenant's
Improvement Work.

Landlord to reduce the scope of Tenant's Improvement Work, and the scope
reduction complies with the requirements of Section 1.7, and Tenant delivers to
Landlord revisions to Tenant's Improvement Plans prepared by Tenant's Designer,
if required, then Landlord shall cause Tenant's Improvement Plans, as revised,
to be re-bid in accordance with Section 6.2 and shall cause a revised cost
estimate to be prepared by Landlord's Contractor and delivered to Tenant
("Revised Cost Estimate"). Tenant's approval or disapproval of the Revised Cost

                  6.3.3 If Tenant fails to expressly approve or disapprove the
original Cost Estimate or any Revised Cost Estimate within the time periods set
forth in this Section 6.3, then each day of delay in Tenant's approval of the
original Cost Estimate or any Revised Cost Estimate or any subsequent cost
estimate beyond the time periods set forth in this Section 6.3 and any delay in
preparing a Revised Cost Estimate shall be a Tenant-Caused Delay.

                  6.3.4 Within ten (10) days after Tenant approves the original
Cost Estimate or any Revised Cost Estimate, Landlord shall enter into a
construction contract with Landlord's Contractor for construction of Tenant's
Improvement Work.

                  6.3.5 For each trade, Landlord's Contractor shall contract
with the lowest responsible bidder. Landlord's Contractor shall enter into a
stipulated sum contract with each subcontractor for the performance of such
subcontractor's work. Landlord shall compensate Landlord's Contractor for

                                    plus

                           (c)      a contingency equal to five percent (5%) of
                                    the costs described in clauses (a) and (b);
                                    plus

                  6.3.6 Landlord shall provide Tenant a copy of the fully
executed construction contract for

be entitled to be paid from Tenant Improvement Fund a construction management
fee ("Landlord's Construction Management Fee") of an amount equal to Fifty Cents
($.50) per square feet of Usable Area in the Premises.

                  6.3.7 If any dispute should arise between Landlord and Tenant
as to whether a delay under the provisions of this Section 6.3 is a
Landlord-Caused Delay or Tenant-Caused Delay, then such dispute shall be
resolved in accordance with Article 11 of this Exhibit "D".

                                    ARTICLE 7

                          TENANT'S USE OF A CONTRACTOR

         7.1 CONTRACTOR SELECTION. Tenant may select any contractor ("Tenant's
Contractor") reasonably approved by Landlord for the construction of Tenant's
Work provided such contractor is bondable and meets all licensing and insurance

contractor's work in any area of the Project.

penetration by Tenant.

                  (d) Tenant's Contractor shall store all construction materials
and contain all operations

Tenant shall immediately undertake such action as may be necessary to eliminate
such dispute or potential dispute, including without limitation (a) removing all
disputants from the job site until such time as the labor dispute no longer
exists, (b) seeking an injunction in the event of a breach of contract between
Tenant and Tenant's Contractor and (c) filing appropriate unfair labor practice
charges in the event of a union jurisdictional dispute.

                  (j) Prior to the commencement of construction, Tenant shall
give written notice to Landlord thereof and, if the cost of the Tenant's Work
exceeds Two Hundred Thousand Dollars ($200,000), obtain or cause Tenant's
Contractor to obtain payment and performance bonds covering the faithful
performance of the contract for the construction of Tenant's Work and the

Development Schedule and this Exhibit "D"; (ii) delays defined as Tenant-Caused
Delays pursuant to this Exhibit "D"; and (iii) delays resulting from Tenant's
request for materials, finishes or installations which are unavailable and
nonstandard (other than those typical for improving buildings as offices). It is
the parties' intent that the Tenant's Improvement Work be Substantially Complete
on or before March 22, 2002, provided Tenant's Designer submits Tenant's
Improvement Plans to the City of San Diego for the building permit purposes on
or before September 15, 2001, and the City approves the Tenant's Improvement
Plans and issues building permits for same on or before December 15, 2001.

                  (d) "Landlord-Caused Delays" shall mean (i) those delays,
exclusive of Force-Majeure Delays, caused by the failure of Landlord, Project
Architect, Landlord's Contractor, materialmen, construction managers or other
representatives of Landlord to act within the time limits set forth in the
Development Schedule and this Exhibit "D"; and (ii) delays defined as
Landlord-Caused Delays pursuant to this Exhibit "D"; and

                  (e) "City-Required Change" shall mean any change to the
Tenant's Improvement Plans submitted to the City of San Diego as a condition to
its approval of such Plans (except for changes to Tenant's Improvement Plans
required by the City as a result of a Landlord Change). Any City-Required Change
shall be deemed Tenant-Caused Delays, except as provided in Section 1.5.

         8.2  COMPLETION OF THE WORK AND COMMENCEMENT DATE.

                  8.2.1 Landlord shall use its best efforts to Substantially
Complete Landlord's Work and Tenant's Improvement Work on or before the
"Estimated Term Commencement Date" as such Estimated Term Commencement Date may
be extended pursuant to the terms of this Exhibit "D". The Estimated Term
Commencement Date shall be extended one day for each day of delay in Substantial
Completion of Landlord's Work and Tenant's Improvement Work resulting from
Tenant-Caused Delays.

                  8.2.2 The Estimated Term Commencement Date shall be extended
one day for each day of delay in Substantial Completion of Landlord's Work and
Tenant's Improvement Work resulting from Force Majeure Delays, provided that the
maximum period of extension of the Estimated Term Commencement Date resulting
from Force Majeure Delays shall not exceed sixty (60) days.

                  8.2.3 The Term Commencement Date and Tenant's obligation to
pay Basic Annual Rent and Additional Rent shall be advanced one day for each day
of delay in Substantial Completion of Landlord's Work and Tenant's Improvement
Work which result from Tenant-Caused Delays; provided, however, in no event
shall the Term Commencement Date or Tenant's obligation to pay Base Rent occur
before the date set forth in the Base Lease Information of the Lease as the
Estimated Term Commencement Date (without any adjustments thereto).

         8.3 CALCULATIONS OF DELAYS/UPDATE OF DEVELOPMENT SCHEDULE. Any delay in
Landlord's or Tenant's performance beyond the date and time for such performance
set forth in the Development Schedule shall be a Force-Majeure Delay, a
Tenant-Caused Delay or a Landlord-Caused Delay as determined in accordance with
the terms and conditions of this Exhibit "D". Landlord-Caused Delays,
Tenant-Caused Delays and Force-Majeure Delays shall be allocated in accordance
with the following procedure: Force-Majeure Delays shall be applied first when
extending the Estimated Term Commencement Date, whether Landlord-Caused Delays
and/or Tenant-Caused Delays are concurrent or contributive. Landlord-Caused
Delays and Tenant-Caused Delays which are concurrent or contributive shall be
deemed Force-Majeure Delays. Landlord-Caused Delays, exclusive of Force-Majeure
Delays and Tenant-Caused Delays, shall be Landlord-Caused Delays. Tenant-Caused
Delays, exclusive of Force-Majeure Delays, and Landlord-Caused Delays shall be
Tenant-Caused Delays. By way of example, if the completion date is extended ten
(10) days for Force-Majeure Delays and during such ten-

                                      -11
<PAGE>

day period there are three (3) days of Tenant-Caused Delays and five days of
Landlord-Caused Delays, all ten (10) days of delays will be Force-Majeure
Delays. If the completion date is extended ten (10) days, two (2) days of which
are Force-Majeure Delays which occur concurrently with Landlord-Caused Delays,
five (5) days of which are Tenant-Caused Delays which occur concurrently with
Landlord-Caused Delays, and three (3) days of which are Landlord-Caused Delays,
exclusive of Force-Majeure Delays and Tenant-Caused Delays, the delay period
shall be allocated as follows: seven (7) days of Force-Majeure Delays and three
(3) days of Landlord-Caused Delays. At each weekly on-site Work review meeting
(unless a less frequent schedule is mutually agreed upon by the parties),
Landlord and Tenant, through their designated construction representatives,
shall update the Development Schedule and account for and allocate all
Force-Majeure Delays, Landlord-Caused Delays and Tenant-Caused Delays in
accordance with this Section 8.3; provided, however, if Landlord and Tenant,
through their designated construction representatives are unable to agree on the
allocation of Force-Majeure Delays, Landlord-Caused Delays and Tenant-Caused
Delays, then such dispute shall be resolved in accordance with Article 11 of
this Exhibit "D". Notwithstanding anything in this Exhibit "D" to the contrary,
if a Force-Majeure Delay, a Landlord-Caused Delay and/or a Tenant-Caused Delay
are/is deemed to have occurred pursuant to this Exhibit "D" but such delay has
no effect on the critical path of the Development Schedule, then the Development
Schedule shall govern and such delay shall be deemed not to have occurred.

                                   DEVELOPMENT

         9.1 TENANT'S CONSTRUCTION REPRESENTATIVES. Tenant designates Paul
Stambo, an employee of Tenant (or such other individuals designated as a
construction representative) as Tenant's construction representatives ("Tenant's
Construction Representatives") in connection with Tenant's Improvement Work.
Tenant's Construction Representatives shall be allowed complete access to the
Building during construction and shall participate in all meetings with
Landlord's Contractor and subcontractors involved in the construction of
Tenant's Improvement Work. Tenant's Construction Representatives are the only
individuals authorized to approve each Change requested by Tenant pursuant to
Section 1.7 of this Exhibit "D". Any questions arising during construction shall
be directed to Tenant's Construction Representatives. Notwithstanding anything
to the contrary in this Exhibit "D", any and all changes requested by Landlord
to be made to the Landlord's Plans or Tenant's Improvement Plans, or changes in
construction of the Building Shell, Land Improvements and/or Tenant
Improvements, shall be approved by Tenant prior to implementing such change,
which approval shall not be unreasonably withheld or delayed. Such change (i)
must be consistent with Landlord's Plans and the approved Tenant's Improvement
Plans, as modified by any Changes, and (ii) shall be documented in writing and
Tenant shall give approval by having Tenant's Construction Representatives sign
an appropriate change order.

         9.2 DELIVERY OF THE PREMISES. Landlord shall deliver the Premises to
Tenant upon Substantial Completion of Tenant's Improvement Work in clean and
operating condition, subject to punch-list items. For purposes of this Section
9.2, the term "clean and operating condition" shall include the following: (a)
tile floors wet mopped, waxed and buffed and carpets vacuumed; (b) walls and
partitions cleaned and all holes filled and touched up; (c) all glass cleaned on
both sides; (d) trash, dirt and left-over materials shall be removed from the
Building entrance area; (e) air-conditioning, heating and ventilating systems
shall be in operating condition suitable for Tenant's occupancy in the Building;
(f) plumbing, electrical and elevator systems shall be in good operating
condition; and (g) the Building shall be in good condition and all site work,
including without limitation, hardscape, landscape, storm drainage, parking lot
striping and parking lot cleaning shall be complete. Punch-list items shall mean
such minor pick-up work as would not materially interfere with Tenant's
occupancy and use of the Premises for the purpose for which it is to be used;
provided, however, in no event shall punch-list items include work which would
unreasonably interfere with Tenant's use of such facilities for the purpose for
which they are intended.

         9.3 AS-BUILT DRAWINGS. Landlord shall maintain a set of "as-built"
drawings of the Premises, which shall be available for inspection by Tenant at
the office of Landlord during normal business hours.

                         CONSTRUCTION DISPUTE RESOLUTION

         11.1 DISPUTE RESOLUTION. If any dispute arises in connection with this
Exhibit "D", such dispute shall be resolved in accordance with this Article.
Such dispute shall be determined by a panel consisting of one representative of
Landlord, one of Tenant's Construction Representatives (or another party
designated by Tenant), Project Architect, Tenant's Designer and a fifth party
that has extensive development and construction experience in the construction
of comparable office buildings of the San Diego County area selected in
accordance with Section 11.3 of this Article (the "Construction Panel").

         11.2 NOTICE. All disputes to be determined in accordance with this
Article shall be raised by notice to the other party, which notice shall state
with particularity the nature of the dispute and the demand for relief, making
specific reference by Section number and title to the provision of this Exhibit
"D" alleged to give rise to the dispute. Such notice shall also refer to this
Article.

         11.3 SELECTION OF FIFTH PARTY/COSTS. Landlord's representative,
Tenant's representative, Project Architect and Tenant's Designer shall mutually
and promptly select a fifth party who meets the qualifications set forth in
Section 11.1 of this Article. In the event a selection is not made within two
(2) days after demand for resolution is made, the fifth party shall, upon the
request of either party, be appointed by the then-president of the Association
of General Contractors of San Diego County. All proceedings contemplated by this
Section shall take place at the location for all job-site meetings, unless the
Construction Panel mutually agrees to another location. The cost for the fifth
party's services shall be paid by the non-prevailing party in the dispute being
determined by the Construction Panel, unless the Construction Panel determines
otherwise.

         11.4 INTERPRETATION AND RESOLUTION. In determining any dispute, the
Construction Panel shall apply the pertinent provisions of this Exhibit "D"
without departure therefrom in any respect. The Construction Panel shall not
have the power to add to, modify or change any of the provisions of this Exhibit
"D"; but this provision shall not prevent in any appropriate case the
interpretation, construction and determination by the Construction Panel of the
applicable provisions of this Exhibit "D" to the extent necessary in applying
the same to the matters to be determined by the Construction Panel. As part of
resolving a dispute, the Construction Panel shall determine the days of delay in
completing the Landlord's Work and Tenant's Improvement Work which directly
result from the dispute being considered by the Construction Panel, if any. The
days of delay shall be designated as either Tenant-Caused Delays,
Landlord-Caused Delays or Force-Majeure Delays or any combination of the three
types of delay, as determined by the Construction Panel.

         11.5 CONTINUED PERFORMANCE. During any proceedings pursuant to this
Article, Landlord and Tenant shall, to the extent possible, continue to perform
and discharge all of their respective obligations under this Exhibit "D" and the
Lease.

         11.6 BINDING RESOLUTION. The Construction Panel shall meet within two
(2) business days of the fifth party being selected as a member of the
Construction Panel and the Construction Panel shall thereafter resolve the issue
in dispute within two (2) business days, unless it is mutually agreed among the
Construction Panel members that additional time is necessary to resolve the
dispute, but in no event

                                      -13-

shall such additional time exceed five (5) business days. Landlord and Tenant
agree that time and strict punctual performance are of the essence with respect
to each provision of this Exhibit "D" and that any and all decisions of the
Construction Panel as to the matter in dispute shall be binding upon both
Landlord and Tenant.
